Abstract

A device for dispensing metered quantities of flowable multi-component masses includes a housing with separate chambers, each containing a flexible bag with one component of the multi-component mass. Material is pressed out of the bags by a liquid propellant supplied from a reservoir in the housing to the chambers by gear wheel pumps located in a conduit connecting the reservoir to the chambers. The pumps are connected to a common drive so that the mixture ratio of the components is exactly maintained for any desired amount to be dispensed.

Description

Die Erfindung betrifft eine Vorrichtung zum Auspressen und dosierten Abgeben von fliessfähigen Mehrkomponenten-Massen unter Einwirken eines Treibmittels auf flexible Beutel für die einzelnen Komponenten der Masse, wobei jeder Beutel in einem gesonderten Behälter angeordnet ist.The invention relates to a device for squeezing and metered dispensing of flowable multicomponent masses under the action of a blowing agent on flexible bags for the individual components of the mass, each bag being arranged in a separate container.

Mehrkomponenten-Massen werden in zunehmendem Ausmass für viele Anwendungen in Industrie und Gewerbe zum Kleben, Füllen, Abdichten und dergleichen verwendet. Um eine vorzeitige Reaktion der Komponenten miteinander zu verhindern, müssen die einzelnen Komponenten in voneinander getrennten Kammern gelagert werden.Multi-component compositions are increasingly being used for many industrial and commercial applications for gluing, filling, sealing and the like. To prevent the components from reacting prematurely, the individual components must be stored in separate chambers.

Bei einem bekannten System ist jede Komponente in einer separaten, zylinderförmigen Kartusche mit darin verschiebbarem Auspresskolben angeordnet, was sehr aufwendig ist und zu hohen Herstellungskosten führt. Ausserdem können bei den zum Teil sehr hohen Auspressdrücken Abdichtprobleme am Auspresskolben auftreten. Ist der Auspresskolben nicht absolut dicht, so entstehen Verschmutzungen des für die Verarbeitung der Kartuschen erforderlichen Auspressgerätes.In a known system, each component is arranged in a separate, cylindrical cartridge with an ejection piston which can be displaced therein, which is very complex and leads to high production costs. In addition, sealing problems can occur on the squeezing piston at the sometimes very high squeezing pressures. If the ejection piston is not absolutely leak-proof, the ejection device required for processing the cartridges is contaminated.

Aus Kosten- sowie auch aus Abdichtungsgründen ist es weiterhin bekannt, die Komponenten in flexiblen Beuteln anzuordnen. Diese Beutel werden mechanisch, beispielsweise mittels Walzen oder mittels eines auf die Wandung der Beutel einwirkenden Treibmittels ausgequetscht. Bei einer aus der DE-A 2 644 780 bekannten Vorrichtung sind die Beutel in einem gemeinsamen Behälter angeordnet und werden somit vom gleichen Druck des Treibmittels beaufschlagt. Die Abgabe der Komponenten kann somit nur bei etwa gleicher Viskosität der Komponenten in einem bestimmten, gleichbleibenden Mischungsverhältnis erfolgen. Bei den insbesondere im Baugewerbe eingesetzten Mehrkomponenten-Massen ist jedoch die Viskosität der einzelnen Komponenten sehr unterschiedlich und zudem in Abhängigkeit von der Umgebungstemperatur veränderlich. Die Einhaltung eines bestimmten Mischungsverhältnisses ist bei diesen Massen mit der genannten Vorrichtung somit nicht gewährleistet. Aus der GB-A 2 063 371 ist eine Vorrichtung zum Auspressen von in flexiblen Beuteln angeordneten Komponenten einer Mehrkomponenten-Masse bekannt. Dabei sind die Beutel in zwei gesonderten Behältern angeordnet und werden vom gleichen Treibmittel und somit auch vom gleichen Druck beaufschlagt.For cost and sealing reasons, it is also known to arrange the components in flexible bags. These bags are mechanically squeezed, for example by means of rollers or by means of a blowing agent acting on the wall of the bags. In a device known from DE-A 2 644 780, the bags are arranged in a common container and are therefore acted upon by the same pressure of the propellant. The components can thus only be dispensed when the components have approximately the same viscosity in a certain, constant mixing ratio. In the multi-component compositions used in particular in the construction industry, however, the viscosity of the individual components is very different and, moreover, varies depending on the ambient temperature. With these masses, compliance with a certain mixing ratio cannot be guaranteed with these devices. From GB-A 2 063 371 a device for pressing out components of a multi-component mass arranged in flexible bags is known. The bags are arranged in two separate containers and are acted upon by the same propellant and thus by the same pressure.

