The electric wire used for this wire harness is a conductor part made of a linear conductive member coated with an insulating material. The outer diameter of the conductor part, the material of the insulating material, or for power transmission, control signal transmission, etc. It is necessary to identify the type of wire, such as the purpose of use.
For this reason, the type of the electric wire is identified by coloring or patterning the insulating material of the electric wire.

  As a method of manufacturing such an electric wire, a wound electric wire bundle is formed by winding an electric wire obtained by continuously covering a conductor portion with an insulating material colored in a desired color at a predetermined size. When this type of electric wire manufacturing method is used, when the number of types of electric wires is large, it is necessary to make a large number of wound electric wire bundles according to the types of electric wires. For this reason, there has been a problem that a large number of cut ends of the electric wires are generated due to the generation of the cut ends of the wires after the cut in each of the wound electric wire bundles. Moreover, when the production amount of one type of electric wire becomes large, a wound wire bundle corresponding to only one type of wire may be made, and when the number of such wound wire bundles corresponding to only one type of wire increases. As a result, there is a problem in that the amount of broken wires is increased.

Therefore, for example, Patent Document 1 proposes a method of producing an electric wire that is colored to identify the type of the electric wire after the monochromatic electric wire is manufactured.
In the electric wire production method described in Patent Document 1, it is not necessary to create a wound wire bundle for each type of electric wire, and therefore the amount of broken ends of the electric wire can be reduced.

[First embodiment]
FIG. 1 is a schematic view of a wire harness factory 100 that manufactures a wound wire bundle 1 according to a first embodiment of the present invention. FIG. 2A is a perspective view of the electric wire drum 20 that holds the wound electric wire bundle 1 in a wound state. FIG. 2B is a perspective view of the wound wire bundle 1 wound around the wire drum 20 shown in FIG. 2A. 3A, 3B, and 3C are diagrams for specifically explaining the coloring portion 60 shown in FIG.

  The wound wire bundle 1 according to the present embodiment is a bundle of wires 10 used for a wire harness routed in a vehicle, and is manufactured in a wire harness factory 100 for manufacturing a wire harness. Moreover, the manufacturing method of the electric wire which concerns on this embodiment is a method of manufacturing an electric wire using this coiled wire bundle 1. FIG.

As shown in FIG. 1, the wire harness factory 100 is connected to the conductor covering portion 11 of the electric wire 10 with the insulation coating 12 and the downstream side of the extrusion covering portion 30, and is sent from the extrusion covering portion 30. An electric wire take-up unit 40 that winds the electric wire 10 to form the wound electric wire bundle 1, a coloring unit 60 that colors the wound electric wire bundle 1 for identifying the type of the electric wire 10, and an upstream side of the coloring unit 60 An electric wire supply unit 50 for supplying the electric wire 10 from the wound wire bundle 1 to the coloring unit 60, and a cutting unit 70 connected to the downstream side of the coloring unit 60 and continuously cutting the electric wire 10 with a predetermined dimension Is provided.
In addition, although not shown in FIG. 1, the apparatus for completing the wire harness 90 using the electric wire 10 cut | disconnected to the predetermined dimension by the cutting part 70, and the work area are provided in the wire harness factory 100. FIG. . Here, a plurality of electric wires 10 that have been cut to a predetermined size from the wound electric wire bundle 1 are bundled, and various components such as a connector C are attached to the ends of the electric wires 10 to complete the wire harness 90.
In the first embodiment, the coloring portion 60 is connected to the upstream side of the cutting portion 70. However, a line configuration in which the coloring portion 60 is connected to the downstream side of the cutting portion 70 may be used.

First, the wound wire bundle 1 will be described.
When the wire bundle 1 identifies the type of the electric wire 10 by coloring or patterning the insulating material 12, the minimum length necessary for continuously cutting two or more types of the electric wires 10 to be identified. Now, the electric wire 10 of the monochromatic insulating material 12 is bundled. In other words, the wound wire bundle 1 is configured by winding a single color (preferably uncolored) wire 10 and the length of the wound wire 10 is two or more types of identification objects. It is comprised so that it may become the minimum length (winding length) L (refer FIG. 5C) required in order to manufacture the electric wire 10. FIG.
Here, the minimum required length L of the electric wires 10 is specifically the same as the required number of the two or more types of electric wires 10 that are the same in the conductor portion 11 and the insulating material 12 and are to be identified. It is a total value (L = La + Lb + Lc) of the total length (La + Lb shown in FIG. 5C) and the minimum length required for processing (Lc shown in FIG. 5C).

