In den Figuren ist 1 ein Füllelement, welches bei der dargestellten Ausführungsform als füllrohrloses Füllelement ausgebildet ist und mit seinem Füllelementgehäuse 2 zusammen mit einer Vielzahl gleichartiger Füllelemente am Umfang eines um eine vertikale Maschinenachse umlaufend antreibbaren Rotors 3 einer ansonsten nicht näher dargestellten Füllmaschine vorgesehen ist. In dem Gehäuse 2 sind in an sich bekannter Weise u. a. ein Flüssigkeitskanal mit einem Flüssigkeitsventil zur gesteuerten Abgabe des Füllgutes sowie wenigstens ein steuerbarer Gasweg vorgesehen, wobei der Flüssigkeitskanal mit einem am Rotor ausgebildeten Behälter oder Kanal zum Zuführen des Füllgutes und der wenigstens eine steuerbare Gasweg mit wenigstens einem im Rotor vorgesehenen Gaskanal in Verbindung stehen, wie dies dem Fachmann grundsätzlich bekannt ist.In the figures, 1 is a filling element which is formed in the illustrated embodiment as filling tube filling element and is provided with its Füllelementgehäuse 2 together with a plurality of similar filling elements on the circumference of a vertical axis of the machine rotatably driven rotor 3 of a filling machine otherwise not shown. In the housing 2, a liquid channel with a liquid valve for the controlled discharge of the contents and at least one controllable gas path are provided in a conventional manner, wherein the liquid channel with a rotor formed on the container or channel for supplying the contents and the at least one controllable gas path with at least one provided in the rotor gas channel in communication, as is generally known in the art.

An der Unterseite des Gehäuses 2 bildet der durch das nicht dargestellte Flüssigkeitsventil steuerbare Flüssigkeitskanal eine ringförmige Abgabeöffnung 4 für das flüssige Füllgut. Die Abgabeöffnung 4 umschließt ein Rückgasrohr 5, welches mit seiner Achse die vertikale Füllelementachse FA definiert und einen am unteren Ende offenen Rückgaskanal 5.1 bildet. Über diesen wird beispielsweise beim Füllen des in der Figur 1 in Dichtlage mit dem Füllelement 1 befindlichen Behälters 6 unter Gegendruck das durch das zufließende Füllgut aus dem Behälterinnenraum verdrängte Inertgas (CO2-Gas) abgeführt, wie dies dem Fachmann ebenfalls bekannt ist. Das Rückgasrohr 5 bzw. der Kanal 5.1 können auch noch weiteren Funktionen dienen, beispielsweise zum Spülen und/oder Vorspannen des Behälterinnenraumes mit Inertgas usw..At the bottom of the housing 2, the liquid channel, which can be controlled by the liquid valve, not shown, forms an annular discharge opening 4 for the liquid product. The discharge opening 4 encloses a return gas pipe 5, which defines with its axis the vertical Füllelementachse FA and forms an open at the lower end return gas channel 5.1. About this example, when filling in the FIG. 1 in a sealing position with the filling element 1 located container 6 under counterpressure the displaced by the inflowing medium from the container interior displaced inert gas (CO2 gas), as is also known in the art.

