Abstract
It is known to utilize magnets to assist in separating individual blanks from a stack of blanks. The invention utilizes a pressurized fluid, for example pressurized air, to separate one blank from another. The pressurized air system is utilized in a combination with a pick up device which can pick up individual blanks which are separated from a stack with the assistance of the pressurized air system. Suction cup assemblies located, and providing lift, at the edges or corners of the blank can operate to assist in peeling upwards the edges or corners of the top blank on the stack. These edge or corner mounted suction cup assemblies may be actuated by reciprocadg air cylinders, and may work in conjunction with the pressurized air system.
