The rolls are rotatably pivoted at regular intervals in the horizontal direction, the static elimination brushes are vertically arranged in the film width direction above the middle part of both guide rolls, and the ground cord is attached to the base for roll film printing. Cleaning static eliminator.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cleaning static eliminator which removes dust adhering to a roll film during printing of the roll film and then removes static electricity charged on the roll film.

[0002]

[Prior art]

 In the past, when printing a roll film, static electricity charged in the air was removed by corona discharge.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional technology, since static electricity was removed by corona discharge, the size of the entire apparatus was increased, and it was difficult to move the apparatus according to vertical printing and horizontal printing.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is provided with two horizontal shafts vertically spaced from the L-shaped base side wall, and a cleaning brush is arranged on the inner surface facing each other in the width direction of the film to contact the tip. Then, two guide rolls are rotatably attached to the rear of the horizontal shaft so as to be rotatable at regular intervals in the horizontal direction, and an antistatic brush is vertically arranged in the film width direction above the middle portion of both guide rolls. Is equipped with an earth cord.

【Example】

 Next, one embodiment of the present invention illustrated will be described in detail. Reference numeral 1 is an L-shaped base. Two horizontal shafts 2 and 3 are attached to the upper and lower sides of the side wall 1a at slightly narrower ends, and rectangular cleaning brushes 4 and 5 made of horsehair are formed on the inner surface facing each other. They are arranged in the width direction, and the degree of contact is increased as the free end is brought into contact with the tip. Behind these horizontal shafts 2 and 3, two guide rolls 6 and 7 are rotatably pivoted at fixed intervals in the horizontal direction so that their upper ends are located in the brush contact portions. A rectangular static elimination brush 8 is vertically arranged in the film width direction, and one end of an earth cord 9 is attached to the L-shaped base 1.

Next, the usage method will be described. The roll film feed direction is determined depending on whether the roll film 10 is printed vertically or horizontally. The L-shaped base 1 is arranged in a predetermined direction according to the feeding direction. Then, the roll film 10 is passed between the cleaning brushes 4 and 5, placed on the guide rolls 6 and 7, and transferred forward. The dust adhered to the roll film 10 is cleaned by the cleaning brushes 4 and 5. At this time, the static electricity generated on the roll film 10 flows to the next charge eliminating brush 8 and is discharged into the air by the earth cord 9. Horse hair is suitable for the cleaning brushes 4 and 5 for cleaning dust, but other materials may be used.

[0007]

[Effect of device]

 According to the present invention, two horizontal shafts are attached at regular intervals above and below the side wall of the L-shaped base, the cleaning brushes are arranged in the film width direction on the inner surfaces facing each other, and the tips are brought into contact with each other. Book guide rolls are rotatably pivoted at regular intervals in the horizontal direction, static elimination brushes are vertically arranged in the film width direction above the middle parts of both guide rolls, and an earth cord is attached to the base. The roll film can be arranged by changing the orientation of the base according to the transfer direction in both vertical printing and horizontal printing, and since the corona discharge device is not required as in the past, the entire device can be downsized. .
