Description: BACKGROUND OF THE INVENTION The present invention relates to an apparatus for automatically supplying a fixed length of flushable and disposable sheet paper onto a toilet seat, the object of which is to dispose the toilet seat on the toilet seat. The sheet paper to be hygienically covered is rewound from the sheet paper roll and automatically fed out, and the sheet paper is cut off from the sheet paper roll and sandwiched so that the sheet paper does not slip off from the toilet seat,
It is an object of the present invention to provide a sheet paper automatic supply toilet seat that is capable of automatically releasing the sandwiched state after use and enabling washing and disposal.

(Prior art)

Conventionally, in order to use a sitting-type toilet without sitting directly on the toilet seat arranged on the upper surface of the sitting-type toilet, the opening provided at the location facing the toilet seat of the casing mounted on the rear upper surface of the sitting-type toilet. The sheet paper (having an area enough to cover the toilet seat and having the flexibility of a leaf, hereinafter referred to as a thin leaf body) is drawn out so that the upper surface of the toilet seat is exhausted, and further used. So that the position of the thin leaf does not shift even if
2. Description of the Related Art Thin sheet feeding devices which hold the trailing end of the fed thin sheet (in many cases, sandwich the thin sheet) are generally well known.

It has been found that the performance of the thin-sheet feeding device significantly improves when it is detected that the rear end of the thin-sheet reaches the feed-out port of the casing and that the thin-sheet is removed from the toilet seat. .

That is, the thin-sheet feeding device may be configured to start feeding the thin leaf when receiving a command from the user, and stop feeding when the rear end of the thin leaf reaches the vicinity of the feeding outlet. Further, when the thin body previously fed out is removed from the toilet seat by the user, a feeding preparation operation for feeding out the thin body to the vicinity of the feeding exit in advance in advance for the next feeding is performed. The operation can be started immediately after receiving a command from the user.

For this reason, a sensor for detecting the presence or absence of a thin body near the outlet is provided, and a through hole is provided in the thin body as a detected portion of the sensor, so that the rear end of the thin body reaches the outlet and the thin body is a toilet seat. Has been removed from above.

This measure has the advantage that the structure is simple and easy to manufacture.

[Means for Solving the Invention]

However, in order to accurately detect the rear end of the thin body, it is desirable to provide this through hole at the rear end of the thin body as much as possible. It acts as noise when detecting that it has been removed from. That is, the through hole is detected by a sensor when the thin leaf body whose holding is released is not smoothly removed and returns to the casing side, and the controller receiving this detection result feeds out that the thin leaf body is removed. Preparation operation starts.

In such a case, the thin leaf body that returns to the casing side collides with the thin leaf body that is to be fed out next time, and the thin leaf body that is to be fed out next time bends or curls, thereby causing a paper jam in the exposure opening at the time of feeding out. May occur.

In view of the above problems, an object of the present invention is to provide a thin-sheet feeding device that is optimally designed so that a sensor is not erroneously detected, while maintaining the advantages of a simple structure and easy manufacturing.

[Means for solving the problem]

The present invention provides a feeding means for feeding a thin leaf having a through hole to a toilet seat from a feeding port each time a command is received from a user, and a feeding port provided near the feeding port, and wherein the through hole of the thin leaf is provided. A sensor that outputs the same signal when approaching the outlet and when the thin body is not in the vicinity of the outlet. The sensor is provided at a position where it is not detected by the sensor even if it abuts.

[Action]

According to the thin-sheet feeding device of the present invention, the thin-sheet is automatically fed onto the toilet seat every time a command is received from the user. Further, even when the thin leaf body returns to the feeding means side, since the through hole provided in the thin leaf body is not detected by the sensor, when a signal is output from the sensor, for example,
Just consider the time from receiving the command from the user (this can be done by using the clock circuit originally provided in the microcomputer), and when there is a signal from the sensor, the light transmission This is convenient because it is possible to distinguish whether the user has approached the vicinity or whether there is no thin leaf. Therefore, the present invention can surely avoid erroneous detection by the sensor, while keeping the advantage that the structure is simple and easy to manufacture.

