There is. Then, these electrodes 16 are simultaneously moved up and down by the drive mechanism 17 composed of a fluid pressure cylinder,
Each of the conductors 2 of the tape electric wire 1 is brought into contact with and separated from each other.

On the other hand, the control unit 18 includes the cutter 14
And each electrode 16, or electrical connection between each electrode 16,

First, the tape electric wire 1 is conveyed toward the downstream side while being held by the belt conveyor 19 and the pressing roller 20 of the conveying means 11, and is conveyed to a position where the portion of the tape electric wire 1 to be cut faces the cutting means 12. The transport means 11
Stop the operation of.

This conveyance amount is determined by the light emitted from the light projector 21a to the light receiver 21b in the position detector 21 being blocked by the insulator 3 of the tape electric wire 1 when the tape electric wire 1 is conveyed to the position. Also, the operation of the conveying means 11 is stopped by the control signal from the control unit 18 which is detected.

After stopping the transport of the tape electric wire 1 in this way,
As shown in FIG. 3 (A), the cutter 14 and each electrode 16 are lowered toward the conductor 2 of the tape electric wire 1 to bring each electrode 16 into contact with the other end of the conductor 2, and By continuously lowering the cutter 14, as shown in FIG. 3 (B), one ends of the plurality of conductors 2 are cut at the same time, and in this state, the relay 23 is switched to the disconnection detection mode.

If the conductor 2 is broken, the conductor 2
By disconnecting the electrical connection between the electrode 16 and the cutter 14 which are in contact with the above, the above-mentioned disconnection is detected and the control unit 18 causes the indicator R
The defective wire discharge mechanism 24 is operated to display the defect of the cut tape wire 1, and the table 25 of the defective wire discharge mechanism 24 is swung to break the tape wire 1. 1 Removed from its regular transport path.

Furthermore, if the above-mentioned disconnection is not detected,
The cutter 14 is raised by the control unit 18 to connect the electrodes 16 to the conductor 2 as shown in FIG. 3 (C).
The cutter 14 is separated from the conductor 2 in the state of being in contact with, and the relay 23 is switched to the cross-link detection mode (this mode is shown in FIG. 2).

From this, when a voltage is applied between the adjacent electrodes 16, in the case where there is crosstalk between the adjacent conductors 2,
The cross-linking is detected by detecting the current flowing between the both electrodes 16, and thereafter, similarly to the case where there is a disconnection, the display on the display R and the defective wire discharging mechanism 24 discharge the defective electric wire. .

On the other hand, when there is no cross-linking, the electrodes 16 are raised and separated from the conductors 2, and then the cut tape electric wire 1 is conveyed to a storage case or the like in the subsequent stage for the next cutting and inspection process. Transition.

However, according to the manufacturing apparatus 10 of the present embodiment configured as described above, the tape wire 1 can be inspected for disconnection or cross-linking on the tape wire 1 manufacturing line.

Moreover, since one component of the cutting means 12 is used as a part of the detecting means 13, the structure is simplified, and even when applied to an existing manufacturing apparatus, it can be applied with a small structural change.

Further, as described above, since the inspection line is incorporated as a part of the manufacturing line and a part of the components of the manufacturing line is used for the inspection line, not only the 100% inspection is easy, but also the 100% inspection is involved. The increase in manufacturing time is significantly suppressed.

For example, the tape electric wire 1 applied to this manufacturing apparatus 10 is
The conductor 2 may be a round wire, a flat wire, a single wire, a twisted wire, or the like. The number of cores is arbitrary.

Furthermore, in the above-described embodiment, the example in which the conductor 2 is completely exposed between the insulators 3 is shown. Instead of this, for example, as shown in FIG. It is also possible to apply it to the tape electric wire 1 in which the insulating tape 28 is attached to the side surface to regulate the position of the conductor 2 and ensure the insulation.
