  For example, when the rotating plate portion 122 rotates in a predetermined direction (counterclockwise in FIG. 13), the second gear portion 134 moves in the same direction (counterclockwise) due to the engagement between the fixed gear portion 136 and the second gear portion 134. Around). Then, the rotation of the second gear portion 134 is transmitted to the first gear portion 133 through the individual shaft 132, and the first gear portion 133 also rotates in the same direction (counterclockwise). Then, the relay gear portion 114 that meshes with the first gear portion 133 rotates in the reverse direction (clockwise). Thereby, the wire end holding part 110 connected through the relay gear part 114 and the support shaft part 113 rotates in the same direction as the relay gear part 114. That is, the wire end holding part 110 tries to rotate in the direction opposite to the rotation direction of the rotating plate part 122. Here, the gear diameter, the number, and the like are set so that the rotation speed of the wire end holding section 110 is the same as the rotation speed of the rotating plate section 122.

  Therefore, while the rotating plate part 122 tries to rotate in a predetermined direction, the wire end holding part 110 tends to rotate relative to the rotating plate part 122 in the opposite direction. As a result, while the rotating plate portion 122 rotates in a predetermined direction, the wire end holding portion 110 is maintained in a state where the rotation is stopped when viewed as the entire apparatus. Thereby, the other end part of the some electric wire 12 rotates in the predetermined direction as a whole, and when the some electric wire 12 is seen separately, it will be maintained in the state which does not rotate. Thereby, as shown in FIG. 14, while rotating the whole of each electric wire 12 in the same direction as the direction which twists together, rotation of the one end part of each electric wire 12 can be suppressed and those twists can be suppressed.

  In addition, each part of this apparatus performs the following operation | movement, being controlled by the control unit 90 by operating start switch SW92, and manufactures a twisted electric wire.

  15-17 is explanatory drawing which shows the operation | movement of the manufacturing apparatus 20 of this twisted electric wire, and the manufacturing method of a twisted electric wire.

  First, both ends of the plurality of electric wires 12 are held by the end rotation mechanism units 100A and 100B, and the plurality of electric wires 12 are held in a straight line state.

  In this state, the central portion in the extending direction of the plurality of electric wires 12 is held in a fixed arrangement form by the two electric wire intermediate holding portions 40A and 40B. In this state, it is preferable that the wire intermediate holding portions 40A and 40B are adjacent to each other with as little gap as possible.

  When the operator operates the start switch SW92, the control unit 90 drives the rotation driving units 60 and 126 to rotate, and drives the twist moving mechanism unit 80. Thereby, the two electric wire intermediate holding portions 40A and 40B rotate in opposite directions around the central axis of the entire plurality of electric wires 12, and the electric wire intermediate holding portion 40A moves from the central portion of the electric wires 12 toward one end side, The electric wire intermediate holding portion 40B moves from the central portion of the electric wire 12 toward the other end side. The rotational speed and moving speed of the electric wire intermediate holding portions 40A and 40B at this time are appropriately adjusted and set according to the twist pitch of the twisted electric wire to be manufactured. Although it is preferable that the rotation speed and the moving speed of the electric wire intermediate holding portions 40A and 40B are the same, this is not essential.

  Also, the wire end holding portion 110 of the one end rotation mechanism portion 100A rotates around the central axis of the entire plurality of wires 12 at the same rotational speed and the same rotation direction as the one wire intermediate holding portion 40A. Similarly, the wire end holding portion 110 of the other end rotation mechanism portion 100B rotates around the central axis of the entire plurality of wires 12 at the same rotation speed and the same rotation direction as the other wire intermediate holding portion 40B.

  Then, as shown in FIG. 16, the some electric wire 12 is twisted one by one between the electric wire middle holding | maintenance parts 40A and 40B.

  Further, between the one wire intermediate holding portion 40A and the one end rotation mechanism portion 100A, the plurality of wires 12 rotate (revolve) in the same direction, so that twisting is suppressed and the plurality of wires 12 are arranged in parallel. Keep state. Moreover, each electric wire 12 tries to rotate in the twisting direction by the rotation of the electric wire intermediate holding portion 40A, but the other end portion of each electric wire 12 is rotated in its entire rotation direction by the end rotation mechanism portion 100A. And the other end of each electric wire 12 is kept in a non-rotating state, so that the twist is suppressed.

