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 various workpieces flowing on a line are sequentially processed and commercialized, and a work instruction from each terminal installed at a work place of each process in a work site. The present invention relates to a work instruction display system configured to transmit corresponding work instruction data to each terminal from a main control unit in response to a request.

[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.

Therefore, the present inventors store drawing data and marking data corresponding to each work in a storage unit in advance and store the drawing data and marking data corresponding to the display unit of each terminal installed in each process. By reading and displaying data, a work-instruction display system is provided in which the entire factory can be made paperless and a sudden change in the work flowing on the line can be dealt with immediately.

In this work instruction display system, when creating drawing data and marking data for each work, an operator identifies a necessary part for each process while looking at the drawing for each work, and places it in the identified part. The work of marking individually was performed.

[0007]

That is, in the above-mentioned work instruction display system, the operator needs knowledge of the assembling work in each process in order to perform the marking. That is, there is a problem that a beginner who has no knowledge of the assembling work in each process cannot perform marking.

In addition, even if the same work is used, if the whole plan using the work is different, the number of markings becomes very large because the marking locations in each step are slightly different. For this reason, even an operator who has knowledge of the assembling work in each step cannot actually perform detailed marking, but only applies marking to almost any place. Therefore, the worker on the site needs to look at the drawing and the marking displayed on the terminal device and further determine which part of the marked portion needs to be noted.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and a purpose thereof is that even a novice who has no knowledge of the assembling work in each process can simply mark one place in a drawing displayed on a screen and perform each process. An object of the present invention is to provide a work instruction display system capable of displaying a drawing on which fine markings are made according to the process.

[0010]

In order to solve the above-mentioned problems, a work instruction display system according to the present invention provides a work line in a production line in which various works flowing on a line are sequentially processed and commercialized. A work instruction request from each terminal installed in the work place, a system configured so that work instruction data corresponding to each terminal from the main control unit is transmitted, the operator,
Editing control for performing marking for clarifying the component arrangement on a drawing of one work displayed on a screen by inputting a mark at one place common to each process in the drawing of the work. A first storage unit for storing, as work instruction data, a drawing of one work edited by the editing control unit and corresponding marking data for each work, and a part item for each process. A second storage unit that previously stores a marking table in which data such as the presence / absence of marking, the color of marking, and the displacement of coordinate transformation for indicating the marking position are stored in advance, and the work place of each process at the work site In response to a readout instruction from each terminal installed in the second storage unit, a marking table to be displayed in its own process among the marking tables stored in the second storage unit. A third storage unit for reading and storing the table, and in response to a work instruction request from each of the terminals, reads the work instruction data stored in the first storage unit and stores the work instruction data in the third storage unit. A terminal control unit for controlling the display unit to display the drawing data and the marking for each work required for each process on the display unit with reference to the marking table.

[0011]

In the editing control unit, the operator performs an input for marking on one place common to each process in the drawing of one work displayed on the screen, thereby arranging the parts in the drawing of the work. Marking is performed for clarity, and this is stored in the first storage unit as work instruction data for each work.

The second storage unit stores marking data such as the presence / absence of marking, the color of marking, and the displacement of coordinate transformation for designating the marking position for the component item for each process. The table is stored in advance.

[0013] With this, when the terminal installed in the work place of each process in the work site is started up, the terminal control unit operates the second control unit.
Of the marking tables stored in the storage unit, the marking table to be displayed in its own process is read and stored in the third storage unit. Thereafter, in the terminal control unit, among the work instruction data (drawing data and marking data) read from the first storage unit, the drawing data of the corresponding work is displayed on the display unit, and the third storage unit With reference to the marking table stored in the storage unit, a marking according to the own process is performed, and this is displayed on the display unit.

Therefore, an operator who is in charge of each process is required to provide the processing data (specifically, the design drawing and the processing performed on the design drawing) displayed on the terminal provided at the work place of each process. The workpiece flowing on the line is processed according to the processing data while watching the marking.

[0015]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an electrical configuration of a work instruction display system according to the present invention.

This system is roughly divided into an editing machine A for reading design drawings and processing the read design drawings.
, A host computer B for transmitting and receiving data to and from the editing machine A, and terminals C1, C2,... For receiving data from the host computer B. It is configured to be bidirectionally connected by a communication line such as 232C.

The output of a reading device 11 provided with a scanner for reading a design drawing (specifically, a work drawing),
An output of the input unit 12 for marking one necessary portion of the read work drawing is guided to an editing control unit 13 for controlling the operation of each unit of the editing machine A. And the file creation unit 15 are bidirectionally connected.

