[0001]WORKSTATION FOR TRANSFERRING GOODS BETWEEN LOAD CARRIERS The invention relates to a workstation, in particular a picking station, for transferring goods between load carriers that are accommodated by mobile transport loading aids arranged one above the other, according to the preambles of claims 1, 12, as well as to a picking system according to the preamble of claim 14. Furthermore, the invention relates to a method for transferring goods according to claims 18, 25, in particular by means of such a workstation and / or such a picking system. During transfer of goods, they are removed from a (first) load carrier provided at a first delivery position and placed into one or more (further) load carriers provided at one or more further delivery positions. The goods can comprise one or more items. Various devices and methods are known from the prior art in which the transfermanually by a (picking) person or automated, for example by robots. For example, EP 2607271 A1 describes a method for reloading goods and a workstation designed for this purpose with a work area for one person. In the work area, a straight path runs along which the person can move back and forth between two provided load carriers filled with goods, remove goods from them and place them on additional load carriers provided along the path. JP 2018-070369 A2 discloses a workstation with a work platform for a picking person. In this case, load carriers are provided next to one another at an ergonomic height by means of a vertical section of a conveyor device, so that goods can be reloaded from one of the load carriers into another load carrier provided next to it. US 2006 / 177290 A1 describes a workstation with aWork area, wherein load carriers are provided individually opposite one another. The object of the invention is to provide an improved workstation, an improved order-picking system, and an improved method for reloading goods. In particular, the invention is intended to enable multiple reloading orders to be processed particularly efficiently. This object is achieved by a workstation for reloading goods between load carriers according to the features of claim 1. The control computer is configured to create a reloading instruction that specifies a type of goods to be reloaded in at least one reloading order, a quantity of the goods to be reloaded of this type of goods in the at least one reloading order, a load carrier containing the goods to be reloaded, and a load carrier assigned to the at least one reloading order. Furthermore, the workstation comprises a control device configured to control the lifting devices in such a wayto control that those transport loading aids, by which the load carriers specified by the reloading instruction are received, are moved vertically in order to align the load carriers specified by the reloading instruction with the delivery plane. However, the object is also achieved by a work station for transferring goods between load carriers according to the features of claim 12. The work station for transferring goods between load carriers, which are arranged one above the other and are received by mobile transport loading aids, comprises a work area which is delimited by a first and second vertical plane in the width direction, wherein the vertical planes extend in the longitudinal direction, a delivery plane intersecting the vertical planes, in which a plurality of delivery positions for load carriers are arranged adjacent to the vertical planes and at least partially positioned in the work area, a plurality of provision locations for mobile transport loading aids, which are arranged at aare arranged next to one another on the side of the first and / or second vertical plane facing away from the work area, wherein each provisioning station is assigned at least one loading position, and each provisioning station comprises a lifting device for vertically moving the transport loading aid at the respective provisioning station in order to align load carriers on the loading plane so that the load carriers can be moved from the transport loading aids to the at least one loading position assigned to the respective provisioning station, wherein each provisioning station comprises a stationary lifting device for vertically moving the transport loading aid, wherein the stationary lifting device comprises a vertically extending support structure and a lifting platform adjustably mounted thereon via a lifting drive, wherein the transport loading aid can be placed on the lifting platform, and the workstation additionally comprises a control device which is configured toof the lifting devices in such a way that the transport loading aids are individually moved vertically to such an extent that the load carriers, in particular with their respective bases, are aligned with the delivery plane. An advantage achieved by the invention is particularly that goods of the same type, in particular one or more items (articles) of this goods, from different reloading orders, in particular picking orders, can be removed from a first load carrier and placed into one or more further load carriers assigned to the reloading orders. This allows several reloading orders to be completed essentially simultaneously and thus particularly efficiently. The reloading can be carried out by a reloader, for example a (picking) person or a (picking) robot, which can move within the work area of the workstation for this purpose. The work area can be of any shape, with the vertical planes overlapping one another.opposite each other, so that load carriers can be provided on two (opposite) sides of the work area. In order to provide an equal distance between opposing loading positions arranged along the vertical planes and thus enable ergonomic reloading, it is preferably provided that the work area has a base area with two parallel sides, for example a rectangular base area. It is expedient if the vertical planes run parallel to each other and in particular form the parallel sides of the base area. However, the work area can also be adapted to the available space and, for example, be L-shaped, wherein the vertical planes each comprise two sections which adjoin each other at right angles, so that the vertical planes are also L-shaped. In addition, the work area can also be provided with a circular or ovalbase area. For this purpose, the vertical planes can extend in the longitudinal direction and each be curved around a vertical axis. Thus, the work area can be at least partially enclosed by the vertical planes and thus limited in the width direction. As a rule, reloading orders comprise one or more order lines. Each order line contains at least information about a product type and a quantity of a product of that product type. A first reloading order can comprise three order lines, for example, two bananas, three salami pieces, and one apple. The reloading orders can be recorded (electronically), for example, by means of the control computer of the workstation. The reloading orders can be assigned, in particular by means of the control computer, a load carrier, a receiving compartment, or insert of a load carrier, into which the goods of the reloading order are to be delivered. The reloading orders can beFor example, these can be picking orders, negative