Description

  The present invention relates to a dispenser for a roll paper towel obtained by winding a belt-shaped paper towel into a roll.

The roll paper towel dispenser has a support mechanism that rotatably supports the roll paper towel inside the housing, and a paper outlet that is unwound from the roll paper towel attached to the support mechanism is provided at the bottom of the housing. From the above, a necessary length is drawn out appropriately and can be cut.
As for the paper discharge mechanism, a paper discharge roller that nips a paper towel unwound from a roll paper towel according to a sensor is driven by power to automatically discharge the appropriate length (for example, Patent Document 7 below). There is known a type in which the paper towel is pulled out and pulled out appropriately.
For the one that automatically ejects the appropriate length automatically by the former sensor, the roll that is held inside is small compared to the type in which the user pulls out the paper towel as long as possible. There is a merit that paper towels are good and can be replaced less frequently.
However, if the appropriate length is automatically discharged, the discharge stops automatically when the appropriate discharge length is exposed from the discharge port, and the discharge speed is the performance of the drive roller drive. It is not suitable for scenes that require a large amount of paper towels at once.
For example, at sites such as food processing factories, semiconductor manufacturing factories, or hospitals where hand-washing work is required when entering or leaving the facility, many people are required at the beginning of work, lunch, general breaks, end of work, etc. Since this operation is performed at the same time, the dispenser of the above type that automatically discharges may have an insufficient paper discharge speed, which may cause a traffic jam waiting for hand-washing in a hand-washing place or the like.
In particular, the above-mentioned facilities may not be able to use their own hand towels in consideration of the hygiene of the facilities, and in this case, the above problem becomes particularly significant.

On the other hand, in the above facilities, etc., after wiping hands with a paper towel containing chemicals such as a disinfectant, further wiping with a normal paper towel, wiping with a paper towel containing chemicals with functions of disinfection and moisturizing, etc. Multiple hand wiping with a characteristic paper towel may be required.
Multiple dispensers may be installed to solve the above-mentioned problems of waiting for hand-wiping and wiping with different types of paper towels. It is often installed in a relatively narrow place on a nearby wall surface or the like, and a plurality of dispensers may not be installed from the viewpoint of the installation location.

On the other hand, since the dispenser for automatic paper discharge drives the paper discharge roller with electric power, there is a problem that power consumption must be taken into consideration. In particular, such a dispenser is often installed near a washstand in a restroom, near a water wall in a kitchen, etc., and there may be no commercial power supply in such a place. In battery drive, power saving is a very important issue.
Here, as shown in FIG. 17, the conventional dispenser X2 loosely fits the protrusions 135 and 135 to the openings on both ends of the paper tube 121 of the roll paper towel 102 as a support mechanism for rotatably supporting the roll paper towel 102. I support it. That is, the paper tube 121 is supported only by being placed on the protrusions 135 and 135 in a free state.
The support in this state is such that there is a large gap between the paper tube 121 and the protrusion 135, so that the roll paper towel 102 flutters when the roll paper towel 102 rotates as the roll paper towel 102 is discharged. Paper towels may be pulled in the opposite direction.
Therefore, in the dispenser that automatically discharges the appropriate length as described above, a load is applied to the discharge roller that nips the paper towel unwound from the roll paper towel at this time, and unnecessary power may be consumed.
In the dispenser that automatically discharges the appropriate length as described above, quick discharge is desired. However, in the conventional dispenser, the fluttering is promoted by increasing the rotation speed of the discharge roller in order to improve the discharge speed. As a result, the power consumption is further increased.
Furthermore, this type of paper towel dispenser is primarily intended to supply paper towels for wiping wet hands. Therefore, the hand may be wet when all the roll paper towels held in the dispenser are unwound. In the conventional dispenser X2, when replacing the roll paper towel, it was necessary to directly replace the roll paper towel with the body around which the paper was wound, so that the paper was wetted unnecessarily when the roll paper towel was replaced. There were also drawbacks.

