  In Patent Literature 1, an upstream winding base and a downstream winding base that move in the horizontal direction, and a winding that is detachably attached to the upstream winding base and the downstream winding base and holds the winding shaft. A sheet winding apparatus including a take-up arm is disclosed. The upstream side winding base and the downstream side winding base are configured so that the mounted winding arm can be moved in the vertical direction, and the mounted winding arms can be transferred to each other.

  Further, below the upstream winding base and the downstream winding base, an upstream touch roller base and a downstream touch roller base to which a touch roller arm that holds the touch roller is detachably mounted are arranged. The upstream touch roller base is fixed, while the downstream touch roller base is configured to move in the horizontal direction. The upstream touch roller base and the downstream touch roller base are configured such that the attached touch roller arm can be moved in the vertical direction, and the attached touch roller arm can be transferred to each other.

  In this sheet winding device, when the sheet is wound, the sheet is wound around the winding shaft of the winding arm attached to the upstream winding base, and the lower surface of the sheet is used as the upstream touch roller base. It is pressed by the touch roller of the attached touch roller arm. That is, when the upper surface of the sheet supplied from the previous process (upstream side) is wound, it is arranged on the inner side, which is a so-called lower winding.

  Further, in this sheet winding device, when the winding shaft is switched, the winding arm on which the upstream winding base and the downstream winding base are mounted is transferred to the upstream winding roller and the downstream touch roller. The touch roller arms on which the bases are mounted are transferred to each other. And while the sheet pressed by the touch roller transferred to the downstream touch roller base is wound by the winding shaft transferred to the downstream winding base, the downstream touch roller base and the downstream winding base Moves in the horizontal direction (downstream). Thereafter, the touch roller transferred to the upstream side touch roller base rises and the winding shaft transferred to the upstream side winding base descends, so that the sheet is pressed against the winding shaft by the touch roller. In this state, the sheet is cut, and the sheet is taken up by the take-up shaft of the take-up arm transferred to the upstream take-up base.

  Thereby, in the sheet winding apparatus of Patent Document 1, it is possible to press the sheet against the winding shaft by the touch roller from the start of winding of the sheet until the end of winding.

Next, with reference to FIG. 1 to FIG. 11, an operation during lower winding of the sheet winding apparatus 100 according to the present embodiment will be described.

  When the sheet winding device 100 starts the lower winding of the sheet 150, as shown in FIG. 1, the upstream winding base 11 is disposed at the most upstream position, and the downstream winding base 12 and the downstream touch are placed.

At this time, the air shaft 1 is rotated counterclockwise in FIG. 1 in a state where the lower surface of the sheet 150 is pressed by the touch roller 2, and is disposed inside when the upper surface of the sheet 150 is wound up. The

  As shown in FIG. 2, the upstream winding base 11 moves downstream (Y1 direction) in accordance with an increase in the winding diameter caused by winding the sheet 150.

As a result, as shown in FIG. 3, the downstream winding base 12 is disposed adjacent to the winding arm 1 a mounted on the upstream winding base 11, and the winding mounted on the downstream winding base 12. An upstream winding base 11 is disposed adjacent to the arm 1a. Similarly, the downstream touch roller base 14 is disposed adjacent to the touch roller arm 2a mounted on the upstream touch roller base 13, and the upstream touch roller 2a is mounted on the touch roller arm 2a mounted on the downstream touch roller base 14.

Then, as shown in FIG. 11, after the conveying device 17 moves to the upstream side and the air shaft 1 whose core has been exchanged is attached to the winding arm 1 a of the downstream winding base 12, the conveying device 17 is Move downstream. Thereafter, the winding arm 1a attached to the downstream winding base 12 is raised, and the downstream winding base 12 waits until the next switching of the winding shaft.

Accordingly, as shown in FIG. 14, the downstream winding base 12 is disposed adjacent to the winding arm 1 a mounted on the upstream winding base 11, and the winding mounted on the downstream winding base 12. An upstream winding base 11 is disposed adjacent to the arm 1a. Similarly, the downstream touch roller base 16 is disposed adjacent to the touch roller arm 3a attached to the upstream touch roller base 15, and the upstream touch roller 3a is attached to the touch roller arm 3a attached to the downstream touch roller base 16. A base 15 is disposed adjacent to the base 15.

