Beschreibung description

Die vorliegende Erfindung betrifft eine Mischvorrichtung für mindestens zwei Kartuschen mit zähflüssigem oder pastösem Inhalt und ein Verfahren zu deren Herstellung. The present invention relates to a mixing device for at least two cartridges with viscous or pasty content and a method for their production.

Kartuschen sind seit langem bekannt und finden dort häufig Venwendung, wo ein zähflüssiges oder pastöses Medium, wie beispielsweise Dichtungsmasse oder Klebstoff, bereitgehalten und abgegeben werden muss. Die Abgabe des Mediums geschieht dadurch, dass, meist nach Entfernung des Bodens der Kartusche, ein Kolben unter Druckwirkung in die Kartusche eingeführt wird und dadurch das in dieser enthaltene Medium durch eine dem Boden gegenüberliegende Düse abgegeben wird. Cartridges have been known for a long time and are often used where a viscous or pasty medium, such as sealing compound or adhesive, has to be kept ready and dispensed. The medium is dispensed by the fact that, usually after removing the base of the cartridge, a plunger is inserted into the cartridge under pressure and the medium contained in the cartridge is thereby dispensed through a nozzle opposite the base.

Probleme ergeben sich dort, wo der Inhalt zweier oder mehrerer Kartuschen gleichzeitig abgebeben und vermischt werden soll, wie dies beispielsweise bei Mehrkomponentenklebern der Fall ist. Mischvorrichtungen für zähflüssige oder pastose Medien sind zwar für ortsfeste Anlagen in der Industrie bekannt, es werden aber dort an die Mischvorrichtungen andere Anforderungen gestellt, zumal diese meistens zumindest während eines Arbeitstages in kontinuierlichem Betrieb sind. Mischvorrichtungen für Kartuschen müssen in erster Linie möglichst kostengünstig angeboten werden können, da sie insbesondere im erwähnten Anwendungsfall, bei welchem die Bestandteile von Mehr-komponentenklebern miteinander vermischt abgegeben werden sollen, als Wegwerfartikel betrachtet werden müssen. Problems arise where the contents of two or more cartridges are to be dispensed and mixed at the same time, as is the case with multi-component adhesives, for example. Mixing devices for viscous or pasty media are known for stationary plants in industry, but there are other requirements placed on the mixing devices, especially since these are usually in continuous operation at least during one working day. Mixing devices for cartridges must first of all be offered as inexpensively as possible, since they must be regarded as disposable items, in particular in the application mentioned, in which the components of multi-component adhesives are to be mixed with one another.

Obwohl schon Versuche mit Mischvorrichtungen für zwei Kartuschen unternommen wurden, sind bisher keine solche Vorrichtungen auf dem Markt erhältlich, da es nicht gelungen ist, die Anforderungen hinsichtlich der Qualität bei gleichzeitiger kostengünstiger Herstellung zu erfüllen. Although attempts have already been made with mixing devices for two cartridges, no such devices have been available on the market to date since it has not been possible to meet the quality requirements while at the same time being inexpensive to produce.

