The invention relates to a machine for producing a composite cup of composite material, namely an outer shell and an inner cup, and a method for producing such a combination cup.
From WO2011 / 009615 A2 a generic machine and a method for producing a combi-cup from an outer shell or a sleeve and an inner cup has become known. The machine comprises a plurality of first holding devices and a plurality of second holding devices, wherein the two holding devices are respectively arranged on first and second holding device carriers. In the area of the first holding devices, at least one work station is arranged for executing at least one of the steps: providing a development for forming the outer casing, winding the unwinding on or into a first holding device, pressing and / or gluing ends of the wound onto or into a first holding device Settling to form a seam area. By means of a transfer station, the transfer of a finished outer shell from a first holding device to a second holding device takes place. In the region of the second holding devices, at least one second work station is arranged to carry out at least one of the steps: pressing the outer casing into or the inner cup onto a second holding device, inserting a finished inner cup into the finished outer casing, pressing the finished inner cup into the finished outer casing, checking the make cups, sort out defective cups, remove the finished cup from the second holder. Furthermore, the machine may also comprise a plurality of third holding devices, which are arranged on a third rotatably mounted star or wheel-like holding device carrier. In the area of the third holding devices, at least one third workstation is arranged to carry out at least one of the steps: singulating the finished inner cup from a stack, applying adhesive to the outside of the inner cup. Another transfer station is used to transfer a finished inner cup of a third holding device to a second holding device.
EP 1 990 184 A1 describes a device for producing a conical sleeve for cups and / or a conical paper cup. Here, the device comprises a machine frame and at least two rotatably connected to the machine frame and cyclically driven star wheels, a first star wheel having a plurality of conical mandrels, on each of which a sleeve of a flat blank is malleable. The star wheels are arranged lying in a plane and arranged on horizontally oriented drive shafts on a vertical wall of the machine frame. In this case, in the region of the first star wheel, the shaping of the sleeve takes place starting from a planar blank. Thus, flat blanks are fed to a first processing station, this being done by a separating device, starting from a blank stack. The flat blank is wound in the subsequent processing stations around the conical mandrel, sealed on its longitudinal side and then forms a conical sleeve. In the area of a transfer station, the finished sleeve is transferred to a hollow mandrel of the second star wheel. This hollow mandrel receives the sleeve from the outside. At the moment of transfer, the hollow mandrel in the processing station is aligned exactly coaxially with the conical mandrel of the processing station in the region of the first starwheel. Thus, the sleeve can be transferred in a linear motion directly from the first star wheel to the second star wheel. In the area of the second star wheel, after the transfer of the sleeve from a third star wheel, a prefabricated paper cup is fed to a prefabricated plastic cup and inserted into the sleeve located in the hollow mandrel. In a subsequent processing station, the inner cup inserted into the sleeve is connected to the sleeve in a separate step. This can be done for example by pressing or gluing. After this connection process, the finished cup can be removed.
From DE 195 17 394 A1 a method and a machine for producing a thermally insulated cup container has become known, which has a corrugated outer shell and an inner cup, which are separately formed and assembled. The outer jacket is first processed from a smooth blank to a smooth and frusto-conical blank and then corrugated. In a machine for making cup containers, the embossing of the outer shell and the assembly of the same with the inner cup can take place in one and the same shaped bushing, of which a plurality are arranged on a rotary star. In this case, an adhesive is applied in the region of a preparation station on the blank and then transferred to the mandrel, which is arranged on a rotary star. The application of the adhesive takes place with a wheel-shaped gluing unit, wherein the orders are made in a parallel direction with respect to the conveying direction of the respective blank. After forming the sleeve, the transfer is made to a hollow shape of another rotary star, in which the embossing of the outer shell takes place. In a next station glue is applied to insert the inner cup in the next prepared workstation in the thus prepared and already formed sleeve. In a subsequent fixing and cooling station, the final connection between the inner cup and the corrugated outer shell takes place. In the last station, the removal of the finished container takes place.
No. 6,663,926 B1 describes a heat-insulating container which comprises a cup-shaped inner container and a conical outer casing surrounding it. In this case, the feeds of the blanks via its own feeding device, which is formed of parallel juxtaposed conveyor belts with driver elements. In this preparation station, the adhesive is applied by means of an adhesive applicator roll on one end of the blank. Again, in turn, the orders of the adhesive in a parallel direction with respect to the conveying direction of the respective blank. This prepared blank is transferred to a star wheel with a vertically oriented axis of rotation. On the star wheel frustoconical mandrels are arranged, on which the shaping of the blank takes place towards the shell. The shell is shaped by means of pincer-like gripping arms which wind the flat blank around the frustum-shaped mandrel and thus form the shell or a cuff.
Disposable cups are nowadays indispensable, usually to transport liquid, pasty or even powdery substances from a production site or delivery point to the consumer and to enable the latter to consume the cup contents. For example, producers of yoghurt, ready-to-serve meals and beverages may be considered as production facilities. As dispensaries, for example, restaurants, food stalls or coffee houses are conceivable that pass the cup content usually unlocked or unsealed.
Object of the present invention was to improve the known from the prior art systems or machines in terms of throughput and thus to increase the number of joined cups per unit time. Furthermore, the service life of the equipment or machines should be improved.
This object is achieved by an apparatus and a method according to the claims.
The machine for producing a cup made of composite material, namely an outer shell and an inner cup, comprises: a plurality of first holding devices, which are arranged on a first rotatably mounted star- or wheel-like holding device carrier, a plurality of second holding devices, which on a second rotatably mounted star or at least one arranged in the region of the first holding devices first workstation for performing at least one of the steps: providing a development to form the outer shell, winding the settlement on or in a first holding device, pressing and / or bonding ends of the on or in a first holding device wound settlement to form a seam region, a transfer station for transferring a finished outer shell of a first holding device to a second holding device and at least one in the region of the second Haltevorri second working station for carrying out at least one of the steps: resetting the outer casing in or of the inner cup to a second holding device, inserting and / or pressing a finished inner cup into the finished outer casing or pressing a finished outer casing onto the finished inner cup, checking the finished cup, Sort out defective cups, remove the finished cup from the second holder.
However, the object of the invention can also be achieved with a method for producing a cup made of composite material, namely from an outer shell and an inner cup by means of the following steps: performing at least one of the steps: providing a development of the outer shell, winding the settlement on or in one first holding device, pressing and / or gluing ends of the winding wound on or in a first holding device to form a seam region, in at least one arranged in the region of a first holding device first workstation, wherein the first holding device on a first rotatably mounted star or wheel-like holding device carrier - Passing a finished outer shell from a first holding device to a second holding device in the region of a transfer station, wherein the second holding device on a second rotatably mounted star- or wheel-like holding device carrier - Performing at least one of the steps: Resuming the outer shell in or the inner cup on a second holder, inserting and / or pressing a finished inner cup in the finished outer shell or pressing a finished outer shell on the finished inner cup, control of the finished cup, sorting of defective cups, removing the finished cup from the second holding device in at least one arranged in the second holding device second workstation.
The advantage achieved thereby is that in this machine and the method advantageously a plurality of first holding devices, which are arranged on a first rotatably mounted star or wheel-like holding device carrier, with a plurality of second holding devices, which arranged on a second rotatably mounted star or wheel-like holding device carrier are, cooperation. On the first holding devices, an outer shell is prepared so far that it can be transferred to a transfer station to the second holding devices and there merged or joined with the inner cup. It is advantageous that the machine is relatively compact due to the use of wheel or star-like holding device carriers. Also rad- or star-like structures are relatively easy to produce and little prone to error. Thus, a robust, compact and less error-prone machine is created, which also allows very short cycle times. "Done" in the context of the invention is not necessarily "completely finished", but refers to the achievement of at least the state of the outer shell / the inner cup / cup, which is absolutely necessary for the implementation of the upcoming work step. For example, the outer shell before gluing can still be unprinted and (eventually) printed later. "Ready" for the gluing means, for example, that the outer shell is wrapped and the adhesive flaps are coated with adhesive.
Advantageous embodiments and modifications of the invention will become apparent from the dependent claims and from the description in conjunction with the figures of the drawing.
An advantageous variant of the machine according to the invention comprises the following components: a plurality of third holding devices which are arranged on a third rotatably mounted star or wheel-like holding device carrier, at least one third work station arranged in the region of the third holding devices for carrying out at least one of the steps: separating the finished one Inner cup from a stack, applying adhesive to the outside of the inner cup and - a transfer station for transferring a finished inner cup from a third holder to a second holder.
In this way, inner cup, which are not yet ready prepared to be delivered to the machine according to the invention to be directly connected to the outer shell, still be prepared within the machine according to the invention. For example, an adhesive can be applied to the inner cup, so that it bonds well with the outer shell. In a particularly advantageous variant of the invention, the transfer station consists of a compressed-air nozzle in a third holding device, with the aid of which the inner cup is transferred from a third to a second holding device can. In principle, other transfer stations may consist of a compressed-air nozzle, for example the transfer station between the first and second holding devices. This works particularly well if the outer shell is also designed in the form of an (outer) cup.
