Description: The invention preferably relates to a mobile portable stapling device for driving fasteners, such as in particular staples, into an object, comprising a housing device with a main housing section and a handle section which extends away from the main housing section, an ejection device being arranged in the main housing section , by means of which a fastener can be accelerated in order to eject the fastener from an outlet opening of the stapling device, a magazine device for receiving a supply of fasteners on the stapling device, a drive device for the ejecting device, which comprises an electric motor, and an energy supply means, in particular as Energy storage means, such as a rechargeable electric accumulator, is formed, which is or can be electrically connected to the electric motor, at least one outlet semittel with an operable shutter, a fastening means by means of the thus set in motion ejection device is through the actuation of at least accelerated and ejected from the outlet opening, wherein the actuatable trigger is arranged in the region of the handle portion of the housing;
Portable staplers that use a fluid, particularly compressed air, to accelerate fasteners such as staples, nails, clamps, and the like, and to drive these fasteners into objects are well known. Fastener drive tools of this type are used, for example, in the manufacture of furniture for attaching covers, for example leather covers, to furniture or for producing a bottom or lid closure of cardboard boxes. Depending on the field of application, staplers can differ in their basic construction. However, such pneumatic staplers generally always have a piston which can be moved in a cylinder between an upper and a lower dead center. A fastener drive member is disposed within the piston line of motion and is used to contact and eject the fasteners inserted into the fastener drive track from a magazine assembly. Pneumatic nail fastener driving tools are known which are provided with means for switching between two modes, in one mode each activation of the trigger results in a single shot of a fastener and in the other mode each activation of the trigger results in a plurality of successive shots leads as long as the trigger is activated and / or a mechanical contact of a microswitch in the area of a contact surface of the tacking nail device detects contact with a base.
There are also portable staplers known, which are additionally provided with pliers elements with which the legs of staples are bent after they enter a box. Stapling devices of this type are used above all to produce closures on cardboard boxes, in particular for closing lid wings of the cardboard boxes. With this type of stapler, it is necessary to coordinate the ejection movement with the movement of the pliers elements in order to grasp the ejected two-legged clamps with the pliers elements when they have already penetrated the cardboard box and the two legs of the respective clamps in the direction of one Bend the base leg of the clip. Such a portable portable stapler is known for example from EP 2 679 344 A2. In contrast to most other staplers currently on the market, the cardboard box stapler from EP 2 679 344 A2 is driven electrically and not pneumatically. For this purpose, the stapler from EP 2 679 344 A2 has a direct current electric motor which is fed by an accumulator and integrated in the portable portable stapler. The electric motor and its accumulator are accommodated in a housing part of the stapler, which is located between the handle of the stapler and the magazine for the staple supply, in the immediate vicinity of the magazine. With this stapler, it cannot be satisfied that the magazine cannot be easily operated due to the housing part of the motor. In particular, when the stapler is operated, the housing part of the motor blocks a clear view of the magazine, for example to visually check the remaining amount of staples in the magazine.
The invention is therefore based on the object to improve an industrial or commercial stapling device of the type mentioned in that the magazine device is more user-friendly controllable and more accessible.
This object is achieved in a stapling device of the type mentioned in accordance with the invention in that the electric motor is now arranged in the handle section in accordance with the invention and its axis of rotation is non-parallel with a longitudinal axis of an acceleration path of the expeller. According to the invention, provision is therefore made not to achieve better accessibility of the magazine by arranging the magazine at a different location or by redesigning it. Surprisingly, the accessibility of the magazine device can be considerably improved in that the electric motor is not only arranged at a greater distance than previously from the magazine device. By integrating the electric motor into the handle section of the housing, the motor can be accommodated in a housing part that must be present anyway for reasons other than the mounting of the motor. A separate housing section of the stapling device and its weight, which is only caused by the motor, can thus be avoided and the handle can also be supplied for a purpose other than its actual use.
The measure according to the invention also leads in a surprising manner to an ergonomic improvement, since the weight of the motor and possibly a gear, including the articulation or connection of the drive to an expulsion or outlet mechanism, is arranged in the handle or at least close to the handle. The end
CH 713 984 A2 to the motor and the weight resulting from the further components of the motor assigned to the motor thus generates no, or at most only a small, torque around the point at which the operator holds and handles the stapling device during its operation. The operator therefore has to apply less force to handle the stapling device and is therefore less tired. In a preferred embodiment of the invention, at least part of the motor, preferably the entire motor, can be arranged directly in and / or below the region of the handle section with which the operator grips the handle section and thereby holds the stapling device.
The advantages mentioned can be further increased if a motor downstream gear, in particular for speed reduction and torque increase, in particular a planetary gear, also in the handle section - or at least in its immediate vicinity or in the area of this - the housing is arranged ,
Preferably, the energy supply means is designed as an interchangeable electrical accumulator, which can be inserted into and removed from a receptacle of the mobile portable stapling device arranged at one end of the handle section of the housing. Due to this location of the arrangement of the accumulator, at most only a small torque is required for handling the stapling device, also because of the accumulator, whereby handling of the stapling device is made possible with little effort. In an advantageous further embodiment of the stapling device according to the invention, in the case of an arrangement of the accumulator provided on the handle section of the housing, it can be provided that at least one, preferably all, of the necessary electrical supply lines from the accumulator to the motor are arranged exclusively in the handle.
In a preferred embodiment of the invention, the electric motor arranged in the handle section of the housing can be designed as a brushless DC motor. The lack of wear-prone brushes in the motor not only leads to a longer service life and freedom from maintenance of the motor, the missing brushes also lead to a smaller size of the motor and thus to a possibility of designing the handle section solely from an ergonomic point of view and not according to the fact that the motor can be accommodated in the handle. The aspect of using a brushless DC motor as a drive for a portable, mobile stapling device for industrial use in the field of production and packaging, with which staples are ejected, can also have independent significance, independently of other aspects of the present invention, in particular, but not exclusively - Independent meaning in connection with a stapling device according to the preamble of claim 1.
A preferred measure can also contribute to an ergonomically favorable design of the stapling device, which provides that the axis of rotation of the electric motor with respect to an acceleration path of the expeller to expel a staple, an angle from a range of 60 ° to 120 °, is preferably chosen with an angle of at least approximately 90 °. It is further preferred that the two axes intersect. However, it can also be provided that the two axes are spatially offset from one another. In this case, the angle between the two axes is obtained by projecting one axis towards the other of the two axes.
It has also been shown to be advantageous if the energy supply means is arranged in the region of one end of the handle, preferably at the free end of the handle. If, in a particularly preferred embodiment of the invention, an exchangeable battery is selected as the energy supply means and can be arranged on the stapling device by means of a quick connection, for example a snap or snap connection, a receptacle for such batteries can be provided at the free end of the handle section of the housing. Electrical contact between the receptacle and the accumulator can be achieved by contact elements integrated in the receptacle. This results in a particularly short cabling between the energy supply means and the electric motor. This facilitates both the assembly of the stapler and possible repairs. Short cabling also leads to low electrical resistance in the cabling, which reduces electrical losses and increases the amount of energy in the accumulator that can be used to use stapling processes. In addition, the weight of an accumulator at the free end of the handle section leads to better balancing of the stapling device. The weight of the accumulator also acts as a counterweight to the mechanics of the ejection or ejection device of the stapling device.
According to a further aspect of the invention, the task of filling can also be achieved in a mobile portable stapling device according to the preamble of claim 8, which is provided for driving staples, in particular essentially U-shaped staples, into an object of the magazine. This object can be achieved by a fill level indicator or a fill level signal means, which is provided for signaling a supply of staples contained in the magazine. As a result, it is always recognizable or perceptible for a user whether the magazine is about to be emptied, an unforeseen vacancy of the magazine can be avoided. As a means for outputting an acoustic signal representing a certain fill level.
Brackets for filling a magazine are usually offered as bracket blocks that contain a certain number of brackets glued together. Depending on the number of clips and the size of the clips, these clip blocks therefore have a certain length. In a preferred embodiment of the invention, in addition to the fill level indicator, a marking can be provided on the magazine, which at least approximately
CH 713 984 A2 the length of the staple blocks suitable for the stapling device. As soon as the level indicator reaches the mark, there is enough space in the magazine so that a new clamp block can be filled into the magazine again. Depending on the length of the magazine and the length of the clip blocks, it can be provided that the marking, as seen from the magazine end, is approximately at the level of an integer multiple of the length of a clip block. If the level is reached by the fill level indicator, this signals that it is visually noticeable that a number of staple blocks can be filled into the magazine that corresponds to the integer multiple (N = 1,2, 3 etc.). The fill level indicator and the marking thus simplify the fact that the magazine can be completely replenished if possible when there is a shortage of clips in the magazine. As a result, the working cycles between two filling processes can be made as long as possible, whereby the number of unproductive filling processes can be reduced to a minimum.
The invention relates to a mobile portable stapling device for driving staples into an object, comprising a housing device with a main housing section and a handle section which extends away from the main housing section, an ejection device being arranged in the main housing section, by means of which a fastening means can be accelerated in each case is, in order to eject the fastening means from an outlet opening of the stapling device, a magazine device for receiving a supply of staples on the stapling device, a drive device for the ejection device, which is connectable or connected to an energy supply means, at least one release means of a release device with an actuatable release, by actuating it, at least one fastening means can be accelerated by means of the ejection device thereby set in motion and can be ejected from the outlet opening.
