(Findings on which this disclosure is based)
The inventors of the present invention have found that the work management method of Patent Document 1 described in the "Background Art" section has the following problems.

For example, workers in an assembly process or a mounting manual insertion process in a facility equipped with a component mounting apparatus are arranged in an assembly line. In addition, the worker must observe the cycle time of the work he is in charge of together with other workers. In addition, speedy work is required for work that becomes a bottleneck. Concentration is required for work that requires that the leads of electronic components not be bent, and for work such as soldering. In other words, each task not only requires that the worker performing the task is in good physical condition, but may also require sufficient skill. However, in the work management method of Patent Literature 1, even if the physical condition of the worker is taken into account with regard to the details of the work performed by the worker, the skill of the worker is not taken into consideration. Therefore, there is a possibility that work that requires sufficient skill will be assigned to a worker who does not have the skill. As a result, work efficiency cannot be sufficiently improved.

In order to solve such problems, a work management method according to one aspect of the present disclosure is a work management method in which a computer manages a plurality of works in a facility equipped with a component mounting apparatus, The physical condition level is specified, the skill level of the first worker is specified, and among the plurality of works, the work according to the physical condition level and the skill level is selected as the first work to be assigned to the first worker. decide.

As a result, the work according to not only the physical condition level but also the skill level of the first worker is assigned to the first worker as the first work. As a result, it is possible to reduce the possibility of assigning work that requires sufficient skill to a worker who does not have the skill. Therefore, it is possible to suppress the decrease in the production amount of the product produced by the work and to maintain the quality of the product. In other words, work efficiency can be further improved.

Further, in the work management method, biological information indicating a state of the biological body of the first worker, which is measured by a sensor, is acquired, and in specifying the physical condition level of the first worker, the acquired biological body The physical condition level may be specified by comparing the information with basic biometric information indicating a reference state of the biometric condition of the first worker. For example, the basic biometric information may indicate the biometric condition of the first worker when he/she is healthy.

Accordingly, the physical condition level of the first worker can be appropriately specified based on, for example, the difference between the biological information and the basic biological information.

Further, in specifying the physical condition level of the first worker, for each of a plurality of workers, a basic biometric database containing basic biometric information indicating a reference state regarding the biometrics of the worker is referred to, and from the basic biometric database, Basic biometric information of the first worker may be retrieved.

Thereby, the basic biometric information of the first worker can be properly grasped.

Further, in identifying the skill level of the first worker, for each of a plurality of workers, a skill database indicating the skill level of the worker is referred to, and the skill level of the first worker is searched from the skill database. The skill level of the first worker may be specified by doing.

Thereby, the skill level of the first worker can be appropriately specified.

Further, in determining the first work, for each of the plurality of works, the work, the required physical condition level that is the physical condition level required for the work, and the required skill level that is the skill level required for the work. and said required physical condition level and said required skill level corresponding to said physical condition level and said skill level of said first worker among said plurality of tasks shown in said required level database may be determined as the first task.

As a result, the work associated with the required physical condition level and required skill level satisfied by the first worker's physical condition level and skill level is determined as the first work. can be properly executed. As a result, it is possible to improve the working efficiency of the first work.

Further, in the work management method, an identifier for identifying the first worker is further obtained, and in searching for the basic biometric information of the first worker, a plurality of the basic biometric information contained in the basic biometric database is obtained. Among the information, basic biometric information associated with the acquired identifier may be retrieved as the basic biometric information of the first worker.

As a result, since the basic biometric information of the first worker is searched using the identifier of the first worker, erroneous searches can be suppressed.

Further, in the work management method, an identifier for identifying the first worker is further acquired, and in identifying the skill level of the first worker, among the plurality of skill levels shown in the skill database, , a skill level associated with the obtained identifier may be identified as the skill level of the first worker.

As a result, the skill level of the first worker is specified using the identifier of the first worker, so the skill level of the first worker can be specified more appropriately.

In addition, the work management method further specifies a work being executed by the first worker as a work in progress, and in determining the first work, more than the work in progress among the plurality of works. A job requiring a high skill level or a job requiring a low skill level may be determined as the first job.

Thereby, when the skill level of the first worker does not satisfy the skill level required for the work in progress, the work of the first worker is changed from the work in progress to the first work. For example, the work of the first worker is changed to a first work that requires a lower skill level than that of the ongoing work. Therefore, the performance of the first worker can be utilized, and the work efficiency of the entire facility can be improved. Conversely, even if the work of the first worker is changed to the first work that requires a skill level higher than the skill level required for the work in progress, the same is true. It should be noted that the ongoing work does not mean only the work actually being performed by the worker, but means the work that has already been assigned to the worker.

Further, the work management method further specifies the work being executed by the first worker as a work in progress, and in determining the first work, the first work different from the work in progress is determined. In this case, it is decided to change the worker of the work in progress from the first worker to the second worker, and the second worker has the physical condition level and skill required for the work in progress. may have levels.

Thereby, even if the work of the first worker is changed from the work in progress to the first work, the work in progress is not stopped and has the physical condition level and skill level required for the work in progress. It can still be performed by a second operator. Therefore, it is possible to improve the working efficiency of the entire facility.

In addition, the work management method further includes referring to a work management database showing work performed by each of a plurality of workers, thereby allowing at least one worker other than the first worker to identifies the work that is being performed, and the determination of replacement with the second worker includes performing work that requires a lower skill level than the work being performed, of the at least one worker The worker who is present may be determined as the second worker.

