2. Description of the Related Art Generally, as shown in FIG. 4, a cutting water jet apparatus 1 is operated by a high water pressure apparatus 2 at 500 Kg / c.
Water with a high water pressure of m ^{2 to} 4000 kg / cm ² can be jetted from a jet nozzle 3 connected to the high water pressure device 2 via a pipe 4. The jet nozzle 3 is provided in a drive mechanism 5 having a horizontal axis and a vertical axis so that the jet nozzle 3 can be moved vertically and horizontally. The drive mechanism 5 is mounted on a biaxial or triaxial robot 7. The high water pressure water jetted from the jet nozzle 3 is discharged from the drainage device to general sewage, or is supplied to the high water pressure device 2 again by the circulation device.

The two-axis or three-axis robot 7 is shown in FIG.
As shown by the imaginary line, an object 9 to be cut such as wood, copper plate, plastic plate, rubber plate, cloth, etc. is placed and cut into a desired shape by the high-pressure water ejected from the ejection nozzle 3. The drive mechanism 5 is controlled by a controller (not shown).

[0004]

However, in the conventional water jet device for cutting, when cutting a relatively hard workpiece 9 such as wood, copper plate, plastic plate, etc., the cutting is accurate and has a good finish. Although the surface can be obtained, a relatively soft object to be cut 9 such as a rubber plate, a cloth, a plastic plate, etc.
When cutting a large-shaped or large-shaped cut object 9, the soft cut object 9 may fall into a drain hole or the like during cutting, or the cut object 9 larger than the end of the biaxial or triaxial robot 7 may be cut. There was a risk of falling. In addition, the cut surface of the relatively soft object 9 or the large object 9 may be defective.

It is an object of the present invention to cut a relatively soft object to be cut into a drainage hole or the like, or a large object to be cut at the end of a biaxial or triaxial robot. (EN) A jig for placing an object to be cut of a water jet device for cutting, which is capable of obtaining a cut surface which is accurate and has a good finish without a risk of falling from a portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 respectively show an embodiment of a cutting object placing jig of a cutting water jet device according to the present invention. Axis or 3-axis robot 7 (in this embodiment, 3-axis robot, XYZ
A traverser), and a support member 13 for supporting the object 9 to be cut provided on the base 12.

The base 12 is formed of a flat box body,
In the present embodiment, the height is about 10 mm, and the flat box body has a size of 2 m square or 1.5 m x 10 m. However, the size is not limited to this, and the size is appropriately determined. can do. Water holes 12b are formed in the bottom plate 12a of the base 12.

The support member 13 for the object 9 to be cut is formed of a plurality of ridges. This support member 13 is shown in FIG.
In the embodiment shown in (a), a net 13a made of metal such as stainless steel having a 1 mm square mesh is attached to a base 12 made of a box. This metal net 13
When the support member 13 is formed of a, the base 12 may be formed of a frame.

In the embodiment shown in FIG. 2, the ridge 13b made of a stainless plate is fixed to the base 12 in the upright state to form the support member 13. The ridge 13b may be formed of a wire or the like.

Further, as shown in FIG. 1B, a member 15 having water permeability is inserted in the base 12 of the object mounting jig 11 in a state of abutting against the lower end of the metal net 13a.
The water-permeable member 15 is formed of a fibrous material 15a such as felt or fiber, and sand or synthetic resin powder 15b. When the member 15 having water permeability is formed of sand or synthetic resin powder 15b, the base 12 is used.
It is necessary to solidify the bottom plate 12a so that it does not fall off from the water holes 12b formed in the bottom plate 12a. A member 1 having water permeability
5 can be formed from a block having water permeability, which is obtained by solidifying powder of sand or synthetic resin with resin.

In this embodiment, a fibrous substance 15a such as felt or fiber is placed on the bottom plate 12a of the substrate 12, and then sand or synthetic resin powder 1 is placed on the fibrous substance 15a.
Since 5b is inserted, sand or synthetic resin powder 15b does not fall off from the water passage hole 12b. Further, the member 15 having water permeability may be formed only from the fibrous substance 15a such as felt or fiber, or the member 15 having water permeability may be formed only from the powder 15b of sand or synthetic resin. Further, the member 15 having water permeability may be one in which sand or synthetic resin powder 15b is wrapped with a fibrous substance 15a such as felt or fiber.

It is possible to cut the object 9 to be cut easily, quickly and accurately by ejecting the water of high water pressure. If the metal net 13a of the support member 13 is replaced after the cutting work has been performed 500 to 1000 times, the formation of a high quality cut surface can be maintained.

FIG. 3 shows a different embodiment of the present invention. The parts corresponding to those of the above-mentioned embodiment are designated by the same reference numerals, and a detailed description thereof will be omitted. A vacuum suction device 21 is attached to a pipe 23 on one side of the base body 12
Similar to the above-described embodiment except that the substrate 12 is mounted on the biaxial or triaxial robot 7,
And a supporting member 13 for the object to be cut 9 provided on the base body 12.
It has and.

Further, the non-breathable synthetic resin film 25 is arranged to cover the object 9 and the supporting member 13 while the object 9 is placed on the supporting member 13. Therefore, by covering the material 9 to be cut and the support member 13 with the synthetic resin film 25 and operating the vacuum suction device 21, a felt or a fiber such as a fiber, which is the member 15 having water permeability, inserted into the substrate 12. Substance 15a,
And air in the sand or synthetic resin powder 15b is sucked, the fibrous material 15a such as felt or fiber, and the sand or synthetic resin powder 15b, etc. are fixed, and the cut object 9 is placed on the support member 13. It is possible to prevent the fibers from moving, and to prevent the fibrous substance 15a and the sand or synthetic resin powder 15b from scattering.

Then, by controlling the drive mechanism 5 by the controller, high water pressure water is ejected from the ejection nozzle 3 similarly to the above-described embodiment, and the object 9 to be cut is simply ejected by the high water pressure ejection. It can be cut quickly and accurately.

[0022]

The above is the construction of one embodiment of the cutting object placing jig of the cutting water jet apparatus according to the present invention. According to such a construction, the cutting object placing jig is Since the base body is formed of a flat box and the support member of the cut body is formed of a metal net, the base body and the support member for the cut body provided on the base body are provided.
