Description

Manufacturing method of smoking goods

The present invention relates to a method for producing a smoking article.

Patent Document 1 includes a first multi-segment component in which a flammable carbonaceous heat source, an aerosol-forming substrate, and an airflow directional element (annular member) are wrapped in a wrapper (wrapping paper), and a second having an expansion chamber and a mouthpiece. A smoking article in which the multi-segment components of the above are wrapped in an outer wrapper (wrapping paper) is disclosed. A removable cap is located at the end of the smoking article adjacent to the heat source, and the cap is wrapped with a portion of the wrapper of the first multi-segment component.

Then, a series of continuously wrapped first multi-segment components are cut at the portion of the air flow directional component using a cutter, and a cap is formed of the same material as the air flow directional component to form a second multi-segment component. Smoking articles are manufactured by combining with the elements.

Further, the segments constituting the first and second multi-segment components other than the cap are supplied from the hopper on the moving delivery path and are connected by the compactor.

Special Table 2015-536673

In Patent Document 1, the segments constituting the multi-segment component other than the cap are supplied in a preformed state that has already been cut into a shape constituting the smoking article. Therefore, even if the segment has a short segment length and a small aspect ratio (aspect ratio), it must be placed and supplied in an appropriate posture on the moving delivery path.

In addition, such a small segment must be transported while maintaining its initial posture so as not to roll even after being placed on the delivery path. Therefore, if the posture of the segment is lost during the supply and transportation of the segment and the segment rolls, the quality of the finally manufactured smoking article may be deteriorated. Further, in order to prevent such a defect, it is necessary to prepare equipment having a complicated mechanism for preventing the rolling of a small segment, which deteriorates the productivity of smoking articles.

Also, the cap is formed by cutting the airflow directional element in the manufacturing process of smoking articles. Therefore, the cutting step must be performed solely for the purpose of forming the cap, which also deteriorates the productivity of the smoking article.

Further, when a smoking article is manufactured by winding a connecting body composed of other components with a wrapping paper with the cap positioned at the end, the cap positioned at the end is wound when the connecting body is wound up with the wrapping paper. It has a role as a segment that influences the upper suitability (appropriateness that enables the peripheral surface of the winding target to be wound evenly and uniformly). However, in Patent Document 1, no special consideration is given to the case where such a manufacturing method is used. Therefore, if an airflow directional element, that is, a cap that merely functions as a tubular member is used, the winding suitability is improved. It may worsen and lead to poor quality of smoking goods.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a method for producing a smoking article, which can realize both quality improvement and productivity improvement of the smoking article. It is in.

In order to achieve the above object, the method for producing a smoking article of the present invention supplies two hoisting members, two heat sources and one flavor source material, and supplies the hoisting member, heat source, flavor source material, and heat source. , The first arrangement step of forming the first connecting body in which the hoisting members are arranged in a row in this order, and the first winding up in which the first connecting body is integrally wound with the first winding paper to form the first continuous body. The process and the first continuum are cut in the flavor source material and divided into two, and the hoisting member, the heat source, and the flavor source material are divided into two to form two intermediate rods in which the flavor sources are arranged in a row in this order. In the first cutting step, the filter member material is supplied, and the intermediate rod, the filter member material, and the intermediate rod are arranged in a row in this order with the flavor sources of the two intermediate rods facing both ends of the filter member material. The second arrangement step of forming the second connecting body, the second winding step of integrally winding the second connecting body with the second winding paper to form the second continuous body, and the second winding body in the filter member material. It includes a second cutting step of forming two smoking articles in which the filter members formed by cutting and halving the hoisting member, the heat source, the flavor source, and the filter member material are arranged in a row in this order.

According to the method for producing a smoking article of the present invention, both quality improvement and productivity improvement of the smoking article can be realized.

Hereinafter, a method for producing a smoking article according to an embodiment of the present invention will be described with reference to the drawings.
<First Embodiment>
FIG. 1 shows a schematic cross-sectional view of the smoking article 1 according to the first embodiment of the present invention in the axial direction X. The smoking article 1 is a heat source type cigarette formed by arranging the hoisting member 2, the heat source 3, the flavor source 4, and the filter member 5 in a row in the axial direction X in this order.

The smoking article 1 includes a first roll paper 6 that integrally winds the hoisting member 2, a heat source 3, and a flavor source 4, and a hoisting member 2, a heat source 3, and a flavor source 4 that are wound up by the first roll paper 6. Further, it includes a second roll paper 7 that is integrally wound with the filter member 5. Further, the smoking article 1 is provided on the side of the hoisting member 2, a part of the heat source 3, the adhesive portion 8 for adhering the flavor source 4 and the first roll paper 6, and the hoisting member 2 of the heat source 3. It includes a non-adhesive portion 9 that does not adhere the remaining part of the heat source 3 and the first roll paper 6. The smoking article 1 is used by detaching the hoisting member 2 at the non-adhesive portion 9 so that at least a part of the heat source 3 can be heated by ignition.

[Hoisting member]
The hoisting member 2 of the present embodiment is, for example, a paper tube when the first connecting body 13 formed in the first arrangement step described later is wound up by the first roll paper 6 in the first hoisting step described later. It is a member for improving the winding suitability. The hoisting member 2 also has a function of covering and protecting the heat source 3 at the time of manufacturing and before using the smoking article 1.

Appropriate winding means the appropriateness that enables the peripheral surface of the object to be wound to be wound evenly and evenly. The smoking article 1 provided with the hoisting member 2 can eliminate hoisting defects due to the first winding paper 6 as much as possible. The hoisting member 2 can be made of any material other than the paper tube, but preferably has the same hardness as the flavor source 4, which improves the hoisting suitability. In addition, only the hoisting member 2 can be easily detached from the smoking article 1 by touch, so to speak, the appropriateness of detachment is also improved.

