Description
Technical Field
The present invention relates to a loading device for loading an SMT component into an SMT component storage container. The invention further relates to an assembly system for assembling an SMT component to an SMT circuit board, and to a method of providing an SMT component on an assembly system for assembling an SMT component to an SMT circuit board.
Background
In surface mount technology (which is also referred to as "surface mount technology" or simply SMT), surface mounted components (which are also referred to as SMT components, surface mount devices or simply SMDs) are mounted directly on an SMT circuit board and soldered together therewith. A conventional mounting system for mounting an SMT circuit board has: an assembling apparatus or an automatic assembling machine for assembling SMT components to an SMT circuit board, an SMT component storage container for storing the SMT components, and a transfer system for transferring the SMT components to and from the SMT component storage container to the assembling apparatus. By means of the SMT component storage container, SMT components can be temporarily stored and can be taken out of the SMT component storage container when needed, for example when a specific SMT component is required on an assembly device to assemble the SMT circuit board. The transfer system typically has a plurality of transfer cassettes for receiving and transferring SMT components. The loading and unloading of the SMT component storage containers and the loading of the assembly device are typically performed manually using transfer cassettes.
With the known mounting systems for mounting SMT components to SMT circuit boards, and with the method of providing SMT components on a mounting device for mounting SMT circuit boards with SMT components, the disadvantage is that the manual loading and unloading process is very time consuming and therefore very costly. Furthermore, manual activity always increases the risk of errors, for example, the wrong SMT component is removed from the SMT component storage container or may damage the SMT component. Due to the geometry of the SMT components and the construction of the transfer system and the SMT component storage container, a fully automated loading and unloading process cannot be achieved cost-effectively.
Disclosure of Invention
It is therefore an object of the present invention to eliminate or at least partly eliminate the above mentioned drawbacks in a feeding device for loading an SMT component storage container with components, in an assembly system for assembling SMT components to an SMT circuit board, and in a method of providing SMT components on an assembly system for assembling SMT components to an SMT circuit board. The object of the invention is, inter alia, to provide a loading device, an assembly system and a method which improve the handling of SMT components in a simple and cost-effective manner.
The above object is achieved by a loading device for storing SMT components in a container and loading the components into an SMT component, having the features of independent claim 1, and by an assembly system for assembling SMT components to an SMT circuit board, having the features of independent claim 8, and by a method for providing SMT components on an assembly system for assembling SMT components to an SMT circuit board, having the features of independent claim 14. Further features and details of the invention emerge from the dependent claims, the description and the drawings. The features and details described in connection with the inventive charging device and, of course, also in connection with the inventive assembly system and the inventive method or vice versa apply here, so that for the purposes of disclosure reference is always made to individual inventive aspects one after the other.
According to a first aspect of the invention, this object is achieved by a feeding device for loading SMT component storage containers with components. The feeding device has a feeding device for supplying a transfer cassette containing SMT components and an exchanging device for taking out the SMT components from the transfer cassette and loading the SMT component storage containers with the SMT components taken out of the transfer cassette. According to the invention, the supply device has a rotating device, wherein the rotating device rotates the transfer box around a rotation axis between the transfer position and the exchange position. A rotation angle is provided between the transfer position and the exchange position. The loading device is preferably also used for loading the transfer cassette with SMT components arranged in an SMT component storage container.
The supply device is arranged to supply the transfer box. It can be provided that the supply device is formed as part of a transport system for transporting the transport cassettes. Alternatively, the feed device has at least one transfer system interface for connection to such a transfer system. By means of the transfer system interface, the feed device is connected to the transfer system such that the transfer box can be transferred from the transfer system to the feed device and from the feed device to the transfer system again. Preferably, the feeder device has a first transfer system interface for receiving a transfer cassette from a transfer system and a second transfer system interface for connecting to a different interface of the transfer system. The subsequent transfer of the transfer box via the supply device is thus improved.
