Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a sheet paper feeding device that can take out sheet paper one by one from a feeding device provided on a wall surface and lay the sheet paper on a toilet seat of a Western style toilet.

[Conventional technology]

Generally, when trying to sit on a toilet seat when using a Western-style toilet, the skin is in direct contact with the toilet seat, and therefore, Japanese people with a strong sense of cleanliness have a strong sense of resistance. In particular, in public toilets such as hotels and department stores, people do not feel like sitting on a toilet seat who does not know who used it. Was. In this case, it takes time and effort to lay the toilet paper on the toilet seat, and the toilet paper is used for purposes other than its intended purpose, which is not only very uneconomical, but also involves dropping a large amount of toilet paper into the toilet at once. Since it was flushed, there was a risk that the drainage system of the toilet would be clogged.

[Problems to be solved by the invention]

For this reason, hospitals, hotels, restaurants, and other toilets that are used by an unspecified number of people recently have a size that covers the entire toilet seat.
In addition, a flush-disposable large-size sheet paper having a cutout formed at a position corresponding to the opening of the toilet seat is provided near the toilet, and the user spreads the sheet paper on the toilet seat and uses the sheet paper. Was. In this case, the sheet paper is often stored in a container in a state where a required number of sheets are folded, and in use, it is necessary to take out one sheet at a time from the container and spread it on the surface of the toilet seat. There was a trouble in using. Also, since the sheet paper itself is large, when storing it in a container, it must be folded and stored one by one in consideration of the storage space and ease of removal, and the work is extremely labor-intensive and troublesome. There was and was uneconomical.

In view of the above problems, recently, as an apparatus for automatically laying sheet paper on a toilet seat, for example, Japanese Utility Model Laid-Open No. 60-15539
No. 9 discloses a toilet seat cover supply device. This device winds a sheet of paper that is shaped and shaped so that it can completely cover the upper surface of the toilet seat and is continuous in a sheet form, stores it in a protective cover, and winds it in the roll form. A paper holder that supports the rolled sheet paper so that it can be continuously fed out, a feed roller device for feeding a continuous amount of sheet paper on the toilet seat, and a sheet paper fed for a fixed length on the toilet seat. The feeding operation is performed by feeding a paper feeding switch to feed a fixed amount of sheet paper onto a toilet seat using a feed roller device, and then raising and lowering the cutting blade to cut the sheet paper. Had gone. This device is convenient because the sheet paper can be automatically laid on the toilet seat by a switch operation.

However, the toilet seat cover supply device is provided with a blower device for ejecting air onto the toilet seat, and at the time of feeding out the sheet paper, the air is blown out onto the toilet seat by a pipe so that the sheet paper floats on the toilet seat. If the splashing water such as washing water that flows out together with the wastewater in the toilet or hand washing on the toilet seat surface remains as water droplets, the water droplets permeate the sheet paper being fed and adhere to the toilet seat. This prevents the paper sheet from continuing to be fed out and causing a paper jam even though it is no longer possible to slide on the toilet seat.

However, in order to eject air onto the toilet seat when the sheet paper is fed out, a special blower device is required, and piping between the blower device and the lower surface of the toilet seat is also required. Such as having to pierce the spout
There is a problem in terms of cost due to the large size of the sheet paper floating means, and if the jetting power of the air and the feeding speed cannot be balanced with each other, the sheet paper itself is large and thin. Therefore, smooth feeding was not performed, and there was a risk of causing paper jam.

In view of the above-mentioned problem, the present invention automatically feeds out sheet paper, and lays out the fed sheet paper on a toilet seat and sits down on the toilet, thereby sanitizing a Western toilet used by an unspecified number of people. It is an object of the present invention to provide an apparatus for feeding sheet paper for toilet seats that can be used in general.

