　以下、図面を参照しながらこの発明を実施するための形態について説明する。 Below, we will explain the form for implementing this invention with reference to the drawings.
　（第１実施形態）
　第１実施形態について、図１から図９を用いて説明する。 First Embodiment
The first embodiment will be described with reference to FIGS. 1 to 9. FIG.
　図１に示すように、香味吸引物品１０は、香味生成セグメント（ロッドセグメント）１２と、香味生成セグメント１２の下流側に設けられるマウスピースセグメント（ロッドセグメント）１４と、香味生成セグメント１２及びマウスピースセグメント１４を連結するチップペーパ１６とを有する。 As shown in FIG. 1, the flavor inhalation article 10 has a flavor generating segment (rod segment) 12, a mouthpiece segment (rod segment) 14 provided downstream of the flavor generating segment 12, and tipping paper 16 connecting the flavor generating segment 12 and the mouthpiece segment 14.
　香味生成セグメント１２及びマウスピースセグメント１４はそれぞれ略円柱状（断面が略円形）のロッドとして形成されることが好適である。すなわち、香味生成セグメント１２及びマウスピースセグメント１４はそれぞれロッド又はロッドセグメントの１つである。なお、後述するフィルタセグメント２０、先端プラグ４２、香味生成部４４等も、ロッド又はロッドセグメントの１つとなる。 The flavor generating segment 12 and the mouthpiece segment 14 are preferably each formed as a rod having a substantially cylindrical shape (a substantially circular cross section). In other words, the flavor generating segment 12 and the mouthpiece segment 14 are each a rod or a rod segment. The filter segment 20, tip plug 42, flavor generating section 44, etc., described below, are also rods or rod segments.
　香味吸引物品１０は、香味生成セグメント１２を燃焼させず、加熱する非燃焼加熱式製品であっても、香味生成セグメント１２を燃焼させる燃焼式製品であってもよい。また、香味吸引物品１０は、非燃焼非加熱式製品であってもよい。 The flavor inhalation article 10 may be a non-combustion, heating type product that heats the flavor generating segment 12 without burning it, or a combustion type product that burns the flavor generating segment 12. The flavor inhalation article 10 may also be a non-combustion, non-heating type product.
　香味生成セグメント１２は、適宜の充填物を巻紙で巻いて円柱状のロッドとして形成される。充填物は、種々のものを用いることができる。 The flavor generating segment 12 is formed into a cylindrical rod by wrapping a suitable filling material in wrapping paper. Various filling materials can be used.
　非燃焼加熱式の香味生成セグメント１２の充填物として、例えば、たばこ刻、たばこシート材等を使用できる。具体的には、乾燥したたばこ葉を幅０．８ｍｍ～１．２ｍｍに裁刻したたばこ刻を巻紙内に充填してよい。また、乾燥したたばこ葉を平均粒径が２０μｍ～２００μｍ程度になるように粉砕して均一化したものをシート材として加工し、それを幅０．８ｍｍ～１．２ｍｍに裁刻したものを巻紙内に充填してもよい。当該シート材を裁刻せずにギャザー加工、折り畳み、あるいは渦巻き状にして巻紙内に充填してもよい。当該シート材を短冊状に裁断してこれらを巻紙内に、同心円状にあるいは短冊の長手方向が香味生成セグメント１２のロッドの長手方向と平行になるように充填してもよい。香味生成セグメント１２は、加熱に伴ってエアロゾルを発生するようにしてもよい。エアロゾルの発生を促進するために、充填物の一部として、グリセリン、プロピレングリコール、１，３－ブタンジオール等のポリオール等のエアロゾル源を添加することが好ましい。エアロゾル源の添加量は、充填物の乾燥重量に対して５重量％～５０重量％が好ましく、１０重量％～３０重量％がより好ましい。この他、香味生成セグメント１２はメントール等の香料を含んでいてもよい。 For example, tobacco shreds, tobacco sheet material, etc. can be used as the filling material for the non-combustion heating flavor generating segment 12. Specifically, tobacco shreds obtained by cutting dried tobacco leaves to a width of 0.8 mm to 1.2 mm may be filled into the cigarette paper. Dried tobacco leaves may also be crushed and homogenized to an average particle size of about 20 μm to 200 μm, processed into a sheet material, and then cut into a width of 0.8 mm to 1.2 mm and filled into the cigarette paper. The sheet material may be gathered, folded, or spirally wound without being cut into pieces and filled into the cigarette paper. The sheet material may be cut into strips and filled into the cigarette paper concentrically or with the longitudinal direction of the strips parallel to the longitudinal direction of the rod of the flavor generating segment 12. The flavor generating segment 12 may generate an aerosol when heated. In order to promote the generation of aerosols, it is preferable to add an aerosol source such as a polyol, such as glycerin, propylene glycol, or 1,3-butanediol, as part of the filling. The amount of the aerosol source added is preferably 5% to 50% by weight, more preferably 10% to 30% by weight, based on the dry weight of the filling. In addition, the flavor generating segment 12 may contain a flavoring such as menthol.
　燃焼式の香味生成セグメント１２の充填物として、非燃焼加熱式の香味生成セグメント１２の充填物と同様に、例えば、たばこ刻、たばこシート材等を使用できる。具体的には、乾燥したたばこ葉を幅０．８ｍｍ～１．２ｍｍに裁刻したたばこ刻を巻紙内に充填してよい。また、乾燥したたばこ葉を平均粒径が２０μｍ～２００μｍ程度になるように粉砕して均一化したものをシート材として加工し、それを幅０．８ｍｍ～１．２ｍｍに裁刻したものを巻紙内に充填してもよい。当該シート材を裁刻せずにギャザー加工、折り畳み、あるいは渦巻き状にして巻紙内に充填してもよい。当該シート材を短冊状に裁断してこれらを巻紙内に、同心円状にあるいは短冊の長手方向がたばこロッドの長手方向と平行になるように充填してもよい。 As the filling material for the combustion flavor generation segment 12, for example, tobacco shreds, tobacco sheet material, etc. can be used, as with the filling material for the non-combustion heating flavor generation segment 12. Specifically, tobacco shreds obtained by cutting dried tobacco leaves to a width of 0.8 mm to 1.2 mm may be filled into the cigarette paper. Alternatively, dried tobacco leaves may be crushed and homogenized to an average particle size of about 20 μm to 200 μm, processed into a sheet material, and then cut into a width of 0.8 mm to 1.2 mm and filled into the cigarette paper. The sheet material may be gathered, folded, or spirally wound without being cut into pieces, and filled into the cigarette paper. The sheet material may be cut into strips, and these may be filled into the cigarette paper concentrically, or with the longitudinal direction of the strips parallel to the longitudinal direction of the tobacco rod.
　香味生成セグメント１２のロッドの長さは、適宜に設定可能である。香味生成セグメント１２のロッドの長さは、例えば１５ｍｍから７０ｍｍであることが好適である。香味生成セグメント１２のロッドの直径は、先端面（吸口端１４ｂとは反対側の香味生成セグメント１２の端面）１２ａから後端面１２ｂまで略一定であり、適宜に設定可能である。香味生成セグメント１２のロッドの直径は、例えば４ｍｍから１０ｍｍであることが好適であり、６ｍｍから８ｍｍであることがより好適である。 The length of the rod of the flavor generation segment 12 can be set as appropriate. The length of the rod of the flavor generation segment 12 is preferably, for example, 15 mm to 70 mm. The diameter of the rod of the flavor generation segment 12 is approximately constant from the tip face (the end face of the flavor generation segment 12 opposite the mouth end 14b) 12a to the rear end face 12b, and can be set as appropriate. The diameter of the rod of the flavor generation segment 12 is preferably, for example, 4 mm to 10 mm, and more preferably 6 mm to 8 mm.
　マウスピースセグメント１４は、本実施形態では、フィルタセグメント（ロッドセグメント）２０を有する。フィルタセグメント２０のシート材３０は、本実施形態では、例えば紙材、不織布材、樹脂材等の材料を円柱状に加工したものを用いることができる。フィルタセグメント２０は、例えば、ユーザがエアロゾル等を吸引する際に混ざる空気量の調整や、喫味の軽減、ニコチンやタールの軽減等の機能を担う。フィルタセグメント２０は、これらの機能を全て備えていることは要しない。また、燃焼型香味吸引物品１０と比較して、生成される香味成分が少なく、また、たばこ充填物の充填率が低くなる傾向のある非燃焼加熱型香味吸引物品１０においては、濾過機能を抑えつつたばこ充填物の落下を防止する機能を発揮し得る。 In this embodiment, the mouthpiece segment 14 has a filter segment (rod segment) 20. In this embodiment, the sheet material 30 of the filter segment 20 can be, for example, a paper material, a nonwoven fabric material, a resin material, or the like, processed into a cylindrical shape. The filter segment 20 performs functions such as adjusting the amount of air mixed in when the user inhales aerosols, reducing the smoking taste, and reducing nicotine and tar. The filter segment 20 does not need to have all of these functions. Furthermore, in the non-combustion heating type flavor inhalation article 10, which tends to generate fewer flavor components and has a lower tobacco filling rate compared to the combustion type flavor inhalation article 10, the filter segment 20 can suppress the filtering function while preventing the tobacco filling from falling.
　なお、マウスピースセグメント１４は、非燃焼加熱式香味吸引物品１０の一部として形成される場合、冷却セグメント４６を有し得る。これについては、第２実施形態の第２変形例（図１７参照）に後述する。すなわち、本実施形態では、マウスピースセグメント１４とフィルタセグメント２０とが同じものである、として説明する。 When the mouthpiece segment 14 is formed as a part of the non-combustion heating type flavor inhalation article 10, it may have a cooling segment 46. This will be described later in the second modified example of the second embodiment (see FIG. 17). That is, in this embodiment, the mouthpiece segment 14 and the filter segment 20 will be described as being the same thing.
　マウスピースセグメント１４のロッドの長さは、例えば１０ｍｍから５０ｍｍであることが好適であり、２５ｍｍから３０ｍｍ程度がより好適である。マウスピースセグメント１４のロッドの直径は、先端面１４ａから後端面（吸口端）１４ｂまで略一定であり、例えば４ｍｍから１０ｍｍであることが好適であり、６ｍｍから８ｍｍであることがより好適である。 The length of the rod of the mouthpiece segment 14 is preferably, for example, 10 mm to 50 mm, and more preferably, approximately 25 mm to 30 mm. The diameter of the rod of the mouthpiece segment 14 is approximately constant from the tip surface 14a to the rear end surface (mouth end) 14b, and is preferably, for example, 4 mm to 10 mm, and more preferably, 6 mm to 8 mm.
　香味生成セグメント１２の直径及びマウスピースセグメント１４の直径は同じ又は略同じであり、チップペーパ１６は、香味生成セグメント１２の後端面１２ｂとマウスピースセグメント１４の先端面１４ａとを突き合わせた状態で、香味生成セグメント１２の後端面１２ｂ及びマウスピースセグメント１４の先端面１４ａを含む外周に巻かれる。このため、香味生成セグメント１２のロッド及びマウスピースセグメント１４のロッドが軸方向に並んだ香味吸引物品１０が形成される。 The diameter of the flavor generating segment 12 and the diameter of the mouthpiece segment 14 are the same or approximately the same, and the tipping paper 16 is wrapped around the outer circumference including the rear end surface 12b of the flavor generating segment 12 and the tip surface 14a of the mouthpiece segment 14 with the rear end surface 12b of the flavor generating segment 12 and the tip surface 14a of the mouthpiece segment 14 butted against each other. As a result, a flavor inhalation article 10 is formed in which the rods of the flavor generating segment 12 and the rods of the mouthpiece segment 14 are aligned in the axial direction.
　フィルタセグメント２０は、フィルタ材２２と、フィルタ材２２の外側を巻装し、フィルタセグメント２０をロッドとして形成するラッパー（巻取紙）２４とを含む。
　フィルタセグメント２０のフィルタ材２２は、部分的に打ち抜かれている打ち抜き領域（第１のセグメント）３２と、打ち抜かれていないホールレス領域（第２のセグメント）３４とを有する、図２に示すシート材３０を加工して形成される。打ち抜き領域３２とホールレス領域３４とはシート材３０の長手方向（軸方向）に隣接して配置されている。フィルタセグメント２０のフィルタ材２２は、後述するが、シート材３０の、打ち抜き領域３２とホールレス領域３４とを有する１つのセグメントＳを加工して形成されている。 The filter segment 20 includes a filter material 22 and a wrapper 24 that is wrapped around the outside of the filter material 22 and forms the filter segment 20 into a rod.
The filter material 22 of the filter segment 20 is formed by processing a sheet material 30 shown in Figure 2, which has a punched region (first segment) 32 that is partially punched out and a holeless region (second segment) 34 that is not punched out. The punched region 32 and the holeless region 34 are disposed adjacent to each other in the longitudinal direction (axial direction) of the sheet material 30. As will be described later, the filter material 22 of the filter segment 20 is formed by processing one segment S of the sheet material 30, which has the punched region 32 and the holeless region 34.
　フィルタセグメント２０は、後述するロッド製造装置５０により、実際に使用されるフィルタセグメント２０の例えば４倍又は６倍の長さのフィルタアセンブリ（ロッドアセンブリ）１８から形成される。そして、フィルタセグメント２０は、フィルタアセンブリ１８を所定位置で所定長さに切断することにより形成される。すなわち、フィルタセグメント２０は、例えば２段階の切断により形成される。１段階目は、連続するシート材３０を捲縮してラッパー２４で巻いたフィルタアセンブリ１８を、実際に香味吸引物品１０の一部として用いるフィルタセグメント２０の例えば４倍又は６倍の長さに切断する工程である。２段階目は、所望の長さの４倍又は６倍の長さのフィルタセグメント２０を、実際に香味吸引物品１０の一部として用いるフィルタセグメント２０の長さに切断する工程である。このため、２段階目におけるフィルタアセンブリ１８の切断により、フィルタアセンブリ１８から４つ又は６つのフィルタセグメント２０が形成される。２段階目におけるフィルタアセンブリ１８の切断は、複数回の切断により行われてもよい。 The filter segment 20 is formed from a filter assembly (rod assembly) 18 having a length, for example, four or six times that of the filter segment 20 to be actually used, by a rod manufacturing device 50 described later. The filter segment 20 is formed by cutting the filter assembly 18 to a predetermined length at a predetermined position. That is, the filter segment 20 is formed by, for example, cutting in two stages. The first stage is a process of cutting the filter assembly 18, which is made by crimping a continuous sheet material 30 and wrapping it with a wrapper 24, to a length, for example, four or six times that of the filter segment 20 to be actually used as a part of the flavor inhalation article 10. The second stage is a process of cutting the filter segment 20 having a length four or six times the desired length to the length of the filter segment 20 to be actually used as a part of the flavor inhalation article 10. Therefore, by cutting the filter assembly 18 in the second stage, four or six filter segments 20 are formed from the filter assembly 18. The cutting of the filter assembly 18 in the second stage may be performed by multiple cuts.
　なお、図２には、ＸＹＺ直交座標系を規定する。Ｘ軸に沿う方向は、シート材３０の軸方向（切断される前は長手方向）、かつ、搬送方向である。Ｙ軸に沿う方向は、シート材３０の幅方向である。Ｚ軸に沿う方向は、シート材３０の厚さ方向である。 In addition, FIG. 2 defines an XYZ Cartesian coordinate system. The direction along the X axis is the axial direction of the sheet material 30 (the longitudinal direction before being cut) and the conveying direction. The direction along the Y axis is the width direction of the sheet material 30. The direction along the Z axis is the thickness direction of the sheet material 30.
　上述したように、フィルタ材２２は、図２に示すシート材３０を加工して形成される。フィルタ材２２は、例えば、紙材製のシート材、不織布材製のシート材、又は、樹脂材製のシート材３０を加工して形成される。本実施形態では、フィルタ材２２が紙材製のシート材３０で形成される例、すなわち、ペーパフィルタとしての例について説明する。紙材製のシート材３０は、例えば木材パルプを抄紙して得られる紙である。ペーパフィルタは、紙材製のシート材３０をフィルタ材２２とし、フィルタ材２２の外側を巻取紙２４で巻装しロッド形状としたものであり、、生分解性に優れた生分解性フィルタである。
　シート材３０の幅方向の幅は、例えば１５０ｍｍから２５０ｍｍの間など、適宜の大きさに形成される。これは、シート材３０の厚さ、製造するフィルタセグメント２０の直径等により調整される。また、シート材３０として、後述するように、たばこシート材や冷却用のシート材を用いる場合は、機能に合わせて、シート材３０の素材、幅方向の幅及び厚さが調整される。 As described above, the filter material 22 is formed by processing the sheet material 30 shown in Fig. 2. The filter material 22 is formed, for example, by processing a sheet material made of paper, a sheet material made of nonwoven fabric, or a sheet material 30 made of resin. In this embodiment, an example in which the filter material 22 is formed from a sheet material made of paper, that is, an example as a paper filter, will be described. The sheet material made of paper 30 is, for example, paper obtained by papermaking wood pulp. The paper filter is a biodegradable filter in which the paper sheet material 30 is used as the filter material 22 and the outside of the filter material 22 is wrapped with wrapping paper 24 to form a rod shape, and is an excellent biodegradable filter.
The width of the sheet material 30 in the width direction is formed to an appropriate size, for example, between 150 mm and 250 mm. This is adjusted according to the thickness of the sheet material 30, the diameter of the filter segment 20 to be manufactured, etc. Furthermore, when a tobacco sheet material or a cooling sheet material is used as the sheet material 30, as described below, the material, width in the width direction, and thickness of the sheet material 30 are adjusted according to the function.
　図２に示すように、シート材３０の長手方向に沿って、打ち抜き領域３２とホールレス領域３４とが交互に、すなわち、繰り返して形成される。シート材３０は、１つの打ち抜き領域３２と、その打ち抜き領域３２に隣接するホールレス領域３４とを１つの組とするセグメントＳが繰り返し形成される。シート材３０の長手方向は、打ち抜き領域３２とホールレス領域３４とが隣接して配置される方向に沿う方向である。シート材３０の幅方向は、打ち抜き領域３２とホールレス領域３４とが隣接して配置される方向に交差する方向であり、好ましくは直交する方向である。なお、フィルタセグメント２０のロッドの長さは、例えば、１つの打ち抜き領域３２と１つのホールレス領域３４とを合わせた、シート材３０の１つのセグメントＳの長さとして形成される。 2, punched regions 32 and holeless regions 34 are alternately, i.e., repeatedly, formed along the longitudinal direction of the sheet material 30. The sheet material 30 is repeatedly formed with segments S, each of which is a pair of one punched region 32 and a holeless region 34 adjacent to the punched region 32. The longitudinal direction of the sheet material 30 is the direction along which the punched regions 32 and the holeless region 34 are adjacently arranged. The width direction of the sheet material 30 is a direction intersecting the direction in which the punched regions 32 and the holeless region 34 are adjacently arranged, and is preferably perpendicular to this direction. The length of the rod of the filter segment 20 is formed as the length of one segment S of the sheet material 30, which is, for example, the combined length of one punched region 32 and one holeless region 34.
　シート材３０のホールレス領域３４は、シート材３０の長手方向と幅方向とで規定する領域のいずれの位置にもＺ軸方向に貫通する孔がない閉塞領域（区画）として形成される。 The holeless region 34 of the sheet material 30 is formed as a closed region (partition) that has no holes penetrating in the Z-axis direction at any position in the region defined by the longitudinal and transverse directions of the sheet material 30.
　打ち抜き領域３２はシート材３０に、Ｚ軸方向に貫通する複数の開口（開口縁）３３を形成する。各打ち抜き領域３２には、例えば同形状に複数の開口３３が幅方向に間隔を開けて形成される。本実施形態では、複数の開口３３は、それぞれ同形状で同一の大きさの略矩形状の孔として幅方向に等間隔に形成される。開口３３の形状は、略矩形状のほか、略多角形状、略円形状、略楕円形状等、適宜に形成される。複数の開口３３の縁部には、それぞれ角部がないことが好適である。 The punched regions 32 form a plurality of openings (opening edges) 33 penetrating the sheet material 30 in the Z-axis direction. In each punched region 32, a plurality of openings 33 of the same shape are formed at intervals in the width direction. In this embodiment, the plurality of openings 33 are formed as substantially rectangular holes of the same shape and size at equal intervals in the width direction. The shape of the openings 33 may be a substantially rectangular shape, or may be a substantially polygonal shape, a substantially circular shape, a substantially elliptical shape, or any other suitable shape. It is preferable that the edges of the plurality of openings 33 do not have corners.
　なお、シート材３０の幅方向の両端にも、開口３３の一部が形成されてもよいが、シート材３０をロッドとして形成する形成時にロッド製造装置５０の例えば集束ガイド７４（図４参照）等に引っかかることを抑制するため、シート材３０の幅方向の両端には、開口３３が形成されていないことが好適である。 Note that, although a portion of the opening 33 may be formed at both ends of the sheet material 30 in the width direction, it is preferable that no opening 33 is formed at both ends of the sheet material 30 in the width direction in order to prevent the sheet material 30 from getting caught on, for example, the focusing guide 74 (see FIG. 4) of the rod manufacturing device 50 when forming the sheet material 30 into a rod.
