Description

The invention relates to a method according to the preamble of claim 1 and to a filling system according to the preamble of claim 9. Such a method and filling system are known from WO2010017888 known.

For the purposes of the invention, "containers" are in particular cans, bottles, tubes, pouches made of metal, glass and / or plastic, but also other packaging materials which are suitable for filling liquid or viscous products for pressure filling or for pressureless filling.

For the purposes of the invention, "free jet filling" is to be understood as meaning a process in which the filling material flows into the container to be filled in a free filling jet, the container with its container mouth or opening not resting against the filling element, but rather from the filling element or from a filling element there Füllgutauslass (discharge opening) is spaced.

For the purposes of the invention, "contents" are, in particular, liquid or flowable products which, in a liquid or flowable base or matrix, contain solids or solid constituents, e.g. Contain particles and / or fibers, such as fruit, fruit or vegetable juices with fruit, fruit or vegetable pieces or fibers.

The term "essentially" in the context of the invention means deviations from the exact value by +/- 10%, preferably by +/- 5%, and / or deviations in the form of changes that are insignificant for the function.

It is known to determine the liquid volume of products filled in containers by measuring the volume flow using flow meters, for example by measuring with electromagnetic flowmeters (MIDs), which have no moving functional elements and are therefore characterized by a high robustness.

For products containing solids or solid components, the measurement of the liquid volume or the volume flow of the respective container prepares supplied filling material but often problems or it comes here to erroneous measurements in particular by investing in the measurement of solids on the inner surfaces of the flow meter and / or especially in magnetic inductive flow meters flowing through this flowmeter product due to the solids has a highly fluctuating conductivity and this leads to incorrect measurements. This also applies if products containing such solids or solids are supplied to the respective container to be filled in at least two phases or components, namely in the form of a solids-free or substantially solids-free main component and a dosed, the solids or solid components in higher concentration, but still flowable additional component.

The WO 2011044972 A2 was on 21 April 2011 published and is therefore relevant only to the novelty of the invention.

The object of the invention is to provide a method which allows high-accuracy and reliable volume and / or quantity-controlled filling of containers with solids or solids containing products. To solve this problem, a method according to claim 1 is formed. A filling system for volume and / or quantity-controlled filling of containers is the subject of claim 9.

In the invention, the filling of the containers with the solids or solid components containing product or product takes place in that this contents in the form of at least one solids-free or substantially solids-free main component and separated therefrom with a containing the solids or solid components but still flowable additive component in the respective Container is introduced. The metering or addition, ie the determination of the filling volume of the additional component takes place indirectly in the inventive method, by measuring that volume of the main component, which is displaced from the introduced into a storage or metering volume of the additional component, with a flow meter , which in this case flows through exclusively by the at least one solids-free or substantially solids-free main component. Despite the possibility of accurate dosage of at least one additional component Impairment or incorrect measurements in the determination of the volume of this additional component by solids or solid components avoided.

Magnetic inductive flow meters (MIDs) which are particularly inexpensive, robust and can be used everywhere or almost anywhere are used as flow meters in the invention, provided that the measurement of the volume flow and thus the volume (time integral of the volume flow) of liquid products with sufficient electrical conductivity.

Further developments, advantages and applications of the invention will become apparent from the following description of exemplary embodiments and from the figures. Also, the content of the claims is made an integral part of the description.

similar representations as Figures 1 and 2 in a further embodiment of the filling system according to the invention.

That in the Figures 1 and 2 generally designated 1 filling system used for filling containers, which are exemplified as bottles 2, with a liquid product, which consists of the component K1 (main component) and the component K2 (additional component), of which the component K1 is a liquid, ie no or substantially no solids or solids containing component, such as fruit, fruit or Vegetable juice and the component K2 are still a liquid or flowable, but solids or solid components, such as fruit, fruit or vegetable fibers or components (also pulp) in higher concentration containing component.

The two components K1 and K2 are successively introduced into the respective bottle in a filling process in the manner described in more detail below, wherein the mixing of these components takes place essentially only in the respective bottle 2.

In principle, the introduction of the components K1 and K2 into the respective bottle 2 takes place such that in at least one filling phase of the filling process the required filling volume of the component K1 and in at least one filling phase the required filling volume of the component K2 are introduced into the bottle 2 to be filled.

