An object of the present invention is to ensure the operation of separating one core wire from a large number of core wires in the above-mentioned "wire terminal arrangement device for multi-core cable."

The present invention will be explained below based on an embodiment of the fiber end arrangement device shown in FIGS. 2 to 12.

The fiber terminal arrangement device of the present invention has a multi-core cable 1
At one end, there is a jig 2 that holds the ends of the core wires 1a in an arbitrary arrangement order, almost parallel to each other and in a plane, and the core wires 1a held by the jig 2 are separated one by one from the other core wires 1a. a pick-up unit 3 to be separated;
The basic structure includes an arraying device 6 for identifying the core wires 1a separated by the pick-up unit 3 and transported by the transporting device 4, and arranging them in a predetermined arrangement in the mold 5.

The jig 2 is used to hold the ends of the core wires 1a at one end of the multi-core cable 1 at two locations spaced apart in the length direction, as shown in FIG. By inserting the core wires 1a, the core wires 1a can be pulled out almost parallel to each other, in a flat shape, and toward one end of the slit 7.

Further, above this jig 2, as shown in FIG.

The pickup unit 3 is provided at the top.

That is, the pick-up unit 3 includes a U-shaped moving frame 11 into which the ends of the aligned core wires 1a are inserted, a separating claw 12 that is movable in a direction intersecting the plane in which the core wires 1a are aligned, and a core. a presser plate 13 provided movably in the alignment direction of the lines 1a;
a detector 14 for detecting that the movable frame 11 moves and one core wire 1a at the end in the alignment direction is inserted into the movable frame 11; and the separation claw 1.
2 and drive devices 15 and 16, such as air cylinders, which move the holding plate 13 in the aforementioned directions, respectively.

Further, the operation of the pickup unit 3 is as follows:
It is controlled by a CPU 17 that controls the array device 6, and as shown in FIG. , a drive motor 9 is connected via a pulse generator 19.

Next, referring to FIG. 5 A to D, the operation of the pickup unit 3 and the CPU 17
Explain the functions of

() First, while raising the separation claw 12,
The presser plate 13 is moved to the left as shown in FIG. The pick-up unit 3 is brought close to the jig 2.

() When the detector 14 passes above the core wire 1a1 at the end in the alignment direction, the drive motor 9 is stopped on the condition that the pick-up unit 3 has moved the distance in the direction of the arrow, and the separating claw 12 is moved over the core wire 1a1. Position against.

Note that the above-mentioned moving distance can be expressed as =X+D/2+α, where X is the distance between the detector 14 and the separating claw 12, and D is the diameter of the core wire 1a. By setting the value of α in this equation according to the response delay of the detector 14 or the amount of movement due to the inertia of the pickup unit 3 after the drive motor 9 has stopped, the core wires 1a1 at the ends in the alignment direction can be A separation claw 12 is positioned between the core wire 1a1 and another core wire 1a2 adjacent to the core wire 1a1.

() As shown in FIG. 5C, the drive device 15 is operated to insert the separation claw 12 between the one core wire 1a1 and the other adjacent core wire 1a2.

() The drive device 16 is operated to move the holding plate 13 in the direction of the arrow in FIG.

() Move the pickup unit 3 in the opposite direction as shown in FIG. 5D.

Then, the core wires 1a held in the jig 2 are taken out one by one by the above operations () to (), and the multi-core cable 1 is held at the fixing point O of the multi-core cable 1 (that is, the multi-core cable 1 is held by a clamp described later). When the core wire 1 is moved to the vertically upper position of the
a is held by a holding member 4a (see FIG. 6) of the conveying device 4.

That is, this holding member 4a is provided at the tip of a pivot arm 21 that pivots around a shaft 20, and is approximately centered on the fixing point O in a plane perpendicular to the plane containing the core wire 1a. By turning, the core wire 1a is fed onto the moving table 22 of the arrangement device 6.

Furthermore, in the above-mentioned embodiment, by placing the jig 2 at a fixed position relative to the clamping member 4a, the pickup unit 3 tensions the core wire 1a as it separates and moves, and the clamping member 4a Care has been taken to ensure secure clamping.

The principle and conditions under which the pick-up unit 3 tensions the core wire 1a while moving it will be explained below with reference to FIG.

() Find an intersection point A between the plane and the turning locus of the holding member 4a within a plane including the core wire 1a, and draw an arc a within the plane with a radius equal to the distance r between this intersection A and the fixing point O. Draw on.

() The core wire 1a is held by the jig 2 inside this arc a.

() The direction of movement of the pickup unit 3 (this movement locus is shown by the chain line b in FIG. 7) is set in the direction intersecting the intersection A.

Then, in a relative relationship that satisfies the above conditions,
Since the distance from the fixing point O to the point B where the jig 2 holds the wire 1a is shorter than the distance r between OAs, the pick-up unit 3 applies tension to the wire 1a while moving the wire 1a, thereby ,
The slack of the wire 1a between the OBs is eliminated. Therefore, the core wire 1a is in a tensioned state and is transferred to the holding member 4a in a state where it is accurately positioned on the line segment OA.

