Definitions

  • the present invention relates to a method and an apparatus provided for carrying out the method for recovering components from rod-shaped bodies in the tobacco processing industry.
  • waste material is generated, the paper material, tobacco and / or at least one further component, such as e.g. Has filter material or filter plug, the paper material enveloping the tobacco and possibly related to the filter material.
  • filter rods are first produced from so-called filter tow strips, which consist of cellulose acetate filaments.
  • the filter tow strip or filter tow strips are drawn off from a bale or stack and further processed on a filter rod machine into filter strands covered with paper, after which individual filter rods are finally produced by cutting the filter strands.
  • These filter rods are cylindrical units encased in paper with a length of about 66 to 150 mm and a diameter of e.g. 4 mm to 10 mm.
  • Each filter rod normally contains enough material for four or six filter pieces or filter plugs that are wrapped in paper (tipping), which are later attached by means of a cigarette manufacturing machine to cigarette rods that contain tobacco wrapped in paper to produce filter cigarettes.
  • DE-AS 1 204 118 describes a device for recovering components from rod-shaped bodies, which a sieving device in the form of gear wheels, which break the bodies down into their individual components, is sieved out using a sieve device. Similar devices are also described in US-A-4,278,100 and US-A-4,083,499.
  • the object of the present invention is to propose a method and an associated device which enable the components, in particular the filter material and the tobacco, to be recovered from the rod-shaped bodies as gently and cleanly as possible.
  • a disassembly step in which the bodies in a mill are disassembled into their individual components in a dry-mechanical manner, the bodies, when disassembled, one or more radial jaws of a rotor of the mill, which are rigidly or movably attached to the rotor during operation, and one or pass through several stationary jaws of a stator of the mill which, during operation, has the M and a separating device which separates the individual components from one another.
  • US-A-4,618,415 describes a tobacco separator which separates light parts of the threshed tobacco from heavy parts of the tobacco.
  • US-A-4,651,757 describes an apparatus for recovering tobacco from cigarettes, in which the cigarettes are disassembled in a centrifugal mill with several stages and then the cool one is fixed rigidly or movably, and the radial jaws and the stationary jaws if they face each other, are spaced apart, and - A subsequent separation step in which the individual components are separated from one another.
  • the paper material in particular is detached from the other components such as the tobacco and the filters.
  • Dry-mechanical is to be understood as a mechanical action on the body, in which e.g. the bodies are broken down into their individual components by a tear, shear and impact action, this disassembly process taking place under dry conditions, that is to say without the use of a liquid or a fluid, and also the bodies themselves being in the dry state.
  • the components obtained in the first step are still mixed and are subsequently sieved to separate the tobacco.
  • the components can be set in vibration and spread out. From the components spread out in this way, the paper, which has already been detached or separated from the other material components, in particular from the tobacco that has been sifted out, can be sucked off in order to separate out or select the paper.
  • the paper Before sieving or suctioning, there is already digested waste material, i.e. the paper, tobacco and e.g. the filter plugs with tipping are still mixed, but due to the previously performed disassembly, the paper is no longer with e.g. connected to the tobacco or the filter material, so that a suction of the paper material or a sieving of the tobacco is made possible.
  • the device according to the invention which has a disintegration device in the form of a mill, which disassembles the bodies into its individual components, and which has a separating device, which separates the individual components from one another, the rotor of the mill having one or more radial jaws which are rigidly or movably attached to the rotor during operation, the stator of the mill having one or more stationary jaws which are rigidly or movably fastened during operation, and the radial jaws and the stationary jaws, when they face each other, are spaced from each other.
  • the special design of the mill ensures that the tobacco and the filter material are tipped very gently, which enables these components to be reused.
  • the distance between the jaws can be adjustable and is preferably 1 to 4 mm.
  • the radial jaws and / or the stationary jaws can also be designed to be adjustable.
  • the separating device can be designed as a vibrating sieve or vibrating trough, to which the disrupted components are fed from the mill and which carries the components along a plane inclined with respect to the direction of the horizontal, the angle of inclination being 4 ° to 12 ° can.
  • the vibrating screen can have a plurality of screens arranged one above the other.
  • the separating device can furthermore have a blower-operated suction device which sucks the paper material.
  • the suction device is preferably provided with a suction hood, which is arranged above the vibrating screen.
  • the separating device can also have a blowing device which blows on the digested waste material or the components in the vibrating sieve or acts on it with an air stream and can be provided with a nozzle bar.
  • the nozzle bar can be arranged in the area below the suction hood of the suction device, the screen extending between the suction hood and the nozzle bar.
  • the suction device preferably has a separating device, e.g. a deflection separator, which separates the extracted paper material from the exhaust air flow.
  • a blowing device is preferably used which applies an air flow to the separated waste material, which facilitates the removal of the paper material from the waste material.
