Description

Electric wire production system

 The present invention relates to an electric wire production system for producing an electric wire used for a wire harness or the like that is routed to an automobile or the like as a moving body.

BACKGROUND ART Yarn 1

 Electric wires are produced by continuously coating the outer periphery of a core wire composed of a plurality of strands with synthetic resin, and the longer the length, the better the productivity is. In many cases, the production is usually performed with minimal color change. Therefore it is common to produce long strips of the same color. Many large-size long products are also used for packaging. For example, in the warehouses of electric wire sales companies, wires are often cut and sold according to customer requirements. In particular, wire harnesses for electric circuits with many color combinations are used in automobiles, home appliances, aircraft, and electric machines.

 Various electronic devices are mounted on automobiles and the like as moving bodies. For this reason, the above-mentioned automobiles and the like are provided with a wire harness in order to transmit power from a power source or the like to control signals from a computer or the like to the electronic device. The wire harness includes the above-described plurality of electric wires, a connector attached to an end of the electric wires, and the like.

 The electric wire includes a conductive core wire and an insulating coating covering the core wire. The electric wire is a so-called covered electric wire. The connector includes a terminal fitting and an insulating connector housing. The terminal fitting is made of a conductive sheet metal or the like. The connector housing is formed in a box shape and houses the terminal fitting. The wire harness transmits the power and signals required for the electronic devices described above, such as when the connectors are connected to the connectors of the electronic device.

For the wires of the above-mentioned wire harness, it is necessary to identify the size of the core wire, the material of the sheath (change of material due to heat resistance, etc.), and the purpose of use. The purpose of use includes, for example, airbags, ABS (Antilock Brake System) and vehicle speed information. It shows control signals such as information and vehicle guns (systems) that use electric wires such as power transmission systems.

 The wires of the wire harness were colored in various colors to identify the purpose of use (system) described above. In the production of conventional electric wires, when an insulating synthetic resin is extruded and coated on the outer periphery of a core wire, a colorant of a desired color is mixed into the synthetic resin to obtain a desired color. .

 For this reason, the wire factory manufactures wires of all colors required by the ordering side for each color, cuts them into predetermined lengths, for example, 500 to 200 Om, Were bundled, for example. In order to deliver necessary wires to the ordering side after receiving an order, first, according to the order from the ordering side, bundles of wires of the required color are wrapped in a number that satisfies the order quantity and distributed from the wire plant. It is transported to a base. At the distribution base, the bundled wires were cut to the required length and delivered to the ordering side. Alternatively, a number of bundles satisfying the order volume were delivered from the distribution base to the ordering side. In the above-described conventional method for producing electric wires, in an electric wire factory, for example, the electric wires are cut every 500 to 200 m, and the electric wires are bundled. In addition, wire plants produce wires of various colors that the ordering party may need. In addition, distribution bases have cut bundled wires into lengths according to the order quantity from the ordering side. Or, a number of bundles satisfying the order quantity were delivered from the distribution base to the ordering side.

 When a number of bundles satisfying the order quantity are delivered from the distribution base to the ordering side, the ordering side purchases more wires than necessary. For this reason, if the ordering side manufactures a product using the electric wire such as the above-mentioned wire harness, the cost of the product may be increased. Also, if the bundled wires are cut and delivered at the logistics base to a length corresponding to the order quantity from the ordering side, extra wires are generated after delivery at the logistics base, and more There is a possibility that electric wires are generated for each color.

 As described above, in the above-described conventional order-made production method of electric wires, at least one of the distribution base and the ordering side has more electric wires than necessary, which is not desirable from the viewpoint of resource saving.

Further, the wire factory manufactures wires for each color. For this reason, at the above-mentioned wire plant and logistics base, a very large space is required to store wires. Had to keep. For this reason, the production efficiency of the wire harness may be reduced, and the cost of a product using an electric wire such as the wire harness may increase. Furthermore, the electric wire is colored by mixing a coloring agent into the synthetic resin constituting the covering portion. For this reason, it is not easy to change the color of the wire on the wire manufacturing line. For this reason, wire manufacturing lines often manufacture wires in advance without waiting for orders from the ordering side. This was also undesirable from the viewpoint of resource saving and caused the cost of electric wires to rise.

 Accordingly, an object of the present invention is to provide an electric wire production system capable of suppressing an increase in cost of a product using an electric wire such as a wire harness and saving resources. Disclosure of the invention

The first production amount data creation module 14 sends the first production amount data DT 1 to the manufacturing section 11 via the output module 19.

