Description

Apparatus and method for manufacturing a veneer panel having a complex yin-yang pattern {APPARATUS AND METHOD FOR FABRICATING A VENEER PANEL HAVING COMPLEXED INTAGLIO AND RELIEF PATTERN}

The present invention relates to an apparatus and a method for manufacturing a veneer panel which forms a complex yin relief pattern by applying a level scraping process and a panel leveling process together.

Since ancient times, wood has been used as a material that has a very close and intimate relationship with humans. High-grade wood has been spotlighted for its interior and furniture materials because of its excellent texture and aesthetics, but it was not economical due to its disadvantages such as deformation and warpage and expensive cost. Meanwhile, boards and veneers have replaced many of the logs. Many veneers have been improved and evolved from natural veneers to aggregate veneers (or artificial veneers) and dyed veneers.

Bonding veneer to the base plate is called plastering, the thickness of veneer is 0.18mm ~ 0.3mm is wet plastering method, 0.35mm ~ 0.5mm is processed by dry plastering method. Mostly monotonous flat processing was mainly due to the weakness of the veneer, which is easily torn, broken or damaged. However, the impregnated nonwoven fabric is placed on the back of the veneer so that it can be processed into curved and uneven surfaces. In this method, the yin-embossed surface obtained after NC (Numerically Controlled Lathe) processing was bonded with a veneered veneer using a membrane (vacuum thermocompression bonding method) or a thermocompression mold. Since the Yin-Yang pattern panel is thin, it is easy to process the adhesive, so it requires a base plate with even surface to be bonded. Therefore, most of the medium-density fiberboard (MDF) with good physical properties and fine particles are obtained after NC processing. It was used as. In particular, only thick and high specific gravity MDFs were possible due to fear of bending. In addition, in the finishing of the edges, it is difficult to be compatible with the edge bender, which is the existing woodworking infrastructure, and there is often a partial peeling (lifting) and veneer burst after the adhesive finish. Due to these shortcomings and limitations of the substrate and the application field, the veneer is not widely used.

The controller controls the driving timing and the speed of each of the scraper 11, the brush devices 12 and 13, the pressure level device 30, the slider 21, the hydraulic drive device, and the up and down control device 31. The controller may be implemented as a programmable logic controller (PLC).

In order to process the large veneer panel 100, the scraper 11 must be as long as that. In this case, the depth of the intaglio pattern processed on the veneer panel 100 may vary due to the center portion of the scraper 11 being drooped, and the surface of the veneer panel may be unevenly processed during panel leveling. In order to prevent this, the scraper 11 may be divided into two or more as shown in FIGS. 5A and 5B. At least one side of the divided scrapers 11 overlap each other.

An example of the veneer panel 100 is, as shown in Figure 6, the first and second surface material (101, 103), the adhesive for bonding the surface material (101, 103), adhesive impregnated non-woven fabric or resin impregnated paper 102 And a base plate material 104 to which the second surface material 103 is bonded, and a balance surface material 105 for preventing warpage adhered to the back surface of the base plate material 104.

It should be noted that the structure of the veneer panel 100 is not limited to FIG. 6 because it can be variously modified according to a desired veneer pattern. The surface materials 101 and 103 and the bending preventing balance surface material 105 may be adhered to the base plate 104 by an adhesive, an adhesive impregnated nonwoven fabric, or a resin impregnated paper.

It is possible to implement the exposed complex yin-yang pattern. According to the cutter shape of the scraper 11, the intaglio patterns can be expressed in various forms as shown in (a) to (c) of FIG.

The present invention can fill the eco-friendly natural material in the intaglio pattern of the multi-layer veneer panel (100, 200).

9 and 10, in the method of manufacturing the veneer panel, the intaglio pattern 51 is formed on the base plate 104 using the scraper 11. (S1) The scraper 11 is intaglio as shown in FIG. 10. The intaglio pattern 51 is formed by using a cutter corresponding to the pattern 51 and a protrusion 52 having a height lower than the depth of the intaglio pattern 51 is formed in the intaglio pattern 51. The protrusion 52 may be formed in one or more according to the width and depth of the intaglio pattern 51, the thickness and height may be adjusted. The intaglio pattern 51 and the protrusion 51 may be simultaneously formed by the uneven cutter 11a of the scraper 11.

Subsequently, the manufacturing method of the veneer panel coats the coating agent 53 on the base plate 104 on which the intaglio pattern 51 is formed. (S2) The coating agent is a base plate 104 due to moisture absorption with a paint such as a primer. ) To prevent corrosion, swelling, deformation, etc. and to enhance the adhesion of the filler to be filled in the intaglio pattern (51).