The wound electric wire bundle 1 is obtained by winding an electric wire 10 covered with an insulating material 12 such as a synthetic resin on a conductor portion 11 made of a linear conductive member such as copper or aluminum.
More specifically, the wound wire bundle 1 is obtained by holding the wire 10 in a state of being wound around a so-called wire drum 20 (see FIG. 2A) as shown in FIG. 2B.
In addition, if the electric wire drum 20 can hold | maintain in the state which wound up the electric wire 10, a shape and a material will not be limited.

  The insulating material 12 is non-colored and is made of a synthetic resin such as polyvinyl chloride (PVC). Note that “non-colored” in the present specification means that the synthetic resin constituting the insulating material 12 is not colored and is the color of the synthetic resin itself.

Next, the extrusion coating | coated part 30, the electric wire winding part 40, the electric wire supply part 50, the coloring part 60, and the cutting part 70 are demonstrated.
The extrusion covering portion 30 is for extruding the insulating material 12 on the outer periphery of the conductor portion 11.

  The electric wire take-up unit 40 is a part that winds and bundles the electric wires 10 fed from the extruded covering unit 30. More specifically, the electric wire drum 20 is set in the electric wire winding portion 40, and the electric wire 10 is wound around the electric wire drum 20.

  The electric wire supply unit 50 sets the wound wire bundle 1 manufactured by the extrusion covering portion 30 and the wire winding portion 40 and sends the wire 10 to the coloring portion 60 while unwinding the wire 10 from the wound wire bundle 1. .

The coloring portion 60 is for coloring the outer surface 12a of the insulating material 12 using a so-called stamp-type coloring method.
As shown in FIGS. 3A, 3B, and 3C, the coloring portion 60 includes an ink tank 60a that contains a coloring liquid I such as dye ink, a pair of upper and lower stamp portions 60b and 60b made of a porous material, and an ink tank. And a felt part 60c for supplying the colored liquid I from 60a to the stamp part 60b.

  In such a coloring portion 60, the stamp portions 60b and 60b are spaced from each other from a standby state (see FIG. 3A) in which the pair of upper and lower stamp portions 60b and 60b come into contact with each other to prevent the coloring liquid I from drying. Then, the electric wire 10 is arranged between them (see FIG. 3B), and then the outer surface 12a is colored by the stamp portions 60b and 60b coming into contact with the outer surface 12a of the insulating material 12 (see FIG. 3C). ).

  In addition, the coloring part 60 is not limited to the stamp type described above, and may be other as long as the outer surface 12a of the insulating material 12 can be colored. For example, a so-called spray type that sprays the colored liquid I onto the outer surface 12a, or a combination of a stamp type and a spray type, or a stamp type coloring device described in JP2013-39550A is used. It doesn't matter.

  Moreover, in this 1st embodiment, although what colored the outer surface 12a of the insulating material 12 by the coloring part 60 was illustrated, not only this but the pattern which can identify the electric wire 10 is given to the outer surface 12a. It doesn't matter. Examples of the pattern include stamping, embossing, or a mark using a plurality of colors.

  The cutting unit 70 sequentially draws the colored wires 10 that have been colored from the coloring unit 60 with a predetermined length, and cuts the electric wires 10 into a predetermined dimension using a cutter (not shown). The plurality of electric wires 10 cut to a predetermined size by the cutting unit 70 are held by a receiving mechanism (not shown) so that they can be conveyed to a subsequent process.

