Description

Die Erfindung betrifft ein Füllorgan der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a filling element of the type mentioned in the preamble of claim 1.

Derartige Füllorgane bilden den heute üblichen Stand der Technik. Üblicherweise ist dabei am Ventilkörper noch ein nach unten in den Behälter ragendes Rückgasrohr vorgesehen, durch das Gas aus dem Behälter entweicht und das, wenn sein unteres Ende vom Füllpegel erreicht wird, das weitere Austreten von rückströmendem Gas verhindert und somit die Füllung stoppt. Es kann auch auf andere Weise, beispielsweise mittels Sensoren, der Füllstand ermittelt und mit einem Rückgasventil das Austreten des Gases unterbrochen werden.Filling elements of this type form the state of the art customary today. Usually, a return gas tube projecting downwards into the container is provided on the valve body, through which gas escapes from the container and which, when its lower end is reached by the filling level, prevents further escape of back-flowing gas and thus stops the filling. The fill level can also be determined in another way, for example by means of sensors, and the escape of the gas can be interrupted with a return gas valve.

Bei Füllorganen der gattungsgemäßen Art ist nach dem Füllstopp durch Unterbrechen des Rückgasstromes das Flüssigkeitsventil noch über einen gewissen Zeitraum geöffnet, der z.B. bei stehendem Getränkefüller sehr lang sein kann. Während dieses Zeitraumes, bevor das Flüssigkeitsventil schließt und weiterer Zustrom in den Behälter endgültig unterbrochen wird, muß verhindert werden, daß Gas auf andere Weise, beispielsweise am Flüssigkeitsventil vorbei aufsteigt und somit weiterhin Flüssigkeit nachströmen kann, da dann der gewünschte Füllpegel im Behälter überschritten würde.In the case of filling devices of the generic type, the liquid valve is still open for a certain period of time after the filling stop by interrupting the return gas flow, which can be very long, for example, when the beverage filler is standing. During this period, before the liquid valve closes and further flow into the container is finally interrupted, it must be prevented that gas rises in another way, for example past the liquid valve and thus liquid can continue to flow, since the desired fill level in the container would then be exceeded.

Zu diesem Zweck ist bei gattungsgemäßen Füllorganen im Bereich des Flüssigkeitsventiles eine Gassperre in Form einer am Ventilkörper gelagerten Glocke vorgesehen. Die Glocke kann mit Spalten gegenüber benachbarten Teilen angeordnet und/oder mit Durchbrechungen ausgebildet sein, die geometrisch derart ausgebildet sind, daß sie zwar Flüssigkeit hindurchlassen, aufgrund der Oberflächenspannung aber den Durchtritt von Gasblasen verhindern und somit die gewünschte Gassperrwirkung erzielen.For this purpose, a gas barrier in the form of a bell mounted on the valve body is provided in the area of the liquid valve in the case of filling organs of the generic type. The bell can be arranged with gaps opposite adjacent parts and / or can be formed with openings which are geometrically designed such that they let liquid pass through, but prevent the passage of gas bubbles due to the surface tension and thus achieve the desired gas barrier effect.

Ein derartiges Füllorgan ist aus dem Patentdokument DE-C-1 162 711 bekannt. Hier ist die Glocke am Ventilkörper zu gemeinsamer Höhenbewegung befestigt. Vorteilhaft daran ist die ständige Bewegung der Glocke, die einen Selbstreinigungseffekt bewirkt. Nachteilig hieran ist, daß der untere Rand der Glocke bei der Abwärtsbewegung in die Schließstellung des Ventilkörpers tief unter den Ventilsitz bewegt wird und somit eine tiefe Rinne außerhalb des Ventilsitzes erforderlich ist.Such a filling element is known from patent document DE-C-1 162 711. Here the bell is attached to the valve body for common height movement. The advantage of this is the constant movement of the bell, which causes a self-cleaning effect. The disadvantage of this is that the lower edge of the bell is moved deeply below the valve seat during the downward movement into the closed position of the valve body, and a deep channel outside the valve seat is therefore required.

