COMMISSIONING SYSTEM AND METHOD FOR LOADING LOADING CARRIES

The invention relates to a method for loading of load carriers with loading units and a picking system with a loading device, as described in the preamble of claims 1 and 6.

EP 1 995 192 A2 discloses a picking system with a loading device for loading of load carriers with loading units for a loading pile, a delivery system with several loading stations for loading units, a loading zone with multiple slots for carriers, wherein the loading device and a charging device to this subsequent sorting device, which sorting device is arranged between the supply system and the loading zone and comprises a decoupled from the loading device movable receiving device.

A method for the automatic loading of load carriers with loading units by means of a loading device is known from WO 2006/065147 A1, in which the loading units provided in a staging system on several supply stations and taken from the loading device and on several charge carriers for a spatial loading configuration for load a stack of charges. The loading device is formed by an articulated-arm robot, which always picks up an isolated loading unit from one of the staging areas and delivers it to one of the load carriers. The loading units are sorted before their takeover by the articulated arm robot in a final load order. A sorting of the loading units by means of Gelenkarmroboters is not required. In this known method, only a limited picking performance is possible.

From EP 1 462 394 B1 and WO 2009/094681 A1, a picking system is known, which has a plurality of loading devices for the automatic loading of load carriers with loading units for a spatial loading configuration for a loading stack, which are connected to an automated loading unit distribution system. Each loading device has only one parking space for the carrier. The loading units are sorted on the conveying path along the distribution system into a loading order defined by the loading configuration and conveyed one after the other in the loading order to a loading place of the loading devices.

According to EP 1 462 394 B1, the provisioning station comprises a stationary pallet from which, by means of a loading device, the separated loading unit is pushed onto an x-position on and relative to the stationary pallet, in which the loading unit is gripped by a transfer device and is conveyed by this in a z-position on the charge carrier. As soon as a charge carrier with a charging stack has been completely loaded by a loading device, a charge carrier changing device exchanges the filled charge carrier with an empty charge carrier. Since the loading device can not perform a loading process during the change process of the load carrier, only a limited picking performance can be achieved. The picking system can only increase the throughput of load carriers to be picked by providing many individual loading devices. High investment costs are inevitably the result.

If the sorting takes place on the conveyor between a storage for the loading units and the loading device, as is the case according to the cited prior art, in case of failure entire logistics sections of the order picking system must be shut down. This threatens the danger that picking orders can not be processed on time.

Furthermore, a picking system for loading units is known from DE 10 2005 061 309 A1, which conveying apparatuses, a provisioning system with a plurality of provisioning units, burst a sorting apparatus with a sorting device Having a plurality of buffer channels, loading and unloading vehicles The delivery system is connected to a first conveyor. The feed conveyor vehicle is movable along the input-side ends of the buffer channels and the pickup vehicles along the output-side ends of the buffer channels. The load units are provided at the staging locations and taken therefrom by the loader vehicle and selectively dispensed onto the buffer channels and dammed in the buffer channels. The unloading vehicle can selectively remove the accumulated loading units from the buffer channels and deliver them to a second conveyor. The buffering of the loading units in the buffer channels limits the picking performance.

The object of the invention is to provide a method for loading of load carriers with loading units and a picking system, in which compared to the known systems an even higher picking performance is achieved.

The object of the invention is achieved by the measures and features in claims 1 and 6. It is advantageous that the sorting compared to the picking method known from the prior art does not have to take place exclusively before the transfer of the loading units to the loading device, but can also be taken over by the loading device which is present anyway.

The loading device can perform a sorting order picking and in a loading order. If, on the other hand, the loading device performs a sorting exclusively in a loading order, the loading units are presorted on the upstream conveying path to the loading device, for example after order picking or loading unit properties, and then sorted by the loading device into a loading order. Thus, the sorting function on the upstream conveyor to the loading device either completely eliminated or significantly simplified.

By relocating the sorting in a well-accessible and manageable by the maintenance personnel logistics section of the order picking system, malfunctions can be localized and resolved faster.

In addition, the arrangement of several parking spaces for several carriers also proves advantageous, since the loading device during the change process of the charge carriers, therefore the replacement of a loaded charge carrier against an empty carrier, a carrier can be loaded on one of the other slots. The loading device can continuously process picking orders without interruption. On the other hand, the loading device can simultaneously carry out the sorting, since it is continuously supplied with loading units in a plurality of staging areas.