Portable staplers that use a fluid, particularly compressed air, to accelerate fasteners such as staples, nails, clamps, and the like, and to drive these fasteners into objects, are well known. Fastener drive tools of this type are used, for example, in the manufacture of furniture for attaching covers, for example leather covers, to furniture or for producing a bottom or lid closure of cardboard boxes. Depending on the field of application, staplers can differ in their basic construction. However, such pneumatic staplers generally always have a piston which can be moved in a cylinder between an upper and a lower dead center. A fastener drive member is disposed within the piston line of motion and is used to contact and eject the fasteners inserted into the fastener drive track from a magazine assembly. Pneumatic nail fastener driving tools are known which are provided with means for switching between two modes, in one mode each activation of the trigger results in a single shot of a fastener and in the other mode each activation of the trigger results in a plurality of successive ones Shooting leads as long as the trigger is activated and / or a mechanical contact of a microswitch in the area of a contact surface of the tacking nail device detects contact with a base.
Portable stapling devices are also known, which are additionally provided with pliers elements with which the legs of staples are bent after their entry into a cardboard box. Stapling devices of this type are used above all to produce closures on cardboard boxes, in particular for closing lid wings of the cardboard boxes. With this type of stapler, it is necessary to coordinate the ejection movement with the movement of the pliers elements in order to grasp the ejected two-legged clamp with the pliers elements when they have already penetrated the cardboard box and the two legs of the respective clamp in the direction of a base leg to bend the bracket. Such a portable portable stapler is known for example from EP 2 679 344 A2. In contrast to most other staplers currently on the market, the cardboard box stapler from EP 2 679 344 A2 is driven electrically and not pneumatically. For this purpose, the stapler from EP 2 679 344 A2 has a direct current electric motor which is fed by an accumulator and integrated in the portable portable stapler. The electric motor and its accumulator are accommodated in a housing part of the stapler, which is located between the handle of the stapler and the magazine for the staple supply, in the immediate vicinity of the magazine.
In this and other staplers, it can be felt to be disadvantageous that the staples cannot be set precisely at desired positions of objects.
The invention is therefore based on the object to provide a stapling device of the type mentioned, which has precise properties with respect to the possibilities to set staples precisely at predetermined positions.
This object is achieved in a stapling device of the type mentioned according to the invention by at least one light emitting means arranged in the housing device, which is arranged such that its emitted light contains optically perceptible position information on U-shaped staples that can be ejected by the stapling device. The invention thus essentially proposes to use light to convey at least information to the user about a position at which a staple, in particular an essentially U-shaped staple, can be ejected with the stapling device due to its current spatial orientation. With this knowledge, a user can align a stapling device according to the invention better than hitherto in such a way that a staple can also be used to insert a staple into an object at the intended position.
CH 713 984 A2 [0020] In a preferred embodiment of the invention, at least one light emitting means can be provided, with which a directed light beam can be emitted from the housing in the direction of an object. With a directed light beam, particularly precise position information can be displayed and conveyed. Light emitting means which emit directed light beams can be lasers, for example.
In a further preferred embodiment of the invention, the light beam can contain optically perceptible position information about a plane in which a clamp plane of ejectable clamps runs. A level of brackets can in particular be understood to mean a plane of symmetry of the U-shaped brackets which runs centrally through the base leg and parallel to the two side legs of the brackets. Such information can be particularly, but not exclusively, an advantage in connection with the processing of cardboard boxes, in which two foldable lid flaps are to be connected to one another by means of one or more clips to form a closure of the cardboard box. With such a light beam, the light beam of the stapling device can be aligned in alignment with a joint between the two cover wings, thereby ensuring an arrangement of the stapling device in a desired position in which one leg of the respective clip is placed in each of the two cover wings.
An alternative or additional measure can provide in a further preferred embodiment of the invention that the at least one light emitting means is arranged in the housing device and contains position information about a plane in which a clamp plane of ejectable clamps runs. Knowing the staple level, that is, the level within which the staple to be ejected and the ejection channel of the stapling device are located, can also contribute to the precise placement of staples in objects. It is particularly advantageous here if both the central plane and the clamp plane can be displayed by means of light emitting means of the stapling device.
Another aspect of the invention, which can also be independent of other aspects of the invention, provides several different light emitting means with which light in different colors can be emitted, or at least one light emitting means with which light can be emitted in different colors is, with the different colors in addition to the position information also state information on the stapling device can be visually perceived. For example, the one or more light emitting means, in addition to the position information about the ejection plane of the staples or another position information, can also signal with different colors for this respective position information whether the stapling device is ready for ejection of a staple. This information can be particularly important if - as is provided in preferred embodiments of the invention - at least one specific condition must be fulfilled for release of emissions. In preferred embodiments of the invention, this can be, for example, the detection of the presence of a user finger on the trigger and / or the presence of an object in the area of the footprint, which is the outlet opening for ejecting staples, or the contact of the footprint of the stapling device with an object.
In a preferred embodiment of the invention, the stapling device has only one light emitting means, which transmits a light beam directed forward by the device. The light beam should run in a plane that is at least substantially perpendicular to the base leg of the clip to be ejected, preferably centrally through the base leg. This preferred alignment of the light beam can also be defined as lying in a plane which is at least substantially perpendicular to the plane of the clamp, which the three legs of the respectively undeformed clamp to be ejected. This plane preferably runs parallel to the two free (still undeformed) legs and is at the same distance from each of them. This light beam can preferably be at least one laser light beam. In addition to a point laser, line lasers are of particular interest in this context, the emitted light of which appear as a line on an object. In this case, the light beam is a light plane emitted by the line laser. Such lasers are known per se and are offered by various manufacturers. In other embodiments, other light sources are also conceivable for this light beam, for example one or more LEDs.
In a further preferred embodiment of the invention, the stapling device has only at least one light emitting means which indicates the staple plane formed by the three legs of the staple to be ejected (as yet undeformed). The at least one light emitting means is preferably located and preferably shines in this bracket level and / or emits one or more light beams which are located in the bracket level. Such a light-emitting means is preferably provided on both sides of the housing on both sides of the outlet opening of the clamps. These light emitting means can preferably be LEDs. In other embodiments, other light sources are also conceivable for this at least one light emitting means, for example one or more lasers.
In a particularly preferred embodiment of the invention, the stapling device has both light-emitting means, namely at least one for signaling the position of the middle of the clip and at least one, preferably at least two, light-emitting means which indicate the position of the clip level in an optically perceptible manner.
In a further advantageous embodiment of the invention, which can also have independent meaning for generic stapling devices and thus also represents its own invention, regardless of other features and in connection with the features of the preamble of claim 1, and thus also represents its own invention, at least one laser can be used as a light emitter
CH 713 984 A2 can be provided, wherein setting means for the light emitting means are provided, with which a direction (emission direction) of the directional emitted light of the light emitting means can be set and changed. Since the most precise position information possible should be conveyed with the aligned light beam of the light emitting means, it is necessary for the laser to be mounted as precisely as possible in its intended orientation and position in the stapling device. However, due to manufacturing and / or assembly inaccuracies, there is a risk that the laser, in particular a line laser, will not assume the intended orientation and / or position in the holder. Such inaccuracies can be corrected and the laser aligned as desired using the setting means described here. In the case of a line laser, the course of the line imaged by the laser light on an object can hereby be changed and adjusted. In other embodiments of the invention, the measure described can also be provided for light-emitting means other than lasers, for example for an LED as light-emitting means.
[0028] In a preferred embodiment of the stapling device according to the invention, a commercially available laser, in particular a line laser, can be provided, which is arranged in a housing. The housing of the laser should be provided with an outer surface which is circular in cross section and arranged in a holder in which the housing can be rotated. An engagement element is preferably provided on the housing, the actuation of which enables the housing to be rotated in its holder. By rotating the laser, it can then experience a different orientation and thus a misalignment or arrangement can be at least partially corrected. The engaging element can preferably be accessible for actuation not only during assembly of the stapling device but also on the fully assembled and ready-to-use stapling device. This makes it possible to make a correction later and without dismantling the stapling device.
In an advantageous development of this possible embodiment of the invention, the engagement element can at least partially surround the outer surface and be accessible for manual actuation through a recess in the holder. In a further possible concretization, the engagement element can be elastically compressible and can be arranged in the preferably slot-shaped recess, at least slightly clamped. Such an engagement element can be, for example, an O-ring which is arranged under tension on the housing. The tension should be such that when an attempt is made to rotate the O-ring, there is no relative movement between the O-ring and the housing, but the housing is entrained when the O-ring moves. The at least slight clamping ensures that the light-emitting means cannot move unintentionally in its holder. An intentional operation is required to change its orientation or position. As a result, the O-ring can be actuated manually through the recess to perform a rotational movement, by which the housing of the light-emitting means is carried along and undergoes a change in its orientation or alignment. Due to the slight clamping effect with which the elastically deformable O-ring is arranged in the recess of the holder, the rotation takes place against an at least slight frictional force, which makes it possible for the light emitting means to be rotated by a very small angle of rotation and thus adjustable.
Yet another aspect according to the invention, which can also be independent of other aspects of the invention as an independent invention, can provide that the at least one trigger means has a detection means for detecting a body part arranged on the trigger, in particular a finger. The detection means for the detection of a body part arranged on the trigger can preferably be arranged in the actuatable trigger or on the housing, directly next to the actuatable trigger. With such a sensor on the release means, an additional safety measure can be implemented that a staple can only be ejected if an operator is in contact with the release means or at least a part of the body, such as a finger, is in the vicinity of the release means. This security measure can be provided either alone or as a fulfilled condition required in addition to other conditions. A suitable detection means for this can be, for example, a proximity sensor, a photodiode or a photoresistor.
[0031] Another condition for performing a stapling operation can be a detection of the presence of an object. For this purpose, at least one detection means for detecting the presence of an object below the contact area can be provided in the area of the contact area of the stapling device.