　シート材３０に対する打ち抜き領域３２の打ち抜き範囲（開口３３の内側の面積）は任意である。ただし、打ち抜きすぎると、シート材３０をフィルタセグメント２０のロッドとする際に濾材（実部）が少なく、また、フィルタセグメント２０のロッドとしての硬さが低下する。また、濾材（実部）が少ないと、フィルタセグメント２０のロッドとしての強度が下がるため、製造時の製造適性は低下する可能性がある。
　シート材３０の打ち抜き領域３２の打ち抜き範囲は、シート材３０を広げた状態において、シート材３０の長手方向と幅方向とで規定する領域の面積の例えば５％～７０％程度で、好ましくは１０％～５０％程度であることが好適である。打ち抜き領域３２の範囲の下限（打ち抜き領域３２により、シート材３０の実部の面積を多く残すか）は、フィルタセグメント２０の製造者が、どの程度、低濾過性を求めるかに依って変化し得る。打ち抜き領域３２の打ち抜き範囲の上限（打ち抜き領域３２の開口３３により、シート材３０の実部の面積を少なくするか）は、フィルタセグメント２０の製造者が、フィルタセグメント２０としてどの程度の硬さを求めるか、また、製造適性に依って変化し得る。 The punching range of the punching region 32 in the sheet material 30 (the area inside the opening 33) is arbitrary. However, if punching is performed too much, the filter material (solid part) will be small when the sheet material 30 is made into the rod of the filter segment 20, and the hardness of the filter segment 20 as a rod will decrease. Furthermore, if the filter material (solid part) is small, the strength of the filter segment 20 as a rod will decrease, and the manufacturing suitability during manufacturing may decrease.
The punching range of the punching region 32 of the sheet material 30 is, for example, about 5% to 70%, preferably about 10% to 50%, of the area of the region defined by the longitudinal direction and width direction of the sheet material 30 when the sheet material 30 is spread out. The lower limit of the range of the punching region 32 (whether the punching region 32 leaves a large area of the solid part of the sheet material 30) can vary depending on how low the filterability is desired by the manufacturer of the filter segment 20. The upper limit of the punching range of the punching region 32 (whether the openings 33 of the punching region 32 reduce the area of the solid part of the sheet material 30) can vary depending on how hard the manufacturer of the filter segment 20 desires the filter segment 20 to be, and on the manufacturing suitability.
　フィルタセグメント２０のロッドの長手方向において、ホールレス領域３４と打ち抜き領域３２との長さ比は１：５～５：１の範囲や、２：３～３：２の範囲など、適宜に調整される。ホールレス領域３４と打ち抜き領域３２との長さ比は１：１、すなわち、同じ長さでもよい。ホールレス領域３４と打ち抜き領域３２との長さ比は香味吸引物品１０の製造者が適宜に設定可能である。 In the longitudinal direction of the rod of the filter segment 20, the length ratio between the holeless region 34 and the punched region 32 is adjusted as appropriate, for example, in the range of 1:5 to 5:1, or in the range of 2:3 to 3:2. The length ratio between the holeless region 34 and the punched region 32 may be 1:1, i.e., the same length. The length ratio between the holeless region 34 and the punched region 32 can be set as appropriate by the manufacturer of the flavor inhalation article 10.
　フィルタセグメント２０の製造装置５０及び製造装置５０を用いた製造方法の一例は後述する。 An example of a manufacturing device 50 for the filter segment 20 and a manufacturing method using the manufacturing device 50 will be described later.
　シート材３０の１つのセグメントＳは、フィルタセグメント２０のフィルタ材２２を形成する。シート材３０の１つのセグメントＳは、打ち抜き領域３２とホールレス領域３４とが隣接して配置される方向にフィルタセグメント２０のロッドの長手方向が沿うように、例えば、シート材の幅方向（Ｙ軸方向）にギャザー加工、折り畳み加工等のクレープ処理（捲縮加工）が行われ、フィルタ材２２で円柱状のロッドが形成される。すなわち、Ｘ軸方向に沿う多数の筋が形成され、これら筋が山折り及び谷折りされることによりシート材３０の１つのセグメントＳの幅方向の幅は小さくなり、１つのセグメントＳの長手方向の長さを維持して、フィルタ材２２で円柱状のロッドが形成される。そして、円柱状のフィルタ材２２の外周をラッパー２４で巻装することによってフィルタセグメント２０が円柱状のロッド又はロッドセグメントとして形成される。 One segment S of the sheet material 30 forms the filter material 22 of the filter segment 20. One segment S of the sheet material 30 is creped (shrinked) such as gathered and folded in the width direction (Y-axis direction) of the sheet material so that the longitudinal direction of the rod of the filter segment 20 is aligned with the direction in which the punched area 32 and the holeless area 34 are adjacently arranged, and a cylindrical rod is formed from the filter material 22. That is, a large number of streaks are formed along the X-axis direction, and the width of one segment S of the sheet material 30 in the width direction is reduced by folding these streaks in the mountain and valley directions, and a cylindrical rod is formed from the filter material 22 while maintaining the longitudinal length of one segment S. Then, the filter segment 20 is formed as a cylindrical rod or rod segment by wrapping the outer periphery of the cylindrical filter material 22 with a wrapper 24.
　図３の左側図は、フィルタセグメント２０の端面として、フィルタ材２２のホールレス領域３４側を見た図であり、図３の右側図は、フィルタセグメント２０の端面として、フィルタ材２２の打ち抜き領域３２側を見た図である。図３の左側図に示すフィルタ材２２のホールレス領域３４側の端面は、図３の右側図に示すフィルタ材２２の打ち抜き領域３２側の端面に比べて、「鬆（す）」、すなわちホールが小さい。このため、フィルタセグメント２０のロッドは、軸方向に沿って、打ち抜き領域３２の方が、ホールレス領域３４に比べてフィルタ材２２の密度が低く、低通気抵抗の領域として形成される。言い換えると、フィルタセグメント２０のロッドは、軸方向に沿って、ホールレス領域３４の方が、打ち抜き領域３２に比べてフィルタ材２２の密度が高く、高通気抵抗の領域として形成される。このため、フィルタセグメント２０のロッドの軸方向に沿って打ち抜き領域３２とホールレス領域３４とが隣接して配置されることにより、比較的低通気抵抗の領域と、比較的高通気抵抗の領域とが１つのシート材３０の１つのセグメントＳのフィルタ材２２で形成される。このため、１つのフィルタ材２２によって、２つなど複数の異なる濾過性能等を有する領域をフィルタセグメント２０のロッドの軸方向に沿って形成しながら、シート材３０の外周を１つのラッパー２４で巻いてフィルタセグメント２０のロッドの形状を維持することができる。このため、フィルタセグメント２０のロッドの形成時に、濾過性能が異なる領域を形成するために２つなど、それぞれ巻取紙で巻いた複数のフィルタセグメントを接続することを省略でき、さらに複数のフィルタセグメントの外周をラッパー（巻取紙）で巻くといった製造作業を省略することができる。 3 is a view of the holeless region 34 of the filter material 22 as the end face of the filter segment 20, and the right side of FIG. 3 is a view of the punched region 32 of the filter material 22 as the end face of the filter segment 20. The end face of the filter material 22 on the holeless region 34 side shown in the left side of FIG. 3 is "loose", i.e., has smaller holes, than the end face of the filter material 22 on the punched region 32 side shown in the right side of FIG. 3. For this reason, the filter material 22 is lower in the punched region 32 along the axial direction of the rod of the filter segment 20 than in the holeless region 34, and is formed as a region of low airflow resistance. In other words, the filter material 22 is higher in the holeless region 34 along the axial direction of the rod of the filter segment 20 than in the punched region 32, and is formed as a region of high airflow resistance. Therefore, by arranging the punched area 32 and the holeless area 34 adjacently along the axial direction of the rod of the filter segment 20, an area with relatively low airflow resistance and an area with relatively high airflow resistance are formed in the filter material 22 of one segment S of one sheet material 30. Therefore, it is possible to form a plurality of areas with different filtering performance, such as two, along the axial direction of the rod of the filter segment 20 using one filter material 22, while wrapping the outer periphery of the sheet material 30 with one wrapper 24 to maintain the rod shape of the filter segment 20. Therefore, when forming the rod of the filter segment 20, it is possible to omit connecting a plurality of filter segments, each wrapped in a wrapping paper, such as two, to form areas with different filtering performance, and further omit the manufacturing work of wrapping the outer periphery of the plurality of filter segments with a wrapper (winding paper).
　そして、本実施形態では、フィルタセグメント２０は、フィルタ材２２のホールレス領域３４（図３の左側図）で香味吸引物品１０の吸口端１４ｂが形成されることが好適である。すなわち、フィルタセグメント（ロッド）２０の軸方向に沿って、打ち抜き領域３２は、ホールレス領域３４の上流側（香味生成セグメント１２側）に配置されている。このため、例えば、フィルタセグメント２０の吸口端１４ｂを含む位置に、ホールレス領域３４すなわち高濾過領域を配置し、吸口端１４ｂから香味生成セグメント１２側に対して離れた位置に打ち抜き領域３２を配置する。したがって、フィルタセグメント２０は、吸口端１４ｂ側に「鬆（す）」、すなわちホールが形成されることを少なくすることができ、ユーザが香味吸引物品１０のマウスピースセグメント１４の吸口端１４ｂを見たときの見た目を良好にすることができる。また、フィルタセグメント２０は、１つの部材（シート材３０の１つのセグメントＳのフィルタ材２２）で長手方向に沿う位置の通気抵抗を調整し、打ち抜き領域３２の存在によって低通気抵抗の領域を形成することができる。そして、本実施形態によれば、このようなフィルタセグメント２０を搭載した香味吸引物品１０を提供できる。 In this embodiment, it is preferable that the filter segment 20 has the mouth end 14b of the flavor inhalation article 10 formed in the holeless region 34 (left side view in Figure 3) of the filter material 22. That is, along the axial direction of the filter segment (rod) 20, the punched-out region 32 is arranged upstream of the holeless region 34 (flavor generating segment 12 side). For this reason, for example, the holeless region 34, i.e., the high filtration region, is arranged at a position including the mouth end 14b of the filter segment 20, and the punched-out region 32 is arranged at a position away from the mouth end 14b toward the flavor generating segment 12 side. Therefore, the filter segment 20 can be made to have less "looseness", i.e., less holes, on the mouth end 14b side, and the appearance can be improved when a user looks at the mouth end 14b of the mouthpiece segment 14 of the flavor inhalation article 10. In addition, the filter segment 20 can adjust the airflow resistance at a position along the longitudinal direction with one member (the filter material 22 of one segment S of the sheet material 30), and can form an area of low airflow resistance due to the presence of the punched area 32. According to this embodiment, a flavor inhalation article 10 equipped with such a filter segment 20 can be provided.
　フィルタセグメント２０のフィルタ材２２の通気抵抗は、シート材３０の選択に依存するだけでなく、後述する製造装置５０（図４参照）のクレープ部（捲縮部）６４の１対のクレープローラ６４ａ，６４ｂによるクレープ深さ（図５Ａ及び図５Ｂ参照）の設定等により調整される。
　第１のセグメント（打ち抜き領域）３２と第２のセグメント（ホールレス領域）３４とのフィルタセグメント２０のロッド１ｍｍあたりの通気抵抗の差は、０．５ｍｍＨ２Ｏ／ｍｍ～１０ｍｍＨ２Ｏ／ｍｍであり、好ましくは１ｍｍＨ２Ｏ／ｍｍ～５ｍｍＨ２Ｏ／ｍｍであることが好適である。 The airflow resistance of the filter material 22 of the filter segment 20 not only depends on the selection of the sheet material 30, but can also be adjusted by, for example, setting the crepe depth (see FIGS. 5A and 5B ) by a pair of crepe rollers 64 a, 64 b in the crepe section (crimping section) 64 of the manufacturing apparatus 50 (see FIG. 4 ), which will be described later.
The difference in air flow resistance per mm of the rod of the filter segment 20 between the first segment (punched region) 32 and the second segment (holeless region) 34 is 0.5 mmH 2 O/mm to 10 mmH 2 O/mm, and preferably 1 mmH 2 O/mm to 5 mmH 2 O/mm.
　ラッパー２４は、任意の巻取紙を使用可能である。フィルタセグメント２０の適宜の硬さを保つために、坪量の大きめ（厚い紙）の巻取紙を用いてもよい。ラッパー２４の坪量は３０ｇｓｍ以上、好ましくは５０ｇｓｍであることが好適であり、１００ｇｓｍ以下であることがより好適である。香味吸引物品１０のフィルタセグメント２０の硬さ維持のためには、チップペーパ１６を厚くしてもよい。 Any type of wrapping paper can be used for the wrapper 24. To maintain the appropriate hardness of the filter segment 20, wrapping paper with a larger basis weight (thick paper) may be used. The basis weight of the wrapper 24 is preferably 30 gsm or more, more preferably 50 gsm, and even more preferably 100 gsm or less. To maintain the hardness of the filter segment 20 of the flavor inhalation article 10, the tipping paper 16 may be thickened.
　以下、このようなフィルタセグメント２０の製造装置５０について図４から図８を用いて説明する。 The manufacturing device 50 for such a filter segment 20 will be described below with reference to Figures 4 to 8.
　図４には、図２に示すシート材３０と同様に、ＸＹＺ直交座標系を規定する。なお、Ｘ軸方向は、シート材３０が後述するフィード部６２から切断部５８に向かって搬送される方向である。 In FIG. 4, an XYZ Cartesian coordinate system is defined, similar to the sheet material 30 shown in FIG. 2. The X-axis direction is the direction in which the sheet material 30 is transported from the feed section 62 to the cutting section 58, which will be described later.
　図４に示すように、香味吸引物品１０用のロッドの製造装置５０は、シート材３０の供給部５２と、シート材３０の処理部５４と、ロッド形成部（ロッド巻上部）５６と、ロッド切断部５８と、ロッドの光学検査装置（検査ユニット）６０とを有する。供給部５２、処理部５４、ロッド形成部５６、ロッド切断部５８、光学検査装置６０は、図示しない制御装置により制御される。なお、製造装置５０の制御装置は、光学検査装置６０の後述する制御部６０ｃからの情報に基づいて、適宜に供給部５２、処理部５４、ロッド形成部５６、及び、ロッド切断部５８を例えばフィードバック制御を行うなど、適宜に制御することが好適である。なお、製造装置５０の制御装置は、例えば、光学検査装置６０の後述する制御部６０ｃからの情報に基づいて、供給部５２によるシート材３０の供給、処理部５４の後述するクレープ部（捲縮部）６４によるシート材３０の捲縮、後述する打ち抜き部６６によるシート材３０の打ち抜き、ロッド形成部５６によるロッドの形成、及び、ロッド切断部５８によるロッドの切断、の少なくとも１つを制御することも好適である。 As shown in FIG. 4, the manufacturing apparatus 50 for the rods for the flavor inhalation article 10 has a supply section 52 for the sheet material 30, a processing section 54 for the sheet material 30, a rod forming section (rod winding section) 56, a rod cutting section 58, and a rod optical inspection device (inspection unit) 60. The supply section 52, processing section 54, rod forming section 56, rod cutting section 58, and optical inspection device 60 are controlled by a control device (not shown). It is preferable that the control device of the manufacturing apparatus 50 appropriately controls the supply section 52, processing section 54, rod forming section 56, and rod cutting section 58, for example by feedback control, based on information from a control section 60c of the optical inspection device 60, which will be described later. In addition, it is also preferable that the control device of the manufacturing device 50 controls at least one of the following based on information from the control unit 60c of the optical inspection device 60, which will be described later: the supply of the sheet material 30 by the supply unit 52, the crimping of the sheet material 30 by the creping unit (crimping unit) 64 of the processing unit 54, which will be described later, the punching of the sheet material 30 by the punching unit 66, which will be described later, the formation of the rod by the rod forming unit 56, and the cutting of the rod by the rod cutting unit 58.
　供給部５２は、ホールレスのシート材３０、又は、予め、打ち抜き領域３２とホールレス領域３４とが形成されたシート材３０を所定方向に搬送するように供給する。供給部５２は、ボビン５２ａと、ダンサーユニット５２ｂと、補助ローラ５２ｃとを有する。 The supply unit 52 supplies and conveys the holeless sheet material 30, or the sheet material 30 on which the punched area 32 and the holeless area 34 have been formed in advance, in a predetermined direction. The supply unit 52 has a bobbin 52a, a dancer unit 52b, and an auxiliary roller 52c.
　本実施形態では、ボビン５２ａには、例えばＹ軸方向に平行なシャフト５２ａ１の軸回りに、打ち抜き領域３２（開口３３）が形成されていないホールレスのシート材３０が巻かれている。シート材３０の元の長さ（ボビン５２ａに巻かれたシート材３０の長さ）は、５０ｍから１００ｍ又はそれ以上の長さなど、適宜の長さに形成される。シート材３０はシャフト５２ａ１の回転に伴って回転するボビン（原反紙ロール）５２ａから所定方向（ダンサーユニット５２ｂ）に繰り出される。シート材３０は、例えば等速や等張力など、シート材３０の長手方向への移動が制御されながら、シート材３０の長手方向に繰り出される。 In this embodiment, the bobbin 52a has a holeless sheet material 30 with no punched area 32 (opening 33) formed therein wound around the axis of a shaft 52a1 parallel to the Y-axis direction, for example. The original length of the sheet material 30 (the length of the sheet material 30 wound around the bobbin 52a) is formed to an appropriate length, such as 50 m to 100 m or more. The sheet material 30 is unwound in a predetermined direction (dancer unit 52b) from the bobbin (raw paper roll) 52a, which rotates with the rotation of the shaft 52a1. The sheet material 30 is unwound in the longitudinal direction of the sheet material 30 while the movement of the sheet material 30 in the longitudinal direction is controlled, for example, at a constant speed and constant tension.
　ダンサーユニット５２ｂは、供給部５２のボビン５２ａの下流側であって、処理部５４の後述するフィード部６２の上流側に設けられる。ダンサーユニット５２ｂは、ボビン５２ａの径の変化、シート材３０の送り速度の変化等によるシート材３０の張力変化を少なくするように、シート材３０を調整する。ダンサーユニット５２ｂは複数の上側ローラ５２ｂ１と複数の下側ローラ５２ｂ２とを有する。シート材３０はダンサーユニット５２ｂの上下ローラ５２ｂ１，５２ｂ２間をジグザグに通される。 The dancer unit 52b is provided downstream of the bobbin 52a of the supply section 52 and upstream of the feed section 62 of the processing section 54, which will be described later. The dancer unit 52b adjusts the sheet material 30 so as to reduce changes in the tension of the sheet material 30 caused by changes in the diameter of the bobbin 52a, changes in the feed speed of the sheet material 30, etc. The dancer unit 52b has multiple upper rollers 52b1 and multiple lower rollers 52b2. The sheet material 30 is passed in a zigzag pattern between the upper and lower rollers 52b1, 52b2 of the dancer unit 52b.
　ダンサーユニット５２ｂの下流側には、補助ローラ５２ｃが設けられる。補助ローラ５２ｃは、ダンサーユニット５２ｂを通過したシート材３０の向きを後述するフィード部６２に向けて変更する。 An auxiliary roller 52c is provided downstream of the dancer unit 52b. The auxiliary roller 52c changes the direction of the sheet material 30 that has passed through the dancer unit 52b toward the feed section 62, which will be described later.
　処理部５４は、シート材３０をロッドとして形成するための予備作業を行うとともに、１つのセグメントＳにおいて通気抵抗を変化させるための領域を形成する。処理部５４は、例えば紙材製のシート材３０の流れに沿って、フィード部６２、クレープ部６４、打ち抜き部６６、補助ローラ５４ａ、添加部６８を有する。 The processing section 54 performs preliminary work to form the sheet material 30 into a rod, and also forms an area for changing the air flow resistance in one segment S. The processing section 54 has a feed section 62, a creping section 64, a punching section 66, an auxiliary roller 54a, and an addition section 68 along the flow of the sheet material 30, which is made of, for example, paper.
　フィード部６２は、シート材３０がＸ軸方向に適宜の張力を持つ状態でシート材３０を下流側に移動させる。フィード部６２は、例えば１対のフィードローラ６２ａ，６２ｂを有する。フィード部６２の上側ローラ６２ａは例えば図４中の紙面の奥行き方向である左右に並べられた２個のゴムローラで形成される。下側ローラ６２ｂは表面が平坦な例えば金属ローラで形成される。上側ローラ６２ａの２個のゴムローラの表面には螺旋が形成され、フィードローラ６２ａ，６２ｂの回転時に、シート材３０の幅方向の両端が離隔するように、横方向（Ｙ軸方向）に広げられ、この時点における不用意な皺の発生が防止される。 The feed section 62 moves the sheet material 30 downstream while the sheet material 30 has an appropriate tension in the X-axis direction. The feed section 62 has, for example, a pair of feed rollers 62a, 62b. The upper roller 62a of the feed section 62 is formed, for example, of two rubber rollers arranged side by side, that is, in the depth direction of the paper surface in FIG. 4. The lower roller 62b is formed, for example, of a metal roller with a flat surface. A spiral is formed on the surface of the two rubber rollers of the upper roller 62a, and when the feed rollers 62a, 62b rotate, the two ends of the sheet material 30 in the width direction are spread apart in the horizontal direction (Y-axis direction), preventing the occurrence of unintended wrinkles at this point.
