Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for automatically feeding sheet paper to cover the top surface of a toilet seat body, and its purpose is to smoothly supply a length of sheet paper to cover the top of the toilet seat from a sheet paper roll. To provide an automatic sheet paper supplying toilet seat which is fed out, and in which the fed sheet paper is neatly cut and laid on the toilet main body.

[Conventional technology]

In recent years, when using a Western-style toilet, a device for laying sheet paper on the toilet seat in consideration of hygiene has been introduced, for example, in 1983.
The toilet seat cover supply device described in Japanese Patent No. 0-155399 can be seen.

The device is shaped and sized to cover the top surface of the toilet seat body, and is rolled up into a continuous sheet paper roll in a sorted manner and housed in a protective cover. a paper holder that supports the sheet paper roll so that it can be continuously fed out;
A feeding roller device for feeding the sheet paper fed out from the sheet paper roll forward by a predetermined length near the top surface of the toilet seat body; and a feeding roller device for cutting the rear end of the sheet paper fed out by a predetermined amount onto the toilet seat body. It consists of a cutting device equipped with a cutting blade.

In such conventional devices, sheet paper feeding and cutting operations are performed by turning on an operation switch to start an electric motor, and
After the sheet paper is fed out to a length that covers the toilet seat body by the feeding roller device, a cutting device consisting of a movable blade and a fixed blade is driven by another electric motor to cut the -sheet paper. As mentioned above, when using a Western-style toilet, the user can automatically spread sheet paper on the toilet seat body and sit on it, allowing the user to use the Western-style toilet hygienically.

[Invention or problem to be solved]

However, in the toilet seat cover supply device having the above configuration,
There was a problem as shown below.

(1) The sheet paper fed onto the toilet seat body is
It is made of soft, thin leaves that can be disposed of by flushing, and is made in a large size to cover the top of the toilet seat itself, making it extremely fragile and highly absorbent, so it is unwound from the sheet paper roll and is used to cover the toilet seat itself. Cutting the sheet paper fed out on top was extremely difficult. That is, although one side of the sheet paper fed out onto the toilet seat is held by the feeding roller device, the other side located on the toilet seat body has no holding means at all, so when cutting, the cutting part of the sort paper or the movable blade Sometimes it got stuck between the blade and the fixed blade, making it difficult to cut smoothly.

(2) Also, since there is no means to support the sheet paper fed out from the sheet paper roll between the feeding roller device and the cutting blade, after cutting, the cut end on the sheet paper roll side is connected to the fixed blade. Since it is only placed on top of the blade, if it is curled near the cutting edge due to the curl, it will not be placed on the fixed blade and will curl in the direction of the curl, causing the cutting blade etc. It was easy to get tangled and cause paper jams, and it was difficult to smoothly feed the sheet paper onto the toilet seat body.

(3) Furthermore, due to the structure of the cover supply device, the cutting device that cuts the sheet paper is often installed just inside the paper feed opening that opens on the toilet seat body side, so sewage may splash or adhere to the sheet paper. In addition to being easy to clean and unsanitary, the blade part may rust due to the adhesion of the sewage, making it impossible to cut the sheet paper smoothly.

(4) Furthermore, in the toilet seat cover supply device, since the sheet paper feeding roller device and the cutting device are each driven by separate electric motors, it is difficult to control the two layers separately. Since a control device is required and two electric motors are used, there is a problem of increasing product cost. Moreover, power consumption increases because two electric motors are driven, and special power supply equipment is required for this purpose, which is extremely uneconomical.

In view of the above-mentioned problems, the present invention uses an electrically driven paper feeding mechanism to feed out only the sheet paper, and cuts the sheet paper fed out to a length that covers the toilet seat.
To provide an automatic sheet paper supplying toilet seat having a simple structure in which a paper cutting mechanism is operated by lowering the toilet seat body using the user's weight to tear the perforations provided in the sheet paper. The purpose is to

[Means to solve the problem]

