FIG. 1 is an overall configuration diagram showing a work performance collecting system according to the present embodiment. The work record collection system S includes an instruction management terminal 10, a cell work terminal 20 (work terminal), and a database server 30 (management server). The instruction management terminal 10, the cell work terminal 20, and the database server 30 are connected by a network 40 such as a LAN (Local Area Network).

  In the present embodiment, a cell production system work process in which one or several workers are in charge of a plurality of works will be described as an example. In the cell production method, work is performed on a cell work table 71 called a cell in which parts and tools are arranged. The major advantage of the cell production method is that it is easy to change the production items (product variations, etc.) simply by changing the parts box and changing the work order of the workers in the cell. . In addition, the production volume can be easily adjusted by adjusting the number of people in the cell or by increasing or decreasing the number of cells.

  The instruction management terminal 10 is a computer terminal that issues / manages instructions 50 when work is required, and registers instruction contents and assembly instruction information in the storage unit 31 of the database server 30. The assembly instruction information is information on parts and procedures necessary for assembling (assembling) a product or semi-finished product. Here, as an example of the assembly instruction information, an assembly process for assembling the component 73 to the electronic circuit board 74 (work object) is taken as an example.

  The instruction management terminal 10 includes a processing unit 11, an input device 13, a display device 14, an IC tag reader / writer 15, and a printer 16, and the processing unit 11 includes an instruction management unit 12 that manages the instructions 50.

  Upon receiving an instruction output request from the input device 13, the instruction management unit 12 outputs an instruction 50, which is a rewritable sheet, by the printer 16 having a rewritable function. At that time, the IC tag reader / writer 15 writes information for specifying the work content in the work specifying IC tag 51 in accordance with an instruction from the instruction management unit 12.

  The information for specifying the work content is, for example, the instruction ID of the instruction 50, the product name or model number of the product / semi-product to be manufactured, the number of producers, etc. In addition, as detailed information of information specifying the work content of the work target article, assembly information when the worker assembles the component 73 on the electronic circuit board 74 is described. Specifically, the type of the component 73 is described. , Number, and assembly order of parts.

  The instruction 50 is a document in which an assembling process corresponding to the worker is described. Specifically, there are various types of components 73 as components to be assembled to the electronic circuit board 74. In the instruction 50, a process route (normal route) for assembling and creating the component 73 on one electronic circuit board 74 is shown. Is described. For example, there are a CPU (Central Processing Unit) process, a CPU peripheral component process, a power supply process, and an I / O interface process. The operator can determine the route of the work process based on the instruction 50. The work identification IC tag 51 uses a non-contact wireless IC tag such as RFID (Radio Frequency IDentification) and is attached to the document of the instruction 50.

  The cell work terminal 20 displays a work management box 21 (IC tag placement location) having an insertion slot, an IC tag reader / writer 22 attached to the side of the work management box 21 to read the work identification IC tag 51, and a work instruction. The display device 25 to be switched, the switch 24 for the operator to switch the work procedure displayed on the display device 25, the infrared thermography device 23 for acquiring the temperature distribution image of the predetermined area of the cell work table 71, and the cell work terminal 20. And a control device 26 that controls the above.

  The work management box 21 is a box in which an operator inputs an instruction 50 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.

  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 device 26. 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 ID of the instruction 50, the model number of the product / semi-product to be manufactured, and the number of production personnel. When the IC tag reader / writer 22 confirms the disconnection of communication with the work identification IC tag 51 when the instruction 50 is taken out from the work management box 21, the IC tag reader / writer 22 identifies the work identification to the database server 30 via the control device 26. 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 ID of the instruction 50, the model number of the product / semi-product to be manufactured, 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 device 26 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 infrared thermography device 23 is installed above the cell work table 71 and faces the cell work table 71. The infrared thermography device 23 detects the infrared radiation energy emitted from the object, converts it to an apparent temperature, measures the temperature distribution on the cell work table 71, and colors the measured temperature distribution for each temperature. This is a device for imaging. A temperature distribution image obtained by imaging the measured temperature distribution is generated and transmitted to the control device 26 as a video signal. Based on the temperature distribution image received from the infrared thermography device 23, the control device 26 determines whether or not the operator's hand is within a predetermined area of the cell work table 71, and the presence or absence of the hand in the predetermined area Detailed work time determination processing in the work process is performed. Details of the processing will be described with reference to FIGS.

