[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of traversing a yarn by rotating two rotating blades in opposite directions along a yarn guide for forming a traverse trajectory of the yarn having folding points at both left and right ends. The present invention relates to a traverse device capable of transferring a yarn between two rotating blades at a turning point.

[0002]

2. Description of the Related Art FIG.
Are known. An arcuate thread guide 101 for forming a traverse locus of the thread is provided, and the thread traverses (reciprocates) between points A and B at both left and right ends of the thread guide. Two rotating blades 102 and 103 are arranged vertically above and below the yarn guide 101. The lower rotating blade 102 is attached to a clockwise rotating shaft 104, and the upper rotating blade 103 is attached to a counterclockwise hollow shaft 105 that is coaxial with the rotating shaft 104. Therefore, the two rotating blades 102 and 103 rotate in opposite directions at a predetermined interval H. The tip 102a of the lower rotating blade 102 is B
The leftward traverse from point A to point A is in charge, and the tip 103a of upper rotating blade 103 is responsible for rightward traverse from point A to point B.

[0003] The left side of the drawing shows the delivery state of the yarn at the return point A, and the right side of the figure shows the delivery state of the yarn at the return point B. At the turning point A, the thread is transferred from the tip 102a of the lower rotating blade 102 to the tip 103a of the upper rotating blade 103, and at the turning point B, the upper rotating blade 1
03, the tip 10 of the rotating blade 102 below the tip 103a.
The thread is delivered to 2a.

In order to transfer the yarn, a yarn guide 10 is provided.
Auxiliary guides 106, 107, 108, and 109 are provided above and below 1 and near turning points A and B. At the turning point B, the auxiliary guide 106 protrudes inward and locks the thread to the left-hand tip 102a, and the auxiliary guide 107 protrudes outward to release the thread at the right-hand tip 103a. Let open. At the turning point A, the auxiliary guide 109 protrudes inward and locks the thread to the right-hand tip 103a, and the auxiliary guide 108 protrudes outward to release the thread at the left-hand tip 102a. Let open. Thus, the auxiliary guide 10
The transfer of the yarn at the turning point B is realized at 6, 107,
The transfer of the yarn at the turning point A is realized by the auxiliary guides 108 and 109.

[0005] The left and right turn points A and B in such a traverse device are used to stabilize the traverse.
The left and right sides are arranged so as to be uniform. That is, the turning points A and B on the left and right correspond to the traverse center line 1 at the point X shown in the figure.
10 are provided at symmetric positions of the left and right, and the auxiliary guides 106, 1
Reference numerals 07, 108, and 109 are also arranged at the point target positions of the illustrated point O. Among known traverse devices, there is a type in which the center of rotation of the upper and lower rotating blades is eccentric to transfer the yarn at the left and right turning points A and B without an auxiliary guide. An intermediate position between the two rotation centers is a traverse center line, and left and right turn points A and B are disposed at left and right target positions of the traverse center line.

[0006]

However, a pair of auxiliary guides 106 and 107 are provided between the upper and lower rotating blades 102 and 103 at the turning point B, and similarly, the upper and lower rotating blades 102 and 103 at the turning point A are provided. Since the pair of auxiliary guides 108 and 109 are disposed between the two points, there is a problem that the degree of bending of the yarn at the folding points A and B is increased, and the damage to the yarn is increased. Therefore, if the distance H between the upper and lower rotating blades 102 and 103 is increased to reduce the degree of bending of the yarn,
There will be a distance difference corresponding to the distance H between the height at which the rotating blades 102 for the leftward traverse hangs the thread and the height at which the rotating blades 103 for the rightward traverse hangs the thread. The delicate balance between the left and right turn points A and B is lost due to the distance difference H between the heights at which the thread is hung.

Accordingly, the present invention has been made in view of the above-mentioned problems of the prior art, and the arrangement of a pair of rotating blades is necessarily up and down with respect to the running direction of the yarn. An object of the present invention is to provide a traverse device capable of reducing the degree of bending of the yarn at the left and right turn points of the traverse device and forming the right and left turn points in a well-balanced manner.

