Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the configuration of a roll paper holder,
In particular, there is a reserve roll paper storage section on the upper side of the container.
The roll paper drawers are connected to each other on the lower side, and by releasing the holding of the spare roll paper, the paper core remaining in the paper drawer part is automatically discharged, and the spare roll paper is pulled out. It is designed to guide people to the department.

Roll paper holders, which have been commonly used in restrooms and the like, generally support the roll paper core in the lateral direction and pull out the paper. Further, these roll paper holders are generally provided with a shaft that supports the core, and are often capable of supporting only a single roll paper (hereinafter simply referred to as a roll). Therefore, it was necessary to provide a special stand for arranging the spare rolls. There are also holders that have a pedestal and storage area for placing spare rolls, but when replacing a roll, first remove the supporting shaft and remove the remaining core, then take a new roll and attach the shaft to the core. It is necessary to insert it and place it in the holder.
Therefore, it is difficult to work with one hand, and it is troublesome to attach and detach the outer support shaft, which requires both hands. Furthermore, when setting up a new roll, there is a direction in which the sheet paper is pulled out, that is, a direction in which the roll is rewound and rotated.
If you do this incorrectly, it may be difficult to pull out or the cutting device may not work. On the other hand, a vertical two-stage roll holder is also known in which a spare roll is stored and held at the top of the roll that is being used, i.e., being pulled out. No countermeasures have been taken, and as with the stand-alone type, the winding core must be removed or discarded using both hands, which is time-consuming. Furthermore, in such a multistage holder in which the direction of paper withdrawal is determined, it is difficult to change the direction of the preliminary storage roll, and special care must be taken when loading the preliminary roll. This is a holder that can place a spare roll on top of the roll being pulled out, and when the roll is pulled out, the spare roll can be moved to the pulled-out roll position with a simple one-handed operation, and the remaining core is automatically ejected. A roll paper holder that does this is desired.

The present invention has been made with attention to these points, and a spare roll storage section is provided on the upper side of the roll paper holder to accommodate and hold the spare rolls. It is constructed so that the hold on the spare roll is released and lowered into the drawer section, and the used core can be automatically discharged, and the roll is also constructed so that it can rotate in any direction and draw out the paper. . The present invention will be described in detail below based on the drawings, but the drawings show an example of a specific implementation of the present invention, and the present invention is not limited to the illustrated example. It is also possible to carry out the same implementation by changing , or by changing a part of the shape.

FIG. 1 is a front view of a roll paper holder according to the present invention, FIG. 2 is a left side view of FIG. 1, and FIG. 3 is a partially cutaway plan view of FIG. 2.
4 is a sectional view in the direction of the arrow along the cutting line - in FIG. 2, and FIG. 5 is a sectional view in the direction of the arrow along the cutting line VV in FIG. 1. In these figures, the roll paper holder 1 of the present invention is composed of a frame wall 2, a front wall 3, and a rotary lid 4, and the frame wall 2 is formed vertically with three walls: side walls 2a, 2a and a rear wall 2b. The lower side of 2b forms an inclined portion 2c and communicates with the opening. Since this inclined portion 2c serves as a support surface for the pull-out roll 10, it is recommended that a slipping material such as a synthetic resin plate be attached to the inside thereof. and the both side walls 2
Support holes 2d, 2d for pivotally supporting a rotary lid 4, which will be described later, are provided on the upper end sides of a, 2a, and slits 2e, 2e are provided as necessary. The slits 2e, 2e can be used to know the remaining amount of the drawer roll 10 or as a return operation window when the preliminary storage roll 9 is opened by mistake, but can be omitted if necessary. Further, a swinging roller 7 is disposed on the opening side at the lower side of both side walls 2a, 2a, and the roller 7 is rotatably supported by a support shaft 7a.
Both ends are freely supported by slit seats 8 provided inside the side walls 2a, 2a, respectively. Furthermore, as shown in FIGS. 2 and 5, this slit seat 8 is provided in an inclined shape with the rear wall 2c side lowered, so that the swinging roller 7 is supported at the lowest position together with the support shaft 7a. Since the roller 7 can move the support shaft 7a along the slit seat 8 by external force, it can operate as a swinging roller.

