Abstract

PURPOSE:To prevent the intrusion of a dirty water into a functional part casing by completely closing a seat paper sending port when a seat paper position detecting sensor does not detect the seat paper by means of the removal of the seat paper. CONSTITUTION:By an off-output at the time of leaving the seat after an excretion, by the output at the time of pushing a seat paper supplying switch again or when a seating detecting means does not detect the seating even after a prescribed time passes, a seat paper cutting mechanism D is moved to a seat paper hold releasing position to release the clamp of a seat paper P and to make a sending port 8a into an opened condition, the seat paper P can be easily removed, and it can be rejected into a closet. When a seat paper position detecting sensor 70 does not detect the seat paper P, a seat paper supplying mechanism part C and the seat paper cutting mechanism part D are returned to an origin position in which the seat paper sending port 8a is made into the full opened condition, the clamp of the seat paper P is released and the seat paper P is made suppliable by the next operation of a seat paper supplying switch 71. Since the seat paper sending port 8a is in the full closed condition, the intrusion of the dirty water into a functional part casing 15 is surely prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an automatic sheet paper supplying toilet seat that can automatically supply sheet paper onto the toilet seat.

(b) Prior art The present applicant previously disclosed in Japanese Patent Application No. 63-40488,
An automatic sheet paper supplying toilet seat having the following configuration has been disclosed.

In other words, the automatic sheet paper supply toilet seat has a sheet paper roll and a Meno Sheet Heber feeding mechanism that feeds out the sheet paper from the sheet paper roll onto the top surface of the toilet seat body, in a functional casing provided at the rear of the toilet seat body. control the sheet paper cutting mechanism that cuts the rear end of the bar, the sheet paper feeding mechanism, and the sheet paper cutting mechanism. The toilet seat is characterized by a configuration in which a control unit that drives the sheet paper to feed out a set length onto the toilet seat body and cut the rear end, and an operation unit that operates the control unit are housed in an integrated manner. .

In addition, with this configuration, when the sheet paper feed switch is operated, the sheet paper position detection sensor detects the through holes provided in the sheet paper at regular intervals, and the sheet paper is automatically placed on the toilet seat body by a set length. After accurately and precisely unwinding, positioning, and cutting the rear end, the cut end can be clamped.

Thereafter, after the user sits on the toilet seat main body, the sheet paper delivery port of the sheet paper delivery path is closed by the sewage prevention barrier based on the off output of the seating means when the user takes the seat.

Finally, after using the toilet, the user pulls out the sheet paper from the sheet paper outlet, removes it, and discards it in the toilet bowl.

Therefore, when using the sheet paper in a public place, the user can take out the sheet paper and use it without touching it directly, which improves hygiene.

(c) Problems to be solved by the invention However, in the above series of sheet paper feeding operations,
The sheet paper removal work is carried out with the sheet paper outlet closed with a sewage prevention barrier.

Therefore, in order to enhance the sewage prevention function, it is necessary to increase the closing force of the sewage prevention barrier, but this makes the sheet paper removal work difficult.

On the other hand, in order to facilitate the work of removing sheet paper, it is necessary to reduce the blocking force of the sewage prevention barrier, but this weakens the function of preventing sewage from entering the functional part casing.

In this way, with conventional sheet paper automatic supply toilet seats,
It was not possible to improve both the sewage prevention function and the sheet paper removal function.

An object of the present invention is to provide an automatic sheet paper supply toilet seat that can solve the above problems.

(d) Lllll! Means for Solving the Problems The present invention has a function part casing, on a sheet paper feeding mechanism part that feeds out sheet paper from a sheet paper roll through a sheet paper delivery path onto the toilet seat body, and cuts the rear end of the fed sheet paper. a sheet paper cutting mechanism section that clamps the cut end and is capable of opening and closing the sheet paper delivery port of the sheet paper delivery path; and a control section that controls the operations of the sheet paper feeding mechanism section and the sheet paper cutting mechanism section. In the sheet paper automatic supplying toilet seat, the control unit controls the sheet paper cutting unit to release the sheet paper clamp after the sheet paper is delivered onto the toilet seat main body, the cutting operation is performed, and the clamping operation is performed. Move to the sheet paper holding release position where the paper feed port is open, and then
This invention relates to an automatic sheet paper supplying toilet seat characterized by comprising a control program that fully closes a sheet paper outlet when the sheet paper detection means no longer detects the sheet paper fed out onto the toilet seat body. be.

In addition, in the above control program, the movement of the sheet paper cutting mechanism to the sheet paper holding release position is
By the OFF output when the user sits on the toilet seat body and then leaves the seat, ■ by the output when the sheet paper feed switch is pressed again, or ■ by the operation of sitting on the toilet seat body,
This is performed when the seating detection means does not detect seating even after a predetermined period of time has elapsed.

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

That is, in the present invention, the off output is activated when the user leaves the seat after using the toilet, the output when the sheet paper feeding switch is pressed again, or even after a predetermined period of time has elapsed without the user sitting on the toilet seat body. When the seating detection means does not detect seating, the sheet paper cutting mechanism can be moved to a sheet paper holding release position where the sheet paper is unclamped and the sheet paper delivery port is opened; At the sheet paper holding release position,
The sheet paper can be easily removed from the sheet paper outlet and disposed of in the toilet bowl.

