Intelligent Vision for Calender Control |
| |
|
IVCC is the solution to automatically keep the material
between the first two cylinders of a calender
› Constant
in terms of the total quantity, and
› Homogeneous
in terms of its distribution between the stock guides.
The system is based on thermography to ensure a perfect
regulation of the system with any PVC color, any type
of illumination (daylight, or artificial), and in presence
of vapours. The IR camera simplifies the settings and
the user interface related to image capture and image
processing.
The system architecture is open, and it may be adapted
to the specific needs of any calendering line. Typical
controlled variables are the speed of the extruder and
the lengths of the pauses of the calender wig-wag conveyor
(left, centre, right).

| System Benefit |
 |
|
› Decrease
of the scrap because of
- Decreased time required to reach production steady
state at each change of the manufactured product (thickness,
blend, width, ...)
- Reduced width of the trimming edges
› Improved
thickness control (narrower thickness distribution)
and overall quality of the product
› Decreased
time spent by the operator to control the bank
› Reduce
the likelihood of contact between the cylinders due
to lack of material.

| Application
Sectors |
|
| The system
may be used to control the feeding stage of any calender
laminating line, such as for PVC film/sheet production,
or for polyolefin resin processing, or for rubber production
(tire, belt). |
