After evacuation, the opening and the upper cylindrical bottom of the container filled with hamburger are pressure-bonded by the heat fusion iron 13 installed in the chamber, the chamber is opened, and the hamburger filled with 150 g of 6 rows Moved downward by 150 m / m with respect to one bag at a speed of 150 mm / 6 sec.

The previous process was repeated, but 6 rows of packaging could be made continuously with a sprocket with pawls without any lateral deviation. This resulted in 60 food bag containers per minute. Productivity also improved more than 5 times compared to conventional packaging equipment. Also, the packaging bag was completely welded at the four corners, and there was no leaky film bag container. Because of the use of films with different thicknesses, the hamburger shape of processed foods was maintained.
"Comparative Example 1"

In conventional wrapping machines, it is carried out when cylinders are wrapped with a device (Sanko machinery's high packer) that crimps the bottom with a single film and crimps the bottom, and then crimps the top of the bag and the bottom of the upper tubular container. In order to increase the productivity similar to that in Example 1, it is necessary to increase the capacity (equipment, personnel) by a factor of five, which increases the cost and the manufacturing cost.
In contrast, since the present invention has a plurality of rows for continuous packaging, the labor cost is low, the installation area, power, etc. are less than the production volume, and the manufacturing cost is low. In addition, the present invention can use two different films, and can produce a new product in both shape and quality.
