Description

  The present invention relates to a yarn guide device disposed between a drafting device outlet for a ring spinning machine and a ring spindle, wherein the yarn guide device is disposed at a distance above the upper end of the ring spindle. The present invention relates to a yarn guide device having parts, wherein the twisted parts are connected to a ring spindle by a magnetic field and are rotated at the same speed as the ring spindle.

  It is known that the yarn of a ring spinning machine is mainly cut between a yarn guide device and a drafting device in a so-called spinning section. In this region, the roving yarn discharged from the drafting device does not yet have enough stability to resist the abnormal tension on the yarn. Moreover, conventional yarn guide devices, so-called yarn guide eyelets, can partially impede additional rotation in the spinning section.

  In order to solve this problem, technical experts have studied over the past several decades and various proposals have been made. For example, in order to improve the strength of the roving yarn discharged from the drafting device, in order to make the twisting movement towards the spinning triangle caused by the traveler rotating around the ring more effective, so-called crown It was proposed to place the on a ring spindle. In the case of such a spindle crown, the yarn is placed in the crown teeth and conveyed by the teeth, but the yarn at the crown must move in the same reverse direction as the traveler on the spinning ring, The movement is slower than the peripheral speed of the spindle depending on the winding and winding speed. This means that the thread jumps back from tooth to tooth as the traveler stays behind. The friction generated at this time leads to undesirable yarn damage and roughening. In addition, the traveler is shocked at every jump. These spindle crown caps consequently promote the wear and tear of the traveler.

  When using a so-called spinning finger as the crown on the ring spindle, there is no crown depression and the spinning finger is smooth, which reduces the roughening of the yarn. However, the spinning fingers effectively function like a crown with one indentation, around which the yarn travels. This means that the jump is increased by about one revolution. The traveler stops for a moment at the moment of jumping and then accelerates again. Therefore, the countermeasure with this spinning finger leads to a large yarn seam. In addition, the spinning fingers cannot be aligned, which requires a special spindle bearing that can withstand this non-aligned arrangement.

  In order to avoid these problems, it has been proposed to provide a rotary yarn guide device. This rotary yarn guide device is composed of twisted parts supported by ball bearings, and is made of ceramic for this purpose. The spindle is above the upper end of the ring spindle with respect to the device frame. Are arranged independently. The twisted part and the spindle are magnetically coupled via a permanent magnet incorporated in the spindle head and the twisted part, and these are interlocked with each other during rotation. The speed of the spindle is therefore transmitted synchronously to the twisted part via this magnetic connection. In this known device (Textilpraxis International 1982, pages 19-20), the yarn in the spinning section is given a reverse rotation because it contacts the top of the spindle as it passes through the twisted part. However, it is clear that the effect of this rotary yarn guide device is not satisfactory. This is because the yarn slips considerably upon contact, so that the reverse rotation is unstable and therefore not satisfactory. In addition to this, there are also intermittent effects. This is because the yarn is sufficiently in contact with the friction body described above to undergo rotation only for a short period of time that is part of the overall rotation of the balloon or traveler. In addition, the efficiency of the known devices described above is highly dependent on the yarn flow. No significant reduction in yarn tension and / or yarn breakage has been identified so far. Apart from the problem with threading, the problem of thread cutting in ring spinning machines is generally not solved by this rotary thread guide device. In addition, it has been found that there is a problem in the magnetic coupling between the spindle and the yarn guiding device that the controlled yarn guiding operation must be abandoned from the beginning.

  DE19629787A1 discloses a rotary yarn guide device arranged as a twisting device between a normal yarn guide part on a spindle and a ring traveler immediately above the ring spindle, in which the rotating body is magnetically connected to the spindle. Is disclosed. The sliver is fed to the center position and conveyed to the side of the rotating body, from which the sliver in the balloon is extended toward the ring traveler. Alternatively, the rotor can be provided with a helical channel, but the rotor must be operated slower or faster than the spindle independently of the spindle. This requires that the sliver be temporarily subjected to a slight reverse twist. This known apparatus has never been put into practical use. This is because the external drive device is too expensive and accurate rotation cannot be applied.

