Description

Die Erfindung betrifft ein Auspressgerät für Massen enthaltende Gebinde, gemäss dem Oberbegriff des Patentanspruchs 1. Weiter betrifft die Erfindung eine Auspressvorrichtung für ein derartiges Auspressgerät, gemäss dem Oberbegriff des Patentanspruchs 4, sowie eine Kassette für ein derartiges Auspressgerät, gemäss dem Oberbegriff des Patentanspruchs 7.The invention relates to a Auspressgerät for mass-containing container, according to the preamble of claim 1. The invention further relates to a squeezing device for such Auspressgerät, according to the preamble of claim 4, and a cassette for such Auspressgerät, according to the preamble of claim. 7

Ein derartiges Auspressgerät dient dem Ausbringen von in Gebinden verpackten Massen, wie Mörtel- oder Dichtmassen, an einem Applikationsort. Gebinde umfassen beispielsweise mit einer oder mehreren Komponenten der auszubringenden Masse befüllte Folienbeutel, die in eine separate oder eine an der Auspressvorrichtung angeordnete Kassette eingesetzt werden.Such Auspressgerät serves to dispense packaged in containers masses, such as mortar or sealants, at an application site. Containers comprise, for example, foil bags filled with one or more components of the mass to be delivered, which are inserted into a separate cassette or a cassette arranged on the ejection device.

Aus der US 2,788,159 ist ein Auspressgerät für Massen enthaltende Gebinde bekannt, das eine Auspressvorrichtung und eine Kassette für das Gebinde aufweist. Die Auspressvorrichtung weist eine Auspresseinrichtung und eine Aufnahme für die Kassette auf, wobei die Aufnahme frontseitig von einer Kopfplatte und rückseitig von einer Gehäusewand der Auspresseinrichtung begrenzt ist. Die Kassette umfasst einen Aufnahmekörper in dem ein Gebinde oder die auszupressende Masse direkt angeordnet wird. Die Kassette wird in die Aufnahme der Auspressvorrichtung eingelegt und mittels Betätigung der Auspresseinrichtung, welche beispielsweise eine Kolbenstange mit Druckstück umfasst, ausgepresst.From the US 2,788,159 is a dispensing device for mass-containing container is known which has a squeezing device and a cassette for the container. The squeezing device has a squeezing device and a receptacle for the cassette, wherein the receptacle is delimited on the front side by a head plate and on the rear by a housing wall of the squeezing device. The cassette comprises a receiving body in which a container or the mass to be squeezed out is placed directly. The cassette is inserted into the receptacle of the squeezing device and pressed out by actuation of the squeezing device, which comprises, for example, a piston rod with a pressure piece.

Nachteilig an der bekannten Lösung ist, dass für einen reibungslosen Auspressvorgang die separate Kassette exakt in der Aufnahme der Auspressvorrichtung positioniert werden muss und dass dazu seitens des Anwenders mehrere Handgriffe erforderlich sind.A disadvantage of the known solution is that for a smooth Auspressvorgang the separate cassette must be positioned exactly in the recording of the squeezing and that on the part of the user several handles are required.

Aus der US 6,082,597 ist ein gattungsgemässes Auspressgerät für Massen enthaltende Gebinde bekannt, das eine Auspressvorrichtung und eine Kassette für das Gebinde aufweist. Die Auspressvorrichtung weist eine Auspresseinrichtung und eine Aufnahme für die Kassette auf. Die Kassette ist um eine, senkrecht zur Auspressrichtung stehende Schwenkachse verschwenkbar an der Auspressvorrichtung festgelegt und von einer Auspressstellung in eine Beladestellung überführbar.From the US 6,082,597 a generic Auspressgerät for mass-containing container is known which has a squeezing device and a cassette for the container. The squeezing device has a squeezing device and a receptacle for the Cassette on. The cassette is pivotable about a, perpendicular to the extrusion direction pivot axis fixed to the squeezing and can be transferred from a Auspressstellung in a loading position.

Nachteilig an der bekannten Lösung ist, dass die beim Auspressen der Masse auftretenden Kräfte von den die Schwenkachse ausbildenden Befestigungspunkten der Kassette an der Auspressvorrichtung übernommen werden müssen. Um die Gebrauchstauglichkeit des Auspressgerätes zu gewährleisten, müssen die Befestigungspunkte entsprechend massiv ausgebildet werden.A disadvantage of the known solution is that the forces occurring during the extrusion of the mass must be taken over by the pivot axis forming attachment points of the cassette on the squeezing. To ensure the serviceability of the Auspressgerätes, the attachment points must be made correspondingly solid.

Aufgabe der Erfindung ist es, ein Auspressgerät für Massen enthaltende Gebinde zu schaffen, das die vorgenannten Nachteile nicht aufweist und bei dem ein einfaches Handling gegeben ist. Weiter ist es Aufgabe der Erfindung, eine Auspressvorrichtung für ein derartiges Auspressgerät sowie eine Kassette für ein derartiges Auspressgerät zu schaffen.The object of the invention is to provide a Auspressgerät for mass-containing container, which does not have the aforementioned disadvantages and in which a simple handling is given. It is another object of the invention to provide a Auspressvorrichtung for such Auspressgerät and a cassette for such Auspressgerät.

