Description

Die Erfindung bezieht sich auf ein Verfahren gemäß Ober begriff Patentanspruch 1 sowie auf eine Vorrichtung gemäß Oberbegriff Patentanspruch 17.The invention relates to a method according to Ober Concept of claim 1 and a device according to Preamble of claim 17.

Verfahren sowie Vorrichtungen zur Überkopf-Behandlung von Flaschen sind in unterschiedlichsten Ausführungen bekannt. Bekannt ist insbesondere auch eine nach Art eines Rinsers ausgebildete Vorrichtung, bei der die Flaschengreifer an einem um eine vertikale Achse umlaufenden Maschinenteil bzw. Rotor vorgesehen sind und die von den Flaschengreifern erfaßten, zunächst mit ihrem Boden nach unten weisenden Flaschen durch radiales Schwenken nach außen gewendet werden, so daß sich die Flaschen nach dem Wenden mit der Flaschen mündung über einen eine Düsenöffnung bildenden Düsenrohr für das Behandlungsmedium befinden. Dieses Düsenrohr wird zumindest dann, wenn die Behandlung mit einem gas- oder dampfförmigen Behandlungsmedium erfolgt, durch die Flaschen mündung von unten her in den Innenraum der gewendeten Flasche eingeführt. Probleme ergeben sich oftmals in bezug auf die geforderte Keimfreiheit der behandelten Flaschen, und zwar speziell auch in bezug auf die Keimfreiheit der Flaschen mündung.Processes and devices for overhead treatment of Bottles are known in various designs. A rinser type is also known in particular trained device in which the bottle gripper on a machine part rotating around a vertical axis or Rotor are provided and those of the bottle grippers detected, initially with their bottom pointing downwards Bottles are turned outwards by radial swiveling, so that the bottles after turning with the bottles mouth via a nozzle tube forming a nozzle opening the treatment medium. This nozzle pipe will at least if treatment with a gas or vaporous treatment medium takes place through the bottles Mouth from below into the interior of the flipped bottle introduced. Problems often arise in relation to the required sterility of the treated bottles, namely especially with regard to the sterility of the bottles muzzle.

Aufgabe der Erfindung ist es, ein Verfahren sowie eine Vorrichtung aufzuzeigen, die mit einfachen Mitteln die geforderte hohe Sterilität der behandelten Flaschen sicher stellt.The object of the invention is a method and a Show device that with simple means the required high sterility of the treated bottles poses.

Zur Lösung dieser Aufgabe ist ein Verfahren entsprechend dem kennzeichnenden Teil des Patentanspruches 1 und eine Vorrich tung zum Durchführen dieses Verfahrens entsprechend dem kennzeichnenden Teil des Patentanspruches 17 ausgeführt. To solve this problem, a method according to the characterizing part of claim 1 and a Vorrich device to perform this procedure according to characterizing part of claim 17 executed.

Bei der Erfindung erfolgt nach Beendigung wenigstens einer Behandlungsphase oder auf diese zeitlich folgend eine Beaufschlagung der Flaschenmündung der jeweiligen Flasche mit einem Strahl eines dampf- oder gasförmigen Mediums, und zwar aus einer Düsenöffnung, die mit Abstand der Flaschenmündung gegenüberliegend vorgesehen ist. Der aus der Düsenöffnung austretende Strahl läßt sich dabei so einstellen, daß er nicht, allenfalls nur ganz geringfügig in die jeweilige Flasche eintritt, aber an der Flaschenmündung eine radial nach außen und zumindest teilweise auch axial entlang der Außenfläche der Flasche verlaufende Strömung erzeugt. Ist das bei der Nachbehandlung verwendete Medium ein Sterilisations medium, z. B. Wasserdampf, so wird hiermit eine optimale Sterilisation der Flasche im Bereich der Flaschenmündung erreicht.In the invention, at least after completion one treatment phase or one following this Loading of the bottle mouth of the respective bottle with a jet of a vapor or gaseous medium, namely from a nozzle opening that is at a distance from the bottle mouth is provided opposite. The one from the nozzle opening emerging beam can be adjusted so that it not, at most only very slightly in the respective Bottle enters, but a radial one at the bottle mouth outwards and at least partially axially along the The surface of the bottle creates a flowing current. Is this medium used in the aftertreatment a sterilization medium, e.g. B. water vapor, this is an optimal Sterilization of the bottle in the area of the bottle mouth reached.

