Definitions

  • the present invention relates to a rotating electrostatic sprayer of coating product which comprises a spray bowl, a body and a turbine mounted in this body and configured to drive the bowl in rotation about an axis defined by the body.
  • the electrodes, a body of the projector and a shaping air ejection skirt can be protected by means of a cover, in order to prevent them from getting dirty.
  • the arrangement of the electrodes with a divergent configuration towards the front of the headlamp requires the cover to be relatively bulky, which makes the headlamp bulky, to the point that its use must, in practice, be limited to the external surfaces of an object, such as than a vehicle body.
  • the invention more particularly intends to remedy by proposing a new electrostatic sprayer of coating product which can be used to coat interior surfaces and which can be easily and quickly cleaned, when necessary.
  • each resistor extends axially outside the ring and is equipped, at its end opposite the electrode which it supplies, with a first plug for electrical connection to a second plug of geometry corresponding provided on the body of the projector, with a movement parallel to the axis of rotation, while the ring is configured to be mounted and connected to the body, or disassembled or disconnected from the body, being equipped with electrodes and resistors.
  • the ring fitted with the various electrodes and resistors which project axially outside the ring, towards the rear of the sprayer, can be easily removed from the sprayer when this ring has a level of dirt which requires a cleaning operation, which can be carried out outside the sprayer, in particular during a subsequent coating phase, that is to say in masked time with respect to the periods of use of the sprayer.
  • the assembly/disassembly of the ring takes little time, which makes it possible to envisage a rapid exchange of a ring equipped with dirty electrodes with a ring equipped with clean electrodes, without delaying a production line implementing the projector of the invention.
  • the invention relates to an installation for the electrostatic spraying of coating product on objects to be coated, which comprises at least one projector as mentioned above.
  • Installation 2 represented very schematically in figure 1 serves to cover objects O which, in the example of the figures, are electrical cabinet boxes or air conditioning systems which have openings O1 and O2 and which each define an interior volume VO.
  • objects O are moved by a conveyor 4, in a conveying direction represented by an axis X4 on the figure 1 .
  • the conveyor 4 comprises several nacelles 42 which each make it possible to support an object O to be coated and to move it along the axis X4.
  • the installation 2 also comprises an electrostatic and rotating projector 10 which is represented, on the figure 1 on a larger scale than the other components of the installation 2.
  • This projector 10 is mounted on the wrist 62 of a multi-axis robot 6 which also belongs to the installation 2. It is supplied with coating product to be sprayed, in high voltage and pressurized air through conduits not visible on the figure 1 And 2 and which circulate through the wrist 62.
  • the projector 10 makes it possible in particular to apply a coating product to the internal surfaces of an object O supported by the conveyor 4, which delimit its internal volume VO.
  • the projector 10 is sufficiently compact to engage in the interior volume VO through one of the openings O1 or 02.
  • the projector 10 comprises a body 102 on which is mounted a turbine 104 for driving a bowl 106 in rotation, around an axis of rotation A100 defined by the body 102.
  • the bowl 106 is secured to the rotor of the turbine 104 by any appropriate means, in particular by screwing or by magnetic assembly.
  • the body 102 is mounted on a plate 108 which constitutes the distal face of a bent part 110 of the projector 10, which makes it possible to offset the axis A100 with respect to a central axis A62 of the wrist 62.
  • a cable 112 for supplying the projector 10 with high voltage, for example a voltage between -40 and -100 kV, in particular equal to -60kV.
  • An injector 120 is placed in the center of the turbine 104 and makes it possible to inject liquid coating product into the bowl 106.
  • the connection between the supply pipe 116 and the injector 120 is not visible on the picture 3 because it takes place in a plane different from that of this figure.
  • the body 102 is formed of an inner part 1022 and an outer part 1024 which are both assembled on the plate 108, in addition to being assembled together.
  • the front of the projector 100 is defined as the side of this projector facing the objects O to be coated when the projector 10 is operating.
  • Bowl 106 is mounted on the front of projector 106.
  • the front of projector 10 faces right on the figures 1 to 5 .
  • the rear of the projector 10 is defined as the side opposite the front, the rear of the projector 10 being oriented towards the left on the figures 1 to 5 , moving away from the objects O relative to the bowl 106.
  • the projector 10 includes a skirt 124 intended to eject air around the bowl 106 when the projector 10 operates to coat objects O.
  • the skirt is a sub-assembly of the projector 10 mounted around the body 102 and the turbine 104 and which defines air circulation channels up to the vicinity of the bowl 106. More specifically, the body 102 is provided with an external thread 1021 and the skirt 124 is provided with an internal thread 1241 by which the skirt 124 is screwed around the body 102.
  • the skirt 124 comprises a one-piece inner part 1242 and an outer part 1244 which is two-part and which comprises a front outer part 1244A and a rear outer part 1244B, the front outer part 1244A being located further to the front of the headlamp 10 than the part outer rear 1244B, that is to say closer to the bowl 106.
  • pressurized air circulation ducts 1246 are formed in the internal part 1242 of the skirt 124.
  • Other air circulation ducts 1247 are formed in the external part 1244.
  • the ducts 1246 and 1247 open onto a front face 1248 of the skirt 124, in the form of orifices 1249 distributed around the axis A100 and the bowl 106.
  • the various ducts 1246 and 1247 are supplied with air under pressure from the pipe 118, the connection between these ducts and this pipe taking place on a plane different from that of the picture 3 .
  • Electrodes 140 are mounted on an annular ring 160 which is in the form of a closed ring, with a circular base in the example.
  • each electrode 140 comprises a body 142 and a needle 144, the tip of which is noted 146, which is turned towards the front of the headlight 10.
  • each electrode 140 is housed in a sleeve 170 in which a resistor 180 is also received, through which the electrode 140 is supplied with high voltage from the cable 112.
  • a resistor 180 is also received, through which the electrode 140 is supplied with high voltage from the cable 112.
  • Note 184 a first front end of each resistor 180 by which this resistor bears against the body 142 of the electrode which it supplies.
  • a male plug 113 disposed at the end of the cable 112 is plugged into a female plug 190 of corresponding shape, which is connected, by a conductive bar 192, to one of sixteen blind housings 194 in each of which is disposed a 196 female plug.
