Description

本発明は、リボンデッド製品の製造方法及びそれに用いるリボンデッド製品の製造装置に関する。更に詳しくは、湿気硬化型の接着剤を過熱蒸気により硬化させてポリウレタンフォーム等のチップ間を接合するリボンデッド製品の製造方法及びそれに用いるリボンデッド製品の製造装置に関する。
本発明は、シート、フロアーマット、パット、アームレスト、芯材、嵩上げ材等の車両用内装材、家具、建材、緑化用マット、土壌代替材などの各種の用途において利用することができる。
The present invention relates to a method for manufacturing a ribbon dead product and an apparatus for manufacturing a ribbon dead product used therefor. More specifically, the present invention relates to a method for manufacturing a ribbon dead product in which a moisture curing type adhesive is cured by superheated steam to join chips such as polyurethane foam, and a ribbon dead product manufacturing apparatus used therefor.
INDUSTRIAL APPLICABILITY The present invention can be used in various applications such as vehicle interior materials such as seats, floor mats, pads, armrests, core materials, and raising materials, furniture, building materials, greening mats, soil substitute materials, and the like.

車両用シートクッション等の車両用内装材などのリボンデッド製品は、従来より、ポリウレタンフォームのチップ等を加熱硬化型の接着剤及び湿気硬化型の接着剤等の各種の接着剤により接合することにより製造されている。加熱硬化型の接着剤は、それぞれの種類によって、温風加熱、高周波加熱、熱板との接触による加熱等の所定の方法により加熱し、硬化させることができる。しかし、温風加熱では、圧縮空気を生成させる設備及び圧縮空気の熱膨張に対応する設備を必要とし、コスト高となる傾向があり、また、内部まで十分に加熱することが容易ではないという問題もある。更に、高周波加熱では、発熱が被加熱体の中心部に集中する傾向があり、熱を均一に分散させることができず、均質な製品を製造することができないことがある。また、熱板との接触による加熱では、発熱体が被加熱体と直接接触するため表面が劣化することがある。
一方、湿気硬化型の接着剤は、飽和蒸気等の水蒸気と接触させることにより硬化させる方法が一般的である(例えば、特許文献1参照。)。
Ribbon dead products such as vehicle interior cushions such as vehicle seat cushions are conventionally made by joining polyurethane foam chips, etc. with various adhesives such as heat-curing adhesives and moisture-curing adhesives. It is manufactured. The thermosetting adhesive can be heated and cured by a predetermined method such as warm air heating, high-frequency heating, or heating by contact with a hot plate, depending on the type. However, hot air heating requires equipment that generates compressed air and equipment that supports thermal expansion of compressed air, which tends to increase costs, and that it is not easy to sufficiently heat the inside. There is also. Furthermore, in high-frequency heating, heat generation tends to concentrate at the center of the object to be heated, so that heat cannot be uniformly distributed and a homogeneous product may not be manufactured. Further, in the heating by contact with the hot plate, the surface may be deteriorated because the heating element is in direct contact with the heated object.
On the other hand, moisture curing type adhesives are generally cured by bringing them into contact with water vapor such as saturated steam (see, for example, Patent Document 1).

You can use what you want. These ketimine compounds may be used alone or in combination of two or more.
The one-pack type epoxy adhesive contains at least one of a plasticizer, a filler, a silane coupling agent, an antioxidant, a pigment and the like as in the case of the one-pack type polyurethane adhesive. May be.

湿気硬化型の接着剤の含有量は特に限定されないが、チップ混合物と接着剤との合計を100質量%とした場合に、5〜30質量%、特に8〜15質量%であることが好ましい。接着剤の含有量が5質量%未満であると、チップ間が十分に接合されず、チップが脱落することがあるため好ましくない。一方、30質量%を越えると、接着剤が過剰となり、クッション性等のリボンデッド製品の物性等が低下することがあるため好ましくない。   The content of the moisture curable adhesive is not particularly limited, but is preferably 5 to 30% by mass, particularly 8 to 15% by mass when the total of the chip mixture and the adhesive is 100% by mass. When the content of the adhesive is less than 5% by mass, the chips are not sufficiently bonded to each other, and the chips may fall off, which is not preferable. On the other hand, if it exceeds 30% by mass, the adhesive becomes excessive and the physical properties of the ribbon dead product such as cushioning properties may be deteriorated.

チップ混合物と湿気硬化型の接着剤とを含有する上記「リボンデッド原料」には、リボンデッド製品の特性を大きく損なうことのない他の成分、例えば、抗菌剤、難燃剤等が含まれていてもよい。この第3成分の含有量は、リボンデッド製品の個々の用途に必要とされる物性、即ち、クッション性、抗菌性、難燃性等が大きく低下しない程度に限定され、リボンデッド原料を100質量%とした場合に、20質量%以下、特に10質量%以下とすることができる。   The above-mentioned “ribbon dead raw material” containing a chip mixture and a moisture curable adhesive contains other components that do not significantly impair the properties of the ribbon dead product, such as antibacterial agents and flame retardants. Also good. The content of the third component is limited to such an extent that the physical properties required for individual applications of the ribbon dead product, that is, cushioning properties, antibacterial properties, flame retardancy, etc., are not significantly reduced. %, It can be 20% by mass or less, particularly 10% by mass or less.

