As shown in FIGS. 1 and 2, the electric wire manufacturing apparatus of the present embodiment is an apparatus for manufacturing an electric wire W having a predetermined length with terminals 2 and 3 crimped to the front end and the rear end by aligning the front ends. .. This electric wire manufacturing apparatus includes a main equipment 10, a conveyor (electric wire conveying means) 20 as a sub-equipment connected to the main equipment 10, a work table 30 arranged adjacent to the conveyor 20, and a main holding as an electric wire holding means. A clip 24 and a control device (not shown) are provided as main components.

The main equipment 10 includes a wire feeding means 11 such as a feeding roller that feeds the wire W supplied from the wire supply source 1 forward while measuring the length, a wire cutting means 12 that cuts the wire W sent out by the wire feeding means 11. It includes a front end processing means 13 that crimps a terminal to the front end of the electric wire to be sent out by the electric wire feeding means 11, and a rear end processing means 14 that crimps a terminal to the rear end of the electric wire to be sent out by the electric wire sending means 11. The conveyor 20 carries the electric wire W sent out by the electric wire sending means 11 and conveys it along the sending direction A. The holding clip 24 holds the front end side of the electric wire W to be sent out by the electric wire feeding means 11 in the direction opposite to the feeding direction.

The control device has a function of controlling these means in general. That is, the control device controls the electric wire feeding means 11 and the conveyor 20 to send out the electric wire W having the terminal 2 attached to the front end by the front end processing means 13 to a first predetermined length (about 1 m which is easy to bend). .. Next, when it is confirmed that the temporary holding clip 21 as another electric wire holding means holds the front end side of the electric wire W in the direction opposite to the electric wire feeding direction A, the electric wire feeding means 11 and the conveyor 20 are controlled. The electric wire W is further sent out for a second predetermined length (the remaining length of the total length). After that, the electric wire cutting means 12 is made to cut the electric wire W at the position where the second predetermined length is sent out.

Next, the flow of the electric wire manufacturing process by the electric wire manufacturing apparatus of the first embodiment will be described in detail with reference to FIGS. 1 and 2 (a) to (h).

(A) The electric wire W supplied from the electric wire supply source 1 is set in the main equipment 10.

(B) In this state, when the operator H presses the operation switch 101, the main equipment 10 operates the front end processing means 13 to crimp the terminal 2 to the front end of the electric wire W. The crimping is performed by inserting the front end of the electric wire W into the front end processing means 13 with a chuck (not shown). Next, the electric wire W to which the terminal 2 is crimped to the front end is measured by a first predetermined length (about 1 m that the worker H can easily bend in the next step), and the conveyor 20 can be conveyed along the delivery direction A. Send out on top. After that, the main equipment 10 and the conveyor 20 are automatically stopped.

(C) The worker H holds the front end side of the electric wire W.

(D) The worker H bends the held electric wire W into a U shape so that the front end side is opposite to the feeding direction A and is held by the temporary holding clip 21. The temporary holding clip 21 is closed by pressing the clip closing switch 102 to hold the electric wire W.

Here, as the electric wire holding means, the main holding clip (main holding means) 24 for holding the front end side of the plurality of worked electric wires W (W0), which will be described later, and the main holding clip 24 are arranged above the main holding clip 24. A temporary holding clip 21 for holding the front end side of one electric wire W (W1) being operated is provided. The temporary holding clip 21 is movable in the front-rear direction and the up-down direction along the feeding direction A of the electric wire, and holds and holds the front end side of the electric wire W whose terminal 2 is crimped to the front end in the direction opposite to the feeding direction A. It is provided so that it can be released.

Further, an optical sensor 23 is provided to detect that the front end side of the electric wire W held by the temporary holding clip 21 moves to the rear opposite to the sending direction A of the electric wire and reaches the receiving position by the main holding clip 24. ing. In FIG. 2, the optical sensor 23 is omitted except for (f) and (g) in order to make each process easy to understand. The same applies to other embodiments.

The control device moves the temporary holding clip 21 to the rear opposite to the feeding direction when the temporary holding clip 21 holds the front end side of the electric wire W in the direction opposite to the feeding direction A. After that, when the optical sensor 23 detects that the front end side of the electric wire W has reached the receiving position by the main holding clip 24, the temporary holding clip 21 is lowered to turn the front end side of the electric wire W into the main holding clip 24. Hand over and hold.

That is, when the operator H presses the restart switch 103 after the state of (d) above, as in (e), the temporary holding clip 21 moves along the rail 22 and advances to the main equipment 10 side. ..

(F) When the tip of the terminal 2 is detected by the optical sensor 23, the temporary holding clip 21 stops moving.

