Description

  The present invention relates to a work management apparatus, a work management system, and a work management method that can easily manage a work start status.

  Conventionally, when performing work management, a method of inputting work start and work end from a terminal of a work record collection system or a wireless handy terminal is generally used.

In addition, as a method for specifying a work time which is one index of work management, an ID tag for identifying a worker and an ID tag for identifying a work target for identifying a work target item are ID tags. Reading with a reading device (IC (Integrated Circuit) tag reading device), and transmitting the read information, information for specifying a work area, and operation information of work equipment in the work area to a results management CPU (Central Processing Unit) Thus, a technique for managing work time is disclosed (for example, see Patent Document 1).
Japanese Patent Laying-Open No. 2005-182656 (paragraphs 0023 to 0034, FIG. 1)

  In the method using the terminal of the work record collection system or the wireless handy terminal, it is necessary for the worker to interrupt the assembly work and input the work record, and there is a problem that the assembly efficiency is reduced and the burden on the worker is increased.

  The IC tag reader of the work record collection system described in Patent Document 1 is a reader that is installed in a work area and covers a wide area of the work area where work target articles are conveyed. Therefore, since the IC tag reader reads all the IC tags in the work area, the IC tag for managing the traceability of the components other than the worker identifying IC tag and the work target identifying IC tag necessary for work management. There is a problem that a lot of information is read and a malfunction occurs.

  In addition, even if the worker starts work in the work area, it is found that the mounting parts are not complete during the assembly process, and the work is interrupted. Suspend work when there is not enough. In such a situation, there is a problem that the measurement of the work start time is not accurate and the work time cannot be accurately grasped.

  In addition, work that has to be performed by qualified workers (qualified personnel), such as precision work, must be performed by an unqualified person and work drawings can be checked without checking the work drawings. There is a risk that the work may be performed using an unmanaged tool, or the work may be performed using a part whose quality is not confirmed without using a regular part.

  An object of the present invention is to provide a work management apparatus, a work management system, and a work management method capable of easily managing the start status of work, which is an invention for solving the above-described problems.

  In order to achieve the object, the work management device is attached to a place (for example, work management box 21) where an IC tag in which information for specifying work contents is written is placed, and the IC tag placed in the place is placed. IC tag reading means (for example, IC tag reader / writer 25) that detects and detects the information, and work start condition determination means (for example, control unit 26) that determines work start conditions based on the read information of the IC tag reading means. ) And notification means (for example, LED lamp 23) for notifying the start of the work according to a command from the work start condition determining means.

  According to such a configuration, when the IC tag is placed in the place, the work start condition determining means can manage whether the work start conditions in the work area are met, and the work start disapproval ( It is possible to notify the notification means whether the work start permission (matches the start condition) or not.

  According to the present invention, it is possible to easily manage the work start status.

Embodiments of the present invention will be described below with reference to the drawings.
<< First Embodiment >>
FIG. 1 is a configuration diagram illustrating a work management system and a work management apparatus. The work management system 100 includes an instruction issuing device 10, a work management device 20, and a server 30. The instruction issuing device 10, the work management device 20, and the server 30 are connected by a network 40 such as a LAN (Local Area Network).

  The instruction issuing device 10 is a terminal that issues an instruction when work is required, and registers instruction contents and assembly instruction information in the storage unit 31 of the server 30. The assembly instruction information is information on parts and procedures necessary for assembling (assembling) products and semi-finished products. Here, as an example of the assembly instruction information, an assembly process for attaching components to the electronic circuit board 74 (see FIG. 4) is taken as an example.

  The instruction issuing device 10 includes an information processing unit 11, a keyboard 13, a display device 14, an IC tag reader / writer 15, and a sheet rewriting printer 16. The information processing unit 11 includes an instruction issuing unit 12 that issues instructions, and outputs an instruction 50 by the sheet rewriting printer 16 in accordance with an instruction from the instruction issuing unit 12. Further, the IC tag reader / writer 15 writes information for specifying the work content in the IC tag 51 in accordance with an instruction from the instruction issuing unit 12.

