Abstract

The appliance (1) transfers a set volume of a viscous fluid from a storage vessel into a container. The storage vessel (2) has a discharge valve (3) closed by a moveable valve rod (4). The valve is sealed relative to the storage vessel via a moveable sleeve (5) inside the vessel. The sleeve contains a relatively moving piston (6), which sucks the fluid from the vessel into the sleeve, and discharges it from the sleeve through the valve. Valve rod, sleeve, and piston are moveable independently of each other/ .

Description

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff von Hauptanspruch 1.The invention relates to a device according to the preamble of main claim 1.
Das Problem bei den bekannten Vorrichtungen besteht darin, daß die in der Flüssigkeit enthaltenen festen Stoffe das Dosieren, insbesondere das Schließen der Ventile am Ende des Dosiervorganges behindern können. In nachteiliger Weise kann es zu Fehldosierungen kommen.The problem with the known devices is that dosing the solid substances contained in the liquid, especially the closing of the valves at the end of the Can hinder dosing. Adversely, it can incorrect dosages occur.
Die Aufgabe der vorliegenden Erfindung ist es nun eine Vorrichtung zu schaffen, durch welche ein exaktes Dosieren auch dann möglich ist, wenn ein fester Stoff das Schließen des Ventils am Ende des Dosiervorgangs behindern würde.The object of the present invention is now a To create device by which an exact dosing also is then possible when a solid material closes the Valve would hinder at the end of the metering process.
Die Lösung dieser Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Hauptanspruchs.The solution to this problem follows from the characteristic ones Features of the main claim.
Die Unteransprüche betreffen Weiterbildungen und/oder besondere Ausgestaltungen der Erfindung.The sub-claims relate to further training and / or special Embodiments of the invention.
Die Überlegungen, die zur Entstehung der vorliegenden Erfindung führten gingen davon aus, daß die Dosierung der abzufüllenden Flüssigkeit unabhängig vom Öffnen und Schließen des Füllventils geschehen muß und das Ventil so gestaltet sein muß, daß ein im Ventil befindlicher fester Stoff beim Schließen des Ventils aus dem Ventilbereich entfernt wird.The considerations leading to the making of the present invention assumed that the dosage of the to be filled Liquid regardless of the opening and closing of the filling valve must happen and the valve must be designed so that an im Solid substance present in the valve when the valve is closed the valve area is removed.
Nachfolgend ist die Funktionsweise der erfindungsgemäßen Vorrichtung anhand mehrerer schematisierter Stellungen der Vorrichtung während des Abfüllvorgangs näher erläutert.Below is the operation of the invention Device based on several schematic positions of the Device explained in more detail during the filling process.
Die Fig. 1 zeigt mehrere Dosiereinheiten 1 nebeneinander angeordnet. Jede der einzelnen Dosiereinheiten befindet sich in einer anderen Phase des Dosiervorgangs. Jede Dosiereinheit besteht aus einem Vorratsbehälter 2, einer Austrittsdüse 3, einem beweglichen Stößel 4, durch den die Austrittsdüse 3 verschließbar ist, einer innerhalb des Vorratsbehälters 2 beweglichen Steckhülse 5 und einem in der Steckhülse 5 beweglichen Ringkolben 6. Im Ringkolben 6 verläuft wiederum der Stößel 4. Der Ringkolben weist sowohl hinsichtlich der Steckhülse 5, als auch des Stößels 4 Dichtungen auf. Ebenso ist die Erfindung auch in dichtungsloser Ausführung möglich, sofern die miteinander zusammenwirkenden Teile eine entsprechende Präzision aufweisen, eine Keramikausführung ist hier denkbar. Die Austrittsdüse 3, der Stößel 4, die Steckhülse 5 und der Ringkolben 6 haben eine gemeinsame Achse 7. Der Vorratsbehälter 2 ist mit einer Flüssigkeit F gefüllt. Fig. 1 shows a plurality of dosing units 1 arranged side by side. Each of the individual dosing units is in a different phase of the dosing process. Each dosage unit consists of a storage container 2, an outlet nozzle 3, a movable plunger 4, can be closed by the outlet nozzle 3, a movable within the reservoir 2 plug-in sleeve 5 and a movable sleeve 5 in the plug annular piston. 6 The plunger 4 again runs in the annular piston 6 . The annular piston has 4 seals both with regard to the plug-in sleeve 5 and the plunger. Likewise, the invention is also possible in a sealless version, provided that the interacting parts have a corresponding precision, a ceramic version is conceivable here. The outlet nozzle 3 , the plunger 4 , the plug-in sleeve 5 and the annular piston 6 have a common axis 7 . The reservoir 2 is filled with a liquid F.