picking orders, or refill orders. A picking order is usually based on a customer order. A negative picking order is also usually based on a customer order and specifies for a pre-picked load carrier which of the goods contained therein are not required for the customer order and should therefore be removed from it. For example, the pre-picked load carrier can contain three bananas, three salamis, and two apples. Thus, a negative picking order can specify that a banana and an apple should be removed from the load carrier in order to complete the reloading order given above as an example. Optionally, the negative picking order can also specify a (warehouse) load carrier into which the removed goods should be placed. It is also conceivable that a reloading order consists of both aThis includes both goods to be removed from pre-picked load carriers and goods to be delivered to them. This can be done, for example, in two consecutive reloading steps, in particular according to two reloading instructions. A refill order typically specifies goods to be removed from a load carrier or from a pallet in order to refill a (storage) load carrier. The reloading instruction can be based on one or more reloading orders and is created by the control computer. For example, several customer orders can be processed essentially simultaneously by reloading goods of the same type from different customer orders in one step. For this purpose, the reloading instruction specifies the type of goods to be reloaded, a quantity of goods to be reloaded, a first load carrier containing the goods to be reloaded, in particular in a quantity sufficient for the reloading instruction, and at least one further load carrier.which is assigned to the reloading order(s), and optionally for each additional load carrier a number of items of goods to be reloaded, which are to be placed in the respective additional load carrier. The load carriers are preferably designed to be stackable. In addition, the load carriers can have a single receiving compartment or several receiving compartments (arranged one behind the other) for receiving goods. In this case, it can be provided that several inserts are arranged (one behind the other) in the single receiving compartment or that one insert is arranged in each of the receiving compartments. The inserts can, for example, comprise trays, containers and / or bags. Advantageously, at least some of the load carriers are designed as, in particular stackable, boxes, preferably as plastic or wooden boxes. Alternatively or additionally, at least some of the load carriers can also be designed as cardboard boxes. Optionally, the load carriers can also be designed as stackable drawer boxes.The first load carriers of the load carriers can, for example, contain goods and be provided at the workstation so that the goods to be reloaded can be removed from them. The first load carriers are preferably used for storing goods in a warehouse or storage area of a picking system and are referred to, for example, as storage load carriers. It is expedient if the receiving compartment, the receiving compartments, or the inserts of the first load carriers are each filled with goods of the same type. Additional load carriers of the load carriers can be provided at the workstation and filled with goods, preferably with goods of different types, so that the goods to be reloaded can be placed into them. The additional load carriers can be provided empty or already partially filled with goods of different types, in particular pre-picked. The additional load carriersare preferably used for delivering goods to customers and are referred to, for example, as delivery load carriers. In order to transport several load carriers (simultaneously) to the work device, they are picked up by transport loading aids, which can be provided at the staging points. For this purpose, the transport loading aids can comprise, for example, pallets, transport racks, and / or support frames. The load carriers are picked up by the transport loading aids one above the other, for example, stacked or in stacked shelves of the transport loading aid. In addition, the load carriers can also be picked up next to one another by the transport loading aids. For this purpose, the load carriers can be picked up, for example, as stacks of load carriers arranged next to one another or in stacked shelves of the transport loading aid. Furthermore, the load carriers can also be picked up one behind the other by the transport loading aids.For this purpose, the load carriers can be accommodated, for example, as stacks of load carriers arranged one behind the other or on storage spaces arranged one behind the other in shelf compartments of the transport loading aid. A transport rack can comprise a transport frame which forms several shelf compartments arranged one above the other and / or next to one another for receiving load carriers. The shelf compartments are preferably accessible from a first and / or second access side. Such a transport rack is described, for example, in WO 2022 / 082249 A2, which is incorporated in its entirety into this application. Furthermore, a support frame can comprise a transport frame with several uprights and preferably a floor supported by the transport frame. Such a transport loading aid is described, for example, in WO 2021 / 142498 A1, which is incorporated in its entirety into this application. The load carriers can be arranged on the transport frame or onthe floor, in particular stacked. For example, a loading platform of an automated guided vehicle can be placed against the transport frame of the support frame or the transport frame in order to transport the support frame or the transport frame. The load carriers, in particular cartons, can be stacked on a pallet. If necessary, the pallet can be positioned on a support frame for transport by an automated guided vehicle. The (mobile) transport loading aids are preferably designed to be transportable by means of a transport system. For this purpose, the transport system can, for example, comprise a stationary conveyor system and / or a mobile conveyor system. The transport system, in particular the mobile conveyor system, particularly preferably comprises a plurality of automated guided vehicles, which can be controlled, for example, by a higher-level master computer. Such transport vehicles areknown to those skilled in the art under the terms “Automated Guided Vehicles” (AGVs) or “Autonomous Mobile Robots” (AMRs). By means of the transport system, the transport loading aids can be transported to the provisioning locations, made available there, and / or transferred to a lifting device arranged there, in particular a stationary one. The lifting device, which is arranged in particular in a stationary manner, is designed to raise and / or lower transport loading aids. The lifting devices can align precisely those load carriers, in particular with their lower edge, to the delivery level, which are required to fulfill the reloading order. This reliably prevents picking errors and the load carriers can be delivered at an ergonomic working height. For this purpose, the lifting devices can each comprise at least one vertically movable lifting platform on which the transport loading aids can be placed. In this