Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic wire separation device for a multi-core cable that separates the core wires of a multi-core cable one by one.

(Prior art) Generally, a multi-core cable with a circular cross section called an I/O cable is used for signal transmission between office automation equipment. A flat type connector, which is a connector for type cables, is used. Therefore, when attaching a flat connector to a cable terminal, it is necessary to arrange and connect a large number of core wires in a predetermined order.

In order to arrange the core wires of a multi-core cable in a predetermined order, it is necessary to separate each core wire of the multi-core cable one by one in a pre-process.

As an automatic fiber separation device for multi-core cables used in such cases, there is a structure shown in Japanese Utility Model Application Laid-Open No. 60-59172. In this device, the core wires to be separated are arranged in a line by a core wire supply mechanism, the position of the core wires held in the core wire supply mechanism is detected by a detector, and the detection signal is sent to a central processing unit. A positioning signal is sent to the positioning drive mechanism, and the positioning drive mechanism positions the core wire clamping mechanism so that the clamp claw is positioned between the first core wire and the next core wire. In this state, a clamp claw is inserted between the first core wire and the next core wire to separate the first core wire from the next core wire.

(Problems to be Solved by the Invention) However, such a structure has a problem in that it becomes complicated and requires a sophisticated control method, resulting in high costs.

An object of the present invention is to simplify the structure, and
An object of the present invention is to provide an automatic wire separation device for a multi-core cable that can easily separate the wires.

(Means for solving the problems) The structure of the present invention for achieving the above object is as follows:
The present invention will be described with reference to FIGS. 1 and 2, which correspond to embodiments. It has a core wire insertion groove 10 into which the core wire 2 is inserted one by one, and when the core wire insertion groove 10 faces the tip of the core wire supply mechanism 3, the core wire insertion groove 1
The rotor 9 includes a rotor 9 into which only the leading core wire 2 is separately inserted into the rotor 9, and a rotor rotation mechanism 14 that rotates the rotor 9.

(Function) With this configuration, only the leading wire 2 of the wire supply mechanism 3 can be separated and inserted into the wire insertion groove 10 of the rotor 9, making it easy to mechanically insert the wire. Can be separated.

(Example) Examples of the present invention will be described in detail below with reference to FIGS. 1 and 2. As shown in the figure, the automatic fiber separation device for multi-core cables of this embodiment has a core wire supply mechanism 3 that aligns the core wires 2 of the multi-core cable 1 in a line and sequentially feeds them out from the top. This core wire supply mechanism 3 inserts each core wire 2 in one 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,
These rows of core wires 2 are pushed in by a wire pushing plate 7 by operating a cylinder 8, and are sent out one after another 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. The groove width and depth of each core wire insertion groove 10 are determined so that only one core wire 2 can be accommodated,
When each core wire insertion groove 10 faces the core wire supply mechanism 3, the core wires are separated and inserted one by one starting from the first one.

A rotating shaft 11 provided at the center of the rotor 9 has a bearing 1 mounted on a bracket 12 supported on the bottom surface of the substrate 4.
It is rotatably supported via 3.

The rotor 9 is intermittently rotated by a rotor rotation mechanism 14 in pitches of the core wire insertion grooves 10. This rotor rotation mechanism 14 includes a ratchet wheel 15 and an arm 16 fixed to a rotating shaft 11.
The pawl 19 is pivoted to the arm 16 by a pin 17 and biased by a spring 18 so that its tip engages with the ratchet wheel 15, and a cylinder 20 rotates the arm 16. The teeth of the ratchet wheel 15 are provided to correspond to the core wire insertion grooves 10 of the rotor 9.

A fiber take-out slit 21 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 rotation direction of the rotor 9 on the outer periphery of the rotor 9. There is.

A fiber handling hand 22, which will be described later, is disposed at the position of the fiber take-out slit 21, and is adapted to grasp the fiber 2 from the fiber insertion groove 10 of the rotor 9.

