In the present embodiment, the take-up unit 26 is rotationally driven by driving a motor or the like, and all other rollers are driven rollers. However, the feeding method is not limited to this, and for example, some of the driven rollers in the middle may be used as driving rollers, and the base material 16 may be positively fed in the feeding direction by the driving rollers.

A base material 16 is wound around the core portion of the feeding portion 25, from which the base material 16 can be fed out. The base material 16 is wound around the core portion in the winding portion 26, and by rotationally driving the base material 16, the base material 16 can be wound up together with the fragrance-containing sheet 12 and collected.

The drying mechanism 24 has, for example, four drying chambers 24A to 24D. The base material 16 is passed through the four drying chambers 24A to 24D. Each drying chamber 24A is provided with a plurality of blower nozzles 31. In the drying chamber 24A, the fragrance-containing sheet 12 provided on the base material 16 and having the slits 22 formed can be dried by blowing warm air at 70 to 100 ° C. from the air blowing nozzle 31. The temperature conditions of the four drying chambers 24A may be common to each other, or the temperature conditions may be different from each other for each drying chamber 24A.

The molding mechanism 17 is configured to be able to mold the fragrance-containing sheet 12 before gelling. The molding mechanism 17 has a comma roll 32 (comma roller, fixed roller) and a coating roll 33 (coating roller, rotary roller) facing the comma roll 32. As shown in FIGS. 2 and 5, the coating roll 33 is formed in a cylindrical shape. The coating roll 33 has an outer peripheral surface 34 and a recess 35 provided in a substantially intermediate portion in the axial direction and recessed from the outer peripheral surface. The recess 35 has a pair of tapered portions 36 and a small diameter portion 37 located between the pair of tapered portions 36. The small diameter portion 37 is formed, for example, at a depth of 10 to 100 μm from the outer peripheral surface 34, preferably 20 to 80 μm from the outer peripheral surface 34, and more preferably 40 to 60 μm from the outer peripheral surface 34. It is formed by the diameter. The coating roll 33 is a so-called driven roller, and is rotated together with the base material 16 along the feeding direction A. The coating roll 33 is formed by, for example, machining (cutting, lathe) or the like.

As shown in FIGS. 2 and 5, the comma roll 32 has a cross-sectional shape of a so-called English punctuation mark "comma", and is a cylindrical shape with a notch formed by cutting out a part of the cylindrical shape. Is doing. The comma roll 32 is fixedly provided and cannot rotate around its central axis.

As shown in FIG. 5, the molding mechanism 17 further has a first gap 17A and a second gap 17B between the comma roll 32 and the coating roll 33. The first gap portion 17A is provided at a substantially central portion in the width direction W of the fragrance-containing sheet 12. The second gap portion 17B is provided at one end of the fragrance-containing sheet 12 before gelation in the width direction W. In the present embodiment, the second gap portion 17B is provided in pairs on both sides of the first gap portion 17A, but may be provided only on one side adjacent to the first gap portion 17A.

The first gap portion 17A corresponds to the small diameter portion 37 and the pair of tapered portions 36. The second gap 17B corresponds to the outer peripheral surface 34. Therefore, the gap dimension (height dimension) H2 of the second gap portion 17B is smaller than the gap dimension (height dimension) H1 of the first gap portion 17A.

As shown in FIGS. 2 and 7, the slit forming portion 23 has one or more slit forming parts 38 and one or more holding portions 41 for holding one or more slit forming parts 38. One slit forming component 38 can form one slit 22. Each of the slit-forming components 38 can form a slit 22 having a depth corresponding to all or a part of the thickness of the perfume-containing sheet 12 along the feeding direction A of the perfume-containing sheet 12. Therefore, each of the slits 22 extends continuously along the feeding direction A of the perfume-containing sheet 12.

In the present embodiment, it is preferable that one or more slit forming parts 38 are provided in two, that is, in a pair. It is preferable that one of the pair of slit-forming parts 38 is provided so as to be located near one end of the fragrance-containing sheet 12 in the width direction W, and the other of the pair of slit-forming parts 38 is the fragrance-containing sheet 12. It is preferable that it is provided so as to be located in the vicinity of the other end portion in the width direction W of the above. As shown in FIG. 3, the slit-forming component 38 has a rounded tip and is shaped so as not to damage the base material 16. From the viewpoint of reusing the base material 16, it is preferable to use the slit-forming component 38 having such a roundness. As the slit forming component 38, for example, a blade such as a pallet knife made of a stainless steel material or the like can be preferably used. The slit-forming component 38 may be any as long as it forms a slit in the fragrance-containing sheet 12 (polysaccharide sheet) and does not damage the base material 16 (base sheet). The slit forming component 38 is not limited to the palette knife, and may be, for example, a spatula, a plate-shaped object, or the like. Alternatively, the slit forming component 38 is a disk-shaped rotary cutter or the like, the tip of which is rounded so as not to damage the base material 16, and the weight of the cutter can be applied to the fragrance-containing sheet 12. Of course, it may be a thing.

The thickness of the slit-forming component 38 is preferably, for example, 0.1 to 2 mm, more preferably 0.3 to 1 mm so that a predetermined strength can be maintained. The slit forming component 38 does not form a cutting edge perpendicular to the feed direction at a position in contact with the perfume-containing sheet 12 on the upstream side of the feed direction, but is oblique to the feed direction (slit). It is preferable to provide a cutting edge in which the slit forming component 38 is slanted so as to taper toward the tip end side of the forming component 38. When the slit forming component 38 is particularly thick, it is particularly preferable to have the above configuration. This makes it possible to prevent the chips of the fragrance-containing sheet 12 from accumulating on the cutting edge.

