And a rear rotating clamp 90R. Since the configuration of the front rotation clamp 90F and the rear rotation clamp 90R is the same, only the configuration of the front rotation clamp 90F will be described here, and the description of the configuration of the rear rotation clamp 90R will be omitted.

  As shown in FIGS. 8A and 8B, the front rotary clamp 90F includes a clamp body 91, a shaft 92 that can slide back and forth (left and right in FIG. 8A) with respect to the clamp body 91, and a shaft.

When the shaft 92 moves rearward (rightward in FIG. 8A), the front rotary clamp 90F opens the grip arm 93 to release the first electric wire C1 and the second electric wire C2 (see FIG. 8A). When the shaft 92 moves forward (leftward in FIG. 8A), the grip arm 93 is closed to hold the first electric wire C1 and the second electric wire C2.

  An actuator 98 that slides the shaft 92 is connected to the shaft 92. The type of the actuator 98 is not particularly limited, and for example, a cylinder, a motor, or the like can be used. A motor 99 that rotates the front rotation clamp 90F around the rotation center axis 90c is connected to the front rotation clamp 90F. The front rotary clamp 90F rotates around the rotation center axis 90c while simultaneously holding the front ends of the first electric wire C1 and the second electric wire C2, and the rear rotary clamp 90R is the rear end of the first electric wire C1 and the second electric wire C2.

As will be described later, the front rotary clamp 90F is configured to be automatically movable back and forth. The rear rotary clamp 90R is configured to be movable back and forth manually. Next, a mechanism for moving the front rotary clamp 90F back and forth will be described.

  As shown in FIG. 1, a slider 101 is fixed to the front rotary clamp 90F. The slider 101 is engaged with a rail 102 extending in the front-rear direction, and is configured to be able to travel on the rail 102. A motor 103 that drives the slider 101 to travel on the rail 102 is connected to the slider 101. The motor 103 may be mounted on the slider 101 or may be connected to the slider 101 via a power transmission mechanism (not shown). The motor 103 is a motor capable of torque control and position control, and is configured by an AC servo motor in this embodiment. However, the type of the motor 103 is not particularly limited. When the slider 101 moves forward, the front rotation clamp 90F moves forward, and when the slider 101 moves backward, the front rotation clamp 90F moves backward.

  As shown in FIG. 9A, the slider 101 is provided with a connecting pin 104. The connection pin 104 is configured to be able to appear and retract in the slider 101, and is movable between a protruding position protruding from the slider 101 and a storage position stored inside the slider 101. FIG. 9A shows a state in which the connecting pin 104 is in the protruding position.

  The rail 81F with which the slider 82 of the front rotary clamp 90F is engaged is supported by the frame 89. The frame 89 is engaged with the rail 102 and is configured to be movable back and forth along the rail 102. A connecting member 105 is fixed to the frame 89, and a hole 105 a that engages with the connecting pin 104 is formed in the connecting member 105. As shown in FIG. 9B, when the connecting pin 104 of the slider 101 is engaged with the hole 105a of the connecting member 105, the slider 101 and the connecting member 105 are connected. Thereby, the front conveyance clamp 80F and the front rotation clamp 90F are connected, and the front conveyance clamp 80F can move back and forth together with the front rotation clamp 90F. The front transport clamp 80F moves back and forth by the driving force of the motor 103 that moves the front rotary clamp 90F back and forth. On the other hand, when the connecting pin 104 moves to the storage position, the engagement between the connecting pin 104 and the hole 105a is released. Thereby, the front conveyance clamp 80F and the front rotation clamp 90F are separated, and the front conveyance clamp 80F cannot move back and forth.

  As shown in FIG. 1, a tray 110 that collects twisted electric wires (that is, electric wires formed by twisting the first electric wires C1 and the second electric wires C2) is disposed below the front rotary clamp 90F and the rear rotary clamp 90R. ing. When the front rotary clamp 90F and the rear rotary clamp 90R release the twisted wires, the twisted wires are dropped by gravity and collected in the tray 110.

