Description

Die Erfindung betrifft eine Austragvorrichtung für eine fliessfähige Komponente gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a discharge device for a flowable component according to the preamble of claim 1.

Siehe als nächstliegender Stand der Technik DE 102010060671 .See as closest prior art DE 102010060671 ,

In der EP 1 968 751 B1 wird eine Austrageinrichtung für zwei fliessfähige Komponenten beschrieben. Die Austrageinrichtung verfügt über einen Vorratsbehälter mit einer ersten Vorratskammer für eine erste Komponente und einem ersten Komponentenauslass und ein mit dem Vorratsbehälter verbundenes Austragelement, welches eine Austragöffnung aufweist. Der Vorratsbehälter weist ausserdem eine zweite Vorratskammer für eine zweite Komponente und einem zweiten Komponentenauslass auf. Die Austragsvorrichtung ist als ein statischer Mischer ausgeführt, in dem die beiden Komponenten vor dem Verlassen des Mischers gemischt werden. Der Vorratsbehälter weist einen den Komponentenauslass umfassenden Auslassflansch mit einer zylinderförmigen Mantelfläche auf. Der Auslassflansch wird von einem Einlassflansch des Austragselements zumindest teilweise umschlossen, wobei der Einlassflansch gegenüber dem Auslassflansch verdrehbar angeordnet ist. Der Einlassflansch kann gegenüber dem Auslassflansch eine Schliessposition und eine Austragposition einnehmen. In der Schliessposition sind die Komponentenauslässe verschlossen und in der Austragposition ist ein Austrag der beiden Komponenten über die beiden Komponentenauslässe und die Austragöffnung möglich. Ein Wechsel von der Schliessposition in die Austragposition wird durch eine Verdrehung des Einlassflanschs gegenüber dem Auslassflansch durchgeführt.In the EP 1 968 751 B1 a discharge device for two flowable components is described. The discharge device has a storage container with a first storage chamber for a first component and a first component outlet and a discharge element connected to the storage container, which has a discharge opening. The storage container also has a second storage chamber for a second component and a second component outlet. The discharge device is designed as a static mixer in which the two components are mixed before leaving the mixer. The storage container has an outlet flange which comprises the component outlet and has a cylindrical lateral surface. The outlet flange is at least partially enclosed by an inlet flange of the discharge element, wherein the inlet flange is arranged rotatable relative to the outlet flange. The inlet flange may assume a closing position and a discharge position relative to the outlet flange. In the closed position, the component outlets are closed and in the discharge position a discharge of the two components via the two component outlets and the discharge opening is possible. A change from the closed position to the discharge position is carried out by a rotation of the inlet flange relative to the outlet flange.

Die Komponentenauslässe sind in Richtung Austragöffnung orientiert und werden in der Schliessposition des Einlassflanschs durch flexible, mit dem Einlassflansch verbundene Verschlussstopfen verschlossen. Beim Verdrehen des Einlassflanschs von der Schliessposition in die Austragposition werden die Verschlussstopfen aus den Austragöffnungen herausgezogen und dabei stark verformt oder verbogen.The component outlets are oriented in the direction of the discharge opening and are closed in the closed position of the inlet flange by flexible sealing plugs connected to the inlet flange. When turning the inlet flange from the closed position to the discharge position the plugs pulled out of the discharge and thereby greatly deformed or bent.

Demgegenüber ist es die Aufgabe der Erfindung, eine Austragvorrichtung vorzuschlagen, welche einfach und kostengünstig herstellbar ist. Erfindungsgemäß wird diese Aufgabe mit einer Austragvorrichtung mit den Merkmalen des Anspruchs 1 gelöst.In contrast, it is the object of the invention to provide a discharge, which is simple and inexpensive to produce. According to the invention this object is achieved with a discharge device having the features of claim 1.

Erfindungsgemäss ist der erste Komponentenauslass an der zylinderförmigen Mantelfläche des Auslassflanschs angeordnet. In der Schliessposition des Einlassflanschs ist der erste Komponentenauslass durch den Einlassflansch verschlossen. Der Einlassflansch dichtet damit in dieser Position den ersten Komponentenauslass ab. Der Einlassflansch weist dazu insbesondere einen ersten Abschnitt mit einer Innenkontur auf, die mit der Mantelfläche des Auslassflanschs so korrespondiert, dass in dem Fall, in dem der erste Abschnitt über dem ersten Komponentenauslass angeordnet ist, die erste Komponente nicht aus dem ersten Komponentenauslass austreten kann und damit der erste Komponentenauslass verschlossen ist.According to the invention, the first component outlet is arranged on the cylindrical jacket surface of the outlet flange. In the closing position of the inlet flange of the first component outlet is closed by the inlet flange. The inlet flange thus seals the first component outlet in this position. For this purpose, in particular, the inlet flange has a first section with an inner contour which corresponds to the lateral surface of the outlet flange such that, in the case where the first section is arranged above the first component outlet, the first component can not escape from the first component outlet and so that the first component outlet is closed.

