Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a toilet seat that automatically supplies a large washable and disposable sheet paper onto the seat of a Western-style toilet bowl. To quickly and easily replace paper rolls and correct paper jams.

[Future technology]

In recent years, many Western-style toilets have come into use in hotels, restaurants, and general households. Since this Western-style toilet is used by sitting on a toilet seat that is attached to the toilet bowl so that it can be raised and lowered, it is desirable that the toilet seat is always hygienic. For this reason, in ordinary households, cloth covers are regularly replaced and installed on toilet seats, which tend to become unsanitary due to droplets of sewage adhering to them. Rather than maintaining the toilet seat in good sanitary condition, it is often used to relieve the feeling of cold when sitting on the toilet seat. Therefore, attaching a cloth cover to the toilet seat is, on the contrary,
It was easy to overlook the adhesion of sewage, and there was a risk that it would worsen the unsanitary situation. Furthermore, unlike in ordinary homes, Western-style toilets installed in public places such as hotels, restaurants, and various types of transportation used by an unspecified number of people do not usually have a toilet seat cover at all. This is the same as when a cloth cover is installed in that the toilet seat is subject to droplets of sewage directly attached to it, and furthermore, such a toilet seat is used by an unspecified number of people.
This is a major public health problem, and the desire to use Western-style toilets installed in public places in a sanitary manner is increasing day by day.

For this reason, recently, for example,
As shown in the publication, a sheet paper in the form of a roll is cut into a certain length and placed on a toilet seat.The schematic structure thereof will be explained with reference to FIG. 11. 1 is the toilet bowl, 2 is the toilet bowl 1
A paper holder 3 is rotatably housed in a sheet paper roll 4 in which sheet paper 4a is wound in a roll shape to cover the top surface of the toilet seat. Reference numeral 5 denotes a feeding cutting section that feeds the sheet paper 4a fed out from the holder 3 onto the toilet seat 2 and cuts it into a predetermined length.
A guide roller 6, a pair of delivery rollers 7a and 7b that sandwich and send out the sheet paper 4a, and cutting blades 8a and 8b that cut the sheet paper 4a are attached, and the delivery roller 7a and the cutting blade 8a are individually connected. It is configured by being connected for driving with an electric motor (not shown),
When in use, a paper feed switch (not shown) is operated to feed the sheet paper 4a onto the toilet seat 2, and the toilet seat 2 can be seated on top of the sheet paper 4a to relieve the user of errands.
Western-style toilets can be used hygienically.

[The problem that the idea attempts to solve]

In the sheet paper automatic supply toilet seat having the above structure, for example, when replacing the sheet paper roll 4, a new sheet paper roll is set in the paper holder 3, and then the sheet paper 4a is replaced.
Pull out the sheet paper 4a to the position of the guide roller 6, and in this state, remove the upper delivery roller 7b of the delivery rollers 7a and 7b from the mounting base 5a, or lift it slightly upward, and support the sheet paper 4a on the guide roller 6. The lower delivery roller 7a
Pull it out to the top. After this, the upper delivery roller 7b
The replacement work was carried out by setting the sheet paper 4a in its original position and sandwiching the sheet paper 4a between the delivery rollers 7a and 7b. Also, the mounting base 5a
When a paper jam occurs in the sheet paper 4a, as described above, remove the feed roller 7b, etc., pull out a new sheet paper 4a from the sheet paper roll 4, and then repeat the same procedure as above to reload the sheet paper 4a. I was doing some setup work.

However, the sheet paper 4a is large in size in order to cover the top of the toilet seat 2, and is made of soft thin leaves so that it can be disposed of by washing with water, so it is very weak. When replacing the roll 4, the sheet paper 4a is pulled out from the sheet paper roll 4 and transferred to the delivery roll 7.
The feeding roller 7b is sandwiched between a and 7b.
It was very time consuming and troublesome, including the handling of the process. In particular, if the sheet paper 4a is not securely held between the feed rollers 7a and 7b to prevent it from becoming loose or tangled, paper jams may occur during feeding.
There was a problem that it was not possible to unroll it smoothly, and it was difficult for women and girls to easily replace it.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide an automatic sheet paper supply toilet seat that allows easy replacement of sheet paper rolls.

