Definitions

  • the invention relates to a winding machine for winding a plurality of threads to form cross-wound bobbins with a wing traversing. Preamble of claim 1.
  • Such a winding machine is particularly suitable for continuously starting threads, in particular synthetic threads, which start up and are wound up at speeds of more than 6,000 m / min.
  • Such cross-winding devices are provided according to the Swiss Patent 424571 equivalent to US Patent 3,374,961 for each one of several winding apparatus with adjacent Changierhub Symposiumen, wherein the distance of the adjacent Changierhub Symposiume 'is such that an overlap of the rotational circle of the co-rotating and arranged in different planes of rotation driver arms of the neighboring traversing devices takes place.
  • the axial distance between the traversing stroke ranges is still very large.
  • the present invention achieves the object of designing a winding machine of the known type in such a way that it is suitable for winding several threads.
  • a plurality of threads starting from the same direction are to be wound up close together on a single winding spindle in a plurality of winding regions aligned with one another.
  • the wings preferably have on their side facing away from the pushing edge a leading edge - referred to in this application as a "brake flag" - which is shaped in such a way that its point of intersection with the guide ruler moves essentially at the traversing speed in the direction of the traversing stroke center. This prevents the thread from moving faster to the center of the traversing stroke than corresponds to the guide speed of the pushing edge of the wing traveling to the center of the traversing stroke.
  • all wings of all traversing devices according to the invention are distributed in only two planes of rotation ensures that the smallest possible distance exists between the wings.
  • the coaxial arrangement of all guide rollers ensures uniform thread running conditions from one traversing area to the other, so that bobbins with the same winding properties are wound up.
  • the coaxial arrangement of the guide rollers below and close to the lower plane of rotation of the wings enables one to be free with regard to the storage and arrangement of the bobbins, provided that only the surface line of the bobbin on which the thread runs, parallel to the guide roller and at a close distance is at the guide roller or in circumferential contact with the guide roller. Under these conditions, it is possible to wind up cylindrical or conical bobbins or wind up bobbins with different start or duration or end of the winding time.
  • the guideline be on the side of the thread running plane on which the gear and the drive of the blades or rotors are located; it is also proposed that the guide rule can be moved away from the rotor axes until the driver arms no longer cover the guide rule.
  • this embodiment offers the advantageous possibility of providing the guide ruler with a thread catching and thread guide notch outside of its traversing stroke.
  • the thread slides into this thread guide notch.
  • the thread guide notch is advantageously arranged on both sides of the traversing stroke.
  • the ruler can serve as a thread guide in this version, z. B. to guide the running thread in a catch zone and / or a thread reserve zone of the bobbin.
  • the guide ruler can also be movable parallel to its position and / or orthogonally to the rotor axes.
  • the shape of the guideline also offers the advantageous possibility of realizing certain movement laws for the thread, in particular also the possibility of reducing the traversing speed of the thread in the central region of the traversing stroke, so that there is an accumulation of Thread material results which is approx. 2% higher than the thread deposit in the end areas.
  • the arrangement of the guideline on the side of the thread run, on which the gears of the rotors also lie, also gives the possibility of protecting the wings on the thread run and operating side by a protective strip, which extends in the thread running direction over the rotary planes of the wings extends beyond.
  • This protective strip is cantilevered at one end of the lifting area and extends parallel to the traversing plane of the threads over the length of a traversing stroke. At the other end of this stroke range, the protective strip forms a threading slot directed into the thread running plane.
  • This design ensures that injuries from the rotating wing are avoided on the one hand, but on the other hand the wing is not in the handling of the thread, for. B. damaged by the thread guide suction gun when threading.
  • the threading slot opens into a winding area provided for a thread reserve, where the thread is found and guided over a few turns into the area of the traversing stroke and released there so that it can be found by the wings.
  • the guide rule be designed as a positive guidance at least in some areas.
  • the guide ruler has a front and a rear guide rail. This makes it possible to prevent the thread from lifting off the guide rail. This is particularly advantageous at the traversing stroke ends if the thread is to be laid there with increased accelerations and / or decelerations in accordance with a laying law.
  • the traversing device is preferably inclined in such a way that the planes of rotation of the wings do not penetrate the running plane of the thread at right angles, but instead enclose a smallest angle with the running plane of the threads in the region of the thread approaching the planes of rotation, which is between 45 and 70.
  • the drag length between the planes of rotation of the wings and the point at which the thread hits the guide roller can be made even less than the radius of the guide roller.
  • the guide roller From the guide roller, the thread is guided to the bobbin essentially free of drag lengths.
  • the guide roller can rest on the circumference of the spool.
  • the guide roller serves at the same time to increase the distance between the winding spindle axis and traversing with increasing winding diameter.
  • the guide roller is resiliently suspended so that it can avoid the roundness of the coil.
  • this resilient suspension of the guide rollers enables the simultaneous use of drive rollers.
  • the resilient suspension of the guide rollers prevents either the drive roller or the guide roller from lifting off the circumference of the spool in the course of the winding travel as the spool diameter increases.
  • the drive roller and guide roller and traversing mechanism are mounted together on a slide, the guide roller being resiliently movable relative to this slide.
  • the drive device of the carriage can be controlled as a function of a resilient deflection of the drive roller.
  • the traversing device is maintenance-friendly, especially when removing winders, that the gear and also the drive of the rotors are located on the side of the rotating planes facing the winding spindle - that is, in the thread running direction - behind the rotating planes of the wings. This avoids the need to dismantle the gearbox of the rotors if winders have formed on the rotors.
  • one of the rotors has a hollow shaft which is rotatably mounted.
  • a shaft on which the other rotor is seated is eccentrically mounted in this hollow shaft.
  • the hollow shaft and the shaft can be separated from each other, e.g. B. driven by belts or gears.
  • a preferred embodiment provides that the hollow shaft and the shaft are connected to one another by gearing, in particular by means of a countershaft which is mounted within the hollow shaft and which the hollow shaft and the shaft geared together in such a way that both rotate at the same speed, but opposite direction of rotation and an exact phase position.
  • the phase position of the wings is otherwise to be adjusted so that collision and damage to the wings is avoided.
  • the phase shift of the blades is also a function of the center distance of the axes of rotation of the blades in their planes of rotation.
  • a mutual phase shift of two adjacent vanes of essentially 90 is preferably selected and has proven itself for a plurality of traversing areas lying close together.
  • This described design configuration offers the advantageous possibility of providing a housing as a structural unit for each stroke range, in which the two rotors of this stroke range are mounted.
  • This housing can be installed and removed independently of the other lifting ranges for maintenance and repair.
  • the exact phase relationship of the rotors to each other can be set in the manufacturer's factory during final assembly.
  • only one of the shafts is driven from the outside, preferably the hollow shaft.
  • a belt drive, gear drive, worm gear drive or the like can again be used for the drive.
  • An advantageous gear connection of the rotors has a common worm shaft for the rotors each assigned to a rotary plane.
  • the rotors of a rotating plane are each driven by a tangential belt.
  • the rotors of a rotary plane can be driven by bevel gears from a drive shaft common to them, which extends over all traversing stroke ranges.
  • the rotors of the other rotary plane are each also driven by one of these drive options or from the first rotor via intermediate gears in such a way that the speed for the rotors assigned to a traversing stroke is the same, but the direction of rotation is opposite and the required phase position for exact Thread transfer is guaranteed at the stroke ends.
  • the gear of the rotors, the blades of which are located in the upper rotary plane, as viewed in the direction of the thread, is above these blades and the gear of the rotors, the blades of which rotate in the lower rotary plane, is below this rotary plane.
  • the housing is preferably divided so that the upper housing part can be removed from the lower housing part, e.g. B. can swing away. This is also advantageous for removing the winder and other maintenance.
  • the structure of the winding machines is shown schematically from the cross sections according to FIGS. 2 and 3.
  • Several winding tubes 15 are placed axially one behind the other on the winding spindle 14.
  • the winding spindle 14 is driven in rotation with the direction of rotation 31.
  • a plurality of threads 4 are thereby wound into a corresponding number of bobbins 13.
  • Each thread previously runs through a traversing device 1 or 2 or 3, by means of which the thread is periodically moved back and forth over the length of its bobbin and transversely to its running direction.
  • the design of the traversing device which differs to a certain extent from the exemplary embodiment according to FIG. 3 in the exemplary embodiment according to FIG. 2, will be discussed later.

