Abstract

PROBLEM TO BE SOLVED: To automatically optimize the order of moving of commodities by preparing a prescribed location search pattern for each commodity. SOLUTION: A location search pattern is to listing a commodity moving origin list and a commodity moving target list in a preset and prescribed order according to the attribute data of a commodity mater 6A. When the commodity moving demand is inputted in a control terminal 1, a control part 5 prepares a written procedure 15 by collating the location search pattern. The procedure is such that an applicable commodity listed up in the top of the moving origin list and stored in the moving origin is stored in the moving target listed in the top of the moving target list, and when the applicable commodity listed in the top of the moving origin list and stored in the moving origin is all used up, the applicable commodity listed in the next thereto in the moving origin list and stored in the moving origin is stored in the moving target listed in the top of the moving target list in the order.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below using specific examples. In addition, the present invention is used when an arbitrary article is stored in a warehouse and warehouse management or warehouse management is performed. In the following description, an example in which various types of commodities are stored and managed in one warehouse will be described.

FIG. 1 is a schematic diagram of a warehouse management system suitable for implementing the present invention. This system is managed by a management terminal 1 such as a personal computer or a workstation. The management terminal 1 includes a keyboard 2, a mouse 3, a display 4, a control unit 5, and the like.
The control unit 5 includes a program for executing a program for controlling the warehouse management system, and the like. Display 4
Displays a screen for inputting instructions such as entry and exit of goods. An operator (not shown) uses the keyboard 2 and the mouse 3 to input a product movement instruction. Storage unit 6
Stores a product master 6A and a warehouse master 6B.

This system creates a procedure manual indicating a procedure for storing a product unloaded from a truck on which shelf in a warehouse, for example. In this example, the procedure manual is transmitted wirelessly to a location remote from the management terminal 1 and printed. For this purpose, the management terminal 1 is provided with a transmitter 7 and an antenna 8. An output unit 10 is provided at a location where the worker 9 is located. This output unit 10 is connected to the worker 9
And a terminal device attached to a forklift for transporting goods operated by an operator.

The output unit 10 includes a receiving antenna 11, a receiver 12, and a printer 13. The image of the procedure manual 15 generated by the control unit 5 is printed by the printer 13. The operator 9 transports a product (not shown) to the shelf while viewing the procedure manual 15.

The product master 6A stored in the storage unit 6
It is a database that stores information about products. Similarly, the warehouse master 6B stored in the storage unit 6 is a database that stores inventory information inside the warehouse. The product master 6A is data including all handled product names and their attribute data (properties). Attribute data includes
All information on each product, for example, product code, product name, standard, weight, information indicating product storage location, etc. are included. Further, for example, in the case of food, information such as whether or not the food is a frozen product and how to handle the food at the time of storage is also included.

Among such attribute data of a product, a data indicating a storage location of the product is called a location name. A warehouse for storing goods is provided with a number of shelves, and each of the shelves is given a location name using a number or a symbol in order from the end. The storage location map of the product viewed from the location where such shelves are arranged is called a physical location. The warehouse master 6B is data including, as attribute data, information indicating the physical location, as well as information such as the type and use of a product stored in each shelf.

By the way, when the operator instructs the movement of a product using the management terminal 1 as described above, specifically,
An instruction specifying a physical location, such as moving a product on a specific shelf to another specific shelf, can be input. The contents of this instruction are directly printed on the procedure manual 15 and used by the operator. However, it is not easy to input an instruction to move goods stored in several shelves to some other shelves according to a certain rule. Thus, the present invention enables not only a physical location to be specified, but also a logical location. A logical location is a grouping of storage locations based on the commonality of certain attribute data of stored products. That is, the physical locations are rearranged and grouped using the attribute data of the product as a key.

FIG. 2A is an explanatory diagram of a physical location, and FIG. 2B is an explanatory diagram of a logical location. The figure shows an example in which shelves in the warehouse 20 are grouped based on physical locations. This warehouse 20 is provided with a number of shelves. Each of these shelves has R11-R
13, R21 to R24, R31 to R34, R41 to R4
4, R91, R92, etc. Use this location name when storing products.