On the other hand, the front wall 3 forms a sheet paper drawer window 3a, and a hinge pivot is formed on the upper side of the drawer window 3a, to which a presser door 5 is hinged to cover the window 3a. The presser door 5 opens the drawer window 3a by pulling it toward the front in the same way as those used in conventional roll paper holders, and also forms teeth on its lower edge to cut the drawer paper. , and the cut end is recommended to be held while being pressed, but it is also possible to use any other material, such as using the teeth as mere edges or providing a see-through window. Also, the drawer window 3a
The lower edge of the front wall 3 is bent inward to form a curved surface 3b. Both ends of the front wall 3 constructed in this way are formed with side edges bent inward, and when combined with the frame wall 2, After the swing roller 7 and the rotary lid 4, which will be described later, are supported by both side walls 2a, 2a, the bent side edges of the front wall 3 are fitted to the outsides of the side walls 2a, 2a, and assembled. Although not shown, screw through holes may be provided in the side edges to connect the side walls 2a, 2a.

The rotary lid 4, on the other hand, has an arm shape with side plates provided on the outer periphery of a semicircular outer circumferential surface with a straight part formed on the front side, and a projection 4a is provided on a part of both side plates concentrically with the semicircular outer circumferential surface. form each. and the protrusion 4
a is a support hole 2d formed in the side walls 2a, 2a;
This is a protrusion that fits into the support hole 2d, and serves as a support shaft that uses the support hole 2d as a bearing. Furthermore, the protrusion 4a
It is convenient to attach it to the side plate by spot welding, but other means may also be used. As shown in FIG. 2, the rotary lid 4 is formed of an outer circumferential surface extending from the inside of the rear wall 2b constituting the frame wall 2 to the top surface of the front wall 3, and is formed on the front side of the semicircular portion of the outer circumference. A window hole 4b is formed in the center. Furthermore, a sliding door 6 is provided inside the semicircular outer circumferential surface, and the opening and closing door 6 has a width narrower than the width of the rotating lid 4, and a sliding opening/closing door 6 is provided inside a part of the semicircular outer periphery of the rotating lid 4. Both side edges are slidably supported by engagement pieces 4c formed by punching. An operating portion 6a is formed by bending approximately at the center of the front end surface of the opening/closing door 6, and the operating portion is made to protrude from the window hole 4b. Further, the rear end portion 6b of the opening/closing door 6 has both ends connected to the first
As shown in the broken part in the figure, the end is circular and the fifth
As shown in the figure, it serves as a support member for the preliminary roll 9. That is, the opening/closing door 6 prevents the preliminary roll 9 from falling and stores it at the position where the operating part 6a reaches the uppermost edge of the window hole 4b, and moves the operating part 6a to the lowermost edge of the window hole 4b. The stored spare roll 9 can then be opened and dropped.

In the roll paper holder formed in this way, the roll accommodating part is formed vertically, and the upper side can be configured as a spare roll storage part and the lower part can be configured as a pull-out part for a pull-out roll. The swing roller 7 is located in the drawer portion and easily supports the unwinding rotation of the drawer roll 10, so that the drawer roll 10 can freely rotate to feed out the sheet paper. If necessary, an idle roller for supporting the roll 10 may be installed in a part of the inclined part 2c, or this idle roller may be provided in place of the inclined part 2c. Next, when the sheet paper on the pull-out roll 10 is loaded, the core 10a of the roll 10 is supported by the inclined portion 2c and the swinging roller 7 and remains as shown in FIG. 6 (partial operation diagram of FIG. 5). do. When loading the spare roll 9 into the drawer, as shown in FIG. 7 (operation diagram in FIG. 5), first move the operating section 6a of the opening/closing door 6 to the lowest edge within the window hole 4b. , the rear end portion 6b is retracted (from the preliminary roll 9 side) and the preliminary roll 9 is supported.
falls as shown by arrow B. Due to this fall, the remaining core 10a retracts the swinging roller 7 in the direction of arrow C, and only the core 10a is discharged as shown by arrow D from the gap between the retracted position and the tip of the inclined portion 2c. The reserve roll 9 from which the remaining core 10a has been forcibly discharged is supported by the inclined portion 2c and the swinging roller 7. Immediately after the core 10a is discharged, the swinging roller 7 may be in the retracted position, but the swinging roller 7 may be moved slightly by pushing up the roll slightly to find the end of the sheet paper to be pulled out, or by rotating the paper to pull out the paper. 7 descends under its own weight as shown in Figure 7.