[0008]

In order to achieve the above object, according to the first aspect of the present invention, a yarn guide having a guide surface for forming a traverse trajectory and a yarn guide along the yarn guide are provided. A traverse device comprising: two rotating blades that rotate in opposite directions and are disposed above and below in the yarn running direction, the rotation center of the two rotating blades,
Traverse center is coaxial, in order to assist the transfer of the yarn of the rotary blade to each other at the turning point of the traverse path, from the previous Quito traverse center until the guide surface of the left and right at the turning point of the yarn guide distance provided the difference, passing with an auxiliary guide you assist the yarn at the turning point of the traverse path in addition to the yarn guide, the auxiliary guide and the yarn guide and the top and bottom of the two rotary blades characterized in that the disposed so as to sandwich. Since the distance between the center of the traverse and the guide surfaces on the left and right is made different and the role of one of the conventional pair of upper and lower auxiliary guides is given to the yarn guide, the bending of the yarn can be reduced. Further, on one side of the left and right turning points, the action of locking the yarn to the blade is achieved by the action of the yarn following the yarn guide using the tension of the traveling yarn. With this configuration, the yarn can be transferred by the auxiliary guide 4 arranged only on the center side of the traverse across the traverse trajectory as shown in FIG. 2, so that bending of the yarn on one side of the turning point can be reduced. Further, by disposing the two rotating blades on one of the lower surface and the upper surface of the yarn guide, the distance limitation of the yarn guide between the rotating blades is eliminated, and the upper and lower rotating blades can be arranged close to each other. When the blades are arranged close to each other, the distance between the blade and the touch roller or the friction roller becomes substantially the same in the upper and lower directions, so that the delay of the yarn movement in the traverse direction due to the free length can be equalized in the left and right directions. According to a second aspect of the present invention, in addition to the configuration of the first aspect, the guide surface of the yarn guide has an arc portion, and the center of the arc portion and the center of the traverse are eccentric to each other. The distance difference of the yarn guide at the turning point is formed. When the distance difference is formed by eccentricity of the yarn guide having an arc portion, the protrusion amount of the yarn guide is smoothly changed so that the increase in tension is reduced at both ends and the decrease in tension is reduced at the center. The invention according to claim 3 is the invention according to claim 1 or 2
In addition to the configuration of the invention described above, an overlap section is provided in which the two rotating blades simultaneously lock the yarn when transferring the yarn at the turning point of the traverse locus. Due to the overlap section in which the two rotating blades simultaneously lock the yarn, the positions of the left and right turning points are stabilized. In the case where an overlap section is provided, the yarn guide is provided above or below the upper and lower rotating blades, and the interval between the rotating blades is 0.75 of the blade thickness of the rotating blade.
The range is up to three times. If the interval is less than 0.75 times the thickness of the blade, the yarn will be rubbed too much between the blades, and if severe, the yarn will break. If the interval exceeds three times the blade thickness, the distance between the blades becomes unnecessarily wide, and the degree of making the right and left turning points nonuniform exceeds the degree. Preferably, the arrangement of the yarn guide and the like is devised so as to keep the interval at about 0.75 to 1.25 times the blade thickness.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a main part of the traverse device of the present invention, FIG. 2 is a diagram showing a thread transfer state at a left turn point A, and FIG. 3 is a diagram showing a thread transfer state at a right turn point B. It is.

Usually, the traverse device is constituted by arranging a plurality of traverse units U1, U2, U3. FIG.
Shows one traverse unit U1. 1
Is a thread guide disposed eccentrically to one of the left and right sides of the traverse center, 2 is a rotating blade that is positioned on the upper side and rotates counterclockwise around the traverse center, and 3 is positioned on the lower side. Rotating blades that rotate clockwise around,
Reference numeral 4 denotes an auxiliary guide at the turning point A, and reference numeral 5 denotes an auxiliary guide at the turning point B. These are main parts of one traverse unit.

