Next, regarding the operation of using the sheet paper automatic feeding toilet seat (A), an operation sequence explanatory diagram shown in FIG. 9 and FIGS.
This will be described in detail with reference to the flowchart shown in the figure.

First, a normal operation sequence in which no trouble occurs will be described (normal operation routine (NR) in FIG. 10),
Sheet paper automatic supply toilet seat (A) functional units (C)
(D), control unit (F), operation unit (G) and each sensor (7
0) etc. is turned on (100) and the sheet paper position detection sensor (70) does not detect the sheet paper (P) (101N), the cam moves regardless of the position of the movable plate (50). The drive motor (41) is driven (102) in accordance with a cam moving subroutine (SR1) described later to return to the home position.

Here, the origin position is a position where the delivery port (8a) is completely blocked by the barrier plate (BP) provided at the tip of the movable plate (50), as shown in FIG. 9a. The movable plate (50) is at the origin position, and the sheet paper feeding mechanism section (C) and the sheet paper cutting mechanism section (D) have the operation of the sheet paper feeding switch (71),
A state in which a series of sheet paper feeding operations can be started is called a standby state.

That is, at the origin position, as shown in FIG. 9a, the sheet paper outlet (8a) is closed at one end thereof, and dirty water or the like enters the sheet paper outlet (8) from the sheet paper outlet (8a). To prevent you from doing so.

Further, when the position detection sensor (70) does not detect the sheet paper (P) (101N), the movable plate (50)
Is already at the home position, the home position return operation (10
2) is judged to be unnecessary and the same operation is not performed.

Further, when the sheet paper (R) is replaced, the steps (101) and (102) are performed.

That is, the opening / closing lid (17) is opened, the paper tube (R1) on which the sheet paper (P) is not wound is removed from the sheet paper holders (60) (61), and a new sheet paper roll (R) is attached to the sheet paper. Attach to the holder (60) (61).

After that, the sheet paper (P) is delivered from the sheet paper roll (R) to the feeding roller (33) and the pressing roller (34).
It is long enough to hold it between the sheet paper and the sheet paper position detection sensor (70)
Rewinding in a state that does not detect the rewinding end of the sheet paper (P), the rewinding end of the sheet paper (P) is swung forward, and the rewinding end (33) and the pressing roller (34). )
Hold it in between.

Then press the sheet paper feeding switch (71),
The operation proceeds through the steps (101) and (102).

In this state, when using the flush toilet (10), when the sheet paper feeding switch (71) is pressed (103), an operation start signal is input to the control unit (F) and read from the memory (p). Based on the sheet paper feeding / cutting sequence program, the control unit (F) generates a drive signal, and the drive signal causes the cam of the sheet paper cutting mechanism unit (D) as shown in FIGS. 9a and 9b. The moving drive motor (41) operates.

That is, when the sheet paper feeding switch (71) is pressed (10
3) First, by the seating detection means (72), the person
1) Seated or not, or toilet seat body (1
1) determines whether it is standing up or not (104), and if it is not seated or standing up (104N), according to the operation sequence in the cam moving subroutine (SR1) (Fig. 11), the cam moving drive is performed. The motor (41) is driven (10
5) By the same drive, the movable plate (50) is rotated counterclockwise by the clockwise rotation of the disc cam (44), and the sheet paper delivery port (8a) is formed on the movable plate (50). A sheet paper delivery path (8) communicating with each other is formed (Fig. 9b).

After that, as shown in FIGS. 9c, 9d, 9e, and 9f, the sheet paper feeding subroutine (SR2) (12th
According to the operation sequence shown in the figure), the sheet paper feeding drive motor (40) and the cam movement drive motor (41)
Are driven (106), the sheet paper (P) is fed from the sheet paper roll (R), and the sheet paper (P) is clamped to provide tension, and the sheet paper (P) is perforated (c). It will break.

Further, in the above step, when the toilet seat body (11) is in the rotation standing state or is seated for some reason including mischief, it is detected by the seating detection means (72) (104Y ), As long as there is the same detection output, do not send the drive output to the cam movement drive motor (41) at the origin position and the sheet paper feeding drive motor (40) of the sheet paper feeding mechanism section (C). Therefore, the sheet paper (P) is not delivered (104Y).

Then, when the toilet seat body (11) is returned to its original horizontal seating position,
The seating detection means (72) is turned off (104N), the movable plate (50) moves via the steps (105) and (106) to open the sheet paper delivery port (8a), and the sheet paper (P). ) Can be automatically fed out onto the toilet seat body (11) (106).

Then, the sheet paper (P) is delivered onto the toilet seat body (11), and then the sheet paper position detection sensor (70) detects the through hole (b) provided in the sheet paper (P) within a predetermined time. Then, the sheet paper feeding drive motor (40) is stopped in a state where the sheet paper (P) is fed onto the toilet seat body (11) by the set length (Fig. 9d).

