従来、フィルムを溶断する溶断装置として、フィルムに熱および圧力を与える溶断刃によって、フィルムを溶着しつつ切断する装置が広く普及している。例えば、特許文献１（特開２００６−３０６４４５号公報）に開示されている溶断装置では、繰り返し使用による溶断刃の切断性の劣化を抑制するため、溶断刃の材料として、セラミックである金属複ホウ化物と、Ｆｅ（鉄）、Ｃｒ（クロム）、Ｍｏ（モリブデン）、Ｎｉ（ニッケル）、Ｗ（タングステン）等の金属とを合わせて焼き固めた、いわゆるサーメット（Ｃｅｒｍｅｔ）合金を使用して成形されている。   2. Description of the Related Art Conventionally, as a fusing device for fusing a film, a device for fusing and cutting a film with a fusing blade that applies heat and pressure to the film has been widely used.

（２−３―４−２）溶断刃５３
第１シールジョー５１ａの第１穴５１７内には、溶断刃５３が設けられている。以下、溶断刃５３について図４及び図５を参照しながら説明する。 (2-3-4-2) Fusing blade 53
A fusing blade 53 is provided in the first hole 517 of the first seal jaw 51a. Hereinafter, the fusing blade 53 will be described with reference to FIGS. 4 and 5.

図４は、刃先側から視た溶断刃５３の斜視図である。また、図５は、シールジョー５１の断面図である。図４において、溶断刃５３の先端部分は、長手方向に沿って三角波状の刃先５３ａが形成されている。刃先５３ａは、その先端側から視ても正面側から見ても三角波状を成す、複雑な形状である。また、図５に示すように、溶断刃５３の先端面は、平面ではなく第１シール面５１６と同じく半径Ｒの円弧面である。なお、溶断刃５３の先端面は、第１シール面５１６から距離ｄだけ突出している。この溶断刃５３の先端面とは、刃渡り方向に波形に成形された刃先の先端が描く稜線を含む仮想面のことであり、刃の厚み方向に沿って半径Ｒで湾曲している。   FIG. 4 is a perspective view of the fusing blade 53 viewed from the blade tip side. FIG. 5 is a cross-sectional view of the seal jaw 51. In FIG. 4, the tip portion of the fusing blade 53 is formed with a triangular wave-shaped blade edge 53 a along the longitudinal direction. The blade edge 53a has a complicated shape that forms a triangular wave shape when viewed from the front end side or the front side. Further, as shown in FIG. 5, the front end surface of the fusing blade 53 is not a flat surface but an arc surface having a radius R like the first seal surface 516. Note that the front end surface of the fusing blade 53 protrudes from the first seal surface 516 by a distance d. The front end surface of the fusing blade 53 is a virtual surface including a ridge line drawn by the front end of the blade tip formed in a waveform in the blade crossing direction, and is curved with a radius R along the thickness direction of the blade.

従来、溶断刃５３の材料には、サーメット合金が使用されていたので、材料が高価な上に、溶断刃５３の複雑な刃先形状へ加工するために必要なリードタイムが長く、コスト増加の要因であった。   Conventionally, a cermet alloy has been used as the material for the fusing blade 53, so that the material is expensive and the lead time required to process the fusing blade 53 into a complicated cutting edge shape is long, which is a factor in increasing costs. Met.

本実施形態の溶断刃５３は、従来の問題点を解消すべく、材料には、加工性に優れた汎用の高速度工具鋼を採用している。但し、特許文献１の段落［００４２］でも開示されているとおり、高速度工具鋼で製作された溶断刃の耐久性は、サーメット合金で製作された溶断刃より劣る。それゆえ、本実施形態では、溶断刃５３の耐久性を高めるため、刃先５３ａを含む先端部分に表面処理が行なわれ、先端部分の硬さが所定値以上になるように調整されている。   The cutting blade 53 of the present embodiment employs a general-purpose high-speed tool steel excellent in workability as a material in order to eliminate the conventional problems. However, as disclosed in paragraph [0042] of Patent Document 1, the durability of the cutting blade made of high-speed tool steel is inferior to that of a cutting blade made of a cermet alloy. Therefore, in the present embodiment, in order to improve the durability of the fusing blade 53, the surface treatment is performed on the tip portion including the blade edge 53a and the hardness of the tip portion is adjusted to be equal to or higher than a predetermined value.

