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

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

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 automatic sheet paper supply toilet seat A includes a toilet seat main body 11 that is placed on a flush toilet 10 so as to be openable and closable;
It is placed in a fixed state on the rear part of the flush toilet IO, and is formed of a functional part 13 at the front part which pivotally connects the rear part of the toilet seat body 11 with a pivot 12 so as to be rotatable in the vertical direction.

As shown in FIGS. 2 to 5, the functional part 13 is attached to the rear part of the flush toilet 10, and has a rectangular plate bent at a right angle with one end side facing the front of the toilet seat body 11 in plan view.
It is formed of a letter-shaped mounting board 20, a sheet paper feeding mechanism section C, a cutter cutting mechanism section C, a sheet paper roll storage section E, a control section F, and an operation section G mounted on the mounting board 20. ing.

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, 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 (described later) to press and clamp the drawing end of the sheet paper P, feed the sheet paper P from the sheet paper roll storage section E onto the toilet seat main body 11, and supply the sheet paper P. can do.

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. 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.

In addition, in FIGS. 4 and 5, 25 is a support plate 22,
A cutting blade movement shaft 25 is horizontally suspended between the front ends of the lower portions of the cutting blades 22 and is formed from a rod. Directly above the movement shaft 25, a cutting blade movement guide shaft 26 formed from a solid rod is provided.

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

In addition, FIG. 7 shows the rotating shafts 93.94 in the state of feeding the sheet paper P, FIG. 8 shows the rotating shafts 93.94 in the state of cutting the sheet paper P, and 95.96 A holding roller and a feeding roller are shown, 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. 2 and 4, 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 rotary motor 30 is driven by the operation of the clutch mechanism M, and the feeding operation of the sheet paper P and the cutting operation of the sheet paper P are performed by driving the rotary motor 30 in forward and reverse directions. It can be done sequentially.

Further, the feeding operation and 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 will be explained.

As shown in FIGS. 2 and 4, 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 mounting board 20 described above 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. 4, 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 639, 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 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.

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. , a sheet paper roll R that is replaceably installed 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.

Note that the connection plug 72 is prevented from coming off by left and right side 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. 5, both ends of the pressing roller 71 have their base ends placed vertically at the lower front surface of the L-shaped opening/closing lid 70c for sheet paper roll exchange that forms the front wall of the sheet paper roll storage box 70. It is rotatably supported at the tip of a swing lever 71a, which is swingably supported at the tip of the swing lever 71a.

Further, the pressing roller 71 is in pressure contact with the feeding roller 24 and is made of a material with a low 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.

Moreover, since the press roller 71 can swing outward, it becomes easy to attach and detach the sheet paper roll R to and from the sheet paper roll storage box 70.

Further, as shown in FIG. 5, 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 sheet paper roll replacement lid 70c of the sheet paper roll storage box 70. ing.

Therefore, the sheet paper P unwound from the sheet paper roll R in the sheet paper roll storage box 70 is once moved to the presser roller
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.

Next, the sheet paper P will be explained. 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 body 1. This is to enable the toilet seat body 11 to be automatically and accurately extended onto the upper surface.

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 both ends of the rear part.
When the perforation 80 is cut out, the cut out central portion will hang down into the flush toilet bowl 10, and its lower end will be submerged in standing water.

In addition, the reason why the sheet paper P is not completely perforated but is provided with the non-perforated part 81 and the cutout perforation 80 is because if the sheet paper P is made perforated, there will be no stiffness, and the sheet paper P will be placed on the toilet seat body 11. When feeding, it may be bent or
This is because it is almost impossible to form a sheet paper roll R. 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 perforation 80 of the sheet paper P allows the sheet paper P to be used by the feeding roller 24 or the presser roller 7 during feeding.
1 can be prevented as much as possible.

Moreover, the perforations 80 for cutting the sheet paper P can be made into perforations throughout the sheet paper P in a shape that matches the inside shape of the toilet seat main body 11, and perforations can be provided here and there. Others can be cut.

