をその目的としている。The above-mentioned method is suitable for a chemical conversion treatment or an electrodeposition coating treatment. However, the resistance is large in the treatment liquid, and the work cannot be rotated at such a speed. Since the replacement of the processing liquid inside the work is not promoted to the left by only the above, there is a problem that the processing efficiency does not increase to the left in the degreasing process or the cleaning process for removing oil, dust and the like attached to the work. In view of the above, an object of the present invention is to provide a surface treatment method suitable for mainly degreasing treatment and cleaning treatment, which can efficiently treat the entire inner and outer surfaces of a work.

た。1 shows a hanger 1 for transporting an automobile body W as a work along a processing line. The hanger 1 is rotatably supported on a pair of left and right conveyor rails 2 and 2 via rollers 3 respectively. A pair of left and right hanger frames 4 to be hung are attached to a lower end of a hanger frame 4, and a longitudinally extending support frame 5 is attached thereto.
The hanger 1 is moved by the drive unit 8 equipped with the motor 7 controlled by the controller 6 to the conveyor rails 2, 2.
, And a jig 9 for holding the vehicle body W with the vehicle lengthwise sideways is hung on the hanger 1 so as to be vertically movable and rotatable about a horizontal axis in the vehicle lengthwise direction. . In more detail, a pair of sprockets 10 and 10 are fixed on both ends of the jig 9 on the same horizontal axis, and chains 11 are wound around the sprockets 10 and 10 respectively. , A pair of hoists 12, 12 are mounted on the hanger 1, one end of both chains 11, 11 on one hoist 12, and the other end of both chains 11, 11 on the other hoist 12, respectively. through the guide member 5a on the support frame 5 is connected, by lowering or raising the more jig 9 to rotate both hoist 12 and 12 together in the unwinding direction or winding direction, processes in the processing line The jig 9, that is, the vehicle body W is rotated around the horizontal axis in the vehicle length direction by moving the vehicle body W into and out of the processing tank 13 disposed in the station and further rotating the both hoists 12, 12 in opposite directions. I got it. Further, in order to prevent the jig 9 from swaying when the jig 9 is moved up and down or rotated, a pair of guide frames 14, 14 engaging with the shaft portions 10 a of the sprockets 10 are provided at both ends of the processing tank 13.
On the other hand, a pair of guide frames 5b, 5b engaging with the shaft 10a are also provided at both ends of the support frame 5 of the hanger 1.
To prevent the jig 9 from swaying during the transfer.

せ、処理を完了する。The illustrated processing tank 13 is a processing tank provided in a degreasing or cleaning station, and contains a processing liquid (degreasing liquid or water) up to about half of the inside of the tank. A large number of spray nozzles 15 are provided so as to surround the vertical trajectory of the vehicle body W. At the time of processing, the hanger 1 is stopped at a position immediately above the processing tank 13, then the jig 9 is lowered, the vehicle body W is put into the processing tank 13, and the lower half of the vehicle body W is immersed in the processing liquid. In this state, the body W is rotated about the horizontal axis in the vehicle length direction while spraying the processing liquid onto the portion of the body W exposed on the liquid surface by the spray gun 15.
In this case, the vehicle body W may be continuously rotated in one direction, but the vehicle body W is repeatedly rotated to one side and the other side in a predetermined angle range, for example, in a range of 90 ° to 180 ° when viewed from the side of removing dust and the like. Rotating is more efficient. Then, after a lapse of a predetermined processing time, the jig 9 is lifted and the vehicle body W is discharged from the processing tank 13 to complete the processing.

の振れを生じないようにするためである。In order to reduce the resistance received from the liquid surface at the time of entering and exiting the tank, and also to perform the treatment of the roof and floor bottom occupying most of the outer surface of the vehicle body by spraying at the time of entering and exiting the tank, It is desirable that the vehicle enters and exits with the vehicle width direction facing up and down in a sideways posture. In this case, after entering the tank, the vehicle body W is returned to the horizontal position, and the horizontal position is set to the neutral position, and the vehicle body W is repeatedly rotated one and the other. Move. When the liquid level in the processing tank 13 is high, the vehicle body W may be temporarily immersed in the processing liquid and then raised to be in a semi-immersed state.
Further, in the above-described embodiment, the batch-type surface treatment equipment for entering the processing tank 13 with the transportation of the vehicle body W stopped is used. The present invention can also be applied to a case where a continuous transport type facility for performing the above is used, and in this case, it is desirable to transport the vehicle body so that the vehicle length direction is in the front-rear direction. This is because when the vehicle body is rotated around the horizontal axis in the vehicle length direction, the resistance received from the processing liquid due to the transportation of the vehicle body is changed so that the vehicle body does not shake.
