Description

  The present invention relates to a worker support system for supporting a worker on a production line, a worker support method, and a computer program for causing a computer to perform worker support.

  In recent years, due to factors such as diversification of customer requirements, production lines have shifted from low-volume production to multi-variable production. In multivariate production, various products are manufactured on the production line, and workers working on the production line can handle various processes and production operations in order to cope with various product processes and production operations. Need to acquire special skills. However, since there are a limited number of workers who have acquired various skills corresponding to such multivariate production, there is a problem of lack of worker skills and personnel at the production site. For this reason, a skilled worker who has been educating and instructing a young worker as an instructor or educator may be placed on the production line. This makes it difficult for a skilled worker to give sufficient guidance to a worker who lacks skills such as a young worker. On the other hand, when skilled workers are assigned to education or guidance of young workers, there is a problem that the progress of the work is delayed because the number of workers is insufficient by the number of skilled workers who are instructed.

  Various techniques for solving the above problems have been proposed. For example, in Patent Literature 1, skill data indicating the proficiency level of work in each process of each worker is standardized into a database, and by searching for workers who can work based on this skill data, An operator education system for arranging workers is disclosed. In this worker education system, an education schedule based on self-learning is provided as needed to acquire skills necessary for workers based on skill data and production line input plans. In addition, this worker education system distributes an educational tool that can be self-learned by each worker to each terminal so that many workers can simultaneously learn themselves. According to this worker education system, workers having appropriate skills can be placed on the production line. In addition, since the worker can acquire the skills necessary for the work by self-learning, it is possible to save the human burden and time burden relating to education.

Here, positive and negative are represented by white triangles and black triangles, but may be represented by other symbols (for example, “+” and “−”, and upward and downward arrows).

  The work check sheet screen D2 is provided with a work record registration unit T201 that displays a list of work items for each process. The work record registration unit T201 includes a work item number F201 indicating the order of work items, a work item name F202 in which work item names are displayed, a remark F203 in which points to be noted at the time of work for each work item, and the work. A criterion F204 for displaying a criterion for determining whether or not the work is appropriate, a work result value input field F205 for inputting a value indicating a work result for determining whether or not the work is appropriate, and a work Standard work time F206 in which the standard work time for each item is displayed, actual work time F207 in which the actual work time of the completed work item is displayed, and work results in which the past work results of the worker for each work item are displayed. Time F208 is displayed. Here, the work item number F201, the work item F202, the remarks F203, the determination standard F204, and the standard work time F206 include the work item number 202b, the work item name 202c, the remarks 202f, the determination standard 202d, and the standard work time F206. The value stored in each standard work time 202e is displayed. Based on the value stored in the determination criterion 202d of the process information table 202, one of a check box, a numerical value input box, and a pull-down menu is displayed in the work result value input field F205. For example, when a numerical value is a criterion such as “discharge pressure is 30 MPa or less”, a numerical value input box is displayed in the work result input field F205. When the determination criterion is a confirmation prompt such as “don't forget to tighten”, a check box is displayed in the work result input field F205. In addition, when the determination criterion is to select an appropriate one from a plurality of options such as “set to software of v3.1”, the work result input field F205 is pulled down so that a plurality of options can be selected. A menu is displayed. In the present embodiment, the work record input field F205 that has received the input of the work record does not accept the re-input of the work record. Of the work items that have not yet received the input of work results, only the work item with the smallest work item number F201 accepts the input of work results. In the work performance time F208, the average work time, the shortest work time, and the longest work time of the worker for each work item are displayed based on the work performance of the worker stored in the work performance information table 206.

  In addition, the work check sheet screen D2 includes a skill update button B201 for starting the skill update process, a material registration button B202 for starting the material registration process, and a work for starting the delayed worker support process. A support button B203, a work start button B204 for starting the work time count, and a break button B205 for temporarily stopping the work time count are provided.