The rotating device is formed as part of the feeding device. By means of the rotating device, the transfer cassette can be rotated about the axis of rotation from the transfer position to the exchange position and from the exchange position back to the transfer position. In the transfer position, the transfer box can be moved from the transfer system to the feeding device and from the feeding device to the transfer system. The exchange position is the optimal position for taking out SMT components from the transfer cassette. The exchange position is preferably set such that the transfer case opening of the transfer case faces the storage case opening of the SMT component storage case to remove the SMT component. In this case, it is preferred that the transfer box opening is arranged in the exchange position toward the storage container opening, so that a linear movement of the SMT components from the interior of the transfer box into the interior of the SMT component storage container is facilitated. Thus, the movement of the SMT component is improved when the SMT component is transferred from the transfer cassette to the SMT component storage container and when the SMT component is transferred from the SMT component storage container to the transfer cassette. The feeding device is preferably arranged to fix the transfer cassette in the exchange position to improve loading and unloading of the transfer cassette.
An SMT component storage container is a storage device for storing SMT components, which is arranged, for example, in the manner of an intermediate store or stock store of a production system in order to facilitate quick use of the SMT components.
The exchanging device is configured to take out the SMT component from the transfer cassette disposed in the exchanging position and load the SMT component into the SMT component storage container. The exchanging device is preferably arranged to take the SMT components out of the SMT component storage container and load them into the transfer cassette placed in the exchanging position. The removal and/or loading action is preferably performed in a linear motion. The removal movement is preferably performed with a linear pull-out movement and/or the loading movement is preferably performed with a linear push-in movement.
The loading device according to the invention has the advantage that the loading and unloading of the transfer cassettes or SMT component storage containers is improved, since the transfer cassettes can be rotated by means of the rotating device of the feeding device into a transfer position which is particularly suitable for transferring the transfer cassettes, and into an exchange position which is particularly suitable for loading and unloading the transfer cassettes. Thus, automatic loading and unloading is improved by means of the exchange device, and manual loading and unloading is no longer required. The operating time can thus be reduced in a simple manner and at low cost, and the reliability of the charging device is improved compared to conventional solutions.
According to the invention, the axis of rotation is preferably arranged horizontally or at least substantially horizontally. The advantage of a horizontal axis of rotation is that the transfer cassette can be turned over by means of the rotating device, so that unintentional detachment of the SMT components in the transfer position can be avoided and the loading and unloading of the SMT components in the transfer position can be improved in a simple manner and at low cost.
The angle of rotation is preferably between 80 ° and 100 °. The angle of rotation is particularly preferably about 90 °. In this way, the transfer position and the exchange position can be clearly distinguished from one another.
In a preferred development of the invention, it can be provided for the feed device that the transfer cassette has a transfer cassette opening for removing SMT components, wherein the transfer cassette opening is arranged facing upwards or at least substantially upwards in the transfer position and is arranged facing sideways or at least substantially sideways in the exchange position. The upwardly disposed transfer box opening means that the surface of the transfer box opening extends horizontally. The transfer box opening being arranged towards the side face means that the surface of the transfer box opening extends vertically. Preferably, the surface of the transfer box opening in the exchange position is parallel or at least substantially parallel to the surface of the storage container opening of the SMT component storage container in order to enable loading and unloading of the SMT component storage container. The advantage of the transfer box opening facing upwards in the transfer position is that accidental dropping of SMT components from the transfer box can be avoided particularly effectively. The advantage of the transfer cassette opening facing sideways in the exchange position is that the loading and unloading of the transfer cassette can be improved, in particular when the transfer cassette opening faces the transfer cassette opening of the SMT component storage container, since the SMT components here only require a very short path.
It can be provided that the supply device has a rail for guiding the transfer cassette, wherein the transfer cassette can be moved along the rail relative to the supply device. The track is preferably part of the transfer system of the mounting system or coupled to an interface of the transfer system. The rails are arranged in the transfer position in such a way that the transfer cassette is better transferred to the remaining transfer system, in particular via a flush structure. In the exchange position, the rail is rotated about the axis of rotation in such a way that the rail is decoupled from the rest of the transfer system. The advantage of the rail is that the precise orientation of the transfer cassette on the loading device or the feeding device is ensured in a simple manner. The rail has the advantage that the exchange of the transfer cassette with the remaining transfer system can be improved.
It is also preferred that the rail and the transfer cassette are designed such that the transfer cassette is held on the rail in a form-fitting manner. In this case, it is preferred that the transfer cassette engages behind the rail. The rail has, for example, a circular or substantially circular or triangular or trapezoidal cross section, which can then be engaged by the contact section of the transfer cassette or from behind when the transfer cassette is arranged on the rail. For rails with a trapezoidal or triangular cross-section, the broad side of the cross-section preferably faces the transfer cassette. The advantage of this is that the transfer cassette is fixed against lifting from the rail and therefore always remains stable on the rail also in the turned-to-exchange position. Thus, an additional anti-lift device is omitted.
