Die Erfindung bezieht sich auf eine Vakuum-Greifvorrichtung, die an Krane oder sonstige Hebevorrichtungen angebracht werden kann.The invention relates to a vacuum gripping device, which can be attached to cranes or other lifting devices.
Bekannt sind Vakuum-Greifvorrichtungen dieser Art, die aus einer mit der Hubvorrichtung oder einem Hubgerät zu verbindenden Platte bestehen, zwei auf dem Boden der Platte angeordneten, einander mit Abstand umgebenden, in sich geschlossenen und eine innere und eine äußere Kammer begrenzenden elastischen Dichtlippen, mit einem durch die Platte zur inneren Kammer führenden Vakuumrohr und mit Durchgängen in der die innere Kammer begrenzenden Dichtlippe, die beide Kammern miteinander verbinden. Are known vacuum gripping devices of this type, which consist of a lifting device or a Lifting device to be connected plate consist, two arranged on the bottom of the plate, with each other Distance surrounding, self-contained and an inner and an outer chamber delimiting elastic Sealing lips, with a vacuum tube leading through the plate to the inner chamber and with Passages in the sealing lip delimiting the inner chamber, which connect the two chambers with one another.
Bei der praktischen Anwendung einer solchen Greifvorrichtung senkt man diese so weit auf die Last ab, bis die beiden Dichtlippen auf deren Oberfläche aufliegen. Darauf wird die innere Kammer durch Anschluß des Vakuumrohres an eine Saugpumpe od. dgl. evakuiert. Der dabei in der inneren Kammer entstehende Unterdruck wird durch die die beiden Kammern miteinander verbindenden Durchgänge in die äußere Kammer übertragen. Der sich dann in beiden Kammern ausbildende Unterdruck saugt die Platte der Greifvorrichtung an die Oberfläche der Last an. Die Elastizität der Dichtlippen ermöglicht diese Bewegung. Wesentlich ist dabei, daß sich die Platte auch an Lasten mit rauher Oberfläche dichtend ansaugt. In the practical application of such a gripping device, it is lowered so far onto the load until the two sealing lips rest on their surface. Then the inner chamber is connected of the vacuum tube to a suction pump or the like. Evacuated. The resulting in the inner chamber Negative pressure is created through the passages connecting the two chambers into the outer chamber transferred. The negative pressure that then forms in both chambers sucks the plate the gripping device to the surface of the load. The elasticity of the sealing lips enables this movement. It is essential that the plate also sucks in a sealing manner against loads with a rough surface.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß der wirksame Gesamtquerschnitt der Durchgänge von der inneren zur äußeren Kammer kleiner als der Querschnitt des Vakuumrohres ist.To solve this problem, the invention provides that the effective total cross-section of the passages from the inner to the outer chamber is smaller than the cross section of the vacuum tube.
In der Praxis wirkt sich dies wie folgt aus: Bei An-In practice, this has the following effects: When arriving

From the outer Compared to the cross-section of the chamber, passages have only a moderate flow through the passages The vacuum tube introduces such a large effective proportion of air into the inner chamber, since total cross-section that both chambers are practically 35 the effective total cross-section of these passages evacuated at the same time or, in the case of a rough surface, is smaller than the cross-section of the vacuum tube. area of the load should be evacuated. The plate in the inner chamber must therefore be the negative pressure will then not occur faster on the load surface than it would be caused by a subsequent flow of sucked, as the resulting vacuum is constantly due to air from the outer chamber into the inner chamber the surface roughness existing 40 can be incomparable.
