7.1.10 Mechanical Valve Switching (ST9)

Point

The nozzle vacuum switches from ON to OFF with the movement of the mechanical

valve at station 9. The vacuum cut is timed to allow part placement. Ensure that the

part is placed correctly on the production panel.

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.

2 Ensure that distance A (see figure below) is 8.9 mm for all heads. Use a special

jig (Z9827DGPJ029*) to check this distance.

WARNING

• Press EMERGENCY STOP before performing this procedure.

• Exercise extreme caution when working on the machine if the cam

is not at its origin (0 deg.). Spring recoil can rotate the cam inde-

pendently.

Valve Switching Lever Height Adjustment

This adjustment should be performed on the low valve shaft after completing adjust-

ments to the vertical movement of the nozzle. (Refer to 7.1.9 “Nozzle Vertical Move-

ment During Placement” for details.) The low valve shaft can be identified by

measuring the lower surface of the mechanical valve spool on all shafts. Raise the

spools and measure with a dial gauge, as shown in the diagram below.

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

2 Remove the mechanical valve block from the shaft that will be used for adjust-

ment.

Caution: There are two O-rings on the mechanical valve. Be careful to not drop these during removal

of the mechanical valve. Also, do not disassemble the mechanical valve if not necessary.

3 Position the centering jig (Z9827DGPJ032*) on the shaft in the mechanical valve position.

Lift the jig against the top ridge and push it to the right against the vacuum hose manifold

(black plastic).

WARNING

• Press EMERGENCY STOP before performing this procedure.

• Exercise extreme caution when working on the machine if the cam

is not at its origin (0 deg.). Spring recoil can rotate the cam inde-

pendently.

4 Tighten the mounting bolts with a torque of 0.8 N.m (8Kgf.cm).

5 Set the cam angle to 0°, then activate the place solenoid (Y035 ST9 PLACE SOL

ENGAGED) at station 9 to work the lever.

6 Use the cam handle to rotate the cam to 190°. The pusher on the lever should align

smoothly with the centering jig.
