Description

筒状体cylindrical body
　本発明は、筒状体に関する。 The present invention relates to a cylindrical body.
　従来、第１および第２の材料条片部分から製造される２層状の小管体（筒状体）が知られている（例えば、特許文献１参照）。この２層状の小管体は、例えば材料の燃焼をすることなく香味等を吸引するための非燃焼型香味吸引器で使用される香味発生物品や、燃焼型の喫煙物品に適用され得る。 Conventionally, a two-layered small tube body (cylindrical body) manufactured from first and second material strip portions is known (for example, see Patent Document 1). This two-layered small tube body can be applied, for example, to a flavor-generating article used in a non-combustible flavor inhaler for inhaling flavor without burning the material, or to a combustion-type smoking article.
　この小管体において、第２の材料条片部分が第１の材料条片部分の周囲に配置されており、第１および第２の材料条片部分の当接縁部が円周方向において相互に位置ずれするように巻回されている。また、この小管体において、第１の材料条片部分と第２の材料条片部分との間に、位置決め粘着剤および継ぎ目粘着剤（これらを合わせて接着剤と称する）が、全面に、または、ほぼ全面に設けられている。 In this tubular body, the second material strip portion is arranged around the first material strip portion, and the abutting edges of the first and second material strip portions are circumferentially mutually disposed. It is wound so that the position is shifted. Further, in this small tube body, a positioning adhesive and a seam adhesive (together referred to as adhesive) are applied between the first material strip portion and the second material strip portion on the entire surface or , located almost on the entire surface.
特開２０１８－９３８６７号公報JP2018-93867A
　特許文献１に記載の小管体を香味発生物品や喫煙物品に適用する場合、小管体は、香味発生物品や喫煙物品の半製品に組み込まれた後、小管体の外周から内周に向けてレーザ光線が照射され、照射箇所の材料を燃焼させることで、周方向の全周にわたって断続的に、小管体を貫く通気孔が形成され得る。 When applying the small tube described in Patent Document 1 to a flavor-producing article or a smoking article, the small tube is incorporated into a semi-finished product of the flavor-generating article or smoking article, and then laser is applied from the outer circumference of the small tube toward the inner circumference. By irradiating the light beam and burning the material at the irradiated location, vent holes can be formed that penetrate the small tube body intermittently over the entire circumference in the circumferential direction.
　ここで、特許文献１に記載の小管体では、接着剤が、第１の材料条片部分と第２の材料条片部分との間に、全面に、または、ほぼ全面に設けられている。そのため、通気孔を形成する際、接着剤の燃焼灰が通気孔を閉塞するおそれがある。 Here, in the small tube body described in Patent Document 1, the adhesive is provided on the entire surface or almost the entire surface between the first material strip portion and the second material strip portion. Therefore, when forming the ventilation holes, there is a risk that the combustion ash of the adhesive may clog the ventilation holes.
　具体的には、小管体を構成する紙は、例えば、有機物である木質パルプ（樹木が含むリグニン・ヘミセルロース等が除去されたほぼ純粋なセルロース）および無機物である填料（炭酸カルシウム）であり、レーザ光線を照射することによって生じる燃焼灰は、炭酸カルシウムが主体である。 Specifically, the paper that makes up the tubules is made of, for example, organic wood pulp (nearly pure cellulose from which lignin, hemicellulose, etc. contained in trees have been removed) and an inorganic filler (calcium carbonate). The combustion ash produced by irradiation with light is mainly composed of calcium carbonate.
　これに対して、接着剤は、例えば、有機高分子である改質でんぷん、酢酸ビニルまたはエチレン酢酸ビニルとアルコール類と水との混錬物であり、レーザ光線を照射することによって生じる燃焼灰には、燃焼残の有機高分子が混ざる。 On the other hand, adhesives are, for example, mixtures of organic polymers such as modified starch, vinyl acetate, or ethylene vinyl acetate, alcohols, and water, and are made of a mixture of organic polymers such as modified starch, vinyl acetate, or ethylene vinyl acetate, alcohols, and water. is mixed with organic polymers left over from combustion.
　そのため、接着剤が塗布された箇所に形成された通気孔における燃焼灰は、炭酸カルシウムと有機高分子とが混ざったものとなり、接着剤が塗布されていない箇所に形成された通気孔における炭酸カルシウム主体の燃焼灰よりも、粘着性があり通気孔を閉塞しやすい。 Therefore, the combustion ash in vents formed in areas where adhesive has been applied is a mixture of calcium carbonate and organic polymers, and the combustion ash in vents formed in areas where adhesive has not been applied is a mixture of calcium carbonate and organic polymers. It is more sticky than the main combustion ash and tends to clog vents.
　通気孔が閉塞された小管体が香味発生物品や喫煙物品に適用されると、通気孔から香味発生物品や喫煙物品の内部に空気が導入されないので、香味発生物品の加熱や喫煙物品の燃焼によって発生したエアロゾルが冷却されず、また、エアロゾル濃度が低減されない。そのため、香味発生物品や喫煙物品の品質が低下するおそれがある。 When a small tube with a closed ventilation hole is applied to a flavor-generating article or a smoking article, air is not introduced into the flavor-generating article or smoking article through the ventilation hole, so the heating of the flavor-generating article or the combustion of the smoking article prevents air from entering the flavor-generating article or smoking article. The generated aerosol is not cooled and the aerosol concentration is not reduced. Therefore, the quality of flavor-producing articles and smoking articles may deteriorate.
