- a hand-held device for dispensing multicomponent masses is known.
- the device In order to prevent a return stroke of the piston rods when gripping the first clamping lever serving for the advance, the device has a second clamping lever for each piston rod, which serves to lock the corresponding piston rod.
- the second clamping levers must be unlocked to pull the piston rods back into their starting position. This is done by an unlocking lever engaging the second clamping lever.
- the design of the feed mechanism and the unlocking mechanism has proven to be disadvantageous in this known extrusion device.
- the first clamping lever serving to advance the piston rod is received in a central entrainment element which is arranged on the piston rod in such a way that in its starting position it lies against a stop surface which is perpendicular to the longitudinal extension of the piston rod.
- the first clamping lever is pivoted with respect to the piston rod, so that the clamping lever is jammed with respect to the shaft of the piston rod.
- the piston rod is actually advanced only when the trigger is actuated further.
- part of the maximum possible actuation path of the trigger is always required for the clamping of the clamping lever relative to the piston rod. This has an adverse effect on the handling of the squeezing device and with regard to the processing time of the masses arranged in the cartridges.
- a further disadvantage is the unlocking mechanism, in which the unlocking lever acts on the second clamping lever serving to lock the piston rod.
- the unlocking lever acts on the second clamping lever serving to lock the piston rod.
- the invention has for its object to form a squeezing device, the actuation path of the trigger lever is used entirely to advance the piston rod, prevents damage in the front region by the piston rod and can be produced economically.
- the axial stop of the first clamping plate is formed by the trigger lever, which can be pivoted between two end stops and the first clamping plate interacts essentially simultaneously with the second clamping plate with the unlocking lever.
- the clamping lever can be pivoted so far against the pressing-out direction with the aid of a compression spring that it already assumes the actual clamping position in its starting position.
- the entire actuation path of the trigger lever thus serves entirely to advance the piston rod.
- the trigger can also be moved at the same time as the piston rod is pulled back into its starting position.
- a transmission element is preferably arranged between the first clamping lever and the second clamping lever.
- the transmission element which can be actuated by the unlocking lever can be formed at least in one piece and cooperate with the first clamping lever and with the first and the second clamping lever.

- a transmission element is expediently arranged between the unlocking lever and the first clamping lever.
- Such a transmission element is designed such that when the unlocking lever is actuated, the second clamping lever is actuated by the unlocking lever and the first clamping lever is actuated via a transmission element which encompasses or overlaps the second clamping lever.
- the device 1 shown has a tubular middle part 2, into which a film bag 3 containing a mass is inserted, the nozzle 4 of which rests on the front region 1 a of the device 1 on the pressing-out direction.
- connection piece 5 At the rear area 2b of the middle part 2, a connection piece 5 is arranged which receives the feed mechanism 6. A piston rod 7 is guided through the connecting piece 5 and carries a piston 8 at its front end.
- the connecting piece 5 has a handle 9, to which a trigger lever 11 is fastened so that it can pivot about an axis 10 in the direction of the handle 9.
- the trigger 11 is pivoted counterclockwise about the axis 10, so that the piston rod 7 moves axially in the pressing direction and a piston 8 arranged on the piston rod 7 interacts with the rear region of the film bag 3.

- the trigger lever 11 itself can be pivoted between two end stops 5b, 5c arranged on the connecting piece 5.
- the first clamping lever 12 and the second clamping lever 13 each have a through hole 12a, 13a, which is designed somewhat wider than the diameter of the piston rod 7, so that the latter can move freely relative to the clamping levers 12, 13 arranged at right angles. Since the first clamping lever 12 is already in its clamping position in its starting position due to the one-sided abutment against the stop 11a of the trigger lever 11, this is only axially displaced together with the piston rod 7 when the trigger lever 11 is actuated. During the advancement of the piston rod 7, the mouth areas of the through-hole 12a of the first clamping lever 12 press onto the shaft 7a of the piston rod 7 and clamp together with the latter.
- the second clamping lever 13 secures the piston rod 7 in the position brought about by the first clamping lever 12.

