Therefore, a conventional winding device or the like is provided with a mechanism for applying tension to the yarn member. Such a mechanism is disclosed in Patent Documents 1 and 2, for example. Patent Document 1 discloses a device (synthesizing machine) that spins a plurality of yarns, joins them into one, and winds them up. A member for applying tension to each yarn is provided for each yarn path of each yarn. The yarns are combined while adjusting the tension of each yarn. Patent document 2 is disclosing about the apparatus which provides tension | tensile_strength to each of several wire cords (thread member), measures the tension | tensile_strength of each wire cord separately, and uses wire cord according to the measured tension | tensile_strength. It is controlled to give an appropriate tension.

  However, in Patent Document 1, it is very difficult to keep applying tension evenly when applying tension to each of the plurality of yarn members. Moreover, in patent document 2, in order to provide tension | tensile_strength equally, the apparatus which measures the tension | tensile_strength of several thread members, and the apparatus for controlling tension | tensile_strength according to a measured value are provided, and a structure is provided. It is complex and expensive.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a winding device that can continuously apply tension to each yarn member with a simple configuration. To do.

  A winding device according to the present invention is a winding device that individually winds a plurality of yarn members, and is arranged in parallel with a roller group composed of a plurality of rollers that respectively apply tension to each yarn member. And a plurality of tension members that apply a tensile force to the roller group, and an abnormality detection sensor that detects an abnormality of each yarn member. This winding device loses or reduces the tensile force of at least one tension member when an abnormality of the yarn member is detected by the abnormality detection sensor.

  According to this, since tension force is applied to the roller group by the plurality of tension members, it is possible to evenly apply tension to each yarn member. In addition, when an abnormality occurs in the yarn member due to the yarn member being cut or the like, the roller group is used to lose or reduce the tensile force of at least one of the tensile members arranged in parallel. The tensile force acting on the yarn can also be reduced, and the tension on the remaining yarn members can be made constant.

  Therefore, since it is possible to continue to apply an equal tension to each yarn member in both normal and abnormal conditions, it is possible to stably wind a plurality of yarn members.

  And a rotation member coupled to at least one tension member and capable of rotating against the tensile force of the tension member, and a rotation restriction device for restricting rotation of the rotation member. By restricting the rotation of the rotating member at a predetermined position, a tensile force is generated in the tensile member. On the other hand, when an abnormality of the yarn member is detected by the abnormality detection sensor, the rotation restricting device releases the restriction of the rotating member. By doing so, it is preferable to lose or reduce the tensile force of the tensile member connected to the rotating member. According to this, the tensile force of the tension member can be lost or reduced by the mechanical configuration.

  The tension member is preferably a spring member. According to this, the tensile force of the tension member can be applied to the yarn member with a simple configuration.

  The roller group is composed of a fixed roller and a moving roller, and it is preferable to apply tension to each yarn member by moving the moving roller in the direction away from the fixed roller based on the tensile force of the tension member. According to this, the tensile force of the tension member can be applied to the yarn member with a simple configuration.

  Moreover, it is preferable to provide a rotation mechanism that rotates the moving roller in the direction away from the fixed roller. According to this, the tensile force of a tension member can be made to act with a mechanical structure.

  The tension member is preferably an air cylinder that applies a tensile force when supplied with air. According to this, the tensile force can be easily applied by supplying air, and the tensile force can be easily lost or reduced by stopping the supply of air.

  According to the present invention, a tensile force is applied to the roller group by a plurality of tension members, so that the tension can be evenly applied to each yarn member in each roller, and the yarn member can be cut, for example. When an abnormality occurs in a member, in order to lose or reduce the tensile force of at least one of the plurality of tensile members arranged in parallel, the tensile force acting on the roller group is also reduced, and the remaining yarn The tension on the strip member can be made constant.

  Therefore, since a uniform tension can be continuously applied to each yarn member at both normal times and abnormal times, a winding device capable of stably winding a plurality of yarn members is provided. It becomes possible.

The winding device includes a tension applying device 1 that applies tension when winding a plurality of yarn members (hereinafter referred to as “yarns”) individually. In addition, although the thread here demonstrates as what is a tape-shaped fiber bundle which has a flat cross-sectional shape, if it is a thread member, arbitrary things may be sufficient.