"Outline of roll paper towel dispenser of this form"
The roll paper towel dispenser X1 of this embodiment is a roll paper towel for a roll paper towel in which a long strip of paper towel used for wiping skin such as hands and face, drip of ingredients, and wiping moisture is wound around a paper tube. It is a dispenser (hereinafter also simply referred to as dispenser X1).

The dispenser X1 includes a casing 1 whose material is a synthetic resin such as ABS resin or a metal material, and a roll paper towel 2 (hereinafter also simply referred to as roll paper 2) provided in the casing or a reference form. A support mechanism for rotatably supporting the roll paper towel unit 2u, and a paper discharge roller 4 that rotates in a state in which the paper towel 20 that is a free tip portion of the roll paper towel 2 unwound from the roll paper towel 2 is nipped. And a paper discharge port 40 for exposing the paper towel 20 fed out by the rotation of the paper discharge roller 4 to the outside of the housing. The paper discharge roller 4 is rotationally driven by a power drive source such as a motor.

Here, the dispenser X1 of the present invention has a roll paper 2 having a structure in which a plurality of cylindrical portions 22 around which a paper towel 20 is wound are arranged coaxially and spaced apart or a roll paper towel unit 2u of a reference form (hereinafter, simply referred to as a roll paper unit 2u). Used).

By using the roll paper 2 or the roll paper unit 2u of the reference form, a plurality of paper towels 20 and 20 can be discharged from the paper discharge port 40 even with a single dispenser. Different types of paper towels 20, 20 constituting the portions 22, 22, for example, lotion-coated paper towels and non-lotion-coated paper towels, can discharge different types of paper towels at a time.

First, specific examples thereof will be described with respect to first and second embodiments of the roll paper towel 2 and embodiments of the roll paper unit 2u of the reference embodiment . In each example, the cylindrical portion 22 has two forms, but it may be more than that.

  However, the total length of the roll paper 2 or the roll paper unit 2u, that is, the distance L1 between both ends in the axial direction is preferably 333 to 710 mm so as not to disturb the compactness of the dispenser X1.

“First example of roll paper towel”
In the first embodiment of the roll paper towel 2 of the present invention, as shown particularly in FIG. 7, two long and belt-like paper towels 20 and 20 are separated by a predetermined distance between both ends of one paper tube 21. It is wrapped around. Accordingly, the cylindrical portions 22 and 22 around which the paper towels 20 and 20 are wound share a single paper tube 21, and further have a separating portion 25 between the cylindrical portions 22 and 22. Further, both end portions 21 </ b> P of the paper tube 21 protrude from the cylindrical portion 22 and are exposed. That is, in the roll paper 2 of this embodiment, the paper tube 21 is exposed at the both end portions 21P and 21P and the separation portion 25.

  As described above, in the illustrated embodiment, two long and belt-like paper towels 20 and 20 are wound around one paper tube 21 and the cylindrical portions 22 and 22 are in two forms. However, the present invention is not limited to this, and three or more paper towels may be wound around and three or more cylindrical portions may be provided.

  In the dispenser X1 of the present invention, the protruding portions 21P and 21P protruding and exposed of the paper tube 21 of the roll paper 2 are supported so as to be supported.

  Here, it is desirable that the distance of the separating portion 25, that is, the distance L2 between the adjacent cylindrical portions 22 and 22 is 3 to 20 mm from the viewpoint of the relationship with the interposition portion 19 described later and the compactness of the dispenser X1.

The inner and outer diameters, materials, and structures of the paper tube 21 may employ a conventionally known paper tube configuration, but the outer peripheral surface is preferably smooth. As a specific example, the outer diameter of the paper tube is 30 to 45 mm, and the material is coated cardboard. The structure is a structure in which a long paper tube base paper is wound (the same applies to the second embodiment and the roll paper unit). The basis weight of the paper tube constituting the paper tube is preferably 500 to 900 g / m ² from the viewpoint of maintaining strength and not being crushed when the protruding portion is grasped by hand. In addition, the paper tube is usually formed by laminating two to three paper tube base papers in a spiral shape, and the basis weight here means the total of the US basis weights of the paper tube base papers.

