Tube transferring device

A tube transferring device for transferring tubes positioned in predetermined positions among a plurality of tubes in a storage where the tubes are arranged, the device comprising:

• a body;
• a suction structure including suction members positioned on a lower surface of the body, the suction member being configured to maintain contact with an upper surface of the tube by sucking air;
• an elastic structure including pusher blocks protruded from a lower surface of the body and first and second side pusher blocks extending in a first direction by spacing apart from the suction members and the pusher blocks on the lower surface of the body, at least one pusher block being positioned between the suction members on the lower surface of the body, the first and second side pusher blocks being positioned in both lateral portions of each of the suction members and the pusher blocks, the first and second side pusher blocks having a bar shape, the elastic structure providing elastic force to an upper surface of the tube in a direction from the body to the tube;
• a gripper gripping or releasing the tube contacted with each of the suction members;
• and
• a controller configured to:
• control the suction members so that the suction members suck air or do not suck air, and
• control the gripper so that the gripper grips or releases the tubes.