  As shown in FIG. 1, the wire processing apparatus 1 includes a control device 200. The control device 200 controls each actuator and each motor described above, and executes each process described above. The configuration of the control device 200 is not particularly limited, and may be, for example, a computer including a CPU, RAM, ROM, and the like.

  The above is the configuration of the wire processing apparatus 1. Next, operation | movement of the electric wire processing apparatus 1 is demonstrated. The following operation is executed under the control of the control device 200.

  As shown in FIG. 10, the electric wire processing apparatus 1 manufactures a twisted electric wire CT in which a first electric wire C1 and a second electric wire C2 having terminals T crimped at both ends are twisted together. In addition, the 1st electric wire C1 and the 2nd electric wire C2 have the core wire 151 and the coating | cover 152 which covers the circumference | surroundings of the core wire 151. FIG. The core 151 is made of a conductor such as metal, and the coating 152 is made of an insulating material such as vinyl resin. In the electric wire processing apparatus 1, the length of the twist electric wire CT to be manufactured can be adjusted. Since the front conveyance clamp 80F and the front rotation clamp 90F need to hold the front ends of the first electric wire C1 and the second electric wire C2, depending on the length of the first electric wire C1 and the second electric wire C2, the front conveyance clamp 80F. And the front-rear position of the front rotation clamp 90F is adjusted. When adjusting the front-rear position, the connecting pin 104 of the slider 101 engages with the hole 105a of the connecting member 105, and the front rotary clamp 90F and the front transport clamp 80F are connected. Then, the motor 103 is driven, and the front rotation clamp 90F and the front conveyance clamp 80F are moved to positions corresponding to the lengths of the first electric wire C1 and the second electric wire C2. That is, the front rotation clamp 90F and the front conveyance clamp 80F move to positions that hold the front ends of the first electric wire C1 and the second electric wire C2. When the front rotation clamp 90F and the front transport clamp 80F reach the above positions, the motor 103 stops and the engagement between the connecting pin 104 and the hole 105a is released. As a result, the front rotary clamp 90F is maintained movably back and forth by the motor 103, while the front transport clamp 80F cannot be moved back and forth.

  After adjusting the front and rear positions of the front rotary clamp 90F and the front transport clamp 80F, the following processes are executed. First, the operation of the wire end processing device 2 will be described.

  In the wire end processing device 2, when the front clamp support 30 is in the first front cutting position and the rear clamp support 37 is in the rear cutting position, the first electric wire C1 having the terminal T crimped to the front end portion thereof. Is fed forward by the feeding device 5. The first electric wire C1 is held by the first front clamp 14 and the rear clamp 36. And the cutting blade 33 cut | disconnects the 1st electric wire C1.

  Next, the front clamp support tool 30 moves to the first front stripping position, and the front stripping blade 34 strips off the coating on the front end portion of the first electric wire C1 held by the first front clamp 14. Further, the rear clamp support 37 moves to the rear stripping position, and the rear stripping blade 35 strips the coating on the rear end portion of the first electric wire C1 held by the rear clamp 36.

  Next, the front clamp support tool 30 moves to the first front terminal crimping position, and the front terminal crimping unit 40 crimps the terminal T to the front end portion of the first electric wire C1 held by the first front clamp 14. Further, the rear clamp support 37 moves to the rear terminal crimping position, and the rear terminal crimping unit 41 crimps the terminal T to the rear end portion of the first electric wire C1 held by the rear clamp 36.

  When the terminal T is crimped to the front end portion of the first electric wire C1, the front clamp support tool 30 moves from the first front terminal crimping position to the second front cutting position. When the terminal T is crimped to the rear end of the first electric wire C1, the first electric wire C1 is transferred from the rear clamp 36 to the discharge clamp 42, and the rear clamp support 37 is moved from the rear terminal crimping position to the rear cutting position. Move to.

