Die in der Figur 1 allgemein mit 1 bezeichnete Verschließmaschine dient zum Verschließen von Flaschen 2 mit Verschlüssen 3 in Form von aufschraubbaren Verschlüssen oder Kappen. Die Verschließmaschine 1 besteht hierfür aus einem um eine vertikale Maschinenachse MA umlaufend antreibbaren Rotor 4, an dessen Umfang ein die Maschinenachse MA konzentrisch umschließender ringkanalartiger Sterilraum 5 vorgesehen ist, der innerhalb einer Einhausung gebildet und durch mehrere Wandungen zur Umgebung, d.h. zu dem von der Umgebung gebildeten Unsterilraum hin begrenzt ist, und zwar bei der schematischen Darstellung der Figur 1 durch eine obere Wandung 6, durch eine bezogen auf die Maschinenachse MA radial innen liegende und die Maschinenachse MA ringförmig umschließende Wandung 7, durch eine bezogen auf die Maschinenachse MA radial außen liegende und die Maschinenachse MA konzentrisch umschließende Wandung 8 sowie an der Unterseite durch Abschnitte 7.1 bzw. 8.1 der Wandungen 7 und 8. Die Wandungen 6 und 7 einschließlich des Abschnittes 7.1 sind am Rotor 4 mit diesem umlaufend vorgesehen. Die Wandung 8 einschließlich des Abschnitts 8.1 ist mit dem Rotor nicht umlaufend an einem Maschinengestell der Verschließmaschine 1 vorgesehen. An den Übergängen zwischen den Wandungen 6 und 8 sowie den Abschnitten 7.1 und 8.1 ist jeweils eine Dichtung 9 bzw. 10, beispielsweise eine hydraulische Dichtung oder Siphondichtung vorgesehen, so dass der Sterilraum 5 durch die Wandungen 6 - 8 und die zugehörigen Dichtungen 9 und 10 dicht von der Umgebung bzw. dem Unsterilraum getrennt ist.The in the FIG. 1 A capping machine generally designated 1 serves to close bottles 2 with closures 3 in the form of screw-on closures or caps. For this purpose, the closing machine 1 consists of a rotor 4 that can be driven circumferentially around a vertical machine axis MA, on the circumference of which an annular axis-like sterile space 5 surrounding the machine axis MA is provided, which is formed within an enclosure and through several walls to the environment, ie to the environment limited in the unsterile space, and in the schematic representation of FIG. 1 by an upper wall 6, by a relative to the machine axis MA radially inwardly and the machine axis MA annularly enclosing wall 7, by a relative to the machine axis MA radially outer and the machine axis MA concentrically enclosing wall 8 and at the bottom by sections 7.1 or 8.1 of the walls 7 and 8. The walls 6 and 7 including the section 7.1 are provided on the rotor 4 with this circumferentially. The wall 8 including the section 8.1 is not circumferentially provided with the rotor on a machine frame of the closing machine 1. At the transitions between the walls 6 and 8 and the sections 7.1 and 8.1 each have a seal 9 and 10, for example, a hydraulic seal or siphon seal provided, so that the sterile room 5 through the walls 6-8 and the associated seals 9 and 10 is tightly isolated from the environment or the non-sterile space.

Zum Verschließen der Flaschen 2 mit den Verschlüssen 3 sind am Umfang des Rotors 4 mehrere Verschließstationen 11 gebildet, von denen in der Figur 1 lediglich zwei dargestellt und die in gleichmäßigen Winkelabständen um die Maschinenachse MA verteilt vorgesehen sind. Jede Verschließstation 11 besteht aus einem Verschließwerkzeug 12, mit dem der jeweilige Verschluss 3 auf die mit ihrer Flaschenmündung unterhalb des Verschließwerkzeugs 12 an einem Behälterträger 13 gehaltene und vollständig im Sterilraum 5 aufgenommene Flasche 2 aufgeschraubt wird. Bei der dargestellten Ausführungsform sind die Flaschen 2 an dem jeweiligen Behälterträger 13, der durch eine nicht dargestellte Steuerkurve höhengesteuert ist, hängend gehalten, und zwar an einem unterhalb der Flaschenmündung ausgebildeten Behälterflansch.For closing the bottles 2 with the closures 3, several closing stations 11 are formed on the circumference of the rotor 4, of which in the FIG. 1 only two shown and distributed at equal angular intervals around the machine axis MA are provided. Each closing station 11 consists of a closing tool 12 with which the respective closure 3 is screwed onto the bottle 2 held with its bottle mouth below the closing tool 12 on a container carrier 13 and completely accommodated in the sterile room 5. In the illustrated embodiment, the bottles 2 on the respective container carrier 13, which is height-controlled by a control cam, not shown, suspended, on a container flange formed below the bottle mouth.

