Hereinafter, a case where an embodiment of an assembly instruction system according to the present invention is applied to a subline SL_b in an assembly line of an automatic transmission for a vehicle will be described as an example.
FIG. 1 is a schematic configuration diagram of a subline SL_b to which the assembly instruction system 10 according to the embodiment is applied.

  The subline SL_b to which the assembly instruction system 10 according to the embodiment is applied is a subline for assembling the subassembly Sb. In the assembly line for the automatic transmission for a vehicle, the subassembly Sb assembled by the subline SL_b is the main line. In the assembly process set on the line ML, the assembly is performed on the sub-assembly Sa assembled on another sub-line (not shown).

The subline SL_b is a line for assembling a pulley subassembly, for example. The first component Sb0 supplied to the subline SL_b passes through the work steps set in the subline SL_b in order, so that the subassembly Sb is finally obtained. Can be assembled.
The sub-line SL_b is a line that does not employ a work base on which the component parts are placed and a conveyance mechanism for conveying the work base. Is supposed to do. For this reason, the exclusive area in the factory is reduced as compared with the line employing the transport mechanism.

The subline SL_b is composed of a total of 10 processes from the work process 1 to the work process 10, and dedicated terminals 1 to 10 are provided in the work processes 1 to 10, respectively.
The work instructions in the work process in which the terminals are provided are input to the terminals 1 to 10 from the work information output device 40 (line PC) in a wired or wireless manner. Among the work steps 1, 2, 4 to 10 set so that the worker performs the work, a work instruction is output to the display device 28 (see FIG. 2) included in the terminals 1, 2, 4 to 10. It has become so.
In addition, a work device WM for performing work in the work process 3 is installed in the work process 3. When a work instruction is input to the terminal 3 in the work process 3, the work device WM is input from the terminal 3. The predetermined work is executed based on the command to be executed.

Hereinafter, the configuration of each of the terminals 1 to 10 and the configuration of the work information output device 40 will be described.
2 is a functional block diagram of the control unit 20 included in the terminals 1 and 10, FIG. 3 is a functional block diagram of the control unit 20 included in the terminals 2 to 9, and FIG. It is a functional block diagram of the control part 41 with which FIG.
In the following description of the configuration of the terminals 1 to 10, the configuration of the terminals 1 and 10 will be described as a representative, and the configuration different from the terminal 1 in the other terminals 2 to 9 will be described as appropriate.

  As shown in FIG. 2, the terminals 1 and 10 have a control unit 20 including a CPU and a memory (not shown). The control unit 20 includes a two-dimensional code (2D code) reading unit 21 and an attendance report. Unit 22, work instruction unit 23, work data generation unit 24, and completion report unit 25.

  Based on the output signal of the hand scanner 26, the two-dimensional code reading unit 21 generates information indicating the content of the two-dimensional code attached to the component (hereinafter referred to as two-dimensional code information). Then, the two-dimensional code reading unit 21 outputs the generated two-dimensional code information to the presence report unit 22.

  Here, in the embodiment, the hand scanner 26 is provided in the terminal 1 of the first process and the terminal 10 of the last process in the subline SL_b. Therefore, the two-dimensional code reading unit 21 of the terminal 1 generates the two-dimensional code information of the component Sb0 supplied to the work process 1, and the two-dimensional code reading unit 21 of the terminal 10 is supplied to the work process 10. Two-dimensional code information of the component Sb9 is generated.

Note that the two-dimensional code is a unique identification number assigned to a component part, and different numbers are assigned even for the same part. Therefore, one component can be specified from among a plurality of components by referring to the unique identification number.
Also, the two-dimensional code is imprinted on the component parts so as not to be separated from the component parts.

Based on the output signal of the presence sensor 27 installed in the work space of the work process 1, the presence report unit 22 determines whether the work target component is supplied to the work process 1 in which the terminal 1 is provided. To check.
When the supply of the component parts is confirmed, the presence report unit 22 outputs information indicating that the component parts are present in the work space (attended report) to the work information output device 40.
At this time, the presence report unit 22 includes, in the presence report, the two-dimensional code information input from the two-dimensional code reading unit 21, and an identifier (ID) for specifying the terminal that has output these presence reports. Is output to the work information output device 40.
Therefore, since the identifier indicating that the terminal that has output the presence report is the terminal 1 is added to the presence report output from the terminal 1, the presence report output from the terminal 1 is received. The work information output device 40 can identify that the received presence report is transmitted from the terminal 1 among a plurality of terminals by referring to the identifier added to the presence report. It has become.

