Definitions

  • the invention relates to a bell cup for a rotary atomizer for coating workpieces, in particular for powder coating according to the preamble of claim 1, and to a matching rotary atomizer according to the preamble of claim 7.
  • a powder atomizer for the series coating of workpieces in which the atomization of the powder used as a coating agent is carried out by a bell cup, which is mounted on a rotatably mounted in the powder atomizer bell cup shaft and rotates at a high speed.
  • a gap channel which widens conically in the axial direction to the free end of the bell cup, wherein in the gap channel during the coating operation, a powder-air mixture flows due to the rotational forces to the outer edge of the bell cup, where it exits is atomized into the open air.
  • the feeding of the powder used as a coating agent takes place here by a centrally arranged in the bell-plate coating agent channel, wherein the central coating agent channel is surrounded by a coaxial shell detergent detergent channel, which allows a purging of the gap plate located in the bell cup with purging air during processing pauses.
  • a disadvantage of this known Pulverzerstäuber is the fact that a flushing of the bell cup is possible only during processing breaks when no powder-air mixture is conveyed into the gap channel.
  • bell plates or powder sprayers are made DE 39 12 700 C1 .
  • DE 35 28 084 A1 such as EP 0 283 918 A2 known.
  • these bell cups also have the disadvantage that no rinsing of the bell cup is possible during the coating operation.
  • the invention is therefore based on the object to improve the known Pulverzerstäuber described above.
  • the invention encompasses the general technical teaching of providing a separate detergent channel in the bell cup in addition to the coating agent channel, so that the rinse agent can be conveyed independently of the coating agent, so that rinsing of the bell cup is also made possible during the coating operation in order to prevent it from adhering coating agent residues clean.
  • the term of a rinsing agent channel which is separate from the coating agent channel is to be understood as meaning that there is no connection between the coating agent channel and the rinsing agent channel in the bell-shaped plate, so that it does not form a rinse during the coating operation Mixing of detergent and coating can come.
  • the coating agent channel and the detergent channel are thus supplied separately with rinsing agent or coating agent in the preferred embodiment.
  • the flushing agent channel and the coating agent channel preferably have spatially and / or fluidically separate inlet openings or inlet openings.
  • the rotary atomizer according to the invention has a coating agent channel and a separate flushing agent channel, the outlet opening of the flushing agent channel being separated from the outlet opening of the coating agent channel in order to be able to conduct the flushing agent separately from the coating agent channel to the bell cup.
  • the outlet openings of the detergent channel and the coating agent channel are therefore preferably fluidically and / or spatially separated.
  • the invention is not limited to use in the powder atomizer described above, in which a powder is used as coating agent. Rather, it is theoretically also conceivable that the invention is used in a rotary atomizer and a correspondingly adapted bell cup for liquid coating compositions.
  • the rinsing agent channel arranged in the bell cup therefore preferably has an outlet opening which is directed onto the high-voltage electrode in order to prevent contamination of the high-voltage electrode by sprayed-on coating agent during the coating operation.
  • This flushing of the high-voltage electrode during the coating operation advantageously prevents deposition of coating agent on the high-voltage electrode, so that even in a long-lasting coating operation, no interruptions are required to clean the high-voltage electrode.
  • the high-voltage electrode has an electrode needle, wherein the flushing agent flow is substantially jacket-shaped and coaxial with the electrode needle.
  • the electrode needle is thereby always surrounded during the coating operation by a protective detergent layer, whereby deposits of coating agent are prevented at the electrode needle.
  • the coating agent channel runs as in the case of the known powder atomizer described above an inner part and an outer part of the bell cup, wherein the inner part is connected by at least one hollow connecting bolt with the outer part, while the detergent channel passes through the hollow connecting bolt.
  • the connecting bolt thus serves on the one hand for mechanical fixation of the inner part of the bell cup on the outer part of the bell cup and also forms part of the detergent channel.
  • the fixing of the connecting part in the inner part of the bell cup is in this case preferably by a fastening screw, wherein the head of this fastening screw is preferably supported on the inner part of the bell cup, while the thread of the fastening screw engages in an internal thread which is attached to the inner wall of the hollow connecting bolt.
  • the fastening screw in this case has an axially continuous bore for the passage of the rinsing agent, so that the hollow connecting bolt is not closed by the fastening screw.
  • the bell cup dishwashing agent runs on rotation of the bell cup with the bell cup, wherein in the bell cup to achieve a sufficiently large detergent flow preferably more detergent channels are arranged, which can be distributed, for example, distributed over the circumference of the bell cup at regular angular intervals.
  • the supply of the rinsing agent to the bell cup is preferably carried out by the rotary atomizer, which for this purpose has a separate detergent channel, which is separated from the coating agent channel of the rotary atomizer. It is also important that the outlet opening of the detergent channel of the rotary atomizer is separated from the outlet opening of the coating agent channel of the rotary atomizer, so that the rotary atomizer the dish can be supplied to the bell cup separately from the coating agent during the coating operation.
  • the supply of the rinsing agent is not carried out by the rotary atomizer, but by the bell cup itself according to the invention.
  • the bell cup therefore has a turbine which rotates with the bell cup, wherein the turbine sucks ambient air and promotes in the arranged in the bell cup detergent channel.
  • This variant of the bell cup according to the invention also makes it possible, with a conventional rotary atomizer without a separate detergent channel, to rinse the bell cup during the coating operation.
