Description

Wing Traverse Device {TRAVERSE DEVICE HAVING ROTATING WINGS}

TECHNICAL FIELD The present invention relates to a vane traverse device which reversely rotates two yarn guide vanes, and more particularly, to a vane traverse device used when winding a yarn as a conical package.

The wing traverse device reversely rotates two superimposed thread guide vanes at a constant speed to transfer the yarns wound in the package to their thread guide vanes alternately, and at the same time, the thread guide plates arranged along the interlocking trajectory of the thread guide vanes. By guiding, the yarn wound around the package is reciprocated in the axial direction.

As an improvement of this kind of traverse apparatus, the wing traverse apparatus of Unexamined-Japanese-Patent No. 2560918 is known. This wing traverse device differs from each other in the number of two threaded guide blades which are overlapped up and down, and at the same time by varying their rotational speed by the inverse of the number ratio, the traverse speeds of the return and return paths, In other words, the number of winds of the road and the return home is different.

By the way, in such a wing traverse apparatus, although the thread guide vanes which traverse a thread substantially differ in the rotational direction of upper and lower wings, since each wing | blade rotates at a constant speed, a traverse speed is a right end part and a left end part of a package. It was constant in. Therefore, even if it is going to form a cone shaped package using the said blade traverse apparatus, it is difficult to obtain the suitable package of a good shape.

That is, in the case of forming a conical package, on the small-diameter side, the traverse speed should be increased to reduce the thread winding amount, and on the large-diameter side, the traverse speed should be slowed to increase the thread winding amount. Since the traverse speed does not change on the large diameter side and the small diameter side of the package, it is difficult to obtain a conical package.

SUMMARY OF THE INVENTION An object of the present invention in view of the above circumstances is to provide a vane traverse device capable of obtaining an appropriate conical package having excellent shape.

① The wing traverse device according to the present invention, which is designed to achieve the above object, includes two thread guide vanes which are reversely rotated with each other, an elliptic driven gear installed at an input portion of the thread guide vane, and a driving motor meshed with the driven gear. An elliptical cylindrical gear provided at the output of the ellipsoidal device, the pulsating rotation of the thread guide vane causes the traverse speed to be changed in the axial direction of the conical package, and the traverse speed is fast on the small diameter side of the package. On the side, the gear is set to be slow.

According to the present invention, by using the elliptical-shaped driving gear and the driven gear to pulsate the seal guide blades to change the traverse speed in the axial direction of the conical-shaped package, and at the same time the traverse speed is increased Since the package is set to be small on the small diameter side and slow on the large diameter side, the winding amount of the seal is small on the small diameter side of the package and increases on the large diameter side, so that an appropriate conical package having excellent shape can be obtained.

(2) In addition, the gearing is located on a path where the minimum traverse speed by the thread guide vanes is directed from the large diameter side to the small diameter side of the conical package, and the maximum traverse speed is located on the path from the small diameter side to the large diameter side. It may be set to do so.

In this case, since the average of the traverse speeds of the path from the large diameter side to the small diameter side of the package is slower than the average of the traverse speeds of the path from the small diameter side to the large diameter side, the actual length wound in the path from the large diameter side to the small diameter side is smaller diameter side. Is longer than the yarn length wound on the path from the large diameter side to the large diameter side, and the number of windings of the path from the large diameter side to the small diameter side is larger than the number of windings of the path from the small diameter side to the large diameter side. As a result, the reelability of the yarn is improved.

This point will be described in more detail with reference to FIGS. 6A, 6B, 7A, and 7B.

In general, if the number of windings (coil number) is too large at the time of winding, compression of the inside of the package proceeds as the wound diameter increases, and as shown in FIG. 6A, the inner seal layer collapses, thereby expanding the bulge package at both ends of the package. (bulge-package). In order to prevent this, the number of windings for obtaining an appropriate package having the shape shown in FIG. 6B is empirically determined by the yarn count and the material of the yarn.

7A and 7B illustrate the number of winds from the viewpoint of ease of loosening. Shown in FIG. 7A is a package with a small number of windings, and the curvature R of the yarn is small at the thread release point at which the yarn is separated from the package surface. On the other hand, shown in FIG. 7B is a package with a large number of windings, and the curvature R is large at the thread release point.

