Definitions

  • the invention relates to a coating device with a rotary atomizer mounted on a coating machine for the serial coating of workpieces and a method for controlling the operation of such a coating device according to the preamble of the independent patent claims.
  • the bell cup of the usual electrostatic series coating of workpieces such as vehicle bodies rotary atomizer of compressed air turbines with extremely high speeds is driven (DE 34 29 075, DE 43 06 800, EP 0 796 663, EP 0 801 991, etc.).
  • the air flowing through the turbine has about the temperature of the environment when entering the atomizer and is cooled due to the relaxation in the turbine to temperatures that depend on the turbine performance and in the usual coating systems, for example, in the order of up to -20 ° C lay. If u.a. Due to the recent strong increase in the desire for even higher speeds and Lackaus Wegmengen the performance of the turbine is to be further increased, cooling of the air at the turbine outlet to values below -40 ° C can result.
  • the exhaust air of the turbine could interfere with the coating process, if it would emerge directly at the atomizer in the cabin, it is usually through the atomizer carrying arm of the coating machine such as a painting robot through, so that, for example, the surfaces of the flange connection between the atomizer and the wrist of the machine and the adjacent areas of the machine arm are cooled with the result of appropriate condensation.
  • the resulting drops of water can cause paint defects.
  • a electrostatic rotary atomizer with a turbine connected to storage, drive and brake air lines containing these lines compressed air line includes a heater whose purpose is to evaporate contained in the compressed air drops of water.
  • the object of the invention is to specify a coating device or a method which, as far as possible, prevents the condensation of the ambient air on components of the atomizer and / or the coating machine as much as possible, especially in the case of electrostatic rotary atomizers with high drive power.
  • a first measure to prevent the formation of condensation is the heating of the drive gas of the turbine, which is usually compressed air. With the heating of the drive air in some coating systems too high a cooling can be avoided, but above all an immediate heating of the exhaust air of the turbine is expedient, while with exclusive heating of the supply air, a portion of the heat energy by heat conduction on the less affected by the formation of condensation air supply side the atomizer is lost and / or unwanted heating of local components of the atomizer entails. In general, the possibility of heating by the maximum permissible temperatures of the affected Components or line hoses, etc. limited about plastic.
  • the heating of the exhaust air of the turbine can be particularly expedient via a heat exchanger, which on the one hand depends on the exhaust air and on the other hand on the supply air of the turbine or also on a separately supplied liquid or gaseous medium, such as e.g. heated air is flowed through. If the heated supply air is passed through the heat exchanger, so a single heater is sufficient to heat the supply air and as an additional measure of the exhaust air, without resulting in additional heating air consumption at two different locations. It is also advantageous that undesirably high heating of supply air ducts and adjacent components can be avoided.
  • the exhaust air of the turbine can also be heated by admixing warm air.
  • warm air For example, directly at the outlet opening of the bearing unit of the turbine compressed air from the existing compressed air network of the coating system or conveyed by a fan air into the exhaust air flow can be passed.
  • the amount and temperature of this additional air can be set to relatively low values depending on the exhaust air temperature and the humidity in order to avoid the unwanted condensation.
  • the cooling of the components by relaxation of the drive air of the turbine depends on the load and is the stronger, the higher the speed, the amount of paint sprayed per unit time, the diameter or mass of the bell cup and the temporal efficiency of the atomizer during a painting cycle.
  • higher air consumption rates are required for increasing loads, which in turn increase the cooling.
  • other measures may be advantageous in highly loaded atomizers in addition to or even instead of heating the drive air of the turbine.
  • a suitable option is u.a. the heating of the bearing air of the turbine whose shaft rotates in a conventional manner in an air bearing.
  • the heating of the bearing air has the advantage that the bearing air flows through a large part of the turbine and this can heat more uniformly.
  • the air volumes and thus the heat capacity of the bearing air are relatively low. It may therefore be desirable to have larger amounts of heated air (for example of the order of 100 l / min) separated by the path of the propulsion air, that is, additional, e.g. to guide channels of the storage unit and / or other constituents of the atomizer or of the coating machine not provided in known atomizers and coating machines.
  • shaping air which flows past in known manner, possibly in different ways on the bearing unit of the turbine and / or flows through the turbine (DE 102 33 198).
  • the shaping air temperature is in this case adjusted so that the spraying cone formed by the forming air is not impaired and no undesirable influence on the painting process is observed.
  • endangered components of the atomizer and / or the coating machine can also be heated directly by condensation of the cabin air.
  • the flange construction on the robot wrist, the wrist and / or the robot arm may contain corresponding channels for the heated media.
  • the temperature of the air or other media supplied for reducing the cooling is controlled according to the invention generally in dependence on one or more temperature sensors which For example, measure the temperature of the supply air and / or exhaust air of the turbine, the engine bearing air, possibly the steering air and / or adjacent to the supply and exhaust air paths of the turbine air components of the atomizer or the coating machine and with an associated controller appropriate in the closed loop preheating can control.
  • the preheating temperature can also be controlled as a function of load based on predefined diagrams or stored program data as a function of the speed and paint quantity.
  • an electrical heater for the atomizer for the purpose described here preferably electrically insulating heating media outside the nebulizer has the advantage, especially with electrostatic atomizers with direct charging of the coating material that problems regarding the required potential separation between the heater and lying on high voltage potential components the atomizer can be avoided.
  • an electrically conductive heating fluid such as e.g. Water or an electric heating coil can be used in this case.

  • the shaping air is then guided past the compressed-air turbine 5 into a so-called air space 16, from where it finally reaches the shaping air nozzle 8 through tap holes 17 in the shaping air ring 6.