Der Einlassflansch weist ausserdem einen ersten Überströmkanal auf. Der erste Überströmkanal, ist so ausgeführt und angeordnet, dass er in der Austragposition des Einlassflanschs eine Verbindung zwischen dem ersten Komponentenauslass und der Austragsöffnung herstellt. Der Einlassflansch weist dazu insbesondere einen zweiten Abschnitt mit einer Innenkontur auf, die so ausgeführt ist, dass in dem Fall, in dem der zweite Abschnitt über dem ersten Komponentenauslass angeordnet ist, sich ein Zwischenraum zwischen dem ersten Komponentenauslass und dem Eintrittsflansch ergibt, welcher den Überströmkanal bildet. Der genannte Zwischenraum ist mit dem Austragelement und damit mit der Austragöffnung verbunden, so dass die beim Austragen aus dem ersten Komponentenauslass austretende erste Komponente über den einen Teil des Überströmkanals bildenden Zwischenraum zum Austragelement und damit zur Austragöffnung gelangen kann.The inlet flange also has a first overflow channel. The first transfer passage is designed and arranged such that it establishes a connection between the first component outlet and the discharge opening in the discharge position of the inlet flange. For this purpose, the inlet flange has in particular a second section with an inner contour, which is designed so that in the case in which the second section is arranged above the first component outlet, there is a gap between the first component outlet and the inlet flange, which forms the overflow channel forms. Said intermediate space is connected to the discharge element and thus to the discharge opening, so that the first component exiting from the first component outlet during discharge can pass via the intermediate space forming a part of the transfer channel to the discharge element and thus to the discharge opening.

Bei der erfindungsgemässen Austragvorrichtung ist kein flexibler Verschlussstopfen zum Verschliessen des ersten Komponentenauslasses notwendig. Derartige Verschlussstopfen sind nur aufwendig und damit teuer herstellbar.In the discharge device according to the invention, no flexible sealing plug is necessary for closing the first component outlet. Such plugs are only expensive and thus expensive to produce.

Ausserdem kann die erfindungsgemässe Austragvorrichtung besonders einfach gefüllt werden, ohne dass Luft eingeschlossen wird. Beim Füllen der Vorratskammer kann der Einlassflansch in die Austragposition gebracht werden. Damit kann Luft, die beim Einfüllen der ersten Komponente eingeschlossen wird, über die Austragöffnung entweichen. Sobald die Befüllung abgeschlossen ist, kann der Einlassflansch in die Schliessposition gebracht und damit die erste Vorratskammer abgeschlossen werden.In addition, the discharge device according to the invention can be filled particularly easily without air being trapped. When filling the storage chamber, the inlet flange can be brought into the discharge position. Thus, air that is trapped in the filling of the first component, escape through the discharge opening. Once the filling is completed, the inlet flange can be brought into the closed position and thus the first pantry can be completed.

Darüber hinaus weist die Austragvorrichtung nur ein besonders geringes Verlustvolumen auf. Unter dem Verlustvolumen ist die Menge der ersten Komponente zu verstehen, die nicht aus der Austragvorrichtung ausgebracht werden kann und damit ungenutzt in der Austragvorrichtung verbleibt. Das gesamte Volumen eines Verschlussstopfens ist Teil des Verlustvolumens. Da bei der erfindungsgemässen Austragvorrichtung kein Verschlussstopfen notwendig ist, ist das Verlustvolumen entsprechend kleiner.In addition, the discharge device only has a particularly low loss volume. The loss volume is to be understood as the amount of the first component which can not be discharged from the discharge device and therefore remains unused in the discharge device. The entire volume of a stopper is part of the loss volume. Since in the inventive discharge no sealing plug is necessary, the loss volume is correspondingly smaller.

Der Auslassflansch kann so ausgeführt sein, dass er über seine gesamte axiale Erstreckung nur eine durchgängige zylinderförmige Mantelfläche mit einem konstanten Durchmesser aufweist. Es ist aber auch möglich, dass der Auslassflansch mehrere zylindrische Mantelflächen mit unterschiedlichen Durchmessern oder auch nur einen Abschnitt mit einer zylindrischen Mantelfläche aufweist, an der der erste Komponentenauslass angeordnet ist.The outlet flange may be designed so that it has only a continuous cylindrical circumferential surface with a constant diameter over its entire axial extent. But it is also possible that the outlet flange has a plurality of cylindrical lateral surfaces with different diameters or even only a portion with a cylindrical lateral surface on which the first component outlet is arranged.

Das Austragelement kann insbesondere als ein gerades oder gebogenes Röhrchen ausgeführt sein, dessen offenes, dem Einlassflansch gegenüber liegendes Ende die Austragöffnung bildet. Der Einlassflansch und das Austragelement sind insbesondere als ein Bauteil ausgeführt, das mittels eines Spritzgussverfahrens hergestellt wird.The discharge element may in particular be designed as a straight or bent tube whose open, the inlet flange opposite end forms the discharge opening. The inlet flange and the discharge element are in particular designed as a component which is produced by means of an injection molding process.

