Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Filterzigaretten, wobei die Filterzigaretten jeweils von einem Umhüllungsmaterial umhüllt sind wobei unter Verwendung einer ersten Perforationseinrichtung ein in Umfangsrichtung der jeweiligen Filterzigaretten umlaufendes erstes Perforationsmuster mit Perforationslöchern erzeugt wird und unter Verwendung einer zweiten Perforationseinrichtung neben den in Umfangsrichtung der jeweiligen Filterzigaretten auszubildenden oder ausgebildeten ersten Perforationsmuster in wenigstens einem Umfangszonenabschnitt des Umhüllungsmaterials der Filterzigaretten ein zweites Perforationsmuster mit wenigstens einem oder mehreren Perforationslöchern zusätzlich erzeugt wird.The invention relates to a method for producing filter cigarettes, wherein the filter cigarettes are each enveloped by a wrapping material using a first perforation means in the circumferential direction of the respective filter cigarettes revolving first perforation pattern is generated with perforations and using a second perforating next to the circumferential direction of the respective Filter cigarettes trainees or trained first perforation in at least one peripheral zone portion of the wrapping material of the filter cigarettes, a second perforation pattern is additionally generated with at least one or more perforation holes.

Ferner betrifft die Erfindung eine Vorrichtung zum Herstellen von Filterzigaretten, wobei die Filterzigaretten jeweils von einem Umhüllungsmaterial umhüllt sind.Furthermore, the invention relates to an apparatus for producing Filter cigarettes, wherein the filter cigarettes are each covered by a wrapping material.

Bei der Herstellung von Zigaretten, insbesondere Filterzigaretten, werden im Bereich der Filter Nebenluftkanäle in Form von Löchern oder Perforationslöchern eingebracht, durch die beim Ziehen an den Zigaretten dem Rauch Nebenluft zugeführt wird. Es wird dabei angestrebt, einen relativ großen Nebenluftstrom zuzuführen, der in einem vorgegebenen, möglichst konstanten Verhältnis zu dem die Zigaretten verlassenden Gesamtstrom stehen soll. Dieses Verhältnis wird mit Gesamtventilationsgrad bezeichnet. Es ist bereits bekannt, Zigaretten mit Löchern zu versehen, d. h. sie zu perforieren, z. B. durch Entlangrollen an einer mit Nadeln besetzten Rollfläche.In the production of cigarettes, in particular filter cigarettes, secondary air ducts in the form of holes or perforation holes are introduced in the region of the filter, through which the smoke is supplied to secondary air when pulling on the cigarettes. It is aimed at supplying a relatively large secondary air flow, which should be in a predetermined, as constant as possible ratio to the cigarettes leaving the total flow. This ratio is referred to as the total degree of ventilation. It is already known to provide cigarettes with holes, d. H. to perforate them, z. B. by rolling along an occupied with needles rolling surface.

Es ist auch bekannt, Zigaretten mittels Laserstrahlen zu perforieren, wobei jeweils eine bestimmte Anzahl von Löchern mit einem gewünschten Gesamtquerschnitt aufgebracht wird.It is also known to perforate cigarettes by means of laser beams, wherein in each case a certain number of holes with a desired overall cross-section is applied.

Um die Zigaretten einer Marke hinsichtlich Kondensat, Nicotin und Kohlenmonoxid (CO) im Rauch einerseits, andererseits hinsichtlich des vom Raucher registrierten Verhaltens beim Rauchen (Geschmack pro Zug, Zugzahl und Zugwiderstand) möglichst konstant zu halten, müssen die Teilventilationsgrade, aus denen sich der Gesamtventilationsgrad zusammensetzt, möglichst konstant sein. Dieser Gesamtventilationsgrad setzt sich aus Filterventilationsgrad und Tabakstockventilationsgrad zusammen, wobei diese innerhalb vorgegebener Toleranzen liegen müssen.In order to keep the cigarettes of a brand with regard to condensate, nicotine and carbon monoxide (CO) in the smoke on the one hand, and on the other hand with regard to the smoker's registered behavior during smoking (taste per train, train number and draw resistance) as constant as possible, the partial ventilation levels, which make up the total Ventilationsgrad composed, be as constant as possible. This total degree of ventilation is made up of the degree of filter ventilation and the level of tobacco smoke ventilation, which must be within specified tolerances.

