[0002]

2. Description of the Related Art A cut surface of a plate cut out from a hardwood has a design of a duct structure, which is rich in design. For this reason, it is used as various kinds of wooden members, but there is a situation that the supply amount of non-processed materials for hardwood is relatively small and expensive.

[0003] For this reason, as shown in FIG. 3, a pattern of a duct structure of hardwood and a concavo-convex pattern 71 corresponding to the pattern are formed on a resin film 70 of vinyl chloride or the like.
What is provided is a variety of relatively inexpensive but inferior design materials, such as laminated wood, plywood, or fiber, which are attached to the surface of a plate material 10. In addition, resin film 70 such as vinyl chloride
Instead, a slice 80 obtained by slicing a hardwood to a thickness of about 0.5 mm, that is, a slice 80 provided with a conduit tissue pattern 81 is also provided. In addition, instead of the vinyl chloride film 70 or the sliced leaf 80 of hardwood, there is also provided a product in which the above-mentioned pattern is printed or a paper film in which irregularities are formed together with the printed pattern is attached. In addition, there are also provided those in which a pattern is printed on the surface of the above-described various plate members 10.

[0004]

In the case of the wooden member shown in FIG. 3, it is necessary to attach a resin film 70 of vinyl chloride or the like or a thin leaf slice 80 of hardwood to the surface of the wooden plate material 10, and the cost is accordingly reduced. There is a problem that comes up.
Further, when a resin film 70 of vinyl chloride or the like is stuck, there is a problem that the feel, texture and the like are slightly different from those of a wooden material, and it is not possible to sufficiently cope with the real orientation. In addition, since the hardwood slices 80 are easily rounded or torn, there is a problem that a great deal of care is required for handling during storage and pasting. Furthermore, in any case, since there is a difference in the expansion / shrinkage ratio between the film or sliced piece and the wooden plate material 10, it is easy to cause poor adhesion, warp or bend, easily peel off, or There is a problem that it is easily deteriorated. In addition, when the pattern is printed on the surface of the above-described various plate materials 10, there is no fine unevenness such as a conduit pattern on the cut surface of the hardwood, so that it has a feeling of nodding, and there is a problem that it cannot sufficiently cope with the real orientation.

[0005] It is an object of the present invention to enable a wooden member having a good design to be manufactured at a lower cost than before. It is another object of the present invention to provide a wooden member whose feel, texture and the like do not differ from a plate cut out from hardwood. It is another object of the present invention to avoid cumbersome labor in storage and operation of materials. It is another object of the present invention to prevent problems such as poor adhesion, warpage, bending, and peeling.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. In the following examples, the present invention is applied to a board (laminate) 10 formed by bonding coniferous wood pieces. However, the hardwood glue, the above-described fiber material, plywood, or softwood or hardwood lacking in design can be used. The present invention can be similarly applied to various wooden plate materials and square materials such as solid wood.

FIG. 1A shows a wooden board which is an example of an embodiment of the present invention. This wood board is made of 10 pieces of coniferous wood
(b) on the surface of the laminated wood 10 formed by bonding a to 10d.
A concave pattern 11 simulating a conduit pattern 21 appearing on one cut surface of a hardwood plate material 20 shown in FIG. In the figure, 19 is a grain of a conifer, and 21a, 21b
Is the conduit pattern that appeared on the other cut surface of the hardwood board 20.

The concave pattern 11 of the laminated wood 10 is formed as follows. First, a photograph is taken of a conduit tissue pattern 21 (a pattern in which a concave portion of the conduit tissue that appears on a cut surface in a direction substantially along the conduit appears in a darker color than the surroundings) 21 shown in FIG. 1B, and based on this photograph, Create a mask film for etching.

Next, the peripheral surface of the metal roller is covered with the above mask film, and the surface of the metal roller is removed so that the corresponding portion remains as a convex portion except for the corresponding portion of the conduit texture pattern 21 except for the corresponding portion. After etching to form the convex pattern 31 corresponding to the conduit texture pattern 21, the mask film remaining on the convex pattern 31 is removed. As a result, FIG.
The roller 3 shown in FIG. The convex pattern 31 corresponds to a concave portion of the duct tissue that appears on the cut surface of the hardwood, and thus has a height of, for example, about 0.5 mm at the maximum.
In the drawings, the concave patterns 11, 21 and the convex pattern 31 are drawn as a planar pattern, but actually, the concave pattern or the convex pattern having a depth or height of about 0.5 mm at the maximum is actually used. is there. However, since the degree of the unevenness is minute, it is drawn as a planar pattern in the figure.

The metal roller 3 thus obtained is rotatably supported as shown in FIG. 2 (b) or (c), and after the laminated material 10 is pressed against the lower peripheral surface of the metal roller 3, both are pressed. Drive synchronously. As a result, the laminated material 10 advances in the direction of arrow a, and the metal roller 3 rotates at the same peripheral speed in the direction of arrow b, so that the surface of the laminated material 10 has a concave portion as shown in FIG. The pattern 11 is formed.

