Es zeigen:following The present invention is purely exemplary by way of an advantageous embodiment and with reference to the accompanying drawings. Show it:

1 eine perspektivische Ansicht einer Vorrichtung zum sterilen Verbinden zweier Schlauchenden; und 1 a perspective view of a device for the sterile connection of two hose ends; and

2 eine teilweise geschnittene Draufsicht auf die Vorrichtung von 1. 2 a partially sectioned plan view of the device of 1 ,

1 zeigt eine stark schematische und vereinfachte Darstellung einer Vorrichtung zum sterilen Verbinden zweier Schlauchenden aus thermoplastischem Material, wobei die Vorrichtung eine Klemmeinrichtung 10 für die Schlauchenden, eine Schneideinrichtung 12 und eine bei dem dargestellten Ausführungsbeispiel in die Schneideinrichtung integrierte Heizeinrichtung umfasst. 1 shows a highly schematic and simplified representation of a device for the sterile connection of two hose ends made of thermoplastic material, wherein the device comprises a clamping device 10 for the hose ends, a cutting device 12 and a heating device integrated in the cutting device in the illustrated embodiment.

Die in den 1 und 2 dargestellte Klemmeinrichtung 10 weist zwei Klemmbackenpaare 12 und 14 auf, die jeweils mit parallelen Aufnahmerillen für die Schlauchenden versehen sind. Wie insbesondere 2 zeigt, können mit Hilfe der Klemmeinrichtung 10 die Schlauchenden von zwei Kunststoffschläuchen A und B geklemmt werden, wobei die beiden Schläuche A und B aus entgegengesetzten Richtungen in die Klemmeinrichtung 10 eingeführt werden, so dass die Schlauchenden mit ihren Endabschnitten einander antiparallel überlappen. Hierbei ist zwischen den Klemmelementen 12 und 14 eine Durchtrittsöffnung vorgesehen, durch die ein Schneidelement der Schneideinrichtung 12 hindurchgeführt werden kann, um die Endabschnitte der jeweiligen Schlauchenden abzuschneiden.The in the 1 and 2 illustrated clamping device 10 has two jaw pairs 12 and 14 on, which are each provided with parallel receiving grooves for the hose ends. In particular 2 shows, with the help of the clamping device 10 the hose ends of two plastic hoses A and B are clamped, the two hoses A and B from opposite directions in the clamping device 10 are introduced so that the hose ends overlap each other with their end portions antiparallel. Here is between the clamping elements 12 and 14 a passage opening provided by which a cutting element of the cutting device 12 can be passed to cut off the end portions of the respective hose ends.

Wie die vergrößerte Darstellung in 1 zeigt, ist die Schneideinrichtung 12 in einem kassettenartigen Gehäuse 16 angeordnet, in dem als Schneidelement ein auf einer Vorratsspule 18 aufgewickeltes Metallband 20 vorgesehen ist, das eine Länge von etwa 100 m aufweist. Ferner ist in dem Gehäuse 16 eine Leerspule 22 vorgesehen, auf der das freie Ende des Metallbandes 20 aufgewickelt ist, so dass durch Drehen der Leerspule 22 das Metallband 20 von der Vorratsspule 18 abgewickelt, über Umlenkelemente 24 und 26 geführt und auf der Vorratsspule wieder aufgewickelt wird.Like the enlarged view in 1 shows is the cutter 12 in a cassette-like housing 16 arranged in which as a cutting element on a supply reel 18 wound up metal band 20 is provided, which has a length of about 100 m. Further, in the housing 16 an empty spool 22 provided on the the free end of the metal band 20 is wound, so by turning the empty spool 22 the metal band 20 from the supply reel 18 unwound, over deflecting elements 24 and 26 guided and wound up on the supply reel.

