Definitions

  • the invention relates to a device for producing a strand in the tobacco processing industry, comprising a supply device, a separating device, a strand forming device and an embossing device, the supply device being set up to provide a flat web and to feed it to the separating device arranged downstream of the supply device, the separating device being set up for this purpose is to separate the flat web into a plurality of strips, the strand forming device arranged downstream of the separating 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 be in the flat web or a The majority of the strips are embossed.
  • the invention further relates to a method for producing a strand for the tobacco processing industry, comprising the following steps: providing a flat web with a supply device and feeding the flat web to a downstream the separating device arranged in the supply 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 strips.
  • a device for producing a strand in the tobacco processing industry which includes a separating device with which a flat web is separated into a large number of individual strips, is used DE 1 954 036 A1 out.
  • the flat sheet is cut into parallel strips using a disk knife cutting device.
  • the strips are then combined into a strand and surrounded with a covering.
  • a flat sheet of reconstituted tobacco material is processed.
  • the produced and coated strand is then cut into segments of predetermined length so that rod-shaped articles for the tobacco processing industry can be produced.
  • Another device for producing a strand of reconstituted tobacco material is available DE 10 2018 106 826 known.
  • This device comprises a separating device which is set up to separate a flat web of reconstituted tobacco material into a plurality of strips by using a separating device to separate immediately adjacent strips from one another along a predetermined dividing line in the effective area by stretching the flat web to such an extent transversely to the dividing line will cause it to tear apart along the dividing line.
  • a device for producing a strand of reconstituted tobacco material is known.
  • a flat web of reconstituted tobacco material is separated into a plurality of parallel strips using a cutting device.
  • the device includes a pair of transversely toothed rollers with which a transverse crimp is introduced into the flat web.
  • the machine is set up to measure the mass supplied in a production process to regulate reconstituted tobacco material. This is done by using a roll cutter to continuously remove part of the material web from the process, whereby the mass of the material fed into the production process is controlled by the mass of the material web that is discharged.
  • a width of the discharged material web is varied.
  • the strips When producing tobacco sticks from strips that are cut or separated from reconstituted tobacco material, the strips are formed into tobacco sticks in a format and then placed together and wrapped using combining machines.
  • the quality of the starting material i.e. the film made from reconstituted tobacco material (also known as “recon film”), varies. This results in fluctuations in the mechanical hardness and tensile resistance of the tobacco sticks produced. Since these two parameters are important quality parameters, it is desirable to influence them during production, ideally to control them. So can Unnecessary waste or even a production stop can be avoided.
  • the embossing introduced into the flat web or into the majority of the strips is a texturing of the material. Elevations and/or depressions are made into the material, which can have any shape. For example, dots, circles, ellipses, knurls, crosses, polygons and combinations of these shapes or even uneven shapes can be introduced as a form of embossing.
  • 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 separating device, i.e. the strips produced are also embossed or textured.
  • stacks stack-shaped arrangements
  • the strips When viewed in a cross section of the strand, the strips lie in a stack one above the other, their flat sides touching almost the entire surface, at least in sections.
  • stacks within the strand mean that the full surface of the strips cannot be used in the rod-shaped article produced by the tobacco processing industry.
  • 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 aromas and active ingredients into the air flow to a very small extent.
  • the stacks have an undesirable influence on the tensile resistance. For constant mass within the rod-shaped article, the tensile resistance in an article with a large number of stacks is lower than in an article without stacks.
  • the embossing of the flat web advantageously prevents the stripes from getting stuck Form a strand stack, i.e. lie against each other over the entire surface at least in sections.
  • the technical disadvantages outlined above can be reduced or completely avoided.
  • the embossing of the strips also has the advantage that the strips interlock with each other due to the individual elevations and depressions of the embossing. This reduces the likelihood that individual strips at the head end will fall out of the rod-shaped article or be 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 not only has advantages with regard to the end product, but also with regard to the handling of the rod-shaped articles. Since the rod-shaped articles are often conveyed with compressed air in the production process, improved positional stability of the individual strips is advantageous with regard to the achievable quality of the individual rod-shaped articles. In other words, the probability is reduced that individual strips will protrude from the end face of the head area of the rod-shaped article due to the treatment in the production process.
