Description

[Detailed description of the invention] [Industrial application field]

The present invention is a continuous band-shaped package usually called a hot pack, which is sealed with high-temperature noodle soup, sauce, and other appropriate liquid substances, divided into required amounts and sizes, and heat-sealed. The present invention relates to a cooling inspection method and apparatus for a continuous band-shaped package of a high-temperature liquid substance, in which a continuous band-shaped package of a high-temperature liquid substance is quickly cooled to a required temperature (room temperature) and simultaneously inspected for seal leakage at a heat-sealed part.

[Prior art]

Conventionally, packages filled with a high-temperature liquid substance called hot packs have a high temperature of approximately 85°C immediately after packaging, and if left in that state, it would be difficult to perform the subsequent boxing process, etc. Therefore, it was cooled to the required temperature (room temperature). As the cooling means, for example, as shown in FIG.
The individual packaging bodies 23 cut from the raw material are piled up in one place and allowed to cool naturally, or the individual packaging bodies 23 are cut from the heat sealing part 22 by the cutter 21 of the automatic packaging device 20 as shown in FIG. 7. They are placed in a pile or one by one on a net-like conveyor 24 and cooled to a required temperature (room temperature) through a cooling water tank 25. However, in the former case of the above-mentioned conventional cooling means, the high-temperature individual packages are simply piled up in a pile, so the heat dissipation effect is very poor, and the individual packages located in the center are kept at room temperature. Not only does it take a long time for the package to be cooled down, but the cooling is done gradually, which causes the growth of bacteria on the contents during the cooling process, reducing the shelf life of the package. In the latter case, cooling water speeds up the cooling time, but since the package is transferred while being placed on the net-like conveyor without being compressed, the contents themselves actively move within the package. The heat dissipation effect is further promoted by stirring, there is no seal leakage inspection at the heat sealing part, and depending on the type of packaging, some packages float on the water surface and the cooling effect is insufficient. When wiping off water droplets adhering to the surface of the package taken out of the water, it is necessary to automatically and reliably wipe the water droplets from the surface of the package, since each package is an individual package. There were some problems, such as the difficulty of doing it efficiently. In order to solve this problem, a prior invention of Japanese Patent Application No. 1982-236202 filed by the same applicant has been proposed. In the invention of this earlier application, a continuous band-shaped package filled with contents is passed through a cooling device continuously as it is, and a compressing action is applied to promote cooling, while at the same time inspecting for seal leakage. It is extremely superior compared to the example.

[Problem to be solved by the invention]

However, in the invention of the earlier application, the compressing action imparted when the continuous band-shaped package passes through the cooling device is a round bar-shaped compression roll, and the continuous band-shaped package is applied along the circumferential surface of the compression roll. The packaging body is only curved, which is insufficient for sufficient stirring of the contents, and there is a problem in that it does not lead to miniaturization of the cooling device or speed up of continuous packaging operations. .

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention conveys a continuous band-shaped package filled with a high-temperature liquid substance through a cooling medium, and during the conveyance, the continuous band-shaped package is subjected to a compressing action and partial bending. A continuous band-shaped package enclosing a high-temperature liquid substance, which is characterized in that it simultaneously imparts the following functions to the contents, thereby assisting fluid agitation of the contents to promote cooling, and simultaneously inspecting the sealing portion for seal leakage. A cooling inspection method for cooling, a cooling device for cooling a continuous strip-shaped package containing a high-temperature liquid substance as the content, and a cooling device for conveying the continuous package in a stretched state and in a zigzag pattern in the vertical direction within the cooling device. A continuous strip-shaped package encapsulating a high-temperature liquid substance, characterized in that the compression device is configured to apply partial bending to the continuous strip-shaped package. By applying a compressing action and a partial bending action to a continuous band-shaped package during cooling and transportation,
The contents can be fluidized and stirred more actively, thereby significantly accelerating cooling, making it possible to downsize the cooling device, and making it possible to accurately inspect seal leaks due to bending.

The cooling inspection device for a continuous strip package of the present invention having the above configuration forms a continuous strip package a that is continuously sealed by the automatic packaging device A and into which the content b is injected, and The body a is continuously introduced into the cooling device 1. In this cooling device 1, a continuous band-shaped package a is conveyed in a zigzag shape by a pressing device 2, that is, a guide member 2a,
For example, the contents are cooled to approximately room temperature by passing through cooling water. When conveyed under tension by the guide member 2a, the continuous band-shaped package a is partially dented by the rod-shaped member 3, and at the same time a compressing action is applied to the liquid contained therein. The contents b are moved and stirred inside each package. In other words, the successive individual packages are rolled up in the rotational direction It becomes bent in several places. By being in this bent state, the movement of the contents b starts from the end side in the advancing direction when it is rolled up, and when it is located at the top (the position indicated by the imaginary line), it is evenly distributed on the left and right sides. There is a movement of the contents b as shown in FIG. During these movements, because the rod-shaped member 3 is in a bent state with a portion being concave at multiple locations, turbulence occurs when the fluid moves, and a stirring action is inevitably imparted. It will become. Therefore, when the continuous strip-shaped package a passes through the cooling device 1, it is conveyed in a zigzag manner in the vertical direction, and during the conveyance, it is conveyed multiple times at the top and bottom positions by the pressing device, that is, the guide member 2a. Since the compressing action and stirring action are applied to the stored contents b at the same time, they are evenly stirred and cooled quickly. Then, during the above-mentioned conveyance, the pressing device 2
Applying compressing and bending effects to the continuous band-shaped package a by the guide member 2a is a harsh condition, and by applying these actions multiple times,
If the heat-sealed part for sealing the contents is incomplete, the contents b will leak from the sealing part, and this is visually inspected during transportation. The continuous band-shaped package a cooled by the above is
