[Detailed description of the invention]

[0001]

The present invention is intended to correct the data of coating conditions from the side of a coating booth in which a coating gun is installed, and to store the corrected data in place of the original data. The present invention relates to a coating condition management device for an automatic coating system.

[0002]

2. Description of the Related Art A conventional example of a coating condition management apparatus will be described with reference to FIGS. 1 and 2 showing an embodiment of the present invention.

In FIG. 2, reference numeral 1 denotes a transport line for suspending and transporting an object to be coated in the direction of the arrow. 2
The first and second coating guns 5 and 6 installed in the coating booths 3 and 4 respectively perform automatic coating sequentially. At this time, when the type of the object to be coated is changed due to a change of a lot or the like, the coating conditions such as the amount of paint discharged from each of the coating guns 5 and 6, the atomizing air pressure and the pattern air pressure are appropriately changed. Therefore, the management is performed in the management booth 8.

In the management booth 8, a coating condition setting device 10 is provided, and a data storage unit 11 connected thereto is provided.
In addition, data of coating conditions suitable for each type of the object to be coated in each of the coating guns 5 and 6 is stored in advance together with an identification number indicating the type of the object to be coated. Then, when the type of the object to be coated is changed, the type number of the object to be coated is input by the designation unit 12. Setting device 10
, And a control signal is sent to the coating condition control devices 13 and 14 of the respective coating guns 5 and 6 so that the respective coating guns 5 and 6 are controlled to predetermined coating conditions.

[0005]

Incidentally, the coating conditions of the coating guns 5 and 6 may need to be modified depending on the atmospheric conditions and the like when actually performing the coating. The setting device 10 is provided with a correction operation unit, and measures are taken to correct the called coating condition data and to transmit a corresponding control signal.

However, in such conventional means,
It is necessary to go to the management booth 8 to correct the coating conditions after checking the coating condition of the object at the coating booths 3 and 4, and return to the coating booths 3 and 4 again to check the coating condition. It was not only troublesome, but also inefficient when stopping the line.

Further, even if the optimum coating conditions can be set on the same day by the correction, the correction data disappears when the lot is changed and another coating condition is called, and when the object to be coated with the same lot comes next. Therefore, there is no reproducibility, so it is necessary to write down the correction data in a memo etc. and to correct the data again when the same lot comes in.If you forget to write down, the above correction work will be started from the beginning There was a drawback that had to be reworked.

SUMMARY OF THE INVENTION A coating condition management apparatus for an automatic coating system according to the present invention has been devised in view of the above points, and is called by a condition setting means at the installation position of a coating gun. And a conversion storage unit for storing the corrected data in place of the corresponding original data in the data storage unit.

[0009]

When the type of the object to be coated is changed, the operator inputs the type number, calls the coating condition data corresponding to the condition setting means, and moves to the installation position of the coating gun. There, automatic painting is performed according to the called painting conditions, and the painting condition is checked.

In the case where the coating condition is not correct and the coating conditions are corrected, the data called directly by the condition setting means from the correction means provided at the gun installation position is corrected. Next, automatic coating is performed based on the correction data, and the check is performed again. If further correction is necessary, the same correction as above is performed.

If it is determined that the finish is good, the conversion storage means at the gun installation position is operated. Then,
With respect to the coating of the lot, the automatic coating is continued with the final correction data, and the final correction data is stored in place of the original data corresponding to the same identification number in the data storage unit.

When the type of the object to be coated is changed and data of another coating condition is called, the correction data disappears. However, since the correction data is newly stored in the data storage unit as described above, the same type is next stored. If the type number is input when the object to be coated arrives, the correction data is called, and automatic coating is performed under the optimum coating conditions from the beginning.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In the present embodiment, the first and second coating booths 3 and 4 are provided with a first correction unit 21 and a second correction unit 22 respectively.
Is connected to the coating condition setting device 10 of the management booth 8. Each of the correction units 21 and 22 can correct the data of the coating condition called from the data storage unit 11 to the coating condition setting device 10.

Each of the correction units 21 and 22 has a conversion storage unit 2
3 and 24 are provided, and the conversion storage units 23 and 24 are
When N, the coating condition data corrected by the correction units 21 and 22 can be stored in place of the corresponding original data in the data storage unit 11.

Next, the operation of this embodiment will be described. When the type of the object to be coated is changed, the operator inputs the type number from the specifying unit 12, calls the data of the coating condition corresponding to the coating condition setting device 10, and moves to the first coating booth 3.

The procedure of the work in the first painting booth 3 is shown in FIG.
A control signal corresponding to the called coating condition data is sent to the first coating condition control device 13 so that the first coating gun 5 has a predetermined coating condition. The automatic coating is performed on the object under the control. When the painting is completed, the worker checks the painting condition.

When it is necessary to correct the coating conditions because the coating condition is not good, the operation is called by the coating condition setting device 10 by the operation of the first correction unit 21 provided in the first coating booth 3. Correct the data. Then, the automatic coating is performed next based on the correction data, and it is checked again. If further correction is necessary, the correction is performed in the same manner as described above.

If it is determined that the finish is good, the conversion storage unit 2
Turn 3 ON. Then, the final correction data is
The data is replaced with the original data corresponding to the same identification number in the data storage unit 11 and stored. Then, for the coating of the lot, automatic coating is continued according to the final correction data described above.

In the second painting booth 4, if there are no other workers, the same check and check are performed in parallel with the first painting booth 3.
It is sufficient to perform the work such as correction, and if there is only one worker,
It may be performed after the first painting booth 3 is over.

When the type of the object to be coated is changed and data of another coating condition is called to the coating condition setting device 10, the correction data obtained by the above-mentioned operation disappears, but the correction data is stored in the data storage unit. 11 is newly stored in association with the identification number of the object to be coated, so that the next time the same type of object to be coated is painted, the type number is input from the designation unit 12 so that
The correction data is called by the coating condition setting device 10,
Automatic coating is performed from the beginning under optimal coating conditions.

In the above embodiment, the case where there are two painting booths each having a painting gun is exemplified. However, the case where only one painting booth or three or more painting booths can be similarly applied.