Zones Z1 to Z5 surrounded by broken-line frames are obtained by grouping the shelves in view of the arrangement of the shelves. These zones are provided based on, for example, the shape and arrangement of shelves, the functions of shelves, and the like. For example,
The group Z2 is a moving shelf group, and the group Z5 is a flat shelf group. When looking at each shelf in the warehouse and specifying a shelf according to the physical location, the operator can intuitively find the shelf. Therefore, the contents of the procedure manual given to the worker are best based on such a physical location.

FIG. 2B shows an example in which shelves in a warehouse are grouped based on logical locations. The logical zones RZ1 to RZ6 enclosed by broken lines are obtained by grouping the respective shelves as viewed from the attribute data of the commodities stored in the shelves. In merchandise management, it is often convenient to give an instruction to move a merchandise item in consideration of the type, nature, purpose, etc. of the merchandise item without knowing where the physical storage location of the merchandise item is. Therefore, it is effective for the operator who gives instructions to the operator to use this logical location.

FIG. 3 is an explanatory diagram of a method of utilizing a logical location. In the four shelves shown in (a), the first tier is designated for picking and the second to fourth tiers are designated as shelves for storing replenishment products. Conventionally, using the management terminal 1 shown in FIG. 1, for example, an instruction to “move refill products stored in the third tier to the picking shelf in the first tier.” From R to R4 ".

Therefore, when the same type of merchandise is stored in the second to fourth tiers, the number of merchandise stored in each shelf is checked, and the number of the first tier from each shelf is determined. You had to directly specify the procedure, such as moving to a shelf. For this purpose, the operator causes the display 4 of the management terminal 1 to display inventory information in the warehouse master 6B, that is, information indicating how many types of commodities are stored in each shelf and how much. It was necessary to consider a simple procedure and input the result.

On the other hand, if the logical locations as described above are used, the shelves of the second to fourth tiers are collectively set as a logical zone RZ1 in which the same product is stored, and "Shelves of products from RZ1 to RZ2 are stored." It is only necessary to specify “move”. When the movement of the product is designated using the logical zone, the computer takes out the products stored in the logical zone in a predetermined order and automatically prepares a procedure for moving the products to the destination. Create
Although the contents of the procedure manual finally presented to the worker are the same, the burden on the operator who operates the management terminal 1 is greatly reduced by this. The specific operation of creating a procedure manual by such a program will be described later in detail.

(B) In the warehouse, a predetermined number of DPS
(Digital picking system), an example in which a case shelf and a flat shelf are provided. In addition, the DPS is a shelf for displaying an instruction by digitally displaying a product to be picked (moved) on an attached display or the like. Each of the shelves is provided with a symbol R1 to R10 indicating a physical location according to a position in the warehouse.
Further, in this example, a logical location is set based on the type of each shelf. That is, four DPSs, four case shelves, and two flat shelves are respectively included in separate logical zones. In this case, by inputting an instruction such as “from the case shelf to the DPS” or “from the flat shelf to the case shelf” from the management terminal, an appropriate procedure for moving or refilling the product is created.

Further, for example, a case shelf in which a fixed number of products are packed in a box is stored in the case shelf, and a single product, that is, a piece product, is stored in the flat shelf. In this case, if a piece of goods is received, specify the logical zone of the flat shelf to store the product, and if a case product is received, specify the logical zone of the case shelf to store the product. An instruction such as storage may be input to the management terminal. For the stocktaking procedure and the like, the products can be distinguished using such a logical zone.

FIG. 3C shows an example in which storage places having partially commonality are set partially on four shelves having the same shape. These are collectively designated as the logical zone RZ1. In this way, it is possible to collectively move and manage products stored in these logical zones.

FIG. 4 is an explanatory diagram of a location search pattern according to the present invention. Next, a specific warehouse management method using the above logical locations will be described. Here, in this example, a case will be described in which an instruction 22 for replenishing a product from a replenishing shelf in a warehouse to a picking shelf is performed. At this time, the operator operates the management terminal 1 shown in FIG.
By using the keyboard 2 or the mouse 3, the user inputs an instruction to move a product in the logical zone in which the replenishing shelves are grouped to the logical zone RZ2 in which the picking shelves are grouped. For example, the number of replenishing shelves may be any number in the warehouse and may be distributed in any manner. The same applies to the picking shelf. Of course, either one of the replenishing shelf and the picking shelf may be singular.

