2.1 OVERVIEWOFTHE ALS 350
In labelling mode, the drive roller unit [2B] transports
the label ribbon from the unwinding spool [2A]. A loop
is formed in the label ribbon below the pressure roller of
the unwind unit [2C] and the braking brush [2D]. The
feed roller unit [2F] behind the dispenser head [2E]
pulls the ribbon over the dispensing edge. The label
separates from the backing material at the dispensing
edge and is transferred onto the product.
The feed roller unit moves the respective ribbon for a
label and then stops until the next product is transported to the dispensing edge. Label ribbon is co ntinuously
unwound at the unwind unit. The loop acts as a buffer
between the continuously operating unwin d un it an d
the periodically operating label output. The braking
brushes keep the label ribbon taut.
ALS
350
From the dispensing head, the empty backing mate rial
runs over several deflection rollers [2H] and the springloaded, pivoting dancer arm [2G] to the motor-driven
spreader rewinding unit [2I]. The multiple deflections
with the spring-loaded dancer arm act as a buffer between the label output and the rewind unit. When in
operation, the dancer arm pivots back and forth constantly.
The entire operation of the labeller is electronically controlled and monitored. If a malfunction occurs, the control system sends a corresponding message to the
operator. If necessary, the labelling operation is automatically halted. An electronic signal is issued at the
same time. The signal can be picked up and evaluated
by an external control system.

Serial interface
– Almost all of the setting values can be read out and
modified on an external device, the machine status
can be queried, and the machine can be controlled
via this interface.
– For further information, refer to the Service guide
Roll diameter control
– A sensor at the unwind unit monitors the diameter of
the label roll and, along with it, the supply of labels.
– The sensor sends a signal when the diameter of the
label roll reaches a set value.
– This sensor is required if two labellers are operating
in tandem mode (see chapter Operation – Activation and shut-down, page 46)
Adjustable dispensing edge
– The position of the dispenser head can be adjusted
vertically.
– This allows adapting the position of the dispensing
edge to changing products.
– The machine does not have to be moved to adjust
the dispensing edge, the labelling head of the machine does not have to be released.
Spring-loaded dispensing edge
– The dispensing edge is pivotably mounted onto the
dispenser head. A torsion spring in the dispenser
head presses the dispensing edge downward onto
the surface of the product.
– Enables height differences between the products or
surface characteristics difference s to be com pen sated for.
Pneumatic dispensing edge
– The dispensing edge is pivotably mounted onto the
dispenser head. Compressed air presses the dispensing edge downward onto the surface of the
product.
– Enables height differences between the products or
surface characteristics differences to be compensated for.
Printer
– Inkjet or heat transfer printer at the dispenser head.
Applicator
If direct labelling from the dispensing edge is not possible, the labeller can be equipped with an applicator.
Various kinds of applicators are available depending on
the customer’s needs.
Water-resistant electronic control unit
– Protected against splashing water as per type of
protection IP54
– The control electronics, drive electrical system,
electrical fuses and operator panel are built into a
separate switch cabinet
– Driven exclusively by stepper motors
– Motors are protected against splashing water

All of the machine’s functions are electronically
controlled. Using the operator panel, the operators,
calibration technicians, or service personnel have
several options for adapting the machine's functions to
current requirements.
The LED indicator gives the operator feedback messages regarding the current operating state of the machine. Error messages or warning messages appear on
the display as necessary.
Before each operation, the operator must check and
adjust the occasionally changing settings such as the
label position on the product or the dispensing speed.
These settings can simply be input at any time by the
operator at the operator panel.
Task-specific data such as label distance or product
length are programmed at the beginning of a job. As a
rule, the settings are not modified as long as the job is
being processed. This data input require s in- de pt h
knowledge and may only be carried out by trained and
instructed personnel (calibration technicians).
Databanks are available for variable or frequently re curring task settings. The task-specific settings can be
saved in a databank. If the settings are need e d ag a in
after a product change, it is not necessary to re-input
the data. You only need to call up the corresponding
databank. In all, 11 databanks are available.
Only calibration technicians may administer the product
databanks.
It is also possible to modify the basic machine settings.
These are settings such as the motor’s direction of rotation. These settings are not to be changed in norma l
operation. They may only be changed by servicing personnel or the customer service.
To give the operator a better overview, the setting options for occasionally changing settings, task-specific
data, databanks, and basic settings are grouped together in menus: The standard menu, extended menu,
product databanks, and configuration menu. The following table provides an overview of the range of functions of the standard menu, extended menu, and
product databanks. The configuration menu is described in the service guide.
CAUTION!
Erroneous settings can lead to production
setbacks, damage to the machine and system, and can even cause work-related accidents!
– Only specially trained and instructed per-
sonnel may alter the settings in the extended menu or access the product
databanks.

