Description

The present invention relates to an apparatus for automatically supplying sheet paper covering an upper surface of a toilet seat body, and has an object to smoothly cover a toilet seat from a sheet paper roll. The present invention is to provide a sheet paper automatic feeding toilet seat which is fed out and satisfactorily cuts the fed one sheet of paper and lays it on a toilet seat body.

[Conventional technology]

In recent years, when using Western style toilets, as a device to spread sheet paper on the toilet seat in consideration of hygiene, for example,
A cover supply device for a toilet seat described in JP-A-60-155399 is found.

The device is shaped and shaped to cover the upper surface of the toilet seat body, and is wound into a continuous sheet paper roll in a sheet shape and housed in a protective cover. A paper holder for supporting the sheet paper roll so that the sheet paper roll can be continuously fed, a feeding roller device for feeding the sheet paper fed from the sheet paper roll a predetermined length forward near the upper surface of the toilet seat body, And a cutting device provided with a cutting blade for cutting the rear end of the sheet paper fed by a predetermined amount onto the toilet seat body.

In such a conventional device, the feeding and cutting operations of the sheet paper are performed by turning on an operation switch, starting an electric motor, and feeding the sheet paper to a length covering the toilet seat body by the feeding roller device. Was driven by another electric motor of a cutting device consisting of: to cut one sheet of sheet paper. As described above, when using a Western-style toilet, the user can use the Western-style toilet in a sanitary manner because the sheet paper can be automatically spread on the toilet seat body and seated.

[Problems to be solved by the invention]

However, the toilet seat cover supply device having the above configuration has the following problems.

(1). The sheet paper fed out on the toilet seat body is a soft thin leaf that can be washed and discarded, and it is manufactured in a large format to cover the toilet seat body, so it is very stiff,
Moreover, since the sheet paper is rich in water absorption, it is extremely difficult to cut the sheet paper unwound from the sheet paper roll and fed onto the toilet seat body. That is, although one of the sheet papers fed onto the toilet seat is pinched by the feed roller device, the other located on the toilet seat body has no pinching means, so that a cutting point of the sheet paper is possible at the time of cutting. In some cases, cutting could not be performed smoothly due to biting between the blade and the fixed blade.

(2) Since no means for supporting the sheet paper fed from the sheet paper roll is provided between the assembly roller device and the cutting blade, the cut end on the sheet paper roll side is fixed after cutting. Since it is only mounted on the blade, if the vicinity of the cut end is curled due to curling, it will not be mounted on the fixed blade, curl in the winding direction, and at the time of feeding, the cutting blade etc. And paper jams easily occur, and it is difficult to smoothly feed the sheet paper onto the toilet seat body.

(3) Further, since the cutting device for cutting the sheet paper is often mounted just inside the paper feed port opening on the toilet seat body side due to the configuration of the cover feeding device, the rebound of sewage adheres. In addition, it was easy and unsanitary, and the blade portion was rusted due to the adhesion of the sewage, so that the sheet paper could not be cut smoothly.

(4) In addition, since the toilet seat cover feeding device drives the sheet paper feeding roller device and the cutting device with respective electric motors, the control for separately controlling both electric motors is performed. Since the apparatus is required and two electric motors are used, there is a problem that the product cost is increased. In addition, the power consumption is increased due to the drive of two motors, and a specially required electric equipment is required, which is very uneconomical.

In view of the above problems, the present invention performs only the feeding of the sheet paper by a paper feeding mechanism that is electrically driven, and the cutting of the length of the fed sheet paper covering the toilet seat is performed using the weight of the user. By lowering the toilet seat body, the paper cutting mechanism operates, and
It is an object of the present invention to provide a sheet paper automatic supply toilet seat having a simple configuration in which a perforation provided in a sheet paper is torn.

[Means for solving the problem]

According to the present invention, a sheet paper unwound from a sheet paper roll is sandwiched between a feeding roller and a pressing roller at a lower portion in a casing on which the sheet paper roll is rotatably mounted, and the feeding roller is a dry battery or a storage battery. A paper assembling mechanism is provided which rotates a motor driven by a battery power supply to feed out the sheet paper, and a lifting / lowering movement of a toilet seat body having a pivot portion formed vertically movable at a front side of the paper feeding mechanism. Into a circular motion by a lever, a cam member that turns, a slide member that first moves upward by the rotation of the cam member, and then moves in the horizontal direction, and is rotatable above the slide member. Placed,
While holding the sheet paper with the slide member in response to the upward movement and the horizontal movement of the slide member, a holding member that rotates following the slide member to form a perforation provided with the sheet paper at the cutting position. It is characterized by having a paper cutting mechanism for tearing and cutting.

