[0008] The present invention relates to a method for manufacturing a smoking article comprising a tobacco rod, a cooling segment, and a filter segment. The present invention will be described in detail below. In the present invention, X to Y include the end values ​​X and Y.

[0009] 1. Smoking articles The smoking article of the present invention comprises a functional segment, a tobacco rod, a cooling segment, and a filter segment. Figure 1(i) shows one embodiment of the smoking article of the present invention. In the figure, 100 is the smoking article, 1 is the tobacco rod, 3 is the cooling segment, 5 is the filter segment, 7 is tipping paper, and 9 is the functional segment.

[0010] (1) Tobacco rod A tobacco rod is a generally cylindrical component for releasing the flavor and aroma components contained in tobacco raw materials, and comprises a tobacco filler material and a cigarette paper wrapped around it. The tobacco filler material is not limited, and examples include tobacco shreds and tobacco sheets. Specifically, cigarette paper may be filled with tobacco shreds, which are dried tobacco leaves cut into pieces with a width of 0.8 to 1.2 mm. Alternatively, dried tobacco leaves may be crushed and homogenized to an average particle size of approximately 20 to 200 μm, processed into a sheet, and then cut into pieces with a width of 0.8 to 1.2 mm. The sheet may be gathered, folded, or spirally wound without being cut, and then filled into cigarette paper. The sheet may also be cut into strips, which are then filled into cigarette paper concentrically or with the longitudinal direction of the strips parallel to the longitudinal direction of the tobacco rod.

[0011] The tobacco rod 1 may generate aerosol upon heating. To promote aerosol generation, it is preferable to add an aerosol source, such as glycerin, propylene glycol, or a polyol such as 1,3-butanediol, to the tobacco filler. The amount of the aerosol source added is preferably 5 to 50 wt %, more preferably 10 to 30 wt %, based on the dry weight of the tobacco filler. The tobacco rod may also contain a flavoring such as menthol. The length of the tobacco rod 1 is not particularly limited, but is preferably 15 to 25 mm. Its diameter is also not particularly limited, but is preferably 6.5 to 7.5 mm. However, if the rigidity of the adjacent members is higher than the rigidity of the tobacco rod itself, it is preferable that the diameter of the tobacco rod be larger than the diameter of the adjacent members. This is because deformation of the tobacco rod can be reduced. From this perspective, the diameter of the tobacco rod is preferably 0.5 to 2.5% larger than the diameter of the adjacent members, more preferably 1.0 to 2.0% larger. In terms of actual dimensions, the diameter of the tobacco rod is preferably about 0.05 to 0.15 mm larger than the diameter of the adjacent members, such as the cooling segment and the filter segment.

[0012] As disclosed in paragraphs 0010 to 0014 of the specification of JP-A No. 2016-523565, "rigidity" in the present invention refers to the resistance of a member to deformation. Rigidity can be calculated from the change in diameter before and after a load F is applied to the side of the tobacco rod. In FIG. 4, if the diameter of the tobacco rod before the load F is applied is Ds and the diameter after the load F is applied is Dd, the amount of depression is d = Ds - Dd, and rigidity is defined by the following formula. The same applies to other members. Stiffness (%)=Dd / Ds×100

[0013] (2) Cooling segment The cooling segment is a component for cooling the flavor and aroma components and aerosol generated in the tobacco rod 1. The cooling segment 3 may be a hollow paper tube. The paper tube is preferably made of cardboard, which has higher rigidity than cigarette paper or tipping paper. The paper tube may have openings (ventilation). Multiple openings are preferably provided along the circumference of the paper tube. From the standpoint of work efficiency, the openings are preferably provided by laser processing the completed smoking article. The cooling segment 3 may also be filled with a gathered sheet to improve heat exchange efficiency. The dimensions of the cooling segment 3 are not limited, but the length is preferably 15 to 25 mm, and the diameter is preferably 5.5 to 7.5 mm. However, if the rigidity of the component adjacent to the cooling segment 3 is lower than the rigidity of the cooling segment 3, the diameter of the cooling segment 3 is preferably 0.5 to 2.5% smaller than the diameter of the adjacent component, and preferably 1.0 to 2.0% smaller. Generally, when the cooling segment 3 has a cardboard tube, the rigidity of the segment is higher than the rigidity of the tobacco rod.

