Description

  The present invention relates to an apparatus in which another linear body is wound around a core wire, for example, a device that disassembles and separates concentric wires such as electric wires, and more specifically, in order to smoothly disassemble the concentric wires, The present invention relates to a guide member attached to the apparatus.

  Recycling of industrial products, that is, recovery of usable resources from discarded products for effective use is requested for various products in order to save resources or deal with environmental problems. There is no exception to electric wires, and recycling of collected used wires is an important issue when replacing wires that have reached the end of their useful lives. Recycling of electric wires is actually carried out in various forms, and technology is being actively developed to disassemble the collected electric wires and sort them by material for efficient recycling.

  Steel core aluminum strands (ACSR) commonly used for high-voltage power transmission lines consist of a number of aluminum wires twisted around a steel core wire. In such an electric wire, in order to separate the collected spent steel core aluminum wires for recycling, as disclosed in Japanese Patent Application Laid-Open No. 2002-1000025, for example, the electric wire is finely cut and cut. There is a method of separating an aluminum wire and a steel wire by applying vibration or the like to the electric wire. As a result, the strands are separated, and it is possible to separate and collect the steel wire and the aluminum wire using an electromagnet. The separation cost is relatively low, and high-value aluminum is mixed with impurities. It can collect | recover in the state which hardly has.

  Among the electric wires, there is an electric wire called an optical fiber composite ground wire (hereinafter referred to as “OPGW”) in which an optical fiber for communication is built in a core wire and an aluminum-coated steel wire or the like is wound around. The OPGW is used, for example, as a lightning protection wire laid at the top of a steel tower of a high-voltage power transmission line. By laying this, the power transmission system for energy transmission is also used for information communication. . As shown in FIG. 13, an aluminum tube accommodating an optical fiber is arranged as a core wire in the center of the OPGW, and eight steel wires (linear bodies) coated with aluminum are surrounded by stranded wires. It is surrounded. A grooved aluminum wire with three U-shaped grooves is inserted in the aluminum tube, and each U-shaped groove has a multi-core optical fiber cable such as three or six cores. It is stored. Among OPGWs, there are those in which aluminum-coated steel wires are wound in multiple layers, those in which steel wires and aluminum wires are wound in multiple layers, or those that do not have grooved aluminum wires. As for such OPGWs, those that have reached the end of their useful lives will be collected for replacement with new OPGWs.

  In order to recycle the recovered OPGW, it is necessary to separate the central aluminum tube or grooved aluminum wire from the surrounding aluminum-coated steel wire and take it out. However, when the OPGW is cut finely by adopting a method as shown in the above patent document, the optical fiber accommodated in the central aluminum tube or the like is cut finely at the same time, and the aluminum tube or the like separated in that state Will remain inside. It is impossible to efficiently separate an optical fiber from an enormous number of aluminum tubes or the like cut in a short length, and it is very difficult to extract aluminum having high resource value without impurities. Therefore, in reality, the collected OPGW must be discarded as industrial waste.

Based on these circumstances, the present applicant disassembles the concentric wires such as OPGW and separates the central aluminum tube and the like from the aluminum-coated steel wire wound around the device without cutting the compact and simple device. Was previously filed as Japanese Patent Application No. 2005-68490. In this dismantling and separating apparatus, two rotating bodies are installed in the front and rear, and a stationary winding mechanism that is pivotally supported by the two rotating bodies is disposed therebetween. The number of guide tubes equal to the number of linear bodies wound around concentric wires is stretched around the outer periphery of the two rotating bodies, and the linear bodies are guided rearwardly through this. The two rotating bodies are rotationally driven in a direction opposite to the winding direction of the linear body, whereby the linear body is rewound and the central core wire can be wound around the winding mechanism. When the concentric strand is OPGW, the aluminum tube of the core wire can be taken out as it is, and the optical fiber is separated by cutting the taken-out aluminum tube in the longitudinal direction or by pulling out the optical fiber. Can be easily separated without impurities.
That is, this disassembly / separation apparatus can disassemble and collect the core wire and the linear body as they are, and is an apparatus that is the basis of the present invention. Therefore, the disassembly / separation apparatus is based on FIGS. 7 to 11. The operation when sorting the OPGW and the OPGW will be described in detail.

