Description

[Detailed Description of the Invention] The present invention is a folding device for a decorative panel, and more specifically, the present invention is a folding device for a decorative panel. This invention relates to the bending device used.

Generally, in order to mold this type of decorative panel, a pair of substrates 1 and 2 placed apart from each other are adhered to the back side of a decorative board 3 made of melamine resin or the like to form a panel blank 4, Both boards 1 and 2
By bending the decorative board 2 inward at the corresponding position between them, the panel blank 4 is formed into an arc-shaped corner part 5.
It is formed into a shape in which the vertical surface 6 and the horizontal surface 7 are continuous with each other. As shown in FIG. 1, the bending device used when bending the decorative board 3 is a
It is provided with a bending base 8 which supports each of the substrates from the back side and raises one of the substrates 2, and a pressing head 9 which presses the decorative board 3 from the front side at a position corresponding to the corner portion 5. By the way, the pressing part 10 at the tip of the pressing head 9 has conventionally been used to press the decorative board 3 so that the corner part 5 of the decorative board 3 can be finished smoothly.
The shape is such that a slight relief 22 is formed at the end of the corner portion 5 when it comes into contact with the corner portion 5. For this reason, the decorative board 3 cannot be pressed against the edges of the boards 1 and 2 facing the corner portion 5, and when the decorative board 3 is bent, the decorative board 3 may be lifted off the boards 1 and 2 at this part. . Furthermore, when the vertical surface 6 or the horizontal surface 7 stands up with a sufficiently large length compared to the pressing head 9 as shown by the imaginary line in the figure, it is possible to provide a contact 21 that presses that surface from the front side. When the rise is small compared to the head 9, the abutment 21 cannot be provided, so there is a drawback that the angle formed by the vertical surface 6 and the horizontal surface 7 varies depending on the product.

The present invention has been developed in view of the above points, and its main purpose is to prevent the decorative board from lifting off from the substrate when forming the corner part. Another objective is to ensure that the angle formed by the vertical and horizontal surfaces does not vary from product to product.

Embodiments of the present invention will be described below based on the drawings. The folding device for a decorative panel according to the present invention includes a panel base plate 4 formed by bonding a pair of substrates 1 and 2 spaced apart from each other to the back surface of a decorative board 3.
This device forms a shape in which a vertical surface 6 and a horizontal surface 7 are continuous through an arc-shaped corner portion 5 by bending the decorative board 3 inward at a position corresponding to between both substrates 1 and 2. A bending base 8 supports both substrates 1 and 2 from the back side and raises one substrate 2 to form a corner portion 5 on the decorative board 3, and a bending base 8 that supports both substrates 1 and 2 from the back side and raises the decorative board 3 to form a corner portion 5 on the decorative board 3. A pressing head 9 that presses from the side is provided, and an arc-shaped pressing portion 10 is formed at the tip of the pressing head 9.
A pad 11 made of an elastic material is provided at one end of the pad 11.
is fixed, and the pad 11 presses the decorative board 3 from the surface and presses it against the edge facing the corner portion 5 of one board 2, and the other end of the pressing part 10 presses the decorative board 3 from the surface and presses it against the edge of the other board 2. 1 corner part 5
It is pressed against the edge facing the surface. As shown in FIG. 2, the panel blank 4 is made by bonding wooden substrates 1 and 2 to the back side of a decorative board 3 made of melamine resin, etc., and the substrates 1 and 2 are divided into two parts. There is. When forming the panel blank 4, the third
As shown in the figure, the decorative board 3 is adhered to the surface of the flat veneer 16 with grooves 15 formed on the surface, and there is a gap between the flat veneer 16 and the decorative board 3 in the part corresponding to the grooves 15. Then, it is sufficient to cut only the flat veneer 16 along a cutting line shown by an imaginary line in the figure with a width approximately equal to the width of the groove 15. In this way, the pair of substrates 1 and 2 are adhered to the back surface of the decorative board 3 in a spaced-apart manner. The decorative board 3 has flexibility and can be bent at a position centrally located between the substrates 1 and 2.

A bending device is used to bend the panel blank 4. The bending base 8 of the bending device has both the above-mentioned substrates 1,
The substrate 2 is constructed of a vertical base 17 and a horizontal base 18, each of which supports the substrate 2 from the back side, and the vertical base 17 is designed to rise to raise one of the substrates 2. As a result, the decorative board 3 is curved at a portion corresponding to the space between the substrates 1 and 2, and is bent into a shape in which the vertical surface 6 and the horizontal surface 7 are continuous through the corner portion 5 formed in this way.
In other words, a molded body is formed in which the vertical surface 6 and horizontal surface 7 of the decorative board 3, which are continuous through the arc-shaped corner portion 5, are lined with the substrates 1 and 2, respectively.
The pressing head 9 presses the decorative laminate 3 from the front side of the decorative laminate 3 in correspondence with the corner portion 5, and its tip forms an arc-shaped pressing portion 10. By pressing the corner portion 5 with this pressing portion 10, the shape of the corner portion 5 is adjusted.
One end of the pressing part 10 is connected to the substrate 1 between the horizontal base 18 and the horizontal base 18.
and the decorative board 3, and press the decorative board 3 against the edge of the substrate 1 facing the corner part 5. A pad 11 made of an elastic material such as rubber is fixed to the other end of the pressing part 10, and a substrate 2 and a decorative board 3 are sandwiched between this pad 11 and a vertical base 17. The decorative board 3 is pressed against the edge of the substrate 2 facing the corner.
By providing the pad 11 in this way, the pressing head 9 is formed at the end of the pressing part 10 on the pad 11 side.
A relief is formed between the and the decorative board 3, and
The decorative board 3 can be pressed against the edge of each board 1, 2 facing both ends of the corner part 5 by the pad 11 and the pressing part 10, and the decorative board 3 can press the board 1, 2 at this part.
