In addition, the cutting of the sheet paper P
Since the cutting is performed by applying the tension and the pressing force, the sheet paper cutting portion 61 of the swing plate 51 or the cutting blade 61a does not need to be formed of a sharp metal or the like. It can also be formed of a corrosive and wear-resistant synthetic resin or the like.

Therefore, even during long-term use, frequent replacement of the swing plate 51 due to corrosion or wear can be prevented, and maintenance can be improved.

Further, as shown in FIG. 5, if the cutting blade 61a is formed in a mountain shape, the cutting performance can be improved.

Similarly, the movable plate 51 can also be formed of a corrosion-resistant and wear-resistant synthetic resin, ceramics, or the like.

Next, the configuration of the sheet paper roll storage section E disposed on the casing body 16 including the sheet paper feeding machine groove C and the sheet paper cutting machine groove D will be described.

4 and 5, reference numerals 80 and 81 denote support rods fitted into the bosses 37 and 38 of the suspension frame 33 having a spring 82 therein. The both ends of a hollow roll core 83 having the outer periphery mounted thereon are removably inserted and erected.

Reference numeral 84 denotes a sheet paper roll protection cover disposed on the casing main body 16 so as to surround the sheet paper roll R. It is detachably engaged and supported on a cover receiving plate 86 erected between the lower front portions of the arms 34 and 35, and the lower rear end is provided at the rear wall of the casing body 16.
It is engaged and supported by the upper end of an extended rear wall 87 extending above the upper part of the upper part 21.

As shown in FIGS. 5 and 11, the both ends of the sheet paper roll protective cover 84 are fitted with grooves 88, 8 recessed along the inner edge of the sheet paper roll mounting wall 23.
9 is engaged.

With this configuration, when the sheet paper P is rewound,
Alternatively, it is possible to prevent the suspension support frame 33 from swinging due to vibration or the like generated when the movable plate 50 comes into contact with the swing plate 51.

If the sheet paper P is entangled in the sheet paper delivery path 8 or the like, remove the sheet paper roll protective cover 84 as shown in FIG. 11, and then swing the suspension frame 33 forward. Thus, the entangled sheet paper P can be easily taken out.

Next, the sheet paper P used in the present embodiment will be described. As shown in FIGS. 4 and 5, the sheet paper P forms a part of the sheet paper roll R, and is cut and used. Things.

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 compactly stored in the functional section 14 provided behind the toilet seat body 11, This is in order to be able to automatically and accurately feed out to the upper surface of the eleventh embodiment.

As shown in FIGS. 3 and 12, the sheet paper P is provided with straight cutting perforations 90 in the width direction at regular intervals in the longitudinal direction or the feeding direction.
Then, the sheet paper P is cut.

Further, the sheet paper P is provided with a cutout perforation 91 having a shape adapted to the inner shape of the toilet seat main body 11 at a central portion between the cutout perforations 90, 90, and along the cutout perforation 91. By cutting out the sheet paper P, an opening communicating with the inside of the flush toilet 10 can be provided.

However, the cutout perforation 91 is not completely annular, and a non-perforated portion 92 is formed between both ends thereof. Therefore, when the perforation 91 is cut off, the cut-out central portion is flushed with a flush toilet. It hangs down in 10 and its lower end pools and gets soaked in water.

Further, the sheet paper P is not completely perforated and the perforation-free portion 92 and the cutout perforation 91 are provided.
If perforated, the waist will be lost and sheet paper P
This is because it is almost impossible to bend or form the sheet paper roll R when supplying the sheet onto the toilet seat body 11. That is, the sheet paper P provided with the cutout perforations 91 and the non-perforated portions 92 has sufficient stiffness, and both automatic feeding and roll processing can be easily performed.

Also, the perforation 91 for cutting out the sheet paper P
At the time of feeding, it is possible to prevent the sheet paper P from getting caught in the feeding roller 31 and the pressing roller 32 and jamming as much as possible.

Also, the perforation 91 for cutting out the sheet paper P
Perforations may be formed entirely in the shape adapted to the inner shape of the toilet seat body 11, or perforations may be provided in some places, and others may be cut.

