Definitions

  • the invention relates to a device for simultaneous winding of several threads according to the preamble of claim 1.
  • the guide for the thread guide is designed as a swivel bar.
  • the feed thread guides can be moved from the threading position into the feed position without the continuous threads touching the sleeves.
  • the threads are brought into contact with the sleeves by lowering the swivel bar. Since it is extremely difficult to bring the feed thread guides exactly in front of the corresponding catch slots, it is recommended in this publication to first move the threads a little beyond the catch slots and then to lead them back again.
  • each thread is gripped by the associated catch slot, especially since the threads - due to the arrangement of the fixed inlet thread guides - do not run exactly in the planes of the assigned catch slots when they are put on, but rather at an angle. For thicker threads with a total denier of more than about 500 den, it is uncertain whether they will tear in the catch slots of the sleeves.
  • a rail which can be displaced parallel to the bobbin mandrel axis and on which thread guide pins are fastened is provided for the frontal insertion of a plurality of threads.
  • the device has an auxiliary element with a plurality of thread guide elements which can be pivoted independently of one another about a common axis.
  • Each thread guide element consists essentially of a thin rod, at the free end of which a thread guide sits.
  • the individual thread guide elements are released one after the other by the displacement of the rail, which is provided with a step-like control contour, so that they are pivoted into an intermediate position under the action of springs, whereby they take over the threads. Finally, by pivoting all the thread guide elements together, the threads are inserted into the catch slots of the individual bobbin tubes.
  • DE-A-3 136 908 describes a device which is similar to the first-mentioned device in terms of the essential features in the present context.
  • this document also mentions the feature that the inlet thread guides can also be moved and positioned along an overhanging arm. In particular, they can either be brought into a first position, in which they are close together at the end of the arm, or in a second position, in which they are located centrally above the winding units.
  • the invention has for its object to provide with simple means a device of the type specified in the preamble of claim 1, in which the application process takes place exactly and without problems.
  • the auxiliary organ according to the invention fulfills a double function: Despite any positional deviations of the feed thread guides, it ensures exact positioning of the threads in front of the catch slots of the individual sleeves.
  • the second function of the auxiliary organ is that with its help the threads to be applied are moved in the direction of the sleeves and brought to bear against the sleeves; pivoting of the guide is therefore unnecessary.
  • the feature of claim 3 facilitates threading into the inlet thread guides and in particular ensures that the threads run exactly in the planes of the catch slots when they are put on.
  • the feature of claim 4 ensures a safe separation after application even with stronger threads.
  • a cantilevered mandrel 2, a driving roller 3 and a traversing device 4 can be seen on a machine housing 1 in a known arrangement.
  • Several sleeves 5a - 5d are seated close to each other on the mandrel 2, each of which has a revolving one in the vicinity of the end on the left in FIG Has catch slot.
  • the traversing device 4 has a plurality of traversing thread guides 6.
  • the deflection flap 7 can be folded pneumatically from an approximately vertical basic position into an inclined position shown in FIG. 2.
  • a guide tube 8 for a plurality of feed thread guides 9a-9d is connected immovably to the machine frame at an angle underneath the spool mandrel 2 the.
  • the guide tube 8 is provided on its side facing the spool mandrel 2 with a longitudinal slot 10.
  • the feed thread guides 9a-9d protrude in an approximately horizontal direction. They are inside the guide tube 8 with a linkage - such as. B. in DE-PS-2 627 643 - connected, which makes it possible to bring the thread guide 9a - 9d with the help of a handle 11 either in a threading position A or in a feed position B.
  • inlet thread guides 12a-12d are attached, which can be moved on a stationary guide rail 13 similar to the thread guide 9a-9d parallel to the axis of the bobbin mandrel 2 into a threading position A and a positioning position B;
  • a working position C is provided, in which each thread guide 12a-12d is located exactly above the center of the assigned traversing area.
  • a pneumatic cylinder (not shown), which is coupled to the pneumatics of the deflection flap 7, is provided for displacing the inlet thread guides 12a-12d.
  • a feed flap 14 is provided as an inherently rigid auxiliary element for the exact simultaneous application of several threads 24a-24d. It can be pivoted about the axis of the guide tube 8 from a supply (for application) to an end position (after the application process). In the provision, which is indicated by broken lines in FIG. 6 and provided with the reference symbol 14 ', it is folded up almost vertically. The end position drawn with solid lines in FIG. 6 is almost horizontal, with a slight inclination towards the front.
  • a pneumatic cylinder 15 is accommodated in the guide tube 8 at the end on the housing, to whose piston rod 16 a driver 17 is fastened. On the driver 17 there are bolts 18 which, as can be seen in FIG. 4, engage in oblique grooves 19 of a bushing 20 through recesses in the guide tube 8. This sits rotatably, but cannot be moved in the axial direction, on the guide tube 8.
  • the bush 20 forms a rigid unit with the contact flap 14.
  • the contact flap 14 consists essentially of several levers 21 and a strip-shaped thread guide plate 22 which is screwed onto the levers 21.
  • the thread guide plate 22 is provided with a plurality of thread guide stones 23a-23d, which are fastened in funnel-like recesses.
  • Each thread guide block 23a-23d lies with its slot immovably exactly in the plane of the catch slot of the associated sleeve 5a-5d.
