1. To remove chuck inversion cylinder , remove hinge screw of
knuckle , cylinder and two setscrews .
2. In the state that the button chuck is level, loosen nut and adjust so
that the clearance between knuckle and cylinder is 22
±
0.5
mm.
3. Perform chuck mechanical adjustment vertically first and then hori-
zontally.
o In vertical adjustment, make the chuck vertical with holding the
button gauge by operating on the chuck adjustment screen of the
operation panel.
At this moment, make the button gauge parallel with the needle
after loosening the screws
(2 pieces).
Perform horizontal adjustment, next.
o Make the chuck horizontal by operating on the chuck adjustment
screen of the operation panel, and make the button gauge parallel
with the throat plate by adjusting the horizontal stopper .
4. Loosen setscrews in respective sensors located on the sides
of respective cylinders , adjust the sensors to the position where
they go off and light, and further move by 0.5 to 1 mm, and tighten
setscrews
. Adjust sensor attached to the arm on the right-hand
side in the figure when the chuck is level, and sensor on the left-
hand side when the chuck is vertical respectively.
5. Supply air and adjust with the speed controller so that the motion is
not shocked largely at the time of inversion.
6. Adjust the installing dimension of sensor of chuck inversion cylin-
der 1 (horizontal) to 4 mm from the top end. (Reference dimen-
sion)
7. Adjust the installing position of sensor of chuck inversion cylinder
2 (vertical) to 15 mm from the top end. (Reference dimension)
o When the position is improper,
error occurs.
o Do not adjust except when the
motion is shocked largely since
adjustment has been performed
at the time of delivery.