1 lässt gut erkennen, dass das Gehäuse 16 ähnlich einer VHS-Videokassette ausgebildet ist und an seiner Unterseite zwei Durchtrittsöffnungen für Antriebswellen 28 und 30 aufweist. Um ein Überlappen von Klemmeinrichtung 10 und Schneideinrichtung 12 zu ermöglichen, weist das Gehäuse eine sich durch das Gehäuse und bis zum Rand des Gehäuses 16 erstreckende Aussparung 32 auf, in welche die Klemmeinrichtung 10 eintauchen kann (vgl. 1), wenn die Klemmeinrichtung und die Schneideinrichtung relativ zueinander in vertikaler Richtung bewegt werden. Auf diese Weise ergibt sich eine in Draufsicht U-förmige Gestaltung des Gehäuses 16, wobei das Metallband 20 an den vorderen Schenkelenden des Gehäuses 16 aus dem Gehäuse heraus und in das Gehäuse hineingeführt ist. 1 makes it easy to see that the case 16 similar to a VHS video cassette is formed and on its underside two passages for drive shafts 28 and 30 having. To overlap of clamping device 10 and cutting device 12 to allow the housing has a through the housing and to the edge of the housing 16 extending recess 32 on, in which the clamping device 10 can submerge (cf. 1 ), when the clamping device and the cutting device are moved relative to each other in the vertical direction. In this way results in a top view U-shaped design of the housing 16 where the metal band 20 at the front leg ends of the housing 16 out of the housing and out into the housing.

Wie in 1 schematisch angedeutet ist, ist innerhalb der Vorrichtung eine Heizeinrichtung 34 in Form eines HF-Generators vorgesehen, die mit zwei an der Schneideinrichtung 12 vorgesehenen elektrischen Anschlüssen 36 und 38 zusammenwirkt, um den zwischen den Kontakten 36 und 38 befindlichen Bandabschnitt des Metallbandes 20 zu erwärmen, indem dieser mit einem hochfrequenten Heizstrom beaufschlagt wird. Bei der dargestellten Ausführungsform sind die beiden Anschlüsse 36 und 38 in das Gehäuse 16 integriert und als zwei voneinander beabstandete Induktionsschleifen ausgebildet, die das Metallband umgeben und mittels Induktion auf eine Temperatur von etwa 320°C erwärmen.As in 1 is indicated schematically, is within the device a heater 34 in the form of an HF generator provided with two on the cutting device 12 provided electrical connections 36 and 38 interacts with the one between the contacts 36 and 38 located band portion of the metal strip 20 to heat by this is acted upon by a high-frequency heating current. In the illustrated embodiment, the two terminals 36 and 38 in the case 16 integrated and formed as two spaced-apart induction loops that surround the metal strip and heated by induction to a temperature of about 320 ° C.

Innerhalb des als Einwegkassette ausgebildeten Gehäuses 16 ist ferner ein mittels Federkraft an das aufgewickelte Metallband 20 angestellter Inkrementalgeber 42 vorgesehen, mit dessen Hilfe eine Mikroprozessorsteuerung 44 (1) so kontrolliert werden kann, dass ein in der Vorrichtung vorgesehener Antriebsmotor 40 jeweils einen gewünschten Bandabschnitt von der Vorratsspule 18 abwickelt. Hierbei kann der Antriebsmotor 40 entweder über ein Getriebe auf die Vorratsspule 18 und die Leerspule 22 wirken. Alternativ kann der Antriebsmotor 40 lediglich auf die Leerspule 22 wirken, wobei dann für die Vorratsspule 18 eine Bremseinrichtung vorgesehen ist, mit deren Hilfe ein ordnungsgemäßes Abwickeln des Metallbandes sichergestellt ist.Within the designed as a disposable cassette housing 16 is also a means of spring force to the wound metal band 20 Employed incremental encoder 42 provided with the help of a microprocessor control 44 ( 1 ) can be controlled so that a provided in the device drive motor 40 each a desired band portion of the supply spool 18 unwinds. Here, the drive motor 40 either via a gear on the supply reel 18 and the empty spool 22 Act. Alternatively, the drive motor 40 only on the empty spool 22 act, in which case for the supply reel 18 a braking device is provided, with the help of a proper unwinding of the metal strip is ensured.

In 1 bezeichnet ferner das Bezugszeichen 46 einen mechanischen Antrieb, der einerseits die Klemmelemente 12 und 14 betätigt und andererseits eine Relativbewegung (in 1 in vertikaler Richtung) zwischen Schneideinrichtung 12 und Klemmeinrichtung 10 um einen Hub von etwa 40–50 mm bewirkt.In 1 also denotes the reference numeral 46 a mechanical drive, on the one hand, the clamping elements 12 and 14 actuated and on the other hand a relative movement (in 1 in the vertical direction) between the cutting device 12 and clamping device 10 caused by a stroke of about 40-50 mm.