The edit control unit 13 controls the creation of work instruction data by associating a work drawing read by the reading device 11 with a marking attached to a required part of the work drawing according to an instruction from the input unit 12. At the same time, it sends and receives data to and from the main control unit 21 of the host computer B.

The file creating section 15 is a block for creating a file by giving a file name to the work instruction data for each edited work.

The editing control unit 13 and the first storage unit 16
Is a bidirectional connection, and the first storage unit 16
Is configured to store the work instruction data to which a file name is assigned in the file creation unit 15 for each type of work flowing on the line.

The output of the edit control unit 13 is transmitted to the display unit 1
4 The display unit 14 displays an editing operation, and displays a work drawing read by the reading device 11, a marking applied to a necessary portion of the work drawing, and the like.

Further, the editing control unit 13 and the main control unit 21 of the host computer B have a bidirectional connection, and the main control unit 21 and the second storage unit 22 have a bidirectional connection. ing.

The second storage unit 22 stores a marking table in which data such as presence / absence of marking, marking color, displacement of coordinate transformation for designating a marking position, etc. is stored for the component item for each process. Is stored in advance.

The output of the main control unit 21 is guided to a display unit 23, and the marking table stored in the second storage unit 22 is displayed as appropriate.

Further, the main control unit 21 and the terminal control units 31 of the terminals C1, C2,. .

Each of the terminals C1, C2,... Has the same configuration, and as shown in the terminal C1, the terminal control unit 31, the operation unit 32, the 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.

The third storage unit 33 stores only the transferred marking table necessary for its own process among the marking tables stored in the second storage unit 22 when the terminal is started up. Remember.

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. With reference to the marking table, a marking suitable for each process is displayed together.

FIG. 5 shows a part of the marking table stored in the second storage unit 22.

That is, in this marking table, each process (ceiling process, floor process,...) In the horizontal direction, and each work (sanitary, stair, entrance, etc.) which is a component item (hereinafter referred to as a marking item) in the vertical direction. ..) are arranged in a grid pattern, and data indicating a display color and coordinate data indicating a displacement are written in corresponding locations. The menu of the marking items can be freely changed on the user side. In this embodiment, the marking color in the ceiling process is red for sanitary, the stairs are blue, the entrance is absent (indicated by x), and the marking color in the floor process is blue for sanitary, yellow for the stairs, and red for the entrance. In addition, sanitary is (a1, b1) (a2, b2) as the displacement in the ceiling process, (c1, d1) (c2, d2) in the stairs, no entrance (shown by x), and sanitary as the displacement in the floor process. Is (a
3, b3) (a4, b4), the steps are (c3, d3) (c
4, d4) and the entrance is (e3, f3) (e4, f4).

However, the display color of each marking item in each process is arbitrary, and is not limited to the above-mentioned three colors of red, blue and yellow. Further, the reason why the color is changed for each marking item is that it is very difficult to determine which member is which unless the color is changed on the display screen.

FIG. 6 shows a marking table transferred to and stored in the third storage section 33 of each of the terminals C1, C2,. That is, the terminal (for example, C1) installed in the ceiling process stores the marking table shown in FIG. 5A, and the terminal (for example, C2) installed in the floor process stores (b) in FIG. Will be stored. That is, only the tables necessary for each process are transferred and stored.

Therefore, the terminal C1 installed in the ceiling process refers to the marking table shown in FIG. 6A stored in the third storage unit 33, and if the marking item is sanitary, it is displayed in red. The marking is displayed on the display unit 34 by adding the displacement to the marking coordinates.

Next, the operation of the work instruction display system having the above-described configuration will be described with reference to the flowchart of FIG. 2 and the coordinate conversion diagrams of FIGS. 3 and 4.

FIG. 2 shows each terminal C1, C2,.
3 is a diagram showing a display screen of the display unit 14 of the editing machine A, and FIG. 4 is a diagram showing a display screen of the display unit 34 of the terminal device C1.

First, the operator reads each work drawing (processing data) flowing on the production line by the reading device 11.

In the reading process, when it is necessary to call attention to a required part of each work drawing displayed on the display unit 14, the input unit 12 is operated to select a marking item. And marking at the corresponding position.