  The tension applying device 1 is provided in a process until the yarn is wound around a bobbin 70 described later. As shown in FIG. 1, the tension applying device 1 includes a roller group 10 in which a plurality of rollers are connected to each other, a tension device 20 that applies a tensile force to the roller group 10, and a rotating member 30 that is rotatably provided.

The yarns L1 and L2 are conveyed in the directions of arrows shown in the vicinity of each in FIG. The yarns L1 and L2 that have passed through the tension applying device 1 are wound around a bobbin 70 shown in FIG. The bobbin 70 includes winding portions 72 and 73 for simultaneously winding the two yarns L1 and L2 at both ends of one winding shaft 71. Although not shown, a traversing machine for traversing each of the yarns L1 and L2 is provided in the upper part of FIG. 2, and the yarns L1 and L2 are evenly distributed by the winding unit 72 of the bobbin 70 by the traversing machine. , 73.

  As shown in FIG. 1, each of the roller groups 10 is formed in a disk shape, and is a fixed roller (hereinafter referred to as “first roller”) 11 and a movable roller (hereinafter referred to as “second roller”) that are rotatable in the same plane direction. 4, a fixed roller (hereinafter referred to as “third roller”) 13, and a moving roller (hereinafter referred to as “fourth roller”) 14. The first roller 11 and the second roller 12 convey the yarn L <b> 1. Then, the third roller 13 and the fourth roller 14 convey the yarn L2. Further, in the vicinity of the roller group 10, a member (hereinafter referred to as “support member”) capable of supporting various components is provided.

  The first roller 11 is fixed to a support member (not shown) and has a rotation shaft 11a. Accordingly, the first roller 11 rotates while being fixed at a predetermined position. A long first support arm 15 is provided at a position adjacent to the first roller 11. The first support arm 15 has a rotation shaft at the same position as the rotation shaft 11 a and can rotate in the same plane direction as the first roller 11.

  The second roller 12 has a rotation shaft 12 a and is provided at the other end of the first support arm 15. Accordingly, the second roller 12 can move as the first support arm 15 rotates, and rotates at the tip of the first support arm 15.

  In the above configuration, as shown in FIG. 1, the yarn L <b> 1 conveyed from above is turned from the left side of the second roller 12 to the lower side and hung to the right side, and from the left side of the first roller 11 to the upper side. Therefore, the second roller 12 can apply a downward tension to the yarn L1.

  The third roller 13 has a rotation shaft 13 a and is fixed to a support member (not shown) on the lower side of the first roller 11. Therefore, the third roller 13 rotates while being fixed at a predetermined position. In addition, a long second support arm 17 is provided at a position adjacent to the third roller 13. The second support arm 17 has a rotation shaft at the same position as the rotation shaft 13 a and can rotate in the same plane direction as the third roller 13. Further, the second support arm 17 has a wide portion 171 that is formed to be wide on the lower side in a substantially intermediate portion. The wide portion 171 is provided below the straight line connecting at least the rotation shaft 13a of the third roller 13 and the rotation shaft 14a of the fourth roller 14, and has a fixed hook portion 172 for connecting a tension device 20 described later. Have.

  The fourth roller 14 has a rotation shaft 14 a and is provided at the other end of the second support arm 17, and can move along with the rotation of the second support arm 17 like the second roller 12. It rotates at the tip of the support arm 17.

  In the above configuration, as shown in FIG. 1, the yarn L <b> 2 conveyed from above is rotated from the left side of the fourth roller 14 to the lower side and hung to the right side, and from the left side of the third roller 13 to the upper side. Therefore, the fourth roller 14 can apply a downward tension to the yarn L2 in the same manner as the yarn L1.

  In the roller group 10, a long connecting member 16 that connects the second roller 12 and the fourth roller 14 is provided. The connecting member 16 is configured such that a portion connected to the second roller 12 and the fourth roller 14 is rotatable. Accordingly, since the second roller 12 and the fourth roller 14 operate integrally by the connecting member 16, the tensile force T by the first spring member 21 and the tensile force T by the second spring member 22 of the tension device 20 described later. The resultant force 2T can be applied to the entire roller group 10, and an equal tension can be applied to the yarns L1 and L2.

