LAMINATED WORK PRODUCTION APPARATUS AND PRODUCTION METHOD

A laminated work production apparatus for producing a laminated work hy punching a plate-like metal material (WI) into a plate-like work (W) of a predetermined shape and stacking a plurality of the plate-like works includes a mold (1) for punching the metal material, a stacking jig moving mechanism (2) for moving a stacking jig to a stacking position (A) where the plate-like works (W) are stacked, a retention mechanism (20) for retaining the punched plate-like works (W) at a retaining position different from the stacking position (A) until a preset number is reached, and a knockout mechanism (25) for knocking out a plurality of plate-like works (W) in a punching direction and stacking the plate-like works on the stacking jig arranged at the stacking position (A) when the preset number or plate-like works (W) are retained in the retention mechanism.