The present invention is characterized in that sheet paper unwound from the sheet paper roll is held between a feeding roller and a pressing roller in the lower part of a casing in which a sheet paper roll is rotatably mounted, and the feeding roller is connected to a dry battery, a storage battery, etc. A paper dispensing mechanism is provided, which is rotated by an electric motor driven by a battery power source to dispense sheet paper, and the front side of this paper dispensing mechanism is equipped with a pivot part that can move up and down to control the vertical movement of the toilet seat body. A cam member that rotates by converting it into a circular motion by a lever, a slide member that first moves upward and then moves horizontally as the skeleton cam member rotates, and a slide member that is rotatably arranged above the slide member. The sheet paper is placed at the cutting position by a holding member that rotates following the slide member while holding the sheet paper with the slide member in response to the upward and horizontal movement of the slide member. The paper is characterized by being equipped with a paper cutting mechanism that tears the perforations and cuts the paper.

[For production]

The present invention is based on the above-mentioned configuration, and when feeding sheet paper, the paper feeding mechanism is driven by a battery power source such as a dry battery or a storage battery, and a length that covers the sheet paper t-1 continuous from the sheet paper roll is placed on the main body of the sheet paper T-1. After this, when a user sits on the toilet seat body, the pivot part of the toilet seat body descends due to the user's weight, and in conjunction with this descending movement, the cam member is rotated by a lever, causing the rotation of the cam member. The slide member which is provided so as to be able to come into contact with and separate from this is once raised, and the sheet paper is placed between it and the holding member.
The sheet paper is held at two points, one at the front and the other at the rear in the feeding direction, and one of the holding points, that is, the holding point on the side in the feeding direction of the sheet paper is held at one part of the slide member using rotation of the cam member. The machine moves the sheet horizontally, pulls the sheet paper in the feeding direction, and tears the perforations of the sheet paper to cut a single sheet of sheet paper to be laid on the toilet seat body.The sheet paper is cut by the toilet user. By cutting using the body's weight, the cutting load is reduced, and this type of toilet seat can be used in places where it is difficult to connect the motor power wiring, such as public toilets, or where existing Western-style toilets are installed, such as hotels and restaurants. etc., it can be easily installed without special installation of power supply equipment.

Moreover, since the electric motor only needs to operate the paper feeding mechanism using battery power, only one electric motor is required, and the motor control device can be simplified because it only needs to control the electric motor of the paper feeding mechanism. Therefore, the automatic sheet paper feeding toilet seat has a simple structure and can be manufactured economically since no cutting blade is used. Furthermore, since the cutting blade is not used, there is no member that obstructs the sheet paper being fed out, so the sheet paper is smoothly and well fed to the toilet seat body without paper jams or tangles. Furthermore, since a battery is used as the drive source for feeding out the sheet paper, electrical safety can be improved.

In the figure, reference numeral 37 is a spring member that is wound around the pivot shaft 36b and always biases the swing plate 36 in the counterclockwise direction in FIG.
When the swing plate 36 is not in operation,
It is pressed by the spring member 37 toward the rotation regulating portion 38 and is held so as not to become an obstacle when the sheet paper P passes through the paper delivery path 32 .

As shown in FIG. 4 and FIG. A substantially oval cam member 42 is supported on a shaft rod 41 that is rotatably supported horizontally via a support frame 40.
As shown in FIG. 4, the cam member 42 is drive-coupled to the engagement roller 39 at a portion thereof corresponding to the engagement roller 39, as shown in FIG. Second cam groove d.

It is formed in an arc shape so that it can be engaged with the engagement roller 39. On the other hand, the shaft rod 41 that supports the cam member 42 supports the toilet seat main body 5 as shown in FIGS. 3 and 4.
It is driven and connected by a pivot shaft 6° 6a pivoted to the toilet seat body 5 and an operating lever 43, and when a user sits on the toilet seat body 5, the rear part of the toilet seat body 5 moves as shown by the dashed line in FIG.
The shaft rod 4 moves downward against the biasing force of the compression spring 14.
1 is rotated by the operating lever 43 to operate the paper cutting mechanism 9.

