Definitions
- the invention relates to a device for producing a rod in the tobacco-processing industry, comprising a supply device, a separating device, a rod-forming device and a
- the supply device is set up to provide a flat web and to feed it to the separating device arranged downstream of the preparation device, the separating device is set up to separate the flat web into a plurality of strips which are arranged downstream of the separating device
- the strand-forming device is set up to form a strand from the plurality of strips and the embossing device is arranged between the supply device and the strand-forming device and is set up to introduce an embossing into the flat web or a plurality of the strips.
- the invention also relates to a method for producing a strand of the tobacco processing industry, comprising the fol lowing steps: providing a flat web with a provision device and feeding the flat web to a downstream downstream of the preparation device, separating the flat web into a plurality of strips with the separating device, forming a strand from the plurality of strips with a strand forming device, embossing the flat web or a plurality of the strips.
- a device for producing a strand in the tobacco processing industry which comprises a separating device with which a flat web is separated into a plurality of individual strips, emerges from DE 1 954 036 A1, for example.
- the flat web is cut into parallel strips with the help of a disk knife cutting device.
- the strips are then combined in a strand and wrapped around them.
- a flat sheet of reconstituted tobacco material is processed.
- the produced and wrapped strand is then cut into segments of a predetermined length, so that rod-shaped articles for the tobacco processing industry can be produced.
- Another device for producing a strand from reconstituted tobacco material is known from DE 10 2018 106 826. This device comprises a separating device which is set up to convert a flat web of reconstituted tobacco material into a
- the strips In the production of tobacco sticks from strips that are cut or separated from reconstituted tobacco material, the strips are shaped into tobacco sticks in a format and then put together and wrapped by means of combining machines.
- the quality of the raw material i.e. the film made from reconstituted tobacco material (also known as “recon film”), fluctuates. This results in fluctuations in the mechanical hardness and the tensile resistance of the manufactured tobacco sticks. Since these two parameters are If important quality parameters are involved, it is desirable to influence them during production, ideally to control them. In this way, unnecessary rejects or even a production stop can be avoided.
- a device for producing a strand of the tobacco processing industry comprising a provision device, a separating device, a strand forming device and an embossing device, wherein
- the provision device is set up to provide a flat track and to feed it to the separating device arranged downstream of the provision device
- the strand-forming device arranged downstream of the cutting device is set up to form a strand from the plurality of strips and
- the embossing device is arranged between the supply device and the strand-forming device and is set up to bring an embossing into the flat web or a plurality of the strips, this device being developed in that the embossing device comprises an adjusting device with which a height of the embossing ver can be changed and at least one sensor unit and a control unit coupled to it are included, the at least one sensor unit being set up to measure at least one physical parameter of the flat web and / or the strand and / or the one produced from the strand.
- th rod-shaped article and the control unit is set up to control and / or regulate a height of the embossing with the adjusting device as a function of the measured physical parameter.
- the embossing made in the flat web or in the majority of the strips is a texturing of the material. Elevations and / or depressions are made in the material, which are of any shape. For example, points, circles, ellipses, knurls, crosses, polygons and combinations of these shapes or even non-uniform shapes can be introduced as the shape of the embossing.
- embossing a three-dimensional shape into the film or the strips the strips present in the strand have a higher filling power. The filling power of the embossed strips is therefore higher compared to non-embossed strips. If the flat web is embossed, this texturing of the flat web is retained when it is separated in the cutting device, i.e. the strips produced are also embossed or textured.
- stacks stack-shaped arrangements
- the strips are therefore, viewed in a cross section of the strand, in a stack on top of one another, their flat sides almost completely touching each other, at least in sections.
- stacks within the strand mean that in the rod-shaped article produced by the tobacco processing industry, not the full surface of the strips can be used.
- the inner surfaces of the strips, which lie directly on top of one another in the stacks, are not accessible to an air flow, for example. These surfaces can therefore only release a very small amount of aroma and active substances into the air flow.
- the stacks have an undesirable influence on the tensile resistance.
- the tensile resistance in an article with a large number of stacks is lower than in an article without a stack.
- the embossing of the flat web advantageously prevents the strips from forming stacks in the strand, that is to say lying against one another over their entire surface at least in sections.
- the embossing of the strips also has the advantage that the strips hook into each other due to the individual elevations and depressions of the embossing. This reduces the probability that individual strips at the head end fall out of the rod-shaped article or are pulled out when the rod-shaped article is in use. The individual strips are therefore more stable in position and there is less fiber displacement. This has advantages not only in terms of the end product, but also in terms of handling the rod-shaped article. Since the rod-shaped articles are often promoted with compressed air in the production process, improved Positionsstabili ity of the individual strips with regard to the achievable quality of the individual rod-shaped articles is advantageous. In other words, the probability is reduced that individual strips, due to the treatment in the production process, will protrude from the front side of the head area of the rod-shaped article.
- the flat web can be reconstituted tobacco material (Recon film). This can be produced by the slurry process or by the paper process.