  The object of the present invention is to provide a device that avoids the above technical problems and can reliably maintain good and accurate propagation of rotation to the spinning triangle. Moreover, the device needs to be simple and easy to operate.

The above-described problem is a yarn guide device disposed between a drafting device outlet for a ring spinning machine and a ring spindle according to claim 1, wherein the yarn guide device is located above the upper end of the ring spindle. Having twisted parts arranged at a distance, the twisted parts being connected to the ring spindle by a magnetic field and rotating at the same speed as the ring spindle, the twisted parts (10, 11) being the carrier (12, 13), the carrier (12, 13) extends coaxially with the rotation axis, and the core (12 ', 13) around which the yarn passing through the yarn guide device can be wound. ′) And edges (14, 15, 15 ′) on the core (12 ′, 13 ′), the carrier is configured as a spiral structure (13), and the yarn guide device (1 100) from the working position This is achieved by a yarn guiding device characterized in that it can be turned to the operating position (1 ') .
Further, the above-mentioned problem is a yarn guide device arranged between the drafting device outlet for the ring spinning machine and the ring spindle according to claim 2, wherein the yarn guide device is located above the upper end of the ring spindle. The twisted parts are arranged at a distance from each other, the twisted parts are connected to the ring spindle by a magnetic field, and are rotated at the same speed as the ring spindle, and the twisted parts (10, 11) A carrier (12) having a core (12 ') extending coaxially with the axis of rotation and around which a thread passing through a thread guiding device can be wound; As a transverse member extending in the transverse direction with respect to the core (12 ′) extending in the direction of the core (12 ′), it is configured as a cross-shaped carrier composed of an edge portion (14) fixed to the core (12 ′), and the yarn guiding device (1 , 100) It is accomplished by the yarn guide device, characterized in that is so pivotable from work position to the operating position (1 ').
Further, the above-mentioned problem is a yarn guide device arranged between the drafting device outlet for the ring spinning machine and the ring spindle according to claim 3, wherein the yarn guide device is located above the upper end of the ring spindle. The twisted parts are arranged at a distance from each other, the twisted parts are connected to the ring spindle by a magnetic field, and are rotated at the same speed as the ring spindle, and the twisted parts (10, 11) has a carrier (12), said carrier (12) includes a core (12 ') that can take the yarn passing through the yarn guide device in which and around extends coaxially with the rotary axis is wound, machine direction As a transverse member extending in the transverse direction with respect to the core (12 ′) extending in the direction of the core (12 ′), it is configured as a T-shaped carrier composed of an edge portion (14) fixed to the end of the core (12 ′). Guide device (1, 1 0) is achieved by the yarn guide device, characterized in that is adapted to be pivoted to the operating position from the working position (1 ').

  According to the configuration of the yarn guide device according to the first aspect, the yarn is accurately conveyed by the twisted parts, and the yarn is accurately rotated in an important region between the yarn guide device and the drafting device. During this time, the winding of the yarn is carried out continuously and without receiving an impact. Through forced transfer of the yarn, the effects of slippage and involuntary properties as in the case of friction transfer, and thus also the angle of introduction into the yarn guide device are eliminated. The winding of the twisted part around the core acts as a brake, thus reducing the sharp peaks of tension coming from the traveler and balloon and affecting the sensitive area between the yarn guide and drafting device. Can no longer affect. A balloon restricting ring is not required because tangles are reduced. Due to the winding of the yarn around the core in the direction opposite to the direction of rotation of the spindle, the rotation imparted from the spindle acts strongly between the yarn guiding device and the outlet of the drafting device. The rotation is propagated until just before the drafting device exit, and a rapid strengthening of the discharged roving is achieved.

  Preferably, the carrier is configured as a helical structure. This is because the spiral structure causes the yarn to be wound accurately. Therefore, an operation error is avoided. Depending on the magnitude of the winding angle at which the yarn wraps around the core of the carrier, the braking effect can be reduced or increased. In order to achieve an optimum braking effect, the winding angle α of the helical structure is in the range of about 360-720 °, preferably about 540 °. Further, the winding of the yarn described above can affect the region between the yarn guiding device and the drafting device outlet. In order to convey the yarn satisfactorily without roughening, the upper and lower ends of the spiral structure are configured as edges, and these edges are arranged in a plane perpendicular to the rotation axis of the spiral structure. It is preferably configured as a rounded edge.

