JP 2002-283280 A

  However, the paper sheet for the elderly, children, and the handicapped who do not have enough force on the fingers is required to press and tear the paper sheet pulled out from the outlet against the cutting blade attached near the outlet. The cutting work was difficult.

  An object of the present invention is to provide a paper dispenser capable of easily cutting a paper sheet even for a user who does not have a finger strength.

The invention described in claim 1 is made in order to achieve the above object, and draws out the paper sheet to a desired length from an outlet provided in a casing that accommodates the long paper sheet. Then, in a paper dispenser capable of cutting out the paper sheet with a cutting blade attached in the vicinity of the outlet,
A pair of rotating discs configured to be rotatable about a rotation axis and spaced apart from the width of the paper sheet;
A paper fixing roll sandwiched between the ends of the pair of turntables;
A pair of connecting rods, one end of which is connected to the outer surface of the pair of rotating disks, and spaced apart from the width of the cutting blade;
A load transmission roll sandwiched between the other ends of the pair of connecting rods,
A passage space for allowing the paper sheet to pass between the paper fixing roll and the load transmission roll is formed,
When the paper sheet is pressed against the load transmission roll, the pair of turntables are rotated by the upward pressure on the load transmission roll, and the pair of turntables are interlocked with the rotation of the pair of turntables. The paper fixing roll moves in the direction of the cutting blade provided so as to pass between the load transmission roll and the load transmission roll, and pushes the paper sheet that has passed through the passage space against the cutting edge of the cutting blade It is configured to be fixed in a contact state.

The invention according to claim 2 is the paper dispenser according to claim 1, wherein the drive roll is provided above the pair of rotating disks and parallel to the paper fixing roll,
A paper presser roll that sandwiches the paper sheet in cooperation with the drive roll;
The driving roll rotates in a state where the paper sheet is sandwiched in cooperation with the paper pressing roll, thereby feeding the paper sheet downward.

  According to a third aspect of the present invention, in the paper dispenser according to the first or second aspect, the cutting edge of the cutting blade is recessed toward the paper fixing roll at a portion in contact with the paper fixing roll. A curved surface is formed.

  According to the first aspect of the present invention, a passage space for allowing the paper sheet to pass therethrough is formed between the paper fixing roll and the load transmission roll, and the pair of turntables are rotated by the upward pressure on the load transmission roll. The paper sheet is fixed in a state in which the paper sheet is pressed against the cutting edge of the cutting blade by the paper fixing roll moved in the direction of the cutting edge in conjunction with the rotation of the pair of rotary plates. It becomes easy to bite in and the paper sheet can be easily cut out even for a user who does not have a strong finger.

  According to the second aspect of the present invention, the paper roll is fed out in the downward direction by rotating the drive roll in a state of sandwiching the paper sheet in cooperation with the paper pressing roll. The leading end portion of the subsequent paper sheet can be fed out by a predetermined amount, so that the user can easily pull out the paper sheet the next time the paper sheet is pulled out.

  According to invention of Claim 3, since the curved edge is formed in the part which the cutting-edge of a cutting blade contacts with a paper fixed roll so that it may become concave toward a paper fixed roll, a paper fixed roll passes through space. When the paper sheet that has passed through is cut and fixed in a state where it is pressed against the cutting edge of the cutting blade, the area where the paper sheet is sandwiched can be widened, and the force to fix the paper sheet becomes stronger. Even for users who do not have force, the paper sheet can be cut out more easily. In addition, the leading edge of the paper sheet after being cut by the user warps the shape of the portion fixed by the paper fixing roll and the cutting edge of the cutting blade. When the sheet is pulled out, there is no possibility that the leading end of the paper sheet is caught by the cutting edge of the cutting blade, and the paper sheet can be pulled out easily.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, a roll towel dispenser containing a roll towel will be described as an example of the paper dispenser.