When comparing these, since the thing of FIG. 7A whose curvature R is small has a favorable thread | separation from a package surface, the rise of a thread release balloon is excellent, there is little frictional contact with the thread wound below, and the lower thread | movement moves It's hard to win. 7B having a large curvature R has a lot of frictional contact with the thread wound below, so that not only the rise of the thread release balloon is poor, but also the yarn loosened due to the friction with the package surface is rotated and the fluff of the lower layer yarn is Since the back is rolled up, the lower thread moves in the thread unwinding direction.

The lower thread thus moved is not only a tapered cone wound package, but also a large number of winds, so that the coil is likely to loosen due to the small traverse angle, and it is also easy to generate entangled pieces with the loose thread. Here, if the angle θ shown in Fig. 7B is made as large as possible, the curvature R becomes small, so that the loosening property of the yarn is improved. The angle θ can be increased by adjusting the number of winds, but as described above, the number of winds is limited in order to obtain an appropriate package.

When the thread unwinding point moves from the large diameter side to the small diameter side, that is, the thread unwinding point moves in the same direction as the thread dispensing direction, the smaller the number of winds is, the larger the angle θ becomes and the thread unwinding point is smaller than the thread unwinding direction. When moving from the side to the large diameter side, the larger the number of winds, the larger the angle θ. Therefore, in winding, the number of the winds of the path | route from the large diameter side to the small diameter side was made more excellent than the number of the winds of the path | route from the small diameter side to the large diameter side, and it is excellent in thread loosening property.

Considering the above invention in view of the above circumstances, according to the above invention, the shape of the package is appropriately maintained by changing the ratio of the number of windings back and forth without changing the total number of round trip winds. The winding which improved the loosening property of a thread can be realized.

(3) In addition, the above-described vane traverse device includes a sensor for detecting the rotational speed of the package, and a control unit for adjusting the rotational speed of the drive motor according to the output of the sensor, wherein the control unit rotates the package and seals the guide blades. The relationship with the rotation of may be maintained regardless of the rotational speed of the package.

In this case, in the case of contact rotation driving of the package by the friction drum, even if there is a slip between the friction drum and the package at the start of rotation after the thread joint, the sensor and the control unit rotate the package and guide the seal. Since the relationship with the rotation of the blades is maintained, a suitable package without disturbed traverse can be formed.

EMBODIMENT OF THE INVENTION Hereinafter, one Embodiment of this invention is described based on an accompanying drawing.

BRIEF DESCRIPTION OF THE DRAWINGS It is a schematic diagram which shows using the blade traverse apparatus which concerns on a present Example as a traverse mechanism of an automatic winder.

The automatic winder rewinds the yarn 1 released from the thread supply bobbin (not shown) to the conical package 2 while cutting off the defective portion of the yarn 1. The conical shaped package 2 is supported such that the left and right ends of the bobbin 3 can freely rotate by the bobbin holder 4, and are driven in contact rotation by the friction drum 5. Both ends of the friction drum 5 are supported by the bearing 6, and are rotationally driven by the winding motor 7, the belt 8, and the like. In the vicinity of the friction drum 5, the blade traverse apparatus 9 for traversing the yarn 1 wound by the package 2 is arrange | positioned.

The wing traverse apparatus 9 is formed by two thread guide vanes 10a and 10b which are reversely rotated by each other by a gear mechanism (not shown) and a mountain shape along the movement trajectory of the thread guide vanes 10a and 10b. The thread guide plate 12 which has the 11 is provided, and the thread 1 which turns to the package 2 from the thread supply bobbin which is not shown in figure is alternately transmitted to the said thread guide vane 10a, 10b, and is It guides with the guide part 11 of the guide plate 12, and transversely moves. The thread guide vanes 10a and 10b have their rotation shafts 13a and 13b slightly displaced, and are reversely rotated at the same speed by a known gear mechanism (not shown).

