Description

Die Erfindung betrifft ein Getränkefüllorgan der im Oberbegriff des Anspruches 1 genannten Art.The invention relates to a beverage filler mentioned in the preamble of claim 1.

Ein solches Getränkefüllorgan wird von der Anmelderin seit Jahren in großer Stückzahl ausgeliefert.Such a filling device has been supplied in large numbers by the applicant for years.

Dieses bekannte Füllorgan unterscheidet sich von anderen üblichen Getränkefüllorganen vor allem durch die Führungswand, die den Ventilkörper, der den Getränkedurchlaß beherrscht, im Bereich des Ventilsitzes führend aufnimmt, so wie eine Zylinderwand einen Kolben führt. Dies hat konstruktive Vorteile hinsichtlich der exakten Ventilführung und trägt zur Vereinfachung der Konstruktion des Füllorganes bei. Die Führungswand würde den Ventilkörper auch in Öffnungsstellung allseitig abdichten. Sie ist daher bei der bekannten Konstruktion mit Öffnungen versehen, die Flüssigkeit durchlassen. Bei der bekannten Konstruktion sind diese Öffnungen möglichst groß gestaltet, um der Flüssigkeit möglichst wenig Strömungswiderstand zu bieten.This known filling element differs from other conventional beverage filling elements primarily by the guide wall, which receives the valve body, which controls the beverage passage, in the region of the valve seat, in the same way as a cylinder wall guides a piston. This has constructive advantages with regard to the exact valve guide and contributes to simplifying the construction of the filling element. The guide wall would seal the valve body on all sides even in the open position. It is therefore provided with openings in the known construction that allow liquid to pass through. In the known construction, these openings are made as large as possible in order to offer the liquid as little flow resistance as possible.

Wie alle Füllorgane üblicher Bauart zum Füllen von Getränken in gasgefüllte Behälter muß eine Gassperre im Bereich des Getränkeventils vorgesehen sein, die zwischen dem Zeitpunkt des Füllstops und dem Zeitpunkt des Schließens des Ventilkörpers das Aufsteigen von Gas aus dem Kopfraum des Behälters verhindert. Bei der bekannten Konstruktion ist eine solche Gassperre als zusätzliches Bauelement außerhalb der Führungswand in Form eines entsprechend eng bemaßten Ringspaltes vorgesehen.Like all filling organs of conventional design for filling drinks into gas-filled containers, a gas barrier must be provided in the area of the beverage valve, which prevents gas from rising from the head space of the container between the time of the filling stop and the time of closing the valve body. In the known construction, such a gas barrier is provided as an additional component outside the guide wall in the form of a correspondingly narrow annular gap.

Nachteilig bei der bekannten Konstruktion ist zunächst der hohe Strömungswiderstand, der sich aus dem Strömungswiderstand der Öffnungen der Führungswand und dem Strömungswiderstand der Gassperre addiert. Auch die Kosten der bekannten Konstruktion sind sowohl von der Führungswand als auch zusätzlich von der vorzusehenden Gassperreinrichtung beeinflußt.A disadvantage of the known construction is first of all the high flow resistance, which is added from the flow resistance of the openings in the guide wall and the flow resistance of the gas barrier. The costs of the known construction are influenced both by the guide wall and also by the gas barrier device to be provided.

Aufgabe der vorliegenden Erfindung ist es daher, ein Getränkefüllorgan der eingangs genannten Art zu schaffen, bei dem die Führungswand und die Gassperreinrichtung hinsichtlich Kosten und Flüssigkeitsdurchströmbarkeit optimiert sind.It is therefore an object of the present invention to provide a beverage filling element of the type mentioned at the outset, in which the guide wall and the gas barrier device are optimized with regard to costs and the ability to flow through liquids.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Kennzeichnungsteils des Anspruches 1 gelöst.This object is achieved with the features of the characterizing part of claim 1.

Bei der erfindungsgemäßen Konstruktion wirkt die Führungswand selbst mit ihren Öffnungen als Gassperre. Eine gesonderte Gassperreinrichtung wird daher mit ihren anfallenden Kosten und dem sich ergebenden Strömungswiderstand eingespart. Bei der Führungswand ist lediglich dafür Sorge zu tragen, daß die Öffnungen mit ihren Querschnitten gassperrend ausgebildet sind. Durch Vorsehen einer großen Anzahl derartig kleiner Öffnungen kann der Flüssigkeitsströmungswiderstand ausreichend niedrig gehalten werden. Insgesamt läßt sich gegenüber der bekannten Konstruktion der Durchströmungswiderstand für Flüssigkeiten herabsetzen, und es lassen sich die Kosten der Konstruktion verringern.In the construction according to the invention, the guide wall itself, with its openings, acts as a gas barrier. A separate gas barrier device is therefore saved with its costs and the resulting flow resistance. With the guide wall, it is only necessary to ensure that the openings with their cross sections are designed to block the gas. The liquid flow resistance can be kept sufficiently low by providing a large number of such small openings. All in all the flow resistance for liquids can be reduced compared to the known construction, and the construction costs can be reduced.

