1.2.2 Operational safety of the unit
Proper usage
The label dispenser described here is designed for
dispensing and applying pre-printed self-adhesive
labels to products or packages.
The label material that is used must be punched and in
roll shape. Punched means that the labels adhere
individually, separated by punchings, on a carrier
material. The labels must only adhere strongly enough
so that they will come loose when the material is
deflected over a sharp edge.
Usually, the label dispenser is integrated into a
superordinate system, e.g. a packaging system, by a
system integrator. The labels are typically attached to
products, which are moved by by an automatic
conveyor.
Any other type of or more extensive application will be
considered non-intended use.Avery Dennison shall
assume no liability for damage resulting from non-
intended use of the machine.
The system integrator must install the machine with
suitable equipment to protect operating personnel from
danger; for example, the danger of the hands or fingers
being crushed by reaching in between the product and
the dispensing edge.
WARNING!
Improper usage of the unit can cause
accidents, property damage and production
downtime!
Only use the unit in accordance with the
instructions specified in this manual.
Do not operate the unit without the
required safeguards.
Only configure the unit in accordance
with this manual and with the required
care.
Only use original accessories.
Do not make any modifications or
alterations to the unit.

2.1.4 Mode of operation
In labelling mode, the strip is first pulled from the label
roll around the dancer arm [10A], which consistently
maintains even tension in the label strip. The feed roller
[10D] behind the dispensing edge [10C] 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 [10B].
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 [10D] to the rewinder [10E].
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.
[10] The ALS 20x Label Dispenser is ready for operation in its
idle mode.
