Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a toilet seat that is equipped with a device that automatically supplies sheet paper for hygienically covering the toilet seat of a Western-style toilet bowl, and its purpose is to To quickly and surely fix the sheet paper so that it does not loosen when cutting the sheet paper fed out from a paper roll onto a toilet seat, and to perform the cutting operation smoothly and well.

[Conventional technology]

In recent years, many Western-style toilets have come into use in hotels, restaurants, and general households. Since this Western-style toilet bowl 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, to prevent the toilet seats from becoming unsanitary. 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,
On the contrary, attaching a cloth cover to the toilet seat makes it easy to overlook the adhesion of sewage, which may even exacerbate unsanitary conditions. Furthermore, unlike in ordinary homes, toilet seat covers are not usually used at all in Western-style toilets installed in public places used by an unspecified number of people, such as hotels, restaurants, and various types of transportation. Yes, but it is the same as when a cloth cover is attached in that sewage droplets directly adhere to the toilet seat. On top of that,
The use of such toilet seats by an unspecified number of people is a major public health problem, and the desire to use Western-style toilets installed in public places in a hygienic manner is increasing day by day. It is worshiped.

For this reason, recently, sheet paper is fed out using an electrically driven roller and laid on the toilet seat, and then cut by a cutting blade.In other words, the sheet paper is automatically fed out onto the top of the toilet seat, allowing Western-style toilets to be used hygienically. For example, a toilet seat made in the 1980s.
155399, and its schematic structure will be explained with reference to FIG. 13. 1 is a toilet bowl, 2 is a toilet seat mounted on the toilet bowl 1 so that it can be raised and lowered, 3 is a paper holder, and there is a sheet inside. paper roll 4
is rotatably stored. Reference numeral 5 denotes a feed-out cutting section that feeds out the sheet paper 4a rewound from the holder 3 onto the toilet seat 2 and cuts it into a predetermined length. Set of delivery rollers 7
a, 7b and cutting blades 8a, 8b for cutting the sheet paper 4a are attached, and the delivery roller 7a and the cutting blade 8a are individually driven and connected by an electric motor (not shown). The Western-style toilet bowl 1 can be used hygienically by sitting on the toilet seat 2 via the sheet paper 4a that has been rewound from the sheet paper 4a and fed out a certain length onto the toilet seat 2.

[Problem to be solved by the invention]

However, as mentioned above, the sheet paper 4a that is fed out to a predetermined length onto the toilet seat 2 from the sheet paper roll 4 and cut is generally made of a soft thin sheet so that it can be disposed of by washing with water, so it is very difficult to use. It is weak and highly hygroscopic, and is large in size to cover the entire top surface of the toilet seat 2. Moreover, during cutting, one side of the sheet paper 4a is held between the delivery rollers 7a and 7b, but the other side, which is fed out onto the toilet seat 2, is not provided with any holding or pressing means. Therefore, in the structure in which the sheet paper 4a is cut by raising and lowering the cutting blade 8a as described above, the sheet paper 4a that has been fed out to the toilet seat 2 side is pulled back to the mounting base 5a side. That is, it often gets stuck between the cutting blades 8a and 8b, leaving uncut portions on the sheet paper 4a, making it difficult to cut smoothly. In this case, it is considered possible to cut the paper 4a if the user holds the sheet paper 4a fed out onto the toilet seat 2 by hand or sits on the toilet seat 2, for example, to fix the paper 4a. However, it is completely impossible to request this from an unspecified number of users who use Western-style toilets.

Further, among the delivery rollers 7a and 7b that feed out the sheet paper 4a, one delivery roller 7b that is not connected to the electric motor is brought into sliding contact with the other delivery roller 7a that is driven by an electric motor so that it can simply rotate. Therefore, even if the sheet paper 4a fed out onto the toilet seat 2 could be fixed by some means during cutting, the cutting blade 8a, 8
When the sharpness of b becomes worse, the delivery rollers 7a,
The paper on the 7b side is
Due to incomplete nipping by (feeding roller 7
As above, as the cutting blade 8a descends, the cutting blades 8a, 8a are pulled without being cut, and
8b and could not be cut smoothly.

