As long as the rotation motor 40 is in a stopped state, not only the rotation of the feed roller 31 but also the press roller 320 can be reliably prevented from rotating, and loosening of the clamping force due to slipping of the press roller 32 etc. can be reliably prevented. can.

Next, the configuration of the sheet paper cutting mechanism will be explained.

In this embodiment, the sheet paper cutting mechanism is as follows:
As shown in FIGS. 4 and 5, a plate insertion space 22a provided in the front part of the inclined ceiling wall 22 of the casing body 16
A movable plate 50 is swingably disposed within the movable plate 50, and a lower end front portion of the swing arm 34, 35 of the suspension support frame 33, which is disposed above the movable plate 50, is swingably installed. It is composed of a swing plate 51.

First, to explain the configuration of the movable plate 50, as shown in FIGS. 4 and 5, the movable plate 50 is formed from a long and wide rectangular flat plate extending in the left-right direction, and has pivots at both ends. 52 and 53 are provided in a protruding manner, and the same pivots 52 and 53 are rotatably supported on the left and right side walls 18 and 19 of the casing body 16, respectively.

Further, reference numerals 54 and 55 are biasing springs attached to the pivot shafts 52 and 53 in order to keep a guide roller 70, which will be described later, in constant contact with the disc cam 71.

Further, 56 is a sheet paper pressing piece made of an elastic material, which is provided at the rear of the upper surface 50a of the movable plate 50, and clamps the sheet paper P in cooperation with a sheet paper pressing piece 64 of the swinging plate 51, which will be described later. It is something.

When feeding out the sheet paper P onto the toilet seat main body 11, as shown in FIG. 8 can be formed.

Further, as will be described later, when cutting the sheet paper P, the movable plate 50 can be rotated around the pivot shafts 52 and 53 to take the rotational positions shown in FIGS. 7 to 9. Furthermore, when the toilet seat is not in use, the movable plate 50 can be made to take the rotational position shown in FIG. 10.

Next, the configuration of the swing plate 51 which cooperates with the movable plate 50 to cut the sheet paper P will be explained.

As shown in FIG. 4, the swing plate 51 is formed of a thick sheet paper pressing part 60 and a thin sheet paper cutting part 61, and has a U-shaped cross section opening downward. have.

The swinging plate 51 has its sheet paper pressing portion 6
Pivot shafts 62 and 63 are protruded from both ends of the upper part of 0, and both pivots 62 and 63 are connected to the left and right swing arms 34°3 of the suspension support frame 33.
It is rotatably supported at the front lower end of 5.

Furthermore, the swinging plate 51 has a sheet paper pressing piece 64 made of an elastic material attached to the lower end of its sheet paper pressing part 60, and the pressing piece 64 and the movable plate 50
The sheet paper P can be clamped by the sheet paper pressing piece 56 without causing slippage.

In addition, return springs 6 are attached to the pivots 62 and 63, respectively.
5.66 is attached, and the spring 65.66 always urges the rocking plate 51 to rotate in the counterclockwise direction in FIG.
．． In cooperation with the stoppers 67 and 68 protruding from the inner surface of the sheet paper 24, the swing plate is moved so that the sheet paper cutting section 61 is in the standby position shown in FIG. 51 can be held.

Next, the drive mechanism for the sheet paper cutting mechanism consisting of the movable plate 50 and the swinging brake 51 is as follows:
Various types of configurations are possible, but in this embodiment, the configuration is as shown in FIGS. 4 to 6.

That is, the movable plate 50 has a pivot 52 at its lower part.
．． A guide roller 70 is installed at a position eccentrically rearward from 53. Below the guide roller 70, a disc cam 7 is rotatably abutted against the guide roller 70 and moves the guide roller 70 up and down by rotation.
A rotary shaft 7 to which the disc cam 71 is fixed.
2 has both ends attached to the rectangular mounting plate 1 of the casing body 16.
It is rotatably supported by a pair of bearing stands 73 erected on 7. Further, one side extension portion of the rotating shaft 72 is connected to the left side wall 18.
through the sheet paper roll mounting wall 23 and the outer wall 2
It extends into a compartment 23b formed between 3a, and the extension is operatively connected to a rotation motor 75 via a speed reduction device 74.

