To implement the method of operating the installation during the time interval when the feeding tank 16 is isolated from the spray device 1 by emptying the power supply connecting pipe 12.13,
    feed tank 16 injects coating material through a feed pipeline 12,13 using a coating method from a supply system at low potential or ground potential. Then, the feed tank 16 containing the coating material is electrically isolated from the supply system by emptying the supply conduit 12.13. 2 sec. and 19 hp ff, 3 ill.
    The invention relates to a plant for electrostatic coating and to a method for its operation.
    The purpose of the invention is to reduce costs and reduce changeover time.
    Fig. 1 shows a schematic of an installation for electrostatic coating with forced metering of a rotary atomizer or other electrostatic atomizing device with a water-based varnish or similarly to an electrically conductive coating material; Fig. 2 shows an embodiment of the installation of Fig. 1; FIG. 3 shows a reasonable form for carrying out a metering cylinder serving as a supply tank for the installation of FIG. 2.
    The installation contains a spraying device 1 with a main needle valve 2, a low-potential or ground potential sleep system; / coating material (not shown). The installation contains a device for 3 chamfer shifts with color valves 41.4a, 4z..4p for an arbitrary number of colors that are appropriate for a wide range. Further, the ink changer 3 has a valve 5 for washing liquid and a valve 6 for compressed air. To the device 3 paint changes through the washable dosing device 7 in pump aide driven by a stepper motor 8 or the like with an insulated or insulating shaft and having a bypass valve controlled by-pass 9, a control valve 10 is connected. Instead of the metering pump 1, another metering device may also be provided that is controlled by the flow meter.
    Through the control valve 10, the water-based varnish coming from the device 3 for changing colors can be directed to one of the common to all colors insulating supply lines 12 or 13, when controlling the two valves 11 for the direct stroke of paint. The valves 11 for the direct stroke of the ink are parallel and symmetrical to each other, and the control valve 10 further has two respectively arranged return valves 14. Each of the supply and insulating pipes 12 and 13 common to all colors is connected through a flush controlled valve device 15c with a supply tank 16 whose output is via a second controllable valve device 17 and
    Isolation connecting pipe 18 or 19 respectively is connected to switching valve 20.
    The flush controlled valve device 15 has two valves 21 and 22
    respectively, for flushing fluid, two rivets 23 and 24, respectively, for compressed air, as well as valve 25 for forward running for paint. Wash controlled valve device 17 has a valve 26
    for flushing fluid, valve 27 for compressed air, valve 28 for direct stroke for paint and non-return valve 29,
    A circuit with an insulating supply conduit 13 and an insulating connecting conduit 19 also contains precisely designed and located flush controlled valve devices with a flushing pressure feed tank located between them.
    Switching valve 20 connects these circuits or branches parallel to each other through an additional metering device in the form of a washed metering pump 30, which may coincide with
    The metering pump 7, therefore, in particular, have a stepper motor with an insulated shaft and a bypass with the main needle valve 2 of the spraying device 1. The main needle valve 2, in addition to the main needle 31, contains valves 32 for flushing liquid and a return valve 33.
    Both supply tanks 16 have a capacity that is preferably only a capacity of the order of the amount of lacquer that is required for coating a single grinding. In the case of car bodies, for example, a volume of approximately 0.8 liters may be sufficient. The pressure-loaded feed tank 16 is filled with a metering pump 7 at a given pressure with a predetermined amount of varnish. The required filling volume is remembered in the form of data in the higher-level installation control system, respectively, controlling the dosing pump and at the same time also automatically opening the valve for the desired paint in the 3 ink change device. In this forced dosing, in addition to the amount of varnish required for the workpiece, the volume of the correspondingly filled pipeline sections is also taken into account, which in the mentioned example may be in the order of 6.1 liters. In cases where other, in particular, smaller blanks are to be coated, a forced dosing volume can also be assigned to several blanks.