　フィード部６２の下流側には、シート材３０にクレープ処理を施すためのクレープ部（捲縮部）６４が設けられる。クレープ部６４は、供給部５２から搬送されるシート材３０を捲縮する。クレープ部６４は、１対のクレープローラ６４ａ，６４ｂを有する。クレープローラ６４ａ，６４ｂは、フィルタセグメント２０をロッドとして形成しやすくするＸ軸方向に沿う縦皺をシート材３０に形成するために利用される。すなわち、クレープ部６４は、シート材３０をロッドにする際にシート材３０を折り込みやすくするために、長手方向に沿う筋状の癖付けをする。 A creping section (crimping section) 64 is provided downstream of the feed section 62 for creping the sheet material 30. The creping section 64 crimps the sheet material 30 conveyed from the supply section 52. The creping section 64 has a pair of creping rollers 64a, 64b. The creping rollers 64a, 64b are used to form vertical wrinkles in the sheet material 30 along the X-axis direction, which makes it easier to form the filter segments 20 into rods. In other words, the creping section 64 creates streaky crimps along the longitudinal direction of the sheet material 30, making it easier to fold the sheet material 30 when forming it into a rod.
　図５Ａ及び図５Ｂに示すように、１対のクレープローラ６４ａ，６４ｂは、互いにＹ軸方向に平行な回転軸６４１１，６４２１と、複数の凸部（円盤状部材）６４１２，６４２２とを有する。上側の回転軸６４１１を第１の回転軸とし、下側の回転軸６４２１を第２の回転軸とする。第１の回転軸６４１１には、複数の第１の凸部６４１２が設けられ、第２の回転軸６４２１には、複数の第２の凸部６４２２が設けられる。複数の凸部６４１２，６４２２は、それぞれ、同一径の円板状部材として形成されていることが好適である。なお、隣接する凸部６４１２，６４２２同士は、シート材３０の幅方向（Ｙ軸方向）に例えば所定間隔に離間する。 As shown in Figures 5A and 5B, a pair of crepe rollers 64a, 64b have rotating shafts 6411, 6421 parallel to each other in the Y-axis direction, and multiple convex portions (disk-shaped members) 6412, 6422. The upper rotating shaft 6411 is the first rotating shaft, and the lower rotating shaft 6421 is the second rotating shaft. The first rotating shaft 6411 is provided with multiple first convex portions 6412, and the second rotating shaft 6421 is provided with multiple second convex portions 6422. It is preferable that the multiple convex portions 6412, 6422 are each formed as a disk-shaped member of the same diameter. Adjacent convex portions 6412, 6422 are spaced apart, for example, at a predetermined interval in the width direction (Y-axis direction) of the sheet material 30.
　第１の回転軸６４１１及び第２の回転軸６４２１は互いにシート材３０の幅方向（Ｙ軸方向）に平行な状態を維持しながら、相対的に近接及び離隔可能である。第１の回転軸６４１１に対する複数の第１の凸部６４１２の突出量は、略同一である。複数の第１の凸部６４１２は、幅方向に所定間隔に離間する。第２の回転軸６４２１に対する複数の第２の凸部６４２２の突出量は、略同一である。複数の第２の凸部６４２２は、幅方向に所定間隔に離間する。第１の回転軸６４１１と第２の回転軸６４２１とを近接させたとき、第１の凸部６４１２と第２の凸部６４２２とはそれぞれ離間した位置にある。第１の回転軸６４１１及び第２の回転軸６４２１の近接及び離隔方向に沿って、第１の凸部６４１２の頂部６４１２ａと第２の凸部６４２２の頂部６４２２ａとの間の距離（図５Ａ中の符号Ｄ１及び図５Ｂ中の符号Ｄ２）を噛み合い量とする。距離Ｄ１，Ｄ２は、例えば１ｍｍ程度、又は、それ以下とすることが好適である。クレープ部６４の噛み合い量（距離Ｄ１，Ｄ２）を調整することで、後述するロッド形成部５６においてフィルタセグメント２０のロッドを形成するときの紙製のシート材３０のクレープ深さを調整することができる。クレープ深さは、一対のクレープローラ６４ａ，６４ｂの凸部６４１２，６４２２の頂部６４１２ａ，６４２２ａ同士のＺ軸方向の距離に置き換えることができる。図５Ａの距離Ｄ１と、図５Ｂの距離Ｄ２とを比較すると、距離Ｄ２の方が大きい。このとき、シート材３０のクレープ深さは、図５Ｂに示す例の方が、図５Ａに示す例よりも大きくなる。シート材３０をクレープ処理中、クレープ部６４の第１の回転軸６４１１と第２の回転軸６４２１との間隔は、位置関係が固定されている。 The first rotating shaft 6411 and the second rotating shaft 6421 can be moved closer to or farther away from each other while maintaining a parallel state in the width direction (Y-axis direction) of the sheet material 30. The multiple first convex portions 6412 protrude from the first rotating shaft 6411 by approximately the same amount. The multiple first convex portions 6412 are spaced apart at a predetermined interval in the width direction. The multiple second convex portions 6422 protrude from the second rotating shaft 6421 by approximately the same amount. The multiple second convex portions 6422 are spaced apart at a predetermined interval in the width direction. When the first rotating shaft 6411 and the second rotating shaft 6421 are brought close to each other, the first convex portions 6412 and the second convex portions 6422 are in spaced apart positions. The distance between the top 6412a of the first convex portion 6412 and the top 6422a of the second convex portion 6422 along the approach and separation direction of the first rotation shaft 6411 and the second rotation shaft 6421 (symbol D1 in FIG. 5A and symbol D2 in FIG. 5B) is defined as the meshing amount. The distances D1 and D2 are preferably set to, for example, about 1 mm or less. By adjusting the meshing amount (distances D1 and D2) of the crepe portion 64, it is possible to adjust the crepe depth of the paper sheet material 30 when forming the rod of the filter segment 20 in the rod forming section 56 described later. The crepe depth can be replaced with the distance in the Z-axis direction between the tops 6412a and 6422a of the convex portions 6412 and 6422 of the pair of crepe rollers 64a and 64b. Comparing the distance D1 in FIG. 5A with the distance D2 in FIG. 5B, the distance D2 is larger. At this time, the crepe depth of the sheet material 30 is greater in the example shown in FIG. 5B than in the example shown in FIG. 5A. During the creping process of the sheet material 30, the positional relationship between the first rotating shaft 6411 and the second rotating shaft 6421 of the creping unit 64 is fixed.
　したがって、図５Ａ及び図５Ｂに示す回転軸６４１１，６４２１の位置関係を調整すると、凸部６４１２，６４２２同士の噛合い深さ（距離Ｄ１、Ｄ２）が調整され、シート材３０に形成されるＸ軸方向に沿う縦皺の深さ、或いは、シート材３０の延伸の程度が変化する。そして、凸部６４１２，６４２２同士の噛合い深さを調整することにより、フィルタ材２２の１つのセグメントＳにおける通気抵抗を調整することができる。 Therefore, by adjusting the positional relationship of the rotation axes 6411, 6421 shown in Figures 5A and 5B, the meshing depth (distances D1, D2) between the protrusions 6412, 6422 is adjusted, and the depth of the vertical wrinkles along the X-axis direction formed in the sheet material 30 or the degree of stretching of the sheet material 30 changes. By adjusting the meshing depth between the protrusions 6412, 6422, the airflow resistance in one segment S of the filter material 22 can be adjusted.
　なお、１対のクレープローラ６４ａ，６４ｂは、シート材３０が第１の凸部６４１２の頂部６４１２ａと第２の凸部６４２２の頂部６４２２ａとの間を滑って下流側に移動するのであれば、回転軸６４１１，６４２１の軸回りに回転させなくてもよい。このため、クレープ部６４の１対のクレープローラ６４ａ，６４ｂは、それぞれクレープ器具として形成されていればよい。 Note that the pair of crepe rollers 64a, 64b do not need to rotate around the rotation shafts 6411, 6421 as long as the sheet material 30 slides between the apex 6412a of the first convex portion 6412 and the apex 6422a of the second convex portion 6422 and moves downstream. For this reason, the pair of crepe rollers 64a, 64b of the crepe section 64 may each be formed as a crepe tool.
　図４に示すように、クレープ部６４の下流側には、打ち抜き部６６が配設される。打ち抜き部６６は、供給部５２から搬送（供給）されるシート材３０の一部を打ち抜く。打ち抜き部６６は、シート材３０の一部を打ち抜き、複数の開口３３を形成することで、打ち抜き領域３２とホールレス領域３４とを形成する。本実施形態では、打ち抜き部６６は、シート材３０の搬送方向に沿って、クレープ部６４の下流側に配設されるものとして説明する。打ち抜き部６６は、クレープ部６４の上流側に配設されることも好適である。打ち抜き部６６とクレープ部６４との位置関係は、どちらが上流側、下流側でも良いが、クレープ部６４が上流側で、打ち抜き部６６が下流側の方が望ましいシート材３０がクレープ部６４を通ると、シート材３０が伸びる。このため、シート材３０が伸びた後に打ち抜き部６６でシート材３０を打ち抜くことで、打ち抜き位置の制御が行いやすい。一方、打ち抜き部６６がクレープ部６４の上流に配置される場合、搬送中のシート材３０に十分にテンションがかかっているため、開口３３を打ち抜きやすい。 As shown in FIG. 4, a punching section 66 is disposed downstream of the creping section 64. The punching section 66 punches out a portion of the sheet material 30 transported (supplied) from the supply section 52. The punching section 66 punches out a portion of the sheet material 30 to form a plurality of openings 33, thereby forming a punched region 32 and a holeless region 34. In this embodiment, the punching section 66 is described as being disposed downstream of the creping section 64 along the transport direction of the sheet material 30. It is also preferable that the punching section 66 is disposed upstream of the creping section 64. The positional relationship between the punching section 66 and the creping section 64 may be either the upstream side or the downstream side, but it is preferable that the creping section 64 is upstream and the punching section 66 is downstream. When the sheet material 30 passes through the creping section 64, the sheet material 30 stretches. For this reason, by punching the sheet material 30 with the punching section 66 after the sheet material 30 has been stretched, it is easy to control the punching position. On the other hand, if the punching section 66 is located upstream of the creping section 64, sufficient tension is applied to the sheet material 30 during transport, making it easy to punch the openings 33.
　打ち抜き部６６は、例えば、上部ローラ（第１ローラ）６６ａと、下部ローラ（第２ローラ）６６ｂとを有する。打ち抜き部６６は、上下ローラ６６ａ，６６ｂ間をシート材３０が通る際に、シート材３０に所定の大きさの所定形状の複数の開口３３を形成する。すなわち、ホールレスのシート材３０に所定の大きさの所定形状の複数の開口３３を形成することにより、打ち抜き領域３２とホールレス領域３４とを有するシート材３０（図２参照）が形成される。 The punching unit 66 has, for example, an upper roller (first roller) 66a and a lower roller (second roller) 66b. The punching unit 66 forms a plurality of openings 33 of a predetermined size and shape in the sheet material 30 as the sheet material 30 passes between the upper and lower rollers 66a, 66b. In other words, by forming a plurality of openings 33 of a predetermined size and shape in the holeless sheet material 30, a sheet material 30 (see FIG. 2) having a punched area 32 and a holeless area 34 is formed.
　上部ローラ６６ａは、シート材３０を適宜にカットする刃（図６Ｃ参照）を有する。下部ローラ６６ｂは、例えば凹凸がない金属ロールとして形成される。例えばフィード部６２によってシート材３０の搬送速度を制御しながら、これら上部ローラ６６ａ及び下部ローラ６６ｂの間にシート材３０を搬送し、挟持される際に、刃でシート材３０を打ち抜いて、所定の開口３３を順次形成する。すなわち、シート材３０に、打ち抜き領域３２及びホールレス領域３４の組（セグメントＳ）を繰り返し形成する。 The upper roller 66a has a blade (see FIG. 6C) that appropriately cuts the sheet material 30. The lower roller 66b is formed, for example, as a metal roll with no irregularities. For example, while the conveying speed of the sheet material 30 is controlled by the feed section 62, the sheet material 30 is conveyed between the upper roller 66a and the lower roller 66b, and as it is clamped, the blade punches out the sheet material 30 to sequentially form predetermined openings 33. In other words, sets (segments S) of punched areas 32 and holeless areas 34 are repeatedly formed in the sheet material 30.
　刃は、打ち抜いた紙片に角部がない状態に打ち抜くように形成される。すなわち、刃は、環状で、角部がない形状に開口３３を打ち抜いて形成する形状に形成される。このため、打ち抜き部６６の刃は、打ち抜いた紙片がシート材３０に連結されたままとなることを防止する。 The blade is formed so that the punched piece of paper has no corners. That is, the blade is formed so that it punches out the opening 33 in a circular shape without corners. Therefore, the blade of the punching portion 66 prevents the punched piece of paper from remaining connected to the sheet material 30.
　ここでは、打ち抜き部６６として、２つの例を説明する。図６Ａには、第１の例（フレキシブルダイ６６ｃを使用する方式）を示す。図７には第２の例（ロータリーダイを使用する方式）を示す。 Here, two examples of the punching section 66 will be described. Figure 6A shows the first example (a method using a flexible die 66c). Figure 7 shows the second example (a method using a rotary die).
　図６Ａに示す打ち抜き部６６は、フレキシブルダイ６６ｃ（図６Ｂ参照）が磁着される、例えば金属材製の上部ローラ（打ち抜きローラ）６６ａと、下部ローラ（アンビルローラ）６６ｂとを有する。
　図６Ｃに示すように、フレキシブルダイ６６ｃは、例えば０．４５ｍｍ程度の薄い金属シートにエッチングまたは削り出し加工を施し、金属シートの表面に、開口３３を打ち抜くため、開口３３の形状に形成されたカット刃６６ｄが設けられている。シート材３０の開口３３を打ち抜く際はフレキシブルダイ６６ｃを磁性の上部ローラ６６ａに磁着させる。通常、２枚のフレキシブルダイ６６ｃを上部ローラ６６ａに張り付ける。例えば２枚のフレキシブルダイ６６ｃを上部ローラ６６ａの周方向又は軸方向に隣接させて使用する。そして、上部ローラ６６ａ全体をフレキシブルダイ６６ｃでカバーする。ここでは、打ち抜き領域３２及びホールレス領域３４が、シート材３０の長手方向に沿って同一形状に繰り返し形成されるように、上部ローラ６６ａに対してフレキシブルダイ６６ｃがセットされればよい。 The punching section 66 shown in FIG. 6A has an upper roller (punching roller) 66a made of, for example, a metal material to which a flexible die 66c (see FIG. 6B) is magnetically attached, and a lower roller (anvil roller) 66b.
As shown in FIG. 6C, the flexible die 66c is formed by etching or machining a thin metal sheet, for example, about 0.45 mm, and a cutting blade 66d formed in the shape of the opening 33 is provided on the surface of the metal sheet to punch the opening 33. When punching the opening 33 in the sheet material 30, the flexible die 66c is magnetically attached to the magnetic upper roller 66a. Usually, two flexible dies 66c are attached to the upper roller 66a. For example, two flexible dies 66c are used adjacent to each other in the circumferential or axial direction of the upper roller 66a. Then, the entire upper roller 66a is covered with the flexible die 66c. Here, the flexible die 66c may be set relative to the upper roller 66a so that the punching area 32 and the holeless area 34 are repeatedly formed in the same shape along the longitudinal direction of the sheet material 30.
　図６Ａに示すように、下部ローラ（アンビルロール）６６ｂには、打ち抜き部６６で部分的に打ち抜かれたシート材３０の打ち抜き片を除去する打ち抜き片除去部として、吸引部（吸引源）６７と連通する多数の孔６６ｅが形成されることが好適である。すなわち、多数の孔（打ち抜き片除去部）６６ｅは、打ち抜き部６６内に設けられる。これらの孔６６ｅは、打ち抜きたい開口３３の形状に合わせて配置されることが好適である。すなわち、上部ローラ６６ａの最下面近傍と下部ローラ６６ｂの最上面近傍とが対向するとき、開口３３の形状に形成されたフレキシブルダイ６６ｃのカット刃と、下部ローラ６６ｂの孔６６ｅの周囲とが、シート材３０を挟んで、シート材３０に開口３３を形成するとともに、打ち抜いた開口３３の形状の紙片が孔６６ｅの周囲に吸着される。そして、孔６６ｅの周囲に吸着された開口３３の形状の紙片は、下部ローラ（アンビルロール）６６ｂの下方に移動させたときに紙片への吸着を解除することで、所定の場所で下部ローラ６６ｂから脱落し、打ち抜き片除去部としてのトレイ（図示せず）等に集められる。 As shown in FIG. 6A, the lower roller (anvil roll) 66b is preferably formed with a number of holes 66e communicating with the suction section (suction source) 67 as a punched piece removal section that removes punched pieces of the sheet material 30 that have been partially punched out by the punching section 66. That is, the numerous holes (punched piece removal section) 66e are provided within the punching section 66. These holes 66e are preferably arranged according to the shape of the opening 33 to be punched out. That is, when the vicinity of the bottom surface of the upper roller 66a faces the vicinity of the top surface of the lower roller 66b, the cutting blade of the flexible die 66c, which is formed in the shape of the opening 33, and the periphery of the hole 66e of the lower roller 66b sandwich the sheet material 30 to form the opening 33 in the sheet material 30, and the paper piece in the shape of the punched opening 33 is adsorbed around the hole 66e. The piece of paper in the shape of the opening 33 that is attracted to the periphery of the hole 66e is released from the attraction when it is moved below the lower roller (anvil roll) 66b, so that it falls off the lower roller 66b at a predetermined location and is collected in a tray (not shown) or the like that serves as a punched piece removal section.
　図６Ａに示す上部ローラ６６ａ及びフレキシブルダイ６６ｃを用いる場合、図７に示すロータリーダイとしての上部ローラ６６ａを用いるよりも安価に形成され得る。図６Ａに示すフレキシブルダイ６６ｃを用いる場合、比較的厚い材料を打ち抜くことが難しいとされる。材質にもよるが、例えば０．５ｍｍ以上の厚さのシート材３０はうまく打ち抜きができないことがあり、フレキシブルダイ６６ｃのカット刃から打ち抜いた紙片が脱離しない可能性が生じる。 When using the upper roller 66a and flexible die 66c shown in FIG. 6A, it can be manufactured more cheaply than when using the upper roller 66a as a rotary die shown in FIG. 7. When using the flexible die 66c shown in FIG. 6A, it is said to be difficult to punch out relatively thick materials. Although it depends on the material, for example, sheet material 30 with a thickness of 0.5 mm or more may not be punched out well, and there is a possibility that the punched paper pieces will not come off the cutting blade of the flexible die 66c.
　図７に示す例では、上部ローラ６６ａは、ロータリーダイとして形成される。上部ローラ（ロータリーダイ）６６ａは、例えば金属ロールを削り出すことにより、シート材３０に開口３３を形成するための所定のカット刃６６ｆが形成される。一般に、上部ローラ６６ａは、比較的厚いシート材３０に対して用いることができる、とされる。カット刃６６ｆの切れ味が悪くなると、カット刃６６ｆに対して再研磨を実施することで上部ローラ（ロータリーダイ）６６ａを再度使用可能である。 In the example shown in FIG. 7, the upper roller 66a is formed as a rotary die. The upper roller (rotary die) 66a is formed with a predetermined cutting blade 66f for forming the opening 33 in the sheet material 30, for example, by cutting out a metal roll. In general, the upper roller 66a can be used for relatively thick sheet material 30. When the cutting blade 66f becomes dull, the upper roller (rotary die) 66a can be reused by re-grinding the cutting blade 66f.
　図７に示す例では、上部ローラ（ロータリーダイ）６６ａのカット刃６６ｆの内側には、打ち抜き片除去部として、打ち抜いた紙片と同程度又はそれよりも僅かに小さい大きさの孔６６ｇが形成される。それらの孔６６ｇは、吸引部（吸引源）６７に連通する。すなわち、上部ローラ６６ａの最下面近傍と下部ローラ６６ｂの最上面近傍とが対向するとき、開口３３の形状に形成されたカット刃６６ｆと、下部ローラ６６ｂとが、シート材３０を挟んで、シート材３０に開口３３を形成するとともに、打ち抜いた開口３３の形状の紙片が孔６６ｇを通して上部ローラ（ロータリーダイ）６６ａ内に集められる。集められた紙片は、上部ローラ６６ａ及び下部ローラ６６ｂの回転の停止後、例えば上部ローラ６６ａの例えば回転軸に沿って取り除かれる。または、上部ローラ（ロータリーダイ）６６ａ内に打ち抜いた紙片を集める代わりに、孔６６ｇと吸引部（吸引源）６７の連通路の間に、吸引による空気流から紙片を分離する分離部を設けてもよい。または、図６Ａに示す下部ローラ（アンビルロール）６６ｂに形成された孔６６ｅと同様に、図７に示す下部ローラ（アンビルロール）６６ｂにも、吸引部６７に連通する孔６６ｅ（打ち抜き片除去部）を設けてもよい。この場合、孔６６ｅの周囲に吸着された開口３３の形状の紙片は、下部ローラ（アンビルロール）６６ｂの下方に移動させたときに紙片への吸着を解除することで、所定の場所で下部ローラ６６ｂから脱落し、打ち抜き片除去部としてのトレイ（図示せず）等に集められる。 In the example shown in FIG. 7, holes 66g of the same size as or slightly smaller than the punched pieces of paper are formed inside the cutter blade 66f of the upper roller (rotary die) 66a as a punched piece removal section. These holes 66g are connected to the suction section (suction source) 67. That is, when the vicinity of the bottom surface of the upper roller 66a faces the vicinity of the top surface of the lower roller 66b, the cutter blade 66f formed in the shape of the opening 33 and the lower roller 66b sandwich the sheet material 30 to form the opening 33 in the sheet material 30, and the punched pieces of paper in the shape of the opening 33 are collected in the upper roller (rotary die) 66a through the holes 66g. After the rotation of the upper roller 66a and the lower roller 66b stops, the collected pieces of paper are removed, for example, along the rotation axis of the upper roller 66a. Alternatively, instead of collecting the punched pieces of paper in the upper roller (rotary die) 66a, a separation section that separates the pieces of paper from the air flow caused by suction may be provided between the hole 66g and the communication path of the suction section (suction source) 67. Alternatively, similar to the hole 66e formed in the lower roller (anvil roll) 66b shown in FIG. 6A, the lower roller (anvil roll) 66b shown in FIG. 7 may also be provided with a hole 66e (punched piece removal section) that communicates with the suction section 67. In this case, the paper pieces in the shape of the opening 33 that are adsorbed around the hole 66e are released from adsorption to the paper pieces when they are moved below the lower roller (anvil roll) 66b, so that they fall off the lower roller 66b at a predetermined location and are collected in a tray (not shown) or the like that serves as a punched piece removal section.
