Coupling device, lifting arrangement and adjustment method for a coupling device
The present invention relates to a coupling device with at least one upper part of the device and at least one lower part of the device, the upper part of the device and the lower part of the device being releasably connectable, as well as a lifting arrangement with a lifting device and an object to be lifted, and a method for adjusting a coupling device.
Lifting devices are used in a wide variety of variants and in a wide variety of applications. Lifting devices can be in the form of cranes, e.g. as a gantry crane, overhead crane, tower crane, mobile crane etc., or also in the form of handling devices such as Robots. Many different objects can be manipulated or moved and transported from one place to another. These objects can also have a wide variety of forms, from very light, small components to very heavy objects, such as Pressing tools for steel bodies for vehicles or the like. Lifting devices can be operated manually by people, but are also increasingly being used in automated processes, for example in the production processes of vehicles. The connection of the objects to be lifted to the lifting device plays a crucial role, particularly in automated processes, in which any positional deviations between lifting device and object, unlike in processes controlled by humans, are not performed by the user, e.g. an experienced crane operator can be compensated. Therefore, in automated manipulation processes, it is necessary to coordinate the position of the lifting device and the position of the object to be lifted very precisely in order to ensure that lifting operations are always safe and reproducible and thus ensure trouble-free operation. This usually requires an exact adjustment of the lifting device, which can be quite complex in practice. To increase the profitability of a production process, e.g. the cycle time of a processing station can be shortened, which is why it is often necessary or desirable to carry out certain manipulation processes in ever shorter times. This leads to the demand for ever higher accelerations and speeds of lifting devices, which in turn leads to higher loads on the lifting device, in particular to higher loads in the area of the coupling of the object to be lifted to the lifting device.
Document AT 517515 A2 shows, for example, a flexible joining system for vehicle bodies with a joining station and a stenter. In order to be able to process different body models in a joining station, different clamping frames must be provided by a lifting device. In this case the lifting device is through / 25 1
TM-3902 AT designed a gantry crane that can pick up and move the stenter at a central point of the stenter. The disadvantage here is that the connection between the tenter frame and the gantry crane is made only by means of a single coupling element which is arranged centrally on the tenter frame. Due to this design, no high accelerations or decelerations of the gantry crane can take place, since the high forces and torques occurring in the coupling element can only be insufficiently absorbed and diverted into the gantry crane. Or the coupling element must be dimensioned very large, which would also be disadvantageous. In addition, the point of application of the lifting device on the tenter frame is chosen very centrally in order not to impress static torques in the coupling element due to the weight of the tenter frame. A point of engagement of the lifting device located further outside on the clamping frame would, under certain circumstances, lead to impermissibly high loads and damage to the coupling element when a single coupling element is arranged, since a single coupling element can only insufficiently absorb torques.
Accordingly, it is the object of the invention to provide a coupling device which is suitable for coupling a lifting device to an object to be lifted in a lifting arrangement and with which the disadvantages of the prior art are eliminated. In particular, an easily adjustable coupling device is to be created which can be used flexibly on a wide variety of lifting devices and with the aid of which it should be possible to manipulate large loads with dynamic movement sequences.
According to the invention, the object is achieved in that the coupling device has at least two coupling elements, each with a coupling element upper part and a coupling element lower part, the at least two coupling element upper parts being arranged fixed on the upper part of the device and the at least two coupling element lower parts being arranged on the lower part of the device, at least one lower coupling element being adjustable relative to the lower part of the device and is detachably arranged on the lower part of the device. The arrangement of several coupling elements on the one hand makes it possible to lift and move larger loads, and on the other hand the high acceleration forces and moments due to dynamic movement sequences of the lifting device can be better absorbed and diverted into the lifting device.
It is advantageous if the device has at least four coupling elements. As a result, either the permissible load can be increased further or more compact coupling elements can be used with the same permissible load. In particular, by arranging at least four coupling elements, the acceleration forces or moments can be better absorbed by the coupling device in the case of multidimensional dynamic movement sequences.

