  FIG. 1 shows a bind winding device 1. The bind winding device 1 includes a power transmission conversion unit 2 and an arm turning drive unit 4. The power transmission conversion unit 2 includes a connecting cylinder part 21, a transmission shaft 22, a storage frame 23, a first gear 24, a second gear 25, a third gear 26, and a fourth gear 27. The fifth gear 28, the sixth gear 29, the seventh gear 30, the eighth gear 31, and the traveling roller 32 are provided. Each gear 24-31 is comprised, for example from metal bevel gears. The first gear 24 is connected to the connecting cylinder portion 21 via the transmission shaft 22. The first gear 24 rotates around the axis P1 by rotating the common operation rod 100 around the axis P1. A tooth portion (not shown) that meshes with the second gear 25 is formed on the upper surface of the first gear 24. The rotation center (axial center P2) of the second gear 25 is orthogonal to the rotational center (axial center P1) of the first gear 24.

  In addition to the second gear 25, a fourth gear 27 and a fifth gear 28 are meshed with the first gear 24. The fourth gear 27 and the fifth gear 28 are formed with a small diameter with respect to the second gear 25. The fourth gear 27 and the fifth gear 28 are meshed with the third gear 26. That is, the first gear 24 is meshed with the third gear 26 via the fourth gear 27 and the fifth gear 28. As shown in FIG. 2, the third gear 26, the fourth gear 27, and the fifth gear 28 are arranged on the left and right of the second gear 25 with the axis P1 as the center. The second gear 25 meshes with teeth (not shown) formed on the inner surface side of the third gear 26 arranged on the left and right.

  As shown in FIG. 2, the second gear 25 is formed with a second wire guide groove 25 a for housing a part of the wire 110 in the axial direction. The second wire guide groove 25a is formed so as to extend from the outer peripheral surface of the second gear 25 toward the rotation center (axial center P2) of the second gear 25. The second gear 25 is formed with the second wire guide groove 25a, so that a part of the wire 110 in the axial direction from the rotation center (axial center P2) portion of the second gear 25 from the radial direction can be obtained. It can be taken in and out.

Also requires a wire guide groove. Therefore, in the first embodiment, as shown in FIG. 3, the storage frame 23 is also formed with a first wire guide groove 23a for storing a part of the wire 110 in the axial direction. An electric wire guide groove (not shown) is also formed in the arm turning drive unit 4 that performs the above operation. As shown in FIG. 3, the first wire guide groove 23 a formed in the storage frame 23 has a width on the opening side larger than the width of the terminal portion.

  On one side of the power transmission conversion unit 2, an arm turning drive unit 4 is provided. The arm turning drive unit 4 includes a turning shaft main body 41, a cover 42, and an arm mounting shaft 43. A base end portion 41 a of the pivot shaft main body 41 is connected to the second gear 25. The rotation center of the turning shaft main body 41 coincides with the rotation center (axial center P2) of the second gear 25. An arm mounting shaft 43 is connected to the free end side of the pivot shaft main body 41. The rotation center of the arm mounting shaft 43 matches the rotation center of the second gear 25. The arm turning drive unit 4 has the same shape as the wire guide groove 23a in any of the turning shaft main body 41, the cover 42, and the arm mounting shaft 43 in order to allow the electric wire 110 to enter the center of rotation of the second gear 25. An electric wire guide groove (not shown) is formed.

  A winding engagement arm 44 is detachably attached to the arm mounting shaft 43. The winding engagement arm 44 rotates in the same direction as the direction around the axis of the electric wire 110 by the rotation of the second gear 25 and can engage with the bind 111 located on the electric wire 110 side. The bind 111 is, for example, an electric wire obtained by insulatingly covering a linear metal member with a synthetic resin, and is used for bundling or fixing an overhead distribution electric wire or the like. As shown in FIG. 1, in the first embodiment, the binding 111 for winding around the electric wire 110 is formed in a spiral shape in advance, and the spiral diameter thereof is on the winding engagement arm 44 at the time of turning. It is set to a diameter that can be engaged.

  The winding engagement arm 44 is composed of a rod-like member bent in a substantially U shape, and the distal end side extends in a direction away from the axis P2. A fitting portion (not shown) is formed at the base end portion of the winding engagement arm 44. By fitting the base end portion to the arm mounting shaft 43, the winding engagement arm 44 is The arm mounting shaft 43 can be mounted.

