Periodic maintenance items

Remove the belt from the pulley.

Check that the removed belt is not cracked,

worn and frayed.

If the belt is cracked or worn, replace it

referring to "2.1 Replacing the conveyor

belt" in Chapter 6.

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.

53394-N9-00

CAUTION

Use a plastic spatula and brush to avoid scratching the

pulleys and guides.

CAUTION

Do not use a solvent (IPA, 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.

Reattach the belt.

1. Temporarily place the belt on the belt

tensioner pulley.

2. Place the belt on the end pulley

removed in Step 4 and mount it with the

pulley shaft together with the washer.

3. Move the belt tensioner pulley to the

position marked in Step 4 and tighten the

bolt while applying tension.

4. If there is a slack in the belt, adjust the

position of the belt tensioner pulley to

apply proper tension.

53374-N9-00

NOTE

The speciﬁed conveyor belt tension for this machine is as follows. Use a tension gauge to adjust the belt tension as

needed. Stage 1 : 260 to 320Hz / Stage 2 : 180 to 220Hz

CAUTION

The tightening torque for the belt tensioner pulley is 5.5 N·m. Be careful not to overtighten.

Attach board clamp assembly.

1. Attach board clamp assembly to the original position. Mount it by tightening 4 bolts with hex wrench

(2.5).

2. Remove square cloth.

Return the tape cutter duct to the original position.

5.3.2 Cleaning and greasing the hexagon spline

The cleaning and lubrication procedures for the conveyor's IN and OUT port hexagon splines are given below.

See "Chapter 5 Lubricating points" for lubricating points and lubricating type.

Set the conveyor width to the

maximum.

Manually set the conveyor width to the

maximum.

Prepare for work.

1. Remove all items sensitive to magnetic

fields such as wristwatches and magnetic

ID cards.

2. Press the emergency stop button to put

the machine in emergency stop.

3. Use the CLAMP ON/OFF switch to lower

the feeder exchange carriage and

detach it.

Clean the hexagon spline.

Wipe away old grease and dirt from the

entire hexagon spline with a lint-free cloth

(for clean room).

53376-N9-00

NOTE

If it is difﬁcult to clean the hexagon spline due to the

tape cutter duct, then remove the tape cutter duct.

Note, however, that emergency stop cannot be

canceled when the tape cutter duct is removed. So

you will have to reattach it to cancel emergency stop.

Wipe the rest of the hexagon spline.

1. Set the feeder exchange carriage and

cancel emergency stop.

2. Narrow the conveyor width manually,

press the emergency stop button again,

and detach the feeder exchange

carriage.

3. Wipe the rest of the hexagon spline that

could not be wiped.

Apply grease.

Apply a uniform coat of the specified grease

(NSL) by hand over the surface of the

hexagon spline. As with Steps 3 to 4, adjust

the conveyor width to apply grease over the

entire hexagon spline.

5.3.3 Cleaning/lubricating W-axis ball screw and guides

This section describes the procedure for cleaning and lubricating the conveyor W-axis ball screw and guides.

See "Chapter 5 Lubricating points" for lubricating points and lubricating type.

Set the conveyor width of Lane 1 to

the maximum.

Press the [Unit]-[Conveyor]-[Width] button

and set the conveyor width of Line 1 to the

maximum.

Lower the push-up plates of Lane 1.

Make sure that the push-up plates are

lowered. If not lowered, press the [Unit]-

[Conveyor]-[Push Up] button to lower the

push-up plates (2 plates for stages 1 and 2)

of Lane 1.

Prepare for work.

1. Remove all items sensitive to magnetic

fields such as wristwatches and magnetic

ID cards.

2. Press the emergency stop button to put

the machine in emergency stop.

3. Use the CLAMP ON/OFF switch to lower

the feeder exchange carriage and

detach it.

Detach the push-up plate.

Use a hex wrench (4) to remove the bolts (4

places per stage) that detach the push-up

plates, and then remove the push-up plates.

53378-N9-00

NOTE

If it is difﬁcult to clean the ball screw and guide due to

the tape cutter duct, then remove the tape cutter

duct. Note, however, that emergency stop cannot be

canceled when the tape cutter duct is removed. So

you will have to reattach it to cancel emergency stop.

WARNING

THE PUSH-PLATE IS A HEAVY ITEM, AND IT MUST THEREFORE

BE HANDLED WITH CARE TO AVOID INJURY.

Clean the ball screw.

Wipe away old grease and dirt from the

entire ball screw with a lint-free cloth.

53379-N9-00

CAUTION

Carefully wipe the lead grooves of the ball screw during

cleaning. After cleaning, make sure that no dust, lint

and debris remain on the ball screw.

Clean the guide.

Wipe away old grease and dirt from the

entire guide with a lint-free cloth.
