Abstract
The invention has purposes of increasing length of a wound body in a roll by efficiently using a space formed in a container and of improving strength as a unit by reducing the space.
In a roll (1) in which a wound body (2) is wound around a specified axis for plural times, a spacer (3) is provided in a portion of a region between turns of the wound body (2).
Description
- The invention relates to a roll and a method for manufacturing a roll.
- A roll that is configured by winding a belt-shaped wound body around a core material has widely been known. The wound body is wound in preset length, and the roll is then accommodated in a container.
- A shape of the roll depends on an outer peripheral shape of the core material, which serves as a mandrel for winding the wound body. However, no matter what shape the outer peripheral shape of the core material is, the roll is rounded as number of turns is increased. Thus, the shape of the roll eventually resembles a column (for example, see JP-A-2002-42854, JP-A-2003-157888).
- By the way, the container for accommodating the roll is sometimes formed in a columnar shape so as to correspond to a final shape of the roll and is the other times formed in a prismatic shape in consideration of stacking.
- Here, an outer edge of the container is formed in an arc shape. Thus, in the cases where the rolls are respectively accommodated in the columnar containers and the containers are aligned, a clearance is generated between the adjacent containers. This causes a problem of degraded space efficiency when plural units, each of which is configured by accommodating the roll in the container, are stacked.
- Meanwhile, when a
columnar roll 102 is accommodated in aprismatic container 101 as depicted inFIG. 14 , aspace 103 is formed between an inner wall of thecontainer 101 and theroll 102. This causes a problem of restriction in number of turns of theroll 102 despite availability of thespace 103 in thecontainer 101. The generation of thespace 103 in thecontainer 101 also leads to such a problem that sufficient strength cannot be retained when the units are stacked. - The invention has been made in view of the above problems and therefore has a purpose of providing a roll and a method for manufacturing a roll capable of increasing length of a wound body in the roll by efficiently using a space that is generated in a container and improving strength as a unit by reducing the space.
- In order to solve the above problems, the invention is a roll in which a wound body is wound around a specified axis for plural times, and is characterized in that a spacer is provided in a portion of a region between the wound bodies.
- The roll preferably has: plural corner sections that are bent by the spacers; and a linear section between two each of the corner sections.
- Mounting intervals of the spacers are preferably equally spaced intervals.
- The spacers are preferably provided at every 90° with the specified axis being a center when the roll is seen in a vertical cross section along a winding direction of the wound body.
- The spacers are preferably provided at every 60° with the specified axis being the center when the roll is seen in the vertical cross section along the winding direction of the wound body.
- The spacers are preferably provided at every 120° with the specified axis being the center when the roll is seen in the vertical cross section along the winding direction of the wound body.
- The spacer is preferably formed of curable ink or gel.
- The spacer is preferably formed of plastic.
- All of the spacers are preferably formed in the same size.
- At least some of the spacers are preferably formed in different size from the other spacers.
- The wound body is preferably a belt-shaped laminated body.
- The belt-shaped laminated body is preferably a power-generating element body that has a positive electrode sheet, a negative electrode sheet, and a separator that is arranged between the positive electrode sheet and the negative electrode sheet.
- The wound body is preferably a wire member.
- The invention is a method for manufacturing a roll and is characterized by including the steps of: feeding a wound body to a core material for winding the wound body; sequentially providing the spacers in advance at preset intervals on a surface of the wound body during feeding of the wound body; and sequentially winding the wound body, which is provided with the spacers, around the core material.
- The spacer is preferably formed when curable ink is injected onto the surface of the wound body and the ink is cured.
- The spacer is preferably formed when the spacer that is retained by a retainer is adhered to the surface of the wound body.

However, in the following embodiment, a description will be made by raising a case where the roll is a battery as an example.