[Operation] According to the present invention, when feeding the sheet paper based on the above configuration, the paper feeding mechanism is driven by a battery power source such as a dry battery or a storage battery, and the sheet paper continuous from the sheet paper roll is covered on the toilet seat body by a length. Then, when the user sits on the toilet seat main body, the pivot portion of the toilet seat main body descends due to the weight of the user, and the cam member is rotated by the lever with the downward movement, and the rotation of the cam member is performed. The slide member provided so as to be able to come in contact with and separate from this is once raised, and the sheet paper is sandwiched between the slide member and the holding member.
A part of the slide member is clamped at two points in front and rear of the sheet paper feeding direction, and one of the holding points, that is, a holding point on the sheet paper feeding direction side, is rotated by using a cam member. Horizontally, the sheet paper is pulled in the feeding direction, the perforation of the sheet paper is torn, and one sheet of paper laid on the toilet seat body is cut. Cutting by using the weight reduces the cutting load, and places where it is difficult for this type of toilet seat to pull in the wiring of the electric motor power supply, for example, a public toilet, or a place where an existing Western-style toilet such as a hotel or restaurant is installed In addition, the power supply equipment can be easily installed without any special draw-in.
In addition, since the motor only needs to operate the paper feeding mechanism by the battery power source, only one motor is required, and furthermore, the motor control device can be simplified by controlling only the motor of the paper feeding mechanism. Thus, the sheet paper automatic feeding toilet seat can be economically manufactured with a simple structure in combination with not using a cutting blade.
In addition, since the cutting blade is not used, there is no member that hinders the feeding of the sheet paper during feeding, and the sheet paper is fed smoothly and favorably to the toilet seat body without causing paper jams or entanglement. In addition, since the driving source for feeding the sheet paper uses a battery, electrical safety can be improved.

 Next, the operation will be described.

When feeding the sheet paper P, the paper feed switch 52 is pressed and the electric motor 20 is driven by the battery power supply 22. When the electric motor 20 is driven, the feeding roller 23 rotates at a reduced speed via the speed reduction device 25, and the sheet paper P sandwiched between the pressing roller 24 and the sheet paper P is rewound from the sheet paper roll R while the paper delivery path 32 → paper feeding outlet 46. When the sheet paper P is further fed out onto the toilet seat main body 5 and the sheet paper P almost covers the toilet seat main body 5, that is, when the sheet paper P is fed out corresponding to the length of one sheet, the position detecting through hole 50 is provided. Reaches the position of the paper position detection sensor 51, and when the through hole 50 is detected by the sensor 51, a detection signal is sent to the control device 21, and from this signal, the control device 21 outputs a stop signal programmed to the microprocessor MPU. A signal is sent to the drive circuit 58 to stop the motor 20. Therefore, the paper feeding mechanism 8 stops feeding the sheet paper P. At this time, the perforation 61 of the sheet paper P is set so as to be located between the paper holding members 35 and 35a of the paper cutting mechanism 9.

Next, the case where the sheet paper P fed out onto the toilet seat main body 5 is separated from the sheet paper roll R will be described.

