<Attitude change mechanism>
The posture changing mechanism unit 70 is a portion that rotates the bar support unit 30 around the rotation shaft of the rotating shaft unit 36 to change the posture between the circulating posture and the receiving posture (see FIGS. 5 to 8). More specifically, the posture changing mechanism unit 70 changes the posture from the circulating posture to the receiving posture and changes the posture from the receiving posture to the circulating posture on a part of the circulation path R (here, the curved path). A part of the curved path of the circulation path R is a range including the receiving position P. That is, the receiving position P where the terminal-attached electric wire 2 is transferred to the electric wire holding bar 10 by the transfer mechanism 90 is such that the interval between adjacent electric wire holding bars 10 conveyed in the circulation path R is a linear path. It is set to a part of the curved path that is larger than that. Then, the posture changing mechanism unit 70 changes the posture of the bar support unit 30 to the receiving posture at least at the receiving position P.

  Here, the posture changing mechanism unit 70 sequentially changes the bar support unit 30 from the circulating posture to the receiving posture so that only one of the plurality of bar support units 30 located at the receiving position P is in the receiving posture. The posture is changed and the posture is changed from the receiving posture to the circulating posture (see FIG. 1). That is, the posture changing mechanism unit 70 changes the posture of the bar support unit 30 from the circulating posture to the receiving posture when moving from the position upstream of the receiving position P to the receiving position P, and from the receiving position P to the first position. When moving to the downstream position, the bar support 30 is changed from the receiving position to the circulating position.

  The posture changing mechanism unit 70 is configured to change the posture of the bar support unit 30 by transmitting a force in which the bar support unit 30 is moved by the circulation drive mechanism unit 60 as a force in the rotation direction around the rotation shaft unit 36. Has been. The posture change mechanism unit 70 includes a receiving posture change guide unit 72 and a circulation posture change guide unit 76. The receiving posture change guide unit 72 and the circulation posture change guide unit 76 are portions that are in contact with the receiving posture change transmission unit 38 or the circulation posture change transmission unit 39 so that the posture of the bar support unit 30 can be changed. The receiving posture change guide unit 72 and the circulation posture change guide unit 76 are directly or indirectly supported on the base unit 52.

  The receiving posture change guide unit 72 is provided on the moving path of the receiving posture change transmitting unit 38 of the bar support unit 30 in the circulating posture (here, on the upper side of the moving path of the rotating shaft portion 36). Further, the receiving posture change guide unit 72 is provided at a position that does not interfere with the receiving posture change transmission unit 38 of the bar support unit 30 whose posture has been changed to the receiving posture.

  Here, the receiving posture change guide unit 72 is positioned on the moving path of the receiving posture change transmission unit 38 of the bar support 30 in the circulating posture, and gradually tilts downward from the upstream side to the downstream side of the circulating route R. A contact surface 73 is provided. The contact surface 73 may be provided so as to rotate the bar support portion 30 at least until the posture maintaining biasing portion 48 biases the bar support portion 30 toward the receiving posture.

Is provided at a position where it abuts against the receiving posture change transmission unit 38. Further, the receiving posture change guide unit 72 changes the posture of the bar support unit 30 to the receiving posture until the bar support unit 30 moves to the receiving position P (including simultaneously with the movement to the receiving position P). It is configured. That is, the downstream end portion of the contact surface 73 is provided upstream from the receiving position P.

  Then, the bar support portion 30 that is circulated in the circulating posture is moved gradually while the outer peripheral surface of the receiving posture change transmitting portion 38 is in contact with the contact surface 73 of the receiving posture change guide portion 72, so that the receiving posture is gradually changed. (See FIGS. 6 and 8). The receiving posture change transmission unit 38 of the bar support unit 30 whose posture has been changed to the receiving posture passes below the receiving posture change guide unit 72 without interfering with the receiving posture change guide unit 72.

  The circulation posture change guide unit 76 is provided on the movement path of the circulation posture change transmission unit 39 of the bar support unit 30 in the receiving posture (here, below the movement path of the rotating shaft portion 36). In addition, the circulation posture change guide unit 76 is provided at a position that does not interfere with the circulation posture change transmission unit 39 of the bar support unit 30 whose posture has been changed to the circulation posture. Here, the circulation posture change guide portion 76 is formed in a roller shape and is supported so as to be rotatable with respect to a support piece erected on the base portion 52. More specifically, the circulation posture change guide unit 76 is supported so as to be rotatable around an axis along the inner and outer directions of the circulation path R.

It is provided more upstream.

  Then, the bar support portion 30 circulated and moved in the receiving posture gradually changes its posture to the circulation posture by moving the circulation posture change transmission unit 39 while contacting the outer peripheral surface of the circulation posture change guide unit 76. (See FIG. 8). The circulation posture change transmission unit 39 of the bar support unit 30 whose posture has been changed to the circulation posture passes above the circulation posture change guide unit 76 without interfering with the circulation posture change guide unit 76.

<Operation of wire holding bar transport device>
Next, operation | movement of the electric wire holding bar conveyance apparatus 20 is demonstrated.

