Abstract

The invention relates to a method and an order-picking station for providing loading aids (2.1, 2.2) at an order-picking station, in which method the loading aids (2.1, 2.2) are conveyed to the order-picking station by a conveyance system (20) and are transported there, by a loading aid transport system, to a delivery area (109) for order-picking and are transported back from the delivery area (109) by the loading aid transport system after the order-picking process, the loading aids (2.1, 2.2) each being furnished with a data carrier (52; 53) and being identified by a control device. Before an order-picking process, the loading aids (2.1, 2.2) are conveyed past a first detection device (108) and, from the detection device (108), the control device receives an identification signal if it was possible to read a first data carrier (53), or a read error signal if it was not possible to read a first data carrier (53), and the loading aid transport system is switched by the control device from a first operating mode to a second operating mode if a read error signal has been received.

Description

Picking station and method for providing loading equipment

The invention relates to a method for providing loading equipment, such as containers, carton, tray, etc., at a picking station, in which the loading equipment promoted by a product warehouse via a conveyor system to the picking station and fed to the picking station via a loading equipment transport system a delivery area, for Picking provided in the delivery area and removed after a picking process on the loading equipment transport system again from the delivery area and conveyed away via the conveyor system of the picking station again, the loading equipment each provided with at least one disk and identified by a control device based on the disk become. Furthermore, the invention relates to a picking station for picking items from loading equipment by a picking person.

Recently, people have begun to design the picking process according to the principle of "goods to man." In the goods to man principle, the picking person is assigned a fixed workstation from which he or she moves away as seldom and rarely as possible They are transported to the picking person, which increases the efficiency of a picking system and meets the high ergonomic requirements that are becoming more and more important these days.

The term "article" is understood to mean articles that can be stored in an article store, such as pharmaceuticals, tool parts or the like, which can be ordered by customers in any number and variety, and these ordered articles then become a single order, whereby the articles are then picked into a target container and the picked items are delivered to the customer.

A target container is understood to mean a container into which articles to be picked are placed. A target container can hold a large number of different articles until the picking order assigned to it has been processed, ie until all items belonging to the picking order have been transported from the shelf storage to the workstation and are placed there by the picking person in the corresponding destination container. Such order-picking methods are known from the order-picking systems known from DE 103 07 949 A1, DE 10 2005 045 971 A1, EP 1 572 558 A1, EP 2 098 464 A1, EP 2 050 695 A1, DE 20 2010 005 244 U1 and US 5,246,332 A. realized. Furthermore, WO 2011/103404 A1 discloses a picking station for order picking articles from loading aids, which has an automated first loading equipment transport device (elevator assembly) for transporting loading aids into an operating position and an automated second pick-up assembly transport device. for the removal of loading equipment from the delivery position. The first load carrier transport device has a first receiving unit for a loading aid, which can be moved substantially in the vertical direction, and the second load carrier transport device has a second receiving unit for a loading aid which can be moved substantially in the horizontal direction. In these known order-picking systems, however, there is the problem that the transport routes for the source containers or order containers in the picking system are incomprehensible. The picking person relies on the proper provision of the source containers or order containers. If a source container or order container is not provided for a picking order defined for this, incorrect picking will occur. If incorrect loading aids are provided for a picking order, they must be removed manually or automatically from the picking station. The picking station is blocked during the removal of the wrong loading aid. This is associated with a collapse in the picking performance. The present invention has for its object to provide a method for providing loading equipment at a picking station and a picking station, which allows a high picking performance error-free picking. For this purpose, a corresponding loading aid should also be provided. The object of the invention is achieved by the measures and features of claims 1 and 11. In high-performance order picking stations, per order picker 1000 or more accesses to articles per hour are usually required, so that a false provision of loading equipment avoided and a traceable order picking must be ensured. The invention now provides that each loading aid is conveyed past an order picking process to an electronic detection device and automatically a data carrier is detected. The control device evaluates the data acquisition either by an identification signal, if the data carrier can be read by the detection device, or a misread signal, if the data carrier can not be read by the detection device from. In accordance with an identification signal, the control device can control the loading aid transport system in a first operating mode (normal operation or automatic operation) and corresponding to a fault reading signal in a second operating mode (read-detection operation). By this measure, the transport path of each load carrier is traceable. The loading aids intended for the particular picking order are always provided and unmistakably identified. Thus, a constant picking performance can be achieved. The invention also provides that the second data carrier is detected automatically or manually by an "unidentified" loading aid immediately prior to a picking operation with a second electronic detection device The control device evaluates the data acquisition either by an identification signal if the second data carrier is from the second detection device can be read, or a Fehllesungssig- nal, if the second disk can not be read by the detection device out.

It is favorable if, with the incorrect reading signal, the control device controls the loading aid transport system in such a way that the loading aid, which could not be identified, is moved via the latter into a detection position within a transport path along the loading aid transport system. In the detection position, a second data carrier can be detected by the loading aid, which could not be identified, via a second detection device, and the loading aid can be identified by the control device. The detection position is compared to the Andienungsbereich along the transport path offset so that the detection of the second data carrier manually by the picking person as quickly as possible and can be carried out ergonomically. It can also be provided that the loading aid, which could not be identified on the basis of the first data carrier, is conveyed past the second detection device and the second data carrier is thereby read. The detection device is stationary and arranged such that the loading aid does not have to be moved from the delivery area. The loading aid is located in the detection position in the delivery area and can be started immediately after the detection of the data carrier and identification of the loading aid the picking process.

The control device can, in accordance with an identification signal, control the loading auxiliary transport system in the second operating mode (read-detection mode) such that, for the time being, the loading aid is moved from the detection position into the delivery area after the second data carrier has been correctly detected or the loading aid remains in the detection position. The movement of the loading aid from the detection position to the delivery area can be automated or carried out manually by the picking person. On the other hand, the control device can control the loading equipment transport system in the second operating mode (read-detection mode) in such a way that the still unidentified loading aid is conveyed away from the picking station in accordance with a further incorrect read signal when detecting the second data carrier automated conveyance of an error handling location, where the defective data carriers are removed from the load carrier and new data carriers are placed on the load carrier.

With the error reading signal, an error message is output optically and / or acoustically by the control device at an output unit. The error message may contain an input request for the order picking person, which, for example, directly

Can initiate work steps. Thus, by inputting a control command to an input unit, the order picking person may cause the control device to move the loading aid to the detection position. It is particularly advantageous if the first data carrier and second data carrier are attached to locally different surface sections of the loading aid. The first data carrier is preferably attached to a first side wall of the loading aid and the second data carrier is attached to a second side wall of the loading aid. Is a third data carrier and fourth disk provided so they are preferably attached to a third side wall and fourth side wall of the loading aid, so that the detection devices can detect the respective data carrier on all sides. The data carriers contain the identical data.

It is also advantageous if the loading aid transport system has a first receiving unit, which can be moved substantially in the vertical direction, for a loading aid and a second receiving unit for a loading aid which can be moved substantially in the horizontal direction. The receiving units can either be moved independently of one another via separate positioning drives whose drive motors are connected to the control device. On the other hand, the recording units can be moved synchronously via separate positioning drives, whose synchronized driven drive motors are connected to the control device. Or the receiving units are synchronously moved by means of a common positioning drive whose drive motor is connected to the control device.

The picking station is equipped with the first detection device for detecting a first data carrier. The detection device is integrated in the picking station and protected from external environmental influences.

The picking station is equipped with a second detection device for detecting a second data carrier. The detection device is integrated in the picking station and protected from external environmental influences. On the other hand, the detection device may be designed as a mobile detection device, which can be used for several picking stations and not each picking station must be equipped with its own detection device.

