Abstract

The shut-off valve for a suction cup (3) comprises a flexible tube (1) which fits on the end of the vacuum line. Sealing lips are molded on its lower end and it closes when the pressure on its outer walls exceeds a threshold value to cut off vacuum from the cup.

Description

In der Praxis befinden sich oft mehrere Sauger an einer Vakuumleitung. Fällt einer oder mehrere Sauger aus, bzw. liegen nicht dicht an der anzusaugenden Fläche an, so besteht die Möglichkeit, dass das Vakuum auch in den anderen Saugern zusammenbricht und das anzusaugende Werkstück nicht gehalten werden kann.In In practice, there are often several suckers on a vacuum line. Falls one or more suckers, or are not close to the sucked area on, so there is the possibility that the vacuum breaks down in the other suckers and that to be sucked workpiece can not be kept.

Im Produktkatalog der Festo-AG (2.4/30-1 Europaprogramm 97/98) wird ein Vakuumsaugventil beschrieben, bei dem ein Schwimmer durch den entstehenden Luftstrom gegen eine Dichkante gedrückt wird und somit den Luftstrom absperrt.in the Product catalog of Festo AG (2.4 / 30-1 European program 97/98) a vacuum suction valve is described in which a float through the emerging air flow is pressed against a Dichkante and thus the air flow shuts off.

In einer anderen Lösung ( DE 3902616 C2 ) wird ein Ventilschließkegel durch das Medium entgegen der Kraft einer Feder gegen einen Ventilsitz gepresst.In another solution ( DE 3902616 C2 ) a valve closing cone is pressed by the medium against the force of a spring against a valve seat.

In DE 3630758 C1 wird eine Vorrichtung beschrieben, wobei der als Kugel ausgebildete Schließkörper mit Durchgangsbohrungen versehen ist und sich beim Schließvorgang zahnstangengesteuert verdreht.In DE 3630758 C1 a device is described, wherein the closing body formed as a ball is provided with through holes and rotates rack-controlled during the closing process.

Nachteilig bei allen Lösungen ist, dass sich im Inneren der Ventile bewegliche Teile befinden, die aufgrund von Passungen und Führungen sehr empfindlich gegen Verschmutzung und Feuchtigkeit sind.adversely in all solutions is that there are moving parts inside the valves, due to fits and guides are very sensitive to pollution and moisture.

Ziel der Erfindung ist es, ein Strömungssperrventil zu schaffen, welches unempfindlich gegenüber Verschmutzung und einfach im Aufbau ist und flüssige, gasförmige oder ein Gemisch aus beiden geeignet ist.aim The invention is a flow check valve to create which insensitive to pollution and easy is under construction and liquid, gaseous or a mixture of both is suitable.

Erfindungsgemäß wird das Problem dadurch gelöst, dass als Absperrorgan ein elastisches Formstück verwendet wird, welches an mindestens einer Seite Dichtlippen ausweist, die bei zulässigem Förderstrom geöffnet sind, sich bei erhöhtem Förderstrom aneinanderlegen und somit diesen stark drosseln, bzw. absperren und sich bei Verringerung des Förderstromes durch die Elastizität des Formstückes wieder öffnen.According to the invention Problem solved by that as an obturator, an elastic fitting is used, which on at least one side identifies sealing lips, the permissible flow open are at elevated flow put on each other and thus restrict this strong, or shut off and in reducing the flow rate through the elasticity open the fitting again.

Ein Ausführungsbeispiel der Erfindung wird anhand der 1, 2, 3, näher erläutert.An embodiment of the invention will be described with reference to 1 . 2 . 3 , explained in more detail.
