DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for polishing a wire, for example, a core wire of an optical fiber. More specifically, the present invention relates to an apparatus for cleanly polishing a wire, for example, silicon for coating adhered to a core wire of an optical fiber.

[0002]

2. Description of the Related Art For some wire rods, it is sometimes necessary to polish the outer peripheral surface. For example, in the case of an optical fiber, when connecting the optical fibers to each other or connecting to other devices, it is necessary to peel off the coating of the tip of the optical fiber to expose the core wire portion, and clean the outer peripheral surface by polishing. is necessary. Since the optical fiber is usually protected by a primary coat such as silicon gel and a coating of a soft plastic, etc., even after the coating of the soft plastic or the like is peeled off, the gel-like primary coat is further wiped and cleaned by a polishing operation. Is required.

A conventional apparatus used for this kind of polishing operation is disclosed, for example, in Japanese Patent Application Laid-Open No. 64-11756. As shown in FIGS. 9A and 9B, this polishing apparatus includes four thread-like polishing members 102, 102, 102, 1 inside a cylindrical rotating body 101.
02, the wire 103 is inserted between them, and only the rotating body 101 and the thread-like polishing members 102, 102, 102, 102 are rotated in a state where the wire 103 is fixed, so that the primary coat on the outer peripheral surface of the wire 103 is formed. To wipe it off. Thread-like polishing members 102, 102, 102, 10
Numeral 2 is wound around a winding bobbin (not shown) while being rotated together with the rotating body 101 and fed in the axial direction of the wire 103 to polish and clean the outer peripheral surface of the wire 103 without gaps. In the drawing of the polishing apparatus of FIG. 9, (A) is a cross section, and (B) of FIG.
Is a longitudinal sectional view.

[0004]

However, according to this conventional polishing apparatus, the four thread-like polishing members 102, 102, 102,
Since the operator has to insert and reciprocate the thin and brittle optical fiber 103, the optical fiber 103 may be broken if not carefully performed, resulting in poor workability. Further, according to the apparatus, a dedicated thick thread is used as the thread-like polishing member 102, and a total of eight bobbins are required for each of four bobbins, so that a space is required. In addition, since the polishing operation is performed while rotating the polishing member 102 around the wire rod 103 and extending it in the axial direction, the amount of the polishing member 102 used increases, which is uneconomical and requires frequent replacement of the bobbin. . Further, in the case of the conventional apparatus, the use amount of the cleaning alcohol increases with the use amount of the polishing member 102 per unit work amount, so that it is uneconomical and odor is a problem.

The rotating body 101 and the thread-like polishing member 10
Since the torsion moment is easily applied to the wire 103 by the rotation of the wire 2, the wire 10 such as an optical fiber,
In the case of No. 3, wire 1 is used to prevent torsional moment.
03, the contact pressure of the threadlike polishing member 102 must be set as small as possible. Therefore, a sufficient polishing effect cannot be obtained due to insufficient contact pressure.

Further, when the outer diameter of the wire 103 to be polished changes, the size of the hole 104 of the rotating body 101 must be changed, so that the wire 103 having various outer diameters cannot be used in a wide range.

An object of the present invention is to provide a device which allows easy insertion of a wire, reduces the use of a thread-like polishing member as much as possible, and can be used without changing equipment even when the thickness of the wire changes. Aim.

[0008]

In order to achieve the above object, a wire polishing apparatus according to the present invention comprises a wire chuck for holding a wire and detachably attaching the wire to a main body of the device, a thread-like polishing member, and a wire-like polishing member. A guide portion around which a thread-like polishing member is stretched along the wire, a delivery member for sending the thread-like polishing member to the guide portion by a predetermined length, and a rotation only when the thread-like polishing member is wound up A winding member that rotates around the wire rod to give a twist to the thread-like polishing member; a moving unit that moves the rotating member in the axial direction of the wire rod ; Axial direction of wire
When the wire-like polishing member is wound on the wire rod
A tension that gives an almost constant tension stronger than when attaching
And one of the sending member and the winding member is fixed to the apparatus main body, and the other is movable in the axial direction of the wire together with the rotating member. By rotating around the wire, the thread-like polishing member is wound around the outer periphery of the wire, and the outer periphery of the wire is tensioned by moving the rotating member in the axial direction. I try to polish.

Further, the wire rod polishing apparatus of the present invention is provided with a device for supplying an organic solvent to the thread-like polishing member, and discharges a predetermined amount of the organic solvent to the thread-like polishing member.

[0010] In the wire polishing apparatus of the present invention, a laser outer diameter measuring device for measuring the diameter of the wire is provided.

