BEAD BREAKING
When this Subprogram is running, the data required for
the successive work cycles is acquired automatically
by the sensors fitted on the Bead Breaker Arms and
using a Laser detector. The data acquired includes the
positions of the upper and lower rim edge, which are
indispensable for performing the required operations.
During upper or lower bead breaking operations, you
can release the lever (2, Fig.4.1-2) and continue the
rotation procedure using the pedal (3, Fig.4.1-3). The
bead breaking disk is not allowed to move so the operator
can lubricate the entire circumference freely to increase
the efficiency of the operation.
In the same way the rotation pedal can be released at
any time and bead breaking can be resumed using the
lever (2, Fig.4.1-2).
When the machine is performing the lower bead breaking
operation it also acquires the rim width data.
The Bead breaking Subprogram is completed by a laser
scan of the upper rim flange.
REMOVING THE UPPER BEAD
Having completed the bead breaking operations, keep
the lever (2, Fig.4.1-2) activated to move the bead
breaking disks into the idle position. The Upper Bead
Removal operation continues automatically with the
upper tool being moved up until it grips onto the upper
bead.
If the bead slips back into its housing on the rim it
should be pressed back into the groove using the bead
pusher.
This phase is completed by a temporary stop (signalled
by a beep) in which the operator is requested to inspect
that everything is correct before proceeding.
WARNING:
IF THE BEAD IS POSITIONED CORRECTLY IN THE
RIM DEAD CENTER, WORK CAN PROCEED.
The Subprogram continues by extracting the upper bead
and finishes when the tools are positioned correctly for
extracting the lower bead.
The operation is now finished and the automated cycle
can proceed directly to the next Subprogram.