As a result, the skill level required for the work being performed by the second worker is lower than the skill level required for the work being performed by the first worker. Therefore, even if the worker of the work in progress is changed from the first worker to the second worker, the work that the second worker was performing can be easily assigned to another worker. Therefore, it is possible to improve the working efficiency of the entire facility.

Further, in the work management method, the physical condition level of each of at least one worker other than the first worker is specified, the skill level of each of the at least one worker is specified, and the plurality of Refer to the required level database that shows the work, the required physical condition level that is the level of physical condition required for the work, and the required skill level that is the skill level required for the work. specifies the required physical condition level and the required skill level of the work in progress, and the physical condition level and the skill level corresponding to the required physical condition level and the required skill level of the work in progress among the at least one worker. may be determined as the second worker.

Thereby, it is possible to appropriately determine the second worker who can execute the work being executed by the first worker in place of the first worker. That is, for the second worker, the ongoing work of the first worker is determined as a new work. In other words, the determination of the first work to be assigned to the first worker is similarly performed for the second worker. In other words, the physical condition level of the first worker is identified, the skill level of the first operator is identified, and among a plurality of tasks, the work corresponding to the physical condition level and skill level is assigned to the first worker. The process of determining the work as the first work is also performed for the second worker.

Further, in the work management method, information indicating the determined first work may be displayed on a display to prompt the first worker to perform the first work.

This allows the first worker to appropriately perform the first work.

Further, in determining the first work, at least one work associated with the required physical condition level corresponding to the physical condition level of the first worker, among the plurality of works shown in the required level database, selecting each work candidate as a first work candidate, and among at least one of the first work candidates shown in the required level database, the work associated with the required skill level corresponding to the skill level of the first worker; It may be determined as the first work. Alternatively, in determining the first work, among the plurality of works shown in the required level database, at least one work associated with the required skill level corresponding to the skill level of the first worker, selected as first work candidates, and among at least one of the first work candidates shown in the required level database, the work associated with the required physical condition level corresponding to the physical condition level of the first worker; It may be determined as the first work.

As a result, the work assigned to the first worker is narrowed down based on one of the physical condition level and the skill level, and the first work is determined based on the other, so that the first work can be determined appropriately. can be done.

Further, in the determination of the first work, if the specified physical condition level is lower than a predetermined level, work to take a break may be determined as the first work.

As a result, for example, when the first worker is in poor physical condition, the physical condition of the first worker can be recovered, and work efficiency can be improved.

In the acquisition of the biological information, the biological information indicating at least one of heart rate, body temperature, electroencephalogram, and blood pressure of the first worker may be acquired as a condition related to the biological body of the first worker. good.

Accordingly, the physical condition level of the first worker can be appropriately specified by using the biological information.

Further, a work management method according to an aspect of the present disclosure is a work management method in which a computer manages work in a facility equipped with a component mounting apparatus, wherein the physical condition levels of each of a plurality of workers are specified, and of the plurality of workers, and determine a worker having a physical condition level and a skill level required for a predetermined work as a worker to be assigned the predetermined work. .

As a result, a worker who has not only the physical condition level required for the predetermined work but also the skill level required for the predetermined work is determined as the worker for the predetermined work. as a result,
It is possible to suppress the possibility that a predetermined work requiring sufficient skill will be assigned to an unskilled worker. Therefore, it is possible to suppress the decrease in the production amount of the product produced by the work and to maintain the quality of the product. In other words, work efficiency can be further improved. The predetermined work may be the above-described work being executed by the first worker. In this case, the second worker is determined as the worker to whom the predetermined work is assigned.

In addition, the work management database d4 may indicate not only the work and time but also other information.

FIG. 5 is a flow chart showing an example of the processing operation of the work management device 100 according to the first embodiment.

First, the biometric measurement unit 203 of the terminal device 200a measures the biometric state of the first worker W1. Then, the terminal control unit 202 causes the biological information indicating the measured state and the identifier stored in the terminal storage unit 206 to be transmitted from the terminal communication unit 201 to the work management apparatus 100 via the communication network NW. . As a result, the management communication unit 101 of the work management device 100 receives the biometric information and the identifier from the terminal device 200a. Thereby, the management control unit 102 acquires the biometric information and the identifier of the first worker W1 (step S1). In other words, the management control unit 102 acquires the biological information indicating the biological state of the first worker W1 measured by the sensor of the terminal device 200a, and acquires the identifier for identifying the first worker W1. For example, the management control unit 102 acquires biometric information indicating at least one of the heart rate, body temperature, electroencephalogram, and blood pressure of the first worker W1 as the state of the biometrics of the first worker W1.

Next, the physical condition level identification unit 103 refers to the basic biometric database d1 of the basic biometric DB storage unit 107. FIG. Then, the physical condition level specifying unit 103 searches the basic biometric information of the first worker W1 from the basic biometric database d1. Specifically, the physical condition level specifying unit 103 determines the basic biometric information associated with the identifier acquired in step S1 among the plurality of basic biometric information contained in the basic biometric database d1 as the basic biometric information of the first worker W1. Search as biometric information. That is, the physical condition level specifying unit 103 acquires the basic biometric information associated with the identifier acquired in step S1 in the basic biometric database d1 as the basic biometric information of the first worker W1 (step S2).

