Definitions

  • the invention relates to a method for separating scrap material from cigarette production, in which a scrap mass flow comprising scrap cigarettes, loose tobacco material and loose pieces of wrapping paper is transferred into two separate starting mass flows in which loose tobacco material on the one hand and loose pieces of wrapping paper and possibly filters on the other hand are discharged separately.
  • the invention further relates to a device for separating reject material from cigarette production, with an inlet for a reject mass flow comprising reject cigarettes, loose tobacco material and loose wrapping paper pieces and with two outlets for two separately discharged starting mass flows with on the one hand loose tobacco material and on the other hand loose wrapping paper pieces and optionally filters.
  • the invention relates to the field of cigarette manufacture in which rejects arise in the form of reject cigarettes with or without a filter, loose tobacco material and loose pieces of wrapping paper.
  • This scrap material is fed to a downstream separation device for tobacco recovery, via which the loose tobacco material and the tobacco material contained in the reject cigarettes can be used again for the formation of a tobacco rod and the subsequent production of cigarettes.
  • a generic device for the recovery of tobacco from defective cigarettes is out EP 0 370 202 B1 known. This device processes faulty cigarettes that have been automatically sorted out by a rod machine or piecing machine during their production.
  • the reject mass flow is conveyed into a conical vibratory bowl feeder, which has a spiral-shaped transport path.
  • the transport tracks In their outlet, the transport tracks have several baffles running parallel to one another in order to divide the individual cigarettes into several adjacent rows.
  • openings are provided in the transport tracks through which the tobacco is screened from the rest of the mass flow.
  • a roller system is provided for tearing open the paper sleeves of the cigarettes.
  • other rejects In addition to rejected cigarettes, other rejects also get into the vibratory bowl feeder, namely loose tobacco particles, paper strips and filter rods.
  • a device for tobacco recovery which also has a vibrating conveyor bowl.
  • a paper suction device is provided above the vibrating conveyor bowl, which removes reject material from the transport path with the aid of negative pressure.
  • EP 0 634 259 B1 describes a ripper with which the material fed in is reduced in size and placed on a screen conveyor. The tobacco falls through the sieve, but the paper and filter plug remain on the sieve and are conveyed on.
  • a nozzle bar is attached below the screen about half the length of the screen conveyor, which lifts the paper, which is lighter than the filter plug, from the screen bottom.
  • a suction device which is attached above the screen conveyor, removes the paper with negative pressure.
  • a device which has a first sieve separating device which separates the loose tobacco from the waste mass flow.
  • the reject mass flow is then conveyed to a second separating device in which the paper and reject cigarettes are separated from one another.
  • EP 0 990 395 A1 a device for separating rod-shaped articles in the tobacco-processing industry for the purpose of recovering tobacco, the articles being fed to a separating means by a rotary plate aligned longitudinally and axially.
  • the supply and alignment of the articles is optimized by a guide channel which transfers the articles onto the turntable and is curved in the direction of rotation of the turntable.
  • the cigarette shot passes through a feed shaft onto a conveyor belt, which transfers the cigarettes through a viewing shaft into a guide channel.
  • Loose tobacco, shredded paper, individual topping leaves and the like are separated pneumatically beforehand through the viewing shaft and conveyed to the rear part of a vibrating screen.
  • the supplied cigarettes are accelerated in such a way that they are attached to the air by the flow guidance align with the curved wall of the duct section.
  • the aligned cigarettes are conveyed at high speed directly to the outer edge of the turntable, where they are fed to and separated from disks by the circulating conveyor belt, as it were as an endless strand.
  • the separated cigarettes reach the vibrating screen through an outlet channel, through which the main part of the loose tobacco falls onto a collecting belt.
  • the present invention is based on the object of improving the separation and recovery of tobacco material from a waste mass flow, with the loose tobacco in particular being returned as gently as possible.
  • a reject mass flow comprises reject cigarettes, loose tobacco material and loose wrapping paper pieces.
  • loose tobacco material on the one hand and loose pieces of wrapping paper and optionally filters on the other hand are removed separately from one another.
  • the reject mass flow is converted into a first partial mass flow with reject cigarettes and divided a second partial mass flow with loose tobacco material and loose wrapping paper pieces.
  • the first partial mass flow is conveyed to a separating device in which the reject cigarettes are aligned, the wrapping papers of the reject cigarettes are opened and tobacco material contained in the reject cigarettes is removed from the opened wrapping papers, so that the first partial mass flow after the separation of loose tobacco material and loose wrapping paper pieces and optionally filtering is composed.