上記「成形型」の形状及び構造は特に限定されないが、型本体と上型とを備え、これらの型の内面間に各々のリボンデッド製品の形状に応じたキャビティが形成される。また、型本体には過熱蒸気を供給するための供給口と、成形後、温水をドレンとして排出するための排出口とが設けられる。この成形型には過熱蒸気が供給されるため、型本体及び上型は耐熱性と防錆性とを備えていることが好ましい。型本体及び上型は、通常、金属により形成され、特にステンレス鋼、アルミニウム等により形成されていることが好ましい。また、チップの材質等によっては、型の内表面等を耐熱性、耐腐食性等に優れた金属、セラミック等によりコーティングすることもできる。   The shape and structure of the “molding die” are not particularly limited, but include a die body and an upper die, and cavities corresponding to the shapes of the ribbon dead products are formed between the inner surfaces of these die. The mold body is provided with a supply port for supplying superheated steam and a discharge port for discharging hot water as a drain after molding. Since superheated steam is supplied to the mold, it is preferable that the mold body and the upper mold have heat resistance and rust resistance. The mold body and the upper mold are usually formed of metal, and are preferably formed of stainless steel, aluminum or the like. Depending on the material of the chip, the inner surface of the mold can be coated with a metal, ceramic or the like having excellent heat resistance and corrosion resistance.

上記「充填」は、チップ混合物に湿気硬化型の接着剤を塗布し、この接着剤が塗布されたチップ混合物、即ち、リボンデッド原料を型本体に投入し、その後、必要に応じて、油圧シリンダー、エアシリンダー、作業者が手でならす等により押圧してリボンデッド原料を所定圧で加圧し、次いで、上型を配置することにより行うことができる。チップ混合物に接着剤を塗布する方法は特に限定されないが、接着剤を均等に塗布するためにはスプレーガン等による吹き付け塗布が好ましい。また、接着剤の粘度が高い場合は、加温して塗布することもできる。   In the above-mentioned “filling”, a moisture-curing adhesive is applied to the chip mixture, and the chip mixture to which the adhesive is applied, that is, a ribbon dead raw material is put into the mold body. It is possible to press the ribbon dead raw material at a predetermined pressure by pressing it with an air cylinder or an operator, and then disposing the upper die. The method of applying the adhesive to the chip mixture is not particularly limited, but spray coating with a spray gun or the like is preferable in order to apply the adhesive evenly. Moreover, when the viscosity of an adhesive agent is high, it can also heat and apply | coat.

リボンデッド原料を成形型に充填した後、成形型に過熱蒸気が供給され、リボンデッド原料と過熱蒸気とが接触し、この原料に含有される接着剤が硬化し、各々のチップ間が接合される。
上記「過熱蒸気」は飽和蒸気が更に加熱されて生成する蒸気である。この過熱蒸気は低圧の飽和蒸気を使用して生成させることができ、飽和蒸気は低圧であるほど熱伝導性に優れるため、容易に高温の過熱蒸気を生成させることができる。そのため、過熱蒸気を用いる場合に、その生成に使用される蒸気発生のためのボイラーを増設する必要もなく、コスト面でも有利である。また、過熱蒸気は高温における熱伝導性に優れるため、製品全体に渡って接着剤の硬化が促進され、均質なリボンデッド製品とすることができる。
After filling the ribbon die raw material into the mold, superheated steam is supplied to the mold, the ribbon dead raw material and the superheated steam come into contact with each other, the adhesive contained in this raw material is cured, and the chips are joined together. The
The “superheated steam” is steam generated by further heating saturated steam. This superheated steam can be generated using low-pressure saturated steam. Since the saturated steam has a higher thermal conductivity as the pressure is lower, high-temperature superheated steam can be easily generated. For this reason, when superheated steam is used, it is not necessary to add a boiler for generating steam used for the production, which is advantageous in terms of cost. Moreover, since superheated steam is excellent in thermal conductivity at high temperature, curing of the adhesive is promoted over the entire product, and a homogeneous ribbon dead product can be obtained.

