<P>PROBLEM TO BE SOLVED: To make a transport part automatically open when necessary without excessively increasing cost of a packaging apparatus, and to easily achieve high-productivity packaging work. <P>SOLUTION: In this packaging apparatus including, in an intermediate part of a transport path 10, a welding and cutting part 30A where a heater plate 31a for welding and cutting a resin film in the width direction is arranged to be capable of advancing/retracting operation and advances to a welding position by drive force of a motor, and a transport part 40A where a pair of roller conveyers 41, 42 for transporting an article 200 to the downstream side by sandwiching it therebetween on the downstream side thereof are openably/closably arranged, the heater plate 31a advances to the welding position by normal rotational drive of the motor, at least one of the roller conveyers 41, 42 is allowed to move in the opening/closing directions, urged in the closing direction, and opens the transport part 40A by reverse rotational drive of the motor; the motor performs reverse rotational drive by inserting the article 200 in a predetermined situation; and the closed transport part 40A receives the tip side of the article by opening the inlet side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
