  The work management box 21 is a box into which the instruction 50 is input at the start of work. Further, 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, and delivers it to the next step. The work management box 21 is also used when a work manager or a skilled worker (hereinafter referred to as a registered worker) registers position information of parts necessary for assembling a work target article.

  When the IC tag reader / writer 22 confirms communication with the work identification IC tag 51 when the instruction 50 is inserted into the work management box 21, the IC tag reader / writer 22 reads the information of the work identification IC tag 51 attached to the instruction 50, Communication start information with the work specifying IC tag 51 and information for specifying the work content are transmitted to the database server 30 via the control unit 27. The communication start information includes the ID of the work management box 21 and the communication start time. The information for specifying the work content includes, for example, the instruction number of the instruction 50, the product number of the manufactured product / semi-finished product, and the number of production personnel. When the IC tag reader / writer 22 confirms the disconnection of communication with the work specifying IC tag 51 when the instruction 50 is taken out from the work management box 21, the IC tag reader / writer 22 sends the work specifying to the database server 30 via the control unit 27. The communication end information with the IC tag 51 for use and the information specifying the work content are transmitted. The communication end information includes the ID of the work management box 21 and the communication end time. The information for specifying the work content includes, for example, the instruction number of the instruction 50, the product number of the manufactured product / semi-finished product, and the number of production personnel.

  When the IC tag reader / writer 22 periodically performs the ID reading operation, the IC tag reader / writer 22 sets the communication start time as the first time when the start of communication with the work specifying IC tag 51 is detected. The time when communication disconnection is first detected may be the communication end time. A plurality of IC tags may be inserted into the work management box 21. As another IC tag, for example, there is an operator identifying IC tag 52 in which information for identifying the worker is written. When the worker specifying IC tag 52 is inserted, the IC tag reader / writer 22 reads the information of the worker specifying IC tag 52 and sends it to the database server 30 via the control unit 27 and the worker specifying IC tag 52. Communication start information and information for identifying the worker are transmitted. The communication start information includes, for example, the ID of the work management box 21 and the communication start time. When the IC tag reader / writer 22 confirms the disconnection of communication with the worker specifying IC tag 52 when the worker specifying IC tag 52 is taken out of the work management box 21, the IC tag reader / writer 22 notifies the database server 30 of the worker. Information on the end of communication with the identification IC tag 52 and information for identifying the worker are transmitted. The communication end information includes, for example, the ID of the work management box 21 and the communication end time.

  The component box unit 23 includes a component box base 231 on which an illumination switch 233 and a loop antenna 234 are installed, and a component box 232 in which components are stored. The illuminated switch 233 is a notification lamp that informs the storage location of a component during assembly work, and is a registration switch that is used when registering the component position. The IC tag reading function using the loop antenna 234 will be described with reference to FIG. In the present embodiment, the plurality of component box units 23 are arranged in a horizontal example, but the present invention is not limited to this. It may be arranged in two upper and lower stages according to the cell work table. In FIG. 1, the component box 232 is transparent for displaying the loop antenna 234, but does not need to be transparent.

  FIG. 2 is a block diagram showing an IC tag reading function of the component box unit. A plurality of loop antennas 234 installed in the component box unit 23 are connected to the unit controller 24. The unit controller 24 includes an antenna switch 241 and an IC tag reader / writer 242. The antenna switch 241 switches the loop antenna 234 every predetermined time, so that the IC tag reader / writer 242 can read the component identification IC tag 61 in the component box 232.

  For this reason, even when the contents of the parts installed in the parts box unit 23 are appropriately changed, the identification information (part position information) of the parts box unit 23 and the identification number for specifying the currently installed parts (For example, a part number) can be made to correspond. Specifically, in the embodiment of FIG. 1, when the component position information of the component box unit 23 is L01, L02,..., L10 from the left, the component part number of the component in each component position information is associated. Can do.