Abstract
Description
Die Erfindung betrifft ein Gerät zum Auspressen von ein- oder mehrkomponentige Massen enthaltende Folienbeutel bzw. Kartuschen mit wenigstens einer Kolbenstange und wenigstens einem Vorschubmechanismus, der wenigstens zwei auf der Kolbenstange angeordnete, axial versetzbare, in Längsrichtung des Gerätes schwenkbare Klemmhebel, wenigstens zwei mit den Klemmhebeln zusammenwirkende Fedem, einen Abzughebel und einen Entriegelungshebel aufweist, wobei ein erster Klemmhebel dem Vorschub der Kolbenstange, ein zweiter Klemmhebel der Verriegelung der Kolbenstange dient und der Entriegelungshebel mit dem zweiten Klemmhebel sowie mit der Kolbenstange zusammenwirkt.The invention relates to a device for squeezing film bags or cartridges containing one or more components with at least one piston rod and at least one feed mechanism, the at least two axially displaceable clamping levers arranged on the piston rod and pivotable in the longitudinal direction of the device, at least two with the clamping levers co-operating springs, a trigger lever and an unlocking lever, a first clamping lever serving to advance the piston rod, a second clamping lever locking the piston rod and the unlocking lever cooperating with the second clamping lever and with the piston rod.
Ein- oder mehrkomponentige Massen werden heute für verschiedenste Anwendungen bei Gebäuden, Kraftfahrzeugen, Schiffen, Flugzeugen, Maschinen, Instrumenten und zahlreichen anderen Vorrichtungen verwendet. Um dem Benutzer eine bequeme Handhabung zu ermöglichen, werden die Massen gewöhnlich in kleineren Behältern mit Kartuschen oder Folienbeuteln angeboten, die in ein entsprechendes Gerät zum Auspressen der Massen einsetzbar sind.Single or multi-component masses are used today for a wide variety of applications in buildings, motor vehicles, ships, aircraft, machines, instruments and numerous other devices. In order to allow the user convenient handling, the masses are usually offered in smaller containers with cartridges or plastic bags which can be used in a corresponding device for squeezing out the masses.
Aus der CH-PS 663 733 ist ein Handgerät zum Abgeben von mehrkomponentigen Massen bekannt. Um einen Rückhub der Kolbenstangen beim Nachgreifen des dem Vorschub dienenden ersten Klemmhebels zu verhindem, weist das Gerät für jede Kolbenstange je einen zweiten Klemmhebel auf, welcher der Verriegelung der entsprechenden Kolbenstange dient. Für das Zurückziehen der Kolbenstangen in ihre Ausgangsstellung müssen die zweiten Klemmhebel entriegelt werden. Dies erfolgt durch einen an dem zweiten Klemmhebel angreifenden Entriegelungshebel.From CH-PS 663 733 a hand-held device for dispensing multicomponent masses is known. In order to prevent a return stroke of the piston rods when gripping the first clamping lever serving for the advance, the device has a second clamping lever for each piston rod, which serves to lock the corresponding piston rod. The second clamping levers must be unlocked to pull the piston rods back into their starting position. This is done by an unlocking lever engaging the second clamping lever.
Als nachteilig erweist sich bei diesem bekannten Auspressgerät die Ausgestaltung des Vorschub-und des Entriegelungsmechanismus. Der dem Vorschub der Kolbenstange dienende erste Klemmhebel findet in einem zentralen Mitnahmeelement Aufnahme, welches derartig auf der Kolbenstange angeordnet ist, dass es in seiner Ausgangsstellung an einer Anschlagfläche anliegt, die rechtwinklig zur Längserstreckung der Kolbenstange verläuft. Beim Betätigen des Abzughebels wird der erste Klemmhebel gegenüber der Kolbenstange verschwenkt, so dass eine Verklemmung des Klemmhebels gegenüber dem Schaft der Kolbenstange erfolgt. Erst bei weiterem Betätigen des Abzugshebels erfolgt der eigentliche Vorschub der Kolbenstange. Bei einem derartig ausgebildeten Vorschubmechanismus wird immer ein Teil des maximal möglichen Betätigungsweges des Abzughebels für die Verklemmung des Klemmhebels gegenüber der Kolbenstange benötigt. Dies wirkt sich auf die Handhabung des Auspressgerätes und im Hinblick auf die Verarbeitungszeit der in den Kartuschen angeordneten Massen nachteilig aus.The design of the feed mechanism and the unlocking mechanism has proven to be disadvantageous in this known extrusion device. The first clamping lever serving to advance the piston rod is received in a central entrainment element which is arranged on the piston rod in such a way that in its starting position it lies against a stop surface which is perpendicular to the longitudinal extension of the piston rod. When the trigger lever is actuated, the first clamping lever is pivoted with respect to the piston rod, so that the clamping lever is jammed with respect to the shaft of the piston rod. The piston rod is actually advanced only when the trigger is actuated further. With a feed mechanism designed in this way part of the maximum possible actuation path of the trigger is always required for the clamping of the clamping lever relative to the piston rod. This has an adverse effect on the handling of the squeezing device and with regard to the processing time of the masses arranged in the cartridges.
