Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement of a picking system in a product distribution process, and particularly to an inspection device for checking the number of picked products.

(Conventional technology) At product distribution centers for supermarkets and chain stores, so-called picking operations are performed to assemble the required number of various products in response to requests from each store. The work was carried out by walking around the warehouse while looking at the order slip in hand.
This was done using only manual methods, such as collecting the necessary products in the necessary quantities. However, this method requires a high level of skill, as workers must remember the storage location of each product in the warehouse, and it is especially difficult to deal with the increasing variety and variety of products in recent years. On the other hand, each store is trying to reduce its inventory and there is a strong demand for speeding up this type of picking or delivery. .

In response to this situation, for example, Japanese Patent Application Laid-Open No. 57-137
: A picking system as shown in Publication No. 2.03 is being put into practical use. This system has one or more picking zones along the conveyor that transports containers for each destination, and each picking zone is equipped with product shelves with numerous pockets to store products by item. In addition, a number indicator is provided on each of the product shelves, and when a container for collection of products is conveyed to the picking zone by the conveyor, for example, for a store A, a number indicator A is displayed on the product shelf in that zone. This is configured to display the number of products to be picked this time for stores. Therefore, if a worker placed in the picking zone picks the indicated number of products whose number is displayed on the number display and collects them in the container, the container is discharged from the end of the conveyor. In some cases, products for the store A are collected in the requested number of items for all requested items. In this way, according to this pick-up system, picking work for a wide variety of items can be efficiently performed without requiring special skill on the part of the operator.

(Problems to be solved by the invention) By the way, even in the above picking system,
The work of taking out the products from the pockets of the product shelf and transporting them into the container is done manually, so for example, when taking out the products from the pockets, there are cases where the number of products is not taken out according to the number displayed on the number display, or when the products are taken out and placed in the container. Sometimes I drop something without realizing it before I put it in.
There may be cases where the displayed number of products for each item is not correctly collected into the container. Therefore, in this type of picking system, an inspection worker placed at the end of the conveyor performs inspection work to check the number of products in the container after all items have been picked, while comparing it with the order slip, etc. is necessary. However, this work is extremely troublesome and takes a long time, and the speed of the picking work achieved by employing a picking system for this work is impaired.

The present invention deals with the above-mentioned conventional situation, separately ensures the accuracy of the number of items to be collected, eliminates the need for inspection work at the end of the conveyor, and thereby speeds up this type of picking work. With the goal.

It has a product shelf where products are stored for each item and a number display installed on the product shelf, and a worker placed in each picking zone can display the products in each pocket on the number display. In a picking system configured to pick only the number of products to be picked and collect the products into a container on the transport means, the total number of products to be picked in the picking zone is located near the location where the products are to be collected into the container on the picking zone. The present invention is characterized by comprising a total number display device that displays the total number of pieces.

In addition, in the picking system similar to the first invention, the inspection device according to the second invention displays the number of each item of each product to be picked in the picking zone near the position where the products are collected into the container in the picking zone. It is characterized by being equipped with a number display device for each item. In that case, the item-by-item quantity display device may display only the number of items picked from each pocket each time when a picking completion key provided in each pocket of the product shelf is turned on. In addition, the number of picked items for all items to be picked in the picking zone may be displayed simultaneously or continuously together with the item name or item code, and in the latter case, the item name or item code display function may be Alternatively, or in addition to this function, a barcode scanner for reading barcodes attached to products may be provided, and the number of picked items whose barcodes are read by the scanner may be displayed.

(Function) According to the above configuration, in the first invention, the total number of products to be picked in the picking zone is displayed on the total number display device placed near the location where the products are collected into the container in the picking zone. Therefore, once the workers in the zone have finished collecting all the products into the containers, they can compare the number of products they have collected with the number displayed on the display device, thereby avoiding picking mistakes. It becomes possible to confirm the presence or absence. Since the inspection is performed in the picking zone in this manner, there is no need for troublesome and time-consuming inspection work such as verification with the order slip at the terminal end of the container conveyance means.

Furthermore, according to the second aspect of the invention, the number of items picked for each item is displayed on the item-by-item number display device placed near the location where the items are collected into the container. It becomes possible to check each time, which further improves inspection accuracy. In this case, if the above-mentioned item number display device is configured to display only the number of items in each pocket by turning on a picking completion key provided in each pocket on the product shelf, it is possible to The number of products can be confirmed at the time of putting them into the container, which is particularly effective when transporting products one by one from pockets into the container.

