Description

  The present invention relates to a wire harness manufacturing method and a wire harness manufacturing apparatus that can be used to manufacture a wire harness mounted on a vehicle or the like in order to connect between a power source and various electrical devices.

  A wire harness mounted on a vehicle is used, for example, to connect between a power source on the vehicle and various electrical devices on the vehicle, or to electrically connect between electrical devices, and is included in the wire harness. Each of the many electric wires is used for supplying electric power to various electric devices and transmitting various signals. In addition, since various electrical devices are mounted at various positions on the vehicle, the wire harness has a complicated structure and can be passed through a route specified according to the structure and specifications of the vehicle. It is formed. In addition, a connection terminal is fixed to each tip of a large number of electric wires included in the wire harness by crimping, and the terminal of each electric wire is inserted into the cavity of the connector housing. That is, since the connector is attached to the end of the wire harness, the wire harness can be connected to the target electrical device through the connector. A number of connectors are added to a general wire harness so that it can be connected to various electrical devices.

  Patent Documents 1 to 3 are known as related arts of wire harnesses used in vehicles. Such a wire harness is generally configured as an aggregate of a plurality of sub-harnesses prepared for each system, for example. The sub-harness to be bundled differs depending on the specifications required for the wire harness.

  Specifically, which car model and which grade (superlative grade, speed model, low-priced grade, etc.), the required options (automatic adjustment function of seat back angle, fog lights, rear seat monitor The electrical components required for the vehicle differ depending on the presence / absence, etc., and for this reason, the circuit lines constituting the power line, the ground line, the signal line, and the communication line connected to the electrical component differ. In order to cope with such differences in circuit lines, for example, a collection of circuit lines for driving the electrical system in units of electrical systems is used as a sub-harness, and specifications required according to vehicle type, grade, and options Sub-harnesses corresponding to the above are selected, and the sub-harnesses are bundled to form one wire harness.

  Patent Document 1 shows a technology that facilitates production management in the production of wire harnesses, increases production efficiency, and easily copes with production fluctuations and design changes. Specifically, the wire harness is divided into a shared circuit and a dedicated circuit, and the shared circuit and the dedicated circuit of the electrical system related to the shared circuit are connected using a branch connector.

  Patent Document 2 shows a technology that facilitates production management in the production of wire harnesses, increases production efficiency, and easily copes with production fluctuations and design changes. Specifically, the wire harness is divided into a shared circuit and a dedicated circuit, and the shared circuit and the dedicated circuit of the electrical system that can be selected are tabulated and production controlled.

  Patent Document 3 shows a technique for performing work distribution with higher production efficiency in distributing load data to an automatic manufacturing apparatus when performing multi-product production. Specifically, material data including information about parts constituting the product is formed from the order data of the product. Further, a combination group is formed for each lot by acquiring all combinations that can be assigned to the automatic manufacturing apparatus based on the formed material data. The formed combination groups are given to the automatic manufacturing apparatus in the order of lots, and work is distributed.

  For example, as shown in Patent Document 2, the wire harness is divided into a shared circuit (base harness structure) and a dedicated circuit (optional harness structure) and managed, thereby managing the product number of the wire harness In addition, management of manufacturing becomes easy. That is, even when manufacturing wire harnesses to be mounted on various vehicles, the types and product numbers of base harness structures can be reduced. In addition, for example, when the user designates the type and presence of various optional electrical equipment, a wire harness having various configurations that satisfy the requirements can be manufactured simply by selecting, adding, or deleting an optional harness structure. Can do.

  For example, if a sub-harness for connecting an optional electrical device is incorporated in the wire harness as a basic component regardless of whether or not the electrical device is mounted, the number of wire harness types and product numbers can be reduced. Is possible. However, in that case, when the optional electrical device is not installed in an actual vehicle, it includes a useless sub-harness that is not used (discarded). Component cost increases.

  On the other hand, automation of the wire harness manufacturing process has been realized at a high rate in recent years. That is, manufacture of robots etc. for work processes such as cutting of electric wires that are parts of wire harnesses, transporting electric wires, attaching terminals (crimping) to the ends of electric wires, and inserting terminals of electric wires with terminals into connector housings Automation is possible by using equipment.

  However, as the structure of the wire harness becomes more complicated, the number of options for electrical equipment increases, and the number of types of wire harnesses increases, the number of work processes that cannot be automated in wire harness production increases, and the number of processes increases. There is a high possibility of fluctuations, which hinders the reduction of manufacturing costs.

  For example, consider a case where one sub-harness (Sub1) of the base harness structure and one sub-harness (Sub2) of the optional harness structure are connected to a common single connector housing (CH1). When the connector housing (CH1) exists on the sub-harness (Sub1) side, the terminal of the electric wire can be automatically inserted into the connector housing (CH1) in the process of manufacturing the sub-harness (Sub1). However, in the process of manufacturing the sub-harness (Sub2), the connector housing (CH1) does not exist on the sub-harness (Sub2) side, and the terminal of the electric wire is not inserted into the connector housing (CH1). Manufactured in a bare state.

  It is very difficult to automatically insert the terminal of the sub-harness (Sub2) as described above into the connector housing (CH1) of the sub-harness (Sub1) manufactured in another line. Therefore, in such a case, a post-fitting correspondence (hereinafter referred to as “rear fitting”), which is a manual work process, is added, and the terminals of the remaining wires of the sub-harness (Sub2) are sub-fitted by the rear fitting ( It must be inserted into the connector housing (CH1) of Sub1).