  Next, the 2nd electric wire C2 by which the terminal T was crimped | bonded to the front-end part is supplied ahead by the feeder 5. FIG. Thereafter, similarly to the first electric wire C1, the second electric wire C2 is cut, the coating is stripped off, and the terminal T is crimped. That is, first, the second electric wire C <b> 2 is held by the second front clamp 24 and the rear clamp 36 and then cut by the cutting blade 33.

  Next, the front clamp support 30 moves to the second front stripping position, and the front stripping blade 34 strips off the coating on the front end portion of the second electric wire C2 held by the second front clamp 24. Further, the rear clamp support 37 moves to the rear stripping position, and the rear stripping blade 35 strips the coating on the rear end portion of the second electric wire C2 held by the rear clamp 36.

  Next, the front clamp support tool 30 moves to the second front terminal crimping position, and the front terminal crimping unit 40 crimps the terminal T to the front end portion of the second electric wire C2 held by the second front clamp 24. Further, the rear clamp support 37 moves to the rear terminal crimping position, and the rear terminal crimping unit 41 crimps the terminal T to the rear end portion of the second electric wire C2 held by the rear clamp 36.

  When the terminal T is crimped to the front end portion of the second electric wire C2, the front clamp support tool 30 moves from the second front terminal crimping position to the first front cutting position. When the terminal T is crimped to the rear end portion of the second electric wire C2, the second electric wire C2 is transferred from the rear clamp 36 to the discharge clamp 42, and the rear clamp support 37 is moved from the rear terminal crimping position to the rear cutting position. Move to.

  In the wire end processing device 2, the same operation is thereafter repeated. Thereby, the 1st electric wire C1 and the 2nd electric wire C2 by which the terminal T was crimped | bonded by the both ends are discharged | emitted from the electric wire end processing apparatus 2 alternately.

  The discharge clamp 42 that has received the first electric wire C1 from the rear clamp 36 moves while holding the first electric wire C1, and delivers the first electric wire C1 to the intermediate clamp 50. The intermediate clamp 50 receives the first electric wire C1 from the discharge clamp 42 at the receiving position.

  The discharge clamp 42 delivers the first electric wire C1 to the intermediate clamp 50, then returns from the delivery position to the receiving position, and receives the second electric wire C2 from the rear clamp 36. The discharge clamp 42 moves from the receiving position to the delivery position after receiving the second electric wire C2. Then, the discharge clamp 42 delivers the second electric wire C <b> 2 to the intermediate clamp 50.

  The intermediate clamp 50 that has received the first electric wire C1 and the second electric wire C2 moves to the delivery position and delivers the first electric wire C1 and the second electric wire C2 to the holding clamp 60. At this time, the clamp body 63 of the holding clamp 60 is raised, the rear end portion of the first electric wire C1 is inserted into the first holding portion of the holding clamp 60, and the rear end portion of the second electric wire C2 is the second end of the holding clamp 60. Inserted into the holding part. Then, the intermediate clamp 50 opens the grip arm 55 and returns from the delivery position to the reception position.

  When the holding clamp 60 holds the first electric wire C <b> 1 and the second electric wire C <b> 2, the alignment clamp 70 is located on the rear end portion 71 a of the rail 71. That is, the alignment clamp 70 is located in the vicinity of the holding clamp 60. After the rear ends of the first electric wire C1 and the second electric wire C2 are held by the holding clamp 60, the alignment clamp 70 moves forward (downward in FIG. 1). Thereby, the alignment clamp 70 aligns the 1st electric wire C1 and the 2nd electric wire C2. At this time, the holding clamp 60 has also moved forward, and has advanced to a position where the electric wire is passed to the rear transport clamp 80R.

  Next, the front transport clamp 80F and the rear transport clamp 80R move to their receiving positions. The front transfer clamp 80F simultaneously holds the front ends of the first electric wire and the second electric wire C2, and the rear transfer clamp 80R simultaneously holds the rear ends of the first electric wire C1 and the second electric wire C2. The front conveyance clamp 80F and the rear conveyance clamp 80R move to the delivery position while simultaneously holding the front end portion and the rear end portion of the first electric wire C1 and the second electric wire C2, respectively.

