Abstract

PURPOSE:To perform easily wash processing on the surface of lumber for furniture without depending on manual operation, by a method wherein the surface of the lumber for the furniture is polished by a brush of a turning brush main body. CONSTITUTION:In a brush main body 20, a brush 22 having a wire for its material is provided on the axis 21 of rotation which is in parallel with the surface of lumber 10 for furniture. The surface of the lumber 10 for the furniture is polished by the brush 22 by turning the brush main body 20. At the time of polishing, though the brush main body 20 is pressed against the surface of the lumber 10 for the furniture by fixed pressure, a depth of unevenness of the grain 11 of wood can be adjusted by changing the pressure. In other words, the title method is constituted so that in the case where wash processing is made deep, the summer grain of part 13 is cut more than the winter grain of wood part 12 by making the pressure high and in the case where the wash processing is made shallow, it is good that the summer grain of wood part 13 is cut slightly more than the winter grain of wood part 12. With this construction, uniform wash processing can be performed by a tiny and simple device.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for surface-treating furniture wood, and more particularly to a washing-out method for forming unevenness of wood grain on the surface of furniture wood.

[0002]

2. Description of the Related Art Furniture wood made of natural wood such as cedar and cypress has various surface treatments. Some of them have wood grain as shown in FIG. There is a so-called washout process for forming irregularities. When furniture is made from furniture wood that has undergone such a wash-out process, the surface of the furniture has irregularities in the wood grain, which makes it possible to positively express the wood grain of natural wood, which not only provides a high-class feeling but is also excellent in aesthetics. It can be made to be soft to the touch and have excellent tactile sensation.

In addition, for example, in the case of painting furniture wood having a smooth surface, a paint which can be ground (hereinafter referred to as sanding) by sandpaper or the like is usually applied by applying a paint after coloring the surface and coloring. Paint) is applied and sanded to fill the gaps in the wood grain. In some cases, the sanding paint is applied and the sanding is repeated to completely fill the gaps in the wood grain, and finally a coating paint such as a polish is applied. However, when painting furniture wood that has been washed out,
Since the unevenness of the grain is formed, it is not necessary to fill the gap of the grain, shortening the sanding time mentioned above,
In some cases, application of sanding paint and sanding can be omitted altogether.

[0004] By the way, conventionally, such a washing process of furniture wood is carried out by a so-called broom made by bundling Japanese broom fibers with hemp thread or the like, or is blasted with iron powder or sand. This was done by so-called blast polishing.

[0005]

However, in the conventional washing-out processing method, when the work is manually performed by manufacturing, not only is the work tedious and time-consuming, but it is difficult to uniformly process the surface of the wood. There was a problem that skilled skills were required. Further, when performing by blast polishing, a spraying device and a dedicated booth is required so that the sprayed iron powder etc. do not diffuse to the surroundings, and not only the entire device for washing out becomes complicated and large, The blast polishing has a problem that it takes time and, in addition, iron powder or the like may be locally sprayed to cause unevenness on the washed-out surface.

The present invention has been made to solve the above problems, and an object of the present invention is to wash out furniture wood which can easily and uniformly wash the surface of furniture wood. It is to provide a processing method.

[0007]

[Means for Solving the Problems] The means adopted by the present invention for solving the above problems will be described with reference to the reference numerals used in the drawings. "The unevenness of wood grain 11 is formed on the surface of furniture wood 10. It is a washing-out method of forming, which is characterized in that the surface of the furniture wood 10 is polished by the brush 22 of the rotating brush main body 20.

As the brush body 20, for example, as shown in FIG. 2, a brush 22 may be provided on a rotary shaft 21 parallel to the surface of the furniture wood 10 to be washed out, Further, as shown in FIG. 3, a rotary shaft 21 perpendicular to the surface of the furniture wood 10 to be washed out.
Alternatively, the brush 22 may be provided.

The brush 2 which constitutes the brush body 20
The material of 2 may be any material capable of polishing the surface of the furniture wood 10, such as a wire or a synthetic resin.

[0010]

The method for washing out furniture wood 10 according to the present invention having the above-described structure operates as follows.

First, the brush 2 of the rotating brush body 20.
When the surface of the furniture wood 10 is polished by 2, the brush 2
The surface of the furniture wood 10 is scraped by 2. Here, the surface of the furniture wood 10 has a summer eye portion 13 and a winter eye portion 12
Although there is a wood grain 11 due to the above, since the summer eye portion 13 on the surface of the furniture wood 10 is softer than the winter eye portion 12, this summer eye portion 13 is shaved more than the winter eye portion 12. That is, the unevenness of the wood grain 11 is formed on the surface of the furniture wood 10 with the hard winter part 12 as the convex part and the soft summer part 13 as the concave part.

Further, since the washing-out process is performed by the brush main body 20, a spraying device and a booth unlike the conventional blast polishing is not required, and the entire washing-out device is small and simple. Moreover, furniture wood 1
Since the entire surface of No. 0 is polished by the brush body 20, the surface of the furniture wood 10 is uniformly washed out.

Furthermore, the soft summer-eye portion 13 on the surface of the furniture wood 10 is not only scraped by the brush 22, but also compressed by the brush 22 because the brush 22 itself is an elastic body. Therefore, the surface of the concave portion of the summer-eye portion 13 is hardened to the same hardness as the surface of the convex portion of the winter-eye portion 12. In other words, furniture wood 10
As for the entire surface, the soft summer-eye part 13 has the same hardness as the winter-eye part 12 and is less likely to be scratched.