case, a transport loading aidfor example, from the transport system, in particular from a transport vehicle, onto the lifting platform. Alternatively, the transport vehicle can be parked on the lifting platform using the respective transport loading aid. The lifting platforms of the lifting devices are preferably (continuously) adjustable between a lower position and an upper position. In the lower position, a topmost load carrier of the stacked load carriers, picked up by the transport loading aid, is aligned, in particular with its lower edge, with the loading plane. Furthermore, in the upper position, a bottommost load carrier of the stacked load carriers, picked up by the transport loading aid, is aligned, in particular with its lower edge, with the loading plane. In order to provide the load carriers on both sides of the work area at the same (ergonomic) working height, the loading plane is preferably aligned horizontally. In addition,The delivery positions are arranged in the delivery plane, which are positioned at least partially, in particular, in the work area. For this purpose, the delivery positions preferably border on a side of the respective vertical plane facing the work area. Load carriers for removing and / or delivering goods can be provided on the delivery positions. The load carriers can be moved, for example pulled or pushed, manually or automatically, as described below, by the transport loading aids to the delivery position. It is advantageous if the work station comprises a first and a second side wall, wherein a side of the first side wall facing the work area lies in the first vertical plane and a side of the second side wall facing the work area lies in the second vertical plane, so that the work area is delimited by the side walls in the width direction. The side walls form a physical barrier between the work area and theProvisioning stations, thus increasing safety for a worker in the work area. For this purpose, the side walls can be designed, in particular, as a wall or as a safety grid. In order to enable the transfer of load carriers between transport loading aids and the loading positions, it is preferably provided that the side walls each have at least one loading opening, which extends in the longitudinal direction over one or more loading positions, so that each loading position is assigned a loading opening. The loading openings can extend, in particular in the longitudinal direction, over all loading positions of the respective side wall, so that each loading position along the respective side wall is assigned the same loading opening. Preferably, one loading opening is provided for each provisioning station, which extends over the loading positions assigned to the respective provisioning station. It can also be provided that severalLoading openings are arranged next to one another along the side walls, each extending longitudinally over exactly one loading position. Thus, each loading position is assigned a loading opening. In a simpler embodiment without a loading opening, it can be provided that an upper edge of the side walls runs in the loading plane. It is advantageous if the loading openings each have a door, in particular one that can be opened automatically. Thus, unused loading openings can be closed, for example during a load carrier change, a raising and / or lowering of transport loading aids, thereby further increasing work safety. In this case, it is preferably provided that the control device is configured to control the doors so that (only) those loading openings are opened at which the load carriers specified in the reloading instruction are arranged. To remove the goods from the first load carrierand depositing the goods into the additional load carrier(s), the load carriers specified in the reloading instruction can be moved from the respective transport loading aid to a loading position. This can be done manually by a person pulling the corresponding load carriers from the transport loading aid, in particular through the loading opening, to the loading position positioned in front of the load carrier. After removing or depositing the goods, the load carriers can be pushed back into or onto the transport loading aid by the person. Alternatively, this can also be done automatically. For this purpose, it is preferably provided that a loading device for moving a load carrier, in particular for individually moving several load carriers arranged next to one another, from the respective transport loading aid to a loading position, is arranged at each of the provisioning stations. It is advantageous in this case if the control deviceis configured to control the delivery devices in such a way that the load carriers specified by the reloading instruction are moved from the respective transport loading aid to the delivery position. Furthermore, it is expedient if the control device is configured to control the delivery devices in such a way that the load carriers specified by the reloading instruction, in particular after removing and / or delivering goods, are moved from the delivery position into or onto the respective transport loading aid. Advantageously, the delivery device comprises an ejection device configured to push a load carrier or several load carriers arranged next to one another from the transport loading aid, in particular through the delivery opening, to one of the delivery positions. For this purpose, the ejection device can have one or more horizontally movable pushing elements. Furthermore, the delivery device can have a pulling device configured tois designed to pull a load carrier or several load carriers arranged next to one another from the respective loading position into or onto the transport loading aid. For this purpose, the pulling device can have one or more horizontally movable pulling elements. In order to support the load carriers at the loading positions from below, it is preferably provided that one or more work surfaces are arranged along the first vertical plane and / or along the second vertical plane, which lie in the loading plane and on which the loading positions are arranged. The work surface(s) can each be provided, for example, by a horizontal plate arranged on the respective side wall. It is preferably provided that a, in particular raised, walkable work platform is arranged in the work area, wherein preferably a vertical distance between the work platform and the loading plane is variable. This allows an increasedWorking position and thus a particularly ergonomic working height at which the load carriers are served can be achieved. By changing the vertical distance, the workstation can be adjusted to the body height of a worker. For this purpose, for example, the work platform can be mounted so that it can be moved vertically. To automate the reloading of goods, it can be provided that a robot movable along the longitudinal direction for reloading goods between load carriers provided at the serving positions, in particular a picking robot, is arranged in the work area. The robot can be designed, for example, as an articulated-arm robot or gantry robot movable in the work area, in particular along the longitudinal direction, each with a gripping unit for removing goods. It is advantageous if the workstation has at least