Next, the physical condition level specifying unit 103 specifies the physical condition level of the first worker W1 by comparing the biometric information acquired in step S1 with the basic biometric information of the first worker W1 (step S3 ). For example, the physical condition level specifying unit 103 specifies “good” as the physical condition level if the numerical value of each condition indicated by the biometric information is within the allowable range of the numerical value of each condition indicated by the basic biometric information. Conversely, the physical condition level specifying unit 103 specifies "bad" as the physical condition level if the numerical value of any state indicated by the biological information is outside the allowable range of the numerical value of the state indicated by the basic biological information. .

Specifically, if the above states are body temperature and blood pressure, the physical condition level specifying unit 103 determines whether the body temperature indicated by the biological information is within the allowable range of body temperature indicated by the basic biological information. . The allowable range of the body temperature is, for example, a range from -0.5% to +0.5% of the body temperature indicated by the basic biological information. Furthermore, the physical condition level identifying unit 103 determines whether or not the blood pressure indicated by the biological information is within the allowable range of blood pressure indicated by the basic biological information. The allowable blood pressure range is, for example, -5% to +5% of the blood pressure indicated by the basic biological information. When the body temperature indicated by the biological information is within the allowable range and the blood pressure indicated by the biological information is within the allowable range, the physical condition level specifying unit 103 specifies "good" as the physical condition level. Conversely, if at least one of the body temperature and blood pressure indicated by the biological information is not within their allowable range, the physical condition level specifying unit 103 specifies "bad" as the physical condition level.

Next, the skill level identification unit 104 refers to the skill database d2 of the skill DB storage unit 108. FIG. Then, the skill level identifying unit 104 identifies the skill level of the first worker W1 by searching the skill level of the first worker W1 from the skill database d2. Specifically, the skill level identifying unit 104 sets the skill level associated with the identifier acquired in step S1 among the plurality of skill levels shown in the skill database d2 as the skill level of the first worker W1. Identify (step S4).

Next, the management control unit 102 refers to the work management database d4 of the work management DB storage unit 110 (step S5). Then, the management control unit 102 determines whether or not the work is associated with the identifier acquired in step S1 in the work management database d4 and the work is currently being performed. That is, the management control unit 102 determines whether or not the first worker W1 is working (step S6). Whether or not the work associated with the identifier is currently being performed is determined by whether or not the current time is between the start time and end time of the work indicated in the work management database d4. Further, as another determination means, it may be determined whether or not the work is currently being performed based on whether or not the input operation of the first worker W1 is received from the input unit 204 . The management control unit 102 determines that the work is currently being performed if the current time is between the start time and the end time. Note that when the end time is undecided, the management control unit 102 determines that the work is currently being performed if the current time is after the start time.

Here, when the management control unit 102 determines that the first worker W1 is not working (No in step S6), the management control unit 102 makes the work determination unit 105 determine the work of the first worker W1. That is, in the work management database d4, if no work is associated with the identifier of the first worker W1, or if work is associated with the identifier but the work is not currently being performed, The management control unit 102 causes the work decision unit 105 to decide the work. As a result, the work determination unit 105 refers to the demand level database d3 of the demand level DB storage unit 109. FIG. Then, the work determination unit 105 selects the work associated with the required physical condition level and the required skill level corresponding to the physical condition level and the skill level of the first worker W1 among the plurality of works shown in the required level database d3. Determined as the first task. That is, the work determination unit 105 determines, as the first work, the work associated with the required physical condition level and required skill level corresponding to the physical condition level and skill level specified in steps S3 and S4 in the required level database d3. (step S7). Note that the first work is not limited to specific work performed on the production floor, and includes work that is not related to specific work such as breaks. For example, if the physical condition level specified in step S3 is "poor" and the skill level specified in step S4 is "low", the work determination unit 105 determines "rest" as the first work. . As described above, in the present embodiment, when the specified physical condition level is lower than a predetermined level, the work determination unit 105 determines work to take a break as the first work.

The required physical condition level corresponding to the physical condition level can also be said to be the required physical condition level satisfied by the physical condition level. The required skill level corresponding to the skill level can also be said to be the required skill level satisfied by the skill level. Also, the required physical condition level corresponding to the physical condition level is a level equal to or lower than the physical condition level. For example, if the physical condition level is "good", the required physical condition level corresponding to that physical condition level is either "good" or "poor". If the physical condition level is "bad", the required physical condition level corresponding to the physical condition level is "bad". Similarly, the required skill level corresponding to the skill level is below the skill level. For example, if the skill level is "high", the required skill level corresponding to that skill level is "high", "medium" or "low". Also, if the skill level is "medium", the required skill level corresponding to that skill level is "medium" or "low". Also, if the skill level is "low", the required skill level corresponding to that skill level is "low".

Then, the information generation unit 106 generates instruction information instructing execution of the first work, and the management communication unit 101 transmits the instruction information to the terminal device 200a via the communication network NW. The terminal control unit 202 of the terminal device 200a displays the content of the instruction information on the display 205. FIG. As a result, the first worker W1 is notified of the first work (step S8). As described above, in the present embodiment, by displaying information indicating the determined first work on display 205, first worker W1 is prompted to perform the first work. Then, the work management device 100 ends the processing operation regarding the work management of the first worker W1.

On the other hand, when the management control unit 102 determines in step S6 that the first worker W1 is working (Yes in step S6), in the work management database d4, the identifier of the first worker W1 is associated with the current Identify the work being done as the work in progress. That is, the management control unit 102 identifies the work being performed by the first worker W1 as the work in progress. It should be noted that the ongoing work does not mean only the work actually being performed by the worker, but means the work that has already been assigned to the worker. Then, the management control unit 102 refers to the request level database d3 of the request level DB storage unit 109, and specifies the request level associated with the work in progress in the request level database d3 (step S9). That is, the required physical condition level and required skill level of the work in progress are specified.

