[Work process creation process executed by WMS 10]
Based on FIG. 4, the work process creation process executed by the WMS 10 will be described. FIG. 4 is a diagram showing a flowchart of work process creation processing executed by the WMS 10. As shown in FIG. Processing executed by each module described above will be described together with this processing. This work process creation process includes the acquisition process of the delivery destination information and product information (step S1), the process of allocating and determining the storage space for each delivery destination (step S2), and the work process creation process (step S3). are the details.

First, the shipping order acquisition module acquires a shipping order (delivery destination information and product information) (step S10). As described above, the delivery destination information may be personal information related to the delivery destination such as the delivery destination address, name, telephone number, etc., or may be a number or customer ID associated with the delivery destination information. As described above, the product information includes the name of the product, the product ID, the number of products, inventory information, and location information indicating the location where the product is picked. The shipping order acquisition module acquires one or a plurality of shipping orders by receiving a shipping order sent by a customer terminal (not shown) and receiving an input of a shipping order.
The list creation module creates a list of shipping orders based on the obtained shipping orders.
Through the process of step S10, the work support system 1 acquires the delivery destination information of the ordered product and the product information of the product to be shipped. In addition, the product information will include location information indicating the location from which the product is to be picked.

The picking order determination module determines the picking order (step S11). The picking order determination module determines the picking order based on the product ID, inventory information, and location information in the product information, in the order in which the locations where the products are stored are closest (location order). In other words, the determined picking order takes into consideration that the worker 2 moves less. In the picking process to be described later, the worker 2 performs the picking work according to the picking order determined by the picking order determining module.
Through the process of step S11, the work support system 1 determines the work order of the picking work in the order of the locations where the products are stored.

The bucket selection module selects a bucket (step S12). The bucket is an article for putting the products picked by the worker 2, and is a rectangular box with one side open. When this bucket is viewed from both sides of the opening, grid-like partitions are formed on the left, right, top and bottom, and the interior is divided by the partitioned frames. One section (frame) has a space for two pieces of picked products (boxes containing contact lenses). Also, the bucket 7 has an opening that enables photographing of all the commodities stored in the bucket 7 in a state in which all the commodities stored in the bucket 7 are stored in each category in a single photographing operation when an image is photographed by the process of step S32 to be described later.
It is preferable that a unique code or the like is assigned to each partitioned section. The code is a mark when the worker 2 stores the product, and is for individually identifying each section, and may be a color, a figure, a number, a symbol, a character, or a combination thereof. , preferably a number.
The bucket selection module selects bucket information (e.g., bucket ID, bucket type, specifically, size , division and coordinate information). The bucket selection module selects a bucket as a result of selecting bucket information. In the picking process, which will be described later, the worker 2 performs the picking work using the bucket corresponding to the bucket information selected by the bucket selection module.
In this embodiment, as shown in FIG. 9 to be described later, a description will be given using a bucket 7 that has 25 divisions (25 delivery destinations) of 5 vertical×5 horizontal and stores 50 commodities. The buckets 7 are numbered from 1 to 25 for each section.

The storage space allocation module determines storage space allocation (step S13). The storage space allocation module allocates a customer ID in the delivery destination information for each category of the selected bucket 7, and further allocates a product ID, quantity, and inventory information in the product information related to the delivery destination. The storage space allocation module allocates the storage space for the products picked by the worker 2 to each segment by allocating the customer ID, the product ID, the quantity and the inventory information to each segment from 1 to 25 of the bucket 7. will be assigned.

Through the processing of steps S12 and S13 described above, the work support system 1 divides one storage location into a plurality of sections as storage spaces, and assigns and determines these storage spaces for each delivery destination.

