Method and system for painting workpieces

摘要

The method comprises applying a non-lacquered first area of a workpiece (20a) with a protective layer (40c), and lacquering a second area of the workpiece in a subsequent lacquering process by using a first lacquer, where the second area partially covers the first area and the protective layer is applied as liquid film material. A time period, in which the protective layer hardens, is provided between the application of the protective layer and the subsequent lacquering process. The protective layer is removed after the subsequent lacquering process of the second area. The method comprises applying a non-lacquered first area of a workpiece (20a) with a protective layer (40c), and lacquering a second area of the workpiece in a subsequent lacquering process by using a first lacquer, where the second area partially covers the first area and the protective layer is applied as liquid film material. A time period, in which the protective layer hardens, is provided between the application of the protective layer and the subsequent lacquering process. The protective layer is removed after the subsequent lacquering process of the second area, and is applied by an application device (28), which is moved by an industrial robot (22). A third area of the workpiece is lacquered in the lacquering process by using a second lacquer before applying the protective layer, and is partially covered by the first area. A time period, in which the used lacquer hardens for lacquering, is provided between the lacquering of the third area and the application of the protective layer of the first area. The workpieces are partially moved by using an automatic conveying device during lacquering process and/or during applying the protective layer. The liquid film material flows into liquid film material rods, which parallely lie next to each other, from the application device during applying the protective layer. The liquid film material rods run together for the protective layer after striking on the first area of the workpiece. The number of the liquid film material rods is varied during applying the protective layer. The movement of the industrial robot and/or the control of a part of the application components required for applying the protective layer are given by a common controller. The lacquering process is carried out by a lacquering device (24), which is moved by a further industrial robot. An independent claim is included for a lacquer system.
