Abstract

PURPOSE:To obtain clean printed face by automatically removing stains, dust, glass chips, etc., adhered to an object to be printed before printing by providing a cleaner unit consisting of an adhesive rubber roller and a driver for the roller. CONSTITUTION:A cleaner unit 6 is provided with an air cylinder 7 and an adhesive rubber roller 8 rotatably attached to an operating rod 7a. When the rod 7a is reciprocally moved, the roller 8 passes while being turned in contact with the surface of an object 2 to be printed, whereby removing stains, dust, glass chips, etc., adhered to the printed face of the object 2 by means of the roller 8. Since printing is made after cleaning up the object 2 to be printed by the roller 8, clean printed face can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an octopus printing machine, and for example, to an octopus printing machine that prints characters, numbers, and figures on a liquid crystal display element.

[Background of the invention]

Conventional octopus printing machines are dedicated machines for the sole purpose of printing, and do not have a cleaning mechanism for the printing material, so the print quality deteriorates due to dirt on the printing surface, dust, and glass chips getting caught in the printing surface. There was a problem.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an octopus printing machine that can automatically remove dirt, dust, glass chips, etc. attached to a printing material immediately before printing, and can obtain a clean printing surface.

[Summary of the invention]

In order to achieve the above object, the present invention includes an adhesive rubber roller, and an adhesive rubber roller driving means that rotatably holds the adhesive rubber roller and reciprocates just before printing so that the adhesive rubber roller rotates while contacting the surface of the printing material. It is characterized by being equipped with four cleaner units consisting of.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG. The octopus printing machine main body 1 includes a suction base 3 that suctions and holds a printing material 2 such as a liquid crystal display element, an octopus holding member 4 that moves up and down by means not shown, and a silicon octopus 5 fixed to the lower end of the octopus holding member 4. and has. The above is a conventionally known structure.

In the present invention, a cleaner unit 6 is attached to an octopus printing press main body 1. The cleaner unit 6 includes an air cylinder 7 and an adhesive rubber roller 8 rotatably attached to an actuation rod 7a of the air cylinder 7. Further, the tacho printing machine main body 1 is provided with a photoelectric switch 9. This photoelectric switch 9 is installed as a safety device to avoid the danger of the adhesive rubber roller 8 moving forward while the printing material 2 is being loaded and positioned on the suction base 3.

Next, the operation will be explained with reference to FIG. First, the same figure til
When the printing material 2 is loaded and positioned on the suction base 3 as shown in 1), the vacuum of the suction base 3 is activated, and the printing material 2 is suctioned and fixed to the suction base 3. In this state, when the actuating rod 7a of the air cylinder 7 reciprocates as shown in FIG. Dirt, dust, glass chips, etc. on the printing surface are removed by adhering to the adhesive rubber roller 8. When the return of the operating rod 7a is confirmed, the silicon octopus 5 descends to move the printing material 2 as shown in FIG. Press it onto the top surface and print.Once the printing is complete, the silicone octopus 5 rises.
While further retreating and picking up ink, the printed material 2 is unloaded as shown in FIG. 2(d). When the loading of the next printing material 2 is completed again, the silicon octopus 5 also returns to its initial position and repeats the series of operations described above. This series of operations is sequence-controlled without interfering with each other.

In this way, since printing is performed after wiping off dirt, dust, and glass chips on the surface of the printing material 2 with the adhesive rubber roller 8, a clean printing surface is obtained and the yield is improved. Furthermore, when the printing material 2 is made of glass material such as a liquid crystal display element, rapid deterioration of the ink plate caused by adhesion of glass chips and damage to the ink scraping blade are eliminated, improving the operating rate. .

Note that the adhesive rubber roller 8 becomes dirty due to repeated operations, so it goes without saying that it needs to be replaced from time to time.

〔Effect of the invention〕

As is clear from the above description, according to the octopus printing machine of the present invention, the adhesive rubber roller is rotatably held, and the adhesive rubber roller is rotated in contact with the surface of the printing material immediately before printing. Since the printer is equipped with a cleaner unit consisting of a reciprocating adhesive rubber roller drive means, dirt, dust, glass chips, etc. are not caught in, a clean printing surface is obtained, and quality and yield are improved.