　本発明は、上記のような課題の少なくとも一部を解決するためになされたものであり、通気孔が形成される場合に、接着剤の燃焼灰が通気孔を閉塞することを抑制することができる筒状体を得ることを目的とする。 The present invention has been made to solve at least a part of the above-mentioned problems, and it is possible to prevent the combustion ash of the adhesive from clogging the vent when the vent is formed.

The filling layer 310 can be, for example, a rod filled with cellulose acetate fibers at high density and hardened by adding a plasticizer containing triacetin.
　中空部の直径は、特に限定されないが、例えば１．０ｍｍ～５．０ｍｍであってもよい。充填層３１０は、繊維の充填密度が高いため、吸引時は空気やエアロゾルが中空部のみを流れることになり、充填層３１０内をほとんど流れない。充填層３１０が中空部を有することにより、香味発生物品１０の加熱によって発生した香味成分を含むエアロゾルが濾過される量を低減することができる。 The diameter of the hollow portion is not particularly limited, but may be, for example, 1.0 mm to 5.0 mm. Since the packed bed 310 has a high packing density of fibers, air and aerosol flow only through the hollow portion during suction, and hardly flow inside the packed bed 310. Since the filling layer 310 has a hollow portion, it is possible to reduce the amount of aerosol containing flavor components generated by heating the flavor-generating article 10 that is filtered.
　フィルタセグメント１５は、濾材３３０と、濾材３３０を包む筒状の第２インナープラグラッパー３４０とを有する。濾材３３０は、多孔質材料が充填された中実プラグであってもよい。フィルタセグメント１５が中実プラグを有することにより、香味発生物品１０の加熱によって発生した香味成分を含むエアロゾルを濾過して、エアロゾルのデリバリー量を適切に調整することができる。 The filter segment 15 includes a filter medium 330 and a cylindrical second inner plug wrapper 340 that surrounds the filter medium 330. Filter media 330 may be a solid plug filled with porous material. Since the filter segment 15 has a solid plug, it is possible to filter the aerosol containing flavor components generated by heating the flavor-generating article 10 and appropriately adjust the amount of aerosol delivered.
　センターホールセグメント１４とフィルタセグメント１５とは、アウタープラグラッパー３５０で互いに接続される。アウタープラグラッパー３５０は、例えば円筒状の紙であってもよい。また、たばこ含有セグメント１１と、冷却セグメント１３と、接続済みのセンターホールセグメント１４およびフィルタセグメント１５とは、内側面に酢酸ビニル系糊等の糊が塗布されたマウスピースライニングペーパー４００が巻装されることによって互いに接続される。 The center hole segment 14 and the filter segment 15 are connected to each other by an outer plug wrapper 350. The outer plug wrapper 350 may be, for example, cylindrical paper. Furthermore, the tobacco-containing segment 11, the cooling segment 13, the connected center hole segment 14, and the filter segment 15 are wrapped with mouthpiece lining paper 400 coated with a glue such as vinyl acetate glue on the inner surface. are connected to each other by

The second sheet-like material 120 is provided around the outer periphery of the first sheet-like material 110. The adhesive layer 130 is provided between the first sheet material 110 and the second sheet material 120, and adheres the first sheet material 110 and the second sheet material 120 to each other.
　第１シート状材料１１０および第２シート状材料１２０は、それぞれ紙または厚紙で構成され得る。そのため、筒状体１００の加工性を向上させることができる。なお、第１シート状材料１１０および第２シート状材料１２０は、軸方向に直交する断面形状が楕円形であってもよい。 The first sheet material 110 and the second sheet material 120 may each be composed of paper or cardboard. Therefore, the workability of the cylindrical body 100 can be improved. Note that the first sheet-like material 110 and the second sheet-like material 120 may have an elliptical cross-sectional shape perpendicular to the axial direction.

The first sheet material 110 has a first body portion 111 and a first extension portion 112 that extends from the first body portion 111 in the circumferential direction with respect to the opposing second sheet material 120 . The first main body portion 111 is a portion facing the second sheet material 120 in FIG. 4 .
　第２シート状材料１２０は、第２本体部１２１と、対向する第１シート状材料１１０に対して周方向に第２本体部１２１から延出する第２延出部１２２とを有する。第２本体部１２１は、図４において、第１シート状材料１１０と対向する部分である。 The second sheet material 120 has a second main body portion 121 and a second extending portion 122 that extends from the second main body portion 121 in the circumferential direction with respect to the opposing first sheet material 110. The second main body portion 121 is a portion facing the first sheet-like material 110 in FIG.

It has a second seam adhesive layer 133 (seam adhesive layer) to be adhered. Note that the first seam adhesive layer 132 does not necessarily need to be provided, and the positioning adhesive layer 131 may function as the first seam adhesive layer 132.
　位置決め接着層１３１、第１継目接着層１３２および第２継目接着層１３３は、有機高分子である改質でんぷん、酢酸ビニルまたはエチレン酢酸ビニルとアルコール類と水との混錬物で構成され得る。なお、位置決め接着層１３１、第１継目接着層１３２および第２継目接着層１３３は、上記のものに限定されず、他の接着剤で構成されてもよい。 The positioning adhesive layer 131, the first seam adhesive layer 132, and the second seam adhesive layer 133 may be composed of a mixture of organic polymers such as modified starch, vinyl acetate, or ethylene vinyl acetate, alcohol, and water. Note that the positioning adhesive layer 131, the first seam adhesive layer 132, and the second seam adhesive layer 133 are not limited to those described above, and may be made of other adhesives.
