Description

太陽電池モジュールのラミネート装置Solar cell module laminating equipment
　本発明は、太陽電池モジュールのラミネート装置に関する。 The present invention relates to a solar cell module laminating apparatus.
　太陽光発電に用いられる一般的な太陽電池モジュールは、表面保護材と裏面保護材との間に充填材を介して太陽電池セルを挟み込み、加熱及びラミネート（挟圧）することにより製造される。 A general solar battery module used for photovoltaic power generation is manufactured by sandwiching a solar battery cell between a surface protective material and a back surface protective material via a filler, and heating and laminating (squeezing pressure).
　表面保護材には、一般にガラス板やプラスチック板等が用いられる。そして裏面保護材には、フッ素樹脂フィルム、ポリエチレンテレフタレート（polyethylene terephthalate、以下、ＰＥＴと略す）樹脂フィルム、ガラス板、プラスチック板等が用いられ、充填材にはエチレンビニルアセテート（ethylene vinyl acetate、以下、ＥＶＡと略す）樹脂等が用いられる。 Generally, a glass plate or a plastic plate is used as the surface protective material. The back surface protective material is a fluororesin film, a polyethylene terephthalate (hereinafter abbreviated as PET) resin film, a glass plate, a plastic plate, etc., and the filler is ethylene vinyl acetate (ethylene vinyl acetate, hereinafter, Resin or the like is used.
　特に、建材一体型太陽電池（Building Integrated Photovoltaic Module、以下、ＢＩＰＶと略す）や、Heterojunction with Intrinsic Thin-layer（以下、ＨＩＴ（登録商標）と略す）のような両面受光型太陽電池モジュールの保護材には、表面と裏面の両方にガラス板やプラスチック板が用いられる。以下、このような構造をダブルガラス構造と称する。ここで、ダブルガラス構造では、両面に用いられるガラス板やプラスチック板の板厚がフッ素樹脂フィルムやＰＥＴ樹脂フィルムよりも厚いため、ラミネート時の加熱時間が長くなる傾向がある。 In particular, protective materials for double-sided photovoltaic modules such as building-integrated photovoltaic modules (hereinafter abbreviated as BIPV) and heterojunction with intrinsic-thin-layer (hereinafter abbreviated as HIT (registered trademark)). A glass plate or a plastic plate is used for both the front and back surfaces. Hereinafter, such a structure is referred to as a double glass structure. Here, in the double glass structure, since the plate thickness of the glass plate or plastic plate used on both sides is thicker than that of the fluororesin film or PET resin film, the heating time during lamination tends to be longer.
　以下に記載する特許文献１には、押圧中に太陽電池モジュールに接触可能で、かつ従来のプレス機のプレス部材の材料、例えばゴム等に比べて熱伝導率が高い材料、例えば金属等を用いたヒータで太陽電池モジュールを押圧することにより、太陽電池モジュールを裏面側からも加熱するラミネート装置が記載されている。なお、通常のラミネート装置においては、太陽電池モジュールは表面が下方を向くように熱板上に載置されてラミネートされる。 Patent Document 1 described below uses a material such as a metal that can contact the solar cell module during pressing and has a higher thermal conductivity than a material of a press member of a conventional press machine, such as rubber. A laminating apparatus is described in which a solar cell module is also heated from the back side by pressing the solar cell module with a heater. In a normal laminating apparatus, the solar cell module is placed and laminated on a hot plate so that the surface faces downward.
特許５０６８８００号公報Japanese Patent No. 5068800
　しかしながら、特許文献１に記載されたラミネート装置は、第１のプレス部分３と第２のプレス部分４とが閉じた後で、ヒータ５０がシリンダ１０によりソーラーモジュール２に対して下降するために、第１のプレス部分３と、ヒータ５０とをそれぞれ別々に駆動する機構が必要であった。また、駆動機構としてシリンダを用いており、均一にプレスするための制御が大変困難であった。 However, in the laminating apparatus described in Patent Document 1, the heater 50 is lowered with respect to the solar module 2 by the cylinder 10 after the first press portion 3 and the second press portion 4 are closed. A mechanism for separately driving the first press portion 3 and the heater 50 was required. In addition, a cylinder is used as a drive mechanism, and it is very difficult to control for uniform pressing.