飽和蒸気を用いるリボンデッド製品の製造方法では、通常、0.1〜0.7MPaの圧力の飽和蒸気が使用されるが、0.01MPa以下の低圧の飽和蒸気を加熱することにより、0.1〜0.7MPaの圧力の飽和蒸気の温度に相当する温度、更にはそれを越える高温の過熱蒸気を容易に生成させることができる。このようにして生成する過熱蒸気に含まれる水分は、湿気硬化型の接着剤の硬化に必要な量を越えて過剰の水分を含む同温度の飽和蒸気に比べて少なく、製品の濡れが防止、又は少なくとも抑制され、かびの発生、加水分解等も抑えられる。但し、過熱蒸気は、高温になるに従って一定体積に含まれる水分量が少なくなるため、例えば、200℃以上の高温の過熱蒸気を用いる場合は、必要に応じて予めリボンデッド原料に水分を添加しておく等の対策が必要になる。   In the manufacturing method of the ribbon dead product using saturated steam, normally, saturated steam having a pressure of 0.1 to 0.7 MPa is used, but by heating saturated steam having a low pressure of 0.01 MPa or less, A temperature corresponding to the temperature of the saturated steam at a pressure of ˜0.7 MPa, and a high-temperature superheated steam exceeding it can be easily generated. The moisture contained in the superheated steam generated in this way is less than the amount required for the moisture-curing adhesive to cure, compared to saturated steam at the same temperature containing excess moisture, preventing the product from getting wet. Or at least it is suppressed and generation | occurrence | production of a mold | fungi, hydrolysis, etc. are also suppressed. However, since the amount of water contained in a certain volume decreases as the temperature of the superheated steam increases, for example, when using a superheated steam at a high temperature of 200 ° C. or higher, water is added to the ribbon dead raw material in advance as necessary. Measures such as keeping are necessary.

この過熱蒸気の温度は特に限定されないが、100℃以上且つチップ混合物に含まれるチップのうち最も低い温度で分解するチップの分解温度が100℃を越える場合に、その分解温度未満であることが好ましく、100〜250℃であることがより好ましい。過熱蒸気の温度が100℃未満であると、接着剤を十分に硬化させることができないことがある。一方、250℃を越えると、チップの熱分解は生じないにしても、過熱蒸気に含まれる水分が過少となり、接着剤を十分に硬化させることができない場合がある。また、過熱蒸気の温度は130〜200℃であることが特に好ましく、135〜195℃、特に145〜190℃、更に155〜185℃であることがより好ましい。過熱蒸気の温度が130〜200℃であれば、接着剤を短時間で硬化させることができ、リボンデッド製品を効率よく製造することができる。特に、過熱蒸気の温度が155〜185℃であれば、この過熱蒸気には接着剤の硬化に十分な量の水分が含まれており、且つ温度も十分に高いため、60秒以下、特に40秒以下、更に30秒以下の短時間で接着剤を硬化させることができ、リボンデッド製品をより効率よく製造することができる。   The temperature of the superheated steam is not particularly limited, but is preferably less than the decomposition temperature when the decomposition temperature of the chip that decomposes at 100 ° C or higher and the lowest temperature among the chips contained in the chip mixture exceeds 100 ° C. 100 to 250 ° C. is more preferable. If the temperature of the superheated steam is less than 100 ° C., the adhesive may not be sufficiently cured. On the other hand, if the temperature exceeds 250 ° C., the thermal decomposition of the chip does not occur, but the moisture contained in the superheated steam becomes insufficient, and the adhesive may not be sufficiently cured. The temperature of the superheated steam is particularly preferably 130 to 200 ° C, more preferably 135 to 195 ° C, particularly 145 to 190 ° C, and further preferably 155 to 185 ° C. If the temperature of superheated steam is 130-200 degreeC, an adhesive agent can be hardened in a short time and a ribbon dead product can be manufactured efficiently. In particular, if the temperature of the superheated steam is 155 to 185 ° C., the superheated steam contains a sufficient amount of moisture for curing the adhesive and the temperature is sufficiently high. The adhesive can be cured in a short time of not more than 2 seconds and not more than 30 seconds, and a ribbon dead product can be produced more efficiently.

更に、過熱蒸気の温度は、200℃以上且つチップ混合物に含まれるチップのうち最も低い温度で分解するチップの分解温度が200℃を越える場合に、その分解温度未満とすることもできる。但し、このように高温の過熱蒸気を用いる場合は、過熱蒸気に含まれる水分量が少ないため、予め水が添加されたリボンデッド原料を使用する必要がある。この水はリボンデッド原料を調製するときに添加する、即ち、配合される各々の成分を混合する工程で所定量を添加してもよい。また、調製後のリボンデッド原料に添加してもよい。いずれにしてもスプレー等により水を吹き付けることで、原料全体に均等に行き渡るようにするのが好ましい。更に、添加する水分量は、過熱蒸気の温度、チップ及び接着剤の種類、リボンデッド原料の容積、質量等により適宜調整することが好ましい。   Furthermore, the temperature of the superheated steam can be set to 200 ° C. or higher and below the decomposition temperature when the decomposition temperature of the chip that decomposes at the lowest temperature among the chips contained in the chip mixture exceeds 200 ° C. However, when using such high-temperature superheated steam, the amount of water contained in the superheated steam is small, so it is necessary to use a ribbon-dead raw material to which water has been added in advance. This water may be added when the ribbon dead raw material is prepared, that is, a predetermined amount may be added in the step of mixing each component to be blended. Moreover, you may add to the ribbon dead raw material after preparation. In any case, it is preferable that the entire raw material is evenly distributed by spraying water with a spray or the like. Furthermore, it is preferable that the amount of water to be added is appropriately adjusted according to the temperature of the superheated steam, the type of chip and adhesive, the volume and mass of the ribbon dead raw material, and the like.