Dies führt dazu, dass eine exakte Dosierung der Komponenten insbesondere bei unterschiedlicher Viskosität nicht möglich ist.This means that an exact dosing of the components is not possible, especially with different viscosities.

Aus der GB-A 1 467 637 ist eine ausschliesslich zum Auspressen von Einkomponenten-Massen geeignete Vorrichtung bekannt. Bei dieser Vorrichtung wird ein flüssiges Treibmittel mittels einer Zahnradpumpe von einem Vorratstank zur rückwärtigen Stirnseite eines in einer Kartusche axial verschiebbaren Auspresskolbens geleitet.GB-A 1 467 637 discloses a device which is only suitable for pressing out one-component compositions. In this device, a liquid propellant is conducted by means of a gear pump from a storage tank to the rear end of an ejection piston which is axially displaceable in a cartridge.

Der Erfindung liegt die Aufgabe zugrunde, eine einfache, kompakte Vorrichtung zum Auspressen von in flexiblen Beuteln angeordneten Komponenten einer Mehrkomponenten-Masse in einem vorbestimmten Mischungsverhältnis zu schaffen.The invention has for its object to provide a simple, compact device for pressing components of a multi-component mass arranged in flexible bags in a predetermined mixing ratio.

Ausgehend von den GB-A 2 063 371 wird die gestellte Aufgabe dadurch gelöst, daß den Behältern das Treibmittel jeweils über eine separate, als volumetrisch fördernde Zahnradpumpe ausgebildete Dosiereinrichtung zugeführt wird, und die Zahnradpumpen für die einzelnen Komponenten über eine gemeinsame Antriebswelle miteinander gekoppelt sind.Starting from GB-A 2 063 371, the stated object is achieved in that the propellant is supplied to the containers in each case via a separate metering device designed as a volumetric conveying gear pump, and the gear pumps for the individual components are coupled to one another via a common drive shaft.

Die Zahnradpumpen können von Hand oder über einen Motor angetrieben werden, benötigen keine Ventile und sind in beiden Förderrichtungen gleich gut betreibbar.The gear pumps can be driven by hand or by a motor, do not require valves and can be operated equally well in both delivery directions.

Dadurch dass die Pumpen für die einzelnen Komponenten miteinander gekoppelt sind, kann das Mischungsverhältnis der Komponenten konstant gehalten werden. Diese Koppelung der Pumpen kann durch direkte Verbindung der Pumpen über eine gemeinsame Antriebswelle erfolgen. Durch ein zwischengeschaltetes Schalt- oder Wechselgetriebe kann das Mischungsverhältnis auch verändert werden. Eine weitere Möglichkeit besteht darin, die Antriebsmotoren für die einzelnen Pumpen elektronisch zu regeln.Because the pumps for the individual components are coupled to one another, the mixing ratio of the components can be kept constant. This coupling of the pumps can be done by directly connecting the pumps via a common drive shaft. The mixing ratio can also be changed by an intermediate manual or change gearbox. Another option is to electronically control the drive motors for the individual pumps.

Beim Einlegen der Beutel in die Behälter verbleibt in der Regel ein gewisses Restvolumen, das zu Beginn des Auspressvorganges mit Luft gefüllt ist. Ein solches Luftpolster kann die Dosierung der Komponenten störend beeinflussen, so dass das vorgegebene Mischungsverhältnis nicht mehr eingehalten werden kann. Um dies zu vermeiden, ist es vorteilhaft, dass die Behälter Entlüftungsventile aufweisen. Diese Entlüftungsventile werden zu Beginn des Auspressvorganges so lange betätigt, bis das Treibmittel aus den Entlüftungsventilen austritt. Anstelle von manuell betätigbaren Entlüftungsventilen können auch sogenannte Automatik-Ventile verwendet werden, welche selbsttätig sperren, sobald Flüssigkeit in das Ventil eintritt.When the bags are placed in the containers, there is usually a certain residual volume that is filled with air at the start of the squeezing process. Such an air cushion can interfere with the dosage of the components, so that the specified mixing ratio can no longer be maintained. In order to avoid this, it is advantageous for the containers to have ventilation valves. These vent valves are operated at the beginning of the squeezing process until the propellant emerges from the vent valves. Instead of manually operated vent valves, so-called automatic valves can also be used, which block automatically as soon as liquid enters the valve.