The filling system 1 comprises in a known manner a filling element 3, in the housing 4, a liquid channel 5 is provided which forms a discharge opening 6 at the bottom of the housing 4 and at its this discharge opening 6 remote upper region via a connection 7 to the lower end a metering or product line 8 is connected. The filling element 3 is part of a filling machine of rotating design and for this purpose together with a plurality of similar filling elements 3 on the circumference of a vertical machine axis rotatably driven rotor 9 is provided on which u.a. a boiler 10 for the component K1, an annular channel 11 for the component K2 and an annular channel 12 are provided, in each case for all filling elements 3 of the filling machine together.

The annular channel 12 is part of a hot circulation described below in more detail for the component K1, with which not only the component K1 but also all functional components of the filling system 1 carrying this component are kept at an elevated temperature required for hot sterile filling.

During the filling operation, the boiler 10 is partially filled with the component K1 partially controlled, specifically to form a occupied by the component K1 liquid space 10.1 and one filled for example with an inert gas chamber 10.2 above the liquid level of the component K1.

Via a control valve device or via a first control valve 13 of this device, the upper end of the product line 8 is connected to the liquid space 10.1 of the boiler 1 connected, via a supply line 14 via a second control valve 15 of the control valve means is the upper end of the product line eighth controlled with the component K2 leading annular channel 11 connectable. The product line 8 and the control valves 13 and 15 are provided independently for each filling element 3 of the filling machine.

In the interior of the liquid channel 5 is located between the port 7 and the discharge opening 6 operable by an actuator 16 liquid valve 17, with the volume and / or quantity controlled delivery of the contents in the respective bottle 2, the connection between the terminal 7 and the discharge opening 6 controlled at the beginning of each filling process and is closed at the end of the filling process, in response to electrical measurement signals of a first flow meter 18 and a second flow meter 19. The two flow meters 18 and 19, which are, for example, electromagnetic flowmeters (MIDs), respectively measure and record the volume flow of the component K1 through the product line 8 and are spatially separated from each other in the product line 8 so arranged that the flow meter 18 in the region of the upper end of the product line 8, ie in the flow direction to the control valve Following e 13 and 15 and the flow meter 19 is located in the lower region of the product line 8 in the flow direction in front of the terminal 7. Between the two flow meters 18 and 19, the product line 8 forms a in the Figures 1 and 2 helically illustrated product line section 8.1, which serves as a storage or dosing and whose volume is at least equal to the largest, to be introduced into the respective bottle 2 in a process step of the filling process filling volume of the second component K2, but less than that in the respective bottle 2 during the filling process to be introduced filling volume of the first component K1.

In the event that the filling element 3 is provided for hot filling, in the filling element 3 or in the housing 4 further, a, a control valve 20 having liquid connection 21 is provided which connects the liquid channel 5 controlled with the annular channel 12, u.a. such that even with the liquid valve 17 closed, i. before introduction and / or after completion of the respective filling process and with open control valves 13 and 20, a flow connection from the liquid space 10.1 through the product line 8, through the liquid channel 5 and through the opened liquid connection 21 into the annular channel 12 and from there via a non-illustrated a heater having connection back into the boiler 10 for the hot circulation of the component K1 consists.

The respective bottle 2 is arranged for free jet filling with its bottle opening 2.1 at a distance below the discharge opening 6, with its bottle axis coaxially with the vertical Füllelementachse FA. In the illustrated embodiment is used to hold the respective bottle 2 a each filling element 3 associated and provided on the rotor 9 container carrier 22 to which the bottle 2 is held with a bottle mouth flange hanging.

• Während des Füllbetriebes sind der Flüssigkeitskanal 5 zumindest in Strömungsrichtung vor dem Flüssigkeitsventil 17, der Anschluss 7 sowie die Produktleitung 8 vollständig mit dem Füllgut gefüllt, und zwar vor Beginn des jeweiligen Füllprozesses bevorzugt ausschließlich mit der Komponente K1. Weiterhin befindet sich das Steuerventil 20 während des jeweiligen Füllprozesses im geschlossenen Zustand und wird erst nach Beendigung des jeweiligen Füllprozesses für den Heißumlauf geöffnet.

The operation of the filling system 1 can be described as follows:

• During the filling operation, the liquid channel 5, at least in the flow direction in front of the liquid valve 17, the connection 7 and the product line 8 are completely filled with the filling material, specifically before the start of the respective filling process exclusively with the component K1. Furthermore, the control valve 20 is in the closed state during the respective filling process and is opened only after completion of the respective filling process for the hot circulation.

At the beginning of each filling process, the liquid valve 17 and the control valve 15 are opened in a first or preceding process step with closed control valves 13 and 20, so that the component K2 is introduced from the annular channel 11 into the product line 8 or into the product line section 8.1, while displacing part of the hitherto in the product line 8 located component K1 via the opened liquid valve 17 into the bottle 2. The thereby displaced by the component K2 from the product line 8 volume of the component K1 corresponds to the introduced into the product line 8 volume of Component K2 and is detected with the, in this process step exclusively by the component K1 through flow meter 19.

