Vibratory belt separator for blow-molded parts

摘要

A separator for blow-molded parts, which separator includes a plurality of endless belts movably supported between a pair of horizontally spaced pulleys, one of which is a drive pulley. The belts, preferably of circular cross section, have upper reaches extending in approximately parallel but sidewardly spaced relationship to define small gaps therebetween through which scrap parts can pass. The other parts remain on the belt and are transported to a discharge location. The adjacent belts are preferably driven at slightly different speeds to facilitate agitation and dislodgement of scrap parts so that they can move into and through the gaps. The ends of the belts are supported by rotatable end idler pulleys, alternate ones of which preferably have exterior belt-engaging profiles which are noncircular relative to the rotational axis to effect cyclic vertical displacement of the upper reaches of alternate belts.
