Trumpf BendMaster 150, Руководство оператора

Страница: 73 / 258

The precise position of the workpiece is determined (±0.2 mm) in
order to position the gripper properly. To avoid daylight influen-
ces, narrowband flash lighting (green LED flash) is used for the
fine recognition process.
This process can be carried out twice at different points of long
components to avoid angle errors.
The workpiece can be picked up after it has been positioned
precisely. If
Backlighting table "load mode" was selected, fine
recognition is carried out on the separately installed backlighting
table without a diode flash.
3.6 Rotational transformer
A continuous rotational transformer is integrated in the D axis,
which allows the D axis to be rotated without an end position.
The rotational transformer transfers compressed air, vacuum, AS-
i bus signals and 24 V DC for the vacuum gripper.
It is driven by an attached servomotor.
3.7 Safety fencing
The safety fencing prevents access of persons in automatic and
manual press mode and also prevents workpieces from falling
out of the machine.
Monitored sliding doors allow controlled access in order to load,
unload and refit the machine.
3.8 Control panel
There is a control panel outside the safety fencing. A portable
manual control unit with 8.4" screen is also there. A stationary
19" screen can be optionally connected.
The control panel can be integrated in a corporate network
which can be used for offline programming.
The control panel is connected to the traveling control unit in the
switch cabinet of the BendMaster and to the control of the press
brake via a local network.