 The second production amount data creation module 15 decodes the production amount data DT based on a program stored in the database 17. The second production amount data creation module 15 calculates the product number of the electric wire 3 to be produced, the shape of the mark 8 and the length of each of the colors B and R of the mark 8 from the production amount data DT, Create production data DT2. The second production amount data DT2 indicates the product number of the electric wire 3 to be produced, the shape of the mark 8, and the length of each of the colors B and R of the mark 8. The second production amount data creation module 15 sends the second production amount data DT 2 to the coloring cutting section 12 via the output module 19.

 As the production unit 11, for example, an electric wire production line of an electric wire factory is used. As shown in FIG. 5, the manufacturing unit 11 includes a supply unit 20, an extruded covering unit 21, a cooling water tank 22, and a winding unit 23. When manufacturing the electric wire 3, the manufacturing unit 11 moves (moves) the core wire 4 or the electric wire 3 to the supply unit 20, the extruded coating unit 21, the cooling water tank 22 and the winding unit 23 in order. . In order to move (move) the core wire 4 or the electric wire 3, the manufacturing unit 11 includes a plurality of burries 24.

The supply unit 20 supplies the core wire 4 in a state where the covering portion 5 is not covered. The extruded coating unit 21 extrudes and coats an insulating synthetic resin around the core wire 4 supplied from the supply unit 20 to form a coating portion 5. The cooling water tank 22 cools the sheath 5 covered with the core wire 4 by the extrusion sheath 21. The winding unit 23 cuts the electric wire 3 composed of the core wire 4 and the covering portion 5 covering the core wire 4 at intervals of, for example, 500 m to 200 m, and winds the wire 3 on a drum or the like. Thus, when the first production amount data DT1 is input, the manufacturing unit 11 transmits the electric wire 3 of a single color P such that the outer surface 5a is white, for example, based on the first production amount data DT1. The required length is manufactured for each part number. Therefore, the outer surface 5 _a of the electric wire 3 manufactured unit 1 1 is manufactured, at least the same size are the same color. It is desirable that the outer surface 5a of all the wires 3 manufactured by the manufacturing unit 11 be the same color. Further, when the first production amount data DT1 is input, the production unit 11 creates first confirmation data .DK1. The manufacturing section 11 sends the created first confirmation data DK1 to the data integration module 13 via the input module 18 and also sends it to the color cutting section 12. The manufacturing unit 11 conveys the electric wire 3 manufactured based on the first production amount data DT1 to the colored cutting unit 12. Thus, the manufacturing unit 11 manufactures the electric wire 3 of a single color P having a product number and a length corresponding to the first production amount data DT 1, and conveys it to the colored cutting unit 12. When the first production data DT 1 is sent from the production control unit 10, the manufacturing unit 11 sends the electric wires 3 in an amount corresponding to the first production data DT 1 to the colored cutting unit 12. The first confirmation data DK1 indicating the date when the sheet can be conveyed is sent to both the production control unit 10 and the coloring / cutting unit 12.

 Further, the manufacturing unit 11 may manufacture the uncolored electric wire 3 as the single color P. The term “non-colored” in this specification refers to a state in which various kinds of coloring materials are not mixed in the synthetic resin constituting the covering portion 5 of the electric wire 3, and refers to the above-described color of the synthetic resin itself. For this reason, uncolored is an example of a single color P.

As the colored cutting section 12, for example, a wire harness assembly line of a wire harness factory is used. When the second production amount data DT 2 is input and the single-color P electric wire 3 is conveyed from the manufacturing unit 11, the coloring and cutting unit 12 outputs the electric wire 3 based on the second production amount data DT 2. For each part number, mark 8 of desired shape with desired colors B and R (partially colored) and cut to desired length. When the second production amount data DT1 is input and the first confirmation data DK1 is input from the manufacturing unit 11, the coloring cutting unit 12 creates the second confirmation data DK2. The coloring / cutting unit 12 sends the created second confirmation data DK2 to the data integration module 13 via the input module 18. Thus, the colored cutting section 12 colors the outer surface 5a of the electric wire 3 of the single color P with desired colors B and R according to the second production data DT2, and puts the mark 8 on the outer surface 5a. Form and cut to desired length. When the second production amount data DT2 is sent from the production control unit 10 and the first confirmation data DK1 is sent from the production unit 11, the coloring and cutting unit 12 responds to the second production amount data DT2. Then, the second confirmation data DK 2 indicating the date on which the colored and cut wire 3 is obtained is sent to the production control unit 10. As shown in FIG. 6, the colored cutting section 12 includes an electric wire cutting device 25 and an electric wire coloring device 26. As shown in FIG. 6, the electric wire cutting device 25 includes a main body 27 installed on a floor of a factory or the like, a measuring mechanism 28, and a cutting mechanism 29. The main body 27 is formed in a box shape. The measuring mechanism 28 includes a pair of belt feed units 30. The belt feed unit 30 includes a drive pulley 31 rotated by a motor or the like, a plurality of driven pulleys 32, and an endless belt 33 wound around the pulleys 31 and 32. Endless belt 33 rotates around pulleys 31 and 32.

