Description

  The present invention is a raw material storage container that enables stable operation by preventing a roll of a raw material from being unwound and deformed even when the paper material that is weakened by applying a chemical solution is wound. For example, it is applicable to storage and conveyance of the secondary raw material roll for tissue paper products used for a multi-stand type interfolder.

  A box of tissue paper is generally obtained by stacking multiple tissue papers by folding them with an interfolder (folding equipment) and cutting them into a predetermined length to obtain a tissue paper bundle. It is manufactured by storing in a storage box (tissue carton).

  As examples of such an interfolder, a multi-stand interfolder is known in addition to a rotary interfolder. As a conventional example of a manufacturing method using this multi-stand type interfolder, there is the following.

  First, a primary web roll (generally also called a jumbo roll) is manufactured by making sanitary thin paper in a papermaking facility and winding it, and then this primary web roll is set in a ply machine, and a plurality of primary rolls are produced. The primary continuous sheet unrolled from the raw fabric roll is overlapped and wound, and slitted (each product width of the tissue paper product in the width direction) to make it an even multiple of the product width of the tissue paper product, with a common paper tube. A secondary roll made of a plurality of plies is manufactured.

  Thereafter, secondary rolls manufactured by the ply machine are taken out of the ply machine and then set in a multi-stand type interfolder as many times as necessary. Next, the secondary continuous sheet is fed out from the secondary web roll and fed to the folding mechanism, where it is stacked while being folded, and then cut into a predetermined length to form a tissue paper bundle, which is stored in a storage box. . In addition, since the manufacturing method using such a multi-stand type interfolder has a large number (about 80 to 100 machines) of folding mechanism parts as compared with the manufacturing method using other folding equipment, it is produced. It has the advantage of high performance. Here, one unit of the folding mechanism unit is a unit of a mechanism that folds two rows of tissue paper slit into the product width of the tissue product so as to enter inside each other.

  By the way, currently, it is said that there is a demand of 800 tons / month for a moisturizing tissue paper, which is a tissue paper product in which a chemical solution such as a moisturizing agent is applied to the tissue paper product. As the population increases, the population and usage continue to increase, and demand is expanding. Therefore, as the demand for moisturizing tissue has increased, it has been necessary to manufacture the moisturizing tissue using a multi-stand type interfolder with higher productivity.

  In order to produce moisturizing tissue paper with a multi-stand type interfolder, various types of printing can be used in any of the paper making process, ply machine process (secondary roll roll production), and folding process (multi-stand type interfolder). It is necessary to apply and apply a chemical solution using a method such as a method, a spray method, a spray method, and an ink jet method. However, on-machine coating in the papermaking process is usually performed at a high speed of 1000 m / min or higher and low-viscosity chemicals, so there are technically difficult issues such as chemical splashes and low chemical yields. difficult.

In addition, in order to apply on-line chemical solution in a multi-stand type interfolder, a large number of chemical solution application devices are provided for each width corresponding to the supplied secondary roll width (sheet width that is an even multiple of the tissue product width). It is necessary to install it between the secondary roll roll feed-out part and the folding mechanism part, but at this time, it is difficult to manage the application amount of each chemical solution applicator uniformly, and a lot of equipment It is not practical because it costs money.
On the other hand, the chemical solution application in the ply machine process needs to be applied at a relatively high speed (usually 700 m / min or more), but basically it is possible to apply the chemical solution uniformly to a wide ply sheet. It is one of the effective chemical solution application methods because it is easy to circulate and recycle the chemical solution.

However, when the chemical solution is applied by the ply machine, the sanitary thin paper in a state where the chemical solution is applied is once wound up by the ply machine to become a secondary raw roll, but there are also some problems in this case.
In other words, this secondary web roll becomes a stock containing a chemical solution, but this secondary web roll is a large roll with a diameter of over 1 m, but this large roll secondary roll. In the original fabric roll, the sanitary thin paper is stretched by the hygiene thin paper being absorbed by the applied lotion chemical over time. In addition, the applied chemical solution lowers the frictional resistance of the sheet surface and makes it easier for the tissues to slip.

And the secondary original fabric roll which is the large roll original fabric with which the chemical | medical solution is apply | coated is processed by a multi-stand type | system | group interfolder after letting moisture absorb for a predetermined time, and becomes tissue paper. However, there is a possibility that the secondary web roll rolls out when it is processed into tissue paper as the secondary web roll absorbs the chemical.
In other words, before being processed by the multi-stand type inter-folder, the moisture in the air in the storage location is kept particularly in the original fabric while being held for a predetermined time in the state of the secondary raw roll. It absorbs from the outer peripheral side. Therefore, with time, the secondary raw roll absorbs moisture, the crepe of the sheet extends, and the sheet extends in the flow direction. When the sheet extends in the flow direction, the secondary raw roll is loosened and weakened by pressure from the thickness direction in the roll state, and the roll is easily deformed. In addition to this, the fact that the sheet surfaces are slidable with each other by applying the chemical solution to the secondary raw roll also facilitates the ease of deformation of the roll.

On the other hand, it is necessary to move a large roll of secondary web roll between processes. At the time of this movement, conventionally, the secondary web roll coated with a chemical solution is held by a clamp and moved. As a result, the clamping pressure causes the sandwiched portion of the secondary roll R to be deformed as shown in FIG. 18 so that the sandwiched pressure is distributed between the sheets. It is considered that the winding sheet misalignment occurs in the same manner as described above, and the secondary sheet roll is deformed in the same manner as described above. It was.
In addition, with the occurrence of this winding deviation, there is a defect that a defective product in which wrinkles enter a tissue paper as a finished product occurs.

On the other hand, various structures are known in order to prevent unwinding of the original fabric.
For example, as shown in Patent Document 1, a roll body conveying device that has a core at the center and delivers two roll bodies, and receives a roll body as shown in Patent Document 2, and prevents damage due to misalignment of the original fabric during operation. 2. Description of the Related Art A roll body transport device and a roll body transport device that receives a roll body as shown in Patent Document 3 and prevents a collision due to a winding deviation of an original fabric during an operation are known.

JP 2008-214069 JP 2008-195525 A JP 2008-214004 A

  However, even with the structures shown in these patent documents, there is no such thing as preventing sagging and deformation with respect to sanitary thin paper, which is a paper material such as tissue paper, and it is an original fabric over time. As a result of hygroscopic absorption of the sanitary thin paper constituting the secondary web roll, there was nothing that could prevent winding slippage and deformation that occurred during storage and transport of the secondary web roll.

  Therefore, the main problem of the present invention is that even a raw material wound with a weakened paper material coated with a chemical solution can be prevented from being unwound or deformed and can be stably operated. The purpose is to provide a stock storage.

