Definitions

  • the invention relates to a device and method for opening of reject cigarettes with or without filters.
  • the invention further relates to a device for separating waste material of cigarette production.
  • the invention relates to the field of cigarette manufacturing, in which rejects are obtained in the form of reject cigarettes, loose tobacco material and loose wrapping paper pieces. This scrap material is fed to a downstream separation so that the loose tobacco material and the tobacco material contained in the reject cigarettes can be used again to form a tobacco rod and the subsequent manufacture of cigarettes. The wrapping paper will not be used again.
  • the separation of the loose tobacco material from the wrapping paper pieces can be done in several ways.
  • a known separation is effected by the transport on shakers, the mesh size is selected so that tobacco material falls through, the coarser envelope paper pieces, however, remain on the screen.
  • two separate initial mass flows are generated, one containing the loose tobacco material and the other the wrapping paper pieces.
  • the slit Due to the elasticity of the slit wrapping paper, the slit in most cases remains closed so far that hardly or no tobacco material falls out. Only subsequently is the spoons cigarette "opened" by being bent or otherwise mechanically treated so that the slot continues to open and tobacco material can fall out.
  • One of the aims of the opening of the scrap cigarettes is to get the junk cigarettes along its entire length so that the tobacco material contained therein can be completely removed from the opened wrapping paper.
  • the scrap cigarettes are first aligned in an alignment device in a plurality of parallel tracks for a longitudinal axial promotion and then fed to a cutting device in which each of the plurality of parallel webs is associated with a rotating cutting blade, each on the corresponding path longitudinally conveyed scrap glass with a continuous Cut opens.
  • the cutting blade penetrates very little into the cigarette.
  • an exact longitudinal alignment of the reject cigarettes is necessary.
  • a problem encountered in some cases in opening the spoons is that the orientation and shape of the rotating blades may cause the sliced spoons to rotate about their axis during opening so as to form a spiral cut around the spoil cigarettes , Such spoiled cigarettes can then subsequently no longer be completely opened completely in order to remove the tobacco material contained therein, but they partially re-rotate due to their tension remaining in the wrapping paper and thus prevent the falling out of at least part of the tobacco material.
  • the diameter of cutting knives for slicing or perforating wrapping papers of broke cigarettes is typically about 50 mm.
  • a rotatable circular knife for cutting cigarette paper, provided with a mounting opening for attachment of the knife to the shaft of a cutting set and with a plurality of cutting teeth on the disc circumference, wherein the mounting hole located in the knife disc is in communication with an interrupted in the connection point knife edge, said Knife is formed of an elastically deformable material.
  • This circular blade has a toothed circumference with equidistant teeth. It can be placed on the shaft and removed from this single circular knives without the other cutting blades must also be dismantled.
  • the circular knife allows the wrapping paper of broke cigarettes along the entire tobacco portion cutting the cigarette linearly out of a filter and acting as a wedge that forces apart the sides of the opened wrapping paper to facilitate removal of the tobacco material from the broke cigarette.
  • a device for opening scrap glass with or without filter which are conveyed on a conveyor device with a plurality of parallel conveyor tracks with a direction parallel to a direction of transport longitudinal axial alignment through the device, with a plurality of rotating cutting blades, each engaged with one of the plurality of parallel conveyor tracks of the conveyor are arranged and their distance to the rejection cigarettes in the conveyor tracks is set or adjustable so that the cutting blade comes into shallow cutting engagement with a wrapping paper of the reject cigarettes, which is further developed in that the peripheries of the rotating cutting blades are provided with a serrated edge.
  • the blade when serrated, the blade has only a few points of contact with the wrapping paper, with the result that the pressure exerted at the points of contact is higher than if the blade were in contact with the crop at full length.
  • this penetration depth is limited to the height of the cutting teeth and is thus significantly lower than in the case of a rotating knife with a straight cutting edge. This contributes to the conservation of the tobacco material.
  • the cut is substantially free of paper snippets that could later contaminate the tobacco material.
  • Serrated blades tore up the material to be cut rather than cutting it.
  • the serration forms a superposition of a first serration with a first circumferential frequency of the waves and a second serration with a second circumferential frequency of the waves, wherein the first circumferential frequency is smaller than the second circumferential frequency, wherein the second circumferential frequency in particular an integer multiple of the first Circumferential frequency forms.