 The pair of belt feed units 30 sandwiches the electric wire 3 between each other, and rotates the endless belt 33 by rotating the drive pulley 31 in synchronization, thereby feeding the electric wire 3 by a predetermined length. At this time, the pair of belt feed units 30 move the electric wire 3 along the arrow K in FIG. 1 parallel to the longitudinal direction of the electric wire 3. .

 The cutting mechanism 29 is arranged on the downstream side of the arrow K of the pair of belt feed units 30. The cutting mechanism 29 includes a pair of cutting blades 34, 35. The pair of cutting blades 34, 35 are arranged in a vertical direction. The pair of cutting blades 34, 35 approach and move away from each other along the vertical direction. When the 'pair of cutting blades 3' 4 and 35 approach each other, they cut the electric wire 3 sent out by the pair of belt feed units 30 between them. When the pair of cutting blades 34 and 35 are separated from each other, they are, of course, separated from the electric wire 3.

 The electric wire cutting device 25 having the above-described configuration includes an electric wire 3 between a pair of belt feed units 30 with the pair of cutting blades 34 and 35 of the cutting mechanism 29 separated from each other. Out along arrow K. After sending out the electric wire 3 of a predetermined length, the drive pulleys 31 of the pair of belt feed units 30 stop. Then, the pair of cutting blades 34 and 35 approach each other, and cut the wire 3 between the cutting blades 34 and 35.

The wire coloring device 26 is a device for forming the mark 8 having the above-described configuration on the outer surface 5 a of the wire 3. As shown in FIG. 7, the electric wire coloring device 26 includes a plurality of coloring units 36, an encoder 37 as detection means, and a control device 38. In the illustrated example, a pair of coloring units 36 is provided. The plurality of coloring units 3 6 They are arranged along arrow K.

 As shown in FIG. 6, the plurality of coloring units 36 are provided between a pair of belt feed units 30 of a measuring mechanism 28 and a pair of cutting blades 34, 35 of a cutting mechanism 29. Are arranged. Each coloring unit 36 includes a nozzle 39 and a valve 40. nozzle

39 is opposite to the electric wire 3 moved along the arrow に よ っ て by a pair of belt feed units 30. In the nozzle 39 of one coloring unit 36, the coloring material of the first color Β described above is supplied from a coloring material supply source 41 (shown in FIG. 7), and the other coloring unit 36 The colorant of the second color R described above is supplied into the nozzle 39 from a colorant supply source 41 (shown in FIG. 7).

 Valve 40 is connected to nozzle 39. Further, the valve 40 is further connected to a pressurized gas supply source 42 (shown in FIG. 7). The pressurized gas supply source 42 supplies the pressurized gas to the nozzle 39 via the valve 40. When valve 40 opens, pressurized gas supply

Due to the pressurized gas supplied from 42, the coloring material in the nozzle 39 jets (drops) toward the outer surface 5a of the electric wire 3.

 When the valve 40 closes, the colorant in the nozzle 39 stops flowing. With the above-described configuration, the coloring unit 36 opens the valve 40 for a predetermined time in response to a signal from the control device 38 or the like, and jets a certain amount of the coloring material toward the outer surface 5a of the electric wire 3. (Drip). .

 The above-mentioned coloring material is a liquid material in which a coloring material (organic organic material) is dissolved and dispersed in water or another solvent. Organic substances include dyes and pigments (mostly organic substances and synthetic products). Sometimes, dyes are used as pigments and pigments are used as dyes. As a more specific example, the coloring material is a coloring liquid or a paint. The term “colored liquid” refers to a substance in which a dye is dissolved or dispersed in a solvent, and the term “paint” refers to a substance in which a pigment is dispersed in a dispersion. Therefore, when the coloring liquid adheres to the outer surface 5a of the electric wire 3, the dye penetrates into the coating portion 5, and when the paint adheres to the outer surface 5a of the electric wire 3, the pigment soaks into the coating portion 5. Without outer surface

5 Adhere to a. That is, the coloring unit 36 dyes a part of the outer surface 5a of the electric wire 3 with a dye or paints the outer surface 5a of the electric wire 3 with a pigment. For this reason, marking the outer surface 5a of the electric wire 3 means that a part of the outer surface 5a of the electric wire 3 is dyed (dyed). And that the pigment is applied to a part of the outer surface 5a of the electric wire 3.

