Abstract

The twin-dispensing cartridge for two-component pastes has two supply cylinders (2, 3), having different diameters and in each case an outlet opening (4, 5), and a transition piece (7) which is mounted upstream of the supply cylinders and has a joint outlet for the components for connection to a mixer pipe (20) and dispensing channels (8, 9) adjoining the outlet openings. In order to avoid proportionally too little paste flowing out of the cylinder with a smaller cross-section when the closure is removed and at the beginning of the dispensing operation, the ratio of the volumes of the dispensing channels (8, 9) is selected such that it corresponds to the ratio of the volumes of the assigned supply cylinders (2, 3). In a preferred exemplary embodiment, the adaptation of the volume to the outlet opening (6) of the supply cylinder with the smaller volume (3) is brought about by an insert (21) in the corresponding dispensing channel (9). Both openings can be closed by a common closure. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf eine Doppeloder Mehrfachaustragkartusche für Zwei- oder Mehrkomponentenmassen, mit Vorratszylindern mit unterschiedlichen Volumen und je einer Austrittsöffnung und einem den Vorratszylindern vorgelagerten Uebergangsstück mit einem für die Komponenten gemeinsamen Auslass zum Anschluss eines Mischerrohres und an die Austrittsöffnungen anschliessende Austragkanäle. Eine Doppel-Austragkartusche mit diesen Merkmalen ist in der EP-A-294-672 des gleichen Anmelders beschrieben.The present invention relates to a double or multiple discharge cartridge for two- or multi-component masses, with storage cylinders with different volumes and each with an outlet opening and a transition piece upstream of the storage cylinders with an outlet common to the components for connecting a mixer tube and discharge channels connecting to the outlet openings. A double discharge cartridge with these features is described in EP-A-294-672 by the same applicant.

Bei dieser Kartusche und anderen auf dem Markt befindlichen Kartuschen wird die exakte Dosierung der Komponenten über den exakten Vorschub der Schubstangen und somit der Kolben vorgenommen, und es wird bei vorbekannten Kartuschen kein Gewicht auf den Oeffnungsquerschnitt der Austrittsöffnungen der Vorratszylinder, bzw. der Austragkanäle gelegt. Daher werden in der Regel die Austrittsöffnungen, unabhängig vom Querschnitt der Vorratszylinder aus spritztechnischen Gründen in etwa gleich bemessen und dies führt dazu, dass beim Beginn des Austragsvorganges, bzw. beim Entfernen des Verschlusses, mehr Masse aus der grösseren Kartusche in das Mischerrohr gelangt und somit ein gewisses Anfangsvolumen unbrauchbar ist und weggeworfen werden muss. Dies führt, abgesehen vom Materialverlust, zur unnötigen Verschmutzung durch in der Regel unaushärtbare Masse und zu Unsicherheit über das Mischen im richtigen Verhältnis.With this cartridge and other cartridges on the market, the exact dosing of the components is carried out via the exact feed of the push rods and thus the pistons, and no weight is placed on the opening cross-section of the outlet openings of the storage cylinders or the discharge channels in the case of known cartridges. Therefore, regardless of the cross-section of the supply cylinder, the outlet openings are generally dimensioned approximately the same for injection molding reasons, and this means that at the start of the discharge process or when the closure is removed, more mass gets into the mixer tube from the larger cartridge and thus a certain initial volume is unusable and must be discarded. Apart from the loss of material, this leads to unnecessary contamination due to the generally curable mass and to uncertainty about mixing in the correct ratio.

Es ist davon ausgehend Aufgabe der vorliegenden Erfindung eine Doppel-Austragskartusche anzugeben, die von Anfang an ein richtiges Mischverhältnis ermöglicht und somit eine Verwertung des gesamten Inhalts der Austragkartuschen gewährleistet, Die Lösung dieser Aufgabe sowie bevorzugte Ausführungsbeispiele dazu sind in den Ansprüchen definiert.On the basis of this, it is the object of the present invention to provide a double discharge cartridge which enables a correct mixing ratio from the outset and thus a utilization of the entire contents of the discharge cartridges guaranteed, The solution to this problem as well as preferred embodiments are defined in the claims.