Aus dem Patentdokument DE-C-27 27 723 ist weiterhin eine Konstruktion bekannt, bei der die Glocke ortsfest am Füllorgan befestigt ist. Damit werden die Nachteile der vorgenannten Konstruktion beseitigt. Die unübliche Konstruktionsweise schafft aber ebenfalls Nachteile, beispielsweise dadurch, daß die Glocke nicht mehr mit dem Ventilkörper montierbar ist sowie dadurch, daß sie dauernd stillsteht und somit der Selbstreinigungseffekt fehlt.From the patent document DE-C-27 27 723 a construction is also known in which the bell is fixed in place on the filling element. This eliminates the disadvantages of the aforementioned construction. However, the unusual design also creates disadvantages, for example in that the bell can no longer be mounted with the valve body and in that it is constantly at a standstill and the self-cleaning effect is therefore lacking.

Die Aufgabe der vorliegenden Erfindung besteht daher darin, ein Füllorgan der eingangs genannten Art zu schaffen, bei dem die Nachteile bei den bekannten Konstruktionen vermieden werden.The object of the present invention is therefore to create a filling element of the type mentioned in the introduction, in which the disadvantages of the known constructions are avoided.

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

Erfindungsgemäß ist die Glocke am Ventilkörper höhenbeweglich gelagert. In der öffnungsstellung wird sie zwischen den Anschlägen in definierter Höhenlage gehalten, so daß ihr unterer Rand in erforderlicher Weise in definierter Höhenlage über dem Ventilsitz stehen kann, beispielsweise mit einem Ringspalt, der flüssigkeits- aber nicht gasdurchläs-sig ist und somit die erforderliche Gassperrwirkung entfaltet. Da die Glocke höhenbeweglich auf dem Ventilkörper gelagert ist, muß sie nicht dessen volle Abwärtsbewegung bis zur Schließstellung mitmachen, kann also beispielsweise bereits dann auf dem Ventilsitz aufsetzen, wenn der Ventilkörper selbst noch eine größere Abwärtsbewegung bis zum Erreichen des Ventilsitzes ausführen muß. Die Ventilkonstruktion gewinnt dadurch eine Reihe konstruktiver Möglichkeiten, die bisher nicht vorhanden waren. Sie kann besser als bisher hinsichtlich der Flüssigkeitsdurchströmbarkeit und der Gassperrwirkung optimiert werden. Außerdem läßt sich die Glocke als selbständiges nur lose geführtes Teil kostengünstiger, beispielsweise als Blechpreßteil, herstellen. Die Montage der Glocke im Füllorgan kann in gewohnter Weise nach Anbringen am Ventilkörper zusammen mit diesem erfolgen. Sie wird außerdem ständig bewegt und reinigt sich dadurch ständig selbst. Ferner läßt sich auf diese Weise bei ansonsten einheitlicher Konstruktion des Füllorganes sehr einfach die Gassperre den individuellen Anforderungen eines Kunden anpassen.According to the bell is mounted on the valve body so that it can move in height. In the open position, it is held between the stops at a defined height, so that its lower edge can be positioned above the valve seat at a defined height in the required manner, for example with an annular gap that is liquid but not gas permeable and thus has the required gas barrier effect . Since the bell is mounted on the valve body in such a way that it can move vertically, it does not have to go along with its full downward movement until the closed position, so it can, for example, touch the valve seat when the valve body itself has to carry out a larger downward movement until it reaches the valve seat. As a result, the valve construction gains a number of design options that were not previously available. It can be optimized better than before with regard to the fluid flow and the gas barrier effect. In addition, the bell can be produced more cost-effectively as an independent, loosely guided part, for example as a pressed sheet metal part. The bell can be installed in the filling element in the usual way after being attached to the valve body together with the latter. It is also constantly moved and therefore constantly cleans itself. Furthermore, with an otherwise uniform construction of the filling element, the gas barrier can be very easily adapted to the individual requirements of a customer.

Weiterhin vorteilhaft sind die Merkmale des Anspruches 2 vorgesehen. Auf diese Weise wird die Glocke in der Öffnungsstellung auf ihrem Umfang allseitig sicher gehalten, und zwar unabhängig von ihrer Winkellage. Dadurch wird ihre exakte Stellung zu Zwecken sicherer Gassperrwirkung sichergestellt.The features of claim 2 are also advantageously provided. In this way, the bell is securely held on all sides in its open position, regardless of its angular position. This ensures their exact position for the purpose of a safe gas barrier effect.

