Description

The invention relates to a method for producing rod-shaped products of the tobacco-processing industry, in particular cigarettes, wherein the bar-shaped products enveloped in each case by a wrapping strip are provided on their wrapping strips with a, in particular linear, perforation pattern of a predetermined number of perforation holes, so that the rod-shaped products, in particular cigarettes, are provided with a predetermined degree of ventilation.

Furthermore, the invention relates to a machine for producing rod-shaped products of the tobacco-processing industry, in particular cigarettes, wherein by means of a perforation Perforationsmuster perforation holes in each of a wrapping strip or wrapping paper and / or tipping paper enveloped rod-shaped products, in particular cigarettes, are introduced.

Furthermore, the invention relates to a system for testing manufactured rod-shaped products of the tobacco processing industry, in particular cigarettes, wherein the rod-shaped products respectively wrapped by a wrapping strip are provided on their wrapping strip with a perforation pattern with a predetermined number of perforation holes respectively.

Under rod-shaped articles or products of the tobacco processing industry are understood in the present context, in particular cigarettes, filter rods, multifilters and tobacco sticks for cigarettes. In particular, rod-shaped products of the tobacco processing industry are understood to mean filter cigarettes, the filter cigarettes each consisting of a filter plug and a tobacco rod which are connected to one another.

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.

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.

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 smoking behavior (taste per puff, number of puffs) as constant as possible, the partial ventilation levels that make up the total degree of ventilation, 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.

When packaging cigarettes on a filter tipping machine, a perforation of holes is made in the fabricated filter cigarettes using perforating means into the wrapping material or the wrapping strips of the bar-shaped articles. 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.

By forming a perforation zone 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 filter end.

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.

In DE 27 50 038 C2 For example, a method of controlling the perforation of cigarettes or other rod-shaped smoking articles is described. To compensate for the tobacco plant ventilation is proposed, the air permeability of the Cigarette paper before stranding or on a separate test drum to be measured before the perforation.

It is also in DE 27 54 104 A1 describes an apparatus for producing a zone of desired air permeability in a wrapping material strip for rod-shaped articles of the tobacco-processing industry.

Furthermore, in DE 41 06 127 A1 discloses a method for perforating shell material of rod-shaped articles of the tobacco processing industry in which the shell material to be perforated is moved through a perforation zone and a corresponding pulsed energetic beam in the perforation zone is aligned with the shell material to form perforation holes on the shell material.

Based on this prior art, the object of the invention is to identify simple and one-to-one produced tobacco industry products in a simple way individually, it should be possible, based on the individual identification of the manufactured products this also in a simple manner identify. Another object of the invention is to increase the anti-counterfeiting security of rod-shaped products of the tobacco processing industry.

The object is achieved by a method for producing rod-shaped products of the tobacco-processing industry, in particular cigarettes or filter cigarettes, wherein the bar-shaped products enveloped in each case by a wrapping strip are provided on their wrapping strips with a perforation pattern of a predetermined number of perforation holes, in particular a linear one in that the rod-shaped products, in particular cigarettes, are provided with a predetermined degree of ventilation, which is further developed in that for a predetermined type of product, in particular cigarette type, with a predetermined degree of ventilation, a first rod-shaped product, preferably a first cigarette, with a first, in particular line-shaped perforation pattern is provided and a second rod-shaped product, in particular second cigarette, is provided with a second perforation pattern, wherein the first perforation pattern the first rod-shaped product differs from the second, in particular linear, perforation pattern of the second rod-shaped product in the arrangement of the perforation holes, wherein in particular the number of perforation holes of the first perforation pattern corresponds to the number of perforation holes of the second perforation pattern and the cumulative total length of the perforation holes of the first perforation pattern the cumulative total length of the perforation holes of the second perforation pattern corresponds.

Under the proviso that the hole width of the perforation holes equal d. H. remains unchanged, it is provided according to the invention that in the formation of the perforation, the number of perforations of the first perforation corresponds to the number of perforations of the second perforation pattern and the cumulative total length of the perforation of the first perforation corresponds to the cumulative total length of the perforation of the second perforation pattern.

The invention is based on the idea that in a filter attachment machine, in which the rod-shaped products, for. As filter cigarettes, are made, the filter cigarettes produced on this machine are formed with a predetermined (total) degree of ventilation. For this purpose, by means of a perforation device, in particular using a laser or a laser beam, a perforation pattern with ventilation holes is introduced into the envelope of the cigarette.

According to the inventive concept, the products or filter cigarettes produced on the production machine are individualized by the mutually distinguishable and different perforation patterns, so that after production at a later time the filter cigarettes produced are identified or authenticated accordingly during a test. For this purpose, the individual perforation pattern of the cigarette is detected individually by means of a type of reader, then the detected, unique, perforation pattern of a cigarette is decoded, for example, so that it is determined on the basis of the detected perforation pattern for each cigarette on which machine this cigarette at a specified time has been produced at a predetermined location. As a result, the security against counterfeiting of manufactured filter cigarettes is significantly increased.

2 shows schematically a filter attachment device 2 in the clipping. Such a filter attachment device or filter attachment machine is under the name "MAX" of HAUNI Maschinenbau. AG, Hamburg, known.

After being made on a (cigarette) stranding machine, the cigarettes become the filter attachment device 2 promoted and handed over to them, where they are connected with filter plug double use length. 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 an example. Stationary counter rolling surface, the cigarettes 7 with axially aligned filter plugs to finished filter cigarettes 100 assembled.

