Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work site in a production line in which various works flowing on a line are sequentially processed into a product to form one unit by combining a plurality of kinds of works. Work instruction display configured so that corresponding work instruction data is sent from the main control unit to each terminal in the order of the process plan in response to a work instruction request from each terminal installed in the work place of each process. Regarding the system.

[0002]

2. Description of the Related Art Conventionally, work instructions have been issued to each process at a work site by distributing a copy of a design drawing of each product to a worker in each process in advance.

That is, the site worker processes the work flowing on the line while looking at the design drawing of the portion he is in charge of among the distributed design drawings.

As described above, in the conventional work instruction method, since it is necessary to make a copy of the design drawing only for the workers in each process, a large amount of copy paper is required, and the work flowing on the line suddenly occurs. If there was a change, there was confusion at the work site.

Therefore, the inventors of the present invention respond to the work instruction data from the factory host computer to each of the terminals in response to a work instruction request from each terminal installed in the work place of each process on the work site. Provide a work instruction display system for transmitting the order of process plans (Japanese Patent Application No. 3-118).
518).

In this work instruction display system, only the necessary work in the design drawing is displayed on the terminal of each process at the work site. Therefore, when creating the work instruction data, it is necessary to cut out the read image data of the design drawing for each work.
This cutting work includes (1) reading the drawing, (2) displaying the read drawing on the CRT screen, (3) specifying cutout points and unit sizes, and (4) CRT screen for only the cutout part. It is performed for all the works of all the design drawings by the procedure of displaying on the top, (5) editing image data on the CRT screen, and (6) storing the data.

When the image data of a drawing is cut out in units of work, if the work is cut out according to the size of the work, the related information (information such as connection relationship and wiring) with the adjacent work cannot be determined, so Is cut out larger than the work size and displayed on the terminal installed at the site.

[0008]

As described above, in the conventional work instruction display system, the work drawing displayed on the terminal is displayed in a larger size than the actually required work size including the adjacent work parts. The problem remains that the boundary between the work to be performed and the adjacent work is difficult to see on the screen. Therefore, the site worker needs to perform the work while carefully watching the displayed work drawing, and the workability is poor.

The present invention has been made in view of the above circumstances, and an object thereof is to display a boundary line between a work and an adjacent work when displaying an image drawing of the work on each terminal on site. It is to provide a work instruction display system according to the above.

[0010]

In order to solve the above problems, the work instruction display system of the present invention sequentially processes various works flowing on a line in order to form one unit by combining a plurality of kinds of works. In the production line where the product is commercialized, work instruction data corresponding to each terminal is sent from the main control unit by a work instruction request from each terminal installed at the work place of each process on the work site. A system configured to send data in the order of process plans, creates data for each work based on the read design drawing, and sets the range of works displayed on one screen of each terminal to adjacent works. Keys are the edit control unit that expands to batch and performs batch cutting processing, drawing codes corresponding to various design drawings and each work number included in the drawings. And the size and the reference coordinates of the work,
A first storage unit that stores the cut-out file of each work edited by the edit control unit as work instruction data for each work, and a grid origin that serves as a reference for size, reference coordinates, and work boundary calculation of each work. A second storage unit that stores a fixed file in which each data such as coordinates is stored in advance, and an environment definition file that stores each information of the thickness and color of the boundary line, and the second storage unit. A main control unit that performs control to write grid starting point coordinates from the finalized file, determine the coordinates of the work boundary starting point from the grid starting point coordinates, and write the obtained coordinates of the work boundary starting point to the finalized file, and a work site. In response to a read instruction from each terminal installed in the work place of each process, the process of displaying the file in its own process among the finalized files stored in the second storage unit. A third storage unit that reads out a fixed file to be read and also reads and stores an environment definition file stored in the second storage unit, and a work instruction request from each of the terminals, and the first storage unit. The work instruction data stored in the unit is read out, and the drawing data for each work necessary for each process is displayed on the display unit, and the display is performed from the confirmation file and the environment definition file stored in the third storage unit. And a terminal control unit for performing control to display a boundary line between a work to be worked in its own process and an adjacent work on the drawn drawing data, in either the main control unit or the terminal control unit, The other three points are obtained from the work boundary line starting point and the work size.

[0011]

The design drawing is read by, for example, a reading device, converted into image data, and stored in the first storage section. Further, the size and reference coordinates of each work are stored in advance in the first storage unit with the drawing code corresponding to each design drawing and each work number included in the drawing as keys.

