Description

  The present invention relates to a yarn joining device included in a yarn winding machine.

  A yarn winding machine that winds a yarn around a bobbin to form a package is known. An example of this type of yarn winding machine is a spinning machine disclosed in Patent Document 1. As described in Patent Document 1, this spinning machine includes a spinning device that generates a spun yarn by twisting a fiber bundle, and a winding that forms a package by winding the spun yarn generated by the spinning device onto a bobbin. A take-off device is provided.

  The spinning machine of Patent Document 1 includes a yarn splicing carriage that connects (yields) the yarn on the spinning device side and the yarn on the package side when the spun yarn between the spinning device and the package is in a split state. . The yarn splicing carriage includes a yarn splicing device for connecting the yarn on the spinning device side and the yarn on the package side.

  Thus, during the yarn splicing operation, the yarn path is bent, so that the spun yarn between the spinning device and the package is longer than that during normal winding. For this reason, when the yarn gathering lever is opened after the yarn splicing operation is finished, the spun yarn is slackened for a long time. As a result, the yarn may be wound around the package while being slackened or in a crimped state.

  Further, when the yarn is slack in this way, the slack yarn may be caught by surrounding members, which may cause a problem. For example, in the spinning machine described in Patent Document 1, a rotating slack eliminating roller is provided between the spinning device and the winding device. If the slack of the yarn occurs when rewinding, the yarn may get entangled with the rotating slack eliminating roller. Moreover, the winding device of the spinning machine disclosed in Patent Document 1 includes a traverse guide that is driven to reciprocate. If slack in the yarn occurs when rewinding is resumed, the slack yarn may be caught by the traverse guide and the yarn may break.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a yarn winding machine that eliminates the slack of yarn that occurs at the end of yarn splicing.

And a capture section) 13 as main components. Each spinning unit 2 produces the spun yarn 10 by spinning the fiber bundle 8 sent from the draft device 7 by the spinning device 9, and winds the spun yarn 10 around the bobbin 48 by the winding device 13. The bobbin 48 around which the spun yarn 10 is wound is referred to as a package 45. In the present specification, “upstream” and “downstream” mean upstream and downstream in the traveling direction of the fiber bundle 8 and the spun yarn 10 during normal winding. Also, during normal winding, the spun yarn 10 between the spinning device 9 and the winding device 13 is in a continuous state, and the package 45 is driven to rotate at a substantially constant peripheral speed so that the spun yarn 10 is substantially The state where it is wound at a constant speed shall be said.

The distal end of the link rod 64 is connected to the second support arm 62. A reverse rotation roller advance / retreat air cylinder 66 is attached to the link rod 64, and the link rod 64 can be rotated by the advance / retreat of the reverse rotation roller advance / retreat air cylinder 66.

  As described above, the first support arm 61, the second support arm 62, and the link rod 64 constitute a link mechanism. The reverse rotation roller 63 at the front end of the second support arm 62 can be moved forward and backward by controlling expansion and contraction of the reverse rotation roller advance / retreat air cylinder 66 connected to the link mechanism. As a result, the reverse rotation roller 63 is moved between the “retracted position” (for example, the position shown in FIG. 2) that does not contact the package 45 and the “contact position” (for example, the position shown in FIG. 5) that contacts the package 45. Can be moved. The operation of the reverse rotation roller advance / retreat air cylinder 66 is controlled by the cart controller.

  Next, the yarn joining operation by the yarn joining cart 3 will be described. This yarn splicing operation is performed in a spinning unit 2 when the spun yarn 10 between the spinning device 9 and the package 45 is in a split state for some reason.

  In a spinning unit 2, for example, when the spun yarn 10 between the spinning device 9 and the package 45 is in a divided state as shown in FIG. 4, the unit controller of the spinning unit 2 drives the cradle arm 71 to swing, Control is performed so as to separate the package 45 from the winding drum 72, and a brake mechanism (not shown) provided in the winding device 13 is operated. As a result, the package 45 stops rotating.