one input / output unit, preferably connected to the control computer and / or the control device.which is configured to display the number of goods to be reloaded specified by the reloading instruction and / or a number of goods to be delivered to the load carriers assigned to the at least one reloading order and / or to receive an acknowledgment command. It is advantageous if an input / output unit is arranged at each delivery position so that a number of goods to be removed from or delivered to the load carrier provided at the delivery position can be displayed at each delivery position. Optionally, the input / output unit can also display from which receiving compartment or insert of the load carrier the goods are to be removed or into which receiving compartment or insert of the load carrier the goods are to be delivered. Furthermore, each removal of goods from a load carrier and / or each delivery of goods to a load carrier can be immediately acknowledged. The input / output unit preferably has a screen,in particular a touchscreen, by means of which data relating to the reloading instruction can be displayed, for example, a number of goods to be removed or delivered, an image of the goods, a receiving compartment, and the like. To receive the acknowledgement command, the input / output unit can comprise an input element, for example, a button, a foot switch, a touchscreen, a switch, or the like. The acknowledgement command can be used to acknowledge the delivery and / or removal of goods, i.e., to confirm the successful delivery or removal. Upon receipt of the acknowledgement command by the input / output unit, the respective load carrier can be transferred back from the delivery position to the transport loading aid, and the next load carrier can be prepared for the next reloading instruction. Optionally, the input / output unit can comprise a scanning unit for scanning goods when they are removed from aLoad carrier or when depositing into a load carrier. The scanning unit can be designed, for example, as a barcode scanner, RFID scanner, or QR code scanner. It is also advantageous if the workstation comprises one or more transport loading aids and / or multiple load carriers. It is also advantageous if each staging location comprises a stationary lifting device for vertically moving the transport loading aid. Each lifting device can comprise a vertically extending support structure and a lifting platform adjustably mounted thereon via a lifting drive. The transport loading aid can be picked up or placed on the lifting platform, from which the load carrier(s) specified in the reloading instruction are picked up. This can be a first load carrier containing the goods to be reloaded or a further load carrier that corresponds to at least one reloading order.is assigned, in particular which is filled with the goods. However, this can also be a first load carrier containing the goods to be reloaded, and a further load carrier which is assigned to the at least one reloading order, in particular which is filled with the goods. The lifting drive of the lifting devices is connected to the control device, which in turn controls the lifting devices in such a way that those transport loading aids, by which the load carriers specified by the reloading instruction, in particular one or more first load carriers and / or one or more further load carriers, are received, are moved vertically in order to align the load carriers, in particular with their respective bases, with the loading side. On the one hand, one of the (stationarily arranged) lifting devices can be intended for the transport loading aid, by which the load carrier(s) specified by the reloading instructionspecified first load carrier(s) are received, which, for example, contain(s) goods from a first order, for example, bananas. On the other hand, one of the (stationarily arranged) lifting devices can be intended for the transport loading aid to be placed on the lifting platform, from which the first load carrier(s) specified by the reloading instruction are received, which, for example, contain(s) goods from a second order, for example, apples. The lifting devices can be arranged on a side of the first vertical plane facing away from the work area and next to one another. On the one hand, one of the (stationarily arranged) lifting devices can be intended for the transport loading aid to be placed on the lifting platform, from which the further load carrier(s) specified by the reloading instruction are received, which, for example, are filled with goods for a first order.On the other hand, one of the (stationarily arranged) lifting devices can be intended for the transport loading aid to be placed on the lifting platform, from which the further load carrier(s) specified in the reloading instruction are received, which, for example, is / are filled with goods for a second order. The lifting devices can be arranged on a side of the second vertical plane facing away from the work area and next to each other. It should also be noted that the lifting devices which are arranged next to each other on a side of the first vertical plane facing away from the work area, and the lifting devices which are arranged next to each other on a side of the second vertical plane facing away from the work area, can be arranged on both sides of the work area, as shown, for example, in Fig. 1. By utilizing the advantages and effects described above, the object is further achieved byA picking system of the type mentioned above is solved, wherein the workstation is designed according to one of the aspects described above. The workstation essentially provides a picking station of the picking system. The reloading orders preferably comprise picking orders which are particularly assigned to customer orders. The picking system comprises a transport system for transporting the transport loading aids. The transport system can be designed as described above. Particularly preferably, the transport system comprises a plurality of driverless transport vehicles. This allows the transport loading aids to be moved individually within the picking system. Furthermore, the use of transport vehicles enables rapid installation of the picking system without the complex construction of a stationary conveyor system. Thus, the picking system can be used in existing buildings, for examplein abandoned shops. For storing the goods in the warehouse area, it is preferably provided that several load carriers, in particular first load carriers, with goods of different types are accommodated by some of the transport loading aids. Preferably, the load carriers each have at least one receiving compartment, which is filled with goods of a single type. In this case, the load carriers can be designed, as described above, with a single receiving compartment or with several receiving compartments. Advantageously, it is provided that the order picking system further comprises a warehouse management system and a transport system control unit. In this case, the warehouse management system is preferably configured to record several reloading orders for a defined time window and to create a transport order based on the recorded reloading orders, which transport loading aids and the transport loading aids required for the reloading