Abstract

PURPOSE:To block a seat paper surely from being drawn out even if a stool is held while a seat paper is drawn out by controllably driving a roller member according to ON-OFF signals of a seating detecting means. CONSTITUTION:When a stool 3 is held down through a seat paper from above or one is seated on the stool 3 while the seat paper is drawn out, the pivot shaft 61 of a seating detecting means 60 is depressed to lower a sensor activating lever 68 through a lever pressing piece 67 for turning ON a photosensor PS (operating the seating detecting means 60). Thus, a detecting signal of a photocoupler PC is inputted from a seating detecting circuit 54. Then, a photocoupler PC1 is turned OFF to quickly stop a motor 16. Thus, the drawing- out of the seat paper is temporarily stopped. When the stool 3 is released from the depression, the conduction between a photodiode d1 and a photo transistor T1 is secured by a screening plate 72 to turn OFF the photosensor PS as non- conductive one. As a result, the photocoupler PC1 is turned ON to activate the motor 16 and restart the drawing-out of the seat paper.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an apparatus for automatically supplying a fixed length of washable sheet paper onto a toilet seat. The sheet paper to be hygienically covered is unwound from the sheet paper roll and automatically fed out, the sheet paper is separated from the sheet paper roll and the sheet paper is clamped to prevent it from slipping off the toilet seat, and after use, the sheet paper is held in the clamped state. To provide an automatic sheet paper supplying toilet seat which can be automatically unwound and disposed of by washing with water.

[Prior art]

In recent years, for example, a device for laying sheet paper on a toilet seat in consideration of hygiene has been developed, for example, in Utility Model Application No. 60-155399.
The toilet seat cover supply device described in the publication can be seen.

The device has a size and shape that can cover the top surface of the toilet seat, and it winds up a continuous sheet of paper into two rolls and stores it in a protective cover. a paper holder that supports the sheet paper roll so as to be able to continuously feed it; a feed roller device that feeds the sheet paper fed out from the sheet paper roll forward by a predetermined length near the top surface of the toilet seat; A cutting device equipped with a cutting blade that cuts the rear end of the sheet paper fed out a predetermined amount onto the toilet seat.

In such a conventional device, the sheet paper feeding and cutting operations are such that when the operating switch is turned on, the sheet paper is sequentially fed out onto the toilet seat by a feeding roller device, and the sheet paper is fed out onto the toilet seat for a fixed length at each position. For example, when a hole in the sheet paper is detected by a paper feed position detection sensor that detects the position in a charging manner, the feed roller device is driven and controlled to deposit a fixed amount of sheet paper onto the toilet seat. The paper is automatically fed out to the desired length, and then the cutting blade is raised and lowered to cut the sheet paper.After this, the user sits on the toilet seat through the sheet paper and refills the toilet. The user discharges the spread sheet paper into the toilet bowl and disposes of it by flushing.

In this way, when using a Western-style toilet bowl, the sheet paper can be automatically spread on the toilet seat and the user can sit on it, making it very convenient and hygienic to use the Western-style toilet bowl.

[Means for the invention to solve the problem]

However, in the toilet seat cover supply device having the above configuration,
When automatically feeding and laying sheet paper on the toilet seat,
There were the following problems.

(1) The sheet paper that is fed out long enough to cover the toilet seat is large and is made of soft, thin sheets, so it is very stiff. Therefore, if you accidentally or intentionally press the sheet paper against the toilet seat while the sheet paper is being fed out, the feeding roller device will be driven open to feed out the sheet paper a fixed length onto the toilet seat. The sheet paper fed out by the roller device may bend like an accordion between the point where it stops sliding on the toilet seat and the feeding roller device, causing the paper to jam inside the mounting base, or A portion of the sheet paper that has become knotted within the mounting base may wrap around the roller portion of the feed-out roller device, causing the feed-out roller device to lock. In this case, if an action is taken to prevent sheet paper from being fed out immediately after it has been fed out from the mounting base, most of the sheet paper will become tangled within the mounting base because most of the sheet paper has not been fed out onto the toilet seat. If the sheet paper gets tangled within the mounting base or wraps around the feeding roller device as described above, remove the mounting base and remove the tangled paper within the base. The sheet paper wrapped around the roller must be removed by removing the sheet paper or manually rotating the feeding roller device.
There was a problem that maintenance work required time and effort.