Weiterhin vorteilhaft sind die Merkmale des Anspruches 3 vorgesehen. Auf diese Weise kann die Glocke in kostengünstiger Weise mit vielen Löchern versehen werden, die bei gassperrender Größe den Flüssigkeitsdurchsatz erhöhen.The features of claim 3 are also advantageously provided. In this way, the bell can be provided with many holes in a cost-effective manner, which increase the liquid throughput when the gas is blocked.

Weiterhin vorteilhaft sind die Merkmale des Anspruches 4 vorgesehen. Auf diese Weise kann der die Durchbrechungen der Glocke durchstromenden Flüssigkeit ein Drall um die Ventilachse aufgeprägt werden, der bekanntlich zu ruhigem Einströmen der Flüssigkeit in den zu füllenden Behälter von Vorteil ist.The features of claim 4 are also advantageously provided. In this way, a swirl about the valve axis can be imparted to the liquid flowing through the openings in the bell, which is known to be advantageous for smooth flow of the liquid into the container to be filled.

In der Zeichnung ist die Erfindung beispielsweise im Schnitt durch ein Füllorgan dargestellt.In the drawing, the invention is shown, for example, in section through a filling element.

Unter einer Öffnung eines Getränkevorratskessels 1 ist ein Füllorgan 2 mit nicht dargestellten Mitteln befestigt. Der Auslauf 3 des Füllorganes ist mit einer Dichtung 4 auf dem Rand einer Flasche 5 abgedichtet.A filling element 2 is fastened under an opening of a beverage storage kettle 1 by means not shown. The outlet 3 of the filling element is sealed with a seal 4 on the edge of a bottle 5.

Im Innenraum 6 des Füllorganes ist ein Ventilkörper 7 höhenbeweglich angeordnet. Der Ventilkörper 7 ist nach oben und nach unten mit einem Rückgasrohr 8 verlängert, dessen Gaskanal den Ventilkörper 7 durchsetzt.In the interior 6 of the filling element, a valve body 7 is arranged such that it can move in height. The valve body 7 is extended upwards and downwards with a return gas tube 8, the gas channel of which passes through the valve body 7.

Der Ventilkörper 7 trägt einen Dichtring 9, der in der untersten Stellung des Ventilkörpers 7 in dichtender Anlage auf dem Ventilsitz 10 des Füllorganes 2 liegt.The valve body 7 carries a sealing ring 9 which, in the lowest position of the valve body 7, lies in sealing contact on the valve seat 10 of the filling element 2.

In der Figur sind Ventilkörper 7 und Rückgasrohr 8 jeweils links bzw. rechts von der Mittellinie in unterschiedlichen Betriebsstellungen dargestellt. Auf der rechten Seite ist die Schließstellung dargestellt, in der der Ventilkörper 7 dichtend auf dem Ventilsitz 10 aufliegt. Auf der linken Seite ist die Öffnungsstellung dargestellt, in der der Ventilkörper angehoben ist. Es sind nicht dargestellte Mittel vorgesehen, die beispielsweise am nichtdargestellten oberen Ende des Rückgasrohres 8 angreifen, um den Ventilkörper 7 zwischen den beiden dargestellten Betriebsstellungen zu bewegen. Diese Mittel können beispielsweise aus einer bei Gleichdruck öffnenden Feder bestehen oder aus von außen zu betätigenden Hebeln.In the figure, valve body 7 and return gas tube 8 are shown in different operating positions on the left and right of the center line, respectively. The closed position is shown on the right-hand side, in which the valve body 7 lies sealingly on the valve seat 10. The opening position, in which the valve body is raised, is shown on the left-hand side. It is not shown Provided, for example, to attack the upper end of the return gas pipe 8, not shown, to move the valve body 7 between the two operating positions shown. These means can consist, for example, of a spring that opens at constant pressure or of levers that can be actuated from the outside.

Im Innenraum 6 des Füllorganes 2 ist ein Anschlagring 11 feststehend montiert, der an seiner unteren Ringfläche einen Festanschlag 12 ausbildet. Am Ventilkörper 7 ist eine nach oben weisende Ringfläche ausgebildet, die als Ventilanschlag 13 dient. Die Öffnungsbewegung des Ventilkörpers nach oben wird in der in der linken Hälfte der Figur dargestellten Öffnungsstellung durch Anschlag des Ventilanschlages 13 gegen den Festanschlag 12 begrenzt.A stop ring 11 is fixedly mounted in the interior 6 of the filling element 2 and forms a fixed stop 12 on its lower ring surface. An upwardly facing annular surface is formed on the valve body 7, which serves as a valve stop 13. The opening movement of the valve body is limited in the opening position shown in the left half of the figure by the valve stop 13 abutting against the fixed stop 12.