  FIG. 2 is a block diagram showing the configuration of the control device of the cell work terminal. The control device 26, which is a computer device, includes a temperature distribution image acquisition unit 261 that acquires a temperature distribution image from the infrared thermography device 23, and an image determination unit that determines whether there is a human hand in a predetermined area of the cell work table 71. 262, a work time accumulation unit 263 that accumulates work time as invalid work when there is no human hand and as valid work when there is a human hand. Here, the work time of invalid work is defined as invalid work time, and the work time of valid work is defined as valid work time.

  The image determination unit 262 performs image processing on the temperature distribution image acquired by the temperature distribution image acquisition unit 261. For example, when the area equal to or higher than the human body temperature is equal to or less than a predetermined value, a hand is placed in the predetermined region. Judge as not.

  FIG. 3 is an explanatory diagram showing a work time integration method. An example of the process of the invalid work time accumulation method of the work time accumulation unit 263 is shown. The work time accumulation unit 263 starts accumulation of invalid work time when the switch 24 is pressed (operated) to notify the end of the previous work process in a plurality of work processes. If the image determination unit 262 determines that there is a hand, “1”, otherwise “0”, the work time integration unit 263 integrates the time when the image determination unit 262 is “0”, and then The integration process is continued until the switch 24 is pressed (operated). FIG. 3 shows an accumulated state of invalid work time.

The work time integrating unit 263 calculates the effective work time Tp by the equation (A1) as the invalid work time Tq at the time when the integration process is completed.
Tp = T2-T1-Tq (A1)

  Then, the work time integrating unit 263 associates the instruction ID, the process ID, and the assembly instruction information (sheet ID) (see FIG. 5) with the effective work time Tp and the work ID of the work corresponding to the sheet ID. The detection time of pressing (for example, T2) is transmitted to the database server 30. The work time accumulating unit 263 transmits the effective work time Tp and the like to the database server 30, but the control device 26, which is a control unit, controls the instruction ID, process ID, and assembly instruction information (sheet ID). The effective work time Tp or the like may be transmitted in association with (see FIG. 5).

  In the examples of FIGS. 2 and 3, the invalid work time is obtained and the effective work time is obtained from the equation (A1), but is not limited to this. If the image determination unit 262 determines that there is a person's hand as “1”, the work time integration unit 263 can obtain the effective work time by integrating the time at that time.

  Returning to FIG. 1, the database server 30 is a server that stores the instruction information of the instruction 50 and the work result information based on the instruction 50 in the storage unit 31 and analyzes the work result information. The instruction management terminal 10 and the cell work terminal 20 Remember the information from.

  When the database server 30 receives information from the cell work terminal 20, for example, 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. When the time information is not included in the information transmitted from the IC tag reader / writer 22, the time information (time stamp) added to the received information is used for managing the received information. A processing unit (not shown) of the database 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.

  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 instruction 50 and the work results in the manufacturing process from the administrator terminal (not shown) of the database server 30, Can be monitored and analyzed.

  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 boxes 75 are installed in front of the worker. The display device 25 is placed on 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.

  As described above, the infrared thermography device 23 is installed above the cell work table 71 and generates a temperature distribution image of a predetermined region of the cell work table 71. A camera 23C (not shown) in the infrared thermography device 23 is a camera having a structure in which the photographing direction is variable, and also has a zoom function. The camera 23C can receive an instruction from the database server 30 (management server) and take a picture based on the instructed camera angle and zoom magnification.

  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 24 of the cell work table 71 is pressed, a screen for the next sheet ID is displayed. For example, every time the operator presses the switch 24 (see FIG. 4), the contents of the work instructions with the sheet IDs B0002, B0003, B0004, B0005, and B0006 are displayed in order.

  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 / semi-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 detailed work time 2518. For example, the work content when the procedure (sheet ID) is B0001 is “work guidance”, the work content when the procedure is B0002 is “Parts 001 attachment”, and the work content when the procedure is B0003 is “Parts 002 attachment”.

  In the work start date / time and work end date / time 2515, the date and time when the instruction 50 is input into the work management box 21 (see FIG. 2) and the date and time when the instruction 50 is taken out from the work management box 21 are displayed. The completed number 2517 displays the number of completed members out of the number of production members, and when the procedure of the assembly instruction information 2513 is completed, the control device 26 (see FIG. 1) displays the number of completed members.