In addition, in FIGS. 3 and 4, 44 indicates the storage frame 33.
A paper guide plate 45 is provided on the installation space a of the inclined ceiling wall 17a fitted with the paper guide plate 45, leaving a space in which the paper holding members 35, 35a can enter and exit the paper delivery path 32. The lower opening of the machine frame 29 is connected to the swing plate 3.
6, a paper jam prevention plate disposed at such a distance that the protrusion 36a can be passed through when the protrusion 36a is rotated; 46 is a paper feed opening opened in the lower casing 7a and communicated with the paper feed path 32; A recessed part is provided on the upper surface of the front end of the inclined ceiling wall 17a located on the side of the paper feeder 46 at a constant interval in the length direction, and if sewage is scattered near the paper feeder 46, the sewage can be drained. This prevents dirty water from forming a groove and remaining near the paper feeding roller 46.

Next, a schematic configuration of the control device 21 that controls the operations of the paper feeding mechanism 8, the sensor, and the detection means will be described.

In FIG. 12, the control device 21 includes a microprocessor MPU and a through hole 50 (see FIG. 1) for position detection provided at each position where the sheet paper P is fed to a length that covers the toilet seat body 5. Connected to control output generation means such as a paper position detection sensor 51 (see Fig. 4) that detects and generates an output, a paper feeding switch 52 (see Fig. 1) provided on the operating section of the casing 7, and a seating detection means 53. an input interface 54 connected to the paper feed mechanism 8, an output interface 55 connected to the paper feed mechanism 8, and a
Memory 56 and timer 57 for storing programs such as stopping
Furthermore, a drive circuit 58 inserted between the output interface 55 and the paper feeding mechanism 8 and this drive circuit 5
8 and a connected power supply circuit 59.

The paper position detection sensor 51 is, for example,
It is made by combining a phototransistor and a photodiode,
It is attached to the machine frame 29 inside the paper feeding port 46, and on the side of the inclined ceiling wall 17a corresponding to the attachment position.
A passage hole 60 is bored through which the light from the sensor 51 passes.

In addition, the sheet paper P has through holes 5 as shown in Figure 1).
A perforation 61 is provided close to 0 and serves as the boundary of the first sheet of sheet paper P, and a portion of the paper is left uncut in the center corresponding to the opening 5a of the toilet seat body 5. A punched tongue piece 62 is provided.

The upper casing 7b is removably connected to the upper edge of the lower casing 7a, and the paper holder 3
1.31 constitutes a storage section for the sheet paper roll R suspended horizontally, and on the front side thereof, as shown in Fig. 4,
A sewage drainage groove 63 is formed by bending the upper edge of the paper outlet 46 into a U-shape.

Next, the operation will be explained.

When feeding out the sheet paper P, the paper feeding switch 52 is pressed and the electric motor 20 is driven by the battery power source 22. When the electric motor 20 is driven, the feed roller 23 rotates at a reduced speed via the speed reduction device 25, and the sheet paper P held between it and the press roller 24 is rewound from the sheet paper roll R to the paper feed path 32 and then the paper is fed out. 046 onto the toilet seat body 5, sheet paper P
When the sheet paper P is fed out to a length that almost covers the top of the toilet seat body 5, that is, the length corresponding to the inspection length, it reaches the position of the through hole 50 for position detection or the paper position detection sensor 51, and the sheet paper P reaches the position of the through hole 50 for position detection or the paper position detection sensor 51. When the sensor 51 detects the through hole 50,
The detection signal is sent to the auxiliary device 21, and this signal causes the control device 21 to send a stop signal programmed in the microprocessor MPU to the drive circuit 58 to start the electric motor 2.
Stop ゜. Therefore, the paper feeding mechanism 8 stops feeding out the sheet paper P(7). At this time, the perforations 61 of the sheet paper P are set 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 onto the toilet seat main body 5 is separated from the sheet paper roll R will be explained.

When the user sits on the toilet seat main body 5, FIG.

