Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention is to engrave a photographic image, a pattern, a figure, a character, etc. on the surface of a nonmetal such as stone, glass, and wood, or a metal such as stainless steel. The present invention relates to a method for engraving an appreciation device product.

<Prior Art> It has been well known that a gravestone is engraved with a character such as a name as a character engraved on a stone or the like. In this product, a rubber sheet mask cover is attached to the entire surface of the tombstone on which the characters are to be engraved, and only the shape of the characters to be engraved on the mask cover is carved by hand. It was obtained by a method of spraying fine iron sand particles and carving only the part without the mask cover, that is, the part in the shape of letters.

However, in this product, the shape to be engraved must be manually formed on the mask cover by engraving the shape, and only a skilled and specific person can do this.

Further, it is difficult for a skilled person to form a delicate design shape or a photographic image.
For this reason, it was simple and could not be aesthetically pleasing.

Therefore, as a means for solving this problem, for example, Japanese Patent Laid-Open No.
JP-A 60-36199 proposes a method of using a mask cover made of an ultraviolet curable liquid resin.

This method is to fill the recess formed by the engraved surface of the substrate and the spacer with an ultraviolet curable liquid resin, cure an appropriate portion of the ultraviolet curable liquid resin by exposure of a floodlight, and then remove the uncured portion. The substrate is washed away to obtain a substrate on which the relief is still mounted, and then the substrate is blasted from the surface on which the relief is mounted.

However, if the ultraviolet curable liquid resin is directly attached to the engraved surface of the substrate as in this method, for example, if the engraving object to be engraved is relatively large and difficult to carry or handle, It is necessary to perform a series of processes until the place where the object to be engraved is present and the ultraviolet curable liquid resin is cured, which causes a problem that the work becomes troublesome.

On the other hand, for example, Japanese Utility Model Laid-Open No. 57-167899 discloses a method of curing an ultraviolet curable liquid resin at an appropriate position and engraving it in advance using a mask cover on which arbitrary characters, pictures and the like are drawn. There is.

The method using this mask cover is such that a UV-curable liquid resin is arranged on a transparent film with characters written in black through the cover film, and a synthetic resin film is placed on the UV-curable liquid resin. Irradiate ultraviolet rays from the side to cure the part of the transparent film other than the black-painted part, bond the synthetic resin film and the ultraviolet curable liquid resin, and then wash the uncured part to bond the synthetic resin film The mask cover is manufactured, and the mask cover is attached to the surface to be engraved by an adhesive means such as a rubber liquid, the synthetic resin film is gently peeled off, and the cut out character portion is engraved with a compressor.

However, in this method, the synthetic resin film is adhered to the engraved surface by an adhesive means such as a rubber liquid on the mask cover, and then the bonded synthetic resin film is peeled off. The cured resin attached to the surface may be peeled off together with the synthetic resin film, and as a result, there is a problem that characters, drawings, etc. may not be engraved in a perfect shape. In particular, for example, when a max cover is manufactured by using letters, pictures, etc. obtained by photoengraving, it becomes a fine net-like pattern in which cured and uncured portions of resin are alternately arranged and partially peeled off. It is easy, and if you try to peel off the synthetic resin film, part of the mask cover will also peel off together. Therefore, it is difficult to apply such a method to a delicate picture or the like obtained by photolithography.

<Problems to be Solved by the Invention> The present invention has been proposed in view of the above circumstances, and it is possible to engrave a letter, a picture or the like obtained by photoengraving on a stone or the like in a perfect form. It is an object of the present invention to provide a method for engraving a device for viewing.

<Means for Solving the Problems> The present invention solves the above problems by providing an engraving method for an appreciation device having the following features.

In the engraving method for appreciating device of the present invention, first, a photographic image, a pattern, a figure, a character, etc. are subjected to photoengraving, and the light transmitting section (10a)
And a non-translucent part (10b)
0).

An ultraviolet curable liquid resin is arranged on one surface side of this amikake film (10), and a thin base film (15) having a double layer of thin and thick is formed on the ultraviolet curable liquid resin. After placing the product so that the one facing the UV-curable liquid resin side, the UV-curable liquid resin can be transferred through the other side of the film by casting UV light from the other side of the film. Light section (10
The part corresponding to (a) is separated into a hardened part (13a) that is hardened and an uncured part (13a) that corresponds to the non-light-transmitting part (10b), and is attached to the base film (15). The mask cover (13) to which the base film (15) is attached is obtained by removing the uncured portion (13a) by a cleaning means or the like.

Next, after attaching the obtained mask cover (13) to the engraved surface, the thick base film (15) is peeled off from the thin one. After that, fine iron sand or the like was sprayed on the surface to be engraved with the mask cover (13) to engrave the portion corresponding to the non-light-transmitting portion (10b) of the above-mentioned amikake film (10). This is a characteristic method.

<Working> In the present invention, the base film (15) is composed of a double layer of a thin film and a thick film, and the base film (15) is formed by using an amikake film (10) formed by photoengraving. After the attached mask cover (13) is produced and the mask cover (13) is attached to the surface to be engraved, only the thick base film (15) is peeled off and fine iron sand or the like is sprayed.

