1.1) UNWINDER
The SV201 unwinder is a suitable non-independent unit for the use of rolls with diameter max. 1000 mm and width 1620 mm.
This is suitable to be connected to any machine for processing material in the form of a film.
It is mainly composed of the following sub-groups:
A) Self-centering pneumatic expansion shaft: to be fitted inside the reel to be processed. It has the task of supporting the reel in the car and transmitting the braking moment provided by the transmission to the reel itself.
B) Hydraulic lifter for reels: used for loading the reel to be processed into the machine; composed of two sturdy steel levers which, controlled by two hydraulic cylinders, lower to allow the operator to position the reel in correspondence with their range of action and rise by raising the reel axis to the same height as the transmission. Once the reel is raised, the operator rolls it up to the transmission connection joint and blocks the bearings using the specific caps. To this the operator connects the reel axis to the transmission through the mechanical joint provided.
C) Eccentric roller: used to correct any parallelism errors of the film after having drawn in the material.
Using this roller, small errors in the parallelism of the material can be recovered, which have arisen during the insertion of the same inside the machine.
D) Tape stop bar: used during machine stops to prevent uncontrolled movement of the film inside the group and / or the machine. It is composed of a simple steel bar with a rubber strip that presses the film onto the underlying roller blocking its movement. The control of the bar is automatically managed by the machine during the work cycle, while it can be managed by the operator during the feeding of the material or during moments when the machine is stopped. The clamping of the material through this group is always and in any case bound by the condition of working speed = 0.
E) Tension control: used to maintain a constant tension when processing the material in the machine.
Consisting of a roller called "dancer" mounted on a pneumatically controlled leverage and automatically managed by the machine according to the parameters set by the operator. With a constant control pressure, the leverage tends to oscillate during the processing of the film, compensating for any stretching of the material, accelerations and / or decelerations of the machine or low or excessive tension of the
material.
F) Transversal register: used to correct the misalignments of the film with respect to the position defined during the drawing in of the material. The unwinder unit rests on the ground on two steel plates on which it
slides transversely as it is mounted on four wheels. The transverse register is basically composed of two parts:
1) an electronic part for reading and controlling the position; a sensor for reading the reference edge and an electronic control and feedback panel;
2) a mechanical / hydraulic control and handling part; a hydraulic power unit and a hydraulic cylinder for the movement of the unwinder.
Once the material has been drawn in from the unwinder to the rewinder, the operator places the sensor on the edge of the material and calibrates the reference value to be maintained throughout the processing
cycle on the electronic panel of the register itself. Once the "EDGE GUIDE" function is activated from the electronic register panel, each movement of the tape along the reel axis determines a
3.3.1.2 Machine(Embosser)
The subgroups that compose it are the following:
A) Feeding with pressure roller: used, as the name suggests, to pull the material from the unwinder towards the machine. The description is the same as in the latest instruction manuals.
B) Idle roller with load cell: used to detect the tensioning of the material. By communicating with the machine software, it has the task of retroacting the braking action of the unwinder
C) Film cleaning group or "TEKNEK group": used to clean the film from possible residues of dust or "slag".
The description of its functions is present in the instruction manual of the Ns. comm. 1018. On the auxiliary push-button panel of the embosser located in correspondence with the control console
1) -Key «INSERT INTERNAL ADHESIVE». Approaches (light on) or detaches (light off) the central (rubberised) rollers of the cleaning unit when the belt passes;
2) -Key «EXTERNAL ADHESIVE INSERTION». Approach (light on) or detach (light off) the external rollers (with double-sided adhesive film) to the internal rollers. This function can only be used after activating the
"INSERT ADHESIVE INSIDE" function. Both controls are then associated with a pneumatic adjustment managed by the operator himself on the
same control panel.
D) Tension control: placed before the first thermal calender used during machine stops to compensate for the material which, as described below, is detached from all the hot rollers on the machine. (the concept is
very simple, but difficult to explain in a few words, I therefore recommend that you discuss it personally);
E) Preheating calender: used to preheat the film before carrying out the embossing process. As mentioned, this is one of the three hot rollers present on the machine, therefore it is necessary that the material does
not remain in contact with it during machine stops. To do this, on the axis of this group there is a toothed wheel which, activated by a gear motor, has the task of moving two rollers whose arc of action allows the
material to be detached from the roller before the machine stops. To better understand the movement.
