[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring machine, and more particularly to a wiring machine which forms a conductor circuit having a predetermined shape by holding a wire between a plurality of wire press-fitting ribs arranged on a wire routing member. It is about the improvement of the machine.

[0002]

2. Description of the Related Art As shown in FIG. 12, a wire arranging member 1 has a plurality of wire press-fitting ribs 3 projecting at appropriate intervals along a wire laying path on a support base 2 having a desired shape. Are formed integrally with an insulating resin or the like. The wire press-fit rib 3 has a configuration in which a straight wire holding groove 3a capable of pushing a wire is formed by a pair of opposed walls 3b.

As shown in FIG. 13, such an electric wire routing member 1 clamps the electric wire 5 in the electric wire holding groove 3a of each electric wire press-fitting rib 3 according to the arrangement order along the wiring route of the electric wire. Thereby, the conductor circuit 6 passing through the plurality of wire press-in ribs 3 in order is formed. The conductor circuit 6 formed as described above may be, for example, a conductor circuit for supplying power to a light bulb in a vehicle combination lamp, or a vehicle circuit, as disclosed in Japanese Patent Application Laid-Open No. 6-275117. Is used as a conductor circuit for connecting to a bus bar or the like in the electric junction box.

[0004] By the way, automation for saving power of vehicle parts has been actively performed, and the work of laying the electric wire 5 on the electric wire laying member 1 has also been automated using a wiring machine as shown in FIG. It is planned. As shown in FIG. 14 (a), the wiring machine shown here is attached to a head moving means (not shown) and is capable of moving in an arbitrary direction on the electric wire routing member 1.
A wire nozzle 7a provided at the lower end of the wire feeding means and delivering the wire 5; and a wire nozzle 7a disposed downstream of the wire nozzle 7a in the traveling direction and holding the delivered wire 5 in the wire holding groove 3a.
And a press-fitting blade 7b that can move up and down to press-fit the inside. Then, after the electric wire 5 is put on the electric wire holding groove 3a by the moving operation of the wiring head 7, FIG.
As shown in (b), by pushing the electric wire 5 into the electric wire holding groove 3a with the press-fitting blade 7b, the electric wire 5 is held in the electric wire holding groove 3a.

[0005]

As shown in FIG. 15, when the installation directions of the wire press-fitting ribs 3 adjacent to the support base 2 in the order of wiring differ from each other, if the installation directions of the wire press-fitting ribs 3 are different, the wiring upstream The wire outlet 3c of the wire holding groove 3a of the wire press-in rib 3 is located at the wire holding groove 3 of the wire press-in rib 3 downstream of the wiring route.
a deviates from the extending direction L.

[0006] Between the wire press-fitting ribs 3 having different installation directions, the wiring machine as described above is used to press-fit the wire-pressing rib 3 on the upstream side from the outlet 3c of the wire holding groove 3a on the downstream side. When the electric wire 5 is guided to the outlet of the electric wire holding groove 3a of the rib 3, there is a possibility that the electric wire 5 crosses the upper end surface of the one opposing wall 3b obliquely as shown in FIG.

If the electric wire 5 does not cross the upper end surface of the one opposing wall 3b obliquely and does not fit well into the electric wire holding groove 3a, it is difficult to press the electric wire 5 by the press-fitting blade 7b. Or an accident such as breakage of the electric wire 5 may be caused, which has been a great obstacle to automation of electric wire routing. Therefore, an object of the present invention is to solve the above-described problems, and a conductor circuit having a predetermined shape is formed by holding a wire in a wire holding groove of a plurality of wire press-fitting ribs arranged on a wire routing member. An object of the present invention is to provide a favorable wiring machine which can facilitate automation of a wiring operation formed on a wiring member.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wire holding groove for a plurality of wire press-fitting ribs provided on a wire arranging member. A wiring machine attached to a head moving means, wherein the wiring head is provided at a lower end of the wire feeding means and feeds the wire. A sending portion, a press-fitting blade arranged on the downstream side in the traveling direction of the wire sending-out portion and capable of moving up and down to press the sent-out wire into the wire holding groove, and holding the press-fitting blade from both sides. And a wire guide portion formed with a guide groove through which the wire sent from the wire sending portion can be inserted, and the press-fitting blade advances to pinch the wire. When the wire is pushed into the groove, the wire Thus it is achieved by the wiring machine, characterized in that guided in the extending direction of the wire holding grooves.