  On the other hand, the size of the cylindrical portion 22 of the roll paper 2, that is, the diameter L3 and the width L4, can be the size of a known roll paper towel (also in the following second embodiment and roll paper unit embodiment). The same). Specifically, the diameter L3 is about 110 to 250 mm and the width L4 is about 150 to 300 mm. When the diameter L3 is less than 110 mm, it is difficult to roll a sufficiently thick paper for a necessary length. On the other hand, when the diameter exceeds 250 mm, it is difficult to make the dispenser compact, and the weight increases, and the burden on the support mechanism and the separation portion increases, which is not desirable. Further, since the width L4 is also the width of the paper towel, if it is less than 150 mm, it is difficult to obtain a paper width necessary for wiping, and if it exceeds 300 mm, it is difficult to obtain a compact dispenser. In particular, the roll paper 2 according to this embodiment has a structure in which both end portions 21P and 21P of the paper tube 21 protrude from the end face of the cylindrical portion 22. Therefore, when the width exemplified above is exceeded, the compactness of the dispenser is extremely deteriorated.

  Here, the protruding length L5 at both ends of the paper tube 21 in the present invention is preferably about 10 to 15% of the width of one cylindrical portion 22. As a concrete numerical value, it is good to set it as 15-45 mm. Within such a range, the roll paper 2 can be sufficiently supported by the support mechanism described later, and the paper width is set to a width suitable for the use surface without deteriorating the compactness of the dispenser X1. it can.

  In addition, the raw material of a crepe paper which comprises the paper towel 20, a raw material, a physical property, etc. are not limited in this invention. A conventionally well-known thing can be suitably employ | adopted in the range which does not inhibit the effect of this invention. Preferred specific examples are as follows.

  The paper towel which is a constituent material of the roll paper of the present invention can be produced using only virgin pulp, waste paper pulp, or a mixture thereof as a stock. When used paper pulp is used, 100% used paper pulp or virgin pulp may be blended. Although the kind of pulp fiber is not particularly limited, 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 the paper towel exposed from the paper discharge port can be torn easily and densely.

It can be a 15~65g / m ² about paper towels, among them the basis weight thereof is preferably thick 30 to 60 g / m ^2, in particular basis weight preferably from 30 to 50 g / m ^2.

  Moreover, it is preferable that the aspect ratio of the dry tensile strength prescribed | regulated to JISP8113 (1998) is 2.0 or less, and, especially a paper towel is 1.0-1.8. 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 vertical tearing (tearing in the winding direction) when cutting the exposed part from the paper exit is reduced, making it more linear Tearing is possible.

  Further, the paper towel preferably has a tensile breaking elongation (winding direction, usually the vertical direction) as defined in 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, the direction of the tearing force applied when the paper towel exposed from the paper exit is cut off is prevented from changing irregularly due to the elongation of the paper towel itself, and unintended longitudinal or oblique tearing occurs. Can be reduced.

  The paper towel preferably 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. When the tear strength in the lateral direction and the aspect ratio of the tear strength are within this range, not only will the force required for tearing be appropriate when cutting the paper towel exposed from the paper outlet, but also in the direction where unnecessary force is unnecessary. It becomes difficult to act on, and it becomes possible to tear more beautifully.

Further, when the paper towel has a basis weight measured according to JIS P 8124 (1998) of about 30 to 40 g / m ² , the paper thickness is a dial thickness gauge (under the conditions of JIS P 8111 (1998)). Thickness measuring device) It is desirable that the thickness is 140 to 220 μm in a value measured using “PEACOCK G type” (manufactured by Ozaki Seisakusho).

Moreover, as for the paper towel, the specific numerical value of the 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.

Further, paper towels, water absorption, preferably from 100 to 200 g / m ^2. In addition, the water absorption here refers to a test piece cut into a 100 mm square, placed on a net, floated in a container containing water together with the net, pulled up after sufficient penetration of water into the test piece, and left for 30 seconds. It is the water absorption per 1 m ² calculated by measuring the mass of the test piece and subtracting the mass at the time of drying from this measured mass by 100.