Another embodiment is characterized in that the machine has a separating station for carrying out the separating step of inner cups, wherein the separating station comprises a plurality of separating elements, which separating elements are arranged distributed over the circumference with respect to a conveying axis defined by a tube. This creates the possibility, immediately after the step of Vereinzeins without further steps to bring the isolated inner cup directly into the designated second holding device or to use. In the respectively provided second holding device previously a finished outer shell has been used and optionally positioned.
Furthermore, it may be advantageous if the separating station for carrying out the separating step of inner cups comprises a plurality of separating elements, which separating elements are arranged distributed over the circumference with respect to a conveying axis defined by a pipe. Thus, a sufficiently accurate separation can be performed.
Another embodiment is characterized in that each of the separating elements is arranged adjustable in the radial direction with respect to the conveying axis. This makes it easy to convert the machine to different cup cross sections. The radial adjustment can be done automatically and independently. But it would also be a common, central adjustment of the separation elements at the same time possible.
A further possible embodiment has the features that the separating elements are cylindrical and at the outer peripheral portion of a helically extending separating groove is arranged or formed. This creates the possibility for you to ensure a secure engagement of the edge strips or sealing edges of the inner cup in the separating elements.
A further embodiment provides that at least three pieces of separating elements are provided. By providing three pieces of separating elements, cups with a round cross-section can be safely separated. Thus, a sufficient self-centering of the inner cup to be stacked between the separating elements can be achieved.
Another embodiment is characterized in that four pieces separating elements are provided. By providing four pieces of separating elements and inner cup with a polygonal, in particular a square cross-section, can be isolated safely.
Another embodiment is characterized in that in each case two pieces of the separating elements form a separating element pair and each of the separating elements of a separating element pair is arranged at a first end of a pivoting lever and each pivoting lever of a separating element pair with its second end in each case about a separate, common pivot axis is pivotable. As a result of the pairwise arrangement of the separating elements, a separate pivot axis for size adaptation to mutually different cross-sectional dimensions of inner cups to be separated can thus be created for each of the separating element pairs with their pivoting levers. This can be a rapid and central adjustment made to be carried out conversions. By preferably symmetrical adjustment of the pivot lever to each other in the manner of a scissor movement the
Adjustment can be carried out and so the cross-sectional adjustment easily done.
Furthermore, it may be advantageous if each of the pivot axes is arranged at a fixed radial distance from the conveying axis spaced. As a result, a fixed arrangement of each of the pivot axes can be achieved on the machine, wherein only by changing the relative position of associated pivoting levers at the same time a size adjustment to the cross section of the respective inner cup to be stacked can be made possible.
Another embodiment is characterized in that the separating station for carrying out the separating step of inner cups further comprises a feed device having a plurality, a particular horizontal orientation having transport bottoms and that the feed device has a near-bottom loading area and a floor remote transfer area. By providing a feed device modeled on a paternoster, a simple height-wise transport movement of individual stacks of inner cups from a feed area closer to the operator to a bottom-side transfer area can thus be made possible. As a result, the feeding of cup stacks toward the separating device of the separating station is made considerably easier even with such machines or systems.
Another possible embodiment has the features that the feed device has a pivoting device arranged in the transfer area, by means of which pivoting device a stack of inner cups can be pivoted from its particular horizontal position on the transport floor into a vertical position. This creates the possibility of relocating the individual stacks of inner cups from their first position having a horizontal orientation into a gravity-utilizing automatic transport position. It is advantageous if the machine is a preparation station for performing at least one of the following steps before the settlement of a
Outer shell has:
Singulating a transaction to form an outer shell from a stack,
Pre-bending of the seam area (in particular of the seam area located later inside),
Heating a seam area or the entire process,
Orders of adhesive in the seam area.
In particular, if the outer sheaths are not delivered ready prepared so that they can be wound directly around a first holding device, in the area of the machine according to the invention nor the necessary preparations can be made. The listed steps are to be seen as demonstrative examples. Of course, other or additional steps are possible.
Another possible and optionally alternative embodiment has the features that the preparation station comprises an adhesive application station for applying adhesive in the seam area, and that the adhesive application station comprises at least one first nozzle facing the seam area and at least one further second nozzle, each of which The nozzles each have a continuous bead of adhesive can be applied. This makes it possible to apply different adhesives to each other. Preference can thus be given to the orders of the adhesives in one operation at the same time.
A further preferred embodiment is characterized in that the at least one first nozzle is designed to dispense hot glue. Thus, a rapid setting time can be achieved in the seam area, so as to be able to carry out the further processing of the outer shell even faster in the machine
Furthermore, it may be advantageous if the at least one second nozzle is designed to dispense white glue. By combining mutually different adhesives, the basic strength of the seam area can be increased. Furthermore, this can also be achieved by the white glue higher temperature resistance of the seam area.
Another embodiment is characterized in that the at least one second nozzle for delivering white glue is in line connection with a container, and the line connection is closed and airtight and that the container has in its interior a relative to the ambient pressure to higher pressure. As a result of the airtight connecting line, it is thus possible to prevent premature evaporation of the water of the white glue serving as the solvent and, as a result, its drying out. This can also be additionally prevented by the pressure prevailing in the container interior pressure with respect to the atmospheric pressure. Thus, over a longer period of time, the viscosity of the white glue can be kept the same within narrow limits.
Furthermore, it can be advantageous if the adhesive application station comprises a first partial application station and a second partial application station, and that both partial application stations are arranged on a common holding arm and that the holding arm has a longitudinal extent in a parallel direction with respect to the conveying direction of the preparation station. In this way, the possibility can be created of being able to simultaneously apply mutually different adhesives to those blanks transported in succession in the preparation station. Furthermore, this can be done with a simple common application station, wherein only a single drive for the adjustment of the support arm is required for the transverse adjustment.
A further embodiment provides that the at least one first nozzle is arranged in the first partial application station and that the at least one second nozzle is arranged in the second partial application station and that the at least one first nozzle is at a predetermined conveying distance of at least one second nozzle relative to the at least one second nozzle one after the other in the preparation station to be promoted developments are arranged spaced from each other to form outer shells. This can be applied to two different, arranged immediately after one another in the conveying direction blanks for forming the outer shell each have their own bead of adhesive.
Another embodiment is characterized in that the holding arm with the at least two nozzles is guided parallel adjustable with respect to a conveying plane and transversely and in the vertical direction with respect to the conveying direction of the settlement and that the transverse adjustment and the application of the adhesives takes place simultaneously with the conveying movement of the unwinds , Thus, despite the adhesive application, a continuous conveying movement of the individual blanks in the area of the adhesive application station can be maintained. The extent of the transverse adjustment is to be selected depending on the inclination of the near area with respect to the conveying direction of the blank. Since the alignment of the blanks in their position is selected symmetrically with respect to the conveying direction, a reliable application of the adhesive, in particular of the adhesive beads, can be carried out here with relatively short adjusting movements of the holding arm and, associated therewith, with the at least two nozzles.
A further possible and optionally alternative embodiment has the features that, following the adhesive application station, at least one first sensor and at least one second sensor are arranged, which sensors are designed to control the adhesive bead applied by the nozzles. This can be done before the transfer of the prepared for the subsequent winding process blanks or developments a security check. If one of the adhesive beads is incomplete or missing, the blank may be eliminated from the processing cycle before it can later cause a machine failure.
A further embodiment provides that the at least one second sensor is designed as a moisture sensor, which serves to determine the moisture contained in the white glue. The white glue preferably contains water as an additive which, depending on the viscosity of the white glue, represents a higher or lower proportion, as a result of which the moisture content may also be different. The sensor can determine whether the white glue is present or not by determining the moisture contained in the white glue. When determining the total amount of moisture contained in an adhesive bead, it is also possible to check whether the adhesive bead is present continuously and also the amount of white glue applied complies with the specifications.
A further embodiment provides that the preparation station comprises a feed carriage and the feed carriage in each case has a holding and pivoting arrangement spaced apart from one another transversely to the conveying direction and the holding and swiveling arrangements extend from a position parallel to the conveying plane into one angular position towards the first holding devices are swung up. By means of this pivoting motion, which is on both sides with respect to the conveying direction, preforming of the respective blanks or developments can take place in the direction of an approximately U-shaped cross section. Thus, even before the takeover of the blanks or the unwinds on the first holding devices of both lateral longitudinal edges a predetermined distance can be covered, without the Anformvorgang begins at the respective holding device when contacting with the respective first holding device. Depending on the extent of the pivoting movement, which amounts to almost 90 °, preferably between 80 ° and 88 °, with respect to the mostly horizontal conveying plane, a whip effect of the longitudinal edges and thus also throw-off of adhesive can be minimized or prevented altogether.
Finally, a further embodiment of the machine has the features in which the transfer station comprises an auxiliary unit for transferring a finished outer shell from a first holding device to a second holding device, which auxiliary unit has at least two transfer elements arranged opposite one another in the transfer direction and the two transfer elements with respect to the transfer Outer shell to each other have an opposite direction of drive. Preferably, the transfer elements are formed roller or wave-shaped and can thus ensure a stabilization of the outer shape of the outer shell to be handed over, in which a proper insertion of each of the outer shells in the respectively intended second holding device is possible.
