Description

  The present invention relates to an apparatus and method for disassembling and separating a wire from a concentric wire such as an electric wire, in which another wire is wound around a core wire.

  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. 9, 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. 4 to 7. The operation when sorting the OPGW and the OPGW will be described in detail.

  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, as shown in the overall view of FIG. 4, 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. 4, that is, from the front side of the disassembling and separating apparatus 1, and the separated steel wire is converged at the rear of the second rotating body 20 and disassembled. Sent from the sorting device.

  As shown in FIG. 5, 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. In order to guide the striate body to be returned, a guide plate 19 provided with holes corresponding to the number of striatum bodies is mounted. 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 supported by the frame body 60 shown in FIG. 6 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 that meshes with the outer peripheral gear 12 (in FIG. 4, a part of the frame 60 and the driving roller). 70 only).

  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. 5) 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. 4, 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. 4, the plurality of steel wires are spread outward just after the hollow tube 61, and each steel wire is passed through the hole of the guide plate 19, and then the first rotating body 10. It 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 up by a steel wire winding drum (see FIG. 7). 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. 7, 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 behind, 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.
JP 2002-1003003 A Japanese Utility Model Publication No. 58-36510

  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 core wire after being disassembled is wound around a take-up drum placed in the dismantling and separating apparatus, and the linear body is converged at the rear of the apparatus and returned to the original form while being reeled back. Winded by a winder. Thus, with this dismantling and separating apparatus, the concentric wires can be disassembled efficiently and smoothly, and the core wire and the linear body can be separated and collected in the form of being wound around the drum, but the processing speed of the dismantling and separating work is increased. It has been found that the following phenomenon occurs when the linear body converges when the line passes through the concentric lines at high speed.

  After the linear bodies are unraveled in front of the first rotating body, each passes through the guide tube to the second rotating body, and gathers again at the rear part. Each of the linear bodies is processed to be wound around the core wire and is easily “twisted”. Therefore, as shown in FIG. A space is formed. At this time, all the linear bodies are arranged on the outer periphery, and the shape as shown in the left figure is not always maintained, and one linear object enters the central space as shown in the right figure. Sometimes.

  In this state, the linear body that has entered the center has a shorter trajectory until it is wound around the reel winder than the linear body that is wound around the outer periphery. An “extra length” occurs, and it becomes slack. The slacked linear body is bent and pushed outward, and after a certain period of time, it is caught again in the outer linear body, and another linear body enters the central space. In such a situation, the “extra length” is absorbed in the winding process of the reel winder, and there is no particular problem in the work. However, when the line feed speed is higher than the concentricity (about 10 m / min when disassembling a general OPGW), there is no time to move the linear body entering the center to the outer circumference. The “long” part is fed forward. The “extra length” that moves forward may travel in the guide tube and extend from the guide tube entrance to the vicinity of the guide plate of the first rotating body.

There is nothing that regulates the trajectory of the linear body in front of the guide tube entrance, and if the linear body is slackened, it may bulge outward due to centrifugal force and the trajectory may become irregular and get entangled with the device. When this phenomenon occurs, dismantling work cannot be continued.
It is an object of the present invention to solve such problems by simple means and to improve the processing performance of the apparatus by enabling smooth disassembly and separation work even at high speed.

In view of the above-mentioned problems, the present inventors rewind a linear body wound around the outer periphery using two rotating bodies and a guide tube, and disassemble a plurality of wires into the guide tube in a concentric arrangement. The present invention has been completed by finding that the above-mentioned phenomenon can be avoided by passing the linear bodies as a set, converging behind the rotating body and winding up. 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;
The number of the guide tubes is set to a number smaller than the number of concentric linear bodies to be disassembled and separated,
While rotating the first rotating body and the second rotating body in synchronization with a direction opposite to the winding direction of the linear body, by feeding a wire from the concentric front from the front of the first rotating body, The core wire is taken up by the take-up mechanism, a plurality of the linear bodies are passed through the guide tube, and converged to the rear of the second rotating body to be taken up.
This is a dismantling and separating apparatus characterized by this.

  According to a second aspect of the present invention, an inlet guide member having a bell mouth shaped passage can be installed at the inlet of the guide tube.

  According to a third aspect of the present invention, a reel winder having a constant tension function is arranged behind the second rotating body, and the linear body converged behind the second rotating body is formed by a reel winder. It is preferable to be pulled up and wound up.

