Description

Die Erfindung betrifft eine Vorrichtung zur Abgabe von Bier, mit einer Zapfstelle, die über eine Zapfleitung mit einem Biervorrat in Verbindung steht, der mehrere voneinander getrennte Behälter aufweist, die an eine Druckgasquelle angeschtossen und über zugehörige Ausgangsleitungen sowie eine mit einer Steuereinrichtung verbundene Umschalteinrichtung nacheinander mit der Zapfleitung in Verbindung setzbar sind.The invention relates to a device for dispensing beer, with a tap which is connected via a tap to a beer supply which has a plurality of separate containers which are connected to a pressurized gas source and, via associated output lines and a switching device connected to a control device, in succession the tap line can be connected.

Bei bekannten Vorrichtungen dieser Art sind die Ausgangsleitungen der einzelnen Bierbehälter über die Umschalteinrichtung an einen Zwischenbehälter angeschlossen, der mit Sonden ausgestattet ist, welche der Steuereinrichtung das Leerwerden des Behälters anzeigen. Mittels der Steuereinrichtung werden sodann als Magnetventile ausgebildete Umschaltventile betätigt, welche die Ausgangsleitung des jeweils leergewordenen Behälters unterbrechen bzw. die Ausgangsleitung des nächsten vollen Behälters freigeben. Der Nachteil dieser Konstruktion besteht darin, daß der Zwischenbehälter aus hygienischen Gründen periodisch gereinigt werden muß, was mit einem beträchtlichen Arbeitsaufwand verbunden ist und eine längere Betriebsunterbrechung bedingt. Durch die Verwendung von Magnetventilen ergibt sich außerdem der Nachteil, daß sich die Magnetventile im betriebsbereiten Zustand erwärmen, so daß das Bier, wenn längere Zeit nicht gezapft wird, auf eine Leitungslänge von z.B. 0,5 m eine Temperatur bis zu 40° C erreichen kann. Dabei findet aber eine Entbindung der Kohlensäure des Bieres und somit ein Qualitätsverlust statt.In known devices of this type, the output lines of the individual beer containers are connected via the switching device to an intermediate container which is equipped with probes which indicate to the control device that the container is emptying. Switching valves designed as solenoid valves are then actuated by means of the control device, which interrupt the output line of the emptied container or release the output line of the next full container. The disadvantage of this construction is that the intermediate container must be cleaned periodically for hygienic reasons, which is associated with a considerable amount of work and a longer downtime. The use of solenoid valves also has the disadvantage that the solenoid valves heat up in the ready state, so that the beer can reach a temperature of up to 40 ° C. over a line length of, for example, 0.5 m, if the tap is not used for a long time . However, the carbonation of the beer is released and the quality is reduced.

Die Erfindung zielt darauf ab, eine Vorrichtung der einleitend angegebenen Gattung so auszubilden, daß bei hohem Hygienestandard ein im wesentlichen kontinuierlicher Zapfbetrieb gewährleistet ist. Die erfindungsgemäße Vorrichtung zeichnet sich dadurch aus, daß die Umschalteinrichtung in die Ausgangsleitungen der einzelnen Behälter eingeschaltete Kugelhähne mit Pneumatikantrieb aufweist, welche denselben Durchgangsquerschnitt haben wie die Ausgangsleitungen, wobei der Ausgang jedes Kugelhahnes unmittelbar mit der ebenfalls denselben Querschnitt wie die Ausgangsleitungen aufweisenden Zapfleitung in Verbindung steht, und daß jedem Kugelhahn ein Entlüftungsventil und jeder Ausgangsleitung im Anschluß an den zugehörigen Behälter eine außerhalb der Leitung angeordnete Fühleinrichtung zugeordnet ist, welche bei fehlender Flüssigkeitsströmung in der Ausgangsleitung ein Umschaltsignal an die Steuereinrichtung abgibt.The invention aims to design a device of the type specified in the introduction in such a way that an essentially continuous dispensing operation is ensured with a high standard of hygiene. The device according to the invention is characterized in that the switching device has ball valves with pneumatic actuation which are switched into the outlet lines of the individual containers and have the same passage cross section as the outlet lines, the outlet of each ball valve being directly connected to the tap line which also has the same cross section as the outlet lines , and that each ball valve is assigned a vent valve and each outlet line is connected to the associated container with a sensor arranged outside the line, which emits a switching signal to the control device in the absence of liquid flow in the outlet line.

