Description
本発明は、被シール物を熱溶着によりシールするヒートシーラーに関し、特にハンディ型のヒートシーラーに関する。 The present invention relates to a heat sealer that seals an object to be sealed by heat welding, and more particularly to a handy heat sealer.
従来から、樹脂やアルミニウム等からなる袋状の被シール物に対して、その開口縁の樹脂部分を２つの圧接部によって挟み込み、該圧接部から被シール物の当該樹脂部分に熱を加えることにより、被シール物の開口を熱溶着によってシールするヒートシーラーが知られている。ヒートシーラーとしては、大型で被シール物の熱溶着を自動で行うものや、小型で人が手動で操作可能なもの等の種々の型が知られている。 Conventionally, by sandwiching a resin part at the opening edge of a bag-like object to be sealed made of resin, aluminum or the like by two pressure contact parts, and applying heat to the resin part of the object to be sealed from the pressure contact part A heat sealer that seals the opening of an object to be sealed by heat welding is known. Various types of heat sealers are known, such as a large one that automatically heat-seals an object to be sealed and a small one that can be manually operated by a person.
特許文献１及び２には、使用者自身が持つことができて手動で操作可能なハンディ型のヒートシーラーが開示されている。特許文献１及び２に開示のヒートシーラーは、被シール物を挟み込むための第１圧接部及び第２圧接部と、使用者がヒートシーラーを持つための把持部と、第１圧接部を第２圧接部に当接するように動かすための操作レバーとを備えている。使用者は、ヒートシーラーの把持部と共に操作レバーを握ることにより第１圧接部を第２圧接部に当接させることができ、その結果、被シール物を２つの圧接部によって挟み込むことができる。また、特許文献１及び２に開示のヒートシーラーには、操作レバーが把持部から離れる（第１圧接部が第２圧接部から離れる方向）方向に付勢させるばね部材が設けられており、これにより、使用者が操作レバーを握ったときのみ、第１圧接部が第２圧接部に当接するように構成されている。このようなハンディ型のヒートシーラーは、比較的軽量であり、操作が簡便であるため、使用者が扱いやすい。 Patent Documents 1 and 2 disclose a hand-held heat sealer that can be held by a user and can be manually operated. The heat sealers disclosed in Patent Documents 1 and 2 include a first pressure contact portion and a second pressure contact portion for sandwiching an object to be sealed, a grip portion for a user to have a heat sealer, and a first pressure contact portion. And an operation lever for moving so as to abut against the press contact portion. The user can bring the first pressure contact portion into contact with the second pressure contact portion by grasping the operation lever together with the grip portion of the heat sealer, and as a result, the object to be sealed can be sandwiched between the two pressure contact portions. In addition, the heat sealers disclosed in Patent Documents 1 and 2 are provided with a spring member that urges the operation lever in a direction in which the operation lever is separated from the gripping portion (the direction in which the first pressure contact portion is separated from the second pressure contact portion). Thus, the first pressure contact portion is configured to come into contact with the second pressure contact portion only when the user holds the operation lever. Such a hand-held heat sealer is relatively lightweight and easy to operate, and is easy for the user to handle.
しかしながら、特許文献１及び２に開示のヒートシーラーは、上述の通り、操作レバーを把持部から離れる方向に付勢させるためにばね部材が設けられているため、繰り返しの使用によってばね部材が磨耗することとなる。そうすると、ばね部材から金属の磨耗屑が生じ、例えば被シール物が所定の製品等を入れた袋体である場合、袋体内に金属屑が混入してコンタミネーションが生じるおそれがある。例えば、袋体内に電池の活物質材料等が入っている場合、ヒートシーラーの使用によってばね部材から金属屑が生じて袋体内に混入すると、該材料を用いた電池製品の性能や安全性に影響を与えることとなる。 However, since the heat sealers disclosed in Patent Documents 1 and 2 are provided with a spring member to bias the operation lever in a direction away from the gripping portion as described above, the spring member is worn by repeated use. It will be. In this case, metal wear debris is generated from the spring member. For example, when the object to be sealed is a bag containing a predetermined product or the like, there is a possibility that metal debris enters the bag and contamination occurs. For example, if battery active material or the like is contained in the bag body, metal waste generated from the spring member due to the use of a heat sealer and mixed in the bag body will affect the performance and safety of battery products using the material. Will be given.
