Das Füllsystem 1 umfasst u.a. Füllelemente 3 sowie Flaschen- oder Behälterträger 4 unterhalb jedes Füllelementes 3 zum hängenden Halten der jeweiligen Flasche 2 an einem am Flaschenhals ausgebildeten Flansch 2.1 in der Weise, dass die Flaschenmündung 2.2 einem von einer Gassperre 5 gebildeten Abgabebereich des Füllelementes 3 beabstandet gegenüber liegt. Eine Vielzahl von Füllelementen 3 und Behälterträgern 4 ist am Umfang eines um eine vertikale Maschinenachse umlaufend antreibbaren Rotors 6 vorgesehen.The generally designated 1 in the figures filling system is part of a filling machine, such as a filling machine of rotating design for Freistahlfüllen of bottles 2 with a hot liquid product (free-jet hot-filling). The filling system 1 includes, inter alia, filling elements 3 and bottle or container carrier 4 below each filling element 3 for holding the respective bottle 2 hanging on a flange 2.1 formed on the bottle neck in such a way that the bottle mouth 2.2 spaced from a gas barrier 5 dispensing region of the filling element 3 is opposite. A variety of Filling elements 3 and container carriers 4 is provided on the circumference of a rotatable about a vertical machine axis rotor 6.

Im Gehäuse 7 jedes Füllelementes 3 ist ein Flüssigkeitskanal 8 für das flüssige Füllgut vorgesehen, und zwar mit einem durch eine Betätigungseinrichtung 9 steuerbaren Flüssigkeitsventil 10, welches im Wesentlichen von einem mit einem Ventilsitz zusammenwirkenden Ventilkörper 11 gebildet ist. Das Flüssigkeitsventil 10 bzw. dessen Ventilkörper 11 sind in der Figur 1 in der geschlossenen Stellung dargestellt, so dass der Flüssigkeitskanal 8 in diesem Betriebszustand in zwei getrennte Teilabschnitte 8.1 und 8.2 unterteilt ist, von denen der obere Teilabschnitt 8.1 über eine einen Durchflussmesser 12 aufweisende Leitung 13 mit einem Kessel 14 verbunden ist. Der Kessel 14 ist für sämtliche Füllelemente 3 gemeinsam vorgesehen und während des Füllbetriebes teilweise, d.h. bis zu einem Niveau N niveaugesteuert mit dem flüssigen Füllgut gefüllt, so dass im Kessel 14 über dem Niveau N, welches deutlich über dem Höhenniveau des mit der Gassperre 5 versehenen Abgabebereichs liegt, ein Gasraum 14.1 und darunter ein Flüssigkeitsraum 14.2 gebildet ist und in welchen am Boden die Leitung 13 sowie eine Leitung 15 zum Zuführen des flüssigen Füllgutes münden.In the housing 7 of each filling element 3, a liquid channel 8 is provided for the liquid product, with a controllable by an actuator 9 liquid valve 10, which is essentially formed by a valve seat 11 cooperating with a valve body. The liquid valve 10 and its valve body 11 are in the FIG. 1 shown in the closed position, so that the liquid channel 8 is divided in this operating state into two separate sections 8.1 and 8.2, of which the upper section 8.1 is connected via a flow meter 12 having a line 13 with a boiler 14. The boiler 14 is provided in common for all the filling elements 3 and partially filled during filling operation, ie level-controlled with the liquid filling material to a level N, so that in the boiler 14 above the level N, which is clearly above the height level of the provided with the gas lock 5 Abgabebereich is located, a gas space 14.1 and below a liquid space 14.2 is formed and in which open at the bottom of the line 13 and a line 15 for supplying the liquid filling material.

Der Teilabschnitt 8.2 des Flüssigkeitskanals bildet an seinem unteren Ende den mit der Gassperre 5 versehenen Abgabebereich. Die Gassperre 5 ist bei der dargestellten Ausführungsform ein Einsatz mit einer Vielzahl von beidendig offenen Kanälen.The section 8.2 of the liquid channel forms at its lower end provided with the gas barrier 5 discharge area. The gas barrier 5 is in the illustrated embodiment, an insert with a plurality of open at both ends channels.