For a better understanding of the invention, this is based on the following

Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.
The term "in particular" is understood below to mean that it may be a possible more specific training or specification of an object or a method step, but not necessarily a compelling, preferred embodiment of the same or a compelling approach.
Fig. 1 shows a known cup 100 of composite material, namely an outer shell 101, in which an inner cup 102 is arranged. In this case, it is also possible to speak of a combination packaging container or of a combination packaging cup, since preferably the inner cup 102 and the outer shell 101 formed from a blank or a development are formed from mutually different materials. The outer shell 101 can be formed in a known manner from the blank to a circumferential sleeve.
In an overlapping area, mutually facing ends of the outer shell 101 are connected to each other by means of an overlapping seam formed by at least one adhesive. This connection section can also be referred to as a seam area, which is preferably strip-shaped.
Such cups 100 further have an open and a closed end region, wherein a conventional cross-sectional dimension in the open end region is greater than that in the closed end region. The open end region also usually has a flange-shaped edge strip 103, which can be connected to a closure device, in particular sealed. The preferably circumferential edge strip 103 can also be referred to as a sealing edge or sealing flange. Also, arbitrary cross-sectional shapes can be used, which may also be designed differently from one another. The cross-sectional shape may be round, non-round, oval or angular, in particular polygonal. Furthermore, each inner cup 102 as well as the outer shell 101 defines a longitudinal axis 104.
In principle, there are several methods to make this cup 100. One way is to wind the outer shell 101 around the finished inner cup 102 and connect the facing end portions to each other. In this case, the inner cup 102 is usually received by a mandrel, which takes over the support and support during the winding process.
Another possibility is to produce the inner cup 102 and the outer shell 101 independently of each other and then to join together, in particular to push together. The inner cup 102 may have a bead in the bottom region, which prevents the sliding down of the outer shell 101 from the mostly conical or tapered inner cup 102, if this is not or only slightly glued to the inner cup 102.
Another possibility is that the outer shell 101 is first produced from the blank or the unwinding and this is inserted before the manufacturing process of the inner cup 102 in the intended for this molding process mold cavity of the mold. The production of the inner cup 102 is made for reasons of cost, preferably in a deep-drawing process starting from a film-like layer of a thermoformable material.
The present invention relates to that manufacturing variant in which a finished outer shell 101 and a finished inner cup 102 are pushed into each other.
The inner cup 102 and the outer shell 101 are usually made of different materials. For example, the inner cup 102 is often made of plastic or other thermoformable material and the outer shell 101 of paper, cardboard or a plastic film. These can still be printed before the assembly or forming the outer shell of the settlement or the blank. It is also conceivable, for example, that the inner cup 102 is made of foiled cardboard. Furthermore, the outer shell 101 may also be made of plastic, in particular of foamed plastic. In addition, the outer shell 101 may be configured not only in the form of a cuff but also in the shape of a cup. In this case, two cups, namely the inner cup 102 and the outer shell 101 forming outer cup, are pushed together. Finally, it is also conceivable that the cup 100 consists of three nested materials, such as an inner cup 102 made of (smooth) plastic, an intermediate cup made of foamed plastic and an outer shell 101 made of paper or cardboard.
The different materials of a cup usually also perform different functions. For example, the inner cup 102 should prevent leakage of liquid contained therein, while the outer casing 101 should be well printable and, optionally, should also provide thermal shielding to the cup contents. Finally, the idea of environmental protection when using a cup made of composite material plays a crucial role.
The masses of disposable cups that are needed on a daily basis, require highly automated manufacturing processes or machines for producing the same. Although the currently known methods or machines meet existing needs, there is room for improvement, in particular to be able to cope with the future - in all likelihood increased - demand for disposable cups or to reduce the number of parallel machines.
2 shows a possible embodiment of a machine 1 in a greatly simplified representation. The machine 1 comprises first holding devices 2, here in the form of spikes, which are mounted on a first star-shaped or wheel-shaped holding device carrier 3. The machine 1 further comprises second holding devices 4, here in the form of sleeves or rings, which are mounted on a second star-shaped or wheel-shaped holding device carrier 5. The longitudinal axes defined by the sleeves or rings have a radial orientation with respect to the axis of rotation of the second holding device carrier 5. Thus, longitudinal axes of the sleeves or rings have an orientation in the direction perpendicular to the axis of rotation. Furthermore, it may also be advantageous if the second holding devices 4 designed as sleeves or rings have a recess or an opening in that inner peripheral region or circumferential section in which the overlap region with the overlapping seam of the outer casing 101 is later located. This can prevent soiling and unwanted deposits of adhesive.
Hereinafter, a part of the manufacturing process of a cup 100 will be explained. Before that, however, it should be pointed out that the work steps required for this purpose are shown merely symbolically, since a representation of the respectively assigned workstations of the machine 1 would damage the clarity in all details. In the following, reference will be made only to working steps, of course, but in the following explanations, the respective associated, objective work stations are meant.
Furthermore, it is pointed out that, between the working steps, the first or the second holding device carriers 3 and 5 continue to rotate by one position. The rotational movement is thus discontinuous. The rotational movement advantageously stops only for a certain period of time, which corresponds to the time required for the long-lasting operation. Therefore, it is also particularly advantageous to divide long-lasting steps into several individual steps:
In a first operation A1 or at a corresponding workstation, a development or a blank for forming an outer shell 101, which is wetted with adhesive in the vicinity, is delivered and aligned (see also FIGS. 3 and 4). This step serves to provide A1 of the blanks or unwinds to form the outer shells 101 and may take place in a staging station A1. In this step, the blanks or developments are mostly planar and horizontally aligned.
The fixation of the development on the first holding device 2 forming mandrel can be maintained by means of a terminal block or else by means of a mandrel formed or constructed suppressor. For this purpose, each of the mandrels on its leading in the direction of rotation side at least one, preferably a plurality of openings 22, in particular bores, which are formed as suction inputs. The openings are connected to a vacuum generator, not shown in line connection. The arranged in the mandrel openings 22 are arranged on the first holding devices 2 respectively on the seen in the direction of rotation of the first holding device carrier 3, the front peripheral region. In this section, the first system of settlement takes place on the holding device. 2
In a second step A2 in a winding station A2, the provided development is wound around the mandrel. For this purpose, for example, pincer-like moving levers can be used, which press the settlement against the mandrel. In a particularly advantageous variant, the settlement during the rotational movement of the first holding device carrier 3 with the help of laterally arranged next to the thorns, fixed brushes U-shaped applied to the mandrel and then completely wound with not shown pivoting levers or pincers moving levers around the mandrel , It becomes clear from this example that the production steps can not necessarily take place only when a holding device carrier 3 and / or 5 is at a standstill, but also during their movement.
In a pressing station A3, the seam, in particular the overlapping seam, of the wound blank is pressed to form the finished outer shell 101 in a third working step A3. For this purpose, a movable punch, in particular a heated punch, provided which presses the two ends of the development of the outer shell 101 against each other and to the first holding device 2, in particular the mandrel. The following two stations are empty and serve to cure the adhesive. It is also conceivable that optional workstations can be retrofitted at these positions.
The stamp, if it is part of a workstation, can be released once the adhesive has sufficient adhesive force to prevent the outer shell 101 from falling apart. The stamp can also be part of a first holding device 2. In this case, it can be connected to a clamping lever 14, which is adjustable, in particular pivotally guided or mounted on the first holding device carrier 3. Since the clamping lever 14 or the stamp is indeed moved with the holding devices 2, this remains closed until the adhesive is cured and thus pushes the two to be joined and overlapping ends of the settlement to form the erected outer shell 101 together and this to the first Holding device 2 or its mandrel. This variant is advantageous in that the cycle times are not unnecessarily prolonged because of the curing of the adhesive.
In a first transfer station A4 takes place in a fourth step A4, the transfer of the finished outer shell 101 to a second holding device 4. The second holding device 4 may be formed by a ring or a sleeve.
The fourth step A4 is at the same time the first step B1 in the area of the second holding device carrier 5. The transfer can be effected, for example, by a displaceable ring or a sleeve-shaped slide (in this example forms a transfer station 6) which at least releases the finished outer casing 101 from the mandrel or even stripped off and optionally simultaneously inserted into the second holding device 4, in particular the ring. In this case, the transfer or the takeover of the finished outer shell 101 or the cuff can also be effected by a directed medium flow, in particular an air flow.
Optionally, the outer shell 101 can be pulled by means of a vacuum in the second holding device 4, in particular the forming this ring or a sleeve. It is also conceivable that the outer shell 101 is removed by means of pliers from the mandrel. A possible transfer with the required devices or units will be described below by way of example.