  According to such a line configuration including the extrusion covering portion 30, the wire winding portion 40, the wire supply portion 50, the coloring portion 60, and the cutting portion 70, first, the extrusion covering portion 30 is performed according to the procedure described later. The uncolored electric wire 10 is continuously manufactured with the calculated winding length, and the wound wire bundle 1 is manufactured by winding the electric wire 10 fed out from the extrusion covering portion 30 by the electric wire winding portion 40. . This wound electric wire bundle 1 is obtained by winding up two or more types of electric wires 10 to be identified. In other words, the wound wire bundle 1 is a bundle of wires 10 having a minimum length L necessary for manufacturing two or more types of identification target wires 10 in the latter stage of the line configuration.

  Thereafter, the worker removes the wound wire bundle 1 from the wire winding unit 40 and sets it in the wire supply unit 50. The transfer work of the wound wire bundle 1 from the wire winding unit 40 to the wire supply unit 50 is because the wound wire bundle 1 winds up two or more types of identification target wires 10. There is no need to do this every time the type changes. The wound wire bundle 1 wound up by the wire winding unit 40 may be temporarily placed in the wire harness factory 100 until the processing after the coloring unit 60 is started.

Then, while unwinding the wire 10 from the wound wire bundle 1 in which the wire supply unit 50 is set, the wire 10 unwound from the wound wire bundle 1 is supplied to the coloring unit 60, and the coloring unit 60 determines the type of the wire 10. By coloring the electric wire 10 with a color for identification, and then cutting the electric wire 10 with the cutting portion 70 into a predetermined dimension, two or more types of electric wires 10 to be identified are continuously manufactured.
The extrusion covering portion 30, the wire winding portion 40, the wire supply portion 50, the coloring portion 60, and the cutting portion 70 shown in FIG. 1 can also be expressed as a “wire manufacturing system” for manufacturing the desired wire 10. . Moreover, the extrusion coating | coated part 30 and the electric wire winding-up part 40 can also be expressed as the "electric wire bundle manufacturing part" which manufactures the wound wire bundle 1. FIG. The coloring unit 60 can also be expressed as an “identification information adding unit” that adds identification information (color) corresponding to two or more types of the electric wires 10 to be identified to the outer surface 12 a of the electric wires 10.

Here, the procedure for calculating the winding length of the wound wire bundle 1 will be described with reference to FIGS. 4 and 5.
FIG. 4 is a flowchart showing a procedure for calculating the winding length of the wound wire bundle 1. FIG. 5A is a perspective view of the wound wire bundle 1 wound around the wire drum 20. FIG. 5B is a perspective view of the electric wire drum 20 and the electric wire 10 showing a state where the electric wire 10 wound around the electric wire drum 20 is unwound. FIG. 5C is a view for explaining the winding length of the wound wire bundle 1.

  Each process of the flowchart shown in FIG. 4 is performed by connecting a computer that controls the operations of the extrusion covering unit 30 and the wire winding unit 40 to a network system that transmits production management information such as manufacturing request information of the wire 10. Implemented by this computer. That is, the computer that controls the operations of the extrusion covering portion 30 and the wire winding portion 40 automatically calculates the winding length L of the wound wire bundle 1. This computer can also be expressed as a “winding length calculator”.

As shown in FIG. 4, first, the wire manufacturing request information related to the wire harness order information is input (input step), and from this manufacturing request information, the conductor portion 11 and the insulating material 12 are equal and different. The electric wire 10 that needs to display the identification information on the outer surface 12a of the insulating material 12 is extracted (extraction step) (step S101).
The electric wire manufacturing request information includes, for example, the type information of the electric wire 10 to be identified, that is, information on the type of color to be colored on the outer surface 12a of the insulating material 12, or the pattern to be applied to the outer surface 12a of the insulating material 12. Information, information on the outer diameter of the conductor portion 11, information on the material and thickness of the insulating material 12, information on the dimensions after cutting of the electric wire 10, and information on the required number are included.
Based on the manufacturing request information of the electric wire, the conductor part 11 and the insulating material 12 are equal, and information including the dimensions and the number of the electric wires 10 to be identified is extracted.
In the present embodiment, it is assumed that two types of electric wires 10 to be identified with the same conductor portion 11 and insulating material 12 are extracted. These two types of electric wires 10 to be identified include, for example, an electric wire 10 that is colored red for identification (hereinafter referred to as a red electric wire 10r) and an electric wire that is colored blue (hereinafter referred to as a blue electric wire 10b). Divided.

