Description

Die vorliegende Erfindung betrifft eine Ausdrückpistole für Doppelwandkartuschen bestehend aus einem handbetätig­ten Pistolengriff, einer wannenförmigen Halbschale, einer verschiebbar darin gelagerten Kolbenstange und einer am vorderen Ende der Kolbenstange angeordneten im wesentli­chen kreisförmigen Ausdrückplatte.The present invention relates to a push-out gun for double-wall cartridges consisting of a manually operated pistol grip, a trough-shaped half-shell, a piston rod slidably mounted therein and a substantially circular push-out plate arranged at the front end of the piston rod.

Ausdrückpistolen für Kartuschen, in denen im allgemeinen pastöse Massen enthalten sind, werden vielfach eingesetzt, um aerosolbetriebene Druckdosen zu ersetzen. Dabei wird die Kartusche derart in die Halbwanne der Ausdrückpistole eingelegt, daß ihr verschiebbarer Kolben von der Ausdrück­platte der Ausdrückpistole beaufschlagt wird, die wiederum durch den Vorschub der Kolbenstange bei Betätigung des Pistolengriffes die pastöse Masse auspreßt. Jedoch ist eine derartige Ausdrückpistole nicht zum gleichzeitigen Auspressen zweier in einer Doppelwandkartusche enthaltenen pastösen Massen geeignet.Squeeze guns for cartridges, which generally contain pasty masses, are widely used to replace aerosol-operated pressure cans. The cartridge is inserted into the half-tub of the squeeze gun in such a way that its displaceable piston is acted upon by the squeeze plate of the squeeze gun, which in turn squeezes the pasty mass through the advance of the piston rod when the pistol grip is actuated. However, such a squeeze gun is not suitable for simultaneously squeezing two pasty masses contained in a double wall cartridge.

Eine derartige Doppelwandkartusche ist in der DE-OS 38 14 633 der Anmelderin beschrieben. Es handelt sich dabei um einen Behälter für pastöse Massen bestehend aus einem zylindrischen Gehäuse, das durch eine in Längsrichtung an­geordnete Trennwand in zwei separate Kammern unterteilt ist, wobei im oberen Ende einer jeden Kammer jeweils eine Auslaßöffnung vorgesehen ist und in jeder Kammer ein halb­kreisförmiger Kolben vorgesehen ist, der in Richtung zur Auslaßöffnung verschiebbar ist. Auf der Unterseite des Kol­bens sind mehrere Rippen vorgesehen und entlang des Außen­randes des Kolbenbodens ist eine Dichtungslippe angeordnet.Such a double wall cartridge is described in DE-OS 38 14 633 by the applicant. It is a container for pasty masses consisting of a cylindrical housing which is divided into two separate chambers by a longitudinally arranged partition wall, an outlet opening being provided in the upper end of each chamber and a semicircular piston being provided in each chamber is, which is displaceable in the direction of the outlet opening. Several ribs are provided on the underside of the piston and a sealing lip is arranged along the outer edge of the piston crown.

Aus dem DE-GM 87 14 548 ist eine handbetätigte Dichtungs­pistole bekannt, die zum Auspressen einer Doppelwandkartu­ sche dient, wobei an der Stirnseite eines handbetätigten Pistolengriffs eine wannenförmige Halbschale angeordnet ist. Parallel zu einer Transportstange ist eine Kolbenstan­ge über ein Joch befestigt, wobei an den vorderen Enden der Transportstange und der Kolbenstange sich jeweils eine halbe Kolbenscheibe befinden, so daß bei gleichzeitiger Be­tätigung der Transportstange und der Kolbenstange ein zeit­gleiches Auspressen der beiden Komponenten aus der Doppel­wandkartusche erfolgt. Nachteilig bei dieser bekannten Dichtungspistole ist jedoch noch, daß bei den erforderli­chen hohen Drücken zur Bewegung der pastösen Massen in den Kammern der Doppelwandkartuschen eine seitliche Aufweitung der einzelnen Kartuschenkammern erfolgt, da diese lose in der wannenförmigen Halbschale liegt und üblicherweise aus einem flexiblen Material gefertigt ist.From DE-GM 87 14 548 a manually operated sealing gun is known, which is used to squeeze out a double-walled cartridge cal serves, with a trough-shaped half-shell is arranged on the front side of a manually operated pistol grip. Parallel to a transport rod, a piston rod is fastened via a yoke, with half a piston disc each at the front ends of the transport rod and the piston rod, so that when the transport rod and the piston rod are actuated simultaneously, the two components are pressed out of the double-wall cartridge at the same time. A disadvantage of this known sealing gun, however, is that at the high pressures required to move the pasty masses in the chambers of the double-wall cartridges, the individual cartridge chambers expand laterally, since this lies loosely in the trough-shaped half-shell and is usually made of a flexible material.

