WIPO Patent Application WO/2013/183384
Kind Code:

Abstract:
When an overhead traveling vehicle (2) and a local platform truck (4) perform transfers to or from a buffer (10, 11), in order to enable the overhead traveling vehicle (2) and local platform truck (4) to perform transfer-time communication according to a procedure during and to reliably avoid interference between the overhead traveling vehicle (2) and the local platform truck (4), a track (8) of the local platform truck is provided directly below a track (6) of the overhead traveling vehicle, and the overhead traveling vehicle (2) and the local platform truck (4) can transfer articles to and from the same transfer destination. the overhead traveling vehicle (2) and the local platform truck (4) are configured so as to perform transfers to or from the transfer destination after exchanging a transfer request signal and a transfer confirmation signal. Exclusive control is performed such that the transfer confirmation signal is sent in response to only one of a transfer request signal for the overhead traveling vehicle (2) and a transfer request signal for the local platform truck (4), and such that a transfer confirmation signal is not sent in response to a transfer request signal for the overhead traveling vehicle (2) for the position where the local platform truck (4) is stopping or the range in which the local platform truck (4) is travelling.
