BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotor type open end spinning machine and a method of jointing a yarn.

In general, in a rotor-type open end spinning machine, feed slivers are loosened by a combing roller to separate impurities, and the loosened fibers are in the fiber transport passage based on the negative pressure in the rotor where the loosened fibers are rotated at high speed. The generated airflow is transported into the rotor.

Then, the fiber transported in the rotor is connected to the fiber focusing portion (fiber focusing groove), which is the largest inner diameter of the rotor, and is drawn out from the guide hole (actual drawing passage) formed in the center of the navel, and acts as a roller. It is drawn while being twisted and wound as a package on the bobbin.

That is, in the rotor-type open-end spinning machine, the fiber bundles focused on the fiber focusing part are separated from the fiber focusing part and drawn out along the wall surface of the guide hole formed in the center of the navel.

Then, the fiber bundle is pulled out while rotating along the inner wall surface of the guide hole as the rotor rotates, and the fiber bundle is twisted.

However, the fiber bundle focused on the fiber focusing part is only attached to the inner wall surface of the fiber focusing part by the action of centrifugal force accompanying the rotation of the rotor.

Therefore, the twist applied to the fiber bundle drawn out while rotating along the guide hole propagates to the fiber bundle before being pulled out as a thread in a state in which it is attached to the fiber bundle, and the fiber bundle in the fiber bundle rotates.

As a result, there is a problem that the fiber is not twisted straight and the strength of the thread does not rise because the twist is applied in a state where sufficient tension is not obtained when the twist starts and the fiber is not sufficiently stretched.

In order to solve this problem, Japanese Patent Laid-Open No. 51-64034 proposes the apparatus shown in Figs. 46 and 47.

In this apparatus, a disc-shaped inner rotor 93 is provided inside the outer rotor 92 having the fiber focusing portion 91.

The inner rotor 93 automatically rotates with respect to the outer rotor 92. In the inner rotor 93, a hole in which a conduit pipe (thread drawing tube) 94 is loosely fitted is formed in the center thereof, and the hole is drawn out to pull out the fiber bundle F focused on the fiber converging portion 91. Intersect the hole 95 at right angles.

The inner rotor 93 is provided with a small disc (shown in FIG. 47) which revolves and rotates while being in compression contact with the fiber bundle focused on the fiber converging portion 91.

The apparatus rotates faster than the external rotor in a state where the internal rotor 93 has a predetermined rotation difference with the external rotor 92 so that the fiber bundle F connected to the fiber connecting part 91 is drawn out. Withdraw via).

This spins while giving a bundle to the fiber bundle F.

In addition, the action of the small plate 96 allows the spinning of the fiber bundle F while being stable while spinning.

In addition, the present applicant is an apparatus that prevents the twist applied to the fiber bundle from propagating to the fiber bundle before being pulled out as a thread in the state of being attached to the fiber bundle, and the internal rotor that is actively driven independently of the external rotor. And a thread passage for guiding the fiber bundle from the vicinity of the fiber focusing portion to the position facing the thread drawing passage in the inner rotor, and a twist propagation preventing portion provided at the side surface of the fiber focusing portion of the thread passage. Is proposing.

However, in the above-described conventional apparatus in which the inner rotor is provided in the outer rotor, the inlet of the thread passage leading the fiber bundle separated from the fiber converging portion to the thread take-out passage (hole) is narrow, so that the thread take-out passage ( Seed thread inserted into the thread passage is hard to reach the fiber focusing part.

As a result, there was a problem that the real voice success rate was low.

Moreover, when the twist propagation prevention part is provided in the fiber concentrating side side part of a thread passage, there exists a problem that seed | leave is hard to reach | attach by a fiber converging part.

The present invention has been made in view of the above-described problems, and an object thereof is a rotor-type open end spinning machine having an inner rotor capable of reliably reaching the tip of the seed chamber to the fiber converging portion of the outer rotor at the time of thread joining. And a method of jointing the yarns.

In order to achieve the above object, the invention described in claim 1 is actively driven independently of an external rotor in an external rotor having a fiber focusing portion in which fibers supplied in a loose state are focused, and at the same time, a part of the single drawing passage of the actual draw passage. In the rotor-type open end spinning machine provided with a coaxial line with an external rotor, the inner rotor of the fiber bundle which is drawn out of the fiber concentrating unit during normal spinning and moves to the thread drawing passage as described above. The position where the seed chamber is introduced at the time of the movement of the former and the joint of the yarn was made into a separate position.

Further, in the invention described in claim 2, in the rotor-type open end spinning machine provided with the inner rotor and the outer rotor, the fiber bundle drawn out from the fiber concentrating portion at the time of normal spinning is applied to the inner rotor. Withdrawal thread passage for guiding one thread draw passage, an introduction thread passage for introducing a seed thread during thread joining through the draw chamber passage described above, and a fiber bundle drawn out from the fiber concentrating part during normal spinning. A regulating means is provided which is engaged and regulates the fiber bundle at a predetermined position in the drawer passage described above.

In the invention according to claim 3, in the rotor-type open end spinning machine described in claim 2, the above-mentioned regulating means is provided at a position opposite to the open end terminal of the outer rotor than the plane in which the fiber converging portion exists. At the same time, the inner rotor is provided with a guide surface for guiding the fiber bundle drawn out by the working chamber introduced into the introduction chamber passage to the above-mentioned regulating means.

In addition, in the invention disclosed in claim 4, the inner circuit corresponding to the terminal portion of the actual draw passage is driven actively while being actively driven independently of the external rotor in the external rotor having the fiber focusing portion where the fibers supplied in the released state are focused. In a rotor-type open end spinning machine in which electrons are installed on the same side as the external rotor, a yarn passage and a yarn for guiding the fiber bundle from the vicinity of the fiber connection part to the above thread take-out passage during normal spinning on the inner rotor. In parallel with the passage, at the same time, a wider introduction passage was formed than the inlet portion of the actual passage, and a regulating means for regulating the movement of the fiber bundles introduced into the aforementioned passage toward the introduction passage side was provided.

In the thread joint method according to claim 5, the seed chamber is continuously connected to the thread passage in a state in which the external rotor and the inner rotor are rotated at the time of thread jointing, and at the same time, the thread joint is wider from the inlet of the thread passage. The tip of the seed thread reaches the fiber converging part by inserting it from the thread drawing passage to the introduction passage, and together with the seed thread, the fiber bundle of the fiber converging part is withdrawn from the thread drawing passage via the introduction passage, and then the fiber bundle is threaded from the introduction passage. Moved to the passage to continue low radiation.