Die Austrittsdüse 3, der Stößel 4, die Steckhülse 5 und der Ringkolben 6 werden durch Aktoren bewegt, die aus Gründen der Übersichtlichkeit nicht gezeichnet sind. Die Aktoren können sowohl auf dem elektrischen, hydraulischen oder pneumatischen Prinzip beruhen. Auch eine Mechanik mit Zentralantrieb ist denkbar.The outlet nozzle 3 , the plunger 4 , the plug-in sleeve 5 and the annular piston 6 are moved by actuators, which are not shown for reasons of clarity. The actuators can be based on the electrical, hydraulic or pneumatic principle. A mechanism with a central drive is also conceivable.
Unterhalb der Austrittsdüse 3 befindet sich der zu befüllende Behälter B.The container B to be filled is located below the outlet nozzle 3 .
Die Phase a zeigt die Vorrichtung 1 nach Beendigung des Abfüllvorganges.Phase a shows the device 1 after the filling process has ended.
Der Stößel 4 verschließt die Austrittsdüse 3. Die Steckhülse 5 und der Ringkolben 6 haben ihre Endstellung erreicht. In dieser Endstellung sitzt die der Austrittsdüse 3 zugewandte Seite der Steckhülse 5 an einem Dichtring 8 auf.The plunger 4 closes the outlet nozzle 3 . The receptacle 5 and the annular piston 6 have reached their end position. In this end position, the side of the plug-in sleeve 5 facing the outlet nozzle 3 is seated on a sealing ring 8 .
Phase b zeigt den Beginn des Dosiervorganges. Die Steckhülse 5 bewegt sich entlang der Achse 7 von der Austrittsdüse 3 weg, während der Stößel 4 die Austrittsdüse 3 weiter abdichtet. In Phase c bewegt sich der Ringkolben 6 entlang der Achse 7 innerhalb der Steckhülse 5 und saugt so die abzufüllende Flüssigkeit F in die Steckhülse 5. Durch den Hub des Ringkolbens 6 wird bestimmt, wieviel Flüssigkeit F aus dem Vorratsbehälter in die Steckhülse 5 eingesaugt wird.Phase b shows the start of the dosing process. The plug-in sleeve 5 moves along the axis 7 away from the outlet nozzle 3 , while the plunger 4 further seals the outlet nozzle 3 . In phase c, the annular piston 6 moves along the axis 7 within the plug-in sleeve 5 and so sucks the liquid F to be filled into the plug-in sleeve 5 . The stroke of the annular piston 6 determines how much liquid F is sucked into the receptacle 5 from the reservoir.
In Phase d werden die Steckhülse 5 und der Ringkolben 6 gemeinsam, d. h. ohne daß sie sich relativ zueinander bewegen entlang der Achse 7 in Richtung Austrittsdüse 3 bewegt, bis der Rand der Steckhülse 5 an dem Dichtring 8 anliegt.In phase d, the receptacle 5 and the annular piston 6 are moved together, ie without moving relative to one another along the axis 7 in the direction of the outlet nozzle 3 until the edge of the receptacle 5 lies against the sealing ring 8 .
In Phase e wird der Stößel 3 von der Austrittsdüse 3 zurückgezogen und gibt diese frei. Anschließend fährt der Ringkolben 6 in Richtung Austrittsdüse 3 und fördert so die Flüssigkeit F durch die Austrittsdüse 3. In dieser Phase zeigt sich die Bedeutung des Dichtrings 8.In phase e, the plunger 3 is withdrawn from the outlet nozzle 3 and releases it. The annular piston 6 then moves in the direction of the outlet nozzle 3 and thus conveys the liquid F through the outlet nozzle 3 . This phase shows the importance of the sealing ring 8 .
Hierdurch wird der durch die Steckhülse 5 und den Kolben 6 gebildete Raum gegenüber dem Vorratsbehälter 2 abgedichtet. Somit wird verhindert, daß die in den Behälter zu überführende Flüssigkeit wieder zurück in den Vorratsbehälter 2 gelangt. Gleichzeitig wird so die Austrittsdüse auch gegenüber dem Vorratsbehälter 2 abgedichtet. Hierdurch wird verhindert, daß zusätzlich zu der im Inneren der Steckhülse 5 befindlichen Flüssigkeit zusätzliche Flüssigkeit direkt aus dem Vorratsbehälter durch die Austrittsdüse 3 hindurch in den zu befüllenden Behälter gelangt.As a result, the space formed by the plug-in sleeve 5 and the piston 6 is sealed off from the storage container 2 . This prevents the liquid to be transferred into the container from getting back into the storage container 2 . At the same time, the outlet nozzle is also sealed off from the storage container 2 . This prevents that, in addition to the liquid inside the plug-in sleeve 5, additional liquid gets directly from the storage container through the outlet nozzle 3 into the container to be filled.
Durch die Bewegung des Ringkolbens 6 wird es möglich, auch höher viskose Flüssigkeiten dosiert abzufüllen. Auch Feststoffe in der Flüssigkeit stören nicht, solange die Festkörper nicht größer sind als der Durchmesser der Austrittsdüse 3 oder der Freiraum zwischen dem Stößel 4 und der Steckhülse 5.The movement of the annular piston 6 makes it possible to dispense even highly viscous liquids in a metered manner. Solids in the liquid also do not interfere as long as the solids are not larger than the diameter of the outlet nozzle 3 or the free space between the plunger 4 and the plug-in sleeve 5 .
Die erfindungsgemäße Vorrichtung ist insbesondere geeignet zum Abfüllen von Produkten, in denen sich noch feste Stücke befinden, es können jedoch auch beliebige andere Flüssigkeiten mit hoher Viskosität verarbeitet werden.The device according to the invention is particularly suitable for Filling of products in which there are still solid pieces any other liquids can be processed with high viscosity.
