Abstract

An automated warehouse system may require less space than conventional warehouse systems. The automated warehouse system is configured so that loads are stored in storage areas formed by vertically extending support pillars and horizontally extending beams. The loads are loaded into the storage areas, and the loads are unloaded from storage areas. The automated warehouse system comprises: vertical guide rails disposed on the support pillars; horizontal guide rails disposed on the beams; and a movable platform having a frame body and guide rollers, at least part of the frame body having the same rectangular shape as a shape of at least part of at least one of the storage areas and having vertical frame members and horizontal frame members, the guide rollers being disposed on the vertical frame members and engaging the vertical guide rails or disposed on the horizontal frame members and engaging the horizontal guide rails.

First claim

What is claimed is:

1. An automated warehouse system that stores loads in a plurality of storage areas formed from a plurality of support pillars that extend in the vertical direction and a plurality of beams that extend in the horizontal direction, that transfers the loads to the plurality of storage areas, and that transfers the loads from the plurality of storage areas, the system comprising:
a vertical guide rail that is disposed on a support pillar of the plurality of support pillars;
a horizontal guide rail that is disposed on a beam of the plurality of beams; and
a movable platform having a frame body that has a vertical frame and a horizontal frame, at least part of the frame body having a rectangular shape that is the same as a shape of at least part of at least one of said storage areas, and a guide roller that engages the vertical guide rail that is disposed adjacent the vertical frame or the horizontal guide rail that is disposed adjacent the horizontal frame, the guide roller being movable with respect to the movable platform in a direction that is perpendicular to the vertical guide rail and the horizontal guide rail.

2. The automated warehouse system as set forth in claim 1 , wherein:
the movable platform has a picker configured to slide the loads to transfer the loads from the movable platform into the storage areas, and to slide the loads to transfer the loads out of the storage areas into the movable platform.

3. The automated warehouse system as set forth in claim 1 , wherein:
the guide roller is disposed at a corner portion of the frame body; and
when the loads are transferred into or transferred out of the movable platform, the guide roller is moved into contact with the vertical guide rail or the horizontal guide rail.

4. The automated warehouse system as set forth in claim 1 , further comprising:
a locking device configured to lock the horizontal guide rail and the movable platform together when transferring the loads into or transferring the loads out of the movable platform.

5. The automated warehouse system as set forth in claim 1 , wherein:
the guide roller is movable along an edge of the frame body in the horizontal direction to a corner portion of the frame body; and
when the movable platform is moved in the horizontal direction to transfer the loads into or out of the movable platform, the guide roller is located at a center region of the edge of the frame body in the horizontal direction, and when the movable platform is moved in the vertical direction to transfer the loads into or out of the movable platform, the guide roller is located at the corner portion of the frame body.

6. The automated warehouse system as set forth in claim 5 , wherein:
the guide roller includes a first guide roller and a second guide roller, where a movement distance of the first guide roller from the center region of the edge of the frame body to the corner portion of the frame body and a movement distance of the second guide roller from a center region of another edge of the frame body in the horizontal direction to a corner portion of the frame body are different.

7. The automated warehouse system as set forth in claim 1 , wherein:
the movable platform is disposed between a first storage shelf that includes a plurality of storage areas, and a second storage shelf that includes a plurality of storage areas and that is disposed so as to face the first storage shelf;
the guide roller includes a first guide roller and a second guide roller; and
the first guide roller is disposed on a first side of the movable platform that faces the first storage shelf and the second guide roller is disposed on a second side of the movable platform that faces the second storage shelf.

8. The automated warehouse system as set forth in claim 7 , further comprising another movable platform, wherein:
the other movable platform is disposed between a third storage shelf that includes a third plurality of storage areas, and a fourth storage shelf that includes a fourth plurality of storage areas and that is disposed so as to face the third storage shelf; and
the second storage shelf adjoins the third storage shelf.

9. The automated warehouse system as set forth in claim 1 , wherein:
the frame body of the movable platform corresponds to a plurality of adjoining storage areas.

10. An automated warehouse system that stores loads in a plurality of storage areas formed from a plurality of support pillars that extend in the vertical direction and a plurality of beams that extend in the horizontal direction, that transfers the loads to the plurality of storage areas, and that transfers the loads from the plurality of storage areas, the system comprising:
a vertical guide rail that is disposed on a support pillar of the plurality of support pillars;
a horizontal guide rail that is disposed on a beam of the plurality of beams; and
a movable platform having a frame body that has a vertical frame and a horizontal frame, at least part of the frame body having a rectangular shape that is the same as a shape of at least part of at least one of said storage areas, and a guide roller that engages the vertical guide rail that is disposed adjacent the vertical frame or the horizontal guide rail that is disposed adjacent the horizontal frame,
wherein the guide roller is movable along an edge of the frame body in the horizontal direction to a corner portion of the frame body; and
wherein, when the movable platform is moved in the horizontal direction to transfer the loads into or out of the movable platform, the guide roller is located at a center region of the edge of the frame body in the horizontal direction, and when the movable platform is moved in the vertical direction to transfer the loads into or out of the movable platform, the guide roller is located at the corner portion of the frame body.

11. The automated warehouse system as set forth in claim 10 , wherein:
the movable platform has a picker configured to slide the loads to transfer the loads from the movable platform into the storage areas, and to slide the loads to transfer the loads out of the storage areas into the movable platform.

12. The automated warehouse system as set forth in claim 10 , wherein:
the guide roller is disposed at a corner portion of the frame body, and is movable in a direction that is perpendicular to the vertical guide rail and the horizontal guide rail; and
when the loads are transferred into or transferred out of the movable platform, the guide roller is moved into contact with the vertical guide rail or the horizontal guide rail.

13. The automated warehouse system as set forth in claim 10 , further comprising:
a locking device configured to lock the horizontal guide rail and the movable platform together when transferring the loads into or transferring the loads out of the movable platform.

14. The automated warehouse system as set forth in claim 10 , wherein:
the frame body of the movable platform corresponds to a plurality of adjoining storage areas.

15. An automated warehouse system that stores loads in a plurality of storage areas formed from a plurality of support pillars that extend in the vertical direction and a plurality of beams that extend in the horizontal direction, that transfers the loads to the plurality of storage areas, and that transfers the loads from the plurality of storage areas, the system comprising:
a vertical guide rail that is disposed on a support pillar of the plurality of support pillars;
a horizontal guide rail that is disposed on a beam of the plurality of beams; and
a movable platform havin
