Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves forming an arbitrary uneven pattern by embossing on a thin metal plate having a decorative coating film or a decorative film made of film, and applying a three-dimensional effect promoter to this uneven pattern. This invention relates to a three-dimensional effect enhancement device that can easily add a visual three-dimensional effect by color to a mechanical uneven pattern and continuously produce a decorative thin metal plate having a deeper uneven pattern surface. .

In general, thin metal sheets, especially self-painted steel sheets, funoso resin-painted steel sheets, and PVC steel sheets, are being used for a wide variety of purposes. This is because this type of steel sheet has excellent workability, quality, and appearance, and is also durable.

Recently, the demand has shifted to steel plates that have a three-dimensional effect, two-tone color, etc. added to the flat surface of the steel plate to enhance fashionability. As a steel plate corresponding to this, for example, a steel plate on which an irregular pattern is formed by embossing is commercially available. However, when salt spray tests (J 1s-Z-2371) were conducted on these steel plates, the bending HIN rusted and rusted after 500 to 1000 hours.
Peeling of the coating was observed. In addition, the surface of this type of steel plate is
When observed with double magnification, the curved parts of the concave and convex parts show that the coating is 1
Some parts of the pattern were peeled off, wrinkled, scratched, scratched, thinned, and cracked. This is because the embossing line is not suitable. Furthermore, simply adding two-tone colors to the decorative surfaces of cars lacks the ability to visually enhance the sense of fashion.

In order to eliminate such defects, the present invention softens the decorative film during embossing to exhibit ductility, thereby eliminating peeling, wrinkles, scratches, and cracks of the decorative film, and making it easy to reduce residual strain during embossing. The sloped surface (side surface) has at least a convex pattern and a beautiful decorative surface.
- By applying a three-dimensional effect enhancer based on one's ability, mechanical three-dimensional effect is strengthened, and ffji simply adds a visual three-dimensional effect, and colors etc. function more shadingly to create an unprecedented three-dimensional effect. This paper proposes a device for enhancing the three-dimensional effect of a makeup surface, which is designed to create a sense of beauty.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A device for enhancing the three-dimensional effect of a decorative surface (hereinafter simply referred to as an enhancement device) 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 example of the above device,
The soil is fed to a thin metal plate feeding section (hereinafter simply referred to as the feeding section), which consists of an uncoiler 2 and a pinch roller 3, and is made of a flat metal thin plate wound into a coil (decorative coating + 1A, decorative coating such as decorative film). This is for attaching A) and feeding the loop part 4 easily when it is full. Loop part 4

In addition, the heater section consists of a pinch roller 6 that also serves as a guide l', and a heater 7, and the second pinch roller 6 holds the 21st wheel A with the upper and lower rollers 6a and 6b only at the line start, and then This is to feed 2l Δ to the heater 7 as the insect chil'l: I-ra. In addition, the heater 7 is a decorative coating on the coil, which is essentially the coil A itself.
The decorative film is heated to 0 to 60°C to soften it, and the decorative film will peel off or crack from the steel plate during embossing.
This prevents scratches and cracks from forming. The heating method is one of a hot wind type, a thermal power type, and a hot wire type. Numeral 8 is a pinch roller which feeds the coil A at a predetermined speed to the embossing roll 9 and also functions as a brake against the movement of the coil Δ during the embossing process. The Enphos Roll 9 has a pattern consisting of male and female uneven parts formed on its outer circumferential surface.

Reference numeral 12 denotes a three-dimensional effect-enhancing agent applicator (hereinafter simply referred to as coating machine 4) to coat the entire surface of the concave pattern B and convex pattern C as shown in FIG. 2 (11) and (b). It is applied only from one amount. Zunawara~Three-dimensional effect enhancing agent base Figure 4 (al~As shown in (C), the three-dimensional effect enhancing agent is applied to the concave pattern surface B, the top surface E of the convex pattern C, and the side surface 1 of the convex pattern C. At least one type of film, dot, or line is formed only on the surface that collides with the coating machine 12, and the angle θ (0 to 90°
), the shape and depth of the uneven pattern, and the moving speed of coil A' to adjust the shading that functions as a shadow according to the purpose.
It is formed in such a way as to enhance the three-dimensional effect and to induce a sensation of ``l'' (the uneven pattern 13, C appears to be reversed) in the viewing direction. In addition, the insertion W and C
14 pieces are used: a sprayer, a roller, a roller, a roller, and a coater. In addition, at θ-0° and 90°, the vL sensation enhancer 1) is present in the range where there is a so-called convex pattern side curve on the back side facing the forward horn. This is to take advantage of the fact that it no longer occurs. 13 is a wiping machine used to wipe off the three-dimensional effect enhancer on the J-RI surface with a convex pattern, thereby allowing the makeup coating to leak out.

In addition, the wiping machine 134 is used to gradually wipe the α-sensation enhancer by arranging multiple stages (only one stage is shown for 1 ml) in parallel. In addition, the wiping area 13 is the wiping 1: J-ra l 3 a and the hacking roller l.

