Description

The present invention relates to a method for producing a solid wood grain sheet substrate, that is, a thin and long tree trunk is completely obtained, and a membrane material is obtained by slicing it precisely according to the distribution characteristics of the wood grain, and a large area of the natural joint of the wood grain is obtained. Create a match to express the real wood grain. In addition, the industrial benefit of the sheet substrate is to achieve the practical benefit of conserving natural resources by cutting and applying it with high efficiency, especially due to the growth characteristics of wood, and minimizing the consumption.

The application of wooden building materials and boards to interior decoration wallboards and furniture not only gives the room a warm color texture, but also gives off a natural fragrance, making it the finest and most expensive material.

However, due to the slow growth rate of trees, using a large amount of whole solid wood (such as cedar and pine) as planks would destroy the global environment due to excessive logging. It is not easy to obtain solid wood, the price has soared, and the damage to nature has become so serious that it can never be ignored. For this reason, there are many substitutes such as plywood and foam board on the market today to replace the appearance of solid wood.

Commonly used plywood and foam boards have a wood-patterned skin attached to the outer layer, but the aforementioned skin was printed with a printer, so there were many overlapping patterns, and it was very unnatural when applied to decoration. In addition, the printed skin lacked the inherent ability of wood to absorb infrared and ultraviolet rays, lacked the natural warm color texture, and lacked the natural woody fragrance.

In order to solve the above problems, some manufacturers acquire natural wood veneers by processing lumber using techniques such as flat sawing, rotary cutting, quarter sawing, or thin slicing, and apply affixing treatment to obtain natural wood veneers. We have developed a wood grain sheet that can be attached to the outer layer of plywood or foam board or the upper layer of non-woven fabric.

However, the conventional veneer incision technology does not take into consideration the growth of the wood when obtaining the material, so when the wood grain board is pasted together as a whole, the natural wood grain will fall apart or burst. It was inevitable. In particular, when laying on a board surface or wall surface with a large size and a wide area, the above-mentioned manufacturing method causes the pattern to overlap or the pattern of the veneer to become extremely unnatural, and the installation effect of natural wood is lost. It was clearly not practical enough.

Another approach is to laminate a technological veneer to a plywood or rigid material. However, the veneer made by such science and technology requires pre-treatment before bonding, which complicates the process and increases the cost. was expensive and inconvenient.

Therefore, the present inventor thought that the above drawbacks could be improved. In other words, improving the above-mentioned veneer incision technology, obtaining materials with high efficiency, and protecting natural timber resources are the current issues that related businesses are actively aiming to solve together.

The present invention has been developed in view of the above technical problems, and an object of the present invention is to provide a method for producing a solid wood grain sheet base material. In other words, a waste part is partitioned at the center of the annual ring cross-section of a horizontally slender trunk, and the trunk is cut horizontally one by one with the same thickness to obtain a multi-layered plate, and then the top is cut. The material with a narrow bottom is removed, the left and right side surplus sides are removed, the waste part is cut vertically to excise, the thickness is the same and both sides have vertical joint surfaces, and the tree species is different. A multi-layered wide main board representing wood grain and a multi-layered narrow sapwood representing connecting vertical pattern features are cut out respectively. Here, a plurality of said mainboards and sapboards of the same length are selected and joined horizontally according to the overall demand of the total width, so that the length and width dimensions of the given sheet final product are substantially larger than the width and length. It constitutes a substrate that expresses large, natural wood grain joints. Square bars having substantially the same thickness as the substrate are attached to both sides of the substrate in the length direction, and the sides are sealed to form a membrane plate, and the membrane plate is thinly sliced horizontally to form a sheet. is being produced. A transparent adhesive is applied to the entire surface of a thin non-woven fabric, a non-woven fabric having substantially the same width is positioned on the bottom surface of the sheet, and the sheet and the non-woven fabric are firmly attached to form a substrate with wood grain distributed all over. is formed and subjected to molding treatment, and then the base material is cut into fixed dimensions in the vertical and horizontal directions to produce a sheet base material. It has a wide grain texture like natural raw wood, and in particular, each sheet substrate has the characteristic that the grain of natural solid wood never overlaps, which clearly enhances the application value of this kind of sheet substrate. .