  Therefore, for example, when trying to manufacture a wire harness with an optimal configuration with the minimum number of parts in accordance with the required specifications of various optional electrical equipment of the user who purchases the vehicle, the number of manual processes increases, If the process is changed, the manufacturing cost is increased.

  The present invention has been made in view of the above-described circumstances, and its object is to manufacture a wire harness that is useful for suppressing an increase in manufacturing cost when manufacturing a wire harness having various configurations according to various required specifications. A method and a wire harness manufacturing apparatus are provided.

In order to achieve the above-described object, the wire harness manufacturing method according to the present invention is characterized by the following (1) to (4).
(1) A wire harness manufacturing method for forming a wire harness that combines a base harness structure that satisfies a predetermined basic specification and one or more optional harness structures that satisfy a condition of selectable option specifications,
According to the content of the order information received from the user, after specifying the specifications of the base harness structure and the specifications of one or more optional harness structures,
Extract the common circuit configuration included in the specifications of the optional harness structure,
Incorporating the extracted common circuit into the specifications of the base harness structure,
Delete the configuration of the common circuit from the specifications of the optional harness structure,
Based on the specifications of the base harness structure in which the common circuit is incorporated and the specifications of the optional harness structure from which the common circuit is deleted, a wire harness according to the content of the order information is manufactured.
It is characterized by that.
(2) The wire harness manufacturing method according to (1) above,
For each option harness structure of an optional specification that can be selected by the user, use a common circuit database that holds data representing at least a division between the common circuit determined in advance and other non-common circuits.
It is characterized by that.
(3) The wire harness manufacturing method according to (1) or (2) above,
Of the circuits included in the specifications of each optional harness structure, at least one of a power line and a ground line is assigned as the common circuit.
It is characterized by that.
(4) The wire harness manufacturing method according to (3) above,
When the circuit included in the specification of each optional harness structure includes a power supply line and a ground line, and the path through which the circuit passes is different from the specification of the base harness structure, the power supply line and the ground line are connected to the common circuit. Exclude from
It is characterized by that.

According to the method of manufacturing the wire harness having the configuration (1), the number of terminals to be fitted later can be reduced, so that the number of manual steps can be reduced and the manufacturing cost can be reduced. For example, various electrical equipment mounted on a vehicle as a basic specification or various electrical equipment added as an option selected by a user usually need to be connected with a power line or a ground line for supplying power. . In many cases, power supply lines and ground lines connected to basic specification electrical equipment and optional specification electrical equipment are connected to a common power supply device on the vehicle via a common connector. Accordingly, when such a power supply line or ground line is assigned as the common circuit, the common circuit is incorporated into the specification of the base harness structure, and the configuration of the common circuit is deleted from the specification of the optional harness structure. As a result, when manufacturing the base harness structure, the terminals of the common circuit can be automatically inserted into the common connector, and the number of terminals to be fitted later can be reduced.
According to the method of manufacturing the wire harness having the configuration (2), the common circuit and the non-common circuit of the optional harness structure can be automatically distinguished by using the common circuit database. It is possible to easily automate the creation of the specifications of the base harness structure in which a circuit is incorporated and the specifications of the optional harness structure from which the common circuit is deleted.
According to the method of manufacturing the wire harness having the configuration (3), the number of terminals to be fitted later can be effectively reduced. That is, the power line and the ground line that are common to various electrical equipment are often connected to a common power source via the same common connector as the electrical equipment of the basic specification. By incorporating it into the base harness structure, the number of terminals that do not require a post-fit process is increased.
According to the wire harness manufacturing method having the configuration (4), it is possible to reduce the number of terminals to be fitted later. That is, even if the power line and the ground line included in the optional harness structure pass through a different path from the base harness structure, the power line and the ground line are connected via a connector different from the base harness structure. Since there is a high possibility of being connected, there is a high possibility that the number of terminals that do not require a post-fit process will increase if the base harness structure is not incorporated.

In order to achieve the above-described object, the wire harness manufacturing apparatus according to the present invention is characterized by the following (5).
(5) A wire harness manufacturing apparatus for forming a wire harness that combines a base harness structure that satisfies a predetermined basic specification and one or more optional harness structures that satisfy a condition of selectable option specifications,

Extract the common circuit configuration included in the specifications of the optional harness structure,
Incorporating the extracted common circuit into the specifications of the base harness structure,
Delete the configuration of the common circuit from the specifications of the optional harness structure,
A manufacturing information generating unit that generates manufacturing specification information including specifications of the base harness structure in which the common circuit is incorporated and specifications of the optional harness structure in which the common circuit is deleted;
A wire harness corresponding to the content of the order information is manufactured based on the manufacturing specification information.

  According to the wire harness manufacturing apparatus having the configuration (5), it is possible to automatically generate the manufacturing specification information having an optimized configuration capable of reducing the number of terminals to be fitted later.

  According to the wire harness manufacturing method and the wire harness manufacturing apparatus of the present invention, an increase in manufacturing cost can be effectively suppressed when manufacturing wire harnesses having various configurations according to various user-specific specifications.

  The present invention has been briefly described above. Further, the details of the present invention will be further clarified by reading through a mode for carrying out the invention described below (hereinafter referred to as “embodiment”) with reference to the accompanying drawings. .

  Specific embodiments of the wire harness manufacturing method and the wire harness manufacturing apparatus of the present invention will be described below with reference to the drawings.

<Outline of wire harness>
In order to facilitate understanding of the present invention, an outline of a general wire harness configuration will be described first.

