Description

  The present invention relates to a production management system.

  In order to manage the production process, it is important that an operator records the work results of each work process in which each work process is sequentially performed. For this reason, for example, every time the worker finishes each work process, the work result is input to the computer.

In addition, there is a work instruction book display system that displays an image (work procedure image) that is a work instruction book that represents information necessary for work such as work procedures and procedures (see, for example, Patent Document 1). An operator can perform an accurate and efficient work by referring to the work instruction book.

  Like a conventional production management system, when a worker finishes each work process, the method in which the worker inputs the work result to the computer is likely to forget to input, and the production process is reliably managed. Is difficult.

Therefore, the present inventor ensures that the worker who performs the work while looking at the work procedure image reliably manages the production process while improving the work supportability by linking the display of the work procedure image and the production management. With the goal.

The present invention is a system for displaying a work procedure image for performing work while watching an operator, and for managing a production process composed of a plurality of work processes. When each work process is completed, the work process is Corresponding to each work procedure, explaining how to work for a plurality of work procedures that subdivide each work process, a work process management unit that performs work process management processing that stores the completion in the storage unit, a display unit, and a display unit A work procedure image display unit for displaying a work procedure image on the display unit, a completion input unit for receiving a completion input for completing display of the displayed work procedure image, and a control unit for performing control based on the completion input; When the control unit receives a completion input for displaying the work procedure image other than the final work procedure image in the work process, the work procedure image to be displayed next in the work process. Causes displayed by the work procedure image display unit, when receiving an indication of completion input of the final work procedure image in the working process, the display of the working process management screen for accepting an input of a work result of the terminated the working process The work process management unit receives an input of the work result, determines the obtained work result according to a predetermined determination criterion, generates a determination result, and determines the determination result and the work process. It is characterized in that the storage unit stores the completion of the process.

According to the present invention, when an operator sequentially inputs completion of display of a work procedure image in accordance with the progress of work in a certain work process and completes input of completion of the final work procedure image, the system is terminated. Since the work process management screen for accepting the input of the work results of the work process is displayed on the display unit, the worker who performs the work while looking at the work procedure image while managing the work procedure is reliably managed while improving work supportability. be able to. Further, the operator does not need to separately input the work procedure image and input the work process process, and the burden of the operator's input work is reduced.

The work process management unit, the display unit, the work procedure image display unit, the completion input unit, and the control unit are provided in a terminal device used by an operator, and display of the final work procedure image in the work process is completed. When input is made, it is preferable that the work process management unit determines whether the work result in the work process is good or not based on the work result acquired from the outside of the terminal device . In this case, whether or not the work result is acceptable can be determined when the completion input of the display of the final work procedure image is made.

  The number of work procedure images displayed for explanation of work in one work process is preferably a non-constant number in each work process. In this case, compared to the case where a fixed number of images are used per work process, the work procedure image is displayed more flexibly, and even if the work procedure images in one work process are increased, work supportability can be improved. The number of work processes to be managed is not increased, and production process management is easy.

  It is preferable that the work procedure image display unit is configured to be able to arbitrarily switch an image to be displayed among a plurality of work procedure images in one work process. In this case, the work procedure images can be arbitrarily switched in addition to sequentially displaying the work procedure images.

  A list display unit for displaying a list of work procedure lists during display of the work procedure image by the work procedure image display unit, the list display unit corresponding to the work procedure image displayed by the work procedure image display unit It is preferable to display the work procedure to be performed and other work procedures in a distinguishable manner. In this case, it becomes easy for the operator to understand which work procedure the work currently being performed is in the work process.

According to the present invention, by coordinating the display of work procedure images and production management , an operator who works while looking at the work procedure images can reliably manage the production process while improving work supportability. it can.

Hereinafter, embodiments of a production management system of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows a network configuration of a production management system SS in a factory. This production management system SS connects a server (storage unit) S in which a production management database DB1, a work procedure image database DB2, etc. are stored and one or a plurality of terminal devices C used by a worker through a network such as a LAN. It is configured.

FIG. 2 is a block diagram showing a hardware configuration of the terminal device C. As shown in FIG. The terminal device C is configured by a computer mainly composed of a main body 110, a display 120, and an input device 130.
The main body 110 mainly includes a CPU 110a, a ROM 110b, a RAM 110c, a hard disk 110d, a reading device 110e, an input / output interface 110f, and an image output interface 110h. The CPU 110a, the ROM 110b, the RAM 110c, the hard disk 110d, and the reading The device 110e, the input / output interface 110f, and the image output interface 110h are connected via a bus 110i so that data communication is possible.

