ABSTRACT:
A handling robot includes at least four bosses (20a, 20b, 20c, 20d) disposed in a transfer chamber so as to be coaxial with one another and rotatable independently of one another. The bosses are deviated (staggered) in their positions along the axis of a center of rotation. Each of the bosses is provided with an arm (21a, 21b, 21c, 21d), respectively. A link (22a, 22b, 22c, 22d) is coupled to each of the arms, respectively. Two of the bosses which are adjacent to each other in an axial direction constitute a pair. A transfer table (8a, 8b) is coupled via a transfer table attitude regulating mechanism (B) to the respective leading ends of each pair of links. The links are, in turn, coupled to an arm of the pair of bosses to provide a plurality of transfer tables which are arranged so as to be deviated in their positions towards the axis of the center of rotation. An independent drive source (27a, 27b, 27c, 27d) is coupled to each of the bosses, respectively.