  A wire harness mounted on a vehicle is used, for example, to connect between a power source on the vehicle and various electrical devices on the vehicle, or to electrically connect between electrical devices, and is included in the wire harness. Each of the many electric wires is used for supplying electric power to various electric devices and transmitting various signals. In addition, since various electrical devices are mounted at various positions on the vehicle, the wire harness has a complicated structure and can be passed through a route specified according to the structure and specifications of the vehicle. It is formed. In addition, a connection terminal is fixed to each tip of a large number of electric wires included in the wire harness by crimping, and the terminal of each electric wire is inserted into the cavity of the connector housing. That is, since the connector is attached to the end of the wire harness, the wire harness can be connected to the target electrical device through the connector. A number of connectors are added to a general wire harness so that it can be connected to various electrical devices.

  Moreover, regarding the wire harness used for a vehicle, for example, it is generally configured as an assembly in which a plurality of sub-harnesses prepared for each system are bundled. The sub-harness to be bundled differs depending on the specifications required for the wire harness.

<Configuration change of wire harness corresponding to user's order contents>
The order contents when the user purchases a vehicle can include selection information of various options.

  Specifically, vehicle model selection, grade (highest grade, speed model, low-priced grade, etc.) selection, region (right steering wheel, left steering wheel classification, etc.), engine specifications (gasoline engine, hybrid model, diesel engine) Option specification indicating the presence / absence of various other optional functions and the types of optional functions, etc., as well as selection of transmission specifications (AT, CVT classification, etc.) Can be included in the order content.

  On the other hand, in order to reduce the manufacturing cost of the wire harness, it is necessary to suppress the number of wires and the number of connectors, which are parts constituting the wire harness, to the minimum necessary according to the product specifications, which is discarded. It is necessary to reduce the number of parts. Therefore, a manufacturer that manufactures a wire harness needs to manufacture a wire harness having an optimum configuration in accordance with the order contents of the user, and is required to change the manufacturing process of the wire harness each time.

  However, there are so many options of option specifications, for example, about 100 types, so when considering all combinations of presence / absence of these, the number and types of wire harnesses increase to a huge number, and management and manufacturing are difficult. It becomes difficult.

  Therefore, the configuration of the wire harness is usually specified by a method as shown in FIG. For example, when the wire harness 41 shown in FIG. 15 is configured, basic components having high commonality in the configuration of the wire harness 41 are configured as the base harness structure 41a, and other components are optional harnesses. The structure 41b and the optional harness structure 41c are respectively configured. And the wire harness 41 is comprised by uniting the base harness structure 41a and the option harness structures 41b and 41c.

  When the wire harness 42 shown in FIG. 15 is configured, a base harness structure 42a, an option harness structure 42b, and an option harness structure 42c are configured, and these are combined to form the wire harness 42. Configure the whole.

  For the basic components of the wire harness, for example, the configuration is specified as a base harness having a common configuration for each group having the same specifications such as a right handle / left handle classification, an engine specification classification, and a transmission specification classification. . A plurality of types of base harnesses are prepared in advance according to the differences in specifications such as the right handle / left handle classification, the engine specification classification, and the transmission specification classification.

  In addition to the basic components described above, an optional harness is prepared for each type of option. For example, a large number of optional harnesses having different configurations are prepared for each function (equipment for in-vehicle electrical equipment) such as an audio function, an air conditioner function, a heater function, a sunroof function, and an electric seat function.

  Moreover, about said base harness, it comprises as an aggregate | assembly which bundled several sub harness (base sub harness). The optional harness is composed of one or more sub-harnesses (optional sub-harness). Each sub-harness includes a relatively small number of electric wires and connectors connected to them.

  The base sub list table 43 shown in FIG. 15 is a list of information that can specify the correspondence between basic order information and a plurality of types of base harnesses, and the configuration of a plurality of base sub harnesses constituting each base harness. Holding. Also, the option sub list table 44 shown in FIG. 15 holds a list of information that can specify the configuration of the option sub harness corresponding to each order information that can be selected as an option.

  Based on the order information generated by the user order, the contents of the wire harness product specification list table 45 shown in FIG. 15 can be specified. And according to the content of the wire harness product specification list table 45, each structure of the wire harness 41 and the wire harness 42 can be specified.

  For example, if the order information of “order 1” is the content for selecting “base 1”, “option A”, and “option D”, the base harness structure 41a is based on the base sub-list table 43. The configuration of the option harness structures 41b and 41c is specified based on the option sub list table 44, and the wire harness 41 can be manufactured using the configuration data obtained as a result of these.

  Further, when the order information of “order 2” is a content for selecting “base 2”, “option B”, and “option C”, the base harness structure 42a is based on the base sub-list table 43. The configuration is specified, the configurations of 42b and 42c are specified based on the option sub-list table 44, and the wire harness 42 can be manufactured using the configuration data obtained as a result of these.

<Major factors of wire harness manufacturing cost increase>
When the wire harness 41 or 42 shown in FIG. 15 is configured, for example, the sub-harness sub01 and the sub-harness sub02 shown in FIG. 2 may be included. In FIG. 2, sub-harness sub01 corresponds to a basic component having a high commonality, that is, a component of base harness structures 41a and 42a in FIG. 15, and sub-harness sub02 is a highly selective component, that is, an option It corresponds to the harness structure 41b, 41c, 42b, or 42c.