  • Both the first partial mass flow and the second partial mass flow are conveyed into a separating device in which an output mass flow of loose tobacco material and an output mass flow of loose pieces of wrapping paper and optionally filters are formed.
  • reject cigarettes encompasses both filter cigarettes and filterless cigarettes and tobacco sticks wrapped in wrapping paper to which no filter has yet been attached.
  • the filters are still present in the first partial mass flow after the step of opening the wrapping papers. In many cases they are still related to the pieces of wrapping paper, but they can also be conveyed separately in the first partial mass flow.
  • the invention is based on the basic idea that the loose components of the reject mass flow are removed from the reject mass flow before the separating device and are further conveyed separately.
  • This measure has the advantage that the loose tobacco material and the loose pieces of wrapping paper are no longer conveyed through the separating device.
  • the tobacco material to be recovered is not subjected to further mechanical stress because the paper remaining in the mass flow has no effect on the loose tobacco due to its low weight, so that the loose tobacco is gently separated from the wrapping paper pieces can be.
  • the pieces of wrapping paper are not shredded any further, which facilitates and improves the subsequent separation from the loose tobacco material.
  • Another advantage is that the loose material in the form of loose tobacco material and loose pieces of wrapping paper no longer gets into the separating device and can therefore no longer block the rejected cigarettes. These can therefore be correctly aligned without interference and cut and opened along their full length by a cutting knife. A complete separation of the tobacco material and the wrapping paper can then take place.
  • the cigarette reject mass flow is divided into a first partial mass flow with reject cigarettes and a second partial mass flow with loose tobacco material and loose wrapping paper pieces in a chute, the reject mass flow falling through the chute and being acted upon from one side by a transverse air flow directed transversely to the direction of fall that collects loose tobacco material and pieces of loose wrapping paper and conveys them into a bypass line, while rejected cigarettes continue to fall in the chute.
  • a transverse air flow directed transversely to the direction of fall that collects loose tobacco material and pieces of loose wrapping paper and conveys them into a bypass line, while rejected cigarettes continue to fall in the chute.
  • transverse sighting is achieved when the transverse sighting air flow has a movement component against a direction of fall of the reject mass flow.
  • a particularly gentle procedure results when the transverse air flow is generated by an air flow source that is only used for this purpose.
  • the cross-sighting air flow is cool or can be tempered, which is advantageous over the use of a process air flow of the entire machine, which is generally warm and very dry due to continuous circulation.
  • Warm and dry process air has the disadvantage that the tobacco material is heated and dried out and is therefore less suitable for the formation of a tobacco rod. The tobacco material must then be cooled and re-moistened.
  • the dividing device is designed as a chute with a transverse sifter, the transverse sifter comprising an air flow source for a transverse air flow and a transverse opening in the chute, the air flow source comprising the transverse air flow in particular horizontally or additionally with a movement component against a direction of fall of the reject mass flow through the Fall shaft leads, the movement component opposite to the direction of fall is smaller than the horizontal movement component.
  • the component of movement against the direction of fall can therefore also be zero.
  • a component of movement in the direction of fall does not have to be ruled out, but leads to poorer separation results.
  • the chute is designed in such a way that deflection of the rejected cigarettes by the transverse air flow is absorbed.
  • the part of the chute directly below the transverse direction is arranged somewhat transversely offset with respect to the upper part, so that the rejected cigarettes are not deflected in the transverse directional air flow or only lightly hit a wall of the chute.
  • Alignment and control of the transverse air flow and the further falling reject cigarettes can be done, for example, by means of fixed or movable and possibly controllable guide plates or baffles.
  • the air flow source of the transverse sifter generates exclusively the transverse directional air flow. This means that the airflow coming from this airflow source is not used for any other purpose. This also means that the air flow source is not a process air air flow source of the cigarette manufacturing machine.
  • the air flow source of the transverse sifter is also advantageously designed not to heat the transverse sifter air flow. This also protects the loose tobacco material.
  • the transverse opening in the chute is smaller than an opposite opening for further conveying the transverse air flow and the loose reject material, with the chute in particular expanding in cross section from the transverse opening to the opposite opening.
  • a bypass line is preferably provided for directly conveying the second partial mass flow from the dividing device to the separating device, bypassing the separating device.
  • the bypass line which leads from the dividing device directly to the separating device, ensures safe and loss-free transport of the loose reject material in the second partial mass flow, possibly while maintaining the advantageous air conditioning of the transverse air flow.