If the coupling elements can be operated pneumatically, electrically or hydraulically, standard components available on the open market can be used and a standard energy supply system (compressed air system, power supply system, hydraulic system) can be used to open and release the coupling elements.
According to a particularly advantageous embodiment of the invention, a centering element is arranged on the upper part of the device and a centering mark is provided on the lower part of the device, the centering element and centering mark interacting to center the upper part of the device on the lower part of the device. This enables simple centering of the upper part of the device on the lower part of the device to adjust the coupling device.
If at least one adjusting element for adjusting the at least one coupling element lower part is arranged on the lower part of the device, a simple, easily metered and reproducible adjustment possibility for the lower coupling element parts is created, which enables a quick and easy adjustment of the coupling device according to the invention.
According to the invention, to achieve the object, the coupling device has at least two coupling elements, each with a coupling element upper part and a coupling element lower part, the at least two coupling element upper parts being arranged in a fixed position on the upper part of the device and the at least two coupling element lower parts being arranged on the lower part of the device, at least one lower coupling element relative to the lower part of the device is adjustable and detachably arranged on the lower part of the device, the upper part of the device being arranged fixed on the lifting device and the lower part of the device being fixed on the object to be lifted. This creates a lifting arrangement for lifting and manipulating loads in dynamic movements.
The lifting device is preferably a crane, in particular a gantry crane. This results in a wide range of applications, for example in production plants.
If the object to be lifted is a clamping frame, the coupling device or the lifting arrangement can be used in a joining system for the production of vehicle bodies.
The coupling device preferably has at least 4 coupling elements. As a result, either the permissible load can be increased further or more compact coupling elements can be used with the same permissible load. In particular, by arranging at least 4 coupling elements, the acceleration forces or moments can be better absorbed by the coupling device in the case of multidimensional dynamic movement sequences.

If the coupling elements can be actuated pneumatically, electrically or hydraulically, standard components available on the open market can be used and a standard energy supply system (compressed air system, power network, hydraulic system) can be used to open and release the coupling elements.
According to an advantageous embodiment of the invention, the upper part of the device has a centering element and the lower part of the device has a centering mark, the centering element and the centering mark interacting to center the upper part of the device on the lower part of the device. This enables simple centering of the upper part of the device on the lower part of the device to adjust the coupling device.
If at least one adjusting element for adjusting the at least one adjustable coupling element lower part is arranged on the lower part of the device, a simple, easily metered and reproducible adjustment possibility for the lower coupling element is created, which enables a quick and easy adjustment of the coupling device according to the invention.
According to an adjustment method according to the invention, the coupling device has at least two coupling elements, each with a coupling element upper part and a coupling element lower part, the at least two coupling element upper parts being arranged in a fixed position on the upper part of the device and the at least two coupling element lower parts being arranged on the lower part of the device, at least one lower coupling element being adjustable and adjustable relative to the lower part of the device is detachably arranged on the lower part of the device and first the upper part of the device is centered on the lower part of the device, whereupon the at least one adjustable coupling element lower part is detached from the lower part of the device and is adjusted, so that the at least one adjustable coupling element lower part can be coupled to the corresponding coupling element upper part, whereupon the at least one adjustable coupling element lower part on the device is fixed. This simple method makes it possible to synchronize the upper part of the device connected to the lifting device with the lower part of the device which is fixedly arranged on the object. This ensures that all lower coupling element parts are aligned in such a way that they can be securely coupled to their corresponding coupling element upper parts during each coupling process.
It is advantageous if the upper part of the device is centered on a centering mark arranged on the lower part of the device by means of a centering element which can be arranged on the upper part of the device. This simplifies the implementation of the method, since a simple centering possibility is created by positioning the lifting device in this way
TM-3902 AT that the centering element arranged on the upper part of the device corresponds to the centering mark arranged on the lower part of the device.
According to a further advantageous embodiment of the method according to the invention, the at least one adjustable coupling element lower part is adjusted by means of the at least one adjusting element arranged on the lower part of the device. This makes it possible to adjust the lower part of the coupling element in a very simple, easily accessible and precise manner, and an adjustment possibility that is easily reproducible for several adjustment processes is created.
