Such means make possible a simple and secure alignment of the mixer on the cartridge. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zum gerichteten Befestigen eines Mischers an eine Kartusche sowie auf eine Kartusche, insbesondere Mehrfach-Kartusche, und Mischer zur Ausführung des Verfahrens. Es kann aus verschiedenen Gründen von Vorteil sein, den Mischer in einer bestimmten Orientierung an der Kartusche zu befestigen. So wenn zum Beispiel am Mischer-Auslassende Mittel vorgesehen sind, um dem herausgepressten Materialstrang eine besondere Form oder Lage, beispielsweise ein Band oder eine Dreiecksraupe, zu geben, ist es von Vorteil, die Orientierung des Mischers an der Kartusche genau zu definieren.The present invention relates to a method for the directional fastening of a mixer to a cartridge and to a cartridge, in particular a multi-cartridge, and mixer for carrying out the method. It can be advantageous for various reasons to attach the mixer to the cartridge in a certain orientation. So if, for example, means are provided at the mixer outlet end to give the extruded material strand a special shape or position, for example a band or a triangular bead, it is advantageous to precisely define the orientation of the mixer on the cartridge.

Ein statischer Mischer, der in einer bestimmten Lage an einer Doppel-Kartusche befestigbar ist, wird in der US-A-4 538 920 beschrieben. Die bestimmte Lage des Mischers an der Kartusche wird durch einen Bajonettverschluss erreicht, der eine etwa 90° Grad Schwenkung des Mischers im Flansch der Kartusche bedingt.A static mixer which can be attached in a certain position to a double cartridge is described in US-A-4,538,920. The specific position of the mixer on the cartridge is achieved by a bayonet lock, which causes the mixer to pivot about 90 ° in the flange of the cartridge.

Aus der EP-B-232 733 ist ein Mischer bekannt, der mittels Bajonett-Verschluss an einer Doppel-Kartusche befestigbar ist.From EP-B-232 733 a mixer is known which can be attached to a double cartridge by means of a bayonet catch.

Es ist davon ausgehend Aufgabe der vorliegenden Erfindung ein Verfahren zum gerichteten Befestigen des Mischers an eine Kartusche sowie Mittel zur Durchführung des Verfahrens anzugeben, die nicht auf die Befestigung mittels Bajonettverschluss beschränkt sind sondern allgemein anwendbar sind. Diese Aufgabe wird mit dem Verfahren gemäss Anspruch 1 und den Mitteln gemäss den weiteren unabhängigen Ansprüchen gelöst.Based on this, the object of the present invention is to specify a method for the directional fastening of the mixer to a cartridge and means for carrying out the method which are not restricted to fastening by means of a bayonet lock but are generally applicable. This object is achieved with the method according to claim 1 and the means according to the further independent claims.

Es kann ausserdem von Vorteil sein, wenn das aus Wendeln bestehende Mischerelement, beziehungsweise dessen Eingang, genau bezüglich dem Auslassende der Kartusche ausgerichtet ist, um ein optimaleres Durchmischen der Substanzen im Mischer zu erreichen. Dies ist besonders bei Doppel- oder Mehrfach-Kartuschen der Fall, bei welchen mehrere Komponenten miteinander vermischt werden müssen. Solche Ausrichtmittel, die in den beiden oben genannten Druckschriften als wesentlicher Bestandteil der jeweiligen Erfindung genannt sind, sind in den abhängigen Ansprüchen 6 und 7 angegeben, um ein Ausrichten aller zum Austragen wesentlicher Teile zu ermöglichen.It can also be of advantage if the mixer element, or its entrance, which is made up of coils, is aligned precisely with respect to the outlet end of the cartridge in order to achieve an optimal mixing of the substances in the mixer. This is particularly the case with double or multiple cartridges, in which several components have to be mixed together. Such alignment means, which are mentioned in the two above-mentioned documents as an essential part of the respective invention, are specified in the dependent claims 6 and 7 in order to enable alignment of all parts essential for the discharge.

Die Erfindung wird im folgenden anhand einer Zeichnung von Ausführungsbeispielen näher erläutert.

