Definitions

  • the invention relates to a method and a system for the supply of material consumers, especially for 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 optionally electrically conductive coating material, in which the first material group by the different Standard or series colors and the additional material group can be formed by different special colors.
  • the atomizers of the coating systems for vehicle bodies known from ring lines fed with them via stubs and color changers connected inside the spray booth at or in near the painting robots or other coating machines can be located.
  • the stubs are in modern Coating plants expediently designed as pigging lines (DE 101 31 562, DE 101 57 966, etc.).
  • the invention is based on the object in methods and Material supply systems, in particular those described above Type that for a given number of selectable ones additional materials required effort and space requirements the livestock lines and the degree of utilization of the to increase the number of existing mutilated lines.
  • the invention results over previous systems a significant reduction in the number of pig tubing required and pig stations each by at least 50%. Accordingly also reduces the space requirement of paint supply systems in the color mixing room and the valve cabinets. This has significant cost advantages, especially as additional Advantages such as simplification of layout and process control and shorter commissioning times. On the other hand in comparison with previous systems at approximately the same Effort corresponding to many additional individual supply systems will be realized. Other benefits include minimizing the Pressure losses and the required quantities of paint.
  • the scheme illustrated in FIG. 1 may be single or auxiliary color supply systems for special colors e.g. in a paint shop for the serial coating of vehicle bodies form.
  • A1, A2 and An is a number n of color containers for different colors, which each have a pump P to a color distributor formed by a valve device FA are connected. It's at least the two Container A1 and A2 and in practice only a few more Container connected to the paint distributor FA, but is the Total number n in itself arbitrary. The larger the number n, the fewer pigging distances than before are required.
  • About controlled Valves can each of these central channels at a pig pig station MQ11 to the input of a mutilated line ML11 connected to the sampling point E1 leads, at the pig destination station MZ11 the line ML11 located.
  • the line ML11 in open a central channel Za or into another channel Zb, which can lead to one or more atomizers coming out the containers A1, A2 or An on the respective spot colors common common line ML11 are supplied should.
  • the removal point E1 is similar to the color distributor FA formed as a valve unit and can in particular a usual in supply systems of the type considered Color changers connected to loop power supply systems for standard or standard colors with the optional, contain separately flushable central channels Za and Zb, the color distributor FA on the gemmed line ML11 upstream or parallel to the central channels Za or Zb can be.
  • one or more further pig tracks with one each coiled line like ML12 and its source and destination stations MQ12, MZ12 connected to the paint distributor FA with connect to one or more additional outlets such as E2, are connected to the other atomizer.
  • additional outlets such as E2
  • the pig swell stations to not shown other outlets leading lines are with MQ13, MQ14 and MQ1m, where m is any one Number can be.
  • the sampling points E1, E2, etc. can be depending on the system, outside or in the spray booth, for example, on a robotic arm or at or near other paint machines, while the paint distributor FA at the example considered here always outside the cabin is arranged.
  • each sampling point such as E1 and E2
  • Color distributor be connected according to FA.
  • Example shown is to the sampling point E1 at the another pig destination station MZ21 the gemlechtte line ML21 connected, their pig source MQ21 is in the paint distributor FB is located.
  • the color distributor FB can the color distributor FA equal and therefore also with at least two to n individual color supply systems, each with a container B1, B2, Bn and associated pump P include associated central channels.
  • the second color distributor FB via the mixed line ML22 with source and destination stations MQ22 and MZ22 are also connected to the withdrawal point E2.
  • the Container B1, B2, Bn may contain other colors than those the paint distributor FA connected container, but u. U.
  • An advantage of the illustrated arrangement consists i.a. in that, for example, during the supply the removal point E1 from the paint distributor FA already a special color for the other color distributor FB provided and from here to the exit point E1 can be pressed, so this for the subsequent coating prepared with a new material without losing time can be.
  • valve scheme is one of the color distributors such as FA or FB pictured using a pig feeder station like MQ11 e.g. contain three or as shown two pigs MP and MR can, to those leading to the exit point E1 gemlchte Line ML11 is connected.
  • the newts become mechanical positioned by a cylinder unit QZY.
  • the mentioned Further source stations MQ12 to MQ1m are shown in FIG. 2 not shown.
  • valves for detergent and pulsed air shown for rinsing the paint distributor.
  • the dashed Lines represent the e.g. pneumatic control lines the valves.
  • this material is through manual or automatic control with the pump P in the Central channel Z1 of the paint distributor FA pumped, the first with open valves QFa and QFM and with open recirculation valve QRFM (Fig. 2) is filled. After this pressing of the pump circuit, central channel and return pump circuit the return valve QRFM is closed, whereupon for pressing the pig track the color material between the Piglets MP and MR through the line ML11 into the sampling point E1 is promoted, so that there for delivery to 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 via the dedicated valves separately be rinsed, so that they immediately return to the new pressing via another central channel Z2 or Zn available stand, even if in the pump circuit of the central channel Z1 is still color.
  • the central channel such as Z1 and the associated feedback flushed existing pump circuit.
  • the single supply systems can be under manual or automatic control operated independently of each other. Thus, while e.g. one system is pressed, the other can be System are in the paint or rinse state.
  • the invention is not limited to the paint supply described limited, but for any other material supply systems suitable with pig tracks.