　筒状体１００は、第２シート状材料１２０上に位置決め接着層１３１、第１継目接着層１３２および第２継目接着層１３３が塗布され、第１シート状材料１１０が重ねられた後、筒状に成形されて構成される。ここで、第２シート状材料１２０に塗布される位置決め接着層１３１は、線状に位置決め糊（接着剤）が塗布された接着パターンを有する。なお、第２シート状材料１２０に代えて、第１シート状材料１１０に位置決め接着層１３１、第１継目接着層１３２および第２継目接着層１３３が塗布されてもよい。 The cylindrical body 100 is formed by coating a positioning adhesive layer 131, a first seam adhesive layer 132, and a second seam adhesive layer 133 on the second sheet-like material 120, and stacking the first sheet-like material 110 on top of the second sheet-like material 120. It is formed and configured. Here, the positioning adhesive layer 131 applied to the second sheet material 120 has an adhesive pattern in which positioning glue (adhesive) is applied in a linear manner. Note that instead of the second sheet material 120, a positioning adhesive layer 131, a first seam adhesive layer 132, and a second seam adhesive layer 133 may be applied to the first sheet material 110.
　通気孔１４０は、第１シート状材料１１０および第２シート状材料１２０を貫通して、筒状体１００の周方向に複数形成されている。ここで、第２シート状材料１２０に塗布される位置決め接着層１３１が、線状に位置決め糊（接着剤）が塗布された接着パターンを有することから、複数の通気孔１４０は、接着層１３０が通気孔１４０の孔内面に露出する第１通気孔１４１と、接着層１３０が通気孔１４０の孔内面に露出しない第２通気孔１４２と、を有する。 A plurality of ventilation holes 140 are formed in the circumferential direction of the cylindrical body 100, passing through the first sheet material 110 and the second sheet material 120. Here, since the positioning adhesive layer 131 applied to the second sheet-like material 120 has an adhesive pattern in which positioning glue (adhesive) is applied in a linear manner, the plurality of ventilation holes 140 are formed in the adhesive layer 130. The vent hole 140 has a first vent hole 141 exposed to the inner surface of the vent hole 140 and a second vent hole 142 in which the adhesive layer 130 is not exposed to the inner surface of the vent hole 140 .
　具体的には、第１通気孔１４１は、位置決め接着層１３１、第１継目接着層１３２および第２継目接着層１３３の何れかとともに、第１シート状材料１１０および第２シート状材料１２０を貫通して形成される。また、第２通気孔１４２は、位置決め接着層１３１、第１継目接着層１３２および第２継目接着層１３３の何れも設けられていない箇所で、第１シート状材料１１０および第２シート状材料１２０を貫通して形成される。 Specifically, the first ventilation hole 141 penetrates the first sheet material 110 and the second sheet material 120 together with any one of the positioning adhesive layer 131, the first seam adhesive layer 132, and the second seam adhesive layer 133. It is formed by Further, the second ventilation hole 142 is located at a location where none of the positioning adhesive layer 131, the first seam adhesive layer 132, and the second seam adhesive layer 133 are provided, It is formed by penetrating the
　このように、複数の通気孔１４０が、接着層１３０が通気孔１４０の孔内面に露出する少なくとも１つの第１通気孔１４１と、接着層１３０が通気孔１４０の孔内面に露出しない少なくとも１つの第２通気孔１４２と、を有することにより、接着層１３０が設けられた箇所に通気孔１４０が形成される確率を低減して、接着剤の燃焼灰が通気孔１４０を閉塞することを抑制することができる。その結果、筒状体１００が適用された香味発生物品１０の品質の低下を抑制することができる。 In this way, the plurality of vent holes 140 include at least one first vent hole 141 in which the adhesive layer 130 is exposed to the inner surface of the vent hole 140 and at least one first vent hole 141 in which the adhesive layer 130 is not exposed to the inner surface of the vent hole 140. By having the second vent hole 142, the probability that the vent hole 140 is formed at the location where the adhesive layer 130 is provided is reduced, and the combustion ash of the adhesive is prevented from clogging the vent hole 140. be able to. As a result, deterioration in quality of the flavor-producing article 10 to which the cylindrical body 100 is applied can be suppressed.
　図５は、本発明の一実施形態に係る筒状体の第２シート状材料を示す展開図である。図５に示すように、第２シート状材料１２０は、軸方向に平行な直線状に、２本の位置決め糊が塗布された位置決め接着層１３１を有する。 FIG. 5 is a developed view showing the second sheet-like material of the cylindrical body according to an embodiment of the present invention. As shown in FIG. 5, the second sheet material 120 has a positioning adhesive layer 131 coated with two positioning glues in a straight line parallel to the axial direction.
　このように、位置決め接着層１３１が、軸方向に平行な直線状に、２本の位置決め糊が塗布された接着パターンを有することにより、位置決め接着層を全面に設ける場合と比較して、接着剤の塗布量を削減することができる。また、接着層１３０が設けられた箇所に通気孔１４０が形成される確率を低減して、接着剤の燃焼灰が通気孔１４０を閉塞することを抑制することができる。 In this way, since the positioning adhesive layer 131 has an adhesive pattern in which two positioning adhesives are applied in a straight line parallel to the axial direction, the adhesive The amount of coating can be reduced. Furthermore, it is possible to reduce the probability that the vent hole 140 will be formed at a location where the adhesive layer 130 is provided, and to prevent the combustion ash of the adhesive from clogging the vent hole 140.
