Detailed Description of the Invention

[Object of the Invention]

(Field of Industrial Application) The present invention relates to an apparatus for supplying articles to a packaging section in a packaging machine. (Prior Art) Conventionally, as shown, for example, in Japanese Utility Model Publication No. 58-3402, an article cradle mechanism that moves up and down is provided with a plurality of loading rods, and each loading rod is supplied from a transport unit. There is known a wrapping machine that pushes up an article toward a packaging section and lifts the packaging film stretched in the packaging section by bringing the upper surface of the article into contact with the lower surface of the packaging film. (Problems to be Solved by the Invention) However, in the conventional packaging machine, since the placing plane of the article receiving mechanism formed by each placing rod is constant, for example, the size of the article to be placed is large. If too much, the article supplied from the transport section cannot be stably supported on the placement plane, and if the article cradle mechanism is raised toward the packaging section from that state, the article may be dropped.