Der Vorratsbehälter und der Auslassflansch sind insbesondere als ein Bauteil, beispielsweise aus Kunststoff ausgeführt, das mittels einesThe reservoir and the outlet flange are in particular designed as a component, for example made of plastic, by means of a

Spritzgussverfahrens hergestellt wird. Die erste Vorratskammer weist insbesondere eine hohlzylindrische Innenkontur auf, in der ein erster Kolben angeordnet ist, der zum Austragen der ersten Komponente in Richtung erstem Komponentenauslass und damit in Richtung einer Austragrichtung verschiebbar ist. Der erste Kolben kann beispielsweise über eine Betätigungsstange von Hand verschoben werden. In diesem Fall ist die Austragvorrichtung ist als eine Spritze ausgeführt. Es ist aber auch möglich, dass die Austragvorrichtung als eine so genannte Kartusche ausgeführt ist, die zum Verschieben des ersten Kolbens in ein Austraggerät eingesetzt wird. Es ist ebenfalls möglich, dass die Vorratskammer als ein so genannter Schlauchbeutel ausgeführt ist, der zum Austragen der ersten Komponente zusammengedrückt oder aufgerollt wird.Injection molding is produced. The first storage chamber has in particular a hollow cylindrical inner contour in which a first piston is arranged, which is displaceable for discharging the first component in the direction of the first component outlet and thus in the direction of a discharge direction. The first piston can be moved by hand, for example via an actuating rod. In this case, the discharge device is designed as a syringe. But it is also possible that the discharge device is designed as a so-called cartridge, which is used to move the first piston in a dispensing device. It is also possible that the storage chamber is designed as a so-called tubular bag which is compressed or rolled up to discharge the first component.

Zur Kennzeichnung der Schliessposition und der Austragposition des Einlassflanschs gegenüber dem Auslassflansch können entsprechende Markierungen an Einlassflansch und Auslassflansch oder Vorratsbehälter vorgesehen sein.To mark the closing position and the discharge position of the inlet flange relative to the outlet flange, corresponding markings may be provided on the inlet flange and outlet flange or reservoir.

Grundsätzlich ist es möglich, dass der Einlassflansch aus der Schliessposition heraus in beide Richtungen gegenüber dem Auslassflansch verdreht werden kann. Es ist aber auch möglich, dass nur eine Verdrehung in eine Richtung möglich ist. Ausserdem kann eine Rückdrehsicherung vorgesehen sein, so dass nach Einstellen der Austragposition eine Verdrehung in die Schliessposition nicht mehr möglich ist. Damit kann sichergestellt werden, dass die Austragvorrichtung nur ein einziges Mal verwendet werden kann.In principle, it is possible that the inlet flange can be rotated out of the closed position in both directions with respect to the outlet flange. But it is also possible that only one twist in one direction is possible. In addition, a reverse rotation can be provided so that after adjusting the discharge position, a rotation in the closed position is no longer possible. This can ensure that the discharge can be used only once.

Die erfindungsgemässe Austragvorrichtung ist beispielsweise im Dentalbereich oder für Klebstoffe eingesetzt werden.The inventive discharge device is used for example in the dental field or for adhesives.

In Ausgestaltung der Erfindung weist der Auslassflansch eine umlaufende Anschlagfläche auf, die in Richtung Austragöffnung, also in Austragrichtung ausgerichtet ist. Die Austragöffnung ist so ausgeführt, dass auch im gesamten Bereich des Überströmkanals eine Gegenfläche des Einlassflanschs an die Anschlagfläche anschlägt. Damit ist der Überströmkanal in der Austragposition des Einlassflanschs gegenüber dem Auslassflansch durch die Anschlagfläche entgegen der Austragrichtung abgegrenzt, womit ein Fliessen der ersten Komponente entgegen der Austragrichtung verhindert wird.In an embodiment of the invention, the outlet flange has a circumferential stop surface which is aligned in the direction of the discharge opening, that is to say in the discharge direction. The discharge opening is designed so that in the entire region of the overflow channel, a counter surface of the inlet flange to the Stop surface strikes. Thus, the overflow is delimited in the discharge position of the inlet flange relative to the Auslassflansch by the abutment surface against the discharge, whereby a flow of the first component against the discharge is prevented.

In Ausgestaltung der Erfindung weist der Auslassflansch einen umlaufenden Bund auf, der mit einer korrespondierenden Nut im Einlassflansch eine Rastverbindung zwischen dem Auslassflansch und dem Einlassflansch bildet. Damit ist eine besonders einfache und kostengünstige Verbindung zwischen dem Auslassflansch und dem Einlassflansch und damit zwischen Austragselement und Vorratsbehälter möglich.In an embodiment of the invention, the outlet flange has a circumferential collar which forms a latching connection between the outlet flange and the inlet flange with a corresponding groove in the inlet flange. This makes a particularly simple and cost-effective connection between the outlet flange and the inlet flange and thus possible between the discharge element and the storage container.

In Ausgestaltung der Erfindung begrenzt die Anschlagfläche den Bund in Richtung Austragöffnung, also in Austragrichtung. Damit ist es nicht oder nur unter Aufbringung einer sehr grossen Kraft möglich, das Austragselement zu weit auf den Vorratsbehälter aufzustecken. Somit kann ein korrektes Aufstecken des Austragselements auf den Vorratsbehälter und damit ein korrekter Zusammenbau der Austragsvorrichtung sichergestellt werden.In an embodiment of the invention, the stop surface limits the collar in the direction of the discharge opening, ie in the discharge direction. Thus, it is not possible or only with the application of a very large force, aufzustecken the discharge too far on the reservoir. Thus, a correct attachment of the Austragselements can be ensured on the reservoir and thus a correct assembly of the discharge.