The exchange device preferably has a gripping device for gripping the SMT carrier rollers arranged in the transfer cassette and equipped with SMT components and/or the carrier plate arranged in the transfer cassette, wherein the SMT carrier rollers equipped with SMT components are arranged on the carrier plate. The SMT carrier rollers or carrier plates can be gripped by the gripping device, and the SMT components placed on the SMT carrier rollers can therefore be removed (e.g., pulled out) of the transfer cassette and moved (e.g., pushed into) the SMT component storage container by the exchange device. Preferably, the gripping device is provided for gripping the SMT carrier roller and/or carrier plate arranged in the SMT component storage container, so that the SMT carrier roller or carrier plate together with the SMT carrier roller and the SMT component arranged thereon can be pulled out of the SMT component storage container and can be pushed into the transfer box by means of the exchanging device. The gripping device has the advantage that the SMT support rollers or carrier plates can thus be firmly fixed to the exchange device, so that the positioning reliability of the SMT support rollers or carrier plates in the SMT component storage container and the transfer box can be improved in a simple manner and at low cost.
According to a second aspect of the invention, this object is achieved by an assembly system for assembling SMT components to an SMT circuit board. The mounting system has a mounting device for mounting SMT components to an SMT circuit board, an SMT component storage container for storing SMT components, and a transfer system for transferring SMT components to and from the SMT component storage container to the mounting device. The transfer system typically has at least one transfer cassette for receiving SMT components. The assembly system also has a loading device according to the invention.
The assembly device is arranged for assembling SMT components to an SMT circuit board. The mounting device is preferably designed as an automatic mounting machine. The mounting device preferably has: the conveying device is used for conveying the SMT circuit board; an assembly head for accurately positioning and fixing the SMT components on the circuit board; and an SMT component supply device. The SMT component supply device preferably has a magazine for receiving and supplying SMT components, in particular SMT components arranged on an SMT carrier roller.
The transfer system is preferably arranged for fully automatic transfer of the transfer cassette. For this purpose, the transfer system has, for example, a rail on which the transfer cassettes are displaceably arranged. These rails are preferably arranged such that the transfer cassette can be moved on the rails placed on the feeder device. The transfer system preferably has an automatic transfer device configured to receive the transfer cassette and move within the assembly system. These transfer boxes can thus be transferred to different positions of the assembly system by means of the transfer system.
All the advantages described for the loading device according to the first aspect of the invention apply equally to the assembly system according to the invention. The advantage of the inventive mounting system compared to conventional mounting systems is thus that the loading and unloading of transfer cassettes or SMT component storage containers is improved, since the transfer cassette can be rotated by means of the rotating device of the feeding device into a transfer position which is particularly suitable for transferring the transfer cassette, and into an exchange position which is particularly suitable for loading and unloading the transfer cassette. Thus, automatic loading and unloading is improved by means of the exchange device, and manual loading and unloading is no longer required. The operating time can thus be reduced in a simple manner and at low cost, and the reliability of the assembly system is improved in relation to conventional assembly systems.
In the inventive mounting system, it can be provided that the transfer cassette is provided as an epicyclic magazine of the mounting device for supplying SMT components. Such a transfer cassette can be arranged on the assembly device in such a way that the SMT components and/or the SMT carrier rollers arranged in the transfer cassette can be removed automatically by means of the assembly device. If the SMT components in the transfer box are used up, the transfer box can be easily replaced by the transfer box with the SMT components. The advantage of a transfer box arranged as an epicyclic magazine is that SMT components can be supplied better on the assembly plant. Thus, it is possible to replace the laborious loading of the assembly device with separate SMT carrier rollers by a simple loading of the transfer cassette.
Preferably, the transfer cassette has a first stop means with a plurality of first slots, wherein the first slots are provided for receiving a carrier plate, wherein an SMT carrier roller equipped with SMT components is provided on the carrier plate. Within the scope of the invention, it is of course also possible to apply SMT carrier bars instead of SMT carrier rollers. The adjacent first slots are preferably spaced apart from each other at regular intervals, so that a particularly high accommodation capacity of the carrier plate with the SMT carrier rollers is ensured. Furthermore, the first slot and the carrier plate are preferably designed such that the gripping of the pushed-in carrier plate by the gripping device is effectively ensured. These first slots preferably have guide channels for guiding or for supporting the carrier plate. The advantage of the first latching means is that the carrier plate can be automatically arranged in order in the transfer cassette and can be automatically removed from the transfer cassette in a simple and cost-effective manner.
