Definitions

  • a device according to the preamble of claim 1 is known from German Offenlegungsschrift 26 27 643.
  • the threads supplied by a thread guide or a delivery system are taken over by means of a manual thread suction device, then on a thread guide rod on the front side of the winding device by means of guide notches together as a bundle, but guided separately from one another. Subsequently, when the threads are simultaneously moved through the insertion gap of the winding device, these are moved from one another to the one corresponding to the distance corresponding to the arranged in a row of bobbin tubes by means of the thread eyelets movable along the supporting axis of the bobbin tubes.
  • a swivel bar carrying the thread eyelets is pivoted against or under the bobbin sleeves for the simultaneous insertion of the threads into the catch slots of the sleeves.
  • the threads are lifted out of the guide notches of the thread guide rod so that they can move freely along the thread guide rod into the position corresponding to the thread tension.
  • the thread eyelets are moved by displaceable disks which carry the thread eyelets and are mounted on a rotatable threaded spindle.
  • One of the washers is provided with an internal thread and is moved as a nut (hereinafter referred to as the nut washer) by the rotating threaded spindle.
  • the remaining disks are slidably arranged on the spindle and connected to one another by driver rods.
  • the disadvantages of the device are that the possible inaccuracy of the disk perspective of the thread positions in front of the corresponding catch slot has to be compensated for by an additional movement parallel to the axis of the bobbin mandrel in order to be sure that each thread is actually caught by the catch slot.
  • the possible inaccuracy arises on the one hand from the imprecise positioning of the nut washer due to the speed of the motor-driven spindle and on the other hand from the possibility that the friction between the drive rod and the washer can be greater than that between the spindle and the washer.
  • a friction roller 3 and a spool mandrel 4 are rotatably mounted (not shown).
  • the spool mandrel 4 can be moved from a moved-away position (rest position) (FIG. 1) to a raised position (working position) and back.
  • a first thread guide bar 8 is slidably arranged (partially shown).
  • the displacement directions 9a and 9b (FIG. 5) are given by the guide bolts 10 fastened in the support 7 and by the guide slots 68 provided in the guide bar 8 and interacting with the guide bolts 10.
  • the displacement takes place in one direction 9a by means of a pneumatic piston 11, the cylinder 12 of which is attached to the support 7 (not shown), and in the other direction 9b by means of a tension spring 13.
  • the tension spring 13 is between a support part 7a and the guide bar 8 clamped.
  • the piston head 14 of the piston 11 bears against the end face 15 of the guide bar 8.
  • a second guide bar 16 is pivotally and slidably mounted by means of a bearing block 17 fastened to the support part 7b and a shaft 22 which is rotatably and displaceably mounted therein and which is connected to the guide bar 8.
  • the combined pivoting and shifting movement, or swirl movement of the guide bar 16 is made possible by the swirl movement of a grooved roller 20 firmly connected to the shaft 22, in which a sliding block 24 connected to a support part 7c engages in a groove 23 of the grooved roller 20.
  • the swirl movement of the guide bar 16 from a working position (FIG. 4) into an initial position R (FIG. 4) is caused by the tensioning force of a spring 21 located between the bearing block 17 and the grooved roller 20.
  • the guide bar 16 makes a backward movement in the direction of the pneumatic cylinder 19 when changing from the working position to the rest position.
  • the piston head 26 rests on an end face 25 of the grooved roller 20 opposite the spring 21.
  • the thread guide bar 16 has four guide notches 27a, 27b, 27c and 27d at equal intervals A. These distances correspond to the mutual distances between the catch slots 6 of the sleeves 5 clamped on the mandrel 4.
  • traversing devices 28 shown in FIG. 2 with the traversing thread guides 29 (FIG. 4), which in their traversing area in a manner known per se are the thread for winding formation the coil sleeve back and forth, arranged.
  • This device 30 comprises a shaft 31 which is rotatably supported on the one hand in a bearing 32 embedded in the housing part 1a and in a bearing 33 recessed in the support part 7d.
  • the shaft 31 is provided with a collar 34 abutting the end face of the bearing 32 and the bearing 33 is provided with a bearing cover 35 abutting the end face of the shaft 31.
  • Carrier elements 36a to 36d are slidably provided on the shaft 31.
  • a driver 38 of a pneumatic piston 39 engages in a recess 37 of the carrier element 36a.
  • a driver rod 41 is fixed to the carrier element 36a and connected to the carrier element 36b in a friction-locked manner.
  • the carrier element 36c likewise has a driver rod 42 which is fixedly connected to it and frictionally connected to the carrier element 360.
  • a driver rod 43 which is fixedly connected to the carrier element 36d is frictionally connected to the carrier element 36c. “Frictional connection” should be understood to mean sliding friction of great tolerance.
