Definitions

  • the invention relates to a method and a device for inserting at least two threads and the like into a winding device with a number of traversing devices arranged next to one another corresponding to the number of threads and an equal number of bobbin tubes located on a bobbin mandrel, each with a trapping agent.
  • the method further includes the features that the threads are taken over by a thread suction device and then brought to individual thread guides located above the winding device, then to a thread guide located above the traversing devices and further to individual thread guides below the traversing devices and thereby being moved outside the traversing area , then in each case by means of the corresponding thread guide located below the traversing devices, brought from a starting position at the outer end of the spool in front of the corresponding thread catching means and simultaneously guided into the catching means for simultaneous detection.
  • the device further includes the features that the thread catching means can be a catch slot, for example, and that the winding device with a thread guide bar above the traversing devices and per thread one thread guide located below the traversing devices, which from a starting position at the outer end of the spool in one direction of movement is parallel to the spool in an inner layer in which the thread is brought in front of the corresponding thread catcher, and is provided with means for moving the threads from the position in front of the thread catcher in the thread catcher.
  • the thread catching means can be a catch slot, for example, and that the winding device with a thread guide bar above the traversing devices and per thread one thread guide located below the traversing devices, which from a starting position at the outer end of the spool in one direction of movement is parallel to the spool in an inner layer in which the thread is brought in front of the corresponding thread catcher, and is provided with means for moving the threads from the position in front of the thread catcher in the thread catcher.
  • a device according to the preamble of claims 1 and 2 is known from German Offenlegungsschrift 26 27 643.
  • the threads delivered by a thread guide or a delivery unit are taken over by means of a thread suction device, then, together with a thread guide rod on the end face in front of the winding device, by means of guide notches, as a bundle, but separately from one another. Subsequently, with simultaneous movement of the threads through the insertion gap of the winding device, these threads are moved separately from one another by means of thread eyelets movable along the supporting axis of the bobbin tubes, at a distance corresponding to the bobbin tubes arranged in a row.
  • 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 disks or the thread positions in front of the 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.
  • the object of the invention is to remedy these disadvantages.
  • the invention as characterized in the claims, solves the task procedurally in such a way that when the threads are moved in front of the corresponding thread catching means, these are additionally taken up and above one another above the traversing devices by thread guides that can be moved into the thread path and, on the other hand, below the spool mandrel thereby, before the simultaneous grasping of the threads by the catching means, are held in an intermediate position, in which the threads lie exactly in front of the catching means, and that after the threads are grasped by the catching means, the thread guides located above the traversing devices are no longer in the thread path protrude so that the individual thread can be picked up again by the corresponding traversing device.
  • the device is characterized in that the thread guide bar can be moved from a rest position into a working position in which the threads lying thereon can no longer be grasped by the traversing devices, that below the guide bar, hereinafter referred to as the first guide bar, a second one provided with guide notches , from a rest position into a working position movable thread guide bar is provided, the number of notches of which corresponds to the number of threads to be wrung out, and in which the mutual spacing of the notches corresponds to the distances between the thread catching means, that furthermore the thread guides located below the traversing devices with a predetermined mutual A distance is arranged on an inner side of a guide means facing the bobbin mandrel such that the threads can be lifted off the thread catcher by the thread guides so that the means for moving the threads into the thread catcher show the threads are pivoting thread guides which can be pivoted from a starting position by means of a thread guide pivoting device in such a way that in a first pivoting stage they move
  • H. is prevented from taking over the thread assigned to it until the corresponding thread is gripped by the corresponding guide notch and is guided in front of the corresponding thread catching means in such a way that the thread is guided in front of the corresponding catching means essentially perpendicularly, as seen perpendicularly to the bobbin tube.
  • the guide means is a flat guide rail which can be displaced essentially parallel to the spool mandrel axis and which is provided with steps for releasing the pivotable thread guides into the first step, the end faces of which are at the same distance from one another as those on the inside arranged thread guides and that the pivotable thread guides have a length corresponding to the steps.
  • a friction roller and a winding mandrel 4 are rotatably mounted (not shown).
  • the spool mandrel 4 can be moved from a moved away position (rest position) (not shown) to a raised position (working position, FIGS. 2 and 2) and back.

  • a first thread guide bar 8 is slidably mounted in a support 7 fastened to the machine housing 1.