Vorteilhaft sind die Merkmale des Anspruches 2 vorgesehen. Auf diese Weise ist es beispielsweise möglich, Führungswände mit für unterschiedliche Flüssigkeiten und Gase optimierten Öffnungen auszutauschen, ohne das gesamte Füllorgan wechseln zu müssen. Ferner kann bei bekannten Füllorganen mit bereits vorhandenen abnehmbaren Führungswänden die Erfindung nachgerüstet werden.The features of claim 2 are advantageously provided. In this way it is possible, for example, to replace guide walls with openings optimized for different liquids and gases without having to change the entire filling element. Furthermore, the invention can be retrofitted to known filling elements with already existing removable guide walls.

Vorteilhafterweise werden gemäß Anspruch 3 die Öffnungen in Form von beliebig angeordneten Löchern oder aber in Form von gerade bzw. schräg verlaufenden Schlitzen vorgesehen. Derartige Öffnungen lassen sich besonders leicht in der Führungswand ausbilden.Advantageously, the openings are provided in the form of arbitrarily arranged holes or in the form of straight or inclined slots. Such openings can be formed particularly easily in the guide wall.

Eine Alternative beschreibt Anspruch 4. Danach wird vorgeschlagen, die Führungswand in Form eines oben geschlossenen Kammes oder aber in Form eines Siebes auszubilden. Derartige Konstruktionen erlauben in besonders vorteilhafter Weise eine optimale Flüssigkeitsdurchströmbarkeit bei gleichzeitig niedrigem Strömungswiderstand.An alternative is described in claim 4. It is then proposed to design the guide wall in the form of a comb closed at the top or in the form of a sieve. Such constructions allow, in a particularly advantageous manner, optimum liquid flowability with a low flow resistance at the same time.

Weiterhin vorteilhaft sind die Merkmale des Anspruches 5 vorgesehen. Auf diese Weise wird der Strömungswiderstand der Führungswand weiter herabgesetzt.The features of claim 5 are also advantageously provided. In this way, the flow resistance of the guide wall is further reduced.

Weiterhin vorteilhaft sind die Merkmale des Anspruches 6 vorgesehen. Auf diese Weise wird die Führung des Ventilkörpers nur in einem ringförmigen Bereich am oberen Ende der Führungswand bewirkt. Diese Stelle ist für die Führung am wichtigsten, da sie ständig in Eingriff mit dem Ventilkörper ist, und es wird ferner die Reibkraft verringert. Außerdem läßt sich der darunterliegende Teil der Führungs wand ohne Berücksichtigung der Führungseigenschaften frei in Hinblick auf die Gassperrwirkung konstruieren.The features of claim 6 are also advantageously provided. In this way, the valve body is only guided in an annular region at the upper end of the guide wall. This location is most important for the guide as it is constantly engaged with the valve body and the frictional force is also reduced. In addition, the underlying part of the guide Construct the wall freely without considering the guiding properties with regard to the gas barrier effect.

Wie aus Fig. 1 ersichtlich, umschließt das Gehäuse 1 eines Füllorganes einen ständig mit Getränk gefüllten Schacht 2, der beispielsweise in üblicher Ausbildung von unten in den Boden eines nicht dargestellten Getränkevorratskessels mündet. Der Boden 3 des Schachtes ist auf der Oberseite eines in das Gehäuse 1 eingesetzten Einsatzteiles 4 ausgebildet, in dem ein Getränkeauslauf 5 vorgesehen ist, der in üblicher Weise nach unten zur Mündung eines nicht dargestellten zu füllenden Behälters führt.As can be seen from FIG. 1, the housing 1 of a filling element encloses a shaft 2 which is constantly filled with drink and which, for example in conventional design, opens from below into the bottom of a beverage storage kettle (not shown). The bottom 3 of the shaft is formed on the top of an insert 4 inserted into the housing 1, in which a beverage outlet 5 is provided, which in the usual way leads down to the mouth of a container (not shown) to be filled.

