Definitions

  • the present invention relates to a device for processing tobacco having a tobacco conveying path, a tobacco inlet region and a tobacco outlet region, wherein the tobacco conveying path has a feed device which is designed such that the tobacco can be conveyed along the tobacco conveying path from the tobacco inlet region to the tobacco outlet region.
  • Such devices are known in the art. In general, these devices are used to transport the tobacco from one processing point to the next processing point. Thus, so-called cut tobacco is produced, for example, by cutting tobacco leaves. After cutting the tobacco leaves then present in the form of a tobacco mat tobacco usually passes through a drying plant with an outlet temperature of about 60 ° C to 85 ° C. In the subsequent cooling system, the tobacco is cooled to room temperature. In order to fix the filling volume to be achieved later and the outlet moisture of the tobacco, rapid cooling of the tobacco is advantageous in this case.
  • cut tobacco In cut tobacco, a distinction is generally made between volume tobacco for machine cigarette production, stop tobacco for manual cigarette production in prefabricated paper envelopes with suitable stuffing machines (MYO, make your own) and fine-cut tobacco for manual self-turning into a paper strip (RYO, roll your own).
  • MYO suitable stuffing machines
  • RYO fine-cut tobacco for manual self-turning into a paper strip
  • the present invention relates in particular to the production of fine-cut tobacco.
  • smaller tobacco leaves are used for the production of fine-cut tobacco. This also results in the main difference, namely that the tobacco leaves are not stripped.
  • barking is meant in tobacco production the removal or cutting out of the main rib of a tobacco leaf.
  • the tobacco leaf ribs next to the tobacco leaves remain in the finished fine-cut tobacco, a particularly homogeneous mixing of fine-cut tobacco components is sought.
  • the tobacco leaves are cut as perpendicular to the main rib, as shown schematically in Fig. 1 is shown.
  • the device according to the invention is characterized in that the device has an inlet air device, wherein an air cushion can be generated below the tobacco conveyed along the tobacco conveyor section and above a first rotatable feed body by the supply air device.
  • an air cushion can be generated below the tobacco conveyed along the tobacco conveyor section and above a first rotatable feed body by the supply air device.
  • the device according to the invention is characterized in that the feed device has at least one rotatable first feed body and at least one rotatable second feed body.
  • the first feed body and the second feed body are arranged on opposite sides of the tobacco conveying path. This arrangement ensures a particularly homogeneous mass flow of tobacco leaves and supports the alignment of the tobacco leaves, so that they can be fed in the desired orientation of the crushing.
  • the device has both an inlet air device and a first and second rotatable feed body.
  • a particularly advantageous alignment of the tobacco leaves along the tobacco conveyor section can be achieved.
  • the first feed body is arranged along the tobacco conveying path below the tobacco conveyor track, the second feed body being arranged along the tobacco conveyor track above the first feed body, in particular symmetrically to the tobacco conveyor track.
  • the first feed body rotates in a first direction and that the second feed body rotates in a second direction, wherein the second direction is opposite to the first direction. So can a very homogeneous distribution the tobacco leaves are achieved. Furthermore, it can also be achieved with this arrangement that the interwoven and intertwined tobacco leaves are separated.
  • first feed body and the second feed body rotate at different rotational speeds. This contributes to the unbundling and homogenization of the tobacco leaves.
  • the feed device has at least one rotatable third feed body, wherein the first feed body and the third feed body rotate at different rotational speeds.
  • the different rotational speed has the advantage that the tobacco or the tobacco web to be transported can be compressed and / or stretched. Thus, the tobacco leaves can be pulled or combed longitudinally. Therefore, a particularly good alignment of the tobacco leaves is possible.
  • the third feed body is arranged closer to the tobacco outlet area than the first feed body, wherein the third feed body rotates at a higher rotational speed than the first feed body. This has the advantage that the tobacco to be transported or the tobacco fleece is slowly pulled apart. This results in a particularly good alignment of the tobacco leaves.
  • the feed body has a lateral surface and at least one feed body - for example, the first and / or the second and / or the third feed body - radially extending from the lateral surface entrainment devices. This results in the advantage that the tobacco leaves are combed or pulled particularly well and so optimal alignment and separation of the tobacco leaves takes place.
