- Optimum ventilation of the tube segment 12 also results in the liquid guide shown here. Air which rises in the inlet region of the tube 12 rises upward by the buoyancy force and is forcibly guided along the tube 12 within the rise by the pressure rollers of the rotor. As far as they arrive at the end region of the hose 12 (seen in the direction of arrow A), the entrained air is also in the ascending region of the hose 12, so that they continue to rise and be discharged through the hose 18.

- the ejection of the adapter via a pin 54 (see. Fig. 2 ).
- the pin is executed near the round clip receptacle 28, so that the adapter 34 is first separated from the housing on the round contact side when the pin 54 is correspondingly actuated.
- the corresponding pin 54 can be moved controlled in a manner not shown here by the pump-side housing, so that the round side 42 of the adapter 32 snaps from the clip recording.
- the tilting movement created by the arrangement of the pin 54 when ejecting the adapter has another advantage.
- the roller pump 10 is equipped with two radial pins, as for example in the US 4,545,544 A is described.
- the two pins are mounted on opposite sides.
- the left side of the adapter 34 is raised and the right side of the adapter 34 is not raised, the lower pin can easily drive clockwise under the hose to lift it while the upper pin can easily pass over the still inserted hose.
- a pin can get caught in the pump hose system. This is prevented by the tilting movement when ejecting the adapter 32.
- the adapter 32 is designed such that it allows an edge-free connection between the pump hose segment 12 and the outer hose segments 16, 18, which, for example in the Fig. 1 can be seen to have different inner diameters.

This allows the invention a possible good and level alignment of the entire pump loop, so there is no excessive abrasion through the hose guide pins.
- the pin 54 can also serve as a sensor for a provided on the adapter 32 nubs.
- the pin 54 is moved vertically in a manner not shown by pressing the nubs, which can be detected by a light barrier also not shown here.

Derartige Rollenpumpen sind beispielsweise aus der
Aufgabe der Erfindung ist es, die gattungsgemäße Rollenpumpe derart weiterzubilden, daß flüssigkeitsführende Schläuche in besonders platzsparender Art und Weise einsetzbar sind.The object of the invention is to develop the generic roller pump such that fluid-carrying hoses can be used in a particularly space-saving manner.
Erfindungsgemäß wird diese Aufgabe durch eine Rollenpumpe mit den Merkmalen des Anspruchs 1 gelöst. Des weiteren betrifft die Erfindung ein Anschlußstück mit den Merkmalen des Anspruchs 13 und/oder 14, ein Schlauchset mit den Merkmalen des Anspruchs 15 und/oder 16 sowie ein Verfahren zum Betreiben einer Rollenpumpe mit den Merkmalen des Anspruchs 17.According to the invention this object is achieved by a roller pump with the features of claim 1. Furthermore, the invention relates to a fitting with the features of
Erfindungsgemäß besteht eine Rollenpumpe aus einem Stator mit einem in diesem ausgeformten Pumpenbett und einem Rotor zur Beaufschlagung eines bogenförmig in das Pumpenbett eingelegten Schlauches, wobei sich die aus dem Pumpenbett herausgeführten Enden des Schlauches unmittelbar nach Austritt aus dem Pumpenbett kreuzen. Es ergibt sich somit ein Pumpensegment in Form eines griechischen Alpha. Aufgrund dieser Formgebung können die Schläuche unmittelbar unterhalb bzw. neben der Rollenpumpe platzsparend weitergeführt werden, ohne daß die Gefahr des Abknickens besteht.According to the invention, a roller pump consists of a stator having a pump bed formed therein and a rotor for impinging a tube inserted into the pump bed in an arc, the ends of the tube leading out of the pump bed crossing each other immediately after exiting the pump bed. This results in a pump segment in the form of a Greek alpha. Due to this design, the hoses can be continued directly below or next to the roller pump to save space, without the risk of kinking exists.
Weitere besonders bevorzugte Ausführungsvarianten der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen.Further particularly preferred embodiments of the invention will become apparent from the subsequent claims to the main claim.
