    description
    FIELD OF THE INVENTION The invention relates to a method for producing cigarettes according to the preamble of claim 1 and to a cigarette machine for implementing the method according to the preamble of claim 11.
    Background Art Cigarette extruding machines have been known in the art for more than 100 years. A cigarette rod maker consists of a distributor unit in which vibrating shaft walls and / or a roller with steel pins ensure a uniform distribution of the cut tobacco arriving through a conveyor belt within the distributor box. At the bottom of the box, the mixed tobacco is pulled apart finely and evenly. This is done by means of an air-permeable, textile conveyor belt (the so-called Saugstrangförderer), which promotes the tobacco from the Verteilerbox evenly. So that the tobacco remains on the belt, a vacuum acts below the air-permeable conveyor belt, so that the tobacco is sucked onto the belt and thus virtually fixed. At the end of the Saugstrangförderers is an excess removal device consisting of two rotating Trimmerscheiben, which remove excess tobacco fibers from the tobacco rod. Depending on the position of the trimmer discs to the conveyor belt, a more or less large amount of tobacco is removed. The tobacco surplus falls into a shaft and is returned to the distribution unit.
    The tobacco rod is then deposited by Saugstrangförderer on a continuously running format tape that forms the tobacco rod round. Then the tobacco rod runs through a narrowed mouthpiece, where the cigarette paper lays around the tobacco rod from the outside. This station is also called a format chamber. At this point is also a glue nozzle with food lime, which glue the cigarette paper on one edge continuously. A short heating section then ensures that the glue can set. In addition, the glue seam is smoothed. This creates an endless, wrapped and taped tobacco rod.
    In an alternative manufacturing method for producing a cigarette, the cut tobacco is singulated in a feeder. The isolated tobacco falls on the bottom of the tobacco sifter on a conveyor belt. The excess tobacco dust is removed in an excess removal device, preferably aspirated. The tobacco is formed on the conveyor belt by a metering wheel to a strand. The tobacco rod is compressed with at least one pressing wheel. Then the tobacco rod is passed through a narrowed mouthpiece and the tobacco rod is wrapped at the mouthpiece with cigarette paper. The cigarette paper is glued along the longitudinal direction of the strand.
    If cigarettes are to be produced which contain, instead of or in addition to the tobacco, a further smokable substance, problems may arise with the processing of this additional substance.
    US 2017/0188 623 A1 describes a process for the production of standardized cannabis cigarettes by means of a commercial cigarette rod maker. The contact points of the machine with the cannabis are greased to prevent the cannabis resin from sticking to the machine. The constant re-greasing of the contact points, however, is labor intensive and prone to error and questionable with regard to food suitability.
    OBJECT OF THE INVENTION From the disadvantages of the described prior art, the object which initiates the present invention is to propose a method for the production of cigarettes, which makes it possible to produce cigarettes which, in addition to the tobacco, contain a smokable additional substance without the Additional substance affected the manufacturing process or an uneven distribution of the additive substance would be present in the cigarettes.
    The solution of the problem is achieved in a method for the production of cigarettes characterized in that the tobacco rod after the strand forming and before the mouthpiece a smokable additive substance is added. The choice of the place of addition allows that in the cigarette machine additives can be processed, which would usually pollute the cigarette machine so strong that they are difficult or impossible to process. These include, for example, resinous plants whose resin sticks the parts of the cigarette machine with which the plants come into contact. Obviously, it would be to mix the additive with the tobacco before the mixture of the cigarette machine is abandoned in order to achieve a homogeneous mixture between the additive and the tobacco. In this case, however, a maximum number of parts of the cigarette machine come into contact with the additive and almost the entire cigarette machine is contaminated. In particular, the tobacco deduction, the conveyor belt and the role that separates the tobacco is contaminated and can no longer fulfill their task of tobacco separation satisfying.
    Another place of metering the expert does not consider, since the additive after the strand formation of the tobacco can not be uniformly mixed with the additive without the strand is destroyed.
    Surprisingly, among other things, the inevitably occurring vibrations in the cigarette machine to the fact that the additional substance in the tobacco rod distributed homogeneously, even if the additive substance is supplied to the already formed tobacco rod.
    Another advantage is that during the suction of the tobacco dust no hemp is sucked with, since the hemp is supplied to the tobacco rod only after the extraction of tobacco dust.