Next, the management control unit 102 determines whether or not the level of the first worker W1 satisfies the required level of the work in progress (step S10). The level of the first worker W1 is the physical condition level and skill level specified in steps S3 and S4. That is, it is determined whether or not the physical condition level satisfies the required physical condition level of the work in progress and the skill level satisfies the required skill level of the work in progress.

Here, whether or not the physical condition level satisfies the required physical condition level of the work in progress is determined by whether or not the physical condition level is equal to or higher than the required physical condition level. For example, if the physical condition level is "good" and the required physical condition level is "good," it is determined that the physical condition level satisfies the required physical condition level. If the physical condition level is "bad" and the required physical condition level is "good", it is determined that the physical condition level does not satisfy the required physical condition level. Similarly, whether or not the skill level satisfies the required skill level of the work in progress is determined by whether or not the skill level is equal to or higher than the required skill level. For example, if the skill level is "high" or "medium" and the required physical condition level is "medium", it is determined that the skill level satisfies the required skill level. Also, if the skill level is "medium" and the required skill level is "high", it is determined that the skill level does not satisfy the required skill level.

Next, when it is determined that the level of the first worker W1 satisfies the required level of the work in progress (Yes in step S10), the work management device 100 performs processing operations related to work management of the first worker W1. exit. On the other hand, when it is determined that the level of the first worker W1 does not satisfy the required level of the work in progress (No in step S10), the management control unit 102 decides to change the work in progress (step S11). . That is, the management control unit 102 causes the work determination unit 105 to determine work other than the work being performed by the first worker W1. In this case, as in the process of step S7, the work determination unit 105 associates the required physical condition level and required skill level corresponding to the physical condition level and skill level specified in steps S3 and S4 in the required level database d3. The work to be performed is determined as the first work (step S12). For example, the work determination unit 105 determines, as the first work, a work whose required skill level is lower than that of the work being executed, among the plurality of works shown in the required level database d3. Specifically, when the skill level identified in step S4 is "medium" and the work being executed is "soldering" with a required skill level of "high", the work determining unit 105 determines that the required skill level is "medium". is determined as the first work. In the above example, the work requiring a lower skill level than the work being executed is determined as the first work. It may be determined as one work. For example, if the skill level specified in step S4 is "high" and the task being executed has the required skill level "low", the task determination unit 105 determines the task "part supply", Alternatively, the work "soldering" with the required skill level "high" may be determined as the first work. In this way, the first work is changed to match the skill level of the first worker W1.

Then, the information generation unit 106 generates instruction information for instructing the change to the first work. The management communication unit 101 transmits the instruction information to the terminal device 200a via the communication network NW. The terminal control unit 202 of the terminal device 200a displays the content of the instruction information on the display 205. FIG. Thereby, the change to the first work is notified to the first worker W1 (step S13). Then, the work management device 100 ends the processing operation regarding the work management of the first worker W1.

FIG. 6 is a sequence diagram showing an example of processing operations of the work management system 1000 according to the first embodiment. Specifically, FIG. 6 is a sequence diagram corresponding to the flow of steps S1 to S8 in FIG.

The terminal device 200a first acquires the biometric information of the first worker W1 (step S101), and transmits the biometric information and the identifier of the first worker W1 to the work management device 100 (step S102).

The work management device 100 receives the biometric information and the identifier of the first worker W1 from the terminal device 200a, and identifies the physical condition level of the first worker W1 based on the biometric information and the identifier (step S103). Next, the work management device 100 identifies the skill level of the first worker W1 based on the identifier (step S104). Then, the work management device 100 determines the first work corresponding to the physical condition level specified in step S103 and the skill level specified in step S104 (step S105). The work management device 100 generates instruction information instructing execution of the determined first work (step S106), and transmits the instruction information to the terminal device 200a (step S107).

The terminal device 200a receives the instruction information from the work management apparatus 100, and displays the content indicated by the instruction information on the display 205 (step S108).

[Effects, etc.]
As described above, in the present embodiment, work management device 100 identifies the physical condition level and skill level of first worker W1, and instructs first worker W1 to perform work according to the physical condition level and skill level. It is determined as the first task to be assigned. As a result, the first worker W1 is assigned work corresponding to not only the physical condition level but also the skill level of the first worker W1 as the first work. As a result, it is possible to reduce the possibility of assigning work that requires sufficient skill to a worker who does not have the skill. Therefore, it is possible to suppress the decrease in the production amount of the product produced by the work and to maintain the quality of the product. In other words, work efficiency can be further improved.

In addition, the work management device 100 obtains biological information indicating the state of the biological body of the first worker W1, and compares the biological information with the basic biological information of the first worker W1 to obtain the first worker W1 identify the fitness level of Thereby, the physical condition level of the first worker W1 can be appropriately specified based on the difference between the biological information and the basic biological information. In addition, work management device 100 acquires biological information indicating at least one of heart rate, body temperature, electroencephalogram, and blood pressure of first worker W1 as a condition related to the biological body of first worker W1. Thereby, the physical condition level of the first worker W1 can be appropriately specified by using the biological information.

The work management apparatus 100 also refers to the basic biometric database d1 and searches for the basic biometric information of the first worker W1 from the basic biometric database d1. Thereby, the basic biometric information of the first worker W1 can be properly grasped.