Bei der Verwendung von nicht gehärteten Kolbenstangen können Verschleisserscheinungen im Schaftbereich der Kolbenstange auftreten. Diese Verschleisserscheinungen machen sich als Durchmesserverkleinerungen der Kolbenstange bemerkbar. Um einen dem Vorschub dienenden ersten Klemmhebel in Klemmstellung gegenüber einer derart verschliessenden Kolbenstange zu bringen, wird mehr Betätigungsweg des Abzughebels benötigt, so dass weniger Betätigungsweg für den eigentlichen Vorschub zu der Kolbenstange zur Verfügung steht.If non-hardened piston rods are used, signs of wear can occur in the shaft area of the piston rod. These signs of wear become noticeable as a reduction in the diameter of the piston rod. In order to bring a first clamping lever serving the feed into the clamping position in relation to a piston rod that closes in this way, more actuation path of the trigger lever is required, so that less actuation path is available for the actual feed to the piston rod.
Einen weiteren Nachteil bildet der Entriegelungsmechanismus, bei dem der Entriegelungshebel auf die zweiten, der Verriegelung der Kolbenstange dienenden Klemmhebel wirkt. Erreicht die Kolbenstange am Ende des Auspressvorganges ihre auspressrichtungsseitige, vordere Endlage, so wirken auf der Kolbenstange angeordnete Betätigungselemente auf einen Entriegelungshebel. Dadurch wird die Kolbenstange in ihrer vordersten Endlage nicht verriegelt. Eine über den Abzughebel auf den ersten Klemmhebel übertragene Kraft wirkt dennoch zur Gänze auf den auspressrichtungsseitig angeordneten, vorderen Bereich des Gerätes. Somit können Beschädigungen in jenem Bereich auftreten, die schlussendlich zu einer Zerstörung des Gerätes führen.A further disadvantage is the unlocking mechanism, in which the unlocking lever acts on the second clamping lever serving to lock the piston rod. When the piston rod reaches its front end position on the pressing-out direction at the end of the pressing-out process, actuating elements arranged on the piston rod act on an unlocking lever. As a result, the piston rod is not locked in its foremost end position. A force transmitted to the first clamping lever via the trigger lever nevertheless acts entirely on the front area of the device arranged on the pressing-out direction. This can result in damage in that area, which in the end leads to the destruction of the device.
Der Erfindung liegt die Aufgabe zugrunde, ein Auspressgerät auszubilden, dessen Betätigungsweg des Abzughebels zur Gänze dem Vorschub der Kolbenstange dient, die Beschädigung im vorderen Bereich durch die Kolbenstange verhindert und sich wirtschaftlich herstellen lässt.The invention has for its object to form a squeezing device, the actuation path of the trigger lever is used entirely to advance the piston rod, prevents damage in the front region by the piston rod and can be produced economically.
Erfindungsgemäss wird dies dadurch erreicht, dass der axiale Anschlag der ersten Klemmplatte von dem Abzughebel gebildet wird, der zwischen zwei Endanschlägen schwenkbar ist und die erste Klemmplatte im wesentlichen gleichzeitig mit der zweiten Klemmplatte mit dem Entriegelungshebel zusammenwirkt.This is achieved according to the invention in that the axial stop of the first clamping plate is formed by the trigger lever, which can be pivoted between two end stops and the first clamping plate interacts essentially simultaneously with the second clamping plate with the unlocking lever.
Dadurch, dass der Anschlag des ersten Klemmhebels für den Vorschub von dem Abzughebel gebildet wird, kann der Klemmhebel mit Hilfe einer Druckfeder entgegen der Auspressrichtung derartig weit verschwenkt werden, so dass er in seiner Ausgangsstellung schon die eigentliche Klemmposition einnimmt. Der gesamte Betätigungsweg des Abzughebels dient somit zur Gänze dem Vorschub der Kolbenstange.Because the stop of the first clamping lever for the feed is formed by the trigger, the clamping lever can be pivoted so far against the pressing-out direction with the aid of a compression spring that it already assumes the actual clamping position in its starting position. The entire actuation path of the trigger lever thus serves entirely to advance the piston rod.
