The link mechanism 172 includes a first arm 1721, a shaft 1722, a second arm 1723, and a stay 172a. The first arm 1721, the shaft 1722, and the second arm 1723 are provided as a left and right pair, as shown in FIG. That is, the first arm 1721, the shaft 1722, and the second arm 1723 are provided to face each other in the width direction of the film 150.

One end 1721a of the first arm 1721 is rotatably provided to the first fixed frame 17a, and the second arm 1723 is rotatably connected to the other end 1721b.

The first fixed frame 17a is connected to the second fixed frame 17b via a stay 17c. The first fixed frame 17a, the second fixed frame 17b, and the stay 17c are provided as a left and right pair. The pair of first fixed frames 17a are connected by a shaft 172b, and the first arm 1721 is connected to the first fixed frame 17a via the shaft 172b. Note that the first fixed frame 17a and the second fixed frame 17b are provided immovably.

As shown in FIGS. 2 and 10, one end 1722a of the shaft 1722 is disposed directly below the one end 1721a of the first arm 1721, and the other end 1722b of the shaft 1722 is located directly below the other end 1721b of the first arm 1721. is located directly below. Further, the distance between one end 1721a of the first arm 1721 and one end 1722a of the shaft 1722 and the distance between the other end 1721b of the first arm 1721 and the other end 1722b of the shaft 1722 are are set to the same. Therefore, the shaft 1722 is arranged below the first arm 1721, and the first arm 1721 and the shaft 1722 are arranged in parallel.

The second arms 1723 are formed to extend in the vertical direction, and the pair of second arms 1723 are connected by a stay 172a. The stay 172a (see FIG. 3) is formed to extend in the width direction of the film 150 (the axial direction of the core 51), and is provided at the upper end of the second arm 1723. A cutting section 171, a charging section 174, and an air discharge section 175 are attached to the stay 172a.

The cylinder body 1712a is attached above the stay 172a. The slider 1712b is disposed above the cylinder body 1712a and is movable along the cylinder body 1712a. A cutting blade 1711 (see FIG. 2) is attached to the slider 1712b via a holder 1711a. As shown in FIG. 2, the holder 1711a is formed to extend upward from the slider 1712b, and a cutting blade 1711 is attached to the upper end of the holder 1711a.

The air discharge part 175 is attached to the stay 172a via a bracket 175a, and is disposed on the downstream side (Y1 direction side) with respect to the cutting blade 1711. For example, the air discharge section 175 has a pipe extending in the width direction of the film 150. A plurality of discharge holes through which air is discharged are formed in the pipe, and the plurality of discharge holes are arranged at intervals in the width direction of the film 150.

-motion-
Next, the operation of the film winding device 100 according to this embodiment will be described with reference to FIGS. 1 to 10.

Note that when the film 150 is wound by the film winding device 100, as shown in FIG. A roller base 15 is arranged on the downstream side (Y1 direction side). The winding arm 13 mounted on the upstream winding base 11 is arranged on the lower side, and the touch roller arm 16 mounted on the upstream touch roller base 14 is arranged on the upper side and mounted on the downstream winding base 12. The winding arm 13 is disposed on the upper side, and the touch roller arm 16 mounted on the downstream touch roller base 15 is disposed on the lower side. Furthermore, in the cutting mechanism 17 (see FIG. 2), the air cylinder 173 is reduced and the second arm 1723 is retracted downward.

First, a film 150 supplied from a film forming line (upstream side) is fitted into a winding core 51 by a plurality of rollers 18 onto a winding shaft 50 of a winding arm 13 mounted on an upstream winding base 11; It is conveyed between the touch roller 16a of the touch roller arm 16 mounted on the upstream touch roller base 14. Then, by rotating the winding core 51 with the touch roller 16a of the upstream touch roller base 14 pressing the film 150 against the winding core 51 of the upstream winding base 11, the film 150 is wound around the winding core 51. taken. Specifically, with the lower surface of the film 150 in contact with the touch roller 16a, the core 51 is rotated counterclockwise in FIG. It will be done. That is, lower winding is performed in the film winding device 100.

Then, as shown in FIG. 4, as the winding diameter of the winding roll 151 formed by winding the film 150 increases, the upstream winding base 11 is moved downstream (towards the Y1 direction).

Thereafter, when switching of the winding core 51 is started, first, as shown in FIG. 5, the downstream winding base 12 and the downstream touch roller base 15 are moved upstream (Y2 direction side). As a result, the winding arm 13 attached to the upstream winding base 11 is arranged adjacent to the downstream winding base 12, and the winding arm 13 attached to the downstream winding base 12 takes up the upstream winding. It is arranged adjacent to the base 11. Further, the touch roller arm 16 attached to the upstream touch roller base 14 is arranged adjacent to the downstream touch roller base 15, and the touch roller arm 16 attached to the downstream touch roller base 15 is arranged adjacent to the upstream touch roller base 15. It is located adjacent to 14.

Next, as shown in FIG. 6, the winding arm 13 (lower winding arm 13) attached to the upstream winding base 11 is transferred to the downstream winding base 12, and the downstream winding The winding arm 13 (upper winding arm 13) mounted on the winding base 12 is transferred to the upstream winding base 11. Additionally, the touch roller arm 16 (upper touch roller arm 16) mounted on the upstream touch roller base 14 is transferred to the downstream touch roller base 15, and the touch roller arm 16 (upper touch roller arm 16) mounted on the upstream touch roller base 14 is transferred to the downstream touch roller base 15. The roller arm 16 (lower touch roller arm 16) is transferred to the upstream touch roller base 14.