The storage for original fabric according to claim 1 is a storage main body capable of storing an original fabric wound with paper,
A guide member for guiding when the raw material is inserted into the storage body,
A lid member capable of opening and closing the storage body and capable of sealing the space in the storage body when closed;
including.

The operation of the stock storage box according to claim 1 will be described below.
According to the storage container for raw material of this claim, the guide member guides the raw material when the original material wound with the paper material is inserted into the storage main body that can store the raw material. Moreover, it has the cover member which can open and close a storage main body, and when this cover member is closed, the space in a storage main body can be sealed.

  Therefore, for example, after a material that has been wound up after slitting is inserted into the stocker body of the stocker for the stock, the open part for inserting the stock of the stocker is closed with a lid member. As a result, the space in the storage body is sealed. When the raw material is stored in the stocker body of the raw material storage in this way, the internal space is narrow, so that it becomes difficult for the raw material to absorb moisture from the outside air, so that it is difficult for winding slippage to occur. In addition, deformation of the original fabric can be prevented.

  In addition, after being inserted into the stock storage, the stock is moved together with the stock storage, and the lid member is opened to, for example, a multi-stand type inter-folder for post-processing. The original material taken out from is attached. In this way, by adopting a stock storage that enables the stock to be stored and moving the stock together with the stock storage, there is no need to grip the stock with a clamp, and a multi-stand type interfolder It is now possible to easily set the original fabric.

  As described above, according to the stock storage for a raw material according to the present claim, since it is not necessary to hold the raw material with a clamp, not only deformation and scratches on the raw material are minimized, but also a sealed state. For this reason, even when the moisture absorption is further suppressed and the raw material is stored for a long period of time, the amount of moisture absorption does not increase, so that it is difficult to cause a winding slip. As a result, even when the original fabric is temporarily stored in a warehouse or the like, it is easy to carry out post-processing and improve the processing quality in accordance with the fact that the winding deviation and deformation of the original fabric can be reliably prevented.

  As a result of the above, it is possible to perform post-processing without any problem even if the raw material is coated with a chemical solution, and the original material can be easily set in, for example, a multi-stand type interfolder. Stable operation becomes possible. Accordingly, the product coated with the chemical solution can be produced without waste, and the production quantity is improved, so that the manufacturing cost can be reduced.

The operation of the stock storage box according to claim 2 will be described below.
The stock storehouse according to the present invention has the same effect as that of the first invention. However, in this claim, the storage body is formed in a cylindrical shape with one end open, and the lid member is formed in a disk shape and attached to one end of the storage body, and the other end of the storage body and The lid member is provided with elastic support members for supporting the original fabric, and the guide member is configured as a free belt that rotates with the insertion of the original fabric. The term “free belt” as used herein includes a group of rollers that are installed so as to be substantially continuous on a plane at intervals, and an endless belt having a cushioning property that circulates so as to surround them.

In other words, according to this claim, the storage body is formed in a cylindrical shape in accordance with the shape of the original fabric, and the lid member is formed in a disk shape, so that the space in the original storage case is minimized. As a result, the amount of moisture absorption is further suppressed.
Moreover, according to this claim, not only the elastic support member for supporting the original fabric is installed on the other end of the storage body and the lid member, but also the guide member for guiding the original fabric is a free belt. Yes. Thus, even when the stock storage is transported to move the stock, the elastic support member protects the free belt and the free belt serves as a cushion. Less.

The operation of the stock storage box according to claim 3 will be described below.
The stock storehouse according to the present invention has the same effects as the inventions of the first and second aspects. However, in this claim, the guide member is composed of at least two free belts arranged side by side in the lower part of the storage body, and the gap between the widthwise center of the free belt located on the outermost side and the center of the original fabric. It has the structure that the angle with respect to the perpendicular extending from the center of the original fabric of connecting line segments is 20 degrees or more.

  That is, according to this claim, not only the at least two free belts each play a role of a cushion, but also the free belt positioned at the outermost side is inclined at an appropriate angle, so that it goes toward the center of the storage body. Force is always generated against the original fabric by these free belts. Along with this, even when the original fabric storage is transported, the original fabric is not easily deformed without impacting the original fabric not only in the axial direction but also in the radial direction.

The operation of the stock storage box according to claim 4 will be described below.
The stock storehouse according to the present invention has the same effects as the inventions of the first to third aspects. However, the present invention has a configuration in which a support base is provided in a portion of the storage body that is the lower part of the guide member, and a pair of holes are formed side by side on the support base.

That is, according to this claim, since the pair of holes are formed side by side on the support base that exists in the portion of the storage body that is the lower part of the guide member, a pair of forklifts is formed in the pair of holes. By inserting each of the forks, the pair of forks can be reliably supported by the portion directly below the center of gravity of the original fabric, and the original storage can be easily transported.
As for the method of putting the secondary web roll into the stock storage, the method of pushing the secondary web roll with the conveyor in the axial direction or the method of pushing with the pusher from the rear of the slit surface of the secondary web roll. It is done. Conversely, with regard to the method of pulling out the secondary web roll from the stock storage, the drawer bar with chucking is inserted into the paper tube of the secondary roll and pulled out by the conveyor while being pulled out in the axial direction. be able to. In any case, when force is applied to the secondary roll, design considerations are taken so as not to cause deformation of the roll.

  As described above, according to the original fabric storage container of the present invention, even when the paper material that has been weakened by the application of a chemical solution is wound up, the original fabric is prevented from being unwound or deformed and stable. An excellent effect is made that the operation can be performed.

Next, an embodiment of the present invention will be described. In the figure, the arrow HD indicates the horizontal direction, and the arrow LD indicates the vertical direction.
[Method for producing primary roll]
An example of the manufacturing method of a primary fabric roll is demonstrated referring FIG.
As shown in FIG. 1, the wet paper W that has passed through the wire part is placed on the bottom felt 111 and transferred, and thereafter, sandwiched between the top felt 110 and the bottom felt 111, between the top roll 112 and the bottom roll 113. Passed and squeezed. Thereafter, the wet paper web W squeezed is attached to the surface of the Yankee dryer 115 via the touch roll 116 while being placed on the top felt 110. Then, the wet paper W is dried by the Yankee dryer 115, peeled off by the doctor blade 117, and then wound up to be a primary raw roll JR.
When making this paper, for example, adding a suitable agent such as a dispersant, a dry paper strength enhancer, a wet paper strength enhancer, a softener, a release agent, a coating agent, a pH adjuster such as caustic soda, an antifoaming agent, and a dye. can do.
In the method of manufacturing the primary raw roll, the smoothing process can be performed by the calendar means 118 after being peeled off by the doctor blade 117.

