Description
Die Erfindung bezieht sich auf ein Füllsystem gemäß Oberbegriff Patentanspruch 1. Ein gattungsgemäßes Verfahren ist aus dem
Verfahren und Füllsysteme zum Füllen von Behältern und dabei speziell auch zum Druckfüllen von Behältern (Füllen von Behältern unter Spann- oder Fülldruck) mit einem flüssigen Füllgut, beispielsweise mit einem CO2-haltigen Füllgut oder Getränk sind in unterschiedlichen Ausführungen bekannt, insbesondere auch in Form von Füllmaschinen umlaufender Bauart. Der jeweilige Behälter ist dabei zumindest während einer Phase eines Füllprozesses, insbesondere während der eigentlichen Füllphase, in der das Füllen des mit dem Spann- oder Fülldruck vorgespannten Behälters erfolgt, und/oder während einer dieser Füllphase vorausgehenden Spann- und/oder Vorspannphase mit einem seine Behälteröffnung umgebenden Mündungsrand mit einer Anpresskraft dicht bzw. in Dichtlage gegen das Füllelement im Bereich einer dortigen Abgabeöffnung für das flüssige Füllgut angepresst.Processes and filling systems for filling containers and in particular also for pressure filling of containers (filling of containers under tension or filling pressure) with a liquid filling material, for example with a CO2-containing filling or beverage are known in different versions, especially in the form of Filling machines of rotating design. The respective container is at least during a phase of a filling process, in particular during the actual filling phase, in which the filling of the prestressed with the clamping or filling pressure container, and / or during a filling phase preceding clamping and / or prestressing phase with a his Container opening surrounding the mouth edge with a contact force tight or pressed in sealing position against the filling element in the region of a local discharge opening for the liquid product.
Bekannt ist hierbei insbesondere auch (
Ein grundsätzlicher Vorteil eines solchen Füllsystems besteht u.a. in einer vereinfachten Steuerung der Hubeinrichtungen für die Behälterträger sowie insbesondere auch in einer Reduzierung der Anzahl und/oder der Belastung von füllelementseitigen Steuerelementen, beispielsweise von Kurvenrollen, die im Zusammenwirken mit wenigstens einer ortsfesten Steuerkurve den vom Füllelement abgesenkten Zustand der Behälterträger am Behältereinlauf sowie am Behälterauslauf der Füllmaschine zur Übergabe der leeren Behälter an die Füllelemente bzw. an die dortigen Behälterträger sowie zur Entnahme der gefüllten Behälter von den Behälterträgern sicherstellen.A fundamental advantage of such a filling system is u.a. in a simplified control of the lifting devices for the container carrier and in particular in a reduction in the number and / or the load of filling element-side controls, such as cam rollers, in cooperation with at least one fixed cam the lowered state of the container carrier on the container inlet and the container outlet Make sure the filling machine for transferring the empty container to the filling elements or to the local container carrier and for the removal of the filled containers from the container carriers.
Nachteilig ist bei derartigen Füllsystemen aber, dass der Druck des Spül- und/oder Spann- und/oder Vorspanngases durch Prozessparameter, insbesondere durch füllgutspezifische Parameter, wie Art, CO2-Gehalt und Temperatur des Füllgutes, aber auch durch maschinenbedingte Parameter, wie z.B. Leistung der Füllmaschine (gefüllte Behälter je Zeiteinheit) usw.) vorgegeben und nicht oder allenfalls nur bedingt veränderbar ist.The disadvantage of such filling systems, however, is that the pressure of the rinsing and / or clamping and / or biasing gas by process parameters, in particular by füllgutspezifische parameters such as type, CO2 content and temperature of the contents, but also by machine-related parameters, such as power the filling machine (filled containers per unit time), etc.) specified and not or at most only conditionally changeable.