In this way, the large size and weak sheet paper 4
There are many problems in cutting the sheet paper 4a by the lifting and lowering action of the cutting blade.Furthermore, if the sheet paper 4a fed out onto the toilet seat 2 is incompletely cut, the sheet paper 4a may not be cut into the toilet bowl 1 after use. It is extremely unsanitary if the toilet seat 2 cannot be automatically disposed of and is left as is on the toilet seat 2. Also, if you try to forcefully pull the sheet paper 4a and try to eject it, it will not be a big problem if there is only a small amount of uncut parts, but if you forcefully pull the sheet paper 4a when there are almost no uncut parts, it will be torn off by the sandwiched part of the delivery rollers 7a and 7b. Otherwise, the feed roller 7b may be pulled out excessively and break due to idle rotation of the feed roller 7b.
Because the sheet paper 4a is not cut smoothly, the sheet paper 4a becomes unnecessary for the user.
This made it necessary to clean up after the toilet seat, which was a major obstacle to the widespread use of this type of toilet seat.

In view of the above-mentioned problems, the present invention provides an automatic sheet paper supply toilet seat that is configured to clamp and fix the sheet paper in an optimal state for cutting when cutting the sheet paper, so that the sheet paper can be cut quickly and reliably. purpose.

[Means to solve the problem]

The present invention includes a box body that houses a sheet paper roll, and a dispensing member consisting of a dispensing roller and a pressure roller that clamps the sheet paper and dispenses it in a fixed amount onto the toilet seat, and a movable plate that smoothly guides the dispensing of the sheet paper onto the toilet seat. and a breaking protrusion arranged corresponding to the movable plate to sandwich one side of the sheet paper between the movable plate and to cut the sheet paper from the perforation on the opposite side that does not sandwich the sheet paper. a rotating plate with Centering on the perforation of the sheet paper, one side is held between a movable plate and a rotating plate, and the other is held between a feeding and pressing roller, and just before the perforation of the sheet paper is torn, a spring member is attached. The present invention relates to an automatic sheet paper feeding toilet seat in which the pressing roller is strongly pressed against the feeding roller side by force, and the perforation is smoothly broken at the breaking protrusion.

[Effect]

When cutting sheet paper, the present invention rotates the movable plate toward the rotating plate to sandwich one side of the sheet paper, and the other side of the sheet paper is pinched by the feeding and pressing rollers, and in this state, the movable plate is further held. The sheet paper is rotated and a predetermined tension is applied to the sheet paper between the two points sandwiching the sheet paper, and the movable plate rotates the rotary plate toward the sheet paper side, and immediately before the perforation is broken by the breaking protrusion. A further feature is that the pressing roller is strongly urged toward the feeding roller by a spring member attached to the rotary plate, so that the sheet paper can be smoothly and well torn from the perforation and broken.

A notched groove 24 into which the free end of the spring i fits is cut out to expose the roller shaft 23a, and as the rotating plate 18 rotates, the free end of the pressure spring i biases the roller shaft 23a. to press the pressure roller 23 toward the feeding roller 21 side. At this time, as shown in FIG. 11, the roller shaft 23a of the pressure roller 23 is inserted through a long hole 25 in the support plates 15, 15a, which is perforated diagonally downward toward the paper feeding port 20. Because there are
In FIG. 11, the pressing roller 23 is pressed parallel to the elongated hole 25, that is, toward the lower left in the figure, in such a manner that it bites into the feeding roller 21, as shown in FIG. The sheet paper 17a rewound from the sheet paper roll 17 is held between the feed roller 21 and the pressure roller 23, and is fed out in a fixed amount from the paper feed opening 20 onto the toilet seat 12 by driving the feed roller 21. 26 is a movable plate that forms a feeding path 27 for the sheet paper 17a, which is disposed below the rotating plate 18 and between the feeding roller 21 and the paper feeding port 20;

Instead of being provided on the top surface of the end box 14a, it may be attached to the back side of the end box 14a, if necessary. or,
The sheet paper 17a shown in FIG. 12 is provided with perforations 39 for each length of one sheet fed out onto the toilet seat 12, and which correspond to the openings 12a when fed out onto the toilet seat 12. At each position, a punched piece 40 of a size corresponding to the opening 12a is provided with a portion left uncut.

