Description

Device and method for picking articles

The invention relates to a device and a method for picking articles from storage containers according to at least one order into at least one order container, in which: Storage containers are removed from an article warehouse by means of one of a plurality of storage vehicles, the storage containers being in the article warehouse are stored one above the other to form a plurality of vertical stacks arranged one on top of the other, the storage vehicles being movable on a rail system arranged above the vertical stacks of the article warehouse and being positionable above the vertical stacks for removal of the storage containers; the removed storage containers are fed to at least one transfer station; Articles are transferred from the supplied storage containers to a sorting system; and the items by means of the sorting system at a picking station

Picking the order are provided in the at least one order container.

State of the art

So-called grid storage systems are known from the prior art (DE 10 2018 251 752 A1, WO 2016/198467 A1), in which storage containers are stacked on top of one another and arranged next to one another in the form of a grid. Storage vehicles move on a grid above the store, which can remove storage containers from above and transport them along the grid. However, such grid storage systems suffer from the fact that in order to provide a specific item, the associated storage container must first be “digged up” by the storage vehicle. If the articles are now to be picked in a specific sequence, the storage containers must first be temporarily stored in a buffer, which blocks the storage containers for a long time and severely limits the throughput. The storage containers are therefore usually made available unsequenced in buffers at the picking stations, with the picking staff providing the required

Removes items from the appropriate storage bins.

It is also known from WO 2017/097724 A1 to transfer the storage containers from a grid storage system to a plurality of conveyor chutes in order to form a sequence, it being possible for the storage containers in the conveyor chutes to have a predetermined sequence in each case. However, to form the sequence in the conveyor chutes, the storage bins must be provided in the correct order, which in turn severely limits the throughput of the system as some storage bins may be excavated from a deep position in the camp

need and require a correspondingly long period of time for the provision.

Grid storage systems are also known from WO 2019/238664 A1, in which vertical shafts are provided which are designed for transferring storage containers from a grid above the grid storage system to a transport grid below. The storage vehicles can lower the storage containers in the shafts and place them on a storage vehicle in the lower transport grid or hand them over to this. The lower grid has picking stations where the storage containers can be made available by means of the storage vehicles. At the picking stations, the picking person can then select the items according to an order from the storage containers provided

pick into the order container.

Also known from EP3650374 are A1 grid storage systems with a connected sequencing buffer. The sequencing buffer can be rotated, with the operator at the picking station being able to request the provision of a specific storage container from the sequencing buffer. However, such systems again suffer from the limited space in the sequencing buffer and from the long deployment time when a

storage container is not available in the sequencing buffer.

Disclosure of Invention

The present invention has therefore set itself the task of improving a method for picking articles of the type mentioned at the outset in such a way that the efficiency in the picking of articles from the article warehouse and the throughput

of the process can be further increased in a cost-effective manner.

The invention solves the problem set with regard to the method in that the articles of the at least one order are transferred to a sorting system in the order in which the storage containers were made available at the transfer station in a first picking step and are stored in the sorting system independently of the order in which the articles were handed over sorts a designated sequence and the items in the order of the designated sequence

be fed to the picking station.

If the items of the at least one order are transferred to the sorting system in the order in which the storage containers are made available at the U transfer station and sorted in the sorting system in a planned sequence regardless of the order in which the items are transferred, the process for making the storage containers available can be significantly simplified and the throughput can be increased since the storage containers can be made available at the transfer station by means of the storage vehicles from the article warehouse in any order. In this way, intermediate buffers for storage containers

avoided and time-consuming rearrangements of the storage containers in the article warehouse reduced

and the storage containers are simply made available in the order in which they arrive at the transfer station by the storage vehicles driving independently of one another and in parallel. The desired articles can then be transferred to the sorting system immediately after the arrival of the storage container at the transfer station without major delays and sorted into a predetermined sequence by the sorting system regardless of the order in which the articles were transferred. Since the items do not have to be provided in a specific sequence by the warehouse vehicles,

in particular traffic jams and road collisions between the storage vehicles are avoided.