At this time point, the perforation (c) located at the rear end of the sheet paper (P) is located substantially directly below the sheet paper cutting portion (58) of the swing plate (51).

After that, the cam moving drive motor (41) is restarted by the drive signal from the control unit (F), and the sheet paper (P)
Is clamped (held) between the sheet paper pressing pieces (56) (57), and the feeding roller (33) and the pressing roller (3
When the cam moving drive motor (41) continues to be driven after being clamped (holding) even during 4), tension in the feeding direction is applied to the portion of the sheet paper (P) located between both clamp portions. This will be the case (Fig. 9e).

Further, when the cam moving drive motor (41) continues to drive, the sheet paper cutting portion (58) of the swing plate (51).
Presses the sheet paper (P) along the perforations (c), and the pressing force and the tension in the feeding direction surely rupture the sheet paper (P), that is, cut the sheet paper (P). Figure).

The rear end of the cut sheet paper (P) is securely clamped by the sheet paper pressing pieces (56) (57) (Fig. 9f).

After that, when the user sits on the toilet seat body (11), the seating detection means (72) detects that the seat is seated (108), and the mischief prevention time (for example, 5 seconds) elapses (109). After that, when the user leaves the one-seat main body (11), the seating detection means (72) is turned off (110), and if the off signal is output abnormally continuously for 2 seconds (111Y), control is performed. The section (F) again sends a drive signal to the cam moving drive motor (41) to cause the cam moving drive motor (41) to move to the movable plate based on the cam moving subroutine (SR1) shown in FIG. It is driven until the (50) moves to the sheet paper removable position (112). By this, the clamp of the sheet paper (P) is released (Fig. 9g).

After that, the user removes the sheet paper (P) of the toilet seat body (11) (113) or drives the washing device to wash the inside of the flush toilet (10), and
It is possible to remove the sheet paper (P) by wrapping the cut-off portion of the sheet paper (P) together with the wash water and dirt and letting it flow out (113).

If the sheet paper (P) is removed (11
3Y), that is the sheet paper position detection sensor (70)
Is detected, and the detection output drives the cam movement drive motor (41) until it returns to the origin position (114) based on the subroutine (SR1) shown in FIG. 11, and the tip of the movable plate (50). By the sewage prevention barrier (BP) installed in
Completely close the sheet paper outlet (8a) (9h)
Figure).

That is, the movable plate (50) is a sheet paper outlet (8
The function box (1) should have a posture that can surely prevent entry into the sheet paper delivery path (8) through (a).
5) Can be taken within.

After that, the drive motor (40) for feeding the sheet paper is restarted, and the tip of the sheet paper (P) advances toward the toilet seat body (11) by a slight length from the sheet paper outlet (8a), for example, 20 mm. Then, the paper is fed out to prevent the paper jam (115), and the switch (7) for feeding the sheet paper by the user, which is the step of the normal operation routine (NR), is performed.
Waiting for switch operation (103) in 1) (Fig. 9h,
(Fig. 9a).

Next, a trouble processing routine (TR) relating to measures to be taken when a trouble such as an instantaneous power failure occurs during execution of the above-described normal operation routine (NR) will be described.

That is, in step (100), the mechanism units (C) (D), the control unit (F), the operation unit (G), the sensors (70) (71), etc. of the automatic sheet paper feed toilet seat (A) are After turning on the power, the sheet paper position detection sensor (7
When (0) detects the sheet paper (P), (101
Y) As a next step, the movable plate position detection sensor detects whether or not the movable plate (50) is at the origin position so that the sheet paper (P) can be removed (11
6) If it is not at the origin position (116N), the cam moving drive motor (41) is driven (117) according to the operation sequence of the cam moving subroutine (SR1), and the movable plate (50) is moved to the position shown in FIG. 9g. Bring the sheet paper to the removable position shown in (117).

After that, the building maintenance personnel and users remove the unclamped sheet paper (P) from the functional unit box (15) to remove it.

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), a step forming a part of the normal operation routine (NR) described above. Move to (114).

That is, the cam moving drive motor (41) is driven again based on the subroutine (SR1) shown in FIG. 11, the movable plate (50) returns to the origin position (114), and the tip of the movable plate (50). The sheet water outlet (8a) is completely closed by the sewage prevention barrier (BP) provided at the same time, and the sheet paper (P) is advanced about 20 mm toward the toilet seat body (11) (Fig. 9h). It waits for the operation (103) of the sheet paper feeding switch (71) by the user or the like.

In addition, in the above-mentioned trouble treatment routine (TR), as in the replacement work of the sheet paper roll (R), the opening / closing lid (1
By opening 7), turn off the power once, and then set the tip of the sheet paper (P) to the sheet paper outlet (8a).
From the toilet seat body (11) to the fully rewound state,
It is conceivable that the sheet paper roll (R) is mounted in the functional unit box (15) and then the opening / closing lid (17) is closed to re-energize.

