Definitions

  • This invention pertains to an installation for backwinding which comprises hank holders having two cylinders for holding a hank, each cylinder being rotatable about a shaft, the axes of said shaftsbeing substantially vertical, the one shaft being stationary while the other shaft is so mounted and guided as to be movable in parallel relationship with itself, to vary the spacing between both shafts.
  • the invention has for object to obviate these drawbacks and to provide an installation in which the dangers of catching threads in the hanks are substantially avoided, which allows to reduce to a large degree the manpower, the workers having substantially but to supply the hank holders with hanks.
  • Said installation due to the reliability of the hank unwinding allows to operate the winding-machine with a speed at least twice as high as the speed of known installations while enabling to wind heavier hanks than the ones used in the known installations, for instance acrylic fibre hanks of 2 to 4 lbs and hanks of carpet thread of up to l7 lbs.
  • the installation according to the invention has' moreover the substantial advantage of allowing to obtain collecting bobbins with an uniform hardness as thread-catching in the hanks is prevented and by the back-winding the thread tension is uniform which is not the case with the installations used up to now.
  • the installation comprises means for rotating about the shaft thereof at least the one cylinder of each hank holder during the hank unwinding.
  • said means are so arranged as to rotate each one of the stationaryshaft cylinders of every hank holder.
  • said means are so arranged as to impart to said cylinders a discontinuous rotating movement either clockwise or anti-clockwise.
  • said means comprise an endless strip moving over rollers with vertical axes and bearing on said cylinders to be driven, said endless strip being driven through a reduction gearing by a motor so as to impart thereto a slow motion.
  • the invention also pertains to a hank holder and particularly to a hank holder to be used in said installation.
  • the hank holder according to the invention has the advantage of allowing to design back-winding installations the holders of which have the same spacing as the spindles, which prevents the loss of spindles.
  • Said hank holder has moreover the advantage of allowing to replace rapidly the hanks on the holders. Indeed said holder may be re-stocked by a simple drawer-like motion, opposite the collecting bobbin thereof without having to be directed as in some known installations, to a central station for the re-stocking of the holders, the holders according to the invention each comprising means allowing the supply thereto of the hanks.
  • said hank holder comprises a frame on which is mounted the stationary cylinder shaft and on which is guided the movable cylinder shaft, said last cylinder being arranged on a movable support lwhich is attached to the end of the piston rod of a jack for changing the spacing between both cylinder shafts.
  • FIG. 1 is a diagrammatic elevation view of an installation according to the invention.
  • FIG. 2 is a partial perspective view of a back-winding installation showing a hank holder according to the invention.
  • the back-winding installation comprises hank holders l having two cylinders 2 and 3 which are respectively rotatable about substantially vertical shafts 4 and 5, shaft 4 being stationary while shaft 5 is so mounted and guided as to be movable in parallel relationship with itself, to vary the spacing between the shafts so as to allow re-stocking the holders with hanks and after such re-stocking, to stretch said hanks.
  • the installation comprises i means 6 for rotating about the shaft thereof the one cylinder of each hank holder during the hank unwinding.
  • said means 6 are advantageously arranged to rotate the cylinders whatever the spacing thereof, so as to rotate those cylinders 2 the shafts 4 of which are stationary relative to the hank holders.
  • Said means 6 are so arranged either as to impart to said cylinders 2 a continuous clockwise or anti-clockwise rotating motion, or to impart to cylinders 2 a discontinuous clockwise or anti-clockwise rotating motion, or else to impart to said cylinders 2 in a constant or discontinuous way, an alternating rotation about the shafts 4.
  • Said means 6 are comprised of an endless strip 7 moving over rollers 8 with vertical axes.
  • Said strip 7 bears on the cylinders 2 and it is driven by a motor 9 with reduction gearing so as to receive a slow motion.
  • the cylinders 2 are advantageously lined where they contact the strip 7 and so as to avoid any slipping of the cylinders relative thereto, with a nonslipping material 10.
  • a timer not shown is provided to energize and stop motor 9, while when to the strip is imparted an alternating motion, said strip 7 is provided with an element for operating a limit member (not shown) which reverses the rotating direction of motor 9, said motor being provided with a timer when said alternating motion is discontinuous.
  • the hank holder comprises as shown in FIG. 2, a frame 11 on which is mounted the' shaft 4 of cylinder 2 and on which is guided in a slide 12, the shaft 5 of movable cylinder 3, said shaft 5 being attached to a movable support 13 which is mounted at the end of the piston rod 14 of a jack 15 for varying the spacing between shafts 4 and 5 of cylinders 2 and 3.
  • the frame Il is advantageously comprised to have the total width of the holders substantially equal to the cylinder diameter, ofa box I6 inside which are mounted thejack l and so as to be slidable therein, said support I3.
  • the attachment means 3l for the jack l5 on frame 1l are adjustable in position so as to be able to change the location where said jack is attached relative to said frame according to the piston stroke length.
  • the frame of each holder is provided with casters 20 and guides 2l in such a way that the holder may move along a direction in parallel relationship with that plane going through the axis of shafts 4 and 5, a simple pull on the frame moving the holder away from the strip 7 and releasing the holder to be re-stocked from the adjacent holders.
  • each holder is provided with a caster 32 cooperating with the guides 2l and a limit member 33.
  • the holder frame comprises automatic locking members 22 which allow to secure said frame ll relative to a fixed beam 23 in parallel relationship with strip 7, in such a way that in the locked position, the cylinder 2 of each holder will engage the strip 7.
  • a circular crown 24 on which bears the hank is provided on each one of the cylinders 2 and 3 while a thread guide 25 is arranged by the upper end of each cylinder.
  • the thread guide 25 is mounted on the cylinder shaft and is rotatable about said shaft to allow adjusting the position thereof.
  • the thread guide 25 is comprised of a bent wire which forms a flat closed curve at right angle to the cylinder shaft axis and located below the level of end 26 of the cylinder, the closed curve being comprised of a half circle 27 with a diameter larger than the cylinder diameter which partly encompasses said cylinder, and of a loop 28 in the shape of an U the base 29 of which is substantially equal to the cylinder diameter.
  • the jack of each holder allows by means of a control pedal 30 to give an adjustable tension to the hank which may have varying circumferences during winding, said jack allowing moreover with a tangled hank termination, to locate easily the hank so as to prevent thread catching.
  • the locking members are advantageously so arranged as to be unlockable from the installation alley.
  • Each holder further comprises advantageously a system known per se for adjusting the jack working pressure.
  • a test installation provided with holders according to the invention has made it possible to increase fourfold the output of an usual installation for winding acrylic thread hanks of 100 to 200 grams.
