本発明は印刷された紙を印刷機の排紙側にて積み」二げ

裏面に付く裏移り防止の装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION When printed papers are stacked on the output side of a printing machine, the undried printing ink on the lower paper sticks to the back side of the paper on the second side. This invention relates to a device for preventing set-off.
従来裏移り防止のために、互いに相接する印刷された紙

であり、さらには印刷機械が汚れやすく、作業環境が悪
化する等の欠点がある。Conventionally, powder is interposed between adjacent printed papers to prevent set-off. This powder is spread onto the running printing paper before it is stacked. During this spraying, the powder scatters and has a poor adhesion rate to the paper, which increases the amount of powder used and makes it difficult to apply it evenly.Furthermore, printing machines tend to get dirty, which worsens the working environment. There are drawbacks such as:

しようとするものである。In view of the above, the present invention attempts to eliminate the above-mentioned drawbacks by charging the injected powder and the printing paper with mutually contradictory charges using an ion generating means, and causing the powder to be adsorbed to the printing paper.
以下本発明をその実施例で具体的に説明する。The present invention will be specifically explained below with reference to Examples.

紙用イオン発生袋@(5)が設けられている。The printing paper (1) is fed in the direction of the arrow, and there is a nozzle (3) that sprays powder (2) above it, and a powder ion generator that charges the sprayed powder with either a positive or negative charge. A device (4) is provided, and below is provided an ion generating bag for printing paper (5) that charges the printing paper with an electric charge opposite to that of the powder.

の流れを横断する正のイオン域(13が形成される。The ion generator for powder (4) is provided between the nozzle (8) and the printing paper (1), and has a discharge electrode (oriented at right angles to the powder flow direction) in the center of the insulating body (8). 9
), a ground electrode 00.00 opposing this electrode, and a high voltage generator 01). The above discharge electrode (9
) is connected to the anode of high voltage (gKV) generator 01), positive ions are generated and powder (2) is applied.
A positive ion zone (13) is formed across the flow of .

ることなく、パウダーの帯電を効率よく行う。While the powder (2) passes through this ion region 03, the powder is positively charged. When the electrodes (9) and 00 are arranged so that the ions face the direction of movement of the printing paper (1), the ions ride the airflow generated by paper feeding and efficiently charge the powder without being pushed back.

When a high voltage (23 to 30 KV) generator (10 cathodes) is connected and applied to the electrode α4, negative ions are generated and a negative ion area intersects from the bottom surface of the printing paper (1). This ion region G'71 is formed on paper (1).
By passing through, a negative charge is generated.

ことなく、付着力が減殺されない。As described above, the positively charged powder (2) is attracted to the negatively charged printing paper (1) by opposite positive and negative electrostatic forces and adheres to the paper surface. The powder is preferably sprayed at a position that is not directly above the electrode 0ψ, but at a position that is offset from directly above the paper in the traveling direction of the paper. If you take such a position,
The positively charged powder is not negatively charged in the negative ion region and its adhesion is not diminished.

の著しるしい向[−が得られ、集塵装置を省略できる。The present invention is configured so that the sprayed powder and printing paper are charged with mutually opposite positive and negative charges using an ion generating means, and the powder is adsorbed to the printing paper, thereby preventing the powder from scattering. The powder is distributed evenly, and the powder usage is significantly reduced (Vf
It is possible to reduce the amount of dirt on the printing machine, and it is easy to maintain and manage the printing machine, and a significant improvement in the working environment can be obtained, and a dust collector can be omitted.

。In addition, when the printing paper is piled up, there are no unevenness, and even if the paper side is turned over, the powder does not fall off the paper surface, so when printing on the other side, the powder that remained on the blanket, which was conventionally large, is significantly reduced. The number of washes is reduced, which improves the quality of printed products, reduces time loss, improves production efficiency, and reduces the burden on workers.