The editing control unit creates data for each work based on the design drawing read in this way, and the range of the work displayed on one screen of each terminal installed at the work site is adjacent to the work. Expand to and perform batch cutting processing. This batch cutting process will be described more specifically.

That is, the operator inputs a drawing code and designates the reference coordinates of an arbitrary work indicated by the drawing code as a cutout point. This cutout point is
For example, the upper left corner of the work located in the upper left of the design drawing. The editing control unit reads the design drawing corresponding to the drawing code from the first storage unit and displays it on the screen based on the input drawing code and the designation of the cut-out point, and the image data of the design drawing displayed on the screen. The workpieces included in the design drawing are sequentially cut out from the cutout points designated above. That is, one work including the cut point is cut out, and then the next one work adjacent to this work is cut out. At this time, the cut-out point of the next work can be easily obtained by calculation processing from the size of each work and the reference coordinates stored in the first storage unit. The edit control unit sequentially performs such an operation on adjacent works, and when the cutting of the last work is completed, the image data of each work, the work number of the drawing code, and the reference coordinates are used as work instruction data as the first work instruction data. Stored in the storage unit of.

Further, the second storage unit stores a size of each work, a reference coordinate, a fixed file in which each data such as a grid starting point coordinate serving as a reference for the work boundary calculation is stored in advance, and a thickness and a color of the boundary line. An environment definition file is stored in which each item of information is stored.

Further, the main control unit obtains the grid starting point coordinates from the finalized file stored in the second storage unit, obtains the coordinates of the work boundary line starting point from the grid starting point coordinates, and finds the obtained work boundary line starting point. Controls to write the coordinates of to the finalized file. When the other three points are also obtained by the main control unit, the main control unit determines the work boundary line coordinates of the other three points from the obtained coordinates of the work border line starting point and the work size stored in the finalized file. Then, control is performed to write the coordinates of the obtained work boundary line to the finalized file.

As a result, when the terminal installed at the work place of each process on the work site is started up, the terminal control unit is stored in the second storage unit in response to the read instruction request to the main control unit. Of the finalized files, the finalized file to be displayed in its own process is read out, and the environment definition file also stored in the second storage unit is read out and stored in the third storage unit. Thereafter, the terminal control unit reads the work instruction data stored in the first storage unit, displays the drawing data for each work required for each process on the display unit, and stores the work instruction data in the third storage unit. A boundary line between a work to be worked in its own process and an adjacent work is displayed on the displayed drawing data from the determined file and the environment definition file. For example, when the environment definition file stores data of red as the display color of the border and thick line as the type of the border, the border is displayed as a thick red line.

As a result, the on-site worker of each process can easily confirm his / her own work range by the boundary line shown in the drawing data displayed on the screen, and the work efficiency is improved. .

The main control section 21 to which the output of the input section 24 is guided and the second storage section 22 are bidirectionally connected, and the output of the main control section 21 is guided to the display section 23. It has a broken structure.

2 and 3 show a part of the data of the information file stored in the second storage section 22.

In this information file, data such as the size of each work and reference coordinates (X-axis coordinate, Y-axis coordinate) is registered by using the drawing code and the work number as keys, and the work boundary line coordinates described later. Data such as is registered, and the finalized file is configured by each of these data.

The main control section 21 and the terminal control section 31 of each terminal C ... Installed at the work place of each process on the work site are bidirectionally connected.

Each of the terminals C ... Has the same structure and is composed of the terminal control section 31, the operation section 32, the third storage section 33, and the display section 34.

The operation section 32 is provided with a "necessary" button for requesting transmission to the host computer B, and at the site, it is possible to simply operate this "necessary" button.

Further, the third storage unit 33 is necessary for the own process transferred from the environment definition file stored in the second storage unit 22 and the finalized file when the terminal is started up. A fixed file.

Further, the main controller 2 of the host computer B
The work instruction data sent via 1 is displayed on the display unit 34 via the terminal control unit 31. At this time, the work instruction data stored in the third storage unit 33 Refer to the confirmation file and environment definition file,
On the drawing data displayed on the display unit 34, a boundary line between a work to be worked in its own process and an adjacent work is displayed. For example, when the environment definition file stores data of red as the display color of the border and thick line as the type of the border, the border is displayed as a thick red line.

