Definitions

  • the invention relates to a cutting device for tobacco-filled cigarette tubes according to the preamble of claim 1. Furthermore, the invention relates to a tobacco recovery device with such a cutting device.
  • the reject cigarettes are subjected to a mechanical release effect and then subjected to a sieving process in the released state, for which purpose a machine with rotor and stator disks having release segments and a vibrating conveyor trough with a sieve insert are used coupled directly one after the other. Dry mechanical loosening in turn results in a considerable amount of paper dust and small paper particles and the risk of damage to the tobacco to be recovered, all of which have a negative effect on the quality of the tobacco that is recovered.
  • Such a medium such as compressed air or ultrasound according to preferred embodiments, can be metered and directed very easily and precisely, so that only a small area of the casing needs to be moistened only a little in order to be able to open the latter without problems.
  • a correspondingly small amount of fluid is not significant for mold formation and other problems that can arise from it.
  • the air flow can again be used to at least partially evaporate or blow away the amount of liquid used.
  • the corresponding humidity is sufficient to at least largely prevent dust formation, which is further favored by the precise local limitation of the treatment.
  • a preferred embodiment of the invention uses a fluid as the medium for transmitting force to the moistened area, as summarized in the preamble of claim 13.
  • compressed air can be used as the gaseous, inert fluid, which in accordance with claim 16 can additionally contain water vapor.
  • the latter variant makes it possible in a particularly advantageous manner to carry out the moistening and tearing open of the casing in a single process step, as is also determined by the information in claim 24.
  • Claim 27 designates an embodiment in which transport devices are provided for transporting tobacco-filled cigarette cases relative to the moistening and / or dispensing devices.
  • the transport means preferably we ⁇ antecess a transport channel along which, for example, tobacco-filled cigarette tubes by axially aligned in particular by compressed-air to the moistening and / or dispensing devices upstream beitransportierbar are.
  • the humidifiers and / or dispensing units for moistening or opening the cigarette sleeves can be moved in synchronization with the transportation devices for the transportation of the sleeves.
  • the transport devices contain at least one drum with circumferentially distributed, axially oriented receiving spaces for, for example, tobacco-filled cigarette tubes, and that the drum is arranged in such a manner relative to the moistening and / or dispensing devices is and the receiving spaces are open to its outer periphery to allow the moistening and opening of cigarette tubes.
  • feed devices can also be provided, by means of which tobacco-filled casings can be fed to the cutting device in a uniformly aligned manner.
  • the feed devices can contain a storage magazine, a removal device that can be connected to a cigarette manufacturing system, in particular with a quality testing device for the manufactured cigarettes and / or a reject buffer, separation and / or transport devices.
  • the tobacco recovery device according to the invention can be supplemented by the separating device being connected separately from receiving devices for recovered tobacco, cigarette paper and / or filter material.
  • the yield of the tobacco recovery device according to the invention can be increased if an input separating device, such as a vibrating screen, is provided for loose tobacco contained in the casings, upstream of the separating device and, if appropriate, downstream of the feed devices.
  • an input separating device such as a vibrating screen
  • FIGS. 2a) to 2e representations of different stages of treatment of cigarettes with a further embodiment of the separating device
  • FIG. 3 is a schematic diagram of yet another
  • the humidification devices 2 contain humidifiers 20 assigned to individual cigarette envelopes H. Although different types are shown in the figures la) to le), this is only used to demonstrate the possibilities. In practice, several, preferably identical, separating devices 1 are used next to one another, as is clear from the common representation of FIGS. 2a) to 2e), in order to manage the high volume by the tendon-running production machines for cigarette production with as little effort and space as possible can.
  • Media delivery can also be modulated using compressed air as well as ultrasound, i.e. that 3 pressure waves, fluctuations and / or fronts are generated or emitted in the medium M by the dispensing devices. This creates irregularities in force which lead to extraordinary tensions in the casing material which have a positive influence on the tearing process.
  • Cigarette wrappers H and the dispensing units 30 are in direct contact or a slight distance.
  • the envelopes H In order to open the tobacco-filled cigarette envelopes H over their axial length in the exemplary embodiments in FIGS. 1a) to le) and 2a) to 2e), the envelopes H must be guided past the fixed moistening and dispensing devices 2 and 3, respectively.
  • transport devices 4 are provided, which contain transport channels 40, along which the tobacco-filled cigarette tubes H are axially aligned and are transported past the humidification and dispensing devices 2 and 3 by compressed air introduced via transport air nozzles 44.
  • the transport channels 40 are arranged relative to the moistening and exhausting devices 2 and 3 in such a manner and are at least partially open, so that the cigarette tubes H can be moistened and opened without problems.
  • the cigarettes Z with the moistened area B are then guided past the nozzle 31, where their envelope H is suddenly torn open over its entire length by compressed air. If the open cigarettes Z are included their opening at least partially point downwards, tobacco T already falls out of the casings H due to gravity. This can be supported by a further or longer compressed air device. Individual features and advantages of this design can also be implemented or achieved with transport channels.
  • a corresponding tobacco recovery device can be completed and optimized in that the separating device 1 receiving devices for recovered tobacco T, cigarette paper and / or filter material, if necessary, are connected downstream from one another.
  • both pulsed and continuous operation are possible, for example.
  • the effective time e.g. the nozzles on the one hand or the compressed air or the ultrasound on the other hand is then determined either by the start of the pulse and the duration of the operation of the humidifier or dispensing units or by the timing of the movement of cigarette tubes past the moistening and / or dispensing devices.