Bestandteil des Füllelementes 1 ist weiterhin ein Behälterträger 7 an der Unterseite des Gehäuses 2. Dieser Behälterträger 7 ist am unteren Ende zweier parallel zur Füllelementachse FA orientierter Führungsstangen 8 befestigt, die im Gehäuse 2 bzw. in dort gebildeten Führungen um einen vorgegebenen Axialhub verschiebbar und in Umlaufrichtung des Rotors 3 gegeneinander versetzt sind. Am oberen Ende sind die beiden Führungsstangen 8 jeweils am Ende eines Joches 9 miteinander verbunden, welches mit seiner Längserstreckung radial zur Füllelementachse FA orientiert und an welchem eine Steuerrolle 10 frei drehbar gelagert ist, die zumindest im normalen Füllbetrieb mit wenigstens einer ortsfesten Steuerkurve 11 derart zusammenwirkt, dass bei umlaufendem Rotor 3 jeder Behälterträger 7 im Bereich eines Behältereinlaufs der Füllmaschine abgesenkt ist, an dem die leeren Behälter 6 einzeln einer jeden von einem Füllelement 1 gebildeten Füllposition zugeführt werden, sowie an einem Behälterauslauf, an dem die gefüllten Behälter 6 von der jeweiligen Füllposition abgenommen werden, während im Winkelbereich der Drehbewegung des Rotors 3 auf den Behältereinlauf folgend und vor Erreichen des Behälterauslaufs die Behälterträger 7 derart angehoben werden, dass der jeweilige an einem Behälterträger 7 gehaltene Behälter 6 mit seiner Behältermündung 6.1 gegen eine die Abgabeöffnung 4 umschließende Ringdichtung 12 in Dichtlage angedrückt ist. Durch zwei jeweils eine Führungsstange 8 umschließende und zwischen der Oberseite des Gehäuses 2 und dem Joch 9 wirkende Druckfedern 13 ist jeder Behälterträger 7 in seine angehobene Stellung vorgespannt und wird durch die mit der Steuerkurve 11 zusammenwirkende Steuerrolle 10 am Behältereinlauf und Behälterauslauf sowie in dem Winkelbereich der Drehbewegung des Rotors 3 zwischen Behälterauslauf und Behältereinlauf gegen die Wirkung der Druckfedern 13 in die untere Position bewegt.This container carrier 7 is fixed at the lower end of two parallel to the Füllelementachse FA oriented guide rods 8, which in the housing 2 or in guides formed therein by a predetermined Axialhub displaced and in Circumferential direction of the rotor 3 are offset from each other. At the upper end, the two guide rods 8 are connected to each other at the end of a yoke 9, which is oriented with its longitudinal extent radially Füllelementachse FA and on which a control roller 10 is freely rotatably mounted, which cooperates with at least one stationary control cam 11 at least in normal filling operation in that, with the rotor 3 rotating, each container carrier 7 is lowered in the region of a container inlet of the filling machine, to which the empty containers 6 are supplied individually to each filling position formed by a filling element 1, and to a container outlet at which the filled containers 6 are of the respective one Filling position are removed, while in the angular range of rotation of the rotor 3 following the container inlet and before reaching the container outlet, the container carrier 7 are raised such that the respective held on a container carrier 7 container 6 with its container mouth 6.1 against e ine the discharge opening 4 enclosing ring seal 12 is pressed in sealing position.

Der Abschnitt 7.1.2 liegt weiterhin mit seinen Oberflächenseiten in Ebenen parallel zur Füllelementachse FA sowie parallel zu einer Tangente an eine gedachte kreisförmige Umlaufbahn, auf der sich die Füllelemente 1 bzw. deren Achsen FA bei umlaufender Füllmaschine bewegen.The container carrier 7 is u.a. from a support element 7.1, which is formed integrally with two webs 7.1.1 and a wall or leg-shaped section 7.1.2. The webs 7.1.1 are oriented with their longitudinal extent radially or approximately radially to the vertical machine axis and at their - related to the machine axis - the outer ends respectively connected to the lower end of one of the two guide rods 8. At their inner end, the webs 7.1.1 go over in the section 7.1.2, which connects the two webs together at these ends and projects downwardly, in the direction of the Füllelementachse FA on the side facing away from the housing 2 underside of the webs 7.1.1. The section 7.1.2 continues to lie with its surface sides in planes parallel to the Füllelementachse FA and parallel to a tangent to an imaginary circular orbit on which the filling elements 1 and their axes FA move with rotating filling machine.

