Description

Manufacturing apparatus and method of multicolored multicolored leather

The present invention relates to an apparatus for producing multicolored multicolored or multicolored multicolored leather and a method thereof. More specifically, the production apparatus is provided with a plurality of workbench on the conveyor, and the injection apparatus and the drying chamber alternately along the movement path of the conveyor alternately; The present invention relates to a method of forming one or more colors and patterns by contacting the leather with one or more pattern-forming plates and then coating the composition with a method such as spraying.

In the conventional case, when painting the leather by spraying, only a single color was possible. Two colors of leather can be embossed to rub the concave and convex parts by hand, pull-up using roller coating, polishing, oil wax, etc. The two colors are expressed by the antique effect and the crack using the binder crack.

There is an amorphous multicolor, but this is a pattern that changes the color with a hand spray gun, which has a problem that is not reproducible.

The thermal transfer method manufactures and pastes a film having a pattern color, which lowers the breathability which is a characteristic of leather.

In the screen printing method, since the thickness of the leather is not constant and there is a variation in each part, even if a constant pressure is given by a squeegee, the thin part is not clear and the thick part is more clear. Even more so.

In the conventional case, a multicolored pattern or a multicolored multicolored pattern could not be formed in the coating process of leather. This is not only a single color because the coating color layer is uniformly formed on the entire surface on the leather in which one color is formed. When only the part was coated with color, it became multicolored, but it was not reproducible.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus and method for solving the problems of the prior art and for forming a multicolored pattern or multicolored pattern on leather.

In order to achieve the above object, a plurality of pattern forming plates are formed to form various patterns of various colors, and the pattern forming plates are placed on top of the leather, followed by spraying a composition of a desired color with an injector or the like and then drying the pattern. The present invention provides a multicolored pattern or a multicolored multicolored apparatus and method for forming the same pattern having a plurality of colors or various patterns having a plurality of colors.

According to the present invention, a pattern having a plurality of colors or various patterns having a plurality of colors may be formed on the leather by coating by spraying various pattern forming plates and compositions representing various colors. In addition, the respective patterns may be formed differently in gloss, and in particular, there may be reproducibility, so that standardization of mass production may be possible. Therefore, the creation of new fashion and design has the effect of expanding demand, increasing exports, and enabling mass production.

In addition, one moving device 14 may be installed or may be installed for each injection chamber. If one is to be installed, its working range should be wide.

The composition used in the manufacture of the leather sprayed through the injector 6 is any one selected from compositions expressing colors such as aqueous dye pigments, oil dye pigments, gold powder, silver powder, Pearl (Pearl) and the like to fix the composition It comprises a binder and a lacquer which protects the film of a product.

The method of forming a multicolored pattern or multicolored multicolored pattern on leather using the apparatus as described above will be described in detail.

First, the leather in the present invention is a variety of leather, such as a silver (Grain) leather with a pore layer, silver leather buffing the pores, split leather with a six-layer layer, dyeing split leather, or undyed split leather Can be used.

The first step is a preparation step, in which the leather is unfolded in the preparation chamber 9 and fixed inside the fixing frame 2 of the worktable 3 installed on the conveyor 1 using the fixture 12.

The leather is spread out inside the fixing frame 2 of the work table 3 provided on the conveyor 1, and fixed to the rubber pad 11 using a fixing tool. In the case where the work bench 3 is made of a rubber board or a wooden board, the rubber pad 11 is unnecessary and may be fixed directly to the work bench 3 using a fixing tool.

This is done in the preparation room 9. In the preparatory chamber 9, the leather is spread widely and put into the inside of the fixing frame 2, and spread flatly on the bottom of the work table 3, and then using a fixture 12 such as a tacker, a stapler, and an adhesive paste. The leather is fixed to the worktable (3).

Except for the rubber workbench 3 and the wooden workbench 3, a plurality of rubber pads 11 are flatly provided at the bottom edge of the worktable 3, and a rubber pad 11 is provided in the center. The rubber pad 11 on the edge side uses a tacker, a stapler, an adhesive paste, and does not affect much of the product because it is an end portion. The rubber pad 11 installed in the center is preferably fixed using an adhesive glue so as not to damage the leather.

It is also possible to base coat the leather before the first step. Base coating is a pretreatment process in which the monochromatic leather, which has been dyed and dried, is pretreated by application and then coated in a painting process. This is a single color coating on the surface of the leather with a composition that expresses and adheres to the color for the covering of the damaged part so that the color of the leather is severely different from the desired color or to improve the quality of the product.

The second step is the first painting step, the conveyor 1 is advanced to move the leather to the spray chamber, the pattern forming plate 4 is placed on the leather using the moving device 14, the composition is sprayed ( 6) by spraying to form a pattern of a specific color through the perforations of the pattern forming plate (4).

When the leather is fixed in the preparation step, the conveyor 1 is advanced to move to the spray chamber 7a and stop, and the pattern forming plate 4 is placed on the upper portion using the moving device 14 so as to contact the leather. One pattern or various patterns are perforated on the pattern forming plate 4, and the leather is exposed only to the perforated part.

