Definitions

  • This invention relates to a bobbin carrier mandrel projecting from a high speed yarn collection unit in continuous filament spinning plants, its projecting part being in the form of a single load-bearing external tubular body rigidly connected at its end to a positive drive.
  • the yarns leave the spinneret at various speeds, which are always high.
  • the productivity of the production processes and the efficiency of the operational equipment considerably affect market competitiveness.
  • This also includes improved machine construction, ie by providing a machine of improved quality or greater technological content.
  • the basic constituent members of the collection unit are a bracket-like support beam, which carries the presser roller and the yarn traversing system, the presser roller itself and the mandrel carrying the bobbins on which the yarn is wound.
  • the mandrel To perform its task, the mandrel must be able to clamp the tubes of the bobbins on which the yarn is wound, rotate them at the required speed, and finally enable the bobbins to be removed.
  • the mandrel being that rotating member which supports the tubes and rotates them at the appropriate peripheral speed, hence the mandrel must have a free end.
  • the outer diameter of the mandrel is determined by the inner diameter of the tubes, which are commercial elements constructed preferably of cardboard or plastic, and hence do not possess high dimensional precision. As the mandrel rotates at high speed it generates dynamic vibration, which compromises the life of the entire collection unit.
  • the problem of the mandrel is its mass, in particular the inertial mass related to dynamic vibration.
  • the primary objective of the present invention is to provide a mandrel arrangement which is improved by virtue of the following constructional and operational aspects:
  • An object of the invention is hence to provide a mandrel of simplified construction and perfect operation in particular at high speed, leading to better performance.
  • the projecting bobbin carrier part comprises, in coordinated cooperation:
  • 1 is the mandrel driver shaft of the known art
  • 2 is the element or block means arranged to move radially to clamp or unclamp the tubes 5 mounted one after another on the mandrel
  • 3 is the single external tubular body of the projecting part of the bobbin carrier mandrel, said body being made rigid with the shaft 1 by screw or similar means 10.
  • the tubular body 3 is advantageously of light composite material or carbon fibre; 4 are the inclined surfaces provided in limited regions in the surface of the tubular element 6. Said inclined surfaces 4 are provided at each hole present in the tubular body 3. Each hole and inclined surface 4 cooperate operationally with the block 2 and are distributed uniformly at uniform distance apart in the tubular body and tubular element 3 and 6; 7 is the outline of the bobbins under formation on the mandrel of the collection unit. Said bobbins 7 form on the tubes 5 clamped on the body 3 by the blocks 2, which emerge from the outer surface of the body 3 to press against the inner surface of the tubes 5; 6 is the tubular element inserted into and slidingly coupled to the tubular body 3.
  • the mandrel operation comprises the following operational stages: operating the actuator 12 so that its piston 9 causes a small but sufficient axial movement of the tubular element 6, which compresses the helical spring 8. Because of the provision of the inclined surfaces 4, the blocks 2 move radially into substantial alignment with the outer circumferential surface of the tubular body 3; mounting the tubes 5 by drawing them one after another along the tubular body 3 forming the load-bearing part of the improved mandrel of the present invention.
  • the tubes 5 can be moved axially along the tubular body 3 because the blocks 2 are able to move radially towards the interior of the tubular body 3, and hence do not form an obstacle; clamping the mutually adjacent tubes 5 by deactivating the actuator 12, which by retracting its piston 9 allows the spring 8 to exert its thrust action and extend to axially shift the tubular element 6 so that, via the inclined surfaces 4, the blocks 2 emerge radially from the outer surface of the tubular body 3 to clamp the tubes 5, which hence become rigid with the mandrel, ie with the tubular body 3; activating the collection unit in known manner to wind the yarn onto the tubes 5 rotating at constant peripheral speed.
  • bobbins 7 By moving the yarn along the lateral surface of the tubes (traversing), bobbins 7 form filled with wound yarn to a predetermined final diameter, as is well known to the expert of the art. When the bobbins 7 reach their final diameter, the mandrel ceases to rotate, in accordance with known operational procedures;