Furthermore, if the item-by-item quantity display device is configured to display the item name or item code and the number of pieces to be picked for all items to be picked in the picking zone all at once or continuously, When picking is complete, you can check the number of pieces picked for each item. In that case, if you are equipped with a barcode scanner, you can easily pick each item without having to remember the name or code of each item. The number can be confirmed.

Next, the structure and operation of the embodiment of the first invention will be explained. In this embodiment, the inspection quantity display device 5 is configured to display the products to be picked in the picking zone, as shown in FIG. A total number display section 17 that digitally displays the total number of items, and an inspection completion key 18 are provided.

This embodiment operates as follows according to the flowcharts shown in FIGS. 5-8.

First, the picking data storage device (hereinafter simply referred to as data storage device) 15 operates according to the flowchart shown in FIG. 5 at the start of work.

That is, this data storage device 15 first performs step S,
, and waits for an execution command from the work control device 7 instructing the start of work in S2. Then, the container supply position 6 shown in FIG.
For example, when a worker places a drug container a for a store A product on the starting end 1a of the conveyor 1 and performs an operation to start picking work using the work control device 7, the data storage device 15 An execution command indicating this is received from the work control device 7, and in step S3 each picking zone 2 is

Next, the data storage device 15 stores the first stop position 1 of the conveyor 1! The number of items to be picked is indicated on the number indicators 11...11 of each pocket 10...10 in the first and sixth picking zones 2+ and 26 product shelves 4...4 provided on both sides of the Send display command. In this case, step S4. According to S, first, the picking number data of the item to be picked is sequentially transmitted to the number display 11 of the pocket 10 in which the item to be picked this time is stored in the first picking zone 21, and the transmitted number data is transmitted each time. are input into the register for the first picking zone 21 and added sequentially. Then, the data storage device 15 selects the first picking zone 2 in step S6.
When it is determined that the number data has been sent to all the corresponding number display units 11...11 of 1, step S is executed, and the total number data obtained by adding up the number of picked items of each item added in the above register is obtained. It is transmitted as a total number display command to the inspection number display device 5 in the first picking zone 21. Furthermore, once the transmission of each picking number data and the total number data to the first picking zone 21 is completed in this way, or in parallel with this transmission, step 8 is performed.
4 to S7, the same data is transmitted to the number display device 11 of each pocket 10 . . . 10 in the sixth picking zone 26 and the number display device 5 for inspection.

In this way, the first one closest to the starting end 1a of the conveyor 1. 6th picking zone 2. ．． 2. When the transmission of data to the zone 21.26 is completed, the picking operation will start in these zones 21.26, but at this time, the number indicators 11...11 of each pocket 10...1o are It operates according to the flowchart shown in the figure.

That is, each number display 11 performs a predetermined initialization at step S, and then waits for a command to display the number of picked items from the data storage device 15 (see step S4 in FIG. 5) at steps S12 and S13. As for the number display 11 of the pocket 10 in which the item to be picked this time is stored, by receiving the number display command, the picking instruction lamp 13 is turned on in step 314, and the data storage device 15 is displayed on the display unit 12.

If the message from 1 is a message other than the picking completion message, step S23 is changed to step S23.
27 and performs processing according to the message.

Further, when the message whose reception is confirmed in step S21 is a message from a source other than the number display 11, steps 828 to S32 are executed, but this operation will be described later.

Furthermore, the inspection quantity display device 5 operates as follows according to the flowchart of FIG.

First, after predetermined initialization is performed in step S41, a total number display command from the data storage device 15 (see step S7 in FIG. 5) is awaited in step S42+843. When this command is received, the total number sent from the data storage device 15 is displayed on the total number display unit 17 shown in FIG. 4 in step S44, and the inspection completion flag is reset in step S45. Here, if the command received in step S42 is a command other than the total number display command, processing in accordance with the command is performed in step S46.

Next, this inspection quantity display device 5 performs step S47.
In step 3, it is determined whether the inspection completion key 18 shown in FIG.
4g, S49 waits for a collection completion message from the data storage device 15 (see step S26 in FIG. 7). Then, if this message is received, step S50
．． In step 35), the inspection completion flag is set, and the total number display on the total number display section 17 is made to blink.

