Differences in conveyor belt replacement depending on the machine stage type
Regarding W2 and W3 conveyor belts for YSM20R Dual-stage type, belt replacement procedure is different from other
conveyor belts. Go on to Step 10 for replacement procedures other than W2/W3 conveyor belts for YSM20R Dual-stage type.

Replacing the conveyor belt (YSM20R Dual-stage W2/W3)
5
Read desired board data.
1. Read desired board data.
2. If the value on "B. Board Size Y (mm) on
"Board" screen is 380 mm or more, enter
the value less than 380 mm.
6
Move the conveyor U-axis.
1. Close the machine safety cover and
cancel the emergency stop. Set the
carriage if the machine is the carriage
type.
2. Press the [Mount Position] button on the
[Setup] screen to move the conveyor to
the component mounting position.
e
3. Press the emergency stop button and
then open the machine safety cover.
4. Detach the carriage if the machine is the
carriage type.
5. Moving the U-axis belt manually moves
the entire conveyor. For the W2-axis, fully
move the conveyor to the rear side by
moving the U-axis belt in the direction
indicated by an arrow shown in the
figure on the right. For the W3-axis, fully
move the conveyor to the front in the
same manner.
TIP
The stage 2 (W2-axis) and stage 3 (W3-axis) move back
and forth by pressing [Mount Position] button when
"Board Size Y" is less than 380 mm.
7
Separate the shaft.
Remove the bolt from the shaft (for the
pulley position, see the figure shown in Step
4) with a hex wrench (3).
8
Pull out the shaft from the belt
drive pulley.
Pull the shaft toward the front for the W2-axis
or the rear for the W3-axis to pull it out from
the drive pulley completely.
n
NOTE
When pulling out shaft, drive pulley comes off easily.
Therefore, pull out the shaft holding pulley with hand.

Separate the shaft from the drive
pulley.
Remove the bolt from the belt drive pulley
(for the pulley position, see the figure shown
in Step 4) with a hex wrench (3), and then
pull out the shaft to make a clearance.

Clean the belt guides and pulleys.
1. Use a vacuum assembly (option) to suck
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.
c
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 ethanol, be careful
not to spill the ethanol on the bearing in the pulleys
during cleaning.
e
Replace the conveyor belt.
1. Reattach a new belt temporarily while
putting it on the pulley.
2. (YSM20R Dual-stage: W2, W3) Pass the
drive pulley through the shaft.
3. Loosen the mounting bolt and connect
the shaft.
4. Move the bracket (YSM20R/YSM20WR
Single-lane/YSM20WR Dual-lane: pulley)
to the position marked in Step 4 and
install the mounting bolts.
5.
If looseness of the belt is found, adjust the
bracket (pulley) position to apply tension.
c
CAUTION
The followings are tightening torques of the tensioner
mounting bolts. Do not tighten the bolt excessively.
Pulley bracket mounting bolt : 3.8 N•m.
Pulley mounting bolt : 5.5 N•m.
