Description

  The present invention relates to an automatic generation method of sub-harness configuration information for separating a wire harness into a plurality of appropriate sub-harness configurations and automatically generating configuration information of each sub-harness configuration, and a program for causing a computer to execute the method. .

  Conventionally, for example, a wire harness incorporated in a vehicle is a complex assembly of 300 to 600 circuits. Therefore, when assembling the wire harness, for example, it is divided into 10 to 50 appropriate sub-harness components, and the sub-harness configuration is assembled. As a result, the number of assembly steps can be leveled.

  Here, in the production preparation of subdividing the wire harness into sub-harness configurations, the actual wire harness is disassembled, and an appropriate sub-harness configuration is determined by human skilled work. For this reason, the production preparation of subdividing into sub-harness configurations takes a lot of time and labor, and there is a problem that it takes a total manufacturing time of the wire harness.

  For this reason, the CAD form development data of the wire harness is used, this CAD form development data is developed on the computer, the sub-harness configuration is simulated manually, and trial and error are repeated to finally determine a plurality of sub-harness configurations. A system was developed. As a result, the time required for trial and error in determining the sub-harness configuration can be shortened, and the time can be reduced by about 40% as compared with the case where the sub-harness configuration is determined by actual decomposition (see Patent Document 1).

JP 11-339572 A

  However, even in the above-described simulation using manual CAD, the final determination of the sub-harness configuration involves human judgment, so that there is still a problem that it takes time for production preparation. In addition, since human judgment is involved, there is a problem in that the suitability of the sub-harness configuration determined by the person's ability varies.

  Moreover, because the number of circuits in the appropriate sub-harness configuration unit differs between the assembly using the in-line method and the assembly using the offline method, it is very difficult to determine the sub-harness configuration suitable for each method. There was a problem that it took time.

  The present invention has been made in view of the above, and a sub-harness configuration that can always determine a sub-harness configuration having an optimal number of circuits in a short time in order to eliminate the above-described problems caused by the prior art An object is to provide a method for automatically generating information and a program for causing a computer to execute the method.

In order to solve the above-described problems and achieve the object, an automatic generation method of sub-harness configuration information according to the present invention separates a wire harness into a plurality of sub-harness configurations and automatically generates configuration information of each sub-harness configuration. In the automatic generation method of sub-harness configuration information, the computer acquires an overall configuration information of the wire harness, and the computer has a predetermined number of circuits connected to the coupler among the couplers constituting the wire harness.

According to this invention, when separating the wire harness into a plurality of sub-harness configurations and automatically generating the configuration information of each sub-harness configuration, the computer acquires the overall configuration information of the wire harness such as CAD form development data , wherein among the coupler constituting a wire harness, the number of circuits connected to the coupler to prioritize each coupler in descending order of a to the number of circuits equal to or less than the predetermined number, selects the highest coupler priority as fog coupler Based on at least the number of circuits of the couplers connected to the selected head coupler in a tree structure and the circuit connection form, the coupler and the circuit connected to the coupler are routed to the sub coupler as the root. It is determined whether or not to include in the harness configuration, a process of determining a sub-harness configuration with the head coupler as a root is performed , and the determined sub-harness is determined The priority order is updated for the couplers other than the configuration, and the process of determining the sub-harness configuration for the undecided couplers and circuits is repeated until there is no head coupler, and finally the sub-harness configuration information is automatically generated. Like to do.

According to the present invention, since the coupler array diagram and the sub wiring diagram necessary for creating each sub-harness are also created, the time required for creating the sub-harness can be further shortened.

Also, in the automatic generation method of sub-harness configuration information according to the present invention, in the above-described invention, the computer outputs the surplus information that is not included in the configuration information of each sub-harness configuration determined in the determination step. The method further includes a step.

According to this invention, since the information leaked from the sub-harness configuration is output, it is possible to reliably create the wire harness.

Also, in the above-described invention, the sub-harness configuration information automatic generation method according to the present invention is the above-described invention, in which the computer is assembled by an automatic device or another process based on the overall configuration information of the wire harness acquired by the acquisition step . The method further includes an exclusion step of excluding the coupler and the circuit from being processed.

