2.1.4 Mode of operation
In labelling mode, the label web is first pulled from the
label roll around the dancer arm [5A], which consistent-
ly maintains even tension in the label web. The feed
rollers [5D] in front of and behind the dispensing
edge [5C] draw the label web across the dispensing
plate. The label is peeled from the backing paper on the
dispensing plate and is pressed onto the product by the
pressure roller [5B].
The feed roller drives the label web 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 [5D] to the rewinder [5E].
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.
[5] The ALS30x Label Dispenser is ready for operation in its
