Abstract

PURPOSE:To shorten a span of delivery access time by judging the extent of possibility in the delivery of a distant rack from an outlet and an empty rack proximate to the outlet, and making such a car as high in delivery possibility so as to be relocated. CONSTITUTION:A rack control part 15 receives a command of a relocation control part 14, and it finds a relocation judging index alphai to the whole rack from an equation alphai=(ti-Tp) di (hereat, i shows a rack number, t1 is car incoming time of a rack No. i, tp is the present time, di is a distance from an outlet of a car of the rack No. i to a rack of the rack N. i, respectively), thereby finding the maximum rack number of the judging index alphai. Next, it retrieves an empty rack which comes to minimum in a distance from the outlet. And, a distance dj from the outlet of a judging index maximum rack is compared with a distance dk from the outlet of the empty rack, and when dk>dk is the case, the empty rack is set down to the relocating destination, parking ID is written in space ID, and this parking ID is rewritten to empty and car incoming time to zero, respectively. And, both rack numbers are fed to the relocation control part 14. With this operation, a stacker crane control part 16 moves a car on the relocation subject rack to the relocating destination empty rack. With this constitution, delivery access time can be shortened.
