DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production line in which a variety of workpieces flowing on a line are sequentially processed and commercialized to form one unit by combining a plurality of types of workpieces. A work instruction display configured so that, in response to a work instruction request from each terminal installed at the work place of each process, the main control unit sends corresponding work instruction data to each terminal in the order of the process plan. About the system.

[0002]

2. Description of the Related Art Conventionally, work instructions for each process at a work site have been issued in such a manner that the copied design drawings of each product are distributed in advance to the operators of each process.

[0003] That is, a site worker processes a workpiece flowing on a line while looking at a design drawing of a part in charge of the distributed design drawing.

As described above, in the conventional work instruction method, since it is necessary to make copies of the design drawings only for the workers in each process, a large number of copy sheets are required, and the work flowing on the line is suddenly generated. Any change would have caused confusion at the work site.

Accordingly, the present inventors requested a work instruction request from each terminal installed at the work site of each process in the work site, and sent a corresponding work instruction data from the factory host computer to each terminal. Are provided in the order of the process plan (Japanese Patent Application No. 3-118).
518).

In this work instruction display system, only necessary works in a design drawing are displayed on a terminal of each process at a work site. Therefore, when creating the work instruction data, it is necessary to cut out the image data of the read design drawing into work units.
The cut-out work includes (1) reading a drawing, (2) displaying the read drawing on a CRT screen, (3) specifying a cut-out point and a unit size, and (4) CRT screen of only a cut-out portion. This is performed for all works in all design drawings by a procedure such as display on the top, (5) editing of image data on the CRT screen, and (6) storage of 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, information related to an adjacent work (information such as connection relations and wiring) cannot be determined. 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 larger than the actually required work size including the adjacent work part. However, there has been a problem that the boundary between a work to be performed and an adjacent work is difficult to understand on a screen. Therefore, it is necessary for the site worker 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 at the site. Another object of the present invention is to provide a work instruction display system.

[0010]

In order to solve the above-mentioned problems, a work instruction display system according to 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 a production line that is manufactured by applying a command, a work instruction request from each terminal installed at the work place of each process at the work site causes a work instruction data corresponding to each terminal from the main control unit. A system configured to be sent out in the order of a process plan, wherein data is created for each work based on the read design drawings, and the range of the work displayed on one screen of each of the terminals is set to the adjacent work. An editing control unit that performs batch cutout processing by expanding to the maximum, and drawing codes corresponding to various design drawings and each work number included in the drawings as keys. 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 editing control unit as work instruction data for each work, and a grid origin serving as a reference for calculating the size, reference coordinates, and work boundary of each work A second storage unit for storing a defined file in which data such as coordinates are stored in advance, and an environment definition file in which information on the thickness and color of the boundary line is stored; and a second storage unit for storing the environment definition file. A main control unit for obtaining grid starting coordinates from the fixed file, obtaining coordinates of a work boundary starting point from the grid starting coordinates, and writing the obtained coordinates of the work boundary starting point to the fixed file; In accordance with a readout instruction from each terminal installed at the work place of each step, the finalized file stored in the second storage unit is displayed in its own step. A third storage unit that reads out and stores an environment definition file stored in the second storage unit while reading a confirmed file to be performed; and a first storage unit that receives a work instruction request from each of the terminals. The work instruction data stored in the storage unit is read out and the drawing data for each work required for each process is displayed on the display unit, and the display data is displayed from the finalized file and the environment definition file stored in the third storage unit. A terminal control unit for performing control to display a boundary line between a work to be operated in its own process and an adjacent work on the drawn drawing data, and in any one of the main control unit or the terminal control unit, The other three points are determined 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 unit. In the first storage unit, the size of each work and the reference coordinates are stored in advance using a drawing code corresponding to each design drawing and each work number included in the drawing as a key.

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

That is, the operator inputs a drawing code and designates a reference coordinate of an arbitrary work indicated by the drawing code as a cutout point. This cut point is
For example, the upper left corner of the work located at the upper left of the design drawing. The editing control unit reads out the design drawing corresponding to the drawing code from the first storage unit based on the input drawing code and the designation of the cut-out point, displays the design drawing on the screen, and displays image data of the design drawing displayed on the screen. From the cutout point specified above, each work included in the design drawing is cut out sequentially. That is, one work including the cut-out 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 from the size and the reference coordinates of each work stored in the first storage unit by arithmetic processing. The editing control unit sequentially performs such operations on the 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 first instruction data. In the storage unit.