ordersassigned staging locations of the at least one workstation. Furthermore, the transport system control unit is preferably configured to receive the transport order from the warehouse management system and to control the transport system so that transport loading aids are transported from the storage area to the assigned staging location in accordance with the transport order. The object is further achieved by utilizing the advantages and effects described above by a method according to claim 18, which comprises the following steps: i) detecting reloading orders by means of the control computer of the workstation, wherein the reloading orders each comprise a number of items of goods; ii) providing transport loading aids with load carriers containing the goods of the reloading orders, and transport loading aids with load carriers which are each assigned by the control computer to at least one reloading order; iii) creating a reloading instruction by means of theControl computer, which specifies goods of the same type to be reloaded from at least one reloading order, a first load carrier containing the goods to be reloaded, and at least one further load carrier assigned to the at least one reloading order; iv) Aligning the first and the at least one further load carrier at the delivery side by means of the lifting devices; v) Providing load carriers, wherein the first load carrier specified by the reloading instruction and the at least one further load carrier specified by the reloading instruction are moved by the transport loading aid to the respectively assigned delivery position; vi) Reloading of goods according to the reloading instruction, wherein the goods to be reloaded are removed from the first load carrier at the respective delivery position, in particular by a reloader, preferably in the number of pieces specified by the reloading instruction, and, in particular several pieces of the goods one after the other, are loaded into the at least one further load carrieris delivered; vii) creating a further reloading instruction by means of the control computer, which specifies goods to be reloaded of the same type of goods from at least one reloading order, a first load carrier containing the goods to be reloaded, and at least one further load carrier assigned to the at least one reloading order; viii) repeating steps iv) to vi) for the further reloading instruction. As described above, an advantage achieved with the invention can be seen in particular in the fact that goods of the same type of goods and different reloading orders can be removed essentially simultaneously from the first load carrier and delivered into one or several further load carriers one after the other. As a result, reloading orders, for example picking orders, can be completed essentially simultaneously and thus particularly efficiently. The method is advantageously carried out by means of a previously described workstation and / or by means of a previously describedOrder picking system. The load carriers containing the goods provided in step ii) can, for example, be load carriers used to store goods, or pre-picked load carriers from which negative picking is to take place. “Negative picking” here means removing goods not required for an order from a pre-picked load carrier. Furthermore, the load carriers provided in step ii), which are each assigned to at least one reloading order by the control computer, can be load carriers used to deliver goods to customers. Alternatively, they can be load carriers used to store goods. In this case, goods can, for example, be negatively picked from pre-picked load carriers or unloaded from pallets and placed on a load carrier for storage.It is advantageous if, in step iii), one of the additional load carriers into which goods are or are to be delivered last in step vi) is defined as the last load carrier. This allows the exact load carrier at which the reloading instruction ends to be defined, and thereby also a position can be defined at which the reloader will stop after reloading in step vi). This can be used, in particular, for creating the additional reloading instruction. Furthermore, it is advantageous if the reloading instruction created in step iii) includes a direction of travel along which the additional load carriers are arranged, wherein the additional load carrier which is arranged last in the direction of travel is defined as the last load carrier, and in step vi), goods, in particular several items of the goods, are successively delivered into the additional load carriers provided along the direction of travel, wherein last in thegoods are delivered to the last load carrier. Thus, a sequence can be specified in which the goods, in particular pieces of the goods, are to be delivered to the load carriers, thereby optimizing the path traveled by the reloader during reloading. On the one hand, a particularly ergonomic workflow is achieved when reloading by a person. On the other hand, energy consumption can be minimized when reloading by a robot. It is preferably provided that the longitudinal direction extends between two ends of the workstation and the running direction runs from the end closer to the delivery position assigned to the first load carrier to the end farther from the delivery position assigned to the first load carrier. In order to further minimize the path traveled during reloading, it is preferably provided that the further reloading instruction in step vii) is created such that it includes those goods of the same type of goods that are contained in a load carrier.which is present at a staging location opposite the last load carrier of the (previous) reloading instruction, in particular at its loading position. If the loading openings, as described above, each have an automatically opening door, it is expedient that in step v) (only) the doors of those loading openings are opened at which the load carriers specified by the reloading instruction are aligned. Advantageously, it is provided that a loading device for moving a load carrier, in particular for individually moving several load carriers arranged next to one another, from a transport loading aid to a loading position is arranged at each of the staging locations, and the load carriers specified by the reloading instruction are moved from the transport loading aid to a loading position by the respective loading device in step v). Advantageously, it is provided that the transport loading aids are arranged in aStorage area, in particular in a storage area of a previously described order picking system, and in step ii) are transported from the storage area to the workstation by means of a transport system, in particular by means of driverless transport vehicles. This can preferably be carried out according to a previously described transport order. In order to replenish a warehouse, it can be provided that, for example, goods are removed from load carriers arranged on pallets and placed in provided storage load carriers. In this case, it can be advantageous if the at least one reloading order of the reloading instruction (in each case) is a refill order, wherein in step vi) the first load carrier is completely emptied and the at least one further load carrier is filled (purely sorted) with the goods to be