Further, in order to improve the adhesiveness of the first roll paper 6 to the first connecting body 13, the hoisting member 2 and the flavor source 4 have the same ellipticity (in other words, the restoration rate) after being deformed by applying a load. Some are preferred. Details of the reasons for improving winding suitability, detachment suitability, and adhesion suitability will be described later. The hoisting member 2 may be a hollow filter tow wrapped with a roll paper or a solid filter tow wrapped with a roll paper.
Further, the hoisting member 2 has a length in the axial direction X of preferably 5 mm to 20 mm, more preferably 10 mm to 15 mm so that the user can easily pull it out or peel it off with a finger. Thereby, the withdrawal suitability of the smoking article 1 can be enhanced.

[Heat source]
The heat source 3 is a solid material formed into a columnar shape, for example, a carbon heat source, and in the case of the present embodiment, it has a hollow portion 3a penetrating in the axial direction X. The heat source 3 burns and generates heat when ignited. By passing through the hollow portion 3a, it is possible to efficiently generate an air flow heated by the heat source 3. By passing the air heated by the heat source 3 through the flavor source 4, an aerosol containing a flavor component is efficiently generated.

[Flavor source]
The flavor source 4 is a columnar molded product, for example, a molded product obtained by molding chopped tobacco, a tobacco material into an arbitrary shape such as a granule or a sheet, a plant other than tobacco, or at least one of other flavors. It is wrapped in 4a. An aerosol-forming substrate is added to the flavor source 4.

The user sucks the aerosol generated after the airflow heated by the heat source 3 passes through the flavor source 4. As a result, the user can ingest the component of the flavor source 4. Since the flavor source 4 is formed by dividing the flavor source material 12 described later into two and both are the same material, the flavor source 4 and the flavor source material 12 may be used interchangeably in the following description.

[Filter member]
The filter member 5 is formed by arranging the tubes 10 and the filter elements 11 in a row in the axial direction X in order from the flavor source 4 side. The tube 10 is provided to rectify the airflow flowing through the smoking article 1. The tube 10 may be, for example, a paper tube or a plastic tube. The filter element 11 is, for example, an acetate filter fiber bundle wrapped with a winding paper 11a.

The filter fiber bundle may be solid or hollow. Further, particles of activated carbon or particles of hydrotalcite compounds may be added to the filter fiber bundle, or capsules filled with the content liquid may be embedded in a destructible shell. The content liquid is, for example, a perfume and an edible oil as a solvent in which the perfume dissolves. Further, the filter element 11 may be a so-called multi-segment filter in which a plurality of filter plugs are joined.

[Volume 1]
The first-rolling paper 6 is made of a paper material (including a metal-bonded paper, for example, an aluminum-bonded paper) having a relatively low air transmittance for cigarettes, and the winding member 2 is formed from the end of the first-rolling paper 6. The tip is protruding. As a result, the presence of the hoisting member 2 to be separated can be easily visually recognized.

[Volume 2]
The second roll paper 7 is made of paper having a low air permeability for cigarettes. Further, the second roll paper 7 is wound up in a region extending from the filter member 5 to a part of the flavor source 4 adjacent thereto, and the filter member 5 and the flavor source 4 are adhered to a region connectable by the second roll paper 7 (not shown). The part is formed.

Hereinafter, the manufacturing process of the smoking article 1 will be described with reference to FIGS. 2 to 8. FIG. 2 is a flowchart showing a manufacturing process of the smoking article 1, and FIGS. 3 to 8 are diagrams for explaining steps S1 to S6 shown in FIG.

[First Arrangement Step] (Step S1)
When the manufacturing process of the smoking article 1 is started, first, as shown in FIG. 3, two hoisting members 2, two heat sources 3 and one flavor source material 12 are supplied, and the hoisting member 2, The first connecting body 13 is formed by arranging the heat source 3, the flavor source material 12, the heat source 3, and the hoisting member 2 in a line in the axial direction X in this order. The flavor source material 12 has about twice the length of the flavor source 4 in the axial direction X.

Specifically, each material constituting the first connecting body 13 is supplied by a supply unit (not shown). The materials supplied from the supply unit are arranged side by side in the order shown in FIG. 3, and each material is sucked by the suction drum and is positioned at intervals at which new material can be supplied each time it reaches each section. It should be noted that the supply, arrangement, and treatment of each material required in each process may be performed in one place.

[Volume 1 Upper Process] (Step S2)
Next, as shown in FIG. 4, the first connecting body 13 is wound up by the first winding paper 6 along the axial direction X thereof to form the first continuous body 14. Specifically, a hoisting unit (not shown) having a hoisting roller is used. The first winding paper 6 is supplied to the winding unit, the first connecting body 13 is arranged on the first winding paper 6, and the first winding paper 6 is spread over the entire area of the first connecting body 13 in the axial direction X by the winding roller. Wind up while pressing substantially evenly.

At the time of this winding, the hoisting members 2 are positioned at both ends of the first connecting body 13, so that both ends of the first connecting body 13 are not crushed and the peripheral surface of the first connecting body 13 is evenly first. It can be wound evenly by the wrapping paper 6. Therefore, the winding suitability of the first connecting body 13 is improved. Further, as described above, since the hoisting roller presses the entire first connecting body 13, not only the hoisting member 2 but also the flavor source material 12 is present in the first connecting body 13. This is one of the factors for improving the hoisting suitability of the connecting body 13.

Since the heat source 3 has a slightly smaller diameter than the hoisting member 2 and the flavor source material 12, the heat source 3 does not come into contact with the hoisting roller during the hoisting. Therefore, the hardness of the heat source 3 and the like do not affect the winding properly. Then, unnecessary gaps in the first continuous body 14 wound by the first roll paper 6 and irregularities on the surface of the first continuous body 14 are suppressed, and the first continuous body satisfying the conforming quality related to the winding of the smoking article 1. Body 14 is formed.

