-Operation-
Next, with reference to FIGS. 1-7, operation | movement of the sheet winding apparatus 100 by this embodiment is demonstrated.

[When winding the sheet]
First, as shown in FIG. 1, the sheet 150 supplied from the previous process (upstream side) is conveyed between the winding shaft 11 and the touch roller 22 at the winding position P1. And the sheet | seat 150 is wound up by the core 11a of the winding shaft 11 by rotating the winding shaft 11 of the winding position P1 counterclockwise of FIG.

  At this time, the touch roller 22 is disposed above the winding shaft 11 at the winding position P1, and the touch roller 12b is disposed below the winding shaft 11 at the winding position P1. For this reason, the sheet 150 wound around the winding shaft 11 at the winding position P1 is pressed so as to be sandwiched between the touch rollers 22 and 12b. For this reason, even if the sheet 150 is a non-woven fabric, the sheet 150 can be tightly wound around the winding shaft 11.

  Here, the nip roller 23 is in contact with the touch roller 22 via the sheet 150, and the angle range in which the sheet 150 contacts the touch roller 22 is large. Then, the touch roller 22 is driven and rotated in accordance with the conveyance speed of the sheet 150, and the winding shaft 11 and the touch roller 12b at the winding position P1 are driven and rotated in an auxiliary manner.

  In addition, the sheet | seat support apparatus 3 and the cutting winding apparatus 4 are each arrange | positioned in the initial position. Further, in the touch roller mechanism 12 arranged on the downstream side (Y1 direction side) of the turret mechanism 1, the touch roller 12b is arranged on the upper side (Z1 direction side), and the touch roller 12b becomes a new winding at the retracted position P2. It is separated from the taking shaft 11.

  When the winding diameter increases due to the winding of the sheet 150, as shown in FIG. 2, the touch roller 22 is moved upward (Z1 direction) in accordance with the increase in the winding diameter, and the touch roller 12b is moved downward (Z2 direction).

[When winding axis is switched]
When the switching of the winding shaft 11 is started, first, the turret mechanism 1 is rotated 180 degrees in the R1 direction around the rotation shaft 1a. As a result, as shown in FIG. 3, the winding shaft 11 located at the winding position P1 is retracted to the retracted position P2, and the new winding shaft 11 positioned at the retracted position P2 is retracted to the winding position. Supplied to P1. In this way, when the winding shaft 11 at the winding position P1 moves to the retracted position P2, the touch roller 12b that presses the sheet 150 wound around the winding shaft 11 also moves. That is, the take-up shaft 11 is moved from the take-up position P1 to the retracted position P2 while the sheet 150 taken up by the touch roller 12b is pressed.

  Here, when the winding shaft 11 is switched, the sheet 150 is wound by the winding shaft 11 at the retracted position P2 until the sheet 150 is wound around the winding core 11a of the new winding shaft 11 at the winding position P1. It is done. That is, the winding shaft 11 is switched without stopping the conveyance of the sheet 150 supplied from the previous process (upstream side). The sheet 150 taken up by the take-up shaft 11 at the retracted position P2 is continuously pressed by the touch roller 12b.

  Further, the sheet 150 is brought into contact with the new winding shaft 11 at the winding position P1, and the sheet 150 from the new winding shaft 11 toward the winding shaft 11 at the retracted position P2 is guided by the guide rollers 13 and 14. As a result, a conveyance path for the sheet 150 avoiding the touch roller 12b disposed on the upstream side is formed.

  Note that the guide roller 14 with which the sheet 150 comes into contact is disposed below the new winding shaft 11 at the winding position P1 and further upstream than the upstream touch roller 12b. Further, the guide roller 13 in contact with the sheet 150 is disposed below the upstream touch roller 12b, and is disposed downstream of the guide roller 14 in contact with the sheet 150.

  Next, as shown in FIG. 4, in the sheet support device 3, the first arm (not shown) is rotated to move the second arm 31 downward, and in the cutting and winding device 4, When the arm 41 is rotated about the rotation shaft 41a, the guide rollers 44 and 45 are brought into contact with the sheet 150 between the new winding shaft 11 and the guide roller 14 at the winding position P1.

  Thereafter, as shown in FIG. 5, in the seat support device 3, the second arm 31 is rotated about the rotation shaft 31a, whereby the plate-like member 32 is moved to the new winding shaft 11 at the winding position P1. It is arranged in the vicinity of Further, in the cutting and winding device 4, the third arm (not shown) that supports the guide roller 45 is rotated so that the guide roller 45 is disposed in the vicinity of the plate-like member 32 and supports the pressing roller 46. When the fourth arm (not shown) is rotated, the pressing roller 46 is brought into contact with the new winding shaft 11 at the winding position P <b> 1 via the sheet 150.

