2.1.4 Mode of operation
In labelling mode, the strip is first pulled from the label
roll around the dancer arm [8A], which consistently
maintains even tension in the label strip. The feed roller
[8D] behind the dispensing edge [8C] draws the strip
across the dispensing plate. The label is unfixed from
the backing paper on the dispensing plate and is
pressed onto the product by the pressure roller [8B].
The feed roller drives the label strip forwards the length
of one label and stops until the next product arrives at
the dispensing plate. The strip feed is started by the
product sensor mounted on the conveyor belt. The stop
control provided by the label sensor on the dispensing
edge ensures the feed is halted as soon as a gap is de-
tected between two labels.
The spent backing paper runs from the dispensing
edge around the drive roller [8D] to the rewinder [8E].
The dancer arm regulates the rewinding speed.
The entire operation of the label dispenser is controlled
and monitored electronically. If errors occur, the device
controls output an appropriate notification for the oper-
ator. If necessary, the labelling operating mode is halt-
ed automatically. An electronic signal is output at the
same time. The signal can be fed to an external control-
ler and evaluated.