  As shown in FIGS. 3 and 4, the tension device 20 includes a first spring member 21 and a second spring member 22 in parallel, and the second support arm 17 described above, a rotating member 30 and a base 41 described later. Connect. In this embodiment, the first spring member 21 and the second spring member 22 have the same properties as elastic members.

  As shown in FIG. 4, one of the first spring members 21 is connected to the fixed hook portion 172 of the second support arm 17, and the other is connected to the first hook portion 311 of the rotating member 30. As will be described later, since the position of the first hook portion 311 is displaced by being provided on the rotating member 30, the distance between the fixed hook portion 172 and the first hook portion 311 changes. Along with this, since the tensile force of the first spring member 21 changes, the tensile force of the first spring member 21 is variable.

On the other hand, one end of the second spring member 22 is connected to the fixed hook portion 172, and the other end is connected to a second hook portion 41c fixed to a base portion 41 described later. Since the position of the second hook portion 41c is unchanged because it is provided on the base 41 fixed to a support member (not shown), the tensile force of the second spring member 22 is not changed. Here, the second spring member 22 is provided in a state where it is extended by a predetermined amount and has a predetermined tensile force T.

  As shown in FIG. 5A, the rotating member 30 is supported by a base portion 41 fixed to a support member (not shown), and is fixed to the link member 31 and a link member 31. The rotating lever 32 is provided, and is rotatable about the rotating shaft 31a in the direction of the arrow shown in FIG. 3 and FIG. 5 (a).

  One end of the link member 31 is connected to the rotation shaft 31a. Moreover, the link member 31 has the 1st hook part 311 in the substantially intermediate part. The first hook portion 311 is connected to the first spring member 21 as described above.

  The rotation lever 32 is a bar member that is fixed so as to be substantially orthogonal to the other end side of the link member 31 and extends in the rotating planar direction.

  In the above configuration, since the first spring member 21 is connected, the entire rotating member 30 can receive a tensile force in the clockwise direction. Therefore, for example, the position of the first hook portion 311 can be displaced by rotating the rotating member 30 counterclockwise against the tensile force of the first spring member 21 by a human hand or the like. The expansion and contraction of the first spring member 21 connected to the one hook portion 311 can be changed, and the first spring member 21 can hold the tensile force. On the other hand, if the hand which rotated the rotation member 30 is released | separated, it will rotate clockwise by the tensile force which the 1st spring member 21 hold | maintains.

  In addition, when the fixed hook part 172 and the 1st hook part 311 adjoin the predetermined distance or more, it comprises so that the 1st spring member 21 may be in the state which does not have a tensile force. For example, the first spring member 21 having a natural length longer than the predetermined interval is used.

  As shown in FIG. 5A, the rotation restricting device 40 is supported by the base 41 and adjacent to the rotating member 30, as with the rotating member 30. The rotation restricting device 40 includes a cylinder part 42, a locking member 43, and a control part 45.

  The cylinder portion 42 is supported by a cylinder base portion 41 a provided at an end portion of the base portion 41, and is provided at a distance from the base portion 41. Moreover, the cylinder part 42 has the extrusion rod 421 in the base 41 side as shown in FIG.5 (b), and the extrusion rod 421 is shown in FIG.5 (b) based on the signal from the control part 45 mentioned later. Project leftward. The direction in which the push rod 421 protrudes is a direction orthogonal to the rotation direction of the rotation lever 32 of the rotation member 30.

  The locking member 43 is abutted on the push rod 421, has a swinging portion 431 provided in the vicinity of the rotation track of the rotation lever 32, has a predetermined height, and protrudes in the rotation track of the rotation lever 32. And a swinging member base 41b that is fixed to the base 41, has a swinging shaft 433, and supports the swinging member 431 so as to be swingable in a direction orthogonal to the rotation trajectory of the rotary lever 32. Accordingly, the swinging member 431 swings leftward in FIG. 5B, so that the convex portion 432 can be removed from the rotating track of the rotating lever 32. The predetermined height of the convex portion 432 is such that the swinging member 431 swings away from the rotation trajectory of the rotating lever 32.

