Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of winding a long linear object, and more particularly to a method for winding a linear object, a method for winding a linear object, and a method for winding a linear object. Related to an attachment device.

[0002]

2. Description of the Related Art In most cases, a long linear body such as an optical fiber or an electric wire is wound on a bobbin and handled. A winding portion in an electric device, a communication device, a measuring instrument, and the like is also configured by a predetermined linear body being wound multiple times around a core member.

[0003] Regarding the winding technique of a linear body, many techniques have already been developed and put to practical use, and improvements relating to this technique have been made without interruption.

[0004] When a winding structure is formed using a linear body, the midpoint of the linear body (1/2 of the total length) is applied to the winding surface of the bobbin, and the left half and the right half of the linear body are aligned. The winding may be alternately and multiplely arranged. An optical fiber gyro can be cited as a typical example of a device having such a winding structure. The reason why such a winding structure is created in an optical fiber gyro is that when light propagates counterclockwise or clockwise through the optical fiber winding, characteristic fluctuations caused by temperature (heat), stress, etc., cause left-right symmetry. It is because it shows. For an optical fiber gyro, this is an indispensable matter for ensuring stable optical characteristics.

[0005] The above-mentioned winding structure is formed by winding the linear body alternately and multiplexly at the middle point of the linear body as a winding start portion, so that a special technique is required. A long linear body is also desired to be easy to use in such handling.

[0006]

In response to these technical needs, the problems left in the prior art are as follows.

It is preferable to use a long linear body wound on a bobbin in order to handle the long linear body. However, it is impossible to rewind the linear body wound on the bobbin from the middle point. is there. As a countermeasure, it is conceivable to use two bobbins in which the linear bodies are wound by equal amounts and connect the rewind ends of these linear bodies to each other. However, this is not practical because the characteristics of the connecting portion of the linear body may be significantly deteriorated. As another method, it is conceivable to wind the bundled linear body into two bobbins. This means that the wire is wound by half from one end and the remaining wire is wound from the other end, so that the wire is wound on two bobbins by half. When using this method, handling of the bundled linear body becomes a bottleneck. That is, since the bundled linear body not wound on the bobbin is easily entangled and easily broken, it becomes difficult to mechanically perform the above-described winding operation. Therefore, in the latter case, manual winding must be performed depending on the operator, and therefore, a reduction in work efficiency, a variation in winding state (quality) and an increase in cost cannot be avoided.

On the other hand, when the above-described winding structure is formed by using a linear body wound around a half of the two supply bobbins,
The linear body alternately unwound from each supply bobbin is wound alternately (left-handed / right-handed) and multiple times around the core member. The alternate winding means is mechanized. Incidentally, in the case of the winding technique disclosed in Japanese Utility Model Laid-Open Publication No. 1-132908, a pair of left and right disks and a core member between the disks are held on the same axis, and a wire on one supply bobbin side is provided. When the body is wound around the core member, one supply bobbin is taken out of the disk while the other supply bobbin is housed in the disk, and the winding operation is performed by this, and the linear body on the other supply bobbin side is wound around the core. When wound around a member, while storing one supply bobbin in the disk, taking out the other supply bobbin from the disk and performing a winding operation by this,
Hereinafter, these operations are repeated.

This known technique has the following problems. One of them is that the control difficulty is increased because a high-level operation of alternately holding each supply bobbin is required. The other is that the supply bobbin is frequently changed, so that it is difficult to obtain the stability of the supply bobbin and the winding state (quality) tends to vary. In addition, when the supply bobbin is changed, wasteful operation tends to increase. Still another is that the linear body is likely to be twisted or disconnected when the supply bobbin is taken in and out. One of the other reasons is that a disk having a diameter larger than that of the bobbin is simultaneously rotated at the time of winding, so that high speed operation becomes difficult and work efficiency is reduced.

SUMMARY OF THE INVENTION In view of the above problems, the present invention relates to a technique for winding or winding a linear body, to improve the quality of a winding state, to alleviate technical difficulty, to streamline operations, An object of the present invention is to provide a method and an apparatus capable of reducing costs.

Therefore, each part in the winding system of FIG. 1 is composed of the power machine 11 → the guide roller 14 → the dancer mechanism 15 → the rotary encoder 20 → the tension abnormality detecting mechanism 22 → the swing mechanism 26 →
They are arranged in the order of the power machines 13. In the winding system shown in FIG. 2, the tension control power machine 12 is at the front stage, the winding power machine 13 is at the rear stage, and the guide roller 14 and the rotary encoder 2 are provided.

Measuring instruments and sensors are electrically or electronically connected to a control panel (not shown).

The raw material bobbin 35, the first winding bobbin 36, the second winding bobbin 37 and the like shown in FIGS. 1 to 3 are all well known. The linear body 38 is made of ultrafine glass such as an optical fiber, a metal wire such as an electric wire, a wire made of a synthetic resin, or a fiber or thread made of a single material or a composite material.・ It may be a string. As a specific example of the linear member 38, a coated optical fiber can be given. In particular, in the case of the linear body 38 made of an optical fiber, this is often a polarization-maintaining optical fiber. Note that the ordinal numbers of "first" and "second" on both winding bobbins 36 and 37 are given for convenience in order to distinguish them, and have no special meaning.

