<P>PROBLEM TO BE SOLVED: To improve the quality of heat sealing without increasing a work burden of an operator in a sealing apparatus of a packaging bag. <P>SOLUTION: The sealing apparatus of the packaging bag includes: a conveyor 4 for conveying a box body 2 in which a packaging bag 3 for storing an article is placed; and a sealing mechanism 5 for pinching an upper end part of the packaging bag 3 which is placed in the box body 2 conveyed by the conveyor 4 and sealing it by heat sealing, and has a plurality of nozzles 51a, 51b, 52a and 52b arranged above the conveyor 4 and on the upstream side of the sealing mechanism 5. A plurality of the nozzles 51a, 51b, 52a and 52b are mutually opposed by pinching the central line s of the conveyor 4, and are arranged in a reverse V-shape in which the mutual distance dimension is gradually decreased in the advancing direction (X1 direction) of the conveyor 4. On its upper face, there is formed an air blowing opening 55 to blow air upward from the air blowing opening 55 to the packaging bag 3 placed in the box body 2 conveyed by the conveyor 4. <P>COPYRIGHT: (C)2011,JPO&INPIT |