The work instruction unit 23 instructs work in the work process provided with the terminal based on the work instruction input from the work information output device 40.
Here, when the work in the work process provided with the terminal 1 is a work performed by a worker, the work instruction unit 23 outputs information necessary for the work to the display device 28 of the terminal 1.
The information necessary for the work includes, for example, a list of parts to be assembled to the component parts in the work process, a procedure for assembling the parts, notes on performing the work, and the like, which are displayed on the display device 28. Will be.

In addition, when work in the work process is performed by the work device WM, for example, as in work process 3, the work instruction unit 23 generates a command for operating the work device WM based on the work instruction. Then, the generated command is output to the work device WM (see FIG. 3).
As a result, the work device WM performs a specific work based on the input command. Therefore, for example, when the working device WM is a device that tightens a bolt, a bolt tightening operation is performed.

The work data generation unit 24 generates information (hereinafter referred to as work data) indicating the content of the work actually performed in the work process 1 based on the output signal of the work sensor 29 installed in the work space of the work process 1. To the completion report unit 25.
The work data includes, for example, data that can be quantified, such as bolt fastening torque, and the work content information includes numerical data related to work that can be numerically managed.

  Specifically, the work data generation unit 24 is supplied to the work process 1 based on the output signal of the presence sensor 27 installed in the work space of the work process 1. It is confirmed whether or not the component that has been moved from the work process 1.

  When the detected component cannot be detected from the output signal of the presence sensor 27, the work data generation unit 24 determines that the work in the work process 1 for the component is completed, and the work data is stored. Generate.

  When the work data is input from the work data generation unit 24, the completion report unit 25 generates information (completion report) indicating that the work has been completed, and the generated completion report is input from the work data generation unit 24. The work data and an identifier (ID) for identifying the terminal that has output the completion report are added and output to the work information output device 40.

  Therefore, in the work information output device 40 that has received the completion report, by referring to the identifier added to the presence report, which terminal of the plurality of terminals has received the received completion report. Can be specified.

  The work information output device 40 includes a control unit 41 including a CPU and a memory (not shown). The control unit 41 includes a work instruction generation unit 42, a database update unit 43 (DB update unit), and a collation unit 44. A notification unit 45, a common identification number acquisition unit 46, a work information acquisition unit 47, a work database registration unit 48, and a storage unit 49 that stores a work database 50.

When the presence report from the terminal of the subline SL_b is input, the work instruction generation unit 42 refers to the identifier added to the presence report and identifies the terminal that transmitted the presence report.
When the identified terminal is the terminal 1, the two-dimensional code information added to the presence report is output to the common identification number acquisition unit 46. When the work database registration unit 48 notifies that the new registration has been completed, the work instruction generation unit 42 refers to the work database 50 and generates a work instruction for the terminal 1 that transmitted the presence report. The generated work instruction is transmitted to the terminal 1.

  On the other hand, when the identified terminal is not the terminal 1 (when the terminal is the terminal 2 to the terminal 10), the work instruction generation unit 42 refers to the work database 50 and generates a work instruction for the identified terminal. Then, the generated work instruction is transmitted to the identified terminal.

  When the identified terminal is not the terminal 1 and the two-dimensional code information is added to the presence report, the work instruction generation unit 42 outputs the two-dimensional code information to the collation unit 44 together with the identifier. . Then, after a match report is input from the collation unit 44 that is the output destination of the two-dimensional code information, the work instruction is generated.

The collation unit 44 acquires the two-dimensional code information of the components supplied to the work process of the identified terminal from the work database 50 after identifying the terminal that transmitted the presence report by the input identifier.
When the acquired two-dimensional code information matches the two-dimensional code information input from the work instruction generation unit 42, the collation unit 44 outputs a match report to the work instruction generation unit 42 and does not match. In the case, a mismatch report is output to the notification unit 45.

When the mismatch information is input from the collation unit 44, the notification unit 45 generates a command for operating the notification unit 51, and outputs the generated command to the notification unit 51.
Thereby, when the alerting | reporting means 51 is a speaker, the audio | voice message for alerting | reporting abnormality etc. is output from a speaker.

  When the two-dimensional code information is input from the work instruction generation unit 42, the common identification number acquisition unit 46 refers to the production management database 61 (production management DB) provided in the assembly control system and registers the two-dimensional code information. Two-dimensional code information is registered in association with a production control number (unit S / N) that has not been assigned.

Here, the production management database 61 will be described with reference to FIG.
As shown in FIG. 5, in the production management database 61, a unique production management number (unit S / N) indicating the production order on the production line is associated with an identification number (unit code) of the automatic transmission.
The unit S / N is a unique identification number whose number increases in the order of production on the production line. For example, a number “1” is added according to the order of production, such as Y0001, Y0002, Y0003,. It is a unique identification number.