Die Erfindung wird an Hand einer Zeichnung eines Ausführungsbeispiels erläutert.

  • Fig. 1 zeigt im Längsschnitt den erfindungswesentlichen Teil einer Doppel-Austragkartusche,
  • Fig. 2 zeigt einen Schnitt gemäss der Linie II-II in Fig. 1,
  • Fig. 3 zeigt einen weiteren Längsschnitt der Kartusche von Fig. 1 ohne Ueberwurfmutter,
  • Fig. 4 zeigt in einer Ansicht von Vorne die beiden Austrittsöffnungen der Vorratszylinder,
  • Fig. 5 zeigt einen Längsschnitt der Doppel-Austragkartusche im funktionsbereiten Zustand mit der Ueberwurfmutter und dem Mischerrohr und,
  • Fig. 6 zeigt in einer Sicht von Vorne die beiden Austrittskanäle.
The invention is explained with reference to a drawing of an embodiment.
  • 1 shows in longitudinal section the part of a double discharge cartridge essential to the invention,
  • FIG. 2 shows a section along the line II-II in FIG. 1,
  • 3 shows a further longitudinal section of the cartridge from FIG. 1 without a union nut,
  • 4 shows a front view of the two outlet openings of the storage cylinders,
  • 5 shows a longitudinal section of the double discharge cartridge in the operational state with the union nut and the mixer tube and,
  • 6 shows the two outlet channels in a view from the front.

Die Doppel-Austragkartusche 1 weist zwei Vorratszylinder 2 und 3 auf, wobei die querschnittsflächen der Vorratszylinder in vorliegendem Beispiel in einem Verhältnis von 10 zu 1 stehen. Wie aus Fig. 4 hervorgeht, sind die Austrittsöffnungen 4 und 5 der Zylinder 2 und 3 ungefähr gleich gross, d.h. sie haben ungefähr die gleiche Lichtweite. Da in vorbekannten Doppel-Kartuschen auch die Austragkanäle in etwa das gleiche Volumen aufnehmen können, braucht es nach dem Entfernen des Verschlusses viel länger, bis dieses Volumen aus der kleinen Kartusche aufgefüllt ist und somit gelangt in dieser Zeit viel mehr Masse aus der grossen Kartusche in den Mischer, wodurch das Mischverhältnis beider Komponenten nicht genau ist. In Fig. 6 sind die beiden Mündungen der Austragkanäle dargestellt und man erkennt, dass die Austrittsmündug 4 des Kanals des grossen Vorratszylinders 2 unverändert ist und mit der Lichtweite der Austrittsöffnung dieses Zylinders übereinstimmt, während die Mündung 6 einen querschnitt aufweist, der einem Zehntel des querschnittes des grossen Vorratszylinders entspricht. Es ist möglich, Austrittsöffnungen, respektive Austragkanäle mit diesen beiden Durchmessern direkt zu spritzen, doch führt dies besonders bei hohen Mischverhältnissen infolge grosser Materialanhäufungen zu Schwund- und anderen Problemen.The double discharge cartridge 1 has two storage cylinders 2 and 3, the cross-sectional areas of the storage cylinders in the present example being in a ratio of 10 to 1. As can be seen from FIG. 4, the outlet openings 4 and 5 of the cylinders 2 and 3 are approximately the same size, ie they have approximately the same light width. Since the discharge channels in previously known double cartridges can also hold approximately the same volume, it takes much longer after the closure has been removed for this volume to be filled up from the small cartridge and thus much more mass comes in from the large cartridge during this time the mixer, whereby the mixing ratio of the two components is not exact. In Fig. 6 the two mouths of the discharge channels are shown and it can be seen that the Outlet mouth 4 of the channel of the large storage cylinder 2 is unchanged and corresponds to the light width of the outlet opening of this cylinder, while the mouth 6 has a cross section which corresponds to a tenth of the cross section of the large storage cylinder. It is possible to spray outlet openings or discharge channels with these two diameters directly, but this leads to shrinkage and other problems, especially in the case of high mixing ratios as a result of large material accumulations.