By doing this, as long as it is possible to easily peel off the thin and thick base film (15),
Even if the mask cover (13) is formed into a fine net-like pattern in which cured portions and uncured portions are alternately arranged by using the amikake film (10) obtained by photoengraving, the base film (15 It is possible to prevent the mask cover (13) attached to the surface to be engraved from being peeled off from the surface to be engraved when peeling a thick object.

This makes it possible to engrave a picture or the like with a delicate depiction obtained by photoengraving.

Preferred embodiments of the present invention will be illustratively described in detail below with reference to the drawings. However, the dimensions, shapes, materials, relative positions, etc. of the constituent parts described in this embodiment are not intended to limit the scope of the present invention to them unless otherwise specified. , It is just an example of explanation.

It should be noted that the up, down, left and right in the following description indicate the up, down, left and right in the figure.

The ornament (1) of the embodiment comprises a photographic image (3) drawn on the front of a main body (2) made of stone as shown in FIG.

As shown in FIG. 2, this photographic image (3) has its surface as a base (4) and a recess (5) recessed from the base (4).
And the base (4) are arranged almost alternately, and a photographic image (3)
Is showing.

The concave portion (5) is colored with an appropriate color so that it can be clearly distinguished from the base portion (4). The surface shape of the concave portion (5) corresponds to the shape of the non-light-transmitting portion, which is obtained by subjecting the photographic image (3) to photo-engraving to form an artificial film composed of a light-transmitting portion and a non-light-transmitting portion. Is. That is, this photographic image (3) is drawn by engraving the portion corresponding to the non-light-transmitting portion of the mitsuke film.

To engrave only the non-light-transmitting part of the amikake film, cover the part corresponding to the light-transmitting part with a resin mask cover and spray fine iron sand as the engraving means on the entire surface. Can be done by

By doing so, even a person who is not a skilled person can express even a delicate portion by engraving, and can also depict a photographic image or the like.

As a result, the image has a three-dimensional effect, and it becomes an aesthetic effect as a decoration. In addition, it is possible to engrave a portrait of oneself, which will be pleasing.

Hereinafter, the method of engraving this photographic image will be described in detail.

First step First, the image you want to engrave, such as a photographic image, pattern, design, letters, etc.
By photolithography, an amikake film (10) consisting of a light-transmitting portion (10a) and a non-light-transmitting portion (10b) is formed (Fig. 3). A mask cover (13) for making iron sand as a means for engraving against the engraved surface of the appreciation device product is made by using this amikake film (10).

The manufacturing method of the mask cover (13) will be described. As shown in FIG. 3, a dummy film (10) is placed between the transparent glasses (11) and (11), and a liquid is formed on the upper surface of the dummy film (10) through a thin transparent film (12). Pour the resin and set. Further, a base film (15) for attaching the liquid resin is placed on the upper surface thereof.

This base film (15) is thin and thick.
It is composed of multiple layers (not shown), the thinner one is for attaching the liquid resin, and the thicker one is for facilitating the handling, and is a portion to be removed after being attached to the engraved surface described later.

Then, the ultraviolet rays are projected from the direction of the dummy film (10) (X direction in the drawing). As shown in FIG. 4, by projecting ultraviolet rays, the transparent portion (10
The cured part (13a) corresponding to the part (a) and the non-translucent part (10a)
It can be separated into the uncured portion (13b) corresponding to b).

Acrylic urethane type ultraviolet curing liquid resin is used as a material for the mask cover (13) because it has the property of being cured by being exposed to ultraviolet rays, and the cured resin will be described later. This is because the surface to be engraved can be protected from the blowing of iron sand as engraving means.
The material is not limited to this, and any material having such a property may be used.

Further, (14) and (14) in the figure are spacers for preventing the liquid resin from flowing.

Next, the resin attached to the base film (15) is taken out and washed to remove the liquid resin in the uncured portion.

Second Step After the mask cover (13) obtained in the first step is attached to the entire surface to be engraved, the thicker base film (15) is peeled off.

Then, on the engraved surface with the mask cover (13) attached,
Spray fine iron sand. As a result, only the portion without the mask cover (13), that is, the portion corresponding to the non-light-transmitting portion (10b) of the mitsuke film (10) is engraved on the engraved surface, and the concave portion shown in FIG. 5). Then, with the mask cover (13) attached, an appropriate color is sprayed on the entire surface by spraying or the like to color the mask cover (13), and then the mask cover (13) is removed.

As described above, it is unnecessary to manually form the mask cover (13) as in the conventional case, and a delicate portion can be easily formed in a short time. This makes it possible to depict delicate designs, photographic images, etc. by engraving nonmetals such as stone, glass, wood, etc., or metals such as stainless steel, etc., wall hangings, ornaments, monuments that create aesthetics. We will be able to provide equipment for appreciation such as, shields, tombstones, etc.

<Effects of the Invention> As described in the above embodiments, in the engraving method for appreciating device of the present invention, after attaching the mask cover to the surface to be engraved, only the thick base film is peeled off to remove fine iron. Even if the mask cover is formed by spraying sand or the like into a fine net-like structure in which cured parts and uncured parts are alternately arranged by using the amikake film obtained by photoengraving, the base film When a thick object is peeled off, it is possible to prevent the mask cover attached to the surface to be engraved from coming off the surface to be engraved, and it becomes possible to engrave a delicate picture or the like obtained by photoengraving.
