ABSTRACT:
An apparatus is provided for automatically denesting an article from a stack of nested articles. The apparatus includes a frame supporting the stack of articles in an elevated downwardly inclined position relative to a conveyor unit defining a substantially horizontal plane. Adjustably mounted on the frame for controlled movement along a path inclined upwardly towards the lower end article of the supported stack is a carrier unit. Carried on the carrier unit are elements adjustable independently of the unit between operative and inoperative modes. When the carrier unit approaches the upper limit of its upward movement along the path, the elements carried thereby are adjusted to an operative mode and frictionally engage the lowermost article of the stack and cause the latter to be denested from the stack as the carrier unit commences its downward movement along the path. The elements are adjusted to an inoperative mode when the carrier unit has moved downwardly a predetermined distance along the path thereby releasing the denested article onto the conveyor unit. When the carrier unit assumes a normal rest position, it is disposed beneath the horizontal plane.