According to a particularly preferred embodiment of the method, a centering sleeve upper part is slidably arranged on at least one coupling element upper part and a centering sleeve lower part which corresponds to the centering sleeve upper part is arranged on the at least one corresponding coupling element lower part, whereupon the at least one adjustable coupling element lower part is adjusted until the centering sleeve upper part is brought into contact solely due to the force of gravity corresponding lower part of the centering sleeve slides. This makes it possible to match the coupling element upper parts and the coupling element lower part very precisely to one another in a few very simple steps.
The upper part of the device is preferably arranged in a fixed position on a lifting device, in particular on a gantry crane, and the lower part of the device is arranged in a fixed position on an object, in particular on a clamping frame. This means that the adjustment method can also be used in production systems such as Joining systems for vehicle bodies can be used.
The present invention is explained in more detail below with reference to FIGS. 1 to 3, which show exemplary, schematic and non-limiting advantageous embodiments of the invention. It shows
1 shows the coupling device according to the invention in a preferred embodiment
2 shows the lifting system according to the invention with a preferred embodiment of the coupling device when used in a joining system
3a to 3c show sections of a coupling device when carrying out the adjustment method according to the invention.
1 shows a coupling device 1 according to the invention, which has at least one upper device part 2 and one lower device part 3. The terms "upper part" and "lower part" do not denote a specific orientation or arrangement of the two parts, but only serve to differentiate. The upper device part 2 can be arranged in a stationary manner on a lifting device 19 by means of an adapter part 7 and the lower device part 3 can be arranged in a stationary manner on an object 20 by means of a connecting part 8/25 5 '
TM-3902 AT (for reasons of clarity, the lifting device 19 and object 20 are not shown in Fig.1), whereby the arrangement could also be reversed. The adapter part 7 and the connecting part 8 can be adapted to the circumstances of the respective arrangement. The upper device part 2 and the lower device part 3 are advantageously made of a high-strength, mechanically machinable material, for example of steel. The device upper part 2 is preferably designed as a welded construction, but other embodiments would also be conceivable, such as a built structure that can consist of individual components that are detachably connected to each other. The specific configuration of the upper part 2 of the device must in any case be designed in such a way that the absorption of the forces and torques to be expected from the lower part 3 of the device and the transfer thereof to the lifting device 19 can be reliably ensured.
For the detachable coupling of the upper device part 2 to the lower device part 3, the coupling device 1 has at least two coupling elements 4, wherein a coupling element 4 in turn has an upper coupling element part 5 and a lower coupling element part 6. By arranging at least two coupling elements 4, higher loads can be lifted or moved with the lifting device 19 and more dynamic movement processes can be carried out with the lifting device 19, since the forces and torques which arise during acceleration and deceleration processes of the lifting device 19 are better can be picked up by the coupling device 1 according to the invention and can be derived into the lifting device 19.
According to the invention, the at least two coupling element upper parts 5 (the at least two coupling elements 4) are arranged in a fixed position on the device upper part 2 and the associated at least two coupling element lower parts 6 are arranged on the device lower part 3, at least one coupling element lower part 6 being adjustable relative to the device lower part 3 and detachably arranged on the device lower part 3. It is also possible for a first coupling element lower part 6 to be fixed, that is to say not adjustable, on the lower device part 3 and for a second coupling element lower part 6 to be adjustable on the lower device part 3. The at least one adjustable coupling element lower part 6 is preferably detachably fastened on a flat adjustment surface 9 of the lower device part 3 by means of fastening elements 10, such as screws. The adjustment surface 9 can be a flat surface, but it would also be conceivable that the coupling element lower part 6 is adjustably arranged in recesses, grooves, rails or the like, it is important that the adjustable coupling element lower part 6 is adjustable relative to the device lower part 3. Adjustable means in this context that the adjustable coupling element lower part can be moved relative to the device 6 lower part 3 in at least one direction, preferably in two directions, particularly preferably in the direction of two mutually orthogonal / 25 6 '
TM-3902 AT
Axes as symbolized in Fig.1 by the X axis and the Y axis. This adjustment possibility is necessary in order to center the adjustable coupling element lower part 6 for adjustment with the corresponding coupling element upper part 5, so that a secure coupling can be ensured or a coupling is possible at all. Once the positions of the coupling elements 4 have been coordinated with one another, coupling operations that can be repeated as desired can be carried out without further adjustment measures, and a constant, secure coupling of the coupling element upper parts 5 and the corresponding coupling element lower parts 6 can be ensured.
