Nano Mikro Cluster Technologien für Materialbahn Veredelungen

Zur Atmungsaktivierung, Wasserdampfdurchlässigkeit, Gasaustausch oder Ventilation und unter anderem zur Beibehaltung der Wasserdichtigkeit werden Produkte wie Verbundstoffe, Zigaretten-, Filter-, beschichtete Spezial-, Kraft-, Sack- oder Verpackungspapierbahnen, Vliesstoffe oder technische Textilien mit Flächengewichten von 20 g/m2 bis zu 140 g/m2 elektrostatisch Nano oder Mikro sowie mit feinen Laserstrahlen Mikro oder Makro perforiert. Unter elektrostatischer Nano oder Mikroperforation sind statistisch unregelmäßig verteilte, in der Größe, wenn gewünscht, mit bis zu 40 % variierende und analog hierzu unter Laser Mikro oder Makro Perforation, gleichmäßig angeordnete und im Durchmesser etwa gleichgroße, nach Möglichkeit runde, gradfreie Löcher und Lochreihen verschiedenster Anordnung zu verstehen.

Bei der elektrostatischen Perforation finden im bis 1.5 mm weiten atmosphärischen Elektrodenspalt der meist dünnen oder spitzen, gegenständigen Elektrodenstifte Blümlein- und dielektrisch geförderte Mikroendladungen mit Filamentierung zur Erzeugung eines Plasmentunnels und sich damit aufbauenden, ionisierten Funkenstreckenkanal im Nanosekundenzeitfenster statt. Mit jeder hochspannungstechnischer Entladung und Deionisation im Spannungsbereich bis zu 50.000 Vss, deren Leistungselektronik patentiert ist, entsteht für die im Elektrodenspalt relativ schnell durch bewegte Materialbahn eine elektrostatische Nano oder Mikroperforation mit präzise gesteuerten Energieanteilen von 0.1 bis 3 mJ pro erzeugter Pore, die mit bloßen menschlichen Auge unsichtbar sind und vollflächig wie auch zonenförmig in bestimmten Abständen über die Bahnbreite verteilt sein kann.

Mikroperforationscluster

Lochgrößen bewegen sich dabei im Durchmesserbereich von 50 nm - 80 µm bei Lochsequenzen von 1.5 – 16 Million Poren pro Sekunde. Zonenanordnungen sind in Breiten von 2 bis 6 mm bei Porendichten von 120 - 250 Poren/cm2 erreichbar, wobei Flächenperforationen oder so genannte Nano- oder Mikrocluster Lochdichten bis zu 3 Million Poren/m2 oder 300 Poren/cm2 generieren.

Die so erzeugten elektrostatischen Mikroperforationen ermöglichen Porositätsbereiche von 80 bis 2500 C.U. ( Coresta Unit ml/2cm2/min ) oder respektive 30 – 6 Gurley bei Materialbreiten von 100 bis 2000 mm und Bewegungen bis zu 500 m/min, abhängig vom Luft- oder Gasdurchsatz und Materialkonsistenz, welche die Perforierbarkeit bestimmt. Mit zwei oder drei Multisektionen von elektrostatischen Mikroperforationseinheiten und simultanen Doppelmaterialbahndurchlauf innerhalb jeder Sektion lassen sich Produktionsausbringungen je nach Materialart, Flächengewichten und Perforierfreudigkeit von 1000 bis 4000 Tonnen pro Jahr erreichen.

Produktanforderungen

Grundsatzforderungen für Produktapplikationen mit Verbundstoffen, Vliesstoffen oder Verpackungsbahnen welche Notwendigkeiten von Gas- oder Wasserdampfdurch- aber Wasserundurchlässigkeiten verbunden sind, fordern den Einsatz der elektrostatischen Nano Mikroperforation regelrecht heraus, da Wasser oder andere Flüssigkeiten die relativ kleinen Nano- oder Mikroporen von z.B. kleiner als 0.5 - 5 µm Durchmesser aufgrund der hydrophoben Oberfläche das Produktmaterial nicht penetrieren kann.

