Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a new device that automatically supplies sheet paper to cover the seat of a Western-style toilet seat, and its purpose is to unwind sheet paper from a roll of sheet paper. To provide an automatic sheet paper supplying toilet seat of a simple structure capable of smoothly and well cutting a sheet of sheet paper fed out onto the toilet seat and automatically supplying it onto the toilet seat.

[Conventional technology]

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

The cover supply device has a size and shape that can cover the top surface of the toilet seat, and winds up continuous sheet paper into a roll and stores it in the protective cover. , a paper holder that supports the sheet paper roll so that it can be continuously fed out; a feeding roller device that feeds out the sheet paper fed from the sheet paper roll forward by a predetermined length near the top surface of the toilet seat; and a cutting device equipped with a cutting blade that cuts the rear end of the sheet paper fed out to a predetermined length onto the toilet seat.

In such a conventional cover feeding device, the sheet paper feeding and cutting operations are performed by turning on an operation switch, feeding out a fixed amount of sheet paper by a feeding roller device, and then moving the cutting blade up and down to cut the sheet paper. . In this way, when using a Western-style toilet, you can automatically spread sheet paper on the toilet seat and sit down.
The user can use the Western-style toilet seat hygienically, which is very convenient.

[YA problem to be solved by the invention]

However, in the toilet seat cover supply device having the above configuration,
There were the following problems.

(1) The sheet paper dispensed onto the toilet seat is soft and thin so that it can be disposed of by washing with water, and it is made in a large size to cover the top of the toilet seat, so it is very weak and has high absorbency. Therefore, it is extremely difficult to cut the sheet paper that has been unwound from the sheet paper roll and delivered onto the toilet seat. 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 has no holding means at all, so when cutting the sheet paper, the cutting point of the sheet paper is not connected to the movable blade. There were times when the blade could get 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. If the area near the cut end is curled due to the curl, it will not be placed on the fixed blade and will curl in the direction of the curl, and it will come into contact with the cutting blade during feeding. It was difficult to smoothly feed the sheet paper onto the toilet seat.

(3) Furthermore, the cutting blade for cutting the sheet paper is attached to the top of the sheet paper supply device and inside the sheet paper feed outlet, and sewage often splashes back and adheres to the sheet paper, resulting in unsanitary conditions. Not only that, but the cutting blade sometimes rusted due to the adhesion of sewage, making it impossible to cut the sheet paper. Moreover, the sheet paper that has been cut and fed out onto the toilet seat is not held in place by any pressing means, so that if you touch the sheet paper when you sit down, it may slide off the toilet seat, or when you leave the toilet seat, your buttocks may fall. There were problems such as unsanitary conditions due to people getting caught in the water.

In view of the above-mentioned problems, the present invention has been developed by dispensing a fixed amount of sheet paper onto a toilet seat, and then cutting the sheet paper in a straight line at a predetermined cutting position with the sheet paper being held in place by a heating means and maintaining the held state. However, the object of the present invention is to provide an automatic sheet paper supplying toilet seat which can be released from the clamp and automatically discharged into the toilet bowl after use.

[Means to solve the problem]

The present invention provides a feed roller for feeding out the sheet paper roll unwound from the sheet paper roll to a certain length onto the toilet seat main body, on the rear side of the center of the casing in which the sheet paper roll is horizontally suspended freely. A paper feeding means consisting of a pressure roller is provided, and a clamp plate that is raised and lowered by the rotation of a cam plate is located approximately in the center of the casing, and a sheet paper that is fed onto the toilet seat is located at an upper position opposite to this clamp plate. A clamp receiving body is installed horizontally at a position where it can come into contact with the clamp plate at an interval that allows the paper to pass smoothly through the clamp plate, and a heating portion is provided on the lower surface of the clamp receiving body in a direction perpendicular to the feeding direction of the sheet paper. A sheet paper clamping/cutting means consisting of a heater etc. installed in a straight line with the paper exposed downward is provided, and furthermore, the paper feeding means and the sheet paper clamping/cutting means are individually driven and controlled to separate the sheet paper. Since the automatic sheet paper supplying toilet seat is equipped with a control device that outputs commands for feeding, clamping, cutting, etc., its functions are as follows.

[Effect]

In the above configuration, the sheet paper unwound from the sheet paper roll is fed out to a certain length onto the toilet seat by the paper feeding means, and then the clamp plate of the sheet paper holding/cutting means is pushed up toward the clamp receiving body. The sheet paper is held in an almost airtight state, and then the heater installed in the clamp receiving body is energized for a short time.
Burn off the portion of the sheet paper that is in contact with the heater. That is, the toilet seat is cut, and after the cutting, the clamped state is maintained until the user finishes relieving himself, and when the user leaves the toilet seat,
The clamping state is automatically released, and the sheet paper on the toilet seat is removed by being discharged into the toilet bowl by the force of washing water flowing down into the toilet bowl when discharging waste.

