Abstract

The invention provides an article storage device. The control system executes a shipment process, a replenishment process, a movement process, and a return process. The replenishment process is a process of transporting the 1 st article in the 2 nd storage (1B) from the 2 nd storage (1B) to the 1 st storage (1A) so that the 1 st article is stored in the 1 st storage (1A) in a state of being stored in a container when the number of the 1 st article in the 1 st storage (1A) is equal to or less than a threshold value of the number. The movement process is a process of conveying the 2 nd item, which is the picking object item in the 2 nd storage (1B), from the 2 nd storage (1B) to the 1 st storage (1A) so as to be stored in the 1 st storage (1A) in a state of being stored in a container. The returning process is a process of transferring the container containing the 2 nd article returned to the 1 st storage (1A) along with the completion of the discharging process from the 1 st storage (1A) to the 2 nd storage (1B).

Description

Article storage facility Technical Field The present invention relates to an article storage facility for storing articles that can be objects of a picking operation by supplying the articles to a picking operation area where the picking operation (picking) is performed. Background An example of such an article storage facility is disclosed in japanese patent application laid-open No. 2018-12586 (patent document 1). In the following description of the background art, reference numerals in patent document 1 are cited in parentheses. The article storage facility of patent document 1 includes a storage (1) for storing articles (B) such as corrugated cardboard boxes (cartioard boxes) and pallets (pallet) as articles (B) that can be objects of picking operations, and conveyors (C10 and C30) for supplying the articles (B) stored in the storage (1) to a picking operation area. In the picking work area, a picking robot (picking robot) (R) picks up a required number of cargoes from the object (B) and puts the cargoes into a collection box (collectioncase) (D). Disclosure of Invention Incidentally, in the above-described article storage facility, the storage capacity of the storage is generally designed so that all kinds of articles (in patent document 1, cargoes) that can be objects of a picking operation can be stored in the storage. Therefore, the size of the storage is liable to be large, and there is a possibility that the size of the article storage facility is large and the supply efficiency of the articles from the storage to the picking work area is lowered due to the large-scale storage. Therefore, a technique capable of suppressing an increase in the size of the article storage facility and a decrease in the supply efficiency of the articles to the picking work area is desired. The article storage facility of the present disclosure is provided with a1 st storage for storing the articles to be supplied to a picking operation area where the picking operation is performed and storing the articles that can be the object of the picking operation, the article storage facility being provided with a1 st storage for storing the articles that are the object to be supplied to the picking operation area, a2 nd storage for storing the articles that are the object to be supplied to the 1 st storage, a1 st transport means for transporting the articles between the picking operation area and the 1 st storage, a2 nd transport means for transporting the articles between the 1 st storage and the 2 nd storage, and a control system for controlling the 1 st storage, the 2 nd storage, the 1 st transport means and the 2 nd transport means, controlling the frequency of the articles, a frequency of the picking operation being the frequency of the picking operation being different, a1 st storage for storing the articles being the frequency of the order of the picking operation being set to be the order of the 1 st storage, and a1 st storage for picking operation being provided for the picking operation, and a2 nd storage for picking operation being provided for the picking operation being the article to be carried out between the 1 st storage and the 1 st storage, and a control system for picking operation being provided for picking operation, and a first storage for picking operation being carried out the articles is carried out by the first storage is provided for the first storage is provided, the replenishment process is a process of transporting the 1 st item in the 2 nd store from the 2 nd store to the 1 st store so that the 1 st item in the 2 nd store is stored in the 1 st store in a state of being stored in the container when the number of the 1 st item in the 1 st store is equal to or less than a predetermined number threshold value, and the transfer process is a process of transporting the 2 nd item in the 2 nd store from the 2 nd store to the 1 st store so that the 1 st item is stored in the 1 st store in a state of being stored in the container, and the transfer process is a process of transporting the 2 nd item in the 2 nd store from the 2 nd store to the 1 st store in response to the transfer process, wherein the 2 nd item in the 2 nd store is returned to the 1 st store by the transfer device. According to this configuration, since the container storing the article that can be the object of the picking operation can be stored in the 2 nd store having a larger storage capacity than the 1 st store in addition to the 1 st store, the storage capacity of the entire store including the 1 st store and the 2 nd store can be easily ensured to be large. Here, the 1 st storage is required to be installed in a manner that the 1 st conveyor can convey the containers between the picking operation area, whereas the 2 nd storage is not limited in this way, and is disposed, for example, by easily utilizing the empty space of the article storage facility, and the 2 nd storage is easy to ensure a higher degree of freedom in the installati
