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.

1.12.3 Clutch Meshing Check Sensor Amp Adjustment

Adjust the sensor amp so that it goes off when the clutches mesh properly and it goes on

when the clutches do not mesh properly and the dog is pushed down.

Remove the cover of the amp and follow the procedures below.

Note: Be careful not to drop the cover inside the machine.

1. Set the setting switch to “D ON”.

2. Set the mode selector switch to “SET”. The digital display will then indicate “1”.

3. With the clutch engagement sensor on (sensor is detecting the hole in the dog),

press the [TUNING] button. The digital display will then indicate “2”.

4. With the clutch engagement sensor off (sensor is not detecting the hole in the dog),

press the [TUNING] button. The digital display will then indicate “9”.

5. Set the mode selector switch to “RUN”.

6. After completing the amplifier setting procedure, verify that the digital display

indicates 0 ~ 1 when the sensor is on, and 8 ~ 9 at all other times.
