Definitions

  • the present invention relates to a device for rotating a fluid circulating inside a nozzle.
  • the invention applies to the nozzle of a spray gun for a coating product, whether manual or automatic.
  • a spray gun comprises a spray head with a head ring and the nozzle, which is disposed coaxially inside the head.
  • the nozzle comprises a liquid passage channel configured to be selectively closed by a needle movable in translation inside the nozzle. The movement of the needle regulates the opening of the passage of the coating product. Depending on the position of the needle, the coating material will be expelled from the nozzle with more or less flow.
  • the spray head disposed around the nozzle comprises two horns each crossed by a compressed air ejection duct.
  • Each duct is configured so that air is expelled radially towards the spray of coating material.
  • the latter is then atomized into fine droplets under the impact of high-pressure air jets.
  • too high a compressed air pressure leads to the formation of a mist which reduces the transfer rate of the gun, that is to say the ratio between the quantity of product sprayed by the gun and the quantity of product actually deposited on the part to be coated (overspray).
  • EP-A-1 391 246 discloses a solution for improving atomization without increasing the compressed air pressure.
  • This solution consists in accommodating, inside the central duct of the nozzle, a device for fragmenting the liquid flow.
  • This device comprises a housing, a seat for positioning the housing and a spacer piece.
  • the housing and the seat delimit product passage holes, arranged to impose sudden changes of direction to the flow of coating product, which disturbs the flow.
  • the flow is thus destabilized upstream of the outlet orifice and the product is ejected from the nozzle in a turbulent form, ie in part defragmented.
  • the drawbacks of this device are its inability to expand the spray, its manufacturing cost (three separate parts) and its assembly difficulties. In addition, this device is difficult to clean.
  • the invention more particularly intends to remedy by proposing a device for setting in rotation which is easier to manufacture, less expensive, and easier to mount inside the nozzle.
  • US 3,123,306 discloses to figures 3 and 4 a gun with a mixer provided with a helical groove.
  • US 2013/0288195 A1 discloses a nozzle for sandblasting with detergents and EP 2 383 043 A2 discloses a spray gun for a two-component product, which relates to a very particular technical field which is that of sprayers equipped with a mixer.
  • the invention relates to a gun for spraying a coating product according to claim 1.
  • the invention also relates, as a variant, to a spray gun for a coating product according to claim 2.
  • this gun can comprise the characteristics of claim 3.
  • the groove (s) and / or the hole (s) of the device give the liquid circulating inside the nozzle a helical direction around a spray axis.
  • the rotation upstream of the outlet orifice of the nozzle results in a widening of the spray.
  • the flow is destabilized, even turbulent, which makes it easier to atomize.
  • the device makes it possible to obtain a distribution of drops of finer size, without increasing the pressure and / or the flow rate of the atomizing air jets.
  • the device makes it possible to obtain a gun with an atomization fineness identical to that of the guns of the prior art, but with less compressed air consumption, and therefore better efficiency.
  • the coating material can be a liquid comprising one or more components or a powder material. It can be paint, primer, varnish, etc.
  • the gun 1 comprises a body 10, a gripping handle 11 and an actuating trigger 12 articulated on the body 10.
  • the gun 1 comprises a spray head 14 and a head ring 16 disposed around the head 14.
  • the head 14 and the head ring 16 are centered on a spray axis X-X '.
  • the spray head 14 can advantageously be pivoted about the axis XX 'to direct the spray in a substantially horizontal plane, as in the configuration of figures 1 to 3 , or in a substantially vertical plane, as in the configuration of figure 6 to 8 .
  • the head 14 is hollow. It comprises two protuberances 14a and 14b, more commonly called horns or ears, which are arranged diametrically opposed to one another.
  • the horns 14a and 14b project parallel to the axis XX 'relative to the rest of the head 14. They each define two orifices 140 for ejection of compressed air.
  • the orifices 140 are shaped to guide air jets in the direction of the spray axis X-X '. More precisely, the air jets issuing from the orifices 140 have a direction which is substantially radial and centripetal with respect to the spray axis XX 'of the gun.
  • the adjective “substantially” is understood to mean that there is a difference of a few degrees between a direction strictly radial to the axis XX ′ and the direction of the air jets.
  • the pistol depicted in the figure 1 is therefore a gun of the pneumatic type, using air jets for the formation of the spray.
  • a nozzle 2 is disposed coaxially inside the head 14.
  • the nozzle 2 is a standard spray gun nozzle. It is about a part with geometry of revolution around the axis X-X '.
