The main body 3 is provided with a plurality of guide rollers 71 for guiding the toilet paper P.

Reference numeral 73 denotes a toilet paper feeding device, and the feeding device 73 is provided with an unillustrated toilet paper roll. The toilet paper P drawn from the raw fabric is guided by the guide roller 75 of the feeding device 73 in a state where two sheets are stacked as a set, guided by the guide roller 71 of the toilet paper binding device 1, The vehicle travels so as to be fed between the knurling wheel 23 of the knurling unit 11 and the receiving roll 47. In the above operation, the receiving roll 47 is rotationally driven in the clockwise direction in FIG. 4, and the knurling wheel 23 is rotated in the counterclockwise direction following this.
Further, the toilet paper P is guided by the guide roller 71 and wound by a winding device (not shown). Then, the toilet paper roll R shown in FIG.

Next, the operation of the toilet paper binding apparatus 1 will be described.
When the toilet paper P travels between the knurling wheel 23 and the receiving roll 47, the toilet paper P is bound by the tooth portion 29 as shown in FIG. That is, two temporary fixing tooth portions 29b constituting one unit of action first bite into the two toilet papers P that are overlaid, and then one binding tooth portion 29a bites into the outer toilet paper P1 and breaks into a hole. Open H and bite into the inner toilet paper P2 while winding the broken portion of the outer toilet paper P1. In this way, a part of the toilet paper P1 bites into the toilet paper P2, and the two toilet papers P1 and P2 that are overlaid are bound so as not to be peeled off, and a hole H is formed in the bound portion. become.
This operation is continuously performed to form a large number of holes H arranged in the running direction of the toilet paper P, and the toilet papers P1 and P2 are continuously bound. As described above, since the distance between the two knurling wheels 23 is set to be smaller than the width N of the toilet paper roll R shown in FIG. 8, many holes H are arranged at both ends in the width direction of the toilet paper roll R. The toilet papers P1 and P2 are continuously bound.

  As described above, since the two toilet papers P on which the two temporary fixing tooth portions 29b are overlapped are bitten, the outer toilet paper P1 and the inner toilet paper P2 are temporarily fixed. The binding teeth 29a bite into the papers P1 and P2 to perform binding. Therefore, the outer toilet paper P1 and the inner toilet paper P2 are bound together in a state of being completely overlapped without shifting. Since the virtual line K connecting the center of the top of the two temporary fastening teeth 29b and the center of the top of the binding tooth 29a as described above is arranged to form an isosceles triangle, The portion that the binding tooth portion 29a bites into is held by a force that the stopping tooth portion 29b does not shift in any of the width directions of the toilet paper P. Therefore, it is possible to completely prevent the toilet papers P1 and P2 from shifting when the binding tooth portion 29a bites into the toilet paper P.

  In the above-described operation of attaching the toilet paper roll P, the knurling wheel 23 is supported by the swing holder 19 so as to be able to move close to and away from the receiving roll 47. Therefore, the air cylinder 39 passes the toilet paper P at a constant pressure. To elastically contact the receiving roll 47. Therefore, the substantially uniform hole H can be formed with respect to the toilet paper P, and the toilet paper P1 and the toilet paper P2 can be reliably bound in any part.

  Further, in the binding operation of the toilet paper roll P described above, air is intermittently blown from the air blowing pipe 36 to the tooth portion 29, and the paper powder of the toilet paper P attached to the tooth portion 29 is blown off and removed. The blown paper dust is sucked from the suction pan 40. Further, the tooth portion 29 is brought into sliding contact with the cleaning pad 30 impregnated with the cleaning liquid to remove paper dust. Therefore, it is possible to completely prevent the tooth portion 29 from being clogged with paper dust, and the tooth portion 29 can surely bite into the toilet paper P, so that the uniform binding of the toilet paper P can always be performed stably.

  When the toilet paper P that travels is cut off in the middle and the toilet paper P is wound around the receiving roll 47, a sensor (not shown) detects this. Then, by lowering the air pressure of the air cylinder 39, the swinging holder 19 is rotated counterclockwise in FIG. 4, so that the knurling wheel 23 is separated from the receiving roll 47, and the rotation of the receiving roll 47 is stopped. To do. This prevents the tooth portion 29 of the knurling wheel 23 from coming into direct contact with the receiving roll 47 and breaks it, and prevents the toilet paper P from being unnecessarily fed out.

If the tooth portion 29 of the knurling wheel 23 is in contact with the same portion of the peripheral surface of the receiving roll 47, the portion will be worn out. To prevent this, the operation of moving the knurling wheel 23 in the axial direction will be described. .
First, the holding bolt 31 is rotated by holding the knob 33 to release the pressure contact of the front end surface of the fixing bolt 31 against the mounting base 7, so that the unit base 13 is slidable along the support rail 9. Then, the unit base 13 is slid, the knurling wheel 23 is moved in the axial direction of the receiving roll 47, and the position where the tooth portion 29 contacts the receiving roll 47 is changed. Next, the knob 33 is held and turned to advance the fixing bolt 31, the tip end surface of the fixing bolt 31 is brought into pressure contact with the mounting base 7, and the unit base 13 is fixed to the mounting base 7.

The embodiment of the present invention has been described in detail above. However, the specific configuration is not limited to this embodiment, and the present invention can be changed even if there is a design change without departing from the gist of the present invention. included.
For example, in the embodiment described above, two toilet papers are stacked and bound, but the present invention is not limited to this and may be three or more.
The knurling wheel 23 is provided in one knurling unit 11 as a set, but one knurling wheel 11 may be provided in one knurling unit 11 or three or more.
The tooth portion 29 of the knurling wheel 23 is not limited to the shape shown in the above embodiment, and may have another shape such as a conical shape. Moreover, it is not limited to the aspect which makes the two temporary fixing tooth parts 29b and the one binding tooth part 29a one action unit, It is possible to select suitably.
