Abstract

PROBLEM TO BE SOLVED: To improve a yield rate of a filament by preventing a winding bobbin from colliding against a winding end layer of the filament, after its winding finishing end passes through a notch opening of an end cover. SOLUTION: After an end cover 24 is covered on a fully wound winding bobbin, before a winding finishing end 1a of a filament 1 is guided in a notch opening 24a of the end cover 24, a bobbin cover 40, overlapping with an inner side of the end cover 24, is moved so as to cover a winding bobbin 12. The winding end 1a of the filament 1, in an outer side of the bobbin cover 40, is drawn in while meandering in the end cover 24, but this meander part, in the case of passing through a clearance between a brim 12a of the winding bobbin 12 and the bobbin cover 40, collides against an end part 40a of the bobbin cover 40, energy tending to collide toward a surface of a filament unit winding layer 1A on the winding bobbin 12 is reduced.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of winding various filaments, such as optical fibers and electric wires, sequentially on a winding bobbin on a plurality of winding portions to continuously wind the filaments. And an improvement of an apparatus used in this method.

[0002]

2. Description of the Related Art A plurality of (usually two) windings as shown in FIGS. 9A and 9B are used to continuously wind a thin wire having a small diameter such as an optical fiber. Sections 10 and 10 'are used, and the filament 1 is sequentially wound around these winding sections 10 and 10' and continuously wound up. One winding unit 10
After the filament 1 is fully wound on the upper winding bobbin 12, the filament shift means 30 is moved from the dotted line position in FIG. The striatum 1 is wound around the bobbin 12 '. In this winding method, the filament 1 continuous with the filament winding layer 1A on the winding bobbin 12 on the full winding side is wound on the winding bobbin 1 on the next winding portion 10 '.
The winding start end is fixed to the winding bobbin 12 'on the next winding section 10' by hooking on the catching claw 28'a on the striated body capturing member 28 'of 2', and the winding bobbin 12 on the full winding side is fixed.
The filament 1 is separated from the upper filament 1 and is wound from the winding bobbin 12 on the full winding side to the winding bobbin 12 'on the next winding portion 10'.

[0003] In this case, the winding end 1a of the filament 1 formed by being separated from the filament 1 wound on the winding bobbin 12 'on the next winding portion 10' is on the full winding side. Before winding onto the empty winding bobbin 12 ′ on the next winding section 10 ′, the winding bobbin 12 on the full winding side is partially covered in order to prevent the The terminal cover 24 is moved to receive the winding end 1a of the striatum 1 (JP-B-62-25053, JP-B-62-27).
888, Japanese Patent Publication No. 62-132691, and Japanese Patent Application No. 6-170458).

[0004] The terminal cover 24 used in these prior arts has a cutout opening 24a in a part thereof, and a wire continuous with the striated winding layer 1A on the winding bobbin 12 on the full winding side. The strip portion is guided to the winding bobbin 12 'on the next winding portion 10' through the cutout opening 24a, and the filament capturing member of the winding bobbin 12 'on the next winding portion 10'. At the same time, the striated winding portion 1A on the winding bobbin 12 on the full winding side is cut off by being caught by the catching claw 28'a on the winding bobbin 12 and cut off from the captured portion. The winding end end 1a is formed with the notch opening 24 of the terminal cover 24 as the winding bobbin 12 rotates.
After passing through a, it is wound on the winding bobbin 12 on the full winding side. As shown in FIG. 9, in the invention of Japanese Patent Application No. 6-170458, when the filament 1 is cut off between the winding portions 10 and 10 ', the winding bobbin 12 on the full winding side is closed. In order to prevent the tension at the time of cutting off from affecting the striated body winding layer 1A, a striated body holding means 34 in the form of a pinch roll for sandwiching the striated body 1 is provided.

As shown in FIGS. 10 and 11, the terminal cover 24 has a spiral guide passage 25 on the inner surface thereof, and the winding end 1a of the filament 1 extends along the spiral guide passage 25. The winding end 1a of the winding bobbin 12 is guided toward one flange 12a of the winding bobbin 12 so as to prevent the winding end 1a from unraveling on the striatum winding layer 1A on the winding bobbin 12 (for example, Japanese Patent Application No. Hei 7 (1994) -197572). No. 167163 (see FIGS. 2 and 3). The spiral guide passage 25 is provided on the winding bobbin 12 on the full winding side.
In order to prevent the end-of-winding end 1a that has been wound into the winding-up bobbin 12 on the full winding side from jumping out of the cut-out opening 24a of the terminal cover 24 due to rotation before the stop, the end-of-winding end 1a is cut out of the opening 24a. It is formed so as to be guided to a position out of the way.

