[Detailed Description of the Invention] [Industrial field of application] The present invention relates to the curl of a sheet paper roll wound around a core or the sheet paper which is reversely curled by a pressing roller, and can be caught or bent in its delivery path. The present invention relates to a sheet jam prevention device for a sheet paper, which is configured to prevent the occurrence of paper jam inside the device due to being jammed.

[Conventional technology]

In recent years, many Western style toilets have come to be used in hotels, restaurants, homes and the like. Since this Western-style toilet is used by sitting on a toilet seat that is attached to the toilet so that it can be raised and lowered, it is desirable that the toilet seat is always hygienic. In particular, in the case of Western style toilets installed in public facilities, etc., an unspecified large number of people share the toilet seats to make up for them, which is not desirable for public health, and they are installed in public places today. The social demand for hygienic use of existing Western style toilets is increasing day by day.

In view of the above points, recently, as an apparatus for automatically laying a sheet paper on a toilet seat, for example, the actual open sho-60-
The toilet seat cover supply device described in Japanese Patent No. 155399 can be found.

In the device, the upper surface of the toilet seat is shaped and sized so as to completely cover the upper surface of the toilet seat, and the continuous sheet paper is wound into a roll and accommodated in a protective cover. A paper holder that supports the sheet paper roll wound into a roll so that the sheet paper roll can be continuously fed out, and a feeding roller device for quantitatively feeding the sheet paper fed from the sheet paper roll onto a toilet seat, It is composed of a cutting device equipped with a cutting blade for separating the rear end side of the sheet paper, which has been fed quantitatively on the toilet seat, from the sheet paper roll, and the feeding operation is to turn on the paper feeding switch to feed the sheet paper. The sheet paper was cut by raising and lowering the cutting blade after the fixed amount was fed onto the toilet seat by the feed roller device. In this way, when using a Western-style toilet, it is possible to automatically lay a sheet of paper on the toilet seat and sit down, which is very hygienic.

[Problems to be solved by the device]

However, when the number of windings of the sheet paper roll becomes small, the sheet paper has a curl tendency toward the paper holder side, and when the sheet paper is unwound from the sheet paper roll in such a state, Since the curling habit remains at the feeding end, there is a risk that the feeding end may be caught or bent on the delivery path and cause paper jam. Further, a paper jam may occur due to a curling habit caused by wrapping around the feed roller device.

That is, in the toilet seat cover supply device, as described above, when the sheet paper has a winding habit due to the winding core on the delivery end side or a winding habit due to winding around the feed roller device, the delivery end side is curled. It cannot be passed through between the cutting blade composed of the upper blade and the lower blade, is blocked by the cutting blade, and is sequentially fed out from the feed roller device in the space between the feeding roller device and the cutting blade. There is a risk that paper jam may occur due to entanglement with the sheet paper or winding around the delivery roller device.

As described above, when the amount of sheet paper roll fed out is small, the sheet paper cannot be smoothly fed out due to the curl, and when paper jam occurs, it takes time to remove the sheet paper and the sheet paper is considerably wasted. In addition to being uneconomical, the sheet paper is not drawn onto the toilet seat, which may cause discomfort to the user.

In view of the above problems, the present invention attaches a guide member for preventing a paper jam on a delivery path when feeding a sheet paper,
It is an object of the present invention to provide a sheet paper jam prevention device for an automatic sheet-paper-feeding toilet seat in which the guide member is used to smoothly and favorably feed the sheet paper without specially correcting the curl.