In Ausgestaltung der Erfindung weist der Vorratsbehälter eine zweite Vorratskammer für eine zweite Komponente und einen zweiten Komponentenauslass auf, welcher ebenfalls an der Mantelfläche des Auslassflanschs angeordnet ist. In der Schliessposition des Einlassflanschs ist auch der zweite Komponentenauslass durch den Einlassflansch verschlossen. Der Einlassflansch weist einen zweiten Überströmkanal auf, der so ausgeführt und angeordnet ist, dass er in der Austragposition des Einlassflanschs eine Verbindung zwischen dem zweiten Komponentenauslass und dem Austragelement herstellt. Das Austragelement ist als ein Mischer mit einem Mischergehäuse und einem innerhalb des Mischergehäuses angeordneten Mischelement ausgeführt, wobei der Einlassflansch als ein Teil des Mischergehäuses ausgeführt ist.In an embodiment of the invention, the storage container has a second storage chamber for a second component and a second component outlet, which is likewise arranged on the lateral surface of the outlet flange. In the closed position of the inlet flange and the second component outlet is closed by the inlet flange. The inlet flange has a second overflow channel, which is designed and arranged such that it establishes a connection between the second component outlet and the discharge element in the discharge position of the inlet flange. The discharge element is designed as a mixer with a mixer housing and a mixing element arranged inside the mixer housing, wherein the inlet flange is designed as a part of the mixer housing.

Damit kann die Austragvorrichtung zum Austragen und Mischen zwei unterschiedlicher fliessfähiger Komponenten eingesetzt werden, die beispielsweise nach dem Mischen aushärten.Thus, the discharge can be used for discharging and mixing two different flowable components that cure, for example, after mixing.

Es ist auch möglich, dass der Vorratsbehälter eine dritte und ggf. weitere Vorratskammern aufweist und so drei oder mehr Komponenten ausgetragen und vermischt werden können.It is also possible for the storage container to have a third and optionally further storage chambers and so three or more components can be discharged and mixed.

Das Mischelement kann insbesondere einstückig mit dem Auslassflansch ausgeführt sein. Damit besteht die Austragvorrichtung aus besonders wenigen Einzelteilen, womit die Herstellung der Austragvorrichtung besonders kostengünstig ist.The mixing element may in particular be designed in one piece with the outlet flange. Thus, the discharge of particularly few items, making the production of the discharge is particularly cost.

In diesem Fall hat die Anordnung der Komponentenauslässe an der Mantelfläche des Auslassflanschs auch fertigungstechnische Vorteile bei der Herstellung mittels eines Spritzgussprozesses. Für die Bildung der Komponentenauslässe sind so genannte Kerne notwendig, die zum Abschluss eines Spritzgussvorgangs wieder herausgezogen werden müssen. Wären die Komponentenauslässe in Richtung Austragöffnung orientiert, so kann beim Abziehen der Kerne das ebenfalls in Richtung Austragöffnung orientierte Mischelement im Weg sein.In this case, the arrangement of the component outlets on the lateral surface of the outlet flange also manufacturing advantages in the production by means of an injection molding process. For the formation of the component outlets so-called cores are necessary, which must be pulled out again to complete an injection molding process. If the component outlets were oriented in the direction of the discharge opening, the mixing element, which is likewise oriented in the direction of the discharge opening, may be in the way when the cores are removed.

In Ausgestaltung der Erfindung sind der erste und der zweite Komponentenauslass in entgegen gesetzte Richtungen orientiert. Damit weisen eine erste Austrittsrichtung der ersten Komponente aus dem ersten Komponentenauslass und eine zweite Austrittsrichtung der zweiten Komponente aus dem zweiten Komponentenauslass entgegen gesetzte Richtungen auf und schliessen einen Winkel von 180° ein. Damit wird wirkungsvoll vermieden, dass es vor Erreichen des Mischelements zu einem Kontakt zwischen den beiden Komponenten, also zu einer so genannten Querkontamination kommt.In an embodiment of the invention, the first and the second component outlet are oriented in opposite directions. Thus, a first outlet direction of the first component from the first component outlet and a second outlet direction of the second component from the second component outlet have opposite directions and enclose an angle of 180 °. This effectively prevents the contact between the two components, that is to say cross-contamination, from reaching the mixing element.

Falls mehr als zwei Komponenten ausgetragen werden sollen, so sind die Komponentenauslässe insbesondere so orientiert, dass sich jeweils zwischen zwei benachbarten Austrittsrichtungen der selbe Winkel ergibt. Also bei drei Komponenten ein Winkel von 120° und bei vier Komponenten ein Winkel von 90°.If more than two components are to be discharged, the component outlets are oriented in particular such that the same angle results in each case between two adjacent exit directions. So with three components an angle of 120 ° and with four components an angle of 90 °.

Es sind aber auch andere Winkel zwischen benachbarten Austrittsrichtungen möglich.But there are also other angles between adjacent exit directions possible.

