Description

  The present invention relates to a work management system and a work management method for managing information related to work divided into a plurality of work processes.

  Conventionally, many mass production methods for mass production at one time have been adopted for product production. The mass production method is effective in reducing the cost per unit product. However, the mass production system has a large inventory when the number of products sold is less than planned, and various problems that occur in multiple work processes (the work time of each work process). There was a problem that it was not possible to find or eliminate a reduction in work efficiency due to variations.

  Therefore, in recent years, a so-called JIT (Just In Time) production method has been widely adopted in which a necessary product is provided to a necessary place in a necessary amount when necessary. According to the JIT production method, there is no problem of having a large stock. However, the JIT production method is originally less efficient than the mass production method. Therefore, in order to improve the production efficiency in the JIT production method, it is necessary to improve the work efficiency while omitting various troubles and maintaining the certainty of the work.

For example, in Patent Document 1, an ID tag for identifying a worker and an ID tag for identifying a work object that identifies a work object are read by an ID tag reader, and the read information and a work area are defined as follows. A technique for managing work time by transmitting information to be specified and operation information of equipment in the work area to a performance management CPU is disclosed.
JP 2005-182656 A

However, with the technique disclosed in Patent Document 1, information regarding work (work time information and the like) can be collected, but each worker confirms his work (hereinafter referred to as work confirmation) firmly. There is a problem that the certainty of work cannot always be maintained.
Also, if you want to keep a record of the work confirmation, the worker fills in the work check sheet on paper media with a writing instrument, or operates the contents displayed on the computer screen with a keyboard, mouse or touch panel However, all of these methods have a problem that a heavy burden is placed on the worker, which causes a reduction in the efficiency of work to be performed.

  Accordingly, the present invention has been made to solve the above-described problem, and in a work management system that manages information related to a plurality of work processes, a work confirmation record is left without placing a heavy burden on the worker. With the goal.

In order to achieve the above object, according to the present invention, a predetermined work on a work object is divided into a plurality of work processes, and the plurality of work processes are performed in separate work spaces, and each work process includes one or more work processes. It is a work management system that has work procedures and manages information related to work in each work space using an IC tag in which information for specifying the contents of a predetermined work is written.
The work management system is attached to an information processing apparatus having a processing unit and a storage unit, and an IC tag place where an operator in the work space places an IC tag during work, and reads information on the IC tag placed in the IC tag place The IC tag information reading device that transmits the read information to the information processing device, and the voice input device that inputs the voice uttered by the worker and transmits the voice to the information processing device.
Then, when the processing unit of the information processing device receives the voice from the worker from the voice input device, the processing unit associates the voice with the work procedure based on the information of the IC tag received from the IC tag information reading device and stores the voice in the storage unit. Remember.

  According to the present invention, in a work management system that manages information relating to a plurality of work processes, it is possible to leave a record of work confirmation without placing a heavy burden on the worker.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is an overall configuration diagram of a work management system according to the first embodiment. The work management system S includes a management server 1 (information processing device), a work table 20 (201, 202), a display device 21 (211, 212) (notification device), a work management box 30 (301, 302) (IC tag storage). ) And reader / writer 4 (41, 42) (IC tag information reader). Each display device 21 and reader / writer 4 are connected to the management server 1 via a LAN (Local Area Network) 6 which is a communication network in the work management system S. Note that these connections may be made using wireless or power line carrier communication, etc., as long as communication is possible, without using a LAN.

In the present embodiment, description will be made assuming that the work WK (WK01, WK02), which is a work object, is worked in the work process W02 after the work process W01.
The work related to the workpiece WK is, for example, a work for assembling a semiconductor component to the circuit board, but may be other work. In addition, the work WK and the instruction A (A01, A02) are associated with the work WK01 and the instruction A01, and the work WK02 and the instruction A02 as a pair, respectively. The worker M (M01, M02) carries the work WK and the instruction A for each pair.