(G) Then, the temporary holding clip 21 descends at the stopped position. A main holding clip 24 for holding a plurality of electric wires W (W0) that have been worked together is arranged under the temporary holding clip 21, and receives and holds the electric wire W from the temporary holding clip 21. As a result, the electric wire W is held with the front ends aligned.

The electric wire W0 is transferred from the temporary holding clip 21 to the main holding clip 24 as shown in FIG.
When the temporary holding clip 21 reaches the delivery position to the main holding clip 24 as in (b-1), the main holding clip 24 opens as in (b-2) and is temporarily held as shown in (b-3). The holding clip 21 is lowered to insert the electric wire W0 into the electric wire holding space of the main holding clip 24. Next, the main holding clip 24 is closed as shown in (b-4), the temporary holding clip 21 is opened as shown in (b-5), and finally the temporary holding clip 21 after delivery is shown as shown in (b-6). Clip 21 rises to its original height.

(H) Further, when the worker H presses the restart switch 103 in the step (e) above, the main equipment 10 and the conveyor 20 resume operation, and the main equipment 10 has the remaining length of the electric wire W (the first). The length of 2) is measured and sent to the conveyor 20, and the electric wire W is cut at that position by the electric wire cutting means 12. Then, the terminal 3 is crimped to the rear end of the electric wire W by the rear end processing means 14, and the rear end of the electric wire W is sent out to the conveyor 20. The main equipment 10 and the conveyor 20 stop when the rear end of the electric wire W is placed on the conveyor 20. After that, the worker H sequentially puts the electric wires W together in the vicinity of the worker H on the work table 30 (around the temporary holding clip 21).

By repeating the above steps, the front ends of the electric wires can be aligned while manufacturing the electric wires.

According to the electric wire manufacturing apparatus of the present embodiment, when the electric wire W is sent out by the first predetermined length, the electric wire W is curved in a U shape so that the front end side of the electric wire W is in the direction opposite to the electric wire sending direction. Hold. Then, in that state, the electric wire W is sent out by the remaining second predetermined length, so that the length of the conveyor 20 (electric wire conveying means) can be shortened to about half of the total length of the electric wire. Further, since the means for holding the front end of the electric wire W (main holding clip 24, etc.) is only provided, it is not necessary to move the means for holding both ends of the electric wire W significantly as in the conventional example, and the equipment is not enlarged. The equipment can be simplified and the working time can be shortened.

In particular, according to the electric wire manufacturing apparatus of the present embodiment, the position of the electric wire W held by the temporary holding clip 21 on the front end side can be determined by the optical sensor 23, so that the operator can attach the temporary holding clip 21 to the front end of the electric wire W. By simply holding the side, it is not necessary to finely position the front end side of the electric wire W.

By the way, as shown in FIG. 4A, when the main holding clip 24 is in a form of holding the electric wire between the pair of arms so as to hold the electric wire, the electric wire located on the center side of the electric wire bundle is attached to the electric wire from the arm. Since it becomes difficult to transmit the holding force of the electric wire, it is conceivable that the electric wire W (W0) slips and the tip position S of the electric wire shifts as shown in FIG. 4 (b).

Therefore, in the electric wire manufacturing apparatus according to the second embodiment, this point is improved.
5A and 5B are explanatory views of an electric wire manufacturing process by the electric wire manufacturing apparatus according to the second embodiment of the present invention, and FIG. 5A is a plan view for explaining a process performed instead of the process of FIG. 1D. 5 (b) is a side view, and FIG. 5 (c) is a front view. Further, FIG. 6 is an enlarged view of the main holding clip of FIG. 5 (c).

As shown in FIGS. 5 and 6, in the second embodiment, as the main holding clip 25 (electric wire holding means), a pair of holding plates 25a and 25a facing each other with a gap D substantially the same as the thickness of the electric wire W are provided. It is provided. Further, the electric wire pushing plate 26 that can move up and down above the gap D between the pair of holding plates 25a and 25a and pushes the electric wire W (W1) into the gap D between the pair of holding plates 25a and 25a by descending. It is provided.

When the electric wire manufacturing apparatus of this embodiment is used, the worker H bends the held electric wire W1 into a U shape, makes the front end side of the electric wire W1 in the direction opposite to the direction in which the electric wire W1 is sent, and holds the electric wire W1. Bring it above the clip 25. At that stage, the operator presses the restart switch 103. Then, the electric wire pushing plate 26 on the holding plates 25a and 25a is lowered to push the electric wire W1 into the gap D between the pair of holding plates 25a and 25a of the main holding clip 25.

The electric wire pushing plate 26 lowers with a constant force, lowers for a certain period of time, and then rises. Due to this structure, the push-in wire W1 is lowered until it comes into contact with the uppermost wire W0 already held between the holding plates 25a and 25a, and the pushing force of the wire push-in plate 26 is weaker than that, so that the wire is wire. W is not pushed in, and after a certain period of time, the electric wire pushing plate 26 goes up. By repeating this operation, the electric wires W are held in a row in the vertical direction without any gap.