In a preferred embodiment of the invention, means can also be provided with which a detection signal of the detection means can be fed to a control of the stapling device, the control being set up in such a way that the detection signal is a prerequisite for the release of an output of a staple.
Finally, it has also been shown to be particularly advantageous if the detection signal of an existing body part can be used to switch on the at least one light emitting means. Thus, the at least one light emitting means can only be switched on when a user also provides for the stapling device to be used.
According to a further aspect of the invention, at least one of the measures according to the invention described above can also be provided in a mobile strapping device for strapping packaged goods with a plastic or metal band, with which a loop of such a band is tensioned and then attached to the tensioned loop a closure of the strap loop can be attached. In particular, at least one light emitting means can be provided on the housing of such a strapping device, which means indicates an insertion position and / or an end position of a strapping in the strapping device on the strapping device. Here too, the light emitting means can be arranged on the housing device of the strapping device in such a way that its emitted light
CH 713 984 A2 represents optically perceptible position information with which the operator is instructed to arrange the strap in a predetermined position in the strapping device.
The security against unwanted triggering of the stapling device can be further increased by a further preferred embodiment of the invention, in which the trigger can be actuated against the spring forces of at least two spring elements. It can be provided in an advantageous manner that when the trigger is actuated, it is initially only to be actuated against the spring force of the first spring and only in the course of further actuation of the trigger against the spring force of both spring elements. An output is preferably triggered after the spring force of the second spring element also acts on the trigger against the actuation of the trigger. Both spring elements are thus preferably in the path of movement of the trigger, but act on the respective trigger for the first time when the trigger has been actuated differently. Due to the suddenly increasing spring force due to the additional action of the second spring element, the user can be informed that a release is imminent. A user can thus better coordinate the output of a clip.
[0036] Further preferred embodiments of the invention result from the claims, the description and the drawing.
The invention relates to a mobile portable stapling device for driving staples into an object, comprising a housing device with a main housing section and a handle section which extends away from the main housing section, an ejection device being arranged in the main housing section, by means of which a fastening means can be accelerated in each case is, in order to eject the fastening means from an outlet opening of the stapling device, a magazine device for receiving a supply of staples as fastening means on the stapling device, a drive device for the ejection device, which can be or is connected to an energy supply means, a clinching device with which two legs of of a clip emerging from an outlet opening of the stapling device can be bent, at least one triggering means of a triggering device with an actuatable trigger, by actuating at least one loading fastening means can be accelerated by means of the ejection device thereby set in motion and can be ejected from the outlet opening.
Portable staplers that use a fluid, particularly compressed air, to accelerate fasteners such as staples, nails, clamps, and the like, and to drive these fasteners into objects are well known. Fastener drive tools of this type are used, for example, in the manufacture of furniture for attaching covers, for example leather covers, to furniture or for producing a bottom or lid closure of cardboard boxes. Depending on the field of application, staplers can differ in their basic construction. However, such pneumatic staplers generally always have a piston which can be moved in a cylinder between an upper and a lower dead center. A fastener drive member is disposed within the piston line of motion and is used to contact and eject the fasteners inserted into the fastener drive track from a magazine assembly. Pneumatic nail fastener driving tools are known which are provided with means for switching between two modes, in one mode each activation of the trigger results in a single shot of a fastener and in the other mode each activation of the trigger results in a plurality of successive ones Shooting leads as long as the trigger is activated and / or a mechanical contact of a microswitch in the area of a contact surface of the tacking nail device detects contact with a base.
Portable stapling devices are also known which are additionally provided with pliers elements with which the legs of staples are bent after they have entered a cardboard box. Stapling devices of this type are used above all to produce closures on cardboard boxes, in particular for closing lid wings of the cardboard boxes. With this type of stapler, it is necessary to coordinate the ejection movement with the movement of the pliers elements in order to grasp the ejected two-legged clips with the pliers elements when they have already penetrated the cardboard and the two legs of the respective clip in the direction of a base leg to bend the bracket. Such a portable portable stapler is known for example from EP 2679 344 A2. In contrast to most other staplers currently on the market, the cardboard box stapler from EP 2 679 344 A2 is driven electrically and not pneumatically. For this purpose, the stapler from EP 2 679 344 A2 has a direct current electric motor which is fed by an accumulator and integrated in the portable portable stapler. The electric motor and its accumulator are accommodated in a housing part of the stapler, which is located between the handle of the stapler and the magazine for the staple supply, in the immediate vicinity of the magazine.
In this previously known stapler can be seen as possibly disadvantageous that an actuation of the trigger is only possible after the device has been placed on an object and thus only a comparatively slow working with this stapler is possible.
The invention is therefore based on the object to provide a stapling device of the type mentioned, with which the working speed can be increased when staples are set.
This object is achieved in a generic stapling device according to the invention in that in the area of the contact surface of the stapling device, on which at least one clinching element of the clinching device for bending staples emerges from the contact area during a stapling process, at least one detection means for the property
CH 713 984 A2 detection of an object beneath the footprint is provided. This detection means and the detection signal provided by it can be used to carry out a stapling operation with a clip even without subsequent actuation of the trigger.
According to a second aspect of the invention, the object is also achieved in a generic stapling device in that means of the release device are provided with which at least two different operating modes of the stapling device can be set, in the first operating mode by a (one-time) actuation of the release means / Trigger only one stapling process can be triggered, in which only one staple can be ejected and the legs of which can be bent by means of the clinching device, and in a second operating mode with actuation of the triggering means, several successive stapling processes can be triggered, in each of which a staple can be ejected and its leg are bendable by means of the clinching device. As an alternative to the second operating mode mentioned or in addition as a third operating mode, such a mode can also be provided in a preferred embodiment of the invention, in which further stapling processes are carried out fully automatically in a predetermined specific or a changeable determinable interval. An ejection of brackets in this last-mentioned operating mode can take place, for example, as long as or in each case as long as a certain release condition for further automatic ejections of this one automatic ejection series is given after a first ejection. A possible condition can be, for example, that the stapling device is not lifted from the object but is pulled or guided for the automatic ejection of a series of clips over the respective object with constant contact with the object. It can thus be provided that the control of the stapling device stops a series of automatically ejecting staples as soon as the stapling device is lifted off the object. However, as long as the presence of the stapling device on an object is detected without the stapling device being lifted from the object in question, the automatic ejection series continues. Among other things, for this detection process, the stapling device can be provided with a release means which detects whether such a release condition is fulfilled.
Alternatively, it can also be provided that the presence of the stapling device on an object only has to be detected for the first ejection of such a series of ejections, which takes place automatically in an automatic mode, and all subsequent ejections then take place without such detection.
With regard to the number and / or time intervals of the outputs subsequent to the first output, these are preferably carried out in accordance with predetermined values stored in the control of the stapling device. With regard to the number of brackets that can be ejected in this mode, a maximum value of ejectable brackets can be specified, for example. The working speed can also be increased considerably with this. For example, in order to insert a series of staples into an object, in automatic mode it is only possible to pull the stapling device placed on an object over the object and the staples are then ejected in a predetermined or predeterminable time interval and driven into the object. In order that each user can adapt the stapling device to his work pace and his way of working, a teach-in mode can also be possible for the automatic mode in a further preferred embodiment of the invention. In this, the stapling device takes over and stores the time intervals in which a user manually actuates the respective release means or the release twice or more in succession. In said preferred possible embodiment of the automatic mode, brackets are then ejected at precisely these time intervals.
With the measure provided according to the invention, a faster method of operation can be used for stapling devices which are provided with a clinching device. a more comfortable and less tiring way of working can be achieved.
It can hereby also be used for stapling devices which are provided with a clinching device, a semi-automatic mode for carrying out several individual stapling processes carried out one after the other. In this operating mode of the semi-automatic sequence of several stapling processes, which is preferably provided as a second operating mode and can be adjusted and switched off, a plurality of stapling processes carried out in succession, including clinching processes taking place in each case, can be made possible by actuating a trigger element once, no manual one for each of these stapling processes Actuation of a trigger element by the operator is required. It is only necessary to actuate the trigger element once. In contrast to the automatic mode, it can be provided in the semi-automatic mode for the triggering of the clip ejections following the respective first clip ejection that these only occur if at least one other condition than the automatic mode is fulfilled and means are provided with which it is possible to detect whether the at least one condition for the semi-automatic mode is fulfilled. A possible condition can be, for example, that the stapling device must be lifted off the object after a staple ejection in order to carry out the semi-automatic ejection of a series of staples when the trigger is still operated. It can thus be provided that the control of the stapling device stops a series of semi-automatic staple ejections as soon as the stapling device is lifted from the object, but does not set down again on the object when the trigger is actuated. Among other things, the stapling device can be provided with a release means which detects whether such a release condition is fulfilled. The semi-automatic ejection of staples can also be stopped by the actuation, in particular pressing, of the trigger being ended.
In a preferred embodiment of the invention, a release means can be provided in addition to the triggering means, which in at least one of the two operating modes when a predetermined condition is met
CH 713 984 A2
Release signal for performing a stapling of the controller. In a particularly preferred embodiment of the invention, three possible operating modes are provided, namely a manual mode, a semi-automatic and an automatic mode, and in all three operating modes the release means for releasing each clip to be ejected can detect whether the next clip is released for ejection. Such a release means can in particular contribute to increasing security, so that a stapling operation can only be carried out if a security-relevant condition is met. The release means can thus comprise at least one detection means with which the presence of an object in the area of the contact area, in particular contact of the contact area with the object, can be detected. It can be provided that a stapling operation with a clip can only be released when an object is detected in the area of the contact area by means of a detection means. In this context, non-contact release means are particularly preferred, that is to say in particular non-contact detection means, which themselves do not require mechanical contact to detect the presence of an object in the area of the contact area.
