The above trimming amount is usually about 1 to 1.5 times the plate thickness and is almost constant, but there are many errors in cutting accuracy at the leveler line, etc. For example, if the cutting dimension of the plate is at the limit of the allowable value, the trimming amount may be By doing so, the dimensions of the plate material will fall below the allowable value. Therefore, even if the amount of trimming is constant for each board, when trying to divide a board into n equal parts of a predetermined size, in some cases it may only be possible to divide the board into (n-1) equal parts, and the nth part will be scrapped. Therefore, the dimensions are large, which causes problems such as poor yield.

Next, the description will be made with reference to FIG. 2 and subsequent figures. First, FIG. 2 shows the state in which the plate material W is cut when the above-mentioned trimming is performed without using the method of the present invention. That is, in this case, the length A of the plate material W cut by the leveler line is set so that the trimming amount is d and the length a of the plate material to be divided is n so that n pieces can be obtained, as shown in the figure. It is calculated in advance, but due to variations in the accuracy of the leveler line, the dimension A becomes negative by C.
When A - C occurs, the dimensions of the last n-th plate will be outside the negative tolerance and will be scrapped.

Therefore, in the present invention, cutting is performed in the following manner. In FIG. 1, it is assumed that a plate material W of a certain size is now set in the plate material supply device 1. In this state, the plate material supply device 1 and the cutting machine 7 are operated under NC control, and the plate material W is cut by the feed cutting machine 7 by the plate material supply device 1 by the input cutting dimension. Prior to this, the length of the plate material W is first measured.

For this purpose, the plate material W is gripped by the clamper 3 of the plate material supply device 1, and the origin of the control device is corrected so that the end surface of the plate material W is within the measurement range of the detection device 11. That is, as shown in FIG. 1, one front end of the plate W is placed between the light projecting section 13 and the light receiving section 17. At this time, a part of the plate material W blocks the parallel light beam 15 from the light projecting section 13.

In this way, when the plate material W blocks the parallel light beam 15, a shadow is created on the light receiving section 17, so the value l2 obtained by calculating the size of the shadow and the value l1 (held by the clamp 3) after the origin correction are calculated. The length l 1 +l 2 of the plate W is measured from the distance between the rear end of the plate W and the light receiving section 17.

Further, the allowable error value in the size B of the plate material W required to cut, for example, n plates with dimension b when cut by the cutting machine 7 is input into the control device in advance, and the tolerance value in the detection device 11 Therefore, only when the accuracy error when measuring the length of the plate material W is within the allowable error, a control signal for dividing the plate material W into n equal parts is issued. Thereafter, the plate material W can be transferred and cut according to this control signal.

According to this cutting method, as shown in FIG.
If the length B of the plate material W is measured in advance and the error in this plate material W is C, then when dividing the plate material W into n equal parts by the dimension b, the error in the b dimension can be c/n, and the The length b of the plate material can be kept well within the tolerance range. Further, the amount of trimming is not required, the amount of scrap can be reduced, loss of the plate material W can be prevented, cutting can be performed with a high yield, and all the material can be used as a product without generating scrap.

FIG. 4 shows a flowchart of a cutting method using such an automatic cutting device. In the figure, first, for example, the plate material W is held, the origin is corrected, and the allowable accuracy error is input, and then the length of the plate material W is measured. Next, it is compared and judged whether it is within the allowable error range or not, and if the error determined based on the length measurement is within the allowable error range and the judgment result is YES, it will be cut into n equal parts.

In addition, if the error is outside the tolerance, that is, the fourth
In the figure, if the above judgment result is NO, a signal is issued to move and cut the plate material W by dimensions b instead of b ± c/n as described above, for example. Then, it is further determined whether the out-of-tolerance error is positive or not, and when this error value is positive and the judgment result is YES, the plate material W is cut into n+1 plates, that is, the plate material W is b
Each size is cut n times and the n+1th board is scrapped, but the above error value is negative and the judgment result is
When NO, the plate material W is cut into n plates, that is, the plate material W is cut n-1 times by dimension b, and the last n-th plate becomes scrap.
