Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The method of applying a light wood board side end surface of the present invention is used for manufacturing a light wood board used for furniture, fittings, cases of home electric appliances and the like. In particular, it is preferably used for manufacturing a light-weight wooden board with makeup.

[0002]

2. Description of the Related Art Recently, a method for manufacturing a lightweight wooden board such as a lightweight fiberboard or a lightweight particleboard has been established and has been commercially available from some manufacturers. Since these lightweight wooden boards are lightweight but formed thick, they have a heavy appearance and are expected to be used as boards for furniture, fittings, cases of home electric appliances, etc. . Moreover, a lightweight wooden decorative board in which a decorative sheet or the like is attached to the lightweight wooden board has been desired. Further, it has been desired that the side end surface of the light weight wooden board is processed into an arbitrary shape in consideration of designability, and further, a makeup is applied.

Therefore, as a method of applying makeup to the side end surfaces of such a lightweight wooden board, a decorative sheet is attached to the surface of the lightweight wooden board, and a part of the surface layer of the lightweight wooden board attached to the decorative sheet is left. A part of the surface layer of the above-mentioned lightweight wooden board is attached to the part which becomes the side end surface of the lightweight wooden board by forming the notch by deleting a part of the end of the lightweight wooden board. The method of attaching the decorative sheet (hereinafter, referred to as a fiber-attached decorative sheet) has been used.

However, in these methods, when the thickness of a part of the surface of the lightweight wooden board attached to the decorative sheet is uniform from the end of the decorative sheet toward the central portion of the lightweight wooden board. When the thickness is large, it is difficult to attach the fiber-attached decorative sheet while bending it along the side end surface of the lightweight wooden board. Also, if the thickness is thin, it is difficult to leave a part of the surface layer of the lightweight wooden board attached to the decorative sheet, and the surface of the fiber-attached decorative sheet should be smoothly bent along the side end surface of the lightweight wooden board. Was difficult.

That is, when the thickness of a part of the surface layer of the lightweight wooden board attached to the decorative sheet is thin on the center side of the lightweight wooden board, the angle between the fiber-attached decorative sheet and the end surface of the lightweight wooden board on which the cutout portion is formed is small. When the value is large, the angle at which the fiber-attached decorative sheet is bent becomes large, so that the surface of the decorative sheet cannot be bent in a smooth state. Also, when the angle between the fiber-attached decorative sheet and the end surface of the light-weight wooden board on which the cutout portion is formed is small, it is not possible to sharply remove the tip portion of the light-wooden board, and uncut portions will occur. A step was formed on the surface of the decorative sheet at the portion where the fiber-attached decorative sheet was first bent and attached along the side end surface.

Further, when the thickness of a part of the surface layer of the lightweight wooden board attached to the decorative sheet is gradually reduced from the end portion of the decorative sheet toward the central portion of the lightweight wooden board, at the end portion of the decorative sheet. Since the thickness of the fiber-attached sheet is thick, it is difficult to attach it while bending, and moreover, since the thickness of the fiber-attached sheet is thin on the center side of the lightweight wood board, the same as the above, along the side end surface of the wood light board. A step was generated on the surface of the decorative sheet at the portion where the fiber-attached decorative sheet was first folded and attached.

In the case of a lightweight wooden board, the corners are weak against pressing, so the corners are processed into an arc shape,
It is preferably processed into a chamfered state. That is, in order to make the corners of the wooden board arcuate or chamfered, it is necessary to reduce the angle between the fiber-attached decorative sheet and the end surface of the light wooden board on which the cutout is formed.

[0008]

DISCLOSURE OF THE INVENTION The present invention is a method for applying makeup to a side end surface of a lightweight wooden board, in which a fiber-attached decorative sheet is easily bent along the side end surface of the lightweight wooden board, and the attached fiber is attached. It is an object of the present invention to provide a method for smoothing the surface of an adhesive decorative sheet. Especially, when the corners of the wooden board are processed into an arc shape or chamfered state, a step is formed on the surface of the decorative sheet at the part where the fiber-attached decorative sheet is first bent and attached to the side end surface of the lightweight wooden board. It seeks to provide a way to prevent it from happening.

[0009]

The present invention has taken the following means in order to solve these problems. That is, the thickness of a part of the surface layer of the lightweight wooden board attached to the decorative sheet is gradually increased from the end portion of the decorative sheet toward the central portion of the lightweight wooden board. Further, preferably, the thickness of a part of the surface layer of the lightweight wooden board attached to the decorative sheet is 0.2 to 2.0 mm at the end of the decorative sheet and 1.0 to 2.0 at the central portion side of the lightweight wooden board.
It is set to 4.0 mm. Further, it is preferable to use an ultralight fiberboard as the lightweight wood board.

The lightweight wood board used in the present invention is a plate-like material made of wood material, and examples thereof include lightweight fiberboard and lightweight particle board. Especially, the density is 0.36 g / cm ^3.
The effects of the present invention can be remarkably exhibited when the following ultralight fiberboard is used. The thickness of the lightweight wood board is generally in the range of 12 to 40 mm.