  Moreover, about the subharness sub01 shown in FIG. 2, the subharness containing the power wire and earth wire which are contained in a base harness structure can be assumed. The sub-harness sub01 shown in FIG. 2 includes two electric wires, terminals (TM11, TM12, etc.) crimped to each end of each electric wire, connectors (connector housings) CN11 and CN12 into which the respective terminals are inserted, It consists of

  On the other hand, the sub-harness sub02 shown in FIG. 2 includes six electric wires, terminals (TM21, TM22, etc.) crimped to ends of the electric wires, and connectors (connector housings) CN21, CN22 into which the terminals are inserted. It consists of CN23 and CN24.

  Since most of the various on-vehicle electrical devices require power supply from the vehicle side, most of the various optional harness structures include not only the base harness structure but also the power line and the ground line. Therefore, the optional sub-harness sub02 shown in FIG. 2 also includes a power supply line and a ground line as the common circuit sub02a.

  Further, when connecting a power supply box (not shown) for supplying power from the vehicle side to the connector CN12 of FIG. 2, power is also supplied to the optional electrical equipment via the connector CN12. Likely to do. Therefore, the common circuit sub02a of the sub-harness sub02 may be connected to the connector CN12.

  However, the structure of a wire harness is complicated, and it is formed into various shapes according to the required routing route. Therefore, the entire wire harness is automatically assembled in the actual manufacturing process of the wire harness. It is difficult. Therefore, after manufacturing various hub harness structures which are intermediate structures as components of the wire harness in advance, the wire harness is formed by assembling a plurality of hub harness structures in the wiring process.

  That is, after the sub-harness sub01 and the sub-harness sub02 shown in FIG. 2 are manufactured independently, they are combined in the wiring process. Here, since each of the sub-harness sub01 and the sub-harness sub02 has a relatively simple configuration, it can be automatically manufactured. In other words, each manufacturing process, such as cutting the required number and length of wires, crimping the terminals to each wire, and inserting the terminals of the wires with terminals into the connector housing, can be done without using manual manufacturing equipment. It can be carried out.

  However, since the connector CN12 into which the terminals TM21 and TM22 included in the subharness sub02 shown in FIG. 2 are attached is on the side of another subharness sub01, when manufacturing the intermediate structure of the subharness sub02, The terminals TM21 and TM22 cannot be automatically inserted into the connector CN12. Therefore, in this case, after the intermediate structures of the sub-harnesses sub01 and sub02 are manufactured, it is necessary to insert the terminals TM21 and TM22 into the connector CN12 as “rear fitting”.

  However, when the intermediate structures of the plurality of sub-harnesses are manufactured and then combined, it is difficult to automate the work process because the structure and shape are complicated. Therefore, when inserting the terminals TM21 and TM22 into the connector CN12 by “rear fitting”, the work must be performed manually.

  In other words, as the number of user-selectable options increases and the number of optional sub-harnesses included in the product wiring harness increases, the number of optional sub-harnesses that require a back-fitting process and the number of terminals that require rear-fitting Since the number increases, the number of man-hours for the manual manufacturing process increases. Along with this, the labor costs of workers and the costs of various facilities necessary for manufacturing are expected to increase significantly.

  Also, in the case of manual work, the possibility of human error must be taken into account, and when inserting a terminal at the wrong position when inserting a terminal, the predetermined connection function A defective product (miswiring) wire harness will not be manufactured. Therefore, it is necessary to reduce the man-hours for manual work in order to reduce the probability of occurrence of defective products.

<Description of characteristic manufacturing method>
The specific example of the process sequence in embodiment of the wire harness manufacturing method of this invention is shown in FIG. That is, when the order contents of the user are determined and a wire harness having an optimal configuration according to the order contents of the user is manufactured by the manufacturer, the process shown in FIG. Create the data needed to manufacture the harness. Further, the processing shown in FIG. 1 can be automatically performed by installing a predetermined program in a computer that manages the manufacture of the wire harness and executing it.

  In step S11 of FIG. 1, the order information determined by the user is input. This order information includes information on the vehicle type, vehicle grade, region, version, and various optional specifications.

  In step S12, the configuration of the base harness BH that is a part of the wire harness is specified based on the order information input in S11 and the contents of the base harness configuration database DB1.

  A combination of a plurality of types of base circuits and a plurality of types of optional circuits is shown in FIG. That is, the base harness constituting the wire harness has various types of base circuits BC depending on the specifications, and each option harness constituting the wire harness has the presence and type of each electrical equipment selected as an option. There is an optional circuit OC with a combination of corresponding configurations.

  On the base harness configuration database DB1, data representing the configuration for each specification of the various base circuits BC shown in FIG. 6 is registered in advance. In the example of FIG. 6, eight types of base harness configuration data are registered.

  That is, the base circuit BC shown in FIG. 6 is classified based on four types of “common circuit (base)”, two types of “vehicle type”, two types of “path difference”, and “equipment presence / absence”. And 8 types of base harness configuration data. Here, the “common circuit” represents a configuration having a small dependence on specifications in the base circuit BC, and is a circuit corresponding to, for example, a power supply line, a ground line, or the like. “Vehicle type” corresponds to a circuit added in accordance with a classification between a general vehicle type (CONV) and a hybrid vehicle (HV). The “path difference” corresponds to a circuit that is added according to the classification of electric tilt (steering attitude adjustment) and manual tilt. “Equipment presence / absence” corresponds to a circuit added according to the presence / absence of “raindrop sensor”.

  Accordingly, when the “vehicle type”, “route difference”, and “equipment presence / absence” in FIG. 6 are determined from the order information, one of the eight types of base harness configuration data on the base harness configuration database DB1 is S12. It is specified as the configuration of BH. The base harness BH is normally configured as a set of a plurality of sub harnesses. Each sub-harness is configured, for example, as a sub-harness sub01 shown in FIG.