In the present invention, the released fibers sent from the fiber transport passage into the external rotor are slid along the wall surface of the rotor and focused on the fiber concentrating portion.

One end of the fiber bundle focused on the fiber converging portion is connected to a thread to be drawn out by the drawing roller.

The fiber bundle is pulled out of the fiber converging portion and drawn out from the thread take-out passage while being twisted by the rotation of the internal rotor.

In general, the position where the fiber bundle is moved at the time of spinning and the position at which the seed thread is introduced at the joint of the yarn become separate positions.

In the invention as set forth in claim 2, the fiber bundle drawn out from the fiber converging portion is normally engaged with the restricting means so as to pass through a predetermined position of the drawing chamber passage provided with the internal rotor.

At the joint of the thread, the seed chamber is introduced into the outer rotor through the guide surface formed on the inner rotor from the thread passage for introduction of the inner rotor.

In the invention according to claim 3, the fiber bundle drawn out from the fiber focusing section is not drawn out directly toward the central axis of the external rotor from the point of detachment of the fiber focusing section, but is drawn out toward the restriction means.

Therefore, the force required to detach the fiber bundle from the fiber concentrating portion against the centrifugal force caused by the rotation of the external rotor is reduced.

In addition, the seed chamber introduced into the thread passage for introducing the internal rotor from the thread takeout passage at the time of the joint of the thread is moved to a position engaged with the above-mentioned restriction means by moving on the guide surface formed on the internal rotor.

Further, in the inventions of claims 4 and 5, the seed chamber in which the external rotor and the internal rotor are rotated is inserted into the introduction passage from the thread take-out passage at the time of the joint of the yarn.

In the seed chamber, the terminal of the chamber is introduced into the external rotor by the negative pressure in the external rotor, and reaches the fiber focusing section by the action of the centrifugal force.

Since the introduction passage is wider than the actual passage, the seed chamber smoothly moves into the introduction passage and the tip reaches the fiber connecting portion.

After the tip of the seed thread reaches the fiber converging portion, the fiber bundle of the fiber converging portion along with the seed thread is drawn out from the thread drawing passage through the introduction passage by the action of the drawing roller.

Thereafter, the fiber bundle (thread) is moved from the introduction passage to the yarn passage.

The fiber bundle (thread) introduced into the thread passage is regulated to move to the introduction passage side by the action of the restricting means, and the spinning continues in the state passing through the thread passage.

The room 32 is provided with an opening through which the compressed air supply pipe 34 is connected, while passing through each of the injection port names 31 and the holes 33.

The compressed air supply pipe 34 is connected to a compressed air source (not shown), and a pressure regulator and a valve (not shown in the drawing) are provided in the meantime.

The ejector 29 is configured to generate negative pressure on the inlet side of the passage 30 while compressed air is injected from the injection hole 31.

The inner rotor 11 is formed with a part of its circumferential surface extending to the vicinity of the fiber focusing portion 6a of the outer rotor 6 and at the center of the side corresponding to the boss portion 18. The recessed part 35 into which the navel 27 is loosely fitted is formed.

The inner rotor 11 is formed such that the radius of the maximum outer diameter is larger than the radius of the inner surface of the open end terminal of the outer rotor 6.

In the maximum outer diameter portion of the inner rotor 11, a first passage part is located near the fiber focusing part 6a of the outer rotor 6, and a second passage part is opened on the circumferential surface of the concave part 35, respectively. 36 is formed such that the inner rotor 11 extends in the radial direction.

The shaft is fixed by screwing, gluing or pressing.

The unevenness | corrugation is formed so that it may extend along the extraction direction of the fiber bundle F, and is formed smaller than the diameter of the fiber bundle F, and larger than the diameter of a fiber.

In addition, as shown in FIG. 3, FIG. 4, etc., the introduction passage 38 which connects to the largest outer diameter part of the inner rotor 11 and runs continuously in the opening side of the outer rotor 6 is shown. It is formed to extend in the radial direction of the inner rotor (11).

The introduction passage 38 is formed such that the first terminal portion is opened to the circumferential surface of the concave portion 36 in the vicinity of the fiber focusing portion 6a, similarly to the actual passage 36.

As shown in FIG. 4 and the like, the introduction passage 38 is formed so that the wall surface 38a on the side corresponding to the actual passage 36 extends inclined toward the portion communicating with the actual passage 36 in succession.

The wall surface 36a on the side corresponding to the seal passage 36 and the introduction passage 38 is formed almost vertically, and the wall surface 36a is moved to the introduction passage 38 side of the fiber bundle F. It constitutes a regulatory means to regulate.

In addition, the cover plate 11a is fixed to the part in which the real passage 36 and the introduction passage 38 of the inner rotor 11 are formed.

Next, the operation of the apparatus configured as described above will be described.

In the radial operation, the driving belts 8 and 13 travel in the same direction, and the external rotor 6 and the internal rotor 11 are respectively in the same direction via the rotor shaft 7 and the shaft 10. Rotationally driven, the fiber bundle F is gradually detached from the fiber converging portion 6a and introduced into the thread passage 36.

The rotational speed of the inner rotor 11 is rotated at a speed slightly slower (slightly faster than the rotational speed of the outer rotor 6) than the removal speed of the fiber bundle F from the fiber converging portion 6a.

In addition, compressed air is supplied to the ejector 29 from the compressed air source via the compressed air supply pipe 34, and the draw passage 26 of the chamber on the upstream side (external rotor 6 side) is larger than the ejector 29. A negative action in the external rotor 6 causes the negative pressure to become negative again.

In this state, the released fibers, which have been released by the action of the comb hollow 21 and fed out into the outer rotor 6 from the fiber transport tow 22, slide and slide along the inner wall surface of the outer rotor 6, The fiber focusing portion 6a, which is the largest inner diameter portion, is focused.

The fiber bundle F focused on the fiber concentrating portion 6a is smoothly separated from the fiber concentrating portion 6a by a suction airflow directed to the thread passage 36 generated based on the negative pressure in the thread passage 36. And is introduced into the actual passage 36.

The fiber bundle F is twisted by the rotation of the inner rotor 11 along with the drawing of the yarn Y drawn through the thread pipe 28 by a drawing roller (not shown in the drawing). Is withdrawn).

The twist applied to the yarn Y and the fiber bundle F is transmitted upstream of the terminal portion 29a of the yarn pipe 29 as a starting point.

The fiber bundle F is introduced into the thread passage 36 in a state of being in contact with the twist propagation preventing portion 37 provided at the inlet of the thread passage 36.

