It includes a locking member 164 for fixing the wire 2 so that it is not transferred, and a return means for returning the locking member 164 to its original position.

At this time, the return means may be a spring or pneumatic force providing force to push the locking member 164 to its original position.

Meanwhile, a front wire selection unit 121 may be formed in front of the forward transfer unit 130, and a nozzle unit 124 guiding the wire 2 passing through the wire selection unit 121 may be provided.

At this time, a funnel-shaped guide 124a for guiding the wire 2 to the central hole of the nozzle unit 124 may be provided at the front end of the front wire selector 121 .

At this time, a transparent guide tube 124b for guiding the electric wire 2 may be provided between the front end of the nozzle part 124 and equipment receiving the electric wire 2 and proceeding with the next process.

Referring to Figure 1, a wiring harness equipment 1 according to an embodiment of the present invention is shown as a whole. The wire (2) selected in the wire changing device 100 is positioned at the processing height, and the wire (2) is supplied to the wire control unit 200 by the forward conveying unit 130, and the wire control unit 200 has the wire ( 2) is supplied to the cutting and peeling equipment 300 by adjusting the direction. Here, a portion of the front end of the wire 2 is stripped and the wire control unit 200 changes the direction and supplies it to the pressing equipment 400 and 400' on the side.

In the pressing equipments 400 and 400', terminals corresponding to the stripped parts of the wire 2 are physically coupled by a pressing process.

After that, the wire control unit 200 returns to the original position, and the wire 2 is moved forward by the wire transfer unit 130 . At this time, the transfer distance of the electric wire 2 follows the set value, and the cutting operation is performed. Then, the front end of the cut wire 2 goes through the above-described peeling and pressing processes. The front wire 2 is discharged after peeling and pressing processes are performed at the rear end of the wire by another wire control unit installed on the opposite side of the wire control unit 200.

When the wire 2 is replaced with another wire while performing this operation repeatedly, the wire being worked is transported backward by the backward transfer unit 150 . That is, the front end of the wire 2 being worked is located at the wire control unit 200, then moves backward to the position where it is stopped by the clamp unit 160 of the front transfer unit 130, and then the clamp unit 160, 170 position is fixed. Accordingly, the electric wire (2) that was working is stopped while slightly hanging behind the rear clamp (170).

Then, the elevating frame 120 moves up and down so that the selected wire is located at the processing height, the clamp units 160 and 170 holding the replacement wire are released, and the wire is supplied to the wire control unit 200 by the forward transfer unit 130. and work commences. In this way, the replacement of the wire is automatically performed, so that the machine can continue to work without stopping, thereby providing more production.

Referring to FIGS. 2 and 3 , parts for wire transfer are installed on the upper surface of the fixing frame 110 to form a processing height. At this processing height, the nozzle unit 124, the front clamp 160, the forward transfer unit 130, the straightening unit 140 that straightens the wire, the backward transfer unit 150, and the rear clamp 170 are sequentially installed from the front. has been The wire 2 selected at the processing height is fixed by the clamp units 160 and 170, and when the clamp units 160 and 170 are released, the wire transfer is started by the forward transfer unit 130. The electric wire 2 passes through the through hole 123a of the rear electric wire selection part 123 at the rear of the wire changing device 100, passes through the backward transport part 150 without interference, and then passes through the guide frame 122, After the electric wire is straightened in the straightening unit 140, it passes through the guide frame 122 again. Then, it continues to move forward by the forward conveying part 130, passes through the through hole 121a of the front wire selector 121, and then leaves the wire changing device 100 through the nozzle part 124. The wire 2 is transferred to the wire control unit 200 along the guide tube 124b connected to the nozzle unit 124, and processing is performed. As described above, in the replacement of the electric wire 2, the reverse transfer part 150 operates so that the front end of the electric wire 2 moves backward from the electric wire control part 200 to the position of the front clamp unit 160, and the clamp unit at that position. The wires 2 being worked on are fixed by the slabs 160 and 170. Then, the elevating frame 120 moves up and down to adjust the position so that the wire to be replaced is located at the processing height. At the processing height, the clamp units 160 and 170 of the wire 2 are released, and the same operation is repeated while the forward transfer unit 130 operates to supply a new replacement wire.

At this time, the wire 2 being worked on will hang down at the rear of the wire replacement device 100 because it has moved backward a certain distance. However, if the roll supplying the wire also rotates the same distance, it will be able to rewind and rewind the stretched wire to prevent it from being stretched.

Referring to FIG. 4 , the rear clamp unit 170 restrains the wire 2, and other parts show a state in which the wire is released. The electric wire 2 can be supported in a straight line while passing through the three guide frames 122, and finally leaves the replacement device 100 through the nozzle part 124 by the forward transfer part 130. .