  As shown in the overall view of FIG. 7, the dismantling and separating apparatus 1 developed by the present applicant includes a first rotating body 10 and a second rotating body 20 for disassembling the OPGW, and an aluminum which is a core wire between them. A winding mechanism 30 for winding the tube is arranged. Around the take-up mechanism 30, a plurality of guide tubes 4 through which each of the steel wires (linear bodies) around the unwound OPGW pass are arranged, and after passing through the steel wires, the second rotating body 20 is reached. The guide tube 4 is not limited to the one having a completely circular cross section, and a tube having a notch in part, that is, a tube having a slit formed in the axial direction can also be used. The used OPGW to be disassembled is supplied to the first rotating body 10 from the left side of FIG. 6, that is, from the front side of the disassembling and separating apparatus 1, and the separated steel wire is converged behind the second rotating body 20 and disassembled. Sent from the sorting device.

  As shown in FIG. 8, the first rotating body 10 is formed by connecting a disk body 11 on which an outer peripheral gear 12 is formed and a bearing portion 13 in front of the disk body 11 with a hollow shaft 14. The disc body 11 is the maximum diameter portion of the first rotating body 10, and the guide tube 4 is attached to the outer peripheral portion. Further, on both sides of the outer peripheral gear 12, flat circular portions 15 that support a load such as a winding mechanism 30 that acts on the first rotating body 10 are formed. Around the disk body 11, four rollers 70 and 80 that are pivotally supported by the frame body 60 shown in FIG. 9 are arranged, and the flat circular portion 15 of the disk body 11 comes into contact with these rollers. Then, the rotating body 10 is supported. One of the four rollers is a driving roller 70 for rotating the rotating body 10 and includes a driving gear meshing with the outer peripheral gear 12 (in FIG. 7, a part of the frame 60 and the driving roller). 70 only).

  A bearing portion 13 is fixed to the front end of the hollow shaft 14 of the first rotating body 10, and the bearing portion 13 is supported by being fitted into a bearing 53 placed on the rear side of the front frame 51. As described above, the first rotating body 10 is supported by the rollers 70 and 80 at the rear and the bearing 53 at the front, and is rotatable. The bearing 13 has a space 18 through which a steel wire passes, and a guide plate 19 is attached in front of the space 18. As shown in FIG. 10, the guide plate 19 has a hole 191 through which an aluminum tube passes at the center, and holes 192 corresponding to the number of OPGW steel wires to be disassembled.

  A second rotating body 20 having the same structure as the first rotating body 10 is disposed in the rear part of the dismantling and separating apparatus 1 with the front-rear direction reversed. That is, in the second rotating body 20, a disc body 21 having a guide tube 4 fixed to the periphery thereof and having an outer peripheral gear 22 is provided on the front side of the sorting device, and a bearing connected by a hollow shaft 24 on the rear side thereof. Part 23 is installed. A guide tube 4 is stretched between the disk body 11 and the disk body 21, and both rotating bodies are connected from a shaft 55 through a transmission device 57 such as a chain and a toothed belt, and a drive roller 70. The drive motor 56 is rotationally driven in a direction opposite to the winding direction of the steel wire wound outside the OPGW.

  A winding mechanism 30 is disposed between the first rotating body 10 and the second rotating body 20, and the winding mechanism 30 includes a winding device for winding an aluminum tube that is a core wire. The winding mechanism 30 has a frame 31, and a hollow support shaft 32 (see FIG. 8) is integrally provided at the front end and the rear end of the frame 31, and these are the first rotating body 10 and the second rotating body 20. The disc bodies 11 and 21 are respectively fitted into bearings press-fitted into the hub portions. That is, the take-up mechanism 30 is suspended from the central parts of the disc bodies 11 and 21. Mounted on the frame 31 is a winding device comprising a core winding drum 33 rotated by a drive motor 34, a traverse mechanism 43 for uniformly winding the core wire around the winding drum 33, a fixed guide roller 42, and the like. ing.