(2) Furthermore, in the above-mentioned toilet seat cover supply device, since there is no seating detection means for detecting when the user sits on the toilet seat, after the user sits on the toilet seat,
If the operation switch for sheet paper feeding was turned on by mistake, the sheet paper would be fed out, which could cause a paper jam. For this reason, for example, an infrared sensor for detecting the movement of a user seated on the toilet seat may be provided at an arbitrary location such as the inner surface of the toilet seat or the mounting base to detect that the user is sitting on the toilet seat. However, in this case, if the user's sitting position on the toilet seat is different, for example, if the user deviates from the sitting position and sits on the front side of the toilet seat or at an angle, this will not be detected even when the user sits down or leaves the seat. As a result, there is a problem in that sheet paper is fed out by erroneously operating the operation switch.

In view of the above-mentioned problems, the present invention mechanically connects to the pivot portion of the toilet seat a seating detection means that detects whether the user is sitting or leaving the seat and outputs a detection signal, and when the sheet paper is being fed out. For example, when a toilet seat is pressed down from above the sheet paper that has been fed out, the sitting detection means operates to stop feeding out the sheet paper, and when the pressing means is released, the sheet paper is fed out again. To provide an automatic sheet paper supplying toilet seat which smoothly dispenses sheet paper.

[Means to solve the problem]

The present invention includes a casing to which a sheet paper roll is rotatably attached, a roll member for sandwiching the sheet paper rewound from the sheet paper roll and delivering it to a fixed length onto a toilet seat, and a roll member for feeding out a fixed length of sheet paper onto a toilet seat. a movable plate that slides and guides the movable plate; and a movable plate that is disposed above the movable plate to sandwich the sheet paper between the movable plate and has a break protrusion facing downward on the opposite side of the sandwiched portion. A rotating plate, further comprising:
The rear part of the toilet seat is attached to the front side of the casing using a pivot so that it can be rotated up and down in the vertical direction, and this pivot is further provided with a detection signal for detecting when a user sits on or leaves the toilet seat body. An automatic sheet paper supplying toilet seat is constructed by a paper feeding/breaking device which is provided with a occupancy detecting means that outputs occupancy detection means, and a drive control device having a built-in control program for driving and controlling this paper feeding/breaking device. ,
Its action is as follows.

[For production]

To feed sheet paper onto the toilet seat, the movable plate of the paper feeding/breaking device and the roller member are moved to the paper feeding position using a command signal from the drive control device, and in this state, the roller member is moved to the paper feeding position. The member is driven to feed out the sheet paper a fixed length, and then the movable plate is moved in a direction that applies tension to the sheet paper, and the sheet paper is held between the rotary plate and the roller member. A large amount of tension is applied to break the perforation of the sheet paper, and after the breakage, the paper is held between the movable plate and the rotating plate to prevent the sheet paper from slipping off the toilet seat, and after the sheet paper is used up. The movable plate is automatically returned to its original position, the sheet paper is removed, and the paper feeding port is closed. After this, the sheet paper is placed on the movable plate a predetermined length in preparation for the next feeding. The sheet paper is fed out for one time by advancing the sheet paper up to the point where the sheet paper is fed out.
The paper feeding/breaking device is all driven and controlled by a control program built into the drive control device, and if the user accidentally sits on the toilet seat before feeding out the sheet paper, or if the toilet seat is raised, , when a person sits on the toilet seat after feeding out the paper, this is detected by the seating detection means provided on the toilet seat, and while the detection signal is being outputted, the electric motor that drives the roller member for feeding out the sheet paper is driven. If an output signal is not sent out, or if someone sits on the toilet seat as described above, including mischievously, while the sheet paper is being fed out, or if the toilet seat is pressed down from above the sheet paper that is being fed out, the sitting detection When the means detects this and suddenly brakes the electric motor to stop it, stops feeding the sheet paper, the pressure on the toilet seat is released, and the detection signal from the seating detection means is no longer output. By starting the electric motor again and feeding out the remaining sheet paper, it is possible to eliminate the clogging phenomenon that occurs when the sheet paper is obstructed by sudden feeding or mischief during feeding. By simplifying maintenance work and smoothing sheet paper feeding work,
This type of toilet seat is characterized by significantly improved reliability.