  • the nozzle 2 comprises two coaxial parts 2a and 2b, the part 2a being arranged inside the part 2b.
  • the nozzle 2 delimits a duct 6 of passage for the product. Conduit 6 is located inside part 2a.
  • the nozzle 2 is a “flat jet” type nozzle, that is to say that it is a nozzle whose footprint takes the form of a stretched ellipse.
  • the nozzle 2 can be a nozzle of the “round jet” type, that is to say a nozzle whose imprint takes the form of a disc or a ring.
  • the duct 6 is configured to be selectively closed by a needle 22 movable axially in translation inside the nozzle 2.
  • the movement of the needle 22 is controlled by the trigger 12.
  • a return spring (not shown) enables the return to be made. needle in the closed position when the operator releases the trigger 12.
  • An upstream direction is defined as a direction oriented in the direction opposite to the flow of liquid and a downstream direction as a direction oriented in the direction of the flow.
  • upstream is directed to the right, while downstream is directed to the left.
  • the duct 6 comprises, from upstream to downstream, a first section 60, cylindrical, a second section 62, frustoconical, the passage section of which decreases from upstream to downstream, a third section 64, also frustoconical and whose section decreases from upstream to downstream and an ejection channel 66, of constant passage section.
  • the “size” of a nozzle corresponds to the diameter of the last section of passage of the fluid before ejection, that is to say in the example to the diameter d66 of the ejection channel 66.
  • the size of a nozzle varies between 0.4 mm (4 gauge nozzle) and 2.7 mm (27 gauge nozzle).
  • a plane P is defined as the sealing plane of the needle 22 inside the nozzle 2.
  • the plane P is perpendicular to the spray axis X-X '. As visible at the figure 3 , the plane P is disposed at the interface between the section 64 and the channel 66.
  • the nozzle 2 according to the invention has the advantage that the position of the sealing plane P along the axis XX 'is standard, c' that is to say that the nozzle 2 is compatible with an existing commercial needle, such as the needle 22. This makes it possible to guarantee the flow rate of the nozzle 2 and to limit the presence of dead volumes, liable to retain product and cause drops to form after closing the nozzle 2.
  • buttons 18 and 20, visible at the bottom. figure 1 are designed to interrupt the spraying of product and the use of compressed air, respectively.
  • a removable device 30 is immobilized inside the conduit 6.
  • the device 30 is designed for standard gun nozzles. This is a rotating device fluid circulating inside the conduit 6. It comprises a body 32, the envelope surface S32 of which has a circular section.
  • the envelope surface is defined as a surface enveloping the body 32. It is then possible to imagine the surface S32 as the surface of the body 32 when the latter is enveloped in a film of zero thickness.
  • the envelope surface S32 is centered on an axis X32 which coincides with the axis XX 'when the device 30 is in place inside the duct 6.
  • the device 30 is a machined metal part.
  • the device 30 can be made of plastic and can be produced by other means, such as by molding or by means of a 3D printer.
  • the envelope surface S32 of the body comprises a cylindrical part S32a and a frustoconical part S32b disposed downstream of the cylindrical part S32a.
  • the diameter of the frustoconical part S32b of the surface S32 decreases going downstream.
  • the angle of convergence A32b of the frustoconical part S32b is between 10 and 350 °, in particular between 10 ° and 180 ° or between 180 ° and 350 °, preferably from 10 to 80 °, here equal to 60 °.
  • the duct 6 defines a housing for receiving the device 30 which is of a shape complementary to that of the body 32.
  • the diameter of the housing 60 is at all points identical to the diameter of the envelope surface S32.
  • This housing is formed by the sections 60 and 62 of the duct 6.
  • the diameter of the cylindrical part S32a of the casing surface of the body 32 is substantially identical to the diameter of the cylindrical section 60 of the duct 6 and the angle of convergence of the frustoconical part S32b of the surface S32 is identical to that of the section 62.
  • the device 30 is slid inside the duct 6. In the example, it is long enough to remain immobile in translation when handling the gun 1.
  • an additional stop device such as a tubular jacket mounted tightly or glued inside the duct 6, can be incorporated into the nozzle 2 to keep the device 30 stationary in translation.

  • the pitch is chosen lower when the fluid is viscous.
  • the rotational component of the speed vector at the output of the device 30 is approximately three times greater than the axial component.
  • the rotary effect is attenuated at the nozzle outlet for the small-caliber nozzles 2, in particular for the nozzles whose size is less than 0.9 mm, because the fluid undergoes a strong axial acceleration in the channel 66 due to reduction of the passage section.