Further, when the first connecting body 13 is wound up by the first winding paper 6, the adhesive portion 8 for adhering the first connecting body 13 and the first winding paper 6 and the hoisting member 2 of each heat source 3 At least a part of the heat source 3 and a non-adhesive portion 9 that is not adhered are formed.

More specifically, on the inner peripheral surface of the first roll paper 6 in the state of the first continuous body 14, a hoisting member 2, a part of the heat source 3, and a region continuous in the axial direction X facing the flavor source material 12 An adhesive is applied to (the entire peripheral surface or a partial peripheral surface), and the adhesive portion 8 is formed by winding the first connecting body 13 with the first winding paper 6.

On the other hand, on the inner peripheral surface of the first roll paper 6, an adhesive is applied to a region (all peripheral surfaces or a partial peripheral surface) continuous with the axial direction X facing a part of the heat source 3 and the hoisting member 2. The non-adhesive portion 9 is formed by winding the first connecting body 13 with the first winding paper 6 without coating. Then, in the smoking article 1, at least a part of the hoisting member 2 is separated by the non-adhesive portion 9, and at least a part of the heat source 3 is exposed so as to be able to be heated by ignition.

If the non-adhesive portion 9 is present, it is not necessary to form the adhesive portion 8 over the entire area on the side of the hoisting member 2. Further, it is not always necessary to project the tips of the hoisting members 2 from both ends of the first roll paper 6.

[First cutting step] (step S3)
Next, as shown in FIG. 5, the first continuous body 14 is cut into two parts by a cutter (not shown) at the portion indicated by the broken line of the flavor source material 12, and the hoisting member 2, the heat source 3, and the flavor source material 12 are divided into two parts. Two intermediate rods 15 are formed in which the flavor sources 4 thus formed are arranged in a row in the axial direction X in this order.

[Second arrangement step] (step S4)
Next, as shown in FIG. 6, the two intermediate rods 15 are separated from each other in the axial direction X, and then the filter member material 16 is supplied between the intermediate rods 15. The two intermediate rods 15 may remain in the orientation in the state of being cut in step S3, and it is not necessary to reverse the orientation. The filter member material 16 is formed of a filter element material 17 having a length about twice that of the filter element 11 in the axial direction X, and tubes 10 arranged at both ends of the filter element material 17.

The filter member material 16 may be supplied after the pipe 10, the filter element material 17, and the pipe 10 are arranged in a line in the axial direction X in this order, or the pipe 10, the filter element material 17, and the pipe 10 are individually supplied. It may be supplied as the filter element material 17 by supplying and arranging. Then, the intermediate rod 15, the filter member material 16, and the intermediate rod 15 are arranged in a row in the axial direction X in this order with the flavor source 4 side of the two intermediate rods 15 facing both ends of the filter member material 16. 2 Connect 18 is formed.

[Volume 2 Upper Process] (Step S5)
Next, as shown in FIG. 7, the second connecting body 18 is wound up with the second winding paper 7 to form the second continuous body 19. Specifically, the second roll paper 7 is supplied to the winding unit similar to the case of step S2, and the second connecting body 18 is arranged on the second roll paper 7. Then, the winding roller winds the second winding paper 7 while pressing it substantially uniformly over the continuous region from the filter member material 16 to the flavor source 4 of the two intermediate rods 15 in the axial direction X.

At the time of this winding, the flavor sources 4 are positioned at both ends of the second connecting body 18, so that the peripheral surfaces of the filter member material 16 and the flavor source 4 of the intermediate rod 15 can be uniformly wound by the second winding paper 7. it can. Therefore, the winding suitability of the second connecting body 18 is improved, and the second continuous body 19 satisfying the conforming quality related to the winding of the smoking article 1 is formed.

Further, in the second continuous body 19, at least a part of the heat source 3 of the intermediate rod 15 is projected from both ends of the second roll paper 7. As a result, it is not necessary to tear the second roll paper 7 when the hoisting member 2 is detached from the smoking article 1, so that the hoisting member 2 can be easily detached.

Further, when the second connecting body 18 is wound up with the second roll paper 7, it is appropriately bonded at an adhesive portion (not shown), whereby the connection between the filter member material 16 and the intermediate rod 15 in the second continuous body 19 is strengthened. Become.

[Second cutting step] (step S6)
Next, as shown in FIG. 8, the second continuous body 19 is cut into two parts by cutting with a cutter (not shown) at the portion indicated by the broken line of the filter member material 16, and the hoisting member 2, the heat source 3, the flavor source 4, and the filter member are divided. Two smoking articles 1 are formed by arranging the filter members 5 formed by dividing the material 16 in two in a row in the axial direction X in this order. As a result, the manufacturing process of the smoking article 1 is completed.

FIG. 9 shows a state in which the hoisting member 2 is detached from the smoking article 1. When the user pulls the hoisting member 2 in the axial direction X when using the smoking article 1, the first roll paper 6 is torn in the circumferential direction at the non-adhesive portion 9, and the hoisting member 2 is torn from the smoking article 1. It can be detached by peeling it off. As a result, as shown in FIG. 9, the heat source 3 is exposed at the tip of the smoking article 1, and the heat source 3 can be ignited. In addition, a step of detaching the hoisting member 2 may be provided in the manufacturing process of the smoking article 1, and the smoking article 1 after the hoisting member 2 is detached may be treated as a finished product.

Here, when the hoisting member 2 is detached from the smoking article 1, in order to ensure that only the hoisting member 2 is detached from the smoking article 1 at the non-adhesive portion 9, the user feels the touch with a finger. I often rely on it. That is, when using the smoking article 1, if it is difficult to determine the presence of the hoisting member 2 and, by extension, the boundary between the hoisting member 2 and the heat source 3 (that is, the position of the non-adhesive portion 9) by touch, the user winds up. Not only the upper member 2 but also the heat source 3 may be separated together, or the intermediate rod 15 including the flavor source 4 may be separated.