Diese und weitere physikalische Vorteile der kleinen Poren und hoher Dichte lassen ermöglichen einen vorteilhaften Industrieeinsatz, da Erfüllungen zur Atmungsforderung und Wasserdampfdurchlässigkeit z.B. nach den ASTM E96-80 oder E96-84 Messmethoden mit 100 – 800 g/m2/Tag mit Laserperforations- oder anderen Prozessverfahren nur äußert schwierig und technologisch aufwendig machbar, zu teuer, zu unwirtschaftlich oder bei derart hohen Lochdichten technologisch keinesfalls erreichbar sind.

Anwendungen

Elektrostatisch Nano oder Mikro perforierte Verbundstoffe, Packmittel oder Folienverbunde verschiedenster Art lassen sich beispielhaft für folgende Produkte und Applikationen verwenden.

Perforationsbeispiele Verpackungsbahnen

Berechnungen für Flächenperforationen

Grundformeln zur praktischen Auslegung einer Anlage

• (1) Anzahl der Elektrodenpaare : INT ( Bahnbreite (m) / ( K-Ab * n-Stifte-E ))
• (2) Porendichte : (Summe-Estifte * f ) / ( BB (m) * Vb (m/s) )
• (3) Porenabstand in Laufrichtung : Vb (m/s) / f (1/s)

Formelzeichen

• K-Ab        = kleinster Lochreihenabstand in Bahnquerrichtung, z.B. 0.8 mm
• n-Stifte-E = Anzahl der Elektrodenstifte pro Elektrodenpaar, z.B. 12, 24, 32, 48
• Vb            = Bahngeschwindigkeit in m/s
• F              = Repetitionsfrequenz der Funkenstrecken in Hz, z.B. 4000 Hz, 6000 Hz, 10.000 Hz
• BB           = Bahnbreite in Meter

Berechnungsbeispiel

• Bahnbreite = 1m, Bahngeschwindigkeit = 300 m/min = 5 m/Sek., f = 6000 Hz,
• K-Ab = 0.8 mm ( min. Abstand in Querrichtung ), n-Stifte-E = 48
• (1) = INT ( 1000 mm / ( 0.8 mm * 48 )) = 26 Elektrodenpaare
• (2) = ( 48 * 26 * 6000 1/s ) / ( 1 m * 5 m/s ) = 1.497.600 Poren/m2
• (3) = 5 m/s / 6000 1/s =  0.83 mm Porenabstand in Laufrichtung

Zusammenfassung

Nur die elektrostatische Mikroperforation ermöglicht durch fein dosierte Energieeinkopplung und Funkenkanalerzeugung eine nano oder mikrofeine Ventilation für Packmittel mit erhaltenen Barriereeigenschaften, Schaffung von Atmungseigenschaften für Domestik- und Massenprodukte, industrielle oder medizinische Nano oder Mikromembranen mit Mikrocluster, Vliesstoffe und insbesondere Papierbahnen verschiedenster Art bei relativ großen Bahnbreiten und Transportgeschwindigkeiten, welche aus physikalischen oder prozesstechnischen Gründen nicht mit anderen Verfahrenstechniken erreichbar sind.

Dieser Trend wird sich für spezielle Produkteigenschaften und Anwendungen fortsetzen. Die state-of-the-art, industrietaugliche und im Dreischichtbetrieb zuverlässig arbeitende Nano Mikrocluster Perforationstechnik, deren Integrationsmöglichkeit in vorhandene Umroller- oder sonstige Bahnlauf- und Materialbewegungsanlagen sowie auch als völlig eigenständig arbeitende Produktionsmaschinen möglich sind, wird zukünftig neue Anwendungsbereiche erschließen und Produkte mit besonderen Eigenschaften entstehen lassen.

