Description

  The present invention relates to a yarn traverse device and a method of manufacturing a yarn package manufactured using the traverse device.

  Conventionally, it has a yarn path regulation guide for guiding this kind of yarn, and is arranged on the upper and lower sides of the upstream side and downstream side, and delivers the yarn between the blades rotating in opposite directions, along the yarn path regulation guide. A traverse device for a yarn that traverses a predetermined stroke yarn has a configuration as shown in FIG. 14 (see, for example, Patent Document 1).

  In FIG. 14, the first traverse element 1 has a first blade 1a that rotates counterclockwise and a second blade 1b that rotates clockwise, each of which has two rotation shafts that rotate concentrically in opposite directions. Installed on.

  The second traverse element 2 has a third blade 2a that rotates counterclockwise and a fourth blade 2b that rotates clockwise, each of which is attached to two rotating shafts that rotate concentrically in opposite directions. . The third traverse element 3 has a fifth blade 3a that rotates counterclockwise and a sixth blade 3b that rotates clockwise, each of which is attached to two rotating shafts that rotate concentrically in opposite directions. Yes.

  These three traverse elements 1, 2, and 3 are arranged in a positional relationship in which the rotation trajectories of the tips of the blades of adjacent traverse elements intersect each other. On the other hand, a yarn path regulation guide 5 for regulating the position of the yarn Y in the vertical direction in FIG. 14 is attached.

  The traveling yarn Y (not shown) is moved from the left end to the right end of the traverse by the first blade 1a, the third blade 2a, and the fifth blade 3a while being position-regulated by the yarn path regulating guide 5. The 6 blades 3b, the 4th blade 2b, and the 2nd blade 1b are moved from the right end to the left end. By these continuous actions, the yarn Y traveling through the traverse fulcrum (not shown) is traversed along the yarn path regulating guide 5 in the left-right direction in FIG. It is traversed and wound up as a package on a bobbin by a yarn winding device (not shown) located downstream of the traverse device in the running direction of the yarn Y.

  At the traverse end, the yarn is sandwiched between the end of the first blade 1a and the end of the second blade 1b, or between the end of the fifth blade 3a and the end of the sixth blade 3b. The thread is transferred between these blades, and the traverse direction is reversed.

  In this traverse device, at the time of delivery of the yarn at the end portion, on the one hand, the blade 1b located on the upstream side with respect to the yarn traveling direction is sent to the end portion and the blade 1a located on the downstream side (hereinafter, located on the upstream side). A configuration in which the blade is received by the upstream blade and the blade located downstream is received by the downstream blade) and sent to the central portion, and the other blade is sent by the downstream blade 3a to the end portion and is received by the upstream blade 3b and sent to the central portion. Thus, the vertical relationship of the blades in the thread delivery is different on the left and right.

  In the above configuration, when the downstream blade 3a is fed to the end portion and received by the upstream blade 3b, the timing at which the yarn is detached from the downstream blade is used to catch the yarn and transmit the driving force to the blade. When a delay occurs due to a gear back-crash or the like, as shown in FIG. 15 (A) (in the figure, the arrow indicates the traveling direction of the blade), the thread is more tightly sandwiched between the delivery blades, Rub and fluff and sagging occur. As the tension further increases, as shown in FIG. 15B, the vibration (yarn sway) that occurs when the yarn comes off from the downstream blade increases. Since this force is not interrupted until the package, it is directly transmitted to the package, and a phenomenon that the yarn is detached from the wound yarn layer at the end of the package, that is, yarn dropping occurs.

  On the other hand, when the upstream blade 1b sends to the end portion and receives by the downstream blade 1a, the downstream blade to be received is between the package even if the upstream blade release timing is delayed. When the delivery is performed at the same timing, there is a difference in the package quality between the left and the right.