As a result, the fiber bundle F has a fiber bundle F upstream than the position corresponding to the twist propagation prevention portion 37 where the thread and the fiber bundle which are pulled out while the rotation thereof is suppressed and begin to twist in the corresponding place. Propagation to is suppressed.

That is, the twist prevention is performed at the position facing the twist propagation prevention part 37.

Therefore, when the fiber bundle F starts to be twisted, tension is applied to the fiber and the fiber begins to be twisted in an elongated state, and the fiber is twisted straight, thereby increasing the strength of the thread and obtaining a good finish. Lose.

As described above, since the propagation of the twist upstream from the corresponding twist propagation prevention portion 37 of the fiber bundle F is prevented, the fiber bundle F immediately after being detached from the fiber bundle 6a has strength. Is weak.

However, since the inner rotor 11 is actively driven at a predetermined speed independently of the outer rotor 6, the force acting on the fiber bundle F at the time of detachment is stabilized, and the fiber bundle F is detached. Smelling is performed smoothly.

Since suction air flows toward the thread passage 36 by the action of the ejector 29, the removal and introduction of the fiber bundle F into the thread passage 36 are performed smoothly.

At the joint of the thread, in order to reduce the tension of the thread caught on the fiber bundle F, the rotational speed of the inner rotor 11 is made equal to the speed of detaching the fiber bundle F from the fiber bundle 6a. .

In addition, the supply of compressed air to the ejector 29 is stopped while the external rotor 6 and the internal rotor 11 are rotated.

As a result, the internal pressure of the external rotor 6 acts on the thread draw-out passage 26 and enters the seal passage 36 and the inlet passage 38 from the thread draw passage 26 via the concave portion 35. Air flow to the gas is generated.

Since the introduction passage 38 has a larger cross-sectional area than the actual passage 36, more air flows into the introduction passage 38 than the actual passage 36.

In this state, when the working chamber is inserted into the thread drawing passage 26 from the thread pipe 28, the seed chamber is introduced into the introduction passage 38 having a large air flow rate.

Then, the tip is smoothly introduced into the inlet by the action of the air flow and centrifugal force to reach the fiber focusing portion 6a.

Next, when the drawing roller (not shown) is driven forward and the seed thread is drawn out, the fiber bundle F focused on the fiber focusing portion 6a is wound around the terminal part of the seed chamber and separated from the fiber focusing portion 6a. It is withdrawn and withdrawn.

That is, as shown by the dashed line in FIG. 3 and the solid line in FIG. 4, the yarn Y is radiated in a state in which the thread Y is drawn out from the introduction passage 38 at the beginning.

Next, the rotation speed of the internal rotation 11 is changed to be slower than the removal speed of the fiber bundle F. As shown in FIG.

As a result, a force acts in the direction to move the seal Y in the introduction passage 38 to the seal passage 36 side, so that the seal Y moves to the seal passage 36 side along the wall surface 38a and the seal passage. It is introduced into 36.

The wall surface 36a on the introduction passage 38 side of the actual passage 36 is formed perpendicular to the rotation surface of the inner rotor 11, and furthermore, since the width of the actual passage 36 is narrow, the actual passage 36 is once. The seal Y does not escape from the seal passage 36.

Therefore, after that, as shown by a solid line in FIG. 3, the yarn Y is radiated in a state where it is drawn out from the yarn passage 36.

Example 2

Next, the second embodiment will be described with reference to Figs.

In this embodiment, the shape of the introduction passage 38 and the twist propagation preventing portion 37 formed in the inner rotor 11 and the configuration of the navel 27 are different from those in the above-described embodiment.

The seal passage 36 is formed in the center of the maximum outer diameter portion of the inner rotor 11, and the twist propagation prevention portion 37 is provided at each inlet portion of the fiber bundle F at the inlet portion moving direction. have.

The introduction passage 38 is integrally formed with the actual passage 36 in the same width through the inner passage 11 and the opening passage side of the inner rotor 11 and the outer rotor 6 in succession.

In other words, the actual passage 36 is narrower in width than the introduction passage 38 by the amount of the twist propagation preventing portion 37 provided at the inlet portion thereof.

9 and 10, the twist propagation prevention portion 37 is formed in a circumferential shape, so that the cross section of the side corresponding to the introduction passage 38 extends inclined toward the direction falling from the introduction passage 38. As shown in FIG. Formed.

The navel 27 has an axial direction of the inner rotor 11 in a state in which the cylindrical portion 27a is inserted through the housing 17 and the guide member 39 having a bottom surface fixed to the housing 17. It is supported to be movable according to.

Guide groove 39a is formed in guide member 39.

An opening is formed in the middle of the tube portion 27a through which the pipe pipes 28 are successively formed, and an engaging portion 27b penetrates the guide groove 39a through the guide groove 39a on the outer surface of the base terminal of the tube portion 17a. It protrudes in the direction crossing at right angles.

The guide groove 39a is formed in a shape that moves the navel 27 in the axial direction when the engaging portion 27b is rotated by a rotating solenoid not shown.

In the open-ended spinning machine of this embodiment, the navel 27 is disposed at a spinning position in which the tip thereof is coplanar with the fiber focusing portion 6a, as shown in FIG.

In this state, the fiber bundle F detached from the fiber converging portion 6a is pulled out of the thread drawing passage 26 while moving in the thread passage 36 while contacting the twist propagation preventing portion 37.

Thus, as in the above embodiment, the fiber bundle F is twisted in a stretched state by applying a tensioner to the fiber when it starts to twist, and the fiber is twisted straight so that the strength of the thread increases and the finish is good. Is obtained.

As shown in FIG. 8, when the thread is jointed, the navel 27 is disposed at a position where the tip thereof becomes the opening side of the outer rotor 6 rather than the tip of the twist propagation preventing portion 37.

In addition, the supply of compressed air to the ejector 29 is stopped while the external rotor 6 and the internal rotor 11 are rotated as in the above-described embodiment.

In this state, the seed chamber is inserted into the thread drawing passage 26 from the thread pipe 28.

The seed chamber is external rotor by the action of centrifugal force by the rotation of the above-mentioned flow and the internal rotor 11 flowing into the concave portion 35, the thread passage 36 and the introduction passage 38 from the thread draw passage 26. It moves toward the inner wall surface of (6).

Since the tip of the navel 27 is located on the opening side of the outer rotor 6 rather than the tip of the twist propagation prevention portion 37, the seed chamber moves into the introduction passage 38.