Das jeweilige Verschließwerkzeug 12 ist als Schraubverschließer ausgebildet und besteht u.a. aus einem z.B. elektromotorischen Antrieb 14, aus einer mit ihrer Achse parallel zur Maschinenachse MA orientierten Spindel 15, die mit ihrem oberen Ende antriebsmäßig mit dem Antrieb 14 bzw. der Motorwelle dieses Antriebs verbunden ist, sowie aus einem am unteren Ende axial gefederten Verschließerkopf 16, mit dem bei umlaufendem Rotor 4 der jeweilige Verschluss 3 an einer nicht dargestellten Verschlussübergabeposition abgenommen, dann durch Anheben der jeweiligen Flasche 2 gegen den Verschließerkopf 16 auf die Flaschenmündung aufgesetzt und anschließend über den von dem Antrieb 14 über die Spindel 15 angetriebenen Verschließerkopf 16 auf die betreffende Flasche 2 aufgeschraubt wird, wie dies dem Fachmann an sich bekannt ist.The respective closing tool 12 is designed as a screw capper and is u.a. from a e.g. electromotive drive 14, from a with its axis parallel to the machine axis MA oriented spindle 15 which is drivingly connected at its upper end to the drive 14 and the motor shaft of this drive, as well as from an axially sprung at the lower end capper head 16, with the at circulating rotor 4, the respective closure 3 is removed at a closure transfer position, not shown, then placed by lifting the respective bottle 2 against the capper head 16 on the bottle mouth and then screwed over the driven by the drive 14 via the spindle 15 capper head 16 on the relevant bottle 2 as is known per se to those skilled in the art.

Wie in den Figuren 1 und 2 dargestellt, befindet sich der Antrieb 14 sowie ein sich an diesen Antrieb axial anschließendes und eine obere Teillänge der Spindel 15 aufnehmendes rohrartiges Gehäuse 17, in dem die Spindel 15 bei der dargestellten Ausführungsform zweifach gelagert ist (oberes Lager 18 und unteres Lager 19), außerhalb des Sterilraumes 5 und oberhalb der Wandung 6. Ein besonderes Problem besteht dabei in dem dichten Durchführen der Spindel 15 durch die Wandung 6. Hierfür ist für jede Verschließstation 11 an der Oberseite der Wandung 6 eine in den Figuren allgemein mit 20 bezeichnete hydraulische Dichtung oder Siphondichtung vorgesehen. Diese besteht u.a. aus einem als Formkörper ausgebildeten Dichtungselement 21 aus einem geeigneten Material, beispielsweise aus Metall. Wie insbesondere in der Figur 4 deutlich dargestellt ist, umfasst das Dichtungselement 21 einen an der Oberseite offenen napfartigen Abschnitt 22, der zwei konzentrisch zueinander angeordnete und bei der dargestellten Ausführungsform kreiszylinderförmige Wandabschnitte 22.1 und 22.2 aufweist, die zwischen sich einen Ringkanal 23 bilden, der der Dichtungsraum der Siphondichtung 20 ist und an der Unterseite des Abschnitts 22 bzw. des Formkörpers 21 geschlossen und an der Oberseite des Abschnitts 22 bzw. des Formkörpers 21 offen ist. Der innere Wandabschnitt 22.1 umschließt eine Öffnung 24, durch die die Spindel 15 durch das Dichtungselement 21 bzw. die Siphondichtung 20 hindurchgeführt ist. Weiterhin besitzt der innere Wandabschnitt 22.1 eine im Vergleich zum äußeren Wandabschnitt 22.2 reduzierte Höhe.As in the FIGS. 1 and 2 shown, the drive 14 and an axially adjoining this drive and an upper part length of the spindle 15 receiving tubular housing 17, in which the spindle 15 is mounted in the illustrated embodiment in duplicate (upper bearing 18 and lower bearing 19), outside A special problem is the tight passage of the spindle 15 through the wall 6. For this purpose, for each closing station 11 at the top of the wall 6 in the figures generally designated 20 hydraulic seal or siphon seal intended. This consists inter alia of a formed as a molded body sealing member 21 made of a suitable material, for example of metal. As in particular in the FIG. 4 is clearly shown, the sealing member 21 comprises an open at the top cup-like portion 22, which has two concentric with each other and in the illustrated embodiment circular cylindrical wall sections 22.1 and 22.2, which form between them an annular channel 23, which is the sealing space of the siphon 20 and closed at the bottom of the portion 22 and the molding 21 and at the top of the portion 22 and the molding 21 is open. The inner wall section 22.1 encloses an opening 24, through which the spindle 15 is guided through the sealing element 21 or the siphon seal 20. Furthermore, the inner wall section 22.1 has a reduced height compared to the outer wall section 22.2.

