Description
Die Erfindung betrifft eine Kartusche zum Austrag einer fluiden Füllmasse.The invention relates to a cartridge for discharging a fluid filling compound.
Kartuschen zum Austragen von Füllmassen, welche aus einer oder mehreren Komponenten bestehen können, sind seit langer Zeit in Gebrauch. Hierzu wurden Lösungen entwickelt, welche die Füllmasse einmalig in einer bestimmten Dosierung austragen können, das heisst Einweglösungen. Es gibt auch Kartuschen, für die eine mehrmalige Wiederverwendung grundsätzlich zulässig ist. Das heisst, derartige Kartuschen werden nur teilweise ausgetragen und anschliessend wieder verschlossen. Beim Wiederverschliessen ist darauf zu achten, dass die Füllmasse nicht kontaminiert wird. Insbesondere bei Mehrkomponentenkartuschen, die mehrere reaktionsfähige Komponenten enthalten, würde eine Kontamination dazu führen, dass die Kartusche unbrauchbar wird, weil die reaktionsfähigen Komponenten reagieren und in der Regel aushärten und die Austragsöffnung verstopfen.Cartridges for dispensing fillers, which may consist of one or more components, have been in use for a long time. For this purpose, solutions have been developed which can dispense the filling material once in a certain dosage, ie disposable solutions. There are also cartridges for which repeated reuse is generally permitted. That is, such cartridges are only partially discharged and then closed again. When reclosing, make sure that the filling material is not contaminated. Especially with multi-component cartridges containing multiple reactive components, contamination would render the cartridge unusable because the reactive components react and tend to harden and clog the discharge port.
Es besteht daher im Hinblick auf eine Wiederverwertbarkeit der Kartusche, eine Notwendigkeit, diese derart zu reinigen, dass sie frei von Resten an Füllmasse einer erneuten Verwendung zugänglich gemacht werden kann.Therefore, in view of cartridge reusability, there is a need to clean it in such a way that it can be made available for re-use without residues of filling material.
Ein weiteres Problem ist der Verbleib von Füllmasse in der Kartusche nach Abschluss des Austragvorgangs. Das Austragen erfolgt nicht vollständig, sodass kleine Rückstände an reaktionsfähiger Füllmasse im Vorratsraum verbleiben, die nicht mehr entfernt werden können. Da die Füllmasse oft stark reaktionsfähig ist, ist eine Entsorgung der Kartusche samt der Füllmasse als Sondermüll erforderlich, was ein nicht unbeträchtliches Müllvolumen bedeutet.Another problem is the retention of filler in the cartridge after completion of the discharge process. The discharge is not complete, so that small residues of reactive filling material remain in the reservoir, which can not be removed. Since the filling material is often highly reactive, a disposal of the cartridge together with the filling material is required as hazardous waste, which means a not inconsiderable waste volume.
Ein vorbekanntes Verfahren zum Reinigen einer Kartusche besteht darin, eine Kapsel mit Neutralisationsfluid vorzusehen, wobei die Kapsel nach Abschluss des Austragens durchstochen wird, sodass sich das Neutralisationsfluid in den Vorratsraum ergiesst und allfällige Reste an Füllmasse chemisch neutralisiert. Diese Lösung ist insofern nachteilig, als Teile der Kapsel im Vorratsraum verbleiben können und die Kartusche zwar ohne Bedenken entsorgt werden kann, aber für eine Wiederverwendung nicht mehr geeignet ist.A previously known method for cleaning a cartridge is to provide a capsule with neutralization fluid, wherein the capsule is pierced after completion of the discharge, so that the neutralization fluid pours into the reservoir and chemically neutralizes any residues of filler. This solution is disadvantageous in that parts of the capsule can remain in the reservoir and the cartridge can indeed be disposed of without hesitation, but is no longer suitable for reuse.
In der
Daher ist es Aufgabe der Erfindung, ein Mittel in der Kartusche vorzusehen, die Füllmasse vollständig aus dem Vorratsraum der Kartusche zu entfernen, sowie die Kartusche für eine erneute Verwendung vorzubereiten.Therefore, it is an object of the invention to provide a means in the cartridge to completely remove the filling material from the reservoir of the cartridge, as well as to prepare the cartridge for reuse.
