Description
Die Erfindung betrifft eine Vorrichtung zur Erzeugung einer Mehrkomponentenmischung, insbesondere Lack-Härter-Mischung, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for producing a multi-component mixture, in particular paint-hardener mixture, according to the preamble of claim 1.
Eine derartige Vorrichtung ist aus der
Nach der
Der damit verbundene Regelaufwand ist vergleichsweise hoch, weil die vorgenannten Absperrventile der Vorratsbehälter nur einen diskontinuierlichen Abfluss der jeweiligen Komponente aus dem Vorratsbehälter zulassen. Deshalb ist es Aufgabe der Erfindung, den Steuerungs- bzw. Regelungsaufwand gering zu halten und gleichwohl eine erhöhte Reproduzierbarkeit des Arbeitsergebnisses des jeweiligen Spritzgerätes zu erreichen.The associated control effort is relatively high because the aforementioned shut-off valves of the reservoir allow only a discontinuous outflow of the respective component from the reservoir. It is therefore an object of the invention to keep the control or regulation effort low and nevertheless to achieve an increased reproducibility of the work result of the respective sprayer.
Dies wird durch die kennzeichnenden Merkmale des neuen Anspruches 1 erreicht. Da bei der Erfindung die für die Komponenten vorgesehenen Druckquellen kontinuierlich mit den Druckleitungen kommunizieren, kann die zur Erzielung des gewünschten Mischungsverhältnisses vorgesehene Volumenstromsteuerung der Komponenten über einfach steuerbare Stromdrosseln erreicht werden.This is achieved by the characterizing features of the new claim 1. In the invention, since the pressure sources provided for the components communicate continuously with the pressure lines, the volumetric flow control of the components provided to achieve the desired mixing ratio can be achieved via easily controllable flow restrictors.
Aus der
Die Erfindung beruht auf dem allgemeinen Gedanken, den Volumenstrom der ersten Komponente als Führungsgröße für die Steuerung bzw. Regelung des Zustromes der weiteren Komponente bzw. Komponenten einzusetzen, wobei eine einfache und bedarfsgerechte Volumenstromsteuerung der Komponenten ausschließlich über steuerbare Stromdrosseln erreicht werden kann, wenn die Komponenten in den Druckleitungen unter einen hinreichenden Druck stehen bzw. den Druckleitungen unter entsprechendem Druck zugeführt werden.The invention is based on the general idea to use the volume flow of the first component as a reference variable for the control or regulation of the inflow of the other component or components, with a simple and needs-based flow control of the components can be achieved exclusively via controllable current throttles, if the components in the pressure lines are under a sufficient pressure or the pressure lines are supplied under appropriate pressure.
Dies kann beispielsweise dadurch erfolgen, daß für jede Komponente ein Druckreservoir vorgesehen bzw. das jeweilige Reservoir unter hinreichenden Druck gesetzt und gehalten wird.This can be done, for example, by providing a pressure reservoir for each component or by setting and holding the respective reservoir under sufficient pressure.
Grundsätzlich ist es jedoch auch möglich, Pumpen vorzusehen, um die jeweiligen Komponenten den zugeordneten Druckleitungen zuzuführen bzw. den Betriebsdruck in den Druckleitungen aufrechtzuerhalten. Letzteres kann beispielsweise dadurch erfolgen, daß die Pumpe im Umlauf gegen einen Drosselwiderstand fördert.In principle, however, it is also possible to provide pumps in order to supply the respective components to the associated pressure lines or to maintain the operating pressure in the pressure lines. The latter can be done, for example, that the pump promotes circulation against a throttle resistance.
Hierbei sind in der Regel Kolben- oder Membranpumpen bevorzugt.In this case piston or diaphragm pumps are preferred as a rule.
Im übrigen wird hinsichtlich bevorzugter Merkmale der Erfindung auf die Ansprüche sowie die nachfolgende Erläuterung der Zeichnung verwiesen, anhand der eine besonders bevorzugte Ausführungsform der Erfindung näher beschrieben wird.Moreover, with regard to preferred features of the invention to the claims and the following explanation of the drawing, reference is made to a particularly preferred embodiment of the invention will be described in more detail.
