DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a filling apparatus and a packaging material.
BACKGROUND ART
Conventionally, brick-shaped packaging containers used for carrying liquid foods such as milk and soft drinks have been manufactured to a manner into which a web-like packaging material is first formed in a tubular shape, and then into a final shape while charging a liquid food therein.
In detail, the packaging material is first formed into a tubular shape by sealing it in the longitudinal direction to obtain a tubular packaging material, and the obtained tubular material is continuously transferred downward while a liquid food is supplied into it from its top. Then, while both sides of the tubular packaging material are supported by sealing jaws, the tubular packaging material is sealed laterally with a prescribed spacing to obtain a series of sealed compartments each of which has a rectangular shape such as a pillow or a bag.
In the next step, the tubular packaging material is cut at the portions corresponding to the lateral seals (hereinafter referred to as "lateral seal portion") and separated to obtain a plurality of finished packaging containers each of which contains a prescribed amount of liquid food.
In the case of gable-top containers, the packaging material is first cut into pieces of a predetermined shape which are sealed lengthwise to form a hollow column with a square cross-section. Subsequently, the bottom part of the column is shaped by a forming machine to obtain a box, and the top part is sealed after the liquid food is charged into the box, thereby forming a complete packaging container.
In a filling apparatus, a wide variety of liquid foods are filled in various packaging containers of different shapes and of different materials. In order to accommodate these varied conditions, the operator of the filling apparatus must input into the input unit of the filling apparatus both package information corresponding to the packaging material and liquid information corresponding to the liquid food.
When a roll of packaging material is loaded on the filling apparatus, the operator sets the operating conditions of the apparatus according to the specifications of the packaging material, while making records of the specifications of the packaging material and the liquid information, while adjusting sealing time, sealing temperature, and sterilization conditions.
Thus, a particular packaging container which contains a specified liquid food in a specified packaging material will be prepared.
However, it is very cumbersome to operate the input unit of the conventional filling apparatus. It is required not only to specify the packages material and the liquid food by inputting packaging material information and liquid information to the input unit so as to set a filling process program corresponding to the packages material and the liquid food, but also to adjust the operating conditions by inspecting the shape of completed packages even when the same packages material is to be used, since the material differs slightly in each lot.
Furthermore, it is difficult to adapt to complaints about products and to guarantee the product quality when conventional packaging materials are used, because it is impossible to identify the packaging container from the packaging material used or to trace its distribution route.
An object of the present invention is to overcome the aforementioned problems of the conventional apparatus and to provide a filling apparatus and packaging materials which can simplify the operation of the input unit while achieving accurate filling of packaging containers with liquid foods.
DISCLOSURE OF THE INVENTION
For achieving the above objects, the filling apparatus of the present invention comprises a read-out unit for reading out packaging material information regarding a packaging material from a magnetic recording medium layer formed on the packaging material, a sealing unit for sealing the packaging material, a filling unit for charging a liquid into the package and a memo
