It is configured to include a first motor circuit (for paper feeding) 105 and a second motor circuit 106 by individually connecting X3a and X3b and paper feed motors M1 and M2 in series.

In the sheet paper automatic feeding toilet seat A constructed as described above, the gist of the present invention is that the operating amount detection means of the feeding mechanism section C is an optical system using an incremental type rotary encoder 113a. The objective is to detect the

That is, in order to detect the rotation speed of the feeding motor M1, a rotation speed detection circuit 113 shown in FIG. 13 is connected to the input terminal of the microcomputer 104. An incremental type rotary encoder 113a is used, and as shown in FIGS. 5 and 6, the rotary encoder 113a is attached to the rear of the feeding motor M1 so as to rotate coaxially therewith.

Now, to explain the incremental type rotary encoder 113a, its structure is as shown in FIG. 20. As the shaft 113a-1 rotates, a disk 113a-2 on which black and white patterns are written rotates. Accordingly, two slits 113a are provided for A phase and B phase.
-3, 113a-4 is transmitted or blocked, and this light is converted into a current by a phototransistor 113a-6 installed opposite each slit, and is output as two rectangular wave trains by waveform shaping. The number of output pulses is counted by the microcomputer 104, and the amount of rotation can be detected from the number of counts.

Incremental pulse signals cannot be identified individually, so in order to know the amount of rotation from a certain input shaft position, the number of pulses from that position must be cumulatively added by a counter. It can be selected arbitrarily, and the amount of rotation can be measured infinitely.

Note that the two-phase signal slit 113a-5 is
A signal is generated only once per rotation of the disk 113a-2 and is used as the coordinate origin.

In the figure, 113a-7 indicates a light emitting diode.

In this way, the rotary encoder 113a
By using this, it consumes less power than conventional Hall elements, and in the case of battery-powered automatic sheet paper supply toilet seats, accurate rotation speed can be detected even when the battery voltage drops. This eliminates the drawback of conventional Hall elements, which is the inaccuracy of operation that occurs near the usage limit of the battery voltage.

Next, the operation of the automatic sheet paper supplying toilet seat will be explained with reference to FIGS. 18 and 19.

First, when the feeding switch 71 is turned on (2
01), energize the rotary encoder 113a and the movable plate position detection sensors 93, 93a (202)
. At this time, if the toilet seat body is standing or sitting (203Y), the microcomputer 104 is switched to maintenance mode (204).

[0044] The toilet seat body etc. is not upright, and
When not seated (203N), the movable plate 50
is moved from the original operating position (FIG. 19(a)) to the cam/paper feeding position (where the movable plate 50 is held horizontally and the paper feeding port 8a is opened) (FIG. 19(b)) (205).

After the movable plate 50 is moved, the timer in the microcomputer 104 is set (8 seconds) (206), and the timer is started (207).
, starts the feeding motor M1 and starts feeding the sheet paper (FIGS. 19(c) to 19(d)) (208)
.

Then, steps 2080, 20 in FIG.
81, in step 2081, the leading edge of the paper is detected by the paper position detection sensor 70 (the sensor 70 lights up at the start of the feeding motor M1),
Moreover, when it is confirmed in step 2082 that the paper has moved by the length Xa (see FIG. 17), step 2
The process moves to step 084, and in step 2084, the paper is fed out by the distance of the Y section. Note that during feeding in the Y section, the paper position detection sensor 70 is turned off. Then, when the paper is moved by the Y interval in step 2084, the sensor 70 is turned on again, and the paper position detection hole b is detected in step 2086, and after the detection, the light is turned off again. Note that the paper further moves by Z section and ends feeding. That is, after the detection hole b is detected, when the paper is slightly moved by the Z section in step 2085, the feeding motor M1 is stopped. Therefore, the perforation c provided in the paper can be reliably set at the cutting position.

[0047] Note that if it is determined "N" between steps 2081 to 2085, step 2080 is performed in all cases.
Return to , repeat the same operation, and sheet paper P
When the feeding motor M1 stops to finish feeding the (
209), the motor M2 for cutting etc. starts and moves the movable plate 50 to the paper holding position (210) (Fig. 19(e)
~(f)), the paper is cut and clamped at the same time.

On the other hand, when the sheet paper is being held, the seating detection sensor 72 is energized (203, 211
etc.), when the user leaves the toilet seat (211), the seating detection sensor 72 is turned off, and the movable plate 50 is immediately moved from the paper holding position to the holding release position by the cutting motor M2 (FIG. 18(g)). (212) The sheet paper P can be flushed with washing water or removed from the toilet seat by hand.

When the paper position detection sensor 70 detects the removal of the sheet paper P, the movable plate 50 immediately returns to its original position and can continue feeding out the next paper (213). ,214,21
5,218,219). Furthermore, if the paper position detection sensor 70 does not detect the removal of the sheet paper P, the movable plate 50 returns to its original position after one minute and can continue to feed out the next paper. (213, 214, 215, 216, 217
, 218, 219) (Figure 19(h)) (213-21
7).

Note that the paper position detection sensor 70 is
The light goes out until the next feed switch is operated.