The slit-forming component 38 preferably has a shape that is not sharp on the base sheet 16 (base sheet) side from the viewpoint of not damaging the base material 16. On the other hand, the slit forming component 38 preferably has a sharp shape on the side of the fragrance-containing sheet 12. This is because it is possible to prevent the chips of the fragrance-containing sheet 12 from accumulating on the cutting edge of the slit-forming component 38, or the slit-forming component 38 from being broken due to the chips or the like.

As shown in FIG. 7, one or more slit-forming parts 38 are located at positions separating the fragrance-containing sheet 12 formed in the second gap 17B and the fragrance-containing sheet 12 formed in the first gap 17A. It will be provided. The number of the slit forming parts 38 provided in the slit forming portion 23 is not limited to two, and may be three or more, or may be one. The number of holding portions 41 is, for example, the same as the number of slit forming parts 38. The holding portion 41 may be composed of one holding portion 41, or a plurality of slit-forming parts 38 may be held by one holding portion 41.

Each of the holding portions 41 has, for example, a cylindrical or U-shaped holding tool, and the handle portion of the slit forming component 38 is fitted into the holding tool with play. Therefore, the holder surrounds the handle portion of the slit-forming component 38 to prevent the slit-forming component 38 from tipping over, but the slit-forming component 38 is viewed from above with respect to the base material 16 and the fragrance-containing sheet 12. The slit forming component 38 is held so as to act on its own weight. The method of holding the slit-forming component 38 is arbitrary, and any holding method may be used as long as the structure is such that the weight of the slit-forming component 38 is applied to the fragrance-containing sheet 12. For example, in a state where the slit-forming component 38 is suspended from above by a string, the fragrance-containing sheet 12 abuts on the tip of the slit-forming component 38, and the fragrance-containing sheet 12 is subjected to its own weight by the fragrance-containing slit-forming component 38. Of course, it may be a configuration that pushes it all the way out.

The weight of the slit forming component 38 is, for example, 10 to 400 g, preferably 20 to 200 g. Therefore, the gelled fragrance-containing sheet 12 passing under the slit-forming component 38 can be pressed from above and separated. It is preferable that the slit-forming component 38 has its own weight to such an extent that the base material 16 is not significantly dented or the base material 16 is not cut when its own weight is applied. Naturally, the depth of the slit 22 can be changed by using the slit-forming component 38, which has a different weight from the stainless steel slit-forming component, or by changing the slit-forming component 38 to a resin one. .. In the present embodiment, the slit 22 having a depth corresponding to the entire thickness of the fragrance-containing sheet 12 is formed, but by changing the type of the slit-forming component 38, one of the thicknesses of the fragrance-containing sheet 12 is formed. It is also possible to form a slit 22 having a depth corresponding to the portion.

In this case, although the slit 22 is formed in the fragrance-containing sheet 12, the slit 22 is not completely separated. The depth of the slit 22 is preferably, for example, 60% or more, more preferably 75% or more, and more preferably 90% with respect to the thickness dimension of the fragrance-containing sheet 12. Most preferably, the length corresponds to% or more.

A pair of slits 22 are formed at a position of 6 mm.

The fragrance-containing sheet 12 has a width (length) of 500 mm and a thickness of 350 to 1300 μm in the width direction W, for example, in the state before drying. In the dried state, the fragrance-containing sheet 12 has, for example, a width (length) of 480 mm in the width direction W and a thickness of 50 to 200 μm. The fragrance-containing sheet 12 contains a polysaccharide polymer having a temperature-reversible gelling ability.

The thickening polysaccharide contained in the fragrance-containing sheet 12 has a property of fixing and covering the fragrance dispersed in the sheet. The thickening polysaccharide is, for example, a single component of carrageenan, agar, xanthan gum, gellan gum, psyllium seed gum, or konjak glucomannan; or carrageenan, locust bean gum, guar gum, agar, gellan gum, tamarind gum, xanthan gum, tara gum, konjak. It is a complex system combining two or more components selected from the group consisting of glucomannan, starch, cassia gum, and psyllium seed gum.

Preferably, the thickening polysaccharide is a single component system of carrageenan, agar, xanthan gum, or gellan gum; or carrageenan, agar, xanthan gum, or gellan gum, locust bean gum, guar gum, tamarind gum, tara gum, konjak glucomannan, cassia gum, etc. It is a complex system in which one or more components selected from the group consisting of psyllium seed gum and psyllium seed gum are combined.

More preferably, the thickening polysaccharide is selected from the group consisting of carrageenan, agar, xanthan gum, gellan gum, and a mixture of gellan gum and tamarind gum.

An aqueous solution of carrageenan, agar, xanthan gum or gellan gum gels when cooled below a certain temperature (ie, loses fluidity and solidifies), and once gelled, then raises the temperature to the temperature transferred to the gel. Even if it reaches, it does not easily sol and can maintain a gelled state (hereinafter referred to as "temperature-responsive sol-gel transition characteristic"). Therefore, when the raw material slurry contains any of carrageenan, agar, xanthan gum, and gellan gum as the thickening polysaccharide, the raw material slurry is once cooled and gelled, and the gelled raw material is dried at a high temperature to shorten the time. It has the advantage that the sheet can be manufactured in time.

More preferably, the thickening polysaccharide is selected from the group consisting of agar, gellan gum, and a mixture of gellan gum and tamarind gum.