In the embodiment illustrated in FIGS. 1 to 3, the method for winding a linear body according to the present invention is as follows. A long linear body 38 unwound from a raw bobbin 35 is firstly wound on a bobbin 36.
When winding on

First, as shown in FIG. 1, a raw material bobbin 35 on which a linear body 38 having a predetermined length or more is wound is mounted on the rotating shaft of the power motor 11, or an empty first bobbin is used.
The winding bobbin 36 is mounted on the rotating shaft of the power machine 13 and the linear body 38 partially unwound from the raw material bobbin 35 is transferred to the guide roller 14 → the dancer mechanism 15 → the rotary encoder 20 → the abnormal tension detecting mechanism 22. → Swing mechanism 26
→ Wrap around the first winding bobbin 36 in this order, and
The rewinding end of No. 8 is temporarily fixed to the winding surface of the first winding bobbin 36.

After the preparation as shown in FIG. 1 is completed, the apparatus shown in FIG. When operating, the raw material bobbin 35
The linear body 38 is rewound from the first winding bobbin 36 via the guide roller 14, the dancer mechanism 15, the rotary encoder 20, the tension abnormality detecting mechanism 22, the swing mechanism 26, and the like. At this time, the dancer mechanism 15 keeps the tension of the linear body 38 constant, and the rotary encoder 2
0 indicates that the rotation amount is integrated to calculate the winding amount of the linear body 38 wound on the first winding bobbin 36, and the tension abnormality detecting mechanism 22 determines whether or not the tension abnormality occurs in the linear body 38. Is detected. Further, in the swing mechanism 26, the two pinching rollers 30
3, the swinging member 32 sandwiching the linear body 38 through 31 as shown in FIG. 3 reciprocates in the direction of the arrow in FIG. A single winding bobbin 36 is wound around the winding surface of the winding bobbin 36 in a multiple manner. Thus, when a predetermined amount (predetermined length) of the linear body 38 is wound on the first winding bobbin 36, the apparatus in FIG. 1 automatically stops.

In the above winding step, if an abnormal tension occurs in the linear body 38, the abnormal tension detecting mechanism 22 itself operates to eliminate the abnormal tension, or the abnormal tension detecting mechanism 22 operates. The operation of the apparatus of FIG. 1 is stopped through a control panel (not shown).

In the above winding step, the raw material bobbin 35
Of the linear body 38 wound on the first winding bobbin 3
6 is equal to the amount of the linear body 38 to be wound,
The process is completed when the raw material bobbin 35 becomes empty. On the other hand, when the amount of the linear body 38 wound on the raw material bobbin 35 exceeds the amount of the linear body 38 to be wound on the first winding bobbin 36, the linear body 38 having a predetermined length is used. 3
The process is completed when 8 is wound on the first winding bobbin 36. In this case, the linear body 38 is cut between the raw material bobbin 35 and the first winding bobbin 36.

Next, as shown in FIG. 2, the first winding bobbin 36 after winding the linear body 38 is mounted on the rotating shaft of the power machine 12 or the empty second winding bobbin 37 is mounted on the power machine 13. The linear body 38 attached to the rotating shaft and partially unwound from the first winding bobbin 36 is connected to the rotary encoder 2.
0 → tension abnormality detecting mechanism 22 → swing mechanism 26 → second winding bobbin 37, and the rewind end of linear body 38 is temporarily fixed to the winding surface of second winding bobbin 37.

After the preparation as shown in FIG. 2 is completed, the apparatus shown in FIG. After the operation, the linear body 38 rewound from the first winding bobbin 36 while being subjected to the tension control by the power machine 12 is rotated by the rotary encoder 20 and the tension abnormality detecting mechanism 2.
2. It is wound on the second winding bobbin 37 via the swing mechanism 26 and the like. At this time, the rotary encoder 20,
The tension abnormality detection mechanism 22, the swing mechanism 26, and the like operate in the same manner as described above. Therefore, the linear body 38 is aligned and wound multiple times on the winding surface of the second winding bobbin 37 as in the case described above.

The amount of the linear body 38 wound on the second winding bobbin 37 and the linear body 3 remaining on the first winding bobbin 36
When the quantity of 8 substantially coincides, the rotary encoder 20 detecting this stops the apparatus of FIG. 2 via a control panel (not shown). This means that the first winding bobbin 36 has wound half of the series of linear bodies 38 and the remaining half has been wound with the second winding bobbin 37. Thus, the series of linear bodies 38 are wound around the two winding bobbins 36 and 37 with approximately equal amounts. In addition, about the winding amount of the linear body 38 with respect to both winding bobbins 36 and 37,
The winding amount on the winding bobbin 36 side should be larger than the winding amount on the winding bobbin 37 side, and conversely, the winding amount on the winding bobbin 37 side should be larger than the winding amount on the winding bobbin 36 side. There is also.

The winding method and winding device shown in FIGS. 1 to 3 are of a vertical type in which each rotation axis is horizontal, but there is also a horizontal type in which each rotation axis is vertical. Even in such a horizontal type, a series of linear bodies 38 can be wound on two winding bobbins 36 and 37 in accordance with the contents described above.