  Subsequently, the unit controller transmits a control signal to the yarn joining cart 3. The yarn joining cart 3 that has received the control signal travels to the spinning unit 2 on the yarn joining cart traveling rail 41 and stops. When the yarn joining cart 3 travels between the spinning units 2, the moving means 30 retracts the yarn joining device 43 to the retracted position.

  When the yarn splicing cart 3 stops at the target spinning unit 2, the cart control unit rotates the suction pipe 44 and the suction mouth 46, respectively, as shown in FIG. Aspirate the yarn end and catch it.

  Further, at this time, the carriage control unit controls the reverse rotation roller advance / retreat air cylinder 66 to advance the reverse rotation roller 63 to the contact position and bring the reverse rotation roller 63 into contact with the package 45. Further, the cart controller drives the reverse rotation roller 63 to rotate in the direction opposite to the take-up drum 72 by the reverse rotation roller drive motor. Thereby, the package 45 is rotationally driven in a direction opposite to the winding direction (hereinafter, unwinding direction). In this state, the spun yarn 10 on the surface of the package 45 is sucked by the suction mouse 46, whereby the spun yarn 10 is pulled out of the package 45 and captured by the suction mouse 46.

  Subsequently, the carriage control unit rotates the suction pipe 44 and the suction mouth 46 in a state in which the spun yarn 10 is captured in opposite directions so that the captured spun yarn 10 faces the front side of the yarn splicing device 43. Guide to position (state of FIG. 6). When the guide of the spun yarn 10 by the suction pipe 44 and the suction mouth 46 is finished, the carriage control unit stops the rotation of the reverse rotation roller 63. As a result, the package 45 is stationary.

  Subsequently, the moving means 30 extends the air cylinder 38 and moves the yarn joining device 43 in a direction approaching the yarn path to advance to the yarn joining position. When the yarn joining device 43 advances to the yarn joining position, the spun yarn 10 on the spinning device 9 side captured by the suction pipe 44 and the spun yarn 10 on the package 45 side captured by the suction mouth 46 become a yarn. It is introduced into the relay device 43 (state shown in FIG. 7). Further, as shown in FIG. 7 and the like, the joint monitor 47 is arranged so that the spun yarn 10 is introduced into the joint monitor 47 when the moving means 30 advances the yarn joining device 43 to the yarn joining position. ing. Therefore, the spun yarn 10 can be inspected by the joint monitor 47 by advancing the yarn joining device 43 to the yarn joining position.

  When the yarn joining device 43 advances to the yarn joining position, the carriage control unit appropriately controls the electric motor 60 to rotate the yarn moving lever 96 to contact the spun yarn 10. As a result, the spun yarn 10 between the package 45 and the suction mouth 46 and the spun yarn 10 between the spinning device 9 and the suction pipe 44 are bent by the yarn shifting lever 96, respectively. The road is regulated. The yarn holding lever 96 bends the spun yarn 10 to a position where the spun yarn 10 can be gripped by the clamp portion 97 (state of FIG. 8). In this state, the carriage control unit appropriately controls the electric motor 60 and closes the clamp unit 97, thereby holding the spun yarn 10 by the clamp unit 97.

  Subsequently, the carriage control unit starts to eject compressed air into the untwisting pipe 82. Thereby, in the untwisting pipe 82, while the air flow which goes to the back side (drawing right side of FIG. 8) of the yarn splicing device 43 generate | occur | produces, the front side (left side of FIG. 8 drawing) of the said untwisting pipe 82 A suction air flow is generated in the opening. Before and after this, the cart controller operates the cutter 92 by appropriately controlling the electric motor 60, and the spun yarn 10 between the suction pipe 44 and the yarn splicing device 43, and the suction mouth 46 and the yarn splicing device. Each of the spun yarns 10 between 43 is cut. The yarn ends formed by the cutting are sucked by the untwisting pipe 82 and drawn into the untwisting pipe 82. The drawn yarn ends are untwisted and untwisted by the action of the air flow in the untwisting pipe 82 (FIG. 9).