Eine solche Mischvorrichtung besteht im wesentlichen aus den Zuleitungen, die mit den Kartuschen-Öffnungen verbunden werden, welche Zuleitungen ihrerseits in den Mischkopf führen, der seinerseits in eine Abgabe-Düse mündet. Die Zuleitungen sind dabei so gebogen, dass sie mit den zwei parallel nebeneinander liegenden Kartuschen verbunden werden können. Um eine kostengünstige Herstellung in grösseren Serien zu ermöglichen, sollten diese Teile sowie gegebenenfalls sonstige weitere Teile, wie beispielsweise mechanische Mischhilfen im Mischkopf, aus Kunststoff hergestellt werden. Hier ergeben sich insbesondere bei'den gebogenen Zuleitungen insofern Schwierigkeiten, dass diese aus zwei Längshälften vorfabriziert werden müssen und diese beiden Hälften dann zur fertigen Leitung zusam-mengeschweisst werden. Durch das Zusammen-schweissen der beiden Längshälften einer Leitung wird ein Teil des Kunststoffes, insbesondere der Schweissraupe, zu beiden Seiten der Leitungswände zu einem Wulst herausgedrückt, welcher zwar aussen an der Leitung, wenn auch durch zusätzlichen Aufwand entfernt werden kann, jedoch innen in der Leitung verbleibt und dort zu einer Querschnittsverengung derselben führt. Besonders unangenehm ist dabei, dass diese Querschnittsverengungen sehr unregelmässig sind und deren Aus-mass der Leitung von aussen nicht angesehen werden kann. Solche unkontrollierbaren Querschnittsverengungen können aber gerade bei Mischvorrichtungen, wo es auf die genau dosierte Abgabe der zu mischenden Medien ankommt, nicht hingenommen werden. Die einzige sinnvolle Möglichkeit, das zuverlässige Funktionieren einer Mischvorrichtung zu gewährleisten, ist daher die, die Leitungen aus Metall herzustellen. Da die Mischvorrichtung im Betrieb einem gewissen Druck durch die in sie hineingepressten Medien ausgesetzt ist, ist es unvermeidbar, dass die Leitungen sowie die Teile des meist mehrteiligen Mischkopfes, vorzugsweise durch Verschrauben, fest miteinander verbunden werden. Insgesamt kann festgestellt werden, dass eine Mischvorrichtung, welche den qualitativen Anforderungen genügt, in der Herstellung für ein Wegwerfcrodukt viel zu teuer ist und daher letztlich nicht angeboten werden und Verwendung finden kann. Such a mixing device essentially consists of the feed lines which are connected to the cartridge openings, which feed lines in turn lead into the mixing head, which in turn opens into a dispensing nozzle. The supply lines are bent so that they can be connected to the two cartridges lying next to each other in parallel. In order to enable inexpensive production in larger series, these parts and, if appropriate, other further parts, such as mechanical mixing aids in the mixing head, should be made of plastic. Difficulties arise in particular in the case of the bent supply lines in that they have to be prefabricated from two longitudinal halves and these two halves are then welded together to form the finished line. By welding the two longitudinal halves of a line together, part of the plastic, in particular the welding bead, is pressed out on both sides of the line walls to form a bulge, which may be on the outside of the line, but can be removed by additional effort, but on the inside Line remains and there leads to a cross-sectional narrowing of the same. It is particularly unpleasant that these cross-sectional constrictions are very irregular and the extent of the line cannot be viewed from the outside. However, such uncontrollable narrowing of the cross-section cannot be accepted, particularly in the case of mixing devices, in which the precisely metered delivery of the media to be mixed is important. The only sensible way to ensure the reliable functioning of a mixing device is therefore to manufacture the lines from metal. Since the mixing device is exposed to a certain pressure during operation due to the media pressed into it, it is inevitable that the lines and the parts of the usually multi-part mixing head are firmly connected to one another, preferably by screwing. Overall, it can be stated that a mixing device which meets the qualitative requirements is far too expensive to manufacture for a disposable product and therefore ultimately cannot be offered and can be used.

Die Erfindung bezweckt, eine Mischvorrichtung für zwei oder mehrere Kartuschen zu schaffen, die einerseits zuverlässig arbeitet und anderseits auf einfache und kostengünstige Weise hergestellt werden kann. The invention aims to provide a mixing device for two or more cartridges which on the one hand works reliably and on the other hand can be manufactured in a simple and inexpensive manner.

Die erfindungsgemässe Mischvorrichtung entspricht den kennzeichnenden Merkmalen des Patentanspruchs 1, und das Verfahren zu seiner Herstellung entspricht den kennzeichnenden Merkmalen des Patentanspruchs 9. The mixing device according to the invention corresponds to the characterizing features of patent claim 1, and the method for its production corresponds to the characterizing features of patent claim 9.

