Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a toilet seat that automatically feeds sheet paper.

(B) Prior Art Conventionally, as a device for setting sheet paper on a toilet seat in consideration of hygiene, there is a toilet seat cover supplying device described in Japanese Utility Model Application Publication No. 155399/1983.

The device has a size and shape that can cover the top surface of the toilet seat, and it winds up or folds a continuous sheet of paper to accommodate it, and continuously rewinds the paper. A sheet-shaped paper holder adapted to be fed out, and a feeding roller on the paper feeding side of the holder for feeding a predetermined length of the paper forward near the top surface of the toilet seat, and The present invention is characterized by a structure consisting of a paper feeding cutting section equipped with a cutting blade for cutting the rear end of a paper of a predetermined length.

(c) Problems to be solved by the invention However, in such conventional devices, sheet paper is cut by using a similarly long movable blade for cutting a long fixed blade whose length is longer than the width of the sheet paper. Cutting is performed by lowering a blade from above, ie, so-called push-cutting, which has the following problems.

Since the movable blade, which is a heavy object, must be raised and lowered, the drive mechanism becomes large, and in combination with the long movable blade and fixed blade, the cutting mechanism becomes large.

Even if only a portion of the movable blade or fixed blade becomes dull, the entire movable blade and/or fixed blade must be replaced, significantly increasing maintenance costs.

An object of the present invention is to provide an automatic sheet paper supply toilet seat that can solve the above problems.

(d) Means for solving the problem The present invention involves feeding sheet paper to a predetermined length onto the toilet seat body from a sheet paper roll stored in a functional casing provided at the rear of the toilet seat body.
In a toilet seat that automatically supplies sheet paper to be cut,
A cutting blade holder is arranged at a position facing a cutting blade movable in the width direction perpendicular to the feeding direction of the sheet paper and the sheet paper, and a cutting blade guide groove is provided in the cutting blade holder. The present invention relates to an automatic sheet paper supplying toilet seat having particular features.

The present invention is also characterized in that the cutting blade holder is made of an elastic material.

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

The sheet paper can be cut with a cutting blade that is movable in the width direction perpendicular to the feeding direction of the sheet paper, so the cutting blade can be used to cut into lightweight pieces with a cutting blade surface that is at least as thick as the sheet paper. Since the moving device can be formed in a simple manner, the cutting mechanism can be made compact.

In addition, the sheet paper can be cut with a cutting blade that is movable in the width direction perpendicular to the feeding direction of the sheet paper. Since it can be formed from a small piece, even if the cutting blade becomes dull, it can be easily and inexpensively replaced, and maintenance can be performed extremely easily and inexpensively.

Also, if the cutting blade is made of ceramic etc.
It can also be made maintenance free.

When cutting the sheet paper, the cutting blade holder supports the cut portion of the sheet paper to be cut by the cutting blade, so that the sheet paper can be cut reliably and easily.

By providing the cutting blade guide groove in the cutting blade holder, sheet paper can be cut more reliably.

Furthermore, by forming the cutting blade holder from an elastic material, the durability of the cutting blade and the cutting blade holder can be improved.

(f) Examples The present invention will be described in detail below based on examples shown in the attached drawings.

FIG. 1 shows the overall configuration of a toilet B equipped with an automatic sheet paper supplying toilet seat A according to the present invention. It is placed on.

The structure of the automatic sheet paper supply toilet seat A will be explained in detail with reference to FIGS. 2 to 5.

As shown in the figure, the sheet paper automatic supply toilet seat A includes a toilet seat main body 11 placed on the flush toilet bowl 10 so as to be openable and closable, and a toilet seat main body 11 placed in a fixed state on the rear part of the flush toilet bowl 10, and a toilet seat main body 11 on the front part. Pivot the rear part of
2, and a functional part 13 which is rotatably connected in the vertical direction.

As shown in FIGS. 2 to 5, the functional unit 13
is an L-shaped mounting board 20 that is attached to the rear of the flush toilet 10 and has one end of a rectangular plate bent at a right angle toward the front of the toilet seat body 11 when viewed from above.
It is formed of a sheet paper feeding mechanism section C, a sheet paper cutting mechanism section D, a sheet paper roll storage section E, a control section F, and an operation section G, which are mounted on the same mounting board 20.