  The disassembly and separation apparatus according to the present invention is particularly suitable for disassembling and separating a concentric stranded wire having an aluminum tube containing an optical fiber as a core, that is, OPGW, as described in claim 4.

The present invention can also be implemented as a method invention. That is, even when the number of guide tubes is the same as the number of concentric strands to be disassembled and separated, for example, two linear bodies are set as one set. The guide tube may be passed through. As a method invention, as described in claim 5,
"A method of disassembling and separating lines 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 that is pivotally supported by the first rotating body and the second rotating body in a stationary state uses a disassembling and separating device that is disposed between the first rotating body and the second rotating body,
While rotating the first rotating body and the second rotating body in synchronization with a direction opposite to the winding direction of the linear body, by feeding a wire from the concentric front from the front of the first rotating body, The core wire is wound around the winding mechanism, a plurality of the linear bodies are passed through the guide tube as a set, and converged to the rear of the second rotating body and wound.
This is a disassembly and separation method characterized by this.

  In the dismantling and separation apparatus that is the basis of the present invention developed by the present applicant, the linear body wound around the outer periphery is rewound using two rotating bodies and a guide tube, and converged behind the rotating body. Wind up. In the present invention, since a plurality of linear bodies are passed through the guide tube as a set, the number of guide tubes and the number of holes provided in the guide plate for guiding the linear bodies to the guide tube are implemented as an apparatus. Is less than the number of linear bodies and is approximately half, and a plurality of linear bodies passing through each guide tube are converged rearward and wound on a reel winder.

When the linear bodies are assembled, the original concentric shape returns to a shape wound around the outer periphery of the line, and a space is formed inside. In this space, linear bodies may still enter, but in the present invention, a plurality of linear bodies return to their original shape while contacting each other. Even within the guide tube, one unit of linear bodies is sent while being in contact with each other, and even if an “extra length” occurs in one linear body that enters the center, it is constrained by other linear bodies. As a result, the “extra length” is prevented from proceeding forward. Therefore, the linear body is not loosened in front of the first rotating body, and normal dismantling work can be continued. The “extra length” of the central linear body is absorbed in the winding process of the reel winder after a certain time.
Further, since a plurality of linear bodies are passed through the guide tube, the guide tube has a large diameter. As the diameter increases, the weight of the guide tube increases, but the rigidity against bending also increases, and the bending of the guide tube due to the centrifugal force accompanying rotation can be reduced by selecting the material of the guide tube.

  When an inlet guide member having a bell mouth shaped passage is installed at the inlet of the guide tube as in the invention of claim 2, the linear body is introduced more smoothly into the guide tube.

  As in the invention described in claim 3, a reel winder having a constant tension function is disposed behind the second rotating body, and the converging linear body is pulled by the reel winder to supply concentric wires to the apparatus. In addition, an overhead winch placed in front of the apparatus can be omitted. Also, since the reel winder has a constant tension function and pulls at a constant tension, the feeding speed automatically changes according to the resistance of the linear body due to uneven winding number, etc., and smoother disassembly work Can be implemented.

  As in the fourth aspect of the present invention, the disassembly / separation 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.

  The invention of claim 5 is an invention of a method, and can be carried out even if the number of guide tubes of the dismantling and separating apparatus is the same as that of the linear body. In the case of the same number, a plurality of linear bodies may be taken as a set, and the linear bodies may be passed through only the guide tubes equal to the number of sets.

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 a view showing a first rotating body of the present invention, and FIG. 3 is a view showing a guide tube. In these drawings, components corresponding to parts of the dismantling and separating apparatus in FIG. 4 and the like are denoted by the same reference numerals.

  The basic configuration and operation of the disassembly / separation apparatus of 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 rollers 70 and 80 are provided, and both the rotating bodies are driven by a drive motor 56 through a gear transmission mechanism to a steel wire (linear body) around the OPGW. ) Is rotated in the opposite direction to the winding direction to rewind the outer 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 wound on the drum of the reel winder 90.