  When the work check sheet screen D2 is displayed on the input / output unit 31f, the operator operates the input / output unit 31f and presses the work start button B204 on the work check sheet screen D2. When the work start button B204 is pressed, work result registration processing is started. FIG. 12 is a flowchart showing a procedure of work record registration processing executed by the worker support system 1 according to the present embodiment. When the work record registration process is started, the CPU 31a starts counting work time (step S101), and accepts input of work record values in the work record entry field F205 of the work record registration unit T201 (step S102). The work time counted here is displayed as the actual work time on the own station progress information display section L204. A value obtained by subtracting the counted work time from the standard work time set for each work item is displayed as the remaining work time on the own station progress information display unit L204.

  After pressing the work start button, the worker proceeds with the work while referring to the work item F202, the remarks F203, and the determination criterion F204 of the work record registration unit T201. Each time the work of each work item displayed in the work performance registration unit T201 is completed, the worker operates the input / output unit 31f and inputs the work performance of the work item for which the work has been completed in the work performance input field F205. . Here, when the input of the work record value in the work record input field F205 is received, the CPU 31a compares the determination criterion with the input work record value and determines whether or not the work has been properly completed (step). S103). For example, when the criterion is “discharge temperature is 80 ° C. or lower”, it is determined whether or not the value input to the work performance value is 80 or less, and the value input to the work performance value is 80 or less. If so, it is determined that the work has been properly completed. On the other hand, when the value input to the work performance value is not 80 or less, it is determined that the work is not appropriate. Further, when the determination criterion is “set to software of v3.1”, it is determined whether or not the value selected in the work result value matches the software version determined in advance for each model. If they match, it is determined that the work has been properly completed. On the other hand, if they do not match, it is determined that the work is not appropriate. In the case where the determination criterion is “do not forget to tighten”, it is determined that the work has been properly completed when the check box in the work result input field F205 is checked.

  As a result of this determination, if it is determined that the work is not appropriate (NO in step S103), the CPU 31a displays an error screen indicating that the work is not appropriate in the input / output unit 31f (step S104), and displays the result input field. After resetting the input value (step S105), the process returns to step S102, and the registration of work results is resumed. On the other hand, when it is determined that the work is appropriate (YES in step S103), the CPU 31a acquires the work time at the time when the work result is registered as the actual work time (step S106). Next, the CPU 31a transmits to the worker support server 2 work ID information including the worker ID indicating the worker who is working, the process ID and work item number indicating the work item being worked, and the actual work time. (Step S107).

  When the worker support server 2 receives the work record information (step S201), the CPU 21a receives the work record information, including the worker ID, the process ID, the work item number, and the actual work time included in the work record information. At the same time, it is recorded in the work record information table 207 (step S202). Next, the CPU 21a calculates the accumulated work time based on the received work performance information (step S203). A specific calculation method will be described below. First, based on the worker ID and the process ID included in the work performance information, the CPU 21a performs the latest work related to the process identified by the process ID of the worker identified by the worker ID from the work performance information table 206. Identify achievements. Next, the CPU 21a calculates the accumulated work time by adding the actual work time included in the specified work performance and the work time included in the work performance information. Here, when the work item number included in the work performance information is “1”, the most recent work performance is not specified from the work performance information table 206, and the work time included in the work performance information is the accumulated work time. And

  Next, the CPU 21a calculates the accumulated time difference using the accumulated work time calculated in step S203 (step S204). A specific calculation method will be described below. First, based on the process ID and work item number included in the work performance information, the CPU 21a from the process information table 202 to the work item up to the work item identified by the work item number of the process identified by the process ID. Identify standard working hours for each. Next, the CPU 21a adds the specified standard work time, and calculates the accumulated time difference by subtracting the accumulated work time from the added value.

  Further, the CPU 21a calculates a work allowance time using the accumulated time difference calculated in step S204 (step S205). A specific calculation method will be described below. First, based on the process ID and work item number included in the work record information, the CPU 21a specifies the standard work time of the remaining work items of the process identified by the process ID from the process information table 202. Next, based on the worker ID, the process ID, and the work item number included in the work record information, the CPU 21a uses the process ID of the worker identified by the worker ID from the worker record information table 206. All the work results for the remaining work items of the identified process are extracted. Next, the CPU 21a calculates the average value, the longest value, and the shortest value of the actual work time for each work item based on the extracted work results. When these values are calculated, the CPU 21a calculates a value obtained by adding a value obtained by subtracting the sum of the average values of the actual work times from the sum of the specified standard work times and the accumulated time difference, as an average value base margin time, The value obtained by subtracting the sum of the longest actual work time from the sum of the standard time and the cumulative time difference is the longest base margin time, and the sum of the shortest actual work time is the sum of the standard time. The subtracted value is calculated as the minimum value base margin time.