As a result, the first. The workers S and B in the sixth picking zone 21 and 26 can confirm the completion of the picking work in the picking zone, and also check the flashing total number display on the inspection number display device 5 and the number of pieces in the container a. By comparing the total number of products that the user has put in, it is possible to check whether there has been a picking error. Then, if there is no picking mistake and the number of items collected and the number displayed are two, the inspection completion key 18 of the number display device 5 for inspection is turned on. Step 5 executes steps S47 to S85□ to S54, and after confirming that the inspection completion flag is set, erases the display on the total number display section 17 and sends an inspection completion message to the data storage device 15. Send. Here, if the inspection completion key is turned on before receiving the collection completion message from the data storage device 15, the inspection completion flag remains reset.
Therefore, step S53 + 854 is not executed,
Further, if the message received in step 84g is not a drug completion message, processing according to the message is performed in step S55, and if the picking operation is interrupted for this processing, step SS6 to step S
The process returns to step 42 and executes the above control again.

Then, when the inspection completion key 18 is turned on and an inspection completion message (see step S54 in FIG. 8) is transmitted from the inspection quantity display device 5 to the data storage device R15, the data storage device 15 From step S22 in the flowchart of the figure, through step 32g+329, and step S. and transmits a message to the work control device 7 indicating that the work in the picking zone 21 or 26 is completed.

In this case, if the message received in step S21 is not from either the piece count display 11 or the inspection piece count display 15, the inspection is performed in step SSI even if the message is from the inspection piece count display 15. If the message is other than the completion message, processing is performed in accordance with each message in step S32, but in particular, the total number displayed from the inspection number display device 15 and the number of collected items in container a. When a message indicating a mismatch is received, for example, additional picking of the corresponding product or removal from container a is performed in order to make the message match.

As described above, the picking work and the inspection work for the container a of the product in the first and sixth picking zones 2s and 2c for the store A located at the first stop position 11 of the conveyor 1 are completed. Then, the worker at the container supply position 6 receives a work completion message (step S26 in FIG. 7) sent from the data storage device 15 to the work control device 7.
After confirming the completion of the work in both zones, the worker places, for example, the next container a for collecting products for store B on the starting end 1a of the conveyor 1, and also controls the work. The device W7 is used to start the next picking operation. As a result, the container a for store A located at the first stop position 11 of the conveyor 1 is moved to the second stop position 12, and the starting end 1
Container a for store B placed at a is at the first stop position 1

The operation is as follows according to the flowchart shown in FIG.

First, the data storage device 15 performs step T1. of the flowchart of FIG. At T2, an execution command to start the work is waited for from the work control device 7, and when this command is received, the picking zone 2 is started at steps T, T4.
, 2, a number display command is sent to the number display devices 11...11 of the pockets 10...10 in which the products to be picked this time are stored, along with the data on the number of items to be picked.

On the other hand, the number display 11 that received the above number display command
. . 11 performs operations such as displaying the number of pieces on the display unit 12 and lighting the picking instruction lamp 13 according to steps T11 to T07 of the flowchart shown in FIG. 11, but these operations are similar to those in the embodiment of the first invention. The operation is similar to that in , and the picking operation is performed according to the operation.

Also, during this picking operation, the data storage device 15 operates according to the flowchart in FIG. 12, but in this embodiment, according to steps T21 to T23,
When receiving a picking completion message from the piece count display 11 by turning on the picking completion key 14,
At the same time as storing the status indicating completion of the picking work for the number display 11 in step T24,
Step T2. Then, an item-by-item number display command for the item corresponding to the number display 11 that received the picking completion message is transmitted to the inspection number display device 5'.

At this time, the inspection piece count display device 5' receives the item-by-item count display command, executes steps T and 4 through steps T41 to T43 in the flowchart of FIG.
Item code display section 19 and item-specific number display section 20 shown in the figure
Displays the item code of the item and the number of pieces picked for that item. Thereby, when the worker puts the product picked from the pocket 10 into the container a, the worker can compare the number of the product with the number displayed on the inspection number display device 5'. It becomes possible to check whether there is a picking mistake. Here, when picking multiple items at the same time, the picking completion keys 14 of the multiple number displays 11...11...
・When 14 is turned on, the item codes and quantities of these multiple items are displayed on the inspection quantity display device 5'.
In this case, the worker must check the number of items for each item.