  The information for specifying the work content is, for example, an instruction number, a product name or model number of a product / semi-finished product to be manufactured, and the number of producers. In addition, as detailed information of information specifying the work contents of the work target article, assembly information when the worker attaches the component 75 (see FIG. 4) to the electronic circuit board 74 (see FIG. 4) is described. . Specifically, the type of the component 75, the number of components, and the mounting order of the components. Furthermore, the information for specifying the work content includes a work start condition described later.

  The instruction 50 is a document in which information for specifying the work content including the work start condition is described. The work start conditions are: (i) that the parts necessary for performing the work of the order are prepared and arranged at the work place, or are arranged by the work start time, (ii) the work of the order (Iii) The number of workers required to perform the instructions including not only the number of people but also whether the work is appropriate or not is complete. Or that the relevant person can start work, (iv) that the jigs necessary to perform the work of instructions are available, or that the relevant jigs are available. A specific example of the instruction 50 will be described with reference to FIG.

  FIG. 2 is an explanatory diagram illustrating an example of an instruction. In the instruction number A0011, a process ID, instruction contents, and work start conditions are described. The work start conditions include a work drawing ID (for example, D1234), an operator ID (for example, M2342), a work tool ID (for example, Tool345, Tool346, Tool347, Material233), and a used kit ID (for example, T0011). ) Is specified. Here, the tools include used jigs, tools, and equipment numbers.

  In FIG. 2, the work drawing ID is specified as identification information for specifying the work drawing among the identification information for identifying the work drawing. When the work identification ID is not specified, the work start condition is only the identification information. Since the worker ID, the work tool ID, and the layout kit ID are the same, the description thereof is omitted.

  Returning to FIG. 1, the IC tag 51 uses a non-contact wireless IC tag such as RFID (Radio frequency identification) and is attached to a document as an instruction 50. Note that the IC tag 51 is preferably a battery-mounted type that obtains power from received radio waves, for example, because it is easy to achieve downsizing and cost reduction, but may be a battery-mounted type. .

  The work management apparatus 20 includes a work management box 21 having an LED (Light Emitting Diode) lamp 23 and a slot 24, and a work management apparatus body 22 attached to the back of the work management box 21. Details of the configuration will be described with reference to FIG.

  FIG. 3 is a block diagram illustrating a configuration of the work management apparatus. The work management apparatus 20 has a function of reading various IC tags, determining a work start condition of the instruction, displaying the determination status by the LED lamp 23, and a function of transmitting the read information to the server 30. Yes. The work management apparatus main body 22 includes an IC tag reader / writer 25, a control unit 26, a communication unit 27, an input unit 28, and a storage unit 29.

  The work management box 21 is a box into which the instruction 50 is input at the start of work. When the work is completed, the worker takes out the instruction 50 from the work management box 21, attaches the taken instruction 50 to the electronic circuit board 74 (see FIG. 4), and delivers it to the next step.

  When the IC tag reader / writer 25 confirms communication with the IC tag 51 when the instruction 50 is inserted into the work management box 21, the IC tag reader / writer 25 reads the information of the IC tag 51 attached to the instruction 50 and starts communication with the control unit 26. Send information and read information. Further, when the IC tag reader / writer 25 confirms that the communication with the IC tag 51 is disconnected when the instruction 50 is taken out from the work management box 21, the IC tag reader / writer 25 transmits communication end information to the control unit 26.

  Specifically, the control unit 26 is realized by a CPU that operates according to a program. When receiving the communication start information of the IC tag 51 attached to the instruction 50, the control unit 26 registers the read information in the storage unit 29. The read information is an instruction number, a process ID, an instruction content, and a work start condition. When the other IC tag information and the work start condition already registered in the storage unit 29 are satisfied, the control unit 26 notifies the server 30 via the communication unit 27 when the work start condition is satisfied. Communication start information and information for specifying work contents are transmitted. The communication start information includes, for example, the ID of the work management box 21 and the communication start time. The information specifying the work content includes, for example, the order number of the order 50, the product number of the manufactured product / semi-finished product, the number of production personnel, and the work start condition. In addition, when the communication end information of the IC tag 51 attached to the instruction 50 is received, the control unit 26 specifies the communication end information with the IC tag 51 and the work content to the server 30 via the communication unit 27. Send information and. The communication end information includes, for example, the ID of the work management box 21 and the communication end time. The information specifying the work content includes, for example, the order number of the order 50, the product number of the manufactured product / semi-finished product, the number of production personnel, and the work start condition.

