Abstract

A method for the order-picking of articles at an order-picking station, in which method the source containers (5) are conveyed in an arbitrary order towards a removal point (33) and the destination containers (27) are provided in a sorting buffer (36) comprising buffer points (39) in front of a single loading point (35). In order to process different order lines, once an article belonging to a first order line has been placed in a first destination container, said container is conveyed back to the sorting buffer and is temporarily buffered at a sorting point (42) until a source container comprising an article belonging to a second order line is conveyed to a buffer track section (23) provided upstream of the removal point. In order to process different order lines, once an article belonging to a second order line has been placed in a second destination container, said container is conveyed back to the sorting buffer, and is moved via a second sorting point to one of the buffer points, and then to the loading point, provided that a source container comprising an article belonging to a second order line has already been conveyed to the buffer track section. The invention also relates to an order-picking station.

Description

Method for picking articles and picking station

The invention relates to a method for picking articles, in particular storage articles or returned goods, and a picking station for carrying out the method, as described in the preambles of claims 1, 11, 19 and 24.

WO 2011/103404 A1 discloses a method for manual picking of articles at a picking station. The source containers are removed from a warehouse, transported to the order picking station and finally provided on a (single) picking station. The target containers are stored in a sorting buffer and delivered from the sorting buffer in an order on a conveyor and finally provided on a (single) loading place sequentially (consecutive). The transport of the source containers from the warehouse to the take-off location and the transport of the destination containers from the sorting buffer to the loading location are coordinated so that a source container and a destination container arrive at an order approximately simultaneously at the picking location and loading location. The picking person can remove from the source container, which is provided on the picking place, and deposit this article in the destination container, which is provided on the loading place. The destination container is returned from the loading point to the sorting buffer, provided that the order assigned to this destination container still contains an unprocessed order line. The order picking person always has access to a single source container and a single target container. Such picking stations are also called 1: 1 picking workstations. These are characterized by a high picking performance (about 1,000 article accesses per hour) and a low number of incorrect picking orders. The sorting buffer of the known picking system comprises storage racks and at least one movable between the storage shelves storage control unit, with which the target containers can be stored on Puff erpl et cetera and swapped out of the buffer locations. A disadvantage is the high mechanical complexity of the sorting buffer and the complexity of the control device. Furthermore, the target containers must cover long transport routes, which is why the provision of the target container takes a relatively long time.

EP 1 767 472 A1 discloses a method for manual picking of articles at a picking station. The source containers are outsourced from a warehouse, transported to the picking station and finally provided on at least two sampling sites. The target containers are stored in a sorting buffer and delivered in a sequence from the sorting buffer on a conveyor technology and finally provided on at least two loading locations side by side. The picking person has access to several source containers and several destination containers at least over shorter operating phases. Thus, in principle, a high order picking performance can be achieved, however, is expected with a higher number of Fehlkommissionierungen. Furthermore, the target containers must cover long transport routes, which is why the provision of the target container takes a relatively long time.

EP 2 098 464 B1 discloses a method for manual picking of articles at a picking station. The source containers are repeatedly circulated on a circulation conveyor device of the order picking person until a predetermined number of articles are picked from the respective source container into the destination containers. The target containers are repeatedly circulated at several Umlauffördervorrichtungen the order picking fed so long until the respective in circulation target container is picked with the articles from the supplied source container in the desired number. The picking person always has a source container and several target containers in the access.

Likewise, EP 3 015 404 A1 discloses a method for manual order picking or return storage of articles at a picking station, in which a picking area is subdivided into sequential picking zones and each picking zone is assigned a plurality of picking positions arranged next to one another which ever a source container is provided. The source containers contain different articles. Target container groups are successively moved through the picking zones on a destination container conveyor. An order is divided into partial orders and the source containers are fed to the respective destination container group according to the partial orders. The picking person always has several source containers and several destination containers in the access.

From EP 2 173 644 B1, a method for picking returned goods at a picking station is known, in which the returned goods are provided at a loading station and every returned good is recorded. The returned goods are transported on a return conveyor from the loading station to the commissioning station. For each returned product, a source container is identified, in which the returned goods are stored. The source container is removed from a warehouse while the returned goods are transported to the picking station.

An object of the invention is therefore to specify an improved method for commissioning articles, in particular stock items or returned goods, and an improved picking station for carrying out the method. In particular, an efficient commissioning at the picking station is to be made possible.

The object of the invention is achieved in that a first target container for processing different order lines is transported to at least one order after placing an article to a first order line back into the sorting buffer and buffered on a first sorting at least temporarily until a source container with an article is conveyed to a second order line in a puff provided upstream of the picking station, and said first destination container can be moved from the first sorting station to one of the buffer locations and then to the loading station after the source container with an article moves to a second order line in the Buffer section was transported, and transported a second destination container for processing different order lines to at least one order after depositing an article to a first order line back into the sorting buffer and is moved via a second sorting on one of the buffer locations and then to the loading point, if a source container with an article to a second order line has already been transported in a provided upstream upstream of the sampling puff section.

Furthermore, the object of the invention is achieved in that the sorting buffer on a first conveyor in a dispensing direction successively arranged buffer locations and on a second conveyor in a

The return direction of sorting stations arranged one behind the other and the sorting stations with the buffer The delivery device with the single loading point is formed on a fourth conveying device, wherein the first conveying device and the second conveying device are connected to one another via the fourth conveying device in order to at least target the target containers for processing different order lines order a request from the sorting buffer to the loading station and request from the loading point to the sorting buffer, and wherein the first conveying device at least one conveying means for transporting

Destination container and the second conveyor device have at least one conveying means for transporting the destination containers, and wherein the buffer stations and the sorting stations are assigned conveying means for transporting the destination containers, and a control unit controls the conveying means selectively and in such a way that the destination containers are sorted in the sorting buffer in an order, which is determined depending on the order in which the source containers are provided at the picking location, and that a source container and a destination container arrive at an order at about the same time at the picking place and loading place.

The sort function is taken over by the sort buffer. In this case, a small number of destination containers are sorted in comparison to the number of source containers. The sorting buffer is directly in the vicinity of the loading point. The target containers can be transported to the loading site very quickly. Specifically, the sorting buffer realizes the sorting function of the destination containers, the provision of the destination containers in the sorted order and the transport of the destination containers from the sorting buffer and into the sorting buffer. For this purpose, standardized conveyors are used, which work reliably. In the sorting buffer, the transport of the target containers preferably takes place on a horizontal transport plane, which is formed by the conveying means. In a preferred embodiment, the articles "article-like" and in the target containers the articles "order-pure" are added to the source container. Therefore, a single article type is contained in a source container and a single job is contained in a destination container. However, in order to increase / maximize the article assortment in the warehouse / to optimize the sort buffer, source containers may each contain different article types and / or the destination containers may each contain different orders. An order comprises an order line or several order lines. This is made possible by receiving compartments in the source container and / or target container.

The picking station comprises a single take-off location for a source container and a single loading location for a destination container. As a result, picking can be reduced to a minimum, if the picking is done manually. Likewise, the picking person hardly needs to move from the place.

It also proves to be an advantage if the following procedural measures are carried out:

Outsourcing of the source containers from the warehouse by means of a source container distribution system with at least one storage operating device and a source container conveyor between the warehouse and the picking station, wherein the source container conveyor at least the Pufferstreckenab section for transporting the source container to the sampling includes

Transport of the source container on the source container conveyor of the at least one storage and retrieval device to the sampling in an unordered (chaotic) order, and

Determining the disordered (chaotic) sequence of the source containers, which are required for processing of different order lines to at least one order, at a sequence determination point, which lies along the transport path between the at least one storage and retrieval unit. Although the required source containers for processing the order lines are supplied to the picking place in a disordered order, this order is detected at the order determination point. The target containers in the sorting buffer determine which source containers have to be swapped out. The destination containers are sorted in and through the sorting buffer in an order determined by the order of the source containers. It is advantageous that the requirement for the sequence in which the source containers are transported to the picking location is low, and thus a high removal performance is achieved. The picking station can essentially be supplied with source containers without interruption. In addition, the complexity of controlling the outsourcing process is reduced.

An additional increase in performance (number of accesses to articles per hour) can be achieved if the following process steps are carried out: determination of a modified sequence of the source containers, in which the

Source container to be transported to the picking place,

Changing the order of the source containers in the modified order by discharging at least one preceding source container from the buffer to an alternate buffer to bypass at least one sequential source container at the at least one source container in the escape buffer and by returning the at least one source container Source container from the escape buffer on the Pufferstreckenab section to rearrange the at least one source container from the escape buffer the at least one source container on the buffer section section,

Sequentially providing at least some of the source containers at the picking location in the modified order. It can be provided that the source container distribution system has an adjoining the buffer section Ausweichpuffer with a funding and the control unit is configured to evaluate the order of the source containers, which are required for processing of different order lines to at least one order, and determining a modified order in which the source containers are to be transported to the take-off location, and the control unit controls the conveyor to eject at least one preceding source container from the puff section to the escape buffer to at least one subsequent source container to move past the source container in the escape buffer, and then to inject the at least one source container from the escape buffer onto the buffer path section.

According to one embodiment of the invention, the following method steps are possible:

Providing a first source container on the loading site for sequentially processing at least one first order line with a plurality of articles for a first order,

Removing an article from the first source container, which is provided at the picking place, and depositing this article in a first destination container, which is provided on the loading place, according to the first order, if this article can be stored in the first destination container,

Triggering a control signal after the last removal of an article from the first source container or after it has been determined that an article in the first destination container can not be stored, with which

a conveyor device of a source container distribution system arranged between the removal station and the puff is controlled by a control unit in such a way that the first source container is conveyed from the removal station to the puff section, and

the puff-extending section and a conveying means on the picking station are controlled by the control unit such that a second source container is transported to the picking station for processing one or more order lines to a second order, a conveying means on the loading place and a conveying means of a destination container distribution system are controlled by the control unit in such a way that the first target container is transported away from the loading place and a second target container is transported to the loading place,

Providing the second source container at the picking location for processing at least one or more order lines to the second order,

Removing an article from the second source container, which is provided at the picking place, and depositing this article in a second destination container, which is provided on the loading place, according to the second order,

Transfer of the first source container from the conveyor to the buffer section,

Transport of the first source container from the Pufferstreckenab section to the sampling place,

Repeatedly providing the first source container at the picking location to pick the remaining items of the first order line,

Taking an article from the first source container, which is provided on the picking place, and depositing the article in a second destination container, which is provided on the loading place, according to the first order.

It also proves advantageous if the following method steps are carried out:

Providing a destination container distribution system with the sorting buffer and a destination container conveyor system for transporting empty destination containers, bypassing the sorting buffer to the loading location,

Identify an empty destination container and assign it to a captured order Requesting and transporting the empty target container to the loading point, after the triggering of a control signal after the last removal of an article from the first source container, with which the target container conveyor is controlled by the control unit such that the empty target container to the loading point for processing the at least one first order line is transported to the first order.

It can be provided that the source container distribution system has a conveying device adjoining the buffer section section with a conveying means and the control unit is set up to process a control signal after the last removal of an article from the source container, and the control unit based on the control signal Promotes conveyor to promote the first source container after removing the at least one article from the sampling site on the Pufferstreckenab section. These mentioned method measures allow an efficient order-picking process in which the loading volume of the destination containers can be used to the maximum and the picking person decides which article and / or which number of articles can still be picked in a destination container. If a control signal is triggered by the picking person, for example by pressing an acknowledgment key, the (full) first destination container is transported away and an (empty) second destination container is automatically provided in order to process the first order. During the provision of the (empty) second destination container, a second order can be processed. Thereafter, the first source container is repeatedly provided and the first order processed. Due to the possibility of repeated provision of the first source container, a "time-consuming" return operation of the first source container into the storage and retrieval operation of the first source container from the warehouse is not necessary, thus also less burden on the source container distribution system.