Die Aufgaben sind durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen dargelegt.The objects are achieved by the features of the independent claims. Advantageous developments are set forth in the subclaims.

Gemäss der Erfindung ist beim Auspressgerät die Aufnahme der Auspressvorrichtung frontseitig von einer Kopfplatte sowie rückseitig von einer Gehäusewand der Auspresseinrichtung begrenzt und die Schwenkachse verläuft von der Kopfplatte zur Gehäusewand.According to the invention, the receptacle of the extrusion device is delimited at the front by a head plate and at the rear by a housing wall of the extrusion device and the pivot axis extends from the top plate to the housing wall.

Die Schwenkachse verläuft somit parallel zur Längserstreckung der Aufnahme beziehungsweise parallel zur Auspressrichtung der Auspressvorrichtung. Vorteilhaft verläuft die Schwenkachse entlang einer die Aufnahme seitlich begrenzenden Seitenwand oder einer Seitenbegrenzung, z. B. einer Zugstange, der Aufnahme. Die Kassette ist schwenkbar mit der Auspressvorrichtung zumindest teilweise verbunden, was eine einfache Beladung durch Ein- und Ausschwenken der Kassette in bzw. aus der Aufnahme der Auspressvorrichtung ermöglicht. Da die Kassette mit der Auspressvorrichtung verbunden ist, kann diese im Betrieb wie auch bei einer Manipulation des Auspressgerätes nicht unbeabsichtigt herunterfallen.The pivot axis thus runs parallel to the longitudinal extent of the receptacle or parallel to the extrusion direction of the extrusion device. Advantageously, the pivot axis extends along a recording laterally limiting side wall or a side boundary, z. B. a pull rod, the recording. The cassette is pivotally connected to the squeezing device at least partially, which allows easy loading by pivoting the cassette in and out of the recording of the squeezing. Since the cassette is connected to the squeezing device, it can not accidentally fall down during operation as well as during manipulation of the squeezing device.

Die Kassette weist in dem Zustand, in dem sie an der Auspressvorrichtung festgelegt ist, nur noch einen Freiheitsgrad auf, in dem diese verschwenkt beziehungsweise gedreht werden kann. Somit ist die Kassette im eingeschwenkten Zustand, in dem die Kassette sich in der Aufnahme der Auspressvorrichtung in der Auspressstellung befindet, eindeutig positioniert, was den Aufwand zur Beladung des Auspressgerätes massgeblich reduziert.The cassette has in the state in which it is fixed to the squeezing, only one degree of freedom in which it can be pivoted or rotated. Thus, the cassette in the pivoted state, in which the cassette is in the recording of Auspressvorrichtung in the Auspressstellung, clearly positioned, which significantly reduces the burden of loading the Auspressgerätes.

Die Auspressvorrichtung zeichnet sich insbesondere durch ein einfaches Handling aus. Eine Hand hält das Auspressgerät mit der Kassette und die andere Hand hält das Gebinde. Die Kassette wird vorteilhaft mit der zuvor das Gebinde haltenden Hand verschwenkt, um diese in die Auspressstellung beziehungsweise in die Beladestellung zu bringen.The ejection device is characterized in particular by a simple handling. One hand holds the ejection device with the cassette and the other hand holds the container. The cassette is advantageously pivoted with the hand previously holding the container to bring it into the Auspressstellung or in the loading position.

Die Lagerung der Kassette ist aufgrund dieser Ausgestaltung des Auspressgerätes zu keinem oder nur zu einem geringen Teil der beim Auspressen auftretenden Kräfte ausgesetzt. Somit kann die Lagerung der Kassette an der Auspressvorrichtung einfach und kostengünstig ausgestaltet werden.The storage of the cassette is exposed due to this design of the Auspressgerätes to no or only a small part of the forces occurring during pressing. Thus, the storage of the cassette to the squeezing device can be designed easily and inexpensively.

Vorzugsweise ist die Kassette lösbar an der Auspressvorrichtung angeordnet, womit diese bedarfsweise vollständig von der Auspressvorrichtung abnehmbar ist. Angebrochene, noch nicht vollständig ausgepresste Gebinde können mit der Kassette von der Auspressvorrichtung entfernt und durch ein andere Kassette mit einem neuen Gebinde ersetzt werden. Ein angebrochenes Gebinde ist in der von der Auspressvorrichtung entfernten Kassette bis zu einer weiteren, zeitlich verzögerten Verwendung lagerbar.Preferably, the cassette is detachably mounted on the squeezing device, whereby it is completely removable, if necessary, from the squeezing device. Opened, not completely squeezed containers can be removed with the cassette from the squeezing and replaced by another cassette with a new container. An opened container can be stored in the cassette removed from the ejection device until further delayed use.

Vorteilhaft ist bei einer lösbar an der Auspressvorrichtung anordnenbaren Kassette deren Lagerung derart ausgebildet, dass die Kassette nur in einer bestimmten Winkelstellung von der Auspressvorrichtung entfernt werden kann. Dadurch wird ein unerwünschtes Lösen der Kassette von der Auspressvorrichtung z. B. beim Verschwenken derselben weitgehend ausgeschlossen.Advantageously, in a releasably attachable to the squeezing device cassette whose storage is designed such that the cassette can be removed only in a certain angular position of the squeezing. As a result, an undesired release of the cassette from the squeezing z. B. when pivoting the same largely excluded.