In Ausgestaltung der Erfindung ist bei entgegen gesetzter Orientierung der Komponentenauslässe für den Wechsel von der Schliessposition in die Austragposition eine Verdrehung des Einlassflanschs gegenüber dem Auslassflansch von 90° notwendig. Damit ergibt sich in der Schliessposition ein maximaler Abstand zwischen den Komponentenauslässen und den Überströmkanälen und somit eine maximale Dichtfläche für die Komponentenauslässe. Es kann damit in der Schliessposition des Einlassflanschs ein ungewolltes Austreten einer der beiden Komponenten wirkungsvoll vermieden werden.In an embodiment of the invention, in the opposite orientation of the component outlets for the change from the closed position to the discharge position, a rotation of the inlet flange relative to the outlet flange of 90 ° is necessary. This results in the closed position, a maximum distance between the component outlets and the overflow and thus a maximum sealing surface for the component outlets. It can thus be effectively avoided in the closed position of the inlet flange accidental leakage of one of the two components.

In Ausgestaltung der Erfindung ist der Mischer als ein statischer Mischer ausgeführt. Der Mischer weist damit ein feststehendes Mischelement auf. Der Mischer und damit die gesamte Austragvorrichtung sind damit besonders kostengünstig herstellbar. Der Auslassflansch und das Mischelement können dabei als ein einziges oder als getrennte Bauteile ausgeführt sein. Meist wird aus Kostengründen angestrebt, die Anzahl der einzelnen Bauteile einer Austragvorrichtung möglichst gering zu halten, womit Auslassflansch und Mischelement als ein Bauteil ausgeführt wären. Es kann aber in Einzelfällen auch sinnvoll sein, Auslassflansch und Mischelement als getrennte Bauteile auszuführen. Das kann beispielsweise dann der Fall sein, wenn das Mischelement sehr klein und empfindlich ausgeführt ist und bei der Herstellung der beiden Elemente als ein einziges Bauteil Beschädigungen des Mischelements auftreten könntenIn an embodiment of the invention, the mixer is designed as a static mixer. The mixer thus has a fixed mixing element. The mixer and thus the entire discharge are thus particularly inexpensive to produce. The outlet flange and the mixing element can be designed as a single or separate components. Usually, for reasons of cost, the aim is to keep the number of individual components of a discharge device as low as possible, whereby the outlet flange and mixing element would be designed as one component. However, in individual cases it may also be expedient to design the outlet flange and mixing element as separate components. This may for example be the case when the mixing element is made very small and sensitive and could occur in the production of the two elements as a single component damage to the mixing element

In Ausgestaltung der Erfindung sind der Auslassflansch und das Mischelement als separate Bauteile ausgeführt und der Auslassflansch weist in Richtung Austragöffnung eine Ausnehmung auf, in die ein Endbereich des Mischelements eintaucht. Insbesondere sind die Ausnehmung des Auslassflanschs und der Endbereich des Mischelements so ausgeführt, dass der Endbereich des Mischelements nur in einer festgelegten Position in die Ausnehmung eintauchen kann. Damit wird zum einen eine sichere Abstützung des Mischelements gegenüber dem Auslassflansch gewährleistet und ausserdem wird sichergestellt, dass das Mischelement immer gleich gegenüber dem Auslassflanschs positioniert ist. Damit wird sichergestellt, dass das Mischelement immer aus einer gewünschten, vorgegebenen Richtung von den Komponenten angeströmt wird. Damit wird immer eine optimale und reproduzierbare Vermischung der Komponenten ermöglicht.In an embodiment of the invention, the outlet flange and the mixing element are designed as separate components, and the outlet flange has a recess in the direction of the discharge opening into which an end region of the mixing element dips. In particular, the recess of the outlet flange and the end region of the mixing element are designed such that the end region of the mixing element can only dip into the recess in a fixed position. This ensures on the one hand a secure support of the mixing element with respect to the outlet flange and also ensures that the mixing element always the same positioned opposite the outlet flange. This ensures that the mixing element is always flown from a desired, predetermined direction of the components. This always allows an optimal and reproducible mixing of the components.

Der Endbereich des Mischelements und damit auch die Ausnehmung können beispielsweise eine ovale oder rechteckige Kontur aufweisen. In diesem Fall kann das Mischelement in zwei unterschiedlichen Stellungen gegenüber dem Auslassflansch positioniert werden. Um nur genau eine Stellung zu gewährleisten, können der Endbereich und die Ausnehmung auch beispielsweise eine fünfeckige Kontur aufweisen, die aus einem Rechteck und einem Dreieck zusammengesetzt ist.The end region of the mixing element and thus also the recess may have, for example, an oval or rectangular contour. In this case, the mixing element can be positioned in two different positions relative to the outlet flange. To ensure only one position, the end portion and the recess may also have, for example, a pentagonal contour, which is composed of a rectangle and a triangle.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich anhand der nachfolgenden Beschreibung von Ausführungsbeispielen sowie anhand der Zeichnungen, in welchen gleiche oder funktionsgleiche Elemente mit identischen Bezugszeichen versehen sind.Further advantages, features and details of the invention will become apparent from the following description of exemplary embodiments and with reference to the drawings, in which the same or functionally identical elements are provided with identical reference numerals.

