Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a semi-automatic fiber arrangement device for a multi-core cable that arranges the core wires of a multi-core cable in a predetermined order.

[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 connector for cables is used. Therefore, when attaching a flat connector to a cable terminal, it is necessary to arrange and connect each core wire of a multi-core cable in a predetermined order.

In such cases, conventionally, a worker would pick out any one fiber from among the many cores of a multi-core cable, bring it to the sensor of a fiber identifier, identify the wire number, and then identify the wire. Based on the identification wire number data, a worker sequentially inserts and positions the core wires into the wire positioning insertion portions of the wire holder corresponding to the identified wire number data.

[Problems to be Solved by the Invention] However, with this method of positioning the core wire, there is a problem in that it is easy for an operator to erroneously insert the core wire into the adjacent core wire positioning insertion section. It was hot. In addition, the number of man-hours required by the workers increased, resulting in poor work efficiency.

SUMMARY OF THE INVENTION An object of the present invention is to provide a semi-automatic fiber arrangement device for multi-core cables that can prevent incorrect insertion even in a semi-automatic manner and has good workability.

[Means for solving the problems] The structure of the present invention for achieving the above object is as follows:
The present invention will be explained with reference to FIGS. 1 to 3 corresponding to embodiments. The present invention includes a fiber guide passage 2 through which any one of the fibers 4 of a multi-core cable 3 is guided and passed through. , a fiber identifier 5 which is provided with a sensor 5A in the middle of the fiber guide passage 2 and identifies the wire number of the fiber 4 by passing the fiber 4 therethrough;
Based on the identification wire number data given from the fiber identifier 5, the fiber holder 7 having a large number of fiber positioning insertion portions 10 is arranged so that the fiber positioning insertion portion 10 of the wire number is located in the fiber guide passage 2. The fiber holder positioning mechanism 11 includes a fiber holder positioning mechanism 11 that positions and moves the fiber holder so as to be on standby corresponding to the exit, and a shutter body 18 that closes the fiber guide passage 2.
The shutter mechanism 17 prevents the core wire 4 from passing until the zero positioning is completed.

[Operation] With this structure, the worker can simply connect the core wire 4.
It is only necessary to pass the wire through the core wire guide passage 2 from its entrance to its exit side. At this time, the fiber guide passage 2 is connected to the sensor 5A of the fiber identifier 5 and the shutter body 18 of the shutter mechanism 17 that prevents the fiber 4 from passing through.
The wire holder positioning mechanism 11 locates a specific core of the wire holder 7 based on the identified wire number data obtained by the wire identifier 5 identifying the wire number of the wire 4 passing through the wire. Until the wire positioning insertion part 10 is positioned at a position corresponding to the outlet of the wire guide passage 2, the shutter body 1 of the shutter mechanism 17
8 does not open, it is possible to prevent incorrect insertion of the core wire 4.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 3. As shown in the figure, the multi-core cable semi-automatic fiber arrangement device of this embodiment has a frame 1.
A core wire guide passage 2 is provided in the upper part of the frame 1 in a downward direction. This core wire guide passage 2 is designed to allow any one of the many core wires 4 of the multi-core cable 3 to pass therethrough while being guided. A sensor 5A of a fiber discriminator 5 is disposed in the middle of the fiber guide path 2. The sensor 5A of this embodiment consists of a knife-shaped electrode, with a part of its tip protruding into the core wire guide passage 2,
When the core wire 4 passes through, its insulation coating is broken to establish electrical continuity with the internal conductor. Core wire identifier 5
is connected to a connector 6 in which each core wire 4 on the other end side of the multi-core cable 3 is connected in a predetermined arrangement order, and by detecting continuity of the core wire 4 with a sensor 5A, the core wire 4 can be detected. The wire number is identified and identification wire number data is output.

A core wire holder 7 is arranged below the core wire guide passage 2. The core wire holder 7 has a pair of comb-shaped core wire holders 9 installed on a holder substrate 8, and these core wire holders 9 have core wire positioning insertion portions 10 consisting of a number of grooves that are mutually connected. The structure is such that they are provided in one-to-one correspondence.

The fiber holder 7 positions the fiber holder based on the identification wire number data given from the fiber identifier 5 so that the fiber positioning insertion part 10 of that wire number is waiting in a corresponding position at the exit of the fiber guide passage 2. The position is determined by a mechanism 11. This core wire holder positioning mechanism 11 includes a positioning table 12 on which the core wire holder 7 is mounted, a ball screw 14 screwed through a piece 13 under the positioning table 12, and a positioning table in a direction parallel to this. 12, and a pulse motor 16 that rotates the ball screw 14 based on core identification wire number data.

