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.
This type of dispenser is usually configured such that one continuous paper towel fed out from one roll is discharged from a discharge outlet. That is, only one characteristic paper towel can be used.
However, users usually want to wipe off a lot of moisture first, then finish with a comfortable paper towel, or after wiping their hands with a paper towel containing chemicals such as disinfectant and softener, There are cases where it is desired to use different types of paper towels in one wiping operation, such as wiping with a paper towel. This means that it is desired to use a paper towel having different characteristics and quality in one wiping. However, the conventional dispenser described above cannot cope with this.
Here, as paper towels, so-called two-plies and three-plies are known, and paper towels with different paper qualities and characteristics are also known for each constituent ply.
However, in such a pre-ply structure, for example, even if the user wants to use an A-roll paper product with excellent moisture absorption and a B-roll paper product with good touch, It cannot be used selectively.
On the other hand, in order to solve the problem of wiping with different types of paper towels, it may be possible to install multiple dispensers. It is often installed in a relatively small place, and there are cases where a plurality of dispensers cannot be installed from the viewpoint of the installation place.

"Outline of roll paper towel dispenser"
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. A dispenser (hereinafter also simply referred to as a dispenser).

  And this dispenser X1 of this form is the characteristic roll paper towel unit 2u of the structure where the cylindrical part 22 which wound the strip | belt-shaped continuous paper towel 20 is lined up coaxially so that a rotating shaft may be shared, or reference form. Used for roll paper towel 2.

  The dispenser X1 of this embodiment includes a housing 1 for housing each mechanism and roll paper towel unit whose material is a synthetic resin such as ABS resin, or a metal material, and this roll paper towel unit 2u (hereinafter simply referred to as “roll paper towel unit”). A roll paper unit 2u) or a roll paper towel 2 (hereinafter also simply referred to as roll paper 2) as an example of the reference embodiment, and a support portion 3 for pivotally supporting the roll paper towel 2 and the cylindrical portions 22 and 22 The first guide member 4 that guides the transport direction of each of the continuous paper towels 20 and 20 that are taken out in a direction that intersects with each other, and each continuous paper towel 20 and 20 that is transported in the direction that intersects with the first guide member 4. Are changed to the same transport direction, and the continuous paper towels 20 and 20 are ; And a second guide member 5 for guiding to fit Ri.

  Further, the second guide member 5 is rotated in a state in which the free front end portions 20t and 20t of the continuous paper towels 20 and 20 having the same transport direction and overlapping are nipped, and the free end portions 20t and 20t are stacked. A sheet discharge roller 6 that discharges the sheet in a state, and a sheet discharge port 60 that exposes the free stacking end portions 20t and 20t fed out by the rotation of the sheet discharge roller 6 to the outside of the housing.

  Here, in the present embodiment, as a preferred embodiment, the length is automatically discharged appropriately by driving the discharge roller 6 that nips the paper towel unwound from the roll paper unit or the like according to the sensor. Has been. Note that a publicly known configuration can be used as a mechanism and configuration for discharging paper according to the sensor, and the present invention is not limited thereto. A mechanism / configuration for discharging paper in accordance with the sensor is disclosed in, for example, Japanese Translation of PCT International Application No. 2008-521549.

  Since the dispenser X1 of the present invention uses the roll paper 2 or the roll paper unit 2u described above, a plurality of continuous paper towels 20 and 20 are stacked from the paper discharge port 60 even in a single dispenser X1. Can be discharged. In particular, different types of continuous paper towels 20, 20 constituting each cylindrical portion 22, 22, for example, lotion-coated paper towels or non-lotion-coated paper towels, and different types of paper towels are discharged at once in a laminated state. You will be able to paper.

  In addition, since the two continuous paper towels 20 and 20 can be discharged by one dispenser, it is excellent in compactness as compared with the case where two dispensers are provided. In particular, the dispenser X1 of the present invention uses the roll paper units 2 and 2u in which the cylindrical portions 22 and 22 are aligned with each other in the rotational axis direction at the end face, so that the two cylindrical portions 22 and 22 are accommodated. Regardless, the depth of the dispenser can be similar to that which accommodates a single cylindrical portion and there is no increase in ledge when attached to the wall.

Hereinafter, each part, each mechanism, etc. of the dispenser X1 of this invention are explained in full detail.
First, the characteristic roll paper unit 2u of this invention and the roll paper towel 2 of a reference form example are demonstrated in order of the roll paper of a reference form, and the roll paper unit which concerns on this embodiment.
In order not to disturb the compactness of the dispenser X1, the total length of the roll paper 2 or the roll paper unit 2u, that is, the distance between both ends in the axial center is preferably 333 to 710 mm.

