A rotary atomizing head enables cleaning by decomposing from the atomizing head, and enables internal cleaning without decomposing to individual components when paint is changed to a new one of another color. A structural component has a front wall acting as a hub, side wall extending rearward from an outer circumferential perimeter of the front wall to make a circumferentially continuous plane, legs each having a pawl and a bottom wall. The structural component is detachably mounted in a central concavity of an atomizing head body. A bottom wall of the structural component has formed a spoon-cut recess. The central concavity has an inclined circumferential wall, and the side wall of the structural component has an inclined outer circumferential surface complementary with the circumferential wall of the atomizing head body to get in substantial contact with the circumferential wall throughout the entire area of the outer circumferential wall.

A rotary atomizer headwith a bell-shaped atomizer head bodyand a functional memberremovably attachable thereto, which can be more easily and reliably positioned, and cleaned. The functional memberhas a front wallthat has paint outlets, a sidewallof the paint space S extending continuously in a circumferential direction, and a plurality of legshaving claws, which engage with a circumferential grooveformed in a peripheral wallof a central recessof the atomizer head body. The peripheral wallof central recesshas an inclined wall. The sidewallhas an outer circumferential surfaceand an inner circumferential surface, wherein the peripheral walland outer circumferential surfacehave complementary configurations.

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.

Rotary atomizer and coating pattern control method

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.
