Principle of operation
In tandem operation, two labellers are arranged one
behind the other. Only one of the labellers is in opera-
tion at a time. The other remains in standby.
If the active labeller reports the end of the label roll, it
shuts down. The other labeller takes over the task of la-
belling. The shut-down labeller can now be loaded with
label material.
The LED indicators on the operator panels of the two
machines indicate their respective operating states.
–
ON on the operator panel of the currently active ma-
chine
– LOCK on the operator panel of the machine in
standby
– W__5 , if the respective machine has shut down due
to reaching the end of the label roll
During automatic switch-over from one machine to the
other, the distance between the two machines and their
arrangement are taken into consideration. As a rule,
unlabelled products can be prevented. This guarantees
uninterrupted labelling operation. Reloading periods do
not affect the course of production.
The first machine in the production line is designated as
the master device, the second is designated as the
slave device.
In tandem operation, the dispensing speed is automat-
ically adapted to the speed of the conveyor belt (also
see chapter
Automatic dispensing speed adjustment ).