A large number of transfer stations can preferably be provided, with a storage container always being fed to the transfer station that is closest to it and

thus reducing the travel distances of the storage vehicles.

Preferably, the articles are then further fed to the picking station in the order of the intended sequence and can be picked directly into the order container or containers. In particular, the items can easily be picked into the order containers by machine or by hand, without having to first create a particular sequence. In this way, in particular, picking errors that occur as a result of sorting at the picking station can be reliably avoided. A particularly simple and quick picking of the articles in the order container at the picking station can be achieved in this way. According to the invention, a technically simple method for picking articles with a high throughput can thus be created

which is also cost-effective to implement.

An order within the meaning of the present invention is, for example, a customer order for the delivery of articles to the customer, a branch order for the delivery of articles to a branch (e.g. for replenishment), a parts list order for the assembly of an article from several partial articles Transfer order for consolidation (e.g. of returns) or the like. Such orders may, among other things, require the delivery of the items in a specific order or sequence in the order container. In the case of branch orders in particular, a packing image can be specified and the items can be delivered sorted according to size, colour, type, etc. in order to order the items

to be processed further in the branch without much effort.

A storage vehicle within the meaning of the present invention is understood as meaning any manually, remotely or computer-controlled vehicle which is designed to receive and transport storage containers from or into the article warehouse. Such a warehouse vehicle can be, for example, remote-controlled vehicles, vehicles with

two sets of wheels that can move along two orthogonal directions,

be rail-bound vehicles or the like. Such storage vehicles can be equipped with load handling equipment, for example, which is used to lift and move storage containers

are trained.

In particular, in a further embodiment variant, only those articles that belong to a coherent order can be fed to the picking station in the specified sequence. This can reduce the susceptibility to errors

picking of items into wrong order containers can be further reduced.

The method according to the invention is also particularly suitable for full automation, in particular in which the transfer of articles from the storage containers to the sorting device and the picking of the articles into the order container on

Picking place done by robots.

The method according to the invention is characterized in particular by the fact that the delivery of the articles in the intended sequence to the picking station enables uninterrupted picking of all articles of the at least one order into the at least one order container at the picking station. In particular, with the method according to the invention, there is no longer any further sorting of the articles at the picking station. The susceptibility of the method to errors in the final step of picking can thus be significantly reduced compared to the methods known from the prior art. A particularly simple and reliable method can be so

be created.

If the intended sequence for picking articles from several orders from storage containers into several order containers corresponds to an uninterrupted sequence of articles belonging to one order, the method according to the invention can be further improved. In particular, the sorting device can bring the articles into a planned sequence, which corresponds to a juxtaposition of articles belonging to one order. At the picking station, the items can simply be picked in the order in which they arrive without further sorting into the order containers of several orders. A particularly reliable picking method can be created as the susceptibility to errors when picking the items in the

Order container is significantly reduced.

Furthermore, if the intended sequence corresponds at least partially to a sequence of the articles in the order container that is to be adhered to according to an order, the reliability of the method can be further increased. In particular, orders can be picked reliably and easily, in which a certain sequence or order in

order container must be complied with. This can be the case, for example, when picking

Items of different sizes and/or colors, variants, etc. in an order container can be useful, the predetermined order of the items in the order container corresponding, for example, to the order in which the items are presented in a shop

are, or kept in a warehouse.

The method can be characterized in particular by high efficiency and high throughput if, for the essentially parallel picking of articles in a group of orders, the storage containers for fulfilling all orders are removed from the article warehouse by means of a large number of storage vehicles and in any order of their arrival are transferred to the sorting system at the at least one transfer station. A group of orders can be formed from a large number of orders to be picked, which is processed essentially in parallel. In particular, in order to fulfill several orders from the group, which include the same articles, the storage containers have to be made available only once at the transfer station. The articles are then preferably each individually handed over to the sorting system and provided in a predetermined order at the picking station, so that the orders from the group into the

respective order container can be picked.