  When the yarn end untwisting is completed, the carriage control unit terminates the ejection of the compressed air into the untwisting pipe 82. Further, the carriage controller further controls the electric motor 60 to further bend the yarn path of the spun yarn 10 by the yarn shifting lever 96 and the yarn pressing lever 98, and drag the untwisted yarn end from the untwisted pipe 82. . The yarn ends drawn from the untwisting pipe 82 are set in a state where they are overlapped with each other in the yarn joining hole 90 of the yarn joining nozzle 94 (FIG. 10). In this state, by jetting compressed air into the yarn joining hole 90, a swirling flow is generated in the yarn joining hole 90, and the fibers are twisted. As a result, the yarn end of the spun yarn 10 on the spinning device 9 side and the yarn end of the spun yarn 10 on the package 45 side are twisted and joined to form a seam.

  When the seam is formed, the carriage control unit stops the ejection of air to the yarn joining hole 90. Further, the carriage control unit appropriately controls the electric motor 60 to open the clamp unit 97 and release the held spun yarn 10. Next, the unit controller of the spinning unit 2 swings the cradle arm 71 to bring the outer peripheral surface of the package 45 into contact with the rotating winding drum 72 (state shown in FIG. 11). With the above configuration, the package 45 in contact with the winding drum 72 resumes rotation in the winding direction, and winding of the spun yarn 10 is started.

  In this embodiment, when the carriage control unit opens the clamp unit 97 to release the spun yarn 10, the yarn path regulating members (yarn shifting lever 96 and yarn holding lever 98) are kept stationary without rotating, The electric motor 60 is controlled so that the yarn path regulating member maintains the bent state of the spun yarn 10. Therefore, in the present embodiment, the winding of the spun yarn 10 is resumed while the yarn path is regulated. Temporarily, at the start of winding of the spun yarn 10, the yarn path regulating members (yarn feeding lever 96 and yarn holding lever 98) are rotated so that the yarn path regulating member is not in contact with the spun yarn 10 and is wound. If it is resumed, the spun yarn 10 that has been bent by the yarn path regulating member is in a free state, and as shown in FIG.

  In this regard, in the present embodiment, as described above, when the winding is resumed, the spun yarn 10 is maintained in a state in which the spun yarn 10 is bent by the yarn passage regulating member. 10 windings can be resumed. Thereby, the slack at the time of resuming winding of the spun yarn 10 can be prevented.

  In the present embodiment, the yarn accumulating device 12 is disposed between the spinning device 9 and the yarn joining device 43. During the yarn joining operation, the winding of the spun yarn 10 by the winding device 13 is interrupted, but the spinning of the spun yarn 10 by the spinning device 9 is continued. Therefore, the yarn accumulating device 12 is configured to wind the spun yarn 10 spun from the spinning device 9 around the yarn accumulating roller 14 and temporarily store it. On the other hand, in the present embodiment, the spinning device 9 is an air spinning type spinning device. The pneumatic spinning device is capable of high-speed spinning and spins the spun yarn 10 at high speed. For this reason, during the yarn joining operation, the spun yarn 10 spun at a high speed from the spinning device 9 is stored in the yarn storage device 12 one after another, so that the time until the storage limit of the yarn storage device 12 is exceeded is as follows. short. That is, in the spinning machine 1 of this embodiment provided with the air spinning type spinning device 9, there is a situation in which the winding of the spun yarn 10 cannot be interrupted for a long time during the yarn splicing operation.

  Therefore, in a conventional spinning machine equipped with a pneumatic spinning device, the yarn path restriction by the yarn path regulating member is released immediately after the yarn splicing operation is completed in order to resume the winding of the spun yarn 10 at the earliest possible stage. I was doing it. And when the regulation of the yarn path was released, the winding of the spun yarn 10 was resumed. Thus, in the conventional spinning machine, since the winding was started after the restriction of the yarn path was released, the slack of the spun yarn 10 occurred.