[0014] (3) Filter segment A filter segment is a component that includes a filter. Known filter components, such as acetate filters and paper filters, can be used as filters. A paper filter is a paper-filled filter prepared by processing paper using a crepe roller or the like to create wrinkles and wrapping it with plug wrapper paper. An acetate filter is a filter filled with cellulose acetate fibers. As shown in FIG. 1(ii), the filter segment 5 is preferably composed of multiple components, and more preferably includes a filter 51 and a center hole 53. The center hole can be, for example, an acetate filter with a space in the center. The length of the filter segment 5 is not limited, but is preferably 10 to 20 mm. When both a center hole and an acetate filter are arranged as a filter segment, their order is not limited. Furthermore, each component may be wrapped in filter wrapper paper (filter inner wrapper) and connected by molded filter paper (filter outer wrapper). The diameter of the filter segment is not limited, but it is preferably approximately the same diameter as the other segments other than the tobacco rod. This is because tearing and wrinkling of the tipping paper can be suppressed.

[0015] (4) Functional Segments The functional segment is a segment that imparts a function to the smoking article 100. For example, the functional segment 9 has the function of preventing tobacco shreds and the like from spilling from the tip of the tobacco rod 1, and the function of carrying a flavoring or the like to impart a unique flavor. In the former case, the functional segment 9 is preferably composed of a filter such as an acetate filter. In the latter case, the functional segment 9 is preferably a paper tube or filter in which a flavoring capsule is embedded. The length of the functional segment 9 is not limited, but is preferably 5 to 10 mm.

[0016] (5) Tipping paper Tipping paper refers to paper used to connect two or more of the tobacco rod, cooling segment, and filter segment. On the other hand, cigarette paper refers to paper used to wrap the individual components that make up the tobacco rod, cooling segment, or filter segment. For example, as mentioned above, if the filter segment has a center hole and an acetate filter, the paper wrapping the center hole and the paper wrapping the acetate filter are both cigarette paper.

[0017] The base paper used for the tipping paper and the cigarette paper is not limited, and examples thereof include those using cellulose fibers. Such cellulose fibers may be either plant-derived or chemically synthesized, or a mixture thereof. Examples of plant-derived fibers include pulp such as flax fiber, wood fiber, and seed fiber. Unbleached, colored pulp may be used, but bleached pulp bleached with a bleaching agent such as an oxidizing agent or a reducing agent is preferred to achieve a white, clean appearance.

[0018] In the case of cigarette papers for ordinary cigarettes, alkali metal citrates and the like are used as ordinary combustion modifiers (combustion improvers, etc.) that can affect the spontaneous combustion rate of the cigarette paper. In the present invention, a heated smoking article is preferred rather than a combustion-type smoking article, and in this case, the cigarette paper does not need to be burned, so the cigarette paper does not need to contain a combustion modifier.

[0019] The lower limit of the basis weight of the wrapper paper is preferably 30 g / m 2 More preferably, it is 35 g / m or more. 2 More preferably, it is 40 g / m or more. 2 The upper limit is preferably 65 g / m 2 Less than 50 g / m 2 The lower limit of the basis weight of the tip paper is preferably 20 g / m 2 More preferably, it is 25 g / m or more. 2 More preferably, it is 30 g / m or more. 2 The upper limit is preferably 50 g / m 2 Less than 45 g / m2 or less, more preferably 40 g / m 2 The basis weight can be measured by the method specified in JIS P8124.

[0020] 2. Manufacturing method An overview of this process is shown in Figure 2. In the figure, "w" indicates double length. For example, 5w indicates a double length filter segment. (1) Process A In this step, a double-length functional segment 9w having twice the length of the functional segment 9 and a segment A having tobacco rods 1 on both ends thereof is prepared. The double-length functional segment 9w and the tobacco rod 1 only need to be in contact with each other, and do not need to be bonded together.

