To form a pattern on the same surface, fill the same pattern with a color material different in color from the above-mentioned base material, and after curing the same color material, reveal an inlaid pattern on the surface of the block by grinding. It is characterized by.

However, since the original version is created by hand,
There is a manufacturing bottleneck in that it requires a skilled person to create the original plate, and it takes a lot of time and effort.

(D) Means for Solving the Problems In the present invention, an original plate is created by an original drawing unit that is controlled by a computer and stores image data of a pattern to be inlaid, and ultraviolet rays transmitted through the original plate are treated with an ultraviolet curable resin. A storage mold is prepared by irradiating the surface with a pattern to be inlaid, and a storage mold made of a plastic material that is soluble in water, solvent or heat is prepared using the storage mold. A mold is made using, and a base material that is cured in the mold after casting is injected into the mold to cure it, and the consumable mold is removed from the surface of the block generated by curing the base material to remove the same surface. A pattern is formed on the block, a color material having a color different from that of the base material is filled in the pattern, and after the color material is cured, an inlaid pattern is exposed on the surface of the block by grinding. To provide a manufacturing method for inlaid product It is intended.

(E) Operation / Effect According to the present invention, the XY controlled by the computer storing the image data of only the surface layer is used for producing the original plate.
A pattern to be inlaid is formed by an original drawing means such as a plotter.

And to input the image data to the computer,
You can input using the keyboard or mouse while looking at the display, or you can scan and input original hand-drawn images or photographic original images with a scanner.Once you have input the image data to the computer, the XY plotter will do the rest. Automatically cuts out the pattern that should be inlaid.

In particular, in the present invention, it is possible to easily change the positive / negative of the original plate, change the position and part of the pattern, enlarge / reduce, and in the case of a character, change the font such as flat or italic. It is possible to drastically reduce the labor and time for producing the original without requiring a person.

(F) Example Prior to describing the example of the present invention, the original plate (2) used for manufacturing the inlaid product of the present invention will be described.

The original plate (2) has a transparent base layer (T) as shown in FIG.
In the raw film (F) for an original plate, in which the light-shielding surface layer (R) is releasably laminated, a pattern to be inlaid is formed by the method shown in the flow chart of FIG.

First, a design concept of a pattern (8) such as a painting or a character to be inlaid is determined (50).

Then, while displaying the pattern image on the display (51), computer drawing is performed using a keyboard or a mouse (52), or the original image is hand-drawn (53) and scanned by a scanner (54), and the image data is computerized. To enter.

Since the image data input in this way can be easily changed, such as positive / negative, the position and part of the pattern, enlargement / reduction, and in the case of characters, characters such as flat and italic can be easily changed. An expert is not required to create the original image, and the labor and time for creating the original plate can be greatly reduced.

Next, the original drawing means (P) such as an XY plotter is driven by the above image data, and only the light-shielding surface layer (R) of the original (2) is driven by the cutter (C) of the original drawing means (P). A notch is made based on the image data, and the notched portion is peeled from the surface layer (T) to create an original plate (2) in which a pattern (8) to be inlaid appears (55).

Also, as another method of making the original edition, hand drawn original paintings (53)
The original film (F) can be used as the original plate (2) by taking a photograph of it (56).

Next, regarding the production of the product with the inlaid pattern using the above original plate (2), the flowchart of FIG. 2 and FIGS.
This will be described with reference to the schematic view of the manufacturing situation shown in the figure.

3 to 6 show the manufacturing process of the storage mold (M), in which the original plate (2) and the cover film (3) are placed on the upper surface of the glass plate (1) in this order, and the upper surface of the film (3). A liquid ultraviolet curable resin (4) is applied to and the base film (5) is attached to the same application surface (Fig. 3).

Here, the UV curable resin (4) will be described. The resin (4) is a urethane or polyester photopolymer, and the cover film (3) has a thickness of 30 μm.
The polypropylene film and the base film (5) are polyester films having a thickness of 100 μm.