First, the configuration of the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section D will be explained. As is clear from FIGS. 2 and 3, the mounting board 20 has rotating shaft support plates 21 and 2 on both ends thereof
2 is installed upright, and between the support plates 21 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, 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 (to 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 to the toilet seat main body 11.
It can be fed upwards 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, and the sheet paper P
This effectively prevents the occurrence of kinks.

In addition, O-rings 24a are attached to all of the many feeding rollers 24 to prevent idle rotation and slippage when feeding the sheet paper P.
Note that such idling and slipping can be prevented by making the feeding roller 24 itself made of rubber, or by using a rubber belt or the like.

Further, in FIGS. 4 and 5, 25 is a cutting blade moving shaft formed from a screw rod and horizontally suspended between the lower front ends of the support plates 22, 22. A formed cutting blade movement guide shaft 26 is provided.

A cutting blade mount 27 is attached to the cutting blade movement shaft 25 and the cutting blade movement guide shaft 26, and the mount 27 is screwed onto the cutting blade movement shaft 25.

Further, a disk-shaped cutting blade 28 is rotatably supported at the upper end of the cutting blade mounting base 27.

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 base 27, and the sheet paper P can be cut instantly.

In addition, since the cutting blade 28 is disk-shaped, the cutting blade 28 cuts the sheet paper P while rotating, and the cutting blade surface is evenly worn over the entire circumference. Therefore, the life of the cutting blade 28 can be extended, and maintenance can be facilitated.

Furthermore, in this embodiment, FIGS.
As is clear from the figure, the paper support surface L is located at a position facing the cutting blade 28 through the sheet paper P.
A cutting blade holder 28a having a diameter is provided.

The cutting blade holder 28a is preferably made of an elastic material such as rubber, taking into account its elasticity.

With this configuration, when cutting the sheet paper P, the cutting blade holder 28a supports the cut portion of the sheet paper P that is about to be cut by the cutting blade 28, so that the sheet paper P can be cut reliably and easily. can do.

Incidentally, during such cutting, the sheet paper can be cut more reliably by providing a cutting blade guide groove 28b on the paper supporting surface of the cutting blade holder 28a, as shown in FIG.

In addition to the shape shown in FIG. 6, the shape of the cutting blade guide groove 28b can also be any suitable shape, such as a V-groove shape.

Further, the gap between the upper surface of the cover casing 60 and the lower surface of the cutting blade holder 28a may be made large enough to allow the sheet paper P to pass through. It can be configured to be able to move up and down, so that it can be lowered during cutting to support the sheet paper P, and can also be raised and returned to its original standby state after cutting.

In addition, instead of the above-described structure, the mechanism for moving the cutting blade 28 is made to be able to reciprocate in the left and right width direction by driving an endless wire or an endless belt with a rotary motor. It can also be constructed by binding.

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.

In addition, in FIGS. 2 and 4, 30 is the sheet paper feeding shaft 23 and the cutting blade moving shaft 25.
is a rotary motor that can be selectively rotated via a clutch mechanism M, and the clutch mechanism M
Switching between the sheet paper feeding shaft 23 and the cutting blade moving shaft 25 is performed by switching the rotary motor 30 between forward and reverse rotation. In addition, in this embodiment, the rotation motor 30 is connected to the one side support plate 2.
It is fixed at 1.

The rotational force is transmitted from the rotary motor 30 to the sheet paper feeding shaft 23 by the rotary motor 30.
This is accomplished by transmitting the rotation of the gear 31 fixed to the output shaft of the sheet paper through gear trains 32, 33, 34, 35, and 36 to the gear 37 fixed to the sheet paper feeding shaft 23.

On the other hand, the rotational force from the rotary motor 30 to the cutting blade moving shaft 25 is transmitted to the cutting blade moving shaft 25 by a gear 38.
and the gear 3 is fixed by the clutch mechanism M.
This can be done by releasing the gear 32 that meshes with the gear 38 from the mesh by reversing the rotating motor 30, and also meshing the gear 38 with the gear 39 that meshes with the gear 32a that is integrated with the gear 32.

That is, the rotational force of the rotary motor 30 is transmitted through the gears 31,
It is transmitted to the cutting blade moving shaft 25 via 32, 32a, 39, and 38.

With this configuration, the single rotary motor 30 is driven by the operation of the clutch mechanism M, and the feeding operation of the sheet paper P and the feeding operation of the sheet paper P are performed by driving the rotary motor 30 in forward and reverse directions. The cutting operation can be performed sequentially.

