A packaging device provided with a bag take-out section (32) for separating and taking out a large number of accommodating bags (27) stacked in the bag accommodating section (3) one by one in order from the uppermost one. There is a first suction part (N1) which acts on the uppermost storage bag (27) by suction, and a first suction part (N1) which vertically moves the first suction part (N1) close to and away from the bag storage part (3). The suction part moving mechanism (A) is provided in the bag taking-out part (32), and the uppermost containing bag is accommodated by driving the first suction part (N1) and the first suction part moving mechanism (A). (27) is configured to be separable, and a pair of second adsorption parts (N) that adsorb from the front and back sides of the bag in the vicinity of the opening (27a) of the separated storage bag (27).
2) to a pair of movable first and second support arms (4
8) and (49) are separately supported, one first support arm (48) is interlockingly connected to the drive unit (M5), and the pair is provided near the opening (27a) of the separated accommodating bag (27). Of the drive unit (M2) with the second suction unit (N2) of
5) As the first support arm (48) is driven to move in the front-back direction of the accommodation bag (27), the second support arm (49) causes the first support arm (48) to move in the front-back direction. ), The second support arm (49) is interlocked with the first support arm (48) so that the opening (27a) of the accommodation bag (27) is opened. apparatus.