It is also particularly advantageous that the loading units are initially put together on the receiving device to a stack row and then conveyed away to the loading device. The stack row may contain load units for only one picking order or multiple picking orders. Thus, within a stack row, one or more loading unit (s) for a first picking order and one or more loading unit (s) for a second picking order, or all loading units of only a single picking order may be included.

Thus, a plurality of loading units are simultaneously manipulated and delivered in particular in a stacking row in the z-direction (stacking depth) in a single loading cycle successively to the loading positions.

A particularly simple and dynamic sorting of the loading units in the loading order is achieved by the measure according to claim 2.

According to the measure according to claim 3, the sorting of the loading units takes place exclusively by the loading device, so that the functionality of the distribution system can be considerably simplified. This makes the order picking system less susceptible to faults 2/31

&& id < AT13 828U1 2014-09-15 < > i < > AT13 828U1   2014-09-15   and a reliable supply of loading units at the staging areas can be achieved.

Another advantage is the measure according to claim 4, since the loading units are conveyed in a presorted order to the staging areas and end sorted by the loading device in a loading order. The presorting can be done with very simple sorting functions either by the distribution system or by a conveyor vehicle in the storage. The loading units can be pre-sorted according to one of the loading unit properties, such as dimensions, dimensional stability and the like, or order picking. As a result, the sorting device of the loading device can, if necessary, be operated below its maximum possible drive power.

Is carried out, as described in claim 5, an evaluation of the delivery order of the loading units, in which they are conveyed to the staging areas, the carriage of the loading units is monitored and carried out a plausibility check. For example, the delivery order can be determined by an electronic monitoring device, for example a sensor system, CCD camera and the like, which has the distribution system. The monitoring device can acquire data from a data carrier arranged on the charging unit. The data carrier comprises a unique, distinctive identification code. The data carrier is preferably formed by a barcode, transponder, magnetic stripe or an RFID label (Radio Frequency Identification Device). On the other hand, the conveying order can be determined by a computer controlling the conveyance of the loading units in the picking system, in particular a material flow computer.

Advantageous embodiments of the invention are also described in claims 7 to 12. The movements of the loading device and the sorting device can be decoupled. In other words, while the sorting device still receives loading units from the staging areas and sorts them into the required loading order, the transfer device of the loading device can reload loading units onto one or more load carriers. As a result, a high throughput of the loading units to be picked is achieved at the loading device. Further decoupling of the conveying movements of the loading units is achieved when the movements of the loading device and the transfer device are decoupled. On the other hand, the loading device and the transfer device can form a structural unit and be adjusted together in the x-direction and / or y-direction. It is also possible for the loading device and the transfer device to be adjustable independently of one another and, if appropriate, to be synchronously adjusted in the x-direction and / or y-direction during a loading process. If the sorting device (first conveying section), feeding device (second conveying section) and transfer device (third conveying section) are each equipped with an automated conveying device, precise positioning of the loading units on each conveying section along the conveying path between the providing system and the load carrier is possible. By controlling the conveying speeds at the conveying devices, a trouble-free transfer of the loading units between successive conveying sections can take place.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

The traction mechanism drive comprises an endlessly circulating traction mechanism 23 which is guided around a deflecting wheel and a drive wheel coupled to a servomotor 24. The direction of rotation of the servomotor 24 is reversible, so that the positioning carriage 20 and thus the conveying device 18b in the x-direction is either moved towards the opposite conveying device 18a or moved away from it. By adjusting the distance between the conveying devices 18a, 18b, an adaptation to different dimensions of the loading units 2 takes place.

The transfer device 3, according to the embodiment shown parallel conveyor tracks 25a, 25b arranged on each of a guide carriage 26a, 26b and are adjustable via a first adjusting device 27 along a guide arrangement in a transfer position in the x direction.

The second traction mechanism drive comprises an endlessly circulating traction mechanism 31 which is guided around a deflecting wheel and a drive wheel coupled to a servomotor 32. The traction means 31 is formed, for example, by a toothed belt, a chain or the like and is firmly connected to the conveying track 25b overlapping guide carriage 26b. By rotating the drive wheels in a clockwise or counterclockwise direction, the conveyor tracks 25a, 25b are moved in the x-direction.

The conveyor tracks 25a, 25b are synchronously adjustable via a second adjusting device 33 also in the z-direction (depth direction of a load carrier) between a retracted take-over position shown in FIG. 2a and an extended loading position shown in FIG. 2b. The conveyor tracks 25a, 25b protrude in their takeover position in the z-direction at the front end of the charging device 4. In the transfer position, either a single loading unit 2 or a plurality of loading units 2 of a stacking row can be received by the transfer device 3.

The extension movement of the conveyor tracks 25a, 25b is made possible by the adjusting device 33, which is formed by a linear drive and has a first and second traction mechanism drive according to the embodiment shown. The traction mechanism drives each comprise an endlessly circulating traction means 34a, 34b, which is guided around a deflecting wheel and a drive wheel. The drive wheels are coupled via a not further shown drive shaft to a common displacement motor 35. The traction means 34a, 34b are formed for example by a toothed belt, a chain or the like, to which a coupling slide 36a, 36b is attached. The traction drives are each mounted on a frame 37a, 37b, of which the right frame 37a with the conveyor track 25a overlapping guide carriage 26a and the left frame 37b with the conveyor track 25b overlapping guide carriage 26b is firmly connected. The direction of rotation of the displacement motor 33 is reversible, so that according to the direction of rotation, the conveyor tracks 25a, 25b extend or retract.

As can be seen from the figures, the conveyor tracks 25a, 25b each have a conveying device with a conveying means 38, in particular a conveyor belt, conveyor belt and the like, which are coupled to a common conveying motor 53. On the other hand, the conveying device of the transfer device 3 can also be formed by a single, not shown drivable belt conveyor. Likewise, the transfer device 3 and charging device 4 can be adjusted as a unit together in the x direction.

As further noted in the figures, the transfer device 3 and charging device 4 as well as the optionally provided alignment device 5 are relatively adjustable on a frame via an adjustment device 39 along a guide arrangement (not shown) also in a vertical direction (y-direction) 11c stored. The adjusting device 39 is formed by linear drives and, according to the embodiment shown, has traction mechanism drives connected to the frames 11a, 11b for the transfer device 3 and the charging device 4. Each traction mechanism drive comprises an endlessly circulating traction mechanism 40 which is guided around a deflecting wheel and a drive wheel coupled to a servomotor 41. By rotational movement of the drive wheel in a clockwise or counterclockwise direction, the transfer device 3 and charging device 4 and the optionally provided alignment device 5 is moved vertically and relative to the charge carriers in the y direction up to a y-position determined by a computer.

As shown schematically in the figures, the sorting device 6 has a receiving device 42 for the loading units 2, which is mounted on a frame 11 d adjustable via a first adjusting device 43 in the x-direction.

Direction) relative adjustable mounted on a frame 11 e. The second adjusting device 47 is formed by linear drives and has shown embodiment shown with the frame 11 d for the sorter 6 connected traction mechanisms. Each traction mechanism drive comprises an endlessly circulating traction means 48, which is guided around a guide wheel and a drive wheel coupled to a servomotor 49. By rotating the drive wheel in a clockwise or anticlockwise direction, the receiver 42 is moved vertically and relative to the feeder 4 in the y direction.

The receiving device 42 has a transfer and transfer device 50, in particular a conveyor, such as a belt conveyor, on.

As further noted in the figures, on the frame 11c, a support arm 51, which can be moved by means of a servomotor 51 in the x direction, is mounted with the load monitoring device 7 for detecting the loading state, such as the current height of the loading stack and / or a loading configuration in a stacked position, is equipped, for example, an acoustic or opto-electronic scanning device.

The transfer device 3, charging device 4 and the receiving device 42 described above each form a conveying plane on which several loading units 2 can be conveyed in succession in the conveying direction 17 at a time.

In Fig. 3 is a detail of a picking system according to the invention is shown, which in the conveying direction of the loading units 2, a distribution system 55 for loading units 2, a delivery system 56 for loading units 2, at least one loading device 1 and a loading zone 57 for charge carrier 58th

The loading device 1 is connected via the distribution system 55 with a schematically illustrated storage 59, which as an input warehouse (pallet warehouse) on delivery containers, such as delivery pallet, delivered loading units 2 in storage shelves 60th

Merrek'MscHts jBtesiitiat AT 13 828 U1 2014-09-15 between warehouses For the storage and retrieval of the delivery pallet 60 (not shown) computer-controlled transport vehicles are arranged in rack aisles between the storage racks.

