Definitions

  • the invention relates to a color change valve arrangement for optional connection of an application organ of a coating system with a variety of supply lines for Coating material of different selectable colors according to the preamble of the claim.
  • Such valve arrangements in coating systems for series coating of workpieces such as motor vehicle bodies needed are u.a. from DE 198 36 604 and DE 198 46 073 known.
  • These color change valve arrangements or short color changer allow in paint shops during the paint shop a rapid change from one color to another and persist mainly of a number of controllable color valve units, along a color channel common to all colors are distributed.
  • they are in block construction of individual Modules (connection blocks, terminal strips, control heads) formed, which can be strung together, so that a variable, subsequently enlargeable or reducible Number of connections for color cables can be realized can.
  • the color valves are usually further, similar constructed valves for flushing media such as thinner liquid and pulse air provided.
  • the valve units exist turn from pin or needle valves, the valve needle pressed by a compression spring in the closed position and against their power from a pneumatically controlled piston drive be opened.
  • valve needles along the in Rule straight collecting channel juxtaposed valve units are moved in parallel planes that perpendicular to the collecting channel axis, for improvement the flow conditions but also be arranged obliquely can (DE 198 46 073, WO 02/09886).
  • color changers known for space reduction instead of the usual Straight collection channel a right angle to the longitudinal axis of the Color change block arranged spiral groove included (DE 43 39 301), which is less aerodynamic than a straighter one Collecting duct.
  • color changer of the considered here Genus by significant advantages such as dead space, good Flushability, low dead volume, small size, low weight, modular construction, small number of parts, assembly, Maintenance and repair friendliness etc. off. They have Therefore, proven in practice for a long time. 'Disadvantage is in the known color changers but their number selectable shades corresponding length in the longitudinal direction of common collection channel. As a result, the known ones are suitable Color changer relatively bad for installation in close Rooms of coating machines such as e.g. Painting robots and even worse for installation in the on these machines mounted atomizer itself, as it u.a. from those in the simultaneous registration EP ... (according to DE 103 34 412.8) may be desirable.
  • the invention is therefore based on the object, the length of the Color changer in the longitudinal direction of the valve units common Collection channel and in particular the size of the valve units down to the needle axes to a minimum, without thereby the required sealing effect against to deteriorate the valve seat pressed valve needle.
  • the invention assumes that for the safe and reliable Function of valves whose needles (with what arbitrary Pins are meant) in the closed position with a certain Minimum force due to the required sealing effect must not be fallen below, against the valve seat must be pressed.
  • the invention is based on the knowledge that by lowering this necessary minimum closing force and / or with appropriate reinforcement of the to overcome the minimum closing power available Power Possibilities of miniaturization of the valve unit in particular in a dimension transverse to the needle axis and thus open in the longitudinal direction of the collecting channel. Consequently the color changer is better than before Installation in small spaces with limited space such as e.g. in relatively slim robot arms or relatively small ones Atomizers.
  • the invention is suitable for color changer with or without Color circulation (by the known return channels) as Simple color changer or also for the formation of double color changers, the well-known common color supply lines have and with the atomizer on separate color ranges are connected.
  • Good for the formation of dual color changers are suitable e.g. particularly according to the invention flat built color change valve assemblies.

  • a expedient possibility consists in particular in the Surface of the valve seat opposite sealing surface of the Valve needle, preferably including its end face and / or the surface of the valve seat of an elastomeric To form material, so that thanks to the softer sealing materials with a relatively low contact force a significant better sealing effect is achievable than before.
  • the elastomers Surface is appropriately designed so that no undercuts or dead spaces are formed in which themselves Paint could settle, and not rinsed residue-free could become.
  • the elastomeric surface is similar the usual valve needles and valve seats appropriate shaped so that the sealing edge as close to the collection channel is and preferably at least approximately with the Inner wall is aligned (see DE 198 36 604).
  • the surfaces concerned the valve needle and the valve seat can in the in a conventional manner rectilinear parallel to each other or For example, in the described in DE 102 28 277 Way curved, wherein the valve needle is a substantially having spherical outer contour.
  • a variant of option described here is inside a e.g. made of a plastic such as UHMPE or UHMWPE (polyethylene ultra high molecular weight) needle tip for example, consisting of an elastomeric O-ring spring element to use such that an elastically yielding ("soft”) needle tip results.
  • valve needles of the paint valves a color changer adjacent to the conical tip with a Ring groove and an O-shaped therein Gasket to provide an additional seal reach (DE 198 46 073).
  • the invention has the advantage that formed by the O-shaped sealing ring Undercuts and dead spaces are avoided in which can not settle rinse off paint residues, the if later replaced, cause color defects of the coating, and that the sealing edge of the needle directly on the Can be collecting channel.
  • the closing force is preferably generated by a spring whose Force to open the valve from the pressure medium of the piston drive device must be overcome.
  • a spring with a degressive characteristic curve is another appropriate opportunity for reduction the necessary minimum closing force in it.
  • the invention is based on the finding that the largest Closing force required only in the idle state of the closed valve is, while on actuation of the valve with a the piston stroke decreasing size of the pressure to be overcome is desirable.
  • a compression spring used whose characteristic more when squeezed or less (hard or soft) sloping curved. The same applies to the use which is also possible in itself a tension spring instead of the compression spring.
  • a structurally particularly simple way of power amplification consists in the use of a piston, which at the of the pressure medium acted surface a non-circular, for example, flat, rectangular or oval Cross section has, with the short axis of this cross section should be parallel to the direction in which the valve unit miniaturized, so for example in Longitudinal direction of the collecting channel. Comparing this piston drive with the usual valve drive with a cylindrical Piston, this results in the same piston size in the direction of the short cross-sectional axis a significant greater force (pressure x piston area) and the same force a much narrower piston.