  The paper towel preferably has a dry tensile strength (JIS P 8113 1998) in the range satisfying the above aspect ratio, and the longitudinal direction is 1400 to 3000 cN / 25 mm and the lateral direction is 600 to 1700 cN / 25 mm.

The values such as the dry tensile strength, tensile elongation at break, and tear strength mean values in a single sheet.
It should be noted that the types of paper towels constituting the plurality of cylindrical portions 22 may be different. In this case, for example, if one of them is provided with a chemical solution, the application method, the applied chemical solution, and the application amount are not limited. A known configuration can be employed.

"Second example of roll paper towel"
In the second embodiment of the roll paper towel 2 of the present invention, as shown in FIG. 8 in particular, two long and belt-like paper towels 20 and 20 are predetermined in one paper tube as in the first embodiment. It is wound at intervals. In addition, the cylindrical portions 22 and 22 around which the paper towels 20 and 20 are wound share one paper tube 21, and have a separating portion 25 that separates the cylindrical portions 22 and 22 from each other.

The difference from the first embodiment is that in this embodiment, both end portions of the paper tube 21 do not protrude from the cylindrical portion 22 and are not exposed. The configurations of the paper tube 21 and the cylindrical portion 22 are the same as in the first embodiment.
In the second embodiment, the following support shaft 5 is used for supporting the dispenser X1.

(Support shaft)
The support shaft 5 is inserted into the paper tube 21 and is longer than the length of the paper tube 21 and is cylindrical or columnar. The length of the support shaft is preferably the same as the full length (full width) L1 of the roll paper 2 in the first embodiment. Thereby, the compactness of dispenser X1 is maintained.

In the dispenser X1 of the present invention, the portion 5P of the support shaft 5 that is inserted through the paper tube 21 of the roll paper 2 and protrudes from both ends of the paper tube 21 and is exposed is supported.
Therefore, the protruding length L6 of the support shaft 5 from both ends of the paper tube 21 is the same as the protruding length L5 of the both ends 21P of the paper tube 21 in the first embodiment, and is 10 times the width of the cylindrical portion 22. It is good to set it as 15 to 45 mm with a specific numerical value of ~ 15%. Within this range, the roll paper 2 can be sufficiently supported by the support mechanism, and the paper width can be set to a width suitable for the use surface without deteriorating the compactness of the dispenser X1.

Further, when the support shaft 5 is inserted into the paper tube 21 and the paper towels 20 and 20 wound around the paper tube 21 are pulled out, there is a margin between the support shaft 5 and the paper tube 21. Since the roll paper 2 flutters, the outer diameter of the support shaft 5 is preferably close to the inner diameter of the paper tube 21 in consideration of this point. Specifically, it is desirable to be within 2 mm.
Furthermore, the material of the support shaft 5 is formed of a hard material that does not easily bend or bend, and specific examples include metals and hard plastic materials.

" Reference example of roll paper towel unit that can be used in the dispenser of the present invention "
As shown in FIG. 9 , the roll paper towel unit 2u according to the reference embodiment has a cylindrical portion that is a rolled portion of the paper towel 20 in which one long and strip-shaped paper towel is wound around one paper tube 21. A roll paper 2t having a general structure in which both ends of the paper tube 21 and both ends of the paper tube 21 coincide (this roll paper is hereinafter also referred to as a unit roll paper 2t) is coaxially connected via the characteristic connecting member 6 described below. It is formed by connecting a plurality of pieces apart. The illustrated form is an example in which two unit roll papers 2t are connected.

The connecting member 6 has both ends 60, 60 having a coaxial cylindrical shape, and at least both ends 60, 60 have the same or slightly smaller diameter than the inner diameter of the paper tube 21. A plurality of unit roll paper towels 2t and 2t are coaxially connected by inserting both end portions 60 and 60 of the connecting member 6 into the paper tubes 21 of the different unit roll papers 2t and 2t.
The outer diameters of both end portions 60, 60 may be designed to be different depending on the unit roll papers 2t, 2t having different paper tube inner diameters.