  At this time, the touch roller 22 is disposed above the new winding shaft 11 at the winding position P 1, and the touch roller 22 is brought into contact with the new winding shaft 11 via the sheet 150. Further, a pressing roller 46 is disposed below the new winding shaft 11 at the winding position P 1, and the pressing roller 46 is brought into contact with the new winding shaft 11 via the sheet 150. Further, a charging device 47 is disposed in the vicinity of the upstream side (Y2 direction side) of the new winding shaft 11 at the winding position P1, and the sheet 150 wound around the new winding shaft 11 is charged by the charging device 47. .

  Further, the guide roller 45 is disposed in the vicinity of the downstream side of the new winding shaft 11 at the winding position P1. Note that the guide roller 45 is disposed at substantially the same height as the new winding shaft 11 at the winding position P1. For this reason, the sheet 150 is conveyed from the new winding shaft 11 at the winding position P1 toward the guide roller 45 obliquely upward toward the downstream side. That is, the guide roller 45 is provided in order to define the conveyance direction of the sheet 150 fed from the new winding shaft 11 at the winding position P1. In addition, the guide roller 44 is disposed below the guide roller 45 and is disposed downstream of the tip of the second arm 42. For this reason, the conveyance path | route of the sheet | seat 150 which avoided the blade 43 etc. is formed. The sheet 150 fed from the new winding shaft 11 at the winding position P1 is conveyed to the winding shaft 11 at the retracted position P2 via the guide rollers 45, 44, 14 and 13.

  The plate-like member 32 is disposed at a position facing the guide roller 45 with the sheet 150 interposed therebetween. The surface of the plate member 32 is disposed in the vicinity of the guide roller 45, and the sheet 150 conveyed is slightly separated from the surface of the plate member 32. Further, the plate-like member 32 is disposed in the vicinity of the new winding shaft 11 at the leading end at the winding position P1. That is, the tip of the plate-like member 32 is disposed in the vicinity of the cutting position of the sheet 150. The cutting position is between the new winding shaft 11 and the plate member 32 at the winding position P1 in the conveyance direction of the sheet 150.

  Next, as shown in FIG. 6, in the cutting and winding device 4, the second arm 42 is rotated around the rotation shaft 42a, whereby the new winding shaft 11 and the guide roller at the winding position P1. The blade 43 moves in a direction substantially perpendicular to the conveying direction of the sheet 150 between the blades 45 and 45. For this reason, when the blade 43 enters between the new winding shaft 11 at the winding position P <b> 1 and the plate-like member 32, the sheet 150 is cut by the blade 43. Here, when the sheet 150 is cut by the blade 43, the cut sheet 150 is pressed against the plate-like member 32, and the sheet 150 is supported by the plate-like member 32.

  Further, when the sheet 150 is cut, the air discharge portion 48 and the cutting end guide portion 49 together with the blade 43 are moved to the vicinity of the new winding shaft 11 at the winding position P1. The air discharge portion 48 is disposed upstream of the blade 43 in the flow direction of the sheet 150, and the cutting end guide portion 49 is disposed between the blade 43 and the air discharge portion 48. Then, air is discharged from the air discharge portion 48, and the upstream cut end of the sheet 150 is sprayed onto the new winding shaft 11 at the winding position P1. Further, the cutting end guide portion 49 is arranged along the outer periphery of the winding shaft 11 in a state of being slightly separated from the new winding shaft 11 at the winding position P1, and is discharged from the air discharge portion 48. Along with the air, the cut end of the sheet 150 is guided between the new winding shaft 11 and the cut end guide portion 49. Then, the cut sheet 150 is wound around the new winding shaft 11 at the winding position P1. Note that the cut end on the downstream side of the sheet 150 is wound around the winding shaft 11 at the retracted position P2.

  And as shown in FIG. 7, the sheet | seat support apparatus 3 and the cutting winding apparatus 4 return to an initial position. Thereafter, the touch roller 12b disposed on the upstream side is raised, and the winding shaft 11 at the winding position P1 is pressed by the touch roller 12b. Further, the roll 160 wound up at the retracted position P2 is discharged. Specifically, the winding shaft 11 at the retracted position P2 is removed from the turret mechanism 1, and the roll 160 is extracted from the winding shaft 11. Then, a new winding core 11a is fitted into the winding shaft 11, and the new winding shaft 11 is attached to the retracted position P2.

  By repeating the above operation, the sheet 150 is continuously wound while the winding shaft 11 is switched.

-Effect-
In the present embodiment, as described above, by providing the sheet support device 3 including the plate-like member 32, when the sheet 150 is cut by the blade 43, the sheet 150 can be supported by the plate-like member 32. Thus, the escape of the sheet 150 can be further suppressed. That is, since the length of the sheet 150 traveling in the air can be shortened between the new winding shaft 11 and the plate-like member 32 at the winding position P1, the cutting performance of the sheet 150 can be improved. . Therefore, even if the sheet 150 is a non-woven fabric and is difficult to cut, it can be cut appropriately.

  In the present embodiment, by providing the turret mechanism 1 with the touch roller mechanism 12, the sheet 150 to be wound can be pressed even when the winding shaft 11 is switched. Even if the sheet 150 is a non-woven fabric, the sheet 150 can be tightly wound around the winding shaft 11.
