Description

[Technical field]

[0001] The present disclosure relates to a method and an apparatus for manufacturing a wire harness. [Background technology]

[0002] Wire harnesses used in the bodies of automobiles and trains, and aircraft fuselages, are composed of multiple electric wires bundled together. When manufacturing wire harnesses, nailboard drawings are used. Here, a nailboard drawing is a drawing that shows the shape of the wire harness to be manufactured, in other words, the arrangement of the electric wires that make up the wire harness. Each electric wire is cut to a preset electric wire length, and multiple electric wires are arranged according to the electric wire arrangement shown in the nailboard drawing. Then, a restraining member is attached to the laid electric wire or electric wire bundle at a predetermined attachment position along the longitudinal direction of the electric wire, thereby manufacturing a wire harness (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-79775 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, since the nailboard drawing is a plane, it is difficult to display the radial position (hereinafter also referred to as the mounting level) of the wire where the restraining member is attached, and therefore it is difficult to instruct the worker who attaches the restraining member on the mounting level using the nailboard drawing.

[0005] The present disclosure aims to provide a nailboard diagram that makes it easy to instruct workers on installation levels. [Means for solving the problem]

[0006] One aspect of the present disclosure is a method for manufacturing a wire harness, the method comprising: an installation hierarchy acquisition step of acquiring information on an installation hierarchy that constitutes a wire harness and indicates a radial position at which a restraining member is attached to an electric wire to which the restraining member is attached; a nailboard diagram output step of outputting a nailboard diagram including a hierarchical display displayed in a different display mode depending on the information on the installation hierarchy acquired by the installation hierarchy acquisition step; and a correspondence table output step of outputting a correspondence table that indicates a correspondence between the hierarchical display and an example of a cross-sectional structure at the position at which the hierarchical display is displayed.

[0007] According to this configuration, the nailboard diagram includes a correspondence table showing the correspondence between the hierarchical display and an example of the cross-sectional structure at the position where the hierarchical display is displayed. The hierarchical display is displayed in different display modes depending on the information of the installation level. This allows the worker to determine the radial position on the wire where the restraining member is to be attached, based on the hierarchical display and example cross-sectional structure displayed on the nailboard drawing.

[0008] Therefore, by using the nailboard diagram, it is easy to instruct the worker on the mounting level, which is the radial position on the electric wire at which the restraining member is to be attached. [Brief description of the drawings]

[0010] [1. Configuration] A manufacturing method and manufacturing system 1 for a wire harness 500 according to an embodiment of the present disclosure will be described with reference to Figs. 1 to 7. In this embodiment, the manufacturing system 1 of the present disclosure will be described as an example used for manufacturing a wire harness 500 to be wired in a body of a railway car (mobile object). Note that the mobile object in which the wire harness 500 of this embodiment is used is not limited to a railway car, and the wire harness 500 may be used in an aircraft body or an automobile body.

[0011] FIG. 4 is a schematic diagram showing an example of the configuration of a wire harness 500 in this embodiment, in which a plurality of electric wires 501 for connecting devices mounted on a vehicle body are bundled together. Electric wire 501 transmits electric power, electric signals, etc. between connected devices. At the end of electric wire 501, connector 502 having a shape corresponding to the device to be connected is attached.

[0012] The wire harness 500 is provided with a restraining member 503 that bundles and restrains a plurality of electric wires 501. Examples of the restraining member 503 include a resin binding member such as an adhesive tape, a tube, or a cable tie, a metal binding member, and a waxed cord. The binding member may have a through hole. The through hole is for inserting a fixing member such as a bolt used to fix the wire harness 500 bundled by the binding member to the body of a railway vehicle.

[0013] In this embodiment, an example will be described in which the restraining member 503 is an adhesive tape. A portion of the wire harness 500 in which the multiple electric wires 501 are bundled will be referred to as a trunk 511, a position where the electric wires 501 branch off from the trunk 511 will be referred to as a branch point 512, and a portion branched off from the trunk 511 will be referred to as a branch 513.

[0014] 5 shows an example of a cross section perpendicular to the longitudinal direction of the electric wires 501 to which the restraining members 517 are attached in the wire harness 500 of the present embodiment. The restraining members 517 are attached to predetermined attachment positions along the longitudinal direction of the electric wires 501 constituting the wire harness 500.

