The present invention relates to a display device of a cutting machine that constantly displays the required length of

(Prior Art) Conventionally, for example, in a horizontal band saw machine as a cutting machine, cutting is performed while feeding a large number of cutting pieces from one work piece at a constant length. In recent years, high-mix low-volume production has become common. That is, there are many cases where many products having different lengths are obtained from the same work.

(Problems to be solved by the invention) By the way, when a large number of products with different lengths are taken from the same conventional work described above, the worker cannot display the required length of the work on the display device. Since the required length of the work piece is calculated each time and a large number of pieces are cut into the required product length by the cutting machine, the work of the worker is very troublesome and the burden on the worker is heavy.

In addition, sometimes a work shorter than the required length is cut and the required product cannot be processed.

The object of the present invention is to improve the above-mentioned problems by making it possible to display the required length of the work on the display device, reduce the burden on the operator, and avoid cutting the work shorter than the required length. To provide a display device for the cutting machine.

It is a cutting machine that feeds the material length by length and continuously cuts multiple times.The input device that inputs the length of the work and the number of cuts to be cut, the preset cutting allowance, and the remaining material length are set. Arithmetic processing for arithmetically processing the required length by taking in a memory to be stored, the length of the work input from the input device, the number of times of cutting, and the cutting allowance and the residual material length stored in advance in the memory. A display device of a cutting machine is configured by including a device and a display device that displays a required length that is arithmetically processed by the arithmetic processing device.

(Operation) By adopting the display device of the cutting machine of the present invention, when the work is cut by the cutting machine, the cutting allowance and the remaining material length are stored in the memory in advance, and the length of the work from the input device, When the number of times of cutting is input, the arithmetic processing unit calculates the necessary length based on the cutting margin from the memory, the length of the remaining material, the length of the work from the input device, and the number of times of cutting.

Since the necessary length calculated by this arithmetic processing unit is displayed on the display unit, the operator may check the display and check the length of the work. Thus, the work load on the worker is reduced, and the work that is shorter than the required length is cut off.
