PROBLEM TO BE SOLVED: To provide an opening holding device of a bag body capable of opening and holding the bag body one by one without using hands to a plurality of overlapping bag bodies.SOLUTION: A plurality of overlapping bag bodies 70 are set to a base table 11. When an auxiliary arm 20 and an operation arm 30 rotate to the base table 11, a first suction part 22 provided at the auxiliary art 20 is positioned at the outside of the bag body 70 at the time of approaching the base table 11. On the other hand, a second suction part 32 provided at the operation arm 30 is positioned at an inner side of the bag bodies 70 at the time of approaching the base table 11 and absorbs an opening end of a bag body 70 placed on a very top among the plurality. Because the second suction part 32 is transferred to the first suction part 22 by transfer means while absorbing the bag body 70, the first suction part 22 absorbs a reverse side of the bag body 70 near the opening end. When the operation arm 30 rotates back to the original position, the bag body 70 is opened and held while being pulled between the second suction part 32 and the first suction part 22. |