具体的には、溶断刃５３の先端部分に、窒化処理、またはショットピーニング処理、または窒化処理およびショットピーニング処理の複合処理が行なわれ、先端部分の硬さがＨｖ１０００以上になるように調整されている。なお、未処理では、先端部分の硬さはＨｖ８００程度である。   Specifically, nitriding treatment, shot peening treatment, or a combined treatment of nitriding treatment and shot peening treatment is performed on the tip portion of the cutting blade 53, and the hardness of the tip portion is adjusted to be Hv1000 or more. Yes. In addition, the hardness of the tip portion is about Hv800 when not processed.

また、図４及び図５に示す刃先５３ａの最先端の厚みｔは、０．０５ｍｍ以上、０．２ｍｍ未満に設定している。さらに、刃先５３ａの最先端の曲率半径は、従来の寸法を踏襲して、半径ｒは、０．０５ｍｍ以上、０．２ｍｍ未満に設定している。   Moreover, the most advanced thickness t of the blade edge 53a shown in FIGS. 4 and 5 is set to 0.05 mm or more and less than 0.2 mm. Further, the cutting edge radius of the cutting edge 53a follows the conventional dimensions, and the radius r is set to 0.05 mm or more and less than 0.2 mm.

出願人は、高速道工具鋼の日本工業規格におけるＳＫＨ５１で溶断刃５３を製作し、先端部分に窒化処理を行なった第１サンプルＳ１、先端部分にショットピーニング処理を行なった第２サンプルＳ２、先端部分に窒化処理およびショットピーニング処理の複合処理を行なった第３サンプルＳ３、及び先端部分になんら処理を行なっていない第４サンプルＳ４について、同じフィルムを同じサイクルでシールするという条件で耐久性試験を行なった。なお、第１サンプルＳ１及び第３サンプルＳ３の先端部分の硬さはＨｖ１１００以上、第２サンプルＳ２の先端部分の硬さはＨｖ１０００以上、第４サンプルＳ４の先端部分の硬さは９００未満である。   The applicant manufactured the cutting blade 53 with SKH51 in Japanese Industrial Standards for highway tool steel, the first sample S1 subjected to nitriding treatment on the tip portion, the second sample S2 subjected to shot peening treatment on the tip portion, the tip The durability test was performed on the condition that the same film was sealed in the same cycle for the third sample S3 in which the nitriding treatment and the shot peening treatment were combined on the portion, and the fourth sample S4 on which no treatment was performed on the tip portion. I did it. The hardness of the tip portion of the first sample S1 and the third sample S3 is Hv1100 or more, the hardness of the tip portion of the second sample S2 is Hv1000 or more, and the hardness of the tip portion of the fourth sample S4 is less than 900. .

その結果、先端部分になんら処理が行なわれていない第４サンプルＳ４が試験開始後３ヶ月程度で溶断不能になった。しかし、先端部分に窒化処理が行なわれた第１サンプルＳ１、先端部分にショットピーニング処理が行なわれた第２サンプルＳ２、及び先端部分に窒化処理およびショットピーニング処理の複合処理が行なわれた第３サンプルＳ３は、６ヶ月を経過しても溶断不能にならなかった。これは、従来のサーメット合金製の溶断刃と同等レベルの耐久性である。特に、第３サンプルＳ３については、溶断回数にして１２００万回の耐久性を示した。   As a result, the fourth sample S4, which had not been subjected to any treatment on the tip portion, became unbreakable about 3 months after the start of the test. However, the first sample S1 in which the tip portion is subjected to nitriding, the second sample S2 in which the tip portion is subjected to shot peening, and the third portion in which the tip portion is subjected to a combination of nitriding and shot peening. Sample S3 did not become infusible after 6 months. This is the same level of durability as a conventional cutting blade made of a cermet alloy. In particular, the third sample S3 exhibited a durability of 12 million times as the number of times of fusing.

横シール時には、溶断刃５３の刃先は、筒状フィルムＦｍを挟んで受け刃５５と対峙する。また、溶断刃５３および受け刃５５は、ヒータ５１ｈによってシールジョー５１とほぼ同じ温度まで加熱される。   At the time of horizontal sealing, the cutting edge of the fusing blade 53 faces the receiving blade 55 with the tubular film Fm interposed therebetween. The fusing blade 53 and the receiving blade 55 are heated to substantially the same temperature as the sealing jaw 51 by the heater 51h.