(First embodiment)
As illustrated in FIGS. 1 to 3, the roll towel dispenser 100 according to the first embodiment includes a storage body 11 that supports a long paper sheet (roll towel P), and two left and right side surfaces 11 a of the storage body 11. A roll towel P can be accommodated in a housing 1 having a lid 12 that is openably and closably connected by hinges 2 and 2 provided one by one at the lower part of 11a. The rear surface 11b of the storage body 11 is fixed to a wall surface such as a kitchen or a washroom. The lid body 12 can be opened and closed in the front direction (arrow direction X in the figure) by rotating about the hinge portion 2 as an axis. The user can freely load the roll towel P into the storage body 11 or remove the roll towel P from the storage body 11 by opening the lid body 12 in the front direction.
An outlet 3 is provided at the joint of the lower surface 11 c of the storage body 11 and the lower end portion 12 a of the lid body 12. The user can draw out the roll towel P accommodated in the housing 1 through the outlet 3 (see FIG. 1).

The storage body 11 rotatably supports a paper roll towel P wound in a roll shape by means of paper support portions 4, 4 provided one at each of the left and right side surfaces 11 a, 11 a.
In addition, inside the storage body 11, as shown in FIG. 2, a driving roll 51 provided below the front direction of the roll towel P (arrow direction X in the drawing) and a substantially horizontal direction in the front direction of the driving roll 51. The paper presser roll 52 provided on the disk, a pair of disk-like rotary discs 53 and 53 provided below the drive roll 51 and the paper presser roll 52, and the ends of the pair of rotary discs 53 and 53. The paper fixing roll 54, a pair of connecting rods 55, 55 connected at one end to the outer surfaces of the pair of rotating disks 53, 53, and a load transmission roll 56 sandwiched between the other ends of the pair of connecting rods 55, 55. And are provided.

The drive roll 51 is provided above the pair of rotary disks 53, 53, and is configured to be rotatable in the direction of arrow Z in the drawing in order to feed the roll towel P out of the housing 1 from the outlet 3. It is a roll and is rotated by a motor (not shown). The drive roll 51 is positioned in parallel with the paper fixing roll 54.
The paper presser roll 52 is a roll for guiding the roll towel P to move downward by sandwiching the roll towel P in cooperation with the drive roll 51. That is, the driving roll 51 is fed in a downward direction by rotating in the front direction (arrow direction Z in the figure) while the roll towel P is sandwiched in cooperation with the paper pressing roll 52. be able to.

The pair of turntables 53 and 53 are disk-shaped members configured to be rotatable around a rotation shaft 53a, and the turntables 53 and 53 are provided apart from the width of the roll towel P. .
The paper fixing roll 54 is a roll that moves so as to draw an arcuate locus along with the rotation of the pair of rotary plates 53, 53, and holds the roll towel P in cooperation with the cutting blade 57.
The pair of connecting rods 55, 55 are substantially rod-shaped members for connecting the pair of rotating disks 53, 53, the load transmission roll 56 and the cutting blade 57. The pair of connecting rods 55, 55 are preferably connected at a position substantially opposed to the position where the paper fixing roll 54 of the pair of rotating disks 53, 53 is sandwiched between the rotating shaft 53a.
The load transmission roll 56 is a roll for transmitting a load for rotating the pair of rotating disks 53 and 53 via the pair of connecting rods 55 and 55.
The cutting blade 57 is attached to the lid 12 so that the cutting edge is directed in the inner direction of the housing 1 (arrow direction Y in the drawing) from the vertical direction, and the roll towel P can be cut out. (See FIG. 5 described later). The cutting blade 57 is provided so as to pass between one end and the other end of the pair of connecting rods 55, 55, that is, between the pair of rotating disks 53, 53 and the load transmission roll 56 (FIG. 2). , 3). That is, the connecting rods 55 and 55 are provided apart from the width of the cutting blade 57. The cutting blade 57 is made of, for example, a metal such as iron, zinc, or stainless steel, or a resin such as ABS resin, but is not limited thereto. Further, the cutting blade 57 may be attached to the storage body 11.

  Further, as shown in FIG. 4A, for example, the cutting blade 57 has a depression angle α formed by a direction from the blade edge 57a to the blade edge 57b and the horizontal plane Z of 0 ° or more and less than 90 ° (0 ° ≦ α < 90 °). The safety of the user is ensured because the risk of the user's fingers coming into contact with the blade edge 57b is reduced by attaching the cutting blade 57 toward the internal direction of the housing 1 (arrow direction Y in the figure). Can do.