過熱蒸気の温度は上記のように幅広く設定することができるが、この温度は、成形型の内容積及び過熱蒸気とリボンデッド原料とを接触させる時間等との相関を考慮し、適宜設定することが好ましい。即ち、成形型の内容積が大きい場合は、過熱蒸気の温度が低下する傾向にあるため、より高温の過熱蒸気を使用する及び/又は長時間接触させる等により対処することが好ましい。一方、成形型の内容積が小さい場合は、過熱蒸気が必要以上に高くならず、且つ接触時間も必要以上に長くならないようにして、より効率よく製造することが好ましい。   The temperature of the superheated steam can be set widely as described above, but this temperature should be set appropriately considering the correlation between the inner volume of the mold and the time for contacting the superheated steam with the ribbon dead raw material. Is preferred. That is, when the inner volume of the mold is large, the temperature of the superheated steam tends to decrease. Therefore, it is preferable to use a higher temperature superheated steam and / or contact it for a long time. On the other hand, when the inner volume of the mold is small, it is preferable to manufacture more efficiently so that the superheated steam does not become higher than necessary and the contact time does not become longer than necessary.

過熱蒸気は、生成させた後、温度、圧力を維持したまま貯留することはできない。そのため、成形、脱型等の全工程を通じて供給し続けてもよいが、脱型時にリボンデッド製品を人手で取り出す場合の火傷等の問題がある。一方、脱型時等には過熱蒸気を安全に排気する等の方法もある。しかし、いずれにしても過熱蒸気の有効利用とはならない。この過熱蒸気の有効利用は、過熱蒸気を、成形時にはリボンデッド原料と接触させ、リボンデッド原料の投入時及び脱型時等には過熱蒸気発生器へと循環させ、これらの操作を交互に繰り返す製造方法とすることにより促進することができる。このようにすれば、過熱蒸気が配管内を循環する際の温度低下はあるものの、過熱蒸気をより有効に利用することができる。
尚、このように過熱蒸気発生器へと循環される過熱蒸気は、温度が低下した過熱蒸気であるか、飽和蒸気であることが好ましい。
After the superheated steam is generated, it cannot be stored while maintaining the temperature and pressure. For this reason, the supply may continue throughout all processes such as molding and demolding, but there is a problem such as a burn when the ribbon dead product is manually removed during demolding. On the other hand, there is a method of safely exhausting the superheated steam when demolding. However, in any case, the superheated steam is not effectively used. The effective use of this superheated steam is such that the superheated steam is brought into contact with the ribbon dead raw material at the time of molding, and is circulated to the superheated steam generator when the ribbon dead raw material is charged or demolded, and these operations are repeated alternately. It can promote by setting it as a manufacturing method. In this way, the superheated steam can be used more effectively, although there is a temperature drop when the superheated steam circulates in the pipe.
In addition, it is preferable that the superheated steam circulated to the superheated steam generator in this way is superheated steam with a lowered temperature or saturated steam.

また、過熱蒸気をリボンデッド原料と接触させる操作と、蒸気発生器に供給される水を加熱する供給水加熱手段へと循環させる操作とを交互に繰り返す製造方法とすることにより、過熱蒸気の有効利用を促進することもできる。この方法では、熱水、飽和蒸気又は過熱蒸気を循環させることができるが、過熱蒸気の有効利用の観点からは、循環された過熱蒸気の温度が低下して生成した熱水を循環させることが好ましい。この熱水を、蒸気発生器に水を供給する配管に捲回されたスパイラル管、又は蒸気発生器へと水を供給する配管を内管とする二重管等の供給水加熱手段に循環させ、水温を上昇させることで蒸気発生器においてより少ない熱量で効率よく蒸気を発生させることができる。   In addition, by using a production method that alternately repeats the operation of bringing superheated steam into contact with the ribbon dead raw material and the operation of circulating the water supplied to the steam generator to the feed water heating means, effective superheated steam can be used. Use can also be promoted. In this method, hot water, saturated steam or superheated steam can be circulated, but from the viewpoint of effective use of superheated steam, the temperature of the circulated superheated steam is lowered to circulate hot water generated. preferable. This hot water is circulated to a supply water heating means such as a spiral pipe wound around a pipe for supplying water to the steam generator, or a double pipe having a pipe for supplying water to the steam generator as an inner pipe. By raising the water temperature, steam can be efficiently generated with a smaller amount of heat in the steam generator.