Next, when replenishing the storage section with the spare rolls, as shown in FIG. 8 (partial operation diagram of FIG. 5),
The rotary lid 4 is rotated in the direction of arrow E by bringing the operating portion 6a of the opening/closing door 6 to the uppermost edge of the window hole 4b and pushing it further. Then, in a state in which the operation part 6a reaches the upper edge of the rear wall 2b, the rotary lid 4
can be maintained in a wide open position, and new spare rolls 11 can be replenished as shown by arrow F. Next, by closing a part of the rotary lid 4 other than the operating part 6a or the window hole 4b with a finger, the rotary lid 4 can be returned to its original state as shown in FIG. 5, and the spare roll can be replenished. Although the swinging roller 7 is of the self-weight descending type which is freely supported by slit seats 8 and 8 formed with inclined grooves, it is constructed so that the winding core is supported by a biasing spring, and the preliminary roll is The swinging roller 7 may be configured such that the core is ejected against the biasing spring due to the falling weight.

FIG. 9 is a partially cutaway side view showing another embodiment of the present invention, FIG. 10 is a partially cutaway front view on the right side of FIG. 9,
11 and 12 are perspective views of the same essential parts. In these figures, the roll paper holder 1 is housed in a vertically elongated container 26, and is adapted to be attached to a wall or the like at the place of use by screwing it through a hole in a bracket 43. The upper part of the container 26 is provided with a storage part M for storing reserve rolls 9 for storage in the horizontal direction, and the lower part thereof is provided in communication with a drawer part N that supports another drawer roll 10 in use in the horizontal direction. , the upper preliminary roll 9 is provided so as to be able to fall from the storage section M to the drawer section N. In addition, the insertion opening 23 is provided with a cover plate 28 that can be opened and closed around a shaft 44 provided at the upper end of the container 26. When inserting the spare roll 9, the cover plate 28 is opened and then inserted. It looks like the lid is on again. Of course, a separate lid that can be attached and detached may be attached. Also, a detection plate 30 is provided on a part of the cover plate 28 and is rotatable in a seesaw shape in the direction of the arrow around a support shaft 29 provided inside.
is provided, and the left side of the support shaft 29 is connected to the support shaft 29.
Make it heavier than the right side. Therefore, as shown in FIG. 9, when the reserve roll 9 is in the container 26, the left end is placed on the reserve roll 9 and lifted, so the right end enters the cover plate 28, but the reserve roll 9 is not in the storage section. When it is not in M, the left end of the heavier side rotates in the direction of the chain arrow, and the right end of the lighter side is lifted in the direction of the solid arrow, and projects to the outside of the cover plate 28. Therefore, if a mark 31 such as "empty" as shown in FIG. 10 is provided on the other end of the protruding detection plate 30, the presence or absence of the spare roll 9 can be detected at a glance from outside the container 26. The storage section M is configured to be retractable in the direction of releasing the support of the preliminary roll 9 (direction of arrow Y in FIG. 9) about the upper support shaft 32 provided across the side wall of the container 26. (Details will be described later) An upper support member E is provided.
FIG. 11 is an enlarged view of the upper support member E taken out. A torsion coil spring 33 is wound and held at both ends of the upper support shaft 32, and the torsion coil spring 33 is configured for the purpose of tensioning the front side wall surface (the right side wall surface in FIG. 9) of the container 26. A first wire member 33a, and second wire members 33b, 33b forming an angle θ with the first wire member 33a around the upper support shaft 32 and having hook-shaped tips.
are integrally formed. and second wire member 3
3b is a support roll that is engaged with the hook-shaped portion of the first wire member 33 in a state where it is biased by an elastic force in the direction of arrow X, which is generated when the first wire member 33 is pressed against the front inner wall of the container 26. 34, and the support roll 34 supports the preliminary roll 9 in the storage part M by cooperation with the rear inner wall (left side in FIG. 9) 26a of the container 26. Further, the rotation shaft 34a of the support roll 34
is connected to the upper support shaft 32 via a mounting arm 35, and an operating handle 36 that protrudes outside the container is fixed at the center of the upper support shaft 32. When pushed in the direction of arrow Z, the upper support shaft 32 rotates in the direction of arrow U, and as a result, the support roll 34 moves to the second line while resisting the elastic force of the second line member 33b via the mounting arms 35, 35. While hooking the hook-shaped part of member 33b, turn the arrow U in the opposite direction.
It is configured to move in the direction. Although the figure shows an elongated hole 35a, it does not have to be an elongated hole. The movement of the support roll 34 in the direction of the arrow U is a movement in the direction of releasing the support of the reserve roll 9 inserted into the storage section M, and this movement of the support roll 34 releases the support of the reserve roll 9. It means evacuation for release.