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

Also, the position information selected in the description, such as top, bottom, side, etc. are related to the directly described and illustrated figure and are mutatis mutandis transferred to the new location in a change in position. In the following the invention will be described in connection with containers. The term "container" is not intended to be limiting, but rather is to be understood as an example of a variety of possible loading aids, such as tray, pallet, cardboard, etc., which can be used to store and transport articles or picking ,

The storage system shown in FIG. 1 comprises a shelf storage 1 (article storage), an automated conveyor system for storing source containers 2 in the rack storage 1 or outsourcing of source containers 2 from the rack storage 1, an automated first conveyor system, in particular distribution system 3, a Variety of picking jobs 4, each with a picking 5 for picking items from at least one source container 2 in at least one target container 6 by a picking 7. The number of order-picking 4 may vary depending on the article range and / or throughput.

If a particularly high throughput or order-picking performance is required, the storage system can also have an automated second conveyor system, in particular distribution system 8, and a multiplicity of order-picking workstations 9, each with a picking system 5 for picking articles from at least one source container 2 into at least one destination container 6 by a picking person 7. The picking work stations 9 are preferably identical to the picking 4 trained.

The shelf storage 1 has storage shelves 10 arranged in parallel, in which the source containers 2 are mounted on single or, as shown, double-deep storage spaces 11 in superimposed shelf levels. Between the storage racks 10, a rack aisle is formed, in which at least one computer-controlled rack conveyor vehicle 12 can be moved on rails. According to the embodiment shown, the rack conveyor vehicle 12 is equipped with a vertical mast, a platform 13 which can be raised and lowered on the vertical mast, and with a schematically indicated load receiving device 14, by means of which the source containers 2 can be stored and retrieved. Each shelf vehicle 12 serves two opposite storage racks 10th According to another (not shown) embodiment, it is also possible that the shelf storage 1 in the racking levels respectively attached to the storage racks 10 and along the rack aisle running guide rails and in at least some of the shelf levels on the guide rails movable, autonomous Einbenenregalbediengeräte (shuttle) for transport the source container 2 comprises the parking spaces, wherein the single-level rack operating device with the

Load receiving device 14 equipped by means of which the source container 2 can be stored and swapped.

The rack aisle is provided at its front end with a Einlagerbahn 15 and Auslagerbahn 16, which extend in the extension of the storage shelves 10. On the storage path 15, for example, a roller conveyor, belt conveyor, and the like., Source container 2 are delivered and then transferred to the rack conveyor vehicle 12. The transfer movement of a source container 2 between the storage track 15 and the platform 13 can take place automatically by the load receiving device 14 or by a loading device (not shown), for example a slide, which is separate from the shelf transport vehicle 12.

On the Auslagerbahn 16, for example, a roller conveyor, belt conveyor, and the like., Source container 2 are conveyed away, which are previously discharged from the shelf conveyor vehicle 12 on the Auslagerbahn 16. The transfer movement of a source container 2 between the platform 13 and the outfeed path 16 can take place automatically by the load receiving device 14 or by a separate from the shelf conveyor vehicle 12 formed (not shown) discharge device, such as a slide. The automated conveyor technology for storing source containers 2 in the rack storage 1 or outsourcing source containers 2 from the shelf storage 1 accordingly comprises at least one rack conveyor 12 per shelf aisle, the storage path 15 and the outfeed path 16. The rack storage 1 can comprise one or more rack aisles. The order-picking workstations 4 are connected to the rack storage 1 via the automated first distribution system 3. The first distribution system 3 comprises a conveying circulation path with rectilinear conveying path sections 17, 18 extending perpendicularly to the rack aisles and transporting in opposite directions, and connecting them at the ends Conveyor track sections 19. The conveyor circulation path is formed, for example, by a roller conveyor, belt conveyor, chain conveyor and the like.

The storage and retrieval webs 15, 16 are connected to the first conveyor track section 17 of the distribution system 3. The picking workstations 4 with the respective picking system 5 are connected to the distribution system 3, in particular the second conveying path section 18, via a first conveyor 20 (FIG. 2) for source container 2 and first conveyor 21 (FIG. 2) for target container 6. The first conveyor 20, 21 may be part of the first conveyor system and optionally the second conveyor system.

As schematically indicated in FIG. 1, an automated delivery path 22 can also be connected to the distribution system 3, by means of which empty target containers 6 are provided and conveyed to the distribution system 3. Also, an automated return storage track 23 can be connected to the first distribution system 3, by means of which source container 2, which still contain articles after a picking process, can be conveyed to the first distribution system 3 and from there back to the rack storage 2. Emptied source container 2, from which all articles were removed after at least one order picking process, are conveyed by means of the return storage track 23 to a collecting station 24. Emptied source containers 2 can also be used as destination containers 6, for which purpose they are supplied to the preparation web 22.

It is also possible that a destination container 6 for a picking order at several order-picking 5 must be loaded with different articles and from the first order picking 5, where a "first Teilkommissionierung" carried on the first distribution system 3 and optionally second distribution system 8 promoted and the second Picking system 5 must be discharged, where a "second Teilkommissionierung" takes place. For this purpose, the "partially picked" target container 6 from a third conveyor system, in particular distribution system 36, as will be described in more detail, on the return storage track 23 on the first distribution system 3 and optionally thereafter promoted to the second distribution system 8.

The source containers 2 required for a commissioning order from the shelf storage 1 can be conveyed via an infeed device 25 between the outfeed conveyor 16 and the distribution system 3 be handed over automatically. The infeed device 25 is formed for example by a belt converter, which is integrated in the outfeed track 16 at the end. On the other hand, the Einschleusvorrichtung 25 may also be formed by an actuatable by means of an actuator slide.

The empty target container 6 required for a new picking order can be automatically transferred via an infeed device 26 between the provisioning web 22 and the distribution system 3. The infeed device 26 is formed for example by a belt converter, which is integrated in the supply path 22 end.

Source container 2, which after a picking process at one of the picking 4 jobs; 9 are no longer needed and still contain articles can be transferred automatically via a Einschleusvorrichtung 27 between the return path 23 and the distribution system 3. The infeed device 27 is formed, for example, by a belt converter, which is integrated in the rear storage track 23 at the end.

Still partially filled source containers 2 are automatically transferred via a discharge device 28 between the distribution system 3 and a storage path 15. The ejection device 28 is formed, for example, by a belt converter, which is integrated in the storage area 17 adjacent to the storage rack 1. On the other hand, the discharge device 28 may also be formed by a slide which can be actuated by means of an actuator.

The source containers 2 required for a picking order and conveyed to the first distribution system 3 are automatically transferred to the respective picking station 4 or to the respective picking station 5 via a discharge device 29 between the first distribution system 3 and the first conveyor 20 for source containers 2.

The need for a picking order and promoted on the first distribution system 3 empty target container 6 are automatically transferred to the respective picking 4 or at the respective picking station 5 via a device 30 between the first dispensing system 3 and the first conveyor 21 for target container 6 , As described above, the storage system may further comprise a second distribution system 8, to which the order-picking work stations 9 are connected, and which connects the picking work stations 9 to the rack storage 1. The second distribution system 8 comprises a conveying circulation path with rectilinear conveying path sections 31, 32 extending perpendicularly to the rack aisles and transporting in opposite directions, and the conveying path sections 33 connecting the ends. The conveying circulation path is formed, for example, by a roller conveyor, belt conveyor, chain conveyor and the like.

The straight-line conveyor track sections 17, 31 of the distribution systems 3, 8 form a single conveyor track section. The conveyor track sections 33 of the second distribution system 8 extend in the extension of the conveyor track sections 19 of the first distribution system 3. In this case, the allocation of the source containers 2 and order containers 6 either to the conveyor circulation path of the automatically controllable conveyor switches 34 arranged in the crossing regions of the distribution systems 3, 8 Distribution system 3 or the conveying orbit of the distribution system 8 done.

The order-picking work stations 9 with the respective order picking system 5 are in turn connected to the second conveyor track section 32 via a first conveyor 20 (FIG. 2) for source container 2 and first conveyor 21 (FIG. 2) for destination container 6.

