Abstract

A lift table is movably mounted on a frame adjacent to one end of a conveyor belt which deposits sheets of corrugated board or the like on the lift table. As the sheets pile up on the lift table, the table is automatically lowered so that the top of the stack remains below the level of the conveyor belt. When the stack reaches a predetermined height, the conveyor belt is blocked to interrupt the delivery of sheets, and the stack is moved off the lift table by live rollers thereon. The lift table is then raised at a relatively high speed to the level of the conveyor belt, which is subsequently unblocked to start a new stack. The lift table has a pair of torsion bars journalled to opposite sides of the lift table parallel to the table top. Four pairs of sprockets are rigidly attached to the corresponding ends of the torsion bars. Two pairs of leveling chains are attached at both ends to the frame and operatively engage corresponding sprockets to rotate the torsion bars and maintain the lift table level as it is raised and lowered. The lift table is raised and lowered by hydraulic cylinders which are linked to the lift table by chains. The hydraulic cylinders are mounted within the upper frame members to conserve space.
