ABSTRACT:
A conveyor includes a frame and a series of closely spaced rollers. Each roller has an outer circumferential surface, a first end portion journalled on an axle supported by the frame on one side of the conveyor and a second end portion journalled on an axle supported by the frame on the other side of the conveyor. The rollers include master rollers and slave rollers interpersed between the master rollers. A drive train is provided for driving every roller in the series of closely spaced rollers. The drive train includes a primary drive train for driving the master rollers and secondary drive trains for driving the slave rollers from respective master rollers. The primary drive train includes relatively large diameter high torque primary sprockets mounted on the outer circumferential surfaces of the first end portion of the master rollers and chains connecting and driving the primary sprockets. The secondary drive train includes relatively small diameter low torque secondary sprockets mounted on the axial ends of the second end portion of the rollers and chains connecting and driving the secondary sprockets. The relatively large diameter primary sprockets form a high profile on one side of the conveyor. The relatively small diameter secondary sprockets form a low profile on the other side of the conveyor.
