Description

Floor decoration material manufacturing apparatus and its manufacturing method {MANUFACTURING APPARATUS OF FLOOR DECORATION SHEET AND METHOD OF MANUFACTURING THE SAME}

The present invention relates to an apparatus for producing floor coverings and a method of manufacturing the same.

Prior art literature for imparting a three-dimensional effect to a vinyl flooring material is disclosed in Republic of Korea Patent Application Publication No. 10-1993-023190 (published Dec. 18, 1993), and the three-dimensional pattern method described therein includes a foaming agent in the printing layer to produce a printed pattern. The technique which expresses a three-dimensional appearance by protruding is disclosed. In the conventional vinyl flooring material applying the above technique, in applying a printing pattern to a printing layer containing a foaming agent, an ink in which a foaming accelerator or a foaming inhibitor is added is used, and the printing layer to which the printing pattern is applied is a foaming oven (Oven). Pass through), it gives a three-dimensional appearance effect while promoting or suppressing only the printing part containing foaming accelerator or foaming inhibitor.

However, the above-mentioned vinyl flooring decorative material has a disadvantage in that it is difficult to use in places where walking is frequent because the surface layer is weakened due to the printing layer of the upper portion of the product made of foam. In addition, since a round embossed pattern is obtained rather than a delicate embossed shape, there is a limit in expressing a delicate three-dimensional appearance with a sense of depth.

On the other hand, as another prior art document there is the Republic of Korea Utility Model Publication No. 20-1995-0009019 (published on April 19, 1994.), the decorative material of the floor described in this document imparts a concave-convex pattern with an embossing roll to the printed layer, After the ink is filled in the uneven embossed pattern, a predetermined printed pattern is printed thereon and an upper transparent layer is formed to impart a three-dimensional appearance effect.

However, such a floor decoration agent does not match the printed pattern and the embossed pattern, and the ink and the printed pattern filled in the embossed pattern is directly stacked, there is a disadvantage in lack of three-dimensional and realism. In addition, the ink is applied to the entire surface of the embossed patterned printing layer to fill only the recessed portion, and the remaining portion of the ink is to be removed.

Meanwhile, in order to express a three-dimensional appearance effect in a piece type floor decoration material, for example, a tile type floor decoration material, which is not a long floor decoration material as a conventional floor decoration material, an embossed pattern corresponding to a specific negative printed pattern is used. In order to provide, three-dimensional impression was provided using the flatness of the metal material by which the uneven | corrugated embossing which matches the printing pattern of a specific site | part is carved. However, this method is limited in that it is possible to produce only a piece-type product by applying flat embossing, and is not applicable to a long vinyl floor decorative material to which a continuous process is applied. Therefore, the piece-type floor decorative material is lowered in productivity, the product price is increased, and the construction is more difficult than the long product when constructing the product, which requires a lot of labor cost and time.

Recently, as an alternative to this, the printing print is transferred to a PVC sol impregnated layer impregnated with glass fiber which is stable to heat and tension, and a print pattern of PET sheet which is stable to heat and pressure. There has been an attempt to solve the problem by employing a layer and to match the position or shape of the printed pattern of the transfer printed layer with the embossed pattern of the emboss layer. However, this method is deteriorated in price competitiveness due to the addition of a glass fiber layer, a PVC impregnated layer, an anti-bending interlayer, and the advantages as a final product are greatly halved.

An object of the present invention is to apply a carrier film having a low thermal expansion and high temperature elongation without adding a glass fiber layer, thereby controlling irregular stretching from transfer printing to embossing, thereby achieving matching of the printed pattern and the embossed pattern.

The conventional floor decorative material manufacturing apparatus is based on the installation of each roll in an inline form along one direction, and when the embossed pattern is applied to the floor decorative material, in particular, the PVC floor decorative material by the embossed roll of the uneven structure, As the moving distance increases and the printed pattern of the printed layer increases due to the heat involved and the tension for the progress of the base sheet on which the printed layer is formed, it is impossible to align the printed pattern and the embossed pattern.

In addition, the floor decoration apparatus according to the prior art it is impossible to drive the emboss roll individually because the emboss roll is driven through the turn emboss. Accordingly, the conventional embossing roll has a problem that it is difficult to control the printed pattern and the embossed roll of the embossed roll to match the unevenness of the printed pattern and the embossed roll body when an error occurs in the printed pattern.

On the contrary, the floor decorative material manufacturing apparatus 100 according to the embodiment of the present invention passes through the transfer printing roll 130 by installing the rubber roll 160 and the emboss roll 170 at the rear end adjacent to the transfer printing roll 130. By minimizing the moving distance of the base sheet 1 on which the print layer 20 is formed, not only the sagging of the printed pattern of the print layer 20 can be minimized, but also through the tuning emboss without the addition of the glass fiber layer. By matching the printed pattern and the embossed pattern 40, it can be implemented to feel the three-dimensional, realism and luxury of the embossed pattern (40).

That is, the floor decoration apparatus manufacturing apparatus 100 according to the embodiment of the present invention measures the driving speed of the servo motor 176 and the servo motor 176 by adjusting the error of the printed pattern itself or the tuning error caused by the increase of the base sheet 10. Since it is possible to variably adjust the driving speed of the embossing roll body 172 in real time through the application of the embossing roll 170 having the motor control unit 178 to control, print pattern when applying embossing using the embossing roll 170 Since the matching of the embossed pattern 40 and the real-time control can be minimized.

In addition, the floor decorative material manufacturing apparatus 100 according to an embodiment of the present invention can not only maintain a constant distance between the rubber roll 160 and the emboss roll 170 through the gap adjusting unit 180, the rubber roll A constant force can be transmitted to the floor decoration material 1 passing between the 160 and the embossing roll 170, and is forced to the floor decoration material 1 passing between the rubber roll 160 and the embossing roll 170. Since it is possible to induce a slip, even if an error occurs between the printed pattern and the embossed pattern, it is possible to synchronize the printed pattern and the embossed pattern 40 by using the gap adjusting unit 180 and the embossing roll 170. .

Hereinafter, with reference to the accompanying drawings to describe a method for manufacturing a floor decoration according to the embodiment of the present invention.