[0015] 5, the present embodiment will be described by taking an example in which a plurality of electric wires 501 are bundled together and a protective member 515 is provided around the bundled electric wires 501. The protective member 515 here is a member that protects the plurality of electric wires 501 by covering the periphery of the plurality of electric wires 501. Note that the bundled plurality of electric wires 501 will also be referred to as an electric wire bundle hereinafter.

[0016] A so-called insulating protective member may be used as the protective member 515. For example, a fiber material woven in a mesh shape may be used as the protective member 515. Alternatively, a tube having elasticity may be used as the protective member 515. The material of the protective member 515 is not particularly limited, but in this embodiment, an example in which an insulating material is used as the material of the protective member 515 will be described.

[0017] In the following description, the far side of protective member 515 as viewed from multiple electric wires 501 will also be referred to as the outer side, and the near side as the inner side. 5, the restraining member 517 may be attached to both the inside and outside of the protective member 515. In addition, hereinafter, the restraining member 517 attached to the inside of the protective member 515 is also referred to as an inner layer restraining member 517a, and the restraining member 517 attached to the outside of the protective member 515 is also referred to as an outer layer restraining member 517b.

[0018] The restraining member 517 is provided, for example, to fix the electric wires 501 and the protective member 515. Specifically, for example, the inner layer restraining member 517a may be provided to fix the multiple electric wires 501 inside the protective member 515 in a bundled state and suppress the occurrence of misalignment, etc. Furthermore, the outer layer restraining member 517b may be provided to fix the protective member 515 and the multiple electric wires 501, in other words, the protective member 515 and the electric wire bundle.

[0019] In this embodiment, an example will be described in which the restraining member 517 is an adhesive tape. Also, in this embodiment, the adhesive tape used as the restraining member 517 has a predetermined tape width, and the example will be described in which the adhesive tape is wound once to fix each of the multiple electric wires 501 to each other, or to fix the multiple electric wires 501 to the protective member 515.

[0020] In this embodiment, the restraint member 517 is attached by wrapping the adhesive tape around it once, but the attachment method is not limited to this, and the restraint member 517 may be attached by wrapping it around it multiple times, for example.

[0021] Furthermore, the protective member 515 and the restraining member 517 may be attached to the multiple electric wires 501 constituting the wire harness 500 in the following procedure. That is, the multiple electric wires 501 are bundled together, and the multiple electric wires 501 are fixed to each other using the inner layer restraining member 517a. In a state in which the multiple electric wires 501 are bundled and fixed by the inner layer restraining member 517a, the protective member 515 is further provided on the circumferential surface thereof, and the outer layer restraining member 517b is attached to the outer circumferential surface of the protective member 515.

[0022] It should be noted that the restraining member 517 is not limited to being attached to both the inside and outside of the protective member 515, but may be provided on either the inside or the outside. Hereinafter, the radial position where the restraining member 517 is attached is also referred to as the attachment layer. The attachment layer is, for example, information indicating whether the position where the restraining member 517 is attached is inside or outside the protective member 515. The attachment layer may further include information indicating that the restraining member 517 is attached both inside and outside, or information indicating that the restraining member 517 is attached neither inside nor outside.

[0023] The information on the installation hierarchy is represented as a hierarchical display 601 in a nailboard drawing 600 described later, and an example will be described in which a worker who manufactures the wire harness 500 attaches the restraining member 517 and the protective member 515 to the electric wire 501 in accordance with the hierarchical display 601 shown in the nailboard drawing 600 in which the information on the installation hierarchy is shown, and the explanation will be given below.

[0024] The configuration of the manufacturing system 1 and the configuration of the manufacturing apparatus 200 will be described with reference to FIGS. Fig. 3 is a block diagram showing an example of the configuration of the manufacturing system 1 in this embodiment. Also, Fig. 6 is a schematic diagram showing an example of the configuration of the manufacturing apparatus 200 in this embodiment.

[0025] 3 and 6, the manufacturing system 1 includes a manufacturing device 200 that manufactures the wire harness 500. The manufacturing system 1 will be described as further including a design device 100 that designs the wire harness 500. The design device 100 and the manufacturing device 200 are connected to each other via a dedicated information communication line or an information communication network so that information can be communicated between them.

[0026] The design device 100, for example, designs a wire harness 500 in a design space, which is a virtual space, and outputs data used to manufacture the wire harness 500. In this embodiment, the design device 100 is described as an information processing device such as a personal computer or a server having a CPU (Central Processing Unit), ROM, RAM, an input / output interface, etc.

