  In the cell production method, it is known that the work efficiency changes greatly depending on the order of work procedures. For this reason, it is necessary for an administrator or the like to perform work analysis and frequently change work procedures.

  Conventionally, when the work procedure of the work process is changed by reviewing the work content at the work site and the manufacturing BOM (Bills Of Materials) (hereinafter referred to as the manufacturing parts table or M-BOM) is modified, Since correction was made every predetermined time by processing or the like, there was a problem that the correction timing of the manufacturing BOM did not always match and the work procedure could not be changed quickly. Specifically, in the case of a printed circuit board for control, there are about 10,000 points including assembly drawings for parts, so the manufacturing parts list is corrected by batch processing every predetermined time. On the other hand, the work procedure information displayed on the display unit of the cell work table can be corrected relatively quickly. For this reason, there is a difference between the correction time of the work procedure information and the correction time of the manufacturing parts table, and there is a problem in improving the production efficiency.

  The present invention is an invention for solving the above-described problems, and is work support that can improve work efficiency by linking instruction screen information that is work procedure information for assembling work target articles and manufacturing parts table information. It is an object to provide a system and a work support method.

  In order to achieve the object, the work support system of the present invention includes a management server (for example, the database server 30) that manages the work procedure of the worker, and a display unit (for example, according to the work procedure from the management server that is installed in the work place). And a work terminal (for example, cell work terminal 20) that displays work instructions on the display device 25), and updates the manufacturing parts list necessary for the work procedure in conjunction with the change of the order of the work procedure. Do.

  Instruction information (for example, instruction information 32) in which the sheet ID for identifying the work procedure to be displayed on the display unit of the work terminal and the screen information are associated with the storage unit of the management server, and the work procedure of the sheet ID and the sheet ID. And manufacturing part table information (for example, manufacturing part table information 33) in which the sheet unit part table is configured in the order of the work procedure.

  When the processing unit of the management server receives the order change instruction for the work procedure, the processing part changes the order for each unit associated with the sheet ID of the instruction information, and changes the order for each sheet unit part table of the manufacturing parts table information. It is characterized by exchanging.

  According to the present invention, work efficiency can be improved by linking instruction screen information, which is work procedure information for assembling work target articles, and manufacturing parts table information.

The communication end information includes the ID of the work management box 21 and the communication end time. The information specifying the work content includes, for example, the instruction ID 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 a lamp 233 and a loop antenna 234 are installed, and a component box 232 (component box) in which components are stored. The lamp 233 is a notification lamp that informs the storage location of parts during assembly work. 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. You may arrange | position in two steps of upper and lower sides according to the cell work table 71 (refer FIG. 4). In FIG. 2, the component box 232 is transparent for displaying the loop antenna 234, but does not need to be transparent.

  FIG. 3 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 (second IC tag reader). The antenna switch 241 switches the loop antenna 234 every predetermined time, so that the IC tag reader / writer 242 can read the sheet specifying IC tag 61 in the component box 232.

  For this reason, even when the contents of the components arranged in the component box unit 23 are appropriately changed, the identification information (component box position information) of the component box unit 23 and the identification for specifying the sheet currently arranged Information (for example, sheet ID) can be associated. Specifically, in the embodiment of FIG. 2, if the BOX position information of the component box unit 23 is LB01, LB02,..., LB10 from the left, each BOX position information and the sheet ID can be associated with each other. it can.

  The BOX position information of the component box unit 23 may be stored in the storage unit in the IC tag reader / writer 242 as unique identification information of the component box base 231 including the loop antenna 234 and the lamp 233. In FIG. 3, only the loop antenna 234 is installed in each component box unit 23 and the unit control unit 24 is provided. 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. 2, the database server 30 stores the instruction information 32 (see FIG. 7) and the manufacturing parts table information 33 (see FIG. 8) of the instruction 50 in the storage unit 31, and the instruction information 32, the manufacturing parts table information 33, It is a server that manages the correspondence of. The database server 30 is a server that stores work performance information based on the instruction 50 and analyzes the work performance information, and stores information from the instruction management terminal 10 and the cell work terminal 20.