An der Unterseite des Abschnitts 7.1.2 ist eine gabelartige Tragplatte 7.2 des Behälterträgers 7 befestigt. Diese Tragplatte 7.2, die mit ihren Oberflächenseiten in Ebenen senkrecht zur Füllelementachse FA orientiert ist, erstreckt sich von dem der Füllelementachse FA beabstandeten Abschnitt 7.1.2 bezogen auf die vertikale Maschinenachse radial nach außen bis in den Bereich der Füllelementachse FA und bildet an der bezogen auf die Maschinenachse radial außenliegenden Seite eine zu diese Seite hin offene Ausnehmung 14. Mit dieser hintergreift die Tragplatte 7.2 den jeweiligen von dem Füllelement 1 aufgenommenen Behälter 6 an einem unterhalb der Behältermündung 6.1 ausgebildeten Trag- oder Behälterflansch 6.2, sodass dieser Behälter 6 an seinem Behälterflansch 6.2 hängend am Behälterträger 7 gehalten und von diesem mit der Behältermündung 6.1 in Dichtlage gegen die Ringdichtung 12 angepresst ist.At the bottom of section 7.1.2, a fork-like support plate 7.2 of the container carrier 7 is attached. This support plate 7.2, which is oriented with its surface sides in planes perpendicular to Füllelementachse FA, extending from the Füllelementachse FA spaced section 7.1.2 relative to the vertical axis of the machine radially outward to the region of the Füllelementachse FA and forms at the related With this, the support plate 7.2 engages behind the respective container 6 received by the filling element 1 at a support or container flange 6.2 formed below the container mouth 6.1, so that this container 6 at its container flange 6.2 suspended on the container carrier 7 and pressed by this with the container mouth 6.1 in sealing position against the annular seal 12.

Wie die Figuren zeigen, sind die Abgabeöffnung 4, das untere Ende des Rückgasrohres 5 sowie die Ringdichtung 12 innerhalb einer Ausnehmung 15 vorgesehen, die in einem über die Unterseite des Gehäuses 2 wegstehenden Fortsatz 2.1 gebildet und an ihrem unteren, dem Gehäuse 2 abgewandten Ende offen ist. Der in Dichtlage mit dem Füllelement 1 befindliche Behälter 6 reicht mit seinem die Behältermündung 6.1 aufweisenden Ende in die Ausnehmung 14 hinein, die dadurch auch der Zentrierung des Behälters 6 am Füllelement 1 dient. Wie die Figur 1 zeigt, wird der Gehäusevorsprung 2.1 bei in Dichtlage mit dem Füllelement 1 befindlichem Behälter 7 von den beiden, voneinander beabstandeten und in Drehrichtung des Rotors 3 aufeinander folgenden Stegen 7.1.1 gabelartig umgriffen, d. h. der Gehäusevorsprung 2.1 steht durch die zwischen den Stegen 7.1.1 gebildete Öffnung über die dem Gehäuse 2 abgewandten Unterseite der Stege 7.1.1 vor.As the figures show, the discharge opening 4, the lower end of the return gas pipe 5 and the annular seal 12 are provided within a recess 15 which formed in a projecting beyond the bottom of the housing 2 extension 2.1 and open at its lower, the housing 2 facing away from the end is. The container 6 located in sealing position with the filling element 1 extends with its end having the container mouth 6.1 into the recess 14, which thereby also serves to center the container 6 on the filling element 1. As the FIG. 1 shows, the housing projection 2.1 is umbelgriffen with befindlichem in sealing position with the filling element 1 container 7 of the two, spaced apart and in the direction of rotation of the rotor 3 consecutive webs 7.1.1 forked, ie the housing projection 2.1 stands by the between the webs 7.1.1 formed opening on the housing 2 facing away from the underside of the webs 7.1.1 before.

Von Zeit zu Zeit ist ein Reinigen oder Spülen der Füllmaschine, deren Füllelemente 1 und dabei insbesondere auch der in diesen Füllelementen 1 ausgebildeten Flüssigkeits- und/oder Gaswege, einschl. des Rückgaskanals 5.1 erforderlich. Bei diesem Reinigen und/oder Spülen (auch als CIP-Reinigung bezeichnet) werden nicht nur die verschiedenen Flüssigkeits- und/oder Gaswege sämtlicher Füllelemente 1 der Füllmaschine von den Reinigungs- und/oder Spülmedien durchströmt, sondern es ist auch erforderlich, sämtliche mit Flächen des Behälters insbesondere im Bereich der Behältermündung 6.1 in Berührung kommende Flächen des jeweiligen Füllelementes 1 zu reinigen und dabei speziell auch die Ringdichtung 12, die Innenflächen der Ausnehmung 15 sowie das Rückgasrohr 5.From time to time, a cleaning or rinsing of the filling machine, the filling elements 1 and in particular also the formed in these filling elements 1 liquid and / or gas paths, incl. The return gas channel 5.1 is required. In this cleaning and / or rinsing (also referred to as CIP cleaning) not only the various liquid and / or gas paths of all filling elements 1 of the filling machine are flowed through by the cleaning and / or rinsing media, but it is also necessary, all with surfaces to clean the container in particular in the area of the container mouth 6.1 coming into contact surfaces of the respective filling element 1 and in particular also the ring seal 12, the inner surfaces of the recess 15 and the return gas pipe. 5