With this configuration, when the rotation motor 75 is driven, the rotation shaft 72 rotates, and the disc cam 71 that is integral with the rotation shaft 72 also rotates about the axis of the rotation shaft 72. Since the center of the disc cam 71 is eccentric from the axis of the rotating shaft 72, the peripheral surface of the disc cam 71 draws a cam locus with an irregularly shaped opening, and the guide roller has a peripheral surface that comes into contact with the peripheral surface of the disc cam 71. 70 moves up and down, and this up and down movement allows the movable plate 50 to swing around the pivot shafts 52 and 53, and in conjunction with the swinging of the movable plate 50, the swing plate 51 also swings. Thus, the sheet paper P can be effectively cut in the manner described below.

First, in FIG. 4, the sheet paper P is fed onto the toilet seat main body 11 through the sheet paper feed path 8 by the rotation of the feed roller 31 and press roller 32 driven by the sheet paper feed mechanism section C described above. In addition, at this time, the cutting perforation 90 (see FIG. 3) provided in the sheet paper P is fed out so that it is located approximately directly below the cutting blade 61a of the sheet paper cutting section 61 of the swing play 1-51. become.

Next, when the rotary motor 75 is driven to rotate the disk cam 71 clockwise, the movable plate 50 rotates counterclockwise about the pivot shafts 52 and 53 via the guide roller 70, as shown in FIG. As shown, the sheet paper pressing piece 56 is connected to the sheet paper pressing piece 6 of the swing plate 51.
4 and clamp the sheet paper P. and,
The portion of the sheet paper P located between the clamp portion and the clamp portion that is in contact with the feed roller 31 and the press roller 32 is pressed and bent upward by the rear end of the movable plate 50 to apply tension to the sheet paper P.

As described above, the feeding roller 31 and the pressing roller 32 are engaged with each other by the transmission gear 42.43, and the movable plate 50 and the swinging plate 51 are connected to the sheet paper through the sheet paper pressing piece 56.64. Since P is clamped, slippage at the clamped portion can be reliably prevented.

After that, if the disc cam 71 is further rotated clockwise,
The movable plate 50 further rotates counterclockwise as shown in FIG. 8, while the movable plate 50 causes the swing plate 51 to rotate clockwise. Therefore, the cutting blade 61a provided at the tip of the sheet paper cutting section 61 of the swing plate 51 presses the sheet paper P downward while further applying tension.

Further, as shown in FIG. 9, if the disc cam 71 is rotated clockwise, the movable plate 50 is further rotated counterclockwise, and the swing plate 51 is also rotated clockwise. The cutting blade 61a of the sheet paper cutting section 61 of the swing plate 51 further presses the sheet paper P downward to apply tension, and as a result, the sheet paper P is cut from the perforation 80.

Then, the sheet paper P after cutting is pressed by the pressing piece 56.6.
4 continues to be clamped.

Then, when the user leaves the toilet seat main body 11 after using the toilet,
Further, the disc cam 71 rotates clockwise, and the movable plate 50 rotates clockwise this time to release the clamp of the sheet paper P and take the position shown in FIG. Inflow into the channel 8 can be effectively prevented.

Note that since the sheet paper P is cut by applying tension and pressing force to the sheet paper P, the sheet paper cutting portion 61 of the swing plate 51 or its cutting blade 61a is formed of a sharp metal or the like. It is not necessary to do so, and it can also be formed of rounded ceramics, corrosion-resistant and wear-resistant synthetic resin, or the like.

Therefore, even when used for a long period of time, 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, the cutting blade 61a can be formed into a chevron shape to improve cutting performance.

Similarly, the movable plate 51 can also be made of 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 mechanism section C and the sheet paper cutting mechanism section will be explained.

4 and 5, reference numeral 80.81 is a support rod fitted into the boss portion 37.38 of the suspension support frame 33, which is equipped with a spring 82 inside. Both ends of a hollow roll core 83, which has a roll core 83 attached to its outer circumferential surface, are removably inserted and constructed.

Further, 84 is a sheet paper roll protective cover disposed on the casing main body 16 in a state surrounding the sheet paper roll R, and its front lower end is provided at the sheet paper outlet 85 to prevent the swinging of the hanging support frame 33. Arm 34.
35 is removably engaged with and supported on a stop plate 86, and its rear lower end is connected to the upper end of an extended rear wall 87 extending above the rear wall 21 of the casing body 16. Engaged and supported.

Further, both ends of the sheet paper roll protection cover 84 engage with fitting grooves 88 and 89 recessed along the inner edge of the sheet paper roll mounting wall 23, as shown in FIGS. 5 and 11. It matches.