（２−３―４−３）受け刃５５
第２シールジョー５１ｂの第２穴５１９内には受け刃５５が設けられている。受け刃５５の先端面は、第２シール面５１８から距離ｄだけ窪んでいる。 (2-3-4-3) receiving blade 55
A receiving blade 55 is provided in the second hole 519 of the second seal jaw 51b. The front end surface of the receiving blade 55 is recessed from the second seal surface 518 by a distance d.

（３）動作
次に、図３及び図５を参照しながら、第１シールジョー５１ａと第２シールジョー５１ｂの動作について説明する。なお、図３において一点鎖線で示されたシールジョーは旋回動作の一軌跡を示している。 (3) Operation Next, operations of the first seal jaw 51a and the second seal jaw 51b will be described with reference to FIGS. In addition, the seal jaw shown with the dashed-dotted line in FIG. 3 has shown one locus | trajectory of turning operation | movement.

第１シールジョー５１ａと第２シールジョー５１ｂとが筒状フィルムＦｍを挟んで円弧軌跡を描くように旋回する。先ず、第１シールジョー５１ａと第２シールジョー５１ｂとが旋回し筒状フィルムＦｍの挟み付けを開始したとき、最初に、第１下シール面５１６ｂ及び第２下シール面５１８ｂの下側部分で筒状フィルムＦｍを挟む。第１下シール面５１６ｂ及び第２下シール面５１８ｂは円弧面を筒状フィルムＦｍに押し付けるように一定角度回転して、筒状フィルムＦｍをシールする。   The first seal jaw 51a and the second seal jaw 51b rotate so as to draw an arc locus with the tubular film Fm interposed therebetween. First, when the first seal jaw 51a and the second seal jaw 51b turn to start the sandwiching of the tubular film Fm, first, at the lower portions of the first lower seal surface 516b and the second lower seal surface 518b. The tubular film Fm is sandwiched. The first lower seal surface 516b and the second lower seal surface 518b rotate by a certain angle so as to press the arc surface against the tubular film Fm, thereby sealing the tubular film Fm.

第１下シール面５１６ｂ及び第２下シール面５１８ｂによるシールが終了すると同時に、溶断刃５３と受け刃５５とが筒状フィルムＦｍを挟み込む。溶断刃５３の先端面は第１シール面５１６から距離ｄだけ突出し、受け刃５５の先端面は第２シール面５１８から距離ｄだけ窪んでいるので、溶断刃５３の先端面が筒状フィルムＦｍを受け刃５５の窪みに押し込むような状態となる。   At the same time as the sealing by the first lower seal surface 516b and the second lower seal surface 518b is completed, the fusing blade 53 and the receiving blade 55 sandwich the tubular film Fm. The front end surface of the fusing blade 53 protrudes from the first seal surface 516 by a distance d, and the front end surface of the receiving blade 55 is recessed from the second seal surface 518 by a distance d, so that the front end surface of the fusing blade 53 is a tubular film Fm. The receiving blade 55 is pushed into the recess.

溶断刃５３および受け刃５５は、ヒータ５１ｈによってシールジョー５１とほぼ同じ温度まで加熱されているので、筒状フィルムＦｍのうち溶断刃５３の先端面によって受け刃５５の窪みに押し込まれた部分が溶断される。   Since the fusing blade 53 and the receiving blade 55 are heated to almost the same temperature as the sealing jaw 51 by the heater 51h, the portion of the tubular film Fm that has been pushed into the recess of the receiving blade 55 by the front end surface of the fusing blade 53. Fusing.

筒状フィルムＦｍの溶断が完了した後、第１シールジョー５１ａの第１上シール面５１６ａ及び第２シールジョー５１ｂの第２上シール面５１８ａの下側部分が筒状フィルムＦｍを挟む。第１上シール面５１６ａ及び第２上シール面５１８ａは円弧面を筒状フィルムＦｍに押し付けるように一定角度回転して、筒状フィルムＦｍをシールする。   After the fusing of the tubular film Fm is completed, the lower portion of the first upper seal surface 516a of the first seal jaw 51a and the second upper seal surface 518a of the second seal jaw 51b sandwich the tubular film Fm. The first upper seal surface 516a and the second upper seal surface 518a rotate by a certain angle so as to press the arc surface against the tubular film Fm, thereby sealing the tubular film Fm.