Das bei der Nachbehandlung verwendete Medium kann auch dazu dienen, an die Flaschenmündung gelangte Reste oder Tropfen eines flüssigen Behandlungsmediums (z. B. Wasser) zu entfernen oder zu verhindern, daß derartige Tropfen oder Reste in die Flasche gelangen. Diese Nachbehandlung, die mit dem Sterili sationsmedium (z. B. Wasserdampf) oder mit steriler Luft erfolgt, wird vor dem Zurückwenden und/oder beim Zurückwenden der Flasche in ihre ursprüngliche Ausgangslage vorgenommen und verhindert somit, daß bei diesem Zurückwenden Reste eines Behandlungsmediums und mit diesem Keime in den Innenraum der Flasche gelangen.The medium used in the aftertreatment can also do this serve, leftovers or drops at the bottle mouth a liquid treatment medium (e.g. water) or to prevent such drops or residues in the Bottle. This post-treatment that comes with the sterile medium (e.g. water vapor) or with sterile air is done before turning back and / or when turning back the bottle in its original position and thus prevents residues of a Treatment medium and with this germ in the interior of the Bottle.

Weiterbildungen der Erfindung sind Gegenstand der Unteran sprüche.Further developments of the invention are the subject of the Unteran claims.

Die Erfindung wird im folgenden anhand der Figuren an einem Ausführungsbeispiel erläutert. Es zeigen:The invention is illustrated below with the aid of the figures Exemplary embodiment explained. Show it:

Fig. 1 in sehr vereinfachter Darstellung und in Draufsicht eine Vorrichtung zum Behandeln von Flaschen in Form eines Rinsers umlaufender Bauart; Figure 1 in a very simplified representation and in plan view of a device for treating bottles in the form of a rinser rotating design.

Fig. 2 in vereinfachter Darstellung eine an einem Flaschen greifer gehaltene, gewendete Flasche sowie ein unter der Flasche angeordnetes Düsenrohr einer Behandlungs station. Fig. 2 in a simplified representation of a bottle gripper held, flipped bottle and a nozzle tube arranged under the bottle of a treatment station.

In den Figuren ist 1 der um eine vertikale Maschinenachse in Richtung des Pfeiles A umlaufende Rotor einer als Rinser ausgebildeten Vorrichtung zum Behandeln von Flaschen 2, die der Vorrichtung über einem Transporteur 3 und einem Ein laufstern 4 zugeführt werden und die nach dem Behandeln über einen Ausschubstern und einem Transporteur 6 abgeführt werden, auf dem die Flaschen 2 wiederum aufrechtstehend, d. h. mit ihrem Boden unten abgeführt werden.In the figures, 1 is the rotor rotating around a vertical machine axis in the direction of arrow A of a device designed as a rinser for treating bottles 2 , which are fed to the device via a conveyor 3 and a star wheel 4 and, after treatment, via an ejecting star and are carried away by a transporter 6 , on which the bottles 2 are in turn standing upright, that is to say are led away with their bottom at the bottom.