According to the above configuration, when the wiring head sequentially moves between the wire press-fitting ribs, the wire sent from the wire sending portion is inserted into the guide groove of the wire guide portion,
The sending direction of the electric wire is restricted at least at a portion inserted into the guide groove. Therefore, when the wiring head is guided on the wire press-fitting rib of the next press-fitting object, the guide groove of the wire guide portion that determines the sending direction of the wire is inserted into the wire of the wire press-fitting rib of the press-fitting object. The wiring head is moved so as to match the extending direction of the holding groove.

[0010] When the direction of the guide groove of the wire guide portion matches the extending direction of the wire holding groove of the wire press-fitting rib,
The wiring head is lowered as it is, so that the guide groove is substantially communicated with the wire holding groove. In this state, even when the wire outlet of the wire holding groove of the wire press-fitting rib located on the upstream side of the wire press-fitting rib of the press-fitting object is displaced from the extending direction of the wire holding groove of the wire-pressing rib of the press-fitting object, The wire at the portion pushed into the press-fitting blade is straightened by the guide groove of the wire guide portion into a straight line along the wire holding groove, and is supported accurately along the wire holding groove. Then, in this state, if the press-fitting blade is advanced and the electric wire along the wire holding groove is pushed into the wire holding groove, the press-fitting can be performed reliably.

Therefore, since the electric wire guided by the wiring head does not cross the upper edge of the opposing wall which forms the wire holding groove of the wire press-fitting rib to be press-fitted, the work of pressing the wire into each wire press-fitting rib is not performed. Can be reliably performed, and it is possible to easily automate the wiring work by the wiring machine that forms the conductor circuit of the predetermined shape on the wire wiring member.

Preferably, the head moving means changes the moving direction by turning the wiring head around a downstream end of the guide groove in the electric wire guide portion as a center of rotation. In this case, after the wiring head has completed the press-fitting of the wire into the wire press-fitting rib, the wiring head is moved until the downstream end of the guide groove in the wire guide section passes through the wire holding groove of the wire press-fitting rib. Then turn to change the moving direction of the wiring head. Thereby, even if the wiring head is swung largely toward the wire press-fit rib on the downstream side, the wire guide portion does not apply excessive tension to the wire inserted in the guide groove, and the upstream side There is no danger that the wires pressed into the wire pressing ribs may fall off or the wires inserted into the guide grooves may come off.

Further, after the wiring head is guided on the wire press-fitting rib to be pressed next, the guide groove of the wire guide portion is aligned with the extending direction of the wire holding groove of the wire press-fitting rib to be press-fitted. When the wiring head is largely turned, the wiring head is moved and then turned until the downstream end of the guide groove in the wire guide coincides with the extending direction of the wire holding groove. Thereby, even if the wiring head is largely turned until it coincides with the extending direction of the wire holding groove, the wire guide portion does not apply excessive tension to the wire inserted into the guide groove, The electric wire inserted into the guide groove does not come off and is no longer supported along the electric wire holding groove.

The wiring machine 11 of the present embodiment is similar to that of FIGS.
As shown in FIG. 12, a wiring head 17 attached to a head moving means (not shown) and movable in a three-dimensional direction allows a plurality of wire press-fitting ribs 3 on a wire routing member 1 as shown in FIG. A predetermined conductor circuit 6 is formed by holding the electric wires 5 in order. The wiring head 17 is provided at a lower end of the electric wire feeding means 21 and is an electric wire nozzle 13 which is an electric wire sending unit that sends out the electric wire 5,
A press-fitting blade 15 which is arranged on the downstream side (the right side in FIG. 1) in the traveling direction of the wire nozzle 13 and which can move up and down so as to press-in the sent wire 5 into the wire pinching groove 3a of the wire press-fitting rib 3;
An electric wire guide portion 25 extending in the press-fitting blade reciprocating direction so as to sandwich the press-fitting blade 15 from both sides, and formed with a guide groove 27 through which the electric wire 5 sent from the electric wire nozzle 13 can be inserted; An electric wire cutter 23 is provided for cutting the electric wire 5 sent from the electric wire nozzle 13 at a predetermined length.

As the head moving means, a known three-axis moving mechanism capable of moving the wiring head 17 by an arbitrary amount in the X-axis, Y-axis, and Z-axis directions orthogonal to each other can be used. is there. The head moving means can also turn the wiring head 17 around the axis 19 passing near the downstream end of the guide groove 27 in the electric wire guide 25. Here, the distance between the axis 19 and the downstream end of the guide groove 27 is such that when the wiring head 17 is turned near the press-fitted wire press-fitting rib 3, the wire 5 is not bent. What is necessary is just to set it to the minimum necessary so that it does not occur.

