Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coating apparatus that automatically performs coating on objects to be coated, such as automobile bodies, household products, etc., based on preset coating data.

Conventionally, in order to automatically paint objects such as automobile bodies, a coating machine operated by an operating device is installed at the painting site.
A conveyor is provided for conveying the object to be coated by the coating machine, and in order to automatically apply the coating to the object to be coated by the conveyor, the coating data stored in advance is used. A coating apparatus] 1 is known in which a control device i1 for controlling the actuating device f is provided at a position away from the painting site.

The control device includes drive data for driving a registration locator to move the coating machine up and down according to the shape of the object to be coated, and paint color data for operating a color change valve to control the color of the paint. Various painting data such as paint film data for controlling the thickness of the paint film by adjusting the paint discharge valve are stored as a predetermined program, and furthermore, a control program for executing the program is stored, The coating machine is operated based on each of these grograms VC, and the coating machine is automatically coated on objects to be coated that are sent by a conveyor.

By the way, when performing painting work using such programs and control-based painting equipment sounds, if part of the shape of the object to be painted is changed, it is necessary to change or modify the drive data, paint color data, etc. described above. This is often the case.

In this case, the work of changing coating data according to the prior art was carried out by the following procedure. After taking into account the change conditions, a rough total of change data is calculated by desk calculation, and this change data is input into the control device as new painting data. Next, a program is executed based on this earthquake disaster data, and test coating is performed while the object to be coated is transported on a conveyor. During this test coating, the operational status of the coating machine, the elapsed time, the discharge status of the thread, the orientation of the coating machine, etc. are visually observed, and the results of this observation are recorded in a notebook or the like. Next, a control device installed at a location away from the painting site corrects the painting data based on the data recorded as described above while remembering the test painting situation. Furthermore, based on the newly corrected coating data, all test coatings similar to those described above are carried out, and the coating data is corrected again. In this way,
We repeatedly performed test coatings and changed coating data.
Finally, determine the painting data for the painting work.

However, in the method of changing the m-mounting data according to the prior art described above, first, all the bookkeeping is performed while visually observing the test coating situation at the painting site, and the bookkeeping results are inputted from the painting site to the controller inside the converter room. This has the drawback that the data modification process takes a long time, as the user has to go back and perform all the input work. Second, since the data entered in the notebook is entered while remembering the test painting situation, there is a drawback that the actual situation becomes unclear. Thirdly, as a result of the second drawback, the number of test coatings increases in order to properly correct the coating data. It was developed in view of the above, and its feature is that the painting equipment is equipped with an auxiliary setting device at the painting site that can change the painting data at the painting site and input this changed data to the control device as new painting data. This is what we provide.

It has an address key 40 for inputting the address of the displacement point to be changed, and a step key 41 for moving the address input to the address key 40 to the plus side or minus side one by one. By operating it, the lamp 42 at the position corresponding to the address lights up.The auxiliary setting device 20 also has a data key 43 for inputting change data on the change data display screen 37, and a data key 43 for inputting change data on the change data display screen 38, and a data key 43 for inputting change data on the change data display screen 38. Displayed as increase/decrease (10
) is provided with an increase/decrease key 44. Furthermore, a changeover switch 45 is provided at the lower right of the figure to switch between a write mode and a monitor mode, and by switching the changeover switch 45 to the monitor mode side, the address key 40 or Stezzo key 41 and the data key 43 or increase/decrease By operating the key 44, each data can be set, stored, and displayed, and by switching to the write mode side, the set f update data is stored in the main memory 22 of the control device 22 as new paint data. can be entered.

The coating device of the present invention is configured as described above, but now,
The driving data for the vertical reciprocator of the Totsurushi locator 5 as painting data is shown in the painting data display cloth 3 in Fig. 4.
Assume that the data is as shown in 6. In other words, the reason why the coating data is "14" at the star I position [(ORG) when the switch 17 is activated is that the coating data is "14" as shown in FIG.
6 indicates that the height H0 decreases from the height Ho to Hl4, and the height HA at the distance LA = 070 (cm) indicates that the height HA rises from Hl4 (11) to Hl2, and the displacement point A. In B, it is shown that the height HB rises from Hl2 to HIO at a distance L8=090 (cIrL). Similarly, at the displacement point ■, the distance LH=420 (crIL
) indicates that the height Hl decreases from Hll to Hl3, and finally the final position (g
ND') shows that the paint sprayer 16 rises to the upper end position # of H6. Then, based on the above-mentioned drive data, the coating machine 16 moves along the trajectory shown by the fifth solid broken line.

However, when the transport conveyor 1 is moved in the direction of arrow A to execute the program based on the drive data described above, the carriage 3
When the upper car body 4 is transported and the switch 17 is activated, test painting starts, and the control device 22 outputs a signal instructing the motor 11 of the vertical reciprocator to rotate downward, and the coating machine at the height HoK 16 is lowered together with the moving frame 12 to the position H14. At this time, the motor 15 of the horizontal reciprocator also rotates, and the sprayer 16 reciprocates in the direction of arrow C. Then, truck 3 traveled 70 cFrL (1
2) At the displacement point A, the coating machine 16, which was at the height Hl4, rises to H1□. Thereafter, the sprayer 16 moves in the same manner along the solid broken line in FIG. The upward rotation of stops. During this time,
The coating machine 16 executes a coating program based on the received coating data such as coating film data and coating color data, and applies test coating to the automobile body 4.

