4.10 [PQ] [PRQ] Origin Position Adjustment

1. Set the cam angle to 0 degrees. Loosen the screw bolts of each timing pulley. Confirm that the

rotor faces the origin position. (Origin position means that the clutch rotor faces the center of the

index unit.)

2. Calibrate the timing belt tension of PQ and PRQ.

PQ1,2 (Appropriate value 188 ± 20Hz)

PRQ1 (Appropriate value 181 ± 20Hz)

PRQ2 (Appropriate value 376 ± 20Hz)

3. Calibrate at the positions shown in the right

illustration. Adjust from ? to ? for both

PQ and PRQ if necessary.

4. Set a jig to nozzle shaft A. Set the cam angle to 0

degrees. Turn ON the solenoid valve.

Y02C PRQ ROT SOL ON

5. Set the cam angle around 250 degrees (after rotating to 90, 270 degrees). Align using a dial

indicator. Tighten a screw bolt temporarily.

6. Set the cam angle to 0 degree. Switch the solenoid valve. Confirm the scale when rotating to 90

and 270 degrees. Balance and secure the timing pulley.

Y024 PQ ROT 90 DEG

Y025 PQ ROT 270 DEG

Y02E PRQ ROT 90 DEG

Y02F PRQ ROT 270 DEG

Balance is the key point. Adjust both 90 and

270 degree movement to balance equally.

4.11 Station 18 Nozzle Changer Adjustment

NC axis Zero setting

1. Lower the NC servo amp gain to 150 [PN100]

2. Remove the zero setting flag from the drive gear.

3. Remove the timing belt

4. Set the cam to 0 degrees, and complete zero setting.

5. Attach the timing belt so that zero setting completes where

the rotor for the NC clutch faces horizontally. Align the flag

within the center of the sensor

6. Return the NC servo amp gain to 250. [PN100]

SX00E NC AXIS ZERO

Alignment and Belt Tension

1. Align the NC clutch using (Jig no.: 71615WPJ0281) at 200 degrees.

Check the belt tension at the same time.

(Changing the belt tension will shift the alignment.)

(Appropriate value --- 142 +/- 5Hz)

Caution: The alignment jig spans 3 nozzle shafts. Do not

move the jig to the stations where the nozzle shaft moves up and down.

Stroke adjustment

1. After alignment, set a nozzle holder on nozzle shaft, A.

Set the cam angle at station 1 to 200 degrees, and align the

nozzle holder.

2. Move the aligned nozzle holder between station 17 and 18

at 0 degrees. Turn the solenoid valve for the nozzle changer

ON.

3. Turn the index and set the cam angle to 128 degrees.

Adjust the rod so that the nozzle holder clutch pushes

the nozzle changer clutch 0.01 to 0.05mm. (0.03 best)

(The rod length within the cam box must be set to 21mm.)

Y02A NOZ SOL ON

4. For the floating angle of the rod-end under the cam box,

fix where it is parallel to the lever and set the rod to 21mm

at the 18

station lever.

NC Data Calibration

1. Set the cam angle to 0 degrees. Turn ON the NC valve.

2. Zero set the NC-axis. Turn OFF the 200V and rotate the index to set the cam angle to 128

degrees.

3. Engage the NC clutch rotor with the nozzle holder clutch.

4. NC data --- Servo counter of the NC-axis where the clutch started engaging and

there is no play in the NC clutch rotate-direction. (It does not matter

whether “plus” or “minus” values are obtained. Take the lowest pulse

count value to get the clutch horizontal.)

4.12 Stations 17 and 19 Nozzle Type Check Sensor Adjustment

1. Confirm the alignment of each sensor bracket using an alignment jig.

Caution: The alignment jig spans 3 nozzle shafts. Do not move the jig to the stations where the

nozzle shaft moves up and down by nozzle up/down cam.

2. Move the fiber sensor to the end of bracket, and fix it there. (The clearance between the sensor

and dog is about 12mm.)

Setting the amplifier

1. Set a nozzle holder to the nozzle shaft. Set the cam angle to 200 degrees. Align the

nozzle holder at the 11

station in the Y direction. Turn OFF the 13 station valve and

remove the spring from the 12

station.

2. Select the 6th nozzle, ON, OFF, ON, and move the holder to station 17.

(Cam at 200 degrees.)

3. Set the mode changing switch for the nozzle type check sensor amplifier at station 17 to

“SET”, and press the “TUNING” button. (3 positions)

4. Select the 2nd nozzle, OFF, ON, OFF, and press the “TUNING” button. (3 positions)

5. Set the mode changing switch back to “ RUN”.

6. Digital display after amplifier settings;

( ON, OFF, ON) = (9, 0, 9)

( OFF, ON, OFF) = (0, 9, 0)

7. Adjust the nozzle type check sensor at station 19 in the same manner.