  Here, the instruction A is a document in which the order of work steps related to the paired work WK is described. Further, in the instruction A, an IC (Integrated Circuit) tag 5 (51, 52) in which information for specifying work to be performed on the pair of works WK is stored. The instruction A is put into the work management box 30 by the worker M immediately before the work is performed, and is taken out from the work management box 30 immediately after the worker M finishes the work.

The IC tag 5 embedded in the instruction A can be realized by, for example, a non-contact wireless ID (IDentification) tag such as RFID (Radio Frequency IDentification). As described above, the IC tag 5 stores information for specifying the work content of the work WK. Specifically, the IC tag 5 is used for the instruction number, the model number and product name of the work WK to be processed, the number of production personnel, and the work. The type of part, the order in which parts are attached, and the like are stored.
In this embodiment, the IC tag 5 embedded in the instruction A is of a type that does not have a battery and that obtains power from received radio waves. The IC tag 5 is preferable in terms of size reduction and cost reduction as long as it is a battery-free type, but may be a battery-mounted type.

Next, an apparatus provided in each work process will be described with reference to FIG. 2 (see FIG. 1 as appropriate). FIG. 2 is a configuration diagram showing an apparatus provided in each work process.
Each work process W is provided with a work table 20, and the worker M stands in front of the work table 20 and performs work related to the work WK.

A display device 21, a component box 22 and a switch 23 are placed on the work table 20.
The display device 21 displays information related to the work of the workpiece WK (details will be described later with reference to FIG. 3). The screen of the display device 21 is switched when the connected switch 23 is pressed by the worker M, and the display device 21 is connected to the management server 1 via the LAN 6.
The parts box 22 is a box that contains parts P necessary for work of the workpiece WK.

On the right side of the work table 20, a self-supporting work management box 30 is provided. The work management box 30 is a box into which an instruction A is input by a worker M who starts work. The work management box 30 is provided with (attached to) the reader / writer 4.
The reader / writer 4 reads information written in the IC tag 5 of the instruction A input into the work management box 30 and transmits the information to the management server 1 via the LAN 6.

  The work management box 30 is provided with a speaker 32 (notification device). The speaker 32 is connected to the management server 1 via the reader / writer 4 and the LAN 6. The speaker 32 is for notifying the worker M that work confirmation (quality confirmation) by voice is insufficient. The speaker 32 generates a buzzer sound, a voice message, or the like according to an instruction from the management server 1.

The reader / writer 4 is provided with an antenna 43 for catching radio waves from the headset microphone 24 (voice input device) worn by the worker M.
The worker M performs work by wearing the headset microphone 24 for voice input. The headset microphone 24 is, for example, a battery built-in type, and converts the voice emitted by the worker M into a radio wave and transmits it to the antenna 43 of the reader / writer 4.

Next, operations of the IC tag 5 and the reader / writer 4 when the instruction A is placed in the work management box 30 will be described.
A radio wave including a control signal is constantly transmitted from an antenna (not shown; separate from the antenna 43) of the reader / writer 4. When the instruction A is put in the work management box 30 adjacent to the reader / writer 4, an antenna (not shown) in the IC tag 5 embedded in the instruction A receives the radio wave from the reader / writer 4, and the antenna An electromotive force is generated by a resonance action.

Then, the IC tag 5 activates an internal circuit with the generated power, performs necessary processing, and transmits the processing result to the reader / writer 4 by radio waves from the antenna. The reader / writer 4 can acquire the information stored in the IC tag 5 by receiving the radio wave.
Note that the timing of reading the information of the IC tag 5 by the reader / writer 4 may not be always, but may be every predetermined time (for example, 10 seconds).
In this embodiment, only the case where a single instruction A is input to the work management box 30 will be described. However, a plurality of instructions A may be input to the work management box 30. In that case, each device may be set so that the reader / writer 4 can read the information of the IC tags 5 of a plurality of instructions A at a time.
The reader / writer 4 transmits information read from the IC tag 5 to the management server 1 via the LAN 6.