Another object of the present invention is to provide a method of making a solid wood wood grain sheet substrate. In other words, the material is mainly obtained in the direction of growth of the natural wood grain of the tree, the center of the trunk where corrosion phenomenon is likely to occur is separated and eliminated as a waste part, and the narrow material on both sides of the top and bottom and the surplus on both sides of the top and bottom are removed. Mainboard and sapwood acquisition is completed after the edges have been cut to apply the available timber that forms the perfect grain with maximum efficiency. To achieve the practical benefit of progressiveness that reduces the occurrence rate of defects when joining wood grains in the processing process, simplifies the process, and enhances the economic effect.

Yet another object of the present invention is to provide a method of making a solid wood wood grain sheet substrate. In other words, there is a practical benefit in fully applying effective wood with high efficiency. To achieve the effect of reducing the quantity, reducing the amount of deforestation, and protecting precious natural resources.

Still yet another object of the present invention is to provide a method of making a solid wood wood grain sheet substrate. That is, it is sliced horizontally into thin sheets. The bottom surface of the sheet is adhered to the non-woven fabric with a transparent adhesive to form a substrate with wood grain distributed over the entire surface. A molding process produces a sheet substrate after cutting to a fixed size. When an extremely thin non-woven fabric forms a light-transmitting state, a part of the thin sheet substrate exhibits light-shielding properties, and the entire substrate is directly applied as a curtain sheet of a curtain, when the light source combined inside or outside irradiates, the raw wood The wood grain expresses natural halation throughout. This is another practical benefit of applying the solid wood grain sheet substrate according to the present invention.

Other features of the present invention will become apparent from the description of the specification and accompanying drawings.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that the embodiments described below do not limit the content of the present invention described in the claims. Moreover, not all the configurations described below are essential requirements of the present invention.

The method for producing the solid wood grain sheet base material of the present invention will be described in more detail with reference to FIG. Each step of the fabrication method is shown below.
Step A: Demarcate waste section 21 in the center.
Step B, cut horizontally to the same thickness layer by layer.
Step C, remove narrow strips 2C and excess sides 2D from the main board 22;
Step D, remove waste 21 and excess edge 2D from sapwood 23;
Step E, the substrate 3 joins the main board 22 and the sap 23;
Step F, the membrane plate 4 seals the sides of the square bar 31 on both sides of the substrate 3 in the longitudinal direction.
Step G, the sheet 41 thinly slices the membrane plate 4 in the horizontal direction.
Step H, the substrate 6 is formed by bonding the thin nonwoven fabric 5 to the sheet 41 with a transparent adhesive.
Step I, wood grain sheet 7 is cut lengthwise and widthwise of base material 6 to fixed dimensions.

The above steps complete the production of the solid wood grain sheet substrate. Stacking and flattening the wood grain sheets 7 and subjecting the surface of the base material 6 to physical treatment with lacquer or the like is a commonly used technique for treating various conventional thin films, and is not included in the scope of the present invention. , the description of which is omitted.

Referring to FIGS. 2, 3 and 4, in the method for producing a solid wood grain sheet base material according to the present invention, a rectangular or circular waste material is placed at the center of the annual ring cross-section of an elongated tree trunk 2 lying horizontally. A section 21 is partitioned. The upper and lower sides of the waste section 21 are defined as wide plate areas 2A, and the left and right sides of the waste section 21 are defined as narrow plate areas 2B.

The horizontal cutter S1 cuts the tree trunk 2 layer by layer in the horizontal direction with the same thickness set to obtain multi-layered plates, and then a plurality of plate materials obtained from the wide plate areas 2A on both the upper and lower sides of the waste section 21. , remove the narrow material 2C, which is a plate with insufficient width on both sides of the top and bottom, cut the left and right sides as straight sides, and remove the surplus sides 2D. It is cut as a multi-layered wide main board 22 (see FIG. 4) which has a vertical joint surface and expresses the grain characteristics of the tree species.