Stop suddenly. In other words, the motor 25 suddenly stops under DC braking. This is because when the coil is energized with part of the positive half wave of the sine wave, the coil is energized with DC. This is due to the fact that alternating current voltage is generated on the rotor side, alternating current flows, and this generated power is consumed as heat, thereby generating braking torque (see 25 in Figure 18).
), when the electric motor 25 stops, the 4-bit microcomputer L
SI output end.

immediately changes from the "H" level to the "L" level, the light emitting diode LE lights up, the phototriac Th is made conductive, the photocoupler PC is turned on, and the electric motor 16 is started. Therefore, the feed roller 15 rotates, and the sheet paper C, which is wound around the pressure roller 19 and held between the feed roller 15, is transferred to the sheet paper roll 11.
While unwinding from the movable plate 20 → paper feeding port 1
7 and then onto the toilet seat 3. And sheet paper C
A through hole 34 bored in the paper feed position detection sensor 33
That is, the light from the photodiode d of the sensor 33 passes through the through hole 34 → the passage port 37 and is not detected by the phototransistor T.
The output signal of the 4-bit microcomputer LSI is not input to the 4-bit microcomputer LSI, and as a result, the 4-bit microcomputer LSI
Based on this judgment, the feeding position (length) of sheet paper C is detected. Due to this detection, the output end of the 4-bit microcomputer LSI immediately tries to change from the "L" level to the "H" level, but the present invention continues to rotate the electric motor 16, which is stored in advance in the control program 5. Depending on the program, the output end will last for a preset time using a timer (not shown) built into the 4-bit microcontroller LSI.
The electric motor 16 continues to be driven while maintaining the "L" level to continue feeding the sheet paper C. Then, when the set time of the timer has elapsed, the output end reaches °゛H.
When the ``H'' level is reached, the photocoupler PC turns off, and the electric 811
6 to 2. (See X1 at 16 in FIG. 18). Note that the time period during which the timer is in operation is determined when the sewing machine for the sheet paper C moves by a preset length from the time when the through hole 34 of the sheet paper C is detected by the sensor 33 to the toilet seat 3 side. The opening 35 is located between the breaking protrusion 14 and the feeding roller 15, and when the perforation 35 is broken and the broken sheet paper C of the three examples of toilet seats retreats, the broken end is fed out and the pressing roller 15 ，
The sheet paper C is set so that 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 if the sheet paper C comes into contact with the nipping point 19 . And the electric 4! ! When the motor 16 is stopped, like the electric motor 25, it is abruptly stopped with DC braking applied. For this reason, the sheet paper C is stopped feeding after the through hole 34 has moved toward the toilet seat 3 by a predetermined length from the detection point of the sensor 33. In other words, the sheet paper C is fed out a fixed length and moved toward the toilet seat 3 by a predetermined length from the detection point of the sensor 33.
Cover the top as shown in Figure 1. Further, as described above, when the sheet paper C is fed out by a predetermined length even after the sensor 33 detects the through hole 34 of the sheet paper C, if the frequency of the commercial power source is different from ¥1.50/60Hz, The length of the feed is also different, and it may become impossible to set the position of the perforation 35 as the breaking point.8 The present invention takes these points into account, and controls the rise of the pulse signal output from the zero-cross detection circuit 52 using a 4-bit microcomputer LSI. A function to count and determine the frequency, and control the driving time of the motor 16 (referring to the time after i! i hole 34 detection) based on the determined frequency using a timer built into the 4-bit microcontroller LSI. Since the program with the following is stored in the control program, the perforations 35 provided in the C-sheet paper are as follows.
It is possible to set a predetermined breaking position regardless of the frequency.

