Abstract

A two component mixt. is applied by means of a gun with two hydraulic cylinders (2) mounted side by side. The gun has an actuating lever (10) which controls a valve (16) so that hydraulic fluid is directed into the cylinders (2) and acts on the pistons (4). These pistons (4) are connected by rods to second pistons (8) which are pressed inside open ended cartridges (1) which contain the separate components. These cartridges (1) are clamped in housings (50) attached to the gun. Some of the substance from each cartridge is forced into a mixing chamber (37) where the two components are mixed by a rotor (40) actuated by the movement of the lever (10). The mixt. of the two components is then ejected through the gun nozzle. USE - Applying a two component mixture.

Description

Dosierpistolen für zwei Komponenten werden verwendet, wenn die beiden Komponenten erst bei der Verarbeitung zusammenkommen dürfen, da sie in sehr kurzer Zeit aushärten; Dispensing guns for two components are used when the two components must come together only during processing as they harden in a very short time; dies gilt beispielsweise für bestimmte Klebstoffe. This applies, for example, for certain adhesives.

Bekannte Dosierpistolen verwenden zwei parallel liegende Kartuschen, die durch zwei mechanisch angetriebene synchron laufende Kolben in eine gemeinsame statische Misch kammer mit Auslaufdüse entleert werden. Known dispensing guns use two parallel cartridges which are emptied by two mechanically driven synchronously running piston in a common static mixing chamber with outlet nozzle. Da das Mischungsverhältnis der beiden Komponenten normalerweise nicht 1 : 1 beträgt, wird die Kartusche mit dem kleineren Volumen mit einem entsprechend kleineren Durchmesser versehen. Since the mixing ratio of the two components not normally is 1: 1, the cartridge is provided with the smaller volume with a correspondingly smaller diameter. Die Mischkammer besteht aus einem meist konischen Rohr mit festangebrachten Prallkörpern, durch welches die beiden Komponenten gefördert werden. The mixing chamber consists of a generally conical barrel having a permanently attached baffles, which are conveyed by the two components. Um eine gute Mischung zu erzielen, müssen die Prallkörper oder Prallflächen sehr eng gestellt werden, so daß zum Durchströmen hohe Drücke erforderlich sind. In order to achieve a good mix, the baffle or baffles have to be very close together, so that high for flow pressures are required.

Das Gerät nach der vorliegenden Erfindung benutzt zwei gleich große, parallel zueinander liegende Kartuschen, welche durch zwei mit unterschiedlicher Geschwindigkeit laufende, hydraulisch betätigte Kolben in eine gemeinsame Mischkammer entleert werden. The device according to the present invention uses two equal, parallel to each other cartridges which are emptied by two running at different speeds, hydraulically actuated pistons in a common mixing chamber. Um eine gute Mischung der beiden Komponenten zu erzielen, wird in der Mischkammer ein Flügelrad durch die Betätigung des Handhebels über eine Verbin dungsstange in eine hin- und hergehende und drehende Bewegung versetzt. In order to achieve a good mix of the two components in the mixing chamber, an impeller by the operation of the hand lever via a Verbin is dung rod in a reciprocating and rotational movement added.

