Description

[Detailed description of the invention] (b) Industrial application fields The present invention relates to a sheet paper roll for toilet seats.

(B) Conventional technology Conventionally, in consideration of hygiene, sheet paper rolls capable of continuously supplying sheet paper onto the toilet seat have been developed as follows:
There is one of the form described in Japanese Patent No. 9600.

FIG. 10 shows the composition of the sheet paper roll described in the former (Utility Model Application Publication No. 155399/1989).

In the figure, a is a long sheet paper rewound from a sheet paper roll, and the sheet paper a has a width slightly wider than that of the toilet seat, and has perforations C for cutting at slightly longer intervals than the toilet seat. A rectangular cutout perforation d is provided on the inside of the toilet seat.

In use, the sheet paper roll color sheet paper a is loaded by a desired sheet paper supply device.
is rolled out onto the toilet seat, the rear end of the sheet paper a is cut, and a rectangular opening is created by separating the cutting perforation d. Thereafter, the user sits on the toilet seat and defecates, and after defecating, the sheet paper a can be washed away with water along with the pickled material.

Moreover, FIG. 11 shows a sheet paper roll described in the latter (Utility Model Application Publication No. 55-179600).
The sheet paper a fed out from the tohehar roll is the sheet paper described in the above-mentioned Japanese Utility Model Publication No. 155399/1983.
-/< - It has the same structure as bar a, but is different in that an opening e is provided in the center from the beginning. And when it is used, it is used in the same manner as the above-mentioned sheet paper a.

(c) Problems to be Solved by the Invention However, such sheet paper rolls still had the following problems.

That is, the former (Utility Model Application Publication No. 60-155399) had the following problems.

■ Sheet paper a had to be picked up by hand and thrown into the toilet bowl after use, which was extremely unsanitary.

(2) Since a rectangular opening is formed in the sheet paper a, a sufficiently large opening area cannot be secured, and there is a risk that excrement may adhere to the sheet paper a during toilet use.

■ Sheet paper a has a completely circular cutout perforation d, so there is no stiffness, and sheet paper a
When the sheet paper a is fed out from the sheet paper roll, the sheet paper a may be bent, or it may be difficult to roll the sheet paper when manufacturing the sheet paper roll.

On the other hand, the sheet paper roll described in the latter (Japanese Utility Model Publication No. 55-179600) had the following problems.

In other words, since sheet paper a is completely cut out, it is impossible to process it into a roll, and even if it were to be made into a roll, the center would be depressed and sheet paper a would be twisted or folded when being fed out. Smooth supply was not possible.

An object of the present invention is to provide a sheet paper roll that can solve the above problems.

(d) Means for Solving the Problems The present invention provides a plurality of horseshoe-shaped cut-out perforations that are spaced at predetermined intervals in the longitudinal direction in the center of a long sheet paper and that match the inner shape of the toilet seat body. The present invention relates to a sheet paper roll for a toilet seat, characterized in that a non-perforated portion is provided between both rear ends of each perforation, and the sheet paper is wound onto a roll.

(E) Actions and Effects With the configuration described above, the present invention has the following effects.

■Each cutout perforation has a horseshoe shape, and a non-perforated part is provided between the rear ends of the perforation, so when in use, the cutout part The tip of the toilet is immersed in the standing water in the flush toilet bowl, while its base is connected to the sheet paper through a non-perforated part.

Therefore, when you flush the toilet after using the toilet, the cut-out part and the sheet paper on the toilet seat, which is an integral part of it, are automatically removed by the flushing water into the flushing water in the toilet bowl, without having to dispose of the sheet paper manually. They get caught up in water and are washed away along with their excrement.

■Multiple horseshoe-shaped cut-out perforations are provided in the center of the sheet paper at predetermined intervals in the longitudinal direction and match the inside shape of the toilet seat body, so when the perforations are separated during use, It is possible to form a large opening and prevent excrement from adhering to the sheet paper.

■Each cutout perforation has a horseshoe shape, and a non-perforated part is provided between the rear ends of the perforation, so it is possible to give the sheet paper sufficient stiffness, making it easy to feed out the sheet paper. It is possible to extremely easily bend the paper at the time of production and roll processing during the production of sheet paper rolls.

