Replacing the consumable parts

Put a mark at the tensioner

position.

Before loosening the belt tension, put a mark

to indicate the positions of the mounting

bolts of the tensioner (pulley bracket) using

an oil-based permanent marker.

Loosen the belt.

1. Use the hex wrench (3mm) to Loosen the

two mounting bolts of the tensioner

(Pulley bracket) so that the tensioner can

move. It doesn't need to remove the

bolts.

2. Move the belt tensioners (pulley bracket)

to the end of the tension adjusting slots

(in the loosening direction).

Detach the belt.

1. Use the hex wrench (2mm) to loosen the

mounting bolt of the coupling and slide

the coupling to the rear side of the

machine.

2. Detach the belt from the pulley and take

it out through the space between the

pulley and the shaft.

Replacing the consumable parts

Clean the 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.

63729-L3-00

Attach a new belt.

1. Temporarily fit a new belt onto the pulley.

2. Return the coupling to its original position

and tighten the bolt.

3. Move the tensioner (pulley) to the

position that has been marked and then

tighten the bolts.

4. If looseness of the belt is found, adjust

the position of the tensioner (pulley) to

apply necessary tension.

CAUTION

Tighten the mounting bolts of the pulley and pulley

bracket to the following torques:

• Pulley mounting bolt : 5.5N•m.

Be careful not to tighten the bolts excessively.

NOTE

The speciﬁcation of the conveyor belt tension is in the

following. Use the tension meter to adjust as needed.

• Conveyor : 184 to 197Hz

• Extension conveyor : 102 to 109 Hz

Check the belt rotating condition.

1. Cancel emergency stop.

2. Press the [Conveyor Drive Allow] buttons

on the [Unit] - [Conveyor] screen to turn

on the conveyor motor and check the

belt rotation.

3. If the slip of the motor pulley, the belt

rotation fluctuation and the deflection

are excessive, adjust the tensioner

(pulley) position and transfer a board

again and check the condition.

Reattach the conveyor cover.

Tighten the four screws on the plate with

pushing the plate upward to reattach the

conveyor cover.

• Phillips screwdriver

• Oil-based permanent marker

• Brush

• Spatula (Plastic)

• Replacement conveyor belt (refer to "2.2.1 Parts to be replaced during periodic replacement" in chapter 8.)

Change the conveyor width to a

convenient width for maintenance

work.

1. Press the [Width] button to display the

"Conveyor Width" dialog.

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.

Press the emergency stop button

and open the upper door.

The machine must be in emergency stop to

ensure safety during work.

Remove the mask guide plates.

Remove the mask guide plates on the left

and right of the mask clamp. Remove the

mask guide plate on the right. Remove bolts

(4 pcs.) with a hex wrench (3mm) to detach

the mask guide plate. Remove the mask

guide plate on the left with the same

procedure.