When a mixture of gellan gum and tamarind gum is used as the thickening polysaccharide, the mass ratio of gellan gum to tamarind gum is preferably in the range of 1: 1 to 3: 1.

The blending amount of the thickening polysaccharide in the raw material slurry is preferably 10 to 35% by mass, more preferably 12 to 25% by mass, based on the total mass (that is, the amount of dry substance) of the components other than water in the raw material slurry. %. The blending amount (mass%) of the thickening polysaccharide can be calculated by using the value of the blending amount of each component other than water in the raw material slurry.

As the fragrance contained in the fragrance-containing sheet 12, any fragrance can be used as long as it is a fragrance used for smoking articles. The main flavors are menthol, leaf tobacco extract, natural vegetable flavors (eg cinnamon, sage, herbs, chamomile, kudzu, sweet tea, cloves, lavender, cardamon, chow, nutmeg, bergamot, geranium, honey essence, rose. Oil, Lemon, Orange, Kay Skin, Caraway, Jasmine, Ginger, Coriander, Vanilla Extract, Spare Mint, Peppermint, Cassia, Coffee, Cellory, Cascarilla, Sandalwood, Cocoa, Iran Iran, Fennel, Anis, Licoris, St. John's Bread , Sumomo extract, peach extract, etc.), sugars (eg, glucose, fructose, isomerized sugar, caramel, etc.), cocoa (powder, extract, etc.), esters (eg, isoamyl acetate, linalyl acetate, isoamyl propionate, butyric acid) Linalyl, etc.), ketones (eg, menthon, ionone, damasenone, ethylmaltor, etc.), alcohols (eg, geraniol, linalol, anatorol, eugenol, etc.), aldehydes (eg, vanillin, benzaldehyde, anisaldehyde, etc.), lactones. Classes (eg, γ-undecalactone, γ-nonalactone, etc.), animal fragrances (eg, musk, ambassalis, civet, castorium, etc.), hydrocarbons (eg, limonene, pinen, etc.). These fragrances may be used in solid form or may be dissolved or dispersed in a suitable solvent such as propylene glycol, ethyl alcohol, benzyl alcohol or triethyl citrate. Preferably, a fragrance in which a dispersed state is easily formed in the solvent by adding an emulsifier, for example, a hydrophobic fragrance or an oil-soluble fragrance can be used. These fragrances may be used alone or in combination.

The content of the fragrance in the sheet is preferably less than 18% by mass with respect to the total mass of the fragrance-containing sheet 12. The content of the fragrance in the sheet is more preferably 2.5% by mass or more and less than 18% by mass, still more preferably 2.5 to 12% by mass, and most preferably 3 to 6 with respect to the total mass of the fragrance-containing sheet. It is mass%.

The content of the emulsifier in the sheet is preferably 0.5 to 5% by mass, more preferably 1.0 to 4.5% by mass, based on the mass of the thickening polysaccharide in the sheet. The content of the emulsifier in the sheet can be calculated by using the value of the blending amount of the emulsifier and the thickening polysaccharide in the raw material slurry.

The bulking material contained in the perfume-containing sheet 12 plays a role of increasing the total mass (that is, the amount of dry matter) of the constituent components other than water in the raw material slurry, and finally increasing the bulk of the perfume-containing sheet. That is, the bulking material is a substance that only plays a role of increasing the bulk of the fragrance-containing sheet 12 and does not affect the original function of the fragrance-containing sheet 12. The bulking material is a substance that is permitted in the art to be added to smoking articles as an additive.

The bulking material is preferably a starch hydrolyzate. The starch hydrolyzate refers to a substance obtained by a process including a step of hydrolyzing starch. The starch hydrolyzate is, for example, a substance obtained by directly hydrolyzing starch (that is, dextrin) or a substance obtained by hydrolyzing starch after heat treatment (that is, indigestible dextrin).

The bulking material can exert the function of the bulking material by increasing the bulk of the sheet, and can be added in an amount that does not affect the flavor and taste of the smoking article. The content of the bulking material in the sheet is preferably 100 to 500% by mass, more preferably 200 to 500% by mass, based on the mass of the thickening polysaccharide. The content of the bulking agent in the sheet can be calculated by using the value of the blending amount of the bulking agent and the thickening polysaccharide in the raw material slurry.

By adding the bulking material to the raw material of the fragrance-containing sheet 12, even when the fragrance-containing sheet 12 has a composition in which the fragrance-containing concentration is low, the fragrance-containing sheet 12 can be produced under practical manufacturing conditions. It is possible to manufacture stably with. Specifically, since the bulking material plays a role of increasing the amount of dry substance in the raw material slurry and increasing the bulk of the sheet, it is possible to shorten the drying time required to produce a sheet having a desired thickness. can. Further, since the bulky material does not substantially increase the viscosity of the raw material slurry, it does not interfere with the kneading work and the stretching work of the raw material slurry.

Further, the fragrance-containing sheet 12 may contain water. That is, the water contained in the raw material slurry may remain on the fragrance-containing sheet 12 after drying. When water remains in the fragrance-containing sheet 12, the water content is preferably less than 10% by mass, more preferably 3 to 9% by mass, and further preferably 3 to 6% by mass with respect to the total mass of the sheet. ..

Subsequently, a method of manufacturing the fragrance-containing sheet 12 using the fragrance-containing sheet manufacturing apparatus 11 of the embodiment will be described with reference to FIGS. 4 to 9. As shown in FIG. 4, the method for producing a fragrance-containing sheet of the present embodiment includes four steps: a molding step, a gelling step, a slit forming step, and a drying step.