Die Aufgabe der Erfindung wird mittels einer Kartusche zum Austragen einer Füllmasse gelöst, welche einen Vorratsbehälter für die Füllmasse enthält, wobei in dem Vorratsbehälter ein erster Kolben angeordnet ist, mittels welchem der Vorratsbehälter fluiddicht verschliessbar ist und eine Füllmasse im Vorratsbehälter zwischen dem ersten Kolben und einem Austrittskanal lagerbar ist, und der erste Kolben mit einer Druckkraft beaufschlagbar ist, sodass die Füllmasse aus dem Vorratsbehälter durch den Austrittskanal austragbar ist. Der Kolben weist eine der Füllmasse zugewendete Medienseite und eine gegenüberliegende Antriebsseite auf. Ein zweiter Kolben ist in dem Vorratsbehälter angeordnet, der sich auf der Antriebsseite des ersten Kolbens befindet. Der Zwischenraum zwischen dem ersten Kolben und dem zweiten Kolben ist mit einem Spülfluid gefüllt. , Ein Spülelement ist vorgesehen, sodass das Spülfluid nach Abschluss des Austragvorgangs am ersten Kolben vorbei in den Austrittskanal führbar ist.The object of the invention is achieved by means of a cartridge for discharging a filling compound, which contains a reservoir for the filling material, wherein in the reservoir, a first piston is arranged by means of which the reservoir is fluid-tight closable and a filling material in the reservoir between the first piston and an outlet channel is storable, and the first piston can be acted upon with a compressive force, so that the filling material from the reservoir through the outlet channel can be discharged. The piston has one of the filling compound facing media side and an opposite drive side. A second piston is disposed in the reservoir, which is located on the drive side of the first piston. The space between the first piston and the second piston is filled with a purge fluid. , A flushing element is provided so that the flushing fluid after completion of the discharge on the first piston past the drain channel is feasible.
Allfällige Reste von Füllmasse werden somit vom Spülfluid erfasst und mit dem Spülfluid durch den Austrittskanal entsorgt. Somit sind durch das Spülfluid sind Füllmassenreste aus dem Vorratsbehälter austragbar. Hierbei bleiben keinerlei Rückstände der reaktionsfähigen Füllmasse zurück.Any residues of filling material are thus detected by the flushing fluid and disposed of with the flushing fluid through the outlet channel. Thus, by the flushing fluid Füllmassenreste be discharged from the reservoir. In this case, no residues of the reactive filling material remain.
Das Spülelement ist als ein Spülkanal ausgebildet, welcher verschlossen ist, solange sich die Füllmasse im Vorratsbehälter befindet. Der Spülkanal kann beispielsweise im Kolben vorgesehen sein und durch ein Absperrelement verschlossen sein, oder er kann, wie nachfolgend beschrieben, an der Innenwand des Vorratsbehälters verlaufen.The flushing element is designed as a flushing channel, which is closed as long as the filling compound is in the reservoir. The flushing channel may for example be provided in the piston and be closed by a shut-off, or it may, as described below, extend on the inner wall of the reservoir.
Insbesondere kann das Spülelement ein Entlüftungsspalt sein. Ein derartiger Entlüftungsspalt kann wie in der
Insbesondere ist das Spülelement als Erhebung an der Innenwand des Vorratsbehälters ausgebildet. Durch diese Erhebung wird die Dichtung zwischen Kolben und Innenwand lokal unterbrochen, sodass Spülfluid in den Vorratsraum und von dort in den Austrittskanal geführt werden kann. Das Spülelement weist eine Länge auf, die zumindest der Höhe des ersten Kolbens entspricht. Wenn der Kolben auf der Stirnseite des Vorratsbehälters aufliegt, kann das Spülfluid durch das Spülelement am Kolben vorbei geführt werden.In particular, the flushing element is formed as a survey on the inner wall of the reservoir. By this survey, the seal between the piston and the inner wall is locally interrupted, so that flushing fluid can be fed into the reservoir and from there into the outlet channel. The flushing element has a length which corresponds at least to the height of the first piston. When the piston rests on the end face of the reservoir, the flushing fluid can be passed through the flushing element on the piston.
