<P>PROBLEM TO BE SOLVED: To prevent breakage resulting from the shrinkage of a flexible air hose in a sucking operation performed by a suction blower. <P>SOLUTION: A parallel robot 1 is provided with a first fixed air hose 10 which is fixed to a base 2 and extends from the suction blower 7 to its lower side, a second fixed air hose 11 which is fixed to one of links 41A constituting pairs of parallel links 31, 41, 51 and whose lower end is coupled to a suction pad 6, and a retractable and flexible air hose 12 which is built between the first fixed air hose 10 and second fixed air hose 11 and whose one end is coupled to a lower end of the first fixed air hose 10 and whose other end is coupled to an upper end of the second fixed air hose 11. The one end of the flexible air hose 12 is provided so as to be turnable in such a direction as to allow the shrinkage of the flexible air hose 12 in relation to the lower end of the first fixed air hose 10 between the first fixed air hose 10 and the second fixed air hose 11 when the suction pad 6 performs its sucking operation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