Moreover, the feeding operation of the sheet paper P and the cutting operation of the sheet paper P can be performed using dedicated motors, respectively.

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 D will be explained.

As shown in FIGS. 2 and 4, the mounting board 20
Front extension portion 20a extending forward from one side end of
A control unit mounting plate 50 is provided upright, and a control panel 51 for controlling the operation of the above-mentioned rotation motor 30 is attached to the control unit mounting plate 50, forming a control unit F. are doing. 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 D, and the control section F arranged on the mounting board 20 described above are integrally connected to the mounting board 20.
It is surrounded by an L-shaped cover casing 60 having an outer shape equal to .

Next, the operation part G will be explained. As is most obvious from FIG. , a sheet paper feeding push button 61,
A power lamp 62 consisting of a light emitting diode, etc., a paper replenishment lamp 63 having a warning function in the event of an abnormality such as a paper jam or paper replenishment, and a paper jam lamp 6.
It is constructed by attaching 4 etc.

In place of the paper supply lamp 63, a buzzer or the like may also be installed.

Further, above the sheet paper feeding mechanism section C, a sheet paper roll storage section E is provided, as shown in FIGS. 3, 4, and 5.

And the sheet paper roll storage section E
A sheet paper roll storage box 70 is removably 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, and a sheet paper roll storage box 70 is provided inside the storage box 70 to replace the sheet paper roll storage box 70. It is formed from the attached sheet paper roll R and a pressing roller 71 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 both left and right end walls 70
a, 70b are provided with openings that communicate with openings at both ends of the center axis of the sheet paper roll R, and within the openings are connection plugs 72 that rotatably and removably connect the sheet paper roll R to the left and right end walls 70a, 70b. By moving the connecting plug 72 back and forth in the axial direction, the sheet paper roll R can be easily connected and removed.

Note that the connection plug 72 is connected to the cover casing 6
The left and right side walls 65, 66 on the top of the 0 prevent it from coming off.

Further, the press roller 71 is connected to the sheet paper feeding shaft 2 of the sheet paper feeding mechanism section C described above.
A gear 74 that is in pressure contact with the feed roller 24 attached to the sheet paper feed roller 3 and is fixed to one end of the press roller 71 is meshed with a gear 73 that is fixed to the corresponding end of the sheet paper feed shaft 23.

With this configuration, the sheet paper feeding shaft 2
3 and the feed roller 24 rotate in one direction, the press roller 71 rotates in the opposite direction via gears 73 and 74, and the sheet paper P can be fed out from the sheet paper roll R.

Additionally, an O-ring 71b is attached to the presser roller 71 in a similar manner to match the predetermined position of the feed roller 24.
is installed to effectively prevent the occurrence of idle rotation, slipping, and twisting when sheet paper P is fed out.

Further, as shown in FIG. 5, both ends of the pressing roller 71 are pivoted to the tip of a swinging lever 71a 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 swingable in the vertical direction. It is freely supported.

Further, the press roller 71 is the feed roller 2
A roller made of a material with a heavy specific gravity is used in order to make pressure contact with the roller 4 and reliably feed out the sheet paper P from the sheet paper roll R.

With this configuration, the pressing roller 71 is
Due to its own weight, it comes into pressure contact with the delivery roller 24. In addition, since the pressing roller 71 can swing outward, the sheet paper roll storage box 70 of the sheet paper roll R
Easy to install and remove.

Further, as shown in FIG. 5, there is a space 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.
A slit 75 for taking out sheet paper is formed.

Therefore, sheet paper roll storage box 7
As shown in FIG. 5, the sheet paper P unwound from the sheet paper roll R in 0 is bent outward by the presser roller 71 to uncurl the sheet paper roll R, and then the sheet paper P is unwound by the presser roller 71. Roller 71 and feeding roller 24
After that, the sheet paper is fed out onto the toilet seat main body 11 through the sheet paper removal slit 75.

In addition, the sheet paper roll storage box 70
The cover casing 60 and the cover casing 61 are integrated together to form a functional portion casing H.

Next, to explain sheet paper P,
As shown in FIGS. 5 and 7, the sheet paper P forms a part of the sheet paper roll R, and is used after being cut.

The reason why the sheet paper P is formed from the sheet paper roll R is that the sheet paper P for a large number of people can be stored compactly in the functional part casing H provided at the rear of the toilet seat main body 11, and This is to enable automatic and accurate feeding onto the upper surface of the main body 11.

