[0003] Under such circumstances, the wire harness is still being recycled, but the wire harness has many connectors at the ends of the electric wires, and it is not easy to separate the components. .

Therefore, in practice, the components are separated by a method called nugget processing. This nugget treatment is a method in which the wire harness is cut into whole pieces, roughly separated into metal and plastic by a vibration separator using the specific gravity difference, and only the metal part is taken out by mixing copper generated from electric wires and brass etc. generated from connectors. is there. The extracted mixed metal is processed and used as a copper alloy for decorative articles. However, the separation of the extracted mixed metal into copper and brass could not be performed for economic reasons because their specific gravities are very similar.

The wire harness dismantling machine of the present invention provides a wire harness having such a configuration,
The connector 3 is separated from the wire harness main body 1 by mechanical force.

FIG. 2 is a perspective view schematically showing the appearance of a wire harness dismantling machine according to one embodiment of the present invention. In the figure, reference numeral 10 denotes a transport conveyor, which comprises a transport roll and a guide roll as shown, and a pair of belt portions 11 which move on the outer circumference defined by these. Each of the pair of belt portions 11 moves in the direction of the arrow, and conveys the wire harness main body 1 while holding and fixing it.

In the vicinity of the conveyor 10, the connector 3
Are forcibly separated from the wire harness main body 1. The rotor 10 includes a rotor body 13 and a number of needle-like members 1 provided around the rotor body 13.
4, 15, and 16. The rotor body 13 has an elongated roll shape, the axial direction of which is parallel to the transport direction of the transport conveyor 10, and can be rotated clockwise in the figure at an appropriate rotational speed by a rotational driving force by a rotational drive system (not shown). Has become. In the present embodiment, the rotor section 12 is divided into three sections in the axial direction, and the needle-like members 14 have a relatively coarse pitch in the axial direction in the first section on the upstream side, and in the second section in the center in the first section on the upstream side. The needle members 15 are mounted at a medium pitch in the axial direction, and the needle members 16 are mounted at a relatively fine pitch in the third section on the downstream side. For example, the needle-like member 1
4 to 16 can be composed of a thick steel bar.
Reference numeral 14 denotes a pitch of 4 cm, reference numeral 15 denotes a pitch of 2 cm, reference numeral 16 denotes a pitch of about 1 cm, and the thickness is 14
The diameter at the m level, the diameter at 15 can be about 6 mm, and the diameter at 16 can be about 4 mm. Of course, these needle-like members 14 to 16
The thickness and the axial pitch are not limited to those illustrated here, but can be appropriately set according to the type and size of the connector 3 to be separated. The circumferential pitch of the needle-like members 14 to 16 may be a constant pitch as shown in the drawing, or may be random. The rotor unit 12 is rotatably attached to the support base B.

On the support base B, a curved plate-like member 17 is installed below the rotor section 12 along the outer peripheral shape of the rotor section 12. The curved plate-like member 17 has an arc-shaped cross section and extends parallel to the axial direction of the rotor section 12.
As shown in FIG. 3, the curved plate-like member 17 and the tips of the needle-like members 14, 15, 16 of the rotor portion 12
They are arranged with a certain gap. Needle member 14 ~

In the circumferential direction of the curved plate-like member 17, projections 18 for scraping off the separated connector 3 are provided at an appropriate pitch in a direction parallel to the rotor rotation axis. Is provided with a hole 19 for discharging to the outside of the dismantling machine. If the projections 18 are not perpendicular to the rotor body 13 but have a slight inclination against the rotation direction, that is, an inclination toward the conveyor side, the scraping efficiency is improved. Further, the curved plate-shaped member 17 may be provided with a guide portion G on the side of the conveyor.

Next, the operation of this embodiment will be described.
When the wire harness main body 1 and the connector 3 as shown in FIG. 1 are separated, the disassembling machine shown in FIG. 2 is used, and the wire harness is introduced into the dismantling machine as shown in FIG. That is, the wire harness main body 1 is conveyed while being sandwiched between the belt portions 11 of the conveyor 10, and is introduced by, for example, a manual operation so that the connector 3 is applied to the rotor 12 side. Then, the rotation of the rotor section 12 causes the needle-like members 14, 15,
The connector 16 is separated so as to tear off the connector 3, and the separated connector 3 hits the scraping projection 18 by the scraping projection 18, and is discharged and collected downward through the hole 19. FIG. 6 shows a state of the wire harness main body 1 from which the connector 3 is separated, and FIG. 7 shows a state of the separated connector 3.

In this embodiment, the rotor section 12 is divided into three sections as described above, and the pitches of the needle members 14, 15, 16 in the axial direction are different in each section. This state is shown in detail in FIG. 8 (cross-sectional view taken along the line XY in FIG. 3). The needle-like members 14 in the first section have a coarse pitch and are intended for separating large connectors, and the needle-like members 15 in the second section are for medium-pitch and medium-size connectors. The needle-like members 16 in the section (1) have a fine pitch and are intended for separating small connectors. With such a configuration, the connectors 3 having various dimensions can be separated. Therefore, according to the wire harness dismantling machine of the present embodiment, connectors having different sizes can be separated stepwise. After the connector 3 and the wire harness main body are separated from each other, normal recycling is performed by dividing each of them, and the brass generated from the connector 3 and the wire harness main body 1 are separated.
Is separated and recovered from copper. Also, connector 3
Plastic material and wire harness body or
It can also be separated from the resulting plastic material.

Although the present invention has been described based on one embodiment, the present invention is not limited to the above embodiment, and various modifications and changes can be made as described below. First, in the above-described embodiment, a needle-shaped member was used as the connector separating means, but the present invention is not limited to this. If the connector can be forcibly separated, a member having a claw or the like for tearing off, etc. Those having an appropriate shape can be used. Further, in the above embodiment, the rotor portion 12 is divided into three sections in the axial direction, and needle-shaped members having different cross-sectional dimensions and pitches are provided.
Only the pitch may be different, only the cross-sectional dimension may be different, or all may be the same. In the above embodiment, the rotor unit 12 is provided on one side. However, when automation is to be achieved, rotor units may be provided on both sides. Further, instead of the conveyor 10 of the above embodiment,
A transport conveyor as shown in FIG. 9 may be used. 2 in the figure
Reference numeral 0 denotes a plurality of projections for hooking and holding the wire harness main body.

[0014]

According to the present invention, since the above configuration is employed, the wire harness main body and the connector portion can be efficiently separated and each can be separately recycled, so that copper and brass can be separated and recovered. Become. In addition, a connector made of a special material can be separated from the plastic recycling side, and can be recycled separately from the plastic material on the wire harness main body side. Therefore, it can contribute to effective use of resources.
