Definitions

  • the present invention relates to a device and a method for filling a container with a filling product which has a base liquid and at least one dosage component.
  • the device and the method are used, for example, in a beverage filling system for filling multi-component beverages, such as soft drinks, juices or carbonated filling products.
  • the desired components can be dosed and filled individually via separate dosing stations, as is the case, for example, from the US 2008/0271809 A1 emerges.
  • the use of separate dosing stations for a large number of components leads to a complex system structure and process flow, since the filling of each container is divided into several separate dosing / filling stations at which the container must be positioned for the respective dosing times.
  • the components can be brought together in a common filling valve, see for example EP 0 775 668 A1 and WO 2009/114121 A1 .
  • a component to be added to a base fluid is metered in front of the filling valve outlet, with the desired amount, for example, by measuring the volume using a flow meter ( EP 0 775 668 A1 ) or by another volumetric dispensing technology ( WO 2009/114121 A1 ), for example by means of a metering piston and / or a diaphragm pump.
  • High dosing accuracy can be achieved by measuring with the aid of a flow meter. This measures the volume to be dosed or the mass to be dosed and closes a shut-off valve in the dosing line when a threshold value is reached.
  • Other volumetric dosing methods such as the use of pumps or time / pressure filling, often have greater uncertainties and tend to be more sensitive to changes in the dosing medium, for example changes in pressure, temperature or composition. Frequent calibration, especially when changing the dosage medium, is the result.
  • a gravimetric measurement of the dosages is hardly feasible due to the large differences between the dosage weight for very small quantities ( ⁇ l) and the container weight.
  • the technologies outlined above are characterized by the fact that the components are mixed at a later point in time, i.e. either during or just before filling.
  • An advantage of the late addition of components in contrast to the likewise common industrial mixing of large quantities and later filling, is that the carry-over of intense aromatic substances, which migrate in seals, for example, and cannot be completely removed from the seals by cleaning, is avoided can. If the components are transported separately from one another up to the container mouth and the dosage remains drip-free, the carryover of components or their flavoring substances can essentially be ruled out.
  • the technical problems described above have led to a further development of the dosing / filling process, for example from the EP 2 272 790 A1 and DE 10 2009 049 583 A1 emerges.
  • the components of the filling product are dosed directly during filling by means of a flow meter and fed into the container to be filled together, with a main component being displaced backwards by the added component during the dosing.
  • the displaced volume of the main component is determined by means of the flow meter, and thus the volume of the metered component is also known and controllable.
  • the main component together with the added component is completely flushed out of the filling valve into the container, whereby the total filling quantity can be determined with the same flow meter.
  • the filling quantities and also the added component quantities can be redefined. This enables highly flexible filling of individualized beverages without changeover times.
  • the dosing range can be influenced both by the available dosing time and by the volume flow of the medium to be dosed. Since each flow meter is below the specific If the measurement limit, ie below a design-related minimum speed, does not show any flow and the maximum speed is specified by the squared pressure loss, the volume flow can only be changed within limits via an inlet pressure control or a proportional valve. With the selection of the nominal widths of the lines, instruments and valves, a dosing range is determined.
  • the maximum possible dosing amount is limited by the maximum amount of time available for dosing.
  • the minimum possible dosing time is technically limited by the reaction time of the flow meter, the dosing valve and the control.
  • the dosing amount can only be influenced via the dosing time.
  • the flow can also be regulated using a control valve and a flow meter.
  • the flow can be regulated for long dosing times, which is why the dosing range in this case is significantly larger than for short dosing times.
  • One object of the invention is to provide an improved device and an improved method for filling a container with a filling product that has a base liquid and at least one dosage component, preferably in a beverage filling system, in particular to improve dosage flexibility and / or enlarge the dosage range .
  • the device according to the invention is designed to fill a container with a filling product from a base liquid and at least one dosage component.
  • the filling product is accordingly a multi-component filling product made up of at least two components, one of the components being referred to herein as the "base liquid" for linguistic differentiation and preferably functioning as the main component.

  • the flow meter preferably works without contact.
  • the flow meter is preferably arranged in such a way that only the base liquid flows through it, ie any metered-in dosage components (described below) do not reach the flow meter. This means that the media properties on the flow meter do not change, and the line system is not contaminated by different fluids in these areas.
  • the device also has at least one dosage branch of the baseline, which is set up to introduce a dosage component into the dosing chamber of the baseline.
  • the dosing chamber thus serves to mix one or more dosing components into the base liquid and, in the simplest case, can be a line section of the base line.
  • the metering branch preferably has a metering reservoir which provides the metering component, a metering line that is fluidly connected to it, and a metering valve that brings the metering line into fluid connection with the metering chamber in a switchable manner.
  • the device further comprises at least one branch line with a line that brings the base reservoir into fluid connection with the dosing chamber of the base line via a valve, which is preferably designed as a shut-off valve, a flow meter that is arranged and set up on the line between the base reservoir and the valve is to determine the amount of fluid passing through the flow meter of the secondary line in the line, as well as a metering chamber which is arranged between the flow meter of the secondary line and the valve.