  Similarly, since the plurality of wires 12 rotate (revolve) in the same direction between the other wire intermediate holding portion 40B and the one end rotation mechanism portion 100B, twisting is suppressed, and the plurality of wires 12 are Keep parallel. Moreover, each electric wire 12 tries to rotate in the twisting direction by the rotation of the electric wire intermediate holding portion 40B, but the other end portion of each electric wire 12 is rotated in its entire rotation direction by the end rotation mechanism portion 100B. And the other end of each electric wire 12 is kept in a non-rotating state, so that the twist is suppressed. As a result, the plurality of electric wires 12 are twisted together by the rotation of the two electric wire intermediate holding portions 40A and 40B while the individual twists are suppressed at both end portions.

  And as shown in FIG. 17, when the electric wire middle holding | maintenance part 40A, 40B reaches the both ends of the several electric wire 12, what the several electric wire 12 was twisted entirely is manufactured.

  According to the twisted wire manufacturing apparatus 20 and the twisted wire manufacturing method configured as described above, the wire intermediate holding portion 40A is rotated and driven from the intermediate portion in the extending direction of the plurality of wires 12 toward one end portion. While moving, while moving the electric wire intermediate holding portion 40B in the direction opposite to the electric wire intermediate holding portion 40A, the electric wire intermediate holding portion 40B is moved from the intermediate portion in the extending direction of the plurality of electric wires 12 to the other end portion. Therefore, the plurality of electric wires 12 can be twisted together as quickly as possible. In particular, as compared with the case where a plurality of electric wires are sequentially twisted from one end portion toward the other end portion, it is possible to rapidly twist the wires at a speed twice or more.

  In particular, since the wire intermediate holding portions 40A and 40B are twisted while moving from the intermediate portion in the extending direction of the wire 12 to the end side, the wire intermediate holding portions 40A and 40B are twisted at each position where they are moved. Since the positions are concentrated, the twisted form is stable.

  Moreover, since the said twist is performed in the state which hold | maintained the some electric wire 12 in linear form with a pair of edge part rotation mechanism part 100A, 100B, the stable twist can be implemented.

  In addition, the pair of end rotation mechanisms 100A and 100B support the entire ends of the plurality of electric wires 12 in a rotatable manner, and also support each of the ends of the plurality of the electric wires 12 in a rotatable manner. Twist of the plurality of electric wires 12 can be suppressed outside the portions 40A and 40B, and the occurrence of twisting of the electric wires 12 can be suppressed. As a result, the gaps between the plurality of wires 12 are stabilized, and the signal transmission characteristics and the like of the twisted wires are stabilized.

  In particular, the pair of end rotation mechanism units 100A and 100B rotate and drive the entire ends of the plurality of electric wires 12 in synchronization with the rotation of the twist rotation driving units 50A and 50B, and the end portions of the plurality of electric wires 12 Are rotated in the direction opposite to the rotation direction of the entire end portions of the plurality of electric wires 12, so that the twisting of the plurality of electric wires 12 can be more reliably suppressed outside the intermediate wire holding portions 40A and 40B. In addition, the occurrence of twisting of each electric wire 12 can be more reliably suppressed.

  In addition, it is not essential that the edge part of the some electric wire 12 is hold | maintained by a pair of edge part rotation mechanism part 100A, 100B. For example, when twisting relatively short electric wires 12, it is not essential to hold the ends of the electric wires 12. Moreover, the structure by which the edge part of the some electric wire 12 is hold | maintained in a predetermined position in the state which can be revolved and rotated by inserting in an annular member may be sufficient. Further, in the end rotation mechanism units 100A and 100B, each gear may be omitted, and the plurality of electric wires 12 and each electric wire 12 may be held in a freely rotatable state, or the electric wire end holding unit may be rotated. The gears for making them may be omitted, and each electric wire 12 may be freely rotatable.

  In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
