Description

The present invention relates to a decorative panel that can be suitably used as a decorative wall material such as an interior wall material of a general house, and a method for manufacturing the decorative panel.

Many wood decorative panels used as indoor decorative wall materials have a constant cross section orthogonal to the longitudinal direction, and are formed so as to have the same cross-sectional shape at any position in the longitudinal direction (Patent Document 1, etc.). ). In such a wood decorative panel whose cross-sectional shape does not change, for example, a panel material such as a plate-shaped laminated wood is conveyed in the longitudinal direction and passed through a cutting tool arranged corresponding to a processed surface such as the surface of the panel material. Therefore, it is generally manufactured by using a moulder or the like configured to process the surface or the like in a concave portion.

On the other hand, in recent years, in order to further improve the design, the wood decorative panel has a shape such that the surface (decorative surface) has irregularities along the longitudinal direction, that is, the cross-sectional shape differs depending on the position in the longitudinal direction. Has been proposed. It is difficult to manufacture such a wood decorative panel having irregularities along the longitudinal direction with the above-mentioned ordinary moulder or the like. Therefore, in order to manufacture a wood decorative panel having such a shape, for example, it is processed by hand or along the longitudinal direction with a three-dimensional processing machine such as an NC processing machine in which the cutting tool moves three-dimensionally with respect to the panel material. It is customary to process in a discontinuous manner.

Here, in FIG. 1B, the dimension on the drawing is set to 8/100 with respect to the actual dimension, and the omitted portion shown by the alternate long and short dash line is 100 mm on the drawing. Further, in the wood decorative panel P1 of the present embodiment, the end face on the left side (the other side) is symmetrical with the end face on the right side (one side) (see FIG. 1C). The conditions related to these drawings are the following FIGS. 2A to 2E, FIGS. 5A to 5F, FIGS. 6A to 6E, FIGS. 7A to 7E, FIGS. 8A to 8E, FIGS. 9A to 9E, and FIGS. 10A to 10A. The same applies to FIGS. 10E and 11A to 11E.

Further, in the present embodiment, the longitudinal direction corresponds to one direction and the width direction corresponds to the other direction.

As shown in FIGS. 1A to 1F, the wood decorative panel P1 of the first embodiment is formed so that the cross-sectional shape orthogonal to the longitudinal direction is different depending on the position in the longitudinal direction. Further, the wood decorative panel P1 is divided into three at substantially equal intervals in the width direction, so that three continuous parallel regions 2 in the longitudinal direction are arranged in parallel in the width direction. A vertical groove 3 continuous in the longitudinal direction is formed between the adjacent columnar regions 2 and 2 on the surface of the wood decorative panel P1, and a chamfered portion 3a continuous in the longitudinal direction is formed on both side edges of the surface. ing. When the wood panels P1 are arranged along the width direction, vertical grooves are formed by the chamfered portions 3a, 3a of the wood panels P1 and P1 adjacent to each other in the width direction.

In the cross section (longitudinal cross section) orthogonal to the panel width direction shown in FIG. 1F, in each parallel region 2, convex portions 21 having a flat top and concave portions 25 having a flat bottom are alternately arranged along the longitudinal direction. ing. Therefore, the surface of the wood decorative panel P1 of the present embodiment is formed in a substantially angular wave shape in which convex portions 21 and concave portions 25 are repeatedly formed along the longitudinal direction in each parallel region 2.

Further, in the present embodiment, for example, one unit processing pattern 20 is formed by the convex portion 21 and the concave portion 25 adjacent thereto. In other words, in each parallel area 2, a pattern (shape) having a unit processing pattern 20 as one cycle is continuously formed while repeating in the longitudinal direction.

Further, in the present embodiment, the unit processing patterns 20 and 20 adjacent to each other in the width direction are arranged so as to be displaced by 1/3 cycle in the longitudinal direction. Specifically, the unit machining pattern 20 in the middle of the width direction is displaced by 1/3 cycle to one side in the longitudinal direction with respect to the unit machining pattern 20 at one end in the width direction, and the unit machining pattern 20 in the middle in the width direction is displaced. On the other hand, the unit processing pan turn 20 at the other end in the width direction is displaced by 1/3 cycle to one side in the longitudinal direction.