  As shown in FIG. 15, the winding arm 1a (upper winding arm 1a) mounted on the upstream winding base 11 is transferred to the downstream winding base 12, and the downstream winding base. The winding arm 1 a (the lower winding arm 1 a) attached to 12 is transferred to the upstream winding base 11. Similarly, the touch roller arm 3 a (lower touch roller arm 3 a) attached to the upstream touch roller base 15 is delivered to the downstream touch roller base 16 and attached to the downstream touch roller base 16. The touch roller arm 3a (upper touch roller arm 3a) is transferred to the upstream touch roller base 15.

  Then, as shown in FIG. 16, the sheet 150 pressed by the touch roller 3 transferred to the downstream touch roller base 16 is wound by the core of the air shaft 1 transferred to the downstream winding base 12. As a result, the downstream winding base 12 and the downstream touch roller base 16 move downstream. Further, the upstream winding base 11 moves upstream to the most upstream position.

  Thereafter, as shown in FIG. 17, the winding arm 1a mounted on the upstream winding base 11 is raised, and the touch roller arm 3a mounted on the upstream touch roller base 15 is lowered. As a result, the sheet 150 is pressed against the core of the air shaft 1 of the upstream winding base 11 by the touch roller 3 of the upstream touch roller base 15. That is, the winding core of the air shaft 1 of the upstream winding base 11 and the touch roller 3 of the upstream touch roller base 15 are moved to the winding position.

  Then, the sheet 150 is cut by a cutting device (not shown), and the sheet 150 is wound around the core of the air shaft 1 held by the winding arm 1 a mounted on the upstream winding base 11. That is, the winding core (winding shaft) of the air shaft 1 is switched. Thereafter, as shown in FIG. 18, the touch roller arm 3a attached to the downstream touch roller base 16 is raised, and the downstream touch roller base 16 waits until the next switching of the winding shaft. Further, the downstream winding base 12 moves downstream.

  Then, as shown in FIG. 19, the transport device 17 moves upstream. Thereafter, in a state where the air shaft 1 of the winding arm 1 a mounted on the downstream winding base 12 is supported by the transport device 17, the air shaft 1 is removed from the winding arm 1 a.

  Thereafter, as shown in FIG. 20, the transport device 17 that supports the air shaft 1 moves downstream. When the product cradle 6 is raised, the core (product) around which the sheet 150 is wound is inherited from the transport device 17 to the product cradle 6. Thereafter, the air shaft 1 is pulled out from the core by a shaft pulling device (not shown), and the product from which the air shaft 1 has been pulled out is released. And a new winding core is arrange | positioned at the product receiving stand 6, and the air shaft 1 is inserted in the winding core by a shaft insertion / extraction apparatus.

  Thereafter, as shown in FIG. 21, the air shaft 1 on which the winding core is mounted is delivered from the product receiving base 6 to the conveying device 17. Then, as shown in FIG. 22, after the conveying device 17 moves to the upstream side and the air shaft 1 whose core has been exchanged is attached to the winding arm 1 a of the downstream winding base 12, the conveying device 17 is Move downstream. Thereafter, the downstream winding base 12 stands by until the next switching of the winding shaft.

  By repeatedly performing the above operation, the sheet 150 is continuously wound up while switching the winding core (winding shaft) of the air shaft 1.

-Effect-
In this embodiment, as described above, the upstream touch roller base 13 and the downstream touch roller base 14 for lower winding, and the upstream touch roller base 15 and the downstream touch roller base 16 for upper winding are provided. Thus, the lower surface of the sheet 150 can be pressed by the touch roller 2 to perform the lower winding, and the upper surface of the sheet 150 can be pressed by the touch roller 3 to perform the upper winding. Therefore, lower winding or upper winding can be selected and performed. That is, both lower winding and upper winding can be performed non-simultaneously.

  Further, in the present embodiment, since the sheet 150 can be pressed against the core by the touch roller 2 or 3 after the winding of the sheet 150 is started until the winding is finished, The occurrence of loss or the like can be suppressed.

  In the present embodiment, when the winding core (winding shaft) of the air shaft 1 is switched, the downstream winding base 12 and the downstream touch roller base 14 or 16 move horizontally to the downstream side. Compared with a so-called turret type that turns when the shaft is switched, the posture of the seat 150 can be made constant, so that the winding quality can be improved.

  In the present embodiment, when the sheet 150 is wound, the upstream side winding base 11 moves downstream in accordance with the increase in the winding diameter caused by winding the sheet 150, so that the touch roller 2 or 3 The pressing force can be made constant.