  After calculating these, the CPU 21a temporarily stores the worker ID and process ID included in the work performance information and the calculated work allowance time in the RAM 21c (step S206). Here, when the process ID and the work allowance time are already stored for the same worker ID, the new process ID and the work allowance time are overwritten and stored. Next, the CPU 21a transmits work time information including the accumulated work time, the accumulated time difference, and the work allowance time to the worker client 3 (step S207). When the work client information is received by the worker client 3 (step S108), the cumulative work time, the cumulative time difference, and the work margin time displayed on the own station progress information display unit L204 are updated based on the work time information. (Step S109). Thereafter, the CPU 31a determines whether or not there is still work based on the process chart (step S110). As a result of this determination, if it is determined that there is still work (YES in step S110), the work time count is reset (step S111), the process returns to step S101, and the work time count is started. The processes after S102 are repeated. On the other hand, if it is determined that all work has been completed and there is no more work left (NO in step S110), the work record registration process is terminated.

  In the present embodiment, when the operator operates the input / output unit 31f and presses the break button B205 while the work record registration process is being executed, the CPU 31a displays the time when the break button B205 is pressed. Hold work time and pause work time counting. Further, when the work time count is temporarily stopped, when the work start button B204 is pressed, the CPU 31a resumes the work time count.

(2) Support request processing Next, support request processing will be described. This support request process is automatically started every time the work record information is registered in the work record information table and the work allowance time is calculated in the record registration process described above. Therefore, the support request process is executed in parallel for each of the client clients 3, 3,... Arranged in each of the work stations WS, WS,. A specific processing procedure of this support request processing will be described below.

  FIG. 13 is a flowchart showing the procedure of the support request process executed by the worker support system 1 according to the present embodiment. When the support request process is started, the CPU 21a determines whether or not the work is delayed based on the work allowance time calculated in the above-described result registration process (step S301). More specifically, the CPU 21a determines whether or not the values of the average value base margin time, the shortest value base margin time, and the longest value base margin time calculated in step S205 are 0 or more. As a result, if any of the average value base margin time, the shortest value base margin time, and the longest value base margin time is 0 or more, it is determined that the work is not delayed. On the other hand, if at least one of the average value base margin time, the shortest value base margin time, and the longest value base margin time is less than 0, it is determined that the work is delayed.

  As a result of this determination, if it is determined that the work is not delayed (NO in step S301), the support request process ends. On the other hand, if it is determined that the work is delayed (YES in step S301), the CPU 21a selects the work station to which the work record information received in the work record registration process is transmitted and the production line on which the work station is arranged. Then, the worker who works at the other work station of the production line is specified (step S302). Next, the CPU 21a acquires all skill information in each process of the worker specified in step S302 from the skill information table 204 (step S303). Based on the worker skill information acquired in step S303, the CPU 21a extracts the worker having the highest skill average value (step S304). Thereafter, the CPU 21a transmits a support request to the worker client 3 of the work station where the worker extracted in step S304 is working (step S305), and ends the process. Here, the worker client 3 receiving the support request outputs a warning notifying that a work delay has occurred from the input / output unit 31f. Here, as a warning output method, various methods such as displaying a warning screen, outputting a sound such as a buzzer sound, or a combination thereof can be considered.

  As described above, in this embodiment, the actual work time is measured for each work item in each process, the work delay is determined based on the work time, and information indicating that the work delay has occurred is transmitted. Is configured to do. Thereby, a work delay can be found quickly, and a significant work delay can be prevented. Further, in the present embodiment, information on each work station WS, WS,... Such as the work time can be shared between the work stations WS, WS,. It is configured. Thereby, each worker can confirm and grasp the worker whose work is delayed, and work support for the worker whose work is delayed can be promoted.