  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.

  FIG. 4 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. During the assembling work, the worker performs the assembling work of the electronic circuit board 74 according to the information displayed on the display device 25.

  The BOX position information (for example, LB01, LB02) may be described in the panel portion of the lamp 233 of the component box unit 23. Thereby, it is easy for the operator to visually check whether or not the information of the component box unit number displayed on the display device 25 matches the position information of the actual box (BOX).

  The distributor who supplies the parts based on the picking list arranges the parts in the right direction from the part box 232 on the left side of the drawing of FIG. 4 in the order of the sheet ID. At this time, the sheet identification IC tag 61 in which the sheet ID is stored is put in the component box 232 together with the components to be supplied. Thereby, the BOX position information and the sheet ID are associated with each other.

  The worker takes out the component 73 from the component box 232 according to the operation procedure displayed on the display device 25 and performs the assembly operation on the electronic circuit board 74. Since components are arranged for each sheet ID in the plurality of component boxes 232, the corresponding component box 232 becomes empty after the work of a predetermined sheet ID is completed. Thereby, the operator can determine whether or not the parts to be assembled are securely assembled. In the state shown in FIG. 4, the two component boxes 232 from the left of the drawing have already been assembled and the components are empty.

  FIG. 5 is an explanatory diagram illustrating a display screen example of the display device. Reference is made to FIG. 4 as appropriate. The display screen shown in FIG. 5 is a screen that is displayed when the operator inputs the instruction 50 into the work management box 21. The display unit 251 shows work guidance for the contents of the assembly instruction on the cell work table 71, and is when the sheet ID is B0001. When the switch 26 of the cell work table 71 is pressed, the next sheet ID screen is displayed.

  Items displayed on the display unit 251 include an instruction ID 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, work start date / time, and work end. Date and time 2515, worker ID 2516, and number of completed workers 2517 are included. The assembly instruction information 2513 includes display fields for an operator's assembly procedure (sheet ID), work content, and component box unit number 2518. For example, the procedure (sheet ID) B0001 is “work guidance”, the procedure B0002 is “Parts 001 attachment”, and the procedure B0003 is “Parts 002 attachment”. In the column of the component box unit number 2518, “LB01” and “LB02” (see FIG. 4) which are BOX position information are displayed. The contents displayed in the assembly instruction information 2513 may display the part number together with the work contents.

  The input unit 252 of the display device 25 has a menu button 253. When the sheet movement is selected, the cursor button 254 can be used to move to a work procedure screen to start work from now on if necessary. it can.

  FIG. 6 is an explanatory diagram illustrating another display screen example of the display device. The display screen shown in FIG. 6 shows a specific example when a connector is inserted. The display unit 251 (see FIG. 5) includes an attachment part field 2521, an overall view field 2522, a detail field 2523, a part information field 2524, an operation elapsed time field 2525, a procedure number field 2526, and an interruption button 2527.

  The operator can confirm the attachment position of the connector in the attachment part column 2521 from the general view column 2522 and the detail column 2523. Further, it can be confirmed how much time has elapsed with respect to the target time in the work elapsed time column 2525. When the operation is interrupted, the elapsed time can be interrupted by pressing the interrupt button 2527, but is recorded in the database server 30 as the interruption time during the operation time.

  FIG. 7 is an explanatory diagram illustrating an example of instruction information. The instruction information 32 includes a product name (item name), an instruction ID, a process ID, a sheet ID, work contents, work place position information indicating the position of the cell work, and BOX position information indicating the position of the box (BOX) on the cell work table. (Part box position information), a part number, a screen ID for displaying on the display screen, a worker ID, and the like are registered. Specifically, when the sheet ID is B0001, it is work guidance, and when the sheet ID is B0002, it is an attachment work of Parts 001. A plurality of parts (for example, parts P101 and P102) are used for the attachment work of Parts 001. Further, although not shown, the necessary number of parts and the like are associated with linked information. The worker ID is registered when the worker inserts the worker specifying IC tag 52 (see FIG. 2) into the work management box 21.