When this instruction is input, the control unit 5 shown in FIG. 1 refers to the product master 23 shown in FIG. The product master 23 stores attribute data 25 for each product 24. This product is a product stored in a logical zone in which replenishment shelves are grouped. In order to automatically create a specific procedure when moving this product to a logical zone where picking shelves are grouped,
Prepare a location search pattern. This location search pattern is information for patterning the flow of goods in the warehouse for each product using the source and destination of the product as parameters.

More specifically, the structure is shown below FIG. In the movement source list 27 of the location movement source, the replenishment shelves included in the migration source logical zone are listed in a predetermined order. In this example, refill case shelf 1
No. 2, No. 3, No. 1 and flat shelf No. 1 are included in the logical zone in which the refill shelves are grouped. The source list 27 also includes information on the packaging of the product. On the other hand, the destination list 28 of the location destination
Lists the picking shelves included in the destination logical zone in a predetermined order. In this example,
DPS frontage No. 01, DPS frontage No. 25, shipping accessory shelf No. 1, shipping case shelf No. 1, No. 2, and No. 3 are included in the logical zone in which the picking shelves are grouped. The destination list 28 also includes information about the package as in the source list.

For example, when an instruction to designate a product on the replenishing shelf as a transfer source is input, a search is made in the product master 23 for a corresponding product having attribute data indicating that the product is stored in the replenishing shelf. And the list of all replenishment shelves in which those commodities are stored creates the above-mentioned source list. When an instruction to designate a picking shelf as a destination is input, the corresponding merchandise having attribute data indicating that the merchandise is already stored in the picking shelf is stored in the merchandise master 23.
Is extracted by searching, and all picking shelves in which those products are stored are listed up, whereby the destination list can be created. However, such lists are unique, for example, for each product and do not change frequently. In addition, as described later, in order to efficiently pick and move products, it is preferable to optimize the order of listing. Therefore, in the present invention, this location search pattern is created in advance for the type of work to be performed, and stored as product attribute data.

When the location search pattern is used and a product movement instruction is input using a logical location, a specific product movement procedure can be created from the viewpoint of the physical location. According to the procedure, first, an operation is started in which the merchandise stored at the source listed at the top of the source list of the location search pattern is stored at the destination listed at the top of the destination list. When there are no more items stored at the source that is listed at the top of the source list, select another source that is listed next to the source list in order, and delete the items stored at that source. At the destination listed at the top of the destination list. That is, in the example shown in the drawing, the operation is started by taking out the product from the replenishing case No. 1 and moving the product to the frontage No. 01 of the DPS. The first product is DPS frontage 01
Move to the task of moving to the turn.

Next, when the destinations listed at the top of the destination list are full, another destination listed next to the destination list is sequentially selected, and the goods are placed in the destination. store. That is, in the example shown in the figure, when the product is taken out from the replenishing case No. 2 and the product is moved to the DPS frontage 01, the DPS frontage 01 becomes full with the moved product, and the replenishing case 2 becomes full. The operation moves to move the second product to the frontage No. 25 of the DPS. Such a specific procedure is determined and output to the procedure manual 15 shown in FIG. Therefore, for example, in consideration of the route when transporting the goods by a forklift, the height from the floor when the products are sequentially stacked, and other various conditions,
If the order of listing is determined so as to maximize the work efficiency, the procedure can be optimized.

FIG. 5 is an explanatory diagram of a location search pattern selection operation. In the following, specifically, for example, when an instruction of “supplement of product W” is input to the management terminal 1 shown in FIG. 1, a procedure manual is created using the location search pattern, and the product is prepared according to the procedure manual. The operation of moving will be described.

