Variable load asynchronous driving for a conveyor

摘要

The load dependent asynchronous drive for a multiple belt conveyor feed (12,24) with a preset feed speed has individual motors (M) for each belt. The individual conveyors have sensors (LS) for feed speed and a regulator corrects the conveyors. The sensors each determine a time gap to the directly adjacent conveyed goods (i plus 1,2) during the movement past the sensor. The time gaps can be used to control the asynchronous motors.
