4.1 Replacing the conveyor belt
If significant looseness, contamination, or scuffing is found in the conveyor belt when performing the work
steps in "5.2.1 Inspecting conveyor belt and cleaning guides and pulleys" of Chapter 3, the conveyor belt
needs to be replaced.
1
Change the conveyor width to a
convenient width for maintenance
work.
1. Press the [Width] button to display the
"Conveyor Width" screen.
2. In the "Target Width" box, enter a width
large enough for maintenance work
(about 200mm) and press the [OK]
button. The conveyor is changed to the
specified width.

Loosen the belt.
1. Before loosening the conveyor belt, mark at the current position of pulley with a permanent marker.
2. Loosen the pulley mounting screws applying the tension with a hex wrenches (5 and 4) referring to
the figure below.
3. Move the pulley to the direction that the belt is loosened.

Separate the spline shaft from the
drive pulley.
Remove the mounting bolt from the belt
drive pulley with a hex wrench (3). (See the
figure shown in Step 4 for the pulley
position.) Pull out the spline shaft to make a
clearance.

Clean the belt 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.

CAUTION
Do not use a solvent (absolute ethanol, 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.

Replace the conveyor belt.
1. Reattach a new belt temporarily while
putting it on the pulley.
2. Loosen the mounting bolt and connect
the spline shaft.
3. Move the pulley applying tension to the
position marked in Step 4 and install the
mounting bolt.
4.
If looseness of the belt is found, adjust the
pulley position to apply tension.

NOTE
The conveyor belt tension standard value of this
machine is 520 to 580 Hz. Adjust the conveyor belt
tension with a tension meter as necessary. The same
standard value applies to the extension conveyor type.
c
CAUTION
The tightening torques of the pulley mounting bolt that
applies tension is 5.5N·m. Do not tighten the bolt
excessively.
