Abstract

PURPOSE:To improve a cooling efficiency and perform an inspection for leakage of a sealing part of a continuous belt-shaped package by delivering the continuous belt-shaped package to pass through a cooling medium while applying a pressure deflection and partially folding forces thereonto. CONSTITUTION:A continuous wrapping band (a) is formed by means of an automatic wrapping apparatus A and has individual bags into which contents are charged and between which heat-seals are provided. The belt-shaped package (a) is continuously introduced to a cooling device 1 wherein the package is transported along a zigzag path of a pressure deflecting device 2. During transportation of the package along the path, a bar member 3 of the pressure deflecting device 2 exerts a depressing or recessing force on a part of the package to thereby allow the fluid contents in the individual bags to be moved and agitated therein and cause the package to be folded at plural portions. While the package passes through the cooling device, the contents in the individual bags of the package are simultaneously subjected to agitating and pressure deflecting effects so as to be uniformly stirred and rapidly cooled. If there exists any leakage of the contents from each bag due to imcomplete heat seals, these deficiencies can be visually checked during a delivery process.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention is a method for enclosing high-temperature noodle soup, sauce, liquid substances such as currency, etc., which are usually called hot bags, according to the required amount and size. Cooling of continuous strip-shaped packages for high-temperature liquid substances that are heat-sealed in sections are quickly cooled down to the required temperature (room temperature) immediately after automatic packaging, and at the same time, seal leakage inspection at the heat-sealed part is performed. 11J
It relates to inspection methods and equipment.

[Prior Art 1 Conventionally, a package containing a high-temperature liquid substance called a hot pack has a high temperature of about 85°C immediately after packaging, and if left as is, it will be difficult to carry out during the subsequent packaging process etc. Since this would make the work difficult, it was cooled to the required temperature (room temperature).

As a cooling means, for example, as shown in FIG. 6, the individual packages 23 cut from the heat-sealed portion 22 by the cutter 21 of the automatic packaging device 20 may be piled up in a pile and cooled naturally; Automatic packaging machine @20 as shown
The individual packages 23 cut from the heat-sealed portion 22 by the cutter 21 are placed in a pile or one by one on a net-like conveyor 24 in a required number and cooled to a required temperature (room temperature) through a cooling water tank 25. Ta.

However, in the former case with the above conventional cooling means,
Because the high-temperature individual packages are simply piled up in a pile, the heat dissipation effect is very poor, and it takes a long time for the individual packages located at the core of the RP to cool down to room temperature. However, since the cooling was done gradually, there was a problem that the growth of bacteria in the contents was promoted during the cooling and the shelf life of the package was shortened. Although it takes time, the contents themselves are actively transferred within the package because the package is transferred while being placed on the net-like conveyor without being compressed. 1l
W1. The cooling effect may be insufficient because the product is stirred to further promote its effectiveness, there is no seal leakage inspection at the heat-sealed part, and depending on the type of packaging, some packages float on the water surface. In addition, when wiping off water droplets on the surface of a package taken out of water, since each package is an individual package, this can be done automatically and reliably with high efficiency. There was a problem with the hat, which was difficult to do.

In order to solve this problem, a patent application filed in 1983 by the same applicant was filed.
An earlier invention of No. 2-236202 has been proposed. In the invention of this earlier application, 3! ! It is extremely superior to the conventional example in terms of passing the continuous continuous package as it is through the cooling device continuously, applying a compressing action to accelerate cooling, and at the same time inspecting for seal leakage. -ing

(Problem to be Solved by the Invention 1) However, in the invention of the earlier application, the compressing action provided when the continuous band-shaped package passes through the cooling device is a round bar-shaped pressing roll, and this pressing The continuous band-shaped packaging body is only curved along the circumference of the roll, which is insufficient to provide sufficient Wl for the contents.In particular, miniaturization of the cooling device and speed of continuous packaging work are insufficient. The problem is that it does not lead to improvements.

