Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an automatic fiber identification device for a multi-core cable that automatically identifies the wire number of each insulated core wire of the multi-core cable.

(Prior Art) Generally, a multi-core cable with a circular cross section called an I/0 cable is used for signal transmission between office automation equipment, but when connecting the end of the cable to the equipment, A flat connector, which is a connector for a flat cable, is used. Therefore, when attaching a flat connector to a cable terminal, it is necessary to arrange and connect each insulated core wire of a multi-core cable in a predetermined order.

In such a case, it is necessary to check the wire number of each insulated core wire of the multi-core cable and determine the arrangement order based on the wire number.

Conventionally, the wire number of each insulated core wire is identified by connecting each insulated core wire at one end of the multi-core cable to a core wire identifier in a predetermined wire number arrangement, and then identifying each insulated core wire at the other end of the multi-core cable. Insert the core wires one by one into the core wire insertion grooves on the outer periphery of the rotor, and in the process of feeding the insulated core wires as the rotor rotates, insert the knife-shaped detection electrode of the core wire identifier into the insulated core wires. The wire number of the insulated core wire was identified by establishing continuity.

(Problem to be solved by the invention) However, conventionally, the knife-shaped detection electrode was positioned from outside the outer periphery of the rotor with its cutting edge facing the surface of the rotor. When the cutting edge of the knife-shaped detection electrode bites into the insulated wire in the process of fitting it into the core wire insertion groove on the outer periphery of the rotor and rotating it to establish continuity, the insulated wire is pushed by the cutting edge and escapes toward the center of the rotor. However, there was a problem in that the cutting edge could not be sufficiently penetrated into the insulated wire.

An object of the present invention is to provide an automatic core identification device for multi-core cables that can reliably identify insulated wires.

(Means for solving the problem) The structure of the present invention to achieve the above purpose is as follows:
Referring to FIGS. 1 to 5, which correspond to embodiments, the present invention connects each insulated core wire 2 at one end of a multi-core cable 1 to a core wire identifier 20 in a predetermined wire number arrangement. , a process in which each insulated core wire 2 is sequentially inserted one by one into the core wire insertion groove 10 on the outer periphery of the rotor 9 on the other end side of the multi-core cable 1, and the insulated core wires 2 are fed as the rotor 9 rotates. In an automatic core identification device for a multi-core cable, the knife-shaped detection electrode 19 of the core wire identifier 20 is inserted into the insulated core wire 2 to establish continuity and identify the wire number of the insulated core wire 2.
The rotor 9 is characterized in that a circumferential groove 24 is provided on the outer periphery of the rotor 9 so as to cross the core wire insertion groove 10 and into which the cutting edge 19A of the knife-shaped detection electrode 19 is inserted.

(Function) In this way, the insulated core wire 2 supported by the rotor 9 crosses the knife-shaped detection electrode 19 while the rotor 9 is rotating, and the wire number of the insulated core wire 2 is automatically identified. At this time, since the knife-shaped detection electrode 19 is inserted into the circumferential groove 24 formed on the outer periphery of the rotor 9 at a position crossing the core wire insertion groove 10 on the outer periphery of the rotor 9, the knife-shaped detection electrode 19 Even if the insulated core wire 2 is pushed by the knife-shaped detection electrode 19 when it bites into the insulated core wire 2, it cannot escape in the direction in which it is pushed, and the knife-shaped detection electrode 19 reliably bites into the insulated core wire 2 to ensure continuity. can be taken.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 5. The automatic fiber identification device for multi-core cables of this embodiment has a core wire supply mechanism 3 that sequentially supplies the insulated core wires 2 of the multi-core cable 1 to be identified in a row in a random order. This core wire supply mechanism 3 inserts each insulated core wire 2 in a row in a random order into a core wire alignment guide slit 6 formed in a direction perpendicular to the rotor fitting hole 5 of a substrate 4, and The rows of wires 2 are pushed in by a core wire pushing plate 7 by operating a cylinder 8, and 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 (45° intervals in this embodiment). The groove width and depth of each core wire insertion groove 10 are determined so that only one insulated 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 the first one. It is now possible to separate and insert one article at a time from the beginning.

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).

The rotor 9 is intermittently rotated by a rotor rotation mechanism 13. This rotor rotation mechanism 13 includes a gear 14 fixed to the rotation shaft 11.
, a gear 15 that meshes with the gear 14, and a motor 16 that is supported by the bracket 12 and rotates the gear 15.

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 fiber alignment guide slit 6 in the rotational direction of the rotor 9 on the outer periphery 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 insulated core wire 2 accommodated in the core wire insertion groove 10 is inserted into the knife-shaped detection electrode 19. A core wire identifier 20 is provided which identifies the wire number of the insulated core wire 2 by establishing electrical continuity therewith. The knife-shaped detection electrode 19 is designed to break the insulation coating of the insulated core wire 2 in the core wire insertion groove 10 to establish electrical continuity. The knife-shaped detection electrode 19 is fitted into the recess 21A of the substrate 4 together with the electrode holder 21B and fixed with screws 22 and nuts 23. A circumferential groove 24 is formed across the core wire insertion groove 10 on the outer periphery of the rotor 9, which the cutting edge 19A of the knife-shaped detection electrode 19 faces, and the cutting edge 19A of the knife-shaped detection electrode 19 is inserted into the circumferential groove 24. It is. The angle between the cutting edge 19A and the bottom surface of the circumferential groove 24 is determined such that the side where the insulated core wire 2 enters is wide and the side where the insulated core wire 2 exits is narrow. The core wire discriminator 20 connects each insulated core wire 2 on one end side of the multi-core cable 1 via a connector 25 in a predetermined wire number arrangement, and detects continuity of the insulated core wire 2 with the aforementioned knife-shaped detection electrode 19. By doing so, the wire number of the insulated core wire 2 is identified and identification wire number data is output.