After that, when the sheet paper position detection sensor does not detect the sheet paper due to the removal of the sheet paper, the sheet paper feeding mechanism section and the sheet paper cutting mechanism section are set so that the sheet paper feeding port is fully opened and the sheet paper is clamped. is released, and the sheet paper can be returned to the original position where it can be fed by the next operation of the sheet paper feeding switch. Since the sheet paper outlet is in a fully closed state at the same origin position, it is possible to reliably prevent sewage from entering the functional unit casing.

As described above, in the present invention, it is possible to easily and reliably remove and dispose of sheet paper and prevent the intrusion of sewage.

It is composed of a swing plate 51 that is swingably supported on an installed pivot shaft 52.

In addition, in FIG. 5, BP is a sewage prevention barrier attached to the front of the upper end of the movable plate 50, which can take the original position in the operation sequence of the automatic sheet paper supplying toilet seat A, which will be described later, and the sheet paper is fed out. Road 8
The sheet paper outlet 8a formed in the front part of the casing 15 can be completely shielded to reliably prevent sewage and the like from entering the functional part casing 15.

Furthermore, in FIG. 5, 56 is a sheet paper pressing piece made of an elastic material, and is provided at the rear of the upper surface of the movable plate 50. The sheet paper pressing piece 56 cooperates with a sheet paper pressing piece 57 forming the front part of the swing plate 51 to clamp the sheet paper P.

Further, as shown in FIG. 5, the swing plate 51 is formed with a sheet paper cutting section 58, which is integrated with the sheet paper pressing piece 57 described above, at the rear thereof.

With this configuration, when the cam movement drive motor 41 is driven, the power transmission shaft 43 rotates, and the disc cam 44 that is integral with the power transmission shaft 43 also rotates about the axis of the power transmission shaft 43. Become.

Since the center of the disc cam 44 is eccentric from the axis of the power transmission shaft 43, the peripheral surface of the disc cam 44 draws a cam locus with an irregularly shaped edge, and the movable plate 5 in contact with the peripheral surface
0 can be oscillated about the pivot 49, and in conjunction with the oscillation of the movable plate 50, the oscillating plate 5
1 also swings, and the sheet paper P can be effectively pressed and cut by the sheet paper cutting section 58.

Next, the configuration of the sheet paper roll storage section E disposed within the upper casing 17 will be described.

4 to 7, reference numerals 60 and 61 are sheet paper roll holders rotatably attached to the left and right bearing boxes 30 and 31, respectively, and the sheet paper roll holder 6 (1 and 61 is a sheet paper roll holder). By supporting both ends of R, the sheet paper roll R formed by winding the sheet paper P multiple times around the paper tube can be exchangeably stored in the sheet paper roll storage section.

The above configuration will be described in more detail below. In FIG. 8, the base end of the holder mounting cylinder 62 is rotatably moved forward and backward within the cylindrical boss 38 rotatably supported in the left bearing box 30. It is arranged.

The holder attachment tube 62 houses a spring 63 therein, and the spring 63 urges the holder attachment tube 62 in the advancing direction.

Further, the sheet paper roll holder 60 is rotatably attached to the extending end of the holder attachment cylinder 62 by a pull-out prevention plug 64.

On the other hand, a sheet paper roll holder 61 is rotatably attached to a cylindrical boss portion 39 rotatably supported within the right bearing box 31 by a plug 64 to prevent removal.

With this configuration, the spring 63 is compressed to move the halter attachment cylinder 62 and the sheet paper roll holder 60 backward, and the sheet paper roll holders 60 and 61 can support both ends of the paper tube R1 of the sheet paper roll R. .

In addition, in the case where the sheet paper P on the paper tube R+ has run out, which is a so-called paper out state, the spring 63 is compressed again to move the holder mounting tube 62 and the sheet paper roll holder 60 backward, and the sheet paper roll holder 6
From 0.61, both ends of the paper tube R3 of the sheet paper roll R can be removed as shown by imaginary lines in FIG. 8, and replaced with a new sheet paper roll R.

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.
It is located on the front right side of the

As shown in FIG. 9, the control section F essentially includes a microprocessor (MPIJ) m and a sheet that generates an output by detecting a through hole for detecting the sheet paper position provided in the sheet paper P. Controls such as a paper position detection sensor 70, a sheet paper feed switch 71 provided in the operation section G, and a seating detection means 72, etc., which will be described later? An input interface n connected to an output generating means, an output interface 0 connected to a sheet paper feeding mechanism section C, a sheet paper cutting mechanism section, etc., a memory p and a timer q for storing sheet paper feeding, clamping, and cutting programs. It consists of

In addition, in FIG. 9, " is a drive circuit interposed between the output interface 0 and the sheet paper feeding machine lateral section C or the sheet paper cutting mechanism section, and S is a power supply circuit connected to the drive circuit r. be.

Next, the operating section G will be explained. As shown in FIG. It is constructed by attaching a power lamp consisting of a power lamp, a paper trouble lamp, etc., which has an alarm function in the event of an abnormality such as a paper jam or paper replenishment.

Next, a position detection sensor 7 that detects the sheet paper position detection transparent hole provided in the sheet paper P and generates an output.
0, such a sensor 70 is, for example,
It can be formed by combining a phototransistor and a photodiode.

