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; dies gilt beispielsweise für bestimmte Klebstoffe.Dispensing guns for two components used when the two components may come together during processing, since they harden in a very short time; this applies to certain adhesives, for example.

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. Da das Mischungsverhältnis der beiden Komponenten normalerweise nicht 1 : 1 beträgt, wird die Kartusche mit dem kleineren Volumen mit einem entsprechend kleineren Durchmesser versehen. Die Mischkammer besteht aus einem meist konischen Rohr mit festangebrachten Prallkörpern, durch welches die beiden Komponenten gefördert werden. Um eine gute Mischung zu erzielen, müssen die Prallkörper oder Prallflächen sehr eng gestellt werden, so daß zum Durchströmen hohe Drücke erforderlich sind.Known dispensing guns use two cartridges lying in parallel, separated by two mechanically driven synchronously running Piston into a common static mix chamber with discharge nozzle can be emptied. Because the mixing ratio of the two components is usually not 1: 1, the Cartridge with the smaller volume a correspondingly smaller diameter Mistake. The mixing chamber consists of one mostly conical tube with fixed Impact bodies through which the two Components are promoted. To be a good one To achieve a mixture, the impact bodies must or baffles are placed very closely, so that high pressures are required for flow are.

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. 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.The device according to the present invention uses two equal, parallel to each other lying cartridges, which by two with running at different speeds, hydraulically operated pistons in a common Mixing chamber to be emptied. To make a good mix to achieve the two components is in the impeller through the mixing chamber Actuation of the hand lever via a connector extension rod in a reciprocating  and spinning motion.

Fig. 1 zeigt einen Längsschnitt durch die Dosierpistole mit der gestrichelt gezeichneten Kartusche 1 für die Komponente mit dem größeren Mischungsanteil. Im Gehäuse 2 befindet sich das Zylinderrohr 3 mit dem Kolben 4 und der Dichtung 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. Das untere Ende des Gehäuses ist als Pistolengriff 9 ausge­ führt. Der Handhebel 10 ist um die im Gehäuse 2 gelagerte Achse 11 schwenkbar. 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. Der Hub des Stufenkolbens 12 wird durch den Anschlag 15 am Gehäuse begrenzt. 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. Fig. 1 shows a longitudinal section through the dosing gun with the dashed cartridge 1 for the component with the larger proportion of the mixture. The cylinder tube 3 with the piston 4 and the seal 5 is located in the housing 2 . The piston rod 6 is fixedly connected to the piston 4 and leads through the seal 7 out of the housing 2 and is provided at the other end with the pressure plate 8 , which is inserted into the open end of the cartridge 1 . The lower end of the housing is out as a pistol grip 9 . The hand lever 10 is pivotable about the axis 11 mounted in the housing 2 . The Stufenkol ben 12 is slidably arranged in the housing 2 and exits through the seal 13 from the housing 2 and is pressed by the spring 14 in the direction of the hand lever 10 . The stroke of the stepped piston 12 is limited by the stop 15 on the housing. The control piston 16 can only be pressed against the action of the spring 17 into the housing 2 by pushing out the hand lever 10 and then connects the two control bores 18 and 19 to one another.

Das Innere des Gehäuses 2 ist restlos mit Hydraulikflüssigkeit gefüllt. 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. 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. Die Membran 20 mit Platte 21 und Feder 22 wird durch einen Gehäusedeckel 23 vor Beschädigungen von außen geschützt.The interior of the housing 2 is completely filled with hydraulic fluid. In order to catch volume changes due to the piston rods emerging from the housing 2 and due to thermal expansion, the housing 2 is closed at the upper end by an elastic membrane 20 . This membrane is pressed over the plate 21 by the spring 22 into the housing and keeps the hydraulic fluid constantly dig under a slight excess pressure. The membrane 20 with plate 21 and spring 22 is protected from damage from the outside by a housing cover 23 .

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 unpressurized side 26 of this piston.

Das Saugventil 27 besteht aus einem gerollten dünnen, elastischen, offenen Stahlblechring mit geringer Vorspannung, ähnlich einem Kolbenring an der Wand anliegend. Das eine Ende 28 ist im Gehäuse befestigt, das lose Ende 29 liegt vor der Steuerbohrung 18 (Fig. 3).The suction valve 27 consists of a rolled, thin, elastic, open sheet steel ring with low preload, similar to a piston ring against the wall. One end 28 is fixed in the housing, the loose end 29 is in front of the control bore 18 ( Fig. 3).

Das Druckventil 30 ist gleich ausgebildet, das lose Ende liegt hier vor der Bohrung 31.The pressure valve 30 is of identical design, the loose end here lies in front of the bore 31 .

Am Gelenkpunkt 32 des Handhebels 10 ist die Verbindungsstange 33 befestigt.The connecting rod 33 is attached to the articulation point 32 of the hand lever 10 .

