Description
Die Erfindung bezieht sich auf die weitere Ausbildung eines Selbstgreifers nach Patent 479 269. Um die Raumbeweglichkeit dieses Selbstgreifersystems so weit zu erhöhen, daß auch sehr grobstückiges Material erfaßt werden kann, ohne ein Abdrehen oder eine seitliche Verbiegung der Greiferarme befürchten zu müssen, sind der Erfindung gemäß die Greiferarme mit der Unterflasche durch Kugelgelenke verbunden, so daß sie sich in weitem Maße nach der Seite hin zwanglos verstellen können.The invention relates to the further development of a self-gripper according to the patent 479 269. To increase the spatial mobility of this self-gripping system to such an extent that Even very chunky material can be detected without turning or lateral Having to fear bending of the gripper arms, according to the invention, the gripper arms with the bottom block are through Ball joints connected so that they adjust freely to the side to a large extent can.
Auf der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung dargestellt, Es zeigt Abb. 1 einen Teil der Unterflasche des Selbstgreifers mit einem daran angelenkten Greiferarm. Abb. 2 ist die zugehörige Draufsicht, während die Abb. 3 bis 8 Einzelheiten zeigen.The drawing shows an example embodiment of the invention, Fig. 1 shows part of the lower block of the self-gripper with a hinged one Gripper arm. Fig. 2 is the associated top view, while Figs. 3 to 8 show details demonstrate.
Es ist α die Unterflasche des Selbstgreifers und b einer der daran angelenkten Greiferarme. Der Gelenkpunkt des Greiferarmes b an der Unterflasche wird durch einen kugelförmigen Ansatz c gebildet, der in Lagerkörpern d und e mit entsprechenden kugelschalenförmigen Ausnehmungen d' und e' gelagert ist. Die beiden Lagerkörper d und e passen übereinander und werden gemeinsam an dem Rollenkasten α durch Schrauben f festgehalten. Um ein seitliches Verschwenken der Greiferarme innerhalb weiter Grenzen zuzulassen, sind die Lagerkörper mit entsprechend breiten Aussparungen g und h versehen.It is α the lower block of the self- gripper and b one of the gripper arms linked to it. The articulation point of the gripper arm b on the bottom block is formed by a spherical extension c , which is mounted in bearing bodies d and e with corresponding spherical shell-shaped recesses d ' and e' . The two bearing bodies d and e fit one above the other and are held together on the roller box α by screws f . In order to allow lateral pivoting of the gripper arms within wide limits, the bearing bodies are provided with correspondingly wide recesses g and h .
An der Unterflasche sind sämtliche Greiferarme in dieser Weise angelenkt und in der bekannten Weise durch Schubstangen mit der Oberflasche verbunden, die ihrerseits an den Greiferarmen bei i angelenkt sind. Die Gelenke erhalten ebenfalls so viel freies Spiel, daß die Verstellung der Greiferarme zum Aufgreifen grobstückigen Materials ausreicht.All the gripper arms are hinged to the lower block in this way and are connected in the known manner to the upper block by push rods, which in turn are articulated to the gripper arms at i. The joints are also given so much free play that the adjustment of the gripper arms is sufficient to pick up coarse material.