The SMT component storage container preferably has a second latching device with a plurality of second slots, wherein the second slots are provided to at least partially accommodate a carrier plate, in particular a carrier plate removed from the transfer box, wherein at least one SMT carrier roller equipped with SMT components and/or at least one SMT component equipped carrier bar can be arranged on the carrier plate. The adjacent second slots are preferably spaced apart at regular intervals, preferably in such a way that a particularly high receiving capacity of the carrier plate with the SMT carrier rollers or SMT carrier bars is ensured. Furthermore, the second slot and the carrier plate are preferably designed such that the gripping of the pushed-in carrier plate or the SMT carrier roller or the SMT carrier bar arranged thereon by means of the gripping device is effectively ensured. These second slots preferably have guide channels for guiding or for supporting the carrier plate. The advantage of the second locking means is that the carrier plate can be automatically placed in the SMT component storage container in an orderly manner and at low cost, and the SMT carrier rollers, the SMT carrier bars or the carrier plate can be automatically removed from the SMT component storage container.
According to the invention, adjacent first slots are spaced apart from one another, so that lifting of the SMT support rollers or SMT support bars from the carrier plate can be prevented by the adjacent carrier plates in a form-fitting manner. This is particularly advantageous for the transfer cassette, since it can be rotated between the transfer position and the exchange position to avoid accidental dropping of the SMT carrier rollers or SMT carrier bars. In addition, it is advantageous that the accommodation capacity of the transfer cassette for the loaded carrier plate can be improved as a result. It is also preferred according to the invention that adjacent second slots are spaced apart from one another, so that lifting of the SMT carrier rollers or SMT carrier bars from the carrier plate can be prevented by the adjacent carrier plates in a form-fitting manner. It is also advantageous that the capacity of the SMT component storage container for the loaded carrier board can be improved accordingly.
It is particularly preferred that the carrier plate has an upper side and a lower side for the provision of SMT carrier rollers and/or SMT carrier bars, wherein the first edge region of the carrier plate is locally bent towards the upper side of the carrier plate in order to achieve a centered arrangement of the SMT carrier rollers or carrier bars, and wherein the second edge region of the carrier plate is designed as a guide element and is bent towards the lower side of the carrier plate. The carrier plate is therefore preferably formed by a rectangular or at least substantially rectangular metal plate, which has a bent region. The first edge region bent towards the upper side prevents the SMT carrier roller or the SMT carrier bar from sliding off the upper side of the carrier plate. It is therefore preferred that these first edge regions are bent towards the upper side on all four sides. The second edge region is curved toward the underside and thus prevents the carrier plate from sliding laterally transversely to the insertion direction into the transfer box or the SMT component storage container in a form-fitting manner. The angle of bending is preferably about 90 °. Such a carrier plate can be produced in a simple manner and at low cost. In addition, reliable handling of the carrier plate and stable accommodation of the SMT carrier roller can thereby also be ensured.
According to a third aspect of the invention, this object is achieved by a method of providing an SMT component on an assembly device for assembling an SMT circuit board with an SMT component. The method has the following steps:
providing a transfer cassette 5 by means of a feed device 4 in a transfer position T, wherein the transfer cassette 15 has a plurality of first slots 18, wherein a carrier plate 12 is arranged in at least one of the first slots 18, wherein SMT carrier rollers 13 fitted with SMT components 3 are arranged on the carrier plate 12;
-rotating the transfer box 5 from the transfer position T to the exchange position a by means of the rotating means 7 of the feeding means 4;
gripping the SMT carrier rollers 13 and/or carrier plates 12 arranged in the transfer cassette 5 by means of the gripping means 11 of the exchanging means 6;
-removing the SMT carrier roller 13 from the first slot 18 and moving the SMT carrier roller 13 into the second slot 20 of the SMT component storage container 2 by means of the exchanging device 6;
gripping the carrier plate 12 arranged in the SMT component storage container 2 by means of the gripping device 11;
-removing the SMT carrier rollers 13 and/or carrier plates 12 from the second slot 20 of the SMT component storage container 2 and moving the SMT carrier rollers 13 into the first slot 18 of the transfer cassette 5 by means of the exchanging device 6, wherein said transfer cassette 5 is arranged in the exchanging position a;
-rotating the transfer box 5 from the exchange position a to the transfer position T by means of the rotating means 7; and
the transfer box 5 is set on the mounting device 15 by means of the transfer system 16.
