5-8. Replacing the T-PIN Sensor (Optional)

1) Remove the adjustment screw to detach the sensor bracket and replace the sensor.

When reassembling the components, adjust the position of the sensor bracket by loosening the

adjustment screw and moving the sensor bracket up and down so that the T-PIN sensor is

turned ON when the center ring pin is lowered by 1.5

-0.5

mm.

2) Carefully handle the cables.

5-9. Replacing the Pusher Y Cylinder (Outer Shape Reference)

1) Remove the parts c to detach the cylinder. As the cylinder is detached,

the spring is also then removed.

2) Detach the speed controller from the cylinder. (At this time, check what

side the speed controller has been mounted.)

3) With the cylinder rod secured with a spanner, remove the part d with

another spanner.

4) Reassemble the components in the order of steps 3) to 1).

5) After the cylinder components have been assembled, supply the air

(0.49 MPa) to check that the cylinder moves smoothly.

∗ The cylinder mounting direction of the front reference machine is different from that of the rear

reference machine.

∗ For the rear reference machine, secure the speed controller with a tie-up band so that it does not

interfere with the width adjustment timing belt when the PWB width is set at its maximum level.

∗ The speed controller of the cylinder has been adjusted (page 5-9 in QA Table). No adjustment is

needed even after replacement of the parts.

5-10. Replacing the Centering Pin (Optional)

1) Loosen the screws c, d and e of the guide block A and guide block B to detach the centering

pin together with the guide blocks.

2) At this time, also detach the T-PIN sensor (together with its bracket) from the reference side.

Removing the E ring

allows you to pull the centering pin

from the damper block.

Removing the E rings

(two in total, top and bottom) allows you to remove the centering pin

When installing a new centering pin, reassemble the components in the reverse order. The

E-rings must also be replaced with new ones.

After the components have been reassembled, adjust the sensor position in the same manner

as described in 5-10, Replacing the T-PIN Sensor.
