CONSTITUTION:A metallic thin plate is fed to a printing part 4 from a metallic thin plate feed-out part 1, and an optional pattern is printed on a decorated surface. Subsequently, it is fed to a heater part 11 and heated to about 30-60 deg.C, and a base coat and a top coat are softened. Next, it is made to pass through an embossing roll 12 and decorated with an optional pattern, and thereafter, made to pass through a leveler 13, and a residual distortion of the time of embossment is straightened. By a tension pinch roller 14 provided in the rear of the leveler 13, the metallic thin plate is made to pass through the embossing roll 12 and the leveler 13 in a state that it is drawn. Subsequently, it is fed to a cutting machine 15a and a recoiler 15b, etc. According to this solid-converting device, a decorated surface which causes no deterioration of a printing pattern and is excellent in resistance to weather, scratch, etc. can be formed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a three-dimensional effect by printing an arbitrary pattern in an arbitrary color on a thin metal plate and embossing an arbitrary uneven pattern on the printed thin metal plate. The present invention relates to a three-dimensional decorative surface device that can continuously form surfaces.

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 copper plate, galvanized steel plate, galvanized 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. An example of this is enforcing a steel plate or printing an arbitrary pattern on it. Furthermore, there are products in which the coil is printed and embossed, but in this case, the printed film was laminated onto the coil and then embossed.

This type of product has the disadvantage that the film peels off from the coil during embossing, and because the film is attached to the decorative surface, the embossed pattern does not stand 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.

In order to eliminate these drawbacks, the present invention prints on the coil itself and then embosses it, and easily corrects residual distortion during embossing to create a beautiful decorative surface with a three-dimensional effect. This paper proposes a three-dimensional decorative surface device that can efficiently manufacture decorative surfaces.

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 transported through a metal thin pile part (hereinafter simply referred to as the sending part), and as shown in FIG. 2, an uncoiler 2 and a pinch roller 3, or a Consisting of only the uncoiler 2 or one of a metal thin plate stacking table, a lifter, etc., a flat metal thin plate wound in a coil shape or a fixed length metal thin plate (hereinafter collectively referred to as a coil) A is attached, Or it is for stacking and 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).

It consists of a fountain roll 9e and a shimeshi roll 9f. Note that the dryer 6a and oven 8a can also be arranged at the positions indicated by dotted lines in FIG. 11
The coil A is heated to approximately 30 to 60 degrees Celsius in the heater section to soften the base coat and top coat, so that both coats may peel off from the coil A itself during embossing.
This prevents cracking or cracking of the top coat. The heating method is one of a hot air method, an open flame method, and a hot wire method. Reference numeral 12 denotes an embossing roll having the configuration 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 FIG. 6 fat and fill. That is, the embossing roll 12 has a pattern consisting of male and female uneven parts formed on its outer peripheral surface, and an arbitrary pattern is applied to the coil A by meshing upper and lower rolls 12a and 12b. The gap is determined by the height of the uneven pattern and the thickness of the coil A.

A pinch roller 17 can also be provided in between. Furthermore, it is also possible to match the printed pattern and the embossed uneven pattern, or to make them different.

As described 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 there is a top coat on top of the printed pattern, there is no deterioration of the printed pattern. ■Since the embossing process can be performed under constant tension, the embossed pattern does not shift during processing, and a beautiful uneven pattern can be formed. ■Since the base coat and top coat are softened during embossing, each coat will not be cracked, scratched, cracked, or peeled from the coil itself, making it weather resistant and scratch resistant. , 0 A coil with poor chemical resistance can be formed. ■Residual distortion caused by distortion formed by embossing can be easily and sufficiently removed by straightening 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 enhosing. ■Because it is simply printed and processed, it can be produced at low cost. It has the following characteristics.
