Definitions

  • the invention relates generally to a filter material processing and the production of a filter from a filter tow. More particularly, the invention relates to a filter material processing apparatus for use in a filter manufacturing machine of the tobacco processing industry and a method of operating a filter manufacturing machine of the tobacco processing industry, wherein filter tow is processed in a filter wire processing apparatus and discharged flat from the filter wire processing apparatus.
  • the invention deals with the introduction of a further material into the filter tow, namely a pulverulent, granular and / or fibrous material, such as, for example, an activated charcoal granulate or a flavoring agent, for example a powdered flavoring agent.
  • a filter strand manufacturing machine in which in a filter treatment section, a filter web of a fibrous tow is formed.
  • a scattering device is provided, by means of which a carbon granulate is applied to the filter web. It is then provided a guide surface, by means of which the filter web is conveyed to an inlet funnel of a stranding machine.
  • This object is achieved by the use of a spreader roller for transverse axial spreading of a longitudinally supported axial strip of a filter tow of the tobacco-processing industry for the uniform entry of a material to be registered.
  • a spreader roller is understood in the context of the invention, in particular a roller having a bendable central axis and / or is made of an elastomer.
  • the elastomer is preferably rubber.
  • the spreader roll is in particular bent.
  • the spreader roller rotates about the then bent central axis.
  • the bending or the bend of the spreader roll symmetrical.
  • the roller may be formed for example in the form of a bent cylinder.
  • a spreader roller is preferably a roller which further extends or holds the width of a strip of a filter tow which has already been pulled apart by a certain width, namely by processing in the filter wire processing device or a filter tow preparation machine.
  • a kind of flexing movement of the spreader roller in this case leads the filter tow when moving over the roller or when conveying the filter tow over the roller to the two ends of the spreader roller.
  • It is, for example, a type of deflectable roller deviating from a cylindrical shape and formed, for example, at least partially of a flexible material, such as a rubber, with a central axis being curved and then correspondingly rotating around this central axis.
  • the curvature of the central axis can be generated by pressure exerted on the central axis in the axial direction.
  • a symmetrical bending of the central axis is present, so that a centrally located Towmaterial remains in the transverse axial position and corresponding tow material, which is spaced from the central position, further outwardly to the opposite sides of the spreader roller is promoted.
  • the orientation of the curvature of the spreader roll can be adjusted by rotating it about a theoretical axis passing through the centers of the bearings of the roll.
  • the size of the widening of the strip of the filter tow is adjustable.
  • a previous width of 20 cm can be brought to 20.5 cm or 22 cm.
  • the spreader roller is arranged upstream of a pair of rollers conveying the spread-out strip of the filter tow, wherein in the region of the roller pair the material, which is in particular a powder, granular and / or fibrous material, is introduced.
  • the name upstream is in relation to the conveying direction of the filter tow.
  • the pair of rollers clamps the filter tow between the two rolls of the pair of rolls and conveys them accordingly downstream or in the conveying direction, preferably in the direction of an inlet funnel of a stranding machine of the tobacco-processing industry.
  • the material prefferably be introduced in the region of the roller pair, that is to say in a region in which the filter tow is still in contact with a roller of the roller pair or shortly afterwards, that is to say downstream of the roller pair, but immediately downstream of the roller pair.
  • the filter tow is pulled apart, transverse to the direction of conveyance, into a flat ribbon-like filter tow.
  • This is preferably done in a filter trough preparation machine. If downstream of the pair of rollers followed by a conveying channel tapered in the conveying direction and then an inlet funnel of a stranding machine is provided, on the one hand, the registered material remains in the filter tow and on the other is thus little registered material lost. In addition, it remains thereby with a uniform distribution of the introduced filter material, since the converging in the conveying direction filter tow forms by providing a possible low level channel having in narrow waves or loops transversely to the conveying direction, so that the introduced material remains evenly distributed.
  • the spreader roll is preferably located downstream of a filter wire processing machine.
  • a filter material processing apparatus for use in a filter manufacturing machine of the tobacco processing industry, wherein a spreader roller is provided at an input of the filter material processing device and downstream of the spreader roller a conveying device conveying conveyor device is arranged in the conveying direction of a filter tow, wherein in the region of the conveyor Materialeintragvoriques is provided by means of a material is placed on or in the filter tow or is.
  • the feature in the region of the conveying device in this case in particular includes a location directly on or above the conveying device or shortly after, that is to say immediately downstream of the conveying device.
  • the conveying device can be, for example and preferably, a pair of rollers.
  • the pair of rollers comprises a driven and a revolving roller.
  • the spreader roll has a bendable central axis and / or is made of an elastomer, in particular rubber.
  • the spreader roll is bent during operation, in particular symmetrically.
  • a closed channel adjoins the conveying device in the conveying direction of the filter tow.
  • the material input device may be provided, for example, at the entrance of the channel and is in particular arranged between the entrance of the channel and the conveying device.
  • the channel tapers at a constant height transversely in the conveying direction and in particular, that is preferably, adjustable lateral guides on.
  • a closed conveyor channel is for example from the DE 38 23 707 A1 known.
  • the conveying channel preferably has a height in the range between 1 mm and 10 mm, in particular preferably at 3 mm.
  • the height of the channel is selectable depending on the bulk density of the material being introduced.
  • the delivery channel tapers as indicated in the conveying direction, so it is wedge-shaped and has a trapezoidal base.
  • the channel has an air-permeable bottom, in order to ensure that excess transport air or air that has accumulated in the spread filter tow can be conveyed away by promotion in a tapered channel and thus in a smaller volume without a Return air flow is formed, whereby correspondingly introduced material could be discharged again. It is preferably a fine-hole sheet in the air-permeable bottom.
  • a transparent lid is provided to allow the operator to monitor proper operation.
  • the channel is arranged approximately horizontally.
  • the channel is arranged slightly sloping in the conveying direction.
  • a closed channel prevents the registered material is distributed unevenly.
  • a small height of the channel is provided.
  • the waves or wrinkles that form in the channel have corresponding valleys, in which then the material, if this is relatively easy to move, deposits. Due to the small height of the channel, very many small waves or wrinkles result, so that there is a uniform distribution of the material as a whole. Without the closed channel large waves or large wrinkles would form, which thus have a larger period or greater distances, resulting in a more uneven distribution of the material in the finished filter rod.
  • the filter material processing device is further developed in that the output of the filter material processing device allows or provides a transfer of the filled filter material with a material in an inlet funnel of a filter rod machine.
  • the material input device comprises a metering device and a material storage.