[0027] Note that the configuration is not limited to the design device 100 as long as it can output data used to manufacture the wire harness 500, and may be, for example, a configuration that stores data used to manufacture the wire harness 500. In addition, the configuration that stores data used to manufacture the wire harness 500 is not limited to being provided in the design device 100, and may be provided in the manufacturing device 200.

[0028] The data used to manufacture the wire harness 500 includes, for example, drawing data, data of the protective member 515, data of the restraining member 517, and data of the restraining member 503.

[0029] The drawing data includes layout data showing the layout of electric wires 501 that constitute the wire harness 500. The arrangement data is information about the shape of the wire harness 500, such as length information of the main line 511 of the wire harness 500, position information of the branch point 512, and length information of the branch line 513. The data of the wire harness 500 also includes information that allows the wire harness 500 to be displayed as a two-dimensional drawing. The data of the wire harness 500 also includes information about the length of the electric wires 501 that constitute the wire harness 500.

[0030] In addition, the data of the wire harness 500 may include information regarding the wires 501 that constitute the wire harness 500, such as diameter information of the wires 501 that constitute the wire harness 500, and information identifying the wires 501 that constitute the branch wires 513.

[0031] The data of the restraining member 517 includes information on the attachment position of the restraining member 517 and information on the attachment layer of the restraining member 517. The attachment position here refers to a position where the restraining member 517 is attached to the electric wires 501 constituting the wire harness 500, and refers to a position along the longitudinal direction of the electric wires 501 constituting the wire harness 500. The attachment layer refers to a position where the restraining member 517 is attached to the electric wires 501 constituting the wire harness 500, and refers to a position in the radial direction of the electric wires 501 constituting the wire harness 500. In this embodiment, the attachment layer represents the outside and the inside with respect to the position of the protective member 515. In other words, the attachment layer represents whether the attachment layer is located closer to the electric wires 501 than the protective member 515 or farther from the electric wires 501 in the radial direction of the electric wires 501 in the wire harness 500.

[0032] Furthermore, the data on the restraining member 517 may include diameter information and length information along the longitudinal direction of the restraining member 517 in a state in which the restraining member 517 is provided. The data on the protective member 515 includes information on the position of the protective member 515 placed on the electric wire 501. The data may further include information on the placed protective member 515, such as diameter information of the electric wire 501 and the protective member 515 in a state in which the protective member 515 is provided, length information along the longitudinal direction, and information for identifying the electric wire 501 on which the protective member 515 is provided.

[0033] The data on restraining member 503 may include information on the type of restraining member 503, information on the number of turns to restrain, information on the outer diameter of the bundle of electric wires 501 after restraint, information on the length (amount of use) of restraining member 503, and information on the restraining position.

[0034] The drawing data may also include digital board information for the harness. The digital board information for the harness may include, for example, information for identifying the electric wires 501 constituting the wire harness 500 and information for identifying the connectors 502 attached to the electric wires 501.

[0035] The drawing data may include size information related to the size of the board display unit 202 to be output. Details of the board display unit 202 will be described later, but the board display unit 202 is a display surface on which the drawing data is displayed, and is also a placement surface on which the electric wires 501 are placed (laid) when the wire harness 500 is created in the harness digital board 201.

[0036] The manufacturing apparatus 200 is used to manufacture the wire harness 500. The manufacturing apparatus 200 includes a harness digital board 201, a control computer 211, and a data server 221, as shown in FIGS.

[0037] The harness digital board 201 is formed in a desk shape and used in manufacturing the wire harness 500. The harness digital board 201 is provided with a board display unit 202 which also serves as a workbench used in manufacturing the wire harness 500. The harness digital board 201 may include a plurality of board display units 202. The board display units 202 may each have a rectangular outer shape, and the sides of the board display units 202 may be in contact with each other to form the harness digital board 201.

[0038] Board display unit 202 is a surface having a width and length necessary for manufacturing wire harness 500. Board display unit 202 is the surface on which wire harness 500 is manufactured, and is also a display surface on which drawing data, which is digital information, is displayed. Board display unit 202 is connected to control computer 211 so as to be capable of communicating information, and data such as nailboard drawing 600 (described later) is sent from control computer 211.