Nachfolgend werden anhand der Zeichnungsfiguren drei Ausführungsbeispiele des Erfindungsgegenstandes beschrieben. Three exemplary embodiments of the subject matter of the invention are described below with reference to the drawing figures.

Fig. 1 zeigt ein erstes Ausführungsbeispiel, teilweise im Schnitt, 1 shows a first embodiment, partly in section,

Fig. 2 zeigt ein zweites Ausführungsbeispiel, Fig. 3 zeigt ein drittes Ausführungsbeispiel, Fig. 4 zeigt das Ausführungsbeispiel nach den Fig. 1 und 2 in Pfeilrichtung A gesehen, 2 shows a second exemplary embodiment, FIG. 3 shows a third exemplary embodiment, FIG. 4 shows the exemplary embodiment according to FIGS. 1 and 2 viewed in the direction of arrow A,

Fig. 5 zeigt das Ausführungsbeispiel nach Fig. 3 in Pfeilrichtung A gesehen, und Fig. 5 shows the embodiment of FIG. 3 seen in the direction of arrow A, and

Fig. 6 zeigt das Ausführungsbeispiel nach Fig. 3 in Pfeilrichtung A gesehen in unverschweisstem Zustand. Fig. 6 shows the embodiment of FIG. 3 seen in the direction of arrow A in the unwelded state.

Die Mischvorrichtung nach den Figuren 1 und 4 entspricht der einfachsten Ausführung. Der Mischkopf 1 und die beiden Zuleitungen 2 und 3 bestehen zusammen aus zwei Halbschalen 4 und 5, welche Halbschalen 4 und 5 an ihren nach aussen erweiterten Längsrändern 6 kraftschlüssig und dicht miteinander verbunden sind und so zusammen eine einstückige Mischvorrichtung bilden. Dabei sind die Längsränder 6 der Halbschalen 4 und 5 flanschartig ausgeformt. The mixing device according to Figures 1 and 4 corresponds to the simplest version. The mixing head 1 and the two feed lines 2 and 3 together consist of two half-shells 4 and 5, which half-shells 4 and 5 are non-positively and tightly connected to one another at their outwardly extended longitudinal edges 6 and thus together form a one-piece mixing device. The longitudinal edges 6 of the half-shells 4 and 5 are shaped like a flange.

Vorzugsweise besteht die Mischvorrichtung aus Kunststoff, wobei die Längsränder 6 oder Halbschalen 4 und 5 durch Schweissen miteinander verbunden werden. Zweckmässig werden dabei die Längsränder 6 mindestens einer Halbschale 4 oder 5 mit mindestens einer Schweissraupe 7 versehen, welche Schweissraupe 7 zum Verschweissen der Halbschalen erhitzt wird. The mixing device is preferably made of plastic, the longitudinal edges 6 or half-shells 4 and 5 being connected to one another by welding. The longitudinal edges 6 of at least one half-shell 4 or 5 are expediently provided with at least one welding bead 7, which welding bead 7 is heated for welding the half-shells.