“First example of roll paper towel as a reference form”
In the first embodiment of the roll paper towel 2 of the reference form, as shown in FIG. 7 in particular, two long and continuous belt-like paper towels 20 and 20 are wound between both ends of one paper tube 21. Yes. Therefore, the cylindrical portions 22 and 22 formed by winding the continuous paper towels 20 and 20 share one paper tube 21. Further, both end portions 21 </ b> P of the paper tube 21 protrude from the cylindrical portion 22 and are exposed.

  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 cylindrical portion in a roll paper towel having one known general cylindrical portion (the second embodiment described below). The same applies to the embodiment of the roll paper unit). 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 the required length. On the other hand, if it exceeds 250 mm, it is difficult to make the dispenser X1 compact, and the weight increases and the burden on the support 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, in the roll paper 2 according to the present embodiment, since both end portions 21P and 21P of the paper tube 21 protrude from the end face of the cylindrical portion 22, the compactness of the dispenser X1 is extremely deteriorated when the width exemplified above is exceeded. .

  Here, the distance L2 between the adjacent cylindrical portions 22 and 22 is desirably 3 to 20 mm from the viewpoint of compactness of the dispenser X1 and preventing the continuous paper towels from being entangled.

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 formed by winding a long paper tube base paper (the same applies to the embodiments of the roll paper unit described below). The basis weight of 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.

Here, the protrusion length L5 of the both ends of the paper tube 21 in this embodiment is not particularly limited. It is good to set it as about 10 to 15% of the width | variety of the one cylindrical part 22. FIG. As a concrete numerical value, it is good to set it as 15-45 mm. If it is this range, it can be set as the paper width of the grade suitable for a use surface, without deteriorating the compactness of dispenser X1.
In addition, although 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, it is as follows about a preferable example.

  The paper towel which is a constituent material of the roll paper of this embodiment can be manufactured using only virgin pulp, waste paper pulp, or a mixture thereof as a paper material. 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.

Although the basis weight of the paper towel can be 15~65g / m ² about, 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, it is preferable that the specific value of the wet tensile strength (JIS P 8135 1998) of the paper towel is 500 to 1500 cN / 25 mm in the longitudinal 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 conventionally well-known thing can be suitably employ | adopted in the range which does not inhibit the effect of this invention.

“Second example of roll paper towel as a reference form”
As shown in FIG. 8, the second embodiment of the roll paper towel 2 of the reference form is similar to the first embodiment described above. Two long and belt-like continuous paper towels 20 and 20 are formed in one paper tube. Are wound next to each other. Further, cylindrical portions 22 and 22 formed by winding the paper towels 20 and 20 share one paper tube 21. 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. Other configurations such as the configuration of the paper tube 21 and the cylindrical portion 22 are the same as those in the first embodiment.

"Example of roll paper towel unit"
In the embodiment of the roll paper towel unit 2u according to the embodiment of the present invention, as shown in FIG. 9, in particular, one long and strip-shaped paper towel 20 is wound around one paper tube 21, and the continuous paper towel 20 is wound. A roll paper 2t having a general structure in which both ends of the cylindrical portion 22 as a part and both ends of the paper tube 21 coincide with each other is connected coaxially through a connecting member 25. It is formed by connecting them individually. The paper towel 20 is the same as in the first embodiment.

  As shown in FIG. 10 in particular, the connecting member 25 has both ends 25A, 25A in the form of a coaxial cylinder, and at least both ends 25A, 25A have the same or slightly smaller diameter than the inner diameter of the paper tube 21. . By inserting both end portions 25A and 25A of the connecting member 25 into the paper tubes 21 of different unit roll papers 2t and 2t, the unit roll paper towels 2t and 2t are connected coaxially.

  The outer diameters of both end portions 25A and 25A may be designed to be different depending on the unit roll papers 2t and 2t having different paper tube inner diameters.

  Here, it is desirable that the outer diameters of both end portions 25A and 25A inserted into the paper tube 21 of the connecting member 25 and the inner diameter of the paper tube 21 are completely coincident with each other. If the outer diameter of the portion 25A 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 length of both ends 25A to be inserted is 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, 10-15% of the width is the same), and 15-45 mm is desirable for specific numerical values.

