Definitions

  • the invention relates to a coating product spray bowl, to a rotating projector including such a bowl, as well as to a method of cleaning such a projector.
  • Such a rinse box is complex to design and manufacture. Its use increases the coating product changeover time, as well as the operating cost of a coating product projection installation since this rinse box must be installed, supplied with cleaning product and maintained in a specific way.
  • US-B-6 569 258 proposes to clean guide air ejection ports by feeding a solvent through these ports themselves.
  • the cleaning is effective but this approach induces a high drying time of the multiple small supply channels of these air ejection ports. Indeed, at the end of the cleaning operation, these channels must be dried carefully, in order to ensure that no drop of cleaning product is projected onto an object being coated, which would harm the quality of the application.
  • the bowl of the first embodiment of US-A-2017/128969 comprises a shoulder provided at the outlet of a cleaning channel, which has the effect of directing a cleaning product, radially to the axis of rotation, towards an internal surface of a body of a projector in which this bowl is mounted, then towards the front of the projector.
  • the bowl of the second embodiment comprises an external radial surface that is cylindrical on the rear and frustoconical on the front. The coating product is guided, by the junction between these cylindrical and frustoconical surfaces, to take on a frustoconical shape and to flow forward.
  • the invention more particularly intends to remedy by proposing a new bowl for a rotating coating product projector which facilitates the cleaning of this projector, to the point that this cleaning can be carried out both efficiently and quickly, without the use of additional equipment, such as a rinsing box.
  • the invention relates to a coating product spray bowl intended to be integrated into a rotary coating product sprayer, this sprayer comprising a turbine for driving the bowl in rotation about an axis of rotation and a body which defines the axis of rotation and which comprises shaping air ejection orifices arranged in a crown, the bowl comprising a body centred on an axis and which defines an internal radial surface for distributing the coating product up to a spraying edge, as well as an external radial surface.
  • a deflector in one piece with the bowl, is arranged on the external radial surface of the bowl and returns, at least partially towards the crown of the body, a flow of cleaning product which flows along this external radial surface, towards the spray edge.
  • the deflector makes it possible to return cleaning product to the crown of the body into which the air ejection orifices open, which makes it possible to clean this crown of any deposits of coating product that have formed there, in a particularly simple, rapid and effective manner.
  • the front face of a headlight equipped with a bowl according to the invention can be cleaned effectively
  • the invention relates to a rotary coating product sprayer comprising a bowl rotating about an axis of rotation, a turbine for driving the bowl in rotation about the axis of rotation, a body which defines the axis of rotation and which comprises orifices for ejecting air for shaping a cloud of droplets of coating product discharged from the spraying edge of the bowl, these orifices being arranged on a crown of the body.
  • the bowl is as mentioned above.
  • Projector 2 a front part of which is shown in section in Figures 1 to 5 comprises a turbine 4 for driving a bowl 6 in rotation around an axis X8 defined by a body 8 of the projector 2.
  • the projector 2 can be of the electrostatic or non-electrostatic type.
  • the bowl 6 is supplied with coating product by an axial duct 10 centered on the axis X8 and which opens into a hub 62 of the bowl 6.
  • the bowl comprises a single-piece body 60 which defines an internal radial surface 61 and an external radial surface 65, relative to a central axis X6 of this bowl, which coincides with the axis X8 when the bowl 6 is mounted on the turbine 4.
  • the bowl 6 is equipped with a distributor 64 which makes it possible to return the coating product coming from the duct 10 towards the internal radial surface 61 on which this product is distributed and the downstream end of which constitutes a spray edge 63 of a cloud N of droplets of coating product, during operation of the projector 2.
  • the function of the surface 61 is to distribute the coating product coming from the duct 10, in a regular manner and with a decreasing thickness along the axis X8, approaching spray edge 63.
  • surface 65 also extends to edge 63.
  • upstream corresponds to a direction facing the source of the coating product or cleaning product, on the left of the Figures 1 to 7
  • downstream corresponds to an opposite direction, facing the spray edge 63, on the right of these figures.
  • the rotational securing between the rotor 42 of the turbine 4 and the bowl 6 can take place by magnetic attraction, in particular by means of a magnet 47 integrated into this rotor and a ferromagnetic ring 67 integrated into the bowl 6, at its external radial surface 65.
  • other means of rotational securing between the rotor 42 and the bowl 6 can be implemented, for example means of securing by screwing.
