Abstract
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Herstellen von Zigaretten oder anderen rauchbaren Produkten, bei dem ein Tabakstrang (15) von einem Hüllmaterialstreifen (17) umhüllt und mit einer vorbestimmten Geschwindigkeit an einer Laser-Schneideinheit (23, 33, 36, 39) vorbeibewegt wird, wobei die Laser-Schneideinheit (23, 33, 36, 39) den umhüllten Tabakstrang (19) in einzelne stabförmige Abschnitte (24) trennt. Der umhüllte Tabakstrang (19) wird mit ultrakurz gepulstem, hochenergetischen Laserlicht eines Femtosekundenlasers (22) geschnitten, wobei das vom Laserlicht beaufschlagte Material (11, 17) zum Großteil nahezu ohne Schmelzvorgang von der festen in die gasförmige Phase übergeht.The invention relates to a method and an apparatus for producing cigarettes or other smokable products, in which a tobacco rod (15) is enveloped by a wrapping material strip (17) and pressed at a predetermined speed on a laser cutting unit (23, 33, 36, 39). is passed, wherein the laser cutting unit (23, 33, 36, 39) the wrapped tobacco rod (19) into individual rod-shaped sections (24) separates. The wrapped tobacco rod (19) is cut with ultrashort pulsed, high-energy laser light of a femtosecond laser (22), wherein the material acted upon by the laser light (11, 17) for the most part passes almost without melting from the solid to the gaseous phase.
Description
Die Erfindung betrifft ein Verfahren zum Herstellen von Zigaretten oder anderen rauchbaren Produkten, bei dem ein Tabakstrang von einem Hüllmaterialstreifen umhüllt und mit einer vorbestimmten Geschwindigkeit an einer Laser-Schneideinheit vorbeibewegt wird, wobei die Laser-Schneideinheit den umhüllten Tabakstrang in einzelne stabförmige Abschnitte trennt. Die Erfindung betrifft des Weiteren eine Vorrichtung zur Durchführung des Verfahrens.The The invention relates to a method for producing cigarettes or Other smokable products that have a tobacco rod from one wrapping material wrapped and passing a laser cutting unit at a predetermined speed is, wherein the laser cutting unit the wrapped tobacco rod into individual rod-shaped Sections separates. The invention further relates to a device to carry out of the procedure.
Die
Prozessgeschwindigkeit heutiger Maschinen zur Herstellung von Zigaretten
ist äußerst hoch.
Aus diesen hohen Geschwindigkeiten resultiert das Problem starker
Abnutzung der eingesetzten Komponenten. Insbesondere metallische
Schneidmesser, die den endlosen, mit Zigarettenpapier umhüllten Tabakstrang
in die einzelnen stabförmigen Abschnitte
trennen, die die Länge
einer Zigarette oder Vielfache davon aufweisen, unterliegen einem starken
Verschleiß.
In der
Nachteilig bei dem dort offenbarten Schneidverfahren ist allerdings, dass beim Schneidvorgang in den Materialien störende, thermisch bedingte Prozesse aktiviert werden. Der thermische Eintrag in das Material ist so groß, dass es insbe sondere zu einem Abbrand des umhüllenden Papiers, des Tabaks und der dem Tabak hinzugegebenen Beimischungen kommen kann. Ungewollte Geschmacksveränderungen der fertiggestellten Zigaretten können die Folge sein. Darüber hinaus können bei dem Schneidprozess unangenehme Gerüche entstehen.adversely in the cutting method disclosed therein, however, that at Cutting process in the materials disturbing, thermally induced processes to be activated. The thermal entry into the material is like this large, that in particular special to a burning of the enveloping paper, the tobacco and the admixtures added to the tobacco may come. unwanted changes in taste The finished cigarettes can be the result. Furthermore can unpleasant odors develop during the cutting process.
Aufgabe der vorliegenden Erfindung ist es daher, das eingangs genannte Zigarettenherstellungsverfahren und die Vorrichtung dahingehend zu verbessern, dass ein schnelles und genaues Schneiden des umhüllten Tabakstranges möglich ist, wobei ein Abbrennen des Hüllmaterials, des Tabaks oder der Tabakbeimischungen sowie das Auftreten von unangenehmen Gerüchen deutlich reduziert oder vermieden wird.task It is therefore the object of the present invention to provide the above-mentioned cigarette manufacturing process and to improve the device so that a fast and precisely cutting the wrapped one Tobacco strings possible is, whereby a burning off of the wrapping material, of tobacco or tobacco admixtures as well as the appearance of unpleasant ones smells significantly reduced or avoided.
Diese Aufgabe wird gelöst durch ein Verfahren der eingangs genannten Art zum Herstellen von Zigaretten oder anderen rauchbaren Produkten, bei dem der umhüllte Tabakstrang mit ultra-kurz gepulstem, hochenergetischem Laserlicht eines Femtosekundenlasers geschnitten wird.These Task is solved by a method of the type mentioned above for the manufacture of cigarettes or other smokable products where the wrapped tobacco rod is with ultra-short pulsed, high-energy laser light of a femtosecond laser is cut.
Durch den Einsatz eines Femtosekundenlasers wird erreicht, dass das vom Laserlicht beaufschlagte Material nahezu ohne Schmelzvorgang von der festen in die gasförmige Phase übergeht. Die äußerst kurze Pulsdauer eines Femtosekundenlasers, die vorzugsweise im Bereich von 10 bis 10.000 fs (1 fs = 10–5 s) liegt, führt dazu, dass der Laser in dem durch den Laserstrahl beaufschlagten Material Sublimationsprozesse initiiert. Der Abbrand von Papier, Tabak und Tabakbeimischungen wird vermieden.The use of a femtosecond laser ensures that the material acted upon by the laser light passes from the solid to the gaseous phase almost without melting. The extremely short pulse duration of a femtosecond laser, which is preferably in the range of 10 to 10,000 fs (1 fs = 10 -5 s), causes the laser in the material acted upon by the laser beam initiated sublimation processes. The burning off of paper, tobacco and Tabakbeimischungen is avoided.
Vorzugsweise wird ein Femtosekundenlaser eingesetzt, der Laserlicht einer Wellenlänge aussendet, die im Bereich von 350 bis 450 nm liegt, insbesondere im Bereich um ca. 390 nm – 410 nm. In diesem Wellenlängenbereich absorbiert, wie Messungen ergeben haben, Tabak das eingestrahlte Licht besonders stark, so dass die einzelnen Lichtpulse zu einem optimalen Energieeintrag führen.Preferably a femtosecond laser is used, which emits laser light of one wavelength, which is in the range of 350 to 450 nm, especially in the range around 390 nm - 410 nm. In this wavelength range As measurements have shown, tobacco absorbs the irradiated Light particularly strong, so that the individual light pulses to a lead to optimal energy input.
Weitere Merkmale der Erfindung, insbesondere bezogen auf die Führung bzw. Lenkung des Laserstrahls mittels geeigneter Ablenksysteme, ergeben sich aus den beigefügten Unteransprüchen, der nachfolgenden Beschreibung konkreter Ausführungsbeispiele sowie den Zeichnungen.