Durch Weiterentwicklungen von hybriden, modularen Schaltungstopologien mit IGBT, MOSFET, FRETFET oder HVFET zur Erzeugung stromgesteuerter Hochspannungsentladungsimpulse im Zeitfenster von 10 ns bis 15 µs und Pulsendladungen von 0.1 bis 3 mJ hat die Nanotechnologie und Submikroperforation auch im Bereich der Feinpapierveredelung und Verpackungsstoffverarbeitung Einzug gehalten. Auf die anderen zuvor genannte Applikationsbereiche ist dies für die beschriebene Mikroclustertechnologie übertragbar.

Details http://www.microperforation.com/igbt-esp-unit.html

Kunststofffolien wie PE, PP, PVC, LLDPE, BOPP, EVA, MVA, MOV, MOH, FEP, HDPE lassen sich auch zukünftig besser mit hot oder micro needle oder anderen mechanischen sowie mit Gasendladungs- oder Festkörperlaser gesteuert perforieren. In diesem weiten Applikationsspektrum ist es denkbar auch dahingehend entwickelte, angepasste Laserperforationssysteme für Breitbahnen bis zu 2000 mm und Lochsequenzen über 3 Mil./Sek. einzusetzen.

Laserperforationstechnik

Durch Polygon um gelenkte oder gepulste, fokussierte Laserstrahlen bei vorzugsweise 10.6 µm Wellenlänge sind mit im internationalen Markt angebotenen Anlagen Lochgrößen von 60 µm - 200 μm bei Lochdichten von typischer Weise 10 – 30 Löcher/cm, Lochsequenzen von 100.000 bis 300.000 Löcher pro Sekunde, bei maximal 16 oder 32 Laserlochreihen über die Materialbreite verteilt, realisierbar.  Damit genierte Luftdurchlässigkeitsbereiche betragen 100 – 3000 C.U. bei Materialbreiten in der Regel von 100 – 500 mm bei relativ hohen Bewegungen bis 10 m/Sekunde, abhängig von verschiedenen Parametern.

Laserperforationstechniken von IPM

Mit Entwicklung des patentierten IPM Dual Hochleistung Lasermultiplexers und optischen Eingangsleistungen bis zu 8 KW, bei fast oder slow flow sowie SLAB Laserquellen mit 10.6 μm oder auch anderen Wellenlängen, ist es erstmalig möglich, bis zu 200 separierte optische Laserstrahlausgänge zu realisieren, mit denen unter anderem auch Mikroperforationen und anderen Bearbeitungen wie Schneiden, Schweißen, Bohren, Abtragen, Trennen, Fügen, Vergüten, Polieren usw. in Breitformaten und Substraten bis zu 5000 mm machbar sind.

Dies sowohl in Kunststoffmaterialien, Folien, Papier wie auch in Stahl, Edelstahl, Aluminium, Keramik, Solarzellen, Glas, Kupfer, Messing, Gold, Silber, Silizium, Blei, Bronze, Druckguss, Werkzeugstählen, Holz usw.

Hierbei werden im auf zwei Ebenen aufgebauten optischen Dualmultiplexer mit hoch rotierenden Doppelstrahlteilern bis zu 200 Lasereinzelstrahlen erzeugt und über flexible Hohlfasern dem Bearbeitungsort zugeführt, deren exakte Positionierung ein automatisiertes Robotersystem und motorgesteuerte Mikro Fokussierung beinhaltet.

Bei diesem Lasermikroperforationssystem sind jetzt Lochsequenzen bis zu 2 Millionen pro Sekunde, Lochgrößen von 60 µm - 100 µm, Lochdichten von typisch 10 – 30 Löcher/cm, Porositäten von 100 - 1000 C.U., Geschwindigkeiten bis zu 400 m/min bei Materialbreiten bis 2000 mm machbar. Damit ist eine vorteilhafte Basis geschafft, um 25.000 Meter Jumbo Rollen an der Ab- und Aufwicklung non stopp zu veredeln, was 2000 – 3000 Tonnen/Jahr von Lasermikroperforierten Feinpapieren oder anderen Verpackungsverbundstoffen an der high tech Automation geführten Produktionsmaschine LPM-1 bei geringen Papierausschuss von kleiner 1% mit Qualitätszertifizierung einer jeder Produktionsrolle ermöglicht.

