Definitions

  • This invention concerns a compensator device for the carriage that winds bobbins in textile machines with one or more bobbins, said device being suitable for enabling the sliver leaving a drawing frame or derived machine to be taken up.
  • the main object of the invention is to provide a compensator device able to convey, and maintain a constant length of the sliver between the exit of the drawing frame or derived machine and the intake of the sliver itself by the revolving funnel of the traversing carriage that winds bobbins.
  • Our invention fulfils its purpose of guiding the sliver along an obligatory path of an always constant length with a compensator device of flexible nature which is of simpler and more solid construction than the known devices and which also enables the length of the path between the delivery point and the take-up spindle to be kept as short as possible.
  • the present invention relates to a compensator device known from BE-A-659089 and consisting of a sliver flexible support arranged in a bow- shape and flexibly anchored at one end to the exit of the drawing frame delivery calender and at its other end to the bobbin-winding carriage transversing along theyarn bobbin being formed, along which flexible support the sliver is constrained to run at a constant arc length.
  • the compensator device consists essentially of a spring wire wound in coils with a spiral having its diameter and coil pitch differentiated in at leastthree different tracts, whereby the compensator is anchored at one end to the exit of the drawing frame calender and at its other end to the bobbin-winding carriage transversing along the yarn package being formed and whereby the sliver runs inside said coils.
  • the spirals of the first and last tracts have greater coil pitch and smaller diameter as compared to the middle tract and have the task of guiding the sliver and the additional task of imparting a false twist to it at the same time.
  • one of the spirals or both the spirals of the first and last tracts impart to the sliver a false twist which runs in the reverse direction in respect of the feed of the sliver itself.
  • the compensator device of this embodiment has the low inertia needed to resist the fatigue stress generated by its alternating movement in winding the yarn package.
  • An advantage provided by the compensator device of this embodiment lies in the fact that its low inertia facilitates the rapid alternating movement of the bobbin-winding carriage.
  • the inlet of the compensator device is secured to the drawing frame or like machine with appendages which are clamped downstream from the calender and the outlet of the compensator device is secured to the bobbin-winding carriage with an appendage of the sliver exit guide.
  • the inlet consists of two closed coils which have the task of giving necessary elasticity for the alternating movement of the compensator device, which swings and pivots on said coils in the vertical and horizontal planes.
  • the actual length of the compensator device does not vary with the variation of the position of the bobbin-winding carriage and therefore the length of the sliver running within the compensator device remains strictly constant, thus leading to perfect compensation.
  • the sliver flexible support 120 of this embodiment consists of spring wire wound in coils with a plurality of tracts of spirals having differentiated diameters and coil pitches.
  • the flexible support 120 consists essentially of spring steel wire wound in coils and stretching from the drawing frame 12 to the bobbin-winding carriage 18; said wire has a first tract 210 with coils spaced widely apart, a middle tract 310 acting as an elbow and having coils close together and with a larger diameter than the first tract 210, and a last tract 410 with coils spaced widely apart and a smaller diameter than the middle tract 310.
  • Anchorage means 30 and 31 respectively are envisaged at each end of the coiled wire and have the task of securing the inlet head 11 to the support 122 of the drawing frame 12 and the outlet end 13 to the bobbin-winding carriage 18.
  • Said anchorage means 30, 31 are solidly fixed to the relative end portions 11, 13 of the coiled wire, and said end portions 11, 13 respectively consist advantageously of a number of coils acting as an articulated joint and as a sliver guide at the inlet and outlet of the wire.
  • the end portion at the inlet 11 consists of two closed coils side by side 201 which have the task of providing the necessary elasticity for the alternating movement of the compensator device 110, which swings and pivots on the end coils 201 in the vertical and horizontal planes, whereby said two closed coils 201 are provided with appendages 130 that constitute the anchorage means 30 of Fig. 3a clamped to the support 122 of the drawing frame 12.
  • the outlet end portion 13 consists likewise of a closed coil 211 having an appendage 131 which constitutes the anchorage means and cooperates with a joint 132 mounted on ball bearings located on the bobbin-winding carriage 18.
  • the coils of the first tract 210 and/or last tract 410 can advantageously but not necessarily be wound in opposite directions such as to impart to the sliver 112 in the first tract a false twist that runs in the reverse direction in respect of the feed of the sliver 122 itself and to take away same in the last tract 410.
  • Fig. 4 shows a machine to which are fitted two compensator devices 110, according to the preferred embodiment, each of which serves a winding station located at the side of the machine.
  • the wire may consist of another suitable metal; it is possible to conform and fit the anchorage elements 30 and 31 differently without departing thereby from the scope of the invention.