  • the distance d1 between the the downstream end of the device 30 and the outlet orifice of the nozzle 2 is less than 10 mm, in particular equal to 6 mm. This ensures that the fluid retains its rotation until it exits nozzle 2.
  • the device 30 further comprises a gripping handle 36, which is of reduced diameter relative to the body 32.
  • the gripping handle 36 extends axially upstream with respect to the body 32. It advantageously allows manual removal. of the device 30 out of the nozzle 2 for cleaning and / or replacement.
  • the handle 36 advantageously extends over a length I36 at least equal to 5 mm. This minimum length makes it possible to manually push the device 30 as deeply as possible inside the duct 6, that is to say as close as possible to the outlet orifice of the nozzle 2.
  • the device 30 defines a through-bore 38 for the passage of the needle 22 for closing the nozzle 2.
  • the bore 38 extends axially through the handle 36 and the body 32.
  • the diameter d38 of the bore 38 is substantially equal to the diameter of the needle 22, so that the product does not pass inside the body 32.
  • the diameter of the bore 38 can be chosen greater than the diameter of the needle 22 , so that the product can pass inside the body 32. This has the advantage that the spray obtained is easier to spray and requires less energy (pneumatic for example) to be sprayed.
  • the gun 1 comprises a connection 40 for supplying coating product.
  • This connector 40 is oriented perpendicularly with respect to the spray axis XX 'and extends in particular downwards from the body 10 of the gun 1. It is intended to be connected to a product supply pipe (not shown ).
  • the path of the coating product from the connector 40 to the outlet of the nozzle 2 is represented by the arrows F1 at the bottom. figure 8 .
  • the figures 9 and 10 represent a second embodiment of the invention.
  • This second embodiment relates to a device 30 for rotating a fluid inside a nozzle 2, this device comprising a body 32 delimiting at least one helical hole 33 for the passage of all or part of the fluid.
  • at least one groove 34 is replaced by a helical duct, that is to say a hole 33 running through the body of the device 30 in a substantially helical direction.
  • a helical duct that is to say a hole 33 running through the body of the device 30 in a substantially helical direction.
  • Such a device can for example be manufactured using 3D printing.
  • the body 32 defines several helical holes 33 for the passage of all or part of the fluid.
  • the needle 22 and the device 30 are integral with one another.
  • the device 30 can be mounted tight around the needle 22 or crimped or glued to the needle 22.
  • the device 30 and the needle 22 can also be in one piece.
  • the nozzle 2 and the device 30 are linked in a non-removable manner.
  • the nozzle 2 and the device 30 can be two parts integral with one another or one and the same part, manufactured for example by 3D printing.
  • the groove or grooves 34 of the device 30 are cleaned by injection of solvent in place of the coating product.
  • the device 30 is mounted inside an automatic gun, which operates without manual action on the part of an operator and which is controlled remotely.
  • the section and / or the width of the grooves 34 may be different from one groove to another.
  • the section and / or the width of each groove can also vary according to its length.
  • the section of each groove 34 can be rectangular, triangular, elliptical, polygonal or a shape inspired by these solutions (3D printing).
  • the area of the section can also be variable. It is between 0.2 mm 2 to 8 mm 2 .
  • the duct 6 of the nozzle 2 comprises an ejection section which is flared and of rounded shape. This makes it possible to further expand the spray at the nozzle outlet by the Coanda effect.
  • This solution for widening the jet is particularly suitable for small caliber nozzles (less than 0.9 mm), for which the rotary effect conferred by the device 30 is less.
  • this type of nozzle provides a synergistic effect with the device 30 when the size is between 0.7 and 1.2 mm.
  • two devices for rotating in accordance with the invention that is to say comparable or identical to the device for setting rotation 30, are arranged in series one behind the other inside the duct 6.
  • the two devices have inverted pitches: each groove of a first device has a right-hand pitch, while each groove of the second device has a step to the left, or vice versa. This further destabilizes the fluid flow.
  • the two devices can be made in one piece.
  • the application device comprises two separate coating product supply conduits. It can be the same product or two different products to mix.
  • Each supply duct communicates with a corresponding groove 34 of the device 30, which then comprises at least two grooves.
  • the products circulating in the two separate conduits are mixed downstream from the device 30. A part of the fluid circulating inside the nozzle therefore therefore passes through a groove.
  • each groove of the device communicates with a separate coating product supply duct.
  • the number of product supply conduits can therefore be greater than 2.