Für die Reinigung wird der Gehäusevorsprung 2.1 jedes Füllelementes 1 an seinem unteren, offenen Ende durch eine bei der dargestellten Ausführungsform rechteckförmige Spülplatte 16 dicht verschlossen, wobei jedem Füllelement 1 eine eigene Spülplatte 16 zugeordnet ist, die dann mit ihren Oberflächenseiten in Ebenen senkrecht zur Füllelementachse FA angeordnet ist. Die Spülplatte 16, die beispielsweise aus Metall oder einem geeigneten Kunststoff gefertigt ist, ist mit ihren beiden, sich in etwa radial zur Maschinenachse erstreckenden Längsseiten an dem Tragelement 7.1 bzw. an den einander zugewandten Längsseiten der Stege 7.1.1 geführt. Hierfür weisen die Stege 7.1.1 an diesen Längsseiten jeweils eine Führungsnut 17 auf, in die jeweils ein Längsrand der Spülplatte 16 eingreift.For cleaning, the housing projection 2.1 of each filling element 1 is sealed at its lower, open end by a rectangular in the illustrated embodiment flushing plate 16, each filling element 1 is assigned its own flushing plate 16, which then with their surface sides in planes perpendicular to Füllelementachse FA is arranged. The flushing plate 16, which is made for example of metal or a suitable plastic, is guided with its two, approximately radially to the machine axis extending longitudinal sides of the support member 7.1 and on the mutually facing longitudinal sides of the webs 7.1.1. For this purpose, the webs 7.1.1 on these longitudinal sides in each case a guide groove 17, in each of which a longitudinal edge of the flushing plate 16 engages.

In dieser Führung ist die Spülplatte 16 radial zur Maschinenachse aus einer Nichtgebrauchs- oder Ausgangsposition, in der sich die Spülplatte 16 im normalen Füllbetrieb der Füllmaschine befindet und die in der Figur 1 dargestellt ist, radial nach Außen (Pfeil A der Figur 2) in eine Spülposition bewegbar, die in der Figur 2 dargestellt ist und in der sich die Spülplatte 16 mit einer an ihrer Oberseite vorgesehenen Dichtung 16.1 unmittelbar unterhalb des offenen Endes der Ausnehmung 15 befindet, sodass die Spülplatte 16 dann durch Anheben des Behälterträgers 7 mit ihrer Dichtung 16.1 in Dichtlage gegen den unteren, die Öffnung der Ausnehmung 15 umschließenden Rand 2.1.1 des Gehäusevorsprunges 2.1 gebracht werden kann. Hierdurch bildet die Ausnehmung 15 einen geschlossenen Spülraum, der dann von dem jeweiligen Reinigungs- oder Spülmedium zum Reinigen und/oder Spülen aller Flüssigkeits- und Gaswege sowie aller kritischen Flächen durchströmt werden kann. Das Reinigungs- oder Spülmedium fließt dem Spülraum beispielsweise über den Gaskanal 5.1 zu und wird über die Abgabeöffnung 4 abgeführt. Auch eine umgekehrte Strömungsrichtung und/oder ein Wechseln der Strömungsrichtung während der Reinigungs- oder Spülphase sind möglich.In this guide, the flushing plate 16 is radial to the machine axis from a non-use or initial position, in which the flushing plate 16 in the normal filling operation the filling machine is located and in the FIG. 1 is shown, radially outward (arrow A of FIG. 2 ) movable in a rinsing position, in the FIG. 2 is shown and in which the flushing plate 16 is provided with a provided on its upper side seal 16.1 immediately below the open end of the recess 15, so that the flushing plate 16 then by lifting the container support 7 with its seal 16.1 in sealing position against the lower, the opening of the Recess 15 enclosing edge 2.1.1 of the housing projection 2.1 can be brought. As a result, the recess 15 forms a closed washing compartment, which can then be flowed through by the respective cleaning or rinsing medium for cleaning and / or rinsing all liquid and gas paths and all critical surfaces. The cleaning or rinsing medium flows to the washing compartment, for example via the gas channel 5.1 and is discharged via the discharge opening 4. A reverse flow direction and / or a change of the flow direction during the cleaning or rinsing phase are possible.