A function of outputting a stop command to the electric motor 20 after rotating the cam plate 27 by half a rotation is programmed.

Next, the operation will be explained.

When feeding out the sheet paper P, when the paper feeding switch 35 is pressed, a human power signal from the switch 35 is inputted to the input terminal (2) of the microcomputer 45. Therefore, the drive command for the electric motor 18, which is programmed in advance in the memory k of the microcomputer 45, is transmitted by the microprocessor i to the drive circuit m from the output terminal ○ of the microcomputer 45.
, the photodiode D of the first phototriac PT emits light, and the phototriac p"r is turned on by conducting the triac T h + . As a result, the motor is powered on from the commercial power supply 47 for one day. The paper feeding means 7 is driven by the activation of the electric motor 18. That is, the feeding roller 16 is rotated,
The sheet paper P held between the pressing roller 9 in sliding contact with the sheet paper P is unwound from the sheet paper roll R and is fed onto the toilet seat main body 3 via the paper feed path 30 → paper feed outlet 29. As described above, the sheet paper P rewound from the sheet paper roll R is fed out to a length that covers the toilet seat main body 3, and when the paper feeding position detection sensor 31 detects the through hole 32 indicating the boundary of the -th sheet. , the detection signal is input to the microcomputer 45. Therefore, the microprocessor 1 outputs the stop command for the electric motor 18 programmed in the memory k from the output terminal 0 of the microcomputer 45 and outputs it to the first phototriac PT.
The photodiode D stops emitting light, and the trifuc Th
, becomes non-conductive. That is, the phototriac PT is turned off. Therefore, the J electric power is cut off to the electric motor 18, the drive is stopped, and the feeding of the sheet paper P is stopped. When the feeding of the sheet paper P is completely completed, the drive command for the electric motor 20 programmed in the memory k by the timer function of the microcomputer 45 is outputted from the output end 02 of the microcomputer 45 to the drive circuit m. Phototriac P
Similarly to T, turn on the second phototriac PT. Therefore, the electric motor 20 is started and rotates the cam plate 27. As the cam plate 27 rotates, the clamp plate 9 whose lower end is in contact with the cam plate 27 protrudes into the paper delivery path 30, and when the cam plate 27 rotates approximately half a turn, the clamp body 24 of the clamp plate 19 , lift the sheet paper P located at this location and attach it to the connecting plate 12 as shown in FIG.
It comes into contact with a clamp receiving body 15 provided on the side. At this point, the microprocessor i outputs a command to stop the motor 820 programmed in the memory k of the microcomputer 45 from the output @0□ of the microcomputer 45, turns off the second phototriac PT, and turns off the motor 20. Stop the drive. Therefore, the clamp plate 19 maintains a state in which it is pushed up toward the clamp receiving body 15 by the cam action of the cam plate 27, as shown in FIG. and sandwich the sheet paper P.

At this time, since both the clamp receiver 15 and the clamp body 24 are made of heat-resistant synthetic resin with some degree of elasticity, the sheet paper P is
4 in a substantially airtight state. Therefore, it is possible to reliably bring the sheet paper P into close contact with the heater 14 which is exposed and attached to the lower surface of the clamp receiver I5. As mentioned above, sheet paper P
After the microcomputer 45 has a timer function, the microprocessor i outputs an energization command to the heater 14, which is programmed in the memory k, from the output terminal 03 of the microcomputer 45 to the drive circuit m. Triac PT, turn on one. Therefore, the heater 14 is heated by electricity supplied from the commercial power source 47, and the portion of the sheet paper P that is in close contact with the heater 14 is burned off with a black line drawn thereon. In this case, the heater 14 has a 4% fi
By using a material that is thin and has a slightly small resistance value, it is possible to obtain a temperature that burns out the sheet paper P in a short time (about 1 to 2 seconds). Further, since the portion of the sheet paper P that is in close contact with the heater 14 is held in a nearly airtight state by the clamp plate 19 and the clamp receiving body 15, the sheet paper P is cut almost in an oxygen-free state. As a result, the cut portion of the sheet paper P may spread fire due to the heating of the heater 14, and the heater 14 itself has little opportunity to come into contact with oxygen during heating, so it may deteriorate and be damaged even if instantaneous energization is repeated. Very rarely. The energization time of the heater 14 is set by the timer function of the microcomputer 45 so that it is energized for a short time, so when the energization time ends, the microcomputer 45 outputs a command to stop the energization, and the third phototriac PT, is turned off, and power supply to the heater 14 is stopped. Even after the sheet paper P is cut, the electric motor 20 is not driven by the program set in the microcomputer 45, so that the sheet paper P is held in the sandwiched state. Further, since the paper feed position detection sensor 31 continues to detect the through hole 32 of the sheet paper P, even if the paper feed switch 35 is pressed by mistake, the electric motor will not start for one day. For this reason, the paper delivery path 30
In this state, the user inserts the punched piece 40 of the sheet paper P into the toilet bowl 2, leaving a part of it uncut, as shown by the two-dot chain line in FIG. After hanging down inside, the toilet seat body 3 is seated via the sheet paper P and refilled.