　本発明は上記事情に鑑み、小型かつ安価な機構で太陽電池モジュールを高速に均一にラミネートすることが可能な太陽電池モジュールのラミネート装置を提供することを目的とする。 In view of the above circumstances, an object of the present invention is to provide a solar cell module laminating apparatus capable of uniformly laminating solar cell modules at high speed with a small and inexpensive mechanism.

FIG. 3 is a longitudinal sectional view taken along line CC of FIG. Is shown in FIG.
　また、ラミネート装置１の熱板２０上に載置された被ラミネート体２の断面構成を図５に示す。この被ラミネート体２は、両面がガラス板で保護されたダブルガラス構造の太陽電池モジュールであって、ガラス板から成る表面保護材２ａ、充填材２ｂ１、太陽電池セル２ｃ、充填材２ｂ２、ガラス板から成る裏面保護材２ｄが順に積層された構成を備え、熱板２０の上でラミネートされる。なお、被ラミネート体２の厚みをｔとする。 FIG. 5 shows a cross-sectional configuration of the laminated body 2 placed on the hot plate 20 of the laminating apparatus 1. The laminated body 2 is a solar cell module having a double glass structure in which both surfaces are protected by glass plates, and includes a surface protecting material 2a made of a glass plate, a filler 2b1, solar cells 2c, a filler 2b2, and a glass plate. The back surface protective material 2d made of is laminated on the hot plate 20 in order. Note that the thickness of the laminate 2 is t.
　図１～図４に示されたラミネート装置１は、被ラミネート体２を図５の矢印Ｙで示されたように上からプレス及び加熱するための上ヒータ１１を内蔵したプレスプレート１０と、下から支持及び加熱するための下ヒータ２１を内蔵した熱板２０とを備える。なお、図１に示されたように、ラミネート装置１は、全体の動作を制御するため中央処理制御部６０を備える。この中央処理制御部６０により、後述する上ヒータ１１、下ヒータ２１、昇降機１２、膨張性シール１３へ空気を送り込むコンプレッサ１３ａ、剥離シート移動機構１７、搬送シート移動機構２４、搬入コンベア４０、搬出コンベア５０のそれぞれの動作が制御される。 A laminating apparatus 1 shown in FIGS. 1 to 4 includes a press plate 10 having a built-in upper heater 11 for pressing and heating a laminate 2 from above as indicated by an arrow Y in FIG. And a hot plate 20 incorporating a lower heater 21 for supporting and heating. As shown in FIG. 1, the laminating apparatus 1 includes a central processing control unit 60 for controlling the entire operation. By this central processing control unit 60, an upper heater 11, a lower heater 21, an elevator 12, a compressor 13a for sending air to the inflatable seal 13, a release sheet moving mechanism 17, a conveying sheet moving mechanism 24, a carry-in conveyor 40, and a carry-out conveyor Each of the 50 operations is controlled.
　図２に示されたように、プレスプレート１０は、上フレーム１４の下面側に固定されている。上フレーム１４は、シリンダ１２ａで上下方向に駆動される昇降機１２で支持されており、上下に移動する。この昇降機１２は、図１に示されるようにラミネート装置１の４隅にそれぞれ配置される。しかし、上フレーム１４を均等に支持することが可能であれば必ずしも４隅に配置される必要はなく、また上フレーム１４を上下に駆動可能であれば他の機構でもよい。 2, the press plate 10 is fixed to the lower surface side of the upper frame 14. The upper frame 14 is supported by the elevator 12 driven in the vertical direction by the cylinder 12a, and moves up and down. The elevators 12 are respectively disposed at the four corners of the laminating apparatus 1 as shown in FIG. However, it is not always necessary to dispose the upper frame 14 at the four corners as long as the upper frame 14 can be supported uniformly, and other mechanisms may be used as long as the upper frame 14 can be driven up and down.
　一方、熱板２０は、図２に示されたように、下フレーム２２の上側に固定されている。 On the other hand, the hot plate 20 is fixed to the upper side of the lower frame 22 as shown in FIG.
　上フレーム１４には、その周縁部下面１４ａに、上フレーム１４と下フレーム２２との間を密閉するためのシール部材として、膨張性を有する膨張性シール１３が嵌め込まれている。また、上フレーム１４における任意の位置に吸排気口１８が設けられており、図示されない真空ポンプに接続されている。なお、吸排気口１８は、上フレーム１４の代わりに下フレーム２２に設けてもよく、あるいは上フレーム１４及び下フレーム２２の両方に設けてもよい。 The upper frame 14 is fitted with an expandable seal 13 having expandability as a seal member for sealing the space between the upper frame 14 and the lower frame 22 on the lower surface 14a of the peripheral edge portion. An intake / exhaust port 18 is provided at an arbitrary position in the upper frame 14 and connected to a vacuum pump (not shown). The intake / exhaust port 18 may be provided in the lower frame 22 instead of the upper frame 14, or may be provided in both the upper frame 14 and the lower frame 22.