  As shown in FIG. 6, the control unit 45 controls the operation of the cylinder unit 42 based on a signal from an abnormality detection sensor 91 described later. Specifically, the control unit 45 controls the cylinder unit 42 to project the push rod 421 in the left direction in FIG. 5B in accordance with a signal from the abnormality detection sensor 91.

  According to this rotation restricting device 40, the cylinder portion 42 protrudes the push rod 421, whereby the swing member 431 swings, and the convex portion 432 can be removed from the rotation track of the rotation lever 32. In this embodiment, the rotation restricting device 40 is in a position where the rotation of the rotary lever 32 is restricted at the position where the first spring member 21 holds the same tensile force as the tensile force T held by the second spring member 22. Provided.

  Therefore, in the rotating member 30 and the rotation restricting device 40 described above, only the first spring member 21 can be extended by rotating the rotating lever 32 counterclockwise as shown in FIG. Therefore, the first spring member 21 can hold the tensile force T. Further, the convex portion 432 of the rotation restricting device 40 can restrict the rotation of the rotation lever 32 by closing the rotation orbit of the rotation lever 32 and maintain the tensile force T held by the first spring member 21. . On the other hand, the tensile force T held by the first spring member 21 can be lost by releasing the restriction of the rotation of the rotation lever 32 by the convex portion 432 of the rotation restriction device 40. As described above, since the tensile force is lost not by digital control but by a mechanical configuration, the cost can be reduced.

  As shown in FIG. 3, the tensile force adjusting unit 80 is provided in the vicinity of the rotating member 30. The tensile force adjusting unit 80 makes it possible to change the distance between the first hook portion 311 and the second hook portion 41c to which the first spring member 21 and the second spring member 22 are connected and the other fixed hook portion 172. . By changing these distances, the tensile force of the first spring member 21 and the second spring member 22 can be arbitrarily adjusted. It is possible to retain force.

  The abnormality detection sensor 91 detects an abnormality of the yarns L1 and L2 being conveyed. As shown in FIG. 6, for example, when the yarn L2 is cut during conveyance, the abnormality detection sensor 91 detects that the yarn L2 is cut, and notifies the control unit 45 of the rotation regulating device 40 to that effect. Output a signal. The control unit 45 outputs a signal to the cylinder unit 42 in response to the received signal, and outputs a signal for causing the push rod 421 to protrude.

  Next, the operation of the tension applying device 1 will be described. As shown in FIG. 1, the tension applying device 1 rotates the rotating member 30 counterclockwise so that the first spring member 21 of the tensioning device 20 has a tensile force T. The rotation lever 32 in the rotated rotation member 30 is locked by the convex portion 432 of the rotation restriction device 40 to restrict the rotation of the rotation lever 32. Accordingly, the first spring member 21 connected to the rotating member 30 is maintained in a state having a tensile force T. At this time, since the tension device 20 has a tension force 2T by the first spring member 21 and the second spring member 22, the entire roller group 10 is counterclockwise and the rotation member 30 is clockwise. The moment is applied.

  Thus, the yarn L1 wound around the first roller 11 and the second roller 12 and conveyed, and the yarn L2 wound around the third roller 13 and the fourth roller 14 and conveyed, The tension based on the tensile force 2T by the two of the first spring member 21 and the second spring member 22 of the tension device 20 is evenly distributed and applied.

  From the above, in order to apply the tensile force based on the first spring member 21 and the second spring member 22 arranged in parallel to the two to the entire roller group 10, the equal tension is applied to the yarns L1 and L2. Can do.

  Further, when the two yarns L1 and L2 are being conveyed, for example, when the yarn L2 is cut, the abnormality detection sensor 91 detects that the yarn L2 has been cut. The abnormality detection sensor 91 outputs a signal to that effect to the control unit 45 of the rotation restricting device 40. Receiving the signal, the control unit 45 outputs a signal indicating that the push rod 421 protrudes from the cylinder unit 42. In response to the signal, the cylinder portion 42 causes the push-out portion rod 421 to protrude, whereby the swing member 431 is swung in the left direction in FIG. By this swinging, the convex portion 432 provided on the swinging member 431 deviates from the rotating track of the rotating lever 32, and the restriction on the rotation of the rotating lever 32 is released. As a result, as shown in FIG. 7, the first spring member 21 rotates the rotating member 30, and the first spring member 21 becomes a natural length. Then, the tensile force T held by the first spring member 21 does not act on the roller group 10, and only the tensile force T of the second spring member 22 acts on the entire roller group 10.

