Abstract
A packaging article inclusion-proofing device for use with an end-sealing mechanism includes a motor for driving a conveyor for feeding packaging articles, with a predetermined space therebetween, into a packaging material which is disposed downstream and formed into a packaging tube, a motor for driving a series of rolls which deliver the packaging material, and a motor for driving an end-sealing mechanism for achieving end-sealing of the tubular packaging material. A deviation detecting sensor is provided for detecting any deviation of the packaging articles from a position at which they would normally be disposed during the end-sealing operation. A reference timing pulse generator generates predetermined reference timing pulses with respect to the feeding of the packaging articles. The motor drive for the end-sealing mechanism is stopped when a deviation timing signal, based upon a reference timing pulse, coincides with a deviation detection signal from the deviation detecting sensor, and the motor drive is restarted after a predetermined cycle time period elapses which would encompass all of the packaging articles disposed at the deviated positions, whereby proper synchronizati…