After the transfer step A4 - B1 at the transfer station A4 or 6, the outer shell 101 can be nachsetzgesetzt B2 in a Nachsetzstation B2, that is correctly inserted into the receptacle of the second holding device 4, in particular the ring or the sleeve in the next step B2, since their correct fit at the transfer station 6 can not always be guaranteed with sufficient accuracy. Guide rods 7 advantageously prevent the outer shell 101 from falling out should it not correctly seat the second holding device 4 and thus no secure hold by the vacuum be possible. In a next step B3, the prefabricated inner cup 102 is inserted into the outer shell 101 in an insertion station B3.
In an advantageous variant of the inner cup 102 is pressed with the aid of compressed air from a tube and can be spent in the prepositioned held outer shell 101. The separation of the inner cup 102 from a stack thereof, will be described in more detail below.
The transfer or takeover of the isolated inner cup 102 can be done by means not shown transfer means. For example, the transfer means may be rod-shaped, with a vacuum mount being arranged on the end thereof which can be turned towards the bottom of the inner cup 102.
This can e.g. a suction cup with a suction inlet of a vacuum unit. Thus, the transfer means can be adjusted from the cup bottom detecting and thereby projecting through the ring of the second holding device 4 through position into the arranged within the second holding device carrier 5 position.
In a subsequently arranged indentation station B4, the inner cup 102 can be pushed in or pushed into the outer casing 101 in a subsequent step B4. This may be the case if in the course of the insertion process, no complete latching between the bead of the inner cup 102 and the bottom edge of the outer shell 101 facing the bottom has taken place. By pressurizing or by means of a punch, not shown, it can be achieved that the bottom of the inner cup 102 is curved in the axial direction and thus the engagement of the attached to the inner cup 102 bead is facilitated. The buckling of the bottom serves to reduce the outer dimension of the inner cup 102 in its bottom area to such an extent, and thus the clear passage cross section on the outer shell 101 does not have to be overstretched.
Optionally or additionally, the inner cup 102 may already be supplied wetted with adhesive. Optionally, the bead in the bottom region of the inner cup 102 can be omitted if the adhesive ensures that the outer shell 101 reliably adheres to the inner cup 102. The latter, however, is disadvantageous in that it makes the separation of waste after use of the cup 100 more difficult. Optionally, the Nachsetz can be omitted. Thus, the working steps B3 and B4 or the workstations provided for this purpose can also be combined, for example when the inner cup 102 is inserted into the outer shell 101 at high speed.
In a control station B5 is checked in a further step B5, whether the cup 100 was made properly (here symbolized with a camera). If this is not true, the cup 100 is conveyed into a waste container in a sorting station B6, for example via a pipe system in step B6.
If the cup 100 is in order, it is taken to a removal station B7 in a last step B7 of the second holding device 4, in particular its ring or sleeve. This can be done for example by means of a blast of compressed air, which blows the cup 100, for example in a connected delivery pipe. One of the workstations, in this case the workstation B8, is not occupied with its own work step and thus free. But it would also be possible to provide this free station elsewhere or at a necessary additional step to occupy this with the designated workstation. This order is chosen only as an example and can be freely adapted to your needs.
As mentioned, the inner cup 102 may already be supplied wetted with adhesive. This preparation can also be done in the machine 1. In the following the necessary steps are explained:
In a separating station C1, the inner cups 102 delivered in a stack are singled out in a first working step C1 and subsequently placed on a third holding device 8. The third holding devices 8 are arranged on a third holding device carrier 9. The singling can take place with the aid of rollers with a spiral groove, in which grooves the cup rim engages. This separation station will, as indicated earlier, follow described in more detail below.
The third holding device carrier 9 moves in time with the two other holding device carriers 3 and 5, thus moving the inner cup 102 to the next workstation.
In a first adhesive application station C2, in a second step C2, the inner cup 102 can be wetted by means of nozzles with adhesive, in particular with a hot adhesive, such as e.g. a hot glue, a hotmelt. The next workstation is again shown empty. In a last step C3 we now in a further transfer station C3 of the optionally wetted with adhesive inner cup 102 of the third holding device 8 is inserted into the provided outer shell 101, in particular pushed into it. The third holding devices 8 can also be formed, for example, each by a mandrel. The step C3 thus corresponds to the step B3.
The arrangement of the individual holder carrier 3, 5 and 9 to each other can be made so that their axes of rotation to each other have a parallel orientation. If the individual holding device carriers 3, 5 and 9 are arranged in a lying position, their axes of rotation are vertically aligned. However, for reasons of space, the individual holding device carriers 3, 5 and 9 are preferably arranged upright, so that their axes of rotation each have a horizontal orientation. In this case, the axes of rotation can not only be parallel to each other, but also crossing each other, but horizontally aligned. The view shown in FIG. 2 is a vertical arrangement of the holding device carriers 3, 5 and 9 with horizontal axes of rotation arranged parallel to one another.
In the following, a preparation station 25 for providing unwinds or blanks for forming outer sheaths 101 will be described by way of example, wherein in FIG. 2 this is indicated only in dashed lines.
However, it would also be possible to completely dispense with the provision of the third holding device carrier 9 in the machine 1 and subsequently to the separating station C1 with the step of separating C1 of a stack delivered to the respective individual inner cup 102 directly to the further transfer station C3 promote. At the transfer station C3 - B3, the inner cup 102 can be injected, for example, with compressed air. It would also be possible to carry out the transport of the individual isolated inner cup 102 starting from the separating station C1 to the transfer station C3 by means of air as the means of transport. The conveying path could be e.g. take place within a pipe.
FIGS. 3 and 4 show a possible and optionally independent embodiment of a preparation station 25 for providing a development, again using the same reference numerals or component designations for the same parts as in the preceding FIGS. 1 and 2. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 and 2 or reference.
Here, an arrangement for providing a blank is shown, in which the unwinds or blanks are delivered in a stack and separated from this stack in the preparation station 25. The individual possible steps and the associated workstations are explained below.
The individual developments for forming the outer shell 101 are separated from a stack in a separating station D1 in a first working step D1. The isolated blank or the individual processing is transferred from the separating station to a conveyor. The conveyor is here formed by a cooperating pair of conveyor belts 10, which take over and further convey each of the blanks. Seen in the conveying direction, the pairs of conveyor belts 10 are arranged at a distance from one another transversely to the conveying direction and clamp between them a conveying plane 15 for the blanking. Preferably, the conveying plane 15 is oriented horizontally.
In a pre-bending station D2, in a second step D2, the adhesive flap forming the seam area, in particular the laterally inner flap, can be pre-bent, so that the outer surface 101 laterally becomes as flat as possible in terms of roundness in its overlapping area or seam area.
In the preparation station 25, it is also possible to carry out a third operation D3 in a heating station D3 in which the unwinding or the blank is heated at least in sections. In this case, only that portion of the settlement can be heated, which forms the tabs to be bonded. The station of pre-bending or pre-breaking - D2 - of the seam area is here arranged on that side of the preparation station 25, at which the inside of the finished outer shell 101 in the seam area end of the settlement is conveyed past.
In a further, subsequent work station, namely an adhesive application station D4, the adhesive application takes place in a fourth work step D4. In the present embodiment, the Vorbiegestation D2 is arranged at the other end than that of the adhesive application. For the adhesive application, a plurality of first nozzles 13 and / or a plurality of second nozzles 17 may be provided. This creates the possibility of being able to apply different adhesives to the longitudinal edge area of the blanks provided in the seam area to be formed. If the nozzles 13 and / or 17 combined to form a common adhesive applicator head 23, a common adjustment movement can be performed.
In the exemplary embodiment shown here, the adhesive application can take place in the course of a simultaneous movement of both at least one first nozzle 13 and / or at least one second nozzle 17 and the blank or the unwinding in its transport direction by means of the conveyor belts 10.
The at least one first nozzle 13 and / or the at least one second nozzle 17 serve or serve to apply the adhesive in the seam area, whereby this is guided adjustably parallel to the conveying plane and transversely with respect to the conveying direction of the unwinding. The transverse adjustment of the nozzle 13 and / or 17 is preferably carried out in the vertical direction with respect to the conveying direction of the settlement. This is simplified by a double arrow. This transverse adjustment of the nozzle 13 and / or 17 for applying the adhesive takes place simultaneously and coordinated with the conveying movement of the settlement. As a result, at correspondingly coordinated movement speeds relative to one another (feed rate of the unwinding by the transport speed of the conveyor belts 10 and the rectilinear adjustment speed of the adhesive applicator head 23 with the at least two nozzles 13, 17) between the nozzle 13 and / or 17 and the unwinding respectively a preferably continuously trained first adhesive bead 16 and / or several additional additional adhesive beads 24 are applied side by side. Preferably, the adhesive beads 16, 24 are arranged or applied parallel to one another and also predominantly parallel with respect to the longitudinal edge of the blank or the unwinding.
Due to the cup wall extending mostly conically from the open end to the closed end of the cup 100, the blank has the shape of a circular arc section in the case of a round cup cross section. During the conveying movement of the blanks or the still planar windings, the respective radial center axes of the circular arc sections are always aligned in a parallel direction with respect to the conveying direction and thus parallel with respect to the longitudinal extent of the conveyor belts 10. The two longitudinal edges of the blank or the unwinding have an oblique to the conveying direction longitudinal course. The inclination of each longitudinal edge with respect to the conveying direction or the longitudinal extent of the conveyor belts 10 corresponds to half the angular value of the full circular section of the blank or the development, which is enclosed by the two longitudinal edges.