  • Figur 1 zeigt das kartuschenseitige Ende eines Mischergehäuses mit erfindungsgemässen Ausrichtmitteln,
  • Figur 2 zeigt das Auslassende einer zugehörigen Doppel-Kartusche mit zu den Mitteln am Mischergehäuse komplementären Ausrichtmitteln,
  • Figur 3 zeigt eine erste Ausführungsvariante mit Ausrichtmitteln am Mischergehäuse,
  • Figur 4 zeigt eine zweite Ausführungsvariante mit Ausrichtmitteln am Mischerelement,
  • Figur 5 zeigt eine Variante eines Auslassendes einer Doppelkartusche,
  • Figur 6 zeigt ein Mischerelement und ein Mischergehäuse vor dem Zusammenbau, und
  • Figur 7 zeigt ein weiteres Ausführungsbeispiel von Ausrichtmitteln am Mischergehäuse und an der Kartusche.
The invention is explained in more detail below with reference to a drawing of exemplary embodiments.
  • FIG. 1 shows the end of a mixer housing on the cartridge side with alignment means according to the invention,
  • FIG. 2 shows the outlet end of an associated double cartridge with alignment means which are complementary to the means on the mixer housing,
  • FIG. 3 shows a first embodiment variant with alignment means on the mixer housing,
  • FIG. 4 shows a second embodiment variant with alignment means on the mixer element,
  • FIG. 5 shows a variant of an outlet end of a double cartridge,
  • FIG. 6 shows a mixer element and a mixer housing before assembly, and
  • FIG. 7 shows a further exemplary embodiment of alignment means on the mixer housing and on the cartridge.

In Figur 1 erkennt man eines der erfindungsgemässen Ausrichtmittel an einem Mischergehäuse 16, mindestens eine Leiste 15. Diese Leiste arbeitet mit einer Nut 11 im Gewinde 12 zusammen, das auf dem Auslassstutzen 13 einer Doppelkartusche mit den zwei Vorratszylindern 17 und 18 angebracht ist. Falls am Mischergehäuse zwei Leisten 15, 15a vorgesehen sind, müssen im Gewinde 12 zwei Nuten angebracht werden. Dabei ist klar, dass nur eine Leiste und eine Nut eine eindeutige Stellung des Mischergehäuses bewirkt, während zwei Leisten und zwei Nuten zwei um 180° Grad verdrehte Stellungen ermöglichen. Der Stutzen 13 muss nicht notwendigerweise mit einem Gewinde versehen sein, so dass dann jede Nut im Hals eingelassen ist.In FIG. 1, one of the aligning means according to the invention can be seen on a mixer housing 16, at least one bar 15. This bar works together with a groove 11 in the thread 12, which is attached to the outlet nozzle 13 of a double cartridge with the two supply cylinders 17 and 18. If two strips 15, 15a are provided on the mixer housing, two grooves must be made in the thread 12. It is clear that only one ledge and one groove result in a clear position of the mixer housing, while two ledges and two grooves enable two positions rotated by 180 °. The connector 13 does not necessarily have to be provided with a thread, so that each groove is then embedded in the neck.

In Figur 7 ist ein weiteres Ausführungsbeispiel gezeigt, in dem am Auslassstutzen 29 einer Doppelkartusche zwischen dem Gewinde 26 und dem Ende ein Nocken 30 angebracht ist, der in einen entsprechenden Einschnitt 28 am Mischergehäuse 27 greift. Wie aus der Zeichnung hervorgeht, erstreckt sich der Nocken nicht bis zum äusseren Rand, damit dieser vollständig dichtend in den Absatz beim Uebergang zwischen dem zylindrischen und konischen Teil des Mischergehäuses greifen kann. Entsprechend den Ausrichtmitteln mit Leiste und Nut können auch zwei Nocken am Kartuschenstutzen und zwei Einschnitte am Mischergehäuse angeordnet sein, um anstatt ein eindeutiges Ausrichten zwei Stellungen zu ermöglichen. Auch hier ist das Gewinde 26 nicht immer notwendig, um den Mischer an der Kartusche zu befestigen.A further exemplary embodiment is shown in FIG. 7, in which a cam 30 is attached to the outlet connection 29 of a double cartridge between the thread 26 and the end and engages in a corresponding incision 28 on the mixer housing 27. As can be seen from the drawing, the cam does not extend to the outer edge, so that it can grip completely in the shoulder at the transition between the cylindrical and conical part of the mixer housing. Corresponding to the alignment means with bar and groove, two cams can also be arranged on the cartridge socket and two incisions on the mixer housing in order to enable two positions instead of unambiguous alignment. Again, the thread 26 is not always necessary to attach the mixer to the cartridge.

