Abstract:
1. A method of supplying bags toward a belt conveyor of a conveyor magazine-type bag-supply apparatus of a packaging machine comprising the steps of: creating, in a horizontal-type bag-making machine, connected empty bags joined in belt-like fashion as a belt-like film is fed sequentially in a longitudinal direction of the belt-like film and then cutting off individual bags from the connected empty bags, placing empty bags fed out from the horizontal-type bag-making machine onto a positioning conveyor and conveying the empty bags while positioning the empty bags at a prescribed position on the positioning conveyor, moving the positioned empty bags upward, changing the empty bags into a vertical attitude in which bag mouth portions of the empty bags face downward, transporting the empty bags horizontally toward a predetermined location, while maintaining the vertical attitude thereof, and rotating the empty bags within a horizontal plane so that a bag surface orientation of the empty bags is changed 90 degrees, then changing the vertically-oriented empty bags to a horizontal attitude, and placing the empty bags on a supply conveyor, and conveying and supplying the empty bags horizontally on the supply conveyor toward the belt conveyor of the packaging machine.