  • the rinsing agent channel arranged in the bell-shaped plate has an inlet opening whose cross-sectional surface extends at right angles to the axis of rotation of the bell-shaped plate. Accordingly, the rinsing agent channel arranged in the rotary atomizer then also has an outlet opening whose cross-sectional area extends at right angles to the axis of rotation of the bell-tower shaft.
  • the inlet opening of the rinsing agent channel arranged in the bell cup is then located with a slight gap in front of the outlet opening of the rinsing agent channel arranged in the rotary atomizer, whereby a dynamic sealing is effected.
  • the rinsing agent channel arranged in the rotary atomiser preferably discharges into the rotary atomiser into an annular channel which is arranged coaxially with the bell-shaped plate shaft and has an outlet opening which runs annularly with respect to the bell-plate shaft.
  • the flushing agent channel is preferably arranged fixedly, but it is theoretically also possible that the flushing agent channel in the rotary atomizer rotates with the bell-tower shaft.
  • the invention is not limited to ambient air or compressed air with regard to the rinsing agent to be used. Rather, it is also possible to use other rinsing agents that are well known to those skilled in the art.
  • FIG. 1 shows a rotary atomizer 1 for powder coating of workpieces and a correspondingly adapted bell cup according to the invention 2.
  • the rotary atomizer 1 is suitable in connection with the bell cup 2 in particular for powder coating of motor vehicle body parts in series production, but also the coating of other workpieces is possible.
  • the bell cup 2 consists essentially of an outer part 3 and a coaxial to him, axially spaced from him inner part 4, wherein between the outer part 3 and the inner part an annular gap-shaped coating agent channel 5 extends, as shown in the interior of the bell cup 2 over the entire circumference of Bell plate 2 extends and widens conically in the axial direction to the free end of the bell cup 2.
  • the boundary surfaces of the coating channel 5 formed by the outer part 3 and the inner part 4 do not run exactly parallel, but approach the mouth opening of the coating channel 5, so that the cross section of the coating medium channel 5 decreases towards the mouth opening, which accelerates the Coating agent stream in the coating agent channel 5 leads.
  • a middle part 6 is centrally used that seamlessly merges at the side lying right in the drawing into the inner part and has a tip which tapers conically towards the rotary atomizer 1 facing side of the bell cup 2.
  • a cup-shaped cylindrical recess into which an insert body 7 is inserted, wherein the insert body 7 has an axially continuous bore through which a centrally disposed electrode needle 8 a high voltage electrode protrudes axially outward.
  • the high-voltage electrode 9 is under high voltage during the coating operation and serves to electrically charge the powder-air mixture discharged from the bell cup 2 and to ionize the air space between the rotary atomizer 1 and the workpiece to be coated.
  • the mechanical connection of the inner part 3 with the outer part 4 is effected by a plurality of axially extending hollow connecting bolts 10, which are arranged distributed over the circumference of the bell cup 2 at equal angular intervals.
  • the fixing of the connecting bolt 10 in the inner part takes place here by a fastening screw 11, the head of which is supported in the inner part 4, wherein the fastening screw 11 has an external thread which engages in the mounted state in an internal thread in the hollow connecting bolt 10.
  • the connecting bolt 10 For fixing the connecting bolt 10 in the outer part 3, the connecting bolt 10, however, on the rotary atomizer 1 side facing a thickened relative to the shaft portion of the connecting bolt 10 head, which is supported when tightening the fastening screw 11 on the outer part 3.
  • the bell cup 2 makes it possible to rinse the electrode needle 8 with purging air, the purging air stream flowing around the electrode needle 8 in an axial and jacket-like manner, as can be seen from the drawing.
  • the scavenging air is supplied here in the bell cup 2 by a scavenging air channel, the scavenging air channel initially being formed from the electrode needle 8 by a radially extending needle bore 12 which merges into a corresponding connecting bore 13 in the middle part 6.
  • the detergent channel in the bell cup 2 is then formed by a bore which passes axially through the fastening screw 11 and connects the interior of the hollow connecting bolt 10 with the connecting bore 13, so that the interior of the connecting bolt 10 forms part of the detergent channel.
  • the supply of the rinsing agent to the detergent channel of the bell cup 2 takes place here by the rotary atomizer 1, which also has a detergent channel, which runs in a housing 14 of the rotary atomizer 1, wherein the detergent channel of the rotary atomizer 1 is formed by a plurality of lines 15 - 18, the finally open into an annular channel 19, which has an annular circumferential outlet opening, wherein the outlet opening of the annular channel 19 is located on the free end face of the rotary atomizer 1 and is mounted with the bell cup 2 with a small gap in front of the mouth opening of the hollow connecting bolt 10, so that regardless of the rotational position of the bell cup 2 always purge air from the annular channel 19 can pass into the flushing channel of the bell cup 2.
  • the rotary atomizer 1 has a rotatably mounted bell-plate shaft 20, which carries an internal thread at its free end.
  • the outer part 3 of the bell cup 2 has a correspondingly adapted external thread, so that the bell cup 2 is screwed onto the bellcylinder shaft 20 in the mounted state.
  • the rotary atomizer 1 has a coating agent channel 21, which is formed by the interior of a centrally arranged powder tube 22.
  • the coating agent channel 21 is thus separated from the flushing agent channel 15-19, wherein the outlet openings of the coating medium channel 21 and the flushing agent channel 15-19 are also separated from one another in order to allow independent supply of flushing agent and coating agent.
  • the coating agent channel 5 in the bell cup 2 is separated from the detergent channel 12, 13 in the bell cup 2, so that the rinsing of the electrode needle 8 can take place during the actual coating operation.