2.5 CONTROLSYSTEM
2.5.2Menus for operators and calibration technicians
During labelling operation, the electronic control system and the sensors monitor the following functions.
Dispensing a label to each product
– A photoelectric sensor (product sensor) sends a sig-
nal when a product reaches the dispensing
edge [12B]. The signal from the product sensor trig-
gers the label feed for a single label.
– If individual labels are missing from the label ribbon,
the label feed compensates for this and advances
the label ribbon by one additional label distance (la-
bel compensation).
– If label compensation does not take place before the
next start signal of the product sensor, the product
does not get labelled. A warning message appears
at the operator panel.
– If the number of unlabelled products exceeds a cer-
tain value, the machine stops.
Label supply
– If no more labels arrive at the label stop
sensor [12A] [13A], the machine stops and sends a
signal to the output to the system controller.
– Roll diameter control (optional) [12D, E]:
If the diameter of the label roll on the unwinding
spool [12C] becomes too small, the control system
sends a warning message and a signal to the output
to the system controller. The diameter at which the
signal will be sent can be set by servicing techni-
cians.

If errors occur
If a malfunction occurs, the control system sends a corresponding message to the operator. If necessary, the
labelling operation is automatically halted. The machine simultaneously sends a signal to the system controller.

Principle of operation
In tandem operation, two labellers are arranged one
behind the other. Only one of the labellers is in operation 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 labelling. 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 ma chine 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 guarantee s
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 automatically adapted to the speed of the conveyor belt (also
see chapter Automatic dispensing speed adjustment).

4.2.2Label stop position(STOD)
After the label is output, the feed continues to operate,
until the next label is present at the dispensing edge. To
ensure that the labels separate completely from th e dispensing edge, it is advisable to allow the feed to run until the next label projects slightly over the dispensing
edge.
The label stop position is the distance between the
leading edge of the next label and the dispensing edge
[54A]. As a rule, this distance should not be more than
3 mm. The respective optimum setting value depends
on the label material used, the product speed, the surface characteristics of the product, and other factors.
£ For problems during the labelling operation, first
check the label stop position.
£ If necessary, set the label stop position as described
below.

Automatic and manual adjustment
The sensitivity of the label stop sensor must be adjusted to match the transparency of the labels and the
backing material. In most applications, it is possible to
allow the sensitivity of the sensor to be adjusted automatically.
When using labels with only a slight difference in the
transparency of the label and the backing material, perforated labels or labels with block outs:
£ Manually adjust the sensors as described below.
Non-standard photoelectric sensors
In series production, the labeller is equipped with a
photoelectric sensor manufactured by Wenglor.
When using transparent labels or labels with a very
slight difference in the transparency of the label and th e
backing material:
– It is possible that the gap between two labels will not
be detected. Instead of just one label, two or more
labels might be dispensed.
– Use of a mechanical or capacitive sensor is recom-
mended.
– A mechanical sensor is only of limited use at high
dispensing speeds.

Example [81]:
If the product [D] reaches the product sensor [C], a start
signal is sent and the machine dispenses a label. The
recesses in the product trigger additional start signal s;
without the PRDL function, the product would be labelled several times. With the product length [A] set in

[86] A RPM transmitter (speed sensor) on the conveyor line
The automatic dispensing speed (APSF) makes it possible to automatically adapt the dispensing speed to the
speed of the conveyor belt. The speed of the conveyor
belt is picked up by a speed sensor [86A] and transmitted to the control system of the labeller. The control
system calculates the permanent position and speed of
the products. The resulting values are used for contro lling label feed, unwinding, and rewinding and are constantly monitored and regulated. Fluctuations in the
conveyor belt speed are automatically compensated
for. If the conveyor belt stops, the label dispenser also
stops.
The conveyor belt can stop even while a label is being
dispensed. The label feed is then stopped as well. Only
when the belt starts running again, does the label feed
move the label to the next gap on the label ribbon.
Conveyor belt and label dispenser are operating in perfect synchronisation. As a prerequisite for this, the RPM
transmitter must be correctly adjusted. Depending on
the operating conditions, the relationship between the
dispensing speed and the conveyor belt speed must be
finely adjusted (EGRA function).
Only servicing technicians are permitted to configure the label dispenser for APSF mode. For
further information, refer to the service guide.

a high conveyor belt speed, the allowable
dispensing speed can be exceeded.
– If the dispensing speed is too great, the
warning message W__4 appears.

4.6.1Principle of operation
If direct labelling from the dispensing edge is not possible, the labeller can be equipped with an applicator. In
applicator mode, the applicator takes the label from the
dispensing edge and carries it to the product.
The labeller can be equipped with various applicators,
depending on the need. The following are possible:
– Air Stream Applicator (pneumatic applicator):
Using suction, the applicator takes the label from the
dispensing edge, transports it until it is directly in
front of the product and then blows the label onto it.
– Electro-pneumatic Applicator (EP applicator):The
applicator uses suction to take the label from the
dispensing edge. Then a pneumatic cylinder ex-
tends and presses the label onto the product.
– Electro-pneumatic Applicator (EP applicator):The
applicator uses suction to take the label from the
dispensing edge. Then a pneumatic cylinder with
the label traverses into the application position a nd
waits there for the product. When the product reach-
es the pneumatic cylinder, it presses the label onto
the product.