In hitherto known adhesive application devices, the further transport of the development in the area of the adhesive application station has been stopped and carried out with the aid of an angular position of the longitudinal edge of the blank or the development with respect to the conveying direction, corresponding angular movement with respect to the conveying direction of the adhesive application by means of a nozzle.
In the present case, it is provided that the first nozzle 13 to assign the additional nozzle 17 for the adhesive application or immediately next to it and so in a single, common motion simultaneously apply two such adhesive beads 16, 24 in the region of the tabs to be bonded. The two adhesive beads 16, 24 are here applied in the region of that tab, which is arranged lying outside in the finished wound and connected state of the outer shell 101.
After the adhesive has been applied, the unwinding is transferred to a feed carriage 18 by means of the cooperating conveyor belts 10 at their end facing the first holding device carrier 3. On this feed carriage 18 are preferably lateral guide rails 11 and in the conveying direction the position defining stop blocks 12 are arranged. The settlement is in the prepositioned position on the feed carriage 18, are formed on this means for holding the same. In this case, the feed carriage 18 is adjustable from a position taking over the unwinding of the conveyor belts 10 into the position-A1 -providing the unwinding-to the first holding device 2 of the first holding device carrier 3. In this way, the unwinding is conveyed from the area of the conveyor belts 10 into the swivel area of the first holding devices 2 in the region of the first holding device carrier 3. This transferred position of the settlement is shown in FIG. 4. The feed carriage 18 is indicated here only in simplified dashed lines.
In the arrangement of the holding device carriers 3, 5 and 9 with the horizontally oriented axes of rotation selected here, the first holding devices 2 of the first holding device carrier 3 are arranged on the horizontal in the horizontal direction for the takeover of the blanks or unrolls prepared for the winding process Conveyor plane 15 located blanks or developments to move.
The above-described means for holding the unwinding on the feed carriage 18 are here formed by bearing surfaces 19 distanced from one another in the transverse direction with respect to the direction of movement of the feed carriage 18, in which
Inlet openings 20 open. These are conductively connected to a suction inlet, not shown, of a vacuum generator. As a result of the built-up vacuum, the unwinding conveyed by the conveyor belts 10 is taken over and held in the positioned position on the feed carriage 18. In this prepositioned and held position, the adjustment of the feed carriage 18 takes place in the swivel range of the first holding device 2.
The delivery carriage 18 provides and transfers A1 - D5 from the preparation station 25 to the first holding device carrier 3 with its first holding devices 2.
Furthermore, it is shown in simplified form here that between the transversely spaced support surfaces 19 of the feed carriage 18 in this a recess 21 is formed, through which when providing - A1 - the development to form the outer shell 101, at least the first holding devices 2 during the rotational movement moves therethrough can be. Thus, for the transfer of the settlement from the feed carriage 18 toward the first holding device 2, the unwindings are held until the takeover of the first holding device 2 has taken place, as has already been described above. Immediately following the takeover of the settlement from the feed carriage 18 to the first holding device 2, the shaping of the blank is carried out to the finished rolled or wound outer shell 101.
As mentioned, the development of the outer shell 101 can also be supplied already wetted with adhesive. The preparation of the settlement can also be done in the machine 1.
It should be noted at this point that the axes of rotation of the holding device carriers 3, 5 and 9 do not necessarily have to be parallel, as shown in FIG. 2. The axes of rotation of the holding device carrier 3, 5 and 9 can also take any angle to each other, as long as care is taken that the axes of the holding devices 2, 4 and 8 are aligned at the transfer stations or at least arranged so that a smooth transfer of the outer shell 101st and / or the inner cup 102 is ensured.
In the fourth step D4 of the adhesive application in the further adhesive application station D4, mutually different adhesives or adhesives can be used. Thus, it would be possible, for example, to deliver a so-called hot-melt adhesive, hot glue or hotmelt onto the seam area by means of the first nozzle 13. From the further nozzle 17, for example, as an adhesive, a commercial white glue (low-formaldehyde dispersion glue) can be used. In this customary way usually a PolyVinylAcetat (PVAc) is used as a binder, which is mixed with water as a dispersion ready for use. By using different adhesives, the setting time and the later temperature resistance of the adhesive seams can thus be matched to one another depending on the intended use and requirements of the cup 100.
Thus, for example, by using the hot glue or hot melt rapid setting and mutual support of the overlapping ends of the blank can be achieved in the seam region. The white glue o-the cold glue used has a longer setting time with respect to the hot glue but has a higher temperature resistance compared to this.
The adhesive beads 16, 23 applied by the two nozzles 13, 17 are preferably applied continuously over the longitudinal extent of the seam area. It should also be noted that the arrangement or sequence of the two adhesive beads 16, 23 with respect to the longitudinal edge of the blank is shown only by way of example. Thus, either each of the two adhesive beads 16, 23 may be arranged closer to the outer longitudinal edge of the blank than the other. The other of the adhesive beads 23, 16 is then arranged further apart from the outer longitudinal edge. Thus, either the hot glue or hotmelt or the white glue can be arranged closer to the outer longitudinal edge of the blank or the unwinding.
It would also be possible, e.g. apply or apply three juxtaposed adhesive beads in the intended seam area. Thus, the first nozzle 13 for applying the hot melt adhesive and the adhesive bead 16 formed therefrom could be arranged between two nozzles 17 arranged laterally next to it for applying two adhesive beads 23 from the white glue. Thus, a rapid and short-term adhesion of the seam area can be achieved by means of the hot melt adhesive or hot glue, wherein from the other two adhesive beads 23 from the white glue a durable, temperature-resistant connection is created.
To be able to monitor and control the orderly application of at least one of the two adhesive beads 16 and / or 23, at least one of the adhesive beads, but preferably both of them, can each have its own sensor 26, 27 assigned to it. The two schematically indicated sensors 26, 27 may be in communication communication, in particular line connection, with an evaluation device not shown in detail and, if appropriate, subsequently with the machine control.
For detecting the first adhesive bead 16, which is formed for example by the hot glue or hotmelt, the sensor 26 could be designed as a thermal sensor which detects or detects the thermal radiation emitted by the hot glue or hotmelt. The sensor 26 could also be formed by a thermal imaging camera so as not only to be able to determine the presence of the first adhesive bead 16, but also to be able to determine its arrangement along the longitudinal extent of the longitudinal edge of the blank or the unwinding.
The further sensor 27 is adapted to detect the presence of the white glue. For this purpose, different detection methods can be used. Depending on the selected detection method, the sensor 27 designed for this purpose must also be selected. In principle, this sensor 27 can be referred to as a moisture sensor.
A first way to detect the presence of the white glue would be to add fluorescent ingredients, in particular a fluorescent powder. With a lighting means, such as a UV lamp, the fluorescent components or the fluorescent agent, such as the powder, can be excited to emit light radiation.
This emitted light radiation can be determined by the further sensor 27, wherein the further sensor 27 may also be an evaluation device, not shown in detail, and optionally subsequently in communication communication with the machine control, in particular line connection.
As mentioned briefly above, the white glue is dispersed with water. For example, with the sensor 27, the water added to the white glue, in particular its water content, could be determined. This would also provide an indication of the amount as well as the presence of the white glue. Thus, by means of the two sensors 26 and / or 27 on the proper presence of the adhesive beads 16 and / or 24 are closed. Should it be determined by one of the sensors 26 and / or 27 that one of the adhesive beads 16 and / or 24 is not present, this may subsequently lead to the immobilization of the machine 1, so as to avoid the production of rejects. For proper application of the white glue and its viscosity is not insignificant. Furthermore, but also blockages in the leads to the other or second nozzle 17 can be avoided. If the consistency of the white glue too thin, so the viscosity is very low, the further bead of adhesive 24 could pass or even be thrown during the winding process of the blank to the finished outer shell of the intended adhesive flap. By adding water, the flow properties and thus the viscosity of the white glue can be adjusted to the respective application conditions. Since the water content is reduced to bind the white glue, care must be taken that the white glue always has a predetermined viscosity and therefore a sufficient water content before the application of the adhesive bead 24.
For storing the white glue is still provided here that this is stored stored in a container 28. By means of a closed, airtight system, the white glue, for example, with an unspecified high-pressure pump to the adhesive applicator head 23 and located there further nozzle 17 are supplied. In addition, it is still possible that the container 28 in its interior with respect to the ambient pressure to higher
Has pressure or spent. As a result of the additional pressure build-up in the interior of the container 28, evaporation or the discharge of the water from the white glue can be prevented.
FIGS. 5 to 7 show a possible embodiment of a separating station C1 for isolating inner cups 102 from a stack provided, which is possibly independent of itself, again with the same reference numerals or component designations for the same parts as in the preceding FIGS. 1 to 4 be used. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 4 or reference.