The storage containers with the items required to fulfill all orders from the group are then removed from the item warehouse by the storage vehicles in parallel and independently of one another and in the order in which they arrive at the U transfer station

provided.

If, in addition, a corresponding number of articles are taken from the respective storage containers to fulfill all orders from the group of orders and fed to the sorting system, the effort required to provide them by the storage vehicles can be further reduced. For example, if one and the same article is required to fulfill several orders, the storage container with these articles can only be provided once at the at least one transfer station and the corresponding number of

articles can be removed.

After the storage containers have been made available at the transfer station by means of the respective storage vehicles, the articles of the at least one order can be removed from the storage containers and transferred individually into transport containers of the sorting system. By separating the articles into the transport containers, the sorting of the articles into the specified sequence can be further simplified. Furthermore, by supplying individual articles in a respective transport container to the picking station, the picking of the articles and, in particular, an automation of the picking

be simplified.

According to a preferred embodiment variant, the transport containers can be transport bags that are transported by means of an overhead conveyor. The sorting device can thus have such an overhead conveyor for conveying the conveying pockets. A particularly compact one

and space-saving system can be created.

After the removal of the items and their provision at the transfer station or their transfer to appropriate transport containers, the storage container by means of the respective

Warehouse vehicles are stored again in the article warehouse.

The invention has also set itself the task of providing a system for picking articles of the type mentioned with a high throughput that a cost-effective and reliable picking of articles in order containers in a

predetermined sequence allows.

The object is achieved in that the sorting system is a matrix sorter, which is coupled to the transfer station with the transport system for transferring articles from the storage containers to the transport containers of the matrix sorter and which sorts the

Transport container and is designed to form the intended sequence of articles.

If the sorting system is a matrix sorter, the transport containers with the articles can be brought into the intended sequence in a simple and reliable manner as they pass through the matrix sorter. In particular, the use of the matrix sorter completely eliminates the need for buffer spaces for the storage containers at the transfer station. The time during which a storage vehicle is occupied with a storage container and during which the storage container is on the way between the article warehouse and the transfer station can be significantly reduced. In this way, throughput can be increased when deploying

Storage containers from the article warehouse are further increased.

In particular, the throughput in the provision of storage containers from vertically arranged article warehouses is usually limited by the available buffer spaces and the number of storage vehicles required for sequencing the articles. Due to the complete elimination of the buffer locations and the downstream connection of a matrix sorter after the article warehouse, the sequencing can be completely shifted to the matrix sorter,

whereby a system with high throughput can be created.

According to the invention, the matrix sorter is coupled to the transport system of the article warehouse at the transfer station, so that articles can be transferred from the storage containers provided to transport containers of the matrix sorter. the

Articles in the transport containers can then be reliably sorted into the

provided sequence are brought and in this sequence at the picking station

to be provided.

The matrix sorter can have at least one sorting loop with associated points for the transport container, so that with appropriate switching of the points any

Sequence of items can be sorted into a designated sequence.

If, according to a further embodiment of the invention, the transport containers are designed as transport pockets and the matrix sorter has an overhead conveyor system (pocket conveyor system) for transporting and sorting the transport pockets, a particularly space-saving and cost-efficient system can be created. In particular, the conveyor pockets can flexibly accommodate any type and size of article

complex conveyor systems with conveyor belts and transport containers can be dispensed with.

If the sorting system is also connected to the picking station and the picking station has an unloading point for removing the items from the transport containers, the transport bags can be made available in the intended sequence after passing through the matrix sorter directly at the unloading point of the picking station without any further steps. This can increase the efficiency of the device

be further increased.

According to a further embodiment variant, the matrix sorter can be connected to a second conveyor system in order to provide second articles from a second article store at the matrix sorter. In this way, parallel to the provision of the articles from the first article warehouse at the transfer station, second articles can also be made available from a second article warehouse, with all articles then being brought into the intended sequence by means of the matrix sorter. This can be particularly advantageous if articles are also to be picked that cannot be conveniently stored in the storage containers in the article warehouse (for example in the case of hanging goods such as

clothing or the like).

