Abstract

An installation for spraying a multi-component coating material composed of at least one robot having a moving portion carrying at least one electrostatic sprayer, the coating material having an electrically-conductive component together with at least one second component that is electrically insulating or poorly conductive. The installation further includes a main tank fitted with a unit for making a temporary connection with a circuit for dispensing the first component, and being raised to a high voltage when the connection unit not connected, and a feed circuit for continuously feeding the at least one second component. The main tank and the at least one second component feed circuit are carried by the moving portion of the robot and connected to feed the sprayer.

Dependent claims

An installation for spraying a multi-component coating material, said installation comprising:

a coating material comprising a first component that is electrically conductive and at least one second component that is electrically insulating or poorly conductive,
a main tank carried by a moving portion of a robot also carrying an electrostatic sprayer, said tank being provided with means for making a temporary connection with a circuit for dispensing said first component, and being raised to a high voltage when said connection means are not connected, and
at least one second component feed circuit for continuously feeding said second component, and
at least one mixer disposed downstream from a junction between a duct coming from said main tank and said second component feed circuit,
said main tank and said second component feed circuit being carried by said moving portion and being connected to feed said sprayer.