The source containers 2 required for a picking order and conveyed to the second distribution system 8 are automatically transferred to the respective picking station 9 or to the respective picking station 5 via a discharge device 29 between the second distribution system 8 and the first conveyor 20 for source containers 2.

The target containers 6 required for a picking order and conveyed to the second distribution system 8 are automatically transferred to the respective picking station 9 or to the respective picking station 5 via a discharge device 30 between the second distribution system 8 and the first conveyor 21 for target containers 6. For distributing the source and target containers 2, 6 on the respective order-picking 4; 9 or picking station 5 provided Ausschleusvorrichtungen 29, 30 are formed for example by a belt converter, which is integrated in the shelf storage 1 remote conveyor track section 18, 32. On the other hand, the Ausschleusvorrich- device 29, 30 may also be formed by an actuatable by means of an actuator slide, which is opposite to the first conveyor 20, 21.

The first distribution system 3 forms a first (lower) conveying plane 35 (FIG. 2), on which the source and / or target containers 2, 6 can be transported to one or more picking stations 5 in accordance with the arrows. Likewise, the second distribution system 8 forms, if provided, a first (lower) conveying plane 35 (FIG. 2), on which the source and target containers 2, 6 can be transported in the conveying direction according to the arrows to one or more picking stations 5 , The storage system shown in Fig. 1 further comprises an automated third distribution system 36, which is preferably disposed above the first distribution system 3 and a conveying orbit with extending perpendicular to the rack aisles and transporting in opposite directions, straight conveyor sections 37, 38 and this end connecting conveyor track sections 39 includes. The conveying orbit is formed, for example, by a roller conveyor, belt conveyor, chain conveyor and the like.

The third distribution system 36 forms a second (upper) conveying plane 40 (FIG. 2) on which the source and / or target containers 2, 6 can be transported away from one or more picking stations 5 in the conveying direction according to the arrows indicated, preferably to the rack storage 1 are.

The order-picking workstations 4 are connected to the respective order picking system 5 via a second conveyor 41 (FIG. 2) for source container 2 and second conveyor 42 (FIG. 2) for target container 6 to the distribution system 36, in particular the first conveyor section 37. The second conveyor 41, 42 may be part of the third conveyor system.

The after a picking from the picking station 5 abzufordernden (partially or completely empty) source container 2 can via a Einschleusvorrich- tion 43 between the second conveyor 41 and the distribution system 36 are automatically transferred.

The destination containers 6 to be picked up by the picking station 5 after a picking operation can be automatically transferred via an infeed device 44 between the second conveyor system 42 and the distribution system 36.

The insertion device 43, 44 is formed for example by a belt converter, which is integrated in the second conveyor 41, 42 end.

To the third distribution system 36, the automated return storage path 23 is connected, which in turn is connected to the first distribution system 3, so on the one hand partially empty source container 2 from the respective order picking 5 to the first distribution system 3 and from this to the rack storage 1 and on the other hand completely empty source container. 2 can be fed back from the respective picking station 5 to collecting station 24. The return storage track 23 has a gradient track section for bridging the level difference between the first and third distribution systems 3, 36. On the other hand, the return storage track 23 may also be formed by a vertical lift which connects the first (lower) conveying plane 35 and the second (upper) conveying plane 40 or the distribution systems 3, 36 to one another.

The source containers 2 are automatically transferred via a discharge device 45 between the third distribution system 36 and the return storage path 23.

An automated conveyor track 46, in particular a buffer conveyor track, is connected to the third distribution system 36, which conveys destination containers 6 completed to the picking orders. The conveyor track 46 may lead to a consolidation warehouse (not shown) or goods exit (not shown).

The target containers 6 are automatically transferred via a discharge device 47 between the third distribution system 36 and the conveyor track 46.

The discharge device 45, 47 is formed for example by a belt converter, which is integrated in the conveyor track section 39. The order-picking workstations 9 with the respective order-picking system 5 are again in the same way as the order-picking workstations 4 via the second conveyor 41 (FIG. 2) for source container 2 and second conveyor system 42 (FIG third distribution system 36, in particular the second conveyor track section 32 connected.

As schematically indicated in FIG. 1, along the first conveyor system or distribution system 3 (and / or optionally the second conveyor system or distribution system 8) are in the vicinity of each ejection device 29, 30 assigned to each picking station 48, 49 (to be described in greater detail) arranged detection devices 50 are provided. Of course, the detection devices 50 can also be provided at a different location, since it is only decisive that the loading aids 2, 6 before their transfer from the first conveyor system or distribution system 3 (and / or optionally the second conveyor system or distribution system 8) to the picking station 48, 49, in particular to the subsequent to the Kommissioniersta- tion 48, 49 conveyor 20, 21 are identified.

The detection devices 50 are, for example, readers with which data can be read from an identification system; in particular, the loading aids 2, 6 can be uniquely identified. If the loading aids 2, 6 are conveyed on the first conveyor system or distribution system 3 (and / or optionally the second conveyor system or distribution system 8) along a transport path between the article store and the order picking station 48, 49, the loading aid 2, 6 will be at least a detection device 50 passes and thereby automatically detects data of the identification system and a control device 51, in particular a warehouse management computer, transmitted. For this purpose, the detection devices 50 are connected to the control device 51 via a line system, not shown, in particular a bus system.

Each loading aid 2, 6 is equipped with the identification system, which comprises at least one data carrier 52. It proves to be advantageous if the identification system comprises at least a first data carrier 52 and a second data carrier 53. The data carriers 52, 53 are arranged on loading aids 2, 6 at locally different surface sections. As can be seen in FIG. 2, the loading aids 2, 6 form a bottom and side walls projecting therefrom, the first data carrier 52 forming on a first side wall. wall (surface portion) and the second volume 53 on a second side wall (surface portion) are arranged. Of course, both data carriers 52, 53 can also be arranged side by side or one below the other on only one side wall. The detection devices 50 are arranged and arranged relative to the first conveyor system such that the first data carrier 52 can be detected on the loading aid 2, 6 when the loading aid 2, 6 is moved past the detection device 50.

The data carriers 52, 53 are preferably identical and contain the same data. At the very least, however, the data carriers 52, 53 contain data which are identical in both data carriers 52, 53, for example an unmistakable loading equipment identification number. Based on the loading aid identification number, the control device 51 can infer a unique assignment of a loading aid 2, 6 to a picking order or customer order and / or content (article or picking item) in a loading aid 2. The data carrier 52, 53 may also contain content-related data, for example a batch number.

The data carrier 52, 53 can be formed by a bar code label, a transponder, magnetic strip or an RFID tag (Radio Frequency Identification Device) and are stored or stored in this preferably machine-readable data. The RFID is a microchip with an antenna on which data is stored passively, so they do not emit any signals but allow the reader to trigger them with radio waves and then disclose their information. The energy necessary for the transmission of the data is obtained by the radio signal received by them. The data transmission takes place on the basis of electromagnetic alternating fields without contact between the RFID tag and the reader.

The detection device 50 is formed depending on the type of data carrier 52, 53 as a barcode reader, transponder reader, card reader or scanner.

FIG. 2 shows an exemplary embodiment of a picking system 5 which comprises a picking station 48 for target containers 6 and picking stations 49 for source containers 2 arranged on both sides thereof. The Kommissioniersy system 5 includes at least one input unit 54 and at least one output unit 55. The input unit 54 is, for example, a keyboard or Acknowledgment key, with which the end of a picking process can be confirmed. The output unit 55 comprises an optical display, for example a screen, and / or acoustic output, for example a loudspeaker, with which the number of articles to be taken from the source container 2 can be displayed. The input unit 54 and output unit 55 are connected to the control device 51.