In addition, during the feeding of the sheet paper C, the toilet seat 3 may be pressed down from above the sheet paper C, or the toilet seat 3 may be
When a person is seated on the seat, the pivot shaft 61 of the seating detection means 60 is pushed down, and the elevating shaft 64 interlocked with this moves down against the force of the coil spring 65, and the lever pressing piece 67 pushes the sensor activation lever 68 is lowered, and the photosensor PS is turned on (the seating detection means 60 is operated).
A detection signal from the photocoupler PS is input from the seating detection circuit 54 to the input terminal D2 of the 4-pin microcomputer LSI. In this case, the 4-bit microcomputer LSI has an output terminal D=,
Since the control program that immediately changes D4 from "L" level to "°H" level is built in, the photocoupler P
C, is turned off and the electric motor 16 is brought to a sudden stop. For this reason,
Feeding of sheet paper C is temporarily stopped (18th
(see Y in FIG. 60 and Yl in 16), in this case, the electric motor 16
Since the sheet paper C is designed to suddenly stop under direct current braking, although the sheet paper C may be slightly bent within the vapor delivery path 21, it will not become entangled or clogged. When the pressure on the toilet seat 3 is released (or when the toilet seat 3 is removed), the pivot shaft 61 rises to a position where it comes into contact with the regulation plate 66 due to the force of the coil spring 65, as shown in FIG. The activation lever 68 is returned to its original position, and the shielding plate 72 is used to shield the photodiode d and the phototransistor T, making them non-conductive and turning off the photosensor PS. As a result, the signal from the seating detection circuit 54 is no longer input to the input terminal D2 of the 4-bit microcomputer LSI (the operation of the seating detection means 60 is canceled). Therefore, the output terminal D3 of the 4-bit microphone LSI immediately changes from the "H" level to the "L" level, turns on the photocoupler PC3, starts the electric motor 16, and restarts the feeding of the sheet paper C. At this time, the sheet paper C Since no clogging occurs in the paper delivery path 21, the paper can be smoothly delivered from the paper delivery port 17.Also, while the sheet paper C is being delivered,
Even when the toilet seat 3 is suddenly raised, the seating detection means 60 operates to stop the first extension and return the toilet seat 3 to its current position, allowing it to be extended again. After refeeding the sheet paper C, when the toilet seat 3 is moved again and the seating detection means 60 is operated, the same as above occurs.
Feeding is stopped (Z in FIG. 18, 60).

(See 21 of 16). While feeding out the sheet paper C,
When the seating detection means 60 is activated by moving the toilet seat 3, or when the operation is canceled, the first
As described in the flow sheet shown in FIG. 7, the program for driving and controlling the electric motor 1116 is incorporated into the control program, so even if the toilet seat 3 is moved while the sheet paper C is being fed out, the driving control of the electric motor 16 will not be performed. Since this can be reliably performed by the control program, paper jams will not occur at all.

As mentioned above, the electric motor 16 stops and the sheet paper C
When it is extended to a length that covers the toilet seat 3, the output terminal D4 of the 4-bit microcomputer LSI immediately changes from the "H" level to the "L" level, making the photocoupler PC7 conductive again and causing the electric [
Start 25.

Therefore, the movable plate 20 in the cam disk 24 is
From the position shown in the figure, the sheet paper C is rotated counterclockwise, that is, toward the rotating plate 12 side as shown in FIG. As shown in the figure, the pressing piece 22 of the movable plate 20
The rotating plate 12 is held between the rotating plate 1-12 and the pressing part 13 of the rotating plate 1-12, and the rotating plate 12 continues to rotate without being pushed.

As a result, one side of the sheet paper C is held between the movable and rotating plates 20.12, and the other side is fed out.

As the movable plate 20 rotates while being held between the pressing rollers 15 and 19, a large tension is applied between the two holding points, and the breaking protrusion 14 comes into light contact. When the disc cam 24 rotates about half a turn from its starting point due to the rotation of the rotation shaft 26, the movable plate position detection sensor 28 moves as shown in FIGS. 10(C) and 14. The emitted light passes through the notch of the detection plate 30 and is received by the phototransistor T8, and conversely, the sensor 28
The light emitted from the phototransistor T is blocked by the detection plate 31.
, when the movable plate 20 reaches the point where no light is received, the movable plate 20 tilts at the maximum angle as shown in FIG.
The rotating plate 12 is further pushed by the movable plate 20 and rotates significantly clockwise, and the sheet paper C is
With the maximum tension applied, the sheet paper C is strongly pressed by the breaking protrusion 14 of the rotating plate 12, so that the sheet paper C is sequentially torn from the perforation 35 near the breaking protrusion 14 and is broken as shown in FIG. Ru.