■The sheet paper is continuously rolled, so there is no need to blow it away in the wind or hold it down with your hands each time you use it.

■Since the sheet paper is continuously rolled, it does not cling to your butt when you stand up after using the toilet, making it hygienic.

(f) Examples The present invention will now be explained in detail based on examples shown in the accompanying drawings.

In FIG. 1, R indicates a sheet paper roll, and by unwinding the sheet paper roll R, a long sheet paper P is formed.

The reason why the sheet paper P is formed from the sheet paper roll R is to compactly store the sheet paper P for a large number of people in the functional part casing H provided at the rear of the toilet seat body 11.

The sheet paper P has a plurality of cut-out perforations in the center thereof, spaced at predetermined intervals in the longitudinal direction, in a shape that matches the inner shape of the toilet seat main body 2 placed on the flush toilet bowl 1, that is, a horseshoe shape. 3 is provided, and by cutting out along the perforation 3, an opening O communicating with the inside of the flush toilet bowl 1 can be provided.

In addition, in this embodiment, the perforation 3 is not completely annular, and a non-perforation part 4 is formed between both ends of the rear part, and the perforation 3 is continuous. (However, perforations are formed at regular intervals, and the rest are cuts, so they can be easily cut out when used.

Therefore, when the perforation 3 is cut out, the cutout part 5 is
It drips into the flush toilet bowl 1, and its lower end is submerged in standing water.

In addition, the reason why the sheet paper P is not completely perforated but has the non-perforated part 4 and the cutout perforation 3 is that if the sheet paper P is made perforated, there will be no stiffness, and the sheet paper P will be supplied onto the toilet seat body 2. This is because it is almost impossible to bend or form a sheet paper roll R when doing so.

In addition, the sheet paper P provided with the perforations 3 and non-perforations 4 has sufficient stiffness, so that both the automatic feeding of the sheet paper P and the roll processing during the production of the sheet paper roll R are possible. easily possible.

Furthermore, as shown in FIG.
A position detection through hole 6 is provided between the front end of the sheet paper roll R and a position detection sensor 83, which will be described later, to detect the through hole 6, thereby controlling the feeding operation of the sheet paper P from the sheet paper roll R. can be controlled.

Note that instead of the through holes 6, position detection marks may be provided at arbitrary locations on the sheet paper P at intervals in the longitudinal direction.

Next, with reference to FIGS. 2 to 5, the configuration of the sheet paper automatic supply toilet seat A equipped with the sheet paper roll R according to the present invention will be explained, and then the sheet paper roll in the sheet paper automatic supply toilet seat A will be explained. How to use R will be explained.

As shown in Fig. 2, the sheet paper automatic supply toilet seat A is
A toilet seat body 2 is placed on the flush toilet bowl 1 so as to be openable and closable, and a toilet seat body 2 is fixedly placed on the rear part of the flush toilet bowl 1, and the rear part of the toilet seat body 2 is rotatable in the vertical direction by a pivot 12 at the front part. It is formed from a functional part 13 which is pivotally connected to the functional part 13.

As shown in FIGS. 3 to 6, the functional part 13 is attached to the rear part of the flush toilet bowl 1 and has one end of a rectangular plate bent at a right angle toward the front of the toilet seat main body 2 in plan view. It is formed from an L-shaped mounting board 20, a sheet paper feeding mechanism section C, a sheet paper cutting mechanism section, a sheet paper roll storage section E, a control section F, and an operation section G mounted on the mounting board 20. There is.

First, the configuration of the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section will be explained. As is clear from FIGS. is installed upright, and the same support plate 2
Between 1.22 and 22, a plurality of rotating shafts are rotatably supported horizontally.

That is, 23 is a sheet paper feeding shaft that is horizontally suspended between the upper front ends of the support plates 21 and 21, and a large number of feeding rollers 24 are attached to the feeding shaft 23 at predetermined intervals in the axial direction.

The feeding roller 24 cooperates with a pressing roller 71, which will be described later, to press and clamp the drawn end of the sheet paper P to transfer the sheet paper P from the sheet paper roll storage section E onto the toilet seat main body 2. Can be fed and fed.

