Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus suitable for continuously producing decorative building panels.

More specifically, a metal thin plate cut to a fixed length, such as 8 shaku, 10 shaku, or 12 shaku, is formed into a predetermined cross-sectional shape, and an uneven pattern is formed on the decorative surface, and sand is applied to the decorative surface. Apply adhesive paint, remove the paint on the convex pattern surface, then distribute sand on this decorative surface in a dense or coarse density, remove excess sand, and remove the paint on the surface of the convex pattern. This relates to a manufacturing device that oversprays a decorative surface and dries it. Metal thin sheets are often used as exterior materials for commonly used architectural panels.

However, thin metal sheets had the disadvantage of being smooth and cold, which is characteristic of metal sheets, and lacking in three-dimensionality. Furthermore, although architectural panels are required to be highly fashionable, they have some drawbacks. In order to eliminate such defects, the present invention forms irregularities in a random pattern on the thin metal plate itself, fills only the concave surfaces with sand, and forms only a coating film on the convex surfaces, thereby creating a three-dimensional makeup. A manufacturing device for continuously producing building panels is provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a decorative construction spring manufacturing apparatus according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic configuration diagram showing an embodiment of the apparatus according to the present invention, in which 1 is a forming means, and FIG. This is a device that molds the material into the shape shown in the figure. In the thin metal plate A, 2 is a concave surface, and 3 is a convex surface, which is formed with an arbitrary pattern such as a random pattern or a uniform pattern with arbitrary size and depth, so-called uneven pattern surface. Reference numeral 4 denotes a means for applying the paint for sand adhesion, and for example, a spraying device, a coating machine such as a flowco 5 series, a roll coater, etc. is used.

Reference numeral 5 denotes a means for removing (wiping off) the paint present on the convex surface 3 of the concave-convex patterned surface in an uncured state, and has a structure shown in FIG. 4, for example.

That is, conveyance rollers R,, R2...R
n and wiping rollers R,',R. ' ・・・・・・・・・
... Rn'' are arranged in series in multiple stages as shown in the figure. Also, the wiping rollers R1'' to Rn'' are provided with a cleaning agent to remove the paint adhering to the roller surface. Applying rollers Rl, r2...Rn are brought into contact with each other.One outer surface of the rollers r1...m must pass through the cleaning agent W1, for example, a solvent.Also, the roller R1''
・・・・・・The surface of Rn is then scraped with a scraping tool, for example, a doctor knife D, and a roller R1″... ・・・Rn
The cleaning agent W and the paint adhering to the roller surface are removed from the wiping roller R1'' as shown in the figure.
R2''... Consists of a structure that prevents the rollers from being conveyed outside the limited area of Rn.In addition, rollers R1 and R1'', R2 and R2''
......Rn and Rn'' are set to the same circumferential speed.
This is because the thin metal plate A is conveyed between the rollers at a predetermined speed without so-called deviation or slip, and when they come into contact, the rubber etc. provided on the surfaces of the rollers R1'', R2''...Rn'' The purpose is to wipe off the paint through the elastic body and phase surface structure.6 is a sand scattering means that scatters sand 7 over the entire uneven patterned surface of the thin metal plate.
A sand spreading device according to No. 72568 is used.

The sand 7 may be colored silica sand, rock powder, glass beads, quartz powder, perlite grains, whitebait, artificial aggregate, plastic powder, etc., and its size may be arbitrary. 8 is a means for removing sand, which is a means for removing excess sand from among the sand scattered on the uneven pattern surface, that is, sand that is not bonded by the sand adhesive paint, such as a fan, or a means for removing sand as shown in FIG. A blower device 9 as shown is used.

It is preferable that this device applies a substantially uniform air flow rate and air pressure to the uneven patterned surface. Moreover, thin metal plate A! They are installed in the same direction or opposite to the direction of travel, and so as to face each other at a certain inclination angle θ. This is because the removed sand 7 does not remain on the uneven patterned surface and needs to be blown out of the thin metal plate A from almost both sides thereof. 10 is a means for applying the decorative paint, such as a flow coater, a roll coater,
A coating method such as spraying is used to strengthen the adhesion of sand to the uneven patterned surface and to strengthen the color, gloss, or coating of the uneven patterned surface.