However, the 8 set in step 206
When the seconds have passed (2080Y), if the sheet paper is not fed out normally due to paper jam, voltage drop, failure of the feeding motor M1, etc., the presence or absence of sheet paper is determined by the paper position detection sensor. 70 (2086), and if there is sheet paper (20
86Y), proceed to the following steps.

In other words, Y indicating the sheet paper feeding length
The rotational speed of the feeding motor M1 in the section is substantially 70.
% or more (2087Y) (this is detected by the rotary encoder 113a), the drive time of the feeding motor M1 is extended by "4 seconds" (2088) and the sheet paper P is fed out again. , it is possible to control the feeding of the remainder of the sheet paper P to perform normal paper feeding, and to reduce the number of times the feeding motor M1 has to be stopped.

[0053] Also, in step 2086, "N" or Y
The rotational speed of the feeding motor M1 in the section is substantially 70.
% (2087N), it is assumed that a serious malfunction such as a paper jam, voltage drop, or motor failure has occurred, and the feeding motor M1 is stopped (2089), and this operation is continued until the above malfunction is resolved and reset. Maintain the stopped state.

[0054] The above describes the operation after the sheet paper P is fed out, the user sits down and leaves the seat, the paper P is removed, and the machine enters a standby state for feeding the next sheet paper. In particular, during such operation, the number of rotations of the paper feeding motor is detected within a predetermined time using a timer such as a timer and a rotation speed detection means such as a rotary encoder, and the detected number of rotations is equal to or less than a predetermined number of rotations. In this case, it is assumed that a paper jam or a failure of the paper feed motor has occurred, and the paper feed motor is stopped to prevent overloading of the motor and further worsening of the paper jam condition. be able to.

Furthermore, when the number of rotations of the feeding motor M1 is less than a predetermined number of rotations, the operation of the feeding motor M1 is not stopped entirely, but the feeding motor M1 is stopped in the Y section.
1 is rotating at more than 70% of the required number of revolutions, by extending the time for 4 seconds and operating the feeding motor M1, the number of revolutions of the motor M1 can be reduced due to a slight voltage drop or a slight paper jam. Since the paper can be normally fed out even when the rotation speed is less than the predetermined number, the number of times the feeding motor M1 is stopped can be reduced.

Furthermore, by using a rotary encoder as the actuation amount detection means of the feeding mechanism, the structure is simplified and power consumption is reduced. In this case, since the rotary encoder has a wide tolerance range of drive voltage, it is possible to accurately detect the rotation speed even if the battery voltage drops, and the above-mentioned problems can be detected reliably. can.

[0057] After driving the feeding motor M1 for a predetermined period of time, the feeding motor M1 is controlled by the above-mentioned stop or extension based on the detected value of the rotation speed detection means 113a of the feeding motor M1. In addition, the predetermined driving time of the feeding motor M1 is set to be short (for example, about 2 seconds) compared to the time required to feed the paper, and at that time, the detected value of the rotation speed detecting means 113a is determined to be a predetermined value. If the value is exceeded, paper continues to be fed out, but
If the value is less than a predetermined value, the drive control of the feeding motor M1 may be reset to start feeding the paper again.

As described above, the predetermined values and predetermined times of the operating amount detecting means and the timing means of the feeding mechanism section can be changed in various ways, and the corresponding control of the feeding motor M1 can also be changed in various ways. It is possible.

[0059]

[Effects of the Invention] According to the present invention, if sheet paper is not fed out normally due to a paper jam, voltage drop, or malfunction of the feeding motor, the paper can be fed out for a predetermined period of time after the feeding motor is started. Even after the elapse of (the time required for normal feeding), the rotational speed of the motor does not reach the predetermined value (the rotational speed required for normal feeding).

Therefore, the timing means is started at the same time as the feeding motor is started, and when the timing means detects that the above-mentioned predetermined time has elapsed, the rotational speed of the feeding motor detected by the rotation speed detection means is set to the above-mentioned speed. If it is less than a predetermined value, it can be determined that the sheet paper is not being fed normally.

[0061] When the sheet paper is not being fed normally, stopping the feeding motor may overload the feeding motor and further worsen the paper jam or malfunction. problems can be prevented.

Furthermore, by using a rotary encoder as the rotational speed detection means of the paper feeding motor, the rotational speed can be detected accurately, so paper jams can be accurately detected when sheet paper is fed out, and the structure is simple. .

Furthermore, since the rotary encoder consumes less power, it is possible to extend the life of the battery, especially when used in a battery-powered automatic sheet paper supply toilet seat, and the accurate rotation speed can be maintained even if the battery voltage drops. Since this can be detected, it is possible to accurately detect a paper jam when feeding sheet paper even when the battery voltage is low.

[0064] As a means for detecting the rotational speed of the feeding motor, it is also conceivable to use a Hall element to detect changes in the magnetic field caused by the rotation of the motor, and to count the changes to detect the rotational speed. However, the Hall element consumes a large amount of power, so when used in a battery-powered automatic sheet paper supply toilet seat, the battery voltage drops so much that it becomes impossible to accurately detect the rotation speed. It is better to use a rotary encoder as a means for detecting the operating amount of the mechanism to more accurately feed out the sheet paper.