Also, in the automatic generation method of sub-harness configuration information according to the present invention, in the above-described invention, in the prioritizing step , the computer has a coupler as a central joint, a coupler as a joint connector, and then the number of circuits to be inserted. A high priority is set in the order of many couplers, and a low priority is set for a joint connector with no circuit insertion location designation.

Moreover, the automatic generation method of the subharness configuration information according to the present invention is the above invention, in which, when the wire harness is assembled by an inline method, the predetermined number of insertion circuits is 5, and the wire harness is assembled by an offline method. The predetermined number of insertion circuits is twenty.

In the automatic generation method of sub-harness configuration information according to the present invention , in the above invention, the determination step includes a selection step of selecting a head coupler having the highest priority, and a child connected to the selected head coupler. When the number of circuits to the head coupler side of the coupler is equal to or greater than the number of circuits to each grandchild coupler side other than the head coupler connected to the child coupler, the sub coupler configuration including the head coupler includes the child coupler.

In the case of a connector, when the number of insertion circuits to the sub coupler or the grand coupler is 100%, it is included in the sub harness configuration.

A program according to the present invention causes a computer to execute the automatic generation method of subharness configuration information described in any one of the above inventions .

  An automatic generation method of sub-harness configuration information according to the present invention and a program for causing a computer to execute the method separates a wire harness into a plurality of sub-harness configurations, and automatically generates configuration information of each sub-harness configuration. Obtains the overall configuration information of the wire harness such as CAD form development data, and the prioritizing step is that the number of circuits connected to the coupler is less than or equal to a predetermined number among the couplers constituting the wire harness. Each coupler is prioritized in order of increasing number, and the determination step selects the coupler having the highest priority as the head coupler, and at least the number and circuit of the couplers connected in a tree structure to the selected head coupler Based on the connection mode, the coupler and the circuit connected to the coupler are routed to the sub coupler with the head coupler as a root. Determining whether or not to include in the nesting configuration, and performing a process of determining a subharness configuration having the head coupler as a root, and the repetition step is performed on the coupler excluding the subharness configuration determined in the determination step. The priority order is updated, and the process of determining the sub-harness configuration for the couplers and circuits that have not been determined in the determination step is repeated until there is no head coupler, and finally the sub-harness configuration information is automatically generated. Therefore, sub-harness configuration information having an optimal number of circuits can always be generated in a short time, and the leveling of labor at the time of manufacturing the wire harness can be promoted.

  In addition, the automatic generation method of sub-harness configuration information according to the present invention and the program that causes the computer to execute the method also create a coupler array diagram and a sub-wiring diagram that are necessary when creating each sub-harness. There is an effect that the time required for creating the sub-harness can be further shortened.

  In addition, the automatic generation method of the sub-harness configuration information and the program for causing the computer to execute the method according to the present invention output the information leaked from the sub-harness configuration, so that the wire harness is reliably created. There is an effect that can be.

  A sub-harness configuration information automatic generation method according to the present invention and a program that causes a computer to execute the method will be described below with reference to the accompanying drawings. FIG. 1 is a diagram for explaining the position occupied by the method for automatically generating subharness configuration information according to the embodiment of the present invention in the entire manufacturing process of a wire harness. In FIG. 1, first, a wire harness 10 to be manufactured mainly includes an electric wire bundle 1 and a coupler 2 which are electric wire (circuit) bundles. The clamp 4 fixes the wire bundle 1 to the vehicle body, and the protective material 5 protects the wire bundle 1. Further, the coupler 2 is usually connected to the end of the circuit, but there is a form in which the coupler 2 is not connected like the terminal 3.

  In order to manufacture this wire harness 10, ASSY FIG. 11 is created after that. ASSY FIG. 11 is a drawing used for an ASSY plate 14 which is an assembly plate for manufacturing a wire harness, and this drawing is created as CAD data. The CAD data shown in FIG. 11 can be said to be one CAD form development data.