The work management device 100 also refers to the skill database d2 and searches the skill level of the first worker W1 from the skill database d2 to specify the skill level of the first worker W1. Thereby, the skill level of the first worker W1 can be appropriately specified.

In addition, the work management device 100 refers to the required level database d3, and among the plurality of works shown in the required level database d3, the required physical condition level and required skill corresponding to the physical condition level and skill level of the first worker W1. The work associated with the level is determined as the first work. Thereby, the first worker W1 can appropriately perform the first work. As a result, it is possible to improve the working efficiency of the first work.

In addition, the work management device 100 acquires the identifier of the first worker W1, and selects the basic biometric information associated with the identifier among the plurality of basic biometric information contained in the basic biometric database d1 as the first worker W1. Search as the basic biometric information of W1. As a result, since the basic biometric information of the first worker W1 is searched using the identifier of the first worker W1, erroneous searches can be suppressed.

Further, the work management device 100 acquires the identifier of the first worker W1, and sets the skill level associated with the identifier among the plurality of skill levels shown in the skill database d2 to the skill level of the first worker W1. Specify as a level. Thereby, since the skill level of the first worker W1 is specified using the identifier of the first worker W1, the skill level of the first worker W1 can be specified more appropriately.

In addition, the work management device 100 identifies the work being performed by the first worker W1, and determines, among the plurality of works, the work requiring a lower skill level than the work being performed as the first work. Thereby, when the skill level of the first worker W1 does not satisfy the skill level required for the work in progress, the work of the first worker W1 is changed from the work in progress to the first work. . That is, the work of the first worker W1 is changed to the first work that requires a skill level lower than that required for the work in progress. Therefore, the performance of the first worker W1 can be utilized, and the work efficiency of the facility F as a whole can be improved.

Further, the work management apparatus 100 transmits the instruction information indicating the determined first work, thereby causing the display 205 of the terminal device 200a to display the instruction information. Thereby, the work management device 100 prompts the first worker W1 to perform the first work. As a result, it is possible to cause the first worker W1 to appropriately perform the first work.

Further, when the specified physical condition level is a level corresponding to poor physical condition, the work management device 100 determines work to take a break as the first work. As a result, the physical condition of the first worker W1 can be recovered, and work efficiency can be improved.

Here, when determining the first work in steps S7 and S12 of FIG. You can narrow down. For example, the work determination unit 105 selects at least one work associated with the required physical condition level corresponding to the physical condition level of the first worker W1 among the plurality of works shown in the required level database d3 as the first work. Select as candidate. Then, the work determination unit 105 selects the work associated with the required skill level corresponding to the skill level of the first worker W1 among at least one first work candidate shown in the required level database d3 as the first work. Determined as

Alternatively, the work determining unit 105 selects at least one work associated with the required skill level corresponding to the skill level of the first worker W1 among the plurality of works shown in the required level database d3 as the first work. Select as candidate. Then, the work determination unit 105 selects the work associated with the required physical condition level corresponding to the physical condition level of the first worker W1 among at least one first work candidate shown in the required level database d3 as the first work. Determined as

As a result, the work assigned to the first worker W1 is narrowed down based on one of the physical condition level and the skill level, and the first work is determined based on the other, so the first work is determined appropriately. be able to.

(Embodiment 2)
The work management system 1000 in this embodiment allocates the work in progress to another worker when the work of the first worker W1 in the first embodiment is changed from the work in progress to the first work. In other words, the work management system 1000 in this embodiment changes the worker of the work in progress. It should be noted that among the constituent elements in the present embodiment, the constituent elements that are the same as in Embodiment 1 are assigned the same reference numerals as those in Embodiment 1, and detailed description thereof will be omitted.

FIG. 7 is a diagram showing an example of the work management system 1000 according to the second embodiment.

A work management system 1000 according to the present embodiment includes terminal devices 200a to 200h attached to workers W1 to W8, and a work management device 100. FIG.

The terminal devices 200b to 200h are wearable terminals having the same configuration as the terminal device 200a of the first worker W1, and are connected to the work management device 100 via the communication network NW. These terminal devices 200b to 200h measure the physical condition of the worker wearing the terminal device, and transmit biological information indicating the measured condition to the work management apparatus 100 via the communication network NW. do. Note that each of the terminal devices 200b to 200h may be referred to as the terminal device 200 hereinafter.

The work management device 100 acquires biological information from each of the terminal devices 200a to 200h via the communication network NW. The work management device 100 manages the work of the workers W1 to W8 using the biological information.

FIG. 8 is a flowchart showing an example of processing operations of the work management device 100 according to the second embodiment.

The work management apparatus 100 according to the second embodiment executes steps S1 to S13 shown by the flowchart of FIG. 5 according to the first embodiment, and further executes the process of step S40.

Specifically, first, the work management device 100 performs level identification processing for the first worker W1 (step S20). In the level specifying process of the first worker W1, the processes of steps S1 to S4 in FIG. 5 are performed. Thereby, the physical condition level and the skill level of the first worker W1 are specified as the level of the first worker W1. Furthermore, the work management device 100 executes the processes of steps S5 to S13 in FIG.

Then, in the present embodiment, after the process of step S13, the work management apparatus 100 performs a worker selection process for the work in progress (step S40). That is, after the processing of steps S12 and S13, the work of the first worker W1 is changed from the work in progress to the first work. As a result, there is no worker to perform the work in progress. Therefore, in step S40, a process for selecting a worker for the ongoing work is executed as the above-described worker selection process.