The work process creation module creates a work process (work ID) according to the order in which the locations where the products are stored are close (step S14). The work process creation module uses the product information acquired in the process of step S10 described above, the picking order determined in the process of step S11 described above, the bucket 7 selected in the process of step S12 described above, and the process of step S13 described above. A work process (work ID) is created based on the storage space allocated by the process. A work ID is an identifier associated with a work process. A work process is created for each work ID. For one work ID, bucket information of one bucket 7, acquired product information (one or a plurality of location information, product ID and quantity), and , and the allocated storage space.
Through the process of step S14, the work support system 1 generates a work ID corresponding to the work process. In addition, the work support system 1 creates a work process for picking a plurality of products for which a shipping order has been received, and determines the order of work for the picking work in the order that the locations where the products are stored are close to each other. Create a work process.
The work process creation module allows the worker 2 to store the product in the assigned category at one location, and the worker 2 to store the product in the assigned category at the next location. The order of places to pick up, the number of items to be picked, and the classification of items to be stored are created as a work process. At this time, the work process creation module determines the work order of the picking work in the order of the locations where the products are stored so that the moving distance for picking by the worker 2 is as short as possible, and follows this order. Create a work process.
As a result, the work support system 1 assists the worker 2 in sorting and picking products for a plurality of delivery destinations in one picking process.

[Example of work process]
The work process created by the work process creation module will be described with reference to FIG. FIG. 5 is a diagram schematically showing an example of a work process created by the work process creation module. In FIG. 5, the work process creation module creates a table in which work IDs, the determined picking order, the bucket information of the selected bucket 7, the acquired product information, and the allocated storage space are associated, Create work process. In this embodiment, work IDs, bucket IDs, locations, product IDs, and storage spaces are indicated.
The work ID is generated in association with this work process. The bucket ID indicates the bucket 7 used for picking work. The location indicates the inventory storage place of the product, and indicates the picking order in order from the top (worker 2 picks LA-01-01, LA-10-02, LA-07-03 in order). actual picking work). The product ID indicates the product to be picked. The storage space indicates the division number of the bucket 7 in which the picked products are stored.
One work ID is associated with one or more locations, and each location is associated with a product ID and a storage space. If there are other work IDs, each work ID has a similar configuration.

Returning to FIG. 4, the continuation of the work process creation process will be described.
The work process transmission module transmits the work process to the work support device 20 (step S15), and the work support device 20 receives this work process. The work support device 20 acquires the work process created by the WMS 10 by receiving this work process.

The above is the work process creation process.

[Picking process executed by work support device 20 and operator terminal 50]
The picking process executed by the work support device 20 and the worker terminal 50 will be described with reference to FIG. 6 . FIG. 6 is a diagram showing a flowchart of picking processing executed by the work support device 20 and the worker terminal 50. As shown in FIG. Processing executed by each module described above will be described together with this processing. This picking process is the details of the process (step S4) of displaying the product information and the storage space while classifying them as described above.

First, the work process creation transmission module transmits the work process received from the WMS 10 to the worker terminal 50 by the process of step S15 described above (step S20), and the work process reception module receives this work process (N=1 ) is received (step S21). When only one work ID is generated by the process of step S14, the work processes that are transmitted and received by these processes are only the work processes associated with one work ID. is generated, it is a work process (a plurality of work processes) associated with each work ID.
In the following description, it is assumed that N=1 (N is an integer equal to or greater than 1) and that the work ID "001" in FIG. 5 is transmitted and received as the work process.

The picking information display module displays the Nth picking information (step S22). The picking information display module displays the screen shown in FIG. 8 as the first picking information. At this time, the picking information display module displays, for each work process (work ID), the product information (product ID and number of picks) of the product to be picked by the worker 2 at a predetermined location (location) and the The storage space to be stored is displayed while characterizing the divisions (the divisions are displayed in such a way that they can be identified by color-coding or the like).
By the processing of step S22, the work support system 1 distinguishes between the product information of the product to be picked up by the worker 2 at a predetermined location and the storage space in which the product is to be stored for each work process. It will be displayed while

[Picking information display screen]
Picking information displayed by the picking information display module will be described with reference to FIG. FIG. 8 is a diagram schematically showing an example of picking information displayed by the picking information display module. 8, based on the received work process, the picking information display module displays work ID (001), location (LA-01-01), product ID (X02K3), number of picks (3), next location (L1- 10-02), which displays the categories (color-coded 4, 7 and 11) in which the picked items are stored.