On the other hand, the connecting member 25 according to the present embodiment includes stopper portions 25B and 25B provided so as to protrude to the outer surface between both end portions 25A and 25A inserted into the paper tube 21 of the unit roll paper 2t. Yes. The stopper portions 25B and 25B prevent the unit roll papers 2t and 2t from moving in the contact direction, and prevents the end portion 25A from being excessively inserted into the paper tube 21. In the illustrated form, the unit roll papers 2t and 2t are separated from each other so that the unit roll papers 2t and 2t are separated from each other, but two stopper portions 25B and 25B are formed. There may be.
The stopper portion 25B is preferably disk-shaped as shown in the example from the viewpoint of preventing over-insertion and preventing shaking during rotation of the roll paper unit 2u.

  When two unit roll papers are connected using the connecting member 25 as described above, the unit roll paper 2t is not only one having a paper tube, but instead of a paper tube, A so-called coreless unit roll paper having an air core portion hardened with water-decomposable glue can be used. In that case, the end portion 25A of the connecting member 25 may be inserted into the air core portion.

“Example of housing structure”
Next, structural examples of the housing will be described. As shown in FIGS. 1 to 5, the housing 1 is composed of a case body 10 that is open on the front surface and a lid body 11 that covers a front surface opening portion of the case body 10. The paper discharge port 60 exposes the continuous paper towels 20 and 20 unwound from the roll paper unit 2u supported by the roll paper 2 or the roll paper 2 of the reference form to the outside of the housing.

  The case main body 10 includes a top plate portion 12, a bottom plate portion 13, a back plate portion 14, and a pair of left and right main body side plate portions 15 and 15 extending forward from both side edges or both side edges of the back plate portion 14. It is installed on the wall surface or the like via the back plate part 14.

  The lid 11 has a front plate portion 16 having a curved surface portion whose upper part is in a series with the top plate portion 12 of the case body 10, and is formed on the back side (back plate side) at right angles to the front plate portion 16. It has a pair of left and right lid side plates 17, 17 that extend, and is arranged so as to cover the front side open portion of the case body 10, and constitutes a box-shaped housing 1 together with the case body 10.

Further, as shown in FIG. 3, the lid 11 is attached to the case body 10 in a hatched manner, and by pulling down, the case body 10 is opened to the front, the support mechanism inside the housing, the discharge roller 6 and the like. The internal mechanism is exposed, and the roll paper 2 or the roll paper unit 2u can be replaced.
In making such a hatch type, the hinge mechanism 18 may be provided on the front side edge of the bottom plate portion 13 of the case body 10 and the lower edge of the front plate portion 16 of the lid body 11.
In addition, as shown in FIG. 4, the hinge mechanism 18 is provided in the front side edge of the top-plate part 12 of the case main body 10, and the back side upper edge of the front board part 16 of the cover body 11, and it is made to flip up the front surface. It may be an expression.

  Furthermore, a pair of locking projections (not shown) are provided at the upper or lower portion of each main body side plate, and a pair of locking fitting holes corresponding to the locking projections at the upper or lower portion of each lid side plate. (Not shown) may be provided, and the case main body 10 and the lid body 11 may be coupled by fitting them. 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 60 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 paper discharge port 60 is formed so that the user can easily take out the paper towel.

  Further, in the illustrated example, as shown in FIG. 5 in particular, the cutter blade 60c is partially applied to the paper discharge port 60 in order to facilitate the cutting of the continuous paper towels 20 and 20 exposed from the paper discharge port 60. Installed. In the illustrated example, the cutter blade 60c is a saw blade. The cutter blade 60c can be formed of metal or a hard plastic resin.

“Example of support mechanism for roll paper”
Next, an example of a support mechanism such as roll paper will be described with reference to FIGS. The dispenser X1 of the present invention is configured so that the roll paper units 2u, 2 are supported by a pair of support portions 3, 3. The support portions 3, 3 include a pair of arm portions 31, 31 extending from the vicinity of both side plates of the back plate portion 14 toward the front plate side (the front side when the wall surface is attached), respectively, and arms thereof. Standing in parallel toward the upper side (top plate side) on the back plate side and the front plate side in a state where the lid is closed and parallel to the back plate portion at the distal ends of the portions 31 and 31, respectively. A pair of convex pieces 33 and 33 and a receiving surface 34 positioned between the convex pieces 33 and 33. The receiving surfaces 34, 34 of the support portions 3, 3 are configured such that the bottom height position is the same position. The dispenser X1 is installed so that the line connecting the bottoms of the receiving surfaces of the support portions is horizontal.

