Definitions

  • the invention relates to a multi-component metering with a plurality of metering valves and a coupling device for a control valve.
  • liquid mixtures such as perfumes, flavors, colors or the like, consisting of a variety of different components
  • gravimetric or volumetric dosing systems are used in practice.
  • the dosing units have up to 500 individual dosing valves.
  • the arrangement of the metering in the metering is circular, linear or freely selectable, but limited by the size of the container to be filled.
  • the control valves of the metering valves are located either directly on the individual metering valves or in a separate control cabinet.
  • the direct attachment of the control valves to the associated metering valves is often not possible due to space problems.
  • the accommodation of the control valves in a control cabinet is required in particular in systems that are subject to the special conditions of explosion protection.
  • the control valves are arranged in an explosion-proof area of the control cabinet and connected in each case with a separate electrical wiring and a complex tubing with the respective metering valve. Several hoses are combined into a bundle, whereby the clarity in the dosing is adversely affected.
  • a device for the continuous metering and mixing of liquid mixtures in various mixing containers in which a separate metering device with a metering cylinder and two associated, the metering cylinder switching control cylinders is provided for each liquid component. Due to its large space requirement, such a metering device is only suitable for use in metering systems for the production of liquid mixtures of a few components.
  • the known multi-component metering systems therefore have the disadvantage of high costs and a large installation effort. Because of the confusing installation problems occur during the maintenance and repair of the metering device. A clear visual assignment of the individual metering valves to their control valve is not reliably guaranteed.
  • the coupling device for the control valve only a single switching element for all metering valves is required because during the mixing process of the liquid mixture, the vehicle of the coupling device with the control valve belonging to the coupling piece moves sequentially to the position of the coupling counterpart, which predetermined by the recipe program metering valve is assigned, and there in the clutch position, the control valve is connected to the corresponding metering valve, so that the control valve switches the metering valve from the closed position to the delivery position.
  • the coupling piece is brought by the actuator transverse to the road with the respective coupling counterpart in coverage.
  • the guide for the vehicle of the coupling device is expediently a preferably horizontal rail having holes arranged in series along the roadway.
  • the coupling counterparts for the metering valves are arranged and on the opposite longitudinal side (terminal side) of the rail connections for cables are fixed to the holes.
  • the coupling counterparts are set directly to the arranged on the coupling side of the rail metering valves and coupled to the closure bodies of the metering valves.

  • the movable armature fixedly connected as a counterpart coupling with the closure body of the metering valve and the coil is arranged on the coupling piece.
  • the existing of parts of the coupling piece and the coupling counterpart control valve for the openable metering valve is provided by the coupling device.
  • the metering valve is switched by means of solenoid valve from the initial closed position to the delivery position by the coil current is turned on, whereby the armature is pulled to the coil and at the same time the closure body releases the discharge opening of the metering valve.
  • the armature is returned by a return spring in the closed position of the metering valve and held there, so that the closure body closes the discharge opening.
  • the armature is on the coupling side advantageously designed as a plate. In order to switch the metering valve from the closed position to the delivery position, it is sufficient if the two coupling parts abut congruently for the most part. As a result, inaccuracies in the positioning of the vehicle in the coupling counterpart of the predetermined metering valve are compensated.
  • the coupling mating coupling side is formed as a cooperating with a cavity in the coil in the coupling pin, so that in the coupling position of the coupling device armature and coil form a positive hole-pin connection.
  • the compressed air lines are saved from the rail to the metering valves.
  • the reduction in the number of laid lines contributes significantly to the clarity in the metering, as the existing lines can be assigned directly to the corresponding metering valves.
  • each coupling counterpart on the guide in particular a rail, a hole and a connection for a pressure line associated with the associated metering valve.
  • the coupling piece runs a through-line, to the input side via a connection a pressure line is connected to the control valve.
  • the hole of the guide and the opening of the passage line of the coupling piece are congruent to each other, so that a continuous connection line is made from the control valve to the associated metering valve.
  • the metering valve are designed as a pneumatically switchable from the control valve metering cylinder with connected reservoir.
  • a discharge nozzle occlusive or releasing closure body is set.
  • the control valve works as a compressed air valve, which controls the liquid delivery of the metering valve.
  • the control valve and the respective metering valve are two separate, spatially separated valves.
  • the coupling piece has a plurality of juxtaposed and / or successively arranged passage lines each having on the input side a connection for a pressure line to a control valve.
  • the coupling piece engages over a plurality of single or multi-row holes arranged in the rail, so that the passage lines in the coupling piece connect to the holes of the coupling counterparts and in each case a continuous connecting line from the control valves to the metering valves.
  • the dosages of various liquid components can be made by the successive control of the corresponding metering valves by means of the control valves, without the vehicle must be moved on. As a result, the cycle times between the individual dosages are shortened.