The picking work actually performed by the worker 2 will be described.
Worker 2 browses the screen shown in FIG. 8, and performs the picking operation according to the displayed location, product ID, number of picks, next location, and storage category. Worker 2 moves to the location (LA-01-01) where the product to be picked is stored according to the displayed location. Worker 2 picks the product (X02K3) with the displayed product ID from among the products stored at this location according to the number of picks (3). The worker 2 stores the picked items in the categories (4, 7 and 11) of the bucket 7 that match the displayed categories. Worker 2 moves to the location (L1-10-02) where the next product is stored according to the displayed next location. The picking information display module receives an input operation to the "next" icon displayed on the picking information display screen, and obtains the product ID, the number of picks, and the classification of the product in the next location (L1-10-02). You may transition to the picking information display screen, or acquire your own position information from a GPS (Global Positioning System) or the like, refer to a database etc. stored in advance in association with the location and position information, and the current position will be displayed as follows. When it is determined that the worker 2 has moved to the position displayed in the next location when it matches or is close to the position information of the location (L1-10-02), and when the input operation to the "next" icon is accepted Similarly, the screen may be changed to the picking information display screen of the product ID, the number of picks, and the classification of the product in the next location (L1-10-02).
The worker 2 performs the picking work according to the picking information displayed on the picking information display screen until the picking work is completed at all locations.
In addition, the work support system 1 is operated by the operator 2 following the instructions of the displayed picking information, storing the displayed products in the bucket 7, and then pressing a completion button or the like (not shown). The inventory information in the picking space may be updated in the inventory management department that is not in stock. By updating the inventory information, it is possible to instruct replenishment as necessary so that there will be no shortage at the time of the next work ID. Also, an inspection instruction may be displayed on the worker terminal 50 when the worker 2 completes all the picking operations.

Returning to FIG. 6, the continuation of the picking process will be described.
The storage completion determination module determines whether or not storage is completed (step S23). The storage completion determination module determines whether or not the product storage is completed based on the picking information displayed by the picking information display module. The storage completion determination module executes this determination based on an input operation to "next" and whether or not the location information of the current location matches the location information of the next location. When the storage completion determination module determines that the storage is not completed (step S23 NO), that is, when the next input operation is not accepted or when the position information of the current position does not match the position information of the next location. , the picking information display module continues to display the picking information displayed by the process of step S22 described above.

On the other hand, if the storage completion determination module determines that storage has been completed (step S23 YES), that is, if a next input operation has been received or if the location information of the current location matches the location information of the next location, The picking completion determination module determines whether or not picking is completed at all locations (step S24). The picking completion determination module determines whether or not the product picking work has been completed at all the locations included in the received work ID. In this embodiment, the product picking work is completed at each of the locations "LA-01-01", "LA-10-02", and "LA-07-03" included in the work ID "001". determine whether it did. If the picking completion determination module determines that picking has not been completed at all locations (step S24 NO), that is, the locations "LA-01-01", "LA-10-02" and "LA-07-03" is not completed, the addition module adds 1 to N to make a new N (N=N+1) (step S25). The addition module treats the picking information next to the Nth picking information displayed by the process of step S22 described above as the (N+1)th picking information. When N=1, the new N becomes "2" (1+1=2) by the process of step S25.
The picking information display module returns to the process of step S22 described above, and newly displays the N+1th picking information (1+1 results in "2" in this embodiment).

The worker terminal 50 repeats the processing of steps S22 to S25 described above until all the received work processes are completed.
Note that a message prompting inspection work may be displayed on the worker terminal 50 when all of these work processes are completed.

On the other hand, if the picking completion determination module determines that picking has been completed at all locations (step S25 YES), that is, locations "LA-01-01", "LA-10-02" and "LA-07-03" , the picking completion information transmission module transmits the picking completion information to the work support device 20 (step S26), and the picking completion information reception module receives the picking completion information (step S26). S27).

The work ID transmission module transmits the work ID for which picking is completed to the inspection device 30 (step S28).