Aufgabe der vorliegenden Erfindung ist es, eine Ausdrück­pistole für Doppelwandkartuschen zu schaffen, mit der ein präzises gleichzeitiges Auspressen der in den beiden Kam­mern enthaltenen pastösen Massen gewährleistet ist und bei der unregelmäßige Aufweitungen der Kartuschenaußenwand mit Sicherheit vermieden sind.The object of the present invention is to provide a squeeze gun for double-wall cartridges with which a precise simultaneous squeezing out of the paste-like masses contained in the two chambers is ensured and with which irregular widenings of the outer wall of the cartridge are avoided with certainty.

Ausgehend von einer Ausdrückpistole der eingangs näher ge­nannten Art wird zur Lösung dieser Aufgabe vorgeschlagen, daß in der wannenförmigen Halbschale lösbar und verschieb­bar ein einseitig offenes zylindrisches Rohr angeordnet ist, in dem zwei im Abstand voneinander angeordnete Stem­pel befestigt sind.On the basis of an ejection gun of the type mentioned in the introduction, it is proposed to solve this problem that a cylindrical tube which is open on one side and in which two stamps arranged at a distance from one another are fastened and displaceable is arranged in the trough-shaped half-shell.

Vorteilhafterweise sind die Stempel in Form eines Zylinder­mantelabschnitts angeordnet und koaxial zum Rohr am Rohrbo­den befestigt.The punches are advantageously arranged in the form of a cylinder jacket section and are fastened to the tube sheet coaxially with the tube.

Bei einem bevorzugten Ausführungsbeispiel besteht das Rohr aus Aluminium, das in seinem Außendurchmesser an den Innen­durchmesser der Wanne angepaßt ist und in seinem Innendurchmesser an den Außendurchmesser der auszudrücken­den Doppelwandkartusche angepaßt ist.In a preferred embodiment, the tube is made of aluminum, the outer diameter of which is adapted to the inner diameter of the tub and the inner diameter of which is adapted to the outer diameter of the double-wall cartridge to be pressed out.

Das einseitig offene zylindrische Rohr mit den beiden da­rin angeordneten Stempeln bietet den Vorteil, daß es von der Ausdrückplatte einer herkömmlichen Ausdrückpistole kon­tinuierlich über die Doppelwandkartusche geschoben wird, wobei die etwas nach rückwärts versetzten Stempelenden die halbkreisförmigen Kolbenböden der beiden Kammern beaufschlagen; entsprechend dem Vorschub des zylindrischen Rohrs bewegen sich die beiden halbkreisförmigen Kolben in Richtung zur Ausdrücköffnung, wobei an den Stellen der größten Beanspruchung der Wandung der Doppelwandkartusche keine Aufweitung nach außen erfolgen kann, da dies durch das zylindrische Rohr, das die Doppelwandkartusche umschließt, mit Sicherheit verhindert wird.The one-sided open cylindrical tube with the two punches arranged in it has the advantage that it is pushed continuously from the ejection plate of a conventional ejection gun over the double-wall cartridge, the somewhat offset piston ends acting on the semicircular piston heads of the two chambers; In accordance with the advance of the cylindrical tube, the two semicircular pistons move in the direction of the ejection opening, with no expansion to the outside at the places where the wall of the double-wall cartridge is subjected to the greatest stress, since this certainly prevents due to the cylindrical tube which encloses the double-wall cartridge becomes.