Oberhalb des Ventilanschlages 13 ist auf dem Ventilkörper 7 eine Glocke 14 frei höhenbeweglich gelagert. Die Glocke 14 ist dazu in der Grundform eines Ringes mit einem großen inneren Loch 27 ausgebildet, das mit Spiel auf dem Umfang des Ventilkörpers 7 sitzt. Die Glocke ist im dargestellten Fall mit einer Vielzahl von Löchern 15 versehen. Im bevorzugten Ausführungsbeispiel ist sie aus einem Lochblech als Ring ausgestanzt und in die dargestellte Glockenform gepreßt.Above the valve stop 13, a bell 14 is freely movable on the valve body 7. The bell 14 is designed in the basic form of a ring with a large inner hole 27 which sits with play on the circumference of the valve body 7. The bell is provided with a plurality of holes 15 in the case shown. In the preferred embodiment, it is punched out of a perforated sheet as a ring and pressed into the bell shape shown.

Wie der Vergleich der beiden Hälften der Figur zeigt, wird die Glocke 14 in der links dargestellten Öffnungsstellung zwischen dem Ventilanschlag 13 und dem Festanschlag 12 fest eingespannt, wozu sie auf ihre Ober- und Unterseite entsprechend ausgebildete ringförmige Anschlagflächen aufweist, und wird somit auf einer definierten Höhe gehalten, in der sie mit dem dargestellten Abstand über dem Ventilsitz steht. Dieser Abstand ergibt einen Spalt, der in einer Größe von einigen Zehntel Millimetern derart gewählt ist, daß Flüssigkeit hindurchfließen, aber keine Gasblasen hindurchtreten können. Ebenso sind die Löcher 15 im erwähnten Größenbereich eingestellt, daß sie ebenfalls Flüssigkeit hindurchtreten lassen aber keine Gasblasen.As the comparison of the two halves of the figure shows, the bell 14 is firmly clamped in the open position shown on the left between the valve stop 13 and the fixed stop 12, for which purpose it has correspondingly shaped annular stop surfaces on its upper and lower sides, and is thus on a defined one Height held at the distance shown above the valve seat. This distance results in a gap which is chosen in a size of a few tenths of a millimeter such that liquid can flow through it, but no gas bubbles can pass through it. Likewise, the holes 15 are mentioned Size range set that they also let liquid pass through but no gas bubbles.

In der rechts dargestellten Schließstellung des Ventils ist die Glocke 14 frei. Sie steht auf dem Ventilsitz auf und muß nicht die gesamte Abwärtsbewegung des Ventilkörpers 7 mitmachen.In the closed position of the valve shown on the right, the bell 14 is free. It stands on the valve seat and does not have to participate in the entire downward movement of the valve body 7.

Der Ventilsitz ist zur Verdeutlichung einer Variante in den beiden Hälften der Figur unterschiedlich dargestellt. Auf der rechten Seite bildet der Ventilsitz 10 einen Siphon üblicher Konstruktion aus, wobei die Glocke in den Kanal 16 des Siphons ragt.The valve seat is shown differently in the two halves of the figure to illustrate a variant. On the right side, the valve seat 10 forms a siphon of conventional construction, the bell protruding into the channel 16 of the siphon.

Auf der linken Seite der Figur ist der Ventilsitz 10' eben ausgebildet, also ohne Ausbildung eines Siphons.On the left side of the figure, the valve seat 10 'is flat, that is, without the formation of a siphon.

Die Wirkungsweise der dargestellten Konstruktion wird wie folgt erläutert:
In der rechts dargestellten Schließstellung des Füllorganes steht die Flüssigkeit aus dem Vorratskessel 1 im Innenraum 6 des Füllorganes oberhalb des geschlossenen Ventiles. Jetzt kann an der Unterseite des Füllorganes eine neue Flasche 5 oder gegebenenfalls bei etwas anderer Gestaltung des Füllorganes eine zu füllende Dose angesetzt werden.The operation of the construction shown is explained as follows:
In the closed position of the filling element shown on the right, the liquid from the storage vessel 1 is in the interior 6 of the filling element above the closed valve. Now a new bottle 5 or, if necessary, a can to be filled with a slightly different design of the filling element can be attached to the underside of the filling element.