[0011]

Therefore, when the wire held by the wire chuck is fixed to the apparatus main body, and then the rotating member is moved closer to the wire and then rotated about the wire, the wire is guided by the rotating member, and the wire is guided around the wire. A thread-like polishing member arranged along the wire is entangled with the wire and wound with a certain tension. Then, when the rotating member moves away from the wire, the thread-like polishing member moves in the axial direction on the wire with tension applied. At this time, the thread-like polishing member and the wire member are fixed without substantially changing the path length of the thread-like polishing member by swinging of the tension portion because the thread-like polishing member has the delivery member and the winding member fixed. Is moved without changing the relationship, a substantially constant tension is applied stronger than when the wire is wound, and the outer surface of the wire is wiped in the axial direction. Since the thread-like polishing member is substantially wound at least one round or more around the outer peripheral surface of the wire at a predetermined contact pressure, the outer peripheral surface of the wire is polished without gaps and impurities adhered to the surface, such as a primary coat material, are removed. Remove.

When the wire member 1 is fed to the guide portion 6 by a length, the winding member 8 for winding up the used thread-like polishing member 5, and when the wire member 1 is wound around the thread-like polishing member 5 when the rotating member 3 moves. A tension unit 9 for applying a substantially constant tension (tensile force), an alcohol supply unit 10 for supplying an organic solvent such as cleaning alcohol to the thread-like polishing member 5, and a device main body 57 for supporting the same. I have. This wire rod polishing device is provided in a vertical type so that a wire rod 1 to be processed, for example, an optical fiber is arranged in a vertical direction, and a turning member 3 is turned around a wire rod chuck 2 so that a thread-shaped polishing member is turned. 5 is wrapped around the outer periphery of the wire 1, that is, the core wire 1 a from which the coating is removed, and wound around the wire 1 with a thread-like polishing member 5 to which tension is given by axial movement or lowering of the rotating member 3. I have.
In this case, polishing can be performed without bending the core wire 1a of the optical fiber 1 due to gravity, and dust and the like adhered to the polishing member 5 can easily fall, and cleaning can be reliably performed.

In the present embodiment, the wire chuck 2 includes a chuck 11 for holding the optical fiber 1 as a wire and a chuck holder 12 for holding the chuck 11 . As the chuck 11 , although not particularly limited, for example, a collet chuck is used. The chuck 11 is attached to a coating portion at the tip of the optical fiber 1 and is used commonly in a coating stripping process which is a pre-process of the polishing process or a ferrule mounting process which is a post-process. On the other hand, the chuck holder 12 is capable of fixing the wire 1 at a predetermined position only by inserting the chuck 11 , for example, a spring is built in and fixed by fitting a ball provided with this spring force and a concave portion. Fixing means 58 is employed. In this case, chuck 1

A ball (not shown) is fitted into the
11 is provided so as to be separated when pulled.

The rotating member 3 twists the thread-like polishing member 5 and entangles the core wire 1a of the wire 1. The conical shape enables the wire 1 to be processed to be inserted into the center thereof. A through hole 13 having a guide portion is provided, and a required number of guide holes 14 for passing the thread-like polishing member 5 around the through hole 13 are provided, for example, two in the present embodiment. The rotating member 3 is a support 3 that constitutes the moving means 4.

The rotating member 3 is provided so as to be able to rotate by an arbitrary angle by a motor 16 mounted on the moving means 4. The rotation of the motor 16 is transmitted to the rotating member 3 via the gear 15. The rotation member 3 is set such that the angle at which the thread-like polishing member 5 is wound around the wire 1 is substantially one or more turns. For example, in the case of the present embodiment, since the two thread-like polishing members 5, 5 are arranged symmetrically, each of the thread-like polishing members 5, 5 comes into contact with the wire 1 within a range of 180 ° or more. It is only necessary to rotate so that it is twisted between the upper guide pulleys 17 and 17 as described above. Therefore, it is most preferable that the rotation angle of the rotating member 3 be about 360 °. When the two thread-like polishing members 5 and 5 are used at 360 ° or less, it may not be possible to completely wind the entire circumference of the optical fiber 1 without a gap, and at 360 ° or more, it may be wound a few times. The tightening becomes too tight, and cleaning cannot be performed smoothly.

The guide portion 6 stretches the thread-like polishing members 5, 5 unreeled from the delivery member 7 around the wire 1 (particularly, the core wire 1 a) along the wire 1, and then guides the thread-like polishing members 5 to the rotating member 3, and winds them. In the case of the present embodiment, guide pulleys (hereinafter referred to as upper guide pulleys) 17 and 17 provided above the rotating member 3, the bobbin 30 of the winding member 8, and And the guide hole 14 of the rotating member 3 between the two.

