Abstract: Coating zones having guide elevated rails for coating and/or handling robots have walk-in control areas positioned one above the other on the outside of the side walls. In the upper control area, in which control and supply devices for the robots on the elevated guide rails, the side wall slants inward. The load-bearing structures for the elevated guide rails are braced by supporting members extending perpendicular to the line of conveyance of the application objects on or under the floor level or at the ceiling.

Abstract: The bell shaped plate of a rotary sprayer is attached to its drive shaft by means of a detachable device. An accidental self-release of the mounting device that would cause the rotating bell shaped plate to be flung off is avoided by measures that prevent at least accidental movements of the bell shaped plate radial to the axis of rotation.

Abstract: A dual action piston type metering device is installed between the color changer of a coating system and its atomizer, the metering cylinder of which includes two input ports with the color changer output ports connected to the atomizer. The dual action piston type metering device enables the alternating operation of the cylinder ranges (A/B-operation) with only one single metering cylinder.

Abstract: To clean an atomizer used for automatic series-production coating of work pieces in a cleaning device provided for this purpose, the outer housing of the atomizer is sprayed by nozzles of the cleaning device, while simultaneously painting and rinsing agents sprayed by the spray head of the atomizer in a short rinsing process are captured and discharged through a pipe section in the interior of the cleaning device. In electrostatic atomizers, voltage equalization between the atomizer and the cleaning device is performed beforehand. Through additional measures, the atomizer can be moved by the handling machine provided for this purpose only from one proper direction towards the cleaning device.