  The housing of the twisted part protects not only the twisted part but also the running of the thread, and avoids tangling or knotting of the thread when the thread breaks. In addition, the case enables automatic threading by suction air, and thus shortens the operation time for recovery from thread cutting. In order to avoid lump clumps or to remove frictional heat, vents can preferably be provided in the housing of the twisted parts.

  Surprisingly, when the yarn introduction port is arranged at an eccentric position, a balloon is not formed between the yarn guide device and the drafting device. The eccentricity is adjusted to be approximately equal to the radius of the carrier core. When the yarn discharge port is arranged at the center position, twisting is performed without vibration. In order to avoid an increase in yarn tension, it is appropriate to arrange the yarn guide device at a center position above the upper end of the ring spindle and at a predetermined distance from the upper end of the sleeve placed on the ring spindle. I understood it. A gap of at least 25 mm has been found suitable for this purpose. In general, it has been found that a length difference corresponding to the radius of the spinning ring is appropriate.

  If the yarn guide device can be rotated from the operating position to the operation position, it not only enables smooth manual or automatic pulling of the wound body, but also helps to maintain and clean the yarn guide device. Preferably, the yarn guide device can be coupled in the operating position to a suction device that can be operated simultaneously through movement of the yarn guide device to the operating position. In this way, the yarn guiding device is prevented from soiling the fiber scraps, and the yarn can be passed through the yarn guiding device by the suction device in order to start spinning again. When the support body of the yarn guide device is bent, it is easy to use the balloon limiting ring fixed on the ring base.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a cross-sectional view of the configuration of a rotary yarn guide device. This device includes a casing 2 having a yarn introduction port 21 arranged at an eccentric position, and a twisted part 11 having a yarn discharge port 22 arranged so as to be rotatable in the ball bearing 16 and arranged at a central position. It is configured. A carrier 13 is provided in the twisted part 11 and is fixed to the twisted part. The carrier 13 rotates together with the twisted part 11. The carrier 13 has a core 13 ′ extending coaxially with the rotating shaft, and a thread F extending from the drafting device outlet to the spindle 3 can be wound around the core 13 ′. On the core 13 ', one upper edge 15 and one lower edge 15' are provided. The yarn traveling through the yarn guide device 1 is located on this edge and is conveyed as the twisted part 11 rotates.

  The twisted part 11 provided with the carrier 13 is appropriately surrounded by the housing 2 in order to protect the yarn passing through the twisted part 11 and to avoid entanglement or knotting of the yarn when the yarn breaks. The housing 2 is placed on a bearing ring 17 that serves to accommodate the ball bearing 16. The bearing ring 17 is accommodated in a holder 18, and the holder 18 can turn around a hinge 19. By this turning, the yarn guiding means 1 can turn to the high operating position 1 ′ indicated by the dotted line, so that the head of the spindle 3 is freed and the sleeve 4 is put on to remove the wound body. Therefore, the spindle can be easily accessed.

  In the ring spinning machine, another suction device 5 in the form of a pipe is arranged in parallel with a normal roving suction device arranged below the roller of the drafting device. For each spinning position, the pipe 5 is provided with a suction port 51, the yarn introduction port 21 of the yarn guide device 1 at the operation position 1 ′ is located at the position of the suction port 51, and the suction device The suction air is sucked through the yarn guide device 1 by 5. On the other hand, the ventilation by this suction serves to prevent the yarn guiding device 1 from being soiled by fiber scraps and other coarse deposits. On the other hand, since the yarn F conveyed by the spindle 3 can be disposed in front of the yarn discharge port 22 at the center position, the yarn can be sucked into the yarn guide device 1 and threaded. For repeated spinning, the yarn guide device 1 is moved from its operating position 1 'to the operating position indicated by the solid line. By a known method, the yarn F extending from the yarn introduction port 21 into the suction port 51 is taken out for the start of the spinning process and placed on the drafting device.