When the user sits on the toilet seat main body 5, the rear portion of the toilet seat main body 5 descends against the force of the compression spring 14 to operate the paper cutting mechanism 9, as shown in FIGS. That is, the pivots 6, 6a descend along the guide grooves 11b of the inner wall 11a of the lower casing 7a and the guide grooves 16, 16 of the elevating guide boxes 12, 12. The operation contents of the cutting mechanism 9 will be described in detail. At the same time as the toilet seat main body 5, the operating lever 43 also lowers on the pivots 6 and 6 a around the shaft rod 41 according to the weight of the user. Then, the actuating lever 43 is FIG. 4, when lowered to t ₁ point of the pivot 6, shaft rod secures the fulcrum of the actuating lever 43 41
4 rotates counterclockwise in FIG. 4 to rotate the cam member 42 supported on the shaft 41 in the same direction by an angle corresponding to the amount of the lowering of the operating lever 43 and engage with the first cam groove d. The engaging roller 39 of the sliding member 17 is moved to the second cam groove e as shown in FIG. The engagement roller 39 is a cam member 42
When the slide member 17 is pushed up by the rotation of the second cam groove e and moves to the second cam groove e, the slide member 17 moves together with the storage frame 33 in the upward movement range of the engagement roller 39 as shown in FIG. , Is pushed toward the paper delivery path 32, and the paper delivery path 32 is pressed.
As shown in FIG. 5, the sheet holding member protruding into the paper delivery path 32 has the sheet paper P fed therein.
35, 35a, the lower end surface of the machine frame 29 provided at the lower end of the hanging support machine frame 30 corresponding to the paper holding members 35, 35a, and the swing plate 36.
Between the projections 36a. Then, the toilet seat main body 5 is further lowered, and the operating lever 43 is moved to t ₂ of the pivot 6 in FIG.
When lowered to the point, the actuating lever 43 with the descending from t ₁ point pivot 6 to t ₂ points, corresponding to the angle by further rotating the cam member 42支着the shaft rod 41 to the drop of the actuating lever 43 Let it. Therefore, as shown in FIG. 6, the slide member 17 is linearly moved from the position shown in FIG. 5 to the paper feeding port 46 along the storage frame 33 via the engagement roller 39 against the force of the spring 34. Slide. As the slide member 17 slides, a paper holding member provided on the slide member 17
35 is in contact with the projection 36a of the swing plate 36 via the sheet paper P, so that the swing plate 36
It is rotated clockwise in FIG. 5 around 36b. On the other hand, the storage frame 33 is urged toward the machine frame 29 of the suspension support frame 30 via the slide member 17 despite the rotation of the cam member 42, that is, the slide member 17 By rotating the cam member 42 in a range where the operation does not release the pressing of the storage frame 33, the paper holding member 35a provided on the storage frame 33 side moves the sheet paper P between the lower end surface of the machine frame 29. It keeps pinching.

As described above, when the user sits on the toilet seat main body 5 and rotates the cam member 42 through the operating lever 43 by a certain angle, the sheet paper P in the paper delivery path 32 is
One of the holding points is held by the paper holding member 35a and the machine frame 29 around the perforation 61, and the other holding point is provided by the paper holding member 35 provided on the slide member 17 and the projection 36a of the swing plate 36. With the movement of the slide member 17, the holding portion between the paper holding member 35 and the projection 36a is strongly pulled toward the paper feeding port 46 with the movement of the slide member 17. At this time, swing plate
The protrusion 36a comes into contact with the paper holding member 35 and rotates by the movement of the slide member 17 to strongly press the paper holding member 35, so that the sheet paper P can be strongly pulled without forming a slit. As a result, a large tension is applied to the sheet paper P between the paper holding members 35 and 35a, and the holding members 35 and 35
The perforations 61 existing between 5a cut the sheet paper P by being forcibly torn and broken by the tension.

After the cutting of the sheet paper P, as shown in FIG. 6, since the sheet paper P is held by the swinging plate 36 and the paper holding member 35, the user slightly moves the body on the toilet seat body 5. Even if it does, no displacement will occur. Thereafter, the user drops the punching tongue piece 62 of the sheet paper P into the Western toilet 3 while leaving a part of the sheet paper P as shown in FIG.

Note that the punching tongue piece 62 may be made to hang down in the toilet bowl 3 when the sheet paper P is fed out onto the toilet seat main body 5.