Although it would be conceivable to dispense with the adjustability of the at least one coupling element lower part 6 according to the invention and to arrange the coupling element lower parts 6 precisely and fixedly on the device lower part 3 (analogously to the coupling element upper parts 5 on the device upper part 2), an exact position coordination of the coupling elements 4 would be necessary for a safe Coupling process is required, due to component and manufacturing tolerances very difficult to achieve or this would only be feasible using precision manufacturing, which would mean a very high cost.
In the case of 2-dimensional movement sequences of the lifting device 19, for example lifting and lowering in the direction of the Z axis and moving for example in the direction of an axis (Y axis or X axis), it could be sufficient to provide two coupling elements 4 on the coupling device 1 because the dynamic forces act in particular in the direction of the Z-axis and the dynamic torques resulting from acceleration processes (which of course also includes a deceleration) of the lifting device 19 act in particular only about an axis. When the lifting device 19 is moved in the ZY plane, a torque M x about the X axis would result, for example, during acceleration processes, when the lifting device 19 was moved in the ZX plane, a torque M y about the Y axis would result. Often, however, a 3-dimensional dynamic movement of the lifting device 19 takes place, for example lifting and lowering in the direction of the Z axis and moving in the direction of the X axis and the Y axis. As a result, in addition to the forces predominantly in the direction of the Z axis, both torques M x about the X axis and torques M y about the Y axis arise. According to an advantageous embodiment of the coupling device 1 according to the invention, at least four coupling elements 4 are therefore provided on the coupling device 1, as a result of which the forces and torques which result from the dynamic movement process of the lifting device 19 are better absorbed by the coupling device 1 and derived into the lifting device 19 can. Preferably, all four coupling element lower parts 6 are adjustably detachably arranged on the device lower part 3, as shown in FIG. 1, but it would also be conceivable to make less than four coupling element lower parts 6 adjustable. For example, the centering of the upper device part 2 on the lower device part 3 could be done by means of a stationary on / 25 7 '
TM-3902 AT
Device upper part 2 arranged coupling element upper part 5 and a coupling element lower part 6 arranged stationary on the device lower part 3 can be carried out, the remaining coupling element lower parts 6 being adjustable so as to be adaptable to their corresponding coupling element upper parts 5 arranged fixed on the device upper part 2. However, any other combinations of fixed and adjustable coupling element lower parts 6 are also conceivable.
An additional advantage when arranging a plurality of coupling elements 4 on the coupling device 1 can also be seen in increasing the reliability of the coupling device 1, in particular if coupling elements 4 are designed redundantly. An arrangement of several coupling elements 4 could, however, also lead to an increase in occupational safety, for example if objects 20 are moved over people by means of a lifting device 19 (e.g. a gantry crane).
A coupling element 4, and the parts thereof, can in principle be of any design. It is essential that a coupling element upper part 5 and a coupling element upper part 5 are detachable from one another and that the forces and torques to be expected can thus be absorbed. The detachability of coupling element upper part 5 and coupling element upper part 5 is preferably controllable and preferably comprises a coupling drive in order to couple or detach the coupling element upper part 5 and the coupling element upper part 5. In principle, any drive is conceivable for this, in particular a hydraulic, pneumatic, electrical, electromagnetic, etc. drive. Coupling elements 4 of this type are also commercially available in various designs.