Referring to FIGS. 5 and 6 , the configuration of the backward transfer unit 150 is shown. Referring to this, since the rollers 151 are each assembled to the base block 152, the rollers 151 are separated from each other by the electric wire 2 according to the operation of the driving cylinders 152a connected to the base block 152, respectively. It can be spaced apart or moved so that it is in close contact with the electric wire located therebetween. When the reverse driving roller 151 is driven and rotated by the driving motor 153 in a closely attached state, the wire 2 moves backward. The rollers 151 remain spaced apart from each other except for the backward operation.

Referring to FIG. 7 , a front wire selection unit 121, a clamp unit 160, and a nozzle unit 124 are shown. After the wire 2 passes through the front selector 121, it moves to the wire control unit 200 via the nozzle unit 124. At this time, the clamp unit 160 is installed on the side of the wire selector 121, and the wire 2 can be fixed to the front wire selector 121 by the operation of the pushing member 161 of the clamp unit 160. will be. At the time of replacing the wire, the front end of the wire 2 being worked on may be reversed from the wire control unit 200 to the wire selection unit 121 through the nozzle unit 124 and then fixed by the clamp unit 160. The new replacement wire is determined by the operation of the elevating frame 120, the front end of the wire 2 is released by the release of the clamp units 160 and 170, and the front end of the replacement wire is guided by the funnel-shaped guide by the forward transfer unit 130. After passing through the nozzle part 124 under the guidance of (124a), it will be transferred to the wire control unit 200 via the guide pipe (124b).

8 to 10, the structure of the clamp unit 160 is shown. A front clamp unit 160 is shown, and a rear clamp unit 170 also has the same structure. The clamp unit 160 is fixed to the base block 162 on which the pushing member 161 is operated forward and backward by the driving cylinder 163, and a shock relieving member 161a is installed at the front end. The pushing member 161 pushes the locking member 164 so that the through hole 164a of the locking member 164 coincides with the through hole 121a of the wire selector 121, so that the electric wire 2 is positioned there. It is released from the fixation and transport is possible. Conversely, when the locking member 164 is returned by the return means, the wire is fixed. The return means may use a spring or pneumatic pressure as described above. Here, it is designed to return using pneumatic pressure. The locking member 164 is inserted into the locking hole 121b of the wire selector 121, the front is supported by the support block 165, and when locked, the operating distance of the locking member 164 is limited. .

Since the replacement of the above-mentioned wires is usually performed semi-automatically or manually, when the work is performed while replacing various wires, the time to manually replace wires during working hours occupies a very large portion of the actual working time, but in the present invention, automatic Since the wires are quickly replaced, replacement and work can be performed quickly and continuously without stopping the wiring harness equipment 1, so productivity can be improved.

On the other hand, referring to FIGS. 11 to 14, a wire replacement device for wiring harness equipment according to another embodiment of the present invention is shown.

Here, the rollers for reversing the wire are made of a conductive material and a detection block is provided to electrically detect when the rollers are in close contact and an electrical signal is generated or the coating of the wire is exposed and is in close contact with the rollers. There is a difference from the previous embodiment.

That is, the backward driving roller and the backward driven roller may be made of a conductive material, connected to each of the backward driving roller and the driven roller with a detection block, and whether electricity is continuity may be detected through the detection block.

At this time, the detection block may detect a state in which the backward driving roller and the backward driven roller contact each other and a state in which a core wire of an electric wire is exposed between the backward driving roller and the backward driven roller. Therefore, even coating defects can be detected.

In this case, a base block made of an insulating material may be provided between the pair of driving cylinders, the backward driving roller, and the backward driven roller.

Referring to FIGS. 11 to 14 , the detection block is installed under the reverse driving roller and the reverse driven roller, respectively. Referring to FIG. 14 , a reverse drive roller and a reverse driven roller are in close contact with each other. At this time, electricity flows through the detection blocks, and by electrically detecting it, it is possible to detect that there is no electric wire between the reverse drive roller and the reverse driven roller. If there is a covered electric wire between the reverse driving roller and the backward driven roller, electricity does not flow to the detection blocks, so that the existence of the electric wire can be detected. Depending on this information, it is possible to control the operation of the reverse driving roller and the reverse driven roller.

In addition, the detection block can detect the case where the core wire, which is a so-called wire joint, is passing through, so that the core wire connection can be detected when trying to shorten the material supply time by removing the coating at the end of the wire and connecting the core wire. You can make this work possible.

Of course, since electricity flows through the reverse rollers and the detection block, a base block physically supporting them may be made of an insulating material such as acetal.