The following method measures can also be implemented in an advantageous manner: acquisition of at least one article-specific characteristic value for each article of an order with one or more order lines, wherein the article-specific characteristic value is selected from the group comprising dimension, weight, volume and / or geometric shape, Determination of a order-specific characteristic value based on the one or more order lines that are processed for an order, and the item-specific characteristic values for each article,

Determination of a load-specific characteristic value of at least one first destination container in which the articles for the named order are to be stored,

Determination of the number of additionally required second destination containers for processing the named order based on the order-specific characteristic value and load-specific characteristic value, if an article can not be stored in the first destination container,

Providing at least one first source container at the picking location for processing at least one first order line to the order,

Providing the first destination bin at the loading site for processing one or more order lines to the order, extracting an article from at least the first source bin, and placing that article in the first destination bin according to the order;

Triggering a control signal after the delivery of an article as the last article for the first destination container, with which a conveyor on the loading station is controlled by the control unit such that the finished first destination container is removed from the loading station and a second destination container is transported to the loading station,

Providing at least the second destination container on the loading site for processing at least one order line for the order,

Remove an article from the first source container and place this article in the second destination container according to the order. The following procedural measures also prove advantageous:

Providing a destination container distribution system with the sorting buffer and a destination container conveyor with a conveyor for transporting empty destination containers, bypassing the sorting buffer to the loading location,

Identifying an empty target container and assignment to a detected order, request and transport of the empty target container to the loading station after the triggering of a control signal after the delivery of an article as the last article for the first target container, with which the conveyor is controlled by the control unit such that the empty destination container is transported to the loading location for processing the at least one order line to the order.

By this method measure, an optimum degree of filling of the target containers is determined from a preliminary calculation. If the picking process is carried out by a picking person, then this has to act only after picking instructions. The order picking process is particularly simple and special specialist knowledge of the picking person is not required. Otherwise, a robot can start picking the items based on the pre-calculation.

The following methodological measures are also advantageous: detection of at least one article-specific characteristic value for each article of an order with one or more order lines, the article-specific characteristic value being selected from the group comprising dimension, weight, volume and / or geometric shape, determination of an order-specific characteristic value based on the one or more order lines being processed for an order, and the article-specific characteristics for each article, Determination of a load-specific characteristic value of at least one first destination container in which the articles for the named order are to be stored,

Triggering a control signal after it has been determined that an article in the first target container can not be stored, with which at least one funding in the sorting buffer is controlled by the control unit such that the not further fillable first target container from the sorting buffer on a target container conveyor for transporting the first Target container is transported, providing at least a first source container on the sampling site for

Processing at least a first order line for the order,

Providing the second destination container at the loading location for processing one or more order lines for the order,

Remove an article at least from the first source container and place this article in the second destination container according to the order.

The following procedural measures also prove advantageous:

Identifying an empty destination container and assigning it to a recorded task Request and transport of the empty target container to the loading point after the triggering of a control signal after it has been determined that an article in the first target container can not be stored, with which the conveyor is controlled by the control unit such that the empty target container to the loading place for processing tion of the at least one order line is transported to the order.

By this method measure, an optimum degree of filling of the target containers is determined from a preliminary calculation. If it is found that a target container in the sorting buffer can not be loaded further, this is transported away directly from the sorting buffer. The loading area is not blocked, which has a positive effect on the picking performance.

The following procedural measures also prove to be advantageous: provision of a target container distribution system with the sorting buffer and a

Target container conveyor with a conveyor for transporting empty target containers either to the sorting buffer or bypassing the sorting buffer to the loading point, evaluation of the order of the source container in the Pufferstreckenab section, which are required for processing order lines to different orders,

Evaluation of the existing in the sorting buffer target container, triggering a control signal after it has been determined that in the Pufferstreckenab section a source container for processing one or more order lines is promoted to a job and in addition to the target containers in the sorting buffer target container must be requested, identifying the empty target container and Assignment to the order,

Transporting the empty target container either to the sorting buffer or to the loading point after the triggering of a control signal with which the conveyor of the control unit is controlled such that the empty target container is transported either to the sorting buffer or to the loading point for processing the at least one order line to the job. After a first execution, the empty target containers are transported directly to the loading place. The empty target containers are only requested when needed and provided at the loading point. In this case, only destination containers are included in the sorting buffer, which already contain an article for an order line. After a second execution, empty target containers are also transported to the sorting buffer. In this case, empty sorting containers and target containers, which already contain an article for an order line, are included in the sorting buffer.

It is also advantageous if the destination container conveyor system has a destination container conveyor system for transporting empty or partially picked destination containers to the loading location and for transporting loaded destination containers from the loading location, the destination container conveyor system for transporting laden destination containers from the loading location and the source container conveyor system for the removal of source containers from the picking station via a conveyor device with a conveyor are connected to each other, and the control unit controls the conveyor to auszuschleusen the target container from Zielbehälter- distribution system on the Quellbehälter- distribution system. This design achieves a space-saving construction of the commuter station.

It can also be provided that the destination container distribution system has a destination container conveyor system for transporting empty or partially picked destination containers to the loading point and for transporting loaded destination containers from the loading station, wherein the destination container conveyor system for transporting empty or partially picked destination containers to the loading point to the Attachment device connects with the loading station and connects the destination container conveyor for removal of loaded target containers from the loading point to the paging device with the loading station. Through this design, a space-saving construction of the picking station is achieved. According to one embodiment of the invention, it can also be provided that the destination container distribution system has a destination container conveying system for transporting empty or partly commissured destination containers to the loading location and for transporting loaded destination containers from the loading location, the destination container conveyor system for transporting empty containers or partially picked target containers to the loading station to the first conveyor or second conveyor of the sorting buffer connects and connects the target container conveyor for transporting laden destination containers from the loading point to the paging device with the loading. Depending on the arrangement of the conveyor for transporting empty or teilkommissionierten target containers they can be transported either to the first conveyor device or the second conveyor. It is thus possible, for example, for a partially picked target container, which was processed in a preceding picking station, to be transported to the first conveying device and thus to a buffer space, provided that a source container assigned to it is already in the buffer section section. Otherwise, a partially picked target container, which was rather processed in a previous order picking station, is transported to the second conveyor and thus to a sorting station, provided that a source container associated therewith is not yet located in the puff section. Also, according to this embodiment, the transport of empty destination containers in the sorting buffer is possible. This use case is when an empty target container is used as a collection container. Such collection containers are mainly used for less extensive orders, in particular for orders with only one order line. In this case, a collection container can contain multiple orders, each with an order line.

According to one embodiment of the invention, the dispensing direction of the first conveyor device and the return direction of the second conveyor device are opposite. As a result, a sorting buffer with maximum functionality can be created in the smallest space together with the third conveyor devices. In addition, the movement paths of the target containers along the first conveyor and the second conveyor and between these conveyors are optimized, so that the sorting times are low and high sorting performance is achieved.

It proves to be an advantage if the sorting buffer has a maximum of 20 sorting places and a maximum of 20 buffer places. The object of the invention is achieved by transporting a first returned merchandiser for processing return warehouse orders after depositing a returned item back to the sorting buffer and temporarily buffering it on a first sorting station until a source container stores a returned item to a second deposit order in a buffer section provided upstream from the loading station, and said first returned merchandise can be moved from the first sorting station to one of the buffer locations and thereafter to the unloading station after the source container for depositing a returned item into a second depository order Buffer line section was transported, and a second return goods container for processing storage back orders after depositing a returned goods to a first deposit order transported back into the sorting buffer and via a second sorting station is moved to one of the buffer locations and then to the picking location, if a source container for storing a returned goods to a second depository order was already transported cut provided in the upstream of the loading point Pufferstreckenab.

Furthermore, the object of the invention is achieved in that the sorting buffer on a first conveyor in a dispensing direction successively arranged buffer locations and on a second conveyor in a return direction successively arranged sorting stations and the sorting points with the buffer stations connecting third conveyor devices, and that the Andienungsvorrich- device with the first unloading station is formed on a fourth conveying device, the first conveying device and the second conveying device being connected to one another via the fourth conveying device in order to request the return containers for processing depository orders from the sorting buffer to the unloading station and to request them from the unloading station to the sorting buffer, and wherein the first conveying device has at least one conveying means for transporting the returned goods and the second conveying device has at least one conveying means for transporting the returned goods, the conveying means for transporting the buffering stations and the sorting stations

Return goods are associated with payers, and a control unit selectively and selectively controls the conveyors so that the returned goods are sorted in the sorting buffer in an order determined depending on the order in which the source containers are provided at the loading location, and that Source container and a Retourwarenb ehälter arrive to an order in about the same time at the loading point and unloading place.

The sort function is taken over by the sort buffer. In this case, a small number of returned goods containers are sorted in comparison to the number of source containers. The sorting buffer is located directly in the vicinity of the picking station. The return goods containers can be transported to the picking station very quickly. Specifically, from the sorting buffer, the sorting function of the returned goods containers, the provision of the returned goods containers in the sorted order, and the transport of the returned goods containers from the sorting buffer and into the sorting buffer are realized. For this purpose, standardized conveyors are used, which work reliably. In the sorting buffer, the return goods containers are preferably transported on a horizontal transport plane, which is formed by the conveying means. In a preferred embodiment, different return goods types are included in the returned goods containers. Thus, multiple return storage orders are also recorded for a returned goods container and a source container is provided for each of these return storage orders. If the source containers contain different article types, returned goods can be stored for different backorder orders in a source container.

The picking station includes a single loading point for a source container and a single picking point for a Retourwarenb ehälter. This may cause erroneous be reduced to a minimum, provided that the picking is carried out manually. Likewise, the picking person hardly needs to move from the place.

In principle, however, more than one loading point for source containers and more than one take-off point for returned goods containers can be provided.

The process steps are also advantageous:

Transporting the at least some returned goods containers from a provisioning station via a returned goods container conveyor to the sorting buffer,

Transferring the at least some returned goods containers to the sorting buffer,

Transporting the returned goods containers from the sorting buffer in the sorted order and consecutively to the picking location.

The returned goods containers are initially transported to the sorting buffer and only after an associated source container is present in the puff section, to the picking location. Another advantage is the procedural measure:

Transport of at least some Retourwarenb ehälter of a provisioning a return goods container conveyor technology, bypassing the sorting buffer to the sampling.

A returned goods container can be transported directly to the picking station if there is an associated source container in the puff section, or if you want to start with the return mode and process the first returned goods container. For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position.

In Fig. 1, a picking system with a warehouse 1, one or more automatically operated picking stations 2, a source container distribution system 3 and a Zielbehälter- distribution system 4 is shown.

The bearing 1 shown by way of example serves primarily to provide a plurality of source containers 5, in which articles (not shown) are contained. The source containers may each contain a single item type. For example, a first source container contains the (storage) item "A", a second source container the (storage) item "B", etc. On the other hand, the source containers 5 can be divided by dividing walls into a plurality of receiving compartments and accommodating different types of items. Bearing) article "A" and in the second receiving compartment a (bearing) article "B" can be added. By segmented source container 5, the number of articles in the warehouse 1 can be increased.

In principle, it is also conceivable that the target containers are divided by dividing walls into a plurality of receiving compartments and receive different orders, wherein in the first receiving compartment a first order with one or more articles and in the second receiving compartment a second order can be recorded with one or more articles. The target containers can also be designed without partitions and accommodate different orders. By segmenting the target container, the sorting buffer described below can be reduced, therefore the number of sorting locations and buffer locations are reduced. Retourware can also be taken up in these source containers 5, with the returned items being item-specifically stored in the source containers 5 or in the receiving compartments.

The invention is not to be understood as limited to containers. Rather, other loading aids, such as trays, boxes and the like. Be used.

The bearing 1 is preferably an automated bearing. The bearing 1 comprises according to the embodiment shown parallel arranged storage shelves 6 and provided between the storage shelves 6 Regalgasse 7. Each storage rack 6 forms in superimposed shelf levels side by side a plurality of storage bins 8, on which the source container 5 are stored. In the example shown, two storage shelves 6 are shown. In the context of the invention, however, more than two storage shelves 6 can be provided, wherein between adjacent storage shelves 6 each a rack aisle 7 is formed.

