<p>PURPOSE:To enable correction and addition of a stop position to a three-dimensional warehouse by fixing a signal generator to a transfer loader such as a stacker crane or the like and storing rack position information to control the transfer loader through a control unit. CONSTITUTION:A stacker crane 13 is provided with a frame 14 running along a rack row 12 and with a cage 15 mounted on the frame 14 in such a manner as to elevate so as to move horizontally and vertically. The crane 13 is also provided with pulse generators 16 and 17 to generate pulses at every fixed distance in case of running or elevating. The number of pulses is counted by a counter connected to a control unit 18 mounted on the cage 15. In this arrangement, according to a loading the unloading command, the position information is taken out to control a transfer loader through a control unit, whereby even if a rack position goes wrong such as inclination, the rack position information can be simply corrected to eliminate an obstacle to automatic operation.</p> |
