JPH038601A - Rack allocation method for automatic warehouse - Google Patents

Abstract

PURPOSE:To improve the management for racks and to reduce a warehousing and delivery time by ranking racks according to the crane operating time for warehousing, ranking goods according to the warehousing and delivery frequency, and making both to correspond to each other so as to allocate racks in an automatic warehouse using an automatic stacker crane. CONSTITUTION:Data for managing racks according to the order of crane operating time on every rack rank corresponding to the crane operating time is stored in a means 1 for making the crane operating time to correspond to the rack. Goods rank data calculated by the relationship between the warehousing and delivery frequency by the unit of goods and the number of racks on every rack rank is stored in a means 2 for managing the delivery frequency. A means 3 for giving correspondence to the means 1, 2 is adapted to allocate racks by making the data of both means 1, 2 correspond to each other. By this arrangement, the warehousing and delivery operating time can be reduced, and the management for racks can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a shelf allocation method for efficient staffing operations in an automated warehouse system using an autostaccato crane.

[Conventional technology]

In the conventional technology, empty shelves are managed using data, and shelves are simply assigned to the empty shelves of the data.

[Problem to be solved by the invention]

With the conventional allocation method, there is generally no problem with stocking empty shelves. However, when stocking the shelves, if the shelves are stocked in the order of empty shelves, as a result, the shelves cannot be managed in accordance with the frequency of stocking and retrieval, and moreover, there is a disadvantage that ineffective stocking and retrieval time is wasted.

SUMMARY OF THE INVENTION An object of the present invention is to provide a blank assignment method that eliminates the above-mentioned drawbacks, improves shelf management, and shortens warehouse loading and unloading times.

[Means to solve the problem]

The system of the present invention has a means for associating crane operation time with shelves, a means for managing the frequency of loading and unloading, and a means for associating the above two means.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. Referring to FIG. 1, one embodiment of the present invention includes means 1 for associating crane operation time with shelves, means 2 for managing the frequency of loading and unloading,
It is composed of means 3 for associating means 1 and 2.

The means 1 for associating crane operation time and shelves is constituted by a mask, and for each shelf rank according to the crane operation time,
Data for managing shelves in order of crane operation time is stored.

The storage/output frequency management means 2 is constituted by a mask, and stores data on product ranks calculated by correlating the storage/output frequency for each product with the number of types for each shelf rank.

The means 19 means 2 matching means 3 is the means 1 and the means 2.
Allocate shelves by associating them.

In FIG. 2(a), shelf 1. Shelf 2. ...Shelf A.

..., shelf 1. ..., shelf J, ..., l1m, ...
, In is the shelf number according to the crane operation time, and according to the operation time, shelf rank 1 = (shelf 1. shelf 2..., shelf A
).

..., shelf rank I = (shelf ■, shelf! +1. ...
, shelf J=1. shelf J)..., shelf rank n=(shelf m
, ..., shelf n-1. Shelf n) and shelf rank are grouped.

FIG. 2(b) is a mask image of the means 1 for associating crane operation time and shelves, and by managing all shelves for each shelf rank, maintenance of shelf ranks can be easily performed.

FIG. 3 shows a method for calculating the product rank for warehouse entry/output management in the means 2.

Arrange products in descending order of number of times they have been stocked (Ct ≧C2≧・
...≧C9) Cumulative number of warehousing times (Csu
The ratio of m = ΣCi) is 1 for each shelf rank for all species 1 in means 2 ('l'sum = ΣTi)
．． 1 The product rank R1+...IRII is set in association with the ratio of the numbers T11 T2 e...Th.

Figure 4 shows the search order of shelf ranks corresponding to each product rank at the time of stocking, and the table is managed on the mask.
Make maintenance easier.

In each shelf rank, a blank column is searched in order of shelf number and assignment is made.

〔Effect of the invention〕

By managing the crane operation time and the frequency of loading and unloading for each product using the empty shelves and allocation method described above, there is an effect that the loading and unloading operation time can be shortened.

[Brief explanation of drawings]

FIG. 1 is a block diagram showing an embodiment of the present invention, FIG. 2 is a diagram explaining the means for associating the crane operation time and shelves shown in FIG. 1, and FIG. 3 is the delivery frequency shown in FIG. 1. Management means 2
FIG. 4 is a diagram illustrating the association means 3 shown in FIG. 1. 1... Means for associating crane operation time with shelves,
2... Management means for frequency of entry and exit, 3...
The above-mentioned means for associating means 1 and 2.