  Preferably, the suction port 51 can be opened and closed via movement of the yarn guide device in order to prevent unnecessary air consumption in the operating position. For this opening and closing, a cam that acts to push the lock of the suction device 5 or to operate the suction device in another state is arranged at the position of the yarn introduction port 21 of the yarn guide device 1. If the suction device 5 is placed on the suction port 51, the suction device 5 is operated, and when the yarn guide device 1 turns and returns to the operation position, the suction port 51 is closed again. can do.

  The part of the twisted part 11 facing the spindle 3 is configured as a magnet and forms a magnetic connection with the head 31 of the spindle 3 similarly provided with a permanent magnet so that the twisted part 11 rotates at the same speed as the spindle 3. It has become. As is well known, the distance from the twisted part 11 to the spindle head 31 is determined by a magnetic field necessary for reliably carrying the twisted part 11 by the spindle 3. Generally, this spacing is about 5-10 mm.

In the simplest configuration, as shown in FIG. 5, the carrier 12 is configured in a cross shape or a T shape, and the carrier 12 includes a core 12 ′ and an edge portion 14. A thread passing through the thread guiding device 100 is wound around the core 12 ', and the edge portion 14 is fixed to the core 12' as a transverse beam (transverse member) . The edge portion 14 captures the yarn F introduced from the yarn introduction port 24 and applies a rotation similar to the speed of the spindle to the yarn F. The yarn exits the yarn guide device 100 through the yarn discharge port 23 in the twisted component 10. As in the configuration of FIG. 1, the twisted part 10 is provided in a ball bearing 16 on a holder 18 so that it can rotate in a bearing ring 17. Interlocking between the spindle head 31 and the twisted part 10 is performed through the above-described magnetic connection.

  The yarn F is wound around the core 12 ′ of the carrier 12 in order to prevent the entire balloon tension from being transmitted to the twisted yarn section between the yarn guide device 100 and the drafting device outlet. Depending on the coefficient of friction of the surface of the core 12 'of the carrier 12, the yarn around the core is wound once or twice in order to maintain the desired braking action. In the simple configuration shown in FIG. 5, more time is required for manual threading by the operator because of such winding of the yarn. The housing 20 needs to be removable for this purpose. In addition, winding of the yarn only for one or half turn is also conceivable. For example, more detailed calibration is possible if another cross cam is provided as a lower edge of the carrier with a 90 ° offset relative to the edge 14.

Therefore, in the configuration shown in FIG. 1, as shown in detail in FIG. 2, the carrier 13 is configured as a spiral structure. The spiral structure 13 includes an edge 15 at its upper end and an edge 15 ′ at its lower end. The yarn F runs on these edges and enters the spiral structure 13 and exits from the spiral structure. Both edges 15 and 15 ′ accurately determine the winding angle α of the spiral structure 13 and thus automatically determine the winding of the thread around the core 13 ′. As described above, the yarn is sucked and automatically positioned in the path of the spiral structure 13, and the desired yarn winding is achieved. To ensure smooth running and easy threading of the yarn in operation, the edges 15 and 15 'are preferably configured rounded as a band Vita portion.

  Due to the large load caused by the running of the yarn, this helical structure 13 is preferably made of ceramic or metal with a wear-resistant sintered coating. In order to adjust the desired braking action, in addition to the winding of the yarn, a special friction coefficient μ can be given to the surface by the surface of the ceramic part or by a sintered coating. As a result of the examination so far, it has been found that sufficient braking action can be obtained when the winding angle is at least 360 °. It has been found that the winding of the yarn with a winding angle α of about 540 ° (about 3/2 rotations) is the optimum value.