After the tip of the seed chamber reaches the inner wall surface from the outer rotor 6 from the fiber converging portion 68 on the opening side, the inner wall surface is slid to reach the fiber concentrating portion 6a.

Next, the seed thread is drawn out by the forward rotation driving of the drawing roller (not shown), and the bundled fiber bundle F of the fiber focusing portion 6a is wound around the terminal portion of the seed chamber and the fiber focusing portion 6a is attached. It is detached from and withdrawn by the seed chamber.

That is, as shown in FIG. 8 and FIG. 9, the yarn Y is radiated | emitted from the introduction passage 38 at the beginning of the joint of a yarn.

Next, the navel 27 is moved in the axial direction, and as shown in FIG. 6, the tip is disposed at a radial position that is coplanar with the fiber focusing portion 6a.

As shown in FIG. 10, with the movement of the navel 27, the yarn Y in the introduction passage 38 moves to the yarn passage 36 side.

And as shown in FIG. 6, when the movement of the navel 27 is completed, the fiber bundle F removed from the fiber concentrating part 6a contacts the twist propagation prevention part 37, and the inside of the thread path 36 is carried out. While moving, it is in a state of drawing out from the actual drawing passage 26.

In other words, in this embodiment, the navel 27 constitutes a restricting means for regulating the movement of the fiber bundle F introduced into the thread passage 36 toward the passage passage 38.

Example 3

Next, the third embodiment will be described with reference to Figs.

In this embodiment, the configuration of the twist propagation preventing unit 37 is different from those in the above embodiments, and the shape of the introduction passage 38 is basically the same as in the first embodiment.

At the distal end of the inner rotor 11, an accommodating concave portion 40 is formed at a position corresponding to the inlet of the thread passage 36 and opened on the housing 17 shaft and the fiber converging portion 6a. The housing 17 shaft of the 40 is closed by the cover plate 11a.

11 to 13, the concave concave portion 40 is formed in an expanded state on both sides of the thread passage 36, and the concave concave portion 40 is fitted with a thread passage 36 in a cylindrical shape. The contact members 41 and 42 are arranged one set.

The twisted wave prevention part 37 is comprised by the both contact members 41 and 42. As shown in FIG.

As shown in FIG. 14, the first contact member 41 is formed longer than the second contact member 42.

The first contact member 41 is immovably fixed to the inner rotor 11.

The pin 43 protrudes from the center of the second contact member 42 at an eccentric position, and the pin 43 is freely rotated in the support hole 44 formed in the inner rotor 11. Supported.

The center 01 of the second contact member 42 and the center 02 of the pin 43 are eccentric by the distance e.

The position of the pin 43 is positive when the center 01 of the second contact member 42, the center 02 of the pin 43, and the center of rotation of the inner rotor 11 are located in a straight line. The size of the space | interval x of the contact members 41 and 42 is set so that it may become smaller than the thickness of the fiber bundle of an inlet part.

Next, the operation of the apparatus configured as described above will be described.

In the radial operation, the fiber bundle F focused on the fiber connecting portion 6a is smoothly detached from the fiber connecting portion 6a in the same manner as in each of the long-term embodiments, and the inner rotor 11 is accompanied by the withdrawal of the yarn Y. It is drawn out as the yarn Y while being twisted by the rotation of.

The fiber bundle F is introduced into the thread passage 36 in contact with both contact members 41 and 42 provided at the inlet of the thread passage 36.

At the time of spinning in which fiber bundles exist between the two contact members 41 and 42, the second contact main 42 is the center of the second contact member 42 (01) and the center of the pin 43 (02). ) And the center of rotation of the internal rotor 11 are in a straight line.

As a result, the second contact member 42 is centered (01), centered (02), and inner rotor by centrifugal force acting on the second contact member (42) with the rotation of the inner rotor (11). A force is applied to rotate in the direction in which the center of rotation of (11) is in a straight line (clockwise in FIG. 13).

That is, during spinning, a force for always pushing the fiber bundle F toward the first contact member 41 acts on the second contact member 42.

Accordingly, the fiber bundle F moving into the thread passage 36 is in a state in which both sides of the fiber bundle F are pushed against the pressure contact members 42 and 42 at positions corresponding to the contact portions 41 and 42. .

As a result, the fiber bundle F has a fiber bundle upstream than the position corresponding to the two contact members 41 and 42 when the fiber bundle F is pulled out while its rotation is suppressed and starts to twist. Propagation to F) is suppressed.

That is, the twist prevention is made at a position corresponding to the two contact members 41, 42.

In addition, since the second contact member 42 is rotatable about the pin 43, even if the thickness of the fiber bundle f varies slightly, the second contact member 42 responds to the pin 43 accordingly. Rotation to the center does not act unreasonable force on the fiber bundle (F).

At the time of the joint of the yarn, the seed yarn is first introduced into the introduction passage 38 in the same state as in the first embodiment described above, and the yarn Y is drawn out from the introduction passage 38 as indicated by the broken line in FIG. Is emitted from

Next, the rotational speed of the inner rotor 11 is changed to be later than the moving speed of the removing point.

As a result, a force acts in the direction which moves the seal Y in the introduction passage 38 to the seal passage 36 side, and the seal Y moves to the seal passage 36 side along the wall surface 38a.

Since the plane passing through the front end of the navel 27 and the fiber focusing portion 6a is in a state passing substantially through the center in the longitudinal direction of the first contact member 41, as shown by the solid line in FIG. Y) is introduced at a position to be fitted to the two contact members 41 and 42 in the seal passage 36.

After that, as shown by the solid line in FIG. 14, the yarn Y is radiated in a state of being drawn out from the yarn passage 36.

Example 4

Next, the fourth embodiment will be described with reference to FIGS. 15 to 21. FIG.

In this embodiment, the position where the fiber bundle F (thread Y) passes between the fiber bundle 6a and the fiber 27 is introduced into the navel 27 during normal spinning is the fiber bundle 6a. The difference from the virtual plane in which is present is significantly different from each of the above-described embodiments.

As shown in Fig. 15A, the outer rotor 6 is provided with a fiber concentrating portion 6a, and a receiving portion 6b having a diameter larger than the fiber condensing portion 6a is formed on the side opposite to the opening opening side. .

The inner rotor 11 is a shape in which both sides of the disc are symmetrically cut, and the maximum outer diameter thereof is larger than the diameter of the fiber concentrating part 6a, and is fixed to the shaft 10 while being accommodated in the accommodating part 6b. It is.