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

In addition, if the sheet paper P becomes entangled in the sheet paper delivery path 8, etc., remove the sheet paper roll protection cover 84 as shown in FIG.
By swinging the paper forward, the entangled sheet paper P can be easily removed.

Next, the sheet paper P used in this example will be explained. As shown in FIGS. 4 and 5, the sheet paper P forms a part of the sheet paper roll R, and is used after being cut. It is something.

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 section 14 provided at the rear of the toilet seat body 11. This is to enable automatic and accurate feeding onto the upper surface of 11.

Further, as shown in FIGS. 3 and 12, the sheet paper P has linear cutting perforations 90 in the width direction at regular intervals in the longitudinal direction or the feeding direction, and Then, the sheet paper P is cut.

Also, the sheet paper P has perforations for cutting at 90°90
A cutout perforation 91 with a shape that matches the inner shape of the toilet seat body 11 is provided in the center between the toilet seat body 11 and the interior of the flush toilet 10 by cutting out the sheet paper P along the cutout perforation 91. A communicating opening may be provided.

However, the cutout perforation 91 is not completely annular, and a non-perforation part 92 is formed between both ends of the rear part, so when the perforation 91 is cut out, the cut out center part is a flush toilet. 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 has the non-perforated part 92 and the cutout perforation 91 is that when the sheet paper P is made perforated, the waist becomes narrower (the seat paper P becomes When feeding it to the top, it may bend 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 cutout perforations 91 and the non-perforated portions 92 has sufficient stiffness and can be easily fed automatically and rolled.

In addition, the perforation 91 for cutting out the sheet paper P is
It is possible to prevent as much as possible the sheet paper P from being caught in the feedout roller 31 and the presser roller 32 during feeding, resulting in a paper jam.

In addition, the perforation 91 for cutting out the sheet paper P is
It is possible to provide perforations throughout the toilet seat body 11 in a shape that matches the inner shape of the toilet seat body 11, or it is also possible to provide perforations here and there and make cuts elsewhere.

Further, as shown in FIG. 3 and FIG. 12, the sheet paper P has non-perforated portions 9 at regular intervals in the longitudinal direction.
2 and the tip of the perforation 91.
On the other hand, a position detection sensor 94 consisting of a light emitting element and a light receiving element is provided at the front part of the inclined ceiling wall 22 of the casing body 16 corresponding to the through hole 93.

The position detection sensor 94 detects the through hole 93 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 93, desired colored marks may be applied to the sheet paper P, and furthermore, the through-holes 93, etc., may be attached not only at the center of the sheet paper P but at any desired location. be able to.

Further, the above-mentioned supply and positioning of the sheet paper P can be performed by the rotation motor 4 without using the above-mentioned position detection sensor 94.
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. 1, reference numeral 96 is a seating detection means consisting of a reflective infrared sensor provided on the inner surface of the one side extension 25 of the casing body 16, and after the user is seated on the toilet seat body 11, When the user leaves the toilet seat main body 11 after a period of time (for example, 10 seconds) has elapsed, a detection signal is generated, the control unit F is activated, the rotation motor 75 is driven, and the clamp on the sheet paper P is released. At the same time, the movable plate 50 and the swing plate 51 can be moved from the position shown in FIG. 9 to the position shown in FIG. 10 so as to block the entry of dirty water into the sheet paper delivery path 8.

Note that the seating detection means 96 can be integrated into the automatic sheet paper supplying toilet seat A, or can be separated and made into a separate body, depending on the usage conditions and usage environment.

Furthermore, in addition to the above-mentioned infrared sensor, the seating detection means 96 may also use a micro switch, a limit switch, etc., or may detect the load when the seat is seated using a load cell, etc.
It is also possible to operate the

In addition, in FIG. 1, 97 is a state in which the toilet seat body 11 is not seated (when the toilet seat body 11 stands on its own), and the detection is removed from the toilet seat body 11.
This is an abnormal feeding prevention sensor that cuts off the power to the rotating motor 40 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 the abnormal delivery prevention sensor 97 may be a microswitch, a limit switch, or the like instead of a normal sensor.

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

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 above-mentioned rotation motor is mounted on the control unit mounting plate 100. A control panel 101 is attached to control the operation of 40.75, etc., and forms a control section F. Note that a transformer 102 is also integrally attached to the control panel 101.

Next, the operation section G will be explained as shown in FIGS. 1 and 3.
As is most obvious from the figure, the operation section G includes a push button 1031 for sheet paper feeding, a power lamp 104 consisting of a light emitting diode, etc., and a power lamp 104 for handling paper jams, paper replenishment, etc. It is constructed by installing a paper supply lamp 1059, a paper trouble lamp 106, etc., which have a warning function when an abnormality occurs.