For example, the location search pattern is 1
A maximum of six types can be prepared for one product according to the contents of the movement. This may be conveniently determined according to the size of the storage area of the product master for storing the attribute data of the product. For example, a pattern for a storage instruction, a pattern for a replenishment instruction, a pattern for picking, and the like are prepared. Therefore, when there is a storage instruction, a pattern for storage instruction is automatically selected, and when there is a picking instruction, a pattern for picking is automatically selected. However, it is also possible for the operator to arbitrarily designate a particularly desired pattern. Therefore, a picking pattern can be used for a product replenishment instruction.

In the example shown in the figure, a location search pattern 26 for instructing replenishment is selected to move the product W. In the transfer source list 27, three types of logical zones, LZ1, LZ3, and LZ5, are displayed in order.
Further, the destination list 28 displays locations A-1 to A-3 based on physical locations and logical zones LZ8 and LZ9 based on logical locations. Note that in the example shown in FIG.
7 and the destination list 28 also include information on the packaging of the product. In the case of this example, it is assumed that the package of the source product and the package of the destination product are the same, and a description thereof will be omitted.

As described above, when the instruction of "supplement of the product W" is input from the management terminal 1, the control unit 5 searches the attribute data of the product master 6A for the corresponding location search pattern of the corresponding product. And use it for preparing the procedure manual. The location search pattern 26 is "Product W
The “replenishment” pattern is expressed using a logical location and a physical location. As a result, it is possible to always create a procedure manual with constant contents for the same instruction.

FIG. 6 is an explanatory diagram of a specific method of moving a product printed on a procedure manual. When the above location search pattern 26 is used, the contents of the procedure manual are created as shown in FIG. First, the shelves X-1 and X-2 belonging to the logical zone LZ1 are displayed at the beginning of the movement source. The replenishment operation of the goods W is started from taking out the goods from these shelves. The number on the right side of each shelf indicates the number of products stored on each shelf. The shelf X-1 stores 800 commodities. The shelf X-2 stores 700 commodities. At the top of the destination list 28 shown in FIG.
-1 is displayed. The maximum number of stored products on the shelf A-1 is shown on the right side of the first location list in the destination list 28 in FIG. Shelf A-1 has a maximum of 1
000 items can be stored. As shown in FIG. 6, at first, no merchandise is stored in the shelf A-1. Therefore,
All 800 commodities are moved from shelf X-1 to shelf A-1 (step S1).

Next, a shelf for picking up a product is set on a shelf X.
Switch from -1 to shelf X-2. When 200 products are moved from the shelf X-2 to the shelf A-1, the shelf A-1 becomes full (step S2). This time, the shelf A-2 displayed on the destination list 28 is switched to the destination. Here shelf X-
The remaining 500 commodities are moved from 2 (Step S)
3). Shelf A-2 stores 100 commodities in advance, and when 500 commodities are moved from shelf X-2, the total becomes 600 commodities. Shelf A-2 has a maximum storage number of 100
Since there are no items, 400 items can still be stored. Therefore, 400 commodities are moved from the shelf X-5 belonging to the next logical zone LZ3 in the movement source list 27 (step S4).

The remaining 200 products on the shelf X-5 move to the shelf A-3 listed as the next location in the destination list 28 (step S5). Next, the source is switched to the shelf X-6. When 800 commodities are moved from the shelf X-6 to the shelf A-3, the shelf A-3 becomes full (step S6). The remaining 100 are destination list 2
8 to the shelf B-2 belonging to the logical zone LZ8. The shelf B-1 of the logical zone LZ8 has already stored 1000 commodities and is full. Therefore, the shelf B-2 is selected as the next destination of the product. 100 items are moved from shelf X-6 to shelf B-2 (step S).
7).

Next, the movement of the goods on the shelf X-9 in the logical zone LZ5 to the shelf B-2 is started. In this case, 70
Zero products are moved to the shelf B-2, and the shelf B-2 becomes full (step S8). After that, Logical Zone L
The goods are moved from Z5 to logical zone LZ9 (steps S9, S10, S11). Again, in this case,
In the same procedure as described above, the goods are moved from the shelves listed in the logical zone in order. Therefore, the replenishment operation of the products is performed in order from the shelf C-1 of the logical zone LZ9 until the products are full.