  The work management box 21 is loaded with a plurality of IC tags. For example, a worker identification IC tag in which information for identifying a worker is written, a tool identification IC tag in which information for identifying a tool is written, and a drawing identification IC in which information for identifying a work drawing is written There are a tag, an IC tag for identifying a kit, in which information for identifying a component kit is written. When the IC tag is inserted, the IC tag reader / writer 25 reads the information of the IC tag, and transmits to the control unit 26 information for starting communication with the IC tag and specifying information.

  The operator may hold the IC tag for specifying the worker, the IC tag for specifying the tool, the IC tag for specifying the drawing, and the IC tag for specifying the layout kit over the front surface of the work management box 21. The IC tag reader / writer 25 can read the held IC tag.

  Further, the control unit 26 determines a work start condition based on the read information of the IC tag reader / writer 25, and instructs the LED lamp 23 to display color (light emission color) based on the determination result. A detailed control program flowchart will be described later (see FIG. 7). The input unit 28 performs input such as initial setting of the control unit 26.

  The LED lamp 23 has, for example, light emitting diodes of three primary colors RGB (red, green, blue) of light, and has a rectangular lens in front of the light emitting diodes. Thereby, the worker and the work manager can confirm the work start state of the work area. The emission color of the LED lamp 23 is preferably different depending on the work start status. For example, the color is white when waiting for work, yellow when inputting an instruction, green when the work start condition is satisfied and starting, blue when working, and red when the work start condition is not satisfied. Thereby, the work manager who manages a plurality of work areas can determine which work area has the problem of the work start condition by checking the emission color of the LED lamp 23. Note that the LED lamp 23 may display characters or the like as an LED display type when it is necessary to display detailed information on the progress of work.

  The server 30 (see FIG. 1) is a server that stores work performance information from a plurality of manufacturing areas and analyzes the work performance information. The server 30 stores the registration information from the instruction issuing device 10 in the storage unit 31. In addition, when the server 30 receives information from the work management device 20, that is, communication start information, information for specifying work contents, and communication end information, the server 30 stores the information in the storage unit 31. Time information (time stamp) including date is added to the received information and stored. The time information stored in the storage unit 31 includes a communication start time included in the communication start information, a communication end time included in the communication end information, and time information (time stamp) added to the received information. The time information (time stamp) added to the received information may be used as a backup of the communication start time and communication end time. When the time information is not included in the information sent from the work management apparatus 20, the time information (time stamp) added to the received information is used for managing the received information. For example, the server 30 calculates a work time for each instruction from the information in the storage unit 31 and stores the calculation result in the storage unit 31.

  FIG. 4 is an external perspective view showing an example of a work table in the work area. Next to the work table 71, a self-supporting work management device 20 is installed. The upper part (upper surface) of the work table 71 is an assembly work area of the electronic circuit board 74, and a plurality of parts boxes 72 and a layout kit (parts box) 63 are installed in front of the worker. A plurality of tools 62, a work drawing 61, and a worker ID certificate 64 are placed on the upper part (upper surface) of the work table 71. The work drawing 61, the tool 62, the layout kit 63, and the worker ID certificate 64 include a work drawing specifying IC tag 61a, a tool specifying IC tag 62a, a layout kit specifying IC tag 63a, and a worker specifying for identifying each of them. An IC tag 64a is provided. The display device 80 is installed on the upper part of the work auxiliary stand 73 and displays work content information. The worker performs work on the electronic circuit board 74 according to the information displayed on the display device 80.

  FIG. 5 is an explanatory diagram illustrating an example of a screen displayed on the display device during work. This will be described with reference to FIGS. The display device 80 displays information related to work, and the screen is switched when the switch 76 is pressed, and is connected to the server 30 via the network 40. When the server 30 receives the information specifying the work transmitted from the work management apparatus 20, the server 30 displays the corresponding work content on the display device 80. The display device 80 includes an instruction number 81, instruction contents 82 (including the model number, product name, and number (number) of products and semi-finished products to be assembled), assembly instruction information 83 (procedure and work contents), process ID 84, A worker ID 85, the number of completed workers (completed number) 86, a work start date / time / work end date / time 87, and a detailed work time 88 are displayed.