- the flat web can also be a film, for example a PLA film.
- the flat sheet can be made of paper or cardboard. While rod-shaped HNB articles (HNB stands for heat not burn), for example, can be produced from Recon-Foil, cooling elements, spacer elements or filter elements for or as rod-shaped articles for the tobacco processing industry can be produced from film, paper or cardboard.
- the embossing device comprises an adjusting device with which a height of the embossing can be changed.
- a height of the embossing is a maximum distance between an elevation or a depression from a plane in which the surrounding material of the flat web or of the strip extends. Only the amount of this distance is considered, i.e. no distinction is made between elevation and depression in terms of its height. Changing the height advantageously allows the three-dimensional shape of the strips to be varied. The three-dimensional shape is therefore more pronounced (high height) or less pronounced (low height).
- the device is developed in that the adjusting device is set up to change a pressure applied by the embossing device, in particular by at least one embossing roller, to the flat web or the plurality of strips.
- the change in the pressure applied by the embossing roller (s) to the flat web or the majority of the strips provides a simple control variable with which the height of the embossing and thus, for example, the filling force of the strips can be changed.
- the device comprises at least one sensor unit and a control unit coupled to it.
- the at least one sensor unit is set up to measure at least one physical parameter of the flat web and / or the strand and / or the rod-shaped article produced from the strand.
- the control unit is set up to provide a To control and / or regulate the height of the embossing with the adjusting device as a function of the measured physical parameter.
- the device comprises at least one sensor unit which is designed to measure at least one physical parameter of the flat web of the strand or of the rod-shaped articles produced.
- sensor units can also be provided so that in each case at least one physical parameter at one point, for example on the flat track, or the same parameter, for example the tensile resistance, at several points in the production process, for example on the strand and additionally on the rod-shaped Articles that can be measured. Any combination of these measurements is of course also possible.
- the device according to this embodiment allows a comprehensive process control.
- the device is developed in that the sensor unit is a thickness measuring device which is set up to measure a material thickness of the flat web as a physical parameter of the flat web.
- the device is developed according to a further embodiment in that the sensor unit is set up to measure a mechanical hardness and / or a tensile resistance of the strand and / or the rod-shaped article as physical parameters.
- the thickness measuring device is in particular a non-contact thickness measuring device.
- the material thickness is measured with a light system or an ultrasound system.
- the strand-forming device is also set up to cut the produced strand to length into individual rod-shaped articles, and the sensor unit is for this purpose set up to carry out an individual test on the cut-to-length rod-shaped articles.
- the strength of the embossing can be present as a control and / or regulating parameter in the device, so that a very constant process can be carried out.
- the control of the intensity of the embossing according to one embodiment, the pressure applied by means of the embossing rollers to the flat web or the plurality of strips, can be controlled and / or regulated as it is described, for example, in EP 0242 824 B1.
- the height of a trimmer disc is changed with the help of a servomotor in order to keep the mechanical properties of the cigarettes produced constant.
- the pressure of the embossing rollers can be used in a control or regulation implemented according to the invention.
- Sensor units for determining the mechanical hardness and / or the tensile resistance of the strand are known for example from EP 0284640 B1.
- the embossing is carried out in a termitting manner.
- the embossing device is set up to introduce an intermittent embossing into the flat web or the plurality of strips.
- the flat web is partially in a non-embossed state, in a subsequent section it is in turn in an embossed state.
- These embossed and Non-embossed areas alternate, preferably they alternate regularly.
- the positions of the embossed and non-embossed areas are matched to the position of the strips in the rod-shaped article produced.
- a corresponding position control can be carried out or provided. It is thus advantageously possible to provide rod-shaped articles which comprise embossed strips in certain areas and comprise non-embossed strips in other areas.
- the strips can not be embossed in the area of a head end, so that a heating mandrel, a heating shield or the like can easily be inserted in this area.
- a rod-shaped article is, for example, an HNB article.
- the embossing can also vary along a longitudinal direction of the flat web. This means that the embossing may be weaker in some areas than in others. Here, too, weakly embossed and more strongly embossed areas can alternate, in particular alternate regularly, as before with regard to the non-embossed and embossed areas
- the imprint can also be continuously variable and, for example, follow a periodic function.
- a height of the embossing varies periodically along the direction of the longitudinal extension of the strips.
- rod-shaped articles can be provided which comprise strips whose embossing increases, for example, from the head end in the direction of a mouthpiece.

- the method offers an additional control and / or control parameter, namely the intensity of the embossing. This advantageously makes it possible to run a constant process or to compensate for variations in the starting material through active readjustment of the parameter.
- the method is developed in that a pressure applied by the embossing device, in particular by at least one embossing roller, to the flat web or the plurality of strips is changed with the adjusting device.
- a material thickness of the flat web is measured as a physical parameter with the sensor unit.
- a mechanical hardness and / or a tensile resistance of the strand and / or the rod-shaped article is measured as a physical parameter with the sensor unit.
- individual rod-shaped articles are cut to length with the strand-forming device from the strand produced.
