JP4322911B2 - Static elimination transport device for liquor bottles, cosmetic bottles, and resin molded products - Google Patents

Description

  In the present invention, the dust adhering to the surface caused by static electricity in liquor bottles, cosmetic bottles, and resin molded products is blown away by blowing high-pressure ionized air that neutralizes static electricity, and the workpiece is conveyed. The present invention relates to a bottle dust removing and conveying apparatus.

Plastic trays for packing food cannot be used immediately for hygiene because the plastic sheet of the material tends to be charged with static electricity during the molding process, and molding powder and dust adhere to it. Therefore, while transporting the stacked plastic tray molded products with a net conveyor that is sandwiched between press frames, ionized air is injected from the air nozzle provided above to separate the molded products one by one and blow off dust. There is an invention in which dust is collected by a hopper provided below the air nozzle. For example, Japanese Patent Laid-Open No. 2002-346492.

Also, there is provided ionized air generating means and ionized air spraying means for blowing ionized air onto the surface of the resin molded product without providing a dedicated dust removal process for dust adhering to the surface of the automobile bumper during machining of the resin molded product. There is an invention in which ionizing air is blown from above and from both the left and right sides of the automobile bumper along the conveying direction of the pallet on which the automobile bumper is mounted. For example, Japanese Patent Laid-Open No. 7-22193.
