着させるという手順によってなされる。[Prior Art] In recent years, it has become common for ordinary households to store out-of-season items such as futons and blankets in a compressed state by putting them in wrapping bags and storing them in a compressed state. A process is performed in which an article is placed in a wrapping bag having a sheet as a base, the rim of the opening of the wrapping bag is sealed, and then the inside of the wrapping bag and the article is evacuated. In many cases, the process for sealing the rim of a packaging bag containing an item involves heating a heat-adhesive layer made of thermoplastic synthetic resin provided on the rim of the packaging bag to heat-seal it. This is done by the following procedure.

損なわれるということが多々生じていた。[0003] Conventionally, the process for sealing the rim of a packaging bag involves heating the heat-sealing layer by rubbing the rim of the packaging bag while pressing it with a heated household iron. There were many things. However, if you rub the mouth edge of the bag with an iron while pressing it, the heat-sealing layer provided at the mouth tends to wrinkle, and if such wrinkles occur, it will not be possible to seal the bag securely. It becomes difficult. And if the rim is not sealed in a reliable airtight state,
When the inside of the wrapping bag is evacuated and the item is compressed using external pressure, or after the item is stored in a compressed state, air enters through the incompletely sealed part of the opening, and the compression effect deteriorates over time. There were many cases where the equipment was damaged.

An object to be solved is to provide a heat fusion method capable of heating the edge of the edge and sealing it in a reliable airtight state without causing wrinkles on the edge.

付けて、上記重なり部を融着させるものである。[Means for Solving the Problems] The heat-sealing method of the invention as claimed in claim 1 is characterized in that hot air having a temperature that melts the heat-sealing layers is applied to an overlapping portion of the heat-sealing layers that are melted by heating and heat-sealed to each other. The overlapping portions are fused together by spraying.

While the air blowing unit is in contact with the overlapping part of the heat-sealing layers, the hot air is blown from the nozzle while moving the air blowing unit along the overlapping part to fuse the overlapping part.

より気密状態に確実に封止される。According to the first aspect of the invention, the hot air raises the temperature of the overlapping portions of the heat-sealing layers to a melting temperature and melts the overlapping portions, thereby thermally fusing the overlapping portions. According to the second aspect of the invention, the hot air blown from the air blowing unit hits the overlapping portion of the heat sealing layer, and heats and melts the overlapped portion of the heat sealing layer to thermally fuse the overlapped portion. Further, since the hot air only hits the overlapping portion of the heat sealing layer, there is no room for wrinkles to form in the overlapping portion. Claim 3
According to the invention, the rim of a wrapping bag for storing articles such as futons in a compressed state is reliably sealed in an airtight state by heat-sealing the overlapping portions of the heat-sealing layers.

る。In the sealing process, as shown in the figure, pin-shaped spacers 5 protruding from four locations around the slit-shaped nozzle 31 (see FIG. 3) of the air blowing unit 3 are attached to the members to be heat-sealed. Place it on the mouth edge 81 of the wrapping bag 8 and slowly slide it in the direction of the arrow Hot air H having a temperature that melts the deposited layer 82 is blown out. In this way, the hot air H blown out from the nozzle 31 of the air blowing unit 3 is transferred to the wrapping bag 8.
The mouth edge 81 of the base 83 hits the surface of the base 83 and the base 83
The heat-sealing layer 82 laminated and integrated on the back side of the heat-sealing layer 82 is heated, and the heated portion gradually shifts from one end of the heat-sealing layer 82 to the other end. Each portion leading to the other end sequentially reaches a melting temperature due to the heat and is thermally fused. After the hot air H is used to heat the heat-sealing layer 82, it escapes outward through the gap between the mouth edge 81 of the wrapping bag 8 and the air blowing unit 3, which is secured by the spacer 5. When heating at this time, by aligning the longitudinal direction of the slit-shaped nozzle 31 of the air blowing unit 3 with the length direction of the heat-sealing layer 82, the heating action of the hot air on the heat-sealing layer 82 will cause the heat-sealing layer to melt. Since the layer 82 covers a wide area, even if the air blowing unit 3 is moved quickly to speed up the transfer speed of the hot air blowing points, the hot air blowing time to each part of the heat sealing layer 82 will be longer, making it difficult to reliably blow the hot air. Since heat fusion is performed, there is an advantage that the sealing process can be performed quickly and reliably.

確実に行なわれる。When the sealing process is performed in this manner, the edge 81 of the wrapping bag 8, that is, the heat sealing layer 82, is not rubbed by the air blowing unit 3, so that the edge 81 and the heat sealing layer 82 are not rubbed against each other. There is no room for abrasions to form on 82, and a situation where the abrasions impair reliable sealing by heat sealing does not occur. As a result, the opening edge 81 of the wrapping bag 8 is reliably sealed airtight, and the futon A can be compressed by the subsequent exhaust treatment and the compressed state of the futon A can be maintained after the exhaust treatment. It will be done.

るという利点がある。[Effects of the Invention] As described above, the heat sealing method of the present invention prevents the situation where the sealing of the mouth edge of the packaging bag is incomplete due to the wrinkles generated in the heat seal layer. Less likely to occur. In addition, since the nozzle of the air blowing unit is slit-shaped, if the method of the present invention is performed with the longitudinal direction of the nozzle aligned with the longitudinal direction of the heat-sealing layer, the heating effect of the hot air on the heat-sealing layer will be Since the adhesive layer covers a wide area, even if the air blowing unit is moved relatively quickly, the time required to blow the hot air to each part of the thermal adhesive layer will be longer, resulting in reliable thermal welding. This has the advantage that the sealing process can be performed quickly and reliably.