Reference numeral 11 denotes a touch roller or a friction roller, 12 denotes a bobbin holder, and 35 denotes a bobbin holder.
Is a package in which a thread is wound around the bobbin 35. Reference numeral 15 denotes the auxiliary guide 4 and the block 1
Reference numeral 17 denotes a bracket that supports the auxiliary guide 5 via a block 16.

As shown in the state diagram of the turning point A in FIG. 2, the thread guide 1 is located above the upper and lower rotating blades 2 and 3, and the touch roller 11 is located below the upper and lower rotating blades 2 and 3. An auxiliary guide 4 protruding outward from the side is located. That is, the auxiliary guide 4 is disposed only on the traverse center side with respect to the traverse locus. The whole is arranged so as to diagonally cross the upper and lower yarn paths of the yarn Y along the touch roller 11. At this turning point A, the yarn is transferred from the lower rotating blade 3 to the upper rotating blade 2. At a point C, the rotating blades 2 traverse the yarn in the rightward direction in FIG. The yarn guide 1 is responsible for locking the yarn to the upper rotating blade 2, and the yarn guide 1 not only determines the traverse trajectory but also assists in the transfer of the yarn. Since the auxiliary guide 4 for assisting the transfer of the yarn together with the yarn guide 1 is only for removing the yarn from the lower rotating blade 3, the degree of bending of the yarn in the auxiliary guide 4 is minimized so as not to hinder the transfer of the yarn. It is kept to the limit. Thus, the yarn guide 1
Since the auxiliary guide 4 and the auxiliary guide 4 are inside the traverse trajectory (the traverse center side), the bend of the yarn is not a zigzag but a mere “K” shape as is clear in comparison with FIG.

As shown in the state diagram of the turning point B in FIG. 3, the upper and lower rotating blades 2,
The structure in which the thread guide 1 is disposed on the top 3 is the same as that in FIG. However, the auxiliary guide 5 below the rotary blades 2 and 3 is positioned so as to protrude inward from the side opposite to the touch roller 11. That is, the auxiliary guide 5 is arranged only on the opposite side of the traverse center side with respect to the traverse locus. At this turning point B, the yarn is transferred from the upper rotating blade 2 to the lower rotating blade 3. At point D, a state is shown in which the rotating blades 3 traverse the yarn leftward in FIG. 1 along the yarn guide 1. The yarn guide 1 is responsible for removing the yarn from the upper rotating blades 2. The yarn guide 1 not only determines the traverse trajectory but also assists in the transfer of the yarn. Since the auxiliary guide 5 locks the yarn on the lower rotating blade 3, the degree of bending of the yarn in the auxiliary guide 5 is larger than that of the auxiliary guide 4. As described above, since the yarn guide 1 and the auxiliary guide 4 are located on both sides of the traverse trajectory, the bending of the yarn is not a simple "C" shape but a zigzag as clearly seen in comparison with FIG. . However, since the degree of bending of the yarn at one of the turning points A and B of the left and right yarns is reduced, the damage to the yarn is reduced. Also, as compared with a yarn guide between the rotary blades and a pair of auxiliary guides for assisting the transfer of the yarn, a yarn guide 1 disposed above and below the rotary blade and only one auxiliary guide 4 at the right and left turning points. 2 and 3, in which the yarn is transferred at 5, 5, the degree of bending of the yarn can be reduced.

As described above, in order to provide the yarn guide 1 with a function of assisting the transfer of the yarn and to change the degree of bending of the yarn at the left and right turn points, the yarn guide 1 is eccentrically arranged with respect to the center of the traverse. . This eccentric arrangement will be described with reference to FIG. O1 is the rotation center of the rotating blades 2, 3 in the traverse unit U1, ie, the traverse center, and O2 is the rotation center of the rotating blades in the adjacent traverse unit U2, ie, the traverse center. This traverse center O
A line connecting 1, O2 is a reference line 13 aligned with the traverse locus, and a line perpendicular to the reference line 13 is a traverse center line 14. In the yarn guide 1, an arc portion having a radius R forms a guide surface. The center O of the radius R of the thread guide 1
O is typically above the traverse centerline 14, but is shifted to the right by a distance ε in an embodiment of the present invention. In accordance with this eccentricity, the left and right auxiliary guides 4, 5 and the mounting brackets 15, 17 are also generally arranged rightward.