Gemäss Fig. 1 weist eine Austragvorrichtung 10 für zwei fliessfähige Komponenten einen Vorratsbehälter 11 auf. Der Vorratsbehälter 11 verfügt über eine erste Vorratskammer 12 für eine erste Komponente und eine zweite Vorratskammer 13 für eine zweite Komponente, wobei die Vorratskammern 12, 13 nur teilweise dargestellt sind. Die Vorratskammern 12, 13 weisen eine hohlzylindrische Innenkontur auf und sind parallel zueinander und parallel zu einer Austragrichtung 14 angeordnet. Der Vorratsbehälter 11 verfügt über einen Auslassflansch 15, der die beiden Vorratskammern 12, 13 in Austragrichtung 14 begrenzt und einen ersten Verbindungskanal 16 von der ersten Vorratskammer 12 zu einem ersten Komponentenauslass 17 und einen zweiten Verbindungskanal 18 von der zweiten Vorratskammer 13 zu einem zweiten Komponentenauslass 19 aufweist. In den Vorratskammern 12, 13 ist jeweils ein in Austragrichtung 14 verschiebbarer, nicht dargestellter Kolben angeordnet, mittels welchen die beiden Komponenten aus den Vorratskammern 12, 13 zu ihrem jeweiligen Komponentenauslass 17, 19 gedrückt werden können.According to Fig. 1 For example, a discharge device 10 for two flowable components has a storage container 11. The storage container 11 has a first storage chamber 12 for a first component and a second storage chamber 13 for a second component, wherein the storage chambers 12, 13 are only partially shown. The storage chambers 12, 13 have a hollow cylindrical inner contour and are arranged parallel to one another and parallel to a discharge direction 14. The storage container 11 has an outlet flange 15 which delimits the two storage chambers 12, 13 in the discharge direction 14 and a first connection channel 16 from the first storage chamber 12 to a first component outlet 17 and a second connection channel 18 from the second storage chamber 13 to a second component outlet 19 having. In the storage chambers 12, 13 each a displaceable in discharge 14, not shown piston is arranged, by means of which the two components from the storage chambers 12, 13 can be pressed to their respective component outlet 17, 19.

Der Auslassflansch 15 weist in Austragrichtung 14 abschnittsweise zylinderförmige Mantelflächen mit unterschiedlichen Durchmessern auf. Der erste Komponentenauslass 17 und der zweite Komponentenauslass 19 sind an einer bezüglich der Austragrichtung 14 letzten Mantelfläche 20 des Auslassflanschs 15 angeordnet, wobei erste und der zweite Komponentenauslass 17, 19 in entgegen gesetzte Richtungen orientiert sind. Die Verbindungskanäle 16, 18 weisen keine Öffnung in Austragrichtung 14 auf.The outlet flange 15 has in the discharge 14 partially cylindrical lateral surfaces with different diameters. The first component outlet 17 and the second component outlet 19 are arranged on a last lateral surface 20 of the outlet flange 15 with respect to the discharge direction 14, wherein the first and the second component outlet 17, 19 are oriented in opposite directions. The connecting channels 16, 18 have no opening in the discharge direction 14.

Die Austragvorrichtung 10 verfügt ausserdem über ein Austragelement in Form eines statischen Mischers 21 mit einem Mischergehäuse 22, das einen in Austragrichtung 14 offene Austragsöffnung 23 aufweist. Das Mischergehäuse 22 weist einen rohrförmigen Teil 24 und einen daran entgegen der Austragrichtung 14 angrenzenden Einlassflansch 25 auf. Innerhalb des rohrförmigen Teils 24 ist ein statisches Mischelement 26 angeordnet, durch welches bei einem Austragen der Komponenten eine gute Durchmischung ermöglicht wird. Der Mischer 21 ist mittels des Einlassflanschs 25 mit dem Auslassflansch 15 und damit mit dem Vorratsbehälter 11 verbunden. Der Einlassflansch 25 weist dazu bereichsweise eine mit der Aussenkontur des Auslassflanschs 15 korrespondierende Innenkontur auf.The discharge device 10 also has a discharge element in the form of a static mixer 21 with a mixer housing 22 which has a discharge opening 23 open in the discharge direction 14. The mixer housing 22 has a tubular part 24 and an inlet flange 25 adjoining the discharge direction 14. Within the tubular part 24 is a static mixing element 26 arranged, through which a good mixing is made possible when discharging the components. The mixer 21 is connected by means of the inlet flange 25 with the outlet flange 15 and thus with the reservoir 11. For this purpose, the inlet flange 25 has, in certain regions, an inner contour corresponding to the outer contour of the outlet flange 15.

