Dual stage specification : Replacing the conveyor belt of W2-axis
The following describes conveyor belt replacement of the dual-stage W2-axis. First perform Step 1 through 4 in the
preceding section "
n

Read the board data.
1. Read the board data of your choice.
2. Open the [Board] – [Board] screen, and
change the “A: Board size X (mm)” to
“330” or less, and “B: Board size Y (mm)
to approx. “200”.
TIP
By reading the board data, the [Mount Position] button
used in the next Step becomes active.

Move the conveyor to the mount
position.
1. Close the machine’s safety cover, and
cancel the emergency stop. If the
machine could be equipped with a

Loosen the belt.
1. Press the emergency stop button, and
open the machine’s safety cover. If the
machine is equipped with a carriage,
remove the carriage.
2. Loosen the fixing bolt of the pulley that
tension is applied using two hex
wrenches.
Pulley side: Hex wrench 5 mm
Fixing bolt side: Hex wrench 4 mm
3. Move the pulley all the way to the end of
the slot (in the loosening direction).

Remove the bolt securing the shaft.
1. Open the safety cover at the rear of the
machine.
2. When moving the W axis belt of the W2
far side conveyor rail to the right of the
person facing, the conveyor rail moves
to the front side of the machine. Push the
conveyor rail forward about 100 mm,
and the bolt securing the spline shaft
can be accessed.
3. Remove the bolt securing the shaft with
the hex wrench (3). Turn the hex spline
shaft to face the bolt to your side, it
becomes easy to access.
4. Turn the W axis belt to the opposite
direction from 2, and move the far side
conveyor rail all the way to the end of
machine.

Clean the guides and pulleys.
1. Use a vacuum assembly (option) to
suction the belt wear debris on the belt
guides and sensors, etc.
2. Use a plastic spatula or similar tool to
remove the belt wear debris adhering to
the outer peripheral surface of the
pulleys.
3. Use a brush or similar tool to remove the
belt wear debris caught in the belt
guides.

CAUTION
Use a plastic spatula and brush to avoid scratching the
pulleys and guides.
c
CAUTION
Do not use a solvent (IPA, etc.) unless the guides and
pulleys are excessively dirty. If using a solvent, be
careful not to spill the solvent on the bearing in the
pulleys during cleaning.

Attach the conveyor belt.
1. Temporarily attach the new conveyor
belt by hooking to the pulley.
2. Insert the shaft through the driving pulley.
3. Tighten to secure the spline shaft with the
fixing bolt.
4. Move the pulley that tension is applied
to the position marked in Step 4, and
tighten the fixing bolt.
5. When the belt is loose, adjust the position
of the pulley to apply belt tension.
n
NOTE
For the tension measurement position and tension
standard of the machine’s conveyor belt, see the figure
in Step 9 of "
n
Dual stage specification : Replacing the
conveyor belt other than that of W2-axis".
c
CAUTION
The tightening standard of the securing bolt of pulley
that tension is applied is 5.5N·m. Be cautious not to
tighten too hard.
e
Attach the board clamp plate.
1. Fit the board clamp plate into its original
position and tighten the board clamp
plate mounting bolts with a hex wrench
(3).
2. Remove the square cloth on the push-up
plate.