According to a particularly advantageous embodiment of the coupling device 1 according to the invention, the coupling elements 4 can be actuated pneumatically and are standard components, such as, for example, clamping units from CyTec cylinder technology. To connect the coupling elements 4 to the coupling drive, e.g. Compressed air connections 14 can be arranged on the coupling element upper parts 5. One advantage of the pneumatic actuation is that an existing compressed air supply system can be used to actuate the coupling elements 4. Compressed air supply systems of this type are widespread and belong, for example, to standard equipment in production and manufacturing systems. Another advantage is that in the event of a leakage of the coupling elements 4, only air escapes and no liquid medium can escape, as is the case, for example, with hydraulically actuable coupling elements 4, so that there is no contamination of the coupling device 1, of the object 20 to be moved or of negative influences People through contact with eg Hydraulic fluid can come.
A further advantage of the pneumatic actuation of the coupling elements 4 is that the security / 25 8 ', which varies according to the field of application of the coupling device 1
TM-3902 AT
Regulations can be met without much effort. If e.g. redundancy of the actuation of the coupling elements 4 is required, two independent pneumatic control circuits can be used. If necessary, e.g. encapsulated valves are used or a redundant query can be implemented whether e.g. a coupling element 4 is coupled or not. The pneumatic coupling elements 4 are advantageously designed such that if the supply energy or the compressed air fails, the coupling elements do not open, i.e. no decoupling of coupling element upper part 5 and coupling element lower part 6. This ensures that an object 20 does not suddenly detach itself from the lifting device 19 or the lower device part 3 arranged on the object 20 does not suddenly detach from the upper device part 2 in the event of a power failure.
Despite the advantages of the pneumatic actuation of the coupling elements 4, other forms of actuation are also conceivable, e.g. hydraulic, electrical or magnetic actuation, whereby of course similar or identical safety-relevant features can also be realized with these forms of actuation.
It is advantageous if the upper device part 2 has a centering element 11 and the lower device part 3 has a centering mark 12. The centering element 11 can, however, also be arranged on the upper part of the device 2 only for the purpose of adjustment and can be removed in normal operation. This enables a simple possibility of centering the upper device part 2 on the lower device part 3 for the purpose of adjusting the coupling element lower parts 6. The centering element 11 can, for example, be designed as an elongated centering rod which is attached to the upper part of the device at its first end and which has a centering tip at its second end which is positioned on a centering mark 12 for the purpose of centering the upper part of the device 2 with the lower part 3 of the device, which is arranged on the lower part 3 of the device. The centering mark 12 can e.g. in the form of a cross by mechanical processing on the adjustment surface 9 of the lower device part 3. For example, the centering element 11 could also be designed as a cylindrical rod, which is arranged on the device upper part 2, and the centering marker 12 could be designed as a cylindrical bore in the device lower part 3, the device upper part 2 being positioned so that the device upper part 2 is centered with the device lower part 3 the cylindrical rod fits into the cylindrical bore. However, any other combination of centering element 11 and centering marker 12 is also conceivable.
It is particularly advantageous if at least one adjusting element 13 for adjusting the at least one adjustable coupling element lower part 6 is arranged on the lower device part 3. As a result, the above-described adjustment of the at least one adjustable coupling element lower part 6 or an adaptation to the corresponding coupling element / 25
TM-3902 AT top part 5 can be carried out very easily and precisely. It is advantageous if two corresponding adjustment elements 13 are arranged on the lower device part 3 for each adjustable coupling element lower part 6. For example, a first adjustment element 13a can be arranged for an adjustment of the coupling element lower part 6 in the direction of the X-axis and a second adjustment element 13b can be arranged for an adjustment of the coupling element lower part 6 in the direction of the Y-axis, but of course there would also be a different number and different positions of adjustment elements 13 conceivable and other adjustment directions would also be possible. Adjustment elements 13 can e.g. be designed as jaws 15, which are either fixed or releasably connected to the lower device part 3. In this context, fixed means e.g. welded, glued, soldered etc. to the lower device part 3 or made in one piece with the lower device part 3, e.g. as a cast or milled part. In the embodiment variant according to FIG. 1, the jaws 15 are e.g. attached to the lower part 3 of the device by means of detachable fastening elements 16. Detachable fastening elements 16 can be, for example, screws, bolts, etc. For adjusting the coupling element lower parts 6, spacer plates of a certain thickness can be arranged, for example, between an adjusting element 13 and a coupling element lower part 6. The desired position of the adjustable coupling element lower part 6 can be adjusted relative to the lower device part 3 by arranging different spacing plates (also several spacing plates). However, actuating elements 17 can also be arranged in the adjusting elements 13. An actuator 17 may e.g. be a screw which is screwed into a thread arranged in the adjusting element 13 or jaws 15 and the end of which is in contact with a lower coupling element 6. When the screw is rotated, there is an axial displacement of the screw and consequently a displacement of the corresponding lower coupling element part 6. Adjustment elements 13 and actuating elements 17 can also be designed in any other shapes and combinations, it is only important that an adjustment of the coupling element lower parts 6 is effected.