Fig. 1 zeigt einen Längsschnitt durch die Dosierpistole mit der gestrichelt gezeichneten Kartusche 1 für die Komponente mit dem größeren Mischungsanteil. Fig. 1 shows a longitudinal section through the dispensing gun with the dashed cartridge 1 for the component with the higher mixing ratio. Im Gehäuse 2 befindet sich das Zylinderrohr 3 mit dem Kolben 4 und der Dichtung 5 . In the housing 2, the cylinder tube 3 is connected to the piston 4 and the seal. 5 Die Kolbenstange 6 ist fest mit dem Kolben 4 verbunden und führt durch die Dichtung 7 aus dem Gehäuse 2 heraus und ist am anderen Ende mit der Druckplatte 8 versehen, welche in das offene Ende der Kar tusche 1 eingeführt ist. The piston rod 6 is rigidly connected to the piston 4 and leads out of the housing 2 through the gasket 7 and is provided at the other end with the pressure plate 8, which is inserted into the open end of the Kar mascara. 1 Das untere Ende des Gehäuses ist als Pistolengriff 9 ausge führt. The lower end of the housing is provided as a pistol grip 9 carries out. Der Handhebel 10 ist um die im Gehäuse 2 gelagerte Achse 11 schwenkbar. The hand lever 10 is pivotable about the axis mounted in the housing 2. 11 Der Stufenkol ben 12 ist im Gehäuse 2 verschiebbar ange ordnet und tritt durch die Dichtung 13 aus dem Gehäuse 2 aus und wird durch die Feder 14 in Richtung auf den Handhebel 10 gedrückt. The Stufenkol ben 12 is in the housing 2 slidably arranged and passes through the seal 13 from the housing 2 and is urged by the spring 14 in the direction of the hand lever 10 degrees. Der Hub des Stufenkolbens 12 wird durch den Anschlag 15 am Gehäuse begrenzt. The stroke of the stepped piston 12 is limited by the stop 15 on the housing. Der Steuer kolben 16 kann nur durch Herausdrücken des Handhebels 10 gegen die Wirkung der Feder 17 in das Gehäuse 2 gedrückt werden und verbindet dann die beiden Steuerbohrungen 18 und 19 miteinander. The control piston 16 can be pressed 10 against the action of the spring 17 into the housing 2 only by pushing out the hand lever and then connects the two control bores 18 and 19 with each other.

Das Innere des Gehäuses 2 ist restlos mit Hydraulikflüssigkeit gefüllt. The interior of the casing 2 is completely filled with hydraulic fluid. Um Volumen änderungen durch Austreten der Kolbenstangen aus dem Gehäuse 2 und durch Wärmedehnung auf zufangen, ist das Gehäuse 2 am oberen Ende durch eine elastische Membran 20 abgeschlossen. To volume changes by leakage of the piston rods from the housing 2, and due to thermal expansion on zufangen, the housing 2 is closed at the top by an elastic membrane 20th Diese Membran wird über die Platte 21 durch die Feder 22 in das Gehäuse hineinge drückt und hält die Hydraulikflüssigkeit stän dig unter einem geringen Überdruck. This membrane is in the housing presses hineinge over the plate 21 by the spring 22 and keeps the hydraulic fluid RESISTING dig under a slight overpressure. Die Membran 20 mit Platte 21 und Feder 22 wird durch einen Gehäusedeckel 23 vor Beschädigungen von außen geschützt. The membrane 20 with plate 21 and spring 22 is protected by a housing cover 23 from damage from the outside.

Der Steg 24 im Gehäuse 2 trennt die Druckseite 25 des Kolbens 4 von der drucklosen Seite 26 dieses Kolbens. The web 24 in the housing 2 separates the pressure side 25 of the piston 4 from the pressure-free side 26 of the piston.

Das Saugventil 27 besteht aus einem gerollten dünnen, elastischen, offenen Stahlblechring mit geringer Vorspannung, ähnlich einem Kolbenring an der Wand anliegend. The suction valve 27 is made of a rolled thin, flexible, open steel ring with the low bias, similar to a piston ring on the wall fitting. Das eine Ende 28 ist im Gehäuse befestigt, das lose Ende 29 liegt vor der Steuerbohrung 18 ( Fig. 3). The one end 28 is mounted in the housing, the free end 29 is located before the control bore 18 (Fig. 3).

Am Gelenkpunkt 32 des Handhebels 10 ist die Verbindungsstange 33 befestigt. At the articulation point 32 of the hand lever 10, the connecting rod 33 is fixed.

Das andere Ende 34 dieser Verbindungsstange ist gabelförmig ausgebildet und greift in den Hals 35 der Verschiebewelle 36 der Misch kammer 37 ein. The other end 34 of the connecting rod is fork-shaped and engages in the neck 35 of the sliding shaft 36 of the mixing chamber 37 a. In die Verschiebewelle 36 ist eine schräge Nute 38 eingearbeitet, welche sich mit einem in der Mischkammer 37 befestig ten Stift 39 im Eingriff befindet. In the sliding shaft 36 is an oblique groove 38 is incorporated, which is located with a befestig th in the mixing chamber 37 pin 39 is engaged.