(3) Delayed worker support processing Next, the delayed worker support processing executed after the worker client 3 receives the support request transmitted in the above-described support request processing will be described. In the following, the work is delayed and the worker who needs to receive support is “delayed worker”, receives the support request by the above-described support request processing, instructs execution of the delayed worker support processing, and performs the delayed work. The worker who provides support to the worker is referred to as “support worker”, and the worker who is instructed by the support worker to assist the delayed worker is referred to as “support worker”. The delayed worker support process according to the present embodiment includes (3-1) a work assistant request transmission process for selecting an assistant worker and transmitting a work assistance request to the assistant worker, and (3-2) a delay. This can be divided into material transmission processing for transmitting information indicating materials to be used as reference for work to the worker.

  First, the support worker who has received the support request through the support request process operates the input / output unit 31f of the worker client 3 and presses the work support button B203 on the work check sheet screen D2, thereby working the screen display. Switch to the support screen. 14A and 14B are diagrams illustrating an example of a work support screen. On the work support screen, a support method selection unit D3 and detail selection units D4 and D5 are provided. The support method selection unit D3 is provided with a work assistance request button B301 and a material transmission button B302, and the detail selection units D4 and D5 are displayed when the work assistance request button B301 or the material transmission button B302 is pressed. The contents are switched. Here, FIG. 14A is a screen example of a work support screen when the work assistance request button B301 is pressed. The detail selection unit D4 includes an auxiliary worker selection field F401 for selecting an auxiliary worker. A delayed worker field F402 for selecting a delayed worker and a request transmission button B401 are provided. FIG. 14B is a screen example of the work support screen when the material transmission button B302 is pressed, and the detail selection unit D5 displays a material selection field for selecting a material to be transmitted to the delayed worker. F501, a delayed worker column F502 for selecting a delayed worker, and a material transmission button B501 are provided. When the work assistance request button B301 is pressed, the work assistance request transmission process is executed, and when the material transmission button B302 is pressed, the material transmission process is executed. These processes will be described below.

(3-1) Work assistance request transmission process First, the work assistance request transmission process will be described. The work assistance request transmission process is started when the support worker operates the worker client 3 and presses the work assistance request button B301. FIG. 15A is a flowchart illustrating a procedure of work assistance request transmission processing executed by the worker support system 1 according to the present embodiment. When the work assistance request transmission process is started, the CPU 31a transmits auxiliary worker candidate request data to the worker assistance server 2 in order to select a worker to be an auxiliary worker (step S401). When the worker support server 2 receives the auxiliary worker candidate request data (step S501), the CPU 21a first identifies the worker currently engaged in the work (step S502). Next, CPU21a extracts the worker who has a fixed skill about the process in which the delay worker is engaged from the worker specified by step S502 (step S503). The details of step S503 will be described. First, the CPU 21a obtains from the skill information table 204 information that matches the worker ID of the worker identified in step S502 and the process ID of the process in which the delayed worker is engaged. Search and specify the skill value related to the process of each worker. Next, the CPU 21a extracts only the workers whose skill value of each worker specified here is “skilled”.

  Next, the CPU 21a further extracts, from the workers extracted in step S503, workers having a work margin time that can be supported (step S504). Specific processing will be described below. First, the CPU 21a searches for the worker ID of the worker extracted in step S503 from the work margin time temporarily stored in the RAM 21c, and specifies the average value base margin time of each worker. Next, the worker ID of the delayed worker is searched from the work margin time temporarily stored in the RAM 21c, and the average value base margin time of the delay worker is specified. The average base margin time of each worker identified here is compared with the absolute value of the average base margin time of the delayed worker, and the average base margin is greater than the absolute value of the average base margin time of the delayed worker. An operator whose time is a large value is extracted. Next, the CPU 21a transmits auxiliary worker candidate information including the worker ID indicating the extracted worker and the worker name to the worker client 3 of the supporting worker (step S505).