FIG. 2B shows a concave pattern 31 by supplying colored ink via a hopper 52 to a sponge 51 arranged so as to be in contact with the upper peripheral surface of the metal roller 3.
Is formed by applying a coloring ink into the concave portion pattern 11 for coloring. Here, the color of the coloring ink is the same as the color of the duct tissue pattern 21 of the hardwood. Note that rubber can be used instead of the sponge 51.

FIG. 2C shows a colorant transfer sheet (carbon sheet or the like) 60 stretched between a delivery roller 62 provided on the upstream side of the metal roller 3 and a take-up roller 61 provided on the downstream side.
Is inserted into the press-contact portion between the metal roller 3 and the laminated material 10, and in this state, the above-described forming operation of the concave pattern 11 is performed, so that the colorant impregnated or carried on the transfer sheet 60 is in the concave pattern 11. Is transferred and colored.
The color of the colorant is similar to the color of the duct tissue pattern 21 of the hardwood.

As shown in FIG. 2 (b) or (c),
When the concave pattern 11 is formed, the concave pattern 11 can be colored.

The coloring of the concave pattern 11
Can be performed after the formation. For example, if the concave pattern 11 is formed without using the sponge 51 or the like in FIG. 2B or the transfer sheet 60 in FIG. Since a larger amount of the coloring liquid adheres to the portion than the surroundings and the portion is deeply colored, it is possible to obtain a natural pattern of the duct tissue pattern.

Next, an original pattern is painted on the surface of a wooden material (a wooden material shaped according to the intended use, such as the above-mentioned laminated wood 10 formed by bonding wooden pieces 10a to 10d). The case where the above-described recess pattern 11 is formed after being hidden by will be described with reference to FIG.

First, a transparent undercoat is applied to the surface of the laminated wood 10 on which a pattern is to be formed. For example, UV-12 (Eulette V Rose) manufactured by Gengen Chemical Industry Co., Ltd. is sprayed and applied. After drying, fluff is removed using # 320 sandpaper. Next, coloring is performed. For example, U4-3501 (Eurette enamel / oak color) manufactured by Gengen Chemical Industry Co., Ltd. is spray-painted.

After drying of the colorant, the colorant is partially and randomly chamfered to various widths and to various depths. This depth varies depending on the coating thickness of the colorant, for example, 1 μm
Various depths in the range of ４００400 μm, preferably various depths in the range of 1 μm to 100 μm. This depth is usually shallower than the depth of the recess pattern 11 described above. The step of removing the coloring agent is performed, for example, by referring to FIG.
As shown in (b), a large number of metal wires (thin metal wires or thin metal strips used for metal scourers, etc.) 91 are randomly projected from the peripheral surface (and / or so as to go around). The present invention can be implemented by rotatably supporting the provided roller brush 9 and rotating the roller brush 9 while advancing the wooden material while the colored surface is pressed against the roller brush 9. The fine irregularities randomly formed as described above become irregular reflection surfaces that scatter light incident on the colored surface. That is, it acts so as to eliminate the feeling of nodding on the colored surface. In addition,
In this step, any fine and random irregularities as described above can be formed. That is, it is sufficient that the irregular reflection surface can be formed, and the roller brush 9 described above need not necessarily be used. In other words, it is only necessary to be able to scrape as described above using a tool having the same effect as the roller brush 9.

Next, as described above (paragraph number "001"
5) to “0019”) to form the concave pattern 11. As shown in FIG. 4A, the step of forming the concave pattern 11 and the above-described step of shaving off the colorant can be exchanged.
Further, when the coating thickness of the colorant is sufficiently small, the above-described step of removing the colorant may be performed before the step of coating the colorant. In this case, instead of scraping off the colorant, the surface to which the colorant is applied is scraped off in advance at random. Even in such a case, the irregular reflection surface can be formed.

After the formation of the concave pattern 11 and the above-mentioned fine unevenness, a sealing color is applied. For example, Z7-3655 (Metmail) manufactured by Gengen Chemical Industry Co., Ltd. is brush-coated.
Furthermore, after drying, it is polished lightly using # 800 sandpaper. Thereafter, overcoating is applied. For example, spray painting is performed using UF-47-30 (Needs F2 matte 30%) and Z3-3689 (Punchaku PG Dark Oak) manufactured by Gengen Chemical Industry Co., Ltd. After drying, an overcoat is further applied, if desired or necessary. For example, UF-47-30 (Needs F2 gloss 30%) manufactured by Gengen Chemical Industry Co., Ltd. is spray-painted.

In this way, it is possible to obtain a wooden member in which the pattern originally present on the surface of the wooden material is hidden by the coating and the feeling of nopelli caused by the coating is eliminated.

In the above description, the case where the wooden member is plate-shaped is described, but the shape of the wooden member of the present invention is not limited to a plate. Examples of uses of the wooden member of the present invention include wooden exterior materials such as outer walls, fences and wisteria shelves; There are various uses such as wooden fittings such as a closet, a wooden closet, a wooden table, a wooden chair, a wooden closet, a wooden bed, wooden furniture such as a furniture-like kotatsu, and a wooden playground equipment such as a wooden slide.