Further, the decorative sheet used in the present invention is not particularly limited, and a decorative sheet conventionally used for producing a decorative plate can be used. For example, a decorative paper that has been printed or resin processed, or a plastic sheet that has been printed,
A printed aluminum foil or the like is used.

Hereinafter, the method for applying makeup to the end surface of the lightweight wooden board according to the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing a state in which a decorative sheet is attached to the surface of a lightweight wooden board.
2 is a part of both ends of the lightweight wooden board of FIG. 1 is deleted,
It is sectional drawing which shows the state in which the fiber attachment decorative sheet and the lacking part were formed. Then, FIG. 3 shows a state in which the fiber-attached decorative sheet is attached to the side end surface of the lightweight wooden board due to the formation of the missing portion in FIG.

First, as shown in FIG. 1, a decorative sheet (2) is attached to one surface of a lightweight wooden board (1).
The sticking method is not particularly limited, but a method widely used in obtaining a decorative plate, that is,
A method of applying an adhesive and thermocompression-bonding can be used.

Next, as shown in FIG. 2, a part of the end portion (4) of the lightweight wooden board is deleted while leaving a part (3) of the surface layer of the lightweight wooden board attached to the decorative sheet (2). Then, the fiber-attached decorative sheet (7) and the lacking portion (5) are formed. At this time, a part (3) of the surface layer of the lightweight wooden board attached to the decorative sheet (2) is made thinner at the end portion of the decorative sheet and gradually thickened at the central portion side of the lightweight wooden board. That is, the thickness of the fiber-attached decorative sheet (7) is thin at the end of the sheet and is gradually increased at the center of the lightweight wooden board.

The thickness of the fiber-attached decorative sheet (7) is preferably 0.2 to 2.0 mm at the end of the sheet and 1.0 to 4.0 mm at the center side of the lightweight wooden board.
If the thickness of the edge portion of the fiber-attached decorative sheet is less than 0.2 mm, the decorative sheet (2) may be damaged when forming the cutout portion, and if it exceeds 2.0 mm, the fiber-attached decorative sheet is bent while being folded. It will be difficult to attach.
Further, if the thickness of the fiber-attached decorative sheet on the center side of the lightweight wooden board is less than 1.0 mm, the first step of folding the fiber-attached decorative sheet and attaching it to the side end surface of the lightweight wooden board causes a step on the surface of the decorative sheet. When it exceeds 4.0 mm, it becomes difficult to bend the fiber-attached decorative sheet.

The method of removing a part of the end portion of the lightweight wooden board is not particularly limited, but a grooving machine, V
It is performed using a machine such as a cutting machine or an NC router. The shape of the cutout portion is arbitrarily determined by the shape, size, etc. of the portion serving as the side end surface of the lightweight wooden board due to the formation of the cutout portion. In addition, when the fiber-attached decorative sheet reaches not only the side end surface of the lightweight wooden board but also the back surface and is attached so as to cover the side edge portion, a missing portion is formed so that the length of the fiber-attached decorative sheet becomes long. Need to be bigger.

Finally, as shown in FIG. 3, a fiber-attached decorative sheet (7) formed by removing a part of the end portion of the lightweight wooden board is used to form a cutout portion of the lightweight wooden board. Attach it to the part (6) that will be the side end surface. As a pasting method, it is general that an adhesive agent is applied to the joint surface and the fiber-adhered decorative sheet is bent and adhered along the side end surface of the lightweight wooden board.

When the thickness of the fiber-adhering sheet is thin on the central portion side of the lightweight wooden board, when the corners of the lightweight wooden board are processed into an arc shape, as shown in FIG. At the first part where the decorative sheet is bent and attached to the side end surface of the lightweight wooden board, the surface of the decorative sheet is not smoothly bent, resulting in a step. The reason for this is that, as shown in FIG. 5, the angle between the fiber-attached decorative sheet and the end surface of the light-weight wooden board on which the cutout portion is formed is small, so that the sharpness of the tip portion of the processing equipment etc. Therefore, a step is formed on the surface of the decorative sheet at the first part where the fiber-attached decorative sheet is folded and attached to the side end surface of the lightweight wooden board.

[0019]

According to the present invention, the light wood board end face is made thicker at the corners of the light wood board because the first part of the fiber-attached decorative sheet to be attached along the side end surface of the light wood board is thicker. Even if the edge is sharp, a part of the surface layer of the lightweight wooden board attached to the decorative sheet acts as a cushioning material, and the surface of the decorative sheet becomes smooth. Also, when the corners of the lightweight wooden board are arcuate or chamfered, the angle between the fiber-attached decorative sheet and the end surface of the lightweight wooden board where the cutout is formed is small, and the sharp edge up to that point is used. Even if it was not deleted by
A part of the surface layer of the lightweight wooden board adhered to the decorative sheet acts as a cushioning material, so that no step is formed on the surface of the decorative sheet.