Hierzu ist das Spülelement derart ausgestaltet, dass eine Kolbendichtung des ersten Kolbens von der Innenwand des Vorratsbehälters lösbar ist, wenn der erste Kolben sich in einer Lage befindet, in welcher die Kolbendichtung von der Erhebung erfasst wird, wodurch ein Durchgang für das Spülfluid freigebbar ist. Die Kolbendichtung kann beispielsweise als Kolbenlippe ausgebildet sein, welche auf der Innenwand des Vorratsbehälters aufliegt.For this purpose, the flushing element is configured such that a piston seal of the first piston is detachable from the inner wall of the reservoir when the first piston is in a position in which the piston seal is detected by the survey, whereby a passage for the flushing fluid can be released. The piston seal may be formed, for example, as a piston lip, which rests on the inner wall of the reservoir.
Das Spülelement erstreckt sich an der Innenwand des Vorratsbehälters von dessen Stirnseite über zumindest die Höhe des ersten Kolbens und ist kleiner als die Gesamthöhe des ersten und des zweiten Kolbens.The flushing element extends on the inner wall of the reservoir from the end face over at least the height of the first piston and is smaller than the total height of the first and the second piston.
Eine Mehrzahl von Spülelementen kann vorgesehen sein. Insbesondere können mehrere Spülelemente am Umfang des Vorratsbehälters verteilt sein. Diese Spülelemente sind beispielsweise als Verdrängerrippen ausgebildet.A plurality of flushing elements may be provided. In particular, a plurality of flushing elements may be distributed on the circumference of the storage container. These flushing elements are formed for example as Verdrängerrippen.
Die Viskosität der Füllmasse ist vorteilhafterweise kleiner als die Viskosität des Spülfluids. Wenn das Spülfluid eine geringere Viskosität als die Füllmasse hätte, könnte das Spülfluid an der Füllmasse vorbeiströmen, ohne die Füllmasse mit auszutragen. In diesem Fall ist eine vollständige Spülung des Vorratsraums nicht gewährleistet.The viscosity of the filling compound is advantageously smaller than the viscosity of the flushing fluid. If the flushing fluid had a lower viscosity than the filling compound, the flushing fluid could flow past the filling compound without having to discharge the filling compound. In this case, a complete flushing of the pantry is not guaranteed.
Das Volumen des Spülfluids, welches sich zwischen dem ersten und zweiten Kolben befindet, ist vorteilhafterweise zumindest so gross wie das Volumen des Austrittskanals. Hierdurch ist sichergestellt, dass die Füllmassenreste sicher aus dem Vorratsraum und dem Austrittskanal entfernt sind, wenn die Spülung abgeschlossen ist.The volume of the flushing fluid, which is located between the first and second piston, is advantageously at least as large as the volume of the outlet channel. This ensures that the filler residues are safely removed from the reservoir and the outlet channel when the flush is completed.
Der Vorratsbehälter kann insbesondere eine Innenwand und eine Stirnseite aufweisen, wobei die Stirnseite eine Austrittsöffnung aufweist, an welche der Austrittskanal anschliesst, wobei der Durchmesser der Austrittsöffnung maximal ein Drittel des Durchmessers des Vorratsbehälters beträgt.The reservoir may in particular have an inner wall and an end face, wherein the end face has an outlet opening, which adjoins the outlet channel, wherein the diameter of the outlet opening is a maximum of one third of the diameter of the reservoir.
Die Austrittsöffnung ist das Eintrittsende des Austrittskanals und der Austrittskanal weist ein Austrittsende auf, an welchen ein Mischelement anschliessbar ist.The outlet opening is the inlet end of the outlet channel and the outlet channel has an outlet end to which a mixing element can be connected.