The path length is provided so that it can be changed. Upper guide pulley 17, 17
The lower guide pulleys 18 and 18 are attached to the moving means 4 and are fixed at the same position regardless of the rotation of the rotating member 3. Therefore, the thread-like polishing member 5 is connected to the delivery bobbin 2.
After removal from 0, subjected to tension arm 24 of the tension section 9 via the guide rod 19, it is further subjected to a lower guide pulley 18 and the upper guide pulley 17, the guide hole 14 of the rotating member 3 After passing through, it is wound on the winding bobbin 30 . Then, when the rotating member 3 is rotated, the thread-like polishing members 5, 5 suspended from the upper guide pulleys 17, 17 are wound around the wire 1 so as to be entangled with the twisted wire 1.

20 ) and a brake mechanism 21. When the thread-like polishing member 5 is fed, that is, when it is not wound by the winding member 8, for example, when the rotating member 3 is polished by descending, its rotation is fixed. Is done. Delivery bobbin 2
No. 0 is required for the number of the thread-like polishing members 5, and in this embodiment, two are provided. The delivery bobbin 20 is fixed by, for example, pressing a wedge-shaped brake piece 21a inserted between the pair of delivery bobbins 20 , 20 by a spring 21c and fixing the same by frictional force.
Therefore, when the brake piece 21a is retracted by energizing the solenoid 21b, the delivery bobbin 20 is rotated by the movement of the rotating member 3 or the rotation of the winding bobbin 30 , and the thread-like polishing member 5 is paid out. As the material of the brake piece 21a and the member on the side of the delivery bobbin 20 that comes into contact with the brake piece 21a, for example, steel is used to impart durability.

And a tension spring 22 for applying tension to the arm 24. When the tension acts on the thread-like polishing member 5, the tension spring 22 is extended to maintain a constant tension acting on the thread-like polishing member 5. . The tension spring 22 attached to the tip of the tension arm 24 is connected to the apparatus main body 57 via the balance arm 23.
Suspended. The center of the balance arm 23 is rotatably attached to the main body 57 , and the tension springs 22 are attached to both ends. For this reason, when one of the thread-like polishing members 5 and 5 has a strong (or weak) tension, the balance arm 23 functions to tilt and provide the same tension. By the swing of the tension arm 24, the thread-like polishing members 5, 5 are formed.
Of the thread-like polishing member 5,
It operates so that a substantially constant tension can be applied to the thread-like polishing members 5 and 5 stronger than when the wire 5 is wound without being newly unwound. In this case, at the time of the polishing operation, the thread-like polishing members 5 and 5 wound around the optical fiber 1 as the wire do not move in the circumferential direction of the wire 1 but move only in the axial direction, so that the wire 1 is not twisted. . The sending member 7 is rotatably supported by being fitted to a support shaft 39b rotatably mounted on a bracket 38 protruding from the apparatus main body 57 via a bearing 39a.

Thus, the outer diameter of the optical fiber is measured. On the front surface of the light emitting side device 40a, a shielding plate 42 having a laser scanning hole 41 for regulating the width of laser scanning is fixed to and suspended from the device main body 57. The shielding plate 42 contacts the tension arm 24 at its lower end, and regulates the upward movement of the tension arm 24. Further, a proximity switch 43 for detecting the approach of the tension arm 24, that is, the contact of the tension arm 24 with the shield plate 42, is installed on the shield plate 42.

The apparatus 10 for supplying an organic solvent such as alcohol to the thread-like polishing member 5 includes an alcohol tank 44, a pump 45 for taking out and supplying a required amount of alcohol from the alcohol tank 44, and an upper guide for alcohol. An alcohol discharge port 46 for jetting from the vicinity of the pulleys 17 and 17 to the thread-like polishing members 5 and 5 and a pipe 47 for supplying alcohol to the alcohol discharge port 46 are provided. The alcohol discharge port 46 is supported by a support plate 48

Here, as the organic solvent for cleaning the polishing member 5 filamentous, although in the present embodiment the alcohol is exemplified, but the invention is not limited thereto, trichlorethylene, acetone, full <br/> Les O Can also be used. The pump 45
Is driven by a solenoid 62.

