Description
Die Erfindung betrifft eine Füllmaschine zum Füllen von Behältern wie Flaschen oder dergleichen mit einem flüssigen Füllgut gemäß der im Oberbegriff des Hauptanspruches angegebenen Gattung und wie in der
Bei der Abfüllung von Wein, Perlwein, Cidre, Sekt und dergleichen ist es erforderlich, eine besonders präzise Füllhöhengenauigkeit zu erreichen, zumal ein Teil dieser Getränke mit Naturkorken oder entsprechenden Imitaten verschlossen werden. Der Abstand zwischen dem eingeführten Korken bzw. dessen Stirnseite und dem eigentlichen Füllspiegel in der Flasche ist dabei in engen Grenzen zu halten. Insbesondere bei Überfüllungen spritzt das Getränk während des Verschließvorganges am Korkenaußenmantel vorbei ins Freie und führt zu einer aus mikrobiologischen Gründen unerwünschten Benetzung der Flasche und Teilbereichen der Verschließmaschine.When bottling wine, sparkling wine, cider, sparkling wine and the like, it is necessary to achieve a particularly precise Füllhöhengenauigkeit, especially since a portion of these drinks are sealed with natural cork or corresponding imitations. The distance between the inserted cork or its end face and the actual filling level in the bottle is to be kept within narrow limits. Particularly in the case of overfillings, during the closing process the beverage splashes past the cork outer casing and leads to unwanted wetting of the bottle and partial areas of the capping machine due to microbiological reasons.
Darüber hinaus bildet sich in der Flaschenmündung unter dem Korken ein bestimmter Überdruck, der zum Hinauspressen des eingebrachten Korkens führen kann. Gleichermaßen treten insbesondere bei teuren Getränken - ungeachtet der verwendeten Verschlussarten - zusätzliche Kosten infolge solcher unerwünschten Überfüllungen auf. Dagegen verbleibt bei ebenfalls nicht erwünschten Unterfüllungen überschüssige Luft in der Flaschenmündung, was zu einer produktschädigenden Sauerstoffaufnahme führt.In addition, forms in the bottle mouth under the cork a certain overpressure, which can lead to the pressing out of the introduced cork. Similarly, expensive drinks in particular, regardless of the types of closure used, incur additional costs as a result of such undesirable traps. On the other hand, with undesirable underfilling, excess air also remains in the mouth of the bottle, which leads to product-damaging oxygen uptake.
Zur Lösung dieser Problemstellungen zeigt der Stand der Technik Verfahren auf, die unter der Bezeichnung Trinox- Verfahren bekannt sind. Grundlage eines derartigen Verfahrens ist, dass die Flasche zunächst einmal mit einem klassischen Kurzrohrfüllsystem überfüllt wird. Anschließend wird dann das überschüssige Füllgut präzise bis zum Ende eines in den Füllgutspiegel eingetauchten Röhrchens zurück in den Ringkessel gedrückt. Hierzu ist in einem separaten Kanal im Füllerkarussell ein Druck eingeregelt, der ca. 0,3 bis 1,0 bar über dem im Ringkessel eingestellten Fülldruck liegt.To solve these problems, the prior art discloses methods known as Trinox methods. Basis of such a method is that the bottle is initially overfilled with a classic Kurzrohrfüllsystem. Subsequently, the excess filling material is then pressed back precisely into the ring bowl until the end of a tube immersed in the product level. For this purpose, a pressure is regulated in a separate channel in the filler carousel, which is about 0.3 to 1.0 bar above the filling pressure set in the ring boiler.
Unmittelbar nach dem Schließen des Flüssigkeitsventils nach dem eigentlichen Füllvorgang öffnet ein pneumatisch gesteuertes Ventil eine Verbindung von diesem Kanal in den Flaschenhals. Gleichzeitig wird der im Inneren des in den Füllgutspiegels eintauchenden Trinox-Rohres ausgebildete Weg in den Ringkessel ebenfalls elektro-pneumatisch freigegeben. Der Überdruck im Flaschenhals drückt das oberhalb der Mündung des Trinox-Rohres anstehende Produkt in den Ringkessel zurück. Der Vorgang ist beendet, sobald das Gas aus dem Flaschenhals oberhalb des Füllgutspiegels über einem definierten Spalt direkt in das Trinox-Röhrchen einfließen kann. Die Füllhöhe ist damit durch die Spaltbreite zwischen Spiegel und Rohrende oder anderweitiger Rückführöffnungen eindeutig und präzise definiert.Immediately after closing the liquid valve after the actual filling operation, a pneumatically controlled valve opens a connection from this channel into the bottleneck. At the same time, the path formed in the interior of the Trinox tube immersed in the filling material level in the ring bowl is also released electro-pneumatically. The overpressure in the bottleneck presses the product above the mouth of the Trinox tube is returned to the ring bowl. The process is completed as soon as the gas from the bottleneck above the product level can flow directly into the Trinox tube over a defined gap. The filling level is thus defined clearly and precisely by the gap width between the mirror and the pipe end or other return openings.