    The invention is preferably characterized in that the tobacco rod is mixed with the smokable additive immediately prior to compression. As a result, the additive is added to the tobacco just before the tobacco rod is wrapped in cigarette paper. Therefore come as few parts of the device with the polluting additive in contact. Preferably, the compression of the tobacco rod is made by a press wheel which presses from above onto the tobacco rod. It would also be conceivable to distribute the additional substance to the press wheel on the tobacco rod, ie immediately before the tobacco rod is wrapped in cigarette paper.
    As appropriate, it has been found that the compression of the tobacco rod is done with at least one press wheel. The press wheel not only compresses the tobacco, but also presses the previously placed on the tobacco rod additive substance to the tobacco rod. The pressing wheel can be easily cleaned if the additional substance, especially if it is resinous, adheres to this.
    In a particularly preferred embodiment of the invention, the smokable additive substance is added to the tobacco rod with a vibrating conveyor. The vibratory conveyor is a very robust reliable conveyor, which allows accurate metering of the additive.
    Conveniently, the vibratory conveyor comprises a conveyor which is vibrated, whereby the additive substance is conveyed in the direction of the tobacco rod. The delivery rate of the additional substance can be adjusted precisely by the amplitude width and the frequency of the oscillation.
    In a further preferred embodiment of the invention, the delivery rate of the additional substance, which is added to the vibratory conveyor, depending on the flow rate of the tobacco rod. Thereby, the ratio of the amount of the additive substance to the amount of the tobacco can be kept constant, regardless of the production speed with which the cigarette machine is running.
    The invention is also preferably characterized by the fact that the additional substance is finer crushed than the tobacco. This degree of comminution makes it easier for the additional substance applied to the tobacco rod to penetrate into the tobacco rod by means of vibrations and to distribute itself homogeneously there. Even during the transport of the cigarettes to the outlets, vibrations occur which evenly distribute the additive in the tobacco rod.
    In a further particularly preferred embodiment of the invention comminuted components of the hemp plant are used as an additional substance. Although hemp contains resin and oil that sticks to the parts of the cigarette machine that touch it, hemp can be processed as an additive. According to the method, the hemp is fed into the process as late as possible in order to glue as few machine parts as possible. In any case, the hemp is fed to the tobacco rod after the extraction of the excess tobacco or tobacco dust, so that it is not sucked together with the tobacco excess. Also conceivable are other smokable additional substances, such as herbs or cloves, which give the cigarette smoke a specific flavor.
    Conveniently, the ingredients of the hemp plant are cut for comminution. In this way, the degree of comminution can be set precisely; in particular, the degree of comminution of the hemp plant can be adjusted so that the hemp parts can penetrate well into the tobacco rod and combine homogeneously with it.
    In a further particularly preferred embodiment of the invention, the additive substance is applied to the top of the tobacco rod and distributed by vibrations which occur during the production process of the cigarettes evenly in the tobacco rod. Pre-mixing of the additive substance with the tobacco, which takes place before the mixture is fed to the cigarette machine, can therefore be dispensed with.
    Another aspect of the invention relates to a cigarette machine for implementing the method described above, comprising a metering device, which is arranged between the strand former and the mouthpiece and can give up a smokable additive substance on top of the tobacco rod. The positioning of the metering device makes it possible that no additional substance is sucked off with the excess removal device and as few parts of the cigarette machine come into contact with the additional substance.
    In a particularly preferred embodiment of the invention, the metering device is arranged in the conveying direction of the tobacco rod immediately before the compression device. As a result, the additional substance is added to the tobacco rod before it is compressed and can be distributed in this. In addition, the compression device pushes the additive into the tobacco rod and only the compression device and the mouthpiece come into contact with the additive substance.
    Conveniently, the strand former is realized by a metering wheel. The dosing reliably forms a closed homogeneous strand of the isolated tobacco.
    Conveniently, the compression device is realized by at least one press wheel. The contact pressure can be adjusted by the distance between the press wheel and the conveyor belt and the press wheel can be easily cleaned if it is contaminated by the additional substance.
    It proves to be advantageous if the metering unit is a vibratory conveyor. The vibratory conveyor is robust and requires little maintenance. In addition, the delivery rate of the additional substance can be precisely metered.
    Further advantages and features will become apparent from the following description of an embodiment of the invention with reference to the schematic representations. It shows in not to scale representation:
    Fig. 1: Schematic diagram of a cigarette machine to explain the method for the production of cigarettes.