Note that when the sensor 34 detects the through hole 35 of the sheet paper 17a, the sheet paper 1
7a is fed out to a length that covers the toilet seat 12 in a good manner, and the perforation 39 is set to be located between the breaking protrusion 19 of the rotating plate 18 and the feeding roller 21.

Next, the operation will be explained.

When the feeding device 13 is not in use, the paper outlet 20 is kept closed at one end of the movable plate 26 and the box body 14 is closed, as shown in FIG.
This prevents cleaning water and pollution from entering the interior.

When feeding the sheet paper 17a onto the toilet seat 12, turn on the power switch 37 and check whether the power lamp 38 is lit. After checking, when the paper feed switch 36 is turned on and the electric motor 31 is started, the drive cam 29 of the feeding device 13 rotates clockwise in FIG.
is rotated counterclockwise about the pivot shaft j to a position parallel to the paper delivery path 27 as shown in FIG. 4, and the electric motor 31 is once stopped by a command from the control device S. After that, the electric motor 22 is started by a command from the control device S, drives the feeding roller 21, and unwinds the sheet paper 17a held between the feeding roller 21 and the pressing roller 23 from the sheet paper roll 17. Paper delivery path 2
While feeding out the top of the movable plate 26 forming the toilet seat 7, it is fed out from the feeding opening 20 onto the toilet seat 12. As described above, when the sheet paper 27a is fed out to a length that covers the toilet seat 12, the sheet paper 17
The through hole 35 of a reaches above the sensor 34 and is detected,
Based on the detection signal, a command to stop the electric motor 22 is output from the control device S, and the sheet paper 17 is
Finish feeding out a. After this, the electric motor 31 is started again by a command from the control device S, and the drive cam 29
The movable plate 26, which is parallel to the paper delivery path 27 by rotating the
It rotates toward the rotation plate 18 in a state perpendicular to the paper delivery path 27 about the center. Due to this rotation of the movable plate 26, the sheet paper 17a located on the feeding roller 21 side is moved by the movable plate 26.
It is lifted toward the rotating plate 18 side by one end of the rotating plate 6, and is held between the pressing pieces f and n. In this state, the drive cam 29 continues to rotate, rotating the movable plate 26 toward the rotating plate 18, and rotating the rotating plate 18 clockwise in FIG. 6 about the axis e. As a result, the sheet paper 17a is firmly held between the pressing pieces f and n, and the breaking protrusion 19 comes into contact with the sheet paper 17a. At this time, as shown in FIG. Press the shaft 23a lightly. However, when the drive cam 29 continues to rotate and reaches a point where it has rotated about half a turn from the starting point, the movable plate 26 tilts to its maximum extent. Therefore, the rotating plate 18 similarly rotates, and the free end of the pressing spring i exerts its elastic force to the maximum to firmly press and urge the roller shaft 23a. As a result, the sheet paper 17a, in FIG.
It will be strongly pulled toward the movable plate 26 side. In this case, the pressing roller 23 and the feeding roller 21
The sliding contact portion is such that the pressure roller 23 moves slightly in the feeding direction of the sheet paper 17a along the elongated hole 25 due to the spring pressure of the pressure spring i, and bites onto the feeding roller 21. Since the sheet paper 17a existing between the movable plate 26 and the feeding roller 21 is not rotated in the state and is pressed with a large frictional force, it is pulled toward the movable plate 26 as described above. too,
Since the press roller 23 can be firmly clamped without idling or sliding from the sandwiched portion with the feed roller 21, the sheet paper 17a located between the movable plate 26 and the feed roller 21 has a large Tension can be added. Therefore, the breaking protrusion 19 provided on the rotating plate 18 rotated by the movable plate 26 presses the portion that is already in contact with the sheet paper 17a more strongly than other portions, so that the sheet paper 1
7a, the perforation 39 near the breaking protrusion 19 is caused by the addition of the large tension.
As shown in FIG. 7, the sheet paper 17a that cannot withstand the pressing force of the breaking protrusion 19 is easily torn from that part and can be quickly, easily, and reliably made into one piece of sheet paper 17a that can be placed on the toilet seat 12. Can be cut.