　なお、このような打ち抜き部６６に対して下流側に、打ち抜き片除去部として吸引部（吸引源）６７をさらに設置し、紙片を回収してもよい。そうすると、シート材３０に付着する打ち抜き紙片がより確実に除去される。この場合、例えばシート材３０の上部から圧空気を噴射し、シート材３０の下部で吸引を行って紙片を回収すればよい。 Furthermore, a suction section (suction source) 67 may be installed downstream of the punching section 66 as a punched piece removal section to collect the paper pieces. In this case, punched paper pieces adhering to the sheet material 30 can be more reliably removed. In this case, for example, compressed air may be sprayed from the top of the sheet material 30, and suction may be performed at the bottom of the sheet material 30 to collect the paper pieces.
　図４に示すように、本実施形態では、打ち抜き部６６の下流側には、添加部６８が配設される。本実施形態では、添加部６８は、液体添加部６８ａと、顆粒添加部６８ｂとを有する。添加部６８は、シート材３０のフィルタ材２２を例えばクレープ処理し、円柱状のロッドとして形成する際に、フィルタ材２２に添加剤を添加してもよい。添加剤としては、液体を添加してもよく、顆粒（固体）を添加してもよく、両方を添加してもよい。なお、本実施形態では、添加部６８を使用しないものとする。このため、添加部６８の液体添加部６８ａ及び顆粒添加部６８ｂをシート材３０が素通りするものとする。添加部６８については第２実施形態（図１５Ａ－１６Ｂ参照）において説明する。 As shown in FIG. 4, in this embodiment, an addition section 68 is disposed downstream of the punching section 66. In this embodiment, the addition section 68 has a liquid addition section 68a and a granule addition section 68b. The addition section 68 may add an additive to the filter material 22 when the filter material 22 of the sheet material 30 is creped, for example, to form it into a cylindrical rod. The additive may be a liquid, granules (solid), or both. Note that the addition section 68 is not used in this embodiment. For this reason, the sheet material 30 passes directly through the liquid addition section 68a and granule addition section 68b of the addition section 68. The addition section 68 will be described in the second embodiment (see FIGS. 15A-16B).
　添加部６８の下流側には、ロッド形成部５６が配設される。すなわち、ロッド形成部５６は、打ち抜き部６６及びクレープ部６４の下流側に設けられる。ロッド形成部５６は、シート材３０を、断面が略円形、すなわち外観が略円柱状で、軸方向に沿って打ち抜き領域３２とホールレス領域３４とが交互に配置されるロッドとして形成する。ロッド形成部５６は、巻取紙供給機構７２と、集束ガイド７４と、ラップ糊ガン７６と、トング７８とを有する。 The rod forming section 56 is disposed downstream of the adding section 68. That is, the rod forming section 56 is disposed downstream of the punching section 66 and the creping section 64. The rod forming section 56 forms the sheet material 30 into a rod having a substantially circular cross section, i.e., a substantially cylindrical appearance, in which punched regions 32 and holeless regions 34 are alternately arranged along the axial direction. The rod forming section 56 has a roll paper supply mechanism 72, a focusing guide 74, a wrap glue gun 76, and tongs 78.
　巻取紙供給機構７２は、シート状部材２４ａが巻かれたボビン７２ａから供給されるシート状部材２４ａを、シート材３０とともに集束ガイド７４に供給する。なお、シート状部材２４ａは、フィルタセグメント２０を形成するときにフィルタ材２２を巻装するラッパー２４となる。 The roll paper supply mechanism 72 supplies the sheet-like member 24a, which is supplied from a bobbin 72a around which the sheet-like member 24a is wound, to the focusing guide 74 together with the sheet material 30. The sheet-like member 24a becomes the wrapper 24 around which the filter material 22 is wound when the filter segment 20 is formed.
　集束ガイド７４は、上流から下流側に向かうにつれて、通過路径が狭くなるように形成れる。集束ガイド７４は、シート材３０が集束ガイド７４を通るにしたがって、円柱状のロッドに近づける。集束ガイド７４は、上流から下流側に向かうにつれてシート材３０が通る幅を狭くしながら、クレープ部６４で形成した縦皺（筋状の癖）にしたがってシート材３０を略蛇腹状に変形させる。これにより、シート材３０が規則的に絞り込まれ、シート材３０の形状が円柱状のロッドに近づく。集束ガイド７４は、上流から下流側に向かうにつれて、シート状部材２４ａで、ロッドに近づけたシート材３０の外周を巻装する。すなわち、集束ガイド７４は、絞り込まれたシート材３０（フィルタ材２２）の外周をラッパー２４となるシート状部材２４ａで囲いながら、円柱状のロッド状に近づける。 The focusing guide 74 is formed so that the diameter of the passage narrows from the upstream to the downstream side. The focusing guide 74 brings the sheet material 30 closer to a cylindrical rod as it passes through the focusing guide 74. The focusing guide 74 narrows the width through which the sheet material 30 passes from the upstream to the downstream side, and deforms the sheet material 30 into an approximately bellows shape according to the vertical wrinkles (striated tendencies) formed by the crepe section 64. As a result, the sheet material 30 is regularly narrowed, and the shape of the sheet material 30 approaches a cylindrical rod. As it moves from the upstream to the downstream side, the focusing guide 74 wraps the outer periphery of the sheet material 30 that has been brought closer to the rod with the sheet-like member 24a. In other words, the focusing guide 74 brings the narrowed sheet material 30 (filter material 22) closer to a cylindrical rod shape while surrounding the outer periphery with the sheet-like member 24a that becomes the wrapper 24.
　そして、集束ガイド７４を通過したシート状部材２４ａの幅方向の端面には、ラップ糊ガン７６から糊が塗布される。 Then, glue is applied from a wrap glue gun 76 to the widthwise end surface of the sheet-like member 24a that has passed through the focusing guide 74.
　そして、ラップ糊ガン７６の下流側には、トング７８が設けられる。トング７８は、ラッパー２４となるシート状部材２４ａの端面同士を接合する。このため、トング７８により、フィルタセグメント２０として形成され得るフィルタアセンブリ１８の形状が保持される。すなわち、製造装置５０のロッド形成部５６は、シート材３０をラッパー２４となるシート状部材２４ａでフィルタアセンブリ（ロッドアセンブリ）として巻上げることができる。 Tongs 78 are provided downstream of the wrap glue gun 76. The tongs 78 join the end faces of the sheet-like member 24a that will become the wrapper 24. Therefore, the tongs 78 maintain the shape of the filter assembly 18 that can be formed into the filter segment 20. In other words, the rod forming section 56 of the manufacturing device 50 can wind up the sheet material 30 with the sheet-like member 24a that will become the wrapper 24 as a filter assembly (rod assembly).
　そして、切断部５８は、トング７８で巻上げた連続したロッドを、順次所定の長さに切断する。このとき、切断部５８は、打ち抜き領域３２とホールレス領域３４とを少なくともそれぞれ１つ有する状態にロッドを切断する。このため、製造装置５０は、所定長さのフィルタアセンブリ１８を製造することができる。なお、本実施形態では、切断部５８は、例えばフィルタセグメント２０の４倍又は６倍の長さなどの所定長さのフィルタアセンブリ１８を製造する例について説明するが、フィルタアセンブリ１８を製造せずに、トング７８で巻上げた連続したロッド状部材から、直接的に、フィルタセグメント２０を製造してもよい。 Then, the cutting unit 58 sequentially cuts the continuous rod wound up by the tongs 78 to a predetermined length. At this time, the cutting unit 58 cuts the rod into a state having at least one punched region 32 and one holeless region 34. Therefore, the manufacturing device 50 can manufacture a filter assembly 18 of a predetermined length. Note that in this embodiment, an example is described in which the cutting unit 58 manufactures a filter assembly 18 of a predetermined length, such as four or six times the length of the filter segment 20, but the filter segment 20 may be manufactured directly from the continuous rod-shaped member wound up by the tongs 78 without manufacturing the filter assembly 18.
　切断部５８の下流側には、フィルタアセンブリ１８のロッドの光学検査装置６０が設けられる。 An optical inspection device 60 for the rod of the filter assembly 18 is provided downstream of the cutting section 58.
　図４及び図８に示すように、光学検査装置６０は、発光部６０ａと、発光部６０ａから照射され、フィルタアセンブリ（ロッド）１８を通過する光を受光する受光部６０ｂと、発光部６０ａ及び受光部６０ｂを制御する制御部６０ｃとを有する。 As shown in Figures 4 and 8, the optical inspection device 60 has a light-emitting unit 60a, a light-receiving unit 60b that receives light irradiated from the light-emitting unit 60a and passing through the filter assembly (rod) 18, and a control unit 60c that controls the light-emitting unit 60a and the light-receiving unit 60b.
　発光部６０ａは、例えばＬＥＤ光源などの光源である。受光部６０ｂは、カメラの撮像素子や、フォトダイオードなどの光を検知するディテクターなどである。 The light-emitting unit 60a is a light source such as an LED light source. The light-receiving unit 60b is a detector that detects light, such as an imaging element of a camera or a photodiode.
　制御部６０ｃは、コンピュータであって、物理的には、ＲＡＭ、ＲＯＭ等のメモリ、ＣＰＵ等のプロセッサ（演算回路）、通信インターフェース、ハードディスク等の情報格納部を備える。制御部６０ｃとしては、例えばパーソナルコンピュータ、クラウドサーバ、タブレット端末などが挙げられる。制御部６０ｃは、メモリに格納されるプログラムをプロセッサで実行することにより機能する。 The control unit 60c is a computer, and physically includes memories such as RAM and ROM, a processor (arithmetic circuit) such as a CPU, a communications interface, and an information storage unit such as a hard disk. Examples of the control unit 60c include a personal computer, a cloud server, and a tablet terminal. The control unit 60c functions by executing a program stored in the memory with the processor.
　受光部６０ｂとしてカメラを用いる場合、制御部６０ｃは、受光部６０ｂで受光した光情報（受光情報）に基づいて、例えば各画素における画素値（光強度）を出力する。図９に示すように、フィルタアセンブリ１８は、長手方向に沿って、シート材３０を打ち抜いた打ち抜き領域３２と打ち抜いていないホールレス領域３４でシート材３０の量が異なるため、透過光強度に差が生じる。すなわち、各フィルタアセンブリ１８は、第１の光透過部１８ａと、第１の光透過部１８ａに比べて光透過性が低い第２の光透過部１８ｂとが繰り返されている。第１の光透過部１８ａは、打ち抜き領域３２に対応し、第２の光透過部１８ｂは、ホールレス領域３４に対応する。このため、制御部６０ｃは、発光部６０ａからフィルタアセンブリ１８を通して受光部６０ｂで受光する光の強度（受光情報）に基づいて、フィルタアセンブリ１８における、フィルタ材２２の打ち抜き領域３２とホールレス領域３４との境界を認識することができる。このような透過光強度を検査する光学検査装置６０にてフィルタアセンブリ１８を検査することができる。したがって、制御部６０ｃは、フィルタアセンブリ１８の一端と他端との間における第１の光透過部１８ａ（打ち抜き領域３２）の位置及び長さ、並びに、第２の光透過部１８ｂ（ホールレス領域３４）の位置及び長さを出力することができる。制御部６０ｃは、複数の打ち抜き領域３２及び複数のホールレス領域３４が、それぞれ予め設定した所望の長さに設定されているか否かを出力する。制御部６０ｃが、複数の打ち抜き領域３２及び複数のホールレス領域３４を、それぞれ予め設定した所望の長さとして検出したのであれば、例えば、製造装置５０の制御装置は、製造装置５０の各装置（供給部５２、処理部５４、ロッド形成部５６、ロッド切断部５８等）の制御状態を維持するように制御（フィードバック制御）する。一方、制御部６０ｃが、複数の打ち抜き領域３２及び複数のホールレス領域３４を、それぞれ予め設定した所望の長さから外れているものとして検出したのであれば、製造装置５０の制御装置は、製造装置５０の各装置の制御状態を、複数の打ち抜き領域３２及び複数のホールレス領域３４がそれぞれ予め設定した所望の長さとなるように制御（フィードバック制御）する。このため、制御部６０ｃは、受光部６０ｂから制御部６０ｃに送られる信号に基づいて、シート材３０の供給部５２によるシート材３０の供給や、打ち抜き部６６によるシート材３０の打ち抜きを制御する。 When a camera is used as the light receiving unit 60b, the control unit 60c outputs, for example, a pixel value (light intensity) for each pixel based on the light information (light receiving information) received by the light receiving unit 60b. As shown in FIG. 9, the filter assembly 18 has a different amount of sheet material 30 along the longitudinal direction in the punched area 32 where the sheet material 30 is punched and in the holeless area 34 where the sheet material 30 is not punched, resulting in a difference in transmitted light intensity. That is, each filter assembly 18 has a first light transmitting portion 18a and a second light transmitting portion 18b having a lower light transmittance than the first light transmitting portion 18a repeated. The first light transmitting portion 18a corresponds to the punched area 32, and the second light transmitting portion 18b corresponds to the holeless area 34. Therefore, the control unit 60c can recognize the boundaries between the punched regions 32 and the holeless regions 34 of the filter material 22 in the filter assembly 18 based on the intensity of light (light reception information) received by the light receiving unit 60b through the filter assembly 18 from the light emitting unit 60a. The filter assembly 18 can be inspected by the optical inspection device 60 that inspects such transmitted light intensity. Therefore, the control unit 60c can output the position and length of the first light transmitting portion 18a (punched region 32) and the position and length of the second light transmitting portion 18b (holeless region 34) between one end and the other end of the filter assembly 18. The control unit 60c outputs whether or not the plurality of punched regions 32 and the plurality of holeless regions 34 are set to the desired lengths that have been previously set. If the control unit 60c detects the punching regions 32 and the holeless regions 34 as having the desired lengths set in advance, for example, the control device of the manufacturing device 50 controls (feedback control) each device of the manufacturing device 50 (the supply unit 52, the processing unit 54, the rod forming unit 56, the rod cutting unit 58, etc.) to maintain the control state. On the other hand, if the control unit 60c detects the punching regions 32 and the holeless regions 34 as being out of the desired lengths set in advance, the control device of the manufacturing device 50 controls (feedback control) the control state of each device of the manufacturing device 50 so that the punching regions 32 and the holeless regions 34 have the desired lengths set in advance. For this reason, the control unit 60c controls the supply of the sheet material 30 by the supply unit 52 of the sheet material 30 and the punching of the sheet material 30 by the punching unit 66 based on the signal sent from the light receiving unit 60b to the control unit 60c.
　発光部６０ａから発光され、ラッパー２４となるシート状部材２４ａでロッド状に巻装した打ち抜き領域３２の、シート状部材２４ａ、ロッド状のフィルタ材２２、及び、シート状部材２４ａを通して受光部６０ｂで受光される光は、第１の光透過部１８ａ（打ち抜き領域３２）の光透過度の方が、第２の光透過部１８ｂ（ホールレス領域３４）の光透過度よりも高い。制御部６０ｃは、複数箇所の第１の光透過部１８ａ及び第２の光透過部１８ｂの光透過度の比較により、フィルタアセンブリ１８の複数の打ち抜き領域３２及び複数のホールレス領域３４の位置及び長さだけでなく、円柱状に形成されたフィルタ材２２（シート材３０）の品質管理を行うことができる。制御部６０ｃは、複数の第１の光透過部１８ａ（打ち抜き領域３２）における光透過度のバラツキが所定の閾値範囲内に抑えられていれば、フィルタアセンブリ１８の略円柱状のフィルタ材２２が略一定品質にラッパー２４となるシート状部材２４ａ内に保持されている、と出力する。同様に、制御部６０ｃは、複数の第２の光透過部１８ｂ（ホールレス領域３４）における光透過度のバラツキが所定の閾値範囲内に抑えられていれば、フィルタアセンブリ１８のフィルタ材２２が略一定品質にラッパー２４となるシート状部材２４ａ内に保持されている、と出力する。反対に、制御部６０ｃは、複数の第１の光透過部１８ａ及び／又は複数の第２の光透過部１８ｂにおける光透過度のバラツキが所定の閾値範囲を超えている場合、フィルタセグメント２０としたときの濾過性能にバラツキが生じる可能性がある。このため、フィルタアセンブリ１８のフィルタ材２２の品質が不良状態で、ラッパー２４となるシート状部材２４ａ内に保持されている、と出力する。 The light emitted from the light-emitting unit 60a and received by the light-receiving unit 60b through the sheet-like member 24a, the rod-shaped filter material 22, and the sheet-like member 24a of the punched area 32 wrapped in a rod shape with the sheet-like member 24a that becomes the wrapper 24 has a higher light transmittance in the first light-transmitting portion 18a (punched area 32) than in the second light-transmitting portion 18b (holeless area 34). By comparing the light transmittance of the first light-transmitting portion 18a and the second light-transmitting portion 18b at multiple locations, the control unit 60c can perform quality control of the cylindrically formed filter material 22 (sheet material 30) as well as the positions and lengths of the multiple punched areas 32 and multiple holeless areas 34 of the filter assembly 18. If the variation in light transmittance in the first light transmitting portions 18a (punchout regions 32) is kept within a predetermined threshold range, the control unit 60c outputs that the substantially cylindrical filter material 22 of the filter assembly 18 is held in the sheet-like member 24a that will become the wrapper 24 with substantially uniform quality. Similarly, if the variation in light transmittance in the second light transmitting portions 18b (holeless regions 34) is kept within a predetermined threshold range, the control unit 60c outputs that the filter material 22 of the filter assembly 18 is held in the sheet-like member 24a that will become the wrapper 24 with substantially uniform quality. On the other hand, if the variation in light transmittance in the first light transmitting portions 18a and/or the second light transmitting portions 18b exceeds the predetermined threshold range, the control unit 60c may cause variation in the filtering performance when the filter segment 20 is formed. For this reason, the control unit 60c outputs that the quality of the filter material 22 of the filter assembly 18 is poor and is held in the sheet-like member 24a that will become the wrapper 24.
　また、発光部６０ａの光を受光部６０ｂで受けた情報（第１の光透過部１８ａ及び／又は第２の光透過部１８ｂの光透過度）に基づいて、制御部６０ｃは、複数のフィルタアセンブリ１８同士の光強度の変化を比較してもよい。このとき、制御部６０ｃは、複数のフィルタアセンブリ１８同士の品質比較を行うことができる。 In addition, the control unit 60c may compare the changes in light intensity between the multiple filter assemblies 18 based on information (light transmittance of the first light transmitting portion 18a and/or the second light transmitting portion 18b) received by the light receiving portion 60b from the light emitting portion 60a. At this time, the control unit 60c can compare the quality between the multiple filter assemblies 18.
　なお、発光部６０ａの発光及び受光部６０ｂでの受光による測定は、例えばカメラの撮像素子等により適宜の時間間隔に周期的に撮像し、画像処理により行ってもよく、光強度の変化を連続的に測定してもよい。 The measurement based on the light emitted by the light-emitting unit 60a and the light received by the light-receiving unit 60b may be performed by, for example, periodically capturing images at appropriate time intervals using an image sensor in a camera and processing the images, or the change in light intensity may be measured continuously.
　このように、制御部６０ｃは、受光部６０ｂから送られる信号に基づいて、フィルタアセンブリ１８が所望の状態に形成されているか否か、出力することができる。すなわち、光学検査装置６０は、フィルタアセンブリ１８が所望の状態に形成されているか否か、出力することができる。 In this way, the control unit 60c can output whether or not the filter assembly 18 is formed in the desired state based on the signal sent from the light receiving unit 60b. In other words, the optical inspection device 60 can output whether or not the filter assembly 18 is formed in the desired state.
　制御部６０ｃのこのような出力に基づいて、製造装置５０の各装置（供給部５２、処理部５４、ロッド形成部５６、ロッド切断部５８等）をフィードバック制御することにより、品質を安定させることができる。このため、本実施形態に係る製造装置５０は、安定した品質のフィルタアセンブリ１８を製造することができる。 Based on such output from the control unit 60c, the quality can be stabilized by feedback controlling each device of the manufacturing apparatus 50 (the supply unit 52, the processing unit 54, the rod forming unit 56, the rod cutting unit 58, etc.). Therefore, the manufacturing apparatus 50 according to this embodiment can manufacture filter assemblies 18 of stable quality.
