Insert label roll in labeler
Further information on adjustment of the labelers is described separately in provided
manual.
Additionally there is a threading pattern sticked on each labeler that shows the guiding of
the label web. Thread the label web accordingly. Please observe that for each labeler and
to the product to be labeled, there will be inserted the correct label roll.
Adjust product light barrier
One light barrier is used for detection of the product at the labeling station. If a product is
detected, a signal is forwarded to the controller of the appropriate labeler to start the la-
beling process.
The point of time of the product detection is significant for the positioning of the label onto
the product. A delay value in the controller enables to change the label position exactly
per each millimeter (s. Alpha manual).
The light barriers are installed at a fix position ex-factory. A position change is not requi-
red. It is even undesired as it may impact the application rate of the labeling station unfa-
vorably.
Depending on product property a balancing of the sensor sensitivity may be necessary.
Particularly glossy and transparent products (e.g. foils) require a careful balancing of the
sensor. Further notes on balancing can be found in the manual of the sensor manufactu-
rer.