Das Dichtungselement 21 ist weiterhin mit einem an dem Abschnitt 22 angeformten Abschnitt oder Rinnensegment 25 ausgebildet, welches an der Oberseite des Formkörpers 21 offen und durch zwei Wandabschnitte 27 und 28 und einen Boden 29 begrenzt ist. Der Abschnitt 25 bzw. dessen Wandabschnitte 27 und 28 sind bogenförmig gekrümmt, und zwar derart, dass die Abschnitte 25 der in Umfangsrichtung des Rotors 4 aneinander anschließenden Verschließstationen 11 bzw. der hydraulischen Dichtungen 20 dieser Stationen einen sich aus den Abschnitten 25 oder Segmenten zusammen setzenden, die Maschinenachse MA konzentrisch umschließenden und oben offenen Ringkanal 26 bilden, der bezogen auf die Maschinenachse die Abschnitte 22 und damit die durch die Öffnungen 24 dieser Abschnitte hindurchgeführten Spindeln 15 außen umschließt.The sealing element 21 is further formed with a portion 22 formed on the portion or gutter segment 25 which is open at the top of the shaped body 21 and limited by two wall sections 27 and 28 and a bottom 29. The section 25 or its wall sections 27 and 28 are arcuately curved, in such a way that the sections 25 of the circumferentially of the rotor 4 adjoining Verschließstationen 11 and the hydraulic seals 20 of these stations composed of the sections 25 or segments together , the machine axis MA concentrically enclosing and open at the top annular channel 26, which surrounds the sections 22 and thus the guided through the openings 24 of these sections spindles 15 outside with respect to the machine axis.

Die Höhe, die die Wandabschnitte 27 und 28 in der Achsrichtung senkrecht zum Boden 29 und damit im eingebauten Zustand in der Achsrichtung parallel zur Maschinenachse MA aufweisen, ist beispielsweise gleich der entsprechenden Höhe des äußeren Wandabschnittes 22.2. Das Rinnensegment 26 steht über eine Öffnung 30 mit dem Ringkanal 23 in Verbindung. Die Öffnung 30 befindet sich dabei im Bereich des mit dem Boden des Ringkanals 23 niveaugleich oder etwa niveaugleich angeordneten Boden 29 des Rinnensegments 25.The height which the wall sections 27 and 28 have in the axial direction perpendicular to the floor 29 and thus in the installed state in the axial direction parallel to the machine axis MA is, for example, equal to the corresponding height of the outer wall section 22.2. The channel segment 26 is connected via an opening 30 with the annular channel 23 in connection. In this case, the opening 30 is located in the region of the bottom 29 of the trough segment 25 that is level with or at the same level as the bottom of the annular channel 23.

Im montierten Zustand ist der Formkörper 21 jeder hydraulischen Dichtung 20 an der Oberseite der Wandung 6 im Bereich einer in dieser Wandung vorgesehenen Öffnung 31 befestigt, und zwar derart, dass die Öffnung 24 deckungsgleich mit der Öffnung 31 liegt und der Ringkanal 23 sowie das Rinnensegment 25 jeweils zu der der Wandung 6 abgewandten Oberseite offen sind.In the assembled state, the molded body 21 of each hydraulic seal 20 is fixed to the top of the wall 6 in the region of an opening provided in this wall opening 31, in such a way that the opening 24 is congruent with the opening 31 and the annular channel 23 and the channel segment 25th are each open to the wall 6 facing away from the top.

Im montierten Zustand ist das Gehäuse 17 mit einem das untere Lager 19 aufweisenden Gehäuseabschnitt 17.1 mit dem äußeren Wandabschnitt 22.2 an der Oberseite dieses Wandabschnittes dicht verbunden.In the assembled state, the housing 17 with a lower bearing 19 having housing portion 17.1 with the outer wall portion 22.2 at the top of this wall portion is tightly connected.