　なお、位置決め接着層１３１の接着パターンは、図５に示したものに限定されない。図６は、本発明の一実施形態に係る筒状体の第２シート状材料を示す別の展開図である。図６に示すように、第２シート状材料１２０は、軸方向に沿ってらせん状に位置決め糊が塗布された位置決め接着層１３１を有する。 Note that the adhesive pattern of the positioning adhesive layer 131 is not limited to that shown in FIG. 5. FIG. 6 is another developed view showing the second sheet-like material of the cylindrical body according to one embodiment of the present invention. As shown in FIG. 6, the second sheet-like material 120 has a positioning adhesive layer 131 on which positioning glue is applied spirally along the axial direction.
　このように、位置決め接着層１３１が、軸方向に沿ってらせん状に位置決め糊が塗布された接着パターンを有することにより、位置決め接着層を全面に設ける場合と比較して、接着剤の塗布量を削減することができる。また、接着層１３０が設けられた箇所に通気孔１４０が形成される確率を低減して、接着剤の燃焼灰が通気孔１４０を閉塞することを抑制することができる。 As described above, since the positioning adhesive layer 131 has an adhesive pattern in which the positioning adhesive is applied spirally along the axial direction, the amount of adhesive applied can be reduced compared to the case where the positioning adhesive layer is provided on the entire surface. can be reduced. Furthermore, it is possible to reduce the probability that the vent hole 140 will be formed at a location where the adhesive layer 130 is provided, and to prevent the combustion ash of the adhesive from clogging the vent hole 140.
　図７は、本発明の一実施形態に係る筒状体の第２シート状材料を示す別の展開図である。図７に示すように、第２シート状材料１２０は、軸方向に平行な直線状に、３本の位置決め糊が塗布された位置決め接着層１３１を有する。 FIG. 7 is another developed view showing the second sheet material of the cylindrical body according to an embodiment of the present invention. As shown in FIG. 7, the second sheet material 120 has a positioning adhesive layer 131 coated with three positioning glues in a straight line parallel to the axial direction.
　このように、位置決め接着層１３１が、軸方向に平行な直線状に、３本の位置決め糊が塗布された接着パターンを有することにより、位置決め接着層を全面に設ける場合と比較して、接着剤の塗布量を削減することができる。また、接着層１３０が設けられた箇所に通気孔１４０が形成される確率を低減して、接着剤の燃焼灰が通気孔１４０を閉塞することを抑制することができる。 In this way, since the positioning adhesive layer 131 has an adhesive pattern in which three positioning adhesives are applied in a straight line parallel to the axial direction, the adhesive The amount of coating can be reduced. Furthermore, it is possible to reduce the probability that the vent hole 140 will be formed at a location where the adhesive layer 130 is provided, and to prevent the combustion ash of the adhesive from clogging the vent hole 140.
　図８は、本発明の一実施形態に係る筒状体の第２シート状材料を示す別の展開図である。図８に示すように、第２シート状材料１２０は、軸方向に対して直交する直線状に、３本の位置決め糊が塗布された位置決め接着層１３１を有する。なお、位置決め糊は、２本塗布されてもよいし、４本以上塗布されてもよい。 FIG. 8 is another developed view showing the second sheet material of the cylindrical body according to an embodiment of the present invention. As shown in FIG. 8, the second sheet material 120 has a positioning adhesive layer 131 coated with three positioning glues in a straight line perpendicular to the axial direction. Note that two or more positioning glues may be applied.
　このように、位置決め接着層１３１が、軸方向に対して直交する直線状に、３本の位置決め糊が塗布された接着パターンを有することにより、位置決め接着層を全面に設ける場合と比較して、接着剤の塗布量を削減することができる。また、接着層１３０が設けられた箇所に通気孔１４０が形成される確率を低減して、接着剤の燃焼灰が通気孔１４０を閉塞することを抑制することができる。 In this way, since the positioning adhesive layer 131 has an adhesive pattern in which three positioning glues are applied in a straight line perpendicular to the axial direction, compared to the case where the positioning adhesive layer is provided on the entire surface, The amount of adhesive applied can be reduced. Furthermore, it is possible to reduce the probability that the vent hole 140 will be formed at a location where the adhesive layer 130 is provided, and to prevent the combustion ash of the adhesive from clogging the vent hole 140.
　ここで、複数の通気孔１４０における通気孔１４０の数は、１２以上３０以下であることが好ましく、２１以下であることがより好ましい。複数の通気孔１４０における通気孔１４０の数を１２以上３０以下、より好ましくは２１以下とすることにより、充分な空気を内部に導入しつつ、接着層１３０が設けられた箇所に通気孔１４０が形成される確率を低減して、接着剤の燃焼灰が通気孔１４０を閉塞することを抑制することができる。 Here, the number of ventilation holes 140 in the plurality of ventilation holes 140 is preferably 12 or more and 30 or less, and more preferably 21 or less. By setting the number of ventilation holes 140 in the plurality of ventilation holes 140 to 12 or more and 30 or less, more preferably 21 or less, the ventilation holes 140 can be formed at the location where the adhesive layer 130 is provided while introducing sufficient air into the interior. By reducing the probability of formation, it is possible to prevent adhesive combustion ash from clogging the vent hole 140.
