Definitions

  • the invention relates to a method for operational control an electrostatic coating system and such plant suitable for carrying out the method.
  • an electrostatic coating system and such plant suitable for carrying out the method.
  • electrostatic Coating systems are known to be high voltage generators of cascade type, whose control system during the coating either the voltage or that of the atomizer supplied current can keep constant (US 4,737,887, EP 0 283 936 B2).
  • the cascades of the known coating systems can be between Constant voltage mode and constant current mode switched become. Depending on the setting, changes to the maximum permitted voltage or the maximum permitted Current possible by manual switching.
  • the well-known systems do not always allow the best combinations of voltage and current for optimal charging of the sprayed Coating material, especially when there are operating conditions to change.
  • the invention has for its object a better adaptation the coating device supplied voltage and To allow current values to the respective operating conditions. In particular, for example, if only a small Voltage is possible for the coating device Compensation to be able to supply the highest possible current, and vice versa.
  • variable Setting limit values for both current and the voltage always the best possible product from these parameters (UxI) set for optimal charging and as far as possible can be met.
  • UxI variable Setting limit values
  • one parameter e.g. the Voltage
  • the highest possible limit is specified as the setpoint be adhered to during the coating process as long as the limit value for each other parameters (here the current) are not exceeded becomes.
  • the parameter on the predetermined limit or setpoint remain constant, he can but also fluctuate due to the operating conditions only "quasi" constant).
  • Parameters can be the parameter on the setpoint regulated down to the required extent by the control circuit of the cascade so it sinks because of this active Control below its own limit and the previous one Setpoint from.
  • the limit value of at least one of the two parameters for adaptation the coating company to different coating devices Coating tasks or other operating conditions be changed.
  • the change can be gradual by automatically switching the cascade through the higher-level control system of the plant.
  • the limit for the current is now reduced and as soon as it is achieved in operation, exceeding by down-regulation which prevents tension. Instead of the previous one stiff or "hard” control characteristic curve results here a "softer" regulation.
  • the drawing shows in the lower part the three predetermined current limit values Imax 1 , Imax 2 and Imax 3, which are smaller along the time axis t from stage to stage, and in the upper part the associated maximum values Umax 1 , Umax 2 and Umax 3 of the voltage U, their the actual course of time is shown.
  • the mentioned exterior painting takes place until time t 1 . If the current limit is then reduced to Imax 2 for painting other areas, assuming that the limit is reached and exceeded, the voltage inevitably drops back to the corresponding value Umax 2 , since it regulates to the same extent from the cascade control system becomes.
  • the current limit is then reduced to an even lower value Imax 3 at time t 2 and consequently the correspondingly low voltage Umax 3 is set as shown.
  • the setpoint and limit values for voltage and current can be used with the system described here by stored data of the parent Program control system of the coating system specified and be accessed to control the cascade.
  • different Available limit values can also be in one own data storage of the control system of the high voltage generator filed and as needed, d. H. depending on the desired Characteristic curve can be retrieved from the higher-level control.
  • Control operations are based on both the actual voltage Atomizers as well as their current constantly measured and with the predetermined target and limit values compared.
  • For comparison and as an actuator for down-regulation when reaching the Current or voltage limit values are, for example, those in the control system to control the high voltage per se Operational amplifier suitable.
