Definitions

  • the invention relates to a method and a device for introducing threads and the like into a winding device with at least two traversing devices arranged axially next to one another and associated spool sleeves located on a spool.
  • the method also includes the features that each thread coming from a thread guide above the winding device is taken over by a thread suction device and then placed on a thread guide above and on individual thread guides below the traversing device and guided outside the traversing area, and that the threads are guided by means of the lower thread guide are moved from a starting position at the outer end of the bobbin mandrel in front of the corresponding bobbin tubes such that each thread is brought into an area in front of a thread-catching means of the corresponding bobbin tubes and then, for simultaneous detection of all threads, these are simultaneously guided into the catching means and then wound up.
  • the device further includes the features that a thread catcher is assigned to each of the bobbin tubes, and that the winding device includes a thread guide bar above the traversing device and, for each thread, a thread guide which can be moved from the starting position at the outer end of the spool along the bobbin tubes and can be pivoted against the bobbin tubes, which is connected to a carrier element and the carrier elements are connected to one another by means of driver rods with stops, and that the innermost support element closest to the bearing side of the coil mandrel is driven.
  • the threads delivered by a thread guide or a delivery system are taken over by means of a manual thread suction device, then connected to a thread guide rod on the front side in front of the winding device by means of guide notches together as a bundle, but 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 or thread positions in front of the corresponding catch slot must 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.
  • Another disadvantage of the method is that the threads are first guided as a bundle (on the guide rod) on the front side in front of the winding device and only released again when the threads are introduced in front of the bobbin tubes (by means of thread, spindle and washers).
  • the invention achieves the object in a winding device with at least two axially arranged traversing devices and associated bobbin sleeves located on a bobbin in such a way that the threads after the application to the in the starting position at the outer end the thread guide located in the bobbin take a stretched position between the thread guides above the winding device and the thread guides, and that they are grasped by a guide bar provided above the bobbin tube with guide notches while moving in front of the catching means in such a way that they end at the end of the movement the fishing gear comes in front of it.
  • a friction roller 3 and a spool mandrel 4 are rotatably mounted (not shown).
  • the bobbin mandrel 4 can be moved from a moved away position (rest position) (FIG. 1) to a raised position (working position) and back.
  • a catch slot 6 is provided on the bobbin tubes 5 for clamping a thread 64a-d caught therein.
  • 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 displaceably 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) in an initial position R (FIG. 4) is created 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 inserted on the one hand in a bearing 32 embedded in the housing part la and in a support part 7d let bearing 33 is rotatably mounted.
  • 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 36 a.
  • 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 36b.
  • a driver rod 43 which is fixedly connected to the carrier element 36d is frictionally connected to the carrier element 36c.
  • “Frictionally connected” is to 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).
  • 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 fastened to the piston end and a articulated part 63 fastened to shaft end 62 of 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 are sucked in by means of a so-called suction gun 66 or a functionally equivalent suction device, for example an automatic suction device (not shown), to the first thread guide bar 8 brought into the working position (shown in solid lines in FIG. 4) and in the thread guide 45 or guide notches 67, respectively.
  • the thread guides 65 form the apex of the traversing triangle and are arranged substantially perpendicularly above the center of the traversing region of each bobbin tube 5, as is indicated in FIG. 1 on a tube with the region C.
  • the thread guide elements 51a to 51d were pivoted from a starting 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 pneumatic cylinder 40 (FIG. 6) begins to move the piston 39 and thus the thread guide elements 51a-d from the initial position shown in FIG. 1 to the position shown in FIG. 3. Slightly delayed by relieving the load on the cylinder 12 (FIG. 5), the first thread guide bar 8 is moved back to the starting position B in the direction 9b by means of the tension spring 13, so that the threads 64a to 64d come to rest on the second guide bar 16. Each thread is stopped on its path still to be covered on this guide bar in the corresponding guide notch 27a to 27d, i.e. the thread 64a in the notch 27a, the thread 64b in the notch 27b, etc.
  • 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 if e.g. the friction between the carrier element and the driving rod would be greater than between the carrier element and the shaft 31.
  • 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 described method and the device can also be used for other thread catching devices which, in addition to the sleeves, e.g. on the mandrel itself. Such devices replace the aforementioned catch slots 6.
  • Such a coil mandrel is e.g. known from US-PS 4 106 711 and GB-PS 1 562 548.
  • the third phase proceeds as follows with the bobbin mandrel with the conical thread guide surface 11 and the teeth 12 shown in the above-mentioned patents:
  • the thread guide elements 51a-d bring the corresponding thread 64a-d to the corresponding surface 11 when pivoted into the position F. Due to the existing thread tension generated by the suction gun, the thread slides on the surface 11 into the area of the teeth 12 and becomes like described, recorded and cut off in the patent specifications.
  • the position of a surface 11 along the coil mandrel essentially corresponds to the position of a catch slot 6.
