Abstract
Description
Die Erfindung betrifft ein Verfahren zum dosierten Mischen von pumpfähigen, insbesondere von pastösen und/oder flüssigen, Komponenten miteinander, welche mittels einer Komponentenpumpe in aufeinander abgestimmten Dosierungen einem Mischer zugeführt werden. Ferner betrifft die Erfindung eine Vorrichtung zum dosierten Mischen von pumpfähigen, insbesondere von pastösen und/oder flüssigen, Komponenten miteinander mit je einer Zuleitung, einer Komponentenpumpe und einem Durchflußmesser für jede Komponente sowie einem Mischer für die Komponenten.The invention relates to a method for the dosed mixing of pumpable, especially pasty ones and / or liquid, Components with each other, which are connected to each other by means of a component pump coordinated dosages are fed to a mixer. Furthermore concerns the invention a device for metered mixing of pumpable, in particular of pasty and / or liquid, Components with each other with a supply line, a component pump and a flow meter for every Component as well as a mixer for the components.
Ein solches Verfahren und eine solche
Vorrichtung sind in der
Diskontinuierliches Mischen ist immer dann ungeeignet, wenn das fertig gemischte Produkt für eine nachfolgende Weiterbearbeitung oder dergleichen in einem kontinuierlichen Massenstrom zur Verfügung gestellt werden muß. Diese Anforderung ist beispielsweise bei Kaschiermaschinen gegeben, in denen z. B. Folienbahnen fortlaufend miteinander verklebt werden. Die Folienbahnen laufen dabei über eine Auftragswalze für den Kleber und werden dabei mit dem Kleber beschichtet und sodann miteinander verklebt. Die Auftragswalze muß dabei kontinuierlich mit Kleber versorgt werden, da sonst Kaschierfehler auftreten könnten. Der Kleber selbst ist meist ein lösemittelhaltiger (LH) oder lösemittelfreier (LF) Zweikomponentenkleber aus einem Binder und einem Härter, der vor Ort, also unmittelbar vor dem Auftragen auf die Auftragswalze angemischt werden muß.Discontinuous mixing is always then unsuitable if the finished mixed product for a subsequent one Further processing or the like in a continuous mass flow to disposal must be asked. This requirement applies, for example, to laminating machines, in which e.g. B. foil webs are continuously glued together. The film webs run over a Applicator roller for the adhesive and are coated with the adhesive and then glued together. The application roller must continuously with Glue are supplied, since otherwise lamination errors could occur. The Glue itself is usually a solvent-based one (LH) or solvent-free (LF) Two-component adhesive consisting of a binder and a hardener that on site, i.e. immediately before application to the application roller must be mixed.
Hiervon ausgehend liegt der Erfindung das Problem zugrunde, ein Verfahren und eine Vorrichtung zum kontinuierlichen Mischen pumpfähiger Komponenten vorzuschlagen.The invention is based on this the problem underlying a method and apparatus for continuous Mixing pumpable components propose.
Zur Lösung dieses Problems ist das erfindungsgemäße Verfahren dadurch gekennzeichnet, daß die Komponenten dem Mischer kontinuierlich zugeführt werden und die erfindungsgemäße Vorrichtung dadurch gekennzeichnet, daß die Komponentenpumpe eine kontinuierlich arbeitende Förderpumpe, insbesondere eine Exzenterschneckenpumpe, vorzugsweise eine Moineaupumpe, ist.To solve this problem it is inventive method characterized in that the Components are continuously fed to the mixer and the device according to the invention characterized in that the Component pump a continuously operating feed pump, in particular an eccentric screw pump, preferably a Moineau pump, is.
Durch das kontinuierliche Pumpen der Komponenten in den Mischer werden die Komponenten im Mischer auch kontinuierlich vermischt und können einer nachfolgenden Verarbeitung kontinuierlich zugeführt werden. Als Komponentenpumpe eignet sich besonders gut eine Exzenterschneckenpumpe, vorzugsweise eine Moineaupumpe, da bei diesem Pumpentyp der Förderstrom nur von der Rotordrehzahl abhängig ist. Diese Pumpen lassen sich daher besonders einfach regeln.Through continuous pumping of the components in the mixer become the components in the mixer also mixed continuously and can be used for subsequent processing fed continuously become. An eccentric screw pump is particularly suitable as a component pump, preferably a Moineaupump, because with this type of pump the flow rate only dependent on the rotor speed is. These pumps are therefore particularly easy to control.
