Definitions

  • the invention relates to a method according to the preamble of claim 1 and a coating system for performing the method.
  • the spray head of rotary atomizers or the like is connected to high voltage in order to thereby generate the field which charges the sprayed coating particles between the spray head and the grounded object to be coated .
  • a coating material of relatively good conductivity such as so-called water-based paints
  • the insulation resistance via the line connecting the spray head to the paint supply system is too low if the storage system is at earth potential.
  • the entire paint supply system is grounded from the storage container to the spray head of the atomizer and the radially sprayed material is indirectly charged via the external electrodes surrounding the spray head (EP-OS 0171042).
  • EP-OS 0171042 the external electrodes surrounding the spray head
  • a separate storage container for each color, which is arranged insulated from earth and from the other containers and feeds the spray device at high voltage potential via a color changer and a connecting line .
  • the connecting line is flushed with a given color and before changing to another color with solvent (water) and dried with compressed air in order to maintain the required insulation for the container which is subsequently connected to the spraying device.
  • solvent water
  • the invention has for its object to provide a method or a coating system for performing a method that requires significantly less construction than the last-mentioned known system, and in which there is the possibility to continue the normal coating operation even with a color change without significant interruption .
  • the invention has the essential advantage that the storage container can be made smaller and simpler than in the comparable known systems and can be used in common for all selectable colors. Under certain circumstances, a simple short line or hose piece with a defined volume is sufficient as a storage container. If you work with two such reservoirs in push-pull mode, a practically non-stop coating of any size series of workpieces is possible even with a color change. The effort required is low, especially with regard to the insulation between the grounded supply system and the spray device. Another advantage is that only minimal losses of coating material have to be accepted.
  • the invention is suitable e.g. especially for the large-scale coating of automobile body shells.
  • a storage container is used, the volume of which can be adjusted and, before the coating material is filled in, is adjusted in accordance with the amount required for coating (for example a single workpiece), as a result of which the cleaning effort can be reduced.
  • a suitable storage container can consist of a metering cylinder with a displaceable piston.
  • the main needle valve HNV of the atomizer Z placed in operation at high voltage potential for example in the order of magnitude of 100 kV, is to be supplied with water paint stocks (not shown) of different colors via a color changer FW in a manner known per se.
  • the color changer FW has color valves F1, F2, F3 ... Fn for a corresponding, largely any number of n selectable colors.
  • the color changer has a valve V0 for flushing liquid and a valve PL0 for compressed air.
  • a distribution valve VV is connected to the color changer via a flushable dosing pump DP0, which is driven by a stepping motor M or the like with an insulated or isolating shaft and has a bypass valve controlled by a bypass valve.
  • a flushable dosing pump DP0 instead of the dosing pump DP0, another dosing device controlled by a flow meter can also be provided.
  • the distributor valve VV Via the distributor valve VV, the water-based paint coming from the color changer FW can be directed into one of two supply lines LVA or LVB under the control of two paint flow valves FV0.
  • the ink supply valves FV0 are arranged parallel and symmetrically to each other, and the distributor valve VV also has two correspondingly arranged return valves RF0.
  • Each of the supply lines LVA and LVB leads via a first flushing valve arrangement SP1 into a flushable, pressurizable storage container V, the output of which is connected to a changeover valve UV via a second flushing valve arrangement SP2 and a connecting line LZA or LZB.
  • the purge valve arrangement SP1 has two valves V1 and V12 for flushing liquid, two valves PL1 and PL12 for compressed air and a paint flow valve FV1.
  • the flushing device SP2 has a valve V2 for flushing liquid, a valve PL2 for compressed air, a color flow valve FV2 and a return valve RF2.
  • the circuit with the lines LVB and LZB also contains built-up and arranged flush valve arrangements with a flushable reservoir pressure container in between.
  • the switching valve UV connects these parallel circles or branches as shown via a further flushable dosing pump DP4 or the like.
  • DP4 which correspond to the dosing pump DP also, i.e. can in particular have a stepper motor with an isolating shaft and a bypass, with the main needle valve HNV of the atomizer Z.
  • the main needle valve HNV contains in addition to the main needle HN valves V4 for flushing liquid and a return valve RF4.
  • the two storage containers V shown preferably have only a capacity of the order of magnitude of the amount of lacquer required for coating a single workpiece. In the case of vehicle bodies, e.g. a content of approximately 0.8 l is sufficient.
  • the pressurizable container V is filled by the dosing pump DP0 under a predetermined pressure with a predetermined amount of paint.
  • the required fill quantity is stored in the form of data in the higher-level control system of the system, which controls the metering pump accordingly and at the same time automatically opens the valve for the desired color in the color changer FW.