As described above, the terminal cover 24 is fully wound along the inner peripheral surface of the terminal cover 24 even if the winding end 1a of the filament 1 on the winding bobbin 12 on the full winding side receives centrifugal force. It has a function of rotating together with the winding bobbin 12 on the side and preventing the winding layer 1A of the filament 1 wound on the winding bobbin 12 from being damaged.

In this winding method, the winding end 1a of the filament 1 is guided into the terminal cover 24 as shown in FIGS. First, as shown in FIG. 12, after the winding end 1a of the filament 1 has passed through the filament holding means 34 and the guide roll 35, it will be guided into the inside through the cutout opening 24a of the terminal cover 24. However, as shown in FIG. 13, the winding end 1a collides with the lower edge of the notch opening 24a to form a bundle 1b. Then, as shown in FIG. be introduced.

As the winding speed of the filament 1 increases and the linear speed increases, the bundle 1 at the winding end 1a of the filament 1
When the momentum b is entangled through the notch opening 24a of the terminal cover 24, as shown in FIG. 14, the bundle 1b including the winding end 1a is less than the force toward the inner wall of the terminal cover 24 due to the centrifugal force. The force of the striated body 1 on the winding bobbin 12 on the full winding side toward the surface of the striated winding layer 1A is stronger, and the winding end 1a is the line on the fully winding bobbin 12. There is a possibility that the wire striking the surface of the winding layer 1A of the striated body 1 may damage the striated body. After that, the bundle 1b of the winding end 1a of the filament 1 is, as shown in FIG.
While being loosened by this collision, it is rebounded to the inner peripheral surface of the terminal cover 24, and thereafter guided by the spiral guide passage 25.

As described above, the applicant of the present invention has found that the winding end 1a of the filament 1 is the filament winding layer 1A on the winding bobbin 12.
FIG. 16A and FIG.
As shown in FIG. 6 (B), it is proposed to narrow the notch opening 24a of the terminal cover 24 as indicated by reference numeral 60 immediately before the end-of-winding end 1a of the striated body 1 is introduced (Japanese Patent Application No. Hei. 7-167163).

As described above, when the notch opening 24a is narrowed immediately before the winding end 1a of the filament 1 is introduced into the notch 24a of the terminal cover 24, the winding end 1a of the filament 1 is There is no bundling, and the force at which the winding end 1a tends to advance toward the striated winding layer 1A on the winding bobbin 12 is weakened. Therefore, the centrifugal force due to the rotation of the winding bobbin 12 is reduced. The end-of-winding end 1a does not collide with the filament winding layer 1A on the winding bobbin 12 by overcoming the force that tends to progress toward the filament winding layer 1A. Will not hurt.

In this prior art, in order to narrow the notch opening 24a of the terminal cover 24, the notch opening 24 is displaced along the peripheral wall of the terminal cover 24 as shown in FIG.
a, two arc-shaped movable lids 62 forming a throttle passage 60 through which the winding end 1a of the filament 1 passes partially by closing
64, and lid driving means (not shown) for driving the movable lids 62 and 64 to open and close.

However, the throttle passage 60 has a winding end 1a.
It is required that the movable lids 62 and 64 be provided with a large stroke length of arc movement, since the movable lids 62 and 64 are required to have a length necessary to attenuate the rampage of the moving parts. Since a complicated link mechanism for driving the movable lids 62 and 64 to move in an arc is required, there is a disadvantage that the structure is complicated as a whole and the equipment is expensive. still,
The aperture passage 60 may be formed by one movable lid. However, since the aperture passage 60 is formed between the movable cover and the peripheral wall of the terminal cover 24, the stroke of the movable lid is required to obtain the aperture passage 60 having a predetermined length. Has the disadvantage that the

[0013]

One problem that the present invention seeks to solve is that without requiring a complicated structure,
The winding of the striatum that can be wound without the end of winding of the striatum falling into the terminal cover and damaging the striatum winding layer on the winding bobbin. It is to provide a collecting method.

Another problem to be solved by the present invention is that the end of winding of the striatum does not unravel in the terminal cover,
An object of the present invention is to provide a winding device for a striated body that can take up the striated body without damaging the striated winding layer on the winding bobbin and does not complicate the structure. .

A second object of the present invention is to provide a winding bobbin in which a striated body is fully wound on one of a plurality of winding sections from an empty winding bobbin on the other winding section. When the striated body is shifted and the striated body is continuously wound, the terminal cover is put on the winding bobbin on the full winding side, and the winding end of the striated body is passed through the notch opening of the terminal cover to be inside the terminal cover. The winding end of the striated body to prevent the end of the winding of the striated body from rolling up, after the terminal cover is covered, the ending end of the striated body is introduced into the cutout opening of the terminal cover. Before moving the bobbin cover so as to overlap the inside of the terminal cover and cover the winding bobbin, the winding end of the striatum is guided inside the terminal cover outside the bobbin cover. An object of the present invention is to provide a method for winding a strip.