  And a yarn guide for forming a traverse locus, wherein a difference is provided in the distance from the traverse center of the rotating blade (blade) to the left and right yarn guide surfaces at a yarn turning point on the yarn guide, In addition to the guide, there is provided an auxiliary guide for assisting the delivery of the yarn at the turning point of the traverse locus, and a traverse device in which the auxiliary guide and the yarn guide are arranged so as to sandwich the upper and lower sides of the two rotary blades. It is disclosed (for example, see Patent Document 2).

The main purpose of this traverse device is to reduce the bending of the right and left ends of the yarn in the front-rear direction, to suppress damage to the yarn, and to make the left and right shapes of the package end equal, and from the downstream blade to the yarn When a delay occurs due to catching of the yarn on the blade or backlash of the gear used to transmit the driving force to the blade at the timing of the release of the yarn, the movement of the yarn outside the traverse stroke and the blade The bending of the yarn in the traverse direction by pinching the yarn between them is not taken into consideration, and there is a problem that it is impossible to avoid the occurrence of fluff, sagging and yarn dropping phenomenon. Further, by changing the positions of the left and right turning points from the traverse center, the traverse speeds of the yarns at the left and right end portions are different, and there is a problem that the amount of ear standing of the yarns differs between the left and right. When the amount of ears is different, the end surface with more ears is more in contact with the contact roller, the package hardness is different on the left and right end surfaces, and unraveling defects such as thread breakage are more likely to occur when releasing the thread. There's a problem.

Threads that are controlled and absorb vibrations and vibrations that occur during yarn delivery to suppress propagation to the package, thereby stabilizing the behavior during yarn delivery, and preventing yarn dropping, fluff, and sagging at the package end. Manufacturing of strip packages is possible. Further, at the end face that is sent to the end face by the upstream blade of the traverse device and received by the downstream blade, the yarn removal from the upstream blade is performed by the yarn path regulating guide or auxiliary guide installed further upstream of the upstream blade, By configuring the upper and lower blades so that there is no overlap section where the yarn is sandwiched at the same time, the yarn passing behavior is stabilized at both end faces of the package, and the yarn end, fluff, and slack are less likely to occur at the package end. The package can be manufactured.

  Furthermore, the yarn package manufactured using the present yarn traverse device is a good package that is less likely to cause yarn breakage when the yarn is unwound therefrom.

  FIG. 1 illustrates a yarn winding device according to the present invention, and a machine base 23 is provided with a traverse device 60 and a bobbin holder 25 connected to a rotation driving means. The bobbin holder 25 holds a yarn package composed of a bobbin 27 and a yarn layer 26 formed on the outer periphery thereof. The traverse device 60 includes a touch roller 24 that is rotatable, and the touch roller 24 is in contact with the outer peripheral surface of the yarn layer 26.

  As illustrated in FIG. 2, the traverse device 60 includes a plurality of traverse units 50 and a drive motor 16 in the casing 15. The motor shaft 17 of the drive motor 16 is connected to the gear 11 of each traverse unit 50 via the rotation transmission means. For example, in FIG. 2, the motor shaft 17 is connected to a pulley 18 fixed to the gear 20, and the gear 20 and the gear 11 are engaged with each other, whereby the motor shaft 17 is connected to the gear.

  The traverse unit 50 includes the traverse mechanisms 100, 200, and 300 in parallel in the housing 4, as shown in FIG. 4 as viewed in the direction of arrows XX in FIG. 3 and FIG. Further, shafts 12 and 14 fixed to the housing 4 and gears 11 and 13 rotatably connected to the shafts 12 and 14 are also provided.

  As illustrated in the traverse mechanism 100 of FIG. 3, each traverse mechanism includes a component (rotary component 109) in which the blade 101 is fixed to one end of the outer shaft 103 and the gear 107 is fixed to the other end. A downstream blade 102 is provided at one end of the inner shaft 104, and a component (rotary component 110) having a gear 108 fixed at the other end. The rotating component 109 is installed in the housing 4 through the bearing 105, and the rotating component 110 is installed in the rotating component 109 through the bearing 106. This configuration is the same for the traverse mechanisms 200 and 300.