In the dam portion 15, the fragrance-containing slurry 14 as a raw material is held at 60 to 100 ° C. In the molding step, as shown in FIG. 5, the sol-like slurry 14 stored in the dam portion 15 is extruded together with the base material 16 from the first gap portion 17A and the second gap portion 17B of the molding mechanism 17 in the feeding direction A. As a result, the slurry 14 is formed into a sheet. At this time, the base material 16 is sent between the comma roll 32 and the coating roll 33, and the rotation of the coating roll 33 pushes out the slurry 14 together with the base material 16. At this time, the sheet-shaped molded fragrance-containing sheet 12 is in the form of a sol and has not yet been gelled. The fragrance-containing sheet 12 is placed on the base material 16.

In the gelling step, as shown in FIG. 6, the fragrance-containing sheet 12 sent in the feeding direction A is blown with cooling air (air) from above by the nozzle of the gelling mechanism 21 to make the fragrance-containing sheet 12 0. The fragrance-containing sheet 12 is gelled by cooling to a temperature of about 40 ° C.

In the slit forming step, as shown in FIG. 7, the fragrance-containing sheet 12 fed in the feeding direction A and gelled by the gelling mechanism 21 is covered by the slit forming portion 23 in whole or in part. A slit 22 having a corresponding depth is formed. The number of slits 22 formed is the same as the number of slit-forming components 38 provided in the slit-forming portion 23. Therefore, when the number of the slit forming parts 38 is 2, two slits 22 are also formed, and when the number of the slit forming parts 38 is three or more, three or more slits 22 are also formed. When the number of slit forming parts 38 is one, one slit is also formed.

The fragrance-containing sheet 12 is formed with a slit 22 so as to be separated by the slit-forming component 38 when passing through the slit-forming component 38 of the slit-forming portion 23. The depth of the slit 22 formed at this time is a depth corresponding to the entire thickness of the fragrance-containing sheet 12, and may be a depth for completely cutting the fragrance-containing sheet 12. Alternatively, the depth of the slit 22 is a depth corresponding to a part of the thickness of the fragrance-containing sheet 12, and is deep enough to make a notch on the fragrance-containing sheet 12, and the fragrance-containing sheet 12 is completely cut. It may be deep enough not to be used. In this case, it is preferable that the slit forming component 38 is fixedly provided with respect to the holding portion 41. It is preferable that the cutting depth of the slit 22 can be adjusted by adjusting the fixing position of the slit forming component 38 and manipulating the distance (gap) from the tip of the slit forming component 38 to the base material 16.

Prior to this slit forming step, since the perfume-containing sheet 12 has already been gelled, the slit shape is stored in the perfume-containing sheet 12 as shown in FIG. Therefore, the fragrance-containing sheet 12 once the slit 22 is formed does not rejoin and return to one fragrance-containing sheet 12.

When the number of the slit forming parts 38 is two, the slits 22 are provided in pairs in the vicinity of both ends of the fragrance-containing sheet 12 in the width direction W. More specifically, the slit 22 is provided at a position separating the fragrance-containing sheet 12 formed by the second gap 17B and the fragrance-containing sheet 12 formed by the first gap 17A. When the number of the slit forming parts 38 is one, it is provided in the vicinity of any end of the perfume-containing sheet 12 in the width direction W. Similarly, in this case, the slit 22 is provided at a position separating the fragrance-containing sheet 12 formed by the second gap 17B and the fragrance-containing sheet 12 formed by the first gap 17A.

When the number of the slit forming parts 38 is 3 or more, the two slits 22 are both ends of the fragrance-containing sheet 12 in the width direction W as in the case where the slit forming parts 38 are composed of two. It is provided in pairs in the vicinity of. Further, another slit 22 is provided at an arbitrary position (as an example, the central portion) in the width direction W of the fragrance-containing sheet 12.

In the drying step, as shown in FIGS. 1 and 9, in the process of sending the perfume-containing sheet 12 from the first drying chamber 24A to the fourth chamber 24D, warm air at 70 to 100 ° C. is blown from above and below to contain the perfume. The sheet 12 is dried. As a result, the water content in the fragrance-containing sheet 12 is evaporated, and the water content of the fragrance-containing sheet 12 is adjusted to an appropriate amount. Further, the fragrance-containing sheet 12 shrinks slightly as it dries, but the upper surface of the shrunk fragrance-containing sheet 12 is formed flat. As a result, the fragrance-containing sheet 12, which had the shape shown in FIG. 8 before drying, shrinks in the direction of the arrow to become the shape shown in FIG. As a result, the end portions having a large amount of water formed at both ends are separated from the main body of the fragrance-containing sheet 12. Even when the slit 22 is formed at a depth corresponding to a part of the thickness of the fragrance-containing sheet 12, stress concentration occurs around the slit 22 in the process of shrinking the fragrance-containing sheet 12 in the drying step, and the slit 22 is formed. It grows and, as a result, the end portion is separated from the main body of the perfume-containing sheet 12.

According to the first embodiment, the following can be said. The perfume-containing sheet manufacturing apparatus 11 has a feeding mechanism 18 for feeding the gelled perfume-containing sheet 12, and a depth corresponding to all or part of the thickness of the perfume-containing sheet 12 along the feeding direction A of the perfume-containing sheet 12. It is provided with a slit forming portion 23 for forming one or more slits 22 and a drying mechanism 24 for drying the fragrance-containing sheet 12 on which the slits 22 are formed.