The second storage unit includes a fixed file in which data such as the size of each work, reference coordinates, grid starting coordinates used as a reference for calculating a work boundary, and the like are stored in advance. An environment definition file storing the above information is stored.

Further, the main control unit obtains grid starting point coordinates from the fixed file stored in the second storage unit, obtains the coordinates of the work boundary line starting point from the grid starting point coordinates, and obtains the calculated work boundary line starting point. Control to write the coordinates of. When the main control unit also obtains the other three points, the main control unit calculates the work boundary line coordinates of the other three points based on the obtained coordinates of the work boundary start point and the work size stored in the finalization file. Then, control is performed to write the obtained coordinates of the work boundary line into the determined file.

Thus, when the terminal installed in the work place of each process of the work site is started up, the terminal control unit is stored in the second storage unit in response to a read instruction request to the main control unit. Among the determined files, a determined file to be displayed in its own process is read, and an environment definition file also stored in the second storage is read and stored in the third storage. Thereafter, the terminal control unit reads out 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 drawing data in the third storage unit. Based on the determined file and the environment definition file, a boundary line between a work to be worked in its own process and an adjacent work is displayed on the displayed drawing data. For example, if the environment definition file stores red data as the display color of the boundary line and bold line data as the type of the boundary line, the boundary line is displayed as a red bold line.

[0017] Thus, the 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, thereby improving work efficiency. .

[0018]

5 is a bidirectional connection. Further, the editing control unit 13 and the main control unit 21 of the host computer B are connected bidirectionally.

The host computer B has an editing control unit 13
A main control unit 21 that transmits and receives data to and from a fixed file in which data such as the size of each work on the drawing, reference coordinates, grid starting point coordinates serving as a reference for work boundary calculation, and the like are stored in advance; A second storage unit 22 that stores an environment definition file in which information of line thickness and color is stored,
A display unit 23 composed of a CRT or the like for displaying data input / output status, and an input unit 24 for the operator to input various information
And is constituted by.

The main control unit 21 to which the output of the input unit 24 is led and the second storage unit 22 are connected bidirectionally, and the output of the main control unit 21 is transmitted to the display unit 23. It has a configuration in which

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

In this information file, data such as the size of each work, reference coordinates (X-axis coordinates, Y-axis coordinates), etc. are registered using the drawing code and the work number as keys, and work boundary line coordinates described later. And the like are registered, and these data constitute a finalized file.

Further, the main control unit 21 and the terminal control units 31 of the terminals C... Installed at the work place of each process at the work site are connected bidirectionally.

Each terminal C has the same configuration, and is composed of the terminal control unit 31, an operation unit 32, a third storage unit 33, and a display unit 34.

The operation section 32 has a "required" button for requesting transmission to the host computer B. At the site, a simple operation of pressing the "required" button is sufficient.

When the terminal is started, the third storage unit 33 stores the environment definition file stored in the second storage unit 22 and the finalized file necessary for its own process transferred. Is stored.

The main control unit 2 of the host computer B
1 is displayed on the display unit 34 via the terminal control unit 31. At this time, the work instruction data of the own process stored in the third storage unit 33 is displayed. Referring to the confirmation file and the 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, if the environment definition file stores red data as the display color of the boundary line and bold line data as the type of the boundary line, the boundary line is displayed as a red bold line.

Next, the operation of the work instruction display system having the above-described configuration is divided into (1) an image data batch cutting operation in the editing machine A, and (2) a boundary line displaying operation in the host computer B and the terminal C. Each will be described. However, in the present embodiment, 4 including the work boundary line starting point.
A case where the coordinates of a point are obtained by the main control unit 21 will be described.

(1) Batch processing of image data in editing machine A

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

When the editing machine A is started, the editing machine A outputs a request for transmitting 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 in response to the transmission request, and transmits the information file to the editing control unit 13. The editing control unit 13 stores the received information file in the first storage unit 15.

Thereafter, 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. Thus, the editing control unit 13 controls the reading unit 11 and starts reading all set design drawings (step S11). The read design drawings are stored in the first storage unit 15 in the reading order as image data (step S12). If there are any design drawings to be read, steps S11 to S13 are repeated. If there are no design drawings to be read, the operation proceeds to the next step S14.

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

When reading of all the design drawings is completed,
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 be displayed. Then, in this state, the operator operates the input unit 12 to input a 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, proceeds to specify a cutout point (step S15). ).

