Description
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。ここで、接着剤は、材料条片部分の表面全体に対して、少なくとも８０％、有利には少なくとも９０％、特に有利には少なくとも９５％の割合で塗布される。
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. Here, the adhesive is applied to a proportion of at least 80%, preferably at least 90% and particularly preferably at least 95% of the entire surface of the material strip section.
特許文献１に記載の小管体では、接着剤が、材料条片部分の表面全体に対して、少なくとも８０％、有利には少なくとも９０％、特に有利には少なくとも９５％の割合で塗布される。しかしながら、接着剤の塗布量が多くなると、小管体が適用される香味発生物品や喫煙物品の香味や喫味が劣化するおそれがある。
In the tubular body according to DE 10 2005 010 100, the adhesive is applied to a proportion of at least 80%, preferably at least 90% and particularly preferably at least 95% of the entire surface of the material strip section. However, when the amount of adhesive applied increases, there is a risk that the flavor and taste of the flavor-producing article or smoking article to which the small tube is applied may deteriorate.
すなわち、接着剤の塗布量が多い小管体が香味発生物品や喫煙物品に適用されると、香味発生物品の加熱や喫煙物品の燃焼によってエアロゾルが発生する際、接着剤から多くの成分が揮散する。揮散した接着剤の成分は、香味発生物品や喫煙物品から発生するエアロゾルに混入し、香味発生物品や喫煙物品の香味や喫味を劣化させる。
In other words, if a small tube with a large amount of adhesive applied is applied to a flavor-producing article or a smoking article, many components will volatilize from the adhesive when aerosol is generated by heating the flavor-producing article or burning the smoking article. . The volatilized adhesive components mix into aerosols generated from flavor-generating articles and smoking articles, and deteriorate the flavor and taste of the flavor-generating articles and smoking articles.

Here, the first sheet-like material 110 and the second sheet-like material 120 are stacked on top of each other so that their ends in the circumferential direction do not overlap. 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-like material 120 in FIG.
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３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.
接着層１３０は、第１本体部１１１と第２本体部１２１とを互いに接着する位置決め接着層１３１および第１継目接着層１３２と、第１延出部１１２と第２延出部１２２とを互いに接着する第２継目接着層１３３（継目接着層）とを有する。なお、第１継目接着層１３２は、必ずしも設けられる必要はなく、位置決め接着層１３１が第１継目接着層１３２として機能してもよい。
The adhesive layer 130 includes a positioning adhesive layer 131 and a first seam adhesive layer 132 that adhere the first body part 111 and the second body part 121 to each other, and a positioning adhesive layer 131 and a first seam adhesive layer 132 that adhere the first body part 111 and the second body part 121 to each other. 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.
図４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。具体的には、図４は、筒状に成形される前の状態を示している。図４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. 4 is a developed view showing the second sheet-like material of the cylindrical body according to an embodiment of the present invention. Specifically, FIG. 4 shows the state before being formed into a cylindrical shape. As shown in FIG. 4, 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。
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.
なお、位置決め接着層１３１の接着パターンは、図４に示したものに限定されない。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別の展開図である。具体的には、図５は、筒状に成形される前の状態を示している。図５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. 4. FIG. 5 is another developed view showing the second sheet-like material of the cylindrical body according to an embodiment of the present invention. Specifically, FIG. 5 shows the state before being formed into a cylindrical shape. As shown in FIG. 5, 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。
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.
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。具体的には、図６は、筒状に成形される前の状態を示している。図６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. 6 is another developed view showing the second sheet-like material of the cylindrical body according to an embodiment of the present invention. Specifically, FIG. 6 shows the state before being formed into a cylindrical shape. As shown in FIG. 6, 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。
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.
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。具体的には、図７は、筒状に成形される前の状態を示している。図７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. 7 is another developed view showing the second sheet material of the cylindrical body according to an embodiment of the present invention. Specifically, FIG. 7 shows the state before being formed into a cylindrical shape. As shown in FIG. 7, the second sheet-like 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。
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.
また、図４から図７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. 4 to 7, it is possible to reduce the amount of adhesive that is produced by heating or burning from the cylindrical body 100 applied to flavor-producing articles or smoking articles. 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.