  In the instruction number 81, information (for example, A0011) specifying the work content corresponding to the IC tag 51 is displayed. Further, in the instruction content 82 and the assembly instruction information 83, detailed information (procedure, work content) regarding the instruction number 81 is displayed. In the process ID 84, information for specifying a process (for example, W0001) is displayed. In the worker ID 85, information for identifying the worker (for example, M2342) is displayed. The information for specifying the worker may be registered in the storage unit 31 of the server 30 in advance, or the worker may provide an IC tag (not shown) for specifying the worker. May be recognized by the server 30 and displayed on the worker ID 85.

  In the work start date / time and the work end date / time 87, the time when the instruction 50 is input to the work management box 21 and the work is started and the time taken out from the work management box 21 are displayed. The number of completed members 86 indicates the number of completed members out of the number of production members (eight here). The detailed work time 88 displays the end time of each procedure. For example, when the switch 76 is pressed at the end of each procedure, the time is displayed. In this way, the worker can reliably proceed with the work in accordance with the work content instruction on the display screen of the display device 80.

  FIG. 6 is an explanatory diagram showing work results for each work process stored in the storage unit of the server. For each order No., the work start time, work end time, information regarding work processes, information regarding workers, information regarding work drawings, information regarding work tools, and information regarding parts used (layout kit) are stored. . According to FIG. 6, for example, work content (instruction No.) A0011, which is one of the entire work processes W0001, starts work at time 9:00 by worker M2342 on May 10, 2006, and time 9 : It turns out that it is completed at 35. Further, it can be seen that the work content (instruction No) A0011 uses the work drawing D1234, the tools Tool 345, Tool 346, Tool 347, Material 233, and the layout kit T0011.

Next, the work start status display function of the work management apparatus 20 will be described.
FIG. 7 is a flowchart illustrating a display procedure for starting work of the work management apparatus according to the first embodiment. When the power of the work management apparatus 20 is turned on, the control unit 26 issues an initial notification command to the LED lamp 23 and turns on white (step S101). Note that the LED lamp 23 holds the emission color until a next notification command is received by a light emission color holding circuit (not shown). Here, the emission color holding circuit is on the LED lamp 23 side, but may be on the control unit 26 side. As shown in FIG. 4, when the worker in the work area receives the electronic circuit board 74 to which the instruction 50 is attached, the instruction 50 is input to the insertion port 24 of the work management box 21 installed beside the work table 71. From. The IC tag reader / writer 25 transmits a radio wave including a control signal from an antenna (not shown) in the IC tag reader / writer 25 every predetermined time, and determines whether or not the insertion of the instruction 50 is detected (step S102). ). In step S102, the radio wave including the control signal may be continuously transmitted from an antenna (not shown) in the IC tag reader / writer 25.

  When the antenna in the IC tag 51 receives a radio wave from the IC tag reader / writer 25, an electromotive force is generated by the resonance action of the antenna. A circuit in the IC tag 51 is activated by the generated power and performs necessary processing. The processing result is transmitted from the antenna on the IC tag 51 side. The IC tag reader / writer 25 receives the transmitted radio wave with the antenna in the IC tag reader / writer 25 and detects the insertion of the instruction 50 (Yes in step S102). If the IC tag reader / writer 25 cannot detect the insertion of the instruction 50 (No at Step S102), Step S102 is continued.

  The IC tag reader / writer 25 reads the detected information of the IC tag 51, and the control unit 26 sends the server 30 via the communication unit 27 and the network 40 the communication start information with the IC tag 51 as the instruction input information and the work. Information specifying the content is transmitted (step S103). Then, the control unit 26 issues an instruction insertion notification command to the LED lamp 23 to light yellow (step S104). Further, the control unit 26 initializes the work start condition flag management table shown in FIG.