[0039] The harness digital board 201 may be of a size according to the length of the harness to be manufactured. For example, when a larger harness is to be manufactured, a larger harness digital board 201 may be used. Here, the size of the harness digital board 201 may be realized by, for example, increasing the number of board display units 202 constituting the harness digital board 201, or by increasing the size of each of the board display units 202 constituting the harness digital board 201.

[0040] In this embodiment, the display surface of the board display unit 202 is a liquid crystal display. The display surface of the board display unit 202 is not limited to the above-mentioned liquid crystal display, and may be an organic EL (electroluminescence) display or a projection surface onto which the nail board drawing 600 is projected by a projector.

[0041] The control computer 211 controls the display of the nailboard drawing 600 on the harness digital board 201 . In this embodiment, the control computer 211 is an information processing device such as a personal computer having a CPU (Central Processing Unit), ROM, RAM, an input / output interface, and the like.

[0042] The programs stored in the storage device such as the ROM described above cause the CPU, ROM, RAM, and input / output interface to cooperate with each other to function as an input / output unit 212 and a control unit 213, as shown in FIG.

[0043] The input / output unit 212 is connected to the design device 100, the board display unit 202, and the data server 221 so as to be able to communicate information with them. In this embodiment, the input / output unit 212 is connected to the board display unit 202 and the data server 221 so as to be able to communicate information with them via wired communication using, for example, a LAN (Local Area Network) cable or the like, and the input / output unit 212 is connected to the design device 100 so as to be able to communicate information with them using an information communication network. Note that the manufacturing device 200 is not limited to a configuration having the input / output unit 212, and may be a configuration not having the input / output unit 212.

[0044] The control unit 213 generates a control signal for controlling the operation of the board display unit 202. The control unit 213 also causes the data server 221 to store information relating to the manufacture of the wire harness 500.

[0045] The data server 221 is a server connected to the control computer 211 so as to be capable of communicating information with the control computer 211 via an information communication network constituted by a LAN cable or the like. In this embodiment, the data server 221 will be described as an example in which the data server 221 is an information processing device such as a server having a CPU (central processing unit), a ROM, a RAM, an input / output interface, and the like.

[0046] 6, the program stored in the storage device such as the ROM causes the CPU, the ROM, the RAM, and the input / output interface to cooperate with each other to function as the storage unit 222. The storage unit 222 stores information related to the manufacture of the wire harness 500, such as the work history and the inspection results acquired by the control computer 211. The storage unit 222 may also store information used in the manufacture, including drawing data.

[0047] The harness digital board 201 corresponds to an example of a configuration as a display device, and the board display unit 202 corresponds to an example of a configuration as a display screen. In this embodiment, an example of a nailboard drawing 600 output to the board display unit 202 of the harness digital board 201 will be described with reference to FIG.

[0048] 1 , in a nailboard diagram 600, the arrangement of the electric wires 501 is displayed as an electric wire display 605 based on arrangement data showing the arrangement of the electric wires 501. A protective member display 603 showing a protective member 515 attached to the electric wires 501 and a hierarchical display 601 showing the installation hierarchical level of the restraining member 517 may be displayed, for example, superimposed on the electric wire display 605 showing the arrangement of the electric wires 501. Note that the hierarchical display 601 is displayed at the installation position where the restraining member 517 is attached, along with the arrangement of the electric wires 501 shown by the electric wire display 605.

[0049] FIG. 2 is an explanatory diagram showing the correspondence between the installation hierarchy and the hierarchy display 601 displayed in a display mode according to the installation hierarchy. In the table shown in Figure 2, from the leftmost column, there are shown an example of a display in a nailboard diagram 600, an example of a hierarchical display 601 which is a display showing the installation hierarchy, and an example of a cross section perpendicular to the longitudinal direction of the wire 501 at the location where the hierarchical display 601 is shown.

[0050] In addition, in the display of the nailboard diagram 600, the length along the longitudinal direction of the layer display 601 may be displayed, for example, as a length corresponding to the width of the restraining member 517. Specifically, it may be displayed as a length that matches the tape width of the restraining member 517 attached to the mounting layer.

