Description

Sophisticated multi functional inline permeability sensor scanner systems

Patent pending DE10251610 and patent granted in China 200310104764. Stationary or scanner systems for high speed moving fabrics or sheet material to detects very precise and reproduce specified product properties, natural or micro perforated porosity levels during production. OPSS-1 OPRL-1 vision control systems are equipped with multiple IR, NIR, VIS monolithic spectral color sensors, precision line lasers, CCD image devices, DSP, ATMEL, INFINEON sensor internal controller, firmware, serial data link, scanning speeds 20 up to 500 mm per second, web widths up to 5000 mm, measuring gaps from 2.0 up to 5.0 mm, optical inline detection of permeability, porosity, spectral transmission, opacity, extinction, particle absorption, porosities ranges 80 up to 5000 C.U. respective from 50 down to 4 Gurley, position control of micro perforation lines with 0.1mm accuracy, 0.050 up to 200 microns pore diameter by up to 300 pores per cm2.

With real time data determining of certain parameters, optical transmission, spectral grades, porosity integrals, envelope curves, internal calculated measuring values. Thus direct with close loops and feedback to power electronics of fabrics treatment units. Micro perforation or other treatment system makes it possible to compensate any changes in web treatment parameters and their partial locations so that each jumbo roll as well single, twin or quad bobbin sets can be produced quantity and quality controlled without intermediate stops in order of ISO-9001, ISO-9002 certifications.

Working principle and application
Thus sophisticate, precise, liable, repeat accuracy, easy visualized, optical online measurement techniques archives perfect ways to control and convert pneumatic, fluid, gas, jet streams, static permeability, naturally porous grades, filtration levels, breathable or ventilation effects. Their conditions can be easily met by using optical transmission technology thanks to described processing in full online stationary or scanning control units, extremely small pore dimensions, high fabric speeds up to 1000 meters per minute by high repetition rates.

That completely independent from base material properties as consistency, coloring, density, formation, pin holes, smoothness, stretching, shrinking, brightness, opacity, spectral property, gauging thickness weight, moisture content and other known influences. Optical inline OPSS-1 porosity sensor scanning systems for permeability cluster control at electrostatic or laser micro perforation machines, with multiple color sensor head, spectral intensity, DSP, FPGA, CCD, one precise line laser, position, material finger print detection, VIS wavelength, touch less measure of opacity, defects, inspection, combines controller internal firm and further PC process software. Uses for filter, tipping, cigarette, booklet, packaging, magazine, newspaper, media, bible, wall, decoration, Kraft, sack, filter, paper, coffee, tea, food, co-extrusion, foil, film, agriculture, cement, maize, rise, pet, domestic or other fast moving web material.
