Then, only the remaining material Z is held by the 3-jaw chuck 401, and the product S is placed on the placement bar 115 of the placement unit 112. After the lifting platform 55 stops, the support roller 654 descends to a fixed position. In this way, the plate material W is sorted into the remaining material Z and the product S.

  When sorting, the elevating platform 55 and the support roller 654 may be synchronously operated and lowered at the same speed while the mounting portion 112 is reciprocated in the front-rear direction or the substantially horizontal direction with a small width. In addition, after the lifting platform 55 and the support roller 654 are slightly lowered, the placement unit 112 may be reciprocated in the front-rear direction or the substantially horizontal direction to perform sorting. Further, instead of reciprocating the mounting portion 112, it may be sorted by vibrating.

  Next, the mounting portion 112 is moved backward by the forward / backward moving portion 111. The lifting platform 55 rises to a position where the product S is placed on the plate material pallet 13. After the placing part 112 is moved forward by the back-and-forth moving part 111, the lifting / lowering base 55 moves down slightly and places the product S on the plate material pallet 13. Then, the placing part 112 is moved backward to the lifting platform 55 side by the longitudinal movement part 111.

  Sprockets 725 are rotatably fixed to the left and right beam members provided on the front column 2 and the rear column 2 of the shelf frame 1 by brackets (not shown), respectively.

  One end of the chain 726 is connected to the upper part of the lifting frame 721, spans the sprocket 725, the sprocket 724, and the sprocket 723, and the other end of the chain 726 is connected to the lower part of the lifting frame 721. The lifting frame 721 is connected by two chains 726 on the left and right.

  When the motor 729 is driven to rotate in the forward and reverse directions, the drive shaft 728 rotates, and an elevating frame 721 suspended by a chain 726 spanned between the sprocket 725 and the upper sprocket 724 provided on the drive shaft 728 and the lower sprocket 723. Is guided by a guide 722 and moves up and down in a substantially vertical direction.

  A three-claw chuck 401 is attached to the lifting frame 721 so that the claw of the three-claw chuck 401 faces downward. The inner nail 402 is attached to the nail. The inner claw 402 is smaller than the hole diameter of the hole H processed into the remaining material Z when the inner claw 402 is closed, and is tapered so that the tip can be easily inserted into the hole H.

  When the product S is processed by the plate material processing machine 250, a plurality of holes H are processed at appropriate intervals in the peripheral portion of the plate material P, that is, in the portion that becomes the remaining material Z. The hole H is machined to a position where it does not interfere with the forward / backward moving portion 111 when the 3-jaw chuck 401 holds the remaining material Z. Further, the hole H is machined to a position where it does not interfere with the mounting rod 115 when the inner claw 402 of the 3-jaw chuck 401 holds the remaining material Z. The 3-jaw chuck 401 inserts the inner claw 402 into the hole H, opens the inner claw 402 and holds the remaining material Z. Therefore, when the processed plate material W is placed on the mounting rod 115 and sorted, the center of the hole H processed in the peripheral portion of the plate material P and the three-claw chuck 401 attached to the lifting frame 721 are arranged. The 3-jaw chuck 401 is disposed so that the axis coincides vertically.

After holding the remaining material Z of the processed plate material W by the three-jaw chuck 401, the elevating frame 721 is slightly raised and stopped. Thereafter, the product S can be sorted by reciprocating the placement part 112 back and forth or in a substantially horizontal direction with a small width while supporting the tip of the placement bar 115 with the support roller 654. At this time, the product S may be sorted by vibrating the mounting portion 112 in the front-rear direction or the substantially horizontal direction.

  Further, after holding the remaining material Z from the processed plate material W by the three-claw chuck 401, the lifting frame 721 is slightly raised, and at the same time, the mounting portion 115 is supported by the support roller 654 while the mounting portion 115 is supported. The products S can also be sorted by reciprocating 112 in the front-rear direction or in the substantially horizontal direction. At this time, the product S may be sorted by vibrating the mounting portion 112 in the front-rear direction or the substantially horizontal direction.

  In this way, the product S that cannot be sorted because the product S is caught by the dross attached to the lower surface of the product S or the remaining material Z when laser cutting is performed by the plate material processing machine 250 (laser processing machine) as in the first embodiment. By reciprocating or vibrating the product S, a load is also applied to the dross attached when the product S on the placement unit 112 hits the remaining material Z held by the holding unit 400, and the attached dross is removed. It becomes possible to sort.

Further, instead of reciprocating the mounting portion 112, it may be sorted by vibrating.

  Next, after the lift 55 is slightly raised, the placing part 112 is moved backward by the forward / backward moving part 111, and the lift 55 is raised to a position where the product S is placed on the plate material pallet 13. After the placing part 112 is moved forward by the back-and-forth moving part 111, the lifting platform 55 is lowered and the product S is placed on the plate material pallet 13. Then, the placing part 112 is moved backward to the lifting platform 55 side by the longitudinal movement part 111.

  Next, the lifting / lowering base 55 moves to a position where the rest material Z held by the 3-jaw chuck 401 is received by the placement unit 112, and the remaining material Z held by the 3-jaw chuck 401 by the back-and-forth movement unit 111.