Zur Vorbereitung der Reinigungs- oder Spülphase wird somit jede Spülplatte 16 bei abgesenktem Behälterträger 7 aus ihrer Ausgangsposition radial nach Außen in die Spülposition bewegt, sodass sich die Dichtung 16.1 unmittelbar unter dem Gehäusevorsprung 2.1 befindet. Durch Anheben des Behälterträgers 7 wird die Spülplatte 16 mit ihrer Dichtung 16.1 in Dichtlage gegen den Rand 2.1.1 gebracht. Nach Beendigung der Reinigungs- oder Spülphase und nach Absenken des Behälterträgers 7 wird die jeweilige Spülplatte 16 radial nach Innen aus der Spülposition in die Ausgangsposition bewegt. Das Reinigen oder Spülen der Füllelemente 1 erfolgt bei umlaufender Maschine.In order to prepare the cleaning or rinsing phase, each rinsing plate 16 is thus moved radially outwardly into the rinsing position when the container carrier 7 is lowered, so that the seal 16. 1 is located directly beneath the housing protrusion 2. By lifting the container support 7, the flushing plate 16 is brought with its seal 16.1 in sealing position against the edge 2.1.1. After completion of the cleaning or rinsing phase and after lowering the container carrier 7, the respective flushing plate 16 is moved radially inwardly from the rinsing position to the starting position. The cleaning or rinsing of the filling elements 1 takes place when the machine is rotating.

Das Bewegen der Spülplatten 16 sämtlicher Füllelemente 1 der Füllmaschine aus der Ausgangsposition in die Spülposition (Pfeil A) bzw. aus der Spülposition in die Ausgangsposition (Pfeil B der Figur 1) erfolgt bei der dargestellten Ausführungsform automatisch über einen Stellantrieb, von dem in den Figuren lediglich eine von einem U-Profil gebildete Führung bzw. ein Mitnehmer 18 dargestellt ist. Jedem Füllelement 1 ist beispielsweise ein solcher Mitnehmer 18 zugeordnet, der radial zur Maschinenachse verschiebbar am Rotor 3 oder an einem Element dieses Rotors vorgesehen und dem jeweils ein Betätigungselement, beispielsweise ein Pneumatikzylinder für die radiale Bewegung zugeordnet ist. Auch andere Ausbildungen sind denkbar, beispielsweise auch eine mechanische Kopplung mehrerer Mitnehmer 18 mit einem gemeinsamen Stellantrieb. Weiterhin ist es möglich den Mitnehmer 18 nur einmal für alle Füllelemente 1 gemeinsam an einer bestimmten Position der Umlaufbahn der Füllelemente 1 und mit dem Rotor 3 nicht mitdrehend vorzusehen, beispielsweise im Winkelbereich der Drehbewegung des Rotors 3 zwischen Behälterauslauf und Behältereinlauf und/oder zum Bewegen der Spülplatten 16 zwischen der Ausgangsposition und der Spülposition den oder die Mitnehmer 18 mit einem manuell betätigbaren Betätigungselement antriebsmäßig zu koppeln.Moving the flushing plates 16 of all filling elements 1 of the filling machine from the starting position into the flushing position (arrow A) or from the flushing position into the starting position (arrow B of FIG FIG. 1 ) takes place in the illustrated embodiment automatically via an actuator, of which in the figures, only one of a U-shaped guide or a driver 18 is shown. Each filling element 1, for example, associated with such a driver 18 which is provided radially to the machine axis displaceable on the rotor 3 or on an element of this rotor and the respective one actuating element, for example, a pneumatic cylinder for the radial movement is assigned. Other embodiments are conceivable, for example, a mechanical coupling of several drivers 18 with a common actuator. Furthermore, it is possible the driver 18 only once for all filling elements 1 together at a certain position of Circulating path of the filling elements 1 and not rotatably provided with the rotor 3, for example in the angular range of rotation of the rotor 3 between the container outlet and container inlet and / or moving the flushing plates 16 between the starting position and the rinsing position or the driver 18 with a manually operable actuator drivingly to pair.

