<Operation of wire transfer device>
Next, the transfer operation of the wire transfer device 10 will be described. Here, the receiving process, the conveying process, and the setting process of the terminal-attached electric wire 2 will be described separately.

  As an initial state, it is assumed that a pair of wire conveyance gripping portions 79 that grip the wire ends on both sides of the terminal-attached wire 2 manufactured by the cutting and crimping device 70 are arranged at the receiving position P1. In addition, it is assumed that the wire holding bar 80 having the wire holding portion 82 where the terminal-attached wire 2 is not held is arranged at the set position P2 by the wire holding bar conveyance device 90. The pair of first reciprocating drive mechanism portions 32 support the first advance / retreat drive mechanism portions 26 above the electric wire conveyance gripping portions 79 arranged at the receiving position P1, and the pair of second reciprocating drive mechanism portions 52 It is assumed that each second advance / retreat driving mechanism 46 is supported above two predetermined electric wire holding portions 82 of the electric wire holding bar 80 arranged at the set position P2. Further, the pair of first advance / retreat drive mechanism portions 26 and the pair of second advance / retreat drive mechanism portions 46 move the first gripping mechanism portion 22 and the second gripping mechanism portion 42 to the first retracted position C1 or the second retracted position C2. It shall be supported (see FIG. 8). Further, the pair of gripping pieces 23 of the first gripping mechanism portion 22 are open, and the pair of gripping pieces 23 of the second gripping mechanism portion are closed with the wire end portion of the terminal-attached electric wire 2 sandwiched therebetween. And

  In the receiving process of the first transfer mechanism unit 20, first, the delivery lifting drive unit 28 is moved downward by the indirect lifting drive unit 27 (see FIG. 7). As a result, the first gripping mechanism 22 is moved from the first retracted position C1 to the preliminary retracted position B.

  Next, the 1st holding | grip mechanism part 22 is moved down by the delivery raising / lowering drive part 28 (refer FIG. 7). As a result, the first gripping mechanism 22 is moved from the preliminary retracted position B to the advanced position A.

  Next, in the first gripping mechanism section 22, the pair of gripping pieces 23 are moved close (closed) by the opening / closing drive section 24 (see FIG. 12). At this time, the distance between the pair of gripping pieces 23 is set to be the same as or smaller than the diameter of the wire end of the terminal-attached electric wire 2 (here, slightly smaller). Thereby, the 1st holding | grip mechanism part 22 hold | grips the electric wire edge part of the electric wire 2 with a terminal hold | gripped by the electric wire conveyance holding part 79. FIG. And in this state, the electric wire conveyance holding part 79 is made to release | grip the electric wire 2 with a terminal.

  Next, the first lifting / lowering drive unit 28 moves the first gripping mechanism unit 22 upward. As a result, the first gripping mechanism 22 is moved from the advance position A to the preliminary retreat position B.

  Next, the delivery lifting drive unit 28 is moved up by the indirect lifting drive unit 27. As a result, the first gripping mechanism 22 is moved from the preliminary retracted position B to the first retracted position C1.

  With the above operation, the receiving process of the terminal-attached electric wire 2 by the first transfer mechanism unit 20 is completed.

  During the receiving process of the terminal-attached electric wire 2 by the first transfer mechanism section 20, the second transfer mechanism section 40 executes a setting process of the terminal-attached electric wire 2.

  First, the delivery raising / lowering driving unit 48 is moved downward by the indirect raising / lowering driving unit 47 (see FIG. 6). As a result, the second gripping mechanism portion 42 is moved from the second retracted position C2 to the preliminary retracted position B.

  Next, the 2nd holding | grip mechanism part 42 is moved down by the delivery raising / lowering drive part 48 (refer FIG. 6). As a result, the second gripping mechanism portion 42 is moved from the preliminary retracted position B to the advanced position A. The terminal-attached electric wire 2 held by the second holding mechanism portion 42 is held by the electric wire holding portion 82 of the electric wire holding bar 80. More specifically, in the electric wire with terminal 2, a part of the end portion of the electric wire that crosses the inside of the opposing portions of the gripping piece 43 by the advancing operation of the pair of gripping pieces 43 is arranged on the inner side. It is clamped by a pair of elastic clamping pieces 83 of the holding portion 82 (see FIGS. 5 and 11).

  Next, in the second gripping mechanism portion 42, the pair of gripping pieces 43 are moved apart (opened) by the opening / closing drive portion 44. At this time, the distance between the pair of gripping pieces 43 is set to be larger than the diameter of the end portion of the terminal-attached electric wire 2. Thereby, the 2nd holding | grip mechanism part 42 cancels | releases the electric wire edge part of the electric wire 2 with a terminal.