Im Boden 3 des Schachtes 2 ist in üblicher Weise als Ventilsitz, ringförmig den Getränkeauslauf 5 umgebend, ein Dichtring 6 angeordnet. Gegen diesen kommt der untere Rand eines Ventilkörpers 7 in dichtenden, den Getränkeauslauf 5 gegen den Schacht 2 verschließenden Eingriff, wenn der Ventilkörper 7 gegenüber der in Fig. 1 dargestellten Stellung nach unten abgesenkt ist. Der Ventilkörper 7 ist zu diesem Zweck in nicht dargestellter Weise höhengesteuert im Schacht 2 gelagert.In the bottom 3 of the shaft 2, a sealing ring 6 is arranged in the usual way as a valve seat, annularly surrounding the beverage outlet 5. Against this, the lower edge of a valve body 7 comes into sealing engagement, closing the beverage outlet 5 against the shaft 2, when the valve body 7 is lowered relative to the position shown in FIG. 1. For this purpose, the valve body 7 is mounted in a height-controlled manner in the shaft 2 in a manner not shown.

In üblicher Bauweise ist der dargestellte Ventilkörper 7 von einem Gaskanal 8 durchsetzt, der unterhalb des Ventilkörpers 7 in einem nach unten durch den Getränkeauslauf 5 ragenden Rückluftrohr 9 verlängert ist.In a conventional design, the valve body 7 shown is penetrated by a gas channel 8, which is below the valve body 7 is extended in a return air pipe 9 projecting downward through the beverage outlet 5.

Zur Erleichterung der konstruktiven Verhältnisse an den nicht dargestellten oben liegenden Führungseinrichtungen für den Ventilkörper 7 ist bei der dargestellten Konstruktion der Ventilkörper 7 an seinem unteren Ende in einer Führungswand 10 gelagert. Diese umgibt den Umfang des im dargestellten Ausführungsfall runden Ventilkörpers 7 allseitig mit geringem Spiel und besorgt auf diese Weise eine gute Führung des Ventilkörpers nach Art einer Kolbenzylinderführung.In order to facilitate the structural conditions on the guide devices for the valve body 7, which are not shown above, the valve body 7 in the illustrated construction is mounted at its lower end in a guide wall 10. This surrounds the circumference of the round valve body 7 in the illustrated embodiment with little play on all sides and in this way ensures good guidance of the valve body in the manner of a piston-cylinder guide.

Die Führungswand 10 ist von derartiger Hohe, daß sie dem Ventilkörper 7 auch in seiner obersten Betriebsstellung, die etwas höher liegt als in Fig. 1 dargestellt, noch ausreichende Führung gibt. Sie umschließt den Ventilkörper also ständig und würde den Flüssigkeitsdurchlauf versperren. Daher besitzt sie Öffnungen 11, durch die bei geöffnetem Ventilkörper 7 Flüssigkeit vom Schacht 2 zum Getränkeauslauf 5 fließen kann.The guide wall 10 is of such a height that it gives the valve body 7 sufficient guidance even in its uppermost operating position, which is somewhat higher than that shown in FIG. 1. It therefore constantly encloses the valve body and would block the liquid flow. It therefore has openings 11 through which liquid can flow from the shaft 2 to the beverage outlet 5 when the valve body 7 is open.

Öffnungen 11 sind im Ausführungsfall der Fig. 1 als runde, radial verlaufende Bohrungen ausgebildet. Der Durchmesser dieser Bohrungen ist derart dimensioniert, daß zwar Flüssigkeit hindurchtreten kann, nicht aber Gasblasen. Die Führungswand 11 wirkt also als Gassperre. Bei üblichen Getränken und Gasen, wie beispielsweise Luft oder CO₂ kann der Durchmesser der Öffnung 11 maximal etwa 1 mm betragen, um bei guter Flüssigkeitsdurchströmbarkeit sichere Gassperrwirkung zu gewährleisten.In the embodiment of FIG. 1, openings 11 are designed as round, radially running bores. The diameter of these bores is dimensioned such that liquid can pass through, but not gas bubbles. The guide wall 11 thus acts as a gas barrier. With conventional beverages and gases, such as air or CO₂, the diameter of the opening 11 may be a maximum of about 1 mm in order to ensure safe gas barrier effect with good liquid flow.

Die Führungswand 10 ist im bevorzugten Ausführungsbeispiel auswechselbar im Füllorgan angeordnet. Wie Fig. 1 zeigt, ist sie zu diesem Zweck mit einem Ringfuß 12 versehen, der in einer entsprechenden Nut im Boden des Schachtes 2 einge lassen ist. Der Ringfuß 12 kann dabei, wie Fig. 1 zeigt, gleichzeitig als Sicherung für den Dichtring 6 dienen.In the preferred exemplary embodiment, the guide wall 10 is interchangeably arranged in the filling element. As shown in FIG. 1, for this purpose it is provided with an annular base 12 which is inserted in a corresponding groove in the bottom of the shaft 2 is let. The ring base 12 can, as shown in FIG. 1, also serve as a backup for the sealing ring 6.