In addition, since the large number of feeding rollers 24 are arranged in the axial direction at predetermined intervals, the sheet paper P can be fed out at the same speed and with a uniform pressing force over the entire width, so that the sheet paper P is not kinked. It effectively prevents

In addition, all of the many feeding rollers 24 have O-rings 24.
A is attached to prevent the sheet paper P from spinning or slipping when feeding out.

In addition, such idle rotation and slipping can be prevented by using the feeding roller 24.
This can also be achieved by making the device itself made of rubber, or by using a rubber belt or the like.

In addition, in FIGS. 5 and 6, reference numeral 25 indicates a support plate 22.
A cutting blade moving shaft formed from a screw punch is horizontally suspended between the lower front ends of the cutting blade 22, and a cutting blade moving guide shaft 26 formed from a solid rod is provided directly above the moving shaft 25.

A cutting blade mounting plate 27 is attached to the cutting blade movement shaft 25 and the cutting blade movement guide shaft 26.
is attached to the cutting blade moving shaft 25.

Further, a disk-shaped cutting blade 2 is provided at the upper end of the cutting blade mounting plate 27.
8 is rotatably supported.

With this configuration, when the cutting blade moving shaft 25 is rotated,
The cutting blade 28 reciprocates in the axial direction together with the cutting blade mounting plate 27, and can instantly cut the sheet paper P.

In addition, instead of the above-described structure, the mechanism for moving the cutting blade 28 can be made such that an endless wire or an endless belt is driven by a rotary motor so that it can reciprocate in the left and right width direction, and the cutting blade 28 is moved on the endless wire or the like. It can also be configured by binding.

In addition, a method of cutting the sheet paper P by reciprocating the cutting blade 28 is described using a rotating shaft 93 having a cutting blade 90 and a cutting blade receiving groove 91 as shown in FIGS. 7 and 8, respectively.
．． By rotating 94, it is also possible to cut the sheet paper P. At this time, the above-mentioned cutting by rotation at 180° can be changed to an arbitrary angle.

Note that FIG. 7 shows the rotating shafts 93 and 94 in a state in which the sheet paper P is fed, and FIG.

is the rotating shaft 93 in the state of cutting the sheet paper P.
．． 94 is shown. Further, 95 and 96 indicate a holding roller and a feeding roller, respectively.

Further, in the embodiment, the cutting blade 28 is shaped like a disc in consideration of durability, but it can also be shaped like a flat plate.

Further, in FIGS. 3 and 5, reference numeral 30 denotes a rotation motor that can selectively rotate the sheet paper feeding shaft 23 and the cutting blade moving shaft 25 via a clutch mechanism M. Sheet paper feeding shaft 2
3 and the cutting blade moving axis 25 is switched by the rotation motor 30.
This is done by switching between forward and reverse rotation. In addition,
In this embodiment, the rotation motor 30 is connected to the − side support plate 21
is fixed to.

Then, the sheet paper feeding shaft 2 is connected to the rotary motor 30.
3, the rotation of the gear 31 fixed to the output shaft of the rotary motor 30 is transmitted to the gear train 32°33.34.
, 35, 36 to the gear 37 fixed to the sheet paper feed shaft 23.

On the other hand, the rotational force is transmitted from the rotary motor 30 to the cutting blade moving shaft 25 by fixing a gear 38 to the cutting blade moving shaft 25 and using a gear 32 that meshes with the gear 33 by a clutch mechanism M.
This can be achieved by releasing the mesh by reversing the rotation motor 30 and by meshing the gear 38 with the gear 39 that meshes with the gear 32a that is integral with the gear 32.

That is, the rotational force of the rotary motor 30 is
2a, 39.38 to the cutting blade moving shaft 25.

With this configuration, the single rotation motor 30 is driven by the operation of the clutch mechanism, and the feeding operation of the sheet paper P and the operation of cutting the sheet paper P are selected by driving the rotation motor 30 in forward and reverse rotations. This can be done sequentially.

However, the feeding operation and the cutting operation can also each be performed using dedicated motors.