Next, based on the information of the two types of identification target electric wires 10 extracted in step S101, the minimum number of electric wires 10 required to wind the uncolored electric wires 10 as the wound electric wire bundle 1 (see FIG. 5A). The length is calculated (calculation step) (step S102).
Here, the minimum length L of the electric wires 10 (see FIG. 5B) required to manufacture the required number of red electric wires 10r and blue electric wires 10b cut to a predetermined size is calculated. Here, the minimum required length L of the electric wire 10 is the total length La for the required number of red electric wires 10r, the total length Lb for the required number of blue electric wires 10b, and the extra length required for processing. This is the sum of Lc (see FIG. 5C).

  The winding length L of the wound wire bundle 1 calculated in this way is used as processing instruction information for the extrusion covering portion 30 and the wire winding portion 40. As a result, the extruded covering portion 30 and the wire winding portion 40 can remove the wire 10 of the non-colored insulating material 12 with the minimum length L required to continuously cut the two types of the wires 10 to be identified. An electric wire bundling step (electric wire bundle manufacturing step) for forming a wound electric wire bundle 1 by winding is performed. Furthermore, the electric wire supply part 50 supplies the electric wire 10 unwound from the wound electric wire bundle 1 to the coloring part 60 while unwinding the electric wire 10 from the set electric wire bundle 1, and the coloring part 60 is shown in FIG. Based on the “information including dimensions and number of the two or more types of electric wires 10 to be identified” extracted in step S101 of the flowchart, the color of the electric wire 10 as identification information corresponding to the type of the electric wire 10 and the winding wire bundle 1 The outer surface of the electric wire 10 to be sent out is colored (addition step). Thereafter, the cutting unit 70 removes the electric wire 10 colored by the coloring unit 60 based on “information including dimensions and number of the electric wires 10 to be identified of two or more types” extracted in step S101 of the flowchart of FIG. Cut into predetermined dimensions corresponding to two or more types of wires 10 to be identified (cutting step). Thereby, the electric wire 10 of 2 or more types of identification object is manufactured continuously.

  If the types of electric wires 10 that need to be manufactured in large quantities are wound together with the types of electric wires 10 that only need to be manufactured in a small amount, the winding length L of the wound wire bundle 1 becomes extremely long. Only.

  Moreover, in the procedure of calculating the winding length L of the wound wire bundle 1, the configuration in which the computer automatically calculates the winding length L of the wound wire bundle 1 is illustrated. The length L may be calculated.

  In the method of manufacturing an electric wire according to the first embodiment, since the wound wire bundle 1 is made to bundle two types of identification target wires 10, the winding shape in which the identification target wires 10 are bundled one by one. Since the number of the wound wire bundles 1 can be reduced as compared with the wire bundle, it is possible to reduce the number of pieces of the wires 10 due to the wound wire bundle 1.

  Moreover, since the insulating material 12 of the coiled wire bundle 1 is uncolored, the method for manufacturing the electric wire according to the first embodiment selects many types of colors to be colored on the outer surface 12a of the insulating material 12 for identification. And a pattern for identification can be easily applied.

  Moreover, since it becomes possible for the manufacturing method of the electric wire which concerns on 1st embodiment to throw in the wound wire bundle 1 directly to a wire harness manufacturing line, the space which stores and temporarily places the wound wire bundle 1 is reduced. be able to.

  Moreover, since the wound wire bundle 1 according to the first embodiment is configured to wind two types of identification target wires 10, the wound wire bundle 1 is obtained by winding the identification target wires 10 one by one. In comparison, since the number of the wound wire bundles 1 can be reduced, it is possible to reduce the number of cut ends of the wires 10 due to the wound wire bundle 1.