Durch die Betätigungseinrichtung 9 ist der Ventilkörper 11 zum Öffnen des Flüssigkeitsventils 10 aus der Schließstellung in Richtung der Gassperre 5 bewegbar, und zwar in wenigstens zwei unterschiedliche Öffnungsstellungen, nämlich in eine erste Öffnungsstellung, in der das Flüssigkeitsventil 10 für ein Bremsfüllen mit einem reduzierten Öffnungsquerschnitt geöffnet ist, und in eine zweite Öffnungsstellung, in der das Flüssigkeitsventil 10 für ein Schnellfüllen mit einem größerem Öffnungsquerschnitt geöffnet ist.By the actuator 9, the valve body 11 for opening the liquid valve 10 from the closed position in the direction of the gas lock 5 is movable, in at least two different open positions, namely in a first open position in which the liquid valve 10 is opened for a brake filling with a reduced opening cross-section is, and in a second open position in which the liquid valve 10 is opened for a fast filling with a larger opening cross-section.

Im Gehäuse 7 des Füllelementes 3 ist weiterhin ein Strömungsweg 16 ausgebildet, der den Teilabschnitt 8.1 mit einem Ringkanal 17 verbindet, der für sämtliche Füllelemente 3 oder aber für eine Gruppe von Füllelementen 3 der Füllmaschine gemeinsam vorgesehen ist. Im Strömungskanal 16 ist ein Ventil 18 vorgesehen, welches im Wesentlichen aus einem durch eine Druckfeder in Ventilschließstellung vorgespannten Ventilstößel 18.1 und aus einer den Ventilkörper bildenden Membrane 18.2 besteht und so ausgeführt ist, dass es bei einem Druck P1 nach Art eines Druckbegrenzungsventils öffnet, und zwar insbesondere auch für eine Strömung im Strömungskanal 16 vom Teilabschnitt 8.1 in den Ringkanal 17.In the housing 7 of the filling element 3, a flow path 16 is further formed, which connects the section 8.1 with an annular channel 17 which is provided for all filling elements 3 or for a group of filling elements 3 of the filling machine together. In the flow channel 16, a valve 18 is provided, which consists essentially of a biased by a compression spring in the valve closing position valve stem 18.1 and a valve body forming the membrane 18.2 and is designed so that it opens at a pressure P1 in the manner of a pressure relief valve, namely in particular for a flow in the flow channel 16 from the section 8.1 in the annular channel 17th

Im Gehäuse 7 des Füllelementes 3 ist weiterhin ein Strömungskanal 19 gebildet, der den Abschnitt des Strömungskanals 16 zwischen dem Ventil 18 und dem Ringkanal 17 mit einem Raum 20 verbindet, der innerhalb eines glockenartigen, an der Unterseite des Gehäuses 7 vorgesehenen Elementes 21 gebildet und während des Füllbetriebes an der Unterseite des Füllelementes 3 offen ist (Öffnung 21.1). Im Raum 20 ist der von der Gassperre 5 gebildete Abgabebereich aufgenommen.In the housing 7 of the filling element 3, a flow channel 19 is further formed which connects the portion of the flow channel 16 between the valve 18 and the annular channel 17 with a space 20 formed within a bell-shaped, provided on the underside of the housing 7 element 21 and during the filling operation at the bottom of the filling element 3 is open (opening 21.1). In the space 20 of the gas barrier 5 formed by the dispensing area is added.