  By the way, although the yarn path regulating member (the yarn shifting lever 96 and the yarn holding lever 98) is in contact with the spun yarn 10, it does not mean that the spun yarn 10 is gripped. For this reason, even if the yarn path of the spun yarn 10 is regulated by the yarn path regulating member (a state where the spun yarn 10 is bent), the spun yarn 10 can be run. The spinning machine 1 of the present embodiment pays attention to this point, and after the end of the yarn splicing operation by the yarn splicing device 43, at the stage where the holding of the spun yarn 10 by the clamp part 97 is released, the yarn path restriction by the yarn path regulating member is performed. Thus, the winding of the spun yarn 10 is resumed while maintaining the state (while maintaining the bent state of the spun yarn 10). By configuring in this way, the winding of the spun yarn 10 can be resumed when the gripping of the spun yarn 10 by the clamp portion 97 is released. Thereby, winding can be resumed at an early stage after the end of the yarn splicing operation while restricting the yarn path of the spun yarn 10. Therefore, the spun yarn 10 on the yarn storage device 12 can be prevented from exceeding the storage limit of the yarn storage device 12.

  When the winding of the spun yarn 10 is resumed as described above, the seam 99 formed by the yarn splicing device 43 passes through the seam monitor 47 as shown in FIG. At this time, the seam 99 is inspected by the seam monitor 47. The cart control unit determines the quality of the joint 99 based on the inspection result by the joint monitor 47. Therefore, it can be said that the cart control unit is a determination unit. For example, when the seam 99 is a defective seam that does not satisfy the dimensional conditions such as a predetermined thickness and length, the yarn joining cart 3 cuts and removes the defective seam with a cutter (not shown) and uses the yarn joining device 43. Repeat the splicing. According to the configuration of the present embodiment, it is possible to prevent sagging immediately after resuming the winding of the spun yarn 10, and thus it is possible to prevent the spun yarn 10 from passing through the joint monitor 47 in a slack state. Therefore, the seam monitor 47 can inspect the quality of the seam 99 with high accuracy.

  When the inspection of the seam 99 by the seam monitor 47 is completed, the cart control unit appropriately controls the electric motor 60 to release the restriction of the yarn path by the yarn path regulating member (the yarn shifting lever 96 and the yarn holding lever 98). . At this time, the carriage control unit appropriately controls the electric motor 60, so that the yarn path regulating member (yarn shifting lever 96 and yarn holding lever 98) can maintain the bent state of the spun yarn 10 at a speed at which the yarn can be controlled. The road regulating member is rotated. That is, the carriage control unit slowly moves the yarn path regulating member. That is, if the yarn path regulating member is quickly moved, the yarn path regulating member is separated from the spun yarn 10 and consequently the spun yarn 10 cannot be bent by the yarn path regulating member (spun yarn 10). Becomes free), and sagging occurs in the spun yarn 10. By slowly moving the yarn path regulating member as described above, the yarn path of the spun yarn 10 is regulated by the yarn path regulating member (while maintaining the bent state of the spun yarn 10), while the spun yarn 10 is concerned. Can be released, so that sagging of the spun yarn 10 can be prevented.

  As described above, in the conventional spinning machine, in order to resume the winding of the spun yarn 10 as soon as possible, it is considered that the yarn path regulation by the yarn path regulating member should be released as soon as possible. It was. However, in the present embodiment, by changing the way of thinking, the winding of the spun yarn 10 is resumed while the yarn path is regulated by the yarn path regulating member. Therefore, it is not necessary to quickly release the yarn path by the yarn path regulating member. Therefore, the yarn path regulating member can be moved slowly over a certain period of time. Thereby, the state where the yarn path is regulated by the yarn path regulating member (the state where the spun yarn 10 is bent) can be reliably maintained, and the spun yarn 10 can be reliably prevented from sagging.

  When the yarn path regulating member (yarn shifting lever 96 and yarn holding lever 98) is rotated and the yarn path of the spun yarn 10 returns to the yarn path at the time of normal winding (that is, bent by the yarn path regulating member). When the yarn path of the spun yarn 10 returns to the straight state), the yarn path regulating member is separated from the spun yarn 10. Thereby, the spun yarn 10 can be released from the yarn path regulating member. When the spun yarn 10 is released from the yarn path regulating member, the moving means 30 moves the yarn joining device 43 to the retracted position. Thereby, the yarn splicing cart 3 can travel and can travel to other spinning units 2.

