In this type of packaging machine, it is required to support each packaging process by holding a packaging bag or the like in carrying out each packaging process. For example, it is required to suppress the shaking of the packaging bag after filling the packaged object, or to give vibration to the packaged bag in order to promote the dropping of the packaged object in the packaging bag.

そして、例えば前者については円周ガイド等のガイドで包装袋を押さえ包装袋の振れを抑制し、後者については包装袋の底部をタッピングする振動手段等により落とし込みを促進していた。 Then, for example, in the former case, the packaging bag is pressed by a guide such as a circumferential guide to suppress the runout of the packaging bag, and in the latter case, the dropping is promoted by a vibrating means or the like tapping the bottom of the packaging bag.

しかし、前者の場合、製品毎に異なる高さ調整を十分に行えないという問題があった。また、これまでの包装機は、包装工程の中で、包装袋を保持等して補助できる工程が限られていた。 However, in the former case, there is a problem that different height adjustments cannot be sufficiently performed for each product. Further, in the conventional packaging machine, in the packaging process, the process of holding and assisting the packaging bag has been limited.
