Abstract
An apparatus for de-stacking sheet metal blanks uses electro-magnetic pulses to separate sheet metal blanks from a stack of blanks. A fixture supports an electromagnetic attraction device that includes one or more multi-turn electrical coils and one or more insulated metal screens. The coil is electrically connected to a bank of capacitors. The metal screen is disposed in an electrical insulation material and is retained by the fixture between the coil and the top blank of the stack of blanks. Suction cups perform the primary lifting function and are connected to a vacuum source. The suction cups may be supported by the same fixture or another associated fixture that cooperates with the coil and insulated screen.