Next, the operation of the work instruction display system having the above-described configuration is divided into (1) batch cutout processing of image data in the editing machine A, and (2) boundary line display operation in the host computer B and the terminal C. Each will be explained. However, in this embodiment, 4 including the work boundary line starting point
A case where the main control unit 21 obtains the coordinates of points will be described.

(1) Batch cutting processing operation of image data in the editing machine A.

FIG. 4 shows an operation flowchart of the editing machine A. Hereinafter, description will be given with reference to FIG.

When the editing machine A is started up, the editing machine A outputs a transmission request for the information file stored in the second storage section 22 to the main control section 21 of the host computer B. The main control unit 21 reads the information file stored in the second storage unit 22 according to this transmission request, and transmits this to the editing control unit 13. The edit control unit 13 stores the received information file in the first storage unit 15.

After that, the operator sets the design drawing to be edited in the reading unit 11 and operates the input unit 12 to activate the reading unit 11. As a result, the editing control unit 13 controls the reading unit 11 to start reading all the set design drawings (step S11). The read design drawings are stored as image data in the first storage unit 15 in the order of reading (step S12). If the design drawing to be read remains, steps S11 to S13 are repeated. If the design drawing to be read does not remain, the operation proceeds to the next step S14.

FIG. 5 shows an example of the design drawing read in this way. This design drawing is a plan view of a unit house, and is composed of a combination of six works indicated by circled numbers.

When all the design drawings have been read,
Next, the operator operates the input unit 12 to display the image data of the design drawing stored in the first storage unit 15 on the display unit 16.
To display. Then, in this state, the operator operates the input unit 12 to input the drawing code corresponding to the image data.

The edit control unit 13 determines whether the input code exists in the information file stored in the first storage unit 15, and if so, advances the operation to specify the cutout point (step S15). ).

To specify the cut-out point, as shown in FIG. 5, the input unit 12 is operated on the display unit 16 and the upper left corner of the work having the smallest number (shown as a partially enlarged view in the drawing). ) Is specified. Thereby, the reference coordinates on the image data can be obtained. The obtained coordinates are stored in the first storage unit 15 (step S15).

If the image data remains in the first storage section 15, steps S14 to S16 are repeated. If the image data does not remain, the operation proceeds to step S17.

That is, from the input section 12 to the edit control section 13
When a cutout start instruction is given to, the edit control unit 13 reads the image data and the cutout point corresponding to the image data stored in the first storage unit 15, and sends it to the file creation unit 14. The file creation unit 14 cuts out in units of work from the corresponding cutout points of the image data read from the first storage unit 15 (step S1).
7).

That is, in the confirmed file of the information file stored in the second storage unit 22, as shown in FIG. 2, with the drawing code and the work number as keys, the size of the work and the reference coordinates are stored. Since it is registered, the coordinates of the upper left corner of the work with the smallest number in the design drawing can be specified by specifying the cutout point. For example, the X-axis = 010 in the information file of the work No. 1
Assuming that the reference coordinates of 10, Y-axis = 99990 are registered, the point designated for cutout is (01010,00900) on the image data. However, the work boundary line coordinates are not written in the finalized file at this time.

When the cut-out points of the work No. 1 can be specified in this way, the cut-out points on the image data of the other works of the same drawing code can be easily obtained by calculation.
From the cut-out point of each work obtained by this calculation, cutting is performed according to the size of the work in ascending order of the work number.

At this time, if the work is cut out according to the work size, information related to the adjacent work (for example, information on wiring connection) cannot be known. Therefore, as shown by a broken line in FIG. 6, the work size is larger than the work size. cut.

The image data of each work, the drawing code and the work number cut out by the file creating unit 14 in this manner are again stored in the first storage unit 15, and each terminal C of each process is ... The work instruction data to be sent to each work is held for each work (step S18).

With the above, the batch cutting process of the image data is completed.

(2) Host computer B and terminal C
Border display operation in.

FIG. 7 shows an operation flowchart of the host computer B. The operation of the host computer B will be described below with reference to FIG.

After the batch cut-out processing of the image data is completed, the operator inputs a request for reading the fixed file from the input unit 24 of the host computer B. The main control unit 21 receives the read request signal from the second storage unit 22 to the finalized file shown in FIG. 2 (work boundary coordinates are not written in the finalized file at this time).
Is read and processing is performed for each work (step S2
1).

