3.20 Slider Height Adjustment for ST1, ST11
To set the slider height, it will be necessary to remove a shaft assembly. Choose any shaft other
than the “A” shaft for removal.
1. Move the shaft to be removed near ST11 and set the cam angle to 0 degrees. Place a
8mm spanner at position A and remove the 3mm socket hex bolt from the top of the
clutch. (fig. 38)
2. Remove the four retainers for the linear guide and disconnect the vacuum hose. Remove the
shaft assembly from the index unit.
3. With the Placing and Pick-up valves OFF, move the opening where the shaft was removed to
Station 11 and set the cam at 180 degrees. Check the flatness of the slider surface as
indicated in Fig. 39. (the flatness should be zero) Follow the same procedure for Station 1.
(Pick-up)
4. For stations 1 & 11, turn the cam to zero degrees and turn the placing solenoid ON.
Measure the slider height in relation to the cylindrical cam (with the cam at 10 degrees) as
illustrated in Fig. 40. (10 degrees allows sufficient clearance for the dial gauge)
Adjust the height of the slider for Stations 1 & 11 by adjusting the appropriate rod in the Cam
Box. After adjustment, rotate the cam a few times and return to check the value again. Once
complete, ensure the lock nut is securely tightened on the 1
st
and 11
th
station rods.

3.21 Station 1 Pickup Height Adjustment
1. Set the cam angle to 0 degrees and turn the 1st station pickup valve ON. (Y020)
2. Install a nozzle jig in nozzle holder, No.1. (fig.42) Set the cam to 175 degrees.
3. Loosen the cam lever stroke adjustment bolts and move the fulcrum (fig. 41) so the dial
gauge reads zero. (Zero indicates that the pickup height is 0.650mm.) The tolerance for
all shafts must be 0.65 +/- 0.05. (check all shafts)
4. After adjustment, go back and check that the slider height is within tolerance.
(0 +/-0.03mm)
Important
Whenever the pickup height is adjusted, the slider height must be checked again.
Adjust both the pickup height and slider height until they are both within tolerance.
Exercise extreme care when setting the pick-up height. Mis-adjustment can lead to
component cracking during pick-up.
3.22 Reattaching the Shaft Assembly
When the slider height adjustment has been completed, reattach the shaft in the reverse order as
it was removed.
1. Tighten the retainer installation bolts using a torque wrench as follows.
(Torque the top 3mm bolts to 2 N.m, Torque the bottom 4mm bolts to 4N.m)
2. Using the bar jig, re-install the shaft assembly and align the holder and clutch so the alignment jig
inserts smoothly between the holder and the clutch. (there should be NO resistance) It is
important for all shafts and clutches to be aligned properly in order to avoid problems later on.

3.23 Placing Height Z0 Calibration
IMPORTANT!!!!
Exercise extreme care when setting the Z-origin height. Mis-adjustment can lead to
component cracking during placement.
NOTE: Calibrate only after the ST11 slider height and main conveyor clamper claws have been
adjusted.
1. Turn the 11
st
solenoid valve ON at 0 degrees.
Y028 PLACE SOL ENGAGED
2. After the Z- Axis adjustment is completed, clamp the jig plate in the middle of the table, and install
the nozzle jig in the A holder.
3. Manually move the jig under the ST11, placing point.
4. Set the cam angle at 200 degrees to lower the nozzle jig. Manually raise the Z-axis so that the
nozzle jig is in contact with a feeler gauge jig (- 0.3mm). The Z-axis servo counter at this time is Z0.
Target: (5500 +/-300 pulses)
5. Calibrate “Z0” on the reference side, adjustable side and center of the jig plate. The deviation
between each measuring point should be within 50 pulses of each other.
6. Enter the average value (of the three measurement points) in the proper at the host PC.
7. Alternatively, clamp the XC/YC calibration plate in the center of the table. Raise the Z-axis until the
dial gauge deflects 0.03mm. The proper value will be the servo pulse count with the gauge
deflected 0.3, plus 1050 (thickness of the jig plate). This procedure works well resulting in basically
the same value as obtained using the procedure in steps 1 to 6.