Hierbei ist das patent angemeldete, optische online Permeabilität Prozessmesssystem OPSS-1 in traversierender Ausführung zur präzisen Positionskontrolle aller Laserperforationslinien sowie der moderaten Erfassung aller Porositätsprofile ein integraler Bestandteil der ISO Qualitätskontrolle und Datenauswertung zum Ende einer jeden Produktionsrolle.

Eine weitere, zum patentangemeldete Entwicklung stellt die Mikro-Laser-Line Perforations- und Strahlauslenkungstechnologie MLL-1 dar, welche einen nicht geradlinigen Laserstrahlverlauf und damit verbundene Lochreihenanordnung auf Materialien ohne Galvanometer oder Piezo Aktuatoren bis zu 2000 Hz ausführt. Breite Anwendungen finden sich z.B. für Mundstückbelagpapierblättchen der Zigarettenfilter, RYO, MYO, usw. gegenüber den von seit mehr als zwei Jahrzehnten traditionell stets koaxial verlaufenden Laserperforationen.

In Sicherheitspapieren, Banknoten, Reisepässen, hochwertigen Geschäftsbriefbögen, graphische Papiere, Hologramme, Broschüren, Buchdeckeln, Geschenkkarten, Geschenkartikeln, Kundenkarten, ATM Kreditkarten, Zugangscodes, Kontrollkarten, Herstelleridentifikation, Produktverfolgung, OEM Garantie, Typenschilder, Deklarationen, Firmenpräsentationen und hundert anderen Plastikfolien, Kunststoffe oder metallischen Materialien lassen sich wellenförmige, Zickzack, Rechteck, Dreieck, gewundene Lochreihenlinien, Firmenlogos, Kryptogramme, Scripts, anti counterfeiting Indikatoren, Merkmale, Identifikationen oder andere beliebige Ausführungsformen als Oberflächengravuren, Materialritzungen, Materialabtragungen, Imbedding oder Mikroperforationen dauerhaft mit zeitlich sehr schnell, präzise aus gelenkten Laserstrahlen einbringen.

Für Lasermikroperforationen mit Co2 Laserquellen ist dies bei Lochgrößen von 60 µm - 120 µm, Lochdichten von typisch 10 – 30 Mikrolöchern/cm bei Lochsequenzen von 100.000 - 300.000 Löcher/Sek. und Permeabilitätsbereichen von 100 – 800 C.U. realisiert.

Ventilation von Massenprodukten

Die elektrostatische Mikroperforation ist seit 30 Jahren zur Ventilation von wenigen Nichtfilter- und jetzt für fast alle im Markt befindlichen Filterzigaretten eingesetzt, um gesteuerte Luft Bypass Eigenschaften, dem so genannten Lindströmprinzip, zu erzeugen. Hierzu wird das Zigarettenpapier für wenige Nichtfilterzigaretten z.B. auch Roll-your-own RYO und bei fast allen Filterzigaretten das Mundstückbelagpapier, dem so genannten Tipping aber auch das Plug-Wrap Papierblättchen, elektrostatisch im Offline Verfahren Zonen Mikro perforiert, um gewünschte Poren im Durchmesserbereich von 10 - 70 µm generieren.

Oder mit fokussierten Laserstrahlen in Offline Verfahren Lochreichenperforationen aber auch im Online Verfahren an der Filteransetzmaschine direkt durch das Mundstückbelagpapierblättchen bis in den Zigarettenfilter gewünschte Poren im Durchmesserbereich von 60 - 120 µm einzubringen, um so Nikotin-, Kondensat- und Schadstoffanteile für den Raucher über die gesteuerte Ventilationskombination auf strikt vorgegebene Werte zu reduzieren.