When the user leaves the toilet seat body 5 after completing the addition, the toilet seat body 5 is moved by the urging force of the compression springs 14 in the pivot portions 11, 11, so that the pivots 6, 6a are controlled by the regulating plate as shown in FIG.
It is pushed up until it comes into contact with 15, and the toilet seat body 5 is returned to the original position as shown by the solid line in FIG. With the return of the toilet seat body 5 to its original position, the pivot point of the operating lever 43 on the pivots 6 and 6a side also rises, and the shaft rod 41 supported on the other end of the operating lever 43 is rotated clockwise, and the cam member 42 is rotated. To the position in FIG.
The position (original position) before the sheet paper P shown in FIG. 4 is sandwiched from the position where the sheet paper P fed out onto the toilet seat main body 5 by sliding the slide member 17 is sandwiched.
And the sheet paper P is released. On this occasion,
The engagement roller 39 of the slide member 17 moves from the second cam groove e of the cam member 42 to the first cam groove d side to engage therewith, retreats the slide member 17 by the spring 34, and Body 33
Is released, and the paper holding members 35, 35a are immersed from the paper delivery path 32 into the space a of the inclined ceiling wall 17a so as not to hinder the feeding of the next sheet paper P. Further, since the swing plate 36 is released from contact with the paper holding member 35 by the retreat of the slide member 17, the swing plate 36 rotates to the original position side by the force of the spring member 37 and the regulating portion of the machine frame 29.
38, the paper delivery path 32 is opened so as not to hinder the passage of the sheet paper P.

Note that the sheet paper P fed out onto the toilet seat body 5 is released when the user leaves the toilet seat body 5, so that when the washing water flows into the Western toilet 3 in this state,
The punching tongue pieces 62 already submerged in the toilet bowl 3 are drawn into the toilet bowl 3 by the flushing water, and the sheet paper P on the toilet seat body 5 is automatically pulled into the toilet bowl 3 to remove sewage. Let them drain together.

When the next user needs the sheet paper P again, the same operation as described above may be performed.

Also, if the paper feeding switch 52 is accidentally turned on during seating, a program is set in the memory 56 so that a drive command is not sent to the electric motor 20 while the seating detecting means 53 detects seating. In addition, it is possible to prevent an accident that the next sheet paper P is unexpectedly fed out while sitting and causes a paper jam in the paper delivery path 32.

Further, at the time of feeding out the sheet paper P, a portion where the paper holding members 35 and 35a do not exist on the upper surface of the installation space a of the inclined ceiling wall 17a is closed by the paper guide plate 44, and
A projection 36 of a swinging plate 36 is provided on the lower surface of the machine frame 29 of the suspension frame 30.
Since the paper jam prevention plate 45 is attached except for the portion through which a can pass, the sheet paper P fed out to the paper delivery path 32 is smoothly guided by the paper guide 44 plate and the paper jam prevention plate 45. Feeding without paper jam.

In addition, if a paper jam occurs in the paper delivery path 32 during the feeding of the sheet paper P, in this embodiment, the time required for feeding the sheet paper P is set by the timer 57. Even if it passes, if the paper position detection sensor 51 does not detect the through hole 50 of the sheet paper P,
The paper trouble lamp 64 shown in FIG. 1 is turned on to determine that a paper jam has occurred or that there is no paper, so that the user can be notified that a paper jam or the like has occurred.

〔The invention's effect〕

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

(1) The present invention is configured to cut a perforated sheet of sheet paper fixedly fed onto a toilet seat body without using a cutter for cutting by utilizing a weight when a user sits on the toilet seat body. Therefore, the sheet paper can be cut quickly and reliably by using the perforations, as compared with a conventional cutter having a cutter.

(2) Further, the mechanism for breaking the perforation of the sheet paper uses an operating lever to move the lifting / lowering motion of the toilet seat body that moves downward by the weight of the user instead of the electrically driven cutting cutter as in the related art. Since a mechanism for cutting the sheet paper is adopted by a simple structure in which the slide member is driven by converting the rotation into a rotational motion, the sheet paper cutting mechanism can be manufactured simply and economically. .

(3) In addition, the sheet paper cutting mechanism is designed so that the user can enter and exit the paper delivery path by utilizing the point that the weight effect when the user sits on the toilet seat body and the weight effect when the user leaves the seat cannot be obtained. When the sheet paper is fed out, the paper delivery path does not include a member such as a cutting cutter that hinders the feeding of the sheet paper as in the related art. Sheet paper can be smoothly and satisfactorily fed out.

(4) Further, since the present invention employs a structure in which only the paper feeding mechanism is driven by an electric motor, it is possible to use a battery such as a dry battery or a storage battery as a driving power source for the electric motor. It can be easily attached to a Western-style toilet installed in an inadequate public toilet or the like, and can be downsized with the simplification of the configuration of the sheet paper automatic supply toilet seat itself, and there is an advantage that the manufacturing cost of the toilet seat can be reduced.