2 shows the coupling device 1 according to the invention in a preferred embodiment in a preferred application in a joining station 18 of a production process for the production of vehicle bodies. The lifting device 19 is preferably designed as a gantry crane 21, in particular as an automated gantry crane, and the object 20 is designed as a tensioning frame 22 for receiving and tensioning body parts. The coupling device 1 is fixedly connected to the movable part of the gantry crane 21 via the adapter part 7 of the upper device part 2 and fixed to the clamping frame 22 by means of the connecting part 8 of the lower device part 3. The connection of the upper device part 2 to the lifting device 19 embodied as a gantry crane 21 in FIG. 2 is preferably designed to be detachable, for example with screw connections. The connection could also be made by any other type of connection, e.g. through sweat
TM-3902 AT essen, riveting, gluing etc. The same applies to the connection of the lower part 3 of the object 20, which is shown in Figure 2 as a clamping frame 22. Detachable screw connections are preferably used, as a result of which the coupling device 1 can be used flexibly and can be removed from the lifting device 19 for repair and maintenance purposes. In the position shown in FIG. 2, the upper device part 2 and the lower device part 3 are coupled to one another by means of the coupling elements 4. By loosening the coupling elements 4, the object 20 can be separated from the lifting device 19. Due to the precise adjustment of the coupling elements 4, the lifting device 19 can move to the position of the released object 20 again exactly and pick up the object again by coupling the coupling elements 4 again.
In the embodiment of the coupling device 1 in use in a joining station 18 according to FIG. 2, four pneumatic clamping units from CyTec cylinder technology are arranged on the coupling device 1 as coupling elements 4. These clamping units are particularly advantageous since they have a certain permissible tolerance both with regard to the angular accuracy and with regard to the positional accuracy. For example, the clamping units arranged as coupling elements 4 in the joining station 18 according to FIG. 2 are designed in a size in which the permissible angular tolerance is 2 ° and the permissible radial tolerance is 1.5 mm, the angular tolerance being based on an angular deviation of the longitudinal axis of a lower coupling element 6 The longitudinal axis of an upper coupling element 5 is related and the radial tolerance is related to a positional deviation of the longitudinal axis of a lower coupling element 6 from the longitudinal axis of an upper coupling element part in the X-Y plane according to FIG. The adjustment process, i.e. the adaptation of the lower device part 3 to the upper device part 2 is facilitated since the coupling element lower parts 6 on the lower device part 3 are not complete, i.e. do not have to be positioned to the nearest tenth of a millimeter in order to be able to be coupled with their corresponding coupling element upper parts 5. In addition, an angular tolerance enables an object 20, e.g. a clamping frame 22, even with smaller angular deviations, e.g. come about due to poor positioning of the tenter frame 22 on a tenter frame carrier, or which result from manufacturing or component tolerances of the coupling device 1 or the tenter frame 22. This tolerance information is of course to be understood only as an example, since it depends on the type and design and in particular the size of the coupling elements 4. Depending on the area of application, required accuracy and available standard components, coupling elements 4 with different tolerances can be used.