[0021] Step A may include the following steps as shown in FIG. (A1) a step of preparing a pair of tobacco rods 1 and arranging them apart so that their longitudinal axes are aligned; (A2) A step of preparing a double-length functional segment 9w and arranging it in the spaced apart portion so that both ends thereof abut against the tobacco rod 1.

[0022] Step A may also include the following steps: (A1') a step of preparing a double-length tobacco rod 1w having twice the length of the tobacco rod 1, cutting the double-length tobacco rod 1w at its longitudinal center, separating the rods, and arranging the rods at a distance so that their longitudinal axes are aligned; (A2') A step of preparing a double-length functional segment 9w having twice the length of the functional segment 9, and placing it in the spaced apart portion so that both ends thereof abut against the tobacco rod 1, thereby preparing a double-length functional tobacco segment.

[0023] This step allows a function to be easily imparted to the upstream of the smoking article. For example, if the functional segment 9 is a filter, it can prevent the smoking article from falling off.

[0024] The manufacturing method of the present invention can be carried out using any device, but is preferably carried out using a device equipped with multiple drums, as shown in FIG. 5, in which each component is supplied from above. It is preferable that one drum has a single function rather than multiple functions, as this reduces the occurrence of defects during high-speed manufacturing. For example, step (A) can be carried out in the first unit 81 shown in FIG. 5. 81f is a tobacco rod 1 supply device, 81p is a take-out drum, and 81s is a separation drum. A pair of tobacco rods 1 supplied from the supply device 81f are transferred to a holder provided on the circumferential surface of the take-out drum 81p. The pair of tobacco rods 1 are then transferred to the separation drum 81s, where they are transported and separated from each other in the holder. Furthermore, the pair of tobacco rods 1 are transferred to the take-up drum 81a by a transfer drum 81t while still separated from each other.

[0025] Reference numeral 81'f denotes a supply device for the double-length functional segment 9w, and 81'p denotes a take-out drum. The double-length functional segment 9w supplied from the supply device 81'f is transferred to a holder provided on the circumferential surface of the take-out drum 81'p. Meanwhile, a pair of tobacco rods 1 are arranged spaced apart on the take-up drum 81a, and the double-length functional segment 9w is arranged at this spaced apart portion so as to abut against the tobacco rod 1. Each unit may have one or more drums having the functions of supplying, receiving, transporting, or separating.

[0026] (2) Process B The manufacturing method of the present invention preferably includes, between steps A and C, step B of wrapping and integrating segment A with a single sheet of second tipping paper 71. For convenience, the integrated segment A may also be referred to as segment B. Paper commonly used in this field can be used as second tipping paper 71. Second tipping paper 71 may be coated with a known adhesive, which integrates the functional segment and the tobacco rod, which were previously in a separable state, into an inseparable state.

[0027] The length of the second tipping paper used in this process can be adjusted to impart functionality to the smoking article. For example, if the length of the second tipping paper is long enough to cover the entire tobacco rod 1, even if a stain occurs on the tobacco rod 1, the stain can be concealed, maintaining a good appearance. Alternatively, the area covered by the second tipping paper 71 can be an area that starts at the joint surface between the tobacco rod 1 and the functional segment 9 and ends at a position 0.1X to 0.3X in the longitudinal direction of the tobacco rod 1, where X is the length of the tobacco rod 1. By setting the wrapping area within this range, a decrease in thermal conductivity can be avoided when the tobacco rod 1 is heated.

[0028] This step can be performed in the second unit 82 in Figure 5. 82f is a supply device for the second tipping paper 71, 82t is a transfer drum, 82r is a rolling drum, and 82h is a rolling hand. This step is similar to step F, and so details will be explained in step F.

[0029] (3) Process C In this step, a pair of cooling segments 3 are prepared and placed in contact with both ends of segment B, thereby preparing segment C.