  • the displacement directions 9a and 9b (FIG. 4) are given by the interaction of guide bolts 10 fastened in the support 7 and guide slots 71 provided in the thread guide bar 8.
  • the displacement takes place in one direction 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 by means of a tension spring 13.
  • the tension spring 13 is clamped between a support part 7a and the guide bar 8.
  • the cylinder head 14 of the piston 11 bears against the end face 15 of the guide bar 8.
  • a second guide bar 16 is rotatably and displaceably mounted by means of a bearing block 17 fastened to a support part 7b.
  • the displacement in the forward direction takes place by means of a pneumatic piston 18, the cylinder 19 of which is fastened to the support 7 (not shown), and in the rearward direction by means of a compression spring 21 arranged between the bearing block 17 and a grooved roller 20.
  • the grooved roller 20 in turn is at one End connected to a shaft 22 to which the thread guide bar 16 is attached at the other end.

  • This device 30 comprises a shaft 31 which is within a. Hollow shaft 32 is rotatably mounted.
  • the hollow shaft 32 in turn is rotatably supported in a bearing 33 embedded in the housing part la (FIG. 5) and in a bearing 34 recessed in the support part 7d.
  • the axial fixation of the hollow shaft 32 takes place on the one hand by means of a shaft collar 37 which abuts the bearing 33 on the end face and on the other hand by means of a bearing cover 38 fastened in the support part 7d which abuts the hollow shaft 32 on the end face.
  • Thread guide elements 39a-d are pivotally arranged on the hollow shaft 32, each consisting of a bush 35 rotatably mounted on the hollow shaft 32 and a rod 40 fastened to it and thread guides 41 fastened to the rod 40.
  • a rod 40 belonging to the rod 40 and slightly angled to it (apparent from FIG. 8) rod extension 42, the free end is designed as a sliding block 43.
  • a helical spring 36 fastened on the one hand to the bush 35 and on the other hand to the hollow shaft 32 has the function of the bush 35 in the direction B (FIGS. 7 and 11), i. H. counterclockwise, seen from the free end of the bobbin mandrel, to thereby pivot the thread guide elements 39a-d in this direction.
  • the thread guide 41 has a thread guide notch 44 (FIG. 9), formed from the thread guide edges 45 and 46.
  • the thread guide edges 45 and 46 form an opening angle a of less than 90 °, e.g. B. an angle of 60 °.
  • a guide rail 48 (FIGS. 1, 3 and 10) which can be displaced essentially parallel to the coil mandrel axis.
  • This rail 48 is used to guide the thread guide elements 39a-d (FIG. 5) by means of the sliding block 43 and the threads 49a, 49b, 49c and 49d during the insertion of the threads into the winding machine.
  • the rail 48 is provided on the inside 50 facing the spool with thread guide pins 51, while the opposite outside 52 serves to guide the sliding shoes 43.
  • the rail on the upper narrow side 53 (FIG. 3) is provided with steps 54 such that the distance a between the step end face 54a and the guide pin 51 (FIG. 10a) is equal to or less than the sliding shoe width b (FIG. 9 ) is.
  • the division c (Fig. 10a), d. H. the distance from pin to pin 51, which corresponds to the distance between the end faces 54a, is selected such that when the threads 49a-d are introduced into the winding machine by means of the rail 48, at the moment the threads 49a-d are transferred from the first guide bar 8 to the second guide bar 16, the threads are guided on the guide bar 16 in such a way that each thread passes into its corresponding guide notch 27a-d when it continues to slide on the guide bar 16.
  • the corresponding position of the rail 48 is indicated in FIG. 1 with the dash-dotted representation of the threads 49a-d.
  • the rail 48 is connected by a driver 55 to the piston 56 of a pneumatic cylinder 57, which in turn is attached to the machine housing 1.
  • a crank mechanism 58 (FIGS. 5 and 6) consisting of a pneumatic cylinder 59, the cylinder rear side of which is pivotally connected to a housing part 1 b and a hinge pin 60 for the transmission of force between a hinge part 61 fastened to the piston end and a articulated part 63 fastened to shaft end 62 of shaft 31.

  • the guide rail was brought from the starting position shown in FIG. 3 into the working position shown in FIG. 1 by actuating the cylinder 57 (not described).
