Abstract
A conveyor with a straight pathway has laterally spaced side walls with opposing banks of driven roller assemblies mounted thereon. Each roller assembly has a shaft, a roller, and a driven pulley. The pulleys of assemblies on a side wall are driven by an endless positive drive belt that has teeth for meshing with the grooves on a driven pulley. The belt is maintained in its meshed relationship with the driven pulleys by an anti-camming surface that obstructs the belt from being cammed out of its meshed relationship. The belt is laterally guided by an annular ridge on the pulleys and the outside surface of the side wall. A docking station for product carriers is also described. A transitional conveyor embodiment with a curved pathway has spaced curved alignments of bearing mounts for mounting roller assemblies thereon. The roller assemblies have dual pulleys which are each paired with the dual pulley of an adjacent assembly by an endless belt, such as an O-ring. The rotation of a primary driver pulley is thus passed from pulley to pulley along an alignment.
