JPS6156868A - Pattern forming method and mold plate for glass surface - Google Patents

Abstract

PURPOSE:To enable a pattern to be successively formed with the pattern concurrently in a stripe, check and gradation, by relatively moving a glass surface and a mold plate and blowing the abrasive sand to the glass surface through a slit- shaped through hole having a side parallelly or diagonally to the moving direction. CONSTITUTION:A mold plate 1, providing a coating layer 7, 7 gluing a vinyl tape or other material on a contact surface with a glass surface 3 and a reverse side in order to prevent extension and contraction while improve work finish accuracy for rubber or other material having softness, forms by punching a suitable number of slit-shaped through holes 2 consisting of a side 4 in parallel to, side 5 diagonally to and a side 6 crossing at a right angle with a moving direction of the mold plate 1 or the glass surfacd 3, allowing sand of emery or the like to pass through the hole 2. Here the mold plate, increasing the blast density in proportion to a length l of the through hole 2 at an equal moving speed and blast density and rapidly changing a degree of gradation due to the diagonal side 5 in proportion to the ratio of the length l to a width (b), enables a stripe, check and gradation pattern to be easily changed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides striped or lattice patterns on sheet glass or other glass surfaces.
The present invention relates to a method for forming a blurred pattern by sandblasting, and a template used directly to implement the method.

When forming a pattern on a glass surface using conventional processing methods, it is necessary to attach tape or the like to the processed surface and remove each pattern one by one, then perform sandblasting, and then remove the tape or the like. In addition, when forming a gradation pattern, a separate single-item processing process must be performed using a circle processing hoe using a blade with the oblique side on the right. Therefore, not only does it take a lot of man-hours and the setup is troublesome, but it also requires a lot of work in all directions.
It was considered extremely difficult to process a checkered pattern like this.

The present invention solves the above-mentioned problems, and its purpose is to be able to simultaneously process striped patterns and checkered patterns in combination with shading patterns, and to process various patterns continuously.

For glass surfaces that can be formed as &! The object of the present invention is to provide a forming method and a template.

That is, the present invention provides a glass characterized in that a template having a through hole for abrasive sand is superimposed on the glass surface, the glass surface and the template are moved relative to each other, and abrasive sand is sprayed onto the glass surface through the through hole. A method for forming a pattern on a surface, and a template that covers the glass surface and has holes for abrasive sand at appropriate places, the holes being at least on a side parallel to the moving direction of the template or the glass surface, or in the same direction. This is a template for a method of forming a pattern on a glass surface, characterized in that it is formed in the shape of a slit with slanted sides.

The present invention will be explained in detail below. Figures 1 to 6 show templates directly used in the practice of the present invention and examples of patterns on the 5ri side formed using the templates. This is a through hole through which diamond sand or other abrasive sand formed by punching out the plate 1 passes, and the through hole 2 is formed by punching out the plate 1 and passes through the abrasive sand.
It is formed in the shape of a slit, consisting of a side 4 parallel to the direction of movement, an inclined side 5, and a perpendicular side 6. Incidentally, although the inclined side 5 is made straight, it may be curved. In any case, the length 1 in the moving direction is can be used.

In other words, under the same moving speed and blast density, ■Through hole 2
The longer the length 1, the denser the blast marks that make up the rough surface, and the larger the ratio (+/b) of the length 1 and width of the through hole 2.
- Stripes, lattice patterns, and blurred patterns can be changed based on the principle that the larger the slope, the more abruptly the degree of gap caused by the slope side 5 changes.

The template 1 is made of flexible rubber or other material, and in order to prevent it from expanding and contracting and to improve the precision of the finished work, a similar material is pasted with nail tape on the contact surface with the glass surface 3 and on the back surface. A coating layer 7.7 is provided, and an appropriate number of through holes 2 of an appropriate shape are formed through the coating layer 7.7.

<Example> A sheet of glass with a thickness of 4.5 mm, a length of 28.2 cm, and a width of 40.7 cm was placed on a conveyor with a width of 200 cm at a constant speed of r8.
While moving, a right triangular through hole with a single hypotenuse of 15 mm in width and 50 mm in length, and a hole in the shape of a right triangle with a width of 5 mm and a length of 50 m.
A rectangular hole with a width of 15cm and a width of 200cm in the moving direction.
A rubber vinyl drawing template of size 18 is set at β1 so that it is in contact with the processed surface of the sheet glass, sandblasted diamond sand (mesh No. 40) from above to form a striped pattern, and then
The r1 daughter plate was processed by changing the direction of movement by 90 degrees to form a lattice pattern. As a result, the blast particle size of the lattice pattern is well uniformed over the entire area, and the side with the blurred pattern and the side without it are clearly distinguishable.

In addition to the above-mentioned examples, various types of sheet glass were processed using similar templates, conveyors, and spraying equipment. The range is plate thickness 2 mm to 2 om, and the diamond sand is mesh 30.
The patterns ranged from around No. 60 to No. 60, but the results were good (q.
The examples in the figure are all blurred patterns (soft, the examples in Figure 4 are all striped patterns waiting for clear lines, and the examples in Figure 6 are of the blurred checkered pattern, and this combination U, l'j) is used to make sheet glass. By tilting it with respect to the moving direction, various changes can be made.

Therefore, according to the present invention, a striped pattern, a checkered pattern, or a combination of these and a shading pattern can be formed very easily, and the abrasive sand can be applied while relatively moving the 6rj child surface and the template. Therefore, a remarkable effect was obtained in which various patterns could be continuously formed.