    The insulating pipes 12 and 13 of the power supply and the soldering connecting pipes 18 and 19 are hoses made of an insulating and, if possible, water-repellent material, mainly of synthetic material, such as, for example, Teflon.
    When the installation is in operation, the device 3 changes ink and, as a rule, together with it also the metering pump 7 and the control valve 10 are permanently connected to the ground potential, while the spray device 1 with its main needle valve 2 and, as a rule, is flushed The metering pump 30 (except for its insulated drive motor) and switching valve 20 are permanently connected to high voltage. As a variation of this example, it is also possible to implement the described cyclic isolation between the supply tank 16 and the dispensing device 1 (insulating connecting pipes 18 and 19) in the pipeline between the switching valve 20 or the dosing pump 30 on the one hand and the spray device 1 on the other hand . Parallel branches connected between them with their respective supply capacity 16, for example, constantly replace their potential between high and low potential depending on the electrical conductive material produced for applying the electrical connection to the given supply system and the spraying device.
    The method of operation of the electrostatic coating plant is explained by describing various successively or partially also occurring simultaneously working phases.
    First, through one of the valves, for example, through the valve 4 of the paint-changing device, the supply tank 16 of the left branch is filled with the included additional metering pump 7, namely the valve
    11 a straight stroke for the paint of the dispensing valve 10, an insulating supply line 12 of the power supply and a valve 25 of the forward stroke for the paint of the flush controlled valve device 15. Filling up to the valve 28 of the forward stroke for the paint of the flush controlled valve device 17 occurs.
    After filling the supply tank 16, close the valve 11 for the direct stroke for the paint and wash the device 3 paint changes. For this purpose, a solvent (which in the example under consideration can consist essentially of water) is directed through the valve 5 of the ink replacement device to the ink replacement device. The solvent, the metering pump 7 is also washed, and through the return valve 14 of the distribution valve 10, the existing paint residues are carried away through the waste disposal line 34 into the waste disposal unit 35. At the same time and / or thereafter, through the valve 6 of the ink changer, made according to the invention as a return valve, air is blown in to dry the washed out paths.
    In particular, after filling the tank 16, the insulated section formed by pipe 12 between the control valve 10 and the flush controlled valve device 15 must also be flushed out. To this end, simultaneously open or alternate the valve 22 of the flush controlled solvent valve device 15, respectively valve 24. Solvent, respectively air, entrains remaining in the pipeline
    12 paint drips through valves
    11 and the dispensing valve 10 to conduit 34 for waste disposal. After stopping the supply of the solvent by closing the valve 22, the entire path leading from the air valve 24 through the distribution valve 10 to the waste disposal line must be completely dried by blowing with air.
    Now the paint from the pressurized or submerged pressure through the air valve 23 of the supply tank 16 through the switching valve 20 and the metering pump 30 can be applied to the spray device 1. This is done through the valve 28 of the forward stroke for the paint flushing valve device 17. - the wire 18, the valve 36 of the switching valve 20 and the piping leading to the metering pump 30 and to the main needle valve 2. The supply tank 16 is under high voltage, but due to the described support The line 12 is insulated from the paint supply system.
    Advantageously, the material for applying the coating from the supply tank 16 is first passed under pressure only up to the closed main needle valve of the spraying device 1, namely due to the expediency of the metering pump 30 through the bypass of the metering pump 30. This pressure transmission path can pass up to the return valve 33 of the main needle valve 2 or by him.
    Only then does the main needle valve open and the paint is pumped over by the metering pump 30 for spraying with a sawing device 1. With this, the pressure in the supply tank can be, for example, in the order of 2.5 to 4 bar.
    Thereafter, the spray device may be washed internally, i.e. from the switching valve 20 to the main needle valve 2, and from the outside, i e.
    Both are through the air valve 37 and the valve 38 to dissolve the switching valve 20. The remaining paint in the internal piping system between the switching valve 20 and the main needle valve 2 is discharged through the return valve 33 to the waste disposal device 35.
