Here, of the pair of transfer gripping parts 74Ap and 74Aq, the transfer gripping part 74Ap on the other transfer gripping part 70B side is a fixed side, and the transfer gripping part 74Aq on the opposite side is transferred. The gripping portion 74Ap is driven to approach and separate.

  The transfer gripping portion 70B on the other side is provided on the base plate 71B side, and similarly to the transfer gripping portion 70A, a transfer lifting drive unit 72B corresponding to the transfer lifting drive unit 72A, And an opening / closing drive part 73B corresponding to the opening / closing drive part 73A and a pair of transfer gripping parts 74Bp, 74Bq corresponding to the pair of transfer gripping parts 74Ap, 74Aq.

  This transfer gripping portion 70B is different from the transfer gripping portion 70A in that the lower end portion of the elevating movable portion 72Bb provided in the elevating drive main body 72Ba is directed toward the one side transfer gripping portion 70B. The open / close drive unit 73B is supported in a suspended manner at a position from the transfer gripping part 70B on one side of the lower end part of the up-and-down movable part 72Bb.

  Further, the pair of transfer gripping portions 74Ap and 74Aq are bent in a substantially L shape so that the tip end portions thereof are disposed at positions closer to the transfer gripping portion 70B on the other side. The loading gripping portions 74Bp and 74Bq are bent in a substantially L shape opposite to the above so that the tip end portions thereof are disposed at positions closer to the transfer gripping portion 70A on one side. Then, with the two transfer gripping portions 70A and 70B being brought close to each other, the tip portions of the pair of transfer gripping portions 74Ap and 74Aq and the tip portions of the pair of transfer gripping portions 74Bp and 74Bq are compared. Thus, the both ends of the terminal-attached electric wire WT can be gripped and released at relatively close positions.

  The transfer operation of the terminal-attached electric wire WT by the terminal-attached electric wire transfer mechanism 60 is performed as follows.

  That is, by driving the wire end moving drive unit 88b, the pair of wire end holding units 88a holding both ends of the terminal-attached electric wire WT is moved to the wire delivery position WP. In this state, the pair of transfer gripping portions 70A and 70B are arranged on the electric wire delivery position WP by driving the transfer gripping portion moving drive unit 62. Thereafter, the pair of transfer gripping portions 74Ap and 74Aq and the pair of transfer gripping portions 74Bp and 74Bq are opened, and the pair of transfer gripping portions 74Ap is driven by the transfer lifting and lowering drive portions 72A and 72B. , 74Aq and the pair of transfer gripping portions 74Bp, 74Bq. Thereafter, when the pair of transfer gripping portions 74Ap and 74Aq and the pair of transfer gripping portions 74Bp and 74Bq are closed by driving the opening / closing drive portions 73A and 73B, the terminals gripped by the pair of wire end holding portions 88a. Both ends of the attached electric wire WT are respectively gripped by a pair of transfer gripping portions 74Ap and 74Aq and a pair of transfer gripping portions 74Bp and 74Bq. Thereafter, in a state in which the gripping by the pair of electric wire end holding portions 88a is released, the pair of transfer gripping portions 74Ap and 74Aq and the pair of transfer gripping portions 74Bp are driven by driving the transfer lifting and lowering drive portions 72A and 72B. , 74Bq. After the ascent, the pair of transfer gripping portions 70A and 70B is driven by the transfer gripping portion moving drive unit 62, and the electric wire holding bar 10 is supported at a predetermined position on the side of the electric wire holding bar transport device 20, and includes a plurality of The wire holding part 12 is moved to any upper position. When the pair of transfer gripping portions 74Ap and 74Aq and the pair of transfer gripping portions 74Bp and 74Bq are lowered by driving the transfer lifting / lowering drive portions 72A and 72B, the ends of the terminal-attached electric wires WT hold the electric wires. It is clamped between a pair of elastic clamping pieces 13 of the part 12. After that, the pair of transfer gripping parts 74Ap and 74Aq and the pair of transfer gripping parts 74Bp and 74Bq are opened by driving the opening / closing drive parts 73A and 73B, and further, by driving the transfer lifting and lowering drive parts 72A and 72B. When the pair of transfer gripping portions 74Ap and 74Aq and the pair of transfer gripping portions 74Bp and 74Bq are raised, one operation of transferring both ends of the terminal-attached electric wire WT is completed. By changing the wire holding part 12 as a transfer destination and repeating the above, both ends of the plurality of terminal-attached electric wires WT are sequentially transferred to the wire holding bar 10. In addition, by changing the type of the terminal-attached electric wire WT at the transfer source electric wire delivery position WP, both end portions of different types of the terminal-attached electric wires WT can be transferred to the electric wire holding bar 10. Different types of terminal-attached electric wires WT may be performed in a state where the electric wire holding bar 10 is disposed at a fixed position, or, as will be described later, the electric wire holding bar 10 is circulated by the electric wire holding bar conveying device 20. You may go after.

