Abstract

PURPOSE:To prevent a fusion refuse of a film from attaching to a cutter holder by positively lowering the temperature of the cutter holder which is a part for holding a heat cutter. CONSTITUTION:A pressure applying face 11b is formed at the lower end of a pair of hot plates 11 of a thermal adhesion heater unit, wherein a heater 12 is formed in a circular rod to be mounted in an installation hole 11a which is formed inside the hot plates 11 and whose cross section is circular. A cutter holder 13 is mounted below the hot plates 11 and held so that it is interposed between both hot plates 11 from both sides. A cut 13b for admitting a heat insulating chip 16 and a lengthwise cooling medium path 13 are formed on the upper face of the cutter holder 13, while a groove 13c opening downward is formed at the center. A heat cutter 14 is placed at a medium part of the pressure applying face 11b and admitted into the above groove 13c. When a film F is to be adhered and fused, a fusion refuse is generated, but the cutter holder 13 is kept at a lower temperature than a melting temperature of the film F by blowing cooled air to the cooling medium path 13a so that the fusion refuse will not attach to and deposit on the cutter holder 13.

（行なわれている。BACKGROUND OF THE INVENTION In the packaging of prior art articles, particularly in the packaging of individual articles, thermal bonding using thermoplastic plastic sheets or plastic films (hereinafter simply referred to as films) is widely used.

断することができる。Thermal bonding can be performed by pressing a heated hot plate against the bonded portion. That is, after heating a hot plate formed to match the shape of the adhesive part of the film to a predetermined temperature, the pressurized surface of the hot plate is pressed against the adhesive part, thereby melting the adhesive part and thermally bonding it. In addition, some thermal bonding devices are equipped with a heat cutter that is close to the pressure surface and parallel to the pressure surface. It is possible to press the film and melt-cut the film through a cutting part parallel to the adhesive part.

問題があった。Problems to be Solved by the Invention When using the above conventional technology, when the adhesive part of the film is melted on the pressurizing surface of the hot plate or when the film is cut by a heat cutter, molten residue of the film is generated and the heat cutter There was a problem in that the appearance of the bonded part including the fused part became unsightly because the melted debris adhered and accumulated on the parts holding the parts and the like.

これは、ヒートカッタの保持部分の温度が、フィルムの
溶融温度以上に上昇してしまうのが原因である。This is because the temperature of the holding portion of the heat cutter rises above the melting temperature of the film.

にある。Therefore, in view of the problems of the prior art, an object of the present invention is to actively lower the temperature of the cutter holder, which is the holding part of the heat cutter, to prevent molten film residue from adhering to the cutter holder, and to prevent the adhesion part from adhering to the cutter holder. To provide a heater unit for thermal adhesion that can be finished with good appearance.

る。Means for Solving the Problems The structure of the present invention for achieving the object includes a hot plate having a pressure surface at the lower end, a cutter holder attached to the lower part of the hot plate and provided with a cooling medium passage, and a cutter holder whose lower end is heated. The gist thereof is to include a heat cutter attached to the cutter holder so as to protrude from the pressure surface, and a heater that heats the hot plate.

また、熱板の側面に予熱板を付設してもよいものとする
。Further, a preheating plate may be attached to the side surface of the heating plate.

作用 この構成によるときは、熱板の加圧面をフィルムに圧接
すれば、フィルムは、加圧面によって押圧される部分が

、フィルムの溶断を併せ行なうことができる。なお、ヒ
ートカッタの加熱は、熱接着の終了後、大電流を通電す
ることにより、瞬時的に行なうのがよい。Function: With this configuration, when the pressure surface of the hot plate is pressed against the film, the portion of the film pressed by the pressure surface melts, making it possible to thermally bond the film. At this time, since the lower end of the heat cutter protrudes from the pressurizing surface, by raising the temperature of the heat cutter to a temperature higher than the melting temperature of the film, the film can also be cut by fusing. The heat cutter is preferably heated instantaneously by applying a large current after the thermal bonding is completed.

フィルムの溶断時には、溶融かすか発生するが、このと
き、カッタホルダの冷却媒体通路に冷却空気などを通す
ことにより、カッタホルダの温度をフィルムの溶融温度
より低く抑えることができ、したがって、溶融かすかカ
ッタホルダに付着するおそれかない。When the film is melted, molten scum is generated, but at this time, by passing cooling air etc. through the cooling medium passage of the cutter holder, the temperature of the cutter holder can be kept lower than the melting temperature of the film, so that molten scum does not adhere to the cutter holder. There's no chance of it happening.

予熱板を取り付けた場合は、フィルムが厚くて剛いとき
でも、予熱板からの放熱により、予熱板の近傍のフィル
ムを軟化させることができるから、熱接着の終了後、熱
板をフィルムから離した際に、接着部が不用意に離れた
りするおそれを有効に排除することができる。If a preheating plate is attached, even if the film is thick and stiff, heat radiation from the preheating plate can soften the film near the preheating plate, so it is easy to separate the heating plate from the film after thermal bonding is completed. When doing so, it is possible to effectively eliminate the possibility that the adhesive portion may come apart inadvertently.

第１図の実線）。Now, let us consider a case where the pressurizing surfaces 11b, llb of the unit and the cushioning material 51 are sufficiently separated, and the unit is lowered by interlocking with a lifting device (not shown) so as to sandwich the film FSF. At this time, the holding member 18.18 first comes into contact with the films F, F, and the holding member 18.18 sandwiches the films F, F between it and the cushion material 51, and F can be held mechanically. Note that at this time, the presser member 18
．． 18 moves upward against the compression spring 18b,
The lower end of the cushion material 51 can be slightly recessed and the films F can be held with a predetermined force (

うなことは全くない。Here, when the last holding member 18.18 is released, the mechanical holding of the film FSF is released, so if the films F and F are thick and loose, an excessive force is applied to the adhesive part F2. Peeling is likely to occur at the bonded portion F2. However, here, since the preheating plate 15 is present, the film F in the vicinity thereof becomes soft due to heat dissipation from the preheating plate 15.
Therefore, even if the holding members 18.18 are separated from the films F, F, there is no possibility that the films F, F will be peeled off from the adhesive portion F2.

く仕上げることができるという優れた効果がある。As described in detail, according to the present invention, by forming a cooling medium passage in the cutter holder, the temperature of the cutter holder can be suppressed to below the melting temperature of the film, so that molten residue of the film does not adhere to the cutter holder. This has the excellent effect of effectively preventing this and making it possible to finish the bonded portion of the film in an attractive manner.

また、溶融かすか付着しないため、ユニットの所要清掃
頻度が格段に少なくて済むという実用的な効果もある。Furthermore, since melted debris does not adhere, there is a practical effect that the frequency of cleaning of the unit is significantly reduced.