Then, as shown in Figures 3 and 4 and Figure 1O,
In this embodiment, the sheet paper position detection sensor 70 is
It is disposed at the front right side of the functional part casing 15, and can detect position detection through holes provided at regular intervals in the sheet paper P.

That is, when the sheet paper P is fed out a predetermined length from the sheet paper roll R onto the toilet seat main body 11 by the drive of the sheet paper feeding mechanism section C, the position detection through-hole is detected by the sheet paper position detection sensor 70. Then, the operation of the sheet paper dispensing mechanism section C is stopped, and the sheet paper P can be accurately supplied and positioned on the toilet seat main body 11.

In addition, in this example, sheet paper! The detection sensor 70 is covered by a waterproof cover 70a, as shown in FIG. The physical connection is made by a pair of lead wires It, It passing through the cylindrical boss portion 39.

Next, the configuration of the seating detection means 72 will be specifically explained with reference to FIGS. 11 to 14.

As shown in FIG. 11, both rear ends of the toilet seat body 11 are
By the functional axis 13 and the simple axis 13a, respectively,
Pivot parts 15a provided on both sides of the front part of the functional part casing 15
, 15b, it is detachably attached and rotatable in the vertical direction. The seating detection means 72 is disposed within the pivot portion 15a and is operatively connected to the functional pivot 13.

As shown in FIGS. 12 to 14, the functional pivot 13 has an elongated hole 7 formed vertically in the inner wall 74 of the pivot portion 15a.
5 and inserted into the pivot portion 15a.

The insertion portion of the functional pivot 13 is rotatably supported by a movable bearing 77 that is disposed within the elevating guide casing 76 so as to be movable up and down.

Note that the movable bearing 77 is always urged upward by the coil spring 78, but its upper limit position is regulated by the regulation plate 79, so normally the first
The functional pivot 13 and the toilet seat body 11 will also assume the upper position shown in Figure 3 (the position in which the user is not seated).

The functional pivot 13 also has a lever pressing piece 8 at its insertion tip.
As is clear from FIG. 13, the lever pressing piece 80 is shown as a segment of approximately a quarter arc whose center is the same as the axis of the functional pivot 13.
The radius of the outer periphery of the segment is considerably larger than the radius of the functional axis 13.

Note that the shape of the lever pressing piece 80 is not limited to a substantially quarter arc segment, and is not limited to this as long as the radius of the outer circumferential edge is considerably larger than the radius of the functional pivot 13.

Furthermore, a sensor activation lever 81 having an L-shape in plan view is disposed below the lever pressing piece 80.

The sensor activation lever 81 is supported such that its proximal end 81a can be raised and lowered in an upwardly biased state within a lever elevating guide casing 83 having a built-in coil spring 82 therein, and a shielding plate is attached to its distal end 81b. 84 is installed protrudingly.

Therefore, the upper surface of the sensor activation lever 81 is always in contact with the lever pressing piece 80 by the coil spring 82.

The shielding plate 84 also covers a light emitting element 85 of an infrared sensor 85 disposed within the pivot portion 15a of the functional unit casing 15.
a and the light receiving element 85b.

Next, the operation of the seating detection means 72 having the above configuration will be explained.

When a user sits on the toilet seat main body 11, the user's weight causes the power pivot 1 to move against the biasing force of the coil spring 8.
3. The movable bearing 77 and the lever pressing piece 80 are lowered together, and in conjunction with the lowering, the sensor activation lever 81 is also lowered,
Since the shielding plate 84 releases the conduction shielding between the light projecting element 85a and the light receiving element 85b, the infrared sensor 85 can generate an ON output.

On the other hand, when the user leaves the toilet seat body 11, the weight is released, and the urging force of the coil spring 78 causes the function pivot 13. Movable bearing 77 and lever pressing piece 80
are raised integrally, and in conjunction with the rise, the sensor activation lever 81 is also raised by the biasing force of the coil spring 82.
Since the shielding plate 84 interrupts conduction between the light projecting element (photodiode) 85a and the light receiving element (phototransistor) 85b, the infrared sensor 85 can generate an off output.

The detection output of the seat detection means 72 having the above configuration can cause each mechanism in the automatic sheet paper supply toilet seat to perform arbitrary operations, but in this embodiment, the following operations are performed. There is.

That is, the seating detection means 72 generates a detection signal when the user leaves the toilet seat body 11 after a certain period of time has passed after the user sits on the toilet seat body 11, and activates the control unit F.
The clamping of the sheet paper P by the sheet paper cutting mechanism section C can be released.

Thereafter, when the user removes the used sheet paper P, the movable plate 50 is rotated in response to a signal from the sheet paper position detection sensor 70 so as to block the entry of dirty water into the sheet paper delivery path 8.

Further, the seating detection means 72 detects whether the user is seated on the toilet seat body 11 or
While the user is sitting on the seat, the sheet paper P is not fed out even if the sheet paper feeding push button switch 71 is pressed.

Furthermore, in this embodiment, as shown in FIGS. 11 and 12, the seating detection means 72 is configured to also function as a toilet seat main body upright detection means.