In the production of double filter cigarettes with two outer tobacco rods and arranged inside filter plug twice the length of use, these aforementioned groups are separated from each other by bonding glued pad flakes by cutting centrally, thus forming two webs of queraxial subsidized cigarettes. The cigarettes 100 one lane are subsequently turned and with the cigarettes 100 the other track merged and then demanded in a web transverse axial for further processing.

In order to be able to supply secondary air to the smoke of the filter cigarettes, perforation holes are formed 104a . 104b inserted in the enveloped by a wrapping strip tobacco sticks and / or enclosed by the tipping paper leaflets filter plug using a perforator 16 with a laser 17 , wherein preferably for each web of cross-axially promoted cigarettes a laser 17 is provided.

In 3a In the neckline is a unwound perforated cigarette wrapper strip 110 shown schematically in the prior art, wherein the cigarette wrap strip 110 , by means of which a cigarette is wrapped, at regular intervals in the circumferential direction perforation holes 104 having. The perforation holes 104 are circumferentially formed by means of a perforation device, as described above by way of example, in the cigarette wrapping material strip one behind the other in the circumferential direction. In this case, according to the prior art, the perforation holes 104 a predetermined constant length, wherein also the distance in the circumferential direction between two perforation holes 104 each is kept constant. Due to the formation of equidistantly arranged, equally long perforation holes 104 a predetermined total degree of ventilation of the cigarette is formed.

According to the prior art, the perforation holes 104 in the embodiment according to 3a evenly distributed over the circumference of the cigarettes respectively.

In the 3b . 3c For example, two embodiments of perforated cigarette wrapper strips according to the invention are shown. Here are the cigarette wrapper strips 110 mutually different perforation patterns, wherein the perforation holes 104 irregularly formed and arranged in the circumferential direction. Here are the perforation holes 104 different perforation lengths in the circumferential direction, wherein the distance between two perforation holes 104 is or will vary in the circumferential direction.

The total lengths of the perforation holes 104 in the circumferential direction correspond to the total length of the perforation holes 104 according to the embodiment according to the prior art (see. 3a ), so that even in the embodiments according to the invention in 3b . 3c the cigarettes produced have the same degree of ventilation as a cigarette with a strip of cigarette wrapping material according to 3a (State of the art).

In addition, the number of perforation holes is also 104 in accordance with the embodiments of the invention in 3b . 3c constant. In the embodiments 3b . 3c is the number of perforation holes 104 in the circumferential direction 20 , In 3a are also 20 Perforationslöcher according to the prior art 104 on the cigarette wrapper strip 110 educated.

By varying the length and / or the width or the diameter of the perforation holes 104 in the circumferential direction of a cigarette and the variation of the distances between the perforation holes 104 It is possible for cigarette brands or cigarette types distributed over the cigarette circumference perforation holes 104 arrange so that the arrangement and formation of the perforation holes 104 is company specific and / or brand specific.

As a result, due to the distribution of the perforation holes 104 and the variation of the length or hole length of the perforation holes 104 in the circumferential direction, a predetermined code are applied to the cigarette wrapper strip without changing the overall degree of ventilation for a predetermined product type or cigarette mark.

According to the invention, the irregular distribution of the perforation holes 104 influenced by the extent of the cigarette, whereby also the single length of the perforation holes 104 is influenced, wherein the total length of all perforation holes is kept constant with a constant number of perforation holes over the cigarette circumference.

According to the invention, the hole length and the distribution of the perforation holes are influenced by the perforation of the cigarettes in such a way that an unambiguous assignment based on the individual perforation patterns to a manufacturer and / or production location, production machine and / or production layer is made possible encoded via the production-relevant and characteristic properties of the respective cigarette are introduced into the wrapping strips or cigarette material strips. For example, a perforation may be applied to the cigarette wrapper strip using Morse codes or so-called IAN codes (International Article Number Codes) or EAN codes (European Article Number Codes) or another bar code as a perforation pattern. In the case of a two-lane or multi-lane perforation, a two-dimensional code (2D code) can also be introduced into the tipping paper and / or the wrapping paper as a perforation pattern.

Due to the encrypted codes based on the mutually different perforation patterns, the counterfeit security of the manufactured cigarettes is significantly increased.

Moreover, it is possible within the scope of the invention that in addition to an existing perforation pattern in a first track for a total degree of ventilation of cigarettes additionally an individualizing perforation pattern in a second, preferably parallel, track in the wrapping paper or in the wrapping strip and / or in the tipping paper or be inserted into the tipping paper strips of the cigarettes.

In 4 schematically a system for checking the authenticity of cigarettes is shown. Here, the system has a control system 200 , through the codes to a controller 201 for the production of cigarettes and codes for the control device 202 generated for cigarette packs on a packaging device and to the control devices 201 and 202 be distributed and transmitted accordingly. This produces a one-to-one correspondence of the perforation patterns formed on the cigarettes as a code and a corresponding code on the cigarette packs produced on the packing device.

The control device 201 is with a stranding machine 210 connected, a filter attachment machine 211 and a laser device 212 for perforating the at the Filteransetzeinrichtung 211 manufactured filter cigarettes.

In addition, the control device 201 with an optical test device, the z. B. under the Designation OCIS of the Hauni Maschinenbau AG is connected. In particular, the control device 201 designed for the production of filter cigarettes as a computer device. Furthermore, the control system is also 200 designed as a calculator. The of the control system 200 predetermined perforation patterns applied as a code to the cigarettes are additionally stored in a central data memory 220 stored.
