By the way, the gripping means 2 of the pre-operation gripping portion is at the position indicated by the dotted line, and when the bag 1 is sucked up by the suction device B, the operation arm 14 is continuously driven so that the bag 1 is immediately gripped and the swing arm 3 is swung. Is swung from point a to point b. FIG. 6 is a locus diagram of the bag gripping means 2. Initially, by swinging the swing arm 3 circularly as described above, the bag 1 is lifted while being linearly pulled out obliquely upward from the laterally placed bag storage device A, and finally. The bag is hung vertically along the swing path of the auxiliary swing arm as shown by the dotted line in the figure to reach a predetermined gripping position, and is handed over to the table-side gripping mechanism D. (In the drawings, (1) to (4) show the operation sequence corresponding to the swing arm 3, the gripping means 2, and the auxiliary swing arm 5, respectively.) Then, when performing the bag feeding operation for the next bag, the operation arm 14 is operated.
Is driven in the opposite direction to the forward direction, and the swing arm 3 is swung from the point b to the point a.