本発明は、前記の問題に鑑みてなされたものであり、その目的は、繰り返し使用してもコンタミネーションの原因となる金属屑の発生を防止できるヒートシーラーを得ることにある。 This invention is made | formed in view of the said problem, The objective is to obtain the heat sealer which can prevent generation | occurrence | production of the metal waste which causes a contamination even if it uses repeatedly.
前記の目的を達成するために、本発明では、ヒートシーラーの第１圧接部と第２圧接部とを反対方向に付勢させるために磁石部材を用いた。 In order to achieve the above object, in the present invention, a magnet member is used to bias the first pressure contact portion and the second pressure contact portion of the heat sealer in opposite directions.
具体的に、本発明に係るヒートシーラーは、被シール物を挟み込むための第１圧接部及び第２圧接部と、該第１圧接部及び第２圧接部を加熱するためのヒータとを備えた、被シール物を熱溶着させるヒートシーラーであって、第１圧接部に接続された第１把持部と、第２圧接部に接続された第２把持部とをさらに備え、第１把持部及び第２把持部が共に把持されると第１圧接部と第２圧接部とが当接するように構成され、第１把持部及び第２把持部が共に把持されたときに、互いに接触せずに且つ反発力が生じる位置に第１磁石部材及び該第１磁石部材と同一の極性を有する第２磁石部材が配置されていることを特徴とする。 Specifically, a heat sealer according to the present invention includes a first pressure contact portion and a second pressure contact portion for sandwiching an object to be sealed, and a heater for heating the first pressure contact portion and the second pressure contact portion. A heat sealer for thermally welding an object to be sealed, further comprising: a first gripping part connected to the first pressure contact part; and a second gripping part connected to the second pressure contact part; The first pressure contact portion and the second pressure contact portion are configured to come into contact with each other when the second gripping portion is gripped together, and when the first gripping portion and the second gripping portion are gripped together, they do not contact each other. And the 1st magnet member and the 2nd magnet member which has the same polarity as this 1st magnet member are arrange | positioned in the position where a repulsive force produces.
本発明に係るヒートシーラーによると、第１把持部及び第２把持部が共に把持された状態のときに、互いに接触せずに且つ反発力が生じる位置に第１磁石部材及び第２磁石部材が配置されている。従って、被シール物をシールするために、使用者により第１把持部及び第２把持部が共に把持されて、第１圧接部及び第２圧接部によって被シール物を挟み込んだときに、第１磁石部材と第２磁石部材とが接近して互いに反発し合うため、第１把持部及び第２把持部は互いに離れる方向に付勢される。このため、使用者が第１把持部及び第２把持部を共に把持したときのみに、第１圧接部と第２圧接部とを互いに当接させて、被シール物を熱溶着させることができる。本発明のヒートシーラーでは、従来のようなばね部材ではなく、互いに反発する第１磁石部材及び第２磁石部材を用いており、これらは接触しないように配置されているため、繰り返し使用しても、第１磁石部材及び第２磁石部材が磨耗することはない。このため、金属屑が発生することがなく、被シール物内において望まれない混入物が入り込み、コンタミネーションが起こることを防止できる。 According to the heat sealer of the present invention, when the first gripping part and the second gripping part are both gripped, the first magnet member and the second magnet member are not in contact with each other and the repulsive force is generated. Has been placed. Accordingly, in order to seal the object to be sealed, the first gripping part and the second gripping part are both gripped by the user, and when the object to be sealed is sandwiched between the first pressure contact part and the second pressure contact part, Since the magnet member and the second magnet member are close to each other and repel each other, the first gripping portion and the second gripping portion are urged away from each other. For this reason, only when the user grips both the first gripping portion and the second gripping portion, the first press-contact portion and the second press-contact portion can be brought into contact with each other to heat-seal the object to be sealed. . In the heat sealer of the present invention, the first magnet member and the second magnet member that repel each other are used instead of the conventional spring member, and these are arranged so as not to come into contact with each other. The first magnet member and the second magnet member are not worn. For this reason, metal waste is not generated, and it is possible to prevent contamination from entering due to unwanted contaminants entering the object to be sealed.