  Here, the depression angle α is set to 0 ° or more because when the cutting blade 57 is attached with the depression angle α being less than 0 ° (α <0 °), it becomes difficult to press the roll towel P against the cutting edge 57b. This is because it becomes difficult to cut P.

  Furthermore, for example, as shown in FIG. 4 (b), the blade edge 57b is warped upward, so that the roll towel P easily bites into the blade edge 57b when the roll towel P is cut off. It is possible to further suppress slipping.

Each structural member provided inside the storage body 11 has a positional relationship as shown in FIGS.
That is, the roll towel P drawn out downward by the rotation of the drive roll 51 passes through the passage space S formed between the paper fixing roll 54 and the load transmission roll 56.
The tip portion P1 of the roll towel P that has passed through the passage space S is drawn out of the housing 1 through an outlet 3 provided on the lower surface of the housing 1 (see FIG. 1).
The user can cut the roll towel P by pressing the desired position of the drawn roll towel P against the cutting edge of the cutting blade 57 and then pulling it upward.

  In addition, the paper sheet which concerns on this embodiment is manufactured by using only virgin pulp, waste paper pulp, or a mixture thereof as a paper stock, for example. When used paper pulp is used, 100% used paper pulp or virgin pulp may be blended. Moreover, the kind of pulp fiber is not particularly limited, but it is preferable to use softwood pulp in an amount of 60 to 100% by weight, particularly preferably 80 to 100% by weight, and a remaining amount of hardwood pulp. By making high-blend hardwood pulp with short fibers, the influence of fiber orientation is reduced, and easier and more precise tearing is possible.

The basis weight of the paper sheet can be, for example, about 15 to 65 g / m ² measured according to JIS P 8124 (1998), but in the case of 1 ply, the basis weight is 30 to 60 g / m ² . The basis weight of 30 to 50 g / m ² is particularly preferable. In the case of 2 plies, one having a basis weight of 15 to 30 g / m ² is preferable, and one having a basis weight of 15 to 25 g / m ² is particularly preferable.

  The paper sheet preferably has an aspect ratio of dry tensile strength defined by JIS P 8113 (1998) of 2.0 or less, particularly preferably 1.0 to 1.8. This aspect ratio can be adjusted by changing various papermaking conditions such as the jet wire ratio in the wire part. By keeping the aspect ratio (longitudinal / lateral) of the dry tensile strength low, the occurrence of longitudinal tearing is reduced and tearing closer to a straight line becomes possible.

  Further, the paper sheet preferably has a tensile elongation at break (longitudinal direction) defined by JIS P 8113 (1998) of 16% or less, and particularly preferably 13% or less. The tensile elongation at break can be adjusted by the degree of creping (so-called crepe rate). By keeping the tensile elongation at break low, it is possible to prevent the direction of the tearing force applied to the paper from changing irregularly due to the elongation of the paper, and to reduce the occurrence of tearing in the longitudinal and oblique directions.

  In a more preferred form, the paper sheet has a transverse tear strength of 65 gf or less as defined in JIS P 8116 (2000). The aspect ratio of the tear strength is preferably 0.75 or more, particularly 0.8 or more. The tear strength in the transverse direction can be adjusted by changing the blending of pulp, the degree of beating (freeness), the tensile elongation at break, and the like. If the transverse tear strength and the aspect ratio of the tear strength are within this range, not only will the force required for tearing be appropriate, but it will be difficult to apply unnecessary force in unnecessary directions, resulting in a more beautiful tear. Will be able to.

  The paper sheet is suitable for a roll-shaped product, particularly a roll-shaped paper towel, which is formed by rolling a paper sheet and tearing it along the lateral direction. In such a product, there is a form in which a plurality of paper sheets are used as one sheet, but in such a form, test values such as dry / wet tensile strength, tensile break elongation, and tear strength are in a single sheet state. Means a value.