  When the worker client 3 receives the auxiliary worker candidate information (step S402), the CPU 31a updates the detail selection unit D4 on the work support request screen (step S403). Here, as described above, the auxiliary worker selection field F401, the delayed worker selection field F402, and the request transmission button B401 are displayed in the detail selection unit D4. In this case, the name of the delayed worker is automatically displayed in the delayed worker column F402. In the auxiliary worker selection field F401, information indicating the worker included in the auxiliary worker candidate information is displayed in a pull-down format. When the detail selection unit D4 is updated, the support worker operates the input / output unit 31f, selects an auxiliary worker from the auxiliary worker selection field F401, and then presses the request transmission button B401. When the request transmission button B401 is pressed, the CPU 31a transmits selected auxiliary worker information including the worker ID indicating the worker selected in the auxiliary worker selection field F401 to the worker support server 2 (step S404). . When the worker support server 2 receives the selected auxiliary worker information (step S506), the CPU 21a identifies the work station on which the auxiliary worker is working based on the worker ID included in the selected auxiliary worker information. , Information indicating the production line and work station on which the delayed worker is working, and the average base margin of the delayed worker and the name of the delayed worker for the worker client 3 installed in the work station The work assistance request information including time is transmitted (step S507), and the work assistance request transmission process is terminated.

  When the worker client 3 receives the delayed worker information, the CPU 31a causes the input / output unit 31f to display a work assistance request screen based on the received work assistance request information. FIG. 16A is a diagram illustrating a screen example of the work assistance request screen D6. On the work assistance request screen, information including the name of the delayed worker and the absolute value of the average value base margin time is displayed. After confirming this display, the auxiliary worker goes to work assistance for the delayed worker, and performs work assistance such as guidance within the displayed average value base margin time.

  Thus, in this Embodiment, it is comprised so that the candidate of an auxiliary | assistant worker may be selected based on an operator's actual working time. For this reason, a worker who can afford work assistance such as guidance can be selected as a supplementary worker, and it is possible to prevent the work delay of the supplementary worker due to work assistance such as guidance to the delayed worker. it can. Moreover, in this Embodiment, it is comprised so that a worker with the skill which concerns on the process which a delay worker engages in a certain level or more may be selected as a candidate for an auxiliary worker. For this reason, the worker who has an appropriate skill for performing work assistance such as guidance can be selected as the auxiliary worker. In the present embodiment, since the worker is directed to the work station where the delayed worker is actually working and performs work assistance such as guidance in the field, OJT (On-the-Job) is combined with work support. Training) format education.

  In the present embodiment, the support worker may select himself as an auxiliary worker. In this case, the support worker may go to the work assistance of the delayed worker without executing the work assistance request transmission process.

(3-2) Material Transmission Process Next, the material transmission process will be described. The material transmission process is executed when the support worker operates the worker client 3 and presses the material transmission button B302. FIG. 15B is a flowchart showing a procedure of a material transmission process executed in worker support system 1 according to the present embodiment. When the material transmission process is started, the CPU 31a transmits candidate material request data to the worker support server 2 in order to select a material suitable for the work support of the delayed worker (step S601). When the worker support server 2 receives the candidate material request data (step S701), the CPU 21a selects a material suitable for transmission as work support based on the skill information of the delayed worker (step S702). . Specific processing will be described below. First, the CPU 21a acquires the model ID and the process ID in the process in which the delayed worker is currently engaged. Next, the acquired model ID and process ID are searched from the material information table 205, and the material relating to the model and process is extracted. Next, the CPU 21 a acquires the skill value related to the process in which the delayed worker is currently engaged from the skill information table 204. Next, the CPU 21a compares the extracted reference skill for each material with the skill value of the delayed worker, and selects a material that matches these as a candidate material. Next, the CPU 21a transmits candidate material information including the material ID and material name of the selected material to the worker client 3 (step S703).

  When the candidate material information is received by the worker client 3 (step S602), the CPU 31a updates the display of the detail selection unit D5 on the work support request screen and accepts the selection of the material (step S603). Here, as described above, the material selection field F501, the delayed worker selection field F502, and the material transmission button B501 are displayed in the detail selection unit D5. In the delayed worker column F502, the name of the delayed worker is automatically displayed. In the material selection field F501, information indicating materials included in the material candidate information is displayed in a pull-down format. When the detail selection unit D5 is updated, the operator operates the input / output unit 31f, selects a material from the material selection field F501, and then presses the material transmission button B501. When the material transmission button B501 is pressed, the CPU 31a transmits selected material information including a material ID indicating the selected material to the worker support server 2 (step S604). When the worker support server 2 receives the selected material information (step S704), the CPU 21a receives the support material information including the name and address of the selected material based on the material ID included in the selected material information. Is transmitted to the worker client 3 of the work station that is working (step S705), and the material transmission process is terminated.