When the upper movable base 73 is moved by a feed screw shaft, a forward / reverse rotatable motor is used as a power source. Note that one of the moving table mechanisms 7
The other moving table mechanism 71B, which is symmetrical to 1A, has the same structure as that of the other moving table mechanism 71B except that it is arranged outside the core support 52 and the screw shaft 74 is located at the rear side of the apparatus in FIG. Has the same configuration as the moving table mechanism 71A. Therefore, the description of the other moving platform mechanism 71B will be omitted by referring to the description of the one moving platform mechanism 71A. As is clear from these explanations, the movable platform (upper movable platform 73) of both movable platform mechanisms 71A and 71B.
Can move over a region orthogonal to or parallel to the axis of the core member 41.

The two supply mechanisms 81 in FIGS.
A.81B has the same configuration as each other, and these are mounted symmetrically on the moving platform mechanisms 71A and 71B. The supply mechanism 81A includes a power unit 82 for rotation and parts and members related thereto, and a clutch 89 and parts and members related thereto. As an example, a power machine 82 composed of a motor has a trivial rotating shaft 83. As will be described later, the rotating shaft 83 supports a supply bobbin (36 or 37) for a linear body, or supplies the rotation of the power machine 82 via a clutch 89 to the supply bobbin (36 or 37).
And to attach / detach to transmit the rotation of the power machine 82 to the core member 41. A bearing 84 is fitted to the end of the rotating shaft 83 as shown in FIG. As clearly shown in FIGS. 9 and 10, the rotating plate 85 has three mounting portions 86 to 88 protruding radially, and this is mounted on the intermediate portion in the longitudinal direction of the rotating shaft 83. The clutch 89 having an arm shape has a braking portion 90 at one end and a pressure roller 91 at the other end, and a middle portion in the length direction of the clutch 89 is attached to an end of the mounting portion 86 of the rotating plate 85 by well-known shaft support means. It is mounted so that it can swing and rotate. The spring 92 is for pulling the braking portion 90 of the clutch 89 toward the rotating plate 85, so that the spring 92 is hung over the braking portion 90 and the rotating plate 85. Another mounting portion 87 on the rotating plate 85
An arm 94 having a detection roller 93 at the tip is rotatably attached to the end. The spring 95 is also hung over the tip of the arm 94 and the rotary plate 85 to attract the detection roller 93 of the arm 94 toward the rotary plate 85. A detection switch (micro switch) 9 corresponding to the tip of the arm 94 so as to be freely contactable therewith.
6 are arranged. The detection switch 96 is to stop the power unit 82 by switching off via the detection roller 92 when a tension abnormality occurs in the linear body 38 unwound from the supply bobbin (36 or 37).
The detection switch 96 is also attached to a member (not shown) extending from the rotary plate 85 and holds a predetermined position. A guide roller 97 for a linear body is rotatably attached to the end of the remaining one attachment portion 88 of the rotating plate 85. The supply mechanism 81A having the above configuration is mounted on the mounting plate 98 shown in FIG.
Mounting plate 98 in this case, as can be turned to the arrow R ₁₁ to R ₁₂ direction in FIG. 5 (reversal), and rotatably mounted on the upper moving base 73 via a pivot shaft 99. The fulcrum shaft 99 has a motor (not shown) rotatable in the normal and reverse directions via a transmission system (eg, a gear transmission system) not shown.
Are connected. The other supply mechanism 81B, which is symmetrical to the one supply mechanism 81A, is attached to the movable platform (upper movable platform 73) on the movable platform mechanism 71B side, except that it is assembled to one of the supply mechanisms 81B. It has the same configuration as 81A. Therefore, the other supply mechanism 8
The description of 1B is omitted by referring to the description of one supply mechanism 81A. As can be understood from these descriptions, the directions of the two supply mechanisms 81A and 81B can be changed within the range in which the mounting plate 98 rotates.

The two tension applying mechanisms 101A and 101B shown in FIGS. 5 to 10 have the same structure, and are mounted symmetrically on the moving platform mechanisms 71A and 71B. As is clear from FIGS. 9 and 10,
One tension applying mechanism 101A includes an electric motor (torque motor) 102 for applying tension and a roller 103 for transmitting tension attached to an output shaft thereof. Tensioning mechanism 101A is to be freely moved in the arrow Z ₃₁ to Z ₃₂ direction in FIG. 5, for example, assembled on the mounting plate 98 via the guide means of the rail type, pull further pushing it in a predetermined direction For example, a pneumatic cylinder (not shown) is connected to the tension applying mechanism 101A. Thus, the tension applying mechanism 101A assembled on the mounting plate 98 is adjacent to the one supply mechanism 81A, and applies tension to the supply bobbin (36 or 37) supported by the rotating shaft 83 of the power machine 82. Roller 10 for transmission
3 can be pressed and released. Incidentally, when the roller 103 is pressed against the supply bobbin (36 or 37), a tension (load) for tensioning the linear body 38 is applied to the supply bobbin, and the roller 103 is supplied to the supply bobbin (36 or 37). When it is separated, the rotation of the power machine 82 can be transmitted to its supply bobbin. The other tension applying mechanism 101B, which is symmetrical to the one tension applying mechanism 101A, has one tension applying mechanism except that it is assembled to a movable platform (upper movable platform 73) on the movable platform mechanism 71B side. Mechanism 101A
It has the same configuration as. Therefore, the description of the other tension applying mechanism 101B will be omitted by referring to the description of the one tension applying mechanism 101A.