  The detailed work time 2518 displays the end time of each procedure, and the control device 26 displays the time when the switch 24 (see FIG. 1) is pressed. In this way, the worker can proceed with the work while confirming according to the work content instruction on the display screen of the display device 25 (see FIG. 1).

  The input unit 252 of the display device 25 includes a menu button 253. When the sheet movement is selected, the cursor button 254 is used to change to a work procedure screen for starting work when 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 displays an attachment part field 2521, an overall view field 2522, a detail field 2523, a part information field 2524, a work elapsed time field 2525, a procedure number field 2526, and an interruption button 2527. “O 1 2” shown in the balloon of the detail column 2523 means that the operator takes two connectors from the component box 75 (see FIG. 4) identified by the letters “O 1”. doing.

  The operator can confirm the assembly 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 work is interrupted, the elapsed time can be paused by pressing the interrupt button 2527, but is recorded in the database server 30 as the interruption time during the work time.

Next, processing of the work record collection system will be described with reference to FIGS.
FIG. 7 is a flowchart showing a processing procedure of the work record collection system. When the worker in the work area receives the electronic circuit board 74 to which the instruction 50 is attached, the worker puts the instruction 50 into the work management box 21 installed at the lower part of the cell work table 71. Then, the IC tag reader / writer 22 detects the insertion of the instruction 50 (step S201).

  The IC tag reader / writer 22 reads the detected information of the work specifying IC tag 51, and communicates with the database server 30 via the control device 26, the communication start information with the work specifying IC tag 51, and the work content of the work target article. Is transmitted as work start information (step S202).

  The database server 30 records the received communication start information with the work specifying IC tag 51 and information specifying the work content of the work target article in the storage unit 31 as work start information. Information received at this time is recorded with time information (time stamp) added (step S301).

  The database server 30 transmits the instruction information including the assembly instruction information of the instruction 50 (the sheet screen corresponding to the sheet ID) to the cell work terminal 20 (step S302). When receiving the instruction information, the control device 26 of the cell work terminal 20 displays a sheet screen on the display device 25 in accordance with the procedure of the assembling instruction information (step S203), and starts the invalidation work time integration process (step S203). S204).

  In step S203, the control device 26 may display that the instruction 50 has been received before displaying the sheet screen, and may display a sheet screen that is the first work procedure screen when the switch 24 detects pressing. . Thereby, the start time of the first work procedure (for example, the sheet ID B0001 in FIG. 8) becomes clear. When the switch 24 for starting the work procedure is pressed, the start transmission of the sheet may be transmitted to the database server 30 (not shown in FIG. 7). And the control apparatus 26 performs the integration process of work time (step S204).

  The control device 26 of the cell work terminal 20 determines whether or not the sheet process is finished depending on whether or not the switch 24 is pressed (step S205). When the pressing of the switch 24 is detected (step S205, Yes), Proceed to step S206. When pressing of the switch 24 is not detected (step S205, No), the process returns to step S204.

  In step S <b> 206, the control device 26 of the cell work terminal 20 transmits information indicating that the work of the sheet process is finished (sheet process end information) to the database server 30. Specifically, the information indicating the completion of the work of the sheet process is an instruction ID, a process ID, a sheet ID, attachment completion information, and an effective work time shown in FIG. The database server 30 adds time information (time stamp) to the received information and records it in the storage unit 31 as sheet process end information (step S303).

  The control device 26 of the cell work terminal 20 determines whether or not all the steps of the instruction 50 have been completed (step S207). When the process is not finished (No at Step S207), the process returns to Step S203. When all the processes have been completed (step S207, Yes), the process proceeds to step S208.

  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 cannot be confirmed within the predetermined time, the operator gives instructions 50 and the work management box 21. It is detected that it has been taken out from (step S208). The IC tag reader / writer 22 transmits communication end information (work end information) with the work specifying IC tag 51 to the database server 30 via the control device 26 (step S209).

  When the database server 30 receives the communication end information and the information for specifying the work content of the work target article from the cell work terminal 20, the database server 30 adds time information (time stamp) to the received information as work end information. It records in the memory | storage part 31 (step S304). Thereby, a series of procedures for collecting work results is completed, and work result management information (see FIG. 9) is created (step S305).

