Article storage facility, article storage method and article storage program

An article storage method to be executed by a control system in an article storage facility,

• the article storage facility comprising:
• a storage rack comprising a plurality of storage sections;
• a transport device configured to transport an article along a rack front surface, which is a front surface of the storage rack;
• and
• the control system configured to control the transport device, and
• the article storage method comprising a step of controlling the transport device so as to preferentially store a high frequency article at a first storage position and preferentially store a normal article at a normal storage position, and
• wherein:
• a rack depth direction is a direction orthogonal to the rack front surface, a rack front surface side is a side corresponding to the rack front surface in the rack depth direction, and a rack back surface side being-is a side opposite to the rack front surface side in the rack depth direction,
• the storage sections are each configured to store a plurality of the articles next to each other in the rack depth direction,
• the transport device comprises a transfer device configured to retrieve the articles from the storage sections and store the articles in the storage sections by moving the articles in the rack depth direction, from a position on the rack front surface side of the storage rack,
• the plurality of articles includes the high frequency article which is an article of an article type for which the retrieval frequency is a predetermined high frequency threshold value or more, and the normal article which is an article of an article type for which the retrieval frequency is less than the high frequency threshold value, based on information in which article type information and retrieval frequency information are associated with each other, the article type information indicating an article type for each of the articles, and the retrieval frequency information indicating a retrieval frequency for each of the article types, and
• each of the storage sections has a plurality of storage positions at which the articles are stored, the plurality of storage positions comprising at least one first storage position, which is a storage position closest to the rack front surface side, and at least one normal storage position, which is a storage position on the rack back surface side of the first storage position.

An article storage program for controlling an article storage facility,

• the article storage facility comprising:
• a storage rack comprising a plurality of storage sections;
• a transport device configured to transport an article along a rack front surface, which is a front surface of the storage rack;
• and
• a control system configured to control the transport device, and
• wherein:
• the article storage program causes a computer in the control system to realize a function of controlling the transport device so as to preferentially store a high frequency article at a first storage position and preferentially store a normal article at a normal storage position,
• a rack depth direction is a direction orthogonal to the rack front surface, a rack front surface side is a side corresponding to the rack front surface in the rack depth direction, and a rack back surface side is a side opposite to the rack front surface side in the rack depth direction,
• the storage sections are each configured to store a plurality of the articles next to each other in the rack depth direction,
• the transport device comprises a transfer device configured to retrieve the articles from the storage sections and store the articles in the storage sections by moving the articles in the rack depth direction, from a position on the rack front surface side of the storage rack,
• the plurality of articles includes the high frequency article which is an article of an article type for which the retrieval frequency is a predetermined high frequency threshold value or more, and the normal article which is an article of an article type for which the retrieval frequency is less than the high frequency threshold value, based on information in which article type information and retrieval frequency information are associated with each other, the article type information indicating an article type for each of the articles, and the retrieval frequency information indicating a retrieval frequency for each of the article types, and
• each of the storage sections has a plurality of storage positions at which the articles are stored, the plurality of storage positions including at least one first storage position, which is a storage position closest to the rack front surface side, and at least one normal storage position, which is a storage position on the rack back surface side of the first storage position.
