2.1.4 Mode of operation
In labelling mode, the strip is first pulled from the label
roll around the dancer arm [9A], which consistently
maintains even tension in the label strip. The feed roller
[9D] behind the dispensing edge [9C] 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 with the pressure roller [9B].
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 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 detected
between two labels.
The spent backing paper runs from the dispensing
edge around the drive roller [9D], and then over the ten-
sioning plate to be rewound [9E]. The tensioning plate
ensures that rewinding is performed evenly.
The entire operation of the label dispenser is controlled
and monitored electronically. If errors occur, the device
controls output an appropriate notification for the ope-
rator. If necessary, the labelling operating mode is hal-
ted automatically. An electronic signal is output at the
same time. The signal can be fed to an external cont-
roller and evaluated.