Erfindungsgemäß ist der Schlauch durch ein Anschlußstück in der Rollenpumpe fixierbar sein. Der in die Rollenpumpe eingelegte Schlauch kann durch das Anschlußstück führbar sein und somit als einstückiger Schlauch ausgebildet sein. Alternativ kann aber auch in dem Anschlußstück ein getrenntes in das Pumpenbett einlegbares Schlauchstück sowie das zuführende bzw. wegführende Schlauchstück angeschlossen sein.According to the invention the hose can be fixed by a connecting piece in the roller pump. The inserted into the roller pump hose can be feasible through the connector and thus formed as a one-piece hose. Alternatively, however, a separate piece of tubing which can be inserted into the pump bed as well as the feeding or leading hose section can also be connected in the connecting piece.
Das Anschlußstück kann vorteilhaft als Adapter ausgebildet sein, wobei der Adapter aufgrund seiner Form in entsprechend Aufnahmeausnehmungen in der Rollenpumpe einsetzbar ist. Durch diesen jeweiligen Formschluss kann eine Codierung realisiert werden, die noch durch eine entsprechende Farbgebung unterstützt werden kann. Die Aufnahmeausnehmungen des Adapters greifen seitlich in zwei Clipsaufnahmen, vorzugsweise unterschiedlicher Form. An die entsprechende Formgebung der Clipse ist der einclipsbare Adapter angepasst.The connecting piece can be advantageously designed as an adapter, wherein the adapter can be used due to its shape in accordance with receiving recesses in the roller pump. By this respective form-fitting coding can be realized, which can be supported by a corresponding color. The receiving recesses of the adapter engage laterally in two clip receptacles, preferably of different shape. The clip-in adapter is adapted to the shape of the clips.
Gemäß einer anderen vorteilhaften Ausgestaltung der Erfindung ist am Adapter eine Einrichtung, vorzugsweise ein Noppen, angeordnet, die mit einem in der Rollenpumpe bzw. in dem die Rollenpumpe bildenden Gehäuse integrierten Sensor zusammenwirkt. Der Sensor bestätigt das funktionsgerechte Einsetzen des Adapters an der entsprechenden Stelle.According to another advantageous embodiment of the invention, a device, preferably a knob, is arranged on the adapter, which cooperates with a sensor integrated in the roller pump or in the housing forming the roller pump. The sensor confirms the functional insertion of the adapter in the appropriate place.
Besonders vorteilhaft besteht der Adapter aus einem weichen Kunststoff, vorzugsweise Weich-PVC.Particularly advantageously, the adapter consists of a soft plastic, preferably soft PVC.
Die Vorteile der erfindungsgemäßen Schlauchführung ergeben sich erfindungsgemäß, wenn das Anschlußstück bei waagerechter Ausrichtung der Rotorachse seitlich am Pumpenbett angeordnet ist. Durch diese Anordnung kann in Zusammenwirkung mit einer entsprechenden Drehrichtung des Rotors eine optimale Entlüftung des Schlauchsegments erreicht werden. Es wird nämlich sichergestellt, daß Luft, die im Eingangsbereich liegt, durch die Auftriebskraft nach oben steigt. Noch innerhalb des Anstiegs greifen die entsprechenden Andruckrollen des Rotors in das im Pumpenbett liegende Schlauchsegment ein und garantieren eine Zwangsförderung der entsprechenden Luftblasen. Am Ausgang des Schlauchsegments ist es ähnlich. Wenn die Andruckrollen das Schlauchsegment wieder freigeben, befindet sich die mitgeführte Luft bereits im aufsteigenden Bereich des Schlauchsegments. Hierdurch gibt es keine die Luft in die Pumpe zurücktreibende Kraft. Diese Vorteile sind weder bei einer U-förmigen Anordnung noch bei einer Ω-förmigen Anordnung des Schlauchsegments im Pumpenbett, wie sie im Stand der Technik bekannt waren, erzielbar.The advantages of the hose guide according to the invention will become apparent according to the invention, when the connector is arranged laterally on the pump bed with horizontal alignment of the rotor axis. By this arrangement, in conjunction with a corresponding direction of rotation of the rotor optimum ventilation of the tube segment can be achieved. It is namely ensured that air, which is located in the entrance area, rises by the buoyancy force upwards. Even within the rise, the corresponding pinch rollers of the rotor engage in the hose segment lying in the pump bed and guarantee a forced conveyance of the corresponding air bubbles. It is similar at the exit of the hose segment. When the pinch rollers release the hose segment, the entrained air is already in the rising area of the hose segment. As a result, there is no force driving the air back into the pump. These advantages are neither in a U-shaped arrangement still in a Ω-shaped arrangement of Hose segment in the pump bed, as they were known in the art, achievable.