  Therefore, a tension based only on the tensile force T of the second spring member 22 can be applied to the remaining unthreaded yarn L1 via the roller group 10. That is, when an abnormality such as one of the yarns breaking occurs, the tensile force T of at least one of the two first spring members 21 and 22 arranged in parallel is set. In order to lose, the tension | tensile_strength which acts on the roller group 10 is also lost, and the tension | tensile_strength with respect to the remaining yarn can be made constant.

  As described above, since it is possible to continue to apply equal tension to each yarn in both normal and abnormal conditions, the two yarns L1 and L2 can be stably wound.

(Second Embodiment)
Next, another embodiment of the winding device according to the present invention will be described. In the following description, components similar to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The winding device in this embodiment includes a tension applying device 101 that applies tension when winding the two yarns L3 and L4 individually. As shown in FIG. 8, the tension applying device 101 has a rod-like fixed support arm 102 extending in a substantially horizontal direction, a rotation transmission box 103 provided substantially below the fixed support arm 102, and the fixed support arm 102. And a rotation support arm 104 that rotates in the proximity and separation direction, a roller group 110 that includes a plurality of rollers provided on the fixed support arm 102 and the rotation support arm 104, and the rotation of the rotation support arm 104. A rotating link member 105 that rotates, a tension device 120 that applies a tensile force to the roller group 110 via the rotating link member 105, and an abnormality detection sensor 92 that detects an abnormality in the yarns L3 and L4. . The two yarns L3 and L4 are conveyed in the directions of the arrows shown in the vicinity of each in FIG. 8, and then individually wound around the bobbin 70 in FIG. 2 provided below the tension applying device 101. Taken.

  The fixed support arm 102 is fixed to a fixed portion in a winding device (not shown) so as to extend in a substantially horizontal direction, and functions as a base for holding each component described below. Further, the fixed support arm 102 has vertical surfaces on the front side and the back side, and a front surface of these is a roller fixing plate 102a for fixing a plurality of rollers to be described later. Is provided.

  The rotation transmission box 103 is fixed to the lower side of the fixed support arm 102 by a holding member 102 b provided on the lower side of the fixed support arm 102. Further, the rotation transmission box 103 has a rotation shaft 103a penetrating from the front to the back. The rotary shaft 103a is configured to be rotatable in the axial direction, and the rotation support arm 104 is fixed at the front-side protruding portion, and the rotation link member 105 is fixed at the rear-side protruding portion. Accordingly, the rotation transmission box 103 interlocks the rotation of the rotation support arm 104 and the rotation link member 105 via the rotation shaft 103a.

  Further, as shown in FIG. 9, the rotation transmission box 103 includes a tension device fixing plate 125 for holding the tension device 120 on the back side in the vertical direction. Accordingly, the tension device 120 can be fixedly held by the tension device fixing plate 125.

  As shown in FIG. 8, the rotation support arm 104 is a substantially rod-like member, and can be rotated in the proximity and separation direction with respect to the fixed support arm 102 by being fixed to the rotation shaft 103a. The rotation support arm 104 has a vertical surface 104a on the front side, and the vertical surface 104a forms a substantially same plane as the roller fixing plate 102a of the fixed support arm 102 as shown in FIG. ing. Accordingly, the plurality of rollers provided on the fixed support arm 102 and the rotation support arm 104 rotate in substantially the same plane.

  As shown in FIG. 8, the roller group 110 includes a fixed roller group 110 a (first roller 111 to third roller 113) supported by the fixed support arm 102 and a moving roller group supported by the rotation support arm 104. 110b (fourth roller 114 and fifth roller 115). Since the rollers 111 to 115 rotate on substantially the same plane as described above, the rollers 111 can be wound and conveyed. The sixth roller 116 provided on the fixed support arm 102 is a roller for conveying only the yarn L4 to the bobbin 70, and the seventh roller 117 is a roller for conveying only the yarn L3 to the bobbin 70.

