Patent attributes
An automatic warehouse includes multiple guided vehicles disposed at different heights along a rack and a storage shelf with a hoist in line with the rack. The storage shelf includes an intra-shelf conveyor that stores articles, and multiple shelf frames configured to vertically pass the transportation surface of the intra-shelf conveyor. The interval between the plurality of shelf frames may be varied. In parallel with the storage of articles using the intra-shelf conveyor, the shelf frames are caused to pass the transportation surface of the intra-shelf conveyor upward from below, and the articles are sequentially transferred from the intra-shelf conveyor onto the shelf frames. After the articles have been transferred to all the corresponding shelf frames, the guided vehicles store the articles on the shelf frames into the rack simultaneously.
