Packing article - including according to detection device for the final sealing frame of the angle of attack

摘要

Disclosed is a packaging article inclusion-proofing device for an end-sealing mechanism having: a motor (A) for driving a conveyor (12) for feeding packaging articles (10) with a predetermined space therebetween into a packaging material (16) which is delivered downstream being formed into a tube; a motor (B) for driving a series of rolls (18,34) which deliver downstream the packaging material (16) being formed into a tube; and a motor (C) for driving an end-sealing mechanism (20) for achieving end-sealing of the tubular packaging material (16) in the crosswise direction relative to the line of feed, characterized by the constitution comprising: a deviation detecting sensor (42) disposed at a predetermined position upstream the end-sealing mechanism (20), for detecting deviation of packaging articles (10) having been inserted to the tubular packaging material (16) relative to the portion to be end-sealed; a reference timing pulse generating means (S1) which generates predetermined reference timing pulses for the timing of feeding the packaging articles (10) from said conveyor (12); and a means for stopping the motor (C) for driving the end-sealing mechanism (20) with gradual deceleration, provided that a deviation timing signal preset based on said reference timing pulse generating means (S1) should coincide with the deviation detection signal from the deviation detecting sensor (42), and starting said motor after a duration of stopping it for the number of cycles in which inclusion of deviated packaging articles (10) by the end-sealing mechanism (20) is expected to happen to gradually accelerate it until the speed and phase thereof may be synchronized with those of said motor (A) for driving the conveyor (12) and those of said motor (B) for feeding the packaging material (16).
