This is related to.

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

In other words, the sheet paper will not be fed out even if the sheet paper feeding button is pressed unless a cutting operation is performed after the sheet paper has been fed out for a predetermined length by the lock mechanism and the control unit. Or, even if a child presses the sheet paper feeding push button more than once due to mischief, the sheet paper will not be fed out for more than one use, which prevents sheet paper from being wasted and prevents it from falling onto the floor, etc. It is possible to prevent the sheet paper from being scattered due to this, and it is possible to keep the installation location clean at all times.

(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 device B equipped with an automatic sheet paper supplying toilet seat A according to the present invention.
It is placed on 0.

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, which will be described later, to press and clamp the drawn end of the sheet paper P and 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 mounting plate 27 is attached to the cutting blade moving shaft 25 and the cutting blade moving guide shaft 26, and the mounting plate 27 is screwed onto the cutting blade moving shaft 25.

Further, a disk-shaped cutting blade 28 is rotatably supported on the upper end of the cutting blade mounting plate 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 plate 27, and the sheet paper P can be cut instantly.

In addition, instead of the above-mentioned structure, the mechanism for moving the cutting blade 28 is configured such that an endless wire or an endless belt is driven by a rotary motor to be able to reciprocate in the left and right width direction, and the cutting blade 28 is moved to 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 performed by rotating rotating shafts 93 and 94 each having a cutting blade 90 and a cutting blade receiving groove 91 as shown in FIGS. 7 and 8. By doing so, 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.

7 shows the rotating shafts 93, 94 in a state where the sheet paper P is fed, and FIG. 8 shows the rotating shafts 93, 94 in a state where the sheet paper P is cut. 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.

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 a gear 31 fixed to the output shaft of the sheet paper through gear trains 32, 33, 34, 35, and 36 to a 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.

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 on the top surface of the operation unit mounting plate 59 disposed inside the cover casing 60;
A power lamp 62 consisting of a light emitting diode, etc., a paper supply 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.

Note that a buzzer or the like may be installed instead of the paper 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. 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 erected on the left and right upper surfaces of the cover casing 60, and a sheet paper roll storage box 70 that is replaceably installed inside the 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 and 66 on the top of the 0 prevent the holder 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, sheet paper roll storage box 70
and the above-mentioned cover casing 60 together form a functional part casing H.

Next, to explain sheet paper P,
As shown in FIGS. 5 and 6, 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 6, 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 6, the sheet paper P is inserted between the non-perforated portion 81 and the tip of the perforation 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

Further, in FIG. 2, reference numeral 84 denotes a seating sensor consisting of a reflective infrared sensor provided at the front of one end of the mounting board 20. After the user sits on the toilet seat main body 11, a certain period of time (for example, 10 seconds) has elapsed. Then, when the user leaves the toilet seat main body 11, a detection signal is generated, the control section F is activated, and the cutting blade 28 is reciprocated in the axial direction to cut the sheet paper P instantly. .

Note that the seating sensor 84 may be used depending on the usage conditions and usage environment.
It is also possible to incorporate it into a single unit or to separate it into a separate body.

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 is a rotary motor that is activated via the control unit F when the detection is removed from the toilet seat body 11 when the toilet seat body 11 is in a state where it cannot be seated (when the toilet seat body 11 is independent). It is an abnormal feeding prevention sensor for stopping the supply of sheet paper P by cutting off the power to the toilet seat body 11.
The toilet seat main body 11 is detected only when the toilet seat body 11 is in a seatable state, and the toilet seat main body 11 is made operable.

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

Further, FIG. 9 shows an example of a control circuit for controlling the operation of the automatic sheet paper supplying toilet seat A.

In FIG. 9, 100 is a sheet paper feeding push button 61, a position detection sensor, a seating sensor 84, and a sheet paper abnormal feeding prevention sensor 85.
101 is an input interface provided between the control section F and the sheet paper feeding mechanism section C, sheet paper cutting mechanism section D, etc. .

A locking mechanism is incorporated in the control section F, and the locking mechanism operates even if the sheet paper feeding button 61 is pressed as long as a cutting operation is not performed after the sheet paper P is fed out for a predetermined length. It is configured so that the sheet paper P is not fed out. Therefore, even if the user presses the sheet paper feeding push button more than once by mistake or by a child, the sheet paper P will only be fed out for one use.

Note that such a locking mechanism can also be a mechanical mechanism.

Hereinafter, the operation of the automatic sheet paper supplying toilet seat A having the above configuration will be explained with reference to the flowchart shown in FIG.

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

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 (101).

At this point, if there is a paper jam or there is no sheet paper roll R, press the paper jam lamp 64 on the operation section G.
Or the paper supply lamp 63 lights up (102)
(103).

No paper jams and sheet paper roll R
When the paper jam is cleared or when the sheet paper roll R is set in the sheet paper roll storage box 70, the toilet seat main body 11 is not in a self-supporting state and the abnormal feeding sensor 85 is activated. When it does not operate, control section F
operates to drive the rotary motor 30 and the clutch mechanism M to move the feed roller 2.
4 and the gear train that connects to 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 pressing roller 71 to uncurl the sheet paper roll R, and then the sheet paper P is folded by the pressing roller 71 to uncurl the sheet paper roll R.
The sheet paper passes between the sheet paper and the pressing roller 71, and then is delivered and supplied onto the toilet seat 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. (104).

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 fed 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 lock mechanism and the control unit F, even if the sheet paper feeding push button 61 is pressed while the same sheet paper P supply is completed, the next sheet paper P will not be fed or fed. This takes into account the prevention of tampering and the determination of whether or not it can be used.

Thereafter, the user sits on the sheet paper P on the toilet seat body 11 (105).

When a person sits on the toilet seat body 11 and stands up from the toilet seat body 11 after defecating (106), the seating sensor 84
detects that the user has left the toilet seat body 11, and based on the detection signal, operates the control unit F to rotate the rotation motor 30 in the reverse direction, and also operates the clutch mechanism M to rotate the rotation motor 30. The motor 30 is connected to the cutting blade moving shaft 25 via the gear train gears 31, 32, 32a, 39, and 38, and the cutting blade 28 is reciprocated to instantly cut the sheet paper P (107).

In the above operation, the seating sensor 84
As mentioned above, for example, the control unit F will not be activated even if the user stands up from the toilet seat main body 11 unless it is sensed for 10 consecutive seconds (that is, unless the user remains seated for 10 consecutive seconds). Preventing it from working.

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 cleaning water entrains the cut-off portion of the sheet paper P together with the cleaning water and dirt and allows it to flow out (108).

In addition, when using public places such as theaters, 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.

That is, the sheet paper P will not be fed out even if the sheet paper feeding button 61 is pressed unless a cutting operation is performed after the sheet paper has been fed out for a predetermined length by the lock mechanism and the control unit F.
Even if the user presses the sheet paper feeding push button 61 more than once by mistake or by a child, the sheet paper P will only be fed for one use, thereby preventing the sheet paper P from being wasted. At the same time, it is possible to prevent the sheet paper P from being scattered due to falling onto the floor, etc., and the installation location can be kept clean at all times.