In the embodiment of the coupling device according to FIG. 2, the lower device part 3 is arranged at one end of the tensioning frame 22, ie not in the center of gravity S of the tensioning frame 22 in the Y direction, but at a distance y s . This makes it so
-1112 / 25
TM-3902 AT probably when the gantry crane 21 is at a standstill (in the air without contact of the tenter frame 22, for example on a tenter frame carrier) as well as when lifting / lowering or 1-dimensional movement of the portal crane 21 in the direction of the Z-axis in comparison to a central one Arrangement of the lower device part 3 on the clamping frame 22, high torques M x about the X axis are impressed in the coupling device 1. The same could also apply to torques M y if the lower device part 3 were located in the direction of the X axis from the center of gravity S of the clamping frame 22 (not shown in FIG. 2). Because of the static loads mentioned due to the weight of the object 20 or clamping frame 22 and the loads caused by 3-dimensional dynamic movement processes of the gantry crane 21, the invention provides that at least two coupling elements 4 are provided on the coupling device 1, in particular it is advantageous if at least four Coupling elements 4 are provided on the coupling device 1.
The coupling device 1 according to the invention is, however, not limited to the use in joining systems according to FIG. 2, but all other applications are also conceivable, in which particularly large loads are moved and dynamic movement sequences are carried out, e.g. in the area of goods handling, etc. The lifting device 19 is not limited to a gantry crane 21 but can be designed as any other lifting device 19, for example as a robot or any other type of crane.
3a to 3c show sections of a coupling device 1 for coupling a lifting device 19, as described with reference to FIG. 1, to an object 20 when carrying out an adjustment method according to the invention (for reasons of clarity, the lifting device 19 , the object 20 to be lifted and some elements of the coupling device not shown). According to the invention, the device upper part 2 is first pre-centered on the device lower part 3 by positioning the lifting device 19, this centering preferably takes place by means of a centering element 11 which can be arranged on the device upper part 2. For the purpose of easier centering of the device upper part 2 on the device lower part 3, the lifting device 19 with the device upper part arranged thereon 2 positioned so that the centering element 11 coincides with a centering mark 12 which can be arranged or provided on the lower part 3 of the device. After centering has been carried out, at least one, preferably each, coupling element lower part 6 is detached and adjusted from the device lower part 3, so that each coupling element lower part 6 can be coupled to the corresponding coupling element upper part 5. If e.g. the coupling element lower parts 6 by means of fastening elements 10, e.g. Screws are detachably arranged on the lower part 3 of the device, the fastening elements 10 can be loosened and the lower coupling element parts 6 can be adjusted accordingly. The coupling element lower parts 6 can be adjusted, for example, by hand, more preferably
-1213 / 25
TM-3902 AT, however, adjustment elements 13 for adjusting the coupling element lower parts 6 are arranged on the lower device part 3. With the aid of these adjustment elements 13, a simpler, more precise and reproducible adjustment of the coupling element lower parts 6 can be carried out. Preferably, two adjusting elements 13 are arranged on the lower device part 3 for each coupling element lower part 6, preferably a first adjusting element 13a for the adjustment of the coupling element lower part 6 in a first direction and a second adjusting element 13b for the adjustment of the coupling element lower part 6 in a second direction on the lower device part 3. The two directions in which a coupling element lower part 6 can be adjusted are particularly preferred, two orthogonal axes, as indicated in FIG. 3a by the X-axis and Y-axis. For example, actuating elements 17 such as e.g. Screws may be provided in the adjustment elements 13. For example, an axial displacement of a coupling element lower part 6 could be achieved by turning the screw. However, e.g. Different spacer plates of different thicknesses are arranged between the adjusting elements 13 and the coupling element lower parts 6 for setting the desired position of the coupling element lower part 6 relative to the device lower part 3. Adjusting elements 13 and actuating elements 17 can, however, also be designed in any other shapes and combinations, it is only important that the coupling element lower parts 6 are adjusted as simply and precisely as possible. After adjustment of a coupling element lower part 6, that is if the coupling element lower part 6 has been brought into agreement with the corresponding coupling element upper part 5, the coupling element lower part 6 can again be fixed on the device lower part 3, for example with fastening elements 10 such as e.g. Screws. The adjustment method according to the invention of the coupling device 1 is completed with these simple steps, as a result of which a repeatable and reliable coupling process is ensured.