As described above, the operation of picking up the product from the source and storing it in the destination can be easily simulated by the program of the control unit 5 (FIG. 1) by using the location search pattern 26. When the result of the simulation is printed as shown in FIG. 6, the operator can mechanically replenish the product while viewing the procedure manual.

According to the procedure shown in FIG. 6 showing the details of the source shelf, the destination shelf, and the number of items to be moved, the operator can check the order of the items without error. Replenishment work can be performed. If such work is determined to be the most efficient in the procedure, the replenishment process is completed in the shortest time. In addition, since the contents of the procedure are very specific, the operator is not lost and errors can be prevented.
In addition, it is possible to store products with maximum efficiency in consideration of the storage capacity of each shelf. In addition, for example, the procedure manual is displayed on a display mounted on a forklift operated by an operator for transporting goods.

The above procedure manual can be updated in real time. For example, an operator moves a product from a certain source shelf to a destination shelf, and notifies the management terminal 1 of the state each time one section of work is completed. The management terminal updates the quantity of commodities stored in each shelf each time a report is received, executes the simulation each time, and generates a procedure manual for work to be performed thereafter. Alternatively, the part of the completed work in the initially displayed procedure manual may be erased or changed in color so that it can be distinguished. When the contents are displayed on the display, the operator can definitely select the operation to be performed next.

For example, there are various types of merchandise picking operations such as direct picking, wave picking, and stage picking. The direct picking is a method of picking products from a shelf while sorting the products by destination. In this case, a location search pattern in which shelves for each shipping destination are listed as destinations is used. Wave picking is also referred to as total picking, and is a method of picking a required quantity of products from a plurality of shelves at a shipping destination.
In this case, a location search pattern that lists the source shelves is used. Stage picking is a method in which picked products are transported to a place called a stage area and sorted while being picked for each shipping destination. Also in such a case, a location search pattern combining direct picking and wave picking is used with the source or destination as a stage.

According to the system of the present invention, in any case, it is possible to prepare a procedure manual for an efficient work instruction.

FIG. 7 is an explanatory diagram of an operation of updating attribute data of a product. The stock information of the warehouse master 6B shown in FIG. 1 also includes information on the physical location of each shelf in the warehouse. In the invention described below, the product master 6A and the warehouse master 6B are automatically linked during work such as moving the product. FIG. 7A illustrates an operation in which, for example, the forklift 31 stores a product 33 placed on a pallet 32 on a shelf indicated as A01. When such a storage operation is performed in response to a storage instruction, inventory status information of “new store” is set on the shelf indicated by A01. The stock status information is also a kind of the attribute data of the shelf in the warehouse master.

Here, the commodity 33 is stored on the shelf in response to the warehousing instruction, and when the operator is notified of this to the management terminal,
The attribute data of the product is automatically rewritten for the new store. Notification from the worker to the management terminal is verbal,
Various modes are possible, such as one by a keyboard operation of a portable terminal held by an operator, one by a barcode scanner, and the like. Further, when a product is put on a shelf, it is possible to update the stock information of the shelf according to the attribute of the product. Specifically, when the "stock status" of the location is "defective", when a product is put on the shelf, the attribute of the product is automatically rewritten to "defective". In addition, if the attribute of a product is "defective" and the product is put on any shelf, the inventory information on the shelf is rewritten to "defective".

For example, forklift 31 shown in FIG.
Is provided with a display for displaying a procedure manual having contents as shown in FIG. In this case, when the worker moves the product from the source shelf to the destination shelf and notifies the management terminal that the movement has been completed, at the same time, the attribute data of the product is, for example, as shown in FIG. ) Example,
It is updated to "for new stores."

In the example of (b), since the stock status of the location is "defective", the merchandise is stored and
The attribute data of the product is updated to the content “defective”. This is displayed on the display or the like of the forklift 31 shown in FIG. 7A, and the operator proceeds to the next operation while checking the contents. That is, if a product is moved in accordance with the product movement procedure manual, the attribute data of the product is automatically updated according to the movement, and efficient product management becomes possible. In the above description, the management of commodities stored in the warehouse has been described. However, the present invention is widely applied to a system that stores various articles in one or more warehouses and manages the movement thereof. Available.
