Figur 1 zeigt die für den Mischerantrieb wichtigen Elemente, während die übrigen Teile, insbesondere der Antrieb für die Stössel und die Anordnung im Gehäuse, beispielsweise gemäss der europäischen Patentanmeldung Nr. 98810446.9 ausgebildet sein können.FIG. 1 shows the elements that are important for the mixer drive, while the remaining parts, especially the drive for the Tappet and the arrangement in the housing, for example according to European Patent Application No. 98810446.9 could be.
Figur 1 zeigt das Gerät 1 mit dem Geräteunterteil 2, der
Doppelkartusche 3, dem dynamischen Mischer 4 und der
Antriebswelle 5 mit Mitnehmer 6 für den dynamischen Mischer.
Um einen minimalen Fliessweg der Komponenten zu
gewährleisten, befindet sich der Mischer auf der
Verbindungsgeraden der Auslässe der Kartuschenbehälter und
zwischen der Verlängerung der Auslässe, bzw. zwischen der
gedachten Verlängerung der Kartuschenbehälter. Obwohl dies
die günstigste Lage für den Mischer ist, sind auch kleinere
Abweichungen davon möglich. Daraus folgt, dass je nach dem
Querschnitts-Verhältnis der Behälter der Kartuschen sich die
Lage des Mischers in Bezug auf den Geräteunterteil, bzw. der
Stösselachsen ändert.Figure 1 shows the device 1 with the
Der Rotor des dynamischen Mischers 4 wird von einem nicht
gezeichneten elektrischen Antrieb angetrieben, der über eine
Antriebswelle 7, Getrieberäder 8 und einem Zahnriemen 9 auf
die Mischerantriebswelle 5 wirkt. Die Mischerantriebswelle
ist über einen mehrfach gelagerten Bügel 10 und einen auf
der gleichen Achse 11 gelagerten Schwenkhebel 12 schwenkbar
angeordnet. Ausserdem ist der Mischer durch einen Bayonett-Ring
75 am Auslass der Kartusche befestigt, wobei dies auch
ein schraubbarer Ring sein kann.The rotor of the
Die Mischerantriebswelle ist antriebsseitig auf einer
Druckfeder 13 abgestützt und wird dadurch im Eingriff mit
dem Rotor des dynamischen Mischers gehalten. Die
Mischerwelle kann beispielsweise manuell gemäss EP-B-492 413
oder wie im vorliegenden Beispiel durch eine mit dem
Schlitten mitlaufende Schlittenbrücke 14 am Ende des
Rückhubes automatisch aus dem Mischer gezogen werden.The mixer drive shaft is on the drive
Wie später noch beschrieben, wird beim Einlegen von
Doppelkartuschen mit unterschiedlichen Verhältnissen der
Querschnitte die Mischerantriebswelle nach vorgängigem
Auswechseln der Führungsleisten für die Kartuschen-Positionierung
mittels der Krümmung der Kartuschenzylinder
jeweils automatisch in die richtige Position geschwenkt und
in Rasterungen 15 fixiert, womit das Gerät nach dem
Aufsetzen des dynamischen Mischers wieder betriebsbereit
ist.As described later, when inserting

Die Figuren 2 und 3 zeigen das Gerät gemäss Figur 1 von
oben, wobei in Figur 2 eine Doppelkartusche 16 mit zwei
zylindrischen Behältern 17 und 18 eingelegt ist, deren beide
Querschnittsflächen das Verhältnis 5:1 aufweisen. In Figur 3
ist im gleichen Geräteunterteil 2 die Doppelkartusche 3 von
Figur 1 eingelegt, die gleiche Behälter 19 und 20 mit dem
Querschnittsverhältnis 1:1 aufweist. Aus dem Vergleich der
Figuren 2 und 3 ist ersichtlich, dass einerseits die beiden
Austrag-Stössel 21 und 22 für alle Doppelkartuschen trotz
unterschiedlichen Querschnittsverhältnissen den gleichen
Achsenabstand A aufweisen, während die Antriebswelle 5, bzw.