Sollen nun auf ein und derselben Füllmaschine Behälter mit unterschiedlichem Mündungsdurchmesser, beispielsweise Flaschen mit einem Mündungsdurchmesser von 28, 30 oder 38mm gefüllt werden, so ist es notwendig, die pneumatische, die Anpresskraft erzeugende Einrichtung konstruktiv so auszuführen, dass sie unter Berücksichtigung des Füll- oder Spanndrucks noch die für die Behälter mit dem größten Mündungsdurchmesser ausreichende Einspann- oder Anpresskraft liefert. Dies bedeutet dann aber auch, dass diese Anpresskraft für solche Behälter mit kleinerem Mündungsdurchmesser weit über dem erforderlichen Maß liegt, mit der Folge einer unnötig hohe mechanische Belastung von Behältern mit kleinerem Mündungsdurchmesser durch die viel zu hohe Anpresskraft. Insbesondere bei dünnwandigen Behältern und/oder solchen aus Kunststoff kann dies zu einem Zerstören, zumindest aber zu einer Beschädigung der Behälter führen.If containers with different orifice diameters, for example bottles with a mouth diameter of 28, 30 or 38 mm, are to be filled on one and the same filling machine, then it is necessary to design the pneumatic device, which generates the pressing force, in such a way that it takes into account the filling or Clamping pressure still provides the sufficient for the container with the largest orifice diameter clamping or contact force. However, this also means that this contact pressure for such containers with a smaller orifice diameter is far above the required level, with the result of unnecessarily high mechanical load of containers with a smaller orifice diameter due to the excessive contact pressure. In particular, in the case of thin-walled containers and / or plastic containers, this can lead to destruction, or at least damage to the containers.
Aufgabe der Erfindung ist es, ein Füllsystem aufzuzeigen, welches es unter Beibehaltung der grundsätzlichen Vorteile, die sich aus der Erzeugung der Anpresskraft aus dem Druck des gas- und/oder dampfförmigen Prozessmediums ergeben, eine Einstellung oder Änderung oder Anpassung der jeweiligen Anpresskraft ermöglicht. Zur Lösung dieser Aufgabe ist ein Füllsystem entsprechend dem Patentanspruch 1 ausgebildet.The object of the invention is to show a filling system which, while retaining the fundamental advantages resulting from the generation of the contact force from the pressure of the gaseous and / or vaporous process medium, makes it possible to adjust or change or adapt the respective contact pressure. To solve this problem, a filling system according to the
Das gas- und/oder dampfförmige Hilfsmedium, mit dem die weitere Komponente der jeweiligen Anpresskraft erzeugt wird und dessen zumindest in der weiteren pneumatischen Einrichtung wirkende Druck einstellbar und/oder veränderbar ist, ist beispielsweise Luft, bevorzugt sterile Luft.The gaseous and / or vaporous auxiliary medium, with which the further component of the respective contact force is generated and the pressure acting at least in the further pneumatic device is adjustable and / or variable, is for example air, preferably sterile air.
Selbstverständlich kann es sich bei dem Hilfsmedium auch um eine Flüssigkeit, beispielsweise Wasser, vorzugsweise steriles Wasser oder in bestimmten Anwendungsfällen sogar um das Füllgut handeln. Somit ist im Rahmen der vorliegenden Erfindung unter dem Begriff Hilfsmedium ausdrücklich auch immer ein flüssiges Hilfsmedium zu verstehen. Lediglich zur Vereinfachung der Lesbarkeit, aber ohne Einschränkung des Schutzumfanges wird nachfolgend jeweils auf die ausdrückliche Nennung des möglicherweise auch flüssigen Hilfsmediums verzichtet.Of course, the auxiliary medium may also be a liquid, for example water, preferably sterile water or, in certain applications, even the filling material. Thus, in the context of the present invention, the term auxiliary medium expressly also always means a liquid auxiliary medium. Only to simplify the readability, but without limiting the scope of protection will be waived in each case to the express mention of possibly liquid auxiliary medium.
Das gas- und/oder dampfförmige Prozessmedium ist im Sinne dasjenige Medium, mit dem die Behälter während des Füllprozesses behandelt und/oder beaufschlagt werden, beispielsweise das Spül-Spann- und/oder Vorspanngas in Form von Inertgas, z.B. in Form von C02-Gas oder ein gas- oder dampfförmiges Medium zum Sterilisieren der Behälter vor dem Füllen. Das Prozessmedium im Sinne der Erfindung ist aber auch ein Reinigungs- und/oder Sterilisationsmedium, welches für eine Reinigung und/oder Sterilisation des Füllsystems, vorzugsweise für eine CIP-Reinigung und/oder Sterilisation des Füllsystems verwendet wird.The gaseous and / or vaporous process medium is in the sense of the medium with which the containers are treated and / or acted upon during the filling process, for example the flushing and / or biasing gas in the form of inert gas, e.g. in the form of
Bevorzugt ist das erfindungsgemäße Füllsystem so ausgebildet, dass die durch den Druck des Prozessmediums erzeugte erste Komponente der Anpresskraft größer ist als die durch den Druck des Hilfsmediums erzeugte Komponente.Preferably, the filling system according to the invention is designed so that the first component of the contact pressure generated by the pressure of the process medium is greater than the component generated by the pressure of the auxiliary medium.