Der wesentliche Vorteil der Erfindung besteht darin, daß der Bierfluß zwischen Vorratsbehälter und Zapfstelle durch keinerlei Zwischenbehälter unterbrochen und der Strömungsquerschnitt vom Behälter bis zur Zapfstelle konstant ist, d.h. keine Verengungen oder Erweiterungen aufweist, so daß die Ausgangsleitungen und die Zapfleitung auf einfache Weise periodisch mit Kugeln und Schwamm gereinigt werden können, die mittels Kohlensäure durch die Leitungen gepreßt werden. Dies gewährleistet einen Betrieb mit nur geringen Unterbrechungen, hohem Hygienestandard und gleichbleibender Bierqualität.The main advantage of the invention is that the beer flow between the storage container and the tap is not interrupted by any intermediate containers and the flow cross-section from the container to the tap is constant, i.e. has no constrictions or extensions, so that the outlet lines and the dispensing line can be cleaned periodically in a simple manner with balls and sponge, which are pressed through the lines by means of carbon dioxide. This ensures operation with only minor interruptions, high hygiene standards and consistent beer quality.

Es sei erwähnt, daß aus der DD-PS 21 135 eine Zapfvorrichtung für Bier bekannt ist, bei welcher die Ausgangsleitungen mehrerer Fässer über Zweiwegeventile mit einer gemeinsamen Zapfstelle in Verbindung stehen, wobei die Zapfleitung und die Ausgangsleitungen gleichen Querschnitt haben. Bei dieser Vorrichtung müssen jedoch die Zweiwegeventile mittels eines Seilzuges vom Schanktisch her umgestellt werden.It should be mentioned that a dispensing device for beer is known from DD-PS 21 135, in which the outlet lines of several kegs are connected to a common tap via two-way valves, the outlet line and the outlet lines having the same cross-section. In this device, however, the two-way valves must be moved from the bar table by means of a cable.

Aus der DE-A 28 38 181 ist ferner eine Getränkeabgabevorrichtung bekannt, bei welcher mehrere Fässer mit ihren Ausgangsleitungen an einen Zylinder mit motorbetätigtem Drehkolben angeschlossen sind, über welchen die Ausgangsleitungen nach Betätigung eines Wahlschalters mit einer Zapfleitung in Verbindung setzbar sind. Bei dieser Vorrichtung sind zwar ebenfalls gleiche Strömungsquerschnitte in den Ausgangsleitungen und in der Zapfleitung vorhanden, doch läßt sich die Vorrichtung nicht auf so einfache Weise reiningen wie die erfindungsgemäße und ist überdies in konstruktiver Hinsicht wesentlich aufwendiger.From DE-A 28 38 181 a beverage delivery device is also known, in which several drums are connected with their output lines to a cylinder with a motor-operated rotary piston, via which the output lines can be connected to a dispensing line after actuation of a selector switch. In this device, the same flow cross-sections are also present in the outlet lines and in the tap line, but the device cannot be cleaned in as easily as the one according to the invention and, moreover, is considerably more complex in terms of construction.

Gemäß der DE-A 20 34 443 ist schließlich ein Verfahren für die gasfreie Entleerung mehrerer Tanks, z.B. für Bier, bekannt, bei welchem zur Verhinderung eines Eintrittes von Gas in die Flüssigkeit bei der automatischen Umschaltung zwei Elektroden vorgesehen sind. Die eine Elektrode sitzt z.B. im Tankboden und schaltet ein neben dem Hauptventil in der Entleerungsleitung liegendes Drosselventil, wogegen eine End-Elektrode in einem Sumpfgefäß das Hauptventil schließt. In die Entleerungsleitung ist ein Entgasungsventil eingeschaltet. Die bekannte Ausführung hat den Nachteil, daß eine einwandfreie Reinigung wie im Falle der Erfindung wegen des Sumpfgefäßes und des Drossenventils nicht möglich ist. Bei keiner der vorstehend erörterten bekannten Vorrichtungen ist somit ein kontinuierlicher Zapfbetrieb bei gleichzeitiger einwandfreier Reinigungsmöglichkeit gewährleistet.According to DE-A 20 34 443, a method for the gas-free emptying of several tanks, e.g. for beer, known in which two electrodes are provided to prevent gas from entering the liquid during the automatic switchover. One electrode sits e.g. in the tank bottom and switches a throttle valve located next to the main valve in the drain line, whereas an end electrode in a sump vessel closes the main valve. A degassing valve is switched on in the drain line. The known design has the disadvantage that proper cleaning as in the case of the invention is not possible because of the sump vessel and the throttle valve. In none of the known devices discussed above, a continuous tap operation with simultaneous flawless cleaning is guaranteed.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung näher erläutert, die schematisch eine Vorrichtung gemäß der Erfindung zeigt.An embodiment of the invention is explained in more detail below with reference to the drawing, which schematically shows a device according to the invention.