The concept of the method for winding a linear body according to the present invention will be described with reference to the examples illustrated in FIGS. 4 (A) to 4 (D).
As described above, the linear body 38 used in this example is divided into two supply bobbins 36 and 37, and a crossing portion extending between the two supply bobbins 36 and 37 is defined as a winding start portion 39. . The core member 41 around which the linear body 38 is wound is also as described above.

In FIG. 4A, first, the supply bobbin 36 shown by the solid line in FIG. 4 and the supply bobbin 37 shown by the imaginary line in FIG. 4 are placed in parallel with the core member 41 interposed therebetween. The winding start portion 39 of the body 38 is
Apply to the right peripheral surface of. Next, the supply bobbin 3 of the virtual line
7 is shifted to the right side surface of the core member 41 as shown by a solid line, so that the core member 41 and the core member 41 are arranged in tandem, and the supply bobbin 37 is connected to the right side surface of the core member 41. After this, the supply bobbin 37 is rotated at a constant speed in the counterclockwise direction to co-rotate the core member 41, or the supply bobbin 36 is traversed leftward at a constant speed in synchronization with the rotation. Thus, the linear body 38 unwound from the supply bobbin 36 is left-aligned from the right side to the left side by the counterclockwise rotation of the core member 41 and the left traverse of the supply bobbin 36 on the peripheral surface of the core member 41. You. That is, a left-handed first winding layer is formed on the peripheral surface of the core member 41. When the alignment winding is completed, the left traverse of the supply bobbin 36 and the counterclockwise rotation of the supply bobbin 37 are stopped.

In FIG. 4B, the supply bobbin 37 is cut off from the right side surface of the core member 41 so as to be parallel to the core member 41, and traverses to the left.
Are arranged in a tandem state with respect to the core member 41 and connected to the left side surface of the core member 41. After this, the supply bobbin 36 is rotated clockwise at a constant speed to co-rotate the core member 41, or the supply bobbin 37 is traversed leftward at a constant speed in synchronization with the rotation. Thus, on the first winding layer of the core member 41, the linear body 38 unwound from the supply bobbin 37 is rotated from right to left by the clockwise rotation of the core member itself and the left traverse of the supply bobbin 37. Wound right aligned over. That is, the right winding second winding layer is formed on the first winding layer (left winding). When the alignment winding is completed, the clockwise rotation of the supply bobbin 36 and the left traverse of the supply bobbin 37 are temporarily stopped.

In FIG. 4 (C), the supply bobbin 36 is cut off from the left side surface of the core member 41 so as to be parallel to the core member 41, and the supply bobbin 37 traversed leftward.
Are arranged in a tandem state with respect to the core member 41 and connected to the left side surface of the core member 41. After this, the supply bobbin 37 is rotated at a constant speed in the counterclockwise direction to rotate the core member 41 together, or in synchronization with this, the supply bobbin 36 is traversed rightward at a constant speed. Thus, on the second winding layer of the core member 41, the linear body 38 that is unwound from the supply bobbin 36 from the left side by the counterclockwise rotation of the core member itself and the right traverse of the supply bobbin 36 Left-handed aligned over the right side. That is, the left-handed third winding layer is formed on the second winding layer (right-handed winding). Even after the completion of the aligned winding, the supply bobbin 36 is stopped from rotating counterclockwise and the supply bobbin 37 is stopped from traversing rightward.

In FIG. 4D, the supply bobbin 37 is separated from the left side surface of the core member 41 so as to be parallel to the core member 41, and traverses rightward.
Are arranged in tandem with the core member 41 and connected to the right side surface of the core member 41. After this, the supply bobbin 36 is rotated clockwise at a constant speed to rotate the core member 41 together, or in synchronization with this, the supply bobbin 37 is traversed rightward at a constant speed. Thus, on the third winding layer of the core member 41, the linear body 38 unwound from the supply bobbin 36 is rotated from left to right by the clockwise rotation of the core member itself and the right traverse of the supply bobbin 37. Wound right aligned over. That is, the right-handed fourth winding layer is formed on the third winding layer (left-handed winding). Even after the completion of the aligned winding, the supply bobbin 36 is stopped from rotating counterclockwise and the supply bobbin 37 is stopped from traversing rightward.

After FIG. 4D, the supply bobbin 36 is cut off from the right side surface of the core member 41 to be parallel to the core member 41, or the supply bobbin 37 traversed leftward is attached to the core member 41. On the other hand, it is connected in a tandem state to the right side surface of the core member 41. That is, this means that the state returns to the solid line state in FIG. Therefore, when the fifth and subsequent winding layers are formed on the fourth winding layer, FIG.
(A) to (D) will be repeated.

FIG. 5 shows a wire winding device according to the present invention.
10 to FIG. 10 are used to carry out the above-described method for winding a linear body. An example of this will be described below.