  In the support portions 3 and 3, in the first embodiment of the roll paper, the roll paper 2 is placed on the paper tube 21 by placing the protruding portions 21 </ b> P and 21 </ b> P of the paper tube on the receiving surface 34. The protrusions 21P and 21P that protrude and are exposed are supported so as to be rotatable.

  On the other hand, if the second embodiment of the roll paper and the embodiment of the roll paper unit 2u are supported, for example, the length of the paper tube in the second embodiment, the embodiment of the roll paper unit 2u. A cylindrical or columnar support shaft 28 that is longer than the length (width) of the roll paper unit 2u is inserted into a paper tube or the like, and the portions 28P and 28P exposed from the paper tube or the like are used as receiving surfaces. By mounting, the second embodiment of the roll paper or the roll paper unit 2u can be rotatably supported.

  In the case of supporting in this way, the protruding length L5 of both end portions 21P of the paper tube 21 and the length L6 of the protruding portion 28P of the support shaft 28 in the first embodiment of the roll paper are the width of one cylindrical portion 22. It is good to set it as about 10 to 15%. As a concrete numerical value, it is good to set it as 15-45 mm. Within such a range, the roll papers 2 and 2u can be sufficiently supported, and the paper width of the width suitable for the use surface can be obtained without deteriorating the compactness of the dispenser X1.

  When the support shaft 28 is inserted into the paper tube 21 and the continuous paper towels 20, 20 wound around the paper tube 21 are pulled out, there is a margin between the support shaft 28 and the paper tube 21. In this case, roll paper or the like flutters. Therefore, considering this point, it is desirable that the outer diameter of the support shaft 28 is close to the inner diameter of the paper tube 21. Specifically, it is desirable to be within 1 mm.

  Furthermore, the material of the support shaft 28 is formed of a hard material that does not easily bend or bend, and specific examples include metals and hard plastic materials.

  Here, the support portions 3 and 3 in the dispenser X1 of the present invention are not limited to the illustrated example, and the arm portions 31 and 31 may extend from the side plate portion 15 so as to protrude in the horizontal direction. In addition, it may be an aspect that hangs down from the top plate portion 12 or may stand up from the bottom plate portion 13 toward the top plate portion 12. If the arm part 31 positions the support part 3 in a predetermined position in the range which does not prevent the effect of this invention, the specific aspect will not be limited.

  Further, the support portions 3 and 3 have a smooth circular arc surface 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 through the receiving surface 34. Alternatively, it is desirable that the curved surface is a semi-cylindrical surface, and the paper tube 21 or the support shaft 28 is smoothly rotated. Furthermore, 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 28 so that the paper tube 21 or the support shaft 28 can rotate between the convex pieces. It is desirable to fit in the state. In this way, when the roll paper 2 and the roll paper unit 2u are rotated, the paper tube 21 or the support shaft 28 does not flutter between the convex pieces 33, 33, and the paper towel is reversed in the direction opposite to the paper discharge direction when fluttering. Thus, an unnecessary load is not applied to the paper discharge roller 6. For example, unnecessary power is not consumed when the paper discharge roller 6 is driven by electric power.

  As the other support portion, as shown in FIG. 14 in particular, one provided with convex portions 135 and 135 protruding in the center in the width direction of the housing at the tips of the arm portions 31 and 31 can be exemplified. The support portions 3 and 3 loosely fit the convex portions 135 and 135 to the opening portions at both ends of the paper tube 21 of the roll paper towel unit 2u and 2 and support the roll paper unit 2u and 2 so as to be rotatable. .

"First guide member"
Next, the first guide member 4 according to the present invention will be described. The first guide member 4 of this embodiment is shown in FIGS. 15 to 17 in particular. The first guide member is formed from the cylindrical portions 22 and 22 of the roll paper unit 2u and 2 supported by the support portion 3. It is located in the conveyance path | route of each continuous paper towel 20 and 20 unwound toward the rotation direction, and changes the conveyance direction of each continuous paper towel so that the conveyance direction of each continuous paper towel 20 and 20 may mutually cross | intersect. .

  As a specific example, as in the examples shown in FIGS. 15 and 16, an abacus ball-shaped member having a pair of truncated cone parts 41 and 41 having the same diameter increasing from both ends 4t and 4t toward the center 4c. Can be illustrated. A preferred frustoconical part is a regular frustoconical part.