der Mitnehmer, je nach Querschnittsverhältnis eine andere
Endlage einnimmt. Im vorliegenden Ausführungsbeispiel
erfolgt die Verlagerung durch eine Schwenkung parallel zu
den Behälterlängsachsen, wobei die beiden Endlagen des
Mitnehmers, entsprechend der Mittelachse Z des Mischers,
bzw. des Rotors, auf der Verbindungsgeraden der
Behälterauslässe liegen, wie dies insbesondere aus den
Figuren 4 und 5 hervorgeht.Figures 2 and 3 show the device according to Figure 1 of
above, with a
Es ist jedoch auch möglich, die Mischerwelle statt durch eine Verschwenkung durch eine Parallelführung zu verschieben, besonders bei Verwendung von mehr als zwei unterschiedlichen Doppelkartuschen, oder eine flexible Mischerantriebswelle vorzusehen, die ebenfalls eine Verlagerung des Mitnehmers ermöglicht. Die Verlagerung der Antriebswelle erfolgt jedoch stets derart, dass sich der Mitnehmer in der Endlage auf der Mittelachse Z des Mischerrotors befindet, um einen korrekten Antrieb zu gewährleisten.However, it is also possible to use the mixer shaft instead a pivoting through a parallel guide move, especially when using more than two different double cartridges, or a flexible To provide mixer drive shaft, which is also a Relocation of the driver enables. The relocation of the However, the drive shaft is always such that the Driver in the end position on the central axis Z of the Mixer rotor is located to ensure correct drive guarantee.
Aus der Verwendung desselben Gerätes 1 für Doppelkartuschen mit unterschiedlichen Querschnitten, d.h. mit verschiedenen geometrischen Abmessungen, ergibt sich die Forderung, die Doppelkartusche und den dynamischen Mischer in Bezug auf die Stössel und die Mischerantriebswelle auszurichten. Die exakte Führung und Positionierung der Kartuschen und damit auch des dynamischen Mischers geschieht - ausgehend von einem stets gleichen Gerät mit gleichem Geräteunterteil - erfindungsgemäss durch die Verwendung einer Kartuschenaufnahme mit auswechselbaren Führungsleisten, die den unterschiedlichen Durchmessern der Kartuschenbehälter angepasst sind und in die Kartuschenaufnahme eingesetzt werden, bzw. durch Ausrichtmittel, die an den Kartuschen angebracht sind.From the use of the same device 1 for double cartridges with different cross sections, i.e. with different geometric dimensions, the requirement arises Double cartridge and the dynamic mixer in terms of Align the plunger and the mixer drive shaft. The exact guidance and positioning of the cartridges and thus the dynamic mixer also happens - starting from always the same device with the same lower part - according to the invention by using a Cartridge holder with exchangeable guide strips that the different diameters of the cartridge containers are adapted and inserted into the cartridge holder be, or by aligning the cartridges are attached.
In den vorliegenden Beispielen gemäss Figuren 4 und 5 werden
zwei Doppelkartuschen mit einem Querschnittsverhältnis von
5:1 und 1:1 angegeben, doch ist es selbstverständlich, dass
dies auf weitere Querschnittsverhältnisse, beispielsweise
von 1:1 bis 10:1 übertragbar ist. Beim Vergleich der Figuren
4 und 5 erkennt man, dass die Kartuschenaufnahme 23 auf der
einen, hier rechten, Seite einen Krümmungsradius R24
aufweist, welcher der Krümmung des Behälters 19, also der
1:1 Kartusche 3, entspricht und der Krümmungsradius R25 der
linken Seite der Kartuschenaufnahme dem Krümmungsradius des
grösseren Behälters 18 der Doppelkartusche 16 entspricht.In the present examples according to FIGS. 4 and 5
two double cartridges with an aspect ratio of
5: 1 and 1: 1, but it goes without saying that
this on further cross-sectional relationships, for example
is transferable from 1: 1 to 10: 1. When comparing the figures
4 and 5 it can be seen that the
Daraus geht hervor, dass in den oben angegebenen
Querschnittsverhältnissen stets ein Behälter der
Doppelkartusche direkt auf der Kartuschenaufnahme aufliegt.