F) Quick release rollers: as already mentioned in the previous group, these rollers have the task of detaching the material from the thermal calender during periods of machine stop. From the drawing above
it can be seen that there is another roller in addition to those positioned on the preheating grille. This roller allows you to perform the same function as the first two, but in the section of material that is inserted into the embossing unit. This roll is simply supported by the entire embossing unit which, detaching just before the machine stops, raises the roll itself (normally it remains hidden under the passage of the material).
G) Embossing calender: this is the heart of the machine; used precisely to engrave the material to be processed. This roller is mounted on two shoulders which slide vertically on recirculating ball guides. The
handling and the embossing pressure are impressed by two hydraulic pistons. The embossing roller presses the material between itself and the idle roller, engraving the material that passes through them.
H) Idle embossing roller: used to ensure constant pressure of the embossing roller along the entire width of the web. This roller is idle and then driven by the embossing calender and the counter-roller which, during hot engraving, impart a rotary motion to the idle roller itself. The peculiarity of the idle roller is given by the special rubber coating resistant to high temperatures that allows the material to be embossed without
putting the embossing roller in contact with the counter-roller.
I) Adjustment screw: it is a manual control that can be managed directly by the operator; By means of two hand wheels positioned on the operator side and on the transmission side in front of the embossing unit, it is possible to define the embossing depth in thousandths. Each hand wheel allows the nanometric vertical movement of the embossing calender.
L) Cooled roller: used to guarantee a thermal contrast to the embossing process.
M) Idle roller with load cell: used to detect the tension of the material. By communicating with the software of the machine, it has the task of retroacting the braking action of the embossing unit towards the
cooling calender used as an auxiliary drive
N) Cooled calender: used downstream of the embossing group to cool the material after hot working. As already mentioned in the point
3.3.1.3 WINDER
This group is mechanically very similar to the single axis unwinder described above; The only differencefundamental is given by the supporting structure and by a group additional called rolling. The winder is therefore composed mainly from the following sub-groups: A) Self-centering pneumatic expansion shaft: to be fitted inside the cardboard core on which to wrap the finished product. It has the task of supporting the reel in the machine and transmitting the driving moment provided by the transmission to the reel itself.
B) Hydraulic lifter for reels: used to unload the processed reel from the machine; composed of two sturdy steel levers which, controlled by two hydraulic cylinders, are positioned in axis with the finished reel
allowing the operator to unload it by performing the procedure envisaged for loading (in the unwinder) in reverse. This group is exactly the same as the one mounted in the unwinder.
C) Eccentric roller: used to correct any errors in the parallelism of the film after having run in the material.
Using this roller, small errors in the parallelism of the material can be recovered, which have arisen during the insertion of the same inside the machine.
D) Tape stop bar: used during machine stops to prevent uncontrolled movement of the film inside the group and / or the machine. It is composed of a simple steel bar with a rubber strip that presses the film onto the underlying roller blocking its movement. The control of the bar is managed automatically by the machine during the work cycle, while it can be managed by the operator during the feeding of the material or during the moments when the machine is stopped. The clamping of the material through this group is always and in any case bound by the working speed condition
E) Tension control: used to maintain a constant tension when processing the material in the machine.
Consisting of a roller called "dancer" mounted on a pneumatically controlled lever and automatically managed by the machine according to the parameters set by the operator. With a constant control pressure the levers tend to oscillate during the processing of the film, compensating for any stretching of the material, accelerations and / or decelerations of the machine or low or excessive tension of the material.
F) Peripheral contact rolling: used to optimize the compaction of the coils being wound; composed of two sturdy steel levers which, controlled by two pneumatic cylinders, are positioned in support of the initially empty cardboard core, pressing the material being wound during the work cycle. When the machine is started, the rollers come into contact with the cores, at the pressure set by the operator on the pneumatic
panel.