本発明に係るヒートシーラーにおいて、第１圧接部と第１把持部との間に配設され、第１圧接部と第１把持部とを接続する第１接続部材と、第２圧接部と第２把持部との間に配設され、第２圧接部と第２把持部とを接続する第２接続部材とをさらに備え、第１接続部材と第２接続部材とは交差し、交差する部分は、第１把持部及び第２把持部が共に把持されると交差する部分を支点として、第１圧接部と第２圧接部とが互いに当接する方向に連動するように、組み付けられていることが好ましい。 In the heat sealer according to the present invention, a first connecting member that is disposed between the first pressure contact portion and the first gripping portion and connects the first pressure contact portion and the first gripping portion, a second pressure contact portion, and a first pressure contact portion. A second connecting member that is disposed between the two gripping portions and connects the second press-contact portion and the second gripping portion, and the first connecting member and the second connecting member intersect with each other. Is assembled so that the first press contact portion and the second press contact portion are interlocked with each other with a portion that intersects when the first grip portion and the second grip portion are gripped as a fulcrum. Is preferred.
このようにすると、本発明に係るヒートシーラーはハサミと同様の構造となり、すなわち第１接続部材と第２接続部材とが交差する部分が支点となり、第１把持部及び第２把持部が力点となり、第１圧接部及び第２圧接部が作用点として機能する。従って、使用者は把持のみの動作によってヒートシーラーを簡便に操作することができる。 In this case, the heat sealer according to the present invention has the same structure as the scissors, that is, the portion where the first connecting member and the second connecting member intersect serves as a fulcrum, and the first gripping portion and the second gripping portion serve as a power point. The first pressure contact portion and the second pressure contact portion function as an action point. Therefore, the user can easily operate the heat sealer only by gripping operation.
この場合、第１接続部材は、第１把持部と一体に形成され、第２接続部材は、第２把持部と一体に形成されていてもよい。 In this case, the first connection member may be formed integrally with the first grip portion, and the second connection member may be formed integrally with the second grip portion.
このようにすると、部品点数を削減することが可能となる。 In this way, the number of parts can be reduced.
本発明に係るヒートシーラーにおいて、第１磁石部材は、第１接続部材に固定され、第２磁石部材は、第２接続部材に固定され、第１把持部及び第２把持部が共に把持されたときに、第１磁石部材及び第２磁石部材は、互いに対向するように配置されていることが好ましい。 In the heat sealer according to the present invention, the first magnet member is fixed to the first connecting member, the second magnet member is fixed to the second connecting member, and both the first gripping portion and the second gripping portion are gripped. Sometimes, the first magnet member and the second magnet member are preferably arranged so as to face each other.
このようにすると、第１把持部及び第２把持部が共に把持されたときに、第１磁石部材及び第２磁石部材が互いに反発し合うため、第１接続部材及び第２接続部材が互いに上記支点を中心に反対方向に回動するように付勢される。その結果、第１圧接部及び第２圧接部が互いに離間する方向に付勢される。 If it does in this way, when the 1st holding part and the 2nd holding part are held together, since the 1st magnet member and the 2nd magnet member repel each other, the 1st connection member and the 2nd connection member mutually mentioned above It is biased to rotate in the opposite direction around the fulcrum. As a result, the first press contact portion and the second press contact portion are urged in a direction away from each other.
さらにこの場合、交差する部分における第１接続部材と第２接続部材との間には、第１接続部材及び第２接続部材と接続する軸部が設けられ、第１接続部材及び第２接続部材は、軸部に該軸部を軸として回動可能に接続されていてもよい。 Further, in this case, a shaft portion connected to the first connecting member and the second connecting member is provided between the first connecting member and the second connecting member at the intersecting portion, and the first connecting member and the second connecting member are provided. May be connected to the shaft portion so as to be rotatable about the shaft portion.
本発明に係るヒートシーラーにおいて、第１接続部材及び第２接続部材は、樹脂材料からなることが好ましい。 In the heat sealer according to the present invention, the first connection member and the second connection member are preferably made of a resin material.
上記構造の場合、第１接続部材及び第２接続部材に支点が存在するため、ヒートシーラーを繰り返し使用することにより、第１接続部材及び第２接続部材が磨耗したとしても、金属屑は発生しない。 In the case of the above structure, since the fulcrum exists in the first connecting member and the second connecting member, even if the first connecting member and the second connecting member are worn by repeated use of the heat sealer, no metal scrap is generated. .
本発明に係るヒートシーラーにおいて、第１把持部及び第２把持部は、樹脂材料からなることが好ましい。 In the heat sealer according to the present invention, the first grip portion and the second grip portion are preferably made of a resin material.