  • the shaft 31 (FIG. 5) is then rotated by actuating the cylinder 59 in such a way that the thread guide elements 39a-d are pivoted from the initial position D shown in FIG. 11 with a dotted line into the position Di shown with a broken line.
  • the pneumatic cylinder 57 begins to move the piston 56 and thus the guide rail 48 from the position shown in FIG. 1 to the position shown in FIG. Slightly delayed, namely when the bills 48 have reached the position of the threads shown in dash-dotted lines in FIG. 1, by relieving the cylinder 12 (FIG. 4), the first thread guide strip 8 is inclined in the direction 9b in the direction 9b by means of the tension spring 13 11, that the threads 49a to 49d on the second guide bar 16 do not yet come into contact with the guide notches 27a-d and continue to slide until each thread on the one still on the guide bar 16 path to be covered is stopped in the corresponding guide notch 27a to 27d, d. H. the thread 49a in the notch 27a, the thread 49b in the notch 27b, etc.
  • the spatial relationships between the sliding shoe 43 and the thread guide 41 are such that when the sliding shoe 43 swivels over the corresponding step, the leading edge 46 (FIG. 9) is already in front of the thread, in the direction of view of the spool axis and from the free End of the bobbin seen here before the shoe 43 (Fig. 11) pushes the thread away from the guide pin 51.
  • the distance between the end face 43a (Fig. 8) of the sliding block and the thread is therefore larger than the distance between the thread and the fingertip 46a.
  • the rod extension 42 must be essentially parallel to the outside 52 of the rail 48 with the same length of all sliding shoes 43.
  • the distance m shown in FIG. 9 must be greater than the distance a shown in FIG. 10a.
  • the threads 49a-d lie freely tensioned within the winding device between the notches 27a-d and the thread guides 41 next to the traversing area C and exactly in front of the corresponding one Fishing gear and essentially parallel to it.
  • the cylinder 59 continues to be pressurized in the same sense, but is prevented from moving further by said abutment of the driving mandrel 47 in the guide slot 72.
  • the stroke of the cylinder 65 is adapted to the pivoting movement of the thread guides 41 between the positions E and F.
  • the stroke of the cylinder 59 is such that the thread guides can be pivoted between positions D and F.
  • the force of the cylinder 59 is dimensioned such that the positions, D, E and F of the stroke and force of the cylinder 65 are given.
  • the pneumatic cylinder 19 (FIG. 5) is relieved.
  • the spring 21 displaces the grooved roller 20 and thus the second thread guide strip 16 back into the starting position.
  • the guide bar 16 is rotated at the same time and pivots the notches 27a-d out of the thread path.
  • the threads 49a-d are now freely stretched between the thread guides 70a-d and the sleeves 5 and, as a result of this thread tension, strive in the traversing area C, in which they are gripped by the traversing thread guides 29.
  • This variant consists in that instead of the bush 35 (FIG. 5) and the coil spring 36, a coil spring 75 is connected on the one hand to the rod 40 and on the other hand to a bolt 76 anchored in the shaft 31.
  • the remaining elements in connection with the rod 40 are those already described and accordingly have the same designations.
  • a trough-shaped stop 77 serving to receive the elements 75, 76 and 40 prevents the coil spring 75 from bending in this direction.
  • the stop 77 with its end adjoining the shaft 31, is guided in the guide slot 73 in such a frictional manner that axial displacements of the shaft 31 are thereby prevented.
  • the thread guide element 79 (FIG. 20) consists of a thread guide 80 fastened to a rod 40a with a thread guide notch 81, formed from a long finger 82 and a short finger 83.
  • the rod 40a can be fastened analogously to the rod 40 at the same location on the bush 35.
  • the end face 84 When the rail 48 moves back into the starting position, the end face 84 first slides on the outside 52 and then transfers the guidance to the short finger 83 when pivoting via the corresponding step 54.
  • the lengths of the two fingers 82 and 83 are selected such that, after the long finger 82 lies above the step 54, the end face 84 has not yet reached the inside 50, i. H. the thread 49d passes the finger 82.
  • Variant B can also be combined with variant A.
  • the method described and the device can also be used for other thread catching devices, which in addition to the sleeves z. B. are provided on the mandrel itself. Such devices replace the aforementioned catch slots 6.
