Definitions

  • This invention relates to a suction system for ring spinning machines, the system being arranged to remove trash, fibre fluff and broken threads from the space surrounding the spinning faces.
  • Said ring spinning machines normally comprise a plurality of working positions on two opposing faces, and are therefore very long.
  • Textile machines comprise suction ducts for the most varied purposes, for example to clean determined parts of the machine, to remove fibre trash and to draw off excessive yarn ends or pieces of cut yarn or the like. It is well known that in drafting systems of spinning machines, a fibre bundle consisting of an assembly of fibres of varying lengths is subjected to considerable traction stresses resulting in separation of a certain quantity of in particular short fibres and the formation of trash. It is therefore necessary to clean the drafting members and remove the flying fibrillae and fibres and the trash from the various machine parts and from the yarn under formation. It is also necessary to draw off and remove any pieces of broken yarn.
  • the suction action has to be effective and uniform along the entire spinning face.
  • the spinning faces of ring spinning machines are of considerable horizontal extension of some tens of metres, as the spinning spindles can be present in a quantity of the order of a thousand, one following the other.
  • the cross-sectional area of the air suction duct and the power of the pneumatic system therefore become relatively large, with consequent high system and operating costs.
  • the continuous draw-off of trash, fibres and broken threads in known systems is insufficient in those regions farthest from the motor-driven suction fan or other type of suction device which provides the suction action.
  • the air throughput in a central suction system, in which a suction duct extends along the entire spinning face to serve all the spinning spindles via suction nozzles or slits is represented by the total air quantity necessary in order to achieve an energetic suction action at the spinning spindles.
  • Fibres, dust and broken threads which have not been properly drawn off from the suction tubes often trigger their clogging, so blocking the suction action required for continuous cleaning of the spindles, which are hence subjected to progressive deposition of fibre trash on their various parts and on the yarn under formation. This results in yarn irregularities and defects which reduce its quality, such irregularities leading in the limit to yarn breakage during the formation stage or during subsequent yarn processing stages.
  • An object of the present invention is to provide a suction system for removing fibre trash and broken fibre pieces in spinning machines which is free of the aforesaid drawbacks and is able to perform its function with greater effectiveness and for a longer time, without requiring frequent maintenance.
  • a further object of the present invention is to rationalize the construction of the suction system of a ring spinning machine, both in terms of its capacity and of its suction efficiency in effectively removing fibrils and floating yarn pieces from the suction spindles.
  • a further object of the present invention is to provide a pneumatic suction system of new while at the same time simple concept, which makes it possible to put under suction several regions which integrate and complete the entire suction operation with further functions required for the particular application underway.
  • suction system of the present invention arranged on a spinning machine of considerable longitudinal extension, in particular a ring spinning machine, wherein said suction system comprises, along the entire length of the spinning machine, internal walls which converge in the direction of a mouth at the floor-level opening of ducting put under vacuum by the central suction system of the factory, said converging internal walls being sufficiently raised from the level of the floor on which the spinning machine rests, to allow energetic lateral draw-in of the air surrounding the spinning machine.
  • Figure 1 is a schematic sectional view perpendicular to the longitudinal axis of the spinning machine, showing the upper manifold channel which operates in cleaning the drafting rollers, and the profile of the internal walls which converge in the direction of a mouth at the floor-level opening of ducting put under vacuum by the central suction system of the factory.
  • Figure 2 is a front isometric schematic view of a longitudinal portion of the ring spinning machine suction system of the present invention.
  • the suction fan which puts the channel 2 under vacuum and the filter elements (not shown) are positioned at the end of the spinning machine 10.
  • the fibre trash and the dust present around the drafting unit 15 are drawn off by the slit in the tube 14 and conveyed into the manifold channel 2 which conveys them within its air stream to the end of the spinning machine 10 where they are retained by the filter surfaces. Simultaneously during the spinning process, the fibre trash, dust and broken yarn pieces present in proximity to the spinning spindle 11 are conveyed into the air stream 9, which conveys them together with the fibre trash of the air stream 7 into the ducting 6 of the factory suction system.