An elliptical driven gear 14 is provided at the input of the gear mechanism of the thread guide vanes 10a and 10b so as to eccentrically rotate the rotation shaft 15 thereof. An elliptical motive gear 16 is engaged with the driven gear 14 by eccentrically rotating the shaft 17. The elliptical shapes of these driven and motive gears 14 and 16 are respectively molded so that they are always engaged. The prime mover 16 is rotationally driven by the drive motor 21 via a power transmission mechanism 20 composed of a pulley 18, a belt 19, and the like. In addition, the power transmission mechanism 20 may be a sprocket, a chain, a gear train, or the like.

According to this configuration, when the drive motor 21 is rotated at a constant speed, the driven gear 14 is pulsated to rotate through the motive gear 16. Here, pulsation rotation means that the angular velocity fluctuates during the rotation of the driven gear 14 by one rotation. More specifically, the angular velocity of the driven gear 14 is maximum when the long diameter portion 16a of the driven gear 16 is engaged with the short diameter portion 14b of the driven gear 14 as shown in FIG. 1. On the contrary, when the short diameter part 16b of the prime gear 16 engages with the long diameter part 14a of the driven gear 14, it becomes minimum.

When the driven gear 14 pulsates in this way, the thread guide vanes 10a and 10b pulsate rotation at the same speed in the opposite direction to each other, so that the traverse speed of the seal 1 varies in the axial direction of the package 2. do. In detail, one reciprocating traverse in which the seal 1 reaches the large diameter side end 2b from the small diameter side end 2a of the package 2 and then returns to the small diameter side end 2a is driven by the driven gear 14. The gear ratio is set so as to correspond to one rotation of), and the maximum traverse speed and the minimum traverse speed are generated once during the one round trip traverse of the seal 1.

More specifically, in this embodiment, when the seal 1 is located at the small-diameter side end 2a of the package 2, as shown in Fig. 2, the long diameter portion 16a of the motive gear 16 The shorter diameter of the prime mover 16 is engaged when the traverse speed is maximized by engaging the shorter diameter portion 14b of the driven gear 14 and the seal 1 is located at the large diameter side end 2b of the package 2. Engagement of the driven gear 14 and the driven gear 16 is set such that the portion 16b is engaged with the long diameter portion 14a of the driven gear 14 to minimize the traverse speed. As a result, the small-diameter side end portion 2a becomes the maximum, and the large-diameter side end portion 2b becomes the minimum in the traverse angle θ of the package 2.

According to the present embodiment having the above configuration, the elliptical driving gear 16 and the driven gear 14 are used to pulsate the thread guide vanes 10a and 10b so that the traverse speed is increased by the conical package 2. And the engagement of the driving gear 16 and the driven gear 14 are set such that the traverse speed is fast at the small diameter end 2a of the package 2 and slowed down at the large diameter end 2b. As a result, the winding amount of the yarn 1 is small on the small diameter side of the package 2 and increases on the large diameter side, so that an appropriate conical package 2 having excellent shape can be obtained.

By the way, in the said blade traverse apparatus 9, as shown in FIG. 2, when the thread 1 is traversed from the small diameter side edge part 2a to the large diameter side edge part 2b, the traverse speed becomes slow gradually and large diameter side When traversed from the end portion 2b to the small diameter side end 2a, the traverse speed is gradually increased, but since the rate of change of those speeds is the same, the yarn wound from the small diameter side end 2a to the large diameter side end 2b The pattern of the traverse angle of (1) and the pattern of the traverse angle of the yarn 1 wound from the large diameter side edge part 2b to the small diameter side edge part 2a become the same.

Therefore, when the thread 1 of the conical package 2 which has been wound up is released in the next step, the pattern of the traverse angle of the thread 1 which is released from the small diameter side end 2a to the large diameter side end 2b and The pattern of the traverse angle of the yarn 1 released from the large diameter side end portion 2b to the small diameter side end portion 2a becomes the same, and the loosening property of the yarn is deteriorated. That is, in order to improve the loosening property of the yarn, the traverse angle of the yarn 1 at the time of releasing the yarn from the small diameter side end portion 2a to the large diameter side end portion 2b is set to the small diameter side end portion (from the large diameter side end portion 2b). Although it is desired to make it smaller than the traverse angle of the yarn 1 at the time of loosening a thread by 2a), in the said Example, the traverse angle pattern and the large diameter side end part 2b from the small diameter side end part 2a to the large diameter side end part 2b are mentioned. Since the traverse angle pattern from () to the small diameter side edge part 2a is the same, there exists a room for improvement in raising the loosening property of a thread.