Jede einlaufende Flasche 2 wird von einem am Rotor 1 vor gesehenen Flaschengreifer 7 erfaßt, mit dem die jeweilige Flasche 2 zunächst gewendet wird, so daß der Flaschenboden 21 schließlich nach oben und die Flaschenmündung 2′′ nach unten weisen. Dieses Wenden, welches in einem ersten, auf den Einlaufstern 4 folgenden Winkelbereich I stattfindet, erfolgt so, daß die jeweilige Flasche 2 mit ihrem Flaschenboden 2′ radial nach außen geschwenkt wird. Nach dem Wenden erfolgt in einem weiteren, anschließenden Winkelbereich II das Behandeln der Flasche 2. In einem anschließenden Winkelbereich III der Drehbewegung des Rotors 1 wird die jeweilige Flasche 2 in ihre ursprüngliche Lage zurückgewendet und auf den Rotor 1 abgestellt. Die mit einer unterbrochenen Linie wiedergegebene Kurve 8 zeigt die vertikale Projektion des unteren Bereichs der Flaschen 2 bei umlaufenden Rotor 1.Each incoming bottle 2 is gripped by a bottle gripper 7 seen on the rotor 1 , with which the respective bottle 2 is first turned, so that the bottle bottom 21 finally points upwards and the bottle mouth 2 '' downwards. This turning, which takes place in a first, following the inlet star 4 following angular range I, is such that the respective bottle 2 with its bottle bottom 2 'is pivoted radially outwards. After turning, the bottle 2 is treated in a further, subsequent angular range II. In a subsequent angular range III of the rotary movement of the rotor 1 , the respective bottle 2 is turned back into its original position and placed on the rotor 1 . Curve 8, shown with a broken line, shows the vertical projection of the lower region of bottles 2 with rotating rotor 1 .

Bei der dargestellten Ausführungsform ist jedem Flaschen greifer 7 ein eine Behandlungsposition bildendes vertikales Düsenrohr 9 zugeordnet. Die Düsenrohre 9 sind am Rotor 1 in gleichen Winkelabständen um dessen Drehachse versetzt oder an einem nicht dargestellten Element des Flaschengreifers 7 vorgesehen, so daß sich jedes Düsenrohr 9 bei einer von dem zugehörigen Flaschengreifer 7 erfaßten und gewendeten Flasche 2 unterhalb dieser gewendeten Flasche befindet, und zwar achsgleich oder in etwa achsgleich mit der Achse der gewen deten Flasche 2, wie dies in der Fig. 2 dargestellt ist.In the illustrated embodiment, each bottle gripper 7 is assigned a vertical nozzle tube 9 forming a treatment position. The nozzle tubes 9 are offset on the rotor 1 at equal angular intervals about its axis of rotation or are provided on an element of the bottle gripper 7 , not shown, so that each nozzle tube 9 is located below a bottle 2 that is gripped and turned by the associated bottle gripper 7 , and although coaxially or approximately coaxially with the axis of the bottle 2 , as shown in FIG. 2.

Jedes Düsenrohr 9 besitzt einen Düsenkanal 10 mit einer oberen Austritts- bzw. Düsenöffnung 11 und ist in einem Lager- und Verteilerelement 12 für einen vorgegebenen Hub in vertikaler Richtung verschiebbar, und zwar durch ein Betäti gungselement 13, welches bei der dargestellten Ausführungs form von einem Pneumatik-Zylinder gebildet ist.Each nozzle tube 9 has a nozzle channel 10 with an upper outlet or nozzle opening 11 and is displaceable in a bearing and distributor element 12 for a predetermined stroke in the vertical direction, namely by a supply element 13 , which in the embodiment shown form of one Pneumatic cylinder is formed.

Über das Verteilerelement 12 und ein individuell steuerbares Ventil 14 ist jedes Düsenrohr 9 mit einer Leitung 15 für warmes Wasser verbunden. Weiterhin ist jedes Düsenrohr 9 über das Verteilerelement 12 und ein individuell steuerbares Ventil 18 mit einer Leitung 17 zum Zuführen von Dampf verbunden.Each nozzle tube 9 is connected to a line 15 for warm water via the distributor element 12 and an individually controllable valve 14 . Furthermore, each nozzle tube 9 is connected via the distributor element 12 and an individually controllable valve 18 to a line 17 for supplying steam.

Die Fig. 2 zeigt am unteren Ende des Düsenrohres 9 ein Steuerventil 18, mit welchem das jeweilige Düsenrohr 9 bzw. der dortige Kanal 10 entleert werden kann. Die Ventile 14, 16 und 18 sind beispielsweise elektrisch oder pneumatisch betätigte Ventile. Fig. 2 shows the lower end of the nozzle tube 9 a control valve 18, can be emptied with which the respective nozzle tube 9 or the local channel 10. The valves 14 , 16 and 18 are, for example, electrically or pneumatically operated valves.