The second conveyor system can also be designed to transfer the second article from the second storage container into the transport container at the transfer station. In this way, second articles that are stored in second storage containers in the second article warehouse can simply be transferred to the transport container at the transfer station in order to

Matrix sorters are sorted together with the articles from the first article warehouse.

In a further embodiment variant, the second conveyor can also be an overhead conveyor system, for example, which transports the second article directly into the

overhead conveyor system of the matrix sorter.

In yet another embodiment variant, the picking station can be connected to a third conveyor system in order to supply third articles from a third article warehouse to the picking station for picking the articles according to the at least one order into the at least one order container. This can prove particularly advantageous when additional items are to be picked that cannot be transported in the transport containers, in particular in the conveyor pockets, of the matrix sorter, or that cannot be transported in the overhead conveyor system of the matrix sorter. These third items can be, for example, large, bulky items or particularly heavy items. These third articles are then preferably fed directly by means of the third conveyor system in their own storage containers from the third article warehouse to the picking station, where they can be picked into the corresponding order container. A particularly flexible system, which offers a multitude of different

Articles can pick, can thus be created.

The system according to the invention preferably has a controller which programs in this way

is to carry out a method according to claims 1 to 9 using the system.

Ways to carry out the invention

The embodiment variants of the invention specifically described below represent only a few possible embodiment variants and are not intended to be limiting

Scope of protection to be understood according to the claims.

1 shows a schematic plan view of the system 100 according to the invention for picking articles 1 according to at least one order from storage containers 2 into at least one order container 3. The system 100 is used to

Picking the items 1 a method 200 according to any one of claims 1 to 9

executed. Preferred embodiment variants of the system 100 and the method 200

result from the following description.

As shown in FIG. 1 and in the perspective representation of the system 100 in FIG. 2, the system 100 has at least one article store 4 in which the storage containers 2 are stored one above the other to form a plurality of vertical stacks 5 arranged next to one another. The storage containers 2 are preferably designed as cuboid boxes that can be stacked directly one on top of the other and thus form a vertical stack 5 . The storage containers 2 preferably always contain items 1 of a single type, with the items 1 of a type in

several storage containers 2 distributed over the article warehouse 4 can be included.

A transport system 6 is coupled to the article store 4 and has a rail system 7 which is arranged above the vertical stacks 5 of the article store 4 . The rail system 7 has rails 8 in the x-direction and rails 9 in the y-direction, along which storage vehicles 10 can move. The storage vehicles 10 are designed for removal, storage and transport of storage containers 2, with a

Storage vehicle 10 can preferably handle only one storage container 2 at a time.

If a storage container 2 is requested from a lower position in a stack 5, it must first be “excavated” by the storage vehicles 10; the overlying storage containers 2 must therefore first be removed before a storage vehicle 10 can accommodate the desired storage container 2 . According to one embodiment variant, the storage containers 2 located above can each be picked up by a storage vehicle 10 and temporarily held in it until the desired storage container 2 can be picked up by another storage vehicle 10 . After the desired storage container 2 has been removed, the temporarily held storage containers 2 are stored again in the stack 5 . In a further embodiment variant, the storage containers 2 lying above them can also be relocated from one storage vehicle 10 to another stack 5 until the desired storage container 2 can be removed. In a preferred embodiment variant of the method 200 according to the invention, the two embodiment variants described above are dynamically carried out alternately or simultaneously, depending on the available (free) storage vehicles 10 and available spaces in stacks 5 .

The system 100 is preferably equipped with a controller 50 which detects and stores the position of the storage containers 2 in the article warehouse 4 . The controller 50 is preferably connected wirelessly to the storage vehicles 10, so that changes in the position of the storage containers 2 can be detected as a result of removal, storage and rearrangement. the

Control 50 is designed in such a way that at any time the current position of each

Storage container 2 in the article warehouse 4 or in the transport system 6 tracked. In addition, the controller 50 stores according to a further embodiment, the current number and the type of item 1 in the transport containers 2. When requesting a specific item 1 according to an order, the controller 50 can request that storage container 2, which

enables the most efficient execution of the order.

