Definitions

  • the invention relates to a method for automatic serial coating of workpieces such as in particular the components and / or attachments of vehicle bodies with electrically conductive coating material and a coating system for carrying out the method according to the preamble of the independent claims.
  • An alternative solution which is important in practice is external charging of the coating material sprayed by a rotary atomizer through the atomizer on a concentric ring surrounding in finger-like pins of insulating outer electrodes, which make it possible to keep the coating material into the atomizer at ground potential (US 3 393 662, DE 199 09 369; DÜRR / BEHR Technical Manual, Introduction to the Technology of Passenger Car Painting 04/1999, Chapter 4 Atomizers).
  • a variant This alternative method is to arrange the outer electrodes directly on the atomizer housing (EP 1 362 640).
  • the coating material is not supplied to the atomizer from the remote supply device via a line system, but from cartridges mounted in or on the atomizer or in its vicinity, which are removed again after use (EP 0 274 322).
  • EP 0 796 665, EP 0 967 016) is also known to replace the entire atomizer including a cartridge contained therein and refill (EP 1 245 296, WO 01/15815).
  • Another problem with the series coating of workpieces is the requirement for preferably fully automatic coating of all workpiece areas including possibly narrow and / or not easily accessible areas such as in particular of interior areas and possibly including attachments of the workpieces in the same cabin.
  • both the outer surfaces of the body and, as far as possible, all interior areas including the doors and the engine and luggage compartments as well as bumpers, exterior mirrors, etc. are to be coated in a cabin.
  • An important reason for this is the desire for high flexibility of the coating operations, increase in productivity, lower paint losses and last but not least capital investment.
  • air atomizers are currently used both manual and automatic application, because they are on the one hand much less bulky than that for the Exterior painting conventional and proven rotary atomizer with external electrodes and on the other hand also avoid the mentioned problem of electrical isolation.
  • air atomizers have a poorer application efficiency than rotary atomizers (which is here meant high-speed atomizers with bell speeds of typically more than 20,000 rpm), which is defined as the ratio of the sprayed to the amount of material deposited on the workpiece, and other principal disadvantages such as high pollution through overspray.
  • rotary atomizers which is here meant high-speed atomizers with bell speeds of typically more than 20,000 rpm
  • the ratio of the sprayed to the amount of material deposited on the workpiece and other principal disadvantages such as high pollution through overspray.
  • a higher air sink rate in the cabin is necessary than with rotary atomizers, whereby the operating costs are increased.
  • the invention is based on the object, the coating of workpiece areas, of the rotary atomizer used for coating other workpiece areas with external electrodes are difficult to reach for external charging of the coating material, without potential separation problems, but at the same time to allow better application efficiency than when using air atomizers.
  • the invention is based on the finding that the coating of the externally charged or poorly achievable for other reasons less suitable for the electrostatic coating with external charging workpiece areas or workpieces is also possible with relatively good efficiency, if you rotary atomizer eg both for outdoor areas and for Indoors without the known direct charging of the coating material to the atomizer bell and thus used without potential separation problems. In any case, the efficiency is better than in the case of air atomization, the solution hitherto customary in practice for avoiding the potential separation problem in the inner coating.
  • the advantages of the electrostatic coating with external charging can be combined with the advantage of unrestricted accessibility of workpiece areas by rotary atomizers without external electrodes in the complete automatic coating of workpieces in a cabin or zone with the same manipulator machine, especially in the combined interior and exterior painting.
  • the efficiency of the non-electrostatic coating with high-rotation sputtering is lower than in the case of external charging, the cabin or zone has a significantly higher overall efficiency than when air atomizers are used.
  • the manipulator machine is preferably one of the robots customary for vehicle painting.
  • the coating according to the invention can therefore take place in two steps, preferably with the same device: Coating with charging of the coating material or without charging of the coating material. Both steps can be carried out alternately, wherein in the second step, the outer electrodes can be switched off or preferably removed.
  • the invention When using the same rotary atomizer for both the electrostatically and non-electrostatically coated workpiece areas, the invention also has the advantage that during the non-electrostatic coating, the external charging parts removed from the atomizer can be cleaned. This eliminates the previous principal disadvantage of business interruptions in the regular Periods required cleaning of external charging atomizers.
  • the non-electrostatic coating only components of the external charging device are deposited, for example only the finger-like insulating pins in which the electrodes are seated, or even the entire external charging device, possibly also together with an outer housing of the atomizer.
  • the outer electrodes or their holding elements and / or other components of the external charging device of the rotary atomizer can be deposited during the non-electrostatic coating and preferably likewise cleaned during the non-electrostatic coating, for example by an automatically controlled cleaning device provided at the depositing point.
  • the parts to be deposited or cleaned are brought by the manipulator machine to the storage or cleaning points.
  • the cleaning on at least one separate cleaning point, to which the parts of the outer electrode arrangement to be cleaned and / or the atomizer to be cleaned are brought by the manipulator machine.

  • the atomizer can be cleaned by itself, so without external electrodes.
