Further, by moving the core 40 to the left, the main taper core 38 is inserted into the core on the opposite side of the core 40, and the core 40 is fixed.

On the contrary, the action when the core 40 is detached is
The air cylinder 61 is operated in the opposite direction to move the rod 60 to the right. By this movement, the slave fixed base 51 moves to the right, and the stopper 59 'mounted on the slave fixed base 51 also moves to the right. Since there is a bite in the taper fitting, when the secondary taper core 55 moves to the right, the taper core with a weak bite comes off first. First, when the secondary taper core 55 is first detached, the stopper 59 'only moves the pin 56 in the elongated hole until S / 2 and the stopper does not operate. Therefore, the core 40 bites the taper core 38 and stands still. There is. Next, when the slave fixed base 51 moves more than S / 2, the stopper 59 '
Is pulled by the pin 56 and moves to the right. Therefore, the protrusion 58 of the stopper 59 'comes into contact with the right side of the follower groove 57 and moves the core 40 to the right. Therefore, the main taper core 38 separates from the core of the core 40. By this operation, core 4
0 separates from each taper core.

On the other hand, when the taper core 38 is detached first, the core 40 and the sub taper core 55 move to the right with the bite between them. At this time, when the slave fixed base 51 moves by 1/2 S, the end surface of the stopper 59 'comes into contact with the guide base cover 63. Further, if the slave fixed base 51 moves to the right, the stopper 59 'cannot move. Therefore, the slave groove 57 of the core 40 and the protrusion 58 of the stopper 59' that are going to bite into the slave rotation shaft 50 and try to move to the right. The cores 40 are pressed against each other to disengage from the driven shaft 50. Therefore, the core 40 separates from each taper core.