  In order to separate the OPGW by operating the dismantling and separating apparatus 1, the OPGW to be disassembled is passed through the hollow tube 61, and then manually unraveled to a predetermined length, and the aluminum tube as the core wire and a plurality of outer peripheral steel wires To separate. The separated aluminum pipe of OPGW passes through the hole 191 of the guide plate 19 and the hollow shaft 14 of the first rotating body 10 as shown by the solid line X in FIG. 7, and further, the fixed guide roller 42 of the winding mechanism 30. And it passes between the rollers of the traverse mechanism 43 and is wound around the core winding drum 33.

  On the other hand, as shown by the broken line Y in FIG. 7, the plurality of steel wires are spread outward immediately after the hollow tube 61, and each steel wire is passed through the hole 192 of the guide plate 19, and then the first rotating body. 10 passes through the hollow portion 18 formed in the bearing portion 13 and is inserted into the guide tube 4 attached to the peripheral portion of the disk body 11. Further, the steel wire is passed through the guide tube 4 and sent to the disc body 22 of the second rotating body 20, and here, the steel wires are converged toward the rear in a manner opposite to that of the first rotating body 10. The assembled steel wire passes through the hollow tube 62 at the rear end of the sorting device 1 and is wound around a steel wire winding drum (see FIG. 11). Since the steel wire is originally processed so as to be “twisted”, when it is assembled, it automatically returns to the original OPGW form and can be easily wound.

  After making the above preparations, OPGW is continuously fed from the hollow tube 61, and at the same time, the rotating body drive motor 56 is driven to transmit the transmission mechanism such as the shaft 55, the toothed belt transmission 57, the drive roller 70, and the like. Thus, the first rotating body 10 and the second rotating body 20 are rotated in synchronization with the direction opposite to the winding direction of the steel wire. Further, the motor 34 of the winding mechanism 30 is driven, the core winding drum 33 is rotated, and the traverse mechanism 43 is operated. The rotation of both the rotating bodies 10 and 20 unwinds the OPGW steel wire, and the aluminum tube passes through the center of the first rotating body 10 and is uniformly wound around the core winding drum 33.

In this way, the dismantling and separating apparatus 1 developed by the applicant of the present application has two rotating bodies at the front and rear, which are opposite to the winding direction of the linear body wound around the concentric wire. The core wire and the linear body are separated and collected while rotating and breaking the concentric wire. Therefore, the processing work for recycling becomes easy, and the core wire and the linear body can be regenerated by separate processing steps, and efficient recycling can be achieved.
Incidentally, a device for revolving a linear body such as a tape wound around an electric wire in a direction opposite to the winding direction and winding it on a rotating bobbin is disclosed in Japanese Utility Model Publication No. 58-36510. . However, the steel wire of OPGW has much larger specific gravity and higher rigidity than the tape, and to wind it on a bobbin using such a device requires a very large device with a large required power. The dismantling and separating device 1 is a compact and simple device. Bring the device of the present invention to a site where OPGW is collected from the tower of the high-voltage power transmission line, and disassemble the OPGW and separate the aluminum pipes etc. at or near the construction site. can do. At this time, as shown in FIG. 11, for example, the overhead wire winch is installed in front of the dismantling and separating apparatus 1 and the steel wire winding drum is installed in the rear, and the OPGW is pulled by the overhead wire winch and sent to the dismantling and separating apparatus 1. The converged steel wire after taking out the core wire can be wound on a steel wire winding drum.

  The dismantling and separating apparatus developed by the present applicant is a concentric unit fed from the front, the linear body wound around the outer periphery of the wire is unwound by rotating the two rotating bodies in the direction opposite to the winding direction, The line is dismantled. The concentric strands are pulled by an overhead wire winch, for example, and sent to the dismantling / separating device. In order to dismantle them continuously and perform the work in an appropriate state, the number of rotations per unit time of the two rotating bodies is set. It is necessary to match the number of windings of the linear body wound around the concentric wire to be disassembled at that time. When a concentric wire is supplied to the dismantling and separating apparatus at a constant feed speed, the rotary body is driven at a rotation speed (rpm) equal to (feed speed (m / min.) × number of turns n per 1 m). .