また、過熱蒸気をリボンデッド原料と接触させる操作と、蒸気発生器へと循環させる操作とを交互に繰り返す製造方法とすることにより、過熱蒸気の有効利用を促進することもできる。この方法では、温水、熱水、飽和蒸気又は過熱蒸気を循環させることができるが過熱蒸気の有効利用の観点からは、循環された過熱蒸気の温度が熱水から更に低下して生成した温水を循環させることが好ましい。この温水を、蒸気発生器に水を供給する配管に循環させ、供給される水と混合させることにより水温を上昇させることで、蒸気発生器において少ない熱量で効率よく蒸気を発生させことができる。   Moreover, the effective utilization of superheated steam can also be promoted by adopting a production method in which the operation of bringing the superheated steam into contact with the ribbon dead raw material and the operation of circulating it to the steam generator are alternately repeated. In this method, hot water, hot water, saturated steam or superheated steam can be circulated, but from the viewpoint of effective use of superheated steam, the temperature of the circulated superheated steam is further reduced from the hot water, and the generated hot water is generated. It is preferable to circulate. By circulating this hot water through a pipe for supplying water to the steam generator and mixing it with the supplied water, the water temperature is raised, so that steam can be efficiently generated with a small amount of heat in the steam generator.

リボンデッド製品の製造には、水供給源、水を送出するためのポンプ、水道水の水圧等の送出手段、飽和蒸気を生成させるための蒸気発生器、この飽和蒸気を加熱して過熱蒸気とするための過熱蒸気発生器、及びリボンデッド原料が投入され、この原料と過熱蒸気とが接触して製品が形成される成形型を備え、各々が配管により接続された装置を用いることができる。更に、過熱蒸気は、飽和蒸気発生部と過熱蒸気発生部とを一体に有する装置により生成させることもできる。蒸気発生器、過熱蒸気発生器、成形型、及び飽和蒸気発生部と過熱蒸気発生部とを一体に有する装置は、いずれも一般に提供されているものをそのまま用いることができる。このような装置を用いてリボンデッド製品を製造する場合、過熱蒸気は、成形時にはリボンデッド原料と接触して接着剤を硬化させた後、温水となりドレンとして排出される。また、リボンデッド原料の投入、成形及び脱型が繰り返されるため、過熱蒸気の相当部分は有効利用されないまま廃棄されることになる。尚、この装置には、過熱蒸気の圧力が過度に上昇した場合に備え安全弁等を配設することもできる。
本発明のリボンデッド製品の製造方法では、過熱蒸気の有効利用のため、上記のようにリボンデッド原料の投入及び脱型時に過熱蒸気を過熱蒸気発生器等へと循環させることができ、その場合には以下のような製造装置を使用することができる。
For the production of ribbon dead products, water supply sources, pumps for delivering water , delivery means such as water pressure of tap water , steam generators for generating saturated steam, heating this saturated steam and superheated steam An apparatus in which a superheated steam generator and a ribbon dead raw material are charged, a forming die in which the raw material and the superheated steam come into contact with each other to form a product, and each of which is connected by a pipe can be used. Furthermore, the superheated steam can be generated by an apparatus that integrally includes a saturated steam generating unit and a superheated steam generating unit. As the steam generator, the superheated steam generator, the molding die, and the apparatus that integrally includes the saturated steam generating unit and the superheated steam generating unit, those generally provided can be used as they are. When a ribbon dead product is manufactured using such an apparatus, the superheated steam is brought into contact with the ribbon dead raw material at the time of molding to cure the adhesive, and then becomes hot water and discharged as drain. In addition, since the ribbon dead raw material is repeatedly charged, molded, and demolded, a substantial portion of the superheated steam is discarded without being effectively used. In addition, in this apparatus, a safety valve etc. can also be arrange | positioned in case the pressure of superheated steam rises too much.
In the ribbon dead product manufacturing method of the present invention, for the effective use of superheated steam, it is possible to circulate superheated steam to a superheated steam generator or the like at the time of charging and demolding of the ribbon dead raw material as described above. The following manufacturing apparatus can be used.

