[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device that automatically supplies sheet paper to cover the seat of a Western-style toilet bowl, and its purpose is to provide a protective cover for a sheet paper roll. To provide an automatic sheet paper supplying toilet seat equipped with a safety device that prevents the motor from being energized even when the protective cover is correctly set in the casing when removed from the casing or in the event of equipment failure. be. [Prior Art] In recent years, for Western-style toilets, devices for automatically placing sheet paper on the toilet seat in consideration of hygiene during use have been developed, for example, the device for toilet seats described in Japanese Utility Model Application Publication No. 155399/1983. A Kahar feeding device can be seen. Then, the device winds up a continuous sheet paper shaped into a size and shape that can completely cover the top surface of the toilet seat into a roll shape, stores it in a protective cover, and stores the rolled sheet paper in a protective cover. A barber holder that supports a sheet paper roll wound up on a rack so that it can be continuously fed out, a feed roller device that feeds out a fixed amount of sheet paper fed out from the sheet paper roll onto a toilet seat, and a It consists of a cutting device equipped with a cutting blade to separate the rear end side of the sheet paper that has been fed out in a fixed amount from the sheet paper roll, and the feeding operation is performed by turning on the paper feeding switch and moving the sheet paper to the feeding roller. After dispensing a fixed amount onto the toilet seat using a device, the sheet paper was cut by moving the cutting blade up and down. In this way, when using a Western-style toilet, you can automatically spread sheet paper on the toilet seat and sit down.
Very hygienic. [Problems to be Solved by the Invention] However, in the toilet seat cover supply device that automatically supplies sheet paper onto the toilet seat, no measures are taken to ensure safety. For example, when replacing the sheet paper, or when replenishing the sheet paper roll or clearing the paper jam, such as when the sheet paper becomes entangled inside the feeding device and a paper jam occurs, remove the protective cover and replenish the paper. etc. In this case, since the feeding device is generally energized, if the paper feed switch is accidentally touched and turned on during the above operation, the feed roller device and cutting blade will operate, which is extremely dangerous.
To prevent this, the power had to be turned off and on each time the work was done, which was very frequent. In addition, if the supply device requires repair due to some kind of malfunction,
If the power cord is disconnected from the power source until repair, and the user plugs the power cord into the power source and turns on the paper feeding switch without knowing that there is a malfunction, the feeding device may become energized and operate abnormally. There was a risk that repairs would become impossible or that incorrect energization could cause an electric shock accident. In this way, when installing a toilet seat cover supply device on a Western-style toilet that is used by a small number of people in a general household or an unspecified number of people in public facilities, etc., light work such as replenishing paper and removing paper jams is necessary. , it was necessary to ensure that the power supply was shut off so that even a person who was not familiar with the structure of the device could easily perform the operation, and as mentioned above, there was no danger to the user. ．． In view of the above problems, the present invention automatically cuts off the power to the sheet paper supply device by opening the protective cover of the sheet paper supply device when replenishing sheet paper or removing paper jams.
Further, the purpose of the present invention is to provide an automatic sheet paper feeding toilet seat equipped with a safety device that prevents the feeding device from being energized even if the feeding device is covered with the protective cover until repairs are made in the event of a breakdown. shall be.

The protective cover 16 can be fixed to the casing 4 by engaging with the engaging recess 69 of the protective cover 16. Next, the operation will be explained.

When the sheet paper C is not delivered to the toilet seat 3, the paper delivery port 17 is closed by the end of the movable plate 20, as shown in FIG. 4, to prevent sewage from entering the casing 4. When I go to relieve myself, I press the paper
When dispensing paper onto the toilet seat 3, press the paper dispensing switch 33.
Press to start the electric motor 25, which causes the disc cam 24
As shown in FIG. 3, the movable plate 20 is rotated to a position parallel to the paper feed path 21 via the driven roller 23 to open the paper outlet 17. At this point, the electric motor 25 is not shown. It is temporarily stopped by a command from the control device, and the other motor 18 is stopped by a command from the control device instead.
Start. As a result, the feed-out port 15 rotates, and while unwinding the sheet paper C supported between the roller 15 and the pressing port-ra 19 from the sheet paper roll 10, the movable plate 20 → the feed port 17 is rotated. Then, it is sent onto the toilet seat 3. As described above, when the sheet paper C is fed out to a length that covers the toilet seat 3, the paper feeding position detection sensor 2
8 detects the through hole 29 of the sheet paper C, and in response to this detection signal, a stop signal is sent from the control device to the electric motor 18 to stop it. As a result, the sheet paper C is dispensed in a fixed amount onto the toilet seat 3, and the perforation 30 is located at the dispensing opening.
It is located between the rear l5 and the fracture protrusion 14. electric motor
8 stops, the control device 1 sends a starting start signal to the electric motor 25 again, and the movable plate 20 is moved again to the disk cam 2.
4, the counterclockwise side in FIG. 5, that is, the rotating plate 12.
5, the movable plate 20 comes into contact with the rotating plate 12 and lifts the sheet paper C lying on the paper delivery path 2l toward the rotating plate 12, as shown in FIG. When rotated clockwise, sheet paper C is supported between both plays}12.20 and
The breaking protrusion l4 lightly contacts the sheet paper C.