このように、溶断刃５３および受け刃５５による筒状フィルムＦｍの溶断が完了したのちに、第１上シール面５１６ａ及び第２上シール面５１８ａによるシールが完了する。   Thus, after the fusing of the tubular film Fm by the fusing blade 53 and the receiving blade 55 is completed, the sealing by the first upper seal surface 516a and the second upper seal surface 518a is completed.

（４）特徴
（４−１）
この包装機では、少なくとも溶断刃５３の先端部分は、高速度工具鋼が使用され、窒化処理またはショットピーニング処理によって、硬さがＨｖ１０００以上に調整されている。また、第１シールジョー５１ａの第１上シール面５１６ａ及び第２シールジョー５１ｂの第２上シール面５１８ａが溶断予定部分の上流側を挟んでシールを完了する前に、溶断刃５３と受け刃５５とによる溶断予定部分の溶断が終了する。また、この包装機では、溶断刃の先端部分に、汎用材料である高速度工具鋼を適用し所定の硬さに調整されることによって、従来と同等の耐久性を確保することができる。その結果、溶断刃の材料費が低減され、さらに溶断刃の加工時間も短縮される。 (4) Features (4-1)
In this packaging machine, high-speed tool steel is used at least at the tip of the cutting blade 53, and the hardness is adjusted to Hv1000 or more by nitriding or shot peening. Further, before the first upper sealing surface 516a of the first sealing jaw 51a and the second upper sealing surface 518a of the second sealing jaw 51b complete the sealing across the upstream side of the portion to be fused, the fusing blade 53 and the receiving blade The fusing of the scheduled fusing part 55 is completed. In this packaging machine, high-speed tool steel, which is a general-purpose material, is applied to the tip portion of the cutting blade and adjusted to a predetermined hardness, thereby ensuring durability equivalent to the conventional one. As a result, the material cost of the cutting blade is reduced, and the processing time of the cutting blade is also shortened.

（４−２）
また、この包装機では、溶断刃５３の先端が刃渡り方向に沿って波形に成形されているので、筒状フィルムＦｍの溶断動作時に、溶断刃５３と受け刃５５との間に圧が一気にかからないので、溶断刃５３の耐久性が向上する。 (4-2)
Moreover, in this packaging machine, since the front-end | tip of the cutting blade 53 is shape | molded in the waveform along a blade span direction, a pressure does not apply at a stretch between the cutting blade 53 and the receiving blade 55 at the time of the cutting operation of the cylindrical film Fm. Therefore, the durability of the cutting blade 53 is improved.

（４―３）
さらに、この包装機では、溶断刃５３の先端の稜線を含む仮想面が、溶断刃５３の厚み方向に沿って湾曲する所定半径の円弧曲面である。 (4-3)
Furthermore, in this packaging machine, the virtual surface including the ridge line at the tip of the cutting blade 53 is an arc curved surface with a predetermined radius that curves along the thickness direction of the cutting blade 53.

（５）変形例
図６は、変形例に係る包装機の横シール機構１７の溶断刃５３の斜視図である。図６において、溶断刃５３は、中央部を成す有効刃５３１、両端部を成す無効刃５３２，５３３を有している。有効刃５３１は、実際に筒状フィルムＦｍを溶断する部分である。無効刃５３２，５３３は、筒状フィルムＦｍを溶断する機能はなく、有効刃５３１が、万が一、シール面に衝突したときに有効刃５３１の刃先５３１ａを保護する機能を有している。 (5) Modified Example FIG. 6 is a perspective view of the fusing blade 53 of the lateral seal mechanism 17 of the packaging machine according to the modified example. In FIG. 6, the fusing blade 53 has an effective blade 531 forming a central portion and invalid blades 532 and 533 forming both ends. The effective blade 531 is a part that actually melts the tubular film Fm. The invalid blades 532 and 533 have no function of fusing the tubular film Fm, and have a function of protecting the cutting edge 531a of the effective blade 531 when the effective blade 531 should collide with the seal surface.

具体的には、無効刃５３２の刃先５３２ａおよび無効刃５３３の刃先５３３ａでは、先端が有効刃５３１の刃先５３１ａよりもＣだけ突出している。この実施形態ではＣ＝０．５ｍｍであり、さらに、その突出部分は半径０．５ｍｍで丸められ、強度、耐摩耗性が高められている。   Specifically, at the cutting edge 532 a of the invalid blade 532 and the cutting edge 533 a of the invalid blade 533, the tips protrude from the cutting edge 531 a of the effective blade 531 by C. In this embodiment, C = 0.5 mm, and the protruding portion is rounded with a radius of 0.5 mm to enhance strength and wear resistance.