  Here, it is desirable that the outer diameters of both end portions 60 and 60 inserted into the paper tube 21 of the connecting member 6 and the inner diameter of the paper tube 21 are completely coincident with each other, but it is preferable that the outer diameter is approximately 0 to −1 mm. If the outer diameter of the portion 60 to be inserted is excessively smaller than the inner diameter of the paper tube 21, the risk of unintentional detachment after connection increases.

  Further, in order to prevent the separation, the lengths of the both ends 60 to be inserted are the same as the length of the unit roll paper 2t (in this embodiment, the length of the cylindrical portion 22 of the unit roll paper 2t, It is desirable that the width is 5 to 10% (specifically 15 to 45).

  On the other hand, the connecting member 6 according to the present embodiment includes stopper portions 61 and 61 provided so as to protrude to the outer surface between both end portions 60 and 60 inserted into the paper tube 21 of the unit roll paper 2t. Yes. The stopper portions 61 and 61 prevent the unit roll papers 2t and 2t from moving in the contact direction, and prevents the end portion 60 from being excessively inserted into the paper tube 21. The illustrated embodiment is an example in which two of the stopper portions 61 and 61 are formed apart from each other in order to securely hold the separation distance between the unit roll papers 2t and 2t. The same effect can be obtained by increasing the length (thickness).

In addition, a cylinder having the same diameter as the outer diameter of the paper tube 21 or the same diameter as the both end portions 60 and 60 inserted into the paper tube 21 is provided between the two stopper portions 61 and 61 in relation to the intervening portion 19 described later. It is desirable that Moreover, it is desirable that the separation distance between the stopper portions 61 and 61 is 3 to 20 mm.
The stopper portion 61 is preferably disk-shaped as in the illustrated example from the viewpoint of preventing excessive insertion and preventing shaking during rotation of the roll paper unit 2u.

On the other hand, the paper towel unit 2u according to the present reference embodiment is also supported in the dispenser X1 using the support shaft 5 in the same manner as the second form of the roll paper towel 2. In the dispenser X1 of the present invention, the support shaft 5 is inserted through the paper tubes 21 and 21 of the unit roll papers 2t and 2t of the roll paper unit 2u and the connecting member 6 so as to pass through the roll paper unit 2t. It supports so that the part of the support shaft 5 which protrudes from both ends and is exposed may be supported.

  Accordingly, the length of the support shaft 5 in this embodiment is from the end face of the roll paper unit 2u, that is, from both ends of the non-connecting side where the connecting members of the plurality of cylindrical portions 22 (similar to the unit roll paper 2t) are not inserted. The protruding length is assumed. The protruding length L6 is the same as in the second embodiment. The material and other configurations are as described in the second embodiment.

  In addition, when two unit roll papers are connected using the connecting member 6 in this way, the unit roll paper 2t is not limited to one having a paper tube, but instead of the paper tube, the winding butt is replaced with water or water. A so-called coreless unit roll paper having an air core portion hardened with water-decomposable glue can be used. In that case, what is necessary is just to insert the edge part 60 of the connection member 6 in the said air-core part.

“Example of housing structure”
On the other hand, as shown in FIGS. 1 to 6 in particular, the housing 1 is composed of a case body 10 with an open front surface and a lid body 11 covering the front surface opening portion of the case body 10.

In this case, the locking projection and the locking fitting hole may be paired, and it does not matter which is on the case body side.

  On the other hand, the paper discharge port 40 at the bottom of the housing can be formed in the bottom plate portion 13 of the case body 10. In the illustrated example, the front side of the bottom plate portion 13 of the case body 10 is inclined toward the top plate portion 12 side. In the inclined portion, an elongated discharge port 40 is formed in the width direction so that the user can easily take out the paper towel.

