Description

  The present invention relates to a spinning winder that winds a plurality of yarns sent from a spinning unit around a plurality of bobbins.

  In the winding machine (spinning winder) described in Patent Document 1, distribution rollers (guide rollers) are respectively disposed almost directly above a plurality of bobbins mounted in a row. The plurality of yarns fed from the spinning unit and wound around the goded roller are distributed to a plurality of bobbins by a plurality of distribution rollers, and then traversed by a traverse guide disposed between each bobbin and the distribution rollers. While being wound, it is wound around a plurality of bobbins. Also, an air bearing device is provided on the roller shaft that supports the guide roller, and the guide roller is supported so as to be freely rotatable by supplying compressed air between the guide roller and the roller shaft by the air bearing device. Has been. As a result, friction is unlikely to occur between the traveling yarn and the guide roller.

Special table 2008-531438 gazette

  However, in the winder described in Patent Document 1, it is necessary to form a slight gap between the guide roller and the roller shaft so that the guide roller is supported so as to freely rotate. High accuracy is required for the guide roller and the roller shaft. In addition, if foreign matter such as dust enters the gap, this foreign matter becomes resistance and the rotational resistance of the guide roller increases, so frequent maintenance is required to prevent foreign matter from accumulating in the gap. .

  Here, in order to support the guide roller so as to be freely rotatable, a ball bearing may be interposed between the distribution roller and the roller shaft instead of providing the air bearing device as described above. However, in this case, when the distribution roller rotates at a high speed in accordance with the traveling of the yarn, the ball bearing also rotates at a high speed at substantially the same rotational speed as the distribution roller, and the life of the ball bearing is shortened.

  Further, in order to make the distribution roller freely rotatable so that friction is less likely to occur between the traveling yarn and the ball bearing, the ball bearing has a very small rotational resistance, that is, a small size, and It is necessary to reduce the amount of lubricating oil that causes viscous resistance. However, since such a ball bearing has low durability, the life of the bearing is further shortened.

  In addition, if the rotational resistance of the ball bearing increases even slightly, the distribution roller becomes difficult to rotate, and friction is generated between the yarn and the distribution roller. Therefore, the ball bearing is kept in a low rotational resistance state. Therefore, frequent maintenance is required.

  An object of the present invention is to provide a spinning winder that has little friction between the traveling yarn and the distribution roller, has a long life, and does not require frequent maintenance.

  A spinning winder according to a first aspect of the present invention is a spinning winder that winds a plurality of yarns sent from a spinning section onto a plurality of bobbins mounted in series along a winding shaft of a yarn winding device. A plurality of yarns sent from the spinning section are arranged along the winding shaft of the yarn winding device, and a goded roller on which the plurality of yarns are wound side by side along the axis thereof. A plurality of distribution rollers for distributing the plurality of yarns sent to the goded roller to the plurality of mounted bobbins, respectively, wherein the plurality of distribution rollers are drive rollers.

  According to the present invention, since the distribution roller is a drive roller, the rotation of the distribution roller in accordance with the speed of the traveling yarn makes it difficult for friction to occur between the traveling yarn and the distribution roller.

  When the distribution roller is a drive roller, it is necessary to provide a bearing between the rotation shaft of the distribution roller and a support member for supporting the rotation shaft. The rotating shaft of the distribution roller that rotates by receiving force is only required to be rotatable with respect to the support member, and has a high rotational resistance, that is, a large size and a large amount of lubricating oil. can do. Therefore, the bearing has high durability, and even when it rotates at high speed, its life can be extended.

  In addition, a bearing that can rotate the rotating shaft of a distribution roller that receives a driving force from a driving motor with respect to a support member is not a problem even if the rotational resistance fluctuates and becomes larger. There is no need to do so often.

  A spinning winder according to a second invention is characterized in that, in the spinning winder according to the first invention, a drive motor is individually provided for the plurality of distribution rollers.

  According to the present invention, since the drive motors are individually provided for the plurality of distribution rollers, each distribution roller can be accurately rotated in accordance with the traveling speed of the yarn.

