[Effects of the invention] As described above, the present invention has an inclined shelf made of several rails having a stop piece projecting upward from the processing liquid tank at the front end, which is disposed inside the processing liquid tank. The shafts at both ends of the beam are rotatably supported on the tops of a pair of pillars erected on both sides of the beam, and a lifting frame with an inclined fork is connected to a rod that protrudes downward from an actuator erected on the beam. The lifting frame descends when tilting forward about the shaft, rises when tilting backward, scoops up the workpiece on the inclined shelf, and processes the workpiece from the fork above the stop piece of the liftframe. Since it is moved to the front of the liquid tank, it has the following effects.

When the lifting frame scoops up the object to be processed above the stop piece at the front end of the inclined shelf, the object to be processed rolls from the lifting frame to the outside of the processing liquid tank, and another processing liquid tank is immediately moved forward. Once placed, the objects to be processed are directly sent to the inclined shelf of the processing liquid tank in front.

Since the entire elevating frame is tilted toward and away from the front end of the inclined shelf, the structure of the elevating frame is simple and the repetition of operations becomes simple.

When the outer dimensions of the objects to be processed are different, by adjusting the amount of tilting of the lifting frame, the amount of protrusion of the fork toward the lower side of the inclined shelf is adjusted, and the objects to be processed can be scooped up one by one.

Since the supply device and the discharge device are integrated with the treatment liquid tank, if a large number of surface treatment devices according to the present invention are installed in parallel at the front and back, it is possible to continuously perform various surface treatments on the object to be treated. By shortening or lengthening the repeated operation time of the device, each treatment time can be freely adjusted.

Since the supply device and the discharge device are integrated into a unit with the processing liquid tank, the processing liquid tank can be easily added when changing the treatment process of the object to be processed.