The electric wire supply means 21 supplies the electric wire 5 supplied from a drum (not shown) and guided to the electric wire feeding cylinder 29.
A driving roller 31 and a nip roller 32 for holding the nip are provided. The drive roller 31 is driven to rotate by an electric motor 35 via a gear mechanism 34. In addition, the nip roller 32 can adjust an interval between the nip roller 32 and the drive roller 31 via an air cylinder 36 and a link 37.

The electric wire supply means 21 can send out the electric wire 5 at an arbitrary speed by controlling the electric motor 35 to rotate. Also, by widening the holding interval between the driving roller 31 and the nip roller 32 to a predetermined value or more, the holding of the electric wire 5 can be released, and the electric wire 5 can be pulled out by tension or the like acting on the electric wire 5 sent out from the electric wire nozzle 13. it can.

As shown in FIGS. 3 and 4, the wire guide portion 25 of the wiring head 17 fixed to the vicinity of the press-fitting blade 15 extends downward from both sides of the press-fitting blade 15 along the press-fitting blade retreating direction. The wire 5 delivered from the wire nozzle 13 is extended along the extending direction of the wire holding groove 3a over a length corresponding to the length of the wire holding groove 3a by a pair of wall portions 25a, 25a extending to the wire. A guide groove 27 for positioning is formed.

As shown in FIG. 3, the press-fitting blade 15 has a notch 15a having a width corresponding to the length of the wire holding groove 3a in an intermediate portion.
And two projections 15 on both sides of the notch 15a.
b, 15 b are pressed against the electric wire 5, and the electric wire 5 is pushed into the electric wire holding groove 3 a of the electric wire press fitting rib 3. Therefore, when the press-fitting blade 15 advances and pushes the wire 5 into the wire holding groove 3 a, at least a portion of the wire 5 pushed into the wire holding groove 3 a is guided by the guide groove 27 of the wire guide portion 25. It is reliably guided in the extending direction of the holding groove 3a.

Then, the wiring machine 11 is operated so that the electric wire 5 sent out from the electric wire nozzle 13 passes over the electric wire holding groove 3a of the electric wire press-fitting rib 3 arranged on the electric wire routing member 1. A head moving step of moving the wire head portion 17, and the wire 5 lying on the wire holding groove 3 a in the head moving step is pressed by the press-fitting blade 15 into the wire holding groove 3.
By repeating the wire pushing process into the a
A plurality of wire press-fitting ribs 3 arranged on a wire routing member 1
To form a conductor circuit.

First, when the wiring machine 11 starts the work for starting the routing process, the electric wire 5 guided to the electric wire feeding cylinder 29 is inserted into the electric wire nozzle 13. At this time, the electric wire 5 can be freely inserted between the nip roller 32 and the drive roller 31 by opening the nip roller 32 with respect to the drive roller 31. Then, the nip roller 32 and the drive roller 31 are closed, and the electric wire 35 is brought into a sandwiching state in which the electric wire 5 having a predetermined length can be sent out in accordance with the amount of rotational drive by the electric motor 35. Further, by driving the electric wire cutter 23 disposed above the electric wire nozzle 13 by the driving cylinder 24, the end of the electric wire sent out from the electric wire nozzle 13 was cut off, and the end of the electric wire 5 was trimmed to the cutter position. State. When the above preparation work is completed, the routing process can be started.

The operation of the wiring head 17 in the wiring processing of the wiring machine 11 will be described below. First, in a head moving step, the wiring head 17 is moved onto a target wire press-fitting rib 3 by a head moving means (not shown) (see FIG. 1). At this time, the electric wire 5 is sent out by the electric wire supply means 21 while measuring the length according to the moving distance of the wiring head 17.

When the wiring head 17 moves sequentially between the wire press-fitting ribs 3, 3, the wire 5 sent out from the wire nozzle 13 is inserted into the guide groove 27 of the wire guide 25, and 5 is regulated at least in the feeding direction at a portion inserted into the guide groove 27. Therefore, when the wiring head 17 is guided on the wire press-fitting rib 3 to be pressed next, the direction of the guide groove 27 of the wire guide portion 25 that determines the sending direction of the wire 5 is The wiring head 25 is moved so as to coincide with the extending direction of the wire holding groove 3a of the wire press-fitting rib 3 to be press-fitted, and at the same time, is rotated around the axis 19 to adjust the direction of the wire guide portion 25. Do

The guide groove 2 of the wire guide 25
When the direction of the wire 7 coincides with the extending direction of the wire holding groove 3a of the wire press-fitting rib 3, as shown in FIG.
7 is lowered as it is, and the lower ends of the pair of walls 25a, 25a of the electric wire guide 25 are brought closer to the upper end surfaces of the pair of opposing walls 3b, 3b of the electric wire press-fit rib 3 (see FIG. 6A). That is, the guide groove 27 of the wire guide portion 25 and the wire holding groove 3a of the wire press-fitting rib 3 face each other so as to be substantially in communication.