The outer rotor 11 has a concave portion 45 which is continuous to the concave portion 35 into which the navel 27 is fitted loosely and has a width of almost half of the inner rotor 11. It is formed in the state reaching the position of the 1st terminal part of the vicinity.

The recessed part 45 is formed in the back side of the rotation direction (arrow direction of FIG. 16) at the time of the spinning of the internal rotor 11. As shown in FIG.

The navel 27 is arranged so that its tip is located on the bottom side side (opposite side of the opening side) of the outer rotor 6 rather than the virtual plane including the fiber focusing portion 6a.

In addition, the fiber concentrating part 6a is shown with the dashed line in FIG.

The concave portion 45 serves as a thread passage for introducing the seed thread and a thread passage for guiding the fiber bundle F drawn out from the fiber focusing portion 6a to the position facing the thread draw passage 26 during normal spinning. Do this.

The diameter of the largest inner diameter of the concave portion 45 is formed larger than the diameter of the fiber converging portion 6a, and the shape of the concave portion 45 near the maximum outer diameter portion of the inner rotor 11 has the shape of the opening end edge. It is formed in the shape which cut out toward the 1st terminal part side of the internal rotor 11 so that the diameter of the bottom face part side may become larger than the diameter.

In the concave portion 45, the engaging pin 46 as a restricting means intersects at right angles to the longitudinal direction of the inner rotor 11 at the first terminal side of the inner rotor 11 and at the same time the concave portion 45 Protrude in a state where there is a gap between the first terminal side and the open end terminal.

The engaging pin 46 has a groove 46a for defining the withdrawal position of the fiber bundle F at the base terminal side, and at the same time, the side corresponding to the first terminal side of the concave portion 45 of the tip end thereof is the base terminal. It is cut inclined toward the negative side.

Moreover, the guide inclined surface 45a as a guide surface is formed in the side which opposes the engagement pin 46 at the side of the 1st terminal part of the recessed part 45. As shown in FIG.

Next, the operation of the device configured as described above will be described.

In the radial operation, as shown in FIG. 15A, the fiber bundle F focused on the fiber converging portion 6a is connected to the inner rotor along the wall surface of the external rotor 6 from the fiber converging portion 6a. It is withdrawn to 11) side.

Then, it starts to be wound on the engagement pin 46, the drawing direction is changed, and is introduced into the navel 27 and is drawn out as the thread Y while being twisted by the rotation of the internal rotor 11.

The fiber bundle F is fastened because the gap between the engaging pin 46 and the wall 45b of the concave portion 45 is narrow and the fiber bundle F is drawn out while being wound on the engaging pin 46. At (46) and the wound place, the rotation is suppressed.

That is, propagation to the yarn Y and the fiber bundle F which are pulled out while being twisted is suppressed.

In each of the above embodiments, the fiber bundle F is pulled directly from the fiber converging portion 6a toward the center of the outer rotor 6 and introduced into the inlet portion of the actual passage 36 of the inner rotor 11.

Therefore, the fiber bundle F is pulled out in a state where the raw force acting by the rotation of the external rotor 6 is applied as a force opposed to the withdrawal of the fiber bundle F being pulled out.

That is, a large tension is applied to the fiber bundle (F) is not twisted.

Since the winsimse force is proportional to the square of each speed, when the outer rotor 6 rotates at a high speed, the external rotor (directly from the fiber converging portion 6a) is opposed to the fiber bundle F, which is not twisted, against the centrifugal force. It becomes difficult to draw out toward the center side of 6).

However, in this embodiment, the fiber bundle F focused on the fiber converging portion 6a is drawn out to the inner rotor 11 side along the wall surface of the outer rotor 6, and at the position of the engaging pin 46. It is drawn out toward the center side of the external rotor 6.

The fiber bundle F slides on the wall surfaces of the outer rotor 6 and the inner rotor 11 to a position corresponding to the engagement pin 46 in a state where the twist is not applied.

Therefore, the tension required to move the fiber bundle F needs to have a magnitude that can withstand the component force in the wall direction of the centrifugal force and the frictional resistance between the fiber bundle F and the wall surface.

As shown in Fig. 15 (b), the centrifugal force (f) acting on the fiber bundle (F), the friction coefficient between the fiber bundle (F) and the wall surface (μ), and the vertical direction and centrifugal force on the wall surface act When the angle formed with the direction is (θ), the resistance force N1 acting on the fiber bundle F and the force N2 acting in parallel with the wall surface are expressed by the following equation.

N1 = f × cosθ, N2 = f × sinθ

Therefore, the tension T necessary for moving the fiber bundle F is given by the following equation.

T = f × sinθ + μ × cosθ

Coefficient of friction (μ) is a tension (T) because of the size of ^10-1, less than cosθ, sinθ 1 is a small value compared with the centrifugal force (f), the twisting load on the fiber bundle (F) does not need to geolryeok fiber It moves smoothly from the focusing part 6a to the position corresponding to the engagement pin 46.

Then, at the position where the pullout direction of the fiber bundle F is directed from the engaging pin 46 to the side opposite to the direction of the centrifugal force toward the navel 27, the fiber bundle F is twisted so that the external rotor Even when 6 is rotated at a high speed, the fiber bundle F is taken out smoothly.

Next, the operation | movement at the time of the joint of a thread is mentioned.

At the time of jointing of the thread, the rotational speed of the inner rotor 11 is the same as the speed of detaching the fiber bundle F from the fiber converging portion 6a, and is slightly faster than the rotational speed of the outer rotor 6.

Then, the supply of compressed air to the ejector 29 is stopped while the external rotor 6 and the internal rotor 11 are rotationally driven.

As a result, the negative pressure in the external rotor 6 acts on the thread drawout passage 26 and air flows from the thread drawout passage 26 into the external rotor 6.

In this state, when the seed chamber is inserted into the thread drawing passage 26 from the thread pipe 28, the seed chamber reaches the fiber converging portion 6a by the action of air flow and centrifugal force.

Next, when the drawing roller (not shown) is driven forward and the seed thread is drawn out, the fiber bundle F focused on the fiber focusing part 6a is wound around the terminal part of the seed room and separated from the fiber focusing part 6a. It is lost and withdrawn.

And as shown in FIG. 17 (a) and FIG. 19, in the initial stage of the joint of the thread, the fiber bundle F is in the state in which the yarn Y is not engaged with the engagement pin 46. It radiates in the state which introduces into the navel 27 via the recessed part 45 of (circle).

Next, the rotation speed of the inner rotor 11 and the detachment speed of the fiber bundle F are changed to be slower.