FIG. 12 is an enlarged view of the lower support member F provided in the drawer portion N, in which the supply roll 38 is freely mounted on the lower support shaft 37 provided on the side surface of the container wall of the container 26. It is rotatably provided. A torsion coil spring 39 is wound around both ends of the lower support shaft 37. a first wire member 39a, and the first wire member 3
9a and a second wire member 39 forming an angle α around the lower support shaft 37 and having a hook-shaped tip.
b, 39b are integrally formed. The first wire member 39a is connected to the container 26 on the second wire member 39b.
The elastic force in the direction of arrow W generated by being pressed against the front inner wall of
0 is configured to be able to support the pull-out roll 10 in cooperation with a rotatable auxiliary roll 41 provided on the wall of the container 26. Also, drawer roll 1
The paper 10p released from 0 in the direction of the arrow L advances on the supply roll 38, and the cutter is rotated and released in the direction of the arrow T about the fulcrum P at the upper part of the outlet 27 provided at the front of the drawer section. 42 to the outside of the outlet 27. The support roll 40 is made of paper 10p.
It moves in the direction of arrow W (the direction shown by the chain line in FIG. 9), following the surface of the pull-out roll 10 whose diameter decreases as it is taken out, and finally the pull-out roll 10 becomes the core. Even when only the core 10a is used, the core 10a can be supported together with the auxiliary roll 41, that is, the auxiliary roll 41 and the support roll 4
It is configured to be able to follow until the interval 0 becomes smaller than the core diameter 10a. Also, the winding core 10a
When the roll 40 is discharged, the roll 40 is retracted in the direction of increasing the distance, that is, in the opposite direction to the arrow W. The effect of this will be described further below.

