Unter "Freistrahlfüllen" oder Freistrahlbefüllung" wird im Rahmen der vorliegenden Erfindung ein Füllverfahren verstanden, bei dem das flüssige Füllgut dem zu befüllenden Behälter ab dem Flüssigkeitsventil in einem freien Füllstrahl oder Füllgutstrahl zuströmt, wobei die Strömung des Füllgutes nicht durch Leitelemente wie z.B. Ableitschirme, Drallkörper, kurze oder lange Füllrohre beeinflusst oder verändert wird. Freistrahlfüllen kann sowohl drucklos, also auch unter Druck erfolgen. Bei der drucklosen Freistrahlfüllung weist der Behälter Umgebungsdruck auf, wobei der Behälter in der Regel mit seiner Behältermündung oder -Öffnung nicht am Füllelement anliegt, sondern von dem Füllelement bzw. von einer vorgesehenen Abgabeöffnung beabstandet ist. Liegt der Behälter bei der drucklosen Freistrahlfüllung doch mit seiner Behältermündung am Füllelement an, so stellt ein Gasweg eine Verbindung zwischen dem Innenraum des Behälters und der Umgebung her, wodurch eine drucklose Füllung ermöglicht wird. Bevorzugt entweicht über diesen Gasweg auch das im Behälter enthaltene und durch das in den Behälter einströmende Getränk verdrängte Gas in die Umgebung. Erfolgt die Freistrahlfüllung unter einem vom Umgebungsdruck abweichenden Druck, welcher sowohl über, als auch unter dem Umgebungsdruck liegen kann, so wird der Behälter mit seiner Mündung gegen das Füllelement angepresst und abgedichtet, worauf der Druck im Innenraum des Behälters anschließend durch Beaufschlagung mit einem Spanngas oder durch Beaufschlagung mit einem Unterdruck eingestellt wird.In the context of the present invention, "free-jet filling" or "free-jet filling" is understood as meaning a filling process in which the liquid product flows to the container to be filled from the liquid valve in a free filling jet or Füllgutstrahl, wherein the flow of the filling material not by guiding elements such as Ableitschirme, swirl body In the case of pressureless jet filling, the container has ambient pressure, whereby the container as a rule does not bear against the filling element with its container mouth or opening, but rather from If the container at the non-pressurized jet filling but with his container mouth on the filling element, so a gas path connects between the interior of the container and the environment ago, thereby creating a e unpressurized filling is possible. Preferably, the gas contained in the container and displaced by the beverage flowing into the container escapes into the environment via this gas path. If the free-jet filling under a different pressure from the ambient pressure, which may be both above and below the ambient pressure, the container is pressed with its mouth against the filling element and sealed, whereupon the pressure in the interior of the container then by applying a tension gas or is adjusted by applying a negative pressure.
Das Gegenteil der zuvor beschriebenen Freistrahlfüllung stellt ein Füllverfahren dar, bei dem das flüssige Füllgut dem zu befüllenden Behälter ab dem Flüssigkeitsventil unter Beeinflussung der Strömung des Füllgutes durch Leitelemente wie z.B. Ableitschirme und/oder Drallkörper und/oder kurze oder lange Füllrohre zuströmt. Auch dieses Füllverfahren kann sowohl drucklos, also auch unter Druck erfolgen.The opposite of the previously described free-jet filling represents a filling process in which the liquid product flows to the container to be filled from the liquid valve under influence of the flow of the contents by guiding elements such as Ableitschirme and / or swirl body and / or short or long filling tubes. This filling process can also be done without pressure, so under pressure.
In Dichtlage mit dem Füllelement befindlicher Behälter bedeutet im Sinn der vorliegenden Erfindung, dass der jeweils zu füllende Behälter mit seiner Behältermündung gas- und/oder flüssigkeitsdicht an das Füllelement bzw. an eine dortige, die wenigstens eine Abgabeöffnung umgebende, Dichtungseinrichtung angepresst anliegt.In sealing position with the filling element befindlicher container means in the sense of the present invention that the container to be filled with its container mouth gas and / or liquid-tight against the filling element or to a local there, the at least one dispensing opening surrounding sealing means pressed pressed.