  Returning to FIG. 1, the management server 1 is an apparatus that performs information processing and the like, and is realized by, for example, a computer. The management server 1 includes a processing unit 11, an input unit 12, an output unit 13, and a storage unit 14. Although not particularly shown, the management server 1 also includes a communication interface.

The processing unit 11 stores information received from the reader / writer 4 in the storage unit 14 or performs calculations based on the information stored in the storage unit 14. For example, the processing unit 11 uses a CPU (Central Processing Unit). Realized.
Further, the processing unit 11 instructs the display device 21 to display the work content of the work WK, and instructs the speaker 32 to generate a buzzer sound or a voice message via the LAN 6.

The input unit 12 is a means for a user (such as an administrator) of the management server 1 to input information, and is a keyboard or a mouse, for example.
The output unit 13 is means for the processing unit 11 to inform the user of information, and is, for example, a display or a speaker.

  The storage unit 14 is a means for storing an execution program (not shown) of the processing unit 11, a work management table 15, audio data 16, and the like, and is realized by a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk, and the like. Is done. The work management table 15 is a table for managing information related to work in each work process W (details will be described later in FIG. 4). The audio data 16 is an area for storing data related to audio when the worker M confirms the work obtained via the headset microphone 24, the antenna 43, the reader / writer 4, and the LAN 6.

  Note that the sound at the time of the work confirmation by the worker M is a sound of a name uttered when confirming the work while pointing, for example, “Attachment of parts 1!” Or “Soldering!” It is. In addition, when there are a plurality of work procedures that are work units to be confirmed in one work process, the timing when the worker M confirms the work while producing a sound may be at the end of each work procedure. Alternatively, it may be performed collectively after the last work procedure is completed, or at another timing.

  The processing unit 11 of the management server 1 determines whether or not the voice data received from the headset microphone 24 via the antenna 43, the reader / writer 4 and the LAN 6 is a voice when the worker M confirms the work, with a predetermined threshold. Judgment is made using a condition that the value is greater than or equal to the value, voice recognition technology, or the like. Speech recognition can be realized by using a general speech recognition technique such as an acoustic model such as a hidden Markov model or a language model such as N-gram. If the work confirmation phrase is standardized (patterned), the accuracy of voice recognition can be improved. That is, the storage unit 14 stores standard data of voice for work confirmation corresponding to each work procedure, the processing unit 11 analyzes the received voice data from the headset microphone 24, and the analyzed voice is What is necessary is just to judge that the work confirmation corresponding to the work procedure was performed when it matched with the fixed form data. Alternatively, control may be performed such that recording is stopped when a voice “~ YOSHI!” Is detected, and recording is started when a voice of a threshold value or more comes next.

Next, an example of a screen displayed on the display device during work by the worker will be described with reference to FIG. 3 (see FIGS. 1 and 2 as appropriate). FIG. 3 is an explanatory diagram illustrating a display screen example of the display device.
The display device 21 is provided with an instruction number column 2101 to a warning display 2116. The display information in the instruction numbers 2101 to 2116 can be obtained from the information stored in the IC tag 5 of the instruction A put in the work management box 30.

  In the order number field 2101, information (such as A 01) specifying the work content of the work WK paired with the order A input to the work management box 30 is displayed. The work process column 2102 displays information (such as W01) for specifying a work process performed on the work table 20 (work space).

As the instruction content field 2103, a model number field 2104, an item name field 2105, and a number field 2106 are provided.
In the model number column 2104, the item name column 2105, and the number column 2106, information specifying these items is displayed regarding the work WK that is the work target.