  FIG. 8 is an explanatory diagram illustrating a management table of work start condition flags in the first embodiment. FIG. 8A shows the state of the management table at the initial time, FIG. 8B shows the state of the management table when the worker is preparing to start work, and FIG. 8C shows the worker. This is the state of the management table at the completion of preparations for starting work. The work start condition flag management table is stored in the storage unit 29, and there are a work drawing ID, a worker ID, a work tool ID, and a layout kit ID as ID types, and corresponding flag types (for example, D, M, T, P) and flag values (for example, 0, 1, 2). The flag value 0 is a case of initial setting, the flag value 1 is a case where the work start condition of the IC tag 51 of the instruction 50 matches the ID type and the ID value, and the flag value 2 is This is a case where the work start condition of the IC tag 51 of the instruction 50 matches only the type of ID. Details of FIGS. 8B and 8C will be described later.

  Returning to FIG. 7, the control unit 26 determines whether or not there is detection (ID detection) of another IC tag (step S <b> 105). When there is ID detection (step S105, Yes), it progresses to step S106, and when there is no ID detection (step S105, No), step S105 is continued.

  In step S106, the control unit 26 determines whether or not the detected ID is a work drawing ID. If the detected ID is a work drawing ID (step S106, Yes), the process proceeds to step S107. If the detected ID is not a work drawing ID (step S106, No), the process proceeds to step S110. In step S <b> 107, the control unit 26 determines whether or not the detected work drawing ID matches the work drawing ID of the work start condition of the instruction 50. When the detected work drawing ID matches the designated work drawing ID (step S107, Yes), the control unit 26 issues a corresponding ID notification command to the LED lamp 23 to light yellow, and the corresponding flag (D Flag) is set to 1 (step S108). If the detected work drawing ID does not match the designated work drawing ID (No at step S107), a non-corresponding ID notification command is issued to the LED lamp 23, the red light is turned on, and the corresponding flag (D flag) is set to 2. (Step S109). Then, the process proceeds to step S110.

  In step S110, the control unit 26 determines whether or not the detected ID is a worker ID. If the detected ID is a worker ID (step S110, Yes), the process proceeds to step S111. If the detected ID is not a worker ID (step S110, No), the process proceeds to step S114. In step S111, the control unit 26 determines whether or not the detected worker ID matches the worker ID of the work start condition in the instruction 50. When the detected worker ID matches the designated worker ID (step S111, Yes), the control unit 26 issues a corresponding ID notification command to the LED lamp 23 to light yellow, and the corresponding flag (M Flag) is set to 1 (step S112). If the detected worker ID does not match the designated worker ID (No at Step S111), a non-corresponding ID notification command is issued to the LED lamp 23, and the corresponding flag (M flag) is set to 2 (Step S113). Then, the process proceeds to step S114.

  In step S114, the control unit 26 determines whether or not the detected ID is a work tool ID. If the detected ID is a work tool ID (step S114, Yes), the process proceeds to step S115. If the detected ID is not a work tool ID (step S114, No), the process proceeds to step S118. In step S115, the control unit 26 determines whether or not the detected work tool ID matches the work tool ID of the work start condition in the instruction 50. When a plurality of work tools are designated, the control unit 26 determines all the designated numbers. When the detected work tool ID matches the specified work tool ID (step S115, Yes), the control unit 26 issues a corresponding ID notification command to the LED lamp 23 to light yellow, and the corresponding flag. (T flag) is set to 1 (step S116). If the detected work tool ID does not match the specified work tool ID (No in step S115), a non-corresponding ID notification command is issued to the LED lamp 23, and the corresponding flag (T flag) is turned on. Is set to 2 (step S117). Then, the process proceeds to step S118.

  In step S118, the control unit 26 determines whether or not the detected ID is a layout kit ID. When the detected ID is a layout kit ID (step S118, Yes), the process proceeds to step S119, and when the detected ID is not a layout kit ID (step S118, No), the process proceeds to step S122. In step S119, the control unit 26 determines whether or not the detected layout kit ID matches the layout kit ID of the work start condition of the instruction 50. If the detected distribution kit ID matches the specified distribution kit ID (step S119, Yes), the control unit 26 issues a corresponding ID notification command to the LED lamp 23 and lights yellow, and the corresponding flag (P Flag) is set to 1 (step S120). If the detected layout kit ID does not match the specified layout kit ID (No at step S119), a non-corresponding ID notification command is issued to the LED lamp 23, and the corresponding flag (T flag) is set to 2 (Step S121). Then, the process proceeds to step S122.

