Definitions
- the invention relates to a valve arrangement for the production a multi-component paint, especially in the form of a mixer for producing a multi-component water-based paint, according to the preamble of claim 1 and an operating method for such a valve arrangement according to the preamble of claim 12.
- Such multi-component paint known, for example can be arranged on the arm of a painting robot and the Multicomponent paint supplies to a nebulizer, which also attached to the arm of the painting robot.
- This known valve arrangement has a hardener supply line and a stem paint supply line on, which lead to a common output line, wherein in the hardener supply line and in the base paint supply line in each case a controllable valve is arranged.
- the known valve arrangement has a purge line which via a flush valve also in the common output line the valve assembly opens.
- the two controllable valves in the hardener feed line and in the base paint feed line opened, whereas the detergent valve is closed, so that the parent lacquer in the common output line mixes with the hardener and forms the multicomponent varnish.
- DE 1 900 518 A discloses a spraying device for liquid synthetic resins, in which in a catalyst supply line behind a catalyst valve arranged a check valve is.
- a system for changing the colors of a paint sprayer is off US 4 993 353, which proposes two color changing apparatuses to operate in a row.
- US 4 703 894 further discloses a two-component mixer, which allows one of the color reservoir and the hardener removed spray gun with the two-component mixture to supply.
- DE 102 23 498 A1 discloses a method and a system for ink supply of an electrostatic coating system with a modular potential separation unit, the at least two paint reservoirs and one container each for a detergent and for a material to be disposed of contains.
- the invention is therefore based on the object, the beginning described known valve assembly to the effect improve that chemical reaction of the solvent-based based hardener with moisture from the water rinse, the pulse air or the environment as much as possible is prevented.
- the invention comprises the general technical teaching, in Rinse with a water rinse and / or when blowing moisture-containing pulse air and / or at a longer Interrupt the hardener valve with a shut-off valve to seal off contact between the hardener and in the water scavenger, the pulse air or the ambient air to prevent moisture contained.
- the solvent-based based hardeners e.g., isocyanate

- valve needle 27 of the flushing valve 25 In an in the drawing below lying position is the valve needle 27 of the flushing valve 25, however, the transition from the Detergent supply line 24 to the chamber 11 free, so that the Detergent V2 from the detergent supply line 24 into the chamber 11 can penetrate.
- the activation of the actuator 26 takes place this pneumatically via a compressed air control line 28, the from the left in the drawing end face of the valve assembly 2 goes out and to the actuator 26 of the detergent valve 25 is performed.
- the rotary atomizer 1 still has a conventional Main valve 29, which in the output line. 5 is arranged and the delivery of the multi-component water-based paint controls, wherein the main valve 29 in turn from a pneumatic actuated actuator 30 and one of the actuator 30 mechanically driven and displaceable in the rotary atomizer 1 stored valve needle 31 is made.
- the control of the actuator 30 takes place pneumatically by another Compressed air control line 32, the left of the in the drawing lying end face of the valve assembly 2 goes out and to the actuator 30 of the main valve 29 is guided.
- the hardener valve 10 and the shut-off valve 15 are against during normal painting operation, so that the Hardener H via the hardener valve 10, the chamber 11 and the open Shut-off valve 15 enters the output line 5, where the hardener H mixes with the base varnish SL, which passes over the opened Stammlack valve 4 also in the output line 5 arrives.
- the resulting multi-component water-based paint is then corresponding to the rotary atomizer 1 the valve position of the main valve 29 applied.
- the flushing valve 20 is opened while the shut-off valve 15 and the other flushing valve 25 are closed stay.
- About the detergent supply line 19 are then alternating pulse air PL and a water-containing Spülmit tel Supplied V1, which enter the common output line 5 and these and the entire rotary atomizer 1 of Clean residues of the 2-component paint.
- the flushing agent valve 20 closed, whereupon the flushing valve 25 and the Shut-off valve 15 are opened.
- About the detergent supply line 24 then becomes an anhydrous, solvent-containing conventional rinsing agent V2 supplied into the chamber 11th penetrates and over the open shut-off valve 15 in the Output line 5 passes until the rotary atomizer 1 with the solvent-containing, anhydrous detergent V2 filled and optionally rinsed.
- Anhydrous rinse V2 prevents water-containing Detergent residues of the detergent V1 in the rotary atomizer 1 or the valve assembly 2 chemically with the hardener H react, which in extreme cases to a clogging of the hardener valve 10 and the other valves could result.
- a special feature of this embodiment is that of the parent lacquer feed line 3 via a return valve 33rd a return line 34 branches off, wherein the return valve 33rd in turn from a pneumatically actuated actuator 35 and a driven by the actuator 35 and in the valve assembly 2 slidably mounted valve needle 36 is.
- the return valve 33rd in turn from a pneumatically actuated actuator 35 and a driven by the actuator 35 and in the valve assembly 2 slidably mounted valve needle 36 is.
- the return valve 33 for the base paint SL is used for pressing and flushing the Stock paint supply line 3 when using several different ones Stammlacken SL with the same hardener H.
- the different Basecoats SL are then at an upstream and not shown color changer connected centrally and are pressed as needed to the rotary atomizer 1.
- the activation of the actuator 35 of the return valve 34th again takes place pneumatically by a compressed air control line 37th