If the description is virtually easy to understand using the average of the traverse speed, it can be described as follows. That is, in the previous embodiment, the traverse speed is actually varied along the axial direction of the package 2 as shown in the traverse angle θ of FIG. 2, but the maximum traverse speed is set to the small diameter side end portion 2a. Since the minimum traverse speed was made into the large diameter side edge part 2b, the average traverse speed from the small diameter side edge part 2a to the large diameter side edge part 2b, and the average traverse speed from the large diameter side edge part 2b to the small diameter side edge part 2a. And at the same speed.

Therefore, assuming that the yarn 1 is wound at the average traverse speed and the traverse angle is virtually shown, as shown in Fig. 4, the yarn wound from the small diameter side end 2a to the large diameter side end 2b ( The traverse angle of 1a) and the traverse angle of the yarn 1b wound up from the large diameter side edge part 2b to the small diameter side edge part 2a become equal. Considering the unwinding of the seal 1 of such a package 2, as shown in Fig. 3, the thread 1b wound from the large diameter side end 2b to the small diameter side end 2a is wound on the small diameter side end 2a. ), The traverse angle of the yarn 1b at the time of releasing to the large diameter side end portion 2b (the direction difficult to loosen), and the yarn 1a wound from the small diameter side end portion 2a to the large diameter side end portion 2b Since the traverse angle of the yarn 1a at the time of unwinding from the end portion 2b to the small-diameter side end portion 2a (the direction which is easy to loosen) becomes the same angle, the coiling property of the former yarn 1b deteriorates. will be. What is necessary is just to make small the traverse angle of the former thread 1b as shown by the dotted line 26, in order to improve the winding property of this thread 1b.

Thus, the inventor shifts the maximum traverse speed on the path from the small diameter side end portion 2a to the large diameter side end portion 2b as shown in FIG. 5, and at the same time, the minimum traverse speed is reduced at the small diameter side end portion 2b. It was conceived to set the engagement position of the driven gear 14 and the driven gear 16 so as to shift on the path to the side end 2a. In the case of this embodiment, the prime gear 16 and the driven gear 14 are driven in front of the long diameter portion 16a of the prime gear 16 and the driven gear at the small diameter side end 2a as shown in FIG. The front part of the short diameter part 14b of (14) is engaged, and the long diameter of the driven gear 14 and the immediately preceding part of the short diameter part 16b of the motive gear 16 in the large diameter side edge part 2b. The immediately preceding portion of the portion 14a is engaged.

By setting the engagement of the gears 14 and 16 in this way, the average of the traverse speed from the small diameter side end 2a to the large diameter side end 2b (indicated by the broken line 23 in Fig. 5) is the large diameter side end 2b. ) Is faster than the average of the traverse speed from the small diameter side end portion 2a (indicated by the dotted line 24 in FIG. 5). Therefore, assuming that the yarn 1 is wound at their average traverse speeds 23 and 24 and virtually showing the traverse angle of the yarns 1a and 1b, it is wound from the small diameter side end 2a to the large diameter side end 2b. As shown by the broken line 25 in FIG. 5, the yarn 1a is increased in traverse angle and the yarn length decreases so that the number of windings is reduced, and the yarn wound from the large diameter side end 2b to the small diameter side end 2a ( 1b), as shown by the dotted line 26 in FIG. 5, the traverse angle becomes smaller and the thread length becomes longer, thereby increasing the number of windings.