Note that the rotational force of the rotary motor 30 can be transmitted to the sheet paper feeding shaft 23 and the cutting blade moving shaft 25 using a belt or a wire instead of using a gear train.

Next, the configuration of the control section F that controls the operations of the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section will be explained.

As shown in FIGS. 3 and 5, a control unit mounting plate 50 is erected on a front extending portion 20a extending forward from one end of the mounting board 20. On the board 50,
A control panel 51 is attached to control the operation of the rotation motor 30 described above, and forms a control section F. Note that a transformer 51a is also integrally attached to the control panel 51.

Further, the sheet paper feeding mechanism section C, the sheet paper cutting mechanism section, and the control section F arranged on the above-mentioned mounting board 20 are integrated into an L-shaped cover casing 60 having the same external shape as the mounting board 20. is surrounded by.

Next, the operation section G will be explained. As is most obvious from FIG. 5, the operation section G is provided in the cover casing 60 at a location above the control section F.
The operation section G includes a push button 619 for feeding sheet paper, a power lamp 62 consisting of a light emitting diode, etc., on the upper surface of the operation section mounting plate 59 disposed inside the cover casing 60.
It is constructed by installing a paper replenishment lamp 631, a paper jam lamp 64, etc., which have a warning function in the event of an abnormality such as a paper jam or paper replenishment.

Note that a buzzer or the like may be installed instead of the replenishment lamp 63 or the like.

Further, above the sheet paper feeding mechanism section C, a sheet paper roll storage section E is provided, as shown in FIGS. 4, 5, and 6.

The sheet paper roll storage section E includes a sheet paper roll storage box 70 that is freely attached to the space formed between the left and right side walls 65 and 66 that are integrally provided on the left and right upper surfaces of the cover casing 60. It is formed of a digit sheet paper roll R that is replaceably mounted in the storage box 70, and a pressing roller 71 that is horizontally suspended in front of the lower part of the sheet paper roll storage box 70.

In the above configuration, the sheet paper roll storage box 70 has openings on both left and right end walls 70a and 70b that communicate with openings at both ends of the center axis of the sheet paper roll R, and inside the openings, there are openings in the left and right end walls 70a and 70b. 70b
Rotatably and removably sheet paper roll R
A connecting plug 72 is provided for connecting the sheet paper roll R, and by moving the connecting plug 72 forward and backward in the axial direction, the sheet paper roll R can be easily connected and removed.

The left and right connecting plugs 72 are prevented from coming off by the left and right end walls 65 and 66 on the cover casing 60.

Further, the press roller 71 is in pressure contact with the feed roller 24 attached to the sheet paper feed shaft 23 of the sheet paper feed mechanism section C mentioned above, and the gear 74 fixed to one end of the press roller 71 is in contact with the feed roller 24 attached to the sheet paper feed shaft 23 of the sheet paper feed mechanism section C. It meshes with a gear 73 fixed to the corresponding end of the shaft 23.

With this configuration, when the sheet paper feeding shaft 23 and the feeding roller 24 rotate in one direction, the presser roller 7
1 can be rotated in the opposite direction via gears 73 and 74 to unwind the sheet paper P from the sheet paper roll R.

Further, an O-ring 71b is similarly attached to the holding roller 71 in accordance with a predetermined position of the feeding roller 24, and effectively prevents idle rotation, slipping, and twisting when feeding the sheet paper P. .

Furthermore, as shown in FIG. 6, both ends of the pressing roller 71 are connected to a swinging lever 7 whose base end is pivoted to the lower part of the front wall of the sheet paper roll storage box 70 so as to be able to swing freely in the vertical direction.
It is pivotally supported at the tip of 1a.

Further, the pressing roller 71 is in pressure contact with the feeding roller 24 and is made of a material with a heavy specific gravity in order to reliably feed the sheet paper P from the sheet paper roll R.

With this configuration, the pressing roller 71 comes into pressure contact with the feeding roller 24 due to its own weight.

Further, as shown in FIG. 6, a slit 75 for taking out sheet paper is formed between the upper wall 60c of the cover casing 60 and the lower end of the front wall 70c of the sheet paper roll storage box 70.