The above is the picking process.
When the main picking process is completed, the worker 2 moves the cart 4 with the bucket 7 placed thereon to the inspection area. The inspection device 30 performs an inspection process, which will be described later, on the bucket 7 .

[Inspection processing executed by inspection device 30]

Processing executed by each module described above will be described together with this processing.

The work ID reception module receives the work ID transmitted by the work support device 20 through the process of step S28 described above (step S30). The work ID received by this process is generated by the process of step S14 described above, and the picking work is completed by the picking process described above. As described above, this work ID includes the bucket information (bucket ID, size, division and coordinate information) of the bucket 7 used in the picking work and the product ID of each product stored in the storage space.
Note that the work ID may be obtained by inputting the work ID from the input unit (for example, code scanner or keyboard) of the inspection device 30 .

The coordinate master selection module selects a coordinate master from the bucket ID (step S31). The coordinate master selection module collates the coordinate information associated with the bucket ID included in the bucket information with the coordinate master stored in advance, and selects the coordinate master corresponding to this bucket ID. This pre-stored coordinate master is registered in advance for each bucket.

[Coordinate master]
The coordinate master will be described based on FIG. FIG. 10 is a diagram schematically showing an example of a coordinate master. The coordinate master in this embodiment has an origin 0 and has a total of 25 divisions of 5×5, and coordinates are assigned to each division.

Returning to FIG. 7, the continuation of the inspection process will be described.
The photographing module starts photographing the bucket 7 (step S32). The photographing module photographs the opening surface (upper surface) of the bucket 7 . At this time, the photographing module photographs all of the sections of the bucket 7 at once. As shown in FIG. 9, the photographing module photographs the entire opening surface of the bucket 7 at once by photographing the bucket 7 from above the opening surface of the bucket 7 .
Through the process of step S32, the work support system 1 acquires an image of all the products stored in one storage location, which are captured in a state in which they are stored in each storage space category. In addition, the storage space is provided with an opening through which the image can be acquired in one shot.

The scan position specifying module specifies the scan position based on the determination of the origin and the bucket ID (step S33). The scan position specifying module fixes the division (frame) of the bucket 7 at the specified position, uses it as a key for identifying the selected coordinate master, and determines the origin position of the virtual plane. As a result, the position of the photographed image of the bucket 7 can be recognized from the coordinate information, and is associated with the coordinate information of the bucket 7 in the work ID received by the process of step S30 described above.
The method of determining the positions of the compartments of the bucket 7 and the positions of the captured image compartments can be changed as appropriate. For example, there is a method of determining the origin and converting it into coordinate data, or a method of determining in advance the position where the image of the bucket 7 is to be captured and matching it with the selected coordinate master.

The photographing area identification module identifies the photographing area in which the division of the storage space is photographed by the coordinate master (step S34). The photographing area specifying module performs photographing of each section based on the coordinate information of each section of the coordinate master selected by the process of step S31 described above and the coordinate information of the scanning position specified by the process of step S33 described above. Identify areas. As shown in FIG. 9, the photographing area is specified for each section of each storage space.
Through the processing of step S34, the work support system 1 recognizes the origin of one storage location in the acquired image, and specifies the imaging region in which the division of the storage space in this image is captured.
Note that the photographing area specifying module attaches predetermined marks to the bucket 7 (for example, marks the four corners, the center, and the end), determines the size of the bucket 7, and specifies the photographing area. Also good. Since the size of each section of the bucket 7 is determined according to the size of the bucket, it is possible to specify the imaging area.

The identification label information acquisition module acquires identification label information for each section of each storage space (step S35). The identification label information is a product ID or the like stored in the product number label. The identification label information acquisition module acquires the stored identification label information in association with the coordinate information of each photographing area by reading the product number label attached to the box of the product photographed in each of the specified photographing areas. .
Through the process of step S35, the work support system 1 acquires the identification label information of the products in each storage space category.

The collation module collates the coordinates of each storage space segment with the identification label information (step S36). The collation module collates the product ID included in the identification label information associated with the coordinate information of each photographing area with the product ID of the product to be stored in each section in the received work ID.
By the process of step S36, the inspection device 30 checks the products stored in one storage location with the product information for each storage space based on the acquired identification label information, and inspects the products for each work ID. become.