FIG. 9 is a flowchart showing an example of worker selection processing according to the second embodiment. That is, FIG. 9 is a flow chart showing in detail the process of step S40 of FIG.

First, the management control unit 102 of the work management device 100 selects one of the workers W2 to W8 as a candidate worker. Candidate workers may be selected at random, or may be selected in numerical order of worker identifiers. The candidate worker is a candidate for the second worker who will execute the work in progress of the first worker W1 instead of the first worker W1. For example, first, worker W2 is selected as a candidate worker. Then, the work management device 100 performs the same processes as the processes of steps S1 to S4 in FIG. 5 performed on the first worker W1 on the candidate worker. That is, the biomeasuring unit 203 of the terminal device 200 worn by the candidate worker measures the biometric state of the candidate worker. Then, the terminal control unit 202 of the terminal device 200 transfers the biological information indicating the measured state and the identifier stored in the terminal storage unit 206 of the terminal device 200 from the terminal communication unit 201 to the communication network NW. to the work management device 100 via. As a result, the management communication unit 101 of the work management device 100 receives the biometric information and identifier of the candidate worker from the terminal device 200 . Thereby, the management control unit 102 acquires the biometric information and the identifier of the candidate worker (step S41).

Next, the physical condition level identification unit 103 refers to the basic biometric database d1 of the basic biometric DB storage unit 107. FIG. Then, the physical condition level identification unit 103 searches the basic biometric information of the candidate worker from the basic biometric database d1. That is, the physical condition level specifying unit 103 acquires the basic biometric information associated with the identifier acquired in step S41 as the basic biometric information of the candidate worker in the basic biometric database d1 (step S42).

Next, the physical condition level specifying unit 103 specifies the physical condition level of the candidate worker by comparing the biometric information acquired in step S41 with the basic biometric information of the candidate worker (step S43).

Next, the skill level identification unit 104 refers to the skill database d2 of the skill DB storage unit 108. FIG. Then, the skill level identifying unit 104 identifies the skill level of the candidate worker by searching the skill level of the candidate worker from the skill database d2. That is, the skill level identification unit 104 identifies the skill level associated with the identifier acquired in step S41 as the skill level of the candidate worker in the skill database d2 (step S44).

Then, the management control unit 102 refers to the required level database d3 of the required level DB storage unit 109, and specifies the required level associated with the ongoing work of the first worker W1 in the required level database d3 ( step S45). That is, the required physical condition level and required skill level of the work in progress are specified.

Next, the management control unit 102 determines whether or not the candidate worker's level satisfies the required level of the work in progress (step S46). The level of the candidate worker is the physical condition level and skill level specified in steps S43 and S44. That is, it is determined whether or not the physical condition level of the candidate worker satisfies the required physical condition level of the work in progress and the skill level of the candidate worker satisfies the required skill level of the work in progress.

Here, if it is determined that the candidate worker's level satisfies the required level of the work in progress (Yes in step S46), the management control unit 102 determines the candidate worker as the second worker. The second worker is, as described above, a worker who performs the work being performed by the first worker W1 instead of the first worker W1. That is, in the process of step S12 in FIG. 8, when the first work different from the work in progress is determined, the management control unit 102 selects the workers of the work in progress from the first worker W1 to the second work. decision to replace a person. This second worker has the fitness level and skill level required for the work in progress. As a result, the information generation unit 106 generates instruction information for instructing a change to the work in progress. The management communication unit 101 transmits the instruction information to the terminal device 200 of the second worker via the communication network NW. As a result, the second worker is notified of the change to the work in progress (step S47). Then, the work management apparatus 100 ends the worker selection process for the work in progress.

On the other hand, if it is determined that the level of the candidate worker does not satisfy the required level of the work in progress (No in step S46), the management control unit 102 selects another worker as the candidate worker (step S48). ). For example, when worker W2 has been selected as a candidate worker, worker W3 is selected as a new candidate worker.

Thus, in this embodiment, the physical condition level identifying unit 103 identifies the physical condition level of each of at least one worker other than the first worker W1, and the skill level identifying unit 104 identifies the physical condition level of at least one worker. identify the skill level of each of the workers in the Then, the management control unit 102 associates each work with a required physical condition level, which is a physical condition level required for the work, and a required skill level, which is a skill level required for the work. The request level database d3 indicated by is referred to. Thereby, the management control unit 102 specifies the required physical condition level and the required skill level of the work in progress. Then, the management control unit 102 determines, among the at least one worker, a worker having a physical condition level and a skill level corresponding to the required physical condition level and the required skill level of the work in progress as a second worker. .

10 and 11 are sequence diagrams showing an example of processing operations of the work management system 1000 according to the second embodiment. Note that the sequence shown by FIG. 11 is a sequence that follows the sequence shown by FIG. 10 and 11 are sequence diagrams corresponding to the flow of steps S20, S5, S6, S9-S13 and S40 in FIG. 8 and the flow of steps S41-S47 in FIG.

The terminal device 200a and the work management device 100 first execute the processes of steps S101 to S108, as in the first embodiment. Specifically, the terminal device 200a acquires the biometric information of the first worker W1 (step S101), and transmits the biometric information and the identifier of the first worker W1 to the work management device 100 (step S102). ).