 Further, it is desirable that the solvent and the dispersion have an affinity with the synthetic resin constituting the coating portion 5. In this case, the dye will surely penetrate into the coating portion 5, and the pigment will surely adhere to the outer surface 5a.

 In addition, the term “drip” refers to the ejection of a liquid coloring material from the nozzle 39 of the coloring hut 36 in the state of a droplet, that is, in the state of a droplet, by being urged toward the outer surface 5 a of the fixed amount of electric wire 3. It will be issued. For this reason, the nozzle 39 of the coloring unit 36 of the power / coloring device 26 of the present embodiment uses the liquid coloring material to convert the liquid Bias toward the outer surface 5a.

 The encoder 37 measures information based on the moving amount and the moving speed of the electric wire 3 and outputs the information to the control device 38. The control device 38 is a computer equipped with a well-known RAM, ROM, CPU, and the like. The control device 38 is connected to the encoder 37 and the valve 40 to control the entire electric wire coloring device 26.

 The control device 38 has a distance D 1, D 2, D 3 between the marks 8 formed on the outer surface 5 a of the electric wire 3 and the diameters R 1, R 2 of the points 6 and 7 and the number of the points 6 and 7. I remember. The control device 38 'stores many types of the shapes of the marks 8 described above. That is, the control device 38 stores the shapes of the marks 8 of a plurality of patterns. The control device 38 stores the interval between the nozzles 39 of the coloring unit 36. The above-described second production amount data D T2 and the like are input to the control device 38. Based on the input second production amount data DT 2, the speed information of the electric wire 3 from the encoder 37, the interval between the nozzles 39, etc., the control device 38 controls each valve 40 and the pressurized gas supply source. Control 4 2 etc. The control device 38 controls each valve 40 and the pressurized gas supply source so that the mark 8 is formed on the outer surface 5a of the electric wire 3 with a pattern that satisfies the second production data DT2. Control 4 2 etc.

When the electric wire coloring device 26 having the above-described configuration marks the outer surface 5a of the electric wire 3 immediately after forming the mark 8 on the outer surface 5a of the electric wire 3, a pair of belts of the electric wire cutting device 25 are used. Feed unit 30 moves wire 3 along arrow K. Then, the control device 38 controls the valve 40 and the like, and jets a fixed amount of liquid coloring material from the nozzle 39 of each coloring unit 36 toward the outer surface 5a of the electric wire 3 (droplet spraying). I do. The control device 3 8 marks the outer surface 5 a of the electric wire 3 in a pattern that satisfies the second production data DT 2 8 To form '' In this way, the colored cut section 1 2 paints the outer surface 5 a of the covering section 5 of the electric wire 3 or dyes the outer surface 5 a of the covering section 5 with a coloring liquid, thereby forming the outer surface of the electric wire 3. 5 Mark a in a predetermined pattern (form a color mark 8 in a desired shape). Further, the colored cutting section 12 cuts the electric wire 3 marked with a desired pattern into a desired length.

 When manufacturing the electric wire 3 using the electric wire production system 1, first, in step S1 in FIG. 3, it is determined whether or not the input unit 9 has an input. If there is no input in the input section 9, step S1 is repeated, and if there is an input, the flow proceeds to step S2.

 In step S2, the electric wire production data D is sent from the personal computer 9a of the input unit 9 to the personal computer 10a of the production control unit 10. Then, the computer 10a of the production control unit 10 sends the first production amount data DT1 to the production unit 11 and also sends the second production amount data DT2 to the coloring and cutting unit 12. .

 Then, the first confirmation data DK1 of the production unit 11 is sent to both the personal computer 10a of the production control unit 10 and the coloring and cutting unit 12. The coloring / cutting unit 12 sends the second confirmation data DK2 to the personal computer 10a of the production control unit 10. The production control unit 10 sends the second confirmation data D K2 to the input unit 9. Then, the manufacturing unit 11 manufactures the electric wire 3 of the single color P to a length that satisfies the first production data D T 1 for each product number, and proceeds to step S3.