  The first guide member 4 of this form is arranged so that the central axis A2 of the truncated cone portions 41, 41 is parallel to the rotation axis A1 of the roll paper. Moreover, each truncated cone part 41 and 41 becomes a position corresponding to each continuous paper towel 20 and 20 wound out toward the tangential direction of the end surface from the cylindrical parts 22 and 22 of the roll paper units 2u and 2 respectively. Are arranged as follows.

  In the first guide member 4 having such a configuration, the continuous paper towels 20 and 20 unwound from the cylindrical portions 22 and 22 are respectively wound around the conical surfaces 41P and 41P of the truncated cone portions 41 and 41, respectively. The conveyance direction of each continuous paper towel 20 and 20 is changed so that it may go to the center of the width direction, and it guides so that the conveyance direction of each continuous paper towel 20 and 20 may cross | intersect. Here, the change in the transport direction will be described more specifically. The crossing angle between the central axis A2 of the truncated cone portion 41 of the first guide member 4 and the line C1 passing through the conical surface and intersecting the axis. Is changed so that the conveyance direction is biased toward the center by the angle θ.

  Here, since the distance until each continuous paper towel intersects is determined by this angle θ, if this angle θ is gentle, the distance until each continuous paper towel intersects becomes longer, and each continuous paper towel is stacked. It takes a long distance to make the dispenser compact. On the other hand, if it is steep, the continuous paper towel tends to be displaced from the truncated cone surface. Considering these points, it is desirable that the angle θ is 14 to 56 degrees, preferably 30 to 45 degrees.

  Note that the first guide member 4 may be rotatable about the central axis A2 as a rotation axis, or may be non-rotatable. The material constituting the conical surface 41P is preferably a rubber material so that the conical surface 41P and the continuous paper towel 20 do not slip. If non-rotating, the conical surface 41P can be made of a metal material, and the continuous paper towel 20 can be slid and guided as a smooth surface.

  In the illustrated example, the first guide member 4 is disposed below the support position of the roll paper units 2u, 2 and unwinds downward from the roll paper units 2u, 2. Each of the continuous paper towels 20 and 20 is wound around the conical surfaces 41P and 41P of the truncated cone portions 41 and 41 of the first guide member 4, and then the conveying direction is turned upward, and the continuous paper towel is used. 20 and 20 are comprised so that a conveyance direction may change to the direction which mutually cross | intersects. However, the position of the first guide member 4 is not necessarily limited to this position.

  The first guide member 4 illustrated above is an integral member that shares a pair of truncated cone portions 41, 41, but the truncated cone portion around which each continuous paper towel 20, 20 is wound is a separate body. May be. In this case, the center axis of each truncated cone part may be arranged parallel to the rotation axis of the roll paper. Further, the present invention is not limited to a member having a truncated cone portion, and a pair of separate guide rollers and guide bars can be configured by arranging the central axis thereof at an appropriate angle with respect to the rotation axis of the roll paper.

"Second guide member"
Next, the second guide member 5 according to the present invention will be described. The second guide member 4 of this embodiment is particularly shown in FIGS. 15, 18, and 19. The second guide member 5 changes the transport direction of the continuous paper towels 20 and 20 transported in the direction intersecting by the first guide member 4 so as to be the same transport direction, and each continuous paper towel 20 , 20 are guided so as to overlap each other.

  As a specific example, it is constituted by a pair of guide rolls 50, 50 having a cross-sectional diameter, and each guide roll 50, 50 is in a position shifted in the depth direction (between the front plate side and the back plate side), A surface in the depth direction in which the central axes A3 and A3 are non-parallel and pass through the rotation axis A1 of the roll paper 2 or 2u (usually this is because the rotation axis of the roll paper is installed horizontally) The surface is a horizontal plane) and is arranged so as to intersect at the same angle.

If the angle with respect to the surface in the depth direction passing through the rotation axis A1 of the roll paper in the guide rolls 50, 50 constituting the second guide member 5 is an angle −θ, the second guide member 5 is attached by the first guide member 4. The angle θ is corrected so as to return the conveying direction to the tangential direction with respect to the end faces of the cylindrical portions 22 and 22 (in FIG. 18, a plane parallel to the plane passing through A1 is indicated by reference numeral A1 ′). .
Note that the specific distance between the second guide member and the first guide member is appropriately designed according to the angle θ, the width of the cylindrical portion, that is, the width of the paper towel, how much region is overlapped, and the like. .