　本実施形態では、光学検査装置６０を、ロッド切断部５８の下流側に配置し、フィルタセグメント２０の４倍又は６倍などの所定長さに切断されたフィルタアセンブリ１８を検査する例について説明した。光学検査装置６０を、ロッド切断部５８の上流側に配置してもよい。この場合、トング７８により形成した、フィルタ材２２をラッパー２４となるシート状部材２４ａで巻装した状態で、上述した光学検査を行ってもよい。 In this embodiment, an example has been described in which the optical inspection device 60 is disposed downstream of the rod cutting section 58, and the filter assembly 18 cut to a predetermined length, such as four or six times the length of the filter segment 20, is inspected. The optical inspection device 60 may also be disposed upstream of the rod cutting section 58. In this case, the above-mentioned optical inspection may be performed in a state in which the filter material 22 formed by the tongs 78 is wrapped in the sheet-like member 24a that becomes the wrapper 24.
　各フィルタアセンブリ１８は、香味吸引物品１０用のフィルタセグメント２０として形成される際に、さらに切断される。このため、フィルタアセンブリ１８は、香味生成セグメント１２とチップペーパ１６を介して連結される前に切断され、フィルタセグメント２０が形成される。光学検査装置６０により行う検査結果に基づいて、例えば光学検査装置６０は、フィルタアセンブリ１８のシート状部材２４ａの外周面に打ち抜き領域３２とホールレス領域３４との境界であって、切断位置の印をつけておいてもよい。この場合、フィルタアセンブリ１８を切断する装置は、フィルタアセンブリ１８の切断位置、すなわち、複数のフィルタセグメント２０を得るためにフィルタアセンブリ１８を切断する位置を容易に把握することができる。このため、光学検査装置６０による検査結果を用いることで、フィルタアセンブリ１８を切断する装置において、フィルタアセンブリ１８を切断する位置を検出する作業を減らすことができる。 Each filter assembly 18 is further cut when it is formed into a filter segment 20 for the flavor inhalation article 10. Therefore, the filter assembly 18 is cut before being connected to the flavor generating segment 12 via the tipping paper 16 to form the filter segment 20. For example, based on the inspection results performed by the optical inspection device 60, the optical inspection device 60 may mark the cutting position on the outer peripheral surface of the sheet-like member 24a of the filter assembly 18, which is the boundary between the punched area 32 and the holeless area 34. In this case, the device that cuts the filter assembly 18 can easily grasp the cutting position of the filter assembly 18, that is, the position at which the filter assembly 18 is cut to obtain a plurality of filter segments 20. Therefore, by using the inspection results by the optical inspection device 60, the work of detecting the position at which the filter assembly 18 is cut can be reduced in the device that cuts the filter assembly 18.
　このように、それぞれ少なくとも１つの打ち抜き領域３２及びホールレス領域３４を有するフィルタセグメント２０は、フィルタアセンブリ１８を適宜に切断することにより得られる。このとき、複数の異なる性能を有する領域を１つの部材（シート材３０）で形成することができ、流体の例えば濾過量を調整し得る香味吸引物品１０用のフィルタセグメント２０が形成される。 In this way, the filter segment 20, each having at least one punched region 32 and holeless region 34, is obtained by appropriately cutting the filter assembly 18. At this time, a plurality of regions having different performance can be formed in one member (sheet material 30), and a filter segment 20 for a flavor inhalation article 10 is formed that can adjust, for example, the amount of filtration of a fluid.
　フィルタセグメント２０の一端は香味吸引物品１０の吸口端１４ｂとしてホールレス領域３４で形成される。フィルタセグメント２０の先端面１４ａは、香味吸引物品１０の香味生成セグメント１２の後端面１２ｂに突き当てられ、フィルタセグメント２０の先端面１４ａ及び香味生成セグメント１２の後端面１２ｂを含む領域をチップペーパ１６で巻装することで、香味吸引物品１０が製造される。 One end of the filter segment 20 is formed in a holeless region 34 as the suction end 14b of the flavor suction article 10. The tip surface 14a of the filter segment 20 is abutted against the rear end surface 12b of the flavor generating segment 12 of the flavor suction article 10, and the region including the tip surface 14a of the filter segment 20 and the rear end surface 12b of the flavor generating segment 12 is wrapped with tipping paper 16 to manufacture the flavor suction article 10.
　したがって、本実施形態によれば、性能が異なる領域（打ち抜き領域３２及びホールレス領域３４）を１つの部材（フィルタ材２２）で形成し、流体の濾過量等を調整し得る香味吸引物品１０及び香味吸引物品１０用のフィルタセグメント２０を提供することができる。 Therefore, according to this embodiment, it is possible to provide a flavor inhalation article 10 and a filter segment 20 for a flavor inhalation article 10 that can adjust the amount of fluid filtration, etc. by forming areas with different performance (punched area 32 and holeless area 34) in a single member (filter material 22).
　本実施形態では、ホールレスのシート材３０を巻いてボビン５２ａを形成し、製造装置５０により打ち抜き領域３２を形成する例について説明した。予め、打ち抜き領域３２及びホールレス領域３４が形成されたシート材３０を巻いてボビン５２ａを形成してもよい。このような予め、打ち抜き領域３２及びホールレス領域３４が形成されたシート材３０を用いて、フィルタセグメント２０を形成することも出来る。この場合、製造装置５０における打ち抜き部６６はなくてもよく、又は、上下ローラ６６ａ，６６ｂを取り外しておけばよい。 In this embodiment, an example has been described in which a holeless sheet material 30 is wound to form a bobbin 52a, and a punching area 32 is formed by a manufacturing device 50. The bobbin 52a may also be formed by winding a sheet material 30 on which a punching area 32 and a holeless area 34 have been formed in advance. The filter segment 20 can also be formed using such a sheet material 30 on which a punching area 32 and a holeless area 34 have been formed in advance. In this case, the punching section 66 in the manufacturing device 50 may not be necessary, or the upper and lower rollers 66a, 66b may be removed.
　本実施形態では、製造装置５０を用いてフィルタセグメント２０を含むフィルタアセンブリ１８を製造する例について説明した。製造装置５０は、フィルタセグメント２０以外の香味吸引物品１０用のロッドアセンブリ又はロッドセグメントを製造することもできる。例えば、シート材３０としてたばこシート材を用いると、開口３３を有する打ち抜き領域３２とホールレス領域３４とを有するたばこロッドが製造される。たばこシート材は、上述したシート材３０と同様にクレープ処理が行われて、ラッパー２４の代わりに巻紙で巻かれることで、香味生成セグメント１２のロッドが形成される。香味生成セグメント１２のロッドの充填物として、上述したシート材３０と同様にクレープ処理された、たばこシート材を用いる場合、フィルタセグメント２０のフィルタ材２２として、シート材３０を処理して用いる代わりに、例えばアセテートトウフィルタを用いてもよい。
　また、シート材３０としてたばこシート材には、添加部６８（図４参照）による後述するフィルタ材２２に対する添加剤と同様に、適宜の添加剤が添加され得る。 In the present embodiment, an example of manufacturing a filter assembly 18 including a filter segment 20 using the manufacturing apparatus 50 has been described. The manufacturing apparatus 50 can also manufacture rod assemblies or rod segments for flavor inhalation articles 10 other than the filter segment 20. For example, when a tobacco sheet material is used as the sheet material 30, a tobacco rod having a punched region 32 with an opening 33 and a holeless region 34 is manufactured. The tobacco sheet material is creped in the same manner as the above-mentioned sheet material 30, and wrapped with cigarette paper instead of the wrapper 24 to form a rod of the flavor generating segment 12. When a tobacco sheet material creped in the same manner as the above-mentioned sheet material 30 is used as the filling material of the rod of the flavor generating segment 12, an acetate tow filter, for example, may be used as the filter material 22 of the filter segment 20 instead of treating and using the sheet material 30.
Furthermore, appropriate additives may be added to the tobacco sheet material serving as the sheet material 30, similar to the additives added to the filter material 22 by an adding section 68 (see FIG. 4) as described below.
　第３実施形態で後述するが、冷却用のシート材３０を用いることにより、冷却セグメント４６を製造することも可能である。 As will be described later in the third embodiment, it is also possible to manufacture the cooling segment 46 by using a cooling sheet material 30.
　本実施形態によれば、性能が異なる領域を１つの部材で形成し、例えば上流から下流に流れる流体の状態を調整し得る香味吸引物品１０用のロッド（ロッドアセンブリ１８及びロッドアセンブリ１８を切断したロッドセグメント２０）を製造することが可能な製造装置５０、及び、香味吸引物品１０用のロッド（ロッドアセンブリ１８及びロッドアセンブリ１８を切断したロッドセグメント２０）の製造方法を提供することができる。 According to this embodiment, it is possible to provide a manufacturing device 50 capable of manufacturing a rod (rod assembly 18 and rod segments 20 cut from rod assembly 18) for a flavor inhalation article 10 that can form areas with different performance in a single member and adjust the state of a fluid flowing, for example, from upstream to downstream, and a manufacturing method for a rod (rod assembly 18 and rod segments 20 cut from rod assembly 18) for a flavor inhalation article 10.
　打ち抜き領域３２の開口３３は、幅方向に等間隔に形成される例について説明した。打ち抜き領域３２の開口３３は、幅方向にランダムに形成されていてもよい。打ち抜き領域３２の開口３３の配置は、フィルタセグメント２０が円柱状のロッドセグメントとして形成されたときに、開口３３が、適宜に均一的に配置され、偏りすぎていなければよい。 In the above description, the openings 33 in the punched region 32 are formed at equal intervals in the width direction. The openings 33 in the punched region 32 may be formed randomly in the width direction. The arrangement of the openings 33 in the punched region 32 may be such that the openings 33 are appropriately and uniformly arranged and are not excessively biased when the filter segment 20 is formed as a cylindrical rod segment.
　（第１変形例）
　次に、図１０を用いて、例えばフィルタセグメント２０のシート材３０の１つのセグメントＳが、打ち抜き領域３２及び２つのホールレス領域３４を有する例を、第１変形例として説明する。 (First Modification)
Next, with reference to FIG. 10, an example in which one segment S of the sheet material 30 of the filter segment 20 has a punched region 32 and two holeless regions 34 will be described as a first modified example.
　本変形例では、図１０に示すように、フィルタセグメント２０のフィルタ材２２は、１つの打ち抜き領域３２及び２つのホールレス領域３４をシート材３０の１つのセグメントＳとする。この場合、フィルタセグメント２０の先端面１４ａ及び吸口端１４ｂは、いずれも、ホールレス領域３４として形成することができる。 In this modified example, as shown in FIG. 10, the filter material 22 of the filter segment 20 has one punched area 32 and two holeless areas 34 as one segment S of the sheet material 30. In this case, both the tip surface 14a and the suction end 14b of the filter segment 20 can be formed as the holeless area 34.
　図示しないが、フィルタセグメント２０のシート材３０の１つのセグメントＳが、２つの打ち抜き領域３２及び１つのホールレス領域３４を有するものとしてもよい。 Although not shown, one segment S of the sheet material 30 of the filter segment 20 may have two punched regions 32 and one holeless region 34.
　上述した第１実施形態では、フィルタセグメント２０のロッドの長さは、例えば、１つの打ち抜き領域３２と１つのホールレス領域３４とを合わせた、シート材３０の１つのセグメントＳの長さとして形成されるものとした。フィルタセグメント２０のロッドの長さは、図１０に示すように、１つの打ち抜き領域３２と２つのホールレス領域３４とを合わせた長さとして形成されてもよく、図示しないが、２つの打ち抜き領域３２と２つのホールレス領域３４とを合わせた長さとして形成されてもよく、適宜に設定される。すなわち、シート材３０の１つのセグメントＳとして規定される範囲は適宜に設定可能である。 In the first embodiment described above, the length of the rod of the filter segment 20 is formed as the length of one segment S of the sheet material 30, for example, the length of one punched area 32 and one holeless area 34 combined. The length of the rod of the filter segment 20 may be formed as the length of one punched area 32 and two holeless areas 34 combined as shown in FIG. 10, or may be formed as the length of two punched areas 32 and two holeless areas 34 combined, not shown, and is set as appropriate. In other words, the range defined as one segment S of the sheet material 30 can be set as appropriate.
　このため、フィルタセグメント２０のロッドとしてのフィルタ材２２は、「ホールレス領域３４－打ち抜き領域３２－ホールレス領域３４」の並び（図１０参照）であったり、「打ち抜き領域３２－ホールレス領域３４－打ち抜き領域３２」の並び（図示せず）であったり、種々の並びがあり得る。 Therefore, the filter material 22 as the rod of the filter segment 20 can be arranged in various ways, such as "holeless region 34 - punched region 32 - holeless region 34" (see Figure 10) or "punched region 32 - holeless region 34 - punched region 32" (not shown).
　したがって、本変形例によれば、性能が異なる領域（打ち抜き領域３２及びホールレス領域３４）を１つの部材（シート材３０）で形成し、流体の濾過量等を調整し得る香味吸引物品１０及び香味吸引物品１０用のフィルタセグメント２０を提供することができる。また、本変形例によれば、このような香味吸引物品１０用のロッドセグメント（ロッド）２０を製造可能な製造装置５０、及び、香味吸引物品１０用のロッドセグメント（ロッド）２０の製造方法を提供することができる。 Accordingly, according to this modified example, it is possible to provide a flavor suction article 10 and a filter segment 20 for the flavor suction article 10 in which areas with different performance (punched area 32 and holeless area 34) are formed from a single member (sheet material 30) and the amount of fluid filtration, etc. can be adjusted. Furthermore, according to this modified example, it is possible to provide a manufacturing device 50 capable of manufacturing such a rod segment (rod) 20 for the flavor suction article 10, and a manufacturing method for the rod segment (rod) 20 for the flavor suction article 10.
　ある１つのセグメントＳを軸方向に繰り返して形成したフィルタアセンブリ（ロッドアセンブリ）１８の切断位置を調整して、１つのフィルタアセンブリ１８から、異なる長さで、異なる性質となるフィルタセグメント２０を得てもよい。すなわち、それぞれ１つの打ち抜き領域３２及びホールレス領域３４を１つの組とするフィルタセグメント（ロッドセグメント）２０、１つの打ち抜き領域３２及び２つのホールレス領域３４を１つの組とするフィルタセグメント（ロッドセグメント）２０、１つの打ち抜き領域３２及び１つのホールレス領域３４を１つの組とするフィルタセグメント（ロッドセグメント）２０などが形成される。 By adjusting the cutting position of a filter assembly (rod assembly) 18 formed by repeating a certain segment S in the axial direction, filter segments 20 of different lengths and with different properties may be obtained from a single filter assembly 18. That is, filter segments (rod segments) 20 each having one punched region 32 and one holeless region 34 as a set, filter segments (rod segments) 20 each having one punched region 32 and two holeless regions 34 as a set, filter segments (rod segments) 20 each having one punched region 32 and one holeless region 34 as a set, and filter segments (rod segments) 20 each having one punched region 32 and one holeless region 34 as a set are formed.
　フィルタアセンブリ（ロッドアセンブリ）１８のそれぞれホールレス領域３４の長手方向の真ん中で切断することにより、フィルタセグメント（ロッドセグメント）２０は、長手方向の両端をホールレス領域３４として形成することができる。このため、ある１つのセグメントＳを軸方向に繰り返して形成したフィルタアセンブリ（ロッドアセンブリ）１８の切断位置を調整して、１つのフィルタアセンブリ１８から、異なる長さで、異なる性質となるフィルタセグメント２０を得てもよい。 By cutting each of the holeless regions 34 of the filter assembly (rod assembly) 18 in the middle in the longitudinal direction, the filter segment (rod segment) 20 can be formed with holeless regions 34 at both longitudinal ends. Therefore, by adjusting the cutting position of the filter assembly (rod assembly) 18 formed by repeating one segment S in the axial direction, filter segments 20 of different lengths and with different properties can be obtained from one filter assembly 18.
　（第２変形例）
　次に、図１１を用いて、例えばフィルタセグメント２０のシート材３０の１つのセグメントＳが、打ち抜き領域が異なる２つの打ち抜き領域３２，３６、及び、ホールレス領域３４を有する例を、第２変形例として説明する。 (Second Modification)
Next, with reference to FIG. 11, an example in which, for example, one segment S of the sheet material 30 of the filter segment 20 has two different punched regions 32, 36 and a holeless region 34 will be described as a second modified example.
　上述した第１実施形態では、シート材３０の長手方向には、打ち抜き領域３２に隣接して上流側及び下流側ともにホールレス領域３４が形成される例について説明した。 In the first embodiment described above, an example was described in which holeless regions 34 are formed adjacent to the punched regions 32 on both the upstream and downstream sides in the longitudinal direction of the sheet material 30.
　図１１に示すように、シート材３０の長手方向に沿って、例えば上流側に、打ち抜き領域３２とは異なる打ち抜き量（％）の領域（別の打ち抜き領域）３６として形成してもよい。すなわち、シート材３０の１つのセグメントＳが、１つの打ち抜き領域３２と、１つのホールレス領域３４と、さらに別の打ち抜き領域３６とを有することも好適である。 As shown in FIG. 11, a region (another punching region) 36 with a different punching amount (%) from the punching region 32 may be formed along the longitudinal direction of the sheet material 30, for example on the upstream side. In other words, it is also preferable that one segment S of the sheet material 30 has one punching region 32, one holeless region 34, and yet another punching region 36.
　したがって、本変形例によれば、性能が異なる領域（打ち抜き領域３２及びホールレス領域３４）を１つの部材（シート材３０）で形成し、流体の濾過量等を調整し得る香味吸引物品１０及び香味吸引物品１０用のフィルタセグメント２０を提供することができる。また、本変形例によれば、このような香味吸引物品１０用のロッドセグメント（ロッド）２０を製造可能な製造装置５０、及び、香味吸引物品１０用のロッドセグメント（ロッド）２０の製造方法を提供することができる。 Accordingly, according to this modified example, it is possible to provide a flavor suction article 10 and a filter segment 20 for the flavor suction article 10 in which areas with different performance (punched area 32 and holeless area 34) are formed from a single member (sheet material 30) and the amount of fluid filtration, etc. can be adjusted. Furthermore, according to this modified example, it is possible to provide a manufacturing device 50 capable of manufacturing such a rod segment (rod) 20 for the flavor suction article 10, and a manufacturing method for the rod segment (rod) 20 for the flavor suction article 10.
　なお、本変形例では、１つのセグメントＳの１つの領域をホールレス領域３４として形成する例について説明した。２つ以上の領域で１つのセグメントＳを形成する場合、ホールレス領域３４の代わりに、打ち抜き領域３２に比べて打ち抜き量が比較的小さい打ち抜き領域３６を配置してもよい。この場合、吸口端１４ｂの見た目を維持しつつ、より低通気抵抗のフィルタセグメント２０となり得る。 In this modified example, an example has been described in which one region of one segment S is formed as the holeless region 34. When one segment S is formed from two or more regions, a punched region 36 having a relatively smaller punching amount than the punched region 32 may be disposed instead of the holeless region 34. In this case, the filter segment 20 can have lower airflow resistance while maintaining the appearance of the suction end 14b.
　（第３変形例）
　次に、図１２を用いて、フィルタセグメント２０の構成に関する第３変形例について説明する。 (Third Modification)
Next, a third modified example of the configuration of the filter segment 20 will be described with reference to FIG.
　図１２に示すフィルタセグメント２０のフィルタ材２２は、上述した第３変形例で説明したように、例えば、フィルタセグメント２０の上流側から下流側（吸口端１４ｂ側）に向かって、別の打ち抜き領域３６、打ち抜き領域３２、ホールレス領域３４の順に並んでいる（図１１参照）。フィルタセグメント２０の軸方向に沿って、別の打ち抜き領域３６と打ち抜き領域３２とが隣接し、打ち抜き領域３２とホールレス領域３４とが隣接して配置されている。 As explained in the third modified example above, the filter material 22 of the filter segment 20 shown in Figure 12 is arranged, for example, from the upstream side to the downstream side (the suction end 14b side) of the filter segment 20 in the order of another punched area 36, a punched area 32, and a holeless area 34 (see Figure 11). Along the axial direction of the filter segment 20, the another punched area 36 and the punched area 32 are adjacent to each other, and the punched area 32 and the holeless area 34 are adjacent to each other.
　本変形例では、打ち抜き領域３２には、ユーザの指や歯で好みのタイミングで割られるカプセル（シームレスカプセル）３８が埋設されている。例えば、打ち抜き領域３６の打ち抜き量（開口３３としての面積比）が３０％であるとし、打ち抜き領域３２の打ち抜き量（開口３３としての面積比）が７０％であるとし、これら領域３６，３２がフィルタセグメント２０のロッドの長手方向に沿って、連続している。ここでは、例えば、３つの領域３６，３２，３４のうち、打ち抜き量が最も多い打ち抜き領域３２には、１つのカプセル３８が配設され得る。 In this modified example, a capsule (seamless capsule) 38 is embedded in the punched area 32, which can be broken with the user's fingers or teeth at a time of their choice. For example, the punched amount (area ratio as opening 33) of the punched area 36 is 30%, and the punched amount (area ratio as opening 33) of the punched area 32 is 70%, and these areas 36, 32 are continuous along the longitudinal direction of the rod of the filter segment 20. Here, for example, one capsule 38 can be disposed in the punched area 32, which has the largest punched amount among the three areas 36, 32, 34.
