2. Description of the Related Art Conventionally, in a wrap-around type boxing machine such as a wrap-around caser for packaging items to be packaged, such as miso bag-packaged items, when the items to be packaged are stacked and packed in a box. Before supplying blank sheets, the items to be packaged are stacked in advance to form a stack of one box,
A system (for example, Japanese Unexamined Patent Publication No. 56-113520) is generally adopted in which the accumulated articles corresponding to one box are collectively fed to the article accommodating portion on the blank sheet. In this method, the accumulated articles can be surely supplied to the article container, but the outer shape is not block like the bag-packaged article, for example, so that the packaged article may be deformed by pushing. However, there is a problem in that the amount of material fed into the article container is not constant.
Further, it is pointed out that when the accumulated articles are pushed, the objects to be packaged are damaged and the commercial value is lowered.

As a measure against the above-mentioned problems, for example, a method of sucking and holding a predetermined number of articles to be packaged by a robot or the like and transferring them individually to an article storage section (for example, JP-A-7-125706, JP-A-7-125706). 11-7910
No. 7) is adopted.

[0004]

In any of the above-mentioned prior arts, the object to be packaged is partially deformed by the pressing at the time of pushing and the pulling by suction, such as a bag packaged product of a viscous material such as miso. If it is easy and does not return to its original shape after being deformed, there is a problem that the product loses its shape in the process of being transferred to the article accommodating portion and the commercial value is significantly reduced.