　また、第１通気孔１４１の数は、６以下であることが好ましい。第１通気孔１４１の数を６以下とすることにより、充分な空気を内部に導入しつつ、接着層１３０が設けられた箇所に通気孔１４０が形成される確率を低減して、接着剤の燃焼灰が通気孔１４０を閉塞することを抑制することができる。 Furthermore, the number of first ventilation holes 141 is preferably six or less. By setting the number of first ventilation holes 141 to six or less, sufficient air can be introduced into the interior, while reducing the probability that the ventilation holes 140 will be formed at the location where the adhesive layer 130 is provided. It is possible to prevent combustion ash from clogging the ventilation holes 140.
　また、複数の通気孔１４０の総数に対する、第１通気孔１４１の数の割合は、１／４未満であるであることが好ましい。複数の通気孔１４０の総数に対する、第１通気孔１４１の数の割合を１／４未満とすることにより、充分な空気を内部に導入しつつ、接着層１３０が設けられた箇所に通気孔１４０が形成される確率を低減して、接着剤の燃焼灰が通気孔１４０を閉塞することを抑制することができる。 Furthermore, the ratio of the number of first ventilation holes 141 to the total number of the plurality of ventilation holes 140 is preferably less than 1/4. By setting the ratio of the number of the first ventilation holes 141 to the total number of the plurality of ventilation holes 140 to be less than 1/4, sufficient air can be introduced into the interior, and the ventilation holes 141 can be formed at the location where the adhesive layer 130 is provided. It is possible to reduce the probability that ash will be formed and to prevent the adhesive combustion ash from clogging the vent hole 140.
　なお、複数の通気孔１４０は、軸方向に沿って２列以上形成されてもよい。複数の通気孔１４０を、軸方向に沿って２列以上形成することにより、複数の通気孔１４０を１列形成した場合と比較して、より多くの空気を内部に導入することができる。 Note that the plurality of ventilation holes 140 may be formed in two or more rows along the axial direction. By forming the plurality of ventilation holes 140 in two or more rows along the axial direction, more air can be introduced into the interior than when the plurality of ventilation holes 140 are formed in one row.
　また、図５から図８に示した第２シート状材料１２０を用いて接着剤の塗布量を削減することにより、香味発生物品や喫煙物品に適用された筒状体１００から加熱や燃焼によって生じる接着剤の成分が低減されるので、香味発生物品や喫煙物品の香味や喫味の劣化が抑制される。 In addition, by reducing the amount of adhesive applied using the second sheet-like material 120 shown in FIGS. Since the adhesive component is reduced, deterioration of the flavor and taste of flavor-producing articles and smoking articles is suppressed.
　さらに、接着剤の塗布量を削減することにより、コストも削減される。また、接着剤の塗布量を削減することにより、筒状体１００の製造装置に付着する接着剤の糊カスが低減されるので、製造装置の停止リスクが低減されるとともに、糊カス清掃時間が短縮されて、筒状体１００の生産性を向上させることができる。 Furthermore, by reducing the amount of adhesive applied, costs are also reduced. In addition, by reducing the amount of adhesive applied, the amount of adhesive residue adhering to the manufacturing equipment for the cylindrical body 100 is reduced, so the risk of stopping the manufacturing equipment is reduced, and the time required to clean the adhesive debris is reduced. This makes it possible to improve the productivity of the cylindrical body 100.
　次に、筒状体１００の製造方法について説明する。図９は、本発明の一実施形態に係る筒状体の製造装置を示す構成図である。図９に示した筒状体の製造装置１において、シート状材料供給装置２２のボビン（図示せず）から、適当な幅をもったシート状材料２４が搬送方向３４に引き出され、複数の方向転換ローラ４１を介して長手方向に搬送される。 Next, a method for manufacturing the cylindrical body 100 will be explained. FIG. 9 is a configuration diagram showing a cylindrical body manufacturing apparatus according to an embodiment of the present invention. In the cylindrical body manufacturing apparatus 1 shown in FIG. It is conveyed in the longitudinal direction via the conversion roller 41.
　シート状材料２４は、裁断部２３内において長手方向に裁断される。具体的には、シート状材料２４は、第１の幅を有する第１シート状材料１１０と第２の幅を有する第２シート状材料１２０とに裁断される。裁断された第１シート状材料１１０および第２シート状材料１２０は、方向転換ローラ４１を介して並行して搬送され、横方向搬送ローラ３２により相互に分離される。 The sheet material 24 is cut in the longitudinal direction within the cutting section 23. Specifically, the sheet material 24 is cut into a first sheet material 110 having a first width and a second sheet material 120 having a second width. The cut first sheet material 110 and second sheet material 120 are conveyed in parallel via direction change rollers 41 and separated from each other by lateral conveyance rollers 32.
　第２シート状材料１２０は、方向転換ローラ４１により方向転換された後、糊付け部２５により、長手方向の全長にわたって位置決め接着層１３１、第１継目接着層１３２および第２継目接着層１３３（図４参照）が塗布される（塗布工程）。ここで、位置決め接着層１３１は、線状に位置決め糊（接着剤）が塗布された接着パターンを有する（図５から図８参照）。 After the direction of the second sheet material 120 is changed by the direction changing roller 41, the positioning adhesive layer 131, the first seam adhesive layer 132, and the second seam adhesive layer 133 (FIG. ) is applied (application process). Here, the positioning adhesive layer 131 has an adhesive pattern in which positioning glue (adhesive) is applied in a linear manner (see FIGS. 5 to 8).