  By the way, for concentric strands such as OPGW, the number of turns of the unit length of the linear body wound around the outer periphery is not uniform due to variations in the manufacturing process, deformation of the line due to secular change, and the like. Even if the number of windings is not so great, when the speed of wire feed is increased from the concentricity for disassembly separation, the amount of unevenness is accumulated and hinders smooth dismantling work.

  For example, a guide plate 19 is provided at the front portion of the rotating body 10 of the dismantling and separating apparatus 1, and each of the linear bodies Y wound around the outer periphery passes through the hole 192 of the guide plate 19 to the rear guide tube 4. The concentric strands are configured to be guided, and unraveling starts at a position in front of the guide plate 19. The “unwinding position” is constant at the set position shown in the left figure when the number of turns of the rotating body 10 is constant, as shown in FIG. When the place where the number of windings is increased is sent in, the unwinding is not in time and the “unwinding position” approaches the guide plate 19 as shown in the center figure. As shown in FIG. When the “unwinding position” approaches the guide plate 19, the bending of the linear body becomes strong, and the resistance when sending the wire from the concentricity increases. In extreme cases, the feeding becomes impossible, and when the wire is moved away, the unraveling is performed. There is a risk that the linear bodies will become tangled with each other.

In order to eliminate the trouble caused by the non-uniformity of the number of windings, a device that rotates in accordance with the number of windings (twisting) of the concentric wires is installed in front to detect the number of windings. It is conceivable to control the number of rotations according to the number of turns. However, the rotating body 10 rotates integrally with the rotating body 20 and is accompanied by various devices, so that the weight and the moment of inertia are large, and the rotation of the rotating body is adjusted by a method such as adjusting the rotational speed of the drive motor 56. It is actually difficult to control the number with good responsiveness.
The object of the present invention is to disassemble the wire from the concentricity, so that the linear body is guided backward through the rotating body rotating in the direction opposite to the winding direction of the linear body wound on the outer periphery, and the linear body is rewound. An object of the present invention is to remove an obstacle caused by non-uniformity of the number of windings with a simple structure in a dismantling / separating apparatus for taking out the central core wire, and to enable efficient and smooth dismantling work.

In view of the above-described problems, the present invention provides a feed device that is provided with a guide member having a conical portion tapered toward the front and attached with a constant torque clutch at the front portion of the first rotating body. Thus, by feeding concentric wires to the apparatus, the malfunction of the dismantling and separating apparatus due to the non-uniformity of the number of windings is eliminated. That is, the present invention
"A device that disassembles and separates wires from concentric cores around which a plurality of linear bodies are wound,
A first rotating body that is rotatably supported and includes a center hole through which the core wire passes in the center, and a plurality of guide tubes through which the linear body passes is disposed in the periphery. A plurality of the guide tubes through which the linear body passes are attached to the part, and a second rotating body that is rotatably supported is disposed rearward,
A winding mechanism pivotally supported by the first rotating body and the second rotating body in a stationary state is disposed between the first rotating body and the second rotating body;
A center hole through which the core wire passes is formed at the center of the front part of the first rotating body, and a plurality of holes through which the linear body passes are formed at the periphery, and tapered forward. A guide member formed with a cone-shaped part is attached,
While the first rotating body and the second rotating body are rotated in synchronization with the direction opposite to the winding direction of the linear body, the concentric strands are moved by the feeding device equipped with a constant torque clutch. By feeding from the front of the one rotating body, the core wire is wound around the winding mechanism, and the linear body is converged to the rear of the second rotating body and wound.
This is a dismantling and separating apparatus characterized by this.

  According to a second aspect of the present invention, the feeding device may be a reel winder that is installed behind the second rotating body and winds up while pulling the linear body. Further, as described in claim 3, a feeding device that is installed in front of the first rotating body and feeds a wire from the concentricity may be used.

