 Conventionally, a laser machine for uniaxial material movement and uniaxial light movement is equipped with a third scrap box that receives scraps and dust generated during processing. This scrap box is generally configured with a long span in the direction of light movement, and is generally made without holes or gaps so that scrap, dust, etc., will not fall out. In some cases, scrap processing is performed using chip conveyors instead of scrap boxes.

[0003]

[Problems to be solved by the device]

 By the way, the scrap box in the above-mentioned laser beam machine has the following problems because the scrap box is rectangular.

(1) One operator cannot carry the scrap box due to its heavy weight.

(2) The maintenance space must be wide enough for taking out the scrap box.

(3) Sufficient strength against heat deformation, weight deformation, etc. is required.

(4) When laser cutting the work while cooling it with water, the water accumulates in the scrap box and becomes heavy, making it difficult to carry.

[0008] Further, the type of scrap processing using the chip conveyor has a problem of cost up.

In order to solve the above problems, an object of the present invention is to provide a scrap processing apparatus in a laser processing machine in which the weight of the scrap box is reduced, the maintenance space is reduced, and water is not accumulated in the scrap box. Especially.

[0010]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a scrap processing device in a laser processing machine with uniaxial material movement and uniaxial light movement, and provides a plurality of scrap boxes for receiving scrap generated during processing in the optical movement direction. In addition to being installed separately, each scrap box was provided so that it could be carried out individually to configure scrap processing in the laser processing machine.

In the scrap processing apparatus of the laser beam machine, it is desirable that a drain hole be provided at the bottom of each scrap box and a heat-resistant member be laid on the entire bottom surface.

[0012]

[Action]

 By adopting the scrap processing device in the laser processing machine of the present invention, a plurality of scrap boxes are provided in the light moving direction, and scraps and dust generated during processing are stored in this scrap box. As a result, each scrap box is small and lightweight to carry out the scrap box, so it is easy to carry out and no maintenance space is required.

Further, even when laser cutting the work while cooling with water, even if water falls into the scrap box, it will pass through the gap of the heat-resistant material and escape from the drain hole to the outside, so that water will accumulate in the scrap box and become heavy. It never happens.

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 6, the laser beam machine 1 includes an upper horizontal arm 5 which extends from the apparatus main body 3 having a laser beam generating device and a control device and which extends in the horizontal direction, although not shown. It is provided. A laser processing head 9 equipped with a laser nozzle 7 movable in the Y-axis direction (front-back direction in FIG. 6) is attached to the tip of the upper horizontal arm 5.

A horizontal work table 13 is provided on the lower frame 11 of the apparatus main body 3, and a work movement positioning device 15 for supporting the work W and moving the work W is provided on the work table 13. ing.

The work moving / positioning device 15 is provided with a carriage base 17 extending in the X-axis direction (horizontal direction in FIG. 6) on one side of the work table 13, and the carriage base 17 is mounted on the carriage base 17 in the X-axis direction. A carriage 19 that can be moved to is provided. The carriage 19 is provided with a work clamp 21 that holds one edge of the plurality of works W.

Further, a cutting plate 23 is provided on the work table 13 along the light moving direction, and a scrap guide 25 for guiding scrap or dust is provided below the cutting plate 23. . In the lower frame 11, there is provided a scrap processing device 29 including a plurality of scrap boxes 27a and 27b for storing scraps or dust guided by the scrap guide 25 in stages. The reference numeral 31 is a door for taking out the scrap boxes 27a and 27b.

Next, the scrap processing device 29, which is the main part of the present invention, will be described in more detail.

Referring to FIG. 1, in a scrap processing device 29, the scrap boxes 27a and 27b are housed in a scrap box receiver 33, and the scrap box receiver 33 has a U-shaped cross section and is provided with a stepwise height difference. It is configured. That is, the scrap box 27a is housed in the lower part, the scrap box 27b is housed in the higher part, and when the scrap box 27b is pulled out, the step does not come into contact with the scrap box 27a housed in the lower part. Has become. Wheels 35 are provided on the lower surface of the scrap box receiver 33 to facilitate the pulling out of the scrap box receiver 33.

Further, a plurality of drain holes 37 are formed at the bottoms of the scrap boxes 27a and 27b, and a refractory brick, for example, is laid as a heat-resistant member 39 on the entire bottoms of the scrap boxes 27a and 27b. .

With the above-described configuration, as to its operation, referring to FIGS. 2 to 5, first, as shown in FIG. 2, one edge of the work W is clamped by the work clamp 21 provided in the carriage 19. , The work W is moved in the X-axis direction, and the assist gas is ejected together with the laser beam from the laser nozzle 7 provided in the laser processing head 9 to perform a desired laser processing. Scrap W _S and the dust generated at the time of laser processing falls under missing mosquitoes Tsu computing plate 23.

The scrap W _S and the dust that have fallen out are stored in the scrap box 27a or 27b as shown in FIG.

[0024] Once the scrap W _S and dust of a predetermined amount to the scrap box 27a or the 27b is housed, as shown in FIG. 4, withdrawing the scrap box received 33 by opening the door 31. Then, as shown in FIG. 5, the scrap box 27a is lifted as it is and carried out to a predetermined disposal place. When removing the scrap box 27b, pull it out, bring it forward, and then lift it out.

As described above, by dividing the scrap boxes 27a and 27b, the weight to be carried at one time can be reduced, and even one person can carry out the work, and the scrap box receiver 33 can be pulled out by half of the total maintenance work. Space can be reduced. Further, since the scrap boxes 27a and 27b are small in size, strength is not required so much and the weight can be reduced.

Further, even when the laser cutting is performed while cooling the work W with water, even if the water falls along with the scrap W _S and enters the scrap boxes 27a and 27b, the work W permeates into the gaps of the refractory bricks which are the heat resistant members 39. The water is drained through the drain hole 37 to the outside of the scrap boxes 27a and 27b. Therefore, water does not accumulate in the scrap boxes 27a and 27b and does not become heavy, so that the carrying work can be easily performed.

It should be noted that the present invention is not limited to the above-described embodiments, but can be implemented in other modes by making appropriate changes. For example, although the number of the scrap boxes 27a and 27b is two in this embodiment, the number is not limited to this, and it is also possible to use three or more. Further, although the scrap boxes 27a and 27b are provided in stages in this embodiment, it is also possible to open and close the sides of the scrap box receivers in parallel to take out the scrap boxes from the side, and further, the scrap box receivers. It is also possible to open the scrap box in the longitudinal direction and take out the respective scrap boxes from the front and back.