  In FIG. 7, the workplace position information and the BOX position information are distinguished, but the present invention is not limited to this. For example, the work location position information and the BOX position information may be combined into a single BOX position information. In this case, the BOX position information is managed as unique identification information, for example, LS001LB01, and the control unit 27 of the cell work terminal 20 stores the sheet ID stored in the sheet specifying ID 61 in the component box 232 and the work place. The BOX position information including the position information is transmitted to the database server 30 in association with it, and the database server 30 determines whether or not the received sheet ID and BOX position information are included in the instruction information 32 (FIG. 9, (See step S8).

  FIG. 8 is an explanatory diagram showing an example of the manufactured parts table information. The manufacturing parts table information 33 includes a product name (article name), an instruction ID, a process ID, a sheet ID, work contents, work site position information, BOX position information, a part part number, part position information indicating a part position in a warehouse, and a staff member. An ID, a picking ID when the staff member picks, and the like are registered.

  The production parts table information 33 is created based on the instruction information 32, the management information in the warehouse, and the like. When the order of the sheet IDs in the instruction information 32 is changed, the BOM management unit 112 (see FIG. 2) performs the replacement in units of rows associated with the sheet IDs in the manufacturing parts table information 33.

Next, processing when the work procedure displayed on the display device 25 is changed will be described.
FIG. 9 is a flowchart showing the flow of work processing at the cell work terminal after the work instruction screen is replaced. Reference is made to FIG. 2 as appropriate. When the administrator needs to change the work procedure, the instruction sheet replacement command is issued from the input device 13 of the instruction management terminal 10. The instruction management unit 111 determines a sheet replacement instruction (step S1), and in the case of an instruction sheet replacement instruction (step S1, Yes), the instruction information 32 is replaced (step S2), and BOM management is performed. The unit 112 is notified of a sheet replacement command. Next, the BOM management unit 112 that has received the notification of the sheet replacement command replaces the manufactured parts table information 33 (step S3). Specifically, the replacement is performed in units of rows associated with the sheet ID of the manufacturing parts table information 33 shown in FIG. As a result, the manufacturing parts table information 33 is not created again, but the replacement processing time for each row is sufficient. If it is not an instruction sheet replacement command in step S1 (step S1, No), the process returns to step S1 and waits for an input instruction from the input device 13.

  In step S3, if a picking list has already been created based on the manufactured parts table information 33, the BOM management unit 112 performs replacement in units of rows associated with the sheet ID of the manufactured parts table information 33. The picking list is automatically changed in the order of changing the sheet ID.

  The BOM management unit 112 determines a component layout command (step S4), and if the component layout command is selected (step S4, Yes), outputs a picking list (step S5). When outputting the picking list, the picking ID and the sheet ID are stored in the sheet specifying IC tag 61 (see FIG. 2) which is a picking tag. Then, the BOM management unit 112 notifies the picking command and the serving command to the mobile terminal owned by the serving staff. In step S4, if it is not a component layout command (step S4, No), the process returns to step S4 and waits for an input instruction from the input device 13.

  Upon receiving the notification, the dispatcher picks parts from the warehouse based on the picking list, and supplies (distributes) the parts to the parts box 232 at the designated work place position and BOX position (step S6). At this time, the sheet specifying IC tag 61 is also placed in the corresponding component box 232. The staff member puts a plurality of empty parts boxes 232 on the cart, goes to the warehouse, puts a predetermined sheet identifying IC tag 61 for each parts box 232, and picks the picked parts based on the picking list. You may put in the corresponding component box 232. In this case, the staff member may replace the parts box 232 at the designated work site position.