Note that if the difference between r and is larger than the amount of slack in the core wire 1a, the core wire 1a will slip between the separating claw 12 of the pick-up unit 3 and the holding plate 13.
The holding point B of the core wire 1a moves toward the distal end side to absorb the above-mentioned dimensional difference. Therefore, with jig 2,
It is necessary to hold a portion slightly spaced apart from one end of the core wire 1a.

Furthermore, the mounting angle θ of the jig 2 (the moving direction of the pick-up unit 3) is set so that the outermost core wire 1
It is desirable to set approximately O<θ≦45° with respect to the angle at which the holding point B' of an intersects the arc a (that is, the line segment AC). Next, the arrangement device 6 will be explained.

That is, the moving table 22 of the arrangement device 6 is

Further, the movable table 22 is provided with an elevating plate 29 for supporting the core wire 1a when the movable table 22 is moved, and a pushing plate 30 for pushing down the core wire 1a downward through the slit 26, which can be freely moved up and down. At the same time, a pressing plate 31 presses the core wire 1a against the elevating plate 29, and a press plate 31 presses the core wire 1a against the lifting plate 29;
A pressing piece 32 for pressing a is provided so as to be movable in the horizontal direction.

Further, below the movable table 22, a mold 5 is provided in which grooves 33 into which the core wires 1a are fitted are arranged parallel to each other and on the same plane. A clamp 34 holding the cable 1 is attached.

These are drive devices such as air cylinders and solenoids that operate the push plates 30, respectively.

Further, the CPU 17 is connected to the core wire 1a of the multi-core cable 1 via the input/output interface 40.
The other ends (one end of the core wire 1a is held by the jig 2 as described above) are connected in a line,
By bringing the blade-shaped electrode 27 into contact with the core wire 1a on the moving table 22, it is possible to identify which one of the many core wires 1a included in the multi-core cable 1 is on the moving table 22. ing. Also,
The drive devices 35 to 39 are connected to the input/output interface 40, and the drive motor 25 is also connected via a pulse generator 41.

Next, the functions of the CPU 17 will be explained together with the operation of the array device 6.

() First, the moving table 22 is aligned concentrically with the mold 5, and the pressing pieces 28, 3
1 and 32 are evacuated, and the elevating plate 29 and the pushing plate 30 are raised.

When the blade-shaped electrode 27 contacts the core wire 1a, a specific terminal (not shown) of the interface 40 is electrically connected to the blade-shaped electrode 27 via the specific core wire 1a.
Thereby, the core wire 1a is identified.

(2) As shown in FIG. The moving table 22 is moved horizontally in the state in which the core wire 1 is
a are arranged above the grooves 33 in a predetermined order of the mold 5 based on the identification data. In general, the core wire 1a connected to the n-th terminal of the interface 40 is inserted into the n-th groove 33 from the end of the mold 5.
It is arranged above the .

() After positioning the conductor 1a as described above, the pressing piece 32 is operated to press it against the pushing plate 30, as shown in FIG. 10A and FIG. 11D.

() As shown in FIG.

Thereafter, by returning to the step () and repeating the steps () to (), a large number of core wires 1a are identified and held in the mold 5 in a predetermined order.

Then, after the core wires 1a held in the mold 5 are connected together with adhesive tape or the like and removed from the mold 5, one end (mold 5 side) and the other end (interface 40) of these core wires 1a are connected. By attaching a connector to the side), a connector used for wiring computers, etc. can be obtained.

Next, FIGS. 12A to 12D show another example of the operation of the pickup unit 3. The operation of this pickup unit will be explained below in order of process.

() First, as shown in Fig. 12A, the separation claw 1

In the above embodiment, the core wires 1a were arranged in the same arrangement at one end and the other end, but
By changing the reference data input to the CPU, it is also possible to arrange one end side and the other end side in a different relative relationship.

Further, by operating the present terminal arrangement device in the following order, a large number of connectors can be efficiently obtained from a long multi-core cable.

() One end of the long multi-core cable 1 is connected to the input/output interface 40, and the terminals of the core wires 1a are arranged at the other end of the multi-core cable 1.

() Cut the multi-core cable 1 to the required length from the other end.

() Connect the arranged terminals of the cut multi-core cable 1 to the input/output interface 40 to arrange the unarranged terminals.

() Repeat the operations from () to () above.

Furthermore, in the above embodiment, the mold is fixed and the movable table is moved to align the groove and the core wire, but the movable table may be fixed and the mold is moved. Further, in the above embodiment, the CPU controls the operation of the pickup unit, but a separate CPU may be provided specifically for controlling the operation of the pickup unit.

As is clear from the above explanation, the present invention has the core wires of a multi-core cable held by a clamp held in a jig in a state in which they are aligned in the same plane near one end. The core wires are held one by one by a pick-up unit that moves along the clamps, and are moved while being separated from the clamps. This has the effect that it can be reliably held between the two.