The work management device 100 receives the biometric information and the identifier of the first worker W1 from the terminal device 200a, and identifies the physical condition level of the first worker W1 based on the biometric information and the identifier (step S103). Next, the work management device 100 identifies the skill level of the first worker W1 based on the identifier (step S104). Then, the work management device 100 determines the first work corresponding to the physical condition level specified in step S103 and the skill level specified in step S104 (step S105). The work management device 100 generates instruction information instructing execution of the determined first work (step S106), and transmits the instruction information to the terminal device 200a (step S107). Here, in the examples of FIGS. 10 and 11, when the first work is determined, the first worker W1 is performing work other than the first work. Therefore, the instruction information is information for instructing a change from the work in progress, which is the work being performed by the first worker W1, to the first work. The terminal device 200a receives the instruction information from the work management apparatus 100, and displays the content indicated by the instruction information on the display 205 (step S108). After seeing this content, the first worker W1 interrupts the work in progress and executes the first work.

Next, the terminal device 200 of the candidate worker acquires the biometric information of the candidate worker (step S111), and transmits the biometric information and identifier of the candidate worker to the work management device 100 (step S112).

The work management device 100 receives the biometric information and the identifier of the candidate worker from the terminal device 200, and identifies the physical condition level of the candidate worker based on the biometric information and the identifier (step S113). Next, the work management device 100 identifies the skill level of the candidate worker based on the identifier (step S114). Here, the physical condition level identified in step S113 and the skill level identified in step S114 satisfy the physical condition level and skill level required for the ongoing work of the first worker W1. In this case, the work management apparatus 100 determines the candidate worker as the second worker and determines the allocation of the work in progress to the second worker (step S115). Then, the work management device 100 generates instruction information instructing execution of the ongoing work (step S116), and transmits the instruction information to the terminal device 200 of the second worker (step S117).

The terminal device 200 receives the instruction information from the work management apparatus 100, and displays the content indicated by the instruction information on the display 205 (step S118). The second worker who sees this content executes the ongoing work interrupted by the first worker W1 instead of the first worker W1.

[Effects, etc.]
As described above, in the present embodiment, the work management apparatus 100 specifies the work being executed by the first worker W1, and when the first work different from the work being executed is determined, the work being executed It is decided to replace the first worker W1 with the second worker as the worker for the work. The second worker has the fitness level and skill level required for the task being performed. As a result, even if the work of the first worker W1 is changed from the work in progress to the first work, the work in progress is not stopped and the physical condition level and skill level required for the work in progress are adjusted. can continue to be performed by a second operator who has Therefore, the working efficiency of the facility F as a whole can be improved.

In addition, in the present embodiment, work management device 100 identifies the physical condition level and skill level of each of at least one worker other than first worker W1. Further, the work management device 100 identifies the required physical condition level and required skill level of the work being performed by the first worker W1 by referring to the required level database d3. Then, the work management device 100 determines, among the at least one worker, a worker having a physical condition level and a skill level corresponding to the required physical condition level and required skill level of the work in progress as a second worker. . This makes it possible to appropriately determine the second worker who can perform the work being performed by the first worker W1 in place of the first worker W1. That is, for the second worker, the ongoing work of the first worker W1 is determined as a new work. In other words, the determination of the first work assigned to the first worker W1 described above is also performed for the second worker. In other words, the physical condition level of the first worker W1 is specified, the skill level of the first worker W1 is specified, and among a plurality of works, the work according to the physical condition level and skill level is selected by the first worker W1. The second worker is also determined as the first work to be assigned to the second worker.

(Modification of Embodiment 2)
Here, in the second embodiment, the second worker is determined based on the level of the candidate worker and the requested level of the work being performed by the first worker W1. The determination of the second worker may also be made based on the demand level of the work being performed.

FIG. 12 is a diagram for explaining the processing operation of the work management system 1000 in the modified example of the second embodiment.

For example, among the workers W2 to W8 in the facility F, the level of the worker W2 and the level of the worker W8 satisfy the required level of the ongoing work of the first worker W1. In this case, in Embodiment 2 above, both worker W2 and worker W8 can be determined to be the second worker. Here, worker W2 and worker W8 are also performing their respective tasks, and the required levels of those tasks (that is, the tasks being performed) are different from each other. Therefore, the work management apparatus 100 assigns a worker who is performing work at a lower required level than the work in progress of the first worker W1 among the worker W2 and the worker W8 as a second worker. may decide. For example, the required level of the work being performed by worker W2 is equal to or higher than the required level of the work being performed by first worker W1, and the required level of the work being performed by worker W8 is Lower than required level of work. In this case, the worker W8 is determined as the second worker instead of the worker W2.

The work management apparatus 100 in this modified example executes the process according to the flowchart shown in FIG. 8 of the second embodiment. However, the work management apparatus 100 in this modified example executes a process different in content from the process of step S40 (that is, the worker selection process) shown in FIG. 9 of the second embodiment.

FIG. 13 is a flowchart illustrating an example of worker selection processing according to the modification of the second embodiment. 13, steps S51 and S52 are added to the flowchart shown in FIG.

In step S45 in this modified example, the requested level of the work being executed by the first worker is specified as the first requested level. Then, in step S46, when the management control unit 102 determines that the level of the candidate worker satisfies the required level of the work in progress of the first worker W1 (Yes in step S46), the management control unit 102 stores the work management database d4. refer. The management control unit 102 identifies, in the work management database d4, the work that is associated with the identifier acquired in step S41 and that is currently being performed as the work in progress of the candidate worker. Further, the management control unit 102 refers to the required level database d3, and specifies the required level associated with the ongoing work of the candidate worker in the required level database d3 as the second required level (step S51).

