Description
Die Erfindung betrifft einen Rotationsfüller zum Abfüllen von Flüssigkeiten, insbesondere Getränken, in Gefäße, insbesondere Flaschen, unter hochreinen Abfüllbedingungen, mit einer Vielzahl von am Umfang eines Rotors verteilt angeordneten Füllventilen mit Halteelementen zum Halten der Gefäße unter den Füllventilen während des Umlaufs und mit einem im Bereich der Flaschenumlaufbahn mit einer Innenwand, einer Außenwand, einer Deckenwand und einer Bodenwand abgegrenzten Reinstraum, in dem durch Einleiten von hochreinem Gas, z.B. steriler Luft, eine hochreine Atmosphäre während des Abfüllvorgangs aufrechterhalten wird.The invention relates to a rotary filler for filling of liquids, especially beverages, in vessels, especially bottles, under high purity filling conditions, with a variety of distributed around the circumference of a rotor arranged filling valves with holding elements for holding the Vessels under the filling valves during circulation and with one in the area of the bottle orbit with an inner wall, an outer wall, a ceiling wall and a bottom wall delimited clean room in which by introducing high purity gas, e.g. sterile air, a high purity Atmosphere is maintained during the filling process.
Für bestimmte Getränke ist es erforderlich, den Abfüllvorgang unter hochreinen Bedingungen durchzuführen, um zu verhindern, daß die Getränke mit die Haltbarkeit und die Qualität des Getränkes beeinträchtigenden Schädlingen, z.B. Schimmelpilzen, in Berührung kommen. Betroffen hiervon sind insbesondere solche Getränke, die alkohol- und CO2-frei sind und einen PH-Wert von weniger als 4,5 haben. Da solche Getränke z.B. insbesondere auch dem Verderben durch Schimmelpilze unterliegen und Schimmelpilze hauptsächlich als Luftkontaminanten auftreten, sind an solchen Abfüllanlagen, die zum Abfüllen derartiger Getränke geeignet sind, zusätzliche lüftungstechnische Maßnahmen erforderlich.For certain beverages, it is necessary to carry out the filling process under high-purity conditions in order to prevent the beverages from coming into contact with pests, for example mold, which impair the shelf life and the quality of the beverage. This affects in particular those beverages that are free of alcohol and CO 2 and have a pH value of less than 4.5. Since such beverages are particularly subject to spoilage due to mold and molds mainly occur as air contaminants, additional ventilation measures are required on such filling systems that are suitable for filling such beverages.
Ein Füller, der für diese Art von Abfüllung gedacht ist, ist in der europäischen Anmeldung 405 402 beschrieben. Diese Füllmaschine ist als Rotationsfüller ausgestaltet. Sie weist am Umfang verteilt angeordnete Füllventile auf. Flaschen werden unter den Füllventilen mit Halteelementen gehalten, die in einem abgegrenzten, einen Reinstraum bildenden Bereich am Füller umlaufen. Der Reinstraum wird durch entsprechende Wände, nämlich eine Innenwand, eine Außenwand, eine Deckenwand und eine Bodenwand begrenzt. Die Deckenwand wird von einer oberen Füllerplatte und die Bodenwand von einer unteren Füllerplatte gebildet. Zwischen den beiden Platten verläuft die Innenwand. Die stationäre Außenwand dagegen bildet zur Deckenwand und zur Bodenwand hin Schlitze, durch die die in den so begrenzten Raum eingeblasene Sterilluft entweichen kann. Die Sterilluft wird von der Deckenplatte her um das Füllventil herum in den Reinstraum eingeleitet. Die Flaschen stehen in dem Reinstraum auf der Bodenplatte und werden seitlich mit Halteelementen gehalten, die jedoch keine Höhenbewegung der Flaschen zulassen. Da das Füllorgan durch die Deckenwand hindurch geführt ist und über eine Leitung mit dem oberhalb des Füllers angeordneten Vorratsbehälter in Verbindung steht und das eigentliche Füllventil außerhalb des Reinstraumes angeordnet ist, besteht die Gefahr, daß über die Länge der Verbindungsleitung und die daran angeschlossenen Elemente, wie Füllventil und Durchflußmesser, Keime beim Abfüllvorgang in den Reinstraum eingetragen werden.A filler that is intended for this type of filling is in European application 405 402. This Filling machine is designed as a rotary filler. She points Filling valves distributed around the circumference. bottles are held under the filling valves with holding elements, those in a delimited, clean room Run around the area of the filler. The clean room is through corresponding walls, namely an inner wall, an outer wall, bounded a ceiling wall and a bottom wall. The ceiling wall is from an upper filler plate and the bottom wall from a lower filler plate. Between the two Panels runs the inner wall. The stationary outer wall on the other hand forms towards the ceiling wall and the floor wall Slots through which in the so limited space injected sterile air can escape. The sterile air is from the ceiling plate around the filling valve into the Clean room initiated. The bottles are in that Clean room on the base plate and be on the side Holding elements held, but no vertical movement of the Allow bottles. Because the filler through the ceiling wall is passed through and via a line with the above the filler arranged in communication and the actual filling valve outside the clean room is arranged, there is a risk that over the length of the Connecting line and the elements connected to it, like filling valve and flow meter, germs during the filling process be entered in the clean room.
