Tape Monitoring System
The tape monitoring system alerts the machine attendant when a taping fault occurs, and when it
is time to replace the tape roll. A tape-roll-follower arm is fitted to the machine. A small wheel
mounted on the end of the follower arm makes contact with the tape roll. As tape is applied to the
case, rotation of the small wheel creates a pulsating signal to indicate that tape is fed out. When
the case leaves the tape application zone, the tape roll stops and the pulsating signals stop. The
follower arm also includes a flag that works with a sensor to warn when the tape roll is getting
low.
1.
‘No Tape’ Monitor:
If tape is not applied to the case when the case passes the tape head (e.g., if the tape web
is broken or the tape roll is empty), then pulsating signals will not be present and the
machine will shutdown on a ‘No Tape Applied’ logic test. The Red beacon illuminates until
the machine is
RESET
or
RESTARTED
. Note that the illuminated Red beacon can also
indicate other machine fault conditions.
2.
‘Tape Running’ Monitor:
If tape is not cut at the end of the case, and the discharged case continues to pull tape off
the roll, the pulsating signals continue longer than programmed, and the machine shuts
down on a ‘Tape Running’ logic test. The Red beacon illuminates until the machine is
RESET
. Note that the Red beacon will be also become illuminated if an emergency stop
condition exists or if a guard door is open. It is thus possible to have multiple beacon alarm
conditions at once.
3.
‘Low Tape’ Monitor:
When the tape roll has been depleted to a preset low level, the sensor activates the
flashing Amber beacon, indicating that the tape roll will have to be replaced soon. The
machine logic then measures the tape length dispensed, and stops the machine when the
tape roll has been depleted. The machine can be restarted to use the remaining tape.
