Definitions
- the invention relates to an electrostatic spraying sprayer for a coating product, and to a coating product spraying installation comprising such a sprayer.
- An electrostatic coating sprayer for coating product electrostatically charges a coating material and provides a good transfer rate of the coating product to the substrate to be coated.
- one end of a sprayer needle is raised to a high voltage of 10 to 200 kilo volts (kV), using a high voltage unit included in the sprayer.
- a persistent issue for an electrostatic coating sprayer is to limit the length, bulk and overall weight of the sprayer to improve handling.
- the choice of these parameters is dictated by the fact that a trigger and a rear part of the sprayer must be at the potential of the earth when, in order to load the coating product, one end of a needle of a sprayer is worn. at high voltage.
- electrostatic spraying sprayers known coating product such as that described in WO-A2-01 / 66261 are long, so difficult to handle.
- the air confined between the needle and its housing in the nozzle of the sprayer ionizes rapidly, which generates the production of ozone, which corrodes the surrounding materials and ends up causing holes and electrical rampages that can be dangerous. It is these drawbacks that the invention more particularly intends to remedy by proposing an electrostatic spraying spray of coating product that is easy to handle and whose safety is improved.
- the invention relates to an electrostatic spraying spray of a coating product
- a needle forming a movable valve of a valve for controlling the spraying of the coating product and positioned in a housing of a gun of the sprayer.
- housing defining a guide surface in axial translation of the needle along a longitudinal axis of the housing, the needle comprising a front end of shape adapted to abut against a seat to obstruct a coating product circulation duct, a rear portion which interacts with translational control means of the needle and a central portion between the front end and the rear part
- the sprayer also comprising a high voltage unit adapted to bring the front end to the high voltage of the needle.
- on the central part of the needle and inside the housing is provided at least a first relief capable of increasing the electric ramp distance along the central portion.
- the first machining operations in the needle make it possible to produce lighter, smaller, more manageable sprayers whose safety during their operation is increased, since these first machining operations make it possible to increase the distance of electrical ramping for the same length of the barrel and the needle and thus improve the resistance of the sprayer to these ramps.
- These reliefs make it possible to increase the electric creep distance, they also make it possible to produce sprayers of smaller dimensions than theoretically allow the intrinsic qualities of the materials used.
- such an electrostatic coating product sprayer may incorporate one or more of the following features, taken in any technically permissible combination:
- first reliefs are formed on the central portion of the needle and form recessed portions with respect to an envelope surface of the central portion of the needle;
- the first or first reliefs form a first helix recessed relative to the envelope surface of the central portion of the needle;
- the central portion comprises a portion of generally cylindrical shape and the or the first reliefs form a helix projecting from the cylindrical portion; - At least a second relief is formed in the housing, facing the first relief or reliefs;

- the first relief or reliefs form portions of reduced diameter with respect to the diameter of the envelope surface of the central part of the needle, whereas the diameter of the first reliefs is between 15% and 60% of the diameter of the the envelope surface of the needle, and the sum of the lengths, measured parallel to the longitudinal axis, over which each first relief extends is between 10% and 50% of the length, measured parallel to the longitudinal axis from the central part of the needle;
- the second reliefs form machined portions whose diameter is between 101% and 200% of the diameter of the guide surface of the needle, and the length, measured parallel to the longitudinal axis, on which each second relief is between 120% and 200% of the length over which each first relief extends;
- a volume left free by the first and second reliefs between the needle and its housing is filled with an electrically insulating product.
- the invention also relates to a coating product spraying installation comprising a power supply, a coating product tank and at least one electrostatic spraying spray of coating product as mentioned above.

- This installation 100 comprises an electrostatic spray gun 1 of coating product supplied with coating material, from a tank 20 of coating product, by a pipe 21.
- the gun 1 is also connected to a source of pressurized air by a pipe 31.
- the air from the source 30 is used to spray the coating product from the gun 1 to the object to be coated.
- a housing located in a gun 13 of the gun 1 in which a needle 3 slides, when an operator presses a trigger 6 or releases the trigger 6 of the gun 1.
- the housing 4 defines a translational guide surface S4 of the needle 3 along a longitudinal axis Y4 of the housing 4.
- the surface S4 is cylindrical with a circular base.
- the needle 3 has a generally cylindrical shape except at a front end 3a, positioned near a spray outlet S of the coating product, which forms a triangular tip.
- the needle 3 also comprises a rear portion 3c connected to the trigger 6 and a central portion 3b between the front end 3a and the rear portion 3c. It is through the link between the rear part 3c and the trigger 6 that the movement of the needle 3 is controlled.
- the needle 3 consists of three different materials in three different parts.
- the end 3a of the needle 3, intended to be raised to a high potential, is made of a first electrically conductive material of high Shore hardness, in particular greater than or equal to 55 HRC.
- the end 3a is represented by an area comprising FIGS. 1, 2 and 3.
- the central part 3b of the needle is made of a second insulating material, while the rear part 3c of the needle 3, corresponding to the part of the needle 3 hatched with Figures 1, 2 and 3 is made of an electrically conductive material and hard.