[0051] In addition, the hierarchical display 601 is displayed in different display modes, such as colors, characters, symbols, and figures, depending on the installation level. Specifically, for example, when the installation level is only the outside, the display mode may be a filled-in display mode. When the installation level is only the inside, the display mode may be a display mode in which the characters "inside" are displayed. When the installation level is both the outside and the inside, the display mode may be a display mode in which a symbol such as "*" is used. Note that each display mode is not limited to these display modes, and various colors, characters, symbols, figures, and the like may be used. Specifically, for example, when the installation level is only the outside, the display mode may be a display mode in which the characters "outside" are displayed.

[0052] In addition, when the hierarchical display 601 is in a display mode using characters, the language may be converted to a language set in advance. For example, the language may be converted to a language in a region where the manufacturing apparatus 200 is used, and specifically, when the manufacturing apparatus 200 is used in China, the language may be converted to Chinese.

[0053] Furthermore, when the nailboard diagram 600 is displayed as an image by the board display unit 202, the images may be distinguished by dynamic display modes such as blinking depending on the installation level. The dynamic display mode here refers to a display mode that changes over time.

[0054] 1 and 2, the nailboard drawing has a protective member display 603 which is a display indicating that protective member 515 is provided at the position where protective member 515 is to be provided. Specifically, the position where protective member 515 is to be provided is indicated by displaying a hatched line or the like at the position where protective member 515 is to be provided (see the second line from the top in FIG. 2, and see FIG. 1). Also, the following description is applied to an example where the hatched line is not displayed to indicate a portion on the nailboard drawing 600 where protective member 515 is not provided (see the left side of the display example, the fifth line from the top in FIG. 2, and see FIG. 1).

[0055] In addition, in the nailboard diagram 600, the hierarchical display 601 and the protective member display 603 may be displayed with a width and length corresponding to the diameter and length of each member such as the restraining member 517 and the protective member 515 when attached to the electric wire 501.

[0056] [2. Effect] Next, the output process of the nailboard drawing 600 executed by the control unit 213 will be described with reference to FIG.

[0057] In S110, the control unit 213 acquires drawing data from the design device 100. Specifically, the control unit 213 acquires arrangement data representing the arrangement of the electric wires 501 that configure the wire harness 500 included in the drawing data.

[0058] The drawing data may be acquired from the design device 100 by a request from the manufacturing device 200 to the design device 100 for the drawing data, or may be acquired by transmitting the drawing data to the manufacturing device 200 by performing a predetermined operation on the design device 100, thereby causing the manufacturing device 200 to acquire the drawing data. Note that the acquisition of the drawing data is not limited to that from the design device 100, and data previously stored in the manufacturing device 200 may be acquired. The storage of the drawing data in the manufacturing device 200 may be, for example, in the storage unit 222. Furthermore, the control unit 213 may acquire data on the diameter and length of the electric wire 501 together with the arrangement data.

[0059] In S120, the control unit 213 acquires data on the protective member 515 and data on the restraining member 517 from the design device 100. Specifically, the data on the protective member 515 acquired by the control unit 213 from the design device 100 includes information on the position of the protective member 515. Information on the protective member 515 to be placed, such as diameter information on the electric wire 501 and the protective member 515 in a state in which the protective member 515 is provided, and information specifying the electric wire 501 on which the protective member 515 is provided, may also be included. The data on the protective member 515 acquired by the control unit 213 from the design device 100 includes data on the restraining member 517 including information on the mounting position of the restraining member 517 and information on the mounting layer of the restraining member 517.

[0060] The data of the protective member 515 and the restraining member 517 may be acquired by the manufacturing apparatus 200 requesting the design apparatus 100 for the data of the restraining member 517, or may be acquired by performing a predetermined operation on the design apparatus 100 and transmitting the data of the restraining member 517 to the manufacturing apparatus 200, causing the manufacturing apparatus 200 to acquire the data of the restraining member 517. Note that acquisition of the data of the restraining member 517 is not limited to being performed from the design apparatus 100, and may be data that has been previously stored in the manufacturing apparatus 200. The data of the restraining member 517 in the manufacturing apparatus 200 may be stored in the storage unit 222, for example.

[0061] In S130, the control unit 213 combines the arrangement of the electric wire 501 represented by the arrangement data with the arrangement of the protective member 515 and the restraining member 517. Specifically, the position of the electric wire 501 represented by the arrangement data is created as an electric wire display 605 in the nailboard drawing 600, and the hierarchical display 601 and the protective member display 603 are combined by superimposing it on the created electric wire display 605.