Ein solches Verfahren ist beispielsweise aus der
Da in der Praxis die Füllhöhen verschiedener Behältertypen oder Behälterchargen regelmäßig von einander abweichen, hat es sich als besonders vorteilhaft herausgestellt, die Trinox- oder Rückgasrohre höhenverstellbar auszubilden, wodurch die Füllhöhe in bestimmten Grenzen frei einstellbar ist.Since in practice the filling heights of different types of containers or batches of containers regularly deviate from each other, it has been found to be particularly advantageous to make the Trinox or return gas pipes adjustable in height, whereby the filling height is freely adjustable within certain limits.
Eine derartige Vorrichtung wurde zum Beispiel in der
Beispielsweise ausgehend von einem solchen Verfahren und einer zur Durchführung des Verfahrens geeigneten Vorrichtung liegt der Erfindung die Aufgabe zugrunde, hierzu eine verbesserte Weiterbildung aufzuzeigen, mit welcher unter Einsatz des Trinox-Verfahrens die Füllhöhe in den Flaschen automatisch und stufenlos je nach den gegebenen Bedingungen bei verbesserter Genauigkeit und vermindertem Verschleiß eingestellt werden kann.By way of example, starting from such a method and a device suitable for carrying out the method, it is an object of the invention to provide an improved development with which, using the Trinox method, the filling level in the bottles is automatically and steplessly improved, depending on the given conditions Accuracy and reduced wear can be adjusted.
Zur Lösung dieser, der Erfindung zugrunde liegenden Aufgabe ist eine Füllmaschine entsprechend dem Patentanspruch 1 ausgebildet. Demnach ist erfindungsgemäß vorgesehen, dass die Trinoxrohre alle Füllelemente an einem zentralen Lagerring als gemeinsamer Höhenverstelleinrichtung angeordnet sind.To solve this problem underlying the invention, a filling machine according to the
Ferner wird in selbständiger Ausgestaltung vorgeschlagen, dass in diesem Füllstutzen ein erster Gaskanal zum Zu- und Abführen von Prozessgasen und weiterer Medien vorgesehen und innerhalb dieses Gaskanals ein in seiner die Füllhöhe bestimmenden Höhe stufenlos höhenverstellbarer weiterer Gaskanal zum Zuführen eines Druckgases oberhalb des Vorspanndruckes vorgesehen ist.Furthermore, it is proposed in an independent embodiment that a first gas channel for supplying and discharging process gases and other media is provided in this filler neck and within this gas channel is provided in its height determining height infinitely height adjustable further gas channel for supplying a pressurized gas above the biasing pressure.
Mit dieser erfindungsgemäß vorgeschlagenen Ausbildung sind die eingangs genannten Anforderungen problemlos zu erfüllen und wesentlich verbesserte höhenmäßige Anpassungen des Füllstandes auch während der laufenden Abfüllung durchführbar. Manuelle Maßnahmen zur Füllhöhenanpassung und Korrektur sind nicht mehr erforderlich.With this inventively proposed training, the requirements mentioned above are easy to meet and much improved height adjustments of the level even during the current filling feasible. Manual measures for level adjustment and correction are no longer required.
Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche und der nachfolgenden Beschreibung.Further developments of the invention are the subject of the dependent claims and the following description.
Die Erfindung wird im Folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to an embodiment shown in the drawing.