Mit der Verschiebewelle 36 fest verbunden ist ein Flügelrad 40 . Fixedly connected to the sliding shaft 36 is an impeller 40th

Fig. 2 zeigt einen Teil-Längsschnitt durch die Dosierpistole mit der gestrichelt gezeich neten Kartusche 41 für die Komponente mit dem geringeren Mischungsanteil. Fig. 2 shows a partial longitudinal section through the dispensing gun with the dashed Drawn Neten cartridge 41 for the component having the lower mixing ratio. Hier wirkt der Handhebel 10 nicht mehr direkt auf den Kolben 42 , sondern unter Zwischenschaltung eines Hebels 43 . Here, the lever 10 no longer acts directly on the piston 42, but with the interposition of a lever 43rd Dieser Hebel sitzt mit seiner Bohrung auf dem Zapfen 44 des Exzenters 45 und wird durch die Feder 46 über den Kolben 47 mit seiner Nase 48 gegen den Handhebel 10 gedrückt. This lever is seated with its bore on the journal 44 of the eccentric 45 and is urged by the spring 46 over the piston 47 with its nose 48 against the hand lever 10 degrees. Der Exzenter 45 ist mit seiner Welle 49 drehbar im Gehäuse 2 gelagert und kann in jeder Lage fixiert werden. The eccentric 45 is mounted with its shaft 49 mounted in the housing 2 and can be fixed in any position.

In der gezeichneten Lage befindet sich die Nase 48 im geringsten Abstand von der Achse 11 des Handhebels 10 , der Kolben 47 macht den geringsten Hub. In the drawn situation the nose 48 is in the least distance from the axis 11 of the hand lever 10, the piston 47 makes the smallest stroke. Durch Drehung des Exzenters 45 um 180° wird der Hub des Kolbens 47 am größten. The stroke of the piston 47 becomes the largest, by rotation of the cam 45 by 180 °.

Fig. 3 zeigt einen Querschnitt durch die Dosierpistole und die Anordnung der Saugventile. Fig. 3 shows a cross section through the dispensing gun and the arrangement of the suction valves.

Fig. 4 zeigt eine Seitenansicht der Dosier pistole. Fig. 4 shows a side view of the dispensing gun. Die Abdeckhaube 50 kann über den Drehpunkt 51 nach oben geschwenkt werden, um die Kartuschen zu wechseln. The cover 50 can be pivoted about the pivot point 51 upwards to move the cartridge.

Fig. 5 zeigt die Vorderansicht der Dosierpistole. Fig. 5 shows the front view of the dispensing gun. 1 ist die strichpunktiert gezeichnete Kartusche für die Komponente mit dem größeren Mischungs anteil. 1 the dash-dotted line cartridge for the component with the higher proportion is Mix. 41 ist die strichpunktiert gezeichnete Kartusche für die Komponente mit dem geringeren Mischungsanteil. 41 is the dash-dotted line cartridge for the component having the lower mixing ratio.

Wirkungsweise operation

Die beiden Kartuschen 1 und 41 werden nach dem Öffnen durch Anschneiden der Gewindespitze in die Misch kammer 37 eingeschraubt und gemeinsam in die Do sierpistole eingelegt und durch die Abklappen der Abdeckhaube 50 fixiert. The two cartridges 1 and 41 are screwed to the opening by cutting the thread crest in the mixing chamber 37 and inserted together into the Do sierpistole and fixed by the folding down of the cover 50th Sollte die Druck platte 8 zu weit ausgefahren sein, kann durch Lüften (Herausdrücken) des Handhebels 10 der Steuerkolben 18 in das Gehäuse 2 gedrückt werden, wodurch eine Verbindung der Druckseite 25 mit der drucklosen Seite 26 über die Steuerbohrungen 17 und 18 erfolgt. Should the pressure be plate 8 extended too far, the control piston, by airing (pushing) of the hand lever 10 to be pressed into the housing 2 18, whereby a connection of the pressure side 25 to the non-pressure side 26 through the control bores. 17 and 18 Jetzt kann die Druckplatte 8 mit Kolbenstange 6 und Kolben 4 in das Gehäuse 2 verschoben werden. Now the pressure plate 8 with the piston rod 6 and the piston 4 can be moved into the housing. 2 Das gleiche gilt auch für die Druckplatte auf der Seite der Kartusche 41 für den geringeren Mischungsanteil. The same also applies to the pressure plate on the side of the cartridge 41 for the lower mixing ratio.