After the storage vehicle 10 has removed a desired storage container 2 or one requested according to an order, the storage container 2 is brought by the storage vehicle 10 to a transfer station 11 of the system 100 and made available there. The transfer station 11 is coupled to the transport system 6 in such a way that the storage vehicle 10 can reach the transfer station 11 directly via the rail system 7 and the storage containers 2

can unload at the transfer station 11.

As shown in Fig. 2, the transfer stations 11 are designed as shafts 12 connected to the rail system 7, in which the storage containers 2 can be lowered by storage vehicles 10, made available for removal of the items 1 and, after the items 1 have been removed, can be picked up again by a storage vehicle 10 . The storage containers 2 are then transported back up the shaft 12 by the storage vehicles 10 and stored in a stack 5 in a free position. Different embodiments of the provision of containers are known in the prior art, which are used as an alternative to the variant described for providing containers to the transfer station 11

be able.

At the transfer station 11, the articles 1 are transferred individually into transport containers 14 of an overhead conveyor system 15 according to the order. The transport containers 14 are in the form of transport bags 16 which are transported hanging in the overhead conveyor system 15 . As an alternative embodiment, the items 1 can also be transferred to a transport container 14 in the quantity requested according to the order in the transfer station 11, which is particularly advantageous for small items in particular. The transfer of the article 1 from the storage containers 2 in the transport container 14 can optionally manually by a

Picking person or done by machine by a picking robot.

The article 1 is transferred to the conveyor pockets 16 of the overhead conveyor system 15 in the order in which the storage containers 2 are made available at the transfer station 11 . The storage containers 2 can be requested by the controller 50 to fulfill an order or a group of orders in the most efficient manner, so that there are no waiting times for the storage containers 2 at the transfer stations 11 . For example, all storage containers 2, which are stored in top positions in stacks 5 quickly at one

Transfer station 11 are provided, while others lie deeper in stacks 5

Storage container 2 take a long time to provide. All items 1 required to fulfill an order or a group of orders can be transferred in any order to conveyor pockets 16 of the overhead conveyor system 15 and are then sorted into the required sequence 23, 23.1, 23.2, 23.3 in a subsequent step.

As shown in the plan view in FIG. 1 , the system 100 has a sorting system 17 for sorting the transport containers 14 . In the embodiment variant shown, the sorting system 17 is designed as a matrix sorter 18 which is integrated in the overhead conveyor system 15 . The conveyor pockets 16 can thus directly in the passage of the overhead conveyor system

15 pass the matrix sorter 18 and are thus sorted into a desired sequence.

For sorting the conveyor pockets 16 , the matrix sorter 18 has at least one sorting loop 19 , which is connected to the overhead conveyor system 15 via switches 20 . The sorting loop 19 can be used both to form a sequence 23 and as a buffer for the conveyor pockets 16 . Furthermore, the matrix sorter 18 has a number of points 21 on which the conveying pockets 16 can be guided over a number of parallel conveying tracks 22 . The points 21 can in turn be connected to the controller 50, which is programmed and designed so that the points 21 are switched alternately to a desired sequence 23.1, 23.2, 23.3 of articles 1 according to an order, in particular

a group of orders to produce in the conveyor pockets 16.

As further shown in FIG. 1, the system 100 also has picking stations 24.1, 24.2, 24.3, which are connected to the matrix sorter 18 via the overhead conveyor system 15. After the formation of a sequence 23.1, 23.2, 23.3 of articles 1 or conveyor bags 16 according to an order, the conveyor bags 16 are made available at the respective picking station 24.1, 24.2, 24.3. For this purpose, the picking stations 24.1, 24.2, 24.3 have corresponding unloading points 25, at which the articles 1 can be removed from the conveyor pockets 16 and transferred to the order containers 3. The transfer of the article 1 from the conveyor pockets 16 in the order container 3 can optionally manually by a

Picking person or done by machine by a picking robot.