  In step S13 of FIG. 1, the configuration of the option harness OH that is a part of the wire harness is specified based on the order information input in S11 and the contents of the option harness configuration database DB2.

  On the option harness configuration database DB2, data representing the configuration for each specification of the various option circuits OC shown in FIG. 6 is registered in advance. Specifically, the following option circuit OC data is registered as options of various options that can be selected by the user. That is, presence / absence and type of audio (Audio) (A, B, C, D), presence / absence and type of air conditioner (A / C) (A, B, C, D), presence / absence and type of navigation device (Navi) ( A number of optional harness configuration data corresponding to A, B, C, D),... Are registered. For the optional circuit OC, for example, data corresponding to the common circuit sub02a in the subharness sub02 shown in FIG. 2 is represented by “base sub 1”, “base sub 2”, “base sub 3” in FIG. As “base sub 4”,...

  The types “A”, “B”, and “C” of the option circuit OC for the audio equipment respectively correspond to configurations such as option harnesses 11A, 11B, and 11C shown in FIG. 4, for example. Further, the types “A”, “B”, and “C” of the option circuit OC for the air conditioner respectively correspond to configurations such as option harnesses 12X, 12Y, and 12Z shown in FIG.

  That is, one of the option harnesses 11A, 11B, and 11C is selected according to the type of the audio device of the option specification selected by the user, or the option harness 12X, 12Y is selected according to the type of the air conditioner of the option specification selected by the user. , 12Z, etc. are selected. And the structure of the optional harness OH added besides the base harness BH is specified by S13.

  However, when the base harness BH determined in S12 and the optional harness OH determined in S13 are separately manufactured as independent intermediate structures, the sub-harness sub01 and the sub-harness sub02 shown in FIG. As in the case of manufacturing each, a process of manually “retracting” the terminals is required. In order to reduce this “rear fitting” process, the processes after S14 are executed.

  In step S14, the common circuit CC in the optional harness OH specified in S13 is extracted. This common circuit CC corresponds to, for example, the location of the common circuit sub02a in the subharness sub02 shown in FIG. 2, and the “base sub 1” of the option circuit OC shown in FIG. “Base sub 2”, “Base sub 3”, “Base sub 4”,... Therefore, the part previously designated as the common circuit CC is extracted in S14 from the data of the optional harness OH specified in S13.

  In step S15, the configuration of the common circuit CC extracted in S14 is incorporated into the configuration of the base harness BH specified in S12. For example, assuming that the base harness BH identified in S12 includes the sub-harness sub01 in FIG. 2 and the optional harness OH identified in S13 includes the sub-harness sub02 in FIG. By integrating the circuit sub02a with the subharness sub01, the configuration of the subharness sub01B shown in FIG. 3 is generated.

  In step S16, the configuration of the common circuit CC extracted in S14 is deleted from the configuration of the optional harness OH specified in S13. For example, assuming that the base harness BH identified in S12 includes the sub-harness sub01 in FIG. 2 and the optional harness OH identified in S13 includes the sub-harness sub02 in FIG. By deleting the circuit sub02a, the configuration of the sub-harness sub02B shown in FIG. 3 is generated.

  When the processes of S14 to S16 are completed for all the optional harnesses OH specified in S13, the process proceeds to S17.

  In step S17, the configuration of the base harness BH identified in S12 is changed to the configuration after incorporating (adding) the common circuit CC in S15, and the configuration of each optional harness OH identified in S13 is changed to the common circuit in S16. The configuration is changed to the configuration after deleting the CC, and manufacturing specification information including the changed base harness BH and the changed optional harness OH is created. This manufacturing specification information is registered in the manufacturing specification information database DB3 and used in the actual manufacturing process of the wire harness.

<Outline of actual wire harness manufacturing process>
Based on the manufacturing specification information registered in the manufacturing specification information database DB3, each base subharness that is a component of the specified base harness BH and an optional subharness corresponding to the specified option are manufactured. . Since the manufacturing is executed in accordance with the manufacturing specification information on the manufacturing specification information database DB3 generated by the processing of FIG. 1, the base sub-harness actually manufactured as the intermediate structure includes the common circuit CC on the option side. Yes. Further, the optional sub-harness actually manufactured does not include the common circuit CC. That is, for example, the sub-harness sub01B incorporating the common circuit as shown in FIG. 3 and the sub-harness sub02B having the common circuit reduced are manufactured.

  When manufacturing each sub-harness sub01B, sub02B, etc., the necessary number of parts such as electric wires, terminals, connectors, etc., which are the respective constituent elements, are prepared, and the electric wires are cut to a required length. Furthermore, a terminal is attached to each end of each electric wire by crimping. Next, the terminal of each electric wire to which the terminal is added is inserted into the designated cavity position of the connector housing. Since the manufacturing process of such a sub-harness can be performed by an automated manufacturing facility, manual work is unnecessary. For example, in the process of manufacturing the intermediate structure of each sub-harness by reassembling the configuration of each sub-harness shown in FIG. 2 to the configuration shown in FIG. 3, for example, each terminal TM21, TM22 in FIG. The insertion process does not need to be “rear fitting”, and the number of manual processes is reduced.

  Each base sub-harness and each optional sub-harness, which are intermediate structures manufactured as described above, are transported by being placed on a conveyor provided in the production line, and are put into a place on the wiring board. And after adjusting each shape so that it may correspond with the routing route designated beforehand, the aggregate | assembly which laminated | stacked all the sub harnesses is formed as a wire harness.