- a first seal 41 is disposed in the groove 4a, around the needle 3 with which it is in sliding contact.
- This seal 41 ensures a seal of the housing 4, vis-à-vis elements external to the gun 1 and vis-à-vis the coating product which, during the spraying coating product, leads through the conduit 2 at the level of the end 3a of the needle 3.
- the housing 4 comprises a second groove 4b located on the side of the trigger 6 and the rear portion 3c, opposite the first groove 4a.
- a second seal 42 is disposed in the groove 4b, around the needle 3 with which it is in sliding contact.
- This second seal 4b provides a good seal of the housing 4 vis-à-vis the intrusion of bodies or products from the outside such as dust, solvents, paint residue.
- the materials of the joints 41 and 42 are adapted to the (x) material (s) constituting the end 3a and the rear portion 3c to ensure a tight support of the needle 3 against these seals.
- This duct 5 comprises a first section 5a and a second section 5b between which is a valve 7 for controlling the flow of air.
- the second section 5b opens near the end 3a of the needle 3 at the outlet S.
- the air valve 7 comprises a valve 7a adapted to bear against a seat 7b, of corresponding shape, under the effect of a return force R exerted by a spring 50 held in position by a plug 51 forming a point fixed support for this spring 50.
- the valve 7a is integral in translation with the needle 3.
- the spring 50 keeps the needle 3 in a position preventing the circulation of the coating product, the conduit 2 to the output S, when no force is exerted on the trigger 6 of the gun 1.
- the end 3a of the needle 3 is shaped to bear against a seat 33 of corresponding shape under the effect of the return force R.
- the needle 3 and the seat 33 form together a valve 63 for controlling the flow of coating product.
- the needle 3 forms the movable valve of the valve 63.
- the trigger 6 is articulated on a body 15 of the pistol about an axis X6 perpendicular to the axis Y4. It allows the opening and closing of the air valve 7, as well as that the movements of the needle 3 parallel to the axis Y4. More specifically, the trigger 6 is in abutment against the valve 7a and, when it undergoes a force opposite to the return force R, to exert on the valve 7a a force opposite to the return force R to shift axially, along the axis Y4, the valve 7a with respect to its seat 7b. This makes it possible to set the needle 3 in motion parallel to the axis Y4.
- the spring 50 pushes the valve 7b and the needle 3 towards, respectively, the interruption position of the air flow duct 5 and the coating product duct 2.
- the trigger 6 allows thus to control the circulation of coating product and pressurized air in the circulation ducts 2 and 5.
- the gun 1 is also connected to a high voltage generator 10, by an electric cable 1 1 which supplies power to a high voltage unit 12, disposed in the barrel 13 of the gun 1.
- the generator 10 is itself supplied with power from the mains by means of a cable 17.
- the high voltage unit 12 makes it possible to bring to a high voltage, that is to say to a potential whose absolute value is between 10 kV and 200 kV, the end 3a of the needle 3 to which it is electrically connected by means not shown.
- first machining 8 are regularly formed on the outer contour of the central portion 3b of the needle 3, opposite the housing 4, along the needle 3, first machining 8 are regularly formed.
- the central portion 3b has a cylindrical envelope surface S3b with a circular base of diameter D3.
- the first machinations 8 form recessed portions, with respect to the envelope surface S3b of the needle 3, which have a diameter D8 less than the diameter D3 of the envelope surface S3b.
- the diameter D8 of the recessed portions formed by the first machining operations 8 is preferably between 15% and 60%, of the diameter D3 of the envelope surface S3b.
- U8 is a length, measured parallel to the axis Y4, on which each first machining 8 extends.
- second machining operations 9 are arranged opposite the first machining operations 8.
- the second machining operations 9 form recessed portions with respect to the guide surface S4 of the needle 3.
- the diameter D9 of the parts hollow formed by the second machining 9 is greater than the diameter D4 of the surface S4 for receiving and guiding the needle 3.
- the diameter D9 of the recessed portions is preferably between 101% and 200% of the diameter D4 of the surface S4.
- U9 is a length, measured parallel to the axis Y4, on which each second machining 9 extends.
- Each first machining 8 extends parallel to the axis Y4 along the length U8.
- the sum of the lengths U8 over which each first machining 8 extends is between 10% and 50% of the length U3b of the central part 3b of the needle 3, measured parallel to the axis Y4.
- Each second machining 9 extends over a length U9 greater than the length
- the length U9 is between 120% and 200% of the length U8.
- the first machining operations 8 and the second machining operations 9 make it possible to increase the electrical ramping distance, compared to a configuration where the needle and the housing do not include machining, and thus to prevent the trigger 6 or a part 16 rear of the gun 1 is at a potential different from that of the earth when the end 3a of the needle 3 is raised to high voltage.
- the second machining 9 are formed on a length U9 greater than the length U8 on which are formed the first machining 8, regardless of the position of the needle 3 in the housing 4, the electrical creep distance does not change not.
- a volume V1 left free between the needle 3 and its housing 4 is filled with an electrically insulating product.
- This product may be, for example, dielectric grease. It allows by its properties, to increase the length of the ramping path between the front end 3a and the rear part 3c and, thus, to make a gun 13 shorter than would allow the intrinsic qualities of the materials used for the barrel 13 and the needle 3.
- this electrically insulating product prevents any formation of ozone. Indeed, in the absence of this insulating product, the air confined between the needle 3 and its housing 4 in the barrel 13 ionizes rapidly, which generates ozone. Gold is a harmful gas for health and corrodes the components of the needle 3 and its housing 4, which eventually cause electrical rampages that can reach the hand of the operator in the case of a pistol 1 manual.
