Abstract

An easy to use system for connecting a bottle-type, gas containing pressurized vessel to a gas-withdrawal unit includes a valve assembly mounted on the pressurized vessel. A longitudinal axis of this valve assembly is substantially perpendicular to a longitudinal axis of the pressurized vessel resulting in an offset outlet design. The system also includes a housing with slotted links for guiding and holding the pressurized vessel as well as a centering device located in front of the gas-withdrawal unit for aiding alignment of an outlet of the valve assembly with an inlet port of the gas-withdrawal unit. A pivot lever is also provided to press and hold the outlet of the valve assembly gastight against the inlet port of the control unit.

Description

Die vorliegende Erfindung bezieht sich auf eine Anordnung zum steckbaren Anflan­schen eines flaschenartig ausgebildeten, unter Druck stehenden, Gas enthaltenden Druckbehälters mit einer steuerbaren Ventileinrichtung unter Verwendung einer An­druckeinrichtung an eine Gasentnahme-Einrichtung mit einer Steuereinrichtung zum Regeln des Druckes des entnommenen Gases, wobei die Steuereinrichtung der Gas­entnahme-Einrichtung mit der Ventileinrichtung des Druckbehälters zusammenwirkt.The present invention relates to an arrangement for the pluggable flange-mounting of a bottle-shaped, pressurized, gas-containing pressure vessel with a controllable valve device using a pressure device on a gas extraction device with a control device for regulating the pressure of the withdrawn gas, the control device of the Gas extraction device cooperates with the valve device of the pressure vessel.

Derartige Anordnungen können beispielsweise Anwendung finden in Getränkeautoma­ten, durch welche Getränkekonzentrate mit Sodawasser zu einem Erfrischungsgetränk gemischt werden. Bei derartigen Geräten wird das Sodawasser durch Anreichern von Frischwasser mit CO₂-Gas in einem bevorzugterweise gekühlten Vorratsgefäß be­wirkt. Für den individuellen Einsatz derartiger Geräte ist es zweckmäßig und wün­schenswert, die Auswechselbarkeit auch der CO₂-Vorratsbehälter möglichst einfach und damit für jedermann durchführbar zu ermöglichen. Üblicherweise werden die CO₂-Vorratsbehälter mit der Gasentnahme-Einrichtung verschraubt. Es ist aber auch bekannt, den CO₂-Druckbehälter durch eine Steckverbindung mit der Gasentnahme-­Einrichtung zu verbinden und diese Verbindung dadurch aufrecht zu erhalten, daß über diesen Vorratsbehälter ein entsprechender Anpreßdruck geleitet wird.Such arrangements can be used, for example, in vending machines, by means of which beverage concentrates are mixed with soda water to form a soft drink. In such devices, the soda water is brought about by enriching fresh water with CO₂ gas in a preferably cooled storage vessel. For the individual use of such devices, it is expedient and desirable to make the interchangeability of the CO₂ storage containers as simple as possible and thus feasible for everyone. Usually, the CO₂ storage container is screwed to the gas sampling device. But it is also known to connect the CO₂ pressure vessel through a plug-in connection with the gas sampling device and to maintain this connection in that a corresponding contact pressure is passed through this reservoir.

Bei den bekannten Anordnungen treten zwei Hauptprobleme auf. Das eine Problem besteht darin, daß beim Zusammenführen der Flansche einerseits des Vorratsbehäl­ters und andererseits der Gasentnahme-Einrichtung hohe Sorgfalt geübt werden muß, da dabei leicht in diesem Bereich Beschädigungen auftreten können. Solche Be­schädigungen führen aber dann meist zu Gasundichtigkeiten. Das zweite Problem ist darin zu sehen, daß bei den bekannten Steckverbindungen der Anpreßdruck über die gesamte Gasflasche geleitet wird, was ein entsprechend stabiles Gehäuse voraus­setzt, welches diese Kräfte aufnehmen kann und zum anderen hohe Ansprüche an die Fertigungsgenauigkeit stellt. Dieses Problem ist über elastische Andruckmittel, bei­spielsweise über Federdruck, nur bedingt lösbar, da bei zu großzügiger Anwendung dieser Maßnahmen nicht eine ausreichende Sicherheit für eine zuverlässige Verbin­dung zwischen den beiden Flanschteilen gegeben ist.There are two main problems with the known arrangements. One problem is that great care must be taken when merging the flanges on the one hand of the storage container and on the other hand of the gas extraction device, since damage can easily occur in this area. Such damage usually leads to gas leaks. The second problem is to be seen in the fact that the contact pressure is passed over the entire gas bottle in the known plug connections, which requires a correspondingly stable housing which can absorb these forces and, on the other hand, places high demands on the manufacturing accuracy. This problem can only be solved to a limited extent using elastic pressure means, for example spring pressure, since if these measures are used too generously, there is insufficient security for a reliable connection between the two flange parts.

