In order to improve the processing efficiency, there has been proposed an automatic wire exchange device that can automatically exchange wires (see, for example, Patent Document 1).

  That is, according to the automatic wire changing apparatus disclosed in Patent Document 1, the replacement wire is gripped in advance over each clamp portion of the replacement wire supply mechanism. Then, when the predetermined processing by the terminal crimping device is completed and the wire is replaced, the gripping of the wire by the front clamp of the wire gripping mechanism is released and the pair of split holding means are operated to be separated from each other. The holding release posture is assumed.

  In this state, the pair of wire feeding sections of the machined wire feeding / discharging mechanism is driven in reverse, and the reverse driving causes the wires to be ejected vigorously in the direction opposite to the wire feeding direction. Discharged upstream in the feed direction.

  Thereafter, the wire gripping mechanism is moved to a predetermined position, and the replacement wire gripped by the clamp portion of the replacement wire supply mechanism is guided between the pair of split holding means in the wire gripping mechanism. And it is set as the electric wire guide attitude | position which the paired division | segmentation holding | maintenance means operated close to each other, and the state which hold | maintained the electric wire so that supply was possible by both division | segmentation holding means is obtained. Thereafter, the holding of the electric wire by each clamp portion is released, and the replacement electric wire is transferred from each clamp portion to each divided holding means.

  In this way, the wire gripping mechanism to which the replacement wire has been transferred is returned to the wire feeding position where the pair of wire feeding units are separated in advance and waiting, and in this state the pair of wire feeding units Is operated so that the downstream end of the wire in the wire feeding direction is sandwiched between the two wire feeding portions.

  In this state, when the pair of wire feeding units is driven to rotate forward, the wires are sequentially fed along the wire feeding direction, and inside the cylindrical front clamp disposed downstream in the wire feeding direction. The wire replacement work was completed by inserting and guiding the wire, and thereafter the wire was processed in the same manner.

Each guide cylinder 95 is configured to be slidably guided.

  Then, as shown by the phantom line in FIG. 8, the wire gripping mechanism 14 is based on the wire feeding position A where the held wire 10 is fed / discharged by the processing wire feeding / discharging mechanism 11 and the processing wire feeding / discharging mechanism 11. The wire is retracted from the wire feeding position A to one side, and can be moved to a replacement wire delivery position B to which the replacement wire 10 is delivered by a pair of clamp portions 92.

  On the other hand, the clamp portion 92 has a grip release posture of the front clamp 2 and a hold release posture of the pair of wire holding means 49 and 50 as shown in FIG. 4 at the exchange wire delivery position B of the wire gripping mechanism 14. With the portion along the wire feeding direction P opened upward, the replacement wire supply position D for supplying and transferring the replacement wire 10 and the replacement wire 10 indicated by the upper solid line are gripped. It is possible to move up and down (reciprocate) with the standby position E of the exchanged electric wire to wait, and the raising and lowering position of the clamp portion 92 is located on one side by a predetermined distance from the electric wire feeding path through which the electric wire 10 is fed. It is structured.

  Next, the exchange operation | movement at the time of line | wire type exchange of the electric wire 10 by the exchange electric wire supply mechanism 87 concerning this embodiment is demonstrated.

  When the predetermined processing by the terminal crimping apparatus 1 is completed and the electric wire 10 is replaced, the electric wire gripping mechanism 14 is located at the electric wire feeding position A, and until just before that, as shown in FIG. The electric wire 10 in use is sandwiched between the feeding belts 30 and 31 of the pair of electric wire feeding sections, and is gripped by the front clamp 2 on the downstream side in the electric wire feeding direction P, and on the upstream side in the electric wire feeding direction P. The wire holding means 49 and 50, and the fixed roller 51 and the movable roller 52 hold the wire. Further, the replacement electric wire 10 is held in advance over the clamp portions 92 of the replacement electric wire supply mechanism 87.