Furthermore, as shown in FIG. 2 and FIG. 6, the sheet paper P has non-perforated portions 81 at regular intervals in the longitudinal direction.
A position detection through hole 82 is provided between the perforation 80 and the tip of the perforation 80, and a position detection sensor 83 is provided at 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.

In addition, instead of such a through hole 82, a desired colored mark may be applied to the sheet paper P, and furthermore, the attachment position of the through hole 82 etc. may be not only in the center of the sheet paper P but also at any arbitrary location. be able to.

Further, the above-mentioned supply and positioning of the sheet paper P can be performed using the rotary motor 3 without using the above-mentioned position detection sensor 83.
It is also possible to count the number of rotations at 0 using a desired counter and operate the control unit F based on the counted value.

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 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. .

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

Furthermore, in addition to the seating sensor 84, the load at the time of seating is detected by a load cell, etc., and the control unit F is actuated to control the sheet paper P.
It is also possible to cut the

In addition, in FIG. 2, 85 is a state in which the toilet seat main body 11 is not seated (when the toilet seat main body 11 is self-supporting), and when the detection is removed from the toilet seat main body 11, the control section F controls the
This is an abnormal feeding prevention sensor that cuts off the power to the rotation motor 30 and stops the supply of sheet paper P, and only when the toilet seat body 11 is in a state where it can be seated.
1 is detected to enable operation.

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

Furthermore, as shown in FIG. 5, in this embodiment, the sheet vapor roll replacement opening/closing lid 70c, which forms a part of the functional part casing I and can be opened and closed around the pivot 70d, is linked with the opening operation. The present invention is also characterized in that it includes a safety device SD that stops power supply to the sheet paper feeding mechanism section C, sheet paper cutting mechanism section, control section F, etc. from the power supply PS, which will be described later.

In addition, in FIG. 5, the safety device SD is shown as a normally closed contact microswitch provided on the rear wall of the sheet paper roll storage box 70, and is linked to the opening operation of the sheet paper roll replacement opening/closing lid 70c. It becomes an open contact and the power supply can be cut off.

That is, in FIG. 9 showing an example of a control circuit and a power supply circuit for controlling the operation of the automatic sheet paper supplying toilet seat A, 1
10 is an input interface interposed between the control section F and the sheet paper feeding push button 61, position detection sensor 83, seating sensor 84, sheet paper abnormal feeding prevention sensor 85, etc.; This is an output interface interposed between the sheet paper feeding mechanism section C, the sheet paper cutting mechanism section, etc.

Then, the above-mentioned sheet paper feeding push button 61
- Position detection sensor 83, seating sensor 84, sheet paper abnormality feeding prevention sensor 85, etc., from the power source ps to the control section F, sheet paper feeding mechanism section C, sheet paper cutting mechanism section D1, human output interface t1o, oi, etc. Power is supplied via a power supply line 112.

Therefore, a safety device SO is interposed in the middle of the current supply line 112, and the safety device SD is activated by the opening operation of the above-mentioned sheet vapor roll replacement opening/closing lid 70c, and the sheet paper feeding push button 61, power to position detection sensor 83, seating sensor 84, sheet paper abnormality feeding prevention sensor 85, etc., control section F, sheet paper feeding mechanism section C, sheet paper cutting mechanism section D, input/output interface 110, 111, etc. supply can be stopped.

Therefore, when replacing the sheet paper roll R,
It is possible to reliably prevent accidents such as fingers being accidentally caught in the sheet paper feeding mechanism section C or fingers being cut off by the sheet paper cutting mechanism section, and the safety of the sheet paper roll R replacement work is significantly improved. can be improved.

In addition, in the embodiment shown in FIG. 5, as the safety device SO,
Although a microswitch is used, other contact type sensors, non-contact type sensors, etc. can also be used.