In FIG. 5, a supply bobbin 36 is mounted on a rotating shaft 83 of a power unit 82 on the supply mechanism 81A side. Similarly, the supply bobbin 37 is also loaded on the rotating shaft 83 of the power unit 82 on the supply mechanism 81B side. As shown in FIGS. 6 and 8, adapters 42 and 43 are attached to both sides of the core member 41 arranged at the center of the apparatus in FIG. Core member 41 with both adapters 42 and 43 mounted
When the support member 61 is disposed at the center of the apparatus in FIG.
1 is supported from below. When core member 41 thus supported, the winding core support 51 to move from the left side of FIG. 8 in the arrow Y ₁₁ direction and the arrow X ₁₂ direction, from the right side of FIG. 8 arrow Y ₁₁ direction and the arrow X ₁₁ direction The center shaft 48 is supported at both ends via the moving core support 52. That is, the core member 41
Are supported rotatably forward and backward via both core supports 51 and 52 (forward rotation = clockwise, reverse rotation = counterclockwise).

After the core member 41 is thus supported,
In order to obtain the state shown in FIG. 4A, each part performs a series of operations as described below. Initially, the moving table mechanism 71A on the left side of FIG.
Upper moving base 73 move in the arrow Z ₂₂ direction in the drawing, the upper moving base 73 on the right side of FIG. 5 movable carriage mechanism 71B to move the arrow Z ₂₁ direction in FIG. In the above. Subsequently, the motor 75 for the carriage mechanism 71A reversely rotates in seconds to minutes, or the motor 75 for the carriage mechanism 71B.
Rotates forward in seconds to minutes. Moving table mechanism 71
Screw shaft 74 to reverse rotation via the motor 75 for the A moves the upper moving base 73 of the mechanism 71A side after moving to the arrow Z ₂₂ the direction of the arrow X ₃₂ direction in FIG. 5, the mobile platform mechanism Screw shaft 74 that rotates forward via electric motor 75 for 71B
Moves the upper moving base 73 of the mechanism 71B side after moving to the arrow Z ₂₁ the direction of the arrow X ₃₁ direction in FIG. As a result of these parts performing these movements, the supply bobbin 36 (supply mechanism 81A) on the upper movable platform 73 on the movable platform mechanism 71A side is provided.
Side) and the supply bobbin 37 (supply mechanism 81B side) on the upper moving table 73 on the moving table mechanism 71B side, as described with reference to FIG. , And the winding start portion 39 of the linear body 38 is applied to the right peripheral surface of the core member 41. FIG. 11 (01) schematically shows such a state. Incidentally, an arrow X ₃₁ -X ₃₂ line in (01) in FIG. 11 is a arrow X ₃₁ -X ₃₂ line the same line in FIG. Next, the upper moving table 7 on the moving table mechanism 71A side.
3 stands by at the above-mentioned moving position, and only the upper moving table 73 on the moving table mechanism 71B side returns to the original position by the reverse operation. In the process of returning the upper moving table 73 on the moving table mechanism 71B side, the winding start section 39 of the linear body 38 is engaged with the direction changing section 47 of the adapter 43. Then, move the moving table mechanism 71B via the electric motor 75 and the screw shaft 74 for this arrow X ₃₁ direction in FIG. 5 by a predetermined distance. Therefore, the power machine 82 on the side of the mechanism 71B and incorporated in the supply mechanism 81B
Is connected to the right end of the center shaft 48 (the shaft for the core member 41) in the adapter 43. In this case, the connecting means between the center shaft 48 and the rotating shaft 83 is a clutch-type fitting connection or a pressure-type connection using frictional force. Thereafter, the core member 41 is held by the rotation shaft 83 on the supply mechanism 81B side and one of the core support members 51. That is, this is the same as the matter described with reference to FIG. This also means that each part is displaced in the order of (01) → (02) → (03) → (04) in FIG. 11 with reference to FIG. While each part is displaced in this way, the core member 41
Is stopped by the support member 61, and the rollers 103 of the tension applying mechanisms 101A and 101B also
In order to apply tension to the linear body 38, a load is applied to the rotation of the two supply bobbins 36 and 37 while pressing the pressure rollers 91 of the clutches 89 against the peripheral surfaces of the two supply bobbins 36 and 37. After such a state is obtained, the support member 61 separates from the core member 41 to release the restriction, and the pressure roller 91 of the clutch 89 on the tension applying mechanism 101B side also separates from the supply bobbin 37. Release the load on this. With respect to the supply bobbin 36, the tension load is still applied. In the following, in order to wind the linear body 38 on the supply bobbin 36 side around the peripheral surface of the core member 41, the power machine 82 on the supply mechanism 81B side is reversely rotated at a constant speed or the moving table mechanism 71B
The motor 75 is rotated synchronously at a constant speed. The reverse rotation of the supply mechanism 81B-side power machine 82 is performed by rotating the rotation shaft 83 → the rotation plate 85 → the braking unit 90 of the clutch 89 → the transmission bobbin 3 in the transmission order such as the supply bobbin 37
7 and transmitted to the core member 41 in a transmission order such as the rotation shaft 83 → the adapter center shaft 48 → the core member 41. Further, by the motor 75 for moving stand mechanism 71A rotates forward, the moving table mechanism 71A is because traverses the arrow X ₃₁ direction in FIG. 5 through the screw shaft 74, the mechanism 71A of the upper moving base 73 on Supply bobbin 36 (supply mechanism 81)
A side) also traverses in the same direction. The core member 41
The rotation speed of the supply bobbin 36 and the traverse speed of the supply bobbin 36 are synchronized with each other in that the supply bobbin 36 moves by a distance corresponding to one pitch (the diameter of the linear body 38) for one rotation of the core member 41. The left traverse amount of the supply bobbin 36 is equal to the effective length of the core member 41. When the relative relationship between the parts is as described above, the core member 41 winds the linear member 38 around the core member 41 while rewinding the linear member 38 on the supply bobbin 36 side by the rotational force transmitted thereto. wound on the surface, the supply bobbin 36, the linear body 38 moves in the arrow X ₃₁ direction in FIG. 5 according to the speed to be wound around the core member 41. That is, this is the same as the winding of the linear body described with reference to FIG. This is also shown in FIG.
1 means that the respective parts are displaced in the order of (04) → (05) → (06) in FIG. Therefore, the linear member 38 unwound from the supply bobbin 36 is provided on the peripheral surface of the core member 41.
Are aligned left-handed from right to left to form a left-handed first winding layer. When the left-handed alignment is completed, the left traverse motion and the supply bobbin rotation described above are stopped.

