Abstract

PURPOSE:To enable efficient manufacture of fine cut-out patterns by plading metallic pattern masks on sheet materials on a disc table, rotating the table, scanning a laser beam while sucking air by a vacuum pump from below and cutting out the materials. CONSTITUTION:Metallic pattern masks 10 are placed on a suitable number of sheet materials 11 and are set in the hole parts 4 of a rotary disc 3. The table 3 is rotated and while air is sucked through a suction port 5 and a suction pipe 6 by operating a vacuum pump, a laser beam 8 is moved and scanned in the radial direction of the disc. The beam 8 moves linearly in the radial direction by a prescribed distance at every one rotation of the disc. Desired cut-out patterns are thus efficiently manufactured in a large quantity. The smoke generated by the cutting out of the above-mentioned method is sucked to the outside and therefore the contamination of the mateials is obviated and the fine cutting-out is easily accomplished.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a cutout pattern in cutting out paper for dyed illustrations, etc.

Traditionally, patterns were created by manually cutting out materials for paper-cutting crafts, or attachments for the dyeing industry, but because the patterns were so detailed, the cutting process took considerable time and effort. I needed time. In addition, in recent years, cutting of fine cutout patterns has been carried out efficiently and quickly using laser beams, etc. However, smoke from the heat of the laser beams can penetrate into the gaps in the material, causing In addition, the paper or film surface is stained and the value of the product per song is extremely reduced, and there is an urgent need to solve this problem.

The present invention can solve the above problems, can quickly create high-quality fine cutout patterns, and can easily carry out cutting of fine patterns that would be impossible to do manually. .

In the present invention, a metal pattern mask plate is placed on a sheet of paper or other thin sheet material, placed on a rotary disc table, and rotated, and while vacuum suction is applied from the bottom of the material, a laser beam is directed at the center of rotation of the disc table. A cut-out pattern mask board using a laser beam, which is characterized by cutting out patterns such as letters or fine patterns on the surface by scanning along straight lines passing through it, can be used to cut out a copper plate, such as a crest, or a ladder shape. Use the cutout. A laser beam is scanned from the upper side of this metal pattern mask plate to burn out several stacked sheets of paper or film on the lower side of the mask plate in a straight cross-section from the upper layer to the lower layer. . In that case, the smoke generated from the cutting material during burning will enter the gap between the stacked materials and stain the cutting surface, so the cutting disk workbench is made into a hollow disk shape and the generated smoke is removed by a vacuum pump. , which should be removed by constant suction.

To explain the method of the present invention in more detail, as shown in FIG. Place the board (10). Next, Figure 2 (ol
, by irradiating a laser beam from the upper side of the mask plate (10),
A part of the cutout pattern (old paper located below 10a) of the mask plate CtO+ is destroyed and burned out with a hot ray to obtain a superimposed paper aυ in which a cutout pattern α force as shown in FIG. 3 is formed. Glue one end (al side) of the paper Oυ and attach a cover (13) to create stationery or a memo pad.

When carrying out the method of the present invention, it can be carried out using, for example, an apparatus as shown in FIG. That is, the cutout/cut turn forming device has a disc table (3) mounted horizontally on the upper part of the support (21) provided perpendicularly to the bottom plate (1) via a bearing rotating shaft or the like so that it can be rotated by a motor. , the table (
3j is designed to be able to rotate in the direction of the arrow, and holes (4) for inserting the paper stripping material 0υ and the mask plate 1 (11) are placed at equal intervals along the inner circumference of the upper surface of the table (3). )
A suction 11 t51 is provided on the bottom surface of the holed portion (4). An air suction pipe (6) is installed in the center of the disk table (3), and the table (S3) is connected to the table (S3) from the suction port (5) as a hollow disk table.
It is designed so that air can be sucked outward through the interior and suction tube (6).

A laser irradiation unit (7) is provided at a predetermined location on the pull-up side, and the irradiation unit (7) is arranged around the circumference of the rotary table (3). More rotating mid-up/
The mask plate 00) is moved back and forth linearly in the direction of the arrow on the line connecting the parts, so that the surface of the mask plate 00) can be uniformly scanned by the laser beam (8).

The method of the present invention will be explained in detail according to examples (a.
For example, about 8 sheets of 13-5 size cut-out and turn-forming paper (II) as shown in FIG. Alternatively, a stainless steel mask plate (10) is placed, and a plurality of the cents (for example, 16 sets) are fitted into the hole holes (4) of the 1500% diameter disc table (11) of the cutout pattern forming device shown in FIG. Set. While rotating the disc table (3) in the direction of the arrow, start the vacuum pump and suction air from the suction port (5) to move the laser irradiation part (7) from the inside to the outside. The mask plate 00) is moved linearly in the direction of the arrow to irradiate the surface of the mask plate 00 with a laser beam (8). Each time the disk table (3) rotates once, the laser irradiation unit (7) (Maser Grisno Im 250W) moves forward by 0.2%.

For example, if the table rotation speed is 10 revolutions/minute, the irradiation section (7) moves straight from the starting point to the desired set end point at the same speed every two days. In this way, the disk table (3)
The laser beam (8) output from the irradiation unit (7) scans the surface of each mask plate (10) set on the 182x20% of 13-5 size (] 8822275% stationery).
area was scanned and cut out in 10 minutes (8 images x 1
(6 sides) 128 cutout turns can be formed.

By the method of the present invention, greeting cards, stationery, pears,
Decorative paper-cuts for book bindings, margins of invitations, etc., and extra paper used for dyeing can be efficiently produced in large quantities using a rotating disc table, and a suction operation is used. Therefore, the burning smoke generated by the laser beam does not enter the gaps between the coating materials and stain the material surface.
Even if the cutout pattern seems impossible to do manually due to the fineness of the turn, if you prepare a metal mask plate that will serve as the cutout template in advance, it can be done regardless of the difficulty of the turn. , can be manufactured, and its industrial value is extremely high.
