Upper casing 17
Is a semicircular ceiling plate 24 as shown in FIGS.
And left and right side walls 25, 26 and front and rear walls 27, which are suspended from the periphery thereof,
28 and is formed.

As shown in FIG. 3, the inner structure of the lower casing 16 is provided with bearing boxes 30 and 31 on the left and right sides of the lower casing 16, respectively. A feeding DC motor 40 and a cam driving motor 41, which are driving sources of the cutting mechanism D, are provided.

As shown in FIGS. 3 to 7, the feeding mechanism C horizontally extends a feeding shaft 32 connected to a feeding motor 40 between upper left and right bearing boxes 30, 31 of the lower casing 16. A feed roller 33 is fixed to the feed shaft 32, and cooperates with a driven roller 34 disposed above the feed roller 33 to press and clamp the sheet paper P, and to transfer the sheet paper P from the roll storage portion E to the toilet seat. It is extended on the main body 11. The feed roller 33 has one end connected to the feed motor 40, and therefore does not perform reverse rotation due to vibration.

Reference numeral 56 denotes a pressing piece 56 provided at the rear of the upper surface of the movable plate 50. The pressing piece 56 can clamp the sheet paper P in cooperation with a pressing piece 57 forming the front of the swinging plate 51. Further, a cutting portion 58 integral with the pressing piece 57 is formed at a rear portion of the swing plate 51.

With such a configuration, the cam driving motor 41
When the power transmission shaft 43 is rotated, the disc cam 44 rotates,
The movable plate 50 swings about the pivot 49, and the swing plate 51 swings in conjunction therewith, so that the cutting section 58 can press and cut the sheet paper P. In addition,
BP is a sewage intrusion prevention barrier attached to the upper front part of the movable plate 50.

As shown in FIGS. 6 to 10, the roll storage section E is provided with roll holders 60 and 61 in the left and right bearing boxes 30 and 31, respectively, and wraps the sheet paper P around the paper tube R1 in a multiplex manner. The sheet paper roll R formed by being rotated is supported so as to be exchangeable, and the pivot support portion of the sheet paper roll R is provided with a vibration rotation preventing means K2. That is, a plurality of ridges 60a are formed on the outer periphery of the roll holder 60 and are engaged with the cutout grooves R2 formed at the end of the paper tube R1, so that the holder 60 and the sheet paper roll R are integrally rotated. It works or stops. 62 is a holder mounting cylinder that rotatably supports the holder 60, 63 is a spring that presses the holder mounting cylinder 62 in the direction of the paper tube R1, and a body 64a of an electromagnetic brake 64 is fixed to the holder mounting cylinder 62, Same adsorption piece
64b is fixed to the outer surface of the roll holder 60. The electromagnetic brake 64 is energized when the feeding motor 40 is operated, and the energization causes the suction piece 64b to be suction-fixed to the main body 64a side, so that the roll holder, and eventually the sheet paper roll R, can rotate freely. The feeding of the sheet paper P becomes possible. When the feeding motor 40 is not operated, that is, when the feeding of the sheet paper P is not performed, the power supply to the electromagnetic brake 64 is turned off.
By the suction piece 64b being pressed and fixed to the roll holder 60 by the spring 63, the rotation of the sheet paper roll R due to vibration is prevented, and the sheet paper P extending from the roll R is prevented from returning and loosening. Paper P
Can be held accurately.

As shown in FIGS. 3 to 5, the operation unit G is provided above the right front portion of the lower casing 16, and includes a feed switch 71, a power lamp including a light emitting diode, a paper jam, and a paper jam. It is constituted by a display unit g1 such as a paper trouble lamp having an alarm function when an abnormality such as replenishment occurs.

Below the operation section G, as shown in FIGS. 2 and 4, a battery case 15a capable of accommodating four D1 batteries S1.
Is formed integrally with the lower casing 16, and the case 15
The electric power for driving each of the mechanism units C and D and the control unit F is supplied from the battery S1 in a. 15b is a cover that can be freely opened and closed.

At the front right position of the functional casing 15,
As shown in FIG. 14, a position detecting sensor 70 is provided. The position detecting sensor 70 includes a phototransistor and a photodiode. When the sheet paper P is fed out onto the main body 11, the position detection sensor 70 detects the position detection through-hole b formed in the sheet paper P, and stops the operation of the feeding mechanism C, thereby accurately feeding the sheet paper P. It can be supplied on the toilet seat body 11. L1,
L2 is a lead wire.

