Verfahren und Vorrichtung zum Austragen von Beschichtungsmaterial

Disposable containers are provided for containing different types, for example, different colors, of coating material to be dispensed onto one or more articles (26). A method of coating articles includes providing a dispensing device for dispensing coating onto the articles. A high-magnitude potential supply (28) is selectively coupled to the dispensing device (30) for supplying electrostatic charge to the coating as the coating is being dispensed. A first disposable container (22-n) containing a first coating material to be dispensed onto a first one of the articles is coupled to the dispensing device (30) as the first article (26-n) is presented for coating, and the first coating material is dispensed onto the first article. A second disposable container (22-(n+1)) is filled with a second coating material to be dispensed onto a second one (26-(n+1)) of the articles, for example, while the first coating material is being dispensed onto the first article. Upon completing coating of the first article with the first coating material, the supply of high-magnitude potential to the dispensing device is interrupted, and the first container (22-n) is uncoupled from the dispensing device (30). The first coating material is flushed from the dispensing device (30). The second container (22-(n+1)) containing the second coating material is coupled to the dispensing device, and the supply of high-magnitude potential to the dispensing device (30) is resumed as the second article (26-(n+1)) is presented for coating.
