Definitions

  • a hank carrier and stretching device comprises two drums around which the hank is to be wound and additionally stretched by movement apart of the drums.
  • the invention provides automatic means reducing the spacing between the drums when they are brought into a raised position for loading and unloading and when lowered to a working position the drums are automatically tension apart.
  • the device comprises a frame and pivotable carrier supporting the drums, there being means connected between the frame and a drum slidable on the carrier to effect the automatic tensioning and relaxation of the spacing between the drums as the carrier is pivoted between a vertical loading and unloading position and a horizontal working position.
  • the present invention relates to a hank-carrier which makes it possible not only to place a hank around a support easily but also to exert tension on this'hank automatically.
  • Hank-carriers which comprise two drums around which the hank to be wound is stretched.
  • One of the drums is movable with respect to the other which is termed stationary," so as to stretch the hank by increasing the spacing of the drums.
  • the two drums are mounted perpendicular to a common arm which can pivot about a horizontal pivot. This arm may swing between a horizontal and vertical position
  • the moving drum is moved by a mechanism controlled manually or by compressed air such that the distance between the axis of the two-drums is adjustable.
  • means are used, which are provided between the frame of the hank-carrier and the moving drum, and are capable, on the one hand, of separating the moving drum from the stationary drum so as to exert a permanent tension on the hank as soon as the pivot ing arm begins to pivot to its horizontal position and on the other hand, to bring the moving drum towards the other so as to be able to place a hank around the drums when the pivoting arm is caused to pivot to its vertical position and consequently the drums to their horizontal position.
  • this hank-carrier has the advantage that the moving drum is moved automatically in both directions on the pivoting arm by means of a relatively simple mechanism which requires neither manual operation nor compressed air to exert a tractive force on the hank. Moveroversince the traction on the hank occurs as soon as the arm begins to pivot downwards, the hank may no longer slide downwards on the drums.
  • FIG. 1 is an elevation view in partial section of a hank-carrier according to the invention not provided with a hank.
  • FIG. 2 is an elevation view in partial section of the front part of the hank carrier when the latter is in the non-operative position.
  • FIG. 3 shows the hank-carrier provided with a hank.
  • a tube 19 wherein a telescopic tube 20 slides.
  • This tube 20 is pivoted at one of its ends to the pivot 21 secured to the frame 1.
  • the other end of the tube 20 abuts against the pivot 18 secured to the carriage 8 when the drums l5 and 16 are not loaded with a hank.
  • a pin 22 is secured through the tube 19 and slides through the tube 20 in two slots 23 milled in the latter.
  • a draw-spring 24 (this could be a compression spring).
  • One of the ends of this spring 24 is secured to the pivot 21 and the other to the pin 22.
  • a support 29 which supports at its upper part a guide tool 30 along which the hank yarn is directed towards the winding machine.
  • This support may be moved with respect to the frame by means of slots 31 provided in the frame 1 and clamping bolts 32.
  • the spring 25 acts as braking means and the spring 24 exerts a tractive force on the carriage 8 such that the distance between the drums 15, 16 is increased.
  • the distance between the drums is selected such that it is possible to exert a sufficient tension on the hank. If necessary, this distance may be adjusted according to the perimeter of the hank, by moving the drum 16 on the arm 5 and then by immobilizing this drum by means of the clamp screw 11.
  • the pin 22 of the tube 20 is located at the end of the slots 23, the spring 24 then being at maximumtraction. The tension on the hank is then only exerted by the telescopic arm 19, 20
  • the yarn D of the hank B is directed, via the guide rod 29, towards the winding machine which is known per se and not shown and the hank is wound by the winding machine.
  • a hank-carrier, stretching device for winding sectional hanks of yarn comprising a stationary frame,
  • drums being adapted for a hank to be wound therearound for stretching
  • said shaft of a first of said drums being movably mounted on said arm and able to move away from a second of said drums to stretch said hank
  • means disposed between said stationary frame and said first drum for moving said first drum away from said second drum as said arm is pivoted from said vertical to said horizontal position and for moving said first drum towards said second drum when said arm is pivoted to said vertical position.
  • said means comprises a carriage slidably mounted on said arm,
  • said extensible. member comprises two cooperative telescopic elements
  • one of said elements is pivoted to said stationary frame at said second pivot and the other of said ele ments is pivoted to said carriage at said first pivot
  • an abutment means for limiting penetration of said two telescopic elements into each other.
  • telescopic elements comprise an inner telescopic tube having two slots and connected to said second pivot and an outer tube connected to said first pivot, and a pin integrally connected to said outer tube.
  • said spring means is connected to said second pivot at said stationary frame and said pin, said pin is perpendicular to a longitudinal axis of said tubes and passes through said inner tube through said two slots the length of said slots adapted to limit the extent of telescopic movement of said tubes, 5.
  • the hank-carrier as set forth in claim 1, further comprising a carriage bearing wheels which move along said arm, one of said drums is vertically mounted on said carriage, and a support selectively movable and securably mounted on said arm, the other of said drums is vertically mounted on said support.
  • bearings operatively mounting said drums to said carriage and said support, respectively.
  • a plurality of assemblies comprising said drums are mounted side by side on said frame.
  • the hank-carrier as set forth in claim 1, further comprising I a vertical support displaceably mounted relative to said frame, a guide rod means for directing along which yarn of said hank to a winding machine, and
  • said rod is mounted on said vertical support.