That is, as shown in both figures, a toilet seat main body retaining portion 86 is provided on the toilet seat main body side of the functional axis 13 and has a flat cross-sectional shape and is formed by cutting 180 degrees opposite sides. The portion 86 is removably provided on a corresponding side of the rear portion of the toilet seat main body 11 and is fitted into a pivot retaining hole 87 having the same shape as the toilet seat main body retaining portion 86 .

Therefore, relative rotation is not possible between the toilet seat body 11 and the machine aEX axis 13, so when the toilet seat body 11 is rotated and raised,
The functional pivot 13 also rotates integrally, and this rotation also causes the lever pressing piece 80 provided at the insertion end of the functional pivot 13 to rotate.

By the way, since the radius of the lever pressing piece 80 is considerably larger than the radius of the functional axis 13, the lever pressing piece 80
, the functional pivot 13. is rotated against the biasing force of the coil spring 78. The movable bearing 77 and the lever pressing piece 80 lower together, and in conjunction with the lowering, the sensor activation lever 8
The shielding plate 84 also lowers the light emitting element 85a and the light receiving element 8.
Since the conduction shielding with 5b is released, the infrared sensor 85 can generate an ON output.

On the other hand, when the toilet seat main body 11 is returned from the upright position to the horizontal sitting position, the pressing force of the lever pressing piece 80 on the sensor activation lever 81 is released, so the urging force of the coil spring 78 is applied to the functional axis 13. The movable bearing 77 and the lever pressing piece 80 rise together, and in conjunction with the rise, the sensor activation lever 81 also rises due to the urging force of the coil spring 82, and the shielding plate 84 connects the light emitting element 85a and the light receiving element 85b. Since the conduction is interrupted, the infrared sensor 85 can generate an off output.

Based on the sensor output, the control section F controls the sheet paper feeding mechanism section C to stop operating when the toilet seat main body 11 is in the upright state.
Or, even if the sheet paper feeding switch 71 is pressed as a prank, it is possible to prevent the sheet paper P from being fed out from the functional part casing 15, and to ensure that the sheet paper P does not become entangled or clogged within the functional part casing 15. can be prevented.

Next, the configuration and operation of the movable plate position detection sensors 93, 93a that detect the current rotated position of the movable plate 50 will be explained in FIGS. 6, 7, and 14 to 16.
This will be explained with reference to the figures.

The movable plate position detection sensor 93.93a is provided on the bottom surface of the casing 94 near the center of the power transmission shaft 43 to which the disc cam 44 is fixed, so as not to hinder the rotation of the power transmission shaft 43. sensor mounting box 95
They are housed side by side inside.

The movable plate position detection sensors 93, 93a are
As shown in FIGS. 14 and 15, the planar shape is U-shaped, and a light-emitting element (photodiode) and a light-receiving element (phototransistor) are respectively provided on the opposing walls of this U-shaped part. are doing.

Furthermore, a pair of detection plates 96 and 96a fixed to the power transmission shaft 43 at a constant interval in the axial direction are loosely fitted into the U-shaped portions of the movable plate position detection sensors 93 and 93a, respectively.

As shown in FIGS. 15 and 16, the detection plates 96 and 96a are formed in an arc shape with a cutout portion i h of approximately 1/3, and as shown in FIG. In this state, the attachment positions of the notches g and h to the power transmission shaft 43 are shifted in the circumferential direction so that the notch angle θ is about 50 degrees.

With this configuration, the movable plate position detection sensor 93
．． 93a indicates the rotational position of the movable plate 50 that moves in conjunction with the disk cam 44 fixed to the power transmission shaft 43 in response to the blocking and opening of light from the light emitting element due to the rotation of the power transmission shaft 43. The moving position can be detected.

That is, by rotating the detection plates 96, 96a, the movable plate position detection sensors 93, 93a move to each operating position W(a) shown in an explanatory diagram (FIG. 18) showing the operating sequence of the automatic sheet paper supplying toilet seat A, which will be described later. ~ (h) Movable plate 50
It is possible to reliably detect that the sheet paper has come loose, and based on the detection output, the sheet paper feeding mechanism section C etc. can be accurately driven to perform a desired operation.

The above-mentioned movable plate position IT detection sensor 93, 93a,
The relationship between the position of the detection plate 96, 96a (FIG. 16) and the above operating positions (a) to (h) (FIG. 18) is shown in a table as follows.

Next, the structure of the sheet paper P will be explained with reference to FIG. 17. The sheet paper P has linear cutting perforations C in the width direction at regular intervals in the elongated direction or the feeding direction. , the sheet paper P is pressed and cut along the same perforation C.

In addition, the sheet paper P has a cut-out perforation a in the center between the cut-out perforation C1C and a shape that matches the inner shape of the toilet seat body 1. By cutting out the sheet paper P, an opening communicating with the inside of the flush toilet bowl 10 can be provided.

However, the cut-out perforation a is not completely annular, and a non-perforated part d is formed between both ends of the rear part, so when the cut-out perforation a is cut out, the cut center part is , drips into the flush toilet bowl 10, and its lower end is submerged in standing water.

Further, the sheet paper P has through holes for detecting the sheet paper position at regular intervals in the longitudinal direction, for example, at the edge corresponding to the edge between the non-perforated part d and the tip of the perforation a for cutting out. It is set up.

Next, regarding the operation of using the automatic sheet paper supplying toilet seat having the above configuration, with reference to the operation sequence explanatory diagram shown in FIG. 18 and the flowcharts shown in FIGS. 19 to 21,
Explain in detail.