Im folgenden wird anhand des Ausführungsbeispiels eine Lösung zur wirtschaftlichen Herstellung von Austragkanalmündungen im Verhältnis der Komponentenmassen, respektive Kartuschenquerschnitte erläutert. Wobei diese Lösung insbesondere bei querschnittsverhältnissen von grösser als 2:1 vorteilhaft ist. Die beiden Vorratszylinder 2 und 3 werden einstückig mit dem Uebergangstück 7 gespritzt. Wie aus den Figuren hervorgeht, sind die beiden Austrittsöffnungen 4 und 5, die in die beiden Austragkanäle 8 und 9 münden, in etwa gleich, wie für das Vehältnis 1:1 erforderlich.In the following, a solution for the economical production of discharge channel orifices in the ratio of the component masses or cartridge cross sections is explained using the exemplary embodiment. This solution is particularly advantageous in the case of cross-sectional ratios of greater than 2: 1. The two storage cylinders 2 and 3 are injection-molded in one piece with the transition piece 7. As can be seen from the figures, the two outlet openings 4 and 5, which open into the two discharge channels 8 and 9, are approximately the same as required for the vehicle 1: 1.

Die Mittelwand 10 des Uebergangstücks, die aus der Vereinigung der beiden Vorratszylinderwände 46 bzw. 47 hervorgeht, ragt über die zylindrische Wand 11 mit dem Gewinde 12 hervor, und ist um etwas zugespitzt. Aus den Figuren 1 oder 3 geht deutlich hervor, dass die beiden getrennten Wände sich erst nach dem Verschlussbereich, d.h. oberhalb der beiden Verschlussteile am Verschluss 32, vereinen, um die Mittelwand 10 zu ergeben. Dadurch wird eine Diffusion der verschiedenen Komponenten vor dem Mischen ausgeschlossen. Die Aussenwand 11 des Uebergangstücks mündet nicht direkt an den Stirnseiten 13 und 14 der Vorratszylinder sondern in einen Flansch 15, der über eine Uebergangstruktur 16 mit der Stirnseite der Vorratszylinder verbunden ist. Der Flansch und die Uebergangstruktur sind Anpassungsteile an die Austragsgeräte. In Fig. 1 oder 5 ist ferner eine Ueberwurfmutter 19 eingezeichnet, die unter anderem das Mischerrohr 20 am Uebergangsstück befestigt. Das Mischerrohr 20 ist an sich bekannt und kann beispielsweise wendelförmige Elemente enthalten, um eine Durchmischung der Komponenten zu erzielen.The central wall 10 of the transition piece, which emerges from the union of the two supply cylinder walls 46 and 47, protrudes beyond the cylindrical wall 11 with the thread 12 and is somewhat tapered. It can be clearly seen from FIGS. 1 or 3 that the two separate walls only unite after the closure region, ie above the two closure parts on the closure 32, in order to produce the middle wall 10. This prevents diffusion of the various components before mixing. The outer wall 11 of the transition piece does not open directly on the end faces 13 and 14 of the supply cylinder but in a flange 15 which is connected to the Front of the storage cylinder is connected. The flange and the transition structure are adaptation parts to the discharge devices. In Fig. 1 or 5, a union nut 19 is also drawn, which, among other things, attaches the mixer tube 20 to the transition piece. The mixer tube 20 is known per se and can, for example, contain helical elements in order to achieve thorough mixing of the components.