リボンデッド原料の投入循環及び脱型時等に過熱蒸気を過熱蒸気発生器へと循環させる場合は、図1のように、成形型4、一端側が成形型に接続された過熱蒸気供給用配管64、過熱蒸気供給用配管64の他端側に接続された過熱蒸気流路切替手段71、一端側が過熱蒸気流路切替手段71に接続された過熱蒸気移送用配管63、過熱蒸気移送用配管63の他端側に接続された過熱蒸気発生器3、一端側が過熱蒸気発生器3に接続された蒸気移送用配管62、蒸気移送用配管62の他端側に接続された蒸気発生器2、一端側が蒸気発生器2に接続された水供給用配管61、水供給用配管61の他端側に接続された水供給源1、及び一端側が過熱蒸気流路切替手段71に接続され且つ他端側が蒸気移送用配管62に接続された循環用配管65、を備える製造装置を用いることができる。   When the superheated steam is circulated to the superheated steam generator when the ribbon dead raw material is charged and demolded, as shown in FIG. 1, the superheated steam supply pipe 64 having one end connected to the mold 4 as shown in FIG. The superheated steam channel switching means 71 connected to the other end side of the superheated steam supply pipe 64, the superheated steam transfer pipe 63 connected at one end side to the superheated steam channel switching means 71, and the superheated steam transfer pipe 63 The superheated steam generator 3 connected to the other end side, the steam transfer pipe 62 connected to the superheated steam generator 3 at one end side, the steam generator 2 connected to the other end side of the steam transfer pipe 62, and one end side A water supply pipe 61 connected to the steam generator 2, a water supply source 1 connected to the other end of the water supply pipe 61, and one end connected to the superheated steam flow path switching means 71 and the other end connected to steam A circulation pipe 65 connected to the transfer pipe 62; The manufacturing apparatus can be used with.

水供給源としては所定容量のタンク等を用いることができる。また、ポンプとしては各種の定流量ポンプ等を使用することができる。更に、蒸気発生器としては水を飽和蒸気にすることができる通常の装置を使用することができる。また、過熱蒸気発生器も飽和蒸気を加熱し、過熱蒸気とすることができる一般的な装置を用いることができる。更に、過熱蒸気流路切替手段は特に限定されず、例えば、3方向流路切替弁等を使用することができる。そして、成形時には過熱蒸気の流路を過熱蒸気供給用配管へと切り替え、リボンデッド原料の投入時及び脱型時等には過熱蒸気の流路を循環用配管へと切り替えることで、過熱蒸気をより有効に利用することができる。この循環用配管は蒸気供給用配管に接続されており、循環された過熱蒸気は蒸気発生器から送出される飽和蒸気と混合され、過熱蒸気発生器に供給される。従って、循環された過熱蒸気は、蒸気供給用配管に導入される時点で過熱蒸気又は少なくとも飽和蒸気であることが好ましい。   As a water supply source, a tank having a predetermined capacity can be used. Moreover, various constant flow pumps etc. can be used as a pump. Further, as the steam generator, an ordinary apparatus capable of making water into saturated steam can be used. Moreover, the superheated steam generator can also use the general apparatus which heats saturated steam and can be used as superheated steam. Further, the superheated steam channel switching means is not particularly limited, and for example, a three-way channel switching valve or the like can be used. Then, the superheated steam channel is switched to the superheated steam supply pipe at the time of molding, and the superheated steam channel is switched to the circulation pipe when the ribbon dead raw material is charged and demolded. It can be used more effectively. This circulation pipe is connected to a steam supply pipe, and the circulated superheated steam is mixed with saturated steam sent from the steam generator and supplied to the superheated steam generator. Therefore, the circulated superheated steam is preferably superheated steam or at least saturated steam when introduced into the steam supply pipe.

また、過熱蒸気を供給水加熱手段に循環させる場合は、図2のように、水供給用配管61に付設された供給水加熱手段5、及び一端側が過熱蒸気流路切替手段71に接続され且つ他端側が供給水加熱手段5に接続された循環用配管65a、を備え、その他は上記と同様の製造装置を用いることができる。供給水加熱手段は特に限定されないが、例えば、水供給用配管の外周に捲回された螺旋管が挙げられる。更に、水供給用配管を内管とし、この内管と、その外周に配設された外管とからなる二重管が挙げられる。この螺旋管内又は二重管の内外管の間の流路を、循環された過熱蒸気が降温してなる熱水等を流通させることで、供給水が加熱されて昇温し、この昇温した水を蒸気発生器に供給することができる。このようにして過熱蒸気を有効に利用することができる。この場合、循環された過熱蒸気は、供給水加熱手段に導入される時点で熱水又は熱水を含む蒸気であることが好ましく、熱水又は熱水を含む蒸気であれば、供給水を十分に昇温させることができる。尚、供給水加熱手段に過熱蒸気又は飽和蒸気を循環させることもでき、特に過熱蒸気を循環させた場合は、供給水加熱手段により飽和蒸気を生成させることもでき、この場合は蒸気発生器がなくてもよい。但し、過熱蒸気の有効利用の観点からは、過熱蒸気又は飽和蒸気は、上記のように過熱蒸気発生器へと循環させることが好ましい。   When circulating the superheated steam to the feed water heating means, as shown in FIG. 2, the feed water heating means 5 attached to the water supply pipe 61 and one end side are connected to the superheat steam flow switching means 71 and The other end side includes a circulation pipe 65 a connected to the feed water heating means 5, and the other manufacturing apparatus similar to the above can be used. The supply water heating means is not particularly limited, and examples thereof include a spiral tube wound around the outer periphery of the water supply pipe. Furthermore, the water supply pipe is an inner pipe, and a double pipe comprising this inner pipe and an outer pipe disposed on the outer periphery thereof can be mentioned. By flowing hot water or the like in which the circulating superheated steam is cooled through the flow path between the inner and outer pipes of the spiral pipe or the double pipe, the supply water is heated to raise the temperature. Water can be supplied to the steam generator. In this way, the superheated steam can be used effectively. In this case, it is preferable that the circulated superheated steam is hot water or steam containing hot water when introduced into the feed water heating means. If the steam contains hot water or hot water, supply water is sufficient. The temperature can be increased. In addition, superheated steam or saturated steam can be circulated in the feed water heating means, and in particular, when superheated steam is circulated, saturated steam can be generated by the feed water heating means. It does not have to be. However, from the viewpoint of effective use of superheated steam, it is preferable to circulate superheated steam or saturated steam to the superheated steam generator as described above.