  Then, based on this CAD form development data, the sub-harness configuration automatic generation process 12 for subdividing the wire harness 10 into a plurality of sub-harness configurations is performed, and a plurality of sub-harness configurations 13-1 to 13-n (sub-harnesses) A configuration group 13) is generated.

  Thereafter, a plurality of sub-harnesses are manufactured based on the information indicated by the sub-harness configurations 13-1 to 13-n, and the sub-corresponding to the sub-harness configurations 13-1 to 13-n on the ASSY plate 14 are manufactured. The final wire harness 10 is completed by combining the harnesses.

  Therefore, the sub-harness configuration group 13 can be automatically generated only by inputting the CAD form development data, and labor and time can be reduced. In fact, compared with the conventional method in which the actual wire harness is disassembled to determine the sub-harness configuration, the labor is drastically reduced and the time can be shortened by about 75%.

  Here, with reference to the flowchart shown in FIG. 2, an overall processing procedure of the sub-harness configuration information automatic generation method according to the embodiment of the present invention will be described. This process is implemented as a program on a computer and executed. In FIG. 2, first, when this program is executed, CAD form development data which is the entire information of the wire harness is acquired (step S101). Thereafter, it is determined whether or not there is an M sign circuit in the CAD form development data (step S102). The M sign circuit is a coupler or circuit having a code including “M” in the CAD form development data, and is a component separately manufactured by an automatic device such as an automatic sub-ASSY machine. Therefore, the M sine circuit is not included in the sub-harness configuration. For this reason, when there is an M sine circuit (YES in step S102), this M sine circuit is set out of the processing target (step S103), is excluded from the processing thereafter, and the process proceeds to step S104. If not (NO in step S102), the process proceeds to step S104 as it is. In addition, not only the M sine circuit but also the P sine circuit, for example, may be set out of the processing target. This P sine circuit is a closed component part of the airbag system, and this P sine circuit is also produced under another automatic device or under special management, and is therefore excluded from processing. In other words, the determination process in step S102 is for excluding those that are prepared in advance at an automatic device or another manufacturing site, such as a P-sine circuit, from the sub-harness configuration information generation process.

  Thereafter, prioritization of head coupler selection is performed (step S104). The head coupler is a coupler that becomes the root of the tree structure sub-harness configuration including the child coupler and the grandchild coupler. In order to prioritize the head couplers, when assembling the wire harness by the off-line method, if the number of circuit insertions is 20 or less, the head coupler is the target, and when assembling the wire harness by the in-line method, the number of circuit insertions is 5 or less. This is the target of the head coupler. Here, the in-line method is one in which the assembly of the sub-harness configuration is sequentially performed on the belt conveyor to complete the assembly of the entire wire harness, and this method is particularly adopted overseas. The offline method is a method in which the assembly of the sub-harness configuration and the assembly of the entire wire harness are performed separately, and Japan has adopted this method. The reason why the number of circuit insertions targeted for the in-line type head coupler is small is that the time for assembling the sub-harness configuration in the flow work is short. In addition, in the case of a wire harness having 300 to 600 circuits, the sub-harness configuration is optimally 20 to 30 circuits in which the number of circuit insertions that are the target of the head coupler in the offline system is 20 or less. For this purpose, the number of inserted head coupler circuits should be 20 or less.

  The priority order of the head coupler is given in the order of concentrated joint → joint connector → other couplers under the limitation of the number of circuit insertions described above. In other couplers, priorities are given in the order of the number of circuit insertions. In the joint connector, since all the circuits to be inserted are electrically common circuits, the circuit insertion location may be any location. However, when the circuit designation of the circuit insertion location is specified, the priority is set as described above. The priority order is set to a lower value when the circuit insertion position may be an arbitrary position. In addition, prioritization of the head coupler selection is performed again every time a sub-harness configuration is determined. In this case, when some circuits of the coupler are determined, the number of inserted circuits is the number obtained by deleting the determined number. For example, a coupler such as a fuse box may be inserted with 50 to 100 circuits, but the number of inserted circuits decreases as the determination of the sub-harness configuration proceeds and may be adopted as a head coupler.