The separating station C1 is used to carry out the step of separating C1 of inner cups 102, which are fed to the machine 1 mostly in a stack form of similar inner cups 102. The unstacking or the separation can be carried out by means of a separating device 29 shown in a simplified manner. Each of the inner cups 102 usually has the edge strip 103 described above, which in the present exemplary embodiment serves for the ordered separation and a stacking of the inner cups 102 in cooperation with the separating device 29 of the separating station C1.
The separating device 29 of the separating station C1 comprises a plurality of roller-shaped separating elements 30, which are arranged distributed over the circumference of the inner cup 102 on the machine 1. At each of the separating elements 30, a helically extending separating groove 31 is arranged or formed on its outer peripheral region. It would also be possible, instead of the groove-shaped recess at least one snail-shaped separating web on the outer surface of the separating element 30 to arrange or form. By selected in a known manner slope of the separating grooves 31 and carried out for the separation process pivotal or rotary movement of the individual separating elements 30, a single inner cup 102 separated from the stack and optionally to the third holding device carrier 9 with the third
Holding devices 8 or even passed directly to a second holding device 4.
As a material for forming the separating elements 30, a steel can be used. In addition, at least one partial section, but preferably the entire cylindrical outer surface together with the singling groove 31, may be provided with a zirconium coating.
As can now better be seen from FIG. 6, for example, with inner cups 102 having a round cross-section with three separating elements 30 distributed over the circumference, the delivery can be found. The separating elements 30 are preferably arranged distributed uniformly over the circumference, wherein in each case an offset angle of 120 ° is enclosed in a plane aligned perpendicular to the longitudinal axis 104 of the inner cup 102.
Furthermore, it is indicated here that each of the separating elements 30 is adjustable in the radial direction with respect to the longitudinal axis 104. This is indicated by double arrows
The adjustment of the separating elements 30 preferably takes place synchronously with each other and can take place by means of an adjustment mechanism not shown together for all separating elements 30. This can be reacted quickly to different dimensions in the inner cups 102 to be separated. The adjustment mechanism may be used for adjustment e.g. from a common drive element, e.g. a servomotor, a stepping motor, a cylinder-piston assembly or the like, to be driven. This allows an operator to easily and without high adjustment and retooling the desired change from a cup dimension to another different cup dimension perform.
The supply of the stack of inner cups 102 to be separated can take place within a tube 32. The tube 32 in turn defines a conveying axis 33. Preferably, each of the inner cup 102 with its longitudinal axis 104 in such
Tube 32 out that the longitudinal axis 104 is aligned congruent with respect to the conveying axis 33. Thus, the separating elements 30 are preferably also arranged and aligned radially relative to the conveying axis 33 of the tube 32.
The machine 1 should also be used universally for inner cup 102 with a variety of cross-sectional dimensions and / or cross-sectional shapes for their processing. Depending on the cross-sectional dimension of the inner cup 102 with its edge strip 103 is still provided that the separating elements 30 are arranged adjustable in their radial distance with respect to the conveying axis 33 and on the machine 1, in particular at the machine frame, held. This adjustability is indicated in each of the separating elements 30 with a double arrow in the radial direction. The radial adjustment of the separating elements 30 preferably takes place uniformly and concentrically with respect to the conveying axis 33 of the tube 32.
Furthermore, each of the individual separating elements 30 could be guided separately adjustable and optionally held clamped. Advantageously, however, all separating elements 30 of the separating device 29 could be adjusted simultaneously and synchronously with respect to the conveying axis 33 in their radial distance.
FIG. 7 shows the separating device 29 of the separating station C1 in a slightly modified embodiment, as has already been described previously in FIG. 6. The basic structure of the separating elements 30 is selected analogously to the separating elements 30 described above. Each of the separating elements 30 in turn has at least one separating groove 31.
In contrast to FIG. 6, in which three pieces of separating elements 30 are provided, the separating device 29 of the separating station C1 here comprises four pieces of such separating elements 30. As can be seen from an end view in the direction of the conveying axis 33, here not only inner cup 102 with a round cross-section, but also inner cup 102 with a deviating, in particular polygonal cross-section, can be separated. Again, the individual separating elements 30 are in turn arranged or formed in the radial direction with respect to the conveying axis 33 of the tube 32 and the longitudinal axis 104 of the inner cup 102 to adjustable. In each of the adjustment movements for adaptation to the most varied cross-sectional shapes of the inner cup 102, the adjustment of the separating elements 30 takes place in the vertical direction with respect to the conveying axis 33 or longitudinal axis 104.
So it is again possible, for example, in each case with respect to the conveying axis 33 or the longitudinal axis 104 diametrically opposed separating elements 30 synchronously or jointly in the radial direction form or arrange adjustable. This can be done quickly with their separating elements 30 for conversion from a cup shape or a cup dimension to a different other cup shape or another cup dimension quickly.
Of course, it is also possible to separate by means of the separating device 29 with four pieces of separating elements 30 and round or oval cup shapes.
After the step of separating C1 of an inner cup 102 from the stack of similar inner cups 102, the further transport thereof can also take place directly and without interposition of the third holding device carrier 9 on one of the second holding devices 4 of the second holding device carrier 5. During this transfer, the inner cup 102 is then introduced directly into the outer casing 101 already in the second holding device 4. The further subsequent steps B4 to B8 can be carried out analogously, as previously described in FIG. 2. It is also possible to omit individual steps B4 to B8 or the workstations B4 to B8 provided for this purpose, or to exchange their sequence relative to one another.
A possible embodiment of an adjusting mechanism 39 for the common and central adjusting movement of the individual separating elements 30 is shown and described in the following FIGS.
FIGS. 8 and 9 show a possible and optionally independent embodiment of a transfer station A4-B1 for transferring wound and finished outer shells 101, again with the same reference numerals and component designations for the same parts as in the preceding FIGS. 1 to 7 be used. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 7 or reference.
In contrast to the transfer station A4-B1 shown in FIG. 2 or the transfer step A4-B1 of a finished wound outer shell 101 to a respective second folder device 4 of the second folder carrier 5, the transfer direction is not rectilinear here by first aligned with one another and second flattening devices 2, 4, but this takes place with an angular orientation of the body axes or longitudinal axes formed by the first and second flattening devices 2, 4 relative to each other.
The formation of the first Flaltevorrichtungsträgers 3 with its first Flaltevorrichtungen 2 and the workstations A1 to A4 and thus executable steps A1 to A4 can be carried out analogously, as has already been described in detail in FIG. Furthermore, the previously described preparation station 25, which is not shown here in detail, can also be part of the machine 1.
The two axes of rotation of the first and second Flalteinrichtungsträgers 3, 5 are in turn arranged parallel to each other. Likewise, a so-called standing arrangement of the Flaltevorrichtungsträger 3, 5 are selected. In this case, the two axes of rotation of the Flaltevorrichtungen 3, 5 are each arranged in a horizontal plane, which may preferably be arranged offset to one another. Thus, it would be possible to arrange the two Flaltevorrichtungsträger 3, 5 not only in the vertical direction one above the other or next to each other, but also in an approximately horizontal orientation to each other. The formed as rings or sleeves second Flaltevorrichtungen 4 with the body axes or longitudinal axes defined by these, in contrast to the illustration in FIG. 2, a parallel alignment with respect to the axis of rotation of the second
Holding device carrier 5 on. In this case, the insertion of the wound and glued outer shells 101 and subsequently the inner cup 102 does not take place in a radial or vertical orientation with respect to the axis of rotation, but in a parallel direction with respect to the longitudinal axis of the second holder carrier 5.
Thus, in this embodiment, the transfer to the transfer station 6 or A4 in the form of a combined pivoting and / or tilting movement and optionally a sliding movement to perform. If the finished outer shell 101 is located on the first holding device 2 and in the transfer station 6 or A4, the outer shell 101 is to be detected by means of a transfer device 34 and in a kind of pivoting movement with its longitudinal axis 104 in an approximately aligned arrangement or orientation with respect to spend the sleeves or rings defined body axis or longitudinal axis of the second holding device 4. Is the outer shell 101 spent with its longitudinal axis 104 in alignment with the body axis or longitudinal axis of the outer shell 101 receiving sleeve or ring, the further transport or the insertion of the outer shell 101 is carried out by means of a gaseous transport medium, which is ejected by a transport device 35, which a nozzle is indicated schematically. The gaseous transport medium can be formed for example by compressed air. For the transfer process, the suction effect and, associated therewith, the holding of the outer shell 101 at the transfer device 34 must be interrupted. Thus, the release of the outer shell 101 from the suction head of the transfer device 34. At least at this time, but preferably immediately before, the outflow or expulsion of the gaseous transport medium from the transport device 35 is carried out.