  • the flat sheet can be reconstituted tobacco material (Recon film). This can be produced using the slurry process or the paper process.
  • the flat sheet 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) are made from Recon film, cooling elements, spacer elements or filter elements can be made from film, paper or cardboard for or as rod-shaped articles in the tobacco processing industry.
  • the embossing device includes an adjusting device with which a height of the embossing can be changed.
  • An embossing height is a maximum distance of an elevation or depression from a plane in which the surrounding material of the flat sheet or strip extends. Only the amount of this distance is considered, i.e. no distinction is made between elevation and depression in terms of their 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 weaker (low height).
  • An embossing with a large height, in which the individual elevations and depressions protrude a comparatively large distance from the plane of the flat web or from the plane of the strips, causes an increase in the filling power of the strips.
  • 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.
  • a pressure applied by the embossing roller(s) to the flat web or the majority of strips offers a simple control variable with which the height of the embossing and thus, for example, the filling power 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 articles produced from the strand.
  • the control unit is set up to: To control and/or regulate the height of the embossing with the adjusting device depending on the measured physical parameter.
  • the device comprises at least one sensor unit, which is set up to measure at least one physical parameter of the flat web of the strand or of the rod-shaped articles produced.
  • at least one physical parameter can be measured at one point, for example on the flat web, 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 can be.
  • any combination of these measurements is also possible.
  • the device according to this embodiment allows 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 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 articles as a physical parameter.
  • the thickness measuring device is in particular a non-contact thickness measuring device.
  • the material thickness is measured using a light system or an ultrasound system.
  • the strand forming device is further set up to cut the produced strand into individual rod-shaped articles, and the sensor unit is for this purpose set up to carry out an individual test on the cut 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 to the flat web or the plurality of strips by means of the embossing rollers, can be controlled and / or regulated as described, for example EP 0 242 824 B1 is described.
  • the height of a trimmer disk is changed using 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 system implemented according to the invention.
  • Sensor units for determining the mechanical hardness and/or the tensile resistance of the strand are, for example, from EP 0 284 640 B1 known.
  • the embossing is carried out intermittently.
  • the embossing device is set up to introduce an intermittent embossing into the flat web or the majority of strips.
  • the flat web is in a non-embossed state in some areas, and in an adjoining section it is again in an embossed state.
  • These embossed and Non-embossed areas alternate, preferably alternate regularly.
  • the positions of the embossed and non-embossed areas are coordinated with the position of the strips in the rod-shaped article produced.
  • appropriate position control can be carried out or provided. It is thus advantageously possible to provide rod-shaped articles which comprise embossed stripes in certain areas and non-embossed stripes in other areas.
  • the strips cannot be embossed, so that a heating mandrel, a heating shield or the like can easily be inserted into 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 imprint may be weaker in some areas than others. Here too, weakly embossed and more heavily embossed areas can alternate, in particular regularly alternating, as previously described with regard to the non-embossed and embossed areas. Similar advantages arise.
  • the embossing can also be continuously variable and, for example, follow a periodic function. In other words, a height of the embossing varies periodically along the longitudinal direction of the strips.

  • a reverse course of the thickness of the embossing can also be provided.

  • a three-dimensional shape into the strips present in a strand, a strand with higher filling power can be provided.
  • the method for producing the strand in the tobacco processing industry has the same or similar advantages as those already mentioned with regard to the device.
  • the method offers an additional control and/or regulation 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 by actively readjusting the parameter.
  • the method is developed in that the adjusting device is used to change a pressure applied by the embossing device, in particular by at least one embossing roller, to the flat web or the majority of strips.
  • a material thickness of the flat web is measured as a physical parameter using the sensor unit.
  • the sensor unit measures a mechanical hardness and/or a tensile resistance of the strand and/or the rod-shaped articles as a physical parameter.
  • individual rod-shaped articles are cut to length from the produced strand using the strand forming device.
