Description

  The present invention relates to a paper drawer / cutting apparatus for rolled toilet paper and a cantilever support structure for roll toilet paper useful for use in the paper drawer / cutting apparatus. In particular, the present invention relates to a roll-out toilet paper drawer in which roll-up toilet paper is made into a folded state suitable for manual operation of a handle or a paper unwound by a motor and is cut in an appropriate amount. -It concerns a cutting device.

  When using rolled toilet paper in the toilet, pull the roll paper held rotatably on the wall by hand, wrap it with a suitable amount using both hands, and cut it manually. It is normal to use from. Cutting the drawn paper is done by forming a cutting edge like a knife edge on the lower edge of the curved cover-like plate that partially covers the upper circumference of the roll paper, or forming a jagged edge. The cover plate is manually pressed against the roll paper to stop the rotation of the roll, and the other hand is used to tear the folded paper using the lower edge of the cover plate. For example, in a one-handed paper winder described in Japanese Patent Application Laid-Open No. 2003-106243, a paper outlet is formed through a part of a cover that covers the upper half of the roll paper, and the paper drawn out from the paper outlet is used as a winding fork. Is wound around the fork, and the wound paper is extracted from one end of the fork. Even in this case, the cutting of the paper connected to the roll paper is performed by a method in which the rewinding rotation of the roll paper is stopped by hand and the lower paper is pulled. Some toilet papers have perforated cuts at appropriate intervals in the length direction, and after pulling out the required amount of paper, hold the roll with the other hand and pull the paper. The paper is cut at the part.

As a mechanism for holding the roll paper in a rotatable manner, generally, a shaft member serving as a mandrel is loosely inserted into the center hole of the roll paper, and both ends of the shaft member are pivotally supported so as to be detachable from the side of the bracket-like machine frame. Yes. The shaft member is attached to and detached from the machine frame by providing a short shaft that is elastically displaced in the axial direction at the end of the shaft member, and inserting the short shaft portion into the recessed hole of the bracket.

  As described above, the use of conventional roll-shaped toilet paper is performed manually from paper drawer to folding and cutting, and inevitably, both hands must be used. Or it is a difficult action for people who cannot move their hands smoothly due to defects in the nervous system. In particular, in the case of cutting paper, it is necessary to fix the roll paper by hand so that the roll paper does not rotate and tear off the lower paper, and it has been impossible to cut the paper with only one hand operation.

  Also, for example, when reading a magazine in the toilet, pulling out and cutting toilet paper using both hands is a complicated operation, and it is necessary to pull out an extra amount by hand because the paper is pulled out manually. There was also a problem in saving resources.

  In spite of such daily problems, no contrivance has been taken to automatically pull out paper or automate cutting by a simple handle operation with one hand. In addition, toilet paper is a soft paper, and even though it can be torn by hand, there is a problem that it is difficult to cut easily with a cutter.

  Even in the structure in which both ends of the shaft member described above are supported on the side of the machine frame and the shaft member is inserted into the roll paper to support the roll paper, it is necessary to remove the shaft member from the machine frame for loading the roll paper. Inevitably, using both hands is essential.

  The present invention has been made in view of such circumstances, and can be performed in a series of operations from pulling out, folding and cutting roll-shaped toilet paper, and can be easily taken out in a state of being folded in a bellows shape. Therefore, the present invention provides a roll-out toilet paper drawing / cutting device which is extremely advantageous for a physically handicapped person.

A pair of opposed paper pinching members each having an inclined surface and having a paper pinching portion formed on the inner surface thereof, a paper pinching member guide that guides the paper pinching member so as to move up and down and move laterally, and the paper pinching Energize members in a direction away from each other and in a rising direction First and second spring means, and the pair of paper nipping members move and descend to press the drooping paper, and at the bottom surface of the paper nipping member, the bellows-like accumulation of the paper accumulation unit A roll-out toilet paper drawing / cutting device is provided in which paper is pressed into a folded shape and the hanging paper is pulled and cut in cooperation with the fixing operation of the roll paper by the fixing means.

  The cantilever support structure for rolled toilet paper according to the present invention has a rotatable roll paper support shaft, and a sleeve fixed to the outer periphery of the front end of the support shaft and fitted into the core tube of the roll paper, A small protrusion that extends in the axial direction and bites into the core tube of the roll paper is formed on the outer periphery of the sleeve, and the roll paper is inserted and removed from the tip of the sleeve.