  However, for example, when a plurality of independent sub-harnesses share one common connector housing, when manufacturing an intermediate structure of some sub-harnesses, some circuits (wires) The terminal cannot be inserted. Therefore, in that case, after manufacturing the corresponding sub-harness, the terminals must be manually inserted into the connector housing as a post-fit. However, by executing the process of FIG. 1, the common circuit CC of the selected optional sub-harness can be incorporated on the base harness side before manufacturing, so that the post-fitting process is greatly reduced in the actual manufacturing process. Is possible.

  The wire harness manufacturing apparatus of the present invention executes the processing procedure as shown in FIG. 1 on various types of computers, for example, and the configuration of data to be handled before actual manufacture is as shown in FIG. It can be realized by automatically rearranging the configuration as shown in FIG. Therefore, the main components of the wire harness manufacturing apparatus can be realized as software.

The five wires AA01 to AA05 are assigned in advance as “common circuits”, and the wire AA08 is assigned as “base subcircuit” in advance.

  Specifically, the option circuit configuration data 15B is wiring necessary for connecting an automatic (AUTO) air conditioner that can be selected by the user as an option. In addition to the data of the option circuit configuration data 15A, two wires represented by numbers AA06 and AA07 are added to the option circuit configuration data 15B. Each of the wire numbered AA06 and the wire numbered AA07 is provided for connection from the air conditioner unit (UNIT) to the sensor (SENSOR). The added numbers AA06 and AA07 are pre-assigned as “optional circuits”. Other than that, it is the same as the optional circuit configuration data 15A.

  The optional circuit configuration data 16A is wiring necessary for connecting a 4-speaker (4SP) audio device (AUDIO) selectable by the user as an option. The optional circuit configuration data 16A includes six electric wires represented by numbers SP01, SP02, SP03, SP04, SP05, and SP06, respectively. The number SP01 wire is provided to connect the power supply box to the power supply terminal of the audio device connector, and the number SP02 wire is provided to connect from the “common ground” to the audio device connector ground terminal. Yes. The wires SP03 and SP04 are provided to connect the two terminals of the front right speaker (FR SP RH) to the right speaker output terminals (two) of the connector of the audio device. Similarly, the wires SP05 and SP06 are provided to connect the two terminals of the front left speaker (FR SP LH) to the left speaker output terminals (two) of the connector of the audio device.

The electric wires with numbers SP07 to SP10 are assigned in advance as “optional circuits”.

<Specific example of manufacturing without changing the configuration of the common circuit>
FIG. 5 shows a configuration example of the wire harness when the configuration of the common circuit is not changed. That is, among the configuration data shown in FIG. 7, the base circuit configuration data 13 and 14 and the option circuit configuration data 15B and 16B are used, and the four intermediate structures are directly processed without performing the processing of FIG. When a wire harness is configured by combining four intermediate structures, the result is as shown in FIG.

  The base sub-harnesses BSH01 and BSH02 shown in FIG. 5 are intermediate structures corresponding to the base circuit configuration data 13 and the base circuit configuration data 14 of FIG. 7, respectively. The option sub-harnesses OSH01 and OSH02 are intermediate structures corresponding to the option circuit configuration data 15B and the option circuit configuration data 16B in FIG. 7, respectively.

  In the configuration example shown in FIG. 5, it is assumed that the connector PWB for connecting to the power supply box of the vehicle is connected to the base sub harness BSH02 when the intermediate structure of the base sub harness BSH02 is manufactured. . That is, the terminal TM001 attached to the tip of the electric wire number P01 of the base circuit configuration data 13 is inserted into a specific cavity of the connector (connector housing) PWB.

  Therefore, when manufacturing the intermediate structures of the base sub-harness BSH01 and the optional sub-harnesses OSH01 and OSH02, they cannot be connected to the connector PWB. That is, the terminals TM002 and TM003 attached to the ends of the two wires of the base sub harness BSH01, the terminals TM004 and TM005 attached to the ends of the two wires of the option sub harness OSH01, and one of the options sub harness OSH02. The five locations with the terminal TM006 attached to the tip of the electric wire are in a state separated from the connector PWB as an intermediate structure. Therefore, when manufacturing a wire harness by combining four intermediate structures of the base sub-harnesses BSH01 and BSH02 and the optional sub-harnesses OSH01 and OSH02, the terminals TM002, TM003, TM004, TM005, and TM006 are referred to as “rear”. It must be inserted manually into the corresponding cavity of the connector PWB as a “fit”. Further, when the number of options selected by the user increases and the number of intermediate structures of option sub-harnesses constituting the wire harness increases, the number of terminals that require the “rear fitting” process further increases.

<Example of wire harness configuration for each type of order>
FIG. 8 shows a list of wire harness configurations for each type of order (order) of the user when using the data shown in FIG.

  In the example shown in FIG. 8, “order 1” corresponds to the configuration of the wire harness in which the intermediate structures of the base circuit configuration data (METER) 14 and the optional circuit configuration data (MANUAL_AIR_CON) 15A are combined. Yes.

  “Order 2” is a wire harness obtained by combining intermediate structures of base circuit configuration data (METER) 14, option circuit configuration data (MANUAL_AIR_CON) 15A, and option circuit configuration data (AUDIO 4SP) 16A. It corresponds to the configuration of.

  “Order 3” is a wire harness configuration in which the intermediate structures of base circuit configuration data (METER) 14, option circuit configuration data (MANUAL_AIR_CON) 15A, and option circuit configuration data (AUDIO 6SP) 16B are combined. It corresponds to.