  Further, in the illustrated example, as shown particularly in FIG. 5, a cutter blade 40 c is attached so as to partially cover the paper discharge port 40 in order to easily cut out the paper towel exposed from the paper discharge port 40. . In the illustrated example, the cutter blade 40c is a saw blade. The cutter blade 40c can be formed of metal or a hard plastic resin.

"Example of support mechanism"
On the other hand, as shown in FIGS. 5, 6, 11, and 12, the support mechanism housed in the housing 1 is respectively arranged from the vicinity of both side plates of the back plate portion 14 to the front plate side (at the time of wall mounting). A pair of arm portions 31, 31 extending a predetermined length toward the front side), and support portions 32, 32 are attached to the tips of the arm portions 31, 31. In addition, not only the example of illustration but the arm parts 31 and 31 may be the aspect extended so that it may protrude in the horizontal direction from the side plate part 15, and are the aspects which hang down from the top-plate part 12. Alternatively, it may stand up from the bottom plate portion 13 toward the top plate portion 12. As long as the arm part 31 can position the support part 32 in the predetermined position in the range which does not prevent the effect of this invention, the specific aspect is not limited.

  FIG. 11 is an example of supporting the first form example of the roll paper 2, and the support form of the second form example and the form example of the roll paper unit is supported only by changing the paper tube to the support shaft. Since the aspect is the same, it is only explained and not shown.

  Here, the dispenser X1 of the present invention is characterized in that the support portions 32, 32 are respectively located on the back plate portion side and the front plate portion side in a state in which the lid is closed and parallel to the back plate portion. A pair of convex pieces 33, 33 standing in parallel toward the top plate side), and a receiving surface 34 between the convex pieces 33, 33 for receiving the protruding portion 21P of the paper tube 21 or the protruding portion 5P of the support shaft 5. And a trunk surface (circumferential surface) of the projecting portion 21P of the paper tube 21 or a trunk surface (circumferential surface) of the projecting portion 5P of the support shaft 5. By mounting on the receiving portion 30, both end portions in the width direction of the roll paper 2 or roll paper unit 2u are rotatably supported.

  As a preferred example, the receiving portion 30 is smooth between the convex pieces 33 and 33 from the top portion 33t of one convex piece 33 toward the top portion 33t of the other convex piece 33 via the receiving surface 34 as shown in the figure. The curved surface is a circular arc surface or a semi-cylindrical surface, and the paper tube 21 or the support shaft 5 is configured to smoothly slide and rotate. Further, the radius of curvature of the curved surface is made substantially equal to the radius of the cross-sectional circle of the paper tube 21 or the radius of the cross-sectional circle of the support shaft 5, and the paper tube 21 or the support shaft 5 rotates to the receiving portion 30. The paper tube 21 or the support shaft 5 is fitted between the convex pieces 33 and 33 when the roll paper 2 and the roll paper unit 2u are rotated.

  In the dispenser X1 of the present example having the support mechanism having the above-described configuration, the protruding portion 21P of the paper tube 21 or the protruding portion 5P of the support shaft 5 is supported by the receiving portion 30 at both ends in the width direction of the roll paper 2 or the roll paper unit 2u. Is supported. In such a support mechanism, flapping during rotation of the roll paper 2, 2 u is prevented by the support by the receiving portions 30, 30. Accordingly, when the paper discharge roller 4 is driven with the paper towel unwound from the roll paper 2 or the raw paper unit 2u being nipped, the load on the paper discharge roller 4 is reduced, and the power consumption of the drive source is reduced. can do.