Subsequently, in the method of manufacturing the veneer panel, the filler 60 of the eco-friendly material is filled in the intaglio pattern 51 of the base plate 104 by using a doctor blade or a printing rolling device. (S3) The filler 60 after the drying process. In order to prevent the thickness variation of the filler 60 due to the depression of the thickness of the filler 60 is applied to a thickness thicker than the depth of the intaglio pattern 51.

When the total weight ratio of the filler 60 is 100% by weight, 40% by weight to 70% by weight of eco-friendly natural materials, 15% by weight to 25% by weight of water, 5% by weight to 15% by weight of adhesive, 5% by weight of crack inhibitor 17 weight%, 0.5 weight%-3 weight% of water-soluble cellulose derivatives which are viscosity enhancers (thickeners), 0.2 weight%-1.0 weight% of water repellents, 0.05%-1.0% of a hardening accelerator, and 0-3 weight% of a coloring agent. Here, eco-friendly natural materials are ocher, white earth, brown earth, black earth, kaolin, diatomaceous earth, charcoal, germanium, silicon, calcium, magnesium, manganese, gold powder, silver powder, brass powder, pearl powder, gem powder, jade powder, ganban stone , At least one or more of coffee beans. The color of the filler 60 may be more than 98% colored by an environmentally friendly natural material, and the color tone may be adjusted by a trace amount of a colorant. Filler 60 may further include 2% to 6% by weight of at least one or more of the cheongung, Angelica, wormwood, pine needles, rosin powder (or rosin diluent), which is a material for adjusting the color and the beneficial components are discharged to the human body have.

Another embodiment of the filler 60 may include a lumber. The lumber is made of natural wood, aggregated wood (or artificial patterned wood), decolored / dyed patterned wood higher than the depth of the intaglio pattern 51 in the same manner as the width of the intaglio pattern 51.

Subsequently, the manufacturing method of the veneer panel is any one of a polypropylene (PP) film, a polyethylene (PE) film, a polyvinyl chloride (PVC) film, a release paper (or a release paper), and a leaf paper. Is laminated on the filler (60) and naturally dried for 12 to 36 hours at room temperature with a cold press, and depending on the material blending ratio, the panel using a T-shaped interlayer separation bar of a certain standard It is inserted in between and exposed to the load air and dried. (S4)

Subsequently, the panel 200 filled with the filler 60 is introduced into the panel leveler to grind and polish the filler 60 protruding above the surface to planarize the surface of the panel, thereby exposing the surface of the base plate 104 to be described later. Peeling of the surface material 103 is prevented. (S5) At this time, the cutter of the scraper 11 uses a straight cutter without irregularities. In addition, in the method of manufacturing a veneer panel, the surface material 103 is adhered to cover the filler 60 on the panel 200 having finished the panel leveling process. (S6) The surface material 103 may include a plurality of veneers. The seam line 103a between the veneers is aligned so as to be located on the intaglio pattern 51.

Subsequently, in the method of manufacturing the veneer panel, the base plate 104 to which the surface material 103 is attached is introduced into the level scraper to scrape the surface material 103 and the part of the filler 60 in the intaglio pattern 51. The scraping depth of the filler 60 should be such that the filler 60 is exposed in the intaglio pattern 51 and the protrusion 52 is not exposed. In the level scraping process, the seam line 103 between the veneers is removed by the scraper 11. Therefore, the present invention does not require a separate process of cutting the seam lines between the veneers of wet plastering or weaving into 4 '× 8' of dry plastering.

When the depth of the intaglio pattern 51 is deep and is a curved and wavefront pattern, the intaglio pattern 51 as shown in FIGS. 10 and 11 may be formed by using a NC (Numerically Controlled Lathe) router. Since the pattern of the filler 60 is the same as the intaglio pattern 51, it may provide various visual effects according to the shape of the intaglio pattern 51.

Edge bands of veneer panels with a complex ridge pattern can be glued with edge bands to prevent moisture penetration of the panels to prevent swelling, deformation and breakage due to moisture absorption of the panel material and to improve aesthetics. have. The edge bands are made of veneer, rolled, veneer, PVC (polyvinyl chloride), PET (Polyethylene terephthalate), etc., and the thickness of the veneer panel is bonded to the edge of the veneer panel. After adhesion of the edge bands, trimming the edges of the edge bands with trimmers allows the edges of the veneer panel to be curved without exposing the base plate 104.