At the opposite end of the second holding device carrier 5 is still indicated that an inner cup 102 is introduced in step C3 or right after the separating step C1 and a transport path not shown in the second holder 4, in which already the previously introduced outer shell 101 is located ,
As can now be better seen in FIG. 9, the transfer device 34 can be adapted in its contact surface 36 facing the outer shell 101 in approximately the cross-sectional shape or outer contour of the outer shell 101. In the contact surface 36 opens at least one mammal opening 37 which is connected via a line 38 shown in simplified form with a vacuum generator in line connection. Preferably, however, a plurality of mammal openings 37 are provided so as to ensure a proper and secure mounting of the outer shells 101 to be transferred during the transfer movement.
In the previously known transfer of the outer shell 101, this was also held by the transfer device with a vacuum suction and spent in a wasted position and passed on to its own gripping pliers. By means of the gripping tongs, the further transfer operation was carried out and the outer shell 101 was inserted into the second holding device 4. It often came to damage the outer shell 101 and subsequently to interruptions in the workflow of joining operations of the machine. 1
As a result of the pre-positioning of the individual outer shells 101 to be transferred with respect to the second holding devices 4 and the transport means formed by a gaseous pressure medium, a secure transport of the outer sheath 101 can be achieved with a flow direction aligned with the respective second holding device 4. Since most of the outer shells are conically tapered, an approximately linear transport movement of the outer shell 101 can be achieved in the receiving opening of the second holding devices 4 so by the generated and mostly aligned compressed air flow.
For stripping or stripping the wound outer shell 101 of the mandrel-shaped first holding device 2, a stripper sleeve or the like can be additionally used.
Finally, it should be noted that it is possible for each or each of the work stations described above, a detection device and / or a sensor may be provided in order to be able to control and monitor the particular work step and the associated work result. If a work step and the resulting work result do not match the predetermined or predetermined work result, either the blank or the unwinding, the outer shell 101 produced therefrom, the inner cup 102 or the entire cup must be eliminated.
There may also be provided a recognition device, by means of which recognition device the blanks or the flat segments e.g. are detected in their surface shape and a check is made or carried out to whether the provided inner cup 102 can be provided with the detected blank at all.
The monitoring or detection may also be directed to determine a multiple arrangement or multiple provision of directly superimposed and adhering blanks or unwinds immediately after the operation of Vereinzins D1 a settlement or a blank of a stack thereof. If this is determined, the preparation station 25 can be stopped to remove the blanks and so to eliminate the separation error. It would also be possible to carry out the subsequent subsequent steps in the preparation station 25 only on these blanks arranged one above the other and to eliminate them in the region of the feed carriage 18.
In the two FIGS. 10 to 13, a possible embodiment of the adjusting mechanism 39 is shown, wherein this relates to that arrangement thereof with a number of four pieces of separating elements 30, as indicated in FIG. The separating device 29 comprises, inter alia, the four pieces separating elements 30, wherein with this embodiment inner cup 102 or even already cups 100 made of composite material, namely combi Verpackungsbehäl ter, can be separated from a stack.
Thus, FIGS. 10 and 11 show the arrangement of the separating elements 30 for inner cup 102 with a circular cross-section with respect to their longitudinal axis 104. In each case two separating elements 30 arranged directly next to one another in the circumferential direction form a cooperating separating element pair 40, 41. Both separating element pairs 40, 41 are arranged diametrically opposite one another. Furthermore, each of the separating elements 30 of a separating element pair 40, 41 is arranged in each case on its own pivoting lever 42 or 43. This preferably takes place in a first end or a first end region of the respective pivoting lever 42 or 43. Each pivoting lever 42 or 43 of one of the separating element pairs 40, 41 is in its second end or its second end region about a pivot axis 44 common to the two pivot levers 42 or 43 or 45 pivotally mounted. Thus, it is also possible to speak of a first pivot axis 44 for the first pivot lever 44 and a second pivot axis 45 for the second or further pivot lever 45. The pivot axes 44 and 45 each have a parallel orientation with respect to the conveying axis 33 of the tube 32 or the longitudinal axis 104. The mutually diametrically opposite pivot axes 44 and 45 are preferably each arranged at a fixed radial distance 46 and 47 with respect to the conveying axis 33 of the tube 32 or the longitudinal axis 104 thereof distanced.
FIG. 10 shows the position of the two separating element pairs 40, 41 with their pivoting levers 42 or 43 for a round cup cross section and a larger cross sectional dimension thereof. In this position, the two associated pivoting levers 42 or 43 each between them a larger angle, as in that relative position to each other, in which an inner cup 102 or a completed cup 100 is to be isolated with a smaller cross-sectional dimension. This situation and relative position of the pivot lever 42 or 43 to each other is shown in FIG. 11. The pivoting movement of the pivoting levers 42 and 43 takes place in each case in a vertical plane with respect to the conveying axis 33 or the longitudinal axis 104 having pivoting plane.
For common adjustment of the two respectively associated pivoting lever 42 or 43 can be done by means of a separate actuator arm 48 or 49. Each of the actuating arms 48 or 49 may be mounted in the region of the respective pivot axis 44 or 45 and transmits the adjusting movement to the respective pivotally connected therewith pivot lever 42 or 43. By the respective change in the relative position of the two pivot levers 42 or 43 to each other can simply Adaptation to different cross-sectional dimensions done.
In FIGS. 12 and 13, the same separating device 29 as shown in FIGS. 10 and 11 is shown, but instead of an inner cup 102 having a circular cross section, here an inner cup 102 having a non-circular cross-section, namely a substantially quadrangular cross-section is shown.
The basic structure of the separating device 29 is selected to be the same as previously described in FIGS. 10 and 11 and comprises four pieces of separating elements 30, which are respectively arranged on the pivoting levers 42 and 43. The respective associated pivoting levers 42 and 43 for one of the separating element pairs 40 or 41 may be mounted on the diametrically opposite pivot axes 44 or 45. These two pivot axes 44 and 45 are each arranged in the previously described fixed distances 46, 47 spaced from the common conveying axis 33 or the longitudinal axis 104.
The two separating element pairs 40 and 41 are arranged in the diagonal direction relative to each other with respect to corner regions of the inner cup 102. The adjustment for destacking of different container cross sections is in turn carried out by a kind of scissor movement of the respectively associated pivoting lever 42 or 43 and the associated increase or decrease of the enclosed by the associated pivoting levers 42 or 43 angle. The respective adjustment of the respective associated pivot lever 42 or 43 is uniform and preferably centric with respect to the common conveying axis 33 or the longitudinal axis 104th
FIG. 14 shows another embodiment of the preparation station 25, which may be independent of itself, and in particular the adhesive application station D4 with the step of adhesive application D4, wherein the same reference numerals or component designations as in the preceding FIGS to 11 are used. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 11 or reference.
As already described in FIGS. 3 and 4, the first working step D1 takes place in the preparation station 25 in the separating station D1 in which a piece of the same is stacked from a stack of blanks. This takes place in a predetermined working cycle, whereby the individual blanks are further conveyed to one another at a predetermined conveying distance 50 from the conveyor belts 10 to the feed carriage 18. The preparation station 25 shown in FIG. 14 basically corresponds in its structure to the structure as described and shown in the two FIGS. 3 and 4. The conveying distance 50 is calculated as the quotient of the number of cut pieces stacked by the separating station D1 and the speed of the conveyor belts 10.
Subsequent to the separating station D1 with the first working step D1, the prebending station D2 can be provided with the step of pre-bending D2 of the later seam area and / or also the heating station D3 with the third working step D3.
The adhesive application station D4 with the step of adhesive application D4 can be designed differently from the previously described adhesive application station D4. It is provided here that in turn at least one first nozzle 13 and at least one second nozzle 17 are provided or arranged for the adhesive application D4. This creates the possibility of being able to apply different adhesives to the longitudinal edge area of the blanks provided in the seam area to be formed.
In contrast to the embodiment in FIGS. 3 and 4, the at least one first nozzle 13 and the at least one second nozzle 17 are arranged spaced apart from each other in the conveying direction of the blanks along the conveyor belts 10. Of the
Adhesive application D4 also takes place in an equivalent manner at the same time, but on blanks located immediately after one another in the conveying direction in the adhesive application station D4 and likewise spaced from each other. As described above, the individual blanks are arranged at a distance from one another in the predetermined conveying distance 50. Thus, the at least one first nozzle 13 with respect to the at least one second nozzle 17 in the predetermined conveying distance 50 are spaced from each other or spaced apart. The conveying distance 50 is aligned in the direction of the longitudinal extent of the conveying path of the conveying means, in particular of the conveyor belts 10.
Furthermore, it is shown here that the at least one first nozzle 13 and the at least one second nozzle 17 are arranged on a common holding arm 51. The holding arm 51 has a longitudinal extent, which is selected to extend in a parallel direction with respect to the conveying direction. The holding arm 51 is adjustably guided in the parallel direction with respect to the conveying plane 15. The transverse adjustment of the holding arm 51 with the at least two nozzles 13 and 17 is preferably carried out in a vertical direction with respect to the conveying direction of the settlement. This transverse adjustment of the two nozzles 13 and 17 shown here for applying the adhesive takes place simultaneously and coordinated with the conveying movement of the unwinds. As a result, at correspondingly matched movement speeds relative to each other (feed rate of the unwinds by the transport speed of the conveyor belts 10 and the rectilinear adjustment of the support arm 51 with the respective adhesive application heads 23 with their nozzles 13, 17) between the support arm 51 and the unwinds or the blanks respectively at least one preferably continuously trained first adhesive bead 16 and at the same time also the at least one second bead of adhesive 24 or the at least one further bead of adhesive 24 are applied. However, this always on different, directly in the conveying direction successively arranged settlements or blanks.