Next, the electric motor 22a is started in response to a command from the control device S, and the sheet paper 17a is unwound from the sheet paper roll 17 by the feeding and pressing rollers 22 and 23, and is passed onto the movable plate 26 → through the paper outlet 20 and then to the toilet seat. Roll it out on 12. Then, when the sheet paper 17a is fed out a certain length onto the toilet seat 12, the sensor 36 detects the through hole 27 provided in the sheet paper 17a, and the electric motor 2
2a is stopped by a command from the control device S.
Therefore, the sheet paper 17a is dispensed onto the toilet seat 12 in a fixed amount, and the perforation 39 is set between the breaking protrusion 21 and the dispensing roller 22. after this. The electric motor 29a is activated by a command from the control device S, rotates the cam member 25 clockwise in FIG.
As shown in FIG. 6, the movable plate 26 interlocked with this is lifted up via the guide roller 32 with the end on the cushioning material h side closed by the rotation of the cam member 25. At the same time, a part of the sheet paper 17a in the paper delivery path 31 is lifted up and held between it and the cushioning material e of the rotating plate 19. Even after holding the sheet paper 17a, the cam member 25 continues to rotate to rotate the movable plate 26, and the movable plate 26 pushes the rotary plate 19 clockwise in FIG. 6 about the axis d. rupture protrusion 21
The sheet paper 17a is partially pressed. As a result, a large tension is applied to the sheet paper 17a between the movable plate 26 and the feeding roller 22, and at the same time, the sheet paper 17a is partially strongly pressed by the breaking protrusion 21. Therefore, the sheet paper 17a has a large tension applied thereto, and the perforation 3 near the breaking protrusion 21
9 cannot withstand the pressing force of the breaking protrusion 21 and is torn sequentially from that part, and as shown in FIG. 7, one sheet of sheet paper 17a can be broken smoothly. After the sheet paper 17a is broken, the electric motor 29a is temporarily stopped by a command from the control device S.

It is sandwiched between 6 and 19. In this state, the user hangs the punched piece 40 into the toilet bowl 11 as shown in FIG.
Sit on the toilet seat 12 via the sheet paper 17a,
Perform errands. At this time, since the end of the sheet paper 17a on the broken side is held within the box body 14, it will not move even if the body moves slightly.

When the user leaves the toilet seat 12 after relieving himself or herself, the control device S issues a command to drive the electric motor 29a using a seating detection means (not shown), and the cam member 25
Turn clockwise again. At this time, cam member 2
5 rotates from the highest position to the lowest position, the movable plate 26 also retreats toward its original position, and the pressure exerted by the movable plate 26 on the rotary plate 19 is gradually released. , the direction of the stopper d due to the force of the spring f,
That is, it returns to the original position. As a result, the sheet paper 17a is released from the pinched state. Note that when the user leaves the toilet seat 12, the sheet paper 17
Since part a is still held between the movable plate 26 and the rotating plate 19, it does not wrap around the buttocks. After that, the cleaning device is operated to clean the inside of the toilet bowl 11, and the sheet paper 17a is cleaned by the force of the cleaning water.
The punched piece 40 is dragged into the toilet bowl 11 and the sheet paper 17a is discharged together with the dirty water. on the other hand,
The cam member 25 continues to rotate, as shown in FIG.
When the motor 29a returns to the starting point, the electric motor 29a stops and rotates in response to a command from the control device S. As a result, the movable plate 26 also returns to its original position, closing the paper outlet 20.

After this, the next user will proceed to Western-style toilet 11.
When using , you can perform the same operations as above.

Next, a case where the sheet paper roll 17 is replaced will be described.

First, the cover 33 is removed from the box 14, the roller core R is pushed toward the support rod 18a against the force of the spring c, and is removed from between the support rods 18, 18a. Note that when the cover 33 is removed, a safety switch (not shown) cuts off the power supply to the control device S, etc., so that the sheet paper roll 17 can be replaced safely. Next, when installing a new sheet paper roll 17, in the same way as when the roll core R was removed, one side of the roll core R of the sheet paper roll 17 is attached to the support rod 18a.
4, press the support rod 18a into the boss part a against the spring c, press the sheet paper roll 17 toward the support plate 15a in FIG. Support rod 1 on the opposite side
8, the sheet paper roll 17
As shown in FIG.
It can be rotatably attached between the support plates 18 and 18a. In this state, the support plates 15, 15 which are pivotally connected to the side walls 16, 16 via the boss portions a, b.
a to the front of the box 14, that is, to the toilet seat 12 side, as shown in FIG.
The pressing roller 23 suspended horizontally is separated from the feeding roller 22 and moved to above the movable plate 26. After that, a part of the sheet paper 17a is rewound from the sheet paper roll 17 in the opposite direction to the winding direction, and the rewound end is rewound as shown in FIG.
After winding the sheet paper 17a around the pressing roller 23 so as to uncurl the sheet paper 17a in the winding direction and letting it hang on the movable plate 26, the support plates 15, 15 are
When the paper a is returned to its original position inside the box 14, the pressure roller 23 returns to its original position where it is in sliding contact with the roller 22, and the sheet paper 17a is moved between the pressure roller 23 and the feeding roller 22 as shown in FIG. It can be automatically sandwiched between the two.

