Definitions

  • FIGS. 2 and 3 now show an embodiment of an electrode arrangement 6 according to the invention and to explain the method according to the invention.
  • This electrode arrangement 6 can be used directly instead of the electrode arrangement 6 ′ shown in FIG. 1.
  • the same reference numerals show the same elements, in particular the purge air line is again designated by 14 and the purge air by arrows 17.
  • the electrode 29 is rigid and only follows the movement of the vibrating base.
  • This base can in turn be driven piezoelectrically, electromagnetically or electromotively or in another known manner to carry out vibration. These vibrations can take place in the direction of arrow C and / or arrow D.
  • a tip electrode which is cylindrical and rigid in its lower region can be vibrated, for example in a range from 100 Hz to likewise 500 Hz or higher.
  • the deposition of coating material by vibration of the electrode can also be prevented in this way.
  • purge air 17 can be used in a known manner, so that the purge air is used for flushing and is not used to generate vibrations.
  • the electrode is not vibrated, but is moved in another way, preferably rotated about an axis E.
  • two electrodes 39 are arranged in the electrode arrangement 6 on a carrier 38 which, together with the shaft 37, can be rotated about said axis of rotation E.
  • the electrodes are in turn connected to the voltage source U.
  • the rotation can take place, for example, by means of an electric motor, or an air flow, for example the purging air flow 17, could in turn be used to drive the electrodes 39, which is possible by means of a corresponding wind turbine-like configuration of the carrier 38.
  • the electrode arrangement 6 is stationary with respect to the objects 3, which are in turn moved, and only the individual electrode or the individual electrodes 39 are moved.

Abstract

Lors du revêtement électrostatique d'objets, par ex. de boîtes de conserves, le matériau de revêtement est chargé au moyen d'une électrode (9). Pour éviter des dépôts de matériau de revêtement sur l'électrode, ladite électrode est mise en vibration. A cet effet, l'électrode est conçue en tant que languette qui est mise en oscillation par l'intermédiaire d'un courant d'air (17).
