In the sheet vapor supply snowmaking 10 configured as described above, when the switch 38 is pressed, the motor 64 rotates in the forward direction, and the drive shaft 5 is rotated through the gears 66, 68 and the one-way clutch 70
6 is rotated forward. In addition, at this time, the intermediate gear 152.154
Since the rotation in the reverse direction is transmitted to the drive shaft 72 via the one-way clutch 158, the one-way clutch 158 idles and the drive shaft 72 does not rotate. In this case, the cutting cams 74 to 84 and the clamping cams 86 to 90 are all in positions retracted to the inside of the opening 92.

As the drive shaft 56 rotates, the rubber roller 58 rotates,
After the sheet paper S unwound from the sheet paper roll body 22 has its running direction changed by the guide 71,
sandwiched between the rubber roller 58 and the driven rubber roller 60,
Sent to the front side.

Then, it is sent out onto the toilet seat 14 from the outlet 34.

When the sheet paper S is fed out onto the toilet seat 14 by a predetermined length, the opening 3 of the sheet paper S reaches the center 211-16.
It comes above 0. Then, the motor 64 is stopped by a signal from the sensor 160, and the feeding of the sheet paper S is stopped.

Following this motor stop, the motor 64 is reversed.

Then, the force in the normal rotation direction is transmitted to the drive shaft 72 via the intermediate gears 152 and 154, so that the drive shaft 72 rotates in the normal rotation direction. In addition, at this time, the drive shaft 56
Since a force in the reverse direction is applied to , the one-way clutch 70 idles and the drive shaft 56 stops.

As the drive shaft 72 rotates, the sheet paper S is held between the cam protrusions of the cutting cams 74 to 84 and the rubber rollers 94 to 104, respectively, as shown in FIG.
The sheet paper S is cut along perforation 1 as shown in FIG.

During this cutting, first the cams 74 on both ends of the drive shaft 72.
84 engages with the rubber rollers 94 and 104, cuts 4 are created on both ends of the sheet paper S in the width direction as shown in FIG. 16, and separation along the perforations 1 is started. After this cut 4 is generated, the cam protrusion of the cam 76.82 engages the rubber roller 96.102, applying tension to the inner part of the sheet paper S, and the cut 4 is moved toward the center of the sheet paper S. spread. Finally, the cam protrusion of the cam 78.80 engages with the rubber roller 98.100, applying tension to the widthwise central portion of the sheet paper S, and propagating the cut 4 to the central portion. Complete the disconnect.

As shown in FIG. 13, when the cutting cams 74-84 engage with the rubber rollers 94-104, the cams 74-84 push up the rubber rollers 94-104. Then, the driven shafts 106 to 110 are also pushed upward, and the U-shaped portions 112a to 116a are pushed upward. As a result, the brake plates 112b to 116b are pushed downward and brought into close contact with the rubber roller 60, so that the rubber roller 60 is braked. Therefore, the upstream side of the sheet paper S is firmly sandwiched between the rubber rollers 60 and 58. In this state, the downstream part of the sheet paper S is pinched by the cams 74 to 84 and the rubber rollers 94 to 104 and pulled forward by 1 length, thereby applying 1 tension to the sheet paper S and ensuring that it is aligned along the perforation 1. It can be cut into.

In this embodiment, in this cutting, first the cam 74.8
4 generates a cut 4 on both ends of the sheet paper S in the width direction, and since it is only necessary to apply tension to a part of the sheet paper S, a motor for generating this cut 4 is required. 64's small torque is sufficient.

In addition, after the first cut 4 occurs, the cams 76.82 pull the sheet paper S, and then the cams 78.80 apply tension to the sheet paper S, so the torque of the motor 64 when propagating the cut 4 is also small. That's enough. Therefore, according to this embodiment, the sheet paper S
A small motor 64 with low output is sufficient for cutting.

Note that after such cutting of the sheet paper S is completed, the drive shaft 72 continues to rotate further. All cams 74
~84 is separated from the rubber rollers 94~104, 'M
As shown in Fig. 14 and Fig. 15, the clamping cams 76 to 9
0 is in contact with the presser plate 142, and the clamping cam 86
The rear end of the separated single-use sheet paper 5 is sandwiched between the sheet paper 5 to 90 and the presser plate 142. This results in
The rear end of the sheet vapor 5 sent out onto the toilet seat 14 is clamped, and even if the toilet user seats his buttocks on the toilet seat 14, the sheet paper 5 is prevented from shifting back and forth and from side to side. It becomes like this.

In the above embodiment, the sheet paper S is moved to the rubber roller 58.
It runs in a direction almost perpendicular to the line segment connecting the axes of 60 (marked in FIG. 12). Therefore, even if the sheet paper S remains sandwiched between the rubber rollers 58 and 60 for a long time (the state shown in FIG. 14), the sheet paper S will not curl. Therefore, even if the switch 3B is pressed again and the sheet paper S is fed after a long period of stoppage (for example, at night or on a holiday at a factory, department store, etc.), the No paper jams or wrinkles occur.

In the above embodiment, the running direction of the sheet paper S intersects the line segment at an angle of approximately 90 degrees, but this angle is approximately a right angle (approximately 70' to 110 degrees, preferably 80 degrees to 1 degrees).
00°) is sufficient.

In the above embodiment, the sheet paper S fed into the rubber roller 58.60 in a direction orthogonal to the line segment is fed out from the rubber roller 58.60 in the same direction.
In the present invention, as shown in FIG. 17, the sheet paper S may be sent out in a direction different from the nipping direction. In the state shown in FIG. 17, if tension is left on the sheet paper for a long period of time, the sheet paper S will curl. On the downstream side in the direction, the sheet paper S is cut by the cutting mechanism 46, so that the leading edge f of the sheet paper S is cut as shown in FIG.
No tension is applied to f1lJ. Therefore, even if the running direction of the sheet paper S is changed downstream of the rubber rollers 58, 60, the sheet paper S is hardly curled.

[Effects] As described above, according to the sheet vapor supply device of the present invention, even if the sheet paper is held between the rollers of the delivery mechanism for a long time, the sheet paper does not curl, and the sheet vapor supply device does not curl. This prevents sheet paper from jamming and wrinkling.
