Definitions

  • the invention relates to a powder coating system for the Series coating of workpieces according to the generic term of Claim 1.
  • the invention has for its object a powder coating system to indicate with a coating machine that the Color change not only with less equipment and time and less space required, but above all reduces the risk of coating errors, which in known Systems due to deposits that are difficult to remove in particular in the line common to the colors becomes.
  • the powder coating is conveyed in the system described here from the color changer to the atomizer or other application organ no longer due to the injector technology previously used, but by the spatially of the fixed powder supply system separate, according to the invention to be supplied with Application member movable, for example with a movable Robot conveyor unit with which the powder can also be dosed. Because the moving unit too contain the color changer upstream of the conveyor unit can, the length of the common to the selectable colors Only the hose through the machine to the atomizer or other application organ leading route. Furthermore, a metering pump can be used as the delivery unit, which is a powder feed without the previous tendency to deposit allows. Both have a significant improvement in Painting quality result because the workpieces to be coated such as B. vehicle bodies no longer with foreign paint, Powder agglomerates etc. are contaminated because there are fewer deposits form that peel off during painting could.
  • the system shown in Fig. 1 contains a painting robot 1, which is parallel to a rail construction 2, for example vehicle bodies to be coated can be moved to the conveying direction is. This degree of freedom and the associated one Robot parts are usually referred to as a driving axle.
  • An atomizer 3 is mounted on the wrist of the robot Design and functions of any known powder coating system can correspond.
  • a unit 4 which contains a color changer 5 and a metering pump 6.
  • the design of the color changer is arbitrary in itself, but can be useful the device described in DE 10125648 correspond to a connected to the atomizer Contains paint tube that is relative to a motor drive Arrangement of several each connected to an ink supply line Paint connections are movably mounted.
  • the dosing pump 6 is explained in more detail with reference to FIG. 3.
  • the output of the color changer 5 is over with the atomizer 3 one by the robot 1 and by its wrist until immediately connected to the atomizer opening hose 7.
  • the each a selectable color assigned input connections of the Color changer 5, on the other hand, are movable with respective tubes 8 Color reservoirs 9 connected to the fixed Form powder supply system.
  • the metering pump 6 allows the over a certain line length Powder extraction by suction without fluidization, so that the powder the color changer 5 without the previously required Air injection to the containers 9 can be supplied.
  • the container itself suffices, for example, with the usual shaking and possibly a slight fluidization in order to keep the flow of Ensure powder to the suction opening.
  • the invention is not based on the described embodiment with the arrangement of the unit 4 on the driving axle of the robot. Rather, it is advantageously possible at least the dosing pump 6, but also the color changer 5 in or on another movable part of a coating machine to arrange, for example with a robot or in the arm that moves the wrist. (in Fig. 2 at 1)
  • Fig. 3 shows the principle of a possible embodiment of the in 1 and 2 usable dosing pump 6. It consists essentially from a chamber 11, which is controlled by a valve 12 to a compressed air source, not shown, and another controlled valve 14 to a likewise not shown Vacuum source is connected. The exit of the chamber is over the hose 7 (FIGS. 1 and 2) connected to the atomizer 13, while the powder inlet 15 of the chamber via a valve 16 the output of the color changer is connected.
  • the compressed air and Vacuum sources serve as a pump drive.
  • the promotion and The powder coating is dosed by changing the pressure and vacuum in the chamber, for which purpose an air permeable Membrane is arranged.
  • the output is essentially defined by the chamber size.
  • Such pumps are known per se (EP-A 1 106 547).
  • the dosing pump 6 and their arrangement according to the invention have the advantage that the powder dosage is more precise than with the usual one Dosing with air injection on the stationary storage containers.