The order picking stations 48, 49 each comprise a frame which forms side walls 56 (first frame wall parts), a front wall 57 (second frame wall part) and a top wall 58 (third frame wall part). The side walls 56 (first frame wall parts), front wall 57 (second frame wall part) and top wall 58 (third frame wall part) form a housing (housing) for a container transport system to be described in more detail and, if appropriate, a container delivery device. The side walls 56 are arranged on both sides of the conveyor techniques 20, 21, 41, 42 and run parallel to each other. The front wall 57 connects the side walls 56 on one of the conveyor techniques 20, 21, 41, 42 opposite front of the housing. The conveying techniques 20, 21, 41, 42 arranged in the superimposed conveying planes 35, 40 extend on a rear side of the enclosure between the side walls 56 through an opening 59. The top wall 58 extends above the second conveyor techniques 41, 42 and connects the side walls 56 to a top of the enclosure.

The top wall 58 is provided with a window-like recess 60, through which the order picking person 7 access to a source container 2 and target container 6 is created to remove items from the source container 2 and store items in the target container 6. The recess 60 may be formed with a first longitudinal dimension (width) and a second longitudinal dimension (length) that is larger than a first longitudinal dimension 106 (width) and a second longitudinal dimension 107 (length) of the loading aid 2, 6.

The order-picking station 48, 49 is a self-sufficient module unit, which can be combined with another order-picking station 48, 49 to the order-picking system 5 as desired. For example, only one picking station 49 for source container 2 and one missionierstation 48 are combined for target container 6. On the other hand, the order-picking station 49 for source containers 2 can be arranged between picking stations 48 for destination containers 6. On the other hand, it is also possible that only one or more picking station (s) 49 for source container 2 at the picking 4; 9 is provided, and in addition to the order picking station 49 one or more buffer locations is (are) provided on which (n) a loading aid, such as a pallet, can be provided.

The picking stations 48, 49 are each independently controllable, so that the conveying movements of the source and target containers 2, 6 are decoupled from each other. If a picking station 48 and two picking stations 49 are provided, as shown in FIG. 2, source containers 2 and destination containers 6 can be provided simultaneously for different picking orders. Thus, for example, for a first order picking order, at least one article from the first source container 2 provided in the left picking station 49 can be placed in the destination container 6, while at the right picking station 49 a second order picking order 49 Source container 2 is provided. This achieves a high picking performance. As entered in FIGS. 1 and 2, the picking station 48, 49 is assigned a detection device 108. The detection device 108 is set up and arranged such that the second data carrier 53 can be detected on the loading aid 2, 6 when the loading aid 2, 6 is moved past the detection device 108. According to the embodiment shown, the detection device 108 is arranged in the region of the side wall 56. For better understanding, the detection device 108 has also been entered in dash-dotted lines in FIGS. 4 to 16, with which the detection area is symbolized.

The detection device 108 is arranged along the first conveying device 20, 21. Although in a preferred embodiment, the picking station 48, 49 includes the detection device 108, it is equally possible for the detection device

108 is provided at another point, since it is only decisive that the loading aids 2, 6 are identified in a delivery area 109 (FIG. 5) before the upcoming order picking process. Preferably, the detection device 108 is along a trans- 4) between the first conveyor 20, 21 and second conveyor 41, 42 arranged.

The detection device 108 is, for example, a reading device with which data can be read from a second data carrier 53; in particular, the loading aids 2, 6 can be uniquely identified. If the loading aids 2, 6 are conveyed from the first conveyor system or distribution system 3 (and / or optionally the second conveyor system or distribution system 8) to the order picking station 48, 49 in the delivery area 109, then the loading aid 2, 6 is applied to at least one detection device 108 passes and automatically detects data of the second data carrier 53 and the control device 51, in particular a warehouse management computer, transmitted. For this purpose, the detection device 108 is connected to the control device 51 via a line system, not shown, in particular a bus system. The detection device 108 is formed depending on the type of the data carrier 53 as a bar code reader, transponder reader, card reader or scanner.

As will be described later, when the second data carrier 53 is damaged, a reading operation by the detecting device 108 can not be performed. It is therefore necessary for the loading aid 2, 6 to be uniquely identified by the control device 51 even before a picking operation in order to make the picking operation comprehensible. For this purpose, an additional detection device 110 for detecting the first data carrier 52 is now provided, as shown in the different embodiments according to FIGS. 10, 13 and 15. For this purpose, the detection device 110 is connected to the control device 51 via an unillustrated line system.

Detector 110 may be either a stationary mounted reader (FIG. 15) as described above or a mobile reader (FIGS. 10, 13), such as a handheld scanner. If a stationary detection device 110 is provided for detecting the first data carrier 52, as FIG. 15 shows, then each picking station 48, 49 is assigned a detection device 110. For example, the detection device 110 is arranged in the region of the front wall 57 such that the loading aid 2, 6 on the detection device 110 and thereby automatically data of the first data carrier 52 can be detected, wherein the data of the control device 51 are transmitted.

If a mobile detection device 110 is provided for detecting the first data carrier 52, as shown in FIG. 10 or 13, then one or more picking stations 48, 49 are assigned a detection device 110. This is operated by the picking person 7. Accordingly, the picking system 4 comprises at least one detection device 110. FIG. 3 shows a possible embodiment of a picking station 48, for example for source containers 2 with left side wall 56, front wall 57 and top wall 58 removed for better clarity. The following description of the picking station 49 for source container 2 (source loading equipment) is analogously to the picking station 48 for target container 6 (destination loading equipment) to transfer, the picking station 48 to the first conveyor 21 and second conveyor 42 connects.

The picking station 49 for picking articles from source containers 2 (loading aids) by a picking person 7 comprises the frame or the housing with the side walls 56, the front wall 57 and / or the top wall 58, an automated loading equipment transport system for transporting source containers 2 a delivery area 109 and for transporting source containers 2 from the delivery area 109. The delivery area 109 is provided along a transport path 64 of the loading aid transport system and serves to provide a loading aid at the order picking station 49.

In the delivery area 109, an automated source container delivery device 61, which is arranged separately from the load carrier transport system, can also be provided, which comprises the order picking station 49. On the other hand, the loading equipment transport system may also include the source container pressing device 61.

In the embodiment shown, the loading equipment transport system can be an automated first source container transport device for transporting source containers 2 to the source container delivery area 109 (or possibly to the delivery device 61) and an automated second source container transport device for transporting source containers 2 from the source container delivery area 109 (or optionally from the tender device 61). The first source container transport device is formed by a first receiving unit 62 for at least one source container 2 and the second source container transport device by a second receiving unit 63 for at least one source container 2. The source container 2 is conveyed by means of the transport devices or receiving units 62, 63 along a transport path 64 between the first conveyor 20 and second conveyor 41, as indicated in Fig. 4 in dotted lines.

Both the first receiving unit 62 and the second receiving unit 63 are coupled to a common, reversible positioning drive 65. According to the embodiment shown, the positioning drive 65 comprises a drive station 66 with a single, reversible drive motor 67 (FIG. 4), in particular a reversible electric motor, and both

On the other hand, it is also possible that each traction mechanism drive 68, a drive motor 67 (not shown) is provided, wherein the drive motors 67 are electrically synchronized. The drive motor 67 may also be formed by a fluid drive, linear drive and the like. The drive station 66 is connected to the control device 51.

Each traction mechanism drive 68 comprises an endlessly circulating traction device which is guided around deflecting wheels 69 and a drive wheel 70. The drive wheels 70 of the traction mechanism drives 68 are coupled via a drive shaft 71 to the common drive motor 67. But just as well, each drive wheel 70 can be coupled to a drive motor 67. The deflection and drive wheels 69, 70 are mounted on the frame or on the side walls 56. The traction means are formed, for example, by a toothed belt, a chain or the like.

On the other hand, it is also possible for the first receiving unit 62 to be coupled to a first positioning drive and the second receiving unit 63 to be coupled to a second positioning drive. In this case, as described above, the positioning drives can each be coupled to a drive motor or to a common drive motor. The first receiving unit 62 for a source container 2 is supported on this mounted guide members 72, preferably on stationary guide arrangements 73. The guide arrangements 73 are arranged according to the embodiment shown on both sides of the first receiving unit 62 and extend parallel to each other between the first conveyor technology 20 and the tender s device 61 over a longitudinal portion of the transport path 64. Preferably, the guide assemblies 79 on the frame or attached to the side walls 56.