The source container distribution system 3 is used to transport source containers 5 between the warehouse 1 and the picking station (s) 2. The source container distribution system 3 is preferably an automated source container distribution system. The outsourcing of source containers 5 from the warehouse 1 can be automated and the transport of the source containers 5 from the warehouse 1 to the order-picking station 2 can be automated. The source container distribution system 3 comprises, for example, one or more storage and retrieval devices 9 and a source container conveyor between the warehouse 1 and the order picking 2 to transport source container 5 from the warehouse 1 to the respective order picking 2 and to source container 5 from the order picking 2 to the camp 1 to transport. The source container conveyor can, for example, a first conveyor 10 for transporting source containers 5 to the warehouse 1 and a second conveyor 11 for transporting source containers 5 from the warehouse 1 and a third conveyor 12 for transporting source containers 5 to the order picking station 2 and a fourth conveyor 13 for Removal of source containers 5 from the order picking station 2 and finally a fifth conveyor 14 for transporting source containers 5 between the conveyors 10, 11, 12, 13 have. The fifth conveying device 14 comprises input and / or discharge devices 15, around the source containers 5 between the conveying devices 10 to 14 to transport. The fifth conveyor 14 is, for example, a closed conveyor loop. The input and / or outfeed device 15 is formed for example by a belt converter. On the other hand, the input and / or outfeed device 15 can also be formed by a slide which can be actuated by means of an actuator (not shown).

The source container distribution system 3 may additionally comprise a transfer device 16 for transporting source containers 5 between the storage operator 9 and the source container conveyor.

If single-level rack operating devices are used as storage and retrieval unit 9 in warehouse 1, guideways 17 are arranged in pairs one above the other in horizontal (horizontal) driving planes. The guideways 17 are preferably attached to the adjacent storage shelves 6. The one-level shelving operating units (shuttles), which can be controlled independently of one another by a control unit, can be moved along the aisle 7 and can be moved in front of the storage spaces 8 in the superimposed driving levels.

The storage and retrieval device 9 comprises a loading platform and a transport device 18 (load receiving device). The transport device 18 can manipulate the source containers 5 between the loading platform and the storage location 8, namely to store the source containers 5 in the storage shelves 6 arranged on both sides of the storage operating device 9 or to swap the source containers 5 out of the storage shelves 6 arranged on both sides of the storage operating device 9. It can be provided that each shelf level is assigned at least one storage control unit 9. Thus, a storage and retrieval device 9 via the transport device 18 serves a shelf level.

In detail, the storage and retrieval of source containers 5 by means of the storage and retrieval devices 9, the transfer device 16 and the conveyors 10, 11 in WO

2013/090970 A2.

The transfer device 16 comprises a first buffer device 19a, a first lifting device 20a, a second buffering device 19b and a second lifting device 20b. The buffer device 19a comprises per transport level provision devices for the intermediate buffering of one or more source containers 5 to be stored and the buffer device 19b comprises supply devices for the intermediate buffering of one or more source containers 5 to be stored per driving level. Other variants are also possible, as described in WO 2013/090970 A2.

The lifting devices 20a, 20b are set up in a stationary manner and each comprise a transfer device which can be raised and lowered by means of a lifting drive. Preferably, the transfer devices are each mounted on a vertical mast and each comprise a drivable conveying device.

The source container distribution system 3 may include an optional escape buffer 21 with a conveyor 22. The conveyor 22 is formed for example by a belt converter. The escape buffer 21 is connected to a puff he track section 23. The puff-extending portion 23 is provided upstream of the take-off place. Preferably, the puff extending portion 23 connects to the unloading station and extends along the third conveyor 12. The conveyor 22 is driven by a control unit 26 to at least one in the (conveying) sequence preceding source container 5 from the puff extending portion 23 to the escape buffer 21st auszuschleusen and at least one subsequent in the order source container 5 past the source container 5 in the escape buffer 21 and then the at least one source container 5 from the escape buffer 21 on the puff extending section 23 (see double arrow). The control unit 26 is set up to evaluate the order of the source containers 5, which are required for processing different order lines for at least one order and transported on the puff-extending section 23, and to determine a modified order in which the source containers are to be transported to the take-off location ,

The source container distribution system 3 may also include an optional turning station 24 with which the source containers 5 discharged from the fifth conveyor 14 are rotated from a transverse orientation to a longitudinal orientation. The source container distribution system 3 may also include an optional sixth conveyor with a conveyor 25. The conveyor 25 is formed for example by a belt converter. The sixth conveyor is connected to the Pufferstreckenab section 23. The conveyor 25 is driven by the control unit 26 based on a (to be described later) control signal to promote a first source container 5 after the removal of an article from the sampling place on the Pufferstreckenab section 23. However, the control signal can also be triggered if the source container 5 is to be transported away from the removal location 33, although no articles or no further articles have been stored in the destination container 27, as will be described later. The control unit 26 is set up to process the control signal after the last removal of an article from the source container 5 or the last delivery of an article into the destination container 27.

The destination container distribution system 4 is used to transport finished destination containers 27 between the picking station (s) 2 and a goods issue, as indicated by the arrow 28, or the transport of partially picked destination containers 27 between a first picking station 2 and a second picking station 2. The destination container distribution system 4 further serves to transport empty destination containers 27 or partially picked destination containers 27 to the picking station (s) 2. The destination container distribution system 4 is preferably an automated destination container distribution system. It can be done automated transport of destination target container 27.

The destination container distribution system 4 comprises a destination container conveyor system. The Zielbehälter- conveyor technology, for example, a first conveyor 29 for transporting empty target containers 27 and / or partially picked target containers 27 to the / the respective picking station (s) 2 and a second conveyor 30 for transporting partially picked target containers 27 and finished target containers 27 of the / include the picking station (s) 2 concerned. The first conveying device 29 for transporting empty destination containers 27 and / or partially picked destination containers 27 connects to a delivery device with the loading point for a destination container 27. The second conveyor 30 for the removal of partially picked destination containers 27 or finished destination containers 27 connects either to the delivery device with the loading point for a target container 27 or to the sorting buffer 36 at. If the second conveyor device 30 connects to the sorting buffer 36, the destination containers 27 in the sorting buffer 36 are transferred over the second conveying device 40 is transported to the second conveying device 40 of the target container conveying system and discharged there via the conveying means 31 from the sorting buffer 36 to the target container conveying system. Optionally, the target container conveyor with its first conveyor 29 for transporting empty target containers 27 and / or partially picked target containers 27 to the respective picking station (s) 2 to the sorting buffer 36 connect (as exemplified in Fig. 1 in dotted lines) so that empty destination containers 27 and / or partially picked destination containers 27 are initially transported into the sorting buffer 36 and, if appropriate, sorted to the picking station (s) 2 in question.

The first conveying device 29 can connect either to the first conveying device 37 of the sorting buffer to be described in more detail or to the second conveying device 40 of the sorting buffer, which will be described in more detail later. In contrast to the illustration in FIG. 1, the first conveying device 29 can also be connected to the fifth conveying device 14 in order to transport empty target containers 27 and / or partially picked target containers 27. The empty destination containers 27 and / or partially picked destination containers 27 are transferred to a buffer space 39-5 and then transported to the loading location 35 or to a sorting location 42-1. A partially picked destination container 27 can also be transported from a buffer location 39-5 and to a sorting location 42-1, provided that the source container assigned to the partially picked target container 27 has not yet been transported to the buffer section 23.

However, it is also possible for the destination container conveyor system to comprise a first conveyor device 29 with separate transport of empty destination containers 27 and partially picked destination containers 27, one of the first conveyor device 29 for transporting empty destination containers 27 to the delivery device of the commissioning station 2 and connect the other of the first conveyor device 29 to the delivery of partially picked target containers 27 to the sorting buffer. The conveying device 13 for transporting source containers 5 from the unloading station and the conveying device 30 for transporting loaded destination containers 27 from the loading station are connected to one another via a third conveying device with a conveying means 31. The conveyor 31 is formed for example by a belt converter. The conveyor 31 is controlled by the control unit 26 in order to discharge the loaded destination containers 27 from the destination container conveyor to the source container conveyor system. According to the embodiment shown, for space-saving reasons, a single conveying device 13 is used for transporting loaded destination containers 27 from the loading station and for transporting source containers 5 from the unloading station. It would also be conceivable to use two separate conveying devices 13, 30.

The picking station (s) 2 is / are connected to the source container conveyor of the source container distribution system and the destination container conveyor of the destination container distribution system.

The order-picking station 2 comprises a delivery device 32 for providing a source container 5 at a single take-off location 33 (removal position) and a delivery device 34 for providing a destination container 27 at a single loading location 35 (loading position) and a sorting buffer 36. The sorting buffer 36 is an automatically operated sorting buffer , The transport of the target container 27 in the sorting buffer 36 (in particular between the buffer and sorting stations 39, 42) and the sorting of the target container 27 by the sorting buffer 36 is automated. In particular, the transport of the target container 27 from the sorting buffer 36 to the loading point 35 and the return transport of the target container 27 from the loading point 35 into the sorting buffer 36 is automated, therefore, the provision of the destination container 27 is automated at the loading point 35. Likewise, the transport of the source container 5 to the take-off point 33 and the transport of the source container 5 from the take-off point 33 can be automated, therefore, the provision of the source container 5 takes place at the removal point 33 automated.

The sorting buffer 36 comprises on a first conveyor 37 in a discharge direction (arrow from left to right) successively arranged buffer locations 39 and on a second conveyor 40 in a return direction (arrow from right to left) successively arranged sorting stations 42 and the buffer sites 39 with the sorting 42 connecting third conveying devices 43. According to a preferred embodiment, the first conveying device 37 and second conveying device are arranged in parallel, while the third conveying devices 43 are perpendicular to the first conveying device 37 / second conveying device 40 are arranged. The discharge direction of the requested target containers 27 on the first conveyor 37 and the return direction of the returned target containers 27 on the second conveyor 40 extend in the opposite direction. The delivery device 34 for the target containers 27 is formed on a fourth conveyor 48. The first conveying device 37 and the second conveying device are connected to one another via the fourth conveying device 48 in order to request the target containers 27 for processing different order lines for at least one order from the sorting buffer 36 to the loading station 35 and to request them from the loading station 35 to the sorting buffer 36. The first conveying device 37 and the second conveying device 40 each have conveying means 44, 45. The target containers 27 are transported to the processing of orders on the first conveyor 37 by means of the conveying means 44 in the discharge direction and sorted to the loading position 35. The conveyor 44 forms a horizontal conveyor plane. On the other hand, after a processing of orders and which still require articles for orders, target containers 27 can be transported on the second conveyor 40 by means of the conveying means 45 in the return direction from the loading station 35 to the sorting stations 42. The conveying means 45 forms a horizontal conveying plane.

The conveying means 44, 45 each have, for example, on a frame rotatable mounted conveyor rollers and each form a roller conveyor. At least one conveying means 44 for transporting the destination containers 27 in the discharge direction and the sorting stations 42 are assigned to the buffer spaces 39 at least one conveying means 45 for transporting the destination containers 27 in the return direction. The conveyor 44 is driven and coupled to a first drive motor. The conveyor 45 is driven and coupled to a second drive motor. According to the embodiment shown, each buffer space 39 comprises a conveying means 44 with a plurality of conveying rollers, of which at least one conveying roller is driven and coupled to a drive motor. In addition, each sorting station 42 comprises a conveyor 45 with a plurality of conveyor rollers, of which at least one conveyor roller is driven and coupled to a drive motor. The drive motors are connected to the control unit 26, and the conveying means 44, 45 can be controlled separately by the control unit 26. The third conveying devices 43 connect the opposing buffer locations 39 and sorting stations 42 in order to deliver the destination containers 27 from the control unit 26 to the buffer locations 39 in a time-controlled manner from the sorting locations 42 so that the destination containers 27 already leave the sorting buffer 36 in a sorted order and This sorted order the loading point 35 are supplied sequentially. The third conveying devices 43 each have conveying means 46, 47. The target containers 27 are transported for processing orders on the third conveyor 43 by means of the conveying means 46, 47 from the sorting stations 42 to the buffer stations 39. The conveying means 46, 47 forms a horizontal conveying plane. The conveying means 46, 47 for each third conveying device 43 is driven and coupled with a third drive motor.

As can be seen from FIGS. 1 and 2, some of the buffer locations 39 and sorting sites 42 can each be assigned a common conveying means 46. Otherwise, some of the buffer locations 39 and sorting sites 42 per buffer space 39 can be allocated a conveying means 47 and for each sorting space 42 a conveying means 47 can be assigned.