  FIG. 8 is an explanatory diagram showing work performance collection information recorded in the storage unit. When the instruction ID is A0001, when the instruction 50 is inserted into the work management box 21, the work is started at time 9:00: 00 (9: 00: 0), and the instruction 50 is sent from the work management box 21. When it is taken out, the work is completed at time 9:07:50 (9: 7: 50). When the instruction ID is A0002, when another instruction 50a is inserted into the work management box 21, the work starts at time 9:09:30, and when the instruction 50a is taken out from the work management box 21, The work is finished at time 9:17:10.

  The details of the instruction ID A0001 are recorded in the storage unit 31 for each part assembling process (sheet ID). For example, the work with the sheet ID B0001 is time 9:00:20 (9: 0: 20) The operation with the sheet ID B0002 ends at 9:00:50, the operation with the sheet ID B0003 ends at 9:04:40, and the operation with the sheet ID B0004 completes at time 9:05: The operation with the sheet ID B0005 ends at time 9:06:50, and the operation with the sheet ID B0006 ends at time 9:07:40. A period between time 9:07:40 and time 9:07:50 is regarded as a dead time until the instruction 50 is taken out from the work management box 21.

  In each sheet detail, the effective work time Tp for each sheet ID is indicated by a hatched portion, and the total effective work time when the instruction ID is A0001 is indicated by a hatched portion at the bottom. Case 1 is a case where each sheet ID is divided into valid work time and invalid work time and stored in the storage unit 31 (see FIG. 1), and Case 2 is a set of valid work time and invalid work time in the sheet ID. This is a case in which the total time is not collected, but is stored in the storage unit 31 so that the repetitive work of the valid work and the invalid work within the sheet ID can be understood. For example, in the case of work B0003, it can be seen that valid work and invalid work are repeatedly performed. In the case of the work B0004, it can be seen that immediately after the work starts, the work is not performed immediately, and the work is performed after a while.

  FIG. 9 is an explanatory diagram illustrating an example of a work performance collection result. In the storage unit 31, as an operation performance collection parameter, an instruction ID, an operation start (date and time), an operation end (date and time), an operation time, an effective operation time, and an effective operation rate that is a ratio of effective operation time to operation time (present Efficiency), process ID, and worker ID are recorded. According to FIG. 9, for example, when the work ID, which is one of the whole work processes W0001, is A0001, the work is started at time 9:00: 00 by the worker MS001 on May 10, 200X. : It can be seen that the work is completed at 07:50. Further, it can be seen that the work time is 7:50 (7 minutes and 50 seconds), of which the effective work time is 5:48 (5 minutes and 48 seconds), and the effective work rate is 74.0%.

  Similarly, when the instruction ID is A0002, it can be seen that the worker MS002 started work at time 9:09:30 on May 10, 200X and finished at time 9:17:10. . Also, it can be seen that the work time is 8:40 (8 minutes 40 seconds), of which the effective work time is 5:55 (5 minutes 55 seconds), and the effective work rate is 68.3%.

  The processing unit of the database server 30 may notify the display unit or the like when the work result collection result is less than a predetermined effective work rate (for example, the improvement standard is 70% or less). When the administrator refers to the effective work rate displayed on the display unit and compares the worker IDs between MS001 and MS002, MS002 has an effective work rate of 70% or less, and will improve in future work contents. I understand that there is room.

  The cell work terminal 20 of the present embodiment includes a switch 24 that gives a command to switch the work procedure displayed on the display device 25, an infrared thermography device 23 that acquires temperature image information of a predetermined area of the work place, and a control device 26. have. The control device 26 determines whether or not there is a human hand in a predetermined area of the cell work table 71 from the temperature image information acquired by the infrared thermography device 23. Until the operation of the switch 24 is detected, the effective work time is accumulated as the effective work time. After detecting the operation of the switch 24, the control device 26 associates the management identification information (sheet ID) of the work procedure with the effective work time and transmits the work record collection information to the database server 30. The received work performance collection information is recorded in the storage unit 31.

  According to the present invention, the administrator refers to the work record collection information shown in FIG. 8 and the work record collection result shown in FIG. 9, which instruction ID has a problem (is work efficiency poor?) It is possible to easily determine which work procedure (sheet ID) of the instruction ID has a problem, the time of effective work (effective work time) within the work of the instruction ID and the sheet ID, and the like.