  As described above, the spinning machine 1 of the present embodiment includes the winding device 13, the spinning device 9, the yarn joining device 43, the yarn path regulating member (the yarn shifting lever 96 and the yarn presser lever 98), A cart control unit. The winding device 13 winds the spun yarn 10 around the package 45. The spinning device 9 supplies the spun yarn 10 to the winding device 13. The yarn joining device 43 joins the spun yarn 10 between the spinning device 9 and the package 45. The yarn path regulating member is movable between a position where the spun yarn 10 is bent by contacting the spun yarn 10 and a position where the spun yarn 10 is opened. At the time of yarn splicing, the carriage control unit brings the yarn path regulating member into contact with the spun yarn 10 to bend the spun yarn 10, and after the splicing is completed, at least the winding device 13 winds the spun yarn 10. Until the take-off starts, the spun yarn 10 is controlled to be bent by the yarn path regulating member.

  In this way, by starting the winding of the spun yarn 10 with the yarn path regulated by the yarn path regulating member, it is possible to prevent the spun yarn 10 from sagging immediately after the end of yarn splicing.

  The spinning machine 1 according to the present embodiment includes a seam monitor 47 that inspects the quality of the seam 99 formed by the yarn splicing in the yarn splicing device 43. The carriage control unit performs control so that the yarn path regulating member maintains the bent state of the spun yarn 10 at least until the seam 99 passes through the seam monitor 47 after the yarn splicing by the yarn splicing device 43 is completed. To do.

  Thereby, the seam monitor 47 can inspect the seam 99 in a state where the yarn path is regulated by the yarn path regulating member. That is, since the spun yarn 10 does not sag when the seam monitor 47 inspects the seam 99, the inspection accuracy of the seam 99 can be improved.

  The spinning machine 1 of the present embodiment is configured as follows. In other words, the spinning machine 1 further includes a clamp portion 97 that holds the spun yarn 10 when the yarn is spliced by the yarn splicing device 43. After the yarn splicing by the yarn splicing device 43 is completed, the carriage control unit releases the spun yarn 10 held by the clamp unit 97, and the spun yarn by the winding device 13 in a state where the spun yarn 10 is bent by the yarn path regulating member. Control is performed to start winding the yarn 10.

  That is, since the spun yarn 10 can run by releasing the spun yarn 10 held by the clamp portion 97, winding of the spun yarn 10 can be started. On the other hand, when the winding start is started, the yarn path regulation by the yarn path regulating member is continued to prevent the spun yarn 10 from sagging.

  In the spinning machine 1 of the present embodiment, the spinning device 9 is an air spinning device that generates a spun yarn 10 by twisting the fiber bundle 8 by a swirling airflow.

  That is, since the air spinning type spinning device 9 generates the spun yarn 10 at a high speed, fluctuations in the yarn path tend to affect the spinning of the spinning device 9. For this reason, the quality of the spun yarn 10 produced | generated can be improved by preventing the slack of the spun yarn 10 immediately after the end of yarn splicing.

  In the spinning machine 1 of the present embodiment, the carriage control unit spins the yarn path regulating member after the yarn splicing by the yarn splicing device 43 ends at least until the winding of the spun yarn 10 in the winding device 13 starts. Control is performed such that the yarn 10 is kept stationary in a bent state, and then the spun yarn 10 is moved to a release position.

  In this way, by temporarily stopping the yarn path regulating member, the state in which the spun yarn 10 is bent by the yarn path regulating member can be reliably maintained, so that the spun yarn 10 is slackened. It can be surely prevented.

  In the spinning machine 1 of the present embodiment, the carriage control unit bends the spun yarn 10 when the yarn path regulating member moves from a position where the spun yarn 10 is bent to a position where the spun yarn 10 is released. The yarn path regulating member is controlled to move at a speed that can maintain the state.

  That is, when the spun yarn 10 is released, the yarn path regulating member is slowly moved. As a result, the yarn path regulating member can be moved while regulating the yarn path by the yarn path regulating member, so that the spun yarn 10 is slackened when the yarn path regulating member releases the spun yarn 10. Can be prevented.