  Thereafter, it is determined whether there is an unprocessed coupler (step S105). If there is no unprocessed coupler, it means that there is no sub-harness configuration information generation process target, and all the processes have been completed, so a result list is output (step S113), and this process is performed. finish. Here, the result list is surplus information such as a surplus circuit that is not included in the sub-harness configuration. For example, as shown in FIG. 3, if the circuit 23 is M-signed and the circuit 24 is not M-signature among the circuits sandwiched between the M-signed couplers 21 and 22, the circuit 24 is This circuit 24 is a surplus circuit because it is not connected by the above and is not a sub-harness configuration. The circuit 24 is, for example, a joint line, a shield line, or a twist line. Further, as shown in FIG. 4, in this embodiment, a tree-structured sub-harness configuration from the head coupler to the child coupler to the grandchild coupler is determined. In the case of a sub-harness configuration in which the coupler 32 is connected and the grandchild couplers 33 and 34 are connected to the child coupler 32 via the circuits 42 and 43, respectively, and the circuit 44 exists in the grandchild couplers 33 and 34, the circuit 44 is It is not included in the sub-harness configuration and becomes a surplus circuit. Such surplus circuits are listed and output as a result list.

  On the other hand, when there is an unprocessed coupler (step S105, YES), the head coupler with the highest priority is selected (step S106). Thereafter, a sub-coupler inclusion determination process is performed to determine whether or not the sub-coupler connected to the selected head coupler is included in the sub-harness configuration of the head coupler (step S107). This process will be described later.

  Thereafter, it is determined whether or not the selected head coupler is a concentrated joint (step S108). If the head coupler is not a lumped joint (step S108, NO), grandchild circuit determination processing is performed to determine whether or not a grandchild circuit connected to the grandchild circuit side of the child coupler is included in the subharness configuration of the head coupler. (Step S109) Further, grandchild coupler inclusion determination processing for determining whether or not the grandchild coupler connected to the grandchild circuit is included in the sub-harness configuration of the head coupler is performed (step S110). On the other hand, when the head coupler is a lumped joint (step S108, YES), the grandchild coupler inclusion determination process for determining whether or not the grandchild coupler is included in the subharness configuration of the head coupler without performing the grandchild circuit determination process. Is performed (step S110). The grandchild circuit determination process and the grandchild coupler inclusion determination process will be described later.

  Thereafter, the used parts used in one sub-harness configuration determined by the above-described processing are registered in association with this sub-harness configuration (step S111). Further, based on the sub-harness configuration information, a coupler array diagram showing the assembly relationship of the sub-harness configuration and a sub-wiring diagram showing the connection relationship on the ASSY diagram are created (step S112), and the process proceeds to step S104. Then, the above priority selection of the head coupler is performed again, and the next generation process of the sub-harness configuration information is repeated until there is no unprocessed coupler.

  Next, with reference to the flowchart shown in FIG. 5, the sub-coupler inclusion determination process procedure in step S107 will be described. First, since the head coupler is selected, one of the child couplers connected to the head coupler is selected (step S201). Thereafter, it is determined whether or not the selected sub coupler has already been set to another sub-harness configuration (step S202). When the sub coupler is already set to another sub harness configuration (step S202, YES), the sub coupler is excluded from the sub harness configuration (step S208), and the process proceeds to step S209.

  On the other hand, when the selected child coupler is a new child coupler that has not been set to another subharness configuration (step S202, NO), it is further determined whether or not this child coupler is a central joint or a joint connector. (Step S203). If the sub coupler is not a central joint or a joint connector (step S203, NO), the number of circuits for each destination connected to the sub coupler is totaled (step S204), and the destination of the maximum number of circuits is the selected head coupler. Whether or not (step S205). That is, it is determined whether or not the number of circuits connected to the parent coupler among the circuits connected to the child coupler is the largest compared to the circuits connected to other couplers. When the destination of the maximum number of circuits is the selected head coupler (step S205, YES), this child coupler is included in the sub-harness configuration (step S206), and the destination of the maximum number of circuits is not the selected head coupler (Step S205, NO), this child coupler is excluded from the sub-harness configuration (Step S208), and the process proceeds to Step S209.