  • peripheral frequency in this context is to be understood as meaning the number of waves of the cut around the circumference of the circular cutting blade. Suitable units may be length-related units such as “waves per cm” or dimensionless units such as "waves over the entire circumference”.
  • the amplitude of the second wave cut is smaller than the amplitude of the first wave cut.
  • the higher frequency second serrated edge is a minor modification on the first serrated edge, resulting in particularly clean cuts.
  • the amplitude of the first wave cut can be kept smaller than without superposition by a higher-frequency second wave cut. The correspondingly lower penetration depth protects the tobacco material.
  • the rotating cutting blades are disc-shaped and provided on both sides with a serrated edge.
  • This has the advantage that the cuts are symmetrical and similar on both sides, whereby a very good opening of the rejection cigarettes can be achieved.
  • asymmetry of the cutting edge of the knife does not result in rotation of the broke cigarettes about their longitudinal axis.
  • an outer circumference provided with a serration on both sides is symmetrical in cross-section, in particular V-shaped. This ensures a linear cut.
  • a diameter of the rotating cutting blades is at least 10 times the diameter of the rejected cigarettes to be opened.
  • the diameter of such blades is in most cases greater than 80 mm.
  • the distance between the cutting blade and the rejection cigarettes can be chosen such that the cutting blade penetrates the rejection cigarettes only very slightly and tangentially, whereby the cutting blade comes in contact with the tobacco material to a very limited extent and this therefore degraded only to a very small extent.
  • this avoids that possibly in the tobacco material or in a filter used liquid-filled capsules are cut and their liquid leaking, resulting in a deterioration of the tobacco material for recovery.
  • a larger diameter of the cutting blades increases their life. This is the commonly used Cutting knife with a diameter of about 50 mm about 80 hours and can be multiplied by the magnification.
  • the conveyor and the rotary cutting blades have drives set to give a speed ratio between an outer peripheral speed of the cutting blades and a longitudinal axial conveying speed of the broke cigarettes that is above 110%, more preferably between 120% and 150%.
  • the speed is preferably not so great that the spoiled cigarettes are torn out of their promotion and pulled along by the cutting knives or thrown away.
  • the cutting blades are each arranged centrally above a longitudinal axis of the longitudinally axially conveyed reject cigarettes.
  • each conveyor track is associated with two cutting blades which are symmetrically disposed on both sides of a center of the conveyor track to intersect the broke cigarettes symmetrically on either side of their respective longitudinal axis.
  • a symmetrical force entry results during cutting, so that a rotation of the rejection cigarettes to their respective longitudinal axes is omitted even in the case when they are not frictionally or otherwise held on the respective funding and secured against rotation.
  • the object underlying the invention is also achieved by a method for opening of broke cigarettes with or without filter, wherein the rejection cigarettes on a conveyor are conveyed with a plurality of parallel conveyor tracks with a longitudinal axial alignment parallel to a transport direction by a device according to the invention described above, with a plurality of rotating cutting blades, which are respectively arranged in engagement with one of the plurality of parallel conveyor tracks of the conveyor and their distance to the rejection cigarettes in the Conveyor tracks is set or adjustable so that the cutting blade comes into a shallow cutting engagement with a wrapping paper of the reject cigarettes, wherein the peripheries of the rotating cutting blades are provided with a serrated edge.
  • This method according to the invention has the same features, advantages and properties as the device according to the invention described above.
  • the serrated edge achieves a clean and superficial incision along the entire length of the rejection cigarettes which does not or only very slightly affect the tobacco material in the reject cigarettes.
  • an outer peripheral speed of the rotating cutting blades is greater than a conveying speed of the broke cigarettes during cutting, wherein a speed ratio between the outer peripheral speed of the cutting blades and the longitudinal axial conveying speed of the broke cigarettes is greater than 110%, in particular between 120% and 150%.
  • the circumference of the cutting blade moves at an overspeed of 10 to 50%, or possibly more, than the scrap cigarettes to be cut, resulting in a continuous cut with extremely few paper snippets.
  • a device for the separation of waste material of cigarette production comprising an inlet for a reject mass flow comprising reject cigarettes with or without filter and with two outlets for two separately discharged starting mass flows on the one hand loose tobacco material and on the other hand loose wrapping paper pieces and optionally filters