  According to the present invention, in the form in which the roll paper is rewound by the driving force of the motor, the power source of the motor for pivotally supporting the roll paper for toilet is simply turned ON by, for example, a push button operation, The paper that has been rewound from the roll paper is folded over, falls to the bottom of the case, and is automatically cut in an appropriate amount so that the user can easily take out the usable paper with one hand. .

  In addition, the folding operation using both hands of the user is not required as in the past, and it can be used immediately as it is taken out. Furthermore, the amount of folding is constant and unnecessary paper withdrawal is avoided, thus saving resources. Can contribute. The cylinder placed in the case can be pushed down automatically using the driving force of the motor and a mechanism such as a rack and pinion, and this cylinder is pushed down manually. However, the operation is very simple and easy and does not require excessive force. The present invention is particularly effective for handicapped users with physical disabilities that can only be used on one hand, for example. The fixing of the roll paper required in the case of pulling and cutting the paper can be effectively realized by a brake mechanism of a motor that drives the roll paper or a mechanism of a worm and a worm gear.

  The roll paper can also be loaded so that it can be easily and securely rotated together with the support shaft by simply pushing the roll paper from one side into the tip of the roll paper support shaft. It is only necessary to pull out the core tube of the roll paper from the support shaft in the axial direction. Also, the roll paper can be easily attached with one hand of the user. Since the small ridge formed on the outer periphery of the roll paper support shaft bites into the core tube of the roll paper, the roll paper and the support shaft rotate together. Therefore, a motor is connected to the rear end of the support shaft to wind the roll paper. The return can be automatically performed. A piece of roll paper that is extremely useful when incorporated in the paper drawing / cutting device for roll-shaped toilet paper according to the present invention described above, without causing the roll paper to fall off the support shaft during use. A support structure can be provided.

  Further, according to the roll paper cantilever support structure according to one embodiment of the present invention, a roll paper support shaft that is rotatable, and a sleeve that is fixed to the outer periphery of the tip of the support shaft and that is fitted into the core tube of the roll paper. A small protrusion that extends in the axial direction and bites into the core tube of the roll paper is formed on the outer periphery of the sleeve, and the tip of the roll paper support shaft has an inner diameter of the core tube of the roll paper A plurality of slits are formed so as to be tapered with a smaller outer diameter and slightly elastically deform in the radial direction.

  Next, the present invention will be described according to the embodiments with reference to the accompanying drawings. FIG. 1 is a schematic overall plan sectional view showing a paper drawing / cutting apparatus according to a first embodiment of the present invention cut at a position of a paper sandwiching member described later. FIG. 1 is a plan sectional view taken along line AA of FIG. 6 described later. In this embodiment, the rectangular outer case 11 has a pair of paper sandwiching members 26 and a rectangular cylindrical portion 32 as movable members, and a support mechanism, guide member or compression spring means for these movable members with respect to the outer case 11. Is disposed in the vicinity of the inner wall of the outer case 11 and therefore does not interfere with the descent of the paper 20 that hangs down to the approximate center of the case. In addition, although a pair of paper clamping member 26 is opposingly arranged, let the surface which opposes be the front surface of this member 26 here, and the other side, ie, an outer part, shall be called a back surface.

  The pair of paper sandwiching members 26 arranged below the cylindrical portion 32 are each formed with an inclined surface 26a having a tapered upper end on the back surface thereof, and each paper sandwiching member as shown in FIG. A pair of guide grooves 27 penetrating in the vertical direction are formed in the lower part of the back surface near the both side portions of the back surface. As clearly shown in FIG. 4, a stepped portion 28 for receiving the first compression spring 23 is formed on the lower surface connected to the rear surface of the paper sandwiching member 26. Further, on the front surface of each paper pinching member 26 (each facing surface of the opposed paper pinching members), for example, a paper pressing member 29 such as hard rubber and a bottomed spring holding the second compression spring 22 below and on both sides thereof. A hole 30 is provided, and the pair of paper pinching members 26 are urged away from each other by the second compression spring 22 accommodated in the spring holding hole 30.