  But the structure which transfers the electric wire WT with a terminal is not restricted to the said example. The both ends of the terminal-attached electric wire WT may be transferred to the electric wire holding bar 10 by sequentially transferring the both ends of the electric wire with terminal WT, and the end portions of the electric wire WT with terminal are transferred one by one. You may make it do.

  The operation control of the terminal-attached electric wire transfer mechanism 60 is performed by a transport control unit 20U configured by a general microcomputer including a CPU, a ROM, a RAM, and the like. In particular, when a signal indicating that the terminal-attached electric wire WT has been transferred to the delivery position WP is input from the terminal crimping control unit 80U, the transfer control unit 20U transfers the terminal-attached electric wire WT at that timing. The operation control of the terminal-attached electric wire transfer mechanism 60 is performed.

<Wire holding bar transport device>
The electric wire holding bar conveyance device 20 will be described. FIG. 10 is a schematic plan view showing the curved path P1 portion of the electric wire holding bar conveyance device 20, and FIG. 11 is a schematic side view showing the curved path P1 portion of the electric wire holding bar conveyance device 20.

  As shown in FIGS. 1, 2, 10, and 11, the electric wire holding bar transport device 20 includes a plurality of bar support portions 22 and a circulation rotation drive mechanism portion 30.

  The circulation rotation drive mechanism section 30 includes a pair of pulley bodies 32, a circulation rotation drive belt 34 wound around the pair of pulley bodies 32, and a circulation rotation drive section 36.

  The pair of pulley bodies 32 are rotatably supported on the support column 21 via brackets at positions separated by a predetermined distance. Each pulley body 32 is rotatable in a substantially horizontal posture at a predetermined height position. The circulation rotation drive mechanism unit 30 is configured by a rotation drive unit capable of adjusting the amount of rotation, such as a servo motor, and the rotation drive shaft is coupled to the rotation shaft of one pulley body 32. The rotation drive shaft of the circulation rotation drive mechanism unit 30 and the rotation shaft of one pulley body 32 need only be connected in a manner capable of transmitting the rotation drive force, and are connected via a transmission belt, gears, and the like. Also good.

  A circulation rotation drive belt 34 is wound around the pair of pulley bodies 32. The circulation rotation drive belt 34 circulates and rotates along a substantially oval circulation path P by the rotation drive of the circulation rotation drive mechanism 30.

  The plurality of bar support portions 22 are fixed to the circulation rotation drive belt 34 at substantially equal intervals. Each bar support portion 22 is fixed to the outward surface of the circulation rotation drive belt 34 and is configured to be able to support the electric wire holding bar 10 in a posture extending outward from the circulation path P. .