[0030] This step can be performed in the third unit 83 in Figure 5. 83f is a supply device for the cooled segments 3, 83ps is a take-out separation drum, and 83a is a take-up drum. The pair of cooled segments 3 supplied from the supply device 83f are transferred to a holder provided on the circumferential surface of the take-out separation drum 83ps and separated from each other. Meanwhile, segment B prepared in the previous step is transferred to the take-up drum 83a via a transfer drum 83t. The pair of cooled segments 3 are transferred to the take-up drum 83a and are positioned at both ends of segment B so as to abut against the end faces of the tobacco rod 1.

[0031] (4) Process D In this step, the segment C is cut at the center in the longitudinal direction to separate it, and a pair of segments D is prepared. Then, these are inverted and arranged so that the longitudinal axes of both segments are the same and the cooling segments 3 face each other at a distance.

[0032] This process can be performed in the fourth unit 84 in Figure 5. 84c is a cutter drum, and 84c' is a cutter. Segment B is delivered to the cutter drum 84c and cut by the cutter 84c' at the center in the longitudinal direction. The segment is then delivered to two reversing drums 84i and inverted. The inversion mechanism will be explained with reference to Figure 6. Guide G on the reversing drum 84i is a holding part that holds the two divided segments C, i.e., segment D, and is installed on the drum so that it can rotate around one corner. Segment D, held by guide G shown by dotted lines, rotates as the reversing drum 84i rotates and moves to the position shown by solid lines. Segment D is then delivered to guide G' shown by dotted lines on the reversing drum 84i'. Guide G' slides on the reversing drum 84i' and moves to the position shown by solid lines where the separation distance between the pair of segments D is the desired value. In this way, a pair of divided segments C is inverted.

[0033] (5) Process E In this step, a double-length filter segment 5w having twice the length of the filter segment 5 is prepared, and placed in the spaced apart portion so that both ends thereof abut the cooling segment side ends of the segment D to prepare segment E.

[0034] This step can be performed in the fifth unit 85 in Figure 5. 85f is a supply device for the double-length filter segments 5w, 85p is a take-out drum, and 85a is a take-up drum. The double-length filter segments 5w supplied from the supply device 85f are transferred to a holder provided on the circumferential surface of the take-up drum 85p. Meanwhile, the pair of segments D are transferred to the take-up drum 85a while remaining spaced apart, so the double-length filter segments 5w are transferred from the take-out drum 85p to the space between the pair of segments D on the take-up drum 85a.

[0035] (6) Process F In this step, the segments E are wrapped and integrated with a single sheet of tipping paper 7 to prepare a double-length smoking article 100w having twice the length of the smoking article 100. The tipping paper 7 may be the same as the second tipping paper 71. As a result, the segments E, which were previously in a separable state, are integrated and become inseparable. In this case, the tipping paper 7 does not need to cover the entire area of ​​the tobacco rod 1. When the length of the tobacco rod 1 is X, the area covered by the tipping paper 7 preferably extends from the joint surface between the tobacco rod 1 and the cooling segment 3 as the starting point to a position 0.2X to 0.4X in the longitudinal direction of the tobacco rod 1 as the end point. By limiting the wrapping area to this range, a decrease in thermal conductivity can be avoided when the tobacco rod 1 is heated.

[0036] This process can be performed in the sixth unit 86 in Figure 5. 86f is a tipping paper 7 supply device, 86t is a transfer drum, 86r is a rolling drum, and 86h is a rolling hand. The rolling drum is a drum equipped with a holding portion that holds components on its circumferential surface, allowing components such as segments to rotate around their longitudinal central axis. The rolling hand is disposed opposite the circumferential surface of the rolling drum and is a means for forming a gap with a certain distance between the surface. The segment E is transferred to the transfer drum 86t and then to the rolling drum 86r. Meanwhile, a portion of the tipping paper 7 supplied from the supply device 86f is adhered to the circumferential surface of the segment E on the rolling drum 86r, forming a precursor 92 (see Figure 7). The precursor 92 includes tipping paper 7 adhered to the segment E, denoted by 90, like a flag. That is, a portion of the tipping paper 7 is adhered to the circumferential surface of the segment E, while the other portion is free. The precursor 92 is fixed to a holder on the circumferential surface of the rolling drum 86r by suction or the like, and is transported to the gap formed between the rolling drum 86r and the rolling hand 86h. As the precursor 92 passes through this gap, the entire circumferential surface of the precursor 92 is wrapped with tipping paper 7, forming a double-length smoking article 100w (see FIG. 7).