Um eine exakte Dosierung der Komponenten sicherzustellen, werden die Komponentenpumpen vorzugsweise in Abhängigkeit von Signalen einer Durchflußmessung, insbesondere einer Coriolis-Durchflußmessung, geregelt. Dabei sollten die Signale der einzelnen Durchflußmessungen jedes Komponentenstroms in einer zentralen Regeleinheit zusammengefaßt werden, um aufeinander abgestimmte Fließgeschwindigkeiten der einzelnen Komponenten und damit exakte Dosierungen zu erreichen. Es reicht im allgemeinen aber aus, wenn das Signal jeder Durchflußmessung nur für die Regelung der „eigenen" Komponentenpumpe verwendet wird, um einen genau vorherbestimmten Volumenstrom zu erhalten. Auch hierdurch wird bereits eine exakte Dosierung sichergestellt. Coriolis-Durchflußmesser eignen sich für den vorliegenden Anwendungsfall deshalb besonders, weil sie aufgrund ihres Meßprinzips die Durchflußmenge unabhängig von den Komponenteneigenschaften, wie z. B. Dichte und Viskosität, mit einer Meßgenauigkeit von ± 0,15 % bestimmen. Eine gesonderte Fehlerkorrektur für z. B. aufgrund von Temperaturschwankungen in der Mischanlage variierende Viskositäten und/oder Dichten ist nicht erforderlich.For an exact dosage of the components to ensure the component pumps are preferably dependent of signals from a flow measurement, especially a Coriolis flow measurement. Doing so the signals of the individual flow measurements of each component stream in a central control unit to be coordinated flow rates of the individual components and thus exact dosages. In general, however, it is sufficient if the signal of each flow measurement only for the regulation of the "own" component pump is used to obtain a precisely predetermined volume flow. This also ensures exact dosing. Coriolis flow meter are suitable for the present use case especially because it is due of their measuring principle flow independently from the component properties, such as B. density and viscosity, with a measurement accuracy of ± 0.15 % determine. A separate error correction for e.g. B. due to temperature fluctuations there are no varying viscosities and / or densities in the mixing plant required.
Nach einer Weiterbildung der Erfindung ist eine Rückspülleitung für die Komponenten vorgesehen. Hierdurch lassen sich die Komponenten im Kreislauf pumpen, ohne daß die Entnahme von fertig gemischtem Produkt aus dem Mischer gestoppt werden muß. Die Komponentenpumpen können also auch in einem solchen Fall ohne Unterbrechung weiter betrieben werden, so daß Anfahrverluste bzw. Anfahrdosierfehler vermieden werden.After a further development of the invention is a backwash line for the Components provided. This allows the components to be circulated pump without the Removal of finished mixed product from the mixer stopped must become. The component pumps can in such a case continue to operate without interruption so that start-up losses or start-up dosing errors can be avoided.
Die hier in Rede stehenden zu mischenden Stoffe (Komponenten) weisen oft bei Raumtemperatur eine Viskosität auf, die sie für die Entnahme aus Vorratsbehältern durch Absaugen ungeeignet macht. Der durch die Komponentenpumpe erzeugte Unterdruck reicht hierzu nicht aus. Bisher werden daher meist sogenannten Faßstempel vorgesehen, die von oben auf die Komponenten drücken und damit die Komponenten in eine Entnahmelanze, beispielsweise eine Faßlanze, zur Entnahme der Komponenten aus dem Behälter drücken. Es sind also zwei Fördereinrichtungen, nämlich der Faßstempel und die Komponentenpumpe erforderlich. Zur Vermeidung dieses Nachteils ist nach einer, auch unabhängig denkbaren, Weiterbildung der Erfindung vorgesehen, daß insbesondere die Entnahmelanze, aber auch weitere Förderleitungen für die Komponenten und ggf. auch das fertig gemischte Produkt zum Herabsetzen der Viskosität beheizt sind. Die Heizung ist vorzugsweise spiralförmig um die Leitung gewunden. Eine elektrische Widerstandsheizung bietet sich für die vorliegende Anwendung an.The substances (components) to be mixed in question here often have a viscosity at room temperature which makes them unsuitable for removal from storage containers by suction. The negative pressure generated by the component pump is not sufficient for this. So far, so-called barrel stamps have therefore mostly been provided, which press on the components from above and thus press the components into a removal lance, for example a barrel lance, for removing the components from the container. So two conveyors, namely the barrel ram and the component pump are required. In order to avoid this disadvantage, one can also think independently Ren, development of the invention provided that in particular the removal lance, but also other delivery lines for the components and possibly also the finished mixed product to reduce the viscosity are heated. The heater is preferably wound in a spiral around the line. An electrical resistance heater is suitable for the present application.
Schließlich betrifft die Erfindung eine Entnahmelanze, insbesondere für derartige Vorrichtungen, zur Entnahme von Stoffen aus Vorratsbehältern. Bei herkömmlichen Entnahmelanzen besteht ebenfalls das vorstehend erläuterte Problem, daß Stoffe mit höherer Viskosität nicht durch Ansaugen aus einem Vorratsbehälter entnommen werden können. Zur Vermeidung dieses Nachteils ist die erfindungsgemäße Entnahmelanze beheizt. Die Heizung der Entnahmelanze ist dabei vorzugsweise in einem zwischen einem Innenrohr und einem Außenrohr gebildeten Ringraum angeordnet, so daß sie gegen Verschmutzung geschützt ist. Der Ringraum sollte zu diesem Zweck an beiden Enden verschlossen sein. Als Heizung bietet sich wieder eine elektrische Widerstandsheizung an, die vorzugsweise spiralförmig um das Innenrohr gewunden ist.Finally, the invention relates a removal lance, in particular for such devices, for Removal of substances from storage containers. With conventional Extraction lances also have the problem explained above, that fabrics with higher viscosity cannot be removed from a storage container by suction. To avoid this disadvantage is the removal lance according to the invention heated. The Heating of the removal lance is preferably in between one Inner tube and an outer tube formed annulus arranged so that it is protected against contamination. For this purpose, the annulus should be closed at both ends his. An electrical resistance heater is again available as a heater at, preferably spiral is wound around the inner tube.
