Definitions

  • the present invention relates to a rotating coating product projector.
  • the present invention also relates to a coating product spraying method which uses such a rotary sprayer.
  • a rotary sprayer for spraying coating product comprises a spraying member rotating at high speed under the effect of rotary drive means, such as a compressed air turbine.
  • Such a spray member generally has the shape of a bowl with symmetry of revolution and it comprises at least one spray edge capable of forming a jet of coating product.
  • the rotary sprayer also comprises a fixed body housing the means for driving in rotation as well as means for supplying the spray member with coating product.
  • the jet of coating product sprayed by the edge of the rotating member has a generally conical shape which depends on parameters such as the speed of rotation of the bowl and the flow rate of coating product.
  • the rotary projectors of the prior art are generally equipped with several primary orifices formed in the body of the projector and arranged on a circle which is centered on the axis of symmetry of the bowl and which is located on the outer rim of the bowl.
  • the primary orifices are intended to emit jets of primary air together forming air for shaping the jet of product, this air for shaping being sometimes referred to as “skirt air”.
  • JP-A-8071455 describes a rotary sprayer provided with primary orifices intended to emit jets of primary air to conform the jet of product.
  • Each primary air jet is inclined with respect to the axis of rotation of the bowl in a primary direction having an axial component and an orthoradial or circumferential component.
  • the primary air jets thus generate a swirling flow of air around the outer periphery of the bowl and the jet of coating product.
  • This swirling air flow sometimes referred to as a "vortex" makes it possible, in particular by adjusting its flow rate, to conform the jet of product sprayed by the edge according to the desired application.
  • the rotating projector body shown in figure 6 of JP-A-8071455 is further provided with several secondary orifices also arranged on the outer periphery of the bowl and on the same circle as the primary orifices and offset from the latter.
  • Each jet of secondary air issuing from one of these secondary orifices is inclined relative to the axis of rotation in a secondary direction having an axial component and a radial component.
  • the secondary air jets are intended to obtain a uniform deposited paint film.
  • the direction of each jet of secondary air is therefore determined so as to prevent this jet of secondary air from striking the rear surface of the bowl.
  • an object coated by means of such a rotating projector presents impacts whose profiles are sometimes irregular and generally not very robust.
  • the robustness of an impact from a rotating projector of a coating product corresponds substantially to the regularity of a curve representing, as a function of a given parameter such as the skirt air flow, the width of the zone of median or upper deposited thickness, considered along a direction perpendicular to the direction of the relative movement between the rotary projector and the object to be coated.
  • the deposition efficiency of such a rotary projector is relatively limited.
  • the deposition efficiency also called transfer efficiency, is the ratio of the quantity of coating product deposited on the object to be coated to the quantity of coating product projected by means of the rotary projector.
  • JP-A-8084941 describes a rotary sprayer provided with primary orifices and secondary orifices to respectively emit primary air jets and secondary air jets.
  • the primary air jets and the secondary air jets are oriented in respective parallel or diverging directions, which produces marginal and low-volume overlaps between adjacent jets.
  • Such a rotary projector therefore also has the disadvantages mentioned above.
  • the present invention aims in particular to remedy these drawbacks by proposing a rotating coating product sprayer making it possible to obtain relatively high deposition yields as well as good robustness of the impacts of the coating product on the objects to be coated.
  • each primary direction and of each secondary direction induce the formation of combined jets each resulting from the intersection of at least one primary air jet and at least one associated secondary air jet, the intersection region being located upstream of the edge, and the ratio between the diameter of the edge and the diameter of the circle being between 0.65 and 1 and of preference equal to 0.95.
  • the subject of the present invention is a process for spraying coating product, using a rotary sprayer as described above, with a total air flow of between 100 NL/min and 1000 NL/min. , preferably between 300 NL/min and 800 NL/min and comprising from 25% to 75%, preferably 33%, of flow rate of the primary air jets and from 75% to 25%, preferably 67%, of flow rate secondary air jets.
  • the subject of the invention is a coating product spraying installation, which comprises at least one rotary sprayer as described above.