Vor vielen Jahren hat IPM auch zur Online Mikroperforation an Zigarettenherstellungsmaschinen ein Verfahren entwickelt und seinerzeit unter EP0460369 sowie DE4018209 zum Patent angemeldet, welche das Einbringen von Mikroperforationsprofilen über die jeweilige Zigarettenlänge sowie in deren Umfang an beliebigen Stellen des Zigarettenpapiers erlaubt.

Kontrolle von Nano oder Mikro Permeabilität Cluster 

Permeable, naturporöse, Gas- oder Wasserdampfdurchlässige, Nano oder Mikroperforierte Warenbahnen, Verpackungsstoffe oder andere bewegte Materialien bewegen mit Transportgeschwindigkeiten bis zu 10000 mm/Sekunde bei Breiten bis zu 5000 mm, so dass sich pneumatische, Über, Unterdruck oder Jetstream Systeme oder andere Materialberührende Prozessmessungen als online Kontrolle exorbitant schwierig gestalten. Des Weiteren haften den Materialberührenden Messmethoden mögliche Nachteile hinsichtlich Bahnzugserhöhung, Materialabriebs, Faltenbildung, Undichtigkeit im Sensorkopfbereich, starken Verschmutzungen, Nichtlinearitäten und anderen Schwierigkeiten an.

Sensorsystem

Optische online Sensormessverfahren bieten vorteilhafte Möglichkeiten zur spektralen Transmissions- oder Extinktionsmessung für die Bestimmung der pneumatisch statischen Gas- oder Wasserdampfdurchlässigkeit dieser bewegten Materialien, wenn wesentliche Grundkriterien wie z.B. optische Transparenz, Opazität, Spektralverhalten im Bereich von 350 – 900 nm, Porengrößen von 50 nm bis 100 µm, Porencluster bis 500/cm2, Materialdichte, Konsistenz, Glätte, Glanz, usw. erfüllbar sind. Dabei ist das Anforderungsspektrum aufgrund der eingangs genannten Produktkonditionen und online Produktionskontrolle, kleinen geometrischen Porenabmessungen, Gasdurchgängen,   relativ hohen Transportgeschwindigkeiten und wichtiger Messwert Reproduktion mit der optischen Porositätsmessung gut zu lösen.

IPM hat verschiedene optische Messverfahren und Sensorsysteme in stationärer oder Traversausführung als OPSS-1 und OPRL-1 entwickelt, im Markt eingeführt und mit der DE10251610 sowie auch in China 200310104764, DE19542289 zur Patentanmeldung gebracht, mit denen online Produktionskontrollen und Produktzertifizierungen nach ISO 9001, 9002 und dem Statistical Quality Control (SQC) im Reproduzierbarkeitsgrad und Genauigkeiten unter 2% praktiziert sind.

Transmissionsmodus

Damit sind Gas- oder Luftdurchlässigkeitsmessbereiche von 80 C.U. bis 5000 C.U. ( Coresta ml/2cm2/min ) oder 100 – 2 Guley in Kombination von hybrid Multifarb- und Intensitätssensoren, Permeabilitätsprofilerfassungen mit Auflösungen kleiner 0.1 mm mittels integriertem Präzision Linienlaser, CCD Zeile, intelligente DSP und FPGA Multicontroller Sensorelektronik, Firmware, RS 232, RS 485 high speed Links oder CAN, Profibus, Ethernet Busanbindungen bei scanning speeds von 20 bis zum 1000 mm/Sek. ober- und unterhalb des relativ dazu bewegten Materiales im Transmissionsmodus realisiert.

