<Prior art> Roll sheet materials such as toilet paper are several thousand.
A paper having a length of m or more is made into a paper, and while perforated, the paper having a predetermined length (for example, 60 m) is wound around a core.

Further, when a paper of a predetermined length is wound around the core, the paper is once cut, and the roll sheet material on which the paper is wound is discharged to the outside of the system. The length of sheet material starts to be wound around the core.

A processing device capable of performing the above operation is usually
Consists of a winding device, a cutting device, and a discharging device. First, the winding device operates, and after winding 60 m of paper on the core,
At the same time as the winding device is at rest, the cutting device and subsequently the discharging device are activated. Then, after the paper is cut and the rolled roll sheet material is discharged to the outside of the processing system of the apparatus, the cutting apparatus and the discharging apparatus are stopped, and at the same time, the winding apparatus operates again.

The winding device in the above-described processing device is configured by connecting a drive source such as a motor and a winding roller via a clutch mechanism. When the clutch mechanism is turned on, paper is wound and the winding mechanism of the clutch mechanism is used. When it is off, winding is stopped.

Is possible.

<Problems to be Solved by the Invention> However, in the winding device as described above, in order to produce 6 or 7 roll sheet materials per minute, the on / off operation of the clutch mechanism is 12 to 12 minutes per minute. It will be repeated about 14 times, and the torque generated from these operations will cause a significant load on the motor, reduce the rotation accuracy of the drive source, and shorten the motor life. Therefore, replace the motor frequently. There is a need to. Further, it is difficult to operate the drive and the stop 12 to 14 times a minute with high accuracy and surely.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and the first rotating shaft rotated by the motor and the first rotating shaft having the clutch mechanism in the middle are the first Connected by rotation transmission material,
The second rotation shaft that rotates when the first rotation shaft rotates and the second rotation shaft that is communicated with the winding mechanism of the winding device that is operated by the motor described above are connected by the second rotation transmission member, and And a third rotating shaft to which the rotation of the second rotating shaft is transmitted when the clutch mechanism is turned on.
A buffer roller connected to the cylinder is brought into contact with the rotation transmitting material, and the torque of the winding mechanism that is generated at the moment when the clutch mechanism is turned on is applied.
It is characterized in that the torque of the rotation transmitting member is buffered and absorbed by the cylinder via the buffering roller described above.

<Operation> According to the present invention, in the winding device, the torque of the winding mechanism is buffered and absorbed and transmitted to the motor, whereby the torque acting on the motor can be significantly reduced, and the life of the motor is extended. The maintenance of the winding device can be significantly facilitated.

<Embodiment> An embodiment of the present invention will be described below in detail with reference to the drawings.

In the winding device driving device according to the present invention, the driving motor 1 and the first rotating shaft 2 are connected via the first pulley 3, the rotation transmitting member 4, and the second pulley 5, and the first rotating shaft 2
Can be rotated at high speed by driving the motor 1.

The above-described second pulley 5, flywheel 6, and third pulley 7 are attached to the first rotary shaft 2 that rotates together with the motor 1 described above, and the endless first rotation transmission member 8 is attached to the third pulley 7.
One end is hung.

A buffer roller 9 is elastically contacted from above in the middle of the above-described first rotation transmitting member 8, and the other end is hooked on the fourth pulley 10.

The cushioning roller 9 elastically contacting the first rotation transmitting member 8 is a source of action in the driving device of the present invention.
It is connected to a cylinder 11 connected to a hydraulic or pneumatic drive source (not shown), and has a configuration capable of varying the contact pressure on the first rotation transmission member 8.

In addition, the fourth pulley 10 around which the first rotation transmission member 8 is stretched has a clutch mechanism 12 in the middle thereof and has a fifth pulley 1
3 is attached to the second rotating shaft 15 provided at the other end, and when the first rotating shaft 2 rotates, the second rotating shaft 14 also rotates by the first rotation transmitting member 8. The fifth pulley 13 rotates when the clutch mechanism 12 is on, but does not rotate when the clutch mechanism 12 is off.

Further, one end of the endless second rotation transmission member 15 is stretched over the fifth pulley 13 described above, and the sixth pulley 16 is stretched over the other end side of the second rotation transmission member 15.

The sixth pulley 16 is integrally attached to the third rotating shaft 18 having a drive source roller 17 in the middle thereof, and the drive source roller 17 has a winding mechanism (not shown) for winding paper. No) is contacted directly or indirectly.

The structures of the cushioning roller 9 and the cylinder 11, which are essential components of the present invention, are shown in detail in FIGS. 2 and 3.

As described above, the buffer roller 9 is stretched between the third pulley 7 integrally attached to the first rotating shaft 2 and the fourth pulley 10 integrally attached to the second rotating shaft 14. The tension is adjusted by elastically contacting the first rotation transmitting member 8.

The cushioning roller 9 is rotatably held at one end of a tilting rod 19 which is pivotally supported in the middle of its length and is rotatably supported.
The tip of 1'is pivotally attached to the other end of the tilting rod 19 described above.

When the cylinder 11 is expanded and contracted by the configuration of the rotation buffer mechanism described above, the tilting rod 19 tilts, and the pressure at which the buffering roller 9 pivotally attached to the tip of the tilting rod 19 contacts the first rotation transmitting member 8 changes. The tension of the first rotation transmitting member 8 can be adjusted.

In the drive device of the winding device configured as described above,
When the motor 1 is driven, the rotation transmitting material 4 rotates the first rotating shaft 2 and the first rotation transmitting material 8 rotates the second rotating shaft 14.

If the clutch mechanism 12 is in the on state, the fifth
Since the pulley 13 rotates and the third rotating shaft 18 rotates,
The winding mechanism operates by the rotation of the driving source roller 17 attached to the third rotating shaft 18, and the paper can be wound around the core.

However, if the clutch mechanism 12 is off, the fourth
Since the rotation of the pulley 10 is not transmitted to the fifth pulley, the rotation of the drive source roller 17 is stopped. In this idle state, the end of the paper wound on the core is cut by a cutting device (not shown), and the roll-shaped sheet material is discharged to the outside of the winding device by a discharging device (not shown). is there.

By changing the on / off state of the clutch mechanism 12 as described above, a roll-shaped sheet material formed by winding paper is produced.
While the drive source roller 17, the cutting device, and the discharging device repeatedly operate and stop by turning the clutch mechanism 12 on and off, the motor 1, the first rotating shaft 2, and the first rotation transmitting member 8 are the clutch mechanism 12. It rotates continuously regardless of the on / off state of.

Therefore, the on / off state change of the clutch mechanism 12 causes the motor 1 to receive a strong torque of the winding mechanism via the first rotation transmitting member 8, the first rotation shaft 2, and the rotation transmitting member 4. . Then, the above-mentioned torque acts on the first rotation transmitting material 8, but the torque acting on the motor 1 can be extremely reduced due to the buffer absorption by the cylinder 11 via the buffer roller 9, so that the torque of the motor 1 can be reduced. The burden can be significantly reduced.

<Effects of the Invention> As described above, according to the drive device of the winding device of the present invention, the torque acting on the motor is used even when the device is used for high-speed production of a large number of roll-shaped sheet materials per minute. Can be significantly reduced.

Therefore, the life of the motor can be maintained for a remarkably long time, and it is not necessary to replace the motor as frequently as in the conventional case, and the maintainability of the winding device can be improved.

Further, since the drive device of the present invention only uses the cylinder for absorbing and absorbing the torque, it does not require a large-scale device and can be directly applied to the conventional device. , Is extremely practical.