According to a third aspect of the present invention, there is provided a method of winding a filament according to the first or second aspect, wherein a winding end of the filament is wound with a flange of a bobbin and a bobbin. It is an object of the present invention to provide a method of winding a filament, wherein the winding is carried out from a radial direction of the winding bobbin to the winding bobbin through an axial gap between the winding bobbin and an end of the cover.

According to a fourth aspect of the present invention, there is provided a method for winding a filament according to the first or second aspect, wherein a winding end of the filament is wound with a flange of a bobbin and a bobbin. It is an object of the present invention to provide a winding method of a filament which is characterized in that it is bent in the axial direction from the radial direction of the winding bobbin and wound around the winding bobbin through a radial gap between the winding bobbin.

According to a fifth aspect of the present invention, there is provided a winding device for detachably supporting a winding bobbin on which a filament is to be wound, and a full winding of the filament on one of the winding portions. Means for shifting the striated body from the taken-up bobbin to the empty winding bobbin on the other winding section to continuously wind the striated body, and corresponding winding provided at each winding section A wire that covers the bobbin after the striated body is fully wound, covers the terminal cover, guides the end of the striated winding through the notch opening of the terminal cover into the terminal cover, and prevents the wrapped end of the striated body from falling off. In the striated winding device provided with a striated body preventing means, after covering the terminal cover, and before the winding end of the striated body is introduced into the notch opening of the terminal cover, Bobi that moves so as to overlap the inside of the winding bobbin A winding device for a striated body, comprising: a cover; and a bobbin cover advance / retreat means for advancing the bobbin cover inside the terminal cover or retreating to a position off the terminal cover. It is in.

According to a sixth aspect of the present invention, there is provided a wire winding device according to the fifth aspect, wherein the bobbin cover moving means moves the bobbin cover in the axial direction of the terminal cover. It is an object of the present invention to provide a wire winding device comprising a movement mechanism and a bobbin cover lifting mechanism for lifting and lowering the bobbin cover at a position where the bobbin cover is separated from the terminal cover in the axial direction.

As described above, when the bobbin cover is disposed so as to cover the winding bobbin so as to overlap the inside of the terminal cover covered on the fully wound winding bobbin, the winding end end of the striated body becomes Since the wire is guided inside the terminal cover outside the bobbin cover, even if the linear speed of the wire is increased, the winding end of the wire is wound on the wire winding layer on the winding bobbin on the full winding side. Will not hurt.

The bobbin cover moves to the inside of the terminal cover after the terminal cover is put on and before the winding end of the striated body is introduced into the notch opening of the terminal cover. May move so as to move forward simultaneously with the movement to cover the terminal cover, or may move so as to move forward before the movement to cover the terminal cover.

In particular, the winding end of the striated body rotates while meandering toward the surface as the winding bobbin rotates, and this meandering portion passes through a gap between the flange of the winding bobbin and the bobbin cover. When colliding with the bobbin cover, the momentum for colliding against the surface of the striated winding layer on the winding bobbin is reduced, so that the winding end of the striated body is rotated by the winding bobbin. The terminal bobbin is pressed against the inner peripheral surface of the terminal cover by the centrifugal force generated by the terminal bobbin, and is stable between the terminal cover and the bobbin cover without rotation until the rotation of the winding bobbin stops.

Further, when the winding end of the striated body is wound while being bent in the axial direction from the diametric direction of the winding bobbin through the radial gap between the flange of the winding bobbin and the end of the bobbin cover, Since the winding end of the striated body is subjected to the bending motion and the contraction at the gap, it is possible to more efficiently prevent the wrapping end of the striated body from being violent as compared with the case where the winding end is simply squeezed.

Further, since the bobbin cover only moves with respect to the winding bobbin by the linear motion of the axial motion and the vertical motion, the bobbin cover does not require a complicated structure.
Equipment can be provided economically overall.

Even if it is attempted, the bobbin cover 40 disposed so as to cover the winding bobbin 12 inside the terminal cover 24 may cause the winding end 1a to be beaten against the striatum winding layer 1A on the winding bobbin 12. Absent. When the bobbin cover 40 advances, the end portion 40a of the bobbin cover 40 brings the striated body 1 toward the flange 12a in the axial direction of the winding bobbin 12, so that the winding end end is on the winding bobbin 12. Stria winding layer 1A
Therefore, it can be seen that the bobbin cover 40 has the same function as the spiral passage of the terminal cover 24.

