  • ABSTRACT Apparatus for automatic formation of a transfer tail on a continuous delivery winding device including a bobbin changer wherein an oscillating thread guiding device traverses the normal winding zone of a winding spool and shifts the yarn during bobbin change to the transfer tail zone at one end of the new or empty [30] Foreign Application Priority Data Oct. 23, 1969 Switzerland alone................,..15956/69 [52] U.S. Cl. A, 242/18 PW [51] Int. Cl.
  • my invention resides in the utilization of apparatus for the automatic formation of a transfer tail on a yarn winding device during continuous thread delivery characterized by a traverse device having guide means extending horizontally in parallel with the axis of a bobbin body and extending over the whole of the transfer tail zone as well as the winding zone of a take-up tube or bobbin, a carrier slidable relative to the guide means by means of a cord or rope drive mechanism, a yarn guide for receiving the advancing yarn during bobbin changing between an empty winding bobbin and a wound-up bobbin and shifting the yarn into the transfer tail zone situated selectively in one of the two peripheral end zones of the empty winding bobbin.
  • My apparatus may conveniently be mounted for operation with an automatic or semi-automatic bobbin changer by securing same on the frame of the machine which may be easily modified, if necessa-
  • the guide means may-comprise a pair of tubes extending horizontally and parallel to the axes of the bobbins and through which the driving cord or rope passes to shift the carrier; and the yarn guide may comprise a hook-shaped element borne by the carrier and able to pick up the advancing yarn during changeover to shift.
  • the present invention finds a useful application in connection with the structure.
  • the cord mechanism is connected to the levercontrolled switching hub by means of a spring box threaded into the latter with a preset tension spring supported therein and bearing against a sliding bolt receiving the ends of the cord mechanism arranged to shift the carrier when the bobbins are shifted by means of the lever.
  • Stop means may be provided at the end zones of the traverse device to limit the movement of the carrier; and means including a compensating spring may be provided to compensate for extension of the cord mechanism after the carrier has reached astop means and can proceed no further.
  • FIG. I is a perspective view illustrating a winding device incorporating apparatus according to the present invention and showing the same during winding with the yarn in central and in left extreme positions;
  • FIG. 2 is a perspective view of the apparatus illustrated in FIG. 1, but shown at the moment of formation of a transfer tail.
  • FIG. 1 there is shown a machine 1 of the semi-automatic bobbin changing type as mentioned hereinbefore, in which two starshaped bobbin supports 2 and 2' are connected by a shaft 2" for rotation thereabout.
  • the bobbins extending between the extremities of the bobbin supports may be shifted by means of a lever 4 fixed to a hub 3 and operable to rotate the same in the direction indicated by the arrow A; and a spring box 5 is rigidly connected with the hub 3 by screw 6 so that its longitudinal axis Y forms an angle a with the longitudinal axis X of the lever 4.
  • the spring box 5 actually constitutes one end of a cord or rope traction device and serves to give the cord 12 thereof a desired pretension, as well as to delay its actuation when the lever is shifted, as will be more fully described hereinafter.
  • the pretension of the cord 12 is actually effected by a tension spring 7 positioned within the box 5, one end of the spring being supported on a closure in the end of the box 5, the closure having an orifice 8, and the other end of which is supported by an axially moveable gliding bolt 9.
  • the spring bears between the closure with the orifice 8 and the bolt 9 to which the cord is attached and from which it extends through the bore 11 of the closure with the orifice 8 and on to a compensating spring 14 to one end of which it is attached by means of a ring eye 13.
  • the other end of the spring 14 is connected by means of a further ring eye 15 to a continuation of the cord 12' which extends at least part way around the pulley or sheave 17 and is anchored thereto.
  • a second pulley or sheave 18 of larger diameter than the sheave 17 is attached to the same for rotation therewith about the shaft 21.
  • a further extension of the cord 12" is anchored in the slot 20 of the sheave l8 and is connected, by means of a ring coupling 23 and a ring eye 24, to a further extension thereof 12" and its ring eye 25.
  • the various coupling devices make possible decoupling of the respective cord parts l2, 12, 12'', 12" with considerable ease in cases of necessity such as where assembly and disassembly are required.
  • the traverse device is easily connected with the machine 1 by attaching the traverse bottom plate to the machine part 28 in advance of the bobbin 46, shown in winding position, and parallel to the longitudinal axis thereof.
  • Elements 27, 27' serve to fix the plate 30 on a machine part (not shown).
  • the cord 12" passes partially around a roller 32 arranged near one end of the bottom plate 30, and thence through a guide tube 33, 180 degrees around a roller 34 mounted at the other end of the plate 30 and to a carrier 35 to which the cord is connected by means of screws 36 and 37, 180 degrees around a further roller 38, through a second guide tube 39 and to the end of a spring 41 in the tube 39, the other end of which is attached to a pin fixed to the bottom plate 30.
  • a wire 44 is bent to provide two upright portions at the ends of a horizontal part, and this wire is supported by a bar 43 extending along parallel to the axis of the bobbins and in advance thereof in the machine direction so as to guide the yarn 29 to an oscillating wind-up thread guide 42, 42' traversing within the winding zone 47 of the bobbin body 46.
  • a holding bar 45 is positioned just in advance of the wind-up thread guide 42 and extends over the winding length of the bobbin 46 to hold the thread down when the winding procedure has been terminated and thus to position.
