  However, in such an article storage facility, when storage pallets that hold articles to be collected for the same shipping destination are distributed and stored in a plurality of automatic warehouses, individually in each automatic warehouse After collecting the items on the collection pallet, it is necessary to unload those collection pallets from the outlet and further collect the items on the multiple collection pallets. It was inefficient.

  The present invention has been made in view of the above circumstances, and the object thereof is to enable efficient picking work even when a plurality of types of articles to be picked are distributed and stored in a plurality of automatic warehouses. The object is to provide an article storage facility.

A first characteristic configuration of an article storage facility according to the present invention for solving the above-described problem is a storage shelf including a plurality of storage units arranged vertically and horizontally to store storage holders that hold articles to be picked. An automatic warehouse comprising a stacker crane that is movable in a moving space provided on the front side of the storage shelf, and the stacker crane has a collection holder for holding articles taken out from the storage holder A support unit for collecting goods that can be freely supported, and a picking device that takes out articles from the holding body for storage and transfers them to the holding body for collection, and stores the holding body for storage from outside A loading port for unloading the collection holding body to the outside is provided as a transfer target location of the stacker crane, and the collection holding body support portion is configured to connect the collection holding body to itself. Said Be one that is configured to support at freely state exchanged with the mouth,
A plurality of the automatic warehouses are provided. Among the plurality of automatic warehouses, one of a plurality of transfer target locations for a stacker crane in one automatic warehouse is used as a transfer source, and a stacker crane in another automatic warehouse is provided. There is an inter-shelf transport device that can transport the collection holder in one of a plurality of transfer target locations as a transport destination.

  That is, when a plurality of automatic warehouses are provided, when the storage holders that hold articles to be collected for the same shipping destination are distributed and stored in the plurality of automatic warehouses, the plurality of automatic warehouses Among them, one of a plurality of transfer target locations for a stacker crane in one automatic warehouse is used as a transfer source, and one of a plurality of transfer target locations for a stacker crane in another automatic warehouse is transferred. Since the collection holder can be transported first, after the transfer of the article from the storage holder to the collection holder in one automatic warehouse, the collection holder is completed. Is transferred to another automated warehouse, the collection holder is received by the stacker crane of the other automated warehouse, and the article is transferred from the storage holder to the collection holder in the other automated warehouse. Listed The picking operation can be performed in the same manner as before, and each time the collection work in each automatic warehouse unit is completed as before, the collection holding body is not released from the automatic warehouse and it is held for a single collection The collection can be continuously performed on the body at a plurality of automatic warehouses.

  And, if there is no inter-shelf transport device, when the storage holders that hold multiple types of articles to be collected are distributed and stored in multiple automatic warehouses, One holding body (for example, one of the collected collection bodies that have been delivered) is used to unload the holding bodies from the automatic warehouses, and to collect the articles collected on the collection holding bodies that have been delivered from the respective automatic warehouses. Work to be transferred to one or another holding body, etc., but according to the first feature configuration, collection is performed at a plurality of automatic warehouses for a single collection holding body. Therefore, it is not necessary to transfer as much as possible from a plurality of collection holding bodies to one collection holding body (for example, a shipping pallet), and the picking operation can be performed quickly.

  In short, according to the first characteristic configuration, it is possible to provide an article storage facility that can efficiently perform picking work even if a plurality of types of articles to be picked are distributed and stored in a plurality of automatic warehouses.

  According to a second characteristic configuration of the article storage facility according to the present invention, in addition to the first characteristic configuration, the plurality of automatic warehouses are provided adjacent to each other with the rear surfaces of the storage shelves facing each other. The conveyance source and the conveyance destination of the intermediate conveyance device are that the position in the height direction and the position in the traveling direction of the stacker crane are the same in each storage shelf of the adjacent automatic warehouse.

  That is, since the transport source and transport destination of the inter-shelf transport device are the same location in the height direction and the travel direction position of the stacker crane in each storage shelf of the adjacent automatic warehouse, the inter-shelf transport device The conveyance distance of the collection holder is short, and the collection holder can be quickly conveyed by the inter-shelf conveyance apparatus.

  In short, according to the second feature configuration, in addition to the operational effects of the first feature configuration, it is possible to provide an article storage facility that can perform a picking operation more quickly.

  According to a third characteristic configuration of the article storage facility according to the present invention, in addition to the first or the second characteristic configuration, the inter-shelf transfer device is supported by the collection holding body support portion. It is in the point comprised with the transfer apparatus which transfers a thing between self.

  That is, the collection holder supported by the collection holder support section can be transferred between the collection holder support section and the inter-shelf transport apparatus by the transfer device provided in the inter-shelf transport apparatus. Therefore, it is not necessary to provide a transfer device in the collection support body support for the transfer of the collection support body to the inter-shelf transport apparatus.

The collection support body support portion is provided on the stacker crane. Specifically, the collection support body support portion is provided on a lifting platform provided in the stacker crane. Since it is necessary to provide a transfer device for transferring the storage holder, the stacker crane (especially the lifting platform) will be enlarged if the collection holder support section is also provided with a transfer function. There is a fear.
By the way, in order to support the collection support body on the collection support body support section, the collection support body is artificially placed on the collection support body support section, or the collection support body support section On the other hand, the collection holder is placed by a transfer device (for example, a transfer fork) provided in the inter-shelf transport device or the warehousing conveyor.

  On the other hand, when the transfer device is provided in the inter-shelf transfer device as in the third characteristic configuration, the collection holder support section includes a mounting table that simply supports the collection holder. Only the stacker crane can be miniaturized.

  According to a fourth feature configuration of the article storage facility according to the present invention, in addition to any one of the first to third feature configurations, the storage holder has one type for a single storage holder. It is comprised in the form which hold | maintains articles | goods, The said stacker crane exists in the point comprised so that conveyance of the said holding | maintenance body for storage is possible with respect to the said inter-shelf conveyance apparatus.

  In other words, even if the collection holder can be transported between multiple automatic warehouses without leaving the automatic warehouse by the inter-shelf transport device, the picking target article is not duplicated for each automatic warehouse. If the storage is carried out at the location, the load will be concentrated on the automatic warehouse that stores the types of articles that often appear as the types of articles collected in the collection holder, and the picking operation at that location becomes a bottleneck. As a whole, the efficiency of the picking work may be reduced.

In such a case, in order to distribute the load among the respective automatic warehouses, it is necessary to store goods of a high frequency type as articles to be picked in a plurality of automatic warehouses.
However, when there is a shortage in an automatic warehouse where there is an article of the type to be stored redundantly as the picking operation is performed, the above-described load imbalance occurs, and the article is replenished to the automatic warehouse. Until then, there is a possibility that the efficiency of the picking work is reduced as described above.

  On the other hand, according to the fourth feature configuration, the stacker crane is configured to be able to transport the storage holder to the inter-shelf transport device, so that it is insufficient in one automatic warehouse and in the other automatic warehouse. It is possible to move storage holders that hold surplus types of articles from the other automatic warehouse to one automatic warehouse, reducing the uneven load between the automatic warehouses, making picking work more efficient Can be done automatically.
