4. Loosen the mounting bolts shown in the figure below, then adjust the lever height

until there is a 1.9 mm gap (use a thickness gauge) between the bottom of the

mechanical valve and the lever. At this stage, the spring pusher is pressed down

0.1 mm.

Note: Do not touch the speed regulator.

The blow air pressure is set to 15.0 ± 0.5 kPa (13st: 7.0 ± 0.5 kPa). The user should not

change the setting, as a manometer is required for the adjustment.

1.12 Reverse-theta Mechanism (Station 10)

Point

This mechanism reverses the nozzle rotation which occurred at the station 9 part

placement. The nozzle is returned from that part placement angle by the amount of

rotation which occurred at stations 2 and 8.

1.12.1 Clutch Meshing Check

Perform this check on the low-pressure nozzle.

Note: The low-pressure nozzle refers to the placing head (out of the 16) that receives the weakest

pushing pressure. Use the low-pressure nozzle for meshing checks at stations 2, 8 and 10.

1. Press the EMERGENCY STOP button to take the 200V down to 100V.

WARNING

• Always be sure to cut off the 200V power before carrying

out any work.

• Exercise extreme caution when working on the machine if

the cam is not at its origin (0 deg.). Recoil of the cam

axis can endanger the operator.

2. Set the cam angle to 0 degrees, then turn the station 10 solenoid valve on to work

the cam lever.

3. Set the dial gauge to the bottom of the nozzle shaft brake.

4. Use the cam handle to rotate the cam to 200°.

5. Ensure that the clutches mesh properly and the placing head assembly deflects the

dial gauge by 0.30 ~ 0.35 mm as illustrated below.

1.12.2 Clutch Meshing Check Sensor Position Adjustment

1. Press the EMERGENCY STOP button to take the 200V down to 100V.

WARNING

• Always be sure to cut off the 200V power before carrying

out any work.

• Exercise extreme caution when working on the machine if

the cam is not at its origin (0 deg.). Recoil of the cam

axis can endanger the operator.

2. Use the cam handle to rotate the cam to 200°.

3. Execute inching to align the RQ-axis with the RQ-data position.

4. Make sure the clutches engage properly. Adjust the height of Bracket A so that

Gap C in the figure is 0.2 mm.

5. At this position, adjust the position of Bracket B so that the sensor beam hits the

hole on the dog.