As a result, at the traverse center O1, the angle α between the left turning point A and the traverse center line 14 is formed.
Is smaller than the angle β formed between the right turning point B and the traverse center line 14 at the traverse center O1. The distance L1 from the traverse center O1 at the left turning point A to the guide surface of the thread guide 1 is shorter than the distance L2 from the right turning point B to the guide surface. Further, the distance M1 between the left turning point A and the traverse center line 14 is shorter than the distance M2 between the right turning point B and the traverse center line 14.

Although the yarn guide having the circular arc portion 1a is eccentric as described above, since the traverse locus is determined by the circular arc portion 1a, the tension increase is mitigated at both ends of the traverse locus, and the tension is reduced at the central portion. There is no hindrance to the original function of the yarn guide, which is to alleviate the tension. That is, a function of assisting the transfer of the yarn can be added only by eccentrically disposing the yarn guide having the arc portion 1a with respect to the center of the tochiverse, and the degree of bending of the yarn at one of the left and right return points can be reduced. It is possible to reduce the damage of the thread by reducing it.

As described above, the left and right turn points A and B are non-uniform with respect to the traverse center line 14.
The directions of the auxiliary guide 4 and the auxiliary guide 5 are also non-uniform. However, by reducing the degree of bending of the yarn at at least one of the left and right turn points, damage to the yarn is reduced. In short, it is important to reliably transfer the yarn at the left and right turn points while reducing the damage to the yarn, and as a result, only the left and right non-uniformity occurs.

In order to reduce the difference in free length between the upper and lower rotating blades 2 and 3 and the touch roller (or friction roller) 11, it is preferable to arrange the upper and lower rotating blades 2 and 3 close to each other. Therefore, the thread guide 1 is disposed above the upper and lower rotating blades 2 and 3, and the auxiliary guides 4 and 5 are disposed below the upper and lower rotating blades 2 and 3. As a result, the distance between the tips of the blades 2 and 3 and the touch roller (friction roller) 11 becomes substantially equal at the left and right turn points, and the delay of the yarn movement in the traverse direction due to the free length is made equal to the left and right, and the distance between the ends of the package is reduced. Left and right shapes can be the same.

The turning points A, left and right in FIGS.
In B, the upper rotating blade 2 in the counterclockwise direction and the lower rotating blade 3 in the clockwise direction transfer the yarn as shown in the drawing through an overlap section in which the yarn is conveyed in opposite directions. By providing an extremely short overlap section, the yarn becomes free at the time of the transfer of the yarn and naturally returns to the center position of the traverse width due to the yarn tension, thereby preventing the package shape from being collapsed due to the unstable traverse width. . In the case where such an overlap section is provided, if the interval δ1 between the upper and lower rotating blades 2 and 3 is too small, the yarn Y is handled too much. Therefore, the interval δ1 needs to be suppressed to about 0.75 to 3 times the thickness δ2 of the portion where the yarns of the rotating blades 2 and 3 are hooked. A more preferable interval δ1 is 0.75 of the thickness δ2.
1.25.

