Abstract
A machine for orienting and stacking receptacles, such as cups having a base end and a mouth end, which machine includes a receiving area wherein the cups are initially received and are then fed to an upright, angularly disposed conveyor, the cups being received between bars presented by the conveyor. As the cups are moved upwardly by the conveyor, they come into engagement with an angularly disposed orienting roller which spans the width of the conveyor and contacts the cups to shift them into a common, oriented relationship with the mouths all facing in one direction and the bases in another. After orientation, the cups pass over the top of the conveyor and are removed therefrom and carried to a delivery location. The removal of the cups from the conveyor is accomplished by a vacuum which is drawn adjacent the top end of the conveyor. At the delivery location there is provided a pair of spinning rolls which rotate in the same direction at different speeds and which serve to draw the cups, in their aligned, oriented relationship, therealong and into a final, stacked relationship whereby they may be removed from the machine for subsequent handling or packaging.
