"Operation" According to the present invention, first, an electric wire is drawn out by the electric wire supply means, cut to a predetermined length, and bent into a U-shape.
Its both ends are held by the clamps of the conveying means (Fig. 1 f
a+).

Thereafter, the wire is intermittently conveyed by a conveying means,
Various wire processing means disposed along the path of the conveyance means sequentially perform the following processing on both ends of the U-shaped wire.

First, a heat-shrinkable outer tube is inserted into the end of the electric wire by the outer tube supply means (see FIG. 1 (b+)).

The jacket is semi-stripped to a predetermined length by the jacket stripping means (see FIG. 1, ICL).

The semi-stripped outer jacket is twisted in the opposite direction to the twist of the shield wire by the twist return means, and the twist of the shield wire is returned (see FIG. 1 (a+)).

The semi-stripped outer sheath is completely extracted from the end of the wire by the sheath removing means (see Figure 1 (el)).
.

Air is blown onto the end of the wire by the airbrush means, and the shield wire is separated from the core wire (see FIG. 1 ff+).

The shield wire separated from the core wire is twisted and bundled by the shield wire twisting means (see FIG. 1 (g, l)).

The whisker detection means grips the shield wire with a metal plate, grips the core wire with a metal brush, and energizes between them.
Detect the shield wire remaining on the core wire side (Fig. 1 fh
(see l).

The inner tube supply means covers the shield wire with a heat-shrinkable inner tube (see FIG. 1 (il)).

The inner tube heat shrink means blows hot air onto the inner tube, causing the inner tube to contract and come into close contact with the shield wire (see Fig. 1 fjl!@).

The forming means forms the core wire and the shield wire so that they are parallel to each other (see FIG. 1 (kl, fil)).

The tips of the core wire and the shield wire are stripped to a predetermined length by the inner sheath stripping means (see io+I in Figure 1).
.

Crimp terminals are attached to the tips of the core wire and the shield wire by the terminal crimping means (see Figure 1 in).

The outer tube positioning means places the outer tube at the branching portion of the core wire and the shield wire (see Figure io1).
.

Hot air is blown onto the outer tube by the outer tube heat shrinking means, causing the outer tube to shrink and come into close contact with the electric wire (first
(see figure fpl).

The thus obtained wire workpiece is removed from the clamp and discharged by the discharge means.

In each of the above steps, the greatest feature of the wire processing machine of the present invention is that the shield wire is gripped by a metal plate, the core wire is clamped by a metal brush, and current is passed between the two by the whisker detection means; The reason is that the shield wire remaining on the edge of the core is detected. In other words, when attempting to separate the core wire and shield wire of an electric wire and attach crimp terminals, etc. to each end, if even one shield wire remains attached to the core wire, it may cause a short circuit. Because it will be.

Therefore, according to the electric wire processing machine of the present invention, the above-mentioned electric wire processing can be performed automatically, and the shielded wire can be reliably separated from the core wire to obtain a highly reliable product. .
