Definitions

  • a filter manufacturing apparatus 1 includes, as sections for manufacturing a filter rod, a tow treating section 2, an additive feeding section 4, a shaping section 6, and a wrapping section 8.
  • the plasticizer feeding unit 26 includes a chamber 26A storing a plasticizer (triacetin) and a brush roll (not illustrated in the drawings) that rotates in the chamber 26A.
  • the brush roll rotates in the chamber 26A to splash and make the liquid plasticizer misty.
  • the misty plasticizer is discharged through a discharge port of the chamber 26A and adheres to the filter web WF (plasticizer feeding step).
  • the filter web WF to which the plasticizer has been added is provided with tackiness as a result of a melting effect of the plasticizer on cellulose acetate fibers.
  • Table 2 indicates results of two measurement processes for the classifying capability for each of the additives A to C with a weight of approximately 13 to 20 kg when the additives were classified using the classifier 38 according to the present embodiment.
  • [Table 2] Coarse grains Fine grains Remark on classification stat kg % g % A (first time) 20.25 99.928 14.52 0.072 Acceptable A (second time) 20.25 99.907 18.89 0.093 Acceptable B (first time) 12.98 98.632 7.39 0.056 Acceptable B (second time) 13.04 00.088 7.08 0.054 Acceptable C (first time) 13.02 99.541 14.36 0.110 Acceptable C (second time) 13.02 99.541 15.34 0.117 Acceptable
  • the filter manufacturing apparatus 1 feeds the activated carbon AC to the flat filter web WF shaped from the tow T to form a filter.
  • the present invention is not limited to this, and the present invention is applicable to formation of a filter including feeding the activated carbon AC among filter portions (filter elements) formed by cutting a filter rod.

Claims (8)

  1. Appareil de fabrication de filtre comprenant :
    une voie de transfert (30) à travers laquelle des éléments de filtre (WF) pour un article à fumer sont transférés ; et
    une unité de fourniture d'additif (36) prévue immédiatement au-dessus de la voie de transfert pour fournir un additif granulaire (AC) à chacun des éléments de filtre ou entre les éléments de filtre sur la voie de transfert, caractérisé en ce que
    l'unité de fourniture d'additif inclut un classificateur (38) classifiant l'additif en grains grossiers (CG) et en grains fins (FG) sur la base de la granularité pour enlever les grains fins immédiatement avant la fourniture de l'additif à chacun des éléments de filtre ou entre les éléments de filtre.
  2. Appareil de fabrication de filtre selon la revendication 1, dans lequel le classificateur est configuré pour filtrer les grains fins pendant la dispersion de l'additif en utilisant de l'air dispersé tourbillonnant et fournit, à chacun des éléments de filtre ou entre les éléments de filtre, les grains grossiers qui sont tombés contre l'air dispersé.
  3. Appareil de fabrication de filtre selon la revendication 2, dans lequel le classificateur inclut :
    une chambre de dispersion dans laquelle l'additif est introduit ;
    des moyens de fourniture d'air dispersé fournissant l'air dispersé dans la chambre de dispersion ;
    un tamis définissant une chambre de piégeage adjacente à la chambre de dispersion pour empêcher le passage des grains grossiers de la chambre de dispersion à la chambre de piégeage tout en permettant le passage des grains fins ;
    des moyens de récupération pour aspirer de l'air dans la chambre de dispersion depuis le côté de la chambre de piégeage pour récupérer, à travers la chambre de piégeage, les grains fins qui sont passés depuis la chambre de dispersion à travers le tamis ; et
    des moyens de fourniture pour recevoir, dans la chambre de dispersion, les grains grossiers qui sont tombés contre l'air dispersé et fournir les grains grossiers à chacun des éléments de filtre ou entre les éléments de filtre.
  4. Appareil de fabrication de filtre selon la revendication 3, dans lequel le classificateur inclut en outre :
    un nettoyeur nettoyant le tamis, et
    le nettoyeur inclut :
    une brosse à air agencée pour être mobile le long d'une surface arrière du tamis correspondant à la chambre de piégeage ;
    un moteur couplé à un centre longitudinal de la brosse à air pour entraîner en rotation la brosse à air le long de la surface arrière ;
    des moyens de fourniture d'air forcé pour fournir de l'air forcé depuis la brosse à air vers la surface arrière ; et
    une pluralité de trous d'éjection d'air ouverts dans la brosse à air et à travers lesquels l'air forcé est éjecté.
  5. Appareil de fabrication de filtre selon l'une quelconque des revendications 1 à 4, comprenant en outre :
    une unité de fourniture de plastifiant fournissant un plastifiant à chacun des éléments de filtre sur la voie de transfert.
  6. Procédé de fabrication de filtre comprenant une étape de fourniture d'additif consistant à fournir, au cours d'un transfert d'éléments de filtre pour un article à fumer le long d'une voie de transfert, un additif granulaire depuis immédiatement au-dessus de la voie de transfert jusqu'à chacun des éléments de filtre ou entre les éléments de filtre, dans lequel
    l'étape de fourniture d'additif comprend un processus de classification consistant à classifier l'additif en grains grossiers et en grains fins sur la base de la granularité pour enlever les grains fins immédiatement avant la fourniture de l'additif à chacun des éléments de filtre ou entre les éléments de filtre.
  7. Procédé de fabrication de filtre selon la revendication 6, dans lequel
    le processus de classification inclut la filtration des grains fins tout en dispersant l'additif en utilisant de l'air dispersé tourbillonnant et la fourniture, à chacun des éléments de filtre ou entre les éléments de filtre, des grains grossiers qui sont tombés contre l'air dispersé.
  8. Procédé de fabrication de filtre selon la revendication 6 ou 7, comprenant en outre une étape de fourniture de plastifiant consistant à fournir un plastifiant à chacun des éléments de filtre sur la voie de transfert.
