An electrostatic atomizerhas a removably attachable canister. Once a paint baghoused in the canisterexhausts, it is replaced by a new canister. Paint in a paint bagis driven out by a mono pumplocated in a pump segmentof the electrostatic atomizer. The mono pumphas a helical shaftinside a paint feed tube. The mono pumpis driven by a servomotor via an insulating drive shaft. Paint in the paint bagis drawn up when the helical shaftrotates, and it is delivered to a bell cupthrough the feed tube. Quantity of paint atomized by the bell cupand interruption of the atomization are controlled by controlling the rotation of the mono pump

Electrostatic atomizer and its cleaning method

An apparatus for replenishing paint into a paint cartridge ( ), which is capable of putting paint in respiratory circulation while the cartridge is in a waiting state. The apparatus includes a replenishing valve ( ) which is capable of feeding paint to and from a paint chamber ( ) of the paint cartridge ( ) which is set on a replenishing stool ( ), and a respiratory paint circulation valve ( ) which is capable of feeding paint-extruding thinner to and from a thinner chamber ( ) of the cartridge. After switching the replenishing valve ( ) to a drain or discharge side, paint-extruding thinner is supplied from the respiratory paint circulation valve ( ) to push paint out of the paint chamber ( ) of the cartridge ( ). Then, after switching the replenishing valve ( ) to the side of a paint supply source, paint-extruding thinner is discharged by way of the respiratory paint circulation valve ( ) to suck paint into the paint chamber ( ). As a consequence, paint in the cartridge ( ) is put in respiratory circulation to prevent separation and sedimentation of pigment components of the paint.

Cartridge paint-charging method and device therefor

A method of applying water-base paint in which a solvent which increases the viscosity of water-base paint is sprayed on the article to be painted before or after the application of the water-base paint, or at the same time as its application, or a paint compounded with a solvent which increases the viscosity of the water-base paint is sprayed on the article before or after the application of the water-base paint or at the same time that it is applied.
