ABSTRACT:
A roller conveyor assembly is adapted to prevent backed up pressure on a conveyor line when a load container is compelled to stop. The roller conveyor assembly comprises a plurality of conveyor rollers (2) mounted in a frame (1) so as to form a travelling surface. The travelling surface is divided into a plurality of successive zones each containing a load sensing means (9), a group of conveyor rollers (2a), and a control means. When a stalled container (N-1) is sensed in a reference zone, the control means is operative to disengage the transmission of power to a preceding, adjacent, upstream zone upon the detection of a load container (N-2) in the upstream zone. In this manner, a collision between load containers is prevented.