[0062] The hierarchical display 601 is synthesized so as to be displayed in a display mode representing the mounting level at the mounting position where the restraining member 517 is attached. That is, the hierarchical display 601 corresponding to the mounting level is synthesized at a position corresponding to the mounting position of the electric wire display 605. The hierarchical display 601 corresponding to the mounting level may be synthesized by referring to the correspondence between the mounting level and the hierarchical display 601 as shown in FIG. 2, which is stored in advance. The correspondence between the mounting level and the hierarchical display 601 may be stored in the control computer 211, for example, or may be acquired from the storage unit 222 of the data server 221.

[0063] Furthermore, the protective member display 603 is synthesized at the position of the electric wire 501 represented by the electric wire display 605, where the protective member 515 is provided. The protective member display 603 may be synthesized by synthesizing a predetermined display representing the protective member 515.

[0064] Furthermore, the hierarchical display 601 and the protective member display 603 may be displayed in a size and length according to the diameter and length of the portion after the restraining member 517 or the protective member 515 is attached. The diameter and length of the portion after the attachment may be acquired from the data of the restraining member 517 and the data of the protective member 515.

[0065] In S140, the control unit 213 outputs the nailboard drawing 600 in which the electric wire display 605 is combined with the hierarchical display 601 and the protective member display 603 in S130 to the harness digital board 201. The nailboard drawing 600 is displayed on the board display unit 202 included in the harness digital board 201 in a usable form. That is, in this embodiment, the nailboard drawing 600 is an image displayed on the board display unit 202. The usable form referred to here means a form in which at least the electric wires 501 can be laid on the harness digital board 201 and the wire harness 500 can be manufactured.

[0066] The process in S120 corresponds to an example of an attachment position acquisition step and an attachment level acquisition step, and the processes in S130 and S140 correspond to an example of an output step. The configuration for performing the process in S120 corresponds to an example of a configuration as an attachment position acquisition unit and an attachment level acquisition unit, and the configuration for performing the process in S130 and S140 corresponds to an example of a configuration as an output unit.

[0067] [3. Effects] (1) The manufacturing method of the wire harness 500 shown in the above embodiment includes an attachment position acquisition step, an attachment layer acquisition step, and an output step. In the attachment position acquisition step, information on an attachment position along the longitudinal direction of the wires 501 of the restraining member 517, which is a member attached to the wires 501 constituting the wire harness 500, is acquired. In the attachment layer acquisition step, information on an attachment layer indicating a radial position at which the restraining member 517 is attached to the wires 501 is acquired. In the output step, a nailboard drawing 600 including a layer display 601 displayed in a different display mode according to the information on the attachment layer acquired in the attachment layer acquisition step is output in a usable mode at the attachment position indicated by the information on the attachment position acquired in the attachment position acquisition step.

[0068] Moreover, the manufacturing apparatus 200 for the wire harness 500 shown in the above embodiment includes an attachment position acquisition unit, an attachment layer acquisition unit, and an output unit. The attachment position acquisition unit acquires an attachment position of a restraining member 517, which is a member attached to the electric wire 501 constituting the wire harness 500, along the longitudinal direction of the electric wire 501. The attachment layer acquisition unit acquires information on an attachment layer representing a radial position at which the restraining member 517 is attached to the electric wire 501. The output unit outputs, in a usable manner, a nailboard drawing 600 including a layer display 601 displayed in a different display mode according to the information on the attachment layer acquired by the attachment layer acquisition unit, at the attachment position represented by the information on the attachment position acquired by the attachment position acquisition unit.

[0069] According to this configuration, the nailboard diagram 600 includes a hierarchical display 601. The hierarchical display 601 is displayed in a different display mode depending on the information of the installation hierarchy. This allows the worker to determine the installation level based on the display format of the level display 601 displayed on the nailboard diagram 600.

[0070] Therefore, by using the nailboard diagram 600, it becomes easy to instruct the worker on the installation level. Specifically, there is no need to use diagrams for each step of installing the inner layer restraint member 517a, the protective member 515, and the outer layer restraint member 517b; the installation level can be determined by using a nailboard diagram 600 including the level display 601.

[0071] In addition, since the installation level can be determined from the display mode, instructions in the form of letters can be omitted, which simplifies the instructions for manufacturing. (2) In the above embodiment, the wire harness 500 includes the electric wire 501 and the protective member 515. The protective member 515 is located on the circumferential surface of the electric wire 501. The hierarchical display 601 is displayed in a different display mode depending on whether the radial position at which the restraining member 517 is attached to the electric wire 501 is inside or outside the protective member 515.