  In such a traverse unit 50, the gears 107, 207, and 307 of the traverse mechanisms 100, 200, and 300 are meshed in series, and the gears 108, 208, and 308 are also meshed in series. . Further, as shown in FIG. 4, the gear 108 is meshed with the gear 13, and the gear 13 and the gear 307 are meshed with the gear 11.

  Further, as shown in FIG. 5 as viewed in the direction of arrows ZZ in FIG. 3, the traverse unit 50 includes a traverse mechanism 100, 200, and 300 blades arranged in parallel and a direction in which the traverse mechanism is arranged. A yarn path regulating guide 5a, which is parallel to the upstream blades 101, 201, and 301 and has a surface for regulating the yarn toward the center of the rotating blade, is installed.

  In FIG. 5, the upstream side is the upstream side, and the near side is the downstream side.

  As shown in FIG. 6, the yarn path regulation guide may have a configuration in which only 5b in which a regulation surface is arranged from the center of the rotating blade toward the upper (outward) direction may be installed, and the yarn path regulation guides 5a and 5b may be arranged as yarns. However, it is also possible to adopt a configuration in which both of them are arranged at the same time with a certain distance (0.5 mm or more and 5 mm or less) that can smoothly move in the traverse direction. In addition, the yarn path regulation guide preferably has a symmetrical shape about the traverse center so that the speed of guiding the yarn is constant on the left and right and the package shape is uniform on the left and right. It is preferable that the yarn turning position on the guide is also substantially symmetrical with respect to the traverse center.

  The left-right symmetric position mentioned here is a slight position generated due to factors other than the positional relationship between the blade and the yarn path regulation guide, which occurs due to backlash of the gear driving the blade or variations in the thickness of the yarn. This is the range that allows the deviation. In this embodiment, the yarn path regulation guide shape is a corrugated shape, but it may be an arc shape, an arc shape at the center and a straight end surface, and the yarn is guided in the traverse direction without any problem according to the rotating blade configuration. Anything is acceptable.

Further, as shown in FIGS. 5 to 7, the yarn is guided (restricted) toward the tip of the downstream blade as the yarn is fed from the center toward the end surface further downstream of the downstream blade 302 on the left end surface. ) And / or a lower yarn path regulating guide 7 for regulating the yarn removal from the downstream blade 302 and / or the movement of the yarn detached from the downstream blade 302 to the outside of the traverse stroke. By installing the lower yarn path regulation guide 7 on the downstream side of the downstream blade 302, the yarn is supplied to the package (not shown) via the lower yarn path regulation guide 7 and is generated when the blade is delivered. The vibration and the yarn swaying are alleviated by the tension generated by contacting the lower yarn path regulating guide 7, and an effect of forming a good package with no yarn dropping is produced. Further, the lower yarn path regulating guide 7 of this configuration is arranged so that the yarn guided along the yarn path regulating guide 5a or 5b by the downstream blade 302 is fed to the end face, and the yarn is moved in the downstream blade tip direction, that is, the front side. The guide surface of the lower yarn path regulation guide 7 is arranged with respect to the guide surface of the yarn path regulation guide 5a or 5b (if the guide surface shape of the yarn path regulation guide is an arc, the downstream blade The angle α in the direction away from the blade rotation center (so that the yarn is pushed forward) as the yarn is fed to the end face (relative to the tangential direction of the yarn position on the yarn path regulation guide when the yarn is separated from the yarn) The structure which comprises is preferable. If the angle α is too large, the yarn is sandwiched between the downstream blade 302 and the lower yarn path regulation guide 7, and the yarn is damaged. Therefore, the guide surface at the end of the yarn path regulation guide 5a or 5b ( When the shape of the end guide surface of the yarn path regulation guide is an arc, the lower thread path regulation guide 7 is formed with the yarn tangential direction of the yarn position on the yarn path regulation guide when the yarn is separated from the downstream blade. The angle α is preferably in the range of 5 ° to 50 °, more preferably in the range of 5 ° to 30 °. With this configuration, as the yarn is sent to the end, the bending in the front-rear direction by the lower yarn path regulation guide increases and the tension increases, and this tension stabilizes the behavior during yarn delivery and / or It is possible to regulate the movement of the yarn that has come off the blade out of the traverse stroke.
Further, as shown in FIG. 8a, the lower yarn path regulation guide is configured so that the yarn is sent to the end face by the downstream blade and received by the upstream blade, and further downstream of the downstream blade. It may be configured to form a steep angle in a range of 90 ° ± 20 ° with respect to the traverse direction of the yarn and to restrict the movement of the yarn out of the traverse stroke.
By adopting this configuration, the yarn is restricted from moving out of the traverse stroke, and the delay in yarn return is improved. It becomes possible to suppress. The amount of contact between the lower yarn path regulation guide and the yarn is defined by the position where the yarn and the lower yarn path regulation guide start to contact. If the contact amount is too small, the vibration and vibration are not absorbed and the effect of preventing yarn drop is obtained. If the amount is too large, the yarn is severely bent between the blade sent to the end face and the lower yarn path regulation guide, and fluff and sagging occur. Therefore, the contact (start) position with the yarn of the lower yarn path regulation guide of this configuration is the center of the traverse stroke from the position where the upstream blade receives (begins to contact) the yarn sent to the end face by the downstream blade. A range of up to 7 mm is preferable, and a range of up to 4 mm from the position where the upstream blade receives the yarn to the center of the traverse stroke is more preferable.