Mit der beschriebenen Vorrichtung ist folgende Behandlung der Flaschen 2 möglich:With the device described, the following treatment of bottles 2 is possible:

1. First, each bottle 2 is turned in the manner described above, so that it points with its bottle bottom 2 'up and with its bottle mouth 2 ''down and the respective nozzle tube 9 is located below the bottle mouth 2 ''.
2. Then, by actuating the actuating device 13, the nozzle tube 9 is moved upward, ie an insertion of this nozzle tube into the bottle 2 , for example up to a length of 40-50 mm.
3. The respective bottle 2 is then rinsed and preheated at the same time, for which the valve 14 is opened and the interior of the bottle 2 is thus rinsed with warm water. The rinsing time is, for example, 1 second with a water consumption of approx. 110 ml. The temperature of the water is approx. 60-70 ° C. and the water pressure is approx. 2 bar.
The water emerging in the area of the bottle mouth 2 '' between the bottle 2 and the nozzle tube 9 is collected by suitable means and can, after corresponding filtering, be used at least partially again for rinsing further bottles 2 .
4. After rinsing, there is a break in treatment, during which the treated bottle can drip. During this treatment break, which is, for example, 0.5-2 sec., The respective nozzle tube 9 is emptied by opening the valve 18 .
5. After the bottle 2 drips out, it is treated inside with a sterilizing medium, ie in the embodiment shown with water vapor, which after opening the valve 16 enters the interior of this bottle via the nozzle tube 9 which is still inserted into the bottle 2 . The duration of this steam treatment is, for example, 2 seconds. The steam used for the steam treatment has a temperature of over 100 ° C. at a pressure of about 2 bar.
If there is a particularly high risk of breakage in the treated bottles 2 , as can be the case, for example, with older bottles that have already been used several times, it is also possible to reduce the vapor pressure to 1.2-1.5 bar and thus also the temperature of the Reduce steam accordingly.
6. At the end of the steam treatment, the respective nozzle tube 9 is moved out of the bottle 2 by means of the actuating device 13 for a subsequent treatment, in such a way that the nozzle opening 11 is at a short distance, for example at a distance of about 5 to 30 mm below the bottle mouth 2 '' is. If this state is reached, a brief steam flow or burst of steam takes place on the area of the bottle mouth 2 '' by opening the valve 16 . The opening time of the valve 16 is about 1 sec. It has been shown that by the arrangement of the nozzle opening 11 at a distance below the bottle mouth 2 '' and the resulting scattering of the steam jet emerging from the nozzle tube 9 during this treatment does not, at most only very slightly gets into the interior of the bottle 2 , but the steam of this steam jet flows very intensively around the area of the bottle mouth 2 '', especially also outside, and thereby ensures optimal sterilization of the bottle mouth 2 ''.
7. This is followed by the final draining of the respective bottle 2 . To drain the bottle bottom 2 ', the respective bottle 2 is pivoted relative to the vertical and remains in this pivoted position for a predetermined time. In bottles 2 with a flat bottom, this pivoting takes place from the turned, vertical position shown in FIG. 2 by approximately 20 to 30 °. In the case of bottles 2 with a deeper bottom, the swiveling takes place by approximately 30 to 45 °. The bottles 2 then remain in this swivel position for the entire dripping time.
8. At the end of the draining time, the bottles 2 are turned back and put down, with an aftertreatment corresponding to method step 6 preferably being carried out during the turning back. Here, the embodiment in which the nozzle tubes 9 are gripped on the bottles 7 and pivot with them, has the advantage that the position of the respective nozzle opening 11 relative to the bottle mouth 2 '' is retained when turning back.

Die Erfindung wurde voranstehend an einem Ausführungsbeispiel beschrieben. Es versteht sich, daß Änderungen sowie Abwand lungen möglich sind, ohne daß dadurch der die Erfindung tragende Erfindungsgedanke verlassen wird.The invention has been described above using an exemplary embodiment described. It is understood that changes as well as variance lungs are possible without thereby the invention fundamental inventive idea is left.