Das Zuführen des Spanngases in den jeweiligen Behälter sowie das Abführen des Rückgases aus dem jeweiligen Behälter erfolgen bei bekannten Füllelementen bzw. Füllelementanordnungen über ein im Füllelement ausgebildeten gesteuerten Gasweg mit mehreren Gaskanälen, in denen ein oder mehrere Steuerventile angeordnet sind. Die Steuerventile sind dann beispielsweise Bestandteil einer pneumatischen Steuerventilanordnung und über wenigstens ein elektrisch steuerbares Schaltventil von einer Maschinensteuerung der Füllmaschine gesteuert. Insbesondere der Rückgaskanal ist bei aus dem Stand der Technik bekannten Füllelementanordnungen mitunter einer hohen Verkeimungs- und/oder Kontaminationsbelastung ausgesetzt.The feeding of the clamping gas into the respective container and the discharge of the return gas from the respective container take place in known filling elements or Füllelementanordnungen via a formed in the filling element controlled gas path with multiple gas channels in which one or more control valves are arranged. The control valves are then, for example, part of a pneumatic control valve arrangement and controlled by at least one electrically controllable switching valve of a machine control of the filling machine. In particular, the return gas channel is sometimes exposed in known from the prior art Füllelementanordnungen a high contamination and / or contamination load.
Aufgabe der vorliegenden Erfindung ist es demnach, eine Füllelementanordnung aufzuzeigen, die zur Freistrahlfüllung unter Umgebungsdruck, als auch unter einem, vom Umgebungsdruck abweichenden Druck gleichermaßen ist, ohne dass bei einer Umstellung zwischen den beiden Füllverfahren bauliche Veränderungen des Füllelementes erforderlich sind und zudem ein gegenüber dem Stand der Technik reduziertes Verkeimungs- bzw. Kontaminationsrisiko des Rückgaskanals aufweist. Zur Lösung dieser Aufgabe ist eine Füllelementanordnung entsprechend den Merkmalen des Patentanspruches 1 ausgebildet. Eine Füllmaschine ist Gegenstand des Patentanspruches 20. Die jeweiligen Unteransprüche betreffen dabei besonders vorteilhafte Ausgestaltungen der Erfindung.Object of the present invention is therefore to show a Füllelementanordnung that is equal to the free-jet filling under ambient pressure, as well as under a different pressure from the ambient pressure without structural changes in the filling element are required in a changeover between the two filling and also a respect to the The prior art has reduced risk of contamination or contamination of the return gas channel. To solve this problem, a Füllelementanordnung is formed according to the features of

Die Füllelementanordnung 1 ist zusammen mit einer Vielzahl gleichartiger, weiterer Füllelementanordnungen 1 vorzugsweise in gleichen Winkelabständen am Umfang eines um eine vertikale Maschinenachse umlaufend antreibbaren Rotors 4 einer Füllmaschine umlaufender Bauart vorgesehen.The