When the inspection item number display device 5' receives the inspection completion display command, it executes steps T'io from step T49 in the flowchart of FIG. 13, and displays a display indicating the completion of the inspection work for all items. conduct.

As in the embodiment of the first invention, the above operations are sequentially repeated for each picking zone 21 to 210, so that when the container a is discharged from the terminal end 1b of the conveyor 1, the inside of the container a is This means that all items to be picked are always collected correctly.

In this embodiment, when an item is picked from one or more pockets 10, the number of items is displayed on the inspection item number display device 5' for only that item. Therefore, according to this embodiment, each time one item or multiple items picked at the same time are put into container a, the item is inspected. By displaying the number of all items, it becomes possible to inspect all the items at once after collecting them in container a. In that case, if the number of items to be picked is large and the number of items cannot be displayed all at once on the inspection piece count display device 5', for example, the item for which the inspection completion key 21...21 has been turned on may be displayed. All items may be displayed continuously, such as by erasing the item and then displaying the item code and number of items that have not been displayed.

In addition, in this second invention, the inspection quantity display bag 25
' Since the number of pieces is displayed for each item, high inspection accuracy can be obtained, but on the other hand, it is necessary to check which item the number of pieces corresponds to by the item code that is displayed at the same time. Confirmation becomes troublesome.

For this purpose, instead of displaying the item code, the product name may be displayed in characters, or the inspection quantity display device 5' may be equipped with a barcode scanner, and the barcode scanner may be used to display the product name. When a barcode is read, the number of items is displayed only for that item or the display is made to blink, thereby making it unnecessary to check the item code.

Furthermore, the inspection quantity display device 5' is configured with a CRT or the like to display the quantity of all items, and each time the picking completion key 14 for each item is turned on, the item name or item name of the item is displayed. It is also possible to make the code, number, etc. blink on the CRT screen, or when displaying the number of all product numbers in this way, when the inspection is completed and the inspection completion keys 21...21 are turned off.
If the display is configured to sequentially erase the items that have been subjected to the N operation, the remaining items to be picked and their number will be displayed during the picking operation, allowing the operator to know this in advance. This makes it possible to improve subsequent work efficiency.

In addition, No. 1 of this application. The second invention is not limited to those shown in the above embodiments, and various embodiments other than these embodiments can be adopted.

For example, in a small-scale system, product shelves can be arranged in parallel with the conveyor 1, and all of these can be set as one picking zone.

In this case as well, since the picked products are inspected when they are collected into containers, there is no need for troublesome and time-consuming inspection work using order slips and the like at the container discharge position.

Furthermore, in each of the above embodiments, the pocket 10...1
A number display 11...11 is provided for each pocket 10...11, but instead of this, one number display 11 is provided for each pocket 10...10, and each pocket 10...10 is provided with a number display 11 for each pocket 10...10. It is also possible to provide an instruction lamp 13 and a picking completion key 14 to cause the number display 11 to sequentially display the number of items picked for a plurality of items.

Furthermore, regarding the second invention, when the number of items to be picked at the same time is extremely small, only one inspection completion key 21 is provided in the inspection quantity display device 5', and by the operation of the inspection completion key 21, the number of items to be picked at the same time is displayed. It is also possible to perform processing. In addition, when the number of items to be picked in one picking zone is small, the total number is displayed in a specific display column of the inspection number display device 5', and this total number display and the number of items are It may also be possible to switch between the display mode and the number display for each item when there are many items.

(Effects of the Invention) As described above, according to the present invention, a picking zone is provided along the transport means for transporting the containers at each destination, and according to the display on the number display provided on the product shelf in the picking zone, In a picking system configured to pick products stored in each pocket of a product shelf, the total number of products for inspection is displayed in the above-mentioned picking zone, indicating the total number of products or the number of each item to be picked in that zone. Since a display device or a number display device for each item is provided, the number of products to be picked from each pocket or the number of products to be collected into a container is determined in the picking zone by the worker who picked the products. This eliminates the need for laborious and time-consuming inspection work using order slips, etc. at the container discharge position at the end of the above-mentioned transport means, which was previously required, and allows for product picking using this type of picking system. This will further speed up the process.