So kann die Vorrichtung beispielsweise für eine von der vorbeschriebenen Arbeitsweise abweichenden Behandlung der Flaschen 2 ausgebildet sein, und zwar beispielsweise in der Form, daß das Einführen des Düsenrohres 9 erst vor der Dampfbehandlung des Innenraumes der Flasche 2 erfolgt, während das vorausgehende Spülen und gegebenenfalls Vorwärmen der Flasche 2 mit dem sich unter der Flaschenmündung 2′′ befindlichen Düsenrohr 9 erfolgt. Weiterhin ist es auch möglich, auf die Behandlungspause zwischen dem Spülen der Flasche und der Dampfbehandlung zu verzichten.For example, the device can be designed for a treatment of the bottles 2 which differs from the above-described method of operation, for example in the form that the insertion of the nozzle tube 9 takes place only before the steam treatment of the interior of the bottle 2 , during the preceding rinsing and optionally preheating the bottle 2 with the nozzle tube 9 located under the bottle mouth 2 '' takes place. Furthermore, it is also possible to do without the treatment break between rinsing the bottle and steam treatment.

Schließlich ist es grundsätzlich auch möglich, zusätzlich zu oder anstelle des Verfahrensschrittes 6 einen Verfahrens schritt vorzusehen, bei dem das Düsenrohr 9 in der in der Fig. 2 dargestellten Weise mit seiner Düsenöffnung 11 in Abstand, d. h. beispielsweise in einem Abstand von etwa 5 bis 30 mm unterhalb der Flaschenmündung 2′′ angeordnet ist und auf der Düsenöffnung 11 ein von steriler Luft gebildeter Luftstrahl oder Luftstoß auf die Flaschenmündung 2′′ gerich tet wird. So wie der Dampfstrahl bei dem vorbeschriebenen Verfahrensschritt 6 dringt auch dieser Luftstrahl nicht oder allenfalls nur geringfügig in das Innere der Flasche 2 ein, wobei die Luft dieses Luftstrahles aber den Bereich der Flaschenmündung 2′′ insbesondere auch an der Außenseite der Flasche intensiv umströmt. Durch diese Behandlung mit steriler Luft werden eventuelle Wassertropfen an der Fla schenaußenfläche im Bereich der Flaschenmündung 2′′ wegge blasen, d. h. es wird insbesondere verhindert, daß solche Wassertropfen und evtl. in diesen enthaltene Keime beim Zurückwenden der jeweiligen Flasche 2 in den Innenraum dieser Flasche gelangen. Die Behandlung mit Luft trägt somit wesentlich zur Keimfreiheit der Flaschen 2 bei und erfolgt bevorzugt am Ende der Abtropfzeit beim Zurückwenden der jeweiligen Flasche. Wassertropfen, die sich vor der Behand lung mit steriler Luft bereits unmittelbar an der die Flaschenmündung 2′′ umgebenden Ringfläche befinden, werden durch die Behandlung mit steriler Luft radial nach außen weggedrängt.Finally, it is also fundamentally possible, in addition to or instead of method step 6 , to provide a method step in which the nozzle tube 9 with its nozzle opening 11 is at a distance in the manner shown in FIG. 2, that is to say for example at a distance of about 5 to 30 mm below the bottle mouth 2 '' is arranged and on the nozzle opening 11, an air jet or air blast formed by sterile air on the bottle mouth 2 '' is straightened. Just like the steam jet in process step 6 described above, this air jet does not penetrate, or at most only slightly, into the interior of the bottle 2 , but the air of this air jet, however, flows intensively around the area of the bottle mouth 2 '', particularly on the outside of the bottle. Through this treatment with sterile air, any water drops on the outer surface of the bottle in the area of the bottle mouth 2 '' blow away, that is, it is particularly prevented that such water drops and any germs contained therein when turning back the respective bottle 2 into the interior of this bottle reach. The treatment with air thus contributes significantly to the sterility of the bottles 2 and is preferably carried out at the end of the draining time when the respective bottle is turned back. Drops of water, which are already immediately before treatment with sterile air on the ring surface surrounding the bottle mouth 2 '', are pushed radially outwards by treatment with sterile air.