  The first roller 111 to the third roller 113 are arranged substantially linearly on the roller fixing plate 102a of the fixed support arm 102, and each of the first roller 111 to the third roller 113 is provided with two rollers in parallel to convey the two yarns L3 and L4. .

  On the other hand, the fourth roller 114 and the fifth roller 115 are arranged substantially linearly on the vertical surface 104 a of the rotation support arm 104. Therefore, the fourth roller 114 and the fifth roller 115 rotate in the approaching and separating directions with respect to the first roller 111 to the third roller 113 provided on the fixed support arm 102 by the rotation of the rotation support arm 104. The fourth roller 114 and the fifth roller 115 also include two rollers in parallel for conveying the two yarns L3 and L4 in the same manner as the first roller 111 to the third roller 113.

  In this roller group 110, the yarns L3 and L4 are wound in the order of the first roller 111, the fourth roller 114, the second roller 112, the fifth roller 115, and the third roller 113, and only the yarn L4 is the sixth. Via the roller 116, it is conveyed to the next step (winding with the bobbin 70). Further, only the yarn L3 is conveyed to the next step through the seventh roller 117 in the same manner as the yarn L3. As described above, by winding the yarns L3 and L4 around the plurality of rollers, tension can be applied when the yarns L3 and L4 are conveyed. Further, since the yarns L3 and L4 are conveyed by the first roller 111 to the fifth roller 115 through the yarn path having substantially the same environment, it is possible to apply an equal tension to the yarns L3 and L4.

  As shown in FIG. 10, the rotation link member 105 is a plate member fixed to a rotation shaft 103a protruding from the back side of the rotation transmission box 103. As described above, the rotation link member 105 is interposed via the rotation shaft 103a. Rotating integrally with the rotation of the rotation support arm 104. The rotation link member 105 has a connecting portion 105a that connects the pulling device 120 to a position separated by a predetermined distance D from the rotating shaft 103a. Further, a straight line m1 (a dashed line in FIG. 10) connecting the rotary shaft 103a and the connecting portion 105a, and a straight line m2 (a dashed line in FIG. 10) drawn from the rotary shaft 103a in the direction in which the rotation support arm 104 extends. Is configured so that the included angle θ is 90 degrees <θ <180 degrees. By doing so, a tensile force of a tension device 120 described later can be efficiently applied as a moment. Here, the rotation shaft 103a, the rotation support arm 104, the rotation link member 105, and the rotation transmission box 103 that rotate them integrally function as a rotation mechanism.

  As shown in FIG. 9, the tension device 120 includes a first air cylinder 121 and a second air cylinder 122 in parallel. These air cylinders 121 and 122 have one end connected to the connecting portion 105a of the rotation link member 105 and the other end connected to the connecting portion 125a of the tension device fixing plate 125. The air cylinders 121 and 122 are configured to be rotatable. Here, the connecting portion 125a is fixed to the fixed support arm 102 via the tension device fixing plate 125 and the rotation transmission box 103, and the connecting portion 105a is rotated via the rotating link member 105 and the rotating shaft 103a. The moving support arm 104 is fixed. Since the first air cylinder 121 and the second air cylinder 122 are connected in this way, the tension device 120 includes the fixed support arm 102 and the rotation support arm 104 provided with the first roller 111 to the fifth roller 115. It is possible to apply a tensile force to. The first air cylinder 121 and the second air cylinder 122 are separately supplied with air by an air supply device 130, which will be described later, and each of them holds a tensile force T (total tensile force 2T). Is configured to do.

  Since the first air cylinder 121 and the second air cylinder 122 hold the tensile force 2T by the air supply device 130 and pull the connecting portion 105a of the rotating link member 105 by the held tensile force 2T, in FIG. The rotation link member 105 rotates in the clockwise direction indicated by the arrow. As described above, the tension device 120 applies the tensile force 2T to the rotation support arm 104 that is integral with the rotation link member 105.