As a result, the position of the peeling point P of the fiber bundle F is relatively moved from the position of FIG. 17 (a) to the front side in the rotational direction of the inner rotor 11, and the fiber bundle F (the yarn ( Y)] also move in the same direction.

Since the centrifugal force acts on the fiber bundle F, the fiber bundle F drawn out from the fiber focusing portion 6a along the walls of the external rotor 6 and the internal rotor 11 is the fiber bundle F. Even when [Y (Y)] moves, it moves while sliding on the wall surface.

And through the state of FIG. 17 (b) and FIG. 20, it moves between the engagement pin 46 and the wall surface 45b of the recessed part 45, and as shown in FIG. 18 and FIG. 21, the engagement pin It is in a state of being engaged with (46).

Thereafter, it is radiated in the state shown in FIGS. 18 and 21 to be drawn out while being engaged in the groove 46a by the engagement pin 46.

Moreover, in FIG. 17 and FIG. 18, the fiber concentrating part 6a is shown with the dashed line.

That is, the concave portion 45 is a pull-out passage for guiding the fiber yarn F drawn out from the fiber converging portion 6a to the position facing the thread take-out passage 26 at the time of introduction of the seed yarn and normal spinning. It serves as.

In addition, since the shape of the concave portion 45 on the side of the first terminal of the inner rotor 11 is formed so that the diameter of the bottom portion is larger than the diameter of the opening end edge, the fiber bundle F is connected at the time of thread joining. When centrifugal force moves to the normal spinning position, the centrifugal force promotes the action of introducing the fiber bundle F between the engaging pin 46 and the wall surface 45b.

Example 5

Next, the fifth embodiment will be described with reference to FIGS. 22 and 23. FIG.

In this embodiment, the configuration of the restricting means is different from that of the fourth embodiment, and the other configurations are the same.

In this embodiment, the front wall side of the inner rotor 11 rotates in a state in which the partition wall 47 that partitions a part of the drawing chamber passage from the outer rotor 6 side space covers a part of the opening of the recess 45. Is formed to protrude from the wall surface of the.

Between the wall surface 45 and the 1st terminal part of the partition wall 47, the space | interval which is slightly narrower than the diameter of the thread | spinning yarn is formed.

Further, a semi-circular engaging portion 47a as a restricting means is formed on the first terminal side of the inner rotor 11 at the first terminal portion of the partition wall 47.

In the apparatus of this embodiment, at the time of normal spinning, the fiber bundle F focused on the fiber focusing portion 6a is moved from the fiber focusing portion 6a to the inner rotor 11 along the wall surface of the external rotor 6. Withdrawn.

Then, the fiber bundle F is introduced between the wall surface 45b and the surface of the engaging portion 47a, and at the same time, the withdrawal direction is changed in the engaging portion 47a and introduced into the navel 27, It is drawn out as the yarn Y while being twisted by the rotation of the internal rotor 11.

Since the space | interval of the engagement part 7a and the wall surface 45b is narrow, the fiber bundle F is prevented from rotating in the said location.

That is, the rotation of the yarn Y and the fiber bundle F which are pulled out by being twisted is propagated to the fiber bundle F upstream than the position corresponding to the engagement part 7a.

Therefore, also in this embodiment, the same effect as that of the fourth embodiment is achieved.

In addition, joining of a thread is performed in the same procedure as the above-mentioned fourth embodiment.

Example 6

Next, the sixth embodiment will be described with reference to FIGS. 24 and 25. FIG.

This embodiment is different from the fourth embodiment in the configuration of the restricting means, and the other configuration is the same.

That is, instead of protruding the engaging pin 46 at a predetermined position, the pin is rotatable and provided so that the center of the pin and the center of rotation of the pin are eccentric.

The engaging pin 48 has a tip end formed in a truncated cone shape, and a shaft 49 protrudes from the center of the base end at an eccentric position.

However, the bearing 49 accommodated in the receiving hole formed in the wall surface of the concave portion 45 (the shaft 49 is rotatably supported because none of them is shown in the drawing).

The engaging pin 48 is formed with a groove 48a toward the base terminal side.

The position of the shaft 49 is a centrifugal force acting on the engaging pin 48 at the time of rotation of the inner rotor 11 while the engaging pin 48 is in contact with the wall surface 45b of the concave portion 45. The dowel pin 48 is set to apply a force to the fiber bundle F in the direction of withdrawal and in the reverse direction (counterclockwise direction in FIG. 25).

In this embodiment, the fiber bundle F is drawn out via the navel 27 in a state of engaging with the groove 48a of the engagement pin 48, as in the fourth embodiment during normal spinning.

The center of the engagement pin 48 and the center of rotation thereof, that is, the center of the shaft 49 are eccentric, and as shown in FIG. 25, the center of the shaft 49 is the center of the engagement pin 48 during radiation. It is located in the opening side of the recessed part 45 more.

As a result, the centrifugal force acting on the engagement pin 48 at the time of rotation of the inner rotor 11 acts to rotate the engagement pin 48 in the counterclockwise direction of FIG. 25 about the axis 49.

That is, during spinning, the force for pushing the fiber bundle F to the wall surface 45b always acts on the engagement pin 48, and the fiber bundle F is prevented from being twisted at this point.

In addition, since the engagement pin 48 is rotatable about the axis 49, even if the thickness of the fiber bundle F varies slightly, the engagement pin 48 is rotated about the axis 49 correspondingly to the fiber. No excessive force is acting on the bundle (F).

In addition, unlike the fourth embodiment, it is not necessary to adjust the distance between the engaging pin 48 and the wall surface 45b in response to a change in the thickness of the spinning chamber accompanied by a change in the spinning condition.

Example 7

Next, the seventh embodiment will be described with reference to FIGS. 26 to 28. FIG.

This embodiment is different from the sixth embodiment in the configuration of the restricting means, and the other configuration is the same.

That is, instead of installing the engagement pin 48 rotatably, the restricting means is comprised by the support shaft 52 and the cylinder 53 loosely fitted to the support shaft 52.

As shown in FIG. 26, the support shaft 52 protrudes from the wall surface of the recessed part 45, and the tip-shaped guide part 52a of the cone shape is formed in the front-end | tip.

A groove 53a is formed in the outer circumferential surface of the cylinder 53.

As shown in FIG. 27, the cylinder 53 is able to contact the outer peripheral surface with the wall surface 45b in the state in which the inner peripheral surface is engaged with the support shaft 52. As shown in FIG.

