Incidentally, the first set 6 having a series of the first molding machine 11A, the second molding machine 11B, and the third molding machine 11C as the plurality of molding machines, and the second set 7 having a series of the first molding machine 11A, the second molding machine 11B, and the third molding machine 11C as the plurality of molding machines make the first standard electric wire 33A on which the wiring clips 35 are integrally molded, the second standard electric wire 33B on which the wiring clips 35A are integrally melded, and the third standard electric wire 33C on which the wiring clips 35B in synchronization with manufacturing timing of the above-described harness manufacturing line 2.
The standard harness 31A formed in this way is wired on the wiring board 63a corresponding to the initial position in the conveying direction (an arrow “a” direction) by the above-described device 1 for manufacturing a wiring harness 51, and the wiring harness 51 is manufactured by the above-described manufacturing method.
As explained above, in the method for manufacturing a wiring harness 51 according to the second embodiment of the present invention, the standard harness 31 is made by integrally molding the wiring clips 35, 35A, 35B as the plurality of exterior components with the first standard electric wire 33A, the second standard electric wire 33B, and the third standard electric wire 33C as the plurality of standard electric wire by the first molding machine 11A, the second molding machine 11B, and the third molding machine 11C as the plurality of molding machines, and by bundling the first standard electric wire 33A, the second standard electric wire 33B, and the third standard electric wire 33C. Therefore, the plurality of wiring clips 35, 35A, 35B can be integrally molded by a series of the first molding machine 11A, the second molding machine 11B, and the third molding machine 11C. Further, the wiring clips 35, 35A, 35B can be integrally molded with the respective first standard electric wire 33A, the second standard electric wire 33B, and the third standard electric wire 33C by the respective first molding machine 11A, the second molding machine 11B, and the third molding machine 11C. Thereby, the first molding machine 11A, the second molding machine 11B, and the third molding machine 11C are independent from each other. Namely, influences of progresses of the other molding machines received by each of the molding machines 11A, 11B, 11C can be reduced, and productive efficiency can be improved.
Incidentally, in the embodiments of the present invention, the harness manufacturing line 2 in which the wiring board 63 is rotated in the conveying direction is explained. However, for example, the wiring board 63 may be moved straight from one side to the other side.
Further, various molded products such as fixture components of clamp, clip or the like, plug cap, waterproof plug, or grommet may be integrally molded with the standard electric wire 33 (33A, 33B, 33C) by the molding machine 11 instead of the wiring clip 35 (35A, 35B) as the exterior component to form the standard harness 31 (31A).
Further, the types of the plurality of wiring clips 35, 35A, 35B may be the same, or may be two types in which the wiring clip 35 and the wiring clip 35B are the same other than that all of the wiring clips 35, 35A, 35B are different from each other according to the embodiments.
Further, because the wiring clips 35, 35A, 35B are formed in a shape suitable for their use, they are not limited to the shapes shown, and well-known shapes of the wiring clips can be used.
Further, a plurality of clip cavities 16c provided on the molding die 15 (15A, 15B) is provided corresponding to shapes depending on use of the molded wiring clip 35 (35A, 35B). Therefore, the shapes (types) of the clip cavities 16c may be the same or may be different from each other.
Further, other than the above embodiments in which the wiring harness 51 is manufactured in a synchronization manner by synchronizing the harness manufacturing line 2 as a main line to the molding line 3 as a line side, the wiring harness 51 can be manufactured in a synchronization manner with the main line being the harness manufacturing line 2 and the line side being a molding device (or a molding process) in which components are integrally molded with the molded components.
In such a case, in the molding device (or the molding process), fixing components such as a clip, a clamp, a waterproof plug, and a plug cap are integrally molded (so-called two-color molding) with the previously molded components such as a protector and a corrugate tube to manufacture secondary molded components. Then, the secondary molded components are assembled with the sub harness 41, the main harness 53, and the like in synchronization with the harness manufacturing line 2 as the main line to manufacture the wiring harness 51.
Incidentally, the exterior components such as a protector and a corrugate tube may be integrally molded with the standard electric wire 33 previously, and further, the locking portion 39 and the like may be integrally molded (so-called two-color molding) with the exterior components.
In this way, because the secondary molded components mounted on the wiring harness 51 are manufactured in synchronization with the harness manufacturing line 2, the secondary molded components can be supplied without excess or deficiency, and it becomes unnecessary to store many secondary molded components as a stock.
Further, electronic products can be manufactured in a synchronization manner with the main line as the manufacturing line and the line side as the molding device (or molding process) for further integrally molding components with the molded components.
In such a case, in the molding device (or molding process) as the line side, for example, fixing components such as a clip and a clamp, a watertight plug, and a plug cap are integrally molded (so-called two-color molding) with the previously molded components such as a housing of an electronic unit, a housing of an electrical junction box, or a housing of a meter to manufacture secondary molded components. Then, the secondary molded components are assembled to the predetermined positions in synchronization with the manufacturing line to manufacture electronic products such as the electronic unit, the electrical junction box, and the meter.
In this way, because the housings of such as the electronic products are manufactured in synchronization with the manufacturing line, the housings can be supplied without excess or deficiency, and it becomes unnecessary to store a lot of housings as a stock.
Further, vehicle body components, electronic products and the like can be manufactured in a synchronization manner with the main line as the vehicle manufacturing line and the line side as the molding device (or molding process) for further integrally molding components with the molded components.
In such a case, in the molding device (or molding process) as the line side, for example, fixing components such as a clip and a clamp, a watertight plug, and a plug cap are integrally molded (so-called two-color molding) with the previously molded components such as a bumper, a door trim, an instrument panel and the other vehicle body components, or the previously molded components such as a housing of an electronic unit, a housing of an electrical junction box, or a housing of a meter to manufacture secondary molded components. Then, the secondary molded components are assembled to the predetermined positions in synchronization with the vehicle manufacturing line to manufacture a vehicle, and the electronic products such as the electronic unit, the electrical junction box, and the meter mounted on the vehicle.
In this way, because the vehicle body components and the housings of such as the electronic products are manufactured in synchronization with the vehicle manufacturing line, it becomes unnecessary to store many vehicle body components composing a vehicle, and a lot of housings of the electronic products mounted on a vehicle as a stock in the vehicle manufacturing line.
