7.1.2 Parts on the TWIN- Head
Fig. 7.1 - 3 Parts TWIN- head
1. CAN Bus Processor board
2. Main board TWIN- head
3. D-axis complete with incremental encoder and force sensor
4. Incremental encoder Z-axis
5. Retract unit to return the Z-axis in a safety area in case of power fail
6. Vacuum generator

Please Note:
Please use this two Positions (7) to move manually the Z-Axis downwards if the Servo board
switch off (Switch off the Axis card)!
Please Note:
The parts 1, 2, 4, 5 and 6 are spare parts and the whole module. ( Service manual).

7.1.2.1 Vacuum generator TWIN- Head
The vacuum generator controls the vacuum, air kiss and the zero balancing position (middle Po-
sition-->no vacuum and no air kiss) for the segments with a aid of a linear motor automatically.

Fig. 7.1 - 5 Principle of the vacuum generator

1. Compressed air input
2. Exhaust air to the silencer and cooling the X-linear motor
3. Output vacuum that go to the D-axis motor through the
shaft of the motor and then to the nozzle.
Filter for the vacuum system on the TWIN- head.
The Filter is mounted on the retract unit and used as an
attenuator to control the vacuum. Together with the defi-
ned length of the silicon pipe reduce the attenuator the
oscillation of the vacuum generator and guaranteed an
accurate vacuum- and air kiss supply.
