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, the configuration of the movable plate 50 will be explained as shown in FIGS. 4 and 5.
As shown in the figure, the movable plate 50 is formed from a long and wide rectangular flat plate extending in the left-right direction, and has pivots 52.53 protruding from both ends thereof.
3 to the left and right side walls 18.1 of the casing body 16, respectively.
It is rotatably supported on 9.

Moreover, 54.55 is a biasing spring attached to the pivot shaft 52.53 in order to keep the guide roller 70 (described later) in constant contact with the disk 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 types of shafts 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 stoppers 67 and 68 protruding from the inner surface of the swing plate 24, the swing plate is moved to the standby position shown in FIG. 51 can be held.

Next, the drive mechanism of the sheet paper cutting mechanism consisting of the movable plate 50 and the swing plate 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.
1, and a rotating 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, an example of the extension portion of the rotating shaft 72 is the left side wall 1B.
through the sheet paper roll mounting wall 23 and the outer ff
The extension portion extends into a compartment 23b formed between 23a and 23a, and the extension portion 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 circumferential surface of the disc cam 71 draws a cam locus within an irregular shape, and the guide roller has a circumferential surface that comes into contact with the same amount of surface. 70 moves up and down, and this up and down movement allows the movable plate 50 to swing around the pivots 52 and 53, and in conjunction with the swinging of the movable play 50, the swing play 51 also swings. By moving, 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 positioned approximately directly below the cutting blade 61a of the sheet paper cutting section 61 of the swing play 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 shaft 52,53 via the guide roller 70, and as shown in FIG. As shown, the sheet paper pressing piece 56 clamps the sheet paper P together with the sheet holder ff pressing piece 64 of the swing plate 51. Then, the portion of the sheet paper P located between the clamp portion and the clamp portion where the feeding roller 31 and the holding roller 32 come into contact is pressed and bent upward by the rear end of the movable plate 50, and tension is applied to the sheet paper P. Add.

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 90.

Then, the sheet paper P after cutting is the pressing piece 56.64
continues to be clamped by.

When the user leaves the toilet seat main body 11 after sitting down and relieving himself, the seat lifting means 96 (to be described later) causes the user to move away from the seat, and the lifting signal is sent to the control unit F.
Further, the disc cam 71 rotates clockwise, and the movable plate 50 rotates clockwise this time and assumes the position shown in FIG. 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.

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

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

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 described.

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.

Furthermore, as shown in FIGS. 5 and 11, both ends of the sheet paper roll protective cover 84 are provided with fitting grooves 88 and 89 recessed along the inner edge of the sheet paper roll mounting wall '23. engaged.

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, in the unlikely event that a problem occurs due to the sheet paper P becoming clogged or entangled in the sheet paper delivery path 8, etc.,
As shown in FIG. 11, after removing the sheet paper roll protection cover 84, the tangled sheet paper P can be easily removed by swinging the hanging support frame 33 forward.

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 cylindrical part I4 provided at the rear of the toilet seat main body 11. This is to enable automatic and accurate feeding onto the upper surface of the main body 11.

In addition, 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 has a non-perforated part 92 between its rear ends, so when the cutout perforation 91 is cut out, the cut out central part is It drips into the flush toilet bowl 10, and its lower end is 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 92 and the cutout perforations 9I 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 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.

Mata, the perforation 91 for cutting out 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 cutout perforation 91, a position detection through hole 93 is provided, and a light emitting element is provided in the front part of the inclined ceiling wall 22 of the casing body 16 corresponding to the through hole 93. A position detection sensor 94 consisting of a light receiving element and a light receiving element is provided.

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.

Furthermore, in this embodiment, as shown in FIG. The interval D1 is shorter than the normal interval D2 of other parts.

Therefore, the position detection sensor 94 detects the position detection through hole 93 earlier than the set time with respect to the sheet paper P forming the end portion of the sheet paper R.
Paper replenishment lamp 10 is activated by the output of timer T1, which will be described later.
5 etc. can be turned on to quickly notify the user of the paper out condition.

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, in FIG. 1, reference numeral 96 denotes a seating detection means consisting of a reflective infrared sensor etc. provided on the inner surface of the one side extension 25 of the casing main body 16, and after the user is seated on the toilet seat main body ll, When the user leaves the toilet seat main body 11 after a period of time (for example, 5 seconds) has elapsed, a detection signal is generated, the control unit F is activated, the clamp on the sheet paper P is released, and the sewage sheet-paper delivery path is generated. 8, 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.

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

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 operations of 4G and 75, 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 sheet paper feeding push button 103. It is constructed by installing a power lamp 104 made of a light emitting diode or the like, a paper replenishment lamp 1051 and a paper trouble lamp 106, which have a warning function in case of an abnormality such as a paper jam or paper replenishment.

In addition, in place of the paper replenishment lamp 105, etc., an alarm buzzer Bu
etc. can also be installed.