Wie in 2 zu erkennen ist, ist im Bereich der Klemmeinrichtung 10 für die Klemmelemente 12 und 14 jeweils ein Schlitten 48 und 50 vorgesehen, wobei jeder Schlitten von einem Elektromagneten gegen die Kraft einer Feder in entgegengesetzte Richtungen verstellbar ist. Hierdurch können auf bekannte Weise die frisch geschnittenen Stirnflächen der Schlauchenden A und B einander fluchtend gegenüber angeordnet werden, woraufhin anschließend ein Verschweißen dieser Schlauchenden mit Hilfe des Me tallbandes erfolgen kann. Bei diesem Schweißvorgang werden die beiden Schlauchenden A und B um eine geringe Strecke aufeinander zu bewegt, um mit dem Schmelzmaterial einen Wulst zur besseren Anhäufung von Material zur Verschweißung zu erreichen.As in 2 can be seen, is in the area of the clamping device 10 for the clamping elements 12 and 14 one sleigh each 48 and 50 provided, wherein each carriage is adjustable by an electromagnet against the force of a spring in opposite directions. As a result, the freshly cut end faces of the tube ends A and B can be arranged in alignment with each other in a known manner, whereupon then a welding of these tube ends can be done by means of Me tallbandes. In this welding operation, the two tube ends A and B are moved towards each other by a small distance to achieve a bead with the melt material for better accumulation of material for welding.

Zum sterilen Verbinden zweier Schlauchenden aus thermoplastischem Material werden die beiden Schlauchenden aus entgegengesetzten Richtungen in die Klemmeinrichtung 10 eingeführt und dort festgeklemmt. Anschließend wird die Klemmeinrichtung 10 relativ zu der Schneideinrichtung 12 so bewegt, dass das gespannte Metallband 20 in den Zwischenraum der Klemmeinrichtung 10 eingeführt wird. Da das Metallband 20 zuvor mit Hilfe der Elektroden 36 und 38 in dem dazwischen liegenden Abschnitt erhitzt worden ist, werden bei diesem Vorgang die Schlauchenden steril durchtrennt, so dass jedes Schlauchende einen frisch geschnittenen Endabschnitt aufweist. Anschließend werden die in 2 erkennbaren Elektromagnete betätigt, so dass sich in 2 das obere Klemmelement 12 nach links und das untere Klemmelement 14 nach rechts bewegt, bis die Schlauchenden A und B einander fluchtend gegenüberliegen. Die beiden Schlauchenden werden anschließend in Richtung des erhitzten Metallbandes 20 angestellt (vgl. hierzu auch die Doppelpfeile in 2), so dass hierdurch die frisch geschnittenen Schlauchenden miteinander verschweißt werden, woraufhin das Metallband 20 aus der Klemmeinrichtung 10 in vertikaler Richtung entfernt wird. Nach einer kurzen Abkühlzeit können die beiden miteinander verschweißten Schlauchenden A und B aus der Klemmeinrichtung entfernt werden, wobei es gegebenenfalls noch erforderlich sein kann, durch leichtes Zusammendrücken der Schweißstelle die vollständige Rohrform wieder herzustellen.For the sterile connection of two tube ends made of thermoplastic material, the two tube ends from opposite directions in the clamping device 10 introduced and clamped there. Subsequently, the clamping device 10 relative to the cutter 12 so moved that the strained metal band 20 in the intermediate space of the clamping device 10 is introduced. Because the metal band 20 previously with the help of the electrodes 36 and 38 has been heated in the intermediate section, the tube ends are sterile severed in this process, so that each end of the tube has a freshly cut end portion. Subsequently, the in 2 detectable electromagnets actuated, so that in 2 the upper clamping element 12 to the left and the lower clamping element 14 moved to the right until the tube ends A and B face each other in alignment. The two hose ends are then in the direction of the heated metal strip 20 employed (see also the double arrows in 2 ), so that thereby the freshly cut hose ends are welded together, whereupon the metal strip 20 from the clamping device 10 is removed in the vertical direction. After a short cooling time, the two welded together hose ends A and B can be removed from the clamping device, wherein it may still be necessary to restore the complete pipe shape by slightly squeezing the weld.