  • the driver devices are radially extendable from the respective lateral surface, and preferably are completely retractable in the feed body.
  • the tobacco introduced in the tobacco inlet area is thus transported along the tobacco conveying path by rotation of the first feed body.
  • the extendable entrainment devices are in particular extended so that they act directly on the tobacco to be transported or the tobacco web to be transported. After they have acted on the tobacco or tobacco fleece, they are retracted again.
  • This has the advantage that the lateral space requirement for the entrainment devices is saved so that the first advancement body can be positioned close to the tobacco inlet area or to the tobacco outlet area.
  • This also has the advantage that the distance between the feed body and an adjacent component of the device (for example, to a third feed body) can be selected extremely low.
  • Driving pins have the advantage that they have a uniform cross-section in the longitudinal extent, so that they complete in the retracted state, the lateral surface completely and no residual opening remains, as would be the case for example with tops or cones.
  • first feed body and the second feed body are arranged substantially parallel to one another, wherein the distance between the first feed body and the second feed body is variable. In this way, for example, the amount of supplied air and thus the air cushion generated below the tobacco can be adjusted.
  • the first feed body and / or the second feed body and / or the third feed body are formed as rollers.
  • Rolls have the advantage that they are rotationally symmetrical and therefore the distance between the rollers can be optimally adjusted.
  • the feed body use according to the requirements, for example, cones or the like can be used.
  • the device has a housing, wherein the tobacco conveying section is arranged within the housing, and the inlet air device has a supply air opening arranged on the housing below the tobacco conveyor section for the discharge of air and an exhaust opening arranged above the tobacco conveyor section on the housing.
  • This has the advantage that the air necessary for generating the air cushion is introduced from below to the tobacco, flows past the feed bodies, then expands and thus a homogeneous air cushion is formed. Subsequently, the air is removed from the device through the exhaust port and can be filtered, for example, to eliminate dust or the like.
  • compressed air can be introduced into the feed body.
  • This compressed air which is also referred to as blocking air, can also be made available via the supply air device, for example.
  • the device is formed substantially completely symmetrical to the tobacco conveyor section.
  • several parallel feed body can be provided not only below the tobacco conveyor line, but also above the tobacco conveyor line.
  • These further feed elements parallel to the second feed body could, for example, be referred to as fourth feed bodies.
  • these can also rotate at different rotational speeds. In particular, it is advantageous if the rotational speeds increase from the tobacco inlet area to the tobacco outlet area along the tobacco conveyor line.
  • Fig. 1 shows a schematic representation of a tobacco leaf 101 as it is used for the production of fine-cut tobacco.
  • the tobacco leaf 101 has a main rib 102 and is preferably cut perpendicular to this main rib 102.
  • the tobacco leaf is cut along substantially parallel cutting axes 103 by a suitable cutting device 104.
  • the tobacco leaves 101 are fed in an aligned manner to the cutting device 104, that is to say along the longitudinal axis or along the main rib 102 in the example shown.
  • Fig. 2 is a schematic overview of a device 1 according to the invention for processing tobacco T, in particular of tobacco T which is used for the production of fine-cut tobacco.
  • the device 1 has a tobacco conveying section 2, a tobacco inlet section 3 and a tobacco outlet section 4.
  • the tobacco conveyor section 2 has a feed device 5, which in the in Fig. 2 shown exemplary embodiment of six feed bodies 6, 7, 8 consists.
  • the feed body 6, 7, 8 are formed as rollers and can each be rotated about a central axis X by a drive, not shown. It is irrelevant whether each roller 6, 7, 8 has its own drive, or a single drive drives all rollers 6, 6, 7, 8, for example with intermediate gears. However, the drive of the rollers 6, 7, 8 is formed so that the rollers 6, 7, 8 can rotate at different rotational speeds V.
  • the rollers 6, 7, 8 are constructed substantially identical. Each roller 6, 7, 8 has a lateral surface 9 from which driver devices 10 can be extended in the radial direction.
  • the driver devices 10 are preferably designed as driver pins, which are completely retractable into the lateral surface 9.
  • compressed air in the rollers 6, 7, 8 can be introduced, so that the interior of the rollers 6, 7, 8 is not added to the internal mechanism by dust or the like.
  • the compressed air which is also referred to as blocking air, can be provided, for example, via a supply air device 11, which will be described below.