reloaded. Furthermore, it can be provided that the at least one reloading order of the reloading instruction isa picking order, in particular based on a customer order, which comprises one or more order lines, wherein each order line comprises at least information about a type of goods and a quantity of the goods of this type of goods. Furthermore, it is preferably provided that in step ii) some pre-picked load carriers are provided as first load carriers and empty load carriers or load carriers filled with goods are provided as further load carriers, and at least one reloading order, in particular several or all reloading orders, is a negative picking order, which specifies a number of goods per type of goods to be removed from the pre-picked load carrier, wherein in step vi) goods are removed from the first load carriers according to the at least one negative picking order. The object is further achieved by utilizing the advantages and effects described above, by a method for reloading goodsbetween load carriers according to claim 25, comprising the steps: i) recording reloading orders by means of a control computer, wherein the reloading orders each comprise a number of goods; ii) providing mobile transport loading aids comprising a mobile first transport loading aid with first load carriers, which contains the goods of the reloading orders, and a mobile second transport loading aid with further load carriers, which is assigned by the control computer to at least one reloading order; iii) creating a reloading instruction by means of the control computer, which specifies the goods to be reloaded of at least one reloading order, a first load carrier containing the goods to be reloaded, and / or a further load carrier assigned to the at least one reloading order; iv) picking up the mobile first transport loading aid with the first load carriers on a first lifting device of the lifting devices, and picking up the mobile second transport loading aidwith the further load carriers on a second lifting device of the lifting devices, v) aligning the first load carrier by vertically moving the mobile first transport loading aid by means of the lifting platform of the first lifting device, and aligning the further load carrier by vertically moving the mobile second transport loading aid by means of the lifting platform of the second lifting device, respectively at the delivery level (therefore aligning the first load carrier and aligning the further load carrier respectively at the delivery level); vi) providing the first load carrier by moving the first load carrier aligned at the delivery level to the assigned (first) delivery position, and providing the further load carrier by moving the further load carrier aligned at the delivery level to the assigned (second) delivery position; vi) reloading goods according to a reloading instruction, wherein the goods to be reloaded from the goods at the (first) delivery positionprovided first load carrier and, in particular, successively, delivered to the further load carrier provided at the (second) delivery position.

The workstation 1 comprises a work area AB, in which a reloader U, for example a picking person or a picking robot for reloading goods, can move back and forth. The work area AB is delimited in a width direction by two opposing vertical planes VE. In addition, the workstation 1 comprises an imaginary (horizontal)Delivery plane AE, which intersects the two vertical planes VE at a working height. In the delivery plane AE, several delivery positions AP are arranged, shown in Fig. 2, which are at least partially positioned in the work area AB and at which load carriers 3 can be provided. Furthermore, several adjacent provisioning stations BP are provided on the sides of the vertical planes VE facing away from the work area AB. Transport loading aids 2 can be provided at the provisioning stations BP, as shown in Fig. 1. The transport loading aids 2 each accommodate a plurality of load carriers 3 arranged one above the other. The provisioning stations BP each comprise a lifting device 4 for raising and / or lowering transport loading aids 2. The lifting devices 4 are arranged stationary and each comprise a vertically extending support structure 4.1 and a support structure 4.1 adjustable thereon via a lifting drive.mounted lifting platform 4.2. The lifting devices 4 preferably each comprise lifting elements that can be moved vertically on a support structure. In addition, the work station 1 comprises a control system 5, which on the one hand has a control device for controlling the lifting devices 4 in order to align load carriers 3 at the loading plane AE. On the other hand, the control system 5 has a control computer for recording reloading orders and creating reloading instructions. To delimit the work area AB, the work station 1 can comprise two opposing side walls 6, which are each aligned with one of the vertical planes VE. The side walls 6 can further have one or more loading openings 7, which are aligned with the loading positions AP, so that load carriers 3 can be moved through the respective loading opening 7 from the transport loading aid 2 to the loading position AP. Furthermore, the work device can have several, in particularcomprise horizontally aligned storage platforms, which provide the work surface(s) 8. The storage platforms can be positioned such that the work surfaces 8 are in the loading plane AE and the loading positions AP are on the work surface(s) 8. The platforms are preferably mounted on the side walls 6 on a side facing the work area. Optionally, the platforms can also be inclined to allow better accessibility to the interior of the load carriers 3. In the work area AB, a work platform 9 can be arranged, which is preferably spaced from a floor such that the loading plane AE is aligned at an ergonomic height. The work station 1 can, for example, comprise a staircase or ladder, via which the work platform 9 can be reached. To move the load carriers 3 from the transport loading aid 2 to the loading positions AP, at the provisioning stations BPA loading device 10 may be provided. The loading device 10 preferably has an ejection device with several pushing elements 11 and / or a pulling device with several pulling elements, by means of which load carriers 3 arranged next to one another can be pushed to the loading positions AP and / or pulled from the loading positions AP back onto the transport loading aid 2. For reasons of clarity, the loading device 10 is not shown in Fig. 1. Fig. 3 shows a section of the workstation 1 in a cross-sectional view along the line III indicated in Fig. 1. The loading openings 7 are arranged at a vertical distance above the work platform 9. A lower edge of the loading openings 7 lies in the loading plane AE. The loading openings 7 are preferably adapted in height to a height of the load carriers 3 and are at least wide enough for one or more load carriers 3 to be moved through them side by side.can. In order to close the loading openings 7, each of these can have an optional door 12, which is shown in dashed lines in Fig. 3. The door 12 can, for example, be designed as a sliding door that is orthogonal to the loading plane AE and / or vertically movable, as indicated in Fig. 3 by a double arrow. In addition, each staging