  First, in the initial state, it is assumed that the wire holding bars 10 are supported by the plurality of bar support portions 30, respectively. In this state, the plurality of electric wire holding bars 10 are conveyed along the circulation path R by driving the circulation drive mechanism 60.

  When any one of the wire holding bars 10 is disposed at the receiving position P, the conveyance is temporarily stopped. Here, when the wire holding bar 10 is moved from the position one upstream of the receiving position P to the receiving position P, the posture changing mechanism 70 changes the posture of the bar support 30 from the circulation posture to the receiving posture. Is done.

  In this state, the transfer mechanism portion 90 transfers the terminal-attached electric wire 2 manufactured by the cutting machine 80 to the electric wire holding bar 10 supported by the bar support portion 30 in the receiving posture disposed at the receiving position P. Is done. Then, when the preset number and type of terminal-attached electric wires 2 are transferred to the electric wire holding bar 10, one upstream side bar support portion 30 (electric wire holding bar 10) is driven by the circulation drive mechanism 60. Are arranged at the receiving position P, the plurality of wire holding bars 10 are conveyed. Here, the bar support portion 30 that is moved from the receiving position P to a position downstream of the receiving position P is changed in posture from the receiving position to the circulating position.

  And the electric wire 2 with a terminal 2 is transferred with respect to the electric wire holding bar 10 arrange | positioned in the receiving position P similarly to the above.

  Here, when the terminal-attached electric wire 2 is transferred once to the receiving position P, the transfer may be performed on all of the plurality of electric wire holding portions 12 of the electric wire holding bar 10 or may be made to make a plurality of turns. You may carry out whenever it stops at the receiving position P. In the latter case, each time the electric wire holding bar 10 is stopped at the receiving position P, different types of electric wires 2 with terminals may be transferred in sequence.

  When the transfer of the terminal-attached electric wire 2 to the electric wire holding bar 10 supported by each bar support portion 30 is completed, the electric wire holding bar 10 is taken out from the bar support portion 30. Thereby, the electric wire 2 with a terminal of the electric wire holding | maintenance bar | burr 10 can obtain the electric wire 2 with a different kind or the same kind. If a plurality of different types of terminal-attached electric wires 2 constituting the temporary bundling are held in one electric wire holding bar 10, a plurality of electric wire holding bars 10 holding a plurality of terminals-attached electric wires 2 in a temporary bundling unit are obtained. be able to.

  According to the electric wire holding bar transport device 20 configured as described above, the plurality of bar support portions 30 are configured such that the end portions of the electric wires 2 with terminals supported by the electric wire holding portions 12 face upward along the vertical direction. The posture can be changed between a circulation posture for supporting the electric wire holding bar 10 and a receiving posture for supporting the electric wire holding bar 10 in a posture where the electric wire end portion of the electric wire 2 with terminal is in a sleeping state. The posture changing mechanism unit 70 is configured to rotate around the rotation axis of the rotary shaft part 36 in a part of the circulation path R to change the posture from the circulating posture to the receiving posture and to change the posture from the receiving posture to the circulating posture. Therefore, the entanglement between the terminal-attached electric wires 2 held by the adjacent electric wire holding bars 10 can be suppressed, and interference between the terminal-attached electric wires 2 and the electric wire holding bars 10 can also be suppressed. Thereby, the some electric wire holding bar 10 can be arranged in a narrow space | interval on the circulation path | route R, and the some electric wire holding bar 10 can be conveyed by space saving as much as possible.

  In addition, the posture changing mechanism unit 70 transmits the force that the bar support unit 30 is moved along the circulation path R by the circulation drive mechanism unit 60 as the force in the rotation direction around the rotation axis of the rotation shaft unit 36. Since the support portion 30 is configured to change the posture, the configuration of changing the posture of the bar support portion 30 can be realized without providing a new drive source.

  In addition, the bar support unit 30 has a receiving posture change transmission unit 38 that protrudes to the side of the rotating shaft in a direction orthogonal to the rotating path R and the rotating shaft of the rotating shaft 36 in the circulating posture, and the circulation path R and A circulation posture change transmission unit 39 that projects to the side of the rotation shaft in a direction orthogonal to the rotation axis of the rotation shaft portion 36, and the posture change mechanism unit 70 transmits the received posture change transmission of the bar support unit 30 in the circulation posture. A receiving posture change guide unit 72 provided on the movement path of the unit 38 and a circulation posture change guide unit 76 provided on the movement route of the circulation posture change transmission unit 39 of the bar support unit 30 in the receiving posture. When the bar support unit 30 changes its posture from the circulation posture to the reception posture by the receiving posture change transmission unit 38 coming into contact with the receiving posture change guide unit 72 as the bar support unit 30 is circulated by the circulation drive mechanism 60. Both Can circulation position change transmission 39 bar support 30 is altered in attitude in circulation position from the receiving position by abutting the circulation position changing guide portion 76. In this way, the posture of the bar support portion 30 can be changed with a simple configuration.

