Abstract

PURPOSE:To enable repeated patterns to be formed on an object to be printed without occasional drying operations by a method in which a table to fix an object to be printed or a printing head with a printing screen and a squeegee is moved, and relative positions of the object to be printed and the printing screen are changed repeatedly several times. CONSTITUTION:In an object 6 to be printed, having repeated patterns 4 and 5, for example, the object 6 is set on given places repeatedly by mechanisms 8 and 9 to move a table 7 to fix the object 6 toward the directions of X and Y, and screen-printing is made to form a repeated pattern on the object 6. In this case, by making the screen 3 smaller, the previously printed patterns are separated. Or, repeated pattern is formed by the mechanisms 8 and 9 to move a printing head 10 with the screen 3 and a squeegee 1. In this case, by making the distance between the screen 3 and the object 6 wider, the contact between the previously printed patterns and the screen 3 is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a screen printing machine, and more particularly to a screen printing machine capable of repeatedly forming a single pattern on a printing substrate a plurality of times.

(Prior Art) Conventionally, this type of screen printing machine forms repeated patterns on a printing screen, and forms all the patterns on a substrate in one go.

(Problems to be Solved by the Invention) The conventional screen printing machine described above forms a repeated pattern on the printing screen and forms all the patterns on the substrate in one go, so it is difficult to form a repeated pattern. The drawback was that a new screen had to be made in order to do so.

(Means for Solving the Problems) The screen printing machine of the present invention moves a table for fixing a printing material or a printing head to which a printing screen and a squeegee are attached in the X direction, the Y direction, and the rotation direction, It is constructed with a mechanism that repeatedly changes the relative position of the printing material and the printing screen multiple times, and uses a printing screen that is set so as not to touch the previously printed pattern. .

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a top view of a first embodiment of the invention. FIG. 2 is a sectional view of the first embodiment of the present invention. In this example, the printing substrate 6 with repeat]-patterns 4 and 5 is used.
At Vc, the printing material 6 is repeatedly set at a predetermined position by mechanisms 8 and 9 that can move the printing material fixing table 7 in the X direction and the Y direction, and a repeated pattern can be formed by screen printing. can. In this embodiment, by making the screen 3 smaller, it is possible to separate the previously printed pattern from the screen.

FIG. 3 is a sectional view of a second embodiment of the invention. This embodiment uses a mechanism 8 that can move a print head 10 to which a printing screen 3 and a squeegee 1 are attached in the X direction and the Y direction.
and 9, a repeating pattern can be formed by repeatedly setting the printing screen 3 at a predetermined position on the printing material 6 and performing screen printing. In this embodiment, by increasing the distance between the printing screen 3 and the printing material 6, contact between the previously printed pattern and the screen is prevented.

(Effects of the Invention) As described in Explanation 1-1 above, the present invention moves a table for fixing a printing material or a printing head to which a printing screen and a squeegee are attached in the X direction, Y direction, and rotational direction to fix the printing material. By repeatedly changing the relative position with the printing screen pattern multiple times, using a printing screen with a smaller screen frame size compared to the repeating interval, or increasing the distance between the printing screen and the printing material, it is possible to avoid printing first. By preventing the pattern from coming into contact with the screen, it is possible to repeatedly form a pattern on the substrate without drying it.

Claims (1)

[Claims] In a screen printing machine that uses a squeegee to extrude ink placed on a printing screen to form a predetermined pattern on a printing material, there is a means for repeatedly changing the relative position of the printing material and the printing screen pattern multiple times, and a means for repeatedly changing the relative position of the printing material and the printing screen pattern. What is claimed is: 1. A screen printing machine, comprising means for preventing the pattern from coming into contact with a screen, and capable of repeatedly forming a pattern on a substrate multiple times without drying.