location BP or, as shown in Fig. 3, each loading position AP can be assigned an input / output unit 13, which is connected to the control system 5 and is configured to display information relating to the reloading instruction and / or to receive an acknowledgment command. As can be seen in Fig. 3, the load carriers 3 are aligned, in particular with their respective bases 3.4, on the loading plane AE. Figs. 4a to 4d show exemplary load carriers 3, each of which comprises at least one receiving compartment 3.1 for receiving goods. The load carriers 3 each also include a base 3.4. TheLoad carrier 3 can, as shown for example in Fig. 4a, have a single receiving compartment 3.1 or, as shown in Fig. 4b, several receiving compartments 3.1, preferably arranged one behind the other, for receiving goods. The receiving compartments 3.1 can, for example, be separated from one another by one or more optional partition walls. Furthermore, it can be provided, in particular as shown in Fig. 4c, that one or more inserts are received in the single receiving compartment 3.1 or one insert each in the several receiving compartments 3.1 of the load carrier 3 for receiving goods, for example a bag 14. The optional partition wall is shown in dashed lines in Fig. 4c. In order to ensure access to the interior of the load carrier 3 even when several load carriers 3 are stacked on top of one another, the load carrier 3 can be designed as a drawer box, as shown for example in Fig. 4d. In this case, the load carrier 3 comprises aOuter part 3.2 and an inner part 3.3 mounted in the outer part 3.2 so as to be extendable, wherein an interior of the load carrier 3 is accessible by a relative extension movement between the inner part 3.3 and the outer part 3.2. According to this embodiment, the outer part 3.2 comprises the base 3.4. In this case, it can be provided that the inner part 3.3 can be moved out of the outer part 3.2 by pulling on a first access side and / or by pushing from a second access side. The inner part 3.3 can be designed as previously described in connection with Fig. 4a to Fig. 4c. A load carrier 3 designed as a drawer box is known, for example, from EP 3423365 B1 and is described therein as a "container". The receiving compartment 3.1, the receiving compartments 3.1 and / or the inserts can each be filled with goods of the same type, for example for storing goods, in particular if the respective load carrier 3 is the first load carrier 3is used. Alternatively, it can be provided that the receiving compartment 3.1, the receiving compartments 3.1 and / or the inserts are each filled with goods of different types. This is particularly advantageous when goods are assembled in such a load carrier 3 according to a reloading order, for example a picking order, and / or the load carrier 3 is used as a further load carrier 3, in particular as a delivery load carrier 3. For this purpose, the reloading instruction can further comprise, for each receiving compartment 3.1 or for each use of the at least one further load carrier 3, a number of items of goods to be delivered into the respective receiving compartment 3.1 and / or the respective insert. Fig. 5a shows a transport loading aid 2 which comprises a transport frame 15 with several uprights 16. As shown in Fig. 5b, several load carriers 3 can be arranged one above the other and / or next to each other on the transport frame 15 and thusTransport loading aid 2 can be accommodated. Optionally, the transport loading aid 2 can comprise a loading floor supported by the transport frame 15 (not shown in Fig. 5b), on which the load carriers 3 can be stacked. Fig. 5c shows a transport loading aid 2 with a transport frame 15, which forms several shelves arranged one above the other and next to one another for receiving load carriers 3. The load carriers 3 can be moved out of or into the respective shelf compartment by pulling on a first access side and / or by pushing from a second access side. Furthermore, the shelf compartments can each have one or more storage spaces arranged one behind the other, on each of which a load carrier 3 can be placed. As shown in Fig. 5c, the transport loading aid 2 can have transport wheels 17 mounted on the transport frame 15. As an alternative to the transport wheels 17, however, uprights 16 can also be provided.as is the case with the transport loading aid 2 shown in Fig. 5a. Fig. 5d shows a transport loading aid 2 designed as a pallet, on which the load carriers 3 are arranged in stacks. The load carriers 3 can be designed as previously described in connection with Fig. 4a to Fig. 4c or can comprise boxes as shown in Fig. 5d. In order to transport the pallet by means of a driverless transport vehicle 18, it can also be received on a transport loading aid 2, which is designed, for example, as described in connection with Fig. 5a and Fig. 5b. Fig. 6 shows a driverless transport vehicle 18 of a transport system, by means of which transport loading aids 2 can be transported. The transport vehicle 18 comprises a loading platform 19 for receiving a transport loading aid 2. Such a transport vehicle 18 is described, for example, in WO 2021 / 142498 A1, in particular on pages 52 and 53.In order to transport the previously described transport loading aids 2, the transport frame 15 can be driven under by the transport vehicle 18 and the loading platform 19 can be placed against the transport frame 15, in particular from below. For this purpose, the loading platform 19 can be designed to be movable vertically, in particular orthogonally to its positioning surface. By means of the described workstation 1, a method 100 for reloading 160 goods between load carriers 3 can be carried out particularly efficiently. Such a method 100 is shown schematically in Fig. 7. Fig. 8a and Fig. 8b show a reloading 160 of goods according to two consecutive reloading instructions. In the method 100, reloading orders are first recorded 110. In this case, several reloading orders, for example picking orders, are recorded by the control computer of the control system 5. For example, four reloading orders can be recorded, wherein a first reloading order contains two pieces of afirst type of goods (e.g. banana) and three pieces of a second type of goods (e.g. salami), a second reloading order comprises one piece of the first type of goods and two pieces of the second type of goods, a third reloading order comprises three pieces of the first type of goods and one piece of the second type of goods, and a fourth reloading order comprises four pieces of the first type of goods. In a next step, transport loading aids 2 are provided 120 at the work station 1. Here, on the one hand, first load carriers 3 comprising transport loading aids 2 are transported to the work station 1. The first load carriers 3 contain the goods included in the reloading orders. Typically, the first load carriers 3 are storage load carriers. On the other hand, further load carriers 3 comprising transport loading aids 2 are transported to the work station 1. The further load carriers 3 can be assigned to the reloading orders, for example, because the further load carriers 3 are empty orare pre-picked and / or can be used for delivery of the goods to customers. The additional load carriers 3 are assigned to the reloading orders