Abstract

PROBLEM TO BE SOLVED: To perform automatic working on a two-core shielding wire. SOLUTION: A two-core shielding wire is worked automatically by clamping the cores W1 and W2 of the wire exposed through the removable of the end section of the sheath of the wire and intermittently carrying the wire. In the course of this automatic working, the cores W1 and W2 are treated after the cores W1 and W2 have been straightened at a first station S1. Since various kinds of treatments are performed after the cores W1 and W2 have been straightened, the positioning and length adjustment of the cores W1 and W2 can be made easy as much as possible in the succeeding processes.

[0001]

[0001] The present invention relates to an apparatus and a method for processing a two-core shielded wire.

[0002]

2. Description of the Related Art Generally, as a wire processing apparatus, an apparatus which performs an automatic or semi-automatic process such as peeling a terminal of a covered electric wire, attaching a rubber stopper, and crimping a terminal fitting is widely known. . On the other hand, in recent years, two-core shielded wires have been used in electric wiring systems.
This two-core shielded wire is used for a sensor or the like that detects the phase angle of the crankshaft of the engine,
It is obtained by covering two sheathed wires (hereinafter referred to as "core wires") twisted with each other with a sheath.

[0003]

In processing the above-described two-core shielded wire, prior to the stripping or the terminal crimping, the end of the sheath is stripped to expose the core wire, and the core wire is exposed. It was necessary to untwist the exposed portion of the wire. At this time, due to the high rigidity of the core wire, the twisted core wire often has a twist habit,
Did not get used to automatic processing.

In addition, since it is often necessary to simultaneously process the core wire that is bifurcated from the sheath, automatic processing is also difficult from this point. The present invention has been made in view of the above problems, and has as its object to provide an apparatus and a method for processing a two-core shielded wire that can automatically process the two-core shielded wire.

[0005]

The slit 72 is formed in a substantially bottleneck shape in which the lower side is greatly opened, so that the core wires W1 and W2 that are wider than the specified dimensions while the holding plates 57 and 58 are open. Can be accommodated in the slit 72, and the holding plates 57, 58
Is closed, the core wires W1 and W2 are guided to the upper portion 72A of the narrow slit 72 to be narrowed down, whereby dimensional control can be performed. In the illustrated embodiment, a pair of long holes 74 extending vertically long are formed in the space regulating plate 71, and are fixed by bolts 75 passing through the long holes 74, so that the vertical height (slit upper portion 72A (Up and down position) can be adjusted.

The station S1 in which the core wire straightening device 40 is disposed also serves as a station where the worker P mounts the two-core shielded wire W on the shielded wire transport mechanism 20. Here, in conjunction with the timing at which the shield line transport mechanism 20 intermittently transports the clamp device 30,
The core wire straightening device 40 operates as follows. First, as shown in FIG. 8, in the initial state, the movable table 42
Is moved back forward and is close to the clamp device 30,
Each of the pressure plates 57 and 58 stops in a state where they are open to each other.

Referring also to FIG. 1, when the clamp device 30 is temporarily stopped in front of the core wire straightening device 40 by the intermittent revolving operation of the chain device 21, the worker P moves the core wire W
1. The two-core shielded wire W in which W2 is exposed in a forked shape is attached to the clamp device 30, and a foot switch (not shown) is operated to clamp the wire (see FIG. 5A). Thus, the core wires W1 and W2 are disposed between the pressing plates 57 and 58 through the slits 72 of the interval regulating plate 71 as shown in FIG.

As shown in FIG. 9, when the two-core shielded wire W is clamped, the core wire straightening device 40 operates the air cylinder 47 to bring the two lifting plates 49 and 50 closer to each other. As a result, the core wires W1 and W2 are
7 and 58, and the pinching operation narrows down the portion 72A above the slit of the gap regulating plate 71, thereby regulating the gap. Nipping plates 57, 58
When the pair clamps the core wires W1 and W2, the motor 62 operates to reciprocate the clamping plates 57 and 58 left and right.
Thereby, each core wire W1, W2 is connected to the holding plates 49, 50.
, The twisting habit is corrected by this handling operation.

As shown in FIG. 10, the pressure plates 57, 5
In parallel with the handling operation 8, the air cylinder 45 arranged in the main body 11 slowly moves the movable table 42 backward. As a result, the core wires W1 and W2 are
It is pulled backward while being handled by 7, 58, and receives tension. Here, since the core wires W1 and W2 are firmly clamped at fixed positions by the clamp device 30, the pressing plates 5
Slippage occurs between the core wires W1 and W2 and the core wires W1 and W2, and the pressing plates 57 and 58 are relatively separated from the core wires W1 and W2. With this separating operation, the gap regulating plate 71 is also displaced relative to the core wires W1, W2.
Slides the core wires W1 and W2 in the longitudinal direction to handle the core wires W1 and W2, and forms the so-called core wires W1 and W2 while regulating the facing distance between the two core wires W1 and W2. As a result, the core wires W1 and W2 extend linearly and parallel while maintaining the prescribed facing distance, and move to the next step.

When the movable table 42 moves to the end defined by the concave portion 41 formed in the support side plate 41 of the main body 11, the motor 62 stops, and the reciprocating movement of the pressing plates 57, 58 is stopped. By operating the air cylinder 47 and driving the lifting plates 49 and 50 in directions away from each other, the pressing plates 57 and 58
1. Return to the release position to release W2. Thereafter, the air cylinder 45 is operated to move the movable table 42 back and return it forward, whereby the core wire straightening device 40 returns to the initial state.

Next, referring to FIG. 11 et seq., The two-core shielded wire W that has completed the straightening process at the shielded wire straightening station S1 is conveyed to a rubber plug insertion station S2.
The rubber plug insertion device 80 arranged in this station S2

As shown in FIG. 11, the rubber plug G is embodied by the parts feeder 91 in a state where the small diameter side of the rubber plug G faces upward and the core wire insertion hole G1 is opened (see FIG. 13). The paper is fed to the front of the main body 11. As shown in FIG. 11, the feeder portion 92 for feeding the rubber plug G has the rubber plugs G aligned in two rows in the same posture by two parallel feeding grooves 93 and 94, and
Feeding forward. A delivery unit 95 attached to the bottom 82 of the main body frame 81 faces the front end portion of the feeder 92. This delivery unit 9
5 includes a slider 97 having a pair of pockets 96 for receiving the rubber stopper G, and an air cylinder 98 capable of reciprocating the slider 97 in the front-rear direction. The air cylinder 98 causes the pocket portion 9 of the slider 97 to move.
6 is opposed to the corresponding feeding groove 93, and the receiving position for receiving the rubber plug G, and the pocket portion 96 is displaced to the downstream side in the feeding direction of the two-core shielded wire W and received by the pickup unit 100 described below. The slider 97 reciprocates between the supply position for supplying the rubber stopper G and the supply position. In the illustrated example, a block body 85 is fixed to the bottom portion 82 of the main body frame 81, and is adjacent to the feeder portion 92. The slider 97 is set so as to be displaced to the supply position at a position almost in sliding contact with the front end face of the block body 85, whereby the pocket portion 96 of the slider 97 is moved to the block position when displaced to the supply position. The rubber plug G, which is shielded by the front end surface of the pocket 85 and accommodated in the pocket 96, can be detached only upward. The feeder unit 92 always feeds the rubber plug G forward by vibration during operation, but when the slider 97 is displaced to the supply posture, the slider 97 itself feeds the feed grooves 93 and 94. The shielding prevents the rubber stopper G from falling from the feeding grooves 93 and 94.