Note that a buzzer or the like may be installed instead of the paper replenishment lamp 105 or the like.

Further, FIG. 13 shows an example of the circuit configuration of the control section F that controls the operation of the automatic sheet paper supplying toilet seat A.

As shown in FIG. 13, the control unit F is composed of a microprocessor MPU, input/output interfaces 110 and 111, and a memory M that stores a sheet paper feeding/cutting sequence program to be described below.

The input interface 110 is interposed between the sheet paper feeding push button 1031 position detection sensor 94, seating detection means 96, etc. and the microprocessor MPυ, and the output interface 111 is interposed between the microprocessor MPU and the sheet paper Feeding mechanism part C,
It is interposed between the sheet paper cutting mechanism and the sheet paper cutting mechanism.

A lock circuit Q is incorporated in the microprocessor MPU, and after the sheet paper P has been fed out for a predetermined length, the lock circuit Q is activated by the seating detection means 9.
As long as the output from 6 is sent to the control section F, the sheet paper P is not fed out even if the sheet paper feeding push button 103 is pressed.

Therefore, even if the user presses the sheet paper delivery push button 103 more than once by mistake or by a child or the like after sitting, the sheet paper P will only be delivered for one use.

Further, to explain other configurations in the illustrated embodiment, in FIG. It is possible to aim at cooling.

Below, sheet paper automatic supply toilet seat A having the above configuration
The operation will be explained 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 body 16 closes the sheet paper outlet 85 at all possible times, as shown in FIG. 8 is prevented from invading.

When using the flush toilet 10 in this state, as shown in FIG.
4 lights up (151).

Next, when the sheet paper feeding push button 103 is pressed (152), the rotation motor 75 of the sheet paper cutting mechanism section and the rotation motor 40 of the sheet paper feeding mechanism section C are sequentially activated by the drive signal from the control section F. Operate. The rotation of the disk cam 71 in the direction of the hour hand by the rotation motor 75 causes the movable plate 50 to rotate counterclockwise, changing from the posture shown in FIG. 10 to the posture shown in FIG. 4. . That is, a sheet paper delivery path 8 communicating with the sheet paper delivery port 85 is formed on the movable plate 50 (157).

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

However, when the sheet paper roll protection cover 84 is not mounted on the casing body 16, the cover safety switch (not shown) is in the OFF state.
Even if the sheet paper feeding push button 103 is pressed (1
52) Under the control of the control unit F, the drive signal is not sent from the control unit F to the rotation motor 40 (1
53N), the safety of operation can be ensured.

Furthermore, even if the user is sitting on the toilet seat main body 11 with the sheet paper P not being fed out, it is not preferable for the user to pay out the sheet paper P onto the toilet seat main body 11. to operate the control section F.
In addition, the drive signal is not sent to the rotation motor 40 (154N).

In addition, it is not preferable to feed out the sheet paper P onto the toilet seat body 11 when the toilet seat body 11 is standing.
The abnormal extension prevention sensor 97 detects that the toilet seat main body 11 is in an upright state, and the control section F is made not to send a drive signal to the rotation motor 40 (155N).

Furthermore, even when the position detection sensor 94 arranged inside the casing body 16 that also serves as paper detection detects that the sheet paper P is present in the sheet paper delivery path 8 inside the casing body 16, the sheet paper P is not fed out from the casing. Since the sheet paper P will be entangled in the main body 16, the detection output causes the control unit F to not send a drive signal to the rotation motor 40 (156).
.

If there is no abnormal condition mentioned above, as mentioned above,
A drive signal is sent from the control unit F to the rotary motor 40 to drive the rotary motor 40 (15B), and the sheet paper P is fed out from the sheet paper roll R.

Also, when the rotation motor 40 starts driving, the timer T
(Fig. 13) is activated (159). Then, the sheet paper P is fed out onto the toilet seat main body 11, and then the position detection sensor 94 detects that the sheet paper P is fed out normally, that is, for the set feeding time tl.
The sheet paper P is detected within the set time t.
2, when the through hole 93 provided in the sheet paper P is detected (159Y), the rotating motor 40 stops with the set length of the sheet paper P being fed out onto the toilet seat body (159Y).
160).

Note that, at this point, the cutting perforation 90 located at the rear end of the sheet paper P is located substantially directly below the sheet paper cutting blade 61a of the swing plate 51.

