2. Description of the Related Art As a conventional general rotary packaging machine, a large number of grip pairs are projected in a radial direction of a rotating body, and supplied packaging bags are sequentially held by each grip pair in a hanging manner to form an opening station. While intermittently moving to each station such as a filling station, a top sealing station, etc., a predetermined amount of articles to be packaged is filled by a filling funnel within a stop time of one process, a bag mouth is sealed, and then discharged outside the machine. One having such a configuration is known from Japanese Utility Model Publication No. Sho 62-21521. In addition, after carrying out large dispensing with the packaging bag gripped on the filling table side, re-grip with the grip of the quantitative detector, dispensing and dispensing and weighing with the quantitative detector, and packing after filling, Japanese Patent Publication No. 6-29043 discloses a weighing and packaging method in which a bag is gripped again on the filling table side and then delivered to a seal table to seal the bag mouth. Others
In an apparatus used for a vertical bag-filling and packaging method in which a film sheet is fed to a former to form a bag, and the product is weighed and supplied to the bag-making process, the weight of the former and the film sheet is loaded into a load cell. Japanese Patent Application Laid-Open No. Hei 11 (1999) discloses a technique for measuring the weight of a filled product by subtracting the weights of a known former and a film sheet by simultaneously weighing a former, a cylindrical film sheet, and the input product weight by a load cell. No. 198906.

I have. However, when the object to be packaged is a powder such as flour or potato starch, there is a drop from the bag mouth to the bag bottom, so that it rises up at the time of charging and the accommodation becomes poor. If it takes a long time for the rising to stop, the downtime at the filling station increases, which necessarily reduces the packing capacity. The soared powder is discharged to the outside by the suction device. However, even if the amount of soaking in each bag is small, it can be ignored in proportion to the production amount. It is preferable to suppress as much as possible. In the weighing and packaging method described in Japanese Patent Publication No. 6-29043, a structure for quantitatively detecting a packaged object while holding a packaging bag is disclosed. Since the filling and the sealing of the bag mouth are performed on separate tables, the packing machine is enlarged, and the overall structure is complicated. In the latter type of pillow-type packaging apparatus described in Japanese Patent Application Laid-Open No. H11-198906, the filling and weighing of the product are performed simultaneously in the process of bag making.
