Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for manufacturing a decorative panel suitable for use in manufacturing one-off items or small-batch items such as frames depicting family crests or the like.

(Prior Art and its Problems) In general, family crests and the like are valuable to the family, and it is necessary to keep them forever for generations and to maintain their dignity. For this reason, in recent years there has been a tendency to make frames with family crests, etc., display them in the house, leave them to future generations, and preserve them for a long time.

Frames with family crests like this are elegant and require a good finish as well as being painted in an accurate shape. In order to give the part a certain degree of three-dimensionality, manufacturing methods such as casting with a mold or press forming with a metal mold are used.

However, unlike mass-produced items, this type of plaque is, so to speak, a crystal product, and often has a special and complex family crest. Therefore, with the above-mentioned conventional manufacturing method, the manufacturing cost is extremely high, the product has to be expensive, and it is difficult to accurately imitate the family crest.

This ultimately hinders the passing on of the precious traditions of previous generations to future generations, and also leads to problems in which the dignity of the family is lost.

(Means for Solving the Problems) The present invention aims to provide a new method for manufacturing family crest frames, generally decorative panels, which solves the problems of the conventional manufacturing methods described above. This can be achieved by the manufacturing method shown in .

That is, the method for manufacturing a decorative panel according to the present invention is as shown in FIG.
) and irradiate light from the base paper (2) side to form a light-transmitting part (4) along the pattern (1) on the light-shielding photosensitive film (3) to obtain a master film (5). In the master film production process, as shown in FIGS. 3 and 4, the master film (5), the endless frame (6) having a certain height, and the panel material (7) are stacked in this order to form the endless frame (6). ), and a photocurable resin (8) is formed in the space (S) when superimposed.
A basic panel production process in which the resin (8) is cured according to the pattern (1) by filling it with light from the master film (5) side and obtaining a basic panel (9), and the process shown in FIG. The uncured resin (
8) and a finishing step of performing surface treatment on the base panel (9). In addition, according to the best embodiment of the present invention, the design (1) is a family crest (1).
a), ultraviolet rays are used as the light, and stained glass (temporary glass Xl) is used as the panel material (7).
0) is used.

(for production) Next, the operation of the present invention will be explained.

First, in the manufacturing process of the master film (5) shown in Figure 2, light passes through the white part (2a) of the base paper (2), but the pattern (1), which is the black part (colored part), passes through the white part (2a) of the base paper (2). The part is not transparent. For this reason, photosensitive film (
Only the portion facing the margin portion (2a) of 3) is exposed to light. This photosensitive film (3) has a light-shielding property (TL) in its entirety, and when exposed to light, only that part becomes translucent. can be obtained.

On the other hand, in the manufacturing process of the base panel (9), as shown in Figure 4, since light passes only through the transparent part (4) of the master film (5), The photocurable resin (8) only in a portion is cured, and the other portion, that is, the portion facing the margin portion (2a) remains uncured.

Then, in the finishing process, the uncured photocurable resin (8) is washed off, and the base panel (9) is
In particular, a decorative panel (A) can be obtained by polishing and flattening the surface of the design portion and subjecting it to surface treatment such as pasting gold leaf (11).

(Example) Next, a preferred example according to the present invention will be described in detail based on the drawings.

The examples illustrate a method of manufacturing a frame for a family crest, and the manufacturing method will be described below in order.

First, FIG. 1 shows a base paper (2) on which a family crest (1a) to be manufactured is drawn. This base paper (2) is a general white paper (2w) with a family crest (1a) drawn in black.

In addition to the family crest (1a), necessary characters, symbols, and other designs can be drawn on the original paper (2).

Next, the master film manufacturing process will be explained with reference to FIG.

(12) is an ultraviolet light emitting device. The same device ff (12)
It has a box-like configuration with an ultraviolet light emitting lamp (13) arranged inside, and a flat mounting surface (14) made of, for example, a semi-transparent plate, which irradiates upward with approximately uniform ultraviolet light. Be prepared.

First, a base paper (2) is placed on this mounting surface (14), and a photosensitive film (3) is further placed on top of the base paper (2).

As mentioned above, this photosensitive film (3) is a two-layer film that has a light-shielding property on its entire surface, and by irradiating it with ultraviolet rays, only the irradiated area is exposed, thereby exposing half of the two films. It has the characteristic that when it is peeled off, only the light-shielding part that has been exposed to light sticks to one half of the film.

Therefore, as described above, base paper (2) and photosensitive film (3)
After setting, cover the mounting surface (14) with a lid (not shown),
When the light emitting lamp (13) is turned on, only the portion of the photosensitive film (3) facing the margin portion (2a) of the base paper (2) is exposed to light, and as a result, as described above, the photosensitive film (3) of the two sheets is exposed. When the film is peeled off, a light-shielding part facing the margin part (2a) remains on one half of the film, and a light-transmitting part (
4) can be formed.

This one half of the film becomes the master film (5).

In this way, the master film (5) can be produced very easily, and the shape and size of the family crest (LA) can also be accurately transferred to the master film (5).