更に、過熱蒸気を水供給用配管に循環させる場合は、図3のように、一端側が過熱蒸気流路切替手段71に接続され且つ他端側が水供給用配管61に接続された循環用配管65b、を備え、その他は上記と同様の製造装置を用いることができる。この場合、循環された過熱蒸気は、水供給用配管に導入される時点で供給水より高温の温水であることが好ましく、この温水は供給水と混合され、より高温となった水が蒸気発生器に供給される。このようにして過熱蒸気を有効に利用することができる。尚、循環された過熱蒸気が供給水と混合される時点で熱水又は熱水を含む蒸気であってもよい。但し、過熱蒸気の有効利用の観点からは、熱水又は熱水を含む蒸気は、上記のように供給水加熱手段へと循環させることが好ましい。   Further, when circulating the superheated steam to the water supply pipe, as shown in FIG. 3, a circulation pipe 65b in which one end side is connected to the superheated steam flow switching means 71 and the other end side is connected to the water supply pipe 61. In other respects, the same manufacturing apparatus as described above can be used. In this case, it is preferable that the circulated superheated steam is hot water having a temperature higher than that of the supply water when it is introduced into the water supply pipe, and this hot water is mixed with the supply water, so that the water having a higher temperature generates steam. Supplied to the vessel. In this way, the superheated steam can be used effectively. The circulating superheated steam may be hot water or steam containing hot water at the time when it is mixed with the supply water. However, from the viewpoint of effective use of superheated steam, it is preferable to circulate hot water or steam containing hot water to the feed water heating means as described above.

以上、詳述した製造装置により過熱蒸気を有効利用することができるが、本発明の装置では、図4のように、循環用配管65の流路を更に3方向流路切替弁等の流路切替手段72により分岐させ、蒸気移送用配管62に接続される循環用配管651と、供給水加熱手段5に接続される循環用配管652とを備える。また、配管652は、供給水加熱手段5ではなく水供給用配管61に接続させることもできる。このような装置にすれば、循環された過熱蒸気を蒸気供給用配管に循環させるべきか、供給水過熱手段又は水供給用配管に循環させるべきか、によって適宜流路を切り替えることができ、過熱蒸気の有効利用をより促進することができる。 As described above, the superheated steam can be effectively used by the manufacturing apparatus described in detail. However, in the apparatus of the present invention, as shown in FIG. A circulation pipe 651 branched by the switching means 72 and connected to the steam transfer pipe 62 and a circulation pipe 652 connected to the feed water heating means 5 are provided. Further, the pipe 652 can be connected to the water supply pipe 61 instead of the supply water heating means 5. With such a device, the flow path can be switched appropriately depending on whether the circulated superheated steam should be circulated to the steam supply pipe or to the supply water superheating means or the water supply pipe. The effective use of steam can be further promoted.

また、この装置では、図5のように、循環用配管65から供給水過熱手段5又は水供給用配管61へと分岐された配管652に更に3方向流路切替弁等の流路切替手段73が配設され、供給水加熱手段5に接続される配管6521と、水供給用配管61に接続される配管6522とに流路が分岐された装置とすることもできる。このような装置にすれば、循環された過熱蒸気を供給水加熱手段に循環させるべきか、水供給用配管に循環させるべきか、によって適宜流路を切り替えることができる。
更に、リボンデッド製品の製造では、成形型から排出される温水は、通常、ドレンとして廃棄されるが、図6のように、この温水を排出温水循環用配管66により水供給用配管61に循環させることができ、これによって蒸気発生器2に供給される水温を高くすることもできる。
Further, in this apparatus, as shown in FIG. 5, a flow path switching means 73 such as a three-way flow path switching valve is further added to the pipe 652 branched from the circulation pipe 65 to the supply water superheating means 5 or the water supply pipe 61. And a device in which the flow path is branched into a pipe 6521 connected to the supply water heating means 5 and a pipe 6522 connected to the water supply pipe 61. According to such an apparatus, the flow path can be appropriately switched depending on whether the circulated superheated steam should be circulated to the supply water heating means or the water supply piping.
Further, in the manufacture of ribbon dead products, the hot water discharged from the mold is usually discarded as drain, but this hot water is circulated to the water supply pipe 61 through the discharge hot water circulation pipe 66 as shown in FIG. Accordingly, the temperature of the water supplied to the steam generator 2 can be increased.