  Here, each of the guide rolls 50, 50 may be configured to rotate or may be configured to be non-rotating. If rotating, it is desirable to form the peripheral surface with a rubber material or the like so that the continuous paper towels 20 and 20 do not slip. If non-rotating, the continuous paper towels 20 and 20 may be in sliding contact with the peripheral surface as a smooth surface.

  In the illustrated embodiment, the second guide member 5 is positioned forward (front plate side) above the support position of the roll paper units 2u, 2 and above the first guide member 4. The continuous paper towels 20, 20 wound around the first guide member 4 and conveyed upward are wound around the front plate portion side 16 from the back plate portion side 14, and again the lower discharge port 60. It is configured to head toward.

"Eject mechanism"
On the other hand, the discharge mechanism of the dispenser X1 of the present invention can be understood from FIGS. 5, 6 and 20 in particular. The dispenser X1 of the present invention has a paper discharge roller 6 below the support portions 3 and 3 (on the bottom plate side). An example of the paper discharge roller 6 is a rod-shaped rotation shaft having an axis parallel to the axis (rotation axis) when the roll paper 2 or the roll paper unit 2 u is supported and attached by the support portions 3 and 3. 61, and a rubber roll portion 62 provided at an appropriate position on the outer periphery thereof. And it unwinds from each cylindrical part 22 and 22 of the said roll paper 2 or the roll paper unit 2u with the nip means 63 used as a pair, and it is the front-back direction in the front view by the 1st guide member 4 and the 2nd guide member 5. The continuous paper towels 20 and 20 that are overlapped at the same position are sandwiched simultaneously. Thereby, each continuous paper towel 20 and 20 is made into a lamination | stacking state.
In this stacked state, the paper discharge roller 6 is rotated, so that the continuous paper towels 20 and 20 are discharged from the paper discharge port in the stacked state.

  In the drawing, both end support portions of the paper discharge roller 6 and the nip roller 63 are not shown. A well-known support mechanism can be adopted for the both end support portions. The nip means 63 is attached to the front plate portion 16 or the like of the housing 1 so as to press the continuous paper towels 20 and 20 against the paper discharge nip 6 or a rubber nip roll paired with the rubber roll portion 62. A pressing means such as a pressing spring can be exemplified (this form is not shown).

  Here, in the dispenser X1 of the present invention, the rotating shaft 61 is rotated by a driving source 70 that is driven by power supply from a power source 75 such as a known motor means, so that the paper discharge roller 6 is driven by electric 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 61 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 free tips 20t and 20t of the laminated continuous paper towels 20 and 20 are exposed from the paper discharge port 60 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 this way, when the paper discharge roller 6 is driven by electric power and the stacked continuous paper towels 20 and 20 are automatically discharged, the paper can be reliably discharged in a stacked state. The possibility of pulling out only one sheet is prevented.

"Other"
In the dispenser of the present invention, a guide roll and a nip roll for guiding the continuous paper towel can be appropriately disposed in the casing within a range not impeding the effects of the present invention.

  In the dispenser of the present invention, the continuous paper towel unwound from each cylindrical portion 22, 22 is skipped as it is, that is, without being wound around the first guide member 4 and the second guide member 5. If the paper is nipped by the paper roller and the nip means and discharged, the paper can be discharged from the paper discharge port in parallel without stacking a plurality of continuous paper towels. In this case, if each continuous paper towel is of a different type, different vapors are discharged separately without being stacked. Here, when the non-laminated paper discharge of the continuous paper towels 20 and 20 is performed in this way, the continuous paper towels 20 and 20 are unwound from the state where the paper towels are supported on the support portions 3 and 3, and directly When the first guide member 4 and the second guide member 5 exist in the path sandwiched between the paper discharge roller and the nip means, an appropriate guide roller is provided so as to circumvent these to constitute a paper run. do it.

  When the first guide member 4 and the second guide member 5 are skipped, the dispenser of the present invention can use a paper towel having only one cylindrical portion as long as it can be supported by the support shaft 3. . Of course, it is possible to use a roll paper having one cylindrical portion even if only one truncated cone portion of the first guide member 4 and one guide roll of the second guide member 5 corresponding thereto are used. is there.

Here, in the illustrated example, the width of the paper discharge port is substantially the same as the width of the dispenser. However, if only the stacked paper discharge is to be performed, the width should be an appropriate width according to the width of the stacked continuous paper towel. Can do.