[Means for Solving the Problems 1] In order to solve the above-mentioned problems, the present invention conveys a continuous band-shaped package containing a high-temperature liquid substance through a cooling medium, and during the course of conveyance, the continuous band-shaped package Simultaneously imparts a flattening action and a partial bending action to the material, thereby assisting fluid agitation of the contents and promoting cooling;
A cooling inspection method for a continuous band-shaped package containing a high-temperature liquid substance, which is characterized by simultaneously inspecting the seal portion for seal leakage, and a cooling f! J device, and a pressing device that imparts a compressing action to the continuous package while transporting the continuous package in a stretched state and in a zigzag shape in the vertical direction in the cooling device, and the compacting device applies a compressing action to the continuous package. The present invention provides a cooling inspection device for a continuous band-shaped package containing a high-temperature liquid substance, which is characterized by having a structure that partially bends the body, and which applies a compressing action to the continuous band-shaped package during cooling and transportation. By imparting a partial bending action to the content, the fluid agitation (gamma) of the contents is carried out more actively, thereby significantly accelerating cooling, making it possible to downsize the cooling device, and
This allows for accurate inspection of seal leaks due to bending.

These guide members 2a are disposed inside the cooling 8 and 1 in a vertically substantially parallel manner, and in the illustrated embodiment, five guide members are disposed in the upper part and four guide members are disposed in the lower part, and these guide members 2a
The continuous band-shaped package a is conveyed in a zigzag pattern up and down inside the cooling device. Further, if necessary, a pressing auxiliary roll 6 may be provided in contact with the guide member 2a disposed at the upper part. This pressing auxiliary roll 6 can set the contact pressure with the guide member 2a arbitrarily, and although not shown in the drawings, a pressure R such as a spring can be used to adjust the pressure.

18, a plurality of air pipes 9 are disposed facing each other, and a J-ar blowing hole 9a is provided on the opposing surface side, and the continuous band-shaped package a passes between these air vias 9. In the figure, reference numeral 10 is a tension roller provided on the inlet side of the cooling device 1, and 11 is a guide roller provided on the exit and inlet sides. And, to the automatic packaging device, there are used in the membrane, 12 is a cylindrical forming guide for the strip film a', 13 is a content supply nozzle, 14 is a set of sealing rolls, and 15 is a horizontal The seal roll, 16 is a heat sealing part, a'' is one package, and b is the contents.

[Description by vJ 1 The cooling inspection device for continuous strip-shaped packages of the present invention having the above-mentioned configuration forms a continuous strip-shaped package a that is continuously sealed by automatic packaging machine A and injected with contents. Then, the continuous strip-shaped package 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 manner by a pressing device 2, that is, a guide member 2a, and its contents are cooled to approximately room temperature through cooling water, for example.

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 contents stored therein. Materials are moved and agitated within each individual 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, when rolling up the contents, the movement of the contents starts from the pant side in the advancing direction, and when it is at the top (position indicated by the imaginary line), the left and right sides are evenly spaced. There is a movement of the contents as shown in FIG. During these movements, since the rod-shaped member 3 is in a bent state with a portion being concave in multiple places, turbulence occurs when the fluid moves, and a stirring action is inevitably applied. be. Therefore, when the continuous strip-shaped package a passes through the cooling device 1, it is conveyed in a zigzag pattern in the vertical direction, and during the conveyance, it is stored in the vertical position several times by the compression device, that is, the guide member 2a. Since the contents are compressed and stirred at the same time, they are stirred evenly and cooled quickly.

During the transportation process, the guide member 2a of the compression device 2 applies compression and bending to the continuous band-shaped package a under severe conditions, and these are applied multiple times. Therefore, if the heat sealing part for sealing the contents is incomplete, the contents will leak from the sealing part, and this is visually inspected during transportation.

The continuous strip-shaped package a cooled by the above is conveyed from the exit side of the cooling W device 1 via the squeezing roll 7 while removing moisture adhering to its surface, and then air-dried [