After the above-described winding of the linear body is completed, FIG.
In order to obtain the state (B), each part performs a series of operations as described below. First, the supply mechanism 81A after left traversing with the moving table mechanism 71A and the upper moving table 73 thereon.
(Including the supply bobbin 36) to the tandem state with respect to core member 41, an upper moving base 73 of the mechanism 71A side in the arrow Z ₂₁ direction in FIG move the arrow X ₃₁ direction in FIG. 5 Or move. This is followed by supply mechanism 81A central axis the rotation axis 83 of the side 48 for connecting the left end of (the axis for core member 41), an upper moving base 73 of the mechanism 71A side in the arrow X ₃₂ direction in FIG. 5 Moving. Thereafter, the core member 41 is held by the rotation shaft 83 on the supply mechanism 81A side and the other core support 52. In the process of returning the upper moving table 73 on the moving table mechanism 71A side, the winding start section 39 of the linear body 38 is engaged with the direction changing section 46 of the adapter 42. In synchronization with the tandem connection, the rotation shaft 83 on the supply mechanism 81B side is released from the right side surface of the core member 41, or the supply bobbin 37 is connected to the core member 41.
Order or to parallel with the upper moving table 73 movable carriage mechanism 71B side arrow X ₃₂ direction and the arrow Z ₂₁ direction-arrow X in FIG. 5
Move sequentially in ₃₁ directions. That is, this is because the supply bobbin 36 is arranged in tandem with the core member 41 and the rotation shaft 83 on the supply mechanism 81A is connected to the left end of the center shaft 48, and the upper carriage 73 on the carriage mechanism 71B side. The supply bobbin 37 operates as described above.
Is in parallel with the core member 41. This is also because, with reference to FIG. 11, each part is (06) → (07) →
(08) → (09) → (10) → (11) → (12) → (13) → (14). The movements of these components are performed by turning on the power systems described above. While each part is displaced in this way, the supporting member 61 stops the rotation of the core member 41 and applies a load to the rotation of the two supply bobbins 36 and 37 as described above. After the state is obtained, the release of the restraint of the core member 41 and the release of the load of the supply bobbin 36 alone are also performed in the above-described manner. The following is supply bobbin 3
In order to wind the linear body 38 on the 7th side around the peripheral surface of the core member 41 (above the first winding layer), the power unit 82 on the supply mechanism 81A side

Is rotated in a forward direction at a constant speed. By the forward rotation of the power unit 82 on the supply mechanism 81A side, the supply bobbin 36 and the core member 41 rotate forward in the transmission order described above. Further, the forward rotation of the moving base mechanism 71B electric motor 75, because the moving table mechanism 71B traverses the arrow X ₃₁ direction in FIG. 5 through the screw shaft 74, the mechanism 71B
The supply bobbin 37 (the supply mechanism 81B side) on the upper movable table 73 on the side also traverses in the same direction. Others are as described above. When the relative relationship of each part is as follows, the core member 41 is supplied with the supply bobbin 3 by the rotational force transmitted thereto.
While rewinding the linear body 38 on the 7th side,
5. The supply bobbin 37 is wound around the peripheral surface of the core member 41 according to the speed at which the linear body 38 is wound around the core member 41.
Move in ₃₁ directions. That is, this is the same as the winding of the linear body described with reference to FIG. This also means that each part is displaced as shown in (14) → (15) of FIG. 11 with reference to FIG. Therefore, the core member 4
A linear body 38 unwound from the supply bobbin 36 is wound right and left on the peripheral surface of the supply bobbin 36 from right to left to form a right-handed second winding layer on the first winding layer. It will be. When such a right-handed alignment is completed, the left traverse motion and the supply bobbin rotation described above are stopped.