A description will be given of a case where the user feeds out the sheet paper c onto the toilet seat 3 when performing the addition.

12 and 14, the paper feeding switch
When the lamp 40 is turned on, the lamp lighting circuit 57 is energized and the power lamp 41 is turned on. Then, when the paper feeding switch 40 is turned on, the output terminal D of the 4-bit microcomputer LSI is controlled by the control sequence programmed in the 4-bit microcomputer LSI. ₄ becomes "L" level from "H" level, the light emitting diode LE ₂ of the motor drive circuit 56 is turned on, thereby photo-triac Th ₂ is conducting with photocoupler PC ₂ in the oN state and without the AC power of a commercial frequency Is energized to the electric motor 25 to start it (in this case, if the toilet seat 3 is standing up or sitting on the toilet seat 3, the seat detection circuit 54
Since the photosensor PS is in the off state, the electric motor 25 does not start. The same applies when sheet paper remains in the paper detection portion. ). The electric motor 25 causes the disc cam 24 to rotate via the rotation shaft 26, and the movable plate 20 is moved via the driven roller 23 from the state shown in FIG. 6 (the paper feed port 17 is closed) as shown in FIG. The paper feeding port 17 is rotated in the opening direction. When the movable plate 20 is rotated to a state in which the paper feeding port 17 is completely opened as shown in FIG. 3, a pair of detections fixed to the rotation shaft 26 is formed as shown in FIG. The plates 30 and 31 block the light emission of the photodiodes d ₂ and d ₃ of the position detection sensors 28 and 28 a of the movable plate 20, respectively, and output signals from the sensors 28 and 28 a are a 4-bit microcomputer.
Input F of LSI, since it is not input to the F _1, photocoupler PC ₂ is turned off and the output terminal D ₄ is at the "H" level, the electric motor 25
Is stopped, and the movable plate 20 is positioned parallel to the paper delivery path 21 (see 28, 28a, and 25 in FIG. 14). The electric motor 2
When 5 the stop, the control program that is programmed to 4-bit microcontroller, the output terminal D ₄ is intermittently "H" → "L"
→ "H" → "L", and the causes are energized intermittently electric motor 25 to an AC power source, from the output terminal D _4, it outputs a control signal synchronized with the rising edge of the pulse signal output from the half wave zero cross circuit 52 The electric motor 25 is energized with a part of the positive half-wave of the sine wave, whereby the AC power supply intermittently energized to the electric motor 25 is made to be in a state as if an electric current is supplied to the electric motor 25, and the electric motor 25 is energized. Apply braking and stop it suddenly. That is, the electric motor 25 is abruptly stopped in a state where DC braking is applied.This is because when a part of a positive half wave of a sine wave is supplied to the coil, the coil is in a state where DC is supplied. An alternating voltage is generated on the rotor side and an alternating current flows, and this generated power is caused by generating control torque by being consumed as heat (see 25 in FIG. 14). Electric motor
When 25 is stopped, the 4-bit microcomputer LSI output terminal D ₃ immediately "H" level to "L" level and turned to the light emitting diode
LE ₁ is turned, to conduct the photo-triac Th _1, it activates the motor 16 by a photocoupler PC ₁ to the ON state. For this reason, the feeding roller 15 rotates, and the sheet paper c wound around the pressing roller 19 and nipped between the feeding roller 15.
Is unwound from the sheet paper roll 11 and is fed onto the toilet seat 3 via the movable plate 20 → paper feeding port 17. Then, when the through hole 34 perforated in the sheet paper c is detected by the paper detection position detection sensor 33, that is, the light of the photodiode d of the sensor 33 passes through the through hole 34 → the passage 37 to the phototransistor T. Since the detection is not performed, the output signal of the paper detection circuit 53 is not input to the 4-bit microcomputer LSI, whereby the 4-bit microcomputer LSI determines that there is no paper and detects the feeding position (length) of the sheet paper c. . By this detection, 4-bit microcomputer LS
Although about to change to "H" level from the output terminal D ₃ immediately "L" level I, the present invention is an electric motor 16 rotates continue program stored in advance in the control program, the output terminal D ₃ is For a time set in advance by a timer (not shown) built in the 4-bit microcomputer LSI,
The driving of the electric motor 16 is continued while maintaining the “L” level, and the feeding of the sheet paper c is continued. When the set time of the timer has elapsed, the output terminal D ₃ is photocoupler PC ₁ becomes "H" level is turned off, thereby suddenly stop the motor 16 (see 14 Figure 16). The time during which the timer is running is a predetermined length of time from when the sensor 33 detects the through hole 34 of the sheet paper c.
Side, the perforations 35 of the sheet paper c
Is positioned between the breaking protrusion 14 and the feeding roller 15, and the perforation 35 is broken, and the cut end of the broken sheet paper c on the side of the toilet seat 3 is pulled out, so that the broken end is fed out, and the pressing rollers 15, 19 The sheet paper c can be fed out to a position where the through hole 34 is not detected by the paper feeding position detection sensor 33 even when the sheet paper c comes into contact with the holding point. When the electric motor 16 is stopped, as in the case of the electric motor 25, the motor 16 is suddenly stopped with DC braking applied. For this reason, the sheet paper c stops feeding after the through hole 34 moves to the toilet seat 3 side by a predetermined length from the detection point of the sensor 33, that is, the sheet paper c is fed out by a fixed length, and the sheet paper c Cover as shown in FIG. Also, as described above, when the sheet paper c is fed out by a predetermined length even after the through hole 34 of the sheet paper c is detected by the sensor 33, the frequency of the commercial power supply 50
If the / 60Hz is different, the feeding length is also different,
In some cases, it may not be possible to set position 5 as the break location. In consideration of these points, the present invention counts the rising edge of the pulse signal output from the zero-cross detection circuit 52 by a 4-bit microcomputer LSI to determine the frequency, and based on the determined frequency, determines the drive time (transparency) of the electric motor 16. Since the program with the function of controlling the time after the detection of the hole 34 by the timer built in the 4-bit microcomputer LSI is stored in the control program, the perforation provided for one sheet of paper c is stored. 35 can be set to a predetermined breaking position regardless of the frequency.