  On the other hand, if the slave coupler is a concentrated joint or a joint connector in step S203, it is determined whether or not the circuit from the parent coupler is 100% connected to the connection terminal of the slave coupler (step S207). When 100% is connected to the connection terminal of the sub coupler (step S207, YES), this sub coupler is included in the sub-harness configuration (step S206), and is not 100% connected to the connection terminal of the sub coupler (step S206). In step S207, NO), the sub coupler is excluded from the sub-harness configuration (step S208), and the process proceeds to step S209. In this way, the condition of inclusion of child couplers for a lumped joint or joint connector is severe. The lumped joint or joint connector generally has a large number of connection circuits, so the number of circuits in one sub-harness configuration may become too large. Because.

  Thereafter, it is determined whether or not there is a next sub coupler (step S209). If there is a next sub coupler (step S209, YES), the process proceeds to step S201, where the next sub coupler is selected and described above. This process is repeated, and if there is no next sub coupler (step S209, NO), this process ends, and the process returns to step S107.

  Here, an example of the inclusion process of the sub coupler will be described with reference to FIGS. In FIG. 6, the number of circuits between the head coupler 51 and the child coupler 52 is 5, the number of circuits between the child coupler 52 and the grandchild coupler 53 is 1, and between the child coupler 53 and the grandchild coupler 54. Since the number of circuits is 3 and the number of circuits between the head coupler 51 and the slave coupler 52 is the maximum, the slave coupler 52 is included in the sub-harness configuration in the determination of step S205.

  In FIG. 7, the slave coupler 62 is connected to the head coupler 61 by a single circuit, and to the coupler 63 by two circuits, and therefore, between the head coupler 61 and the slave coupler 62. Thus, the number of circuits is not the maximum, and the sub coupler 62 is not included in the sub-harness configuration, and only the circuit 61a is connected to the head coupler. On the other hand, as shown in FIG. 8, when the child coupler 62 is connected to each of the couplers 64 and 65 by one circuit, the number of circuits for the head coupler 61 and each of the couplers 64 and 65 becomes equal. The sub coupler 62 is included in the sub harness configuration. The reason why the inclusion relationship of the sub couplers is determined based on the number of circuits in this way is that the influence of the coupler connected to the sub coupler is taken into account.

  Next, the grandchild circuit determination processing procedure in step S109 will be described with reference to the flowchart shown in FIG. If inclusion of the child coupler is determined in step S107, it is determined whether or not a grandchild circuit between the grandchild coupler connected to the child coupler is included in the subharness configuration unless the head coupler is a lumped joint. Therefore, first, one grandchild circuit for each destination (grandchild coupler) connected to the child coupler is selected (step S301). Thereafter, it is determined whether or not the selected grandchild circuit is a circuit connected to the already determined coupler (step S302).

  If the circuit is connected to the determined coupler (YES in step S302), the grandchild circuit is set to be included in the subharness configuration (step S304), and the process proceeds to step S306. On the other hand, if the circuit is not connected to the determined coupler (NO in step S302), it is determined whether or not the wiring ratio of the grandchild coupler with respect to the child coupler is 100% (step S303). When the wiring ratio is 100% (step S303, YES), the grandchild circuit is set to be included in the sub-harness configuration (step S304), and the process proceeds to step S306. On the other hand, when the wiring ratio is not 100% (step S303, NO), the grandchild circuit is excluded from the sub-harness configuration (step S305), and the process proceeds to step S306.

  Thereafter, it is determined whether or not there is a next grandchild circuit connected to the child coupler (step S306). If there is a grandchild circuit (YES in step S306), the process proceeds to step S301, and the next grandchild circuit is changed. If selected, the above-described processing is repeated, and if there is no grandchild circuit (step S306, NO), this processing ends, and the processing returns to step S109.