The disassembly / separation apparatus of this embodiment is the same as the disassembly / separation apparatus 1 shown in FIG. 4 and the like in the basic configuration and the like, but is improved in several points. For example, a guide roller 91 with a feeding device provided with a driving device is installed in the front part of the device, and OPGW separated into an aluminum tube and a plurality of outer peripheral steel wires at the start of the dismantling separation work is fed in. Drive the device and feed it behind 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.
Further, in the disassembly and separation apparatus of this embodiment, the guide member 19 attached to the bearing portion 13 of the hollow shaft 14 of the first rotating body 10 includes a disk 19A having a hole through which a steel wire passes in the peripheral portion. , And a conical part 19B tapering forward. The guide member 19 has a function of properly unwinding the OPGW steel wire and feeding it to the guide tube 4 and also automatically adjusting the feeding speed according to the non-uniform number of windings.

  In this dismantling and sorting apparatus that is an embodiment of the present invention, a plurality of steel wires are simultaneously inserted into the guide tube 4 and converged behind the second rotating body 20. Therefore, the number of guide tubes 4 is less than the number of steel wires wound around the outer periphery, and is set to half that number when the number of steel wires is even. The dismantling / separating apparatus in this example is designed to be used mainly for dismantling / separating an OPGW wound with 8 steel wires, and the number of guide tubes 4 is four. Are inserted into the guide tube 4 as a set of two. The number of holes provided in the peripheral portion of the guide member 19 is four as well as the number of the guide tubes 4.

  As shown in FIG. 2, the disk body 11 of the first rotating body 10 in this embodiment is provided with four mounting holes 11 </ b> A having a substantially rectangular shape in the disk portion for mounting the four guide tubes 4. ing. Further, as shown in FIG. 3, an inlet guide member 41 having a bell mouth-shaped passage is fitted and attached to the inlet side end of the guide tube 4 so that the two linear bodies Y can pass smoothly. Furthermore, a guide tube mounting plate 42 is attached to the inlet guide member 41. The guide tube mounting plate 42 is formed with a projection 42A having a shape corresponding to the mounting hole 11A. The guide tube mounting plate 42 is fitted with the projection 42A into the mounting hole 11A, and a disk is formed by a bolt (not shown). It is fixed to the disk part of the body 11. In addition, the attachment structure of the guide tube 4 to the 2nd rotary body 20 is the same as the structure of a 1st rotary body.

Here, an operation method of the dismantling and sorting apparatus of this embodiment will be described. First, the OPGW to be disassembled is unwound for a predetermined length, and the aluminum pipe as the core wire and the plurality of steel wires on the outer periphery are separated. The separated aluminum tube of OPGW passes through the hollow shaft 14 of the first rotating body 10 and is wound around the core winding drum 33 of the winding mechanism 30 as in the apparatus of FIG.
A plurality of steel wires on the outer periphery are collected two by two, passed through four holes formed in the peripheral portion of the guide member part 19A, and inserted into each guide tube 4 in units of two. The two steel wires pass through the guide tube 4 in a state where they are in contact with each other, are sent to the second rotating body 20, converge at the rear thereof, and are wound up by the reel winder 90.

  When the steel wires are assembled, it automatically returns to the original form wound around the outer periphery of the OPGW. At this time, if the steel wire enters into the center and an “extra length” is generated in the steel wire, the “extra length” will be pushed forward. Since it is in a state where it is in contact with one steel wire of the steel wire, it is sent while being constrained to each other, the advance of the “extra length” is impeded, and the extra length moves to the front of the first rotating body 10 There will be no slack. The “extra length” behind the second rotating body 20 is absorbed by the winding action and disappears after a certain period of time.

  Some OPGWs have an odd number of steel wires wound around the outer periphery of an aluminum tube. When disassembling such an OPGW, an unbalance occurs in the number inserted into the guide tube 4, and the weight distribution of the rotating bodies becomes non-uniform. At this time, the static balance or dynamic balance of the rotating body can be achieved by attaching so-called dummy steel wires that do not move in the small number of guide tubes.

  As described above in detail, the present invention is a device that unwinds a linear body wound around the outer periphery using two rotating bodies and a guide tube, and disassembles the wire from the concentricity. The linear bodies are passed as a set, converged behind the rotating body and wound up. Therefore, it is needless to say that the disassembly / separation apparatus of the present invention can be implemented using the same number of apparatuses as the linear body, and can be applied not only to OPGW but also as an apparatus for disassembling and separating lines from general concentric lines. . Also, various modifications different from the above-mentioned embodiment, for example, changing the structure of the second rotating body through which the core wire does not pass to the first rotating body, instead of pulling the concentric wire to the device by the tension of the reel winder Obviously, it is possible to install the overhead wire winch forward and push the wire concentrically into the device.