　続いて、第２シート状材料１２０は、加湿ノズル２６により加湿される（加湿工程）。加湿ノズル２６は、第２シート状材料１２０の位置決め接着層１３１が塗布された面に、水を噴射する。なお、加湿ノズル２６は、水に代えてアルコールを第２シート状材料１２０に噴射してもよいし、蒸気を第２シート状材料１２０に噴霧してもよい。 Subsequently, the second sheet material 120 is humidified by the humidification nozzle 26 (humidification step). The humidifying nozzle 26 sprays water onto the surface of the second sheet material 120 on which the positioning adhesive layer 131 is applied. Note that the humidifying nozzle 26 may spray alcohol onto the second sheet material 120 instead of water, or may spray steam onto the second sheet material 120.
　これにより、第２シート状材料１２０の位置決め接着層１３１、第１継目接着層１３２および第２継目接着層１３３が塗布された箇所とその他の箇所との湿度が同等になり、後の工程で第２シート状材料１２０を筒状に成形する際、均一に変形させることができるので、真円性の高い筒状体１００を得ることができる。 As a result, the humidity of the area where the positioning adhesive layer 131, the first seam adhesive layer 132, and the second seam adhesive layer 133 of the second sheet-like material 120 are applied becomes equal to that of the other areas, so that When the two-sheet material 120 is formed into a cylindrical shape, it can be uniformly deformed, so that the cylindrical body 100 with high roundness can be obtained.
　一方、第１シート状材料１１０は、第２シート状材料１２０から分離された状態で搬送され、位置ずらし部２９により、搬送方向に対して横方向に位置がずらされる。その後、引張りローラ対２８により、第１シート状材料１１０と第２シート状材料１２０とが一体化される（接着工程）。 On the other hand, the first sheet-like material 110 is conveyed in a state separated from the second sheet-like material 120, and its position is shifted in the transverse direction with respect to the conveyance direction by the position shifting section 29. Thereafter, the first sheet-like material 110 and the second sheet-like material 120 are integrated by the tension roller pair 28 (bonding step).
　これにより、第１シート状材料１１０と第２シート状材料１２０とが、長手方向に直交する幅方向の端部同士が重ならないように互いにずらして接着される。具体的には、第２シート状材料１２０に塗布された位置決め接着層１３１および第１継目接着層１３２により、第１本体部１１１と第２本体部１２１とが互いに接着される（図４参照）。 As a result, the first sheet-like material 110 and the second sheet-like material 120 are adhered to each other so that their ends in the width direction perpendicular to the longitudinal direction do not overlap with each other. Specifically, the first body portion 111 and the second body portion 121 are bonded to each other by the positioning adhesive layer 131 and the first seam adhesive layer 132 applied to the second sheet material 120 (see FIG. 4). .
　なお、筒状体の製造装置１には、第１シート状材料１１０および第２シート状材料１２０の幅方向の端部を検知するセンサ、および第１シート状材料１１０と第２シート状材料１２０との位置ずれ量を制御するための制御機構が設けられ得る。 Note that the cylindrical body manufacturing apparatus 1 includes a sensor that detects the ends of the first sheet-like material 110 and the second sheet-like material 120 in the width direction, and a sensor that detects the ends of the first sheet-like material 110 and the second sheet-like material 120. A control mechanism may be provided to control the amount of positional deviation between the two.
　次に、互いにずらして接着された第１シート状材料１１０および第２シート状材料１２０は、成形装置３０に搬送される。成形装置３０では、複数の方向転換ローラ４１を介して、無端状の成形ベルト４３がエンドレスに案内されている。成形装置３０に搬送された第１シート状材料１１０および第２シート状材料１２０は、押圧部４４により成形ベルト４３に押圧される。 Next, the first sheet-like material 110 and the second sheet-like material 120, which are adhered to each other while being shifted from each other, are conveyed to the molding device 30. In the forming device 30, an endless forming belt 43 is guided endlessly via a plurality of direction changing rollers 41. The first sheet material 110 and the second sheet material 120 conveyed to the molding device 30 are pressed against the molding belt 43 by the pressing section 44 .
　その後、第１シート状材料１１０および第２シート状材料１２０は、成形装置３０内において、例えば特開２０１８－１２１６２８号公報に記載された公知の方法により、筒状の連続体３１に成形される（成形工程）。このとき、第２シート状材料１２０に塗布された第２継目接着層１３３により、第１延出部１１２と第２延出部１２２とが互いに接着される（図４参照）。 Thereafter, the first sheet-like material 110 and the second sheet-like material 120 are formed into a cylindrical continuous body 31 in the forming device 30 by a known method described in, for example, Japanese Patent Application Publication No. 2018-121628. (molding process). At this time, the first extension part 112 and the second extension part 122 are bonded to each other by the second seam adhesive layer 133 applied to the second sheet material 120 (see FIG. 4).
　続いて、筒状の連続体３１に成形された第１シート状材料１１０および第２シート状材料１２０は、加熱部３７により加熱され、これにより、位置決め接着層１３１、第１継目接着層１３２および第２継目接着層１３３が硬化する。また、加湿ノズル２６により加湿された第２シート状材料１２０も加熱部３７で乾燥する。 Subsequently, the first sheet material 110 and the second sheet material 120 formed into the cylindrical continuous body 31 are heated by the heating unit 37, whereby the positioning adhesive layer 131, the first seam adhesive layer 132, and The second seam adhesive layer 133 is cured. Further, the second sheet material 120 humidified by the humidifying nozzle 26 is also dried in the heating section 37 .
