Patent ID: 6945008

Claim:
A packaging system for causing articles to fall downward along a predetermined falling route and filling said articles into a tubular film thereby producing packaged products, comprising: sealing means operating on said falling route after an interval from a time when the articles fall down, for sealing an end of said film in a direction orthogonal to a transfer direction of said film; a bite detecting means for detecting the presence or absence of articles being bit into a sealed portion of said film sealed by said sealing means; and a controller comprising: determination means for determining whether a state of a flow of the articles on said falling route is normal or abnormal, based on the presence or absence of articles being bit into the sealed portion; and change means for changing the interval according to the state of the flow of the articles determined by said determination means, wherein a system feedback controls the interval based on a signal indicating the state of the flow inputted from said determination means.
