2.1 Controls
2.2 ADJUSTMENT PARAMETERS ( user’s tactile terminal)
INTRODUCTION
The functioning and adjustment parameters of the machine are done through
the user’s tactile terminal, connected to the control of the machine.
This tactile terminal allows the display of the functioning parameters of the
machine (working speed, production data, etc.), and also the selection and
adjustment of the functioning of the machine.
In the tactile area, texts, numeric data and images are shown. Moreover it is
also possible to include tactile push buttons and selectors.
A tactile push button is an area in the screen with an image, by touching this
image, an action is carried out (for example “pgUp/pgDn”, reset of the counters,
etc).

A pop up window is opened directly on the screen. These screens can be
opened or closed by using a switch, tactile push button, etc. The pop up
windows are composed by three items: folders, groups and panels. It is also
possible to open a pop up key board to introduce data. They will be closed by
touching them.
1. By pushing on this image you will go to the pop-up screen
where address is displayed.
A tactile selector is an area in the screen with an image. This image is not
fixed; it changes depending on the selected option of functioning mode. By
touching this image, this option can be changed. This is used for OFF/ON,
AUTOMATIC/MANUAL, and etc selectors.
The numeric data can be either of only read-out or modifiable. To change a
modifiable data, you will only have to touch it and a numeric keyboard will
appear where the new value will have to be introduced. Once it is introduced,
push ENT to confirm or ESC to cancel the modification and go back to the page
displayed before.
When the machine is switched on for the first time, a presentation page
appears. Afterwards it goes over to the menu pages where it is possible to go
over to several adjustment pages, placed into groups, depending on the type of
operation or handling of the machine that is wanted to be controlled.
In this way, from the menu page, it is possible to go to the speed adjustment
pages, profile feeder, production details, etc.
To go to each one of those adjustment pages, from the menu page, the
corresponding tactile button on the screen will be touched. Those buttons will
be identified with an icon, related with the page to which you want to go.
Apart from the buttons to go to the different adjustment pages, there are several
tactile buttons, of main use. The most frequent ones are the following:
-“Page advance”. When you touch this icon, you go the following page
of a related page sequence.
-“Page return”. When you touch this icon, you will go to the former
page, this means, to the page from which you come.
-“Value increase”. This button is always placed where there is a
numeric value. Each time that this button is touched, the numeric data
will be increased with 1 unit.
-“Value decrease”. This button is always placed where there is a
numeric value. Each time that this button is touched, the numeric data
will decrease with 1 unit.
-“OFF Selection button”. Image of an OFF/ON button, when the related
parameter is in OFF position.
-“ON Selection button”. Image of an OFF/ON button, when the related
parameter is in ON position.
-“AUTOMATIC Selection button”. Image of an AUT/MAN button, when
the related parameter is in AUTOMATIC mode.

-“MANUAL Selection button”. Image of an AUT/MAN button, when the
related parameter is in MANUAL mode.
Hereafter, we will describe the different handling of the machine that have to be

NOZZLE HEAD
The machine has a nozzle head for glue application on the foil.
The head has two electrovalves: one for the opening and glue feeding and the
other for the approach, so that the nozzle approaches to the foil.
At the moment that the electrovalve for the nozzle opening is set on, the control
sends automatically a signal to the premelter so that the pump starts and sends
glue. With the grammage control system, the speed of the premelter pump is
regulated.
With a selection button I-O-II, placed in the control panel, two working modes
can be selected:
-MANUAL. Only for maintenance works. Only the head opening electrovalve
is set on.
-AUTOMATIC. It is the working mode. When workpieces start to enter in the
machine, and if the foil is prepared, the control approaches the head to the
nozzle and the pump is set on, that will apply glue on the foil for the
wrapping process.
There is a safety photoelectric cell placed nearby the nozzle head. This cell
detects the presence of foil. If, during the AUTOMATIC working mode, one of
this does not detect the foil, the nozzle closes immediately and it moves back
and it stops to apply glue.
The tactile buttons and associates images for the nozzle head handling are the
following:
1. Close the popped up screen.
2. ON / OFF selection foil brake security.
−Approach.: Counter to approach the nozzle. This counter is for the
adjustment of the moment that the nozzle approach starts, from the
moment that profiles come into the machine.
−Disapproach: C Counter for the nozzle to move back. This counter is for
the adjustment of the moment that the nozzle goes back to its initial
position, from the moment that the last profile gets into the machine.