The conveying means 46, 47 are each formed by a belt converter, for example. Belt converters of this type (and this also applies to the belt converters mentioned elsewhere) have conveyor belts coupled to a drive motor, which are mounted on a lifting mechanism and form the conveying plane. The conveyor belt can via the hoist between a raised conveyor position in which a target container 27 is lifted from a sorting station 42 and conveyed on the conveyor belt to a buffer space 39, and a lowered rest position in which the conveyor belt below the conveying plane of the conveyor 44, 45 lowered and a destination container 27 is transported by the conveyor 45 to a sorting station or destination container 27 from the conveyor 45 from a first sorting station 39 to a second sorting station.

On the other hand, the conveying means 46, 47 may each also be formed by a slide which can be actuated by means of an actuator (not shown), in which case the buffer spaces 39 and sorting stations 42 are connected via a "passive" sliding surface.

The conveyor 47 on the sorting station 42-4 and the conveyor 47 on the buffer station 39-2 can be operated bidirectionally. Optionally, the conveyor 47 on the sorting station 42-5 and the conveyor 47 are bidirectionally operated on the buffer space 39-2. However, the conveying means 46 for the sorting stations 42-1 to 42-3 and buffer stations 39-3 to 39-5 can also be operated bidirectionally. The conveying means 44, 45, 46, 47 are controlled by the control unit 26 such that the

Target containers 27 are sorted in the sorting buffer 36 in an order determined depending on the order in which the source containers 5 are provided at the picking place, and that a source container 5 and a destination container 27 arrive at an order at about the same time at the picking place and loading place ,

As can also be seen in the figure, a conversion direction (arrow from top to bottom) of the target container 27 returned to the sorting buffer 36 from the loading station 35 runs essentially perpendicular to the discharge direction and return direction. The drive motors / actuators are connected to the control unit 26, and the conveying means 46, 47 can be controlled separately by the control unit 26.

In an advantageous embodiment, the sorting buffer 36 comprises a maximum of 20 buffer locations and a maximum of 20 sorting locations. The number of buffer locations and sorting locations can be determined depending on the product assortment and / or batch sizes and / or container type. The number of buffer locations and sorting locations will tend to be higher if there is a large assortment width but a small lot size. In contrast, the sorting buffer 36 may have a minimum number of buffer locations and sorting locations as the range of products decreases and higher batch sizes exist. The sorting buffer 36 may also have only two buffer locations and two sorting locations for simple applications.

The delivery device 32 shown for providing a source container 3 at a single take-off location 33 (removal position) comprises an arc-shaped deflection conveyor technology, which the third conveying device 12 for transporting source containers 5 to the order picking station 2 and the fourth conveying device 13 for transporting source containers 5 from the order picking station 2 connects with each other. The Umlenkfördertechnik has funding 49. The source containers 5 are transported for processing orders by means of the third conveyor 12 to the Andienungsvorrichtung 32 and on the Delivery device 32 transported by means of the conveyor 49 to the unloading station 33. Preferably, the source container 5 is temporarily stopped at the removal location 33 in order to carry out the picking process by a picking person (as shown) or a robot. The conveyor 49 is driven and coupled with a drive motor. The conveyor 49 has, for example, on a frame rotatable mounted conveyor rollers.

The delivery device 34 shown for providing a destination container 27 on a single loading location 35 (loading position) comprises an arc-shaped deflection conveying technology which connects the first conveying device 37 and the second conveying device 40 to one another. The Umlenkfördertechnik has funding 50. The target containers 27 are transported for processing orders by means of the first conveyor 37 to the Andienungsvorrichtung 34 and further transported on the Andienungsvorrichtung 34 by means of the conveyor 50 to the loading station 35. Preferably, the target container 27 is temporarily stopped at the loading location 35 in order to carry out the picking process by a picking person (as shown) or a robot. The conveyor 50 is driven and coupled to a drive motor. The conveyor 50 has, for example, on a frame rotatable mounted conveyor rollers. In addition, the order picking station 2 may comprise an input and / or output system 51, which is connected to the control unit 26.

If picking by a picking person, so an input and output system 51 is provided with an acknowledgment button and a display. The display comprises a display panel by means of which a numeric or alphanumeric (visual) output of

Picking instructions can be done. For example, the order picking person is signaled on the display as to which number of articles should be taken from the source container 5 and stored in the destination container 27. After the last removal of an article from the source container 5 or after the last delivery of an article in the target container 27, a control signal is triggered, if the order picker actuates the acknowledgment button on input and / or output system 51. However, it is also possible to trigger a control signal by actuating the acknowledgment key, provided that the picking person has determined that no article or no other articles can be stored in the target container 27 / can. However, the control signal can also be triggered in other ways, for example by voice input, gestures (eg hand movements) and the like. If picking is performed by a robot, then an input system 51 with a camera system or a suitable other sensor is provided, by means of which, for example, a loading state can be determined in the target container 27. The control unit 26 determines based on the loading state which number of items to be removed from the source container 5 and stored in the target container 27. After the last removal of an article from the source container 5 or after the last dispensing of an article into the destination container 27, a control signal is triggered if the control unit 26 has received an acknowledgment signal, for example from the camera system. However, it is also possible for a control signal to be triggered by the camera system, if it has been determined by the control unit 26 that no article or no further articles can be stored in the target container 27.

As entered in FIG. 1, an order destination point 52 is provided along the transport path between the at least one storage and retrieval device 9 and the take-off location 33, on which the sequence of the source containers 5 is determined. The buffer section 23 preferably extends between the order designation point 52 and the extraction site 33. Thereafter, the order of the source containers 5 is not changed. Only for technical reasons, the order of at least some source container 5 can be modified, as will be described below. The sequence determination point 52 is preferably provided on the infeed and / or outfeed device 15, at which the source containers 5 are transported from the fifth conveying device 14 to the third conveying device 12. The detection of the order of the source container 5 is carried out by the control unit 26, known per se tracking systems (tracking system) are used, which can determine the location of each source container 5 along the transport path. For this purpose, it is necessary for the source containers 5 to be identified and detected by the control unit 26 before they are stored in the warehouse 1. The source containers 5 are each provided with a distinctive (unique) identification code, for example an identification number. In addition, the transport of the source container 5 from the fifth conveying device 14 to the third conveying device 12 be monitored by a sensor (not shown) at the input and / or outfeed device 15. After the location of each source container 5 is known from the tracking and the sensor monitors the transport of the source container 5 from the fifth conveyor 14 to the third conveyor 12, the control unit 26, the order in which the source container 5 extend in the puff section 23rd be transported on the third conveyor 12, be reliably detected.

In the jointly described FIGS. 3a to 3j, a method for picking articles at a picking station 2 is described, at which orders are processed. The conveying means 44, 45, 49, 50 were not included in these figures for reasons of clarity. An order can also be processed in partial orders at a single picking station 2. Otherwise, the orders or partial orders of the orders can also be processed at several order-picking stations 2. In this case, a destination container 27 is initially fed to a first picking station 2 and at least one article is picked. After that, the target container 27 is fed to a second picking station 2 and at least one article is picked. In other words, the order can not be processed completely at a single picking station 2 and the destination container 27 is transported to the second picking station 2 after the partial picking in the first picking station 2 via the fifth conveying device 14 (FIG.

For the sake of simplicity, "orders" are referred to below: An order can also be understood as a picking order A customer order comprises at least one order The orders are available as data records The orders are electronically recorded on a computer (not shown) and the control unit 26 (FIGURE 1) Each order includes one or more order lines

Order lines, so different articles are needed. Each order line has at least information about a quantity of an ordered article and about an article type. In e-commerce, the lot sizes are small, so that there is a relatively high number of different orders with only a few order lines. A first job may include a single job line, for example, 1 book. A second order may include a first order line, for example 2 pieces of DVD and a second order line, for example 7 pieces of CD's. A third order may be a first order line, for example 20 pieces of ballpoint, a second order line, for example 12 pieces of notebooks, one third order line, for example 1 piece of copy paper, a fourth order line, for example 3 pieces of staples, etc.

For the first processing of (new) orders empty destination containers 27 are fed via the conveyor device 29. The empty destination containers 27 are identified and an empty destination container 27 is linked to a recorded order in terms of data.

The transport of the identified and empty destination container 27 to the loading station 35 takes place after the triggering of a control signal described above by manual actuation of an acknowledgment button on the input and / or output system 51 or by detecting an acknowledgment signal, for example a camera system. With this control signal, the conveyor device 29 is controlled by the control unit 26 such that the empty target container 27 (bypassing the sorting buffer) is transported to the loading station 35 for processing the at least one order line to the job.

In the sorting buffer 36 target containers 27 are temporarily buffered, which require articles for more than one order line and already contain a first order line. Therefore, in each case at least one article was stored in the destination containers 27. However, some destination containers 27 may also be empty, which are fed via the conveyor system 29 adjoining the sorting buffer 36.

If, for example, the order comprises a first order line (2 pieces of DVD) and a second order line (7 pieces of CD) and if a (first) source container 5 provided on the take-off location 33 contains the articles for the first order line, the destination container 27 will be after picking the articles for the first order line for the time being transported to the sorting buffer 36. If a (second) source container 5 with the article for the second order line is provided on the picking location 33, the destination container 27 is repeatedly provided on the (single) loading place 35 and the article is commissions for the second order line. This process is carried out at the commissioning station 2 for a number of orders. The source containers 5 are stored in a disorderly (chaotic) order from the warehouse 1 and conveyed in a disorderly (chaotic) order to the take-off place 33. The sequence in which the source containers 5 are conveyed to the removal location 33 may differ from the order in which the source containers 5 are unloaded from the warehouse 1. Preferably, the source containers 5 each store a single item type. One speaks of so-called "article-type" source containers 5.

Usually, at station 2, a number of jobs are to be processed and some jobs are included that include more than one job line. As a result, the target containers 27 must be provided several times at the (single) loading place 35 and in an order determined depending on the order in which the source containers 5 are provided on the take-off place 33, as described above. 3a shows a possible operating state at the order-picking station 2. Each of the order lines (position 1, position 2, etc.) has at least information about the order lines "AI to A6" assigned to this picking station 2.

As can be seen, in the sorting buffer 36 on the sorting locations 42-1 to 42-3 and on the buffer space 39-2 destination containers 27 are located at different orders, for example a destination container "T3" for an order "A3", a destination container "T4" to an order "A4", a destination container "T5" to an order "A5" and a destination container "T6" to an order "A6". In addition, on the paging device 34 target containers 27 for different orders, for example, a target container "T2" to a job "A2" and a target container "Tl" to a job "AI". The order "AI" is currently being processed.

As not shown in detail, an empty target container 27 for the order "AI" is previously supplied to the order picking station 2 via the conveying device 29. The empty target container 27 is identified and linked to the data "AI". The target container 27 now corresponds to the target container "Tl." Meanwhile, the source container "Sl. L" from the Pufferstreckenab section 23 is transported to the removal point 33. Is the source container "Sl. l "provided on the picking 33 and the target container" Tl "on the loading point 35, a first order line can be edited, therefore, 2 pieces of red pens from the source container" Sl. l "and stored in the target container" Tl ". The target container "Tl" is then transported from the loading station 35 back into the sorting buffer 36 and to a sorting station 42-4 determined by the control unit 26, since a second order line (item 2) is yet to be processed.

For further processing of the orders "AI to A6", the source containers 5 are removed from the warehouse 1 and transported via the source container conveyor to the order-picking station 2. Each source container 5 contains an article for processing an order line an order. This means that the source container "S1.2" for the second order line (position 2) the article "pen yellow", the source container "S2.3" for the third order line (position 3) the article "care product", the source container " S3.2 "for the second order line (item 2) the article" T-shirt green ", the source container" S1.3 "for the third order line (item 3) the article" pen green ", the source container" S2. 4 "for the fourth order line (position 4) the item" cleaning brush "and the source container" S3.3 "for the third order line (position 3) store the item" T-shirt black ". The first place in the terminology "Sx.y" designates the order and the second place designates the order line As can be seen, some of the source containers "S1.2 to S3.3" required for the orders "AI to A6" are already located extending in a puff section 23 of the source container distribution system, in particular the source container conveyor.