 In step S3, the electric wire 3 of the single color P manufactured by the manufacturing unit 11 is transported to the colored cutting unit 12. In the colored cutting section 12, based on the second production amount data DT 2, the colored unit 36 emits the coloring material toward the outer surface 5 a of the electric wire 3 (droplet spraying). The outer surface 5a of the electric wire 3 is marked with this pattern, cut to a desired length, and the process proceeds to step S4. In step S4, the appearance inspection of the electric wire 3 is performed in the colored cut section 12.

According to the present embodiment, based on the electric wire production amount data D to the input unit 9, the production control unit 10 generates the first production amount data DT1 indicating the product number and length of the electric wire 3 to be produced. 1 and the number indicating the product number and length of wire 3, the shape of mark 8, and the color of mark 8. 2 Production data DT 2 is sent to the colored cutting section 12. The manufacturing unit 11 manufactures a required amount of the electric wire 3 of the single color P and transports it to the colored cutting unit 12. For this reason, the quantity (strip length) of the electric wire 3 stored in advance in the manufacturing unit 11 can be suppressed. In addition, the manufacturing section 11 manufactures the electric wire 3 of the single color P. For this reason, the type (color type) of the wire 3 stored in advance in the manufacturing unit 11 can be suppressed, and there is no need to manufacture the wire 3 in advance. Then, the desired mark 8 is colored with the desired color B or R on the outer surface 5a of the electric wire 3 of the single color P at the colored cutting section 12 and cut to a desired length. For this reason, the amount of the electric wire 3 temporarily stored between the manufacturing section 11 and the colored cutting section 12 can be suppressed.

 For this reason, the space required for storing the electric wires 3 in advance can be suppressed, and the space required for temporarily storing the electric wires 3 during manufacturing can be suppressed. Therefore, it is possible to suppress an increase in the cost of the electric wire 3 itself and a product such as a wire harness using the electric wire 3. Also, the required length of the monochromatic P electric wire 3 is manufactured, and the outer surface 5a of the monochromatic P electric wire 3 is colored and cut to a desired length. For this reason, no extra wires 3 are generated between the time the wires 3 are manufactured and the time they are delivered. Therefore, useless electric wires 3 can be prevented from being generated, and resources can be saved.

 Also, by inputting wire production data D indicating the required product number, length, color, shape of the mark, etc. of the wire 3 into the input unit 9, the manufacturing unit 11 produces the wire 3 and the colored cutting unit 1 2 coloring 'cutting'. Therefore, when the electric wire production data D is input to the input unit 9, the desired electric wire 3 is promptly produced. Therefore, the time from ordering the electric wire 3 to finishing the production can be shortened. For this reason, there is no need to predict the consumption in advance and manufacture the wire 3 in advance. Therefore, it is possible to reliably prevent the extra stock of the electric wire 3 from being generated, and to suppress a high darning of the cost of the electric wire 3 and a product such as a wire harness using the electric wire 3.

 When the electric wire 3 manufactured by the manufacturing unit 11 is non-colored, the electric wire 3 can be surely colored to a desired color as required.

The coloring section 12 includes a plurality of coloring units 36. Each of the coloring units 36 jets a fixed amount of a liquid coloring material toward the outer surface 5a of the electric wire 3 (drops). Shooting). The color of the coloring material ejected (dropped) from the plurality of coloring units 36 is different. For this reason, the color for coloring the outer surface 5a of the electric wire 3 can be easily switched by switching the coloring unit 36 for ejecting (dropping) the coloring material. Accordingly, the outer surface 5a of the wire 3 can be easily colored with a desired color, and a portion where the coloring material before switching the coloring material and the coloring material after switching can be suppressed, and the yield of the wire 3 can be reduced. Can be prevented from decreasing.

 Further, the coloring unit 36 jets (drops) a predetermined amount of a liquid coloring material toward the outer surface 5 a of the electric wire 3. For this reason, the shape of the mark 8 formed on the outer surface 5a of the electric wire 3 can be easily changed by changing the amount of the colorant emitted from the coloring unit 36 and the ejection interval. Therefore, the outer surface 5a of the electric wire 3 can be colored to a desired color without wasting the coloring material, and a rise in the cost of the electric wire 3 and a wire harness using the electric wire 3 can be suppressed.