As the thread-like polishing member 5, it is preferable to use a cotton thread. However, the present invention is not particularly limited to this, and any member having a water-absorbing property for supplying cleaning alcohol to the wire can be used. . The polishing member 5 is moved from the delivery member (bobbin 20) 7 to the guide rod 19 → the tension arm 24.
→ The guide pulley 18 on the lower side of the moving means → the guide pulley 17 on the upper side of the moving member → extends through the guide hole 14 of the rotating member 3 to the winding member (bobbin 30) 8. Note that reference numeral 4
Reference numerals 9 and 50 denote proximity switches for detecting the movement of the crank 31 constituting the moving means 4, 51 a proximity switch for detecting the movement of the brake piece 21 a constituting the delivery member 7, and 52 a pump 45 constituting the alcohol supply device 10. , 53 is a proximity switch for detecting the rotation of the rotating member 3, and 54 is a proximity switch for detecting the movement of the rocker plate 29 constituting the winding member 8.
In this embodiment, the members constituting the wire rod polishing apparatus are controlled by one control means 55 as shown in FIG. 8, and it is determined whether or not the operation of each constituent member is reliably executed. It is detected by the proximity sensors 43, 49, 50, 51, 52, 53.

With the above configuration, the outer peripheral surface of the wire is polished as follows.

First, a wire to be polished, for example, the optical fiber 1 is set on the chuck holder 12 of the apparatus main body 57 for each chuck 11 . Device body 57 of optical fiber 1
The attachment to the device is performed manually or automatically. Optical fiber 1
Is a state in which a coating portion such as a soft plastic is removed in a previous step, and silicon or the like for coating is adhered to the outer peripheral surface of the optical fiber 1. At this time, the portion of the optical fiber 1 from which the coating has been stripped is projected downward by an appropriate amount and fixed. In the preparation stage, the thread-like polishing member 5
Is the delivery bobbin 20 → guide rod 19 → tension arm 24 → lower guide pulley 18 → upper guide pulley 17 →
The rotating member 3 (guide hole 14) is stretched over the winding bobbin 30 and is arranged around the wire 1 so as to be substantially symmetrical with the wire 1 as a symmetric axis.

Thereafter, a start switch (input means) 5
6 is turned on and a control signal is sent from the control means 55 to the motor 34 which is a driving source of the moving means 4.
The motor 34 is rotated to apply a vertical displacement from the crank 31 to the cam follower 32 to raise the rotating member 3, the upper and lower guide pulleys 17, 18 and the winding member 8 on the cam follower 32. The rising of the rotating member 3 is performed by the proximity sensor 4.
At step 9, the rotation of the motor 34 is stopped to reach the predetermined position, and the moving means 4 is stopped.

Next, the solenoid 21b is driven by the control signal from the control means 55, the brake piece 21a is raised, and the delivery bobbin 20 is made rotatable. Further, the solenoid 25 is driven by a signal from the control means 55 to rotate the winding bobbin 30, and the winding of the thread-like polishing member 5 is started.

At the same time, the solenoid 21b is driven by a signal from the control means 55, and the brake piece 21a descends to come into contact with both sides of the delivery bobbins 20 on both sides.
Is fixed. Further, the movement of the rocker plate 29 is detected by the proximity sensor 54, and the suction of the solenoid 25 is stopped. The return spring 26 returns the rocker plate 29 to the original position and fixes the winding bobbin 30. Then, the pump 45 is driven by the control means 55, and a predetermined amount of alcohol is discharged from near the upper guide pulleys 17, 17 and drips on the respective thread-like polishing members 5, 5.

Thereafter, the control means 55 controls the motor 16.
Is driven to rotate the rotating member 3 forward by 360 °, so that the polishing member 5 is entangled with the wire 1. This gives 2
The polishing members 5 and 5 intersect at the position of the wire 1 and are wound around the outer peripheral surface of the wire 1 by half or more. The proximity sensor 53 detects whether the rotation has been performed by a predetermined amount.
When the rotating member 3 rotates forward, the fiber-like polishing members 5 and 5 are entangled with the optical fiber 1 and are wound around the wire 1. As a result, the wire 1 is stably held by the polishing members 5, 5 in a crossing-like state from all directions. At this time, these polishing members 5 and 5 come into contact with the outer peripheral surface of the wire 1 at a predetermined contact pressure. This contact pressure is given before and after the rotation of the rotating member 3 by increasing the extending path of the polishing members 5, 5, and can be set to an appropriate value by increasing the amount of rotation of the rotating member 3.