　カプセル３８は、例えば滴下法により形成される。カプセル３８の直径は、例えば３ｍｍから６ｍｍであることが好適である。カプセル３８は、フィルタセグメント２０の製造の際に埋設され得る。 The capsules 38 are formed, for example, by a dropping method. The diameter of the capsules 38 is preferably, for example, 3 mm to 6 mm. The capsules 38 can be embedded during the manufacture of the filter segments 20.
　カプセル３８は皮膜で内容物の一例である香料を含む内容液を包み込んだ構造を有する。カプセル３８は、例えば略球体として形成される。皮膜形成材料は例えばデンプンとゲル化剤とを含む。ゲル化剤としてはたとえばジェランガムやゼラチンが用いられる。皮膜形成材料はさらにゲル化助剤を含んでもよい。ゲル化助剤としては例えば塩化カルシウムが用いられる。皮膜形成材料はさらに可塑剤を含んでもよい。可塑剤としてはグリセリンおよび／またはソルビトールが用いられる。皮膜形成材料はさらに着色料を含んでもよい。また、カプセル３８には液体とともに、又は、液体の代わりに、顆粒状など個体の内容物を含んでもよい。 Capsule 38 has a structure in which a liquid content, which includes a fragrance as an example of the contents, is enclosed in a membrane. Capsule 38 is formed, for example, as an approximately spherical shape. The membrane-forming material includes, for example, starch and a gelling agent. Examples of gelling agents that can be used include gellan gum and gelatin. The membrane-forming material may further include a gelling aid. Examples of gelling aids that can be used include calcium chloride. The membrane-forming material may further include a plasticizer. Examples of plasticizers that can be used include glycerin and/or sorbitol. The membrane-forming material may further include a coloring agent. Capsule 38 may also include solid contents, such as granules, together with or instead of the liquid.
　カプセル３８の内容液に含まれる香料としては、たとえばメンソール、植物精油などを用いることができる。内容液に含まれる香料の溶媒としては、例えば中鎖脂肪酸トリグリセリド（ＭＣＴ）を用いることができる。内容液はさらに色素、乳化剤、増粘剤などの他の添加剤を含有していてもよい。 The flavoring contained in the liquid content of capsule 38 may be, for example, menthol or vegetable essential oil. The solvent for the flavoring contained in the liquid content may be, for example, medium-chain triglyceride (MCT). The liquid content may further contain other additives such as colorants, emulsifiers, and thickeners.
　製造装置５０を用いてカプセル３８をフィルタ材２２に埋設する場合、例えば、図４に示す集束ガイド７４の終端とラップ糊ガン７６の糊がラッパー２４となるシート状部材２４ａに塗布される位置との間で、タイミングを計ってフィルタ材２２の打ち抜き領域３２に入れられる。例えば、光学検査装置６０を用いて、所望の位置、すなわち、フィルタ材２２の打ち抜き領域３２にカプセル３８が入っているか否かを確認してもよい。フィルタ材２２の打ち抜き領域３２にカプセル３８が入っていない場合、フィルタ材２２の打ち抜き領域３２にカプセル３８を入れるタイミングを調整してもよい。又は、光学検査装置６０を用いて、フィルタアセンブリ１８を検査する都度ごとに、フィードバック制御により、フィルタ材２２の打ち抜き領域３２にカプセル３８を入れるタイミングを調整してもよい。 When the manufacturing device 50 is used to embed the capsules 38 in the filter material 22, the capsules 38 are inserted into the punching area 32 of the filter material 22 at a timing between the end of the focusing guide 74 shown in FIG. 4 and the position where the glue from the wrap glue gun 76 is applied to the sheet-like member 24a that becomes the wrapper 24. For example, the optical inspection device 60 may be used to check whether the capsules 38 are inserted into the desired position, i.e., the punching area 32 of the filter material 22. If the capsules 38 are not inserted into the punching area 32 of the filter material 22, the timing of inserting the capsules 38 into the punching area 32 of the filter material 22 may be adjusted. Alternatively, the optical inspection device 60 may be used to adjust the timing of inserting the capsules 38 into the punching area 32 of the filter material 22 by feedback control each time the filter assembly 18 is inspected.
　このように、香味吸引物品１０のフィルタセグメント２０は、カプセル３８を含んでいてもよい。 In this manner, the filter segment 20 of the flavor inhalation article 10 may include a capsule 38.
　したがって、本変形例によれば、性能が異なる領域（打ち抜き領域３２，３６及びホールレス領域３４）を１つの部材（シート材３０）で形成し、流体の濾過量等を調整し得る香味吸引物品１０及び香味吸引物品１０用のロッドセグメント（フィルタセグメント）２０を提供することができる。また、本実施形態によれば、このような香味吸引物品１０用のロッドセグメント（ロッド）２０を製造可能な製造装置５０、及び、香味吸引物品１０用のロッドセグメント（ロッド）２０の製造方法を提供することができる。 Therefore, according to this modified example, it is possible to provide a flavor suction article 10 and a rod segment (filter segment) 20 for the flavor suction article 10 in which areas with different performance (punched areas 32, 36 and holeless area 34) are formed from a single member (sheet material 30) and the amount of fluid filtration, etc. can be adjusted. Furthermore, according to this embodiment, it is possible to provide a manufacturing device 50 capable of manufacturing such a rod segment (rod) 20 for the flavor suction article 10, and a manufacturing method for the rod segment (rod) 20 for the flavor suction article 10.
　本変形例では、フィルタ材２２が打ち抜き領域３６を有する例について説明したが、カプセル３８をフィルタ材２２内に埋設する構造において、打ち抜き領域３６は必ずしも必要ではない。 In this modified example, an example was described in which the filter material 22 has a punched-out region 36, but in a structure in which the capsule 38 is embedded in the filter material 22, the punched-out region 36 is not necessarily required.
　（第４変形例）
　次に、図１３Ａ及び図１３Ｂを用いて、フィルタセグメント２０の構成に関する第４変形例について説明する。本変形例は、第３変形例の更なる変形例である。 (Fourth Modification)
13A and 13B, a fourth modified example of the configuration of the filter segment 20 will be described. This modified example is a further modified example of the third modified example.
　図１３Ａに示すように、カプセル３８は、フィルタセグメント２０のフィルタ材２２に埋設されるのではなく、フィルタ材２２で形成されるフィルタセグメント２０とは別の、紙管又はアセテートトウがラッパー２７で巻装されたセグメント２６内に配設されることも好適である。すなわち、セグメント２６は、内側から外側に向かって順に、カプセル３８、紙管又はアセテートトウ等の中間部材２６ａ、ラッパー２６ｂを含む。この場合、セグメント２６は、吸口端１４ｂとは反対側の香味生成セグメント１２側に配置されることが好適である。したがって、例えばセグメント２６の先端面が香味生成セグメント１２の後端面１２ｂに当接する、マウスピースセグメント１４の先端面１４ａとなる。そして、セグメント２６の後端面にフィルタセグメント２０の先端面に当接される。なお、フィルタセグメント２０の後端面がマウスピースセグメント１４の吸口端１４ｂとなる。 As shown in FIG. 13A, it is also preferable that the capsule 38 is not embedded in the filter material 22 of the filter segment 20, but is disposed in a segment 26, which is separate from the filter segment 20 formed of the filter material 22 and is made of a paper tube or acetate tow wrapped with a wrapper 27. That is, the segment 26 includes, from the inside to the outside, the capsule 38, an intermediate member 26a such as a paper tube or acetate tow, and a wrapper 26b. In this case, it is preferable that the segment 26 is disposed on the flavor generating segment 12 side opposite the mouth end 14b. Therefore, for example, the tip surface of the segment 26 becomes the tip surface 14a of the mouthpiece segment 14, which abuts against the rear end surface 12b of the flavor generating segment 12. The rear end surface of the segment 26 abuts against the tip surface of the filter segment 20. The rear end surface of the filter segment 20 becomes the mouth end 14b of the mouthpiece segment 14.
　セグメント２６及びフィルタセグメント２０は、さらにラッパー２８で巻装されてマウスピースセグメント１４が形成される。 The segment 26 and the filter segment 20 are further wrapped with a wrapper 28 to form the mouthpiece segment 14.
　そして、香味生成セグメント１２の後端面１２ｂとマウスピースセグメント１４の先端面１４ａとが突き当てられた状態でチップペーパ１６により、香味生成セグメント１２の後端面１２ｂとマウスピースセグメント１４の先端面１４ａの外周が巻装される。このため、香味吸引物品１０が形成される。 Then, with the rear end surface 12b of the flavor generating segment 12 and the tip surface 14a of the mouthpiece segment 14 butted against each other, the outer circumference of the rear end surface 12b of the flavor generating segment 12 and the tip surface 14a of the mouthpiece segment 14 are wrapped with tipping paper 16. Thus, the flavor inhalation article 10 is formed.
　したがって、本変形例によれば、性能が異なる領域（打ち抜き領域３２及びホールレス領域３４）を１つの部材（シート材３０）で形成し、流体の濾過量等を調整し得る香味吸引物品１０及び香味吸引物品１０用のロッドセグメント（フィルタセグメント）２０を提供することができる。また、本変形例によれば、このような香味吸引物品１０用のロッドセグメント（ロッド）２０を製造可能な製造装置５０、及び、香味吸引物品１０用のロッドセグメント（ロッド）２０の製造方法を提供することができる。 Therefore, according to this modified example, it is possible to provide a flavor suction article 10 and a rod segment (filter segment) 20 for the flavor suction article 10 in which areas with different performance (punched area 32 and holeless area 34) are formed from a single member (sheet material 30) and the amount of fluid filtration, etc. can be adjusted. Furthermore, according to this modified example, it is possible to provide a manufacturing device 50 capable of manufacturing such a rod segment (rod) 20 for the flavor suction article 10, and a manufacturing method for the rod segment (rod) 20 for the flavor suction article 10.
　なお、図１３Ｂに示すように、カプセル３８を含むセグメント２６は、フィルタセグメント２０よりも吸口端１４ｂ側に設けられることも好適である。この場合、フィルタセグメント２０のフィルタ材２２はユーザから見えない。このため、フィルタセグメント２０の打ち抜き領域３２とホールレス領域３４との位置関係は、いずれが香味生成セグメント１２側であってもよい。
　図１３Ｂに示すフィルタセグメント２６は、吸口端１４ｂ側に「鬆（す）」を配置しない対策として用いることができる。このように、フィルタセグメント２０の後端側（吸口端１４ｂ側）にさらに別のセグメント２６を配置し、各セグメント２０，２６をラッパー（成型紙）２８で巻装してマルチセグメントフィルタとしてマウスピースセグメント１４を形成することができる。 13B, it is also preferable that the segment 26 including the capsule 38 is provided closer to the mouth end 14b than the filter segment 20. In this case, the filter material 22 of the filter segment 20 is not visible to the user. Therefore, the positional relationship between the punched region 32 and the holeless region 34 of the filter segment 20 may be such that either is on the flavor generating segment 12 side.
The filter segment 26 shown in Fig. 13B can be used as a measure to prevent the placement of "voids" on the mouth end 14b side. In this manner, another segment 26 can be placed on the rear end side (mouth end 14b side) of the filter segment 20, and each segment 20, 26 can be wrapped with a wrapper (molded paper) 28 to form the mouthpiece segment 14 as a multi-segment filter.
　図１３Ｂに示す例の場合でも、セグメント２０は、長手方向に沿って異なる性質を有する領域を形成するため、特定の性質を有するセグメントごとにラッパーで巻くことが一般である。これに対し、本変形例に係るセグメント２０は、１つのラッパー２４を用いるだけで長手方向に沿って異なる性質を有する領域を形成することができる。このため、通常に比べて、ラッパーの巻数を削減することができる。このため、フィルタセグメント２０に別セグメント２６を接続する場合であっても、ラッパー２８によって、マウスピースセグメント１４の外周が厚くなることを抑制することができる。 Even in the case of the example shown in FIG. 13B, the segment 20 forms regions with different properties along the longitudinal direction, so it is common to wrap each segment with a specific property with a wrapper. In contrast, the segment 20 of this modified example can form regions with different properties along the longitudinal direction using only one wrapper 24. This makes it possible to reduce the number of wrapper turns compared to normal. Therefore, even when another segment 26 is connected to the filter segment 20, the wrapper 28 can prevent the outer periphery of the mouthpiece segment 14 from becoming thicker.
　したがって、本変形例によれば、打ち抜き領域３２を有するシート材３０を用いて製造したフィルタセグメント２０の上流または下流に別のセグメント２６を配置して、マウスピースセグメント１４を、マルチセグメントフィルタとして形成することができる。 Accordingly, according to this modification, the mouthpiece segment 14 can be formed as a multi-segment filter by placing another segment 26 upstream or downstream of the filter segment 20 manufactured using the sheet material 30 having the punched-out region 32.
　（第５変形例）
　次に、図１４を用いて、例えばフィルタセグメント２０のシート材３０の打ち抜き領域３２及びホールレス領域３４に関する第５変形例について説明する。 (Fifth Modification)
Next, a fifth modification regarding, for example, the punched regions 32 and the holeless regions 34 of the sheet material 30 of the filter segment 20 will be described with reference to FIG.
　図１４に示すシート材３０の各打ち抜き領域３２は、シート材３０の長手方向（Ｘ軸方向）に沿って２段に形成された複数の円形孔の開口３３として形成される。ここでは、複数の円形孔の開口３３が長手方向に沿って２段である例について説明するが、シート材３０の長手方向に３段以上など、多段に形成されていることが好適である。 Each punched area 32 of the sheet material 30 shown in FIG. 14 is formed as a plurality of circular hole openings 33 formed in two stages along the longitudinal direction (X-axis direction) of the sheet material 30. Here, an example in which the plurality of circular hole openings 33 are formed in two stages along the longitudinal direction is described, but it is preferable that they are formed in multiple stages, such as three or more stages, along the longitudinal direction of the sheet material 30.
　本変形例での１つの打ち抜き領域３２において、上流側（－Ｘ軸方向側）の開口３３と、下流側（＋Ｘ軸方向側）の開口３３とは、幅方向（Ｙ軸方向）に並べた数及び形状が同一である。また、上流側（－Ｘ軸方向側）の複数の開口３３と、下流側（＋Ｘ軸方向側）の複数の開口３３とは、幅方向（Ｙ軸方向）に位置ズレしている。 In one punching region 32 in this modified example, the openings 33 on the upstream side (-X axis direction side) and the openings 33 on the downstream side (+X axis direction side) are the same in number and shape arranged in the width direction (Y axis direction). In addition, the multiple openings 33 on the upstream side (-X axis direction side) and the multiple openings 33 on the downstream side (+X axis direction side) are misaligned in the width direction (Y axis direction).
　シート材３０は上述した製造装置５０の打ち抜き部６６（図４参照）において、このような複数の円形孔の開口３３を形成するように形成されてもよい。又は、図１４に示す円形孔の開口３３が予め形成されたシート材３０がボビン５２ａに巻かれていてもよい。 The sheet material 30 may be formed in the punching section 66 (see FIG. 4) of the manufacturing apparatus 50 described above so as to form a plurality of circular hole openings 33. Alternatively, the sheet material 30 with the circular hole openings 33 pre-formed as shown in FIG. 14 may be wound around the bobbin 52a.
　このように、シート材３０における打ち抜き領域３２の位置、大きさ、形状等は、製造したい香味吸引物品１０用のフィルタセグメント２０に応じて適宜に設定される。 In this way, the position, size, shape, etc. of the punched area 32 in the sheet material 30 are appropriately set according to the filter segment 20 for the flavor inhalation article 10 to be manufactured.
　したがって、本変形例によれば、性能が異なる領域（打ち抜き領域３２及びホールレス領域３４）を１つの部材（シート材３０）で形成し、流体の濾過量等を調整し得る香味吸引物品１０及び香味吸引物品１０用のロッドセグメント（フィルタセグメント）２０を提供することができる。また、本変形例によれば、このような香味吸引物品１０用のロッドセグメント（ロッド）２０を製造可能な製造装置５０、及び、香味吸引物品１０用のロッドセグメント（ロッド）２０の製造方法を提供することができる。 Therefore, according to this modified example, it is possible to provide a flavor suction article 10 and a rod segment (filter segment) 20 for the flavor suction article 10 in which areas with different performance (punched area 32 and holeless area 34) are formed from a single member (sheet material 30) and the amount of fluid filtration, etc. can be adjusted. Furthermore, according to this modified example, it is possible to provide a manufacturing device 50 capable of manufacturing such a rod segment (rod) 20 for the flavor suction article 10, and a manufacturing method for the rod segment (rod) 20 for the flavor suction article 10.
　打ち抜き領域３２の打ち抜き形状、すなわち開口３３の形状は、任意の形状が許容される。開口３３には、角部を有するのではなければ、面取りがされていたり、ラウンド形状を有するような形状や円や楕円等であってもよい。この場合、シート材３０を打ち抜く際に、打ち抜きやすく、サクションで除去しやすい。なお、開口３３に角部が存在する場合、シート材３０を打ち抜いたときに、シート材３０と打ち抜き紙片の角部とが連結された状態のままとなる可能性があるが、開口３３に角部を有するのではなく、面取りがされていたり、ラウンド形状を有することにより、シート材に打ち抜き紙片が連結されたままとなることが抑制される。 The punched shape of the punching area 32, i.e., the shape of the opening 33, can be any shape. As long as the opening 33 does not have corners, it may be chamfered or rounded, or may be a circle, ellipse, or the like. In this case, when punching the sheet material 30, it is easy to punch and easy to remove by suction. If the opening 33 has corners, there is a possibility that the corners of the sheet material 30 and the punched piece of paper will remain connected when the sheet material 30 is punched out. However, by making the opening 33 chamfered or rounded rather than having corners, it is possible to prevent the punched piece of paper from remaining connected to the sheet material.
　（第２実施形態）
　第２実施形態について、図１５Ａ及び図１５Ｂを用いて説明する。本実施形態は第１実施形態の変形例であって、各変形例を含む第１実施形態で説明した部材と同一の部材又は同一の機能を有する部材には同一の符号を付し、詳しい説明を省略する。 Second Embodiment
The second embodiment will be described with reference to Figures 15A and 15B. This embodiment is a modification of the first embodiment, and the same members or members having the same functions as those described in the first embodiment including each modification are denoted by the same reference numerals, and detailed description thereof will be omitted.
　図１５Ａは、本実施形態に係る香味吸引物品１０の概略図を示す。香味吸引物品１０のフィルタセグメント２０の構造は、図１に示す香味吸引物品１０のフィルタセグメント２０の構造に対して上流側及び下流側が反対である。 FIG. 15A shows a schematic diagram of the flavor inhalation article 10 according to this embodiment. The structure of the filter segment 20 of the flavor inhalation article 10 is opposite to the upstream and downstream sides of the structure of the filter segment 20 of the flavor inhalation article 10 shown in FIG. 1.
　図１５Ｂは、本実施形態に係る製造装置５０における液体添加部６８ａ、及び、シート材３０を、液体添加部６８ａ、及び、シート材３０の上方から見た図を示す。 FIG. 15B shows the liquid addition unit 68a and the sheet material 30 in the manufacturing apparatus 50 according to this embodiment, viewed from above the liquid addition unit 68a and the sheet material 30.
　図１５Ｂに示すように、液体添加部６８ａは、例えば、第１のノズル６８１を有する。 As shown in FIG. 15B, the liquid adding section 68a has, for example, a first nozzle 681.
　第１のノズル６８１の複数の吐出部は、打ち抜き部６６（図４参照）で打ち抜かれた開口３３を含むシート材３０の長手方向に沿う領域Ｒ１に沿って適宜の粘度を有する第１の添加剤（例えば第１の液体）Ｌ１を吐出させ続ける。 The multiple ejection portions of the first nozzle 681 continue to eject a first additive (e.g., a first liquid) L1 having an appropriate viscosity along a region R1 along the longitudinal direction of the sheet material 30, which includes the opening 33 punched by the punching portion 66 (see FIG. 4).
　第１の添加剤Ｌ１は、例えば６０℃以上など、通常の大気温よりも高い温度で液体となり、通常の大気温に温度が低下すると、第１のノズル６８１からの吐出時に対して粘性が高くなる又は固まる性質を有することが好適である。 The first additive L1 preferably has the property of becoming liquid at a temperature higher than normal atmospheric temperature, for example 60°C or higher, and becoming more viscous or solidifying when ejected from the first nozzle 681 when the temperature drops to normal atmospheric temperature.
　シート材３０を長手方向に搬送しながら、第１のノズル６８１から第１の添加剤Ｌ１を吐出させ続けると、領域Ｒ１の開口３３内はＺ軸方向（上下方向）に挿通しているため、開口３３内には、第１の添加剤Ｌ１が付着しない。このため、第１の添加剤Ｌ１の少なくとも一部は、打ち抜き領域３２の開口３３内を通過する。すなわち、本実施形態に係る打ち抜き領域３２の開口３３内には、第１の添加剤Ｌ１が付着しない。なお、打ち抜き領域３２とホールレス領域３４との境界である、打ち抜き領域３２の開口３３の開口縁には、第１の添加剤Ｌ１が付着する。一方、シート材３０の長手方向に沿う領域Ｒ１の隣接する開口３３間のホールレス領域３４は、Ｚ軸方向（上下方向）に閉塞されている。このため、ホールレス領域３４には、第１の添加剤Ｌ１が付着する。したがって、ホールレス領域３４には、第１の添加剤Ｌ１が添加されている。
　このため、本実施形態では、シート材３０の長手方向に沿って、第１の添加剤Ｌ１がホールレス領域３４に付着し、打ち抜き領域３２に付着しない。したがって、シート材３０の図２に示す１つのセグメントＳ（フィルタ材２２）において、第１の添加剤Ｌ１が付着した領域（ホールレス領域３４）と、付着していない領域（打ち抜き領域３４）とを形成することができる。 When the first additive L1 is continuously discharged from the first nozzle 681 while the sheet material 30 is conveyed in the longitudinal direction, the opening 33 of the region R1 is inserted in the Z-axis direction (vertical direction), so the first additive L1 does not adhere to the opening 33. Therefore, at least a part of the first additive L1 passes through the opening 33 of the punching region 32. That is, the first additive L1 does not adhere to the opening 33 of the punching region 32 according to this embodiment. The first additive L1 adheres to the opening edge of the opening 33 of the punching region 32, which is the boundary between the punching region 32 and the holeless region 34. On the other hand, the holeless region 34 between the adjacent openings 33 of the region R1 along the longitudinal direction of the sheet material 30 is closed in the Z-axis direction (vertical direction). Therefore, the first additive L1 adheres to the holeless region 34. Therefore, the first additive L1 is added to the holeless region 34.