  More specifically, the bar support portion 22 is formed in a substantially bar-shaped member that is shorter than the wire holding bar 10 and larger than the width of the wire holding bar 10. One end portion of the bar support portion 22 is fixed to the outward surface of the circulation rotation drive belt 34 and is configured to extend outward from the outward surface of the circulation rotation drive belt 34. The bar support portion 22 is formed with a holding groove 22g in which the electric wire holding bar 10 can be disposed along the longitudinal direction thereof. The holding groove 22g has a groove shape that opens upward, is closed on the base end side of the bar support portion 22, and is open on the distal end side of the bar support portion 22. Then, the wire holding bar 10 is brought into contact with the proximal end side of the holding groove 22g, and the other end of the wire holding bar 10 is extended from the opening on the distal end side of the holding groove 22g. The bar 10 is held in the holding groove 22g. Further, a retaining pin 22p is provided in a projecting manner above the base end portion of the holding groove 22g. When the wire holding bar 10 is disposed in the holding groove 22g, the retaining pin 22p is connected to the electric wire. It fits into the locking recess 18 h of the holding bar 10. This prevents the wire holding bar 10 from dropping from the holding groove 22g to the tip side. In addition, after fitting the electric wire holding bar 10 into the holding groove 22g in an oblique posture, the electric wire holding bar 10 is disposed in the holding groove 22g in a substantially horizontal posture, so that the retaining pin 22p is engaged with the locking recess 18h. Can be fitted.

  The plurality of bar support portions 22 are configured to be circulated and rotated along the curved path P1 in the circulation path by the rotation drive of the circulation rotation drive mechanism 30.

  In the electric wire holding bar transport device 20, the terminal-attached electric wire WT is transferred in one curved path P1 portion of the circulation path, and the electric wire holding bar 10 is replenished and taken out in one linear path P2.

  That is, when the electric wire holding bar 10 is conveyed to the curved path P1 portion along the outer periphery of the pulley body 32 on one side (here, the right side), the electric wire holding bar 10 is substantially orthogonal to the tangent line of the curved path P1 portion. It becomes the attitude | position extended along the direction (radial direction) to do. For this reason, in the curved path P1 part, the plurality of electric wire holding bars 10 extend so as to expand radially, and a gap is formed between the adjacent electric wire holding bars 10 so that the interval increases sequentially toward the outside. Therefore, in this portion, the terminal-attached electric wire transfer mechanism 60 and the terminal-attached electric wire WT itself to be transferred are unlikely to interfere with the adjacent electric wire holding bar 10 or the like. Therefore, the curved path P1 is suitable for transferring the terminal-attached electric wire WT to the electric wire holding bar 10.

  Here, for the wire holding bar 10 conveyed to the curved path P1 portion, the one conveyed to a position along the linear direction connecting the pair of pulley bodies 32 (hereinafter referred to as transfer receiving position WQ), The terminal-attached electric wire WT is transferred. That is, the plurality of electric wire holding bars 10 are conveyed along the circulation path P, and every time the electric wire holding bar 10 reaches the transfer receiving position WQ, the conveyance of the electric wire holding bars 10 is stopped and the electric wire WT with terminal is moved. To do. Then, when the transfer of the predetermined terminal-attached electric wire WT is completed, the plurality of electric wire holding bars 10 are circulated and conveyed again, and the next electric wire holding bar 10 is disposed at the transfer receiving position, so that the terminal-attached electric wires WT are transferred. Transfer. By repeating this, the terminal-attached electric wires WT are sequentially transferred to the plurality of electric wire holding bars 10.

  In addition, the position which transfers with respect to the electric wire holding bar 10 is not restricted to the said example, What is necessary is just to be performed in the curved path | route part which protrudes outside.

  Further, between the wire holding bar 10 located at the transfer receiving position WQ and the wire holding bar 10 located on the downstream side in the carrying direction with respect to the wire holding bar 10, the wire holding bar 10 is moved and moved. An interference regulation bar 23 is provided at a position above the locus. The interference regulating bar 23 is formed in an approximately U-shaped member having a portion extending in a substantially horizontal direction along the gap between the wire holding bars 10 and a portion extending upward from both ends thereof. It is fixedly supported by the holding bar transport device 20 or other supporting portions. When the terminal-attached electric wire WT is transferred to the electric wire holding bar 10 located at the transfer receiving position WQ, the terminal-attached electric wire WT is prevented from interfering with the electric wire holding bar 10 on the downstream side in the transport direction. And has a role of regulating the movement of the terminal-attached electric wire WT.

