The present invention relates to a packaging and filling machine to produce a packaging container for beverages such as cow's milk juice and mineral water, and fluid food and the like.
A web-shaped laminated packaging material is used for packaging liquid foods and the like. The packaging container for beverages such as cow's milk, juice and mineral water, and fluid food and like is obtained, for example, from the web-shaped packaging material made of fibrous substrate (for example such as paper)/plastic lamination with pleat lines, printed with an appearance design.
The web-shaped laminated packaging material is formed into a tube shape by longitudinal sealing in the longitudinal direction, the food is filled in the tube-shaped packaging material, and the tube-shaped packaging material is laterally sealed in the transverse direction, formed into a primary shape with a pillow form, cut at an individual container, folded along pleat lines, then formed into a final shape by folded along pleat lines. As the final shape, there includes shapes such as a brick, an octagonal column and tetrahedron.
In a roof-shaped paper packaging container, the paper packaging material printed with the product appearance design on the surface is cut into a predetermined shape, blanks sealed in the longitudinal direction of the container are obtained, after the bottom of the blanks is sealed in a filling machine, beverages such as cow's milk and juice are filled from a top opening, the upper part is sealed, and thus the product container is obtained.
In another packaging and filling machine, the laminated packaging material with pleat lines is cut into a predetermined shape, blanks sealed vertically in the longitudinal direction of the container are obtained, the lid portion of the blanks is formed by injection molding, foods are filled from the opening at the bottom portion of the blanks, and the bottom portion is sealed.
The laminated packaging material with pleat lines printed with the product appearance design is produced wound in a reel shape, in a manufacturing plant of the packaging material, by laminating a process for laminating fibrous layer of web-shaped paper and the like, aluminum foil, and plastic film by means of extrusion laminating and the like, by a printing process, prior to, in the middle of, or after the laminating process, for printing with the appearance design and by a crease process for providing pleat lines with the packaging material.
The reel shape laminated packaging material is transferred from the manufacturing plant of the packaging material to a food factory, with which the packaging and filling machine is equipped. In the packaging and filling machine, laminated packaging materials are connected with each other between the prior and subsequent reels, in addition, a protecting tape for the end surface as an auxiliary packaging material is heat sealed.

The reel shape laminated packaging material is equivalent to several tens of thousands of or a hundred and several tens of thousands of containers. When various kinds of containers are produced in small quantity, a large number of used reels are left, causing the problem of the increase of waste materials and the growth of an environmental load.
Producing the reel shape laminated packaging material in the manufacturing plant of the packaging material at high speed and effectively allows the cheaper production. A packaging and filling system for producing various kinds of containers in small quantities using the cheap reel shape laminated packaging material is necessary.
It is an object of the present invention to provide the packaging and filling system which uses the reel shape laminated packaging material effectively, reduces the waste amount of the used reel, and can reduce the environmental load.
It is a further object of the present invention to provide the packaging and filling system which produces various kinds of containers in small quantities using the cheap reel shape laminated packaging material.