Next, the glass plate (6) is placed on the upper surface of the base film (5), and the same resin (4) is used in the group of ultraviolet lamps (7) arranged so as to sandwich the upper and lower glass plates (6) (1). The pattern (8) of the original plate (2) is printed on.

Therefore, the transparent portion from which the light-shielding surface layer (R) has been peeled off and the ultraviolet curable resin (4) between the transparent portion and the base film (5) are cured (FIG. 4).

Next, the uncured resin (4) is washed away with a washout solution (9) such as a solution containing a surfactant or the like, and a projected pattern (8) is exposed on the lower surface of the resin (4) ( (Fig. 5).

Then, the remaining ultraviolet curable resin (4) is irradiated with ultraviolet rays again and after-cured to be a storage type (M) (57) (FIG. 6).

Next, regarding the production of the inlaid pattern product using the original plate (2), the flowchart of FIG. 2 and FIGS.
This will be described with reference to the schematic view of the manufacturing situation shown in the figure.

Water, a solvent or a heat-soluble plastic material, for example, paraffin having a melting point of about 55 ° C., is cast into the storage mold (M) produced as described above to give a pattern of the storage mold (M). A consumption type (W) is produced by transferring (8) (58) (seventh)
Figure).

Next, a mold (10) for casting the base material (11) is prepared. The direct storage mold (M) is placed on the inner bottom surface of the mold (10) with the mold surface facing upward. Or (59) or the consumption mold (W) is placed on the inner bottom surface of the mold (10) with the mold surface facing upward (60), and the base material (11) is kneaded (61) mold. It is poured into the frame (10) (62), backup concrete is cast (63), cured and cured (64), and the block (12) is produced (Fig. 8).

The base material (11) selects the grain size of the material according to the fineness of the pattern (8). The finer the pattern (8), the finer the grain size is used. In addition, as the base material material of fine particle size, cement, mortar,
There are those that solidify by hydration reaction such as gypsum, and those that mix silica fume, fly ash, limestone, etc., which have been finely ground to a particle size of 1 μm or less, and also those that contain a swelling agent.

Further, there is also one in which a powdery fine aggregate is mixed with a thermosetting resin such as an unsaturated polyester resin.

In addition, in order to prevent bubbles from being mixed into the base material (11) to be injected into the mold (10) and damaging the pattern (8), the kneaded base material (11) is vacuum defoamed before casting. To process.

It is also possible to attach the mold (10) to a centrifugal molding machine and cast the base material (11) in a compacted state by using centrifugal force.

Then, the block (12) in the form (10) is taken out at the same time as the consumption type (W), and the consumption type (W) is mechanically stripped (65), washed with hot water or a solvent, or by heat. It is dissolved and removed (66) (Fig. 9), and the concave portion after the mold (W) is removed is filled with a color material (13) different in color from the base material (11) (67) (Fig. Figure 10), the same base material (11)
Waiting for the hardening of (68), the surface of the block (12) is polished with a grindstone (14) or the like to grind out the pattern (8), thereby manufacturing a product (B) with an inlaid pattern (69). (No. 11
Figure).

When the above-mentioned paraffin is used as the consumption type (W) material, the same type (W) can be dissolved and removed using hot water, and the paraffin thus removed can be reused after being separated from water. .

In addition, since the same type (W) is melted to remove the consumption type (W) from the block (12), the fine pattern is not damaged and the fine pattern of the original plate (2) is faithfully reproduced. It

The material of the color material (13) is the base material (11) described above.
It is possible to freely select the color by using the same material grain size as the above and mixing the same material with a pigment or the like.

Furthermore, when the consumable type (W) is produced, each part of the same type (W) is made of materials having different solubilities, for example, paraffins having different melting points or materials having different solvents. It is also possible to reveal a multicolor inlaid pattern by sequentially removing each part of W) at different temperatures or with different solvents and filling the color material (13) each time.