　また、プレスプレート１０の下面には、シリコーンゴム等の弾性材料から成る緩衝材１５が全面に貼り付けられている。これにより、プレスプレート１０によって、被ラミネート体２の裏面の一部に過度な加重が印加されて破損する事態が回避される。 Further, a cushioning material 15 made of an elastic material such as silicone rubber is attached to the entire lower surface of the press plate 10. As a result, the press plate 10 avoids a situation in which an excessive load is applied to a part of the back surface of the laminate 2 and is damaged.
　図４に示されたように、下フレーム２２の長手方向の一端側には、被ラミネート体２をラミネート装置１内へ搬入する搬入コンベア４０が設けられ、他端側には、ラミネート後にラミネート装置１から搬出された被ラミネート体２を受け取る搬出コンベア５０が設けられている。 As shown in FIG. 4, a carry-in conveyor 40 for carrying the object to be laminated 2 into the laminating apparatus 1 is provided on one end side in the longitudinal direction of the lower frame 22, and a laminating apparatus after lamination on the other end side. A carry-out conveyor 50 for receiving the laminate 2 carried out from 1 is provided.
　図１、図４に示された搬送シート２３は、被ラミネート体２を熱板２０上で長手方向に移動する。さらに搬送シート２３は、ラミネート中に熱により溶融して被ラミネート体２から漏れ出した充填材により熱板２０が汚れることを防止する。そして搬送シート２３は、ローラ等を含む搬送シート移動機構２４により下フレーム２２の上方及び下方を循環するように移動する。 1 and 4 moves the laminate 2 in the longitudinal direction on the hot plate 20. Further, the conveying sheet 23 prevents the hot plate 20 from being soiled by the filler that has melted by heat during the lamination and leaked from the laminate 2. The transport sheet 23 is moved so as to circulate above and below the lower frame 22 by a transport sheet moving mechanism 24 including rollers and the like.
　図示されない駆動機構により搬送シート移動機構２４が駆動され、搬送シート２３が移動することで、搬入コンベア４０から搬入された被ラミネート体２を搬送シート２３が受け取って熱板２０上へ配置する。 The transport sheet moving mechanism 24 is driven by a drive mechanism (not shown), and the transport sheet 23 is moved, so that the transport target sheet 2 received from the carry-in conveyor 40 is received by the transport sheet 23 and placed on the hot plate 20.
　ラミネート後は、搬送シート２３が被ラミネート体２を熱板２０の上から搬出コンベア５０へ搬出する。なお、搬送シート２３における任意の位置に図示されないクリーニング機構を設けてクリーニングを行うことにより、搬送シート２３の汚れていない部分を常に使用することが可能となる。 After lamination, the conveyance sheet 23 carries the laminated body 2 from the hot plate 20 to the carry-out conveyor 50. In addition, by providing a cleaning mechanism (not shown) at an arbitrary position on the transport sheet 23 to perform cleaning, it is possible to always use a non-stained portion of the transport sheet 23.
　図４に示された剥離シート１６は、ラミネート後の被ラミネート体２を緩衝材１５から剥離しやすくするものである。さらに剥離シート１６は、ラミネート中に熱により溶融して被ラミネート体２から漏れ出した充填材によって、緩衝材１５が汚れることを防止するためのものでもある。剥離シート１６は、ローラ等を含む剥離シート移動機構１７により、上フレーム１４の上方及び下方を循環するように移動する。 The release sheet 16 shown in FIG. 4 facilitates the release of the laminated body 2 after lamination from the buffer material 15. Further, the release sheet 16 is also for preventing the buffer material 15 from being soiled by the filler that has melted due to heat during the lamination and leaked from the laminate 2. The release sheet 16 is moved so as to circulate above and below the upper frame 14 by a release sheet moving mechanism 17 including a roller and the like.