Therefore, in the present embodiment, the smoking article 1 is further improved in the above-mentioned hoisting suitability, and the smoking article 1 is provided with a detachment suitability that allows only the hoisting member 2 to be easily detached from the smoking article 1 by touch. In order to do so, the hardness evaluation step of the smoking article 1 is performed.
Hereinafter, the hardness evaluation process will be described with reference to the flowchart showing the hardness evaluation process of FIG.

[Hardness measurement] (step S11)
When the hardness evaluation step is started, first, the hardness of the hoisting member 2, the heat source 3, and the flavor source material 12 is measured.
FIG. 11 shows a side view of the hardness measuring unit 20 used for hardness measurement.

The hardness measuring unit 20 includes a base 21, a pair of support walls 22, two lower rods 23, two upper rods 24, an elevator 25, and the like. The pair of support walls 22 are erected parallel to the base 21 and extend in the depth direction of FIG. The two lower rods 23 are solidified on the base 21 between the pair of support walls 22 and extend parallel to the pair of support walls 22. The two upper rods 24 are arranged so as to face the upper side of the two lower rods 23, and are supported by the elevator 25 so as to be able to move up and down.

First, any one of the hoisting member 2, the heat source 3, and the flavor source material 12 (hereinafter, also referred to as measurement target A) is placed over the paired support wall 22 and the lower rod 23, respectively. By arranging a large number of measurement targets A along the extending direction of the support wall 22 and the lower rod 23, it is possible to measure the hardness of a large number (for example, 20) of measurement targets A at a time. Since the flavor source 4 after dividing the flavor source material 12 into two has the same hardness as the flavor source material 12, the smoking article 1 itself and the flavor source 4 constituting the smoking article 1 may be used as the measurement target A.

Next, when the elevator 25 is operated to lower the upper rod 24 in the direction of the arrow in FIG. 11, the measurement target A is sandwiched between the upper rod 24 and the lower rod, and a load is applied to the measurement target A. .. By shifting the measurement target A in the axial direction X, a load can be applied to a desired position of the measurement target A. When measuring the hardness of the measurement target A, it is preferable to apply a load to the central portion of the measurement target A in the longitudinal direction.

The hardness measurement is performed based on the average value of the deformation amounts of the individual measurement targets A when a load of 19.6 N is continuously applied to the 20 measurement targets A for 20 seconds.
In FIG. 12, the cross-sectional shape of the measurement target A before the load F is applied is shown by a chain line, and the cross-sectional shape of the measurement target A when the load F is applied is shown by a solid line. The measurement target A has a circular cross section and an initial height H1 (= the diameter of the measurement target A) before the load F is applied, and has an elliptical cross section and a balance H2 when the load F is applied. ..

In the present embodiment, the hardness of the measurement target A is calculated based on the following equation.
-Hardness (%) = (H2 / H1) x 100
According to this formula, the hardness of each measurement target A is measured based on the ratio (percentage) of the balance H2 to the initial height H1. Then, in this evaluation, the average value of the hardness of the 20 measured objects A is calculated, and this average value is used as the hardness of the measurement object A, that is, the hoisting member 2, the heat source 3, and the flavor source material. It is defined as any hardness of 12. The same shall apply hereinafter.

The smaller the difference (ΔH) obtained by subtracting the balance H2 from the initial height H1, the larger the value of hardness, and it is determined that the measurement target A is hard. When the heat source 3 is a carbon heat source and the hardness is specified using the measurement target A as the carbon heat source, the balance H2 becomes equal to the initial height H1, and the measured value of the hardness is 100%. Therefore, the hardness of the heat source 3 is defined as 100%, and the following description will be given.

Then, in order to improve both the winding suitability and the detachment suitability, when the hardness Hh of the heat source is defined as 100% by the experiment of the inventor, the hardness Hw of the hoisting member 2 and the flavor source material 12 The preferred numerical value of the hardness Hf of is 60% or more and 95% or less, more preferably 65% or more and 80% or less, and further preferably the hardness Hw and flavor of the hoisting member 2. It has been found that the numerical difference between the hardness Hf of the source material 12 and the hardness Hf is 30% or less, and more preferably, the numerical difference between the hardness and the hardness Hf is 15% or less. Therefore, in the present embodiment, the hardness is evaluated by performing at least one of the following steps S12 to S14.

[First hardness determination] (step S12)
As shown in FIG. 10, when the hardness Hh of the heat source 3 is defined as 100%, the hardness Hw of the hoisting member 2 and the hardness Hf of the flavor source material 12 are 60% or more and 95% or less. Determine if it exists. When the determination result is Yes, the difference in hardness ((Hh-Hw) and (Hh-Hf)) between the heat source 3 and the hoisting member 2 adjacent to both sides of the smoking article 1 and the flavor source material 12 is to some extent. Is present, so that the required hoisting suitability can be ensured, and the hoisting member 2 and the flavor source material 12 are softer than the heat source 3, and the user can make a boundary between the hoisting member 2 and the heat source 3. Since it is easy to recognize by tactile sensation, it is determined that the required withdrawal suitability can be secured, and the process proceeds to step S15 to obtain acceptance permission, and then the present process is terminated.

On the other hand, when the determination result is NO, the hoisting member 2 and the flavor source material 12 are too soft to ensure proper hoisting, or the hoisting member 2 and the flavor source material 12 are as hard as the heat source 3. Since there is a risk that the hoisting member 2 and the heat source 3 may be separated from each other, or the intermediate rod 15 may be separated from each other, it is determined that the appropriateness of the detachment cannot be ensured. finish.