Der vorliegenden Erfindung liegt nunmehr die Aufgabe zugrunde, eine Anordnung zum steckbaren Anflanschen eines flaschenartig ausgebildeten Druckbehälters mit einer Gasentnahme-Einrichtung bereitzustellen, bei welcher trotz einfachen Aufbaus eine einfache Bedienbarkeit und eine funktionssichere Verbindung gewährleistet ist.The present invention is based on the object of providing an arrangement for the pluggable flange-mounting of a bottle-shaped pressure vessel with a gas extraction device, in which simple operability and a functionally reliable connection is ensured despite the simple construction.

Eine Anordnung, welche diesen gestellten Aufgaben im besonderen Maße gerecht wird, ist erfindungsgemäß dadurch gekennzeichnet, daß an der Gasentnahme-Einrich­tung ein handbetätigbarer Schwenkhebel gelagert ist, über welchen die Ventileinrich­tung des Druckbehälters an Betätigungsflanschen erfaßbar und gegen die Anschluß­öffnung der Entnahmeeinrichtung anpreßbar ist.An arrangement which particularly fulfills these tasks is characterized in that a manually operable pivot lever is mounted on the gas extraction device, by means of which the valve device of the pressure vessel can be detected on actuating flanges and can be pressed against the connection opening of the extraction device.

Eine nach diesen erfindungsgemäßen Merkmalen ausgestaltete Anordnung entspricht den an sie gestellten Anforderungen insoweit, daß über den handbetätigbaren, an der Gasentnahme-Einrichtung angelenkten Schwenkhebel die Ventileinrichtung über die Betätigungsflansche erfaßbar und gegen die Anschlußöffnung der Entnahmeeinrichtung anpreßbar ist. Damit findet der Kraftverlauf zur Erzielung des Anpreßdruckes ledig­lich im unmittelbaren Nahbereich der zusammenzufügenden Flanschteile statt. Be­schädigungen der Flanschteile werden dadurch weitestgehend vermieden. Infolge der relativ kurzen, zu überbrückenden Abstände kann auf elastische Anpreßmittel zum Toleranzausgleich weitestgehend verzichtet werden, so daß Beschädigungen im Flanschbereich sich mit großer Wahrscheinlichkeit dahin auswirken, daß dies beim Anflanschvorgang durch erschwerte, bzw. nicht durchführbare Betätigungsbedingungen erkennbar ist. Damit wird die Bedienungsperson auf fehlerhafte Bedingungen in den Flanschbereichen, welche sich auch als Verschmutzungen darstellen können, aufmerk­sam gemacht.An arrangement designed according to these features according to the invention meets the requirements placed on them to the extent that the valve device can be grasped via the actuating flanges and pressed against the connection opening of the removal device by means of the manually actuable pivot lever articulated on the gas removal device. The force curve to achieve the contact pressure therefore only takes place in the immediate vicinity of the flange parts to be joined. This largely prevents damage to the flange parts. As a result of the relatively short distances to be bridged, elastic pressing means for tolerance compensation can largely be dispensed with, so that damage in the flange area has a high probability that this will affect the Flange operation can be recognized by difficult or not feasible operating conditions. This draws the operator's attention to faulty conditions in the flange areas, which can also present themselves as dirt.