A plate material obtained from a narrow plate area 2B in the middle of the tree trunk 2 and an area including the waste part 21 was vertically cut by a vertical cutter S2 so as to remove the waste part 21, and the waste part 21 was excised. After removing the redundant side 2D by cutting both left and right sides as straight sides from the plate material, the width of the multilayer that has the same thickness and has vertical joint surfaces on both left and right sides and expresses the characteristics of the connection-like vertical pattern A narrow sapwood 23 is obtained.

As shown in FIG. 2, the vertical cutter S2 cuts the rectangular waste portion 21 vertically so as to partition it, which simplifies the cutting process but reduces the material acquisition rate (sapwood 23 width) can cause problems. As shown in FIG. 3, the vertical cutter S3 vertically cuts the circular waste portion 21 into sections, and in the cutting process, the actual waste portion 21 is cut into pieces based on the actual width. do. Although the number of cutting steps is large, it has a practical utility in that the material acquisition rate is high (the width of the sapwood 23 is wide).

Referring to FIG. 5, a plurality of mainboards 22 and sapwood 23 are selected, both of which are perpendicular to the right and left sides and which are cut to the same length, for example, the length of 8ft, that is, about 245cm. , the total width of the overall, e.g., 4ft width, i.e. set to about 122cm, horizontally bonded according to demand, substantially larger than the length and width dimensions of the given sheet substrate final product, natural It constitutes a substrate 3 that expresses a seam of natural wood grains. For example, the substrate 3 can be set to a plate with a width of 4ft and a length of 8ft.

Since the width of the naturally grown trunk 2 is not uniform and the width of the waste part 21 cannot be precisely set, the specifications of the width of each piece of the main board 22 and the sapwood 23 do not match precisely. In this case, a worker selects the same tree species with similar wood grains at the site, cuts out the main board 22 and the sapwood 23, joins the width, and makes the length and width substantially larger than the predetermined sheet base final product. do it.

As for the combination method, it is preferable to combine the main board 22, which expresses one or more wood grain characteristics, with the wood grain icon of the sapwood 23 having one or more vertical joint surfaces on the left and right sides.

All the mainboards 22 or all the sapwoods 23 are joined together to form a never-overlapping wood grain iconography feature of different styles.

Referring to FIG. 6, both sides of the substrate 3 in the length direction are bonded with square bars 31 having substantially the same thickness as the substrate 3 to seal the sides, and then move the entire membrane plate to be processed. 4.

Referring to FIG. 7, a multi-layer sheet 41 (margins 411 of square bars 31) representing a natural wood grain joint is produced by slicing the membrane plate 4 thinly in the horizontal direction using a horizontal direction cutting machine S4. is doing.

Referring to FIG. 8, the manufactured multi-layered sheet 41 is formed by stacking continuous layers first, and flattening the upper surface by pressing the upper surface with a heavy object W to facilitate the subsequent laminating operation.

Referring to FIG. 9, the transparent adhesive is applied to the entire surface of the thin non-woven fabric 5 by the adhesive application roller P for applying the transparent adhesive, and the non-woven fabric 5 of substantially the same width is positioned on the bottom surface of the sheet 41 in the upside-down state. 41 and the non-woven fabric 5 are adhered firmly together to form a base material 6 which is a wood grain flake with wood grain distributed over the entire surface.

Referring to FIG. 10, after the base material 6 is shaped, it is cut into fixed dimensions in the vertical and horizontal directions to naturally express the wood grain of a wide area like natural raw wood, and especially to bond the surfaces of various materials. It has a wood grain sheet 7 that can be constructed by

The wood grain sheet 7 has a non-woven fabric 5 laid on the bottom layer to facilitate the application of adhesive, and is used as a wall surface, a blanket curtain, or a piece of furniture. The substrate that is attached and applied to the surface of the equipment expresses the texture of the wood grain over a large area, achieving the features of the present invention of significant economic benefit and reliable inventive step.

The above description is for the purpose of illustrating the present invention and should not be construed as limiting the invention described in the claims or restricting the scope thereof. Further, the configuration of each part of the present invention is not limited to the above-described embodiment, and of course various modifications are possible within the technical scope described in the claims.