This package 2 has a yarn 1a (represented by a broken line 25 in FIG. 5) wound from the small diameter side end 2a to the large diameter side end 2b at the large diameter side end 2b at the small diameter side end 2a. 1b (represented by dashed line 26 in FIG. 5) wound out of the large diameter side end portion 2b and the small diameter side end portion 2a is the large diameter side end portion 2b at the small diameter side end portion 2a. Will be released. Accordingly, the traverse angle of the seal 1a when the package 2 is released from the large diameter side end portion 2b to the small diameter side end portion 2a that is easy to be loosened as shown in FIG. Corresponds to the broken line 25 of 5], and the loosening property of the thread is further increased, and when the thread 1b is released from the small diameter side end portion 2a that is difficult to be released from the large diameter side end portion 2b, The traverse angle becomes small as shown by the dotted line 26 (corresponding to the dotted line 26 in Fig. 5), so that the loosening property of the yarn becomes good.

Also in this embodiment, as shown in FIG. 5, the maximum traverse speed is set between the small diameter side end 2a and the center portion 2c of the package 2, and the minimum traverse speed is set to the large diameter of the package 2. Since it is set between the side end part 2b and the center part 2c, the traverse angle (theta) of the small diameter side end part 2a is the traverse angle (theta) of the large diameter side end part 2b like the previous embodiment shown in FIG. ), And the winding amount of the yarn 1 on the small diameter side is smaller than the winding amount of the yarn 1 on the large diameter side, so that an appropriate conical package 2 having a good shape can be obtained. That is, in this embodiment, in addition to being able to exert the effect of obtaining an appropriate conical package 2 having a good shape as in the previous embodiment, a package 2 having excellent unwinding property of the seal is provided. The effect that can be obtained can also be exhibited.

In addition, as shown in FIG. 1, the sensor 27 which detects the rotational speed of the package 2 is arrange | positioned in the vicinity of the bobbin holder 4 of the said package 2, and the output of the sensor 27 is carried out. A control unit 28 for adjusting the rotational speed of the drive motor 21 according to the present invention, and the control unit 28 packages the relationship between the rotation of the package 2 and the rotation of the seal guide vanes 10a and 10b. Regardless of the rotation speed of (2), it may be maintained in a predetermined relationship.

In this way, the automatic winder stops the friction drum 5 and the package 2 once at the time of cutting and removing the defective part of the seal 1, connects the seal 1, and then stops the stopped friction drum 5. Even if the friction of the friction drum 5 and the package 2 has occurred during restart, even if the rotation of the package 2 has not increased, the rotation of the package 2 by the sensor 27 and the control unit 28 and Since the relationship with the rotation of the thread guide vanes 10a and 10b is maintained in a predetermined relationship, an appropriate package 2 without entanglement can be formed.

That is, in a normal automatic winder, since the traverse drum (not shown) in which the traverse groove was engraved is brought into contact with the package 2 for rotation driving, the traverse drum is restarted when the traverse drum once stopped at the time of thread jointing or the like is restarted. If slip occurs between the drum and the package 2, entanglement occurs because only the transverse movement is made without the rotation of the package 2 being high.

In contrast, in the present embodiment, since the rotation of the package 2 and the rotation of the thread guide vanes 10a and 10b are always maintained in a predetermined relationship by the sensor 27 and the control unit 28, at the time of thread jointing, Even if slip occurs between the friction drum 5 and the package 2, the proper package 2 without entanglement can be formed.

The blade traverse apparatus shown in FIG. 12 rotates the two thread guide vanes b1 and b2 which were arrange | positioned by slightly shifting the rotating shafts a1 and a2 at the same speed, and is wound up by the package c to d. Presses at the side of the thread guide vane b to move along the thread guide plate e, and at the other end to the package c from the side of one thread guide vane b1 to the other thread guide vane ( By transferring to the side of b2), it reciprocates in the axial direction of the package c (refer Japanese Unexamined-Japanese-Patent No. 97-86793 etc.).

In such a wing traverse apparatus, when the thread d is traversed from the right side to the left side as the thread d is pressed on the side of the thread guide vane b and rolled over the thread guide plate e as shown in FIG. 13. When traversed from left to right, reverse twist is applied to the thread d. As a result, as shown in FIG. 14, the S twist part g and the Z twist part h alternately arise in the thread d wound by the package c.