 Manufacturing unit 1 1 Power Sends the first confirmation data DK 1 that enables the transfer of the electric wire 3 of the single color P to the production control unit 10 and the colored cutting unit 12. The colored cutting section 12 sends the production control section 10 second confirmation data DK 2 indicating the date on which the colored and cut electric wire 3 is obtained according to the second production amount data D T 2. For this reason, the production control unit 10 can grasp the progress of the manufacturing process of the electric wire 3. In the colored cut section 12, the date when the electric wire 3 of the single color P is conveyed can be confirmed.

 After receiving the order for the electric wire 3, the electric wire 3 of the single color P is manufactured to the required length. For this reason, the quantity (length) of the electric wires 3 stored in advance can be suppressed. In addition, a single color P electric wire 3 is used. For this reason, the type (color type) of the electric wire 3 stored in advance can be suppressed.

 The required length of the monochromatic P electric wire 3 is manufactured, and the outer surface 5a of the monochromatic P electric wire 3 is colored and cut to a desired length. Therefore, there is no need to store the electric wire 3 in addition to the space between the manufacturing section 11 and the colored cutting section 12. Therefore, it is possible to suppress the amount of the wire 3 to be stored between receiving the order and delivering the wire 3.

For this reason, the space required for storing the electric wires 3 in advance can be reduced, and the space required for storing the electric wires 3 during manufacturing can be suppressed. Therefore, it is possible to suppress a rise in the cost of the electric wire 3 itself and the cost of a product using the electric wire 3. In addition, the required length of the monochromatic P electric wire 3 is manufactured, and the outer surface 5 a of the monochromatic P electric wire 3 is colored. In order to cut to the desired length, no extra wires 3 are generated between receiving the order for the wires 3 and finishing the production. Therefore, useless electric wires 3 can be prevented from being generated, and resources can be saved.

 Next, an electric wire production system 1 according to a second embodiment of the present invention will be described with reference to FIG. 8 or FIG. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

 In the present embodiment, the electric wire production system 1 includes a colored section 12a instead of the colored cut section 12 as shown in FIGS. Other configurations of the electric wire production system 1 are the same as those of the above-described first embodiment. As shown in FIGS. 11 and 12, the colored portion 12a does not include a cutting mechanism 29, that is, a pair of cutting blades 34, 3.5. Other configurations of the colored section 12a are the same as those of the colored cut section 12 of the first embodiment described above.

 The colored portion 12 a is configured to color the outer surface 5 a of the electric wire 3 having the single color P, which is manufactured by the manufacturing portion 11, with a desired mark 8 to a desired color B or R. According to the second production amount data DT2 sent from the production control unit 10, the coloring unit 12a changes the outer surface 5a of the electric wire 3 of the single color P to a desired color B or R. By coloring, a desired mark 8 is formed on the outer surface 5a.

 The coloring section 12a includes a plurality of coloring units 36 for jetting (dropping) a predetermined amount of a liquid coloring material toward the outer surface 5a of the electric wire 3. The colors of the coloring materials ejected (dropped) by the plurality of coloring units 36 are different from each other, and each of the plurality of coloring units 36 is in liquid coloring in accordance with the second production amount data DT2. The material is ejected (drip) toward the outer surface 5a of the electric wire 3.

Further, the coloring section 12a has a first date indicating the date when the electric wire 3 in an amount corresponding to the first production amount data DT1 can be transferred from the manufacturing section 11 to the coloring section 12a. Confirmation data DK 1 will be sent. When the second production amount data DT2 is sent from the production control unit 10 and the first confirmation data DK1 is sent from the production unit 11, the coloring unit 12a According to the second production data DT2, the second confirmation data DK2 indicating the date when the colored electric wire 3 is obtained is sent to the production control unit 10. When manufacturing the electric wire 3 using the electric wire production system 1 of the present embodiment, first, in step S1 in FIG. 10, it is determined whether or not the input unit 9 has an input. If there is no input in the input section 9, step S1 is repeated, and if there is an input, the process proceeds to step S2.

 In step S2, the electric wire production data D is sent from the personal computer 9a of the input unit 9 to the personal computer 10a of the production control unit 10. Then, the computer 10a of the production control unit 10 sends the first production amount data DT1 to the production unit 11 and the second production amount data DT2 to the coloring unit 12a. ,.

 Then, the manufacturing unit 11 sends the first confirmation data DK1 to both the personal computer 10a of the production control unit 10 and the coloring unit 12a. The coloring section 12a sends the second confirmation data DK2 to the personal computer 10a of the production control section 10. The production control unit 10 sends the second confirmation data DK2 to the input unit 9. Then, the manufacturing unit 11 manufactures the single-color P electric wire 3 in a length satisfying the first production data DT1 for each product number, and proceeds to step S3a.