Therefore, as shown in FIG.
After the sheet paper roll R is bent outward and uncurled, it passes between the pressing roller 71 and the feeding roller 24, and then is fed onto the toilet seat main body 11 through the sheet paper taking-out slit 75.

Note that the sheet paper roll storage box 70 and the above-mentioned cover casing 60 are integrated to form a functional unit casing H.

Further, in FIG. 3, 83 is a position detection sensor provided at the center of the front wall of the cover casing 60, and the position detection sensor 83 detects when the sheet paper P is unwound for a predetermined length from the sheet paper roll R. At the same time, detecting the through hole 6 and stopping the operation of the sheet paper feeding mechanism C,
The sheet paper P can be accurately supplied and positioned on the toilet seat body 11.

In addition, in FIG. 3, reference numeral 84 is a seating sensor consisting of a reflective infrared sensor provided at the front of one end of the mounting board 20, and when the user leaves the toilet seat body 2 after sitting on the toilet seat body 2, a detection signal is sent. is generated, the control unit F is activated, and the cutting blade 28 is reciprocated in the axial direction, thereby instantaneously cutting the sheet paper P.

The seating sensor 84 can be integrated into the automatic sheet paper supplying toilet seat A or can be separated and made into a separate body, depending on the usage conditions and usage environment.

In addition, in FIG. 3, 85 indicates the toilet seat body 11 when the toilet seat body 2 is in a state where it cannot be seated (when the toilet seat body 2 is independent)
This sensor is for stopping the supply of sheet paper P by cutting off the power to the rotation motor 30 when the detection is removed from the seat, and detects the toilet seat body 2 only when the toilet seat body 2 is in a state where the toilet seat body 2 can be seated. The system shall be placed in an operable state.

Note that instead of the paper jam prevention sensor 85, a microswitch, a limit switch, or the like may be used.

Hereinafter, a sheet paper automatic supply toilet seat A having the above configuration and equipped with a sheet paper roll R according to the present invention will be described.
The operation will be explained with reference to the flowchart shown in FIG.

First, turn on the power using the power switch S, and check whether the power lamp 62 is lit (100).

After checking, press the sheet paper feeding push button 61 (
101).

Since the power switch S is not particularly required during use,
It is provided on the back surface of the front part of one end of the mounting board 20 (see FIG. 5).

At this point, if there is no paper jam or there is no sheet paper roll R, the paper jam lamp 64 or the paper replenishment lamp 63 of the operating section G lights up (102> (103)).

When there is no paper jam and there is enough sheet paper roll R, or when the paper jam is cleared, the sheet paper roll Rt-sheet paper roll storage box 7
When set to 0, the control unit F operates to drive the rotary motor 30 and the clutch mechanism M to select the gear train that connects the feed roller 24 and the presser roller 71.

Thereby, the rotation of the rotary motor 30 is transmitted to the delivery roller 24 and the holding roller 71 via the gear train. By the way, since the feed roller 24 and the press roller 71 rotate in opposite directions and hold the sheet paper P in a pressed state, the sheet paper P
is unwound from the sheet paper roll R in the sheet paper roll storage box 70.

That is, as shown in FIG. 6, the sheet paper P is once bent upward and outward by the presser roller 71 to uncurl the sheet paper roll R, and then
Passing between the feeding roller 24 and the pressing roller 71,
Then, through the sheet paper ejection slit 75,
It will be delivered and supplied onto the toilet seat body 2.

In addition, in this feeding operation, when the sheet paper P is fed out onto the toilet seat main body 2 by a predetermined length, the position detection sensor 83 detects the position detection through hole 6 provided in the center of the sheet paper P. , actuates the control unit F to stop the rotation of the rotary motor 30. As a result, the feeding and feeding operation of the sheet paper P by the feeding roller 24 and the pressing roller 71 is also stopped instantaneously, and the sheet paper P is fed onto the toilet seat body 2 by an accurate predetermined length (104 ).