  Moreover, the bar free end holding part 24 which can hold | maintain the said free end part temporarily is provided in the position corresponding to the free end part of the electric wire holding bar 10 located in the said transfer receiving position WQ.

  FIG. 12 is a side view showing the bar free end holding portion 24, and FIG. 13 is a rear view showing the bar free end holding portion 24.

  The bar free end holding part 24 has a sandwiching holding part 25, a bottom receiving part 26, and an end face receiving part 27.

  The clamping holding part 25 is arrange | positioned under the free end part of the electric wire holding bar 10 located in the transfer receiving position WQ with a bracket. The sandwiching holding unit 25 includes a pair of sandwiching pieces 25a and a sandwiching opening / closing drive unit 25b that opens and closes the sandwiching pieces 25a. The sandwiching opening / closing drive unit 25b includes an actuator such as an air cylinder and a link member that opens and closes the sandwiching piece 25a. The pair of sandwiching pieces 25a is formed in a scale member having a substantially L-shaped cutout portion on the inner side of the distal end portion, and the base end portion thereof opens and closes to the sandwiching opening / closing drive portion 25b via a predetermined shaft portion. It is supported so that it can be driven. When the pair of sandwiching pieces 25a is opened, the electric wire holding bar 10 conveyed along the circulation path P does not interfere with the pair of sandwiching pieces 25a and is disposed at a position above the sandwiching opening / closing drive unit 25b. It is possible to move from the upper position to the side. Further, when the pair of sandwiching pieces 25a is closed in a state where the wire holding bar 10 is disposed at the upper position of the sandwiching opening / closing drive unit 25b, the free end of the wire holding bar 10 is interposed between the distal ends of the sandwiching pieces 25a. Part is to be sandwiched.

  Further, the bottom receiving portion 26 is disposed below the free end portion of the electric wire holding bar 10 located at the transfer receiving position WQ. Here, the bottom receiving portion 26 is fixed to the sandwiching opening / closing drive portion 25b so as to correspond to the position. It is arranged. The bottom receiving portion 26 is capable of contacting the bottom surface of the free end portion of the electric wire holding bar 10 positioned at the transfer receiving position WQ, and is inclined downward from the bottom receiving main surface 26a toward the outside. And a bottom support auxiliary guide surface 26b.

  The end surface receiving portion 27 is disposed on the outward extension of the free end portion of the wire holding bar 10 located at the transfer receiving position WQ. The end surface receiving portion 27 includes an end surface abutting portion 27b and an end surface abutting drive portion 27a that drives the end surface abutting portion 27b to advance and retreat. The end surface abutting drive unit 27a is configured by a linear actuator such as an air cylinder, and is fixed via a bracket or the like. The end surface abutting portion 27b has a flat surface that can abut on the end surface of the free end portion of the electric wire holding bar 10, and is supported so as to be able to advance and retreat relative to the end surface of the free end portion of the end surface abutting drive portion 27a. Has been. And in the state which retracted the end surface contact part 27b, the end surface of the free end part of the electric wire holding bar 10 located in the transfer receiving position WQ and the end surface contact part 27b are in a non-contact state, and the end surface contact part 27b. In the state in which is advanced, the end surface of the free end portion of the electric wire holding bar 10 located at the transfer receiving position WQ and the end surface abutting portion 27b are in a contact state.

  When the electric wire holding bar 10 moves along the circulation path P to the transfer receiving position WQ, the bottom portion of the free end portion of the electric wire holding bar 10 is guided while being in sliding contact with the one side bottom receiving auxiliary guide surface 26b. It is placed on the bottom receiving surface 26a. Moreover, when a pair of clamping piece 25a is closed in this state, the free end part of the electric wire holding bar 10 will be clamped between the front-end | tip parts of the clamping piece 25a. Further, when the end surface abutting portion 27 b is advanced, the end surface abutting portion 27 b comes into contact with the end surface of the free end portion of the wire holding bar 10.

