摘要： An air atomizing electrostatic coating gun which atomizers a liquid paint by using air flows and thereafter applying atomized liquid paint to an object to be coated by using an electrostatic force. In this coating gun, all of a rod valve, a driving piston, an air cylinder and valve support members of a needle valve device are made of insulating materials having good insulating properties, and an electrode for charging paint particles is attached to the valve. A nozzle-needle valve assembly which is integrally constructed by attaching a paint nozzle to a cylindrical extension of the air cylinder which is formed at a front end portion thereof, is inserted and fitted into a generally cylindrical cavity in a front end portion of the gun body from the front side thereof. An integral molded body incorporating a direct current high-voltage power source is formed by molding a synthetic resin having good insulating properties to embed therein a boosting high-voltage transformer, a rectifier type direct current high-voltage generator and a spiral-wound flat high-resistance element, and this integral molded body is detachably attached and fixed inside of the gun body by inserting it into a cavity formed in a rear end portion of the gun body from the rear side thereof.

摘要： A rotary electrostatic atomizer uses shaping air and pattern control air. Shaping airflow is supplied from shaping air holes aligned along outer one of concentric circles that are concentric with the rotation axis of the bell cup and located behind the front end of the bell cup. Pattern control airflow is supplied from pattern control air holes aligned along inner one of the concentric circles. Both the shaping air flow and the pattern control airflow are expelled in circumferentially twisted directions substantially with an equal twist angle opposite from the rotating direction of the bell cup. The shaping airflow passes a circular line near to and radially outwardly apart from the outer perimeter of the bell cup. The pattern control airflow intersects the shaping airflow from radially inside at the position near to and radially outwardly apart from the outer perimeter of the bell cup. Thereby, the pattern control airflow gives the shaping airflow a radially outward force to enhance the centrifugal force of the shaping air and enlarge the coating pattern regulated by the shaping airflow.

摘要： An arm of a coating robot is used to prevent external leakage of a high voltage. A tank is installed on a robotic arm and contains water as an actuating liquid. The water is supplied to a paint cartridge by a pump controlled by a controller. The water sent from the pump under pressure is supplied to the paint cartridge by a conduit tube. A high voltage generator and a bleeder resistor are combined with the tank such that a high voltage generated by the high voltage generator is supplied to the electrostatic paint applicator via the water. For replenishment of water to the tank is attained by relatively connecting a nozzle in communication with a water source to a main pipe. While the high voltage generator generates a high voltage, the nozzle and the main pipe are kept disconnected to maintain electrical insulation between the nozzle and the main pipe.