  According to a fourth aspect of the present invention, the guide member includes a disc in which the plurality of holes are formed, and a conical part in which the center hole and the conical portion are formed, and the disc It is preferable that the cone part is connected. In this case, in order to detect the cutting of the linear body, the disc in which the plurality of holes are formed is coupled to the first rotating body via an insulating material as described in claim 5. A plurality of holes in the disc are covered with an insulating material, and a low voltage is applied between the concentric strands fed into the first rotating body and the disc of the guide member, And the detection means which detects the presence or absence of the electric current which flows between both can be provided.

  According to a sixth aspect of the present invention, a vacuum suction device can be installed in the vicinity of the guide member.

  The disassembly and separation apparatus according to the present invention is particularly suitable for disassembling and separating an optical fiber composite ground wire, that is, an OPGW, whose core is an aluminum tube containing an optical fiber, as described in claim 7. .

  The dismantling and separating apparatus developed by the present applicant, which is the basis of the present invention, includes two rotating bodies that rotate in the opposite direction to the winding direction of the linear body, and a stationary winding mechanism that is pivotally supported by the rotating bodies. This is a device for taking out the core wire while rewinding the linear body. That is, since the core wire and the linear body can be taken out as they are, the processing work for recycling becomes easy and efficient recycling can be achieved.

In the dismantling and separating apparatus according to the present invention, a feeding device equipped with a constant torque clutch is arranged, and a concentric wire is fed to the device by a constant tension or the like, and the wound linear body is unwound and the guide tube Attach the guide member to the place where it is introduced. The guide member is formed with a plurality of holes through which the linear body passes in the periphery, and is provided with a conical portion that tapers forward, and the linear body is a conical portion of the guide member. And is guided to a guide tube that passes through a plurality of holes in the peripheral portion and is fixed to the first rotating body. Therefore, the spread angle when the linear bodies are rewound is accurately controlled, and the linear bodies are prevented from being entangled at the rear part of the “unwinding position”, so that the disassembling operation becomes very smooth.
As the feeding device equipped with the constant torque clutch, the reel winder of the invention of claim 2 and the feeding device of the invention of claim 3 can be used. When the linear body is pulled and fed from the rear of the apparatus using a reel winder, the linear body does not bend even if the feeding speed is increased, and higher-speed dismantling work is possible.

  As described above, a linear body wound around a concentric wire to be disassembled has a nonuniformity in the number of windings per unit length, and is wound in a state where the rotating body is driven at a constant rotational speed. When dismantling a large number of parts, the “unwinding position” moves backward. In the present invention, the guide member is provided with a tapered cone-shaped portion, and the concentric strands fed by a reel winder or the like are unraveled by the linear body contacting the tip of the cone-shaped portion. The linear body that is pulled while hitting the tip of the cone-shaped portion has a high resistance to traction due to the presence of rigidity and the like, and the feed speed is reduced. If the feed speed decreases, the rotational speed of the rotating body becomes equal to the number of windings to be unwound, and the dismantling operation is smoothly performed. If the tension of the reel winder is set to a high value, when the part with a small number of turns is disassembled, the feed speed increases due to the tension of the reel winder, etc. It will return to the position of the tip of the part. In other words, the guide member of the present invention functions as an automatic feed speed adjusting device, and an appropriate dismantling operation can be realized even if the rotational speed of the rotating body is kept constant.

  According to a fourth aspect of the present invention, the guide member includes a circular plate having a plurality of holes through which the linear body passes in the peripheral portion, a center hole through which the core wire passes, and a conical portion. When the conical parts having the above are combined, the manufacturing process of the guide member is simplified.