First, to explain the normal operation sequence in which no trouble occurs (normal operation routine NR shown by the bold line in Fig. 19), each mechanism section C, D, control section F, operation section G, and each of the automatic sheet paper supplying toilet seat A, Sensor 70.85.
If the sheet paper position detection sensor 70 does not detect the sheet paper P (IOIN), the cam movement drive motor 41 is turned on regardless of the position of the movable plate 50. , driven according to the cam movement subroutine SR to be described later (10
2) Return to the home position.

Here, the origin position is a position where the sheet paper outlet 8a is completely blocked by the barrier plate BP provided at the tip of the movable plate 50, as shown in FIG. 18(a). Note that the movable plate 50 is at the origin position, and the sheet paper feeding mechanism section C, sheet paper cutting mechanism section, etc. are in a state where they can wait for the operation of the sheet paper feeding switch 71 and start a series of sheet paper feeding operations. is called a standby state.

That is, at the origin position, as shown in FIG. 18(a), the sheet paper outlet 8a is closed at all costs to prevent sewage, etc. from entering the sheet paper outlet path 8 from the sheet paper outlet 8a. is being prevented.

Further, if the sheet paper position detection sensor 70 does not detect the sheet paper P (IOIN) and the movable plate 50 is already at the origin position, the origin position return operation (102) is determined to be unnecessary, and the same operation is performed. - will not be carried out.

Even when replacing the sheet paper roll R, the above steps (101) and (102) are passed through.

That is, the upper casing 17 is removed from the lower casing 16, the paper tube R1 on which sheet paper P is not wound is removed from the sheet paper holder 60, 61, and a new sheet paper roll R is inserted into the sheet paper holder 6.
Attach it to 0.61.

After that, from the sheet paper roll R to the sheet paper P
The sheet paper P is rewound with a length sufficient to hold it between the delivery roller 33 and the press roller 34, and in such a state that the sheet paper position detection sensor 70 does not detect the sheet paper P, and then hung. Swing the supporting frame 35 forward and move the unwinding end of the sheet paper P to the feeding roller 3.
3 and a pressing roller 34.

Thereafter, when the sheet paper feed switch 71 is pressed, the operation proceeds through steps (101) and (102).

In this state, when using the flush toilet 10 now, when the sheet paper feeding switch 71 is pressed (103), an operation start signal is inputted to the control unit F, and the sheet paper feeding/cutting order program read from the memory ρ is generated. Based on this, the control unit F generates a drive signal, and the drive signal causes the first
As shown in FIGS. 8(a) and 8(b), the cam moving drive motor 41 of the sheet paper cutting mechanism is activated.

8, press the sheet paper feed switch 71 (10
3) First, the seating detection means 70 detects whether the person is seated on the toilet seat body l.
104), and if the toilet seat body 11 is not seated or standing up (104N), the cam movement subroutine SR, (FIG. 20) The cam movement drive motor 41 is driven according to the operation sequence in (10).
5) Due to the same drive, the movable plate 50 is rotated counterclockwise by the clockwise rotation of the disc cam 44,
A sheet paper delivery path 8 communicating with the sheet paper delivery port 8a is formed on the movable plate 50 (FIG. 18(b)).

Thereafter, as shown in FIGS. 18(c), (d), (e), and (f), the sheet paper feeding subroutine 5Rz(
According to the operation sequence in Fig. 21), the sheet paper feeding drive motor 40 and the cam movement drive motor 41
is driven (106), the sheet paper P is fed out from the sheet paper roll R, the sheet paper P is clamped and tension is applied, and the sheet paper P is torn at the perforation C.

In addition, in the above step, if the toilet seat main body 11 is in the rotating upright state or the user is seated due to some reason including mischief, the seating detection means 72 should detect this fact (104Y) and output the same detection output. As long as there are
Therefore, the sheet paper P is not fed out (104Y).

Then, when the toilet seat main body 11 is returned to its original horizontal seating position, the seating detection means 72 is turned off (104N), and step (
105) The movable plate 50 moves via (106) to open the sheet paper outlet 8a, and
It becomes possible to automatically feed out the sheet paper P onto the toilet seat body 11 (106).

Then, the sheet paper P is fed out onto the toilet seat main body 11, and then the sheet paper position detection sensor 70
When the through hole provided in the sheet paper P is detected within a predetermined time, the sheet paper feeding drive motor 4 is activated to feed out the sheet paper P by a set length onto the toilet seat body 11.
0 stops (FIG. 18(d)).

At this point, the perforation C located at the rear end of the sheet paper P is 1? It is located substantially directly below the sheet paper cutting section 58 of the moving plate 51.

Thereafter, the cam movement drive motor 41 is restarted by a drive signal from the control unit F, and the sheet paper P is clamped (held) between the sheet paper pressing pieces 56 and 57, and also between the feeding roller 33 and the holding roller 34. When the cam movement drive motor 41 continues to drive after the clamping (holding), tension in the feeding direction is applied to the portion of the sheet paper P located between the two clamped portions (see FIG. 18). e)).

Further, when the cam movement drive motor 41 continues to drive,
1? The sheet paper cutting section 58 of the moving plate 51 presses the sheet paper P along the perforations C, and the sheet paper P is cut by the pressing force and the tension in the feeding direction.
will surely break, that is, be cut (FIG. 18(f)).