Next, in the wire pushing process, FIG.
As shown in (a), the guide groove 27 of the wire guide portion 25
By positioning the wire 5 on the wire holding groove 3a of the wire press-fitting rib 3, the wire 5 is positioned on the wire holding groove 3a, and then the press-fitting blade 15 is advanced by the press-fitting blade driving cylinder 33. 4), the electric wire 5 is pushed into the wire holding groove 3a while being guided by the wire guide portion 25 in the extending direction of the wire holding groove 3a.

If there is a possibility that a certain amount of tension may be applied to the electric wire 5 at the time of press-fitting, the gap between the driving roller 31 and the nip roller 32 of the electric wire supply means 21 is widened in advance to a predetermined value or more. When the press-fitting of the electric wire 5 is completed, as shown in FIG. 6C, the press-fitting blade 15 is returned to the initial position, and the driving roller 31 and the nip roller 32 are used for guiding to the next wire press-fitting rib 3. The electric wire 5 is held. Next, until the downstream end of the guide groove 27 in the wire guide portion 25 is disengaged from the wire holding groove 3a of the press-fitted wire press-fitting rib 3, the wire holding groove 3a is removed.
After the wiring head 17 is moved forward, the wiring head 17 is lowered by a predetermined amount, so that the electric wire 5 is securely inserted into the guide groove 27.

Then, while the electric wire 5 having a length corresponding to the moving distance of the wiring head 17 is being sent out by the electric wire supply means 21, the head moving means (not shown) again transmits the electric wire 5 as shown in FIG. 17 is moved onto the next target wire press-fit rib 3. By repeating the above-described head moving step and pushing step, a predetermined conductor circuit is arranged on the wire routing member 1. And wire cutter 2
By driving 3 by the drive cylinder 24, the end of the electric wire sent from the electric wire nozzle 13 is cut, and the wiring of the predetermined conductor circuit is completed.

Therefore, according to the wiring machine 11 of the present embodiment, the opposing wall 3 in which the electric wire 5 guided by the wiring head 17 forms the electric wire holding groove 3a of the electric wire press-in rib 3 to be press-fitted.
The upper edge of b, 3b is not crossed. Therefore, the work of press-fitting the electric wire 5 into each wire press-fitting rib 3 can be reliably performed, and the automation of the wiring work by the wiring machine 11 that forms the conductor circuit of a predetermined shape on the wire wiring member 1 can be facilitated. it can.

Next, as shown in FIG. 8 (a), the wire outlet 3c of the wire pinching groove 3a of the wire press-in rib 3 located upstream of the wire press-in rib 3 to be press-fitted is connected to the wire to be press-fitted. The operation of the wiring head 17 in the wiring process when the press-fit rib 3 is out of the extending direction L of the wire holding groove 3a will be described. First, as shown in FIG. 8A, by performing a pushing process, the press-fitting of the electric wire 5 into the wire holding groove 3 a of the upstream wire press-fitting rib 3 is completed.

Next, as shown in FIG. 8B, an axis 19 set near the downstream end of the guide groove 27 in the electric wire guide 25 as a center of rotation when the wiring head 17 is turned is press-fitted. The wiring head 17 is advanced along the wire holding groove 3a until the wire press-fit rib 3 is removed from the wire holding groove 3a. Thereafter, by lowering the wiring head 17 by a predetermined amount, the electric wire 5 is securely inserted into the guide groove 27. Next, as shown in FIG. 8C, the wiring head 17 is moved around the axis 19 until the wiring head 17 faces the wire inlet of the wire holding groove 3a of the wire press-fitting rib 3 to be pressed downstream. Turn.

As described above, when moving the wiring head 17 toward the wire press-fit rib 3 on the downstream side, the axis 1 set near the downstream end of the guide groove 27 in the wire guide 25 is used.
By rotating the wiring head 17 around the rotation center 9, the wire guide 25 does not apply excessive tension to the wire 5 inserted in the guide groove 27 of the wire guide 25, There is no possibility that the wire 5 press-fitted into the wire press-in rib 3 on the upstream side may fall off or the wire 5 inserted into the guide groove 27 may come off.