[Production facilities for secondary rolls for tissue paper products]
As shown in FIG. 11, the production facility X1 (ply machine X1) for the secondary paper roll for tissue paper products according to the present invention includes at least two primary web rolls JR manufactured by the above-described manufacturing method or the like. The ply means 51 is configured so that the primary continuous sheet S1 fed from the primary raw roll JR can be laminated along the continuous direction to form a laminated continuous sheet S2.

  A pair of chemical solution applying means 53 for applying a chemical solution to the laminated continuous sheet S <b> 2 flowing from the ply means 51 is provided at the subsequent stage of the ply means 51. Slit means 55 is arranged, which is composed of a plurality of cutters, and slits the laminated continuous sheet S2 transferred from the chemical solution applying means 53 so as to have a product width of tissue paper products or a multiple of the width. Then, at the subsequent stage of the slit means 55, the laminated continuous sheet S2 slit by the slit means 55 is coaxially wound to form a plurality of secondary raw rolls R having a product width of tissue paper products or a multiple of the width. Winding means 56 is provided. Here, the winding means 56 has two winding drums 56A for guiding each slit continuous sheet S2 to the secondary raw roll R, and these two winding drums 56A are secondary. The laminated continuous sheet S2 is guided in contact with the outer peripheral surface of the raw roll R.

(Calendar means)
One or more calendering means 52 for calendering the laminated continuous sheet S2 may be provided in the production facility X1 for the secondary paper roll for tissue paper products.
The type of calendar in the calendar means 52 is not particularly limited, but is preferably a soft calendar or a chilled calendar for the purpose of improving the smoothness of the surface and adjusting the paper thickness. A soft calendar is a calendar using a roll coated with an elastic material such as urethane rubber, and a chilled calendar is a calendar made of a metal roll.
The number of calendar means 52 can be changed as appropriate. If there is a plurality of installations, it has the advantage that it can be sufficiently smoothed even if the processing speed is high.
When two or more calendar means 52 are installed, they can be arranged side by side in the horizontal direction, the up-down direction, or the diagonal direction, and these installation directions may be combined. When arranged side by side in the horizontal direction, the holding angle becomes smaller, so the processing speed can be increased, and when arranged side by side in the vertical direction, the installation space can be reduced. Note that the holding angle referred to here means an angle during which the sheet is in contact with the center of the roll axis (a part of a circular arc of a cross section perpendicular to the axis).
Paper making is also performed as control factors such as calendar type, nip line pressure, and number of nips in the calendar processing conditions, and these control factors are preferably changed as appropriate according to the required sheet quality, that is, the sheet thickness and surface properties.
Further, the installation position of the calendar means 52 is not particularly limited. However, the calendar means 52 is positioned after the ply means 51 and before the chemical solution applying means 53, or after the chemical solution applying means 53 and before the contact embossing means 54. Can do.

(Medicating means)
The chemical solution applying step for applying a chemical solution to the laminated continuous sheet S2 is performed by the chemical solution applying unit 53. Specifically, the chemical solution applying unit 53 includes two chemical solution applying units 53A and 53B in a doctor chamber format, respectively. The chemical solution is applied by these two chemical solution application portions 53A and 53B. And while conveying laminated | multilayer continuous sheet S2 at a speed | rate of 700 m / min or more, Preferably it is 900 m / min or more, the lotion agent used as a chemical | medical solution is 1.5g-5g in total of both surfaces by these chemical | medical solution provision means 53A, 53B. The coating amount is / m ² .
The coating amount was calculated from the difference between each sheet basis weight when the chemical solution after ply was not applied during operation and each sheet basis weight immediately after the corresponding application.
(Coating amount g / m ²⁾ = (basis weight g / m ² immediately after coating) - (the basis weight g / m ² in the case of not applying)
The coating amount of both surface layers or the total coating amount of both surfaces is the total coating amount per unit area of the plyed tissue paper sheet, and the coating amount of each sheet is added.

  That is, as shown in FIG. 11 and FIG. 12, the chemical solution application unit 53A in the form of one of the doctor chambers is arranged such that the doctor chamber 61A containing the chemical solution is opposed to the rotatable anilox roll 63A, The chemical solution is delivered from the doctor chamber 61A to the anilox roll 63A. Further, a printing plate roll 64A that is in contact with the anilox roll 63A and is also in contact with one surface of the laminated continuous sheet S2 is rotatably installed, and a chemical solution is delivered from the anilox roll 63A to the printing plate roll 64A. Further, while applying pressure to the laminated continuous sheet S2 with the impression cylinder 65A facing the printing plate roll 64A across the laminated continuous sheet S2, the chemical solution is applied from the printing plate roll 64A to the laminated continuous sheet S2. It has become.

  In the present embodiment, the chemical solution application portion 53A is positioned on the surface side of the laminated continuous sheet S2 that faces a roller 54A of a contact embossing means 54 described later and also faces the winding drum 56A. A supply pump (not shown) for applying a chemical solution to the doctor chamber 61A and a discharge supply pump (not shown) for returning the chemical solution from the doctor chamber 61A are installed in the doctor chamber 61A.

  On the other hand, as shown in FIG.11 and FIG.12, the chemical | medical solution provision part 53B made into the other doctor chamber form is arrange | positioned facing the rotatable anilox roll 63B in the doctor chamber 61B containing the chemical | medical solution, The chemical solution is delivered from the doctor chamber 61B to the anilox roll 63B. Further, a printing plate roll 64B that is in contact with the anilox roll 63B and is also in contact with the other surface of the laminated continuous sheet S2 is rotatably installed, and a chemical solution is delivered from the anilox roll 63B to the printing plate roll 64B. Yes. Further, while applying pressure to the laminated continuous sheet S2 with the impression cylinder 65B facing the printing plate roll 64B across the laminated continuous sheet S2, the chemical solution is applied from the printing plate roll 64B to the laminated continuous sheet S2. It has become.

  And in this Embodiment, this chemical | medical solution provision part 53B is located in the other surface side of the lamination | stacking continuous sheet S2 which is made not to oppose the roller 54A, and is also not made to oppose the above-mentioned winding drum 56A. A supply pump (not shown) for applying a chemical to the doctor chamber 61B and a discharge supply pump (not shown) for returning the chemical from the doctor chamber 61B are also installed in the doctor chamber 61B. .

  Accordingly, the chemical solution is applied to both surfaces of the laminated continuous sheet S2 from the chemical solution applying unit 53A and the chemical solution applying unit 53B. At this time, the coating amount on the surface side of the laminated continuous sheet S2 facing the roller 54A by the chemical solution applying unit 53A Is applied to the laminated continuous sheet S2 from both sides of the laminated continuous sheet S2, while reducing the amount of the liquid applied to the other surface side by the chemical liquid applying unit 53B.