　図示されない駆動機構により剥離シート移動機構１７が駆動されて剥離シート１６が移動し、また剥離シート１６における任意の位置に図示されないクリーニング機構を設けてクリーニングを行うことにより、剥離シート１６の汚れていない部分を常に使用することができる。 The release sheet moving mechanism 17 is driven by a drive mechanism (not shown) to move the release sheet 16, and a cleaning mechanism (not shown) is provided at any position on the release sheet 16 to perform cleaning so that the release sheet 16 is not soiled. You can always use pieces.
　ここで、搬送シート２３と剥離シート１６は、ともに伝熱性及び耐熱性を有する素材として、例えばガラスクロスシート等を用いて形成してもよい。また、充填材を剥離しやすくするために、搬送シート２３と剥離シート１６の表面には、例えばフッ素樹脂コーティングが施されることが望ましい。 Here, both the transport sheet 23 and the release sheet 16 may be formed using, for example, a glass cloth sheet or the like as a material having heat conductivity and heat resistance. Moreover, in order to make it easy to peel off the filler, it is desirable that the surfaces of the transport sheet 23 and the release sheet 16 be coated with, for example, a fluororesin.
　なお、プレスプレート１０と熱板２０は、ともに伝熱性及び耐熱性の高い素材として、例えばアルミニウムや鉄等の金属を用いて形成してもよい。 Note that both the press plate 10 and the hot plate 20 may be formed using a metal such as aluminum or iron as a material having high heat transfer and heat resistance.
　また、プレスプレート１０と熱板２０の内部には、それぞれ短手方向に沿って水平に複数の孔が形成されている。これらの孔には、棒状の電気ヒータとして上ヒータ１１と下ヒータ２１とが嵌め込まれている。 Also, a plurality of holes are formed in the press plate 10 and the hot plate 20 horizontally along the short direction. In these holes, an upper heater 11 and a lower heater 21 are fitted as rod-shaped electric heaters.
　なお、被ラミネート体２を加熱する手段の構成は、このような上ヒータ１１、下ヒータ２１には限定されず、被ラミネート体２を均一に加熱できるものであれば他の構成によるものであってもよい。 The configuration of the means for heating the laminate 2 is not limited to the upper heater 11 and the lower heater 21 as long as the laminate 2 can be uniformly heated. May be.
　膨張性シール１３は、図１、図２に示されたように、上フレーム１４の周縁部下面１４ａに形成した四角形の溝内に、シリコーンゴム等の弾性体から成るチューブ状の部材を接着剤等で接合して形成される。 As shown in FIGS. 1 and 2, the inflatable seal 13 is a tube-shaped member made of an elastic material such as silicone rubber in a rectangular groove formed in the lower surface 14 a of the peripheral edge of the upper frame 14. Etc. are formed by joining.
　膨張性シール１３は、図１に示されたようにコンプレッサ１３ａに接続されており、コンプレッサ１３ａからの圧縮空気を内部に注入されて膨張する。なお、膨張性シール１３における空気の入口において、図示されていないレギュレータを接続し、膨張性シール１３内の圧力が所望の値を維持するように監視しながら膨張性シール１３の圧力を制御してもよい。 The inflatable seal 13 is connected to the compressor 13a as shown in FIG. 1, and expands by injecting compressed air from the compressor 13a into the interior. A regulator (not shown) is connected to the air inlet of the expandable seal 13 to control the pressure of the expandable seal 13 while monitoring the pressure in the expandable seal 13 to maintain a desired value. Also good.
　図６に示されたように、下フレーム２２の周縁部上面と熱板２０の上面との高さ方向の位置は同一である。上フレーム１４の周縁部下面１４ａと緩衝材１５の下面の高さの差分ｙと、膨張性シール１３の高さｈとの和ｙ＋ｈが、被ラミネート体２の厚みｔより隙間ｇだけ大きくなるように、即ちｙ＋ｈ＝ｔ＋ｇが成立するように、上フレーム１４の周縁部下面１４ａと緩衝材１５の下面の高さの差分ｙを設定する。これにより、緩衝材１５の下面が被ラミネート体２の上面に接触しない状態となる。 As shown in FIG. 6, the height direction positions of the upper surface of the peripheral edge of the lower frame 22 and the upper surface of the hot plate 20 are the same. The sum y + h of the height difference y between the lower peripheral surface 14a of the upper frame 14 and the lower surface of the cushioning material 15 and the height h of the inflatable seal 13 is larger than the thickness t of the laminate 2 by a gap g. In other words, the height difference y between the lower surface 14a of the peripheral edge portion of the upper frame 14 and the lower surface of the cushioning material 15 is set so that y + h = t + g is established. Thereby, the lower surface of the cushioning material 15 is not in contact with the upper surface of the laminate 2.