A core wire holder 26 is arranged diagonally below the substrate 4. The core wire holder 26 is attached to the holder substrate 2
A pair of comb-shaped core wire holders 28 installed on 7
These core wire holders 28 have core wire positioning insertion portions 29 consisting of a large number of grooves arranged in a one-to-one correspondence with each other and facing each other.

The fiber holder 26 positions the fiber holder based on the identification wire number data given from the fiber identifier 20 so that the fiber positioning insertion part 29 of the wire number is on standby at the fiber extraction position 18 on the outer periphery of the rotor 9. The position is determined by a mechanism 30. This core wire holder positioning mechanism 30 includes a positioning table 3 on which the core wire holder 26 is mounted.

The insulated core wire 2 carried by the rotor 9 to the wire take-out position 18 is taken out by a wire handling mechanism 36 installed opposite to that position, and the wire holder is placed on standby at the wire take-out position 18. It is designed to be inserted into the core wire positioning insertion section 29 of No. 26. The fiber handling mechanism 36 operates on the fiber handling hand 3 that is located on the line of the fiber take-out position 18.
7, a cylinder 38 that moves in the direction of arrow A or B to bring the fiber operating hand 37 into contact with and away from the rotor 9, and a cylinder 38 that moves the fiber operating hand 37 along with the cylinder 38 on the line of the fiber take-out position 18. Arrow C
Alternatively, it is composed of a cylinder 39 that moves up and down in the D direction, and a guide means 40 when the cylinder 39 expands and contracts. Both cylinders 38 and 39 constitute a moving means 41 for moving the core wire operating hand 37.

A pair of guides 42 are provided to straightly guide the insulated core wire 2 from the core wire extraction position 18 to the core positioning insertion portion 29 of the core wire holder 26 directly below the core wire extraction position 18 .

Next, its operation will be explained. The insulated core wires 2 arranged in a line in a random arrangement order in the core wire alignment guide slit 6 are separated one by one from the first one each time the rotor 9 rotates and the core wire insertion grooves 10 thereof face each other. . The insulated core wire 2 accommodated in the core wire insertion groove 10 is sequentially moved toward the core wire take-out position 18 as the rotor 9 rotates. During the movement, the insulated core wire 2 passes a knife-shaped detection electrode 19, and while it is held in the core wire insertion groove 10 so as not to escape, the knife-shaped detection electrode 19 insulates the insulated core wire 2. The sheath is broken to establish electrical continuity with the internal conductor, the wire number is determined by the wire identifier 20, and the identified wire number data is given to the pulse motor 35 of the wire holder positioning mechanism 30. The pulse motor 35 is driven by this identification wire number data, and the fiber holder 26 is moved together with the positioning table 31 so that the fiber positioning insertion section 29 corresponding to the identification wire number data is positioned at the fiber removal position 18. , positioning is performed. When the insulated core wire 2 reaches the core wire take-out position 18 as the rotor 9 rotates, a sensor (not shown) detects this and the cylinder 38 moves forward in the direction of the rotor 9, and the core wire operating hand 37
grips the insulated core wire 2 at the core wire take-out position 18, the cylinder 38 moves in a direction to retreat from the rotor 9, and the cylinder 39 moves to lower the wire operating hand 37 in the direction of arrow C, and the insulated core The wire 2 is positioned and inserted into the core wire positioning insertion portion 29 corresponding to the core wire take-out position 18 via the guide 42 .
When the positioning and insertion are completed, the fiber handling hand 37 is raised in the direction of arrow D. During this operation, as the rotor 9 rotates, the next core wire insertion groove 10
Identification of the insulated core wire 2 separated and inserted is performed in parallel, and based on the identified wire number data, the positioning of the core wire positioning insertion section 29 is similarly performed, and the insulated core wire relative to the core wire positioning insertion section 29 is identified. 2 positioning insertion is performed. In this way, after one insulated core wire 2 is taken out and before its positioning is completed,
Since the next insulated core wire 2 is identified in parallel,
The overall work time can be reduced.

(Effects of the invention) As explained above, the automatic core wire identification device for multi-core cables according to the present invention is provided with a circumferential groove on the outer periphery of the rotor in a direction that crosses the core wire insertion groove of the rotor. Since the knife-shaped detection electrode is inserted into the insulated wire, the rotor can prevent the insulated wire from escaping when the knife-shaped detection electrode bites into the insulated wire. The reliability of wire number identification can be improved. In addition, in the present invention, the cutting edge of the knife-shaped detection electrode is shaped to bite into the outer periphery of the rotor, but since a circumferential groove is provided in the circumferential direction on the outer periphery of the rotor into which the cutting edge bites, the cutting edge comes into contact with the rotor. This can prevent the rotation from being obstructed.