Bei diesen Ausführungsbeispielen wird nur das Mischergehäuse bezüglich der Kartusche ausgerichtet. Dies ist auch bei der Ausführungsvariante gemäss Figur 3 der Fall. An der Innenwand des Mischergehäuses 20 ist eine oder sind zwei Führung(en) 19 vorgesehen, in die je eine Seite einer entsprechend ausgebildeten Trennwand des Auslassstutzens einer Doppelkartusche greift, wobei die Tennwand beispielsweise wie die Trennwand 21 der Kartusche 22 von Figur 5 ausgebildet ist, die zwei Vorratszylinder 23 und 24 aufweist. In diesem Falle ist die Nut 25 am Gewinde 26 jedoch nicht notwendig. Die beiden Doppelkartuschen 17, 18 und 22 unterscheiden sich dadurch, dass die Vorratszylinder 17, 18 nicht den gleichen Querschnitt haben.In these exemplary embodiments, only the mixer housing is aligned with respect to the cartridge. This is also the case with the embodiment variant according to FIG. 3. There is one or two on the inner wall of the mixer housing 20 Guide (s) 19 are provided, into each of which one side of a correspondingly designed partition wall of the outlet port of a double cartridge engages, the partition wall being designed, for example, like the partition wall 21 of the cartridge 22 from FIG. 5, which has two storage cylinders 23 and 24. In this case, the groove 25 on the thread 26 is not necessary. The two double cartridges 17, 18 and 22 differ in that the supply cylinders 17, 18 do not have the same cross section.

Bei dieser Art von Ausrichten geht es vor allem darum, das Mischergehäuse, bzw. sein Auslassende, in einer eindeutigen Stellung oder in zwei eindeutigen Stellungen auszurichten, falls das Auslassende eine bestimmte Konfiguration aufweist, beispielsweise breiter als hoch oder dreieckig ausgebildet ist und somit in einer bestimmten Orientierung angewendet wird.This type of alignment is primarily about aligning the mixer housing, or its outlet end, in one unambiguous position or in two unambiguous positions if the outlet end has a specific configuration, for example wider than tall or triangular and thus in one certain orientation is applied.

Es ist bei vielen Anwendungen von Vorteil, das Mischerelement, bzw. dessen Eingangsteil, genau senkrecht zur Trennwand der Kartusche auszurichten, um eine optimalere Vermischung der Komponenten zu erreichen. In Figur 4 erkennt man den Eingangsteil eines Mischerelementes 1, das in ein Mischergehäuse, beispielsweise gemäss Figur 1, jedoch ohne Leisten, einsetzbar ist. Das Mischerelement 1 besteht aus einer Anzahl von Mischwendeln 3, die senkrecht zueinander angeordnet sind. Die erste Mischwendel 3A am Eingang des Mischers weist eine verlängerte Wand 4 auf, die einen Schlitz 5 besitzt. Beim Schlitz kann die Wand Führungsleisten 6 aufweisen.In many applications it is advantageous to align the mixer element or its input part exactly perpendicular to the partition of the cartridge in order to achieve a more optimal mixing of the components. 4 shows the input part of a mixer element 1, which can be inserted into a mixer housing, for example according to FIG. 1, but without strips. The mixer element 1 consists of a number of mixing helices 3 which are arranged perpendicular to one another. The first mixing coil 3A at the inlet of the mixer has an elongated wall 4 which has a slot 5. In the slot, the wall can have guide strips 6.

Bei der Verwendung an Doppel-Kartuschen mit Vorratszylindern mit einem stark von 1:1 abweichenden Volumen- bzw. Querschnittsverhältnis kann die verlängerte Wand der ersten Mischwendel beim Schlitzende auf einer Seite, z.B. 4a, weggelassen werden.When using double cartridges with storage cylinders with a volume or cross-sectional ratio that deviates greatly from 1: 1, the extended wall of the first mixing spiral at the end of the slot on one side, for example 4a, can be omitted.