Bestandteil jeder hydraulischen Dichtung 20 ist weiterhin ein als Formteil ausgebildetes napf- oder glockenartiges Dichtungselement 32, welches, wie insbesondere auch in der Figur 5 im Detail dargestellt ist, aus einem ringförmigen Abschnitt 33, der im montierten Zustand auf der Spindel 15 diese umgreifend dicht befestigt ist, und aus einem kreiszylinderförmigen Abschnitt 34 besteht, der im montierten Zustand die Achse der Spindel 17 konzentrisch und mit radialem Abstand umschließt und an seinem oberen Ende in den ringförmigen Abschnitt 33 übergeht. Der Abschnitt 34 ist so ausgebildet, dass er im montierten Zustand der jeweiligen hydraulischen Dichtung 20 in den Ringkanal 23 des Dichtungselementes 21 hineinreicht, und zwar derart, dass die kreiszylinderförmige Innenfläche und die ebenfalls kreiszylinderförmige Außenfläche des Abschnittes 34 jeweils von der Innenfläche der Wandabschnitte 22.1 und 22.2 sowie das untere freie Ende des Abschnitts 34 vom Boden des Ringkanals 23 beabstandet ist.Component of each hydraulic seal 20 is further formed as a molded part cup- or bell-shaped sealing element 32, which, as in particular in the FIG. 5 is shown in detail, from an annular portion 33 which is mounted in the mounted state on the spindle 15 surrounding this tightly, and consists of a circular cylindrical portion 34 which surrounds the axis of the spindle 17 concentrically and at a radial distance in the mounted state and at its upper end merges into the annular portion 33. The portion 34 is formed so that it extends in the assembled state of the respective hydraulic seal 20 in the annular channel 23 of the sealing member 21, in such a way that the circular cylindrical inner surface and the likewise circular cylindrical outer surface of the portion 34 each of the inner surface of the wall sections 22.1 and 22.2 and the lower free end of the portion 34 is spaced from the bottom of the annular channel 23.

Jede hydraulische Dichtung 20 weist weiterhin mehrere mechanische Dichtungselemente auf, und zwar bei der dargestellten Ausführungsform einen Dichtungsring 35, der den Übergang zwischen dem Gehäuseabschnitt 17.3 und den oberen Rand des Wandabschnittes 22.2 abdichtet, einen Dichtungsring 36, der den Spalt zwischen dem Abschnitt 33 und der Außenfläche der Spindel 17 abdichtet, sowie ein beispielsweise mit wenigstens einer Abstreiflippe ausgeführtes ringförmiges Dichtungselement 37 zwischen dem Abschnitt 33 des mit der Spindel 17 umlaufenden Dichtungselementes Formteils 32 und der Innenfläche der äußeren Wandung 22.2 im oberen Bereich dieser Wandung. Weitere, nicht dargestellte Dichtungen sind zwischen den einzelnen aneinander anschließenden Rinnensegmenten 25 vorgesehen, um so eine aus diesen Rinnensegmenten 25 bestehende, flüssigkeitsdichte Rinne 26 zu schaffen.Each hydraulic seal 20 further comprises a plurality of mechanical sealing elements, in the illustrated embodiment, a sealing ring 35 which seals the transition between the housing portion 17.3 and the upper edge of the wall portion 22.2, a sealing ring 36, the gap between the portion 33 and the Outer surface of the spindle 17 seals, as well as an example designed with at least one wiper lip annular seal member 37 between the portion 33 of the circumferential direction of the spindle 17 seal member molding 32 and the inner surface of the outer wall 22.2 in the upper region of this wall. Further seals, not shown, are provided between the individual adjoining groove segments 25 so as to create a liquid-tight groove 26 consisting of these groove segments 25.