Im Strömungskanal 19 ist ein Ventil 22 vorgesehen, welches in gleicher Weise wie das Ventil 18 ausgebildet ist und im Wesentlichen aus einem durch eine Druckfeder in Ventilschließstellung vorgespannten Ventilstößel 22.1 und aus einer den Ventilkörper bildenden Membrane 22.2 besteht und so ausgeführt ist, dass es bei einem Druck P2 nach Art eines Druckbegrenzungsventils öffnet. Der Ringkanal 17 ist mit einer Leitung 23 verbunden, die Teil eines Heißumlaufs für das flüssige Füllgut ist und in der ein elektrisch betätigbares Steuerventil 24 angeordnet ist.In the flow channel 19, a valve 22 is provided, which is formed in the same way as the valve 18 and consists essentially of a biased by a compression spring in the valve closing position valve tappet 22.1 and a valve body forming the membrane 22.2 and is designed so that it at a Pressure P2 opens in the manner of a pressure relief valve. The annular channel 17 is connected to a line 23 which is part of a hot circulation for the liquid product and in which an electrically actuated control valve 24 is arranged.

Mit dem Füllsystem 1 sind unterschiedlichste Betriebsweisen möglich.With the filling system 1 a variety of operations are possible.

Füllbetrieb mit Beheizen und/oder Warmhalten der Füllelemente 3Filling operation with heating and / or keeping the filling elements 3 warm

Die Figur 1 zeigt das Füllelement 3 im geschlossenen Zustand, d.h. in einer Füllpause, beispielsweise nach der Beendigung einer Füllphase bzw. nach Beendigung des Füllens einer Flasche 2 und vor dem Beginn einer neuen Füllphase nach dem Einschieben einer leeren Flasche 2 in den Behälterträger 4.The FIG. 1 shows the filling element 3 in the closed state, ie in a filling pause, for example after the completion of a filling phase or after completion of filling a bottle 2 and before the start of a new filling phase after insertion of an empty bottle 2 in the container carrier. 4

Das für sämtliche Füllelemente 3 oder eine Gruppe von Füllelementen 3 gemeinsame Steuerventil 24 ist beim Heißabfüllen generell geöffnet, so dass das heiße flüssige Füllgut alle Füllelemente 3 der Füllmaschine, die sich gerade im geschlossenen Zustand befinden, in einem Heißumlauf durchströmen kann, der den Kessel 14, die Leitung 13, den Teilabschnitt 8.1, den Strömungskanal 16, den Ringkanal 17, die Leitung 23 sowie eine nicht dargestellte Füllgut-Erhitzungsanlage einschließt, von der das Füllgut über die Leitung 15 in den Kessel 14 zurückgeführt wird. Um diesen das Beheizen und/oder Warmhalten der Füllelemente 3 bewirkenden Heißluftumlauf zu ermöglichen, ist das Ventil 18 jeder Füllelementes 3 so eingestellt, dass es bei geschlossenem Flüssigkeitskanal 8 bzw. Flüssigkeitsventil 10 durch den anstehenden Füllgutdruck P1 öffnet, bei geöffnetem Flüssigkeitskanal 8 bzw. Flüssigkeitsventil 10 aber schließt.The common for all filling elements 3 or a group of filling elements 3 control valve 24 is generally open during hot filling, so that the hot liquid product can flow through all filling elements 3 of the filling machine, which are currently in the closed state, in a hot circulation, the boiler 14th , the line 13, the section 8.1, the flow channel 16, the annular channel 17, the conduit 23 and a Füllgut-heating system, not shown, includes, from which the contents via the line 15 is returned to the boiler 14. To this to allow the heating and / or keeping warm the filling elements 3 causing hot air circulation, the valve 18 of each filling element 3 is set so that it opens when the liquid channel 8 or liquid valve 10 through the upcoming Füllgutdruck P1, with the liquid channel 8 and liquid valve 10 but closes.