第１把持部及び第２把持部は使用者に直接把持される部分であるため、ヒートシーラーを繰り返し使用することで、磨耗するおそれがあるが、樹脂材料からなるため磨耗したとしても、金属屑は発生しない。 Since the first gripping portion and the second gripping portion are directly gripped by the user, there is a risk of wearing by repeatedly using the heat sealer. Does not occur.
本発明に係るヒートシーラーにおいて、第１圧接部及び第２圧接部は、ヒータによって効率良く加熱されるために、熱伝導率が高く、且つ、熱膨張率が低い金属製であることが好ましく、熱伝導率及び重量の観点からアルミニウム製であることがより好ましい。 In the heat sealer according to the present invention, the first pressure contact portion and the second pressure contact portion are preferably made of metal having a high thermal conductivity and a low thermal expansion coefficient in order to be efficiently heated by the heater. From the viewpoint of thermal conductivity and weight, aluminum is more preferable.
このようにアルミニウムを用いると、上記理由により第１圧接部及び第２圧接部に鉄等の金属材料を用いるよりもヒートシーラー全体の重量を軽量にすることができる。 When aluminum is used in this way, the weight of the heat sealer as a whole can be reduced compared to the case where a metal material such as iron is used for the first pressure contact portion and the second pressure contact portion for the reasons described above.
本発明に係るヒートシーラーにおいて、第１圧接部及び第２圧接部は、該第１圧接部及び第２圧接部を貫通するように設けられたスリットを有することが好ましい。 In the heat sealer according to the present invention, it is preferable that the first pressure contact portion and the second pressure contact portion have a slit provided so as to penetrate the first pressure contact portion and the second pressure contact portion.
このようにすると、第１圧接部及び第２圧接部によって被シール物を挟み込む際に、被シール物が第１圧接部及び第２圧接部の陰に隠れても、スリットにより被シール物を目視できるため、被シール物を挟み込む操作をより正確に行うことが可能となる。 In this way, when the object to be sealed is sandwiched between the first pressure contact part and the second pressure contact part, the object to be sealed is visually observed by the slit even if the object to be sealed is hidden behind the first pressure contact part and the second pressure contact part. Therefore, it is possible to perform the operation of sandwiching the object to be sealed more accurately.
本発明に係るヒートシーラーは、被シール物として電池材料を含む袋体の開口をシールすることを用途とすることが好ましい。 The heat sealer according to the present invention is preferably used for sealing an opening of a bag body containing a battery material as an object to be sealed.
本発明に係るヒートシーラーは、上述のように、繰り返しの使用による金属屑の発生を防止できるため、金属の異物が混入すると製品の性能及び安全性に影響が生じる電池材料を含む袋体の開口をシールするのに適している。 As described above, the heat sealer according to the present invention can prevent generation of metal scraps due to repeated use. Therefore, when metal foreign matter is mixed in, the opening of the bag body containing battery materials that affect the performance and safety of the product is affected. Suitable for sealing.
本発明に係るヒートシーラーによると、繰り返し使用してもコンタミネーションの原因となる金属屑の発生を防止できる。 According to the heat sealer according to the present invention, it is possible to prevent generation of metal scraps that cause contamination even when used repeatedly.
以下、本発明を実施するための形態を説明する。以下の好ましい実施形態の説明は、本質的に例示に過ぎず、本発明、その適用方法或いはその用途を制限することを意図するものではない。 Hereinafter, modes for carrying out the present invention will be described. The following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the invention, its method of application, or its application.
本発明の一実施形態に係るヒートシーラーについて、図面を参照しながら説明する。図１〜図４に示すように、本実施形態のヒートシーラー１０は、被シール物（図示せず）を挟み込んで熱溶着（シール）するための第１圧接部１１及び第２圧接部１２を有する。第１圧接部１１及び第２圧接部１２は、その外形が断面略矩形の棒形状であり、その内部は中空となっている。また、第１圧接部１１及び第２圧接部１２は、図１に示すような互いに近接した状態において、それぞれの互いに対向する面の一部が相手側に向かって突出した突出部１１ａ、１２ａを有する。従って、被シール物は突出部１１ａ、１２ａによって挟み込まれることとなる。また、突出部１１ａ、１２ａの互いに対向する面のそれぞれには、断面波状となるようにそれらの長手方向に並行に延びる複数の溝が設けられている。 A heat sealer according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, the heat sealer 10 of the present embodiment includes a first pressure contact portion 11 and a second pressure contact portion 12 for sandwiching an object to be sealed (not shown) and performing heat welding (seal). Have. The first press-contact portion 11 and the second press-contact portion 12 have a rod shape whose outer shape is substantially rectangular in cross section, and the inside is hollow. In addition, the first pressure contact portion 11 and the second pressure contact portion 12 are provided with protrusions 11a and 12a in which a part of surfaces facing each other protrude toward the other side in the state of being close to each other as shown in FIG. Have. Accordingly, the object to be sealed is sandwiched between the protruding portions 11a and 12a. In addition, a plurality of grooves extending in parallel in the longitudinal direction are provided on each of the opposing surfaces of the protrusions 11a and 12a so as to have a corrugated cross section.