As shown in FIGS. 3 and 15 to 18, the seating detecting means 72 connects the opposite ends of the rear portion of the toilet seat main body 11 through the functional pivot 13 and the simple pivot 13a to both sides of the front portion of the functional casing 15. It is attached to the pivotal supports 15a and 15b provided on the toilet seat so as to be detachable and rotatable so as to detect the presence or absence of seating by a load applied to the toilet seat body 11, and is disposed in the pivotal support 15a and attached to the functional pivot 13. Linked and linked.

The function axis 13 is, as shown in FIGS.
It is inserted into the pivot support 15a through an elongated hole 75 provided vertically in the inner side wall 74 of the pivot support 15a, and is rotated by a movable bearing 77 disposed in the lift guide casing 76 so as to be able to move up and down. It is pivoted freely. The movable bearing 77 is always urged upward by the coil spring 78, but its upper limit position is regulated by the regulating plate 79. Therefore, normally, the movable bearing 77 takes the upper position (unseated) shown in FIG. The functional pivot 13 and the toilet seat main body 11 also assume the upper positions shown in FIG. The functional pivot 13 has a substantially arc-shaped lever pressing piece 80 protruding from the insertion end thereof, and a sensor activation lever 81 disposed below the lever pressing piece 80.
81 is supported so that the base end portion 81a can move up and down inside.
The upper surface of the sensor activation lever 81 is constantly urged upward by the coil spring 82 to constantly contact the lever pressing piece 80. 83 is a lever elevating guide casing, 84 is a shielding plate protruding from the tip 81b of the sensor activation lever 81, and is a light projecting element 85a and a light receiving element of the infrared sensor 85 disposed in the pivotal support 15a of the functional casing 15. 85b.

A toilet seat body engaging portion 86 having a flat cross-sectional shape is formed on the side of the functional pivot 13 opposite to the toilet seat body 11 and is fitted into the pivot engaging hole 87 so as not to rotate. The upright (falling down) of 11 causes the functional pivot 13 and the lever pressing piece 80 to rotate, and the functional pivot 13, the movable bearing 77, the lever pressing piece 80, and the sensor activation lever 81 (by) against the urging force of the coil spring 78. Goes down (ascends) and the shielding plate 84 is the light emitting element
Since the connection between 85a and the light receiving element 85b is conducted, the infrared sensor 85
Is turned on (off), the posture of the toilet seat main body 11 can be detected.
When the feed switch 11 is in the upright state, the operation of the feed mechanism C is suppressed even if the feed switch 71 is pressed, and
It is possible to prevent the sheet paper P from becoming entangled or clogged in 15.

The movable plate position detection sensors 93 and 93a are:
As shown in FIGS. 18 and 19, a photointerceptor type including a light emitting element, a light receiving element, and a pair of detection plates 96 and 96a is provided. As shown in FIGS. Are housed in a sensor mounting box 95 provided on the bottom surface of the casing 94 near the center of the box.

As shown in FIGS. 19 and 20, the detection plates 96 and 96a are formed in an arc shape with approximately one-third notches g-1, h-1 as shown in FIG. In the superimposed state, the notch g-1, h-1 has a notch angle θ of about 50 degrees, so that its mounting position on the power transmission shaft 43 is shifted in the circumferential direction,
By detecting the rotation position of the movable plate 50 based on the output of the light receiving element, the movable plate is moved to each of the operation positions (a to h) shown in the explanatory diagram (FIG. 22) showing the operation sequence of the sheet paper automatic supply toilet seat A described later. It is possible to detect that 50 has come and to cause the feeding mechanism C or the like to perform a desired operation.

The sheet paper P is, as shown in FIG.
A linear perforation c for cutting is provided in the width direction at a predetermined interval in the feeding direction, and a cutout perforation a having a shape adapted to the inner shape of the toilet seat body 11 is provided between each perforation c.
However, when a non-perforated portion d is formed between both ends of the rear portion of the cutout perforation a, and the cutout perforation a is cut, the central portion hangs down in the flush toilet 10. Further, on one side edge of the sheet paper P, through holes b for position detection are provided at regular intervals in the longitudinal direction.
The last sheet of paper P1 wound in the above is provided with a perforation b1 for detecting the paper breakage, and when this is detected by the position detection sensor 70, the paper trouble lamp LED2 is turned on. I have.