  “Order 4” includes base circuit configuration data (METER) 14, base circuit configuration data (POWER SOCKET) 13, optional circuit configuration data (MANUAL_AIR_CON) 15A, and optional circuit configuration data (AUDIO 4SP) 16A. It corresponds to the configuration of the wire harness that combines the intermediate structures.

  “Order 5” includes base circuit configuration data (METER) 14, base circuit configuration data (POWER SOCKET) 13, optional circuit configuration data (MANUAL_AIR_CON) 15A, and optional circuit configuration data (AUDIO 6SP) 16B. It corresponds to the configuration of the wire harness that combines the intermediate structures.

  “Order 6” includes base circuit configuration data (METER) 14, base circuit configuration data (POWER SOCKET) 13, optional circuit configuration data (AUTO_AIR_CON) 15B, and optional circuit configuration data (AUDIO 6SP) 16B. It corresponds to the configuration of the wire harness that combines the intermediate structures.

<Specific example of manufacturing after changing the configuration of the common circuit>
The structure of the wire harness for each order when manufacturing each intermediate structure after changing the configuration of the common circuit by applying the process of FIG. 1 is shown in FIGS. That is, the configuration corresponding to “order 1” in FIG. 8 is shown in FIG. 9, the configuration corresponding to “order 2” is shown in FIG. 10, the configuration corresponding to “order 3” is shown in FIG. A configuration corresponding to “order 4” is shown in FIG. 12, a configuration corresponding to “order 5” is shown in FIG. 13, and a configuration corresponding to “order 6” is shown in FIG.

  The wire harness having the configuration shown in FIG. 9 is a combination of the base sub-harness BSH01 corresponding to the base circuit configuration data 14 of FIG. 7 and the option sub-harness OSH01 corresponding to the option circuit configuration data 15A of FIG.

  However, the wires M01 and M02 are assigned as “common circuits” in the base circuit configuration data 14 shown in FIG. 7, and the wires AA01 and AA02 are also assigned as “common circuits” in the optional circuit configuration data 15A. Therefore, the configuration of the sub-harness is rearranged by the process of FIG. 1 before actual manufacture.

  That is, the terminals TM002 and TM003 of the base sub-harness BSH01 and the terminals TM004 and TM005 of the optional sub-harness OSH01 are an intermediate structure (not shown, FIG. 3) that is a constituent element of the base harness. (Equivalent to sub01B in the middle) is incorporated into this common sub-harness. In addition, since the two wires of the base circuit configuration data (POWER SOCKET) 13 that is pre-designated to be “first-fitted” to the connector PWB for the power supply hox are designated as the same “common circuit”, When manufacturing the intermediate structure of the common sub-harness, the terminals TM002, TM003, TM004, and TM005 are all connectable to the connector PWB. Therefore, when the wire harness having the configuration shown in FIG. 9 is manufactured, the number of places where “rear fitting” is necessary is zero.

  On the other hand, the wire harness having the configuration shown in FIG. 10 includes a base sub-harness BSH01 corresponding to the base circuit configuration data 14 shown in FIG. 7, an option sub-harness OSH01 corresponding to the option circuit configuration data 15A shown in FIG. This is a combination with an optional sub-harness OSH02 corresponding to 16A.

  However, as in the case of the configuration of FIG. 9 described above, the terminals TM002, TM003, TM004, and TM005 belong to the “common circuit”, and therefore, when the intermediate structure of the common sub-harness is manufactured, the terminals TM002 are provided. , TM003, TM004, and TM005 are all “front-fitted” to the connector PWB for the power supply hocks.

  On the other hand, in the optional circuit configuration data 16A shown in FIG. 7, the wires SP01 and SP02 are designated as “base subcircuits” and are not “common circuits”. Therefore, an intermediate structure different from the common subharness is used. Manufactured as. Therefore, the terminal TM006 of the option sub-harness OSH02 must be inserted into the connector PWB by “rear fitting”. Therefore, when manufacturing the wire harness having the configuration shown in FIG. 10, manual “rear fitting” is required only at one location of the terminal TM006.

  11 includes a base sub-harness BSH01 corresponding to the base circuit configuration data 14 in FIG. 7, an option sub-harness OSH01 corresponding to the option circuit configuration data 15A in FIG. 7, and the option circuit configuration data 16B. This is a combination with the corresponding optional sub-harness OSH02.

  However, as in the case of the configuration of FIG. 9 and FIG. 10 described above, the terminals TM002, TM003, TM004, and TM005 belong to the “common circuit”. Therefore, when manufacturing the intermediate structure of the common subharness, Each of the terminals TM002, TM003, TM004, and TM005 is “first-fitted” to the power supply hook connector PWB.

  On the other hand, in the optional circuit configuration data 16B shown in FIG. 7, the wires SP01 and SP02 are designated as “base subcircuits” and are not “common circuits”. Therefore, an intermediate structure different from the common subharness is used. Manufactured as. Therefore, the terminal TM006 of the option sub-harness OSH02 must be inserted into the connector PWB by “rear fitting”. Therefore, when manufacturing the wire harness having the configuration shown in FIG. 11, “rear fitting” by manual work is required only at one location of the terminal TM006.

  12 includes a base sub-harness BSH01 corresponding to the base circuit configuration data 14 in FIG. 7, a base sub-harness BSH02 corresponding to the base circuit configuration data 13, and the optional circuit configuration data 15A in FIG. This is a combination of a corresponding option sub-harness OSH01 and an option sub-harness OSH02 corresponding to the option circuit configuration data 16A.