An dem nur teilweise dargestellten Rotor 4 befindet sich ein in den Figuren nicht dargestellter, für sämtliche Füllelementanordnungen 1 der Füllmaschine gemeinsamer, das Füllgut bereitstellender Füllgutkessel, beispielsweise in Form eines Ringkessels. Im Kessel können während des Füllbetriebs ein oberer Gasraum und ein unterer Flüssigkeitsraum ausgebildet sein. Dient die Füllelementanordnung 1 zum Druckabfüllen des flüssigen Füllgutes in die Behälter 3, so ist der Gasraum druckgesteuert mit einem unter einem Fülldruck stehenden Inertgas, beispielweise CO2-Gas, beaufschlagt. Beim dargestellten Ausführungsbeispiel sind weiterhin für sämtliche Füllelementanordnungen 1 ebenfalls gemeinsame Ringkanäle 5.1 sowie 5.2 vorgesehen, auf die später noch im Detail eingegangen wird. Auch die Anordnung von gemeinsamen Ringkanälen 5.1 und 5.2 ist nicht zwingend, alternativ können das Füllgut und/oder die Prozessgase auch direkt über mindestens einen Drehverteiler den Füllelementen 2 zugeführt oder von diesen abgeführt werden.On the
Das Füllelement 2 umfasst unter anderem ein Flüssigkeitsventil 6 mit wenigstens einem Ventilgehäuse 7, das an der einer Abgabeöffnung 17 des Füllelements 2 zugewandten Seite eine Mündungsöffnung 8 aufweist, wobei in dem Ventilgehäuse 7 ein beim Füllen von dem flüssigen Füllgut durchströmter Flüssigkeitskanal 9 ausgebildet ist, der in seinem oberen Bereich über eine Produktleitung 10 und ein Steuer- bzw. Flüssigkeitsventil 11 mit dem gemeinsamen Füllgutkessel verbunden ist. Im Detail mündet die Produktleitung 10 über eine in dem Ventilgehäuse 7 vorgesehene Eintrittsöffnung 7.1 in den Flüssigkeitskanal 9, deren Achse horizontal oder im Wesentlichen horizontal, d. h. senkrecht zur Füllelementachse FA orientiert ist, so dass das flüssige Füllgut bezogen auf die vertikale Maschinenachse in einer Strömungsrichtung radial nach außen in den Flüssigkeitskanal 9 eintritt.The filling
Im Ventilgehäuse 7 und damit im Flüssigkeitskanal 9 ist weiterhin wenigstens ein Ventilkörper 12 vorgesehen, welcher bei der dargestellten Ausführungsform mit einem Ventilsitz 13 zusammenwirkt, so dass zum Öffnen und Schließen des Flüssigkeitsventils 6 insbesondere der Ventilkörper 12 in Richtung der vertikalen Füllelementachse FA aus der in der
Flüssigkeitsventil 6 öffnende Position, gezeigt in
Das Füllelement 2 umfasst ferner ein Füllelementgehäuse 16, das einen ersten, ortsfest angeordneten Füllelementgehäuseabschnitt 16.1 sowie einen zweiten, relativ dazu entlang der Füllelementachse FA zwischen einer in
Hierfür kann der zweite Füllelementgehäuseabschnitt 16.2 die Dichtungseinrichtung 18 aufweisen, die wenigstens an einer der Mündungsöffnung 8 zugewandten ersten Anlagenseite 16.2.1 an dem zweiten Füllelementgehäuseabschnitt 16.2 angeordnet und die Mündungsöffnung 8 gas- und/oder flüssigkeitsdicht - und damit auch den Rückgaskanal 33 - in der angehobenen Position ANP radial umlaufend umschließen kann, ohne dabei in den durch die Mündungsöffnung 8 strömenden Flüssigkeitsstrahl während des Füllvorgangs zu ragen bzw. in diesen vorzustehen. Alternativ ist es auch möglich, dass die erste Anlagenseite 16.2.1 zumindest abschnittsweise aus einem dichtenden Material, beispielweise einem gummiartigen Material, ausgebildet ist und damit die wenigstens eine Dichtungseinrichtung 18 bildet. Dabei kann vorgesehen sein, dass der zweite Füllelementgehäuseabschnitt 16.2 die Abgabeöffnung 17 bildet und als Ringkörper mit einem in der geschnittenen Seitenansicht V-förmigen Querschnitt ausgebildet ist. Der