Abstract
Official abstract text for this publication.
A storage system includes an overhead stocker having a first overhead track, a rack including a plurality of storages arranged vertically, and a crane that travels along the first overhead track and delivers and receives an article to and from the storages; and an overhead transport vehicle system having a second overhead track provided below a lower end of the overhead stocker, and an overhead transport vehicle that travels along the second overhead track and delivers and receives an article to and from a predetermined transfer destination, wherein the first overhead track has an elevating track capable of supporting and lowering the crane that is stopped traveling at a portion deviated from the second overhead track in planar view.
First claim
Opening claim text (preview).
The invention claimed is: 1. A storage system comprising: an overhead stocker having a first overhead track, a rack including a plurality of storages arranged vertically, and a crane that travels along the first overhead track and delivers and receives an article to and from the storages; and an overhead transport vehicle system having a second overhead track provided below a lower end of the overhead stocker, and an overhead transport vehicle that travels along the second overhead track and delivers and receives an article to and from a predetermined transfer destination, wherein the first overhead track has an elevating track capable of supporting and lowering the crane that is stopped traveling at a portion deviated from the second overhead track in planar view. 2. The storage system according to claim 1 , wherein the elevating track is provided directly above a worker passage. 3. The storage system according to claim 1 , further comprising: a suspending member that suspends and holds the elevating track, and an elevating track driver that raises and lowers the elevating track by winding or feeding out the suspending member. 4. The storage system according to claim 1 , further comprising: a transport device that transports an article vertically between the overhead stocker and the overhead transport vehicle system, and a placement portion provided directly below the elevating track that allows both the overhead transport vehicle and the transport device to deliver and receive an article, wherein the placement portion is retractable from directly below the elevating track. 5. The storage system according to claim 4 , wherein the placement portion is bridged between a pair of other placement portions, and the overhead transport vehicle delivers and receives an article to and from the other placement portions.
