At the same time, static electricity is charged onto the welded films. Next, powder, which is positively charged by means of corona discharge developed between the discharge electrode 23 and the earth electrode 24 of a first powder dusting device 5 is blown by the forced draft of a blower 15 against the underside of the welded films so as to attract the power by means of the negative static electricity charged on the respective films, and the powder is adhered onto the underside of the films. Next, the powder, which is positively charged with a second powder dusting device 6, is blown against the top surface of the films, the powder is attracted by means of the enfeebled static electricity on the film side, and the powder is attracted onto the top surface of the films by means of the forced draft of the blower 15 and the own weight of the powder.

(Prior technology) Plastic films made of vinyl chloride are often used in agricultural and industrial greenhouses.
Two or more films are joined in the longitudinal direction, or a long plastic tape is joined to the end of the film, and the films are folded and packed together for storage. If films are kept in close contact with each other for a long time in this way, blocking occurs and they stick to each other, making it extremely troublesome to peel them off, so conventionally, powders such as starch are sprinkled on the film surface before folding the film. Mutual blocking of the films was prevented.

Conventionally, when scattering powder in this way, the powder was dispersed in the air in a blower and then sprayed together with the air from a nozzle onto the film surface. However, in order to achieve uniform spraying, it is possible to increase the air jet speed of the nozzle or extremely increase the number of nozzles, but both of these methods consume a larger amount of powder than necessary and are uneconomical. Instead, the excess powder was blown up by the air flow, resulting in dust that degraded the working environment.

The scattering device is provided on the downstream side of the film and the plastic member that have been fused together by the bonding device, and uses static electricity charged on the film and the plastic member during high-frequency dielectric heating to forcibly adhere the powder to the film and the plastic member. The spraying device includes a device for forcibly spraying the powder, and a device for charging the powder with static electricity of opposite polarity to the static electricity charged on the film or the like. The device is
Preferably, the powder sent by a forced air stream is charged with a predetermined static electricity by corona discharge. When using corona discharge as described above, it is preferable to provide a discharge electrode near the blowout position of a nozzle for spraying powder onto a film or the like to be sprayed, in order to effectively charge the powder. The spraying devices are preferably provided on both sides of the film, etc., and are provided at positions facing each other or spaced apart from each other. In this case, when scattering the powder while feeding the bonded film horizontally, it is preferable to first spread the powder on the lower surface and then on the upper surface. If you sprinkle powder that is charged with the opposite polarity to the static electricity charged on the film onto the top surface of the film, etc., the static electricity on the film will be neutralized and the charged state will become weaker. Since it becomes difficult for the powder to adhere, sprinkle the powder on the bottom side first to force it to adhere electrostatically.
After that, the powder is spread on the upper surface side, and the powder is adhered by using the forced air blowing of the powder, its own weight, and a weak electrostatic charge.

(Effects) According to the present invention, when bonding plastic films together or bonding a plastic film to another plastic member, a bonding device using high-frequency dielectric heating is used, and static electricity that is charged on the film during bonding is utilized to eliminate the static electricity. Powder charged to the opposite polarity is sprayed with a powder scattering device and forced to adhere, so the powder can be evenly attached to the film, and there is no need to spray excessive powder onto the film, so excess powder can be used for work. It is effective to provide a plastic film bonding device equipped with a powder scattering device that does not pollute the environment and has a simple structure because it does not require a device to charge static electricity on the film side.