Further, as shown in FIGS. 3 and 12, the sheet paper P is disposed at regular intervals in the longitudinal direction at a non-perforated portion 92.
A hole 93 for position detection is provided between the front end of the inclined ceiling wall 22 of the casing body 16 corresponding to the hole 93, and a light-emitting element and a light-receiving element. Are provided.

The position detection sensor 94 detects the through hole 95 when the sheet paper P is fed out from the sheet paper roll R by a predetermined length, stops the operation of the sheet paper feeding mechanism C, and accurately detects the through hole 95. The sheet paper P can be supplied and positioned on the toilet seat main body 11.

In place of the through-hole 95, a desired coloring mark may be provided on the sheet paper P. Further, the mounting position of the through-hole 95 and the like is not limited to the central portion of the sheet paper P, but may be any position. be able to.

Further, the supply and positioning of the sheet paper P are performed without using the position detecting sensor 94, and the rotation motor 40 is used.
Can be counted by a desired counter, and the control unit F is operated based on the counted value.

In FIG. 1, reference numeral 96 denotes a seating detecting means such as a reflection-type infrared sensor provided on the inner surface of the one side extension 25 of the casing main body 16, and after a user sits on the toilet seat main body 11, a fixed When a time (for example, 10 seconds) elapses and the user separates from the toilet seat main body 11, a detection signal is generated, the control unit F is operated, the rotation motor 75 is driven, and the clamp of the sheet paper P is released. At the same time, the movable plate 50 and the swinging plate 57 can be moved from the position shown in FIG. 9 to the position shown in FIG. 10 so as to block the infiltration of the wastewater into the sheet paper delivery path 8.

It should be noted that the seating detection means 96 can be incorporated into the sheet paper automatic supply toilet seat A as an integral unit or separated from the seat sheet automatic supplying toilet unit A depending on the operating conditions and operating environment.

Further, the seating detecting means 96 may use a micro switch, a limit switch, or the like in addition to the infrared sensor or the like, or may detect a load at the time of seating with a load cell or the like to control the F.
Can also be activated.

In FIG. 1, reference numeral 97 denotes a rotation motor via the controller F when 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 self-standing). An abnormal feeding prevention sensor for stopping the supply of the sheet paper P by cutting off the current to the toilet seat body 40.
Only when the seat is in a seatable state, the toilet seat main body 11 is detected to be in an operable state.

Note that, as the abnormal feeding prevention sensor 97, a micro switch, a limit switch, or the like can be used instead of a normal sensor.

Next, the configuration of the sheet paper feeding mechanism C, the sheet paper cutting mechanism D, and the control unit F that controls the operation of various sensors and detection means will be described.

As shown in FIG. 5, a control unit mounting plate 100 is provided upright in a compartment 23b formed on one side of the casing body 16, and the control unit mounting plate 100 has the above-described rotating motor. 40,75
A control panel 101 for controlling the operation and the like is mounted, and forms a control unit F. The control panel 101
The transformer 102 is also integrally mounted.

Next, the operation unit G will be described. As is clear from FIGS. 1 and 3, the operation unit G is provided on the upper surface of the one side extension 25 of the casing main body 16 with a sheet paper feeding button 103 and a light emission button. Power lamp 104 consisting of a diode etc.

Note that a buzzer or the like can be attached instead of the paper supply lamp 105 or the like.

FIG. 13 shows an example of a control circuit for controlling the operation of the sheet paper automatic supply toilet seat A.

As shown in FIG. 13, the control unit F includes a microprocessor MPU, input / output interfaces 110 and 111, and a memory M storing a sheet paper feeding / cutting sequence program described below.

The input interface 110 is interposed between the sheet paper feeding push button 103, the position detecting sensor means 94, the seating detecting means 96, and the microprocessor MPU, and the output interface 111 is connected to the microprocessor MPU. It is interposed between the sheet paper feeding mechanism C and the sheet paper cutting mechanism D.

The control unit F is provided with a first timer T1, and the timer T1 is activated when the sheet paper feeding button 103 is pressed for a predetermined time, for example, 5 seconds, and a sheet paper cutting mechanism unit. This is to form reset means that can reset D to an initial state.
That is, the sheet paper P is released from the clamp, and the sheet paper outlet 85 can be closed.