  Further, when the supply of air is stopped by the air supply device 130, the first air cylinder 121 and the second air cylinder 122 lose the corresponding tensile force. For example, when the supply of air to the first air cylinder 121 is stopped, only the tensile force T of the second air cylinder 122 to which air is continuously supplied is applied to the rotation support arm 104. In other words, the tensile force can be easily applied by supplying air to the air cylinders 121 and 122, and the tensile force can be reduced by stopping the supply of air to the air cylinders 121 and 122. Can be easily lost.

  In addition, since both the air cylinders 121 and 122 in the tension device 120 are provided in parallel, they are concentrated on one side (the back side in this embodiment) of the tension applying device 101. It can be installed inside the base, and the winding device can be downsized.

  Here, in the air supply device 130 described above, whether or not air is supplied to the air cylinders 121 and 122 of the tension device 120 is controlled by the control device 140. As shown in FIG. 11, the control device 140 receives a signal about the abnormality of the yarns L3 and L4 transmitted from the abnormality detection sensor 92. Based on the received signal, control device 140 transmits a signal as to whether air supply device 130 is to supply air to first air cylinder 121 and second air cylinder 122 or not. The air supply device 130 supplies and stops air to the first air cylinder 121 and the second air cylinder 122 based on the received signal. Here, the abnormality detection sensor 92 has the same configuration as the abnormality detection sensor 91 in the first embodiment, except that a signal regarding abnormality of the yarns L3 and L4 is transmitted to the control device 140.

  Next, the operation of the tension applying device 101 will be described. As shown in FIG. 8, the tension applying device 101 applies a desired tension to the yarns L3 and L4 that are wound and conveyed. Specifically, by supplying air to the first air cylinder 121 and the second air cylinder 122 by the air supply device 130, the tension device 120 holds the tensile force 2T, and via the rotation link member 105 and the rotation shaft 103a. Thus, the rotation support arm 104 is configured to be rotated in the separating direction of the fixed support arm 102, and the yarns L3 and L4 are conveyed. By doing so, since the tensile force 2T based on the first air cylinder 121 and the second air cylinder 122 of the tension device 120 is applied to the roller group 110, it is wound around the first roller 111 to the fifth roller 115 and conveyed. A uniform tension can be applied to the yarns L3 and L4.

  Further, when the two yarns L3 and L4 are being conveyed, for example, when the yarn L3 is cut, the abnormality detection sensor 92 detects that the yarn L3 has been cut. The abnormality detection sensor 92 transmits a signal to that effect to the control device 140. The control device 140 that has received the signal transmits a signal to the air supply device 130 to stop the supply of air to the first air cylinder 121. In response to this signal, the supply of air to the first air cylinder 121 is stopped, so that the tensile force T for the first air cylinder 121 is lost from the tensile force 2T held by the tension device 120. . Accordingly, the tension force of the tension device 120 becomes the tension force T of only the second air cylinder 122, and only the tension force T of the second air cylinder 122 acts on the roller group 110.

  As described above, a tension based only on the tensile force T of the second air cylinder 122 can be applied to the yarn L4 remaining without being cut through the roller group 110. Therefore, when an abnormality such as the breakage of one of the yarns occurs, the tensile force T of at least one of the two first air cylinders 121 and the second air cylinders 122 arranged in parallel is set. In order to make it lose, the tensile force which acts on the roller group 110 is also lost, and the tension with respect to the remaining yarn can be made constant.

  As described above, since it is possible to continue to apply an equal tension to each yarn in both normal and abnormal conditions, the two yarns L3 and L4 can be stably wound.

  In the above embodiment, the case where an air cylinder using air pressure is used as the tension member has been described. However, the present invention is not limited to this, and a hydraulic cylinder using oil pressure may be used.

  Moreover, although the case where two yarns are wound up was demonstrated, it is not restricted to this, Three or more may be sufficient. At this time, the number of spring members or air cylinders is increased in accordance with the number of yarns to be wound.

  Moreover, although the case where the tensile force of at least one of the plurality of spring members or the air cylinder or the tensile force of the air cylinder is lost has been described, the present invention is not limited to this, and the tensile force corresponding to the necessity is required. May be reduced.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.