As shown in FIG. 7, while the film 150 pressed by the touch roller 16a delivered to the downstream touch roller base 15 is wound up by the core 51 delivered to the downstream winding base 12, The downstream take-up base 12 and the downstream touch roller base 15 are moved downstream. As a result, the winding core 51 and the touch roller 16a, which are winding the film 150, are retracted to the downstream side. Furthermore, the upstream winding base 11 is moved upstream.

Thereafter, as shown in FIG. 8, the winding arm 13 mounted on the upstream winding base 11 is lowered, and the touch roller arm 16 mounted on the upstream touch roller base 14 is raised. Therefore, the touch roller 16a of the upstream touch roller base 14 presses the film 150 against the new core 51 of the upstream winding base 11. At this time, the distance between the winding core 51 on the downstream side and the new winding core 51 on the upstream side (the length of the film 150 being conveyed floating in the air) is reduced, The film 150 is conveyed diagonally upward from the core 51 of the side winding base 11 toward the touch roller 16a of the downstream touch roller base 15. Note that the film 150 is wound around the new winding core 51 of the upstream winding base 11, and the film 150 is in contact with the winding core 51 within an angular range of about 135 degrees in the circumferential direction.

Then, as shown in FIG. 9, the cutting mechanism 17 is raised. Specifically, as shown in FIG. 10, when the air cylinder 173 is extended, the link mechanism 172 is swung, and the second arm 1723 is advanced upward. At this time, the cutting blade 1711 is disposed between the new winding core 51 of the upstream winding base 11 and the touch roller 16a of the downstream touch roller base 15, and is disposed on the outside of the film 150 in the width direction. There is. The charging unit 174 is disposed below the new winding core 51 of the upstream winding base 11 and charges the film 150 wound around the new winding core 51 of the upstream winding base 11. The air discharge section 175 is disposed below between the new winding core 51 of the upstream winding base 11 and the touch roller 16a of the downstream touch roller base 15, and is located on the upstream side with respect to the region in which the cutting blade 1711 runs. Air is blown onto the film 150 located there.

Next, the slider 1712b (see FIG. 3) of the rodless cylinder 1712 is moved along the cylinder body 1712a (see FIG. 3), thereby causing the cutting blade 1711 to travel in the width direction of the film 150. Therefore, the film 150 that is conveyed diagonally upward from the core 51 of the upstream take-up base 11 toward the touch roller 16a of the downstream touch roller base 15 is cut from one end in the width direction by the running cutting blade 1711. It is cut towards the other end. At this time, the charging section 174 attracts the film 150 to the new winding core 51 of the upstream winding base 11, and the air discharge section 175 causes the upstream cut end of the film 150 to be attached to the new winding core 51 of the upstream winding base 11. It is sprayed onto the wick 51.

Thereby, the cut film 150 is wound around the new winding core 51 of the upstream winding base 11. Note that the new core 51 is rotated counterclockwise, and the film 150 is wound around the new core 51. In this way, while winding the film 150, the core 51 around which the film 150 is wound is switched. That is, in this film winding device 100, when the winding core 51 is switched, the winding of the film 150 is performed without being stopped.

Thereafter, the take-up roll 151 on which the film 150 has been wound is discharged onto the loading platform. Further, the cutting mechanism 17, the downstream take-up base 12, and the downstream touch roller base 15 are returned to their original states.

By repeating the above operations, the film 150 is continuously wound while switching the winding core 51.

-effect-
In this embodiment, as described above, the cutting part 171 is provided in the link mechanism 172, so that the cutting part 171 is moved forward and backward by the swinging of the link mechanism 172, and the cutting part is moved forward and backward by the rotation of the arm. Compared to the case where the cutting section 171 is moved forward and backward, the space of the moving path can be saved. This makes it possible to shorten the distance between the winding core 51 on the downstream side and the new winding core 51 on the upstream side, thereby improving the winding quality when the film 150 is thin and easy to stretch. can be achieved.

Furthermore, in this embodiment, by shortening the distance between the downstream winding core 51 that is being wound and the new upstream winding core 51, the new winding core 51 of the upstream winding base 11 is The angular range of the film 150 to be wound becomes larger, and the cut film 150 can be easily wound around the new winding core 51.

Further, in this embodiment, by providing the charging section 174 and the air discharge section 175, the cut film 150 can be easily wound around the new winding core 51.

-Other embodiments-

Therefore, the technical scope of the present invention is not to be interpreted only by the above-described embodiments, but is defined based on the claims. Further, the technical scope of the present invention includes all changes within the meaning and scope equivalent to the scope of the claims.

For example, in the present embodiment, the upstream touch roller base 14 and the downstream touch roller base 15 are disposed below the upstream winding base 11 and the downstream winding base 12, and are connected to the film winding device 100 that performs lower winding. Although an example to which the present invention is applied has been shown, the invention is not limited to this, and the upstream touch roller base and the downstream touch roller base are arranged above the upstream winding base and the downstream winding base, and the film is top-wound. The present invention may be applied to a winding device.

Further, in this embodiment, the downstream touch roller base 15 is arranged on the downstream side (Y1 direction side) during winding, and the downstream touch roller base 15 is arranged on the upstream side (Y2 direction side) when switching the winding core 51. Although an example in which the touch roller base 15 moves in the upstream direction is shown, the present invention is not limited to this, and the downstream touch roller base 15 may be arranged in advance on the upstream side.

In the above embodiment, before the film 150 is cut by running the cutting blade 1711, the core 51 (core 51 of the downstream winding base 12) on which the film 150 is being wound is The touch roller 16a (the touch roller 16a of the downstream touch roller base 15) that presses the film 150 against the winding core 51 may be raised. In this way, the angular range of the film 150 wound around the new winding core 51 of the upstream winding base 11 can be made larger.