Der angekoppelte Industrie PC und deren Prozesssoftware kommuniziert mit dem OPSS-1 Sensorkopf, steuert gleichzeitig die Travers Achse und deren controller und übernimmt ebenfalls die Trendnachführung als feed-back close-loop Steuerung zur gravierenden Einengung der Produktmessgröße. Unterhalb der bewegten Materialbahn befindet sich auf gleicher X/Y-Achsenlinie die Beleuchtungszuführung, welche über eine spezielle Lichtfaser der chromatischen Lichtquelle zugeführt. Messspalte in Z-Richtung sind bisher im Bereich von 2 – 10 mm praktiziert, größere Abstände sind auf Anfrage und optische Vortestung der Materialkonditionen denkbar.

Permeabilitätsprofile

Des Weiteren bietet das OPSS-1 Sensorsystem auch die Möglichkeit, nicht nur lokale Permeabilitäten, Nanodurchlässe, Massenporen, Mikrokanäle oder Mikroperforationszonen, stationär kontinuierlich zu messen, sondern auch auf einer travers bewegten Einheit eine Vielzahl sequentiell nebeneinander angeordneten Messzonen, Bereiche, Permeabilitätscluster und Vollflächenbereiche bis Materialbreiten von 5000 mm automatisiert zu detektieren und Messwert gerecht auszugeben.

Andere Messgrößen wie z.B. die WDD nach ASTM oder ISO in g/cm2/h, Liquid, Jet Stream Penetration, Feuchtigkeitsverhalten, Partikelretension, Photonenstrom oder andere physikalische Eigenschaften sind nach entsprechenden optischen Voruntersuchungen möglich, sofern die Materialien eine bestimmte optische Transmission im gemessenen Wellenspektrum aufweisen und das Verhältnis zwischen Nutzsignal und Untergrundrauschen 18 – 28 dB oder besser beträgt.

Optische Permeabilität Porositätsmessung
 

Da die naturporösen oder zu perforierenden Bahnmaterialien sich mit Bahngeschwindigkeiten bis zu 600 m/min und in Bahnbreiten bis zu 2000 mm bewegen, gestaltet sich eine pneumatische, also bahn berührende Porositätsmessung, exorbitant schwierig. Hinzukommend sind diese Messmethoden mit Nachteilen der Bahnzugserhöhung, des Materialabriebs, Faltenbildung, Undichtigkeit im Messkopfbereich, starken Verschmutzungen, Nichtlinearitäten und Schwierigkeiten stets verbunden.

Daher bieten sich optische Messverfahren zur Transmissionsmessung als Funktion der pneumatisch, statischen Gasdurchlässigkeit für naturporöse oder Nano, Mikro bzw. Makro perforierte Bahnen an. Dabei sind die gestellten Anforderungen aufgrund der eingangs genannten Produktverarbeitung und online Kontrolle, extrem kleinen geometrischen Porenabmessungen, relativ hohen Bahngeschwindigkeiten und guter Messwertreproduktion mit der optischen Porositätsmesstechnik in idealer Weise zu lösen.

Ventilation of mass products

Electrostatic perforation has been used since 30 years for ventilation of non filter, RYO or filter cigarettes to create a directed and guided air bypass or Lindstroem principle. For this purpose, cigarette paper for some non filter or RYO cigarettes and almost every kind of filter cigarettes tipping papers are perforated electro statically OFFLINE in zones from 2.0 up to 6.0mm width or in rows with ON-LINE or OFF-LINE by use of slow, fast flow, sealed-off or SLAB CO2 gas or diode laser in order to reduce the harmful substances such as nicotine and condensate down to allowed values. Another effect is the possibility to control the degree of ventilation of Cigarettes.