When the wiring head 17 has to be largely turned and there is a possibility that the upstream electric wire 5 may be pulled, the holding of the electric wire 5 by the driving roller 31 and the nip roller 32 is released, and if necessary, The electric wire 5 is sent out by the electric wire supply means 21 so that the electric wire 5
Can be prevented from acting on a predetermined tension or more.

Then, as shown in FIG. 9A, the wiring head 17 is moved until the axis 19 is located immediately before the wire entrance of the wire clamping groove 3a of the wire press-fitting rib 3 to be press-fitted downstream.
Then, the wiring head 17 located on the wire press-fitting rib 3 is swiveled around the axis 19, and as shown in FIG. Is adjusted so as to match the direction in which the wire holding groove 3a of the wire press-fit rib 3 extends.

At this time, the guide groove 2 of the wire guide 25
Even if the wiring head 17 is turned so that the wire 7 extends in the extending direction L of the wire holding groove 3a of the wire press-fitting rib 3 to be pressed, the wiring head 17 is rotated around the axis 19.
Is turned, the wire guide portion 25 does not apply an excessive tension to the wire 5 inserted in the guide groove 27, and the wire 5 inserted in the guide groove 27 comes off and the wire is pinched. There is no possibility that the support is not provided along the groove 3a. Of course, by releasing the pinching of the electric wire 5 by the drive roller 31 and the nip roller 32, or by sending out the electric wire 5 by the electric wire supply means 21 as necessary,
It is also possible to prevent a predetermined or more tension from acting on the electric wire 5.

The guide groove 2 of the wire guide 25
When the direction of the wire 7 coincides with the extending direction of the wire holding groove 3a of the wire press-fitting rib 3, the wiring head 17 is lowered as it is, and the lower ends of the pair of walls 25a, 25a of the wire guide 25 are connected to the wire press-fitting rib. 3 are brought close to the upper end surfaces of the pair of opposing walls 3b, 3b (see FIG. 6A).

Then, as shown in FIGS. 8 and 9, the wire outlet 3c of the wire pinching groove 3a of the wire press-in rib 3 positioned upstream of the wire press-in rib 3 to be press-fitted is pressed into the wire press-fitting of the wire to be press-fitted. Even when the rib 3 is deviated from the extending direction L of the wire holding groove 3a, the part of the wire 5 that is pushed into the press-fitting blade 15 has a delivery direction that follows the wire holding groove 3a by the guide groove 27 of the wire guide portion 25. It is corrected to a state, and is supported in a state in which it is exactly along the wire holding groove 3a. Then, in this state, the press-fitting blade 15 is advanced and the electric wire 5 along the electric wire holding groove 3a is pushed into the electric wire holding groove 3a while being guided by the guide groove 27. Press fit can be performed.

That is, in the wiring machine 11 of the present embodiment, the direction and the position of the electric wire 5 sent out from the electric wire nozzle 13 are determined by the electric wire guide portion 25 provided in the wiring head 17 in the electric wire pressing groove 3 of the electric wire press-fitting rib 3. Straightened along 3a,
The turning operation of the wiring head 17 enables accurate positioning on the wire holding groove 3a of the wire press-fit rib 3.
Therefore, even when the electric wire 5 is routed between the wire press-fitting ribs 3 with different installation directions, the induced wire 5 does not cross the upper end edges of the pair of opposing walls 3b, 3b of the wire press-fit rib 3. Pressing work to the wire press-fitting ribs 3 and 3 can be reliably performed, and automation of wiring work of the wire 5 can be facilitated.

Further, the wiring machine 11 of the present embodiment is similar to a conventional wiring machine for preventing the wires 5 already pressed into the wire press-in ribs 3 from falling off when the wiring head 17 turns. It is not necessary to perform an extra operation of sending out the electric wire or a moving operation of largely retracting the wiring head 17 from the electric wire press-fitting rib 3. Therefore, the wiring machine 11 of the present embodiment can be routed in the shortest route, so that the number of wiring steps can be reduced as compared with the conventional wiring machine, and the work efficiency can be improved.