The at least one detection means for determining an object on the contact surface, in particular a contact between the contact surface and the respective object, can in principle be based on different detection principles. In particular, optical detection means are possible, for example those which have a light transmitter and a light receiver, the object serving as a reflection surface of light emitted by the light transmitter which is to be detected by the light receiver. Mechanically operating detection means are also possible, for example microswitches. Other detection means can be, for example, light resistances, ultrasonic distance sensors, proximity sensors and other sensors which are able to determine the presence of an object.
A preferred development of the invention for this purpose can provide at least two detection means arranged at a distance from one another in the area of the contact area. For example, for objects that are not planar, such as curved objects, it may be sufficient that a release for a stapling operation already takes place when one of the two detection means detects the presence of an object, in particular contact with the object, below this detection means and a corresponding signal the control of the stapling device.
In addition to the same embodiment or in an alternative embodiment of the invention, it can also be provided that both of the at least two detection means must provide an enable signal so that a stapling process can take place. If one or more staples are to be driven into an object with an essentially flat surface in the area of the footprint and legs of the respective staple are to be bent, it can make a decisive contribution to increasing functional reliability if both detection devices have an object in the area of the respective one to enable a stapling process Must provide detection means. In this context, a particularly advantageous embodiment of the invention is when one of the two detection means is arranged on one of the two short side edges of the outlet opening. Such an embodiment can ensure that both legs - and not just one or no leg - of a clip penetrate into the respective object.
The at least one release means provided in addition to the actual triggering means, which is preferably designed as at least one detection means, has particular advantages in connection with the semi-automatic that is preferably adjustable according to the invention as a possible operating mode. With this detection device, it can be ensured in a possible embodiment of the invention that each of the stapling processes that actually takes place in the semi-automatic mode after an initial triggering of a semi-automatic cycle of possible stapling processes only takes place when the contact area is actually on or at least directly above an object , In addition, in the semi-automatic mode, the respectively determined detection result of an object present in the area of the contact area or a contact of the contact area with an object can be used to enable and execute the respective stapling process. It can preferably be provided here that for a, preferably for each, subsequent execution of a stapling operation in this cycle, first a non-presence of an object in the area of the contact area and subsequently an existence of an object in the area of the contact area must be detected.
In all conceivable embodiments of the present invention, it can be provided in a further preferred embodiment of the invention that a staple is ejected with a predetermined time delay after the respectively given at least one condition for releasing the ejection is fulfilled. In a particularly preferred embodiment, there can be two conditions, namely the detection of a body part at the trigger and the presence of an object below the outlet opening for the clips. If both objects are detected, they are released to eject a clamp. In this preferred embodiment, however, the ejection is triggered and carried out with a time delay, for example from a range from -ms to ..... ms. The time delay can offer the advantage of greater security that the stapling device is actually arranged on an object when a staple emerges from the exit opening of the stapling device. In the case of detection means, it can happen that, when approaching an object, an actually not yet existing contact is incorrectly detected as given, and thus a clip is ejected too early. By means of the described preferred measure, to provide a short delay for the ejection when the ejection conditions are reached, this behavior of detection means can be counteracted and the safety is nevertheless white
CH 713 984 A2 further possible high working speed can be increased. The length of the delay is preferably adjustable on the stapling device. Alternatively, a time-fixed, unchangeable delay can also be provided. The invention relates to a mobile, portable stapling device for driving staples into an object, comprising a housing device with a main housing section and a handle section which extends away from the main housing section, an ejection device being arranged in the main housing section, by means of which a fastening means can be accelerated in each case In order to eject the fastening means from an outlet opening of the stapling device, a magazine device for receiving a supply of staples on the stapling device, which can be detachably fastened in the region of an ejection channel to a carrier part of the stapling device by means of a quick-release fastener, is a drive device for the ejection device, which can is connectable or connected to an energy supply means, at least one trigger means of a trigger device with an actuatable trigger, by the actuation of which at least one fastening means by means of the ejection device set in motion can thereby be accelerated and ejected from the outlet opening;
Portable staplers that use a fluid, particularly compressed air, to accelerate fasteners such as staples, nails, clamps, and the like, and to drive these fasteners into objects are well known. Fastener drive tools of this type are used, for example, in the manufacture of furniture for attaching covers, for example leather covers, to furniture or for producing a bottom or lid closure of cardboard boxes. Depending on the field of application, staplers can differ in their basic construction. However, such pneumatic staplers generally always have a piston which can be moved in a cylinder between an upper and a lower dead center. A fastener drive member is disposed within the piston line of motion and is used to contact and eject the fasteners inserted into the fastener drive track from a magazine assembly. Pneumatic nail fastener driving tools are known which are provided with means for switching between two modes, in one mode each activation of the trigger results in a single shot of a fastener and in the other mode each activation of the trigger results in a plurality of successive ones Shooting leads as long as the trigger is activated and a mechanical contact of a microswitch in the area of a contact surface of the tacking nail device detects contact with a base.
In the prior art it can be seen as a disadvantage that display and control elements are not very user-friendly. The invention is therefore based on the object of improving the user-friendliness of the display and operating elements in a stapling device of the type mentioned at the outset.
This object is achieved in a stapling device of the type mentioned according to the invention by a membrane keyboard device comprising display and operating device, which has operating elements as membrane keyboard elements, the actuation of which settings of the stapling device and / or changes in state of the stapling device can be made. The invention thus proposes to preferably provide a central display and operating device on the stapling device, which comprises as many of the intended display and operating elements as possible and which are designed as a membrane keyboard.
In a preferred development of the stapling device according to the invention, it can be provided that the stapling device can be switched in a single ejection operating mode and in a semi-automatic operating mode, in which several stapling processes can be carried out in succession after only one actuation of the trigger. and operating device has display means for signaling the switched-on operating mode. In an advantageous embodiment of the invention, the display and operating device can have at least one membrane keyboard element for setting the operating mode.
As an alternative to the second operating mode mentioned or in addition as a third operating mode, such a mode can also be provided in a preferred embodiment of the invention, in which further stapling processes are carried out fully automatically in a predetermined specific or a variably determinable interval, as long as the stapling device is present is detected on an object. The working speed can also be increased considerably with this.
To increase the ergonomics and the functional reliability, it can be favorable if a display means is also provided on the membrane keyboard device for signaling a fault condition of the stapling device. If the display and operating device has a display means for displaying a state of charge of an accumulator of an electrically operated stapling device, it can be advantageous that the state of charge of the stapling device, including a fault state of the stapling device, can be signaled with the display means, in particular by another display mode of the display means, in particular by changing the color and / or by switching to a flashing mode.
In a further preferred embodiment of the invention, the stapling device can comprise at least one light-emitting means arranged in the housing device, which is arranged in such a way that its emitted light contains optically perceptible position information relating to U-shaped staples that can be ejected by the stapling device. This light-emitting means can preferably be switched ready for operation without it emitting light. The at least one light emitting means can preferably only be actually switched on after a further condition is met, for example that an operator has arranged his hand or his finger at a specific position of the stapling device. Detection can thus be carried out on or near the trigger, for example
CH 713 984 A2 tel can be provided for detecting the hand or a finger, for example a proximity sensor. A readiness for operation of the light emitting means, which leads to a switching on of the light emitting means without a further separate switching-on operation and the switching on of the light emitting means only depends on the fulfillment of at least one operating condition, can be signaled by a display means arranged on the display and operating device of the readiness for operation. Such display means can, for example, be a display means of the membrane keyboard device. It can also be a light emitting diode.
An ergonomically favorable operating position, in which an operator immediately notices warning or interference signals during operation of the stapling device and can thus perceive them, can be achieved in that the display and operating device on a side surface of the main body section, in particular on an inclined side surface is arranged.
The invention relates to a mobile portable stapling device for driving staples into an object, comprising a housing device with a main housing section and a handle section which extends away from the main housing section, an ejection device being arranged in the main housing section, by means of which a fastening means can be accelerated in each case In order to eject the fastening means from an outlet opening of the stapling device, a magazine device for receiving a supply of staples on the stapling device, which can be detachably fastened in the region of an ejection channel to a carrier part of the stapling device by means of a quick-release fastener, is a drive device for the ejection device, which can is connectable or connected to an energy supply means, at least one trigger means of a trigger device with an actuatable trigger, by the actuation of which at least one fastening means by means of the ejection device set in motion can thereby be accelerated and ejected from the outlet opening.
Portable staplers that use a fluid, particularly compressed air, to accelerate fasteners such as staples, nails, clamps, and the like, and to drive these fasteners into objects, are well known. Fastener drive tools of this type are used, for example, in the manufacture of furniture for attaching covers, for example leather covers, to furniture or for producing a bottom or lid closure of cardboard boxes. Depending on the field of application, staplers can differ in their basic construction. However, such pneumatic staplers generally always have a piston which can be moved in a cylinder between an upper and a lower dead center. A fastener drive member is disposed within the piston line of motion and is used to contact and eject the fasteners inserted into the fastener drive track from a magazine assembly.