However, the total coating amount on both sides is 1.5 to 5 g / m ² as described above, and the coating amount on the outer peripheral surface of the secondary web roll R which is a ply web roll is the secondary web roll R. The coating amount is less than the inner peripheral surface. Of the total application amount of the lotion agent on both sides of the paper, the application amount on the outer peripheral surface of the secondary raw roll R is preferably 20% or more and less than 50%, but the specific value is 2 Since the optimum conditions differ depending on the balance between the slip and quality of the next raw roll R, the thickness of the sheet, the permeability of the lotion agent, and the transferability, it varies within the above range.
Specifically, it is possible not only to change the coating amount on each side, but also to roughen the flexographic plate so that the number of lines of the flexographic plate is about 15 to 40 lines and the apex area ratio is about 20 to 40% so that the chemical solution does not scatter. By doing so, a dot pattern remains immediately after application, and an application part and an unapplication part can be instantaneously formed.

Therefore, according to the present embodiment, since the plate is made of resin using the flexo type and is elastic, it can be adjusted by the printing pressure even if there is some unevenness on the sanitary thin paper. Wrinkles are less likely to enter the laminated continuous sheet S2 than when applied by a roll. On the other hand, by using a flexo format that applies flexographic printing, the coating amount can be stabilized even at high processing speeds, and a wide range of chemical viscosity can be stably applied with one roll. It becomes like this. Specifically, the lotion agent used as a chemical solution is applied at an application amount of 1.5 g to 5 g / m ² while the laminated continuous sheet S2 is set to 700 m / min or more, preferably at a speed of 900 m / min or more. Even in such a case, the laminated continuous sheet S2 can be wound up without being meandered and applied uniformly.

In addition, the base paper used in this embodiment is 1 ply, has a basis weight of 10 to 25 g / m ² , and a crepe rate of 10 to 30%. It is a sanitary thin paper having a paper strength of 100 to 300 cN / 25 mm and a wet paper strength of 50 to 150 cN / 25 mm.

  One or a plurality of the chemical solution applying means 53 of the present embodiment can be installed. When a plurality of chemical solution applying means 53 are installed, they may be arranged in the horizontal direction, the vertical direction, or the oblique direction, and these installation directions including the horizontal direction. May be arranged in combination. Since the holding angle is reduced when they are arranged in parallel in the horizontal direction, the processing speed can be increased, and when they are arranged in the vertical direction, the installation space can be reduced.

  The means (calendar means 52 and contact embossing means 54 in the example of FIG. 11) arranged before and after the chemical solution applying means 53 are preferably arranged close to each other. By doing so, when manufacturing a tissue paper product to which no chemical solution is applied, the laminated continuous sheet S2 is directly transferred from the front stage to the rear stage of the chemical solution applying unit 53, and the laminated continuous sheet S2 is not passed through the chemical solution applying unit 53. Since it only needs to flow, it is possible to easily switch the presence or absence of chemical application. For example, in the manufacturing equipment X1 for the secondary paper roll for tissue paper products shown in FIG. 11, when manufacturing the tissue paper products to which no chemical solution is applied, as shown by the two-dot chain line in FIG. It is only necessary to transfer directly from the means 52 to the contact embossing means 54 and to flow the laminated continuous sheet S2 without passing through the chemical solution applying means 53.

In addition, the following requirements are conceivable as the requirements of the accompanying chemical solution applying means 53.
In the two-roll flexo chemical solution application means, it is necessary to install a filter device for paper powder and air contained in the chemical solution circulating in the coating device such as a chemical solution tank. In the case of using the chemical solution applying means 53, it is not necessary to remove paper dust or the like, so that the load on the filtration device may be reduced. Furthermore, it may be necessary to control the temperature of the chemical solution within the coating apparatus such as the doctor chambers 61A and 61B to stabilize the viscosity of the chemical solution. However, a heater can be installed in the intermediate tank and piping connected to the doctor chambers 61A and 61B. . On the other hand, it is considered necessary to control the coating amount by the moisture content in the width direction of the laminated continuous sheet S2 during operation. For example, the moisture amount and variation in the width direction can always be checked using an infrared inspection machine or the like. .

(Medical solution)
About the chemical | medical solution to apply | coat, the viscosity of 1-700 mPa * s is desirable at 40 degreeC from a viewpoint of performing high-speed processing. If it is less than 1 mPa · s, the chemical solution is likely to be scattered on rolls such as anilox roll, printing plate roll, and gravure roll, and conversely if it is more than 700 mPa · s, it is difficult to control the amount applied to each roll or thin paper. Ingredients contain 70-90% polyol, 1-15% moisture, and 0.01-22% functional drug.

The polyol includes polyhydric alcohols such as glycerin, diglycerin, propylene glycol, 1,3-butylene glycol, polyethylene glycol, and derivatives thereof, and saccharides such as sorbitol, glucose, xylitol, maltose, maltitol, mannitol, and trehalose.
Functional agents include softeners, surfactants, inorganic and organic fine particle powders, oily components, and the like. Softeners and surfactants have the effect of imparting flexibility to the tissue and smoothing the surface, and anionic surfactants, cationic surfactants and zwitterionic surfactants are applied. Inorganic and organic fine particle powders have a smooth surface. The oil component has a function of improving lubricity, and higher alcohols such as liquid paraffin, cetanol, stearyl alcohol, and oleyl alcohol can be used.
In addition, as a functional agent, one of a hydrophilic polymer gelling agent, collagen, hydrolyzed collagen, hydrolyzed keratin, hydrolyzed silk, hyaluronic acid or a salt thereof, ceramide, etc. A moisturizing agent such as any combination can be added.
Deodorants such as flavors, emollients such as various natural extracts, vitamins, emulsifiers that stabilize compounding ingredients, antifoaming agents, antifungal agents, organic acids, etc. An agent can be appropriately blended. Furthermore, you may contain the antioxidant of vitamin C and vitamin E.
Of the above components, it is preferable to use a polyhydric alcohol such as glycerin or propylene glycol as a main component in order to stabilize the viscosity and coating amount of the chemical solution.
The temperature at the time of chemical solution application is preferably 30 ° C to 60 ° C, preferably 35 ° C to 55 ° C.

(Contact embossing means)
The production facility X1 for the secondary paper roll for tissue paper products can be provided with contact embossing means 54 for imparting contact embossing to the laminated continuous sheet S2. And the joining process for forming the contact embossing CE which is a line-shaped junction part which prevents delamination with respect to lamination | stacking continuous sheet S2 is performed by this contact embossing means 54. FIG.