Here, the display section 14 displays a sanitary work drawing (plan view) as shown in FIG. 3, for example, and the operator can display the entire sanitary bathtub portion displayed on the display section 14. Mark to include. The marking coordinates at this time are (x1, y1) (x2, y
2).

The sanitary work drawing and the marking data (coordinate data) created in this manner are sequentially stored in the first storage unit 16 after the file name is given in the file creation unit 15. That is, the first storage unit 16 stores the sanitary work drawing and the marking data as one work instruction data.

The operator marks all the work drawings in this way, assigns a file name to the drawing, and stores the file name in the first storage unit 16.

Thus, the data input before the start of the operation is completed.

Thereafter, when the production line operates and there is a request for a work start instruction from each terminal installed at the work place in each process, the host computer B stores a marking table corresponding to each terminal in the first place. 2 is read from the storage unit 22 and transmitted.

This transmission operation will be described for the terminal C1 installed in the ceiling process.

The terminal C1 selects a marking table of its own process from among the marking tables shown in FIG. 5 stored in the second storage unit 22 at the time of startup, and stores the selected marking table in the third table. Storage unit 3
3 (step S11). Here, the terminal device C1
Since is a terminal installed in the ceiling process, the third storage unit 33 stores the marking table shown in FIG.

In the terminal C1 in which the marking table of its own process is stored in the third storage unit 33 as described above, the field operator then turns on the "necessary" button of the operation unit 32 (step S12), this ON signal is given to the main controller 21 of the host computer B.

In response to the ON signal, the main control unit 21 reads out the corresponding work instruction data from the work instruction data stored in the first storage unit 16 of the editing machine A, and transmits this to the terminal control unit 31. (Step S13).

The terminal control section 31 displays the work drawing included in the transmitted work instruction data on the display section 34 (step S14). At this time, the display unit 34 displays FIG.
It is assumed that the sanitary work drawing shown in FIG.

In the terminal control section 31, the third storage section 3
3 is referred to (step S15). Since the marking item at this time is sanitary, the terminal control unit 31 determines the marking coordinates (a1, b1) (a2, b2) included in the work instruction data based on the displacement (a1, b1) (a2, b2) of the coordinate conversion given to the sanitary. x1, y
1) (x1, y2) with displacement added (x1 + a1,
y1 + b1) (x2 + a2, y2 + b2) are calculated (step S16), and the work drawing displayed on the display unit 34 is marked and displayed according to the calculated marking coordinates (step S17). The marking portion at this time is a partition portion including the door shown in FIG.

That is, the displacement (a1, b1) (a2, b2) of the coordinate transformation read from the third storage unit 33 converts the marking position included in the work instruction data into a partition part. Value.

In the ceiling process, when a work with sanitary comes, it is necessary to attach a wooden bar for reinforcement to the door, but the marking display as shown in FIG. It is possible to easily recognize a portion requiring attention in the own process.

Although not shown, the drain port is sanitarily drilled in the flooring process, so that the display portion 34 of the terminal C2 installed in the flooring process has a marking on the drain port portion. Will be displayed.

That is, the displacement (a3, b3) (a4, b4) of the coordinate conversion read from the third storage unit 33 converts the marking position included in the work instruction data into a drain port portion. It has a value like this.

That is, for the operator who performs such a marking, when the sanitary work drawing is displayed on the display unit 14 of the editing machine A, which part of the sanitary should be marked depending on the process. It is only necessary to mark the entire sanitary without making any judgment. In this way, simply by marking the entire sanitary, the terminal C installed in the ceiling process
In 1, the marking is displayed on the partition including the door as shown in FIG. 4, and the terminal C2 installed in the floor process displays the marking on the drain port,
Fine marking can be performed for each process.

When the necessary drawing and the marking are displayed on the display unit 34 in this way, the terminal C1 is in a standby state for the next button operation by the field worker (step S1).
8).

[0057]

According to the work instruction display system of the present invention, at the time of marking work by an operator, only marking is performed on one part of the work drawing displayed on the screen, and the terminal device of each process uses a texture according to the process. Since the configuration is such that fine markings are displayed, the following various effects can be obtained. (1) Even beginners who have no knowledge of the assembly work in each process can perform marking. (2) Since there is no need to slightly shift the marking position for each process, the number of markings by the operator is reduced, and workability is improved. (3) Since it is not necessary to have information for each process and for each unit, the burden on the main control unit is reduced. (4) Since a work drawing in which a portion requiring attention in each process is marked on the terminal is displayed, a work error or the like can be avoided, and quality can be improved.