The package c of the yarn d subjected to the alternating twist having periodicity is not preferable because of its low commodity value. For example, in the case where a package c wound around this yarn d is provided to a fabric weft yarn such as an air jet room, when the fabric width and the temporary twist are matched, as shown in FIG. This is a problem because streaks occur on the fabric i.

The vane traverse device of the automatic winder shown in FIGS. 8-11 has been studied so that twisting may not occur in a thread in consideration of the above circumstances, and this vane traverse device will be described below.

The automatic winder rewinds the yarn 1 released from the thread supply bobbin (not shown) to the conical winding package 2 while cutting off the defective portion of the yarn 1. The winding package 2 is supported so that the left and right ends thereof may be freely rotated by a holder (not shown), and is driven in contact rotation by the friction drum 5 shown in FIG. 10. In the vicinity of the friction drum 5, the wing traverse apparatus 9 for transversely moving the yarn 1 wound by the package 2 is arrange | positioned.

As shown in FIG. 8, the blade traverse apparatus 9 has two thread guide vanes 36a and 36b which overlap and arrange | position each rotation shaft 35a, 36b slightly. Each thread guide vane 36a, 36b is reversely rotated at the same speed with each other by the well-known gear mechanism accommodated in the gear case 37 shown in FIG. 11, and it is in both ends (traverse both ends) of the winding package 2, respectively. The gear ratio of the gear mechanism is set so as to overlap.

The thread holding parts 38a and 38b for holding the thread 1 toward the winding package 2 from the thread supply bobbin are provided in the both ends of each thread guide vane 36a, 36b, respectively. As shown in FIGS. 9A, 9B, and 9C, each of the thread holding portions 38a and 38b is arranged from the thread holding portion 38a of one of the thread guide vanes 36a to the other. In order to transmit to the thread holding | maintenance part 38b of the thread guide blade | wing 36b of this, it is formed in the step shape which the front of the thread guide blade | wing 36a, 36b is low in the rotation direction, and high in the rear.

In detail, the thread holding | maintenance part 38a, 38b is the low end part 39a, 39b of the rotation direction front of the thread guide vanes 36a, 36b, respectively, and the high end part of the rotation direction back, respectively. 40a and 40b and U-shaped hole parts 41a and 41b which are provided in these connection parts and hold | maintain the thread | substrate 1 substantially. The low end portions 39a and 39b and the high end portions 40a and 40b are point symmetrically at both ends of the wings 36a and 36b about the rotational axes 35a and 35b of the thread guide vanes 36a and 36b on which they are installed. Formed.

The U-groove-shaped ceramic parts may be inserted into the hole portions 41a and 41b to prevent abrasion. The high end parts 40a and 40b are formed in circular arc shape centering on the rotation shaft 35a, 35b of the thread guide vane 36a, 36b in which it was installed. As shown in FIG. 9A, FIG. 9B, and FIG. 9C, the lower end part 39b (also similar to 39a) has the thread | tip 1 hold | maintained at the thread holding part 38a of the thread guide vane 36a, and the thread guide vane ( It is formed in a tapered shape so as to be pushed out of the relative rotation of 36a and 36b and moved to the thread holding portion 38b, and serves as a thread separating portion (hereinafter referred to as reference numeral 39).

The seal separating portion 39b (the same applies to the reference numeral 39a) is used for the yarn 1 held in the hole portion 41a of the separate seal holding portion 38a, as shown in FIG. 9A. It is molded to be locked at the bottom, and the middle part is molded to push up the locked thread 1 upward in the hole portion 41a as shown in Fig. 9B, and the rear part is shown in Fig. 9C and Fig. 1. It is molded so that it may overlap with or become higher than the high end part 40a of the other thread holding part 38a, and it shape | molds in the taper shape in which the front part lowered than the said high end part 40a as a whole.

The delay amounts of the rotation shafts 35a and 35b of the guide vanes 36a and 36b are set. Thereby, the length from the rotation shaft 35a of the thread guide blade 36a to the high end part 40a, and the length from the rotation shaft 35b of the thread guide blade 36b to the back part of the seal | separation part 39b substantially correspond. Done.