Here, as shown in FIG. 13, the contact embossing means 54 includes a pressure drum 54B, which is a receiving roll, and a metal, hard roller 54A having fine convex portions 54C on the surface, with a predetermined pressure. The outer peripheral surfaces are in contact with each other while being rotatably installed. Then, with respect to the portion corresponding to the center in the width direction of the tissue paper product in the laminated continuous sheet S2, the laminated continuous sheet S2 is conveyed while sandwiching the laminated continuous sheet S2 between the convex portion 54C and the impression cylinder 54B that exist on each of the left and right. Thus, line-shaped contact embossing CE for preventing delamination along the continuous direction of the laminated continuous sheet S2 is applied to the laminated continuous sheet S2.
In addition, the winding means 56 mentioned above winds up the lamination | stacking continuous sheet S2 by making the surface on the side facing the roller 54A which performs this contact embossing CE into an outer peripheral side.

Thus, by providing the contact embossing CE, delamination of the laminated continuous sheet S2 formed by laminating a plurality of primary continuous sheets S1 is prevented. In addition, it is preferable that the contact embossing CE is formed so as to be positioned on both sides in the width direction of the tissue paper product so that the end portion of the tissue paper product is hardly delaminated.
The location where the contact embossing means 54 is installed is not particularly limited, but it is a stage subsequent to the chemical solution applying means 53 and preceding the slit means 55, and a stage subsequent to the calendar means 52 and preceding the chemical solution applying means 53. Can be considered. That is, it suffices if it is located at a position after the calendar means 52 and before the slit means 55.

Further, in this joining process, in the present embodiment, a metal and hard roller 54A having a fine convex portion 54C on the surface is used as a roller, but a line-shaped joint that prevents delamination from the laminated continuous sheet S2. For example, instead of the roller 54A, a roller having a fine needle-like member on the surface can be used as the roller.
Furthermore, the means for joining is not limited to the above example, and the tip shape of the convex portion may be a point, square, rectangular, circular, elliptical shape, etc. A tip having a slender linear shape or a thin and slanting linear shape may be used as the roller.
On the other hand, the arrangement of the protrusions may be equally spaced, but may not be staggered or evenly spaced. In addition to arranging the protrusions in a row and providing contact embossing continuously, It is also conceivable to arrange the parts in two or more rows. Then, a plurality of groups in which convex portions are arranged so as to provide a plurality of rows of contact embossing closely may be arranged to provide a plurality of contact embossing groups. In addition, as a joining process, you may join by other means, such as an ultrasonic wave, besides joining by applying a pressure mechanically as mentioned above.

(Primary continuous sheet)
The raw material pulp of primary continuous sheet S1 is not specifically limited, A suitable raw material pulp can be selected and used according to the use of tissue paper products. As raw material pulp, for example, wood pulp, non-wood pulp, synthetic pulp, waste paper pulp, and the like, more specifically, groundwood pulp (GP), stone ground pulp (SGP), refiner ground pulp (RGP), pressure type Mechanical pulp (MP), chemical mechanical pulp (CGP), semi-chemical pulp (such as ground pulp (PGW), thermomechanical pulp (TMP), chemithermomechanical pulp (CTMP), bleach chemithermomechanical pulp (BCTMP) Chemical pulp (SCP), kraft pulp (KP) such as hardwood bleached kraft pulp (LBKP), softwood bleached kraft pulp (NBKP), soda pulp (AP), sulfite pulp (SP), dissolved pulp (DP), etc. CP), nylon, rayon, polyester, polyvinyl alcohol Synthetic pulp made from (PVA) etc., deinked pulp (DIP), waste paper pulp such as waist pulp (WP), waste pulp (TP), cotton, flax, hemp, jute, manila hemp, ramie etc. One or several kinds of rag pulp, straw pulp, esparto pulp, bagasse pulp, bamboo pulp, kenaf pulp, and other auxiliary pulps such as bast pulp can be appropriately selected and used.

  In particular, the raw material pulp is preferably a blend of NBKP and LBKP. Waste paper pulp may be blended as appropriate, but it may be composed only of NBKP and LBKP in terms of texture and the like, and the blending ratio (JIS P 8120) in that case is NBKP: LBKP = 2: 8-8: 2 is good, and NBKP: LBKP = 4: 6-7: 3 is particularly desirable.

The primary continuous sheet S1 has a basis weight according to JIS P 8124 of 10 to 25 g / m ² , preferably 12 to 20 g / m ^2, and more preferably 13 to 16 g / m ² . When the basis weight is less than 10 g / m ² , it is preferable in terms of softness, but an appropriate strength cannot be ensured. On the other hand, when the basis weight exceeds 25 g / m ² , it becomes too hard and the touch is deteriorated.
Further, the paper thickness (measured with a Peacock manufactured by Ozaki Seisakusho) is 80 to 250 μm, preferably 100 to 200 μm, more preferably 130 to 180 μm with 2 plies.

  The primary continuous sheet S1 preferably has a crepe rate of 10 to 30%, more preferably 12 to 25%, and particularly preferably 13 to 20%. When the crepe rate is less than 10%, it becomes a tissue paper product that is easy to break during processing and has little stretch and is not stiff. When the crepe rate is 30% or more, it becomes difficult to control the tension of the sheet during processing, and it becomes a tissue paper product in which wrinkles are generated or the touch is poor.

  The primary continuous sheet S1 has a dry tensile strength (hereinafter also referred to as dry paper strength) specified in JIS P 8113 of 2 to 200 p-200 cN / 25 mm, preferably 250 to 600 cN / 25 mm, particularly preferably. The lateral direction is 100 to 300 cN / 25 mm, preferably 130 to 270 cN / 25 mm, particularly preferably 150 to 250 cN / 25 mm with 2 plies. If the dry tension of the base paper is too low, troubles such as tearing and elongation are likely to occur during production, and if it is too high, the touch becomes stiff when used.

  These paper strengths can be adjusted by a known method. For example, a paper strength agent is internally added (added to a stage before the dryer part, for example, pulp slurry), and pulp freeness is reduced (for example, about 30 to 40 ml is reduced). The method of increasing the NBKP compounding ratio (for example, 50% or more) can be appropriately combined.

  As the dry paper strength agent, starch, polyacrylamide, CMC (carboxymethyl cellulose) or a salt thereof such as sodium carboxymethyl cellulose, carboxymethyl cellulose calcium, carboxymethyl cellulose zinc and the like can be used. As the wet paper strength agent, polyamide polyamine epichlorohydrin resin, urea resin, acid colloid / melamine resin, thermal crosslinkability imparting PAM and the like can be used. When the wet paper strength agent is internally added, the addition amount can be about 5 to 20 kg / t in weight ratio to the pulp slurry. In addition, when the dry paper strength agent is internally added, the addition amount can be about 0.5 to 1.0 kg / t by weight ratio to the pulp slurry.

