Description

FORMATION MANUFACTURING METHOD OF STRUCTURE OF TREE}

The present invention relates to a method for processing wood grain, and more particularly, when forming a ring-shaped uneven pattern such as natural aging, to fully reproduce the knot part, to enhance the natural beauty, full of profound and deep classic decoration The present invention relates to an improved method for processing wood texture.

In general, the plasterboard, such as floorboards, wallboards or other flat plywood for furniture was used to adhere the natural veneer to the plywood or plate to obtain a natural wood effect.

By the way, such plasterboard should be made separately to attach the veneer to the surface of the wood board, so the cost of manufacturing natural veneer increases, and not only takes a long time, but also requires a separate attachment process to increase the labor of work. There were many inconveniences and disadvantages.

In addition, there is a defect that the natural veneer peels off from the plate when aging for a long time even after manufacturing the plasterboard with natural veneer.

Thus, in order to improve this, as shown in Figure 1 (a), when burning the surface of the wood 10 with a torch or the like, the soft portion 20 easily rides, the hard portion 30 is slow to burn using the characteristics of the bone and There is an example in which the uneven pattern having a hill is artificially formed to have natural beauty such as wood grain, shape and touch unique to wood.

As another example, there is an example in which the uneven pattern is artificially imprinted by forcibly pressing the surface of the wood using a compressed roller inscribed with the uneven pattern in yin and yang.

By the way, in the former case, the pattern is well formed and not formed well depending on the type of wood, and because the wood is burned by the thermal power, there was a drawback that the clear pattern was not obtained.

In addition, in the latter case, since the same pattern of the pressing roller is engraved, the pattern is monotonous, and it is difficult to express natural beauty.

In view of such drawbacks, recently, examples such as Patent Registration No. 0424789 and Patent No. 0664549 have been disclosed, in which torch and brush are polished in parallel to further enhance antique and natural beauty, and then use paraffin to improve the vividness of a pattern. In addition, brush polishing and sand paper are combined to form a natural weathering pattern to create a luxurious and old-fashioned aesthetic, and a separate coating is applied to protect the surface. An example has been disclosed to show an elegant and beautiful color.

However, as shown in (b) of FIG. 1, in these cases, the knot 40 resulting from the wound of the wood has a substantially concentric shape, and thus the knot 40 is brushed in the longitudinal direction of the wood 10. The part has a limitation in that it cannot form irregularities.

In addition, there is no processing device that can be freely changed according to the demand of the user to process such natural beauty patterns in various ways. There is a need for an acceptable processing method.

In addition, the above-described bar can be regarded as the same in plate-shaped wood, as well as in lumber, circular pillars and the like.

The present invention was created in order to solve all the problems of the prior art as described above and to meet the need for improvement, and to process the surface of the wood to have the same shape as natural veneer, but easily variable according to the choice of demand It is possible to produce various kinds of veneers through the same processing equipment, and in particular, natural patterns with clear irregularities are processed on the knots, thus providing a method of processing wood textures that completely eliminates artificial beauty and maximizes natural beauty. There is a purpose.

The present invention is a means for achieving the above object,
What is claimed is: 1. A method for processing a surface of wood lumbered in a wood grain direction to form a grain pattern having a light gray difference; A first step of lifting the wood for the surface processing with a wood lifter and seating on the upper surface of the work bench is installed dust collector; A second step of forming an uneven pattern by using a hand brush provided with a brush for radially rotating a knot portion formed in a concentric shape of wood seated on an upper portion of the work table; After the second step, a third step of cutting the hard part and the soft part of the wood surface by brushing the surface of the wood using a hard brush roll while transferring the wood to the roller table; After the third step, the fourth step of shaking off the wood powder shaved by the brush roll using a cleaning roll so that the wood grain pattern of the wood is clearly visible; A fifth step of burning the surface of the wood using a torch after the fourth step; After the fifth step, a sixth step of spraying and naturally drying the coating liquid through a coating nozzle to coat a matte protective film protecting the surface of the wood; After the sixth step, using a secondary and tertiary coating unit consisting of a spray nozzle for spraying UV paint and UV lamp for curing and drying the UV paint to perform the intermediate and top coat coating of the gloss state on the surface of the wood Step 7; After the seventh step, and the eighth step of attaching a protective sheet through the lapping roll on the surface of the wood; provides a method of processing a pattern of wood, characterized in that consisting of.