Online micro perforation – porosity profile

Years ago IPM had developed a multiple online electrostatic micro perforation OESP-1 units at cigarette making machines which was patent applied with EP0460369 and DE4018209.

http://www.freepatentsonline.com/EP0460369.html

The method and the device for electro-erosive perforation of cigarette paper basically operates with at least two pairs of electrodes which are ignited at the same time in such a manner that each perforation section is treated twice in order to provide a corresponding intensity of perforation, taking into consideration the duration of ignition and the web speed. In particular, the invention operates with at least four pairs of electrodes, between which the web of cigarette paper to be perforated is moved through. The cigarette paper is moved in the longitudinal direction of the cigarette to be produced later, the width corresponding to the circumference of the cigarette plus an overlap section for bonding. Perforating is carried out transversely to the direction of movement, that is to say an accurately defined zone section is produced around the circumference of the cigarette. The pairs of electrodes are arranged at a distance which corresponds to half the cigarette length (a, b, c) when four pairs of electrodes are used.

The first and the third pair of electrodes are ignited simultaneously. A distance dependent control causes the second and fourth pair of electrodes also to be ignited simultaneously when the previously perforated sections have traveled the distance of half a cigarette length. Each section is perforated four times, the speed at which the web (10) can be moved being determined not by the spacing (half a cigarette length) of the pairs of electrodes but by the spacing of the pairs of electrodes in each case simultaneously ignited (one cigarette length). This provides for uniform, intensive and very powerful perforation and the cigarette paper treated can be continuously supplied to the cigarette machine for further processing in the longitudinal direction of the cigarette.

That electrostatic micro perforation process enables cigarette or tipping paper while cigarette making processes to reduce nicotine and condensate levels for non-filter and filter cigarettes as well. The OESP-1 devices opens fully new possibilities for cigarette or tipping paper ventilation during cigarette manufacturing by entire perforation cassettes integration into cigarette making machines as Max-S, Protos 80, Protos 90, Mark-9 etc.

Advantages during manufacturing

Compact all-over-dimensions, direct mechanical integration of perforation units, easy functional interfacing and full EMI acceptance in order of EN or NEC standards archiving high production efficiencies with controllable ventilation grades on highly automated cigarette making machines.

• Patented, powerful, dual high frequency switching electronics and multiple perforation performances of the circumference of each cigarette enables problem less perforation on high-speed cigarette making machines up to 12,000 cpm

• Porosity ranges from 50 up up to 400 C.U.
• pore densities from 25 up to 300 pores/cm2
• hole size from 30 up to 80 micron
• cigarette ventilation grades up to 45 % are archive able.
• All necessary perforation, production parameters are stored and controlled by microcomputer operation, i.e. geometrical and synchronized positions of perforation lines, zones etc., pore density, perforation zones width and distributions, perforation profile and porosity ranges for each cigarette brand
• Porosity profiles over the length of each non-filter cigarettes are possible.
• Furthermore single, multiple, different or equal groups of single perforation zones around the circumference of each cigarette for non-filter, RYO even tipping paper for filter cigarettes are possible.
• All stored parameter sets are linked to the PLC system.
• Different micro perforation designs and porosities of each cigarette brand are flexible to define and controllable during all production processes.
• Air ventilation levels are exactly defined and, due to online feedback, can be kept constant by means of perforation system design and porosity distribution.
• For non filter cigarettes for example, perforation can be effected over the entire length and circumference of the cigarette.

Liability and system investment

The ESP process OESP-1 has a high liability and is realizable with low investments and low running costs when compared with online macro or micro laser perforation processes. An online porosity control system OPSS-1 monitor continuously the air permeability, called optical online porovision or porosimeter, with a state-of-the-art technology to obtain a close-loop/feed-back to the perforation unit to keep ventilation grades constant.

Conclusion: Inline micro perforation process is possible to use for other mass products and application fields with full system integration in entire production lines as bag, sack, packaging manufacturing etc.

Technology

ELECTROSTATIC NANO MICRO CLUSTER PERFORATION or material treatment, based at micro discharging and sparking, plasma tunnel effects with gas atomic ionization in nano second time windows. The pores are normally statistical irregularly distributed in controlled size ranges from 0.05-80 microns diameter and analogically, under LASER or MICRO or MACRO PERFORATION, arranged in diameter sizes from 60-200 microns, at best non-inclined holes und holes rows of diverse arrangement comprehension. For the naked human eye invisible electrostatic nano or micro perforations may be arranged in areas or zone bands with specific distances within its web. Controlled pore sizes in wide ranges from 0.050-80 micron diameters by holes sequences up to 16 million pores per second and 0.1-3 mill Joule discharge energy for each pore. Process and power electronics patent granted with DE10328937.