"Eject mechanism"
On the other hand, the dispenser X1 of the present invention has a discharge roller 4 below the support portions 32 and 32 (on the bottom plate side), as can be understood from FIGS. 5 and 15 in particular. An example of the paper discharge roller 4 is a rod-shaped rotating shaft 41 having an axis parallel to the axis when the roll paper 2 or the roll paper unit 2u is supported and attached by a support mechanism, and an appropriate outer periphery thereof. And a rubber roll portion 42 provided at the position. Then, a plurality of paper towels 20 and 20 unwound from the cylindrical portions 22 and 22 of the roll paper 2 or the roll paper unit 2 u together with the pair of nip means 43 are simultaneously sandwiched. In the drawing, both end support portions of the paper discharge roller 4 and the nip roller 43 are not shown. A well-known support mechanism can be adopted for the both end support portions. The nip means 43 includes a rubber nip roll paired with the rubber roll portion 42 or a pressing means such as a pressing spring attached to the front plate of the housing so as to press the paper towel against the paper discharge roller 4. (This form is not shown).

  Here, in the dispenser X1 of the present invention, the rotating shaft 41 is rotated by a driving source 70 driven by power supply from a power source 75 such as a known motor means, and the discharge roller 4 is driven by power. It is said that. Note that the shaft of the motor means 70 and the rotating shaft do not have to be coaxial, and as illustrated in FIG. 15, the rotation is performed by appropriately interposing known mechanisms such as gears 72 and 72, an endless belt 73, and a pulley 74. The shaft 41 may be rotated.

  On the other hand, the motor means 70 is driven and stopped in response to a signal detected by sensor means provided near the paper discharge port on the outer surface of the bottom plate portion 13. For example, when an optical sensor such as an infrared ray is brought to the above position and a hand is brought close to the paper discharge port, the optical sensor detects this and causes the motor means 70 to drive the motor means 70 for a predetermined time. In this way, the paper towels 20 and 20 are exposed from the paper discharge port 40 by the amount of rotation of the paper discharge roller according to the drive time of the motor. The driving and stopping of the motor means is not limited to that by the above-described sensor means. In addition, sensor means for detecting the amount of rotation of the cylindrical portion 22 can be adopted, and a paper discharge mechanism using a conventionally known sensor means can be adopted.

  In the dispenser X1 of the present invention described above, the rotary shaft 41 is rotated by the motor means or the like while the paper towels 20 and 20 are nipped by the paper discharge roller 4 and the nip roll 43, and a plurality of (two in the illustrated form). The paper towels 20 and 20 are simultaneously exposed from the paper discharge port 40. At this time, the roll paper 2 or the roll paper unit 2u is rotated as the paper is discharged. Therefore, when the roll paper 2 or 2u flutters at this time, the paper towel instantaneously moves in the direction opposite to the paper discharge direction (winding direction), and as a result, acts to prevent forward rotation of the rotating shaft. Although the load for rotation increases and power consumption increases, in the dispenser X1 of the present invention, roll paper or the like is formed by the configuration of the characteristic roll paper 2, the roll paper unit 2u, and the support portions 32 and 32. Since there is no flapping, no load that increases power consumption is applied to the paper discharge roller 4. Therefore, the dispenser X1 of the present invention has low power consumption.

Further, since such flapping is prevented, the rotational speed of the paper discharge roller 4 can be increased, and the paper can be discharged quickly.
Furthermore, a plurality of paper towels can be simultaneously discharged from the paper discharge port, so that the rotation rate of the user can be increased and the type of paper towel 20 can be made different.

`` Intervening part ''
On the other hand, when the roll paper towel dispenser X1 of the present invention supports the roll paper 2 or the roll paper unit 2u on the support portions 32 and 32 as shown in FIGS. It has the characteristic interposition part 19 located in the space | interval part 25 between the cylindrical parts 22 and 22 which adjoin the roll paper 2 or the roll paper unit 2u.

In FIGS. 11 and 12, the interposition part 19 is provided in the lid body 11 constituting the housing 1, and when the entire open portion of the case body 10 is closed by the lid body 11, the back plate of the housing 1 is provided. It is the protrusion formed so that it may protrude in the part side.
The interposition part 19 can ensure the positioning between the support parts 32 and 32 even when a roll paper having a plurality of cylindrical parts 22 and 22 is used.

  In particular, when the interposition part 19 is provided in the lid body 11 as shown in FIGS. 11 and 13, the lid body 11 cannot be closed unless the interposition part 19 is positioned at the separation part 25, so that reliable positioning can be performed. It becomes like this.