The frame 1 supports a shutter mechanism 17 that normally closes the fiber guide passage 2 and prevents the fiber 4 from passing until the fiber holder positioning mechanism 11 finishes positioning the fiber positioning insertion part 10. There is. The shutter mechanism 17 includes a shutter body 18 that is slidably supported on the frame 1 so as to be able to cross the fiber guide passage 2 and not cross it, and a driving means 19 that is a cylinder that drives the shutter body 18. The driving means 19 is driven by a signal output from the fiber identifier 5 when the timer is activated after the time when the fiber holder positioning mechanism 11 finishes positioning the fiber positioning insertion part 10. ing.

The multi-core cable 3 is supplied from a drum 20.

Next, its operation will be explained. The worker picks out any one fiber to be arranged from among the many core wires 4 of the multi-core cable 3, and pushes the core wire 4 down while applying tension to the fiber guide path 2, as shown in FIG. Pass it like this. When the core wire 4 passes the sensor 5A in the core wire guide passage 2, the sensor 5A, which is a knife-shaped electrode, breaks the insulation coating of the core wire 4 and establishes electrical continuity with the internal conductor. Thereby, the wire number of the core wire 4 is identified by the core wire identifier 5. After the core wire 4 passes through the sensor 5A, the shutter body 18 prevents it from passing further. When the wire number identification device 5 finishes identifying the wire number, it outputs the identified wire number data to the pulse motor 16 of the wire holder positioning mechanism 11. The pulse motor 16 is driven by this identification wire number data, and the fiber positioning insertion section 10 corresponding to the identification wire number data is moved into the fiber guide passage 2.
The core wire holder 7 is moved together with the positioning table 12 so as to correspond to the outlet, and positioning is performed. When the positioning of the fiber positioning insertion section 10 is completed, a shutter release signal is output from the fiber identifier 5 to the drive means 19 of the shutter mechanism 17, and the drive means 19 is activated to move the shutter body 18 backward. let As a result, the fiber guide passage 2 is opened, and when an operator presses down the fiber 4 in the fiber guide passage 2 while applying tension,
The core wire 4 escapes from the output of the core wire guide passage 2 and is inserted into the core wire positioning insertion section 10 waiting at the outlet of the core wire guide passage 2. In this manner, all the core wires 4 are inserted into specific core wire positioning insertion portions 10 of the core wire holder 7 according to their wire numbers, and arranged according to their wire numbers.

When the arrangement of the core wires 4 is completed, the multi-core table 3 is cut to the required length, the core wire holder 7 is removed from the positioning table 12, and in the next step, for example, each core wire is arranged in parallel between the core wire holders 9. 4 with adhesive tape so that the arrangement order and spacing are not disturbed, and in this state, the core wires 4 of the part fixed with the adhesive tape
Press fit into each blade-shaped terminal of the flat connector to connect to the flat connector.

The core wires 4 on the cut end side of the cut multi-core cable 3 can be arranged in the same way by connecting the flat connector attached in the previous step to the core wire identifier 5.

[Effects of the Invention] As explained above, in the semi-automatic fiber arrangement device for a multi-core cable according to the present invention, since the shutter body of the shutter mechanism is provided in the fiber guide passage, the shutter body of the shutter mechanism is provided in the fiber guide passage. The wire number of the core wire is identified by the core wire identifier, and based on the result, the core wire can be prevented from proceeding to the exit side until the core wire holder positioning mechanism finishes positioning the core wire positioning insertion part. . Therefore, the wire number of the wire is identified by the wire identifier, and the wire holder positioning mechanism is driven by the identified wire number data, so that a specific wire positioning insertion portion of the wire holder is aligned with the wire guide passage. The core wire can be kept on standby until it is positioned at a position corresponding to the outlet of the core wire, and the core wire can always be inserted into the correct core wire positioning insertion section. Therefore, according to the present invention, the operator simply passes the core wire through the core wire guide passage, waits the core wire at that position while the shutter body is in the closed state, and then waits at that position when the shutter body is in the open state. Furthermore, since all you have to do is move the core and insert it into the core positioning insertion part waiting at the exit, the work is very simple, has good workability, and can reliably prevent incorrect insertion, making it extremely easy to carry out. suitable for Further, according to the present invention, there is an advantage that the core wires can be arranged using inexpensive equipment without using an expensive robot or the like for handling the core wires.
