The carriage base 13 is provided with an X-axis carriage 15 which can be moved and positioned in the X-axis direction by an X-axis moving mechanism (not shown). The X-axis carriage 15 has a plurality of (here, four) plate clampers 17.
A, 17B, 17C, 17D are provided at predetermined positions, and the plate material W is clamped using plate material clampers 17A, 17B, 17C, 17D suitable for the size of the plate material W.

C, 17D are provided with a scale 16 as an example of a clamper position detecting means.
Even if 7B, 17C, 17D is moved, the position is always N
The information is transmitted to the C device 18.

For example, size 2500 mm × 1270 m
m of the plate material Wa, the plate material clamper 17D is the plate material clamper 1
If it is within 2500 mm from 7A, it is clamped using all the plate clampers 17A, 17B, 17C, 17D, so that the size can be grasped from the position of the plate clamper 17D.

The size of the plate material Wb in FIG. 1 is clamped by the plate material clampers 17A, 17B, 17C and not clamped by the plate material clamper 17D, so that the size of the plate material Wb can be grasped.

Similarly, the size of the plate material Wc in FIG. 1 is clamped by the plate material clampers 17A and 17B, but not clamped by the plate material clampers 17C and 17D, so that the size of the plate material Wc can be grasped. .

An NC device 1 for controlling the punch / laser machine 1 is located near the punch / laser machine 1.
8 is provided to control the X-axis moving mechanism and the Y-axis moving mechanism, and to detect the position of each plate material clamper 17A, 17B, 17C, 17D based on a signal from the scale 16 described above.

With the above configuration, when performing the punching process, the plate material W is clamped to the plate material
The X-axis carriage 15 is moved and positioned in the X-axis direction in accordance with a command from the C device 18, and the carriage base 13 is moved and positioned in the Y-axis direction. Punching is performed in cooperation with the punch and die.

On the other hand, when performing laser machining, the X-axis carriage 15 is moved and positioned in the X-axis direction by the command of the NC device 18, and the carriage base 13 is moved and positioned in the Y-axis direction. The processing position of W is positioned at the laser processing position L, and laser processing is performed by irradiating laser light LB from the laser processing head.

Referring to FIGS. 2 and 3, the above-mentioned plate clamper 17 is shown. Each plate material clamper 17A,
17B, 17C and 17D are a fixed lower clamp jaw 19L and a pin 2 with respect to the lower clamp jaw 19L.
Upper clamp jaw 1 that opens and closes vertically about 1
9U. A cylinder 23 is provided at the rear end (the right end in FIGS. 2 and 3) of the lower clamp jaw 19L. The rear end of the upper clamp jaw 19U is provided at the lower end of the piston rod 25 of the cylinder 23. Pin 2

Are connected to the NC device 18.

With the above configuration, the combined punch / laser machine 1
After deciding the origin of the plate material W carried into the apparatus, all the plate material clampers 17A, 17B, 17C and 17D are clamped. At this time, the plate clamps 17A, 17B,... Which actually clamp the plate W do not become zero because the plate thickness sensor 29 measures the plate thickness T of the clamped plate W. At 17, since the measured plate thickness becomes zero, it is easy to know which plate clamper 17 is clamping the plate W, and the size of the plate W can be known from the position of the clamped plate clamper 17. Further, the plate thickness T of the plate material W is also measured at the same time.

Next, the operation of determining the shaft speed and starting machining will be described.

Referring to FIG. 4, the plate material W is carried into the punch / laser machine 1 and set (step S1), and the plate material W is clamped (step S2). Information on which plate clamper 17 has clamped the plate W is obtained (step S3), and the size and thickness of the loaded plate W are measured (step S4). When the size and the thickness of the plate W are measured, the NC device 18 determines an axial speed at which the plate W is positioned (step S5).