[Means for Solving the Problems]

In the present invention, a sheet roller rewound from the sheet paper roll is sandwiched by a delivery roller in a casing on which a sheet paper roll is rotatably mounted, and a pressing roller that delivers the sheet paper from a paper delivery port onto a toilet seat. Between the pressing roller and the paper feeding port, a breaking protrusion is provided on the pressing roller side and a paper pressing portion is provided on the paper feeding port side, and a plurality of divided portions are provided with a certain interval on the pivot axis. A flat movable plate capable of holding the sheet paper between the inserted rotating plate and a paper pressing portion provided on the rotating plate by supporting the sheet paper under the rotating plate. And
A guide member formed by pivotally supporting the base end on the breaking protrusion side and extending the free end of the tip to the paper pressing side is formed in the space adjacent to each of the rotating plates so as to face the movable plate. It is characterized in that the sheet jam preventing device for the sheet paper is configured by rotatably arranging the sheet paper.

[Action]

According to the present invention, when the sheet paper is unwound from the sheet paper roll, the sheet paper is wound around the pressing roller in the direction opposite to the curl, and is nipped between the unrolling roller and unwound to roll out the sheet paper core. The curl which is caused by winding the pressure roller on the rotating plate is
By the guide member provided between the movable plate and the movable plate, it is possible to avoid entanglement with the rotating plate, eliminate the adverse effects of paper jam, and smoothly and satisfactorily feed the sheet paper. The feature is that even the last sheet of paper can be used.

However, as shown in FIG. Since the pressing roller 19 is attached so that the sheet paper f can be wound on the side opposite to the curl direction for about half a turn or more and can be nipped and fed between the feeding roller 15b and the feeding roller 15b, the sheet paper f has a curl tendency when it is fed. It can be delivered in a state in which it is almost eliminated. Also, sheet paper roll 11
When the remaining amount of the sheet paper becomes small, the curl of the sheet paper f becomes more severe, and even if the sheet paper f is wound around the pressure roller 19 in the opposite direction, it cannot be completely solved. In this case, as shown in FIG. Before the delivery, the curl may occur on the rotating plate 12 side in a state where the delivery end is in contact with the movable plate 20. When the sheet paper f is fed in such a state, the curled portion at the feeding end is rotated by the rotating plate 1.
The paper may get jammed by entering the space g in No. 2 above. However, according to the present invention, the space g is blocked by the first and second guide pieces 13c and 13d attached to the rotating plate 12 from the side of the breaking projection 14 to the connecting plate 8, and the seat is prevented from entering. The paper f is received in a state where the curl portion near the feeding end is prevented from being enlarged by the guide pieces 13c and 13d, and the paper delivery path 2 is directly received.
The inside of 1 can be moved without being held or bent while being guided by the guide pieces 13c and 13d, and can be smoothly delivered from the paper delivery port 18 onto the toilet seat 3.

Contrary to the above, when the sheet paper automatic feed toilet seat 1 is not used for a while, the sheet paper f is wound around the pressing roller 19 as shown in FIG. Even when the feeding end is in contact with the movable plate 20 as shown in FIG. 4, when the feeding is started, the portion of the sheet paper f wound around the pressing roller 19 may be curled clockwise. As a result, as shown in FIG. 12, the feeding roller 19 of the sheet paper f which is in contact with the movable plate 20 has the feeding roller 19 at the feeding end side.
The turning plate 1 is reversed by the curl portion generated by
Although it jumps up to the 2 side, the first and second guide pieces 13
The curls are prevented from being enlarged by being received by c and 13d. In this state, the sheet paper f is guided by the first and second guide pieces 13c and 13d and caught in the paper delivery path 21 without being wound around the rotating plate 12 or entwined with each other. , It can be moved without being bent and the paper delivery port 18
Can be pulled out onto the toilet seat 3.

