Ausführungsform der ErfindungEmbodiment of the invention

Nachfolgend wird unter Bezugnahme auf die Figuren 1 und 2 eine Schlauchpumpe gemäß einem Beispiel im Detail beschrieben.The following is with reference to the Figures 1 and 2 a hose pump according to an example described in detail.

Wie aus der vergrößerten perspektivischen Ansicht eines Beispiels der Schlauchpumpe 1 von Figur 1 ersichtlich, umfasst die Schlauchpumpe ein zylindrisches Gehäuse 2 mit einem Grundkörper 2b und einem Deckel 2a zum Öffnen des Gehäuses.As is apparent from the enlarged perspective view of an example of the peristaltic pump 1 of FIG FIG. 1 As can be seen, the peristaltic pump comprises a cylindrical housing 2 with a base body 2b and a lid 2a for opening the housing.

Zum Ent- bzw. Verriegeln des Deckels 2a, der um eine erste Achse A schwenkbar ist, ist eine Verriegelungsvorrichtung 5 am Gehäuse 2 angeordnet. Die Verriegelungsvorrichtung 5, die in Figur 1 in verriegelter Stellung und in Figur 2 in entriegelter Stellung zu sehen ist, ist relativ zum Grundkörper 2b des Gehäuses 2 beweglich und am Grundkörper 2b unverlierbar befestigt. Die Verriegelungsvorrichtung 5 weist einen um eine zweite Achse B schwenkbaren Hebel 5a auf, der bei dem in Figur 1 dargestellten geschlossenen Zustand der Schlauchpumpe parallel zu einer dritten Achse C in Längsrichtung des Gehäuses 2 verläuft, gebogen ausgebildet ist und in Bezug auf das Gehäuse 2 einen nach außen gekröpften Endbereich 5b umfasst. Durch diese Formgebung des Hebels 5a wird das Ergreifen und Betätigen der Verriegelungsvorrichtung 5, insbesondere durch den bei Isolatorabfüllmaschinen erforderlichen Handschuheingriff, außerordentlich erleichtert und ist mit einer Hand ausführbar.For unlocking or locking the lid 2 a, which is pivotable about a first axis A, a locking device 5 is arranged on the housing 2. The locking device 5, which in FIG. 1 in locked position and in FIG. 2 can be seen in the unlocked position, relative to the base body 2b of the housing 2 is movable and captively secured to the base body 2b. The locking device 5 has a pivotable about a second axis B lever 5a, which in the in FIG. 1 illustrated closed state of the peristaltic pump parallel to a third axis C extends in the longitudinal direction of the housing 2, is formed bent and with respect to the housing 2 comprises an outwardly cranked end portion 5b. By this shape of the lever 5a, the gripping and pressing the locking device 5, in particular by the required in Isolatorabfüllmaschinen glove engagement, greatly facilitated and can be performed with one hand.

Gleichermaßen ist der Deckel 2a, wie aus Figur 2 ersichtlich, relativ zum Grundkörper 2b des Gehäuses 2 beweglich sowie am Grundkörper 2b unverlierbar befestigt und kann somit einhändig um die erste Achse A geschwenkt werden.Likewise, the lid 2a is as shown FIG. 2 can be seen, relative to the base body 2b of the housing 2 movable and captively secured to the base body 2b and thus can be pivoted about the first axis A with one hand.

Wie aus der perspektivischen Darstellung der in Figur 2 im geöffneten Zustand gezeigten Schlauchpumpe ersichtlich, ist im Inneren des Grundkörpers 2b des Gehäuses 2 ferner ein um die dritte Achse C drehbarer Pumpenkörper 3 zum Fördern einer Flüssigkeit angeordnet. Dieser Pumpenkörper 3 weist eine Vielzahl von am seinem Umfang angeordneten Rollen 4 auf, auf die ein Schlauch 6 ohne eine erforderliche Fixierung aufgelegt wird. Wenn der um die erste Achse A schwenkbar befestigte Deckel 2a geschlossen und durch Schwenken der Verriegelungsvorrichtung 5 in Richtung eines Pfeils P verriegelt wird, drückt die Innenoberfläche 7 des Deckels 2a den Schlauch 6 auf die Rollen 4. Bei rotierendem Pumpenkörper 3 klemmen die umlaufenden Rollen 4 somit den Schlauch 6 abschnittsweise ab und fördern dadurch die Flüssigkeit. Beim Entriegeln des Deckels 2a durch Schwenken der Verriegelungsvorrichtung 5 entgegen der Richtung des Pfeils P wird der Deckel 2a durch den noch vorhandenen Flüssigkeitsdruck im Schlauch 6 nach außen gedrückt und kann im günstigsten Fall vollständig um die erste Achse A nach außen bis zu einer Position schwenken, wie sie in Figur 2 dargestellt ist. Aufgrund des am Grundkörper 2b unverlierbar befestigten Deckels 2a und der am Grundkörper 2b unverlierbar befestigten Verriegelungsvorrichtung 5 weist die erfindungsgemäße Schlauchpumpe vorteilhafterweise keine losen Bauteile auf, die im Inneren des Isolators herabfallen können. Vorzugsweise ist die zweite Achse B zum Schwenken der Verriegelungsvorrichtung 5 senkrecht zur dritten Achse C der Schlauchpumpe angeordnet und die erste Achse A zum Schwenken des Deckels 2a wiederum senkrecht zur zweiten Achse B der Verriegelungsvorrichtung 5 angeordnet, um einen kompakten und leicht montierbaren Aufbau der Schlauchpumpe zu erreichen.As seen from the perspective view of FIG. 2 In the open state shown hose pump can be seen, in the interior of the main body 2b of the housing 2 also arranged around the third axis C rotatable pump body 3 for conveying a liquid. This pump body 3 has a plurality of rollers 4 arranged on its circumference, onto which a hose 6 is placed without a required fixation. When the lid 2a pivotally mounted about the first axis A is closed and locked by pivoting the locking device 5 in the direction of an arrow P, the inner surface 7 of the lid 2a pushes the tube 6 onto the rollers 4. With the pump body 3 rotating, the circulating rollers 4 are clamped thus the hose 6 in sections and thereby promote the liquid. When unlocking the lid 2a by pivoting the locking device 5 against the direction of the arrow P, the lid 2a is pushed by the remaining fluid pressure in the tube 6 to the outside and can pivot in the best case completely around the first axis A to the outside to a position as they are in FIG. 2 is shown. Because of the base body 2b captively fastened lid 2a and 2b on the base body captively fastened locking device 5, the hose pump according to the invention advantageously no loose components that can fall down inside the insulator. Preferably, the second axis B is arranged for pivoting the locking device 5 perpendicular to the third axis C of the peristaltic pump and the first axis A for pivoting the lid 2a in turn perpendicular to the second axis B of the locking device 5 arranged to a compact and easy to assemble construction of the peristaltic pump to reach.

