<p>PURPOSE:To enable highly efficient operation of a crane by adding a warehousing sensor on a carry-in conveyer and a function for abandonedly moving the crane by the warehousing sensor into a crane schedule. CONSTITUTION:When a warehousing sensor 6 provided in the midway of a carry-in conveyer 6 on the upstream side from a warehousing station 3 detects a work 4, the sensor instructs preparation for warehousing to a stacker crane 1. That is, if the crane 1 is waiting for warehousing or shipment, the crane 1 starts to move toward the station 3. When the sensor 6 detects the work 4, the crane immediately starts to move to the warehousing station, and the crane arrives at the warehousing station at the same time when the work is ready for being loaded on the warehousing station. Therefore with such timing that the crane starts to move to the warehousing station as the station is ready for loading, permitting warehousing to be done in a shorter time than conventional methods.</p> |