Further, in the present embodiment, the male fruit portion 4a is formed on one side edge portion (upper edge portion) of the wood decorative panel P1, and the female fruit portion 4b is formed on the other side edge portion (lower edge portion). It is formed.

In the present embodiment, as the material (panel material) for the decorative panel, a wood-based material, a nitrogen-based material, a resin-based material, a gypsum board-based material, or a composite thereof can also be used. As the wood-based material, solid wood, laminated wood, MDF, plywood and the like can be used. As the nitrogen-based material, a cement plate or the like can be used. As the resin-based material, a resin plate, a wood powder plastic plate, or the like can be used.

In the present invention, those made of these materials may be used as a decorative panel, or these materials may be used as a base material and a decorative material laminated on the base material may be used as a decorative panel. good.

In particular, in the present invention, as the material (panel material) of the wood decorative panel P1, a material in which a decorative material is laminated on a base material of a wood-based material can be preferably used. As the decorative material, a sawn board or the like can be preferably used. The thickness of the decorative material is preferably set to 3 mm or more, more preferably 5 mm or more. If the thickness of the decorative material is too thin, the base material may be exposed due to the uneven processing (concave processing) of the surface, which is not preferable.

The species of the base material in the panel material is not particularly limited, but when a tree species having a straight grain such as a conifer is used, the surface unevenness processing causes a natural change in the grain, so that the conifer is used. It is preferable to use it.

When the width stripped laminated lumber is used as the base material of the panel material, the width of the block material joined in the width direction preferably matches the width of the parallel area 2 (unit processing pattern 20), but does not necessarily match. No need.

In the present embodiment, the wood decorative panel P1 has a size of 2730 mm in length, 176 mm in width, and 16 mm in thickness. Needless to say, in the present invention, the size of the wood decorative panel P1 is not particularly limited, and for example, one having a length of 1820 mm can also be used.

In the first embodiment, the above-mentioned wood decorative panel P1 is manufactured by performing moulder processing as cross-sectional shape processing and three-dimensional processing as discontinuous recess processing as described below. There is. In this embodiment, the moulder processing corresponds to the primary processing, and the three-dimensional processing corresponds to the secondary processing.

FIG. 3 is a block diagram schematically showing a moulder (moulder processing machine) 5 for performing moulder processing when manufacturing the wood decorative panel P1. As shown in the figure, the moulder 5 is provided with a transport means (not shown) for transporting the panel material 10 at a constant speed along the longitudinal direction as shown by the arrow symbols in the figure. Further, the actual machining blades 51 and 51 as the cross-sectional shape machining blades are arranged corresponding to the both side edges of the panel material 10 to be conveyed, and the surface as the cross-sectional shape machining blade corresponds to the surface. A cutting tool 52 for processing is arranged.

In the present embodiment, the blades 51 and 52 are composed of, for example, one circular saw or a plurality of stacked circular saws.

Then, in the present embodiment, the panel material 10 is conveyed in the longitudinal direction by the conveying means, and the regions of both side edges and the surface portion of the panel material 10 are rotationally driven to drive the actual machining blades 51, 51 and the surface machining. It is processed by passing it through the blade 52.

2A to 2E are views showing an intermediate product 11 which is a panel material immediately after being primary processed by the moulder 5. As shown in these figures, the intermediate product 11 has a cross-sectional shape orthogonal to the longitudinal direction having the same cross-sectional shape at any position in the longitudinal direction, and has irregularities on the surface along the longitudinal direction. It has a shape that does not. Specifically, the intermediate product 11 has a male fruit portion 4a and a female fruit portion 4b formed on both side edges thereof. Further, by forming the vertical groove 3 and the chamfered portion 3a on the surface of the intermediate product 11, three vertical columns regions 2 are formed.

In the present embodiment, only the vertical groove 3 and the chamfered portion 3a are removed from the surface of the intermediate product 11, and the other portions are substantially unprocessed. Therefore, in each parallel region 2, a continuous convex portion 22 having a flat top is continuously formed in the longitudinal direction.

