Abstract
A roller conveyor is assembled of several identical modules disposed end to end to define an elongated path for discrete commodities. Each module has a set of parallel idler rollers, an endless flexible belt with an upper reach in contact with the undersides of the rollers of the respective set, an electric motor which drives the belt, and a carrier and pad assembly which biases the upper reach of the belt against the adjacent rollers. The motors can be individually started and arrested in response to signals from photoelectronic detectors which are located above the downstream ends of successive modules and monitor the degree of occupancy of the respective modules.