　次に、筒状の連続体３１に成形された第１シート状材料１１０および第２シート状材料１２０は、切断部３８により所定の長さに切断され（切断工程）、筒状体１００が形成される。なお、筒状体の製造装置１において、第１シート状材料１１０と第２シート状材料１２０とは、互いに入れ替わってもよい。 Next, the first sheet-like material 110 and the second sheet-like material 120 formed into the cylindrical continuous body 31 are cut into a predetermined length by the cutting section 38 (cutting step), and the cylindrical body 100 is formed. be done. In addition, in the cylindrical body manufacturing apparatus 1, the first sheet-like material 110 and the second sheet-like material 120 may be replaced with each other.
　続いて、筒状体１００は、香味発生物品や喫煙物品の半製品に組み込まれた後、筒状体１００の外周から内周に向けてレーザ光線が照射され、照射箇所の材料を燃焼させることで、周方向の全周に亘って断続的に、筒状体１００を貫く複数の通気孔１４０が形成される。 Subsequently, after the cylindrical body 100 is incorporated into a semi-finished product of a flavor generating article or a smoking article, a laser beam is irradiated from the outer circumference to the inner circumference of the cylindrical body 100 to burn the material at the irradiated area. A plurality of ventilation holes 140 are formed intermittently throughout the cylindrical body 100 throughout the circumferential direction.
　次に、筒状体の製造装置１を用いて各種実験を行った結果について説明する。まず、加湿ノズル２６による適切な加湿条件を見出すための実験を行った。図１０は、本発明の一実施形態に係る筒状体の製造装置における加湿条件の実験結果を示す説明図である。ここでは、第２シート状材料１２０に、軸方向に平行な直線状に、３本の位置決め糊を塗布した場合（図７参照）について、加湿条件を変えて実験を行った。 Next, the results of various experiments conducted using the cylindrical body manufacturing apparatus 1 will be explained. First, an experiment was conducted to find appropriate humidification conditions using the humidification nozzle 26. FIG. 10 is an explanatory diagram showing experimental results of humidification conditions in a cylindrical body manufacturing apparatus according to an embodiment of the present invention. Here, an experiment was conducted with the humidification conditions changed for the case where three positioning glues were applied to the second sheet material 120 in a straight line parallel to the axial direction (see FIG. 7).
　図１０に示すように、水量、噴射圧力および加湿ノズル２６から第２シート状材料１２０までの距離（加湿ノズル距離）について、加湿条件を水準１から水準９まで変えながら筒状体１００を製造したところ、真円性および円周長において、水準６（水量６．３４ｍｇ／本、噴射圧力０．０５ＭＰａ、加湿ノズル距離１７ｍｍ）が適切であることが確認された。 As shown in FIG. 10, the cylindrical body 100 was manufactured while changing the humidification conditions from level 1 to level 9 regarding the amount of water, the injection pressure, and the distance from the humidification nozzle 26 to the second sheet material 120 (humidification nozzle distance). However, it was confirmed that level 6 (water amount 6.34 mg/bottle, injection pressure 0.05 MPa, humidifying nozzle distance 17 mm) was appropriate in terms of roundness and circumferential length.
　続いて、図１０に示した水準６により、第２シート状材料１２０に、軸方向に沿ってらせん状に位置決め糊を塗布した筒状体１００（図６参照）を製造したところ、第２継目接着層１３３による第１延出部１１２と第２延出部１２２との接着（図４参照）が適切に行われなかった。 Subsequently, according to the level 6 shown in FIG. 10, a cylindrical body 100 (see FIG. 6) in which positioning glue was applied spirally along the axial direction to the second sheet material 120 was manufactured. The first extending portion 112 and the second extending portion 122 were not properly bonded together by the adhesive layer 133 (see FIG. 4).
　そこで、第２シート状材料１２０に、軸方向に沿ってらせん状に位置決め糊を塗布した筒状体１００（図６参照）について、水量を変えながら実験を行った。この結果、らせん状に位置決め糊を塗布した筒状体１００については、水量２８．２０ｍｇ／本が適切であることが確認された。筒状体の製造装置１における接着パターンごとの加湿条件を図１１に示す。 Therefore, an experiment was conducted while changing the amount of water on the cylindrical body 100 (see FIG. 6) in which positioning glue was applied spirally along the axial direction to the second sheet-like material 120. As a result, it was confirmed that the water amount of 28.20 mg/piece was appropriate for the cylindrical body 100 coated with positioning glue in a spiral shape. FIG. 11 shows humidification conditions for each adhesive pattern in the cylindrical body manufacturing apparatus 1.
　次に、第２シート状材料１２０に、軸方向に沿ってらせん状に位置決め糊を塗布した筒状体１００（図６参照）、および第２シート状材料１２０に、軸方向に平行な直線状に、２本の位置決め糊を塗布した筒状体１００（図５参照）について、位置決め接着層１３１の塗布量を変えて実験を行った。 Next, the second sheet-like material 120 is coated with positioning glue in a spiral shape along the axial direction (see FIG. 6), and the second sheet-like material 120 is coated with positioning glue in a straight line parallel to the axial direction. Next, an experiment was conducted on a cylindrical body 100 (see FIG. 5) coated with two positioning adhesives, while changing the amount of the positioning adhesive layer 131 applied.
