PURPOSE:To enhance working efficiency, by a method wherein a bag sucked one at a time is moved to the position of a filling mechanism in an opened state by a grasping and moving mechanism and again grasped at the other part thereof by the grasping claw of a grasping mechanism to be filled and, at the same time, the grasping and moving mechanism is returned to the bag take-out position while the grasping mechanism is moved to a seal mechanism to successively perform packing. CONSTITUTION:The arm 7 of the suction mechanism 2 is revolved to the part above stacked bags 1 and a suction cup 8 is operated to suck the bag 1 one at a time. The air cylinder of a left and right moving mechanism 17 is operated and the grasping claw 12 grasping the bag 1 is pushed out to the position directly under a filling mechanism 4. Both surface of the bag 1 sucked by a suction cup 15 are drawn outwardly by the bending of a bending lever 14 to be opened. At this time the second cylinder of a grasping mechanism 5 is also operated and the second grasping pawl 28 grasps both ends of the upper part of the opened bag 1. A grasping and moving mechanism 3 returns to the position of the suction mechanism 2 to grasp the bag 1 standing by for taking-out and moves in the same way as mentioned above. When the bag 1 is filled with a definite amount of an article to be filled by the filling mechanism 4, the grasping mechanism 5 is moved to a seal mechanism by the second left and right moving mechanism to seal the bag.