Next, a description will be given of an operation for separating the core wires 2 using such an automatic core wire separation device for a multi-core cable.
The core wires 2 of the multi-core cable 1 are inserted into the core wire alignment guide slit 6 in advance in one row in a random order. Next, by operating the cylinder 8, insert the cable pushing plate 7 into the cable alignment guide slit 6, push the aligned cables 2 toward the rotor 9, and insert the leading cable 2 into the cable insertion groove 10 of the rotor 9. . in this case,
Since the core wire insertion groove 10 is configured such that only one core wire 2 can be inserted, only one core wire 2 is inserted separately. After the plate 7 presses the aligned core wires 2 for a certain period of time, it is moved back by operating the cylinder 8. When the cylinder 8 moves backward, the cylinder 20 moves forward in conjunction with this, causing the arm 16 to rotate counterclockwise. As a result, the rotor 9 is rotated together with the ratchet wheel 15 by one pitch of the fiber insertion groove 10, and then the fiber insertion groove 10 is opposed to the fiber alignment guide slit 6, and in the same way, one fiber 2 is inserted into the fiber insertion groove 10. It is inserted into the core wire insertion groove 10. In this manner, as the rotor 9 rotates, the aligned core wires 2 are separated and inserted one by one into the core wire insertion grooves 10 on the outer periphery of the rotor 9. Core wire insertion groove 1 of rotor 9 housing core wire 2
0 corresponds to the core wire take-out slit 21, the core wire operating hand 22 protrudes to grasp the core wire 2 and take it out.

Note that the plate 7 may be configured to press the aligned core wires 2 at all times.

Furthermore, it goes without saying that the position of the fiber take-out slit 21 does not have to be at 90 degrees with respect to the position of the fiber alignment guide slit 6.

FIGS. 3 and 4 show the automatic fiber separation device 23 of the present invention described above and the fiber hand device 2 in the subsequent process.
4 shows an example of the configuration of an automatic cable separation device that combines the cable positioning device 25 and the cable positioning device 25. Each fiber 2 randomly aligned in the fiber alignment guide slit 6 is identified by a wire number one by one by a fiber identification device (not shown), and is stored in a storage section. The fiber identification device uses a wire number discriminator in which each fiber on that side is connected to the other end of the multi-core cable 1 in a predetermined arrangement order, and uses the detection means (for example, a knife-shaped electrode) to align the fibers. The randomly arranged core wires 2 in the guide slit 6 are
Each core wire 2 is tested by checking continuity one by one.
The wire number is identified and stored in the storage unit. The fiber positioning device 25 has a fiber holder 27 mounted on a positioning table 26.
The core wire holder 27 is a pair of comb-shaped core wire holders 2.
8, and both core wire holders 28 are disposed facing each other with their respective core wire insertion grooves 29 corresponding to each other one-to-one. The positioning table 26 is a positioning drive mechanism 33 consisting of a screw screw 30 screwed into a part of the table 26, a guide 31 parallel to this, and a pulse motor 32 that rotates the screw screw 30. A specific fiber insertion groove 29 is positioned and moved based on identification data from a fiber identification device. The core wire hand device 24 moves the core wire operating hand 22 located on the center line 34 to a cylinder 35 that moves in a direction toward and away from the rotor 9 on the center line 34 , and It is composed of a cylinder 36 that raises and lowers the line operation hand 22 together with a cylinder 35.

Next, its operation will be explained. The randomly arranged core wires 2 in the core wire alignment guide slit 6 are identified by the wire number for each wire by the fiber identification device as described above. The aligned core wires 2 are separated one by one by the core wire insertion groove 10 of the rotor 9 and then passed through the core wire take-out slit 2.
Moved to 1. When the core wire 2 is moved to the slit 21, this is detected by a detector (not shown), and the core wire operating hand 22 advances toward the rotor 9 on the center line 34 due to the action of the cylinder 35, and the core wire 2 is moved to the slit 21. , and is also retreated in the direction away from the rotor 9 on the center line 34. Next, the cylinder 36 is actuated, and the fiber operating hand 22 that has gripped the core wire 2 moves to the cylinder 35.
At the same time, it is lowered on the center line 34. In parallel with this, the positioning drive mechanism 33
is driven, and the core wire 2 is positioned so that the core wire insertion groove 29 of the core wire holder 28 into which the core wire 2 is to be inserted is located on the center line 34. Therefore, when the wire operating hand 22, which has grasped the wire 2 and retreated on the center line 34, descends on the center line 34, the wire 2 is inserted into the wire insertion groove 29 on the center line 34. The core wires 2 randomly arranged in this way are identified by their wire numbers and arranged in the core wire holder 27 according to the wire numbers.

(Effects of the Invention) As explained above, the automatic fiber separation device for a multi-core cable according to the present invention is configured such that the fiber insertion groove of the rotor separates and accommodates only the leading fiber of the fiber supply mechanism. This makes manufacturing simple, and the core wires can be easily separated without using sophisticated control methods.