before, during, or after the provision 120 of the transport loading aids 2. In addition, in a further step, a reloading instruction is created 130 for the first type of goods covered by the recorded reloading orders. The reloading instruction specifies, on the one hand, the number of goods to be reloaded, i.e., which type of goods and how many of them are to be reloaded. On the other hand, the reloading instruction specifies into which additional load carriers 3 and in what respective number of pieces the goods to be reloaded are to be deposited. In the example given above, the reloading instruction can therefore specify that ten pieces of the first type of goods (bananas) are to be removed from the first load carrier 3 and, according to the reloading orders, two, one, three, and four pieces are to be deposited into the additional load carriers 3 assigned to the reloading orders.are to be transferred. Optionally, the reloading instruction can also specify a running direction LR in which the further load carriers 3 assigned to the reloading orders are arranged in sequence, in particular starting from the first load carrier. In Fig. 8a and Fig. 8b, the running direction is indicated by an arrow. A further load carrier 3 arranged last in the running direction LR can be defined as the last load carrier 3 into which goods are last delivered according to the reloading instruction. The reloader U therefore comes to stand in the area of the last load carrier 3, as indicated by dashed lines in Fig. 8a and Fig. 8b. In a further step, an alignment 140 of those load carriers 3 which are required for the reloading instruction takes place. In this case, the transport loading aids 2, which comprise the first load carrier 3 and the further load carriers 3, are raised or lowered by the respective lifting device 4 in such a way that the load carriers 3 required for the reloading instruction arethe delivery plane AE. The load carriers 3 can then be made available 150 at the delivery positions AP, as shown in Fig. 8a for a first reloading instruction and Fig. 8b for a further reloading instruction. The first and the further load carriers 3 can be moved to the respective delivery position. This can be done manually by the reloader U or automatically by the delivery device 10 described above. In Fig. 8a and Fig. 8b, the first load carrier 3 is each made available at a delivery position AP on the left side of the work area AB and the further load carriers 3 are each made available at a delivery position AP on the right side of the work area AB. The goods can now be reloaded 160 by the reloader U. In this case, the transshipper U removes a number of goods of the first type specified in the transshipment instruction, for example ten bananas, from the first load carrier 3. This can be reported to the transshipper Uat the delivery position AP at which the first load carrier 3 is provided, can be indicated by the input / output unit 13. The successful removal of the goods can be acknowledged by the reloader U using the input / output unit 13. The removed goods can then be delivered to the additional load carriers 3 provided in accordance with the reloading instruction. How many pieces of the goods are to be delivered to the respective additional load carrier 3 can be indicated at the respective delivery position AP by the input / output unit 13. The delivery of the goods to the additional load carriers 3 can also be acknowledged by the reloader U using the input / output unit 13. After the goods to be reloaded have been delivered to the respective additional load carriers 3, the corresponding additional load carriers 3 can be moved back from the delivery position AP to the transport loading aids 2. This can be done manually by the reloader U or automatically by the previouslydescribed delivery device 10. Once all the items of the goods to be reloaded, as specified by the reloading instruction, have been delivered to further load carriers 3, the reloader U comes to a stop in the area of a last load carrier 3, as indicated in Fig. 8a by a reloader U shown in dashed lines. In a further step, a further reloading instruction is created 130. This can take place as described above and after the reloading 160 has been carried out or earlier, for example at the same time as the previously described creation 130 of the first reloading instruction. The further reloading instruction now concerns a further type of goods from the recorded reloading orders. In the example described above, the further reloading instruction can be created for the second type of goods (e.g. salami). The reloading instruction can therefore indicate that six pieces of the second type of goods (salamis) are to be taken from the first load carrier 3 and, according to the reloading orders, three,two, one piece are to be delivered to the additional load carriers 3 assigned to the reloading orders. The fourth reloading order in this example does not include a second type of goods, which is why only three additional load carriers 3 are required, as can be seen in Fig. 8b. As can be seen from a synopsis of Fig. 8a and Fig. 8b, the additional reloading instruction is preferably created such that the corresponding type of goods is available at a staging location BP opposite the last load carrier 3. The alignment 140, staging 150, and reloading 160 according to the additional reloading instruction can be carried out as previously described for the reloading instruction. Fig. 9 shows a picking system 20 in a schematic plan view. The picking system 20 comprises a storage area LB and a picking area KB. The dashed line represents an imaginary dividing line between the storage area LB and the picking area KB. However,These areas do not necessarily have to be adjacent to one another. For example, a transfer area could be provided between the storage area LB and the picking area KB. As can be seen from Fig. 9, a plurality of transport loading aids 2 with load carriers 3 are arranged in the storage area LB. Some of the load carriers 3 contain goods and are used to store the goods in the storage area LB. Likewise, several transport loading aids 2 with empty load carriers 3, with pre-picked load carriers 3 and / or with picked load carriers 3 can be temporarily stored in the storage area LB. In the picking area KB, several previously described workstations 1 are arranged, at which goods can be reloaded between load carriers 3 as described above and thus prepared for delivery to customers. In order to transport the transport loading aids 2 between the storage area and the picking area KB, theThe picking system 20 further comprises a transport system which, as shown in Fig. 9, preferably has a plurality of transport vehicles 18. The transport loading aids 2 and / or the transport vehicles 18 can be designed as previously described. With the picking system 20 shown, the previously described method 100 can thus be carried out, wherein the transport loading aids 2 are transported, for example, during provision 120 from the storage area to the work station 1. Finally, it should be noted that the devices shown may in reality also comprise more or fewer components than shown. In some cases, the devices shown or their components may also be shown not to scale and / or enlarged and / or reduced in size.