それゆえ、有効刃５３１が対向する第２シールジョー５１ｂのシール面（例えば、図１１Ａ参照）に衝突するような事態になっても、無効刃５３２の刃先５３２ａ及び無効刃５３３の刃先５３３ａが先にシール面に当たり、有効刃５３１の刃先５３１ａがシール面に衝突する事態を回避している。したがって、有効刃５３１の刃先５３１ａの欠けや、割れなどが防止される。   Therefore, even when the effective blade 531 collides with the sealing surface (for example, see FIG. 11A) of the second seal jaw 51b facing each other, the cutting edge 532a of the invalid blade 532 and the cutting edge 533a of the invalid blade 533 are advanced. The situation where the cutting edge 531a of the effective blade 531 hits the sealing surface and collides with the sealing surface is avoided. Therefore, chipping or cracking of the cutting edge 531a of the effective blade 531 is prevented.

＜第２実施形態＞
第１実施形態では、一対のシールジョーが旋回しながら筒状フィルムＦｍに対して円弧面で接触するが、それに限定されるものではない。ここでは、第１シールジョーと第２シールジョーとが旋回運動によって近接および離間を繰り返す、他の構成を説明する。 Second Embodiment
In the first embodiment, the pair of sealing jaws make contact with the circular film Fm while turning, but the present invention is not limited to this. Here, another configuration in which the first seal jaw and the second seal jaw repeat proximity and separation by a turning motion will be described.

（１）横シール機構１１７
図７は、第２実施形態に係る包装機の横シール機構１１７において旋回動作する第１シールジョー１５１ａと第２シールジョー１５１ｂの側面図である。なお、横シール機構１１７以外は第１実施形態と同じであるので、説明は省略する。また、図７において点線で示されたシールジョーは旋回動作の軌跡を示している。 (1) Horizontal seal mechanism 117
FIG. 7 is a side view of the first seal jaw 151a and the second seal jaw 151b that rotate in the lateral seal mechanism 117 of the packaging machine according to the second embodiment. In addition, since it is the same as 1st Embodiment except the horizontal seal mechanism 117, description is abbreviate | omitted. In addition, the seal jaw indicated by the dotted line in FIG. 7 indicates the trajectory of the turning motion.

第２実施形態は、第１シールジョー１５１ａと第２シールジョー１５１ｂが平面で筒状フィルムＦｍを挟んでＤ字状の軌跡を描くように旋回する点、及び、溶断刃１５３が第１ヒータ１５３ｈを有し、受け刃１５５が第２ヒータ１５５ｈを有している点で、第１実施形態と異なる。   In the second embodiment, the first sealing jaw 151a and the second sealing jaw 151b turn so as to draw a D-shaped trajectory with the cylindrical film Fm sandwiched between the flat surfaces, and the fusing blade 153 includes the first heater 153h. And the receiving blade 155 has a second heater 155h, which is different from the first embodiment.

しかも、制御部は、第１ヒータ１５３ｈ及び第２ヒータ１５５ｈそれぞれを個別に制御して、溶断刃１５３及び受け刃１５５をそれぞれ異なる溶断温度に調節する。   In addition, the control unit individually controls the first heater 153h and the second heater 155h to adjust the fusing blade 153 and the receiving blade 155 to different fusing temperatures.

また、制御部は、ヒータ５１ｈそれぞれを個別に制御して、第１シールジョー１５１ａと第２シールジョー１５１ｂの各部位それぞれを異なるシール温度に調節する。   Further, the control unit individually controls each of the heaters 51h to adjust the respective portions of the first seal jaw 151a and the second seal jaw 151b to different seal temperatures.