Der Auslassflansch 15 weist zwischen den Vorratskammern 12, 13 und den Komponentenauslässen 17, 19 einen umlaufenden Bund 27 auf, also einen sich in Austragrichtung 14 ersteckenden Bereich mit einem gegenüber den angrenzenden Bereichen grösseren Aussendurchmesser. Der Einlassflansch 25 verfügt über eine dazu korrespondierende Nut 28, so dass damit eine Rastverbindung zwischen dem Auslassflansch 15 und dem Einlassflansch 25 gebildet wird. Beim Aufschieben des Einlassflanschs 25 auf den Auslassflansch 15 rastet der Bund 27 in die Nut 28 ein, wodurch eine sichere Verbindung zwischen Einlassflansch 25 und Auslassflansch 15 und damit zwischen Mischer 21 und Vorratsbehälter 11 hergestellt wird. Der Einlassflansch 25 weist an seinem der Austragöffnung 23 gegenüber liegenden Rand an der Innenseite eine nicht genauer dargestellte Einführschräge auf, die das Überwinden des Bunds 27 vereinfacht. Der Bund 27 weist zum gleichen Zweck an seiner in Richtung Austragöffnung 23 orientierten Kante eine korrespondierende, ebenfalls nicht genauer dargestellte Schräge auf.The outlet flange 15 has a circumferential collar 27 between the storage chambers 12, 13 and the component outlets 17, 19, that is to say a region which extends in the discharge direction 14 and has a larger outer diameter than the adjacent regions. The inlet flange 25 has a corresponding groove 28, so that thus a latching connection between the outlet flange 15 and the inlet flange 25 is formed. When sliding the inlet flange 25 on the outlet flange 15, the collar 27 engages in the groove 28, whereby a secure connection between the inlet flange 25 and outlet flange 15 and thus between mixer 21 and reservoir 11 is produced. The inlet flange 25 has at its the discharge opening 23 opposite edge on the inside an insertion not shown in detail, which simplifies the overcoming of the collar 27. The collar 27 has, for the same purpose on its oriented in the direction of discharge opening 23 edge on a corresponding, also not shown in detail slope.

Der Bund 27 wird in Richtung Austragöffnung 23 von einer Anschlagfläche 30 begrenzt, an die der Einlassflansch 25 mit einer Gegenfläche 31 anschlägt. Die Anschlagfläche 30 ist so ausgeführt, dass die Gegenfläche 31 des Einlassflanschs 25 die Anschlagfläche 30 des Auslassflanschs 15 nicht oder nur mit extrem hohem Kraftaufwand überwinden kann.The collar 27 is delimited in the direction of the discharge opening 23 by a stop surface 30 against which the inlet flange 25 abuts with a mating surface 31. The stop surface 30 is designed so that the mating surface 31 of the inlet flange 25, the stop surface 30 of the Auslassflanschs 15 can not or only with extremely high expenditure of force overcome.

Der Einlassflansch 25 weist in einem Bereich von der Gegenfläche 31 in Richtung Austragöffnung 23 eine Innenkontur auf, die keine kreisrunden Querschnitte aufweist. Diese Innenkontur ist in Fig. 2, die eine Draufsicht auf einen Schnitt entlang der Linie A-A in der Fig. 1 zeigt, zu sehen. Neben zwei sich gegenüber liegenden Verschlusssegmenten 32, 33 mit einer Innenkontur, die mit der Aussenkontur des Auslassflanschs 15 korrespondiert, weist die Innenkontur des Einlassflanschs 25 einen ersten Überströmkanal 34 und einen dem ersten Überströmkanal 34 gegenüber liegenden zweiten Überströmkanal 35 auf. Zur Bildung der beiden Überströmkanäle 34 und 35 weist die Innenkontur des Einlassflanschs 25 einen gegenüber der Aussenkontur des Auslassflanschs 15 grösseren Durchmesser auf, so dass sich zwischen dem Auslassflansch 25 und dem Einlassflansch 15 jeweils ein Zwischenraum ergibt, die die Überströmkanäle 34, 34 bilden. Die Überströmkanäle 34, 35 erstrecken sich bis zu einem Ende 36 des Auslassflanschs 15, das in Richtung Austragsöffnung 23 orientiert ist, und sind damit über den rohrförmigen Teil 24 des Mischers 21 mit der Austragöffnung 23 verbunden.The inlet flange 25 has an inner contour in a region of the mating surface 31 in the direction of the discharge opening 23, which has no circular cross sections. This inner contour is in Fig. 2 , which is a top view a section along the line AA in the Fig. 1 shows, see. In addition to two opposing closure segments 32, 33 having an inner contour which corresponds to the outer contour of the outlet flange 15, the inner contour of the inlet flange 25 has a first overflow channel 34 and a second overflow channel 35 opposite the first overflow channel 34. In order to form the two overflow channels 34 and 35, the inner contour of the inlet flange 25 has a larger diameter than the outer contour of the outlet flange 15 so that there is a gap between the outlet flange 25 and the inlet flange 15 which form the overflow channels 34, 34. The overflow channels 34, 35 extend to an end 36 of the outlet flange 15, which is oriented in the direction of the discharge opening 23, and are thus connected to the discharge opening 23 via the tubular part 24 of the mixer 21.