  Thereby, the free end part of the electric wire holding bar 10 comes to be more reliably positioned in the width direction, the downward direction, and the outward direction of the end part. Therefore, when the terminal-attached electric wire WT is transferred to the electric wire holding bar 10, it is possible to suppress the shaking of the electric wire holding bar 10 and to transfer more reliably.

  The bar free end holding part 24 only needs to position the free end of the wire holding bar 10 in at least one direction. For example, the pin holding part 25, the bottom receiving part 26, and the end face receiving part 27 The structure which employ | adopted at least one of them may be sufficient. However, from the viewpoint of preventing the wire holding bar 10 from shaking when the terminal-attached electric wire WT is transferred, it is preferable to perform the positioning toward the bottom side.

  The operation control of the electric wire holding bar conveyance device 20 is performed by the conveyance control unit 20U. In particular, in cooperation with the terminal crimping control unit 80U and the like, a predetermined number or type of terminal-attached electric wires WT are transferred to each electric wire holding bar 10, and a plurality of electric wire holding bars 10 are provided. In the case of carrying out batch loading / unloading, the conveyance timing of the electric wire holding bar 10 is controlled so as to be stopped for a time required for the work.

<Operation>
Operation | movement of the said electric wire holding bar conveyance apparatus 20 is demonstrated including the usage method.

  First, in the initial state, it is assumed that the wire holding bar 10 is supported by each bar support portion 22. In this state, the electric wire holding bar 10 is conveyed along the circulation path P by driving the circulation rotation drive mechanism 30. Then, when any one of the wire holding bars 10 is disposed at the transfer receiving position WQ, the conveyance is temporarily stopped. In this state, one or more of the terminal-attached electric wires WT manufactured by the terminal crimping device 80 are transferred to the electric wire holding bar 10 at the transfer receiving position WQ by the terminal-attached electric wire transfer mechanism 60. Then, when a predetermined number and type of terminal-attached electric wires WT are transferred to the electric wire holding bar 10, each electric wire holding bar 10 is arranged so that the next electric wire holding bar 10 is arranged at the transfer receiving position WQ. The bar 10 is conveyed. Then, the terminal-attached electric wire WT is transferred to the next electric wire holding bar 10 in the same manner as described above.

  It should be noted that the transfer of the terminal-attached electric wire WT to the electric wire holding bar 10 may be completed by stopping once at the transfer receiving position WQ, or may be stopped a plurality of times at the transfer receiving position WQ by making a plurality of turns. Thus, the transfer may be performed a plurality of times. In the latter case, a different type of terminal-attached electric wire WT may be transferred each time the transfer receiving position WQ is stopped a plurality of times.

  When the transfer of the terminal-attached electric wires WT to the predetermined number of the electric wire holding bars 10 is completed and the transferred electric wire holding bars 10 are conveyed to the linear path P2 portion, the electric wire holding bars 10 of the linear path P2 are transferred. Removal is performed.

  In this case, the plurality of electric wire holding bars 10 can be taken out in a state where a plurality of the electric wire holding bars 10 that have been transferred are arranged in parallel in the straight path P2.

  In addition, when the electric wire holding bar 10 is replenished, the plural electric wire holding bars 10 are collectively arranged in a state where a plurality of empty bar support portions 22 are arranged adjacent to the outside of the straight path P2 portion. It can be supported by the support portion 22.

  As described above, it is possible to obtain a terminal-attached electric wire WT in which at least one type of terminal-attached electric wire WT is set, preferably a plurality of types.

  According to the electric wire holding bar transport device 20 configured as described above, the bar holding portion 22 is circulated and rotated in a state where the electric wire holding bar 10 is supported by each of the plurality of bar supporting portions 22, thereby circulating. The plurality of electric wire holding bars 10 can be sequentially conveyed to the transfer receiving position WQ in the middle of the path P. In addition, the electric wire holding bar 10 passing through the curved path P1 is disposed so as to radially expand outward, and a relatively wide gap is formed between the adjacent electric wire holding bars 10. For this reason, a mechanism for transferring the terminal-attached electric wire WT can be easily incorporated, and when the terminal-attached electric wire WT is transferred, the terminal-attached electric wire WT interferes with the adjacent electric wire holding bar 10 or the like. hard. For this reason, the electric wire WT with a terminal can be transferred easily.

