Abstract

PURPOSE:To reduce the number of controlling items of the master instruction tape in retrieving the supplementary storage shelf by figuring out the maximum allowable number of articles for supplementary storage so that the number is less than the maximum storing capacity of each shelf and searching for a storable shelf, based on the information of the number of articles in stock for each article or shelf. CONSTITUTION:Based on volume and weight of each article, processing section 4 calculates by each article the maximum number M of articles storable for each shelf in a warehouse 10. On the other hand, stock control table Q stores by article the number of articles in stock for each shelf D1 through Dn. When keyboard 2 inputs the name of article to be stored and the quantity, the processing section 4 accesses a void space control table P, checks the list of articles already stocked for each shelf D1 through Dn, and retrieves the shelf number that is storable. The thus retrieved shelf number is sent to a control section 8, and a input-allowing-message is displayed on a display section 1. According to this message, an article operator puts the article in the designated shelf. With this constitution, the number of controlling items of the master instruction tape can be reduced, shortening time for retrieval.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention is a storage shelf search method for searching for supplementary lighting storage shelves in an article storage room or the like.

(b) Prior art and problems In a system that manages the entry and exit of goods in a warehouse that has multiple storage shelves (hereinafter referred to as shelves), in addition to managing the number of stocks in each column, it is also necessary to manage the free space in each column. Requires. The maximum allowable capacity of a shelf is determined by the shelf's load limit (weight) and the volume of the shelf. Conventionally, when newly stocking an item, the vacancy of each column, that is, the remaining volume of each column, and the weight limit were totaled to determine whether or not the new item could be stored. In this conventional method, on the item mask that manages the items,
Two factors need to be managed: weight and volume.
After calculating these two factors, it is necessary to search for a shelf that satisfies both of these factors, which has the drawback of reducing search efficiency.

(c) Purpose of the invention The present invention has been made to solve the above-mentioned drawbacks.
The purpose is to provide a search method for inventory shelves that reduces the number of mask management items.

(d) Structure of the Invention The present invention comprises an input device, a processing device, and a plurality of shelves each having a predetermined permissible capacity determined by a weight limit and a volume, and is capable of handling a plurality of types having different volumes or weights. In a management system for storing items on the shelf, means for calculating a maximum allowable number of items to be stored that is less than the allowable capacity of the shelf for each of the plurality of types of items, and a means for calculating the maximum allowable number of items to be stored for each item. A management table for managing, an inventory table for managing the number of items in stock in each column, and a search means, and when the type and quantity of items to be stocked are input from the input device, the management table and the inventory are Using the management table,
This is an incoming shelf search method characterized by searching for a shelf where the article can be stored.

(e) Examples of the invention The present invention will be explained below with reference to the drawings. FIG. 1 is an explanatory diagram of the present invention, and FIG. 2 is a block diagram explaining one embodiment of the present invention, in which 1 is a display section, 2 is a keyboard, 3 is a control device, 4 is a processing section, and 5 is an operation section. board, 6 is the start button, 7 is the item,

Let us take as an example the case of warehousing management for a total of three types of articles, ``W'', ``W'', and ``C''. As shown in FIG. 1(a), the warehouse has a configuration in which a plurality of maximum storage capacity tzzr (Il[D) are arranged. In this embodiment, a storage unit U is defined, and the items A,
It is assumed that B and C and the maximum storage capacity tz of the shelf have the following relationship.

Article A...V, xw, = U Article B...
・・・・・・V2XW2=2U article C・・・・・・
...v, xw, = 4tJ Maximum storage capacity Z = 80 However, U is the storage capacity. In other words, one shelf can hold up to 8 items from item A, up to 4 items from item B, and This means that up to two items such as Article C can be accommodated.

The processing unit 4 in FIG.
is stored in file F.

In addition, in each column of the warehouse 10, items A to C are already listed in ~Dn).
The inventory management table Q is a table showing the inventory management status. For example, shelf number D1
1 each of articles A, B, and C are stored in , and only 2 articles A are stored in shelf number D, and 4 articles A and 1 article C are stored in shelf number Dn. are stored (the number in the column indicates the number of stored items). The processing unit 4 accesses the inventory management table Q, checks the empty status of each shelf number D, ~Dn, calculates the remaining capacity for each column for each item, and calculates this as the shelf number of the empty capacity management table Q. Since one each of articles A, B, and C 5 is stored in D1, the number of remaining articles that can be accommodated is calculated based on the maximum accommodation number data M of file F. Article A is U×1. Goods B is 2UX1
．． Also, article C stores 4UX4-each unit), so the remaining storage unit is .

8 (maximum capacity) - 7-1. Therefore, the shelf can accommodate only one more item A, and the processing unit 4 writes the number ``1'' in the item column A'' of the shelf in the free space management table P, and also writes the number ``1'' in the item column B of the shelf.
Write the number “0” in “〃” and “C”.

This calculation and writing process is actually performed immediately after storage.

Next, the case of warehousing will be explained. Operator is keyboard 2
, and input the name and quantity of the article to be stocked (for example, 2 pieces of article B). The processing unit 4 processes this input data (
When decoding the item B (2 pieces), the free space management table P
, and enter the item column “B” into shelf numbers D, to Dn.
to find a shelf number that allows for a quantity of 2 or more. In the embodiment, the shelf number Dt corresponds to this, so the processing unit 4 notifies the control unit 8 of the shelf number D, and also sends a message to the carrier 9 for 2 items of item B to be displayed, allowing large input of the display unit IK. When the start button 6 is pressed after loading the vehicle, the start signal ST from the control section 8 causes the carrier 9 to start.
starts moving, and article B (
2) are stored. In addition, in this storage, carrier 9 is shelf number D! After carrying out the items B, the items B (two pieces) may be loaded manually. carrier 9
When it returns to the starting position, the control section 8 issues the end signal E, so the processing section 8 corrects the number "1j" in the item column B' of the shelf number D of the inventory management table Q to the number "3".

Accordingly, the free space management table P is accessed, and the number "5" in the item column A of the shelf number D is rewritten to the number "1", and the numbers in the item columns B and C are rewritten to "0".

(f) Effects of the Invention As described above, the present invention has the advantage of being able to reduce the number of management items used during warehousing and shortening the search time.