However, if there is an abnormality in the detection of the position detection sensor 94, the position detection sensor 94 may

turns off the rotation motor 40 and turns on the paper trouble lamp 106 (161).

Furthermore, even if the sheet paper P is detected within the set time Ll, the position detection sensor 94
When detecting the through hole 93 (159bY), the rotary motor (40) is similarly turned off and the paper supply lamp 105 is turned on (162).

Further, if the through hole 93 is not detected within the timer setting time t2 (159 cN), the rotary motor 40 is turned off and the paper trouble lamp 106 is turned on (16
3).

Thereafter, the user can take necessary measures such as replenishing paper and checking.

Then, the rotation motor 75 is restarted by a drive signal from the control unit F, and as shown in FIGS. and press roller 3
When the rotation motor 75 continues to be driven by continuous drive signals from the control unit F, tension is applied in the feeding direction to the portion of the sheet paper P located between the two clamped portions. becomes (164
).

Further, when the rotation motor 75 is driven by a drive signal from the control section F, the sheet paper cutting blade 61a of the sheet paper cutting section 61 of the swinging plate 51 as shown in FIG.
However, the sheet paper P is pressed along the cutting perforations 90, and the sheet paper P is reliably broken, ie, cut, by the pressing force and the tension in the feeding direction (165). 8. Therefore, the rear end of the cut sheet paper P is securely clamped by the sheet paper pressing pieces 56, 64 (165).

After that, when the user sits on the toilet seat body (169
), the seating detection means 96 detects that the seat is seated 17
0) Based on the detection output, the control section F controls so that even if the sheet paper feeding push button 103 is subsequently pressed, the drive signal is not sent to the rotation motor 40 as long as the seating detection means 96 detects the seat. Do (171).

Therefore, even if the user presses the sheet paper feeding push button 103 by mistake or mischievously while seated, the sheet paper P will not be fed out, so the casing body 1
Accidents such as entanglement of the sheet paper P within the sheet paper P can be reliably prevented.

When the user leaves the toilet seat body 11 after using the toilet (
172), the seating detection means 96 is turned off (173).
), based on the OFF signal, the control unit F controls the rotation motor 7.
The drive signal is sent again to the rotary motor 75 to rotate the rotary motor 75. As a result, the movable plate 50 and the swing plate 5
1 will take the state shown in FIG.

That is, while the clamp of the sheet paper P is released, the movable plate 50 is set in the casing body 16 in a position that can reliably prevent dirty water from entering the sheet paper delivery path 8 through the sheet paper delivery port 85. You can take (174) (175).

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

In the above step, after the sheet paper P is cut and held by the cooperation of the movable plate 50 and the swing plate 51 (165), but before the sheet paper P is seated (169), someone forcibly cuts the sheet paper If the sheet paper P is pulled out (166), or the sheet paper P fed out onto the toilet seat body 11 is wet, the push button 103 for sheet paper feeding is kept pressed for a predetermined time (about 5 seconds) to remove it. (167), furthermore,
For some reason, the user must remove the toilet seat body 1 within the specified time.
1 (168), the seating detection means 96
Regardless of the situation, in order to determine that the sheet paper P is unusable or to discard it as unused, the controller F sends a drive signal to the rotary motor 75 to cause the movable plate 50 and the swing plate 51 to , it is possible to take the state shown in FIG. 10, release the clamp on the sheet paper P, and close the sheet paper outlet 85 (174) (1
75).

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

That is, in the present invention, the sheet paper cutting mechanism section is controlled by the control section F so as to reliably clamp the rear end of the sheet paper P even after cutting the sheet paper P. Even if the user slightly moves his/her body, there is no fear that the sheet paper P will fall from the toilet seat main body 11, and the user can use the toilet comfortably.

Furthermore, when the user leaves the toilet seat main body 11 after using the toilet, the seating detection means detects this movement and causes the sheet paper cutting mechanism to release the clamping operation of the sheet paper P. Along with the cleaning operation, the sheet paper P can be rolled into the toilet bowl 10, and can also be easily grasped by hand and thrown into the toilet bowl 10 for disposal.

Further, when the user leaves the seat after using the toilet, the seating detection means detects the sitting and leaving action and controls the sheet paper cutting mechanism to block the sheet paper outlet 85. Intrusion of sewage into the casing body 16 through the sheet paper outlet 85 can be effectively prevented, and damage to functional parts within the casing body 16 can be prevented as much as possible.