The CPU 110a can execute computer programs stored in the ROM 110b and computer programs loaded in the RAM 110c.
Then, the CPU 110a executes an application program 140a for realizing a function as a terminal in the production management system.

  The ROM 110b is configured by a mask ROM, PROM, EPROM, EEPROM, or the like, and stores a computer program executed by the CPU 110a, data used for the same, and the like.

The RAM 110c is configured by SRAM, DRAM, or the like. The RAM 110c is used to read out computer programs recorded in the ROM 110b and the hard disk 110d. Further, when these computer programs are executed, they are used as a work area of the CPU 110a.
The hard disk 110d is installed with various computer programs to be executed by the CPU 110a, such as an operating system and application programs, and data used for executing the computer programs.

  The reading device 110e is configured by a flexible disk drive, a CD-ROM drive, a DVD-ROM drive, or the like, and can read a computer program or data recorded on the portable recording medium 140. The portable recording medium 140 stores a computer program for causing the computer to function as a terminal of the production management system. The computer reads a necessary application program 140a and the like from the portable recording medium 140, and the application The program 140a and the like can be installed on the hard disk 110d.

The computer program such as the application program 140a is not only provided by the portable recording medium 140, but also from an external device that is communicably connected to the computer via an electric communication line (whether wired or wireless). It can also be provided through the telecommunications line. For example, the application program 140a and the like are stored in the hard disk of a server computer that provides an application program on the Internet, and it is possible to access the server computer, download the computer program, and install it on the hard disk 110d. It is.
In addition, an operating system that provides a graphical user interface environment such as Windows (registered trademark) manufactured and sold by US Microsoft Corporation is installed in the hard disk 110d. The computer program described in the present embodiment is assumed to operate on the operating system.

The input / output interface 110f includes, for example, a serial interface such as USB, IEEE 1394, and RS-232C, a parallel interface such as SCSI, IDE, and IEEE 1284, and an analog interface including a D / A converter and an A / D converter. ing. An input device 130 including a keyboard 130a, a mouse 130b, and / or a foot lever (foot operation unit) 130b is connected to the input / output interface 110f, and the user can input to the computer by using the input device 130. Can be done.
The image output interface 110h is connected to a display 120 configured by an LCD, a CRT, or the like, and outputs a video signal corresponding to image data given from the CPU 110a to the display 120. The display 120 displays an image (screen) according to the input video signal.

  The hardware configuration of the server S is almost the same as the hardware configuration of the terminal device C except for the foot lever 130c.

FIG. 3 shows functional blocks of the terminal device C realized by an application program or the like.
As illustrated in FIG. 3, the terminal device C includes a work process management unit 10 and a work procedure image display unit 20. The work process management unit 10 accesses the production management database DB1 of the server S and records information regarding each work process in the production process.
In addition, the work process management unit 10 can receive input of work results and defect information from an input device such as a keyboard 130a or a mouse 130b, and can record the received information in the production management database DB1. Furthermore, the work process management unit 10 can acquire information such as inspection results from the work target product or the inspection device of the product by communication, and can record the acquired information in the production management database DB1.

  The work procedure image display unit 20 accesses the work procedure image database DB2 of the server S, acquires an image (moving image or still image) indicating the work procedure of each work process, and displays the image on the display 120.

  Furthermore, the production management system according to the present embodiment includes a control unit 30 for linking the work process management unit 10 that performs production management and the work procedure image display unit 20 that indicates the work procedure to the worker. .

Fig.4 (a) has shown the flow of the production process about a certain production target product. The production process includes a plurality of work processes 1 to n, and each work process is a minimum unit of management by the work process management unit 10.
As shown in FIG. 4B, each work process includes one or a plurality of work procedures, and a work procedure image is prepared for each work procedure. That is, one or a plurality of work procedure images are associated with each work process and stored in the work procedure image database DB2.

  One work process refers to, for example, a work of assembling a certain part A to a target product being assembled. However, the work procedure actually performed by the worker for assembling the part A is, for example, (1) mounting the part A on the target product and screwing, (2) wiring between the part A and the target product, In many cases, one work process is composed of a plurality of work procedures, such as (3) performing piping between the part A and the target product, and (4) performing inspection for operation confirmation.

