Further, the front conveyor 5, the rotary table 39, the carry-out conveyor 47
Is operated to carry out the product WA appropriately.

When the residual material W is generated after cutting the predetermined material W, the output device 61 causes the front conveyor 5, the rotary table 39, and the transfer conveyor 2.
By operating 3 appropriately, the residual material W is transferred to the dimension detecting device 49 side and is positioned at an appropriate position close to the dimension detecting device 49 (steps 5 and 6 in FIG. 4). Next, the dimension detecting device 49 detects the dimension of the remaining material W in three directions (step 7 in FIG. 4). Then, the detected size is stored in the storage device 53, the pallet information corresponding to the material information of the remaining material W is searched from the large number of pallet information by the calculation unit 67, and the three directions detected by the information card are detected. Write the dimensions of (step 8 in FIG. 4). After the step 8 is completed, the output device 6
By appropriately operating the transfer conveyor 23, the crane device 33, and the pallet transfer device 27 by means of 1, the residual material W can be transferred from a position close to the dimension detection device 49 to a predetermined divided storage part 17a in the material storage device 13. (Step 9 in FIG. 4). At this time, the information card is also transferred integrally with the remaining material W to a predetermined divided storage portion 17a.

After the step 8 is completed, if the cutting process is performed on the other material W, the process is fed back to the step 1, and if the cutting process is not performed on the other material W, a series of work is performed. End (Step 1 in FIG. 4)
0). If a plurality of product information has already been input, the feedback is given to step 2 instead of step 1.

According to the present embodiment as described above, after cutting the predetermined material W, the three dimensions of the residual material W are detected, and the dimensions detected by the storage device 53 are set to the predetermined material. Since the information is stored as the material information of W, it is possible to quickly deal with the case where the residual material W is cut and processed, and the work efficiency is improved.

The present invention is not limited to the above description of the embodiments, but can be implemented in various modes by making other appropriate changes.
