8. A degripping apparatus comprising:
-
an attaching member fixed to an endless recirculating traveling conveyor; a rotational shaft supported on the attaching member; a gripping arm pivoted on the rotational shaft, extending in a direction where the arm intersects with the rotational shaft, the gripping arm being turned in accordance with the rotation of the rotational shaft; an article gripping mechanism provided on one end of the gripping arm, and including a pair of opposing gripping members provided pivotally on the one end of the gripping arm, the gripping members having connecting portions meshing with each other, whereby when one of the gripping members is turned, the other gripping member is also turned so that the gripping members open and close; a drive arm fixed to the rotational shaft, extending in the direction where the drive arm intersects with the rotational shaft, having engaging means at one end thereof and rotating the rotational shaft by the turning of the drive arm, whereby when the gripping arm is turned by means of the rotation of the rotational shaft from a position where the gripping arm is parallel to the direction of movement of the traveling means to a position where the gripping arm is perpendicular to the direction of movement of the traveling means, the gripping mechanism degrips the article; an actuating member provided pivotally on one end of the gripping arm, and having one end engaged with one opposing gripping member to turn said one opposing gripping member; and a control member for actuating the actuating member, having a control member provided pivotally on the gripping arm at one end thereof and spring means for elastically urging the actuating member against the gripping arm in a direction which brings the gripping members into an opened state. - View Dependent Claims (9, 10)