  The component position information of the component box unit 23 may be stored as unique identification information of the component box base 231 including the loop antenna 234 and the illumination switch 233 in the storage unit in the IC tag reader / writer 242. In FIG. 2, only the loop antenna 234 is installed in each component box unit 23 and the unit control unit 24 is configured. However, the present invention is not limited to this. An IC tag reader / writer including a loop antenna 234 may be provided for each component box unit 23.

  Returning to FIG. 1, the database server 30 is a server that stores the contents of the instruction 50 on the production line and the work performance information based on the instruction 50 and analyzes the work performance information. From the instruction issuing terminal 10 and the cell work terminal 20, The information is memorized.

  Specifically, the database server 30 stores registration information from the instruction issuing terminal 10 in the storage unit 31. Further, when registering the position information of the parts, the database server 30 receives the information from the cell work terminal 20, that is, the information specifying the work contents, the part number, and the part position information, and the instruction management table 32 of the storage unit 31. (See FIG. 6).

  When the database server 30 receives information from the cell work terminal 20, that is, communication start information, information for specifying work contents, and communication end information, the database server 30 stores the information in the storage unit 31. The received information is stored with time information (time stamp) including date. 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. If the time information is not included in the information sent from the IC tag reader / writer 22, the time information (time stamp) added to the received information is used for managing the received information. An arithmetic processing unit (not shown) of the database server 30 calculates, for example, a work time for each instruction from the information in the storage unit 31 and stores the calculation result in the storage unit 31.

  It should be noted that the manager terminal (not shown) of the database server 30 monitors the storage unit 31 of the database server 30 by searching the storage unit 31 of the database server 30 for the work plan in the work such as the issuing state of the instructions and the work results in the manufacturing process. Can be analyzed.

  FIG. 3 is an external perspective view showing an example of a cell work table in the work area. A work management box 21 of the cell work terminal 20 is installed below the cell work table 71, and an IC tag reader / writer 22 is attached to the work management box 21. The work management box 21 is inclined forward of the drawing so that the operator can easily input the instruction 50 at the start of the work and take out the instruction 50 at the end of the work. Thereby, the worker can easily visually check the presence / absence of the instruction 50 in the work management box 21. In addition, it is preferable that the insertion port of the work management box 21 is substantially vertical and upward. Thereby, the installation area of the work management box 21 can be minimized.

  The upper part (upper surface) of the cell work table 71 is an assembly work area of the electronic circuit board 74, and a plurality of component box units 23 are installed in front of the worker. The display device 25 is installed on the upper part of the work auxiliary table 72 and displays information on the work specifying IC tag 51. At the time of registering the part position information, the registration worker performs the part position information registration work in accordance with the information displayed on the display device 25. Further, at the time of the assembly work, the worker performs the assembly work of the electronic circuit board 74 according to the information displayed on the display device 25.

  Component position information (for example, L01, L02) may be described in the switch panel portion of the illumination type switch 233 of the component box unit 23. Thereby, it is easy for the registered worker to visually check whether or not the component position information displayed on the display device 25 matches the actual component position information.

  Next, the procedure for registering the component position information will be described with reference to FIGS. The feature of this embodiment is that there is a problem with the work flow line of the operator in order to determine the placement of the parts in the cell work table 71, so that the part placement can be determined on site. For this reason, in this embodiment, a registered worker skilled in work can easily register position information of parts necessary for assembling work target articles in accordance with the cell work table 71.

  FIG. 4 is an explanatory diagram showing an example of a registration screen for component position information of the cell work terminal. The menu button 253 of the input unit 252 of the display device 25 is pressed, and the part position information registration menu is pressed and selected using the cursor button 254. Then, when the registered worker inputs the instruction 50 into the work management box 21 in the work area, the registered content of the instruction 50 is displayed on the display unit 251.