Portable stapling devices are also known which are additionally provided with pliers elements with which the legs of staples are bent after they have entered a cardboard box. Stapling devices of this type are used above all to produce closures on cardboard boxes, in particular for closing lid wings of the cardboard boxes. With this type of stapling device, it is necessary to coordinate the ejection movement with the movement of the pliers elements in order to grasp the ejected U-shaped two-leg clamps with the pliers elements when they have already penetrated the cardboard and the two legs of the respective clamps in the direction to bend onto a base leg of the clip. Such a portable portable stapler is known for example from EP 2 679 344 A2. In contrast to most other staplers currently on the market, the cardboard box stapler from EP 2 679 344 A2 is driven electrically and not pneumatically. For this purpose, the stapler from EP 2 679 344 A2 has a direct current electric motor which is fed by an accumulator and integrated in the portable portable stapler. The electric motor and its accumulator are accommodated in a housing part of the stapler, which is located between the handle of the stapler and the magazine for the staple supply, in the immediate vicinity of the magazine. With this stapler, it cannot be satisfied that the magazine cannot be easily operated due to the housing part of the motor. In particular, when the stapler is operated, the housing part of the motor blocks a clear view of the magazine, for example to visually check the remaining amount of staples in the magazine. In addition, clamps jammed in the ejection channel can only be removed from the ejection channel in a time-consuming manner.
The invention is therefore based on the object of improving an industrial or commercial stapling device of the type mentioned in such a way that the magazine device can be removed and used more user-friendly, in particular in order to remove clamps jammed in the ejection channel as quickly as possible and the stapling device again to be ready for operation.
This object is achieved according to the invention in a stapling device of the type mentioned at the outset in that the quick-release fastener is provided with guide means which, when the magazine is inserted on the carrier part, successively converts the magazine into two different, non-parallel to one another, preferably at least essentially in each case straight lines, directions leads. The magazine can preferably also be removed from the stapling device only when the magazine is removed by moving the magazine along these two non-parallel longitudinal axes, but in the reverse order and in the opposite directions of movement. It is particularly advantageous here if only the movements along the two different axes or directions of movement are possible for removing and inserting the magazine. Since the movements for insertion and removal are clearly specified and also movements that can be carried out simply and quickly, the magazine can
CH 713 984 A2 can be quickly removed and used again quickly. The object is also achieved by the features of claim 15.
It can be particularly advantageous here if guide means are provided, by means of which the magazine is successively guided in two mutually perpendicular directions when the magazine is inserted. Such movements are particularly easy for a user to understand.
It can be particularly advantageous here if one of the directions of movement runs parallel or at least approximately parallel to the contact surface of the stapling device. In particular, if during the removal the movement parallel to the contact surface is the movement to be carried out first and during the second movement, it is also possible to carry it out with the stapling device itself, the magazine can be removed from an object in a working position without the object object being edited must be lifted off and removed.
In a further preferred embodiment of the invention, at least one of the two movements is limited by a stop. This is preferably the movement to be carried out first, as a result of which incorrect operation can be avoided. As a result, the operator has no difficulty in moving from the first to the second movement at the correct point.
It can also be advantageous if at least one swivel lever or quick-release lever of the quick-release fastener is provided, which can be swiveled about a swivel axis running perpendicular to the contact surface. In the area of both sides of the magazine, it should preferably be possible to swivel a swivel axis running perpendicular to the contact surface. This enables an ergonomically particularly inexpensive, yet functionally reliable quick fastener to be implemented.
A further improvement in functional reliability can also be made possible by the fact that the pivoting lever can be pretensioned or pretensioned with a spring element, the pivoting lever being pivotable about a pivoting axis against a spring force of the spring element and a latching lug of the pivoting lever being able to be lifted out of a latching position in order to remove the magazine ,
Preferably, the at least one pivot lever is arranged on a carrier part of the stapling device and interacts with a counter element of the magazine. A particularly favorable solution can provide that the counter element is a plate arranged on the magazine, which in the inserted state of the magazine delimits the ejection channel on one side of the ejection channel, preferably a magazine side of the ejection channel.
The functional reliability can be further increased by a preferred embodiment of the invention if the quick-release fastener has self-locking means which prevent the magazine from being removed without actuating a solvent provided for releasing the magazine. The self-locking should preferably increase the holding forces of the magazine in such an attempt or further increase a positive locking. One of several options for self-locking can be, for example, that when trying to remove the magazine without actuating the solvent, the magazine rotates a pivot lever - as a solvent for releasing the quick-release fastener - against a direction of release.

In Fig. 1, a portable electrically driven stapler 1 is shown as a stapling device, as is provided in the industrial or commercial area for driving fasteners, in particular staples, in documents. The electrical energy provided is used to drive out or eject staples. The housing has a main housing section 2 and a handle section 3, as will be discussed in more detail below. A removable and removable magazine device 4 is arranged on the main housing section 2, in which a supply of staples can be accommodated. An ejection mechanism 6 is arranged within the main housing section 2, which includes an ejector 8 driven by a motor 7, which on its acceleration path hits the foremost staple from the magazine 4, accelerates it and out of one
CH 713 984 A2
Ejection channel 9 and its outlet opening 10 ejects. The outlet opening 10 is located in the area of an essentially flat contact surface 11 with which the stapling device 1 is placed on the good or object in order to place a staple in the respective object in a motor-driven manner with the stapling device 1.
In the present case, the stapling device is provided for closing cardboard boxes. It therefore has two so-called clinchers 14 (FIG. 3), which are synchronized with the movements they execute with the movement of the ejector 8 and penetrate into the cardboard box during their movement, around the two legs of the respective staple in the direction of a base leg to bend the staple.
The housing can preferably be made of a castable or sprayable plastic and have two assembled housing halves. Each housing half thus has a part of the main housing section 2 and a part of the handle section 3.
The ejection mechanism 6 arranged in the main housing section 2 has a rotary element driven by the motor 7, which is provided with an eccentrically arranged cam. The cam is guided in a backdrop of a linear lifting element. The lifting element is guided in a straight line in such a way that it executes a linear movement between an upper and a lower dead center, in each of which a reversal of the direction of movement takes place. The link provided for the cam on the lifting element has a first link section running obliquely to the lifting axis and a second link section adjoining it at least substantially perpendicular to the lifting axis.
On the lifting element, a transmission rod is arranged with one of its ends, which is arranged with its other end on a guide element which is also guided in the lifting direction. The ejector is arranged at the lower end of the guide element and, together with the lifting element and the guide element, executes an oscillating movement between the top and bottom dead centers of their movement. With an end of the ejector facing away from the guide element and the end face provided here, the ejector is provided on its motor-driven path for contact with the foremost staple of the staple supply located in the ejection channel.
In addition, two clinchers 14 are each pivotably articulated on the guide element via a lever mechanism 28. Each of the clinchers 14 has at its free end a cutting edge 14a which, during an ejection stroke of the ejector 8, penetrates the object, here the cardboard, by the pivoting movement of the respective clincher 14 and there one of the two U-legs of the respective clamp 12 in Bends towards the base leg of the staple 12 to thereby fix the staple 12 against being easily pulled out of the cardboard box. Usually, a generic stapling device with its contact surface 11 is arranged on the cardboard box in such a way that one leg of the clip 12 penetrates into one of the two foldable wings of the cardboard box with which the cardboard box is to be closed. After the clinchers 14 have bent over the legs of the staple 12, the clinchers 14 are pivoted back out of the cardboard box during the upward stroke of the guide element and of the link element in the same way that they got into the cardboard box and to the underside of the two cardboard boxes. The downward and upward stroke movements of the link element are thus covered along the same rectilinear path, but in each case in the opposite direction of movement. The movements take place along a common longitudinal axis, which is arranged centrally in the guide channel of the link element.
[0083] According to the invention, the ejection mechanism 6 is driven by a motor, namely here by an electric motor. For this purpose, a brushless DC electric motor 7 is arranged in the handle section 3. Handle section 3 can be understood here to mean the section of the housing which is intended to be gripped by the hand of a user when the user inserts and guides the stapling device. This electric motor 7 is located, at least with one section with respect to its longitudinal extent, within the handle section 3 approximately at a point at which the handle section has a recessed grip 3a on its outside, which is provided for arranging the operating hand and fingers of the operating hand of the respective user and is determined. In the area of the recessed grip 3a, the user grips the handle section 3 and can thereby actuate a trigger 29 arranged in the region of the recessed grip 3a in an ergonomically advantageous manner with the index finger. The trigger 29 is thus located directly next to the motor 7 and the power board 25. By actuating the trigger 29, the ejection of a clamp can be started.
In the handle section 3 there is also a power electronics board 25 which is provided for controlling the motor 7 and for regulating the motor current. On the handle section 3, a receptacle for a removable and insertable rechargeable battery 26 is also provided in the region of its free end. In the exemplary embodiment, the power electronics board 25 is located between the battery 26 and the electric motor 7. Also, a required wiring 30 between the battery 26 and the power electronics board 25 and between the power electronics board 25 and the electric motor 7 is also located in the handle section 3 of the housing.
As can be seen in FIG. 1, the axis of rotation 7a of the electric motor is aligned at least approximately parallel to the contact surface 11 of the stapling device. As can also be seen in FIG. 1, the axis of rotation 7a of the electric motor is oriented at least approximately, preferably as precisely as possible, perpendicular to the longitudinal axis 13 of the guide or ejection channel for the staples, and the linear movement axis 13 of the lifting element. A planetary gear 27 is attached to the electric motor, with which the respective motor speed is reduced, i.e. changed slowly
CH 713 984 A2. The axis of rotation of the transmission output side of the planetary gear 27 connected to the axis of rotation 7a of the engine is aligned with the axis of rotation of the engine 7a. The crank of the ejector mechanism and then via the ejector mechanism 6 also the ejector 8 and the clincher 14 are driven with the drive output side drive movement. The motor axis of rotation 7a is approximately the same distance from the contact surface 11 as an initiation point for the motor rotational movement from the transmission 27 or electric motor 7 into the ejection mechanism 6.