  Next, the second lifting mechanism unit 42 is moved up by the delivery lifting / lowering drive unit 48. As a result, the second gripping mechanism portion 42 is moved from the advance position A to the preliminary retracted position B.

  Next, the delivery raising / lowering drive unit 48 is moved up by the indirect raising / lowering drive unit 47. As a result, the second gripping mechanism portion 42 is moved from the preliminary retracted position B to the second retracted position C2.

  With the above operation, the setting process of the terminal-attached electric wire 2 by the second transfer mechanism 40 is completed. 6 and 7 show a state where the first gripping mechanism 22 and the second gripping mechanism 42 are alternately moved to the advance position A and the first retracted position C1 or the second retracted position C2. This is shown for convenience of explanation. Actually, both the first gripping mechanism portion 22 and the second gripping mechanism portion 42 are advanced positions in the region on the receiving position P1 side or the region on the set position P2 side, respectively. Moved to A.

  After the receiving process of the first transfer mechanism unit 20 and the setting process of the second transfer mechanism unit 40 are completed, the transport process of the first transfer mechanism unit 20 and the second transfer mechanism unit 40 is executed.

  In other words, the first reciprocating drive mechanism 32 moves the first advance / retreat drive mechanism 26 from the receiving position P1 side area to the set position P2 side area in the first path R1. At the same time, the second reciprocating drive mechanism 52 moves the second advance / retreat drive mechanism 46 from the set position P2 side area to the receiving position P1 side area in the second path R2.

  Here, when the first advancing / retreating drive mechanism unit 26 and the second advancing / retreating drive mechanism unit 46 pass each other, the first gripping mechanism unit 22 and the second gripping mechanism unit 42 are respectively in the first retracted position C1 or the second retracted position. Passing sideways in the state of position C2 (see FIG. 8).

  In addition, if at least one of the first gripping mechanism unit 22 and the second gripping mechanism unit 42 is moved to the first retracted position C1 or the second retracted position C2, the first advance / retreat drive mechanism unit 26 and the second The two-way drive mechanism 46 can pass by. In a state where the first gripping mechanism 22 is in the first retracted position C1 and the second gripping mechanism 42 is in the preliminary retracted position B, the second gripping mechanism 42 passes under the first gripping mechanism 22 (see FIG. 6). The state is a state in which the delivery raising / lowering driving unit 48 is moved to the lowered position by the indirect raising / lowering driving unit 47 and the second gripping mechanism unit 42 is moved to the lowered position by the delivery raising / lowering driving unit 48. Further, in a state where the first gripping mechanism unit 22 is in the preliminary retracted position B and the second gripping mechanism unit 42 is in the second retracted position C2, the first gripping mechanism unit 22 and the second gripping mechanism unit 42 are mutually connected. Pass by the side (see Figure 7).

  In addition, when the terminal of the electric wire 2 with a terminal is comparatively long, when the space | interval of the 1st transfer mechanism part 20 and the 2nd transfer mechanism part 40 is comparatively narrow, etc., the 1st holding | grip mechanism part 22 and One of the second gripping mechanism portions 42 that grips the terminal-attached electric wire 2 and moves from the region on the receiving position P1 side to the region on the set position P2 side is disposed at the preliminary retracted position B, and the other is the first retracted position. The first gripping mechanism portion 22 and the second gripping mechanism portion 42 may be alternately moved between the region on the receiving position P1 side and the region on the set position P2 side in the state where the C1 or the second retracted position C2 is disposed. (See FIGS. 6 and 7).

  That is, in the receiving process and the setting process, in the first transfer mechanism part 20 and the second transfer mechanism part 40, at least one of the first gripping mechanism part 22 and the second gripping mechanism part 42 is in the first retraction position C1 or the second transfer mechanism part 42. As long as it has been moved to the second retracted position C2, the other does not have to be moved upward from the preliminary retracted position B.

  And a pair of 1st reciprocating drive mechanism parts 32 are the electric wire holding | maintenances which are different from the electric wire holding part 82 set last time among the electric wire holding bars 80 in which each 1st holding | grip mechanism part 22 has been arrange | positioned in the setting position P2. The first advancing / retracting drive mechanism unit 26 is moved to a position disposed above the unit 82. In addition, the pair of second reciprocating drive mechanism units 52 includes the second advancing / retreating drive mechanism unit 46 to a position where each second gripping mechanism unit 42 is disposed above the pair of electric wire conveyance gripping units 79 disposed at the receiving position P1. Move.