In the method for producing a fragrance-containing sheet, the fragrance-containing slurry 14 is molded into a sheet by the molding mechanism 17, and the sheet-shaped slurry 14 sent in the feeding direction A is cooled by the gelling mechanism 21 to gelle the sheet. Is formed, and one or more slits 22 having a depth corresponding to all or part of the thickness of the gelled sheet are formed by the slit forming portion 23, and the gelled sheet including the one or more slits 22 is formed. Is dried by the drying mechanism 24.

As a result of diligent studies on the method for producing the fragrance-containing sheet, the inventors have found that when the fragrance-containing sheet 12 is dried by the drying mechanism 24, the thin portion of the fragrance-containing sheet 12 supports this in the initial stage of drying. It has been found that it adheres to the base portion (as an example, the base material 16) to form a fixing point. Further, the inventors have stated that when the sheet surface becomes a film and starts shrinking as the drying progresses, a strong tension is applied to the fixing point toward the central portion of the fragrance-containing sheet 12 in the width direction W. I also found that it would be. Further, the inventors have found that when the fragrance-containing sheet 12 is strongly adhered or adhered at the fixing point, the fragrance-containing sheet 12 is deformed due to shrinkage, the fixing point or its periphery is peeled off or broken, and the fragrance-containing sheet is damaged. It was found that the 12 itself may be cracked or broken. The fragrance-containing sheet 12 that is deformed, broken, or cracked in this way naturally becomes a defective product and cannot be used as a product.

According to the above configuration, since the slit 22 is formed in the gelled fragrance-containing sheet 12, the slit shape can be stored in the fragrance-containing sheet 12. Then, the fragrance-containing sheet 12 having the portion cut by the slit 22 can be manufactured via the drying mechanism 24. As a result, the fragrance-containing sheet 12 can be processed into a desired shape, and the tension (stress) generated in the fragrance-containing sheet 12 can be released by the slit 22. As a result, it is possible to prevent the fragrance-containing sheet 12 from being cracked or broken, and to manufacture the fragrance-containing sheet 12 having a constant quality. Even if the depth of the slit 22 is a depth corresponding to a part of the thickness of the fragrance-containing sheet 12, the slit 22 grows in the subsequent drying step (drying by a drying mechanism) and contains the fragrance in the slit 22. It does not matter because the sheet 12 is surely cut.

In the fragrance-containing sheet manufacturing apparatus 11, one or more slits 22 are one, the slit forming portion 23 has one slit forming component 38, and the one slit forming component 38 has one slit 22. It is provided at a position formed near one end of the width direction W of the fragrance-containing sheet 12.

In the method for producing a fragrance-containing sheet, one or more slits 22 are one, and the slit forming portion 23 forms the one slit 22 in the vicinity of one end of the width direction W of the gel-like sheet.

Under certain conditions, in the gelled fragrance-containing sheet 12, in the finished product after drying, the end portion may be thickened due to shrinkage, and a portion having a high water content may be formed at the end portion. In such a place where the amount of water is large, the gap between the gel crosslinks is large, and the fragrance contained in the sheet is easily volatilized together with the water. Further, under certain conditions, shrinkage during drying by the drying mechanism 24 may cause overdrying at the end portion of the perfume-containing sheet 12, which causes the end portion of the perfume-containing sheet 12 to curl and rise from the base material 16. Further, there is a possibility that the fragrance-containing sheet 12 may be peeled off from the base material 16 from the portion where the float is generated, or the fragrance-containing sheet 12 may be cracked or broken.

For this reason, in the fragrance-containing sheet 12, it is necessary to remove the end portion (one end portion) that tends to have a large amount of water content or, conversely, to be lifted, peeled off, or cracked due to overdrying, as an unnecessary portion. According to the above two configurations, the fragrance-containing sheet 12 can be divided into two by a simple configuration. This makes it possible to process the fragrance-containing sheet 12 into a desired state, such as removing unnecessary portions provided at the ends of the fragrance-containing sheet 12.

In the fragrance-containing sheet manufacturing apparatus 11, one or more slits 22 are two, the slit forming portion 23 has two slit forming parts 38, and one of the two slit forming parts 38 is two slits. One of the 22 is provided at a position formed near one end of the width direction W of the fragrance-containing sheet 12, and the other of the two slit-forming parts 38 has the other of the two slits 22 of the fragrance-containing sheet 12. It is provided at a position formed near the other end in the width direction W. Further, in the method for producing a fragrance-containing sheet, one or more slits 22 are two, and one of the two slits 22 is placed in the vicinity of one end of the fragrance-containing sheet 12 in the width direction by the slit forming portion 23. The other of the two slits 22 is formed in the vicinity of the other end of the fragrance-containing sheet 12 in the width direction W.

According to these configurations, the slits 22 can be separated from each other by forming slits 22 at both ends of the fragrance-containing sheet 12 which has a large amount of water or causes overdrying. Thereby, unnecessary portions can be removed from the fragrance-containing sheet 12, and the fragrance-containing sheet 12 can be easily processed into a desired state.

The fragrance-containing sheet manufacturing apparatus 11 includes a molding mechanism 17 for forming the fragrance-containing slurry 14 into a sheet to form the fragrance-containing sheet 12 before gelation. According to this configuration, the perfume-containing sheet 12 before gelation can be preliminarily molded into a predetermined shape by the molding mechanism 17.

