Definitions

  • the invention relates to a method and a device for providing a tobacco stream.
  • a device for foreign body separation from a tobacco stream is known for example from document US 6,332,543 B1.
  • a stream of tobacco is brought into the region of an optical foreign body detection device.
  • the foreign matter is excreted from the tobacco stream by means of compressed air transversely to the conveying direction of the tobacco stream.
  • EP-B-0 479 549 a device for sifting tobacco leaves is known.
  • the object of the present invention is to improve the separation of foreign bodies, in particular metal bodies, from a tobacco stream.
  • This object is achieved by means of a method for providing a tobacco stream, wherein a Popeniassenstrom is promoted with tobacco material to a first lock device are discharged from the output mass flow means of the first lock device foreign body-loaded portions of the output mass flow, so that a first substantially foreign body-free tobacco stream is provided, and wherein subsequently the foreign body-loaded portions of the output mass flow are conveyed as a partial flow to a second lock device, by means of the second lock device, the foreign body are discharged from the partial flow, so that a second substantially foreign body-free tobacco stream is provided.
  • the invention is based on the idea that foreign bodies can be completely or almost completely eliminated from the initial mass flow or the further partial streams having foreign bodies by the series connection of several discharge stages. At each discharge stage, a (further) part of the tobacco is recovered or recovered.
  • the foreign body-containing sections of the initial mass flow are collected in a temporary storage, particularly advantageously in a storage shaft.
  • the temporary storage is arranged between the two lock devices, wherein the storage shaft is preferably filled from above with the foreign body-containing sections.
  • the partial flow is discharged from the intermediate storage, in particular storage shaft.
  • the foreign body-containing portions of the output mass flow collected and stored in the intermediate storage or storage shaft are detected by sensors, and a volume flow of the partial flow is discharged on the output side, in particular evenly, on the delivery side.
  • the Stausacht a Lenterechen is assigned to the delivery of the storage canopy, so that the discharge of the partial flow can be selectively influenced.
  • the partial stream is separated after discharge and / or the partial stream with a lower flux density or a lower volume flow than the output mass flow generated.
  • the foreign bodies are detected in the output mass flow and / or partial flow by means of a foreign body detection device of the respective lock device.
  • a lock means in particular a changeover shaft, of the respective lock device be actuated.
  • the method is further developed in that the foreign bodies are guided or precipitated substantially vertically downwards and / or that the starting mass flow and / or partial flow is transported substantially horizontally.
  • metal bodies are recognized as foreign bodies and / or excreted.
  • the second foreign body-free tobacco stream is added to the starting mass flow, in particular in front of the first lock device.
  • a further solution of the problem is by means of a device for providing a tobacco stream comprising a conveying means for promoting an output mass flow with tobacco to a first lock device for discharging foreign body-containing portions of the output mass flow, so that a first foreign body-free tobacco stream is provided, further comprising a conveying means for promotion the foreign body-containing portions of the output mass flow as a partial flow to a second lock device for discharging the foreign body from the partial flow, so that a second foreign body-free tobacco stream is provided.
  • a buffer store in particular a stacker shaft, is provided for the foreign body-loaded sections of the output mass flow, which is arranged between the first and second lock device.
  • a Austragungsmittel, z As an arithmetic unit or a Luiterechen provided on the buffer for discharging a partial flow. For this purpose, the amount of the transported foreign body-contaminated sections to a Litzrechen and discharged a finely metered and lower in its volume flow mass flow than the output mass flow.
  • a collecting container for the excreted from the partial flow foreign body is provided.
  • first and / or the second lock device each have a foreign body recognition device.
  • the first and / or the second lock device each have a lock means, in particular a changeover shaft, wherein the lock means can be actuated in the output mass flow and / or in the partial flow as a function of the recognized foreign bodies.
  • a compact construction of a device results when the conveying means, in particular conveyor belts, are arranged substantially horizontally for the output mass flow and / or the partial flow. As a result, at the end of the conveyor belts, the discharge of the foreign body-loaded portions of the output mass flow or of the partial flow in the vertical can take place.
  • a conveying member for conveying the second foreign body-free tobacco stream to the output mass flow, in particular in front of the first lock device, or to the first foreign body-free tobacco stream is provided.
  • the object is achieved by means of a tobacco processing plant, which is formed with a device according to the invention for providing a tobacco stream.
  • a tobacco processing plant which is formed with a device according to the invention for providing a tobacco stream.
  • a part of a tobacco treatment plant is shown in a perspective view.
  • an output mass flow 20 is passed with tobacco material below a sensor device 15.
  • metallic foreign bodies are detected in the tobacco product 20.
  • the sensor device 15 is formed for example with a search coil, which is sensitively set to metallic foreign body.
  • a changeover shaft 18 is provided, which is switched over in dependence on the detection of foreign bodies in the tobacco stream via the sensor device 15. If foreign bodies or metal bodies are detected in the tobacco product 20, the changeover shaft 18 is actuated such that the corresponding conveyor section is passed with the metal bodies in a vertically arranged stowage bay 25.
  • a transport element e.g. Conveyor belt is supplied, which is arranged below the conveyor belt 12.
  • This transport element is provided in Fig. 2 by the reference numeral 14.
  • the sensor device 15 and the changeover shaft 18 form a first lock device.
  • the foreign body-containing portions are collected, so that the stowage box 25 forms a kind of temporary storage.
  • the amount of accumulated tobacco is detected.
  • the amount of tobacco is conveyed to a Léerechen, so that at the end of a partial flow from the stowage box 25 via a hopper 27 is discharged.
  • the amount of partial flow is applied to a arranged below the storage shaft 25 conveyor belt 22 and transported past a second sensor device 26.
  • the foreign body present in the partial flow are detected, so that in dependence on the presence of foreign bodies in the partial flow on the conveyor belt 22, a changeover shaft 28 is actuated at the end of the conveyor belt 22.
  • the sensor device 26 and the changeover shaft 28 form the second lock device.
  • the switching shaft 28 is adjusted so that the metal body in a container 24th reach.
  • the foreign body-free portion of the partial flow is conveyed away via the other outlet of the changeover shaft.
  • This second foreign body-free tobacco stream is via corresponding conveying members, eg. B. a pneumatic conveying line, the output stream conveyed on the conveyor belt 12.