　ここで、例えば膨張性シール１３の高さｈが１２ｍｍであるとする。被ラミネート体２の上面と緩衝材１５の下面との間の隙間ｇは、５ｍｍ以上であることが望ましい。ダブルガラス型の被ラミネート体２の厚さｔは、一般に６～１２ｍｍである。そこで、被ラミネート体２の厚さｔが最大値１２ｍｍであるときに、５ｍｍの隙間ｇが確保されるように考慮すればよい。そこで、上述した式ｙ＋ｈ＝ｔ＋ｇが成立するように、上フレーム１４の周縁部下面１４ａと緩衝材１５の下面の高さの差分ｙを５ｍｍに設定すればよい。 Here, for example, it is assumed that the height h of the expandable seal 13 is 12 mm. The gap g between the upper surface of the laminate 2 and the lower surface of the cushioning material 15 is desirably 5 mm or more. The thickness t of the double glass type laminate 2 is generally 6 to 12 mm. Therefore, it may be considered that a gap g of 5 mm is secured when the thickness t of the laminate 2 is a maximum value of 12 mm. Therefore, the height difference y between the peripheral portion lower surface 14a of the upper frame 14 and the lower surface of the cushioning material 15 may be set to 5 mm so that the above-described expression y + h = t + g is satisfied.
　次に、本実施の形態によるラミネート装置１を用いて被ラミネート体２にラミネート加工を行う際の手順の一例について説明する。なお、以下の説明で用いる図７～図１０には、被ラミネート体２を例示として１枚のみ示す。しかし、本実施の形態によるラミネート装置１によれば、複数の被ラミネート体２を同時にラミネートすることも可能である。 Next, an example of a procedure for laminating the object to be laminated 2 using the laminating apparatus 1 according to this embodiment will be described. In FIGS. 7 to 10 used in the following description, only one laminated body 2 is shown as an example. However, according to the laminating apparatus 1 according to the present embodiment, it is possible to laminate a plurality of laminates 2 simultaneously.
　先ず、図７に示されるように、被ラミネート体２を搬入コンベア４０からラミネート装置１内へ矢印Ｘ１の方向に搬入する。さらに、搬送シート２３を移動して被ラミネート体２を熱板２０の上に配置する。このとき、上フレーム１４と下フレーム２２とが開放状態になるように、昇降機１２により上フレーム１４を上昇させた後支持する。 First, as shown in FIG. 7, the object to be laminated 2 is carried from the carry-in conveyor 40 into the laminating apparatus 1 in the direction of the arrow X1. Furthermore, the conveyance sheet 23 is moved to arrange the laminated body 2 on the hot plate 20. At this time, the upper frame 14 is lifted and supported by the elevator 12 so that the upper frame 14 and the lower frame 22 are opened.
　図８に示されるように、上フレーム１４と下フレーム２２との間が膨張性シール１３で密閉されるような高さまで、昇降機１２により上フレーム１４を下降させる。上フレーム１４と下フレーム２２との間に形成されたチャンバ３０内を、図示されていない真空ポンプにより吸排気口１８から真空引きする。 As shown in FIG. 8, the upper frame 14 is lowered by the elevator 12 to such a height that the space between the upper frame 14 and the lower frame 22 is sealed with the expandable seal 13. The inside of the chamber 30 formed between the upper frame 14 and the lower frame 22 is evacuated from the intake / exhaust port 18 by a vacuum pump (not shown).
　これにより、チャンバ３０内の気圧が大気圧より低下し、上フレーム１４にかかる大気圧との間に圧力差が生じて、プレスプレート１０が下方向へ引っ張られる。しかし、この方向とは逆の上方向に昇降機１２の支持力が作用し、プレスプレート１０は高さを維持する。このため、膨張性シール１３が押し潰されて緩衝材１５の下面が被ラミネート体２の上面に接触する事態は回避される。 Thereby, the atmospheric pressure in the chamber 30 is lowered from the atmospheric pressure, and a pressure difference is generated between the atmospheric pressure applied to the upper frame 14 and the press plate 10 is pulled downward. However, the support force of the elevator 12 acts in the upward direction opposite to this direction, and the press plate 10 maintains the height. For this reason, the situation where the expandable seal 13 is crushed and the lower surface of the cushioning material 15 contacts the upper surface of the laminate 2 is avoided.
