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.

The invention concerns a rotary nozzle combination (P) for coating product comprising an atomizing bowl () and a rotor () adapted to rotate the bowl about a geometrical axis (X-X'), and means () for controlling the presence and/or proper mounting of the bowl () on the rotor (). The rotor () is spaced apart from a non-rotating part (P) and the control means comprise first means () enabling a force (F) to be applied on the bowl () tending to vary the thickness of an air-film of the pneumatic thrust bearing (P), as well as second means () for determining the air pressure in the bearing (P). The pressure of air in the thrust bearing (P) can be determined when the latter is normally supplied and compared with at least one reference value.

Rotary sprayer for spray coating material, an installation including such a sprayer, and a method of verifying the operation of such a sprayer

The bowl according to the invention is equipped with first magnetic coupling means adapted to cooperate with second complementary magnetic coupling means fixed on a non-rotary part of a sprayer, these first and second coupling means being adapted to exert an at least partially axial effort inducing the coupling in rotation of the bowl with a corresponding drive member. The radial width of an annular or truncated surface defined by the first coupling means is greater than the total radial width of the coupling means borne by the non-rotary part.

Spraying bowl, rotary sprayer incorporating such a bowl and spraying installation incorporating such a sprayer

The invention relates to a sprayer (), comprising a pneumatic turbine (), capable of rotating a bowl (), the turbine being connected to a pressurized gas supply line (), for driving said turbine and to a drive gas exhaust line (). The exhaust line () is equipped with an inner sleeve () which defines the exhaust gas flow volume (V), an annular gap (E) with a non-zero thickness being provided between the outer surface of the sleeve () and the inner surface of the line (). The structure is compatible with a temperature gradient between the optionally low-temperature exhaust gas flow volume (V) and the material () which forms the exhaust line (), the risk of condensation being thus limited.

A process and station for changing product in an installation for spraying coating product, by bringing a first reservoir towards a suitable area of a cleaning/filling station, separating a sub-assembly composed of the first reservoir and a first spray associated therewith, with respect to the robot, connecting with the robot a second, similar sub-assembly composed of a second reservoir and a second spray, adapted to be used for spraying coating product during cleaning and/or filling of the first reservoir and the first spray, and proceeding with cleaning and/or filling of the first reservoir and the first spray in the area.

Process and station for changing product in an installation for spraying coating product

The invention concerns a reservoir capable of being periodically cleaned and/or filled with a coating product equipped with a piston ( ) controlled in its movement by a control rod ( ). A module ( ) elastically deformable in compression (F) is incorporated in the kinematic linkage ( ) between the rod ( ) and the piston ( ) or between the rod ( ) and its actuating means, thereby providing elasticity for positioning the piston against the base of the reservoir, which enables a slight displacement of the piston rearwards when the cleaning product or fresh coating product is being injected.

Device for spraying a coating product comprising at least a sprayer and a piston reservoir

At least one spraying device ( ) and several supply lines ( ) for supplying the spraying device with a coating product, the lines being linked to a connecting assembly ( ). Each downstream end ( ) of a line is provided with a gate valve which can be controlled by an actuator ( ) which is itself controlled and which is positioned at the entrance to a product supply pipe ( ) for the spray device ( ). The actuator ( ) and the connecting assembly ( ) can be displaced in relation to each other (F -F ) in such a way that the actuator ( ) can be positioned selectively facing a downstream end ( ) of one of the supply lines ( ) and can manoeuvre the valve of the line. The ends ( ) of the lines are arranged in rows and columns and an assembly ( ) composed of the actuator and connected to the supply pipe ( ) is mobile parallel to a plane surface ( ) where these line ends ( ) open out.

A safety tripping system is controlled to prevent electrical arcing during use of high voltage apparatus, in particular an electrostatic coating product applicator. The safety tripping system is activated if at least one current parameter reaches a threshold. The threshold is varied as a function of the value of the high voltage in accordance with a predetermined law.