For this reason, in this embodiment, the first additive L1 adheres to the holeless region 34 and does not adhere to the punched region 32 along the longitudinal direction of the sheet material 30. Therefore, in one segment S (filter material 22) of the sheet material 30 shown in Figure 2, it is possible to form a region where the first additive L1 adheres (holeless region 34) and a region where the first additive L1 does not adhere (punched region 34).
　本実施形態でのフィルタセグメント（ロッドセグメント）２０の製造方法の一部となる、シート材３０への第１の添加剤Ｌ１の添加方法は、第１の添加剤Ｌ１の射出位置を固定しながら、搬送方向に沿って搬送するシート材３０の打ち抜き領域３２及びホールレス領域３４に交互に供給することを含む。第１の添加剤Ｌ１を打ち抜き領域３２の開口３３内を通過させることにより、ノズル６８１の位置を固定し、ノズル６８１から例えば下方に第１の添加剤Ｌ１を吐出させ続けるだけで、打ち抜き領域３２の開口３３内には第１の添加剤Ｌ１を付着させず、ホールレス領域３４には第１の添加剤Ｌ１を付着させることができる。そして、製造装置５０により、第１の添加剤Ｌ１が添加されたシート材３０をラッパー２４（シート状部材２４ａ）でフィルタセグメント（ロッドセグメント）２０として巻上げると、フィルタセグメント（ロッドセグメント）２０として、長手方向に異なる性質を有する領域を形成することができる。 The method of adding the first additive L1 to the sheet material 30, which is part of the manufacturing method of the filter segment (rod segment) 20 in this embodiment, includes alternately supplying the first additive L1 to the punching region 32 and the holeless region 34 of the sheet material 30 conveyed along the conveying direction while fixing the injection position of the first additive L1. By passing the first additive L1 through the opening 33 of the punching region 32, the position of the nozzle 681 is fixed, and the first additive L1 is simply continuously ejected from the nozzle 681, for example, downward, so that the first additive L1 is not attached to the opening 33 of the punching region 32, but is attached to the holeless region 34. Then, when the sheet material 30 to which the first additive L1 has been added is rolled up by the manufacturing device 50 with the wrapper 24 (sheet-like member 24a) as the filter segment (rod segment) 20, a region having different properties in the longitudinal direction can be formed as the filter segment (rod segment) 20.
　このため、フィルタ材２２をフィルタセグメント２０として形成したとき、図１５Ａに示すフィルタセグメント２０において、例えば、マウスピースセグメント１４の先端面１４ａ側を、第１の添加剤Ｌ１が付着するホールレス領域３４として形成し、マウスピースセグメント１４の後端面（吸口端）１４ｂ側を、第１の添加剤Ｌ１が付着していない打ち抜き領域３２として形成することができる。したがって、ユーザが香味吸引物品１０の吸口端１４ｂを口に咥えて吸引する際に、第１の添加剤Ｌ１の香味を適宜に感じることができる。
　なお、打ち抜き領域３２のうち、シート材３０の幅方向に間隔を開けて形成される開口３３の開口縁を含む、開口３３間の閉塞領域には、第１の添加剤Ｌ１の一部が添加されてもよい。 15A, for example, the tip surface 14a side of the mouthpiece segment 14 can be formed as a holeless region 34 to which the first additive L1 is attached, and the rear surface (suction end) 14b side of the mouthpiece segment 14 can be formed as a punched region 32 to which the first additive L1 is not attached. Therefore, when a user holds the suction end 14b of the flavor inhalation article 10 in his mouth and inhales, he can appropriately feel the flavor of the first additive L1.
In addition, a portion of the first additive L1 may be added to the blocked area between the openings 33, including the edges of the openings 33 formed at intervals in the width direction of the sheet material 30, in the punched area 32.
　本実施形態で説明するように、液体添加部６８ａから添加された液体を含むシート材３０を、ペーパフィルタとして用いる場合、第１の添加剤（液体）Ｌ１の漏れを抑えるために、下流側に液の少ないセグメントを配置するのが良い。そのため、フィルタセグメント２０の吸口端１４ｂ側には、第１の添加剤Ｌ１が付着するホールレス領域３４に対して下流側に、第１の添加剤Ｌ１の付着がない打ち抜き領域３２を配置することが好適である。 As described in this embodiment, when the sheet material 30 containing the liquid added from the liquid adding section 68a is used as a paper filter, it is preferable to place a segment with less liquid on the downstream side to prevent leakage of the first additive (liquid) L1. Therefore, on the suction end 14b side of the filter segment 20, it is preferable to place a punched area 32 to which the first additive L1 does not adhere, downstream of the holeless area 34 to which the first additive L1 adheres.
　なお、第１の添加剤Ｌ１として液体を用いる場合、耐液性を有するラッパー（巻取紙）２４が用いられることが好適である。 If a liquid is used as the first additive L1, it is preferable to use a wrapper (roller paper) 24 that is liquid-resistant.
　第１の添加剤Ｌ１としては、特定の成分に対して選択的に濾過性能を発揮するものがよい。フィルタ材２２（シート材３０）が紙材製である場合、フェノール吸着能を有する液体がよい。紙材製のフィルタ材２２に対して、例えば、ポリオール、ポリプロピレングリコール、ポリプロピレングリコールグリセリルエーテル、ポリブチレングリコール、ジグリセリン、ソルビタン脂肪酸エステル、グリセリン脂肪酸エステル、ポリグリセリン脂肪酸エステル、プロピレングリコール脂肪酸エステル、ポリエチレングリコールなどが用いられる。 The first additive L1 is preferably one that selectively exhibits filtering performance for specific components. When the filter material 22 (sheet material 30) is made of paper, a liquid that has phenol adsorption ability is preferable. For paper filter material 22, for example, polyol, polypropylene glycol, polypropylene glycol glyceryl ether, polybutylene glycol, diglycerin, sorbitan fatty acid ester, glycerin fatty acid ester, polyglycerin fatty acid ester, propylene glycol fatty acid ester, polyethylene glycol, etc. are used.
　第１の添加剤Ｌ１としての液体は粘度が比較的高いことが好適である。液体の粘度は、例えば、１ｃＰ～２００００ｃＰであることが好適であり、１０００ｃＰ～１００００ｃＰであることがさらに好適である。一般に、液体の粘度が高いと、ノズル６８１の吐出部のオン（開）／オフ（閉）に対する第１の添加剤Ｌ１の応答にタイムラグが生じる。すなわち、ノズル６８１をオン（開放）しても、第１の添加剤Ｌ１がシート材３０に流れるまでに時間がかかり、ノズル６８１をオフ（閉塞）しても、適宜の時間、液体がシート材３０に流れてしまう可能性がある。このため、シート材３０を例えば一定速度で搬送していても、第１の添加剤Ｌ１を添加したい領域と添加したくない領域を作ることが難しい。 The liquid as the first additive L1 preferably has a relatively high viscosity. For example, the viscosity of the liquid is preferably 1 cP to 20,000 cP, and more preferably 1,000 cP to 10,000 cP. In general, when the viscosity of the liquid is high, a time lag occurs in the response of the first additive L1 to the on (open)/off (close) of the discharge portion of the nozzle 681. That is, even if the nozzle 681 is turned on (open), it takes time for the first additive L1 to flow onto the sheet material 30, and even if the nozzle 681 is turned off (closed), the liquid may flow onto the sheet material 30 for an appropriate period of time. For this reason, even if the sheet material 30 is transported at a constant speed, for example, it is difficult to create areas where the first additive L1 is to be added and areas where it is not to be added.
　これに対し、本実施形態に係るシート材３０を用いることにより、例えば、シート材３０を長手方向に沿って移動させる際、ノズル６８１から直下に液体を吐出させ続けるときに、開口３３を通すことによって、ホールレス領域３４には第１の添加剤Ｌ１を付着させ、打ち抜き領域３２には第１の添加剤Ｌ１を付着させないようにすることができる。したがって、打ち抜き領域３２を第１の添加剤Ｌ１の添加がない領域として形成でき、ホールレス領域３４を第１の添加剤Ｌ１が添加された領域として形成することができる。このように、フィルタアセンブリ１８の製造者は、打ち抜き領域３２とホールレス領域３４とで、第１の添加剤Ｌ１の添加の有無を調整することができる。 In contrast, by using the sheet material 30 according to this embodiment, for example, when the sheet material 30 is moved along the longitudinal direction, and liquid is continuously ejected directly downward from the nozzle 681, the first additive L1 can be adhered to the holeless region 34 and the first additive L1 can be prevented from being adhered to the punched region 32 by passing through the opening 33. Therefore, the punched region 32 can be formed as a region where the first additive L1 is not added, and the holeless region 34 can be formed as a region where the first additive L1 is added. In this way, the manufacturer of the filter assembly 18 can adjust whether or not the first additive L1 is added to the punched region 32 and the holeless region 34.
　第１の添加剤（液体）Ｌ１の添加量は、１つのフィルタセグメント２０として、例えば、１ｍｇ～１００ｍｇであることが好適であり、５ｍｇから５０ｍｇであることがより好適である。 The amount of the first additive (liquid) L1 added per filter segment 20 is preferably, for example, 1 mg to 100 mg, and more preferably 5 mg to 50 mg.
　また、開口３３を通った液体はノズル６８１の直下のトレイ６８３（図４参照）等により回収され、再びノズル６８１に供給されるなど、再利用され得る。 In addition, the liquid that passes through the opening 33 can be collected by a tray 683 (see Figure 4) directly below the nozzle 681 and reused, such as by being supplied to the nozzle 681 again.
　したがって、本実施形態によれば、性能が異なる領域（打ち抜き領域３２及びホールレス領域３４）を１つの部材（シート材３０）で形成し、流体の濾過量等を調整し得る香味吸引物品１０及び香味吸引物品１０用のフィルタセグメント２０を提供することができる。また、本実施形態によれば、このような香味吸引物品１０用のロッドセグメント（ロッド）２０を製造可能な製造装置５０、及び、香味吸引物品１０用のロッドセグメント（ロッド）２０の製造方法を提供することができる。また、本実施形態によれば、添加剤Ｌ１の添加量が異なる領域（打ち抜き領域３２及びホールレス領域３４）を１つの部材（シート材３０）で形成することが可能な香味吸引物品１０用のロッドセグメント２０、及び、香味吸引物品１０用のロッドセグメント２０の製造方法を提供することができる。 Accordingly, according to this embodiment, it is possible to provide a flavor suction article 10 and a filter segment 20 for the flavor suction article 10, in which regions with different performances (punched region 32 and holeless region 34) are formed from a single member (sheet material 30) and the amount of fluid filtered can be adjusted. In addition, according to this embodiment, it is possible to provide a manufacturing device 50 capable of manufacturing such a rod segment (rod) 20 for the flavor suction article 10, and a manufacturing method for the rod segment (rod) 20 for the flavor suction article 10. In addition, according to this embodiment, it is possible to provide a rod segment 20 for the flavor suction article 10, in which regions with different amounts of additive L1 added (punched region 32 and holeless region 34) can be formed from a single member (sheet material 30), and a manufacturing method for the rod segment 20 for the flavor suction article 10.
　なお、本実施形態では、ノズル６８１を固定しながら、第１の添加剤Ｌ１をシート材３０に付着させる例について説明した。シート材３０に対して相対的にノズル６８１が所定方向に移動していれば、ノズル６８１は必ずしも固定されていなくてもよい。 In this embodiment, an example has been described in which the first additive L1 is applied to the sheet material 30 while the nozzle 681 is fixed. As long as the nozzle 681 moves in a predetermined direction relative to the sheet material 30, the nozzle 681 does not necessarily have to be fixed.
　本実施形態では、紙材製のシート材３０に第１の添加剤Ｌ１を添加する例について説明したが、打ち抜き領域３２及びホールレス領域３４をそれぞれ有する、不織布材製のシート材、樹脂材製のシート材、たばこシート材に対しても、同様に、第１の添加剤Ｌ１を添加することができる。すなわち、製造装置５０の第１の添加部６８ａに適用されるシート材３０は、紙材製、不織布材、樹脂材、たばこシート材等から適宜に選択される。 In this embodiment, an example of adding the first additive L1 to a paper sheet material 30 has been described, but the first additive L1 can also be added to a nonwoven sheet material, a resin sheet material, or a tobacco sheet material, each of which has a punched region 32 and a holeless region 34. That is, the sheet material 30 applied to the first addition section 68a of the manufacturing device 50 is appropriately selected from paper, nonwoven, resin, tobacco sheet material, etc.
　なお、図４に示す顆粒添加部６８ｂは、例えば香料顆粒、活性炭、微小カプセル、その他の顆粒をシート材３０に添加する。 The granule adding section 68b shown in FIG. 4 adds, for example, fragrance granules, activated carbon, microcapsules, and other granules to the sheet material 30.
　顆粒添加部６８ｂは、走行ガイド６９１と、走行ガイド６９１の直上に設けられる顆粒供給部６９２とを有する。走行ガイド６９１は、例えば所定速度でシート材３０を搬送する。顆粒供給部６９２は、例えば、打ち抜き領域３２及びホールレス領域３４に選択的に顆粒が添加される。顆粒としては、上述した活性炭が添加される。 The granule adding section 68b has a travel guide 691 and a granule supply section 692 provided directly above the travel guide 691. The travel guide 691 transports the sheet material 30 at a predetermined speed, for example. The granule supply section 692 selectively adds granules to, for example, the punching area 32 and the holeless area 34. The activated carbon described above is added as the granules.
　活性炭の密度は適宜に設定される。活性炭の一部は、シート材３０の例えば開口３３を通して落下する。落下した活性炭はトレイ等に集められる。 The density of the activated carbon is set appropriately. Some of the activated carbon falls through, for example, openings 33 in the sheet material 30. The fallen activated carbon is collected in a tray or the like.
　活性炭は、いわゆるチャコールフィルタと同様に、水分やタールの吸収に用いられる。活性炭の密度はホールレス領域３４の方が、打ち抜き領域３２よりも大きく形成されることが好適である。 Activated carbon is used to absorb moisture and tar, similar to so-called charcoal filters. It is preferable that the density of the activated carbon is greater in the holeless region 34 than in the punched region 32.
　微小カプセルは、ユーザにより潰されるカプセル３８（図１２参照）に比べて小さい粒径に形成される。粒径として例えば０．３ｍｍから４ｍｍ程度であることが好適である。微小カプセルには、香料が含まれ、例えば熱伝導に伴って外側から次第に微小カプセルが溶融し、香料を放出することができる。 The microcapsules are formed to have a smaller particle size than the capsules 38 (see FIG. 12) that are crushed by the user. A particle size of, for example, about 0.3 mm to 4 mm is preferable. The microcapsules contain a fragrance, and for example, the microcapsules melt gradually from the outside due to thermal conduction, allowing the fragrance to be released.
　なお、フィルタセグメント２０を形成する際に図１４に示すシート材３０を用いる場合、打ち抜き領域３２には、第１の添加剤Ｌ１が付着し得るが、付着量を、ホールレス領域３４に比べて抑制することができる。そのため、フィルタセグメント２０の吸口端１４ｂ側には、第１の添加剤Ｌ１の付着が少ない打ち抜き領域３２を配置することが好適である。 When the sheet material 30 shown in FIG. 14 is used to form the filter segment 20, the first additive L1 may adhere to the punched region 32, but the amount of adhesion can be suppressed compared to the holeless region 34. Therefore, it is preferable to place the punched region 32, where less first additive L1 adheres, on the suction end 14b side of the filter segment 20.
　ここでは、紙材製のシート材３０に顆粒を添加する例について説明したが、打ち抜き領域３２及びホールレス領域３４をそれぞれ有する、不織布材製のシート材、樹脂材製のシート材、たばこシート材に対しても、同様に、顆粒を添加することができる。すなわち、製造装置５０の第２の添加部６８ｂに適用されるシート材３０は、紙材製、不織布材、樹脂材、たばこシート材等から適宜に選択される。 Here, an example of adding granules to a paper sheet material 30 has been described, but granules can also be added to nonwoven sheet material, resin sheet material, and tobacco sheet material, each of which has a punched area 32 and a holeless area 34. In other words, the sheet material 30 applied to the second adding section 68b of the manufacturing device 50 is appropriately selected from paper, nonwoven sheet material, resin, tobacco sheet material, etc.
　本実施形態では、製造装置５０の流れに沿って、シート材３０に対して、開口３３を形成した後、第１の添加剤Ｌ１を添加するものとして説明した。第１の添加剤Ｌ１をシート材３０の長手方向に間欠的に添加するためには、ホールレスのシート材３０の長手方向に第１の添加剤Ｌ１を添加した後、上述した打ち抜き部６６を用いて開口３３を形成してもよい。このような製造方法によっても、結果として、シート材３０の長手方向に対して間欠的に第１の添加剤Ｌ１を添加（付着）させることができる。 In this embodiment, the first additive L1 is added to the sheet material 30 after the openings 33 are formed in the sheet material 30 along the flow of the manufacturing apparatus 50. In order to intermittently add the first additive L1 to the sheet material 30 in the longitudinal direction, the first additive L1 may be added to the holeless sheet material 30 in the longitudinal direction, and then the openings 33 may be formed using the punching section 66 described above. This manufacturing method also results in the first additive L1 being added (attached) intermittently to the sheet material 30 in the longitudinal direction.
　（第１変形例）
　第２実施形態の第１変形例について、図１６を用いて説明する。 (First Modification)
A first modified example of the second embodiment will be described with reference to FIG.
　図１６は、シート材３０を上から見た図を示す。図１６に示すように、液体添加部６８ａは、例えば、上述した第１のノズル６８１に加えて、第２のノズル６８２を有する。 FIG. 16 shows a top view of the sheet material 30. As shown in FIG. 16, the liquid addition section 68a has, for example, a second nozzle 682 in addition to the first nozzle 681 described above.
　第２のノズル６８２は、打ち抜き部６６で打ち抜かれた開口３３間を含む、長手方向に沿う領域Ｒ２に沿って適宜の粘度を有する第２の添加剤（例えば第２の液体）Ｌ２を吐出させ続ける。このため、第２の添加剤Ｌ２がシート材３０に添加される。 The second nozzle 682 continues to eject a second additive (e.g., a second liquid) L2 having an appropriate viscosity along a region R2 along the longitudinal direction, which includes the space between the openings 33 punched by the punching portion 66. As a result, the second additive L2 is added to the sheet material 30.
　第２の添加剤Ｌ２は、例えば６０℃以上など、通常の大気温よりも高い温度で液体となり、通常の大気温に温度が低下すると、吐出時に対して粘性が高くなる又は固まる性質を有することが好適である。なお、第１の添加剤（液体）Ｌ１の方が第２の添加剤（液体）Ｌ２より粘度が高いことが好適である。この場合、開口３３の縁部（打ち抜き領域３２とホールレス領域３４との境界）に付着した第１の添加剤Ｌ１は、開口３３から脱落し難い。このため、シート材３０を下流側に搬送するときも、添加部６８よりも後の製造装置５０に第１の添加剤Ｌ１が脱落して付着することを抑制することができる。なお、第２の添加剤Ｌ２の粘度は比較的低くても、シート材３０の閉塞領域のみに付着する場合が多い。このため、添加部６８よりも後の製造装置５０を、第２の添加剤Ｌ２がシート材３０から脱落して付着することは防止されている。 The second additive L2 preferably becomes liquid at a temperature higher than normal atmospheric temperature, for example, 60°C or higher, and has a property of becoming highly viscous or solidifying when discharged when the temperature drops to normal atmospheric temperature. It is preferable that the first additive (liquid) L1 has a higher viscosity than the second additive (liquid) L2. In this case, the first additive L1 attached to the edge of the opening 33 (the boundary between the punched area 32 and the holeless area 34) is unlikely to fall off from the opening 33. Therefore, even when the sheet material 30 is conveyed downstream, it is possible to prevent the first additive L1 from falling off and adhering to the manufacturing device 50 after the addition section 68. It is also possible to prevent the second additive L2 from falling off and adhering to the manufacturing device 50 after the addition section 68. It is also preferable that the second additive L2 has a relatively low viscosity, and is likely to adhere only to the closed area of the sheet material 30. Therefore, the second additive L2 is prevented from falling off the sheet material 30 and adhering to the manufacturing device 50 after the addition section 68.