Therefore, when the sheet paper fed out onto the toilet seat main body 11 is twisted or wet by the resetting means constituting the pinching release means, the sheet paper cutting mechanism D is moved to the initial state as described later. And the sheet paper P can be easily taken out of the toilet seat body and discarded in the toilet 10.

In addition, the other configuration in the illustrated embodiment will be described. In FIG. 5, 120 and 121 are through-holes provided in the outer wall 23a and the side wall 18, respectively.
The rotation motors 40 and 75 can be cooled.

Hereinafter, the operation of the sheet paper automatic supply toilet seat A having the above configuration will be described with reference to the flowcharts shown in FIGS. 14 (A) and 14 (B).

In the non-energized state, the movable plate 50 in the casing main body 16 closes the sheet paper outlet 85 at one end as shown in FIG. 8 is prevented.

In this state, when the flush toilet 10 is used, when the power switch S provided on the back surface of the casing body 16 is turned on as shown in FIG. 5 (150), the power lamp 104 is turned on (151).

Then, press the sheet paper feed button 103 (1
52), the control unit F generates a drive signal based on the sheet paper feeding / cutting sequence program read from the memory M, and the rotation motor 75 and the sheet paper feeding mechanism of the sheet paper cutting mechanism D are driven by the driving signal. The rotation motor 40 of the section C operates sequentially. Then, the movable plate 50 rotates counterclockwise by the clockwise rotation of the disc cam 71 driven by the rotation motor 75, and changes from the posture shown in FIG. 10 to the posture shown in FIG. . That is, the movable plate
The sheet paper delivery path 8 communicating with the sheet paper delivery port 85 is formed on the top 50 (157).

Thereafter, the rotation motor 40 is driven to feed out the sheet paper P from the sheet paper roll R (15).
8).

However, when the sheet paper roll protective cover 84 is not mounted on the casing body 16, the cover safety switch (not shown) is in the OFF state. Under the control of the unit F, the drive signal from the control unit F is not sent to the rotary motor 40 (153), and the safety of operation can be ensured.

In addition, the user places the sheet paper P on the toilet seat body 11.
It is not preferable to feed the sheet paper P onto the toilet seat main body 11 even when the user is seated in a state in which the seat paper P has not been fed out. We do not send to 40 (15
Four).

In addition, since it is not preferable to feed the sheet paper P to the toilet seat body 11 when the toilet seat body 11 is standing, the abnormal feeding prevention sensor 97 detects that the toilet seat body 11 is in the upright state, and the control unit F The drive signal is not sent to the rotation motor 40 (155).

Further, when the presence of the sheet paper P in the sheet paper delivery path 8 in the casing body 16 is detected by the position detecting sensor 94 which also serves as a paper detection disposed in the casing body 16, the feeding of the sheet paper P is performed by the casing. Since the sheet paper P is entangled in the main body 16, the detection signal is used to prevent the control unit F from sending a drive signal to the rotary motor 40 (156).

If there is no abnormal state, as described above, a drive signal is sent from the control unit F to the rotation motor 40 to drive the rotation motor 40 (158). It will be paid out.

When the rotation motor 40 starts driving, the second timer
T2 (FIG. 13) is activated (159). Then, the sheet paper P is fed out onto the toilet seat main body 11, and thereafter, the position detection sensor 94 normally detects the sheet paper P within the timer set time t1, and sets the sheet paper P within the timer set time t2. When the through hole 93 provided in P is detected (159cY), the rotating motor 40 stops in a state where the set length sheet paper P is fed out onto the toilet seat body 11 (160).
At this point, the cutting perforation 90 located at the rear end of the sheet paper P is located substantially directly below the swing paper 51 and the sheet paper cutting blade 61a.

However, when the detection of the position detection sensor 94 is abnormal, that is, when the position detection sensor 94
If 94 does not detect sheet paper P (159aN),
The sheet motor 40 is turned off and the paper trouble lamp 106 is turned on (161).