In addition, as shown in FIGS. 2 and 7, the sheet paper P has cutout perforations in the center thereof at predetermined intervals in the longitudinal direction and having a shape that matches the inner shape of the toilet seat body 11. 80, and an opening communicating with the inside of the flush toilet 10 can be provided along the perforation 80.

However, the perforation 80 is not completely annular, and a non-perforation part 81 is formed between the rear ends of the perforation 80, so when the perforation 80 is cut out, the cut out central part is inside the flush toilet bowl 10. The bottom end will be submerged in standing water.

In addition, the sheet paper P is not completely perforated, and the non-perforated part 81 and the perforated part 8 for cutting out
The reason why 0 is provided is that if the sheet paper P is provided with holes, it will not have any stiffness, and when feeding the sheet paper P onto the toilet seat body 11, it will not bend and it will be almost impossible to form the sheet paper roll R. That's why. In other words, the sheet paper P provided with the perforations 80 and the non-perforated portions 81 has sufficient stiffness, and can be easily subjected to both automatic feeding and roll processing.

Further, the perforations 80 of the sheet paper P can prevent the sheet paper P from being caught in the feeding roller 24 and the press roller 71 as much as possible during feeding.

Further, the perforations 80 for cutting out the sheet paper P can be made into perforations throughout the sheet paper P in a shape that matches the inner shape of the toilet seat main body 11.
It is also possible to provide perforations here and there and make cuts elsewhere.

Further, as shown in FIGS. 2 and 7, the sheet paper P is inserted between the non-perforated part 81 and the tip of the perforated part 80 at regular intervals in the longitudinal direction. On the other hand, a position detection sensor 83 is provided in the center of the cover casing 60 corresponding to the through hole 82.

The position detection sensor 83 detects the through hole 82 when the sheet paper P is fed out a predetermined length from the sheet paper roll R, stops the operation of the sheet paper feeding mechanism section C, and accurately Sheet paper P can be supplied and positioned on the toilet seat body 11.

Note that instead of the through holes 82, desired colored marks may be applied to the sheet paper P, and furthermore, the attachment positions of the through holes 82, etc.
It can be placed not only at the center but also at any desired location.

Further, the above-mentioned supply and positioning of the sheet paper P is performed by counting the number of revolutions of the rotary motor 30 with a desired counter, without using the above-mentioned position detection sensor 83, and operating the control section F based on the counted value. You can also do it by

In addition, in FIG. 2, 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 11 after sitting on the toilet seat body 11, a detection signal is sent. The sheet paper P is instantaneously cut by generating the control unit F and reciprocating the cutting blade 28 in the axial direction.

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 usage conditions and usage environment.

Furthermore, in addition to the seating sensor 84, it is also possible to detect the load at the time of seating with a load cell or the like and operate the control unit F to cut the sheet paper P.

In addition, in FIG. 2, 85 cuts off the power to the rotation motor 30 when the toilet seat body 11 is not detected when the toilet seat body 11 is in a state where it cannot be seated (when the toilet seat body 11 is independent). This is a sensor for stopping the supply of sheet paper P, and detects the toilet seat body 11 only when the toilet seat body 11 is in a seatable state and makes it operable.

Note that instead of the sensor 85, a micro switch, a limit switch, or the like may be used.

Hereinafter, the operation of the automatic sheet paper supplying toilet seat A having the above configuration will be explained.

First, turn on the power with the power switch S and check whether the power lamp 62 is lit.

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. 4).

After checking, push button 61 for sheet paper feeding
Press.

At this point, if there is no paper jam or sheet paper roll R, the paper jam lamp 64 or the paper replenishment lamp 63 of the operation section G lights up.

No paper jams and sheet paper roll R
When there is enough paper jam, or when the paper jam is cleared or the sheet paper roll R is set in the sheet paper roll storage box 70, the control section F operates to drive the rotary motor 30 and to operate the clutch. The mechanism M is driven to select the gear train that communicates with the feed roller 24 and the presser roller 71.

As a result, the forward rotation of the rotary motor 30 is transmitted to the feed roller 24 and the press roller 71 via the gear trains 32, 33, 34, 35, and 36. By the way, the feed roller 24 and the press roller 71 rotate in opposite directions and hold the sheet paper P in a pressed state, so that the sheet paper P is stored in the sheet paper roll R in the sheet paper roll storage box 70. It will be unrolled from

That is, as shown in FIG. 5, the sheet paper P is folded in the reverse winding direction by the press roller 71 to uncurl the sheet paper roll R, and then the sheet paper P is folded between the feeding roller 24 and the press roller 71. After that, the sheet paper is fed out and supplied onto the toilet seat main body 11 through the sheet paper take-out slit 75.