zweite Füllelementgehäuseabschnitt 16.2 kann damit sowohl an der der Mündungsöffnung 8 zugewandten ersten Anlagenseite 16.2.1, als auch einer der Behältermündung 3.2 zuweisenden zweiten Anlagenseite 16.2.2 jeweils als Konus, bzw. konusartig ausgebildet sein. Damit bildet sich ein Ringkörper aus, der in der angehobenen Position ANP mit seiner ersten Anlagenseite 16.2.1 an der Mündungsöffnung 8 in Dichtlage anliegt und damit wenigstens den Rückgaskanal 33 gas- und/oder flüssigkeitsdicht verschließt, während dieser in der abgesenkten Position ABP mit seiner zweiten Anlagenseite 16.2.2 die Behältermündung 3.2 zentriert aufnimmt, insbesondere an dieser anliegt, und damit zudem den Rückgaskanal 33 strömungsfrei gibt.For this purpose, the second Füllelementgehäuseabschnitt 16.2, the sealing means 18 which at least at one of the
Dabei kann auch vorgesehen sein, dass die Dichtungseinrichtung 18 derart ausgebildet ist, dass sie in der angehobenen Position ANP sowohl mit der Mündungsöffnung 8 in Dichtlage gelangt, als auch in der abgesenkten Position ABP in Dichtlage wenigstens mit der Behältermündung 3.1. Alternativ ist es auch möglich, dass die zweite Anlagenseite 16.2.2 zumindest abschnittsweise aus einem dichtenden Material, beispielweise einem gummiartigen Material, ausgebildet ist und damit die wenigstens eine Dichtungseinrichtung 18 bildet. Beispielsweise kann die Dichtungseinrichtung 18 hierfür als einteilig ausgebildete, an dem zweiten Füllelementgehäuseabschnitt 16.2 radial umlaufend angeordnete Dichtung ausgebildet sein, die sich an der jeweiligen Anlagenseite 16.2.1 sowie 16.2.2. umlaufend erstreckt. Alternativ ist es auch möglich, dass die Dichtungseinrichtung 18 mehrteilig, insbesondere zweiteilig, ausgebildet ist, wobei ein erster Teil der Dichtungsrichtung 18 dann in der angehobenen Position an der Mündungsöffnung 8 in Dichtlage anliegt und ein zweiter Teil in der abgesenkten Position ABP in Dichtlage mit der Behältermündung 3.1.It can also be provided that the sealing
Vorzugsweise weist der zweite Füllelementgehäuseabschnitt 16.2 an seiner Außenseite eine zumindest teilweise radial umlaufende Ausnehmung 38 auf, in die ein an einer Hubstange 36 mechanisch fest angeordnetes Verbindungsstück 37 formschlüssig eingreift. Die Hubstange 36 erstreckt sich dabei im Wesentlichen längs einer Parallelen der Füllelementachse FA und ist mittels einer nicht näher dargestellten Betätigungseinrichtung 39 vertikalbeweglich, also längsbeweglich, ausgebildet. Beispielweise könnte es sich bei der Betätigungseinrichtung 39 um eine Pneumatikzylinderanordnung handeln. Durch die mittels des Verbindungstückes 37 erzeugte mechanische Zwangsführung zwischen dem zweiten Füllelementgehäuseabschnitt 16.2 und der Hubstange 36, kann über eine durch die Betätigungseinrichtung 39 auf die Hubstange 36 eingeleitete geregelt und/oder gesteuerte Hub- und/oder Senkbewegung der zweite Füllelementgehäuseabschnitt 16.2 vertikal entlang der Füllelementachse FA von einer angehobenen Position ANP in einer abgesenkte Position ABP und umgekehrt bewegt werden.Preferably, the second Füllelementgehäuseabschnitt 16.2 on its outer side an at least partially radially
