[Industrial applications]

 The present invention relates to a core wire supply device in an automatic arranging machine that conducts a continuity test on each core wire of a multi-core cable and arranges the core wires at a predetermined position. The present invention relates to a core wire supply device for supplying to the mechanism side.

[0002]

[Prior Art]

 Conventionally, as a core wire supply device for an automatic arranging machine, a core wire aligner having a core wire arranging groove in which a plurality of core wires of a multi-core cable are arranged adjacent to each other in parallel, a separating claw and a holding plate are provided. It is known to have a moving frame that moves and a sensor that detects that a core wire has been inserted inside when the moving frame moves (see, for example, JP-A-60-91580).

In the core wire supply device having such a structure, the movable frame is moved to the core wire aligner side by the air cylinder, and the sensor detects the core wire located at the end of the core wire alignment groove of the core wire aligner. The separating claw is inserted between the core wire at the end and the adjacent core wire, and the pressing plate moves forward to clamp the core wire between the pressing plate and the separating claw. Then, the movable frame is retracted while holding the core wire and positioned at the conduction inspection position.

[Problems to be solved by the device]

 However, in the conventional core wire supply device, the core wire, which is arranged at a predetermined position in the core wire arranging groove of the core wire arranging orthogonally to the groove, is placed at a predetermined position by contact with the separation claw. It can change. For this reason, the separating claw does not enter between the end core wire and the adjacent core wire, so that a mistake in pinching the core wire occurs and the automatic alignment machine stops. In addition, since the separation claw sometimes contacts the core wire so as to press it, there is a drawback that the core wire is damaged. The present invention has been made to solve such a point, and provides a core wire supply device for an automatic array machine capable of reliably supplying the core wire to the continuity inspection side without damaging the core wire. is there.

[0005]

[Means for Solving the Problems]

 The core wire supply device for an automatic array machine of the present invention is a core wire aligner having a core wire arrangement groove in which a plurality of core wires of a multi-core cable are arranged in parallel. An elastic pressing means for elastically applying a pressing force to the plurality of core wires toward the core wire is provided, and a core wire chuck means for inserting the core wire located at the other end of the groove into the insertion hole is provided. Each time is taken out from the core wire arranging groove, the movement control means is made to move forward by at least the outer diameter of the core wire against the elastic force of the elastic pressing means.

[0006]

[Action]

 The movement control means advances the core wire chuck means at least by an amount corresponding to the outer diameter of the core wire every time the core wires are taken out from the core wire arranging groove. Therefore, the core wire at the end is securely inserted into the engagement hole of the core chuck means by the pressing force of the elastic pressing means. Therefore, by retracting the cord chuck means, each cord can be reliably supplied to the conduction inspection position.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall configuration diagram of a core wire supply device according to the present invention, and FIG. 2 is an enlarged cross-sectional view of a main part. In these figures, 1 indicates a core aligner. The core wire aligner 1 has two pairs of square rod-shaped arrays 2A and 2B. As shown in FIG. 2, each pair of array bodies 2A and 2B are held in parallel with each other with a space slightly larger than the outer diameter P of the core wire 10a, whereby core wire array grooves 3 and 3 are formed. ing. One end of each of the arrays 2A and 2B is fixed to a fixing plate 4 (see FIG. 1) with a fixing bolt or the like. One side surface of the depth adjusting nut 5 is fixed to substantially the center of the fixing plate 4, and a butterfly screw 6 is screwed into the depth adjusting nut 5. The butterfly screw 6 is screwed into the nut 5, penetrates through the fixing plate 4 in the thickness direction, and protrudes between the arrays 2A, 2A, 2B, 2B. One end of a coil spring 7 is fitted to the tip of the butterfly screw 6, and a pressing plate 8 is in contact with the other end of the coil spring 7. The pressing plate 8 is inserted into the core wire arranging groove 3 and both ends thereof are bent in a U shape to prevent the pressing plate 8 from coming out of the core wire arranging groove 3 in the arranging direction of the core wires 10a. The depth adjusting nut 5, the butterfly screw 6, the coil spring 7 and the pressing plate 8 constitute the elastic pressing means of the present invention.