[Method for producing secondary roll for tissue paper product]
Next, an example of the manufacturing method of the secondary raw material roll for tissue paper products concerning this invention is demonstrated. The manufacturing method of the secondary raw material roll for tissue paper products which concerns on this form can be performed using the manufacturing equipment X1 of the secondary raw material roll for tissue paper products mentioned above, for example.
As shown in FIG. 11, in the manufacturing method of the secondary raw material roll for tissue paper products which concerns on this invention, the primary continuous sheet S1 paid out from the several primary raw material roll by the ply means 51 is followed along the continuous direction. The laminated continuous sheet S2 is laminated (laminating step), a chemical solution is applied to the laminated continuous sheet S2 by a pair of chemical solution applying means 53 (chemical solution applying step), and the laminated continuous sheet S2 is tissue paper product by the slit means 55. The product width of the paper product or a multiple of the product width is then slit (slit process), and then the laminated continuous sheet S2 slit in the slit process is coaxially wound to obtain the product width of the tissue paper product or a multiple of the product width A plurality of secondary web rolls R are formed by the winding means 56.

  In addition, in the manufacturing method of the secondary raw material roll for tissue paper products which concerns on this form, it is a back | latter stage of a lamination process and a chemical | medical solution application | coating process similarly to the manufacturing equipment X1 of the secondary raw material roll for tissue paper products mentioned above. A smoothing step of smoothing the laminated continuous sheet S2 with a pair of calendar means 52 can be provided in the preceding stage. In addition, a contact embossing step for performing line-shaped contact embossing for preventing delamination by the contact embossing means 54 on the laminated continuous sheet S2 can be provided after the chemical solution applying step and before the slitting step.

  In the manufacturing equipment or manufacturing method of the secondary paper roll for tissue paper products according to the present embodiment, the processing speed is 100 to 1100 m / min, preferably 300 to 1050 m / min, more preferably 450 to 1000 m. / Min. When it exceeds 1200 m / min, the frequency of the laminated continuous sheet S2 is increased, and in the chemical solution application process, uneven application of the chemical solution occurs due to the non-uniformity in the width direction of the lotion agent on the surface of the printing plate roll or anilox roll. There is a possibility that lotion will be scattered more.

In the manufacturing equipment or the manufacturing method of the secondary raw material roll for sanitary thin paper products according to the present embodiment, when the chemical solution is applied to both surfaces of the laminated continuous sheet S2, the total chemical solution application amount on both sides is 1.5 to 5. 0.0 g / m ² , preferably 2.0 to 4.5 g / m ² , more preferably 2.5 to 4.0 g / m ² . If it exceeds 5.0 g / m ² , the paper may be cut due to a decrease in paper strength or elongation, winding may occur when winding with a winding drum, or the quality may be too sticky. . If it is less than 1.5 g / m ² , the difference from the uncoated surface such as smoothness and moistness cannot be felt.

In addition, since there will be a difference between the front and back if there is a large difference in the coating amount on both coated surfaces, the coating amount on one side is preferably 20% or more and less than 50% of the whole. Since both coated surfaces are in contact with each other during the time (average between 8 hours and 24 hours) after being stored in the ply material after coating, the amount of both chemicals is gradually equalized. The front / back difference is improved.
When the chemical solution is applied only to one side of the laminated continuous sheet, the chemical solution is preferably applied to S1 because it is difficult to cause winding deviation. The coating amount is 1.5 to 5.0 g / m ² , preferably 2.0 to 4.5 g / m ² , more preferably 2.5 to 4.0 g / m ² .

[Multi-stand type inter folder]
A large number of secondary raw rolls R manufactured by the manufacturing equipment and manufacturing method for secondary paper rolls for tissue paper products described above are set in a multi-stand type interfolder, and the secondary raw rolls R are set to the secondary raw rolls R. A tissue paper bundle is manufactured by unfolding and folding the next continuous sheet. Hereinafter, an example of the multi-stand type interfolder will be described.

  2 and 3 show an example of a multi-stand type interfolder. Reference numeral 2 in the figure denotes secondary raw rolls R, R... Set on a secondary raw roll support portion (not shown) of the multi-stand type interfolder 1. The secondary raw rolls R, R... Are set side by side in a direction (the horizontal direction in FIG. 2 and the front-to-back direction in FIG. 3) perpendicular to the illustrated plane. Each secondary raw roll R has slits in the width of tissue paper product in the above-described manufacturing equipment and manufacturing method of the secondary raw roll for tissue paper products. It is wound and set in double width.

  The continuous belt-like secondary continuous sheets 3 </ b> A and 3 </ b> B unwound from the secondary raw roll R are guided by guide means such as guide rollers G <b> 1 and G <b> 1 and sent to the folding mechanism unit 20. Moreover, the folding mechanism part 20 is provided with the folding plate group 21 in which the required number of folding plates P, P ... are arranged in parallel as shown in FIG. For each folded plate P, guide rollers G2, G2 and guide round bar members G3, G3 for guiding a pair of continuous secondary continuous sheets 3A or 3B are respectively provided at appropriate positions. Further, below the folded plates P, P..., A conveyor 22 is provided that receives and conveys the laminated band 30 that is stacked while being folded.

  A folding mechanism using this type of folded plates P, P... Is a known mechanism, for example, from US Pat. As shown in FIG. 5, this type of folding mechanism folds each continuous secondary continuous sheet 3A, 3B... In the Z-shape and is adjacent to the adjacent secondary continuous sheet 3A, 3B. Stack the ends together.

  FIGS. 7 to 10 show in detail the portions of the folding mechanism 20 that are particularly related to the folded plate P. FIG. In the folding mechanism unit 20, a pair of continuous secondary continuous sheets 3A and 3B are guided for each folded plate P. At this time, the continuous secondary continuous sheets 3A and 3B are guided by the guide round bar members G3 and G3 while being shifted in position so that the side end portions do not overlap each other.

