PURPOSE:To enable the revolving operation fore and aft of the transfer head provided at one end of a revolving lever by the same driving means by providing a tensile spring engaging a cam follower with the U shaped groove of a plate cam and a driving means for moving the revolving lever in the fore and aft direction at its rotation center. CONSTITUTION:In accordance with a revolving lever 1 being moved in fore and aft direction by a driving means, the transfer head(chuck) 2 provided at one end of this revolving lever 1 is moved in the fore and aft direction. At this time the cam follower 3 provided at the other end of the revolving lever 1 is fitted into the U shaped groove (e) of the plate cam 4 and brought into contact each other by a tensile spring 5. With this fitting the revolving lever 1 is then subjected to a revolving movement in an arrow mark (f) direction centering around a rotating fulcrum 0. Consequently, the transfer head part 2 can be subjected to fore and aft and revolving movement by the same driving means. |