Die Mischvorrichtung nach Figur 2 entspricht äusserlich derjenigen nach Figur 1; im Mischkopf sind jedoch als statische mechanische Mischhilfe Stege 8 vorgesehen. Ausserdem sind hier zwei Kartuschen 9 bzw. 10 dargestellt. Mit 9 ist eine Kartusche gezeigt, die gerade eingelegt wird, wobei ersichtlich ist, wie der abgeschrägte Rohransatz 11 der Zuleitung 2 die Verschluss-Membran 12 der Kartusche 9 aufstösst. Die Kartusche 10 ist hingegen schon eingelegt. Die gerundete obere Kante 13 der Abschrägung des Rohransatzes verhindert das Abreissen der Verschluss-Membran 12. Die Verschluss-Membran 12 wird demzufolge an einer Stelle vom Kartuschen-Hals sauber abgetrennt und umgebogen, wobei die Membran an der umgebogenen Stelle mit dem Kartuschen-Hals verbunden bleibt. Auf diese Weise wird wirksam verhindert, dass Reste der Membran wieder vor die Kartu-schen-Öffnung gelangen und diese verstopfen oder gar zusammen mit dem Medium ausgebracht werden. Ringnuten 14 dienen dem Einrasten eines Joches 15 einer nicht näher dargestellten Halterung einer Auspress-Pistole für die Kartuschen 9 und 10. Der Rohransatz 1 kann mit einem Dichtkonus 16 versehen sein. Externally, the mixing device according to FIG. 2 corresponds to that according to FIG. 1; however, webs 8 are provided in the mixing head as a static mechanical mixing aid. In addition, two cartridges 9 and 10 are shown here. 9 shows a cartridge which is just being inserted, it being possible to see how the beveled tube extension 11 of the feed line 2 pushes open the closure membrane 12 of the cartridge 9. The cartridge 10, however, is already inserted. The rounded upper edge 13 of the bevel of the tube attachment prevents the closure membrane 12 from tearing off. The closure membrane 12 is consequently cleanly separated and bent over at one point from the cartridge neck, the membrane being connected to the cartridge neck at the bent point remains. In this way, it is effectively prevented that remnants of the membrane get back in front of the cartridge opening and block it or even be brought out together with the medium. Ring grooves 14 are used to snap a yoke 15 into a holder, not shown, for a squeeze gun for cartridges 9 and 10. The tube extension 1 can be provided with a sealing cone 16.

In den Figuren 3 und 5 ist ein drittes Ausführungsbeispiel der Mischvorrichtung dargestellt, mit einer antreibbaren Mischschnecke 17. Der Mischkopf 1 mit der Düse wird hier separat hergestellt, worauf die Mischschnecke 17 eingeschoben und der Mischkopf 1 in die beiden Halbschalen 4 und 5 eingelegt wird, welche hier nur das Zuleitungsteil bilden, mit den Zuleitungen 2 und 3. Durch eine Öffnung ragen Mitnehmernocken 18 nach hinten aus dem Mischkopf, welche den Antrieb der Mischschnecke 17 mittels einer an der Auspress-Pistole angeordneten Drehspindel ermöglichen. Die Auspress-Pistole wird dabei vorzugsweise so gestaltet, dass die Mischschnecken-Drehspindel zusammen mit den beiden Kolben, welche die Medien aus den Kartuschen 9 und 10 pressen angetrieben wird. FIGS. 3 and 5 show a third exemplary embodiment of the mixing device, with a drivable mixing screw 17. The mixing head 1 with the nozzle is manufactured separately here, whereupon the mixing screw 17 is inserted and the mixing head 1 is inserted into the two half-shells 4 and 5, which here only form the supply line part, with the supply lines 2 and 3. Through an opening, driver cams 18 protrude rearward from the mixing head, which enable the mixing screw 17 to be driven by means of a rotating spindle arranged on the dispensing gun. The squeeze gun is preferably designed so that the mixing screw rotating spindle is driven together with the two pistons which press the media out of the cartridges 9 and 10.

In Figur 6 ist ebenfalls die vorgehend beschriebene Mischvorrichtung dargestellt, wobei die beiden Halbschalen 4 und 5 im noch unverschweissten Zustand gezeigt werden. Auf der unteren Halbschale 5 sind die Schweissraupen 7 ersichtlich. FIG. 6 also shows the mixing device described above, the two half-shells 4 and 5 being shown in the still unsealed condition. The welding beads 7 can be seen on the lower half-shell 5.

Selbstverständlich kann mit der erfindungsge-mässen Mischvorrichtung nicht nur im Verhältnis 50:50 gemischt werden, es sind vielmehr auch andere Mischverhältnisse wie 60:40 oder 70:30 denkbar. Dabei könnten die Zuleitungen auch mit unterschiedlichen Querschnitten ausgelegt werden. Of course, the mixing device according to the invention can not only be mixed in a ratio of 50:50, but other mixing ratios such as 60:40 or 70:30 are also conceivable. The supply lines could also be designed with different cross sections.
