Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention provides heavy weight and luxury
Or thick coating on the surface to improve storage durability
Religious trees such as Buddhist altars, Buddhist altar fittings, and sacred fittings that need to form layers
The present invention relates to a method for manufacturing a craft.

[0002]

2. Description of the Related Art Traditionally, traditional craft products such as altar and Buddhist altar are made of natural resin paints such as lacquer and cashew, or various synthetic materials on the surface in order to give weight and luxury and to improve storage durability. The resin paint was applied by a brush or spray device according to the following traditional painting technique. (1) Pretreatment process such as polishing, sealing, and shaving of the surface of the material to be coated.
(2) First undercoating step. (3) Second base coating process. (4) First rough polishing step. (5) Third undercoating step. (6) Second rough polishing step. (7) Intermediate coating process. (8) Finish polishing process. (9) Top coating process.

Of these steps, the undercoating step is mainly carried out using a synthetic resin paint (or a mixture of glue and mud). In addition, repeatedly applying the base coat or performing the intermediate coat in this way is to increase the adhesion between the coating layer and the material to be coated and to form the coating layer thick,
This is to prevent color unevenness due to unevenness and shading on the painted surface. It should be noted that a drying time after coating is required for all of the above coating processes.

Further, in relatively inexpensive woodworking products such as furniture, a surface material such as a synthetic resin film or a synthetic resin panel is attached to the surface thereof with an adhesive in order to save the labor and cost of the painting. Was there.

[0005]

However, the woodwork products painted by the above-mentioned traditional painting technique have the following problems. (1) Most of the above coating processes are heavy labor performed in a poor environment where the paint drips around the worker, the solvent component of the paint is vaporized, and the paint dust is scattered by polishing. It was Then, there is a risk that the worker may inhale the vaporized solvent component and the dust of the paint, which may impair his health. (2) It takes a long time until the coating is completed due to the above-mentioned repeated coating and each time it is dried, which causes a coating worker in a small factory to have excessive working hours. It has become an obstacle to mass production.

(3) In order to form a coating layer thick with a constant quality, even with a base coating or intermediate coating which is only an intermediate step,
This requires a great deal of skill and a great deal of time and effort, which is a considerable burden. As a result, workers cannot concentrate their skills, time and effort on the topcoating process, which requires the most creative ingenuity, and the subsequent decoration processes such as placing gold leaf and attaching parts. It was also a cause. (4) In addition, workers may be allocated to each of the above steps, and for example, a person who applies a base coat may be a mechanical work such as only base coat, in which case the human nature of the worker is lost. .

(5) Along with the aging of coating workers having skilled coating techniques, the shortage of successors has become a problem. (6) In the field of woodworking products that require painting, wood that contains a significant amount of "yani" or "fushi" cannot be used in principle because it may cause poor adhesion of the paint or deformation after painting. Therefore, the wood quality was strictly selected, and the above wood was cut off and discarded, but this was a problem from the viewpoint of effective utilization of wood resources. In addition, the lighter ones with a little "yani" and the ones with a small "fushi" were used with a slight stop or blinding, but the work was troublesome.

(7) Many woodworking products are assembled by fitting a tenon joint or the like, but since the fitting part is not painted in general, the fitting is not done during many years of use. The joint part may be rotted by moisture or may be cracked by volatilization of the resin component. (8) Further, since it takes time to process the fitting portion such as the tenon joint, it has been desired to omit the processing by some method. (9) Since the processing process and the painting process are often performed by different companies, the transportation process between the companies was useless.

Further, in a woodworking product to which a surface material such as the above-mentioned synthetic resin film is adhered, since the surface material is simply adhered by an adhesive or the like, the surface material is peeled off from the adherend material and turned over. There is a problem that bulges or wrinkles are likely to occur. Therefore, it could not be used for Buddhist altars and high-end furniture where storage durability is required.

The object of the present invention is to use traditional painting techniques.
The problems of labor, resources, and durability found in religious woodwork are eliminated by adopting a new covering technique surface material instead of the painting technique, and the weight and weight are comparable to those of the painting technique. It is an object of the present invention to provide a new method for manufacturing a religious woodwork product that can give luxury and storage durability.

[0011]

In order to achieve the above object, the invention according to claim 1 provides a thick coating layer on the surface of a woodwork product.
Of religious woodwork such as altars, Buddhist altar fittings, and sacred fittings
In the method, a space is formed with a wooden core material in the mold cavity
Set as described above, and put a synthetic resin in the space of the cavity.
By injecting, the surface material made of synthetic resin is used as the core material.
Is integrally molded and covered with the
The feature is that the face material is strongly attached to the core material . Here, " religious woodwork" includes not only finished products such as Buddhist altars, Buddhist altar fittings, and sacred fittings , but also parts thereof. There is no particular limitation on the type of “core material” tree. There is no particular limitation on the kind of the synthetic resin of the "surface material", and for example, a thermoplastic resin such as polystyrene resin or ABS resin, a thermosetting resin such as polyester resin, or a resin obtained by mixing these may be used. You can choose. Further, "surface material" not only those coated on the whole of the core member, Ru also include those covered in part.