According to the present invention, the surface of the wood can be processed almost close to the natural pattern produced by natural weathering, automation is possible, productivity is improved, and even if automated, partial process change is possible according to the demand of the demand. Through the processing equipment of the can obtain the effect of forming a variety of natural patterns.

1 is an exemplary view of a wooden board processed natural pattern on the surface according to the prior art.
2 is a schematic configuration diagram of a processing apparatus according to the present invention.
Figure 3 is a schematic illustration showing a processing example of the lumber or circular pillar of wood processed according to the present invention.
Figure 4 is an exemplary view of the wood processed natural texture on the surface in accordance with the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

As shown in Figure 2, the pattern processing apparatus for wood according to the present invention is roughly divided into the part to perform the basic process and the part to perform the selection process, a number of components that can be selectively processed during the basic process may be included.

That is, the basic process according to the present invention consists of kneading, roll brushing, washing brushing, burning (burning), paint coating, and drying.

In order to perform such a process, the processing apparatus according to the present invention includes a wood lifter (100).

The wood lifter 100 is a kind of lifting means provided to be pulled out one by one while working in the state of placing a plurality of wood 110 for surface processing to the work table (W).

The workbench W will be sequentially transported to the roller table 130, as shown in the circle to expand the wood 110 is drawn one by one, the process for processing the knot portion is performed.

That is, in the present invention for processing the knot part, the hand brush 120 is installed on the work table (W).

The hand brush 120 is to form an uneven pattern in the knot 112 (see Fig. 4) formed concentrically through a brush rotating in the radial direction.

That is, because the conventional brushing only in the longitudinal direction of the wood 110, it was not possible to form the uneven pattern for the knot 112 formed concentrically.

Therefore, in the present invention, before the wood 110 is processed in the longitudinal direction, the worker first inspects with the naked eye, and if there is the knot 112, the knot 112 is first brushed with a hand brush 120 to maintain the knot 112. The uneven pattern is sharply formed first on the part and then configured to start the longitudinal processing.

At this time, although not explicitly shown in the drawing, depending on the material (hard, soft, etc.) of the wood 110 or the type of wood 110 (coniferous, hardwood, etc.), the knot part is processed into a desired shape only by the hand brush 120. In consideration of this, it may be configured to process the knots more easily by carbonizing in advance with a strong fire using a torch (PT) before processing the hand brush 120.

In addition, when brushing with the hand brush 120, fine dust is scattered and may damage the environment as well as environmental pollution, so to prevent this, a dust collector 152 is installed on the upper part of the work table (W) to collect dust. More preferred.

In addition, the roller table 130 is arranged in the horizontal direction on the adjacent side of the work table (W) is configured to smoothly transport the wood (110).

At this time, the processing apparatus according to the present invention may form a closed space in the upper and lower chamber form around the roller table 130, but only the main points of the present invention will be described with respect to the open state in the illustrated example.

In addition, the processing apparatus according to the present invention, such as brush roll 140, washing roll 150, torch 160, the coating nozzle 170, etc., the upper or lower, upper and lower with respect to the roller table 130 The lower portion of the roller table 130 may be sequentially installed in both directions.

In particular, when the brush roll 140 or the washing roll 150 is installed only on the upper side, it is preferable that a pressurizing roller that can support the lower side is provided to provide a sufficient pressing force. Since the weight of the wood 110 itself is sufficiently pressurized by its load, there is no need to put a pressure roller in the upper part.

Here, the brush roll 140 is made of a hard like a steel brush, and when the wood 110 is transported along the roller table 130 to brush the surface at high speed to the hard portion of the surface of the wood 110 and The soft parts are scraped differently.

In this case, since the wood 110 is usually lumbered in the direction of the wood grain, the wood grain is formed in the longitudinal direction of the wood 110, and the hard part and the soft part are cut out differently by the brush roll 140. As a result, natural patterns such as natural weathering are formed.

In addition, the washing roll 150 is a means for washing the wood powder shaved by the brush roll 140 so that the wood grain pattern is more clearly exposed.

At this time, the dust collecting duct 152 is connected to the upper portion including the brush roll 140 and the washing roll 150 to suck the wood powder scattered to prevent floor contamination in the installation place, and to protect the health of the worker desirable.