Der jeweils andere Behälter, hier 17 bzw. 20, ruht auf einer
Führungsleiste 26, bzw. 27, die sich auf der
Kartuschenaufnahme abstützt.It follows that in the above
Cross-sectional relationships always a container of
Double cartridge rests directly on the cartridge holder.
The other container, here 17 or 20, rests on one
Die Kartuschenaufnahme ist über zwei Arme 28 und 29 an den
Wänden 30 und 31 des Geräteunterteils 2 abgestützt, wobei
die Kartuschenaufnahme mit Längsnuten 32, 33 versehen ist,
in die ein entsprechender Schenkel 34 bzw. 35 der
Führungsleiste eingreift. Diese Schenkel sind derart
ausgelegt, bzw. kodiert, dass die Führungsleisten nicht
verkehrt eingelegt werden können. Der zweite Schenkel 36,
bzw. 37 der Führungsleiste 26 bzw. 27 stützt sich auf dem
gekrümmten Teil der Kartuschenaufnahme ab.
Selbstverständlich sind die Krümmungsradien R38 bzw. R39 der
Führungsleisten dieselben wie diejenigen der Behälter, hier
17 und 20, die sie aufnehmen.The cartridge holder is connected to the two
Das Gerät 1 weist ferner einen Gehäusedeckel 52 auf, der an
der oberen Wand 53 innen einen Ausrichtsteg 54 aufweist, der
im Mittelbereich angeordnet ist und einen abgeschrägten Teil
55 und einen horizontalen Teil 56 aufweist. Diese beiden
Teile dienen zur Niederhaltung und Ausrichtung entweder des
Verbindungsflansches 49 der 5:1 Kartusche 16, 116 oder 216,
siehe Figur 4 oder 9, oder des Verbindungsflansches 51 der
1:1-Kartusche, siehe Figur 5 oder 11.The device 1 also has a
Statt Führungsleisten zu verwenden ist es auch möglich, an den Kartuschen entsprechende Abstandhalter vorzusehen. In den Figuren 6 bis 11 sind solche Varianten dargestellt, wobei die Abstandhalter an der Behälterwand und/oder an den Auslässen oder an den Flanschen angeordnet sein können.Instead of using guide rails, it is also possible to use provide appropriate spacers for the cartridges. In FIGS. 6 to 11 show such variants, the spacers on the container wall and / or on the Outlets or can be arranged on the flanges.
In Figur 6 entspricht die Doppelkartusche 116 der
Doppelkartusche 16 von Figur 4 mit den beiden Behältern 117
und 18. Der grössere Behälter 18 ist derselbe wie in Figur 4
während die Wand des Behälters 117 mit kleinerem Querschnitt
zwei Abstandhalter 44 und 45 aufweist, die vorgesehen sind,
auf der Kartuschenaufnahme 23 aufzuliegen und der
Führungsleiste 26 entsprechen. Es ist auch denkbar, am
Behälter mit grösserem Querschnitt Abstandhalter vorzusehen. In Figure 6, the
In Figur 7 weist die Doppelkartusche 103, die der
Doppelkartusche 3 von Figur 5 entspricht, zwei gleiche
Behälter 19 und 120 auf, wobei die Wand des einen Behälters
120 zwei Abstandhalter 46 und 47 aufweist, die der
Führungsleiste 27 entsprechen, um auf der Kartuschenaufnahme
23 zu liegen. Bei einer anders gestalteten
Kartuschenaufnahme, z.B. für mehr als zwei unterschiedliche
Kartuschen, ist es auch denkbar, an beiden Behältern
Abstandhalter anzubringen.In Figure 7, the
In den Figuren 4 und 5, bzw. 6 und 7, sind ferner die
Doppelkartusche 16, bzw. 116, mit den Auslässen 40 und 41,
beispielsweise mit verschiedenen Auslass-Durchmessern, sowie
Doppelkartusche 3, bzw. 103, mit den beiden Auslässen 42 und
43, die den gleichen Durchmesser aufweisen, eingezeichnet
sowie die Mischerantriebswelle 5. Aus dem Vergleich der
Figuren 4 und 5 geht hervor, dass die Achse der
Antriebswelle 5 verschoben ist, da sie sich stets zwischen
den beiden Kartuschenbehältern, bzw. zwischen den beiden
Auslässen, befindet. Der Mischer und somit auch der
Mitnehmer befinden sich auf einer Achse Z, die in einem
Bereich auf der Verbindungsgeraden beider Auslässe und
zwischen der gedachten Verlängerung beider Behälter liegt.