Although this invention is not limited to a roll-shaped paper towel, For example, when setting it as a roll-shaped paper towel of about 30-40 g / m < ² > measured according to JISP8124 (1998), as a measuring method of paper thickness. , Measured under the conditions of JIS P 8111 (1998) using a dial thickness gauge (thickness measuring instrument) “PEACOCK G type” (manufactured by Ozaki Seisakusho), 140 to 220 μm, and wet tensile strength (JIS P 8135) 1998)) is preferably 500 to 1500 cN / 25 mm in the vertical direction and 200 to 100 cN / 25 mm in the horizontal direction, and the water absorption is 100 mm on a test piece placed on a net, and a container containing the whole net and water. The specimen was lifted after sufficient penetration of water into the specimen, and the mass of the specimen was measured after being left for 30 seconds. The mass at the time of drying was subtracted from this measured mass by 100 to obtain the amount of water absorption per 1 m ² . Is preferably from 100 to 200 g / m ^2, dry tensile strength (JIS P 8113 1998) is within a range satisfying the aspect ratio, the vertical direction 1400~3000cN / 25mm, the lateral is 600~1700cN / 25mm Is preferred.

  Next, in the roll towel dispenser 100 which concerns on 1st Embodiment, the operation | movement at the time of the roll towel P being cut off by a user is demonstrated, referring FIGS. 5 to 8 are cross-sectional views taken along line VV in FIG.

The tip part P1 of the roll towel P is in a state of being drawn out in the vicinity of the outlet 3 as shown in FIG. Usually, when the roll towel P is cut off by the user, the cut end (tip portion P1) of the roll towel P is located in the vicinity of the outlet 3.
Immediately after the roll towel P is cut off, the tip portion P1 of the roll towel P remains in the vicinity of the cutting blade 57, and when the user next pulls out the roll towel P, there is a possibility that the finger may be damaged in some cases. In consideration of the safety of the user, it is desirable that the front end portion P1 of the roll towel P is slightly extended during use. In the present embodiment, although not particularly illustrated, by providing a mechanism for automatically rotating the drive roll 51 after the roll towel P is cut out, the roll towel P is fed out by a predetermined amount. Moreover, it is good also as a mechanism in which a user rolls out the roll towel P automatically by a predetermined amount by holding a hand over the sensor which is not shown in figure.
The mechanism for rotating the drive roll 51 is not particularly limited. For example, the rotation of the drive roll 51 may be controlled by a manual drive motor or the like.

When the user pulls out the roll towel P in the front direction (arrow direction X in the figure), the roll towel P is pressed against the load transmission roll 56 as shown in FIG.
When the roll towel P is further pulled out by the user, an upward pressure is applied to the load transmission roll 56 as shown in FIG.
When upward pressure is applied to the load transmission roll 56, the pressure (load) is transmitted from the load transmission roll 56 to the pair of rotating disks 53 and 53 via the pair of connecting rods 55 and 55. The rotating disks 53, 53 start to rotate.

By rotating the pair of turntables 53, 53, as shown in FIG. 8, the load transmission roll 56 moves upward, and the paper is fixed between the ends of the pair of turntables 53, 53. The roll 54 moves in the direction of the cutting blade 57 so as to draw an arcuate locus.
The roll towel P is held between the moved paper fixing roll 54 and the cutting blade 57, and is fixed in a state where the roll towel P is pressed against the cutting edge of the cutting blade 57.

That is, when an upward pressure is applied to the load transmission roll 56, the pair of rotating disks 53, 53 rotate and move toward the cutting blade 57 in conjunction with the rotation of the pair of rotating disks 53, 53. The paper fixing roll 54 is fixed in a state in which the roll towel P that has passed through the passage space S is cut out and pressed against the cutting edge of the blade 57.
And by a user pulling the roll towel P in a state of being fixed by the paper fixing roll 54, it is torn and cut along the width direction from the portion pressed against the blade edge of the roll towel P. It becomes.