Items 1 are made available at the first picking station 24.1 according to a first sequence 23.1 of a first order. At the second and third picking station 24.2, 24.3, according to Article 1, a second and third order 23.2, 23.3 are made available according to a second and third sequence. At the picking stations 24.1, 24.2, 24.3, the items 1 are then in the order in which they arrive, ie in the order of

respective sequence 23.1, 23.2, 23.3 picked into the respective order container 3.

The items 1 picked into the order containers 3 each reproduce the sequences 23.1, 23.2, 23.3. The sequence 23, in which the articles 1 in the conveyor pockets 16 are fed to the picking stations 24.1, 24.2, 24.3, can have, for example, the sequences 23.1, 23.2, 23.3 as partial sequences and reflect the individual orders in a group of orders. The partial sequences 23.1, 23.2, 23.3 in turn can reflect an order of the article 1 in the order container 3. The items 1 can be grouped, for example, in the order container 3 according to the sequence 23.1, 23.2, 23.3 according to size, color, variants or other properties. On the other hand, the article 1 in the order container 3 can also be present in an order in which the article 1 in one

Shop presented or lined up in a warehouse.

Finally, after picking the items 1, the order containers 3 can be

transported away to a goods issue system 27 by means of a conveyor belt 26 .

3 shows a system 101 according to a second embodiment variant of the invention. The system 101 has all the features of the previously described system 100, which is shown in FIGS. 1 and 2. Reference is therefore made to the above description of the figures

1 and 2 referenced.

The system 101 also has a second conveyor system 28 which is connected to a second article store 29 . The second item store 29 contains second items 30 which, due to their nature, cannot be stored in the storage containers 2 of the item store 4 . In the present embodiment, the second articles 30 are hangable articles such as clothes. The second articles 30 can then be fed directly to the overhead conveyor system 15 via the second conveyor 28 and sorted with the matrix sorter 18 just like the conveyor pockets 16 . The sequence 23 formed by the matrix sorter 18 can then also have second articles 30 in addition to the articles 1, which are transported in the conveyor pockets 16, in accordance with the order. Article 1 and second article 30 are then fed to the picking stations 24.1, 24.2, 24.3 according to the respective sequence 23.1, 23.2, 23.3 and there at the unloading station 25

Picking in the order container 3 are provided.

In an alternative embodiment, which was not shown in detail in the figures, the second article 30 can also be supplied in second storage containers to the transfer stations 11, where they, like the article 1 from the article warehouse to the

Conveyor bags 16 are passed and are made available at the matrix sorter 18.

As also shown in FIG. 3 , the system 101 also has a third article store 31 for the provision of third articles 32 . The third item warehouse is doing about a third

Conveyor 33 connected to the picking stations 24.1, 24.2, 24.3, so that in addition to the articles 1, 30 from the article warehouses 4, 29, which are provided in the form of the sequences 23.1, 23.2, 23.3, as well as the third article 32 for picking in the order container 3 are provided. The third articles 32 can be, for example, articles that cannot be transported via the transport container 10 and stored in the article warehouse 4, for example because the articles 32 are particularly large, particularly heavy and/or particularly bulky. By providing the third article 32 directly at the picking stations 24.1, 24.2, 24.3, they can be placed manually in the order container

to be picked.

The embodiment variant described above is also suitable, for example, for articles that can be stored in the article warehouse 4 and transported by means of the storage containers 4 and the conveyor pockets 16, but which are requested very seldom. Such very rarely requested articles are then usually stored at the bottom in the stacks 5 of the article warehouse 4 and therefore require a great deal of effort to relocate the storage containers 2 above, which limits the throughput of the article warehouse 4 . These rarely requested articles can thus be kept in other storage forms in the second or third warehouse 29, 31 and thus indirectly increase the throughput of the article warehouse 4

raise.