Next, a more detailed structure of the above-described traverse device will be described with reference to FIGS. 4 and 6, the upper rotating blade 2 has a slightly smaller diameter than the lower rotating blade 3, and even if the upper and lower rotating blades 2 and 3 are arranged obliquely, the ends of the rotating blades 2 and 3 are vertical. It almost follows Y. As clearly shown in FIG. 6, the upper rotating blade 2 has two tips 2a and 2b which are symmetric with respect to the center O1 and are separated by 180 °, and the lower rotating blade 3 is also located at the center O1. On the other hand, it has two tips 3a and 3b which are point objects and are 180 ° apart. At the turning point B, the yarn is transferred from the upper end 2a to the lower end 3a, and the lower end 3a reaches the turning point A and the upper end 2b
Also reaches the turning point A. After all, while the rotating blades 2 and 3 make one rotation in the opposite direction, the two tips 2a, 2b, 3a and 3b make the yarn reciprocate once along the traverse locus determined by the yarn guide 1 and the auxiliary guides 4 and 5. The number of the tips of the rotating blades 2 and 3 is not limited to two, and may have three tips equally spaced at 120 °. Further, one rotating blade may have two tips and the other rotating blade may have three tips, and the angular velocities of rotation may be different in inverse ratio.

As described above, the yarn guide 1 has an arc portion 1a as a guide surface, and the center OO of the radius R of the arc portion 1a is shifted rightward from the traverse center line 14 by ε. is there. However, the thread guide 1 is not limited to the one having the arc portion, and may be a parabolic portion. In this case, the distance L1 <L2 from the traverse center O1 is satisfied.

Auxiliary guides 4 and 5 for assisting the transfer of the yarn via a bracket attached to the yarn guide 1 are provided below the rotary blades 2 and 3, and the yarn guide 1 and the auxiliary guides 4 and 5 are provided. The rotating blades 2 and 3 are sandwiched from above and below. The auxiliary guide 4 has an outward guide surface 4a, and the auxiliary guide 5 has an inward guide surface 5a facing the traverse center O1. The bracket 15 shown in FIG. 1 has a guide surface 15a that deviates from the traverse path along the yarn guide 1. When the bobbin is changed by rotating the turret, the yarn removal guide 41 and the yarn pulling guide 46 are provided.
Is a surface for holding the yarn detached from the rotating blades 2 and 3 by the action of the above. When the yarn is on the guide surface 15a, the yarn does not traverse and a bunch winding at the end of the bobbin 35 can be formed. . When the yarn slips off the guide surface 15a, the traverse of the yarn starts as described above. In the configuration in which the left and right auxiliary guides 4 and 5 are supported from below the rotating blades 2 and 3, the mounting brackets 15 and 17 are unnecessary. However, although it is unnecessary, by providing the guide surfaces 15b and 17a on the mounting brackets 15 and 17, it is possible to reliably prevent the yarn from coming off at the transfer portion.

FIGS. 4 and 5 show a yarn pulling guide and a yarn removing guide for preventing the yarn from traversing during bobbin chain switching between the full bobbin and the empty bobbin.
This will be described below. In this bobbin change, first, the yarn is removed from the traverse trajectory determined by the circular arc portion 1a of the yarn guide 1, and the first stop for releasing the engagement between the ends of the rotary blades 2, 3 and the yarn is performed.
In the process, the yarn that is deviated from the traverse trajectory and is going to become the yarn path vertically in the nature is forcibly shifted to the left end of the bobbin 35,
The second step of performing the yarn transfer in which the yarn is hung on the slit of the empty bobbin while preventing the yarn from coming off from the end of the full bobbin, and the third step of forming a bunch winding outside the traverse range of the yarn of the empty bobbin are sequentially performed. Is what you do.

The first step is a yarn removing guide 4 shown in FIG.
1 is performed. The thread removing guide 41 also serves as an upper cover of a traverse device composed of a large number of traverse units.
It is slidable in a plane parallel to. Normally, the guide surface 41a of the yarn removing guide 41 does not interfere with the yarn Y, but when the yarn removing guide 41 slides and protrudes as shown by a two-dot chain line, the yarn Y is pushed forward by the guide surface 41a, and the rotating blade 2 , The traverse is stopped. FIG.
As clearly shown in FIG. 4, the yarn removal guide 41 is plate-shaped, and has a rectangular cutout 4 communicating with the yarn introduction portion 41b.
1c is provided. A surface of the cutout 41c with respect to the yarn guide 1 is a guide surface 41a.

