Abstract
For a rapid and simple assembly, the rotary atomizer of the coating arrangement described has a fastening pin (34) arranged on a valve unit (12). The fastening pin is inserted into a matching opening of a mounting flange (70) and is retained therein by a clamping device that exerts a force pressing the valve unit (12) against the flange (70). The atomizer is composed of individual modules (2,4,6,10,12) connected by screw connections and additionally comprises a rigid light guide rod for the transmission of optical rpm measuring signals, which remains in the valve unit (12) during disassembly of the atomizer.
Claims15
A coating arrangement having a rotary atomizer comprising a spray element mounted on a rotating shaft, a drive motor for said spray element, and a stationary channel body which guides a coating material to be atomized or a rinsing agent to said spray element through channels running along an axis of rotation and is connected to a valve unit that comprises valve actuator for valves adapted for opening and closing said channels, and mounting means arranged on said valve unit for detachable mounting of said rotary atomizer on a mounting part of said coating arrangement, characterized in that a fastening pin is arranged on said valve unit, with an outer surface of said pin parallel to a longitudinal axis of said pin fitting into an opening provided in said mounting part, and in that means are provided for securing said pin in said opening with a force that draws said valve unit in an axial direction against said mounting part.
A coating arrangement having a rotary atomizer comprising a spray element mounted on a rotating shaft, a drive motor for said spray element, and a stationary channel body which guides a coating material to be atomized or a rinsing agent to said spray element through channels running along an axis of rotation and is connected to a valve unit that comprises valve actuator for valves adapted for opening and closing said channels, and mounting means arranged on said valve unit for detachable mounting of said rotary atomizer on a mounting pan of said coating arrangement, said arrangement further comprising a disk element for measuring rpm, which rotates with said shaft and a light guide that leads from said disk element through an intermediate space required for said valve unit to the mounting part of said coating arrangement, characterized in that an optical circuit is formed by said light guide retained by the valve unit and is detachable from said mounting part, said light guide being formed by a rigid light guide element.