In der Zeichnung ist mit 1 ein Ringkessel, der an einem ansonsten nicht dargestellten, um eine vertikale Maschinenachse umlaufenden Rotor der Füllmaschine vorgesehen ist, welche zum Füllen der Flaschen 2 mit einem Getränk, beispielsweise Sekt, unter Gegendruck dient.In the drawing, 1 with a ring vessel, which is provided on an otherwise not shown, rotating around a vertical axis of the machine rotor of the filling machine, which serves for filling the
Am Umfang des Rotors bzw. Ringkessels 1 ist eine Vielzahl von Füllstellen gebildet, von denen jede ein Füllelement 3 und unter diesem einen in vertikaler Richtung auf- und abbewegbaren Flaschenträger aufweist. Die Füllelemente 3 sind am Umfang des Ringkessels 1 befestigt. Dieser bildet einen die vertikale Maschinenachse ringförmig umschließenden Innenraum 4, der bis zu einem vorgegebenen Niveau mit dem Getränk bzw. dem flüssigen Füllgut befüllt ist, so dass unterhalb des Niveaus ein von dem flüssigen Füllgut eingenommener Flüssigkeitsraum 4 und oberhalb des Niveaus ein Gasraum für ein unter Druck stehendes Gas, beispielsweise Inertgas (z.B. CO2 -Gas) gebildet ist.On the circumference of the rotor or
Jedes Füllelement besitzt ein Gehäuse 5, in dessen unterem Teil ein Flüssigkeitskanal 6 ausgebildet ist, der mit seinem einen Ende mit dem Füllgutraum 4 in Verbindung steht und an der Unterseite des Füllelementes 3 bzw. dem Gehäuse 5 eine die vertikale Füllelementachse FA konzentrisch umschließende ringförmige Abgabeöffnung 7 bildet. Im Flüssigkeitskanal 6 ist das Flüssigkeitsventil 8 vorgesehen, welches in der Zeichnung in seiner geschlossenen Stellung dargestellt ist. Dieses Flüssigkeitsventil besteht aus einem Ventilkörper 9, der durch nicht näher dargestellte Betätigungsmittel zum Öffnen und Schließen um einen vorgegebenen Bewegungshub in Richtung der Achse FA bewegbar ist und im geschlossenen Zustand des Flüssigkeitsventils 8 mit einer Ventilkörperfläche gegen einen im Flüssigkeitskanal 6 gebildeten Ventilansatz anliegt. Mit 10 sind eine Zentriertulpe und mit 11 ein die Abgabeöffnung 7 umschließende ringförmige Dichtung bezeichnet, gegen die die in Dichtlage mit dem Füllelement 3 befindliche Flasche 2 mit ihrer Mündung angepresst anliegt.Each filling element has a
Unterhalb des Innenraumes 4 ist im Ringkessel 1 ein ringförmiger, für sämtliche Füllelemente 3 gemeinsamer Vakuumkanal 12 vorgesehen. Weiterhin ist am Ringkessel 1 oder an dem diesen Ringkessel aufweisenden Rotor ein für alle Füllelemente 3 gemeinsamer Trinox-Kanal 13 mit dem beschriebenen Überdruckgas vorgesehen.Below the
Das in der Zeichnung dargestellte Ausführungsbeispiel zeigt eine Füllventilausbildung mit einem im Inneren des Ventilkörpers sich nach oben und unten erstreckenden ersten Gaskanal 14, vorgesehen zum Zu- und Abführen des Prozessgases.The embodiment shown in the drawing shows a Füllventilausbildung with a inside the valve body extending upwardly and downwardly
Mittels der in der Figur 3 dargestellten, innerhalb des Füllventils angeordneten Ventile ist es möglich, den ersten Gaskanal 14 abwechselnd oder aber auch gleichzeitig mit dem Trinox-Kanal 13 und dem Vakuumkanal 12 zu verbinden. Durch diese Möglichkeiten kann es sich bei den, durch den ersten Gaskanal Zu- oder Abzuführenden Prozessgasen beispielsweise um im Behälter befindliches, aus dem Trinox-Kanal 13 stammendes Vorspanngas oder aber auch um aus dem Behälter abzuführende Spülluft handeln.By means of the valves shown in FIG. 3, which are arranged within the filling valve, it is possible to connect the
Innerhalb dieses ersten Gaskanals 14 erstreckt sich ein weiterer zweiter Gaskanal 15. Dieser ist in dem Ausführungsbeispiel als des eigentliche Trinox-Rohr vorgesehen und in Form eines Gasrohres 16 aus dem Füllventilgehäuse 5 nach oben zu einer zentralen Füllhöhen- Verstelleinrichtung 17 hinausgeführt, die ihrerseits an einem zentralen Lagerring 18 gehalten ist.Within this