In the work start time column 2107, the time when the instruction A is input to the work management box 30 is displayed. In the work end time column 2108, the time when the instruction A is taken out from the work management box 30 is displayed.
In the worker ID column 2109, information (such as M01) for identifying the worker M is displayed. The information specifying the worker M may be registered in the storage unit 14 of the management server 1 in advance, or the worker M provides an IC tag (not shown) for specifying the worker M. The management server 1 may recognize it by putting it in the work management box 30 and display it in the worker ID column 2109.
The completed number column 2110 displays the completed number among the number of production members (eight in this case) displayed in the number column 2106.

As the assembly instruction information column 2111, a procedure (work procedure) column 2112 and a work content column 2113 are provided.
The procedure column 2112 displays information for specifying a work procedure obtained by further subdividing the work content to be performed in the work process. In the work content column 2113, the work content corresponding to each of the procedure columns 2112 is displayed.
The detailed work end time column 2114 displays the end time of each work procedure. For example, the time when the switch 23 is pressed by the worker M at the end of each work procedure is displayed.

In the voice work confirmation determination field 2115, whether or not the work confirmation by the voice of the worker M is performed for each work procedure is displayed as either “◯ (completed)” or “× (unfinished)”.
In the warning display field 2116, when the IC tag 5 is taken out from the work management box 30 by the worker M when at least one “× (incomplete)” is displayed in the voice work confirmation determination field 2115. A warning that the work confirmation by voice is incomplete is displayed by a lamp, character information, or the like.
In this way, the information related to the work content and the like is displayed in detail on the display device 21, so that the worker M can see the information and proceed with the work reliably.

  Next, the work management table will be described with reference to FIG. 4 (see FIGS. 1 to 3 as appropriate). FIG. 4 is an explanatory diagram showing the configuration of the work management table. The work management table 15 is provided for each instruction A. Here, the work management table 15 related to the instruction A01 is shown.

  As shown in FIG. 4, the work management table 15 includes a work process column 151, a work start time column 152, a work end time column 153, a procedure (work procedure) column 154, a voice work confirmation determination column 155, and a worker ID column 156. 6 columns.

The work process column 151 stores an identifier for identifying each work process W.
The work start time field 152 stores the time at which the instruction A is input to the work management box 30 of the work process (the work process specified in the work process field 151). The work end time column 153 stores the time when the instruction A is taken out from the work management box 30 of the work process.

The procedure column 154 stores information for specifying a work procedure obtained by further subdividing the work content of the work process, and this information corresponds to the information displayed in the procedure column 2112 (see FIG. 3) of the display device 21. Yes.
In the voice work confirmation determination column 155, for each procedure in the procedure column 154, whether or not the work confirmation by the voice of the worker M has been performed (whether or not completed) is “O (completed)” “× ( Incomplete) ”.

  The worker ID column 156 stores an identifier for identifying the worker M who is working in the work process. For example, an operator identification IC tag (not shown) is placed in or over the work management box 30 by the worker M, and the information in the worker identification IC tag is transferred to the reader / writer 4. By being read and transmitted to the management server 1 via the LAN 6, it may be reflected in the worker ID column 156 of the work management table 15.

Next, the operation in the work management system will be described with reference to FIG. 5 (see FIGS. 1 to 4 as appropriate). FIG. 5 is a flowchart showing the processing of the management server in the first embodiment.
First, the processing unit 11 of the management server 1 receives an instruction A in any work management box 30 depending on whether information (communication information) of the IC tag 5 is received from any reader / writer 4 via the LAN 6. It is determined whether or not it has been inserted (step S10).

When the instruction A is not input to any work management box 30 (No in step S10), the processing unit 11 returns to the process of step S10.
When the instruction A is input to any of the work management boxes 30 (Yes in Step S10), the processing unit 11 specifies the instruction number from the information of the IC tag 5 received from the reader / writer 4 via the LAN 6 (Step S10). S20), the work management table 15 corresponding to the instruction number is read from the storage unit 14.