  Next, when an electric wire exchange signal is input by operating an appropriately provided switch, the operation cylinder 57 is actuated first to release the grip of the electric wire 10 by the front clamp 2 and take the grip release posture. In this state, in order to remove the terminal portion crimped to the tip end portion of the electric wire 10, the electric wire 10 is sent out by a small amount by the forward rotation driving of both the feeding belts 30 and 31 in the processing electric wire supply / exhaust mechanism 11, so The tip is cut.

  Thereafter, the support base 38 is separated by the operation of the operation cylinder 43. Here, the electric wire holding means 49 and 50 are held and released from each other, and the link mechanism engaging portion 38a and the support base engaging portion 76c are engaged with each other as the support base 38 is separated. As a result, the link mechanism 74 is operated, the movable roller 52 is separated from the fixed roller 51, the movable nozzle guide 69 is separated from the fixed nozzle guide 68, and the shutter 60 is opened, as shown in FIG. As a result, a state in which the holding of the electric wire 10 is released is obtained.

  In this state, the pair of wire feeding sections 32 and 33 are driven in reverse, and the electric wire 10 is vigorously discharged in the direction opposite to the wire feeding direction P by the reverse driving of both the sending belts 30 and 31, The part is discharged from the wire gripping mechanism 14 to the upstream side in the wire feeding direction P.

  After the electric wire 10 is discharged, the electric wire gripping mechanism 14 is moved to the replacement electric wire delivery position B by the front moving means 8.

  When the wire gripping mechanism 14 moves to the replacement wire delivery position B, the operation cylinder 89 of the replacement wire supply mechanism 87 is activated, and each clamp portion 92 that grips the replacement wire 10 by the operation of the operation cylinder 89 supplies the replacement wire. The lowering operation is performed to the position D.

  When each clamp part 92 moves to the replacement electric wire supply position D, the electric wire 10 located between both the clamp parts 92 is connected between both the electric wire holding means 49 and 50 of the electric wire gripping mechanism 14, between the fixed roller 51 and the movable roller 52, The wire guide blocks 65a and 65b are relatively guided in the exchange wire supply groove 59 between the fixed claw 56 and the movable claw 58 and between the fixed nozzle guide 68 and the movable nozzle guide 69 to be supplied.

  In this state, the movable claw 58 is moved in the direction of the fixed claw 56 by the operation of the operation cylinder 57 to grip the electric wire 10. Next, when the support base 38 is approached by the operation of the operation cylinder 43, both the wire holding means 49, 50 are brought into the wire guide posture in which the support base 38 is operated to be close to each other. Since the engagement between the mechanism engaging portion 38a and the support base engaging portion 76c is released and the link mechanism 74 is returned to the initial state, the electric wire 10 is gripped between the fixed roller 51 and the movable roller 52, A state in which the end portion of the electric wire 10 protrudes from the nozzle opening between the fixed nozzle guide 68 and the movable nozzle guide 69 of the electric wire nozzle portion 67 through both the electric wire guide blocks 65a and 65b and in the exchange electric wire supply groove 59. That is, a state where the electric wire 10 is held so as to be fed is obtained. In this state, the gripping of the electric wire 10 by each clamp portion 92 is released. Here, the replacement wire 10 is transferred from each clamp portion 92 to the wire gripping mechanism 14.

  When the electric wire 10 is delivered to the electric wire gripping mechanism 14, the electric wire gripping mechanism 14 is moved from the replacement electric wire delivery position B in a direction opposite to the electric wire feeding position A by a predetermined distance. The electric wire 10 is detached from each clamp part 92 by this retreat position movement. After the wire gripping mechanism 14 is moved to the retracted position, the clamp portions 92 are raised and returned to the exchange wire standby position E at the initial position by the operation of the operation cylinder 89 or the like. Further, the next replacement electric wire 10 may be appropriately held by each clamp portion 92 returned to the replacement electric wire standby position E.

  When each clamp part 92 moves to the exchange electric wire standby position E, the electric wire feeding position A in which the pair of electric wire feeding parts 32 and 33 are waiting in the separated state of the two feeding belts 30 and 31 that are separated in advance. When the wire gripping mechanism 14 that has been moved to the retracted position and is on standby is operated to move, the delivered wire 10 is positioned between the delivery belts 30 and 31 in the pair of wire feeding units 32 and 33. can get.