Furthermore, at least one (not shown) separating device can be provided in the storage warehouse 59. After detecting a picking order, a delivery pallet is outsourced from a conveyor vehicle and the delivery pallet is fed to the singling device, by means of which the loading units 2 are removed from the delivery pallet. Thereafter, the loading units 2 are supplied to the distribution system 55.

The automated distribution system 55 comprises, according to the embodiment shown a conveyor circulation path 61 and a plurality of each rack aisle associated Auslagerbahnen 62, via which the at least one delivery pallet taken, isolated loading units 2 of the conveying orbit 61 are supplied. The distribution system 55 is formed by automated conveying techniques, such as belt conveyors and the like.

The automated provisioning system 56 includes a plurality of staging areas 63 on which loading units 2 are provided and which are each constituted, for example, by a stowage provisioning lane such as belt conveyors and the like.

The loading zone 57 comprises in a row next to each other a plurality of parking spaces 64 for the charge carriers 58, which are each provided with a schematically shown in Fig. Load carrier changing device 78, for example, a drivable roller conveyor. Once a charge carrier 58 is completely loaded with a charge stack, the charge carrier change device 78 exchanges the loaded charge carrier 58 with an empty charge carrier.

As can be seen from this illustration, the loading units 2 can be removed from a plurality of supply locations 63 and distributed to a plurality of charge carriers 58 provided at locally different locations 64 via only one loading device 1.

In the following, with reference to FIGS. 4 and 5, the method for the automatic loading of the load carriers 58 with loading units 2 according to a spatial loading configuration by means of the loading device 1 will be described.

As soon as a picking order, for example for compiling and loading a delivery of goods for a retail outlet, has been recorded on a computer, not shown, the loading units 2 required for a picking order are removed from the stocking 59 and fed to the loading device 1. From the loading units 2, the loading units properties (conveying properties) are electronically recorded in a database of the computer, such as the dimensions, geometry, dimensional stability, surface texture and / or a length / width / height ratio, and stored as master data in a database retrievable.

From these data, an optimized, spatial (three-dimensional) loading configuration for the loading stack 65, therefore the loading positions for the loading units 2 in the loading stack 65 determined or set for each loading unit 2, an x, y, z position in the loading stack 65. The loading positions are determined by the computer taking into account various aspects. Thus, the finished charging stack 65 should be as stable and easy to transport as possible, therefore heavy loading units 2 are positioned below in the loading stack 65 and lighter loading units 2 above in the loading stack 65. Likewise, more sensitive loading units 2 are accommodated at the top in the loading stack 65. Also, the loading stack 65 should be packed as close as possible and as high as possible.

Accordingly, the computer determines a loading configuration optimized for stability and / or volume utilization of the loading stack 65 or the optimized loading positions for the loading units 2.

Also, on the basis of these data on the loading units 2 or the loading unit properties, the distance between the conveying devices 18a, 18b of the alignment device 5 7/31

AT 13 828 U1 2014-09-15 and / or conveyor tracks 25a, 25b are set as described in detail in WO 2009/094681 A1.

In addition, based on the data on the loading units 2, an evaluation of the dimensions of the loading units 2 are performed.

From the wide range of several thousand different loading units 2 dimensional classes are determined and assigned by the computer, the loading units 2 the dimension classes The dimensional classes can vary in any number and arbitrary dimensions ranges (length, width, height) define. Each dimension class usually includes several hundreds of load units 2 of different dimensions.

The stacking capacity of the loading device 1 can be advantageously increased when the computer analyzes the dimensions of the loading units 2 required for a picking order, pre-sorting the loading units 2 according to dimensional classes and after the loading configuration ends sorted and then compressed as a stack row (s) on the Loading positions stores. For this purpose, after a picking order has been detected, the dimensions of all or only some of the loading units 2 required for this picking order are compared by a computer logic, in particular a computer program running on the computer, and at least some of the loading units 2 are divided into one or more dimension classes according to their dimensions.

The sorting according to dimensional classes can be carried out by the loading units 2 from the conveyor vehicle (removal conveyor) outsourced in the required order from the automatic storage warehouse 59 and grouped as a stack row from the distribution system 55 to at least one of the staging 63 promoted. On the other hand, the distribution system 55 may also have a sorting function.