Das Verhältnis der Lichtweiten, d.h. der Mündungen 4 und 6 der Austragkanäle, wird durch einen Einsatz 21 bestimmt, der in der Austrittsöffnung 5 des kleineren Vorratszylinders 3 eingesteckt ist. Normalerweise enthält die Austrittsöffnung 4 des grösseren Zylinders keinen solchen Einsatz, denn sie kann jedesmal als Bezugsöffnung verwendet werden. Der Einsatz erstreckt sich über die ganze Länge des Uebergangstücks und schliesst oben mit seiner zugespitzten Stirnwand 22 bündig mit der Mittelwand 10 ab und weist an seinem anderen, vorratszylinderseitigen Ende an seiner der Innenwand des Uebergangstückes angepassten Aussenwand 23 eine Schulter 24 auf, die die Innenwand 25 der Stirnseite 14 des kleineren Vorratszylinder hintergreift, womit der Einsatz gesichert ist. Der untere Teil des Einsatzes, bei der Schulter 24, weist einen Schlitz 26 auf, um eine federnde Wirkung zu erzielen. Die der Mittelwand 10 zugewandte Seite 27 des Einsatzes weist zwei Absätze 28 und 29 auf, wobei der zweite, vorratszylinderseitige Absatz 29 an einem entsprechenden Absatz 30 aufliegt. Die beiden Absätze 30 und 44 werden durch die Oberseite von Flansch 15 gebildet, siehe Fig. 4.The ratio of the light widths, i.e. the mouths 4 and 6 of the discharge channels is determined by an insert 21 which is inserted in the outlet opening 5 of the smaller storage cylinder 3. Normally, the outlet opening 4 of the larger cylinder does not contain such an insert because it can be used as a reference opening each time. The insert extends over the entire length of the transition piece and ends at the top with its tapered end wall 22 flush with the middle wall 10 and, at its other end on the cylinder side, on its outer wall 23 adapted to the inner wall of the transition piece, has a shoulder 24 which connects the inner wall 25 engages behind the end face 14 of the smaller storage cylinder, whereby the insert is secured. The lower part of the insert, at the shoulder 24, has a slot 26 in order to achieve a resilient effect. The side 27 of the insert facing the middle wall 10 has two shoulders 28 and 29, the second shoulder 29 on the supply cylinder side resting on a corresponding shoulder 30. The two shoulders 30 and 44 are formed by the top of flange 15, see FIG. 4.

Der Einsatz 21 weist in seiner Mitte einen zylindrischen Einsatzkanal 31 auf, dessen Querschnittsverhältnis zum Austragskanal des grösseren Vorratszylinders das gleiche ist wie das Verhältnis des Querschnittes des kleineren Vorratszylinders zum grösseren.The insert 21 has in its center a cylindrical insert channel 31 whose cross-sectional ratio to the discharge channel of the larger supply cylinder is the same as the ratio of the cross-section of the smaller one Storage cylinder to the larger one.

Die beiden Oeffnungen werden durch einen Verschluss 32 verschlossen, wobei die Oeffnungen auf der Höhe der Innenwände der Stirnseiten der Vorratszylinder verschlossen werden. Der Verschluss 32 besteht aus einem stabförmigen Teil 33, dessen unteres, zylindrisches Ende 36 dem Einsatzkanal 31 angepasst ist, sowie aus einem Zapfenteil 34, der dem Austragkanal, respektive der Austrittsöffnung 4 des grösseren Zylinders 2, angepasst ist. Der unterste Teil des Zapfens 34 weist einen Hohlraum 38 auf, zur Vermeidung von Materialanhäufung.The two openings are closed by a closure 32, the openings being closed at the level of the inner walls of the end faces of the storage cylinders. The closure 32 consists of a rod-shaped part 33, the lower, cylindrical end 36 of which is adapted to the insert channel 31, and of a pin part 34 which is adapted to the discharge channel or the outlet opening 4 of the larger cylinder 2. The lowest part of the pin 34 has a cavity 38 in order to avoid material accumulation.