Below, sheet paper automatic supply toilet seat A having the above configuration
The operation will be explained with reference to the flowchart shown in FIG. 1O.

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

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 R is stored in the sheet paper roll storage box 70.
When the toilet bowl body 11 is not in a self-supporting state and the irregular character feeding sensor 85 does not operate, the control section F operates to drive the rotation motor 30 and the clutch mechanism M. by driving the feeding roller 24
and select 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, 36. By the way, the feeding roller 24 and the pressing roller 71 rotate in opposite directions and hold the sheet paper P in a pressed state, so that the sheet paper P is held 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 once bent in the reverse winding direction by the press roller 71 to uncurl the sheet paper roll R, and then passed between the feeding roller 24 and the press roller 71. Thereafter, the sheet paper is delivered 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 ll, 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 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 11 by an accurate predetermined length (104 ).

Note that, although the sheet paper P is curled in the winding direction at the stage of being unwound from the sheet paper roll R, in this embodiment, the curling of the sheet paper P in the winding direction is reversed by the pressing roller 71. After that, it can be sent out onto the toilet seat main 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, and the upper surface of the toilet seat body 11 It is possible to prevent the sheet paper P fed out from being curled near the paper take-out slit 75 without being fed to a predetermined position.

After that, the user cuts off the center part of the sheet paper P along the perforations 80 leaving only the non-perforated part 81,
Let the cut-off part hang down and attach the tip to the flush toilet 10.
Attach it to the pooled water inside.

As described above, in this embodiment, the sheet paper P can be supplied to a predetermined length onto the toilet seat main body 11 by drying wonton chips. 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 miscommunication from the flush toilet 10 or to perform positioning.

In addition, by the operation of the lock mechanism (not shown) and the control unit F, even if the sheet paper feeding push button 61 is pressed while the same sheet paper P has been completely fed, the next sheet paper P will not be fed or fed. The system is designed to prevent tampering and to determine whether or not it can be used.

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

When the user sits on the toilet seat main body 11 and stands up from the toilet seat main body 11 after urinating (106), the seating sensor 84 detects that the user has left the toilet seat main body 1, and based on the detection signal, the control unit F is activated to reversely rotate the rotary motor 30, and at the same time, the clutch mechanism M is activated to rotate the rotary motor 30 in the reverse direction.
0 to gear train gear 31.32.32a, 39.38
The cutting blade moving shaft 25 is connected to the cutting blade moving shaft 25 through the cutting blade 28, and the cutting blade 28 is reciprocated to instantly cut the sheet paper P (1
07).

In the above operation, as described above, unless the seating sensor 84 continuously senses for 10 seconds (
(i.e., unless the user remains seated for 10 consecutive seconds)
, the control section F cannot be operated even if the user stands up from the toilet seat main body 11.

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.

After that, the cleaning device is driven to clean the inside of the flush toilet bowl 10,
Due to the force of the washing water, the cut-off portion of the sheet paper P can be drawn in and flowed out together with the washing water and dirt (10B).

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

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

That is, by the safety device SD, the sheet paper roll R
Even if an operation button, etc. is pressed by mistake when replacing the paper, the safety device SD prevents the various operation buttons, etc. on the sheet paper feeding mechanism section C, sheet paper cutting mechanism section, and the control section F and operation section G that control them from being pressed. Since the electricity can be cut off, it is possible to prevent accidents such as accidentally getting your finger caught in the sheet paper feeding mechanism C or having your finger cut off by the sheet paper cutting mechanism when replacing the sheet paper roll R. This can significantly improve the safety of sheet paper roll replacement work.

In the above embodiment, the sheet paper P is cut by the disk-shaped sharp cutting blade 28, but the sheet paper P is cut in a direction perpendicular to the feeding direction at a certain interval in the feeding direction. It is also possible to provide a perforation, clamp both sides of the perforation, apply a pressing force to the perforation from above or below with a rounded pressing blade, etc., and cut the material by breaking it.