  Thus, in the roll towel dispenser 100 according to the first embodiment, the passage space S through which the paper sheet (roll towel P) passes is formed between the paper fixing roll 54 and the load transmission roll 56, and the roll towel P Is pressed against the load transmission roll 56, the pair of rotary disks 53, 53 are rotated by the upward pressure on the load transmission roll 56, and in conjunction with the rotation of the pair of rotary disks 53, 53, The paper fixing roll 54 moves in the direction of the cutting blade 57 provided so as to be inserted between the 53 and 53 and the load transmission roll 56, and the roll towel P that has passed through the passage space S is cut off. Because it is fixed in a state where it is pressed against the roll towel, it becomes easy to bite the blade edge into the roll towel P, and the roll towel P can be easily used even for a user who does not have strong fingers. It is possible to take Ri.

Moreover, the roll towel dispenser 100 which concerns on 1st Embodiment is drawn | fed out so that the roll towel P may go to the downward direction, when the drive roll 51 rotates in the state which pinched | interposed the roll towel P in cooperation with the paper pressing roll 52. Therefore, the tip end portion P1 of the roll towel P after being cut out can be fed out by a predetermined amount, so that the user can easily pull out the roll towel P the next time it is pulled out.
In addition, it is also possible to set it as the mechanism which automatically rolls out the predetermined amount of roll towel P by holding a hand over the sensor which is not shown in figure at the time of use.

(Second Embodiment)
The roll towel dispenser 200 according to the second embodiment differs from the roll towel dispenser 100 according to the first embodiment only in the shape of the cutting blade. Therefore, for simplification of description, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The cutting edge 58b of the cutting blade 58 of the roll towel dispenser 200 according to the second embodiment is directed to the paper fixing roll 54 at a portion in contact with the paper fixing roll 54 as shown in FIGS. 10 (a) and 10 (b), for example. A curved surface is formed to be concave. In the roll towel dispenser 200, for example, as shown in FIGS. 11 to 14, when the roll towel P is pressed against the load transmission roll 56, the pair of turntables 53 and 53 are rotated by the upward pressure on the load transmission roll 56. Then, in conjunction with the rotation of the pair of turntables 53, 53, the paper fixing roll 54 is directed in the direction of the cutting blade 58 provided so as to be inserted between the pair of turntables 53, 53 and the load transmission roll 56. Is moved and fixed in a state where the roll towel P is pressed against the cutting edge 58b of the cutting blade 58. In the present embodiment, since the curved surface is formed so as to be concave toward the paper fixing roll 54 in the portion of the cutting edge 58 that contacts the paper fixing roll 54, the paper fixing roll 54 and the cutting blade 58. When fixing the roll towel P with the blade edge 58b, the range in which the roll towel P is sandwiched can be widened, and the force for fixing the roll towel P can be increased. In order to maximize the contact area between the paper fixing roll 54 and the cutting edge 58b of the cutting blade 58, the curvature of the curved surface formed on the peripheral surface of the paper fixing roll 54 and the cutting edge 58b of the cutting blade 58 is matched. It is more preferable.

  Next, in the roll towel dispenser 200 which concerns on 2nd Embodiment, the operation | movement at the time of the roll towel P being cut off by a user is demonstrated, referring FIGS. 11 to 15 are cross-sectional views taken along line XI-XI in FIG.

As shown in FIG. 11, the front end portion P <b> 1 of the roll towel P is in a state of being drawn out near the outlet 3. Usually, when the roll towel P is cut off by the user, the cut end (tip portion P1) of the roll towel P is located in the vicinity of the outlet 3.
Immediately after the roll towel P is cut off, the tip portion P1 of the roll towel P remains in the vicinity of the cutting blade 58, and when the user next pulls out the roll towel P, there is a possibility that the finger may be damaged in some cases. In consideration of the safety of the user, it is desirable that the front end portion P1 of the roll towel P is slightly extended during use. In the present embodiment, although not particularly illustrated, by providing a mechanism for automatically rotating the drive roll 51 after the roll towel P is cut out, the roll towel P is fed out by a predetermined amount. Moreover, it is good also as a mechanism in which a user rolls out the roll towel P automatically by a predetermined amount by holding a hand over the sensor which is not shown in figure.
The mechanism for rotating the drive roll 51 is not particularly limited. For example, the rotation of the drive roll 51 may be controlled by a manual drive motor or the like.