[Means for solving the problem]

The present invention, in the main body, a paper feeding mechanism for feeding the sheet paper from the sheet paper roll to the outside through the paper delivery path, and cut the rear end of the fed sheet paper, and clamp the cut end side, And a paper feeding mechanism configured to include a paper cutting mechanism configured to close and openably open a paper feeding opening of the main body, and a control device that controls operations of both the paper feeding and cutting mechanisms. The paper feeding device installed in the mounting hole is provided so as to be able to be taken out of the mounting hole provided in the wall of the wall, and is not swingable. The opening / closing door of the feeding device is attached to the opening / closing door with a gap large enough to feed the paper. The power feeding / cutting means and the paper feeding mechanism for turning on and off the paper feeder and the paper feeding mechanism are held and fixed at a fixed position, and the paper feeding mechanism for opening and closing can be linked with the fixed position holding / release means. And

In response to a command from the control device 55, the energizing circuit of the electric motor 30 is closed to start the electric motor 30. As a result, the semi-circular cam 29 rotates, and the arc-shaped portion moves the movable plate 23 from the state shown in FIG. 2, that is, from the state in which the paper outlet 20 is closed, as shown in FIG. When the movable plate 23 reaches a position (see FIG. 7) in which the movable plate 23 reaches a position parallel to the paper delivery path 27 (see FIG. 7).
The motor 30 is temporarily stopped by a command from the control device 55, and instead, the motor 19 is started by a command from the control device 55. When the motor 19 is started, the feed roller 16 rotates, and the roller 16
The sheet paper P sandwiched between the pressing roller 15 and
While being sequentially rewound from the sheet paper roll R, the paper is fed from the movable plate 23 to the paper feeding port 20 via the spacer bar 59 while hanging down in parallel along the front surface of the mounting case 4 as shown in FIG. When the sheet paper P is fed out to a length covering the upper surface of the toilet seat 57, the paper feeding position detection sensor 53 detects the through hole 54 of the sheet paper P, and based on the detection signal, the control device 55 sends a stop signal to the electric motor 19. Send and stop this. Therefore, paper sheet P is fed out by a length to cover the toilet seat 57 and the perforation P ₁ is located between the feed roller 16 and the severance protrusion 24. When the motor 19 stops, the motor 30 is controlled by a command from the controller 55.
Is restarted, the movable plate 23 is rotated counterclockwise in FIG. 7 by the cam 29, and the sheet paper P lying on the paper delivery path 27 is lifted to the rotation plate 23 side. The movable plate 23 continues to rotate further with the sheet paper P lifted, and its rear end (rightward in FIG. 7) contacts the rotation plate 22 to move the sheet paper P between itself and the rotation plate 22. When the half-moon-shaped cam 29 rotates about half a circle from the start point (see FIG. 2) while being pinched, the movable plate 23 tilts substantially at the maximum angle as shown in FIG. Is rotated clockwise.
As a result, the sheet paper P is held by the pressing and feeding rollers 15,1.
At the same time that a large tension is applied between the clamping point 6 and the clamping point between the rotating and movable plates 22 and 23, the breaking projection 24 of the cutter base 25 attached to the rotating plate 22 is partially The sheet paper P is strongly pressed against the sheet paper P, so that a large tension is applied to the sheet paper P, and at the same time the perforation P ₁ near the breaking projection 24 is torn without resisting the pressing force of the breaking projection 24,
The remaining perforation P ₁ is broken to cut the paper sheet P. After the cutting of the sheet paper P, the electric motor 30 continues to rotate, and the cam 29 is rotated. For this reason, the driven roller 28 of the movable plate 23 comes into sliding contact with the vertical portion side from the arc portion of the cam 29.Therefore, the movable plate 23 does not rely on the cam action, but by the self-returning force of a spring member (not shown). 8 quickly returns to the original position side shown in FIG. 2 from the state inclined at the maximum angle, and closes the paper feeding port 20.
Therefore, when the movable plate 23 returns to the original position, the cut sheet paper P is instantaneously released from being pinched by the movable plate 23 and the rotating plate 22.
As shown in FIG. 2, the quick return of the sliding member 23 does not cause the sliding member 20 to slide out of the mounting housing 4 and fall out of the closing member 80 of the movable plate 23 and the lower surface of the connecting plate 13. Can be pinched by force. As described above, when the cutting of the sheet paper P is completed, the user operates the feeding port 20.