Bei der Konfektionierung von Zigaretten an einer Filteransetzmaschine wird bei den hergestellten Filterzigaretten unter Verwendung einer Perforationseinrichtung eine Perforation aus Löchern in das Hüllmaterial oder die Umhüllungsstreifen der stabförmigen Artikel eingebracht. Insbesondere wird dabei eine gleichmäßige Perforation in die Umhüllungsstreifen eingebracht, wodurch die Umhüllungsstreifen eine vorbestimmte, gewünschte Luftdurchlässigkeit beim Rauchen aufweisen, so dass aufgrund des eingebrachten Perforationsmusters in die Umhüllungsstreifen Nebenluft angesaugt wird, mit der Anteile von Nikotin und Kondensat im Rauch beeinflusst werden. Insbesondere wird die Perforation in die Umhüllungsstreifen unter Verwendung von Laserstrahlen als kohärente Strahlung eingebracht, wodurch sich eine sehr genaue konstante Zone gewünschter Luftdurchlässigkeit in der Umhüllung der Rauchartikel ergibt.When packaging cigarettes on a filter tipping machine, in the manufactured filter cigarettes using a perforating device, a perforation of holes is made in the wrapping material or the wrapping strips of the bar-shaped articles brought in. In particular, a uniform perforation is thereby introduced into the wrapping strips, whereby the wrapping strips have a predetermined, desired air permeability during smoking, so that secondary air is sucked into the wrapping strips due to the perforation pattern introduced, with which the proportions of nicotine and condensate in the smoke are influenced. In particular, the perforation is introduced into the wrapping strips using laser beams as coherent radiation, resulting in a very accurate constant zone of desired air permeability in the wrapping of the smoking articles.

Durch das Ausbilden von Perforationen in dem Hüllmaterial der stabförmigen Artikel wird die Umhüllung mit einer Zone einer vorbestimmten Luftdurchlässigkeit versehen, um dem Rauch bei jedem Zug einer Zigarette eine bestimmte Menge an Frischluft beizumischen. Das Hüllmaterial oder die Umhüllungsstreifen dieser Artikel bestehen in der Regel aus Papier, wobei das Hüllmaterial oder die Umhüllungsstreifen zum Erzeugen einer gewünschten Luftdurchlässigkeit in vorgegebenen Abständen perforiert werden. Bei Filterzigaretten ist es allgemein üblich, die Perforationen im Belagpapierblättchen am mundstückseitigen Filterende vorzunehmen.By forming perforations in the wrapping material of the rod-shaped articles, the wrapping is provided with a zone of predetermined air permeability to add a certain amount of fresh air to the smoke each time a cigarette is pulled. The wrapping material or wrapper strips of these articles are typically made of paper, whereby the wrapping material or wrapper strips are perforated at predetermined intervals to produce a desired air permeability. For filter cigarettes, it is common practice to make the perforations in the tipping paper leaflet at the mouthpiece side filter end.

Das Versehen von Rauchartikeln mit einer Zone gewünschter Luftdurchlässigkeit im Bereich des Mundstückendes, einer so genannten Ventilationszone, werden die Artikel mit einem vorbestimmten (Gesamt-)Ventilationsgrad bereitgestellt, um vorgegebene Werte für Nikotin und Kondensat im Rauch eines Rauchartikels oder einer Filterzigarette mit einer solchen Zone gewünschter Luftdurchlässigkeit einhalten zu können.The provision of articles of smoking with a zone of desired air permeability in the region of the mouthpiece end, a so-called ventilation zone, provides the articles with a predetermined (total) degree of ventilation to preset levels of nicotine and condensate in the smoke of a smoking article or filter cigarette with such zone to be able to comply with the desired air permeability.

Durch Rollen an einer bspw. stationären Gegenrollfläche werden die Filterzigaretten 100 mit axial fluchtend angelegten Filterstopfen zu fertigen Filterzigaretten 100 konfektioniert.After being manufactured on a (cigarette) stranding machine, the tobacco rods of double useful length are conveyed to the filter attachment device 2 and transferred to it, cut there into simple use length and spaced apart and connected with filter plugs of double use length inserted therebetween. For this purpose, the filter plug also a tipping paper strip is fed, which deducted from a tipping paper roll or reel, glued and sliced in leaflets, which are called on tipping paper leaflets. By rolling on a stationary counter rolling surface, for example, the filter cigarettes 100 are assembled into filter cigarettes 100 with axially aligned filter plugs.

Bei Herstellung von Doppelfilterzigaretten mit zwei außen liegenden Tabakstöcken und innen angeordnetem Filterstopfen doppelter Gebrauchslänge werden diese vorgenannten Gruppen nach dem Verbinden durch beleimte Belagblättchen durch mittiges Schneiden voneinander getrennt, womit sich zwei Bahnen queraxial geförderter Zigaretten bilden. Die Filterzigaretten 100 der einen Bahn werden nachfolgend gewendet und mit den Filterzigaretten 100 der anderen Bahn zusammengeführt und sodann in eine Bahn queraxial zur Weiterverarbeitung abgefördert.When producing double-filter cigarettes with two outer tobacco rods and filter plug of double use length arranged inside, these above-mentioned groups are after being joined by glued cover sheets by means of central cutting separated from each other, thus forming two webs of cross-promoted cigarettes. The filter cigarettes 100 of one web are subsequently turned over and merged with the filter cigarettes 100 of the other web and then conveyed away into a web transversely for further processing.