Zudem ist zwischen dem ersten und zweiten Füllelementgehäuseabschnitt 16.1 und 16.2 der das Ventilgehäuse 7 unter Belassung des wenigstens einen Rückgaskanals 33 entlang der Füllelementachse FA gasdicht umschließend sowie dehnbar ausgebildete Gehäusewandabschnitt 16.3 vorgesehen. Insbesondere kann der Gehäusewandabschnitt 16.3 als Faltenbalg und/oder Rollmembran ausgebildet sein, so dass sich zwischen der Außenseite des Ventilgehäuses 7 und der Innenseite des Gehäusewandabschnittes 16.3 der Rückgaskanal 33 ausbildet, der beispielweise ein Ringkanal bzw. Ringspalt sein kann. Bei dem Gehäusewandabschnitt 16.3 handelt es sich also um ein flexibles, d. h. elastisch verformbares, Bauteil. Insbesondere kann der Gehäusewandabschnitt 16.3 sowohl mit dem ersten Füllelementgehäuseabschnitt 16.1 sowie auch dem zweiten Füllelementgehäuseabschnitt 16.2 gas- und/oder flüssigkeitsdicht verbunden, beispielweise verklebt, sein.In addition, between the first and second Füllelementgehäuseabschnitt 16.1 and 16.2 of the
Der erste Füllelementgehäuseabschnitt 16.1 kann dabei fest an dem Füllelement 2 angeordnet, beispielweise mit diesem verklebt, sein. Insbesondere kann der erste Füllelementgehäuseabschnitt 16.1 mit einem Füllelementträger 40 verbunden sein, mit dem das Füllelement 2 seinerseits wiederum mit dem Rotor 4 verbunden ist. Es kann dabei vorgesehen sein, dass Füllelementgehäuse 16 einteilig, insbesondere einstückig, ausgebildet ist und dabei beispielsweise mittels eines Spritzgussverfahrens hergestellt wird. Wie bereits dargestellt, bestehen für die Befestigung des ersten Füllelementgehäuseabschnitts 16.1 auch andere Möglichkeiten.The first Füllelementgehäuseabschnitt 16.1 can be fixed to the filling
Im Füllelement 2 sind weiterhin, wie aus dem Stand der Technik bekannt, verschiedene Gaskanäle 30 bzw. Strömungswege ausgebildet, die durch beispielsweise im nicht aktivierten Zustand geschlossene Steuerventile 31 und 32 steuerbar sind und so unter anderem einen Strömungsweg über den Rückgaskanal 33 durch Aktivieren bzw. Öffnen des Steuerventils 31 mit dem als beispielweise Entlastungskanal ausgebildeten Ringkanal 5.2 verbunden werden kann, sowie ein weiterer Strömungsweg, über den durch Aktivieren bzw. Öffnen des Steuerventils 32 der Rückgaskanal 33 mit dem als beispielsweise Spanngaskanal ausgebildeten Ringkanal 5.1 verbunden werden kann. Über die gesteuerten Strömungswege 30 mittels der Steuerventile 31 und 32 kann auch bei mit einem Verschluss oder mit einer Spülkappe bzw. CIP-Kappe 44 verschlossenem Ringraum und bei geöffneten Flüssigkeitsventil 6 sowie geöffneten Steuerventil 11 eine intensive CIP-Reinigung und/oder Sterilisation der Füllelemente 2 der Füllmaschine möglich, wie dies näher in
Für die drucklose Freistrahlfüllung sind die Steuerventile 31 und 32 geschlossen sowie der zweite Füllelementgehäuseabschnitt 16.2 vorzugsweise in einer angehobenen Position ANP vorgesehen. Der zu füllende Behälter 3 ist mit seiner Behälterachse vorzugsweise achsgleich mit der Füllelementachse FA und mit seiner Behältermündung 2.1 mit Abstand unterhalb der Abgabeöffnung 17 gehalten, und zwar mit seinem Mündungsflansch 2.2 hängend an einer jeden Füllelementanordnung 1 zugeordneten Behälterträger 34, der beispielsweise als Neckringhalter ausgebildet sein kann.