In the structure of this embodiment, if the fiber bundle F does not exist at the time of the cylinder 53 and the wall surface 45b in the state in which the inner rotor 11 was rotated, the cylinder 53 will be closed by the action of centrifugal force. It abuts against the wall surface 45b and is maintained in contact with the support shaft 52.

At the time of spinning, the fiber bundle F is in the state of FIG. 28 passing between the cylinder 53 and the wall surface 45b, and the fiber bundle F is pushed to the wall surface 45b by the cylinder 53. Twisting is prevented.

In this embodiment, since the cylinder 53 is free to move compared with the engagement pin 48 of the sixth embodiment, it is easy to follow the change in the thickness of the fiber bundle F. FIG.

Example 8

Next, an eighth embodiment will be described with reference to FIGS. 29 to 34. FIG.

This embodiment is different from the sixth embodiment in the configuration of the restricting means, and the other configuration is the same.

The support lever 54 is rotatably arranged in the recess 45.

A support shaft 55 protrudes from the support lever 54, and a support shaft 55 is rotatably supported by a bearing installed on the wall of the recess 45, and a pillar 56 is provided at the tip of the support lever 54. ) Is protruding.

As shown in Fig. 31 (a), the center of gravity G of the support lever 54 is located on the pin 56 side than the center of rotation 03 thereof.

As shown in Fig. 31 (a), the support lever 54 is disposed at a position where the center of gravity G and the center of rotation 03 are positioned on a plane yarn parallel to the plane including the fiber focusing portion 6a. The position of the support shaft 55 is set so that the space | interval (DELTA) t exists between the wall surface 45b and the pin 56 in a state.

The interval Δt is set smaller than the thickness of the yarn to be spun.

And with the rotation of the support lever 54, the pin 56 becomes accessible to the wall surface 45b.

As shown in FIG. 32 and FIG. 33, the support lever 54 is rotated in the extraction direction of the fiber bundle F by the pulling output of the fiber bundle F during spinning, and the pin 56 and the wall surface 45b are rotated. ) Is enlarged.

While the inner rotor 11 is rotating, the centrifugal force acts to place the support lever 54 at the position (lifting position) of FIGS. 29 to 31, and the pin 56 is subjected to the fiber bundle F by the force. ) Is compressed to the wall surface 45b.

This compression force is determined by the rotation angle (θ1) from the reference position shown in FIG. 31 (b) and the distance between the center of gravity (G) and the rotation center (03) when the number of revolutions of the internal rotor 11 is constant. ) And the distance between the center of the pin 56.

The distance between the center of gravity G and the center of rotation 03 and the distance between the center of rotation 103 and the center of the pin 56 are determined by the shape of the support lever 54.

By appropriately setting the shape of the support lever 54, the fiber bundle F can be spun in a state in which a desired extrusion force is applied.

In addition, it is not necessary to set the interval Δt in accordance with the thickness of the yarn to be discharged by setting the interval Δt = 0.

In the configuration of this embodiment, the compression force acting on the fiber bundle F is easier to adjust than in the sixth and seventh embodiments.

Example 9

Next, the ninth embodiment will be described with reference to FIGS. 35 to 38. FIG.

In this embodiment, the fiber bundle F is pulled directly from the fiber connecting portion 6a to the center side of the external rotor 6 at the outside of the inner rotor 11 at the time of thread joining, and then inside the inner rotor 11. The change in the state passing through is different from each of the above-described embodiments.

37 and 38, the inner rotor 11 is formed in a shape in which the width of the first terminal portion is narrow as in the case of the first to third embodiments, and is continuous to the concave portion 35. As shown in FIG. It is formed in the state which is open to the opening side of the actual passage 57 and the external rotor 6.

At the position corresponding to the first terminal portion of the thread passage 57, the receiving recess 58 is formed to expand to both sides of the thread passage 57, and the receiving recess 58 has a set of rollers 59, ( 60 is rotatably arranged.

The rollers 59 and 60 are arranged in parallel with each other at intervals narrower than the thickness of the radiation chamber in a state inclined such that the tip side thereof faces the inner rotor 11.

The roller 59 provided on the front side in the rotational direction of the inner rotor 11 is formed to have a length protruding to the outside of the receiving recess 58.

The roller 60 installed on the rear side in the rotational direction of the inner rotor 11 is formed to have a length that does not protrude outside the accommodating concave portion 58, and is formed in a conical shape at the tip thereof, and has a positive roller 59, 60 is an anti-twist means.

Like the second embodiment, the navel 27 is configured to be movable along the axial direction of the internal rotor 11 by the operation of a rotating solenoid (not shown).

In the normal spinning, the navel 27 is disposed at the radial position where the tip thereof enters into the concave portion 35 as shown in FIGS. 35 and 38.

In this state, the fiber bundle F detached from the fiber converging portion 6a is drawn out to the inner rotor 11 side along the wall surface of the outer rotor 6 as in the fourth embodiment described above.

And it is wound by the roller 59, the extraction direction is changed and introduced into the navel 27, and is drawn out as the yarn Y while being twisted by the rotation of the inner rotor 11.

Since the distance between both the rollers 59 and 60 is narrower than the thickness of a spinning chamber, the fiber bundle F is prevented from rotating in the said location.

That is, the propagation of the yarn Y and the fiber bundle F which are pulled out by twisting is propagated to the fiber bundle F upstream than the position corresponding to the 59 and 60 in a positive manner.

As shown in FIGS. 36 and 37, when the thread is jointed, the navel 27 is separated from the concave portion 35, and the tip is disposed at a position where the tip thereof is coplanar with the fiber connecting portion 6a.

As in the fourth to eighth embodiments, the supply of the compressed air to the ejector 29 is stopped while the external rotor 6 and the internal rotor 11 are rotationally driven.

In this state, the seed chamber is inserted into the thread drawing passage 26 from the thread pipe 28.

The seed chamber moves toward the inner wall surface of the outer rotor 6 by the action of the air flow flowing into the outer rotor 6 from the thread draw passage 26.

The tip of the seed chamber reaches the inner wall surface from the fiber converging portion 6a on the opening side of the outer rotor 6, and then slides the inner wall surface to reach the fiber connecting portion 6a.

Next, the seed thread is drawn out by the forward rotation drive of the drawing roller not shown in the drawing, and the fiber bundle F focused on the fiber focusing portion 6a is wound around the terminal part of the seed chamber, and the fiber focusing portion 6a is provided. It is separated from and drawn out with the seed chamber.

