Maintenance

5.3 Inspecting and cleaning the conveyor belt

Inspect the conveyor belt for wear. As the belt wears away, slippages may occur that prevent securely

conveying the boards. It is therefore necessary to make periodic checks for wear of the conveyor belt.

Belt wear may also cause trouble such as erroneous detection of the board 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.

Required tools

• Hex wrenches 4mm, 5mm

• Vacuum ASSY (option)

Change the conveyor width to a

convenient width for maintenance

work.

1. Open the [Unit]-[Conveyor] tab and

press the [Width] button to display the

"Conveyor" dialog box.

2. In the "Target Width" box, enter a width

large enough for maintenance work

(about 200mm) and press [OK].

The conveyor is changed to the width

that was just entered.

2. Open the [Unit]-[Conveyor] tab and

press the [Stopper] button to raise the

board stopper.

Open the front safety door of the

machine.

Loosen the tension on the conveyor

belt.

1. Place a square piece of cloth over the

guide and ball screw.

2. Use the hex wrenches (4 mm and 5mm)

to loosen the belt tension (tension pulley)

of the conveyor.

53428-M6-00

Remove the conveyor belt.

1. Use the hex wrenches (4 mm and 5mm)

to loosen the pulleys at both ends.

2. Remove the conveyor belt from the

pulley and the belt groove of the board

guide.

TIP

The belt can be removed when the pulleys at both

ends are loosened, so you do not have to loosen the

other pulleys.

Check for wear on the board

conveying side of the belt.

After removing the belt, check for wear on

the board conveying side of the belt.
