PURPOSE:To improve the operating ratio of a crane by designating a housing position according to data on out-frequency during a fixed period, and changing the housing position depending upon the frequency in automatic storehouse with a crane. CONSTITUTION:A main control portion 1 is adapted to display an out-command on a display portion 11, and read out an address. Simultaneously, +1 is counted on an out-frequency counter 9. In response to this operation, a crane 7 carries housed materials to an out station, and an operator picks up the material, the remaining materials being housed again by the crane 7. At this time, out-frequency data during a fixed period are sent to a housing address designating portion 10 by a housing address setting button 12a, and a new housing address is set from an empty housing address area and an individual address to house the material. Thus, the housing position is determined according to the out-frequency so as to improve the crane operating ratio. |