As described above, the electric motor 16 stops and the sheet paper c
Is extended to cover the toilet seat 3 and the 4-bit microcomputer
Output terminal D ₄ of the LSI becomes immediately "H" level to "L" level, it activates the electric motor 25 by conducting the photocoupler PC ₂ again. For this reason, the movable plate 20 in the cam disc 24
As shown in FIG. 4, from the position shown in the drawing, the sheet paper c that is turned counterclockwise, that is, turned to the turning plate 12 side, and lifts the sheet paper c lying on the paper delivery path 21 to the turning plate 12 side,
As shown in FIG. 4, the rotating plate is held between the pressing piece 22 of the movable plate 20 and the pressing portion 13 of the rotating plate 12.
Continue rotating while pushing 12. As a result, one of the sheet papers c is held between the movable and rotating plates 20 and 12, and the other is fed and held by the pressing rollers 15 and 19. A large tension is applied between the holding points, and the breaking protrusions 14 lightly contact. Then, the disc cam 24 is rotated
Is rotated about half a circle from the start point, that is, as shown in FIG. 10 (C) and FIG. 14, light emission of the movable plate position detection sensor 28 passes through the notch of the detection plate 30. It is received in the phototransistor T _2, conversely, the sensor 28
When a light emission has reached the point that is no longer received is shielded to the detection plate 31 to phototransistor T _3, with the movable plate 20 to the maximum angle inclination as shown in FIG. 6, the rotating plate 12 also movable plate 20 The sheet paper c is further pushed by and is largely rotated clockwise, and the sheet paper c is strongly pressed by the breaking projection 14 of the rotating plate 12 in a state where the maximum tension is applied.
Are sequentially torn from the perforations 35 near the breaking projections 14 and broken as shown in FIG. When the sheet paper c is broken, the electric motor 16 is sequence-controlled by the control program so that the electric motor 16 can be maintained in a state where the DC braking is applied after the feeding of the sheet paper c until the sheet paper c is broken (about 1 second). Since the feed roller 15 can apply tension to the sheet paper c without running idle, the breaking operation can be performed smoothly. At the time of breaking the sheet paper c, the sensor 28 is turned on, the sensor 28a is off, the output terminal D ₄ 4-bit microcomputer LSI turns off the photocoupler PC ₂ is immediately "H" level Motor 25
Is suddenly stopped as described above (see 28, 28a, 16, 25 in FIG. 14). As described above, the detection plates 30 and 31 attached to the pivot 26
As a result, the sensor 28 is turned on, and the sensor 28a is turned off, so that the electric motor 25 does not start, and the broken sheet paper c is moved by the movable and rotating plates 20, 12 as shown in FIG. , So that it does not slide down from the toilet seat 3.

