On the other hand, a workpiece transfer supporting member for movably supporting the workpiece during the transfer of the workpiece is provided, and the rotation center of the rotating member is provided at a position approximately half the distance.

Therefore, when loading or unloading a work on the work table, the work is transferred by rotating the rotating member and positioning the support member so as to project above the first work supporting member during the work transfer. At this time, it is carried in and out while being supported on the supporting member.

When the workpiece is subjected to the heat cutting process, the rotating member is rotated to position the upper surface of the second work supporting member flush with the upper surface of the first work supporting member, whereby the first work is performed. The work is supported by the second work support member, and the work is thermally cut.

Since the center of rotation of the rotating member is provided at a position approximately half the distance between the first work supporting members, the product subjected to the heat cutting is supported by the first and second work supporting members and is erected. It will never go up. Therefore, since the product does not collide with the thermal cutting head,
It does not damage the product or the thermal cutting head.

According to a second aspect of the present invention, there is provided a work table for a thermal cutting machine according to the first aspect of the present invention, which is the work table for the thermal cutting machine according to the first aspect, wherein the second workpiece support member provided on the rotating member and the workpiece transfer support member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Since a thermal cutting machine such as a laser processing machine or a plasma processing machine is known, the description of the entire structure will be omitted, and the main components will be described.

Referring to FIG. 1, a work table 1 of a laser beam machine is provided with a base 3 which is movable in a direction orthogonal to the plane of the drawing in FIG. 1, for example.
1, a plurality of first work supporting members 5 such as a sword mountain and a skid are fixedly erected on the upper side for supporting the work W at the time of laser processing at appropriate intervals A in the left-right direction. A rotary member 7 is mounted on a rotatable shaft 9 between the first work support members 5.

As shown in FIG. 3, for example, the two rotary shafts 9 in FIG. 1 have sprockets 11A and 1A.
1B is installed and these sprockets 11A, 11
A chain 13 is wound around B. One end of the chain 13 is fixed, and the other end of the chain 13 is attached to the tip of a piston rod 17 mounted on the cylinder 15.

With the above structure, the cylinder 15 is actuated and the piston rod 17 is expanded and contracted.
As the sprockets 11A and 11B are rotated, the respective rotary shafts 9 are synchronously rotated. By rotating each of the rotating shafts 9, the rotating member 7 is also rotated in the same direction.

Referring again to FIG. 1, one of the rotating members 7 has a supporting member 19 for transferring a work such as a ball.
Is provided, and at the position separated from the other of the rotating member 7 by the angle θ of 90 degrees to 180 degrees with respect to the support member 19 at the time of transferring the work, the work W is placed at the time of performing the laser processing on the work W. A second work support member 21 such as a supporting sword and a supporting skid is provided.

In the state of FIG. 1, the distance between the first work supporting members 5 is A and the height of the first work supporting members 5 is 2B. And if the position of the rotating shaft 9 is B,
The distance from the rotary shaft 9 to the tip of the support member 19 during work transfer is (B + α), and the support member 1 during work transfer is rotated by rotating the rotary shaft 9 to rotate the rotary member 7.
9 is in an upward state, and the tip of the supporting member 19 is projected from the pass line (the upper surface of the first work supporting member 5) by α when the work is transferred.

In this state, the work W is carried on the work table 1 while being supported on the support member 19 during the work transfer.

When the rotary shaft 9 is rotated by an angle θ, as shown in FIG.
1 is in a state of facing up. In this state, the work W is supported by the first and second work supporting members 5 and 21, and the laser processing head 23 is moved leftward in FIG. 2, whereby the product G is cut from the work W. .

As shown in FIG. 2, the cut product G is supported by the first and second work supporting members 5 and 21 to prevent the product G from rising, so that the product G is a laser. The laser beam does not collide with the processing head 23, and damage to the laser processing head 23 and the product G can be reduced. That is, by narrowing the interval (pitch) for supporting the work W during laser processing to 1/2 A,
Preventing the rising of product G, product G, laser processing head 2
The damage to 3 can be reduced.

In the state where the second work supporting member 21 is directed upward as shown in FIG. 2, the support member 19 at the time of transferring the work is from 90 degrees to 18 degrees with respect to the second work supporting member 21.
Since it is inclined by the angle θ within the range of 0 degree, the work W
The dust generated during the laser processing is sucked by a suction device such as a suction duct provided below the base 3 so that the gas flow passing to the lower side of the work W does not scatter or soar, and the dust is sucked. The removal can be performed efficiently.

The present invention is not limited to the above-described embodiment, but can be embodied in other modes by making appropriate changes. In the example of the present embodiment, the first and second work supporting members 5 and 21 are shown as an example of Kenzan, but a mountain-shaped skid or the like may be used. Further, although a ball is shown as an example of the work supporting member 19 during work transfer, a roller or the like may be used. The cylinder 15, the chain 13, and the sprockets 11A and 11B are shown as examples of the rotary drive system for rotating the rotary shaft 9, but the cylinder, rack and pinion, rotary actuator, cylinder, link structure, motor drive or worm, worm wheel. And so on.

Further, the rotary shaft 9 and the first work supporting member 5
May be parallel or may be arranged in an orthogonal state. The angle θ of the rotating member 7 may be any angle as long as it is within the range of 90 degrees to 180 degrees, but an angle of about 120 degrees is the most desirable for efficiently sucking dust in the suction duct. Is.

[0027]

As can be understood from the above-described embodiments, according to the invention of claim 1, when the work is carried in and out of the work table, the rotating member is rotated to transfer the work. By positioning the time support member so as to project upward from the first work support member, the work is supported on the work support member during the work transfer and is carried in and out.

When the work is subjected to the heat cutting process, the rotating member is rotated to position the upper surface of the second work supporting member flush with the upper surface of the first work supporting member, whereby the first work is performed. The second work is supported and the work is thermally cut.

Since the center of rotation of the rotating member is provided at a position approximately half the distance between the first work supporting members, the heat-cut processed product is supported by the first and second work supporting members and is erected. There will be no climbing. Thus, since the product does not collide with the thermal cutting head, damage to the product or the thermal cutting head can be reduced.

According to the second aspect of the present invention, the rotary member is rotated so that the second work supporting member faces upward, the work is supported by the first and second work supporting members, and the work is subjected to thermal cutting. When the work is transferred, the support member is tilted in the range of 90 to 180 degrees from the vertical state when the work is transferred. Therefore, the dust generated during the heat cutting process of the work is like a suction duct provided below the work table. The gas flow sucked by the suction device and passed to the lower side of the work does not scatter or soar, and the dust can be sucked and removed efficiently.