[0072] With this configuration, the worker can determine whether the radial position at which the restraining member 517 is to be attached is inside or outside the protective member 515, based on the display mode of the hierarchical display 601 displayed on the nailboard diagram 600.

[0073] Therefore, by using the nailboard diagram 600, it is easy to instruct the worker whether the radial position at which the restraining member 517 is to be attached is on the inside or outside of the protective member 515.

[0074] (3) In the above embodiment, the hierarchical display 601 included in the nailboard diagram 600 is displayed in a different manner when the mounting layer, which is the radial position at which the restraining member 517 is attached to the electric wire 501, is both inside and outside the protective member 515, compared to when the mounting layer, which is the radial position at which the restraining member 517 is attached to the electric wire 501, is either inside or outside the protective member 515.

[0075] With this configuration, the worker can determine, based on the display mode of the hierarchical display 601 displayed on the nailboard diagram 600, whether the radial position at which the restraining member 517 is attached is either inside or outside the protective member 515, or both.

[0076] Therefore, by using the nailboard diagram 600, it is easy to instruct the worker as to whether the radial position at which the restraining member 517 is to be attached is on either the inside or outside of the protective member 515, or both.

[0077] (4) In the above embodiment, the hierarchy display 601 included in the nailboard diagram 600 may be displayed in a display manner in which at least one of the colors, characters, symbols, and figures representing the installation hierarchy at the installation position is different.

[0078] According to this configuration, at least one of the colors, letters, symbols, and figures representing the installation level is displayed in a different display manner, thereby enabling the worker to determine the installation level based on the display manner of the colors, letters, symbols, and figures.

[0079] Therefore, by using the nailboard diagram 600, it becomes easy to instruct the worker on the radial position where the component is to be attached. (5) In the above embodiment, the nailboard drawing 600 includes a protective member indication 603 that indicates the position where the protective member 515 is provided on the periphery of the electric wire 501 .

[0080] According to this configuration, protective member marking 603 indicating the position where protective member 515 is to be provided on the peripheral surface of electric wire 501 enables the worker to determine the attachment position of protective member 515 from nailboard diagram 600.

[0081] Therefore, by using the nailboard diagram 600, it becomes easy to indicate the position where the protective member 515 is to be attached. (6) In the above embodiment, the nailboard drawing 600 output in the output step is an image displayed in a usable format on at least one display screen of the display device.

[0082] According to this configuration, wire harness 500 can be manufactured by laying electric wires 501 on nail board drawing 600 displayed on board display unit 202 and attaching members.

[0083] [4. Other embodiments] (1) The technical scope of the present disclosure is not limited to the above-described embodiment, and various modifications may be made without departing from the spirit and scope of the present disclosure.

[0084] (2) In the above embodiment, a portion of the nailboard diagram 600 may be configured to display a correspondence table showing the correspondence between the installation hierarchy and the display form of the hierarchy display 601 shown in Figure 2, and an example of the cross-sectional structure at the position where the hierarchy display 601 is displayed.

[0085] According to such a configuration, since it is possible to attach the restraining member 517 while checking the correspondence table, the attachment work of the restraining member 517 becomes easier. The data in the correspondence table may be stored in the same manner as the data used in manufacturing the wire harness 500 .

[0086] (3) In the above embodiment, the nailboard drawing 600 is output by displaying it on the board display unit 202 provided in the harness digital board 201. However, the output of the nailboard drawing 600 is not limited to being output by displaying it on the board display unit 202 provided in the harness digital board 201. As a modified example, FIG. 8 shows an example of a manufacturing system 2 including a printing device 300. For example, as shown in FIG. 6, the manufacturing system 2 may include the printing device 300, and the nailboard drawing 600 may be output by printing from the printing device 300. That is, as shown in FIG. 6, the manufacturing system 2 may include the printing device 300 instead of the harness digital board 201, or may include the printing device 300 together with the harness digital board 201.

