Definitions

  • the invention relates to a method and a system for supplying material consumers, in particular for the ink supply of coating devices, according to the preamble of the independent claims.
  • material consumers in particular for the ink supply of coating devices, according to the preamble of the independent claims.
  • it is the series coating of workpieces such as vehicle bodies with possibly electrically conductive coating material, in which the first group of materials can be formed by the different standard or series colors and the additional material group by different special colors.
  • the nebulizers of the vehicle body coating systems are known to be fed from loop lines to which they are connected by stubs and color changers which may be located within the spray booth at or near the painting robots or other coating machines.
  • the stub lines are expediently designed as pig tracks in modern coating systems ( DE 101 31 562 . DE 101 57 966 etc.).
  • special colors which are pumped from separate color containers located in the color mixing chamber outside the booth directly through their own stub lines to the atomizer removal points, which may be designed as color changers ( DE 196 32 325 , and the generic DE 100 06 310 ).
  • spur lines are pigging lines, so that, for example, in a conventional manner filled a predetermined amount of paint in the line and promoted in the so-called pushout operation to the sampling or not sprayed paint from the line in the so-called reflow operation in the Paint tank can be backfelt.
  • the pig pipes required for this purpose take up a great deal of space, and since hitherto a separate piggyback route to the removal point is required for each special color, considerable expense for the pigging lines and their pigging stations also results for a larger number of special colors.
  • this effort by the large space requirement in the paint mixing chamber and in the valve cabinets and the limited space available for the laying of pigging hoses, the number of possible special shades is undesirable limited.
  • the invention has for its object to reduce in processes and systems for material supply in particular of the type described above required for a given number of selectable additional materials overhead and space requirements of the pig lines and to increase the efficiency of existing gemold lines.
  • FIG. 1 Scheme shown can form single or additional color supply systems for special colors, for example in a paint shop for the series coating of vehicle bodies.
  • A1, A2 and An denote a number n of color containers for different colors, which are each connected via a pump P to a color distributor FA formed by a valve device. At least the two containers A1 and A2 and in practice only a few further containers are connected to the paint distributor FA, but the total number n per se is arbitrary. The larger the number n, the fewer pigging distances are required.
  • each of these central channels can be connected at a pig source station MQ11 to the input of a common line ML11 which leads to the removal point E1 at which the pig target station MZ11 of the line ML11 is located.
  • the line ML11 can lead into a central channel Za or into another channel Zb, which can lead to one or more atomizers, which are to be supplied from the containers A1, A2 or An via the common line ML11 common to the respective spot colors ,
  • the removal point E1 is similar to the color distributor FA designed as a valve unit and can in particular a usual in supply systems of the type considered connected to Ring effetsmakersssysteme color changer for standard or series colors with the optionally usable, separately flushable central channels Za and Zb upstream of the color distributor FA on the gemgled line ML11 or on the central channels Za or Zb can be connected in parallel.
  • the paint distributor FA expediently one or more further pigging lines each with a gemold line such as ML12 and their source and destination stations MQ12, MZ12 connected to connect the color distributor FA with one or more other sampling points such as E2 to which additional atomizers are connected.
  • the removal points E1, E2, etc. are located on the manual and / or mechanical, optionally electrostatic, painting zones following one another in the usual way along a painting booth.
  • the pig-pig stations of the lines leading to not shown further sampling points are denoted by MQ13, MQ14 and MQ1m, where m can be any number.
  • the removal points E1, E2 etc. can be located outside or in the spray booth, for example on a robot arm or on or in the vicinity of other painting machines, while the paint distributor FA is always arranged outside the booth in the example considered here.
  • each removal point such as E1 and E2
  • further color distributors likewise supplied in each case by individual color supply systems, can be connected in accordance with FA.
  • the molten line ML21 is connected to the removal point E1 at the further pig destination station MZ21, whose pig source station MQ21 is in the color distributor FB is located.
  • the color distributor FB can be identical to the color distributor FA and thus also contain central channels connected to at least two to n individual color supply systems, each with a container B1, B2, Bn and associated pump P.
  • the second color distributor FB is also connected to the removal point E2 via the gemged line ML22 with source and destination stations MQ22 and MZ22.
  • the containers B1, B2, Bn may contain different colors than the containers connected to the paint distributor FA, but may u. U. in containers of different color distribution also be the same colors.
  • One advantage of the arrangement shown is, inter alia, that, for example, during the supply of the removal point E1 from the color distributor FA already provided a special color for the other color distributor FB and from this even up to the removal point E1 can be pressed, so this for the subsequent coating with a new material without loss of time can be prepared.
  • Fig. 2 the valve scheme of one of the color distributors such as FA or FB is shown, which may include a pig feeder station such as MQ11 with, for example, three or two pigs MP and MR as shown, to which the common line ML11 leading to the take-off point E1 is connected.
  • the pigs are mechanically positioned by a cylinder unit QZY.
  • the mentioned further source stations MQ12 to MQ1m are in Fig. 2 not shown.
  • valves for detergent and pulsed air are shown for rinsing the paint distributor.
  • the dashed lines represent the e.g. pneumatic control lines of the valves.
  • this material is pumped by manual or automatic control with the pump P into the central channel Z1 of the paint distributor FA, which first opens with the valves QFa and QFM open and with the return valve QRFM (FIG. Fig. 2 ) is filled. After this pressing of the existing pump, central channel and return pump circuit, the return valve QRFM is closed, whereupon the color material between the pigs MP and MR through the line ML11 is promoted to the discharge point E1 for pressing the pig track, so that there for delivery the atomizer is ready.
  • the paint delivery between pigs possibly with pushout through the rear pig MP is known per se and therefore need not be described in detail.
  • the line ML11 and its pig stations can be rinsed separately via the valves provided so that they are immediately available again for repressurization via another central channel Z2 or Zn, even if in the pump circuit of the central channel Z1 still Color is located.
  • the pump circuit consisting of pump P, the central channel such as Z1 and the associated feedback is also purged.
  • the single supply systems can be operated independently under manual or automatic control. For example, while one system is pressed, the other system may be in the paint or rinse state.
  • both the individual supply systems including the central channels such as Z1, Z2 and Zn as well as the pig tracks formed by the lines such as ML11 can each be independently rinsed and filled with material, i. Irrespective of the rinsing or filling of the respective other elements, there are significant advantages, in particular the least possible loss of time during a color or material change.
  • the invention is not limited to the paint supply described, but suitable for any other material supply systems with pig tracks.