図８は、第１シールジョー１５１ａと第２シールジョー１５１ｂの動作のタイムチャートである。図８において、制御部は、溶断刃１５３及び受け刃１５５の動作を調節する。例えば、第１シールジョー１５１ａと第２シールジョー１５１ｂとがＤ字状に旋回するとき、第１シールジョー１５１ａと第２シールジョー１５１ｂとが筒状フィルムＦｍの挟み付けを開始した後に、溶断刃１５３を押し出して受け刃１５５との間で筒状フィルムＦｍを押圧して筒状フィルムＦｍの溶断を開始し、第１シールジョー１５１ａと第２シールジョー１５１ｂとが離反して筒状フィルムＦｍの挟み付けを終了する前に、溶断刃１５３を後退させて筒状フィルムＦｍの溶断を終了する。   FIG. 8 is a time chart of the operation of the first sealing jaw 151a and the second sealing jaw 151b. In FIG. 8, the control unit adjusts the operations of the fusing blade 153 and the receiving blade 155. For example, when the first seal jaw 151a and the second seal jaw 151b are swung in a D shape, the fusing blade is used after the first seal jaw 151a and the second seal jaw 151b start to sandwich the tubular film Fm. 153 is pushed out to press the tubular film Fm between the receiving blade 155 and the fusing of the tubular film Fm is started, and the first seal jaw 151a and the second seal jaw 151b are separated from each other to form the tubular film Fm. Before finishing the sandwiching, the fusing blade 153 is moved backward to finish fusing the tubular film Fm.

つまり、溶断開始時刻をシール開始時刻より遅くしながらも、溶断完了時刻ｔｃをシール完了時刻ｔｓより早くするのである。この場合、第１シールジョー１５１ａと第２シールジョー１５１ｂが時刻ｔｓに離反したときに袋は筒状フィルムＦｍと切り離されて落下する。   That is, the fusing completion time tc is made earlier than the sealing completion time ts while the fusing start time is later than the sealing start time. In this case, when the first sealing jaw 151a and the second sealing jaw 151b are separated from each other at time ts, the bag is separated from the tubular film Fm and dropped.

また、図９は、第１シールジョー１５１ａと第２シールジョー１５１ｂの動作の他のタイムチャートである。図９において、例えば、第１シールジョー１５１ａと第２シールジョー１５１ｂとがＤ字状に旋回するとき、第１シールジョー１５１ａと第２シールジョー１５１ｂとが対接して筒状フィルムＦｍの挟み付けを開始する前に、溶断刃１５３を押し出して受け刃１５５との間で筒状フィルムＦｍを押圧して筒状フィルムＦｍの溶断を開始し、第１シールジョー１５１ａと第２シールジョー１５１ｂとが離反して筒状フィルムＦｍの挟み付けを終了した後に、溶断刃１５３を後退させるようにしてもよい。   FIG. 9 is another time chart of the operation of the first seal jaw 151a and the second seal jaw 151b. In FIG. 9, for example, when the first seal jaw 151a and the second seal jaw 151b turn in a D shape, the first seal jaw 151a and the second seal jaw 151b come into contact with each other and sandwich the tubular film Fm. Before starting the cutting, the fusing blade 153 is pushed out to press the tubular film Fm between the receiving blade 155 and the fusing of the tubular film Fm is started, and the first sealing jaw 151a and the second sealing jaw 151b are The fusing blade 153 may be retracted after the separation and the sandwiching of the tubular film Fm is completed.

ただし、第１シールジョー１５１ａと第２シールジョー１５１ｂが離反する前の時刻ｔｃに、溶断は完了している。つまり、溶断開始時刻をシール開始時刻より早くし、かつ溶断完了時刻ｔｃもシール完了時刻ｔｓより早くするのである。この場合も、第１シールジョー１５１ａと第２シールジョー１５１ｂが時刻ｔｓに離反したときに袋は落下する。   However, the fusing is completed at time tc before the first seal jaw 151a and the second seal jaw 151b are separated. In other words, the fusing start time is set earlier than the seal start time, and the fusing completion time tc is also set earlier than the sealing completion time ts. Also in this case, the bag falls when the first seal jaw 151a and the second seal jaw 151b are separated at time ts.