  The control unit 26 determines whether any of the flags has been changed (step S122). If there is no flag change (step S122, No), the control unit 26 issues a non-corresponding ID notification command to the LED lamp, and lights up red (step S123). If there is a flag change, the process proceeds to step S124.

  In step S124, the control unit 26 determines whether or not all flags are set to 1 for each ID. If all the flags are not set to 1 (No at Step S124), the process returns to Step S105. When all the flags are set to 1 (step S124, Yes), the process proceeds to step S125. An example of the detailed work start condition flag management table in step S125 is shown in FIGS. 8B and 8C.

  In FIG. 8B, the work drawing ID, the worker ID, the work tool ID, and the layout kit ID can be detected. However, since the worker ID is different from the worker ID specified by the instruction, the M flag is set. 2 is set. Similarly, one T flag of the work tool ID is set to 2. In such a case, the process returns to step S105. In FIG. 8C, all the flags are set to 1, and the process proceeds to step S125.

  Returning to FIG. 7, in step S <b> 125, the control unit 26 issues a work start notification command to the LED lamp 23 to light up green. And the control part 26 transmits work start information to the server 30 (step S126). After the transmission is completed, the control unit 26 issues an in-operation notification command to the LED lamp 23 to light blue (step S127), and proceeds to step S128.

  In step S128, the IC tag reader / writer 25 performs communication with the IC tag 51 every predetermined time, and when the communication is confirmed, the operator gives an instruction 50 and the input 24 of the work management box 21. (Step S128, No), and returns to Step S128. If communication cannot be confirmed within the predetermined time, it is detected that the operator has taken the instruction 50 from the insertion port 24 of the work management box 21 (step S128, Yes), and the process proceeds to step S129.

  The control unit 26 transmits, to the server 30 via the network 40, communication end information with the IC tag 51, which is IC tag extraction information, and information for specifying the work content (step S129). Thereafter, the control unit 26 returns to step S101, issues an initial notification command to the LED lamp 23, and lights up white. Further, the control unit 26 initializes the management table of the work start condition flag as shown in FIG.

  According to the present embodiment, the work management box 21 into which the IC tag 51 in which the information for specifying the work content including the work start condition is written is input, and the work management box 21 is attached to the work management box 21. An IC tag reader / writer 25 that detects the detected IC tag and reads the information, a control unit 26 that determines a work start condition based on the read information of the IC tag reader / writer 25, and an instruction of the control unit 26 that notifies the start of the work LED lamp 23 to be used. For this reason, the start status of the work after the IC tag 51 is inserted is notified by the LED lamp 23, so that the worker and the manager of the work can easily grasp the start state of the work. Further, since the work start condition is set and the work start time based on the accurate work start time and the work end time when the instruction 50 is taken out from the work management box 21 are stored in the server 30, the substantial work time can be reduced. Can be collected.

  Note that, according to the flowchart shown in FIG. 7, four items of work drawing ID, worker ID, work tool ID, and layout kit ID are used as the work start condition items specified in the instruction 50, and the work drawing ID is set. A determination is made (S106 to S109), the worker ID is determined (S110 to S113), the work tool ID is determined (S114 to S117), and the layout kit ID is determined (S118 to S121). However, each determination described above may actually be realized in parallel. Here, it is shown as a flow of a series of operations for convenience. Further, the order of the work start condition items does not matter. Furthermore, it is preferable that the number of work start condition items varies depending on the work start condition specified in the instruction 50. For example, when an administrator wants to specify only workers having specific skills when issuing an instruction 50, an operator ID may be specified as the work start condition of the instruction 50.