Aus kraftübertragungs-technischen Gründen ist es zweckmäßig, daß der Anflanschbe­reich zwischen der Entnahmeeinrichtung und der Ventileinrichtung zwischen der La­gerstelle des Schwenkhebels an der Entnahmeeinrichtung und der Betätigungsflächen der Ventilanordnung für den Schwenkhebel angeordnet ist.For reasons of power transmission, it is expedient that the flange area between the removal device and the valve device is arranged between the bearing point of the pivot lever on the removal device and the actuating surfaces of the valve arrangement for the pivot lever.

Nach einer bevorzugten Ausgestaltung ist diese erfindungsgemäße Anordnung dadurch gekennzeichnet, daß seitlich gegenüberliegend an der Ventileinrichtung Betätigungs­ansätze für den Schwenkhebel der Entnahmeeinrichtung angeordnet sind. Hiermit sind in einfacher Weise Angriffspunkte für den durch den handbetätigbaren Schwenkhe­bel realisierten Anpreßmechanismus geschaffen. Eine weitere Verbesserung der Funktionstüchtigkeit der erfindungsgemäßen Anordnung ist dadurch erzielbar, daß zwischen der Ventileinrichtung und dem Schwenkhebel zwei Angriffsbereiche ange­ordnet sind. Über den einen Angriffsbereich, über welchen eine längerhubige Annä­herung zwischen Ventileinrichtung und Entnahmeenirichtung erzielbar ist, werden die Ventilsitze in einer ersten Schwenkphase des Schwenkhebels gegeneinander in die Arbeitslage bewegt, während über den zweiten Angriffsbereich endgültig und zuver­lässig kurzhubig die Arbeitslage mit dem erforderlichen Anpreßdruck erzielbar ist. Eine zusätzliche Verbesserung der erfindungsgemäßen Anordnung ist dann gegeben, wenn zwischen Ventileinrichtung und Entnahmeeinrichtung ein kurzhubig wirkendes federndes Zwischenglied angeordnet ist. Dieses federnde Zwischenglied läßt sich un­mitttelbar im Schwenkhebel bevorzugterweise anordnen.According to a preferred embodiment, this arrangement according to the invention is characterized in that actuating lugs for the pivoting lever of the removal device are arranged on the side opposite the valve device. In this way, points of attack are created in a simple manner for the pressing mechanism implemented by the manually actuable pivoting lever. A further improvement in the functionality of the arrangement according to the invention can be achieved in that two engagement areas are arranged between the valve device and the pivoting lever. The valve seats are moved against each other into the working position in a first swiveling phase of the swivel lever over the one attack area, over which a longer-stroke approach between the valve device and removal direction can be achieved, while the working position can be finally and reliably short-stroke with the required contact pressure achieved via the second attack area. An additional improvement of the arrangement according to the invention is given if a short-stroke resilient intermediate member is arranged between the valve device and the removal device. This resilient intermediate member can preferably be arranged directly in the pivot lever.

Als zusätzliche Maßnahme zum Schutz der Flanschteile ist die erfindungsgemäße An­ordnung bevorzugterweise dadurch gekennzeichnet, daß innerhalb eines Außenrohrstut­zens im Bereich der Anschlußöffnung der Ventileinrichtung ein weiterer Zentrier­rohrstutzen der Ventileinrichtung zum Anschluß an die Entnahmeeinrichtung ange­ordnet ist.As an additional measure to protect the flange parts, the arrangement according to the invention is preferably characterized in that a further centering pipe socket of the valve device for connection to the removal device is arranged within an outer pipe socket in the region of the connection opening of the valve device.

Ein nach den Merkmalen der Erfindung ausgestaltetes Ausführungsbeispiel ist anhand der Zeichnung im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 eine Seitenansicht einer Gasentnahme-Einrichtung in Verbindung mit ei­nem an diese angeflanschten Gas-Druckbehälter in einem Gerätege­häuse, teilweise geschnitten,
  • Fig. 2 eine Draufsicht auf diese Anordnung in teilweiser Schnittdarstellung und
  • Fig. 3 eine Anischt in Richtung auf den Aufnahmeflansch der Gastentnahme-­Einrichtung.
An embodiment designed according to the features of the invention is described in more detail below with reference to the drawing. Show it:
  • 1 is a side view of a gas extraction device in connection with a gas pressure container flanged to it in a device housing, partly in section,
  • Fig. 2 is a plan view of this arrangement in partial section and
  • Fig. 3 shows a mixture in the direction of the receiving flange of the guest removal device.