After the sheet paper c is fed out onto the toilet seat 3, the user sits on the toilet seat 3 and makes the punched pieces 36 fall down into the toilet bowl 2 to perform addition. When the user sits on the toilet seat 3, the inside of the photosensor PS of the seating detection circuit 54 is shielded from light by mechanical means and its output signal is not input to the 4-bit microcomputer LSI, so that its output terminals D ₃ and D ₄ are “ H "level. For this reason, the paper feed switch 40
, The electric motors 16 and 25 do not start, and the sheet paper c is not pinched during the addition, or the sheet paper c is unexpectedly fed out to cause a paper jam (No. (See PS, 25, 16 in Fig. 14).

When the user leaves the toilet seat 3 after the addition, the photosensor PS of the seat detection circuit 54 is released from the light-shielded state by the mechanical means, and the output signal from the output end of the photosensor PS is input to the 4-bit microcomputer LSI. And its output end D
₄ immediately "L" level and turned by conducting the photocoupler PC ₂ starts the electric motor 25 (see PS, 25 in FIG. 14). For this reason, the movable plate 20 is rotated clockwise in FIG. 5 from the position shown in FIG. 5, that is, the state where the sheet
Release the pinch. Then, by the rotation of the cam disk 24, the detection plates 30, 31 attached to the rotation shaft 26 are turned to the positions where the movable plate position detection sensors 28, 28a are turned on, as shown in FIG. 10 (D). When moving, the output D ₄ is input to the output signal 4-bit microcontroller LSI from both sensors 28, 28a "H"
Level and is abruptly stops the electric motor 25 turns off the photocoupler PC ₂ (28, 28a in FIG. 14, reference 25). As a result,
As shown in FIG. 3, the rotation of the movable plate 20 is stopped at a position parallel to the paper delivery path 21, as in the case of feeding the sheet paper c. In this state, the sheet paper c is held in the hand and discarded in the toilet 3, or the flushing water is poured and the sheet paper c on the toilet seat 3 is passed through the punched pieces 36 already submerged in the toilet 2. 2 Drag inside and discharge together with sewage. As mentioned above, the movable plate 20 is
When the rotary plate 12 is retracted to the position shown in the figure, the rotation plate 12 is released from the pressing by the movable plate 20, and is automatically returned to a position where it comes into contact with the stopper e by the spring d. When the user leaves the toilet seat 3, the sheet paper c is still held between the rotating and movable plates 12 and 20.
The sheet paper c does not cling to the buttocks.