FIG. 4 is a block diagram schematically showing an NC processing machine 6 for performing three-dimensional processing (discontinuous recess processing) when manufacturing the wood decorative panel P1. As shown in the figure, the NC processing machine 6 includes an installation table 61 for installing the intermediate product 11 and an arm 62 arranged on the surface side of the intermediate product 11. The installation table 61 is provided with a suction means 61a, and the panel material 10 such as the intermediate product 11 can be installed horizontally through the suction means 61a, and the installed intermediate product 11 is sucked. It is configured so that the position can be fixed by air adsorption or the like by the means 61a. A circular saw, a router bit, or other cutting tool 63 (circular saw in this embodiment) that constitutes a cutting tool for discontinuous recess processing is attached to the tip of the arm 62. Further, the arm 62 is configured such that its tip portion (cutting tool 63) can be moved in a three-dimensional direction by a three-dimensional moving means (not shown), and the cutting tool 63 can rotate at high speed.

In the present embodiment, the circular saw used as the cutting tool 63 has a width equal to the width of each parallel area 2 and has a flat cutting shape.

Then, by moving the blade 63 in the three-dimensional direction with respect to the intermediate product 11 while rotating the blade 63 at high speed, the required region of the surface portion of the intermediate product 11 is removed, and the wood decorative panel P1 is manufactured. Specifically, in the vertical cross section orthogonal to the panel width direction, the portion of the continuous convex portion 22 excluding the flat tip portion (top) of the convex portion 21 by the NC processing machine 6 with respect to the intermediate product 11, that is, The portion from both the front and rear slopes of the convex portion 21 to the entire inner circumference of the concave portion 25 is removed. As a result, as shown in FIGS. 1A to 1F, the wood decorative panel P1 having the above-mentioned structure having irregularities on the surface portion along the length direction is produced.

In this embodiment, three-dimensional machining is performed by the NC processing machine 6 for each parallel area 2 of the intermediate product 11.

In the method for manufacturing a wood decorative panel of the present embodiment, the panel material 10 is subjected to moulder processing (primary processing) with a moulder 5 to form the panel material 10 into a constant cross-sectional shape to produce an intermediate product 11. Since the intermediate product 11 is subjected to three-dimensional processing (secondary processing) by the NC processing machine 6 to produce the wood decorative panel P1, the wood decorative panel P1 having an uneven shape along the longitudinal direction is formed. It can be reliably produced.

In addition, since the main part of the panel material 10 is removed by high-efficiency moulder processing and the remaining finished part is removed by three-dimensional processing, the amount of processing by low-efficiency three-dimensional processing can be reduced as a whole. Work efficiency can be increased, production efficiency can be improved, and costs can be reduced.

For reference, in the manufacturing method of this embodiment, the wood decorative panel P1 as described above has a total processing time of about 10 minutes, which is a total of about 10 minutes of moulder processing of about 30 seconds and NC processing (three-dimensional processing) of about several minutes. Can be produced. On the other hand, for example, if the above-mentioned wood decorative panel P1 is to be manufactured only by NC processing, a processing time of 30 minutes or more is required. Moreover, if it is cut by hand, the processing time will be longer. As described above, in the manufacturing method of the present embodiment, the wood decorative panel P1 can be efficiently manufactured.

Further, in the present embodiment, since the finish processing (secondary processing) is performed by NC processing that can be processed with high accuracy, the processing accuracy can be improved and high commercial value can be obtained.

Furthermore, in the present embodiment, since NC processing is performed for each parallel area 2 of the wood decorative panel P1, it is possible to reduce the movement of the cutting edge of the NC processing machine in the width direction of the floor material. The processing accuracy can be further improved.

Further, in the present embodiment, since the vertical groove 3 is formed between the adjacent column areas 2 and 2, when the boundary portion between the adjacent column areas 2 and 2 is processed by the NC processing machine, the NC processing machine is used. The cutting edge can be accurately brought into contact with a predetermined machining area through the vertical groove 3, and it is possible to reliably prevent machining defects such as fluffing and misalignment of machining positions at the boundary portion.

In the above embodiment, a moulder 5, which is a kind of a pan, is used as a processing machine for processing a cross-sectional shape, but the present invention is not limited to this, and in the present invention, the panel material is orthogonal to the longitudinal direction. Any processing machine that can continuously form a cross-sectional shape (cross-sectional shape) with a constant shape in the longitudinal direction can be used as a processing machine for cross-sectional shape processing. For example, a planer such as a planer, a circular saw and a wood saw such as a grooving machine, a chamfering machine and a router, a wood milling machine such as an NC processing machine, and a processing machine such as a sawing machine such as a tenor can also be used. ..