  Corresponding to the guide groove 27 of each paper pinching member 26, a plate-like paper pinching member guide 31 extending in the vertical direction is formed on the inner wall of the outer case 11. A first compression spring 23 is disposed between the bottom plate 11 b of the outer case 11 and the lower surface step portion 28 of each paper sandwiching member 26. The paper pinching member 26 is guided so as to be movable in the vertical direction and the left-right direction (direction perpendicular to the facing surface) by inserting the paper pinching member guide 31 of the outer case 11 into the guide groove 27. In this case, The pair of paper pinching members 26 are urged away from each other by the second compression springs 22 accommodated in the spring holding holes 30 and are always urged upward by the first compression springs 23 at the bottom. ing. The second compression spring 22 is selected to have a spring force weaker than that of the first compression spring 23.

  FIG. 3 is a side view of the cylindrical portion 32 according to the first embodiment of the present invention. The cylindrical portion 32 is a hollow box-shaped member having a certain rectangular thickness as a whole, and the lower ends of both opposing sides thereof are inclined to engage with the inclined surfaces 16a, 26a of the back portion of the paper sandwiching member 26. It is an end face 32a. Further, a pulling spring 68 that constantly urges the cylindrical portion 32 upward is mounted between both side portions of the cylindrical portion 32 and the inner wall 11a of the outer case 11. A cylindrical portion guide (see FIG. 1) supports the cylindrical portion 32 with respect to the outer case 11 at an appropriate position not interfering with the pulling spring 68 on the side portion of the cylindrical portion 32 and guides the vertical movement of the cylindrical portion 32. 53)) is formed. As shown in FIG. 3, a longitudinal groove 33 into which the paper pinching member guide 31 is inserted when the cylinder part 32 is lowered is formed on the side part corresponding to the lower end inclined end surface 32a of the cylinder part 32. Yes.

  The operation of this embodiment will be described with reference to FIGS. 4 to 7. FIG. 4 shows a state before use, that is, before the start of paper drawing of the paper drawing / cutting device of the toilet paper. Roll paper that is rewound and rotated by a mold motor is held (not shown in these drawings). On the bottom of the outer case 11, a pair of opposed paper restraint wall plates 65 having an appropriate height are provided. The wall plate 65 restrains the paper surface when the leading edge of the drooping paper 20 that continuously descends from above by rewinding the roll paper hits the bottom of the case and the paper surface is laterally biased. It acts to fold back into a curve, that is, a bellows. The motor is provided with an appropriate speed reduction mechanism.

  Before the start of use, the cylindrical portion 32 is separated upward from the paper pinching member 26 by a pulling spring 68, and the paper pinching member 26 is largely separated left and right by the second spring means 22 and the first spring means. 23 rises to a position close to the cylindrical portion 32. In this state, when the motor is turned on, the paper 20 from the roll paper passes through the cylindrical portion 32, passes between the pair of paper sandwiching members 26, and accumulates in a bellows shape on the bottom plate 11b of the outer case 11 as shown in FIG. To do. Here, the rotation of the motor stops, and the brake mechanism of the motor works when the power of the motor is cut off, and the rotation of the roll paper is restricted.

  Subsequently, as shown in FIG. 6, the cylindrical portion 32 is lowered against the pulling spring means 68, and the pair of paper sandwiching members 26 is a wedge between the lower end inclined end surface 32a of the tubular portion 32 and the inclined surface 26a of the back portion of the paper sandwiching member. The paper 20 is pushed inward by the action to squeeze the paper 20 between the paper pressing members 29 and pressed down toward the bottom of the outer case 11, and the bellows-like paper deposited on the bottom plate 11b as shown in FIG. The lower surface 26b of the pinching member 26 is pressed against the outer case bottom plate 11b to be in a folded state. Note that due to the relationship between the spring force of the first spring 23 and the second spring 22, the approach of the paper sandwiching member 26, that is, the paper sandwiching pressure, is slightly prior to the lowering of the paper sandwiching member 26. . At this time, the paper 20 is pulled down by the lowering of the paper pinching member 26 that pinches the paper 20, but the roll paper and the paper are prevented from being unwound by the motor with brake as described above. It is pulled and cut at a location between 20 pinched portions.