Der Lagerring 18 ist mittels mindestens einer Antriebsvorrichtung 19 relativ zur stirnseitigen unteren Ebene der Füllelemente 3 mit den Trinox- Gasrohren 16 zur Bestimmung der jeweiligen Füllhöhe durch das eingangs beschriebene Trinox-Verfahren höhenmäßig beliebig verfahr- und einstellbar. Auf dem und/oder am Lagerring 18 sind zweckmäßig auch die für jede Füllstelle vorgesehenen Steuerventile oder - Vorrichtungen 20 angeordnet, mit denen die einzelnen Trinox-Verbindungen in den Ringkessel entsprechend den erforderlichen Prozessvorgaben gesteuert werden können.The bearing ring 18 by means of at least one
Der eigentliche Trinox-Prozess stellt sich wie folgt dar: im Anschluss an einen eventuellen Evakuierungs- und/oder Spülvorgang öffnet das Flüssigkeitsventil 8, das Füllgut strömt in den zu füllenden Behälter. Das dabei aus dem Behälter verdrängte Prozessgas strömt je nach Ansteuerung der Ventile durch den Gaskanal 14 in den Vakuumkanal 12, oder aber durch das Trinox-Gasrohr 16 in den oberhalb des Füllgutes befindlichen Gasraum 4".The actual Trinox process is as follows: following a possible evacuation and / or rinsing process, the liquid valve 8 opens, the filling material flows into the container to be filled. The thereby displaced from the container process gas flows depending on the control of the valves through the
Der Füllprozess wird durch Schließen des Flüssigkeitsventils 8 zu einem Zeitpunkt beendet, an dem der im Behälter erreichte Füllgutspiegel die Unterkante des zweiten Gaskanals 15 übersteigt. Im Anschluss daran wird durch geeignete Steuerung der Ventile aus dem Trinox-Kanal 13 stammendes Gas, welches einen höheren Druck aufweist, als das im Füllgutraum 4 befindliche Gas, durch den Gaskanal 14 in das Innere des Behälters geleitet.The filling process is terminated by closing the liquid valve 8 at a time at which the level of contents reached in the container exceeds the lower edge of the second gas channel 15. Thereafter, by appropriate control of the valves from the Trinox
Innerhalb des Behälters drückt das aus dem Trinox-Kanal 13 stammende Gas die Flüssigkeitsmenge, welche die Unterkante des zweiten Gaskanals 15 übersteigt durch diesen zweiten Gaskanal 15 zurück in den Füllgutraum 4, wodurch die gewünschte Füllhöhe exakt erreicht wird.Within the container, the gas originating from the Trinox
Das vorbeschriebene Ausführungsbeispiel kann dahingehend abgewandelt werden, dass die Zu- und Abführung des Prozessgases auch durch den Trinox-Kanal erfolgt, wobei eine entsprechende Ausbildung der Steuereinrichtung vorzusehen ist, mit welcher die Prozessgase dem Trinox-Kanal zugeleitet werden können. In entsprechender Ausbildung kann auch der Vorspannkanal zur Zuführung des einzuleitenden Trinox-Gases ausgebildet sein. In beiden Varianten sind die entsprechenden Kanäle höhenverstellbar innerhalb des Füllstutzens ausgebildet.The above-described embodiment can be modified to the effect that the supply and removal of the process gas also takes place through the Trinox channel, with a corresponding design of the control device is provided, with which the process gases can be fed to the Trinox channel. In appropriate training may also be the biasing channel for feeding the Trinox gas to be introduced. In both variants, the corresponding channels are adjustable in height formed within the filler neck.
In einer weiteren, überaus vorteilhaften Ausgestaltung der vorliegenden Erfindung ist vorgesehen, dass das nach Beendigung der Füllung im weiteren Gaskanal 14 befindliche Gas erhöhten, oberhalb des Vorspanndruckes liegenden Druckes, zum Vorspannen der nachfolgenden Behälter in diese einleitbar ist, wodurch sich beträchtliche Einsparungsmöglichkeiten hinsichtlich der Reduzierung des Verbrauches an Vorspanngas und/oder erhöhte Konzentrationen von Inertgas ergeben.In a further, highly advantageous embodiment of the present invention, it is provided that the gas present in the