According to another embodiment, sorting can be done by picking orders by the transport vehicle (removal conveyor) required for a picking order loading units 2 sequentially outsourced from the automatic storage warehouse 59 and from the distribution system 55 in the Auslagerreihenfolge to at least one of the stalls 63.1 to 63.4 be promoted.

Accordingly, the already existing conveyor vehicle forms a sorting device, with which a "pre-sorting" of the loading units 2 can take place according to a loading unit property, for example dimension classes, and / or picking orders. The "final sorting" of the loading units 2 into a loading order determined by the loading configuration is carried out by the sorting device 6 of the loading device 1, as described below.

According to a first embodiment, according to FIGS. 4a to 4g, loading units 2.1, 2.2, 2.3 are provided on the staging areas 63.1, 63.2, 63.3, which belong to a dimension class but differ in another property, for example dimensional stability, and should be sorted into a load order determined by the load configuration.

The loading unit 2.2 is to be placed on the load carrier 58.2 at a middle loading position 70 between the loading units 2.1, 2.3. The sorting of the loading units 2.1, 2.2, 2.3 in the required loading order is carried out by the order of removal of the staging places 63.1, 63.2, 63.3. For this purpose, the receiving device 42 is controlled by a computer, not shown, in the x-direction between the takeover positions in front of the stations 63.1, 63.2, 63.3. The computer evaluates the order of the loading units 2.1, 2.2, 2.3, as they are conveyed to the staging areas 63.1, 63.2, 63.3, and is determined by the computer from the conveyor sequence, in which order the receiving device 42 from the stalls 63.1, 63.2, 63.3 the loading units 2.1.2.2, 2.3 should take over.

According to the determined acquisition sequence, the receiving device 42 is initially moved in the first transfer position (Fig. 4b) in the x direction, in which the first 8/31

AT13 828U1 2014-09-15

Loading unit 2.1 is promoted to the receiving device 42. Thereafter, the receiving device 42 is moved in the second transfer position (Fig. 4c) in the x direction, in which the second loading unit 2.2 is conveyed to the receiving device 42. Finally, the receiving device 42 is moved in the third transfer position (FIG. 4d) in the x direction, in which the third loading unit 2.3 is conveyed onto the receiving device 42. During the transfer of a loading unit 2.2, 2.3 from the provisioning station 63.1, 63.2, 63.3 onto the receiving device 42, a loading unit 2.1, 2.2 already located on the receiving device 42 is conveyed by means of the transfer and transfer device 50 in the direction of the charging device 4 (conveying direction 17) ,

Thus, the loading units 2.1, 2.2, 2.3 are sorted on the receiving device 42 in the load configuration, therefore dimensions and dimensional stability of the loading units 2.1, 2.2, 2.3 determined loading order. According to the embodiment shown, the loading units 2.1, 2.2, 2.3 belong to a picking order and are loaded as stack row 71 onto one of the load carriers 58.2.

The receiving device 42 is after the acquisition of the loading units 2.1, 2.2, 2.3 controlled by the computer in the x-direction and / or y-direction in a transfer position relative to the charging device 4 method, in which the loading units 2.1, 2.2, 2.3 of the Receiving device 42 are fed to the feeder 4 (Fig. 4e-f).

In this case, the transfer position of the receiving device 42 can be determined either by the loading positions 70 in the x-direction and y-direction of the currently conveyed loading units 2.1, 2.2, 2.3 or by an actual position of the feeder 4 in the x-direction and y-direction become.

Thereafter, the loading units 2.1, 2.2, 2.3 are conveyed from the loading device 4 to the transfer device 3 (FIG. 4g). The loading units 2.1, 2.2, 2.3 can be aligned in advance by the alignment device (FIG. 1) in a direction parallel to the conveying direction 17.

Since the movements of the feeder 4 and sorting device 6 are performed decoupled, while the loading units 2.1, 2.2, 2.3 are conveyed from the feeder 4 and their transfer device 3 to the loading positions, at the same time the next loading units 2 are sorted ( 4g), which are to be loaded onto the same charge carrier 58.2 in the overlying stack layer 73 or at least one of the other charge carriers 58.1, 58.3, 58.4.