-
FIG. 1 is a view in which the roll is seen from one end side in a winding axis direction. As depicted inFIG. 1 , aroll 1 is formed when awound body 2 is wound around a specified axis for plural times, thereby forming concentric laminations of thewound body 2. Theroll 1 includes thewound body 2 andspacers 3. The spacers are provided between adjacent laminations of thewound body 2. - The
wound body 2 is a belt-shaped laminated body that is formed in a thin plate shape, for example. This belt-shaped laminated body is formed as one sheet of a belt-shaped member, in which a positive electrode sheet, a negative electrode sheet, a separator that is arranged between the positive electrode sheet and the negative electrode sheet are laminated to make four layers. The belt-shaped laminated body functions as a power-generating element body of the battery. - The power-generating element body with specified capacity can be formed by winding this
wound body 2 around a winding roller (a core material) in predetermined length. - The
spacer 3 is provided on one surface of thewound body 2, and a plurality thereof is arranged in a portion of a region betweenadjacent wound bodies 2 in a thickness direction (a radial direction) of theroll 1. All of thespacers 3 are formed in the same size and mounted at equally spaced intervals. Thespacers 3 are not provided to cover the one entire surface of thewound body 2 but are provided at every 90° with a winding axis O being a center when theroll 1 is seen in a vertical cross section along a winding direction of thewound body 2, as depicted inFIG. 1 , for example. With such arrangement of thespacers 3, thespacers 3 are arranged linearly along the thickness direction of theroll 1 with thewound body 2 being interposed between two each of these. Lines L1, L2 for connecting centers of thespacers 3 become straight lines, thespacers 3 opposing each other with the winding axis O being interposed therebetween. These straight lines L1, L2 cross each other at right angles at the winding axis O. The region in thewound body 2 where thespacer 3 is provided has an increased curvature because only a corresponding portion is pushed outward by thickness of thespacer 3. Thus, the portion is brought into a slightly pointed state when compared to an arc. Accordingly, the four regions where thespacers 3 are arranged along the thickness direction are each formed as acorner section 21 that is bent and rounded by thespacers 3. By forming thiscorner section 21, the other region (a region that connects between the corner sections 21) in thewound body 2 serves as alinear section 22 that extends linearly. As a result, the substantiallysquare roll 1 with the fourcorner sections 21, which are not perfect corners, is formed. - The
spacer 3 is formed by injecting and curing curable ink onto the one surface of thewound body 2, for example. Note that thespacer 3 is not limited to the curable ink but may be a material in a gel form or another material such as plastic, metal, paper, fiber, ceramic, or rubber. In summary, any material can be used therefor as long as the curvature of thewound body 2 is changed when a space is formed between theadjacent wound bodies 2 in the thickness direction of theroll 1. - Next, a method for manufacturing the
roll 1 will be described.FIG. 2 is a view for explaining the method for manufacturing the roll, andFIG. 3 includes views for explaining shapes of the spacer. - As depicted in
FIG. 2 , thewound body 2 that is wound in a roll shape is pulled out from one end of thewound body 2, and thewound body 2 is fed to aroller 10 that serves as the core material for winding thewound body 2. When being fed to theroller 10, thewound body 2 extends linearly along a surface direction thereof and is fed. Thespacers 3 are provided on an upper surface of thewound body 2 in this feeding path. Thespacers 3 are formed when the curable ink in a liquid form is injected from anozzle 11 onto thewound body 2 and this ink is then cured. The curable ink can freely be selected from ultraviolet curable ink, thermosetting curable ink, and the like. - The ink is injected at preset time intervals, and the
spacers 3 can thus sequentially be provided on thewound body 2 at preset intervals. The intervals of thespacers 3 are determined in consideration of required intervals thereof in each turn such that thespacers 3 are arranged on the straight line along the thickness direction of theroll 1 when thewound body 2 is wound around theroller 10. - As depicted in
FIG. 3 , thespacer 3 may be formed linearly along a width direction (a short-side direction that crosses a longitudinal direction at right angles) of thewound body 2 that is formed in the belt shape (seeFIG. 3(a) ), or may be formed in a scattered manner at specified intervals along the width direction of the wound body 2 (seeFIG. 3(b) ). - The ink that is injected onto the
wound body 2 is cured before being wound around theroller 10, and thewound body 2, which is provided with thespacers 3, is sequentially wound around theroller 10. Thewound body 2 is wound around theroller 10 in such a state that constant tension is applied to thewound body 2. Thus, thewound body 2 is sequentially wound around theroller 10 while neither sagging nor a clearance is generated in theroll 1. However, due to the thickness of thespacer 3, a space is formed around thespacer 3 in the region where thespacer 3 is provided. As a result, the curvature of thewound body 2 is changed. - Next, a description will be made on an increase in total length of the
wound body 2, which is caused by provision of thespacers 3. -
FIG. 4 is an enlarged view of a portion of thewound body 2 at a time when thespacer 3 is not provided and thewound body 2 is wound.FIG. 5 is an enlarged view of a portion of thewound body 2 at a time when thespacer 3 is provided and curvatures of the surface in n turn and n+1 turn of thewound body 2 are the same.FIG. 6 is an enlarged view of a portion of thewound body 2 at a time when thespacer 3 is provided and the curvatures of the surface in n turn and n+1 turn of thewound body 2 differ. - As depicted in
FIG. 4 , a portion (a ¼ turn) of theroll 1 is cut out for consideration. When a radius up to an outer periphery of thewound body 2 in the n turn is set as r and thickness of thewound body 2 is set as t, length LN1 of the outer periphery of thewound body 2 in the n turn and length LN2 of the outer periphery of thewound body 2 in the n+1 turn are: -
LN 1=2πr/4 -
LN 2=2π(r+t)/4. - As depicted in
FIG. 5 , a case where thespacer 3 is provided between thewound body 2 in the n turn and thewound body 2 in the n+1 turn will be considered by cutting the portion (the ¼ turn) of theroll 1 as in a similar manner toFIG. 4 . Thewound body 2 is wound such that a radius of an arc portion of thewound body 2 in the n turn is equal to a radius of an arc portion of thewound body 2 in the n+1 turn, that is, curvatures thereof are equal to each other. In addition, a radius up to the outer periphery of thewound body 2 in the n turn is set as r and the thickness of thewound body 2 is set as t. In such a case, length LA1 of the outer periphery of thewound body 2 in the n turn and length LA2 of the outer periphery of thewound body 2 in the n+1 turn are: -
LA 1=2πr/4 -
LA 2=2πr/4+2t. - Here, when it is assumed that the length LA2 and the length LN2 described above have a relationship of LA2>LN2, this equation will be simplified as follows:
-
2πr/4+2t>2π(r+t)/4 -
2πr+8t>2πr+2πt -
8t>2πt -
(8−2π)t>0 -
1.7168t>0. - Here, because t>0, it is understood that this relationship is established.