  A spinning winder according to a third aspect of the invention is the spinning winder according to the first aspect of the invention, wherein the plurality of distribution rollers include a drive motor provided in common to the plurality of distribution rollers, and the plurality of distribution rollers. It is driven by a rotating shaft of the distributing roller and a driving belt wound around the rotating shaft of the driving motor.

  According to the present invention, since the plurality of distribution rollers can be rotated by using a common drive motor for the plurality of distribution rollers, the configuration of the apparatus is simplified.

  A spinning winder according to a fourth invention is the spinning winder according to any one of the first to third inventions, wherein a bearing is interposed between the distribution roller and the rotation shaft of the distribution roller. It is characterized by being.

  For example, when driving a plurality of distribution rollers by a drive motor provided in common to the plurality of distribution rollers, a rotation shaft of the plurality of distribution rollers and a drive belt wound around the rotation shaft of the drive motor The rotational speed of the rotating shaft of the distributing roller and the rotational shaft of the motor and the driving belt vary due to friction between the rotating shaft of the distributing roller and the rotational speed of the rotating shaft deviates from the rotational speed corresponding to the traveling speed of the yarn. There is a risk of it.

  However, according to the present invention, since the bearing is interposed between the distribution roller and its rotation shaft, even if the rotation speed of the rotation shaft of the distribution roller varies even when the yarn is hung on the distribution roller. Since the distribution roller rotates relative to the rotation shaft, the distribution roller continues to rotate at a rotation speed corresponding to the traveling speed of the yarn, and friction is hardly generated between the yarn and the distribution roller.

  In addition, there is no difference in rotational speed between the distribution roller and its rotating shaft, and when these are rotating integrally, the bearing hardly rotates, and there is a difference in rotational speed between the distribution roller and its rotating shaft. Is rotating relatively, but the rotation speed is smaller than the rotation speed of the rotation shaft, which corresponds to the difference in rotation speed between the distribution roller and the rotation shaft. The life of the bearing can be extended.

  Further, since this bearing is rotated by receiving the driving force transmitted from the rotating shaft of the distribution roller, the distribution roller does not become difficult to rotate even if the rotational resistance is increased somewhat. Friction does not easily occur between the distribution roller and the distribution roller. Therefore, it is not necessary to perform bearing maintenance so frequently.

  According to the present invention, since the distribution roller is a driving roller, the rotation of the distribution roller in accordance with the speed of the traveling yarn makes it difficult for friction to occur between the traveling yarn and the distribution roller.

  Further, the bearing provided between the rotation shaft of the distribution roller and the support member for supporting the rotation shaft has a rotation shaft of the distribution roller that rotates by receiving a certain amount of driving force from the drive motor with respect to the support member. And can be rotated, and can have a large rotational resistance, that is, a large size and a large amount of lubricating oil. Therefore, the bearing has high durability, and even when it rotates at high speed, its life can be extended.

  In addition, a bearing that allows the rotating shaft of the distribution roller that rotates by receiving a driving force from the drive motor to rotate relative to the support member does not pose a problem even if the rotational resistance fluctuates slightly, so that maintenance is also frequent. There is no need to do it.

[First Embodiment]
Hereinafter, a preferred first embodiment of the present invention will be described.

  FIG. 1 is a front view of the take-up winder according to the first embodiment. FIG. 2 is a side view of the spinning winder according to the first embodiment. In the following description, as shown in FIG. 1 and FIG.

  As shown in FIGS. 1 and 2, the spinning winder 1 sends a plurality of yarns Y continuously supplied from the upper spinning machine 2 to the lower winding unit 3 via the transport unit 4. Winding is performed by the winding unit 3.

  The spinning machine 2 spins a plurality of yarns Y, arranges the spun yarns Y at equal intervals in the front-rear direction, and carries them out downward.

  The winding unit 3 (yarn winding device) is disposed below the spinning machine 2 and winds a plurality of yarns Y supplied from the spinning machine 2 via the transport unit 4 onto a plurality of bobbins B, respectively. A plurality of packages P are formed. The winding unit 3 includes a main body frame 5, a turret 6, two bobbin holders 7 (winding shaft), a plurality of traverse guides 8, a contact roller 9, and the like.