Die Erfindung soll anhand der sie beispielsweise wiedergebenden Zeichnungen näher erläutert werden. Es zeigen:

  • Fig. 1 eine erfindungsgemässe Vorrichtung zum Auspressen und dosierten Abgeben von Mehrkomponenten-Massen, im Schnitt dargestellt,
  • Fig. 2 einen Schnitt durch das in Fig. 1 dargestellte Gerät entlang der Linie 11-11.
The invention will be explained in more detail with reference to the drawings, for example. Show it:
  • 1 shows a device according to the invention for pressing and dispensing multicomponent masses, shown in section,
  • Fig. 2 shows a section through the device shown in Fig. 1 along the line 11-11.

Die aus Fig. 1 ersichtliche, erfindungsgemässe Vorrichtung besteht im wesentlichen aus einem insgesamt mit 1 bezeichneten Gehäuse und einem damit verbundenen, insgesamt mit 2 bezeichneten Deckelteil. Das Gehäuse 1 weist einen seitlich wegragenden Handgriff 1a auf. Zwischen dem Gehäuse 1 und dem Deckelteil 2 ist eine Dichtung 3 angeordnet. Das Deckelteil 2 ist mit einem Gewindeansatz 2a für einen insgesamt mit 4 bezeichneten Auspressstutzen versehen. Im Auspressstutzen 4 sind Mischelemente 4a angeordnet. Das Deckelteil 2 weist in den Gewindeansatz 2a mündende Kanäle 2b, 2c auf. In das eine Ende der Kanäle 2b, 2c sind Anschlussnippel 5 eingesetzt. Das Gehäuse 1 weist zwei parallel zueinander angeordnete Behälter 1b, 1 c für Beutel 6, 7 auf, welche die Komponenten 8, 9 einer Mehrkomponenten-Masse enthalten. Die Beutel 6, 7 sind über die Anschlussnippel 5 mit dem Deckelteil 2 verbunden. Das Gehäuse 1 und das Deckelteil 2 weisen je eine Entlüftungsbohrung 1d, 2d auf. Die Entlüftungsbohrungen 1d, 2d stehen in Verbindung mit einem manuell betätigbaren, insgesamt mit 10 bezeichneten Entlüftungsventil. Das Entlüftungsventil 10 besteht aus einem Ventilkörper 10a, einem Stössel 10b und einer den Stössel 10b gegen den Ventilkörper 10a treibenden Druckfeder 1 Oc.The device according to the invention shown in FIG. 1 essentially consists of a housing, generally designated 1, and a cover part connected thereto, generally designated 2. The housing 1 has a handle 1a projecting to the side. A seal 3 is arranged between the housing 1 and the cover part 2. The cover part 2 is provided with a threaded attachment 2a for a press-out connection designated 4 overall. Mixing elements 4a are arranged in the squeeze nozzle 4. The cover part 2 has channels 2b, 2c opening into the threaded attachment 2a. Connection nipples 5 are inserted into one end of the channels 2b, 2c. The housing 1 has two containers 1b arranged parallel to one another, 1 c for bags 6, 7, which contain the components 8, 9 of a multi-component mass. The bags 6, 7 are connected to the cover part 2 via the connection nipple 5. The housing 1 and the cover part 2 each have a vent hole 1d, 2d. The vent holes 1d, 2d are connected to a manually operable vent valve, generally designated 10. The vent valve 10 consists of a valve body 10a, a tappet 10b and a compression spring 1 oc driving the tappet 10b against the valve body 10a.