  The spinning machine 1 of the present embodiment is disposed between the spinning device 9 and the winding device 13 in the traveling direction of the spun yarn 10, and winds the spun yarn 10 around the outer periphery of the rotating yarn accumulating roller 14 to temporarily store the spun yarn 10. A yarn storage device 12 is provided. The yarn joining device 43 performs yarn joining between the yarn accumulating device 12 and the winding device 13 in the traveling direction of the spun yarn 10.

  That is, according to the configuration of the present invention, it is possible to prevent sagging of the spun yarn 10 at the time of splicing, so that the spun yarn 10 can be prevented from being entangled with the rotating yarn accumulating roller 14. Therefore, the spun yarn 10 can be appropriately stored by the yarn storage device 12.

  The spinning machine 1 of the present embodiment includes a traverse device 75 that traverses the spun yarn 10 wound around the package 45 by a traverse guide 76 that reciprocates.

  That is, according to the configuration of the present invention, it is possible to prevent sagging of the spun yarn 10 at the time of yarn splicing, and thus it is possible to prevent the spun yarn 10 that is slackened from the reciprocating traverse guide 76 from being caught and causing yarn breakage. Therefore, traversing of the spun yarn 10 by the traverse device 75 can be performed appropriately.

  The spinning machine 1 according to this embodiment includes a plurality of spinning units 2 and a yarn splicing cart 3. Each spinning unit 2 includes a spinning device 9 and a winding device 13. The yarn splicing carriage 3 includes a yarn splicing device 43 and can travel between the plurality of spinning units 2 and stops in the vicinity of the spinning unit 2 in which the spun yarn 10 has been cut off. On the other hand, the yarn joining device 43 performs yarn joining.

  Thus, by providing the yarn joining cart 3 that travels with the yarn joining device 43 mounted thereon, the overall structure of the spinning machine 1 is simplified as compared with the configuration in which the yarn joining device 43 is provided in each spinning unit 2. Cost can be reduced.

  The preferred embodiment of the present invention has been described above, but the above configuration can be modified as follows, for example.

  In the above embodiment, the yarn splicing cart 3 includes the yarn splicing device 43. However, instead of this, the yarn splicing cart 3 may be configured as follows. That is, the spinning unit 2 includes a winding device 13, a spinning device 9, a yarn joining device 43, a yarn path regulating member (yarn shifting lever 96 and yarn holding lever 98), and a carriage control unit. . The winding device 13 winds the spun yarn 10 around the package 45. The spinning device 9 supplies the spun yarn 10 to the winding device 13. The yarn joining device 43 joins the spun yarn 10 between the spinning device 9 and the package 45. The yarn path regulating member is movable between a position where the spun yarn 10 is bent by contacting the spun yarn 10 and a position where the spun yarn 10 is opened. At the time of yarn splicing, the carriage control unit brings the yarn path regulating member into contact with the spun yarn 10 to bend the spun yarn 10, and after the splicing is completed, at least the winding device 13 winds the spun yarn 10. Until the take-off starts, the spun yarn 10 is controlled to be kept bent by the yarn path regulating member.

  In this way, each spinning unit 2 may be configured to include the yarn joining device 43.

  In the above-described embodiment, when the yarn path regulating members (yarn shifting lever 96 and yarn holding lever 98) release the spun yarn 10, the carriage control unit appropriately controls the electric motor 60 to slowly move the yarn path regulating member. I decided to move it. On the other hand, when the yarn path of the spun yarn 10 is regulated by the yarn path regulating member (when the yarn path regulating member is moved in a direction in contact with the spun yarn 10), it is necessary to move the yarn path regulating member slowly. Is low. Therefore, for example, when opening the spun yarn 10 by the yarn path regulating member, it is preferable to control the electric motor 60 to be driven later than when regulating the yarn path of the spun yarn 10.

  In the above-described embodiment, the carriage control unit controls the yarn path regulating member (yarn shifting lever 96 and yarn holding lever 98), the clamp unit 97, the cutter 92, and the like by appropriately controlling the electric motor 60. This is to appropriately control the moving speed, moving timing, etc. of the yarn path regulating member (yarn moving lever 96 and yarn holding lever 98) by changing and controlling the driving speed and driving direction of the electric motor 60 as needed. Point to. However, the present invention is not limited to this. For example, the electric motor 60 may be controlled to be driven at a constant driving speed. That is, if the cam shape of the cam mechanism is appropriately set, the yarn path regulating member and the like are controlled to move at an appropriate speed and timing by simply driving the electric motor 60 at a constant driving speed. Is possible.