In the fragrance-containing sheet manufacturing apparatus 11, the molding mechanism 17 is a first gap portion 17A, and the first gap portion 17A that defines the thickness of the fragrance-containing sheet 12 before gelation passing through the first gap portion 17A and the pre-gelling portion 17A. The second gap portion 17B provided at one end of the width direction W of the fragrance-containing sheet 12 and having a size smaller than that of the first gap portion 17A, and the fragrance-containing sheet 12 before gelation passing through the second gap portion 17B. It has a second gap portion 17B that defines the thickness. According to this configuration, by reducing the thickness of the perfume-containing sheet 12 passing through the second gap 17B in advance, the thickness of the portion formed by the second gap 17B due to shrinkage during drying performed by the drying mechanism 24 is increased. It is possible to prevent the formation of a large thickened portion. As a result, the amount of water does not become too large at the portion provided at the end portion, and the area that can be used as a product can be increased. Alternatively, depending on the condition setting, it is possible to omit the step itself of removing this portion as a defective portion.

The perfume-containing sheet manufacturing apparatus 11 is provided at a position between the molding mechanism 17 and the slit forming portion 23, and includes a gelling mechanism 21 for gelling the perfume-containing sheet 12 before gelling. According to this configuration, the time required for gelation can be shortened and the production line of the fragrance-containing sheet 12 can be shortened as compared with the case of utilizing gelation by natural heat dissipation.

The slit forming portion 23 has one or more slit forming parts 38 forming the one or more slits 22, and one of the one or more slit forming parts 38 contains a fragrance formed in the second gap portion 17B. It is provided at a position separated from the fragrance-containing sheet 12 formed by the sheet 12 and the first gap 17A by one slit 22. According to this configuration, if the slit 22 is formed at a position separating the fragrance-containing sheet 12 formed in the second gap 17B and the fragrance-containing sheet 12 formed in the first gap 17A, the slit 22 is thinned. 2 The portion formed by the gap portion 17B can be separated from the portion formed by the first gap portion 17A. As a result, the thickness of the fragrance-containing sheet 12 can be made substantially uniform, and the fragrance-containing sheet 12 having a constant thickness, the amount of fragrance remaining inside, the amount of water, and the like, that is, the quality can be obtained. As a result, the end portion (one end portion) that tends to be lifted, peeled off, or cracked due to overdrying can be removed as an unnecessary portion.

The fragrance-containing sheet manufacturing apparatus 11 has a sheet-shaped base material 16 on which the fragrance-containing sheet 12 is placed. According to this configuration, the pre-gelled fragrance-containing sheet 12 and the gelled fragrance-containing sheet 12 can be stably fed in the feeding direction A.

The slit forming portion 23 holds one slit forming component 38 forming one slit 22 and one or more slit forming components 38 so that the weight of the slit forming component 38 acts on the fragrance-containing sheet 12. 1 It has the above holding portion 41 and. According to this configuration, the fragrance-containing sheet 12 can be pushed off by the weight of the slit-forming component 38 by one or more slit-forming components 38. Thereby, the configuration of the slit forming portion 23 forming one or more slits 22 can be realized with a simple structure.

(Reference form)
Subsequently, with reference to FIGS. 10 to 12, the fragrance-containing sheet manufacturing apparatus 11 ′ according to the reference embodiment will be described. As shown in FIG. 10, in the molding mechanism 17, when the slurry 14 is molded to form the perfume-containing sheet 12 having a uniform thickness in the width direction W, the gelling step by the gelling mechanism 21 and the drying by the drying mechanism 24 are performed. Through the process, the dried fragrance-containing sheet 12 is produced. However, in the drying step, as shown by the arrow in FIG. 11, shrinkage occurs at both ends of the fragrance-containing sheet 12 in the width direction W, and under certain conditions, the portion where the film thickness is thickened at both ends as shown in FIG. 12A may be formed. In the thickened portion 12A, the water content is larger than that of the other portions, so that the gap between the gel crosslinks is large, and the fragrance contained in the sheet is easily volatilized together with the water content. ing. As a result of diligent studies on the method for producing the perfume-containing sheet 12 described in the above-described embodiment, the inventors have found that the perfume-containing sheet 12 having the thickened portion 12A may be a defective product and may be manufactured. It has been found that it is necessary to remove the thickened portion 12A in the process.

In the following modification, mainly the parts different from the above-described embodiment will be described, and the illustration and description of the parts common to them will be omitted.

(First modification)
The fragrance-containing sheet manufacturing apparatus 11 of the first modification will be described with reference to FIG. 13. In the first modification, the configuration of the molding mechanism 17 and the configuration of the slit forming portion 23 are different from those of the above embodiment.

The molding mechanism 17 has a comma roll 32 and a coating roll 33 facing the comma roll 32. As shown in FIGS. 2 and 13, the coating roll 33 is formed in a cylindrical shape. On the outer peripheral portion of the coating roll 33, a recess 35 recessed from the periphery is provided in a substantially intermediate portion in the axial direction.

In this modification, the coating roll 33 is composed of a stepped member (stepped roller) in order to partially reduce the coating thickness of the fragrance-containing sheet 12 as in the above embodiment. The stepped member has a recess 35 and a pair of large diameter portions 42 provided on the outside of the recess 35. The recess 35 is not provided with a pair of tapered portions 36. A small diameter portion 37 is provided in the recess 35. A pair of large diameter portions 42 are provided on the outside of the recess 35. The method of forming the large diameter portion 42 or the like is arbitrary. For example, the small diameter portion 37 and the large diameter portion 42 of the stepped member may be formed by machining (cutting, lathe processing) or the like, as in the above embodiment. In this modification, as an example of the forming method, each of the large diameter portions 42 is composed of, for example, a tape wound around the main body 33A (shaft portion) of the coating roll 33. The tape is adhered to the outer peripheral surface 34 of the main body 33A (shaft portion) of the coating roll 33.

