Pretensioning
Before the suction process starts, the reservoir integrated into the
suction bar must be evacuated.
The amount of time this process takes varies based on the suction bar
type and the length. Generally, this process is started approximately
three to five seconds before picking up the load.
Activating magnetic valve I (separating cylinder):
The cylinder’s piston rod extends and separates the suction
chamber from the storage chamber. Vacuum is generated in the
storage chamber.
Activating magnetic valve II (ventilation cylinder):
The cylinder’s piston rod extends and seals the ventilation shaft.
Picking up
Once the sealing mat has been placed on the workpiece, the system
can start picking it up.
Resetting magnetic valve I (separating cylinder):
The cylinder’s piston rod is retracted and the load is picked up.
Depositing
Once the workpiece has been transported and set down, it must be
deposited.
Resetting magnetic valve II (ventilation cylinder)
The cylinder’s piston rod is retracted, the vacuum in the suction
chamber drops and the workpiece is released from the sealing
mat.
Caution:
Operating the vacuum blower with the reservoir sealed can cause
the vacuum blower to overheat after 2 minutes of continuous
operation.
The cylinders are retracted when no voltage is applied. This means
that the storage and suction chambers are connected to each other
and the ventilation shaft is open.
This open circuit ensures that the vacuum blower is cooled sufficiently.
