Patent ID: 8123914

Claim:
An electrode plate transportation apparatus that lifts and lowers electrode plates moved to a position above an electrolytic bath and places and draw the electrode plates in and from the electrolytic bath, comprising: a stationary frame that is suspended from an upper position in a vertical direction; a rotary unit that is composed of hold members for holding the electrode plates in a suspended state and is held so as to rotate in a rotational direction about the vertical direction by the stationary frame; and a drive mechanism that is provided between the stationary frame and the rotary unit and applies drive force along an one-axis direction in a plane perpendicular to the vertical direction to the rotary unit to thus drive the rotary unit in the rotational direction and adjust the attitudes of the electrode plates that are held by the hold members against the electrolytic bath with respect to the rotational direction, wherein the rotary unit includes: a rotary frame that is provided above the stationary frame and the drive mechanism and is rotated about the vertical direction in response to the drive force by the drive mechanism; a base frame that is provided below the stationary frame and supports the hold members; and joint members that join the rotary frame and the base frame.