Während des Betriebes sind die von den Rinnensegmenten 25 gebildete, die Maschinenachse MA konzentrisch umschließende Rinne 26 und damit über die Öffnungen 30 auch das jeweilige, von dem Abschnitt 34 des Dichtungselementes 32 nicht eingenommene Volumen des Ringkanals 23 jeder hydraulischen Dichtung 26 bis zu einem Niveau N mit einem flüssigen Dichtungs- oder Sterilisationsmedium gefüllt, wobei dieses Niveau N etwas unterhalb des Niveaus des oberen Randes des inneren Wandabschnitts 22.1 liegt. Durch den in den jeweiligen Ringkanal 23 hineinragenden Abschnitt 34 und durch das in dem Ringkanal 23 aufgenommene flüssige Dichtungs- oder Sterilisationsmedium ergibt sich an jeder Verschließstation 11 eine zuverlässige siphonartige Abdichtung im Bereich der Durchführung der Spindel 15. Das Niveau N des Dichtungs- oder Sterilisationsmediums wird beispielsweise über eine nicht dargestellte, niveaugesteuerte Versorgungseinheit gesteuert oder geregelt eingehalten.During operation, the channel 26 formed by the trough segments 25, the machine axis MA concentrically enclosing groove 26 and thus through the openings 30 and the respective, not occupied by the portion 34 of the sealing element 32 volume of the annular channel 23 of each hydraulic seal 26 up to a level N. with a liquid sealing or sterilizing medium filled, this level N is slightly below the level of the upper edge of the inner wall portion 22.1. By the projecting into the respective annular channel section 34 and by the recorded in the annular channel 23 liquid sealing or sterilization medium results in each Verschließstation 11 a reliable siphon-like seal in the field of implementation of the spindle 15. The level N of the sealing or sterilization medium is controlled or regulated, for example, via a level-controlled supply unit, not shown.

Die Erfindung wurde voranstehend an einem Ausführungsbeispiel beschrieben. Es versteht sich, dass zahlreiche Änderungen sowie Abwandlungen möglich sind, ohne dass dadurch der der Erfindung zugrundeliegende Erfindungsgedanke verlassen wird. So wurde vorstehend davon ausgegangen, dass die Dichtungen 20 zum dichten Durchführen der um ihre Spindelachsen rotierenden Spindeln 15 dienen. Selbstverständlich können Dichtungen 20 oder die diese aufweisenden Durchführungen auch für eine axiale und/oder radiale Bewegung der Spindel 15 oder eines anderen Funktionselementes einer Verschließstation ausgebildet sein, und zwar insbesondere bei entsprechender Anpassung der axialen Abmessungen der Dichtungselemente 21 und 32, d.h. insbesondere der Höhe der Wandabschnitte 22.1, 22.2, 27, 28 sowie insbesondere durch entsprechende Anpassung der axialen Abmessung des kreiszylinderförmigen Abschnittes 34.The invention has been described above by means of an embodiment. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention. Thus, it has been assumed above that the seals 20 serve to seal the spindles 15 rotating about their spindle axes. Of course, seals 20 or the bushings having them may also be designed for axial and / or radial movement of the spindle 15 or other functional element of a closing station, in particular with a corresponding adaptation of the axial dimensions of the sealing elements 21 and 32, i. in particular, the height of the wall sections 22.1, 22.2, 27, 28 and in particular by appropriate adaptation of the axial dimension of the circular cylindrical portion 34th

Die hydraulische Dichtung 20 stellt ein absolut dichtes und steriles Durchführen der Spindel 15 durch die Wandung 6 sicher, und zwar insbesondere auch dadurch, dass durch das in dem Ringkanal 23 aufgenommene flüssige Dichtungs- und/oder Sterilisationsmedium eine Sperre gebildet ist, die sich um den gesamten, in dieses Dichtungs- und/oder Sterilisationsmedium eingetauchten Abschnitt 34 erstreckt. Mit Ausnahme des gegen die Innenfläche des Wandabschnittes 22.1 anliegenden Dichtungselementes 37 erfolgt die Abdichtung ohne eine Berührung zwischen den Dichtungselementen 21 und 32.The hydraulic seal 20 ensures an absolutely dense and sterile passage of the spindle 15 through the wall 6, and in particular by the fact that formed by the recorded in the annular channel 23 liquid sealing and / or sterilization medium, a barrier which is formed around the entire immersed in this sealing and / or sterilizing medium portion 34 extends. With the exception of the sealing element 37 resting against the inner surface of the wall section 22.1, the sealing takes place without contact between the sealing elements 21 and 32.

Weiterhin ist die erfindungsgemäße Dichtung oder Durchführung selbstverständlich nicht nur für die Verwendung bei Verschließmaschinen geeignet, sondern auch für die Verwendung bei andere Behälterbehandlungsmaschinen, bei denen beispielsweise ein rotierendes und/oder axial und/oder radial bewegbares Funktionselement von der Umgebung oder einem Unsterilraum in einen Sterilraum von oben her mit einem Teilabschnitt hineinreicht.Furthermore, the seal or implementation according to the invention is of course not only suitable for use in capping machines, but also for use in other container treatment machines in which, for example, a rotating and / or axially and / or radially movable functional element from the environment or a non-sterile space in a sterile room from above with a partial section extends.