  • the bobbins are brought to rotation by means of a driving cylinder 48 against which they are pressed during wind-up; and the lateral part 50 of the bobbin 49, for example, is the transfer tail zone, the bobbin body portion therebetween, such as that indicated by the reference numeral 51, being the wind-up portion.
  • the traverse mechanism 26 can be exchanged for one which will bring the carrier 35 in the opposite direction so that a transfer tail may be formed on either the left or right hand side of a bobbin, as desired.
  • FIG. 1 shows the thread 29 during the winding procedure in central position, the thread 29' illustrated in broken lines in the left extreme position, and the traverse device 26 in the inactive position; and FIG. 2 illustrates the position of the respective parts at the moment of formation of a yarn reserve.
  • the new take-up tube 49 is already in winding position, and the full bobbin 46 is ready for doffing.
  • the formation of the yarn reserve is effected as follows.
  • the carrier 35 is actuated by the switch lever 4 moving in the direction of arrow A to effect the bobbin changing, and also shifting the spring box 5 to the position shown in FIG. 2 whereupon tension is placed on the cord 12, the spring 14 and the cord 12' to rotate the sheaves 17 and 18 about the shaft 21 and draw the cords 12" and 12" in the direction of the arrow C, thus to shift the carrier 35 to the left, as viewed, so that the yarn guide 35 moves more or less perpendicularly in respect of the direction of introduction of yarn into the machine after removal of the full bobbin 46 from contact with the driving cylinder 48 and the resulting, almost simultaneous removal of the yarn 29 from the yarn guide 42, to seize the yarn 29 held down by the bar 45 at any point within the traversing zone of the winding yarn guide 42.
  • the yarn is shifted by the hookshaped yarn guide 45' beyond the traverse zone and into the position indicated by the numeral 29" (FIG. 2) and, therefore, to a
  • the bobbin changing procedure has been approximately half completed, and the full bobbin 46 is in decelerating rotation winding up the yarn for a further short period of time.
  • the empty bobbin 49 passes thereafter to the driving cylinder 48 and commences rotation.
  • the transfer tail zone 50 of the empty coil 49 which is roughened, indented or flock-coated seizes the yarn 29', which action is favored by the decelerating bobbin 46 and automatically tears off the yarn by the change of direction of the yarn between the new take-up tube 49 and the full bobbin 46.
  • the switch lever 4 effecting bobbin changing is again brought into its original position. Simultaneously therewith, the carrier 35 with the hook-shaped yarn guide 35' shifts back to its original position (FIG. 1)
  • the compensating spring 14 permits completion of the traverse movement of the carrier. to the left as viewed, until it is stopped by contact with a stationary stop 31 and then, without undue strain on the cords, it permits further movement of the lever 4 until the spool changing procedure is completed.
  • a second stationary stop 31' serves to limit movement of the carrier to the right, as viewed.
  • the apparatus of the present invention contributes to the reduction of the loss of yarn arising by reason of the formation of a transfer tail in that small amounts of yarn are fed continuously during the short switching time necessary for bobbin changeover and that thread suction or other handling devices are eliminated along with manual operations between the rotating parts of the machine, wherefore the latent danger of accident to personnel is reduced.
  • Apparatus for the automatic formation during continuous yarn delivery of a transfer tail in a transfer tail zone adjacent a winding zone on a bobbin said apparatus having a frame-like bobbin support which is rotatable to bring bobbins mounted thereon successively into and out of engagement with a bobbin driving element, a switching hub in rotatable driving engagement with said bobbin support for rotating same to shift said bobbins relatively to said driving element, characterized by a traverse device having guide means extending across the whole of the transfer tail zone as well as the winding zone of a bobbin, a carrier mounted on and slidable relative to said guide means, cord drive means connected between said switching hub and said carrier for producing carrier movement when the switching hub is rotated, a yarn guide moveable with said carrier for receiving a yarn during bobbin changing and shifting the yarn from the winding zone into the transfer tail zone situated selectively in one of the two peripheral end zones of the empty bobbin, said cord drive means comprising a cord and a pretension spring interconnected
  • the traverse device comprises two rigid stop members arranged at the end zones of the same for supporting the tubes and for limitation of the traversing movement of the carrier.
  • cord drive means for said carrier is connected to the switching hub by means of a spring box fixed in the latter with pretension spring supkported therein and against a sliding bolt for receiving e end of the cord and against a closure with a bore through which the cord passes.
  • stop means are provided to limit the movement of said carrier and the drive means includes a compensating spring to allow further extension of said mechanism after said carrier movement is stopped by said stop means.
  • Apparatus according to claim 3 wherein a spring is supported in one of said tubes and extends between a pin and the drive means for moving the carrier from the transfer tail zone of the take-up tube against one of the stop members after spool changing has been terminated.
  • said guide means comprises a pair of tubes extending parallel to the longitudinal axis of said bobbins and extending across the winding zone and transfer tail zone I thereof, said cord being mounted to extend along a path parallel to said tubes.
  • stop means are provided to limit movement of said carrier and said cord drive mechanism includes spring means wherefore, when further movement of said carrier is prevented by said stop means, said lever may be further shifted to complete bobbin changeover without over tensioning said cord drive mechanism.