Thus, it is shown here that the at least one first adhesive bead 16 in a first partial application station D4-1 of the adhesive application station D4 and the at least one second adhesive bead 24 in a second partial application station D4-2 of the adhesive application station D4 are applied. The preferably straight transverse adjustment of the holding arm 51 can by means of an unspecified adjusting mechanism, such as. an eccentric drive and a lever assembly standing in drive connection, take place.
With the at least one first nozzle 13, e.g. the hot glue or hotmelt and with the at least one second nozzle 17 of the white glue are each applied in the form of a bead of adhesive. But it would also be a mutual swap of white glue and hot glue possible. Preferably, however, the hot glue is applied only briefly and immediately before the transfer to the first holding device carrier 3, so as to keep the cooling time of the same as short as possible. The white glue or the first adhesive bead 16 formed therefrom is preferably applied closer to the outer longitudinal edge than the second adhesive bead 24.
FIGS. 15 and 16 show a further embodiment of the transfer station 6, which may be independent of itself, for transferring A4, B1 of a finished outer shell 101 from a first holding device 2 to a second holding device 4. Component designations as used in the preceding Figs. 1 to 14. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 14 or reference.
The transfer station 6 can be used both in that machine 1, as shown and described in FIG. 2, and in that machine 1, as shown and described in FIG. 8.
In the case of outer shells 101 with a round cross-section, the auxiliary unit 52 described below is not absolutely necessary, but can preferably be used with already prefabricated outer shells 101 having a non-circular, in particular a polygonal cross-section.
The auxiliary unit 52 serves or is designed to make the insertion and the reception of the individually prepared outer shells 101 from the blanks or the unwindments into the second holding devices 4 more secure. In particular in the case of non-circular cross-sections, buckling may occur in the longitudinal regions of the outer sheaths 101 on the side or direction away from the center, whereby the insertion into the mold cavity of the second holding devices 4 formed by the sleeves, rings or hollow mandrels is no longer possible.
Thus, the auxiliary unit 52 may have at least two in the transfer direction opposite each other arranged transfer elements 53, which are in drive connection with a drive unit not shown in detail. The opposite of the two transfer elements 53 refers to a plane aligned in the vertical direction with respect to the transfer direction. The at least two transfer elements 53 have a preferably opposite direction of drive or direction of rotation, as shown by arrows. Each of the transfer elements 53 may be e.g. be designed as a wave. The outer longitudinal profile or the axial cross-sectional shape of the transfer elements 53 can be modeled on a partial section of the cross-sectional shape of the outer shell 101 to be produced. In addition, at least one element which increases the frictional effect on the outer shells 101, in particular an O-ring or even a coating, may be arranged or provided on the outer circumference of the transfer elements 53. Regardless, it would also be possible to form the transfer element by one or more circumferential bands or belts. This can be seen in Übergaberichtung, a longer secured transfer path can be achieved.
In order to be able to carry out an adaptation to different cross-sectional dimensions of external casings 101 to be transferred, an adjusting movement oriented in the vertical direction with respect to the transfer direction can be possible. Preferably, the mutual adjustment of the transfer elements 53 takes place centrally with respect to the transfer direction and thus also centrally with respect to the respective second holding device 4.
FIG. 17 shows a further embodiment of a separating station C1, which is possibly independent of itself, wherein the same reference numerals or component designations are again used for the same parts as in the preceding FIGS. 1 to 16. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 16 or reference.
The separating station C1 is used for separating inner cups 102 from a stack of inner cups 102 provided and, in this exemplary embodiment, in addition to the separating device 29 also comprises a feed device 54 indicated in simplified form. The feed device 54 is in the form of a paternoster and has inner cups 102 for each stack to be fed a running in a horizontal orientation transport floor 55. The longitudinal extent of the individual transport bottoms 55 corresponds to at least usual staple lengths. In a feed region 56 arranged closer to the bottom, the loading of a transport floor 55 of the feed device 54 takes place with one of the inner beaker stacks. This stack of inner cups 102 is in particular promoted step by step into a floor-distant transfer area 57 and there pivoted from its horizontal position by means of a pivoting device 58 in a vertical position. The pivoting device 58 is indicated schematically simplified only with a circular arc.
In this case, a so-called head-over position for the stack, in particular the inner cup stack, is preferably selected, in which the edge strip 103 and thus the open cup ends of the inner cup 102 are located at the bottom and the cup bottoms are arranged at the top. By this underlying orientation of the cup rim or the edge strip 103, these are also the separating elements 30 facing and can be used by them for separation with. The thus provided stack of inner cups 102 is further guided in the tube 32 down to the singulation elements 30 and from these preferably cyclically each an inner cup 102 delivered individually.
In all of the preparation stations 25 described above, the blank or the unwinding is planar surface for the formation of outer shells 101 to the first
Holding devices 2 of the first holding device carrier 3 provided or handed over. In order to carry out the transfer of ready-formed outer shells 101 from the first holding devices 2 of the first holding device carrier 3 to respective second holding devices 4 of the second holding device carrier 5, a short standstill time is to be maintained. Therefore, the circulation of the holding device carrier 3 and 5 is not carried out with a constant, uniform rotational speed, but in a clocked stepwise circulation. This means that in a power stroke, starting from standstill, an adjustment of the holding device carrier 3 and 5 takes place in each case by a predetermined angle of rotation and the power stroke ends with a new standstill. Thus, at the beginning of the working cycle an accelerated movement takes place, which is braked again at the end of the cycle to a speed with the value zero.
As shown in FIG. 4, one of the first holding devices 2 of the first holding device carrier 3 is located just above the blank or take-up provided by the feed carriage 18 and is further rotated from there by a predetermined pivoting angle until the further first holding device following directly in the direction of rotation 2 arrived at the same place and is located there. Upon reaching the standstill, the transfer of the outer shell 101 described above with the transfer step A4 - B1 takes place at the transfer station A4 or 6.
As a result of the flat starting position of the blank or the unwinding and the beginning of the winding process to the first holder 2, there is a rapid pivoting movement of the two outer ends of the blank o-the settlement towards the respective first holding device 2. Of the two outside Ends, the seam area of the wound outer shell 101 is subsequently formed. During this rapid pivoting movement, the adhesive applied beforehand in the longitudinal edge region may be thrown away. This can lead to an incomplete or defective adhesive bond. Furthermore, however, the machine 1 or parts of the same can be contaminated by the thrown off adhesive. Since such contamination by adhesive can quickly lead to malfunctions and malfunctions, they would be minimized or even avoided by different measures or additional steps with dedicated devices or equipment parts.
It is also shown in FIG. 18 that the blank, which has a flat orientation at first, or the unwinding in the region of the feed carriage 18 of the preparation station 25 can be preformed to an approximately U-shaped cross-section. For this purpose, the feed carriage 18 in its transverse to the conveying direction spaced from each other arranged right and left side portion each have a holding and pivoting arrangement 59. The holding and swiveling arrangements 59 can each have a pivotally mounted flattening plate 60. The previously described guide rails 11, the stop blocks 12 and also the suction openings 20 can be provided or arranged on these flat plates 60.
The two holding and swiveling arrangements 59 can be swung up from a position parallel to the conveying plane 15 into an angular position toward the first holding devices 2. The two pivot axes have a nearly parallel or a completely parallel alignment with respect to the conveying direction of the conveyor belts 10. On the presentation of drive means for carrying out the pivoting or adjusting movements has been omitted for the sake of clarity. The preformed position of the blank or the development and the holding and pivoting arrangements 59 is indicated in dashed lines.
In addition or independently of this, it would also be possible to move the entire feed carriage 18 into a lifting movement opposite thereto with respect to the rotational downward movement of the first holding devices 2 of the first holding device carrier 3. This raising movement can take place in a vertical orientation with respect to the conveying plane 15, as indicated by an arrow on the left edge of the feed carriage 18.
To the whip effect described above at least one of the longitudinal edges, in particular in that in which the adhesive is applied, and the feed movement of the first holder 2 towards the blank carrying feed carriage 18 could be kept very low until the first contact and only then Angular velocity and thus the rotational speed can be increased. However, this has the consequence that the cycle speed is reduced and the efficiency in the number of attached cups 100 per unit time decreases.
The embodiments show possible embodiments, it being noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but also various combinations of the individual embodiments are mutually possible and this variation possibility due to the teaching of technical action by representational invention in Can the expert working in this technical field.
The scope of protection is determined by the claims. However, the description and drawings are to be considered to interpret the claims. Individual features or combinations of features from the illustrated and described different embodiments may represent for themselves inventive solutions. The task underlying the independent inventive solutions can be taken from the description.