  The turret 6 is a disk-shaped member, and is provided on the main body frame 5 so as to be rotatable. One end of each of the two bobbin holders 7 (winding shafts) is supported by the turret 6, and a plurality of bobbins B are mounted in series along the axial direction. The plurality of traverse guides 8 are respectively arranged above the plurality of bobbins B mounted on the bobbin holder 7 and traverse the yarn Y wound around the bobbin B. The contact roller 9 is movable in the vertical direction with respect to the main body frame 5, and contacts the bobbin B attached to the bobbin holder 7 when winding the yarn around the bobbin B.

  The winding unit 3 rotates a plurality of bobbins B mounted on the bobbin holder 7 by rotating the bobbin holder 7 by driving a driving motor (not shown), and winds the yarn Y around the rotating bobbins B, respectively. At this time, the yarn Y wound around the bobbin B is traversed in the axial direction of the bobbin B by the traverse guide 8 with a guide 17 described later as a fulcrum, and is wound around the bobbin B. Further, the contact roller 9 rotates while applying a predetermined contact pressure to the package P when winding the yarn around the bobbin B, thereby adjusting the shape of the package P.

  Next, the transport unit 4 will be described. The spinning winder 1 includes a frame 14, two goded rollers 11, 12, a plurality of distribution rollers 13, and the like. The frame 14 is a frame-like member disposed behind the winding unit 3.

  The two goded rollers 11 and 12 are rollers for taking a plurality of yarns Y supplied from the spinning machine 2. The goded rollers 11 and 12 are drive rollers that are rotatably supported by a support member 16 installed on the frame 14 above the main body frame 5 of the winding unit 3 and are driven by a drive motor (not shown). The goded roller 11 is disposed below the spinning machine 2, and the goded roller 12 is disposed above the goded roller 11.

  The plurality of distribution rollers 13 are used to distribute the plurality of yarns Y wound around the downstream side goded roller 12 one by one to the bobbin B attached to the bobbin holder 7 of the winding unit 3. The traverse guide 8 is arranged at equal intervals corresponding to the bobbin B. A plurality of yarns Y conveyed by the goded rollers 11 and 12 are hung on the distribution roller 13 one by one and on a guide 17 disposed immediately below the distribution roller 13. As a result, the plurality of yarns Y are distributed one by one to the plurality of bobbins B, guided by the distribution roller 13 and the guide 17, and conveyed toward the winding unit 3 (traverse guide 8).

  Next, the configuration around the distribution roller 13 will be described. FIG. 3 is a view of the distribution roller 13 of FIGS. 1 and 2 and its peripheral portion viewed from the rear. 4 is a cross-sectional view taken along line IV-IV in FIG.

  Each of the plurality of distribution rollers 13 is supported by a rotating shaft 21 extending in a direction orthogonal to the axis of the bobbin holder 7. A ball bearing 22 is interposed between the distribution roller 13 and the rotating shaft 21. Yes. Here, the ball bearing 22 has a small rotational resistance, and transmits only a small driving force from the rotating shaft 21 to the distribution roller 13. More specifically, the distribution roller 13 in a state where the yarn Y is not hung is transmitted from the rotating shaft 21 to the distribution roller 13 with a minimum driving force required to rotate against the air resistance acting on the distribution roller 13. It has a degree of rotational resistance.

  The rotating shaft 21 is supported by a support member 15 fixed to the frame 14, and two ball bearings 23 arranged in the front and rear are interposed between the rotating shaft 21 and the support member 15. Thereby, the rotating shaft 21 is rotatably supported with respect to the support member 15.

  A pulley 24 is provided at the rear end of the rotating shaft 21. As shown in FIG. 3, a plurality of pulleys 24 provided on the plurality of rotating shafts 21, a pulley 27 attached to the rotating shaft of a single drive motor 26 disposed at one end of the support member 15, and a pulley 24. One endless drive belt 25 is wound around the tension pulley 28 disposed between the two and the driven pulley 29 disposed at the other end of the support member 15.

  As a result, when the drive motor 26 is driven to rotate the pulley 27, the drive belt 25 rotates, and the plurality of pulleys 24 around which the drive belt 25 is wound rotate integrally with the plurality of rotating shafts 21. Then, the rotation (driving force) of the plurality of rotating shafts 21 is transmitted to the distribution roller 13 via the ball bearing 22, whereby the plurality of distribution rollers 13 rotate.