  The braking action works as follows. Through the friction of the yarn caused by the winding of the yarn on the carrier 12 or 13, a stronger attractive force is applied to the yarn balloon, which results in a smaller balloon. This eliminates the need for a balloon limiting ring and its actuation control. However, these parts are still necessary for winding the lower end of the wound body. On the other hand, the tension in the spinning section between the yarn guiding device and the drafting device is considerably reduced because the tension is retained via friction on the carrier 12 or 13. In particular, the sharp peaks of tension caused by the traveler and balloon that frequently caused the yarn to break are removed from this spinning section.

  While applying rotation by the carrier 12 or 13, the winding of the yarn on the carrier has an inhibitory effect on the propagation of the rotation towards the balloon / spin ring of the yarn. Accumulation of rotation occurs in part of the yarn F ′ (FIG. 6), so that the yarn discharged from the drafting device undergoes rotation and is immediately strengthened. The propagation of rotation towards the drafting device outlet obviously depends on which direction the winding of the yarn around the core 12 'or 13' of the carrier 12 or 13 is taking place. Winding in the direction opposite to the direction of rotation of the spindle 3 has the effect of promoting the propagation of rotation in the direction of the exit of the drafting device. Therefore, the operator must check not only whether the rotation is occurring at the desired winding angle but also whether it is in the correct direction.

  When the carrier 13 shown in FIG. 2 is arranged, not only the desired winding angle α but also the correct direction is automatically realized during threading due to its helical structure. Therefore, an operation error is avoided.

  The function of the yarn guide device is as follows. The yarn F ′ discharged from the drafting device travels through the yarn introduction port 21 or 24 of the housing 2 of the yarn guide device 1 or the housing 20 of the yarn guide device 100, and the yarn discharge of these yarn guide devices. Exit the yarn guide through exit 22 or 23. A carrier 12 with edges 15 and 15 'or edges 14 rotating with the carrier 13 catches the yarn F extending through the housing 2 or 20, and the spindle 3 twists via a magnetic connection. Since the component 10 or 11 is being driven, the yarn is imparted with a rotation suitable for the speed of the spindle through its conveyance. The yarn F that has left the twisted part 10 or 11 travels under a traveler 63 that normally rotates around the spinning ring 62 via a yarn balloon and travels to the winding portion of the wound body on the sleeve 4. To do. Since the traveler 63 is delayed from the angular velocity of the spindle 3 due to the winding of the yarn, the true rotation received by the yarn F ′ in the spinning section is reduced by this amount. However, in order to strengthen the roving yarn discharged from the drafting device, the advantage is obtained that a greater rotation is provided in the spinning section that can be braked accurately by the carrier 12 or 13. This rotation propagates to the spinning triangle. This gives the sliver an accurate rotation immediately after it is ejected from the drafting device. Jumps on conventional crown indentations and the like are eliminated, and the twistlessness caused by friction is avoided.

  According to the yarn guide device of the present invention, in an important region between the draft device outlet and the yarn guide device, the yarn F ′ before the spinning triangle has a rotation of 109% of the target rotation at a winding angle of 360 °. The measurement results showed that at the 720 ° winding angle, a rotation of 115% of the target rotation was achieved in the final yarn. On the other hand, according to the conventional yarn guide device having a balloon restricting ring, only 84% of the target rotation was achieved before the spinning triangle. This means that the spinning triangles shrink and the discharged sliver is strengthened in the critical areas just described. Therefore, thread cutting hardly occurs in this region. From these measurement results, it can be seen that the magnitude of the winding angle α is more important, but this value usually has an upper limit. This is because, when the winding angle α is too large, the tensile strength required on the yarn balloon side becomes too large, and the yarn is cut in the traveler region. This knowledge can be used to perform spinning with little yarn breakage through adjustment of the winding angle α and the dimensions of the carrier 12 or 13. According to actual tests, it has been found that it is particularly preferable that the winding angle α is 540 °, the radius of the core 13 ′ is 1.5 mm, and the height of the helical structure is 15 mm.

