Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an automatic wire arrangement device for multi-core cables that automatically arranges each core wire of the multi-core cable in a fan shape on a comb-shaped core wire holder. It is.

(Prior art) Generally, a multi-core cable with a circular cross section called a /0 cable is used for signal transmission between office automation equipment. A flat connector is used. Therefore, when attaching a flat connector to a cable terminal, each core of the multi-core cable is inserted into the corresponding core holding groove of the comb-shaped core wire holder in sequence, and each core is automatically fan-shaped. You will need to do some sorting work.

A conventional automatic fiber arrangement device for multi-core cables that performs this kind of work places a comb-shaped core holder in a direction perpendicular to the tip of the multi-core cable, and arranges a comb-shaped core wire holder that is guided out from the tip of the multi-core cable. Each of the core wires is placed in an automatic fiber separation mechanism installed above the tip of the multi-core cable, and the fibers are separated one by one in sequence, and each of the separated core wires is placed one by one in a fiber handling mechanism. While grasping and lowering the core wire to the specific core wire holding groove of the core wire holder, a pair of wires provided straddling the core wire automatic separating mechanism and the core wire holder are used. The structure was such that each of the core wires was automatically arranged in sequence in the core wire holder by being guided by the guiding action of a core wire guide means consisting of mutually parallel rods and inserted into the specific core wire holding groove.

(Problem to be solved by the invention) However, in such conventional automatic fiber arrangement devices for multi-core cables, the fibers are guided out from the tip of the multi-core cable and set in the automatic fiber separation mechanism above it. Since each core wire is arranged in a fan shape in a comb-shaped core wire holder, there is a certain amount of leeway in the length of the lead-out from the tip of the multi-core cable. A part of the expanded core protrudes into the core wire guide slit between the bars of the core wire guide means consisting of a pair of rods, and is later grasped by the core wire handling mechanism and pushed through the core wire guide slit. There was a problem in that it obstructed the progress of the core wire as it descended, causing the core wire to become stuck and unable to descend, or causing the wire to break.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic wire arrangement device for a multi-core cable that can prevent wire failures in the wire guide means.

(Means for solving the problem) The structure of the present invention to achieve the above purpose is as follows:
The present invention will be explained with reference to FIGS. 1 to 3 corresponding to the embodiment. In the present invention, a comb-shaped core holder 3 is disposed perpendicularly to the tip of the multi-core cable 1, and the multi-core cable 1 Each of the core wires led out from the tip of the multi-core cable 1 is set in the automatic fiber separation mechanism 20 installed above the tip of the multi-core cable 1 and separated one by one, and each of the separated core wires 2 is separated one by one. While the core wires 2 are grasped one by one by the wire handling mechanism 22 and lowered to a specific wire holding groove 5 of the wire holder 3, the core wires 2 are moved to the wire automatic separation mechanism 20.
The core wires 2 are guided by the guiding action of the core wire guide means 28 provided across the core wire holder 3 and inserted into the specific core wire holding groove 5 to guide each core wire 2 to the core wire holder 3. In the automatic wire arrangement device for a multi-core cable, the wire guide means 28 is arranged to automatically arrange each of the core wires 2 and the core wires rising from the tip of the multi-core cable 1 to the automatic wire separation mechanism 20. It is constituted by a partition plate 29 that partitions from the handling mechanism 22, and a core wire guide slit 30 provided in the partition plate 29, and the partition plate 29
is characterized in that it is curved so as to be concave with respect to the rising portion of each core wire 2.

(Function) In this way, since the wire guide means 28 is constituted by the partition plate 29, the middle portion of the rising core wire 2 is prevented from expanding and protruding toward the wire handling mechanism 22 side. Further, this partition plate 29 is curved so as to be concave with respect to the rising portion of each core wire 2, and since a core wire guide slit 30 is formed in this divider plate 29, the core wire guide slit 30 is also a partition. The cable guide slit 30 is curved by the plate 29 and moves away from the middle part of the rising cable 2, so that even if the middle part of the rising cable 2 expands, the cable guide slit 30
This prevents the cable from entering the cable and prevents the cable 2 from getting in the way of the cable 2 being gripped by the cable handling mechanism 22 and descending.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 3. The automatic fiber arrangement device for multi-core cables of this embodiment has a core wire supply mechanism 11 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 1
Reference numeral 1 denotes a core wire alignment guide slit 14 formed in a direction perpendicular to the rotor fitting hole 13 of the substrate 12.
Insert each core wire 2 in one row, press the row of core wires 2 by operating a core wire pressing means (not shown),
The data are sent out sequentially starting from the first one.

A disk-shaped rotor 15 is rotatably fitted into the rotor fitting hole 13 of the substrate 12 . Rotor 1
5 at predetermined intervals in the circumferential direction (in this example,
Core wire insertion grooves 16 are formed at 45° intervals.
The groove width and depth of each core wire insertion groove 16 are determined so that only one core wire 2 can be accommodated, and when each core wire insertion groove 16 faces the core wire supply mechanism 11, the first one is It is designed to be inserted separately one by one.

The rotor 15 is intermittently rotated by a rotor rotation mechanism 17.

Core wire alignment guide slit 1 on the outer periphery of the rotor 15
A core wire take-out slit 18 is formed in a portion of the substrate 12 at a position 90° away from position 4 in the rotational direction of the rotor 15 in a direction perpendicular to the rotor 15. The center of this slit 18 is a core wire take-out position 19.