The preferred embodiment of the invention is provided with a further aspect of the present invention, which may also have independent meaning that is independent of other aspects of the invention. This aspect relates to the trigger 29, which has a detection means 31 for detecting a body part arranged on the trigger, in particular a finger. This detection means 31 can be arranged either directly on the trigger 29 or else on the housing of the stapling device in the immediate vicinity of the trigger 29. The detection means for detecting a body part arranged on the trigger can be designed as a proximity sensor, as a photodiode or a photoresistor. By means of signal cables laid in the housing, a detection signal of the detection means can be fed to a control of the stapling device, the control being set up in such a way that the detection signal is a prerequisite for the release of an output of a staple.
Finally, the trigger 29 can preferably be actuated against the spring forces of at least two spring elements 17, 18. When the trigger 29 is actuated, this initially takes place only against the spring force of the first spring 17 and only in the course of further actuation of the trigger does the second spring 18 also act with its spring force against the trigger 29. As soon as the second spring 18 has an advanced actuation path of the trigger 29 a further pressing of the trigger 29 opposes their spring force as a compression spring, so the spring forces of both spring elements 17, 18 act and the trigger is then to be actuated against both spring elements 17, 18.
In the area of the contact surface 11 of the mobile portable stapling device there is a detection means 19, 20 on each side next to the exit opening 10, with which a presence of an object can be detected directly below the contact surface 11 and thus below the exit opening 10. These two detection means 19, 20 (sensors) are thus intended to determine whether the stapling device is arranged on an object into which a staple 12 can be released. It is preferably provided that both detection means 19, 20 must detect the object and each have to provide a corresponding signal to the control so that a clamp 12 can be released by the control for ejection. This can prevent staples from being ejected without the presence of a corresponding object and possibly injuring people. At least one detection means 19, 20 on each end face of the outlet opening 10 can also be used to detect whether the complete outlet opening 10 or not only part of it is located on an object. The at least two detection means 19, 20 are thus at a distance from one another which is greater than the length of the outlet opening 10. This also prevents staples from being ejected which are then located in an object with only one leg and thus not in are able to perform their intended function.
The two detection means 19, 20 are preferably designed as optical sensors. In other embodiments of the invention, however, mechanical sensors or sensors based on other functional principles can also be provided. In addition to other optical sensors, those can be suitable, for example, which emit light and detect a reflection of the emitted light. Such optical proximity switches have been offered in many different embodiments for a long time, which is why their construction will not be discussed further.
Finally, the figures also contain representations in which preferred embodiments of a stapling device according to the invention are shown, in which mechanical contact switches are provided as detection means 119, 120 in the contact area 11 instead of optical detection means. These detection means 119, 120 can be arranged at least substantially at the same locations on the contact surface 11 at which the optical detection means 19, 20 are also provided.
[0091] The preferred embodiment of the invention is provided with a further aspect of the present invention, which can also have independent meaning which is independent of other aspects of the invention. This aspect relates to the possibility of setting a semi-automatic mode and / or a fully automatic mode in addition to a single ejection mode of (only) one clamp each time the trigger 29 is actuated. This semi-automatic mode can be switched on and off on a display / operating device of the stapling device in each case by actuating a key, here, a key of a membrane keyboard 33. By switching on the semi-automatic mode, after a single actuation of the trigger 29, a stapling process is enabled as soon as certain conditions for the individual stapling processes that then take place automatically are met. Such conditions can in particular be that both the detection means 36 of the trigger 29 detect a finger and the detection means 19, 20 detect an object in the area of the outlet opening 10. If such detection signals from the detection means 19, 20, 36 are missing, it can be provided that there is already no release for a first bracket 12. However, if a first clip is released and thus output on the basis of such detection signals, the trigger does not have to be actuated again in this operating mode for the output of additional clips.
Conditions for triggering a stapling operation in the semi-automatic mode can thus be, for example, that it is determined by means of detection means that the contact area is on a surface of an object. To
CH 713 984 A2
Execution of the first stapling process in the semi-automatic mode can also be a condition for a subsequent stapling process of the same ejector in the semi-automatic mode that the detection means 19, 20 are used to detect a temporary distance of the contact area 11 from the object and then the presence of the object again in the area of the contact area 11. In other words, it must be detected that the stapler has been lifted off the object and put back on. It can also be provided that it is determined by means of a further detection means that an operator has placed a finger on the trigger, but without the operator having to actuate the trigger. In alternative other embodiments, however, it can also be provided that a series of staple ejections in semi-automatic mode can only take place when the trigger 29 is actuated continuously. It is possible that detection means, such as in particular optical proximity sensors, signal the presence of an object when the respective sensor is already in close proximity to the respective object, but there is still no contact between the stapling device and the object. In order to prevent staples from being ejected too early in the semi-automatic mode, i.e. at times when the stapling device with its contact surface 11 is not yet completely arranged on the object, a delay in the respective staple ejection can be provided after such detection signals. The time delay can either be stored in the control as a fixed, predetermined time value, or it can be adjustable by an operator on the stapling device, in particular it can be adjustable from a range from the time value. Possible time delays can be, for example, values from a range from 5 milliseconds to 350 milliseconds, but preferably from a range from 10 milliseconds to 200 milliseconds. In the exemplary embodiment, a value of 50 milliseconds is provided.
In addition to the manual operating mode, in which actuation of the trigger is required for each individual staple ejection, a (fully) automatic mode is also possible as an alternative or preferably in addition to the semi-automatic mode. In this preferably third operating mode of the stapling device, which can be set instead of the other two operating modes, after detection of the fulfillment of at least one release condition and after actuation of the trigger 29, staple ejections can take place as long as the trigger 29 is permanently actuated or pressed and the contact surface 11 is uninterrupted located on an object. In this way it is possible and provided, for example, that the stapling device 1 is pulled over an object and that a staple is ejected from a series of staple ejections at a specific time interval. As soon as either the trigger 29 is released and / or the stapler is lifted from the object, the control stops the ejection of further staples. Finally, in connection with the automatic mode, it can also be provided that the time interval (interval) can be changed from one clip ejection to the immediately following clip ejection. In a possible embodiment, this interval can be set on the stapling device 1 by a user as a value by means of an appropriate input. Alternatively or additionally, it can be provided in a further possible preferred embodiment that the interval is specified in a teach-in (learning) mode of the stapling device. For this purpose, the time interval in which a user releases two staples by means of the stapling device can be stored in an adjustable teach-in mode. This interval is then adopted for the automatic mode. In this way, the automatic mode can be adapted to the working method and working speed of a user. In the area of the contact surface 11, in the area of the two short side edges of the outlet opening 10 of the ejection channel 9, a detection means 36 is arranged on both sides for the detection of an object. These detection means 36 can be used to determine whether the stapling device with its contact surface 11 is on an object and thus a stapling process can be released. Detection signals of the detection means 36 are passed to the control of the stapling device and are taken into account there for the control of the stapling device. The detection means 36 can work according to different operating principles, for example as mechanical or as optical detection means.
In the figures, the stapling device with the magazine 37 inserted is shown at an angle from behind. In the magazine, a supply of staples 12 is inserted, which is pressed with a spring-loaded pusher 38 in the direction of the ejection channel 9 of the stapling device. The foremost of the U-shaped brackets 12 is thereby always located in the ejection channel 9, in which it is detected by the ejector 8 during its movement, accelerated and pressed out of the outlet opening 10.
In this illustration of the figures, a pivot lever 40 and its pivot axis 41 can be seen on each side of the magazine 37, the pivot lever 40 and their pivot axes 41 each belonging to a quick-release fastener with which the magazine can be detachably attached to the stapling device 1 and can also be removed by loosening the quick-release fastener. A first and a second pivot lever 40 are thus located on the opposite side of the magazine, both of which can be pivoted about their pivot axis 41 in each case. The two pivot axes 41 run parallel to one another and at least substantially perpendicular to the contact surface 11. Finally, the two pivot axes 41 are also aligned parallel to the longitudinal axis of the ejection channel 9.
As shown in the cross-sectional illustration of the figures, the main housing section of the stapling device has two guide bodies 42 for the magazine 37 which are arranged at a distance from one another. Each of the two guide bodies 42 is provided with guide elements for the magazine, which is approximately rectangular in cross section. On their walls, the guide bodies 42 are provided with guide elements 43 for moving the magazine 37 parallel to the contact surface 11 and with one or more stops to limit this movement. In the exemplary embodiment, these guide elements 43 are recesses running parallel to the contact surface 11, here slots
CH 713 984 A2-like recesses, in the guide bodies. In the exemplary embodiment, the ends of the slot-like recesses serve as stops 43a.
In the exemplary embodiment, the slot-like recesses merge into rectangular recesses in the walls of the guide body 44. The also rectangular recesses 44 serve as guide elements for a clearly guided relative movement between the magazine 37 and the housing of the stapling device. Upper end wall boundaries 44a of the recesses 44 represent the stops for the movement guidance through the recesses 44 in the direction perpendicular to the contact surface. Seen from the open rectangular shape of the recess 44, the closure in the area of the upper end wall boundary for each of the two essentially Rectangular recesses 44 each the slot extending parallel to the contact surface 11 and in the direction of the ejection channel 9 as a guide element 43. In the preferred exemplary embodiment described here only by way of example, each of the two guide bodies therefore has two identical guide elements 43, 44 arranged next to one another.