For example, referring to FIG. 5, when the two plate clampers 17A and 17B are clamped and the other plate clampers 17C and 17D are not used, the thickness sensor 29 of the plate clampers 17A and 17B is used. In the case of a thin plate having a plate thickness of 0.5 to 3.0 mm, the axial speed is high. At this time, the plate clampers 17C, 17C
The plate thickness sensor 29 of D indicates zero, indicating that the plate material W is not clamped.

In the case of a middle plate having a plate thickness of 3.1 mm to 5.9 mm, the shaft speed is a medium speed. Alternatively, a sheet material W having a size to be clamped by the four sheet material clampers 17A, 17B, 17C, and 17D,
In the case where a plate thickness of 6.0 mm or more is measured according to 9, the shaft speed becomes low. When the shaft speed is determined in this way, the plate material W is moved and positioned based on the shaft speed to start machining (step S6).

From the above results, even when the size and thickness of the plate material W change, the plate material W can be moved and positioned at an axial speed suitable for the size and the thickness. Thereby, automation and unmanned processing can be achieved.

Further, when the weight of the plate W becomes excessive, the positioning accuracy of the plate W is improved by automatically lowering the shaft speed. Therefore, regardless of the size or the thickness of the plate W to be used. In addition, the processing accuracy can be improved.

Next, the X axis, Y
A method of automatically applying an appropriate override to the axis feed speed to stabilize the processing state of the plate material and prevent breakage of the plate material and the processing machine will be described.

Referring to FIG. 6, when starting (Step SS), a GO6 command is issued (Step S11). The GO6 command is a program for instructing the sheet thickness and the material, and instructs that the sheet thickness is 1.5 mm, for example, as in “GO6A1.5B0:”.

It is determined whether or not the override is to be performed based on the value of "A" (step S12). For example,
If “A” is 1.0 or less, or 4.5 or more, an override flag is set to override (step S13), and if “A” is 1.1 to 4.4, no override is performed.

The RMC ladder receives the flag of the override flag (step S14), and if the flag is on, issues an override F4 command (step S14).
15), NC device 1 for controlling punch / laser multifunction device 1
8 applies an override to the axis feed speed. On the other hand, if the flag is off, the process ends without issuing an override command (step SE).

From the above results, since the movement and positioning are performed at an axial feed speed suitable for the thickness of the plate material, the backlash of the plate material during processing can be reduced, and the breakage of the plate material and the breakage of the processing machine can be reduced. Can be prevented. Further, it is possible to prevent an operation error of the worker.

It should be noted that the present invention is not limited to the above-described embodiment of the present invention, but by making appropriate changes,
It can be implemented in other aspects. That is, in the above-described embodiment of the present invention, the determination as to whether or not to apply the override is made based on the plate thickness of the plate material. The determination may be made based on the size. In this case, “G06 A2.3 B1 I1
200. J950. : ", It is necessary to input not only the plate thickness but also the X and Y dimensions.

Further, in the above-described embodiment of the present invention, a punch / laser multifunction machine has been described as a plate material processing machine. In addition, the plate material is clamped to move and position in one or two axes. The present invention can also be applied to a plate material processing machine such as a turret punch press or a laser processing machine for performing processing.

The size of the plate can be automatically measured from the clamper.

In the plate processing machine according to the fourth aspect of the present invention, the size of the plate is detected by automatically detecting the position of the clamper by the clamper position detecting means provided on the plurality of clampers for clamping the plate, and provided on the clamper. The sheet thickness is automatically measured by the sheet thickness measuring means, and the axis feed speed determining means determines the optimum axis feed rate according to the size and / or the sheet thickness of the sheet material, performs the axis feed, and positions the sheet material. Since the processing is performed by the plate material processing machine, it is possible to prevent the plate material from being damaged and the plate material processing machine from being damaged. In addition, since movement and positioning are performed at an axial feed speed suitable for the plate material, high-precision processing can be performed.

In the plate processing machine according to the fifth aspect of the present invention, the plate thickness measuring sensor measures the plate thickness from the difference in the rotation angle or height difference between the upper clamp jaw and the lower clamp jaw when the plate is clamped.
