[13-25] Shuttle Jaw Front to Back Angle of Orientation Adjustment
Set the dial gauge needle on the inside surface of the stationary claw and move it up and down
in the Z-direction. Then twist the shuttle bar mount to adjust the jaw so that the angle of
orientation from the top of the claw to the bottom is within the allowable tolerance.
Tolerance: Within +/- 0.1 mm
[13-26] Shuttle Jaw Parallel Adjustment
Use the dial gauge set on the inside of the stationary side claw in the previous item. This time
move the dial gauge in the X-direction to measure the parallelism of the jaw. If the difference at
each end exceeds the allowable tolerance then the shuttle bar must be replaced. When the
shuttle bar is replaced not only must parallel adjustment be performed but the angle of
orientation in the previous item must be adjusted again as well.
Tolerance: Within +/- 0.2 mm
Tolerance : within +/-0.2mm

13-27] TZ-axis Zero Set Position Adjustment
1) Rotate the ball screw by hand and move the two spline shaft nuts to the mechanical stopper
positions.
2) Loosen the span ring on the belt pulley mechanism located on the underside of the ball
screw. If the spann ring is difficult to loosen, move the bolt to the adjacent loosening hole as
shown in the figure and fasten the bolt in the hole.
3) Use the inching button to move the TZ-axis –1,000 pulses (–10 mm). In this position wrap
the belt around the pulley, tighten the spann ring and use the belt tension pulley to adjust
the tension.
Note: In some instances the pulley may drop down as the ring is tightened. Push the pulley
up to the highest point and then tighten the spann ring bolt.
Belt tension: 52.10 Hz ~ 62.10 Hz
4) Install the zero set dog (also serves as TZ-axis interlock) that was removed in an earlier
process. Move the TZ-axis via inching to a servo count of + 400 (position 14 mm from the
mechanical stopper). Move the zero set sensor to adjust it so that it comes on at this position.
5) Next, move the TZ-axis to turn the sensor off and then back on to verify the servo count value.
6) Lastly install the TY-axis interlock (also serves as set pitch) dog. Raise the TZ-axis via
inching and adjust the bracket position so that none of the interlock sensors and dogs
interfere with each other.
Note: If the TZ-axis interlock dog is moved the TZ-axis zero set sensor must be adjusted
again.
[13-28] Zero_Offset_TZ Measurement and Re-calibrating Zero Setting
Move the TZ-axis up 1 mm (100 pulses) from the bottom mechanical stopper. The servo count
value at this time becomes the Zero_Offset_TZ value. After the value is entered at the machine or
transmitted from F4G, cut the power to the machine, reboot and then carry out zero set again.
Note: After zero set is completed the machine moves not to the zero set complete position but to
the position specified by Zero_Offset_TZ and the servo count value is reset to zero. Before
proceeding to the next item be sure to cut the power and carry out zero set again.
Adjust so that the
zero set sensor comes
on when the TZ-axis
count is + 400 pulses.

[13-29] Tray Holder Positioning Adjustment
1) When the tray holder pops out of the MTU, press the tray holder into the MTU by hand.
While checking that the tray holder does not interfere with any of the components such as
the rollers, move the fifth level tray holder to the center of the MTU by inching the TZ-axis.
2) Open the safety door and push all of the tray holders to the guide rail in the back of the unit.
Use a long scale on the portion of the tray holder that makes contact with the white plastic
guide attached to the door in order to verify which tray is entered the farthest back in the unit.
At this time verify that the deviation between all of the tray positions is not more than 1 mm.
3) Loosen the mounting bolts of the white plastic guide attached to the door.
4) Close the door and adjust the gap between the tray holder and guide that was verified
in step 2, within a range between 0.5 mm and 1 mm. Then secure the mounting bolts.
5) Move the TZ-axis up and down and verify that the gap between the tray holder and guide
lies within the range used in adjustment (0.5 mm ~ 1mm) at any position.
[13-30] Re-calibrating Zero Setting Prior to Proper Data Measurement.
[13-31] Remover_Position_X,Y,Z
1) Attach the measurement jig to the remover station, and then turn I/O Y000: REMOVER UP
on to raise the remover station.
2) Press EMERGENCY STOP and move the head placement hook mechanism by hand to the
station position.
3) Raise the Z-axis by hand and fine adjust the XY axes so that the pin on the placement hook
mechanism fits smoothly into the hole in the jig. This position becomes Remover_Position_X
and Y.
4) Lower the Z-axis from the Remover_Position_X and Y position to press the placement hook
pin into the jig hole. Lower the Z-axis further until the chuck-positioning pin is depressed 1
mm (spring return of 1mm). This position is the Remover_Position_Z value.
[13-32] Remover Lubrication
Apply grease (Daphne Eponex #2) to the placement hook mechanism pin and plate spring
such that the grease does not splatter.
Guide rail
Move the white plastic guide to adjust.
Tray holder
Guide rail
Move the fifth level
tray so that it comes to
the center of the MTU.
Adjust the gap between
the tray holder and the
plastic guide to 0.5 mm.