  • Each thread guide rod 44 is fastened to the corresponding carrier element 36a, 36b, 36c and 36d and carries a thread guide 45 (FIGS. 4, 6 and 12).
  • a thread guide edge 46 with a second thread guide edge 46a of a finger 47 forms a guide notch 67 with an angle a of 90 °; while with a thread guide 48 (FIG. 13), which can be selected as a variant for the thread guide 45, the guide notch 67 has an angle 9 of less than 90 °, e.g. B. of 60 °. The use of this variant will be mentioned later.
  • the carrier elements 36a to 36d, the thread guide rods 44 and the thread guide 45 together form the thread guide elements 51a, 51b, 51c and 51d.
  • the shaft 31 has a longitudinal groove 49 for frictionally receiving the slot nuts 50 fastened in the corresponding carrier elements 36a, 36b, 36c and 36d.
  • the thread guide elements 51a-d are pivoted when the shaft 31 is rotated.
  • a slide pin 52 (FIG. 6) is fastened in the support part 7d and serves for frictionally receiving a driver 53, which in turn engages in a groove 54 of the carrier element 36d with a friction fit.
  • a stop 55 at the end of the sliding bolt 52 is used with the aid of the driver 53 to limit the axial movement of the carrier element 36d.
  • a tension spring 56 is clamped between the support part 7d and the driver 53.
  • a crank mechanism (FIGS. 6 and 11) is used to rotate the shaft 31, consisting of a two-stage pneumatic cylinder 58 (not shown) pivotably arranged on a housing part 1b, a hinge pin 60 for the power transmission between a hinge part 61 and fixed to the piston end a joint part 63 fastened to the shaft end 62 of the shaft 31.
  • threads 64a, 64b, 64c and 64d are shown with reference to FIGS. 1 and 4 and takes place as follows:
  • Threads 64a-d coming from thread guides 65 or a delivery mechanism (not shown) are so-called by means of a so-called suction gun 66 or a functionally equivalent suction device, e.g. B. an automatic suction device (not shown), to the brought into the working position (shown in Fig. 4 with a solid line) first thread guide 8 and in the thread guide 45, respectively guide notches 67, out.
  • suction gun 66 or a functionally equivalent suction device, e.g. B. an automatic suction device (not shown) to the brought into the working position (shown in Fig. 4 with a solid line) first thread guide 8 and in the thread guide 45, respectively guide notches 67, out.
  • the thread guides 65 form the apex of the traversing triangle and are arranged essentially perpendicularly above the center of the traversing area of each bobbin tube 5, as is indicated in FIG. 1 on a tube with the area C.
  • the thread guide elements 51a to 51d d were pivoted from an initial position D into a thread take-up position E by means of the first stage of the pneumatic cylinder 58 (FIGS. 4 and 6).
  • the threads 64a-d lie freely tensioned within the winding device between the notches 27a-d and the thread guides 45 next to the traversing area C and exactly in front of the corresponding ones Catch slots 6 and substantially parallel to them.
  • the spring 56 retains the carrier element 36d until the other three carrier elements have reached their spacing from one another given by the stops 41a, 42a or 43a. In this way, the thread 64d still resting on the bar 8 does not slide over the notch 27d even when e.g. B. the friction between the carrier element and the driving rod would be greater than between the carrier element and the shaft 31.
  • the pneumatic cylinder 19 is relieved, so that the spring 21 moves the grooved roller 20 and thus the second thread guide strip 16 back to the starting position R.
  • the guide bar 16 is pivoted away from the thread path by means of the swirl movement mentioned.
  • the threads are guided through the notches 27a-d in such a way that some reserve turns are placed between the catch slot 6 and the traversing area C.
  • the threads 64 are stretched freely between the thread guides 65 and the sleeves 5, strive as a result of this thread tension in the traversing area C, and are gripped by the traversing thread guides 29. When the threads are gripped by the traversing thread guides 29, the normal winding process begins.
  • a further embodiment of the invention consists in that a thread deflection 69 is arranged (indicated by dashed lines in FIGS. 1 and 3) in such a way that threads 64a-d, bundled therein and guided on the first thread guide strip 8, as shown in FIG Thread guides 45 are detected when swiveling from position D (FIG. 4) to position E.
  • This embodiment offers the advantage that the threads 64 do not have to be placed individually in the corresponding thread guides 45 by hand, which results in a further simplification of the method and a further time saving.
  • the method described and the device can also be used for other thread catching devices which, in addition to the sleeves, e.g. B. on the mandrel itself are provided. Such devices replace the catch slots 6 mentioned.
  • Such a mandrel is z. B. from US-PS-4 106 711 and GB-PS-1 562 548 known.
  • the position of a surface 11 along the coil mandrel essentially corresponds to the position of a catch slot 6.