Die dargestellte Anordnung dient zur Entnahme von CO₂-Gas aus einem Druckbehäl­ter 1 über eine Gastentnahme-Einrichtung 2 für einen Karbonisator eines Getränke­automanten. In diesem Karbonisator wird Frischwasser mit dem CO₂-Gas angereich­ert.The arrangement shown serves for the removal of CO₂ gas from a pressure vessel 1 via a guest extraction device 2 for a carbonator of a beverage machine. In this carbonator, fresh water is enriched with the CO₂ gas.

Die Gasentnahme-Einrichtung 2 enthält Regelglieder, welche in Verbindung mit ei­nem Ventilstößel einer an dem Gas-Druckbehälter 1 angeordneten Ventileinrichtung 3 den innerhalb des Gas-Druckbehälters 1 herrschenden Gasdruck auf den im Karbo­nisator benötigten Betriebsdruck geregelt reduzieren. Die Gasentnahme-Einrichtung 2 ist im Gerätegehäuse 4 befestigt und damit Bestandteil des Geräts. Der Gas-Druck­behälter 1 und die Ventileinrichtung 3 bilden eine Funktionseinheit, welche für die Versorgung des Karbonisators mit CO₂-Gas an die Gasentnahme-Einrichtung 2 anzu­flanschen ist.The gas extraction device 2 contains control elements which, in conjunction with a valve tappet of a valve device 3 arranged on the gas pressure container 1, regulately reduce the gas pressure prevailing within the gas pressure container 1 to the operating pressure required in the carbonator. The gas sampling device 2 is fastened in the device housing 4 and is therefore part of the device. The gas pressure vessel 1 and the valve device 3 form a functional unit which is flanged to the gas extraction device 2 for supplying the carbonizer with CO₂ gas.

Zur Bedienungserleichterung und -vereinfachung ist zu diesem Zweck die Ventilein­richtung 3 gekröpft ausgebildet, d.h. ihr Anschlußflansch für die Gasentnahme-Ein­richtung 2 ist gegenüber der Achse des Gas-Druckbehälters 1 rechtwinklig abge­winkelt. Daraus ergibt sich für den Anschluß des Gas-Druckbehälters 1 über die Ventilanordnung 3 an die Gasentnahme-Einrichtung 2 eine Anschlußbewegungsfolge in zwei Stufen. Ein neu in das Gerät einzubringender und anzuschließender Gas-Druck­behälter 1 wird durch die Gehäuseöffnung 5 mit seinem unteren Ende 6 voran in die Aufnahmekammer 7 für den Druckbehälter 1 im wesentlichen in Achsrichtung des Gas-Druckbehälters 1 eingeführt. Geführt durch die Wandabschnitte 8, 9 wird dabei der Gas-Druckbehälter 1 um die Rundkante 10 innerhalb des Gerätegehäuses 4 zwangsläufig in eine Lage verschwenkt und gebracht, bei der die Ventilanordnung 3 in den Bereich der Gasentnahme-Einrichtung 2 gelangt.To facilitate and simplify operation, the valve device 3 is cranked for this purpose, ie its connecting flange for the gas extraction device 2 is angled at right angles to the axis of the gas pressure container 1. This results in a connection movement sequence in two stages for the connection of the gas pressure container 1 via the valve arrangement 3 to the gas extraction device 2. A gas pressure container 1 which is to be introduced and connected to the device is inserted through the housing opening 5 with its lower end 6 in the front Receiving chamber 7 for the pressure vessel 1 is introduced essentially in the axial direction of the gas pressure vessel 1. Passed through the wall sections 8, 9, the gas pressure container 1 is inevitably pivoted and brought about the round edge 10 within the device housing 4 into a position in which the valve arrangement 3 reaches the area of the gas extraction device 2.