  The electric wire manufacturing method of the first embodiment includes an input step of inputting manufacturing request information of the electric wire 10 in which the insulating material 12 is coated on the conductor portion 11 made of a metal wire, and the manufacturing request information input in the input step. Based on this, an extraction step (S101) for extracting information including the dimensions and number of the electric wires 10r and 10b to be identified, to which the identification information for identifying the type is given by coloring the outer surface 12a of the insulating material 12. ) And a calculation step (S102) for calculating the minimum length L of the electric wire 10 necessary for manufacturing two or more types of electric wires 10r and 10b to be identified based on the information extracted in the extraction step; The wire bundle manufacturing step for manufacturing the wound wire bundle 1 in which the wire 10 of the monochromatic insulating material 12 is wound with the length L calculated in the calculation step, and the extraction step Based on the output information, the electric wire 10 is sent out from the wound electric wire bundle 1 manufactured in the electric wire bundle manufacturing step with the color as the identification information corresponding to the two or more types of electric wires 10r and 10b to be identified. The size corresponding to two or more types of identification target wires 10r and 10b based on the information extracted in the extraction step, and the additional step of coloring the outer surface 12a of the ten and the electric wire 10 colored in the additional step A cutting step of cutting at La and Lb.

  Similarly, in the electric wire manufacturing system of the first embodiment, the outer surface 12a of the insulating material 12 is colored based on the manufacturing request information of the electric wire 10 in which the conductor portion 11 made of a metal wire is covered with the insulating material 12. Information including dimensions and number of the two or more types of identification target wires 10r and 10b to which identification information for identifying the type is given is extracted, and based on the extracted information, two or more types of identification target wires A winding length calculation unit (computer) for calculating the minimum length L of the electric wire 10 necessary for manufacturing 10r and 10b, and a monochromatic insulation with the length L calculated by the winding length calculation unit Based on the information extracted by the wire bundle manufacturing unit (the extrusion covering unit 30 and the wire winding unit 40) that manufactures the wound wire bundle 1 in which the wires 10 of the material 12 are wound, and the winding length calculation unit, Electrical wire A colored portion for coloring the outer surface 12a of the electric wire 10 sent out from the wound wire bundle 1 manufactured by the electric wire bundle manufacturing portion with a color as identification information corresponding to two or more types of electric wires 10r and 10b to be identified in 0 60 and a cutting unit 70 that cuts the electric wire 10 colored by the coloring unit 60 with dimensions corresponding to two or more types of electric wires 10r and 10b to be identified based on the information extracted by the winding length calculation unit. And.

  With these configurations, the wound wire bundle 1 is configured to bundle two types of identification target wires 10 (10r, 10b), and therefore the identification target wires 10 are bundled one by one. Since the number of the wound wire bundles 1 can be reduced as compared with the above, the amount of broken ends of the wires 10 caused by the wound wire bundle 1 can be reduced.

Wire bundle manufacturing steps S205 and S206 for manufacturing coiled wire bundles 312A and 312B, which are manufactured with a predetermined total length, and the manufactured plain wires 311A and 311B are wound, and wires calculated in wire quantity information calculation step S202 Based on the quantity information D3, the plain wires 311A, 311B are sent out from the wound wire bundles 312A, 312B made up of the plain wires 311A, 311B having the desired varieties and outer diameters r1, r2, and the fed plain wires 311A, 311B are sent out. In contrast, the plain electric wire of a desired color (identification symbol) for identifying the type of the electric wire 313 Electric wire manufacturing steps S208 and S209 for manufacturing electric wires 313A to 313D having desired physical information by coloring the outer surface 12a of 311A and 311B and cutting the plain electric wires 311A and 311B with a desired length. And including.

  With these configurations, the electric wires 313A to 313D necessary for manufacturing the ordered wire harness 90 are grouped into electric wire groups G1 and G2 having a common product type and outer diameter, and these electric wire groups G1 and G2 are grouped. It becomes possible to manufacture each electric wire 313A-313D from single coiled wire bundle 312A, 312B for every. For this reason, since the number of the wound wire bundles 312A and 312B used for manufacturing the desired wires 313A to 313D can be reduced, it is possible to reduce the number of pieces of wire that are generated for each of the wound wire bundles 312A and 312B. It is possible to reduce the generation amount of the broken ends of the electric wires 313 by the bundle of electric wires 312.