In addition, the torch 160 is disposed after the washing roll 150 when viewed in the direction in which the wood 110 proceeds. In the past, the torch 160 was burned and brushed using the torch 160 first so that a deep and profound feeling was felt. Although it could not be properly saved, in the present invention, since the brushing and washing have been completed, that is, a sufficient natural pattern has already been formed so as to give an old fashioned look, a deeper and profound fashion can be achieved.

The torch 160 may use the same as the conventional one.

And, as a final configuration belonging to the basic process, there is a coating nozzle 170, the coating nozzle 170 is a spray coating method to use as a coating for protecting the protective film to protect the surface of the wood (110). Reasonable.

Here, the undercoat is the most basic coating, and can be regarded as a coating that makes full use of natural beauty.

In addition, it is also a means for maintaining the gloss on the surface of the wood 110, the coating liquid sprayed through the coating nozzle 170, as is well known, varnish, lacquer, pigment, enamel, paint, lacquer, poly Preferred are urethane paints, polyester paints, amino alkyd paints, acrylic paints and the like.

In addition, when the application of the coating liquid is completed, the drying is performed, the drying is preferably natural drying at room temperature, it can be heat-dried through the heating means as necessary.

Such a basic process is a process that is applicable when the demand price wants to keep the feeling of wood as it is, and in this state, the process may be finished and shipped as a product.

In addition, several additional facilities may be added to satisfy the various needs of the demand among the basic processes, such as a preliminary torch (T) and sandpaper (S).

The preliminary torch (T) is preferably installed between the hand brush 120 and the brush roll 140, which has a variety of different strengths, such as conifers, deciduous trees, etc., depending on the wood 110, or burn easily Because there are various forms such as not burning, in some cases, the desired pattern may not be obtained by only one burning using a torch.

Therefore, in this case, the preprocessing is performed through the preliminary torch T, and the main processing is performed through the torch 160 to completely implement a desired shape.

At this time, if the carbonization of the wood (110), as described above, if the carbonization is performed in advance with the torch (PT) before the hand brush 120, it is not necessary to perform the recarbonization through the preliminary torch (T). If not, further carbonization via a preliminary torch (T) can be carried out, which is optional.

In addition, the sand paper (S) is formed in a roll type, the surface may be roughened depending on the type, material, moisture content, dry state, etc. of the wood 110, the polishing surface according to the selection to prevent this in advance It can be used to finish and polish more finely and beautifully, which is also optional.

In addition, before and after the points where the respective components are installed, by placing a sensing means such as a light sensor so as to grasp the movement of the wood 110, the moment the object is confirmed that the wood 110 is entered (blush roll, washing Roll, torch, coating nozzle, etc.) can be controlled to operate, thereby enabling efficient operation and automatic control of the device.

On the other hand, the selection process is a process that is selectively performed according to the demand of the demand after the above-described basic process, and includes a middle coating (secondary coating), top coating (third painting).

In other words, the product that has undergone the basic process is in a matt state (primary coating), and through the selection process, it becomes a glossy state (secondary or tertiary painting).

In particular, in the present invention, it is preferable to adopt a curing and drying method using ultraviolet rays for the gloss.

In this case, the secondary coating unit 200 may be cured and dried in a medium-coated state to produce a product, and the third coating unit 210 may be cured and dried in a rough top-coated state to produce a product.

In this case, the secondary paint units 200 and 210 include spray nozzles for spraying UV paint, and UV lamps for curing and drying the UV paint applied to the surface of wood 110.

By going through such a selection process, the gloss effect due to the gloss is maximized, so that the desired process can be performed according to the selection of demand.

Thereafter, the protective sheet 230 is finally attached to the surface of the processed wood 110 through the lapping roll 220 to be commercialized.

On the other hand, the wood 110 according to the present invention may be the same plate as the example described above, it may also be a lumber (110 ') as shown in Figure 3 (a).

If the corner member 110 ′, four brush rolls 140 may be installed in the illustrated form so as to brush at least four sides.

In this case, not only the brush roll 140 but also other components (equipment) required for processing may be arranged in such a form.

In addition, as shown in (b) of FIG. 3, if the circular pillar 110 (110 ") is preferably arranged by processing the brush roll 140 as close to the circle as possible, processing by arranging to form an octagon as shown in the example shown Ham is the most reasonable.

Therefore, the processing apparatus according to the present invention is capable of processing not only a plate but also a square material, a circular pillar, and the like, and therefore, the application range is expected to be very wide and useful.