Die dargestellte Vorrichtung ist zur Abgabe von Bier aus drei Vorratsbehältern 1, 2, 3 bestimmt, doch läßt sich die Erfindung auf eine beliebige Anzahl von Behältern anwenden. Die Behälter 1, 2, 3 stehen äber zugehörige Ausgangsleitungen 1', 2', 3' mit zugehörigen Absperreinrichtungen in Verbindung, die als Kugelhähne 4, 5, 6 ausgebildet sind. Jedem Kugelhahn ist ein pneumatisches Schalt- bzw. Betätigungsventil 7, 8, 9 zugeordnet, wobei diese Ventile über eine Leitung 17 an eine Druckluftquelle und über nicht dargestellte Signalleitungen an eine zentrale elektronische Steuereinrichtung 10 angeschlossen sind.The device shown is intended for dispensing beer from three storage containers 1, 2, 3, but the invention can be applied to any number of containers. The containers 1, 2, 3 are connected via associated outlet lines 1 ', 2', 3 'to associated shut-off devices which are designed as ball valves 4, 5, 6. A pneumatic switching or actuation valve 7, 8, 9 is assigned to each ball valve, these valves being connected via a line 17 to a compressed air source and via signal lines (not shown) to a central electronic control device 10.

In zu den einzelnen Vorratsbehältern 1, 2, 3 führenden Zuleitungen 11, 12, 13 für Treibgas (C02) sind Gasventile 14, 15, 16 eingeschaltet, die über eine zentrale Gasleitung 17' an eine nicht gezeigte Druckgasquelle angeschlossen sind. Die Gasventile 14, 15, 16 sind ferner über nicht gezeigte elektrische Signalleitungen ebenfalls an die zentrale Steuereinrichtung 10 angeschlossen. Die Kugelhähne sowie Ventile sind gemeinsam mit der Steuereinrichtung in einem Gehäuse G untergebracht.In the supply lines 11, 12, 13 for propellant gas (C0 2 ) leading to the individual storage containers 1, 2, 3, gas valves 14, 15, 16 are switched on, which are connected via a central gas line 17 'to a compressed gas source, not shown. The gas valves 14, 15, 16 are also electri not shown cal signal lines are also connected to the central control device 10. The ball valves and valves are housed together with the control device in a housing G.

Die Kugelhähne 4, 5, 6 und die aus diesen austretenden Zapfleitungen 1", 2", 3" haben denselben Durchgangsquerschnitt wie die Ausgangsleitungen 1', 2', 3'. Die Zapfleitungen münden in einen zentralen Leitungsabschnitt 18, der ebenfalls denselben Querschnitt hat und gegebenenfalls über eine nicht gezeigte Pumpe zu einer Zapfstelle Z führt. Den Ausgangsleitungen 1', 2', 3' sind im Anschluß an die zugehörigen Behälter Fühleinrichtungen 19, 20, 21 für das Vorhandensein der Flüssigkeitsströmung zugeordnet, die außerhalb der jeweiligen Leitung angeordnet und über elektrische Signalleitungen 22, 23, 24 mit der Steuereinrichtung 10 verbunden sind. Jeder Kugelhahn 4, 5, 6 ist ferner mit einem handbetätigbaren Entlüftungsventil 4', 5', 6' für die zugehörige Ausgangsleitung ausgestattet.The ball valves 4, 5, 6 and the tap lines 1 ", 2", 3 "emerging from them have the same passage cross section as the outlet lines 1 ', 2', 3 '. The tap lines open into a central line section 18, which also has the same cross section and if necessary leads via a pump, not shown, to a tap Z. The outlet lines 1 ', 2', 3 'are assigned to the associated containers, sensing devices 19, 20, 21 for the presence of the liquid flow, which are arranged outside the respective line and are connected to the control device 10 via electrical signal lines 22, 23, 24. Each ball valve 4, 5, 6 is further equipped with a manually operable vent valve 4 ', 5', 6 'for the associated output line.