  The unit code of the automatic transmission is an identification number for distinguishing the automatic transmission to be assembled, and a different number is set for each type of automatic transmission. For this reason, automatic transmissions of the same model each have the same unit code.

  In the production management database 61, a unit code for identifying the model of the automatic transmission to be produced is associated with each unit S / N, and it can be seen which type of automatic transmission is assembled for each unit S / N. It is like that.

  In the production management database 61 according to the embodiment, two-dimensional code information of components supplied to the first work process in each subline can be registered for each unit S / N. In the sub-line, the sub-assembly components are supplied in the order of production specified by the unit S / N. Therefore, the first component supplied to the sub-line is the first automatic transmission that is produced on the production line. It comes to be a part.

  Therefore, when the two-dimensional code information of the component is registered in association with the unit S / N, it is determined via the unit S / N which type of automatic transmission the component having the registered two-dimensional code information is assembled. It has come to understand.

  Therefore, the common identification number acquisition unit 46 registers the two-dimensional code information in association with the specific unit S / N of the production management database 61, and then acquires the unit code of the automatic transmission corresponding to the associated unit S / N. . Then, the common identification number acquisition unit 46 adds the registered two-dimensional code information to the acquired unit code and outputs it to the work information acquisition unit 47.

  When the unit code of the automatic transmission is input, the work information acquisition unit 47 refers to the product database 62 based on the unit code, and performs each work process of the subline SL_b for the component specified by the two-dimensional code information. Acquire information (work information) related to the work to be executed in. Then, the two-dimensional code information added to the unit code is added to the acquired work information and output to the work database registration unit 48.

Here, the product database 62 will be described with reference to FIG.
As shown in FIG. 6, in the product database 62, information on the main line constituting the assembly line of the automatic transmission and the work executed on each subline is associated with the unit code of the automatic transmission.
In the work information related to each subline, information related to work performed in each work process of the subline is registered separately for each work process.
For example, in the case of a model specified by the unit code MX01A, information regarding work performed in each work process from the work process 1 to the work process 10 of the subline SL_b is registered as work information A1 to A10).

  Therefore, when the unit code :: MX01A for identifying the model of the automatic transmission is input, the work information acquisition unit 47 refers to the product database 62 based on this unit code and performs each work process of the subline SL_b. The information (work information A1 to A10) related to the work to be executed is acquired.

  The work database registration unit 48 registers the input work information in the work database 50 in association with the two-dimensional code information added to the work information.

FIG. 7 is a diagram illustrating a configuration example of the work database 50.
In the work database 50, information indicating in which work process of the sub-line work process the component specified by the two-dimensional code information and each component for the component specified by the two-dimensional code information are displayed. Information indicating the contents of the work in the work process is stored in association with the two-dimensional code information.

  Therefore, when the information (work information) related to the work executed in each work process of the subline is input, the work information acquisition unit 47 obtains the two-dimensional code information added to the input work information and the work information. The information is registered in the work database 50 in association with each other.

  For example, when work information for the two-dimensional code: B0081 is input in FIG. 7, the component specified by the two-dimensional code is used for assembling the automatic transmission specified by the unit code MX01C. In the work process 1 to the work process 10, work information (C1 to C10) for the subline SL_b of the unit code MX01C shown in FIG. 6 is registered in order.

Hereinafter, processing in the terminal 1 to the terminal 10 and the work information output device 40 will be described.
FIG. 8 is a flowchart for explaining processing in the terminal 1 and the terminal 10, FIG. 9 is a diagram for explaining processing in the terminal 2 to the terminal 9, and FIGS. 10 and 11 are processing in the work information output device 40. It is a flowchart explaining these.

First, processing in the terminal 1 and the terminal 10 including the hand scanner 26 will be described.
In step S <b> 101, the presence report unit 22 confirms whether or not a component has been supplied to the work space in which the presence sensor 27 is provided.
When the supply of the component parts is confirmed (step S101, Yes), the presence report unit 22 confirms whether the reading of the two-dimensional code (2D code) is completed in step S102.
When the reading of the two-dimensional code is completed (step S102, Yes), the presence report unit 22 adds the two-dimensional code information and the terminal identifier to the presence report in step S103, and sends the presence information to the work information output device 40. Output toward.

In step S <b> 104, the work instruction unit 23 confirms whether or not a work instruction has been received from the work information output device 40.
When the work instruction is received (step S104, Yes), the work instruction unit 23 outputs the work instruction to the display device 28 in step S105.

