The plurality of product plate materials W2a, W2b,... Are collectively conveyed to the product plate material carry-out area B. In the product plate material carry-out area B, the pad support frame 20 is lowered to release the adsorption of the holding means 4, and a plurality of product plate materials W2a, W2b,. When the individual placement positions are determined for each product plate material W2a, W2b, the traveling body 5 is placed so that the product plate materials W2a, W2b,. The product plate materials W2a, W2b,... Are sequentially released by the holding means 4 and released.
[0019]
In this way, in this plate material conveying apparatus, a plurality of product plate materials W2a, W2b,... Are conveyed from the plate material processing machine 3 to the carry-out area B while being held by the holding means 4, so that the plate material conveying efficiency is improved. Thereby, the waiting time of the plate material processing machine 3 is shortened, and the operating rate of the plate material processing machine 3 is also improved.
In this case, after adsorbing one product plate material W2a by the holding means 4, the traveling body 5 is moved backward with respect to the plate material processing machine 3 to a position where the plate material processing machine 3 can cut out the next product plate material W2b. After the holding means 4 adsorbs one product plate material W2a, the moving amount of the traveling body 5 is reduced until the next product plate material W2b is adsorbed, and the conveyance time can be shortened.
Further, the transport control means 2 controls the holding means 4 different from the holding means 4 that already holds the product plate material W2a to move to a position where the next cut product plate material W2b is held. Therefore, it is possible to hold a plurality of product plate materials W2a, W2b,... Without causing problems such as mutual interference of the product plate materials W2a, W2b,.
