ABSTRACT:
A roller conveyor bed is formed by a plurality of driven conveyor spools or rollers rotating in the same direction for conveying and sorting objects. The conveyor rollers define a substantially common conveyor plane along the upper surfaces of the conveyor rollers and are selectively spaced apart for selectively passing objects through the selective spaces between conveyor rollers thereby sorting the objects by a size dimension. An anti-pinch surface is positioned adjacent to each of the conveyor rollers on the downstream side of the conveyor roller with reference to the conveying direction. Each surface is positioned below the conveyor plane and provides an anti-pinch surface which substantially shields the downstream side of the adjacent conveyor roller where the roller surface is turning in a downward direction. The conveyor rollers are spaced apart so that the anti-pinch surface shielding the downstream side of one conveyor roller and the upwardly turning surface of the next spaced apart roller define the selective space for passing and sorting objects. The anti-pinch surface is an elongate stationary curved surface facing convex side upward or a second roller of substantially smaller diameter abutting the downstream side of the conveyor roller. A proportional spacing mechanism is coupled to the spools or rollers for variable spacing of the rollers while maintaining equal spacing or proportional spacing between the rollers.