[Second hardness determination] (step S13)
When the hardness Hh of the heat source 3 is defined as 100%, it is determined whether or not the difference between the hardness Hw of the hoisting member 2 and the hardness Hf of the flavor source material 12 is 30% or less. When the determination result is Yes, the difference in hardness (| Hw-Hf | (absolute value)) between the hoisting member 2 and the flavor source material 12 is relatively small, so the hoisting member 2 and the flavor source material 12 As the hardness of the hoisting member approaches, the hoisting suitability is further improved, and the hardness of the heat source 3 sandwiched between the hoisting member 2 and the flavor source 4 is further emphasized. Since the boundary with the heat source 3 is more easily recognized by tactile sensation, it is determined that the appropriateness of withdrawal is further improved, and the process proceeds to step S15 to grant acceptance permission, and then the present step is terminated.

On the other hand, when the determination result is NO, the difference in hardness between the hoisting member 2 and the flavor source material 12 is too large to ensure proper hoisting, or the hoisting member 2 or the flavor source material 12 is the heat source 3. If there is a difference in hardness due to being as hard as the above, it is determined that the hoisting member 2 and the heat source 3 may be separated or the intermediate rods 15 may be separated from each other, and the appropriate removal cannot be ensured. After moving to step S16 and rejecting the acceptance, the present process is terminated.

[Third hardness determination] (step S14)
When the hardness Hh of the heat source 3 is defined as 100%, it is determined whether or not the difference between the hardness Hw of the hoisting member 2 and the hardness Hf of the flavor source material 12 is 15% or less. When the determination result is Yes, the difference in hardness (| Hw-Hf |) between the hoisting member 2 and the flavor source 4 is even smaller, so that the hardness between the hoisting member 2 and the flavor source material 12 is further increased. By getting closer, the hoisting suitability is further improved, and the hardness of the heat source 3 sandwiched between the hoisting member 2 and the flavor source 4 is further emphasized, so that the user can use the hoisting member 2 and the heat source 3 Since it is easier to recognize the boundary of the above by tactile sensation, it is determined that the appropriateness of withdrawal is further improved, and the process proceeds to step S15 to grant acceptance permission, and then the present step is terminated.

On the other hand, when the determination result is NO, the hardness of the hoisting member 2 and the flavor source 4 is slightly too large to ensure proper hoisting, or the hoisting member 2 and the flavor source 4 are separated or intermediate. It is determined that the possibility that each rod 15 may be detached cannot be eliminated and the appropriateness of detachment cannot always be ensured, and the process proceeds to step S16 to reject acceptance, and then the present process is terminated.

Here, in order to evenly bond the first connecting body 13 and the first winding paper 6 at the bonding portion in the first winding step described above, the compressive strength of the winding member 2 and the flavor source material 12 is important. is there. In the manufacturing process of smoking articles, the hoisting member 2 and the flavor source material 12 may be crushed in the manufacturing process, and the hoisting member 2 and the flavor source material 12 may be crushed in the first winding. This is because when the step is performed, not only the winding suitability is deteriorated, but also a gap is formed in the adhesive portion 8 to cause poor adhesion of the first connecting body 13 and the smoking article 1.

Therefore, in the present embodiment, the smoking article 1 is further improved in winding suitability, and the first connecting body 13 and the first roll paper 6 in the adhesive portion 8 are properly bonded to each other. The restoration rate evaluation step of the smoking article 1 is performed in order to impart to the smoking article 1.
Hereinafter, the restoration rate evaluation process will be described with reference to the flowchart showing the restoration rate evaluation process of FIG.

[Restoration rate measurement] (step S21)
When the restoration rate evaluation step is started, first, the restoration rate of the hoisting member 2 and the flavor source material 12 is measured.
FIG. 14 shows a side view of the restoration rate measuring unit 30 used in the restoration rate measurement.

The restoration rate measuring unit 30 includes a base 31, a disk 32, an elevator 33, and the like. The circular surface of the disk 32 is arranged toward the base 31, and is supported by the elevator 33 so as to be able to move up and down.

First, the hoisting member 2 or the flavor source material 12 (hereinafter, also referred to as measurement target B) is placed on the base 31, and then the elevator 33 is operated to lower the disk 32 as shown in FIG. The target B is sandwiched between the disk 32 and the base 31, and a load is applied to the measurement target B. Since the flavor source 4 after dividing the flavor source material 12 into two has the same restoration rate as the flavor source material 12, the flavor source 4 may be used as the measurement target B.

The restoration rate measurement is performed based on the ellipticity when the measurement target B is subjected to a load for compressing the measurement target B to 1/2 of the diameter for 1 minute and then left for 5 minutes.
In FIG. 15, the cross-sectional shape of the measurement target B before the load F is applied is shown by a chain line, and the cross-sectional shape of the measurement target B immediately after the load F is applied and left is shown by a solid line.

The measurement target B has a substantially circular cross section before the load F is applied, and immediately after the load F is applied and left to stand, the measurement target B has an elliptical cross section and has a major axis Da and a minor axis Db.
In the present embodiment, the ellipticity of the measurement target B is calculated based on the following equation.
-Ellipticity (%) = 2 (Da-Db) / (Da + Db) x 100
According to this equation, it is determined that the smaller the difference obtained by subtracting the minor axis Db from the major axis Da, the smaller the numerical value of the ellipticity, and the larger the restoration rate of the measurement target B.

Then, in order to improve both the winding suitability and the bonding suitability, the inventor's experiment shows that the ellipticity Ew of the hoisting member 2 and the ellipticity Ef of the flavor source material 12 are preferably 40% or less. Yes, more preferably, the numerical difference between the ellipticity Ew of the hoisting member 2 and the ellipticity Ef of the flavor source material 12 is 30% or less, and more preferably, the numerical difference of the ellipticity is 15% or less. It turns out that there is. Therefore, in the present embodiment, the ellipticity evaluation is performed by performing at least one of the following steps S22 to S24.

