Definitions

  • the foreign body recognition is preferably carried out by means of a detection of the brightness and / or color of the objects contained in the tobacco stream.
  • objects is meant in particular tobacco, tobacco leaves, cut tobacco and foreign matter.
  • the conveying speed of the tobacco stream is according to the DE 10 2004 015 463 B4 and also according to the invention between 6m / s and 30m / s, in particular between 17m / s and 30m / s.
  • the preferred speed is a very effective promotion of tobacco flow provided, whereby a very high throughput is possible.
  • EP 1 838 464 B1 For example, a method and apparatus for sorting a stream of generally flat and lightweight articles of different dimensions are known, wherein the articles to be sorted out are extracted by suction by suction from the main stream by suction.
  • the devices and the method according to the prior art all have the disadvantage that after sorting the Foreign bodies which are sorted out with any sorted out and actually good or acceptable tobacco leaves in a relatively large amount, so that a relatively high tobacco loss arises.
  • a re-sorting is necessary, which is carried out in the prior art on conveyor belts in an optical process. This leads to a very high expenditure on equipment and, in spite of everything, to results which can be improved.
  • Object of the present invention is to allow an improved rate of rejected foreign body to tobacco particles.
  • a control or regulating device 52 which, for example, determines the frequency or the rotational speed of the fan the conveying speed of the tobacco stream controls or regulates.
  • the speed can also be controlled or regulated via a pressure measurement by a pressure sensor 53 in the tobacco-free air flow in the feed pipe 33 or in the discharge pipe 31.
  • a portion of the conveying air for the regeneration for example, for cooling, is discharged from the discharge pipe 31.
  • delivery air quantities of about 24,000 m 3 / h are provided.

Claims (8)

  1. Procédé pour séparer des corps étrangers d'un premier flux de tabac (13), le premier flux de tabac (13) étant transporté aux alentours d'un premier dispositif de reconnaissance de corps étrangers (20) par un flux d'air (12, 32, 32', 34') et des corps étrangers (17) étant reconnus dans le premier flux de tabac (13) à l'aide du premier dispositif de reconnaissance de corps étrangers (20) sur la base d'au moins une caractéristique et étant ensuite séparés du premier flux de tabac (13) à l'aide d'une impulsion d'air comprimé (28), si bien qu'il soit formé le premier flux de tabac (13) libéré de corps étrangers (17) et un second flux (50) de particules de tabac (15) emmenées par l'impulsion d'air comprimé (18) et de corps étrangers (17, caractérisé en ce que le second flux (50), éloigné du premier flux de tabac (13), est accéléré et que, de nouveau, des corps étrangers (17) sont reconnus par un second dispositif de reconnaissance de corps étrangers (24) sur la base d'au moins une caractéristique et sont ensuite séparés à l'aide d'une impulsion d'air comprimé (28'), l'accélération du second flux (50) étant effectuée en amont du second dispositif de reconnaissance de corps étrangers (24) par une réduction du volume d'un canal d'évacuation (23, 44) pour le second flux (50).
  2. Procédé selon la revendication 1, caractérisé en ce que le second flux (50) libéré de corps étrangers (17) est ajouté au premier flux de tabac (13) en amont du premier dispositif de reconnaissance de corps étrangers (20).
  3. Procédé selon la revendication 1 ou 2, caractérisé en ce que la vitesse de transport du premier flux de tabac (13) est commandée ou régulée aux alentours du premier dispositif de reconnaissance de corps étrangers (20).
  4. Dispositif pour séparer des corps étrangers d'un premier flux de tabac (13), comprenant un dispositif (10, 11, 22) (dispositif d'amenée) amenant le premier flux de tabac (13) à un premier dispositif de reconnaissance de corps étrangers (20) et un premier dispositif d'éjection de corps étrangers (21) en aval du premier dispositif de reconnaissance de corps étrangers (20), le dispositif d'amenée (10, 11, 22) comprenant une source d'air comprimé (51) pour le transport du premier flux de tabac (13) et le premier dispositif d'éjection de corps étrangers (21) comprenant un premier dispositif à buse (21) à l'aide duquel des corps étrangers (17) sont susceptibles d'être séparés du premier flux de tabac (13) à l'aide d'air comprimé (28), ce dont il résulte un second flux (50) de corps étrangers (17) et de particules de tabac (15) emmenées par l'air comprimé, caractérisé en ce qu'il est prévu un canal d'évacuation (23, 44) par lequel le second flux (50) est susceptible d'être conduit, le canal d'évacuation (23, 44) étant conformé, en la direction de transport (19), au moins par tronçons, de manière rétrécissante et que sont prévus un second dispositif de reconnaissance de corps étrangers (24) et un second dispositif d'éjection de corps étrangers (25) en aval du second dispositif de reconnaissance de corps étrangers (24), qui comprend un second dispositif à buse (25) à l'aide duquel des corps étrangers (17) sont susceptible d'être séparés du second flux (50), le canal d'évacuation (23, 44) étant conformé de manière rétrécissante directement à la suite du dispositif d'amenée (22).
  5. Dispositif selon la revendication 4, caractérisé en ce que le canal d'évacuation (23, 44) est conformé, directement à la suite du dispositif d'amenée (22), comme un espace (44) dans lequel est disposé un corps d'écoulement (45).
  6. Dispositif selon la revendication 4 ou 5, caractérisé en ce que le canal d'évacuation (23, 44) dans lequel le second flux (50) est susceptible d'être conduit, débouche dans le, ou en amont du, dispositif (10, 11, 22) transportant le premier flux de tabac (13).
  7. Dispositif selon l'une des revendications 4 à 6, caractérisé en ce qu'un dispositif de commande ou de régulation (52) est prévu qui commande ou régule la vitesse de transport du premier flux de tabac (13) aux alentours du premier dispositif de reconnaissance de corps étrangers (20).
  8. Dispositif selon la revendication 7, caractérisé en ce que sert comme paramètre d'entrée de régulation, la fréquence d'un ventilateur (51) pour la génération du flux d'air de transport (32, 32').