  • the envisaged number of sleeves 5a - 5d - in the present case four - is slipped onto the mandrel 2.
  • the drive motor is switched on and the drive roller 3 is lowered to the contact with the sleeves 5.
  • the inlet thread guides 12a-12d arranged above the machine are brought into the threading position A, just like the thread guide 9a-9d.
  • the deflection flap 7 is folded over from the vertical basic position into the deflection position shown in FIG.
  • the flap 14 is pivoted into the almost vertical provision 14 '.
  • the threads 24a-24d coming from a spinning shaft are picked up with a conventional feed injector 25 and inserted into the inlet thread guides 12a-12d.
  • the inlet thread guides 12b-12d are shifted into the feed position B; for the entry guide 12a, the feed position coincides with the threading position.
  • the threads 24a-24d are now guided with the aid of the feed injector 25 between the drive roller 3 and the traversing device 4 from the operating side and are threaded into the feed thread guides 9a-9d.
  • the deflection flap 7 prevents the threads from being caught by the traversing thread guides 6. Because of the laterally offset arrangement of the guide tube 8 relative to the spool mandrel, the threads 24a-24d do not initially touch the sleeves 5a-5d.
  • the thread guides 9b - 9d are shifted into the feed position B. For the feed thread guide 9a, the feed position corresponds to the threading position.
  • the threads then run - apart from any slight inaccuracies in the positioning of the thread guides 9b - 9d - in the planes of the catch slots of the sleeves 5a - 5d.
  • the catch slots are not recognizable in FIG. 1, since the corresponding lines coincide exactly with the lines which represent the threads 24a-24d running vertically.
  • the feed flap 14 is pivoted into the end position. Its front edge, on which the thread guide stones 23a - 23d are attached, comes into contact with the threads 24a - 24d. The threads slide over the edges of the funnel-shaped recesses into the slots of the thread guide stones 23a-23d. Any minor lateral deviations of the thread run from the prescribed position are thereby corrected. Shortly before the feed flap 14 reaches its end position, the threads are gripped by the catch slots of the sleeves 5a-5d, tear off and are spun up in the area of the catch slots to form a knot wrap. Now the deflector 7 is pivoted back into the basic position, and at the same time the inlet thread guides 12 are moved into the working position C. As a result, every thread begins to become rich to move to the center of the associated traversing area. It is automatically detected by the corresponding traversing thread guide 6. The coil buildup begins.
  • the exemplary embodiment illustrated in FIGS. 7-9 essentially differs from the exemplary embodiment described so far by a modified design of the feed flap, specifically by the attachment of a cutting device for multifilament threads for a total titer greater than 500 dtex. However, it is also recommended for a monofilament thread under 500 dtex and for tubes that are used more often, since the latter no longer have their original structure.
  • the feed flap 31 is provided on its front edge with strips protruding at right angles with slide shoes 32 which point (with the feed flap 31 in a vertical position) in the direction of the spool mandrel 2.
  • Thread guide blocks 34 provided with thread guide slots 33 sit in the slide shoes 32.
  • Each thread guide block is movable within its slide shoe 32 along a stroke path and is resiliently supported by a spring 35.
  • two inclined knives 37, 38 are fastened in a holder 36, the shape and size of which corresponds approximately to the slide shoe 32, the cutting edge of which - when looking through the associated thread guide slot 33 in the direction of the pivot axis of the contact flap 31 - cross the stroke of the thread guide block 34 made possible by the spring 35 and together form a V.
  • the flap 31 pivots up to the maximum end position 31 ".
  • the contact flap 41 has a base body 42, on the front edge of which two thread guide plates 43, 44, which are arranged in a mirror-symmetrical manner and have a tubular clamp profile, are fastened. These are provided with thread guide slots 45 on their free edges.
  • the two half-shell-like configurations of the thread guide plates 43, 44 comprise a tube 46 which has a longitudinal slot on the side facing the thread guide slots 45.
  • a rod 47 is guided in the tube 46 and is equipped with obliquely positioned knives 48 in accordance with the number and arrangement of the thread guide slots.
  • the knives 48 protruding through the slot of the tube 46 are covered on both sides by the flat edge strips of the profiled thread guide plates 43, 44.
  • a cap 49 On the protruding end of the tube 46 facing the machine housing is a cap 49, which serves as an abutment for a coil spring 50. This presses with its other end against a thickening of the rod 47, so that it bears against a stop 51 in the position shown in FIGS. 10 and 11 on the operator-side end of the tube 46.
  • a pulling rope 53 is fastened to the end of the rod 47 protruding from the cap 49 by means of a holder 52.
  • This runs over a roller 54, which is mounted on a bracket 55 attached to the feed flap 41, and is guided tangentially from there via a bushing 56 to a cross member 57, which is fixedly connected to the machine frame 1, and is fastened to it with a screw 58.
  • the socket 56 corresponds to the socket 20 mentioned in connection with the first exemplary embodiment.
  • the pulling rope 53 automatically pulls the rod 47 in the direction of the roller 54 in the sense symbolized by the arrow 59 in FIG. 11 when the contact flap 41 is pivoted.
  • the knife 48 moves with it Dashed lines indicated position 48 '. It passes the thread guide slot 45 and cuts the thread therein.
  • the movement of the rod 47 can also be done in other ways, for. B. by a pneumatic cylinder. It is then triggered by the flap using a limit switch.