The surface material can be used as the surface of the product as it is, or an overcoat film can be formed on the surface. In the former case, the following modes are included, for example. A surface material that is integrally molded with the core material using only synthetic resin that has been carefully examined in terms of color, texture, etc. so that it is comparable to conventional traditional painting techniques. In this case, in order to prevent uneven color and unevenness on the surface material, a core material that is hard and does not easily penetrate the synthetic resin is preferable. A two-layer surface material in which an inexpensive synthetic resin that adheres to the core material and the synthetic resin that has been examined as described above on the surface are simultaneously injected into the cavity and integrally molded into the core material.

According to the second aspect of the invention , an overcoat film is formed on the surface of the surface material . Here, examples of the paint for the "top coating film" include natural resin paints such as lacquer and cashew, and various synthetic resin paints. Further, the top coat film includes, for example, the following modes. A coating film obtained by applying the above coating material to the surface of a surface material by a brush or spraying device. A coating film obtained by applying the coating material to the mold surface before the integral molding of the surface material and adhering to the surface material during the integral molding.

According to a third aspect of the invention, the cap
When injecting synthetic resin into the space of the vity, with the surface material
Fitting protrusions (tenon etc.) and fitting made of the synthetic resin
Core parts such as holes (mortises, etc.), fitting grooves, fitting ridges, etc.
Mold integrally.

[0015]

In the invention according to claim 1 , the mold cavity is made of wood.
Set the core material made of metal so that a space is formed, and
By injecting synthetic resin into the tee space, the synthetic resin
A surface material made of fat is integrally molded with the core material to cover it. Therefore, as compared with the conventional traditional coating technique, the work environment is improved without the coating material dripping around, the solvent component being vaporized, or dust being scattered. Further, since the number of steps is drastically reduced, the working time is shortened, and since the integral molding itself is automatically performed in the mold, the labor is reduced and the skill is not required.

Further, the surface material adheres strongly to the core material due to the pressure at the time of integral molding, and particularly when the core material has fine pores through which the synthetic resin can penetrate, the surface material becomes firm. Since it is integrated, peeling of the surface material does not occur for many years and the storage durability is improved. In addition, even for a core material made of wood containing a little bit of dashi, because the surface material absorbs the irregularities and deformations caused by the little bit of dashi and coats the surface smoothly,
There is no need to discard or pretreat these timbers. And this surface material can be coated thickly with a certain quality.

According to the invention described in claim 2, in the above operation
The following effects are added. That is , the surface material coated by integral molding is made of synthetic resin, and even if it is overcoated on the surface, the coating material does not soak into the surface material, and unevenness or unevenness does not occur on the finished surface. Therefore, this surface material fully exhibits the function as the base of the topcoat, and can be substituted for the coating layer up to the intermediate coating in the conventional traditional technique.

According to a third aspect of the invention, the cavity is
When injecting synthetic resin into the space of
A fitting protrusion, a fitting hole, a fitting groove, and a fitting made of the synthetic resin.
The fitting part such as a compound ridge is integrally molded with the core material. That is,
The mating that woodworking processors have worked differently since then
Parts to be formed here by a contractor who molds surface materials
Become. Further, since the fitting portion is made of synthetic resin, painting is unnecessary, and even if it is used for many years as it is, it will not rot or crack due to moisture.

EXAMPLES Examples in which the present invention is embodied in a Buddhist altar stand will be described below with reference to FIGS. This Buddhist altar stand 1 is composed of various parts such as a lower frame 2, an upper frame 3, columns 4, and side plates 5. All of these parts are formed by a core material 9 made of cypress and a surface material 10 made of polystyrene resin coated on the surface of the core material 9 with a thickness of 1 to 5 mm. Has a lacquer top coating film (code omitted).

The lower frame 2 is formed in a rectangular frame shape by a front side 6, left and right side sides 7, and a rear side 8, as shown in FIG. 2 for the upper surface and in FIG. 3 for the lower surface. Of these, the front side 6
In the side edge 7 and the side edge 7, the surface material 10 is coated only on the upper surface and the outer side surface of the core material 9.
Is uncoated. A bottom plate (not shown) is arranged between the front side 6 and the rear side 8.

Mortise 11 is provided at four points on the upper surface of the front side 6.
Is recessed. In addition, a mortise hole 11 and a holding groove 12 extending in the front-rear direction are provided at two positions on the upper surface of each of the left and right sides 5. These mortises 1
1 and the holding groove 12 penetrate the surface material 10 and extend to the middle of the core material 9.

The upper frame 3 is covered with the surface material 10 only on its upper surface, lower surface and outer surface. Further, the upper frame 3 corresponding to the mortise 11 and the holding groove 12 of the lower frame 2
A mortise and a holding groove (not shown) are provided in the lower surface of the concave. Other configurations are almost the same as the lower frame 2.

