Applicator Operation
Function
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.
Those applicators are all driven by compressed air. The following are possible:
LTP / LTPV LTP (Light Touch Pneumatic) and
LTPV (Light Touch Pneumatic Vacuum):
Applicator with „Light Touch“ function. „Light Touch“ means, that the move-
ment of the (compressed air) cylinder is limited by sensors, which react to a
light touch onto the product. The LTPV additionally sucks the labels on with a
vacuum nozzle.
Advantages:
•
Application on products with different heights possible
•
Only light pressure onto the product (important with sensitive products)
PEP IV
The cylinder movement is limited by a setable length of time. After the run out
of this application time, the applicator moves back into home position.
PEP Blow on
PEP-type applicator with blow on function: After run out of the application time,
the blow on function is activated. After run out of the blow on time, the appli-
cator moves back into home position.
PEP II Sensor The cylinder movement is limited by a (touch down) sensor, which signals the
contact to the product and triggers the backwards-movement.
ASA ASA (Air Stream Applicator)
This applicator type has no moving parts, but blows the label onto the product
(also called „blow box“). After the start signal, the blow on valve is opened for
a setable time length.
Reverse PEP This applicator is partly time related. Working procedure:
The applicator moves to its end position and “waits“ for the start signal. The
start signal triggers the blow on valve which is active for the defined blow on
time. After the run out or the blown on time, the applicator moves to home po-
sition, gets the next label and moves to the wait position.
BTS
BTS (Bad Tag Separator)
This device does the opposite of an applicator: it removes labels from the dis-
pensing edge of a labeller. The BTS is used for sorting out RFID labels, which
could not be read/written properly.
LA-BO
The LA-BO (Label Applicator Blow On) is a blow-on applicator. It works like the
ASA does (see above).
