After the selected plurality of traveling loaders 61 are positioned above the tables 13 and 15, a large number of the selected permanent electromagnetic magnets 119 are lowered to remove a part of the selected large number of the permanent electromagnetic magnets 119. The permanent magnet 119 attracts and holds the upper surface of the residual material WB. Then, a large number of the selected permanent magnets 119 are lifted to raise the remaining material WB, and the selected traveling loaders 61 are moved to the right to be positioned above the slat conveyor 41.

After the residual material WB is positioned above the slat conveyor 41, a number of selected permanent electromagnetic magnets 119 are lowered to support the residual material WB on a large number of support rollers 45 in the slat conveyor 41. . Then, the endless chain 43 is run counterclockwise in FIG. 6 to switch from the state in which the upper portion of the residual material lifter table 39 is blocked by the plurality of support rollers 45 to the state in which the upper portion of the residual material lifter table 39 is opened. .

Then, the adsorption holding state of the permanent electromagnetic magnet 119 and the residual material WB is released. As a result, the residual material WB can be completely carried out to the residual material lifter table 39.

According to this embodiment, even if the shape and size of the plate material (the product WA, the remaining material WB) are changed to be carried out during the punching processing or the laser processing of a large number of times, a sufficient number of permanent materials are obtained. With the electromagnetic magnet 119, the product WA and the residual material WB can be moved up and down or transferred in the carrying direction while the upper surfaces of the product WA and the residual material WB are attracted and held. Therefore, the product WA or the residual material WB does not come off from the permanent electromagnetic magnet 119 during the lifting and the transportation, and the product WA or the residual material WB is accurately and appropriately carried out to the product support device 31 or the residual material support device 37.
