Patent ID: 8253064

Claim:
A laser blanking device for cutting rapidly fed coil stock material, the device comprising: a support frame extending from a first end to a second end along a first longitudinal axis; a conveyor supported by the support frame moving in a forward direction from the first end to the second end, the conveyor supporting a strip of coil stock material; a first pinch roll assembly located adjacent to the first end, the first pinch roll assembly feeding a strip of coil stock material in the forward direction from an associated coil onto the conveyor; at least two gantries supported above the conveyor, each gantry having a second longitudinal axis that is generally transverse to the first longitudinal axis; at least one laser head suspended from each gantry, each laser head moveable along the second longitudinal axis; a second pinch roll assembly located adjacent to the second end, the second pinch roll assembly assisting the movement of the strip of coil stock material in the forward direction; wherein the device performs multiple laser cutting operations simultaneously on the strip of coil stock material as the strip of coil stock material moves along the longitudinal axis of the device; and wherein a first gantry of the at least two gantries is located between the first pinch roll assembly and the second pinch roll assembly, and a second gantry of the at least two gantries is located between the second pinch roll assembly and the second end, the laser head suspended from the second gantry completing a cut through the strip of coil stock material that separates a portion of the strip of coil stock material from the remainder of the strip of coil stock material.