 In step S3a, the single color P electric wire 3 manufactured by the manufacturing unit 11 is transported to the coloring unit 12a. According to the second production data DT2, the coloring unit 12a causes the coloring unit 36 to discharge (drip) a liquid coloring material toward the outer surface 5a of the electric wire 3 to obtain a desired color. Mark the outer surface 5a of the electric wire 3 with the pattern shown in FIG. In step S4, the appearance inspection of the electric wire 3 is performed in the colored portion 12a.

 According to the present embodiment, as in the first embodiment described above, the number (length) of the electric wires 3 stored in advance in the manufacturing unit 11 can be suppressed. In addition, the types (color types) of the electric wires 3 that are stored in advance in the manufacturing unit 11 can be suppressed, and there is no need to manufacture the electric wires 3 in advance. Furthermore, the amount of the electric wire 3 temporarily stored between the manufacturing section 11 and the colored cutting section 12 can be suppressed.

For this reason, the space required for storing the electric wires 3 in advance can be suppressed, and the space required for storing the electric wires 3 during manufacturing can be suppressed. Therefore, it is possible to suppress a rise in the cost of the electric wire 3 itself and a product such as a wire harness using the electric wire 3. Also, the required length of the monochromatic P electric wire 3 is manufactured, and the outer surface 5a of the monochromatic P electric wire 3 is colored and cut to a desired length. For this reason, we manufacture wire 3 No extra wires 3 are generated between the delivery and delivery. Therefore, useless electric wires 3 can be prevented from being generated, and resources can be saved.

 In addition, by inputting the wire production data D indicating the required product number, length, color, shape of the mark, etc. of the wire 3 into the input section 9, the manufacturing section 1 1 produces the wire 3 and the coloring section 1 2 a is colored. Therefore, when the electric wire production data D is input to the input unit 9, the desired electric wire 3 is promptly produced. Therefore, the time from ordering the electric wire 3 to finishing the production can be shortened. Therefore, there is no need to predict the consumption in advance and manufacture the wire 3 in advance. Therefore, it is possible to reliably prevent an extra stock of the electric wire 3 from occurring, and to suppress a rise in the cost of the electric wire 3 and a product such as a wire harness using the electric wire 3.

 When the electric wire 3 manufactured by the manufacturing unit 11 is non-colored, the electric wire 3 can be surely colored to a desired color as required.

 The coloring section 1 2 a includes a plurality of coloring units 36. Each of the coloring cuts 36 jets (drops) a predetermined amount of a liquid coloring material toward the outer surface 5 a of the electric wire 3. The color of the coloring material ejected (dropped) from the plurality of coloring units 36 is different. For this reason, the color for coloring the outer surface 5a of the electric wire 3 can be easily switched by switching the coloring unit 36 that ejects (drops) the coloring material. Accordingly, the outer surface 5a of the electric wire 3 can be easily colored with a desired color, and a portion where the coloring material before switching the coloring material and the coloring material after switching can be suppressed, and the yield of the electric wire 3 can be reduced. Can be prevented from decreasing.

 Further, the coloring unit 36 jets (drops) a predetermined amount of a liquid coloring material toward the outer surface 5 a of the electric wire 3. Therefore, the shape of the mark 8 formed on the outer surface 5a of the electric wire 3 can be easily changed by changing the amount of protrusion of the coloring material and the distance between the protrusions of the coloring unit 36. Therefore, the outer surface 5a of the electric wire 3 can be colored to a desired color without wasting the coloring material, and a rise in the cost of the electric wire 3 and the wire harness using the electric wire 3 can be suppressed.

The manufacturing unit 11 sends the first confirmation data Dl enabling the transfer of the monochrome P wire 3 to the production control unit 10 and the coloring unit 12a. The second confirmation data DK 2 indicating the date when the colored and cut electric wire 3 can be obtained according to the second production data DT 2 is colored 1 2a sends to the production control unit 10; Therefore, the production control unit 10 can grasp the progress of the manufacturing process of the electric wire 3. In the colored section 12a, the date when the electric wire 3 of the single color P is carried can be checked.

 In the above-described embodiment, the manufacturing unit 11 and the colored cutting unit 12 are separate bodies. However, in the present invention, as shown in FIG. 13, the colored cutting section 12 having the above-described configuration may be incorporated in the manufacturing section 11. In this case, it is desirable to remove the cooling water tank 22 and the like, and to arrange the colored cut portion 12 between the extruded coating unit 21 and the winding unit 23. In the case shown in Fig. 13, the space required for installation of the electric wire production line can be reduced. In the case shown in FIG. 13, it goes without saying that the colored cut portion 12a may be replaced with the colored portion 12a.

