online OPSS-1 ****osity, permeability scanning systems for
substrates
Patent pending DE 102.51.610.3 - China as well
Introduction
A German-Thai high-tech, engineering company has developed an optical
online ****osity or permeability scanning system. It works with two
different multiple sensors units, i.e. precise line laser, colour
sensors and internal controller unit for real-time positioning and
****osity control in light transmission mode whilst scanning across the
fast running webs up to 600 m/min.
The main advantage compared to existing technologies is the
measurement of perforation zone/line positions and ****osity levels in
the same time while the scanner system across the running material web
up to 2000 mm width.
Science, R&D, Universities, industrial partners for a licence
agreement and / or technical co-operation are sought.
Working principle
The ****osity control of natural ****ous and/or perforated web material
in laser or electrostatic perforation systems which are produced in
speed ranges up to 600 m/min and web widths up to 2000 mm is difficult
to measure with pneumatic systems because of following disadvantages:
web tangency, web toughing, material flaking, formation of folds, dust
and dirt entering the system.
These difficulties can be overcome with stationary or scan, optical
****osity measurement systems for ****osity ranges from 80 up to 5,000
Coresta units (ml/2cm2/min) respectively 3 to 50 l/m2/Sec.
(Franksystem) by nano, micro or macro holes sizes from 0.5 up to 500
microns and hole densities from 10 macro holes per cm up to 400 holes
per cm2.
The optical online ****osity control technology is designed to scan
perforation zones with a multiple sensor and their positions with a
precision line laser to determine all data in real time with an
internal controller unit. It controls roll material or bobbin formats,
either as a stand-alone unit or mechanically coupled with existing
scanning units which measure the material weight, thickness, opacity,
density, brightness, smoothness, formation, etc.
By laser and electrostatic perforation in bobbins and wide paper web
formats optical online control processes and their devices are
indicated with transverse movements across the web and simultaneously
collections of perforation positions and ****osities by two different
sensor systems.
Both measuring systems move transversely between 50 up 400 mm/Second
over the fully web width. They consist of a line laser detect the
quality and position of single holes, groups of holes or defined
perforation zones into the measuring gap of 5.0 mm. At the same time,
the multiple light transmission sensors monitor all ****osity profiles
and determines envelope curve and calculate the integrals.
Applications and Advantages
Thus direct feedback into the perforation system makes it possible to
compensate any changes in terms of ****osity and perforation locations
so that each jumbo production roll up to 25,000.00 meters as well
single or quadruple bobbin sets can be produced and controlled without
intermediate stops and certificated in quantity und quality on their
end.
Natural ****ous or perforated web material as cigarette, tipping, plug-
wrap, filter, packaging, coated paper as well micro or macro
perforated plastic films as BOPP, LDPE, PP, EVA, HDPE, etc. are
controllable with the OPSS-1 scanning system.