Thus, the rear end of the cut sheet paper P is securely clamped by the sheet paper pressing pieces 56 and 57 (FIG. 18(f)).

Thereafter, when the user sits on the toilet seat main body 11, the seating detection means 72 detects that the user is seated (108), the swearing prevention time (for example, 5 seconds) elapses (109), and then after using the toilet, the user sits on the toilet seat. When the person leaves the main body 11, the seating detection means 72 turns off (110), and if the off signal is output continuously for 2 seconds or more (IIIY), the control unit F controls the cam movement drive motor 41. The drive signal is sent again to drive the cam movement drive motor 41 to the cam movement subroutine SR shown in FIG.

Based on this, the movable plate 50 is driven until it moves to a position where the sheet paper can be removed (112). As a result, the clamp on the sheet paper P is released (FIG. 18(g)).

After that, the user removes the sheet paper P from the toilet seat main body 11 (113) or drives the cleaning device to clean the inside of the flush toilet bowl 10, and the force of the flush water causes the flush water to flow out.
The cut-off portion of the sheet paper P can be drawn in and flowed out together with the dirt, and the sheet paper P can be removed (113).

Then, if sheet paper P is excluded (113
Y), the sheet paper position detection sensor 70 detects this, and the detection output causes the cam movement drive motor 4 to
1 in the subroutine St? shown in FIG. .

is driven until it returns to the origin position based on (114),
The sheet paper outlet 8a is completely closed by the sewage prevention barrier HP provided at the tip of the movable plate 50 (
Figure 18(h)).

That is, the movable plate 50 can take a position within the functional unit casing 15 that can reliably prevent dirty water from entering the sheet paper delivery path 8 through the sheet paper delivery port 8a.

Thereafter, the sheet paper feeding drive motor 40 is restarted, and the leading edge of the sheet paper P is advanced from the sheet paper delivery port 8a by a small length, for example, 20III, toward the toilet seat body 11 to prevent paper jams. The sheet paper is fed out (115), and the user presses the sheet paper feeding switch 7, which is a step in the normal operation routine NR.
It will wait for the switch operation (103) of step 1 (18th
Figure (h) (a)).

Next, a trouble handling routine TH for dealing with a trouble such as a momentary power outage occurring during execution of the above-described normal operation routine NR will be explained.

That is, in step (100), after turning on the power to each mechanism section C, D, control section F, operation section G, and each sensor 70, 71, etc. of the sheet paper automatic supply toilet seat A, the sheet paper position detection sensor 70 is turned on. If the sheet paper P is detected (IOIY), the next step is to use the movable plate position detection sensor 93 to check whether the movable plate 50 etc. are at the origin position so that the sheet paper P can be removed.
, 93a (116), and if it is not at the home position (116N), the cam movement drive motor 41 is driven (117) according to the operation sequence of the cam movement subroutine SR, and the movable plate 50 is moved as shown in FIG. (
g) Bring the sheet paper to the position where it can be removed (1).
17).

Thereafter, building maintenance personnel, users, etc. remove the unclamped sheet paper P by pulling it out of the functional part casing 15.

As a result, when the sheet paper position detection sensor 70 no longer detects the presence of the sheet paper P in the functional unit casing 15 (118N), the above-mentioned normal operation routine NR
The process moves to step (114), which forms part of the process.

That is, the cam movement drive motor 41 is driven again based on the subroutine SR shown in FIG. 20, the movable plate 50 returns to the original position (114), and the sewage prevention barrier HP provided at the tip of the movable plate 50 As a result, the sheet paper outlet 8a is completely closed, and the sheet paper P is advanced approximately 20,111 degrees toward the toilet seat main body 11 (FIG. 18(h)), and the sheet paper feed switch 71 is operated by the user or the like. (103) will be waited for.

In addition, in the above-mentioned trouble handling routine TR, when replacing the sheet paper roll R, the upper casing 1
7, after turning off the power, attach the sheet paper roll R to the functional part casing 15 with the tip of the sheet paper P sufficiently rewound from the sheet paper outlet 8a to the toilet seat body 11, After that, by attaching the upper casing [7], it is possible to reenergize.

In this case, the sheet paper position detection sensor 70 detects the presence of the sheet paper P in the functional unit casing 15.
is detected (l0IY) and the movable plate 50 is at the origin position (l16Y), step (118) is performed without driving the cam movement drive motor 41 (117).
).

Then, in step (118) as well, the sheet paper position detection sensor 70 detects the sheet paper P (118Y).

Therefore, when the maintenance requirement H presses the sheet paper feeding switch 71 (119) and the seating detection means 72 is off (120Y), the cam movement drive motor 41 is activated according to the operation sequence of the cam movement subroutine SRI. is driven, and the movable play) 50 is moved as shown in FIG. 18(b).
Move to the sheet paper feeding position shown in 121.
), the sheet paper P can be fed out.

After the above cam movement operation is completed, the sheet paper dispensing drive motor 40 is driven according to the operation sequence of the sheet paper dispensing subroutine 5Rffi, and the sheet paper P is dispensed toward the toilet seat body 11, and then the sheet paper P is clamped. After that, it will be broken at the perforation C, and the clamped state will be maintained as it is (1
22).