本実施形態において、図１、図２に示すように突出部１１ａ、１２ａは、それぞれ第１圧接部１１及び第２圧接部１２と一体的に形成されているが、それらは別体として形成されていてもよい。このようにすると、突出部１１ａ、１２ａが第１圧接部１１及び第２圧接部１２に着脱可能に構成することができ、被シール物に直接接触する突出部１１ａ、１２ａを交換可能にすることができる。その場合、突出部１１ａ、１２ａは、それぞれ第１圧接部１１及び第２圧接部１２に対して、以下のものに限られないが、例えば締結具や接着剤等を用いて接続することができる。但し、ヒートシーラー１０の使用中における締結具の脱落のおそれも考えられ、例えば袋体である被シール物内のコンタミネーションの防止の観点から、締結具を用いないことが好ましい。 In the present embodiment, as shown in FIGS. 1 and 2, the projecting portions 11a and 12a are integrally formed with the first press contact portion 11 and the second press contact portion 12, respectively, but they are formed as separate bodies. It may be. If it does in this way, protrusion part 11a, 12a can be comprised so that attachment or detachment is possible to the 1st press-contact part 11 and the 2nd press-contact part 12, and protrusion part 11a, 12a which contacts a to-be-sealed thing directly is made exchangeable. Can do. In that case, although the protrusion parts 11a and 12a are not restricted to the following with respect to the 1st press-contact part 11 and the 2nd press-contact part 12, respectively, it can connect using a fastener, an adhesive agent, etc., for example. . However, there is a possibility that the fastener may fall off during use of the heat sealer 10, and it is preferable not to use a fastener from the viewpoint of preventing contamination in the sealed object that is a bag, for example.
上記第１圧接部１１及び第２圧接部１２の中空部分には、それぞれ第１圧接部１１及び第２圧接部１２を加熱するためのヒータ１３が設けられている。ヒータ１３は、第１圧接部１１及び第２圧接部１２を効率良く加熱するために、図３及び図４に示すように、第１圧接部１１及び第２圧接部１２の長手方向に沿って配置されている。本実施形態のヒートシーラー１０の使用時において、ヒータ１３により、第１圧接部１１及び第２圧接部１２が加熱され、これにより、突出部１１ａ、１２ａも昇温するので、被シール物を第１圧接部１１及び第２圧接部１２の突出部１１ａ、１２ａで挟み込むことにより、被シール物が熱溶着されることとなる。 Heaters 13 for heating the first press contact portion 11 and the second press contact portion 12 are provided in the hollow portions of the first press contact portion 11 and the second press contact portion 12, respectively. In order to efficiently heat the first press contact portion 11 and the second press contact portion 12, the heater 13 extends along the longitudinal direction of the first press contact portion 11 and the second press contact portion 12 as shown in FIGS. 3 and 4. Has been placed. When the heat sealer 10 of this embodiment is used, the first pressure contact portion 11 and the second pressure contact portion 12 are heated by the heater 13, whereby the temperature of the protruding portions 11 a and 12 a is also raised. The object to be sealed is thermally welded by being sandwiched between the protruding portions 11a and 12a of the first press contact portion 11 and the second press contact portion 12.
