[0010]

As described above, in the conventional vertical filling and packaging machine, the filling material is divided into predetermined amounts by sandwiching the tubular film by the respective squeeze rollers. However, since the weight of the filler is added to the tubular film when the filler falls into the tubular film, the bulging state of the tubular film in the portion below each squeegee roller when the respective squeegee rollers are closed is It varies from time to time. Therefore, there is a problem in that even if the respective closing rollers are closed at a predetermined timing, the amount of the divided filler varies, and the quantitativeness of the divided filler cannot be increased to a certain extent or more.

In order to solve such a problem, it has been proposed to provide a molding plate for pressing the tubular film between each crawler roller and the heat sealing device. In this method, the side of the tubular film is pressed by the molding plate to control the bulge, and the tubular film is sandwiched by the respective squeeze rollers in this state, thereby making the amount of divided products constant. However, in this case, although the quantitativeness of the product is improved, it is necessary to stop the feeding of the tubular film in order to control the bulging of the tubular film with the molding plate, and therefore, one bag-filled product can be produced correspondingly. The production time per unit increases and the productivity decreases.

[0012] Therefore, an object of the present invention is to provide a vertical filling and packaging machine which can enhance the quantitativeness of products without lowering the productivity.

[0013]

In order to achieve the above object, a vertical filling and packaging machine of the present invention comprises a film feed roller for feeding a resin-made tubular film filled with a product downward, and the film feed roller.

The ironing mechanism includes a pair of first squeegee rollers rotatably and rotatably opposed to each other between the cylindrical films, and a pair of first squeegee rollers below the pair of squeegee rollers, and the cylinder films are opposed to each other. And the tubular films are rotatably opposed to each other, and the tubular film is kept at a predetermined position from the time when the pair of first digging rollers sandwich the tubular film. When it sent only away, and having a second squeeze rollers sandwiching the tubular film.

The predetermined distance is equal to the first pair of
In the vertical direction between the rotation center of the crawler roller and the rotation center of the pair of second crawler rollers, and the rotation center of the pair of first claw roller and the pair of second crawler rollers. The distance in the vertical direction from the center is divided by both when the tubular film is sandwiched by the pair of first squeegee rollers and the pair of second squeegee rollers in a state where the bulge of the tubular film is stable. The amount of the filler to be packed is arranged so as to be equal to the amount of the filler to be packed in the packaged product, and the tubular shape is provided between the pair of first squeegee rollers and the pair of second squeegee rollers. A molding plate that presses the side portion of the film to control the bulge of the tubular film may be provided.

Further, the product may be a fluid substance.

[0016]

In the vertical filling and packaging machine of the present invention constructed as described above, the tubular film filled with the product is sandwiched by the pair of first squeeze rollers, and the product is divided. Then, when each of the first squeeze rollers is rotated to feed the tubular film downward, an empty filling portion is formed in the tubular film. When the products are divided by the respective first squeeze rollers, the bulging state of the tubular film varies depending on the state of the product being put into the tubular film, and thus the amount of the divided products also varies.

Therefore, when the tubular films are fed by a predetermined distance from the time when each of the first squeegee rollers sandwiches the tubular film, a pair of second squeegee rollers provided below each of the first squeegee rollers. The tubular film is sandwiched by. When the tubular film is sandwiched by the respective second crawler rollers, the bulging state of the tubular film is also stable. For this reason, when the product is divided by the respective first squeeze rollers, if the product is excessively divided, the swelling of the tubular film is stabilized because the extra product is further divided by sandwiching the second squeeze rollers. Even if the feeding of the tubular film is not stopped for this purpose, the quantitativeness of the product is further enhanced.

Further, the distance in the vertical direction between the center of rotation of the pair of first squeegee rollers and the center of rotation of the pair of second squeegee rollers is set so that the swelling of the tubular film is stable and the pair of first squeegee rollers and the pair of first squeegee rollers. When the tubular film is sandwiched by the second squeegee rollers, the amount of the filler divided by the two is arranged so as to be equal to the amount of the filler to be packed in the packaged product. In the case where a molding plate that presses the side portion of the tubular film to control the bulge of the tubular film is provided between the first and second pair of the second toroid rollers, each of the second tongue rollers has a tubular film. The swelling of the tubular film is regulated by the molding plate with the film sandwiched. Then, when the tubular film is sandwiched by the respective first squeegee rollers, the shape of the tubular film between the respective first squeegee rollers and the respective second squeegee rollers becomes constant, so that the amount of the divided products becomes constant. Become. In this case, the side of the tubular film can be pressed by the molding plate when the feeding of the tubular film is stopped in the heat sealing process, the cutting process, etc. It is not necessary to stop the feeding of the tubular film, and the productivity of the bag packaged product is improved.