Next, the use operation of the sheet paper automatic supply toilet seat having the above configuration will be described with reference to the operation sequence explanatory diagram shown in FIG. 22 and the flowcharts shown in FIGS.
This will be described in detail.

FIG. 23 shows the initial operation, that is, the case where the battery S1 is housed in the battery case 15a. When the battery is housed in the case 15a, it is determined in step 401 whether or not the battery operates normally. In this case, the battery exhaustion LED 1 is turned on for about 0.5 seconds, and the process proceeds from step 402 to step 403. LE if abnormal
Since D1 does not light up, the process shifts to step 404 to urge replacement of the battery. If the movable plate 50 is in the normal position in step 403, the process enters the standby state in step 405.If the movable plate 50 is not in the normal position, the process proceeds to step 406 to return the movable plate 50 to the origin position. Then, if "Yes", the process proceeds to step 405, and if "No", the process proceeds to A in the normal operation. When the feeding switch 71 is pressed in step 408 in the state of step 405, the flow shifts from step 409 to 410. If the toilet seat 11 is standing up at the stage of step 410, the microcomputer of the control unit F activates the toilet seat 11 to activate the seating sensor 72, the mode is switched from the paper feed mode to the maintenance mode, and the process proceeds to step 411, where the paper If clogging or the like occurs, LED2 and the like are turned on. Toilet seat at step 410
If 11 falls on the toilet 10, the process proceeds to step 412. If the battery is exhausted, the process proceeds to step 413, and the LED 1 is turned on for 5 seconds to give notice of the battery exhaustion.

If the battery is not exhausted, the flow shifts to step 414. In the case of Y, the flow shifts to the point D of the normal operation, and in the case of N, the flow shifts to the point B.

The paper feeding point in step 414 means a state in which the movable plate 50 feeds the sheet paper P in a horizontal state, that is, a state in which the paper feeding port 8a is opened.

FIGS. 24 to 25 show a normal operation. When the feed switch 71 is pressed in step 415, steps 416 and
The process proceeds to step 417, and if the toilet seat 11 is standing up in step 417, the control unit F is switched to the maintenance mode. If it is determined that the toilet seat 11 is not standing up, the control unit F determines in step 418 whether to replenish the paper.

When the position detecting sensor detects the paper end position detecting hole X of the sheet paper P as shown in FIG. 25, it is determined that paper replenishment is necessary. Lights to indicate that a paper problem (paper replenishment) has occurred.

On the other hand, if it is determined that paper replenishment is not necessary, the flow proceeds to step 421 for paper presence, and if it is determined that paper is present (in this case, it indicates that paper remains on the position detection sensor), Move to the standby state without paper feed, and
If it is determined in 421 that there is no paper, step 423 → 424
→ Move to 428.

If it is determined in step 423 that the battery is exhausted, the process proceeds to step 426, in which LED1 is turned on for 5 seconds to notify the user that the battery is exhausted. If determined, step 424 →
Go to step 428, and if the battery is
The process proceeds to step 427, in which the LED1 is continuously lit in step 427-1.If the LED1 is lit continuously, it means that the battery has reached the end of its life. Is not driven, and the sheet paper P is not fed out. (Note that the battery exhaustion notice indicates a case where the voltage is detected to be 4.5 V by the control unit F (microcomputer).
When the life of the battery has expired, it indicates that 4 V has been detected, and these are all programmed in the microcomputer.)

The step 424 "movable plate 5"
“0” trouble indicates trouble of the motor M2 and the movable plate position detection sensor, and “Y” indicates that the movable plate 50
The sheet paper P is not fed out so that does not operate, and the processing shifts to a standby state.

If "N" in step 424, step
The process proceeds to 428, where the movable plate 50 is moved to the paper feeding point (the paper feeding port 8a is opened in the horizontal state) by the motor M2.

At step 429, it is confirmed again that the battery has run out.
If it is determined that the battery has reached the end of its life, the process shifts to the standby state; otherwise, the process shifts from step 430 to step 431,
The motor M1 starts to feed the sheet paper P.