  Thereafter, when the pressing force of the cylindrical portion 32 is released, the cylindrical portion 32 is lifted by the action of the pulling spring 68, and the paper sandwiching member 26 is lifted by the first compression spring 23 and the second compression spring 22, and left and right The folding paper 35 at the bottom of the outer case can be taken out from the opening at the side of the case. The apparatus state at this time is the initial state shown in FIG.

  FIG. 8 is a partial longitudinal sectional view of Embodiment 2 of the present invention. In this embodiment, a knife-like projection 70 having a sharp tip is provided in front of the upper end of one paper-clamping member 26, and the upper part of the other paper-clamping member 26 is cut off at a position corresponding to the knife-like projection 70. Toilet paper with perforated cuts usually cuts at the perforated part due to the lowering of the paper nipping member and the tension of the paper, but in the case of paper with no cuts, it can be cut at the part of the knife-like projection 70 as described later. As a result, the paper is easily and reliably cut and pulled. There is no hindrance to the lowering of the paper when both the paper sandwiching members 26, 26 are largely separated from each other on the left and right sides. When the paper pinching member is lowered laterally by the projection 70 and the paper pinching member is lowered and the rotation of the roll paper is prevented, the tensioned paper 20 is pulled and cut at the position C of the knife-like projection 70. . In order to guide the paper that hangs down when the roll paper is rewound, the paper surface portions on both side edges of the paper are provided on both side portions 32c (FIG. 1) of the cylindrical portion 32 within a range that does not hinder the lowering of the cylindrical portion. It is also possible to form a partial paper guide 71 to guide.

  Next, a cantilever support structure for roll paper used in the present invention, that is, a structure in which roll paper for toilet paper is mounted on the output shaft of the motor will be described with reference to FIGS. 9, 10A, and 10B. . In this embodiment, the motor 55 is a small motor with a built-in brake and a reduction mechanism. When the motor 55 is turned off, the rotation of the motor 55 is stopped and fixed, and the roll paper 60 is freely rotated. It has been stopped. The motor 55 is fixedly disposed near the upper portion of the outer case 11, and a sleeve 57 having a tapered end at the tip is fitted to the output shaft 55a. FIG. 10A is an enlarged end view seen from the distal end side of the sleeve, and FIG. 10B is an enlarged side view of the sleeve. A plurality of slits 57a extending in the axial direction are formed at the tip of the sleeve 57 so as to be slightly elastically deformed in the radial direction. Further, a key groove 57b that engages with a key-shaped protrusion 55b on the outer periphery of the motor output shaft 55a is formed on the inner surface of the sleeve, and when the sleeve 57 is mounted on the motor output shaft 55a by combining the protrusion 55b and the key groove 57b, The sleeve 57 cannot rotate relative to the motor output shaft 55a and rotates integrally with the output shaft 55a. Reference numeral 58 denotes a set screw for fixing the sleeve 57 to the motor output shaft 55a. When the motor is not a motor with a built-in speed reduction mechanism, the motor output shaft is connected to the sleeve 57 via a suitable speed reduction gear mechanism.

  In this embodiment, on the outer periphery of the sleeve 57, there are formed sharp ridges 59 extending in the axial direction and having a small height. The ridges 59 are formed on the outer periphery of the sleeve 57, or two or three at most. When the sleeve 57 is inserted so as to be pushed into the center hole of the roll paper 60, the ridge 59 is a paper core of the roll paper 60. The roll paper 60 bites into the inner periphery of the tube 61 and thereby the roll paper 60 rotates integrally with the sleeve 57, thereby preventing the roll paper 60 from sliding on the sleeve 57.

  Prior to mounting the sleeve 57 on the motor output shaft 55a, the spacer 56 having a diameter larger than the outer diameter of the sleeve 57 is inserted into the motor output shaft 55a so as to contact the front end of the motor main body, and thereafter the sleeve is inserted. 57 is inserted to a position where it contacts the end face of the spacer 56. That is, the spacer 56 is sandwiched between the front end of the motor body and the sleeve end surface. The roll paper 60 is attached to the sleeve 57 so as to be pushed from the front end of the sleeve 57, and the back end surface 60a of the roll paper 60 is brought into contact with the end face of the spacer 56, whereby the roll paper 60 is positioned with respect to the motor 55. Is made. The protrusions 59 of the sleeve 57 are for preventing slippage in the rotational direction between the roll paper 60 and the sleeve 57, and have a very small shape so as not to impair the ease of insertion of the roll paper 60. Is selected. When the roll paper 60 has been used up, the core tube 61 at the center of the roll is removed from the sleeve 57 and a new roll paper is loaded.

