DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention is related to a method of entering and displaying the adjustment parameters of an apparatus for coating objects, particularly vehicles or vehicle parts that are moved into coating positions by a transport apparatus, with at least one spraying or atomizing tool being disposed in a coating station so as to be stationary or to move relative to the objects, and having control elements which are controlled according to the adjustment parameters.
Apparatuses for automatic coating of objects, such as vehicle bodies, with spraying tools are already known which are connected to a program-control apparatus. The program-control apparatus sets the parameters of the spraying apparatus corresponding to the work steps. The objects are guided through coating positions with a transport apparatus (DE 30 14 114).
For coating of, for example, vehicle bodies, painting paths through are used through which the bodies are moved with a transport mechanism. The painting paths are divided into at least three path segments, namely the segment for color preselection, the segment of type recognition and the actual painting segment. As the body passes through the color preselection segment, the desired color is predetermined via an input keyboard of the program control.
During passage through the color preselection segment, rinsing processes are performed, either automatically or by operating personnel, in a controlled manner. Colors are to be selected for the bodies. Color selection values can also be canceled or corrected within the color preselection segment. Furthermore, repetition of the color selection is possible by means of a corresponding command. In a color change, a rinsing process is performed, by means of which the spraying elements, such as spraying heads or atomizing heads, and the lines are cleaned. Painting is performed as a function of the type. Therefore, the type of the respective body is entered into the program control. In the type-recognition segment, the type of the body passing through is determined with sensors. A corresponding painting program is selected by the program control as a function of the type.
Different atomizing devices or spraying devices that can be stationary or movable are located in the painting segment. Stationary atomizing apparatuses are, for example, disposed staggered in height next to the object. A vertically-movable roof-spraying device can further be provided.
Underlying the invention is the problem of developing a method with which the adjustment parameters of a coating apparatus for objects can be monitored with respect to coating objects, and entered as comprehensively as possible for the respective coating process, and represented.
SUMMARY OF THE INVENTION
According to the invention, the problem is solved in that, on the monitor of a personal computer which either stores parametrization data generated by an input apparatus for the coating apparatus offline or further conducts them online to a program control connected to the coating apparatus, the monitor having at least one window, a graphic view of the object and, next to the view of the object and on the correct scale, the coating surface of the at least one spraying tool present on the surface are represented, that coating zones following one after the other in the transport direction of the object are represented schematically by rectangles along a line extending through the center of the represented spraying tool in the view of the object, the length of the rectangles being a measure for the length of the coating zones, and their height being a measure for an adjustment value of the spraying tool, that rows of an input field containing numerical information about the type of displayed object and the identification of the spraying tool that can be called up via the input apparatus for parametrization are displayed below the view of the object, and at least the coating zone lengths are displayed with a further adjustment value that can be parametrized, and that the off- or online op