　シート材３０を長手方向に搬送しながら、第２のノズル６８２から第２の添加剤Ｌ２を吐出させ続けると、領域Ｒ２には、領域Ｒ２の長手方向に沿って連続的に第２の添加剤Ｌ２が付着する。すなわち、シート材３０の長手方向に沿って、第２の添加剤Ｌ２は連続的に付着する。 When the second additive L2 is continuously ejected from the second nozzle 682 while the sheet material 30 is being transported in the longitudinal direction, the second additive L2 is continuously adhered to the region R2 along the longitudinal direction of the region R2. In other words, the second additive L2 is continuously adhered to the sheet material 30 along the longitudinal direction.
　本変形例でのフィルタセグメント（ロッドセグメント）２０の製造方法の一部となる、シート材３０への第２の添加剤Ｌ２の添加方法は、第２の添加剤Ｌ２の供給位置を第１の添加剤Ｌ１の供給位置に対して固定しながら、搬送方向に沿って搬送するシート材３０の打ち抜き領域３２及びホールレス領域３４に交互に供給することを含む。すなわち、第２の添加剤Ｌ２をシート材３０に添加することは、第２の添加剤Ｌ２の供給位置を第１の添加剤Ｌ１の供給位置に対して固定しながら、搬送方向に沿って搬送するシート材３０の打ち抜き領域３２の開口３３から外れた領域及びホールレス領域３４の両方に付着させることを含む。このため、ノズル６８２の位置を固定し、ノズル６８２から例えば下方に第２の添加剤Ｌ２を吐出させ続けるだけで、打ち抜き領域３２の開口３３間に第２の添加剤Ｌ２を付着させ、かつ、ホールレス領域３４に第２の添加剤Ｌ２を付着させることができる。そして、製造装置５０により、第２の添加剤Ｌ２が添加されたシート材３０をラッパー２４（シート状部材２４ａ）でフィルタセグメント（ロッドセグメント）２０として巻上げると、フィルタセグメント（ロッドセグメント）２０の長手方向に同じ添加剤Ｌ２を含ませた領域として形成することができる。 The method of adding the second additive L2 to the sheet material 30, which is part of the manufacturing method of the filter segment (rod segment) 20 in this modified example, includes alternately supplying the second additive L2 to the punching region 32 and the holeless region 34 of the sheet material 30 conveyed along the conveying direction while fixing the supply position of the second additive L2 relative to the supply position of the first additive L1. In other words, adding the second additive L2 to the sheet material 30 includes attaching the second additive L2 to both the region outside the opening 33 of the punching region 32 of the sheet material 30 conveyed along the conveying direction and the holeless region 34 while fixing the supply position of the second additive L2 relative to the supply position of the first additive L1. Therefore, by simply fixing the position of the nozzle 682 and continuing to eject the second additive L2 from the nozzle 682, for example, downward, the second additive L2 can be attached between the openings 33 of the punching region 32 and the holeless region 34. Then, when the sheet material 30 to which the second additive L2 has been added is wound up as a filter segment (rod segment) 20 with a wrapper 24 (sheet-like member 24a) by the manufacturing device 50, a region containing the same additive L2 can be formed in the longitudinal direction of the filter segment (rod segment) 20.
　このため、シート材３０を幅方向にクレープ処理し、フィルタ材２２をフィルタセグメント２０として形成したとき、フィルタセグメント２０において、例えば、マウスピースセグメント１４の先端面１４ａ側から後端面（吸口端）１４ｂ側まで、第２の添加剤Ｌ２が付着した領域として形成することができる。したがって、ユーザが香味吸引物品１０の吸口端１４ｂを口に咥えて吸引する際に、第２の添加剤Ｌ２の香味を適宜に感じることができる。このとき、香味生成セグメント１２で生じる香味と第２の添加剤Ｌ２からの香料成分とが接触する機会を長くすることができる。 Therefore, when the sheet material 30 is creped in the width direction and the filter material 22 is formed into the filter segment 20, the filter segment 20 can be formed with an area to which the second additive L2 is attached, for example, from the tip surface 14a side to the rear end surface (suction end) 14b side of the mouthpiece segment 14. Therefore, when the user holds the suction end 14b of the flavor inhalation article 10 in his mouth and inhales, he can appropriately feel the flavor of the second additive L2. At this time, the opportunity for contact between the flavor generated in the flavor generation segment 12 and the flavor component from the second additive L2 can be increased.
　なお、液体添加部６８ａは、第１のノズル６８１と、第２のノズル６８２から、シート材３０に対して、選択的に第１の添加剤Ｌ１、第２の添加剤Ｌ２を吐出してもよい。すなわち、液体添加部６８ａは、第１のノズル６８１からのみシート材３０に第１の添加剤Ｌ１を吐出させたり、第１のノズル６８１から第１の添加剤Ｌ１を吐出させず、第２のノズル６８２からのみシート材３０に第２の添加剤Ｌ２を吐出させたりすることができる。 The liquid adding unit 68a may selectively eject the first additive L1 and the second additive L2 onto the sheet material 30 from the first nozzle 681 and the second nozzle 682. That is, the liquid adding unit 68a can eject the first additive L1 onto the sheet material 30 only from the first nozzle 681, or eject the second additive L2 onto the sheet material 30 only from the second nozzle 682 without ejecting the first additive L1 from the first nozzle 681.
　本変形例では、紙材製のシート材３０に第１の添加剤Ｌ１及び／又は第２の添加剤Ｌ２を添加する例について説明したが、打ち抜き領域３２及びホールレス領域３４をそれぞれ有する、不織布材製のシート材、樹脂材製のシート材、たばこシート材に対しても、同様に、第１の添加剤Ｌ１及び／又は第２の添加剤Ｌ２を添加することができる。すなわち、製造装置５０の第１の添加部６８ａに適用されるシート材３０は、紙材製、不織布材、樹脂材、たばこシート材等から適宜に選択される。 In this modified example, an example of adding the first additive L1 and/or the second additive L2 to a paper sheet material 30 has been described, but the first additive L1 and/or the second additive L2 can also be added to a nonwoven sheet material, a resin sheet material, or a tobacco sheet material, each of which has a punched region 32 and a holeless region 34. That is, the sheet material 30 applied to the first addition section 68a of the manufacturing apparatus 50 is appropriately selected from paper, nonwoven, resin, tobacco sheet material, etc.
　したがって、本変形例によれば、性能が異なる領域（打ち抜き領域３２及びホールレス領域３４）を１つの部材（シート材３０）で形成し、流体の濾過量等を調整し得る香味吸引物品１０及び香味吸引物品１０用のフィルタセグメント２０を提供することができる。また、本変形例によれば、添加剤Ｌ１の添加量が異なる領域（打ち抜き領域３２及びホールレス領域３４）を１つの部材（シート材３０）で形成することが可能な香味吸引物品１０用のロッドセグメント２０、及び、香味吸引物品１０用のロッドセグメント２０の製造方法を提供することができる。 Therefore, according to this modified example, it is possible to provide a flavor suction article 10 and a filter segment 20 for the flavor suction article 10 in which regions with different performances (punched region 32 and holeless region 34) are formed from a single member (sheet material 30) and the amount of fluid filtered can be adjusted. Also, according to this modified example, it is possible to provide a rod segment 20 for the flavor suction article 10 in which regions with different amounts of additive L1 added (punched region 32 and holeless region 34) can be formed from a single member (sheet material 30), and a manufacturing method for the rod segment 20 for the flavor suction article 10.
　（第３実施形態）
　第３実施形態について、図１７を用いて説明する。本実施形態では、主に、非燃焼加熱型吸引物品１０の例について説明する。そして、第１実施形態で説明したシート材３０を用いて、ロッドセグメントとして先端プラグ４２を形成する例について説明する。 Third Embodiment
The third embodiment will be described with reference to Fig. 17. In this embodiment, an example of a non-combustion heating type suction article 10 will be mainly described. Then, an example in which a tip plug 42 is formed as a rod segment using the sheet material 30 described in the first embodiment will be described.
　図１７に示すように、本実施形態に係る香味生成セグメント１２は、先端プラグ４２と、香味生成部４４とを有する。 As shown in FIG. 17, the flavor generating segment 12 of this embodiment has a tip plug 42 and a flavor generating portion 44.
　本実施形態の香味生成部４４は、例えば、第１実施形態で説明した香味生成セグメント１２と同様に形成される。 The flavor generating section 44 of this embodiment is formed, for example, in the same manner as the flavor generating segment 12 described in the first embodiment.
　先端プラグ４２は、香味生成部４４の上流側に設けられる。先端プラグ４２は、例えばたばこ材料の脱落防止の目的などで用いられる。 The tip plug 42 is provided upstream of the flavor generating section 44. The tip plug 42 is used, for example, to prevent the tobacco material from falling off.
　本実施形態の先端プラグ４２は、第１実施形態で説明したフィルタセグメント２０と同様に形成される。すなわち、先端プラグ４２は、円柱状のフィルタ材２２と、フィルタ材２２の外周を覆うラッパー２４とを有する。また、先端プラグ４２では、打ち抜き領域３２とホールレス領域３４とが隣接して配置される。先端面１２ａを含む領域は、打ち抜き領域３２で形成される。本実施形態でのフィルタ材２２を形成するシート材３０の打ち抜き範囲は、打ち抜き領域３２の開口３３の面積が、フィルタセグメント２０として用いられる場合に比べて、大きくても小さくてもよい。また、例えば液体状の添加剤（第１の添加剤Ｌ１、第２の添加剤Ｌ２）や顆粒添加剤はあってもよく、なくてもよい。 The tip plug 42 of this embodiment is formed in the same manner as the filter segment 20 described in the first embodiment. That is, the tip plug 42 has a cylindrical filter material 22 and a wrapper 24 that covers the outer periphery of the filter material 22. In the tip plug 42, the punched area 32 and the holeless area 34 are arranged adjacent to each other. The area including the tip surface 12a is formed in the punched area 32. The punched range of the sheet material 30 that forms the filter material 22 in this embodiment may be larger or smaller than the area of the opening 33 in the punched area 32 when used as the filter segment 20. In addition, for example, liquid additives (first additive L1, second additive L2) or granular additives may or may not be present.
　先端プラグ４２の先端面１２ａを含む領域は、打ち抜き領域３２で形成される。本実施形態では、ホールレス領域３４と香味生成部４４とが連結される。 The area including the tip surface 12a of the tip plug 42 is formed in the punched area 32. In this embodiment, the holeless area 34 and the flavor generating section 44 are connected.
　先端プラグ４２には、図１５Ａから図１６に示すノズル６８１，６８２を用いて、プロピレングリコールやグリセリンなどのエアロゾル源が添加されるケースもある。 In some cases, an aerosol source such as propylene glycol or glycerin is added to the tip plug 42 using nozzles 681, 682 shown in Figures 15A to 16.
　なお、香味生成部４４の後端側には、マウスピースセグメント１４が設けられる。本実施形態では、マウスピースセグメント１４は、冷却セグメント４６と、フィルタセグメント４８とを有する。 The mouthpiece segment 14 is provided on the rear end side of the flavor generating section 44. In this embodiment, the mouthpiece segment 14 has a cooling segment 46 and a filter segment 48.
　本実施形態に係るフィルタセグメント４８は、第１実施形態で説明したフィルタセグメント２０を用いてもよく、例えばアセテートトウ等をロッド状とし、その外周をラッパー２４で巻いたフィルタセグメントを用いてもよい。 The filter segment 48 in this embodiment may be the filter segment 20 described in the first embodiment, or may be a filter segment made of, for example, acetate tow in a rod shape, the outer circumference of which is wrapped with a wrapper 24.
　非燃焼加熱型香味吸引物品１０を用いる場合、マウスピースセグメント１４は、香味生成セグメント１２の後端面１２ｂと、フィルタセグメント２０の先端面との間に、冷却セグメント４６を有することが好適である。すなわち、冷却セグメント４６は、香味生成セグメント１２の下流側に位置することが好適である。 When using a non-combustion heating type flavor inhalation article 10, it is preferable that the mouthpiece segment 14 has a cooling segment 46 between the rear end surface 12b of the flavor generating segment 12 and the tip surface of the filter segment 20. In other words, it is preferable that the cooling segment 46 is located downstream of the flavor generating segment 12.
　加熱されて気化した、エアロゾル基材や香味源の蒸気が冷却セグメント４６に導入されると冷却されて、凝縮（エアロゾル化）される。冷却セグメント４６は香味生成セグメント１２で発生したエアロゾル基材や香味源の蒸気を大きく除去することなく温度を冷却することが好ましい。例えば、吸引時に冷却セグメント４６の入口（香味生成セグメント１２の後端面１２ｂ近傍）のセグメント内部温度と冷却セグメント４６の出口（フィルタセグメント２０の先端面近傍）のセグメント内部温度との差が２０℃以上となることもある。 When the heated and vaporized aerosol base material or flavor source vapor is introduced into the cooling segment 46, it is cooled and condensed (aerosolized). It is preferable for the cooling segment 46 to cool the temperature without significantly removing the aerosol base material or flavor source vapor generated in the flavor generation segment 12. For example, during inhalation, the difference between the internal segment temperature at the inlet of the cooling segment 46 (near the rear end surface 12b of the flavor generation segment 12) and the internal segment temperature at the outlet of the cooling segment 46 (near the tip surface of the filter segment 20) may be 20°C or more.
　冷却セグメント４６のある態様としては、円筒状に加工した紙管に外気導入孔を形成した中空部材がある。別の態様としては、円筒状に加工した紙管の内部に冷却用のシート材を充填することも好ましい。冷却セグメント４６に用いられる冷却用のシート材は、例えば第１実施形態で説明したシート材３０からフィルタセグメント２０を製造するのと略同様に製造され得る、シート材を用いることが好適である。製造装置５０で冷却セグメント４６を製造する場合、上述した添加部６８は不要となり得る。 One aspect of the cooling segment 46 is a hollow member with an outside air inlet hole formed in a cylindrical paper tube. In another aspect, it is also preferable to fill the inside of the cylindrical paper tube with a cooling sheet material. The cooling sheet material used for the cooling segment 46 is preferably a sheet material that can be manufactured in a similar manner to the manufacturing of the filter segment 20 from the sheet material 30 described in the first embodiment. When the cooling segment 46 is manufactured using the manufacturing device 50, the above-mentioned addition section 68 may not be necessary.
　この際、冷却セグメント４６の流れ方向に一つまたは複数の空気流通チャネルを設けることで、冷却用のシート材による冷却を行ないつつ、低いレベルの成分濾過を達成できる。この冷却用のシート材を充填した際の冷却セグメント４６の通気抵抗は０ｍｍＨ２Ｏ／ｍｍ～３０ｍｍＨ２Ｏ／ｍｍであることが望ましい。 In this case, a low level of component filtration can be achieved while cooling is performed by providing one or more air flow channels in the flow direction of the cooling segment 46. It is desirable that the airflow resistance of the cooling segment 46 when filled with this cooling sheet material is 0 mmH2O /mm to 30 mmH2O /mm.
　冷却用のシート材の全表面積は、３００ｍｍ２／ｍｍ以上、１０００ｍｍ２／ｍｍ以下を挙げることができる。この表面積は、冷却用のシート材の通気方向の長さ（ｍｍ）当たりの表面積である。冷却用のシート材の全表面積は、４００ｍｍ２／ｍｍ以上であることが好ましく、４５０ｍｍ２／ｍｍ以上であることがより好ましく、一方、６００ｍｍ２／ｍｍ以下であることが好ましく、５５０ｍｍ２／ｍｍ以下であることがより好ましい。 The total surface area of the cooling sheet material may be 300 mm 2 /mm or more and 1000 mm 2 /mm or less. This surface area is the surface area per length (mm) of the cooling sheet material in the air passage direction. The total surface area of the cooling sheet material is preferably 400 mm 2 /mm or more, more preferably 450 mm 2 /mm or more, while it is preferably 600 mm 2 /mm or less, more preferably 550 mm 2 /mm or less.
　冷却セグメント４６は、エアロゾルと接触させるため、適宜の大きさの表面積を有することが望ましい。したがって、好ましい実施形態において、冷却用のシート材は、流れ方向にチャネルを形成するために皺付けされて、次に、襞（ひだ）付け、ギャザー付け、及び折り畳まれた薄い材料のシート材によって形成されてもよい。要素の与えられた体積内の折り畳み又は襞が多いと、冷却用のシート材の合計表面積が大きくなる。 It is desirable for the cooling segments 46 to have a suitable amount of surface area for contacting the aerosol. Thus, in a preferred embodiment, the cooling sheet may be formed from a thin sheet of material that is wrinkled to form channels in the flow direction, and then pleated, gathered, and folded. The more folds or pleats within a given volume of the element, the greater the total surface area of the cooling sheet.
　ある実施形態において、冷却用のシート材の厚さは、５μｍ以上、５００μｍ以下、例えば、１０μｍ以上、２５０μｍ以下を挙げることができる。 In one embodiment, the thickness of the cooling sheet material is 5 μm or more and 500 μm or less, for example, 10 μm or more and 250 μm or less.
　冷却用のシート材は、比表面積が１０ｍｍ２／ｍｇ以上、１００ｍｍ２／ｍｇ以下である材料から形成することが好適である。一実施形態において、構成材料の比表面積は、約３５ｍｍ２／ｍｇとすることができる。
　比表面積は、既知の幅及び厚みを有する冷却用のシート材の材料を考慮して決定することができる。例えば、冷却用のシート材の材料は、平均厚みが５０μｍであって変動が±２μｍであるポリ乳酸とすることができる。冷却用のシート材の材料が、同じく例えば２００ｍｍ以上、２５０ｍｍ以下の間の既知の幅を有する場合は、比表面積及び密度は、計算することができる。 The cooling sheet material is preferably made of a material having a specific surface area of 10 mm 2 /mg or more and 100 mm 2 /mg or less. In one embodiment, the specific surface area of the constituent material may be about 35 mm 2 /mg.
The specific surface area can be determined by considering the cooling sheet material having a known width and thickness. For example, the cooling sheet material can be polylactic acid with an average thickness of 50 μm and a variation of ±2 μm. If the cooling sheet material also has a known width, for example between 200 mm and 250 mm, the specific surface area and density can be calculated.
　また、冷却用のシート材の材料として紙材を用いることも環境負荷低減の観点で望ましい。冷却用のシート材としての紙材は、例えば、坪量が３０ｇ／ｍ２～１００ｇ／ｍ２、厚さ２０μｍ～１００μｍであることが望ましく。冷却セグメント４６における香味源成分とエアロゾル基材成分の除去を少なくするという観点では、冷却用のシート材としての紙の通気度は低いことが望ましく、通気度は１０コレスタユニット以下が好ましい。冷却用のシート材としての紙材にポリビニルアルコール等のポリマーポーティング、または、ペクチン等の多糖類のコーティングを施すことで、コーティングの吸熱や相変化に伴う溶解熱を利用して冷却効果を増大することもできる。 In addition, it is also desirable to use paper as the material for the cooling sheet material from the viewpoint of reducing the environmental load. For example, the paper as the cooling sheet material has a basis weight of 30 g/m 2 to 100 g/m 2 and a thickness of 20 μm to 100 μm. From the viewpoint of reducing the removal of flavor source components and aerosol base components in the cooling segment 46, it is desirable for the air permeability of the paper as the cooling sheet material to be low, and the air permeability is preferably 10 Coresta units or less. By applying a polymer porting such as polyvinyl alcohol or a coating of a polysaccharide such as pectin to the paper as the cooling sheet material, the cooling effect can be increased by utilizing the heat of dissolution accompanying the heat absorption or phase change of the coating.
　したがって、本実施形態によれば、性能が異なる領域（打ち抜き領域３２及びホールレス領域３４）を１つの部材（シート材３０）で形成し、流体の濾過量等を調整し得る香味吸引物品１０及び香味吸引物品１０用のフィルタセグメント２０を提供することができる。また、本実施形態によれば、このような香味吸引物品１０用のロッドセグメント（ロッド）２０を製造可能な製造装置５０、及び、香味吸引物品１０用のロッドセグメント（ロッド）２０の製造方法を提供することができる。 Therefore, according to this embodiment, it is possible to provide a flavor suction article 10 and a filter segment 20 for the flavor suction article 10 in which regions with different performance (punched region 32 and holeless region 34) are formed from a single member (sheet material 30) and the amount of fluid filtration, etc. can be adjusted. Furthermore, according to this embodiment, it is possible to provide a manufacturing device 50 capable of manufacturing such a rod segment (rod) 20 for the flavor suction article 10, and a manufacturing method for the rod segment (rod) 20 for the flavor suction article 10.
　第１実施形態で説明した製造装置５０を用いて、冷却用のシート材をクレープ処理加工して円柱状のロッドとして形成することで、マウスピースセグメント１４の冷却セグメント（冷却用のロッドセグメント）４６を形成することができる。 The manufacturing device 50 described in the first embodiment can be used to crepe the cooling sheet material to form it into a cylindrical rod, thereby forming the cooling segment (cooling rod segment) 46 of the mouthpiece segment 14.
　また、第１実施形態で説明した製造装置５０は、フィルタセグメント２０用だけでなく、本実施形態で説明した冷却セグメント４６用、香味生成セグメント（たばこシート材）１２用など、種々のシート材を、ラッパー２４となるシート状部材２４ａとともに巻上げて、円柱状のロッドセグメントとして形成することができる。 The manufacturing device 50 described in the first embodiment can roll up various sheet materials, not only for the filter segment 20, but also for the cooling segment 46 and flavor generating segment (tobacco sheet material) 12 described in this embodiment, together with the sheet-like member 24a that becomes the wrapper 24, to form cylindrical rod segments.