When the sheet paper C is broken, the electric motor 16 is sequence-controlled by a control program so that it can be maintained in a DC braking state from the time the sheet paper C is fed until it is broken (about 1 second). Therefore, the feeding roller 15 does not idle (because tension can be applied to the sheet paper C, the tearing operation can be carried out smoothly).

When this sheet paper C is torn, the sensor 28
is on and the sensor 28a is off, the output terminal D4 of the 4-bit microcomputer LSI immediately goes to H'' level, turns off the photocoupler Pc2, and suddenly stops the electric motor 25 as described above (28 in FIG. 18). , 28a, 16.25).As mentioned above, the detection plate 30 attached to the rotation shaft 26
．． Since the sensor 28 is turned on and the sensor 28a is turned off by 31, the electric motor 8!25 is not activated, and the broken sheet paper C is transferred to both movable two-turn plates as shown in FIG. ) 20.12, so it will not slip off 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 relieves himself by hanging the punched piece 36 into the toilet bowl 2. When the user sits on the toilet seat 3, the seating is detected. The shielding M plate 72 of the means 6o releases the conduction shielding between the photodiode d1 and the phototransistor TI to turn on the photosensor PS, and the detection signal is input from the seating detection circuit 54 to the 4-bit microcomputer LSI, so that its output is The end DD4 is at "H" level F. Therefore, even if the paper feed switch 40 is turned on by mistake while the user is seated, the electric motor 16.25 will not start, and the sheet paper C may become unclipped or the sheet paper C may be unexpectedly fed while the user is using the errand. It will not cause paper jams (No. 1)
(See Figure 8 PS, 25.16).

When the user leaves the toilet seat 3 after relieving himself or herself, the lifting shaft 64 of the seating detection means 60 is raised by the force of the coil spring 65, and the sensor activation lever 68 is moved between the photodiode d and the phototransistor T. The photo sensor PS is turned off by blocking light.

Therefore, the detection signal from the seating detection circuit 54 is not input to the 4-bit microcomputer LSI, and its output terminal D4 immediately changes from the "H" level to the "L" level, and the photocoupler PC
, to start the electric motor 25 (60. in FIG. 18).
25), therefore, the rotation of the cam disk 24 moves the movable plate 20 to the position shown in FIG. 5, that is, the sheet paper C.
The sheet paper C is rotated clockwise in FIG. Then, due to the rotation of the cam disk 24, the detection [30,
When the movable plate position detection sensor 28, 28a is turned on as shown in FIG. 10(D), the output signals from both sensors 28 and 28a are input to the 4-bit microcomputer LSI and The output terminal D4 becomes "H" level, turning off the photocoupler PC and turning off the electric motor 25.
(See 28.28a and 25 in Figure 18)
. As a result, as shown in FIG. 3, the movable play plate 20 stops rotating at a position parallel to the paper delivery path 21, similar to when the sheet paper C is delivered. In this state, either hold the sheet paper C in your hand and throw it away into the toilet bowl 3, or run the flushing water to remove the punched piece 3 that is already submerged in the toilet bowl 2.
The sheet paper C on the toilet seat 3 is dragged into the interior of the toilet bowl 2 via the toilet seat 3 and discharged together with the dirty water. As described above, when the movable plate 20 retreats to the position shown in FIG. 3, the rotation plate 12 is no longer pressed by the movable plate 2o, and therefore automatically returns to the position where it contacts the stopper e by the spring d. Also, when the user leaves the toilet seat 3,
Sheet paper C is still rotating and movable (both play) L2,2
0, the sheet paper C does not wrap around the buttocks.