The composition to be sprayed includes an aqueous dye pigment, an oily dye pigment, an oily gold powder or silver powder or pearl, and the like, water or butyl acetate used as a solvent and a solvent, a binder fixing the color to the leather and protecting the coating layer, and an auxiliary agent thereof. (A wax filler, a matting agent, a dispersant, a leveler, a touch agent, a thickener, etc.), a penetrant, an oil-based lacquer and its auxiliary agent, a touch agent, a silicone, and the like.

Since one pattern forming plate 4 is perforated only part of the pattern to display the same color, the pattern forming plate 4 is required as many as the number of colors to be displayed, the base of the leather or base untreated leather If the color is the same as any of the desired colors, the number of one can be reduced.

And the injector 6 which injects the composition for expression of color and fixation is provided in the injection chamber 7a. Therefore, as shown in FIG. 3, when the composition is sprayed from the injector 6, only the leather part exposed to the perforation part of the pattern forming plate 4 is formed in color and pattern as shown in FIG. 4 (a).

In the spraying, the gloss may be changed by adding or subtracting the content of the matting agent included in the composition. Therefore, by doing this, it is possible to make the gloss different for different patterns, thereby producing various effects.

The third step is a first drying step, in which the conveyor 1 is advanced to move the leather to a drying chamber to dry the leather. Of course, when the composition is buried in the pattern forming plate 4 and the composition flows down or there is a concern that the leather may be contaminated, the pattern forming plate 4 may be moved and dried together with the leather. Alternatively, the pattern forming plate 4 may be unconditionally dried together with the leather.

The conveyor 1 is operated forward to move the leather which has completed the second step to the drying chamber 8a to be dried. It is preferable to dry by hot air in the said drying chamber 8a.

The reason why the pattern forming plate 4 is dried is to prevent the next work from being contaminated by the composition buried in the pattern forming plate 4 and to perform defects.

The fourth step is a step added only when the pattern forming plate 4 is dried, and returns the dried pattern forming plate 4 to the spray chamber where the pattern forming plate 4 should be present. Therefore, the conveyor 1 is stopped and stopped in the spray chamber, the pattern forming plate 4 is lifted by the moving device 14, and the conveyor 1 is moved forward to move the leather to the next spray chamber to stop. .

When the drying is completed in the previous step, the injector 6 is stopped and the conveyor 1 is driven back to stop the pattern forming plate 4 in the injection chamber 7a. In the stopped state, the moving device 14 is operated in the spray chamber 7a to lift the used pattern forming plate 4 upward. Then, the conveyor 1 is advanced again, passes through the drying chamber 8a, moves to the next spray chamber 7b, and stops.

After advancing, new leather is moved into the spray chamber 7a, and the patterned plate 4 dried after being used at the top thereof is placed using the moving device 14.

At this stage, the pattern plate 4 can also be returned in place without reversing, which can be done using the moving device 14. That is, the pattern forming plate 4 in the drying chamber may be picked up by the moving device 14 and then moved to the injecting chamber in place. In this case, the conveyor 1 may not be reversed.

The fifth step is an additional coating step, in which a different pattern forming plate 4 is placed on the upper part of the leather using the moving device 14 in the spray chamber, and then sprayed with a composition for expressing and fixing other colors used in leather manufacturing. 6) spraying step.

Using the pattern forming plate 4 in the leather moved to the spray chamber (7b) in the previous step is to spray the composition for the expression and fixing of the pattern of the different colors or other colors of different colors to the injector (6).

Accordingly, the other pattern forming plate 4 is formed with a perforation to form a pattern different from that of FIG. 4 (a) as shown in FIG. 4 (b). Therefore, after the fifth step, the multicolored pattern or the multicolored multicolored pattern is formed on the leather as shown in FIG. 5. Depending on the pattern, the pattern forming plate 4 is made to overlap a little, so that the overlapped portions naturally express different colors.

The sixth step is an additional drying step in which the conveyor 1 is advanced to move the leather to the next drying chamber to dry the leather. Of course, in this case, the pattern forming plate 4 may be dried together. In this case, the conveyor 1 may be moved to move the leather to the drying chamber 8b to stop, and then the pattern forming plate 4 and the leather may be dried. In the case of drying only the leather, the pattern forming plate 4 is lifted by the moving device 14, and only the leather is moved to the drying chamber 8b.

The seventh step is a repetition step, in which steps 5 and 6 are repeated to complete the desired number and colors of patterns. The number of repetitions is determined according to the number of desired patterns and the number of colors, and the repetition process of spraying and drying is performed an appropriate number of times according to the color used, thereby producing a multicolored pattern or a multicolored multicolored leather. Therefore, the seventh step may be performed without going through the next step.

The eighth step is a coating step, in which a composition for protecting the film used in leather production is coated on the multicolored pattern or multicolored multicolored leather formed in the previous step.

The ninth step is a finishing step, in which smoothness and soft embossing are given.

Looking at the embodiment of manufacturing a variety of leather products using the above method as follows.