Um die optimale Entlüftung zu erreichen, weist die Rollenpumpe erfindungsgemäß eine Steuereinheit auf, die die entsprechende Drehrichtung des Rotors in Abhängigkeit von der seitlichen Ausrichtung des Anschlußstückes vorgibt. So wird der Rotor gegen Uhrzeigerrichtung gedreht, wenn sich die Schläuche auf der rechten Seite kreuzen, und in Uhrzeigerrichtung, wenn sich die Schläuche auf der linken Seite kreuzen.In order to achieve the optimum ventilation, the roller pump according to the invention has a control unit which determines the corresponding direction of rotation of the rotor in dependence on the lateral orientation of the connecting piece. Thus, the rotor is rotated counterclockwise when the hoses cross on the right side and clockwise when the hoses cross on the left side.
Der in die Rollenpumpe einlegbare Schlauch kann auch an ein Anschlußstück angeschlossen sein, das als integrierte Kassette ausgebildet ist. Schließlich betrifft die Erfindung auch ein Schlauchset mit einem Anschlußstück, wie es zuvor beschrieben wurde, sowie einem in das Pumpenbett einzulegenden und mit dem Anschlußstück verbundenen Schlauch.The insertable into the roller pump hose can also be connected to a connector, which is designed as an integrated cassette. Finally, the invention also relates to a hose set with a connecting piece, as described above, as well as a tube to be inserted into the pump bed and connected to the connecting piece.
Die Erfindung betrifft auch ein Anschlußstück, das in eine erfindungsgemäße Rollenpumpe einsetzbar ist.The invention also relates to a connecting piece which can be used in a roller pump according to the invention.
Weitere Merkmale, Einzelheiten und Vorteile der Erfindung ergeben sich aus den in der Zeichnung dargestellten Ausführungsbeispielen.Further features, details and advantages of the invention will become apparent from the embodiments illustrated in the drawings.

Bei der hier dargestellten Flüssigkeitsführung ergibt sich ebenfalls eine optimale Entlüftung des Schlauchsegments 12. Luft die im Eingangsbereich des Schlauchs 12 liegt, steigt durch die Auftriebskraft nach oben, wird innerhalb des Anstiegs durch die Andruckrollen des Rotors entlang des Schlauchs 12 zwangsgeführt. Soweit sie am Endbereich des Schlauchs 12 (in Pfeilrichtung A gesehen) ankommen, befindet sich die mitgeführte Luft ebenfalls im aufsteigenden Bereich des Schlauchs 12, so daß sie weiter aufsteigen und durch den Schlauch 18 ausgetragen werden. Diese vorteilhafte Entlüftung ergibt sich, wenn der sich kreuzende Teil des Schlauches auf der rechten Seite angeordnet ist und sich der Rotor 11 gleichzeitig gegen den Uhrzeigersinn dreht. Alternativ ergibt sich die vorteilhafte Entlüftung für den Fall, daß der sich kreuzende Teil des Schlauches auf der linken Seite ist, wenn sich der Rotor im Uhrzeigersinn dreht.Optimum ventilation of the