And the second production data indicating the wire part number, length, and the shape and color of the mark are sent to the colored cutting section. The production department produces the required amount of solid-colored wire. And transport it to the colored cutting section. Since the manufacturing department manufactures monochromatic electric wires, the quantity (strip length) of electric wires stored in advance by the manufacturing department can be suppressed. In addition, the manufacturing department manufactures monochromatic electric wires. For this reason, it is possible to suppress the types (color types) of electric wires stored in advance in the manufacturing department, and it is not necessary to manufacture the electric wires in advance.

 The manufacturing section manufactures the required length of a single-color electric wire, and the colored cutting section colors the outer surface of the single-color electric wire to a desired color, forms a desired mark, and cuts the desired length. For this reason, the amount of electric wire once stored between the manufacturing section and the colored cutting section can be suppressed.

 For this reason, the space required for storing the electric wires in advance can be suppressed, and the space required for storing the electric wires during manufacturing can be suppressed. Therefore, it is possible to suppress a rise in the cost of the electric wire itself and the cost of a product using the electric wire. In addition, monochromatic wires are manufactured to the required length, the outer surface of the monochromatic wires is colored, cut to the desired length, and delivered to the ordering side. Therefore, no extra wires are generated between the time the wires are manufactured and delivered. Therefore, useless electric wires can be prevented from being generated, and resources can be saved.

 In addition, by inputting the wire production data indicating the required wire part number, length, shape and color of the mark, etc. into the input unit, the manufacturing department produces the wire and the colored cutting unit is colored and cut. . For this reason, when electric wire production data is input to the input section, a desired electric wire is produced promptly. Therefore, it is possible to shorten the time from ordering of the electric wire to production and shipment. Therefore, there is no need to predict the consumption in advance and manufacture the electric wires.

It is possible to suppress the portion where the coloring material mixes with the obtained coloring material, and to prevent a decrease in the yield of electric wires.

 In addition, the coloring unit squirts (drips) the coloring material by a fixed amount toward the outer surface of the electric wire. For this reason, the shape of the mark formed on the outer surface of the electric wire can be easily changed by changing the ejection amount and the ejection interval of the coloring material of the coloring unit. Therefore, the outer surface of the electric wire can be colored in a desired color without wasting the coloring material. Therefore, it is possible to suppress a rise in costs of electric wires and products using the electric wires.

In addition, the manufacturing department manufactures monochrome electric wires. For this reason, the types (color types) of electric wires stored in advance in the manufacturing department can be suppressed, and there is no need to manufacture electric wires in advance.

 The manufacturing section manufactures the required length of a single-color electric wire, and the coloring section colors the outer surface of the single-color electric wire to a desired color to form a desired mark. For this reason, the amount of electric wire stored between the manufacturing section and the coloring section can be suppressed.

For this reason, the space required for storing the electric wires in advance can be suppressed, and the space required for storing the electric wires during manufacturing can be suppressed. Therefore, it is possible to suppress a rise in the cost of the electric wire itself and the cost of a product using the electric wire. In addition, monochromatic wires will be manufactured to the required length, and the outer surface of the monochromatic wires will be colored and delivered to the ordering side. Therefore, no extra wires are generated between the time the wires are manufactured and delivered. Therefore, it is possible to prevent useless electric wires from being generated and to save resources.In addition, input electric wire production data indicating the required electric wire part number, length, shape and color of the mark, etc. to the input section. As a result, the production department produces the electric wires and the coloring section is colored.

Therefore, the time from ordering of the electric wire to production and shipment can be shortened. Therefore, there is no need to predict the consumption in advance and manufacture the electric wires. For this reason, it is possible to reliably prevent an extra stock of electric wires from occurring, and it is possible to suppress a rise in costs of the electric wires and products using the electric wires.

For this reason, the color for coloring the outer surface of the electric wire can be easily switched by switching the coloring unit that ejects (drops) the coloring material. Therefore, it is possible to easily color the outer surface of the electric wire with a desired color, and it is possible to suppress a portion where the colorant before the colorant is switched and the colorant after the colorant is switched, thereby preventing a decrease in the yield of the wire. The coloring unit emits a predetermined amount of coloring material toward the outer surface of the electric wire.