Although the source containers "S1.2 to S3.3" are supplied to the picking place 33 in a disordered order, this order is detected at the order designation point 52 (Figure 1). The destination containers "T1 to T3" are placed in and through the sorting buffer 36 sorted in an order determined by the order of the source containers "S1.2 to S3.3." In Fig. 3a, the source container "S1.2" for the second order line (position 2) is located on the take-off location 33 and the destination containers The second order line (item 2) comprises 4 pieces of yellow pens which are taken from the source container "S1.2" and deposited in the destination container "T1." After the last (manual or automatic) removal of a Article from the source container "S1.2" or last delivery of an article in the target container "Tl a control signal is triggered. With this control signal, at least the buffer section 23 and the conveying means 49 on the pressing device 32 and the conveying means 50 on the delivery device 34 and the conveying means 45 on the conveying device 40 are controlled by the control unit 26 such that the source container "S1.2 "transported from the picking 33, the source container" S2.3 "transported to the picking place 33, the previously processed target container" Tl "transported from the loading point 35 and the still to be processed target container" T2 "are transported to the loading station 35. As can be seen in FIG. 3b, the previously processed target container "T1" is transported from the loading location 35 back into the sorting buffer 36 and to a sorting station 42-4 determined by the control unit 26, since a third order line (item 3) is yet to be processed The source container "S1.2" is transported on the source container conveyor system from the removal station 33 and stored back into the warehouse 1. If the source container "S2.3" provided on the unloading station 33 and the target container "T2" on the loading point 35, the third order line (position 3) can be edited, therefore 1 piece of care product from the source container "S2.3" removed and Target container "T2" filed. After the (manual or automatic) removal of the single article from the source container "S2.3" or last delivery of the single article in the destination container "T2", a control signal is triggered. With this control signal, at least the puff he distance section 23 and the conveyor 49 on the Andienungsvorrichtung 32 and the conveyor means 50 on the Andienungsvorrichtung 34 and the conveyor means 45 of the conveyor 40 by the control unit 26 is controlled such that the source container "S2.3" from the sampling 33 transported away, the source container "S3.2" transported to the removal point 33, the previously processed target container "T2" transported from the loading point 35, the still to be processed target container "T3" are transported to the loading point 35. The source container "S2.3" is transported away via the source container conveyor system (FIG. 3d). The previously processed target container "T2" is returned from the loading location 35 back to the sorting buffer 36 and to a sorting location 42- determined by the control unit 26. 4, since a fourth order line (position 4) needs to be processed (Fig. 3d). In the meantime, the source container "S2.5" for the fifth order line (item 5) with the article "detergent" in the puff section 23 was transported. As can be seen in FIG. 3c, the target container "T1" can be moved directly from the sorting location 42-4 to one of the buffer locations 39-2 determined by the control unit 26 and then to the delivery device 34 after the source container "S1.3" has already been moved. with an article for the third order line (position 3) in the puff section 23 was transported. The transport of the destination container "T1" from one of the sorting locations 42-4 to one of the buffer locations 39-2 takes place by means of the conveying means 46, 47 of one of the third conveying devices 43, for example the conveying means 47 of the sorting station 42-4 and buffer space 39-2 In this case, conveying means 46, 47 are activated by the control unit 26. The target container "T1" is moved past the target containers "T4 to T6" temporarily buffered in the sorting buffer 36 on the sorting sites 42-1 to 42-3. Thus, a sorting process is performed by the sorting buffer 36 via the sorting locations 42-1 to 42-5. As can be seen in FIG. 3d, the destination container "T2" was transported from the loading location 35 back into the sorting buffer 36 and to a sorting location 42-4 determined by the control unit 26, since a fourth order line (position 4) still has to be processed "T1" was transported from the sorting buffer 36 from one of the buffer locations 39-2 to the delivery device 34. The target container "Tl" is doing after the (manual or automatic) see removal of the article from the source container "S2.3" and after the still to be processed target container "T3" on the loading point 35 and the previously processed target container "T2" on one of the sorting stations 42-4 determined by the control unit 26 have been transported from the buffer space 39-2 to the delivery device 34. For this purpose, after the (manual or automatic) removal of the article from the source container "S2.3" or last delivery of the article in the target container "T2" a control signal is triggered and the conveyor 44 of the first conveyor 37 and the conveyor 50 of the Andienungsvorrichtung 34th is controlled by the control unit 26 in such a way that the target container "T1" is transported from the buffer space 39-2 to the loading location 35. As shown, the source container "S3.2" is located for the second order line (position 2 ) on the picking station 33 and the target container "T3" on the loading site 35. The second order line (item 2) includes 1 piece of green T-shirt, which is taken from the source container "S3.2" and stored in the destination container "T3". After the (manual or automatic) removal of the article from the source container

A control signal is triggered with this control signal, at least the puff extension section 23 and the conveyor 49 on the passer device 32 and the conveyor 50 on the passer device 34 and the The conveying means 45 of the conveying device 40 are controlled by the control unit 26 in such a manner that the source container "S3.2" is removed from the unloading station 33, the source container "S1.3" is transported to the unloading station 33, the previously processed target container "T3" is removed from the loading station 35 , the target container "T1" to be processed is transported to the loading site 35. The source container "S3.2" becomes transported away via the source container conveyor (Fig. 3e). The previously processed target container "T2" is transported from the loading station 35 back into the sorting buffer 36 and to a sorting station 42-4 determined by the control unit 26, since a fourth order line (item 4) is still to be processed .2 "for the second order line (position 2) with the article" sunglasses "in the buffer line section 23 transported.

As can be seen in FIG. 3e, the destination container "T5" can be transported from the sorting location to one of the buffer locations39-4 determined by the control unit 26, after the source container "S5.2" already has an article for the second order line (position 2). has been transported into the buffer section 23. However, the destination container "T5" can not yet be moved to the loading location 35 or the delivery device 34, since this destination container "T5" still has to line up the destination container "T2." The transport of the destination container "T2" from one of the sorting locations 42-40. 4 to one of the buffer spaces 39-2 by means of the conveyor 46, 47 of the third conveyor devices 43, for example, the conveyor means 47 of the sorting station 42-4 and buffer space 39-2. The transport of the destination container "T5" from one of the sorting locations 42-2 to one of the buffer locations 39-4 takes place by means of the conveying means 46, 47 of one of the third conveying devices 43, for example the conveying means 46 for the sorting station 42-2 and buffer space 39-4. The conveying means 46 and the third conveying devices 43 are actuated independently of one another by the control unit 26. Accordingly, the target containers "T2 and T5" can be parallel between the sorting places 42-2, 42-4 and the buffer places 39-4, 39 -2 are transported. The destination container "T5" may have been transported from the sorting location 42-2 to the buffer space 39-4 before the destination container "T2". In principle, however, the destination container "T5" could also be transported from the sorting location 42-2 to the buffer space 39-4 only after the destination container "T2". The destination container "T2" can be moved past the destination container "T5" and / or sorting locations 42-1, 42-2 temporarily buffered destination containers "T4 to T6" located in the sorting buffer 36 on the buffer space 39-4 the buffer locations 39-1 to 39-5 and / or sorting stations 42-1 to 42-5 performed a sorting process.

After the target container "T5" has been transported from the sorting station 42-2 to the buffering station 39-4, the destination container "T4" can be transported from a sorting station 42-3 in the return direction downstream to a sorting station 42-2. The transport of the target container "T4" from the sorting place 42-3 to the sorting place 42-2 takes place by means of the conveying means 45 of the second conveying device 40 or by means of the conveying means 45 of the sorting places 42-2, 42-3. The / the conveyor 46 is / are controlled by the control unit 26. The destination container "T3", on the other hand, is not transported from the sorting location 42-4 to the sorting location 42-3 since this must be transported directly to the loading position 35.

As can also be seen, the previously processed destination container "T3" is transported from the loading location 35 back into the sorting buffer 36 and to a sorting station 42-4 determined by the control unit 26, since a third order line (position 3) still has to be processed Of course, it is also possible for the destination container "T3" to be transported via the sorting station 42-4 to a sorting station 42-3 determined by the control unit 26.

As can be seen in Fig. 3f, the target container "T2" was transported from the buffer space to the delivery device 34 by means of the conveyor 44 of the first conveyor 37 and the conveyor 50 of the delivery device 34. The destination container "T5" was conveyed by means of the conveyor 44 of Figs transported first conveyor 37 to the buffer space 39-4. On the other hand, the source container "S1.3" for the third order line (position 3) on the take-off point 33 and the destination container "T1" on the loading point 35 are to process the third order line (position 3). Take 1 piece of green pencil from the source container "S1.3" and place it in the target container "T1". After the (manual or automatic) removal of the single article from the source container "S1.3" or the last delivery of an article into the destination container "T1", a control signal is triggered With this control signal, at least the puff section 23 and the conveyor 49 are moved on the delivery device 32 and the conveying means 50 on the delivery device 34 and the conveying means 45 of the conveying device 40 are controlled by the control unit 26 such that the

Source container "S1.3" transported from the removal point 33, the source container "S2.4" transported to the removal point 33, the previously processed target container "Tl" transported from the loading point 35, the still to be processed target container "T2" transported to the loading point 35 become. The source container "S1.3" is transported away via the source container conveyor system and the target container "Tl", which has already been picked for this order, is transported to the destination container conveyor system. The transport of the target container "Tl" from the loading point 35 to the destination container conveyor takes place via the conveyor 45 of the second conveyor 40, the conveyor 47 at the sorting station 42-4 and the conveyor 31 of the conveyor 30. Preferably, the source container conveyor is used as a target container conveyor and the target container "Tl" before or after the source container "S1.3" discharged from the conveyor 30 to the conveyor 13, as entered in Fig. 3g , The target container "Tl" is transported to the goods issue 28.

As can be seen in Fig. 3g, the target container "T5" was transported from the buffer space 39-3 to the buffer space 39-2. The transport of the target container "T5" takes place by means of the conveying means 44 of the first conveying device 37 and the conveying means 44, respectively Buffer places 39- 4, 39-3. The destination container "T4" can be transported from the sorting location 42-2 to one of the buffer locations 39-4 determined by the control unit 26, after the source container "S4.2" with an article for the second order line (position 2) in FIG the buffer section 23 has been transported. However, the target container "T4" can not yet be moved to the loading place 35 because this target container "T4" is preceded by the destination container "T5." The transport of the destination container "T4" from one of the sorting locations 42-2 to one of the buffer locations 39-4 takes place by means of the conveying means 46 of one of the third conveying devices 43. Also, the target container "T5" can not yet be moved to the loading point 35, since this destination container "T5" is to be preceded by the target container "T2".

The source container "S2.4" for the fourth order line (position 4) is at the take-off location 33 and the destination container "T2" is provided at the loading location 35 to process the fourth order line (position 4). Remove 1 piece cleaning brush from the source container "S2.4" and place it in the destination container "T2". After the (manual or automatic) removal of the article from the source container "S2.4" or last delivery of an article in the destination container "T2", a control signal is triggered. With this control signal, at least the buffer section 23 and the conveying means 49 on the delivery device 32 and the conveying means 50 on the delivery device 34 and the conveying means 45 of the conveying device 40 are controlled by the control unit 26 such that the source container "S2.4" transported away from the take-off point 33, the source container "S3.3" transported to the removal point 33, the previously processed target container "T2" transported from the loading point 35, the still to be processed target container "T3" are transported to the loading station 35. The source container "S2.4" is transported away via the source container conveyor system (FIG. 3h). The previously processed target container "T2" is returned from the loading location 35 into the sorting buffer 36 and transported to a sorting station 42-4 determined by the control unit 26, since a fifth order line (position 5) still has to be processed.

As can be seen in FIG. 3h, the source container "S3.3" for the third order line (position 3) is located on the removal location 33 and the destination container "T3" is located on the loading location 35 in order to process the third order line (position 3). In the meantime, the source container "S6.2" for the second order line (item 2) has been transported to the puff-extending portion 23 with the article "shoes black". Thus, the destination bin "T6" may be transported from the sorting site 42-1 to one of the buffer sites 39-5 designated by the controller 26. The destination bin "T4" has been transported from the buffer site 39-4 to the buffer site 39-3. The transport of the target container "T4" takes place by means of the conveying means 44 of the first conveying device 37 and the conveying means 44 of the buffer stations 39-4, 39-3.

As shown in FIG. 3i, the target container "T2" can be moved directly via the sorting location 42-5 to one of the buffer locations 39-1 determined by the control unit 26 and then to the service device 34 or to the loading location 35, respectively already the source container "S2.5" with an article for the fifth order line (position 5) in the buffer stretch section 23 was transported. Target container "T6" was transported from buffer space 39-5 to buffer space 39-4.