In this case, when the sheet paper position detection sensor (70) detects (101Y) that the sheet paper (P) exists in the functional unit box (15) and the movable plate (50) is at the origin position. (116Y), the process proceeds to step (118) without driving (117) the cam moving drive motor (41).

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

Therefore, the maintenance personnel send a sheet paper feeding switch (71).
If you press (119) and the seating detection means (72) is off (120Y), the cam movement subroutine (SR
According to the operation sequence of 1), the cam moving drive motor (41) is driven, the movable plate (50) is moved to the sheet paper feeding possible position shown in FIG. 9b (121), and the sheet paper (P) is fed. Is possible.

After completion of the cam movement operation, the sheet paper feeding drive motor (40) is driven in accordance with the operation sequence of the sheet paper feeding subroutine (SR2), and the sheet paper (P) is fed toward the toilet seat body (11), After that, (P) is clamped and then cut from the perforation (C), and the clamped state is maintained as it is (12
2).

Then, in the sheet paper feeding operation (122),
Subroutine for sheet paper feeding (SR2) described later
When the flag (F1) (paper jam) in FIG. 12 is not detected (123N), the process moves to the cam movement operation step (112) which is a part of the normal operation routine (NR).

In the same step (112), the movable plate (50)
By driving the cam moving drive motor (41) based on the subroutine (SR1) shown in FIG. 11, the cam moves to the sheet paper removable position (FIG. 9g) and the movable plate (P) of the sheet paper (P) 50) and rocker plate (5
1) Release the clamp by and.

After that, when the maintenance staff pulls out the sheet paper (P) on the toilet seat body (11) and removes it, the sheet paper (P)
The sheet paper position detection sensor (70) detects that the sheet has been removed, and based on the detection output, the movable plate (50) returns to the original position again as described above (11
4), in step (103), sheet paper (P)
(115), and waits for the user to switch the sheet paper feeding switch (71).

Then, in the normal operation routine (NR), the user
By operating the sheet paper feeding switch (71), the sheet paper (P) is fed to the toilet seat body (11) in the order described above.

In the step (123), the flag (F) in the sheet paper feeding subroutine (SR2) shown in FIG.
When (1) is detected (123Y), it is determined that a paper jam has occurred and an abnormal signal generating means such as an LED is driven to notify the user (124a), and the cam movement subroutine (SR1) operation According to the sequence, the cam moving drive motor (41) is driven to move the movable plate (50) to the 9a
After returning to the origin position shown in the figure or FIG. 9h (124), all the control functions of the sheet paper automatic feed toilet seat (A) are stopped.

After that, the maintenance staff opens the opening / closing lid (17) (this opening operation turns off a power switch (not shown) incorporated in the function unit box (15) to ensure safety). It is possible to remove the sheet paper (P) jammed in the functional unit box (15) by swinging the suspension frame (35) forward.

Then, in such removing work, the movable plate (50)
Is located at the origin position, the hanging plate frame (35) can be easily swung without the movable plate (50) and the hanging frame frame (35) interfering, and the sheet paper (P) can be removed. Work can be performed easily.

Also in the normal operation routine (NR), the flag (F1) (paper jam) or the flag (F2) (paper replenishment) in the sheet paper feeding subroutine (SR2) in FIG. 12 is detected in step (107). In the case (107Y), an abnormal signal generating means such as an LED is driven to inform the user (125a), and a cam moving subroutine (SR1)
Drive motor for cam movement (41) according to the operation sequence of
Is driven, the movable plate (50) is returned to the origin position shown in FIG. 9a or 9h, and all the control functions of the sheet paper automatic feed toilet seat (A) are stopped (125).

After that, the maintenance staff opens the open / close lid (17) and (as a result of this opening operation, as described above,
The power switch (not shown) incorporated in the function box (15) is turned off to ensure safety), and the suspension frame (35) is swung forward to move the function box (15). The sheet paper (P) jammed inside can be removed, and the sheet paper roll (R) can be replaced.

Even in such sheet paper removing work, since the movable plate (50) is at the origin position, the hanging plate frame (35) can be easily moved without the movable plate (50) and the hanging frame frame (35) interfering with each other. The sheet paper (P) can be easily removed.

Further, in the normal operation routine (NR), after the sheet paper (P) is delivered (106) onto the toilet seat body (11), the delivered sheet paper (P) is unusable for some reason (for example, , The sheet paper (P) is wet, and the sheet paper (P) is kinked or wrinkled or has holes, so that the user does not sit down (108).
N), if the sheet paper feeding switch (71) is operated again (126Y), the process moves to the cam moving step (112), and the sheet paper (P) that is in an unusable state or is undesired is used. Can be easily removed (11
3).