When the shape of the automobile body 4 is changed, it is necessary to change the drive data for the vertical registration locator described above. In this case, the changed data is determined by the following procedure.

First, drive data is calculated by desk calculation in consideration of the change conditions, and is input as new data to the main storage device 24 by the setting device 30.

Next, a nologram is executed based on the drive data manually inputted in this way, and the conveyor 1 is moved to perform test coating. At this time, the operator uses the auxiliary setting device 20 at the painting site to set the change data in the setting device 20.

(13) Furthermore, the changed data is input to the control device 22 as new data, and test painting is repeated again to obtain optimal drive data.

Here, the method of setting changed data according to the above procedure will be specifically described with reference to FIG. First, select a predetermined program using the program selection key 39, display the theoretically calculated data as shown in FIG. 45 to monitor mode.

When the program is executed in this state, the car body 4 is conveyed by the conveyor. The worker is painting machine 1
While visually checking the movement of 40.6, select the change data that is expected to result in a good painting job using the address key 40.6. Input is made using the STEP key 41, data key 43, and increase/decrease key 44. That is, the expected change data is indicated by the dashed-dotted line E in FIG.
Assume that it is as shown in

Now, it is necessary to change the descending height of the paint sprayer 16 from Hl4 to Hts at star i position (ORG) (1
4) If the address key 40 is operated as r201J, the lamp 42 at that position will light up, so if the data key 43 is subsequently operated as "16", Hlg will be displayed at the corresponding address position on the changed data display section 37. is input. At this time, if the increase/decrease key 44 is operated as "+2" instead of the data key 43, H and 6 can be entered on the increase/decrease data display screen 38, but if inputted using either of the keys 43 and 44, Enough. When performing the above input operation, paint sprayer 1
Since the current height of 6 is displayed on the height display screen 33,
Easy to change.

Next, if you want to change the height HA from HI3 to HI3 at the displacement point A which has progressed the distance LA=70c+a, move the address key 40 to r202J or step key 41 to "+" to change the height HA to the corresponding position. Since the runno 42 lights up, input change data or increase/decrease data in the same way as described above. At this time, there is no need to change the distance LA, so it can be left as is.

Hereinafter, change data is entered while visually checking the paint sprayer 16. Since it is necessary to change only the distance L1 at the displacement point, the address key 40 is operated to "217" and the data key 43 is set to r400j. Operation or increase/decrease key 44
is operated on the r-20J and the change data is input into the display screen 37 and the display screen 38.

The expected vertical movement of the sprayer 16 is set in the auxiliary setting device 20 by the above operation, so by switching the changeover switch 45 to the write mode, the changed data is stored in the main memory 20 as new vertical reciprocator drive data. is input. Then, the above-described test coating can be repeated again based on the new drive data.

As described above, in the coating apparatus of the present invention, during test coating, the operator can modify the coating data using the auxiliary setting device 20 while visually observing the coating situation at the coating site, and can change the newly set changed data by switching the mode. Since the data can be input to the control device, not only can changes in coating data be made more accurate, but also the number of test coatings can be reduced. Further, since there is no need to go back and forth between the painting site and the control device 22, the working time can be shortened, and since the auxiliary setting device 20 is portable, it can be carried to the painting site as needed.

In the above-described embodiment, the auxiliary setting device 20 was described as being used for correcting the vertical reciprocator drive data of the top reciprocator 5, but the present invention is not limited to this.
Paint color data that activates the color change valve, paint film data that activates the paint discharge valve, oscillation data that performs the oscillation side 1 of the coating gun or rotary atomizing head of the atomizer 16, and even the side reciprocator. Of course, if the data is available, the drive data of the side reciprocator can be used for various painting data correction work. Further, the coating machine 16 is not limited to an electrostatic coating machine, but may be an air gun coating machine. moreover,
The display surface of the auxiliary setting device 20 is not limited to that shown in the figure.
It is possible to display the format corresponding to the program, and it was also mentioned that the address key 40 and step key 41 are used in combination, and the data key 43 and increase/decrease key 44 are used in combination (17), but only one type of these can be used. You can also use only moreover,
The object to be coated is not limited to the automobile body 4, but may also be furniture, home appliances, etc. In this case, it goes without saying that the painting site may be located near the painting booth.

Since the coating apparatus according to the present invention has been described in detail above, it achieves the following effects.

(2) Since the auxiliary setting device allows the coating data to be changed at the painting site, the f-change data can be set accurately and the number of test coatings can be reduced.

■ Since the change data set with the auxiliary setting device can be input directly to the control device from the heavy equipment site, there is no need to go back and forth between the painting site and the control device, reducing work time.

■ By providing a coating data display screen on the auxiliary setting device, it is possible to enter changed data while comparing it with the coating data stored in the control device, and also to input new data on the changed data display screen. Since changed data can also be displayed, (18) it is possible to change data while facing the object to be coated without relying on memory.