  Furthermore, as a lower yarn path regulation guide configuration, as shown in 7b of FIG. 9, the yarn guided by the downstream blade is guided in the direction of the tip of the downstream blade, and the yarn from the downstream blade It may have two guide surfaces: a guide surface that assists removal, and (b) a guide surface that regulates the movement of the yarn sent to the end surface by the downstream blade outside the traverse stroke.

With this configuration, it is possible to obtain both effects of yarn removal assistance (reduction of pinching between blades) and suppression of yarn movement outside the stroke, and yarn drop can be greatly reduced. . Further, the optimum configuration of each guide surface of the guide having this configuration is preferably the same as the configuration of the lower yarn path regulation guide shown in FIGS.
That is, the guide surface that guides in the distal direction of the downstream blade as the yarn is fed to the end portion is set to the guide surface at the end portion of the yarn path regulation guide 5a or 5b (the end guide of the yarn path regulation guide When the surface shape is an arc shape, the thread is moved away from the blade rotation center as the yarn is sent to the end face (relative to the tangential direction of the yarn position on the yarn path regulation guide when the yarn is separated from the downstream blade). The lower yarn path regulation guide 7b preferably forms an angle α so that the yarn is pushed out to the side). Specifically, if the angle α is too large, the downstream blade 302 and the lower yarn path regulation guide 7 sandwich the yarn. In order to damage the yarn, the guide surface at the end of the yarn path regulation guide 5a or 5b and the yarn from the downstream blade are separated when the end guide surface shape of the yarn path regulation guide is an arc. Thread guide at the time The angle α formed by the lower yarn path restriction guide 7 and the tangential direction of the yarn position on the restriction guide is preferably in the range of 5 ° to 50 °, more preferably in the range of 5 ° to 30 °. good.
Further, the surface that regulates the movement of the yarn sent to the end surface outside the traverse stroke forms a steep angle in the range of 90 ° ± 20 ° with respect to the traverse direction of the yarn, and is in contact with the yarn ( The start position is preferably in a range from the position where the upstream blade receives (begins to contact) the yarn sent to the end face by the downstream blade to 7 mm toward the traverse stroke center, more preferably the upstream blade. The range from 4 mm to 4 mm from the position to receive the yarn to the center of the traverse stroke is good.
Further, these lower yarn path regulation guides 7, 7a, 7b are more effective as the distance to the downstream blade 302 is closer to some extent, but if they are too close, they contact the downstream blade 302 and damage the downstream blade 302. Therefore, it is preferable that the distance between the downstream blade 302 and the downstream blade is within a range of 0.5 mm to 10 mm, and more preferably a position within a range of 0.5 mm to 5 mm.