  On the other hand, when the database server 30 receives the information from the cell work terminal 20, it determines whether or not it is the detection of the insertion of the instruction 50 in the work management box 21 (step S7). If it is detected that the instruction 50 has been input (step S7, Yes), the database server 30 determines whether or not the work place position information, the BOX position information, and the sheet ID included in the input command match the instruction information 32. Appropriateness is determined (step S8). When the component arrangement is appropriate (step S8, Yes), the process proceeds to step S9. When the component arrangement is not appropriate (No at Step S8), a warning that the component arrangement is not appropriate is transmitted to the display device 14 of the instruction management terminal 10 and the display device 25 of the cell work terminal 20 (Step S11), and Step S8. Return to. When the warning that the component arrangement is not appropriate is displayed on the display device 25, the worker performs an operation of confirming the position of the component.

  In step S7, when the input is not detected (No in step S7), the process returns to step S7. In step S8, when the component arrangement is not appropriate (step S8, No), a warning may be sent to the mobile terminal of the staff member in step S11.

  In step S9, the database server 30 sequentially displays the work procedure on the display device 25. Upon receiving the information from the cell work terminal 20, the database server 30 determines whether or not it is the detection of the removal of the instruction 50 in the work management box 21 (step S10), and when the removal is detected (step S10, Yes). ), A series of work ends. When it is not detection of removal (No at Step S10), the process returns to Step S10.

  FIG. 10 is an explanatory diagram illustrating a display screen example of the work progress status of the display device. In FIG. 10, the same components as those in FIG. The assembly instruction information 2513 includes a procedure, work content, and detailed work time 2519. In the work start date / time / work end date / time 2515, the time when the instruction 50 is input into the work management box 21 (see FIG. 2) 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 (see FIG. 2) 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 switch 26 (see FIG. 2) is pressed.

And having.

  When the first IC tag reader reads the first IC tag, the work terminal transmits the read information to the management server (for example, step S7), and the second IC tag reader reads the second IC tag. When the tag is read, the sheet ID and the component box position information assigned to the lamp are associated with each other and transmitted to the management server.

  The management server matches the received component box position information and sheet ID of the second IC tag with the received component box position information and sheet ID of the first IC tag out of the instruction information registered in the storage unit. If the determination does not match (for example, step S8), the work terminal is warned that the parts are not properly arranged (for example, step S11), and the work terminal determines that the determination matches. The work procedure of the instruction information registered in the storage unit of the management server is received, the screen information including the received work procedure is displayed on the display unit (for example, the display device 25), and the work is performed based on the work procedure. The lamp corresponding to the component box position information for each procedure can be turned on (for example, step S9).

According to this embodiment, it has the following characteristics.
(1) Linkage of instruction screen information (for example, information associated with the sheet ID of the instruction information 32) and manufacturing parts table information (for example, manufacturing parts table information 33), which is work procedure information for assembling the work target article By doing so, the work efficiency can be improved. Specifically, the manufactured parts table information 33 includes part information for each sheet ID. For this reason, when the work procedure of the instruction screen information on the display device 25 needs to be changed, the instruction management unit 111 changes the sheet ID row of the instruction information 32, and the BOM management unit 112 The manufacturing parts table associated with the sheet ID of the manufacturing parts table information 33 can be replaced.

(2) The picking list is output in order for each part table of the sheet ID, and the picked parts group is allocated to the parts box 232 arranged on the cell work table 71 in association with each sheet ID in order. . In the database server 30 (management server), the information including the arranged sheet ID, the work place position information, and the box position information (BOX position information) of the component box 232 transmitted from the cell work terminal 20 matches the instruction information 32. It is possible to determine whether or not the arranged parts are properly arranged.

(3) The cell work terminal 20 can present the work procedure information on the display device 25 and can turn on the lamp 233 corresponding to the BOX position information associated with the instruction screen information that is each work procedure information. . Thereby, the worker can easily take out the parts necessary for the work. In addition, the worker or the work manager can confirm a work defect such as forgetting to assemble a component depending on the presence or absence of a component in the component box 232 that has already been completed.
