The lever 124, to which the 23 is attached and which contacts the striker 123, also contacts the limit switch 125. 12
6 indicates a guide rail.

The operation of the above embodiment will be described below. The trolley 10 which supports the object 55 to be processed receives the power of the endless rotary body 41 due to the passive projection 47 thereof engaging the pusher body 44. As a result, the trolley 10 enters, for example, the coating work unit 60, and while traveling in the coating work unit 60, the desired painting work is performed on the workpiece 55 by the coating device, and then the coating work unit 60 is performed.
Go out of 60. Next, the carriage 10 enters the drying work section 61,
An object to be processed is dried by a drying device while traveling in the drying work section 61.
The desired drying process for 55 is performed, and then the drying operation unit 61 is exited. During the painting work and the drying work, the suction force on the suction passage 4 side acts on the porous floor plate 3, whereby the atomized paint generated in the coating chamber and the dust generated in the drying chamber are sucked and removed.

The trolley 10 cyclically moves on the moving path 56, and various processing operations are performed on the object 55 to be processed as described above. Then, the objects 55 to be processed are wholesaled from above the dolly 10 and new objects 55 to be processed are loaded on the empty dolly 10.

Periodically, for example, every month, the empty carriage 10 is branched into the cleaning movement path 56a. Then, as shown by an imaginary line A in FIG. 1, the carriage 10 is fed onto the rotary rail 67 of the reversing device 62 via the trolley device 12 by a feeding device or manually. Next, the rotary rail 67 is rotated 180 degrees about the horizontal axis 69, and the top and bottom of the carriage 10 is changed with the support device 11 facing downward as shown by a virtual line B in FIG. In this state, the moving body transport device 64 is moved to the inlet portion 73 side, and its support rail 91 is connected to the rotary rail 67. Then, in a state where the movable force cover 94 is opened, the carriage 10 supported by the rotating rail 67 is transferred to the support rail 91 by a feeding device or manually and brought to a state shown by a solid line C in FIG. Cover 94
To close the slit 93.

Then, it is moved on a fixed path 79 and stopped at an intermediate portion as shown by a virtual line D in FIG. At this time, the supporting device 11 is opposed to the cleaning device 65 and stopped as shown in FIGS. In this state, the high pressure water 106 is jetted from each nozzle 105 toward the support device 11. As a result, paint or dust that adheres to the receiver 32A, the receiving pin 32B, the frame 33, and the like of the support device 11 and is in the shape of a lump can be peeled off and removed with the high-pressure water 106.

The high-pressure water 106 is sprayed onto the support device 11 from multiple directions such as upward and downward to ensure removal, but at that time, the spray 92 is moved to the trolley device 12 side by the cover 92 and the movable cover 94. It is possible to prevent the trolley device 12 and the like from being rusted. Further, the dropped paint is received by the liquid surface 100 and does not drop directly onto the movable table 88 or the linear motor section.

After performing the intended cleaning, the moving body transport device 64 is moved again to be positioned at the outlet 74 as shown by the phantom line E in FIG. 1, and the support rail 91 is connected to the rotary rail 68. Then, after the movable cover 94 is opened, the carriage 10 supported by the support rail 91 is transferred to the rotary rail 68 by the feeding device or manually to bring it to the state shown by the solid line F in FIG. The support device 11 is returned upward as shown by the phantom line G in FIG. The trolley 10 on the rotary rail 68 is fed onto the first rail 1 by a feeding device or manually and is moved via the endless rotary body 41, and then faces the inspection device 66 as shown by a solid line H in FIG. And then stopped.

The reciprocating traveling of the movable table 80 in the moving body transport device 64 described above is performed by operating the linear motors 96 and 97.
It is performed on a fixed route 79 while being guided by the rail 81. Then, the movable table 80 moves in the liquid tank 75, but at that time, the entire lower part of the support rod 89 than the middle part is submerged.

As shown in FIGS. 4 and 5, after the carriage 10 is stopped so as to face the inspection device 66, first, the locking device 111 is operated to act on the locking pin 109 to correct the position and position of the carriage 10. And do. Next, the elevating frame 116 is lowered by the operation of the cylinder device 114, and as shown in FIG.
The receiving tool 118B for the receiving pin is fitted onto 2B. Such fitting is done when the receiving pin 32B is normal,
For example, when the receiving pin 32B is out of position, the lifting frame 1
Although the rod 119 is left in the state where 16 is lowered, the striker 123 swings the lever 124 outward, and the limit switch 125 is detected. Receiver 32A
Is detected in the same manner, and at that time, the trolley 10
Is moved forward a little. However, the receiving tool 32A and the receiving pin 32B may be detected at the same time.

In this way, the inspection device 66 inspects whether or not the supporting position of the supporting device 11 is normal, and the carriage 10 whose supporting position is normal is returned from the cleaning moving route 56a to the moving route 56. Further, the carriage 10 in which the abnormality is detected is moved from the cleaning moving path 56a to the repairing moving path 56b, repaired here, and then returned to the moving path 56.

In the above-described embodiment, the form of removing the paint and the like by the water jet method has been shown, but a chemical treatment liquid may be used as the liquid 78 and the support device 11 may be submerged to remove the paint and the like. Further, a shot blast type may be adopted, and in this case, a chain conveyor type or the like may be adopted instead of the submerged linear motor type.

In the case of the submerged linear motor type, there is no dust or dust on the traveling part, explosion-proof specifications can be easily made, and maintenance of the truck can be easily performed.

EFFECTS OF THE INVENTION According to the present invention having the above-described configuration, the moving body that has moved along the moving path can be turned downward by rotating the rotation rail of the upstream reversing device so that the supporting device can face downward, and the moving body is conveyed by the moving body conveying device. The cleaning device can then be used to clean the downwardly facing support device. The moving body that has completed the intended cleaning can be returned so that the supporting device faces upward by reversing by the rotation of the rotating rail in the reversing device on the downstream side, and can be moved again on the moving path. In this way, it is possible to easily perform cleaning (paint removal, etc.) on the support device of the moving body online without removing it from the moving route, and by dividing the rail by the moving body conveying device, the liquid agent used for cleaning It is possible to prevent such things from flowing along the rail and adversely affecting the intended line.

Further, according to the configuration of the present invention, the cleaning device finishes the intended cleaning, and the downstream reversing device determines whether or not the supporting position of the moving body facing upward is normal on the supporting device of the moving body. It can be easily inspected by an inspection device.