Aufgrund der Lösbarkeit des zylindrischen Rohrs wird der Vorteil erzielt, daß dieses auch für andere herkömmliche Ausdrückpistolen verwendet werden kann, so daß auch mit diesen bekannten Ausdrückpistolen Doppelwandkartuschen präzise ausgedrückt werden können.Due to the detachability of the cylindrical tube, the advantage is achieved that it can also be used for other conventional squeeze guns, so that double-wall cartridges can also be squeezed precisely with these known squeeze guns.

Im folgenden wird die Erfindung anhand der Zeichnung er­läutert, in der ein vorteilhaftes Ausführungsbeispiel dar­gestellt ist. Es zeigen:

  • Fig. 1 einen Schnitt durch eine Doppelwandkartusche und zu­gehörigem zylindrischen Rohr;
  • Fig. 2 einen Schnitt durch das zylindrische Rohr und die beiden Stempel;
  • Fig. 3a eine Seitenansicht eines Kolbens einer Kammer der Doppelwandkartusche und
  • Fig. 3b eine Unteransicht dieses Kolbens.
The invention is explained below with reference to the drawing, in which an advantageous exemplary embodiment is shown. Show it:
  • Figure 1 shows a section through a double wall cartridge and associated cylindrical tube.
  • 2 shows a section through the cylindrical tube and the two stamps.
  • Fig. 3a is a side view of a piston of a chamber of the double wall cartridge and
  • Fig. 3b is a bottom view of this piston.

In Fig. 1 ist ein Schnitt durch eine Doppelwandkartusche 1 dargestellt, die mit zwei Auslaßöffnungen 2, 3 und einer gegebenenfalls darauf aufschraubbaren Mischspitze versehen ist. In Längsrichtung ist die Doppelwandkartusche 1 durch eine Trennwand 4 in zwei halbkreisförmige Kammern unter­teilt, in denen jeweils eine pastöse Masse angeordnet ist. Der Boden der Doppelwandkartusche 1 wird durch zwei halb­kreisförmige Kolben 5 verschlossen, die in Richtung zur Auslaßöffnung hin verschiebbar sind, wobei wie insbesonde­re Fig. 3b zeigt, die Unterseite eines jeden Klbens mit ei­ner Vielzahl von Verstärkungsringen 10 versehen sein kann.In Fig. 1 a section through a double-wall cartridge 1 is shown, which is provided with two outlet openings 2, 3 and a mixing tip which can be screwed thereon, if necessary. In the longitudinal direction, the double wall cartridge 1 is divided by a partition 4 into two semicircular chambers, in each of which a pasty mass is arranged. The bottom of the double-wall cartridge 1 is closed by two semicircular pistons 5 which can be displaced in the direction of the outlet opening, the bottom side of each piston being able to be provided with a multiplicity of reinforcing rings 10, as shown in particular in FIG. 3b.

Zum gleichzeitigen präzisen Ausdrücken der beiden Komponen­ten wird nun in eine herkömmliche Ausdrückpistole (nicht dargestellt), die aus einem handbetätigten Pistolengriff besteht, einer wannenförmigen Halbschale, einer darin ver­schiebbar gelagerten Kolbenstange und einer am vorderen Ende der Kolbenstange angeordneten im wesentlichen kreis­förmigen Ausdrückplatte, ein einseitig offenes zylindri­sches Rohr 6 eingelegt, in dem zwei im Abstand voneinander angeordnete Stempel 8, 9 befestigt sind. Das zylindrische Rohr 6 ist an seinem der Ausdrückplatte der Ausdrückpisto­le zugeordneten Ende 7 verschlossen, wobei an diesem Boden die beiden Stempel 8, 9 befestigt sind, deren Länge gerin­ger als diejenige des zylindrischen Rohrs 6 ist.To simultaneously express the two components precisely, a conventional one (not shown), which consists of a manually operated pistol grip, a trough-shaped half-shell, a piston rod slidably mounted therein and an essentially circular ejection plate arranged at the front end of the piston rod, is open on one side cylindrical tube 6 is inserted, in which two spaced stamps 8, 9 are fastened. The cylindrical tube 6 is closed at its end 7 assigned to the ejection plate of the ejection gun, the two punches 8, 9, the length of which is shorter than that of the cylindrical tube 6, being fastened to this base.