  • the parts 1022 and 1024 of the body 102 are made of an electrically insulating material, such as PTFE, and the internal surface of each of the blind housings 194 is coated with a conductive powder, for example a carbon-based powder.
  • a conductive powder for example a carbon-based powder.
  • the conductive layers of the different blind housings 194 are electrically connected to each other by conductive elements 198 embedded in the body 102.
  • each of the female plugs 196 is brought to the high voltage, from the high voltage cable 112 .
  • the body 102 is equipped with sixteen sheaths 200 each aligned with a blind housing 194 along their longitudinal axis A200 which is parallel to the axis A100 and radially offset from the latter.
  • the sleeves are each arranged in front of a blind housing 194.
  • the sleeves 200 are each located in the extension of a blind housing 194, along an axis A200 parallel to the axis A100, and a plug female 196 is aligned, along an axis A200, with each of the sleeves 200, on the rear side of this sleeve.
  • Each sleeve 170 is screwed into the ring 160 by means of a thread 172 provided near a first front end 174 of each sleeve.
  • the ring 160 is provided with sixteen threaded holes 162 allowing the front ends 174 of the sleeves 170 to be screwed.
  • each sleeve 170 is mounted and firmly held in position on the ring 160, all the sleeves 170 and the resistors 180 that they contain extending on the same side of the ring 160, essentially outside the latter, towards the rear of the headlight 10, in the direction of the blind housings 194.
  • An O-ring 202 is mounted around the body 142 of an electrode 140, inside the first front end 174 of the corresponding sleeve 170, while another O-ring 204 is mounted between the first front end 174 of the sleeve 170 and ring 160. Gaskets 202 and 204 seal between the interior volume of a sleeve 170 and the exterior.
  • each tip 146 is arranged in a bowl 166 made for this purpose on the front face 168 of the ring 160 facing the front of the projector 10.
  • Each tip 146 protrudes from the bottom of a bowl 166, forward .
  • the spikes 146 do not protrude forward from the front face 168, which limits the risk of injury when handling the ring 160, in particular when wiping the surface 168.
  • the ring 160 also comprises a latching member formed by an elastically deformable tab or strip 169 which extends over the entire periphery of the ring 160 and which is provided to cooperate with a complementary latching relief 1029 provided on the outside of the body 102, with a geometry corresponding to that of the lug 169. This makes it possible to immobilize axially and to center radially to the axis A100 the ring 160 on the body 102.
  • each resistance 180 is placed at the level of the first front end 174 of the sleeve which receives it, while the second rear end 186 of this resistance is placed at the level of the second rear end 176 of the same sleeve.
  • An electrical connector 206 is mounted in each sleeve 170, at its rear end 176, and it makes it possible to accommodate a male plug 208 of the “banana plug” type with elastically deformable outer blades.
  • the second end 186 of each resistor 180 is thus equipped, through a connector 206, with a male plug 208 to which it is connected. All the male plugs 208 extend axially on the same side of the ring 140, towards the rear of the projector 10, and parallel to each other.
  • each male plug 208 allows it to cooperate by wedging with a female plug 196 placed in one of the blind housings 194, when the sleeve 170 to which it is integral is completely inserted into the corresponding sheath 200, which is aligned with this blind housing 194.
  • each of the electrodes 140 is supplied with high voltage through a conductive element 198, a female plug 196, a male plug 208, an electrical connector 206 and a resistor 180.
  • a flow of ions can be emitted by each of the tips 146 to charge the coating product leaving the edge 1062 of the bowl 106, when this bowl is driven in rotation by the turbine 104 and when this bowl is supplied with coating product through pipe 116.
  • the product leaving bowl 106 is thus electrostatically charged by a so-called “external” or “Corona” charging phenomenon.
  • the ring 160 tends to get dirty, especially at the level of the cups 166 or the front face 168, it is possible to remove the ring by a simple pulling force parallel to the axis A100, as represented by the arrow F1 at there picture 2 .
  • This effort F1 results in an axial movement of the ring 160, of the sixteen electrodes 140, of the sixteen sleeves 170 and of the sixteen male plugs 208 which are integral with this ring, which has the effect of extracting the first plugs, formed by the male plugs 208 and which are movable with the ring 160, second plugs formed by the female plugs 196, which are fixed with the body 102.
  • This displacement of the first ring 160, of the electrodes 140, of the sleeves 170 and of the resistors 180 takes place without it being necessary to dismantle the bowl 106 or the skirt 124 which remain in place on the body 102.
  • the inside diameter of the ring 160 is strictly greater than the outer diameter of the bowl 106 and the outer diameter of the skirt 124 over its axial length between the bowl 106 and the ring 160 mounted on the body 102.
  • the projector 10 is functional again and can be used to cover the objects O, whereas the first ring, which has been removed, can be cleaned in masked time.
  • the interruption of the operation of the installation 2 is therefore limited to the time necessary for the disassembly and disconnection of the first ring 160 with respect to the plugs 196 and the assembly of the second ring 160 and its connection to the plugs 196, these operations taking place by simple axial translation, in the direction of the arrows F1 and F2.
  • the separation movement of the ring 160 and the body 102 takes place against the latching force exerted by the elements 169 and 1029.
  • This latching force can be overcome by means of a sufficiently intense force F1.
  • the ring 160 is provided with a peripheral groove 165 in which the jaws of a tool (not shown) can be engaged, which makes it possible to radially tighten the ring 160 then to exert the force of traction in the direction of the arrow F1.
  • a tool can, for example, have three jaws, distributed radially around the axis A100 and which are just engaged and clamped in the peripheral groove 165 by means of a ring which tightens these jaws.
  • the assembly and connection effort of the ring 160, in the direction of the arrow F2, is a pushing force exerted on the front face 168.
  • the cooperation of the first and second plugs 208 and 196 makes it possible to center the ring 160 and the electrodes 140 that it carries relative to the body 102, to the bowl 106 and to the axis A100 simply by placing the ring in place. 160 around body 102.
  • the electrodes 140, the sleeves 170, the plugs 196 and 208 and the sheaths 200 are identical.
  • the mode of assembly and disassembly of the ring 160 equipped with the electrodes 140 and the resistors 180 on the body 102 which takes place according to two axial translation movements in the direction of the arrows F1 and F2, makes it possible to envisage an assembly and a automatic dismantling of the ring 160 on the body 102, by means of a robot.

