Next, for example, the laser beam machine 1 performs laser processing on the workpiece W carried on the workpiece support member 63 of the workpiece table 13 shown in FIG. To explain, first, as shown in FIG. 4A, when the work W loaded is lifted up to the support position of the lift end by the lift cylinder 57, it is supported on the work support member 63. And clamped by the work clamp 41. In this state, when a laser beam is irradiated toward the workpiece W from the laser processing head 3H that is movable in the X, Y, and Z axis directions provided in the laser processing machine 3, products G having various shapes are cut and processed. After the product G has been cut, if the vibration device 53 is operated as necessary, the product G is reliably separated from the workpiece W and supported on the workpiece support member 63.
[0040]
Next, when the lifting cylinder 57 is operated to lower the work table main body 55 to the unloading position at the lower end as shown in FIG. 4B, the product G is supported on the work supporting member 63 and the remaining portion is left. The material Ws remains in the state of being clamped by the work clamp 41. When the drive motor 65 is driven in this state, the work support member 63 is rotated as shown by the arrow in FIG. 1, and the product G is transferred from the work support member 63 onto the carry-out conveyor 77 shown in FIG. Reprinted.
[0041]
When the product G is transferred onto the carry-out conveyor 77, when the drive motor 91 is driven, the roller 71 is rotated and guided by the guide rail 27 shown in FIG. It is moved from the position to the position of the solid line and stopped. When the drive motor 83 is driven in this state, the carry-out conveyor 77 travels and rotates, so that the product G is transferred from the carry-out conveyor 77 to the carry-out conveyor 29 and then carried out to the outside.
[0042]
As shown in FIG. 4B, the remaining material (skeleton) Ws clamped by the work clamp 41 is unclamped from the work clamp 41 and rides on the carry-out table 15 and is further sent to the shearing machine 17. The remaining material Ws is finely cut by the shearing machine 17, and then stored in the scrap box 19 and carried outside.
[0043]
Thus, the product G and the remaining material Ws are easily separated in a short time and can be easily carried out regardless of the shape and size of the product. Moreover, it can be applied not only to coils but also to sketch materials and standard materials. Since the work clamp 41 is provided with the vibration device 53, the product G can be easily separated from the work W by applying vibration to the work clamp 41 by the operation of the vibration device 53.
[0044]
In addition, this invention is not limited to the example of embodiment mentioned above, It can implement in another aspect by making an appropriate change.