Der Einlassflansch 25 kann gegenüber dem Auslassflansch 15 verdreht werden. In einer in den Fig. 1 und 2 dargestellten Schliessposition des Einlassflanschs 25 sind die Verschlusssegmente 32, 33 im Bereich des ersten und zweiten Komponentenauslasses 17 und 19 angeordnet und verhindern damit ein Austreten der Komponenten aus den Komponentenauslässen 17 und 19. In der Schliessposition des Einlassflanschs 25 sind damit der erste und zweite Komponentenauslass 17, 19 durch den Einlassflansch 25 verschlossen. Der erste und zweite Überströmkanal 34 und 35 sind in der Schliessposition jeweils in einem Winkel von 90° zu den Komponentenauslässen 17 und 19 angeordnet.The inlet flange 25 can be rotated relative to the outlet flange 15. In one in the Fig. 1 and 2 illustrated closure position of the inlet flange 25, the closure segments 32, 33 are arranged in the region of the first and second component outlet 17 and 19 and thus prevent leakage of the components from the component outlets 17 and 19. In the closed position of the inlet flange 25 are thus the first and second component outlet 17th , 19 closed by the inlet flange 25. The first and second overflow channels 34 and 35 are each arranged in the closed position at an angle of 90 ° to the component outlets 17 and 19.

Durch ein Verdrehen des Einlassflanschs 25 gegenüber dem Auslassflansch 15 um 90° kann der Einlassflansch 25 in eine in den Fig. 3 und 4 dargestellte Austragposition gebracht werden. In der Austragposition ist der erste Überströmkanal 34 am ersten Komponentenauslass 17 und der zweite Überströmkanal 35 am zweiten Komponentenauslass 19 angeordnet. Damit können wie mit den Pfeilen 37 und 38 symbolisiert, mit einer Verschiebung der in den Vorratskammern 12 und 13 angeordneten Kolben in Austragrichtung 14 die erste Komponente aus der ersten Vorratskammer 12 über den ersten Verbindungskanal 16, den ersten Komponentenauslass 17 und den ersten Überströmkanal 34 zum Mischelement 26 und die zweite Komponente aus der zweiten Vorratskammer 13 über den zweiten Verbindungskanal 18, den zweiten Komponentenauslass 19 und den zweiten Überströmkanal 35 zum Mischelement 26 gedrückt, von diesem vermischt und über die Austragöffnung 23 ausgetragen werden.By rotating the inlet flange 25 with respect to the outlet flange 15 by 90 °, the inlet flange 25 in one in the 3 and 4 shown discharge position can be brought. In the discharge position, the first overflow channel 34 is arranged on the first component outlet 17 and the second overflow channel 35 on the second component outlet 19. Thus, as indicated by the arrows 37 and 38, with a displacement of the arranged in the storage chambers 12 and 13 piston in discharge 14, the first component from the first storage chamber 12 via the first connection channel 16, the first component outlet 17 and the first overflow 34 for Mixing element 26 and the second Component from the second storage chamber 13 via the second connecting channel 18, the second component outlet 19 and the second overflow channel 35 is pressed to the mixing element 26, mixed by this and discharged via the discharge opening 23.

Wie in Fig. 3 zu dargestellt, ist die Anschlagfläche 30 des Austrittsflanschs 15 so ausgeführt, dass auch im gesamten Bereich der Überströmkanäle 34, 35 die Gegenfläche 31 des Einlassflanschs 25 und an der Anschlagfläche 30 anschlägt. Damit können die erste und zweite Komponente von den Komponentenauslässen 17, 19 in der Austragposition des Eintrittsflanschs 15 nur in Austragrichtung 14 und nicht entgegen der Austragrichtung 14 fliessen.As in Fig. 3 To represented, the abutment surface 30 of the outlet flange 15 is designed so that the mating surface 31 of the inlet flange 25 and abuts against the stop surface 30 in the entire region of the overflow channels 34, 35. Thus, the first and second components of the component outlets 17, 19 in the discharge position of the inlet flange 15 can flow only in the discharge 14 and not against the discharge 14.

Das Mischelement 26 und der Vorratsbehälter 11 sind in diesem Ausführungsbeispiel als separate Bauteile ausgeführt. Zur Fixierung und Positionierung des Mischelements 26 gegenüber dem Auslassflansch 15 weist dieser an seinem Ende 36 eine nur in der Fig. 5 dargestellte Ausnehmung 40 auf, in die ein Endbereich 39 des Mischelements 26 eintauchen kann. Damit das Mischelement 26 gegenüber dem Auslassflansch immer richtig positioniert ist, hat die Ausnehmung 40 eine fünfeckige Form, die sich aus einem Rechteck und einem Dreieck zusammensetzt. Der Endbereich 39 des Mischelements 26 hat eine korrespondierende Aussenkontur, so dass das Mischelement 26 nur in genau einer Position in die Ausnehmung 40 gesteckt werden kann.The mixing element 26 and the reservoir 11 are designed in this embodiment as separate components. For fixing and positioning of the mixing element 26 with respect to the outlet flange 15, this has at its end 36 only in the Fig. 5 illustrated recess 40 into which an end portion 39 of the mixing element 26 can dip. So that the mixing element 26 is always correctly positioned relative to the outlet flange, the recess 40 has a pentagonal shape, which is composed of a rectangle and a triangle. The end region 39 of the mixing element 26 has a corresponding outer contour, so that the mixing element 26 can only be inserted into the recess 40 in exactly one position.

Das Mischelement und der Ausgangsflansch und damit der Vorratsbehälter können auch als nur ein einziges Bauteil ausgeführt sein.The mixing element and the output flange and thus the reservoir can also be designed as a single component.
