Multi-tier automatic warehouse

Abstract

Provided is a highly functional multi-tier automatic warehouse which has a high capacity and can suppress equipment cost and installation space. In the multi-tier automatic warehouse (10), two pairs of stacking racks (12L1, 12R1; 12L2, 12R2) are arranged in series instead of being parallel to each other, one lift device (16) is disposed between the two pairs of stacking racks, and loading and unloading can be carried out with respect to the two pairs of stacking racks by using the lift device only. This type of multi-tier automatic warehouse that has a tandem structure ensures a similar storage capacity as that of a conventional construction in which two pairs of stacking racks are arranged parallel to one other, and since it is not necessary to extend the multi-tier automatic warehouse (10) upward, the multi-tier automatic warehouse (10) can be applied to buildings having height limitations. In addition, since only the one lift device (16) is sufficient, the multi-tier automatic warehouse (10) comprises fewer devices than conventional constructions, and the multi-tier automatic warehouse can be constructed at less cost. Furthermore, the installation space of the multi-tier automatic warehouse (10) can be reduced.

Description

technical field [0001] The present invention relates to an automatic storage system, and more particularly to such an automatic storage system, wherein at least two pairs of multi-layer shelves are arranged in series. Background technique [0002] As a conventional automatic storage system, for example, the automatic storage system described in Japanese Patent Application Laid-Open No. Hei 5-21802 is known. Figure 9 The figure shows a conventional automatic storage system described in this document. This automatic storage system 1 includes at least a pair of left and right multi-level racks 3L, 3R each having a multi-level shelf 2 . On each level between the multi-storey racks 3L, 3R, a transfer shuttle car 4 capable of traveling in the horizontal direction is installed. Moving the load P up and down is performed by an elevator 6 provided at the same end of the multi-level racks 3L, 3R and having two elevator tables 5L, 5R. Further, transferring the load P to and receivin...

AI Technical Summary

Problems solved by technology

[0004] However, in the method of arranging the multi-level racks 3L, 3R in parallel, the number of devices including the automatic storage system 1 is simply scaled up, increasing the facility cost and requiring excessive space for installing the automatic storage system 1

[0005] The number of layers of multi-layer racks 3L and 3R can be increased to increase storage capacity, but if the building used for the system has height restrictions, the number of layers cannot be simply increased

In addition, the increase in the number of layers of multi-layer racks 3L and 3R increases the storage capacity, but prolongs the lifting stroke of the elevator 6, which in turn makes the movement of the elevator take more time, thus reducing the throughput capacity
