Description

The present invention relates to a tomographic observation kit capable of inspecting the sealed state of a sealed portion formed by laminating and fusion-bonding two laminated films by observing the cut surface of the sealed portion.

Conventionally, while continuously feeding out a long laminated film, a vertical seal portion and a horizontal seal portion are formed by using a heat sealing means to form a bag, and the inside of the bag is liquid or viscous. An automatic filling and packaging machine that automatically fills and wraps the object to be packaged is widely used (Patent Document 1 and Patent Document 2).

Japanese Unexamined Patent Publication No. 8-301237 Japanese Unexamined Patent Publication No. 2006-248578

In such an automatic filling machine, the production conditions according to the packaging form are set by inputting numerical values for each item, but the production conditions are appropriate depending on the quality of the laminated film and the temperature and humidity at the time of production. Check the sealing condition of the vertical and horizontal seals of the package manufactured before the start of production by the automatic filling machine and every few hours after the start of filling, and produce based on the result. The conditions are being modified.

In the automatic filling machine, if the production conditions (set values) are not appropriate, wrinkles and foaming may occur in the vertical seal portion and the horizontal seal portion, and the wrinkles may become passages and the packaged object may leak out. If even one product with a defective seal is generated, a large number of products manufactured on the same line may be subject to disposal. Therefore, it is necessary to appropriately modify the production conditions as described above. There is.

An example of the conventional inspection procedure for the sealed state is shown below.
Step 1) Cut out a part of the seal part (vertical seal part and horizontal seal part) of the film of the package manufactured by the automatic filling machine.
Step 2) Place the film piece cut from the seal part on the mat, apply a blade such as a cutter at a right angle to the surface of the film piece, and move the blade using a ruler as a guide to cut quickly.
Step 3) One of the film pieces cut into two pieces is fixed on a glass plate with double-sided tape so that the cut end face faces upward.
Step 4) Place the glass plate on the stage of the microscope, adjust the position of the stage, and focus the microscope on the cut end face to take a picture.
Step 5) Display the photographed image using a personal computer or the like, and confirm whether the seal state of the seal portion is good or bad.

The above inspection is manually performed by the worker multiple times a day, which is very troublesome and requires cutting a small piece of film so that the cut surface is not crushed and is horizontal. It was dangerous because it required the skill of the operator and cut it with a cutter or the like.

Furthermore, since the inspection of the sealed state is usually performed at a place (office, etc.) different from the production site of the package, the sealed state is inspected, the appropriate production conditions are calculated from the result, and the filling and packaging machine is used. Before setting, it was necessary to go back and forth between the inspection site and the production site of the package many times, which took time and effort.

Therefore, in the present invention, a worker can inspect the seal state of the seal portion at the production site of a product such as a package, and anyone can easily inspect the seal state without requiring the skill of the worker. It is an object of the present invention to provide a tomographic observation kit that can be used.
