Description

[0001] Silk screen printing apparatus [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silkscreen printing apparatus, and more particularly, to a silkscreen printing apparatus that sequentially performs a silk screen printing process on a surface of a printed material to form a multicolored print layer on the surface of the print, The present invention relates to a silk screen printing apparatus in which a single monochromatic printing process is implemented so as to ensure continuity of operations according to silk screen printing.

As is known, silk-screen printing is a kind of stencil printing method similar to a spine board. Silk screen printing, which is commonly known, is a method in which a cloth (silk) is stretched in a rectangular mold, and then a photosensitive resin is left except for a portion to be printed on a cloth to complete a mold of a stencil.

Thereafter, the printed matter is placed on the lower part of the mold, the ink is uniformly applied by a scraper, and the paste is uniformly pressed onto the cloth through a squeeze made of rubber, It is a method of printing.

On the other hand, generally used silk screen printing is performed by moving the squeegee and the scraper along the pattern of the film installed on the screen and performing printing on the upper surface of the printed material and drying the printed printed material, This is because a variety of materials can be printed and the use range thereof is widely used.

In recent years, an automatic, semi-automated silk screen printing machine has been developed to improve such silk screen printing by hand. As an example, Korean Patent Registration No. 10-0732917 discloses a semi-automatic screen printing machine, A printing unit including a scraper and a squeeze positioned on the upper side of the seating unit; conveying means for conveying the scraper and the squeeze; and conveying means for conveying the scraper and the squeeze, Pressure supply unit. And vertical transporting means connected to the scraper and the squeeze and having two or more vertically transporting cylinders vertically feeding the squirper and the squeezer by receiving high pressure air from the pneumatic supply portion, A horizontal conveying cylinder connected to the scraper and the squeeze for receiving horizontally the scraper and the squeeze,

And a sliding plate, which is slidable by the horizontal transfer cylinder and to which the vertical transfer cylinder is coupled, wherein the screen is fixed to the seat And an opening / closing frame coupled to be positioned between the printing unit and the printing unit.

However, in order to perform silk screen printing in the related art, a printing apparatus for performing printing and a drying apparatus for drying the printed material printed through the printing apparatus are separately constructed, which causes a problem that continuous operation is not performed.

In addition, the printing operation in the printing apparatus is performed by manual operation of the operator from the setting to the printing process. In addition, after the printing operation is completed, the drying operation is carried out by the operator again after the drying operation. There have been problems in that the working efficiency has been remarkably deteriorated as well as causing several troublesome problems.

The most serious problem in conventional silkscreen printing is that only a monochromatic printing operation is performed in the printing and drying operation steps. Therefore, when a plurality of colors are to be printed in a single printing operation, the printing operation and the drying operation It is almost inconvenient to expect the increase in productivity as a result.

In addition, since the monochromatic printing process is completed and the printed matter is set to print another color, an artificial setting is performed by the manual operation of the operator, so that the accurate setting is not performed and a lot of defects are also generated.

It is an object of the present invention, which has been devised to solve the above-mentioned problems, to sequentially form a silk screen printing process on the surface of a printed material to form a multicolored print layer on the surface of the printed material, A monochromatic printing process is implemented so that the continuity of the operation according to the silk screen printing is ensured,

In particular, the printed matter is loaded and discharged onto the rotary table in a state where the printed matter is arranged in the loading jig in a proper position by the improved loading structure, so that the alignment state of the printed matter is stably maintained, And to provide a silk screen printing apparatus capable of minimizing the occurrence of defects according to the present invention.

The loading jig 40 is provided with a vacuum adsorption unit 42 for vacuum adsorbing the printed material 100 seated in the receiving groove 41 and a vacuum adsorption unit 42 for irradiating the vacuum adsorbed printed material 100 with ultrasonic waves, And the printed matter 100 which is disposed on the loading jig 40 and rotates in a constant angle in one direction is instantaneously heated by the irradiated ultrasonic waves.

Accordingly, the printed matter 100 instantly heated by the loading jig 40 is rotated in a state of being mounted on the loading jig 40 by the rotation of the rotary table 11 and passes through the respective printing head modules 20 , And a multi-color screen printing layer formed by stepwise performing monochrome printing on the surface is formed.

Thus, the multi-color silkscreen printing apparatus 1 according to the present invention can eliminate troublesome setting operations in which the operator moves and sets the prints for each printing step, so that manpower can be reduced by the silk screen printing, It is possible to prevent a phenomenon in which the arrangement of printed matter is disturbed and defects are generated.

In the present invention, in implementing the multi-color silkscreen printing apparatus, a printed material 100 requiring printing and a unique loading structure for promoting the formal discharge of the printed material after printing are provided, And is loaded into the rotary table 11 in a state where the loading jig 40 is arranged in the form of a standard.

When the printed matter is fixedly arranged and fixed on the loading jig 40 and then supplied to the rotary table 11 as in the present embodiment, the phenomenon that the printed matter 100 is damaged or deformed in the process of aligning the printed matter 100 on the rotary table 11 is prevented And is inserted into the rotary table 11 in a state in which the jig 40 is fixedly arranged and spread in a taut manner, so that occurrence of defects due to misalignment of the printed matter can be suppressed.

The loading unit 30 disposed on one side of the rotatable rotary table module 10 rotates the rotary table 11 by placing the printed matter 100 requiring printing on the loading jig 40, And is configured to discharge the loading jig 40, which is fixed to the rotary table 11, which rotates in an equidirectional manner, and sequentially passes through the respective print head modules 20, .

Here, the loading unit 30 includes a loading table 31 that rotates in conjunction with an index 12, A loading table 33 arranged in conformity with the loading table 31 and aligned with a table 13 formed on the rotating table 11 by an angular rotation of the loading table 31; And a loading unit 34 for moving the loading jig 40 between the loading table 33 and the loading table 13 formed on the rotating table 11 aligned in the row.

For example, in the present invention, the loading unit 34 is constituted by an advancing / retreating cylinder having an electromagnet formed at its end, so that the loading jig 40 can be moved forward and backward by the forward and backward movement of the piston.

In this embodiment, the loading jig 40 is provided with a seating groove 41 for providing a seating space for the printed material, and a moving roller 44 at the bottom.
