Abstract

PURPOSE:To manufacture the go(national board of japan)-board and shogi (japanese chess)-board of foursides straight grain that is called the highest quality by trimming a flitch to be obtaining with laminating, fastening by pres sure and adhering olural material unit boards, to which an adhesive is applied, to the four-sides straight grain. CONSTITUTION:Slice working is executed for a Japanese nutmeg material 6 to have a defective part 5 (a knar, a rotten part and damage by worms, etc.), and after that a defective part 5a of a material unit board 2 is hollowed out. Then, a fine quality wood piece 8 is charged to such a hollowed-out part 7 and the fine quality material unit board 2 is manufactured. A coloring adhesive 1 in summer wood color is uniformly applied on the whole surface of the upper surface of the material unit board 2 by a roll coater 13 and a flitch 3 is formed by laminating, press-fastening and adhering these plural material unit boards 2. Then, this flitch 3 is trimmed to the straight grain and worked to a board main body 14. Thus, the go-board and shogi-board can be finally manufactured. When the material unit board 2 is colored in dark Japanese nutmeg tree color in the manufacture stage of the board, the tone of color can be made uniform further.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing Go boards and shogi boards.

[Conventional technology]

Generally, Japanese pine wood is used as the raw material for Go boards and Shogi boards. This is due to the fact that the wood is straight, the grain is not dark, it is highly elastic, it is easy to process, and it also has a good surface finish with a glossy finish.

[Problem to be solved by the invention]

However, due to the depletion of hayao trees in recent years, it has become difficult to obtain haya without defects, and haya go boards and shogi boards have become expensive.

It is an object of the present invention to provide a method for manufacturing Go boards and Shogi boards that can produce Go boards and Shogi boards of the highest quality at a low cost.

[Means to solve the problem]

The method for manufacturing Go boards and shogi boards of the present invention is characterized by laminating and press-bonding a plurality of adhesive-coated veneers to obtain a flitch, and cutting the flitch into square pieces. It is.

[For production]

According to the configuration of this invention, if the small-diameter wood is sliced or used as a raw material veneer by repairing the wood with defective parts, the square Go board 2, which is said to be of the highest quality, can be made.
Shogi boards can be manufactured at low cost.

〔Example〕

1 to 3 show a first embodiment of the invention. The method for manufacturing Go boards and shogi boards is to obtain a flitch 3 by laminating and press-bonding a plurality of veneer plates 2 coated with a colored adhesive 1, and then cutting the flitch 3 into four-sided pillars.

1 and 2 show the manufacturing process of the raw material veneer 2. FIG. Figure 1 shows the process of slicing small-diameter wood 4, which cannot be used to make a Go board or a Shoga board, into 0.2 to 5 mm thickness (al(bl)). Figure [C1] shows the process of adjusting the shape of the raw material veneer 2. Figure 2 shows defective parts 5 (knots, combs, insect bites, etc.)
The bamboo material 6 having a thickness of 0.2 to 5 mm is sliced into a thickness of 0.2 to 5 mm (see the same figure).Then, the defective area 5a of the raw material veneer 2 is hollowed out (see figure (C)), and this hollowed out portion is cut out. 7 is filled with high-quality wood chips 8 (Fig. +d+), which shows the process of manufacturing a high-quality raw material veneer 2. 12 is cuckoo.

Figure 3 shows the manufacturing process of go boards and shogi boards using the material veneer 2 formed as described above, and shows the process of manufacturing Go boards and shogi boards using the material veneer 2 formed as described above. The entire upper surface of the board 2 is coated uniformly with a roll coater 13, and these plurality of raw material veneers 2 are laminated and pressed together as shown in the same figure (bl) to form a flitch 3. Like fcl, the wood is cut into four-sided pillars and processed into the board body 14. Through this, it is possible to finally manufacture Go boards and shogi boards 9 as shown in FIG. If you dye it in the color of Kayagi, you can even out the color evenly.

According to this first embodiment, Kaya's go boards and shogi boards of the highest quality with four-sided pillars without defects can be manufactured at low cost while retaining properties suitable for Kaya's original Go boards and Shogi boards.

Note that Mori may be used instead of Kaya.

FIG. 5 shows a second embodiment. The material veneer 2 is formed by slicing wood IO, which has properties similar to that of hay, into 0.2 to 21 thick pieces. The material veneer 2 is bleached and dyed to give it a hazel color.

The following manufacturing process of the board body 14, the Go board, and the 17-play board 9 is as shown in FIG. Wood with good haze properties 1
As for 0, it is desirable that the specific gravity is 0.42 to 0.54 and the compressive Young's modulus is 300 to 600 kg/cl.

According to this second embodiment, Kaya-style 3-boards and Shogi boards can be manufactured at low cost.

The sixth leap represents the third embodiment. By slicing wood 10 (specific gravity 0.42 to 0.54, compressive Young's modulus 300 to 600 kg/cJ) with properties similar to that of kaya into 0.2 to 2 l thick pieces, and then bleaching and dyeing them. Dye it in a light color. Add 100 g of polyethylene glycol dimethacrylate 50% water solution 11 to this (as shown in BL).
Apply /m.

The manufacturing process of the following board body 14, Go board, and shogi board 9 is as shown in FIG.

With this third embodiment, Kaya-style X boards and Shogi boards can be manufactured at low cost, and polyethylene glycol Mekkurirei can be manufactured at low cost.
1. Because it contains 1., it can produce the unique luster of kaya.

〔Effect of the invention〕

According to this invention, a flitch is obtained by laminating and press-bonding a plurality of veneers coated with adhesive, and this flitch is cut into four-sided pillars, so it is possible to slice small-diameter wood, By repairing defective parts and using it as a single board, it is possible to manufacture Go boards and shogi boards at low cost, and it is also possible to produce Go boards and shogi boards with four-sided pillars that are said to be of the highest quality. be able to.
