Definitions

  • the invention relates to a method and a control system for a system for automatic coating of one edge of the object to be coated limited area according to the preamble of the independent claims.
  • the invention relates in particular the series painting of relatively large areas Workpieces such as Parts of vehicle bodies, but it can whole workpieces in the area to be coated or small parts put together to form a painting field.
  • a typical example is that known in robot painting Applying parallel, overlapping paths to one another at least approximately rectangular area under the control of stored movement and coating programs (DE 101 50 826). This results in two to opposite as the edge paint Long parallel edges and for the sides of the surface the other two sides of the surface are parallel to these sides short connecting track sections between the end points of the long edge tracks.
  • the ideal setting of the painting parameters (High voltage, flow rate, speed, steering air, painting speed, Painting distance, angle to surface) often deviates from the ideal setting of the painting parameters surface painting without edge areas.
  • the parameters changed on a path and thereby also at the path end points are, but these parameter changes are from the perspective of Dynamics and reproducibility often do not make sense in practice.
  • the previously usual methods thus have disadvantages like not optimal coating of the edge and / or inner areas of the coating surface due to the use of the same parameters, unevenly coated edges due to the web turning points and Overspray losses too high.
  • the invention is the Task based on specifying a method or system in which these disadvantages are avoided and one over the entire area optimal coating of the object to be coated with low Overspray loss is made possible.
  • the method described here can therefore be the one to be coated Area partially or over its entire circumference Frames with one or more edge sheets are drawn, the one under control by ideally on the edge area in particular with regard to paint distribution, edge painting, layer thickness build-up and efficiency-optimized parameters are generated.
  • the as Filling area remaining inside can be used for surface coating especially with regard to layer thickness distribution, Efficiency and pollution optimized parameters coated optimal overlap, preferably with parallel paths enable.
  • the webs required to coat the surface can e.g. depending on the painting concept by an atomizer or also on several atomizers can be generated split. For example can therefore one or more edge tracks with the one atomizer and the lanes of the interior with another atomizer be applied.
  • the order of the coating i.e. whether e.g. first the Frame or first apply the interior panels, depends on the conditions of the particular application such as for example from the available painting time, the Painting concept, the number of atomizers or others themselves parameters affecting the process.
  • the adaptation path can be determined by the geometry of the coating Area-related, for example non-parallel Compensate outer contours or differences that arise if the area between the border or frame areas cannot be divided optimally or evenly.
  • the adaptation path can vary depending on the geometry of the surface to be painted with itself along the path in steps or evenly or continuously changing painting parameters such as steering air, flow rate, Painting speed, painting distance, high voltage, Speed, etc. are generated.
  • the surface of the component 1 shown in FIG. 1 should, for example in the usual way for body painting Way with a painting robot or other program-controlled multi-axis coating machine mounted electrostatic Rotation or air atomizers can be painted.
  • the surface according to the invention is in two each divided areas to be painted separately, namely into one Edge region 2 running over the entire circumference of the surface as a frame with a predetermined width and within the Frame remaining interior area 3.
  • the coating system has its own set of painting parameters such as amount of paint, spray cone formation, etc. (usually referred to as Brush), which controls the respective atomizer for the webs of paint or other to be produced Coating material is used.
  • Brush which controls the respective atomizer for the webs of paint or other to be produced Coating material is used.
  • Fig. 2 are the example of a component 10 with a non-rectangular Shape the in the edge region 12, which as in Fig. 1st forms the surrounding frame, path to be generated and the paths for the remaining inner region 13 to be filled is shown in more detail.
  • Sub-areas can be divided, each by its own Group of longitudinal tracks 16 to 23 with associated matching track 24 is coated. Lanes 16 to 23 inclusive corresponding to the short connecting tracks 21 and 22, generated under the control of the aforementioned second program Coating path is designated 15.