It consists of a foot roller 13d that is supplied to a.

Reference numeral 14 is used to dry the convex patterned nail surface of the concave and convex patterned surface in a drying oven, and also to dry or bake the three-dimensional effect promoter.

Next, the operation of the reinforcing device h° according to the present invention will be explained. First, the flat coil A mounted on the feeding section is fed to the loop section 4 via the pinch roller 3. In addition,
At this time, even if the coil A is pulled by the pinch roller 3, the uncoiler 2 is equipped with a brake device (not shown), so the coil A is fed to the loop section 4 under a certain allowable tension. It is something. Then, the coil A from the loop part 4 is sent to the heater 7 via the pinch roller 6 which also serves as the chi 1'' and is heated to approximately 30 to 60°C, softens the decorative film, and then passes through the pinch roller 8. The pinch roller 6, which also serves as a guide, binds the coil A to the pinch roller 8 until it stabilizes.
aN, and after that it works simply as a guide roller. The coil A sent out from the pinch roller 8 is sent to the embossing roll 9, and the coil A is sent out from the pinch roller 8.
For example, a cone pattern consisting of a concave pattern B and a convex pattern C as shown in Fig. 2(a) and (bl) is continuously formed.At this time, tension is applied to the coil A. Embossing is performed in a state where the
The coil 8' roller sent out from the embossing roll 9 corrects the residual strain generated during embossing in the tensioned state between the embossing roll 9 and the tensioning pinch row 911, and then the coating machine 4J. The force relationship between the pinch roller 8 and the tensioning pinch roller 11 with respect to the coil A is based on the rotation of the embossing 1 coil 9.
la, the rotation of the pinch roller 11 is slow and the rotation of the tensioning pinch roller 11 is set to a fast rotation to destroy the embossing and uneven patterns B and C with the coil A being stretched. Instead, the coil A' is flattened as a whole, and residual strain is removed. As a result, the coil A' no longer curves in the above-mentioned area, moves torsionally, or fluctuates due to the embossing roll 9], and the embossed pattern becomes unclear. Tari, 2 YunilllX1
There is no need to worry about it. In addition, in the rehera lO, since the tension is applied to the amount of force, the coil A'
As described above, it is possible to easily flatten the surface and also to release residual strain without difficulty. Of course, the tension within the above region G is within the range of force that does not change the embossed pattern.

In addition, D sent out from the tensioning pinch roller if is placed so as to face the entire surface of the uneven pattern surface at an angle of θ=45° with a spray gun in the direction of movement of the coil, as shown in FIG. 4(a). (It is applied and adhered as shown in C1. Of course, at this time, in each part of the concave pattern B and convex pattern C, Alternatively, the distribution is such that the density gradually changes.

The 21-irvane having such an uneven decorative surface is then sent to a wiping machine 13, which wipes off the three-dimensional effect enhancer I applied to the top surface of the raised pattern C, and then applies the coil A to the top surface of the raised pattern C. ′

Comparative Example Coil A as described above was embossed using the conventional method of 1-, and then embossed with a spray gun from directly above the so-called uneven pattern surface. A test piece was prepared by applying 4iL of paint and drying it.The appearance of the unevenness 4Q is shown in FIG.

Further, the results of a salt spray test (j500 hours) of the coils formed in the example (coil A when the decorative coating was heated to 50° C.) and the comparative example were as shown in the table below.

What has been described above is not only one embodiment of the reinforcing device according to the present invention, but also includes keeping the temperature from the heater 7 to the tensioning pinch roller 11 within a temperature range of about 30 to 60°C, and the proportion of 41% of the uneven patterns B and C. Depending on the situation, it is possible to increase the number of rollers on the rehera, to arrange the uneven patterns so that they spread out from the center, or to distribute the uneven patterns only over a certain width. Furthermore, if the coil is a cut plate, it can be manufactured in the same way from the heater section in a subsequent process, and a curtain flow coater can also be used. In addition, the convex pattern 1 of the concave and convex pattern
1' may have a mirror surface, a matte surface, or a 1-slanted surface U11 as shown in FIG. In addition, a magnifying glass or a video camera may be placed at the position indicated by the dashed line in FIG. 1 to monitor the cosmetic coating film formed by the enphos process. Further, as shown in ta+ in Fig. δ, the applicator 12 is applied from one direction or two directions of the side surface in the traveling direction of the coil A' at a certain angle, for example, from 0 to 90'; As shown in the figure, when forming a double width, apply the three-dimensional effect enhancer [1] at an arbitrary angle from both sides in the direction of movement.
It is also possible to add competence to the dispensing of the inhibitor IJ. In addition, for double width, there is a masking part + in the center of the coil.
It is necessary to prevent the three-dimensional effect enhancers D from colliding with each other at the central part where the coil is inserted.

- As mentioned above, the reinforcing device according to the present invention has (O