Before the transfer of the loading units 2.1, 2.2, 2.3 of the stack row 70 on the transfer device 3, the conveyor tracks 25a, 25b are still moved to the transfer position, in which depending on the loading units property of the distance 72 (Fig. 4f) between the Conveyor tracks 25a, 25b is set and the loading units 2.1,2.2, 2.3 are handed over centrally relative to the conveyor tracks 25a, 25b. The distance 72 is set to the smallest width of the load units 2.1, 2.2, 2.3 of a stack row 71. Thereafter, the stack row 71 is conveyed from the feeder 4 to the transfer device 3. If the stack row 71 is located on the transfer device 3, it is moved in the x, y, z direction until the stack row 71 is positioned at the intended x, y, z position in the loading stack 65.

If the loading units 2.1, 2.2, 2.3 have also been sorted into a loading sequence determined by the loading configuration and conveyed to the loading device 4, the loading of at least one load carrier 58.2 takes place.

The loading process of the load carrier 58.2 will be described with reference to FIG. 2, wherein, according to the embodiment shown in at least one of several stack layers 73 in a single loading cycle, for example, three loading units 2.1, 2.2, 2.3, therefore a stack row 71 are discharged to the loading positions 70 ,

After the loading units 2.1, 2.2, 2.3 of the stack row 71 have been taken over by the transfer device 3, the conveyor tracks 25a, 25b are moved from their transfer position shown in FIG. 2a relative to the loading device 4 into the first load 9 shown in FIG / 31 asterreidBsd! "Pitwiarot in which the first loading unit 2.1 relative to the extension direction 74 is located above its intended x, y, z position in the loading stack 65. The loading units 2.1, 2.2, 2.3 rest on the conveying means 38. During the extension movement of the conveyor tracks 25a, 25b, the loading units 2.1, 2.2, 2.3 can be positioned on the transfer device 3 by driving the conveying means 38, in particular transported to the front end thereof.

Thereafter, the conveyor tracks 25a, 25b are withdrawn together with the conveying means 38 in the return direction 75, wherein at the same time the conveyor 38 on the support side on the conveyor motor 53 against the return direction 75 in the conveying direction 17 of the loading units 2.1, 2.2, 2.3 is driven. The conveying speed of the conveying means 38 corresponds in magnitude to the return speed of the conveyor tracks 25a, 25b, so that the conveying means 38, in particular the conveyor belts are adjusted down to the bottom of the loading units 2.1, 2.2, 2.3 without relative displacement to the loading units 2.1,2.2, 2.3. The first loading unit 2.1 is deprived of its support on the conveyor 38, so that it tilts with their rear end in the direction 75 on the lower level loading level 76 of the carrier 58.2 or a stacking layer and is turned off at the first loading position 70, as in Figs. 2b and 2c.

After the first loading unit 2.1 has been stored, the conveyor tracks 25a, 25b are moved in the return direction 75 into a second loading position and at the same time the conveying means 38 are driven on the support side 39 against the return direction 75 in the conveying direction 17 of the loading units 2.2, 2.3, so that now also the second loading unit 2.2 their support on the conveyor 38 is withdrawn and the second loading unit 2.2 tilts with their back in the rear direction 75 rear end on the lower level 80 of the load carrier 58.2 or a stacking layer and is turned off at the second loading position 70, such as 2d and 2e shown in the second loading position is the second loading unit 2.2 relative to the extension direction 74 above its intended x, y, z position in the loading stack 65th

In the same way, the third loading unit 2.3 is turned off at the third loading position 70, as not shown further.

After the third loading unit 2.3 has been stored, drive the conveyor tracks 25a, 25b back to their transfer position, where they take over a single loading unit 2 or more loading units 2 a stack row 71 again.

If a stacking layer 73 is completed, the transfer and charging device 3,4 and optionally the alignment device 5 are raised in the y-direction to form a next stack layer 73.

This loading process is advantageous since the transfer device 3 simultaneously manipulates a plurality of loading units 2 in a single loading cycle. This is compared to such known from the prior art loading operations, in which a first loading unit is taken over by the transfer device and conveyed to the first loading position and then a second loading unit is taken over by the transfer device and conveyed to the second loading position, the number of adjustment movements of Transfer device 3 significantly reduced in the z-direction and thus achieved a significant increase in performance of the loading device 1.
