CONTINUOUS ROTARY FILLING AND PACKAGING MACHINE

Provided is a continuous rotary filling and packaging machine that covers a container body B with a molded lid P and heat-seals the container body B and the molded lid P to produce a sealed container, the continuously rotary filling and packaging machine including a sealing device that substantially reduces occurrence of a sealing failure that is caused because the molded lid is not placed on the container body or not properly placed on the container body. A continuous rotary filling and packaging machine that covers a container body with a molded lid and ultrasonically seals the container body and the molded lid to produce a sealed container includes a lid detecting device 70 disposed on the downstream side of the lid supplying device 60 and an ultrasonic sealing device 100 including lifting and lowering means including a cam mechanism for lifting and lowering a container table 103, the lifting and lowering means being configured such that the molded lid on the container body and a seal working surface of an ultrasonic horn 108 come into press-contact with each other at a top dead point of the container table, and a container table lowering control mechanism that does not lift, to the top dead point, a container table of a container whose container body does not have the molded lid placed thereon or properly placed thereon as determined.