第１圧接部１１、第２圧接部１２及びそれらの突出部１１ａ、１２ａは、ヒータ１３に効率良く加熱されるために、熱伝導率が高く、且つ、熱膨張率が低い金属製であることが好ましく、熱伝導率及び重量の観点からアルミニウム製であることがより好ましいが、これに限らず、他にチタン等を用いることもできる。また、ヒータ１３としては第１圧接部１１及び第２圧接部１２を加熱できるものであれば特に限定されないが、例えばニクロム線を用いたニクロム系ヒータ等を用いることができる。本実施形態では、第１圧接部１１、第２圧接部１２及びそれらの突出部１１ａ、１２ａはアルミニウム製であり、１００Ｖの電源によりニクロム線は第１圧接部１１及び第２圧接部１２が約２００℃程度まで加熱されるように構成されている。但し、本発明のヒートシーラー１０はこの構成に限られず、所望の温度に第１圧接部１１及び第２圧接部１２を加熱できるように、ニクロム線の長さ及び太さを適宜調整してもよく、また、電源の電圧を変更してもよく、さらに、ニクロム線以外の加熱手段を用いても構わない。 The first pressure contact portion 11, the second pressure contact portion 12, and the protrusions 11a and 12a are made of metal having high thermal conductivity and low thermal expansion coefficient in order to be efficiently heated by the heater 13. However, it is more preferable to use aluminum from the viewpoint of thermal conductivity and weight, but not limited to this, titanium or the like can also be used.

As a result, the first press contact portion 11 and the second press contact portion 12 move in a direction away from each other, resulting in the state shown in FIG. On the other hand, when the user holds both the first holding part 14 and the second holding part 15 from the state shown in FIG. 2, the first holding part side connecting piece 17a and the second holding part side connecting piece 18a have the above orientation. Respectively rotate in the opposite directions, and as a result, the first press contact portion 11 and the second press contact portion 12 move in directions close to each other, and the state shown in FIG. 1 is obtained. That is, in the heat sealer 10 according to the present embodiment, the first gripping portion 14 and the second gripping portion 15 serve as power points, the shaft portion 19 serves as a fulcrum, and the first press contact portion 11 and the second press contact portion 12 serve as action points. Since the structure is similar to that of scissors, the user can easily operate the heat sealer only by gripping.
本実施形態では、第１接続部材１７及び第２接続部材１８は、それぞれ第１把持部１４及び第２把持部１５に締結されていたが、第１接続部材１７と第１把持部１４とが一体に形成されていてもよく、同様に第２接続部材１８と第２把持部１５とが一体に形成されていてもよい。すなわち、第１把持部１４が第１圧接部１１にまで連続的に延びて接続していてもよく、同様に、第２把持部１５が第２圧接部１２にまで連続的に延びて接続していてもよい。 In the present embodiment, the first connecting member 17 and the second connecting member 18 are fastened to the first gripping part 14 and the second gripping part 15, respectively. However, the first connecting member 17 and the first gripping part 14 are connected to each other. The second connecting member 18 and the second gripping part 15 may be formed integrally as well. That is, the first grip 14 may be continuously extended and connected to the first pressure contact portion 11. Similarly, the second grip 15 may be continuously extended and connected to the second pressure contact portion 12. It may be.
また、本実施形態に係るヒートシーラー１０において、第１把持部側接続片１７ａの第２把持部側接続片１８ａと反対側（下側）には、第１圧接部１１の長手方向と並行に延びる第１台座部２０が取り付けられている。第１台座部２０の長手方向両端部には、それぞれ第２把持部側接続片１８ａ側（上側）に向かうように配置された第１磁石部材２１が締結具により締結されている。 Further, in the heat sealer 10 according to the present embodiment, the first gripping portion side connection piece 17a is opposite to the second gripping portion side connection piece 18a (lower side) in parallel with the longitudinal direction of the first pressure contact portion 11. An extending first pedestal portion 20 is attached. A first magnet member 21 disposed so as to be directed toward the second gripping portion side connecting piece 18a side (upper side) is fastened to both ends in the longitudinal direction of the first pedestal portion 20 by a fastener.