以上のように、第２実施形態に係る包装機の横シール機構１１７は、筒状フィルムＦｍを溶着してシールする第１シールジョー１５１ａ及び第２シールジョー１５１ｂと、そのシール領域内の所定の部位を溶融して切断する溶断刃１５３及び受け刃１５５とを含んでいる。また、第１シールジョー１５１ａ及び第２シールジョー１５１ｂがヒータ５１ｈを有し、溶断刃１５３が第１ヒータ１５３ｈを有し、受け刃１５５が第２ヒータ１５５ｈを有している。それゆえ、それぞれ異なるシール温度と溶断温度との両方に適正に対応することが可能となり、ヒータ５１ｈで相対的に低いシール温度を設定しながら、第１ヒータ１５３ｈ及び第２ヒータ１５５ｈで相対的に高い溶断温度を設定することができる。その結果、筒状フィルムＦｍがシール領域で溶融して変形することを避けながら、同じ筒状フィルムＦｍを速やかに溶断することが可能となる。   As described above, the lateral sealing mechanism 117 of the packaging machine according to the second embodiment includes the first sealing jaw 151a and the second sealing jaw 151b that weld and seal the tubular film Fm, and the predetermined sealing area. A fusing blade 153 and a receiving blade 155 for melting and cutting the part are included. The first seal jaw 151a and the second seal jaw 151b have a heater 51h, the fusing blade 153 has a first heater 153h, and the receiving blade 155 has a second heater 155h. Therefore, it is possible to appropriately cope with both different sealing temperatures and fusing temperatures, and relatively set the first heater 153h and the second heater 155h while setting a relatively low sealing temperature with the heater 51h. A high fusing temperature can be set. As a result, it is possible to quickly melt the same tubular film Fm while avoiding melting and deformation of the tubular film Fm in the seal region.

なお、溶断刃１５３を受ける受け刃１５５の面は、第２シールジョー１５１ｂのシール面より奥に位置している。この構成によって、筒状フィルムＦｍが押されながら溶断されるようになり、その結果、溶着し易くなりフレアが防止される。   Note that the surface of the receiving blade 155 that receives the fusing blade 153 is located behind the sealing surface of the second seal jaw 151b. With this configuration, the tubular film Fm is melted while being pressed, and as a result, it becomes easy to weld and flare is prevented.

＜第３実施形態＞
上記第２実施形態では、第１シールジョーと第２シールジョーが平面で筒状フィルムＦｍを挟んでＤ字状の軌跡を描くように旋回する構成について説明した。しかし、これに限定されるものではない。例えば、第１シールジョーと第２シールジョーとが往復運動によって近接および離間を繰り返す構成であってもよい。この構成を第３実施形態として、以下に説明する。 <Third Embodiment>
In the second embodiment, the configuration in which the first sealing jaw and the second sealing jaw turn so as to draw a D-shaped trajectory with the tubular film Fm sandwiched between the flat surfaces is described. However, it is not limited to this. For example, the 1st seal jaw and the 2nd seal jaw may be the composition which repeats approach and separation by reciprocating motion. This configuration will be described below as a third embodiment.

FIG. 10 is a cross-sectional view of the cutting blade of the packaging machine according to the third embodiment. In addition, the cross-sectional position is the same position as the AOA line of FIG. In FIG. 10, the most advanced thickness t of the blade edge 253a is set to 0.05 mm or more and less than 0.2 mm. Furthermore, the cutting edge radius of curvature of the blade edge 253a is set to a radius of 0.05 mm or more and less than 0.2 mm following the conventional dimensions.

第１シールジョー２５１ａの第１ガイド穴５１３内には、溶断刃２５３が設けられている。また、第２シールジョー２５１ｂの第２ガイド穴５１５内には受け刃２５５が設けられている。溶断刃２５３の刃先は、筒状フィルムＦｍを挟んで受け刃２５５と対峙している。また、溶断刃２５３および受け刃２５５は、ヒータ２５１ｈによってシールジョー２５１とほぼ同じ温度まで加熱される。   A fusing blade 253 is provided in the first guide hole 513 of the first seal jaw 251a. A receiving blade 255 is provided in the second guide hole 515 of the second seal jaw 251b. The cutting edge of the fusing blade 253 is opposed to the receiving blade 255 with the tubular film Fm interposed therebetween. Further, the fusing blade 253 and the receiving blade 255 are heated to substantially the same temperature as the sealing jaw 251 by the heater 251h.

（２）横シール機構２１７の動作
図１１Ｂは、シールジョー２５１が動作を開始したときの横シール機構２１７の断面図である。図１１Ｂにおいて、制御部は、駆動機構（図示せず）を介して、第１シールジョー２５１ａと第２シールジョー２５１ｂとを接近させ、溶断刃２５３の先端と受け刃２５５の先端とで筒状フィルムＦｍを挟み込む。それゆえ、筒状フィルムＦｍは溶断刃２および受け刃２５５によって両側から所定に圧力で押される。 (2) Operation of Lateral Seal Mechanism 217 FIG. 11B is a cross-sectional view of the lateral seal mechanism 217 when the seal jaw 251 starts operation. In FIG. 11B, the control unit causes the first seal jaw 251a and the second seal jaw 251b to approach each other via a drive mechanism (not shown), and the tip of the fusing blade 253 and the tip of the receiving blade 255 are cylindrical. Insert the film Fm. Therefore, the tubular film Fm is pressed with a predetermined pressure from both sides by the fusing blade 2 and the receiving blade 255.