Nachdem die Kolbenstange ihre vorderste Endlage erreicht hat, werden über das auf der Kolbenstange angeordnete Betätigungselement der Kolbenstange nicht nur der zweite Klemmhebel, sondern auch gleichzeitig der erste Klemmhebel in die rechtwinklige Position gegenüber der Kolbenstange verschwenkt. Wird der Abzughebel betätigt, wenn die Kolbenstange in ihrer vordersten Position angelangt ist, so drückt das Betätigungselement auf den Entriegelungshebel, so dass sich der Abzughebel ohne eine Kraft zu übertragen, frei durchziehen lässt. Somit ist es nicht möglich, auf die Kolbenstange über den Abzughebel eine Kraft auszuüben, die eine Beschädigung im auspressrichtungsseitigen, vorderen Bereich des Gerätes hervorruft.After the piston rod has reached its foremost end position, not only the second clamping lever but also the first clamping lever are pivoted into the right-angled position relative to the piston rod via the actuating element of the piston rod arranged on the piston rod. If the trigger is actuated when the piston rod has reached its foremost position, the actuating element presses on the unlocking lever, so that the trigger can be pulled freely without transmitting any force. Thus, it is not possible to exert a force on the piston rod via the trigger lever, which causes damage in the front area of the device on the pressing-out direction.
Um ein Zurückziehen der Kolbenstange in ihre Ausgangsstellung zu ermöglichen, ist es notwendig, den Entriegelungshebel von Hand in die Entriegelungsstellung zu drücken. Wird der Entriegelungshebel von Hand betätigt, so ist auch gleichzeitig mit dem Zurückziehen der Kolbenstange in ihre Ausgangsstellung ein Bewegen des Abzughebels möglich.In order to enable the piston rod to be pulled back into its starting position, it is necessary to push the unlocking lever into the unlocking position by hand. If the unlocking lever is operated by hand, the trigger can also be moved at the same time as the piston rod is pulled back into its starting position.
Vorzugsweise ist zwischen dem ersten Klemmhebel und dem zweiten Klemmhebel ein Uebertragungselement angeordnet. Um eine einfache Uebertragung der im wesentlichen axialen Bewegung des zweiten Klemmhebels auf den ersten Klemmhebel gewährleisten zu können, kann das von dem Entriegelungshebel betätigbare Uebertragungselement wenigstens einteilig ausgebildet sein und mit dem ersten Klemmhebel sowie mit dem ersten und dem zweiten Klemmhebel zusammenwirken. Ein derartig ausgebildetes Uebertragungselement muss derart ausgebildet sein, dass in der Ausgangsstellung des Gerätes ein axiales Spiel zwischen dem ersten und dem zweiten Klemmhebel besteht. Dieses Spiel muss derart gross sein, dass der erste am Abzughebel anschlagende Klemmhebel in seine Klemmstellung gegenüber der Kolbenstange verschwenkt werden kann, ohne dass er mit dem Uebertragungselement in Berührung kommt.A transmission element is preferably arranged between the first clamping lever and the second clamping lever. In order to be able to ensure a simple transmission of the essentially axial movement of the second clamping lever to the first clamping lever, the transmission element which can be actuated by the unlocking lever can be formed at least in one piece and cooperate with the first clamping lever and with the first and the second clamping lever. Such a transmission element must be designed in such a way that there is axial play between the first and the second clamping lever in the starting position of the device. This play must be so great that the first clamping lever striking the trigger lever can be pivoted into its clamping position with respect to the piston rod without it coming into contact with the transmission element.
Zweckmässigerweise ist zwischen dem Entriegelungshebel und dem ersten Klemmhebel ein Uebertragungselement angeordnet. Ein derartiges Uebertragungselement ist derartig ausgebildet, dass beim Betätigen des Entriegelungshebels der zweite Klemmhebel vom Entriegelungshebel und der erste Klemmhebel über ein den zweiten Klemmhebel um-oder übergreifendes Uebertragungselement betätigt wird.A transmission element is expediently arranged between the unlocking lever and the first clamping lever. Such a transmission element is designed such that when the unlocking lever is actuated, the second clamping lever is actuated by the unlocking lever and the first clamping lever is actuated via a transmission element which encompasses or overlaps the second clamping lever.
Die Erfindung wird, anhand eines Ausführungsbeispieles, näher erläutert.The invention is explained in more detail using an exemplary embodiment.
