Machine loading:

• All stored items must be unloaded in advance.

Machine operating

condition:

• Shut down

Main electrical

power:

• Equipment disconnected from power supply system. The Main Switch

(switched off) locked by means of a padlock to secure the main switch

against unintentional switching on.

Compressed air /

Nitrogen (if used):

• Equipment disconnected from compressed air or nitrogen supply.

Access:

• Open both doors of the machine.

• Pull the Z axis towards you.

• Pull the gripper up (is a bit hard because the Z motor has a break) so

you have better access.

6.2.4 Exchange steps

Step 1

Note:

To prevent the Y axis from falling down,

securely hold it during removal of the

screws. It is recommended to move the Y

axis completely to the bottom before

loosening and removing the screws to

prevent it from falling down.

Remove the 8 screws that connect the whole Y

axis to the Z belt.

Lay the whole Y axis carefully down (if not

already done).

Step 2

Pull the

Z belt until the screw of the coupling is

visible.

Loosen the screw of the coupling. Now, the Z

belt should be easily movable by hand and the

coupling should not turn with this movement.

Step 3

Remove the belt tensioner screw. During

loosening hold the lower part in your hand to

prevent it from falling down on the Y axis.

Loosen the four screws on both belt holdings as

far as the belt can be pulled out.

Now it is possible to remove the whole belt by

pulling on t

he upper end.

Step 4

Remove the deflection pulley by removing the

four screws at the back of the Z axis.

Step 5

Check the length of the new belt which must be

4453 mm ± 2 mm

Push the belt over the upper pulley and down

inside the back of the Z axis until it does not go

furthe

Step 6

For the next step it is required to have access to

the bottom pulley. Therefore, the whole Y axis

must be lifted and secured. Put a piece of wood

or steel below the axis to hold it securely into

place. Do not put force on the gripper itself.

Instead, secur

e the spacer below the Y axis.

Another possibility is to fasten a clamping set

around the Z axis. Be careful not to damage or

scratch the linear bearings.

Note:

The spacer has to be securely placed as

work will be done right below the Y axis.

If the Y ax

is falls down it could cause

injury and damage to the machine. In

case of doubt, only lift the axis for a short

distance.
