SUMMARY OF THE INVENTION An object of the present invention is to provide an improved wire terminal tying device which can reliably prevent the above tying failure with a simple mechanism.

[0011]

In the wire terminal tying device according to the present invention, one end of the wire is connected between the terminal block of the bobbin and the wire holder outside the rotation area of the tying nozzle. And a wire terminal distributing and locking means for separating the wire ends.

[0012]

With this wire terminal tying device, when one end of the wire located between the terminal block of the bobbin and the wire holder is tied to a predetermined terminal pin by the tying nozzle, the other end is used. Since the terminal is separated from the rotation area of the tying nozzle by the sorting and locking means, it is possible to reliably prevent the tying failure caused by the tying nozzle getting caught by another terminal with a simple mechanism. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 to 3, each device of the illustrated embodiment has the same basic structure as the above-described pallet and wire terminal binding device.
Common parts are indicated by the same reference numerals. FIG. 1 partially shows the front side of the wire terminal tying device. Reference numeral 20 denotes a tying nozzle, 21 denotes a bearing that rotatably drives the tying nozzle 20, and extends in the X, Y, and Z-axis directions. 1 shows an aircraft moving to a predetermined position.

This wire terminal binding device is provided with a wire terminal sorting / locking means 30 in addition to the above-described mechanism. The wire terminal distributing and locking means 30 locks any terminal of the wire located between the terminal block 2 of the bobbin B fitted and supported by the bobbin holder 15 of the pallet P and the wire holder 16. The pin 31 is attached by fixing the bearing at the tip side of the pin holder 32 with the shaft tip of the sorting pin 31 facing downward in the Z-axis direction. Also, pin holder 3
2 is arranged so that the distribution pin 31 distributes and locks one end of the wire, and the other end is positioned so that the nozzle 20 can be entangled with the terminal pin by the tying nozzle 20; Fixed.

In the wire terminal tying device having such a configuration, as shown in FIG.
After the wire is wound around the bobbin shaft 3 of the bobbin B fitted and supported by the above, each end of each wire is entangled with the terminal pin while each end of the wire is sandwiched and supported by the wire holder 16. Applying baking process.

At this time, if the terminals W _{1 and} W _{2 of} the wires adjacent to each other between the terminal block 2 of the bobbin B and the wire holder 16 are narrow as shown in FIG. As 21 moves forward in the Y-axis direction and then moves downward in the Z-axis direction, the distribution pin 30 moves so as to cut between the terminals of the wire. Thereafter, for example, when processing circuited with the terminal pin 4a the start terminal W ₁ of the wire at the nozzle 20 tying earlier, X-axis direction body 21 of the wire terminal tying device moves away from the start terminal W ₁ wire Move slightly. With the movement of the body 21, the sorting pin 31 is distributed locking to separate the final terminal W ₂ of the wire from the beginning terminal W _1. At this time, since the terminals W ₁ and W ₂ of the wires are supported by the wire chuck via the wire holder 16, they do not come off from the wire holder 16. In the distribution state, since attaching the nozzle 20 tying the start terminal W ₁ of the wire tying terminal pin 4a, tying絡付the start terminal W ₂ of the wire in the nozzle 20 does not get caught the end terminal W ₂ of the wire Can be processed.

[0017] After the processing circuited with the start terminal W ₁ of the wire, the sorting pin 31 body 21 to the X-axis of the wire terminal tying device to disengage from the end terminal W ₂ of the wire above the Z-axis direction moving further, the sorting pin 31該機body 31 to beyond the end terminal W ₂ of the wire is moved in the X-axis direction.
Thereafter, the aircraft 21 so that tied nozzle 20 corresponds positioned end terminal W ₂ of the wire is moved downward in the Z axis direction, the nozzle 2 tying the fault with processing for the terminal pins 4b
0. It should be noted that which one of the above-mentioned terminals at the beginning and end of the wire is to be entangled first can be arbitrarily selected depending on the installation position of the distribution pin 31.

[0018]

As described above, according to the wire terminal tying device according to the present invention, any one of the ends of the wire is separated from the rotation area of the tying nozzle by the sorting and locking means, thereby separating the wire terminal. Since the entanglement process is performed, it is possible to reliably prevent the unnecessary entanglement of the wire terminal as the entanglement nozzle rotates around the axis of the terminal pin.