If the volume measured with the flow meter 19 corresponds to the required filling volume of the component K2 to be introduced into the respective bottle 1, the control valve 15 is closed. Thus, with the flow meter 19, the partial volume of the first component K1 introduced into the respective bottle 2 in the preceding method step, but at the same time also that introduced into the product line 8 or into the product line section 8.1, i. metered volume of the component K2 determined.

In a second or subsequent process step, with the liquid valve 17 still open and closed control valves 15 and 20, the control valve 13 is opened, so that then rinsing the product line 18, the product line section 8.1, the terminal 7 and the liquid channel 5 with the component K1 the entire, initially located in this product line 8, ie metered volume of the component K2 is introduced into the bottle 2 and the product line 18, the product line section 8.1, the terminal 7 and the liquid channel 5 are in turn exclusively and completely filled with the component K1. The case of the respective bottle 2 inflowing volume of the component K1 is determined first with the lower flow meter 19 and then later with the upper flow meter 18, but in any case so that for the quantitative and / or volume control of the filling process only the Measuring signal of that flow meter 18 or 19 is used, which is currently not flowed through by the component K2 or by the portion or remainder of the component K2 containing contents.

Taking into account the predetermined by the construction and thus known volumes of the product line 8, the terminal 7 and the liquid channel 5, taking into account the volume of the component K1, the In the first process step has already been introduced into the bottle 2, and possibly also taking into account further filling parameters, such as temperature of the components K1 and K2, etc., the closing of the liquid valve 17 and the control valve 13 to terminate the filling process then takes place when the component K1 is also introduced with the required filling volume in the respective bottle 2. After completion of each filling process, the control valve 20 is opened again for the renewed hot circulation when the liquid valve 17 is closed.

Since the filling system 1, the control valve 20 is closed during the entire filling process, u.a. effectively prevents the component K2 or its components from entering the annular channel 12 and thus into the hot circulation.

The FIGS. 3 and 4 show in a representation similar to the Figures 1 and 2 a filling system 1a, which differs from the filling system 1 substantially only in that in the in the FIGS. 3 and 4 No flow meter are provided with 8a product line, but for each filling element 3 of the filling system 1 a and the respective filling machine separately a flow meter 18a in the connecting line 14 and a flow meter 19a in the liquid connection 21 are arranged. Otherwise, the filling system 1a corresponds to the filling system 1, so that those components and / or components which correspond at least to their function forth components and / or components of the filling system 1, in the FIGS. 3 and 4 with the same reference numerals as in the Figures 1 and 2 are designated.

The volume of the product line 8a and of the connection 7 is greater than the volume of the component K2, which is introduced into the respective bottle 2 in a method step, but smaller than the volume of the component K1 to be introduced into the respective bottle 2.

• Am Beginn des Füllprozesses wird in einem ersten oder vorausgehenden Verfahrensschritt bei geschlossenem Flüssigkeitsventil 17, bei geschlossenem Steuerventil 13 und bei geöffnetem Steuerventil 20 das Steuerventil 15 geöffnet, sodass die Komponente K2 aus dem Ringkanal 11 über das Steuerventil 15 in die Produktleitung 8a gelangt und hierbei die bis dahin in der Produktleitung 8a vorhandene Komponente K1 zumindest teilweise über den Anschluss 7, den Flüssigkeitskanal 11 und die Flüssigkeitsverbindung 21 in den Ringkanal 12 verdrängt. Das dabei die Flüssigkeitsverbindung 21 durchströmende Volumen der verdrängten Komponente K1 entspricht dem der Produktleitung 8a zufließenden Volumen der Komponente K2 und wird mit dem Durchflussmesser 19a erfasst. Sobald das mit dem Durchflussmesser 19a erfasste Volumen dem in die Flasche 2 einzubringenden Füllvolumen der Komponente K2 entspricht, werden das Steuerventil 15 und das Steuerventil 20 geschlossen. Das erforderliche Füllvolumen der Komponente K2 befindet sich dann in der Produktleitung 8a sowie eventuell teilweise auch im Anschluss 7.