  However, the mechanism for moving the yarn path regulating member (the yarn shifting lever 96 and the yarn holding lever 98) is not limited to the cam mechanism, and an appropriate configuration can be adopted.

  In the above-described embodiment, the yarn path regulating members (yarn shifting lever 96 and thread holding lever 98) are kept stationary until the joint 99 passes through the seam monitor 47, and then the yarn path regulating member is slowly ( It was assumed to be moved while maintaining the state where the yarn path was regulated. However, the present invention is not limited to this, and the yarn path regulating member may be controlled to move slowly (while maintaining the state in which the yarn path is regulated) immediately after the gripping of the spun yarn 10 by the clamp portion 97 is released. . Even in this case, the yarn path of the spun yarn 10 can be regulated to prevent the spun yarn 10 from sagging.

  In the above embodiment, the yarn path restricting member opens the spun yarn 10 after the joint 99 passes through the joint monitor 47. Whether or not the joint 99 has passed through the joint monitor 47 can be known based on the detection result of the joint monitor 47. Therefore, it may be configured to cancel the restriction of the yarn path of the spun yarn 10 by the yarn path regulating member based on the detection result of the joint monitor 47. However, the present invention is not limited to this, and after the winding of the spun yarn 10 by the winding device 13 is resumed, a sufficient time for the seam 99 to pass through the seam monitor 47 has passed, so that the yarn of the spun yarn 10 by the yarn path regulating member You may comprise so that the restriction | limiting of a road may be cancelled | released.

  In the above embodiment, the spun yarn 10 is pulled out from the spinning device 9 by rotating the yarn accumulating roller 14 of the yarn accumulating device 12. Instead of this, for example, as described in Japanese Patent Application Laid-Open No. 2005-220484, a yarn feeding device that pulls out the spun yarn from the spinning device by sandwiching and rotating the spun yarn between the delivery roller and the nip roller may be provided. good.

  The movement of the joint monitor 47 may be performed independently of the yarn joining device 43. However, since the configuration of the spinning machine 1 can be simplified, it is desirable to move the joint monitor 47 and the yarn joining device 43 simultaneously.

  The configuration for inspecting the joint 99 formed by the yarn joining device 43 may be omitted. In this case, the joint monitor 47 can be omitted.

  In the above-described embodiment, the traveling direction of the spun yarn 10 is directed from the top to the bottom in the height direction, but the traveling direction of the spun yarn 10 is not particularly limited. For example, the spun yarn 10 travels from the bottom to the top. The present invention can also be applied to the configuration.

  In FIG. 2 and the like, the yarn path of the spun yarn 10 is substantially vertical, but the present invention is not limited to this. For example, when the winding device 13 is arranged on the back side of the spinning unit 2 with respect to the position shown in FIG. 2, the yarn path is formed to be inclined from the front side to the back side.

  In FIG. 1 and the like, the spinning machine 1 includes one yarn splicing cart 3, but a plurality of yarn splicing carts 3 may be provided according to the number of spinning units 2.

  In the above embodiment, the take-up drum 72 is driven in common by the plurality of spinning units 2. However, the present invention is not limited to this, and the winding drum 72 may be driven individually by each spinning unit 2. In this case, the rotational speed and direction of the take-up drum 72 can be made different for each spinning unit 2, so that the package 45 is rotated in the reverse direction by rotating the take-up drum 72 in the reverse direction. May be. In this case, the reverse rotation roller 63 can be omitted.

  A configuration in which the yarn joining device 43 is movable with respect to the yarn path may be omitted.

  The spinning device is not limited to the pneumatic spinning device, and the configuration of the present invention can be applied to a spinning machine including another type of spinning device. The configuration of the present invention can be widely applied not only to a spinning machine but also to other types of yarn winding machines such as an automatic winder.