Finally, FIG. 3j shows the target container "T2" on the loading place 35 and the source container "S2.5" on the take-off place 33 in order to process the fifth order line (position 5). 1 piece of dishwashing liquid is taken from the source container "S2.5" and deposited in the target container "T2".

After the (manual or automatic) removal of the single article from the source container "S2.5" or last delivery of an article in the destination container "T2", a control signal is triggered. With this control signal, at least the puff-extending section 23 and the conveying means 49 on the delivery device 32 and the conveying means 50 on the control device 34 and the conveying means 45 of the conveying device 40 are controlled by the control unit 26 such that the source container "S2.5" from Removal point 33 transported away, the source container "S5.2" transported to the picking place 33, the previously processed Target container "T2" transported from the loading station 35, the still to be processed target container "T5" are transported to the loading station 35. The source container "S2.5" is then transported away via the source container conveyor system and the destination container "T2", which has already been picked for this order, is subsequently transported to the destination container conveyor system. The transport of the target container "T2" from the loading point 35 on the

Target container conveyor technology takes place via the conveying means 45 of the second conveying device 40, the conveying means 47 at the sorting station 42-4 and the conveying means 31 of the conveyor 30. The target container "T2" is transported to the goods outlet 28. Thereafter the orders "A5, A4, A6 "edited one after the other. The ready-picked destination containers "T5, T4" are in turn transported to the destination container conveyor system.On the order "A6" further order lines are to be processed and this destination container "T6" is moved to the second order line after the articles have been deposited (position 2 ) transported from the loading station 35 back into the sorting buffer 36 and to a certain sorting by the control unit 26, since a third / fourth order line (position 3, 4) is to be processed.

In order to be able to carry out a continuous processing of further orders "A7..An", empty destination containers 27 are fed via the conveying device 29 to the picking station 2, as exemplified in FIG. A7 "linked. The destination container 27 now corresponds to the destination container "T7." Meanwhile, the source container "S7.1" is also transported from the buffer section 23 to the removal location 33. Target container "T7" is lined up with target containers "T4, T6". If the source container "S7.1" is provided on the picking location 33 and the destination container "T7" is provided on the loading location 35, a first order line can be processed. The target container "T7" is then transported from the loading point 35 back into the sorting buffer 36 and to a sorting station determined by the control unit 26, provided that a second order line is still to be processed .. If the order "A7" comprises only a single order line, the destination container becomes The destination container "T7" is transported directly to the destination container conveyor system. It should be pointed out at this point that a destination container "Tl ... T6" can be transported from the loading location 35 to the sorting location 42-5 or another sorting location 42-4 to 42-1, depending on which of the sorting locations 42-1 Basically, the control unit 26 determines the sorting location 42-5 which is unoccupied and as close as possible to the loading location 35. This achieves short changeover times for the provision of the destination containers "T1 ... T6" at the loading location 35.

On the basis of this embodiment, it will be seen that a first target container "Tl ... T6" for processing different order lines to at least one order "AI ... A6" after depositing an article to a first order line transported back into the sorting buffer 36 and is temporarily buffered on a first sorting station at least until a source container "S1.2 ... S6.2" with an article to a second order line in a provided upstream of the take-off point 33 Puff section 23 ababschnitts is promoted. Tl ... T6 "can be moved from the first sorting location to one of the buffer locations and then to / on the loading location 35 after the source container" S1.2 ... S6.2 "with an article to a second order line in the buffer path section In this case, according to a first procedure, the named target container "Tl ... T6" immediately after this on the Buffer space 39 is transported to the loading station 35 (see, for example, Fig. 3b to 3d). According to a second procedure, the target container "T1 ... T6" in the order of destination containers "T1 ... T6" on the buffer locations 39 is preceded by another target container "T1 ... T6" and said target container "T1 .. T6". T6 "is moved to the loading station 35 only after the preceding target container" T1 ... T6 "has been moved (see, for example, Figures 3e to 3j). In the operation of the sorting buffer 36, both methods usually occur.

On the other hand, it can also be seen from this embodiment that a second target container "Tl ... T6" for processing different order lines to at least one order "AI ... A6" after placing an article to a first order line back into the sorting buffer 36th transported and moved via a second sorting on one of the buffer locations and then to / on the loading point 35, if a source container "S1.2 ... S6.2" with an article to a second order line already in an upstream of the take-off 33rd provided Pufferstreckenab section 23 was transported. The target containers "Tl ... T6" are transported from the sorting buffer 36 in the sorted sequence and consecutively to the loading site 35, wherein the transport of the source containers "S1.2 ... S6.2" from the warehouse 1 to the take-off location 33 and the Transport of the target container "Tl ... T6" from the sorting buffer 36 to the loading point 35 are coordinated so that a source container "S1.2 ... S6.2" and a target container "Tl ... T6" to a job in about arrive at the picking place 33 and loading place 35 at the same time.

In the jointly described FIGS. 4a to 4d, a method for order picking of articles at a commissioning station 2 described above is shown, in which the order of the source containers 5 are sorted into a modified sequence.

Basically, the source containers 5 are stored in a disordered (chaotic) order from the bearing 1 and conveyed in a disorderly (chaotic) order on the puff extending portion 23. Optionally, this disordered (chaotic) order of some of the source containers 5 may be changed.

The control unit 26 is set up to determine a modified sequence of the source containers 5, which are required for different order lines for one or more orders. The source containers 5 are then transported in the modified sequence to the take-off place 33. As described above, the control unit 26 may determine the disordered (chaotic) order. In other words, the control unit 26 determines the location of each source container 5 along the transport path between the stock 1, in particular the order determination point 52 and the take-off place 33. If the disordered (chaotic) order is changed, the conveyor 22 is controlled by the control unit 26 in that a single source container 5 or more source containers 5 via the conveyor 22 from the Pufferstreckenab section 23 discharged to the escape buffer 21 and time controlled again from the escape buffer 21 on the Pufferstreckenab section 23 is introduced.

As shown in the embodiment, the source container "Sl. l "for the first order line (position 1), the source container" S3.2 "for the second order line (position 2), the source container" S1.2 "for the second order line (position 2) and the source container" S3.3 " for the third order line (position 3) transported in the buffer section 23 in the specified order. In the sorting buffer 36, the destination containers "T3 to T6" may be buffered, with the destination containers "T4 to T6" being placed on the sorting locations 42-1, 42-2, 42-3, since so far no source containers 5 in FIG the buffer section 23 were transported. The destination container "T3" was moved from the sorting location 42-4 to the buffer space 39-2, and the target container "T3" is still lined up with the destination container "T1." The destination container "T1" is an empty destination container 27 and was conveyed by the conveyor 29 supplied. It should also be noted that an order can be processed at several picking stations 2. In this case, at least one order line of this order and at a second order picking station 2 at least one order line of this order are processed at a first picking 2. As can be seen in FIGS. 4a to 4c, the first source container "Sl. l "is moved past the escape buffer 21. The source container" Sl. 1 "is provided on the take-off location 33 and the destination container T1 on the loading site 35. Then, for the first order line (position 1), an article from the source container "Sl. l "are removed and stored in the target container Tl.

After the last (manual or automatic) removal of an article from the first source container "Sl. A control signal is triggered with this control signal, at least the buffer stretch section 23 and the conveying means 49 on the delivery device 32 being controlled by the control unit 26 in such a way that the source container "Sl. transported away from the removal point 33 and the source container "S3.2" pre-ranked second source container "S1.2" transported to the collection point 33. The source container "Sl. The target container T1 remains at the loading location 35 until the second source container "S1.2" is provided at the removal location 33.

As can be seen in Fig. 4b, the source container "Sl. l "subsequent source container" S3.2 "via the controlled by the control unit 26 conveyor 22 discharged from the buffer section 23 to the escape buffer 21. As can be seen in FIG. 4c, the source container "S1.2" is moved past the source container "S3.2" parked in the escape buffer 21 and transported to the removal location 33. As can be seen in FIG. 4d, the source container "S1.2" is provided at the removal location 33 and it is possible to remove an article from the source container "S1.2" for the second order line (position 2) and deposit it in the destination container T1. After the last (manual or automatic) removal of an article from the source container "S1.2" or last delivery of an article in the destination container "Tl", a control signal is triggered. With this control signal, at least the puff he track section 23 and the conveyor 49 on the Andienungsvorrichtung 32 and the conveyor 50 on the Andienungsvorrichtung 34 and the conveyor 45 on the conveyor 40 and the conveyor 47 at the sorting station 42-4 and optionally the conveyor 31 of the conveyor 30 so controlled by the control unit 26, that the source container "S1.2" transported from the picking place 33, the source container "S3.2" transported to the picking point 33, the previously processed target container "Tl" transported from the loading point 35 and the still to processing target container "T3" be transported to the loading point 35. The target container "T1" can either be buffered in the sorting buffer 36 on one of the sorting locations 42-4, 42-5 or transported to the destination container conveyor.

As can further be seen, after the source container "S1.2" has been transported past the escape buffer 21, the source container "S3.2" via the controlled by the control unit 26 conveyor 22 from the escape buffer 21 on the Pufferstreckenab section 23 is introduced. Thereafter, the source container "S3.2" and this is the source container "S3.3" transported to the collection point 33.

As can be seen from what has been described, some of the source containers 5, for example the source containers "Sl. 1, S1.2, S3.2, S3.3 "are transported in a modified sequence to the loading site 33 and provided in this modified sequence sequentially at the picking location 33.

In the context of the invention, the evasion buffer 21 shown can also accommodate more than one source container 5, for example two, three or four source containers 5. In this case the source container 5 via the conveyor 22 at the same time or sequentially discharged from the puff extending portion 23 to the escape buffer 21 and the escape buffer 21 on the puff he track section 23 are returned. In the jointly described FIGS. 5a to 5c, a method for picking articles at a commissioning station 2 described above is shown, in which the removal of a target container 27 from the loading place 35 is controlled by a picking person. Such a procedural measure applies when the picking person visually determines that a destination bin 27 can not receive all the articles for an order line and an additional destination bin 27 is required to process the remaining quantity of the articles for said order line. In principle, the picking is also possible by means of robots, wherein an acknowledgment signal is triggered when it is determined by the robot or a camera system / a sensor system that a destination container 27 can not receive all articles for one order line and an additional destination container 27 is required to process the remaining quantity of articles for said order line.

As shown in the embodiment, the source container "Sl. l "for the first order line (position 1), the source container" S2.2 "for the second order line (position 2), the source container" S3.2 "for the second order line (position 2) and the source container" S4.2 " for the second order line (position 2) in the puff extending portion 23 transported. In the sorting buffer 36, the destination containers "T3 to T6" may be buffered, with the destination containers "T5, T6" being placed on the sorting locations 42-1, 42-2, since so far no source containers 5 required for these orders have entered the puff-extending section 23 were transported. The destination containers "T3, T4" were moved from the sorting locations 42-3, 42-4 to the buffer locations 39-3, 39-2.

As can be seen in Fig. 5a, the source container "Sl. l "for the first order line (position 1) of a first order on the picking place 33 and the destination bin" Tl .1 "on the loading place 35 are provided. The first order line comprises several articles for a first order, which are stored in several destination containers "Tl. In this case, at least one article is to this first order line in a first target container "Tl. l" and At least one article for this first order line is stored in a second destination container "Tl .2", but the second destination container "Tl .2" must be subordinated to the destination container "T2" since this article has already been transported to the delivery device 34 Source container "S2.2" transported to the delivery device 32.

After the last removal of an article from the source container "Sl. l "and placing this article in the first target container" Tl. l "a control signal is triggered. With this control signal, the conveying means 49 on the delivery device 32 and the (fourth) conveying device 13 and the (sixth) conveying device and the conveying means 50 on the pressing device 34 and the conveying means 45 on the conveying device 40 and the conveying means 47 at the sorting station 42- 4 and the conveyor 31 of the conveyor 30 are controlled by the control unit 26 such that the source container "Sl. l "transported from the take-off point 33, the source container" S2.2 "transported to the take-off point 33, the previously processed target container" Tl. l "transported from the loading point 35 and the still to be processed target container" T2 "are transported to the loading station 35.

