Description

[Detailed description of the invention] The present invention relates to a method for producing materials for furniture and fittings.

Traditionally, the surfaces of furniture, fittings, etc. are overlaid with veneer, plastic, paper, cloth, etc. to give them a beautiful appearance, but when forming a curved surface on the periphery or part of the surface, the processing is extremely difficult. It was a difficult tlt. In addition, if you use particle board with good workability, you can freely form curved surfaces.
On the other hand, the outer surface has a rough finish, and the adhesive and undercoat applied to the surface during overlay tend to soak in, resulting in poor adhesion and the time it takes to apply the undercoat.

The purpose of the present invention is to solve these problems and provide a method for producing materials for furniture and fittings that have a beautiful finish on the outer surface and can easily form curved surfaces on the periphery and part of the surface. . Therefore, the feature of the first invention is that a particle port is cut to form a shape having a predetermined curved surface on the outer surface, and a hole slightly larger than the cross-sectional shape of the shape is opened. At the same time, after going through a coating process in which the inside of the mold is passed through a mold filled with photocurable resin, light is irradiated faster than the photocurable resin uniformly adhered to the outer surface penetrates into the mold. The feature of the second invention is that the shape is cured to form a photocured resin layer on the outer surface of the shape. After passing through a pressure roll and a photocurable resin application roll having a curved surface formed to correspond to the curved surface of the shape, a photocured resin is uniformly applied to the outer surface. The resin is irradiated with light and cured faster than it penetrates into the shape, thereby forming a photocured resin layer on the outer surface of the shape.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

1 to 5 show the first invention, in which 1 is a slender plate-shaped member whose center portion bulges in the longitudinal direction and has three stages of curved convex stripes; , particle board 2,
In other words, it is made by cutting wood or other fibrous material into strips using known cutting means from a board material made by solidifying it using an organic binder and factors such as heat, pressure, moisture, and catalysts. .

A photocurable resin layer 3 is coated on the outer surface of the shaped material 1 having a predetermined curved surface, thereby forming a material 4 for furniture and fittings.

Then, various overlay processes (not shown) are performed on this photocuring resin layer 3, so that, for example, as shown in FIG.
is fixed to the periphery of the

Thus, the material 4 is manufactured through the steps shown in FIG. That is, by passing the particle board 2 through a known cutting process 6, a shape 1 having a predetermined curved surface on its outer surface is cut and formed (see FIG. 2). This shaped material 1 is sent to a coating step 9 by passing through a conveying step 8 consisting of a plurality of pairs of rotatable rollers 7 arranged vertically at predetermined intervals.

Specifically, the coating step 9 is configured such that the shaped material 1 passes through a box-shaped mold 10, as shown in FIG.

The mold 10 has a hole 12.12 having a shape slightly larger than the cross-sectional shape of the section 1 on the opposite side surface 11.11, and the section 1 slides into the hole 12.12. The holes 12.12 are opened on the same axis so as to be inserted therethrough. Further, the holes 12 and 12 are each made into a tapered hole enlarged toward the insertion side so that the section 1 can be easily inserted.

The mold 10 is filled with a photocurable resin 13 such as a polyester resin that is cured by irradiation with ultraviolet rays, and the shape kA1 inserted into the hole 12.12 is shaped like an arrow A1.
The photocuring resin 13 is passed through the mold 10 by moving along a cliff as shown in FIG. At this time, the reduced diameter hole 12a of the outlet side hole 12 and the shape 441
The adhesion amount of the photocurable resin 13 is maintained constant in the small gap between the two. Furthermore, leakage of the photocurable resin 13 filled into the mold 10 is prevented through the diameter-reducing hole 12a.

