Abstract

PURPOSE:To surely discharge a cut piece by connecting base metal with the cut piece on a plane and forming constitution so that both are not overlapped each other on a laser beam cutting machine. CONSTITUTION:In the laser beam cutting machine, material (base metal) 1 and the cut piece 2 on work receivers 4 are brought into contact with each other on the cut surface by the movement of a clamp 3 and moved toward the position of a discharge guide 6 and a discharge guide 8 is provided on the position set under double as thick as the base metal 1 on the base metal 1 and the cut piece 2. Consequently, even if the base metal 1 and the cut piece 2 are moved by the clamp 3, both of these are not overlapped each other and can be moved to the discharge position and the cut piece discharge is stabilized and a danger of an operator is eliminated and the laser beam cutting machine can be stably operated for a long time.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a laser processing machine, a laser compound processing machine,
The present invention relates to a laser processing cut piece discharge device.

[Prior art] In a conventional laser processing machine, a clamp that holds a material (base material) moves in the X-axis or Y-axis direction immediately after laser processing is completed, and contacts the cut pieces of the material at the cutting surface. However, it was moved to the ejection position and ejected.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technology, due to bending and warpage of the material, it is not possible to move the cut pieces of the material so that they come into contact with each other at the cut surface, and the two pieces overlap. It is often necessary to temporarily stop the machine during processing and manually discharge the waste, which poses problems such as danger, lower operating rates, and the inability to operate stably for long periods of time.

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and an object of the present invention is to provide a laser-processed cut piece discharging device that can reliably discharge cut pieces.

[Means for Solving the Problems] The laser processing cut piece discharge device of the present invention has a material (base material)
Therefore, the range in which the material (base material) and the cut pieces are connected on a plane and the material (base material) and the cut pieces do not overlap during the time from just before the end of the specified processing until the end of discharge. It is characterized by having a mechanism that regulates the

[Function] According to the present invention, the material (base material) and the cut pieces are connected on a plane during the period from just before the predetermined processing of the material (base metal) and the cut pieces ends until the discharge is finished. In addition, by having a mechanism that restricts the material (base material) and cut pieces to a range where they do not overlap, it becomes possible to easily move the material (base metal) and cut pieces reliably on the cutting surface. It is not necessary to temporarily stop the machine in operation for discharging cut pieces, eliminating the danger of discharging work, and enabling stable operation for a long time.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows an example in which the laser-processed cut piece discharging device of the present invention operates immediately before the end of laser processing. The material (base material) 1 on the workpiece receiver 4 and the cut piece 2 come into contact with each other at the cut surfaces due to the movement of the clamp filter, and move toward the position of the discharge guide 6. However, because the discharge guide 8 is installed above the material 1 and the cut piece 2 at a position set to be less than twice the thickness of the material 1, even if it is moved by the clamp 6, the material 1 The cut pieces 2 can be moved to the discharge position without overlapping. The discharge guide 8 is fixed to a guide mounting block 9 and engaged with a guide shaft 17 guided by a bearing 10, and is connected by a connecting plate 12.
It can slide vertically by driving the air cylinder 14 fixed to the air cylinder mounting plate 16. The reason why the ejection guide 8 is moved up and down is that the laser head 7 moves upward to move the material 1 immediately after the laser processing is completed, and when the laser head is attached in the same manner as the laser head attachment part, it is This is due to the fact that it is difficult to maintain the position of the discharge guide 8 at a position that is less than double the position. FIG. 2 shows an example of connecting a material (base material) and a cut piece on a plane. A material (base material) 1 and a cut piece 2 are connected by a discharge guide 8 (rod-shaped). The discharge guide 8 is desirably made of a material with lower hardness than the material, and its shape may be a rod-like, plate-like two-rotator, or the like. The reason why the discharge guides 8 are provided on the left and right sides of the laser head is to enable the laser processing to be completed at any position. Third
The figure shows a double sheet ejection failure according to the conventional technology.
Material 1 and cut piece 2 are placed under 1 and become two layers, and material 1 and cut piece 2 are
It cannot be touched at the cutting surface and cannot be moved to the discharge position. The material 1 is held by a clamp 6. FIG. 4 shows the completion of discharge in the present invention. The cut pieces 2 that have moved in contact with the cut surface of the material 1 are moved by the discharge guide 8.
It can be moved to the ejection position without stacking two sheets, and the ejection plate 6
It slides down and is ejected.

[Effects of the Invention] As explained above, the laser-processed cut piece discharging device of the present invention, in a laser processing machine, can process a material (base material) from just before a predetermined process is completed to when discharging is completed.
By having a mechanism that restricts the material (base material) and cut pieces to a range where they do not overlap, it is possible to easily move them reliably on the cutting surface, stabilizing the discharge of cut pieces, and eliminating danger to workers. This has the effect of enabling stable operation for long periods of time.