With the filling system 1a, for example, the following filling method is possible, wherein at the beginning of each filling process, the product line 8a, the connection 7 and the liquid channel 5 in the flow direction in front of the liquid valve 17 are completely filled with the component K1:

• At the beginning of the filling process, the control valve 15 is opened in a first or previous process step with the liquid valve 17 closed, closed control valve 13 and open control valve 20 so that the component K2 passes from the annular channel 11 via the control valve 15 in the product line 8a and in this case the until then present in the product line 8a existing component K1 at least partially via the terminal 7, the liquid passage 11 and the liquid connection 21 in the annular channel 12 displaced. The volume of the displaced component K1 flowing through the liquid connection 21 corresponds to the volume of the component K2 flowing into the product line 8a and is detected by the flow meter 19a. As soon as the volume detected by the flow meter 19a corresponds to the filling volume of the component K2 to be introduced into the bottle 2, the control valve 15 and the control valve 20 are closed. The required filling volume of the component K2 is then located in the product line 8a and possibly also partially in the connection 7.

In a second or subsequent process step, after closing the control valve 20 by opening the liquid valve 17 and the control valve 13, the component K1 is introduced from the boiler 10 into the product line 8a. As a result, the volume of the component K2 present there is first introduced into the bottle 2 via the liquid connection comprising the product line 8a, the connection 7 and the liquid channel 5, and this liquid connection is completely flushed with the component K1, so that in turn it is filled exclusively with the component K1 is. The volume of the component K1 flowing into the product line 8a from the boiler 10 is detected by the flow meter 18a. Taking into account the predetermined by the construction and thus known volume of fluid communication between the control valve 13 and the discharge port 6, ie taking into account the bekanten volumes of the product line 8a, the terminal 7 and the liquid channel 5 and possibly also taking into account further Füllparametern, such as Temperature of the components K1 and K2, etc., the closing of the liquid valve 17 with the actuator 16 and thus the completion of the filling process then takes place, although the component K1 is introduced into the bottle 2 with the required filling volume. At the end of each filling process, when the control valve 13 is still open, the control valve 20 for the hot circulation of the component K1 is reopened.

In the filling system 1a, the filling volume of the component K2 to be introduced into the respective bottle 2 is likewise not determined directly but indirectly by the volume of the component K1 displaced by this component and detected by the flow meters 18a and 19a.

In the filling system 1 a, the liquid valve 17 during the metering of the component K2, i. closed during the introduction of this component in the product channel 8a. The metering of the component K2 can therefore, in a filling machine having this type of filling system, already take place in the angular range of the rotational movement of the rotor 9 between a container outlet and a container inlet of the filling machine, i. in the so-called "loss angle" of the rotational movement of the rotor 9, i. before the bottle 2 to be filled is transferred to the container inlet to the respective filling station formed by the filling element 3 and the container carrier 22. As a result, the usable for the entire filling process angular range of rotation of the rotor 9 is substantially increased and recovered process time for the filling process to a considerable extent, so that given machine dimensions (diameter of the rotor 9) u.a. Also, a significant increase in the performance of the filling machine (number of filled bottles 2 per unit time) is achieved.

The inventive construction generally erroneous measurements of the flow meter 18, 19 and 18a, 19a are avoided in particular by solid components in the filling. With the construction according to the invention, furthermore, a high dosing accuracy is achieved when introducing the components K1 and K2 into the bottles 2 and a high accuracy of the total filling volume introduced into the bottles 2 in each case.

The invention has been described above by embodiments. It is understood that numerous changes and modifications are possible. So is above always the volume or volume of the speech. Of course, these terms are also equivalent to "amount" or "fill quantity" enforce.

In the foregoing, the present invention has been explained essentially in terms of such filling elements 3, which were intended or suitable for hot filling of products. It goes without saying, however, that other, not intended for hot filling of products or filling materials filling elements for the application of the present invention are suitable, so that the present invention or the application of this invention defies the selected embodiments not for hot filling suitable filling elements 3 is limited

Furthermore, it was assumed that the component K2 is introduced into the metering or storage space formed by the product line section 8.1 or by the product line 8a and possibly also partially by the connection 7 only in one method step of the entire filling process and in a subsequent method step from this is applied with the component K1 in the bottle 2. Of course, in particular with correspondingly large-volume bottles 2 or other large-volume containers, it is possible to repeat these aforementioned process steps twice or repeatedly in the respective filling process. In any case, however, the measurement of the filling volume of the component K2 takes place indirectly by measuring the volume of the component K1 displaced by this component, so that the control of the filling process can be effected exclusively by signals of flow meters 18/19 or 18a / 19a, which are currently only available from the component K1 or a medium to be flowed through which contains the component K2 at most in a proportion which is not relevant to the measurement accuracy and / or measurement reliability.
