Since this is not performed, the structure can be significantly simplified.

(Example) Examples of the present invention will be described in detail below with reference to FIGS. 1 to 5. The automatic fiber arrangement device for multi-core cables of this embodiment has a core wire supply mechanism 3 that sequentially supplies the core wires 2 of the multi-core cable 1 to be separated in a row in a random order. This core wire supply mechanism 3
The core wires 2 are inserted in one row in a random order into the core wire alignment guide slit 6 formed in the direction perpendicular to the rotor fitting hole 5 of the substrate 4, and the rows of core wires 2 are pushed into the core wires. The plate 7 is pushed in by operating the cylinder 8, and the plates are sent out sequentially starting from the first one.

A disk-shaped rotor 9 is installed in the rotor fitting hole 5 of the substrate 4.
are rotatably fitted. Core wire insertion grooves 10 are formed on the outer periphery of the rotor 9 at predetermined intervals in the circumferential direction (90° intervals in this embodiment). The groove width and depth of each core wire insertion groove 10 are determined so that only one core wire 2 can be accommodated, and when each core wire insertion groove 10 faces the core wire supply mechanism 3, the first one is It is designed to be inserted separately one by one.

A rotating shaft 11 provided at the center of the rotor 9 is rotatably supported by brackets 12 supported on the upper and lower surfaces of the substrate 4 via bearings (not shown).

A fiber take-out slit 17 is formed in a direction perpendicular to the rotor 9 in a portion of the substrate 4 at a position 90° away from the position of the fiber alignment guide slit 6 in the rotational direction of the rotor 9 on the outer circumference of the rotor 9. There is.
The center of this slit 17 is a core wire take-out position 18.

While a certain core wire insertion groove 10 of the rotor 9 rotates from the position of the core wire alignment guide slit 6 to the core wire take-out position 18, the core wire 2 accommodated in the core wire insertion groove 10 is electrically detected by the detection means 19. A fiber identifier 20 is provided which identifies the wire number of the core wire 2 by searching for it. A metal blade is used as the detection means 19, the tip of which is inserted into the circumferential groove 9 on the outer periphery of the rotor 9.
A, the insulation coating of the core wire 2 in the core wire insertion groove 10 is broken to establish electrical continuity. The detection means 19 is fixed to the substrate 4. The core wire discriminator 20 uses a wire number discriminator main body 21 in which each core wire 2 on that side is connected to the other end of the multi-core cable 1 in a predetermined arrangement order, and detects continuity of the core wires 2 with its detection means 19. By searching and searching, the wire number of the core wire 2 is identified and identification wire number data is output.
