ABSTRACT:
A suction wheel is mounted laterally adjacent a horizontal conveyor and at an elevation slightly thereabove. The suction wheel is movable laterally between that position and an inward position partially overlapping the conveyor. A plurality of peripheral ports are provided in the suction wheel which is mounted for rotation about a vertical axis at a peripheral speed correspond to the speed of the conveyor. A manifold rests upon the suction wheel, but is held stationary against rotation. The manifold has at least three ports disposed in the path of movement of the suction wheel ports. A vacuum source is operatively coupled to at least two ports in the manifold, and a pressurized fluid source is operatively coupled to at least one of the ports in the manifold. The suction wheel operates intermittently. Only when an article is to be removed from the conveyor, does the suction wheel move inwardly to remove the reject articles.
