Bulk Case System and Nozzle Changer
5.3.10 Bulk Case System and Nozzle Changer
Another adjustable regulator is used to reduce the 5.0 bar to 2.5 +0.5 bar. This air supply is used for the
bulk case and for the nozzle changer at the C&P 6/12 head.
Compressed A ir Supply to the C&P20A
5.3.11 Compressed Air Supply to the C&P20A
The 4.8 bar air supply to the C&P20A is needed for the following functions:
▪ Vacuum supply in the holding circuit
▪ Vacuum and air blast supply for the placement circuit (pressure control valve)
▪ Cooling facility for the X axis motor.

Another use of the 4.8 bar compressed air is for the Z axis
safety mode. As long as the machine is in normal mode,
the Z axis can move freely within its travel range. In the
case of power cuts or when the machine is switched off,
a safety mode is needed since the weight of the Z axis
causes it to fall down and it could be damaged when the
gantry is moved. With the help of the retract unit, the Z
axis can be moved to a safe position in just a few ms. In
the event of a fault, like a power cut, the power fail mode
is also activated, which powers the Z axis for about 200
ms seconds with the aid of a capacitor, located in the
main power supply. This ensures that the Z axis moves
up with the power provided and with additional help from
the return spring.

Cooling the X Axis Motors
5.3.14 Cooling the X Axis Motors
Cooling the Y Axis Motors fo r Placement Are a 1/2
5.3.15 Cooling the Y Axis Motors for Placement Area 1/2
To cool the Y axis motors, an additional pneumatic system is integrated, which sucks the air from the
environment, compresses it in a compressor and conducts its through a hose system to each of the Y
axis motors.
The motor coil temperature is monitored. If this exceeds 110°C, a message will appear on your screen.
This simple cooling system is installed to ensure that the Y axis does not overheat.
Cooling system X axis motor
The exhaust air from the vacuum generator (pressure
control valve) of the C&P head is used to cool the X axis
motors.