In this case, as shown in Fig. 5b, the source container "Sl. 1 "is transported via the (fourth) conveying device 13 and the (sixth) conveying device 22, 25 from the picking station 33 to the buffer section section 23. The target container" T1 "placed on this order is transferred to the destination container conveying system transported. The transport of the target container "Tl. l "from the loading point 35 to the destination container conveyor system via the conveyor 45 of the second conveyor 40, the conveyor 47 at sorting 42-4 and the conveyor 31 of the conveyor 30. In addition, after the triggering of this control signal by the picking the Zielbehälter- Conveyor technology controlled by the control unit 26 such that an empty target container "Tl .2" requested and transported to the loading point 35 for further processing of the first order line to the first order.

If the source container "S2.2" for the second order line (position 2) of a second order on the take-off place 33 and the destination container "T2" on the loading place 35 are provided, then the second order line can be processed, therefore the article (s) taken from the source container "S2.2" and stored in the destination container "T2". After the last removal of an article from the source container "S2.2" and placing this article in the destination container "T2", a control signal is triggered. With this control signal, at least the puff-extending section 23, the conveying means 49 on the delivery device 32 and the conveying means 50 on the delivery device 34 are actuated by the control unit 26 such that the source container "S2.2" is transported away from the removal location 33, the source container "Sl. l" repeated from Puffabschnitt 21 extended to the removal point 33, the previously processed target container "T2" transported away from the loading point 35 and the still to be processed target container "Tl .2" are transported to the loading point 35. The destination container "T2" is transported from the loading station 35 back into the sorting puff 36 and to a sorting station 42-3 determined by the control unit 26, since a third order line (item 3) is still to be processed.

Are the source container "Sl. l "for the first order line (position 1) of a first order on the picking place 33 and the destination bin" Tl .2 "provided on the loading place 35, as shown in Fig. 5c, so the first order line (ready) can be processed, therefore the (remaining) article from the source container "Sl. l "and stored in the target container" Tl .2 ". The target container "T1 .2" picked for this order is either transported to the destination container conveyor or into the sorting buffer 36. In the exemplary embodiment described, the destination containers "T1 .1, T1.2" were provided as empty destination containers 27. It is also possible that the first target container 27 already contains articles and therefore in this target container 27, the articles can not be accommodated to the first order line. For example, the article about the first order line is too big. In this case, the control signal is triggered after it has been determined that an article in the first target container 27 can not be stored. It does not necessarily require the removal of an article from the source container 5 to trigger a control signal.

In the jointly described FIGS. 6a to 6c, a method for order picking of articles at a commissioning station 2 described above is shown in which the control unit 26 based on a "load-specific" characteristic value (and without control intervention by a picking person) first laden destination container 27 is transported away from the loading station 35 and a second empty destination container 27 is sent to the loading location 35. are transported, since the first target container 27 can not receive all the articles for an order line and at least one additional target container 27 is required to process the remaining quantity of the articles for said order line. For this purpose, for each article of an order with one or more order lines, at least one article-specific characteristic value is for example electronically recorded on a computer and processed by the control unit 26. In particular, a dimension for each article, such as the weight and / or volume and / or geometric shape is detected as the article-specific characteristic value.

In a first step, the control unit 26 determines a job-specific characteristic value for each article based on the one or more order lines that are processed for a job and the article-specific characteristic values. In particular, a total volume or total weight of all articles for a job or a loading configuration (finishing pattern) for the articles in the destination container 27 is determined as an order-specific characteristic value.

In a second step, the control unit 26 determines a load-specific characteristic value of at least one destination container 27 in which the articles for the named order are to be stored. In particular, as an order-specific characteristic value, an available loading volume or maximum loading weight or which articles can still be picked up in the target container due to their geometry shapes can not be recorded. In other words, it is also considered whether the target container 27 is empty or already partially filled. Thus, for example, an article with small dimensions can still be accommodated in the target container 27, while an article with large dimensions must be deposited in an additional target container 27.

In a third step, the control unit 26 determines the number of additionally required second target containers 27 for processing said order based on the job-specific characteristic value and load-specific characteristic value, if an article in the first target container 27 can not be stored. If no second target container 27 is required, then the number is zero. According to this preliminary calculation by the control unit 26, the provision of the target containers 27 in the required number and the provision of the source containers 5 are coordinated. As shown in the embodiment, the source container "S 1.1" for the first order line (position 1), the source container "S5.2" for the second order line (position 2) and the source container "S3.3" for the third order line (position 3) in the buffer path section 23. In the sorting buffer 36, the destination containers "T2, T3, T5, T6" may be buffered, with the destination containers "T2, T6" placed on the sorting locations 42-1, 42-2, as yet no source containers 5 required for these jobs were transported into the buffer line section 23. The destination containers "T3, T5" were moved from the sorting locations 42-3, 42-4 to the buffer locations 39-3, 39-2.

As can be seen in FIG. 6a, the source container "S4.1" for the first order line (position 1) of a fourth order on the take-off location 33 and the destination container "T4" on the loading space 35 are provided. Then, for the first order line (position 1), an article is taken from the source container "S4.1" and placed in the destination container "T4". After the last removal of an article from the source container "S4.1" and placing this article in the target container "T4", a control signal is triggered and proceed in the manner described above. Therefore, the target bin "T4" is transported into the sort buffer 36 and the sort bin 42-3, and the source bin "S4.1" is transported to the source bin conveyor. In addition, after the triggering of this control signal by the picking person, the target container conveying system is controlled by the control unit 26 in such a way that an empty target container "Tl .2" is requested and to the loading location 35 for further processing of one order line or several order lines to one order or transported several orders.

As can be seen in Fig. 6b, the source container "Sl. l "for the first order line (position 1) of a first order on the picking place 33 and the destination bin" Tl .1 "on the loading place 35 are provided. The first order line comprises several articles for a first order, which must be stored in several destination containers "T1." As not shown further, the first order may also comprise a second order line (position 2) Control unit 26 the required Determined number of target container 27 and accordingly the target container 27 is provided in succession on the loading point 35.

As shown, the first order comprises a first order line (position 1), the number of articles can not be accommodated in a single target container "Tl .1".

For now, the articles for this first order line from the source container "Sl. l "and stored in the first target container" Tl. L "filed. After the last removal of an article from the source container "Sl. l "and placing this article in the first target container" Tl. L "is triggered by the control unit 26, a control signal. With this control signal, the conveying means 50 on the delivery device 34 and the conveying means 45 on the conveying device 40 and the conveying means 47 on the sorting station 42-4 and the conveying means 31 of the conveyor 30 are controlled by the control unit 26 in such a way that the first target container previously processed "Tl. l "transported from the loading point 35 and the additional second target container" Tl .2 "are transported to the loading point 35. The target container "Tl. l "is transported in the manner described above onto the target container conveying system. The source container" Sl. l "remains at the loading location 35 until the second target container" T1 .2 "is provided at the loading location 35.

As can be seen in Fig. 6c, the source container "Sl. l "for the first order line (position 1) of the first order on the picking place 33 and the destination bin" Tl .2 "on the loading place 35.

Then, for the first order line (position 1), an article from the source container "Sl. l "taken and stored in the target container" Tl .2 ". After the last removal of an article from the source container "Sl. l "and placing this article in the target container" Tl .2 ", a control signal is triggered and moved in the manner described above. Therefore, the target bin "Tl .2" is transported to the sorting buffer 36 or to the target bin conveyor. The source bin "Sl. L" is transported to the source bin conveyor. In the mentioned embodiment, the first target container "Tl. 1 "for the processing of the first order line (position 1) Therefore, the first destination container" T1 "has been provided as an empty destination container" T1.1 "by the destination container conveyor, otherwise it is also possible that the first Target container "Tl. L" from the sorting buffer 36 and transported to the loading point 35, since this already contains an article and can be additionally loaded with an article. In order to be able to process the order line or the order, an empty destination container 27 is then provided by the destination container conveyor as the second destination container 27. In the jointly described FIGS. 7a to 7d, a method for picking articles at a commissioning station 2 described above is shown in which a first loaded one of the control unit 26 based on a "load-specific" characteristic (and without control intervention by a picking person) Target container 27 (bypassing the loading point 35) transported away from the sorting buffer 36 and a second empty destination container 27 are transported to the loading station 35 to edit the remaining amount of articles for a job line or multiple order lines to a job.

For this purpose, the procedure described above is followed and the number of required destination containers 27 determined in advance by the control unit 26 and the provision of the destination containers 27 and source container 5 coordinated.

As shown in the embodiment, as shown in FIG. 7a, the source container "S3.2" for the second order line (position 2), the source container "S1.2" for the second order line (position 2) and the source container "S5.2" for the second order line (position 2) is transported in the buffer path section 23. In the sorting buffer 36, the destination containers "T1, T2, T5, T6" can be buffered, the destination containers "T2, T6" being located on the sorting locations 42-1, 42 -2, since no source containers 5 required for these jobs have yet been transported into the buffer path section 23. The destination container "T5" has been moved from the sorting location 42-3 to the buffer space 39-3.

As described above, the unordered order of the source containers 5 in the puff extending section 23 is evaluated by the control unit 26. Likewise, by the control unit 26th After the order of the source containers 5 is "almost" arbitrary, the case may arise that a source container "S1.2" for the processing of the second order line is transported to the take-off location 33 , which contains an article that can no longer be stored in the target container "Tl. 1" due to its geometric dimension. For this case, it is provided that the target container "Tl. l "is not even transported to the loading location 35, but is transported away from the sorting buffer 36. If the destination container" T1. "has previously been moved to one of the buffer locations 39-2, then it is moved from the buffer location 39-2 via the sorting location 42 -4 transported to the destination container conveyor.

It is triggered by the control unit 26, a control signal, after it has been determined that an article in the first target container "Tl. With the control signal, at least the conveying means 47 of the third conveying device 43 and the conveying means 31 of the conveying device 30 are controlled by the control unit in such a way that the first target container "T1", which can not be filled further, from the sorting buffer 36 onto the target containers Conveyor technology is removed, as shown in Fig. 7b.

In addition, after the triggering of this control signal, the destination container conveyor technology can be controlled by the control unit 26 such that an empty destination container "Tl .2" is requested and transported to the loading location 35 for further processing of an order line or several order lines to one or more orders. Meanwhile, the first order line (position 1) can be edited to a fourth order.

As can be seen in Fig. 7c, thereafter the target container "T3" on the loading place 35 and the source container "S3.2" on the take-off place 33 are provided in the manner described above. Previously, for the first order line (item 1), an article was taken from the source container "S4.1" and placed in the destination container "T4". The source container "S4.1" is transported to the source container conveyor and forwarded to the destination container "Tl. L". Finally, the empty target container "Tl .2" is provided on the loading place 35 and the source container "S1.2" on the take-off place 33 in the manner described above, as shown in Fig. 7d. Thereafter, for the second order line (position 2), the at least one article is taken from the source container "S1.2" and stored in the destination container "T1 .2". After Last removal of an article from the source container "S1.2" and placing this article in the target container "Tl .2", a control signal is triggered and proceed in the manner described above. Therefore, the target container "Tl .2" is transported to the sorting buffer 36 or to the target container conveyor. The source container "S1.2" is transported to the source container conveyor.

Hereinafter, a method for picking returned goods using the picking station 2 described above in FIGS. 1 and 2 will be described. The picking station (s) 2 and the order-picking system can be used either in a picking mode for picking articles from the source containers 5 into destination containers 27 or in a return mode for picking returned items from returned goods containers 53 into the source containers 5. Accordingly, the disclosure is to be transferred analogously to this embodiment. For reasons of better understanding, the changed nomenclature is entered in FIG. In Retourniermodus the take-off point 33 as loading point 35 for providing the source container 5, the loading point 35 as a take-off point 33 for providing the Retourwar enb ehälter 53, the destination container distribution system as Retourwar enb ehälter- distribution system 4 'for transporting the filled return goods enb ehälter 53 to Take-off place 33 and for the removal of emptied return goods containers 53 from the take-off place 33 are used. The returned goods distribution system comprises a returned goods conveyor system. The returned goods conveying system can, for example, be a first conveying device 29 'for transporting filled returned goods to the respective picking station (s) 2 and a second conveying device 30' for removing empty returned goods from the picking station (s) concerned (FIG. en) 2. The return goods container distribution system 4 ', in particular the first conveying device 29' for transporting filled return goods containers 53, can also connect to the sorting buffer 36. The first conveying device 29 'can also be connected to the source container distribution system, in particular the fifth conveying device. In this case, returned goods containers 53 can also be transported, for example, from the warehouse 1 or from a provisioning station 54 connected to the source container distribution system. At the parking space 54, the returned goods are provided. In the jointly described Fig. 9a to 9f a method for picking returned goods at a commissioning station 2 is described, are processed in the depository orders. In the embodiment shown, a provisioning station 54 is provided which connects to the recycling container distribution system 4 'for transporting the filled return goods container 53. At the parking space 54 return goods containers 53 are provided. In this case, the returned goods may have already been deposited in the returned goods containers 53 or the returned goods may be stored there manually / automatically in the returned goods containers 53.

