  • Publication number: 20120275886
    Abstract: A transport system includes a first track that passes above loading ports of the processing devices, and an overhead travelling vehicle that travels along the first track and includes a hoist. A second track is below the first track, passes above the loading ports, and is disposed in parallel or substantially in parallel with the first track. A buffer is provided below the second track at a position higher than the loading ports, and is arranged such that the articles can pass in a vertical direction over the loading ports. The buffer is disposed such that the articles can pass through the height position of the buffer in a vertical direction over the loading ports. A local vehicle travels along the second track and includes a hoist to perform delivery and receipt of the articles between the buffer and the loading ports.

  • Publication number: 20120128455
    Abstract: In a transport system, two drop prevention barriers and a drop prevention mechanism are provided along a periphery of a load port where a transported article has been placed. The drop prevention barriers and the drop prevention mechanism are arranged on three sides around the periphery of the load port and a remaining side is open along a first direction. The drop preventing mechanism includes a retaining member rotatably supported on a bracket. When a transported article moves along the first direction, the retaining member is pushed by a transport device such that it rotates from an initial position and retracts in an opposite direction from where a path is located. When the transported article has been loaded onto the load port, the retaining member returns to the initial position such that it is arranged slightly above the transported article.
