Definitions
- the invention relates to a device for painting Objects with different colors, in circular shape Guided color lines, each associated with a color are available, with a spray gun, one Paint supply line, which is a Lackierstoff für between the circular color guide and the Produces spray gun or its nozzle, and optionally one between the circular color guides and the FarbzuWORK founded color changer, through the one color line each with the ink supply line is connectable, wherein a displacement body for cleaning the Ink supply line in Lackierlactic puzzle the Ink supply line is movable.
- a painting device with the features of the preamble of claim 1 is known from US Patent 5,221,047 known.
- the displacer is used for expressing the color in the paint supply line in Lackierflußcardi moved to the spray gun side end, there by means a discharge device from the paint supply line taken and a separate line to a Entrance mechanism returned. At this time too Bridging is a plurality of displacers intended. A return from in the paint supply line color is not back to the paint line intended. But that is taken for granted, from JP 07 171 451 A known.
- the present invention is based on the previously known painting the task, the Color return from the stubby-like Ink supply line with displacers back to a respective circular color guide still more effective.
- the Color feedback by introducing a flowable medium, which is preferably a gas, such as compressed air, or it can also be a liquid solvent, to support.
- the liquid medium acts like a Stamp printing on the paint in the feed line and ensures thirty to fifty percent more effective return of color. It became namely found that alone from the known Color return device in the form of a gear pump on the Paint supply line exerted suction pressure with the distance from the pump decreases sharply and that on the walls of the Lead to adhere to paint that is not recycled, but in a subsequent flushing together with the flushing medium is discarded. By doing so when returning of paint, the pressurized medium in Return direction is initiated in the ink supply, could have color recovery rates of eighty percent and be reached about it.
- the feeder a valve includes, which on its color side dead space free to the Ink supply line connects.
- the flexible, yielding deformable displacement provided by the over the feeding device inflowing medium in the Ink supply in the return direction and movable during then rinse the ink feed line back in Direction of the spray gun is moved back.
- the Recovery rate can be increased to 95% and more since by moving the compliant displacer in Return direction, the line inside wall quasi wiped becomes.
- the diameter of the displacer corresponds in the undeformed state essentially the Conductor inner diameter or is slightly larger than this.
- the Displacer in a rest position, preferably in one Mold recess in the paint feed line in the area of Dead space-free valve connection of the supply line.
- the valve of the feed device for the flowable medium is opened, the displacer from the Mold recess under the effect of under pressure standing streamable medium in the light Cross-sectional area of the ink supply line pressed and in Return direction moves.
- a Stop device provided for the displacer, which a kind of stop or limitation for the displacement body forms.
- the stop device is in a particularly simple and easy therefore advantageously preferably one Cross-sectional constriction formed in the paint supply.
- a sensor for Recognition of the displacer provided in Area of the stop device, in particular in Return direction before the stop device. This sensor interacts with a control of the paint shop. If the sensor detects that the displacement body in his End position in the area of the stop device has arrived, so the return process is completed and a rinsing of the Ink supply line can be initiated.
- the displacement body comprises an inductive detectable signal body, e.g. a metallic, in particular spherical core.
- FIG. 1 shows a schematic representation of a device for painting objects with different colors.
- the colors are over circular color lines 2, by a merely indicated ink supply room 4 go out and return to this, to the Lackier worn introduced.
- the painting facility includes a color changer 6 associated with each of Color cables 2 is selectively connectable. From the color changer 6 starting a Farbzumoltechnisch 8 is provided, which a Lackierstoff für between the color changer. 6 and a spray gun 10 and a nozzle 12 of the Spray gun 10 produces. Furthermore are different Compressed air supply provided, with a Compressed air line 14 opens into the color changer 6 and a further compressed air line 16 leads to the spray gun 10 and the so-called spray air for atomizing or dusting the In the spraying mode, add ink to the spray gun 10.
- a compressed air line 18 extends as Part of a feeder 20 for under pressure standing flowable medium (compressed air) to the Farbzuthetechnisch 8 and opens via a valve 21 in the Ink supply line 8.
- one of the shut-off valves is between a respective color line 2 and the color changer. 6 open, so that in the circular guided Color line prevailing pressure over the color changer 6 spreads in the supply line 8. Because this pressure to Operating the spray gun is sufficient, does not need another pump to be used and one in the Farbzu900 effet für provided gear pump 22 is over bypassed a bypass line 24.
- the gear pump 22 in Lackier Wegtechnisch below a pneumatically controllable color pressure regulator 26 provided by an electrically operated 3/2-way valve or proportional valve 28 is driven and to keep constant a predefinable, to each related color of coordinated pressure is used.
- the Color pressure regulator 26 is further configured to be in two flow directions can be flowed through.
- the gun holder 30 includes a Limit switch 32, which is connected to a not shown Control signal "gun in holder" reports. In This position is the spray gun 10 in the area of action a trigger device cooperating with the controller 34.
- the controller receives the gun in holder signal receives, so the bypass line 24 at the gear pump 22 closed, and the gear pump 22 is called Color return device 36 is driven so that it Direction to the color changer 6 promotes. Now about one Directional control valve 38 in the compressed air line 18 compressed air on a Valve 21 given.
- the valve 21 is a Diaphragm valve, which in case of pressure on the Compressed air line 18 opens against the force of a spring, so that a pressure medium connection to the ink supply 8 will be produced.
- a from the figure 2 apparent, yielding deformable displacement body 40 acted upon by the compressed air and in the paint supply line 8 in the return direction, i. towards the Color changer 6 moves.
- the displacement body 40 acts in a way as a stamp and presses in the Farbzu réelletechnisch 8 standing color column to the suction side of Gear pump 22.
- the gear pump 22 then promotes the color opposite to in the circular color lines. 2 Pending pressure in the respective color line 2 back. In this case, the displacement body 40 slides against the inside the FarbzuDOM effet 8 and cleans it out, so to speak.
- the displacer 40 finally strikes against a Stop device 42 in the form of a constriction 44 in the Ink supply 8 on.
- a sensor 46 for detecting the displacer 40 intended.
- the sensor 46 works inductively and reports when it is passed by the displacer body 40, a corresponding signal to the controller. Thereupon becomes the return process ended. Almost the entire color, the between the valve 21 and the color pressure regulator 26 and the stop device 42 for the displacement body 40th was returned to recycling. It will now by alternately opening a valve in one more not mentioned solvent line 48 and in the beginning mentioned compressed air line 14 initiated a flushing process.
- FIG. 2 shows the spray gun 10, wherein the Feed device 20 cut for the compressed air is shown.
- the compressed air line 18 opens into a Transverse hole 50, which in a metallic block 52 is formed and with a pressure chamber 54 of the valve 20th connected is.
- the directional control valve shown in Figure 1 38 is opened, so compressed air is below about 6 to 8 bar in the pressure chamber 54.
- This will be a circumferential clamped diaphragm 56 against a spring preload 58 deflected.
- one with the membrane 56th connected valve needle 60 lifted off its sealing seat 62, such that a flow connection between the pressure chamber 54 and the ink supply pipe 8 is manufactured.
- the seal seat 62 defines an opening that is free of dead space in one Mold recess 64 of the ink supply 8 opens. These Mold recess 64 also forms a rest position for the Displacer 40. So if - as just described - the valve needle 60 is lifted from the sealing seat 62, so will the displacer 40 from the mold recess 64 out in presses the ink supply 8 and wanders up to the stopper 42, wherein the displacer 40, the in the paint supply 8 located color column for Suction side of the Zahradpumpe 22 pushes in front of him.