An eighth gear 31 is connected to both side surfaces of the traveling roller 32. The eighth gear 31 is engaged with a seventh gear 30 that is rotatably supported by the storage frame 23. The seventh gear 30 is engaged with the third gear 26 via a sixth gear 29 that is rotatably supported by the storage frame 23. That is, the rotation around the axis P1 of the common operation rod 100 is transmitted to the traveling roller 32 through a plurality of gears, and the traveling roller 32 can roll on the outer surface of the electric wire 110 in the axial direction.

  Next, the operation procedure and operation of the bind winding apparatus 1 in the first embodiment will be described.

  When starting the operation of winding the bind 111 around the electric wire 110, the bind winding device 1 is attached to the tip of the common operation rod 100 used in the indirect hot wire method. When the bind winding device 1 is mounted, the connecting cylinder portion 21 of the bind winding device 1 is fitted to the connecting shaft 101 of the common operation rod 100 while the lock screw 103 of the common operation rod 100 is moved downward. Then, the common operation rod 100 is rotated around the axis P <b> 1, and the connection pin 102 of the common operation rod 100 is engaged with the terminal portion of the lock groove 21 a of the connection cylinder portion 21 of the bind winding device 1. In this state, the lock screw 103 is rotated around the axis P <b> 1 and the lock screw 103 is moved upward, whereby the connecting cylinder portion 21 engaged with the connecting pin 102 is pressed by the lock screw 103. Thereby, the connection cylinder part 21 is prevented from moving in the vertical direction and around the axis P <b> 1 with respect to the connection shaft 101, and the mounting of the bind winding device 1 to the common operation rod 100 is completed.

  When the mounting of the bind winding device 1 is completed, the bind winding device 1 is moved upward by the operation of the common operation rod 100 by the operator, and the alignment of the bind winding device 1 with respect to the electric wire 110 is performed. As shown in FIG. 3, since the opening of the first guide groove 23a formed in the storage frame 23 of the bind winding device 1 is wide, the first guide groove 23a is formed at the position of the electric wire 110. By aligning the opening and further raising the common operation rod 100 in this state, the electric wire 110 can be guided to the second electric wire guide groove 25 a formed in the second gear 25. That is, since the wire guide groove similar to the first wire guide groove 23a and the second wire guide groove 25a is also formed in the arm turning drive unit 4, a part of the wire 110 in the axial direction is bound by winding. Without being interfered with each component constituting the attaching device 1, it is guided to the terminal portion of the second wire guide groove 25 a formed in the second gear 25.

  FIG. 4 shows a state in which the electric wire 110 is guided to the terminal portion of the second electric wire guide groove 25 a formed in the second gear 25. In this state, as shown in FIG. 2, the electric wire 110 is positioned at the rotation center (axial center P2) portion of the second gear 25, and the rotation center of the second gear 25 and the axial center of the electric wire 110 are Will match. When the electric wire 110 is positioned at the center of rotation of the second gear 25 and the operator rotates the common operation rod 100 around the axis P1 in the direction of arrow F1, as shown in FIG. Is transmitted to the power transmission conversion unit 2 of the bind winding device 1. In this state, since the electric wire 110 has already entered the first guide groove 23a of the storage frame 23, the storage frame 23 does not rotate in the direction of the arrow F1, and the first gear 24 is centered on the axis P1. Will rotate as.

  When the first gear 24 rotates, the second gear 25 meshing with the first gear 24 rotates about the axis P2, and the rotational force is generated by the rotation shaft main body 41 and the arm of the arm rotation drive unit 4. This is transmitted to the winding engagement arm 44 via the mounting shaft 43. As a result, the winding engagement arm 44 turns around the axis P2 as shown by the arrow F2, and engages with the bind 111 supplied to the vicinity of the electric wire 110 by another operator, for example. . The bind 111 engaged with the winding engaging arm 44 is guided around the axis of the electric wire 110, and the bind 111 is wound around the electric wire 110 from the circumferential direction.

  Further, as shown in FIG. 1, by rotating the common operation rod 100, the traveling roller 32 that is in contact with the electric wire 110 is also driven to rotate, and the bind winding device 1 is connected to the electric wire 110 as indicated by an arrow F <b> 3. It will move in the axial direction. Then, by continuing to rotate the common operation rod 100, the winding engagement arm 44 is continuously swiveled around the axis P2, and the traveling roller 32 is also continuously moved in the axial direction of the electric wire 110. As a result, the binding 111 is continuously wound around the electric wire 110.