　この結果、らせん状に位置決め糊を塗布した筒状体１００については、塗布量２０ｇ／５００ｍ（４．８ｍｇ／本）が適切であり、２本の位置決め糊を塗布した筒状体１００については、２５ｇ／５００ｍ（３．０ｍｇ／本×２）が適切であることが確認された。筒状体１００における位置決め接着層１３１の塗布量を従来品と比較した結果を図１２に示す。 As a result, for the cylindrical body 100 coated with positioning glue in a spiral shape, an application amount of 20g/500m (4.8mg/piece) is appropriate, and for the cylindrical body 100 coated with two strands of positioning glue, It was confirmed that 25g/500m (3.0mg/piece x 2) was appropriate. FIG. 12 shows the results of comparing the coating amount of the positioning adhesive layer 131 on the cylindrical body 100 with that of a conventional product.
　図１２に示すように、らせん状に位置決め糊を塗布した筒状体１００では、従来品（塗布量１００ｇ／５００ｍ（２４ｍｇ／本））と比較して、位置決め接着層１３１の塗布量を８０％削減することができる。また、２本の位置決め糊を塗布した筒状体１００では、従来品と比較して、位置決め接着層１３１の塗布量を７５％削減することができる。 As shown in FIG. 12, in the cylindrical body 100 coated with positioning glue in a spiral shape, the coating amount of the positioning adhesive layer 131 is 80% compared to the conventional product (coating amount: 100 g/500 m (24 mg/piece)). can be reduced. Further, in the case of the cylindrical body 100 coated with two positioning adhesives, the amount of the positioning adhesive layer 131 applied can be reduced by 75% compared to the conventional product.
　続いて、図１１および図１２に示した加湿条件および位置決め接着層１３１の塗布量で、第２シート状材料１２０に、軸方向に沿ってらせん状に位置決め糊を塗布した筒状体１００（図６参照）、および第２シート状材料１２０に、軸方向に平行な直線状に、２本の位置決め糊を塗布した筒状体１００（図５参照）を製造し、各種物性を測定した。筒状体１００の各種物性を規格品よび従来品と比較した結果を図１３に示す。 Subsequently, the cylindrical body 100 (Fig. 6), and a cylindrical body 100 (see FIG. 5) in which two positioning glues were applied in a straight line parallel to the axial direction to the second sheet-like material 120 were manufactured, and various physical properties were measured. FIG. 13 shows the results of comparing various physical properties of the cylindrical body 100 with a standard product and a conventional product.
　ここで、らせん状に位置決め糊を塗布した筒状体１００および２本の位置決め糊を塗布した筒状体１００については、加湿ノズル２６による加湿の影響を考慮して、筒状体１００の形成直後および２４時間後の物性を測定した。また、水分は、１週間後の値を測定した。 Here, regarding the cylindrical body 100 coated with positioning glue in a spiral shape and the cylindrical body 100 coated with two positioning glues, in consideration of the influence of humidification by the humidifying nozzle 26, immediately after the formation of the cylindrical body 100, And the physical properties were measured after 24 hours. Moreover, the moisture content was measured after one week.
　図１３に示すように、筒状体１００の形成直後では、従来品と同等の重量であるものの、時間が経つにつれて水分が減少し、重量が軽くなる傾向にあることが確認された。また、円周長や硬さについても、時間が経つにつれて水分が減少し、値が変化することが確認された。 As shown in FIG. 13, it was confirmed that immediately after the cylindrical body 100 was formed, it had the same weight as the conventional product, but as time passed, the water content decreased and the weight tended to become lighter. It was also confirmed that the circumference length and hardness values changed as time passed as water content decreased.
　また、らせん状に位置決め糊を塗布した筒状体１００および２本の位置決め糊を塗布した筒状体１００のいずれについても、真円性が規格品と同等であることが確認された。また、らせん状に位置決め糊を塗布した筒状体１００および２本の位置決め糊を塗布した筒状体１００のいずれについても、第１延出部１１２と第２延出部１２２との継目部分の構造が従来品と同様であることから、継目剥離強度は、従来品と同等の値を示す。 Furthermore, it was confirmed that the roundness of both the cylindrical body 100 coated with positioning glue in a spiral shape and the cylindrical body 100 coated with two pieces of positioning glue was equivalent to that of the standard product. Furthermore, for both the cylindrical body 100 coated with positioning glue in a spiral shape and the cylindrical body 100 coated with two positioning glues, the joint portion between the first extension part 112 and the second extension part 122 is Since the structure is the same as the conventional product, the seam peel strength shows the same value as the conventional product.
　また、位置決め接着層１３１の面積を、第１本体部と第２本体部との重なり部分の面積の１０％以上５０％以下とすることにより、第１シート状材料１１０と第２シート状材料１２０との接着不良を抑制し、真円性に優れ、香味や喫味への影響が少ない筒状体を得ることができる。 Furthermore, by setting the area of the positioning adhesive layer 131 to 10% or more and 50% or less of the area of the overlapping portion of the first body part and the second body part, the first sheet-like material 110 and the second sheet-like material 120 can be It is possible to obtain a cylindrical body that suppresses poor adhesion with the cylindrical body, has excellent roundness, and has little effect on flavor and taste.