  Further, as shown in FIG. 10, the blade rotation is performed so that the end surface shape of the yarn path regulating guide 5c on the upstream side of the upstream blade 101 on the right end surface is guided toward the upstream blade tip as the yarn is fed to the end surface. The yarn is removed from the upstream blade 101 by inclining in a direction away from the center, and the yarn is sent to the end surface by the upstream blade 101, received by the downstream blade 102, and delivered at the end surface to be sent to the central portion. By configuring the timing so that there is no overlap area where the upstream blade and the downstream blade are in contact with and pinched at the same time, there is no pinching of the yarn at both end faces of the package, and thread drop is less likely to occur A device is obtained.

Further, as shown in FIG. 11, the yarn removing action from the upstream blade 101 may be performed using an upper yarn path regulating guide or auxiliary guide 8 provided further upstream of the yarn path regulating guide 5c.
It is preferable that the right end surface of the yarn path regulating guide 5c and the guide surface of the auxiliary guide 8 are configured so that the yarn return position is substantially bilaterally symmetrical about the traverse center. In order to make the package shape uniform on the left and right, it is more preferable that the shape of the lower restriction guide guide surface on the left end surface and the guide surface shape on the right end surface are symmetrical with respect to the traverse center.

  By using such an apparatus, the rotation of the drive motor 16 is transmitted to the gear 11 via the motor shaft 17 in FIG. In FIG. 4, the rotation of the gear 11 is transmitted to the gear 108 via the gear 13 and also to the gear 307. Further, in FIG. 3, the rotation transmitted to the gear 108 and the gear 307 is transmitted in the order of the gear 108 to the gear 208 and the gear 308, and from the gear 307 to the gears 207 and 107. By transmission of these rotations, the gears of each traverse mechanism rotate synchronously, and each blade integrated with each gear via the outer shaft or the inner shaft also rotates synchronously. The blades 101, 202, and 301 shown in FIGS. 5 and 6 rotate clockwise, and the blades 102, 201, and 302 rotate counterclockwise. Therefore, the yarn Y is continuously delivered by the blades 302, 301, 202, 101, 102, 201, 302,... While sliding on the yarn path regulating guide 5a and / or 5b. By repeating this, the yarn Y is traversed left and right.

  In the yarn delivery, the yarn sent to the end surface along the yarn path regulation guide by the blade 302 is sent to the end surface by the downstream blade 302 and sent to the center by the upstream flow blade 301. The thread that has been guided by the regulation guide 7 in the direction of the blade tip and is detached from the blade 302 at the end and tries to move outward by its own inertial force is pushed forward by the lower yarn path regulation guide 7. After being held on the lower yarn path regulation guide 7 by the tension generated by this, it is immediately delivered to the blade 301 and sent to the center.

At this time, as shown in FIG. 12, the phase difference around the rotation axis of the blade from the yarn receiving position of the upstream blade 301 to the yarn contact surface when the yarn is released from the blade 302 is within 5 °. More preferably, a configuration in which the yarn is delivered to the blade 301 with almost no time difference immediately after the yarn is detached from the blade 302 is preferable.
With the above configuration, the yarn Y can be smoothly transferred without being bent by the downstream blade 302 and the upstream blade 301 as shown in FIG.

  In the yarn winding device shown in FIG. 1, the yarn Y thus traversed is pressed against the touch roller 24 with a predetermined surface pressure on the bobbin 27 held by the rotating bobbin holder. Layer 26 is formed and wound up as a yarn package.

  In the manufacture of the above yarn package, if the tension when the yarn is wound around the bobbin 27 and the winding tension are too high, the yarn moves to the center with its own tension immediately after the yarn comes off from the blade, and between the blades. A problem that prevents proper delivery occurs and traverse becomes unstable. In addition, when the tension is too low, problems such as inability to transfer the yarn between the blades occur, and therefore the tension is preferably in the range of 0.5 g to 30 g.