  In addition, since the circulation path R is set to a path including a straight path, terminals that are held by the adjacent wire holding bars 10 even in a straight path where the distance between the wire holding bars 10 is smaller than that of the curved path. Tangles between the attached electric wires 2 can be suppressed, and the plurality of electric wire holding bars 10 can be transported in a smaller space. That is, the occupation area when conveying the predetermined number of electric wire holding bars 10 can be further reduced.

  In addition, although the dimension of the electric wire holding bar 10 itself in the direction along the circulation path R is smaller in the receiving posture state than in the state where the bar support portion 30 is in the circulating posture, the electric wire with terminal 2 is held by the electric wire holding bar 10. The overall dimensions of the stagnation state are smaller in the circulating posture state than in the receiving posture state of the bar support 30.

  Further, since the circulation path R includes a pair of semicircular arc-shaped curved paths and a pair of linear paths connecting the pair of curved paths, the plurality of electric wire holding bars 10 can be further transported in a space-saving manner.

  In addition, the posture changing mechanism unit 70 sequentially changes the posture from the circulating posture to the receiving posture so that only one of the plurality of bar support portions 30 moved by the circulation driving mechanism unit 60 is in the receiving posture. In order to change the posture from the receiving posture to the circulating posture, only the bar support portion 30 disposed at the position where the terminal-attached electric wire 2 is transferred with respect to the electric wire holding bar 10 is set to the receiving posture, and the adjacent electric wire holding bars 10 are arranged. The entanglement of the terminal-equipped electric wire 2 held by the wire can be more reliably suppressed.

  So far, the circulation path R has been described as an example including a pair of semicircular arc-shaped curved paths and a pair of linear paths connecting the pair of curved paths. However, the circulation path R may be another annular path. Further, although the example in which the receiving position P is set as a part of the curved path has been described, the receiving position P may be set as a part of the straight path.

  In addition, the posture changing mechanism unit 70 is not limited to a configuration that changes the posture of only one bar support unit 30 moved to the receiving position P to the receiving posture. That is, the posture changing mechanism unit 70 may be configured to change the posture of the bar support unit 30 moved to a part of the circulation path R including the receiving position P to the receiving posture. However, it is preferable that the electric wire holding bar 10 whose posture is changed to the receiving posture is located in a curved path in the circulation path R where the distance between the electric wire holding bars 10 is larger than that of the linear path. More preferably, it is better to change the posture of only one bar support portion 30 moved to the receiving position P to the receiving posture, and the entanglement of the wire 2 with terminal supported by the adjacent wire holding bar 10 is more reliably suppressed. can do.

  In addition, the posture changing mechanism unit 70 is not limited to the configuration described above, and may be any device that can change the posture of the bar support unit 30 between the circulating posture and the receiving posture. For example, the posture change mechanism unit may be configured such that a receiving posture change guide unit and a circulation posture change guide unit are provided on one of the upper side and the lower side of the rotary shaft of the rotary shaft unit 36. That is, the bar support portion is provided with a receiving posture change transmitting portion that protrudes above the rotating shaft portion 36 in a circulating posture and a circulating posture change transmitting portion that protrudes above the rotating shaft portion 36 in a receiving posture. When the unit abuts on a receiving posture change guide unit or a circulating posture change guide unit provided on the upper side of the rotation shaft portion 36, the posture is changed from the circulating posture to the receiving posture and from the receiving posture to the circulating posture. Among the transmission parts of the circulation path R, those that are moved toward the downstream side of the circulation path R around the rotation axis of the rotation shaft part 36 by the posture change guide part are inclined and projecting to the downstream side. Further, it is preferable that the posture change guide portion with which the transmission portion abuts is set at a relatively gentle inclination angle.

  Further, for example, the following configuration can be adopted as the posture changing mechanism unit 70. That is, the bar support portion is provided with a transmission portion that projects to one side of the rotation shaft in a direction perpendicular to the circulation path R and the rotation shaft of the rotation shaft portion 36 in the circulation posture. Further, the bar support portion and the support base 42 are connected by an urging member that urges the bar support portion in the rotation direction to change the posture to the circulation posture. In addition, a posture change guide unit is provided on the moving path of the transmission unit. The posture change guide unit includes a posture change surface provided on the movement path of the transmission unit of the bar support unit in the circulation posture and intersecting the movement route, and a bar support portion at the receiving position where the posture is changed to the reception posture. And a regulating surface provided along the extending surface of the circulation path R. Then, as the bar support portion is moved to the receiving position, the transmission portion comes into contact with the posture change surface and the bar support portion changes its posture, and at the reception position, the transmission portion comes into contact with the regulation surface and the bar support portion The change of posture to the circulating posture is regulated. Furthermore, when the transmission portion is moved to a position where the transmission portion is not in contact with the regulation surface, the posture of the bar support portion is changed to the circulation posture by the biasing force of the biasing member.

  In addition, the posture changing mechanism unit may be configured to change the posture by rotationally driving the bar support unit 30 moved to the receiving position P by a motor.

  As described above, the electric wire holding bar transport device 20 has been described in detail, but the above description is an example 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.
