The present invention relates to a rotary printing machine having a multi-processing function, and more specifically, to a rotary printing machine having embossing and foiling functions integrally so that dyeing, embossing and foil processing can be performed in one process.

Printing refers to a process in which dyes or pigments are added to a viscous liquid (hereinafter called dyes) in a viscous solution and partially inlaid on the fabric to be dyed to perform as a means for designing various patterns and colors.

The printing is a kind of dyeing that is performed in combination with dyeing by dipping textile paper in a dye solution and dyeing only the same color on the textile paper, and the printing is a situation that is widely used because it can express multiple colors using multiple colors.

Such printing uses a variety of methods and apparatuses, but typical examples of the printing and the printing between the roller and the press roller is a pattern and shape, and the continuous transfer to the paper by the dye contained in the roller or dye supplied to the roller Roller roller base to be made,

When the fabric is supplied through the endless belt, and a screen is attached to the rotary drums of the plurality of printing drums formed on the endless belt, and the dye is supplied into the printing drum, the dye is transferred to the squeegee or the magnetic roller installed inside the printing drum. Rotary screen printing machine to pass through and print on the fabric,

The cloth is supplied through the endless belt, and the screen is fixed to the plate-shaped mold having a hollow portion on the endless belt, and is classified into a flat screen printing machine to be printed on the fabric by a squeegee reciprocating by adding dye thereon.

In the case of the rotary printing machine of the above printing machine is used because it has a certain speed and excellent productivity, but because of the precision and in-depth color expression close to the flat screen printing machine is possible.

Such rotary blade base as shown in Figure 1,

The squeegee and the magnet roller (hereinafter referred to as squeegee) set inside by supplying the dye inside the rotary screen 10 squeeze the dye so that the fabric moving by the endless belt 5 is dyed. .

As described above, the dyed fabric may be processed by forming embossed irregularities by passing the fabric through an embossing roller provided in the embossing machine for the purpose of creating a high value added or better design.

In particular, for example, in the case of a fabric having a leaf-shaped design, it is to increase the added value of the product by allowing the leaf-shaped portion to protrude or uneven.

As mentioned above, in order to emboss after dyeing, the embossing line should be installed separately from the dyeing machine, or the embossing line should be installed in a separate place. In this case, the installation space and the installation cost must be secured. There have been several problems, including weakened competitiveness and a lack of fit for the current textile industry in recession.

In addition, since it is difficult to accurately set the position of the printed design portion of the pre-printed printing machine and the embossing roller of the embossing machine, the embossing is shifted from the position to be embossed, and thus, it is a major factor that lowers the quality of the product.

In order to solve the problems described above, the present invention is embodied as an embossing function and a foiling function to perform an embossing function on a rotary printing machine, so that embossing and foiling are possible at the same time as a separate installation space and The aim is to be able to digest both processes into one process without excessive investment cost, so that it can secure competitiveness with low production cost.

Further, in order to eliminate the error between the printing position by the printing driving roller and the embossing position by the embossing roller, the printing driving roller and the embossing roller are AC servo motors, and the correction value from the error sensor on the embossing roller side is adjusted. By controlling in the main processor to vary the drive value of the AC servo motor is configured to synchronize the printing shape and embossing.