  However, as in the case of the configuration of FIG. 9 described above, since the terminals TM002, TM003, TM004, and TM005 belong to the “common circuit”, an intermediate structure of the common subharness including the base subharness BSH02 is manufactured. At this time, the terminals TM002, TM003, TM004, and TM005 are all “front-fitted” to the connector PWB for the power supply hocks.

  Further, in the optional circuit configuration data 16A, the wires SP01 and SP02 are designated as “base subcircuits” and are not “common circuits”, so these wires are intermediate structures different from the common subharness. Manufactured as. Therefore, the terminal TM006 of the option sub-harness OSH02 must be inserted into the connector PWB by “rear fitting”. Therefore, when manufacturing the wire harness having the configuration shown in FIG. 12, “rear fitting” by manual work is required only at one location of the terminal TM006.

  The wire harness having the configuration shown in FIG. 13 includes a base sub-harness BSH01 corresponding to the base circuit configuration data 14 in FIG. 7, a base sub-harness BSH02 corresponding to the base circuit configuration data 13, and the optional circuit configuration data 15A in FIG. This is a combination of a corresponding option sub-harness OSH01 and an option sub-harness OSH02 corresponding to the option circuit configuration data 16B.

  However, as in the case of the configuration of FIG. 9 described above, since the terminals TM002, TM003, TM004, and TM005 belong to the “common circuit”, an intermediate structure of the common subharness including the base subharness BSH02 is manufactured. At this time, the terminals TM002, TM003, TM004, and TM005 are all “front-fitted” to the connector PWB for the power supply hocks.

  Further, in the optional circuit configuration data 16B, the wires SP01 and SP02 are designated as “base subcircuits” and are not “common circuits”, so these wires are intermediate structures different from the common subharness. Manufactured as. Therefore, the terminal TM006 of the option sub-harness OSH02 must be inserted into the connector PWB by “rear fitting”. For this reason, when manufacturing the wire harness having the configuration shown in FIG. 13, manual “rear fitting” is required only at one location of the terminal TM006.

  The wire harness having the configuration shown in FIG. 14 includes a base sub-harness BSH01 corresponding to the base circuit configuration data 14 in FIG. 7, a base sub-harness BSH02 corresponding to the base circuit configuration data 13, and the optional circuit configuration data 15B in FIG. This is a combination of a corresponding option sub-harness OSH01 and an option sub-harness OSH02 corresponding to the option circuit configuration data 16B.

  However, as in the case of the configuration of FIG. 9 described above, since the terminals TM002, TM003, TM004, and TM005 belong to the “common circuit”, an intermediate structure of the common subharness including the base subharness BSH02 is manufactured. At this time, the terminals TM002, TM003, TM004, and TM005 are all “front-fitted” to the connector PWB for the power supply hocks.

  Further, in the optional circuit configuration data 16B, the wires SP01 and SP02 are designated as “base subcircuits” and are not “common circuits”, so these wires are intermediate structures different from the common subharness. Manufactured as. Therefore, the terminal TM006 of the option sub-harness OSH02 must be inserted into the connector PWB by “rear fitting”. Therefore, when manufacturing the wire harness having the configuration shown in FIG. 14, manual “rear fitting” is required only at one location of the terminal TM006.

<Explanation of reduction of post-fitting process by rearranging common circuits>
If the wire harness is manufactured without executing the processing shown in FIG. 1, it is necessary to manually “retract” the five terminals, for example, as shown in FIG. An increase in cost is inevitable.

  On the other hand, when the wiring harness is manufactured after the common circuit CC is rearranged by executing the processing shown in FIG. 1, the “order 1”, “order 2”, “order” shown in FIG. 9, 10, 11, 12, 13, and 14 for each of “3”, “order 4”, “order 5”, and “order 6”. Will be manufactured.

  That is, even in the case of manufacturing the wire harness of any configuration of FIGS. 9, 10, 11, 12, 13, and 14, since “rear fitting” is only 0 or 1 place, Compared with the case where the wire harness shown in FIG. 5 is manufactured, the number of steps of “rear fitting” can be greatly reduced.

<Method for determining common circuit CC>
For the common circuit CC, for example, it is determined in advance whether each electric wire constituting each sub-harness is a “common circuit”, such as each data 13, 14, 15A, 15B, 16A, and 16B shown in FIG. Information indicating the determined contents is registered in advance in the base harness configuration database DB1 and the option harness configuration database DB2 shown in FIG. Therefore, by executing the processing of FIG. 1, the configuration of the intermediate structure can be automatically rearranged before manufacture so that the “common circuit” is incorporated in the sub-harness in the base harness.

  Here, for example, it is assumed that three types of optional harnesses 11A, 11B, and 11C for audio equipment shown in FIG. 4 are selectively manufactured. When these optional harnesses 11A, 11B, and 11C include a power line and a ground line that can be easily shared, and these are configured to pass through a wiring route that is substantially common to the base harness, these Can be assigned as a “common circuit”.

  On the other hand, assuming that the three types of optional harnesses 12X, 12Y, and 12Z for the air conditioner shown in FIG. 4 are selectively manufactured, the routing paths of the optional harnesses 12X, 12Y, and 12Z are greatly different from each other. Therefore, even if these include a power supply line and a ground line, they are assigned to be excluded from the “common circuit”.

  Regarding the work of determining whether or not each electric wire of each sub-harness registered in DB1 and DB2 corresponds to a "common circuit", it is assumed that the designer performs it manually, but based on various data It is not impossible to determine automatically.