  The above-mentioned form of engagement between the motor and the roll paper is an example, and any other structure can be adopted as long as the roll paper rotates integrally with the motor output shaft without idling. It is. Further, as a structure for preventing the rotation of the roll paper when the motor is stopped, a meshing structure of a worm and a worm gear which is so-called automatic tightening can be adopted. Fit the shaft of the worm gear with shaft into the center hole of the roll paper so that it cannot rotate relative to it, connect the worm to the motor output shaft integrally, and transmit the rotation of the motor to the roll paper with this worm and worm gear transmission mechanism It may be. With this structure, rotation transmission from the roll paper side to the motor output shaft becomes impossible, and rotation of only the roll paper becomes impossible when the motor stops. Therefore, in this case, the motor does not have to be equipped with a brake.

  FIG. 12 is a longitudinal sectional view showing a third embodiment in which a mechanism of a worm and a worm gear (worm wheel) is used as the roll paper fixing means according to the present invention. A middle portion of the roll paper support shaft 72 is rotatably supported by the outer case 11 via a pair of bearings 73 and 74. One end of the roll paper support shaft 72 is inserted into the sleeve 57 described in FIG. 9 and is key-connected, and a worm gear 75 is fixed to the other end of the support shaft 72. 76 is a cylindrical spacer interposed between one bearing 73 and the worm gear 75, and the worm gear 75 is pressed against the spacer 76 by a fastening nut 77 screwed to the shaft end of the support shaft 72. Secured to the shaft 72.

  A spacer 78 is interposed between the sleeve 57 and the other bearing 74. The roll paper 60 is attached to the sleeve 57 so as to be pushed in from the front end of the sleeve 57, and the positioning of the roll paper 60 is performed by contacting the back end surface 60a of the roll paper 60 with the spacer 78 as described in FIG. Is made. The sleeve 57 has a tapered shape with a tapered tip, and a plurality of small slits 57a are formed so as to be slightly elastically deformed in the radial direction. 58 is a set screw for fixing the sleeve 57 to the roll paper support shaft 72, and 57b is a keyway formed on the inner periphery of the sleeve. On the outer periphery of the sleeve 57, a ridge 59 that bites into the core tube 61 of the roll paper 60 is formed.

  A roll paper rotation motor 55 is attached to the outer case 11, and a worm 79 that meshes with the worm gear 75 is fixed to an output shaft thereof. In this case, the worm gear mechanism transmits the rotational power from the worm 79 as the driving vehicle to the worm gear 75 of the driven vehicle, but the reverse, that is, the worm gear 75 cannot rotate the worm 79 so-called automatic tightening. ing. Therefore, when the rotation of the motor 55 is stopped, the roll paper 60 is not rotated by the pulling of the paper drawn from the roll paper 60, and the paper is pulled and cut between the roll paper 60 and the paper pressing member 29 (FIG. 7). Is done. A motor 55 with a built-in speed reduction mechanism is used. When the speed reduction mechanism is not built in, the motor output shaft is connected to the worm 79 through an appropriate gear speed reduction mechanism.

  In any of the above embodiments, the roll paper is rewound and rotated by the power of the motor. However, the roll paper may be manually rotated without using the motor. FIG. 13 is a cross-sectional view illustrating an example in which roll paper is rotated through a transmission mechanism of a worm and a worm gear by manual operation of the handle as Example 4. In this figure, the same parts as those in FIG. 12 are denoted by the same reference numerals, and redundant description of those parts is omitted as much as possible. A cantilever support structure similar to that described with reference to FIGS. 9 and 12 is used as a mechanism for rotatably supporting the roll paper 60. A worm gear 75 is fixed to the outer end portion of the roll paper support shaft 72 that is pivotally supported by the outer case 11, and a worm 79 that meshes with the worm gear 75 rotates to a pair of brackets 80 extending laterally from the outer case 11. It is pivotally supported. The shaft end 79 a of the worm 79 is fixed to the handle 81 at the position of one bracket 80, and an operation knob 82 that is rotatable with respect to the handle 81 is pivotally supported at the tip of the handle 81.