Advantageously, the coupling device 1 is always adjusted by means of the method according to the invention when a new object 20, e.g. a new clamping frame 22 in the case of a joining station 18 is used. Normally, not only one object 20 or clamping frame 22 is moved with a lifting device 19 or a gantry crane 21, but a multiplicity of different objects 20 or clamping frame 22. It may therefore be necessary for an upper device part 2 to interact with a large number of lower device parts 3 can, which are fixedly arranged on the various objects 20 or clamping frame 22. In order to be able to guarantee a reproducible, safe lifting process, it is therefore important to adjust all lower device parts 3 to the upper device part 2 at least once by means of the adjustment method, so that all lower coupling element parts 6 of a lower device part 3 can be securely and repeatably coupled to the upper coupling element parts 5 of the upper device part 2 , Through the adjustment process
-1314 / 25
TM-3902 AT small differences in the dimensions of the different device parts 3 can be compensated, e.g. arise due to component and manufacturing tolerances. It may also be necessary to carry out the adjustment process if e.g. Components of the coupling device 1 have to be replaced for maintenance purposes or also after any collisions of the lifting device 19 or the gantry crane 21 or the coupling device 1 with other objects, e.g. during a production process.
According to a particularly preferred variant of the adjustment method according to the invention, a centering sleeve upper part 24 is displaceably arranged for adjustment on a coupling element upper part 5 and a centering sleeve lower part 25 corresponding to the centering sleeve upper part 24 is arranged on the associated adjustable coupling element lower part 6. After centering of the upper device part 2 on the lower device part 3, for example as described by means of centering element 11 and centering mark 12, the lower coupling element part 6 is adjusted until the associated centering sleeve upper part 24, which is displaceably arranged on the coupling element upper part 5, slides into the corresponding centering sleeve lower part 25 solely due to gravity. The adjustment of the lower coupling element 6 can, as already described, e.g. be carried out by hand or by means of adjusting elements 13 arranged on the lower part 3 of the device. As soon as the centering sleeve upper part 24 has slid into the corresponding centering sleeve lower part 25, the coupling element upper part 5 and the coupling element lower part 6 have been centered exactly, whereupon the corresponding coupling element lower part 6 is fixed to the device lower part 3, for example by means of fastening elements 10 such as e.g. Screws. The adaptation of the coupling element lower parts 6 to the coupling element upper parts 5 can thus be substantially simplified and the coupling element lower parts 6 can be brought very precisely into line with their corresponding coupling element upper parts 5. For easier handling during the centering of the upper device part 2 on the lower device part 3, the centering sleeve upper part 24 can be detachably fixed, for example by means of a fixing element 30 on the upper coupling element 5, for example with a clamping screw, the temporary fixing being released again before the lowering element 6 is adjusted, so that the centering sleeve upper part 24 can slide into the centering sleeve lower part 25 with a correspondingly precise position of the lower coupling part 6 relative to the upper coupling part 5. The accuracy of the setting is determined by the interaction between the centering sleeve upper part 24 and the corresponding centering sleeve lower part 25. Centering sleeve upper part 24 and centering sleeve lower part 25 are preferably designed as cylindrical sleeves which can be pushed onto cylindrical sections 31 of coupling element upper part 5 or cylindrical sections 26 of coupling element lower part 6. The centering sleeve lower part inner surface 27 and the cylindrical section 26 of the coupling element 1415/25
TM-3902 AT bottom part 6 preferably has a transition fit and the cylindrical section 31 of the coupling element upper part 5, the centering sleeve upper part outer surface 29 and the centering sleeve upper part inner surface 28 preferably have a clearance fit. Through these tolerance pairings, both a simple pushing of the centering sleeve upper part 24 onto the 5 cylindrical section 31 of the coupling element upper part 5 or of the centering sleeve lower part onto the cylindrical section 26 of the coupling element lower part 6, as well as a sliding of the centering sleeve upper part 24 into the centering sleeve lower part 25, and one can very precise adjustment of the coupling elements 4 can be achieved. Of course, other embodiments, tolerance pairs and materials would also be conceivable, e.g.
A greater play between centering sleeve upper part 24 and centering sleeve lower part 25 could be accepted if no high-precision adjustment is required. Because the material is irrelevant to the invention