  Further, as the roll paper 2 or the roll paper unit 2u is rotated when the paper towels 20 and 20 are pulled out from the respective cylindrical portions 22 and 22, the roll paper 2 or the roll paper unit 2u is prevented from shaking in the axial direction. The Thereby, flapping of the roll paper 2 or the roll paper unit 2u is further prevented, and the power consumption of the dispenser X1 can be further reduced.

  Furthermore, the contact between the paper towels 20 and 20 drawn out from the cylindrical portions 22 and 22 in the housing 1 is also prevented, and the roll paper 2 and 2u can be smoothly rotated. Can be further reduced.

  Here, in the example shown in FIGS. 11 and 13, the interposition part 19 is provided on the lid body 11, but it is formed so as to protrude from the back plate part 14 of the case body 10 to the front plate part 16 side. May be.

  For example, the interposition part 19 can be made of resin, metal, etc., and can be formed by attaching a piece-like member to the front plate part or the back plate part by bonding or the like. It can be integrally formed.

Furthermore, in the form of FIG. 11 and FIG. 13, the interposition part is simply located at the separation part 25, but as shown in FIG. 14A, the roll paper 2 or the roll paper unit 2u is supported by the support part. In a state of being supported by 32, 32, the paper tube 21 exposed between the cylindrical parts of the roll paper 2, 2u or the connecting member 6 is configured to contact and rotate from below to be supported rotatably. May be. If it does in this way, folding of the exposed part of the paper tube 21 which becomes weak in the roll paper which has a plurality of cylindrical parts will be prevented. Further, when the roll paper unit 2u is used, a portion of the connecting member 6 where the axis of the unit roll paper 2t, 2t is likely to shake is supported, and the unit roll paper 2t, 2t is detached from the connecting member 6. I get tired. Further, the roll paper 2 or the roll paper unit 2u itself is prevented from falling off from the support portions 32, 32.
In addition, since the load at the time of rotation is reduced also by becoming difficult to shake the rotating shaft at the time of rotation by such an interposition part, in this case, power saving is exhibited more effectively.

When the paper tube 21 and the connecting member 6 are supported by the interposition part 19, the part may be supported by a roller 19r as shown in FIG. Moreover, as shown in FIG.14 (C), you may comprise so that it may fit in the aspect which does not prevent rotation of the paper tube 21 and the connection member 6. FIG.
In the example shown in FIG. 14, it is easier to position the interposition part 19 at a predetermined position if the lid body 11 is a flip-up type as shown in FIG. 4 or an interposition part is provided on the back plate part.

"Attachment (exchange) mode of roll paper"
On the other hand, in the dispenser X1 of the present invention, the protruding portion 21P of the paper tube 21 protruding from each end of the roll paper 2 or the protruding portion 5P of the support shaft 5 is held by hand, and each protruding portion 21P, 5P is a pair of supporting portions. The roll paper 2 or the roll paper unit 2u can be attached to the dispenser X1 so as to be placed on the receiving portions 30, 30 of 32, 32. Accordingly, the roll paper 2 and 2u can be attached without touching the cylindrical portion 22.

In the second embodiment of the roll paper towel, the paper tube portion exposed to the separation portion 25 can be held by hand, and the support shaft 5 can be inserted. Even when the support shaft 5 is inserted, the cylindrical portion 22 is inserted into the cylindrical portion 22. Can be done without touching.
Therefore, in these forms, even if it exchanges with a wet hand, the paper towel 20 concerning the cylindrical part 22 is not wetted.

"Method for manufacturing roll paper"
Subsequently, the manufacturing method of the roll paper 2 which has the separation part 25 between the cylindrical parts 22 and 22 concerning this invention is illustrated. First, as shown in FIGS. 16A to 16D, the paper towel base paper 90 is unwound from the raw roll 9 on which the paper towel base paper 90 having a width equal to or larger than the product width of the paper towel 20 is wound.