After the above-described winding of the linear body is completed, FIG.
In order to obtain the state (C), each part performs a series of operations as described below. First, the rotating shaft 83 on the supply mechanism 81A side is released from the left side surface of the core member 41, or the supply bobbin 3
6 for or to parallel to the core member 41, an upper moving base 73 of the moving table mechanism 71A side sequentially moved in the arrow X ₃₁ direction and the arrow Z ₂₂ direction and the arrow X ₃₂ direction in FIG. Next, the supply mechanism 81B (including the supply bobbin 37) after the left traverse with the movable platform mechanism 71B and the upper movable platform 73 thereon.
Of the same mechanism 7
Arrow X ₃₁ direction and the arrow Z of the upper moving base 73 of 1B side 5
Move the ₂₂ direction, the mounting plate 98 of the mechanism 71B side or rotated 180 degrees around the fulcrum shaft 99 in the arrow R ₁₂ direction in FIG. In the process of moving the upper moving table 73 on the moving table mechanism 71B side in this way, the winding start portion 39 of the linear body 38
Is applied to the direction conversion unit 46 of the adapter 42. This is followed by the central axis of the rotary shaft 83 of the feed mechanism 81B side 48 for connecting the left end of (the axis for core member 41), an upper moving base 73 of the mechanism 71B side in the arrow X ₃₂ direction in FIG. 5 Moving. At this point, the core member 41 is rotated by the rotating shaft 83 on the supply mechanism 81B side.
And the other core support 52. As a result,
The supply bobbin 36 is in parallel with the core member 41, the supply bobbin 37 is in tandem with the core member 41, and the rotation shaft 83 on the supply mechanism 81B side is connected to the left end of the central shaft 48. Referring to FIGS. 11 to 12, each part is (15) → (16) → (17) → (18) → (19) → (20) → (21) → (22) →
(23) → (24). Such movement of each part is also performed by turning on a predetermined power system. While each part is displaced in this manner, the support member 61 stops the rotation of the core member 41 or the supply bobbin 3
The application of a load to the rotation of 6.37 is performed in the above-described manner. After such a state is obtained, the restraint of the core member 41 is released or the load of only the supply bobbin 37 is released. This is also performed in the manner described above.
In the following, in order to wind the linear body 38 on the side of the supply bobbin 36 around the peripheral surface (on the second winding layer) of the core member 41, the power machine 82 for the supply mechanism 81B is reversely rotated at a constant speed, The reverse rotation of the electric motor 75 for the mechanism 71A at a constant speed is performed synchronously. Supply mechanism 81B side power machine 8
By the reverse rotation of 2, the supply bobbin 37 and the core member 41 also rotate in the reverse direction. Further, by the reverse rotation of the moving base mechanism 71A for the motor 75, because the moving table mechanism 71A traverses the arrow X ₃₂ direction in FIG. 5 through the screw shaft 74, supplied with on the upper moving base 73 of the mechanism 71A side Bobbin 36 (supply mechanism 81A
Side) also traverses in the same direction. Others are as described above. When the relative relationship between the parts is as described above, the core member 41 rewinds the linear member 38 on the side of the supply bobbin 36 by the rotational force transmitted thereto, and rotates the linear member 38 around the core member 41. The supply bobbin 36 is wound around the
Move the arrow X ₃₂ direction in FIG. 5 in accordance with the eighth winding speed. That is, this is the same as the winding of the linear body described with reference to FIG. This is also shown in FIG.
, Each part is displaced as shown in (24) → (25) → (26) in FIG. Therefore, on the peripheral surface of the core member 41, the linear body 38 unwound from the supply bobbin 36 is aligned left-handed from left to right to form a left-handed third winding layer on the second winding layer. Will be done. When the left-handed alignment is completed, the right traverse motion and the supply bobbin rotation described above are stopped.

After the above-described winding of the linear body is completed, FIG.

As a result, the supply bobbin 36 is in a tandem state with respect to the core member 41, the rotation shaft 83 of the supply mechanism 81A is connected to the right end of the central shaft 48, or the supply bobbin 37 is connected to the core member 41. Each stage of the parallel state is completed. This is Figure 1
2. Referring to FIG. 13, each part is (26) → (27) → (28) in both figures.
→ (29) → (30) → (31) → (32) → (33) → (34). Such movement of each part is also performed by turning on a predetermined power system. While each part is displaced in this manner, the support member 61 stops the rotation of the core member 41 and applies a load to the rotation of the two supply bobbins 36 and 37 in the manner described above. After the state is obtained, the release of the restraint on the core member 41 and the release of the load on only the supply bobbin 36 are also performed in the above-described manner. Hereinafter, the linear body 38 on the supply bobbin 37 side is connected to the peripheral surface of the core member 41 (on the third winding layer).
To rotate the power motor 82 on the side of the supply mechanism 81A at a constant speed in the forward direction, or the motor 75 for the moving table mechanism 71B.
Is rotated synchronously at a constant speed. By the forward rotation of the supply mechanism 81A-side power machine 82, the supply bobbin 36 and the core member 41 also rotate forward. In addition, the reverse rotation of the motor 75 for the moving table mechanism 71B causes the moving table mechanism 71B to rotate.
B traverses from traversing the arrow X ₃₂ direction in FIG. 5 through the screw shaft 74, the supply bobbin 37 (supply mechanism 81B side) located on the upper moving base 73 of the mechanism 71B side in the same direction. Others are as described above. When the relative relationship between the respective parts is as described above, the core member 41 rewinds the linear member 38 on the side of the supply bobbin 37 with the rotational force transmitted thereto, and rotates the linear member 38 around the core member 41. wound on the surface, the supply bobbin 37, the linear body 38 moves in the arrow X ₃₂ direction in FIG. 5 according to the speed to be wound around the core member 41. That is, this is the same as the winding of the linear body described with reference to FIG. This is also shown in FIG.
, Each part is displaced as shown in (34) → (35) in FIG. Therefore, on the peripheral surface of the core member 41,
The linear body 38 unwound from the supply bobbin 37 is aligned right-handed from left to right, and a right-handed fourth winding layer is formed on the third winding layer. When such a right-handed alignment is completed, the right traverse motion and the supply bobbin rotation described above are stopped.