  Moreover, since the circulation path | route P has the linear path | route P2, the several electric wire holding | maintenance bar 10 currently passing through the said linear path | route P2 part is located in a line in parallel. For this reason, it is easy to put in and take out the plurality of electric wire holding bars 10 at the same time, and it is possible to carry out efficiently and quickly. But the straight path P2 is not essential, for example, the movement path | route of the electric wire holding | maintenance part 22 may be made into substantially circular shape.

  The wire holding bar transport device 20 is also suitable for manufacturing a wire set in which a plurality of types of terminal-attached wires WT are set on the wire holding bar 10 in order to manufacture a sub-assembly and the like.

  That is, each time the wire holding bar 10 circulates along the circulation path P and passes through the curved path P1, a different type of terminal-attached electric wire WT is transferred to the wire holding bar 10. Transfer of different types of terminal-attached electric wires WT can be realized by using different types of terminal-attached electric wires that can be manufactured as terminal crimping devices, or by exchanging terminal-crimped electric wires. Thereby, the electric wire set (refer FIG. 1) which mixed and hold | maintained the electric wire WT with a different kind in the electric wire holding bar 10 can be manufactured.

  Thereby, an electric wire set can be manufactured with comparatively simple equipment.

  In particular, in a configuration that can supply different types of electric wires with terminals by exchanging terminal crimping electric wires, the following merits are achieved.

  That is, when an electric wire set or a sub-assembly is to be manufactured using a terminal crimping apparatus capable of crimping a single type of terminal, the electric wires WT with terminals are usually manufactured for each type and summarized for each type. A predetermined type of terminal-attached electric wire is taken out from the inside, and an electric wire set or a sub-assembly is manufactured. However, in this case, the manufacturing operation is very troublesome.

  In order to avoid this, a terminal crimping device capable of crimping a plurality of types of terminals may be used, and a plurality of types of terminals-attached wires necessary for the wire set or sub-assembly may be mixed and manufactured. However, a terminal crimping apparatus capable of crimping a plurality of types of terminals requires replacement of a crimping die for each terminal, resulting in an expensive and complicated apparatus configuration.

  However, as described above, different types of electric wires with terminals are supplied by exchanging the terminal crimping electric wires, the electric wire holding bar 10 is rotated a plurality of times, and different types of electric wires with terminals WT are transferred for each rotation. By doing so, it is possible to manufacture the electric wire set by directly transferring the manufactured terminal-attached electric wire WT to the electric wire holding bar 10 while using a terminal crimping device having a relatively simple configuration. Thereby, an electric wire set can be manufactured with comparatively simple equipment, and the manufacturing process of a subassembly will be simplified.

<Modification>
Hereinafter, various modifications will be described based on the above embodiment.

  14 and 15 are diagrams showing a first modification. In the first modified example, the partition member is disposed between the electric wire holding bar 10 arranged at the transfer receiving position WQ and the adjacent electric wire holding bar 10 so as to be able to advance and retreat.

  That is, the partition mechanism part 110 is provided between the wire holding bar 10 disposed at the transfer receiving position WQ and the wire holding bar 10 adjacent on the downstream side in the transport direction.

  The partition mechanism unit 110 includes a partition member 112 and a partition drive unit 114.

  The partition drive unit 114 includes an air cylinder or the like, and includes a partition drive main body 114a and a rod portion 114b that can be driven forward and backward from the partition drive main body 114a. The partition drive main body 114a is disposed between the two electric wire holding bars 10 and above the electric wire holding bar 10, and is fixed to a predetermined bracket in a posture in which the rod portion 114b protrudes downward. Has been.

  The partition member 112 is a substantially rectangular member having substantially the same length as the wire holding bar 10, and extends along the gap between the two wire holding bars 10. The partition member 112 is connected to the tip portion of the rod portion 114b.

