<p><P>PROBLEM TO BE SOLVED: To provide a double packaging apparatus which further encloses in an outer bag, a bag that is filled with a material to be filled by using the conventional bag-making/filling apparatus. <P>SOLUTION: An inner bag supply mechanism includes: a conveyor 23 for dropping the inner bag C on a conveyed belt-like packing material S; and a pushing-out bar 27 having a pushing-out piece 29 which is abutted on the dropped inner bag C to push-out the abutted inner bag to the side of a vertical tentatively-sealing part K. A chuck mechanism 35 for chucking the packing material S is arranged between the dropped position of the inner bag C and a tentatively sealing position. After the pushing-out piece 29 is abutted on the inner bag and pushes out the inner bag to the side of the vertical tentatively-sealing part K, the chuck mechanism 35 is closed. The pushing-out piece is abutted again on the inner bag through an aperture of the chuck mechanism 35 to push-out the abutted inner bag to the side of the vertical tentatively-sealing part K. Since the inner bag C is pushed out to the inside of the packing material S folded almost in two by the chuck mechanism 35, the inner bag C can be brought to a predetermined position. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