The above-mentioned second step is performed by the yarn removing guide 4 shown in FIG.
The yarn pulling device 43 provided upstream of the first guide surface 41a
Done by Yarn puller 4 shown in detail in FIG.
Reference numeral 3 denotes a fixed guide tube 44, a rod 45 inserted into the guide tube 44, a thread guide 46 projecting vertically from the rod 45, and a rod 45 with respect to the guide tube 44. And a drive cylinder 47 for moving forward and backward. Guide tube 44
In this case, the yarn guide 46 is turned 90 ° from a vertically upward retreat position parallel to and away from the yarn path to a position intersecting with the yarn path, and is further moved in the traverse direction of the yarn with the posture intersecting with the yarn path. A cam groove 44a is provided.

The above-described third step is performed by the guide surface 15a in FIG. 1 for preventing the yarn from traversing even when the yarn removing guide 41 is at the position indicated by the solid line. The guide surface 15a is partially visible from the cutout 41c in FIG.

An outline of the bobbin change by the yarn removing guide 41, the yarn moving device 43, and the guide surface 15a is as follows. The yarn Y normally traverses along the circular arc portion 1a of the yarn guide 1. At the timing of bobbin change, first, the yarn removing guide 41 projects from the solid line position to the two-dot chain line position in the direction of the arrow a1. Then, the yarn Y comes off the tip of the rotating blade. At the same time, the cylinder 47 of the yarn pulling guide 43 extends in the direction of arrow a2,
Takes a posture intersecting with the yarn Y as indicated by the arrow a3, moves further in the direction of the arrow a4, hooks the yarn Y, and moves the yarn to the left end outside the traverse range. Thereafter, the yarn transfer from the full bobbin to the empty bobbin is performed by a yarn transfer device (not shown). Thereafter, a bunch winding is formed between the slit of the empty bobbin and the end of the traverse range. Therefore, the yarn removing guide 41 returns in the direction of the arrow a5, but the yarn guide 46 at the position where the bunch winding can be formed is left as it is. Then, the yarn Y is regulated by the guide surface 15a and does not hit the tip of the rotating blade, so that a bunch winding is formed. Then, when the drive cylinder 47 is shortened in the direction of arrow a6, the yarn Y
The traverse begins to be released from the end of 5a and locked by the tip of the rotating blade, and the yarn reciprocates.

A timing pulley 29 is provided on the pulley 28 side of the drive shaft 27, and a gear 30 is mounted on the opposite side of the pulley 28. Then, a timing pulley 32 meshing with the timing belt 31 hung on the timing pulley 29 is attached to the center shaft 23,
The center shaft 23, that is, the lower rotating blade 3 rotates in the same direction as the drive shaft 27. A gear 33 that meshes with the gear 30 is attached to the hollow body 25, and the hollow body 25, that is, the upper rotating blade 2 rotates in a direction opposite to the drive shaft 27.

[0030]

As described above, according to the first aspect of the present invention, the role of one of the conventional pair of upper and lower auxiliary guides is assigned to the yarn guide to reduce the bending of the yarn. By reducing the bending of the yarn on one side of the left and right turn points, the damage of the yarn as a whole package can be reduced. In addition, the left and right shapes of the package ends can be made the same by eliminating the restriction of the yarn guide between the rotating blades and equalizing the delay of the yarn movement in the traverse direction due to the difference in free length.
That is, it is possible to form a good package while reducing damage to the yarn. According to the second aspect of the present invention, in addition to the effect of the first aspect, the eccentric arrangement of the yarn guide having an arc portion reduces the tension increase at both ends and reduces the tension decrease at the center. The amount of protrusion changes smoothly, and the function of an auxiliary guide for thread transfer is ensured, and the effect of obtaining a uniform package in the traverse direction is also ensured. According to the third aspect of the invention, in addition to the effects of the first or second aspect, by stabilizing the positions of the left and right turning points, the balance between the left and right turning points can be further ensured.