Jede Spülplatte 16 besitzt an ihrer bezogen auf die vertikale Maschinenachse radial innen liegenden Seite einen mit einem Ende an der Spülplatte 16 befestigten und über die Unterseite der Spülplatte wegstehenden Mitnehmerzapfen 19, der in den Mitnehmer 18 hineinreicht, und zwar sowohl bei abgesenktem Behälterträger 7 als auch bei angehobenen Behälterträger 7, sodass unabhängig von der Position des Behälterträgers 7 eine antriebsmäßige Verbindung zwischen der Spülplatte 16 und dem Mitnehmer 18 besteht. Der oder die Mitnehmer 18 befinden sich bei dieser Ausführung bezogen auf die vertikale Maschinenachse radial innerhalb der kreisförmigen Bewegungsbahn, auf der sich die Füllelemente 1 bei umlaufendem Rotor bewegen.Each flushing plate 16 has on its relative to the vertical axis of the machine radially inner side attached to one end of the flushing plate 16 and wegstehende over the underside of the flush plate driving pin 19 which extends into the driver 18, both with lowered container carrier 7 and with raised container carrier 7, so that regardless of the position of the container carrier 7 is a driving connection between the flushing plate 16 and the driver 18. The one or more drivers 18 are in this embodiment with respect to the vertical machine axis radially within the circular path of movement, on which the filling elements 1 move with rotating rotor.

In der Figur 1 ist mit 16a eine Spülplatte bezeichnet, die bei einer Füllmaschine verwendet werden kann, welche die Spülplatten 16 und die Betätigungsmittel (Mitnehmer 18, Mitnehmerzapfen 19 usw.) für diese Spülplatten 16 nicht aufweist. Die Spülplatte 16a, die wiederum für jedes Füllelement 1 der Füllmaschine vorgesehen ist, wird für die Vorbereitung der Reinigungs- oder Spülphase jeweils bei abgesenktem Behälterträger 7 mit ihren Längsseiten in die Nuten 17 dieses Behälterträgers eingesetzt, sodass sich die Dichtung 16a.1 unterhalb des Gehäusevorsprunges 2.1 bzw. des offenen Endes der Ausnehmung 15 befindet und dann durch Anheben des Behälterträgers 7 die Spülplatte 16a mit ihrer Dichtung 16a.1 wiederum in Dichtlage mit dem Rand 2.1.1 gebracht werden kann. Nach dem Spülen bzw. Reinigen wird jede Spülplatte 16a nach dem Absenken des Behälterträgers 7 wieder entnommen.In the FIG. 1 16a denotes a flushing plate which can be used in a filling machine which does not have the flushing plates 16 and the actuating means (catch 18, driving pins 19, etc.) for these flushing plates 16. The rinsing plate 16a, which in turn is provided for each filling element 1 of the filling machine, is inserted into the grooves 17 of this container carrier for the preparation of the cleaning or rinsing phase in each case with the container carrier 7 lowered, so that the seal 16a.1 below the housing projection 2.1 or the open end of the recess 15 and then by lifting the container support 7, the flushing plate 16a with its seal 16a.1 turn in sealing position with the edge 2.1.1 can be brought. After rinsing or cleaning, each rinsing plate 16a is removed again after the container carrier 7 has been lowered.

Den beschriebenen Ausführungsbeispielen ist gemeinsam, dass das Bewegen der Spülplatten 16 zwischen der Ausgangsposition und der Spülposition bzw. das Einsetzen und Entnehmen der Spülplatten 16a dort erfolgt, wo die Behälterträger 7 durch die wenigstens eine Steuerkurve 11 abgesenkt sind, d.h. am Behältereinlauf oder Behälterauslauf oder aber im Winkelbereich zwischen dem Behälterauslauf und dem Behältereinlauf. Insbesondere bei dem manuellen Einlegen der Spülplatten 16a wird hierfür der Rotor 3 der Füllmaschine mit geringer Drehzahl oder aber auch getaktet angetrieben.The described embodiments have in common that the movement of the purging plates 16 between the starting position and the rinsing position or the insertion and removal of the purging plates 16a takes place where the container carrier 7 are lowered by the at least one control cam 11, ie at the container inlet or container outlet or in the angular range between the container outlet and the container inlet. Especially when manually inserting the flushing plates 16a, the rotor 3 of the filling machine for this purpose is driven at low speed or clocked.

