Claims

[Claims for Utility Model Registration] (1) A bag support unit that supports bags having an opening at a position lower than the top end in a bundle by pinching the top ends thereof, and a bag that is turned over and hangs from the bundle of bags. A package comprising: a blowing means for blowing air into the opening of the bag to open it; and a heat-sealing section that is movable and heat-seals the lower side of the opening of the bag from both the front and back sides after filling is completed. In the device, a pair of fixed claws is slidably supported by a rail member provided substantially parallel to the width direction of the bag, and a pair of fixed claws is movably supported by each of the fixed claws, and when moved to the fixed claw side. A movable claw that is closed together with the fixed claw and clamps both ends of the bag in the width direction; an elastic member that holds the movable claw in the open state and the closed state, respectively; a link mechanism that is pin-coupled to the fixed claw, and causes the fixed claw to approach when the rail member is driven toward the front surface of the bag, and to separate the fixed claw when the rail member is driven toward the back surface of the bag; a claw closing mechanism that moves the rail member toward the front surface after pressing the movable claw to move it in the closing direction; and a claw closing mechanism that presses the movable claw after moving the rail member toward the back surface. A packaging device characterized by comprising a claw opening mechanism movable in an opening direction. (2) Timing control in which the claw closing mechanism is driven before the opening operation by the air blowing means, and the claw opening operation by the claw opening mechanism is performed after the heat sealing section has sandwiched the opening of the bag from both the front and back sides. The packaging device according to claim 1, characterized in that the packaging device comprises:
