Electrostatic spray device
First Claim
1. An electrostatic spray device for spray-coating an article with coating material, comprising:
- a machine arm having a first hollow interior space defined therein, and being movable with respect to an article to be coated;
a carrier releasably mounted upon said machine arm, and having a second hollow interior space defined therein;
a plurality of gun barrels, releasably mounted upon said carrier, wherein each gun barrel has a third hollow interior space respectively defined therein, and forming with said carrier a respective plurality of spray guns;
a plurality of electrodes respectively disposed within said plurality of gun barrels;
a plurality of coating material supply lines for respectively supplying coating material to each one of said plurality of gun barrels;
a plurality of compressed air supply lines for respectively supplying compressed air to each one of said plurality of gun barrels; and
a plurality of electrical power supply lines for respectively supplying electrical power to said plurality of electrodes disposed within said gun barrels;
said plurality of coating material supply lines, said plurality of compressed air supply lines, and said plurality of electrical power supply lines all being disposed together as a bundle of supply lines within said first hollow interior space of said machine arm, divergently disposed within said second hollow interior space of said carrier so as to be respectively routed toward said plurality of gun barrels, and being respectively disposed within said third hollow interior spaces respectively defined within said gun barrels,whereby said plurality of coating material supply lines said plurality of compressed air supply lines, and said plurality of electrical power supply lines are all housed internally within said gun barrels, said carrier, and said machine arm so as not to hinder movement of said machine arm and said spray guns with respect to said article to be coated, or to adversely affect said coating material sprayed upon said coated article as a result of plurality of coating material supply lines, said plurality of compressed air supply lines, and said plurality of electrical power supply lines contacting said coated article.

Abstract
Electrostatic spray appliance for coating material for the spray-coating of articles comprises
a single carrier (4) which carries a plurality of gun barrels (6, 8), so that the carrier (4), together with the gun barrels, forms spray guns. The gun barrels (6, 8) are releasably fastened to the carrier (4). The supply lines (54, 56, 58, 60, 62, 64, 78) are combined to form a line bundle and are led through a movable robot arm (68) in the longitudinal direction of the arm on the side of the carrier (4) facing away from the gun barrels (6, 8). The spray nozzles (12) are preferably slit nozzles having slits arranged obliquely relative to their theoretical connecting line.
