A lateral opening communicating with the upper part of the bag is provided at an appropriate dimension below the upper edge of the bag, and this opening is connected to the bag by narrowing the gap between the clamps that clamp both sides of the upper end of the bag. The bag can be easily opened by loosening the body or by suctioning the lower part of the opening with a suction cup, etc., and filling the bag with the packaged item through this opening. After filling, the bag is conveyed from the filling section into the vacuum chamber 1 with both upper ends of the bag being held by the clamp members, and the bag is placed below the clamped part into the vacuum chamber 1 by the clamps, and then the bag is held at the opening. The present invention relates to a vacuum packaging method in which air is received and deaerated from inside the bag, and then the opening is thermally bonded to an appropriate width.

る。Conventionally, in order to fill a bag made of synthetic resin film with items to be packaged and vacuum package them, both sides of the upper end of the bag, which has an opening at the upper end, are held between clamp bodies, and the interval between the clamp bodies is reduced. At the same time as the bag is slackened, the top and back sides of the bag are sucked by a suction cup, the top of the bag is opened, and the packaged items are filled into the bag through this opening.

本発明は、叙上の欠点を除去するためなされたもので、
以下、実施例図に基いて説明する。However, when vacuum packaging a bag filled with items to be packaged in this way, the top opening of the bag is vacuum degassed and then the opening is thermally bonded, so the bag is clamped between clamps. Since it is not possible to move the bag from the filling section into the vacuum chamber with the bag filled with the object to be packaged, the clamp body must be removed from the bag filled with the items to be packaged, and then the bag must be manually placed into the vacuum chamber. In this method, the bag is automatically transferred and clamped by a clamp body in a vacuum chamber, but in this case, a large number of vacuum chambers are required, and the disadvantage is that it requires manpower or is a very large device. are doing.
The present invention has been made to eliminate the above-mentioned drawbacks.
Hereinafter, explanation will be given based on embodiment figures.

。It has a bag bottom 1 at the lower end, and the both sides and the top are thermally bonded 2 to an appropriate width.
, 2 and 3 A horizontal notch opening 6 is cut in the upper part of one side 5 of a vertically long bag body 4 made of synthetic resin film. Both sides of the upper end of this bag body 4 are clamped by clamp bodies 9, 9 which run horizontally on a chain 8, and placed in the filling section 7 of a vertical automatic filling and vacuum sealing machine, and the gap between both clamp bodies 9, 9 is The notch opening 6 is made small by making the bag body 4 slack, and if necessary, by suctioning the lower part of the notch opening 6 provided on one side 5 of the bag body 4 with a suction cup 10. The filling part 7 is opened and the bag 4 is filled with the object 11 to be packaged.

口部６を介し真空脱気する。After that, the clamp body 9 is returned to its original position so that the interval between them is widened, and the suction by the suction cup 10 is released.
After closing the notch opening 6, by running the chain 8, the bag body 4 is placed in the vacuum chamber 12 while the upper ends of the bag body 4 are held between the clamp bodies 9, 9, and the clamp body 9 is moved. .

込開口部６の封緘を行うことができる。In this way, both sides of the upper end of the bag body 4 are held by the clamp body 9,
9, the bag 4 is placed in the filling part 7 of the packaged object 11.
The bag body 4 is continuously moved from the vacuum chamber 11 to the vacuum chamber 12, and the bag body 4 is continuously moved from the vacuum chamber 112 to the vacuum chamber 12, and the bag body 4 is filled with the packaged object 11 in the filling section 7 while the clamp bodies 9 are clamping both sides of the upper end of the bag body 4 outside the vacuum chamber 12. Subsequently, vacuum degassing is performed in the vacuum chamber 12 through the notch opening 6 in the bag body 4, and thermal bonding 14 with an appropriate width is performed at the position where the notch opening 6 is cut. The incision opening 6 of the body 4 can be sealed.

従つて、大量の袋体４による被包装物１１の真空包装を

な真空包装が可能となる。Therefore, the vacuum packaging of the items 11 to be packaged using a large amount of bags 4 can be carried out continuously, and also in one set of the filling section 7 and the vacuum chamber 11.
By hanging several bags 4 from the chain 8 at the same time, it is possible to carry out vacuum packaging automatically, and to reduce manpower. In addition, during the above-mentioned process, when the bag body 4 is being moved from the inside of the filling section 7 into the vacuum chamber 12, the movement of the bag body 4 is stopped, and the bag body 4 is positioned on the extension line of both ends of the cut opening 6. Auxiliary clamp bodies 15, 1 are attached to both sides of the body 4.
5, and both sides of the bag body 4 are held by auxiliary clamp bodies 15,
15, the lower edge of the notch opening 6, which has become sagging due to the filling of the packaged object 11, is pulled linearly, and at the same time, the lower edge of the notch opening 6 is pulled by the other surface 13 of the bag body 4. By thermally adhering the material at a plurality of locations, temporary attachment 16 is carried out within a range that does not interfere with vacuum degassing, making it possible to perform beautiful and perfect vacuum packaging with few wrinkles.