同様に、第２把持部側接続片１８ａの第１把持部側接続片１７ａと反対側（上側）には、第２圧接部１２の長手方向と並行に延びる第２台座部２２が取り付けられている。第２台座部２２の長手方向両端部には、それぞれ第１把持部側接続片１７ａ側（下側）に向かうように配置され、特に第１磁石部材２１に対応する位置に配置された第２磁石部材２３が締結具により締結されている。従って、図１に示すように、第１圧接部１１の突出部１１ａと第２圧接部１２の突出部１２ａとが当接した状態のとき、第１磁石部材２１と第２磁石部材２３とは互いに対向し、極めて近い位置となるように配置される。但し、第１磁石部材２１と第２磁石部材２３とは互いに接触しないように配置されている。 Similarly, a second pedestal portion 22 extending in parallel with the longitudinal direction of the second pressure contact portion 12 is attached to the second gripping portion side connection piece 18a on the opposite side (upper side) of the first gripping portion side connection piece 17a. Yes. The second pedestal portion 22 is disposed at both ends in the longitudinal direction so as to be directed to the first gripping portion side connection piece 17a side (lower side), and in particular, at a position corresponding to the first magnet member 21. The magnet member 23 is fastened by a fastener. Therefore, as shown in FIG. 1, when the protruding portion 11 a of the first press contact portion 11 and the protruding portion 12 a of the second press contact portion 12 are in contact with each other, the first magnet member 21 and the second magnet member 23 are It arrange | positions so that it may mutually oppose and may become a very near position. However, the first magnet member 21 and the second magnet member 23 are arranged so as not to contact each other.
また、第１磁石部材２１及び第２磁石部材２３は、互いに反発し合う極性を有し、すなわち同一の極性を有している。従って、図１に示すように、第１圧接部１１と第２圧接部１２とが当接した状態のとき、第１磁石部材２１と第２磁石部材２３とは互いに反発し合う。このため、第１磁石部材２１が締結された第１把持部側接続片１７ａと、第２磁石部材２３が締結された第２把持部側接続片１８ａとは、軸部１９を軸として互いに反対方向（図１において第１把持部側接続片１７ａは左回り、第２把持部側接続片１８ａは右回り）に付勢される。 Moreover, the 1st magnet member 21 and the 2nd magnet member 23 have the polarity which mutually repels, ie, has the same polarity. Therefore, as shown in FIG. 1, when the first pressure contact portion 11 and the second pressure contact portion 12 are in contact with each other, the first magnet member 21 and the second magnet member 23 repel each other. For this reason, the 1st holding part side connection piece 17a to which the 1st magnet member 21 was fastened, and the 2nd holding part side connection piece 18a to which the 2nd magnet member 23 were fastened are mutually opposite about a shaft part 19 as an axis. It is urged in the direction (in FIG. 1, the first gripping part side connection piece 17a is counterclockwise and the second gripping part side connection piece 18a is clockwise).
第１磁石部材２１及び第２磁石部材２３としては、特に限定されないが、例えば、ネオジム磁石、コバルト磁石又はフェライト磁石等を用いることができるが、ネオジム磁石を用いることが好ましい。また、第１磁石部材２１及び第２磁石部材の磁力の強さや、それらの間の間隙の距離についても、使用者が把持した状態から力を抜いたときに、それらの反発力により第１把持部側接続片１７ａ及び第２把持部側接続片１８ａを反対方向に回動させて第１圧接部１１と第２圧接部１２とを離間させることができれば特に限定されない。例えば、第１磁石部材２１及び第２磁石部材２３として、磁力が約４０００ガウスのネオジム磁石であるＮＨＸＣＣ２０−４（株式会社ミスミ製）を用いる場合、使用者が第１把持部１４及び第２把持部１５を把持した状態で、第１磁石部材２１と第２磁石部材２３との間の間隙は１ｍｍ以下であることが好ましい。間隙をこのように設定すると、使用者が第１把持部１４及び第２把持部１５を把持した際に、第１磁石部材２１と第２磁石部材２３とが強く反発するため、第１圧接部１１と第２圧接部１２とを離間させるのに十分な力を得ることができる。 Although it does not specifically limit as the 1st magnet member 21 and the 2nd magnet member 23, For example, although a neodymium magnet, a cobalt magnet, a ferrite magnet, etc. can be used, it is preferable to use a neodymium magnet. Further, regarding the strength of the magnetic force of the first magnet member 21 and the second magnet member and the distance between the first magnet member 21 and the user, when the force is removed from the gripped state, the first gripping force is generated by the repulsive force. If the part side connection piece 17a and the 2nd holding part side connection piece 18a can be rotated in the opposite direction and the 1st press-contact part 11 and the 2nd press-contact part 12 can be spaced apart, it will not specifically limit. For example, when NHXCC20-4 (manufactured by MISUMI Corporation), which is a neodymium magnet having a magnetic force of about 4000 Gauss, is used as the first magnet member 21 and the second magnet member 23, the user holds the first grip 14 and the second grip. It is preferable that the gap between the first magnet member 21 and the second magnet member 23 is 1 mm or less in a state where the portion 15 is gripped. When the gap is set in this way, the first magnet member 21 and the second magnet member 23 are strongly repelled when the user grips the first grip 14 and the second grip 15, so the first press contact portion It is possible to obtain a force sufficient to separate 11 and the second pressure contact portion 12 from each other.