Insbesondere kann die Kartusche als Mehrkomponentenkartusche ausgebildet sein, beispielsweise in der Bauweise der

Der erste Kolben 9 weist eine der Füllmasse 3 zugewendete Medienseite 18 und eine der Medienseite 18 gegenüberliegende Antriebsseite 19 auf. Der erste Kolben 8 ist auf der Antriebsseite 19 mit einer Druckkraft beaufschlagbar, sodass die Füllmasse 3 aus dem Vorratsbehälter 5 durch den Austrittskanal 12 austragbar ist, indem der erste Kolben 8 entlang der Innenwand 6 in Richtung des Austrittskanals 12 bewegt wird.The
Wenn der erste Kolben 8 die Stirnseite 7 erreicht, ist der Vorgang des Austragens abgeschlossen. Zwischen dem ersten Kolben 8 und der Stirnseite 7 sowie im Austrittskanal 12 befindet sich noch Füllmasse 3. Wenn diese Füllmasse 3 eine reaktive Komponente enthält, kann es zu einer chemischen Reaktion im Austrittskanal 12 kommen, welcher mit der Luft der Umgebung in Kontakt ist. Des weiteren stellt eine reaktive Füllmasse nicht selten ein Risiko für die Umwelt dar, sodass eine mit derartiger reaktiver Füllmasse 3 kontaminierte Kartusche 1 bisher als Sondermüll entsorgt werden musste. Daher wird erfindungsgemäss eine Spülung vorgesehen, damit die Füllmasse vollständig aus dem Vorratsraum ausgetragen wird.When the
Hierzu ist ein zweiter Kolben 9 in dem Vorratsbehälter 5 angeordnet. Der zweite Kolben 9 ist auf der Antriebsseite 19 des ersten Kolbens 8 angeordnet. Zwischen dem ersten Kolben 8 und dem zweiten Kolben 9 befindet sich ein Spülfluid 15. Der erste Kolben weist eine Kolbendichtung 20 und der zweite Kolben weist eine Kolbendichtung 30 auf. Das Spülfluid 15 befindet sich zwischen dem ersten Kolben 8 und dem zweiten Kolben 9. Ein Austreten des Spülfluids in den Vorratsraum 5 wird durch die Kolbendichtung 20 verhindert. Ein Austreten des Spülfluids 15 in die Umgebung wird durch die Kolbendichtung 30 verhindert.For this purpose, a
Der zweite Kolben weist eine Medienseite 28 und eine Antriebsseite 29 auf, wobei die Medienseite 28 in Kontakt mit dem Spülfluid 15 ist. Die Antriebsseite 19 des ersten Kolbens 8 ist ebenfalls in Kontakt mit dem Spülfluid 15. Das Spülfluid 15 ist im wesentlichen inkompressibel und verbleibt in dem Zwischenraum 16 zwischen der Medienseite 28 des zweiten Kolbens 9 und der Antriebsseite 19 des ersten Kolbens 8, solange die Kolbendichtungen 20, 30 vollständig auf der Innenwand 6 des Vorratsbehälters 5 aufliegen.The second piston has a
Zum Austrag der Füllmasse 3 wird der zweite Kolben 9 mit einer Druckkraft beaufschlagt. Diese Druckkraft kann beispielsweise durch ein Druckfluid oder durch einen Stössel aufgebracht werden. Beide Varianten sind dem Fachmann bekannt und werden daher zeichnerisch nicht dargestellt. Wenn der zweite Kolben mit einer Druckkraft beaufschlagt wird, wird er in Richtung der Stirnseite 7 verschoben. Gleichzeitig wird der erste Kolben 8 und das im Zwischenraum 16 befindliche Spülfluid 15 mit verschoben. Die Füllmasse 3 verlässt den Vorratsbehälter 5 durch eine Austrittsöffnung 17 und den Austrittskanal 12.To discharge the filling compound 3, the
Um die nach Beendigung des Austragvorgangs im Vorratsraum 4 verbleibende Füllmasse 3 zu entfernen, ist ein Spülelement 11 vorgesehen , sodass das Spülfluid 15 nach Abschluss des Austragvorgangs am ersten Kolben 8 vorbei in den Austrittskanal 12 führbar ist. Allfällige Reste von Füllmasse 3 werden somit vom Spülfluid 15 erfasst und mit dem Spülfluid 15 durch den Austrittskanal 12 ausgeschoben. Somit sind durch das Spülfluid 15 Füllmassenreste vollständig aus dem Vorratsbehälter entfernbar, sodass keinerlei Rückstände der reaktionsfähigen Füllmasse im Vorratsraum 4 zurückbleiben.In order to remove the filling compound 3 remaining in the storage space 4 after completion of the discharge operation, a
