Abstract:
1. A laminated work production method for producing a laminated work by punching a plate-like metal material into a plate-like work of a predetermined shape and stacking a plurality of the plate-like works, comprising the steps of: causing the punched plate-like works to be retained; knocking out a plurality of plate-like works in a punching direction and successively stacking the plate-like works on a first stacking jig arranged at a stacking position on an extension of the punching direction of a mold when a preset number of plate-like works are retained; moving the first stacking jig, on which a predetermined number of plate-like works are stacked, to a loading/unloading position distant from the stacking position in the punching direction and moving the stacking jig to a position away from the punching direction; subsequently introducing an empty first stacking jig to the loading/unloading position and moving the empty stacking jig to the stacking position along the punching direction of the plate-like works; and unloading the first stacking jig moved to the position away from the punching direction to the outside of the mold, transferring the plate-like works from the first stacking jig to a second stacking jig outside the mold, and transferring the plate-like work to the second stacking jig while rotationally stacking the plate-like work every time the plate-like work is transferred.