When the user pulls out the roll towel P in the front direction (arrow direction X in the figure), the roll towel P is pressed against the load transmission roll 56 as shown in FIG.
When the roll towel P is further pulled out by the user, an upward pressure is applied to the load transmission roll 56 as shown in FIG.
When upward pressure is applied to the load transmission roll 56, the pressure (load) is transmitted from the load transmission roll 56 to the pair of rotating disks 53 and 53 via the pair of connecting rods 55 and 55. The rotating disks 53, 53 start to rotate.

As the pair of rotating disks 53 and 53 rotate, the load transmission roll 56 moves upward as shown in FIG. 14 and the paper is fixed between the ends of the pair of rotating disks 53 and 53. The roll 54 moves in the direction of the cutting blade 58 so as to draw an arcuate locus.
Then, the roll towel P is held between the moved paper fixing roll 54 and the cutting blade 58, and is fixed in a state where the roll towel P is pressed against the cutting edge of the cutting blade 58.

That is, when an upward pressure is applied to the load transmission roll 56, the pair of rotating disks 53, 53 rotate and move toward the cutting blade 58 in conjunction with the rotation of the pair of rotating disks 53, 53. The paper fixing roll 54 is fixed in a state in which the roll towel P that has passed through the passage space S is cut out and pressed against the cutting edge of the blade 58.
At this time, since the cutting blade 58 is formed so that the shape of the blade edge is fitted to the paper fixing roll 54, the range in which the roll towel P is sandwiched when the roll towel P is fixed can be widened.

And by a user pulling the roll towel P in a state of being fixed by the paper fixing roll 54, it is torn and cut along the width direction from the portion pressed against the blade edge of the roll towel P. It becomes.
The tip portion P1 of the roll towel P after being cut by the user is warped in the shape of the portion fixed by the paper fixing roll 54 and the cutting edge of the cutting blade 58, as shown in FIG. Accordingly, when the user next pulls out the roll towel P, the tip portion P1 of the roll towel P is not likely to be caught by the cutting edge of the cutting blade 58, and thus the roll towel P can be pulled out easily.

  As described above, the cutting edge of the cutting blade 58 of the roll towel dispenser 200 according to the second embodiment has a curved surface formed in a portion that contacts the paper fixing roll 54 so as to be concave toward the paper fixing roll 54. Therefore, when the paper fixing roll 54 cuts the roll towel P that has passed through the passage space S and is fixed in a state where it is pressed against the cutting edge of the blade 58, the range in which the roll towel P is sandwiched can be widened. Since the fixing force becomes stronger, the roll towel P can be more easily cut out even for a user who does not have a finger strength. In addition, the tip portion P1 of the roll towel P after being cut by the user warps the shape of the portion fixed by the paper fixing roll 54 and the cutting edge of the cutting blade 58, so that the user can When the roll towel P is pulled out, there is no possibility of the tip portion P1 of the roll towel P being caught by the cutting edge of the cutting blade 58, and the roll towel P can be pulled out easily.

  As mentioned above, although concretely demonstrated based on embodiment which concerns on this invention, this invention is not limited to the said embodiment, It can change in the range which does not deviate from the summary.

  For example, in the above embodiment, the driving roll 51 and the paper pressing roll 52 are provided. However, the present invention is not limited to this. For example, the paper support portions 4 and 4 may be configured to rotate automatically or manually, so that the tip portion P1 of the roll towel P after being cut out may be fed out by a predetermined amount.

  Moreover, in the said embodiment, although a pair of rotary disk 53,53 is comprised by the disk-shaped member, it is not limited to this. Any shape may be used as long as it can rotate around the rotation shaft 53a and can sandwich the paper fixing roll 54 or connect the pair of connecting rods 55, 55.

In the first embodiment, the shape of the cutting blade 57 is described by exemplifying the shape of the tip of the blade edge 57b as shown in FIGS. 4A and 4B. It is not limited to. For example, as shown in FIGS. 16 (a) to 16 (d), any shape can be used as long as the thickness is reduced toward the tip of the blade edge 57b and the roll towel P can be cut off. May be.