  • this compulsory metering also takes into account the volume of the line sections which are also to be filled, which in the example mentioned can be of the order of 0.1 l.
  • the forced metering can also be dimensioned for a plurality of workpieces.
  • the required lines such as LVA, LVB, LZA and LZB are hoses made of insulating and water-repellent material, preferably made of plastic, such as PTFE.
  • the color changer FW and usually also the dosing pump DP0 and the distribution valve VV are constantly at ground potential, while the atomizer Z with its main needle valve HNV and usually the flushable dosing pump DP4 (with the exception of its insulated drive motor) and the changeover valve UV are constantly at high voltage.
  • the atomizer Z with its main needle valve HNV and usually the flushable dosing pump DP4 (with the exception of its insulated drive motor) and the changeover valve UV are constantly at high voltage.
  • the parallel branches connected in between with their respective storage container V on the other hand, constantly change their potential cyclically between the high and the low potential, depending on the electrical connection made by the conductive coating material to the grounded supply system and the atomizer.
  • one of the valves e.g. F1 of the color changer FW filled by the downstream metering pump DP0 of the container V of the left branch in the drawing, namely via the color flow valve FV0 of the distribution valve VV, the line LVA and the color flow valve FV1 of the flushing valve arrangement SP1.
  • the filling extends up to the color flow valve FV2 of the flushing valve arrangement SP2.
  • the ink supply valve FV0 is closed and the color changer FW rinsed.
  • solvent which can mainly consist of water in the example considered
  • the valve V0 of the color changer It washes also the dosing pump DP0 and reaches the disposal device ES via the return valve RF0 of the distributor valve VV, taking along existing paint residues via a disposal line LES.
  • the valve PL0 of the color changer which is designed as a check valve, blows air to dry the rinsed paths.
  • the insulating section formed by the line LVA between the distributor valve VV and the flushing valve arrangement SP1 must also be flushed and dried.
  • the valve V12 of the purge valve arrangement SP1 for solvents and its air valve PL12 are opened simultaneously or alternately.
  • the solvent or the air, taking the color residues remaining in the LVA line, pass through the valves FV0 and RF0 of the distribution valve VV into the disposal line LES.
  • the entire path leading from the air valve PL12 through the distributor valve VV into the disposal line must be completely blown dry by air.
  • the paint can be supplied from the pressurized (or pressurized via the air valve PL 1) container V via the switching valve UV and the dosing pump DP4 the atomizer. This is done via the color flow valve FV2 of the flushing valve arrangement SP2, the line LZA, the color flow valve FV3 of the changeover valve UV and the lines leading to the dosing pump DP4 and the main needle valve HNV.
  • the container V is under high voltage, but is isolated from the paint supply system due to the described emptying of the line LVA.
  • the coating material from the container V is initially only up to the closed main needle valve of the atomizer Z "pressed", expediently via the bypass of the dosing pump DP4.
  • This "pressure path" can lead up to or beyond the return valve RV4 of the main needle valve HNV. Only then is the main needle valve opened in this preferred mode of operation and the paint is pumped by the dosing pump DP4 into the atomizer Z for spraying.
  • the pressure in container V can be in the order of 2.5 to 4 bar, for example.
  • the atomizer can then both inside, i.e. from the switching valve UV to the main needle valve HNV, as well as outside, i.e. rinsed on the bell plate or the like. Both happens via the air valve PL3 and the solvent valve V3 of the switching valve UV.
  • the paint residues in the inner line system between the switching valve UV and the main needle valve HNV are discharged through the return valve RF4 into the disposal device ES.
  • the parallel right branch can be prepared for the coating of the next vehicle body in the manner described above.
  • the same or a different color can be selected.
  • the relevant, possibly other valve such as e.g. F2 of the color changer FW is opened and the coating material is conveyed into the right reservoir by the dosing pump DP0, which is available again at this point in the coating of a body, via the paint supply valve on the right of the distributor valve VV in the drawing, the line LVB and the right flush valve arrangement.
  • the color changer is then rinsed again in the manner described, also during the coating.
  • the insulating section formed by the line LVB between the container on the right in the drawing and the distribution valve VV can then be rinsed and then blown completely dry. How this is done has already been explained for the LVA management.
  • the coating material of the new paint can now be “pressed on” from the right container to the main needle valve HNV, the right container being placed under high voltage. Then the dosing pump DP4 pumps this coating material into the atomizer Z, which sprays it onto the next body.
  • the left-hand container V in the drawing in which the first color was, can be rinsed.