As described above, the winding end 1a of the striated body 1 is not straight but is drawn into the terminal cover 24 in a meandering state.
Before passing through the gap (portion indicated by g) between the flange 12a of the winding bobbin 12 and the end 40a of the bobbin cover 40, it collides with the end 40a of the bobbin cover 40 and The momentum for colliding against the upper striatum winding layer 1A is reduced, and the winding end 1a is pressed against the inner peripheral surface of the terminal cover 24 by centrifugal force due to the rotation of the winding bobbin 12, so that the terminal It is stable without falling in the cover 24.

After the rotation of the winding bobbin 12 is stopped, the bobbin cover 40 is retracted by the bobbin cover advance / retreat means 42 in the order of positions C, B and A in FIG. 4, and the terminal cover 24 is also retracted to the position in FIG. The fully wound take-up bobbin 12 is removed from the take-up section 10, a new empty take-up bobbin 12 is supported on the take-up section 10, and the fully wound filament 1 is transferred at the take-up section 10 ′. I am waiting for it.

When the striated body 1 is fully wound at the winding section 10 ', the winding section 10' is moved from the winding section 10 'to the opposite direction as before.
0, and the striatum 1 is wound at the winding section 10 '.
Can be stabilized by the terminal cover 24 'and the bobbin cover 40' in the same manner as described above.

In the above method, the collar 1 of the winding bobbin 12
2a and the minimum gap g between the end 40 of the bobbin cover 40
Has been described in the axial direction of the winding bobbin 12 as shown in FIGS. 4 to 6, but this minimum gap g is the radial direction of the winding bobbin 12 as shown in FIGS. The same can be applied to the case.

In this method, the bobbin cover 40 covers substantially the entire length of the winding bobbin 12, as shown in FIG. 8, so that the winding end 1a is beaten against the filament winding layer 1A on the winding bobbin 12. There is no room for the winding, and the winding end 1a is drawn in from the radial direction through the cutout opening 24a of the terminal cover 24, and then is bent and wound in the radial gap g in the axial direction. The momentum of the meandering portion 1b of the end 1a is further reduced, and the run-up of the winding end 1a can be more effectively suppressed than in the embodiments of FIGS.

In the above embodiment, the bobbin cover 4
Although 0 and 40 'are cylindrical forms completely closed in the circumferential direction, the winding end 1a of the striatum blocks the striking of the striatum winding layer 1A, and the wrapping end 1a Any other form can be used as long as the gap g capable of attenuating the runaway of 1a can be formed. For example, it can be in the form of a cage or other similar forms.

Further, as described above, the method of the present invention can effectively suppress the runaway of the winding end 1a, but it goes without saying that the method may be used in combination with the prior art shown in FIG. .

Further, in the above embodiment, the bobbin covers 40, 40 'are not covered with the terminal covers 24, 24', and the winding end 1a of the filament 1 is
Before being introduced into the cutout openings 24a, 247a of the 24 ', the bobbin covers 40, 40' move inside the terminal covers 24, 24 '.
May be simultaneously moved forward in accordance with the movement to cover the wire, or the striated body 1 may be moved by the striated body shifting means 32 in preparation for shifting to the next winding portion 10 '. After being brought to the side, the terminal cover 24,
It may move forward before the movement to put 24 'on.

[0053]

According to the present invention, as described above, after the terminal cover is put on the fully wound take-up bobbin, the winding end of the striatum is introduced into the cutout opening of the terminal cover. Previously, if the bobbin cover is moved so as to cover the bobbin while overlapping the inside of the terminal cover, the winding end of the striated body is guided inside the terminal cover outside the bobbin cover. Even if the linear velocity of the body is increased, the winding end of the striated body does not damage the striated winding layer on the winding bobbin on the full winding side.

In particular, the winding end of the striated body rotates while meandering toward the surface as the winding bobbin rotates, and this meandering portion passes through a gap between the flange of the winding bobbin and the bobbin cover. When colliding with the bobbin cover, the momentum for colliding against the surface of the striated winding layer on the winding bobbin is reduced, so that the winding end of the striated body is rotated by the winding bobbin. The terminal bobbin is pressed against the inner peripheral surface of the terminal cover by the centrifugal force generated by the terminal bobbin, and is stable between the terminal cover and the bobbin cover without rotation until the rotation of the winding bobbin stops.

Further, when the winding end of the filament is bent and wound in the axial direction from the diameter of the winding bobbin through the radial gap between the flange of the winding bobbin and the end of the bobbin cover, Since the winding end of the striated body is subjected to the bending motion and the contraction at the gap, it is possible to more efficiently prevent the wrapping end of the striated body from being violent as compared with the case where the winding end is simply squeezed.

Further, since the bobbin cover only moves with respect to the winding bobbin by the linear motion of the axial motion and the vertical motion, no complicated structure is required.
Equipment can be provided economically overall.
