7.3 Label Applicator
Switch on the label printer and the display shows the main menu.
Press the key to access the function menu.
Press the key until the menu Label applicator is displayed.
Press the key to select the menu.
Press the key to change to the next mode.
Stamp on:
The label remains in a fixed position. The label is pressed directly onto
the product.
Blow on:
The pad moves to a pre-adjusted position approximately 10 mm away
from the product. The label is blown onto the product by an air jet
stream. The print and apply cycle performs in a fixed position or in
linear movement of the product.
Roll on:
The label is dispensed and moved until touching the roller of the roll
on pad. In the labelling position, this roll is pressed onto the product.
Then the label is applied and rolled on by the movement of product.
Press the key to move to the next parameter.
The applicator can be operated in two different ways concerning the
order of printing and labelling within one labelling cycle.
Print-Apply:
The print of a label is released by an external start signal. At the same
time the vacuum on the pad as well as the supporting air from the
blow tube are switched on. If the label is printed and picked up
completely from tamp, the supporting air is switched off and the lift
cylinder is controlled to move the pad down towards the labelling
position. A sensor signals when the labelling position is reached.
Following, the vacuum is switched off and the label is transferred to
the product. After applying the label, the lift cylinder is so controlled
that the pad is again moved back to the starting position.
Now the labelling cycle is finished.
Apply-Print:
Before starting the cyclic operation 'apply-print', the printing and
picking up of the first label has to be released separately by a special
signal.
The pad with the printed label is in starting position and the vacuum at
the pad is switched on.
At start of the cyclic operation when sending the start signal, the first
label is already on the pad. The following process is similar to the
mode 'print-apply' but at the end of the cycle the next label is printed
and picked up by the pad.
Now the labelling cycle is finished.