The first receiving unit 62 comprises a guide frame 74 with the guide members 72 and a receiving platform 75 projecting thereon for a source container 2, the guide frame 74 being connected to the traction mechanism drives 68 via fastening means 76, for example clamping connections and the like. As shown, the receiving platform 75 includes spaced-apart receiving forks protruding from the guide frame 74. The receiving platform 75 forms a receiving surface for at least one source container 2 and is provided with retaining elements 77 projecting on the receiving surface, against which a source container 2 can be supported when it loads on the receiving platform 75. Preferably, the receiving surface with respect to a horizontal plane and in the direction of the picking person 7 out by an angle of up to 45 °, for example 15 °, inclined downwards.

The second receiving unit 63 for a source container 2 is supported by guide elements 78 mounted thereon, preferably on stationary guide arrangements 79.

The second receiving unit 63 comprises a guide frame 80 (FIG. 5) with the guide members 78 and a receiving platform 81 connected thereto for a source container 2, the guide frame 80 being connected to the traction mechanism drives 68 via fastening means 82, for example clamping connections and the like is. The receiving platform 81 forms a receiving surface for at least one source container 2 and is provided with retaining elements 83 projecting on the receiving surface, against which a source container can be supported when it loads on the receiving platform 81. Preferably, the

Receiving surface with respect to a horizontal plane and in the direction of Kommissionierperson 7 out by an angle of up to 45 °, for example 15 °, inclined downwards. The guide arrangements 79 are arranged according to the embodiment shown on both sides of the second receiving unit 63 and extend parallel to each other between the second conveyor 41 and the Anlieungsvomchtung 61 over a length portion of the transport path 64. Preferably, the guide assemblies 79 on the frame or on the side walls 56 attached.

On the other hand, it is also possible, as not shown, that only a guide arrangement 79 is provided between the traction mechanism drives 68, which is arranged below the second receiving unit 63 and extends between the second conveyor 41 and the Anlieungsvomchtung 61 over a longitudinal portion of the transport path 64. In this case, only one guide member 78 can proceed, which is supported on the guide assembly 79.

As can be seen in the figures, it is advantageous if the guide arrangement (s) 79 forms in a guide section an elevation plane 84 or ramp-up slope (s) rising in the direction of the second conveyor 41. The slope of the Auffahrschräge 84 is between 5 ° and 30 °. To the guide portion 63 in a direction of movement of the second receiving unit 63 upstream guide sab cut and downstream guide sab cut connect, each forming a substantially horizontal guide plane 86, 87.

According to a preferred embodiment, the receiving platform 81 is pivotably connected to the guide frame 80 via a bearing axis 88 or pivotable about a bearing axis 88 relative to the guide arrangement (s) 79 and with the guide elements 78 extending parallel to the bearing axis 88. provided in particular training wheels.

According to this embodiment, it is possible that the receiving platform 81 guided on the adjusting movement along the transport path 64 between the Andienungsvomchtung 61 and the second conveyor 41 via the guide assembly (s) 79 and the (the) guide member (s) 78 such a bearing angle of the receiving surface 89 may change relative to a second conveying plane 90 of the second conveyor 41. If the receiving platform 81 with the guide member (s) 78 in the guide section of the guide arrangement (s) 79 forms an inclined driving plane 84, the receiving surface 89 and conveying plane 90 are substantially plane-parallel, as in FIG. 5 seen. Accordingly, the receiving surface 89 and conveying plane 90 include an angle of substantially 180 °.

If, however, the receiving platform 81 is located with the guide member (s) 78 in the guide section of the guide arrangement (s) 79, which forms a substantially horizontal guide plane 87, the receiving surface 89 and conveying plane 90 enclose an angle of less than 180 °, as shown in Fig. 4.

In other words, the source container 2 is tilted on its conveying movement between the arrival device 61 and the second conveyor 41 in the direction of movement 85, as shown in Fig. 8, before the transfer from the second receiving unit 63 to the second conveyor 41 in a transfer position in which a contact surface 91 of the source container 2 extends substantially parallel to the conveying plane 90.

In the transitional movement of the receiving platform 81 with the / the guide member (s) between the conveyor section, in which an inclined Auffahrebene 84 is formed, and the conveyor section, in which a horizontal guide plane 87 is formed, the swelling container 2 from the tilted transfer position in a Pickup situation slightly tilted back, in which initially one of the second conveyor 41 facing front edge of the source container 2 (loading equipment) touches the conveyor plane 90. Due to the continuous adjusting movement of the receiving platform 81 in the direction of the second conveyor 41, the footprint 91 of the source container 2 reaches the conveyor plane 90 for support.

As a result, even at a very high adjustment speed of the second receiving unit 63 or conveying speeds of the source container 2, a low-noise transfer of a source container 2 between the second receiving unit 63 and the second conveyor 41 can take place.

In Fig. 3, the stationary Andienungs device 61 is shown for a source container 2, which is preferably structurally separated from the receiving units 62, 63 is formed. This is along the transport path 64 between the first conveyor 20 and second conveyor 41 and includes on both sides of the transport path 64 at least one storage element 92 for a source container 2. The storage elements 92 are by actuators 93 between a starting position (Fig. 3, 4, 7, 8) and a receiving position (FIGS. 5, 6). The storage elements 92 and actuators 93 are mounted on the frame, in particular the side walls 56.

According to the illustrated embodiment, two left-hand parking elements 92 and two right-hand parking elements 92 are provided on both sides of the transport path 64. Each shut-off element 92 is coupled to an actuator 93. But it is also possible that the left Abstellelemente 92 are coupled to a single actuator 93 and the right Abstellelemente 92 with a single actuator 93. Also, the left and right shutoff elements 92 can be coupled with only a single actuator 93. The mechanical coupling between the pivot axes of the Abstellelemente 92, for example, by a Zugmit- tel, such as toothed belts and the like., Or link rods done. The / the actuator (s) 93 are formed for example by reversible, electrical or fluidic actuators.

In the starting position of the storage elements 92 (FIGS. 3, 4, 7, 8), a source container 2 can be moved past the storage elements 92, while in the receiving position (FIGS. 5, 6) a source container 2 can be placed on the storage elements 92. In the receiving position, a source container 2 is in a delivery position, therefore in a suitable for the Kommissi- person 7 removal position for articles. In the receiving position, a destination container 6 is in a delivery position, therefore in a loading position suitable for the order picking person 7, in which the articles removed from the source container 2 can be placed in the destination container 6.

The shut-off elements 92 each comprise a parking tongue 94 and a positioning element 95 projecting substantially perpendicular thereto, as indicated in FIG. 8. In the delivery position of the source container 2 or order container 6, the latter is centered between the positioning elements 95 of the shut-off elements 92 which are respectively moved into the receiving position and bears on the set-off tongues 94. The storage elements 92 are, for example, angle levers, which are in each case rotatable about a pivot axis about an adjustment angle of preferably 90 ° back and forth and in each case form the parking tongue 94 in a lever section adjacent to the transport path 64. As can be seen from FIGS. 4 to 8, the first receiving unit 62 for a first source container 2 and the second receiving unit 63 for a second source container 2 are motion-coupled via the single positioning drive 65 and both simultaneously carry out an adjustment movement in the same direction either in a first direction of movement 85 in FIG Clockwise (Fig. 5) or in a second direction of movement 85 in the counterclockwise direction (Fig. 7).