According to this structure, whenever the two thread guide vanes 36a and 36b rotate relatively, and the thread guide vanes 36a and 36b overlap each other at both ends (traverse both ends) of the take-up package 2. 9A, 9B, and 9C, the seal 1 in the hole portion 41a of the holding portion 38a of the thread guide vane 36a on one side (upper side of the drawing) is the other side (lower side of the drawing). It is pushed up and pulled out by the thread separating part 39b of the thread guide vane 36b, and it can be reliably moved to the hole part 41b of the holding part 38b of the thread guide vane 36b on the other side (lower drawing). Can be.

Here, in order to improve the seal | separation property, the back part of the seal | separation part 39b of the lower | mold thread holding part 38b in FIG. 2 and FIG. 1 is used as the high end part 40a of the upper thread holding part 38a. It is preferable to mold it so as to be somewhat higher than). However, if the mold is made too high, the thread 1 is likely to be thrown off by the thread separating part 39b, and it is easy to be pulled out of the holding part 38b. Do. In fact, as shown in Figs. 2 and 1, if the upper end portion 40a of the upper thread holding portion 38a and the rear portion of the thread separating portion 39b of the lower thread holding portion 38b overlap with each other, Suffice.

According to the blade traverse apparatus 9 which consists of the above structure, the thread 1 hold | maintained and traversed by the thread holding part 38a of one thread guide blade 36a is shown to FIG. 9A, FIG. 9B, and FIG. 9C. Similarly, it is transmitted to the thread holding part 38b of the other thread guide vane 36b in the one end part of the winding package 2, and is traversed backward by the other thread guide vane 36b. The thread 1 traversed in the reverse direction by the other thread guide vane 36b is similarly formed at the other end of the winding package 2 to the thread holding unit 38a of one thread guide vane 36a. Delivered. In this way, the thread 1 is alternately transmitted to the thread holding parts 38a and 38b of the thread guide vanes 36a and 36b at both ends of the package 2, and reciprocally traversed.

Thus, according to the blade traverse apparatus 9 which concerns on a present Example, the thread holding part which installed the thread 1 which goes from the thread supply bobbin to the winding package 2 at the front-end | tip of each thread guide vane 36a, 36b. Since they alternately transmit and traverse in the air at 38a and 38b, the conventional guide shown in Fig. 5 makes the thread guide plate e necessary for guiding the thread d unnecessary, so that the thread d is threaded. The problem of the alternating twist of the yarn d shown in FIG. 14 caused by rolling in contact with the guide plate e can be avoided. Therefore, according to the blade traverse apparatus 9, the winding package 2 of the high quality with few kinks in the thread 1 can be manufactured.

Moreover, according to the blade traverse apparatus 9 which concerns on a present Example, since the thread 1 is hold | maintained by the thread holding parts 38a and 38b of the front-end | tip of each thread guide vane 36a, 36b, and is traversed in circular arc shape, The yarn path length from the yarn guide 42 shown in FIG. 11 to the winding point 43 of the package 2 via the thread holding parts 38a and 38b becomes substantially constant in traverse, and the yarn 1 wound up ) Tension fluctuation is suppressed. Therefore, the package of the appropriate shape with little winding fall can be obtained.

That is, in the conventional type shown in FIG. 12, since the thread d was pressurized by the side part of the thread guide vane b, and was traversed along the thread guide plate e, the said thread path | route is carried out at the both ends and center part of the package c. Although the length (refer FIG. 11) changed and the tension fluctuation | variation of the yarn d wound up was unavoidable, According to the vane traverse apparatus 9 which concerns on a present Example, as mentioned above, the yarn 1 was guided by a yarn. In order to hold | maintain at the front-end | tip of 38a, 38b, and to traverse by circular arc orbit, the said thread path length becomes substantially constant and the tension fluctuation of the thread 1 is suppressed.

By the way, since the automatic winder to which the said wing traverse apparatus 9 is mounted is wound again on the winding package 2, cutting | disconnecting and removing the defective part of the thread 1 of a thread supply bobbin, the thread which should remove the defective part (1) may be cut | disconnected. At this time, the cut thread 1 has its upper thread 1a on the winding package 2 side and its lower thread ab on the thread supply bobbin side, but they are held in a known section mouse, respectively. And a seal connecting device 44 shown in FIG. 11, and are connected there.

