Description
Die Erfindung betrifft eine Dosiereinrichtung für eine viskose Substanz, insbesondere zum Auftragen der Substanz. Mit der Dosiereinrichtung werden allgemein niedrig- bis hochviskose Substanzen wie Klebemittel, Fette, Öle aber auch z.B. pharmazeutische Substanzen etc. in exakt eingehaltenen Mengen abgegeben. Nachfolgend wird das zu dosierende Material allgemein als "viskose Substanz" bezeichnet.The The invention relates to a metering device for a viscous substance, in particular for applying the substance. With the metering device are general low to high viscosity substances such as adhesives, greases, oils but also e.g. pharmaceutical substances etc. in exactly kept Delivered quantities. Hereinafter, the material to be dosed becomes general referred to as "viscous substance".
Die
Der Erfindung liegt die Aufgabe zugrunde, eine insbesondere für die Kleinstmengenverarbeitung geeignete Dosiereinrichtung anzugeben, die eine kompakte Bauform hat.Of the Invention is based on the object, in particular for the smallest quantity processing specify suitable metering device, which has a compact design Has.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.These The object is achieved by the Characteristics of claim 1 solved.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.advantageous Embodiments of the invention are characterized in the subclaims.
Erfindungsgemäß wird vorgeschlagen, daß die Dosiereinrichtung einen Vorratsbehälter mit der viskosen Substanz enthält, der über eine Ventileinrichtung mit einem Verdrängerdosierer verbindbar ist, und daß die Ventileinrichtung ein Doppelsitzventil enthält, das entweder die Verbindung zwischen dem Vorratsbehälter und dem Verdrängerdosier oder die Verbindung zwischen dem Verdrängerdosierer und der Ventil-Auslaßöffnung freigibt.According to the invention, it is proposed that the Metering a reservoir with the viscous substance contains the over a valve means is connectable to a Verdrängerdosierer, and that the Valve device includes a double seat valve, which either the connection between the reservoir and the displacer dosing or releases the connection between the positive displacement doser and the valve outlet port.
Durch die erfindungsgemäße Anordnung des Doppelsitzventils werden separate Ein- und Auslaßventile vermieden, wodurch die Dosiereinrichtung eine kompakte Bauform erhält. Die Vermeidung der Ein- und Auslaßventile durch das Doppelsitzventil ist zudem dann besonders vorteilhaft, wenn feuchtigkeitsreaktive Substanzen aus der Dosiereinrichtung abgegeben werden sollen.By the inventive arrangement of Double seat valve, separate inlet and outlet valves are avoided, which the metering device receives a compact design. The avoidance of and exhaust valves The double-seat valve is also particularly advantageous if moisture-reactive substances are released from the metering device should be.
Die Materialzufuhr kann sowohl von großen als auch kleinen Vorratsgebinden erfolgen, wobei im letzteren Falle eine Vorratskartusche eingesetzt wird.The Material supply can be from both large and small storage containers take place, in the latter case, a supply cartridge used becomes.
Dabei ist weiter vorzugsweise vorgesehen, daß in die bevorzugt vorgesehene Kartusche ein Pneumatikkolben eingreift, der den zum überführen der viskosen Substanzen in den Verdrängerdosierer erforderlichen Druck erzeugt, und daß der Verdrängerdosierer eine pneumatische Kolben/Zylindereinheit enthält, deren Kolben Weg-gesteuert ist, wodurch eine exakt definierte Substanzmenge ausgestoßen wird. Die Ausgangsposition des Kolbens in dem Zylinder ist bevorzugt einstellbar.there is further preferably provided that in the preferred Cartridge engages a pneumatic piston, which converts the viscous substances required in the Verdrängerdosierer Pressure generated, and that the displacement- includes a pneumatic piston / cylinder unit whose piston is path-controlled is, whereby a precisely defined amount of substance is ejected. The starting position of the piston in the cylinder is preferably adjustable.