Die dargestellte Vorrichtung arbeitet wie folgt: Nach Einschalten der vorprogrammierten Steuereinrichtung 10 wird von dieser ein Einschaltsignal an das Schaltventil 7 des Pneumatikantriebs des ersten Kugelhahnes 4 abgegeben und dieser dadurch geöffnet. Zugleich mit dem Kugelhahn 4 wird über die Steuereinrichtung 10 das zugeordnete erste Gasventil 14 geöffnet, so daß das Treibgas in den Behälter 1 gelangt und das Bier über die Ausgangsleitung 1' und den Kugelhahn 4 sowie die Zapfleitung 18 zur Zapfstelle treibt. Sobald das Leerwerden des ersten Behälters 1 über die der Ausgangsleitung 1' zugeordnete, den Durchfluß in der Leitung abtastende Fühleinrichtung 19 an die Steuereinrichtung 10 gemeldet wird, werden von dieser der erste Kugelhahn 4 sowie das zugehörige Gasventil 14 geschlossen und der zweite Kugelhahn 5 über das Schaltventil 8 sowie das zweite Gasventil 15 geöffnet, was zur Folge hat, daß das Bier nun über die zweite Ausgangsleitung 2' abgegeben wird. Dieser Zyklus wiederholt sich bis zum letzten Behälter.The device shown works as follows: after switching on the preprogrammed control device 10, a switch-on signal is emitted by it to the switching valve 7 of the pneumatic drive of the first ball valve 4 and the latter is opened thereby. At the same time as the ball valve 4, the associated first gas valve 14 is opened via the control device 10, so that the propellant gas enters the container 1 and drives the beer via the outlet line 1 'and the ball valve 4 and the dispensing line 18 to the tap. As soon as the emptying of the first container 1 is reported to the control device 10 via the sensing device 19 assigned to the outlet line 1 ', which senses the flow in the line, the first ball valve 4 and the associated gas valve 14 are closed and the second ball valve 5 via the Switching valve 8 and the second gas valve 15 are opened, which means that the beer is now dispensed via the second outlet line 2 '. This cycle is repeated until the last container.

In der Steuereinrichtung ist eine nicht dargestellte Warnanzeige vorhanden, die optisch oder akustisch anzeigt, daß nur mehr ein Behälter vorrätig bzw. der letzte Behälter angezapft worden ist. Es werden sodann die bereits geleerten Behälter gegen volle ausgetauscht und es werden die Ausgangsleitungen 1', 2' usw. über das am zugehörigen Kugelhahn vorgesehene Entlüftungsventil entlüftet, so daß sie sich unter der Wirkung des Behälterinnendruckes mit Flüssigkeit füllen können, bevor die Steuereinrichtung nach Leerwerden des letzten Behälters wieder auf den ersten Behälter umschaltet und die Bierabgabe in der schon erläuterten Weise durch Öffnen des ersten Kugelhahnes und des zugeordneten Treibgasventiles erneut beginnt.In the control device there is a warning display, not shown, which optically or acoustically indicates that only one container is left in stock or the last container has been tapped. The already emptied containers are then exchanged for full ones and the outlet lines 1 ', 2' etc. are vented via the vent valve provided on the associated ball valve, so that they can fill with liquid under the effect of the internal pressure of the container before the control device empties of the last container switches back to the first container and the beer dispensing begins again in the manner already explained by opening the first ball valve and the associated propellant gas valve.

Die Länge jeder Ausgangsleitung 1', 2' usw. und die Schließgeschwindigkeit des Kugelhahnes sind so gewählt, daß sich die Ausgangsleitung beim Leerwerden des Behälters nur über einen Teil ihrer Länge mit Treibgas füllen kann. Die periodische Reinigung der vom Bier beaufschlagten Leitungen erfolgt in üblicher Weise mittels Kugeln und Schwamm, die mittels Kohlensäure durch die Leitungen gedrückt werden.The length of each outlet line 1 ', 2' etc. and the closing speed of the ball valve are selected so that when the container is emptied the outlet line can only be filled with propellant gas over part of its length. Periodic cleaning of the lines acted upon by the beer is carried out in the usual way by means of balls and sponge, which are pressed through the lines by means of carbon dioxide.

Das dargestellte und beschriebene Ausführungsbeispiel kann im Rahmen des allgemeinen Erfindungsgedankens verschiedentlich abgewandelt werden. So können beispielsweise die von Hand betätigbaren Entlüftungsventile 4', 5', 6' auch als automatisch betätigbare Ventile ausgebildet sein. Ferner können die Schaltventile für die Kugelhähne auch mit Hilfe des Treibgases für das Bier betätigt werden.The illustrated and described embodiment can be modified in various ways within the scope of the general inventive concept. For example, the manually operated vent valves 4 ', 5', 6 'can also be designed as automatically actuated valves. Furthermore, the switching valves for the ball valves can also be operated using the propellant gas for the beer.