[0037] As mentioned above, in the present invention, it is preferable that the diameter of the tobacco rod 1 is larger than the diameter of the adjacent cooling segment 3. In this case, if the surfaces of the rolling drum 86r and the rolling hand 86h are flat, the tobacco rod 1 will come into excessive contact with these surfaces (FIG. 8(1)), causing an impact on the tobacco rod 1 and causing the filler to fall, a problem known as "tip-drop." Furthermore, twisting due to the difference in circumference occurs, resulting in defects such as wrinkles in the product. Therefore, in the present invention, as shown in FIGS. 8(2) and 8(3), it is preferable to provide a recess on the surface of the rolling drum 86r or the rolling hand 86h facing the tobacco rod 1 to form a gap between the tobacco rod 1 and the rolling hand 86h. While FIGS. 8(2) and 8(3) show an embodiment in which a recess is provided on the rolling hand 86h, the recess may also be provided on the rolling drum 86r, or on both. The depth of the recess (T in FIGS. 8(2) and 8(3)) can be adjusted as needed, but is preferably 0.05 to 0.15 mm. The recesses do not need to be provided on the entire surface facing the tobacco rod 1. As shown in Fig. 8, the recesses may be provided on only a part of the surface facing the tobacco rod 1. However, in order to reliably bond the tobacco rod and other components with the tipping paper, it is preferable that no recesses exist near the boundary between the two components.

[0038] In the present invention, the segment E is wrapped with one piece of tipping paper in the final stage, which avoids unevenness on the product that occurs when multiple pieces of tipping paper are used, and reduces the rate of defective products produced in the manufacturing process.

[0039] (7) Process G In this step, the double-length smoking article 100w is cut at the center in its longitudinal direction to form the smoking article 100. This step may further include a step of inverting one of the smoking articles 100 to align the directions of the two smoking articles 100.

[0040] This step can be carried out in the seventh unit 87 in Fig. 5. 87c is a cutter drum, 87c' is a cutter, and 87a is a take-up drum. Cutting is carried out as described in step D.

[0041] In the present invention, the double-length functional segment 9w is placed in the center, then cut and separated at the center and turned over, which allows for efficient work when imparting functionality to the tip end of the smoking article.

[0042] [Example 1] The following components were prepared: Tobacco rod with a diameter of 7.0 mm and a length of 20.0 mm (manufactured by Japan Tobacco Inc.) Double-length functional segment: 6.9mm diameter, 16mm length acetate filter The cooling segment is a paper tube with a diameter of 6.9 mm and a length of 20.0 mm. A double-length filter segment with a diameter of 6.9 mm, consisting of a center hole (8.0 mm) / double-length acetate filter (14.0 mm) / center hole (8.0 mm). 24mm x 26mm second tip paper 24.0mm x 80.0mm 1st tip paper

[0043] A double-length tobacco rod was prepared, cut at its longitudinal center, and separated, and then spaced apart so that the longitudinal axes of both rods were aligned. Next, a double-length functional segment was placed at the spaced apart position, thereby preparing segment A, which included a double-length functional segment and the tobacco rods at both ends (step A).

[0044] Segment A was wrapped with a single sheet of second tipping paper to form a single unit, thereby preparing segment B (step B). A pair of paper tubes were prepared and placed in contact with both ends of segment B to prepare segment C (step C). Segment C was cut and separated at its longitudinal center to prepare a pair of segments D, which were then inverted and placed at a distance such that their longitudinal axes were aligned and the paper tubes faced each other (step D). A double-length filter segment having twice the length of the filter segment was prepared and placed at the separated portion so that its both ends abutted the paper tube-side end of segment D to prepare segment E (step E). Segment E was wrapped with a single sheet of tipping paper to form a single unit, thereby producing a double-length smoking article having twice the length of the smoking article (step F). The double-length smoking article was cut at its longitudinal center to produce a smoking article (step G). [Explanation of symbols]
