Abstract

PURPOSE:To enable an item laminated with a thermoweldable resin to be used, by drilling a number of jet ports in a surface of a block of a heat sealer, and joining raw films while jetting air from the ports. CONSTITUTION:A number of jet ports 11 are drilled in a surface of a block 9 of a heat sealer, then while air is being jetted from the ports 11, and parts of raw films 4, 5 where joining should be done are placed between the stock 9 and the heat bar 10 and are heated with an air layer formed between the stock 9 and the film to weld the parts, so that thermoweldable laminated films may be joined. It is preferable that the surface of the raw films where thermoweldable resins 6, 7, 8 are laminated is opposed to the stock, the edges are engaged, a joining tape whose opposite surfaces are laminated with thermoweldable resin is placed between the engaged edges and the joining is carried out.

要件とされている。Heat-fusible laminate films are used for packaging films and packaging bags for packaging articles. Needless to say, packaging bags with packaging film have appropriate elasticity, toughness, flexibility, weather resistance, etc. that match the material and shape of the item to be packaged, and the inner surface is water and oil resistant. It is necessary that the outer surface has stain resistance and printability, and in particular, it is essential that the inner surface has heat-sealability.

のである。For this reason, a film whose inner surface is laminated with a heat-sealable resin such as polyethylene or polypropylene is used as a raw film for packaging films and packaging bags.

ムの幅が限定されていて、最大幅が１〜１５メ一トル程
度であるため上記要請に応えることができなかった。However, in recent years, it has become possible to produce heat-sealable laminate films with high tensile strength and tear strength, and as a result, there has been an increasing demand for packaging large-sized articles and large amounts of powder and granular materials. Of course, in order to do this, packaging films, films, and packaging bags must be made larger, but the current manufacturing technology for heat-adhesive laminate films limits the width of the product film, and the maximum width is 1 to 1. As the distance was approximately 15 meters, we were unable to meet the above request.

　　　　　掌張りとしなければならなかったのである。It may be possible to make a wide base film by splicing heat-sealable laminate films formed to the most appropriate width, but as already mentioned, heat-sealable laminate films used as packaging materials can only be used on the inner surface. Heat-sealable resin is laminated, and the outer surface is laminated with printable (non-thermal-sealable) synthetic resin, and although the inner surfaces of the film are heat-sealed together, the inner and outer surfaces are not bonded. from,
In the conventional technology, as shown in FIG.
I had to hold on to it.

この合掌張りの部分は比較的剥離強度が小さくて、製品

表面に突出するので、フィルムの使用範囲が著るしく限
定されるのである。This gassho tension part has a relatively low peel strength, and when tensile force is applied to the product wide film, brittle peeling occurs in this part, so even if a material film with high tensile strength is used, the product wide The film has a low tensile strength and cannot be used as a large packaging material. Furthermore, since the palms of this wide film protrude from the surface of the film, the range of use of the film is severely limited.

ところで従来の熱熔着性ラミネートフィルムの接合が上
に述べた様に合掌張りに限られたのは、第一にはフィル

ー２又は受台３と接する面に熱熔着性樹脂がラミネート
されていると、これが受台３等に熔着してしまって、連
続的熔着作業が不能になることによるのである。By the way, as mentioned above, the joining of conventional heat-sealable laminate films has been limited to the gassho-gluing method, primarily because the films are only heat-sealed to each other on their inner surfaces. To attach the film, as shown in Fig. 4, that part is sandwiched between the heat bar 2 and the pedestal 3, so the surface of the film that comes into contact with the heat bar 2 or the pedestal 3 is laminated with thermofusible resin. This is due to the fact that this welds to the pedestal 3, etc., making continuous welding work impossible.

る。In the present invention, a large number of blowholes are perforated on the surface of the pedestal, and by blowing out air from these holes, the film can press the pedestal without coming into contact with it. This allows the films to be welded with their laminated surfaces facing the pedestal, for example, by butting the edges of two films to be joined and applying heat to one side. A tape laminated with a meltable resin is placed over this area and welded. In other words, by doing this, the product wide film has nothing protruding from the joint, and is in a flat state, and moreover, this part is stronger than the original film.