In this state, the movable plate 20 continues to rotate further by the disc cam 24, and when the disc cam 24 rotates about half a turn from the start, the movable plate 20 changes from the tilted state shown in FIG. 5 to the state shown in FIG. 6. , tilt to the maximum angle. During this time,
The rotating plate 12 is also pushed by the movable plate 20 and further rotates clockwise, and as shown in FIG.
Rotate the contact point with sheet paper C at 1-1.
Press in the rotation direction of 2. As described above, due to the rotation of the movable plate 20, a large tension is applied to the sheet paper C between the movable plate 20 and the feed-out port l5, and at the same time, the sheet paper C is pushed by the movable plate 20 and rotated. Since the breaking protrusion 14 of the movable plate 12 strongly presses the contact point with the sheet paper C, the perforation 30 near the breaking protrusion 14 of the sheet paper C is torn at the same time as shown in FIG. 3. Break the sheet paper C equivalent to one sheet to be laid on top.

When the sheet paper C is broken, the electric motor 25 is stopped by a command from the control device, and the sheet paper C is rotated as shown in FIG. It can be held between the movable plates 12 and 20 and placed on the toilet seat 3 without shifting as shown in FIG. In this state, the user sits on the toilet seat 3 via the sheet paper C, and inserts the punched piece 3l into the toilet bowl 2.
It is used to relieve errands by hanging inside. When the user leaves the toilet seat 3 after relieving himself/herself, the control device sends a start command to the electric motor 25 by the seat detection means (not shown), rotates the disc cam 24 clockwise, and moves the movable plate 20 to the sixth position. Rotate clockwise (direction to return to original position) from the state shown in the figure. At this time, since the pressure on the rotating plate 12 by the movable plate 20 is gradually released, the rotation plate 12 is
Return to the original position with the force of. Note that when the user leaves the toilet seat 3, the sheet paper C is in a supporting state, so that it does not wrap around the user's buttocks. Thereafter, flushing water is poured into the Western-style toilet bowl 2, and the force of the water drags the punched piece 3L of the sheet paper C into the interior of the toilet 2K2, and the sheet paper C is discharged together with the dirty water. When the movable plate 20 returns to its original position, it closes the paper outlet 17 to prevent infiltration of dirty water. When the next user needs sheet paper C, they can perform the same operation as above. next,
A case where the protective cover 16 is removed from the casing 4 when replenishing the sheet paper roll 10, clogging the sheet paper C, etc. will be described.

First, when removing the protective cover 16, as shown in FIG.
and the cover 16 are pressed into the gap k between the corresponding side ends, and the retaining claw 67 is pulled away from the engagement recess 69 to release the hook member 66, and the protective cover 16 is pressed in the same state.
Lift it directly above the casing song 4 and open it from the casing 4. As mentioned above, when the protective cover 16 is opened,
Pressing bottle 62 of input regulating member 55 provided inside cover 16
However, Fig. 17. As shown in FIG. 19, since the switch mounting body 44 is removed from the through hole 65 of the casing 4 and the pressure on the switch mounting body 44 is released, the compression spring 4
When the push button 43a of the switch 43 contacts the stopper 50 protruding from the edge of the insertion hole 46 of the mounting box 42, the switch mounting body 4
4 is prevented from moving upward and shuts off the switch 43, thereby opening the energizing circuit (not shown) of the drive machine 11m36. That is, when the protective cover 16 is removed from the casing 4, the closing regulating member 55 and the switch member 4l, which constitute the safety device 140, are separated as described above, so that the switch 43 is automatically shut off. Therefore, it is necessary to replace the sheet paper roll 10 or replace the casing 4.
Even if the paper feed switch 33 is turned on by mistake while removing paper jams inside the printer, the drive mechanism 36 will not operate. After completing the above work, as shown in Figure 7,
When the protective cover 16 is placed over the casing 4, the hook member 66 is pressed against the side wall of the protective cover l6, and presses the retaining piece 68 into the gap k as shown by the two-dot chain line in FIG. When the locking claw 67 is misaligned with the position of the engagement recess 69,
The engaging piece 68 automatically returns to the protective cover 16 side due to the elastic force when pressed, and the engaging claw 67 is engaged with the engaging recess 69 to properly hold the protective cover 16 on the casing 4. As the protective cover 16 is hung properly, the pressing pin 62 of the input regulating member 55 is pushed into the through hole 6 of the casing 4, as shown in FIG.
5 into the insertion hole 46 of the switch-chip mounting box 42, push the switch-chip mounting body 44 downward, release the pressure on the pusher opening 43a, and insert the switch-chip 43. As a result, the energizing circuit of the drive mechanism 36 is closed, and by turning on the paper feed switch 33, the sheet paper C can be fed out.