In this case, the first receiving unit 62 can be adjusted with the positioning drive 65 between a transfer position 96 (FIGS. 6, 7) on the first conveyor 20 and a transfer position 97 (FIG. 4) on the delivery device 61 or in the delivery area 109. The transfer position 96 is located at a first height level below a first conveying plane 98 of the first conveyor 20. The transfer position 97 is at a second height level just above a delivery position 99 (FIG. 5) or delivery level for a source container 2, in order to ensure unobstructed adjustment of the depositing element 92 to admit. The transfer position 97 is above the transfer position 96. Optionally, the transfer position 97 and delivery position 99 can correspond with respect to a height level. Preferably, the delivery level is inclined downwards with respect to a horizontal plane and in the direction of the picking person 7 by an angle of up to 45 °, for example 15 °, so that a particularly ergonomic order picking is possible for the picking person 7. In this case, the second receiving unit 63 can be adjusted with the positioning drive 65 between a transfer position 100 (FIG. 6) on the delivery device 61 or in the delivery region 109 and a transfer position 101 (FIG. 4) on the second conveyor 41. The take-over position 100 and transfer position 101 are essentially at the same height level above the first conveyor 20. In the take-over position 100, the receiving surface 89 on the second receiving unit 63 is above the delivery position 99 or delivery level for a source container 2. If appropriate, in the takeover position 100 Receiving surface 89 and delivery level with respect to a height level match. In the transfer position 101, the receiving surface 89 at the two th conveyor 41 below second conveyor plane 90, as shown in Fig. 4. As a result, a source container 2, when it has been transferred to the second conveyor 41, can be moved at a very high conveying speed independently of the adjusting movement of the second receiving unit 63. Accordingly, a decoupling of the conveying movement of a source container 2 and the adjusting movement of the second receiving unit 63 for renewed movement into the transfer position 100 is possible.

After the first receiving unit 62 exclusively performs a vertical movement and the second receiving unit 63 only a horizontal movement, a particularly fast container change between the first conveyor 20 and second conveyor 41 is possible. A decoupling of the adjustment movements is made possible by the tender device 61.

As can be seen in the figures, the first conveyor 20, 21 comprises a transfer device 102 in a first delivery section facing the delivery device 61 and a delivery device 103 in a second delivery section facing away from the delivery device 61. The driven delivery device 103 comprises conveying elements and serves as a buffer path , in particular Horizontalpufferbahn with buffer storage spaces for a variety of source containers 2 and target containers 6. The conveyor can this tion a stowage tion allow. The transfer device 102 forms a parking space for a source container

2 or order container 6 and comprises at least one preferably driven conveying element. According to the embodiment shown, the conveying elements of both the transfer device 102 and the conveying device 103 are formed by a roller conveyor. As shown in FIG.

3, a width of the conveying element of the transfer device 102 is selected such that the receiving forks of the receiving platform 75 on opposite longitudinal sides of the

Transfer device 102 can be moved past. The transfer device 102 and conveying device 103 form the horizontal first conveying plane 98. The first conveying plane 35 of the distribution system 3; 8 and the first conveying plane 98 are preferably in a horizontal plane.

As can be seen in the figures, the second conveyor 41, 42 in a first conveyor section 61 facing the first conveyor section comprises a transfer device 104 and in a the delivery device 61 facing away from the second conveyor section a conveyor The driven conveying device 105 comprises conveying elements and can serve as a buffer track, in particular a horizontal buffer track with buffer memory locations, for a multiplicity of source containers 2 or target containers 6. The conveyor device can for this purpose allow a storage function. The transfer device 104 forms a parking space for a source container 2 or order container 6 and comprises at least one driven conveying element. According to the embodiment shown, the conveying elements of the conveying device 105 are formed by a roller conveyor. The conveying elements of the transfer device 104 are formed by in the direction of the conveying movement of the source container 2 and target container 6 parallel conveyor belt.

The transfer device 104 extends along the transport path 64 in the direction of the Andienungsvorrichtung 61 and forms in the direction of the tender s device 61 inclined downwardly extending conveyor plane 90 from. Preferably, the conveying plane 90 is inclined relative to a horizontal plane by an angle of up to 30 °. The conveying device 105 forms a horizontal conveying plane, which lies with the second conveying plane 40 of the distributing system 36 in a horizontal plane.

As shown in FIGS. 4 to 8, the source containers 2 and target containers 6 are preferably conveyed from below, on the first conveying plane 35, 98, via the first receiving unit 62 to the height level of the delivery device 61 above the first conveyor 20, 21 moves and after a completed picking process on the second receiving unit 62 taken over by the delivery device 61 and promoted by this to the second conveyor 41, 42. On the other hand, it is also possible that the conveying direction is reversed. The source container 2 or target container 6 are conveyed from above, on the second conveyor plane 40, 90, taken over the second receiving unit 63 of the second conveyor 41, 42 and conveyed to the tender device 61. After a completed order picking process, the source container 2 or destination container 6 is taken over by the first receiving unit 62 adjusted to the height level of the delivery device 61 and conveyed to the first conveyor 20, 21. Accordingly, the source containers 2 and target container 6 are conveyed on the third distribution system 36 to the order picking 5 and on the first distribution system 3 and, if appropriate, second distribution system 8 are again conveyed away from the order-picking systems 5.

In the following, the method for picking articles from source containers 2 into target containers 6 will be described with reference to FIGS. 1, 2, 4 to 8.

If a picking order has been recorded electronically on a computer system, at least one source container 2 for this picking order is removed from the shelf storage 1 via the automated conveyor system 12, 16 and transferred to the first conveyor system and, if appropriate, from this to the second conveyor system. The source container 2 is at the distribution system 3, 8 to one of the picking 4 jobs; Promoted 9 and discharged from the conveyor system by means of one of the off devices 29 on the first conveyor 20. For this purpose, the discharge devices 29 and the conveyor system are connected to the control device 51, which in turn coordinates the allocation to the order-picking systems 5. The source containers 2 provided with the data carriers 52, 53 can be detected automatically by reading out the data of a first data carrier 52 at the detection devices 50. As a result, the transport routes and locations for the source containers 2 are traceable. Likewise, at least one target container 6 is conveyed to the picking station 49, to which the source container 2 is provided, for this picking order. The destination containers 6 provided with the data carriers 52, 53 can be automatically detected by reading out the data of a first data carrier 52 at the detection devices 50. As a result, the transport routes and locations for the destination container 6 are traceable.

The source containers 2 or target containers 6 provided with the data carriers 52, 53 can be automatically detected by reading the data of a data carrier 52, 53 on the detection device 108. As entered in FIG. 2, the source container 2 or destination container 6, when conveyed on the conveyor 20, 21 to the order picking station 48, 49, moves past the detection device 108 and thereby automatically data of the second data carrier 53 or data of the identification System detected and the control device 51 transmitted. If the data can be read from the second data carrier 53 at the detection device 108 and thus the source container 2 or target container 6 identified by the control device 51, an identification signal is transmitted to the control device 51 which in turn drives the drive station 66 in a first operating mode, in particular in FIG Automatic mode controls, so that the picking of articles can be carried out. In the first operating mode, the drive station 66, in particular the drive motor 67, is acted on by the control device 51 with a normal operating signal.

The loading aid transport system, in particular its receiving units 62, 63, is thereby controlled in the first operating mode, as described with reference to FIGS. 4 to 8 for source container 2. As already described above, the conveying movement can also be reversed, but will hereinafter be referred to a preferred conveying movement of the source container 2 from bottom to top. The same applies to the order container. 6

As can be seen in FIG. 4, the second receiving unit 63 is located in the transfer position 101, in which a first source container 2.1 has already been transferred to the second conveyor 20. The first receiving unit 62 is located in the transfer position 97, in which a second swelling container 2.2 is transferred to the depositing elements 92 which are still to be adjusted into the receiving position (FIGS. 5, 6). A third source container 2.3 is already conveyed back to the picking station 5 on the first conveyor 20.