Then, in the same sheet paper feeding operation (122), the sheet paper feeding subroutine SR, (
If the flag PI (clog) in FIG. 21 is not detected (123N), the routine moves to a cam movement step (112) which is part of the normal operation routine NR.

In the same step (112), the movable play) 50 is
By driving the cam shifting drive motor 41 based on the subroutine SR shown in FIG. 20, the sheet paper is moved to the position where the sheet paper can be removed (FIG. 18(g)), and the movable plate 5o of the sheet paper P and the swing plate are moved. ) 51 is released.

After that, maintenance personnel remove the sheet paper P on the toilet seat body 11.
When the sheet paper P is pulled out and removed, the sheet paper position detection sensor 70 detects that the sheet paper P has been removed, and based on the detection output, the movable plate 50 returns to the original position again as described above (114). , in step (103), the sheet paper P is heated at about 20 am
The sheet paper is fed out (115) and waits for the user to operate the sheet paper feeding switch 71.

Then, in the normal operation routine NR, when the user operates the sheet paper feed switch 71, the sheet paper P is fed onto the toilet seat main body 11 in the above-described order.

Further, in the above step (123), if the flag F1 in the sheet paper feeding subroutine SR of FIG. 21 is detected (123Y), it is determined that a paper jam has occurred, and LI! The abnormality signal generating means such as D is driven to notify the user of this (124a), and the cam movement drive motor 41 is driven according to the operation sequence of the cam movement subroutine SR, and the movable plate 50 is
In order to return to the original position shown in FIG. 18(a) or FIG. 18(h) (124), all control functions of the automatic sheet paper supplying toilet seat A are stopped.

After that, the maintenance personnel removes the upper casing 17 (this removal operation turns off the power switch (not shown) built into the functional part casing 15, ensuring safety), and 3
The sheet paper P stuck in the functional part casing 15 can be removed by swinging the paper sheet 5 forward.

In this removal work, since the movable plate 50 is at the origin position, the movable plate 50 and the suspension support frame 35
The hanging support frame 35 can be easily swung without any interference, and the sheet paper P can be easily removed.

Also, the continuous room operation routine Nl? Even the smell, the step (
107), when flag Fl (paper jam) or flag F2 (paper replenishment) in the sheet paper feeding subroutine SR2 of FIG. 21 is detected (107Y), L
E[1 etc. is driven to notify the user of the abnormality signal generation means (125a), and the cam movement drive motor 41 is driven according to the operation sequence of the cam movement subroutine SR, and the movable plate 50 is driven. , Figure 18 (
a) or return to the original position shown in Fig. 18 (h) and stop all control functions of the automatic sheet paper supply toilet seat A (
125).

After that, the maintenance personnel removes the upper casing 17 (note that this removal operation turns off the power switch (not shown) embedded in the functional part casing 15, as described above, to ensure safety. ), the hanging support frame 35 can be swung forward to remove the sheet paper P stuck in the functional part casing 15, and also to replace the sheet paper roll R.

Even in such sheet paper removal work, since the movable plate 50 is at the origin position, the movable plate 50
The hanging support frame 35 can be easily swung without interference between the hanging support frame 35 and the hanging support frame 35, and the sheet paper P can be easily removed.

Further, in the normal operation routine NR, after the sheet paper P is fed onto the toilet seat body 11 (106), if the fed sheet paper P is unusable for some reason (for example, the sheet paper P is wet). ,
If the sheet paper is twisted and wrinkled or has holes, the user can operate the sheet paper feeding switch 71 again (12N) without sitting down (108N).
6Y), then moves to the cam movement block '5'-7 (112), and such unusable or undesirable sheet paper P can be easily removed (113).
).

Further, as described above, when the sheet paper P is removed (113Y), the sheet paper position detection sensor 70 detects this, and the detection output causes the cam movement drive motor 41 to move as shown in FIG. Subroutine S
R, and drive until it returns to the origin position 114)
, sewage prevention barrier B provided at the tip of the movable plate 50
P completely closes the sheet paper outlet 8a (FIG. 18(h)).

That is, the movable plate 50 can take a position within the functional unit casing 15 that can reliably prevent dirty water from entering the sheet paper delivery path 8 through the sheet paper delivery port 8a.

In addition, after feeding the sheet paper P onto the toilet seat body ll (1
06) If the user, for some reason (e.g.
For a certain period of time (108N) without sitting on the toilet seat main body 11 (108N) and without operating the sheet paper feeding switch 71 (126N),
For example, if 1 minute has passed (127Y), the process immediately moves to the cam movement step (112), and the next user can move the sheet paper P that has been fed out onto the toilet seat body 11.
can be removed (113).

In this case as well, the sheet paper position detection sensor 70 detects that the sheet paper P has been removed, and based on the detection output, the cam movement drive motor 41 is moved to the origin position based on the subroutine SR shown in FIG. 114), the sewage prevention barrier BP provided at the tip of the movable play 50 allows the sheet paper outlet 8a to
is completely closed (Fig. 18(h)).

That is, the movable plate 50 can take a position within the functional unit casing 15 that can reliably prevent dirty water from entering the sheet paper delivery path 8 through the sheet paper delivery port 8a.

Next, the contents of the above-described cam movement subroutine SR and sheet paper delivery subroutine SRt will be explained with reference to FIGS. 20 and 21.

