1.11 Mechanical Valve Switching (Station 9)

Point

The nozzle vacuum goes from ON to OFF with the movement of the mechanical valve at

station 9. Vacuum pressure inside the nozzle is released for part placement when the

valve closes. Ensure the part is placed on the production board.

1.11.1 Checking the Position of the Pin Bracket

1. Press the EMERGENCY STOP button to turn off the 200V power, leaving only the

100V power on.

WARNING

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

out this work.

2. Ensure that distance A (as seen in the figure below) is 8.9 mm for all heads. Use a

special jig (Z9526DCPJ0371) to check this distance.

1.11.2 Valve Switching Lever Height Adjustment

This adjustment should be performed on the reference head after completing

adjustments to the vertical movement of the nozzle. (Refer to 1.10 “Nozzle Vertical

Movement During Placement” for details.)

The reference head can be identified by its height. All heads are measured with spools

lifted, and the lowest one is referred to as the reference head.

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°, then activate the place solenoid (Y035 ST9 PLACE SOL

ENGAGED) at station 9 to work the lever.

3. Use the cam handle to rotate the cam to 180°.

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.
