A fluid spraying facility including a fluid circulation pipe and a scraper that can circulate in the pipe in order to push back the fluid present in the pipe as it moves forward, the pipe and the scraper each having a circular section, the pipe having an inner diameter, the scraper having an outer diameter, the outer diameter having a first value. A difference between the inner diameter of the pipe and the first outer diameter value of the scraper is greater than or equal to 100 micrometers, preferably greater than or equal to 200 micrometers.

Fluid spraying facility and method for moving an associated fluid

An installation including an atomizer configured to atomize a fluid, a robot and a first station, the robot being configured to move the atomizer in a predetermined reference frame between at least a first position and a second position, the atomizer being configured to atomize the fluid when the atomizer is in the first position, a distance being defined between the atomizer and the first station, the distance when the atomizer is in the second position being strictly less than the distance when the atomizer is in the first position. The first station includes at least one sensor configured to measure at least one value of a parameter of the atomizer when the atomizer is in the second position.

Installation for an atomizer to atomize a fluid

An atomizer having an atomizer head configured to atomize a first fluid. The atomizer includes, in addition, a measurement module including at least one sensor configured to measure the values of at least one parameter of the atomizer, an electronic control module configured to receive the measured values, and a power supply configured to electrically supply the control module with a power supply voltage.

A method applying a bead of a coating product to a surface by a print head equipped with nozzles, each centered on a central axis, the coating product application moves the print head and the surface relative to each other, by moving the print head along a fixed trajectory relative to the surface without rotating the print head about an axis parallel to the central axes of the nozzles. The method includes selecting certain nozzles for a point of the trajectory based on the trajectory direction at this point, and activating the selected nozzles at this point. The selected nozzles are arranged in a line, or form part of a nozzle group delimited by a line, whose regression line coincides with a line as close as possible to a line perpendicular to the trajectory direction from among lines that can be defined with nozzles of the print head.

This method for painting a surface (S) of a component () with a pattern includes at least the following steps consisting in applying a first coating product on at least a portion of the surface, automatically applying at least one portion of a mask () on a portion (Z) of the surface, applying a second coating product and on the surface and removing the mask (). Preferably, the mask () is at least partially automatically applied in the form of at least one layer () of non-atomized fluid, the layer being obtained by moving (A) an applicator () delivering the non-atomized fluid along the portion (Z) of the surface (S) where the mask () is to be applied.

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.

A spray nozzle for electrostatic spraying of a coating product including a needle forming a mobile shutter of a valve for controlling the spraying, which is positioned in a recess of a barrel of the nozzle. The recess defines a surface for guiding the axial translation of the needle along a longitudinal axis of the recess. The needle includes a front shaped for abutting a seat to obstruct a duct for flow of the coating product, a rear portion which interacts with means for controlling the translation of the needle and a central portion comprised between the front end and the rear portion, while a high-voltage unit included in the nozzle is capable of applying a high-voltage to the front end of the needle. A raised portion provided on the central portion of the needle, inside the recess, can increase the electric creepage distance along the central portion.

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

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.

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.
