Manufacturing apparatus for heat dissipation fins

A manufacturing apparatus for heat dissipation fins comprising:

• a press apparatus provided with a mold apparatus that forms cutout portions in an unmachined metal thin plate, the unmachined metal thin plate having been supplied from a material supplying unit, to form a heat dissipation fin molding;
• a conveying apparatus that supplies the thin plate to the press apparatus and conveys the heat dissipation fin molding from the press apparatus;
• a cut-off apparatus that cuts the heat dissipation fin molding into a predetermined length to form a heat dissipation fin;
• a holder apparatus including:
• a pair of holders that hold the heat dissipation fin molding and the heat dissipation fin and are capable of moving together and apart between positions to a side of the heat dissipation fin molding, the heat dissipation fin molding having passed through the cutoff apparatus and protruding in a conveying direction from the cutoff apparatus, and holding positions for holding the heat dissipation fin molding;
• and a holder opening/closing mechanism that moves the pair of holders together and apart;
• a stacker apparatus that is disposed below the holder apparatus to stack heat dissipation fins that have been cut into a predetermined length by the cutoff apparatus and includes:
• a stacker guide holder unit on which a stacker guide, the stacker guide having been inserted through the heat dissipation fin held by the holder apparatus, is erected;
• a fin receiving portion that contacts a lower surface of a lowest heat dissipation fin out of the heat dissipation fins through which the stacker guide passes through;
• and a moving mechanism that moves the fin receiving portion along the stacker guide;
• a drop guide apparatus including:
• a drop guide disposed above the pair of holders at a position on a plane that enables the drop guide to be inserted into one of the cutout portions;
• and
• a drop guide moving unit that moves the drop guide toward and away from the stacker apparatus;
• and
• an operation control unit that controls respective operations of at least the cutoff apparatus, the holder apparatus, the stacker apparatus, and the drop guide apparatus.