When the sheet paper c is removed from the seat 3, the output signal of the paper detector 53 is input to the 4-bit microcomputer LSI, activates the electric motor 25 instead of the output terminal D ₄ to "L" level. Therefore, the movable plate 20 is moved by the cam disk 24 from the state shown in FIG. 3 to the paper feeding port 17 as shown in FIG.
In the closing direction, and the closing member h is
When the point at which the shutter 17 is closed is reached, the detection plates 30 and 31 return to their original positions as shown in FIG.
Off the, by turning on the sensors 28a, 4 although the input signal bit microcomputer LSI input terminals F ₁ to the sensor 28a is input, the signal of the sensor 28 is not inputted to the input terminal F, the output terminal D ₄ goes to the “H” level to stop the motor 25 suddenly. For this reason, the paper outlet 17 is closed by the closing member h.
14 to prevent sewage from entering the casing 4 (see 28, 28a, 25 in FIG. 14). When the sensor 28 is movable plate 20 is stopped off and the motor 25 is returned to the original position, by the sensor 28 is off, the 4-bit microcomputer LSI output terminal D ₃ is "L" level and turned by electric motor 16 is activated, and the sheet paper c is advanced to the middle of the movable plate 20 as shown in FIG. In this case, the operation time of the electric motor 16 is set as a timer by a control program. As described above, the sheet paper c is advanced to the movable plate 20 in advance, so that paper jam of the sheet paper c in the casing 4 at the next feeding can be prevented. In this case, since the movable plate 20 is held in a substantially horizontal state in the casing 4 as shown in FIG. 6, the sheet paper c can be smoothly fed out onto the movable plate 20 when it advances.

In addition, when the user stands up from the toilet seat after finishing the addition, when the user's body or clothes touches the sheet paper c on the toilet seat 3 and this is pushed back into the casing 4, the present invention relates to the seat. Even if the broken end of the paper c is fed out and abuts the holding point of the pressing rollers 15 and 19, the through hole 34 of the sheet paper c is detected by being located closer to the paper position detecting sensor 33 (toilet seat 3). The paper is determined to be “absent” by the detection of the through-hole 34, and the movable plate 20 is activated by the activation of the electric motor 25.
Is returned to its original position, and then the feeding end of the next feeding sheet paper fed by the activation of the electric motor 16 and the sheet paper c retracted into the casing 4 come into contact with each other, and the feeding end of the next feeding sheet paper. When the paper is fed out by bending or curling, paper jam does not occur.

Further, when the sheet paper c is not fed out onto the toilet seat 3 within a certain period of time, for example, about 5 seconds after the paper feeding switch 40 is turned on, the through hole 34 of the sheet paper c is connected to the paper feeding position detection sensor 33. In such a case, the output terminal D _{5 of the} 4-bit microcomputer is used.
Becomes "L" level, the paper trouble lamp 42 is lit to indicate that a paper trouble has occurred, and the output terminal
D ₃ is "H" level and becomes suddenly stops the motor 16, and is configured to prevent unwinding of wasted sheet paper c from the sheet paper roll 11.

Furthermore, when the toilet seat 3 is erected, like when seated,
The photosensor PS is operated so as to prevent the feeding of the sheet paper c.

〔The invention's effect〕

Since the present invention is configured as described above, the thin leaf can be automatically fed out onto the toilet seat every time a command is received from the user as needed, and the thin leaf is fed out by any chance. Even in the case of retreating to the means side, since the through hole perforated in the thin body is not detected by the sensor at all, when a signal is output from the sensor, for example, a thin body feeding instruction from the user is received. Only by taking into account the elapsed time, when there is a signal from the sensor, it is easy to discriminate whether the through hole has approached the vicinity of the outlet of the casing or whether there is no thin leaf. As a result, the thin-sheet feeding device of the present invention has a practically excellent effect of being able to reliably avoid erroneous detection of the thin-sheet by the sensor while leaving the advantage that it is easy to manufacture with a simple configuration. It is convenient.