Further, after the sheet paper (P) is drawn out onto the toilet seat body (11) (106), the user does not sit on the toilet seat body (11) for some reason (for example, mischief) (108N). In addition, when a certain time (for example, 1 minute) has passed without operating the sheet paper feeding switch (71) (126N) (127Y), the process immediately proceeds to the cam moving step (112), The user of the toilet seat body (1
1) It is possible to remove the sheet paper (P) that has been fed out (113) Next, regarding the contents of the above-described cam moving subroutine (SR1) and sheet paper feeding subroutine (SR2), FIG. Also, description will be made with reference to FIG.

First, the cam movement subroutine (SR1) will be described with reference to FIG. 11. If the disc cam (44) has already reached the designated cam position (201Y), the normal operation routine shown in FIG. Return to (NR) or trouble shooting routine (TR).

On the other hand, when the disc cam (44) has not reached the designated cam position (201N), the cam moving drive motor (41) until it reaches (203) is driven to reach the designated cam position. In case (204Y), the cam moving drive motor (41) is stopped (205), and then the normal operation routine (N
R) or return to the troubleshooting routine (TR).

In addition, when the movable plate position detection sensor malfunctions or is driven by the cam movement drive motor (41) (203),
If the disc cam (44) does not reach the specified cam position after the set time (for example, 5 seconds) elapses (203Y), (20
6) When it is judged that a trouble has occurred, the drive motor for cam movement (41) is stopped regardless of the positions of the disc cam (44) and the movable plate (50), and all the seat paper automatic feed toilet seats (A) are stopped. The control function is stopped (207).

As a result, the cam moving drive motor (41) can be prevented from being burnt out due to overheating, and the contact surfaces of the movable plate (50) and the swing plate (51) can be repeatedly slid. Wear can be prevented.

Next, the sheet paper feeding sub-routine (SR2) will be described with reference to FIG. 12 by the drive of the sheet paper feeding drive motor (40) (301) before a set time (for example, 8 seconds) elapses (302N). ), If the sheet paper position detection sensor (70) detects the through hole (b) (30
3Y), its detection sheet paper feeding drive motor (40)
It is judged that the paper has not ended because the set time (for example, 2 seconds) has elapsed after the start of driving (304Y), the sheet paper feeding drive motor (40) stops, and the feeding roller (33)
And sheet paper (P) by pressing roller (34)
Clamp (305).

Next, the cam moving drive motor (41) is driven (306),
When the movable plate (50) comes to a position where the sheet paper (P) is clamped by cooperation with the swing plate (51) (307), the drive of the cam movement drive motor (41) is stopped to clamp. (308) and then returns to the normal operation routine (NR) or trouble handling routine (TR) shown in FIG.

Also, the above-mentioned sheet paper feeding subroutine (SR2)
In (3), after driving the drive motor (40) for feeding the sheet paper, the through hole (b) of the sheet paper (P)
If about 8 seconds have passed without detecting (302Y),
When it is judged that a paper jam has occurred (309), the flag (F1) is turned on, and the drive of the sheet paper feeding motor (40) is stopped (305).

On the other hand, even when the sheet paper position detection sensor (70) detects the through hole (b) (303Y), if it is within 2 seconds from the start of driving the detection sheet paper feeding drive motor (40). (304N), the sheet motor (-(P) of the sheet paper roll (R) is used up, it is judged that the paper needs to be replenished (310), the flag (F2) is turned on, and the sheet paper feeding drive motor The drive of (40) is stopped (305).

When the paper jam and the paper replenishment state occur, the process returns to the normal routine (NR) through the operation steps (306) (307) (308), and the lag (F1) or flag (F2) is set in the operation step (107). Since it will be detected (107), the abnormal signal generating means such as an LED is activated to notify the user of the occurrence of the abnormal state (125a), and the cam is moved based on the subroutine (SR1) shown in FIG. The drive motor (41) is driven to return to the original position (125), and the sheet paper automatic feed toilet seat (A) stops all control functions.

In addition, the movable plate position detection sensor failed, and after the cam moving drive motor (41) was driven (306), the disc cam (4)
If 4) does not reach the specified cam position within the set time (for example, 5 seconds) (307N), (311Y), it is judged that a trouble has occurred, and the drive motor for cam movement (41) is driven. , The disc cam (44) and the movable plate (50) are stopped regardless of their positions, and all the control functions of the seat paper automatic feed toilet seat (A) are stopped (312).

This allows the sheet paper feeding subroutine (SR
Also in 2), like the cam moving subroutine (SR1), it is possible to prevent the cam moving drive motor (41) from burning out due to overheating, and the movable plate (50) and the swing plate (51). It is possible to prevent abrasion due to repeated sliding of the contact surfaces with each other.