As shown in Fig. 6, the compression spring from the rear of the toilet seat body 5
The paper cutting mechanism 9 moves downward against the force of the paper cutting mechanism 9. That is, the pivots 6, 6a or the guide grooves 1)b of the inner wall 1)a of the lower casing 7a and the lifting guide box 12.12.
along the guide groove 16.16. The cutting mechanism 9
To explain the operation in detail, due to the weight of the user, the operating lever 43 also moves down toward the pivot 6.6a using the pivot rod 41 as a fulcrum at the same time as the toilet seat body 5. When the operating lever 43 descends to the point 1+ of the pivot 6 in FIG. 4, the shaft rod 41 fixing the fulcrum side of the operating lever 43 rotates counterclockwise in FIG. The cam member 42 supported on the rod 41 is rotated in the same direction by an angle corresponding to the downward movement of the operating lever 43, and the engagement roller 39 of the slide member 17, which is engaged with the first cam groove d, is rotated in the same direction. As shown in Figure 5, move it to the second cam groove e. When the retaining roller 39 is pushed up by the rotation of the cam member 42 and moves to the second cam groove e, the slide member 17 moves within the arrangement space a together with the storage frame 33 within the upward movement range of the engaging roller 39. As shown in FIG. 5, the paper is pushed toward the paper delivery path 32,
As shown in FIG. 5, the sheet paper P being fed into the paper feeding path 32 is suspended by a paper holding member 35.35a that projects into the paper feeding path 32 and corresponding to the paper holding member 35.35a. The lower end surface of the machine frame 29 provided at the lower end of the support frame 3o and the protrusion 36a of the swing plate 36
sandwiched between. Then, the toilet seat body 5 further descends,
When the operating lever 43 is lowered to the point t of the pivot shaft 6 in FIG. The bar 43 is rotated by an angle corresponding to the descent of the bar 43. Therefore, the slide member 17
As shown in FIG. 6 from the position shown in the figure, it slides linearly against the force of the spring 34 along the storage frame 33 toward the paper feeder 46 via the engagement roller 39. As the slide member 17 slides, the paper holding member 35 provided on the slide member 17 contacts the protrusion 36a of the swing plate 36 via the sheet paper P, so that the swing plate 36 is pivoted. Centered around 36b,
Rotate clockwise in FIG. On the other hand, despite the rotation of the cam member 42, the storage frame body 33 is urged toward the machine frame 29 side of the hanging support frame 30 via the slide member 17. The cam member 4 does not move until the pressure on the storage frame 33 is released.
2, the paper clamping member 35a provided on the side of the storage frame 33 continues to clamp the sheet paper P between it and the lower end surface of the machine frame 29.

As described above, when the user sits on the toilet seat main body 5 and rotates the cam member 42 by a certain angle via the bar 43, the sheet paper P in the paper delivery path 32 is activated.
With the perforation 61 as the center, one clamping point is clamped by the paper clamping member 35a and the machine frame 29, and the other clamping point is clamped by the paper clamping member 35 provided on the slide member 17 and the protrusion 36a of the swing plate 36. Clamped by (
As the slide member 7 moves, the portion held between the paper holding member 35 and the protrusion 36a is strongly pulled toward the paper feeding roller 46. At this time, the rocking plate 36 comes into contact with the protrusion 36a or the paper clamping member 35, rotates as the slide member 17 moves, and strongly presses the paper clamping member 35.
The sheet paper P can be pulled strongly without causing slippage. As a result, a large tension is applied to the sheet paper P between the paper holding members 35.35a, and the perforations 61 existing between the holding members 35.35a are forcibly torn and broken by the tension. By doing this, the sheet paper P is cut.

After cutting the sheet paper P, as shown in FIG.
Since the sheet paper P is held between the swing plate 36 and the paper holding member 35, even if the user slightly moves his or her body on the toilet seat body 5, the sheet paper P will not be misaligned. Thereafter, the user performs errands 17 by hanging the punched tongue piece 62 of the sheet paper P into the Western-style toilet bowl 3, leaving a portion of the sheet paper P as shown in Figure 1).

Note that the punched tongue piece 62 may be suspended 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 main body 5 after relieving himself or herself, the toilet seat main body 5 is moved from the pivots 6, 6a to the regulating plate as shown in FIG. 15, and the toilet seat body 5 is returned to its original position as shown by the solid line in FIG. As the toilet seat main body 5 returns to its original position, the pivot shaft 6 of the operating lever 43.
The pivot point of 6a#f also rises, and the shaft rod 41 supported on the other end of the operating lever 43 is rotated clockwise, and the cam member 4
2 from the position shown in FIG. 6, that is, the position where the sheet paper P fed onto the toilet seat main body 5 is held by sliding the slide member 17, to the position before the sheet paper P is held as shown in FIG. ! (original position) and release the sheet paper P from being held.