These core wire supply mechanism 11, substrate 12, core wire alignment guide slit 14, rotor 15, core wire insertion groove 16, and rotor rotation mechanism 17 allow each core wire 2 of multi-core cable 1 to be transported one by one. This constitutes an automatic cable separation mechanism 20 for separation.

Diagonally below the substrate 12, first and second core holders 3 and 4 are mounted on a holder substrate 7 and arranged.

The first and second wire holders 3 and 4 determine the wire holding grooves 5 and 6 of the wire number at the wire extraction position on the outer periphery of the rotor 15 based on identification wire number data given from a wire identifier (not shown). The wire holder positioning mechanism (of which only the positioning board 21 is shown) positions the wire holder so that it is on standby at 19.

The core wire 2 carried by the rotor 15 to the core wire take-out position 19 is taken out by the core wire handling mechanism 22 installed opposite to the core wire take-out position 19. It is designed to be inserted into the core wire holding grooves 5 and 6 of the core wire holders 3 and 4 of No. 2. The fiber handling mechanism 22 includes a fiber handling hand 23 existing on the line of the fiber extraction position 19 and a cylinder that moves in the direction of arrow A or B to bring the fiber handling hand 23 into contact with and away from the rotor 9. 24, and a cylinder 25 that moves the fiber operating hand 23 up and down in the direction of arrow C or D together with the cylinder 24 on the line of the fiber removal position 19.
and a guide means 26 when the cylinder 25 expands and contracts. A moving means 2 for moving the core wire operating hand 23 using both cylinders 24 and 25.

Automatic wire separation mechanism 20 and first wire holder 3
A core wire guide means 28 is provided in the portion between. The fiber guiding means 28 includes a partition plate 29 that partitions each fiber 2 rising from the tip of the multi-core cable 1 to the fiber automatic separation mechanism 20 and the fiber handling mechanism 22, and a partition plate 29 that partitions the fiber handling mechanism 22. A wire guide slit 30 is formed in a vertical direction and guides the wire 2 straight to a specific wire holding groove 5, 6 of the first and second wire holders 3, 4,
In particular, the partition plate 29 is curved so as to be concave with respect to the rising portion of each core wire 2.

Next, its operation will be explained. The core wires 2 are aligned in a line within the core wire alignment guide slit 14.
are separated one by one from the leading one each time the rotor 15 rotates and the core wire insertion grooves 16 face each other. The core wire 2 accommodated in the core wire insertion groove 16 is sequentially moved toward the core wire take-out position 19 as the rotor 15 rotates. During the movement, the core wire 2 passes a detection means (not shown), and the detection means consisting of a blade breaks the insulation coating of the core wire 2 and conduction is established with the internal conductor. A signal is applied to a core wire identifier (not shown) on the side opposite to this continuity check end where each core wire 2 of the multi-core cable 1 is connected in a known arrangement state, and the wire number of the core wire 2 is determined by the wire number. This is determined by a fiber identifier, and the identified wire number data is given to a fiber holder positioning mechanism (not shown). The wire holder positioning mechanism is driven by this identification wire number data, and the wire holders 3 and 4 are positioned so that the wire holding grooves 5 and 6 corresponding to the identification wire number data are positioned at the wire take-out position 19. table 21
and positioning is performed.

When the core wire 2 reaches the core wire take-out position 18 as the rotor 15 rotates, a sensor (not shown) detects this, the cylinder 24 moves forward in the direction of arrow A, and the fiber operating hand 23 moves to the core wire take-out position 18.
grips the core wire 2, the cylinder 24 moves backward in the direction of arrow B, and the cylinder 25 moves the core wire operating hand 2.
3 is lowered in the direction of arrow C, and at this time, the core wire 2 is straightly passed through the core wire guide slit 30 of the core wire guide means 28 into the core wire holding grooves 5 and 6 corresponding to the core wire take-out position 19. Guided and inserted. At this time, the fiber operating hand 23 descends diagonally from above when viewed from the fiber holders 3 and 4, so
The core wire 2 is first inserted into the core wire holding groove 5 of the core wire holder 3, and then inserted into the core wire holding groove 6 of the core wire holder 4. When the wire operating hand 23 is further lowered, tension is applied to the wire 2 and the wire is pushed into the bottoms of the wire holding grooves 5 and 6 while taking up the slack.

Although the above-mentioned embodiment shows the case where there are two core wire holders, the present invention is not limited to this, and it goes without saying that the number of core wire holders may be one.

(Effects of the invention) As explained above, in the automatic fiber arrangement device for multi-core cables according to the present invention, since the fiber guiding means is composed of a partition plate, the intermediate portions of the rising fibers are expanded and It is possible to prevent the wire from protruding into the wire gundling mechanism, thereby preventing it from interfering with the wire arrangement work. In particular, this partition plate is curved so as to be concave with respect to the rising portion of each core wire, and a core wire guide slit is formed in this partition plate, so that the core wire guide slit is also curved in the same direction, and the rise center Therefore, even if the middle part of the rising core wire expands, it will not enter the core guide slit, and will no longer interfere with the core wire being gripped by the core wire handling mechanism and descending. Accidents such as the core wire stopping to descend or being cut can be prevented.