Das andere Ende 34 dieser Verbindungsstange ist gabelförmig ausgebildet und greift in den Hals 35 der Verschiebewelle 36 der Misch­ kammer 37 ein. 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.The other end 34 of this connecting rod is fork-shaped and engages in the neck 35 of the shift shaft 36 of the mixing chamber 37 . In the sliding shaft 36 , an oblique groove 38 is incorporated, which is in the mixing chamber 37 th pin 39 engaged.

Mit der Verschiebewelle 36 fest verbunden ist ein Flügelrad 40.An impeller 40 is fixedly connected to the displacement shaft 36 .

Fig. 2 zeigt einen Teil-Längsschnitt durch die Dosierpistole mit der gestrichelt gezeich­ neten Kartusche 41 für die Komponente mit dem geringeren Mischungsanteil. Hier wirkt der Handhebel 10 nicht mehr direkt auf den Kolben 42, sondern unter Zwischenschaltung eines Hebels 43. 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. Der Exzenter 45 ist mit seiner Welle 49 drehbar im Gehäuse 2 gelagert und kann in jeder Lage fixiert werden. Fig. 2 shows a partial longitudinal section through the dispensing gun with the dashed line marked cartridge 41 for the component with the lower proportion of the mixture. Here the hand lever 10 no longer acts directly on the piston 42 , but with the interposition of a lever 43 . This lever sits with its bore on the pin 44 of the eccentric 45 and is pressed by the spring 46 via the piston 47 with its nose 48 against the hand lever 10 . The eccentric 45 is rotatably mounted with its shaft 49 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. Durch Drehung des Exzenters 45 um 180° wird der Hub des Kolbens 47 am größten.In the position shown, the nose 48 is at the smallest distance from the axis 11 of the hand lever 10 , the piston 47 makes the smallest stroke. By turning the eccentric 45 by 180 °, the stroke of the piston 47 is greatest.

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. Die Abdeckhaube 50 kann über den Drehpunkt 51 nach oben geschwenkt werden, um die Kartuschen zu wechseln. Fig. 4 shows a side view of the dosing gun. The cover 50 can be pivoted upwards about the pivot point 51 in order to change the cartridges.

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

WirkungsweiseMode of action

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. 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. Jetzt kann die Druckplatte 8 mit Kolbenstange 6 und Kolben 4 in das Gehäuse 2 verschoben werden. Das gleiche gilt auch für die Druckplatte auf der Seite der Kartusche 41 für den geringeren Mischungsanteil.After opening, the two cartridges 1 and 41 are screwed into the mixing chamber 37 by cutting the thread tip and inserted into the sier gun together and fixed by folding down the cover 50 . Should the pressure plate 8 be extended too far, the control piston 18 can be pressed into the housing 2 by lifting (pushing out) the hand lever 10 , whereby the pressure side 25 is connected to the pressure-free side 26 via the control bores 17 and 18 . Now the pressure plate 8 with piston rod 6 and piston 4 can be moved into the housing 2 . The same also applies to the pressure plate on the side of the cartridge 41 for the lower proportion of the mixture.

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. 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. Nach dem Loslassen des Handhebels 10 wird dieser wieder durch die Feder 14 über den Kolben 12 in die Ausgangslage zurück­ gebracht. 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. 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.By actuating the hand lever 10 , the piston 12 is pressed into the housing 2 and urges the hydraulic fluid out of the space 53 through the bore 31 , the pressure valve 30 into the pressure space 25 . As a result, the piston 4 with the piston rod 6 and the pressure plate 8 is moved out of the housing 2 and conveys the mixture component with the larger mixture fraction from the cartridge 1 into the mixing chamber 37 . After releasing the hand lever 10 , it is brought back into the starting position by the spring 14 via the piston 12 . In this case, hydraulic fluid is conveyed from the chamber 26 into the chamber 53 by the piston 12 via the suction valve 27 and the bore 18 . In parallel, this process runs in the same way for the side with the cartridge 41 , only with the difference that the piston stroke of the piston 47 can be adapted to the required mixture ratio via the lever 43 and the eccentric 45 .

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. 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. Durch diese kombinierte Dreh- und Schubbewegung wird eine besonders gute Mischung erreicht. An Stelle von Nut 38 und Stift 39 kann auch ein Steilgewinde verwendet werden.Simultaneously with the actuation of the hand lever 10 , the shifting shaft 36 is moved back and forth with the impeller 40 in the mixing chambers 37 via the connecting rod 33 . Through the oblique groove 38 in the sliding shaft 36 and the pin 39 fastened in the mixing chamber 37 , a rotary movement of the impeller 40 is additionally achieved. A particularly good mixture is achieved through this combined rotating and pushing movement. Instead of groove 38 and pin 39 , a steep thread can also be used.

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