　なお、真空引きが完了しない状態で緩衝材１５が被ラミネート体２に接触した場合は、プレスプレート１０からの熱により溶融した充填材に気泡が発生する。この結果、完成した太陽電池モジュールに気泡が残留し、発電効率低下や外観の悪化の原因となる。 In addition, when the buffer material 15 contacts the laminated body 2 in a state where evacuation is not completed, bubbles are generated in the filler that is melted by the heat from the press plate 10. As a result, bubbles remain in the completed solar cell module, causing a reduction in power generation efficiency and a deterioration in appearance.
　真空引きが完了すると、図９に示されるように、昇降機１２を下降させて上フレーム１４の支えを解除する。これにより、チャンバ３０内の気圧と上フレーム１４にかかる大気圧との差とにより、プレスプレート１０が下方向へ引っ張られる。これにより、膨張性シール１３が押し潰されて、熱板２０とプレスプレート１０との間で被ラミネート体２がプレスされる。このとき、プレスプレート１０に上ヒータ１１が内蔵されているため、被ラミネート体２を裏面側からも確実に加熱して高速にラミネートすることができる。なお、チャンバ３０内を真空ポンプにより真空に近づくまで引いた場合、大気圧（１ｋｇ／ｃｍ２）分の圧力が下方へ作用する。 When the evacuation is completed, as shown in FIG. 9, the elevator 12 is lowered to release the support of the upper frame 14. Thereby, the press plate 10 is pulled downward by the difference between the atmospheric pressure in the chamber 30 and the atmospheric pressure applied to the upper frame 14. As a result, the expandable seal 13 is crushed and the laminate 2 is pressed between the hot plate 20 and the press plate 10. At this time, since the upper heater 11 is built in the press plate 10, the laminate 2 can be reliably heated from the back side and laminated at high speed. In addition, when the inside of the chamber 30 is pulled until it approaches a vacuum by a vacuum pump, a pressure corresponding to the atmospheric pressure (1 kg / cm 2 ) acts downward.
　予め設定された時間このプレス状態を保持することで、被ラミネート体２が熱板２０とプレスプレート１０との間で加熱及びラミネートされて、太陽電池モジュールが形成される。 By holding this pressed state for a preset time, the object to be laminated 2 is heated and laminated between the hot plate 20 and the press plate 10 to form a solar cell module.
　最後に、吸排気口１８から大気を導入し、図１０に示されるように、昇降機１２により上フレーム１４を持ち上げて上フレーム１４と下フレーム２２との間を開放する。搬送シート２３を移動して、完成した太陽電池モジュールを搬出コンベア５０へ矢印Ｘ２の方向に搬出する。 Finally, air is introduced from the intake / exhaust port 18 and the upper frame 14 is lifted by the elevator 12 to open the space between the upper frame 14 and the lower frame 22 as shown in FIG. The transport sheet 23 is moved, and the completed solar cell module is transported to the transport conveyor 50 in the direction of the arrow X2.
　以上説明したように、本発明の実施の形態によれば、ダブルガラス構造を有する太陽電池モジュールを裏面側からも確実に加熱して高速にラミネートすることができる。また、ヒータを内蔵したプレスプレートと上フレームとを、大気圧との差により生じる圧力で一体化して駆動することで、装置の駆動部の部品点数を減らし小型かつ安価な構造にするとともに、均一にプレスすることができる。 As described above, according to the embodiment of the present invention, a solar cell module having a double glass structure can be reliably heated from the back side and laminated at high speed. In addition, the press plate with a built-in heater and the upper frame are integrated and driven by the pressure generated by the difference from the atmospheric pressure, thereby reducing the number of parts in the drive part of the device and making it compact and inexpensive, and uniform. Can be pressed.
　本発明の実施の形態について説明したが、この実施の形態は例として提示したものであり、発明の技術的範囲を限定することは意図していない。この新規な実施の形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。上記実施の形態及びその変形は、発明の技術的範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。 Although the embodiment of the present invention has been described, this embodiment is presented as an example, and is not intended to limit the technical scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.

However, the position where the expandable seal 13 is provided is not limited to the end surface on the lower surface side of the upper frame 14, and may be the end surface on the upper surface side of the lower frame 22.