  Upon completion of the transporting process, the next step is to execute the setting process of the terminal-attached electric wire 2 received in the receiving process by the first transfer mechanism unit 20, and the second transfer mechanism part 40 executes the receiving process of the terminal-attached electric wire. To do.

  That is, in the first transfer mechanism unit 20, each first gripping mechanism unit 22 is moved to the advanced position A by the pair of first advance / retreat drive mechanism units 26 and is held by the wire holding unit 82 of the wire holding bar 80. And the holding | grip of the electric wire edge part of the electric wire 2 with a terminal by each 1st holding | grip mechanism part 22 is cancelled | released, and each 1st holding | grip mechanism part 22 is moved to the 1st evacuation position C1 by a pair of 1st advance / retreat drive mechanism part 26 again. Let Thereby, the setting process of the electric wire 2 with a terminal by the 1st transfer mechanism part 20 is completed.

  Further, in the second transfer mechanism section 40, the second gripping mechanism sections 42 are moved to the advanced positions A by the pair of second advance / retreat driving mechanism sections 26, and are gripped by the wire conveyance gripping section 79 by the second gripping mechanism section 42. The end portion of the terminal-attached electric wire 2 is gripped. Then, the second gripping mechanism portions 42 are moved again to the second retracted position C2 by the pair of second advance / retreat driving mechanism portions 46 again. Thereby, the receiving process of the electric wire 2 with a terminal by the 2nd transfer mechanism part 20 is completed.

  Next, the transport process of the first transfer mechanism unit 20 and the second transfer mechanism unit 40 is executed. In other words, the first reciprocating drive mechanism 32 moves the first advance / retreat drive mechanism 26 from the set position P2 side area to the receiving position P1 side area in the first path R1. At the same time, the second reciprocating drive mechanism 52 moves the second advance / retreat drive mechanism 46 from the receiving position P1 side area to the set position P2 side area in the second path R2.

  By repeating the above steps, the terminal-attached electric wire 2 can be transferred continuously. When the electric wire holding bar 80 is full, the electric wire holding bar conveying device 90 moves the next electric wire holding bar 80 to the set position P2 and transfers the terminal-attached electric wire 2 to the electric wire holding bar 80. Good.

  According to the wire transfer device 10 according to the embodiment, the first reciprocating drive mechanism unit 32 and the second reciprocating drive mechanism unit 52 are configured such that at least one of the first gripping mechanism unit 22 and the second gripping mechanism unit 42 is the first. In the state moved to the retracted position C1 or the second retracted position C2, the first advance / retreat drive mechanism unit 26 and the second advance / retreat drive mechanism unit 46 are alternately arranged in the receiving position P1 side area and the set position P2 side area. In order to move, while one of the first gripping mechanism portion 22 and the second gripping mechanism portion 42 is performing the operation of receiving the terminal-attached electric wire 2 on the receiving position P1 side, the other is the electric wire holding bar 80 on the set position P2 side. The operation | movement which sets the electric wire 2 with a terminal to the electric wire holding part 82 of this can be performed. Thereby, compared with the case where only one transfer mechanism part is provided, the electric wire 2 with a terminal can be transferred at double speed, and the transfer efficiency of the electric wire 2 with a terminal can be improved more. .

  Moreover, since the advance positions A1 of the first gripping mechanism portion 22 and the second gripping mechanism portion 42 are the same position, the terminal-attached electric wire 2 can be used without changing the configuration of the cutting and crimping device 70 and the wire holding bar transport device 90. The transfer efficiency can be improved.

  Further, the second advance / retreat drive mechanism 46 moves the second gripping mechanism 42 from the advance position A on the first movement region R1 where the first advance / retreat drive mechanism 26 is moved. According to the configuration in which the second gripping mechanism portion 42 is moved along a path including a straight path that is obliquely upward between the second movement region R2 and the second retraction position C2 that is obliquely above the advance position A. Can be shortened. Moreover, it contributes to space saving of the wire transfer device 10 itself.

  Further, the second advancing / retreating drive mechanism unit 46 moves the second gripping mechanism unit 42 up and down, and the delivery lifting and lowering drive unit 48 moves the lowering position on the first movement region R1 and on the second movement region R2. With the configuration having the indirect lift drive unit 47 that moves up and down diagonally between the lift position and the lift position obliquely above the drop position, the delivery lift drive section 48 is moved to the drop position on the first movement region R1. The configuration to be made can be simplified. That is, the movement in the vertical direction and the movement in the horizontal direction can be realized by one drive unit, and the equipment cost of the wire transfer device 10 can be reduced and the space can be saved.