Im Handgriff 1a ist ein Tank 11 angeordnet, der ein flüssiges Treibmittel 12, beispielsweise ein Hydraulikoel enthält. Das Treibmittel 12 gelangt über einen Ansaugstutzen 13 und eine Ansaugleitung 1 e im Gehäuse 1 zu zwei nebeneinander angeordneten Zahnradpumpen 14, 15. Die Zahnradpumpen 14, 15 werden durch eine gemeinsame Antriebswelle 16 angetrieben und sind somit miteinander gekoppelt. Die Antriebswelle 16 ist mit einem Tellerrad 17 verbunden. Das Tellerrad 17 steht im Eingriff mit einem Kegelritzel 18, das mit der Welle eines Motors 19 verbunden ist. Der Motor 19 wird von einer in einer Aufnahmeöffnung 1 des Gehäuses 1 angeordneten Batterie 20 angetrieben. Die Batterie 20 wird durch einen Verschlusspfropfen 21 und eine Kontaktfeder 22 in axialer Richtung gesichert. Die elektrische Verbindung des Motors 19 mit der Batterie 20 erfolgt über einen am Handgriff 1a angeordneten Schalter 23. Mit dem Schalter 23 können der Motor 19 und somit die Zahnradpumpen 14 und 15 ein- und ausgeschaltet und somit Treibmittel 12 vom Tank 11 über Druckleitungen 1f, 1g in die Behälter 1b, 1c geleitet werden. Durch das in die Behälter 1b, 1 c geleitete Treibmittel 12 werden die in den Beuteln 6, 7 enthaltenen Komponenten 8, 9 aus diesen herausgepresst und über die Kanäle 2b, 2c in den Auspressstutzen 4 geleitet. Mit den den Entlüftungsventilen 10 kann zu Beginn des Auspressvorganges in den Behältern 1 b, 1 c vorhandene Luft aus diesen entfernt werden. Solche Luftpolster könnten sonst die kontinuierliche Abgabe der Komponenten 8, 9 behindern. Wenn die Beutel 6, 7 vollständig entleert sind, kann die Drehrichtung des Motors 19 mittels des Schalters 23 umgekehrt und das Treibmittel 12 wieder in den Tank 11 zurückgefördert werden. Nachdem die Behälter 1b, 1c vollständig entleert sind, wird das Deckelteil 2 entfernt und die leeren Beutel 6, 7 werden gegen neue, gefüllte Beutel 6, 7 ausgetauscht.A tank 11 is arranged in the handle 1a and contains a liquid propellant 12, for example a hydraulic oil. The propellant 12 passes through an intake port 13 and an intake line 1 e in the housing 1 to two gear pumps 14, 15 arranged next to one another. The gear pumps 14, 15 are driven by a common drive shaft 16 and are thus coupled to one another. The drive shaft 16 is connected to a ring gear 17. The ring gear 17 is in engagement with a bevel pinion 18 which is connected to the shaft of a motor 19. The motor 19 is driven by a battery 20 arranged in a receiving opening 1 of the housing 1. The battery 20 is secured in the axial direction by a plug 21 and a contact spring 22. The electrical connection of the motor 19 to the battery 20 takes place via a switch 23 arranged on the handle 1a. With the switch 23, the motor 19 and thus the gear pumps 14 and 15 can be switched on and off and thus propellant 12 from the tank 11 via pressure lines 1f, 1g are passed into the containers 1b, 1c. The components 8, 9 contained in the bags 6, 7 are pressed out of the latter by the propellant 12 which is passed into the containers 1b, 1c and passed through the channels 2b, 2c into the squeeze nozzle 4. With the venting valves 10, air present in the containers 1b, 1c can be removed from the latter at the beginning of the pressing-out process. Such air cushions could otherwise hinder the continuous delivery of components 8, 9. When the bags 6, 7 are completely emptied, the direction of rotation of the motor 19 can be reversed by means of the switch 23 and the propellant 12 can be conveyed back into the tank 11. After the containers 1b, 1c are completely emptied, the lid part 2 is removed and the empty bags 6, 7 are exchanged for new, filled bags 6, 7.

Der in Fig. 2 dargestellte Querschnitt zeigt die Zahnradpumpe 14 mit der Antriebswelle 16 sowie der im Gehäuse 1 angeordneten Ansaugleitung 1 und Druckleitung 1f.The cross section shown in FIG. 2 shows the gear pump 14 with the drive shaft 16 and the suction line 1 and pressure line 1f arranged in the housing 1.
