5. Place a dial gauge on the top end of the cam lever and set the gauge reading to “0”. In this condition, the cam axis will be at its 180-degree position, and the nozzle UP/DOWN rod will be at its DOWN limit position. V…

1.10.3 Adjusting the Nozzle DOWN Limit Sensors

The nozzle DOWN limit sensor which detects the down limit position of the nozzle

UP/DOWN rod is mounted inside the cam box. Adjust the mounting position of this

sensor so that it switches ON when the nozzle is at its DOWN limit position.

Note: When performing the DOWN limit sensor adjustment after the UP limit sensor adjustment,

remove the dial gauge from the machine to avoid interference between the dial gauge and

the cam lever.

1. Press the EMERGENCY STOP button to take 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 axis at the 0-degree position.

3. Activate the ST 9 placing solenoid air cylinder (located in the cam box):

Execute the following I/O commands: [Maintenance] - [I/O Check] - [Standard I/O]

- [Y035 ST9 PLACE SOL ENGAGED] - [Output Signal ON]

The cam lever will then follow the cam axis.

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

5. Place a dial gauge on the top end of the cam lever and set the gauge reading to

“0”. In this condition, the cam axis will be at its 180-degree position, and the

nozzle UP/DOWN rod will be at its DOWN limit position. Verify that the nozzle

DOWN limit sensor is ON (X033 ST9 CYLINDER LOWER-LIMIT is ON) at the

I/O screen.

6. While observing the dial gauge, rotate the cam axis in the forward direction to

raise the nozzle UP/DOWN rod. Adjust the sensor’s mounting position so that

the sensor switches OFF (X033 ST9 CYLINDER LOWER-LIMIT switches OFF)

when the rod has been raised 0.3 to 0.4 mm.

7. Adjust the sensor’s mounting position by loosening the sensor lock screw and

sliding the sensor in the front/back directions.

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.