Since the position of the thread 1 connected in this way is indeterminate, it is withdrawn from the thread holding part 38b (38a) of the thread guide vane 36b (36a) normally as shown in FIG. 9A, 9B, and 9C, when the thread 1 is delivered and traversed, it is conceivable that the thread 1 is pulled out of the thread holding portions 38a and 38b for some reason. . In this way, when the thread 1 is removed from the thread holding portions 38a and 38b, the thread 1 must be inserted back into the thread holding portions 38a and 38b, and therefore, the invention is shown in FIGS. 10 and 11. The holding plate 45 is shown.

As shown in the drawing, the holding plate 45 is disposed along the axial direction of the winding package 2 near the lower side of the thread guide vanes 36a and 36b, and from the thread holding portions 38a and 38b at the time of thread connection or the like. It has the thread contact part 46 which the missing thread 1 contacts. The thread 1 removed from the thread holding portions 38a and 38b is brought into contact with the thread contact portion 46 of the holding plate 45 because it is pulled with a predetermined tension between the winding package 2 and the thread supply bobbin. As shown in Fig. 10, the thread contact portion 46 is formed in a mountain shape across the arc trajectory of the thread separating portion 39b (39a) accompanying the rotation of the thread guide vane 36b (36a). It is molded at a height lower than the arc trajectory of the hole 41b (41a) accompanying the rotation of the thread guide vane 36b (36a).

According to this configuration, as shown in Fig. 10, the thread 1, which is pulled out of the thread holding portion 8b and held at the thread contact portion 46 of the holding plate 45 at the time of thread connection or the like, has a thread contact portion 46. Since it is molded in the shape of a mountain crossing the arc trajectory of the thread separating part 39b, the thread separating part of the thread holding part 38b of the thread guide wing 36b is restarted by the rotation of the thread guide wing 36b. It floats to 39b and automatically fits back into the hole 41b of the thread holding part 38b. In addition, since the thread contact portion 46 is formed at a height lower than the arc trajectory of the hole portion 41b, the yarn 1 sandwiched by the hole portion 11b does not interfere with the thread contact portion 46 during traverse. There is no alternating twist caused by contact.

That is, the retaining plate 45 according to the present embodiment shown in Figs. 10 and 11 is similar in shape to the seal guide plate e of the conventional type shown in Fig. 12, but its function is completely different, and the seal guide plate of the conventional type ( There is no function of guiding the thread (d) traversed as in e), in order to reinsert the thread (1) removed from the thread holding portions (38a, 38b) to the thread holding portions (38a, 38b) again at the time of thread connection. After temporary holding, after reinserting into the thread holding parts 38a and 38b, it is not in contact with the thread 1.

However, at both ends of the traverse (refer to FIG. 9C), as shown by the imaginary line 47 in FIG. 10, the seal 1 in the hole 41b (the same in 41a as well) is held by the holding plate 45. The two end portions of the seal contact portion 46 may be molded so as to be press-contacted to the seal contact portion 46 to assist the separation of the seal. In this way, as shown in FIGS. 9A, 9B, and 9C, the thread 1 in the hole 41a (41b) is the thread separating portion 39b (39a) of the other thread guide vane 36b (36a). In addition to the separation of the seals, the seals are press-closed to the seal contact portion 46 of the retaining plate 45 as shown by the virtual line 47 in FIG. Since the position at which the thread 1 is pulled out is stabilized at the same time, the delivery timing is provided.

In addition, since the holding plate 45 is installed to cover the lower side of the thread guide vanes 36a, 36b that rotate at high speed as shown in FIG. 11, it also serves as a safety cover. In addition, in FIG. 10, it is transmitted from one thread guide vane 36a (36b) to the other thread guide vane 36b (36a) to the position which opposes the traverse left and right both ends of the holding plate 45. In FIG. An auxiliary guide (not shown) for pressing the thread 1 from above may be provided respectively.