Ausgehend von diesem Stand der Technik liegt der Erfindung das Problem zugrunde, einen Rotationsfüller anzugeben, mit dem hochreine Abfüllbedingungen aufrechterhalten werden können, wobei gleichzeitig die Konstruktion möglichst einfach sein soll.The invention is based on this prior art the problem of specifying a rotary filler with which maintain high-purity bottling conditions can, at the same time the construction if possible should be easy.
Gelöst wird diese Aufgabe bei einem Rotationsfüller der eingangs genannten Art dadurch, daß die den Reinstraum nach oben hin begrenzende Deckenwand zumindest teilweise von der Unterseite eines die abzufüllende Flüssigkeit speichernden Ringkessels und der unmittelbar darunter angeordneten Füllventile gebildet wird.This task is solved by a rotary filler type mentioned in that the clean room after ceiling wall delimiting at the top at least partially from the Bottom of a liquid storing the liquid to be filled Ring bowl and the one immediately below Filling valves is formed.
Dadurch, daß die den Reinstraum nach oben hin begrenzende Deckenwand zumindest teilweise von der Unterseite eines die abzufüllende Flüssigkeit speichernden Ringkessels und den unmittelbar darunter angeordneten Füllventilen gebildet wird, liegen die Füllventile selbst im Reinstraum und es ist ein direkter Zulauf vom Ringkessel zu den Füllventilen möglich, so daß die abzufüllende Flüssigkeit auf kürzestem Weg ohne die Gefahr einer Kontamination von Keimen abgefüllt werden kann. Dadurch, daß die Unterseite des Ringkessels zum Teil selbst die obere Deckenwand bildet, ergibt sich außerdem eine konstruktive Vereinfachung. Insgesamt schafft die Kombination dieser Merkmale somit die Möglichkeit, bei einfacher Konstruktion einen hochreinen Abfüllvorgang zu gewährleisten. In that the upper limit of the clean room Ceiling wall at least partially from the bottom of a ring tank and the liquid to be filled filling valves arranged immediately below the filling valves themselves are in the clean room and it is a direct feed from the ring bowl to the filling valves possible so that the liquid to be filled on the shortest Bottled away without the risk of contamination of germs can be. The fact that the bottom of the ring bowl to Part of it forms the upper ceiling wall also a constructive simplification. Overall creates the combination of these features thus the possibility of simple construction to a high-purity filling process guarantee.
In vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, daß ein Teil der Deckenwand von einer den Ringkessel tragenden Platte gebildet wird. Durch diesen Teil werden dann bevorzugt Antriebsstangen als Teil der Antriebselemente für die Halteelemente hindurchgeführt. In diesem Zusammenhang ist es auch vorteilhaft, wenn diese Antriebsstangen durch in ihrer Länge wenigstens der Hubhöhe der Halteelemente entsprechende Hülsen geführt sind. Die Hülse, die die Antriebsstange umgibt, schafft dort einen Raum, in dem Sterilluftatmosphäre vorherrscht. Wenn die Länge der Hülse wenigstens der Hubhöhe entspricht, bedeutet dies, daß der Teil der Antriebsstange, der in angehobenem Zustand außerhalb der Hülse liegt, beim Absenken immer noch im Bereich der Hülse verbleibt, so daß darüber von der Außenatmosphäre keine Keime in das Innere des Reinstraumes auch bei abgesenkten Halteelementen eingetragen werden.In an advantageous embodiment of the invention, that part of the ceiling wall of one of the ring kettles supporting plate is formed. Be through this part then drive rods are preferred as part of the drive elements passed through for the holding elements. In this Context, it is also beneficial if this Drive rods by at least the length of the lifting height corresponding holding sleeves are guided. The Sleeve that surrounds the drive rod creates one there Space in which the sterile air atmosphere prevails. If the Length of the sleeve corresponds at least to the lifting height this is that part of the drive rod that is raised in Condition outside of the sleeve is still when lowering remains in the area of the sleeve, so that from the Outside atmosphere no germs in the interior of the clean room can also be entered with the holding elements lowered.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die Außenwand und vorzugsweise auch die Bodenwand derart an einem Traggestell angeordnet sind, daß sie im Bedarfsfall einen Zugang zum Reinstraum ermöglichen. Der Zugang kann beispielsweise dadurch ermöglicht werden, daß die Außenwand und/oder die Bodenwand in einzelne Segmente unterteilt ist, die jeweils über Scharniere an dem Traggestell angeordnet sind, so daß dann, wenn ein Zugang zum Reinstrauminneren erforderlich ist, an der entsprechenden Stelle die Außenwand geöffnet werden kann. Dasselbe läßt sich natürlich auch erreichen, wenn die Außenwand insgesamt vom Traggestell abnehmbar angeordnet wird. Bodenwand und Außenwand drehen also nicht mit dem Füller mit, sondern werden vom Traggestell gehalten und erlauben im Bedarfsfall einen Zugang. Dagegen dreht die teilweise von der Unterseite des Ringkessels gebildete Deckenwand und die Innenwand mit dem Rotor des Rotationsfüllers mit.In a further embodiment of the invention it is provided that the outer wall and preferably also the bottom wall a support frame are arranged so that if necessary allow access to the clean room. Access can be made possible, for example, by the outer wall and / or the bottom wall is divided into individual segments, which are each arranged on hinges on the support frame are so that when there is access to the clean interior the outer wall is required at the appropriate point can be opened. The same can of course be done reach when the outer wall total of the support frame is arranged detachably. Turn the bottom wall and outer wall not with the fountain pen, but from the Supported frame and allow one if necessary Access. On the other hand, the part turns from the bottom of the Ring kettle formed ceiling wall and the inner wall with the Rotary filler rotor with.
Um die in den Reinstraum eingeleitete Sterilluft in ständigem Strom zu halten, sind Luftaustrittsschlitze vorgesehen, vorzugsweise zwischen der Bodenwand und der Innenwand, sowie zwischen der Außenwand und der Deckenwand. Es wird also in den Reinraum ständig Sterilluft mit Überdruck (darunter wird jedes Gas verstanden, das den gewünschten Reinheitsanforderungen entspricht) eingespeist und dieses entweicht durch die Schlitze wieder, so daß ein ständiges Durchspülen mit Gas stattfindet, was die Aufrechterhaltung hochreiner Abfüllbedingungen weiter fördert.To the sterile air introduced into the clean room in Keeping electricity steady are air vents provided, preferably between the bottom wall and the Inner wall, as well as between the outer wall and the ceiling wall. So there is always sterile air in the clean room Overpressure (this is understood to mean any gas that corresponds to the desired purity requirements) and this escapes through the slots again, so that a constant purging with gas takes place what the Maintenance of high-purity bottling conditions continues promotes.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß der Sterilgaseintritt in den Reinstraum durch seitlich im Bereich der Außenwand vorgesehenen Gaseintrittsöffnungen erfolgt. Diese Gaseintrittsöffnungen können an der Seitenwand verteilt an mehreren Stellen vorgesehen sein, so daß ein gleichmäßiger Gaseintritt möglich ist.In a further embodiment of the invention it is provided that the sterile gas entry into the clean room through the side in Area of the outer wall provided gas inlet openings he follows. These gas inlet openings can at the Side wall can be provided in several places, so that even gas entry is possible.