The support column 4 shown in FIGS. 4 and 5 is the rear support column 4 in FIG. 1, and the front surface, the outer side surface, the back surface, and the upper and lower end surfaces thereof are covered with the surface material 10. Further, a tenon 13 made of polystyrene resin integrally formed with the surface material 10 is provided on the upper and lower end surfaces thereof, and the tenon 13 is fitted in the tenon holes 11 of the lower frame 2 and the upper frame 3. Further, a holding groove 12 extending in the vertical direction is provided on the front surface of the core material 9, and the holding groove 12 extends to the inside of the core material 9 like the mortise hole 11. The columns other than the rear column 4 are substantially the same except for the outer shape and the like, and the description thereof will be omitted.

A surface material 10 is coated only on the outer side surface of the side plate 5, and the lower edge, the upper edge and the left and right side edges of the side plate 5 are holding grooves 12 for the lower frame 2, the upper frame 3 and the columns 4, etc. It is designed to be inserted and held in each.

Next, the Buddhist altar stand 1 constructed as described above
Among the above parts, the method of manufacturing the lower frame 2 will be described as a representative. First, the front side 6, the left and right side sides 7, and the rear side 8 are assembled into a rectangular frame shape by the core material 9, and these are fixed with nails or the like so that they cannot be disassembled.

The square frame-shaped core material 9 is set in a cavity of a molding die (not shown). At this time, the front side 6
The surface material 10 is provided on the upper surface side and the outer surface side of the side edge 7.
To form a space. The thickness of the surface material 10 to be molded is set by this space.

The heat-softened polystyrene resin is injected into the space. The surface material 10 adheres strongly to the core material 9 due to the pressure at the time of integral molding, and particularly when the core material 9 has fine pores through which polystyrene resin can penetrate, the softened polystyrene resin is When it enters the inside of the fine holes and is cooled, it cures in the state of entering the fine holes, so that the surface material 10 becomes a composite body firmly integrated with the core material 9. After the polystyrene resin has hardened, the composite is demolded.

Since the core material 9 and the surface material 10 are highly integrated as described above, the surface material 10 is not peeled off for many years, and the storage durability is improved. Further, the surface material 10 absorbs the unevenness and the deformation caused by the slightly fusible and covers the surface 9 of the core material 9 made of wood containing the slightly fussy, so that the woods can be discarded. There is no need for pretreatment. Therefore, it can contribute to effective use of wood resources and reduction of work processes. Further, this surface material 10 can be thickly coated with a constant quality.

The composite has a mortise 11 and a holding groove 12.
To process. At this time, since the surface material 10 is completely integrated with the core material 9, processing such as drilling, cutting and cutting can be performed in the same manner as in the case of using only the core material 9.

Lacquer as a top coating film is applied to the surface material 10 by brushing, and the lacquer is dried. Here, since the lacquer does not soak into the surface material 10 made of polystyrene resin,
Does not cause uneven color or unevenness on the surface of the applied lacquer. Further, as described above, the surface material 10 can be coated with a constant quality, thick and smooth surface. Therefore, the surface material 10 sufficiently exhibits the function as the base of the top coat, and can be used in place of the coating layer formed by the conventional traditional technique such as the base coat or the intermediate coat. It is possible to bring out the heaviness and luxury that are comparable to those of the above.

As described above, in the composite woodwork product of this embodiment, the core material 9 is set in the cavity of the molding die, and the polystyrene resin is injected into the cavity,
It is manufactured by a method of integrally molding the surface material 10 and the core material 9. Therefore, as compared with the conventional traditional coating technique, the work environment is improved without the coating material dripping around, the solvent component being vaporized, or dust being scattered. Further, since the number of steps is drastically reduced, the working time is shortened, and since the integral molding itself is automatically performed in the mold, the labor is reduced and the skill is not required.

Further, since the work up to the intermediate coating step can be omitted by the surface material 10, the coating worker concentrates his technique and time on the step of forming the top coating film which requires the most creativity. As a result, the painter's motivation for creation can be enhanced and contributes to the recovery of humanity. In addition, a skilled painter can afford to train successors.

As described above, since the core material 9 and the surface material 10 are highly integrated and do not cause the edge of the surface material 10 to be curled, bulged or wrinkled, the finished woodwork is heavy and luxurious in appearance. It will not be lost for many years.

In addition to the above function, the support column 4 has a tenon 1
3 is formed simultaneously with the surface material 10 in the integral molding process. That is, since the trader who molds the surface material 10 also forms the tenon 13, it is possible to omit the cutting work of the tenon 13 which has been troublesome for a woodworking processor in the past, and the transportation process between the traders. Can also be omitted. Also,
Since the tenon 13 is made of polystyrene resin, it does not need to be painted, and even if it is used for many years as it is, it will not rot or crack due to moisture, and its durability will be improved.

The present invention is not limited to the configuration of the above-described embodiment, but may be embodied by being arbitrarily modified within the scope not departing from the spirit of the invention as follows. (1) The core material may be preliminarily processed with fitting portions such as mortises and holding grooves, and then the surface material may be coated. (2) In addition to the tenon 13, the tenon 2 as shown in FIG.
1, the fitting groove (holding groove) 22 as shown in FIG. 7, the fitting ridge 23 as shown in FIG. 8, and other fitting portions can also be integrally formed of synthetic resin. (3) A part of the core material may be hollow to reduce the weight.