Note that the sheet paper P is curled upward at the stage when it is unwound from the sheet paper roll R, but in this embodiment, the above-mentioned upward curling of the sheet paper P is reversed by the press roller 71 and reversed. The paper can be curled downward, and then sent out onto the toilet seat main body 2 in a downward state from the paper take-out slit 75.

Therefore, it is possible to reliably prevent a paper jam accident in which the sheet paper P curls upward and is fed only into the functional part casing H and is not fed onto the toilet seat body 2, and it is also possible to prevent paper jams such as sheet paper P curling upward and being fed only into the functional part casing H and not being fed onto the toilet seat body 2. It is possible to prevent the sheet paper P from being curled near the paper take-out slit 75 without being fed to a predetermined position.

After that, the user inserts the sheet paper P along perforation 3.
The center part is cut off leaving only the non-perforated part 4, and the cut-off part 5 hangs downward, and its tip is placed in the standing water in the flush toilet bowl 1.

As described above, in this embodiment, the sheet paper P can be fed to the required length onto the toilet seat main body 2 by a one-touch operation. In addition, in this state, the sheet paper P is not cut from the sheet paper roll R, so there is no need to worry about the contact with the flush toilet l or to perform positioning.

Furthermore, even if the shingle feed push button 61 is pressed while the sheet paper supply is completed due to the operation of the control unit F,
The next sheet paper P is not fed out, taking into consideration prevention of tampering and determination of usability.

Thereafter, the user sits on the sheet paper P on the toilet seat body 2 (105).

When the user sits on the toilet seat body 2 and stands up from the toilet seat body 2 after urinating (106), the seating sensor 84 detects that the user has left the toilet seat body 2, and uses the detection signal to activate the control unit F. At the same time, the clutch mechanism M is activated to connect the rotary motor 30 with the cutting blade moving shaft 25 via a gear train, and the cutting blade 28 is reciprocated to cut the sheet paper. Instantly disconnect P (107).

In the above operation, unless the seat sensor 84 senses the position for at least 10 consecutive seconds (that is, unless the user remains seated for 10 seconds), even if the user stands up from the toilet seat body 11, the control will not be performed. Section F is made inoperable.

Therefore, consideration is given to preventing the cutting operation of the sheet paper P due to erroneous sensing, such as sensing the sheet paper P in the middle of being fed out or sensing an instantaneous motion of the user other than sitting down.

Note that the setting timing of the seating sensor 84 and the time lag for preventing malfunctions can be set according to the environment by the control section F.

Thereafter, the cleaning device is driven to clean the inside of the flush toilet bowl 1, and the force of the flushing water entrains the cut-off portion 5 of the sheet paper P together with the flushing water and dirt, allowing it to flow out (10B).

In addition, when used in a public place such as a theater, it is also possible to automatically supply the sheet paper P onto the toilet seat main body 2 for the next user after the series of operations described above is completed. It is.

With the configuration and operation described above, this embodiment has the following features:
The following effects will be achieved.

■Each cutout perforation 3 has a horseshoe shape, and a non-perforated part 4 is provided between both ends of the rear part of the perforation 3, so when the perforation 3 is cut out and an opening is created, the part to be separated is The tip of the toilet bowl 5 is immersed in the standing water in the flush toilet bowl 1, while the base thereof is connected to the sheet paper P via a non-perforated line 4.

Therefore, when washing with water after using the toilet, the washing water automatically removes the sheet paper P on the detached portion 5 and the toilet seat main body 2, which is integrated with it, without having to dispose of the sheet paper P manually. The water-soluble sheet paper P is caught in the flushing water in the flush toilet bowl 1 and washed away together with the excrement.

■A plurality of horseshoe-shaped cutout perforations 3 that match the inner shape of the toilet seat body 2 are provided at a predetermined interval in the longitudinal direction in the center of the sheet paper P, so when the perforations 3 are cut out, Therefore, excrement etc. do not adhere to the sheet paper P.

■Each item cutting perforation 3 has a horseshoe shape, and a non-perforated part 4 is provided between both ends of the rear part of the perforation 3, so it is possible to give the sheet paper P sufficient stiffness. It is possible to prevent bending when feeding out the sheet paper P,
Roll processing during production of the sheet paper roll R can be performed extremely easily.