Beim Aufsetzen eines solchen Mischers auf beispielsweise eine Kartusche wie gemäss Figur 5 greift die Trennwand 21 der Kartusche in den Schlitz 5 des Mischerelementes, so dass der Mischer in zwei Stellungen ausrichtbar ist. Um eine eindeutige Stellung festzulegen, ist eine Leiste 15 geeigneter. Bei der Ausrichtung mit den Mitteln gemäss Figur 4 kommt es bei diesem Ausführungsbeispiel vor allem darauf an, dass der Eingang der Mischwendel genau senkrecht zur Trennwand der Kartusche ausgerichtet ist. Beim Mischer gemäss EP-B-232 733 hingegen ist die Wand der ersten Mischwendel genau parallel zur Trennwand ausgerichtet.When such a mixer is placed on, for example, a cartridge as shown in FIG. 5, the partition 21 of the cartridge engages in the slot 5 of the mixer element, so that the mixer can be aligned in two positions. In order to establish a clear position, a bar 15 is more suitable. In the case of the alignment with the means according to FIG. 4, the important thing in this exemplary embodiment is that the inlet of the mixing spiral is aligned exactly perpendicular to the partition of the cartridge. In the mixer according to EP-B-232 733, however, the wall of the first mixing spiral is aligned exactly parallel to the partition.

Falls der Mischer, bzw. das Mischerelement und dort insbesondere das Eingangselement, lediglich in einer bestimmten Stellung bezüglich der Kartusche befestigt werden soll, würde es genügen, dass das Mischerelement irgendwie im Gehäuse eingeführt und befestigt ist, da die Ausrichtung des Mischers bezüglich der Kartusche durch das Mischerelement selbst erfolgt. In den eingangs erwähnten Fällen ist es jedoch vorteilhaft oder erforderlich, auch das Mischergehäuse bezüglich der Kartusche auszurichten, so dass dann das Mischerelement im Mischergehäuse in einer bestimmten Stellung befestigt sein muss.If the mixer, or the mixer element and there in particular the input element, is to be fastened only in a certain position with respect to the cartridge, it would suffice that the mixer element is somehow inserted and fastened in the housing, since the mixer aligns with the cartridge through the mixer element itself. In the cases mentioned at the outset, however, it is advantageous or necessary to also align the mixer housing with respect to the cartridge, so that the mixer element must then be fastened in a specific position in the mixer housing.

In beiden weiter oben erwähnten Druckschriften ist das Mischerelement im Gehäuse in definierter Weise eingesetzt. Dabei kann die Ausrichtung des Mischerelementes im Gehäuse beispielsweise gemäss den Figuren 6 und 7 durch zwei Nuten 8 erfolgen, die oben eine trichterförmige Erweiterung 9 aufweisen, um das Einschieben des Mischerelementes zu erleichtern. Dazu weist das Eingangsteil des Mischerelementes vorteilhafterweise einen Steg 7 auf, der etwas breiter ist als die Mischerwendeln und beidseits in die Nuten 8 greift.In both publications mentioned above, the mixer element is used in a defined manner in the housing. The mixer element can be aligned in the housing, for example according to FIGS. 6 and 7, by means of two grooves 8, which have a funnel-shaped extension 9 at the top, in order to facilitate the insertion of the mixer element. For this purpose, the input part of the mixer element advantageously has a web 7 which is somewhat wider than the mixer coils and engages in the grooves 8 on both sides.

Das Ausrichten des Mischers mit dem eindeutig positionierten Mischerelement gegenüber der Kartusche hat dann zusätzlich mit den oben beschriebenen Mitteln zu erfolgen, d.h. beispielsweise durch eine oder zwei Leisten am Mischergehäuse oder einen oder zwei Nocken am Kartuschenstutzen, durch die Verwendung eines Schlitzes oder Absatzes an der verlängerten Wand der ersten Mischwendel des Mischelementes, oder durch Führungen im Mischergehäuse. Bei letzterer Ausführung kann auf der einen Seite des Mischergehäuses eine Nut 8 und auf der anderen Seite eine Führung 19 angebracht sein.The alignment of the mixer with the clearly positioned mixer element in relation to the cartridge must then also be carried out using the means described above, i.e. For example, by one or two strips on the mixer housing or one or two cams on the cartridge socket, by using a slot or shoulder on the extended wall of the first mixing spiral of the mixing element, or by guides in the mixer housing. In the latter embodiment, a groove 8 and a guide 19 can be provided on one side of the mixer housing and on the other side.