The shaped material 1 that has undergone this coating step 9 is sent to a light irradiation step 14, where it is irradiated with light such as ultraviolet rays set to a predetermined wavelength.
Photocurable resin 13 uniformly adhered to the outer surface of form 1
The material 4 is irradiated with light to harden the material faster than it penetrates into the shape material 1, and a material 4 is formed as shown in FIG. Next, polishing step 15
By going through this process, fine irregularities on the outer surface of the material 4 are polished to form a smooth outer surface. (Note that the polishing step 15 can be omitted if necessary.) Next, to explain the second invention, each step other than the coating step 9 is the same as the first invention, and the known glue J i In the 'ill step 6, the particle board 2 is cut to form a shape 1 having a semi-cylindrical cross section as shown in FIG.

As shown in FIG. 7, the coating step 9 includes a photocurable resin coating roll 16 and a reverse pressure roll 17 formed to correspond to the curved surface formed on the outer surface of the profile 1.
It is composed of a plurality of rollers 1B that transport and support the cough shape 1.

Specifically, the application roll 16 is set to rotate in the direction of arrow B, and the rollers 18 are set to be rotatable.
In cooperation with
send it off to This applicator roll [6 is a drum-shaped roll with a reduced diameter at the center as shown in FIG. 8, and is curved to correspond to the curved surface formed on the outer surface of the shape 1. When the coating roll 16 is rotated in the direction of arrow B while in contact with the outer surface of the material 1, the photocurable resin 13 supplied from a photocurable resin supply device (not shown) is applied to the coating roll 1.
6 to the outer surface of the profile 1. Further, the press roll 17 is also set to have the same shape as the application roll 16, and rotates in the direction of arrow C in the opposite direction to the application roll 16, and rotates in a direction to prevent the section 1 from moving in the direction of arrow A. The photocurable resin 13 is applied uniformly to the outer surface of the shape member 1. (This acts as a so-called squeezing action.) Note that the curved shapes formed on the outer surfaces of the application roll 16 and the press roll 17 can be set to various curved shapes corresponding to the curved shape of the outer surface of the profile 1. In the case of a profile 1 as shown in FIG. 9, a plurality of application rolls 16 are used to coat mutually different surfaces of the cross section at different positions in the longitudinal direction of the profile 1.
・Transfer. Although not shown, the pressure roll 17...
The same shall apply.

The shape 1 having the photocurable resin 13 uniformly adhered to its outer surface in this manner is subjected to a light irradiation step 14 and a polishing step 15 as in the first invention, so that the outer surface of the shape 1 is coated with the photocurable resin. A raw material 4 having a layer 3 formed thereon is obtained.

Note that the present invention is not limited to the illustrated embodiment, and includes, for example, the curved shape of the outer surface of the profile l, the shape of the holes 12, 12 set corresponding to the curved shape, the applicator roll
The curved shape of the outer surface can be freely changed in various ways. Furthermore, in the present invention, the materials for furniture and fittings are defined to include interior decoration materials and building materials.

According to the effects of the embodiments of the present invention, the first invention opens a tapered hole 12° 12 on the side surface 11.11 of the mold lO in the coating step 9, making it easier to insert the tip of the shape material 1, Moreover, the sealing effect for preventing external leakage of the viscous liquid photocurable resin 13 is also great. In addition, in the second invention, the photocurable resin 13 is applied only to the front side (curved side) of the profile 1, and since the resin 13 is prevented from adhering to the back side, the amount of bone attachment is reduced. This makes it possible to reduce costs.

The present invention has effectively achieved its intended purpose with the configuration detailed above. In particular, since the profile 1 is formed by cutting the particle board 2, the entire profile 1 is made of a uniform material, which prevents distortion from occurring and prevents the possibility of peeling of the overlaid veneer, printed paper, etc. At the same time, it is possible to mass-produce the shape material 1 that is inexpensive, easy to process, and has a beautiful curved surface finish. Furthermore, using the shape 1 having such characteristics, the photocurable resin 13 is applied uniformly (-1) to the outer surface of the shape 1, so that the resin 13 is not soaked into the shape 1. Since the resin 13 was quickly irradiated with light and the resin 13 was cured to form a photocured resin group 3 on the outer surface of the shape +A' 1, the material 4 The outer surface of the
When overlaying, it becomes possible to use a material 4 with an excellent finish without adhesion defects, or to apply the finishing paint beautifully and smoothly.