Performance

Arrangements of zones are usually carried out in width from 2 to 6mm and pores density of 15 up to 250 pores per square cm whereas the perforation of areas results in pore densities of up to 5 million pores per m2 in surface-all-over design. Electro static perforations allow porosity levels from 80-2,500 Coresta Units (ml/min/2cm2, 1,000Pa), equality from 40 down to 3 Gurley material web widths from 100-2,000mm at web speeds of up to 500 m/min, depending on porosity and material consistency in relation to its ability to perforate.

Physical Properties

One of the foremost postulation which can be applied to many application purposes and products containing bonded fabrics, bag or packaging papers, non-woven, etc. with gas or steam permeability but water in-permeability will be found at the application stage of the electrostatic nano micro cluster perforation. Which means pore sizes from 0.050-80 microns diameter by up to 5 million per square meter. This is due to the water’s greater surface tension which hampers the permeation through the relatively small nano or micro pores. These and other physical advantages of the relatively small pores necessarily demand the application of the cluster perforation method because alternative perforation or processes are NOT feasible, too expensive or simply uneconomical and would not lead to a successful application.

Introduction

A German-Thai high-tech, engineering company has developed an optical online porosity 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 porosity 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 porosity levels in the same time while the scanner system across the running material web up to 2,000 mm width.Science, R&D, Universities, industrial partners for a licence agreement and / or technical co-operation are sought.

Working principle

The porosity control of natural porous 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 2,000 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 porosity measurement systems for porosity 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 porosity 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 porosities 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 5.0mm. At the same time, the multiple light transmission sensors monitor all porosity profiles and determines envelope curve and calculate the integrals.

Advantages

Thus direct feedback into the perforation system makes it possible to compensate any changes in terms of porosity and perforation locations so that each jumbo production roll up to 25,000 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 porous or perforated web material as cigarette, tipping, plug-wrap, filter, packaging, non-woven, flees, 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.

The former patent application DE19542289 A1 concerns a method and device for optical dynamic, i.e. a non-contact, in-line surface-tension / surface-energy measurement for running substrates whereby the detection can be in the transverse-direction or in the running-direction of the web.

In the context of this invention, running substrates or moved web material is to be especially understood as being plastic films like PE, PP, LLDPE, HDPE, BOPP, LLDPE, EVOH, PTFE, FEP, MOV, PET, PS, PMMA, PBMA, PVC, PA and also laminated or coated film or paper webs which still show a measurable optical transmission in the wavelength range of 1,200 up to 2,200 nm.

A higher material wetting capacity, respectively, a higher material adhesion capacity, which can be achieved by increasing the surface tension, is demanded in many application cases for better printability, coatability or adherence capacity during the manufacture, finishing, printing and processing of running substrate webs.

Described is a method and device for optical dynamic in-line surface-tension measurement in ranges from 30 dynes up to 60 dynes in which a substrate web running vertically through a measuring gap is subjected to a chromatic light transmission from two optical channels displaced by 90° to each other. This light transmission is detectable by two optical detection systems located on the other side of the web.

Material specific wavelength selection, light transmission angle changes, polarisation slot diaphragms and transverse displacements of the light beam feeder along the optical X-axis result in extreme scattering and diffraction of the IR light photons in the boundary layer area on both sides of the sub-nano layer within the substrate web. Their transmitted light intensity enables, after detection and evaluation, the determination of a direct relationship to the absolute surface tension.

And this entirely independent of the material-specific influences like: material and surface consistency, crystallinity, thickness, density, structure, polar grouping, temperature and type of pre-treatment.

Introduction