  Subsequently, the processing unit 11 authorizes the work start time (step S30). In other words, the processing unit 11 writes the current time in the work start time column 152 in the row of the corresponding work step W in the work step column 151 in the work management table 15, and the worker in the worker ID column 156. Write information that identifies

Subsequently, the processing unit 11 determines whether or not the instruction A is taken out from the work management box 30 based on the communication information (communication end information or the like) received from the reader / writer 4 (step S40).
When the instruction A has not been taken out from the work management box 30 (No in step S40), the processing unit 11 determines whether or not there is a work confirmation by voice in any work procedure (step S50).

When there is a work confirmation by voice (Yes in step S50), the processing unit 11 rewrites the corresponding part of the voice work confirmation determination column 155 in the work management table 15 from “×” to “◯” (step S60), or The voice data at that time is stored in the voice data 16 of the storage unit 14, and the process returns to step S40.
If there is no work confirmation by voice (No in step S50), the processing unit 11 returns to step S40.

  When the instruction A is taken out from the work management box 30 (Yes in step S40), the processing unit 11 authorizes the work end time (step S70). That is, the processing unit 11 writes the current time in the work end time column 153 in the row of the corresponding work process W in the work process column 151 in the work management table 15.

  In this way, according to the work management system S of the first embodiment, in the work management system S that manages information related to a plurality of work processes, a work confirmation record is left without placing a heavy burden on the worker M. be able to. In other words, it is possible to realize high quality confirmation traceability by determining whether or not there is work confirmation by voice for each work procedure by the worker M, and recording the judgment result and the voice data at that time.

(Second Embodiment)
Next, a work management system according to the second embodiment will be described with reference to FIGS. 6 and 7. FIG. 6 is a flowchart showing processing of the management server in the second embodiment. FIG. 7 is an explanatory diagram of a warning display example by the display device. The configuration of the work management system S is the same as that of the first embodiment shown in FIGS. In FIG. 6, the same step codes (S10 and the like) are assigned to the same processes as those in FIG. That is, the process of FIG. 6 is obtained by adding the processes of step S21, step S22, step S61, and step S62 to the process of FIG. Furthermore, in FIG. 7, the same code | symbol is provided about the same structure as the structure in FIG.

  As shown in FIG. 6 (see FIGS. 1 to 4 as appropriate), first, the processing unit 11 of the management server 1 receives information (communication information) of the IC tag 5 from any reader / writer 4 via the LAN 6. It is determined whether or not the instruction A is input to any of the work management boxes 30 (step S10).

  When the instruction A is not input to any work management box 30 (No in step S10), the processing unit 11 returns to the process of step S10.

  When the instruction A is input to any of the work management boxes 30 (Yes in Step S10), the processing unit 11 specifies the instruction number from the information of the IC tag 5 of the instruction A received from the reader / writer 4 (Step S10). S20), the work management table 15 corresponding to the instruction number is read.

Subsequently, the processing unit 11 determines whether or not all the voice work confirmation determinations in the work process immediately preceding the work process are “◯” (step S21).
When all the voice work confirmation determinations in the previous work process are not “◯” (No in Step S21), the processing unit 11 instructs the display 21 of the work process to display work start prohibition (Step S21). S22). Upon receiving the instruction, for example, as shown in FIG. 7, the display device 21 has a character “Please return the instruction and the work to the previous work process because the work confirmation by voice is insufficient in the previous work process!”. Displayed in a warning display field 2117.
In this way, the worker M sees this display, knows that the work confirmation in the previous work process was insufficient, and returns the instruction and the work to the previous work process, thereby performing the work in the previous work process. It is possible to avoid a situation where the work is performed with insufficient confirmation.

In step S22, a sound to that effect may be output from the speaker 32 of the work management box 30 at the same time.
In the second embodiment, even when the instruction A is entered in the work management box 30 (Yes in Step S10), all the voice work confirmation determinations in the previous work process are not “◯” (Step S21). No) does not store the current time in the work start time field 152 (see FIG. 4).