In the case of feeding, the transfer cassette is arranged in the transfer position on the feeding device of the loading device of the assembly system (preferably the assembly system according to the invention) by means of the transfer system. The setting is preferably carried out fully automatically. The transfer cassette is rotated from the transfer position to the exchange position by means of the rotating device of the supply device, preferably about a horizontal or at least substantially horizontal axis of rotation. More preferred angles of rotation are between 80 ° and 100 °, in particular 90 °. The rotation is preferably performed fully automatically. By means of the gripping device of the exchange device, the SMT support rollers or plates are gripped in at least one position and are thus temporarily fixed on this gripping device. The gripping is preferably performed fully automatically. In particular, the SMT carrier roller is removed (e.g. withdrawn) from the first slot, either alone or together with the carrier plate, by means of the exchanging device, and moved (e.g. pushed) into the second slot of the SMT component storage container. The reassignment is preferably performed fully automatically. Subsequently, the gripping device preferably releases the SMT carrier roller or carrier plate fully automatically. Preferably, a plurality of carrier plates are collectively or successively redistributed from the transfer cassette into the SMT component storage container in this manner. These method steps are preferably carried out repeatedly by means of a plurality of transfer cassettes in order to fill the SMT components into the SMT component storage containers. It can also be provided that the SMT component storage containers can be loaded and unloaded with SMT carrier rollers or carrier plates with SMT carrier rollers alternately in almost any desired sequence.
In order to remove the SMT component from the SMT component storage container, the gripping device grips an SMT carrier roller or carrier plate arranged in the SMT component storage container. The SMT carrier roller is preferably selected according to the SMT component required by the assembly device. The gripping is preferably performed fully automatically. The SMT support rollers or the support plate with the SMT support rollers are removed (e.g. pulled out) of the second slot by means of the exchange device and moved (in particular pushed in) into the first slot of the transfer cassette placed in the exchange position. The reassignment is preferably performed fully automatically. Subsequently, the gripping device preferably releases the SMT carrier roller or carrier plate fully automatically. Preferably, a plurality of SMT carrier rollers or plates are redistributed in this way from the SMT component storage container to the transfer box. The loaded transfer cassette is then rotated back into the transfer position by means of the rotating device and moved by means of the transfer system to the mounting device, in particular to the transfer device of the mounting device, in order to transport the SMT components arranged on the SMT carrier rollers to the automatic mounting machine of the mounting device for mounting circuit boards.
All the advantages specified for the loading device according to the first aspect of the invention and for the assembly system according to the second aspect of the invention apply equally to the method according to the invention. The method according to the invention, which provides SMT components on an assembly system for assembling SMT components to SMT circuit boards, has the advantage over conventional methods of improving the loading and unloading of transfer cassettes or SMT component storage containers, because the transfer cassette can be rotated by means of the rotating means of the feeding means into a transfer position which is particularly suitable for transferring the transfer cassette, and can be rotated into an exchange position which is particularly suitable for loading and unloading the transfer cassette. Thus, automatic loading and unloading is improved by means of the exchange device, and manual loading and unloading is no longer required. The operating time can thus be reduced in a simple manner and at low cost, and the reliability is improved compared to conventional methods.
It is particularly preferred that the transfer cassette is arranged on the mounting device in such a way that it is arranged on the mounting device in the form of a turnaround magazine for providing SMT carrier rollers. For example, the arrangement is such that the transfer cassette is pushed into a magazine receptacle of the mounting device and is thus coupled to the mounting device. In this state, the assembling device can selectively take out the carrier plate and/or the SMT carrier roller and/or the SMT component from the transfer cassette. The advantage is that the supply of SMT components is simplified on the assembly device, and the SMT components can therefore be used particularly quickly in the assembly process of SMT circuit boards.