  • the body 8 is provided with skirt air ejection orifices 82 intended to guide or shape the cloud N of droplets of coating product leaving the edge 63 in the direction of an object to be coated, not shown.
  • skirt air ejection orifices 82 intended to guide or shape the cloud N of droplets of coating product leaving the edge 63 in the direction of an object to be coated, not shown.
  • the air jets exiting the orifices 82 are represented by the arrows F1.
  • the orifices 82 are regularly distributed around the axis X8, with an angular difference of between 2 and 15°.
  • the orifices 82 are supplied with pressurized air by conduits 84 provided in a part 86 of the body 2 which is most often called the “skirt”.
  • the orifices 82 open onto an annular surface of the body 2 which forms a crown 88 surrounding the axis X8 and the bowl 6 in the configuration mounted therein in the projector 2.
  • the crown 88 forms the front face of the body 8, that is to say its extreme face oriented towards the object to be coated during operation of the projector 2.
  • the crown 88 is generally perpendicular to the axis X8, that is to say forms in a plane radial to the axis X8 like that of the figures, an angle between 80 and 100° with the axis X8.
  • the problem that the present invention more particularly solves concerns the cleaning of this crown 88, particularly when changing the coating product.
  • a deflector 66 is provided on the external radial surface 65 of the bowl 6, this deflector 66 being arranged to return, that is to say direct, in the direction of the crown 88, at least part of a flow of cleaning product which circulates on the surface 65.
  • the deflector 66 is in one piece with the bowl 6 and can be produced by machining the external radial surface 65.
  • the deflector extends continuously over the entire periphery of the external radial surface 65, that is to say all around the body 60.
  • the deflector 66 forms an angular rupture zone of the external radial surface 65, that is to say a zone in which this surface changes orientation, abruptly, relative to the axis X6.
  • the portions of the external radial surface 65 located upstream and downstream of the deflector 66, in the direction of flow of the cleaning product towards the edge 63, are respectively noted 652 and 654.
  • the downstream portion 654 is arranged between the deflector 66 and the spray edge 63, along the axis X6.
  • the length of this portion 654, measured parallel to this surface in a plane radial to the axis X6, is noted d6. This length corresponds to the distance between the deflector 66 and the edge 63. This distance is measured between the downstream end of the deflector 66 and the edge 63. This distance is non-zero, preferably greater than or equal to 5 mm, more preferably greater than 10 mm.
  • Arranging the deflector 66 on the surface 65, more particularly in an intermediate zone close to the crown 88, makes it possible to use the liquid product intended for cleaning the surface 65 in order to also clean the annular surface formed by the crown 88.
  • the cleaning of the projector 2 comprises, in addition to the conventional steps of cleaning the internal radial surface 61 by injecting cleaning product via the conduit 10, a first step represented by the arrows F2 and consisting of directing the flow of cleaning product towards the upstream portion 652 of the external radial surface 65 of the bowl 6, while the latter is rotated by the turbine 4, around the axes X6 and X8 combined.
  • This first step is already known for certain projectors in which the external radial surface of the bowl is cleaned.
  • This method comprises an additional step during which the cleaning product is allowed to flow over the portion 652 up to the level of the deflector 66, to the point where it is then deflected or redirected towards the crown 88, which is represented by the arrows F4.
  • This second step is advantageously broken down into two sub-steps respectively represented in figures 2 And 3 .
  • the orifices 82 are not supplied with pressurized air. This allows the flow of cleaning product deflected by the deflector 66 to effectively clean the entire crown 88, including the portion 882 of this crown located radially outside the orifices 82.
  • the orifices 82 are supplied with pressurized air, to the point that jets of pressurized air emerge from these orifices 82, as represented by the arrow F1, which has the effect of pushing back the flow of cleaning product towards the downstream portion 654 of the surface 65, as represented by the arrow F6.
  • the deflector 66 is arranged, axially along the axis X8, downstream of the projection P88 of the surface 88 on this axis.
  • the deflector 66 is arranged downstream of the orifices 82, along the axis X8.
  • this can be arranged upstream of the orifices 82.
  • the deflector 86 can be aligned, along the axis X8, with the orifices 82.
  • the deflector 66 In radial section, the deflector 66 has a generally triangular shape, with two slightly concave surfaces, as visible in the figure 3 .