Um dem Rauch der Filterzigaretten Nebenluft zuführen zu können, werden Perforationslöcher 104 eines ersten Perforationsmusters in die von einem Umhüllungsstreifen umhüllten Tabakstöcke und/oder von dem Belagpapierblättchen umhüllten Filterstopfen eingefügt unter Verwendung einer ersten Perforationsvorrichtung 16.1 mit einem ersten Laser 17.1, wobei vorzugsweise für jede Bahn von queraxial geförderten Zigaretten ein Laser 17.1 vorgesehen ist.In order to be able to supply secondary air to the smoke of the filter cigarettes, perforation holes 104 of a first perforation pattern are inserted into the filter sticks enveloped by a wrapping strip and / or filter pads enveloped by the covering paper leaflet using a first perforating device 16.1 with a first laser 17.1, preferably for each web of transversely promoted cigarettes a laser 17.1 is provided.

Ein von einem ersten steuerbaren Laser 17.1 ausgehender Laserstrahl 18.1 gelangt über Spiegel 19.a und 19.b sowie eine Linse 21.1 auf den Filter 8, so dass unter Verwendung des gepulst gesteuerten Laserstrahls 18.1 des Lasers 17.1 Perforationslöcher 104 des ersten Perforationsmusters durch den Belagpapierstreifen der Filterzigaretten 100 gebrannt werden, so dass beim Ziehen an der Filterzigarette 100 kühle Nebenluft durch die Perforationslöcher 104 des ersten Perforationsmusters in den Filter 8 und/oder Tabakstock 101 eintreten kann, wo sie sich mit dem durch die Filterzigarette 100 strömenden Rauchstrom vermischt.A laser beam 18.1 emanating from a first controllable laser 17.1 passes through the mirrors 19.a and 19.b as well as a lens 21.1 onto the filter 8, so that perforation holes 104 of the first perforation pattern are produced by the covering paper strip using the pulsed laser beam 18.1 of the laser 17.1 Filter cigarettes 100 are fired so that when pulling on the filter cigarette 100 cool secondary air can enter through the perforation holes 104 of the first perforation in the filter 8 and / or tobacco stick 101, where they mix with the flowing through the filter cigarette 100 smoke flow.

Ferner werden unter Verwendung einer zweiten Perforationsvorrichtung 16.2 mit einem zweiten Laser 17.2 die Perforationslöcher 105 des zweiten Perforationsmusters 5 in vorbestimmten kleinen Umfangszonenabschnitten des Belagpapierstreifens 9 erzeugt. Hierbei wird der vom steuerbaren zweiten Laser 17.2 ausgehende Laserstrahl 18.2 über Spiegel 19.c und 19.d sowie eine Linse 21.2 auf die Oberfläche der zu perforierenden Filterzigarette 100 geführt, so dass durch die unabhängige Steuerung der beiden separaten Laser 17.1, 17.2 die beiden Perforationsmuster 4, 5 (vgl. Fig. 1) unabhängig voneinander erzeugt werden. Hierbei wird der erste Laser 17.1 im regelmäßig mit gleichen Zeitintervallen gepulsten und im sogenannten Standard-Modus betrieben, während der zweite Laser 17.2 an vorbestimmten Stellen des Umfangs der Filterzigarette 100 mittels einer vorbestimmten Pulsfolge den Belagpapierstreifen 9 abschnittsweise perforiert. Durch die Steuerung des zweiten Lasers 17.2 werden vorzugsweise zwei diametral gegenüber am Umfang der Filterzigarette 100 ausgebildeten Zonen mit dem zweiten Perforationsmuster 5 ausgebildet.Further, using a second perforating device 16.2 with a second laser 17.2, the perforation holes 105 of the second perforation pattern 5 are formed in predetermined small peripheral zone portions of the tipping paper strip 9. In this case, the laser beam 18.2 emanating from the controllable second laser 17.2 is guided via mirrors 19.c and 19.d as well as a lens 21.2 onto the surface of the filter cigarette 100 to be perforated that the two perforation patterns 4, 5 (cf. Fig. 1 ) are generated independently of each other. Here, the first laser 17.1 is regularly pulsed at the same time intervals and operated in the so-called standard mode, while the second laser 17.2 at predetermined locations of the circumference of the filter cigarette 100 by means of a predetermined pulse sequence the tipping paper strip 9 perforated sections. By controlling the second laser 17. 2, two zones formed diametrically opposite the periphery of the filter cigarette 100 are preferably formed with the second perforation pattern 5.