  • the wings in the rotary plane I are designated 5 and the wings in the rotary plane II with 6.
  • the wings 5 of the traversing devices 1, 2 and 3, which are arranged in the rotary plane I accordingly have the designation 5.1, 5.2, 5.3 and also the wings in the rotary plane II are provided with the corresponding index of their traversing device 1 or 2 or 3. It follows that the wings of all traversing areas are arranged in only two planes of rotation I and II.
  • the center distance A is selected so that it is smaller than the diameter of the wing, but larger than V2 x wing radius. This ensures that the distance B between the winding areas H1, H2, H3 is very small. This makes it possible to produce a plurality of coils 13 by means of an aligned row of traversing devices 1, 2, 3, which are preferably - as shown in the exemplary embodiments - clamped and driven on a single winding spindle 14.
  • FIG. 2 shows that the guide ruler 9 can lie on the same side as the traverse with respect to the thread path, specifically in a plane 111. It is shown in broken lines that the guide ruler can also lie on the other side. However, a combination is also possible such that a guide rail 29, 30 is located in front of and behind the thread 4.
  • the guide ruler 9 represents a positive guidance of the thread. This positive guidance can extend over the entire stroke range, but it can also - as shown in FIG. 4 - be restricted to partial areas.
  • the guide ruler 9 is on the same side as the traverse with respect to the thread path.
  • the guide ruler can be moved essentially orthogonally to the axes 10, 11 of the wings 5, 6 (arrow 32).