Next, a case will be explained in which when the automatic sheet paper supply toilet seat l breaks down and requires repair, the drive machine side 36 is not energized until the repair person starts the repair.
In this case, the protective cover 16 is removed from the casing 4 by releasing the hook member 66, and the pressing pin 62 of the input regulating member 55 attached to the top inside the protective cover 16 is inserted into the 13th position.
Move from the position shown in the figure, that is, the right side (ON) of the figure, to the left side (OFF) as shown in FIG. At this time, the engagement protrusion 6l on the elastic seat plate 60, which is formed by drilling two notched grooves in the regulation plate 56, engages with the retaining groove 64 of the circular seat 58. The force when moving the regulating plate 56 to the right or left with the pin 62 causes the elastic seat plate 60 to move to the first position.
Press downwards as shown by the two-dot chain line in Figure 2 to remove the engagement groove 64.
16, push the press bottle 62 to the left (O
When moved to FF), the engagement protrusion 6l slides into contact with the circular seat 58 and rotates while pressing the elastic seat plate 60 downward, and the other engagement groove 64 provided on the opposite side of the pressing pin 62 is positioned. When reaching this point, the engagement protrusion 6l engages with the engagement groove 64 due to the elastic force of the elastic seat plate 60 itself, and prevents movement of the regulation plate 56 (see FIG. 16). The regulation plate 56 of the input regulation member 55 is rotated as described above, and the position of the pressing pin 62 is approximately 18
When the protective cover 16 is placed over the casing 4 while being moved by 0°, the pressing pin 62 of the input regulating member 55 does not enter the through hole 65 of the casing 4, but closes to the left side of the casing 4, as shown in FIG. Since it is moving in the opposite direction, the switch member 4l cannot be inserted. That is, since the pressure on the switch member 4l by the press bottle 62 has already been released due to the opening and covering of the protective cover 16, at this point, the switch attachment body 44 moves upward and blocks the switch 43 as described above. ing. In this state, even if the input regulating member 55 is operated to cover the protective cover 16 as described above, the switch member 4l will not operate at all.
When the switch 43 is closed by the protective cover 16, the energizing circuit on the side of the drive machine 36 is not closed.
As a result, in the event of a device failure, the drive mechanism 36 will not be energized even if the power cord is plugged into the power source, and as a result, even if the paper feeding switch 33 is operated, the drive mechanism 36 will not operate and will not be energized. This can prevent problems such as expansion of the failure location and electric shock accidents. [Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

(1) When replenishing sheet paper rolls or removing paper jams, when the protective cover is removed from the casing, the swing input member of the drive mechanism and the input restriction member provided on the protective cover are configured to be separable. Even if the paper feed switch is turned on by mistake, the drive mechanism will not operate at all, allowing maintenance such as replenishment and removal of paper jams to be performed safely. (2) In addition, when the closing control member does not close the switch member as necessary, it is only necessary to set the press pin for the closing operation to the position where the switch member is not closed, and this allows the protective cover to be closed. Even if it is covered with a casing, the drive mechanism cannot be energized, and in the event of a failure, there is no possibility of enlarging the failure area or causing an electric shock accident due to energization. Furthermore, when the equipment is out of order, the caning can be covered with a protective cover, preventing sewage and dust from entering the casing. Furthermore, the switch that opens and closes the energizing circuit of the drive mechanism cannot be turned on unless the pressure bottle of the regulating member is inserted into the insertion hole of the switch member, so maintenance must be performed with the protective cover open. can be done safely and in real life.
