PROBLEM TO BE SOLVED: To solve the problem that an oscillation lever interferes with the other constituent element and a cam at a driving part must be replaced because a material feeding amount can not be adjusted in a wide range in a mechanism for adjusting the material feeding amount of a gripper feed device. SOLUTION: A shaft hole 41a of the oscillation lever 41 is composed as follows. A slot hole, by which an insertion position of an oscillation shaft 42 can be adjusted, is formed on the axis of both arm parts 41b, 41c. A perpendicular female screw is engraved to the oscillation shaft 42 at a part inserted into a body part of the oscillation lever 41. A rotatable adjusting bolt 45, which is screwed to the female screw of the oscillation shaft 42, is provided to the body part of the oscillation lever 41. The oscillation lever 41 is moved along the slot hole to the oscillation shaft 42 by the adjusting bolt 45. Therefore, it is possible to adjust the material feeding amount by adjusting a lever ratio of the primary side and the secondary side of the oscillation lever 41. COPYRIGHT: (C)2005,JPO&NCIPI