  In the first embodiment, since the plurality of distribution rollers 13 are rotated by the drive motor 26 provided in common to the plurality of distribution rollers 13 as described above, the plurality of distribution rollers 13 are individually driven. There is no need to provide a motor, and the configuration of the apparatus is simplified.

  However, in this case, due to the friction between the drive belt 25 and the pulley 24, the rotational speed of the rotary shaft 21 inevitably varies. However, as described above, the ball bearing 22 has such a small rotational resistance that only a slight driving force is transmitted from the rotary shaft 21 to the distribution roller 13, so that the rotational speed of the rotary shaft 21 varies. Also, the distribution roller 13 follows the yarn Y, rotates at a rotational speed corresponding to the traveling speed of the yarn Y, and rotates relative to the rotating shaft 21. That is, even if the rotational speed of the rotary shaft 21 varies, the distribution roller 13 continues to rotate at a rotational speed corresponding to the traveling speed of the yarn Y, and the rotational speed of the distributing roller 13 corresponds to the traveling speed of the yarn Y. Will not deviate from the rotational speed. Therefore, friction is unlikely to occur between the traveling yarn Y and the distribution roller 13.

  At this time, the distribution roller 13 rotates at a high speed (for example, about 20000 rpm) in accordance with the traveling speed of the yarn Y. However, since the rotating shaft 21 rotates at substantially the same rotational speed as the distribution roller 13, the ball bearing The rotational speed of 22 is small. Therefore, the life of the ball bearing 22 is extended.

  More specifically, when the rotating shaft 21 rotates at the same rotational speed as the distribution roller 13, the distribution roller 13 and the rotating shaft 21 rotate integrally, so that the ball bearing 22 hardly rotates. On the other hand, when there is a difference in rotational speed between the distributing roller 13 and the rotating shaft 21 due to variations in the rotating speed of the rotating shaft 21, the distributing roller 13 and the rotating shaft 21 rotate relative to each other. Rotate. However, since the variation in the rotation speed of the rotation shaft 21 is smaller than the rotation speed of the rotation shaft 21 (for example, 500 rpm or less), the rotation speed of the ball bearing 22 at this time does not rotate the rotation shaft 21. Compared to the case of the shaft, it is sufficiently small. Therefore, the life of the ball bearing 22 is extended.

  Further, since the ball bearing is rotated by receiving the driving force transmitted from the rotating shaft 21 of the distribution roller 13, the distribution roller 13 is difficult to rotate even if the rotational resistance is somewhat increased. In addition, friction is not easily generated between the yarn Y and the distribution roller 13. Therefore, the ball bearing 22 does not need to be maintained so frequently.

  In the present embodiment, when the rotating shaft 21 rotates at a high speed (for example, about 20000 rpm), the ball bearing 23 also rotates at substantially the same rotational speed as the rotating shaft 21. For this reason, if the ball bearing 23 has low durability, the life of the ball bearing 23 is shortened.

  However, in the present embodiment, the ball bearing 23 only needs to be able to rotate the rotating shaft 21 that receives a relatively large driving force from the driving motor 26 and rotates with respect to the support member 15. Further, it can have a large rotational resistance, that is, a large size and a large amount of lubricating oil. As a result, the ball bearing 23 has high durability, and the life of the ball bearing 23 can be extended.

  Further, unlike the bearing described in Patent Document 1, the ball bearing 23 that only needs to be able to rotate the rotating shaft 21 that receives a large driving force from the driving motor 26 and rotates with respect to the support member 15 rotates. It is not required to keep the resistance low, and there is no particular problem even if the rotational resistance fluctuates and becomes slightly larger. Therefore, the maintenance of the ball bearing 23 does not need to be performed so frequently.

[Second Embodiment]
Next, a preferred second embodiment of the present invention will be described. However, about 2nd Embodiment, it demonstrates centering on the part which is different from 1st Embodiment, The description is abbreviate | omitted suitably about the part similar to 1st Embodiment.

