Abstract
A conveyor controlling device which can reduce production costs and can be easily attached. The presence or absence of a load in the conveyor portion in the local zone and a plurality of selected downstream zones is detected. The controlling device stops the drive of the local corresponding zone when a signal indicates the presence of loads in the local zone and in all of the downstream zones. The conveyor controlling device drives the local corresponding zone when the downstream presence signal indicates that at least one downstream zone is vacant. This controlling device provides a simple method for controlling an accumulating conveyor.