However, in the present invention, the panel material is moved in the longitudinal direction with respect to the fixed blade as compared with a processing machine such as a grooving machine in which the blade is moved in the longitudinal direction with respect to the fixed panel material. Since the moulder or the like of the above embodiment can be processed more efficiently, it is preferable to use a processing machine such as a moulder or the like in which the material (panel) side is moved in the cross-sectional shape processing.

Further, in the above embodiment, an NC processing machine is used to perform three-dimensional processing (discontinuous recess processing), but the present invention is not limited to this, and in the present invention, the surface of the panel material is discontinuous in the longitudinal direction. Any processing machine capable of forming a recess can be used as a processing machine for discontinuous recess processing. As a processing machine other than the NC processing machine, a multifunctional sander and a multifunctional moulder can be exemplified. In the multi-function sander and multi-function moulder, a plurality of blades are arranged in the width direction and the longitudinal direction on the panel material surface side, and each blade is configured to be movable in the direction (vertical direction) in which each blade is in contact with and separated from the panel material surface. While transporting the panel material in the longitudinal direction, each blade is moved up and down (moving in contact with and detached from) with respect to the surface of the panel material to form a non-continuous recess in the longitudinal direction on the surface of the panel. It is processed into a shape with irregularities along the longitudinal direction. As described above, the present invention is not limited to the three-dimensional processing machine that moves the cutting tool in the three-dimensional direction with respect to the panel material, and has a multifunctional function capable of moving the cutting tool at least in the longitudinal direction and the contact / separation direction (vertical direction). Any processing machine such as a sander or a multifunctional moulder can be adopted as a processing machine for discontinuous processing.

However, in the present invention, it is preferable to use an NC processing machine such as the above-described embodiment, which has higher processing accuracy than a multifunctional sander or a multifunctional moulder.

Further, in the above embodiment, the cross-sectional shape processing is performed and then the discontinuous recess processing such as three-dimensional processing is performed. However, in the present invention, the cross-sectional shape processing is performed after the discontinuous recess processing is performed. You may do it. However, in the present invention, when performing three-dimensional processing such as NC processing, by forming a vertical groove or the like in advance, the three-dimensional processing can be performed more accurately, so that the cross section is as described in the above embodiment. It is preferable to perform three-dimensional processing after performing shape processing.

Further, in the above embodiment, when performing discontinuous recess processing such as three-dimensional processing, processing is performed one row at a time for each of a plurality of column regions 2 of the intermediate product 11, but the present invention is not limited to this. May process three rows (all rows) in parallel. Further, as shown in the embodiment described later, when six column regions 2 are formed in the intermediate product 11, two rows are processed in parallel, or three rows are processed in parallel. , All rows may be processed in parallel.

Further, in the above embodiment, the case where the longitudinal direction is one direction and the width direction is the other direction has been described as an example, but the present invention is not limited to this, and in the present invention, the width direction is one direction and the longitudinal direction is the other direction. You may try to. Specifically, in the above embodiment, a case where the cross section orthogonal to the longitudinal direction is formed to be constant in the cross-sectional shape processing and the recesses discontinuous in the longitudinal direction are formed in the discontinuous recess processing is given as an example. However, the present invention is not limited to this, and in the present invention, the cross section orthogonal to the width direction is formed to be constant in the cross-sectional shape processing, and the non-continuous recess is formed in the discontinuous recess processing. May be.

Further, in the above embodiment, the case of manufacturing a rectangular decorative panel has been described as an example, but the present invention is not limited to this, and the present invention can also be applied to the case of manufacturing a square decorative panel.

Needless to say, the blade for cross-sectional shape processing and the blade for discontinuous recess processing include materials used for decorative panels, such as wood-based materials, ceramic-based materials, resin-based materials, and gypsum board-based materials. By using a cutting tool suitable for, it is possible to process without any trouble.

<Second Embodiment>
Next, a case where the wood decorative panel P2 of the second embodiment in which the second pattern is formed is manufactured by the method for manufacturing the wood decorative panel of the present invention will be described.