The error determination module determines whether or not the collation is an error (step S37). If the error judgment module determines that the collation result is not an error (step S37 NO), that is, if it judges that the products to be stored in each category of the bucket 7 are stored, the completion display module performs picking and inspection. Display that the work has been completed. After that, the inspection device 30 terminates this process.

On the other hand, if the collation result is an error (step S37 YES), that is, if any or more of the categories of the bucket 7 contain incorrect products, the error display module indicates an error. display (step S38). The error display module displays incorrect product information as an error screen. For example, the error display module characterizes (colors, etc.) the erroneous product category in the image captured by the process of step S32 described above, and displays it. Alternatively, the error display module lists information about the incorrect product and displays the product ID of the incorrect product and the product ID of the correct product. The location where the correct product is stored may be displayed together with the product ID of the correct product.

[Error screen]
Error screens displayed by the error display module will be described with reference to FIGS. 11 and 12. FIG. FIG. 11 is a diagram schematically showing an example of an error screen that features and displays categories in which incorrect products are stored. FIG. 12 is a diagram schematically showing an example of a teleconference error display.
In FIG. 11, the error display module characterizes the divisions (10, 15, 12, 24) in which the incorrect products are stored based on the collation result by color coding, etc., and differentiates them from the divisions in which the correct products are stored. It is displayed as a display mode. In the present embodiment, sections 10 and 15 are telecoupling (the storage locations are reversed), section 12 is excessive, and section 24 is insufficient. The error display module indicates that the commodities stored in section 10 and the commodities stored in section 15 are telecoupled, and that the number of commodities stored in section 12 is excessive. , indicates that the number of products stored in section 24 is too small.
Although not shown, even if a product different from the product that should be stored in the category is stored, this category is similarly displayed in a display manner different from that of the category in which the correct product is stored. For erroneous products or products whose quantity does not match, the correct product location may be displayed, the correct quantity may be displayed, or the like.
According to the contents of this error screen, the operator 2 replaces the products in categories 10 and 15 indicated as telecoupling, reduces the number of products in category 12 indicated as excessive to an appropriate number, and replaces the products in category 24 indicated as insufficient. Increase the number of products to an appropriate number, etc.
Next, FIG. 12 will be described.
In FIG. 12, the error display module displays information about telecoupled products based on the collation result. In the present embodiment, product IDs "X02K3" and "X02L1" indicate the replacement and the number of products in section 10 and section 15, respectively.
The worker 2 replaces the commodities of the categories 10 and 15 indicated as telecoupling according to the contents of this error screen.

The above is the inspection processing.

As described above, according to the present invention, one delivery destination is assigned to one division to create product picking work instructions. Then, when the image of the item number label of the product is photographed, the coordinate information of the section in which the product is stored is acquired at the same time. As a result, the product information and the delivery destination information can be obtained in association with each other.
As a result, it is possible to sort and pick products for a plurality of delivery destinations in a single picking operation process, and to complete inspections for a plurality of delivery destinations by obtaining an image once. Since the conventional image inspection device inspects only one delivery destination, there is no need to determine where the product is arranged in the image, and there is no need to allocate the delivery destination for each category. Specifically, even if the arrangement of one product and another product is changed, it does not matter because the delivery destination is the same. In addition, as described in the background art of the present invention, when a plurality of buckets are placed on a single truck and compared with picking work for a plurality of delivery destinations, conventionally, inspection is performed for each bucket (one delivery destination However, according to the present invention, the inspection work can be performed by obtaining an image once, regardless of the number of delivery destinations.

According to the present invention, since each section of the bucket 7 = each frame = coordinate information = delivery destination, it is possible to obtain product information and delivery destination information at once, and collate products related to the delivery destination. It is possible to complete the inspection by batch photographing and data processing. Therefore, in response to shipping orders to multiple delivery destinations, the products can be sorted and picked, and batch inspection can be performed after sorting to multiple delivery destinations, greatly improving the efficiency of picking and inspection work. It will be possible to achieve
