Description

Detailed Description of the Invention The present invention prints an arbitrary pattern on a thin metal plate in an arbitrary color, embosses an arbitrary uneven pattern on the printed thin metal plate, and functions as a directional shadow on the uneven pattern. Apply a three-dimensional effect enhancer to areas other than the top surface of the convex pattern, print,
This invention relates to a three-dimensional decorative surface making device capable of producing a beautiful decorative surface with a deep three-dimensional effect and excellent weather resistance through the synergistic effect of embossing and a three-dimensional effect promoter.

A thin metal plate (hereinafter simply referred to as a coil) is, for example, a steel plate (
It consists of one type of surface-treated steel plate, galvanized steel plate, galvalume steel plate, stainless steel plate), aluminum plate, and copper plate, and since these themselves lack design and three-dimensionality, attempts have been made to add various treatments to them. Examples include embossing or printing arbitrary patterns on steel plates. Furthermore, there are products in which the coil is printed and embossed, but in this case, printed lime was laminated onto the coil and then embossed. This type of component has the disadvantage that the film peels off from the coil during embossing, and because the film is attached to a decorative surface, the embossed pattern stands out clearly and lacks a three-dimensional effect. In addition, the film may be destroyed by embossing, lacks weather resistance and corrosion resistance, and there is a limit to the size of the uneven pattern created by embossing, especially small patterns. Furthermore, this type of coil lacks the three-dimensional effect due to shading, so there is no directionality in the three-dimensional effect, and the force of the flat appearance cannot be avoided.

In order to eliminate these drawbacks, the present invention prints on the coil itself and then emboss it, easily correcting the residual distortion during embossing, and in addition, the uneven pattern surface has a directional pattern. To propose a device for creating a three-dimensional cosmetic surface, which can apply a three-dimensional effect promoter that forms a shadow-like three-dimensional effect and produce a cosmetic surface that creates a deep and illusory three-dimensional effect at a high fju rate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a three-dimensional decoration device (hereinafter simply referred to as a three-dimensional device) for a decorative surface according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing an example of the structure of the above-mentioned device, and the soil is fed to the thin metal plate sending section (hereinafter simply referred to as the sending section), and as shown in FIG. It consists of one of a chisel, a metal thin plate lamination stand, a lifter, etc., and is equipped with a flat metal thin plate wound into a coil, or a fixed length metal thin plate (hereinafter collectively referred to as a coil) A, or laminated. This is for feeding coil A to the printing section ↓. The printing section ↓ prints an arbitrary pattern and color directly on the decorative surface of the coil A (in addition to the above, it also includes primer steel plates and pretreated steel plates). To explain further, the printing section ↓ prints an arbitrary pattern on the decorative surface by any one of gravure printing, offset printing, screen printing, letterpress printing, and planographic printing. Note that printing is performed on any decorative surface. For example, the third

Note that the dryers 1 and 6a and the oven 8a can also be arranged at the positions indicated by dotted lines in FIG. 11 heats the coil A to about 30 to 60 degrees Celsius in the heater section to soften the base coat and top coat, and prevents the above coats from peeling off from the coil A itself or cracking the top coat during embossing. This is to prevent it from occurring. The heating method is one of a hot air method, an open flame method, and a hot wire method. 12 is an embossing roll having a structure as shown in FIG. 5, and is used to form an arbitrary uneven pattern on the coil A, for example, an uneven pattern as shown in FIGS. 6 (al, (bl)).

That is, the embossing roll 12 has the same diameter or almost the same diameter as the printing roll, and has a pattern consisting of male and female uneven parts formed on its outer peripheral surface. A pattern is applied to the top,
The gap between the lower rolls 12a and 12b is determined by the height of the uneven pattern and the thickness of the coil A. - The shell is for correcting the residual strain existing in the coil A' embossed with the leveler, and the upper roller 13a 113a

Next, the operation of the three-dimensionalization apparatus according to the present invention will be explained. First, the wound coil A is attached to the uncoiler 2 on the delivery section. Next, the coil A is fed to the printing section ↓ via the pinch roller 3.

In the printing department, the decorative surface of the coil A is washed, the cleaning liquid is dried with a dryer 6, a base coat is applied to the decorative surface with a coater 7, and the coated surface is sent to an oven 8. Oven 8
On the decorative surface of the coil A sent from the coil A, the printer 9 prints a two-color pattern as shown in Figure 6+al and (bl), with gray on the so-called concave pattern B and white on the top surface or peak of the convex pattern C. Next, a top coat made of transparent paint is applied to this decorative surface from a top coat applicator 10, and this is sent to the heater section 11. In the heater section 11, the coil A is
The base coat and top coat are softened by heating to 0 to 60°C and fed to the embossing machine 12. The embossing roll 12 has an uneven pattern as shown in Fig. 6+al and (bl) for the coil A, and its enlarged cross section is shown in Fig. 8(α)-(
A pattern as shown in el is continuously formed.

At this time, the embossing process is performed while tension is applied to the coil A. Then, the coil sent out from the embossing roll 12 is passed through the register 13.

2 and the tensioned pinch roller 14, and then fed to the coating machine 15.

In addition, when embossing is performed on the coil A, the embossing is performed in a state where the space between the embossing roll 12 and the tensioning pinch roller 14 is tensioned.

In addition, in coating machine 15, a promoter agent having at least one of density, hue, and saturation different from that of the printed pattern is applied to the entire surface of the uneven pattern surface at θ1=45° for the coiled pattern. It is applied thickly to the side surface of the convex pattern C that collides with the promoter, except for the so-called surface located on the back side in the direction in which the promoter is applied. The coil A', which has become such a decorative surface, is then wiped off with a wiping machine 16 to remove the promoter present on at least the top surface of the convex pattern C, exposing the printed pattern on the top surface of the convex pattern C, and then placed in a dryer. 17, and the promoter is dried or baked. Next, this coil λ is used, for example, in the cutting machine 18.

A pinch roller 21 may be provided between the two, or a device 22 for applying the masking material to the convex pattern C may be arranged between the tensioning pinch roller 14 and the coating machine 15. It is also possible to match the printed pattern and the embossed uneven pattern, or to make them different. Furthermore, the printed pattern and the uneven pattern formed by embossing are almost the same, and the pattern is printed so that the uneven pattern almost matches the shading of the product coated with the promoter paste, and this and the embossing roll 12 are combined as shown in FIG. It is also possible to manufacture them in synchronization using the controller 23 shown.

As mentioned above, according to the three-dimensional device of the present invention, it is possible to directly print on coils that have only been subjected to surface treatment, or on commercially available unpatterned coils, so there is no possibility that the printed pattern will stretch or shrink during embossing. The beautiful pattern remains.

■Since Tosopko-1 is placed on top of the printed pattern, there is no deterioration of the printed pattern. ■Since embossing can be performed under constant tension, the embossed pattern does not sag or disappear during processing, creating a beautiful uneven pattern. ■Since the head coat and top coat are softened during embossing, each coat will not be cranked, scratched, cracked, or peeled from the coil itself, making it weather resistant and scratch resistant. , it is possible to form a coil with excellent chemical resistance. ■Residual distortions caused by distortions formed by embossing can be easily and sufficiently removed by correction under tension, making it possible to form a concave-convex pattern with no distortion and full of three-dimensional effect. ■The lines are arranged in a straight line and the process uses a flow that does not apply excessive force to the coil, allowing for smooth printing and embossing. ■Because it is simply printed and embossed, it can be produced at low cost. ■As the promoter is distributed in a directional manner except on the top surface of the convex pattern, it creates a deep three-dimensional effect. It has the following characteristics.