As shown in FIG. 36 and FIG. 37, in the initial stage of the joint of the yarn, the yarn Y is radiated in a state of being drawn out from the navel 27 without passing through the internal rotor 11.

Next, the navel 27 is moved in the axial direction, and as shown in FIGS. 35 and 38, the front end is loosely fitted to the concave portion 35 and the fiber converging portion 6a is present. It is disposed in the radial position opposite to the opening terminal of the outer rotor (6).

And with the movement of the navel 27, the yarn Y moves to the thread passage 57 side.

35 and 38, when the movement of the navel 27 is completed, the fiber bundle F detached from the fiber converging portion 6a is in contact with the rollers 59 and 60 while passing through the thread passage. It moves to 57 and is withdrawn from the real draw path 26.

That is, in this embodiment, the navel 27 constitutes a restricting means for regulating the movement of the fiber bundle F introduced into the thread passage 57.

When the navel 27 is disposed at the radial position that is loosely fitted to the concave portion 35, and the rotational speed of the inner rotor 11 is later than that of the fiber bundle F, the fiber bundle F is detached. The point moves relative to the rotational direction front side of the inner rotor 11.

Even when the thread Y is in the position deviated from the thread passage 57 when the navel 27 is moved to the radial position, the thread Y moves to the position corresponding to the thread passage 57 by this operation. do.

Then, it is engaged with the roller 59 and is introduced between the rollers 59 and 60.

Example 10

Next, the tenth embodiment will be described with reference to FIG.

In this embodiment, the wall surface 45b of the concave portion 45 formed in the inner rotor 11 is formed substantially parallel to the axial direction of the inner rotor 11 and the diameter up to the wall surface 45b is fiber. The point formed substantially the same as the diameter of the focusing part 6a differs from the above-mentioned fourth to eighth embodiments.

In the apparatus shown in FIG. 39 (a), the inclination of the wall surface of the external rotor 6 extending from the fiber focusing part 6a toward the receiving part 6b side is smaller than in the above-described embodiment, and from the fiber focusing part 6a. The fiber bundle F which is drawn out and moves the wall surface 45b of the outer rotor 6 and the wall surface 45b of the inner rotor 11 is pulled out almost horizontally toward the engagement pin 46.

In the apparatus shown in FIG. 39 (b), the wall surface of the external rotor 6 extending from the fiber connecting portion 6a toward the receiving portion 6b side is formed substantially parallel to the axial direction of the external rotor 6. have.

The wall surface 45b of the inner rotor 11 is also formed on the extension line of the wall surface of the outer rotor 6.

In either case, the tension applied to the fiber bundle F when the fiber bundle F moves to the position corresponding to the engagement pin 46 causes the fiber bundle F to be directly externally rotated from the fiber focusing portion 6a. It is less compared with the case where it draws out to the central axis of (6).

Example 11

Next, the eleventh embodiment will be described with reference to FIG.

This embodiment differs from the tenth embodiment in that the diameter up to the restricting means for preventing the kink acting on the inner rotor is smaller than the diameter of the fiber concentrating portion 6a.

In the apparatus shown in Fig. 40 (a), the wall surface of the external rotor 6 extending from the fiber converging portion 6a toward the receiving portion 6b side is formed to extend inward.

The wall surface 45b is formed to extend substantially parallel to the axial direction of the inner rotor 11 from a position corresponding to the opening end edge of the accommodating portion 6b.

In the apparatus shown in FIG. 40 (b), the wall surface of the outer rotor 6 extending from the fiber converging portion 6a toward the receiving portion 6b side is formed substantially parallel to the axial direction of the outer rotor 6, The wall surface 45b of the inner rotor 11 is formed to extend inward.

Also in this embodiment, the tension applied to the fiber bundle F while the fiber bundle F moves to the position corresponding to the engagement pin 46 is such that the fiber bundle F is directly moved from the fiber bundle 6a. It is less compared with the case where it draws out to the center side of the external rotor 6.

In addition, in this embodiment, since the position of the engaging pin 46 is located inward of the fiber collecting section 6a, the maximum outer diameter of the inner rotor 11 is about the same size as the diameter of the fiber focusing section 6a. You can do

Therefore, the outer diameter of the outer rotor 6 can be of the same size as that of the first to third embodiments in which the fiber bundle F is pulled directly from the fiber converging portion 6a to the center side of the outer rotor 6. have.

In addition, this invention is not limited to each above-mentioned embodiment, For example, in the 2nd Example, as shown in FIG. 41, the introduction passage 38 is formed so that the opposite side to the actual passage 36 may be opened. You may also

Further, in the third embodiment, even if the tip side circumferential surface of the first contact member 41 is formed into a coarse surface, or as shown in FIG. 42, the tip side of the second contact member 42 is formed in a circumferential shape, do.

In such a configuration, the yarn Y introduced into the thread passage 36 from the introduction passage 38 at the time of jointing of the thread is easily introduced between the both contact members 41 and 42.

In the fourth embodiment, as the engaging pin 46, as shown in FIG. 43, a plurality of root bodies 46b formed on the circumferential surface in the circumferential direction may be used.

In addition, as the engaging pin 46 used in the sixth embodiment or the cylinder 53 used in the seventh embodiment, grooves 48a and 53a are formed in the circumferential surface as shown in FIG. 44 or FIG. You may use the thing which was not formed.

Even without the grooves 48a and 53a, there is no problem in the regulation function and the anti-twist function.

However, the grooves 48a and 53a have a constant engagement position between the fiber bundle F and the engagement pin 46 or the cylinder 53 in the usual manner, and the radiation stability is improved.

In the fifth embodiment, a curved plate spring may be attached to the partition wall 47 instead of the engaging portion 47a.

In the case of using the plate spring, an excessive compression force on the fiber bundle F is prevented from acting as the plate spring is bent when the thickness of the spun yarn changes.

In the first to third embodiments, the twist propagation prevention unit may be omitted.

Moreover, you may connect other suction means other than an ejector to a seal pipe as a sub arm generating apparatus.

Again, the ejector 29 is not necessarily required, and the ejector 29 may be omitted.

As described in detail above, according to the present invention, the tip of the seed chamber can be reliably reached to the fiber converging portion of the external rotor during thread joining, and the thread can be easily introduced into the thread passage formed in the internal rotor. This negative success rate is improved.

In addition, in the invention described in claim 3, the force required to detach the fiber bundle from the fiber concentrating part against the centrifugal force caused by the rotation of the external rotor is reduced, and even when the rotor and the internal rotor rotate at high speed, It is possible to withdraw the bundle stably.