  Items displayed on the display unit 251 include an instruction number 2511, instruction contents 2512 (including the model number, product name, and number of products and semi-finished products to be manufactured), assembly instruction information 2513, process ID 2514, registration start date / time and registration. It includes an end date and time 2515, a registrant ID 2516, and a completed number 2517. The assembly instruction information 2513 includes a display field for an operator's assembly procedure, work contents, and a part box unit number 2518. For example, the procedure number B001 is “Parts001 attachment”, and the procedure number B002 is “Parts002 attachment”. In the field of the component box unit number 2818, “L05” and “L03” (see FIG. 3) which are component position information at the time of registration are displayed. The contents displayed in the assembly instruction information 2513 may display the part number together with the work contents.

  FIG. 5 is a flowchart showing the process of registering the part position information. The registration worker depresses the menu button 253 of the input unit 252 of the display device 25 and uses the cursor button 254 to depress and select the part position information registration menu. Then, the registered worker inputs an instruction 50 into the work management box 21 in the work area. The IC tag reader / writer 22 transmits a radio wave including a control signal from an antenna (not shown) in the IC tag reader / writer 22 every predetermined time, and determines whether or not the insertion of the instruction 50 is detected (step S1). ). In step S1, radio waves including a control signal may be continuously transmitted from an antenna (not shown) in the IC tag reader / writer 22. If the insertion of the instruction 50 is not detected (step S1, No), the process returns to step S1.

  When the IC tag reader / writer 22 detects the insertion of the instruction 50 (step S1, Yes), the IC tag reader / writer 22 reads the detected information of the work specifying IC tag 51, and the database server 30 reads the work as IC tag insertion information. Communication start information with the identifying IC tag 51 and information for identifying the work content are transmitted (step S2). Then, the cell work terminal 20 displays a part position information registration screen on the display device 25 (step S3).

  The registration worker uses the cursor button 254 to select a target procedure column. For example, “B001”. Then, the control unit 27 of the cell work terminal 20 determines whether or not selection of a procedure column has been detected (step S4). When selection of the procedure column is detected (step S4, Yes), the process proceeds to step S5.

  The registered worker determines the work contents and places the corresponding component box 232 on the component box base 131 or rearranges the component boxes 232. When the position of the component box 232 is determined, the illumination type switch 233 corresponding to the component box is pressed. The control unit 27 of the cell work terminal 20 determines whether or not pressing (operation) of the illumination type switch 233 is detected (step S5). When pressing of the illumination type switch 233 is detected (step S5, Yes), the control unit 27 displays the detected component position information in the column of the component box unit number 1518 of the display unit 151, and proceeds to step S6. In step S5, pressing of the illumination type switch 233 is a form of operation, and detection of the press means that the operation is detected.

  The registered worker depresses the work switch 26 if the displayed component position information is acceptable. The control unit 27 of the cell work terminal 20 determines whether or not pressing (operation) of the work switch 26 is detected (step S6). When pressing of the work switch 26 is detected (step S6, Yes), the control unit 27 determines that the part position information has been determined, and transmits the instruction number, the process ID, the procedure number, the part part number, and the part position information in association with each other. (Step S7), move to the next procedure column, and proceed to Step S8. The database server 30 that has received the component position information from the cell work terminal 20 registers it in the instruction management table (see FIG. 6) in the storage unit 31.

  If the procedure column is not selected in step S4 (step S4, Yes), the process proceeds to step S8. In step S5, when pressing of the illumination type switch 233 is not detected (step S5, No), the process proceeds to step S8. In step S6, when the pressing of the work switch 26 is not detected (step S6, No), the process proceeds to step S8. In step S4, step 5 and step 6, also when the detection signal cannot be received for a predetermined time, the process proceeds to step S8.