In vorliegendem Beispiel liegen die Auslässe auf der
Verbindungsgeraden beider Behältermittelachsen.In Figures 4 and 5, or 6 and 7, are also the
In den Figure 8, 9 und 10, 11 ist dargestellt, dass die Abstützung der Kartusche im Gerät auch dadurch erfolgen kann, dass diese an den Auslässen auf dem Geräteunterteil abgestützt wird derart, dass unabhängig von dem Grössenverhältnis der Kartuschenbehälter diese stets in der richtigen Lage eingelegt und gehalten werden. Figures 8, 9 and 10, 11 show that the This also supports the cartridge in the device may be at the outlets on the bottom of the device is supported in such a way that regardless of the Size ratio of the cartridge container always in the be inserted and held in the correct position.
In den Figuren 8 und 9 ist eine im Gerät eingelegte 5:1-Kartusche
ähnlich wie in den Figuren 2 und 4 dargestellt.
Die Kartusche 216 weist zwei Behälter 17 und 18 auf. Der
Behälter 17 weist einen Auslass 57 und der Behälter 18 einen
Auslass 58 auf, wobei Auslass 57 Abstandhalter 59, 60 und
Auslass 58 Abstandhalter 61, 62 aufweisen, die eine ähnliche
Funktion wie die Abstandhalter 44-47 ausüben. Die
Abstandhalter 59-62 stützen sich auf eine Ausnehmung 63 in
der zum Mischer gerichteten Wand 64 des Geräteunterteils 2
und sind den Dimensionen dieser Ausnehmung angepasst. Im
stösselseitigen Bereich der Kartusche ist ein
Verbindungssteg 71 angeordnet, der derart gestaltet ist,
dass sich die Kartusche auf der Mischerantriebswelle 5
abstützen kann.FIGS. 8 and 9 show a 5: 1 cartridge inserted in the device
similar to that shown in FIGS. 2 and 4.
The
Analog zu den Figuren 8 und 9 ist in den Figuren 10 und 11
eine eingelegte 1:1-Kartusche dargestellt. Die Kartusche 203
weist die beiden Behälter 19 und 20 mit den Auslässen 65 und
66 auf. Die Auslässe sind mit Abstandhalter 67, 68, bzw. 69,
70 versehen, die sich auf der Ausnehmung 63 abstützen. Die
Kartusche weist ferner den Verbindungssteg 72 auf.Analogous to FIGS. 8 and 9 in FIGS. 10 and 11
an inserted 1: 1 cartridge is shown. The
Bei den Ausführungsbeispielen gemäss den Figuren 6-11 ist die Kartuschenaufnahme zur Abstützung der Kartuschen nicht notwendig und dient in diesem Fall ausschliesslich als Auffangwanne.In the exemplary embodiments according to FIGS. 6-11 the cartridge holder for supporting the cartridges is not necessary and in this case serves exclusively as Drip pan.