Next, as shown in FIG. 10, when the installation surface 20 of the wire press-fitting rib 3 is an inclined surface,
When the wire 5 moves horizontally, an excessive tension acts on the wire 5, and the wire 5 already pressed into the wire press-fitting rib 3 may fall off. Therefore, the wiring head 17 is moved toward the downstream wire pressing rib 3.
If the wire 5 is sent out by the wire supply means 21 to give an appropriate extra length before the wire 5 is horizontally moved, or the holding of the wire 5 by the driving roller 31 and the nip roller 32 is released, Tension does not act on the electric wire 5 and good wiring is possible.

Further, as shown in FIG. 11, two wire press-fitting ribs 3, 3 arranged on the wire routing member are provided on the installation surfaces 20a, 20b having a large difference in height. The operation of the wiring head 17 in the rope processing will be described. First, as shown in FIG. 11A, by performing a pushing step, the press-fitting of the electric wire 5 into the wire holding groove 3 a of the upstream wire press-fitting rib 3 protruding from the installation surface 20 a is completed.

Next, as shown in FIG. 11 (b), while the electric wire 5 having a length corresponding to the moving distance of the wiring head 17 is sent out by the electric wire
Is moved horizontally, and the guide portion 25 is moved on the vertical line of the next target wire press-fitting rib 3 projecting from the installation surface 20b. After that, as shown in FIG. 11C, the electric wire 5 is inserted into the guide groove 27 and the wiring head 17 is moved.
Is lowered. At this time, the electric wire supply means 21 appropriately controls the feeding of the electric wire 5 so that the upstream electric wire 5 does not come into contact with the downstream edge of the guide groove 27 or come off from the guide groove 27.

Next, as shown in FIG. 11D, positioning is performed so that the direction of the guide groove 27 of the wire guide portion 25 coincides with the extending direction of the wire holding groove 3a of the wire press-fit rib 3. The lower end of the electric wire guide 25 is brought close to the upper end surface of the electric wire press fitting rib 3. Then, in the wire pushing step, as shown in FIG. 11 (e), the press-fitting blade 15 is advanced so that the wire 5 is guided by the guide groove 27 so that the wire holding groove 3 a is held.
Can be pushed into the wire holding groove 3a while being guided in the extending direction of the wire.

Therefore, the two electric wire press-fitting ribs 3, 3 arranged on the electric wire routing member are provided on the installation surface 20 having a large difference in elevation.
a, 20b, respectively, the guided wire 5 is connected to the pair of opposing walls 3 of the wire press-fit rib 3 on the downstream side.
Since the upper ends of the b and 3b do not cross, the press-fitting work into the electric wire press-fitting ribs 3 and 3 can be reliably performed, and automation of the wiring work of the electric wire 5 can be facilitated.

The wiring head in the wiring machine of the present invention,
The configurations of the electric wire feeding means, the electric wire sending portion, the press-fitting blade, the electric wire guide portion, and the like are not limited to the configuration of the above-described embodiment, but may take various forms based on the gist of the present invention. Nor.

[0046]

According to the wiring machine of the present invention, when the wiring head sequentially moves between the wire press-fitting ribs, the wire sent from the wire sending portion is inserted into the guide groove of the wire guide portion,
The sending direction of the electric wire is restricted at least at a portion inserted into the guide groove. Therefore, when the wiring head is guided on the wire press-fitting rib of the next press-fitting object, the guide groove of the wire guide portion that determines the sending direction of the wire is inserted into the wire of the wire press-fitting rib of the press-fitting object. The wiring head is moved so as to match the extending direction of the holding groove.

When the direction of the guide groove of the wire guide portion matches the extending direction of the wire holding groove of the wire press-fitting rib,
The wiring head is lowered as it is, so that the guide groove is substantially communicated with the wire holding groove. In this state, even when the wire outlet of the wire holding groove of the wire press-fitting rib located on the upstream side of the wire press-fitting rib of the press-fitting object is displaced from the extending direction of the wire holding groove of the wire-pressing rib of the press-fitting object, The wire at the portion pushed into the press-fitting blade is straightened by the guide groove of the wire guide portion into a straight line along the wire holding groove, and is supported accurately along the wire holding groove.

In this state, if the press-fitting blade is advanced to push the electric wire along the wire holding groove into the wire holding groove, the press-fitting can be performed reliably. Therefore, since the wire guided by the wiring head does not cross the upper edge of the opposing wall forming the wire holding groove of the wire press-fitting rib to be press-fitted, the work of press-fitting the wire into each wire press-fitting rib is surely performed. It is possible to facilitate the automation of a wiring operation by a wiring machine that forms a conductor circuit of a predetermined shape on a wire routing member.