When the sheet paper 17a is fed out, when the cover 33 is placed over the box body 14, the cover 33 itself is engaged with the fitting groove 35 of the side walls 16, 16, so when the sheet paper 17a is fed out, the support plate 15, 15a is fixed to the cover 33 without swinging.
This allows the sheet paper 17a to be smoothly fed out.

Furthermore, even if a paper jam occurs while feeding the sheet paper 17a, the paper jam can be easily corrected by pulling out the support plates 15, 15a in front of the box body 14 in the same way as when replacing the sheet paper roll 17. .

As shown in FIG. 4, the present invention includes a support rod 1 that rotatably supports the sheet paper roll 17.
A locking projection 50 is provided on the outer periphery of one of the support rods 18 of 8 and 18a, and an engagement groove 51 into which the locking projection 50 engages is provided on the roll core R side into which this support rod 18 is fitted. However, when setting the sheet paper roll 17 in the box body 14, the engagement groove 51 provided in the roll core R is inserted into the support rod 18 side having the locking protrusion 50.
position the locking protrusion 50 in this engagement groove 51.
The sheet paper roll 17 may be always set in the same direction by engaging the sheet paper roll 17. By setting the sheet paper roll 17 as described above, the sheet paper 17a is always curled in the winding direction. In the direction of returning the pressure roller 2, as shown in FIG.
It has the advantage that it can be wrapped around the roller 3 and held between the pressure roller 23 and the feed roller 22.
If the sheet paper roll 17 is installed in the wrong direction, the sheet paper 17a may not be able to uncurl, or the pressure roller 23 may not be able to uncurl.
It is possible to avoid a mistake in setting the sheet paper roll 17, in which the sheet paper roll 17 cannot be wrapped around the sheet paper roll.

In addition, when the sheet paper 17a rewound from the sheet paper roll 17 is wound around the pressure roller 23, in order to check whether it has been wound correctly, for example, a hinge piece that supports the paper feed opening 20 or the toilet seat 12 is used. In such areas, an indicator (not shown) is provided at a position corresponding to the width dimension when the sheet paper 17a is normally fed out,
Sheet paper 1 wrapped around the pressure roller 23
By aligning both sides of the feeding portion of the sheet paper 7a with the above-mentioned indicators and returning the pressure roller 23 to the feeding roller 22 side, the sheet paper 17a can be accurately clamped and the feeding position of the sheet paper 17a may be misaligned or loosened during paper feeding. The present invention can also be achieved by preventing the occurrence of such problems.

[Effect of idea]

Since the present invention is constructed as described above, when replacing the sheet paper roll, after setting the sheet paper roll between the support plates in the same way as when installing toilet paper, The sheet paper is pulled out from the center around the pivot point, and the sheet paper fed out from the sheet paper roll is wound around the pressure roller provided on the support plate, and the support plate is returned to the box body. Since the sheet paper roll can be easily held between the sheet paper roll and the pressing roller, the sheet paper roll can be quickly and easily replaced by almost one operation.

In addition, since the pressure roller is attached to the support plate, simply swing the support plate toward the toilet seat.
It is now possible to easily bring the sheet paper into contact with and separate from the feed roller, and the sheet paper fed from the sheet paper roll can be smoothly and easily fed out without causing any slack or tangles, and can be held between the pressure roller and the sheet paper. Even if a problem such as a sheet paper jam occurs between the two rollers, the press roller can be separated from the feeding roller by swinging a pair of support plates pivotally attached to the box toward the front of the box. This makes it possible to easily remove paper jams in sheet paper, and to quickly and reliably correct troubles such as paper jams.

Furthermore, when replacing the sheet paper roll, the support plate pulls out the pressure roller toward you, so paper dust and chips generated when cutting the sheet paper adhere to the pressure and feed rollers or the movable plate. This has the advantage that cleaning, maintenance and inspection of the automatic sheet paper supplying toilet seat can be easily performed even if the toilet seat is in use.
