Definitions

  • the invention relates to a device for inserting the thread into the catch slot of an empty bobbin tube according to the preamble of claim 1.
  • the incoming thread In automatic bobbins on which the bobbins are mounted on a rotating turret, the incoming thread must be transferred from the full bobbin to the catch slot of an empty tube without interruption and be caught by the catch slot before the thread is separated from the full bobbin.
  • the incoming thread is fed directly to the bobbin surface by the thread guide or indirectly via the drive roller during the winding process.
  • the empty bobbin tube gets into this thread run.
  • GB-A-2015046 has a thread guide rod attached to the turret, which is rotated together with the bobbins when changing the bobbin and gets into the thread path between the empty and full bobbins.
  • a slot arranged on the thread guide rod causes a deflection and thus relocation of the incoming thread into the area of the thread catching slot on the empty tube.
  • the thread guide rod which is firmly attached to the turret, inevitably enters the thread run when the turret is turned. It is not possible to determine the location, the time and the course of the axial displacement of the thread independently of the angle of rotation of the turret.
  • the invention has for its main object to provide a device in which the axial displacement of the thread between the full bobbin and the empty tube to form a thread bead on the full bobbin and for inserting the incoming thread into the catch slot of the empty tube independently of the rotational position of the revolver can take place.
  • the device according to the invention it is possible to move the incoming thread within a plane that is essentially perpendicular to the axis of rotation of the bobbin spindles above the empty sleeve to the catch slot and at the same time to keep the thread that is still running to the full bobbin to form a bead axially immovable.
  • the incoming thread can be guided twice axially over the catch slot by the device, so that it is ensured that the thread, if it is exceptionally not detected when the catch slot overflows for the first time, is clamped and entrained in the second overflow.
  • FIG. 1 shows an automatic winder with two winding mandrels 3 and 5 mounted on a turret, a thread laying device 7 of known construction and the machine housing 9, which contains the drive motors for the winding mandrel 3, 5, laying device 7 and the other units and parts of the control .
  • the turret carrying the two mandrels 3 and 5 is not shown and has a known construction.
  • the two bobbin mandrels 3 and 5 are overhung, which means that empty tubes 11 can be loaded or the full bobbins 13 can be removed by hand or by an automatic doffer.
  • a thread guide plate 15 is arranged above the bobbin mandrel 3 with the empty sleeve 11, which is swiveled upward by rotating the revolver, and which during the bobbin changing process removes the incoming thread 17 from the thread path X shown in broken lines in FIG. 2, which runs in an imaginary plane perpendicular to the axes of rotation A and C of the bobbin mandrels 3 and 5, is deflected in the direction of the arrow D into a yarn path Y which enables the yarn to be taken over by the empty bobbin 11.
  • a circumferential thread catch slot 19 is provided in the sleeve 11.
  • a thread guide plate 21 is pivotally or displaceably mounted on the housing 23 receiving the thread laying device 7 such that its front edge 25 deflects the thread 17 between the two bobbin spindles 3 and 5.
  • FIG. 5 the thread path when the thread guide plate 21 is pivoted in is shown in a dash-dotted line and in a solid line after the retraction.
  • An essentially V-shaped incision 27 is made on the thread guide plate, in which one leg is designed as an arcuate curve 29. The formation of curve 29 is explained in more detail with reference to FIG. 3.
  • a thread driver 31 is inserted in the thread guide plate 21 and is displaceable perpendicularly to its front edge 25.
  • the thread driver 31 is fastened to a slider 35 guided in a groove 33 and has a driver hook 36 which is at an angle of less than 90 ° to the lower surface of the thread guide plate 21 and points away from the incision 27.
  • the thread guide plate 21 consists of two sheet metal parts 37 and 39 which are arranged at a short distance from one another and form a box profile (FIGS. 3 and 4).
  • the groove 33 is inserted, which serves to guide the slider 35.
  • the slider 35 can be T-shaped (Fig. 4); or two guide bolts 41 penetrating the groove 33 can be attached to the slider 35, one of which can be designed as a thread driver hook 36.
  • a cable or rope 43 is attached to the slider 35, which leads to a deflection roller 45 which is arranged in the area of the rear edge 47 inside the thread guide plate 21. From the roll 45, the rope 43 either leads to a pulling device or ends outside the thread guide plate 21, for example in a loop 49 which can be gripped by hand.
  • An actuating lever 51 which is pivotably mounted on an axis E is in contact with the rear end of the slider 35 and is by means of a Spring 53 pressed against this.
  • the full spool 13 and the empty sleeve are pivoted by the turret by approximately 180 °.
  • the surface of the empty sleeve 11 comes into contact with the thread 17, which is still fed to the full bobbin 13. So that a thread bead 55 can be formed there, the thread guide plate 15 pivoted into the thread path Y holds the thread Thread 17 axially immovably tight.
  • the thread guide plate 21 is advanced or pivoted in such a way that its front edge 25 deflects the thread 17 between the surface of the sleeve 11 and the full bobbin 13.
  • the thread 17 passes under the thread driver hook 36 and is guided by it in such a way that the thread 17 running towards the thread bead runs in the imaginary plane perpendicular to the axis C. So that the incoming thread 17 can be gripped by the thread catch slot 19 on the empty sleeve 11, the thread guide plate 15 is pushed axially to the right until its guide slot 16 comes to lie in the plane through the thread catch slot 19. Simultaneously with the displacement of the thread guide plate 15, the thread driver 31 is pulled back by the rope 43 under the thread guide plate 21 in the direction of the arrow F.
  • the bottom 59 of the incision 27 is located approximately in the plane through the thread catching slot 19.
  • the formation of the thread bead 55 on the full sleeve 13 continues undisturbed, since the incoming thread 17, although this has been deflected to the right by the curve, is always held in the imaginary plane by the thread bead 55 by the thread driver hook 36 becomes.
  • the thread driver 31 can be actuated by pulling the loop 49 by hand; or an electric drive for the pull on the rope 43 can be provided.
  • the spring 53 is tensioned, which after the rope 43 has been released lets the thread driver 31 return to the starting position.
  • the thread is passed over the thread catch slot 19, he clamped by this and wound on the sleeve 11.
  • the thread section leading to the full bobbin 13 tears by itself, or it is separated with a corresponding cutting device.
  • the thread guide plate 15 can return to the starting position and transfer the thread 17 to the thread laying device 7.
  • the invention therefore relates to a changing system for thread positioning in bobbins during the changing process in an automatic winder, in which two bobbin spindles are stored and can be driven, in which a change takes place after the construction of a full package, the thread to be wound from the full package onto the Catch slot of an empty tube is redirected.
  • two guide means are provided for deflecting the thread, one guide means being axially displaceable and the second guide means displacing the thread axially with respect to the bobbin mandrel axis in connection with a suitable traction means.
  • a lifting plate is provided which removes the thread from a traversing device, the thread being positionable by axial displacement from the sliding plate.
  • the interchangeable plate is equipped with retraction hooks through which the thread can be steered via a curved path.
  • the deflection, on the one hand, via the sliding plate and, on the other hand, via the interchangeable plate, makes it possible to avoid having to use complex devices for producing a relative movement of the coil mandrels.
  • a particularly structurally simple solution is that the retraction hooks can be actuated via a cable pull.
  • these hooks are set in motion by means of motor drives.
  • the interchangeable plate takes on a second function: after the turret has been rotated, the interchangeable plate can be positioned between the full pack and the new pack, so that it is largely excluded that the separated thread end is wound into the new, running pack.
