ABSTRACT:
An improved conveying apparatus and an electronic control module for conveying systems is disclosed. The conveying apparatus includes two or more belt conveyors operating in tandem and is controlled by separate electrical circuits so that each conveyor in the system operates independently and on automatic demand of a given or preset response. The electrical control for the conveying system includes a timer which is adapted to time each object being conveyed to transverse the length of the conveyor and to stop the conveyor when the object is not present along the length of the belt. The timed circuitry further includes a memory function so that if a conveyor stops for any reason, it will restart and operate for the unexpired segment of the time required to provide a total cycle. This assures that the object being conveyed is never left on a conveyor belt unintentionally and eliminates all unnecessary operation or running of the conveyors.