If now the first receiving unit 62 and the second receiving unit 63 are moved via the common positioning drive 65 from their transfer positions 97, 101 in the direction 85 in their takeover positions 96, 100, as shown in Fig. 5, the second source container 2.2 on the already in the receiving position adjusted Abstellelemente 92 discontinued. In the meantime, the first source container 2.1 is carried away on the second conveyor 41, the third source container 2.3 is provided at the front end of the first conveyor 20, and a fourth source container 2.4 is conveyed to the order-picking station 5 on the first conveyor 20. After settling on the storage elements 92, the second source container 2.2 is located in its delivery position 99 on the delivery device 61 or in the delivery region 109, in which items are taken from the source container 2.2 in accordance with a picking order and in a destination container 6 provided at the order picking station 48 be filed. Also it is possible that the articles are in one, on one in addition to the picking station 49 provided buffer space provided loading equipment, such as a pallet, are stored.

FIG. 6 shows the first receiving unit 62 in the take-over position 96, in which the third source container 2.3 can be transferred from the first conveyor 20 to the first receiving unit 62. The second receiving unit 63 is in the transfer position 100, in which the second source container 2.2 has been lifted from the storage elements 92, which are still adjusted to the receiving position. Meanwhile, the fourth source container 2.4 is conveyed toward the front end of the first conveyor 20.

According to FIGS. 7 and 8, the storage elements 92 have been adjusted to the starting position, so that the second source container 2 or third source container 2 can be moved between the storage elements 92. Thus, the first receiving unit 62 can be moved again from the transfer position 96 into the transfer position 97, in which the third source container 2.3 is transferred to the still in the receiving position to be adjusted Abstellelemente 92. Meanwhile, the second source container 2.2 is conveyed away by means of the second receiving unit 63 to the second conveyor 41. The fourth source container 2.4 is provided at the front end of the first conveyor 20 and a fifth source container 2.5 is conveyed towards the front end of the first conveyor 20.

Accordingly, it can be seen that the receiving unit 62, 63 oscillates via the positioning drive 65 along the transport path 64 between the transfer position 96 for a source container 2 or destination container 6 provided on the first conveyor 20, 21 and the transfer position provided on the second conveyor 41, 42 101 for a source container 2 and destination container 6 and oscillating between this takeover and transfer position 96, 101 and a transfer and takeover position 97, 100 provided on the tender s device 61 and provided in delivery area 109 transfer and takeover position 97, 100 , If the conveying movement of the source container 2 or destination container 6 is reversed from top to bottom, then the transfer position 96 defines a transfer position 96 and the transfer position 101 a transfer position 101. Likewise, the transfer position 97 defines a transfer position 97 and the transfer position 100 a transfer position 100. On the other hand, if the data of the second data carrier 53 or data of the identification system can not be detected, if the source container 2 or target container 6 is conveyed on the conveyor 20, 21 to the picking station 48, 49 and past the detection device 108, the control device 51 becomes transmits a false reading signal, which in turn acts on the drive station 66 with a switching signal. In this way, the first operating mode, in particular the automatic mode, is interrupted and a "modified" container provisioning process is started according to a second operating mode, so that the order picking of articles can be carried out only after a subsequent identification of the source container 2 or target container 6. For this subsequent identification the additional detection device 110 is provided for detecting the first data carrier 52. The data of the identification system can not be detected if, for example, the second data carrier 53 has been damaged by chemical and / or mechanical stress or if the second data carrier 53 is no longer present at all Control device 51 interrupts the first operating mode (normal operation) with the switching signal in the second operating mode, in the latter case the drive station 66, in particular the drive motor 67, from the control device 51 with a normal operation ebssignal is applied. The drive station 66, in particular the drive motor 67, is acted upon by the control device 51 in the second operating mode (read-detection operation) with the switch-over signal.

A misread signal is transmitted to the control device 51 immediately after the source container 2.1 has passed the detection device 108 with the damaged data carrier 53, whereupon the loading accessory transport system is switched into a second operating mode.

The loading equipment transport system, in particular its receiving units 62, 63, is controlled in a second operating mode, as described in accordance with a first embodiment with reference to FIGS. 9 to 12 for source container 2. As already mentioned above, the conveying movement can also be reversed, but is subsequently referred to a preferred conveying movement of the source containers 2 from the bottom to the top. The same applies to the order container. 6 In FIG. 9, a source container 2.1, which could not be identified due to the damage of the second data carrier 53 by the detection device 108 (FIG. 2), is located on the second receiving unit 63. The loading aid transport system is now activated in the second operating mode in such a way that the source container 2.1 is moved via the loading aid transport system, in particular the second receiving unit 63, into a detection position 111 (FIG. 10) and remains there until the first data carrier 52 is detected was entered as in Fig. 9 with the arrow 85. The detection position 111 preferably lies along the transport path 64 (FIG. 4) between the first conveyor 20 and the second conveyor 4.

On the one hand, the control device 51 can be designed such that it automatically generates the switching signal for driving the drive station 66 in the second operating mode and, accordingly, the loading aid transport system is switched to the second operating mode. In this case, in the second operating mode, the loading aid transport system is actuated in such a way that the source container 2.1 is moved by the loading aid transport system from a detection position 112 (FIG. 9) in the region of the first conveyor device 20 or detection device 108 (FIG. 2) into the detection position 111 (Figure 10) is moved on the load carrier transport system. Additional prompts generated by the control device 51 and displayed on the output unit 55 are not to be confirmed.

On the other hand, it can also be provided in the second operating mode that the control device 51 generates an error message or a prompt for the order picking person 7 and displays it at the output unit 55. The input request is output at the optical and / or acoustic output unit 55; for example, the order picking person 7 is requested to initiate the second operating mode by confirming the input request to the input unit 54. If the input request has been confirmed, the switching signal for activating the drive station 66 is generated and, accordingly, the loading aid transport system is switched to the second operating mode and controlled such that the source container 2.1 is moved from a detection position 112 in the area of the first conveyor 20 Device 108 (Figure 2) is moved to the detection position 111 (Figure 10) on the load carrier transport system. In the detection position 111 (FIG. 10 or FIG. 2 at the left picking station 49), the source container 2.1 is positioned along its transport path 64 relative to the delivery region 109 or the recess 60 such that the data of the first data carrier 52 can be detected.

The data of the first data carrier 52, for example a container identification number, can be read by the picking person 7 after a first execution and can be recorded manually via the input unit 54. The input unit 54 in this case forms the detection device 110, which is connected to the control device 51 and transmits a subsequently generated identification signal.

The data of the first data carrier 52, for example a container identification number, can be automatically read out according to a second embodiment via the mobile detection device 110 (hand scanner) serving the picking person 7, whereupon the control device 51 from the detection device 110 generates a subsequently generated identification signal is transmitted. A manual input of data can be omitted.

If the data of the first data carrier 52 were detected and subsequently identified by the control device 51 of the source container 2.1, the source container 2.1 is automatically moved via the loading aid transport system, in particular the second receiving unit 63 from the detection position 111 into the delivery region 109, in which missioning can be done, as entered in Fig. 10 with the arrow 85. It would also be conceivable that the movement of the source container 2.1 from the detection position 111 in the delivery area 109 by the picking person manually done, the source container 2.1 while auflastet on the loading equipment transport system, in particular the second receiving unit 63, but the drive station 66 is switched off is.

On the one hand, the control device 51 can be embodied such that, in the second operating mode, after the data of the first data carrier 52 has been acquired, it automatically generates an actuating signal for driving the drive station 66 and, accordingly, the loading aid transport system is actuated to move the source container 2.1 through the Loading equipment transport system from the detection position 111 in the Andienungsbereich 109 to move. Additional prompts generated by the controller 51 and displayed on the output unit 55 are not to be confirmed.