First, the cam movement subroutine SR will be explained with reference to FIG. 20. If the disk cam 44 has already reached the specified cam position (201Y), the normal operation routine NR shown in FIG. Return to the processing routine TH.

On the other hand, if the disc cam 44 has not reached the designated cam position (201N), drive the cam movement drive motor 41 until it reaches the designated cam position (202), and if it has reached the designated cam position (203Y), The cam movement drive motor 41 is stopped (204), and then the routine returns to the regular operation routine NR or troubleshooting routine TR shown in FIG.

In addition, even if the movable plate position detection sensors 93, 93a malfunction or the cam movement drive motor 41 is driven (202), the disc cam 44 may not move to the designated cam even if the set time (for example, 5 seconds) has elapsed. If the position is not reached (20
3N), (205),) It is determined that a trouble has occurred, and the cam movement drive motor 41 is stopped regardless of the position of the disc cam 44 and movable plate 50, and all control functions of the automatic sheet paper supply toilet seat A are disabled. Stop (206).

This can prevent the cam movement drive motor 41 from burning out due to overheating, and
It is possible to prevent wear caused by repeated sliding between the contact surfaces of the movable plate 50 and the swing plate 51.

Next, the sheet paper feeding subroutine SRt will be explained with reference to FIG. 21. By driving the sheet paper feeding drive motor 40 (301), the sheet paper When the position detection sensor 70 detects a through hole (30
3Y), its detection is performed by the sheet paper feeding drive motor 4.
If the set time (for example, 2 seconds) or more has elapsed after the start of the drive of 0, it is determined that the feeding is not finished (304Y), the sheet paper feeding drive motor 40 stops, and the sheet paper P is fed by the feeding roller 33 and the press roller 34. Clamp (305).

Next, drive the cam movement drive motor 41 (306),
The movable plate 50 is connected to the swing plate 51 at 111
When the position for clamping the sheet paper P is reached (30?), the driving of the cam movement drive motor 41 is stopped and the clamping is continued (30B), and then the normal operation routine N1? shown in FIG. 19 is performed. Or return to the trouble handling routine Tll.

In addition, in the sheet paper feeding subroutine SR, the sheet paper feeding drive motor 40 is driven (
301) If about 8 seconds pass without detecting any holes in the sheet paper P (302Y), it is determined that a paper jam has occurred (309), and the flag F1 is turned on and the sheet paper feeder is turned on. The drive of the motor 40 is stopped (305).

On the other hand, even if the sheet paper position detection sensor 70 detects a through hole (303Y), if the same detection occurs within 2 seconds from the start of driving the sheet paper feeding drive motor 40 (304N), the sheet paper It is determined that the sheet paper P in the paper roll R is used up and paper replenishment is necessary (310), and the flag F2 is turned on to stop driving the sheet paper feeding drive motor 40 (310).
05).

When the above-mentioned paper jam or paper replenishment state occurs, the process returns to the normal operation routine NR through operation steps (306), (307), and (308), and flag F1 or flag F2 is detected in operation step (107). (107), the abnormal signal generating means such as an LED is activated to notify the user of the occurrence of the abnormal condition (125a), and the cam movement drive motor 41 is driven based on the subroutine SRI shown in FIG. , to return to the origin position 12
5) The automatic sheet paper supply toilet seat A stops all control functions.

Also, the movable plate position detection sensors 93 and 93a fail, and after the cam movement drive motor 41 is driven (306)
, if the disc cam 44 does not reach the specified cam position even after the set time (for example, 5 seconds) has passed, (307N)
11Y), it is determined that a trouble has occurred, and the drive of the cam movement drive motor 41 is changed to the disk cam 44 and the movable plate 50.
, and all control functions of the automatic sheet paper supplying toilet seat A are stopped (312).

As a result, the sheet paper feeding subroutine SR
Similarly to the cam movement subroutine SR+, in t, it is possible to prevent the cam movement drive motor 41 from being burnt out due to overheating, and also to prevent the contact surfaces of the movable plate 50 and the swing plate 51 from being burnt out. Wear caused by repeated sliding can be prevented.

Furthermore, in this embodiment, the output is turned off when the person leaves the seat after using the toilet, the output is activated when the sheet paper feeding switch 71 is pressed again, or the predetermined period of time has elapsed due to an output when the sheet paper feeding switch 71 is pressed again, or when the user does not sit on the toilet seat main body 11. However, if the seating detection means 72 does not detect the seating, the seat trimmer is turned off.
The side portion can be moved to the sheet paper holding release position where the clamp of the sheet paper P is released and the sheet paper outlet 8a is opened, and the sheet paper P can be easily removed in the sheet paper holding release position. can be removed from the sheet paper outlet 8a and disposed of in the toilet bowl.

After that, when the sheet paper position detection sensor 70 does not detect the sheet paper P due to the removal of the sheet paper P, the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section are set so that the sheet paper outlet 8a is fully opened. At the same time, the clamp of the sheet paper P is released, and by the next operation of the sheet paper feeding spincher 1, the sheet paper P can be returned to the origin position where it can be fed.

Then, at the same origin position, the sheet paper outlet 8
Since a is in a fully closed state, it is possible to reliably prevent sewage from entering the functional unit casing 15.