The temperature of the completed master film (5) is approximately 75℃.
The material is immersed in hot water for about 15 seconds to prevent it from being exposed to ultraviolet rays.

Other photosensitive films that can be used include so-called heat-sensitive films in which the black part of the family crest (1a) generates heat when exposed to light (infrared rays, etc.), and the opposing photosensitive film surface becomes translucent. It is a broad concept that includes things.

Next, the basic panel manufacturing process of forming a family crest on a panel material will be explained with reference to FIG.

First, a master film (5) with its back side facing up is placed on the placement surface (14). This film (5)
A transparent protective sheet (15) is further placed on top of the film (5) to prevent resin from adhering to the surface, and a rectangular endless frame (6) is placed on top of this sheet (15).

This endless frame (6) is formed into a window shape having a constant height. Note that this height determines the thickness of the family crest to be formed. Further, the size of the frame (6) is set to a size that can include at least the family crest of the master film (5) or other designs such as characters to be formed.

Then, in this sected state, open the endless frame (
6) Pour the photocuring resin (8) (for example, "Flex" (trade name) manufactured by Nikkei Kikaku Co., Ltd. - () into the endless frame (
6) Fill the space (S) inside.

Once the resin (8) is filled to the point of overflowing, the stained glass (10) (about 3 mm thick) is placed on top of the endless frame (6), a necessary weight is placed on top, and a predetermined pressing force is applied.

Thereafter, the mounting surface (4) is covered with a lid (17) (FIG. 4) and the ultraviolet lamp (13) is turned on to harden the resin (8) for about 20 minutes.

In this case, the resin that is cured is only the portion of the master film (5) facing the light-transmitting portion (4), as shown in FIG. 4 (vertical cross-sectional view of FIG. 3). That is, since the ultraviolet rays pass only through the transparent portion (4) in the direction of the arrow (H), only the resin (8) corresponding to this direction is cured and adhered to the surface of the stained glass (10).

By using such a photocurable resin (8) that is cured by ultraviolet light, generally light, it is possible to form a resin curing jπζ that sharply stands, unlike thermosetting resins.

Next, in the finishing process, the stained glass (10) is removed, the protective sorting (15) is peeled off from the resin (8), etc., and the uncured resin is washed away, leaving only the family crest (1b) part as shown in Figure 5. Obtain a raised basic panel (9). Note that the uncured resin that is poured off can be reused. Also, the foundation panel (9) with uncured resin removed.
It is desirable to completely cure the resin by exposing it to ultraviolet light again.

Then, by polishing the surface of the family crest (1b) to make it flat and pasting gold leaf (11) on it, for example, it will create a three-dimensional effect that appears on the surface of the stained glass (10).
What's more, you will get a prestigious family crest plaque.

On the other hand, the surface of the stained glass (10) other than designs such as family crests may be left as is, or may be coated with paint of a desired color or poured with resin of a desired color, etc., if necessary. Furthermore, a transparent coating may be applied to prevent the gold foil (11) from discoloring.

Figure 6 shows the family crest frame produced in this way (18
) The completed family crest frame (decorative panel (A)) is shown.

Although the embodiments have been described in detail above, the present invention is not limited to these embodiments.

For example, although a frame for a family crest has been exemplified, it can also be applied to other arbitrary designs and uses such as school emblems and similar items, nameplates, etc., and generally decorative panels.

Although the case in which curing is performed using ultraviolet light is shown, any other light or light component may be used.

Although stained glass (plate glass) is used as an example of the panel material, any glass such as colored glass may be used, and any plate material such as a plastic plate may also be used. Furthermore, the photocurable resin used may be transparent or colored, or may be mixed with jewelry or other decorative materials. In addition, the family crest (1b) was attached directly to the stained glass (1o) during the manufacturing process, but
It is also possible to form only the family crest (1b) portion alone in a similar manner and adhere it to an existing panel material such as a predetermined window glass.

(Effects of the Invention) As described above, the method for manufacturing a decorative panel according to the present invention basically includes a manufacturing process of creating a master film from base paper and a photosensitive film, and using this master film, it is applied to a photocuring resin and flattened. Since this method includes a basic panel manufacturing process in which a three-dimensional family crest is formed on the panel, and a predetermined finishing process in which surface treatment is performed, the following significant effects are obtained.

■ It is extremely easy to manufacture even complex items because it can be manufactured using the original paper with designs such as family crests drawn on it.

In particular, a mold formed by a conventional casting method or a mold formed by a press molding method is completely unnecessary, so that a significant cost reduction can be achieved.

■ Furthermore, since it can be manufactured by directly transferring the base paper, the molding precision for the design is extremely high, and even the smallest parts can be formed accurately.

(2) Furthermore, if the product is produced by directly fixing it to stained glass or the like according to an optimal embodiment, it can be given a tasteful and unique decorative quality, and its commercial value can be increased.

■ Therefore, if it is applied to family crest frames, it will help protect the traditions passed down from previous generations and pass them on to future generations while preserving the 0-gon.
