2.1 OVERVIEW
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 detected 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 operator. If necessary, the labelling operating mode is halted automatically. An electronic signal is output at the same time. The signal can be fed to an external controller and evaluated.