Bei der erfindungsgemäßen Dosiereinrichtung steht demnach dann, wenn ihr Doppelsitzventil die Ventil-Auslaßöffnung der Dosiereinrichtung verschließt, der Innenraum der Kartusche mit dem Zylinder des Verdrängerdosierers in Verbindung, um stets den Zylinderraum vor dem in die Ausgangsstellung zurückkehrenden Kolben wieder zu füllen. Wenn das Doppelsitzventil in die angehobene Stellung bewegt wird, in der die Ventil-Auslaßöffnung freigegeben ist, verschließt ein bevorzugt konischer Abschnitt der Ventilnadel einen entsprechend geformten Ventilsitz und unterbricht damit die Verbindung zwischen der Kartusche und dem Verdrängerdosierer, woraufhin der pneumatische Kolben des Verdrängerdosierers bis zu seiner exakt vorgegebenen Endlage vorgeschoben wird und die vorgesehene Materialmenge ausstößt.at the metering device according to the invention is therefore when their double seat valve, the valve outlet opening of the Closes metering device, the interior of the cartridge with the cylinder of the Verdrängerdosierers in connection to always the cylinder space before returning to the starting position To refill the piston. When the double-seat valve is moved to the raised position, in which the valve outlet opening released is, closes a preferred conical portion of the valve needle a corresponding shaped valve seat and thus breaks the connection between the cartridge and the displacement meter, whereupon the pneumatic piston of the positive displacement meter up to his exactly predetermined end position is advanced and the intended Material quantity ejects.
Die hin- und herbewegbare Ventilnadel hat dabei bevorzugt einen kugeligen Ventilnadelkopf, der mit einem entsprechend geformten Ventilsitz zusammenwirken kann, um die Ventilauslaßöffnung zu verschließen. In der rückwärtigen, oberen Lage läuft – wie oben erwähnt – ein konischer Abschnitt der Ventilnadel auf einen entsprechend geformten Ventilsitz auf.The reciprocable valve needle preferably has a spherical Valve needle head, with a correspondingly shaped valve seat can cooperate to close the valve outlet. In the back, upper layer runs - as above mentioned - a conical Section of the valve needle on a correspondingly shaped valve seat.
Die Position des in der Kartusche sitzenden pneumatischen Kolbens wird zweckmäßigerweise überwacht, wobei bei Erreichen eines minimalen Füllstandes eine Anzeige erfolgen sollte, daß eine neue, gefüllte Kartusche einzusetzen ist.The Position of the seated in the cartridge pneumatic piston is appropriately monitored, whereby a display is made when a minimum level is reached should that a new, filled Cartridge is to use.
Die erfindungsgemäße Dosiereinrichtung ist insbesondere zum exakten Ausbringen kleinster Mengen einer viskosen Flüssigkeit geeignet ist, beispielsweise in der Größenordnung von 0,01 cm3 oder auch weniger. Durch die Anordnung des Doppelsitzventils anstelle bisher üblicher Ein- und Auslaßventile läßt sich die Dosiereinrichtung nicht nur kleiner und kompakter gestalten, sondern es ist gewährleistet, daß die auszubringende Substanz in der Dosiereinrichtung mit keinerlei Feuchtigkeit in Berührung kommt, da die Verbindungsbahnen zwischen dem Vorratsbehälter und der Auslaßöffnung des Ventils stets vollständig mit auszubringender Substanz gefüllt sind, was insbesondere bei feuchtigkeitsreaktiven Materialien vorteilhaft ist.The metering device according to the invention is particularly suitable for the exact dispensing of minute amounts of a viscous liquid, for example of the order of 0.01 cm 3 or less. Due to the arrangement of the double seat valve instead of the usual inlet and outlet valves, the metering device can not only make smaller and more compact, but it is ensured that the auszubringende substance in the metering device with no moisture comes into contact, since the connecting paths between the reservoir and the Outlet opening of the valve are always completely filled with auszubringender substance, which is particularly advantageous in moisture-reactive materials.