  Here, an example of grandchild circuit determination processing will be described with reference to FIG. 10 is the same as the configuration shown in FIG. 6, and the grandchild coupler 53 is connected to the child coupler 52 by one circuit, and the wiring ratio to the child coupler 52 is 100%. Therefore, the circuit 53a is determined as the grandchild circuit. And included in the sub-harness configuration. On the other hand, the grandchild coupler 54 has five circuits, and three circuits are connected to the child coupler 52. Therefore, since the wiring ratio of the coupler (grandchild coupler) 54 is 60%, the circuit 54a is not determined as a grandchild circuit and is not included in the subharness configuration.

  Next, the inclusion determination process procedure of the grandchild coupler in step S110 will be described. This processing procedure is the same as the sub-coupler inclusion determination processing procedure shown in FIG. 5, and the head coupler and the sub-coupler may be replaced with a sub-coupler and a grand-sub-coupler, respectively (see FIG. 11).

  Here, an example of the grandchild coupler inclusion process will be described with reference to FIGS. In FIG. 12, since the grandchild coupler 53 is not a central joint or a joint connector, the grandchild coupler is included in the sub-harness configuration when the number of circuits for each destination is the maximum for the child coupler 52. Since the circuit of the grandchild coupler 53 is only the circuit 53a for the child coupler 52, the grandchild coupler 53 is included in the sub-harness configuration. On the other hand, since the grandchild circuit 54a is excluded from the subharness configuration, the determination process of the grandchild coupler 54 is not performed and is not included in the subharness configuration as a grandchild coupler.

  On the other hand, FIG. 13 shows a case where the grandchild coupler is a lumped joint. In this case, grandchild circuit determination processing is not performed. Here, since the grandchild coupler 63 is 100% connected to the connection terminal at the present time, it becomes a problem whether or not the number of circuits for each destination is the maximum with respect to the child coupler 62. Here, since the grandchild coupler 63 has 50% of the number of circuits relative to the child coupler 62, it is included in the subharness configuration as a grandchild coupler, and the circuit 62a is also included in the subharness configuration as the grandchild circuit 62a. However, the already determined circuit 63a is not included in the sub-harness configuration.

  Here, an example of the coupler array diagram and sub-routing diagram created in step S112 will be described. FIG. 14 is a diagram illustrating an example of a coupler array diagram. FIG. 15 is a diagram illustrating an example of a sub-wiring diagram. In the coupler arrangement diagram shown in FIG. 14, the circuit connection between the couplers 202 and 203 and the coupler 201 as a lumped joint is shown. The coupler 201 is a head coupler, and the couplers 202 and 203 are child couplers. In FIG. 14, the couplers 201 to 203 are identified by numbers “404”, “51”, and “50”, respectively. The circuit of the number “130” is connected to the coupler 201 and the coupler 202, and the circuit of the number “131” is connected to the coupler 202 and the coupler 203. Further, the circuit of the number “132” has a terminal stop at the other end. Information of each of the couplers 201 to 203 and the circuit is described on the coupler arrangement diagram. In addition, the circuit wiring sequence 204 is shown on the coupler arrangement diagram. In addition, the order of creating the sub-harness constituent units is also described as the sub-order. The coupler array shown in FIG. 14 is “0002”. In addition, as shown in FIG. 14, the components attached in a subharness preparation stage, for example, the round tubes 205 and 206, are also described. However, the corrugated tube and the split tube can be attached even if they are not in the sub-harness assembly stage. Similarly, a rear holder to be inserted at the time of double locking and a through clamp to be mounted on the coupler need to be attached at the time of assembling the sub-harness, and therefore are described in this coupler arrangement diagram.

  FIG. 15 is an example of a sub-wiring diagram corresponding to the sub-harness configuration of FIG. The attachment positions of the coupler and the circuit on the ASSY plate can be known, and the sub-harness can be easily assembled while recognizing other sub-harness configurations and the overall wire harness configuration. Note that the coupler arrangement diagram shown in FIG. 14 and the sub-attached diagram shown in FIG. 15 can be made easier to see by colorization.

  In the embodiment described above, the tree structure up to the grandchild coupler is a sub-harness configuration, but this is a case of a wire harness incorporated in the vehicle. It may be added, or a sub-harness configuration including a sub coupler may be used.