When the sheet paper C is removed from the toilet seat 3, the output signal of the paper detection circuit 53 is input to the 4-bit microcomputer LSI, and the output terminal is changed to "L" level and the electric 12
Start 5. Therefore, the movable plate 20 is rotated by the cam disk 24 from the state shown in FIG. 3 in the direction of closing the paper feeding port 17 as shown in FIG. 6, and the closing member closes the paper feeding port 17. Upon reaching the point, the detection plates 30 and 31 return to their original positions as shown in FIG. Edge F
Although the human power signal from the sensor 28a is input to the input terminal F, the signal from the sensor 28 is not input to the input terminal F, so the output terminal D4 becomes "H" level and the electric motor 25 is suddenly stopped. Therefore, the paper outlet 17 is reliably closed by the closing member to prevent dirty water from entering the casing 4 (see 28, 28a and 25 in FIG. 18), the sensor 28 is turned off, and the electric motor 25 is When the movable plate 20 returns to its original position, the sensor 2B is off, so the output terminal D3 of the 4-bit microcontroller LSI becomes "
L" level, the electric motor 16 is started and the sheet paper C is advanced to the middle of the movable plate 2o as shown in FIG. .in this way,
By advancing the sheet paper C up to the top of the movable plate 20 in advance, it is possible to prevent the sheet paper C from jamming inside the casing 4 during the next feeding. In this case, since the movable plate 20 is held in a substantially horizontal state within the casing 4 as shown in FIG. 6, the sheet paper C can be smoothly fed onto the movable plate 20 when advancing.

Furthermore, when the user stands up from the toilet seat after relieving himself/herself,
When the user's body or clothes touch the sheet paper C on the toilet seat 3 and this is pushed back into the casing 4,
Even if the broken end of the sheet paper C contacts the nipping point of both the feeding and pressing rollers 15 and 19, the sheet paper C
The through hole 34 is located in front of the paper position detection sensor 33 (
Since it is located on the toilet seat 3) side so that it is not detected, it is determined that there is no paper r by the detection of the through hole 34, and after returning the movable plate 20 to its original position by starting the electric motor 25, the electric motor The feeding end of the sheet paper for the next feeding, which is fed out by the activation of 16, and the sheet paper C that has retreated into the casing 4 contact each other, and the feeding end of the sheet paper for the next feeding is bent or curled. When it is fed out, it does not cause paper jams.

Also, even if a certain period of time, for example, about 5 seconds has passed since the paper feeding switch 40 was turned on, the sheet paper C does not reach the toilet seat 3.
When the sheet paper C is not fed upward, the through hole 34 of the sheet paper C
This is because the paper feed position detection sensor 33 does not detect the paper feed position. In such a case, the output end of the 4-bit microcomputer becomes "L" level, lighting up the trouble lamp 42 and indicating that a paper trouble has occurred. is displayed, and the output end becomes "H" level to suddenly stop the electric motor 16, thereby preventing wasteful rewinding of the sheet paper C from the sheet paper roll 11.

〔Effect of the invention〕

Since the present invention is configured as described above, it has the following effects.

(1) The present invention detects when a sitting or unseating operation is performed on the pivot portion of the toilet seat, which is attached to the casing of the automatic sheet paper supply toilet seat so as to be able to pivot freely, and outputs a detection signal. A driving control device is provided with a seating detection means for outputting an output, and when the seating detection means is turned on or off, the driving control device controls the drive of an electric motor that drives a roller member based on the on/off signal. There is a control program that stops the electric motor when the machine is turned off, and restarts the electric motor when it is turned off. When the toilet seat is operated, the seating detection means is turned on and prevents the sheet paper from being fed out, and when the seating detection means is turned off, the sheet paper can be fed out. Even if the toilet seat is moved inadvertently, it is possible to reliably prevent the sheet paper from being fed out, and it is possible to eliminate clogging of the sheet paper while it is being fed out.

(2) Furthermore, when the feeding of the sheet paper is stopped due to the ON operation of the seating detection means, the electric motor that drives the roller member is suddenly braked and stops suddenly, so that the sheet paper is almost deflected inside the casing. Therefore, when the paper is fed out again, the paper can be fed out smoothly without jamming or wrinkles. Further, since only paper jams occur when feeding the paper again, there is an advantage that maintenance work for clearing paper jams can be reduced.