  • Such a polarization of the air ejected by the slot 232 can be envisaged permanently or only in the event of a drift in the high voltage value delivered at the level of the electrodes 140.
  • the annular slot 232 and the air that comes out of it when the projector is in operation make it easier to clean the projector 10 within a flushing box.
  • it is customary to bring part of a projector into contact with an edge of the flushing box, with the interposition of a seal.
  • It is also customary to provide, in the rinsing box, an internal air jet and/or a device for scraping the external surface of the headlamp.
  • the flow of air represented by the arrow F4 makes it possible to dispense with this seal, internal air jet and/or scraping device because it permanently cleans the front part of the headlight, including when the latter is engaged in the rinse box. This gives more freedom in the design of the outer shape of the body 102 and of the skirt 124.
  • the air gap which comes out of the slot 232 through its outlet 234, as represented by the arrows F4, makes it possible to confine spills of cleaner and coating material to the inside of the flush box.

More specifically, the tips 146 of the electrodes 140 and the opening of the slot 232 towards the outside are farther from the edge 1062 and the orifices 1249 than the front outer part 1244A of the skirt 124. of the axis A100, the annular slot 232 is arranged in the vicinity of the tips 146, which are also offset rearward with respect to the orifices 1249.

  • the disassembly of the skirt takes place by unscrewing the ring 160 relative to the body 102, by disengaging the thread 1241 from the thread 1021. It is then possible to screw onto the thread 1021 the body of a tool, not shown, which is provided with elastic tabs which extend rear of the projector 10, beyond a surface S161 of the ring which is radial to the axis A100 and facing the rear of the projector. These lugs deform elastically to pass radially through the center of the ring 160, between this ring and the body 102, inside the volume V102, when the tool is mounted on the body 102.
  • Free ends of the elastic lugs have harpoon tips which, when the legs return to their unconstrained configuration, engage behind surface S161.
  • THE harpoon tips are distributed around the body 102, therefore able to exert on the surface S161 an axial force in the direction of the arrow F1, this force being distributed around the axis A100 due to the multiplicity of the legs in question .
  • This force is exerted when, after having engaged the harpoon tips of the legs of the tool behind the surface S161, the tool is unscrewed relative to the body 102.

  • the portion of the front face 168 of the ring 160 exposed to the return of paint between two points 146 is relatively small, which limits the area of the surfaces of the ring 160 to be cleaned.

  • the first plugs 208 secured to the ring 160 are female plugs, while the second plugs 196 secured to the body 102 are male plugs.