  When the worker material 3 receives the support material information, the CPU 31a displays a material reception screen on the input / output unit 31f based on the received support material information, and ends the processing. FIG. 16B is a diagram illustrating a screen example of the material reception screen D7. On the material reception screen D7, the name of the material included in the support material information and an access button B701 for accessing the material are displayed. The delayed worker operates the input / output unit 31f and presses the access button B701 to access the material transmitted as support material information, and the material is displayed on the input / output unit 31f. The delay worker recovers the delay in the work by proceeding with the work while referring to the displayed material.

  As described above, in the present embodiment, a skill necessary for referring to each material is set, and a material candidate to be transmitted is selected based on the skill of the delayed worker. For this reason, a delay worker can be referred to appropriate materials.

(4) Skill Update Processing Next, skill update processing for updating and registering the skill information of the worker registered in the skill information table 204 will be described. This skill update process is executed when it is determined that the skill of the worker has been improved by receiving work support by the above-described delayed worker support process. This determination is performed by another worker (for example, a support worker or an auxiliary worker) based on a situation in which a worker (for example, a delayed worker) is actually working. In addition, after the work support is provided to the delayed worker by the delayed worker support process, is the work time of the delayed worker increased from the work station progress information display portion L203 of the work check sheet screen D2? By confirming whether or not, the support worker or the auxiliary worker may determine whether or not the skill of the delayed worker has improved.

  A worker who executes the skill update process operates the input / output unit 31f of the worker client 3, presses the skill update button B201 on the work check sheet screen D2, and performs a skill update registration screen for performing skill update registration. Is displayed on the input / output unit 31f. FIG. 17 is a diagram illustrating a screen example of the skill update registration screen D8. The skill update registration screen D8 includes an operator selection field F801 for selecting an operator whose skill is to be updated, a process selection field F802 for selecting a process for updating the skill, and the worker selected in the worker selection field F801. A current skill display field F803 in which the current skill level relating to the process selected in the process selection field F802 is displayed, a review skill selection field F804 for selecting a skill to be updated and registered, and a registration button B801 are provided. Here, the worker name registered in the worker information table 203 is displayed in the worker selection field F801, and the model name and process registered in the model information table 201 are displayed in the process selection field F802. In F804, “young”, “mid-level”, and “skilled” values are displayed in a pull-down format. The operator operates the input / output unit 31f and selects an operator and a process whose skill is to be updated from the worker selection field F801 and the process selection field F802. When these are selected, the worker client 3 accesses the worker support server 2, acquires skill information indicating the skill of the worker in the process from the skill information table 204, and uses the acquired skill information as the current skill. Displayed in a display field F803. After confirming the skill displayed in the current skill display field F803, the operator operates the input / output unit 31f and inputs a new skill in the review skill selection field F804. The worker inputs new skill information in the worker selection field F801, the process selection field F802, and the review skill selection field F804, and then presses the registration button B801. As a result, the input skill information is transmitted to the worker support server 2 and updated and registered in the skill information table 204.

  As described above, in this embodiment, the operator's skill is confirmed by confirming the state of the worker's actual work or confirming whether or not the time required for the worker is shortened. It is determined whether or not the skill level has improved, and skill update registration is performed according to the result. For this reason, it is possible to appropriately set and register skills that each worker actually possesses. In the present embodiment, the work supporter is selected and the transmission material is selected based on the appropriate skill information. Therefore, more appropriate support can be provided to the delayed worker.

