Piston position sensors Down / Up
Sensor (
2.2)
acts as a position/contact sensor, can be
adjusted to increase/decrease contact pressure of the label
pad
(5)
against the product, moving the sensor up/down
±4mm.
The piston has an adjustment
(3)
to limit the maximum
movement (400mm) as a security element to avoid hits on the
line o as a waiting point when using blow labeling.
Sensor harness, piston movement air tubes and vacuum/blow
tube moves inside a guided chain
(4)
.
This guided chain and the special mounting piston as a
monoblock allow the P&A to be used on any position without
further adjustments.
Tubes and harness comes to the control unit
(10)
inside a helical tape to prevent damages
(8).

Label pad
The unit comes with 100x100mm or 110x150 Label pad without holes. This pad should be
customized depending on customer’s label(s). The unit is factory adjusted, ready to work
(after label pad customization) and offers XYZ regulation

up/down and
forward/backward

Air blow tube
‘air-assist’
While printing keeps the label parallel to the label pad, the blowing point is positioned on the center of the
label around 1/3 of the label. When using EX4T1 the position is fixed on the label center. For EX4T2 label is
left side position.
When testing, when the printer is ready to print, there is a test button
(9)
to print & apply one label and check
than the label pad
(5)
and air assist
(11)
are suitable. Also there are other configuration parameters available
on the configuration menu accessible with the operation panel
(10)
(see user’s manual).

(10)
can be adjusted over the label exit on
Horizontal
(3.1)
and Vertical
(3.2)
; also with the
air assist orientation adjust over label path

we can adapt the unit to any condition.
Also time parameters can me modified using
operation panel

When working in 'contact' mode, pressure can be set moving up/down piston sensor

loosening/tightening
the flange that holds it.
Also the piston stoppers can be set up

depending on the speed of movement to act before/after
smoothing the piston