このとき、溶断刃２５３および受け刃２５５は、ヒータ２５１ｈによって加熱されているので、溶断刃２５３および受け刃２５５は、筒状フィルムＦｍとの接触部分に熱と圧力とを与え、筒状フィルムＦｍを溶着しつつ切断する。   At this time, since the fusing blade 253 and the receiving blade 255 are heated by the heater 251h, the fusing blade 253 and the receiving blade 255 give heat and pressure to the contact portion with the tubular film Fm, and the tubular film Fm. Cut while welding.

図１１Ｃは、第１シールジョー２５１ａと第２シールジョー２５１ｂとが密着したときの横シール機構２１７の断面図である。図１１Ｃにおいて、第１シールジョー２５１ａのシール面と第２シールジョー２５１ｂのシール面とは、筒状フィルムＦｍを挟んで密着する。受け刃２５５の後端部分には付勢部材２５７が連結されており、受け刃２５５は溶断刃２５３に押されて第２ガイド穴５１５の奥へ後退する。このとき、ヒータ２５１ｈよって加熱されているシール面が、所定時間をかけて筒状フィルムＦｍを熱シールする。   FIG. 11C is a cross-sectional view of the lateral seal mechanism 217 when the first seal jaw 251a and the second seal jaw 251b are in close contact with each other. In FIG. 11C, the sealing surface of the first sealing jaw 251a and the sealing surface of the second sealing jaw 251b are in close contact with each other with the tubular film Fm interposed therebetween. A biasing member 257 is connected to the rear end portion of the receiving blade 255, and the receiving blade 255 is pushed by the fusing blade 253 and retracts to the back of the second guide hole 515. At this time, the sealing surface heated by the heater 251h heat seals the tubular film Fm over a predetermined time.

図１１Ｄは、第１シールジョー２５１ａと第２シールジョー２５１ｂと離間させたときの横シール機構２１７の断面図である。図１１Ｄにおいて、熱シール終了後、筒状フィルムＦｍから生成された包装袋の端部は、シール部分と溶断部分とで二重に閉じられた状態となっている。   FIG. 11D is a cross-sectional view of the lateral seal mechanism 217 when the first seal jaw 251a and the second seal jaw 251b are separated from each other. In FIG. 11D, after the end of heat sealing, the end portion of the packaging bag generated from the tubular film Fm is in a state of being double-closed by the sealing portion and the fusing portion.

（３）特徴
（３−１）
横シール機構２１７では、溶断刃２５３の先端部分に高速度工具鋼が使用され、窒化処理またはショットピーニング処理によって、硬さがＨｖ１０００以上に調整されている。その結果、従来のサーメット合金製の溶断刃と同等の性能を確保することができ、溶断刃２５３の材料費が低減され、さらに溶断刃２５３の加工時間も短縮される。 (3) Features (3-1)
In the horizontal sealing mechanism 217, high-speed tool steel is used for the tip portion of the cutting blade 253, and the hardness is adjusted to Hv1000 or more by nitriding or shot peening. As a result, the same performance as that of the conventional cutting blade made of cermet alloy can be secured, the material cost of the cutting blade 253 is reduced, and the processing time of the cutting blade 253 is also shortened.

（３−２）
溶断刃２５３の刃先２５３ａの幅は０．０５ｍｍ以上、０．２ｍｍ未満であるので、刃先２５３ａの耐摩耗性が向上する。 (3-2)
Since the width of the cutting edge 253a of the fusing blade 253 is 0.05 mm or more and less than 0.2 mm, the wear resistance of the cutting edge 253a is improved.

以上のように本発明によれば、溶断刃の耐久性が高まるので、包装機の横シール機構（溶断装置）だけに限らず、加熱金属で樹脂部材を溶断する装置にも有用である。   As described above, according to the present invention, since the durability of the fusing blade is increased, it is useful not only for the lateral sealing mechanism (fusing device) of a packaging machine but also for an apparatus for fusing a resin member with a heated metal.