The Retourwarenb ehälter 53 is preferably divided by partitions into a plurality of receiving compartments and can accommodate different types of returned goods, in the first receiving compartment a return goods type "A" and in the second receptacle a return goods type "B" can be added. Basically, it is also conceivable that the return goods types are included as bulk goods in Retourwarenb ehälter 53. At least some of the returns recipients 53 thus each contain a plurality of different return goods types.

At the parking space 54, the returned goods containers 53 to be processed and the returned goods stored in the returned goods containers 53 are identified and return storage orders are recorded electronically on a computer (not shown). The return orders are transmitted to the control unit 26 (FIG. 1) and are available as data records. The return goods container 53 contains the returned goods for several backorder orders. Each backorder order includes at least one returned item. The control system 26 determines from the existing source containers 5 in the warehouse 1 to which of these source containers 5 the returned goods can be assigned. The returned goods and the source container 5 are linked together at this point in terms of data technology.

After that, the returned goods containers 53 are transported from the provisioning station 54 to the sorting buffer 36 and to one of the sorting stations 42.

The source containers 5 are, as described above, outsourced from the stocker 1 in a disordered (chaotic) order and in a disordered (chaotic) order promoted to loading point 35. The order in which the source containers 5 are conveyed to the loading place 35 can deviate from the order in which the source containers 5 are transferred out of the store 1. Preferably, the source containers 5 each store a single item type. Although the source containers 5 are fed to the loading site 35 in a disordered order, this order is detected at the ordering destination 52 (Figure 1) sorted in an order determined by the order of the source containers 5. In Fig. 9a, the source container "Sl" for the returned goods "Rl" is located at the loading site 35 and the returned goods container "Rl, 2" is located at the collection site 33. It is the returned goods "Rl" from the Retourwarenb ehälter "Rl, 2" removed and stored in the source container "Sl".

If picking by a picking person, so an input and output system 51 is provided with an acknowledgment button and a display. The display comprises a display field by means of which a numerical or alphanumeric (visual) output of order-picking instructions can take place. For example, the picking person is signaled on the display which returned goods are to be taken from the return goods container "R1, 2" and deposited in the source container 5. In the example shown, the returned goods "R1" are to be taken. After the last removal of an article from the Retourwarenb ehälter "Rl, 2" or after the last delivery of a returned goods in the source container "Sl" a control signal is triggered, if the order picker presses the acknowledgment button on input and / or output system 51. After the last (manual or automatic) removal of an article from the return container "Rl, 2", a control signal is triggered With this control signal, at least the buffer section 23 and the conveyor 49 on the delivery device 32 and the delivery device 50 on the delivery device 34 and the conveyor 45 on the conveyor 40 controlled by the control unit 26 such that the source container "Sl" transported from Beladeplatz 35, the source container "S3" transported to the loading point 35, the previously processed Retourwarenb ehälter "Rl, 2" of the Removal point 33 transported away and the still to be processed Retourwarenb ehälter "R 3, 4" transported to the take-off point 33. In addition, it can be seen that the returned merchandise container "R7, 8" has already been moved from one of the sorting locations 42-2 to one of the buffer locations 39-4, after at least one of the source containers "S7, S8" associated with these returned items for depositing a returned item (to a deposit order) in the puff section 23 was transported. On the other hand, the return goods containers "R9, 10, R1" are temporarily buffered at the sorting locations 42-1, 42-3 at least until the source containers "S9, S10, SU" assigned to these returned goods (for a return deposit order) ) extending the puff section 23 is conveyed. Within the scope of the invention, it is also possible for some of the returned goods containers, for example the returned goods container "Rl 1", to contain only one return type of goods R9, 10 ", however, contain different types of returned goods, which significantly increases the efficiency of the picking system for picking returned goods. As can be seen in FIG. 9b, the previously processed return goods container "R1, 2" is transported from the picking station 33 back into the sorting buffer 36 and to a sorting station 42-4 determined by the control unit 26, since the returned goods "R2" are still in the Returned goods are included. The source container "Sl" is transported on the source container conveyor system from Beletzplatz 35 and stored back into the warehouse 1. The source container "Sl" now contains the stock items and the returned item.

If the source container "S3" is provided on the loading site 35 and the return goods container "R3, 4" is provided on the removal site 33, the returned product "R3" can be removed from the returned product container "R3, 4" and deposited in the source container "S3" After the (manual or automatic) removal of the returned good (s) from the returned goods container "R3, 4", a control signal is triggered. With this control signal, at least the buffer stretch section 23 and the conveying means 49 on the delivery device 32 and the conveying means 50 on the delivery device 34 and the conveying means 45 of the conveying device 40 are controlled by the control unit 26 in such a way that the source container "S3" is removed from the loading station 35 - Ported, the source container "S6" transported to the loading point 35, the previously processed Retourwarenb ehälter "R3, 4" transported from the unloading place 33, the still to be processed Retourwarenb ehälter "R5, 6" are transported to the removal point 33. Of the The previously processed return goods container "R3, 4" is transported from the picking station 33 back into the sorting buffer 36 and to a sorting station 42-2 determined by the control unit 26, since the The returned goods container "R7, 8" is transported via the conveyor 44 from the buffer space 39-4 to the buffer space 39-3.

As also indicated in this figure, a return goods container "R12" is provided at the provisioning station 54 and supplied to the returned goods container distribution system 4. This return container "R12" is transported from the returned goods container distribution system 4 'to the sorting buffer 36, as follows described.

As can be seen in FIG. 9c, the return goods container "R2" can be moved directly from the sorting location 42-4 to one of the buffer locations 39-2 determined by the control unit 26 and then to the delivery device 34 after the source container "S2" has already been moved into the Pufferstreckenab section 23 has been transported. The return goods container "R2" is transported from one of the sorting places 42-4 to one of the buffer places 39-2 by means of the conveying means 46, 47 of one of the third conveying devices 43. The conveying means 46, 47 are actuated by the control unit 26. The returned goods item ehälter "R2" is moved past the retort containers "R9, 10, R4" which are temporarily buffered in the sorting buffers 42-1 to 42-2 in the sorting buffer 36. Thus, a sorting process is carried out from the sorting buffer 36 via the sorting sites 42-1 to 42-5 In the meantime, the source container "SU" has been transported into the buffer section 23. Thus, the return goods container "Rl 1" can also be moved from one of the sorting stations 42-2 to one of the buffer stations 39-4 via the conveying means 46 of one of the third conveying devices 43. The return goods container "R7, 8" is conveyed via the conveyor 44 of FIG the buffer space 39-3 transported to the buffer space 39-2.

If the source container "S6" provided on the loading point 35 and the Retourwarenb ehälter "R5, 6" on the take-off point 33, the returned goods "R6" from the Retourwarenb ehäl- ter "R5, 6" removed and stored in the source container "S6" After the (manual or automatic) removal of the returned good (s) from the returned goods container "R5, 6", a control signal is triggered. Thus, in the manner described above, the source container "S6" transported from the loading point 35, the source container "S2" transported to the loading point 35, the previously processed Retourwarenb ehälter "R5, 6" transported from the take-off point 33, the still to be processed Retourwarenb ehälter "R2" are transported to the take-off place 33rd The source container "S6" is transported via the source container conveyor. The previously processed Retourwarenb ehälter "R5, 6" is transported from the picking place 33 back into the sorting buffer 36 and to a specific sorting station 42 determined by the control unit 26, since even the returned goods "R5" is contained in Retourwarenb ehälter. As can be seen in FIG. 9d, the source container "S2" for the returned item "R2" is located at the loading location 35 and the returned item holder "R2" at the removal location 33. The returned item "R2" is removed from the returned item holder "R2" and stored in the source container "S2". After the (manual or automatic) removal of the last returned goods from the return goods container "R2", a control signal is triggered.

With this control signal, at least the puff-extending section 23 and the conveying means 49 on the delivery device 32 and the conveying means 50 on the delivery device 34 and the conveying means 45 of the conveying device 40 are controlled by the control unit 26 such that the source container "S2" from the loading place Transported 35, the source container "S8" transported to the loading station 35, the previously processed (empty) Retourwarenb ehälter "R2" transported from the picking place 35, the still to be processed Retourwaren- container "R7, 8" are transported to the picking place 35. The source container "S2" is transported away via the source container conveyor system and the return container "R2", which has been completely emptied for this return order, is transported to the returned goods container conveyor system. The transport of the Retourwarenb ehälters "R2" from the removal point 33 on the returned goods container conveyor technology via the conveyor 45 of the second conveyor 40, the conveyor 47 at the sorting 42-4 and the conveyor 31 of the conveyor 30, as shown in Fig.9e. The source container conveyor system is preferably also used as a returned goods container conveyor system and the return goods container "R2" is discharged from the conveyor system 30 onto the conveyor system 13 before or after the source container "S6", as entered in FIG. R2 "is transported to an empty container collecting station (not shown) so that it can later be used again as returned goods container 53. As can be seen in Fig. 9f, the returned goods container with the returned product "R12" is transported from the optional conveyor 29 'to the sorting buffer 36. Thereafter, the return container "R12" is transferred to the sorting buffer 36, the control unit 26 transferring the product. the means 47 for the buffer space 39-1 and the conveying means 47 for the sorting station 42-5 drives in such a way that the return goods container "R12" is transported by the conveyor device 29 'to the sorting station 42-5. can be transported via the conveyor 45 to a free sorting station 42-1 to 42-5, for example the sorting station 42-1, determined by the control unit 26.

In principle, it would also be conceivable for the returned goods container "R12" to be transported directly from the conveyor device 29 'to the removal station 33. This may be the case when a first returned goods container 53 is to be processed from a number of returned goods containers 53, It is to be ensured that the source container 5 assigned to this returned goods container 53 can likewise be provided.

In this way, the backorder orders are processed one after the other.

Based on this embodiment, it will be seen that a first Retourwarenb ehälter 53 for processing deposit orders after depositing a returned goods to a first deposit order transported back into the sorting buffer 36 and at least temporarily buffered on a first sorting station 42 until a source container 5 for storing a returned goods for a second return order in a provided upstream of the loading point 35 Puff ausbab section 23 is promoted. Said first returned goods container 53 can be moved from the first sorting station 42 to one of the buffer locations 39 and then to the removal station 33, after the source container 5 has been transported to deposit a returned product for a second return order in the puff section 23.

In this case, according to a first procedure, for example, the return goods container "R2" is moved immediately after it has been transported to buffer space 39 to take-off station 33 (see, for example, FIGS. 9b to 9d) "in the order of the returned goods containers" R2 ... RH "on the buffer spaces 39, another returned goods container" R4 "is lined up and the said return goods container "R4" only after the pre-arranged Retourwarenb ehälter "Rl 1" to the take-off station 33 moves (see, for example, Fig. 9c and 9d). In the operation of the sorting buffer 36, both procedures usually occur. On the other hand, it can also be seen from this embodiment that a second Retourwarenb ehälter 53 for processing depository orders after depositing a returned goods to a first deposit order back transported to the sorting buffer 36 and a second sorting station 42 to one of the buffer sites 39 and then to the take-off 33 is moved, if a source container 5 for depositing a returned goods to a second depository order has already been transported in the provided upstream of the take-off point 35 Puff extending section 23.

The return goods containers 53 are transported from the sorting buffer 36 in the sorted sequence and consecutively to the unloading station 33, whereby the transport of the source containers 5 from the warehouse 1 to the loading location 33 and the transport of the returned goods containers 53 from the sorting buffer 36 to the unloading station 33 are in succession are agreed that a source container 5 and a Retourwarenb ehälter 53 arrive at an order at about the same time at the loading point 35 and unloading point 33.