Ist das Füllsystem Bestandteil einer Füllmaschine umlaufender Bauart mit einer Vielzahl von Füllelementen mit zugehörigen Behälterträgern, so erfolgt dieIf the filling system is part of a filling machine of continuous design with a plurality of filling elements with associated container carriers, then the
Steuerung beispielsweise in der Form, dass die weiteren pneumatischen Einrichtungen sämtlicher Füllelemente ständig mit dem die gewünschte oder erforderliche Einspannkraft liefernden Druck des Hilfsmediums beaufschlagt sind und die Behälterträger am Behältereinlauf sowie am Behälterauslauf gegen die Wirkung der weiteren pneumatischen Einrichtungen durch Steuerkurven in eine untere Hubstellung bewegt werden.Control, for example, in the form that the other pneumatic devices of all filling elements are constantly supplied with the desired or required clamping force supplied pressure of the auxiliary medium and the container carriers are moved to the container inlet and the container outlet against the action of further pneumatic devices by cams in a lower stroke position ,
Die Einstellung und/oder Regelung des Druckes sowohl des Prozessmediums als auch des Hilfsmediums erfolgt vorzugsweise über elektropneumatische Reglereinrichtungen, und zwar beispielsweise in Abhängigkeit von in einer elektronischen Steuereinrichtung (z.B. Prozessrechner) des Füllsystems bzw. der Füllmaschine hinterlegten Daten oder Programmen bzw. in Abhängigkeit von produkt- und maschinenbezogenen Parametern.The adjustment and / or regulation of the pressure of both the process medium and the auxiliary medium preferably takes place via electropneumatic control devices, for example as a function of data or programs stored in an electronic control device (eg process computer) of the filling system or the filling machine or in dependence on product and machine related parameters.

Der Zylinderraum 16.2 ist seinerseits stufenförmig ausgeführt, und zwar mit einem größeren Durchmesser im oberen Bereich und mit einem reduzierten Durchmesser im unteren Bereich, sodass innerhalb des Zylinderraumes 16.2 ein Anschlag oder Bund 17 gebildet ist, gegen den der Kolbenabschnitt 15.2 bei vollständig in Richtung zur Füllelementunterseite abgesenktem Kolben 15 anliegt.Each
Zumindest während des Druckfüllens der jeweiligen Flasche 2 ist der Zylinderraum 16.1 mit dem Druck P1 aus dem Gasraum 3.2 des Ringkessels 3 beaufschlagt, sodass der Kolben 15 durch den auch im Zylinderraum 16.1 herrschenden Druck P1 nach oben bewegt bzw. vorgespannt ist und hierdurch die jeweilige Flasche 2 mit ihrer Flaschenmündung 2.1 gegen die Ringrichtung 9 angepresst wird, und zwar über den Kolben 15, das Lagerelement 12, die beiden Führungsstangen 11 und den Behälterträger 10. In den Zylinderraum 16.1 mündet auch das obere offene Ende eines achsgleich mit der Achse FA angeordneten und zugleich als Ventilstößel für den Ventilkörper des Flüssigkeitsventils 6 dienenden Gasrohres 6.1, welches an seinem unteren offenen Ende den Innenraum der in Dichtlage mit dem Füllelement befindlichen Flasche 2 reicht, sodass auch diese zumindest während des Füllens mit dem Inertgas-Druck P1 vorgespannt ist.At least during the pressure filling of the
Der Druck P1 ist durch verschiedene Füll- und/oder Systemparameter fest vorgesehen, beispielsweise durch die Temperatur und/oder die Art und/oder den Inertgas bzw. CO2-Gasgehalt des flüssigen Füllgutes, sodass die Anpresskraft, die von der aus dem Kolbenabschnitt 15.1 und dem Zylinderraum 16.1 bestehenden Kolben-Zylinder-Anordnung erzeugt wird, nicht frei veränderbar ist, insbesondere auch nicht zur Anpassung dieser Anpresskraft an Behälter oder Flaschen mit unterschiedlichem Durchmesser im Bereich der Behälter oder Flaschenmündung 2.1.The pressure P1 is fixedly provided by various filling and / or system parameters, for example by the temperature and / or the type and / or the inert gas or CO2 gas content of the liquid filling material, so that the contact pressure, which of the from the piston portion 15.1 and The cylinder space 16.1 existing piston-cylinder arrangement is generated, is not freely changeable, especially not to adapt this contact pressure on containers or bottles with different diameters in the container or bottle mouth 2.1.