Wenn die Bodenwand zum Luftaustrittsschlitz hin nach unten geneigt verläuft, wird sichergestellt, daß evtl. sich einstellende Flüssigkeitsspritzer oder im Falle einer nicht erkannten undichten Flasche ablaufende Flüssigkeit, die auf die Bodenwand fällt, von selbst in Richtung zum Luftaustrittsschlitz hin abläuft bzw. durch den zum Luftaustrittsschlitz gerichteten Gasstrom mitgenommen wird, so daß keine dauernden Flüssigkeitsablagerungen im Bereich der Bodenwand zu befürchten sind. When the bottom wall goes down towards the air outlet slot runs inclined, it is ensured that possibly adjusting liquid splashes or in the case of a not Detected leaking bottle draining liquid that is on the bottom wall falls, by itself towards the Air outlet slot runs out or through the to Air outlet slot directed gas flow is taken so that no permanent fluid deposits in the area the bottom wall are to be feared.

Die Figur 1 zeigt in einer schematischen Draufsicht den
grundsätzlichen Aufbau des erfindungsgemäßen
Rotationsfüllers 1. Der Rotationsfüller 1 umfaßt einen Rotor
2, an dem am Umfang gleichmäßig verteilt eine Vielzahl von
Füllventilen 3 angeordnet sind. Die Füllventile laufen auf
der Umlaufbahn 4 bei Antrieb des Rotors 2 um die Achse 11
um. Während des Umlaufs werden Flaschen 18, die unter den
Füllventilen 3 gehalten werden (vgl. Figur 2), gefüllt.1 shows a schematic plan view of the
basic structure of the invention
Die Flaschen 18 werden über ein Zuförderband 5 und einen
Einlaufstern 6 an den Rotor 2 in bekannter Weise übergeben.
Nach dem Umlauf werden die Flaschen 18 vom Transferstern 7
an einen Verschließer 8 übergeben. Nach dem Verschließen
werden die Flaschen 18 von einem Auslaufstern 9 übernommen
und auf ein Abförderband 10 verbracht, von wo sie zur
weiteren Behandlung an die nächste Station übergeben werden.The
Um die Flaschen 18 unter hochreinen Bedingungen abfüllen zu
können, ist im Bereich der Umlaufbahn am Rotor 2 ein durch
die Außenwand 12 umrissener Reinstraum erzeugt, in dem nicht
nur die Füllventile 3 liegen, sondern auch der Einlaufstern
6, der Transferstern 7, der Verschließer 8 sowie dessen
Auslaufstern 9.To fill the
Über seitlich am Umfang im Bereich der Außenwand 12
angebrachte Gaseintrittsöffnungen 34 erfolgt die
Sterilluftzufuhr (Zufuhr von sterilem Gas), so daß innerhalb
des durch die Außenwand 12 umgrenzten Raumes eine hochreine
Atmosphäre während des Abfüllvorganges aufrechterhalten
werden kann.Via laterally on the circumference in the area of the
Aus der Schnittansicht der Figur 2 im Bereich der Linie II-II
der Figur 1 ist der Aufbau deutlicher zu erkennen. Auf
einer Rotorplatte 17, die Teil des Rotors 2 bildet und mit
umläuft, ist ein Ringkessel 16 angeordnet, in den durch eine
Flüssigkeitszulaufleitung 35 die abzufüllende Flüssigkeit 36
eingeleitet wird.From the sectional view of Figure 2 in the area of line II-II
1 shows the structure more clearly. On
a
Unmittelbar am unteren Ausgang des Ringkessels 16 sitzen die
Füllventile 3. Die Unterseite 15 des Ringkessels 16, die
Unterseite des Füllventils 3 sowie die Unterseite der Platte
17 bilden eine obere Deckenwand des darunterliegenden
Reinstraumes 19, der seitlich durch die an der Platte 17
befestigte zylindrische Innenwand 13 zur Rotorachse 11 hin
und radial nach außen durch die stationäre, teilzylindrische
Außenwand 12 begrenzt ist. Nach unten ist dieser Raum durch
die mit Neigung verlaufende stationäre Bodenwand 14
abgeschlossen. Die Wände 12 und 14 laufen im wesentlichen um
den gesamten Umfang des Rotors 2 herum, allerdings mit
entsprechenden Zulauf- und Auslauföffnungen im Bereich des
Flaschenein- und -auslaufes (vgl. Figur 1). Immediately at the lower exit of the
Die Außenwand 12 und die Bodenwand 14 wird über ein
Traggestell 28 gestützt, das am Umfang verteilte Stützen 30
aufweist, sowie davon abzweigende Arme 29, die nach innen
zur Rotorachse hin verlaufen und die untere Tragplatte 31
des Rotors 2 über einen Kugeldrehkranz drehbar abstützen, an
der die die obere Platte 17 tragende Innenwand 13 befestigt
ist. Die Außenwand 12 kann über den Umfang verteilt in
einzelne Segmente unterteilt sein, die jeweils für sich z.B.