Next, the management control unit 102 determines whether or not the second required level is lower than the first required level of the work being performed by the first worker W1 (step S52). Here, when the management control unit 102 determines that the second required level is not lower than the first required level (No in step S52), the process of step S48 is executed. On the other hand, when the management control unit 102 determines that the second required level is lower than the first required level (Yes in step S52), it executes the process of step S47.

Whether or not the second required level is lower than the first required level of the ongoing work of the first worker W1 is determined by determining whether or not the required skill level of the second required levels is equal to the level of the required skill level of the ongoing work of the first worker W1. It may be determined by whether or not the skill level is lower than the required skill level. In other words, the management control unit 102 refers to the work management database d4 indicating the work performed by each of the plurality of workers W1 to W8, so that at least one worker other than the first worker W1 Identify the work each worker is performing. Then, the management control unit 102 designates, among the at least one worker, a worker who is performing work requiring a lower skill level than the work being performed by the first worker W1 as a second worker. Determined as

Accordingly, the skill level required for the work being performed by the second worker is lower than the skill level required for the work being performed by the first worker W1. Therefore, even if the worker of the work in progress is changed from the first worker W1 to the second worker, the work that the second worker was executing can be easily assigned to another worker. Therefore, the working efficiency of the facility F as a whole can be improved.

Further, whether or not the second required level is lower than the first required level of the work being performed by the first worker W1 depends on whether the required physical condition level of the second required levels is the work being performed by the first worker W1. It may be determined by whether or not the physical condition level is lower than the required physical condition level for the work. In this case, the physical condition level required for the work being performed by the second worker is lower than the physical condition level required for the work being performed by the first worker W1. Therefore, in the same manner as described above, even if the worker for the work in progress is changed from the first worker W1 to the second worker, the work being executed by the second worker can be easily assigned to another worker. be able to. Therefore, the working efficiency of the facility F as a whole can be improved.

(Supplementary work)
The work in Embodiments 1 and 2 and their modifications may be each work shown in the demand level database d3 of FIG. may The work of the worker will be supplemented below.

For example, the operator performs splicing work, parts supply work to the autoload feeder, feeder placement work, soldering work, empty tape box cleaning work, recognition error handling work, adsorption error handling work, and transport error handling. Work such as work is performed on the production floor.

The splicing work is a work for splicing a tape on a new reel to a tape on an old reel, which has been supplied with stored components and which has little left, and continuing to supply components from the old reel using the new reel. Specifically, the operator cuts off the leading end of the tape on the new reel and the trailing end of the tape on the old reel with scissors. Then, the worker brings the tape tip of the new reel and the trailing edge of the tape of the old reel into contact with each other at the above-mentioned break, and affixes the affixing tape to join them together.

The work of supplying components to the auto load feeder is the work of supplying reel tape to the auto load feeder attached to the production apparatus. Specifically, the operator cuts the leading end of the tape on the reel up to the portion where the components are stored. Next, the operator operates a switch for opening the shutter of the tape insertion port of the autoload feeder to open the shutter, and inserts the tape of the reel with the tip cut off into the tape insertion port. Then, when the setting of the tape is completed, the operator operates a switch for starting automatic feeding to start automatic feeding.

The feeder placement work is the work of attaching the tape feeder to the production device. Specifically, the worker attaches the tape feeder to a cart attached to the production apparatus. Then, the worker attaches the reel to the cart on which the tape feeder is attached.

The solder leveling work is a work of stirring solder used in a screen printing device or the like. Since solder is stored in a refrigerator or the like and becomes hard, it is necessary to stir the solder taken out of the refrigerator or the like before use. The operator stirs the solder for about 5-10 minutes, depending on the type of solder, to achieve good softness.

Empty tape box cleaning work is work for cleaning an empty tape box that is attached to a cart that is attached to a production apparatus and stores empty tape that has been emptied after components have been supplied. Specifically, the worker removes the empty tape box in which the empty tape is accumulated from the cart and discards the empty tape to clean the empty tape box. Then, the worker attaches the cleaned empty tape box to the cart.

Recognition error handling work is work performed when a recognition error occurs in a camera provided in a production apparatus. For example, a recognition error occurs when a part photographed by a camera is not in the correct position or orientation in the recognition image, or when the cover glass of the camera is dirty. In such a case, the operator should adjust the position, tilt or setting of the camera, adjust the position or tilt of the nozzle that holds the part, remove dirt from the nozzle, or cover the camera as work to deal with the recognition error. Wipe off the dirt on the glass. In addition, for example, if the setting of the board recognition mark preset in the production equipment is incorrect, or if the board stop position is misaligned, a recognition error (specifically, the recognition mark of the board error) occurs. In such a case, the operator corrects the setting of the recognition mark or adjusts the position of the substrate as work to deal with the recognition error.

The suction error handling work is work to be performed when a nozzle suction error occurs. For example, when a pick-up error occurs, the operator checks whether the setting of the component pick-up position of the nozzle is correct as work to deal with the pick-up error, and corrects the setting if it is not correct. Further, for example, when a suction error occurs, the operator adjusts the setting of the suction speed to an appropriate speed as a work to deal with the suction error.

The board transfer error handling work is a work performed when a board transfer error occurs. For example, a substrate transport error occurs when the belt transporting the substrate or the guide of the transported substrate is dirty. In such a case, the operator cleans the belt or guide as work to deal with the board transfer error. Further, for example, when the board detection sensor of the conveyor is in the detection state even though the board is not detected, a board transfer error occurs. In such a case, the operator checks whether the board detection sensor is dirty as work to deal with the board transfer error, and wipes off the dirt if it is.