  • ⁇ 65 a straight line tangent to the surface 65 upstream of the deflector 66 in a plane radial to the axis X6, which is that of the figure 4 .
  • ⁇ 66 a straight line passing, in the same plane, through the base and the top of the surface 662, the base being the junction between the surface 65 and the deflector 66, on the upstream side of this deflector and the top being the external radial edge of the deflector 66.
  • the straight line ⁇ 66 represents the average orientation of the surface 662 in the plane of the figure 4 .
  • the lines ⁇ 65 and ⁇ 66 define, in the plane of the figure 3 , a dihedral D whose vertex angle is noted ⁇ .
  • This angle has a value of the order of 135°.
  • the dihedral D' formed by lines ⁇ 65 and ⁇ 66' can have an acute vertex angle ⁇ ', i.e. less than 90°.
  • the apex angle ⁇ or ⁇ ' of the dihedral D or D' defined between the upstream surface 662 of the deflector 6 and the external radial surface 65 upstream of this deflector has a value between 10 and 170°, preferably between 45 and 135°.
  • P66 the junction point between the lines ⁇ 65 and ⁇ 66 defined above.
  • P66' a point of intersection between the lines ⁇ 65 and ⁇ 66'.
  • the point P66 or P66' represents, in the plane of the figure 4 , a circle-shaped line from which the deflector 66 or 66' acts on the flow of the cleaning product.
  • the deflector 66 or 66' is considered to be upstream or downstream of the crown 88 depending on the position of this point P66 or P66' relative to the orthogonal projection P88 of the crown 88 on the axis X8.
  • this point P66 can be located, along the X8 axis, either upstream, like point P66A, or downstream, like point P66B, or at the same level, like point 66B that the orthogonal projection P88 of the crown 88 on this axis X8.
  • the deflector 66 is provided with channels 666 which each comprise a first branch 666A generally parallel to the portion 652 of the external radial surface 65 of the bowl 5 in the vicinity of the deflector 66 and a portion 666B connected to the portion 666A and directed towards the crown 88.
  • a flow of cleaning product as represented by arrow F2 at figure 6 can enter the various channel portions 666A and be redirected via the channel portions 666B to the crown 88 which can thus be effectively cleaned.
  • arrow F4 shows the path of the cleaning product inside the deflector 66 and its change of direction within a channel 666.
  • open channels 666 are formed by notches provided on the upstream surface 662 of the deflector 66, which is defined as in the first embodiment.
  • the 666 channels are advantageously regularly distributed around the X6 axis.
  • the number and distribution of the 666 channels of the sprayer of the figure 6 and the second embodiment can be chosen depending on the number and distribution of the outlet ports 82. This is however not obligatory.
  • the channels 666 can be characterized by their diameter which in practice is between 0.1 and 3 mm, preferably between 0.5 and 2 mm. If the channels are not of circular section, their largest transverse dimension is between 0.1 and 3 mm, preferably between 0.5 and 2 mm.
  • the channels 666 are also characterized by their angular orientation relative to the axis of rotation X8 and by the fact that they may or may not have an ortho-radial component relative to this axis. In other words, the channels 666 are divergent in the direction of the orifices 82 and can impart a vortex motion to the flow F2+F4 of cleaning product.
  • the deflector 66 may be formed by a strip of metal deposited on the surface 65 in the form of a weld or brazing bead.
  • the deflector may be locally interrupted to facilitate the flow of cleaning product to the surface portion 654, independent of the action of the shaping air.
  • the surface 65 can be supplied with cleaning product from inside the bowl, through the bowl.
  • the internal volume of the bowl is supplied with cleaning product, close to the deflector 64, and the body 60 is pierced with channels for circulation of the cleaning product towards the surface 65.
  • the cleaning product supply opens onto the external radial surface 65 of the bowl, enters the channels 666 of the deflector 66 and exits by centrifugal effect, as shown in figures 6 And 7 .
  • the supply of cleaning product opens directly into the channels 666 of the deflector 66. Furthermore, it is possible to use the same source of cleaning product to clean the surfaces 61 and 65, by means of two cleaning product supply lines, including the injector 10. As a variant, a restriction may be provided on the path of the cleaning product at the outlet of the injector, so as to limit the flow rate of this product which flows towards the internal radial surface 61, to the point that part of the flow is driven towards the external radial surface 65 which it thus cleans.