以下、実施例により本発明を具体的に説明する。
実験例1

A ribbon dead product was obtained in the same manner as in Experimental Example 1 except that superheated steam obtained by superheating saturated steam at a pressure of 0.01 MPa to 175 ° C. and supplying this superheated steam for 30 seconds.
Experimental Example 4
A ribbon dead product was obtained in the same manner as in Experimental Example 3 except that the temperature of the superheated steam was 200 ° C.
Experimental Example 5

Experimental Example 6
Preparation of the ribbon dead raw material in Experimental Example 1 was performed while spraying the adhesive and spraying 20 g of water.

The results of visual observation of the manufacturing conditions of the ribbon dead products of Experimental Examples 1 to 7 and the appearance of the obtained ribbon dead products are shown in Table 1.
In Table 1, the evaluation criteria for the appearance are: ◎: There is no defect such as chipping off and has an excellent appearance, ○: There is no particular defect, but a little compared with the case of ◎ Inferior, Δ: There are portions where the adhesive is not sufficiently cured, and the appearance is slightly inferior.

表1の結果によれば、供給された過熱蒸気の温度が118〜175℃の実験例1〜3では、チップの脱落等の欠陥がなく、優れた外観を有していることが分かる。特に、過熱蒸気の温度が175℃の実験例3では、過熱蒸気の供給時間が30秒と短時間であるにもかかわらず、優れた外観の製品が得られた。また、過熱蒸気の温度が200℃と高く、その供給時間が30秒と短時間である実験例4では、水分が不十分であり、接着剤が十分に硬化していない部分があり、やや外観が劣っていた。更に、実験例4と同程度の温度の過熱蒸気を使用し、供給時間を60秒と長くした実験例5では、実験例4の製品に比べて品質向上がみられたが、実験例1〜3の製品に比べると外観がやや劣っていた。また、過熱蒸気の温度が190℃であり、リボンデッド原料に予め所定量の水を添加した実験例6では、過熱蒸気の供給時間が短時間であるにもかかわらず、チップの脱落等の欠陥がなく、優れた外観を有しており、リボンデッド原料に予め水を添加しておくことが有用であることが実証された。更に、過熱蒸気の温度が255℃と高い実験例7では、リボンデッド原料に予め所定量の水を添加したにもかかわらず、実験例5と同様に実験例1〜3の製品に比べると外観がやや劣っていた。この結果より、リボンデッド原料に予め水を添加しておいても、過熱蒸気の温度が過度に高い場合は水の不足により接着剤が十分に硬化し得ない場合があることが分かる。
尚、実験例1〜7のすべてにおいて、乾燥させなかったにもかかわらず、製品表面はまったく濡れていなかった。
According to the results of Table 1, it can be seen that in Experimental Examples 1 to 3 in which the temperature of the supplied superheated steam is 118 to 175 ° C., there is no defect such as chipping off, and it has an excellent appearance. In particular, in Experimental Example 3 in which the temperature of the superheated steam was 175 ° C., a product having an excellent appearance was obtained even though the superheated steam was supplied for a short time of 30 seconds. Further, in Experimental Example 4 where the temperature of the superheated steam is as high as 200 ° C. and the supply time is as short as 30 seconds, there is a portion where the moisture is insufficient and the adhesive is not sufficiently cured, and the appearance is somewhat Was inferior. Furthermore, in Experimental Example 5 in which superheated steam having a temperature similar to that of Experimental Example 4 was used and the supply time was increased to 60 seconds, the quality was improved as compared with the product of Experimental Example 4. The appearance was slightly inferior to the product of 3. Further, in Experimental Example 6 in which the temperature of the superheated steam was 190 ° C. and a predetermined amount of water was added to the ribbon dead raw material in advance, defects such as chip dropping were observed even though the superheated steam was supplied for a short time. It was proved that it was useful to add water to the ribbon dead raw material in advance. Further, in Experimental Example 7 where the temperature of the superheated steam is as high as 255 ° C., the appearance is compared with the products of Experimental Examples 1 to 3 as in Experimental Example 5 even though a predetermined amount of water was previously added to the ribbon dead raw material. It was somewhat inferior. From this result, it can be seen that even if water is added to the ribbon dead raw material in advance, if the temperature of the superheated steam is excessively high, the adhesive may not be sufficiently cured due to lack of water.
In all of Experimental Examples 1 to 7, although the product was not dried, the product surface was not wet at all.