That is, the main control unit 21 obtains the starting point coordinates of the grid (the line displaying the area) which is the reference for the calculation of the work boundary line from the read finalized file (step S22), and is shown in FIG. As described above, the X coordinate (-120 mm) and the Y coordinate (120 mm) are added to the grid starting point coordinates to obtain the coordinates of the upper left corner that is the starting point of the work boundary line (step S23). Here, the numerical value of ± 120 mm added to the X-coordinate and the Y-coordinate is the dimension of the steel frame framing for connecting the adjacent works.

Since the vertical and horizontal dimensions of the work can be obtained from the finalized file (step S24), the coordinates of the upper left corner of the work boundary line are used as the starting point, and the reference coordinates of the border line are calculated from the vertical and horizontal dimensions of the work. Coordinates of three points other than are calculated (step S25). Then, each coordinate of the four points of the work boundary line obtained by the calculation is written in the finalized file (step S26).

The main control section 22 performs such processing for all the confirmed files and ends the operation.

FIG. 9 shows an operation flowchart of the terminal C. Hereinafter, the operation of the terminal device C will be described with reference to FIG.

The terminal control section 31 of the terminal C requests the main control section 21 to transmit the environment definition file stored in the second storage section 22 shown in FIG. S31). This transmission request is made by depressing the "necessary" button of the operation unit 32 once.

In response to the transmission request from the terminal control unit 31, the main control unit 21 reads the environment definition file from the second storage unit 22 and sends it to the terminal control unit 31 of the terminal device C. The terminal control unit 31 receives the environment definition file transmitted from the main control unit 21, and stores this in the third storage unit 33 (step S32).

Next, when a display switching request is made by pressing the "necessary" button of the operation unit 32, for example, the terminal control unit 31 instructs the main control unit 21 to confirm the information stored in the second storage unit 22. A file transmission request is made (step S33).

In response to the transmission request from the terminal control unit 31, the main control unit 21 reads the corresponding finalized file from the second storage unit 22 and sends it to the terminal control unit 31. Further, the main control unit 21 reads out the corresponding work instruction data from the work instruction data stored in the first storage unit 15 of the editing machine A in response to the transmission request from the terminal control unit 31, and controls the read work instruction data. It is transmitted to the unit 31.

The terminal control section 31 receives the confirmed file transmitted from the main control section 21, and stores it in the third storage section 33 (step S34). Further, the terminal control unit 31 causes the display unit 34 to display the work drawing shown in the work instruction data transmitted from the main control unit 21. As described above, the work drawing at this time is a display that includes not only the work drawing necessary for the work but also a part of the adjacent work drawing.

Thereafter, the terminal control section 31 determines the coordinates of the four corners of the boundary line stored in the finalized file stored in the third storage section 33, the work size, and the boundary line stored in the environment definition file. The work boundary line is calculated and displayed on the display unit 34 on the basis of the respective pieces of thickness and color information (step S).
35).

That is, a boundary line between a work to be worked in its own process and an adjacent work is displayed on the work drawing displayed on the display unit 34. Since the environment definition file stores each data of red as the display color of the boundary line and thick line as the type of the boundary line, the display unit 34 should display the boundary line with the thick red line on the work drawing. become.

As a result, the on-site worker of each process can easily confirm his / her work range by the boundary line shown in the drawing data displayed on the screen, and the work efficiency is improved. .

In the above embodiment, the border line is displayed as a thick red line, but it is possible to change the registered contents of the environment definition file to any color that can be displayed at present. is there. Further, instead of changing the color and thickness of the boundary line, the brightness of the boundary line may be made higher than the others to clarify the work range.

In the above embodiment, the case where the coordinates of four points including the work boundary line starting point are obtained by the main control unit 21 has been described, but the other three points excluding the work boundary line starting point are determined by the terminal control unit. If it is performed by 31, the amount of transfer data between the main control unit 21 and the terminal control unit 31 can be reduced.

[0065]

According to the work instruction display system of the present invention, the cut-out file of each work edited by the editing control unit is stored as work instruction data in the first storage unit for each work, and the second storage unit. The four-sided work boundary line coordinates obtained by calculation from the finalized file and the environment definition file stored in are written in the finalized file, and the finalized file and the environment definition file and the first file stored in the second storage unit are stored.
Since it is configured to display the boundary line between the work to be worked in the process and the adjacent work on the drawing data displayed on the display unit of the terminal, from the work instruction data stored in the storage unit of The field worker of each process can easily confirm his / her work range by the boundary line shown in the drawing data displayed on the screen, and the work efficiency is improved.