本実施形態に係るヒートシーラー１０では、上述の通り、従来のように付勢部材としてばね部材ではなく、互いに反発する第１磁石部材２１及び第２磁石部材２３を用いており、これらは接触しないように配置されている。このため、本発明に係るヒートシーラー１０を繰り返し使用しても、第１磁石部材２１及び第２磁石部材２３が磨耗することはない。従って、金属屑が発生することがなく、被シール部材内において望まれない混入物が入り込み、コンタミネーションが起こることを防止できる。 In the heat sealer 10 according to the present embodiment, as described above, the first magnet member 21 and the second magnet member 23 that repel each other are used as the biasing member instead of the spring member as in the related art, and these do not contact each other. Are arranged as follows. For this reason, even if the heat sealer 10 according to the present invention is repeatedly used, the first magnet member 21 and the second magnet member 23 are not worn. Therefore, metal waste is not generated, and it is possible to prevent unwanted contaminants from entering the sealed member and causing contamination.
また、本実施形態に係るヒートシーラー１０において、第１圧接部１１及び第２圧接部１２のそれぞれの長手方向の両端面（図１で示す面及びその面と反対側の面）を除く４つの面には複数のスリット１１ｂ、１２ｂが設けられている（図３及び図４を参照）。但し、被シール物に直接接触する突出部１１ａ、１２ａには、スリット１１ｂ、１２ｂは設けられない。このようなスリット１１ｂ、１２ｂが設けられることにより、第１圧接部１１及び第２圧接部１２によって被シール物を挟み込む際に、被シール物が第１圧接部１１及び第２圧接部１２の陰に隠れても、スリット１１ｂ、１２ｂにより被シール物を目視できる。このため、被シール物を挟み込む操作をより正確に行うことが可能となる。 Further, in the heat sealer 10 according to the present embodiment, four excluding both longitudinal end faces (the surface shown in FIG. 1 and the surface opposite to the surface) of each of the first press contact portion 11 and the second press contact portion 12. The surface is provided with a plurality of slits 11b and 12b (see FIGS. 3 and 4). However, the slits 11b and 12b are not provided in the protruding portions 11a and 12a that directly contact the objects to be sealed. By providing such slits 11 b and 12 b, when the object to be sealed is sandwiched between the first pressure contact part 11 and the second pressure contact part 12, the object to be sealed is behind the first pressure contact part 11 and the second pressure contact part 12. Even if hidden, the object to be sealed can be visually observed through the slits 11b and 12b. For this reason, it becomes possible to perform more accurately the operation of sandwiching the object to be sealed.
また、本実施形態に係るヒートシーラー１０において、第２台座部２２の第２磁石部材２３を設けた面と反対の面の中央にランプ２４が設けられている。このランプ２４は、後に説明するが、ヒータ１３の加熱に対応して点灯するように構成されている。 In the heat sealer 10 according to the present embodiment, the lamp 24 is provided at the center of the surface opposite to the surface on which the second magnet member 23 of the second pedestal portion 22 is provided. As will be described later, the lamp 24 is configured to light up in response to the heating of the heater 13.
次に、本実施形態に係るヒートシーラー１０において、被シール物を熱溶着させるために第１圧接部１１及び第２圧接部１２を加熱する構成について説明する。 Next, the structure which heats the 1st press-contact part 11 and the 2nd press-contact part 12 in order to heat-seal a to-be-sealed object in the heat sealer 10 which concerns on this embodiment is demonstrated.
上述の通り、第１圧接部１１及び第２圧接部１２は中空体であり、それらの内部には第１圧接部１１及び第２圧接部１２を加熱するためのヒータ１３が設けられている。また、ヒートシーラー１０は、ヒータ１３を電源と接続するための、電源コード（図示せず）を備えている。 As described above, the first pressure contact portion 11 and the second pressure contact portion 12 are hollow bodies, and a heater 13 for heating the first pressure contact portion 11 and the second pressure contact portion 12 is provided therein. Further, the heat sealer 10 includes a power cord (not shown) for connecting the heater 13 to a power source.