The large diameter portion 42 is formed, for example, at a height of 10 to 100 μm from the outer peripheral surface 34, preferably 20 to 80 μm from the outer peripheral surface 34, and more preferably 40 to 60 μm from the outer peripheral surface 34. It is formed by the height. Therefore, in the present embodiment, the large diameter portion 42 is formed by winding and adhering a tape having such a thickness to the main body 33A of the coating roll 33.

The molding mechanism 17 further has a first gap portion 17A and a second gap portion 17B between the comma roll 32 and the coating roll 33. The first gap portion 17A corresponds to the small diameter portion 37. The second gap portion 17B corresponds to the large diameter portion 42. Therefore, the dimension H2 (height dimension) of the second gap portion 17B is smaller than the dimension H1 (height dimension) of the first gap portion 17A. The second gap 17B is provided in pairs on both sides of the first gap 17A, but may be provided only on one side adjacent to the first gap 17A.

The slit forming portion 23 has one or more slit forming parts 38 and a holding portion 41 for holding the slit forming parts 38. In the present embodiment, it is preferable that the slit forming parts 38 are provided in pairs so as to be located near both ends of the fragrance-containing sheet 12. The number of the slit forming parts 38 provided in the slit forming portion 23 is not limited to two, and may be three or more, or may be one.

In the present embodiment, the slit 22 having a depth corresponding to the entire thickness of the fragrance-containing sheet 12 is formed, but by changing the type of the slit-forming component 38, one of the thicknesses of the fragrance-containing sheet 12 is formed. It is also possible to form a slit 22 having a depth corresponding to the portion.

The slit forming portion 23 has a slit 22 at a position 1 to 10 mm, preferably 2 to 8 mm, and more preferably 3 to 6 mm from the end portion in the width direction W of the fragrance-containing sheet 12 by the slit forming component 38. To form a pair. The pair of slit-forming parts 38 are provided at positions where the slits 22 are formed in the fragrance-containing sheet 12 formed in the second gap portion 17B.

Subsequently, with reference to FIG. 13, a method for manufacturing a fragrance-containing sheet using the fragrance-containing sheet manufacturing apparatus 11 of the embodiment will be described. In the method for producing the fragrance-containing sheet 12 of this modification, only the slit forming step is different from the above embodiment, and this will be described below.

In the slit forming step, the slit forming portion 23 makes a slit 22 having a depth corresponding to all or part of the thickness of the fragrance-containing sheet 12 sent in the feeding direction A and gelled by the gelling mechanism 21. To form. The number of slits 22 formed is the same as the number of slit-forming components 38 provided in the slit-forming portion 23.

When the fragrance-containing sheet 12 passes through the slit-forming component 38 of the slit-forming portion 23, the slit 22 is formed so as to be pushed off by the slit-forming component 38 from above. Prior to this slit forming step, since the perfume-containing sheet 12 has already been gelled, the shape of the slit 22 is stored in the perfume-containing sheet 12.

When the number of the slit forming parts 38 is two, the slits 22 are provided in pairs in the vicinity of both ends of the fragrance-containing sheet 12 in the width direction W. More specifically, the slit 22 is provided at a position corresponding to the fragrance-containing sheet 12 formed in the second gap portion 17B. When the number of the slit forming parts 38 is one, it is provided in the vicinity of any end of the perfume-containing sheet 12 in the width direction W. In this case as well, the slit 22 is provided at a position corresponding to the fragrance-containing sheet 12 formed in the second gap portion 17B.

When the number of the slit forming parts 38 is 3 or more, the two slits 22 are both ends of the fragrance-containing sheet 12 in the width direction W as in the case where the slit forming parts 38 are composed of two. It is provided in pairs in the vicinity of. Further, another slit 22 is provided at an arbitrary position (for example, the central portion) in the width direction W of the fragrance-containing sheet 12.

According to this modification, the slit forming portion 23 has one or more slit forming parts 38, and one of the one or more slit forming parts 38 is a fragrance-containing sheet 12 formed in the second gap portion 17B. It is provided at a position where the slit 22 is formed. By forming the slit 22 in the fragrance-containing sheet 12 formed in the second gap 17B in this way, even if the position where the fragrance-containing sheet 12 is sent in the manufacturing process is slightly displaced in the width direction W, the slit 22 is formed. The slit 22 can be reliably formed at the planned position. Thereby, the generation rate of defective products can be reduced in consideration of the variation in the passing position of the fragrance-containing sheet 12 in the manufacturing process, and the yield of the fragrance-containing sheet 12 can be improved.

(Second modification)
The fragrance-containing sheet manufacturing apparatus 11 of the second modification will be described with reference to FIG. In the second modification, the width of the fragrance-containing sheet 12, the configuration of the molding mechanism 17, and the configuration of the slit forming portion 23 are different from those of the above embodiment. In this modification, a method of simultaneously producing a plurality of fragrance-containing sheets 12 having substantially the same width and the same composition will be described.

The molding mechanism 17 has a comma roll 32 and a coating roll 33 facing the comma roll 32. As shown in FIGS. 2 and 14, the coating roll 33 is formed in a cylindrical shape. In the present embodiment, the concave portion 35 is not provided on the outer peripheral portion of the coating roll 33.