After the above-described winding of the linear body is completed, the rotating shaft 83 on the supply mechanism 81A side is released from the right side of the core member 41, and the supply bobbin 36 is made parallel to the core member 41. The upper moving table 7 on the moving table mechanism 71A side
3 move in the arrow X ₃₂ direction and the arrow Z ₂₂ direction in FIG. 5,
Or rotated 180 degrees in the arrow R ₁₁ direction in FIG. 5 the mounting plate 98 of the mechanism 71A side about the fulcrum shaft 99, the mechanism 71
Upper moving base 73 of the A-side or moved in the arrow X ₃₁ direction. This means that, with reference to FIG.
→ (36) → (37) → (38) → (39). Such movement of each part is also performed by turning on a predetermined power system. While the respective parts are displaced in this manner, the support member 61 stops the rotation of the core member 41 and applies a load to the rotation of the supply bobbins 36 and 37 in the manner described above. (39) in FIG.
Is the same state as (01) in FIG. That is, this means that each unit returns to (01) in FIG. Therefore, when forming the fifth and subsequent winding layers on the fourth winding layer, (01) to (38) shown in FIGS. 11 to 13 are repeated.

And does not match the one shown in the other figures,
This is intentionally indicated as such for the sake of explanation. Of course, there is an embodiment in which the clutch 89 is separated from the tension applying mechanisms 101A and 101B. In such a case, a pushing member (not shown) instead of the tension transmitting roller 103 is applied to the pressing roller 91 of the clutch 89, and the roller 103 of the electric motor 102 directly contacts the supply bobbins 36 and 37. Become like

In the above-described embodiment of the wire winding method,
Each time one of the supply mechanisms 81A and the other supply mechanism 81B traverses leftward or rightward, the linear body 38 that rewinds and supplies the supply bobbins 36 and 37 to the core member 41 is switched alternately. , Such a linear body 38
Is switched every time the two supply mechanisms 81A and 81B make one reciprocation (left traverse + right traverse), or
It may be performed every two round trips or more. Other, 1 /
The linear body 38 may be wound around the core member 41 by arbitrarily combining 2 left traverse, 1/2 right traverse, left traverse (one way), right traverse (one way), and reciprocating traverse.

According to the first aspect of the present invention, there is provided a method of winding a linear body having a required length from a raw bobbin to a first linear body.
And the linear body is wound from the first winding bobbin to the second winding bobbin. Therefore, a series of linear windings divided into two supply bobbins are performed. The body is obtained through a simple step from bobbin to bobbin. Therefore, all of the steps for winding the linear body from bobbin to bobbin can be mechanized, and a high-quality product having no variation in the winding state can be efficiently manufactured.

In the method of winding a linear body according to a second aspect of the present invention, a linear body having a required length is wound from a raw bobbin to a first winding bobbin, and the linear body is wound. Since a half-winding operation is performed from the first take-up bobbin to the second take-up bobbin, a series of linear bodies divided into two equal amounts by two supply bobbins is simplified from a bobbin to a bobbin. It is obtained by going through various steps. Therefore, the same effect as described above can be obtained, and a winding material particularly suitable for an optical fiber gyro can be obtained.

According to a second aspect of the present invention, when the linear body is wound around the core member in the winding step, one supply bobbin is wound around the core. It rotates while maintaining the tandem connection state with the member and the other supply bobbin traverses while maintaining the parallel relationship with the core member. , The core member is rotated stably, and the winding control is easy. Therefore, it is highly useful as a method for winding a linear body. When the reciprocating movement (traverse of return and return) of the supply bobbin in the winding step is one stroke, the linear body is alternately wound (left-handed / right-handed) within a range of 1/2 to 2 or more strokes. Therefore, it is highly versatile in producing various winding products.

The apparatus for winding a linear body according to the present invention includes the above-described winding method including a pair of core support members, a brake-type support member, a moving table mechanism, a supply mechanism for supplying the linear body, and a tension applying mechanism. The structure suitable for performing each of the steps is provided. Therefore, when using the winding device, the above-described winding method can be rationally performed, and as a result, a high-quality wound product can be stably manufactured with high efficiency.