In den Figuren 3 und 4 wird nun im Folgenden eine Schlauchpumpe 1 gemäß einem Ausführungsbeispiel der vorliegenden Erfindung beschrieben. Gleiche bzw. funktional gleiche Bauteile sind hier mit denselben Bezugszeichen wie im obigen Beispiel beschrieben.In the Figures 3 and 4 Now, a hose pump 1 according to an embodiment of the present invention will be described below. The same or functionally identical components are described here with the same reference numerals as in the above example.

Figur 3 zeigt die Schlauchpumpe 1 gemäß dem Ausführungsbeispiel in vergrößerter perspektivischer Darstellung im geöffneten Zustand. Im Gegensatz zum in den Figuren 1 und 2 gezeigten Beispiel weist das Ausführungsbeispiel zwei koaxial angeordnete Pumpenkörper 3, 3a im Grundkörper 2b auf. Die Zuführung der Flüssigkeit zu den zwei Pumpenkörpern 3, 3a erfolgt über einen in Figur 4 dargestellten Abzweigschlauch 10, der einen zweifachen Schlauchabschnitt 11 aufweist. Wie in Figur 4 dargestellt, verzweigt sich der zweifache Schlauchabschnitt 11 jeweils an Verzweigungen 14 und 15 vom einfachen Abschnitt des Schlauchs 6, so dass in beiden Zweigen des zweifachen Schlauchabschnitts 11 beim Betrieb der Schlauchpumpe identische Volumenströme gefördert werden. FIG. 3 shows the hose pump 1 according to the embodiment in an enlarged perspective view in the open state. Unlike in the Figures 1 and 2 As shown, the exemplary embodiment has two coaxially arranged pump bodies 3, 3a in the main body 2b. The supply of the liquid to the two pump bodies 3, 3a via a in FIG. 4 illustrated branch hose 10, which has a double tube section 11. As in FIG. 4 shown, the two-fold hose section 11 branches at branches 14 and 15 from the simple portion of the hose 6, so that in both branches of the double hose section 11 identical volume flows are promoted during operation of the peristaltic pump.

An der Außenseite des Grundkörpers 2b des Gehäuses 2 sind, wie in Figur 3 ersichtlich, zwei vom Grundkörper 2b vorstehende Stifte 9 angeordnet. An einem dieser Stifte 9 wird der Schlauch 6 an seiner ersten Verzweigung 14 eingehängt und danach wird der zweifache Schlauchabschnitt 11 über die Pumpenkörper 3, 3a gezogen und der Schlauch 6 an seiner zweiten Verzweigung 15 am anderen Stift 9 eingehängt bzw. eingespannt. Dieser Vorgang ist mit dem verwendeten Handschuh, ebenso wie beim einfachen Schlauch des obigen Beispiels, auf einfache Weise einhändig durchführbar und weist folglich einen deutlichen Vorteil gegenüber der Schlauchmontage bei den derzeit verwendeten herkömmlichen Schlauchpumpen in einem Isolator auf, die im Handschuheingriff mit beiden Händen erfolgen muss. Ansonsten entspricht dieses Ausführungsbeispiel dem obigen Beispiel, sodass auf die dort gegebene Beschreibung verwiesen werden kann.On the outside of the main body 2b of the housing 2, as in FIG. 3 can be seen, arranged two protruding from the base 2b pins 9. At one of these pins 9, the tube 6 is hooked at its first branch 14 and then the double tube section 11 is pulled over the pump body 3, 3a and the tube 6 is suspended or clamped at its second branch 15 at the other pin 9. This operation is easily practicable with the glove used, as in the simple tube of the above example, and thus has a clear advantage over the hose assembly in the currently used conventional peristaltic pumps in an insulator, which must be done in glove engagement with both hands , Otherwise, this embodiment corresponds to the above example, so that reference can be made to the description given there.