実施例 以下本発明を図示の実施例に基づいて具体的に説明する

ら空気を噴出するようになっている。This shows an example of joining the parts by heat welding.
In the figure, 4 and 5 are original films. These raw films 4 and 5 are similar to the usual heat-sealable laminated film for packaging shown in FIG. 4, and are made by laminating heat-sealable resin 6.7 on the inner surface of a base film made of nylon, tetron, etc. A heat-fusible resin 8 is laminated to the bonding margin on one side of a heat-fusible laminate film. Reference numeral 9 is a pedestal, and 10 is a heat bar. These are the main parts of the so-called heat sealer, which heat the parts of the heat-adhesive laminate film that are to be joined by sandwiching and pressing them.
The heat-fusible resins 6 and 8 are melted, and the heat bar 10 is heated to an appropriate temperature, and the force pedestal 9 has a large number of blowholes 11 perforated on its surface. It is designed to blow out air.

原反フィルム４と５とを接合するには、第１図に示した
様に、該フィルムの内面を受台９に向けて両者の接合代
の部分を重ね合わせ。In order to join the raw films 4 and 5, as shown in FIG. 1, the inner surfaces of the films are directed toward the pedestal 9, and the parts of the two films to be joined are overlapped.

一方ヒートバ−ＩＯは適宜な温度に加温し、噴気口１１
からは空気を噴出させつつ、両者の間に上記重ね合わせ

なり。On the other hand, the heat bar IO is heated to an appropriate temperature, and the
The overlapping portion is sandwiched between the two while blowing out air. Then, the raw films 4 and 5 are heated, and the heat-sealable resins 6 and 8 in those areas become molten.

然して熔着するのである。Naturally, it melts.

ところでこの場合において、受台９の表面からは空気が

ことがないから、原反フィルム４と５との接合が可能と
なるのである。By the way, in this case, since air is blown out from the surface of the pedestal 9, a thin film layer of air is formed between the heat-sealable resin 7 and the pedestal 9, and the heat-sealable resin 7 is received. There is no contact with the stand 9. Therefore, although the heat-fusible resin 7 is also heated and becomes molten, it does not weld to the pedestal 9, so that the raw films 4 and 5 can be joined.

尚、上記において噴気口１１から噴出する空気は作業能

の材料として使用され翫 るのである。In addition, in the above, it is preferable that the air blown out from the blowhole 11 be hot air rather than cold air from the point of view of work efficiency.
Also, although the raw films 4 and 5 have been described as if they were separate films, they may of course be both ends of the same raw film.
In this case, the product wide film becomes a cylindrical body and is used as a material for packaging bags.

用テープである。Figure 2 shows an example of butting together the joining ends of raw films and joining them via a joining tape. In Figure 1, numerals 12 and 13 are the original films, and 18 is the joining tape. .

たものである。The raw films 12 and 13 are similar to the usual heat-sealable laminate film of this type shown in FIG. 4, and are made by laminating a heat-sealable resin onto a base film such as nylon or Tetron. The joining tape 18 is made by laminating a heat-fusible resin on both sides of a base film having an appropriate width.

原反フィルム１２と１３とを接合するには、第２図に示
すように両者の端縁を突き合わせ。To join the raw films 12 and 13, their edges are butted together as shown in FIG.

い様にするのであるが。Reference numerals 14 and 15 are pressure rollers, 16 is a drive roller, and 17 is a winding drum. yK anti-film 12.13
The bonding tape 18 is fed out at a constant speed by the drive roller 16, passed between the heat bar 10 and the pedestal 9, heated, and further compressed by the pressure rolls 14 and 15 for bonding. It becomes a weldable laminate film and is wound around the winding drum 17. Of course, in this case, air is blown out from the blowhole 11 of the pedestal 9 to prevent the joining tape 18 from coming into contact with the pedestal 9.

望ましいのである。Since the joining tape 18 is still in a heated state even when it reaches the pressure roll 14.15, the pressure roll 14 (which does not necessarily need to be rotated) is also provided with a blow hole 19 on its surface. It is desirable that the objects do not come into contact with this.

Therefore, it is possible to use a raw film with heat-sealable resin laminated on the surface facing the pedestal6.