  Next, the pair of wire feeders 32 and 33 are operated to approach from this state, and the replacement work of the wire 10 is completed.

  In this state, when the pair of wire feeding units 32 and 33 are driven in the normal direction, the electric wires 10 are sequentially fed along the wire feeding direction P by the forward driving of both the feeding belts 30 and 31. As described above, the electric wire 10 can be processed.

  The present embodiment is configured as described above, and when the electric wire 10 is exchanged, the electric wires 10 for replacement previously grasped by the clamp portions 92 of the exchange electric wire supply mechanism 87 are separated from each other by the electric wire grasping mechanism 14. Drop from above between the pair of wire holding means 49, 50, between the fixed roller 51 and the movable roller 52, between the wire guide blocks 65a, 65b, in the replacement wire supply groove 59, and between the fixed nozzle guide 68 and the movable nozzle guide 69. Therefore, after passing to the pair of wire holding means of the wire gripping mechanism once as before, the wires passed to the pair of wire holding means are processed. Compared with the system that feeds in the wire feeding direction by the wire feeding / discharging mechanism and guides it to the front clamp, the wire can be attached more easily and in a shorter time. Can.

  Moreover, for the front clamp 2, the replacement electric wire 10 is delivered through the opening of the replacement electric wire supply groove 59, and the electric wire is clogged as in the case where the electric wire is inserted and guided into a conventional cylindrical front clamp. There is an advantage that the occurrence of this can be effectively prevented.

  Further, the fixed nozzle guide 68 and the movable nozzle guide 69, the exchange wire supply groove 59 of the front clamp 2 and the wire guide blocks 65a and 65b are opened upward, and the holding release posture of the pair of wire holding means 49 and 50 is released. Since the gap between them and the space between the fixed roller 51 and the movable roller 52 are open upward and the replacement wire 10 can be delivered from above by the replacement wire supply mechanism 87, After the gripping mechanism 14 is temporarily moved to the retracted position, each clamp portion 92 of the replacement wire supply mechanism 87 is moved to the replacement wire supply position D, and then the wire gripping mechanism 14 is moved to the replacement wire delivery position B. Compared with the method of performing the displacement operation, the clamp portions 92 of the replacement wire supply mechanism 87 are replaced while being moved directly to the replacement wire delivery position B. It may be operated to move the wire feeding position D, the advantage that transfer the work of the replacement wire 10 can be performed better easily and efficiently.

  Further, the shutter 60 for closing the exchange wire supply groove 59 of the front clamp 2 so as to be freely opened and closed is structured to be opened and closed in conjunction with the separation operation of the pair of wire holding means 49 and 50. There exists an advantage which can perform the delivery operation | work of the electric wire 10 more efficiently.

  The electric wire gripping mechanism 14 includes an electric wire nozzle portion 67 having a nozzle opening that can be opened and closed, through which the electric wire 10 is inserted, downstream of the front clamp 2 in the electric wire feeding direction P, and a pair of electric wire holding means 49 and 50. The wire diameter measuring mechanism 81 for measuring the outer diameter of the wire 10 fed along the wire feeding direction P is provided on the side, and the magnitude of the wire diameter measured by the wire diameter measuring mechanism 81 via the link mechanism 74 The link opening 74 is used to separate and approach the pair of wire holding means 49 and 50, and the shutter 60 is opened and closed using this link mechanism 74. In addition, since the nozzle opening is in the open posture in the holding release posture by the separation operation of the pair of electric wire holding means 49, 50, it can also be used as a component. Since the attained effectively, there is an advantage that the manufacturing cost can be reduced.

  Further, the link mechanism 74 is used to link the separating operation and approaching operation of the pair of electric wire holding means 49 and 50 with the opening operation and closing operation of the shutter 60, and the interlocking mechanism is simple and inexpensive. There are also advantages that can be provided.
