A take-up pulley 73 attached to the carriage 72 and a guide pulley 74 attached to the right end portion of the guide rail 71 so as to be located almost directly above the other end fixing portion of the energizing cable 63 are provided. A balancer rope 76 of a take-up balancer 75 is connected to the carriage 72, whereby the take-up pulley 73 is urged in a direction in which the take-up pulley 73 is separated from one end fixing portion of the energizing cable 63 and the guide pulley 74. In addition, in the immediate vicinity of the guide pulley 74, a pair of stopper pulleys 77 are arranged. Then, the energizing cable 63 is first wound around the take-up pulley 73 from the lower end to the guide pulley 74 by being wound from the one end fixed portion, and then is wound around from above to the guide pulley 74. It is passed from between the slip-off prevention pulley 77 and hung down.

When the carrier 19 is carried over the processing tank 11, the carrier 19 is stopped and both hoists 43 are rewound at the same time. Then, the lengths of the U-shaped straight portions of both the suspension ropes 22 become long, and the wheel 24 descends together with the transported object support frame 26 without rotating. At this time, the guide member 52 is first guided by the upper guide rail 41 and then by the lower guide rail 31, so that the conveyed object support frame 26 descends in a stable posture without wobbling. Eventually, when the vehicle body W supported by the transported object support frame 26 is immersed in the liquid in the processing tank 11, this time, one hoist 43 is wound and the other hoist 43 is unwound. Then, one of the U-shaped straight portions of the two suspension ropes 21 is pulled up, and the other is pulled down, so that the wheel 24 is rotated and the transported object support frame 26 is also rotated together with the wheel 24. As a result, the transported article W supported by the transported article support frame 26 is rotated, and even if there is air pocket in the transported article W, the air there is replaced with the liquid and the air pocket disappears.

Although FIG. 1 shows a state in which the conveyed article W is rotated 90 degrees in the processing tank 11 from the time of conveyance, it is conveyed by 90 degrees or more, for example 180 degrees, and if necessary, 180 degrees or more. Of course, the object W can be rotated.

When the lower end of the energizing cable 63 is pulled downward as the conveyed object support frame 26 descends, the take-up pulley 73 moves in a direction approaching the guide pulley 74, and the take-up pulley 73 moves away from the carrier 19. If the energizing cable 63 is pulled out freely and the energizing cable 63 tries to be loosened as it rises, the take-up pulley 73 moves toward the guide pulley 74 and the energizing cable 63 It is pulled into the carrier 19 while being stretched.

[0024]

[Effect of the device]

 According to the present invention, the take-up pulley moves in a direction away from one end of the current-carrying cable even if the current-carrying cable is loosened in the process of raising the object-supporting frame as the goods-supporting frame is moved up and down. Therefore, the energizing cable is always stretched, and the energizing cable is guided almost straight down from the guide pulley to the conveyed object supporting frame, so that the space occupied by the energizing cable is extremely small. Therefore, it is possible to eliminate the slack in the energizing cable and prevent the energizing cable from interfering with transportation work.