Further, FIG. 13 shows the configuration of a control device that controls the operation of the automatic sheet paper supplying toilet seat A.

As shown in FIG. 13, the control unit F includes a microprocessor MPU and an input/output interface 110.

111, and a memory M that stores a sheet paper feeding/cutting order program to be described below.

The input interface 110 is interposed between the sheet paper feeding push button 103, the position detection sensor means 94, the seating detection means 96, etc. and the microprocessor υ, and the output interface 111 is interposed between the microprocessor MPU and the like. It is interposed between the sheet paper feeding mechanism section C, the sheet paper cutting mechanism section, etc.

Further, the control section F is equipped with a timer T1, and as described above, the interval 01 between the position detection through holes 93 and 93 at the end of the sheet paper roll R is made shorter than the interval D2 at other parts. Due to this, when the position detection sensor 94, which operates simultaneously with the start of the feeding operation by the sheet paper feeding motor 40, detects the through hole 93 of the sheet paper P earlier than the set time,
The output is sent to the control unit F, and the alarm buzzer Bu and paper replenishment lamp 105 can be operated via the abnormal character signal generator J.

Therefore, users etc. can easily discover that the sheet paper P has been used up and is out of paper, and after that, they can quickly take appropriate countermeasures, specifically, the sheet paper roll R.
can be replaced.

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. 15(^) and 15(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. Then, the movable plate 50 rotates counterclockwise due to the clockwise rotation of the disc cam 71 driven by the rotation motor 75, and takes the posture shown in FIG. 4 from the posture shown in FIG. 10. . 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
53), safety of operation can be ensured.

In addition, the user may place sheet paper P on the toilet seat body.
Even when the user is seated in a state where the sheet paper P is not extended, it is not preferable to extend the sheet paper P onto the seat main body 11. Therefore, the seating detection means 96 is activated and a drive signal is sent to the control unit F to the rotation motor. 40 (154).

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 body 11 is in the upright state, and the control section F is prevented from sending a drive signal to the rotation motor 40 (155).

Furthermore, even when the position detection sensor 94 that also serves as paper detection located inside the casing body 16 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. Since the sheet paper P will be entangled in the section casing 15, the detection output causes the control section 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 (158), and the sheet paper P is fed out from the sheet paper roll R.

Also, when the rotation motor 40 starts driving, the timer T2
(Fig. 13) is activated (159). Then, the sheet paper P is fed out onto the toilet seat main body ll, and then the position detection sensor 94 detects the sheet paper P normally, that is, within the set time tl, and at the same time, the sheet paper P is fed out onto the toilet seat main body ll.
When the through hole 93 provided in the sheet paper P is detected in the toilet seat 2 (159cY), the rotary motor 40 stops with the set length of the sheet paper P being fed out onto the toilet seat body 11 (160). At this point, sheet paper P
The cutting perforation 90 located at the rear end is located approximately 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, that is, within the set feeding time tl, the position detection sensor 94
4 does not detect sheet paper P (159aN)
turns off the automatic sheet paper feeding motor 40 and turns on the paper trouble lamp 106 (161).
).

Further, even if the sheet paper P is detected within the set time tl, if the position detection sensor 94 detects the through hole 93 earlier than the next timer set time t2 (counting from the start of driving the rotation motor 40), (159bY) similarly turns off the rotary motor 40, and also turns off the paper supply lamp 10.
5 is turned on (162).

Furthermore, 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 (159 cN).
63).

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. (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).

Thus, 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 11 (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 takes the state shown in Fig. 1θ.

That is, while the clamp of the sheet paper P is released, the movable plate 50 maintains a position inside the casing body 16 that can reliably prevent sewage from entering the sheet paper delivery path 8 through the sheet paper delivery port 85. (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 main body 11 is wet, the sheet paper feeding push button 103 is pressed for a predetermined period of time (approximately 5 seconds) to remove it. If continued (167), furthermore,
For some reason, the user must remove the toilet seat body 1 within the specified time.
1 (168), each reset means (not shown) sends a drive signal to the control unit F to drive the rotation motor in order to discard the sheet paper P as unused, regardless of the seating detection means 96. 75 to cause the movable plate 50 and the swing plate 51 to assume the state shown in FIG. 10, thereby releasing the clamp on the sheet paper P and closing the sheet paper outlet 85 (174) (175 ).

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

In addition, when the sheet paper roll R is out of paper, the controller F is informed that if the position detection means generates a detection output earlier than the set time, it is determined that the sheet paper roll R is used up, and the sheet paper roll R is used up. Turn off the feeding mechanism section C.
F, and the abnormality signal generating device J is configured to issue an abnormality signal, so it is possible to quickly discover the paper-out state of the sheet paper roll R, and then,
Appropriate measures such as replacing the sheet paper roll R can be quickly taken, and the usability is improved.
