ABSTRACT:
An apparatus is provided for indexing and lifting items from a first conveyer in a first plane and transferring such items to a second conveyor in a second plane it a different level than the first plane. The apparatus includes a transfer assembly for moving the items longitudinally from the first conveyer to the second conveyer. The apparatus also includes at least two longitudinally spaced-apart posts, each post having a top surface. The top surfaces of the posts cooperate to support an item. Connectors connect the posts to the transfer assembly and frame members mount the transfer assembly between the first and second conveyers at an angle relative to at least one of the first and second planes. The posts are configured so that when the transfer assembly is mounted at the angle, the top surfaces are in a single plane which is parallel to at least one of the first and second planes of the first and second conveyors. A drive mechanism is provided for driving the transfer assembly to move the items from the first conveyor to the second conveyor while maintaining the items parallel to one of the first and second planes.