As shown in FIG. 5, the method of designating the cut-out point is to operate the input unit 12 on the display unit 16 and to operate the input unit 12 at the upper left corner of the work having the smallest number (shown as a partially enlarged view in the drawing). ). This makes it possible to obtain reference coordinates on the image data. The obtained coordinates are stored in the first storage unit 15 (Step S15).

If image data remains in the first storage section 15, steps S14 to S16 are repeated. If no image data remains, the operation proceeds to step S17.

That is, from the input unit 12 to the editing control unit 13
When the cut-out start instruction is given to the user, the edit control unit 13 reads out the image data stored in the first storage unit 15 and the corresponding cut-out point, and sends it to the file creation unit 14. The file creating unit 14 cuts out the image data read out from the first storage unit 15 for each work from the corresponding cutout point (step S1).
7).

That is, in the fixed file of the information file stored in the second storage unit 22, the size of the work and the reference coordinates are set using the drawing code and the work number as keys as shown in FIG. 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 information file of the work No. 1 has X-axis = 010
Assuming that reference coordinates of 10, Y-axis = 00900 are registered, the point designated to be cut out 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 point 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, respectively.
From the cut-out point of each work obtained by this calculation, cut-out is performed according to the size of the work in ascending order of the work number.

At this time, if the image is cut out according to the size of the work, information related to the adjacent work (for example, information on wiring connection, etc.) cannot be understood, and therefore, as shown by a broken line in FIG. cut.

The image data, drawing code, and work number of each work cut out in the file creating section 14 in this way are stored again in the first storage section 15, and each terminal C in each step is processed. Is held for each work as work instruction data sent to the work (step S18).

Thus, the batch cutout processing 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. Hereinafter, the operation of the host computer B will be described with reference to FIG.

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

That is, the main control unit 21 acquires the starting coordinates of a grid (line for displaying an area), which is a reference for calculating a work boundary line, from the read determined file (step S22), as shown in FIG. By adding the X coordinate (-120 mm) and the Y coordinate (120 mm) to the grid starting point coordinates, the coordinates of the upper left corner serving as the starting point of the work boundary line are obtained (step S23). Here, the numerical value of ± 120 mm added to the X coordinate and the Y coordinate is a dimension of a steel frame for connecting adjacent works.

Further, since the vertical and horizontal dimensions of the work are obtained from the finalized file (step S24), starting from the coordinates of the upper left corner of the work boundary line, the reference coordinates of the boundary are obtained from the vertical and horizontal dimensions of the work. The coordinates of the other three points are obtained by calculation (step S25). Then, the coordinates of the four points of the work boundary line obtained by the calculation are written in the finalized file (step S26).

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

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

When the power is turned on, the terminal control unit 31 of the terminal C requests the main control unit 21 to transmit the environment definition file stored in the second storage unit 22 shown in FIG. S31). This transmission request is made by, for example, depressing once the “necessary” button of the operation unit 32 once.

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

Next, when there is a display switching request by, for example, depressing the “necessary” button of the operation unit 32, the terminal control unit 31 instructs the main control unit 21 to store the confirmation 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 fixed file from the second storage unit 22, and transmits this file to the terminal control unit 31. In response to a transmission request from the terminal control unit 31, 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, 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). In addition, the terminal control unit 31 displays the work drawing indicated by the work instruction data transmitted from the main control unit 21 on the display unit 34. As described above, the work drawings at this time include not only the work drawings necessary for the work but also a part of the adjacent work drawings.

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

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

Thus, the 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, thereby improving work efficiency. .

In the above embodiment, the boundary line is displayed as a bold red line. However, by changing the registered contents of the environment definition file, any color that can be displayed at present can be obtained. is there. Further, instead of changing the color and thickness of the boundary line, the working range may be clarified by increasing the luminance of the boundary line more than the others.

Further, in the above-described embodiment, the case where the coordinates of four points including the starting point of the work boundary line are determined by the main control unit 21 is described. If the processing is performed at 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, a cut-out file of each work edited by the edit control unit is stored as work instruction data in a first storage unit for each work, and a second storage unit is provided. The coordinates of the four corners of the work boundary calculated by the fixed file and the environment definition file stored in the second storage unit are written into the fixed file, the fixed file and the environment definition file stored in the second storage unit, and the first file.
Since the boundary line between the work to be worked in its own process and the adjacent work is displayed on the drawing data displayed on the display unit of the terminal from the work instruction data stored in the storage unit of the terminal. On the other hand, the site worker in 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 working efficiency is improved.
