The length of the sheet 18 is from the second path D2; e) the size of the cut sheet: as shown in the fifteenth to sixteenth figures, the input one needs 201242735 to obtain the value N to the input area 162, the sawing machine 144 moves along the third path d3 toward the sheet 18; then, the feeding device 12' drives the sheet 18 to move 'until the third side 186 of the sheet 18 and the saw blade 146 of the saw 144 are The relative distance on the first path D1 is equal to the demand value N, the sawing machine 144 is activated to rotate the saw blade 146 and the moving device 14 traverses the sheet 18 to allow the saw blade to cut the sheet 18. Therefore, the sheet size processing method provided by the present invention only needs a single sensor 142 and reciprocates once with the feeding device 12 and the mobile device 14 moves once in one direction when measuring the size of the sheet 18 . This will save time in measuring the work and save time in sheet metal processing. It should be noted that, in the foregoing step e), the action of inputting the demand value to the input area may also be completed in one of step a), step b), step c) and step d). It is worth mentioning that, after the sheet 18 is subjected to cutting, if its size on the first path is still greater than the required value N, the cutting can be directly performed again. Therefore, it can also be in step e). After the saw blade 146 cuts the plate 18, if the third side of the plate 18 and the saw blade 146 of the sawing machine 144 are greater than the required value N on the first path D1, the feeding device 12 will drive the The sheet 18 is moved until the third side 186 of the sheet 18 and the saw blade 146 are at a relative distance N on the first path D1 equal to the demand value N, allowing the saw blade 146 to cut the sheet 18. However, if the case where the demand value N is not input is considered, the controller 16 further has a size database D (not shown) which stores a plurality of preset values P (not shown). In step e), if the demand value N is not input, the controller 16 automatically searches for the preset value P ' suitable for the sheet 18 from the preset values p. The sawing machine 144 follows the The third path D3 moves toward the sheet 18 in the vicinity of 201242735; then, the feeding device 丨2 drives the sheet 18 to move 'until the third side 186 of the sheet 18 and the saw blade 146 of the saw 144 are in the first path. The relative distance on D1 is equal to the predetermined value p, and the sawing machine 144 is activated to rotate the saw blade 146 and the moving device 14 traverses the sheet 18 to allow the saw blade 146 to cut the sheet 18. In addition, please refer to FIG. 17 for a third preferred embodiment of the present invention, which is substantially the same as the second preferred embodiment, except that it is considered that the edge of the sheet material 18 may be generated after being impacted by an external force. The edge is deformed, or the moisture is infiltrated into the edge of the sheet to cause expansion. If the sheet 18 is directly cut, the edge deformation or expansion will continue to be retained. In the above case, in the step e), the feeding device 12 drives the plate 18 to move, and the third side 186 of the plate 18 and the ore piece 146 of the miner 144 are first in the first path. The relative distance on the control D1 is equal to a de-edge value c. After the slab 146 cuts the sheet 18, the sheet 18 is driven by the feeding device 12 until the second side 186 and the 5 hai mining cutter 144 The relative distance of the sheet 146 on the first path D1 is equal to the demand value N, and the saw blade 46 is then cut to the sheet 18. By the setting of the de-edge value C described above, the portion of the sheet 18 which is likely to be deformed or expanded can be removed, ensuring that the edge of the subsequently cut sheet is intact. Referring to Figures 18 through 19, a fourth preferred embodiment of the present invention will be described. The difference between the preferred embodiment and the second preferred embodiment is that, in step e), the demand value N has a first value because the size of the general plate material is completed after cutting the adjacent sides. > and a second value N2, the feeding device 12 drives the sheet 18 to move until the third side 186 of the sheet and the saw blade 146 of the sawing machine 144 have a relative distance on the first path D1 equal to the first value N1. The sawing machine 144 moves along the third path D3 toward the 201242735 direction of the sheet, activates the sawing machine 144 to rotate the saw blade ι46 and the moving device 14 traverses the sheet 18, 'let the piece 146 cutting the sheet 18; then rotating the sheet 18 to place the second side 184 into the feeding device 12, and being driven by the feeding device 12 until the fourth side 188 of the sheet 18 and the cutting piece of the sawing machine 144 146, on the first path D1, the relative distance is equal to the second value N2, the miner 144 is activated to rotate the saw blade 146 and the moving device 14 traverses the sheet 18, allowing the saw blade 146 to cut the sheet. The cutting work is completed by cutting the third side 186 and the fourth side 188 of the sheet as described above. With the sheet size measurement processing method provided by the present invention, the following effects can be obtained: 1. Using a single sensor and planning a simple measurement path, the measurement operation time and cost can be saved. Second, the use of time-saving measurement methods, and the processing of the sheet size after the completion of the measurement operation, it can reduce the processing costs.