  In this embodiment, a work procedure image is prepared for each work procedure. For example, for one work process of assembling the part A, (1) a work procedure image explaining how to attach the part A to the target product and screw it, (2) how to wire the part A to the target product A plurality of work procedure images are prepared: a work procedure image to explain, (3) a work procedure image that explains how to pipe the part A and the target product, and (4) a work procedure image that shows how to inspect the operation. Has been.

  Even if it is one work process of assembling the part A, each work procedure constituting the one work process is a different work. Therefore, it is necessary to prepare a work procedure image for each work procedure. Work becomes easier. In other words, the worker performs a corresponding work while displaying a certain work procedure image, and when the work is completed, the worker switches to the next work procedure image and performs the next work, thereby performing the determined work procedure. It can be executed steadily sequentially.

On the other hand, as production management of the present embodiment, the entire work procedures (1) to (4) for assembling the part A to the target product being assembled are handled as one work process.
If an entire work process is described with one image, many work procedures are described with one image, and the display is inappropriate for steadily executing the determined work procedures sequentially. On the other hand, in the present embodiment, since the work procedure images are sequentially displayed in units of work procedures obtained by subdividing one work process, it is easy to steadily execute predetermined work procedures.

  It is also possible to perform production management in units of work procedures corresponding to one work procedure image. However, the explanation will be given in terms of the unit of work process to be managed as production management and the image display to assist the work of the worker. The unit of the work procedure to be performed does not always coincide.

Therefore, in the production management system of the present embodiment, a plurality of work processes defined from the viewpoint of production management (for example, a part A attachment work process, a part B attachment work process, a part C attachment work process,... A plurality of work procedure images that are subdivided from the viewpoint of ease of work support for the worker are prepared for each work process.
Note that the number of work procedure images included in each work process is not constant, and the number of images can be set flexibly for each work process. Further, the number of work procedure images corresponding to one work process may be one.

5 and 6 show the flow of processing by this system. First, when a login request (input of user ID and password) is received from the worker (step S1), the system performs user authentication (step S2).
When the system is successfully authenticated (step S3), the system accepts a work instruction code (step S4). The work instruction code is a code described in a work instruction sheet distributed to each worker before work, and is used to specify a work in the production process that each worker is responsible for. The work instruction code is input from the keyboard 130a or the like.

  When the system receives the work instruction code, the control unit 30 causes the work process management unit 10 of the system to display the work process management screen D1 shown in FIG. 7 (step S5; start of work process management mode). On the work process management screen D1, a product name display part H1 to be worked, a list display part H2 of work processes, and the like are displayed.

When the operator inputs an operation start instruction for an operation process to be performed from now on using an input device such as the keyboard 130a or the foot lever 130c, and the system accepts this (step S6), the control unit 30 performs the system operation. The procedure image display unit 20 displays a work procedure image corresponding to the work process to be started on the display 120 (step S7; start of the work procedure image display mode).
The work procedure image display unit 20 acquires one or a plurality of work procedure images (moving images or still images) corresponding to the work process from the work procedure image database DB2, and sequentially displays the acquired images.

In the present embodiment, the display 120 is configured to switch between a work process management screen D1 (work process management mode) and a work procedure image (work procedure image display mode), and display the work procedure image. Then, the work process management screen D1 becomes invisible, and when the work process management screen D1 is displayed, the work procedure image becomes invisible. Thus, the work process management screen D1 and the work procedure image are switched and displayed, so that the worker can easily grasp what to do.
That is, if the work process management screen D1 is displayed, the system is in the work process management mode, and it is understood that the operator should perform a system operation (work process management process) for work process management. If an image is displayed, the system is in the work procedure display mode, and it is understood that work for production (such as assembly work) should be performed.

When a certain work process starts, the first work procedure image in the work process is displayed on the display 120. If the work procedure in a certain work process is 1 to j (see FIG. 4), a total of j work procedure images are displayed for the work process.
Specifically, the worker performs work while viewing the displayed work procedure image. When the work is completed, for example, the operator operates the foot lever (completion input unit) 130c with his / her foot to perform a completion input for ending the display of the work procedure image to the system.
In this embodiment, since completion input can be performed by foot operation, an operator can perform manual operation for performing a plurality of work procedures in one work process by performing completion input of each work procedure at any time. A series of work procedure images can be executed continuously without stopping.