  In step S8, the IC tag reader / writer 22 of the cell work terminal 20 performs communication with the work specifying IC tag 51 every predetermined time, and when the communication is confirmed, the operator gives the instruction 50, It is not detected that the work management box 21 has been taken out from the insertion port (No in step S8), and the process returns to step S4. When communication cannot be confirmed within a predetermined time, it is detected that the registered worker has taken out the instruction 50 from the insertion port of the work management box 21 (Yes in step S8). The IC tag reader / writer 22 transmits to the database server 30 communication end information with the work specifying IC tag 51, which is IC tag extraction information, and information for specifying the work content (step S9).

  In step S5, when the illumination switch 233 is pressed, the lamp of the illumination switch 233 is preferably turned on. The registration worker can easily determine whether it has already been selected.

  FIG. 6 is an explanatory diagram showing an instruction management table registered in the storage unit of the database server. In the instruction management table 32, an instruction number, a process ID, a procedure number, work contents, a part item number, part position information, and a registrant ID are registered. At the time of registering the instruction 50 from the instruction issuing terminal 10, the part position information column is initially blank. However, the part position information is registered in correspondence with the work content or the part number by the part position information registration process shown in FIG. Specifically, the part position information of the part number P001 is L05, and the part position information of the part number P002 is L03.

  FIG. 7 is an explanatory diagram showing an arrangement example of a component box. In the arrangement example shown in FIG. 7, the component part number is specified from the component identification IC tag 61 put in the component box 232, and the relationship between the component item number and the component position information is known. FIG. 7A shows an arrangement example of the comparative example. For example, when the part numbers P001, P002, P003, P004, and P005 are mechanically arranged in the part position information L01, L02, L03, L04, and L05. It is. In such a case, when actual assembly work is performed, it takes time to take out the parts, which may take time.

  On the other hand, FIG. 7B shows an example in which a registered worker who is a skilled worker rearranges and arranges the component boxes 232. For example, part numbers P001, P002, P003, P004, and P005 are arranged in the part position information L05, L03, L10, L09, and L02. The registration worker considers the position where the parts of the electronic circuit board 74 are assembled, and shortens the time required for taking out. Also, parts that are indistinguishable in appearance are not placed in the adjacent parts box, thereby ensuring the accuracy of work to prevent careless mistakes.

  FIG. 7C shows a case where the person in charge of supplying the component supplies a mistake in the arrangement example of the component box 232 in the work area. In the arrangement example of FIG. 7C, compared with the arrangement example of FIG. 7B, the part position information of the part number P001 should be L05, but is arranged in the part position information L06 at the time of supplying the part. In this case, combination information of the part number and part position information from the unit control unit 24 of the cell work terminal 20, and combination information of the part number and part position information registered in the instruction management table 32 shown in FIG. Therefore, a human error at the time of supplying parts can be prevented. In such a case, the database server 30 may issue a notification signal to the management terminal.

  FIG. 8 is an explanatory diagram showing an example of a work screen during the assembly work of the cell work terminal. In FIG. 8, the same components as those in FIG. The assembly instruction information 2513 includes a procedure, work content, and detailed work time 2519. The display unit 251 displays work start date / time / work end date / time 2515A. In the work start date / time and work end date / time 2515A, the time when the instruction 50 is input into the work management box 21 and the time when the instruction 50 is taken out from the work management box 21 are displayed. The number of completed members 2517 displays how many of the production members have been completed, and when the procedure of the assembly instruction information 2513 is completed, the control unit 27 displays the number of completed members.

  The detailed work time 2519 displays the end time of each procedure, and the control unit 27 displays the time when the work switch 26 (see FIG. 2) is pressed. Thus, the worker can proceed with the work while confirming according to the work content instruction on the display screen of the display device 25. Specifically, in the case of the procedure number B001, the control unit 27 of the cell work terminal 20 turns on the lamp of the illuminated switch 233 of the part position information corresponding to the part number corresponding to the procedure number B001. The component box 232 of the component to be taken out can be easily identified. In the example of FIG. 8, the procedure numbers B001 to B006 are displayed as a list, but may be sequentially displayed over a plurality of pages for each procedure number.