A rectangular core wire chuck plate 11 is arranged between the arrays 2A and 2A and between the arrays 2B and 2B. As shown in FIG. 2, this core wire chuck plate 11 has a notch-shaped introduction hole 11a for introducing the core wire 10a at one end side, and a semicircular engagement hole 11b at the end of the introduction hole 11a. Has been formed. The insertion hole 11b is formed with a radius slightly larger than the outer diameter P of the core wire 10a so that the core wire 10a can be reliably inserted and held. At the other end of the core wire chuck plate 11, a rectangular core wire alignment plate 12 which is orthogonally inserted into the core wire array grooves 3 and 3 is fitted. The end surface of the core wire aligning plate 12 on the fitting side is located at the edge of the engagement hole 11b, and thereby presses the core wire 10a and always maintains the aligned state. One side of the core wire chuck plate 11 is fixed to the connecting member 13. The connecting member 13 is held by the moving mechanism 14. The moving mechanism 14 includes an air cylinder, etc., advances the core wire chuck plate 11 to insert it between the array bodies 2A, 2A and 2B, 2B, and inserts the core wire alignment plate 12 into the core wire array grooves 3, 3. To do. The movement mechanism 14 is controlled by the movement control unit 15. That is, the movement control unit 15 is composed of a computer and increases the protrusion amount of the air cylinder of the movement mechanism 14 by the outer diameter P of the core wire 10a every time the core wire 10a is taken out from the core wire arrangement grooves 3 and 3. The moving mechanism 14 is controlled as described above. That is, assuming that the chuck position of the core wire 10a to be taken out first is the starting point m and the number of the core wire 10a to be taken out is n, the movement control unit 15 calculates [m + (n-1) P] and moves. The mechanism 14 is controlled so that the amount of advancement of the core wire chuck plate 11 is set larger by the outer diameter P of the core wire 10a each time the core wire 10a is taken out.

By the way, the movement mechanism 14 causes the movement control unit 15 to retreat the core wire chuck plate 11 to a certain retreat position, as indicated by a chain line in FIG. Then, when the core wire chuck plate 11 is positioned at the retracted position, the conducting / arranging unit 16 is moved to this retracted position by the robot mechanism 17, and the core wire 10a is grasped and brought into conduction. This conduction signal is supplied to the control unit 18, and the control unit 18 calculates the array position of the core wires 10a based on the conduction signal, and controls the robot mechanism 17 based on the calculation result. Under this control, the robot mechanism 17 guides the conducting / arranging device 16 holding the core wire 10a to a predetermined arrangement position of an arrangement jig (not shown), releases the grasping of the conducting / arranging device 16 and releases the core wire 10a. Arrange a on the arrangement jig.

Next, the operation of the core wire supply device of the present invention will be described. First, a plurality of core wires 10a are exposed at the ends of the multi-core cable 10 shown in FIG. 1, and these core wires 10a are inserted into the core wire arranging grooves 3 and 3 and arranged in parallel. At the other end of the multi-core cable 10, a connector is attached to each core wire 10a.

Next, the butterfly screw 6 is turned to adjust the protrusion amount of the screw 6 via the depth adjusting nut 5. That is, the protrusion amount of the butterfly screw 6 is adjusted to press the core wire 10a located at one end (inner side) of the core wire array grooves 3 and 3 with the coil spring 7 and the pressing plate 8 and to be located at the other end. The core wire 10a is positioned at the starting point m.

On the other hand, the total number of core wires 10 a and the outer diameter P dimension thereof are input to the movement control unit 15. Then, the movement control unit 15 is operated to control the movement mechanism 14. That is, since the first core wire 10a to be taken out is the first core wire, n = 1, and the moving mechanism 14 advances the core wire chuck plate 11 to the starting point m position. Therefore, the core wire aligning plate 12 presses the core wires 10a and presses them against the other core wires 10a to align them in parallel, and these core wires 10a are pushed back by the elastic force of the coil spring 7, The first core wire 10a is securely inserted into the engagement hole 11b of the wire chuck plate 11. In this way, when the core wire 10a is engaged in the engagement hole 11b, the core wire chuck plate 11 is retracted to the retracted position, and as described above, the core wire 10a is passed through the conduction / arranger 16. The continuity is inspected and arranged on the arrangement jig.

Since n = 2 in the case of the second core wire 10a, the moving mechanism 14 advances the core wire chuck plate 11 to the starting point m + P position. Therefore, the core wire aligning plate 12 presses and aligns the second core wire 10a at the end portion, and the remaining core wire 10a is pushed back by the elastic force of the coil spring 7. The second core wire 10a is securely inserted into the engagement hole 11b. This second core wire 10a is also inspected for continuity and arranged in the arrangement jig.

In the case of the third and subsequent core wires, n = 3, n = 4, n = 5, ... The amount of forward movement is increased, and similarly, the core wire 10a of the third or less is securely inserted into the insertion hole 11b via the coil spring 7. Therefore, it is possible to reliably prevent chucking of the core wire 10a and to arrange the core wire 10a with good workability. Further, since the core wire 10a is inserted into the engagement hole 11b, the core wire 10a is not damaged. In the above embodiment, the amount of advancement of the core wire chuck plate 11 may be set to be slightly larger than the outer diameter P of the core wire 10a.

[Effect of the device]

 As described above, according to the present invention, every time the core wire is taken out of the core wire aligning groove of the core wire aligner, the core wire chuck means is moved forward by the movement control means by at least the outer diameter of the core wire. With this configuration, the core wire is pressed into the engagement hole of the core wire chuck means by the pressing force of the elastic pressing means and is securely inserted. Therefore, it is possible to provide a core wire supply device for an automatic array machine that can reliably hold the core wire without damaging it and supply it to the continuity inspection side.