  A continuous secondary continuous sheet that is overlapped on the lower side when guided by the folded plate P is defined as a first continuous secondary continuous sheet 3A, and a continuous secondary continuous sheet that is overlapped on the upper side is a second continuous sheet. As shown in FIGS. 5 and 8, these continuous secondary sheets 3A and 3B are second continuous secondary sheets of the first continuous secondary continuous sheet 3A. The side end e1 that does not overlap the sheet 3B is folded back to the upper side of the second continuous secondary continuous sheet 3B by the side plate P1 of the folded plate P, and as shown in FIGS. The side end e2 of the continuous secondary continuous sheet 3B that does not overlap with the first continuous secondary continuous sheet 3A is folded downward so as to be drawn under the folded plate P from the slit P2 of the folded plate P. . At this time, as shown in FIGS. 5 and 10, the side end portion e3 (e1) of the continuous secondary continuous sheet 3A stacked while being folded in the upstream folded plate P is second from the slit P2 of the folded plate P. Are guided between the folded portions of the continuous secondary sheet 3B. In this way, each continuous secondary continuous sheet 3A, 3B... Is folded into a Z-shape and the side edges of adjacent continuous secondary continuous sheets 3A and 3B are crossed together. In some cases, when the top tissue paper is pulled out, the side edge of the next tissue paper is pulled out.

  As shown in FIG. 2, the laminated band 30 obtained by the multi-stand type interfolder 1 as described above is cut (cut) at a predetermined interval in the flow direction FL by the subsequent cutting means 41, and the tissue is cut. The tissue paper bundle 30a is stored in the storage box B in the subsequent equipment as shown in FIG. 6A. In the multi-stand type interfolder 1 as described above, the paper direction of the laminated strip 30 is the vertical direction (MD direction) along the flow direction FL, and the horizontal direction along the direction orthogonal to the flow direction. Direction (CD direction). For this reason, the direction of the paper of the tissue paper constituting the tissue paper bundle 30a obtained by cutting the laminated band 30 into a predetermined length is the extension of the folded portion of the tissue paper as shown in FIG. The vertical direction (MD direction) is along the existing direction, and the horizontal direction (CD direction) is along the direction orthogonal to the extending direction of the folded portion of the tissue paper.

FIG. 6B shows an example of a product in which the tissue paper bundle 30a is stored in the storage box B. A perforation M is provided on the upper surface of the storage box B, and a part of the upper surface of the storage box B is broken by the perforation M so that the upper surface of the storage box B is opened. The opening is covered with a film F having a slit at the center, and the tissue paper T can be taken out through the slit provided in the film F.
By the way, as described above, the direction of the paper of the tissue paper constituting the tissue paper bundle 30a is the horizontal direction (CD direction) along the direction orthogonal to the extending direction of the folded portion of the tissue paper. As shown in (b), when pulling out the tissue paper T from the storage box B, the pulling direction is along the lateral direction (CD direction) of the tissue paper T.

Next, an embodiment of the stock storage for storage according to the present invention is shown in FIGS. 14 to 17, and this embodiment will be described in detail with reference to these drawings.
The laminated continuous sheet S2 coated with the chemical solution as described above is wound around the winding core RM to form the secondary raw roll R. Then, as described above, the secondary material roll R is folded by a multi-stand type interfolder after being held for a predetermined time, and becomes a tissue paper containing a large number of products in the storage box B.

  In this case, first, as shown in FIGS. 14 and 15, the secondary raw rolls R are, for example, three rolls integrally arranged, sent out from the ply machine, and once sent into the raw stock storage 70 to be stored. Become so. The main body portion of the stock storage 70 is constituted by a storage main body 72 formed of a lightweight alloy made of aluminum or the like in a cylindrical shape with one end open so that the secondary raw roll R can be stored. ing. A lid member 76 formed in a disc shape that allows the storage body main body 72 to be opened and closed via a hinge 74 is attached to the open end side that is one end side of the storage body main body 72. The lid member 76 is also made of a lightweight alloy made of an aluminum material or the like, and is formed in the same manner as the storage body 72. Accordingly, the weight of the stock storage container 70 is suitable for stability and transportability. It is set appropriately.

  Further, as shown in FIG. 15, a main body side protruding portion 72 </ b> A having a screw hole 73 is formed in a portion opposite to the hinge 74 installed on one end side of the storage main body 72, and the lid member A lid-side projecting portion 76 </ b> A having a through hole 77 is formed in a portion opposite to the hinge 74 of 76.

  Therefore, when the lid member 76 is closed, they match each other, so that the lid member 76 and the storage body 72 are connected to each other as the bolt 80 shown in FIG. And the space K in the storage body 72 can be sealed. It should be noted that urethane for supporting the secondary raw roll R stored in the raw stock storage 70 is provided on the surface of the bottom wall 72B that forms the other end of the storage main body 72 and the surface of the lid member 76. Elastic support members 78A and 78B made of rubber and formed in a circular shape are respectively installed.

  A support base 82 having a structure capable of supporting the load of the storage body 72 and the secondary raw roll R is installed at the lower part of the storage body 72 while being connected to the storage body 72 by screwing or the like. . This support base 82 is formed of a material such as iron or aluminum, but the section of the support base 82 corresponding to the lower part on the back side, which is the other end side of the storage body 72, is supported in a rectangular shape. A pair of holes 82A formed deep into the table 82 are provided side by side in FIG. That is, a pair of forks of a forklift (not shown) can be inserted into the pair of holes 82A.

On the other hand, as shown in FIG. 17, the lower portion of the storage body 72 is a guide member for guiding when the secondary raw roll R is inserted into the storage body 72. The two free belts 84 are installed so as to be aligned with the lower part of the storage body 72.
These free belts 84 have a structure in which rotatable rollers 86 are arranged at both ends, and an annular belt material 88 made of a cloth material, a rubber material or the like is wound between the pair of rollers 86. It is not connected to a power source. For this reason, when the secondary web roll R is positioned between the pair of rollers 86, the belt material 88 is bent by its own weight, and the secondary web roll R is stabilized between them. Will be located.
In addition, a cushioning material can be provided inside the side surface inside the storage body. This is because the secondary web roll does not cause a large deformation even if there is a slight impact when the main body of the storage is transported or transported in the factory or lifted during storage.

The positions of these two free belts 84 are as follows.
That is, as shown in FIG. 17, each of the free belts 84 is oriented in a direction perpendicular to a line segment D extending from the center C of the secondary web roll R toward the center B1 in the width direction of the free belt 84. The plane of the material 88 is inclined. At this time, the angle A with respect to the perpendicular S extending from the center C of the secondary web roll R of the line segment D connecting the width direction center B1 of the free belt 84 and the center C of the secondary web roll R is 20 degrees. More preferably, the angle A is 30 degrees or more. The free belt can be installed in any number with any width, but it should be symmetrical so that the secondary web roll is stable.

  On the other hand, the stock storage case 70 according to the present embodiment is adjacent to the ply machine process by placing a support base 82 on a base 92 having legs 92A whose both ends extend downward in FIG. It is installed at a suitable position. A conveying belt 90 driven and rotated by a motor is located between the ply machine and the stock storage case 70.

