Description

  The present invention relates to a method for manufacturing a flooring material, and more particularly, to a method for manufacturing a flooring material capable of suppressing color unevenness.

  Wooden flooring is widely used as residential flooring. In the wood flooring which laminated the decorative board on base materials, such as a plywood, what has various hues and hues, such as white flooring, is prepared. The user can coordinate the wooden flooring according to the color of the joinery and the wall surface from among the abundant variations. Patent Document 1 discloses a flooring to which finish coating is applied. In the flooring disclosed in Patent Document 1, a decorative groove, a half groove (chamfered portion), a fitting convex portion (male solid portion), and a fitting concave portion (female real portion) are processed in advance. And after the said process, the whole surface of a flooring material is painted by roll coating, spray coating, etc.

JP 2005-193539 A

  However, the floor material disclosed in Patent Document 1 may have uneven color tone between the decorative groove and the half groove. More specifically, the decorative groove is a closed groove, and the paint stays in the groove. For this reason, the color tone of the makeup groove becomes darker. On the other hand, the semi-groove is a semi-open groove (chamfered portion), and the paint does not stay and flows immediately. For this reason, there is a concern that the color tone of the half groove becomes thin. It is possible to repaint only the thinned half groove, but it is difficult to match the color tone of the decorative groove.

  Then, this invention aims at provision of the manufacturing method of the flooring which can suppress the nonuniformity of a color tone.

The invention according to claim 1 for solving the above-mentioned problem is that the surface of the plate body on which the decorative groove and the V-shaped groove are formed is coated, and then cut along the V-shaped groove. The floor material manufacturing method of forming a chamfered portion by the remainder of the same V-shaped groove appearing at the end of the plate body, wherein the V-shaped groove is formed on the surface in the vicinity of both end portions of the plate body, The decorative groove is formed on the surface of the plate body inside the V-shaped groove on both sides, and both end portions of the plate body are cut and removed along a valley line that is the deepest portion of the V-shaped groove. Accordingly, the chamfered portion formed at the edge of the cut end surface with the remaining half of the V-shaped groove and the decorative groove having the same color tone by the coating and the chamfered portion remain on the surface of the plate body. It is a manufacturing method of the flooring characterized by making it do.

  The decorative groove and the V-shaped groove are coated under substantially the same conditions, so that the color tone of both is equal.

  After the above coating, it is cut along the V-shaped groove, and a chamfered portion is formed by the cut surface. That is, since the decorative groove and the chamfered portion are painted under substantially the same conditions, it is difficult for a difference in color tone between them.

  According to the floor material manufacturing method of the present invention, unevenness in color tone can be suppressed.

It is sectional drawing which shows the flooring manufactured with the manufacturing method of the flooring which concerns on embodiment of this invention. It is sectional drawing which shows the manufacturing method of the flooring which concerns on embodiment of this invention, (a) is a grinding | polishing process, (b) is a groove | channel formation process, (c) is a coating process, (d) is a cutting process.

  Below, embodiment of the manufacturing method of the flooring of this invention is described in detail, referring drawings. In addition, the following description is for facilitating the understanding of the embodiment, and the present invention should not be understood to be limited thereby.

  As shown in FIG. 1, the flooring 1 is a wooden flooring called flooring. The flooring 1 is used by being connected in the horizontal direction.

  The flooring 1 is manufactured by the manufacturing method of the flooring 1 according to an embodiment of the present invention described later. The flooring 1 is composed of a plate body 2. The plate body 2 is formed of plywood, and a plurality of single plates (not shown) are stacked. In the cross-sectional view of FIG. 1, hatching is omitted for easy understanding of the structure of the flooring 1.

  A decorative groove 4 and chamfered portions 5 and 6 are provided on the surface 3 of the flooring 1. The decorative groove 4 is a V-shaped groove and is a concave portion that forms the groove pattern of the flooring 1. The chamfered portions 5 and 6 are portions where the edges 7 and 8 (peripheries) of the end surfaces 11 and 12 are chamfered, respectively. When the plurality of flooring materials 1 are connected, the appearance similar to the decorative groove 4 appears by combining the chamfered portions 5 and 6 with each other.

  A male real part 13 and a female real part 14 are provided on the end surfaces 11 and 12 of the flooring 1, respectively. The male real part 13 is a convex part, and the female real part 14 is a recessed part. When the floor materials 1 are connected, the male part 13 and the female part 14 are fitted.

  2 (a) to 2 (d) are cross-sectional views showing a method for manufacturing the flooring 1 according to the embodiment of the present invention, in which FIG. 2 (a) is a polishing step, FIG. 2 (b) is a groove forming step, FIG. 2C shows a painting process, and FIG. 2D shows a cutting process. In FIG. 2, hatching is also omitted to facilitate understanding of the laminated structure of the flooring 1.

  2A, the surface 3 of the plate 2 is polished (sanded) by a polishing machine 20 called a sander or a belt sander. This is because the plate body 2 manufactured by a pressing process or the like is in a state in which a plurality of single plates are stacked, and the surface 3 has roughness.

  In the groove forming step of FIG. 2B, the decorative groove 4 and the V-shaped grooves 9 and 10 are formed on the surface 3 of the plate body 2. The V-shaped grooves 9 and 10 are concave portions having substantially the same shape as the decorative groove 4. The V-shaped grooves 9 and 10 are disposed on both sides of the decorative groove 4 in the horizontal direction of FIG. In this case, it is desirable that the V-shaped grooves 9 and 10 are arranged as close to both side end portions as possible.

  In the painting process of FIG. 2C, the surface 3 of the plate body 2 is painted with the sponge roller 21. At this time, the decorative groove 4 and the V-shaped grooves 9 and 10 are also painted.

  In the cutting step of FIG. 2 (d), the plate body 2 is cut along the V-shaped grooves 9 and 10. That is, it is cut at the position of the virtual line (two-dot chain line) illustrated in FIG. The cutting site in the V-shaped grooves 9 and 10 is the deepest part and is a valley line.

  End surfaces 11 and 12 are formed on both sides of the cut plate 2, respectively. Chamfered portions 5 and 6 are formed on the edges 7 and 8 (periphery) of the end surfaces 11 and 12, respectively. A male real part 13 and a female real part 14 are formed on the end faces 11 and 12, respectively. The decorative groove 4 is located inside the edges 7 and 8 (periphery).

  As described above, the flooring 1 is completed through the steps of FIGS. 2 (a) to 2 (d).

  In the manufacturing method of the flooring 1 according to the embodiment of the present invention, the decorative groove 4 and the V-shaped grooves 9 and 10 are coated under substantially the same conditions, so that the color tone of both is equivalent. Then, after the painting step, the plate body 2 is cut along the V-shaped grooves 9 and 10, and the chamfered portions 5 and 6 are formed by the cutting. That is, since the decorative groove 4 and the chamfered portions 5 and 6 are coated under substantially the same conditions, a difference in color tone between the two is unlikely to occur.

  As described above, in the method for manufacturing the flooring 1 according to the embodiment of the present invention, the uneven color tone of the surface 3 of the flooring 1 can be suppressed.

  In the present embodiment, the V-shaped grooves 9 and 10 have the same shape as the decorative groove 4, but the present invention is not limited to this. For example, the shape of the V-shaped grooves 9 and 10 and the shape of the decorative groove 4 may be different.