    While the spray device 1 is supplied from the supply tank 16 of the left branch, parallel to the right branch, the branch can be prepared in the manner described for coating the next
    car body. Depending on the need, the same or a different paint can be chosen for this. Consequently, under certain circumstances, a different valve, such as the valve 42 of the paint changer 3, and the material for coating through the metering pump 7, which is currently available for coating the body , through the right valve 11 of the receiving stroke for the paint of the distribution valve 10, the pipe 13 and the right flushing valve device 15 are fed into the right supply tank 16. 5 Similarly, during the application of the coating, the device 3 changes again in the described manner paints.
    With the spray device 2 operating, it can then be flushed and after it is completely dried by blowing air through the insulated section 13 formed by pipe 13 between the right 16 supply tank 16 and the control valve 10. How this 5 happens is explained with regard to pipe 12
    After the application of the coating is finished, the body considered at the beginning can now be passed under pressure from 0 of the right supply tank 16 to the main needle valve 2 of a new color coating material, with the right supply tank being connected to high voltage, then the metering pump 5 30 pumps this material for coating the spray device 1, which sprays this material onto the next body.
    In view of expediency, during the time that the coating material passes from the right supply tank 16 to the main needle valve 2 of the spraying device, the supply tank 16, in which the right paint was located, is left flushed in Fig. 1. For the first stage, the solvent through the valve 21 of the flush controlled valve device 15 through the feed tank 16 and through the return valve 29 of the flush valve 0 of the controlled valve device 15 is directed to the pipeline leading to the device 35 for waste disposal. Simultaneously or alternately, air 5 can be blown through valve 25 through feed tank 16.
    Similarly, during the supply of paint from the right supply tank 16 to the main needle valve, the insulating section between the flushing valve device 17 and the switching valve 20 formed by pipeline 18 is dried by air blowing the valves 27 and 26 of the flush valve device 17 and the check valve 39 of the switching valve. Existing paint residues are again conducted through a pipeline connected to valve 39 to waste disposal device 35.
    As soon as the pipe 18 is dried, it is possible to restart the first working phase, hence connecting the left supply tank 16 to the supply system. It goes without saying that at the same time after the completion of coating on the second body, the spray device 1 can be washed again and the supply tank 16 should be washed right during the coating on the next body and the insulated section formed by pipeline 19 should be washed and dried.
    These processes continue cyclically from body to body and can be controlled without any problems with a sequence of inclusions ensuring perfect separation of potentials.
    If a feed tank 16 is used with a given constant volume (FIG. 1), the feed tank 16 must obviously be of such dimensions that it is sufficient for the largest possible correspondingly coated workpiece (s). However, in many cases, an installation for electrostatic coating should be used for blanks of different sizes, therefore, once for larger and another time for smaller blanks.
    A typical example of this is serial coating of various unprocessed car bodies. Consequently, for smaller workpieces, in accordance with the cyclically adjacent emptying for cleaning the tank, the entire volume is filled with solvents. As a result, in particular, more solvent than necessary is used in the cyclic filling and selection of a relatively small amount of coating material, which is undesirable because of the associated environmental pollution (harmful effects) and, in addition, cleaning - because of the longer filling time, it takes correspondingly longer time, which is wasted for the implementation of the serial coating process.
    The installation depicted in FIG. 2 largely corresponds to the installation in
    according to figure 1; but it has the advantage that the consumption of solvent and the cleaning of the feed tank can be reduced to a minimum. 5 The device 3 paint changes and the control valve 10 are permanently connected to the ground potential when working, while the spray device 1 with its main needle valve 2 and switching
    0, valve 20 is permanently connected to high voltage. Parallel branches connected between them with a corresponding metering cylinder 40, which, on the contrary, in their function changes their potential.