This kind of paint may be the same as the above-mentioned sand adhesive 4 paint, and for example, the main raw materials are thermosetting acrylic resin, polyester resin, alkyd resin, epoxy resin, acrylic polyurethane resin, yellowing polyurethane resin, melamine resin, etc. It is a paint that Reference numeral 11 denotes a drying means, such as a baking furnace using one or a combination of electricity, gas, ultraviolet rays, and far infrared rays.

Reference numeral 12 denotes a conveying means, which is a device for moving the thin metal plate A at a constant speed while keeping it horizontal; for example, it is composed of a belt or a roller alone or in combination, and has a structure that allows the speed to match the above-mentioned conveying speed. It is. Next, it is assumed that nine architectural panels having a sand decorative surface (decorative architectural panels) are manufactured using the apparatus according to the present invention.

FIG. 6 is a vertical cross-sectional view showing a part of a building panel manufactured using the apparatus according to the present invention, and FIG. 7 is an explanatory view showing a part of the cut part in an enlarged manner. Therefore, as the thin metal plate A, a colored iron plate (clay color) having a plate thickness of 0.27 Trrm and an emboss depth of 0.7 mm and having a pattern as shown in FIG. 72 formed thereon is prepared. Next, a sand adhesive paint (cream color) is applied to this uneven patterned surface to form a coating film P. This state is shown enlarged in FIG. 7a. In this case, the main component was an alkyd resin, the viscosity of which was set to about 800 to 1000 centipoise, and this was coated to a thickness of about 10 microns (wet) using a flow coater.
Next, the paint P existing on the convex surface while the paint film P is still uncured is removed by a wiping device (
For example, as shown in FIG. 4). Next, sand 7 is applied to this uneven patterned surface through the sand scattering means 6 as shown in FIG. 7c.
Scatter as shown in enlarged view. In this case, the sand adhesive paint is still in an uncured state. Next, the top 3 of the convex surface 3
Excess sand on the convex surface 3a and the concave surface 2 is removed from the sand 7 existing on the convex surface 3a and the concave surface 2 through the sand removing means 8, as shown in an enlarged view in FIG. 7d. This is to create a mixture of a flat surface and a highly undulating surface made of tightly packed fine sand, or a concave surface formed outside this surface. The purpose of this is to obtain a cosmetic surface that exhibits a novel appearance that is a harmonious combination of natural and artificial appearance. Moreover, at this time, it is preferable that the tops of the sand distributed on the so-called concave surface do not protrude beyond the top 3a of the convex surface 3 described above. This is effective in producing an image with unique color tone, brightness, etc. due to the effect of surface reflection by the top plane and diffuse reflection by the uneven surface of the concave surface. Next, a decorative paint (glossy, cream color) is applied to the convex surface 3 and the concave surface 2 on which sand is distributed, using means 10 (spray gun) for applying it, as shown in an enlarged view in FIG. Apply approximately 30 microns (wet) to the surface.

Although a glossy paint was used, when applied to a sandy surface, the color appearance is almost the same as that of a matte surface. Moreover, the coating film P'' made of this decorative paint protects the sand from falling off, the base from discoloration, etc. Next, the thin metal plate A is fed to the drying means 11.

In this case, the preheating zone below 100℃ is 6 to 9 minutes, 20 minutes
A gas combustion type device was used, which had a 1-minute baking zone at 0 to 250°C. Further, as a conveying means, a belt was set at a speed of approximately 607 T1, Imin, and the thin metal plate A was conveyed to the baking furnace via this belt. In the case of the apparatus according to the first invention, the drying means is optional. What has been described above is only one embodiment of the manufacturing apparatus according to the present invention, and for example, a pre-drying means may be used in the portion shown by the dashed line in FIG.

Further, as shown in FIG. 8, as an example of the wiping means, a roller may be formed so that the gap thereof is substantially sloped.
Furthermore, by changing the relationship between the sand spreading amount of the sand spreading means 6 and the speed of the conveying means 11, the ground color a of the thin metal plate A is exposed due to agglomeration of sand as shown in FIG. 9. is also possible.

Further, when the thin metal sheet A is supplied to the forming machine in the form of a coil, it is necessary to install a running cutting means at the position indicated by the half line. As described above, according to the decorative construction panel manufacturing apparatus according to the present invention, a construction panel that exhibits a novel appearance in which a mirror-like convex surface and a raised surface formed from small grains such as sand are mixed is decoratively produced. It has the characteristic of being able to be manufactured in large quantities with uniform quality at high speed and continuously without damaging the surface.