Further, even if the sheet paper P is detected within the timer set time t1, the position detecting sensor 94 is earlier than the next timer set time t2 (counting from the start of driving of the rotating motor 40).
(159bY), the rotary motor 40
Is turned off, and the paper supply lamp 105 is turned on (16
2).

Further, when the through hole 93 is not detected within the timer set time t2 (159cN), the turning motor 40 is turned off and the paper trouble lamp 106 is turned on (163).

Then, the rotation motor 75 is restarted by the drive signal from the control unit F, and as shown in FIGS. 7 and 8, the sheet paper P is clamped between the sheet paper pressing pieces 56 and 64 and the feeding roller 31 is rotated. When the rotary motor 75 continues to be driven by a continuous drive signal from the control unit F, the tension in the feeding direction is applied to the portion of the sheet paper P located between the two clamp portions. Will be added (164).

Further, when the rotation motor 75 is driven by a drive signal from the control unit F, the sheet paper cutting blade 61a of the sheet paper cutting unit 61 of the swing plate 51 causes the sheet paper P to cut the sheet paper P as shown in FIG. Press along eye 90,
The sheet paper P is reliably broken, that is, cut by the pressing force and the tension in the feeding direction (16).
Five).

Thus, the rear end of the cut sheet paper P is securely clamped by the sheet paper pressing pieces 56 and 64 (165).

Thereafter, when the user sits on the toilet seat body 11 (16
9), the seating detection means 96 detects that the user is seated (170),
Based on the detection output, the control unit F performs control so as not to send a drive signal to the rotary motor 40 even if the sheet paper feeding button 103 is pressed thereafter, as long as the seating detection unit 96 detects the button (171). .

Therefore, even if the user presses the sheet paper feeding button 103 by mistake or mischief in a seated state, the sheet paper P is not fed out, so that an accident such as entanglement of the sheet paper P in the casing main body 16 is ensured. Can be prevented.

Then, when the user separates from the toilet seat body 11 after stool (172), the seating detection means 96 is turned off (173), and based on the OFF signal, the control unit F sends a drive signal to the rotating motor 75 again. To rotate the rotation motor 75. As a result, the movable plate 50 and the swing plate 51 assume the state shown in FIG.

That is, while the clamp of the sheet paper P is released, the movable plate 50 is positioned in the casing main body 16 such that the movable plate 50 can reliably prevent sewage from entering the sheet paper delivery path 8 through the sheet paper delivery port 85. Can be taken (174) (175).

After that, the cleaning device is driven to clean the inside of the flush toilet 10,
By the water force of the cleaning water, the cutoff portion of the sheet paper P can be drawn in and flown out together with the cleaning water and the dirt.

In the above step, the sheet paper P is cut and cooperated by the cooperation of the movable plate 50 and the swing plate 51.
If someone forcibly pulls out the sheet paper P after being held (165) and before sitting (169) (16
6) Alternatively, if the sheet paper P fed out onto the toilet seat body 11 is wet, and the sheet paper feeding button 103 is kept pressed for a predetermined time (about 5 seconds) to remove it, (167) If the user does not sit on the toilet seat body 11 within a predetermined time for some reason (16
8) In order to discard the sheet paper P as unused by the respective reset means, regardless of the seating detection means 96, the control unit F sends a drive signal to the rotary motor 75, and the movable plate 50 and the swing The state shown in FIG. 10 is applied to the plate 51 to release the clamp of the sheet paper P and close the sheet paper outlet 85 (174) (175).

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

That is, in the present invention, the sheet paper cutting mechanism D
Is controlled by the control unit F so as to securely clamp the rear end even after cutting the sheet paper P, so that even when the user slightly moves his body during stool, the sheet paper P There is no risk of falling from the toilet seat body 11, and the toilet can be performed comfortably.

Further, in the present invention, when the sheet paper P fed out onto the toilet seat main body 11 is twisted or wet, the sheet paper cutting mechanism D is kept pressed for a predetermined time by pressing the sheet paper feeding button 103, Since it can be returned to the initial state, the sheet paper P is easily taken out from the toilet seat body 11 by releasing the clamp, etc.
It can be discarded in the toilet 10 and the next sheet paper P
Can be quickly dispensed onto the toilet seat body 11 again.