GRAMMAGE CONTROL
This system allows the automatic adjustment of the glue dosing with the nozzle,
thanks to the speed adjustment of the premelter pump.
The pump of the premelter equipment works within a margin of 0 to 100 r.p.m.
For its command, the control gives an analogical speed signal from 0 to 10
Volts. This signal has to be connected at the external signal of the speed
command of the pump.
The user will only have to introduce the quantity of glue that he would like to
use, this means, the required grammage and the lamination width that he will
work with. With those details, and depending on the speed of the machine, the
control adjusts the turning speed of the pump, to obtain the quantity of glue
programmed before.
This system ensures that, independently from the speed of machine, the nozzle
always gives the glue quantity wished.
The system allows also choosing between two working modes:
−MANUAL: In this mode the pump works always at a fixed speed,
programmed by the user. In manual mode, the pump always turns at the
same speed (in r.p.m.), independently from the speed of the machine or
the lamination width.
−AUTOMATIC: The grammage control system adjusts automatically the
speed of the pump, according to the glue quantity (grammage) that
wants to be used.
1. Grammage. In this numeric field, the quantity of glue that you want to
apply, is introduced. It is given in gr/m2. This data is used in automatic
mode
2. Laminating width. Foil width, expressed in mm, to which the glue is
applied with the application nozzle.
3. Pump speed. In this graphic bar, the actual turning speed of the pump of
the premelter is displayed. It is a read-out parameter. AUTOMATIC /
MANUAL selection mode.

4. Manual speed. Turning speed of the pump when manual mode is
selected.
5. By touching on this button, you will be able to go to the rest of the
parameters of pump information.
1. Glue density. Given in grs/cm3. Normally, it has to get adjusted
with the value 1.00.
2. Pump constant. In this field the pump capacity has to be
introduced. It shows the cm3that the pump moves in one
revolution. This data has to be given by the manufacturer of the
premelter.
3. Pump speed. In this graphic bar, the actual turning speed of the
pump of the premelter is displayed. It is a read-out parameter.
AUTOMATIC / MANUAL selection mode.
4. Work voltage pump. Selection of the volts you wish the pump to
work with. The pump has two working voltages, 0-5 / 0-10 Volts.
LAMPS
The lamp functioning selection is done through a touch screen.
For an automatic start of the lamps, several requests have to be met, being the
following:
−Detection of the photoelectric cell at the entry or, if this is not present,
the start of the profile limit switch.
−Touch button for the selection of the working of the lamp in ON, by
connecting this way the functioning of the lamps.
−The machine conveyor has to be connected.
The lamps will stop functioning once the number of impulses of the lamp stops
counter reaches the number of impulses introduced on the screen. This counter
will start when the entry photoelectric cell does not detect anymore, or, if this is
not present, the profile limit switch stops.

Moreover, the lamps have a preheating function. This function consists of the
start-up of the lamps with the push-button LAMPS MANUAL. Once this button
is pushed, if the lamps are activated, these will start-up and stop automatically
after two seconds. Bear in mind that if, during those two seconds, a workpiece
would be introduced in the machine, the preheating function would be cancelled
and the lamps would stop due to the encoder impulse counter.
The start and stop of the conveyor motor is done through push-buttons ON /
OFF placed in the control panel.
1. Close the popped up screen.
2. OFF / ON lamps selector.
3. Number of impulses counted by the machine until the lamps stop,
once they have started and when the photoelectric cell at the
entry of the machine does not get any signal any more. This field
can be modified.
LEISTERS
The leisters functioning selection is done through a popping up screen.
o that the leisters are automatically activated, some requests have to be
accomplished:
−Detection of the photoelectric cell at the entry, or if this is not
installed, driving of the limit switch of the profile.
−Touch button for the selection of the working of the leisters in ON,
by connecting this way the functioning of the leisters.
−Conveyor of the machine functioning.
The leisters will stop once the number of impulses of the stop counter reaches
the introduced value on the screen. This counter is activated when the
photoelectric cell is not detected anymore, or if this is not present, when the
limits switch stops.