Diese Ausbildung hat den Vorteil, dass für die Einleitung und Beendigung der Reinigungs oder Spülphase grundsätzlich keine weiteren Änderungen und/oder Einstellungen an der Füllmaschine notwendig sind, insbesondere auch keine Einstellungen der wenigstens einen Steuerkurve 11 oder weiterer Führungs- oder Steuerelemente. Grundsätzlich sind aber auch andere Verfahrensweisen für die Einleitung und Beendigung der Reinigungs- oder Spülphase denkbar.This design has the advantage that basically no further changes and / or adjustments to the filling machine are necessary for the initiation and termination of the cleaning or rinsing phase, in particular also no adjustments of the at least one control cam 11 or other guiding or control elements. In principle, however, other procedures for the initiation and termination of the cleaning or rinsing phase are conceivable.

Wie nämlich die Figuren zeigen, befindet sich bei einem in Dichtlage mit dem Füllelement 1 angeordneten Behälter 6 beispielsweise die Dichtung 16.1 in Richtung der Achse FA in einem größeren radialen Abstand vom Rand 2.1.1 als die gegen die Behältermündung 6.1 anliegende Unterseite der Ringdichtung 12. Der Hub, um den der Behälterträger 7 aus seiner in der Figur 1 dargestellten Position für die Aufnahme oder Freigabe eines Behälters 6 durch die Steuerkurve 11 nach unten bewegt werden muss, kann also kleiner sein als derjenige Hub, der erforderlich ist, um die Spülplatte 16 soweit abzusenken, wie dies für ihre Bewegung zwischen der Ausgangsposition und der Spülposition notwendig ist.Namely, as shown in the figures, is located at a sealing position with the filling element 1 arranged container 6, for example, the seal 16.1 in the direction of the axis FA at a greater radial distance from the edge 2.1.1 as against the container mouth 6.1 fitting underside of the ring seal 12th The hub to the container carrier 7 from his in the FIG. 1 shown position for receiving or releasing a container 6 by the control cam 11 must be moved downwards, so may be less than the one stroke that is required to lower the purge plate 16 as far as this for their movement between the starting position and the rinsing position necessary is.

Hierdurch besteht die Möglichkeit, zusätzlich zu der wenigstens einen Steuerkurve 11, welche die Bewegung der Behälterträger 7 während des normalen Füllvorgangs steuert, eine Steuerkurve 11.1 vorzusehen, die ebenfalls mit den Steuerrollen 10 der Füllelemente zusammenwirkt und mit der die Behälterträger 7 nur während der Vorbereitung und Beendigung der Reinigungs- und Spülphase weiter als durch die Steuerkurve 11 nach unten bewegt werden. Während der Reinigungs- und Spülphase ist die Steuerkurve 11.1 dann unwirksam geschaltet, sodass während der Reinigungs- und Spülphase trotz der mit der Steuerkurve 11 zusammenwirkenden Rollen 10 in jeder Drehstellung des Rotors 3 die Dichtungen 16.1 oder 16a.1 sämtlicher Spülplatten 16 bzw. 16a durch die Druckfedern 13 zur Schaffung geschlossener Spülräume ausreichend gegen den jeweiligen Rand 2.1.1 angedrückt anliegen.This makes it possible, in addition to the at least one control cam 11, which controls the movement of the container carrier 7 during the normal filling process, to provide a control cam 11.1, which also cooperates with the control rollers 10 of the filling elements and with the container carrier 7 only during preparation and Completion of the cleaning and rinsing phase continues to be moved by the control cam 11 down. During the cleaning and rinsing phase, the control cam 11.1 is then disabled, so that during the cleaning and rinsing despite the co-operating with the cam 11 rollers 10 in each rotational position of the rotor 3, the seals 16.1 or 16a.1 all Spülplatten 16 or 16a the compression springs 13 abut sufficiently against the respective edge 2.1.1 to create closed washrooms.

Die Erfindung wurde voranstehend an Ausführungsbeispielen beschrieben. Es versteht sich, dass zahlreiche Änderungen sowie Abwandlungen möglich sind, ohne dass dadurch der der Erfindung zugrunde liegende Erfindungsgedanke verlassen wird.The invention has been described above by means of exemplary embodiments. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention.
