<p>Apparatus for arranging and stacking articles including an infeed conveyor in which a rotator is mounted, operable to physically lift an article from the conveyor and rotate it to a desired orientation. Downstream from the rotator is a layer arranging table including elongate rollers powered for rotation in the same direction as the infeed conveyor to carry articles onto the arranging table. A plurality of endless conveyor chains are interposed between the rollers with their upper reaches driven in a direction transversely of the direction of movement of an article on the infeed conveyor. The rollers and chains are shiftable vertically relative to each other so that an article is supported on its underside and positively carried either in the direction of the infeed conveyor or transversely thereof. An elongate carriage is mounted for vertical shifting relative to the arranging table at the downstream end thereof. A powered roller bed is mounted on the carriage for movement longitudinally thereof between a position adjacent the arranging table and a position spaced downstream therefrom over an article receiving area. A fence is shiftable into a position behind articles on the roller bed whereby on return shifting of the roller bed articles are stripped therefrom onto the article receiving area. Powered means for shifting the carriage vertically is operable to press the roller bed down stop previously deposited layers to flatten the tops thereof to receive the next layer.</p> |