The magazine 37 is provided in the region of its side walls 46 on the ejection channel side with two tabs 47 arranged one behind the other at a distance. The tabs 47 protrude perpendicularly from the outer surfaces of the side walls 46 and, in the case of a magazine 37 inserted into the stapling device 1, have an essentially parallel orientation to the contact surface 11. The tabs 47 are spaced from one another and dimensioned such that they are arranged in the recesses of the guide elements 43, 44 of the guide bodies and can be moved there along the respective longitudinal extension of the recesses - and only along these longitudinal extensions. In order to attach a magazine 37 to the stapling device 1, the tabs 47 are inserted from the lower open side of the guide elements 44, so that the tabs 47 in the guide elements are moved parallel to the contact surface 11 until the respective tab 47 reaches the upper end face (stop) the respective recess of the guide element 44 is reached. This direction of movement is oriented perpendicular to the contact surface 11. The respective tab 47 can now be displaced parallel to the contact surface 11 in the respective slot-like recess of the respective guide element 43 until the tabs 47 each reach their stop 43a at the same time. The slots of the guide elements 43 and a thickness of the tabs 47 are dimensioned such that the tabs 47 are inserted into the respective slot of the guide elements 43 after reaching their stop 44a in the respective guide element 44 and can thereby execute a movement essentially parallel to the contact surface. When a magazine 37 is inserted, the first movement of the magazine 37, or of its tabs 47, in the recesses of the guide elements 44 and the second movement of the tabs 47 in the slots of the guide elements 43 are thus oriented perpendicular to one another. To remove the magazine from the stapling device 1, the slots are guided out of the guide elements 43, 44 in the opposite direction of movement, but along the same path. It is possible both when inserting and removing a magazine 37 to guide the stapling device 1 along the path described instead of the magazine 37. Only the corresponding relative movements between the magazine 37 and the guide bodies 42 of the stapling device 1 are decisive.
In each of the two guide bodies 42 one of the pivot axes 41 is guided on both sides in the region of the magazine 37 through the respective guide body 42 and a spring element 49, preferably designed as a compression spring, is supported and arranged on the guide body 42. The respective pivot axis 41 is arranged at a distance from the spring element 49 (compression spring) and has a smaller distance from the ejection channel 9 than the respective spring element 49 on the same magazine side. Each of the swivel axes 41 runs at least substantially perpendicular to the contact surface 11 of the stapling device and at least substantially parallel to the longitudinal axis of the ejection channel 9. The swivel levers 40 which can be swiveled about their respective swivel axis 41 can thus execute swivel movements about this axis which are essentially in a swivel plane , which run parallel to the contact surface 11. The respective pivot axis 41 is also passed through one of the pivot levers 40.
The respective guide body 42 is located between the magazine 37 and the pivot lever 40 belonging to this magazine side. On the outside, each of the pivot levers 40 has a shoulder 50. The shoulder 50 is intended to bear against a surface of a carrier body of the stapling device 1 and thus serves to limit the insertion depth of the magazine 37 into the stapling device. In addition, each of the two swivel levers 40 is curved with its end on the ejection channel side in the direction of the magazine 37 and is provided with a profiled end face 45 (FIGS. 7-12).
The stapling device 1 has, in the region of its magazine-side opening, which is also in the region of the ejection channel 9, a rear plate 51 which, when the magazine 37 is inserted, delimits the ejection channel 9 on the magazine side and is part of the magazine 37. The rear plate 51 extends on both sides beyond the rail, the magazine 37, in which clips 12 are stored. Side surfaces of the rear plate 51 are located approximately at the level of the ends of the pivot levers 40 on the outlet channel side. The end faces 45 of the pivot lever ends are each provided with two partial surfaces 40a, 40b enclosing an obtuse angle, which interact with the respective side surface 51a of the rear plate 51.
In order to loosen and remove the magazine 37 fastened in the stapling device 1, for example due to a jam in the clamp, or to refill the magazine 37, the two pivot levers 40 must first be actuated about their respective pivot axis 41 and against the spring force of the spring elements 49 become. When a magazine 37 is inserted and locked in place on the quick-release fastener, the rear sections 40c of the swivel lever 40 are also located
CH 713 984 A2
Distance to the respective guide body 42. These pivot lever sections 40c are pressed away by the spring element 49 from the guide body 42 in the form of a torque about the pivot axis 41. A swiveling movement of the swivel lever 40 caused thereby is limited by a stop of the shoulder 50 of the swivel lever 40 on the carrier body or on the housing of the stapling device. An actuation of the pivot lever 40 now initially leads to a pivoting movement about the pivot axis 41 against the spring force, so that the rear portions 40c of the pivot lever 40 come into contact with the guide body 42, as shown in FIGS. 7, 8, 9 , The profiled end faces of the front ends of the pivot levers 40 are in this case of their identical locking positions on the rear plate 51, in which the two angled partial surfaces 40a, 40b of the profiled end faces of the pivot levers 40 bear against an edge region of the end face of the rear plate 51 rear plate 51 lifted off. The magazine 37 is hereby released for a pull-out from the guide (guide elements 43, 44), the quick release is thus released.
[0106] However, as long as the respective end face of the pivot lever 40 abuts against the end face 51a of the rear plate 51 and the quick-release fastener is not released manually, the quick-release fastener is locked in a self-locking manner. A pull on the magazine 37 has the result that, due to the geometry of the front ends of the pivot levers 40, the rear plate 51 tends to pivot both pivot levers 40 about their pivot axes 41 against their direction of rotation when the quick-release fastener is released. This leads to an increase in holding forces which are exerted by the pivoting levers 40 on the carrier or housing side on the rear plate 51 on the magazine side.
After the quick release is released as described, the magazine 37 can be distanced from the housing with a movement running parallel to the contact surface 11. The direction of this movement is predetermined by the slots of the guide elements 43 and the tabs 47 guided therein. The movement is stopped as soon as the tabs 47 abut against side boundary walls of the recesses in the guide elements 44. In this position, all tabs 47 with their entire longitudinal extensions are located within the recesses of the guide elements 44, specifically at their upper ends. The magazine 37 can be completely removed from the stapling device by moving the tabs 47 within the recesses of the guide elements 44 toward the open lower end of the recesses or, alternatively, moving the recesses along the tabs 47. A simple and safe way of removing the magazine 37 can thus be to place the stapling device 1 with its contact surface 11 and the underside of the magazine 37 lying on a surface and to actuate the pivoting levers 40, which can also be referred to as quick-release levers. The magazine 37 is then pushed parallel to the contact surface 11 in a first direction until the tabs 47 stop. The stapler can then be raised perpendicular to the contact surface 11 relative to the magazine until the recesses in the guide elements 44 are removed from the tabs. The magazine 37 is now separated from the stapling device 1 and is freely accessible.
To insert the magazine 37 into the stapling device 1, the aforementioned movements between the magazine 37 and the stapling device 1 can then be carried out in the reverse order and in the opposite direction of movement (FIGS. 10, 11, 12). The magazine 37 can be attached with its tabs 47 from below to the recesses in the guide elements 44. With a movement of the magazine 37 perpendicular to the contact surface 11, the tabs 47 can be inserted into the recess and guided up to the first stop. The magazine 37 can then be moved perpendicular to the first movement in the direction of the ejection channel 9. The rear plate 51 arranged on the magazine 37 comes into contact with the ejection channel-side ends of the pivot levers 40 and pivots them against the spring force of the spring elements 49 about their respective pivot axis 41. The rear plate 51 can thereby pass through the pivoted pivot levers 40, whereupon those caused by the spring elements swing the loaded pivot lever 40 back into its locking position in the opposite pivoting direction. Due to the acting spring force, the swivel levers 40 snap back, which can serve as an indication for the operator that the magazine 37 is correctly arranged in its end position. As can be seen in the enlarged representation of one of the figures, one of the partial surfaces 40a of the front end face of the respective pivot lever 40 comes in front of the rear plate 51 and locks it against a pull-out of the magazine 37. The other partial surface 40b of the front end face lies on the other hand against the side surface (end face) 51 a of the rear plate 51 and is thereby prevented from further movement about the pivot axis. The pivot lever 40 thus remain in this position. In addition to the magazine 37, the rear plate 51 is thus also arranged in the intended position on the stapler 1 in which it limits the ejection channel 9 on the magazine side.
In order to increase the security that the stapling device cannot be triggered if no magazine is inserted in the stapling device, the stapling device has a blocking device which is provided with a movable blocking means. The blocking means can be pivoted into the movement path of the ejector 8, so that the ejector 8 cannot carry out a lifting movement. The blocking means can be arranged in two end positions, the blocking means being in the first end position outside the movement path of the ejector 8 and thus releasing the ejector for its lifting movement for ejecting a clip. In the second end position, however, the blocking means is in the movement path and thus blocks the ejector.
In the illustrated preferred embodiment of the invention, the blocking means is designed as a pivotable pawl 55 which is arranged on a shaft 56 and is pivotable about the longitudinal axis of the shaft 56. The shaft 56 and its pivot axis are aligned perpendicular to the stroke movement of the ejector 8 and parallel to the base leg 12a of the staples 12 arranged in the magazine. The pawl 55 has two legs 55a,
CH 713 984 A2
55b, one leg 55a is located on one side of the shaft 56, the other leg 55b is located on the opposite side of the shaft. The pawl 55 has at its lower end near the outlet opening 10 on the leg 55a a driving lug 57. In addition, a compression spring 58 presses against the other leg 55b, which thereby tends to press the leg 55b in the direction of the ejector. If no other force acts against the pawl 55, the force of the compression spring pivots the pawl 55 with its leg 55b into a groove 8a of the ejector 8. In this end position, the leg 55b of the pawl 55 blocks the ejector against movement in the ejection channel 9.