  • the bowl 1 is partially housed within a body 2.
  • the bowl 1 is shown in a spraying position where it is rotated at high speed around an axis X 1 by drive means, not shown.
  • the axis X 1 therefore constitutes the axis of rotation of the bowl 1.
  • the body 2 is fixed, that is to say it does not rotate around the axis X 1 .
  • the body 2 can be mounted on a support, not shown, such as a multi-axis robot arm.
  • a distributor 3 is secured to the upstream part of the bowl 1 to channel and distribute the coating product.
  • the speed of rotation of bowl 1 under load that is to say when it is spraying product, can be between 30,000 rpm and 70,000 rpm.
  • the bowl 1 has a symmetry of revolution around the axis X 1 .
  • the bowl 1 has a distribution surface 11 on which the coating product spreads, under the effect of centrifugal force, up to a spray edge 12 where it is micronized into fine droplets. All of the droplets form a jet of product, not shown, which leaves the bowl 1 and goes towards an object to be coated, not shown, on which it produces an impact.
  • the outer rear surface 13 of the bowl that is to say the surface which is not turned towards its axis of symmetry X 1 , is turned towards the body 2.
  • the body 2 has primary orifices 4 and secondary orifices 6.
  • the primary orifices 4 are arranged on a primary contour C 4 which surrounds the axis X 1 .
  • the secondary orifices 6 are arranged on a secondary contour C 6 which surrounds the axis X 1 .
  • the primary contour C 4 and the secondary contour C 6 are arranged in a common plane P 46 .
  • the common plane P 46 is perpendicular to the axis X 1 .
  • the plane P 46 is located in the downstream part of the body 2. Insofar as the body 2 has a symmetry of revolution around the axis X 1 , the common plane P 46 is materialized by a plane ring comprising the primary contours C 4 and secondary C 6 .
  • upstream and downstream refer to the direction of flow of the product from the base of the rotary projector P, located to the right of the figure 1 , to ridge 12, located to the left of the figure 1 .
  • the primary contour C 4 and the secondary contour C 6 each has a circular shape centered on the axis X 1 .
  • the primary contour C 4 and the contour C 6 coincide in a circle C which is therefore centered on the axis X 1 and on which the primary orifices 4 and the secondary orifices 6 are arranged.
  • the primary orifices 4 and the secondary orifices 6 belong to the body 2.
  • Edge 12 generally has the shape of a circle of diameter D 12 centered on axis X 1 . Serrations are made between the distribution surface 11 and the edge 12, some of which are shown in picture 2 with the reference 14, to improve the control of the size of the micronized droplets at the level of the edge 12.
  • the edge 12 is at an axial distance L 1 from the circle C, therefore from the primary contour C 4 or from the secondary contour ( C 6 ) is here 10 mm. In practice, the distance L 1 may be between 5 mm and 30 mm.
  • the distance L 1 represents the protrusion of the bowl 1 from the body 2.
  • the adjective “axial” qualifies a distance or, more generally, an entity which extends along the direction of the axis X 1 .
  • the diameter D of the circle C is here equal to 52.6 mm for a bowl 1 with a diameter equal to 50 mm. In practice, the diameter D can be between 50 mm and 77 mm for such a bowl.
  • the ratio between the diameter D 12 of the edge 12 and the diameter D of the circle C is equal to 0.95. According to the invention, this ratio must be between 0.65 and 1.

  • each primary direction X 4 has non-zero components along the three directions of a Cartesian coordinate system whose origin merges with the corresponding primary orifice 4, namely the direction of the axis X 1 , a radial direction and an orthoradial direction, that is to say circumferential or tangential.
  • Each primary direction X 4 and the bowl 1 are separate, so that each primary air jet J 4 can freely cross the region where the edge 12 is located.
  • the primary air jets J 4 do not hit the outer rear surface 13 of the bowl 1.
  • the primary jets J 4 together generate a swirling air flow, called "vortex air", which is capable to influence the shape of the spray of coating material.
  • vortex air a swirling air flow, called "vortex air"
  • Each primary direction X 4 is such that the corresponding primary air jet J 4 flows at a radial distance r 4 from edge 12 equal to 5 mm.
  • the distance r 4 is non-zero and less than 25 mm.
  • the distance r 4 depends in particular on the axial distance L 1 .

  • the number and distribution of the primary 4 and secondary 6 orifices is determined according to the precision sought for controlling the shape of the jet of product and the regularity desired for the impact surface. Thus, the more orifices 4 and 6 there are, the more regular the impact surface.

In practice, the body 2 may comprise between twenty and sixty primary orifices 4 and between twenty and sixty secondary orifices 6. Alternatively, primary orifices and secondary orifices in different numbers.

  • the meeting point 46 is located at an axial distance L 46 from the common plane P 46 of between 1 time and 2 times the largest dimension of the primary 4 or secondary 6 orifices. This largest dimension is taken in the common plane P 46 . In this case, it is either the diameter d 4 or the diameter d 6 , since the primary 4 and secondary 6 orifices have the same diameter. In practice, the axial distance L 46 between the meeting point 46 and the common plane P 46 is between 0.5 times and 30 times this largest dimension.
  • Such an axial distance L 46 makes it possible to achieve a relatively homogeneous addition of the flows of the primary air jet J 4 and of the secondary air jet J 6 , therefore to limit the irregularities of the combined jet J 46 at and downstream of the edge 12.