  • the device also has at least one metering branch of the secondary line, which is set up to introduce a dosage component into the metering chamber of the secondary line.
  • the dosing space of the secondary line thus serves, like the dosing space of the base line, to mix one or more dosage components into the base liquid and, in the simplest case, can be a line section of the secondary line.
  • the dosage branch of the secondary line preferably has one Dosage reservoir of the dosage branch of the secondary line, which provides the dosage component, a fluid-connected dosage line of the dosage branch of the secondary line and a dosage valve of the dosage branch of the secondary line, which brings the dosage line of the dosage branch of the secondary line into fluid connection with the dosing chamber of the secondary line in a switchable manner.
  • the device presented above for filling a container with a multi-component filling product made from a base liquid and at least one dosage component provides various technical contributions and advantages over conventional concepts:
  • the complete filling of the container with several components at a single filling position simplifies the handling of the container.
  • no container has to be under the filling valve during the dosing phase, since the dosing is not carried out during filling but in the dosing rooms.
  • the time for dosing can be used synergistically for transporting the container.
  • the concept presented here can thus be used both for linear indexing machines with one or more filling stations and for rotary machines. In the case of rotary machines, the containers can leave the carousel again after only a small angle of rotation.
  • any relief time can be used synergistically for the dosing phase of the subsequent container.
  • the mechanical engineering effort to implement the device is comparatively low, since the line system consists of pipes or hose lines with a few valves and only one single flow meter per line can be realized. No complicated geometries have to be built in, which means that the device is easy to clean and maintain. The risk of constipation is low.
  • the device is also suitable for metering highly viscous fluids. Carry-over of intense aromatic substances, which migrate into seals, for example, and cannot be removed from the seals by cleaning, is minimized, as the lines are only brought together shortly before the filling valve and the filling products from the secondary lines are only added to the flowing flow of the filling during filling Baseline to be initiated.

  • the device allows particularly precise, individualized dosing in a wide dosing range, since the baseline, the secondary line or a combination of both lines can be used depending on the range in which the desired dose is located.
  • a control device can be provided which not only regulates the metering of the metering component (s) into the metering rooms, but also determines which lines or which combination of lines can be used to meter the desired dosage amount most precisely and / or efficiently.
  • the different dosage regimes of the base and secondary line (s) can be implemented through different nominal widths or nominal sizes of the components involved.
  • the dosing space of the baseline preferably has a different, preferably larger, internal volume than the dosing space of the secondary line.

  • the line cross-sections of the two metering chambers and / or flow meters and / or line sections upstream of the flow meters can differ.
  • downstream and upstream refer to the filling direction, i.e. the direction in which the filling product flows when the metering spaces are emptied for filling the container.
  • the flow meter of the baseline and / or the flow meter of the secondary line is preferably set up to measure the amount of fluid passing or flowing through in the filling direction and / or to determine the direction opposite to the filling direction.

  • the device 1 By designing the nominal widths of the dosing chambers 23, 33, 43 to the desired dosing quantities and flow rates, precise dosing and optimal flushing with the base liquid can be achieved.
  • the device 1 also allows precise, individualized metering in an extremely wide metering range, since the small and very small quantities that are difficult to meter are outsourced in secondary lines 30, 40 that have been optimized for this purpose.
  • the control device can now determine which line or which combination of lines can best produce the desired filling product.
  • the duration of the dosing phase specifies the maximum dosing time available for a dosing component in the event that the other dosing components of the corresponding line do not have to be dosed. Likewise, no container 2 is necessary under the filling valve 11 during the dosing phase. The dosing phase can thus be used synergistically for transporting the container.
  • Another embodiment takes into account the fact that the reaction times between the flow rate detection by means of the flow meters 22, 32, 42 and the switching of the metering valves 24c, 25c, 34c, 35c, 44c, 45c, in particular the fluctuations in the response times, also determine the accuracy of the metered amount.
  • pneumatic valves are predominantly used for applications that come into contact with the product. However, these tend to have the technical disadvantage of longer reaction times compared to magnetically driven valves and can thus lead to a reduction in the dosage accuracy.
  • FIG. 2 is a schematic representation of such a device 1 according to a further embodiment.
  • a metering valve 27, 37, 47 is located immediately downstream of the flow meters 22, 32, 42.
  • the metering valves 27, 37, 47 are preferably magnetically switchable in order to optimize their reaction time.
  • the metering valves 27, 37, 47 react very quickly to a magnetic drive and can be designed both as pure shut-off valves, in particular for short metering times, and as shut-off and control valves, in particular for longer metering times. If the metering valves 27, 37, 47 are also installed and set up in such a way that only the basic liquid, for example water, flows through them, the requirements for hygiene and rinsing behavior are lower than for the filling valve 11 and the valves 36, 46 of the secondary lines 30 , 40, through which the dosage components also flow.
  • the device 1 and the method for producing a multicomponent filling product from a base liquid and at least one dosage component mixed therein and filling the filling product according to the exemplary embodiments presented herein provide various technical contributions and advantages over conventional concepts:
  • the complete filling of the container 2 in a single position simplifies the handling of the container 2.
  • no container 2 has to be under the filling valve 11 during the dosing phase, since the dosing is not carried out during filling but in the dosing rooms 23, 33, 43.
  • the time for dosing can be used synergistically for transporting the container.
  • the concept presented here can thus be used both for linear indexing machines with one or more filling stations and for rotary machines.
  • the containers 2 can leave the carousel again after only a small angle of rotation.
  • any relief time can be used synergistically for the dosing phase of the subsequent container 2.
  • the flow meters 22, 32, 42 and any associated metering valves 27, 37, 47 are always only flowed through by the base liquid, i.e. in most cases water. This means that the media properties do not change and the line system is not contaminated by different fluids in these areas.
  • the mechanical engineering outlay for realizing the device 1 is low, since the line system can be realized by pipes or hose lines with a few valves and only a single flow meter per line. Complicated geometries do not have to be built in, as a result of which the device 1 is easy to clean and maintain. The risk of constipation is low.
  • the device 1 is also suitable for metering highly viscous fluids. A carry-over of intense aromas that migrate, for example, in seals and not through cleaning can be removed from the seals is minimized since the lines are only brought together shortly before the filling valve 11 and the filling products from the secondary lines 30, 40 are also only introduced into the flowing flow of the baseline 20 during filling.