- Thus, in the case where the
rolls 1 in the same number of the turns are compared, it is understood that the total length of thewound body 2 is increased when thespacers 3 are provided. - As depicted in
FIG. 6 , a case where thespacer 3 is provided between thewound body 2 in the n turn and thewound body 2 in the n+1 turn will be considered by cutting the portion (the ¼ turn) of theroll 1 as in the similar manner toFIG. 4 andFIG. 5 . Thewound body 2 is wound such that the arc portion of thewound body 2 in the n+1 turn has a smaller radius, that is, has a larger curvature than the arc portion of thewound body 2 in the n turn. In addition, a radius up to the outer periphery of thewound body 2 in the n turn is set as r1, a radius up to an outer periphery of the arc portion of thewound body 2 in the n+1 turn is set as r2, a linear portion that extends from each end of the arc portion of thewound body 2 in the n+1 turn is set as s, and the thickness of thewound body 2 is set as t. In such a case, length LB1 of the outer periphery of thewound body 2 in the n turn and length LB2 of the outer periphery of thewound body 2 in the n+1 turn are: -
LB 1=2πr 1/4 -
LB 2=2πr 2/4+2s. - Here, when it is assumed that the length LB2 and the length LN2 described above have a relationship of LB2>LN2 (where r1>r2, s=t+r1−r2), this equation will be simplified as follows:
-
2πr 2/4+2s>2π(r+t)/4 -
2πr 2/4+2(t+r 1 −r 2)>2π(r 1 +t)/4 -
2πr 2+8(t+r 1 −r 2)>2π(r 1 +t) -
2πr 2+8t+8r 1−8r 2>2πr 1+2πt -
8t−2πt>2πr 1−2rπ 2−8r 1+8r 2 -
(8−2π)t>(8−2π)r 2−(8−2π)r 1 -
t>r 2 −r 1 -
t−(r 2 −r 1)>0. - Here, because t>0 and r1>r2, it is understood that this relationship is established.
- Thus, in the cases where the
rolls 1 in the same number of the turns are compared and the curvature of thewound body 2 is increased, it is understood that the total length of thewound body 2 in theroll 1 is increased when thespacers 3 are provided. - According to the
roll 1 and the method for manufacturing theroll 1 as described so far, when thespacer 3 is provided between theadjacent wound bodies 2 in the thickness direction of theroll 1, only the portion of the region in thewound body 2 where thespacer 3 is provided is pushed outward for the thickness of thespacer 3. As a result, this region in thewound body 2 obtains the increased curvature and is brought into the slightly pointed state when compared to the arc. Accordingly, the four positions, at which thespacers 3 are arranged along the thickness direction of theroll 1, are each formed as thecorner section 21 that is bent and rounded by thespacer 3. By forming thiscorner section 21, the other region (the region that connects between the corner sections) in thewound body 2 serves as thelinear section 22 that extends linearly. As a result, the substantiallysquare roll 1 with the fourcorner sections 21, which are not the perfect corners, is formed. - In this way, as depicted in
FIG. 7 , when theroll 1 is accommodated in a generalprismatic container 4, thelinear section 22 substantially abuts against an inner wall of thecontainer 4. In addition, thecorner section 21 is pointed when compared to the arc. Thus, a dead space in thecontainer 4 is significantly reduced. Accordingly, theroll 1 suited for thecontainer 4 can be formed, and the length of thewound body 2 in theroll 1 can be increased by efficiently using the space formed in thecontainer 4. Furthermore, strength as a unit can be improved by reducing the space. Thus, theroll 1 is suited for stacking of the units. - Moreover, as described above, the total length of the
wound body 2 can be increased by providing thespacers 3 even when the number of the turns is the same. Thus, the capacity of the battery can be increased. - Note that the above embodiment has been described by raising the substantially square roll as the example. However, as will be described below, the roll may be formed in a substantially hexagonal shape or a substantially triangular shape.
