When cleaning the object to be cleaned, the transporting device shown in FIG. 1 is arranged at a predetermined position outside the primary cleaning tank, and the cleaning basket 17 containing the object to be cleaned is positioned at a predetermined position outside the primary cleaning tank. Deploy.

Then, with each movable locking member 16 arranged in the inoperative position, the lifting air cylinder device 6 is operated to lower each movable locking member 16 toward the washing basket 17, and each movable locking member 16 is moved. The hook 19 of the locking member 16 is the cleaning basket 1
When the handle 18 is placed at a predetermined position below the upper horizontal portion of the handle 18 (see FIG. 2), the descent is stopped. In this state, the opening / closing air cylinder device 10 is operated to move the elevating shaft 11 to the lower end position, whereby the movable locking members 16 are rotated in the directions in which they are separated from each other, and the respective hooks 19 thereof are washed. It is arranged directly below the handle 18 (see the solid line position in FIG. 2). Then, the elevating air cylinder device 6 is operated again to raise the movable locking members 16. At this time, the hook 19 of each movable locking member 16
Engages with and hangs the upper horizontal portion of the handle 18 of the cleaning basket 17 and raises the cleaning basket 17 to a position higher than each tank such as the primary cleaning tank.

Next, the carrying motor 4 is operated in the above state, the carrying device is moved to a position corresponding to the primary cleaning tank and stopped. At this position, the lifting air cylinder device 6 is operated to lower each movable locking member 16, and the cleaning basket 17 hung on each hook 19 is dipped in the cleaning liquid in the primary cleaning tank for a certain period of time, and the cleaning basket is then washed. The object to be cleaned in 17 is cleaned. When the cleaning for a certain period of time is completed, the lifting air cylinder device 6 is operated to raise each movable locking member 16,
The cleaning basket 17 escapes upward from the primary cleaning tank. When the cleaning basket 17 is arranged above, the solenoid valve for each air nozzle 15 is opened, and the compressed air is ejected from each air nozzle 15 toward the object to be cleaned in the cleaning basket 17, and the surface of the object is cleaned. The adhered polka-dotted cleaning liquid is blown off and dropped into the primary cleaning tank to reduce the cleaning liquid on the surface of the object to be cleaned as much as possible. This action is effective in reducing the amount of the cleaning liquid brought into the secondary cleaning tank in the subsequent water washing step as much as possible to reduce water contamination and efficiently performing the water washing.

Next, the solenoid valve for each air nozzle 15 is closed and the transfer motor 4 is operated to move the transfer device to a position corresponding to the secondary cleaning tank and stop it.

Let

At the same time that each movable locking member 16 rotates in the approaching direction, the solenoid valve for each air blowing pipe 20 is opened, and compressed air is discharged from a large number of air blowing holes of each air blowing pipe 20 to be cleaned. Water droplets and water remaining on the object to be cleaned are blown away. In this case, since each air blowing pipe 20 moves in an arc along with the rotation of each movable locking member 16, it is possible to blow the compressed air evenly over each lower portion of the cleaning basket 17 to each cleaning target. it can. Therefore, the subsequent drying action can be further promoted.

At this point, after each movable locking member 16 is placed in the inoperative position and the solenoid valve for each air blowing pipe 20 is closed, the lifting air cylinder device 6 is operated and each operation locking is performed. The member 16 is lifted above the drying tank. After that, the opening of the drying tank is closed with a lid (not shown), and the inside of the drying tank is heated by a heater to heat and dry the object to be cleaned.

After the drying is completed, the lid of the drying tank is opened, the lifting air cylinder device 6 is operated to lower each movable locking member 16, and the hook 19 of the hook 19 is located above the handle 18 of the cleaning basket 17. At a position slightly lower than the position of the movable locking member 16 by operating the opening / closing air cylinder device 10 and lowering the lifting shaft 11 thereof.
