Definitions

  • the present invention relates to an opening machine for separating the fibres from intermingled vegetable impurities in cotton tufts, of the type defined in the preamble to claim 1.
  • the invention also relates to a method of opening cotton tufts and the like.
  • Conventional opening machines comprise an upper storage bin or supply chamber into which the cotton tufts to be processed are introduced.
  • an opening cylinder (with prongs, needles or clothing) which cooperates with cleaning blades to split up the fluffy masses of cotton at least partially into their individual constituent fibres, eliminating the intermingled vegetable impurities (parts of leaves, of capsules, of seeds, earth, etc.) therefrom.
  • suction openings for removing the impurities separated from the fibres and a duct through which the impurity-free fibres are removed.
  • the material in tufts usually reaches the opening cylinder in the form of a compact mat.
  • the opening cylinder cannot achieve good separation of the fibres from the vegetable impurities, unless a clothing having quite “aggressive” characteristics towards the material to be treated is selected for the opening cylinder.
  • a clothing of this type brings about the breakage of a considerable quantity of fibres.
  • An object of the present invention is to provide an opening machine which can eliminate the disadvantages of the prior art discussed above.
  • Another object of the invention is to provide an opening machine which can operate with a shorter working cycle.
  • an opening machine according to the present invention is generally indicated 10 .
  • the general structure of the opening machine shown in FIG. 1 may be considered generally known; only the elements which are of specific importance and interest for the purposes of the implementation of the invention will therefore be described in detail in the following description. For the construction of the parts and of the elements which are not described in detail, reference may therefore be made to any known opening machine.
  • the opening machine 10 comprises a substantially vertical storage bin 11 in the upper portion of which there is an intake device 12 connected to a duct 13 for the supply of cotton tufts from the exterior.
  • An important characteristic of the solution according to the invention is that, in the lower portion of the bin 11 in which the tufts to be processed are stored, there is a set of three rollers which can perform a preliminary opening operation on the tufts and can supply the tufts to the opening cylinder 14 in a controlled manner and in an at least partially-opened and non-compacted condition.
  • Two feed rollers 19 and 20 are arranged substantially side by side in the lower portion of the storage bin 11 and are rotated in the directions indicated by the arrows in order to withdraw, in a metered manner, the material which is usually in a compacted condition in the base of the storage bin 11 , and to supply this material, in a less dense condition, to a pre-opening roller 21 .
  • the feed roller 19 has projecting peripheral elements 19 a adapted to force the tufts of material to fall into the passage between the rollers 19 and 20 .
  • the feed roller 20 has an outer clothing 20 a which serves to restrain the cotton tufts whilst they are located in the narrow passage between the rollers 20 and 21 and are subjected to a rubbing action by means of elements 21 a projecting from the periphery of the pre-opening roller 21 . Since the pre-opening roller 21 is rotated at a tangential velocity considerably greater than that of the clothed roller 20 and of the feed roller 19 , it brings about, by means of the outer elements 21 a, a preliminary or at least partial opening of the tufts which are dragged along by the clothing 20 a of the clothed feed roller 20 . By way of indication, the feed roller 20 rotates at a tangential velocity of between 1.5 and 4 m/min., whereas the preopening roller 21 rotates at a tangential velocity of between about 400 and 600 m/min.
  • the feed roller 24 which is disposed in the lower opening of the intermediate chamber 22 , is rotated at a tangential velocity greater than that of the feed rollers 19 and 20 so as to prevent accumulation of material in the intermediate chamber 22 .
  • the material coming from the pre-opening roller 21 reaches the final feed roller 24 in the form of non-compacted tufts.
  • the speed of rotation of the final feed roller 24 is preferably regulated in a manner such as to supply the material to the cylinder 14 with a theoretical delivery rate about 10 ⁇ 50 times greater, preferably about 30 times greater, than the delivery rate of the feed rollers 19 and 20 , or the quantity withdrawn from the base of the bin 11 thereby per unit of time.
  • the chamber preferably has a grating or perforated plate 23 which allows the air to escape and thus prevents the formation of undesired excessive air pressure inside the chamber.
  • the individual partially-opened cotton tufts are then passed from the chamber 22 to the opening cylinder 14 by means of the final feed roller 24 . Since the cotton tufts reach the opening cylinder 14 in an already partially-opened condition, the cylinder 14 can advantageously have finer or less aggressive clothings in order to process the cotton tufts more effectively and to separate their fibrous cotton fraction from the impurities without damaging or breaking the fibres.