[Determination of first ellipticity] (step S22)
As shown in FIG. 13, it is determined whether or not the ellipticity Ew of the hoisting member 2 and the ellipticity Ef of the flavor source material 12 are 40% or less. When the determination result is Yes, the restoration rate of the hoisting member 2 and the flavor source material 12 is relatively large, so that the required hoisting suitability can be ensured, and the adhesive portion 8 in the first hoisting process It is determined that the first connecting body 13 and the first roll paper 6 can be adhered evenly, and the process proceeds to step S25 to allow acceptance, and then the present process is terminated.

On the other hand, when the determination result is NO, the recovery rate of the hoisting member 2 and the flavor source material 12 is small, so that the hoisting suitability cannot be ensured, or the hoisting member 2 or the flavor source material 12 generated in the manufacturing process. It is determined that the proper adhesion cannot be ensured because the dent of the above causes a non-adhesive region in the adhesive portion 8 or the first roll paper 6 is likely to be peeled off in the adhesive portion 8, and the process proceeds to step S26 to reject acceptance. After that, this process is completed.

[Determination of second ellipticity] (step S23)
Next, it is determined whether or not the difference between the ellipticity Ew of the hoisting member 2 and the ellipticity Ef of the flavor source material 12 is 30% or less. When the determination result is Yes, the difference in ellipticity (| Ew-Ef | (absolute value)) between the hoisting member 2 and the flavor source material 12 is relatively small, so the hoisting member 2 and the flavor source material 12 It is determined that the winding suitability is further improved as the restoration rate approaches the above, and the bonding suitability is further improved because the bonding mode between the winding member 2 and the flavor source material 12 in the bonding portion 8 is unlikely to occur. Then, after moving to step S25 and granting acceptance permission, this step is terminated.

On the other hand, when the determination result is NO, the difference in restoration rate between the hoisting member 2 and the flavor source material 12 is too large to ensure proper hoisting, or the hoisting member 2 and the flavor source material in the adhesive portion 8 are not secured. It is determined that the appropriateness of adhesion cannot be ensured due to the difference in the bonding mode with 12 due to the difference in the bonding mode, and the process proceeds to step S26 to reject acceptance, and then the present step is terminated.

[Determination of third ellipticity] (step S24)
Next, it is determined whether or not the difference between the ellipticity Ew of the hoisting member 2 and the ellipticity Ef of the flavor source material 12 is 15% or less. When the determination result is Yes, the difference in ellipticity (| Ew-Ef |) between the hoisting member 2 and the flavor source material 12 is even smaller, so that the restoration rate between the hoisting member 2 and the flavor source material 12 is high. Further, the winding suitability is further improved by getting closer, and the bonding suitability is further improved because the difference in the bonding mode between the winding member 2 and the flavor source material 12 in the bonding portion 8 is less likely to occur. After the determination is made, the process proceeds to step S25 to obtain acceptance permission, and then this step is terminated.

On the other hand, when the determination result is NO, the restoration rate of the hoisting member 2 and the flavor source material 12 is slightly too large to ensure proper hoisting, or the adhesion between the hoisting member 2 and the flavor source material 12 is poor. It is determined that the appropriateness of adhesion cannot always be ensured because the risk of causing the problem cannot be eliminated, and the process proceeds to step S26 to reject acceptance, and then the present process is terminated.

As described above, in the present embodiment, by manufacturing the smoking article 1 by the steps S1 to S6, the smoking article 1 can be manufactured using the segment (constituent member) having a long segment length and a large aspect ratio. it can. Therefore, at the time of manufacturing, it is not necessary to strictly control the posture of the segment in order to suppress the rolling of the segment, and it is not necessary to prepare the equipment for that purpose, so that the quality and productivity of the smoking article 1 can be improved. Both can be realized.

Further, in the first cutting step, the first continuous body 14 is cut in the flavor source material 12 and divided into two to form two intermediate rods 15, and in the second cutting step, the second continuous body 19 is cut into the filter member material 16. Cut in half to form two smoking articles 1. Therefore, by dividing the bilaterally symmetric continuum in the axial direction X into two to form the same member, a large number of pre-cut or molded small segments are individually supplied to form a connecting body and thus a continuous body. Compared with the case of producing the smoking article 1, the smoking article 1 can be efficiently produced, and the productivity of the smoking article 1 is improved.

Further, in the series of steps S1 to S6, the hoisting member 2 is always positioned at both ends of the connecting

bodies

13 and 18, the intermediate rods 15, and the

continuous bodies

14 and 19. In particular, when the first connecting body 13 is wound up by the first winding paper 6 when forming the first continuous body 14, the hoisting members 2 are positioned at both ends to improve the hoisting suitability of the smoking article 1. It is possible to further improve the quality of the smoking article 1.

Further, in the first winding step, the adhesive portion 8 for adhering the first connecting body 13 and the first winding paper 6 and at least a part of the heat source 3 are adhered to each of the hoisting members 2 of each heat source 3. A non-adhesive portion 9 that is not formed is formed. As a result, at least a part of the hoisting member 2 can be separated by the non-adhesive portion 9, and at least a part of the heat source 3 can be exposed and used by being able to be heated by ignition.

Further, by performing the hardness evaluation step described above, the hoisting suitability of the smoking article 1 can be further improved, and the smoking article 1 can be given the withdrawal suitability. Specifically, in the hardness evaluation step, the ratio of the balance H2 to the initial height H1 when a load of 19.6 N is continuously applied to the hoisting member 2, the heat source 3, and the flavor source material 12 for 20 seconds. Based on this, these hardnesses are measured. Then, by performing the first hardness determination, the hoisting member 2 and the flavor source material 12 are softer than the heat source 3, and the user can easily recognize the boundary between the hoisting member 2 and the heat source 3 by touch. Only those that can ensure proper withdrawal will be given permission to accept.