Detailed Description
Fig. 1 and 2 show schematically a preferred embodiment of a loading device 1 according to the invention with a transfer box 5, wherein the transfer box 5 is arranged in a transfer position T in fig. 1 and in an exchange position a in fig. 2. The loading device 1 has a supply device 4 for supplying a transfer box 5. The transfer box 5 is coupled to the rail 10 of the feeding device 4 via an interface. These rails 10 have a trapezoidal cross section, the broad side of which faces the transfer cassette 5. The transfer box 5 is thus positively secured against lifting from the rail 10. These rails are arranged on the platform 25 of the feeder device 4 and are fixed to this platform. The feeder device 4 furthermore has a turning device 7, by means of which the platform 25 can be turned around the axis of rotation 8 at a turning angle V relative to the upright 26 of the feeder device 4 between the transfer position shown in fig. 1 and the exchange position a shown in fig. 2. The angle of rotation V is 90 ° in this preferred embodiment. The transfer cassette 5 held on the stage 25 is rotated by the rotation of the stage 25.
The loading device 1 also has an exchange device 6 with a horizontally and vertically movable gripper device 11. By means of the gripping device 11, a carrier plate 12 (see fig. 6) arranged in the transfer cassette 5 can be gripped, and by means of the exchange device 6, can be pulled out of the transfer cassette 5 and can be pushed into the SMT component storage container 2 arranged adjacent to the loading device 1. Likewise, the carrier plate 12 arranged in the transfer cassette 5 can be gripped by the gripping device 11, and can be pulled out of the SMT component storage container 2 by the exchange device 6 and can be pushed into the transfer cassette 5 placed in the exchange position a. The transfer cassette opening 9 of the transfer cassette 5 faces upward in the transfer position T, and the transfer cassette opening 9 of the transfer cassette 5 faces the SMT component storage container 2 in the exchange position a. In this embodiment, the exchanging device is provided between the feeding device 4 and the SMT component storage container 2.
Fig. 3 to 5 schematically show a top view of a preferred embodiment of the mounting system 14 according to the invention, wherein fig. 3 shows a first state, fig. 4 shows a second state, and fig. 5 shows a third state. The mounting system 14 has a loading device 1, an SMT component storage container 2, a mounting device 15 and a tape transfer cassette 5 and a transfer system 16 with an autonomous transfer device 27. The transfer cassette 5 is arranged as an epicyclic magazine on the assembly device 15 or partially in the assembly device 15 for providing SMT components 3 (see fig. 6). These autonomous transfer devices 27 have two rails 10 for accommodating the transfer cassettes 5 and can be moved within the transfer system 16, for example by means of an electric drive or a computer-based controller. Such an autonomous transfer device 27 has a particularly high flexibility. Alternatively or additionally to the transfer device 27, the transfer system 16 may also comprise a track system, not depicted. The loading device 1 has a feeding device 4 with a column 26, a platform 25 and a turning device 7. The platform 25 can be rotated about the axis of rotation 8 relative to the column 26 by means of the rotating device 7. A rail 10 for fixing the transfer cassette 5 is provided on the platform 25. Furthermore, the loading device 1 has an exchange device 6 with a gripper device 11 for exchanging SMT carrier rollers 13 or carrier plates 12 between the transfer cassette 5 and the SMT component storage container 2 of the assembly system 14. For this purpose, the gripping device 11 is arranged at least horizontally or vertically movable. The charging device preferably corresponds to the charging device 1 in fig. 1 and 2.
In the first state shown in fig. 3, the transfer cassette 5 is arranged on the rail 10 of the autonomous transfer device 27, which is not visible in this figure, and is positioned beside the loading device 1. In the first state, the track 10 of the autonomous transfer device 27 is flush with the track 10 of the platform 25 of the feeding device 4, so that the transfer cassette 5 can be moved from the autonomous transfer device 27 onto the track 10 of the platform 25.
In a second state shown in fig. 4, the transfer box 5 can be moved from the track 10 of the autonomous transfer device 27 onto the track 10 of the platform 25 of the feeder device 4. The transfer box opening 9 of the transfer box 5 is directed out of the plane of the drawing and thus upwards. In the second state, the transfer cassette 5 is thus disposed in the transfer position T.
In the third state shown in fig. 5, the transfer cassette 5 is also arranged on the rail 10 of the platform 25. The platform 25 can be rotated by means of the rotating device 7 relative to the column 26 from the transfer position T into the exchange position a.