Durch Öffnen des Flüssigkeitsventils 10 wird die Füllphase eingeleitet, wofür beispielsweise für ein Schnellfüllen der Ventilkörper 10 durch die Betätigungseinrichtung 9 in seine zweite Öffnungsstellung bewegt wird. Das heiße flüssige Füllgut fließt dann als freier Strahl von dem von der Gassperre 5 gebildeten Abgabebereich in die mit ihrer Flaschenmündung 2.2 auch von der Öffnung 20.1 beabstandete Flasche 2. Die der Flasche 2 zufließende Füllgutmenge wird mit dem Durchflussmesser 12 gemessen, der ein in dieser Menge entsprechendes Messsignal an eine zentrale Steuereinrichtung der Füllmaschine liefert. Bevor die Füllphase beendet wird, erfolgt unter Berücksichtigung des vom Durchflussmesser 12 gelieferten Messsignals ein Bremsfüllen. Hierfür wird der Ventilkörper 11 durch die Betätigungseinrichtung 9 in seine erste Öffnungsstellung mit reduziertem Öffnungsquerschnitt bewegt, so dass das flüssige Füllgut dann verlangsamt aber weiterhin im freien Strahl der Flasche 2 zufließt.By opening the liquid valve 10, the filling phase is initiated, for which, for example, a fast filling of the valve body 10 is moved by the actuator 9 in its second open position. The hot liquid product then flows as a free jet of the dispensing area formed by the gas barrier 5 in the bottle 2 with its bottle mouth 2.2 also spaced from the opening 20.1 bottle 2 of the bottle 2 inflowing product quantity is measured with the flow meter 12, the one in this amount corresponding measurement signal to a central control device of the filling machine supplies. Before the filling phase is ended, taking into account the measurement signal supplied by the flow meter 12, a brake filling takes place. For this purpose, the valve body 11 is moved by the actuator 9 in its first open position with reduced opening cross-section, so that the liquid contents then slows down but continues to flow in the free stream of the bottle 2.

Während des Schnellfüllens und des Langsamfüllens ist der am Ventil 18 anstehende Druck des flüssigen Füllgutes so reduziert, dass das Ventil 18 geschlossen ist. Hierzu trägt u.a. auch bei, dass der Strömungskanal 16 einen im Vergleich zum geöffneten Flüssigkeitskanal 8 reduzierten Strömungsquerschnittes aufweist und schräg in einen zwischen dem Ventilkörper 11 und der Wandung des Flüssigkeitskanals 8 gebildeten Ringspalt mit reduziertem Strömungsquerschnitt mündet, so dass durch das den Flüssigkeitskanal 8 durchströmende und der Flasche 2 zufließende Füllgut in eine Art Venturi-Effekt der auf das Ventil 18 einwirkende Füllgutdruck reduziert wird.During rapid filling and slow filling, the pressure of the liquid filling material present at the valve 18 is reduced so that the valve 18 is closed. Contributes to this, inter alia, that the flow channel 16 has a reduced compared to the opened liquid channel 8 flow cross-section and obliquely into one formed between the valve body 11 and the wall of the liquid channel 8 annular gap with reduced flow cross-section opens, so that is reduced by the liquid flowing through the channel 8 and the bottle 2 inflowing product in a kind Venturi effect acting on the valve 18 Füllgutdruck.

Dadurch, dass das Ventil 18 beim Öffnen des Flüssigkeitsventils 10 selbsttätig schließt, ist während des Füllprozesses der über den Strömungskanal 16 verlaufende Heißumlauf unterbrochen, so dass eine einwandfreie Messung des der jeweiligen Flasche 2 zugeführten Füllgutes mit dem Durchflussmesser 12 und damit eine volumengenaue Füllung der Flaschen 2 mit dem flüssigen Füllgut möglich sind. Durch die beschriebene Ausbildung des Strömungskanals 16 und des dortigen Ventils 18 ist es weiterhin auch nicht erforderlich, im Strömungskanal 16 ein durch die Steuerelektronik der Füllmaschine angesteuertes Steuerventil vorzusehen.Characterized in that the valve 18 automatically closes when opening the liquid valve 10 is interrupted during the filling process of the running over the flow channel 16 hot circulation, so that a perfect measurement of the respective bottle 2 supplied contents with the flow meter 12 and thus a volume accurate filling of the bottles 2 are possible with the liquid contents. Due to the described design of the flow channel 16 and the local valve 18, it is also not necessary to provide in the flow channel 16 a controlled by the control electronics of the filling machine control valve.