  Here, the second gear 25 is formed with the second wire guide groove 25a as shown in FIG. 5, and therefore the second gear 25 has a portion where the second wire guide groove 25a is formed. Will not mesh with the first gear 24. However, in this case, the second gear 25 meshes with the third gear 26 that is rotationally driven by the first gear 24 via the fourth gear 27, so the second gear 25 is The meshes with these gears rotate continuously, and the winding of the bind 111 around the electric wire 110 is performed smoothly.

  In this way, the rotation direction around the axis P1 of the common operation rod 100 is converted by the power transmission conversion unit 2, and the winding engagement arm 44 interlocked with the second gear 25 of the power transmission conversion unit 2 is connected to the electric wire 110. The binding 111 can be wound around the electric wire 110 in a short time with a simple operation regardless of the difference in the skill of the operator who operates the common operation rod 100. it can. In addition, when the electric wire 110 enters the electric wire guide groove 25a, the electric wire 110 is positioned at the rotation center of the second gear 25, so that the electric wire 110 is prevented from interfering with the rotating second gear 25, Damage to the electric wire 110 can be prevented.

  Furthermore, since the power transmission conversion unit 2 has the traveling roller 32 that can roll the outer surface of the electric wire 110 in the axial direction by rotating around the axis P1 of the common operation rod 100. It is possible to automatically move the winding engagement arm 44 in the axial direction of the electric wire 110 while turning the engagement arm 44, and winding of the bind 111 becomes remarkably easy. Further, since the insulating operating rod to which the bind winding device 1 is mounted is composed of the common operating rod 100 on which various tools can be mounted, it is not necessary to newly manufacture a dedicated insulating operating rod, and the cost can be reduced. I can plan. And since the bind winding apparatus 1 can be operated by the common operation rod 100 which is used in the indirect hot wire method, the work can be smoothly advanced.

The transmission belt 33 is composed of a toothed belt, and the rotational force around the axis P <b> 1 of the common operation rod 100 is reliably transmitted to the eleventh gear 34. The driven roller 39 is disposed between the shaft center P <b> 1 and the shaft center P <b> 3, and is supported rotatably with respect to the storage frame 23. The driven roller 39 has a function of reducing the contact resistance between each component of the power transmission conversion unit 2 and the electric wire 110 entering the electric wire guide groove as much as possible, and facilitating movement of the electric wire 110 in the axial direction.

  A twelfth gear 35 is meshed with the eleventh gear 34. Similar to the first embodiment, the twelfth gear 35 is formed with a wire guide groove (not shown) for accommodating a part of the wire 110 in the axial direction. In addition to the twelfth gear 35, a fourteenth gear 37 and a fifteenth gear 38 are meshed with the eleventh gear 34. The fourteenth gear 37 and the fifteenth gear 38 are smaller in diameter than the twelfth gear 35. The fourteenth gear 37 and the fifteenth gear 38 are meshed with the thirteenth gear 36. That is, the eleventh gear 34 is meshed with the thirteenth gear 36 via the fourteenth gear 37 and the fifteenth gear 38. The winding engagement arm 44 can turn around the axis P <b> 2 by the rotation of the twelfth gear 35.

  In the second embodiment configured as described above, when the common operating rod 100 is rotated around the axis P1, the traveling roller 32 is driven to rotate, and the twelfth gear 35 is connected via the transmission belt 33. The winding engagement arm 44 is driven to rotate and pivots about the axis P2. In the second embodiment, since the driven roller 39 is provided, it is possible to reduce the resistance when the electric wire 110 contacts the terminal portion of the electric wire guide groove (not shown) formed in the twelfth gear 35. Thus, the driving force for moving the electric wire 110 in the axial direction is small.

(Embodiment 3)

The winding engagement arm 44 in the first embodiment extends in the direction away from the turning center (axial center P2), whereas the removal engagement arm 44 ′ in the fourth embodiment has a distal end side. It extends in a direction approaching the turning center (axial center P2). Thereby, the bind (not shown) wound around the electric wire 110 and the detaching engagement arm 44 ′ are easily engaged. When the bind 111 wound around the electric wire 110 is removed from the electric wire 110, as shown in FIG. 8, the detaching engagement arm 44 'is turned in the reverse direction (arrow F4 direction) with respect to the first to third embodiments. At the same time, it is necessary to move the disengaging engagement arm 44 'in the reverse direction (arrow F5 direction) with respect to the first to third embodiments.