  • the driver pins 8 can be arranged in rows along the longitudinal axis A of the roller 6, 7, 8. It is also conceivable that the driving pins 8 have a different arrangement, for example in the form of a helix or be arranged offset between the rollers 6, 7, 8, as for example in Fig. 4 is shown.
  • the driving pins 10 are moved in the radial direction via a movement device, not shown, so that they either extend from the lateral surface 9, or are sunk within the lateral surface 9.
  • the rollers 6, 8 forming the first feed body and the third feed bodies are arranged parallel to one another along the tobacco conveying path 2 at a variable distance D from one another. Since the driving pins 10 are retractable and extendable, the minimum distance D between two rollers 6, 8 and 8, 8 is not defined by the radial extent of the driving pins 10. Rather, the rollers 6, 8 are arranged so that contact the lateral surfaces 9 or just have no contact with each other. As shown in the figures, the driving pins 10 are shortly before they act on the tobacco T radially extended and after they acted on the tobacco T retracted again. For example, this input and extension movement of the driving pins 10 by a within the roller 6, 7, 8 arranged camshaft can be controlled. As in particular in Fig. 2 and Fig. 3 illustrated, the drive pins 10 are preferably about or extended in the upper third of the roller cross section, so that no contact between driving pins 10 adjacent rollers 6, 8 and 8.8 is formed.
  • the roller 7 forming the second feed body is arranged above the tobacco conveying section 2 next to the tobacco inlet region 3. Especially the roller 7 is arranged symmetrically to the roller 6 forming the first feed body. Further, the roller 6 rotates in a first direction R1, namely in the clockwise direction, whereas the roller 7 rotates in a direction R2 opposite thereto, namely counterclockwise.
  • the device 1 has a housing 12 and an inlet air device 11.
  • the tobacco conveyor section 2 is arranged within the housing 12.
  • the supply air opening 13 is in this embodiment below the tobacco conveyor section 2 and the exhaust opening 14 above the tobacco conveyor section 2. It is also conceivable that more than one inlet opening 13 or exhaust opening 14th are provided and these can also be arranged at other locations of the device 1 and the housing 10.
  • air L is abandoned with a selected flow rate S. In this way, an optimal air cushion can be generated below the tobacco T along the tobacco conveyor section, as will be described in more detail below.
  • the distance D between the rollers 6, 8 and 8, 8 is chosen so that an optimum air cushion is generated.
  • the tobacco T is placed in the tobacco inlet area 3 in the device 1.
  • the abandoned tobacco T is abandoned in this embodiment in the form of a tobacco mat T from uncut tobacco leaves. Since the tobacco T is subsequently to be cut, a sorting or alignment and separation of the individual tobacco leaves takes place along the tobacco conveyor section 2.
  • the tobacco mat T is conveyed along the tobacco conveyor section 2 by the feed device 5 and simultaneously combed or pulled by the different rotational speeds V of the rollers 6, 7, 8.
  • the rotational speed V of the rollers 6, 8 is continuously increased from the tobacco inlet portion 3 to the tobacco outlet portion 4.
  • the roller 6 closest to the tobacco inlet portion 3 rotates at the lowest rotational speed V
  • the roller 8 closest to the tobacco outlet portion 4 rotates at the highest rotational speed V.
  • an additional meshing occurs through the roller 7 forming the second feed body which rotates in an opposite direction R2 to the roller 6. It is also conceivable here that the rotational speed V of the Roller 7 is different from the rotational speed V of the roller 6, for example, is lower.
  • the distance D between the rollers 6, 8 is in this case chosen so that at the respective point within the tobacco conveyor section 2 no unwanted particles due to gravity fall through the gap defined by the distance D between the rollers 6 9, and enforce this ..
  • the clogging of the gap between the rollers 6, 8 or 8, 8 can be additionally prevented.
  • the air L flows through the gap between the rollers 6, 8 and 8, 8 wherein the flow rate S of the air L decreases due to the Bernoulli effect, when it exits through the gap 9 in the direction of the tobacco web T.
  • the air L is distributed homogeneously below the tobacco web T and thus produces the desired air cushion.
  • the air L then exits through the exhaust port 14 and can be filtered, for example, to remove dust particles or the like from the air L.
