  • Patent number: 8840050
    Abstract: For grounding or electrically charging the shaft of an electrostatic rotary atomizer working with external or direct charging, there are opposing, annular or spiral-shaped sharp edges in the outer surface of a part of the shaft and in the inner surface of a stationary bearing part at the desired potential, which have different, preferably opposite, thread directions, so that the edges intersect each other at points.

  • Patent number: 7721976
    Abstract: An atomizer assembly (10) drives an atomizing bell (108) to apply paint onto a part (14). The atomizer assembly (10) includes a core (24) having at least one paint line (26) extending therethrough, a turbine device (40) circumscribing an axis (A) and disposed in the core (24), and a turbine unit (62) surrounding the pain line (26) and having a shaft (104) rotatable relative the turbine device (40) with several turbine blades (130) connected to the shaft (104). A plurality of nozzles (64, 66, 68) are defined in the turbine device (40) and are positioned relative a turbine wheel (106) connected to the shaft (104) to drive fluid, i.e. gas onto the turbine blades (130). An annular wall (94) extends outwardly from one of the terminal ends of the turbine device (40) to define a seat (96) for engaging the core (24) to maintain a fixed gap between the paint line (26) and the shaft (104) and to eliminate contact therebetween.

  • Patent number: 7322793
    Abstract: A turbine, e.g., with a blade arrangement, which receives an air flow in the radial direction and which is located on a carrier surface of the turbine wheel, is used as a drive motor for a rotary atomizer. The drive channel, which contains the turbine blades and which is limited by the carrier surface, is also closed on its other side by a cover element, which is attached to the turbine wheel and which rotates with the wheel for increasing efficiency. For an additional increase in efficiency, the inlet for the drive air of the turbine is configured as an ultrasonic nozzle with a cross section that expands continuously up to the opening.

  • Patent number: 7156795
    Abstract: A plurality of atomizers or other tools are disposed in a mounting plate (10) in storage places (12), respectively. The mounting plate (10) is rotatable relative a paint robot of a coating installation and has a pneumatic lock or a tool holder (19) that can only be released automatically during storage of the atomizers by an external control device of the mounting plate.

  • Patent number: 7131601
    Abstract: A rotational atomizer turbine of the present invention is designed to drive a bell-shaped disk in a rotational atomizer for a coating unit. The rotational atomizer turbine includes a housing, a rotatable turbine wheel with several turbine blades connected to a shaft and rotatably disposed in the housing. A plurality of nozzles are defined in the housing and are positioned relative the turbine wheel to drive fluid, i.e. gas onto the turbine blades. An intermediate chamber formed in the housing is fluidly communicated with and connected to the nozzles to hold gas therein. The intermediate chamber has a first inlet to supply gas. At least a second inlet is defined in the intermediate chamber for delivering gas into the intermediate chamber thereby increasing amount of gas therein to multiply a rotational speed of the rotatable turbine wheel as increased amount of gas is introduced to the turbine blades.

  • Patent number: 7051950
    Abstract: The atomizer (Z) of an electrostatic coating unit contains a dosing pump (DP) connected between the atomization device (4) and a scrapeable coiled pipe (10) which serves as a space-saving paint supply vessel and which is also situated in the atomizer. The scraper (12) is activated by compressed air on one side in order to force the paint material fed to its other side to the dosing pump (DP), which conveys it to the atomization device (4).