  Further, the second gripping mechanism portion 42 passes under the first gripping mechanism portion 22 moved to the first retraction position C1 in a state where the delivery lifting / lowering driving portion 48 is moved to the lowered position by the indirect lifting / lowering driving portion 47. According to the configuration set to be possible, if the second gripping mechanism unit 42 is moved up by the delivery lifting / lowering drive unit 48, the first gripping mechanism unit 22 and the first gripping mechanism unit 22 can be connected to each other even if the delivery lifting / lowering drive unit 48 remains in the lowered position. 2 The gripping mechanism portion 42 can be moved between the area on the receiving position P1 side and the area on the set position P2 side. Thereby, the drive number of the indirect raising / lowering drive part 47 can be reduced, and it contributes to reduction of drive cost and prolongation of lifetime. Moreover, the clearance for suppressing the interference of the part which protrudes to the side of the held electric wire 2 with a terminal compared with the case where the 1st holding | grip mechanism part 22 and the 2nd holding | grip mechanism part 42 mutually pass each other. Is not required to be provided on the side of the first gripping mechanism portion 22 and the second gripping mechanism portion 42, which contributes to space saving of the wire transfer device 10 itself.

  Further, the first reciprocating drive mechanism portion 32 and the second reciprocating drive mechanism portion 52 divide the first advance / retreat drive mechanism portion 26 and the second advance / retreat drive mechanism portion 46 into an area on the receiving position P1 side and an area on the set position P2 side. Therefore, the receiving operation and the setting operation of the terminal-attached electric wire 2 can be simultaneously advanced to further improve the transfer efficiency.

  So far, the first transfer mechanism unit 20 has been described with an example in which the first gripping mechanism unit 22 is moved only in the vertical direction, but the first gripping mechanism unit 22 is tilted like the second transfer mechanism unit 40. It may be configured to move in the direction. For example, the 1st transfer mechanism part 20 may be comprised so that the delivery raising / lowering drive part 28 may be moved to the diagonal direction by the indirect raising / lowering drive part arrange | positioned along the diagonal direction.

  Moreover, although the 2nd transfer mechanism part 40 was demonstrated in the example which moves the delivery raising / lowering drive part 48 in the diagonal direction by the indirect raising / lowering drive part 47, it is not restricted to this. That is, the second transfer mechanism unit 40 only needs to be able to move the second gripping mechanism unit 42 between the advanced position A and the second retracted position C2, and the delivery lifting / lowering drive unit 48 in the horizontal direction. You may have the indirect raising / lowering drive part to move. Moreover, the 2nd transfer mechanism part 40 may be comprised so that an indirect raising / lowering drive part may move the delivery raising / lowering drive part 48 to a perpendicular direction. However, in this case, it is necessary to adopt the configuration of the first advance / retreat drive mechanism that moves the first gripping mechanism 22 in an oblique direction or a horizontal direction.

  Moreover, although the 1st reciprocating drive mechanism part 32 and the 2nd reciprocating drive mechanism part 52 demonstrated by the example comprised by a guide rail, a movement base, a pair of pulley, a motor, and a drive belt, it is not restricted to this. . That is, the first reciprocating drive mechanism portion 32 and the second reciprocating drive mechanism portion 52 move the first advance / retreat drive mechanism portion 26 or the second advance / retreat drive mechanism portion 46 along the first movement region R1 or the second movement region R2. Any mechanism that can move linearly may be used, and a linear actuator such as an air cylinder may be used.

  Moreover, although operation | movement of the electric wire transfer apparatus 10 has been demonstrated in the example in which the receiving process or setting process of the 1st transfer mechanism part 20 and the setting process or receiving process of the 2nd transfer mechanism part 40 are advanced simultaneously. The timings of both processes may be shifted. That is, the first transfer mechanism unit 20 and the second transfer mechanism unit 40 are transferred by one transfer mechanism unit if the first gripping mechanism unit 22 and the second gripping mechanism unit 42 operate so as to pass each other. The transfer efficiency can be improved as compared with the case of performing. From the viewpoint of improving transfer efficiency, the first transfer mechanism unit 20 and the second transfer mechanism unit 40 are set to the region on the receiving position P1 side of the first holding mechanism unit 22 and the second holding mechanism unit 42. It is preferable that the reciprocation between the area on the position P2 side is alternately performed, and the setting process or the receiving process is performed simultaneously.

  Although the electric wire transfer device 10 has been described in detail as described above, 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.