-
FIG. 8 is a view in which a substantially hexagonal roll is seen from the one end side in the winding axis direction, andFIG. 9 is a view of a state where the substantially hexagonal rolls are respectively accommodated in containers and these units are stacked. - As depicted in
FIG. 8 ,spacers 3 a are provided at every 60° with the winding axis O being the center when aroll 1 a is seen in a vertical cross section along a winding direction of awound body 2 a. When thespacers 3 a are arranged just as described, thespacers 3 a are arranged linearly along a thickness direction of theroll 1 a with thewound body 2 a being interposed between two each of these. In addition, six positions, at which thespacers 3 a are arranged along the thickness direction, are each formed as acorner section 21 a that is bent and rounded by thespacers 3 a. By forming thiscorner section 21 a, the other region (a region that connects between thecorner sections 21 a) in thewound body 2 a serves as alinear section 22 a that extends linearly. As a result, the substantiallyhexagonal roll 1 a with the sixcorner sections 21 a, which are not perfect corners, is formed. - As depicted in
FIG. 9 ,such rolls 1 a are respectively accommodated incontainers 4 a in the same hexagonal shapes. In this way, when these units are stacked, a honeycomb structure is formed. Thus, the units can be arranged with no clearance, and the strength of the units can significantly be improved. -
FIG. 10 is a view in which a substantially triangular roll is seen from the one end side in the winding axis direction, andFIG. 11 is a view of a state where the substantially triangular rolls are respectively accommodated in containers and these units are stacked. - As depicted in
FIG. 10 ,spacers 3 b are provided at every 120° with the specified winding axis O being the center when aroll 1 b is seen in a vertical cross section along a winding direction of awound body 2 b. When thespacers 3 b are arranged just as described, thespacers 3 b are arranged linearly along a thickness direction of theroll 1 b with thewound body 2 b being interposed between two each of these. In addition, three positions, at which thespacers 3 b are arranged along the thickness direction, are each formed as acorner section 21 b that is bent and rounded by thespacers 3 b. By forming thiscorner section 21 b, the other region (a region that connects between thecorner sections 21 b) in thewound body 2 b serves as alinear section 22 b that extends linearly. As a result, the substantiallytriangular roll 1 b with the threecorner sections 21 b, which are not perfect corners, is formed. - As depicted in
FIG. 11 ,such rolls 1 b are respectively accommodated incontainers 4 b in the same triangular shapes. In this way, when these units are stacked, the units can be arranged with no clearance, and the strength of the units can significantly be improved. - Note that the invention is not limited to the above embodiment. The shape of the roll is not limited to the above examples. The above-described effects can be exerted as long as the roll is in a substantially polygonal shape with plural corner sections.
-
FIG. 12 andFIG. 13 are views, each of which depicts another example at a time when the spacers are provided on the wound body. - As depicted in
FIG. 12 , the following method may be used. When thespacers 3 are to be provided on thewound body 2, thespacers 3 are adhered in advance at preset intervals to a surface of a belt B in aspacer retainer 12 that is detachable from thewound body 2 while rotating. Then, the belt B is brought closer to thewound body 2 at specified timing, and thespacers 3 on the belt B are thereby adhered to thewound body 2. - In addition, as depicted in
FIG. 13 , the following method may be used. When thespacers 3 are to be provided on thewound body 2, thespacers 3 are provided in advance at specified preset intervals on the surface of thewound body 2 prior to feeding of thewound body 2 to theroller 10. Then, the pulled woundbody 2 is sequentially fed to and wound around theroller 10. - Furthermore, the invention is not limited to the cases where the spacers are provided during feeding of the wound body as depicted in
FIG. 2 andFIG. 12 . While the wound body is wound around the core material, the spacers may be inserted at preset intervals between the wound body in the n turn and the wound body in the n+1 turn that are adjacent to each other. - Moreover, the wound body has been described as the belt-shaped member. However, the wound body may be a wire member as being used for a coil. In this case, a rod member or a plate member is used as the spacer. Before the wound body is wound for n layers, the spacer is set on the winding axis, and the wound body is wound. Then, before the wound body is wound for n+1 layers, the new spacer is inserted on the n layer, and the wound body is wound. In this way, the invention can be achieved.
- The spacer does not have to be provided between two each of the adjacent wound bodies in the thickness direction, and a mounted position thereof can freely be changed. In addition, in regard to the size of the spacer, at least some of the spacers may be formed in different size from the other spacers. That is, positions where the spacers are provided and the size of the spacers can freely be changed in accordance with the shape of the container.