As shown in FIG. 6, elastic rubber plates 25b and 25b are attached to the facing surfaces of the pair of holding plates 25a. The distance between the rubber plates 25b and 25b facing each other is set to be narrower than the diameter of the electric wire W. The electric wire W is sandwiched there and held. By holding the electric wires W in a row, the holding force can be evenly transmitted to all the electric wires W, the electric wires can be prevented from slipping, and the misalignment of the tip of the electric wires can be prevented.

In the subsequent steps, as shown in FIG. 2H, when the operator presses the restart switch 103, the main equipment 10 and the conveyor 20 resume operation, and the main equipment 10 is connected to the electric wire. The remaining length of W (second predetermined length) is measured and sent to the conveyor 20, and the electric wire W is cut at that position by the electric wire cutting means 12. Then, the terminal 3 is crimped to the rear end of the electric wire W by the rear end processing means 14, and the rear end of the electric wire W is sent out to the conveyor 20. The main equipment 10 and the conveyor 20 stop when the rear end of the electric wire W is placed on the conveyor 20. After that, the worker H sequentially puts the electric wires W together in the vicinity of the worker H on the work table 30 (around the temporary holding clip 21).

According to the electric wire manufacturing apparatus of the second embodiment, the electric wires W can be arranged in a row in the gap D between the pair of holding plates 25a and 25a, so that all the electric wires W have the holding force by the holding plates 25a and 25a. Can be evenly applied, the sliding movement of the electric wire W can be prevented, and the deviation of the front end position of the electric wire W can be prevented.

FIG. 7 is an explanatory view of an electric wire manufacturing process by the electric wire manufacturing apparatus according to the third embodiment of the present invention, and FIG. 7 (a) is a plane for explaining a process to be performed instead in the process of FIG. 1 (d). 7 (b) is a plan view for explaining the next step, FIG. 7 (c) is a plan view for further explaining the next step, and FIG. 7 (d) is a plan view for explaining the next step. It is a side view of time.

A temporary holding clip 21 for holding the front end side of the cable 21 is provided. The temporary holding clip 21 is provided so as to be movable in the vertical direction and to hold and release the front end side of the electric wire whose terminal is crimped to the front end in the direction opposite to the feeding direction. Further, an optical sensor 27 for detecting that the front end side of the electric wire W has been moved to the holdable position of the temporary holding clip 21 is provided.

When the optical sensor 27 detects that the front end side of the electric wire W has been moved to the holdable position of the temporary holding clip, the control device of the electric wire manufacturing apparatus of this embodiment uses the temporary holding clip 21 to hold the front end side of the electric wire W. After holding, the temporary holding clip 21 is lowered, and the front end side of the electric wire W is handed over to the main holding clip 24 and held.

That is, when using the electric wire manufacturing apparatus of the present embodiment, as shown in FIG. 7A, the worker H bends the held electric wire W1 in a U shape, and the front end side is sent out. And bring it to the position of the temporary holding clip 21.

Then, as shown in FIG. 7B, the optical sensor 27 detects that the front end side of the electric wire W has been moved to the holdable position of the temporary holding clip 21, and the temporary holding clip 21 closes and holds the electric wire W. Subsequently, as shown in FIGS. 7 (c) and 7 (d), the temporary holding clip 21 is lowered, and the electric wire is delivered to the main holding clip 24 waiting on the lower side. As a result, the electric wire W can be held with the front ends aligned. The procedure of delivery is the same as that described in the first embodiment.

In the subsequent steps, as shown in FIG. 2H, when the operator presses the restart switch 103, the main equipment 10 and the conveyor 20 resume operation, and the main equipment 10 is connected to the electric wire. The remaining length of W (second predetermined length) is measured and sent to the conveyor 20, and the electric wire W is cut at that position by the electric wire cutting means 12. Then, the terminal 3 is crimped to the rear end of the electric wire W by the rear end processing means 14, and the rear end of the electric wire W is sent out to the conveyor 20. The main equipment 10 and the conveyor 20 stop when the rear end of the electric wire W is placed on the conveyor 20. After that, the worker H sequentially puts the electric wires W together in the vicinity of the worker H on the work table 30 (around the temporary holding clip 21).

According to the electric wire manufacturing apparatus according to the third embodiment, when the worker H brings the front end of the electric wire W to the position of the temporary holding clip 21, the temporary holding clip 21 automatically receives the signal of the optical sensor 27. After temporarily holding the front end side of the electric wire W, it can be handed over to the main holding clip 24. Therefore, the worker H can automatically deliver the front end side of the electric wire W to the main holding clip 24 only by bringing the front end of the electric wire W to the position of the temporary holding clip 21.
