A tube-plug extracting apparatus has a clamping mechanism, movable frame, chucking mechanism, rotation mechanism, and vertical motion mechanism. The clamping mechanism holds a test tube upright. The movable frame is located over a plug extracting position and slides in a vertical direction. The chucking mechanism chucks a plug attached to the test tube. The rotation mechanism rotates the chucking mechanism. The vertical motion mechanism moves the movable frame in a direction to extract the plug. The vertical motion mechanism has ball screws and a drive motor. The ball screws have a stroke long enough to move the movable frame in order to shift a lower-limit stop position for chucking the plug corresponding to the size of test tube. |