  After the front conveyance clamp 80F and the rear conveyance clamp 80R reach the delivery position, the front rotation clamp 90F and the rear rotation clamp 90R hold the front end portion and the rear end portion of the first electric wire C1 and the second electric wire C2, respectively. The front transfer clamp 80F and the rear transfer clamp 80R release the first electric wire C1 and the second electric wire C2, and return to the receiving position.

  As described above, the front rotary clamp 90F can be moved back and forth by the motor 103 made of an AC servomotor. The front rotary clamp 90F moves forward (in other words, in a direction away from the rear rotary clamp 90R) while simultaneously holding the first electric wire C1 and the second electric wire C2, and pulls the loosened first electric wire C1 and second electric wire C2. . The motor 103 is configured to be capable of torque control, and pulls the front rotary clamp 90F forward by a predetermined constant torque (hereinafter referred to as a predetermined torque) (see FIG. 11A). As a result, a predetermined tension T1 is applied to the first electric wire C1 and the second electric wire C2, and the first electric wire C1 and the second electric wire C2 are straightened. In addition, the value of predetermined | prescribed torque and predetermined | prescribed tension T1 is not limited at all, For example, it can set suitably according to the thickness and length of the 1st electric wire C1 and the 2nd electric wire C2.

  The front rotary clamp 90F and the rear rotary clamp 90R hold the front end and the rear end of the first electric wire C1 and the second electric wire C2, respectively, while applying the tension T1 to the first electric wire C1 and the second electric wire C2. Rotate in opposite directions. When one and the other of the rotation directions around the rotation center axis 90c are referred to as a first rotation direction R1 and a second rotation direction R2, respectively, the front rotation clamp 90F simultaneously holds the front ends of the first electric wire C1 and the second electric wire C2. While rotating in the first rotation direction R1, the rear rotation clamp 90R rotates in the second rotation direction R2 while simultaneously holding the rear ends of the first electric wire C1 and the second electric wire C2. Thereby, the 1st electric wire C1 and the 2nd electric wire C2 are twisted together. When the first electric wire C1 and the second electric wire C2 are twisted together, their apparent length, that is, the length of the twisted electric wire CT becomes shorter than the original length of the first electric wire C1 and the second electric wire C2. Therefore, the front rotation clamp 90F moves rearward while rotating in the first rotation direction R1 (see FIG. 11B). That is, the front rotation clamp 90F moves in a direction approaching the rear rotation clamp 90R while rotating in the first rotation direction R1.

  The front rotary clamp 90F and the rear rotary clamp 90R may rotate in only one direction, but in this embodiment, the front rotary clamp 90F and the rear rotary clamp 90R are controlled to rotate in the opposite direction after rotating in one direction. That is, the front rotation clamp 90F and the rear rotation clamp 90R rotate in the normal direction and then reverse (see FIG. 11C). Specifically, the front rotary clamp 90F rotates in the first rotation direction R1 while simultaneously holding the front ends of the first electric wire C1 and the second electric wire C2, as described above, and then the first electric wire C1 and the second electric wire C2. It rotates in the second rotation direction R2 while applying the predetermined tension T1. That is, the front rotary clamp 90F rotates in the second rotation direction R2 while the motor 103 performs the torque control described above. Further, as described above, the rear rotation clamp 90R rotates in the second rotation direction R2 while simultaneously holding the rear ends of the first electric wire C1 and the second electric wire C2, and then rotates in the first rotation direction R1. As a result, the first electric wire C1 and the second electric wire C2 are twisted in one direction and then twisted in the opposite direction. As a result, when the front rotary clamp 90F and the rear rotary clamp 90R subsequently release the first electric wire C1 and the second electric wire C2, the first electric wire C1 and the second electric wire C2 may be rotated in the opposite directions. Is prevented. The number of reverse rotations is not particularly limited, but here the number of reverse rotations is smaller than the number of normal rotations.