At this time, the engagement roller 39 of the slide member 17 moves from the second cam groove e to the first cam groove d of the cam member 42 and engages with it, causing the slide member 17 to retreat by the spring 34, and , release the push-up of the storage frame 33 and move the paper holding member 35.35a from the paper delivery path 32 to the inclined ceiling wall 1.
7a so as not to interfere with feeding out the next sheet paper P. Further, as the slide member 17 retreats, the swing plate 36 is also released from contact with the paper clamping member 35, so it is rotated to the original position by the force of the spring member 37 and is moved to the regulating portion 38 of the machine frame 29. The paper delivery path 32 is opened so as not to obstruct the sheet paper P from passing through.

Note that the sheet paper P fed out onto the toilet seat body 5 is pinched or released when the user moves away from the toilet seat body 5, so if flushing water is poured into the Western-style toilet bowl 3 in this state, it will already be submerged in the toilet bowl 3. The punched tongue piece 62 is drawn into the toilet bowl 3 by the force of the flushing water, and the sheet paper P on the toilet seat body 5 is automatically pulled into the toilet bowl 3 and discharged together with the dirty water.

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

In addition, if the paper feed switch 52 is accidentally turned on while the user is seated, the memory 56 is configured to prevent the drive command from being sent to the electric motor 20 while the seating detection means 53 is detecting the seating.
Since the program is set to 1, it is possible to avoid an accident in which the next sheet of paper P is suddenly fed out while the user is seated, causing a paper jam in the paper delivery path 32.

Furthermore, when the sheet paper P is fed out, the paper clamping member 35° 35a on the upper surface of the installation space a of the inclined ceiling wall 17a is closed by a paper guide plate 44, and the mechanism of the suspension support frame 30 is closed. A paper jam prevention plate 45 is attached to the lower surface of the frame 29, except for the part where the protrusion 36a of the swing plate 36 passes through, so that the paper feed path 3
The sheet paper P fed out in step 2 is smoothly guided by the paper guide 44 plate and the paper jam prevention plate 45, and can be fed out without causing a paper jam.

Furthermore, if a paper jam occurs in the paper delivery path 32 while the sheet paper P is being fed out, in this embodiment, the time required to feed out the sheet paper P is set by the timer 57. If the paper position detection sensor 51 does not detect the through hole 50 of the sheet paper P even after the paper position has passed, it is determined that there is a paper jam or there is no paper, and the first
The paper trouble lamp 64 shown in the figure is turned on to notify the user that a paper jam or the like has occurred.

〔Effect of the invention〕

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

(1) The present invention is configured to cut the perforations of the sheet paper dispensed onto the toilet seat body in a fixed amount using the user's weight when sitting on the toilet seat body without using a cutting cutter. Therefore, sheet paper can be cut more quickly and reliably by using the perforations than the conventional cutting force lid.

(2) In addition, the mechanism for breaking the perforations of the sheet paper uses an operating lever to move the toilet seat itself up and down, which is lowered by the weight of the user, instead of the conventional electrically driven cutting cutter. Since a mechanism for cutting sheet paper is adopted with a simple structure in which rotational motion is converted to drive a sliding member, the sheet paper cutting mechanism can be manufactured simply and economically. .

(3) Furthermore, the sheet paper cutting mechanism takes advantage of the weight effect when the user sits on the toilet seat body and the weight effect when the user leaves the seat, so that the paper paper cutting mechanism appears in the paper delivery path. Because of this structure, when the sheet paper is fed out, there is no member such as a cutting cutter or the like that obstructs the feeding of the sheet paper in the paper feeding path as in the conventional case, so paper jams etc. do not occur. Smooth and smooth
Sheet paper can be fed out well.

(4) Furthermore, since the present invention adopts 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 power source for driving the electric motor, and this type of toilet seat can be used without any power supply equipment. It can be easily attached to Western-style toilets installed in poorly equipped public restrooms, etc., and the sheet paper automatic supply toilet seat itself can be made compact due to the simplification of its configuration, which has the advantage of reducing the manufacturing cost of the toilet seat.