At step 430, a time limit is set to the timer q of the control unit F for 8 seconds from the start of the motor M1.
If the sheet paper P is not sent out from the outlet 8a during the 8 seconds, it is determined in step 432 that the sheet is jammed, and the process proceeds from step 433 to step 435, where the feeding of the sheet paper P is stopped. LED2 is lit for 5 seconds, and if the paper jam continues, the movable plate
Return 50 to the origin (paper outlet (8a) is closed) and shift to the standby state.

On the other hand, if "N" is determined in step 432, the flow shifts to step 436, where the leading end of the sheet paper P is detected by the sheet paper detection sensor (this sensor is activated at the time of paper feeding in step 431 ( The position detection sensor operates (lights up) while the sheet paper P is moved by a distance indicated by Xa in FIG. 21 from this point.
When it is confirmed in step 437 that the sheet paper P has moved by Xa, that is, in the case of Y, the process proceeds to step 438, and the position detection sensor is not operated for the distance indicated by Y in FIG. 25 ( Off).

When the sheet paper P is moved by the distance of the Y section in step 438, the position detection sensor is restarted (lights up), and the position detection hole b is detected in step 439. When the detection of the position detection hole b is completed, the sensor stops its operation (turns off the light) in step 440, and the paper is further moved by the distance of the Z section shown in FIG. 25 to finish feeding (step 441). , 442).

When the paper moves to the Z section, the perforation c provided on the paper is held at the cutting position.

When any of the required steps is determined to be "N" between steps 436 and 438 to 441, the process returns to step 431 to repeat the same operation.

However, during this time, the paper is not smoothly fed out, and the position detection sensor detects, for example, the position detection hole b.
If the paper feeding time exceeds 8 seconds when the sheet feeding is not detected or when the sheet paper P is not fed by the distance between YZ, the process proceeds to step 432, where the LED 2 is turned on at step 434 and the paper trouble ( (Paper jam) is displayed.
In step 442, when the sheet paper P is normally fed out for a predetermined length and the sheet paper roll R is fixed by the electromagnetic brake 64, the movable plate 50 moves to the paper holding position in step 443. The sheet paper P is cut and held as before.

If the position detection sensor detects the paper end position detection hole b1 during the feeding of the sheet paper P, it is determined as Y in step 444, and step 445 is performed.
, 446, return the movable plate 50 to the origin, and
Lights paper trouble LED2 to indicate paper trouble (paper replenishment).

If "N" is determined in step 444, the seating is checked in step 447. If the user leaves the seat, the process proceeds to steps 448 and 449 and the sheet paper P
After detecting that it has been removed and released,
Return the movable plate 50 to the origin. After this, step 450
, The position detection sensor determines the presence or absence of the sheet paper P, and if "N", the process proceeds to step 451, where the motor M1 is slightly moved to move the leading end of the sheet paper P onto the movable plate 50. It goes directly to the standby state.

Incidentally, as described at the beginning of the embodiment, the operation of the sheet paper automatic supply toilet seat after the feeding of the sheet paper P is completed is the same as before, and therefore the description is omitted.

For maintenance such as replacement of the sheet paper P, the toilet seat 11 is erected in step 417, the mode of the microcomputer of the control unit F is switched from the paper feed mode to the maintenance mode, and the operation switch is pressed. If there is a trouble or the battery has run out, LED1 and LED2 light up and the trouble content is displayed.

In this case, since the motors M1 and M2 are programmed so as not to be started, the feeding of the sheet paper P is not performed.

Although this embodiment has been described using a device using a dry battery as a power source, it is needless to say that the device may be driven by a normal 100 V AC power source.

[0066]

According to the present invention, the roll of the sheet paper extended from the roll by the roll accommodating portion in which the roll of the paper roll is rotatably supported, the feeding roller driven by the feeding motor and the driven roller. In the sheet paper automatic feeding toilet seat, which has a feeding mechanism portion that holds the leading end portion and feeds the same paper to the upper surface of the toilet seat by rotation of the feeding roller, an electromagnetic brake is applied to the sheet paper roll shaft mounting portion of the roll storage unit. When mounted, the rotation of the sheet paper roll is prevented except during the feeding operation of the sheet paper, and a one-way clutch is mounted on the shaft support of the driven roller so that the driven roller is rotatable only in the feeding direction of the sheet paper. This prevents the sheet paper P from returning or loosening due to vibration, thereby maintaining an accurate stop position. It is possible to prevent a trouble, there is an effect that allows the mounting of the railway vehicle or the like of the toilet bowl.
