Adjustment Procedures
1. To remove chuck inversion cylinder
3 of knuckle 2, cylinder 1 and two setscrews 4.
2. In the state that the button chuck is level, loosen nut
adjust so that the clearance between knuckle
1 is 22 ± 0.5 mm.
3. Loosen setscrews 7 in respective sensors 6 located on the
sides of respective cylinders
position where they go off and light, and further move by 0.5
to 1 mm, and tighten setscrews
to the arm on the right-hand side in the figure when the chuck
is level, and sensor 6 on the left-hand side when the chuck is
vertical respectively.
4. Supply air and adjust with the speed controller so that the
motion is not shocked largely at the time of inversion.
5. Adjust the installing dimension of sensor
cylinder 1 1 (vertical) to 4 mm from the top end. (Reference
dimension)
6. Adjust the installing position of sensor
cylinder 2 1 (level) to 15 mm from the top end. (Reference
dimension)