By the way, the concentric strands of OPGW and the like that are disassembled using this dismantling / separating apparatus have many years of useful life, so that there is a breakage of the outer peripheral portion of the linear body due to deterioration, that is, “strand break” occurs. There may be. The linear body cannot enter the guide member or the guide tube at the cutting point, and the linear body may be entangled with the rotating body, which may seriously damage the dismantling and separating apparatus.
According to a fifth aspect of the present invention, a “wire breakage” detecting means is incorporated in the guide member having the structure of the fourth aspect of the invention. That is, a disc having a plurality of holes through which the linear body passes is coupled to the first rotating body via an insulating material, and the plurality of holes are covered with the insulator, and the disc is covered with the first rotating body and the wire. It is electrically insulated from the body. In such a state, a low voltage is applied between the concentric wires and the disk to detect the presence or absence of current flowing between them. Since the cut linear body collides with the surface of the guide member disk without entering a plurality of holes, the current flowing at this time can be detected to detect “wire breakage”. It is possible to take measures such as emergency stop. The voltage applied between the concentric wires and the peripheral portion of the guide member is a low voltage, and there is no danger to workers.

  In addition, in old OPGW and the like whose service life has passed, many metal oxides are generated on the surface or dust is attached, and these are peeled off and scattered when unraveled at the tip of the guide member. For this reason, normal dismantling work is hindered, and when the adhering matter is caught in a rotating part such as a bearing, the durability of the apparatus is deteriorated. When the vacuum suction device is installed in the vicinity of the guide member as in the sixth aspect of the invention, it is possible to suck and remove the separated deposits and prevent the dismantling and sorting device from being damaged.

  As in the seventh aspect of the invention, the sorting apparatus of the present invention is particularly suitable for collecting OPGW and recycling it. The disassembly / separation apparatus of the present invention does not hinder normal disassembly even if the work speed of the separation is increased, and can efficiently take out the aluminum tube that is the core wire of the OPGW as it is.

Hereinafter, the concentric stranded wire disassembly and separation apparatus of the present invention will be described with reference to the drawings. In the embodiment described here, the dismantling / sorting device of the present invention is applied to the dismantling / sorting of OPGW.
FIG. 1 is a front view generally showing an embodiment of the disassembly and separation apparatus of the present invention, FIG. 2 is an enlarged view of the vicinity of a guide member constituting the main part of the present invention, and FIG. 3 is an assembly view of each part. is there. FIG. 4 shows a disc and a conical part of the guide member, and FIG. 5 shows an insulating part. In these drawings, components corresponding to parts of the dismantling and separating apparatus in FIG.

  The basic configuration and operation of the disassembly / separation apparatus in the embodiment of FIG. 1 are the same as those of the disassembly / separation apparatus 1 shown in FIG. That is, the first rotating body 10 and the second rotating body 20 supported by the rollers 70 and 80 are provided, and both the rotating bodies are driven by a drive motor 56 through a gear transmission mechanism around a steel wire (linear body) around the OPGW. ) Is rotated in the opposite direction to the winding direction to rewind the steel wire. A winding mechanism 30 is disposed between the first rotating body 10 and the second rotating body 20, and is placed on a frame 31 that is pivotally supported by both rotating bodies, and is an aluminum core that is the core of the OPGW. Wind up the tube. The OPGW to be disassembled is supplied to the first rotating body 10 from the left side of FIG. 1, that is, from the front side of the disassembling and separating apparatus 1, and the unwound and separated steel wire passes through the plurality of guide tubes 4 and passes through the second rotating body. It converges behind 20 and is sent out from the dismantling and sorting device. However, in this dismantling and separating apparatus of the present invention, a reel winder 90 having a constant torque clutch is installed at the rear of the apparatus. In the constant torque clutch, when a torque exceeding a certain value acts, “slip” occurs and power transmission is interrupted. The concentric stranded wire is pulled by the reel winder 90 with a constant tension and sent to the apparatus.

  The disassembly / separation apparatus of this embodiment is the same as the disassembly / separation apparatus 1 shown in FIG. 7 and the like in the basic configuration and the like, but is improved in several points. For example, in the front part of the apparatus, a feeding device 91 having a driving device for driving a guide roller is installed, and OPGW separated into an aluminum tube and a plurality of outer peripheral steel wires at the start of dismantling and separation work, The feeding device 91 is driven and fed to the rear of the device. In the middle of the apparatus, a protective cover 92 made of a wire mesh that covers the rotating body and the guide tube is installed, and a control device that stops the rotation of the rotating body when the protective cover 92 is opened is provided. Safety measures have been taken so that no danger is incurred. Moreover, in the dismantling and separating apparatus of this embodiment, a plurality of steel wires are inserted into the guide tube 4 at the same time and converged behind the second rotating body 20, so that the number of guide tubes 4 is It is about half of the number of steel wires wound around the outer periphery of the OPGW. This is because, when the steel wires sent one by one are converged as in the apparatus of FIG. 7, when the steel wires return to their original shape, a steel wire is produced that is pushed out to the center, and the steel wires In other words, it was a measure taken because it became clear that “sagging” could occur and hinder smooth dismantling work.