(5) Material Registration Processing Next, material registration processing for additionally registering new materials in the material information table 205 will be described. This material registration process is for additionally registering materials from the worker client 3. The worker who executes the material registration process operates the input / output unit 31f of the worker client 3, presses the material registration button B202 on the work check sheet screen D2, and inputs / outputs the material registration screen for performing material registration. It is displayed on the part 31f. FIG. 18 is a diagram illustrating a screen example of the material registration screen D9. The document registration screen D9 includes a model selection field F901 for selecting a model, a process selection field F902 for selecting a process for each model, and a reference skill selection field F903 for selecting an appropriate skill for referring to the material. A material name input field F904 for inputting a material name, an address input field F905 for inputting a file address, and a registration button B901 are provided. Here, in the model selection column F901 and the process selection column F902, the model ID registered in the model information table 201 and the process for each model are displayed, and in the reference skill selection column, “young”, “mid-level”, and “skilled”. Each value is displayed in a pull-down format. The operator operates the input / output unit 31f, inputs new material information into the model selection field F901, the process selection field F902, the reference skill selection field F903, the material name input field F904, and the address input field F905 for registration. Button B901 is pressed. As a result, the input material information is transmitted to the worker support server 2 and additionally registered in the material information table 205.

  As described above, in the present embodiment, the worker client 3 can register the material that serves as a reference for the work. For this reason, an operator can photograph the state of actual work with a digital camera or the like, and register materials created based on the photograph. By registering such materials, it is possible to promote Pokayoke or Kaizen from the field. Further, in the present embodiment, since materials can be registered from the operator client 3, materials created by the worker can be immediately registered from the site. This makes it possible to share points of caution during work that the worker has noticed in real time.

(Other embodiments)
The worker support system 1 according to the embodiment described above is configured to start the delayed worker support process by receiving an instruction to start execution from the support worker, but the present invention is limited to this. is not. For example, when it is determined that there is an operator whose work is delayed in the preceding support request process, the delayed worker support process may be automatically started. In this case, in the work assistance request transmission process, the worker support server 2 selects the worker having the highest skill and the largest work allowance time based on the skill and work allowance time of each worker. It is preferable to select automatically as a person. Further, in the material transmission process, it is preferable that the worker support server 2 automatically selects based on the process engaged by the delayed worker and the skill of the process. In addition, either the work assistance request transmission process or the material transmission process may be automatically started. First, the work assistance request transmission process is started, and a candidate for an auxiliary worker is found in the work assistance request transmission process. If not, the material transmission process may be started. In addition, in the support request process, the work manager who manages the entire work operates the worker support server 2 or the client for the work manager to start the support request process arbitrarily. The result may be displayed on the work support server to the work manager. In this case, the work manager determines whether or not the work support should be performed based on the result, and if it determines that the work support should be performed, the work manager issues a work support request and starts the delayed worker support process. It is conceivable to instruct the person support system 1.

  In the above-described embodiment, the worker support system 1 is configured to transmit work assistance request information via the worker support server 2 in the work assistance request transmission process. Is configured to transmit support material information via the worker support server 2, but the present invention is not limited to this. For example, the worker support system 1 sends the worker client 3 at the work station WS of the support worker to the worker client 3 at the work station WS of the auxiliary worker or the delayed worker via the information network NTW. The work assistance request information or the support material information may be directly transmitted.

  In the embodiment described above, the worker support system 1 provides support request information to the worker with the highest average skill value on the production line on which the delayed worker is working in the support request process. Although configured to transmit, the present invention is not limited to this. For example, a worker who becomes a supervisor is determined in advance for each production line, and the worker support system 1 transmits support request information to the worker client 3 of the supervisor work station WS in the support request processing. May be. Moreover, you may be comprised so that support request information may be transmitted with respect to the client clients 3, 3, ... of all the work stations WS, WS, ... in which workers other than a delay worker engage.

  In the above-described embodiment, a server program dedicated to the worker support system is installed in the worker support server 2, and a client program dedicated to the server program is installed in the worker client 3. Although the configuration in which the unique format data is transmitted to each client 3 has been described, the present invention is not limited to this. The worker support server 2 may have a function as a WWW server and transmit HTML data to the worker client 3 as a WWW client device.

  In the above-described embodiment, the configuration in which all processing of the computer program 24a is executed by the single computer 2a has been described. However, the present invention is not limited to this, and processing similar to that of the computer program 24a described above is performed. It is also possible to make a distributed system in which a plurality of devices (computers) are executed in a distributed manner.

  A worker support system, a worker support method, and a computer program according to the present invention provide a worker support system, a worker support method, and a computer for supporting a worker who performs production work on a production line. It is useful as a computer program or the like.
