Abstract
A dosing device for a program controlled spray painting apparatus adapted for dosing electrically conductive fluid materials to a spray gun/applicator. The spray gun may be charged at a high voltage for electrostatically charged atomizing of electrically conductive fluid materials. A coating system includes the dosing device, which is moved by an actuator between a connecting member for a paint filling line or a cleaning fluid supply line, and a spray gun. A method and a computer program for carrying out the method.
Claims16
A program controlled spray painting apparatus to electrically dose conductive fluid materials to a spray gun/applicator, the spray gun/applicator comprising a high tension electrode that electrostatically charged atomizes electrically conductive fluid materials supplied thereto, the spray painting apparatus comprising:
- a dosing device comprising an inlet conduit through which fluid material and cleaning liquid are alternatively supplied, the dosing device further comprising an outlet conduit to alternately deliver said fluid material and cleaning liquid to, respectively, the spray gun/applicator and a sump for spent cleaning liquid, wherein said dosing device is arranged mounted on a robot arm and movable to connect and disconnect the inlet conduit to a supply connection of said fluid material and cleaning liquid mounted on the robot arm and to connect and disconnect the outlet conduit to the spray gun/applicator and a sump for spent cleaning liquid, wherein said dosing device is movable in relation to the robot arm, and wherein the dosing device is movable in relation to the spray gun/applicator, the sump, the supply connection of said fluid material and cleaning liquid, and wherein the dosing device is arranged movable by an actuator member along a path between the supply connection and a connection point to the spray gun/applicator.
A program controlled spray painting apparatus to electrically dose conductive fluid materials to a spray gun/applicator, comprising:
- a spray gun/applicator;
- a sump for spent cleaning liquid mounted on a robot arm;
- a supply connection of said fluid materials mounted on the robot arm;
- a supply connection of cleaning liquid mounted on the robot arm;
- a high tension electrode that electrostatically charged atomizes electrically conductive fluid materials supplied thereto;
- and
- a dosing device comprising an inlet conduit through which fluid material and cleaning liquid are alternatively supplied, the dosing device further comprising an outlet conduit to alternately deliver said fluid material and cleaning liquid to, respectively, the spray gun/applicator and the sump, wherein said dosing device is mounted on the robot arm and is movable in relation to the robot arm so as to connect and alternatively disconnect the inlet conduit to the supply connection of said fluid material and cleaning liquid and connect and alternatively disconnect the outlet conduit to the spray gun/applicator and the sump, and wherein the dosing device is movable in relation to the spray gun/applicator, the sump, the supply connection of said fluid material and cleaning liquid.