  Returning to FIG. 6, when all the voice work confirmation determinations in the previous work process are “◯” (Yes in Step S <b> 21), the processing unit 11 recognizes the work start time (Step S <b> 30). In other words, the processing unit 11 writes the current time in the work start time column 152 in the row of the corresponding work step W in the work step column 151 in the work management table 15, and the worker in the worker ID column 156. Write information that identifies

Next, the processing unit 11 determines whether or not the instruction A is taken out from the work management box 30 based on the communication information (communication end information or the like) received from the reader / writer 4 (step S40).
When the instruction A has not been taken out from the work management box 30 (No in step S40), the processing unit 11 determines whether or not there is a work confirmation by voice in any work procedure (step S50).

When there is a work confirmation by voice (Yes in step S50), the processing unit 11 rewrites the corresponding part of the voice work confirmation determination column 155 in the work management table 15 from “×” to “◯” (step S60), or The voice data at that time is stored in the voice data 16 of the storage unit 14, and the process returns to step S40.
If there is no work confirmation by voice (No in step S50), the processing unit 11 returns to step S40.

When the instruction A is taken out from the work management box 30 (Yes in step S40), the processing unit 11 determines whether all the voice work confirmation determinations in the work process are “◯” (step S61).
When all the voice work confirmation determinations are not “◯” (No in Step S61), the processing unit 11 instructs the display device 21 to display that the voice work confirmation determination is insufficient (Step S62). . Upon receiving this instruction, the display device 21 displays, in a warning display field 2116 (see FIG. 3), the fact that the work confirmation by voice has not been completed by a lamp or character information. Thereby, the worker M can see that this display indicates that his / her work confirmation has been insufficient, and can follow up appropriately thereafter.

In step S62, a sound to that effect may be output from the speaker 32 of the work management box 30 at the same time.
In the second embodiment, even when the instruction A is taken out from the work management box 30 (Yes in step S40), if all the voice work confirmation determinations are not “◯” (No in step S61), The time at that time is not stored in the work end time column 153 (see FIG. 4).

  When all the voice work confirmation determinations are “◯” (Yes in step S61), the processing unit 11 authorizes the work end time (step S70). That is, the processing unit 11 writes the current time in the work end time column 153 in the row of the corresponding work process W in the work process column 151 in the work management table 15.

  In this way, according to the work management system S of the second embodiment, the work management system S that manages information related to a plurality of work processes can not only keep a record of work confirmation, but also can confirm work by voice. If it is insufficient, the worker M in the work process or the worker M in the next work process can be informed, and each worker M can take a more appropriate action thereafter.

Although description of each embodiment is completed above, the aspect of the present invention is not limited to these.
For example, the work management box and the reader / writer attached to the work management box may not be provided for all work tables, but may be provided for some work tables.
Further, the display device and the switch provided on each work table are not essential components and can be omitted as appropriate.
Furthermore, the work management box may not be a self-supporting type, but may be of another type such as a workbench attached type or a wall-hanging type.

In addition, although a headset microphone has been described as an example of a voice input device, a means for inputting voice uttered by a worker, such as a pin microphone attached to a worker's jacket or a microphone attached to a workbench or work management box As long as it is different.
Furthermore, although the voice data at the time of the work confirmation is assumed to be saved by the management server, the judgment result of the voice work confirmation (“◯” “×”) is assumed to be saved by the IC tag in the instruction even if it is not the management server. Also good.

In addition, although the voice spontaneously uttered by the worker is stored as the voice at the time of the work confirmation, a message for prompting the work confirmation is sent from the speaker of the work management box, etc. A confirmation sound may be emitted, and the sound may be stored as a record by the management server.
Furthermore, when the work confirmation by voice is insufficient, not only the display device of the work table but also the management server or the like may display that fact to the user (administrator).
In addition, specific configurations such as hardware and flowcharts can be appropriately changed without departing from the spirit of the present invention.