Die beiden Stempel 8, 9 können, wie in Fig. 2 dargestellt, die Form eines Zylindermantelabschnitts aufweisen, wobei sie im Abstand voneinander derart angeordnet sind, daß in dem zwischen ihnen gebildeten Spalt die Trennwand 4 der Doppelwandkartusche 1 eingreifen kann.The two punches 8, 9 can, as shown in Fig. 2, have the shape of a cylinder jacket section, wherein they are arranged at a distance from each other such that the partition 4 of the double wall cartridge 1 can engage in the gap formed between them.

Das zylindrische Rohr 6 kann vorteilhafterweise aus Alumi­nium bestehen, wobei es in seinem Außendurchmesser an den Innendurchmesser der wannenförmigen Halbschale der Ausdrückpistole angepaßt ist und in seinem Innendurchmes­ser an den Außendurchmesser der auszudrückenden Doppelwand­kartusche 1 angepaßt ist.The cylindrical tube 6 can advantageously consist of aluminum, the outer diameter of which is adapted to the inner diameter of the trough-shaped half-shell of the spray gun and the inner diameter of which is adapted to the outer diameter of the double-wall cartridge 1 to be pressed out.

Nach dem Einlegen des zylindrischen Rohrs in die Ausdrück­pistole und der Doppelwandkartusche 1 dergestalt, daß die beiden Kolben 5 auf den vorderen Enden der Stempel 8, 9 zu ruhen kommen, wird bei Betätigung des Pistolengriffes der Ausdrückpistole die nicht dargestellte Ausdrückplatte gegen den Boden 7 des zylindrischen Rohrs gepreßt, wobei bei anhaltendem Kraftaufwand sich das zylindrische Rohr 6 über die Außenwand der Doppelwandkartusche 1 schiebt, wo­bei mit einer geringen zeitlichen Verzögerung die beiden Stempel 8, 9 auf den Verstärkungsrippen 10 der beiden Kol­ben 5 zu liegen kommen und diese in Richtung zur Auslaßöff­nung der Doppelwandkartusche befördern. Aufgrund des Vor­eilens des vorderen Randes des zylindrischen Rohrs 6 bezüg­lich der vorderen Enden der beiden Stempel 8, 9 wird ein Aufweiten der Außenwand der Doppelwandkartusche 1 verhin­dert, da an den Stellen der größten Druckbelastung diese fest vom zylindrischen Rohr 6 umschlossen wird. Jede Art von ungleichmäßigem Ausdrücken, d.h. ungleich großen Men­gen wird dadurch vermieden.After inserting the cylindrical tube into the squeeze gun and the double-wall cartridge 1 in such a way that the two pistons 5 come to rest on the front ends of the punches 8, 9, when the pistol grip of the squeeze gun is actuated, the squeeze plate, not shown, against the bottom 7 of the cylindrical one Tube pressed, with continued application of force, the cylindrical tube 6 pushes over the outer wall of the double wall cartridge 1, with a short time delay the two punches 8, 9 come to rest on the reinforcing ribs 10 of the two pistons 5 and these in the direction of the outlet opening of the Convey double wall cartridge. Due to the advance of the front edge of the cylindrical tube 6 with respect to the front ends of the two punches 8, 9, widening of the outer wall of the double-wall cartridge 1 is prevented, since the cylindrical tube 6 firmly encloses it at the points of greatest pressure load. Any kind of uneven expressions, ie unequal quantities, is avoided.

Es ist klar, daß das zylindrische Rohr 6 bei entsprechen­den Abmessungen in alle herkömmlichen Ausdrückpistolen ein­setzbar ist, so daß mit diesem auch Doppelwandkartuschen ausgepreßt werden können.It is clear that the cylindrical tube 6 can be used in all conventional squeeze guns with appropriate dimensions, so that double wall cartridges can also be squeezed out with it.
