4.4 Inspecting the board conveyor unit
4.4.1 Inspecting and cleaning the conveyor belt
As the conveyor belt wears away, slippages may occur that prevent securely conveying the boards. Periodically
check for wear of the conveyor belt.
Belt wear may also cause trouble such as erroneous detection of the conveyor sensor due to dust from belt
wear accumulating on the sensor surface, or dust from belt wear accumulating in the belt guide grooves may
cause the belt to stick, etc. To avoid such trouble, periodic cleaning of the belt is recommended.
1
Change the conveyor width to a
width allowing maintenance work.
e
1. Press the [Width] button to display the
"Conveyor Width" dialog. Enter a width
large enough for using the maintenance
tools and press [OK].
2. Press the emergency stop button and
then open the cover.
2
Loosen the tension on the conveyor
belt.
1. Using an oil-based marker pen, put a
mark to indicate the current tension
pulley position.
2. Loosen the tensioner bolt with The hex
wrench (4, 5mm) and slide the bolt fully
along the elongate hole (in the direction
of slackening the belt).

3
Detach the belt.
Detach the belt from the pulley and also
from the belt groove on the board guide.
4
Check for wear on the board
conveying side of the belt.
Check for wear on the board conveying
side of the detached belt.

NOTE
If the board conveying side of the belt is worn and the
belt needs to be replaced, replace it with a new one
by referring to the procedure described in the next
section "Replacing the conveyor belt".
5
Clean the pulley and the belt
groove on the board guide.
Using a vacuum cleaner or similar device,
suction up the belt wear dust deposited in
the belt groove or on the sensor surface.
Also clean the pulley and other parts for the
conveyor belt.