  The guide member of the present invention is attached to the bearing portion 13 of the hollow shaft 14 of the first rotating body 10 in order to unwind the OPGW steel wire in an appropriate state and send it to the guide tube 4.

The number of holes 19D of the disc 19A is formed in a position corresponding to the space 18 of the flange 13A by a number equal to the number of the guide tubes 4 (four in this embodiment). Further, a hole 19G into which the boss portion 19F of the insulating plate 19C is fitted is formed in the center of the disc 19A, and a bolt hole for fastening to the flange 13A through the insulating plate 19C with a bolt (not shown) in the outer peripheral portion. Is formed. The bolt for fastening the disc 19A to the flange 13A is also fastened to the disc 19A via an insulating material.

  As shown in FIG. 4, a center hole 19H through which the aluminum tube passes is provided at the center of the cone part 19B, and the rear part is inserted into the hollow shaft 14 through the through hole of the boss part 19F of the insulating plate 19C. A shaft portion is provided. Further, a bolt hole 19I for attaching a bolt and a recess are formed in the conical portion 19E, and the disc 19A and the cone part 19B are integrally coupled with an insulating plate 19C sandwiched between bolts (not shown). Fastened to the flange 13A of the hollow shaft 14. In this embodiment, the disc 19A and the conical part 19B are separate parts, and both are electrically insulated by the boss portion 19F of the insulating plate 19C when fastened by bolts, but the insulation is necessary. If there is not, the disc 19A and the conical part 19B may be integrated into one part.

The insulating plate 19C is made of a synthetic resin such as bakelite or an insulating material such as ceramics, and as shown in FIG. 5, a boss portion 19F is provided at the center, whereby a disc 19A forming a peripheral portion of the guide member is , Electrically insulated from the hollow shaft 14 of the rotating body 10 and insulated from the cone part 19B. As can be seen from the assembly diagram of FIG. 3, an insulating insert 19K having a bell mouth-shaped passage 19J is fitted into the plurality of holes 19D through which the steel wire of the disc 19A passes, and between the disc 19A and the steel wire. Is also insulated. The insulating insert 19K passes through the passage 19J while being slidably contacted, so that the insulating insert 19K is formed of a wear-resistant insulating material such as ceramics, and the rear portion is held in the hole 19D of the insulating plate 19C. The part protrudes forward of the disk 19A.
A low voltage that does not affect the human body is applied between the OPGW steel wire fed to the dismantling and separating device and the disc 19A, and the control device that controls the operation of the dismantling and separating device includes both A detection device for detecting a current flowing between them is incorporated. Although not shown in order to apply a voltage, a contact terminal that is always in contact with the steel wire is disposed at the inlet of the apparatus, and a contact terminal that is always in contact with the steel wire 19A is disposed near the disk 19A.

  Next, the operation and the like of the dismantling and separating apparatus provided with the guide member of the present invention will be described. As schematically shown in FIG. 1, a reel winder 90 having a constant tension function by a constant torque clutch is installed behind the dismantling and separating apparatus 1 and converged on the rear side of the second rotating body 20. Y is pulled by the reel winder 90 and wound around it. That is, the OPGW to be disassembled is sent to the disassembly / separation apparatus 1 by the tension of the reel winder and disassembled. The guide member of the present invention is installed at a position where the steel wire Y wound around the outer periphery of the OPGW is unwound and introduced into the guide tube, and the steel wire Y extends along the conical portion 19F of the guide member. While expanding, it passes through the peripheral holes 19D and is smoothly guided to the guide tube 4.