In den Schnitten der Figuren 12 und 13 ist ersichtlich, dass
die Einlässe 73 und 74 des Mischers 4 die gleiche Dimension
aufweisen, während bei den Kartuschen mit einem von 1:1
abweichenden Verhältnis die Auslässe 40, 57 der Behälter 17,
117 mit kleinerem Querschnitt einen kleineren Durchmesser
aufweisen als die Auslässe 41, 58 der Behälter 18 mit
grösserem Querschnitt. Bei den 1:1-Kartuschen sind beide
Auslässe gleich. Die unterschiedliche Dimensionierung der
Auslässe ist eine Anpassung an das unterschiedliche
Mischungsverhältnis.In the sections of FIGS. 12 and 13 it can be seen that
the
Die Durchmesser der Auslässe der Kartuschen sind derart dimensioniert, dass die Einlässe des Mischers entweder stets in die Auslässe der Behälter der 1:1-Kartuschen steckbar sind oder der eine Einlass in den Auslass des Behälters mit grösserem Querschnitt steckbar und der andere Einlass über den Auslass des Behälters mit kleinerem Querschnitt schiebbar ist. Bei allen Kartusche kann somit der Mischer in beiden um 180° gedrehten Lagen, d.h. ohne vorherige Orientierung, auf irgendeine angepassten Kartusche oder irgendein angepasstes Dosier- oder Austraggerät aufgeschoben werden. Ausserdem ist diese Kombination Mischereinlässe - Gerätauslässe nicht auf dynamische Mischer beschränkt.The diameter of the outlets of the cartridges are such dimensioned that the mixers' inlets either always can be inserted into the outlets of the containers of the 1: 1 cartridges or have an inlet in the outlet of the container larger cross section pluggable and the other inlet over the outlet of the container with a smaller cross section is slidable. With all cartridges, the mixer can be in both positions rotated by 180 °, i.e. without previous Orientation, on any customized cartridge or any adapted dosing or discharge device is pushed on become. In addition, this combination is mixer inlets - Device outlets are not limited to dynamic mixers.
Muss die Mischerwelle beim Wechsel des Austrag-Verhältnisses
seitlich verlagert werden, erfolgt dies automatisch durch
die Form der Behälter der neu eingelegten Kartusche, wobei
die Mischerwelle gleichzeitig in einer der Rasterungen 15
fixiert wird. Diese Verlagerung wird durch die Keilwirkung
jeweils einer Wand eines Behälters gewährleistet. Eine
Ausnehmung 48, bzw. 50 am ausgangsseitigen
Verbindungsflansch 49, bzw. 51 der Kartuschen dient dem
Durchlass und gegebenenfalls der Feinausrichtung der
Mischerantriebswelle. Gleichzeitig und zwangsläufig wird
dabei der Zahnriemenantrieb 9 der Mischerantriebswelle 5
ebenfalls geschwenkt. Must the mixer shaft when changing the discharge ratio
are moved laterally, this is done automatically by
the shape of the container of the newly inserted cartridge, where
the mixer shaft simultaneously in one of the
In vorliegendem Beispiel erlaubt der geringe Abstand zwischen den Kartuschenbehältern zwar den Durchtritt der Mischerantriebswelle, für deren Antrieb ist jedoch kein Platz vorhanden. Aus diesem Grunde befindet sich deren Antrieb im hinteren Geräteteil, ausserhalb des Kartuschen-und Schlittenbereichs.In the present example, the small distance allows between the cartridge containers the passage of the Mixer drive shaft, but there is no drive for it Space available. For this reason there is Drive in the rear part of the device, outside the cartridge and Sled area.
Natürlich können die Geräte in der gleichen Weise wie hier für die Querschnittsverhältnisse 1:1 und 5:1 beschrieben, auch für beliebige andere Verhältnisse ausgelegt werden. Würde beispielsweise ein Verhältnis von 2:1 benötigt, würde dies entweder eine andere Kartuschenaufnahme oder zwei Führungsleisten, bzw. entsprechende Abstandhalter erfordern, während die übrigen Teile des Gerätes mit dem gezeigten 1:1/5:1-Gerät identisch wären.Of course, the devices can be used in the same way as here described for the cross-section ratios 1: 1 and 5: 1, can also be designed for any other conditions. For example, if a ratio of 2: 1 was needed, either another cartridge holder or two Guide strips or corresponding spacers require while the remaining parts of the device with the shown 1: 1/5: 1 device would be identical.
In den vorliegenden Beispielen wurden Doppelkartuschen beschrieben, die nach Verwendung entsorgt werden müssen. Das gleiche Gerät mit den gleichen Teilen kann auch für Stützkartuschen mit Schlauchbeuteln verwendet werden, wobei gegebenenfalls die Stützkartuschen mit den selben Abstandhaltern versehen sein können wie die Doppelkartuschen.In the present examples, double cartridges were used that must be disposed of after use. The same device with the same parts can also for Support cartridges with tubular bags are used, whereby if necessary, the support cartridges with the same Spacers can be provided like that Double cartridges.