    5 in a clockwise manner between high and low potential depending on the electrical connection coating produced by the conductive material to the grounded supply system and the spray device. By alternately filling and emptying the supply and connecting pipelines on the input and output sides of the metering cylinders 40, the device 3 paint changes
    5 and the spray device are permanently kept isolated from each other.
    Before the start of the coating process, the volume of both metering cylinders
    0 must be set according to the amount of paint required, i. in accordance with the size of the surface of the covered body. For this purpose, the metering cylinder 40 (FIG. 3) consists of a cylindrical container
    41 and a piston 42 being moved therein, located at the end of the piston of the rod 43, which is hermetically guided through the end wall of the container. At its remote from the rod 43 piston 42 another end
    In the wall 0, the cylindrical container 41 has an outlet 44 leading to the flushing valve device 17 (FIG. 2). The inlet of the metering cylinder 40, connected to the first flushing valve device 5 by means of the tube 15. is located in the channel 45 inside the rod 43 of the piston 42, made in the form of a hollow tube.
    The channel 45 enters inside the piston 42 into the connecting channel 46, leading to the annular channel 47, passing around in the vicinity of the circumferential surface of the piston 42 concentric with respect to its axis of movement. The jet nozzles 43 fed by the annular channel 47 are directed in the direction of the inner wall of the container with a slight inclination forward in the direction of movement (to the outlet 44) and enter the end surface of the piston 42 close to the inner wall of the container to which they are directed. Instead of a large number of nozzles
    48 may also include an annular gap. The piston 42 can consist of two parts, and one part can be connected integrally with the rod 43 of the piston 42, s fixed another part can be made with channels 46 and 47. On the circumference of the piston there are sealing rings 49, which it slides tightly along a straight line in the direction of movement of the inner core of the cylindrical container 41. The volume between the lower (FIG. 2) end surface of the piston 42 and the outlet 44 forms an adjustable volume for paint. In the bay on the other side of the piston, connection 50 for compressed air enters.
    To adjust the volume of paint, a screw drive 51 (Fig. 2) connected to the rod 43 of the piston 42 can be used with a stepper motor fed by pulses produced by the electronic control system of the installation before applying coatings based on the size of the body laid down by a series of data.
    Instead of a screw drive, a rack or other drive system may also be used.
    . The filling, emptying and cleaning of the metering cylinders 40 are carried out in a generally described manner. Consequently, first, through the device 3, the color changes and the metering cylinders 40 fill one of the two branches. Since the previously adjusted volume of the metering cylinder can be completely filled, the metering pump is not required. After washing and drying the device 3 paint changers and the supply line 12 or 13, which is related here, the paint is taken from the metering cylinder 40 and fed to the spray device 1.
    Thereafter, the dosing cylinder 40 should be flushed. For this purpose, it would be sufficient to direct the solvent through the flush valve device t5 through the volume adjusted between the piston 42 and the outlet 44. However, this solvent is preferably sprayed from the reactive nozzles 48 to further save the solvent. the inner wall of the cylindrical container 41, while at the same time the piston 42 containing the nozzles moves in the direction of the outlet 44. At the same time, the paint stuck to the wall is washed off External viewer
    a piston 42 having attachment rings 49 and is fed in the direction of the outlet 44.
    The use of a piston can be carried out up to the stop against the end surface of the piston in the end wall of cylindrical tank 41, which is designed accordingly. To accelerate this movement, cleaning can be done with compressed air, acting through the compressed air fixture 50 on the end surface of the piston 42 from the drive side. Control valves 52 for driving compressed air are shown in
    5 figure 2. Thereafter, the piston 42 is returned back to the position defined by the control system. The change in the design of the drive for the piston rod 42 with the screw drive 51 required for this method is not pictorial and the tie is the subject of an invented shadow.
    The possibilities are also different in terms of pumping out the dosing cylinder during filling and cleaning.
    5 Pumping may be performed through one of the valves leading to the waste disposal device, flushing valve devices 17 or switching valve 29, or perhaps also through the spray device itself.
