.

Next, the operation of the painting system having the above configuration will be explained.

In order to coat an object to be coated, such as the body of an automobile, in the coating device 4, the paint stored in the mixing tank 1 can be pumped to the coating device 4 using the pump 6. When the remaining amount of paint in the mixing tank 1 decreases, paint can be replenished into the mixing tank 1 from the drum can 3 by the pump 1O.

To grasp the remaining amount of paint in each mixing tank 1, air is sent at a constant flow rate from the air supply source 17 to the mixing tank l via the air supply vibrator 13, and the air is blown into the paint from the tip of the air supply pipe 1. In this case, the pressure inside the air supply pipe 13 can be measured by using the pressure sensor 18.

That is, when there is a large amount of paint remaining in the mixing tank 1, the hydraulic pressure acting on the tip of the air supply pipe 11 increases, and when there is little paint remaining, the hydraulic pressure acting on the tip of the air supply vibrator 11 increases. Therefore, if the flow rate of air sent from the air supply source 17 is constant, the pressure inside the air supply pipe 13 will vary depending on the remaining amount of paint. Therefore, by measuring the pressure inside the air supply pipe 13 with the pressure sensor 18, the amount of paint remaining in the mixing tank I can be measured. Also, drum can 2
Regarding the remaining amount of paint, the remaining amount of paint can be determined by measuring the pressure of the air supply pipe I5 with the pressure sensor 19 as in the case of the mixing tank 1.

The computer 2I calculates and stores the amount of paint remaining in the mixing tank and the amount of paint remaining in the drum 2 based on the pressure measurement results of the pressure sensors 18, . . . , 19. computer 2
1 stores this information on a CRT as shown in FIG.
22.

In this example, there are a number of mixing tanks numbered up to number 42 (the one in the upper row of tanks in the upper and lower rows of tanks labeled with each number in Figure 3) and a number of drums (the one in the upper row in Figure 3). (The one in the bottom row of the top and bottom two rows of tanks with each number)
The display is for a coating system equipped with

In Figure 3, Not , 7, 8, 9.12 131
4. The mixing tanks and drums shown at 15, 18, 19, 37, 39, and 42 are empty and are not used for painting, so they are in a rest state. On the other hand, No.2.3.4.5.6.1011.16,17
,20,21.22 33 34 3536.37.3
B, 39, 40, 41, and 42 indicate the state in which the paint is stored, and the remaining amount is indicated by the height of the bar graph of the blacked out part. The bar graph of the bipartite bone filled in black in FIG.

In the storage device of the computer 21, preferred upper and lower limits are set for the remaining amount of paint in the mixing tank 1 in order to pump the paint in good condition when the paint is pumped to the coating device 4 using the pump 6. An abnormal upper limit value is set slightly above the lower limit value, and an abnormal lower limit value is set slightly below the lower limit value. Similarly, in the drum can 2, a lower limit value for replenishment is set regarding the remaining amount of paint. Then, the computer 21 displays on the CRT 22 the amount of paint remaining in the mixing tank L in green on the screen between the upper limit and the lower limit, and between the abnormal lower limit and the lower limit, and between the upper limit and the abnormal upper limit. Values between the values are displayed in yellow, and values below the abnormal lower limit or above the abnormal upper limit are displayed in red. Further, when the remaining amount of paint in the drum 2 is equal to or greater than the lower replenishment limit value, it is displayed in green, and when it is less than the lower replenishment limit value, it is displayed in red.

Therefore, the operator can easily identify the mixing tank 1 or drum 2 when an abnormality has occurred by simply identifying the color of the bar graph on the screen of the CRT 22.

On the other hand, the speech synthesis table shown in FIG. 4 is stored in the storage device built into the speech synthesis unit 23. In the table shown in FIG. 4, code columns from column 1 to column 2 are formed, and a voice code as shown in FIG. 4 is recorded in each code column.

Then, based on the occurrence of an abnormality in the amount of paint remaining, the computer 2
Based on the instructions from 1, the speech synthesis unit selects the corresponding speech codes from the 1st column to 2nd column of the speech synthesis table in the storage device, synthesizes the selected speech codes in numerical order from the 1st column to 2nd column, The contents are uttered by the speaker 24.

In this way, the worker can be alerted to the occurrence of an abnormality using the sound from the speaker 24, so that the worker can be sure to check the specific mixing tank.
Alternatively, an abnormality in the amount of paint remaining in a particular drum can 2 can be known, and countermeasures can be taken quickly.

In addition, in the speech synthesis table shown in FIG.
Since there are blank areas in each of columns 11 to 2, the types of audio warnings issued by the speaker 24 can be increased by storing other information in these blank areas. That is, if the warning content is newly recorded as a voice code in the necessary blank space of each code column in the voice synthesis table shown in Figure 4, the number of mixing tanks 1 or drums 2 will increase. In addition to being able to easily respond to problems, it is also possible to appropriately issue instructions for more complex responses.

"Effects of the Invention" As explained above, the present invention can be applied to a plurality of paint supply sources or a plurality of paint replenishment sources when the remaining amount of paint in a specific paint supply source or a specific paint replenishment source becomes abnormal. , the computer issues a command to the voice synthesis unit, selects the appropriate coat from the voice code of the voice synthesis unit, and the voice synthesis unit issues an alarm from the speaker to warn about the specific supply source or paint supply source where the abnormality has occurred. Ru. This allows the operator to easily identify which of the multiple paint supply sources or multiple paint replenishment sources is experiencing an abnormality, and quickly respond to abnormalities in the amount of paint remaining. .

In addition, the warning content of an abnormality is selected and synthesized as appropriate from multiple code fields in the voice synthesis table recorded in the voice synthesis unit and transmitted to the speaker, so even if there are many paint supply sources and paint supply sources, Appropriate warnings are provided regarding the specific paint source and paint supply source that has experienced an abnormality.