When the completion input for the work procedure image other than the final work procedure image in the work process to be worked is performed (step S9), the control unit 30 causes the work procedure image display unit 20 to use the next work procedure in the work process. A work procedure image corresponding to is displayed (step S7).
When the above procedure is repeated and work procedure images in the work process are sequentially displayed, and a completion input for the j-th work procedure image (final work procedure image of the work process: step S8) is received (step S10). The control unit 30 ends the display of a series of work procedure images in the work process (step S11; end of the work procedure image display mode), and the work process management image D1 is switched and displayed instead of the work procedure image (work). Start of process management mode).

  When the system enters the work process management mode, the work process management unit 10 receives an input of work results of the completed work process (step S12). The input of the work result may be performed by the operator inputting the numerical value (dimension etc.) of the assembly result from the keyboard 130a or the like, or the inspection result of the target product is worked from the inspection function unit of the work target product. As a result, it may be acquired by communication, or an inspection result may be acquired as a work result by communication from an apparatus that inspects the target product.

Subsequently, the work process management unit 10 determines the acquired work result (step S13). The work process management unit 10 determines the acquired work result based on a predetermined determination criterion, and generates a determination result of pass (G) or fail (NG).
Thereafter, the work process management unit 10 performs work process management processing for registering the completion of the work process in the production management database DB1 together with the determination result (step S14). In the present embodiment, the completion information of each work process registered in the production management database includes the worker name, work process information for specifying the work process, determination result, work date, and work (completion) time. .

  When the work result is acceptable (step S15), the next work process is selected by the worker (step S17), and when the work start instruction for the work process is input (step S6), the first work process is started. The work procedure image is displayed, and the work procedure image display mode is started. Also in the next work process, work procedure images are sequentially displayed in the same manner as described above (steps S7 and S9). When the completion input for the final work procedure image in the next work process is made (step S10), the work procedure image is displayed. The display mode ends and the work process management mode is entered.

  When the work process is performed as described above and all work processes are completed (step S16), a new work instruction code can be received (step S4) to start a new work or to log out. (Step S18).

When the determination result of each work process is rejected (NG), when the system receives an instruction to display a defect information input screen from the operator (step S19), the work process management unit 10 displays a defect information input screen (illustrated). (Omitted) is displayed on the display 120 (step S20).
On the defect information input screen, the worker can input a defect phenomenon, a cause of defect, and the like as defect information. When the system accepts defect information input (step S21), the worker information The work information indicating the work process is registered in the production management database DB1 (step S22).

Thereafter, when failure handling completion information indicating that the handling of the failure occurring in the work process is completed is input to the system by an operator or the like (for example, clicking the “failure handling” button on the failure information input screen) ( In step S23), the work result of the work process registered in the production management database DB1 = “NG” is cleared, and the work process can be performed again (step S5).
As described above, when the work result is rejected (NG), the work process is repeated until the work is passed, so that defective products can be reduced. Moreover, since the display of the work procedure image is repeated when the work process is repeated, a reliable work can be expected.

  FIG. 8 shows a work display screen D2 for displaying a work procedure image in the work procedure image display mode. The work display screen D2 displays an image display unit H11 that displays a work procedure image, an explanatory text display unit H12 that displays explanatory text related to the displayed work procedure image, and a list that shows a list of work procedures. A list display section H13.

  In the list display portion H13, in addition to the work procedure corresponding to the work process being worked, the work procedure of the work process before and after the work process is also displayed. The work procedure 50 corresponding to the work procedure image displayed on the image display unit H11 is highlighted (highlighted) in the list display unit H13, and is displayed so as to be distinguishable from other work procedures. Thereby, the worker can easily grasp which work procedure is being executed in the series of work procedures.

In addition, it is possible to select an arbitrary work procedure from one or a plurality of work procedures corresponding to the work process in progress among the work procedures displayed in the list display portion H13. The selection operation can be performed by selecting one of the work procedures displayed on the list display portion H13 with the mouse 130b.
In the completion input by the completion input unit 130c, the work procedure images are sequentially switched according to the work procedure. However, when the work is to be performed again, the worker selects the desired work procedure, thereby the work procedure image display unit 20. Can display the previous work procedure image and the like, and the flexibility of display is increased.
However, since it is not possible to select a work procedure that corresponds to a work process other than the current work process, it is possible to prevent the current work process from being completed and to move to another work process, which is consistent with production management. Can keep sex.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible in the range which does not deviate from the summary.
