Abstract
A workpiece accumulator system for a stamping machine includes linear actuators, nesting blocks, exit rails, and a first controller. The nesting blocks are disposed on moveable members of the linear actuators and arranged to vertically stack workpieces being fabricated by the stamping machine. The first controller communicates with a second controller that controls the stamping machine. The first controller controls the linear positions of the linear actuators to retract the nesting blocks from an initial position to accommodate placement of the one of the plurality of workpieces in a stack on the nesting blocks. The linear actuators are controlled to retract the nesting blocks to fully retracted positions to place the plurality of workpieces in the stack onto the exit rails when a quantity of the plurality of workpieces in the stack is equal to a desired quantity.