Next, the operating status of each part will be explained. 1st
Figures 3 and 14 show the roll paper holder 1 of this embodiment.
FIG. 13 shows the operating state of the upper support member E, and FIG. 14 shows the operating state of the lower support member F. Figures 13 and 14 below and Figures 9 and 10 above.
The operation of the roll paper holder 1 will be described in detail with reference to the drawings. First, in Figure 9, mark 3
After confirming the character “empty” written in 1, lift the cover plate 28 and insert the storage part M from the insertion opening 23.
Insert and attach the spare roll 9 to. The attached preliminary roll 9 is attached to the support roll 34 and the inner wall 2 of the container 26.
6a and is attached to the storage part M, but since its weight is overcome by the elastic force of the torsion coil spring 23 in the direction of the arrow X, it never falls into the lower drawer part N of the communication structure. On the other hand, in the drawer section N, the drawer roll 10 is supported by the support roll 40 and the auxiliary roll 41 and is attached to the drawer section N.
is placed and supported on the auxiliary roll 41 and the support roll 40, and is free to rotate leftward or rightward without being subjected to any restraining force other than the own weight of the pull-out roll 10. In FIG. 9, in order to take out the paper 10p in the direction of the arrow, that is, from below the draw-out roll 10 through the supply roll 38 and out of the outlet 27, the pull-out roll 10 is released from rotating counterclockwise due to its tensile force. An example is shown. On the other hand, when the paper is rewound in a clockwise direction,
It can also be pulled out from above as shown by the broken line. 1st
FIG. 4 shows the operating state of the lower support member F that changes as the diameter of the pull-out roll 10 decreases. That is, the support roll 40 follows and contacts the surface of the pull-out roll 10 from beginning to end, and when the diameter of the pull-out roll 10 decreases in the direction of the arrow to the state shown by the dashed line, the support roll 48 also moves in the direction of the arrow W due to the elastic force of the spring. It moves to the position indicated by the chain line and still supports the pull-out roll 10. When the paper 10 is used up, the drawer roll 10 shown by the dashed line
is already in a state where only the winding core 10a is present, but if the interval between the auxiliary roll 41 and the support roll 40 is kept smaller than the diameter of the winding core 10a in this state, the winding core 10a will be removed from the discharge port. 24 without falling under its own weight and is held at the position shown by the dashed-dotted line. In this state, the operating handle 36 is pushed in the direction of arrow Z with the intention of replenishing the drawer N with the spare roll 9 mounted on the storage section M. Then, the operating handle 36 reaches the position shown by the chain line in FIG. The pull-out roll 10 loses its support in the storage section M and falls downward as indicated by an arrow S. The falling reserve roll 9 collides with the winding core 10a just before falling onto the support roll 40 and the auxiliary roll 41, so the support roll 40 pushed by the collided winding core 10a momentarily moves in the direction of arrow H. Since the winding core 10a is retracted in a direction that widens the roll interval shown, the winding core 10a loses its support, falls downward, and is discharged from the outlet 24. After the winding core 10a falls, the newly replenished drawer roll 10 is moved to the auxiliary roll 41.
It is mounted on the drawer part N while being placed on the support roll 40 which is in the retracted position (solid line position).
Note that when the pull-out roll 10 falls from the storage section M, the upper support member E immediately returns to the position shown in solid line in FIG. 9 to prepare for mounting the next spare roll 9. When using the drawer roll 10, cutter 42
is lifted in the direction of arrow T to take out the winding opening of the paper 10p from the surface of the pull-out roll 10 and take it out through the supply roll 38 and out of the take-out port 27.
With cutter 42 down again, paper 10
Just cut p to the required length. Note that FIG. 9 shows the case where the pull-out roll 10 is taken out from the direction in which the rotation is released in the direction of the arrow L, but if the rotation is released in the opposite direction to the arrow L, the paper 10p is taken out from the supply roll as shown by the chain line from above. It is possible to release and take out the route directly leading to the cutter 42 without passing through the cutter 38. In other words, even if the loading direction of the pull-out roll 10 is reversed, since no binding force other than the own weight of the pull-out roll 10 acts on the pull-out portion N, rotation can be freely released, and the loading direction can be reversed as before. There is no need to check carefully. Thereafter, depending on the usage status of the paper 10p, replenishment of the drawer roll 10 into the storage section M, loading of the paper roll into the drawer section N, and discharge of the used core are repeated according to the aforementioned procedure. In this embodiment, the preliminary roll 9 is supported in the storage part M by the container wall of the container 26 and the support roll 34, and the pull-out roll 10 is supported by the auxiliary roller 41 attached to a shaft fixed to the wall of the container 26 and the support. roll 4
Although the example is shown in which the roller 41 is used, another auxiliary roll may be provided in place of the vessel wall, or a vessel wall may be used in place of the auxiliary roll 41.

Since the roll paper holder of the present invention is constructed in this way, there is no need to remove the remaining core when filling the preliminary roll, and filling can be performed automatically by simply slightly operating the operating section.
Further, since the pull-out roll is supported by a rotatable roller, it can be smoothly rotated in the free direction and pulled out in the free direction. That is, when replenishing the rolls, it is possible to easily replenish the rolls without considering the pulling direction.