Fig. 1a zeigt in Ausschnittsdarstellung aus Fig. 1 nur eine Führungswand 100, bei der anstelle von Bohrungen schlitzförmige Öffnungen 111 ausgebildet sind. Für eine ausreichende Gassperrwirkung muß die Schlitzbreite etwa im Bereich von 1 mm liegen. Die Führungswand 100 ist hier relativ dünn ausgebildet. An ihrem oberen Rand ist ein Ring 110 vorgesehen, der dicker ist, gegenüber der übrigen Führungswand nach innen radial vorspringt und allein zur Führung des Ventilkörpers 7 dient.FIG. 1 a shows a detail from FIG. 1 only one guide wall 100, in which slot-shaped openings 111 are formed instead of bores. For a sufficient gas barrier effect, the slot width must be approximately 1 mm. The guide wall 100 is relatively thin here. At its upper edge, a ring 110 is provided which is thicker, projects radially inwards relative to the rest of the guide wall and is used solely for guiding the valve body 7.

Die Fig. 1b und c zeigen in einer ähnlichen Darstellung wie Fig. 1a weitere Beispiele für Führungswände 100', 100''.1b and c show, in a representation similar to FIG. 1a, further examples of guide walls 100 ', 100' '.

Die Führungswand 100' ist in Form eines oben geschlossenen Kammes mit einem oberen umlaufenden Ring 110' ausgebildet. Die Zwischenräume zwischen den Kammstegen bilden Öffnungen 111'.The guide wall 100 'is designed in the form of a comb closed at the top with an upper circumferential ring 110'. The spaces between the ridge webs form openings 111 '.

Ähnlich ist die Konstruktion der in Fig. 1c abgebildeten siebartigen Führungswand 100'', die ebenfalls einen oberen umlaufenden Ring 110'' aufweist. Die Zwischenräume zwischen den Siebstegen bilden hier Öffnungen 111''.The construction of the screen-like guide wall 100 ″ shown in FIG. 1 c, which likewise has an upper circumferential ring 110 ″, is similar. The spaces between the sieve webs here form openings 111 ″.

Auch bei den Ausführungsformen der Fig. 1b und 1c sind die oberen Ringe 110' bzw. 110'' gegenüber der Führungswand 100' bzw. 100'' radial nach innen vorspringend verdickt und dienen zur Führung des Ventilkörpers 7. In entsprechender Weise kann auch bei der Ausführungsform der Fig. 1 die Wand 11 dünner ausgebildet und mit einem oberen nach innen radial vorspringenden Ring ausgebildet sein, der allein zur Führung des Ventilkörpers 7 dient.1b and 1c, the upper rings 110 'and 110' 'are thickened radially inwardly projecting relative to the guide wall 100' and 100 '' and serve to guide the valve body 7 1, the wall 11 is made thinner and has an upper, radially inwardly projecting ring which is used solely for guiding the valve body 7.

Fig. 2 zeigt eine Führungswand 10' in vergrößerter Darstellung entsprechend dem Schnitt der Fig. 1 (rechts). Die Führungswand 10' weist Öffnungen 11' auf, die entsprechend den Öffnungen 11 der Fig. 1 als Bohrungen ausgebildet sind. Diese sind jedoch, wie Fig. 2 zeigt, von außen nach innen schräg abwärts laufend ausgebildet. Damit wird erreicht, daß die Flüssigkeit, die in diesem Bereich ohnehin von außen nach innen abwärts in Pfeilrichtung strömen muß, ohne Umlenkung strömungsgünstig durch die Öffnungen 11' laufen kann. In entsprechender Weise können auch bei der Ausführungsform der Fig. 1a die Schlitze 111 schräg nach innen abwärts ausgebildet sein. Unabhängig davon können die Schlitze 111, die in Fig. 1a parallel zum Rand 110 verlaufend dargestellt sind, auch schräg zu diesem verlaufend angeordnet sein.Fig. 2 shows a guide wall 10 'in an enlarged view corresponding to the section of Fig. 1 (right). The guide wall 10 'has openings 11' which are designed as bores corresponding to the openings 11 in FIG. 1. However, as shown in FIG. 2, these are designed to run obliquely downwards from the outside inwards. This ensures that the liquid, which in this area must flow downwards in the direction of the arrow from the outside in any case, can flow through the openings 11 'in a flow-favorable manner without deflection. In a corresponding manner, the slots 111 can also be formed obliquely inwards downwards in the embodiment of FIG. 1a. Irrespective of this, the slots 111, which are shown in FIG.