    In Fig. 1, a cigarette machine is shown, which is designated overall by the reference numeral 11. The cigarette machine can also be referred to as a cigarette rod maker. The method makes it possible to produce cigarettes in a simple manner, which contain a smokable additive substance 13 in addition to tobacco.
    The cigarette machine 11 comprises a tobacco separator 14 which separates cut tobacco 16. The cut tobacco 16 is guided over a rotating roller 15 for its separation. The roller 15 pulls the cut tobacco 16 evenly apart and the tobacco falls from the bottom of the roller 15 on a first conveyor belt 17th
    Excess tobacco dust is removed from the tobacco 16 by an excess removal device 23. Preferably, the tobacco dust is sucked off. After the tobacco dust has been extracted, the tobacco 16 is fed to a strand former in the form of a metering wheel 19. The dosing 19 pulls a certain amount of tobacco from the first conveyor belt 17 and puts the tobacco, formed as a strand 20 on a second conveyor belt 21.
    On the top of the tobacco rod 20 formed a smokable additive substance 13 is metered. The additional substance 13 is preferably made of crushed plant parts of the hemp plant. For example, this may be the flowers and / or leaves of the hemp plant. Preferably, the degree of comminution of the additional substance 13 is greater than the degree of comminution of the tobacco. The additive substance 13 is therefore finer in size than the tobacco. As a result, the additional substance 13 can be homogeneously distributed in the tobacco rod 20.
    The tobacco rod 20 is compressed with at least one press wheel 25 before it is wrapped in a mouthpiece (not shown in FIG. 1) with cigarette paper. The additional substance 13 is preferably metered into the tobacco rod 20 immediately before the pressing wheel 25 and pressed onto the tobacco rod 20 by the pressing wheel 25. Usually, an additive substance 13 is mixed with the tobacco before it is processed in the cigarette machine 11. If the additive substance 13 contains resin like hemp, the entire cigarette machine 11 is adhered to the resin. Sites that come into contact with the hemp must be greased as described above, so that the cigarette machine is not clogged and constantly cleaned.
    The inventive method takes a completely different route: Although the skilled person believes that the additional substance 13 must be mixed as well as possible with the tobacco in order to be evenly distributed in the tobacco rod 20, according to the present method, the additional substance 13 just before the compression of the tobacco rod 20 this metered. In addition, the additive substance 13 is given up only at the top of the strand. Surprisingly, the additive substance 13 does not remain inhomogeneously distributed in the cigarette rod and the cigarettes produced therefrom. Rather, the additional substance 13 is homogeneously distributed in the tobacco rod 20 by the shocks and vibrations which inevitably act on the tobacco rod 20 and the cigarettes produced therefrom during the production process. The additional substance 13 can therefore be metered in without the cigarette machine being contaminated by it. The only machine part, which comes into contact with the additive substance 13, is the compression device in the form of the press wheel (s) 25. The press wheel 25 is easy to clean if the additive substance 13 should pollute it to such an extent that the dirt is the function of the Press wheel 25 impaired.
    The additional substance 13 is added to the tobacco rod 20 by a vibratory conveyor 27. The vibratory conveyor 27 comprises a storage container with metering flap 29 and a conveyor trough 31. The reservoir 29 and the conveyor trough 31 are set in vibration by a vibratory drive. As a result, the additional substance 13 located in the storage container 29 is added to the tobacco rod 20 via the conveyor trough. The delivery rate of the additional substance 13 can be adjusted by the oscillating drive to the delivery rate of the tobacco or of the tobacco rod 20. As a result, a quantitative ratio between the tobacco and the additional substance 13 can be set precisely. The oscillating drive may also be dependent on the flow rate of the tobacco, so that the proportions between the tobacco and the additive substance 13 remain constant when the flow rate of the tobacco in the cigarette machine 11 is changed. After compression of the tobacco rod 20 and the additive substance 13 with the press wheel 25, the tobacco potion 20 is guided with the additional substance 13 in a known manner through a mouthpiece and wrapped with cigarette paper.
    The method described makes it possible to produce cigarettes which are mixed with an additional substance 13, without the additive substance 13 contaminating the cigarette machine 11. As a result, resin-containing additional substances, for example comminuted components of the hemp plant, can be used without the resin sticking the cigarette machine 11. Another advantage is that during the extraction of excess tobacco no hemp is sucked with, since the hemp is fed to the tobacco rod only after the suction.
