Definitions

  • a method of the type mentioned is from the EP 1 172 152 A1 known. It is particularly well everywhere, where with a frequent change of processed by the paint application device Lackart, z. B. a change in paint color is expected. The amount of paint required in each case for a coating operation is thereby pushed through as well as at the forward and at the trailing end well-limited liquid column through the pig pipe. In this way, on the one hand, the inner circumferential surface of the pig pipe is not or only slightly contaminated with the respectively transported paint; on the other hand is also the risk that in the transported between the pig paint volume impurities are introduced, comparatively low. Nevertheless, it is necessary, at least at certain intervals, especially in a color change, to clean the inner surface of the pig pipe with a cleaning agent.
  • Object of the present invention is to provide a method of the type mentioned in such a way that with the least possible expenditure on equipment a good cleaning of the pig pipes is possible.
  • a comparatively large volume for the cleaning fluid available so that is to be expected with a good cleaning effect.
  • the pigs may in the present invention have a very simple, conventional construction and also need not be very long.
  • compressed air is used as the pushing medium for the pigs.
  • Compressed air brings in the system virtually no impurities and can be discharged into the atmosphere, so that the use of a closed sliding medium system as in the EP 1 172 152 A1 is not required.
  • a liquid solvent is suitably used as a cleaning agent.
  • the speed of the pigs can be adjusted simply by correspondingly throttling the displacement of the air from the flow paths lying in front of the pigs. The stronger the throttling, the slower is the pig movement.

  • the measurement of the applied in the space between the pig paint can be done outside the pig station in the paint supply with high precision.
  • the pressurized cleaning agent is used as a pushing medium.
  • an embodiment of the invention is recommended in which the supply of cleaning agent into the space between the two pigs in the second pig station ends is when the leading pig has moved a certain distance, in which case the trailing pig is moved together with the detergent volume and the leading pig through the pusher medium.
  • the accuracy of the volume measurement which takes place by measuring the distance of the leading pig, is thus completely sufficient.
  • the pig stations should also be rinsed with detergent at least during a color change.
  • the pig stations are rinsed alternately with detergent and compressed air. Due to the alternating, pulsed impingement with liquid detergent and compressed air, a particularly high cleaning effect is achieved.
  • the paint application device has an electrode which can be placed on high voltage.
  • internal charging in which the paint to be applied comes into contact with the high-voltage electrode within the paint application device, the problem of galvanic separation between the paint application device and the adjacent system components arises from the paint supply source, which is generally at ground potential.
  • the high voltage is applied to the paint application device only when the pigs are at a certain minimum distance outside the pig stations in the pig pipe. The minimum distance is chosen so that the required galvanic separation is ensured on the corresponding route of the pig pipe without the risk of electrical recoil.
  • the cleaning agent is supplied to the high voltage suspendible components via a line and discharged from these components via a line whose length is artificially extended by winding in a certain range.
  • the complex pigging method for galvanic separation is not used. Rather, by a corresponding length of the lines, which usually exceeds the geometric reasons required length of the lines considerably, provided for a sufficiently high electrical resistance between the high-voltage components of the system and the components lying at ground potential of the system.

Abstract

L'invention concerne un procédé permettant d'alimenter un dispositif d'application de peinture (1) en peinture. Selon ce procédé, une quantité déterminée de peinture est respectivement transportée entre deux racleurs (10a, 11a, 10b, 11b) à travers une conduite de raclage (35a, 35b), d'un première poste de raclage (6a, 6b) qui peut être relié à une source d'alimentation (2) en peinture vers un second poste de raclage (7a, 7b) qui peut être relié au dispositif d'application de peinture (1). La conduite de raclage (35a, 35b) est nettoyée sur le chemin inverse, du second poste de raclage (7a, 7b) vers le premier poste de raclage (6a, 6b), par un produit nettoyant qui est également transporté entre les deux racleurs (10a, 11a, 10b, 11b). Ainsi, il est possible de nettoyer la conduite de raclage (35a, 35b) de manière fiable au moyen de racleurs (10a, 11a, 10b, 11b) configurés simplement, ce qui est particulèrement important lors d'un changement de couleur.