<< Second Embodiment >>
FIG. 9 is a flowchart illustrating a display procedure for starting work of the work management apparatus according to the second embodiment. In the first embodiment, as the work start condition, as shown in FIG. 2, when the ID type and the ID value of the work start condition specified in the instruction 50 match, the work start condition is indicated. It was. In the second embodiment, a case where only the type of ID is specified in the work start condition of the instruction 50 (when the value of ID is not specified) will be described. In this case, if the work start condition satisfies only the specified ID type, the control unit 26 issues a work start notification command. In FIG. 9, the same steps described in FIG. 7 are denoted by the same step numbers and description thereof is omitted. In FIG. 9, step S107, step S111, step 115, and step S119 are excluded compared to FIG. Therefore, step S106 to step S120 will be described next.

  In step S106, the control unit 26 determines whether or not the detected ID is a work drawing ID. If the detected ID is a work drawing ID (step S106, Yes), a corresponding ID notification command is issued to the LED lamp 23 to light yellow, and the corresponding flag (D flag) is set to 1 (step S108). . The ID detected at this time is registered in the work start condition flag management table, and the process proceeds to step S110. If the detected ID is not a work drawing ID (No in step S106), the process proceeds to step S110.

  In step S110, the control unit 26 determines whether or not the detected ID is a worker ID. When the detected ID is the worker ID (step S110, Yes), a corresponding ID notification command is issued to the LED lamp 23 to light yellow, and the corresponding flag (M flag) is set to 1 (step S112). . The ID detected at this time is registered in the work start condition flag management table, and the process proceeds to step S114. When the detected ID is not the worker ID (No at Step S110), the process proceeds to Step S114.

  In step S114, the control unit 26 determines whether or not the detected ID is a work tool ID. If the detected ID is a work tool ID (step S114, Yes), a corresponding ID notification command is issued to the LED lamp 23 to light yellow, and the corresponding flag (T flag) is set to 1 (step S116). ). The ID detected at this time is registered in the work start condition flag management table, and the process proceeds to step S118. If the detected ID is not a work tool ID (step S114, No), the process proceeds to step S118.

  In step S118, the control unit 26 determines whether or not the detected ID is a layout kit ID. If the detected ID is a layout kit ID (step S118, Yes), a corresponding ID notification command is issued to the LED lamp 23 to light yellow, and the corresponding flag (P flag) is set to 1 (step S120). . The ID detected at this time is registered in the work start condition flag management table, and the process proceeds to step S122. When the detected ID is not a layout kit ID (No at Step S118), the process proceeds to Step S122.

  FIG. 10 is an explanatory diagram illustrating a management table of work start condition flags in the second embodiment. FIG. 10A shows the state of the management table at the initial time, and FIG. 10B shows the state of the management table when the worker's work start preparation is completed. The work start condition flag management table is stored in the storage unit 29, and there are a work drawing ID, a worker ID, a work tool ID, and a layout kit ID as ID types, and corresponding flag types (for example, D, M, T, P) and flag values (for example, 0, 1). The flag value 0 is an initial setting value, and the flag value 1 is a case where the work start condition of the IC tag 51 of the instruction 50 matches the ID type.

  In the case of the second embodiment, since the work start condition is determined based only on the type of ID, the detected ID is registered in the work start condition flag management table. For example, according to FIG. 10B, the drawing of D1234 is used as the work drawing, and it can be seen that the person in charge of the ID of M2343 is in charge of the worker. The control unit 26 (see FIG. 3) transmits the work start information including the ID value shown in FIG. 10B to the server 30 when the work start information is transmitted (FIG. 9, step S126).

  According to the present embodiment, as the work start condition, the control unit 26 determines whether or not the work start condition is satisfied in the ID type (identification information), and the detected ID value (specific information) is To the server 30. For this reason, information such as work drawings, workers, work tools, and layout kits used in the work is registered in the server 30. These pieces of information can be used as traceability management information. The basic information in the traceability information is information on what kind of component the manufactured product is composed of, and further is individual identification information of the component that is actually used. That is, the basic traceability information is a so-called bill of materials (BOM), which is a name / model of a member and a manufacturing serial number or a manufacturing lot number for each manufactured product. Furthermore, information such as work drawings, workers, work tools, and layout kits managed here may be included.

  In the embodiment described above, the work start state is notified to the worker or the work manager by the LED lamp (notification means) 23. However, as the notification means, for example, the work start state may be notified by an alarm.
