Definitions

  • the invention relates to a tobacco feeding device with a circulating air system for conveying and / or sifting tobacco by means of circulating air, with a ducting system for guiding the circulating air and with an air cleaning unit arranged in the piping system for cleaning the recirculated air of particles in the circulating air system, wherein the air cleaning unit has an air inlet, a Air outlet and has a particle outlet.
  • the tobacco In the production of rod-shaped smoking articles, such as cigarettes, it is known from the prior art, the tobacco first manually or automatically fed to a so-called tobacco feed device. As a result of the transport or storage of the tobacco, it can be compressed differently and, for example, have different densities and must therefore first be prepared for further processing into rod-shaped smoking articles.
  • delivery of the tobacco and processing of the tobacco take place in the form of loosening and sifting, before the tobacco can be processed further by means of further processing steps.
  • the tobacco is supplied to a strand unit, for example, via a suction belt conveyor, which transports the tobacco, like a continuous tobacco rod, to a strand unit.
  • the string unit ensures that the open tobacco rod wrapped in paper, usually brought into a cylindrical shape and the paper is glued. This creates an endless, guided tobacco rod.
  • This tobacco rod is then cut during transport through the strand unit into individual cylindrical tobacco rods, which usually have twice the length of the later finished tobacco rods in the product.
  • the tobacco sticks are then transported transversely to their longitudinal axis, since the tobacco sticks are otherwise not efficient and damage-free machinable and further processed.
  • the double-length shaped tobacco rods for the introduction or addition of filters are usually transported in troughs on the surface of rotating cylindrical drums, wherein the tobacco rods are arranged axially parallel to the axis of the drum.
  • the double-length shaped tobacco sticks are divided in the middle into two tobacco sticks, spread and a filter is placed between the two tobacco sticks. If now also the filter is divided again in the middle, you get two cigarettes of desired length.
  • the tobacco may also be supplied to a packaging unit, for example.
  • the tobacco is then packaged in individual portions to be sold in this form to consumers.
  • the "turning" of the cigarettes is then carried out by the consumer. But even in this case, a loosening and sifting of the tobacco and a corresponding transport of the tobacco must be done in the tobacco feeder.
  • cyclone separators consist essentially of an inlet cylinder, an adjoining cone, a particle container located underneath and a dip tube projecting into the cone or inlet cylinder as an air outlet.
  • the inlet cylinder the particulate air is forced through a tangential air inlet onto a circular path.
  • the rotational speed of the air flow increases and the particles are moved by the centrifugal force outwards to the conical walls and braked so far that they dissolve out of the flow and fall through a particle outlet down into a particle container.
  • the cleaned air leaves the cone then through the central dip tube upwards.
  • the object of the invention is to provide a tobacco charging device with an efficient and at the same time compact recirculating air system for conveying and / or sifting tobacco.
  • the object is achieved according to the invention in that the air inlet and the air outlet are arranged coaxially and that the air cleaning unit has a coaxially arranged vortex element extending over the cross-sectional area of the air cleaning unit for generating a vortex.
  • the proposed tobacco feeding apparatus can be made particularly efficient and at the same time compact.
  • the air inlet and the air outlet are arranged coaxially, a fluidically particularly advantageous geometric design of the air cleaning unit is achieved.
  • the air inlet to the air outlet can then be connected substantially in a straight line or axially. Any pressure or Saugkraftmaschinee can be minimized.
  • this achieves a substantially tubular design of the air cleaning unit, which can be integrated into the pipe routing system of the air circulation system, so that a particularly compact air circulation system is made possible.
  • the air is introduced into the air cleaning unit through the air inlet, the particles to be removed are removed at least partially via the particle outlet, and the cleaned air is removed again via the air outlet.
  • the particles for example dust, dirt or tobacco
  • the particles are moved radially outwards due to the centrifugal force and can thus be removed at the outer edge of the air cleaning unit via one or more particle outlets.
  • the generation of a vortex is understood in particular to mean that exactly one vortex is generated and not several.
  • the provision of a vortex element producing a single vortex is advantageous in terms of flow in comparison to a plurality of vortexes. Due to small local disturbances of the flow, it may happen that other, but much smaller (for example orders of magnitude smaller) vortexes are generated. However, these do not play a significant role in particle separation and are not considered to be eddies generated by the vortex element.
  • the cross-sectional area of the air cleaning unit preferably corresponds substantially to the cross-sectional area of the conduit system in the vicinity of the air-cleaning unit, so that a minimization of the flow negative influencing geometries can be achieved.
  • circulating air is understood in the context of the invention not only air, which has been removed from a volume and is reintroduced into this, but also air, which consists only partially of reused air.
  • air which consists only partially of reused air.
  • a part of the circulating air is discharged and is replaced for example by room air or fresh air.
  • the vortex element has at least two essentially radially extending guide surfaces.

  • the efficiency of the air cleaning unit can be further increased by the fact that the vortex element has at least four, preferably even more than six, more than eight or more than ten guide surfaces. With an increasing number of fins, a particularly homogeneous vortex for particle separation can be achieved even on shorter distances.
  • the guide surfaces are preferably fastened on a hub which is designed in a streamlined manner and is arranged coaxially with the air cleaning unit and with the air inlet or air outlet.
  • the swirling element is fixed in the air-cleaning unit, it is possible to dispense with moving parts, so that a further simplification of the construction of the tobacco-loading device is achieved.
  • the vortex is achieved solely by the circulating air passing past the vortex element, whereas the vortex element itself does not have to perform a translatory or rotational movement.
  • the circulation of the room air in the piping system can be generated by a fan, for example.
  • the air cleaning unit has a peripheral recess as a particle outlet behind the vortex element, a particle outlet can be provided which manages substantially without or only with minimal storage area.

  • the portion of the piping system following in the flow direction on the circumferential recesses may particularly preferably have a slightly smaller diameter, i. a slightly smaller cross-sectional area than the diameter or cross-sectional area of the air cleaning unit.
  • the air cleaning unit has a substantially rectilinear pipe section between the air inlet and the vortex element, a further increased air purification by particle separation can be achieved. This is due to the fact that the circulating air to be cleaned is calmed down before being influenced by the vortex element, ie a substantially laminar or rectilinear one Flow is achieved. By eliminating or at least reducing the turbulence in the circulating air impinging on the swirl element, the particles to be removed can then be effectively brought into the area of the particle outlet.
