摘要:
An electrostatic coating product spraying device comprising: at least one sprayer having an electrostatic charging mechanism; and a support structure supporting the at least one sprayer, the structure including elements which are at ground potential, wherein the support structure includes an electrostatic shield positioned and arranged so that the electrostatic charging mechanism is located between the electrostatic shield and an object to be coated. The electrostatic shield is maintained at a potential differing from ground potential.
摘要:
The invention concerns painting installations comprising painting machines or robots (6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b), each with a sprayer (12) and a paint reservoir (13), associated with the sprayer and designed to supply it, the machines or robots being arranged along a painting line for motor vehicle bodies (2). Each machine or robot is provided with a fluidic connector, designed to co-operate discontinuously with a dispensing system (14a, 14b, 15a, 15b) comprising a color shade-changing unit. Each dispensing system (14a, 14b, 15a, 15b) is arranged between two consecutive machines (6a, 7a; 6b, 7b; 8a, 9a; 8b, 9b), and is common to those two machines, which are successively connected thereto to fill their respective reservoirs each time there is a color shade change.