In addition, in this feeding operation, when the sheet paper P is fed out a predetermined length onto the toilet seat body 11, the position detection sensor 83 detects the position detection through hole 82 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/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 main body 11 by an accurate predetermined length. .

Note that the sheet paper P at the stage of being unwound from the sheet paper roll R is curled in the winding direction, but in this embodiment, the curling of the sheet paper P in the winding direction is prevented by the press roller 71. It can be returned and then sent out onto the toilet seat body 11 through the paper removal slit 75.

Therefore, it is possible to reliably prevent a paper jam accident in which the sheet paper P curls in the winding direction and is fed only into the functional part casing H and is not supplied onto the toilet seat body 11.
It is possible to prevent the sheet paper P fed out onto the upper surface of the toilet seat body 11 from being curled near the paper take-out slit 75 without being fed to a predetermined position.

Thereafter, the user cuts off the central part of the sheet paper P along the perforations 80 leaving only the non-perforated part 81, hangs the cut part downward, and puts its tip into the standing water in the flush toilet bowl 10.

As described above, in this embodiment, the sheet paper P can be fed by a predetermined length onto the toilet seat body 11 by a one-touch operation. Moreover, in this state, the sheet paper P is not cut from the sheet paper roll R, so there is no need to worry about it falling off from the flush toilet bowl 10 or to align it.

In addition, due to the operation of the control unit F, even if the sheet paper feeding push button 61 is pressed while the same sheet paper supply is completed, the next sheet paper P
It is designed so that it cannot be dispensed or supplied, and consideration has been given to preventing tampering and determining whether or not it can be used.

Thereafter, the user sits on the sheet paper P on the toilet seat body 11.

When the user sits on the toilet seat body 11 and stands up from the toilet seat body 11 after defecating, the seating sensor 84 detects that the user has left the toilet seat body 11 and operates the control unit F based on the detection signal. At the same time, the clutch mechanism M is operated to rotate the rotary motor 30 in the gear train glass 3.
1, 32, 32a, 39, and 38, and the cutting blade 28 is reciprocated to cut the sheet paper P instantaneously.

In addition, in the above operation, the seating sensor 84
Even if the user stands up from the toilet seat main body 11, the control unit F cannot be operated unless it is sensed for at least 10 consecutive seconds (that is, unless the user is seated for 10 consecutive seconds).

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 feeding or sensing an instantaneous movement of the user other than sitting.

It should be noted that the timing for setting 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 10, and the force of the flushing water entrains the cut-off portion of the sheet paper P along with the flushing water and dirt and allows it to flow out.

In addition, when using a public place such as a theater, after the above series of operations are completed,
The sheet paper P is automatically saved for the next user.
It is also possible to operate the control unit F so as to supply the water onto the toilet seat body 11.

With the configuration and operation described above, this embodiment has the following effects.

Since the sheet paper P can be cut by the cutting blade 28 movable in the width direction perpendicular to the feeding direction of the sheet paper P, the cutting blade 28 has a cutting surface that is at least thicker than the sheet paper P. Since the moving device can be formed from a small piece of lightweight material, the moving device can have a simple configuration, and the cutting mechanism section D can have a compact configuration.

In addition, since the sheet paper P is configured to be cut by the cutting blade 28 movable in the width direction perpendicular to the feeding direction of the sheet paper P,
Since the cutting blade 28 can be formed from a lightweight small piece having a cutting edge surface that is at least thicker than the thickness of the sheet paper P, even if the cutting blade 28 becomes unable to cut, it can be easily and inexpensively replaced. can be replaced, making maintenance extremely easy and inexpensive.

Further, if the cutting blade 28 is made of ceramic or the like, it can be made maintenance-free.

Furthermore, when cutting the sheet paper P,
Since the cutting blade holder supports the cut portion of the sheet paper P to be cut by the cutting blade 28, the sheet paper P can be cut reliably and easily.

By providing the cutting blade guide groove in the cutting blade holder, sheet paper can be cut more reliably.

Furthermore, by forming the cutting blade holder from an elastic material, the durability of the cutting blade and the cutting blade holder can be improved.