  FIG. 5 is a diagram corresponding to FIG. 4 of the second embodiment. In the second embodiment, a plurality of distribution rollers 13 are rotated by a single drive motor 26, drive belt 25, etc., as in the first embodiment, but unlike the first embodiment, the distribution rollers 13 and The ball bearing 22 (see FIG. 4) is not interposed between the rotating shaft 21 and the distribution roller 13 is directly fixed to the rotating shaft 21.

  Also in this case, when the drive motor 26 is driven, the plurality of rotating shafts 21 are rotated as in the above-described embodiment, and thereby the plurality of distribution rollers 13 fixed to the plurality of rotating shafts 21 are rotated. Therefore, it is not necessary to provide a drive motor for each of the plurality of distribution rollers 13, and the configuration of the apparatus is simplified.

  Further, in this case, unlike the first embodiment, since there is no ball bearing 22 having a lower rotational resistance and lower durability than the ball bearing 23, the maintenance frequency is further increased than in the first embodiment. Can be reduced.

  However, in the case of the second embodiment, since the ball bearing 22 is not interposed between the distribution roller 13 and the rotating shaft 21, as described above, when the rotational speed of the rotating shaft 21 varies. The distribution roller 13 also varies in rotational speed. For this reason, the rotational speed of the distribution roller 13 may deviate from the rotational speed corresponding to the traveling speed of the yarn Y, and there is a possibility that some friction occurs between the yarn Y and the distribution roller 13.

[Third Embodiment]
Next, a preferred third embodiment according to the present invention will be described. However, the third embodiment will be described with a focus on the differences from the first and second embodiments, and the description of the same configuration as the first and second embodiments will be omitted as appropriate.

  6 and 7 are views corresponding to FIGS. 3 and 4 of the third embodiment, respectively. In the first and second embodiments, the plurality of distribution rollers 13 are rotated by a single drive motor 26 (see FIG. 4). However, in the third embodiment, unlike these, Each of the drive motors 31 is individually attached. That is, in the third embodiment, a plurality of drive motors 31 are individually provided for the plurality of distribution rollers 13, and the plurality of distribution rollers 13 are individually driven by the plurality of drive motors 31. In the third embodiment, similarly to the second embodiment, the ball bearing 22 (see FIG. 4) is not interposed between the distribution roller 13 and the rotary shaft 21, and the distribution roller 13 is not connected to the rotary shaft 21. It is fixed directly to.

  In the first and second embodiments, the rotational speed of the rotary shaft 21 varies due to friction between the drive belt 25 (see FIG. 4) and the pulley 24 (see FIG. 4). In the case of the third embodiment, Since the plurality of rotating shafts 21 are individually rotated by the plurality of drive motors 31, the rotational speed variation of the rotating shaft 21 unlike the first and second embodiments hardly occurs. The rotation speed can be accurately set to a rotation speed corresponding to the traveling speed of the yarn Y, and friction is hardly generated between the yarn Y and the distribution roller 13.

  Next, modified examples in which various changes are made to the first to third embodiments will be described. However, the description of the same configuration as in the first to third embodiments is omitted as appropriate.

  In the first and second embodiments, all the distribution rollers 13 are rotated by one drive motor 26, but the present invention is not limited to this. For example, one drive motor 26, a drive belt 25, and the like are provided for the plurality of distribution rollers 13 disposed in the substantially right half of the spinning winder 1, and the plurality of distribution rollers disposed in the substantially left half. The number of drive motors provided in common to the plurality of distribution rollers 13 may be two or more, such as one drive motor 26 and drive belt 25 provided for the roller 13.

  Further, in the third embodiment, the ball bearing 22 (see FIG. 4) is not interposed between the distribution roller 13 and the rotating shaft 21, and the distribution roller 13 is directly fixed to the rotating shaft 21, However, the present invention is not limited thereto, and even when the drive motor 31 is individually provided for the distribution roller 13, the ball bearing 22 may be interposed between the distribution roller 21 and the rotary shaft 13.

  In the first and second embodiments, an example in which the plurality of distribution rollers 13 are rotated by a drive motor 26, a drive belt 25, and the like that are provided in common to the plurality of distribution rollers 13 will be described. In the embodiment, the example in which the plurality of distribution rollers 13 are rotated by the drive motors 31 individually provided for the plurality of distribution rollers 13 has been described, but the plurality of distribution rollers 13 may be driven by other mechanisms. .