On the other hand, it can also be provided in the second operating mode that the control device 51 generates an error message or a prompt for the picking person 7 after the data of the first data carrier 52 has been acquired and is displayed on the output unit 55. The input request is output at the optical and / or acoustic output unit 55; for example, the order picking person 7 is requested to confirm the subsequent recording of the data at the input unit 54. Once the data have been read in at the input unit 54, an actuating signal for actuating the drive station 66 is generated and, accordingly, the loading equipment transport system is actuated in order to move the source container 2.1 from the detection position 111 into the delivery area 109 by the loading equipment transport system. The source container 2.1 is provided for picking on the second receiving unit 63 in the delivery area 109, as shown in Fig. 11. The source container 2. 1 is in its delivery position 99. Settling of the source container 2. 1 on the application device 61, if one exists, is not necessary. For the order picking process, the picking person 7 is shown the removal quantity at the output unit 55 (FIG. 2) and the corresponding quantity of articles is picked from this into the destination container 6. The end of the picking process is acknowledged by the picking person 7 at the input unit 54 (FIG. 2). After the picking operation is completed, the source container 2.1 is conveyed away from the loading equipment transport system, in particular the second receiving unit 63, from the delivery area 109 or from the delivery position 99 to the second conveyor 41, as shown in FIG. Meanwhile, the first receiving unit 62 is moved with the second source container 2.2 from the transfer position 96 to the transfer position 97, in which the second source container 2.2 is transferred to the still in the receiving position to be adjusted Abstellelemente 92. A third source container 2.3 is provided on the first conveyor 20. The loading equipment transport system, in particular its receiving units 62, 63, can also be controlled in a second operating mode, as described in accordance with a second embodiment with reference to FIGS. 13 and 14 for source containers 2. The same applies to the order container 6. According to this embodiment, the frame or the enclosure, in particular the front wall 57 is provided with a viewing window 113 through which can be viewed on the first disk 52.

The control device 51 in turn interrupts the first operating mode (normal operation) in the second operating mode, in the latter case the drive station 66, in particular the drive motor 67, is supplied with a normal operating signal. The drive station 66, in particular the drive motor 67, is acted upon in the second operating mode (read-detection operation) by the control device 51 with the switch-over signal.

In Fig. 13, there is a source container 2.1 in Andienungsbereich 109 in a detection position 111. According to the embodiment shown, the source container 2.1 is deposited on the Abstellelementen 92 and located in the tender position 99. The source container 2.1 could due to the damage of the second Data carrier 53 by the detection device 108 (Figure 2) are not identified. The loading aid transport system is now controlled in the second operating mode such that the source container remains 2.1 in the detection position 111 until the first volume 52 has been detected.

On the one hand, the control device 51 can be embodied such that in the second operating mode it automatically generates the switching signal for activating the drive station 66 and, accordingly, the loading aid transport system is switched to the second operating mode. In this case, in the second operating mode, the loading aid transport system is actuated in such a way that the source container 2.1 is moved by the loading aid transport system from a detection position 112 in the region of the first conveyor device 20 or detection device 108 (FIG. 2) into the detection position 111 (FIG. 13). is moved in the delivery area 109. Additional prompts generated by the control device 51 and displayed on the output unit 55 are not to be confirmed. On the other hand, it can also be provided in the second operating mode that the control device 51 generates an error message or a prompt for the order picking person 7 and displays it at the output unit 55. The input request is output at the optical and / or acoustic output unit 55; for example, the order picking person 7 is requested to initiate the second operating mode by confirming the input request to the input unit 54. If the input request has been confirmed, the switching signal for activating the drive station 66 is generated and, accordingly, the loading aid transport system is switched to the second operating mode and controlled such that the source container 2.1 is detected from a detection position 112 in the area of the first conveyor 21 Device 108 (Fig. 2) is moved to the detection position 111 (Fig. 10) in the Andienungsbereich 109.

In the detection position 111 (FIG. 13 or FIG. 2 at the right-hand picking station 49), the source container 2.1 is positioned along its transport path 64 relative to the delivery area 109 such that the data of the first data carrier 52 can be detected via the viewing window 113.

The data of the first data carrier 52, for example a container identification number, can be automatically read out in a second embodiment via the mobile detection device 110 (hand scanner) serving the picking person 7, whereupon the control device 51 is provided by the detection device 110 with an subsequently generated identification signal is transmitted. A manual input of data can be omitted.

After the source container 2 has subsequently been identified, picking can take place. The end of the picking process is acknowledged by the picking person 7 at the input unit 54 (FIG. 2). After the picking process is completed, the source container 2.1 is conveyed from the loading equipment transport system, in particular the second receiving unit 63 of the Andienungsbereich 109 and the detection position 111 to a transfer position 101 and the second conveyor 41 from, as shown in Fig. 14 , Meanwhile, a third source container 2.3 is provided on the first conveyor 20.

The loading equipment transport system, in particular its receiving units 62, 63, can also be controlled in a second operating mode, as described in accordance with a third embodiment with reference to FIGS. 15 and 16 for source container 2. The same applies to the order containers 6.

According to this embodiment, the picking station 49 is provided within the frame or housing with the detection device 110 which is arranged such that this data of the first data carrier 52 of a source container 2 located in the delivery area 109 can be detected. In this case, the still "unidentified" source container 2 with its first data carrier 52 is conveyed past the picking position 111 in the delivery region 109 and thereby on the stationary acquisition device 110 immediately before a picking operation, so that the data carrier 52 can be automatically detected or the enclosure, in particular attached to the front wall 57 stationary.

The control device 51 interrupts again in the second operating mode, the first operating mode (normal operation), in the latter, the drive station 66, in particular the drive motor 67, is acted upon by a normal operating signal. The drive station 66, in particular the drive motor 67, is acted upon by the control device 51 in the second operating mode (read-detection operation) with a switching signal.

In Fig. 15, there is a source container 2.1 in the delivery area 109 in a detection position 111. According to the embodiment shown, the source container 2.1 is deposited on the storage elements 92 and located in the tender position 99. The source container 2.1 could due to the damage of the second data carrier 53rd are not identified by the detection device 108 (Figure 2). The loading aid transport system is now controlled in the second operating mode such that the source container remains 2.1 in the detection position 111 until the first volume 52 has been detected. Again, the switching signal in the second mode of operation may be generated either automatically by the controller 51 or upon an error message, as described above in FIGS. 13 and 14.

After the source container 2 has subsequently been identified, picking can take place. The end of the picking process is acknowledged by the picking person 7 at the input unit 54 (FIG. 2).

Thereafter, the source container 2.1 is conveyed away from the loading aid transport system, in particular the second receiving unit 63, from the delivery area 109 or from the detection position 111 to a transfer position 101 or to the second conveyor 41, as shown in FIG. 16.

If the first data carrier 52 is also damaged, for example by chemical and / or mechanical stress, or if the first data carrier 52 is no longer present, the data of the first data carrier 52 or data of the identification system can not be detected. Since the identification system of the loading aid 2, 6 can have more than the two data carriers 52, 53 shown, for example, three or four data carriers, which in turn are arranged on other surface portions of the loading aid 2, 6, in particular the third and / or fourth side wall, is at least on the first conveyor system to the detection device 50 an identification, for example by the third disk possible.

If the loading aid 2, 6 could not subsequently be identified via the detection device 110, the loading aid 2, 6 is conveyed out of the detection position 111 directly from the picking station 48, 49. The "unidentified" load support 2, 6 is conveyed to the third conveyor system via the conveyor 41, 42 and from there to an error handling station 114 (Figure 1) .The error handling station 114 comprises a conveyor track, for example a roller conveyor, belt conveyor, and the like., Which connects to the third conveyor system and third distribution system 36. The "unidentified" loading aid 2, 6 can be automatically transferred to the error handling station 114 via a discharge device 115. At the error handling station 114, the loading aid 2, 6 can be provided with new data carriers, for example new barcode labels can be glued to the side walls.

Finally, it should also be noted that the embodiment of the picking station shown may not be seen as limiting the invention. Rather, any design for the picking station is possible, as they are known for example from EP 2 098 464 AI and EP 2 050 695 AI. Also, the first conveyor 20, 21 and second conveyor 40, 41, to which the respective order picking 48, 49 connect, not on top of each other, but in a horizontal plane.

The exemplary embodiments show possible embodiments of the method for providing loading aids, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but rather various combinations of the individual embodiments are possible with each other and this variation possibility due to Teaching for technical action by objective invention in the skill of those working in this technical field is the expert.