At 3g, the guide pieces 13c and 13d are always held so as to be flush with the paper pressing portion c of the rotating plate 12, so that when the sheet paper f is fed out, the feeding end thereof is the rotating plate 12. There is no such thing as a paper jam caused by contact with. As described above, the sheet paper f is the toilet seat 3
When the sheet feeding position detecting sensor 28 detects the through hole 29 of the sheet paper f, the control device S sends a stop signal to the electric motor 16 to stop it. As a result, the sheet paper f is fixedly fed onto the toilet seat 3, and the perforations 30 are located between the feeding roller 15b and the breaking projection 14.
When the electric motor 16 stops, the control device S again causes the electric motor 2 to
5, a start signal is sent to the sheet 5, and the movable plate 20 is again rotated by the disc cam 24 toward the counterclockwise direction in FIG. When the paper f is lifted to the rotating plate 12 side and the movable plate 20 comes into contact with the rotating plate 12 and rotates it in the clockwise direction in FIG.
The sheet paper f is sandwiched between the plates 12 and 20, and the breaking projections 14 lightly contact the sheet paper f. In this state, the movable plate 20 is further rotated by the disk cam 24, and when the disk cam 24 is rotated about a half turn from the start, the movable plate 20 is moved from the inclined state of FIG. 5 to the state shown in FIG. Incline to the maximum angle. In the meantime, the rotating plate 12 is also pushed by the movable plate 20 and further rotates clockwise, and as shown in FIG. Press in the direction of rotation. As described above, due to the rotation of the movable plate 20, a large tension is applied to the sheet paper f between the movable plate 20 and the feeding roller 15b, and at the same time, the movable plate 20 is pushed and rotated to rotate. Since the breaking projection 14 of 12 strongly presses the contact point with the sheet paper f, the perforation 30 near the breaking projection 14 tears the sheet paper f at the same time as shown in FIG.
The sheet paper f corresponding to one sheet laid on the top is broken.

When the sheet paper f is broken as described above, the electric motor 25 is stopped by a command from the control device S, and the sheet paper f rotates, as shown in FIG.
As shown in FIG. 1, it is sandwiched between 2, 20 and on the toilet seat 3.
It can be laid without any bias. The user
In this state, sit on the toilet seat 3 via the sheet paper f,
The punching piece 31 is hung in the toilet bowl 2 for additional work.

When the user leaves the toilet seat 3 after the addition, a starting command is sent from the control device S to the electric motor 25 by the seating detection means (not shown), the disc cam 24 is rotated clockwise, and the movable plate 20 is moved to the first position. Rotate in the clockwise direction (direction returning to the original position) from the state shown in FIG. At this time, the rotating plate 12 returns to its original position by the force of the spring d, because the pressing by the movable plate 20 is gradually released.

When the user leaves the toilet seat 3 as described above,
The sheet paper f is a plate 12 which is still rotatable and movable,
Since it is sandwiched between 20, it does not cling to the buttocks. After this, flush water is poured into the toilet bowl 2 to
The sheet paper f on the toilet seat 3 is dragged into the inside of the toilet 2 via the punching piece 31 submerged in the water, and is discharged together with the dirty water. When the movable plate 20 returns to the original position, the paper feeding port 18 is closed in the same manner as before feeding the sheet paper f to prevent infiltration of dirty water. When the next user feeds the sheet paper f, the same as above. You can perform the operation.

Further, although the guide member 13 has been described with respect to the example in which the free end side is pivotally supported on the rotary play 12 toward the connecting plate 8 of the swing frame body 9, the present invention is not limited to this, and the free end side is provided on the breaking projection 14 side. Even if the connecting plate 8 is pivotally supported toward, the present invention can be realized.

[Effect of device]

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

(1) When the sheet paper is fed out, the curl generated in the taper itself is received by the guide member attached to the rotating plate or the connecting plate, and the curl portion of the sheet paper due to the curl is enlarged. Since the sheet paper is configured to be suppressed, the feeding of the sheet paper can be smoothly and favorably performed without causing a paper jam.

(2) Further, when the guide member is mounted on the rotating plate side, the space formed between the paper pressing portion and the breaking protrusion of the rotating plate can be effectively used for mounting. There is the advantage that no special space is required to mount this guide member.

As described above, according to the present invention, by providing the guide member on the lower side of the rotating plate so as to face the movable plate, it is possible to prevent the curled portion of the sheet paper from being enlarged and to smoothly feed the sheet paper. It has a practically excellent effect.