Das Ventil 22 ist so ausgebildet, dass es bei dem während des Füllprozesses anliegenden Druck P1 sperrt. Der Füllprozess wird durch Schließen des Flüssigkeitsventils 10 beendet, wodurch dann wieder der am Ventil 18 anstehende Druck P1 ausreicht, um dieses Ventil zu öffnen und damit den Heißumlauf des heißen flüssigen Füllgutes zu ermöglichen.The valve 22 is designed to block at the pressure P1 applied during the filling process. The filling process is terminated by closing the liquid valve 10, which then again the pending on the valve 18 pressure P1 is sufficient to open this valve and thus to allow the hot circulation of the hot liquid filling material.

CIP-Reinigung und/oder -SterilisationCIP cleaning and / or sterilization

Die Figur 3 zeigt das Füllsystem 1 in einem Betriebszustand für eine CIP-Reinigung und/oder -Sterilisation. Hierfür wird durch Schwenken des Behälterträgers 4 eine an diesem Behälterträger vorgesehene Verschlusskappe 25 an der Unterseite des Füllelementes 3 angeordnet und dort gegen eine die Öffnung 21.1 umschließende Ringdichtung 26 angedrückt, und zwar zum Verschließen des Raumes 20 und zur Bildung eines dichten Spülraumes an der Unterseite jedes Füllelementes 3.The FIG. 3 shows the filling system 1 in an operating state for a CIP cleaning and / or sterilization. For this purpose, by pivoting the container carrier 4 provided on this container carrier cap 25 at the bottom of Filling element 3 is arranged and pressed there against a the opening 21.1 enclosing annular seal 26, for closing the space 20 and to form a dense flushing chamber at the bottom of each filling element. 3

Bei vollständig geöffnetem Flüssigkeitsventil 10, d.h. bei in der zweiten Öffnungsstellung befindlichem Ventilkörper 11 wird dann das für die CIP-Reinigung und/oder -Sterilisation verwendete flüssige Reinigungs- oder Sterilisationsmedium dem Kessel 14 über die Leitung 15 mit einem Druck P2 zugeführt, und zwar derart, dass das Reinigungs- und/oder Sterilisationsmedium den Innenraum des Kessels 14 vollständig ausfüllt. Durch den Druck P2 des Reinigungs- oder Sterilisationsmediums, der wesentlich höher ist als der Druck P1, werden beide Ventil 18 und 22 geöffnet, so dass das Reinigungs- oder Sterilisationsmediums sämtliche Füllelemente 3 durchströmen kann, d.h. über die jeweilige Leitung 13 dem Flüssigkeitskanal 8 zufließt und diesen Flüssigkeitskanal 8 durchströmend teilweise über den Strömungskanal 16 und teilweise über den Abgabebereich bzw. die Gassperre 5, über den nach Außen geschlossenen Spülraum 20 und über den Strömungskanal 19 in den Ringkanal 17 gelangt, aus dem das Reinigungs- oder Sterilisationsmedium über die Leitung 23 mit dem geöffneten Ventil 24 abgeführt wird.When the liquid valve 10 is fully open, i. when in the second open position valve body 11 then the liquid cleaning or sterilization medium used for the CIP cleaning and / or sterilization is supplied to the boiler 14 via line 15 with a pressure P2, in such a way that the cleaning and / or sterilization medium completely fills the interior of the boiler 14. By the pressure P2 of the cleaning or sterilizing medium, which is substantially higher than the pressure P1, both valves 18 and 22 are opened, so that the cleaning or sterilizing medium can flow through all the filling elements 3, i. flows through the respective line 13 to the liquid channel 8 and this liquid channel 8 flows through partly through the flow channel 16 and partially via the delivery area or the gas lock 5, via the closed to the outside wash chamber 20 and via the flow channel 19 into the annular channel 17, from the the cleaning or sterilization medium is discharged via the line 23 with the valve 24 open.

