Print inspection – tipping paper – quad bobbins

Patent applied in Germany and P.R. of China

Sophisticated multi functional permeability sensor systems

Patent pending DE10251610 and patent granted in China 200310104764. Stationary or scanner systems for speed 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, fast serial data link, scanning speeds 20-500mm per second, web widths up to 5,000 mm, measuring gaps from 2.0-5.0 mm, optical inline detection of permeability, porosity, spectral transmission, opacity, extinction, particle absorption, porosities ranges 80-5,000 C.U. respective from 50 down to 3 Gurley, position control of micro perforation lines with 0.1mm accuracy, 0.050-200 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 ISO9001/9002 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 1,000 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, other known influences.

Optical online 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, 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.

Conditions

· tipping paper web speed max. 480 m/min = 8.000 mm/sec.

· printed register field across web : X max. 64 mm

· printed register field down web : Y = 25 mm

· OPSS-1-B scanner speed – e.g. A = 200 mm/sec

· camera scanner speed – e.g. B = 600 mm/sec.

· position accuracy of OPSS-1-B scanner : +/- 50 µm with ASM sensor

· OPSS-1-B scanning stroke approx. 300 mm

· local resolution at printed field = 100 µm

· suggested pixel sensor (double pixel calculation)

· X = 2*(64mm/0.1mm) = 1280 pixel

· Y = 2*(25mm/0.1mm) = 640 pixel

Results

maximal capture rate : cap = speed/Y-field = 8.000 mm/sec/25 mm = 325 capture/sec.

inspect with step 1 bobbin A : (Δt0 --- t1)*cap = 0.32s*325 capt/sec. = 104 captures while web running

inspect with step 2 bobbin C : (Δt3 --- t2)*cap = 0.32s*325 capt/sec. = 104 captures while web running

inspect with step 3 bobbin D : (Δt3 --- t4)*cap = 0.32s*325capt/sec. = 104 captures while web running

inspect with step 4 bobbin B : (Δt1 --- t2)*cap = 0.32s*325 capt/sec. = 104 captures while web running

(Δt0 --- t1) = (Δt1 --- t2) = (Δt2 --- t3) = (Δt3 --- t4)

full scan OPSS-1-B : 2*(∑t1, t2, t3, t4) = 1280*2= 2560 ms = 2.56 sec.

by (2.56 sec.*8 m/sec) 20.5 meters printed tipping paper by full scan

∑ captures : (step1+step2+step3+step4) = 4*104 captures = 404 captures

Continuous inspect length by bobbin A, B, C, D: speed*inspecting = 8.000 mm/sec*0.32 sec = 2.6 meter

Continuous inspect printing length of each bobbin strip : 2.6 meters with 104 captures

each of 25 mm single printed fields by 8 m/sec. speed