über Scharniere geöffnet werden können, so daß ein Zugang in
den Reinstraum möglich ist. Vorzugsweise ist auch die
Bodenwand 14 entsprechend abnehmbar oder wegschwenkbar.The
Die Flaschen 18, im dargestellten Ausführungsbeispiel PET-Kunststoffflaschen,
werden von Halteelementen 27 an die
Auslaufmündung des Füllventils 3 gedrückt. Jedes
Halteelement 27 wird über Antriebselemente 21 auf- und
abgefahren. Es nimmt also am Flascheneinlauf eine Flasche 18
von einer unteren Stellung auf und verbringt sie in die in
Figur 2 dargestellte Position unmittelbar an das Auslaufende
des Füllventils 3. Nach dem Füllvorgang wird über die
Antriebselemente 21 die Flasche 18 wieder abgesenkt. Die
Antriebselemente 21 umfassen Antriebsstangen 20, das
Gestänge 24, die Gasfeder 25, die Abtastrolle 23 sowie die
Steuerkurve 22. Die Steuerkurve 22 ist feststehend innerhalb
der drehenden Teile des Rotors 2 angeordnet und bewirkt über
die Abtastrolle 23 in Verbindung mit der nach oben hin
wirkenden Gasfeder 25 ein Heben und Senken des Gestänges 24,
so daß darüber auch die Antriebsstangen 20 und die
Haltelemente 27 von der Innenseite der Wand 13 bzw. des
Rotors 2 her gesteuert werden. Im Bereich der Rotorplatte 17
sind Durchführungen in Form von Hülsen 26 geschaffen, durch
die die Antriebsstangen 20 hindurchtreten. Die Länge 1
dieser Hülsen 26 ist so bemessen, daß sie mindestens der
Hubhöhe des Gestänges 21 entspricht, so daß der in der
gezeigten Position außerhalb der Hülse 26 liegende obere
Teil der Antriebsstangen 20 nach dem Absenken noch innerhalb
der Hülse 26 verbleibt und dadurch auch nicht solche Keime
in das Innere des Reinstraumes 19 beim Absenken eingetragen
werden, die sich evtl. an dem nicht im Reinstraum liegenden
oberen Teil der Antriebsstangen 20 abgesetzt haben.The
Der eigentliche Füllvorgang läuft in an sich bekannter Weise
ab. Hierzu werden die einzelnen Füllventile 3 und
zusätzliche Steuerventile 37 in geeigneter Weise
beaufschlagt, um Spülgas einzuleiten, den Rückgasaustritt zu
steuern, das Flüssigkeitsventil zu öffnen und dergl. mehr.The actual filling process runs in a manner known per se
from. For this purpose, the
Wie bereits geschildert, wird über die seitlich an der
Außenwand 12 angeordneten Sterilluftzufuhröffnungen 34
ständig Sterilluft in den Reinstraum 19 eingeblasen. Diese
Sterilluft kann durch einen Luftaustrittsschlitz 32 zwischen
Bodenwand 14 und Innenwand 13 einerseits und durch einen
Luftaustrittsschlitz 33 zwischen Außenwand 12 und der
Unterseite 15 des Ringkessels 16 andererseits austreten, so
daß der Reinstraum 19 ständig durchspült wird. Auch durch
den Zwischenraum zwischen Antriebsstange 20 und Hülse 26,
also durch das Innere der Hülse 26 kann etwas Sterilgas
entweichen, so daß die Hülse 26 zur Außenseite hin ebenfalls
ständig durchspült wird.As already described, is on the side of the
Sterile
Da die Flasche 18 unmittelbar an dem am Ringkessel 16
angeordneten Füllventil 3 mit Halteelementen 27 gehalten
wird und die Wege der Flüssigkeit in die Flasche 18 sehr
kurz sind, wird im Bereich des eigentlichen Abfüllvorganges
eine hochreine Atmosphäre ohne Gefahr des Keimeintrages
aufrechterhalten. Die Auslauföffnung des Füllventils 3 wird
ständig von der Sterilluft umströmt, ebenso der
Flaschenhals, so daß ein Abfüllvorgang unter hochreinen