Durch die beschriebene Ausbildung des Strömungskanals 19 und des dortigen Ventils 22 ist es ebenfalls nicht erforderlich, im Strömungskanal 19 ein durch die Steuerelektronik der Füllmaschine angesteuertes Steuerventil vorzusehen. Jedes Füllelement kommt somit mit einem einzigen durch die Steuerelektronik der Füllmaschine angesteuerten Betätigungselement 9 mit beispielsweise nur zwei Stellelementen oder -zylindern aus.The described design of the flow channel 19 and the local valve 22, it is also not necessary to provide in the flow channel 19 a controlled by the control electronics of the filling machine control valve. Each filling element thus comes with a single by the control electronics of Filling machine driven actuator 9 with, for example, only two actuators or cylinders.

Beim Ventil 18 wirkt im Wesentlichen der Druck im Teilabschnitt 8.1 des Flüssigkeitskanals 8 und bei dem Ventil 22 der Druck im Raum 20 steuernd, und zwar zumindest beim Öffnen des jeweiligen Ventils, da diese Drücke bei jeweils geschlossenem Ventil auf die größere Fläche der den Ventilkörper bildenden Membrane 18.2 bzw. 22.2 einwirken.In the case of the valve 18, the pressure in the partial section 8.1 of the fluid channel 8 and in the valve 22 the pressure in the chamber 20 acts, at least when the respective valve is opened, since these pressures in each case closed valve on the larger surface of the valve body forming Diaphragm 18.2 or 22.2 act.

Die beschriebenen Ventile 18 und 22, insbesondere auch mit dem jeweiligen membranartigen Ventilkörper haben den Vorteil, dass die Funktion dieser Ventile durch Faser- und/oder Feststoffe, die vielfach im flüssige Füllgut, beispielsweise in Fruchtsäften enthalten sind, nicht beeinträchtigt wird.The described valves 18 and 22, in particular with the respective membrane-like valve body have the advantage that the function of these valves by fiber and / or solids, which are often contained in the liquid product, for example in fruit juices, is not affected.

Die Erfindung wurde voranstehend an einem Ausführungsbeispiel beschrieben. Es versteht sich, dass Änderungen sowie Abwandlungen möglich sind.The invention has been described above by means of an embodiment. It is understood that changes and modifications are possible.

Vorstehend wurde davon ausgegangen, dass die Ventile 18 und 22 zumindest hinsichtlich ihrer Wirkung Druckbegrenzungsventilen entsprechen, d.h. das Ventil 18 bei dem bei geschlossenem Flüssigkeitsventil 10 anstehenden Füllgutdruck P1 öffnet, der im Wesentlichen gleich dem hydrostatischen Druck aufgrund des Höhenunterschiedes zwischen dem Niveau N des Füllgutspiegels im Kessel 14 und der Höhenlage des Ventils 18 ist, während das Ventil 22 erst bei dem sehr viel höheren Druck P2 des Reinigungs- und/oder Sterilisationsmediums während der CIP-Reinigung- und/oder Sterilisation öffnet.Above, it was assumed that the valves 18 and 22 at least in terms of their effect pressure relief valves, ie the valve 18 opens at the present at the closed liquid valve 10 Füllgutdruck P1, which is substantially equal to the hydrostatic pressure due to the height difference between the level N of Füllgutspiegels in Boiler 14 and the altitude of the valve 18 is, while the valve 22 only at the very much higher pressure P2 of the cleaning and / or sterilization medium during CIP cleaning and / or sterilization opens.

Grundsätzlich besteht auch die Möglichkeit für die Ventile 18 und 22 andere Ventiltypen einzusetzen, beispielsweise Rückschlagventile oder aber solche Ventile, die auf eine Druckdifferenz zwischen dem Ventileingang und dem Ventilausgang ansprechen und dann öffnen bzw. schließen, wenn diese Druckdifferenz einen vorgegebenen Schwellwert übersteigt bzw. unterschreitet.