  Here, a conventional wound wire bundle is manufactured for each electric wire having common physical information such as the type of electric wire (material of conductor and insulator, product name, etc.), outer diameter, color and pattern of the outer surface. For example, it was manufactured by bundling a piece cut into a predetermined uniform length such as 500 to 2000 m. The length of the wire wound around the single wound wire bundle depends on the size of the wire drum around which the wire is wound. In other words, the conventional wound wire bundle was not manufactured at the wire harness factory because the length of the wire to be wound did not depend on the order quantity of the wire harness, and was fixed to a certain length. It was common to transport products manufactured at electric wire factories and the like. In this case, for example, when the order quantity of the wire harness is large and the usage amount of the same type of electric wire becomes two or more bundles of the wound wire bundle, it is necessary to replace the wound wire bundle during a series of wire manufacturing operations. If the bundle to be exchanged is missing or there is a shortage, the production efficiency may deteriorate, such as waiting for the arrival from the electric wire factory.

  On the other hand, in the present embodiment, the length of the electric wire (the plain electric wire 311 in the present embodiment) wound around the single wound electric wire bundle 312 is not uniformly determined, and the order quantity of the wire harness 90 is increased. It can be set accordingly. In the present embodiment, the electric wire drum 20 used for manufacturing the wound wire bundle 312 so that the same type of wires can be bundled into a single wound wire bundle 312 even in a situation where the order quantity of the wire harness 90 is large. For example, it is preferable to increase the size of the wire to a size larger than that of the conventional device to such an extent that an electric wire having a length approximately twice the conventional predetermined length can be wound. In this way, by manufacturing the wound wire bundle 312 with the length of the wire according to the order quantity of the wire harness 90, the wires of the wound wire bundle 312 are used up every time one or more orders of the wire harness 90 are received. Therefore, it is possible to reduce the frequency of replacement of the wound wire bundle 312 such as not to replace the wound wire bundle 312 during the manufacturing operation of the wire 313 according to one order, Improvement in work efficiency can be expected. In addition, since it is not necessary to manufacture the coiled wire bundle 312 before receiving an order for the wire harness 90, a storage space for the coiled wire bundle 312 is not required in the wire harness factory 300, thereby saving space. Further, after receiving an order for the wire harness 90, the necessary wound wire bundle 312 is manufactured based on the wire harness order information D2, and the desired wire 313 is manufactured using the manufactured wound wire bundle 312. Therefore, all the series of processes related to the manufacture of the electric wire 313 can be performed in the wire harness factory 300, and the production efficiency can be improved and the transportation cost between the factory can be reduced. Moreover, since the electric wire 313 required for manufacture of the wire harness 90 is automatically manufactured if the order quantity of the wire harness 90 is input, there is no need to input the type and quantity of the electric wire 313 to be manufactured individually. The input operation of information related to the manufacture of 313 can be simplified.

  Moreover, in the electric wire manufacturing system 302 of the second embodiment, the electric wire bundle manufacturing unit 307 manufactures a plurality of wound electric wire bundles 312A and 312B composed of plain wires 311A and 311B having different varieties or outer diameters r1 and r2. To do.

Then, the coloring unit 60 and the cutting unit 70 of the electric wire manufacturing unit 308 color and cut the plain wire 311 from the selected one wound wire bundle 312.

  With this configuration, a plurality of coiled wire bundles 312A and 312B are manufactured according to the order quantity of the wire harness 90, so that the plurality of coiled wire bundles 312A and 312B are received for each order of the wire harness 90 once or a plurality of times. It becomes possible to manufacture so that the plain wires 311A and 311B can be used up. Thereby, every time the manufacture of the electric wire related to the order of the wire harness 90 for a predetermined number of times is completed, the plurality of the wound wire bundles 312A and 312B can be exchanged at the same time, and thus the wound wire bundles 312A and 312B. Replacement frequency can be reduced, and improvement in production efficiency can be expected. In addition, the exchange time of the wound wire bundle 312 can be set other than the unit of order, and can be set for every predetermined period such as every month.
