  • the pressure inlet of each of the storage containers 1, 1, 1, 1, ...., and/or the fluid component outlets of each of the storage containers 1, 1, 1, 1, ...., and/or the inlets or inlet valves of the dosing head 3 are capable of being controlled, preferably capable of being controlled electronically, by an electronic control unit 6.
  • Said electronic control unit 6 may be any electronic control unit a skilled person knows for controlling the operation of a laboratory scale plant, pilot plant scale plant or industrial scale plant electronically.
  • Examples of such electronic control units are usual computers which may be capable of storing all data needed for the control of the operation of the multi-component dosing plant and emit signals in accordance with such data which signals serve to actuate (e. g. open or close) valves, start volume flows of fluid components and control volume amounts, weight amounts drawn from storage containers 1 and dosed into the vessels provided for subsequent steps, for example mixing steps and application steps of the final mixture obtained.
  • said electronic control unit 6 is capable of storing, and using for electronic control of the plant, stored data for the composition of a plurality of mixtures of fluid components.
  • data may be useful for dosing repeatedly the same relative amounts of the fluid components available for a specific mixture or "recipe", and a storage thereof could contribute not only to a rapid, exact and reliable dosing of a plurality of fluid components, but could also make it possible to dose a plurality of fluid components for a specific mixture of said fluid components on demand or just in time.
  • a paint composition for vehicles or vehicle parts could be prepared, in an amount needed for applying said paint on a predetermined amount of vehicle parts in the same quality and colour tone, at a time calculated previously for delivery to the place of application within a large vehicle manufacturing plant just in time when the parts to be painted arrive at the paint spray application chamber.
  • powders (as the fluid components) for the application of a powder paint onto metallic parts could be dosed from a multiplicity of components and mixed so as to be prepared just in time for the application.
  • said stored data for the composition of a plurality of mixtures of fluid components are recipe data of such mixtures, as explained above for the case of paints for vehicle parts.
  • the control of the overall multi-component dosing plant of the invention by said electronic control unit 6 may be performed at one of several points within the multi-component dosing plant or may be performed at more than one, e. g. two or even more of several points within the dosing plant.
  • the control may be a continuous one at all points or may be a successive one at successive points within the multi-component dosing plant. Specific examples may be the following:
  • an electronic control by the control unit, may be performed (ii) at the outlet side of the storage containers 1, 1, 1, 1, ..., or at the inlet side of the dosing head 3.
  • the electronic control step may be a step of electronically controlling the volume flow of a single fluid component or of two fluid components or of a plurality of fluid components by actuating, via the electronic control, the valve on the outlet side of the storage container(s) 1 and/or at the inlet side of the dosing head 3, thereby allowing a predetermined volume flow of one or several or a plurality of said fluid components from the storage containner(s) 1 to the dosing head 3.
  • valves may be single-stage valves or multiple-stage valves. They may release the fluid component(s) in question (i. e. those the valves of which were actuated by the electronic control) through several different cross-sections, thus making a rapid, exact and reliable dosing via the dosing head 3 possible. Particularly, small amounts of fluid components can be dosed in an exact manner reliably.
  • the control signal may be a signal from stored data (e. g. a certain recipe of a paint mixture, pharmaceutical mixture, cosmetic mixture etc.) or may be a signal resulting from a final control of the volume flow having passed the valve or arriving at the mixing vessel 4.
  • the desired plurality of fluid components is fed from the dosing head 3, via the volume stream c 2, into a fluid mixture container 4.
  • the fluid mixture container 4 is capable of providing, by a thorough mixing step, a mixture of said plurality of fluid components, more preferably provides a homogeneous mixture of said plurality of clued components.
  • a mixture may be obtained by suitable mixing means which are known per se to a skilled person in this field, as for example, high-speed mixers, vortex mixers, etc..
  • the invention also relates to a process for dosing a plurality of fluid components into a mixture of such components, said process comprising providing a multi-component dosing plant according to the above detailed description, providing said plurality of fluid components in the storage containers of said plant, applying a pressure to said storage containers allowing a feeding of said plurality of components from said containers to the dosing head and from the dosing head to the fluid mixture container of said plant, wherein the amount of feeding of each of said plurality of components of said mixture is electronically controlled by the electronic control unit.
  • the invention also relates to a process for mixing a plurality of fluid components into a homogeneous mixture of such components, said process comprising providing a multi-component dosing plant according to the above detailed description, providing said plurality of fluid components in the storage containers of said plant, applying a pressure to said storage containers allowing a feeding of said plurality of components from said containers to the dosing head and from the dosing head to the fluid mixture container of said plant, and subjecting said mixture of the plurality of fluid components to a mixing step, wherein the amount of feeding of each of said plurality of components of said mixture is electronically controlled by the electronic control unit.
  • the electronic control is exerted on the basis of data stored in the electronic control unit. More preferably, the electronic control is exerted on the basis of recipe data of the mixture of said plurality of fluid components stored in the electronic control unit.
  • the electronic control is exerted on the basis of data obtainable from metering control means, preferably on the basis of data obtainable from a metering control means selected from the group consisting of a volume metering control means and/or a weight measuring control means; or wherein the electronic control is exerted on the basis of data obtainable from a means controlling the result of the process of mixing the plurality of components, preferably on the basis of data obtainable from a means controlling a physical parameter of the mixture of said plurality of components.
  • Typical examples thereof are the viscosity of a polymer resulting from the step of dosing the components of the polymer in a suitable ratio; the tone of dye, paint or ink resulting from the step of dosing the fluid components of the dye, paint or ink; the insoluble additive particle content in a heterogeneous mixture or suspension; the effective agent concentration in a pharmaceutical or cosmetic poly-component mixture; etc.). Also measurements of an increasing concentration of a component resulting from a chemical reaction of the fluid components appropriately dosed or measurements of a decreasing concentration of an fluid component educt employed at the starting point of a reaction may be suitable.
  • the multi-component dosing plant for dosing a plurality of fluid components from their storage containers into a vessel for a mixture of said fluid components has the following advantages:
  • Air incorporated into the fluid components and remaining fluid component amounts in the containers are reduced to a minimum.
  • the storage containers 1, particular cartridges, may be changed easily, allowing a clean, reliable and standardized working with the storage containers 1.
  • the number of components (storage containers/cartridges) which may be included into the plant for the dosing step of said plurality of fluid components can be varied widely, thereby allowing a shaping of the plant in accordance to the requirements of the specific dosing task.
  • a dosing of fluid components of (substantially) all viscosities and broadly varying in their viscosities in one dosing operation may be performed.
  • the arrangement of the storage containers 1 /cartridges in a row or in a circular arrangement allows even a large number of contained to be combined in one multi-component dosing plant of the invention.