Der Kolbenabschnitt 15.2 bildet zusammen mit dem Zylinderraum 16.2 eine Kolben-Zylinder-Anordnung, die trotz des konstanten oder im Wesentlichen konstanten Druckes P1 eine Änderung oder Einstellung der Anpresskraft ermöglicht, mit der die betreffende Flasche 2 mit ihrem Mündungsrand 2.1 gegen die Dichtung 9 angepresst anliegt. Der Zylinderraum 16.2 ist hierfür mit einem flüssigen und/oder oder gas- und/oder dampfförmigen Hilfsmedium, beispielsweise mit Luft, vorzugsweise mit steriler Luft mit dem variablen Druck P2 beaufschlagbar, sodass die Anpresskraft insgesamt eine Funktion der Drücke P1 und P2 ist und durch Änderung des Druckes P2 veränderbar bzw. an die jeweiligen Erfordernisse, insbesondere auch an den jeweiligen Mündungsdurchmesser D1 des Behälters bzw. der Flasche 2 im Bereich der Flaschenmündung 2.1 anpassbar ist.The piston section 15.2 together with the cylinder chamber 16.2 a piston-cylinder arrangement, which despite the constant or substantially constant pressure P1 allows a change or adjustment of the contact force with which the
Durch die Erzeugung der Anpresskraft, mit der die jeweilige Flasche 2 zumindest während des Druckfüllens gegen die Ringdichtung 9 angepresst anliegt, aus dem Inertgas-Druck P1 ergeben sich u.a. eine vereinfachte Steuerung sowie eine verbesserte Betriebssicherheit für die Füllelemente 1. Ein Vorteil der Erzeugung der vorzugsweise größeren Komponente der Anpresskraft durch den Druck P1 des Prozessmediums (Spülgas und/oder Spann- und/oder Vorspanngas), z.B. Inert- oder C02-Gases besteht auch darin, dass der jeweilige Zylinderraum 16.1 im Bereich des Behälter- oder Flascheneinlaufs sowie auch im Bereich des Behälter- und Flaschenauslaufs entlastet ist, sodass sich eine reduzierte Belastung der mit der Steuerkurve 14 zusammenwirkenden Kurvenrollen 13 bei abgesenkten Behälterträgern 10 im Winkelbereich der Drehbewegung des Rotors zwischen dem Behälterauslauf und dem Behältereinlauf ergibt.By generating the contact force with which the

Zur Aufnahme der jeweils leeren, zu füllenden Flasche 2 an einem Flascheneinlauf der Füllmaschine sowie zur Entnahme der jeweils gefüllten Flasche an einem Flaschenauslauf der Füllmaschine ist der jewellige Behälterträger 10 mit der Flasche abgesenkt, und zwar beispielsweise in eine Position, in der der Kolben 15 mit seinem Kolbenabschnitt 15.2 gegen den Bund 17 anliegt. Der abgesenkte Zustand wird durch das Zusammenwirken der jeweiligen Kurvenrolle 13 mit der Steuerkurve 14 erreicht bzw. sichergestellt. Der abgesenkte Zustand des jeweiligen Behälterträgers 10 kann aber alternativ auch dadurch erreicht oder zumindest aber sichergestellt werden, dass der Zylinderraum 16.2 mit einem Unterdruck VAK beaufschlagt wird. Durch diese Vorgehensweise befindet sich der Kolben 15, wie in der