Further, by performing the second and third hardness determinations, the hoisting member 2 and the flavor source material 12 are closer to each other in hardness, so that the hoisting suitability is further improved, and in the smoking article 1, The hardness of the heat source 3 sandwiched between the hoisting member 2 and the flavor source 4 is further emphasized, and the user can more easily recognize the boundary between the hoisting member 2 and the heat source 3 by tactile sensation. Only those that are further improved will be accepted. In addition, instead of performing all the determinations of the first to third hardness determinations, at least one of the determinations may be performed, or the first to third hardness determinations may be sequentially performed. good. Even in this case, the appropriateness of hoisting and withdrawal of the smoking article 1 is improved.

Further, by performing the restoration rate evaluation step described above, the hoisting suitability of the smoking article 1 can be further improved, and the adhesive suitability can be imparted to the smoking article 1. Specifically, the restoration rate evaluation step is based on the ellipticity of the hoisting member 2 and the flavor source material 12 when a load for compressing to 1/2 of the diameter is applied for 1 minute and then left for 5 minutes. Measure the recovery rate. Then, by performing the first ellipticity determination, the hoisting member 2 and the flavor source material 12 have a relatively large restoration rate, so that the required hoisting suitability can be ensured and the first hoisting is performed. In the process, only those having an adhesive suitability capable of adhering the first connecting body 13 and the first roll paper 6 in the adhesive portion 8 without bias are given acceptance permission.

Further, by performing the second and third ellipticity determinations, the hoisting member 2 and the flavor source material 12 are closer to each other in the restoration ratio, so that the hoisting suitability is further improved, and the adhesive portion 8 is further improved. Only those whose adhesion suitability is further improved by making it more difficult for the difference in the bonding mode between the hoisting member 2 and the flavor source material 12 to occur in the above are issued. In addition, instead of performing all the determinations of the first to third ellipticity determinations, at least one of the determinations may be performed, or the first to third ellipticity determinations may be sequentially performed. good. Even in this case, the appropriateness of winding and adhering the smoking article 1 is improved.

As described above, the smoking article 1 of the present embodiment not only improves the hoisting suitability by providing the hoisting member 2, but also improves the hoisting suitability by evaluating the hardness of the hoisting member 2 and the flavor source material 12. Further improvement and detachment suitability are aimed at, and further improvement of hoisting suitability and adhesion suitability are aimed at by evaluating the restoration rate of the hoisting member 2 and the flavor source material 12.

Although the description of the embodiment of the present invention is completed above, the present invention is not limited to these, and various modifications can be made without departing from the spirit of the present invention.
For example, the smoking article 1 produced by the above embodiment has a more preferable form, and is not limited to the above-mentioned structure. Therefore, other aspects of the smoking article 1 to which the above-mentioned method for producing the smoking article 1 can be applied will be described below.

<Second Embodiment>
As shown in the smoking article 1 of FIG. 16 (only the intermediate rod 15 is partially shown), the outer peripheral surface 6a of the first roll paper 6 when wound up with respect to the first connecting body 13 is coated with a pigment such as calcium carbonate. It is an uncoated surface that has not been coated. Further, the first roll paper 6 is preferably a high-density paper having a basis weight in the range of 70 g / m2 to 140 g / m2. The first rolling paper 6 having such a basis weight range may be a metal-bonded paper, for example, an aluminum-bonded paper as described above.

By making the outer peripheral surface 6a of the first roll paper 6 a non-coated surface with the paper material exposed, the production cost of the smoking article 1 can be reduced. Further, by using the first roll paper 6 as a high-density paper, the charring of the first roll paper 6 when the heat source 3 is heated while using the smoking article 1 is suppressed, and the tensile strength of the first roll paper 6 is appropriate. Is given, and the connection of the segments by the first roll paper 6 is strengthened. As a result, the quality of the smoking article 1 is further improved.

<Third Embodiment>
As shown in the smoking article 1 of FIG. 17 (only the intermediate rod 15 is partially shown), the non-adhesive portion 9 is a thin portion 6c in which the thickness of the first roll paper 6 is thinner than that of the adhesive portion 8. The thickness of the thin portion 6c is, for example, 1/2 or less of the thickness of the first roll paper 6. As a result, the hoisting member 2 is easily detached from the non-adhesive portion 9, so that the appropriateness of detaching the smoking article 1 is further improved.

<Fourth Embodiment>
As shown in the smoking article 1 of FIG. 18 (only the intermediate rod 15 is partially shown), the heat conductive element 40 is inside the inner peripheral surface 6b of the first roll paper 6 when wound up with respect to the first connecting body 13. Is placed. The heat conductive element 40 is arranged in the region from the hoisting member 2 to the flavor source 4 via the heat source 3 in the axial direction X, and is arranged over the hoisting members 2 at both ends in the first continuous body 14. Will be done.

In this case, the first roll paper 6 may be an aluminum laminated paper in which the heat conductive element 40 is bonded to the paper material and integrated. Such an aluminum laminated paper may have two layers of paper and aluminum (in this case, the outer peripheral side at the time of winding is paper), or may be three layers of paper, aluminum, and paper. Further, when the first roll paper 6 is an aluminum laminated paper, it is preferable that the aluminum does not exist at the center position of the flavor source 4 in the axial direction X. The absence of aluminum in the central portion has the advantage that the first continuum 14 can be easily cut in the first cutting step.

It should be noted that the first continuum 14 may be arranged over the two flavor source materials 12. The heat conductive element 40 can be made of any material, but a metal foil (for example, an aluminum foil) is preferable. By arranging the heat conductive element 40, heat transfer from the heat source 3 to the flavor source 4 is promoted, so that the aerosol can be generated more efficiently from the flavor source 4.