なお、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を貫く通気孔が形成され得る。このとき、接着剤を第１シート状材料１１０と第２シート状材料１２０との間の全面に塗布すると、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。
In addition, 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 periphery to the inner periphery of the cylindrical body 100, and the material at the irradiated area is burned. , ventilation holes penetrating the cylindrical body 100 may be formed intermittently over the entire circumference in the circumferential direction. At this time, if the adhesive is applied to the entire surface between the first sheet-like material 110 and the second sheet-like material 120, there is a risk that the combustion ash of the adhesive will clog the vent when forming the vent.
筒状体１００を構成する紙は、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。
The paper constituting the cylindrical body 100 is made of organic wood pulp (almost pure cellulose from which lignin, hemicellulose, etc. contained in trees have been removed) and an inorganic filler (calcium carbonate), and cannot be irradiated with a laser beam. The combustion ash produced by this method is mainly composed of calcium carbonate.
これに対して、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, the positioning adhesive layer 131, the first seam adhesive layer 132, and the second seam adhesive layer 133 are made of, for example, a mixture of organic polymers such as modified starch, vinyl acetate, or ethylene vinyl acetate, alcohol, and water. It is a forged product, and the combustion ash produced by laser beam irradiation is mixed with organic polymers left over from combustion.
そのため、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、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 the vents formed at the locations where the positioning adhesive layer 131, the first seam adhesive layer 132, and the second seam adhesive layer 133 are applied is a mixture of calcium carbonate and organic polymer, and The ash is more sticky and tends to block the air holes than the combustion ash mainly composed of calcium carbonate in the air holes formed in the areas where the adhesive layer 131, the first seam adhesive layer 132, and the second seam adhesive layer 133 are not applied.
そこで、図４から図７に示したように、第２シート状材料１２０に塗布される位置決め接着層１３１を、線状に位置決め糊（接着剤）が塗布された接着パターンとすることにより、位置決め接着層を全面に設ける場合と比較して、位置決め接着層１３１が塗布された箇所に通気孔が形成される確率を低減することができ、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。
Therefore, as shown in FIGS. 4 to 7, the positioning adhesive layer 131 applied to the second sheet material 120 is formed into an adhesive pattern in which positioning glue (adhesive) is applied in a linear manner. Compared to the case where the adhesive layer is provided on the entire surface, the probability that a vent hole will be formed in the area where the positioning adhesive layer 131 is applied can be reduced, and the combustion ash of the adhesive can be suppressed from clogging the vent hole. can do.
次に、筒状体１００の製造方法について説明する。図８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８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. 8 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. 8, a sheet material 24 having an appropriate width is pulled out from a bobbin (not shown) of a sheet material supply device 22 in a conveying direction 34, and is drawn out in a plurality of directions. 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３参照）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４から図７参照）。
After the direction of the second sheet-like 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 paste (adhesive) is applied in a linear manner (see FIGS. 4 to 7).
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３参照）。
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 part 111 and the second body part 121 are adhered to each other by the positioning adhesive layer 131 and the first seam adhesive layer 132 applied to the second sheet-like material 120 (see FIG. 3). .
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３参照）。
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 adhered to each other by the second seam adhesive layer 133 applied to the second sheet material 120 (see FIG. 3).
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.
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９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６参照）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. 9 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 different humidification conditions 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. 6).
図９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. 9, 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９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５参照）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３参照）が適切に行われなかった。
Subsequently, according to the level 6 shown in FIG. 9, a cylindrical body 100 (see FIG. 5) was manufactured by applying positioning glue to the second sheet material 120 in a spiral shape along the axial direction. The first extending portion 112 and the second extending portion 122 were not properly bonded together by the adhesive layer 133 (see FIG. 3).
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５参照）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１０に示す。
Therefore, an experiment was conducted on the cylindrical body 100 (see FIG. 5) in which positioning glue was applied spirally along the axial direction to the second sheet-like material 120 while changing the amount of water. 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. 10 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５参照）、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４参照）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. 5), 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 the cylindrical body 100 (see FIG. 4) coated with two pieces of positioning glue, 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１１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. 11 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.
