ExVis is the basic software of the ALPINE
Process Control
This high performance software enables the collation, visualisation
and filing of extrusion process data.
|
The complete extrusion line is displayed on the monitor. ALPINE
equipment is controlled by means of Siemens PLC equipment which
intercommunicate via a Siemens profibus. Entry of data is effected
via a touch-screen and a keyboard. Operating data are prepared
of bus-data transfer via defined interfaces. The display of
all data is effected either graphically or numerically. Alarms
and error messages are displayed in the same way.
ExVis contains a database which enables
all data to be displayed in a diagram as a function of time.
Evaluation and analysis of data is thus much simplified. Trends,
film formulations etc. can also be stored.
OrVis is a software for the control and visualisation which
was developed to control the orientation process in ALPINE monoaxial
orientation lines. It works autonomously in out-of-line units
or under ExVis on in-line units where the data are supplied
to the ExVis databank.
ProVis is software developed to control
the POS system which improved the film thickness profile. It
can operate autonomously or under ExVis.
The POS system consists of the following
hardware components:
To ensure optimum film quality. The
film profile is measured, controlled, visualised and documented.
Profile measurement is effected with
sensors in contact or optionally without contact to the film.
Depending upon requirements the sensor is either mounted on
a reversing unit or in the film collapsing system.
The CRS is an additional cooling ring
with an independent blower. The air exiting from the cooling
ring is divided into segments. Stepless solenoids regulate the
amount of cooling air which effects the film thickness in the
independent segments.
The TRS is an alternative to the segmented
cooling ring. Independently controlled heater cartridges control
the temperature profile around the circumference of the die.
Advantages of a POS system:
- Rapid improvement of the film thickness tolerance
- Secure and reliable operation
- Improvement of the winding quality
- Improvement in machinability in downstream equipment
All hardware components of the ALPINE profile control system
can be retrofitted to existing lines.
