Abstract: 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.

Abstract: A rotary atomizer head 1 with a bell-shaped atomizer head body 2 and a functional member 4 removably attachable thereto, which can be more easily and reliably positioned, and cleaned. The functional member 4 has a front wall 12 that has paint outlets 24, a sidewall 14 of the paint space S extending continuously in a circumferential direction, and a plurality of legs 16 having claws 16a, which engage with a circumferential groove 18 formed in a peripheral wall 8 of a central recess 6 of the atomizer head body 2. The peripheral wall 8 of central recess 6 has an inclined wall. The sidewall 14 has an outer circumferential surface 14a and an inner circumferential surface 14b, wherein the peripheral wall 8 and outer circumferential surface 14a have complementary configurations.

Abstract: 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.

Abstract: A functional member removably attachable to an atomizer head body 2 is described. The functional member 4 has a sidewall 14 extending continuously in a circumferential direction, a plurality of legs 16 having claws 16a, and a circumferential projection provided radially inward of the legs 16. The circumferential projection 20 sits on an outer circumferential portion of a circumferential seat 22 of head body 2 and in abutment with an outer circumferential surface of the circumferential seat 22. A peripheral wall 8 of a central recess 6 head body 2 is an inclined wall, and an outer circumferential surface 14a of member 4 inclines to be complementary with the inclination of the peripheral wall 8 such that the outer circumferential surface of the member 4 can be substantially in contact with the peripheral wall 8 of the central recess 6 throughout the entire area of the member 4.

Abstract: 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.