Durch die Betätigung des Handhebels 10 wird der Kolben 12 in das Gehäuse 2 gedrückt und ver drängt die Hydraulikflüssigkeit aus dem Raum 53 über die Bohrung 31 , das Druckventil 30 in den Druckraum 25 . By the actuation of the hand lever 10 the plunger is pushed into the housing 2 and ver 12 urges the hydraulic fluid from the chamber 53 via the bore 31, the pressure valve 30 into the pressure chamber 25th Dadurch wird der Kolben 4 mit Kolbenstange 6 und Druckplatte 8 aus dem Gehäuse 2 bewegt und fördert die Mischungskomponente mit dem größeren Mischungsanteil aus der Kartusche 1 in die Mischkammer 37 . Thereby, the piston 4 with the piston rod 6 and the pressure plate 8 is moved from the housing 2 and conveys the mixture component with the higher mixing proportion of the cartridge 1 into the mixing chamber 37th Nach dem Loslassen des Handhebels 10 wird dieser wieder durch die Feder 14 über den Kolben 12 in die Ausgangslage zurück gebracht. After releasing of the hand lever 10 this is brought back by the spring 14 through the piston 12 into the initial position. Dabei wird durch den Kolben 12 über das Saugventil 27 und die Bohrung 18 Hydraulik flüssigkeit aus dem Raum 26 in den Raum 53 geför dert. In this case, by the piston 12 via the suction valve 27 and the bore white- water in the space 53 18 hydraulic liquid from the space 26th Parallel dazu verläuft dieser Vorgang in gleicher Weise auch für die Seite mit der Kartusche 41 , nur mit dem Unterschied, daß der Kolbenhub des Kolbens 47 über den Hebel 43 und den Exzenter 45 dem verlangten Mischungs verhältnis angepaßt werden kann. Parallel to this process takes place in the same way, for the side with the cartridge 41, with the only difference that the piston stroke of the piston 47 via the lever 43 and the eccentric 45 the required mix ratio may be adjusted.

Gleichzeitig mit der Betätigung des Handhebels 10 wird über die Verbindungsstange 33 die Verschie bewelle 36 mit dem Flügelrad 40 in den Misch kammern 37 hin- und herbewegt. Simultaneously with the actuation of the hand lever 10, the displacement is bewelle 36 with the impeller 40 in the mixing chambers 37 back and forth through the connecting rod 33rd Durch die schräge Nut 38 in der Verschiebewelle 36 und dem in der Mischkammer 37 befestigten Stift 39 wird zusätzlich eine Drehbewegung des Flügelrades 40 erreicht. The inclined groove 38 in the sliding shaft 36 and mounted in the mixing chamber 37 pin 39 a rotational movement of the impeller 40 is achieved in addition. Durch diese kombinierte Dreh- und Schubbewegung wird eine besonders gute Mischung erreicht. This combined rotating and sliding movement a particularly good mix is ​​achieved. An Stelle von Nut 38 und Stift 39 kann auch ein Steilgewinde verwendet werden. In place of groove 38 and pin 39 and a ball thread may be used.

Diese Erfindung ist nicht nur auf die Anwendung von 2 Komponenten beschränkt; This invention is not limited only to the use of 2 components; man kann auch 3 oder mehr Komponenten zu einem Block zusammen fassen. you can take even three or more components into a block. Besonders vorteilhaft ist hier die Anwendung der hydraulischen Kraftübertragung. It is particularly advantageous here is the use of hydraulic power transmission. Je nach Verwendungszweck kann der Kolbenhub eines oder mehrerer Kolben stufenlos einstellbar sein. Depending on the intended use of the piston stroke of one or more pistons may be continuously adjustable.
