A system for analysing drops capable of being ejected by a coating product applicator, includes a light source configured to illuminate a drop ejection zone, designated observation zone; a first image acquisition device configured to acquire an image of the observation zone; and an image analyser configured to determine, from the image of the observation zone, the presence of drops at a given distance from the applicator, the size of the drops and the absence of satellite; the light source and the first image acquisition device being situated on a same side of the observation zone.

System for analysing drops and coating installation comprising such a system

A method for applying a coating product using the drop on demand technology, wherein the coating product is deposited by a robot applicator including a controller and at least one nozzle with sequential opening, commanded by the controller, the method including moving the nozzle of the robot applicator between a starting point and an arrival point, the projections of which, along the ejection axis of the nozzle, on the surface to be coated, define first and second reference points respectively belonging to two edges of the surface to be coated, in order to deposit a series of drops between the two edges, the spacing between the respective centers of two successive drops being adjusted by the controller as a function of the length of the journey between the two reference points and such that the last drop is deposited in a centered manner on the second reference point.

Method for applying a coating product according to the drop on demand technology and robot applicator for carrying out the method

The invention relates to a sprayer, comprising an air guiding element and means for fastening the air guiding element on a fixed member of the sprayer. The fastening means comprise at least one magnetic attraction means mounted on a first component from among the air guiding element and the fixed member and at least one part made from a ferromagnetic material, which is intended to cooperate with the magnetic attraction means and which is mounted on or formed by the other component from among the air guiding element and the fixed element.

Coating sprayer, method for assembling and disassembling

A method of applying a coating product on a surface of a part, this method being carried out using an applicator including at least one row of nozzles, among which at least the first nozzle in the row includes a valve, the method including moving the applicator in a first direction to apply a first layer of coating product, and moving the applicator in a second direction substantially parallel to the first direction to apply a second layer of coating product adjacent to the first layer, comprising measuring at least one application distance of the first nozzle from a point in front of the first nozzle on a path of the applicator, and based on the measured application distance, opening or closing the valve.

Applicator of coating product, multiaxis robot comprising such an applicator and application method of a coating product

This method allows a coating product to be applied to a component () being moved by a conveyor (), along which conveyor at least one spray () is arranged. It comprises automated steps involving determining, within a fixed frame of reference (X, Y, Z), the coordinates of the points (A, B, C, A, B, C) of one or more lines (L, L) of the exterior profile of the component which are distributed along the length of the component, in assigning to each spray the points of each exterior profile line that lie within its field of spraying, in identifying, from among the points assigned to each spray, the point (A, A; B, B) closest to the spray for each exterior profile line, in determining, for each spray, a line (L, L) to follow that passes through all the points (A, A, B, B) closest to the spray as identified in step c), and in establishing a reference path for each spray according to the points on the line (L, L) to follow so that the application distance of each spray is adjusted automatically and independently according to the exterior profile of the component.

Method for applying a coating product to a component being moved by a conveyor, and coating product application installation

A station for reloading a sprayer is disclosed that includes a tank coupled to at least one coating material circuit by a coupler, a docking unit that is adapted to receive a sprayer; and at least one accumulator having a volume that is greater than or equal to the volume of the tank. Each accumulator is connected to at least one circuit by the coupler. The station also includes a mechanism for pressurizing the accumulator. The accumulator is connected to the docking unit which is, in turn, connected to the tank.

Station and a method for reloading a mobile sprayer with coating material

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.