<Fifth Embodiment>
FIG. 19 shows a plan view of the first roll paper 6 unfolded and viewed from the side of the inner peripheral surface 6b. A metal foil 41 (for example, an aluminum foil) as a heat conductive element 40 is bonded to the inner peripheral surface 6b of the first roll paper 6, and the first roll paper 6 constitutes the metal bonded paper. The metal foil 41 is attached to the first winding paper 6 at three locations in the center of the winding direction Y, excluding both ends 42 in the winding direction Y. The three metal foils 41 are arranged so as to be separated from the two straight portions 43 extending in the winding direction Y over the two end portions 42. That is, the two end portions 42 and the two straight portions 43 are formed of a paper material.

FIG. 20 shows a cross-sectional view of the first continuous body 14 when the first roll paper 6 which is a metal bonded paper is used. The two straight portions 43 made of only the paper material are formed at a portion corresponding to the non-adhesive portion 9, that is, the metal foil 41 is bonded except for a portion corresponding to at least the non-adhesive portion 9 on the inner peripheral surface 6b. To. As a result, the hoisting member 2 can be easily detached at each straight portion 43, and the appropriate detachment of the smoking article 1 can be ensured.

On the other hand, the adhesive portion 8 is formed at both end portions 42 of the inner peripheral surface 6b, that is, a portion excluding the metal foil 41. As a result, the adhesiveness of the first roll paper 6 is improved and the adhesiveness of the smoking article 1 is improved as compared with the case where the adhesive is applied to the metal foil 41 to form the adhesive portion 8. Further, the metal foil 41 as the heat conductive element 40 is bonded to the inner peripheral surface 6b and integrated, so that the first roll paper 6 is processed (formation of weakening lines such as perforations) to improve the detachment suitability. Even if the outer peripheral surface 6a can be formed flat, the aesthetic appearance of the smoking article 1 can be improved while improving the productivity of the smoking article 1.

<Sixth Embodiment>
As shown in the smoking article 1 of FIG. 21 (only the intermediate rod 15 is partially shown), the hoisting member 2 is composed of two

separators

2a and 2b that can be separated by the non-adhesive portion 9. .. The separator 2a is located at the tip of the hoisting member 2 and is provided to secure a predetermined length of the hoisting member 2 in the axial direction X, and has a function of mainly improving the hoisting suitability. Therefore, the separated body 2a is arranged in the non-adhesive portion 9, can be removed after the first winding step of the manufacturing process of the smoking article 1, and does not have to be present in the completed smoking article 1.

Since the adhesive portion 8 is a thin layer of about 1 to 2 μm, the gap between the separator 2a and the first roll paper 6 as shown in FIG. 21 is very small. Therefore, when the separator 2a is wound up by the first roll paper 6, it is locked to the first roll paper 6 by friction and does not easily fall off.

On the other hand, the separated body 2b mainly has a function of protecting the heat source 3, and is detached when the user uses the smoking article 1. Therefore, the adhesive portion 8 is formed in the region where the separator 2b of the first roll paper 6 is arranged. By forming the hoisting member 2 from the two separating

bodies

2a and 2b and separating the functions in this way, the degree of freedom in designing the smoking article 1 can be increased.

Further, as shown in FIG. 22, the hoisting member 2 may be provided with a connecting portion 2c for connecting the separated

bodies

2a and 2b. This makes it possible to prevent the separator 2a from falling off unintentionally. The number of connecting portions 2c is preferably 1 or 2 so that the separated body 2a can be easily removed.

<7th Embodiment>
As shown in the smoking article 1 of FIG. 23 (only the intermediate rod 15 is partially shown), the first roll paper 6 has a vent 6d that allows ventilation from the vicinity of the heat source 3 to the flavor source 4. Such ventilation holes may be provided on the outer peripheral side of the flavor source 4. Further, the heat source 3 may be formed by solidifying a granular material other than carbon as long as it burns and generates heat by ignition, and may not have the hollow portion 3a as shown in FIG. 23.

Further, the heat source 3 is not limited to a solid material, and may be used by winding a sheet-shaped material. Even when the hollow portion 3a is not provided, ventilation air can be generated from the ventilation hole 6d through the heat source 3 to the flavor source 4. Both the hollow portion 3a and the ventilation hole 6d may be provided. Further, the hollow portion 3a is not limited to a hole penetrating in the axial direction X, and may be a hole formed in the peripheral surface of the heat source 3. Further, when at least one of the hollow portion 3a and the ventilation hole 6d is provided, the heat transfer efficiency is increased, so that the heat conductive element 40 may not be required.

<8th Embodiment>
As shown in the smoking article 1 of FIG. 24, the filter member 5 is formed by arranging the pipe 10, the cooling element 50, and the filter element 11 in a line in the axial direction X in order from the flavor source 4 side. The cooling element 50 is, for example, a folded sheet of paper, a biodegradable polymer, or the like wrapped with a winding paper 50a. In this case, the airflow that has passed through the heat source 3 and the flavor source 4 in this order is cooled by the cooling element 50, and the aerosol generation efficiency is further improved.

Further, in the case of FIG. 24, the cooling element 50 and the filter element 11 are dual segment attachments 52 integrally wrapped with a winding paper 51. As a result, since the filter member material 16 is composed of only two members, the pipe 10 and the dual segment attachment 52, the handleability of the members in the second arrangement step is improved, and the productivity of the filter member 5 and the smoking article 1 is improved. Is improved.

<9th embodiment>
As shown in the smoking article 1 of FIG. 25, the filter member 5 is formed by arranging the pipe 10, the cooling element 50, and the filter element 11 in a row in the axial direction X in order from the flavor source 4 side, and these are formed by the winding paper 51. It is a triple segment attachment 53 that is integrally wrapped with. As a result, since the filter member material 16 is composed of only one member of the triple segment attachment 53, the handleability of the members in the second arrangement step is further improved, and the productivity of the filter member 5 and thus the smoking article 1 is further improved. improves.

The method for producing the smoking article 1 described above can be applied to the smoking article 1 produced by each of the above embodiments alone or in combination.