  • solvent is passed through the valve V 1 of the flush valve arrangement SP1 through the container V and via the return valve RF 2 of the flush valve arrangement SP2 into a line leading to the disposal device ES.
  • air can be blown through the container V via the valve PL 1.
  • the insulating section formed by the line LZA between the flushing valve arrangement SP2 and the changeover valve UV can be flushed and then blown dry. This is done via the valves PL2 and V2 of the flush valve assembly SP2 and the return valve RF3 of the changeover valve.
  • the existing paint residues are again supplied to the disposal device ES via a line connected to the valve RF3.
  • the first operating phase ie the connection of the left tank V to the supply system
  • the atomizer Z can be rinsed again, and during the coating of the next body the right container must be rinsed and the insulating section formed by the line LZB must be rinsed and dried.
  • a storage container with a given unchangeable volume is used in the method described above with reference to FIG. 1, the container must obviously be dimensioned so large that it is sufficient for the largest possible workpiece to be coated. In many cases, however, the coating system should be used for workpieces of different sizes, i.e. once for larger and at other times for smaller workpieces. A typical example of this is the series coating of various motor vehicle body shells. When used for smaller workpieces, the storage container only has to be partially filled with paint, while after the subsequent cyclical emptying, the entire volume is filled with solvents for cleaning the container.
  • Fig. 2 largely corresponds to that of Fig. 1, but has the advantage that the effort in solvent and time for cleaning the reservoir can be reduced to a minimum.
  • the color changer FW and the distributor valve VV are always at ground potential, while the atomizer Z with its main needle valve HNV and the changeover valve UV are constantly at high voltage.
  • the interposed parallel branches with a respective dosing cylinder DZ constantly change their potential intermittently between the high and the low potential, depending on the electrical connection made by the conductive coating material to the grounded supply system and the atomizer. Due to the alternating filling and emptying of the supply and connection lines on the inlet and outlet sides of the dosing cylinders DZ, the paint changer and the spray device are kept constantly isolated from one another.
  • the dosing cylinder DZ according to FIG. 3 consists of a cylinder vessel 1 and a piston 2 which can be displaced therein and which is arranged at the end of a piston rod 3 which is sealingly guided by an end wall of the vessel.
  • the cylinder vessel 1 In its other end wall facing away from the piston rod 3, the cylinder vessel 1 has an outlet opening 4 which leads into the flushing valve arrangement SP2 (FIG. 2).
  • the inlet of the metering cylinder DZ connected to the first flushing valve arrangement SP1 is located in the channel 5 inside the piston rod 3, which is designed as a hollow tube.
  • the channel 5 is inside the piston 2 into a connecting channel 6, which leads to an annular channel 7 which runs concentrically to the displacement axis thereof in the vicinity of the circumferential surface of the piston 2.
  • Outflow nozzles 8 fed by the ring channel 7 run in the direction shown generally towards the inner wall of the vessel with a slight inclination forward in the direction of displacement (towards the outlet opening 4) and open into the end face of the piston 2 close to the inner wall of the vessel to which they are directed.
  • an annular gap can also be provided.
  • the piston 2 can be in two parts, one part being integrally connected to the piston rod 3 and the other part fastened to it being able to contain the channels 6, 7.
  • the piston In its peripheral surface, the piston has sealing rings 9, with which it slides sealingly on the inner wall of the cylinder vessel 1, which is straight in the direction of displacement.
  • the space between the lower end face of the piston 2 in FIG. 2 and the outlet opening 4 forms the adjustable volume of ink quantity.
  • a compressed air connection 10 opens into the space on the other side of the piston, the purpose of which will be explained below.
  • a spindle drive SM (FIG. 2) connected to the piston rod 3 and having a stepper motor can be used to adjust the volume of ink quantity, which is fed by pulses which the electronic control system of the system generates before the start of coating based on the body size stored in the form of data.
  • a spindle drive instead of a spindle drive, a rack or other drive system can also be used.
  • the dosing cylinders DZ are filled, emptied and cleaned essentially in the manner described above.
  • the dosing cylinder DZ of one of the two branches is filled via the color changer FW. Because simply the previously set volume of the dosing cylinder no dosing pump is required. After rinsing and drying the color changer FW and the relevant supply line LVA or LVB, the color is removed from the dosing cylinder DZ and fed to the atomizer Z.
  • the dosing cylinder DZ should be rinsed.
  • the movement of the piston can take place up to the stop of the piston end face on the appropriately shaped end wall of the cylinder vessel 1.
  • venting the dosing cylinder when filling and cleaning can take place via one of the valves of the flushing valve arrangements SP2 leading to the disposal or the changeover valve UV or possibly also via the atomizer itself.