  In the present embodiment, the front rotary clamp 90F and the rear rotary clamp 90R are further controlled to rotate forward again after being reversed as described above. Specifically, the front rotary clamp 90F rotates in the second rotational direction R2 while simultaneously holding the front ends of the first electric wire C1 and the second electric wire C2 as described above, and then the first electric wire C1 and the second electric wire C2. It rotates in the first rotation direction R1 while applying the predetermined tension T1. That is, the front rotary clamp 90F rotates in the first rotation direction R1 while the motor 103 performs the torque control described above. Further, as described above, the rear rotation clamp 90R rotates in the first rotation direction R1 while simultaneously holding the rear ends of the first electric wire C1 and the second electric wire C2, and then rotates in the second rotation direction R2. As a result, the first electric wire C1 and the second electric wire C2 are twisted in one direction, then twisted in the opposite direction, and further twisted in one direction. Thereby, the adhesiveness of the 1st electric wire C1 and the 2nd electric wire C2 which were twisted together increases.

  Note that, depending on the types of the first electric wire C1 and the second electric wire C2, etc., the front rotary clamp 90F and the rear rotary clamp 90R may be rotated in the normal direction again as described above and then further reverse. That is, after the above-described operation, while the motor 103 performs the above-described torque control, the front rotation clamp 90F may rotate in the second rotation direction R2, and the rear rotation clamp 90R may rotate in the first rotation direction R1. Such forward rotation and reverse rotation may be performed several times.

  By the way, when the twisted electric wire CT is released while the front rotary clamp 90F and the rear rotary clamp 90R are applied with tension, the twisted electric wire CT contracts vigorously at the moment of releasing, and there is a possibility that the twisted electric wire CT may be violated before being collected in the tray 110. . Therefore, there is a possibility that the twisted electric wire CT cannot be collected in the tray 110 in a straight state. Therefore, in the present embodiment, next, the control device 200 ends the torque control of the motor 103, moves the front rotary clamp 90F in a direction approaching the rear rotary clamp 90R, and loosens the twisted wire CT. At this time, the control device 200 controls the position of the motor 103 so that the front rotary clamp 90F moves to a predetermined position. That is, the control device 200 positions the front rotary clamp 90F at a predetermined position.

  When the front rotary clamp 90F reaches a predetermined position, the front rotary clamp 90F and the rear rotary clamp 90R release the first electric wire C1 and the second electric wire C2. Then, the twisted first electric wire C1 and second electric wire C2, that is, the twisted electric wire CT are dropped and collected in the tray 110. Since no tension is applied to the twisted electric wire CT, the twisted electric wire CT falls downward while being straightened. Therefore, the twisted electric wire CT is collected in the tray 110 in a straight state.

  As described above, the twisted electric wire CT is manufactured from the long first electric wire C1 and the second electric wire C2.

  According to the electric wire processing device 1 according to the present embodiment, the electric wire end processing device 2 alternately discharges the first electric wires C1 and the second electric wires C2 that have been stripped of the coverings at both ends and subjected to terminal crimping. And the 1st electric wire C1 and the 2nd electric wire C2 discharged | emitted alternately from the electric wire end processing apparatus 2 are conveyed sequentially, and are twisted together by the electric wire twist apparatus 3. FIG. As a result, the twisted wire CT is manufactured automatically and continuously. According to the electric wire processing apparatus 1 according to the present embodiment, the common cutting blade 33 that cuts the first electric wire C1 and the second electric wire C2, and the common stripping of the coating on the front end portions of the first electric wire C1 and the second electric wire C2. The front stripping blade 34 and a common rear stripping blade 35 that strips the coating of the rear ends of the first electric wire C1 and the second electric wire C2. Therefore, it is not necessary to separately provide a cutting blade for the first electric wire C1 and a cutting blade for the second electric wire C2. Further, it is not necessary to separately provide a stripping blade for the first electric wire C1 and a stripping blade for the second electric wire C2. Therefore, according to the electric wire processing apparatus 1 which concerns on this embodiment, a number of parts can be reduced rather than before and size reduction is attained.

