3.5 Safety Functions
Faults in the current supply:
Owing to its specific control concept the COBRA 501 is
immediately separated from the chain or roller conveyor in
the case of such a fault and remains in the safe resting
position until the fault has been remedied. After this, the
COBRA is started again.
Swing-out mechanism of the pick-up arm:
The swing-out mechanism stops major damages, e.g.
- in cases where the pick-up arm (fig. 6, item 6) is still
engaged whereas the carriage (fig. 2, item F) already
bangs against the stop at the frame,
- in cases where the chain speed is too high and/or the
system control is too low or when the SN position switch
fails to operate.
Description of the swing-out mechanism:
The roller side bar (6) is attached to a hinge (4). In case of a
troublefree operation, the hinge (6) forms a 90° angle
a
to the
lubrication head center line. In this position, the hinge is
maintained by a spring washer kit (5).
In the above mentioned malfunction, the hinge overcomes
the tension force of the spring washer kit and swings out of
the engaging area of the chain via the screw (3) as the spin
axis.
Setting of the swing-out mechanism:
After remedying the fault:
1. Loosen nuts (7) and swing the pick-up arm into a 90°
position to the lubrication head center line. Overcome the
retention force of the ball thrust pieces (2) by light beats
with
a plastic hammer (the ball thrust pieces serve as a fixing aid
for setting the 90° angle).
2. Tighten nut (7) with 34 Nm and fix by a lock nut.
Pick-up arm and lubrication head
move back into the initial position
automatically.
Warning: Danger of bruise in case of
an interruption of the power supply.