  The transport belt 90 has a structure in which rotatable rollers 90A are disposed at both ends, and an annular belt material 90B made of a cloth material or a rubber material is wound around the pair of rollers 90A. . For this reason, when the driving force of the motor is transmitted to one of the rollers 90A, the belt material 90B is rotated as the roller rotates.

  Accordingly, when the secondary rolls R of three rolls are integrally arranged and sent out from the ply machine, they are placed on the conveyor belt 90 and placed on the side of the original stock storage 70 in the direction of the arrow H shown in FIG. The two free belts 84 guide the secondary raw roll R and feed it into the raw stock storage 70 for storage.

Next, the operation of the stock storage 70 according to the present embodiment will be described.
According to the original fabric storage 70 according to the present embodiment, a secondary original roll in which a laminated continuous sheet S2 that is a paper material is wound in a storage main body 72 formed in a cylindrical shape with one end opened. R can be stored, and when the secondary raw roll R is inserted into the storage body 72, the two free belts 84 arranged side by side at the lower part of the storage body 72 are Guide the next web roll R.

  Moreover, it has a lid member 76 that is formed in a disc shape and is attached to one end side of the storage body main body 72 so that the storage body main body 72 can be opened and closed, and when the lid member 76 is closed, the storage body main body 72. The inner space K can be sealed. Elastic support members 78A and 78B for supporting the secondary raw roll R are respectively installed on the bottom wall 72B and the lid member 76 that form the other end side of the storage body 72.

  Therefore, for example, after the material that has been wound after slitting and formed as the secondary material roll R is inserted into the storage body 72, the open portion for inserting the secondary material roll R of the storage body 72 is covered. By closing with the member 76, the space in the storage main body 72 is in a sealed state. When the secondary raw roll R is stored in the storage body 72 of the raw storage 70 as described above, the internal space is narrow, so that the secondary raw roll R hardly absorbs moisture from the outside air. As a result, not only does the winding slip hardly occur, but also deformation of the secondary raw roll R can be prevented.

  And according to this Embodiment, since a pair of hole part 82A is formed in the support stand 82 which exists in the part of the storage main body 72 used as the lower part of the two free belts 84, these one pair By inserting the pair of forks of the forklift into the holes 82A of the forklift, the pair of forks can be reliably supported at the portion directly below the center of gravity of the secondary roll roll R, and the stock storage 70 can be easily transported. It becomes.

  That is, after being inserted into the original fabric storage case 70, the secondary raw material roll R is moved by the forklift together with the original material storage case 70, and the lid member 76 is opened. The secondary fabric roll R taken out from the stock storage 70 can be attached to the stand-type interfolder. In this way, the secondary web roll R that can store the secondary web roll R is adopted, and the secondary web roll R is moved together with the stock web stock 70, so that the secondary web roll R can be stored. Is no longer required to be clamped, and the secondary roll R can be easily set in the multi-stand type interfolder.

  As described above, according to the original fabric storage 70 according to the present embodiment, since there is no need to hold the secondary original roll R with a clamp, deformation and scratches on the secondary original roll R are minimized. In addition, since it is in a hermetically sealed state, even when the secondary fabric roll R is stored for a long period of time, further moisture absorption is suppressed. It becomes difficult to do. As a result, even when the secondary roll R is temporarily stored in a warehouse or the like, the secondary roll R can be reliably prevented from being unwound and deformed, and can be easily post-processed. Quality will be improved.

  As a result of the above, it is possible to perform post-processing without any problem even with the secondary film roll R coated with the chemical solution, and for example, the secondary film roll R can be easily set in a multi-stand type interfolder. In this multi-stand type interfolder, stable operation becomes possible. Accordingly, the product coated with the chemical solution can be produced without waste, and the production quantity is improved, so that the manufacturing cost can be reduced.

On the other hand, according to the present embodiment, according to the shape of the secondary raw roll R, the storage body 72 is formed in a cylindrical shape as described above, and the lid member 76 is formed in a disk shape. The space in the stock storage 70 becomes a minimum area, and the amount of moisture absorption can be further suppressed.
Further, according to the present embodiment, the elastic support members 78A and 78B for supporting the secondary material roll R are not only installed on the bottom wall 72B and the lid member 76 of the storage body 72, but also the secondary material roll R. A guide member for guiding the original roll R is a free belt 84 that rotates as the secondary original roll R is inserted. By this, even when the original fabric storage container 70 is transported to move the secondary raw fabric roll R, it is protected by the elastic support members 78A and 78B and the free belt 84 serves as a cushion. Deformation and scratches on the secondary raw roll R accompanying conveyance are reduced.

  Furthermore, in the present embodiment, the center of the secondary web roll R of the line segment D connecting between the center portion B1 in the width direction of the two free belts 84 and the center C of the secondary web roll R shown in FIG. The angle A with respect to the perpendicular S extending from C is 20 degrees or more. That is, according to the present embodiment, not only the two free belts 84 serve as cushions, but also the free belt 84 located on the outermost side is inclined at an appropriate angle. A force toward the center is always generated by the free belt 84 against the secondary raw roll R. As a result, even when the original fabric storage container 70 is transported, the secondary original fabric roll R is further deformed without impacting the secondary original fabric roll R not only in the axial direction but also in the radial direction. It becomes difficult.

  In the above embodiment, the guide members are two free belts 84, but the number of free belts may be one or three or more. It is preferable that the angle A with respect to a perpendicular extending from the center of the line segment connecting the center in the width direction and the center of the sheet is 20 degrees or more.

  Furthermore, in the said embodiment, while the storage main body is formed in the cylindrical shape which opened one end, it is set as the structure where the cover member was formed in the disk shape, and was attached to the one end side of the storage main body. As in the above embodiment, it is not necessary to attach a lid member to the storage cabinet body via a hinge, and these are formed as separate bodies so that the storage cabinet body can be closed only when necessary Also good. A rubber packing or the like may be appropriately disposed between the storage body and the lid member.

In addition, these are formed in an elliptical shape in the above-described embodiment even in a cylindrical shape or a disk shape. However, they are not necessarily formed in a cylindrical shape or a disk shape, and may be formed in a polygonal cylindrical shape such as a quadrangle. Alternatively, it may be formed in a polygonal plate shape such as a quadrangle.
In addition, a plurality of convex portions are provided on one plane that is horizontal to the ground at the upper portion of the storage body, and a concave portion that is opposed to the upper convex portion is provided at the lower portion of the storage body. Alternatively, it can be stored in three layers.

  The present invention can be applied to conveyance of a secondary roll for tissue paper products to a multi-stand type interfolder.
