<p>PURPOSE:To efficiently control the motion of a stacker crane and thereby aim at an efficient take-in take-out of designated members by keeping one or more empty shelves without fail on a priority processing dedicated shelf selected in order of short drawing device transfer time. CONSTITUTION:Of all shelves in a high-rise storing shelves 1, a few shelves Hf are selected in order of short transfer time from a home position P of a stacker crane 2 and made priority processing dedicated shelves 6 while other shelves H1 to H6 are made regular processing shelves 7. If a take-out objective member is stored inside the priority processing dedicated shelf 6 when the member is to be taken out from the high-rise storage shelf 1, the take-out objective member is caused to be taken out from the priority processing dedicated shelf 6 and if the take-out objective member is not stored inside the shelf 6, 8 member having the lowest probability of being taken out next, among the stored members inside the priority processing dedicated shelf 6, is taken out and stored inside a shelf allotted on the basis of one to one against this member inside the regular processing shelf 7. Thereafter, this member is taken out from the inside of the shelf where the take-out designated member inside the regular processing shelf 7 is stored and issued.</p> |