Das dargestellte Gerät 1 hat ein rohrförmiges Mittelteil 2, in das eine Masse enthaltender Folienbeutel 3 eingesetzt ist, deren Düse 4 an dem auspressrichtungsseitigen, vorderen Bereich 1a des Gerätes 1 anliegt.The device 1 shown has a
Am rückwärtigen Bereich 2b des Mittelteiles 2 ist ein Anschlussstück 5 angeordnet, das den Vorschubmechanismus 6 aufnimmt. Durch das Anschlussstück 5 ist eine Kolbenstange 7 geführt, die an ihrem vorderen Ende einen Kolben 8 trägt. Das Anschlussstück 5 weist ein Griffstück 9 auf, an dem um eine Achse 10 in Richtung des Griffstücks 9 schwenkbar ein Abzugshebel 11 befestigt ist.At the
Zum Auspressen der Masse in den Folienbeutel 3 wird der Abzughebel 11 im Gegenuhrzeigersinn um die Achse 10 verschwenkt, so dass sich die Kolbenstange 7 axial in Auspressrichtung bewegt und ein auf der Kolbenstange 7 angeordneter Kolben 8 mit dem rückwärtigen Bereich des Folienbeutels 3 zusammenwirkt.To squeeze the mass into the
Der Vorschub der Kolbenstange 7 erfolgt durch einen ersten Klemmhebel 12, der von einer ersten Druckfeder 14 entgegen der Auspressrichtung gegen einen am Abzughebel 11 angeordneten Anschlag 11a drückbar ist. Der Abzughebel 11 selber ist zwischen zwei am Anschlussstück 5 angeordneten Endanschlägen 5b, 5c schwenkbar. Der erste Klemmhebel 12 und der zweite Klemmhebel 13 weisen je eine Durchgangsbohrung 12a, 13a auf, die etwas weiter als der Durchmesser der Kolbenstange 7 ausgebildet ist, so dass letztere gegenüber den rechtwinklig angeordneten Klemmhebeln 12, 13 frei beweglich ist. Da sich der erste Klemmhebel 12 in seiner Ausgangsstellung durch die einseitige Anlage am Anschlag 11a des Abzughebels 11 bereits in Klemmstellung befindet, wird dieser bei der Betätigung des Abzughebels 11 nur noch zusammen mit der Kolbenstange 7 axial versetzt. Während des Vorschubes der Kolbenstange 7 drücken die Mündungsbereiche der Durchgangsbohrung 12a des ersten Klemmhebels 12 auf den Schaft 7a der Kolbenstange 7 und verklemmen sich mit diesem.The piston rod 7 is advanced by a
Der zweite Klemmhebel 13 sichert die Kolbenstange 7 in der durch den ersten Klemmhebel 12 herbeigeführten Lage. Der zweite Klemmhebel 13 ruht pendelnd in einer nicht dargestellten Ausnehmung des Anschlussstückes 5 auf und wird durch eine Druckfeder 15 gegenüber dem Schaft 7a der Kolbenstange 7 verschwenkt. Der vorrückenden Kolbenstange 7 gibt der zweite Klemmhebel 13 nach, jeden Rückhub fängt der Klemmhebel 13 infolge seiner Verklemmung gegenüber der Kolbenstange 7 auf. Nach dem Loslassen des Abzughebels 11 geht der erste Klemmhebel 12 wiederum in seine Ausgangslage zurück und es kann je nach Bedarf sofort oder später ein neuer Vorschubhub erfolgen, bis die im Gerät 1 eingesetzte Kartusche 3 entleert ist.The
Nachdem der sich in dem Gerät 1 befindliche Folienbeutel 3 ausgepresst ist, befindet sich die Kolbenstange 7 in ihrer vordersten Endlage. Um eine Beschädigung des auspressrichtungsseitigen, vorderen Bereiches 1a des Gerätes 1 zu verhindern, wirkt ein auf der Kolbenstange 7 angeordnetes Betätigungselement 16 mit einem am Anschlussstück 5 angeordneten, in Längsrichtung des Gerätes 1 schwenkbaren Entriegelungshebel 17 zusammen, der im wesentlichen gleichzeitig auf den ersten Klemmhebel 12 und den zweiten Klemmhebel 13 wirkt. Bei der Betätigung des Entriegelungshebels 17, die auch von Hand erfolgen kann, werden beide Klemmhebel 12, 13 in ihre vertikale, rechtwinklig zur Längsrichtung der Kolbenstange 7 verlaufende Lage verschwenkt, so dass die Kolbenstange 7 gegenüber den Klemmhebeln 12, 13 frei verschieblich ist. Ueber ein geeignetes Uebertragungselement 18 wird die von dem Entriegelungshebel 17 ausgehende Bewegung auf den ersten Klemmhebel 12 und zweiten Klemmhebel 13 übertragen.After the
Das auf der Kolbenstange 7 angeordnete Betätigungselement 16 weist Auflaufschrägen 16a auf, die mit entsprechenden, am Entriegelungshebel 17 angeordneten Auflaufschrägen 17a zusammenwirken.The actuating
