4.1 Replacing the conveyor belt
The conveyor belt should be replaced if excessive slack, grime or fraying is found after checking it as
described in Chapter 3, "5.2 Inspecting conveyor belt and cleaning guide".
Use the following procedure to replace the belt. Moreover, as the replacement procedure varies for CV1, 2,
4, and CV3 by Step 5 and later, they are described separately.

Change the conveyor width to
convenient for maintenance work.
1. Press the [Conveyor width] button on the
[Unit] - [Conveyor] scree and open the
conveyor width changing screen.
2. Input the value (approx. 200mm) which a
hexagon wrench can be inserted into the
"Changed conveyor width" and press the
[OK] button. Then the conveyor width is
changed to specified width.
2
Prepare for work.
e
1. Remove all items sensitive to magnetic fields
such as wristwatches and magnetic ID cards.
2. Press the emergency stop button and detach
the feeder exchange carriage.
3. Open the machine safety cover and detach
the upper cover.
4. Place a square cloth on the push-up plate.

Loosen the conveyor belt.
1. Mark the current position of pulley bracket (CV2 and CV3) and pulley mounting bolt (CV1 and CV4) using a
permanent marker before loosening the conveyor belt.
2. Loosen the mounting bolt of pulley bracket (hereinafter referred to as bracket) using a hexagon wrench (3),
referring the figure below, then move the bracket to the end of its long hole (loosening direction).
For CV1 and CV4, loosen the mounting bolts of pulley using a hexagon wrench (5) and (4), then move the
pulley.

Replacing the CV3 conveyor belt
The replacement procedure of CV3 conveyor belt differs to other conveyor belts. Here describes the
procedure from Step 5 and later. When the conveyor belt other than CV3 is to be replaced, see
"Replacing the CV1/CV2/CV4 conveyor belt" described below.
5
Move the conveyor U-axis.
Whole the CV3 conveyor can be moved by
running the U-axis belt manually. Run the U-axis
belt to the arrow direction shown at right to
move the CV3 conveyor to frontmost.
6
Detach the shaft by removing the shaft
mounting bolt (see the figure of Step 4
for its position) using a hexagon wrench
(3).
7
Pull out the shaft from the belt drive
pulley until they are completely pulled
out.
n
NOTE
The belt drive pulley may come off upon pulling out the
shaft, so that hold the pulley by hand while pulling out the
shaft.
