Definitions

  • the invention relates to a painting system for applying liquid Coating material on workpieces with an automatic controllable color changer, one that can be connected to high voltage Atomizer, one between the color changer and the atomizer running supply line made of electrically insulating material, through which a pig can be moved back and forth, and with one with the Supply line connected potential isolation device for electrostatically isolating at least one to the feed line connected storage container for the coating material and of the atomizer versus the color changer.
  • Such a painting system for electrostatic coating is used in particular by motor vehicle bodies, is from DE 199 61 270 A1 known.
  • the feed lines are in use one pig each can be emptied and then form one Isolation path that a voltage flashover from the first Storage container to the color changer or from the second storage container to the first reservoir prevented.
  • the known system can be operated so that continuously from the second high-voltage reservoir coated can be what a metering conveyor in the form of a Gear pump is provided while the first reservoir in Alternation in high voltage and in earth potential is placed so that it alternately filled from the outside during the coating operation and can be emptied into the second reservoir.
  • the Loss is essentially limited to a paint volume that corresponds to the Contents of the single insulating section of the feed line corresponds.
  • a color changer 1 is connected to a ring line system 2 connected, from which different shades a - n are fed to him can be.
  • Each individual ring line is a color valve 3a in the color changer 1 assigned to 3n, through which the respective color within the Color changer 1 is released.
  • detergent valves 4a - 4n for detergent and purge air valves 5a - 5n arranged for purge air.
  • the released is released via a release valve 6 Hue fed into a feed line 7, which differs from Color changer 1 extends to an atomizer 8.
  • a first or front one Pig park station 9 which seen in the paint flow direction represents a or front end of a pig running track, which with the Feed line 7 is identical. That seen in the paint flow direction other, second end of the pig running track is also as Pig parking station 10 and is located directly on or in Atomizer 8. If coating material from the color changer 1 in fed the feed line 7, pushes the coating material a pig 11 initially located in the pig parking station 9 until it arrives at the pig parking station 10.
  • the Pig parking station 10 is designed so that the coating material can flow past or around the pig 11 and over it the atomizer valve 12 can emerge from the atomizer 8.
  • a release valve 13 and a Outlet valve 14 opened at the end of supply line 7.
  • a sensor 15 that the arrival of the pig 11 and thus recognizes the end of the pressing process.
  • the duration of the Pressing process also by measuring the amount of paint fed in or the pressing time can be controlled.
  • the atomizer 8 is one as intended High voltage potential electrostatic atomizers is and the coating material is an electrical conductive paint, e.g. B. a so-called water-based paint, must take care to be worn so that it does not have any conductivity during operation Paint-filled paint supply line 7 comes to a short circuit.
  • an electrical conductive paint e.g. B. a so-called water-based paint
  • the potential separation device 16 contains essential components a first potential isolation valve 17 and a second potential isolation valve 18 and a first storage cylinder 19 and a second Storage cylinder 20 for the coating material, both with work with a piston.
  • a gear metering pump can act.
  • a pneumatically remote controlled paint pressure regulator LDR
  • LDR paint pressure regulator
  • the potential separation device 16 is via a front connecting line 40 and a rear connecting line 41, each with a Shut-off valve 22 and 23 are provided to the supply line 7 connected.
  • the shut-off valves 22 and 23 are in immediate vicinity of the supply line 7.
  • the in the Feed line 7 coating material can thus be also into the potential separation device 16 and its storage cylinder 19 and feed 20.
  • To the rear connecting line 41 is immediately in front the shut-off valve 23 has a drain line with a drain valve 24 connected.
  • the Shut-off valves 22 and 23 of the connecting lines 40 and 41 as long opened until the potential separation device 16 is filled.
  • the dosage the filling quantity can be made with the aid of the metering element 21 become.
  • the drain valve 24 After the potential separation device 16 has been completely filled closes the drain valve 24.
  • shutoff valves 26 and 27 are front Shut-off valve 26 and a rear shut-off valve 27, which the Limit insulation section 25 and into the supply line 7 installed and designed as piggable ball valves. This means that the inside diameter of the two ball valves is exactly that Correspond to the inner diameter of the feed line 7 and thus the The pig can pass through the open shut-off valves 26 and 27.
  • the Isolation section 25 between the two shut-off valves 26 and 27 forms a bypass to the potential isolation device 16.
  • the shut-off valves are used to flush the insulating section 25 26 and 27 closed.
  • a drain valve 28 just before the rear Shut-off valve 27 is opened and via a release valve 29 immediately after the front shut-off valve 26 purge air and Detergent via a detergent valve 30 and a purge air valve 31 in the Insulated section 25 blown.
  • the release valve 29 and that Drain valve 28 are arranged so that in the insulating section 25th coating material is rinsed out without residue.
  • the coating material has been completely rinsed out of the Isolating section 25 is then blown dry by compressed air, so that it is reliably non-conductive.
  • the length of the insulation section 25 is chosen as short as possible, so that by flushing resulting paint loss is kept as low as possible. However, must the insulating section 25 be sufficiently long so that the Atomizer 8 applied high voltage reliably against earth potential is isolated.
  • the atomizer valve 12 is closed and the High voltage switched off.
  • the check valve 23 of the rear Connection line 41, the rear shut-off valve 27, the release valve 29 and the drain valve 32 are opened.
  • Dosing member 21 between the shut-off valves 22 and 23 in the Potential separation device 16 included coating amount closed shut-off valve 22 and open release valve 37 see above fed as far as possible into the empty insulating section that comes with it completely filled with coating material.
  • an on Atomizer 8 arranged detergent valve 34 in alternation with the The sliding air valve 33 also located there is opened. Thereby the paint residues remaining in the feed line 7 over a on the color changer 1 arranged drain valve 36 rinsed.
  • the system After completing these flushing processes, the system is ready for Feeding a new color from the color changer 1.
  • the required flushing time can be significantly reduced if for the Rinsing the individual pipe sections with heated detergent is used.