Durch das Rückgasrohr 8 oder auf andere Weise wird, falls es sich um karbonisierte Getränke handelt, der Behälter vorgespannt. Sodann wird das Flüssigkeitsventil durch Heben des Ventilkörpers 7 in die auf der linken Seite der Figur dargestellte Öffnungsstellung geöffnet. Jetzt strömt (linke Seite der Figur) Flüssigkeit durch die Löcher 15 der Glocke 14 bzw. durch den Spalt, der unter deren Rand ausgebildet ist. Die Flüssigkeit strömt solange in die Flasche 5, bis der Flüssigkeitsspiegel das untere Ende des Rückgasrohres 8 erreicht oder auf andere Weise, beispielsweise mittels Sensoren, festgestellt wird. Durch Versperren des Rückgasweges wird nun der Füllvorgang gestoppt. Da kein Gas mehr aus der Flasche 5 entweichen kann, kann auch keine Flüssigkeit mehr in den Behälter strömen.The container is prestressed by the return gas pipe 8 or in another way, if it is carbonated beverages. The liquid valve is then opened by lifting the valve body 7 into the open position shown on the left side of the figure. Now liquid (left side of the figure) flows through the holes 15 of the bell 14 or through the gap which is formed under the edge thereof. The liquid flows into the bottle 5 until the liquid level reaches the lower end of the return gas pipe 8 or in another way, for example by means of Sensors. The filling process is now stopped by blocking the return gas path. Since no more gas can escape from the bottle 5, no more liquid can flow into the container.

Gas aus dem nicht befüllten Kopfraum des Behälters und aus dem Auslauf 3 könnte aber am noch geöffneten Flüssigkeitsventil vorbei nach oben strömen. Dann würde weitere Flüssigkeit nach unten gelangen können.However, gas from the unfilled head space of the container and from the outlet 3 could flow upwards past the still open liquid valve. Then more liquid would get down.

Dies verhindert die als Gassperre dienende Glocke 14. Diese läßt zwar durch ihre Öffnungen 15 und unter ihrem Rand hindurch Flüssigkeit strömen, ist aber hinsichtlich Spaltgröße und Lochdurchmesser so dimensioniert, daß kein Gas aufsteigen kann. Die Flüssigkeit bleibt also solange gestoppt, bis das Flüssigkeitsventil durch Abwärtsbewegung des Ventilkörpers 7 geschlossen und damit der Flüssigkeitszulauf endgültig unterbrochen wird.This prevents the bell 14 serving as a gas barrier. Although this allows liquid to flow through its openings 15 and below its edge, it is dimensioned with respect to the gap size and hole diameter in such a way that no gas can rise. The liquid thus remains stopped until the liquid valve is closed by moving the valve body 7 downward and the liquid supply is thus finally interrupted.

In einer nicht dargestellten Ausführungsvariante können die Öffnungen 15 der Glocke 14 als drallerzeugende Durchbrechungen ausgebildet sein, die die Flüssigkeit also nur mit tangentialer Strömungskomponente durchtreten lassen. Wenn beim Füllvorgang die Flüssigkeit diese drallerzeugenden Durchbrechungen durchströmt, wird ihr ein Drall um die Ventilachse aufgeprägt. Die Flüssigkeit strömt dann kreisend an der Wand des Auslaufes 3 und an der Wand der Flasche 5 abwärts. Dadurch wird die Einströmung in die Flasche beruhigt, was insbesondere bei stark schäumenden Flüssigkeiten von Vorteil ist.In an embodiment variant, not shown, the openings 15 of the bell 14 can be designed as swirl-generating openings, which therefore only allow the liquid to pass through with a tangential flow component. When the liquid flows through these swirl-producing openings during the filling process, a swirl is impressed around the valve axis. The liquid then flows in a circle down the wall of the outlet 3 and on the wall of the bottle 5. This calms down the inflow into the bottle, which is particularly advantageous for highly foaming liquids.
