A length cutting section 11 that stretches the wire group 1 in an inverted V-shape and cuts it to the desired length using a four-tooth 19; - Holds the wire group 1 that has been cut to the adjusted length in an inverted shape and transports it laterally; a transfer section 12, and a pressure welding station 28 in the middle of the transfer section 12;
A group of electric wires 1 and a connector 2 are provided in the
The press-contact connection part 18 for press-connecting the person 2B is constituted by the above-mentioned parts, and an automatic control circuit is incorporated in which each part is combined and arranged in the permutation and sequentially and continuously linked and operated.

The configuration and operation of each part will be explained in detail below.

First, the wire delivery section 10 consists of a straightener 14 for straightening the wires in the wire group 1, a delivery drum 15, and a laminate section 16, as shown in FIG. 1.2.
5 has an autorotation mechanism and winds the 1111s group 1 horizontally in parallel in the required widths and widths, pulls out the required 'WL line group 1 from the X-ray supply section 9 via the straightener 14, and laminates the 1111s group 1. The data is sent to the section 16. Then, in the laminating section 16, in order to stabilize the feeding posture of the wire group 1 and maintain the parallel pitch, the resin thin body 8 pulled out from the pair of resin film drums 17 is attached to the itgA group 10 as shown in FIG. It is configured to be heat-welded at the required location.

Note that 18 in the figure is a holding roller that supports the sending wire.

Next, as shown in FIGS. 1 to 8, the length adjustment/cutting section 11 includes a length roller 1 that accurately moves up and down in conjunction with a belt conveyor 21 provided vertically on a frame 20 erected in the form of a ladder.
9, a pair of auxiliary rollers 22B provided at both ends of the base of the frame 200, the laminate portion 16, and the frame 20.
A cutting part 24 of the wire group 1 is located between the wires and the auxiliary roller 22B, and a wire clamp body 28 reciprocates between the lower blade part 26 of the cutting part 24 and the auxiliary roller 22B on the other side of the frame 20. It is a provision. Then, the wire clamp body 28 clamps the end of the wire group 1 on the lower blade part 25 in the forward position (28v) shown in the figure, and moves the wire group 1 onto the auxiliary roller 22.
After that, the length roller 19 waiting at the lower end of the frame 20 rises, and the wire group 1 is pulled out between the length roller 19 and the auxiliary roller 22 A 2
2. Stretch it in an inverted V-shape using B, and
The length of the wire group 1 is accurately adjusted by the upward stroke of the wire group 1, and the wire group 1 of one group is cut to a required length by the cutting section 24. Specifically, the adjuster 19 is moved so that the two thin resin bodies 8, which are closely welded to the surface of the wire group 10 by the laminate portion 16, are located at both ends of the wire group 1 after cutting. The 19hc-method is stopped slightly below the position 19' for measuring the required length, and while the process is stopped, the resin thin body 8 is welded to the wire group 1, and after welding, the adjusting roller 19 cuts the laminate part 16. Part 2
4 and then stops. Immediately, the cutting section 24IC cuts the middle of the two thin resin bodies 8 that have moved below the cutting section 24 due to the secondary strike cutting, and cuts the intermediate part of the two thin resin bodies 8 to have the required length accurately. Electrode 1 with thin resin body 8 welded near both ends
! Form group 1. In order to avoid interference with the clamp body 28, the auxiliary view roller 22 member 22B and the lower blade portion 25 have a built-in retraction mechanism when the clamp body 2B moves forward and performs a clamping action.

Next, the transfer section 12 is attached to a traveling rail 27 provided at the upper end of the frame 20 perpendicularly to the frame 20, as shown in FIG.
A traveling trolley 80 having electric wire holding claws 29 is mounted,
The traveling trolley 80 can freely travel along the traveling rails 27. Further, at the lower part of the frame 20, a clamp claw 8 is provided which reciprocates on a platform 81 in parallel with the traveling trolley 80, and a clamp claw 8 is provided in front of the frame 20.
A pair of left and right conveying bodies 82 are provided, and are configured to clamp both ends of the wire group 1 in the vicinity of the above-mentioned paddle assisting roller 22m 22B immediately before cutting when the moving body 82 is in the forward position shown at 82'.

Then, when the electric wire group 1 is cut by the above-mentioned length cutting section 11, the above-mentioned traveling cart 80 and transfer body 82 do not catch the upper end of the inverted V-shaped electric wire group 1 on the wire holding claw 29. At the same time as transferring, clamp both ends of the wire group 1 with clamp claws 8.
8, the wire group 1 is held in an inverted position and transferred, and is stopped at a pressure welding stage 28 located in the middle of the traveling rail 27.

Next, as shown in FIG. 4, the pressure welding connection part 18 is connected to a press fit press 86 provided above the pressure welding position 85 of the pressure welding station 28, and the two connectors 2B are loaded one after another into the pressure welding body 85. Group of wires with connectors sent out to
7, and a parts feeder 8 filled with cover unit 5
8 and the cover unit 6 sequentially fed from the parts feeder 88
It is composed of a suction hand 89 that sequentially presses and sends out the wires 86 above the electric wire group 1, and two sets of the above-mentioned elements are arranged symmetrically so that they can be crimped on both ends of the wire group 1 at the same time.

Then, it is held in an inverted state by the transfer section 12,
ii When the wire group stops at the pressure welding station 28, both ends of the wire group 10 clamped by the clamp claws 88 of the transfer body 82 are connected to the connector 2A2 supplied to the pressure welding position 85.
Stop exactly on B. Subsequently, the suction hand 89 that has suctioned the cover unit 6 moves forward and presses the cover unit 5 with the cover body 8.

At the same time, the cover unit 5 is hooked to the two connectors 2B, and the connectors 2 are attached to both ends of the wire group 10.
A tis with a connector connected to the person 2B is molded.

When the above-described forming is completed, the traveling cart 80 and the transfer body 82, which have been temporarily stopped at the pressure welding stage tube 28, move to the terminal end of the transfer section 12, open the clamp, and move the connector-equipped wire group 1
is relayed to the next process.

The above-mentioned operations are sequentially and continuously performed.

According to the above-described automatic forming apparatus of the present invention, the wire group 1 is held in an inverted V-shape, purchased and cut, and is pressure-connected to the connector, and the three-dimensional space of the apparatus is utilized to process each puta cess. For example, 4. Q Q It is now possible to process extremely long electric wires of 9 mm or more, and these long electric wires can be smoothly transferred between processes without trouble and formed in a fast takt time, and automatic forming can be done in three-dimensional form. There are unique effects that can be achieved with a compact device due to the utilization of space.

Furthermore, according to the lengthening mechanism of the present invention having the above configuration, since the middle of the long electric wire is pushed up and stretched in an inverted V shape,
This has the advantage that the shoulder insertion speed is extremely quick, there is little spacing error due to variations in wire diameter, and the spacing accuracy is extremely high.