Der stabförmige Teil 33 und das Zapfenteil 34 werden nach oben je durch einen Absatz 39, bzw. Kragen 40, abgeschlossen, wobei sich diese beiden Teile im eingesetzten Zustand aüf dem oberen Abschluss der Aussenwand 11 des Uebergangstücks abstützen. Oberhalb des Absatzes, bzw. Kragen befindet sich je eine Rippe 45, auf die die Ueberwurfmutter 19 wirkt, um den Verschluss anzupressen. Der Absatz 39 läuft in einer entsprechenden Nut 41 in der abgeschrägten Stirnseite 22 des Einsatzes. Beide Verschlussteile sind über einen Kopf 35 miteinander verbunden und der ganze Verschluss ist einstückig gespritzt.The rod-shaped part 33 and the pin part 34 are closed at the top by a shoulder 39 or collar 40, these two parts being supported on the upper end of the outer wall 11 of the transition piece in the inserted state. Above the shoulder or collar there is a rib 45 on which the union nut 19 acts in order to press the closure. The shoulder 39 runs in a corresponding groove 41 in the beveled end face 22 of the insert. Both closure parts are connected to one another via a head 35 and the entire closure is injection-molded in one piece.

Bei dünnflüssigen Materialien kann es vorteilhaft, bzw. erforderlich sein, sowohl den stabförmigen Teil 33 als auch das Zapfenteil 34 oben mit je einer Dichtlippe 17, bzw. 18 zu versehen.In the case of low-viscosity materials, it can be advantageous or necessary to provide both the rod-shaped part 33 and the pin part 34 with a sealing lip 17 or 18 at the top.

Die innere Wand 42 des Zapfenteils 34, die entlang der Mittelwand 10 zu liegen kommt, weist einen Absatz 43 auf, der sich auf dem entsprechenden Absatz 44 von Flansch 15 abstützen kann. Durch die angegebenen Massnahmen kann ein sicherer und fester Verschluss gewährleistet werden.The inner wall 42 of the pin part 34, which comes to rest along the middle wall 10, has a shoulder 43 which can be supported on the corresponding shoulder 44 of the flange 15. The specified measures can ensure a secure and firm closure be guaranteed.

Nach dem Entfernen des Verschlusses wird das Mischerrohr 20 mittels der Uberwurfmutter 19 am Uebergangstück befestigt und die Doppelkartusche ist wie in Figur 5 dargestellt zum Austragen im richtigen Mischverhältnis bereit, ohne das Material weggeworfen werden muss.After the closure has been removed, the mixer tube 20 is fastened to the transition piece by means of the union nut 19 and the double cartridge is ready for dispensing in the correct mixing ratio, as shown in FIG. 5, without the material having to be thrown away.

Die Erfindung wurde zwar anhand einer Doppelaustragkartusche für Zweikomponentenmassen erläutert, doch können die Merkmale der Erfindung von jedem Fachmann für eine Mehrfachkartusche, d.h. mit mehr als zwei Vorratszylindern, und für Mehrkomponenten ausgeführt werden. Selbstverständlich kommen auch andere Querschnittsverhältnisse der Vorratszylinder als 10:1 in Frage.Although the invention has been explained with the aid of a double discharge cartridge for two-component compositions, the features of the invention can be used by any person skilled in the art for a multiple cartridge, i.e. with more than two storage cylinders, and for multi-components. Of course, cross-sectional ratios other than 10: 1 are also possible.

Bei den beschriebenen Beispielen wurde der Einfachheit halber von jeweils gleicher Länge der Austragkanäle einerseits und der Vorratszylinder andererseits ausgegangen, so dass jeweils deren Querschnittsflächen verglichen wurden. In der Tat handelt es sich darum, dass die Volumen der Austragkanäle im Verhältnis der Volumen der zugeordneten Vorratszylinder ausgeführt sein müssen.In the examples described, for the sake of simplicity, the same length of the discharge channels on the one hand and the storage cylinder on the other hand was assumed, so that their cross-sectional areas were compared. In fact, the volume of the discharge channels must be designed in relation to the volume of the assigned supply cylinder.