  By grasping the operation knob 82 with one hand and rotating the handle 81 in the roll paper rewind direction, the worm 79 rotates, the roll paper 60 is rewound via the worm gear 75 and the support shaft 72, and the drooping paper is a pair. Descends between the paper sandwiching members 26 (FIG. 4). Also in the fourth embodiment, the rotation operation is not transmitted from the roll paper 60 side to the handle 81 side, and the rewinding rotation of the roll paper 60 is fixed only by releasing the handle 81. The folding amount of the accordion-shaped paper, that is, the rotational speed of the handle 81 may be arbitrary depending on the user, but a mechanism for detecting the rotational speed of the roll paper 60 is added as a guide for the amount of paper used at one time. When the predetermined number of rotations is reached, it is possible to instruct the rotation operation of the handle 81 to be stopped, for example, by turning on a lamp.

  Both manual and automatic means can be adopted as the mechanism for moving the cylinder portion up and down. When adopting a mechanism that lowers the cylinder part by manual operation, a groove extending in the vertical direction is provided through the side surface of the outer case, and a knob that protrudes outside the outer case through this groove is provided on the side part of the cylinder part. After mounting and rotation of the motor stops, the cylinder is lowered by pushing down the knob by hand, and when the knob is released, the cylinder is pulled by the spring force of the pulling spring mounted between the cylinder and the outer case. Configure to rise. Of course, an appropriate guide for guiding the cylindrical portion in the vertical direction is provided on the inner side surface of the outer case.

  The amount of paper that is folded depends on the amount of rotation of the roll paper rewinding motor. Therefore, the rotational speed of the motor is set in advance so as to obtain an appropriate folding amount, and an electric circuit is automatically added so that the motor is automatically turned off when the rotational speed is reached. It is also possible for the user to select a large or small two-stage selection of the folding amount of the paper, for example, by operating a push button or the like.

  When adding an automatic pressing mechanism for the cylindrical portion, a small motor 50 different from the roll paper rewinding motor is mounted on the outer case 11 as illustrated in FIG. A vertically extending rack 51 that is exposed to the outside of the outer case 11 is fixed. A pinion gear 52 that meshes with the rack 51 is connected to the output shaft of the cylinder part vertical movement motor 50, and the cylinder part 32 is connected via the engagement between the rack 51 and the pinion gear 52 when the motor 50 is turned on. Configured to descend. In this case, the power source of the cylinder part vertical movement motor 50 is the same as that of the roll paper rewinding motor, and the cylinder part is automatically turned on with a delay of a predetermined time just by turning on the power of the roll paper rewinding motor. It is preferable to add an electric circuit so that the power of the vertical movement motor 50 is turned on. The user only needs to operate one power switch, and thereafter, the user only has to take out the folded paper from the take-out port formed in the lower part of the outer case.

  In FIG. 1, reference numeral 53 denotes a guide that supports the cylindrical portion 32 with respect to the outer case 11 and guides its vertical movement. When the power for lowering the tube portion is insufficient, two motors of the same type may be provided on both sides of the outer case 11 to increase the power.

  11A is a partial enlarged plan sectional view taken along line BB in FIG. 7, and FIG. 11B is an enlarged side view taken along line BB in FIG. On the inner surface of the paper constraining wall plate 65, a plurality of uneven portions extending vertically are formed. Similarly, a plurality of concave and convex portions are formed on the side surface of the paper sandwiching member 26 facing the wall plate 65, and the convex portion 66 of the member 26 enters the concave portion 67 of the wall plate 65 as shown in the figure. Yes. Each convex portion 66 of the paper sandwiching member 26 has a width wider than each concave portion of the member. The bellows-like paper 20 (shown in phantom lines in FIG. 11) that is constrained in the lateral direction by the convex portions 68 of the wall plate 65 is pressed against the case bottom plate by the lower surface of the convex portions 66 of the paper sandwiching member 26. As a result, the paper 20 is effectively folded. With this configuration, even if there is a slight gap between the side portion of the paper sandwiching member and the wall plate 65, folding of the paper is effective.
