An apparatus and method for removing the supply pipe and applying a final seal to the bag mouth by final welding after 7 lashes to cause gas replacement are known as described in Japanese Patent Publication No. 57-29332 and the like. However, in order to expel the air inside the bag and replace it with inert scum using scum flush, it is necessary to insert the inert gas supply pipe to the bottom of the packaging bag. Powder is likely to fly up and cause a Jia shortage, and when packaging powder, castella cake, peanuts, etc., the supply pipe will not only pierce the packaged item and cause clogging or clogging, but also Cracks occur in the package, reducing the product value, and when the supply pipe is clogged or life-threatening, the amount of inert gas ejected changes, resulting in packages with defective gas replacement. There are drawbacks. Additionally, when inserting the supply pipe all the way to the top of the packaged item instead of all the way to the bottom of the packaging bag, the gas flush time for gas replacement must be lengthened, resulting in an increase in the amount of inert gas used and It becomes a time delay. There is also a method of inserting a supply pipe to the bottom of the package before filling the packaged material and then filling the packaged material around the pipe, but in that case, there is a limit to the size of the packaged material. . In addition, when filling the powder, the amount of loss due to scattering outside the bag increases as described above, and when the supply pipe is pulled out, the powder attached to the outer circumference of the pipe transfers to the main seal part, resulting in poor welding. resulting in defective packaging, etc.
Replacement with inert gas flash alone can cause various deficiencies and α
To overcome this deficiency, α, it is necessary to take measures for the packaged items, but there are some that cannot be overcome.

とし、本発明方法の目的とするものである。(Problems to be Solved by the Invention/Objectives of the Invention) The disadvantage of the conventional method described above is that good gas replacement cannot be achieved unless the gas supply pipe for injecting inert gas is inserted all the way to the bottom of the bag. This is due to the fact that there are some items to be packaged that cannot be inserted all the way to the bottom of the packaging bag in order to avoid packaging defects. Supplying liquefied inert gas that drips under its own weight, filling the packaged material on top of it, and further inserting an inert gas supply pipe above the packaged material with a length that does not penetrate the packaged material, It is an object of the method of the present invention to solve the problem of completely replacing the vaporized residue of the liquefied inert gas and the vaporized gas through the supply pipe.

る不活性ガス置換包装の汎用性を高めることができる。(Effects) In the method of the present invention, liquefied inert gas is dropped into the opened bag mouth of the bag 51a for packaging the object, the object C is filled thereon, and the object C is then punctured. The inert gas supply vibrator 14 is inserted into the opening of the bag at a height that does not allow the bag to enter the bag, and a temporary seal is applied. Gas replacement by seven lashes of inert gas is performed in parallel using the supply pipe 14, and the package g1a is vibrated by a bag loosening device 15 outside the packaging bag, and the inert gas is used to displace the package g1a.
This system promotes gas replacement by pushing air adhering to the top of the bag to the top of the bag and flushing the upper layer of the bag with inert gas, which not only eliminates the remaining amount of air but also
It is possible to reduce both the amount of liquefied inert gas dripped and the amount of gas flash, increase the replacement efficiency, and speed up packaging with inert gas replacement.
(Since it is not necessary to pass Eve 14 to the inner bottom of packaging bag a,
There is no risk of penetrating the previously filled packaged items and causing damage such as cracks to the packaged items, or causing the pipe itself to become clogged or bent by the packaged items,
In addition, since the inert gas supply pipe 14 is inserted later, there is no need to change the shape of the funnel, and even if the packaging bag a becomes longer, the height position of the inert gas supply pipe 14 when inserted into the bag is almost the same. Since there is no change, the versatility of inert gas replacement packaging using packaging bags for many items to be packaged can be increased.
また粉末包装についても、袋外への飛散損失をなくし、
包装作業の環境を良くすることが可能になる等の効果を
もつ。In addition, regarding powder packaging, we eliminate the loss of scattering outside the bag.
This has the effect of making it possible to improve the packaging work environment.