The fragrance-containing sheet 12 has a width (length) of 1000 mm and a thickness of 350 to 1300 μm in the width direction W, for example, in the state before drying. The fragrance-containing sheet 12 has a width (length) of 960 mm and a thickness of 50 to 200 μm in the width direction W of the sheet in the dried state, for example. Therefore, the fragrance-containing sheet 12 of the second modification has the same thickness as the fragrance-containing sheet 12 of the above-described embodiment, and is formed to be longer, that is, wider in the width direction W than the above-mentioned embodiment. The fragrance-containing sheet 12 may be formed in a state before drying, for example, with a width (length) of 1000 mm or more in the width direction W.

The slit forming portion 23 has a plurality of (for example, two) slit forming parts 38 for forming the plurality of slits 22, and a plurality of holding portions 41 for holding the plurality of slit forming parts 38. The plurality of slit-forming parts 38 are provided apart from each other in the width direction W of the fragrance-containing sheet 12. In this modification, the perfume-containing sheet 12 includes a plurality of strips 12B separated by a plurality of slits 22. Then, the plurality of slit-forming parts 38 of the slit-forming portion 23 form a plurality of slits 22 so that the lengths of the plurality of strip-shaped portions 12B are substantially the same as each other in the width direction W of the fragrance-containing sheet 12. It is preferably provided at a position. In this modification, the slit forming portion 23 divides the perfume-containing sheet 12 into substantially equal intervals (three divisions) by the plurality of slits 22. At this time, the plurality of holding portions 41 (holders) of the slit forming portion 23 act on the base material 16 and the fragrance-containing sheet 12 from above so that the weight of the slit forming component 38 acts on the plurality of slit forming components 38. Holds.

When the fragrance-containing sheet 12 is 1000 mm or more in the width direction W, the number of slit-forming parts 38 provided in the slit-forming portion 23 may be three or more. Even when the number of the slit-forming parts 38 is 3, the three slit-forming parts 38 are provided at positions where the lengths of the plurality of strips 12B are substantially the same as each other. At this time, the slit forming portion 23 divides the fragrance-containing sheet 12 (divided into four) at substantially equal intervals by the plurality of slits 22. When the fragrance-containing sheet 12 is further widened in the width direction W, the number of the slit-forming parts 38 and the slits 22 may be further increased, and the number of the slit-forming parts 38 and the slits 22 may be four or more. That is, in this modification, the number of the slit forming parts 38 and the slits 22 is arbitrary, and can be appropriately increased or decreased according to the length of the fragrance-containing sheet 12 in the width direction W.

The operation of this modification will be described. In this modification, the fragrance-containing sheet 12 is formed wider than that of the above embodiment. Therefore, in the drying step by the drying mechanism 24, the amount of shrinkage due to drying is larger than that in the above embodiment. Therefore, when the slit 22 is not provided as in the present modification, for example, a fixing point is formed between the thin portion of the fragrance-containing sheet 12 and the base portion supporting the slit 22 during the drying step. To. Then, stress (tension) is generated between the fixing points due to shrinkage due to drying, and there is a possibility that cracks, breakage, etc. may occur at any place where such stress is concentrated. In this modification, unlike the above embodiment, the perfume-containing sheet 12 is divided by slits 22 at substantially equal intervals. Therefore, the fragrance-containing sheet 12 can be slid against the base material 16 at the place where the slit 22 is provided. Therefore, in this modification, the tension (stress) generated in the drying process is released at the position of each slit 22.

According to this modification, the following can be said. In the fragrance-containing sheet manufacturing apparatus 11, one or more slits 22 are a plurality, the fragrance-containing sheet 12 includes a plurality of strip-shaped portions 12B separated by the plurality of slits 22, and the slit forming portion 23 is a plurality of slits. It has a plurality of slit-forming parts 38 forming 22, and the plurality of slit-forming parts 38 have substantially the same length of each of the plurality of strips 12B with respect to the width direction W of the fragrance-containing sheet 12. As described above, it is provided at a position where a plurality of slits 22 are formed.

Further, in the method for producing a fragrance-containing sheet, one or more slits 22 are a plurality, the fragrance-containing sheet 12 includes a plurality of strip-shaped portions 12B separated by the plurality of slits 22, and the slit-forming portion 23 contains fragrance. A plurality of slits 22 are formed so that the lengths of the plurality of strips 12B in the width direction W of the sheet 12 are substantially the same as each other.

According to these configurations, for example, in the case where the fragrance-containing sheet 12 is formed wide, even if the tension (stress) generated by the shrinkage in the drying step becomes excessive, the tension is applied to the slit 22. It can be escaped at the position. Therefore, it is possible to prevent stress concentration from occurring at an unexpected location and cracking or breaking of the fragrance-containing sheet 12 in the vicinity of the stress concentration point. Thereby, the yield of the fragrance-containing sheet 12 can be improved.

The fragrance-containing sheet manufacturing apparatus 11 is not limited to those described in the above-described embodiment and each modification, and at the implementation stage, the components can be modified and embodied within a range that does not deviate from the gist thereof. Further, some components may be deleted from all the components shown in the embodiment and each modification, and the fragrance-containing sheet produced in any one of the embodiment, the first modification, and the second modification may be produced. As a matter of course, one invention can be configured by appropriately combining the devices 11 or the fragrance-containing sheet manufacturing methods.