In subsequent step S <b> 106, the completion report unit 25 confirms whether the work is completed based on the output signal of the presence sensor 27.
When the completion of the work is confirmed (step S106, Yes), in step S107, the work data generation unit 24 generates work data from the output from the work sensor 29 while the work is being performed, and the completion report unit 25. Output to.

  In step S108, the completion report unit 25 generates information (completion report) indicating that the work has been completed, adds work data and a terminal identifier to the generated completion report, and outputs a work information output device. Output to 40.

Here, since the terminal 2 to the terminal 9 do not include the hand scanner 26 provided in the terminal 1 and the terminal 10, the processing from the terminal 2 to the terminal 9 shown in the flowchart of FIG. There is no processing corresponding to step S102.
Further, since the work device WM works on the terminal 3 instead of the worker, in step S204 in the flowchart of FIG. 9, the work instruction unit 23 operates the work device WM based on the input work instruction. Command is generated, and the generated command is output to the work device WM.
Further, in step S206 in this case, the work data generation unit 24 generates work data based on the output from the work sensor 29 and the output from the work device WM while the work is being performed, and the completion report unit To 25.

Next, processing in the work information output device 40 will be described.
As shown in FIG. 4, presence reports transmitted from the terminals 1 to 10 are input to the work instruction generation unit 42 of the work information output device 40.
Therefore, in step S301, the work instruction generation unit 42 confirms whether an attendance report has been input.
When the presence report input is confirmed (Yes in step S301), in step S302, the work instruction generation unit 42 refers to the identifier added to the presence report, and the terminal that transmitted the presence report And whether it is the first terminal 1 in the subline SL_b.

  When the terminal that transmitted the presence report is the terminal 1 (Yes in Step S302), the work instruction generation unit 42 acquires the two-dimensional code information added to the presence report in Step S303, and acquires the acquired two-dimensional The code information is output to the common identification number acquisition unit 46.

In subsequent step S304, the common identification number acquisition unit 46 refers to the production management database 61 provided in the assembly control system 60 and associates the two-dimensional code information with the unit S / N in which the two-dimensional code information is not registered. And the identification number (unit code) of the automatic transmission associated with the registered unit S / N is acquired.
Then, the common identification number acquisition unit 46 outputs the acquired unit code of the automatic transmission to the work information acquisition unit 47 together with the two-dimensional code information.

  For example, when the two-dimensional code information is input when the production management database 61 is in the state shown in FIG. 5, the common identification number acquisition unit 46 does not have the two-dimensional code information associated with the unit S / N: Y4014. Therefore, the input two-dimensional code information is registered in association with the unit S / N: Y4014. Since this unit S / N is associated with the unit code: MX01C of the automatic transmission, the common identification number acquisition unit 46 outputs this unit code: MX01C to the work information acquisition unit 47.

In step S305, the work information acquisition unit 47 refers to the product database (DB) 62 based on the input unit code of the automatic transmission, and information on assembly in the subline SL_b of the automatic transmission specified by the unit code ( Work information).
Then, the work information acquisition unit 47 outputs the acquired work information to the work database (DB) registration unit 48 together with the two-dimensional code information.

  For example, when the association between the unit code and the work information in the product database 62 is in a state as shown in FIG. 6, the work information acquisition unit 47 uses the subline SL_b among the work information related to the unit code: MX01C. Work information (C1, C2,..., C10) relating to assembly is acquired and output to the work database registration unit 48.

In step S306, the work database registration unit 48 registers the input work information in the work database 50 of the storage unit 49 in association with the two-dimensional code information.
For example, as shown in FIG. 7A, in the work database 50, when the work information has been registered up to the unit S / N: Y4013, the work database registration unit 48 receives the input work information. Are registered in the area allocated to the unit S / N: Y4014.
Thereby, as shown in FIG. 7B, the work database 50 registers the work contents in each work process of the subline SL_b in association with the new two-dimensional code information: B0081. In addition, the registration of the work content and information indicating that the components are supplied to the first work process 1 at that time are also registered in the area corresponding to the work process 1 in the two-dimensional code information B0081. For example, in the case of FIG. 7B, the character information “present” indicating that the component is supplied is registered.

  Further, the work database registration unit 48 adds the newly registered two-dimensional code information to information indicating that the new registration in the work database 50 is completed, and outputs the information to the work instruction generation unit 42.

In subsequent step S307, the work instruction generating unit 42 refers to the work database 50 based on the two-dimensional code information added to the information indicating that the new registration is completed, and acquires work information in the work process 1. Based on the acquired work information, a work instruction in the work process 1 is generated.
In step S308, the work instruction generating unit 42 transmits the generated work instruction to the terminal 1.

