Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser beam machine for vertically suspending and processing a work and carrying the work in and out.

[0002]

2. Description of the Related Art Conventionally, when a work is cut by a laser beam machine, the work is placed on a table, which is called a sword mountain, in which support bases are arranged in a grid pattern. When such a laser processing machine is used by incorporating it into the FMS line, a plate material which is a work is set on a horizontally installed table by a carry-in / carry-out machine, and further taken out from the table when the processing is completed. .

At this time, an uncut portion called a micro joint is formed on the cut work, the whole work is lowered from the table so as not to fall from the work, and then the uncut portion is separated by shaking the work. I was taking out the cut.

[0004]

In the conventional laser processing machine, when a work which is a plate material is cut and then taken out from the table, the work is unprocessed because it is processed by laser. Compared with this, the strength may be reduced, or the part that holds the work may be cut depending on the cutting shape, and it was not possible to carry out the work corresponding to all cutting programs. Also, there is a carry-out machine forcibly scooping the work from below with a fork-like work, but it was necessary to move the fork up and down, which was an extremely large-scale device.

An object of the present invention is to solve the above-mentioned conventional problems and to provide a laser beam machine for facilitating the unloading of a work after cutting.

[0006]

In order to achieve the above object, a laser beam machine according to a first aspect of the present invention carries in a work provided with an upper holding device for vertically holding a work which is a plate material. A laser torch is provided so as to be movable on a vertical plane in order to process a workpiece held vertically by the carry-out device, and laser processing is performed while the work is held in the carry-in / carry-out device. .

The laser beam machine according to the second aspect of the present invention includes an upper holding device for vertically holding the plate material and a plate material loading / unloading device provided with a lower holding device for pulling the work from below. , A laser torch is provided so as to be movable on a vertical plane in order to process a plate material held vertically,
The laser processing is performed while the work is held in the carry-in / carry-out device.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The laser beam machine according to the first aspect of the present invention performs laser beam machining while holding a work, which is a plate material, in the carry-in / carry-out device, and the work is still hung by the upper holding device even after cutting. , Has a function of carrying out the work from the laser processing machine as it is.

Further, in the laser beam machine according to the second aspect of the invention, the upper holding device suspends the work, and the lower holding device firmly fixes the work to be pulled downward, and holds the soft work such as a thin plate in the carry-in / carry-out device. The laser processing is performed as it is, and since the work is suspended by the upper holding device even after cutting and is held by the lower holding device, the work is carried out from the laser processing machine as it is.

(Embodiment 1) Hereinafter, Embodiment 1 of the present invention will be described in detail with reference to FIGS.

In FIG. 1, a laser beam output from a laser oscillator 1 is guided to a processing point through a retractable laser duct 2 of X axis, Y axis and Z axis. At this time, the laser light is refracted by 90 degrees in the Y-axis direction and the Z-axis direction by the mirror 3. At the processing point, the laser light is focused by the condenser lens housed in the laser torch 4, and the work 5 is cut by the thermal energy of the condensed laser light.
The position of the mirror 3 for refracting the laser beam and the laser output are controlled by a numerical control device (not shown), and by issuing a machining program to the numerical control device, the work 5 can be shaped into an arbitrary shape. Disconnect. The mirror 3 is moved by the X-axis slider 6 and the Y-axis slider 7. The X-axis slider 6 and the Y-axis slider 7 are composed of a ball screw and a hollow motor, and the rotation of the motor causes the mirror to move in the X-axis and Y-axis directions. Further, the X axis is the direction in which laser light is emitted from the laser oscillator, the Y axis is the vertical direction, and the Z axis is the direction perpendicular to the X and Y axes. The upper holding device 8 that suspends the work 5 is provided in a carry-in / carry-out device 9 that carries out and carries in the work 5 which is a plate material.
Moves to the laser processing position. While the work 5 is still held by the carry-in / carry-out device 9, the laser torch 4 moves on the X- and Y-axis planes, which are vertical planes, by the above-mentioned mechanism to irradiate a laser beam for cutting.

Since a small cut product produced by laser cutting may be dropped and taken out regardless of the micro joint, the cut cut product is slid and taken out by the work receiving slope 10 so as not to be deformed by the impact due to the drop. It is a thing. Further, the laser shielding plate 11 is provided so that the laser light penetrating the work 5 does not escape to the rear of the processing machine.

(Second Embodiment) Next, a laser processing machine according to a second invention will be described with reference to FIGS.

Also in the second embodiment, similarly to the first embodiment, the work 5 is suspended from the upper holding device 8 installed in the plate material loading / unloading device 9. Then, in the case of a thick plate, the work 5 may be suspended by the upper holding device 8,
Since the thin plate has low strength, the work 5 may not be stable at the time of cutting. In the second embodiment, in order to deal with this, the work 5 at the time of cutting is made more stable by pulling it downward by the lower holding device 12 installed in the carry-in / carry-out device 9.

[0015]

As described above, when the laser beam machine according to the first aspect of the present invention is incorporated in the FMS line, the work can be carried out while the work is held in the carry-in / carry-out device, and the work can be carried out in a state of being suspended vertically. Therefore, even after the completion of cutting, it is in a state of being suspended by the upper holding device of the carry-in / carry-out device, and the work after completion can be easily taken out, whereby the laser processing machine can be easily incorporated in the FMS line. It has an excellent effect.

Further, the laser processing machine of the second invention, when incorporated in an FMS line, can process a soft work such as a thin plate while holding it in the carry-in / carry-out device, and the work is hung vertically. Therefore, even after the completion of cutting, it is in a state of being hung by the upper and lower holding devices of the carry-in / carry-out device, and the work after completion can be easily taken out, whereby the laser processing machine can be easily incorporated in the FMS line. It has an excellent effect.