  When the rod portion 114b is driven to advance, the rod portion 114b is interposed between the two wire holding bars 10 so as to partition the wire holding portions 12 that hold the end portions of the terminal-attached electric wires WT (FIG. 15). 2). Further, in a state where the rod portion 114b is driven to retract, the rod portion 114b moves to a position above the movement restriction of the wire holding bar 10 and retracts from the interposition position (see the solid line in FIG. 15).

  When the terminal-attached electric wire WT is transferred to the electric wire holding bar 10 at the transfer receiving position WQ, the partition member 112 is disposed at the intervening position by driving the partition driving unit 114. Thereby, it is suppressed that the electric wire WT with a terminal to be transferred interferes with the adjacent electric wire holding bar 10 and the electric wire WT with a terminal held by the electric wire holding bar 10 or gets on the electric wire holding bar 10. Is done. In particular, since the partition member 112 is interposed between the electric wire holding bars 10, the interference of the terminal-attached electric wires WT can be more reliably suppressed than the interference regulation bar 23.

  Further, when the electric wire holding bar 10 is conveyed, the partition member 112 is retracted upward from the interposition position by driving the partition driving unit 114. Thereby, the electric wire holding bar 10 can be conveyed and moved without causing interference with the partition member 112.

  16 and 17 are diagrams showing a second modification. In the second modification, an example will be described in which a plurality of wire holding bars 10 in the straight path P2 portion can be easily taken out collectively.

  That is, in the above-described embodiment, since the retaining pins 22p are individually fitted into the electric wire holding bars 10 in the respective bar support portions 22, it is difficult to take out the electric wire holding bars 10 at once. The present modification relates to a configuration for releasing such retaining in a batch.

  In other words, each of the bar support portions 222 corresponding to the bar support portions 22 is provided with a retaining pin 230. The retaining pin 230 includes a rod-shaped pin main body portion 231 and a collar portion 232 provided at the base end portion of the pin main body portion 231. The distal end side of the pin main body portion 231 is formed with a diameter smaller than that of the proximal end portion, and a step portion is formed in the middle portion thereof.

  Further, the upper part of the base end portion of the bar support portion 222 has two ceiling walls with a gap in the vertical direction, and an insertion hole 222a into which the distal end side small diameter portion can be inserted is formed in the lower ceiling wall. In addition, an insertion hole 222b is formed in the upper ceiling wall so that the base end side large diameter portion can be inserted.

  The retaining pin 230 is inserted into the insertion holes 222b and 222a from above, and is inserted and supported so as to be movable forward and backward. In a state where the retaining pin 230 is located at the lowermost position (preventing position), the stepped portion of the pin main body portion 231 contacts the upper opening edge of the lower insertion hole 222a and the tip end portion of the pin main body portion 231 is It protrudes into the holding groove 222g (corresponding to the holding groove 22g) in the bar support portion 222. As a result, the electric wire holding bar 10 is fitted into the locking recess 18h of the electric wire holding bar 10 disposed in the holding groove 222g, and the electric wire holding bar 10 is held out. In this state, the collar portion 232 is located above the upper surface of the upper ceiling wall, and therefore a gap is formed between the collar portion 232 and the upper ceiling wall. The retaining pin 230 is applied with a downward force by its own weight or by a coil spring or the like, and is therefore normally positioned at the retaining position.

  When the retaining pin 230 is lifted from the retaining position to the upper retaining release position, the tip end portion of the pin main body 231 moves upward from the holding groove 222g and the fitting into the retaining recess 18h is released. Is done. Thereby, holding | maintenance of the said electric wire holding bar 10 is cancelled | released, and it can be taken out so that the electric wire holding bar 10 may be pulled out along a horizontal direction.

  Further, in the portion of the linear path P2 portion of the circulation path P that is the take-out work position, the retaining pins 230 of the plurality of bar support portions 222 that pass through the linear portion are collectively moved to the retaining release position. A pin batch driver 240 is provided.

  The pin batch drive unit 240 includes a push-up piece 242 and a push-up piece drive unit 244.