  For example, in the case of the component specified by the two-dimensional code information: Y4014, the work instruction in the work process 1 is generated based on the work information (work C1) of the work process 1.

If the attendance report received by the work instruction generation unit 42 is not an attendance report transmitted from the terminal 1 (No in step S302), the work instruction generation unit 42 adds two-dimensional to the received presence report in step S309. Check if code information is added.
When the two-dimensional code information is not added (No at Step S309), the work instruction generating unit 42 executes the process at Step S307 and outputs a work instruction to the terminal that transmitted the presence report.

Specifically, the work instruction generation unit 42 identifies the work process in which the presence report was made based on the identifier added to the presence report. Then, the work instruction generation unit 42 refers to the work database 50 and waits for the information item indicating the work status for the component from among the work information regarding the specified work process to be supplied to the work process 2. The character information “waiting” indicating that it is in a state is searched.
Then, the work instruction generating unit 42 creates a work instruction from the retrieved work information.

  For example, when the work process for which the presence report has been made is work process 2, the work instruction generating unit 42 performs work on the component from the work information on work process 2 in the action database 50 (see FIG. 7). The work information (work C2) of the component (two-dimensional code information: B0080) whose information item indicating the state of “Waiting” is “waiting” is acquired, and a work instruction is generated from this work information (work C2).

  It should be noted that when creating a work instruction, an information item indicating a work state for a component among the information on the work process 2 associated with the two-dimensional code information: B0080 in the work database 50 is supplied to the work process 2. Is changed from character information “wait” indicating that the component is supplied to the work process 2 to character information “present”.

In addition, when two-dimensional code information is added to the received presence report (step S309, No), the work instruction generation unit 42 transmits the presence report with the added two-dimensional code information. Along with the terminal identifier, it is output to the collation unit 44.
In step S310, the collation unit 44 to which the two-dimensional code information is input refers to the work database 50 based on the two-dimensional code information, and the component to be supplied next to the work process of the terminal specified by the identifier. Get two-dimensional code information.
In step S311, the collation unit 44 checks whether the acquired two-dimensional code information matches the two-dimensional code information input from the work instruction generation unit 42. If the two-dimensional code information does not match (step S311). , No) A mismatch report is output to the notification unit 45.
As a result, error processing is executed in the notification unit 45 (step S312).

  On the other hand, if they match (step S311, Yes), the identifier of the terminal that sent the presence report is added to the match report, and is output to the work instruction generation unit. Thereby, the work instruction generating unit 42 executes the process of step S307 and outputs a work instruction to the terminal that has transmitted the presence report.

For example, when there is an attendance report from the terminal 10 of the work process 10, the matching unit 44 refers to the work database 50 based on the identifier of the terminal 10. Here, in the work database 50 of FIG. 7, the configuration item of the two-dimensional code information: A0013 in which the component to be supplied next to the work process 10 is “wait” in the information item indicating the status of the work on the component. Since it is a component, the collation unit 44 acquires the two-dimensional code information A0013.
Then, the collation unit 44 collates whether or not the acquired two-dimensional code information A0013 is the same as the two-dimensional code information added to the presence report input to the work instruction generation unit 42.
Therefore, when the added two-dimensional code information is “A0013”, the collation unit 44 outputs a match report to the work support generation unit 42.

  Next, the process performed by the database update unit 43 in the work information output apparatus 40 in parallel with the process of FIG. 10 will be described with reference to FIG.

  First, in step S401, the database (DB) update unit 43 checks whether a completion report has been received. When the completion report is received (step S401, Yes), in step S402, the database update unit 43 specifies the terminal that has transmitted the completion report based on the identifier attached to the completion report, and updates the work database (DB) 50. To reflect that the work on the specified terminal is completed.

For example, when the terminal that has transmitted the completion report is the terminal 3 of the work process 3, in the work database 50 shown in FIG. 7, the component specified by the two-dimensional code information: B0109 is supplied to the work process 3. It is in a state.
Therefore, the database update unit 43 changes the contents of the information item indicating the status of the work in the work process 3 of this component from “present” indicating that the component is supplied to the work process 3 (FIG. 7). (Refer to (a)), and change to “complete” indicating that the work in the work process 3 is completed (see (b) of FIG. 7). Simultaneously with this change, the content of the information item indicating the work state in the work process 4 is changed to “wait” indicating that the component is waiting to be supplied to the work process 4.

In step S403, the database update unit 43 acquires the unit S / N and the two-dimensional code information related to the component whose contents of the information item are changed from the work database 50.