When the cutting of the sheet paper 17a is completed, the electric motor 31 is stopped by a command from the control device S.
As shown in FIG. 7, the movable plate 26 and the rotating plate 18 prevent the sheet paper 17a from sliding off the toilet seat 12. For this reason,
Even when the user sits on the toilet seat 12 or moves his/her body a little to correct his/her posture after sitting, the sheet paper 17a does not shift from the toilet seat 12. When in use, as shown in FIG. 2, the punched piece 40 is hung inside the toilet bowl 11, and is seated on the toilet seat 12 via the sheet paper 17a to fill the toilet bowl.

When the user leaves the toilet seat 12 after relieving himself or herself, the control device S issues a drive command to the electric motor 31 using a seating detection means (not shown), and rotates the drive cam 29 clockwise again. At this time, the drive cam 29 rotates from the highest position to the lowest position, so the movable plate 26 also retreats toward the original position, and the rotating plate 18 is also pressed by the rotating plate 26. is gradually released, and returns to the direction of the stopper h, that is, to the original position, by the force of the spring g, and releases the pinched state of the sheet paper 17a. Note that when the user leaves the toilet seat 12, the sheet paper 17a is still attached to the movable plate 2.
6 and the rotating plate 18, so it does not get wrapped around the buttocks. Thereafter, the inside of the toilet bowl 11 is cleaned by operating a cleaning device (not shown), and the punched piece 40 of the sheet paper 17a is dragged into the toilet bowl 11 by the force of the cleaning water, and the sheet paper 17a is discharged together with the dirty water. On the other hand, the drive cam 29 continues to rotate, and when it returns to the starting point as shown in FIG. 3, the electric motor 31 is stopped by a command from the control device S and the rotation is stopped. Therefore, the movable plate 26 returns to its original position and closes the paper outlet 20. After this, when the next user subsequently uses the Western-style toilet bowl 11 by feeding out the sheet paper 17a, the same operation as described above can be performed. At this time, as shown in FIG. 3, the rotating plate 18 has been returned to its original position by the spring g, and the pressure on the pressure roller 23 by the pressure spring i has been released, so the pressure roller 23 is 21, the sheet paper 17a can be fed out quickly and reliably.

〔Effect of the invention〕

Since the present invention is configured as described above, it has the following effects.

(1) The present invention is completely different from the conventional cutting blade that moves up and down to cut soft thin and large sheet paper, which leaves uncut parts on the sheet paper. The structure is such that the sheet paper on both sides of the sheet paper is firmly held around the perforation, which is the cutting position of the sheet paper, and a large tension is applied to the sheet paper itself to cut the perforation. To cut sheet paper fed onto a toilet seat smoothly, efficiently, and reliably without forcing any necessary operations.

(2) In particular, the pressure roller, which feeds out the sheet paper together with the feed roller, is configured so that when cutting the sheet paper, the free end of the spring member fixed to the rotating plate firmly presses the sheet paper against the feed roller. Therefore, when applying tension to the sheet paper, it is possible to reliably prevent the sheet paper from sliding from the sandwiched part between the feeding roller and the pressing roller due to the idling of the pressing roller. It is possible to add a large amount of paper and reliably, and the sheet paper can be cut quickly and easily.

(3) Also, the spring member is configured so as not to press the pressure roller unnecessarily when the rotating plate returns to its original position (when not cutting the sheet paper), so the sheet paper The sheet paper can be held between the feeding roller and the pressing roller with a force suitable for feeding, which has the advantage that the sheet paper can be fed smoothly without requiring a large drive.