  As shown in FIG. 1, according to the electric wire processing apparatus 1 according to the present embodiment, the first electric wire C1 and the second electric wire C2 aligned by the alignment clamp 70 are moved to the first by the front transfer clamp 80F and the rear transfer clamp 80R. The first electric wire C1 and the second electric wire C2 can be conveyed in a direction intersecting with the longitudinal direction. In the present embodiment, the rail 81F and the rail 81R extend in a direction perpendicular to the rail 71. Therefore, the conveyance distance of the 1st electric wire C1 and the 2nd electric wire C2 can be shortened, and the electric wire processing apparatus 1 can be reduced in size. However, the rail 81 </ b> F and the rail 81 </ b> R need only extend in a direction intersecting with the rail 71, and do not necessarily have to extend in a direction perpendicular to the rail 71.

  The wire processing device 1 according to the present embodiment includes an intermediate clamp 50 disposed in the middle of the path of the first electric wire C1 and the second electric wire C2 from the wire end processing device 2 to the holding clamp 60. Therefore, the first electric wire C1 and the second electric wire C2 can be temporarily put on standby by the intermediate clamp 50. That is, before the first electric wire C1 and the second electric wire C2 are aligned by the alignment clamp 70, the first electric wire C1 and the second electric wire C2 sent individually are received by the intermediate clamp 50, and they are collected and held together. Can be handed over to. Therefore, until the electric wire is transferred from the holding clamp 60 to the rear conveyance clamp 80R, the electric wire held by the discharge clamp 42 is put on standby, or the holding clamp 60 receives each electric wire from the discharge clamp 42 one by one. It is not necessary for the wire end processing 2 to temporarily suspend the work until the line is completed, or even if the operation is interrupted, the interruption time can be shortened. Therefore, the twisted electric wire CT can be automatically manufactured from the long first electric wire C1 and the second electric wire C2 without significantly reducing the original processing speed of the electric wire end processing device 2. Therefore, the tact time can be shortened and the production amount per unit time of the twisted electric wire CT can be increased.

  According to the present embodiment, the intermediate clamp 50 is movable while holding the first electric wire C1 or the second electric wire C2. Therefore, the production amount per unit time of the twisted wire CT can be further increased.

  The electric wire processing apparatus 1 according to the present embodiment includes a connection mechanism including the connection pin 104 of the slider 101 and the hole 105a of the connection member 105, and the connection mechanism connects the front conveyance clamp 80F and the front rotation clamp 90F. When the motor 103 drives the front rotary clamp 90F forward or backward in this state, the front transport clamp 80F moves together with the front rotary clamp 90F. This eliminates the need for a dedicated actuator for driving the front conveyance clamp 80F forward or backward, and reduces the number of parts.

  According to the electric wire processing apparatus 1 according to the present embodiment, the front rotary clamp 90F and the rear rotary clamp 90R rotate in the opposite direction after once twisting the first electric wire C1 and the second electric wire C2. Therefore, when the front rotary clamp 90F and the rear rotary clamp 90R release the first electric wire C1 and the second electric wire C2, the first electric wire C1 and the second electric wire C2 are twisted back by rotating in the opposite direction. Is prevented. Moreover, according to the wire processing apparatus 1 which concerns on this embodiment, after rotating the front rotation clamp 90F and the rear rotation clamp 90R further in the reverse direction, it rotates in the original direction again. Thereby, the adhesiveness of the 1st electric wire C1 and the 2nd electric wire C2 improves. Therefore, according to the electric wire processing apparatus 1 which concerns on this embodiment, favorable twist electric wire CT can be obtained.