[0087] In other words, in the above embodiment, in the output step, nailboard drawing 600 is an image output to board display unit 202 provided in digital board 201 for harness. However, nailboard drawing 600 is not limited to being displayed as an image, and may be a printed matter output by printer 300. Furthermore, nailboard drawing 600 output by printing may be used in a state of being attached to a nailboard. Specifically, electric wires 501 may be laid along nailboard drawing 600 attached to the nailboard, and wire harness 500 may be manufactured.

[0088] (4) In the above embodiment, the restraining member 517 is described as an example of being an adhesive tape. The adhesive tape as the restraining member 517 has a predetermined tape width and is attached to the attachment layer at the attachment position. Here, the restraining member 517 is described as being attached by wrapping it around the electric wire 501 or the protective member 515 once. However, the attachment of the restraining member 517 is not limited to wrapping the adhesive tape as the restraining member 517 around the multiple electric wires 501 once, and may be attached by wrapping it multiple times, for example. Here, when wrapping it multiple times, it may be wrapped multiple times around the same attachment position. In other words, it may be wrapped without moving the position where it is wrapped along the longitudinal direction of the electric wire 501.

[0089] On the other hand, when winding multiple times, the winding position may be moved along the longitudinal direction of electric wire 501. In other words, the adhesive tape as restraining member 517 may be wound while being shifted along the longitudinal direction of electric wire 501.

[0090] In such a case, the indication of the attachment position may be wider than the tape width. In other words, it may indicate the range where the restraining member 517 is attached (wrapped around). Note that the range where the restraining member 517 is attached is also referred to as the attachment range below.

[0091] The information on the attachment range may be stored together with the attachment position or instead of the attachment position, and the attachment range may be displayed according to the information on the attachment range. Note that, hereinafter, the display of the attachment range is also referred to as a range display.

[0092] According to this configuration, the hierarchy display 601 is displayed together with the range display showing the installation range, so that the worker can determine the installation range and the installation hierarchy from the nailboard diagram 600.

[0093] Therefore, by using the nailboard drawing 600, it becomes easy to indicate the range in which the restraining member 517 is to be attached and the radial position in which the restraining member 517 is to be attached to the worker.

[0094] (5) In the above embodiment, the attachment of the protective member 515 and the restraining member 517 and the manufacturing of the wire harness 500 may be configured to be performed automatically using a machine. (6) In the above embodiment, S120 corresponds to an example of the mounting position acquisition step and the mounting level acquisition step. However, S120 is not limited to being an example of the mounting position acquisition step and the mounting level acquisition step. Specifically, the mounting position acquisition step and the mounting level acquisition step may be executed separately.

[0095] (7) In the above embodiment, the hierarchical display 601 differs depending on whether it is inside or outside the protective member 515. However, the hierarchical display 601 is not limited to being different depending on whether it is inside or outside the protective member 515, and the display mode may be different depending on whether it is inside or outside with respect to another member.

[0096] (8) In the above embodiment, the attachment position and attachment level of restraining member 517 are displayed on the nailboard drawing. However, the configuration in which the attachment position is displayed on the nailboard drawing is not limited to restraining member 517, and the position at which restraining member 503 is attached may also be displayed on the nailboard drawing in the same manner as the attachment position. In this case, the attachment positions of restraining member 503 and restraining member 517 may be displayed in different display modes.

[0097] (9) In the above embodiment, the description has been given of an example in which restraining member 503 and restraining member 517 are both adhesive tapes, but restraining member 503 and restraining member 517 are not limited to adhesive tapes as long as they are used as restraining member 503 and restraining member 517, and different materials may be used for each. For example, a cable tie may be used for restraining member 503, and a tube may be used for restraining member 517.

[0098] (10) In the above embodiment, the nailboard drawing 600 is generated by combining the protective member 515 and the restraining member 517 with the electric wire representation 605 representing the electric wire 501, but the present invention is not limited to such a method.

[0099] (11) In the above embodiment, the data used to manufacture the wire harness 500 includes the drawing data, the data of the protective member 515, the data of the restraining member 517, and the data of the restraining member 503. However, each piece of data may be configured such that one piece of data includes the other piece of data. Also, information included in each piece of data may be included in the other piece of data.

[0100] (12) Multiple functions possessed by one component in the above embodiments may be realized by multiple components, or one function possessed by one component may be realized by multiple components. Also, multiple functions possessed by multiple components may be realized by one component, or one function realized by multiple components may be realized by one component. Also, part of the configuration of the above embodiments may be omitted. Also, at least part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments. [Explanation of symbols]