Aus der Zeichnung und obiger Beschreibung geht hervor, dass das Mischerelement, respektive dessen Eingangsteil, das Mischergehäuse und die Auslassöffnungen der Kartusche, beziehungsweise die Trennwand zwischen den beiden Auslassöffnungen, jeweils in einer bestimmten Beziehung zueinander stehen. Zweckmässigerweise steht die Trennwand 14 zwischen den beiden Auslassöffnungen der Kartusche senkrecht zur Verbindungslinie zwischen den beiden Vorratszylindermittelpunkten und die Nut 11 am Gewinde des Auslassstutzens ist ebenfalls gleich ausgerichtet wie diese Trennwand, die ausserdem in der Verlängerung des Zwischenraums zwischen den beiden Vorratszylindern angeordnet ist. Der Schlitz 5 in der Wand 4 des Eingangsteils des Mischerelementes ist derart ausgebildet, dass er auf die Trennwand 14 des Auslassstutzens passt und die Wand 4 senkrecht zur Trennwand 14 zu liegen kommt, wenn der Mischer auf dem Auslassstutzen der Kartusche aufgesteckt ist. Dementsprechend ist die Leiste 10, oder beide Leisten 15, um 90° Grad versetzt zu den Nuten 8 im Mischergehäuse angeordnet, die die Seiten der Wand 4 des Mischerelementes aufnehmen. Sinngemäss gilt dies auch für die Nocken 30 und die Einschnitte 28.It can be seen from the drawing and the above description that the mixer element, or rather its input part, the mixer housing and the outlet openings of the cartridge, or the partition between the two outlet openings, each have a specific relationship to one another. Advantageously, the partition 14 between the two outlet openings of the cartridge is perpendicular to the connecting line between the two storage cylinder centers and the groove 11 on the thread of the outlet port is also aligned in the same way as this partition, which is also arranged in the extension of the space between the two storage cylinders. The slot 5 in the wall 4 of the input part of the mixer element is designed such that it fits on the partition 14 of the outlet connector and the wall 4 comes to lie perpendicular to the partition 14 when the mixer is plugged onto the outlet connector of the cartridge. Accordingly, the strip 10, or both strips 15, is arranged offset by 90 ° to the grooves 8 in the mixer housing, which receive the sides of the wall 4 of the mixer element. This also applies analogously to the cams 30 and the incisions 28.

Selbstverständlich kann bei paralleler Ausrichtung der ersten Mischwendelwand bezüglich der Trennwand des Kartuschenauslasses nicht der Schlitz oder Absatz am Eingangsteil als Ausrichtmittel verwendet werden, sondern es ist ein anderes Ausrichtmittel vorzusehen.Of course, if the first mixing spiral wall is aligned parallel to the partition of the cartridge outlet Do not use the slot or shoulder on the entrance part as an alignment device, but use another alignment device.

Die Leiste 10 kann nicht nur der Führung des Mischers auf der Kartusche, sondern auch als Markierung der Stellung des Mischergehäuses dienen, falls der Auslass des Mischers in einer bestimmten Stellung bezüglich der Kartusche ausgerichtet werden soll. Nach dem Aufstecken des Mischers auf die Kartusche wird dieser mit einer nicht gezeichneten Ueberwurfmutter gesichert, die auf das Gewinde 12 aufgeschraubt wird. Dies gilt auch für den Nocken 30 und den Einschnitt 28.The strip 10 can not only serve to guide the mixer on the cartridge, but also to mark the position of the mixer housing if the outlet of the mixer is to be aligned in a specific position with respect to the cartridge. After the mixer has been plugged onto the cartridge, it is secured with a union nut, not shown, which is screwed onto the thread 12. This also applies to the cam 30 and the incision 28.

Die Ausrichtmittel sind zwar am vorteilhaftesten bei der Verwendung von Mehrfach-, insbesondere Doppelkartuschen, jedoch nicht auf solche beschränkt. Ausserdem können die Vorratszylinder jeweils entweder gleiche oder voneinander verschiedene Volumina, bzw. Querschnitte aufweisen.The alignment means are most advantageous when using multiple cartridges, in particular double cartridges, but are not limited to such cartridges. In addition, the storage cylinders can each have either the same or different volumes or cross sections.
