Definitions
- the invention relates to a gripping device for at least 2 different gripping goods.
- Gripping devices are designed such that the gripping surfaces hold the gripping material over a contact surface. A line contact could lead to a deformation of the gripping material.
- the gripping levers are adapted to the gripping material. If the gripping device, instead of a small pipe, grips a larger pipe surface, the gripping lever with the gripping surface is exchanged according to the prior art.
- the invention has for its object to provide a universal tool for several items to be gripped and also to avoid set-up time.
- the gripping lever of a gripping device has a gripping surface with two faces, wherein the first faces of the gripping surfaces may comprise a first gripping surface, while the other faces of the gripping surfaces may comprise a different gripping surface ,
- the FIG. 1 shows a gripping device with two gripping levers 1, wherein each of the gripping levers 1 has a gripping surface 2.
- the gripping device has a further illustrated adjusting device for moving at least one of the gripping levers 1.
- the right gripper lever 1 has a pivot point 7 around which the gripping lever 1 can be rotated.
- the gripping surfaces 2 are each divided into two parts: centrally in the gripping surfaces 2 is in each case a first partial surface 5, which are surrounded by respective second partial surfaces 6.
- a first gripping material 3 is held flat by the first partial surfaces 5 of the gripping surfaces 2.
- the two gripping levers 1 form a relatively small angle.
- FIG. 2 shows the same gripping device, wherein the second partial surfaces 6 hold a second, larger gripping product 4 area.
- the right gripping lever 1 is rotated counterclockwise about the pivot point 7, so that the two gripping levers 1 in comparison to FIG. 1 form a relatively large angle.
- At least one of the gripping levers can be moved linearly instead of by rotation.
- first partial surfaces 5 in the middle region of the gripping surfaces 2 can comprise the smallest gripping material 3 flatly, and the second partial surfaces 6 are arranged around this central region for covering larger gripping products 4 in a planar manner.
- the invention is not limited to two different gripping goods 3, 4, but can be continued as desired, wherein it makes sense that from the central region outwardly several areas for planar gripping larger gripping goods 3, 4 are arranged, wherein from the inside out the areas for larger and larger items 3, 4 are arranged.
- the adjusting device adjusts the gripping levers 1 in such a way that the gripping lever 1 and / or its angle increases relative to each other with the gripping material 3, 4 becoming larger in area.
- the gripping device is usually in a more complex machine, which also supplies the gripping material 3, 4 and further promotes integrated. Furthermore, the gripping device can be located on a gripper arm, not shown, which moves the two gripping levers 1.

Abstract
Description
Die Erfindung bezieht sich auf eine Greifvorrichtung für mindestens 2 unterschiedliche Greifgüter.The invention relates to a gripping device for at least 2 different gripping goods.
Greifvorrichtungen sind derart gestaltet, dass die Greifflächen das Greifgut über eine Berührfläche halten. Eine Linienberührung könnte zu einer Verformung des Greifgutes führen. Dabei sind die Greifhebel an das Greifgut angepasst. Soll die Greifvorrichtung anstelle eines kleinen Rohres ein größeres Rohr flächig greifen, so wird gemäß dem Stand der Technik der Greifhebel mit der Greiffläche ausgetauscht.Gripping devices are designed such that the gripping surfaces hold the gripping material over a contact surface. A line contact could lead to a deformation of the gripping material. The gripping levers are adapted to the gripping material. If the gripping device, instead of a small pipe, grips a larger pipe surface, the gripping lever with the gripping surface is exchanged according to the prior art.
Der Erfindung liegt die Aufgabe zugrunde, ein Universalwerkzeug für mehrere Greifgüter zu schaffen und hierbei zudem Rüstzeit zu vermeiden.The invention has for its object to provide a universal tool for several items to be gripped and also to avoid set-up time.
Dies wird gemäß den Merkmalen des unabhängigen Anspruchs 1 dadurch gelöst, dass die Greifhebel einer Greifvorrichtung über eine Greiffläche mit zwei Teilflächen verfügt, wobei die ersten Teilflächen der Greifflächen ein erstes Greifgut flächig umfassen können, während die anderen Teilflächen der Greifflächen ein anderes Greifgut flächig umfassen können.This is achieved according to the features of the
Vorteilhafte Ausgestaltungen der Erfindung ergeben sich durch die Merkmale der abhängigen Ansprüche.Advantageous embodiments of the invention will become apparent from the features of the dependent claims.
Die Erfindung wird nun anhand der Figuren detailliert erläutert. Hierbei zeigen

FIG. 1 the gripping device in engagement with a small gripping goods and -
FIG. 1 the same gripping device in engagement with a larger gripping material.
Die
Zum Greifen wird jeweils nur der rechte Greifhebel 1 im Gegenuhrzeigersinn geöffnet, das Greifgut 3, 4 an den linken Greifhebel 1 angelegt und das Greifwerkzeug durch Drehen des rechten Greifhebels 1 im Uhrzeigersinn geschlossen.For gripping only the
Erfindungsgemäß können nicht nur Rohre flächig gehalten werden. Dies ist auch mit anderen Querschnitten möglich.According to the invention not only pipes can be kept flat. This is also possible with other cross sections.
Auch kann zumindest einer der Greifhebel statt durch eine Drehung linear verschoben werden.Also, at least one of the gripping levers can be moved linearly instead of by rotation.
Generell ist besonders vorteilhaft, wenn die ersten Teilflächen 5 im mittleren Bereich der Greifflächen 2 flächig das kleinste Greifgut 3 umfassen können und um diesen mittleren Bereich die zweiten Teilflächen 6 zum flächigen Umfassen größerer Greifgüter 4 angeordnet sind. Die Erfindung ist nicht auf zwei unterschiedliche Greifgüter 3, 4 beschränkt, sondern kann beliebig fortgesetzt werden, wobei es dabei sinnvoll ist, dass vom mittleren Bereich ausgehend nach außen mehrere Bereiche zum flächigen Umfassen größerer Greifgüter 3, 4 angeordnet sind, wobei von innen nach außen die Bereiche für stets größere Greifgüter 3, 4 angeordnet sind. Die Verstelleinrichtung verstellt die Greifhebel 1 derartig, dass mit größer werdendem Greifgut 3, 4 zum flächigem Umfassen der Abstand der Greifhebel 1 und / oder deren Winkel zueinander zunimmt.In general, it is particularly advantageous if the first
Prinzipiell ist es jedoch auch möglich, dass die Greifflächen 2 nebeneinander unterschiedliche Teilflächen 5, 6 aufweisen; hierbei fällt jedoch zwangsläufig der Greifhebel 1 länger aus.In principle, however, it is also possible that the
Die Greifvorrichtung ist üblicherweise in eine komplexere Maschine, welche das Greifgut 3, 4 auch zuführt und weiterfördert, eingebunden. Ferner kann sich die Greifvorrichtung an einem nicht dargestellten Greifarm befinden, welcher die beiden Greifhebel 1 bewegt.The gripping device is usually in a more complex machine, which also supplies the gripping