By inserting a magazine 37 into the stapling device, a component 59 of the magazine pushes against the leg 55a of the pawl shortly before reaching the end position of the magazine in the stapling device 1. When the magazine 37 moves parallel to its longitudinal extent, the component of the magazine detects the catch nose 57 of the pawl 55 and pivots the pawl 55 against the spring force of the compression spring, so that the leg 55b comes out of the groove of the ejector 8 and thus also out of the movement path the pusher 8 is pivoted. When the magazine 37 reaches its end position, it holds the pawl 55 in abutment against the driving lug 57 in a second end position, in which the pawl 55, in the illustration of FIGS. 13, 14, is oriented essentially vertically and parallel to the ejection direction of the clamps. The pawl 55 is in this second end position outside the ejection channel 9 and thus releases the ejector for an ejection movement. When the magazine 37 is removed again, it then releases the driver nose 57 and thus the pawl 55 again. The pawl 55 can thereby be moved back into its end position during the removal movement due to the force of the compression spring 58, in which it blocks the ejector 8.
As can be seen from FIGS. 17, 18, the magazine is provided with a fill level indicator 60. For this purpose, a marking 61 is attached to one or more fixed parts of the magazine 37, which signals the degree of the supply filling on clips in the magazine. The markings can, for example, have optically perceptible differences along the supply or stacking direction of the staples in the magazine, which stand for a different degree of filling or symbolize such a degree. The optical differences can be, for example, color-coded partial markings 61a, 61b, 61c. In particular, a minimum fill level marking, from which the magazine is to be refilled, can be marked with a signal color, such as red, in particular a signal red. Of course, other types of marking are also conceivable and possible, for example different geometric shapes. An acoustic signal, either in addition or alone, when a minimum fill level is reached can also be provided.
The magazine 37 also has a display or indication means 63 which moves together with the staple stack which is reduced during the work, which signals the respective current fill level of the magazine 37 with staples 12 at the markings 61. A particularly favorable solution can provide that a spring-loaded slide 64, with which the stack of clips 12 arranged in the magazine 37 is pressed in the direction of the ejection channel 9 of the stapling device 1, for displaying or indicating the fill level on the basis of the one or more markings 61 serves. A structurally simple embodiment can provide, for example, that an end face of the slide 64, with which the slide rests against the staple stack, indicates or represents the respective fill level at the markings. The solution implemented in the exemplary embodiment provides an arrow 62 arranged on the slide and directed at the markings as an indication means 63. The arrow can, for example, be arranged on a grip part of the slide 64, with which the slide can also be moved manually in the magazine 37, in particular retracted to hold clips.
[0114] The figures show preferred exemplary embodiments of further aspects according to the invention. 20-28, for example, the stapling device 1 is shown with its housing, the stapling device 1 having a light-emitting means 70 that emits from the housing. The light emitting means 70 is located on the front side 1a of the housing. In the exemplary embodiment, this light emitting means 70 is a line laser, which is arranged in the housing above the ejection channel 9. The laser 70 radiates forward from a housing opening 71, in front of the stapling device 1. As can be seen in FIGS. 20, 21, the line laser emits a light plane 72 directed towards the respective object as a light beam 72. This light plane can be perceived on the object as a projected, straight line 72a. Since the laser 70 preferably radiates out of the housing opening 71 in the housing division plane that is as precisely as possible central, which is also arranged centrally in relation to the ejection channel 9 and centrally to the base leg 12a of the brackets, in particular the brackets 12 located in the ejection channel 9, gives the projected Line 72a the middle of the base legs 12a of the clips 12 to be ejected again. So that a user of the stapling device can place the staples 12 as precisely as possible, he can orientate himself on the line 72a projected onto the respective object, which - with regard to the longitudinal extension of the base leg 12a - indicates the center of the base leg 12a, should a staple ejection occur in this position of the stapling device occur. The line laser 70 thus has the function of a positioning aid and the user can orientate himself on the projected line 72a in order to achieve a specific orientation of the stapling device 1 and thus a specific orientation of a clip 12 provided for ejection.
It is further preferred that the light emitting means 70 embodied here as a line laser, like any other light emitting means conceivable as a positioning aid, can be switched on and off, for example via a switch or a button on the stapling device 1 particularly preferred embodiment of an invented
CH 713 984 A2 according to the stapling device according to the invention that an automatic switching on and off of the respective light emitting means is provided upon presentation of certain conditions, in particular can be switched on and off as a function. An automatic switch-on can take place, for example, when an operator touches the trigger 29 or a finger approaches it and this is detected. Additionally or alternatively, it can also be provided that the at least one detection means 19, 20 in the area of the contact area 11 must detect the presence of an object directly below the contact area 11, so that the respective light emitting means is automatically switched on to display optically perceptible position information relating to a clamp position.
The line laser 70 has a housing 74 which is circular in cross section and which is arranged in a holder 75 within the housing of the stapling device 1. For this purpose, the holder 75 has a receptacle 76, likewise circular in cross section, in which the line laser 70 is arranged and mounted. A longitudinal axis of the circular receptacle is directed obliquely downwards onto the respective object and at a distance from the stapling device 1. An elastically stretched O-ring 77 is arranged on the outer surface 74a of the housing 74 of the line laser 70. A section of the O-ring 77 is located in a recess 78 in the wall of the holder 75, so that this section of the O-ring 77 is accessible for access. By rotating the O-ring 77 through the recess 78, it is possible to change the rotary position of the line laser 70 in its holder 75. The O-ring 77, which is tightly arranged on the housing 74 of the laser 70, takes the laser 70 with it during this actuation, so that the laser 70 rotates in the holder 75. The slight clamping of the O-ring 77 in the holder 75, which is also present, is overcome when it is actuated and allows very small rotation angles of the laser 70 to be carried out and adjusted in the holder 75.
By rotating the laser 70, the orientation of the line 72a projected by it onto an object can be changed. Any deviation of the actual rotational position from the intended target position, which may be generated when the laser 70 is mounted in the holder 75, can result in the projected (light) line 72a having an at least slightly oblique course with respect to the base leg 12a of the respective bracket 12. By means of the O-ring and the recess 78 in the holder 75, such misalignments can be corrected easily and quickly and the laser can be aligned precisely with its desired position. Such a correction can also be carried out simply and quickly even after the stapling device has been assembled and delivered, should such a misalignment become apparent or arise only in use.
[0118] In the drawings, two further light emitting means 80 are shown, which also indicate position information about a staple 12 to be ejected. These two light emitting means can also be designed as a laser, in particular as a line laser. The two identically constructed light emitting means 80 are located on one side of the stapling device under the housing and essentially above the ejection channel. The respective line laser 80 also radiates its light from a respective housing opening obliquely downwards onto the respective object and can in turn be optically perceived there as a straight, projected line. The construction and arrangement of the two line lasers 80 and their arrangement in a holder including an adjustability can be provided in accordance with the solution of the laser 70.
Each of the two lasers 80 emit a light plane on different sides of the stapling device, each of which projects a line 80a on the respective object, each of which is aligned perpendicular to line 70a and in alignment with a center line of the ejection channel. The lines 80a also run in alignment with the base leg 12a of a clip 12 to be ejected. Furthermore, the lines 80a projected by the lasers 80 on both sides of the stapling device are aligned with one another. The two light emitting means thus signal the longitudinal profile of a base leg 12a of a clip to be ejected or the plane in which the three legs of a clip 12 to be ejected are located. The two light emitting means 80 which interact with one another thus also serve as positioning aids in order to eject a clip in a predeterminable position or to place it in an object.
In an alternative embodiment of the invention, the light emitting means 70, 80 can also be designed with light sources other than lasers. In other embodiments, in particular, lasers can be replaced by one or more LEDs 86. In particular for LEDs as light emitting means 80, a type of light well 85 can be formed on the housing, which preferably has a transparent, at least partially transparent, cover 84. The respective light well 85 preferably runs in the plane, the position of which the respective light emitting means is intended to indicate. If the stapling device on both sides of the stapling device 1 has a light shaft with at least one illuminated LED that can be switched on and off, each of the two light shafts 85 should be located within the clamp plane formed by the three legs of the clamp to be ejected.
[0121] In a preferred development of the stapling device 1 according to the invention, one or more light emitting means can also be provided in a light shaft, in particular also those which can light up in different colors. Alternatively, two or more light emitting means can be provided in a light shaft, each of which shines in only one but in non-identical colors. Different colors can also be generated by lasers as light emitters. With such embodiments, it is possible, in addition to position information, to signal one or more further operating or status information, for example whether the stapling device 1 is ready for use, and / or whether there is a fault and / or in which mode the stapling device is and / or whether the detection means of the trigger 29 has detected a finger on the trigger 29. Instead of or in addition to below
CH 713 984 A2 different colors can also be provided for optically perceptible information transfer, flashing signals of the light emitting means or changing light emissions of the respective light emitting means in another way.
[0122] The figures also show the display / operating device of the stapling device as a membrane keyboard 33. In the preferred exemplary embodiment, the membrane keyboard is arranged on an inclined side surface of the main housing section 2 of the stapling device 1. This membrane keyboard 33 can have keys for various functions that can be set or called up. In particular, the membrane keyboard can be provided with one or more keys for setting the operating modes. Likewise, the membrane keyboard 33 can be provided with optically perceptible display means in order to optically perceivably set functions, values, malfunctions, state of charge of the accumulator and / or operating modes. Such display means can be lamps integrated in the membrane keyboard and / or alphanumeric displays. If necessary, illuminants and / or alphanumeric displays can also be integrated in keys on the membrane keyboard. The illuminants and / or the at least one alphanumeric display can optionally also present information in different and changing colors in an optically perceptible manner, just as a flashing mode is possible for them. This can be used to indicate particularly important information, in particular by means of warning colors, such as red.