Dieser Gasentnahme-Einrichtung 2 vorgelagert ist eine Zentriervorrichtung 11, über welche das abgewinkelte Teilstück der Ventilvorrichtung 3 erfaßt wird, so daß der Anschlußflansch der Ventileinrichtung 3 mit dem komplementären Anschlußflansch der Gasentnahme-Einrichtung 2 zentriert wird. Zu diesem Zweck ist die der Gasent­nahme-Vorrichtung 2 vorgelagerte Zentriervorrichtung 11 - wie in Fig. 3 dargestellt - nach oben hin offen U-förmig ausgestaltet, so daß sie beim Einschieben des Gas-Druckbehälters 1 den abgekröpften, in Fig. 3 strichpunktiert angedeuteten Keil 12 der Ventileinrichtung erfaßt, bis dieser am Boden dieser Zentriereinrichtung 11 zur Anlage kommt. Die Einbaulage des Gas-Druckbehälters 1 ist so gewählt, daß dessen Schwerpunkt dabei im wesentlichen unterhalb dieses Auflagepunkts zwischen Zentriervorrichtung 11 und abgekröpften Teil 12 der Ventileinrichtung liegt. Diese vorzentrierte Arbeitslage ist also im wesentlichen stabil.Upstream of this gas sampling device 2 is a centering device 11, via which the angled section of the valve device 3 is detected, so that the connecting flange of the valve device 3 is centered with the complementary connecting flange of the gas sampling device 2. For this purpose, the upstream of the gas sampling device 2 centering device 11 - as shown in Fig. 3 - is open at the top U-shaped, so that when the gas pressure container 1 is inserted, the cranked wedge, indicated by dash-dotted lines in Fig. 3 12 of the valve device until it comes to rest on the bottom of this centering device 11. The installation position of the gas pressure vessel 1 is selected so that its center of gravity lies essentially below this support point between the centering device 11 and the bent part 12 of the valve device. This pre-centered work situation is essentially stable.

Aus dieser Arbeitslage ist die gasdichte Verbindung zwischen den Flanschteilen der Ventileinrichtung 3 und der Gasentnahme-Einrichtung 2 herbeizuführen. Dazu dient ein handbetätigbarer Schwenkhebel 13, welcher auf Achsansätzen 14 der Gasentnah­me-Einrichtung 2 schwenkbar gelagert ist. In den Figuren 1 und 3 ist die Arbeitsla­ge des Schwenkhebels 13 dargestellt. Dieser greift über angeschrägte Betätigungsflä­chen 15 an Betätigungsansätzen 16 der Ventileinrichtung 3 an. Durch die von oben herab durchgeführte Schwenkbewegung des handbetätigten Schwenkhebels 13 werden dabei die korrespondierenden Flanschteile der Ventileinrichtung 3 und der Gasent­nahme-Einrichtung 2 axial zusammengefügt. Der endgültige Anpreßdruck für diese Funktionsteile wird durch ein im Schwenkhebel 13 angeordnetes Federelement 17 ausgeübt, welches über einen Druckbolzen auf die dem Anschlußflansch der Ven­tileinrichtung 3 gegenüberliegende Ventilpartie auf die Ventileinrichtung 3 wirkt. In dieser Stellung wird über diesen Bolzen 18 der Schwenkhebel 13 hinter einer Erhö­hung der Ventileinrichtung 3 auch kraftschlüssig verrastet.The gas-tight connection between the flange parts of the valve device 3 and the gas extraction device 2 can be brought about from this working position. For this purpose, a manually operable pivot lever 13 is used, which is pivotably mounted on axle lugs 14 of the gas sampling device 2. In Figures 1 and 3, the working position of the pivot lever 13 is shown. The latter engages actuating projections 16 of the valve device 3 via beveled actuating surfaces 15. The corresponding flange parts of the valve device 3 and the gas extraction device 2 are axially joined by the swiveling movement of the manually operated swiveling lever 13 from above. The final contact pressure for these functional parts is exerted by a spring element 17 arranged in the swivel lever 13, which acts on the valve device 3 via a pressure bolt on the valve part opposite the connecting flange of the valve device 3. In this position, the pivot lever 13 is also non-positively locked by means of this pin 18 behind an increase in the valve device 3.
