The gist of the invention as set forth in claim 2 is that the notification means includes a comparison means for comparing the data of the color currently being painted by the painting robot with the production data, and a comparison means for comparing the data of the color currently being painted by the painting robot with the production date. 2. An operating state display device for a painting robot according to claim 1, further comprising display control means for displaying coincidence or mismatch of data.

"Operation" In claim 1, the color to be displayed is stored in the storage means in correspondence with the color of the paint. The corresponding color is selected from the storage means by the display control means based on the coloring data supplied from the production data, and is selected and displayed.

In the invention as set forth in claim 2, the comparison means compares the data of the color currently being painted by the painting robot and the production data. The match or mismatch between the two data based on the comparison result of the comparison means is displayed by the display control means.

"Example" Hereinafter, an example of the present invention will be described in detail with reference to the drawings. However, unless there is a specific description, the dimensions, materials, shapes, and relative arrangements of the supplied parts described in this example are not intended to limit the scope of the present invention. Not a real thing, just an illustrative example! Not too harsh.

First, the supply of a painting device equipped with an operating state display device for a painting robot (hereinafter simply referred to as an "operating state display device") according to this embodiment will be explained with reference to FIGS. 1 to 3. . FIG. 1 is a supply diagram of a coating apparatus using an operating status display device, and FIG. 2 is a diagram showing the coating status of each coating robot 4 displayed on the display 24.

The computer main body 2 receives and receives production data from the host computer 1, and if there are any changes or additions, the computer main body 2 corrects the data. Thereafter, the computer main body 2 transmits production data to one or more robot controllers 3 via the communication cable 5. The robot controller 3 operates the painting robot 4 based on the production data.

The computer main body 2 monitors the painting line while the painting robot 4 is in operation. At this time, the computer main body 2 reads the paint color coat currently being used from the robot controller 3, and displays it on the display 24'' along with other information as shown in the screen display example of FIG. In the figure, numeral 11 is a painting robot display section, numeral 12 is a painting robot operating state display section, numeral 13 is a workpiece display section, and numeral I is
4 is a conveyor display section. Furthermore, the current paint color is displayed as one of the display items for the operating state of the painting robot 4 (for example, in the diagonally shaded area in the painting robot operating state display section 12, etc.).

FIG. 3 is a block diagram functionally expressing the /stem in FIG. 1. The production data from the host computer 2t (symbol 1 in FIG.
(2) and written into the production data RAM 26. Here, if there are any changes or additions to the production data, the corrections can be made manually using the keyboard 25 and through the keyboard Natsu/F3]. After that, the corrected production data is transferred to the robot controller 1/F.
29 to the robot controller 23 (3). At this time, the production data stored in the production data RA, M26 is not deleted but is retained.

While the painting robot 4 (not shown in FIG. 3) is in operation, the CPU 22 reads the paint color code used by the painting robot 4 from the robot controller 23 through the robot controller I/F 29. Further, it is compared with the production data RAM 26, and if they are the same, the color data to be displayed on the screen is searched from the paint color/display color correspondence table RAM 27. Then display! /F
30 and is displayed on the display 24 by color rather than by color code. If robot controller 2
If there is a difference between the coating color code read from 3 and the production data, it is assumed that workpiece misalignment may have occurred, and the CPU 22 informs the operator of the coating equipment of the problem through the display I/F 30 and the display 24. Let me know.

Next, the operation of the operating state display device according to this embodiment is illustrated in FIG.
This will be explained using a PAD diagram of playback operation.

As shown in Figure 4, before the full °C operation, the RAM 27 for the paint color/display color correspondence table is created (S2), and color data is created to make the display color the same as the actual paint color (S3). You must prepare accordingly. When creating this color data,
Display a palette of colors on the screen and let them choose.
It is also possible to shorten the setting time.

Changes and additions to production data may be made even when the painting robot 4 is in operation (S4 to S5).

Regarding the correspondence between paint colors and display colors, other than the table format, it may be replaced with a method that allows a one-to-one correspondence.

After each setting is completed, the production data is transferred to the robot controller 3 (S6).

While the coating equipment is in operation, the process continues until the production data received from the host computer is exhausted (S7).

Read the paint color code from the controller 23 (S8
), the paint color code is compared with the production data in the computer main body 2 (S9), and compared with the RAM 27 for the paint color display color correspondence table (Sz), and the color data corresponding to As is used to determine the color of the paint color. Display color on 24 (