Next, the motor 34 is driven by a signal from the control means 55, and the rotating member 3 is lowered by the rotation of the crank 31. The rotation of the crank 31 drives the cam follower 32, and the moving means 4 and thus the rotating member 3
Is lowered. During this movement, the thread-like polishing member 5 moves the winding position with respect to the wire 1 along with the movement of the rotating member 3 to remove silicon and the like adhered to the outer peripheral surface of the wire 1 and clean the surface thereof cleanly. . At this time,
Since the sending member 7 and the winding member 8 are fixed to the thread-like polishing member 5, the tension arm 24 of the tension portion 9 is used.
The outer surface of the wire 1 is wiped in the axial direction while applying a substantially constant tension stronger than when wound around the wire 1 without substantially changing the path length of the thread-like polishing member 5 due to the rocking. Since the thread-like polishing member 5 is substantially wound at least one round around the outer peripheral surface of the wire 1 at a predetermined contact pressure, the outer peripheral surface of the wire 1 is polished without gaps and the primary coat material or the like adhered to the surface. Is removed. During this movement, the polishing member 5 moves to the tip of the core wire 1a and comes off, whereby polishing is completed, and further moves and stops. When the rotating member 3 reaches the lower moving end, the rotating member 3 rotates the motor 16 in response to a signal from the control means 55, and the rotating member 3 is rotated in the reverse direction, that is, in the rewinding direction, and is rotated by 360 °. The member 5 returns to the initial position and is substantially parallel to the wire 1. The proximity sensor 53 detects whether this rotation is performed normally.

Such a polishing operation is performed once or several times as necessary to completely polish the outer peripheral surface of the wire 1. After the polishing is completed, the wire 1 measures the diameter of the optical fiber using the fiber diameter measuring device 40.
This is performed in order to search for a ferrule having a hole diameter closest to the outer diameter of the optical fiber in order to fix the optical fiber 1 to the ferrule in the next step. Thereafter, the wire 1 together with the chuck 11 is removed from the chuck holder 12 of the apparatus main body 57, and is assembled into a ferrule or the like in the next step.

The above embodiment is a preferred embodiment of the present invention, but the present invention is not limited to this embodiment, and various modifications can be made without departing from the gist of the present invention. For example, the number of the thread-like polishing members 5 may be plural, and may be three or more. Further, in the apparatus of this embodiment, a stepping motor or a solenoid is used as a drive source for each member, but a cam, an air cylinder, or the like may be used instead. Further, a combination of the crank 31 and the cam follower 32 is used as a drive source of the moving means 4, but the present invention is not particularly limited thereto. Any mechanism that drives the means can be implemented. Further, in the present embodiment, the sending member 7 is fixed to the apparatus main body 57 and the winding member 8 is provided so as to move together with the moving means 4. However, the present invention is not particularly limited to this. The take-up member 8 side may be fixed to the apparatus main body 57 by being placed and movable. Further, by automatically attaching and detaching the wire rod 1 to be processed, the polishing processing by the present apparatus can be completely unmanned. Further, in this embodiment, after the thread-like polishing member 5 coming out of the delivery member 7 has passed through the tension arm 24, the thread-like polishing member 5 is once directed downward, and then changes its direction upward at the lower guide pulley 18. Alternatively, the tension may be supplied directly from the tension arm 24 to the upper guide pulley 17.

As apparent from the above description, milling-out equipment of the wire of the present invention, either one of the delivery member and the winding member wound with polished member filamentous fixed to the apparatus main body, The other is provided so as to move together with the rotating member that applies twist to the thread-like polishing member, and a tension portion that keeps the tension of the thread-like polishing member constant between them is provided, so that the wire-like polishing member is wound around the wire. Although not very strong tension is applied, when the surface of the wire is polished with the movement of the rotating member, it is provided so that a stronger and almost constant tension is applied to the end by the action of the tension part as compared to when it is wound around the thread-like polishing member. As a result, the wire is wiped in the axial direction while holding the wire at a uniform and strong contact pressure, thereby effectively removing impurities such as the primary coat material adhering to the outer peripheral surface of the wire. It can be.

Further, since the apparatus of the present invention performs the polishing work at the same place of the thread-like polishing member, the use amount of the thread-like polishing member is small, and it is not necessary to frequently replace the bobbin, and the cost can be reduced. In addition, the amount of alcohol used is reduced and the problem of odor is eliminated.

Furthermore, since the polishing member does not rotate during the polishing operation, no torsional moment is generated in the wire, and the polishing operation proceeds without deformation of the material.

In the polishing apparatus of the present invention, a wire is inserted between thread-like polishing members arranged at relatively wide intervals, and the thread-like polishing member is entangled with the wire by rotation of the rotating member. Since the wire is wound with a constant tension, the work of inserting the wire is easy, the tip of the wire is not bent and bent, and even if the diameter of the wire changes, the polishing member contacts. changes in the length and some of the tension does not become unable to work me Oh just cause.
