ABSTRACT:
A supply unit including a funnel-shaped container for receiving a quantity of unsorted, or randomly oriented, nuts and bolts, a conveyor that is driven, in a reciprocating manner, along an inwardly tapering interior wall of the container. The upper carrying surface of the conveyor dips into the unsorted nuts and bolts on its downward stroke and picks up some of the nuts and bolts. On its upward stroke, or travel, the conveyor cooperates with the adjacent wall to properly orient the majority of the nuts and bolts. Some of the improperly oriented nuts and bolts may fall off the conveyor during its upward travel. Blasts of air, or mechanical deflectors, cause other improperly oriented nuts and bolts to fall back into the container. A step is formed near the top of the container, and the upward travel of the conveyor term mates above the step. The properly oriented nuts and bolts are transferred away from the container by a transport assembly located in proximity to the step. The transport assembly includes an endless belt, and a guide for maintaining the sorted nuts and bolts in proper orientation.
