Abstract

PURPOSE:To promote the internal smoothness of service by judging whether an amount of stock indicating information exceeds the number of conveyor tracks, distributing it into an indicable portion and an indication wait portion according to this judgment. And when an acceptable on a conveyor becomes nothing, making it so as to output indications set to indication waiting, in an above-captioned controller for the conveyor or the like. CONSTITUTION:When each stock indication is inputted from input units 1, 2, an input indication judging means 3 judges whether this stock indication exceeds the track number of a stock conveyor or not. When exceeding it, the track number is stored in a stock waiting indication table file 5 and when unexceeded, it is stored in a stock indication table file 4, respectively. Then, the indication of the stock indication table file 4 is outputted to an operation indicating output means 6, and it is conveyed by a physical distribution conveyor 7. When an acceptable space signal input means 8 detects a fact that there is no acceptable space, a wait indicating portion is transferred to the stock indication table file 4 and stocked likewise. With this constitution, it can be smoothly processed.