When the user is seated, the seating detection sensor 41 is turned on, and the microcomputer 45 is programmed so that, for example, even if the paper feeding switch 35 is pressed again by mistake, no drive command is output to the electric motor 18. Therefore, even if the position of the through hole 32 of the sheet paper P deviates from the detection position of the sensor 31, the electric motor will not be driven for one day.

Further, since the electric heater 14 is not energized at all by the program of the microcomputer 45, there is no possibility that the sheet paper P will become unclipped or that the sheet paper P will be burnt.

When the user finishes urinating and leaves the toilet seat main body 3, the seating detection sensor 41 is turned off. Therefore, the drive command for the electric motor 20 programmed in the memory k of the microcomputer 45 is output by the microprocessor i from the output terminal 02 of the microcomputer 45 to the drive circuit m, thereby turning on the second phototriac PTz. As a result, the electric motor 20 is driven, the cam plate 27 is rotated half a turn from the state shown in FIG. 4, the clamp plate 19 is lowered as shown in FIG. 3, and the sheet paper P is released from being clamped. The electric motor 20 is programmed to stop when the cam plate 27 is turned half a turn, so
The sheet paper P is released, and the clamp body 24 of the clamp plate 19 descends to a position flush with the inclined ceiling wall 22 and stops.

As mentioned above, since the sheet paper P is released from its grip, when flushing water is flushed into the toilet bowl 2, the punched piece 40 submerged in the toilet bowl 2 is dragged inside the toilet bowl 2 by the force of the flushing water. The sheet paper P on the toilet seat main body 3 can be automatically pulled into the toilet bowl 2 and discharged together with sewage.

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

Next, when replacing the sheet paper roll R, or when a paper jam occurs in the paper delivery path 30, the locking member 38 is pressed against the side wall C1d of the casing 6 to prevent it from locking with the cover 28. After untying, remove the cover 28 from the casing 6, and then attach the suspension support frame 10 to the boss part f.
As shown in FIG. 6, the sheet paper P is released from the grip by pulling up the toilet seat body 3 toward the front and releasing the sliding contact between the pressing roller 9 and the feeding roller 16. In this state, remove the paper holder g of the sheet paper roll R suspended horizontally on the suspension support frame 10, fit the paper holder g of a new sheet paper roll R into the boss part r of the suspension support frame 10, and then Set roll R,
Sheet paper P rewound from sheet paper roll R
As shown in FIG.
By returning 0 to its original position, the replacement work is completed. When the suspension support frame 10 is returned to its original position, the sheet paper P
As shown in FIG. 6, the paper can be automatically held between the feeding rollers 16 and ready for the next feeding.

Furthermore, even if a paper jam occurs in the paper feed path 30, the paper feed path 3o can be opened by pulling up the hanging support frame 10 as described above, and the jammed sheet paper can be removed. It can be easily removed from the paper delivery path 30.

〔Effect of the invention〕

As explained above, in the present invention, on the rear side inside the casing, there is a feeding roller and a pressing roller for pinching the sheet paper rewound from the sheet paper roll and feeding it a certain length onto the toilet seat body. A paper feeding means consisting of a clamp plate, which is raised and lowered by the rotation of a cam plate, is provided approximately in the center of the casing, and a gap is provided that allows the sheet paper to pass through the clamp plate, which is opposed to the clamp plate. A clamp receiving body is arranged at a position where it can come into contact with the clamp plate, and a means for holding and cutting sheet paper is provided with a heater for cutting sheet paper attached to the lower surface of the clamp receiving body, and the toilet seat body is The structure is such that the sheet paper that is fed upward is cut under almost oxygen-free conditions using the heat source of the heater, so there is no need to use a cutting blade to cut the paper as in the past. By using this, it becomes possible to solve various problems that arise at once, and the sheet paper cutting operation in the automatic sheet paper supplying toilet seat can be performed smoothly and efficiently.

Also, when cutting the sheet paper, the cut point is brought into airtight contact with the clamp member and then cut by heating with a heater, so the cut point of the sheet paper is in the state shown by the black line of - This makes it possible to cut smoothly without causing any part of the fire to spread. Moreover, since the cut portion is held in an airtight state by the clamp member after cutting, there is no possibility that the sheet paper will spread fire due to residual heat from the heater. Moreover, by using a synthetic resin with excellent heat resistance and self-extinguishing properties for the clamp member, it is possible to reliably prevent a fire from occurring due to the use of the heater.

In addition, when the sheet paper is fed out, the sheet paper is structured so that it passes through the narrow space between the connecting plate of the hanging support frame and the sloping ceiling wall of the casing and is fed onto the toilet seat body. Even if the edge is curled, the curling state can be suppressed by passing through a narrow space and the paper can be held between the feeding rollers. This completely eliminates the possibility of clogging due to the presence of paper sheets, and the sheet paper can be fed out smoothly.