  The reel winder 90 installed behind the dismantling and separating apparatus 1 has a constant tension function, and pulls the steel wire Y with a constant tension. The tension is set to be high, and the drawn steel wire Y of OPGW is unraveled while being in contact with the tip portion of the conical portion 19F as shown in FIG. The rotating bodies 10 and 20 are driven at a substantially constant rotational speed, and when the number of windings of the steel wire Y is uneven, when the portion with a large number of windings is fed, the rewinding of the steel wire Y is not in time. , Resistance to traction increases. As a result, the feed speed of the steel wire Y decreases, and if the feed speed decreases, the rotational speed of the rotating bodies 10 and 20 coincides with the number of windings to be unwound, and an appropriate dismantling work is performed. Conversely, when a portion with a small number of windings is fed, the feed speed of the steel wire Y is increased by the tension of the reel winder 90, and the “unwinding position” is drawn toward the tip of the conical portion 19F. As described above, the guide member according to the present invention functions to adjust the feeding speed of the line from the concentricity so as to match the rotational speed of the rotating bodies 10 and 20, and can be stably disassembled even if the rotational speed of the rotating body is constant. Can be implemented.

  Instead of pulling the steel wire Y with a constant tension by the reel winder 90, the OPGW can be fed into the dismantling and separating device by the feeding device 91 placed at the front of the device. That is, a constant torque clutch is attached to the driving device for the guide roller, and OPGW is sent to the guide member 19 of the device with a constant “thrust”. Even if such a feeding means is used, it is obvious that an appropriate dismantling operation can be performed in the same manner as in the case of towing with the reel winder 90.

  When the OPGW in which the “wire breakage” has occurred is sent to the dismantling / separating device, the cut steel wire is sent without being pulled from the preceding portion, and therefore, in the insulating insert 19K attached to the hole 19D of the disc 19A. It cannot enter and contacts the surface of the disk 19A. A low voltage is applied between the circular plate 19A forming the periphery of the guide member and the steel wire, but normally no current flows because they are electrically insulated. However, when the cut steel wire comes into contact with the disk 19A, a current flows. The control device of the dismantling and separation device incorporates a detection device that detects the current flowing at this time, and thus it is possible to detect "wire breakage" and to stop the rotation of the rotating body urgently It is possible to take measures such as preventing damage to the dismantling and sorting apparatus due to the cut steel wire.

  FIG. 6 shows a dismantling and separating apparatus in which a vacuum suction device (vacuum cleaner) 52 is installed in the vicinity of the guide member 19. In many cases, the old OPGW that has reached the end of its useful life has a metal oxide deposited on its surface or dust or the like attached thereto. The deposit of OPGW peels off near the tip of the cone part 19B of the guide member 19 where the steel wire is unraveled and falls downward. In this embodiment, a fallen deposit 54 is placed in a rectangular shape below the conical part 19B of the guide member 19 and collected deposits are collected therein. A slit is opened in the upper plate of the gantry 51 and a vacuum suction device 52 is connected, and the fallen deposits are removed by suction with a vacuum. In this embodiment, the enclosure plate 54 is provided below, but an enclosure that covers the periphery of the guide member 19 may be provided and connected to a vacuum suction device to suck scattered deposits.

  As described above in detail, in the present invention, in order to disassemble the wire from the concentricity, the core wire is taken out while rewinding the linear body by the rotating body rotating in the direction opposite to the winding direction of the linear body wound around the outer periphery. In the dismantling and separating apparatus, a guide member provided with a plurality of holes through which the linear body passes in the peripheral portion and a conical portion that tapers forward is attached to the front portion of the rotating body, It enables efficient dismantling work. Therefore, it goes without saying that the sorting apparatus of the present invention is not limited to OPGW, but can be applied as a device for breaking up and sorting lines in general concentric form. Further, various modifications different from the above-described embodiment, for example, changing the structure of the second rotating body that does not pass through the core wire to the first rotating body, configuring the guide member by combining three or more parts, It is clear that this is possible.