  • the gear mechanism for the shafts 10 and 11 of the wings 5 and 6 is arranged below the lower plane of rotation II in the thread running direction, that is to say between the oscillation 1 or 2 or 3 and the coil 13 in the housing 33.
  • the transmission consists - as indicated schematically - on the one hand of a hollow shaft 11 on which the vanes 6 of the lower rotary plane II are attached, and on the other hand from the shaft 10 which is mounted in the hollow shaft 11 and on which the vanes 5 of the upper rotary plane I are attached.
  • the two shafts are driven by worm wheels 16 and 17 and worms 18 and 19.
  • the worm shafts extend in the longitudinal direction of the winding spindle 14 over all traverses 1, 2, 3. Their drive motor is not shown.
  • the gear for the wing 5 of the upper rotary plane I above this rotary plane and the gear for the wing 6 of the lower rotary plane II is attached below this rotary plane.
  • the gears are located in an upper housing part 23 and a lower housing part 24. Both gears are synchronized with one another by belt drive 20. Dental rhymes are therefore preferably used.

  • the thread guide ruler 9 has the thread catching notches 28 at its two ends outside the stroke range.
  • the guide ruler also consists of an outer guide rail 29 and an inner guide rail 30.
  • the guide rail 29 extends only over a partial area of the stroke. The thread is forced in this area. This is particularly advantageous to the thread special laws of motion, for. B. impose larger accelerations or decelerations.
  • the guide rail 9 can be moved in the direction of the arrow 32 such that the inner guide rail 30 comes out of the turning circle of the wings 5 and 6, respectively.
  • this position shown in dashed lines
  • the thread 4 no longer has a guide, so that it slips into one of the thread catching notches 28 located to the side of the lifting area. In this position, the thread can either be caught and vacuumed.
  • This backward movement of the guide ruler 9 then starts the oscillation again, since the thread catch notches 28 lie within the turning circle of the wings 5 and 6, respectively.
  • the guide carriage 42 is on the guide rod 41 movable relative to the coils 13.
  • the traversing devices according to the invention are mounted on the guide carriage 42.

If the guide roller is to serve as a control roller, its speed is measured continuously and the measured value is given to an axle drive motor for the winding device in such a way that the peripheral speed of the bobbin remains constant as the bobbin diameter increases.
  • FIG. 6 shows a detail of the traversing housing according to FIG. 5. It is shown in FIGS. 5 and 6 that each traversing stroke area is covered by a protective strip 75 on the front of the machine.
  • This protective strip 75 in particular also covers the rotary planes I and 11 in the direction of the thread. On the one hand, this means that you cannot reach into the rotating wings. On the other hand, it is also prevented that one gets into the turning area of the wing when threading with the thread suction gun, thereby damaging the wing and changing its phase position.
  • the protective strip 75 forms a thread guide slot 76 with respect to the guide ruler 9 (not shown in FIG. 6).
  • Each protective strip 75 is cantilevered at one end, while at the other end it forms a threading opening 77 which opens into the guide groove 79 of a thread reserve device 78.

  • the gear rim 72 is driven by drive belts 73, for which purpose the housing pot 65 has a corresponding recess.
  • the rotary movement of the hollow shaft 11 with the gear rim 68 is transmitted via gear 69, the countershaft 66, which is also rotatably mounted in the housing pot 65, and the gear wheels 70 and 71 to the shaft 10 in such a way that the shaft 10 rotates in the opposite direction of rotation, but at the same speed .
  • this unit can be preassembled in such a way that the phase position of the wings 5 and 6 is already set so that an exact thread transfer is guaranteed at the reversal points.