  The correction of the difference between the angular velocity of the spindle 3 and the traveler 63 takes place after the yarn F leaves the twisted part 11 or 10 towards the traveler / spinning ring. The yarn F is free to move in the gap between the spindle head 31 and the twisted part 10 or 11, so that this correction is performed continuously, unlike the measures against rotational propagation known in the prior art. It is desirable that the yarn be able to move as freely as possible in this gap, but although it may contact the spindle head 31, it should not be so close that the torque affects the yarn, in particular the twist. Touching in the direction that can be solved should be avoided. Therefore, a sufficiently large balloon exists in the interval h between the upper end of the sleeve 4 and the yarn guide device 1 or 100 even when the ring base 6 is at the upper limit position, and therefore, the spindle head 31 is not touched as much as possible. It is necessary to maintain an interval so as not to contact at all. On the other hand, in order to guarantee the transport of the twisted part 10 or 11, the magnetic connection between the spindle head 31 and the yarn guiding device 1 or 100 is realized with a smaller gap of about 5 to 10 mm. Therefore, it is necessary to extend the spindle beyond the upper end of the sleeve 4 by at least about 25 mm, for example. Depending on the diameter of the spinning ring and the balloon of the yarn depending on it, it has been found that it is preferred to stretch it at least by a length corresponding to the radius of the spinning ring.

  In the configuration shown in FIG. 5, the yarn introduction port 24 arranged at the center position is shown. In the configuration shown in FIG. 1, the yarn introduction port 21 is provided eccentrically. Surprisingly, it can be seen that the formation of a balloon between the yarn guide device 1 or 100 and the outlet of the drafting device is avoided, so that the eccentric thread introduction port 21 is better than the central yarn introduction port 24. ing. The eccentricity e of the yarn introduction port 21 with respect to the rotation axis of the carrier 13 is preferably equal to the radius of the core 13 ′ of the spiral structure 13 (FIG. 4). In the configuration shown in FIG. 5 as well, in order to avoid the formation of a balloon, the yarn introduction port 24 should be arranged eccentric to the rotation axis of the carrier 12 by the radius of the core 12 ′. On the contrary, since the guide at the center position of the thread avoids the vibration of the thread balloon and hence the sharp peak of tension due to the vibration, the thread discharge port at the center position as shown in FIG. It is more preferable than the arrangement of the yarn discharge port at the eccentric position as shown. In order to promote the discharge of the yarn at the central position, the yarn F wound around the core 13 ′ is guided from the lower edge 15 ′ of the spiral structure 13 to the space 25 below the carrier 13 in the twisted part 11. Thus, the yarn F reaches the yarn discharge port 22 at the center position.

  FIG. 6 schematically shows the entire spinning station including the spindle 3 with the shock absorber 32, the ring table 6 and the spinning ring 62. In this configuration, the balloon limiting ring 61 is fixed to the ring base 6. In the yarn guide device of the present invention, since the balloon restricting ring 61 is necessary while winding the lower end portion of the wound body, separate operation control can be avoided. However, since the movement of the balloon restricting ring 61 can be hindered by the support of the yarn guide device 1 or 100 while winding the upper end of the wound yarn body, the bent support 181 for the yarn guide device 1 or 100 is used. This bent support 181 passes through the balloon restricting ring 61, thus ensuring a gap for the magnetic coupling of the twisted parts 10 or 11. In the drawing, a balloon restriction ring 61 having a ring base 6 when an upper position necessary for winding the wound body is assumed is indicated by a dotted line.

  FIG. 7 shows another configuration of the housing 200 in the yarn guide device 1 or 100. Ventilation holes 26 are provided to avoid the accumulation of fiber waste in the housing 200 and to remove the heat generated by the friction of the yarn or due to the ball bearing 16.

  As mentioned above, although the thread | yarn guide apparatus of this invention was demonstrated based on two structure forms, this invention is not limited to the form of the above-mentioned carrier 12 or 13, for example. Other forms of carriers, such as small holes, for example, can also utilize the idea of the present invention and perform the intended function in a similar manner. The present invention is also not limited to the above-mentioned application in conventional ring spinning, but the present invention is very effective in that two draft rovings discharged from a drafting device called “SIRO spinning” are double-yarned. It can be applied to the method of spinning to the form. In this case, for example, by using the above-described invention, the triangle between both rovings traveling simultaneously can be reduced in half at the drafting device outlet.
