  Examples of the present invention will be described below.

  FIG. 1 shows a slitter winding device according to the present invention. In this apparatus, a winding shaft 1 is provided at each of two upper and lower winding positions, and after the web material is slit, the web material is distributed to the upper and lower winding shafts 1 and wound.

  Further, in this apparatus, the upper and lower winding shafts 1 are supported by a common side plate 2. Further, after winding the web material, the common side plate 2 moves in the axial direction of the winding shaft 1, and the upper and lower winding shafts 1 are pulled by the common side plate 2, so that the upper and lower winding shafts 1 are pulled. Is extracted from the wound product 3.

  In this embodiment, the side plates 2 are positioned at both ends of the winding shaft 1, and the upper and lower winding shafts 1 are supported by the side plates 2. Further, the upper and lower winding shafts 1 are divided into two in the axial direction, and the web material is wound on the upper and lower dividing shafts 1. Furthermore, in this embodiment, each side plate 2 is provided with a drive motor 4, and each motor 4 is connected to each divided shaft 1. Each motor 4 rotates each divided shaft 1, and the web material is taken up. It is done.

  Further, each side plate 2 is provided with a nut member 5, and the nut member 5 is screwed to a feed screw 6 and connected to a drive motor. The drive motor may be the motor 4 that rotates the split shaft 1 or may be another motor. Further, the side plate 2 is supported by the guide rail 7, and the feed screw 6 and the guide rail 7 extend in the axial direction of the winding shaft 1. Then, after winding the web material, each nut member 5 is rotated by the drive motor, and each side plate 2 is moved by the nut member 5 and the feed screw 6. The side plate 2 moves along the guide rail 7. Therefore, each side plate 2 moves in the axial direction of the winding shaft 1, each divided shaft 1 is pulled by each side plate 2, and each divided shaft 1 is extracted from the wound product 3.

  Further, in this embodiment, as shown in FIGS. 2 and 3, after the web material is wound, the table 8 is arranged at the upper and lower winding positions. For example, the upper and lower tables 8 are provided on a common carriage 9, and the upper and lower tables 8 are fed by the common carriage 9, and inserted into the upper and lower winding positions. Each table 8 can be raised and lowered by the lifter of the carriage 9 to adjust its height.

  Further, in this embodiment, on both sides of the take-up product 3, a plurality of width adjusting plates 10 move in the axial direction of the take-up shaft 1 and are pressed against the take-up product 3. 3 moves. For example, at the upper winding position, a pair of width-shifting plates 10 are arranged on both sides of the wound product 3, supported by the guide rail 11, connected to the chain 12, and the chain 12 is connected to the drive motor. The guide rail 11 extends in the axial direction of the winding shaft 1. The chain 11 has an upper portion and a lower portion, extends in the axial direction of the winding shaft 1, one width adjusting plate 10 is connected to the upper portion, and the other width adjusting plate 10 is connected to the lower portion. Yes. Then, the chain 12 is driven by the drive motor, and the width adjusting plates 10 are moved by the chain 12. The width adjusting plate 10 moves along the guide rail 11. Therefore, each width adjusting plate 10 moves in the axial direction of the winding shaft 1 and is pressed against the wound product 3, and the wound product 3 is moved by each width adjusting plate 10. The take-up product 3 moves along the take-up shaft 1 and is brought closer to the center position of the take-up shaft 1. Similarly, at the lower winding position, a pair of width adjusting plates 10 are arranged on both sides of the wound product 3, supported by the guide rail 11, and connected to the chain 12. Then, the chain 12 is driven by the drive motor, each width adjusting plate 10 moves in the axial direction of the winding shaft 1 and is pressed against the winding product 3, and the winding product 3 moves along the winding shaft 1. The width of the winding shaft 1 is increased.

  Furthermore, after the width of the wound product 3 is adjusted, each split shaft 1 is extracted from the wound product 3 as shown in FIG. Thereafter, the wound product 3 is taken out by the cart 9 and discharged.

  Therefore, in the case of this device, when the upper and lower winding shafts 1 are extracted from the wound product 3, unlike the device of Japanese Patent Application Laid-Open No. 2004-256230, the upper and lower winding shafts are pulled by individual holding devices. There is no need. When the common side plate 2 is moved in the axial direction of the winding shaft 1 after winding the web material, the upper and lower winding shafts 1 are pulled by the common side plate 2 to wind the upper and lower winding shafts 1. It can be extracted from the product 3 and its configuration is simple and the cost is low.

  Furthermore, in this apparatus, after the width of the wound product 3 is reduced, it is supported on each table 8. As a result, the table 8 and the carriage 9 can be made compact. When discharging the wound product 9, it can also be stabilized.

  FIG. 5 shows another embodiment. In this embodiment, the winding shaft 1 is not divided into two. Further, the upper and lower winding shafts 1 are supported by the common side plate 2 at one end of the winding shaft 1, and the bearing 13 is provided on the bracket 14 at the other end, as shown in FIG. The upper and lower winding shafts 1 are inserted into the bearing 13 and supported. Further, the drive motor 4 is provided on the common side plate 2 and is connected to the upper and lower winding shafts 1, and the upper and lower winding shafts 1 are rotated by the drive motor 4 to wind the web material. .

  Further, a nut member 5 is provided on the common side plate 2, screwed to the feed screw 6, and connected to the drive motor. Then, after winding the web material, the common side plate 2 is moved by the drive motor, the nut member 5 and the feed screw 6. The side plate 2 moves along the guide rail 7. Therefore, the upper and lower winding shafts 1 are pulled by the common side plate 2, and the upper and lower winding shafts 1 are extracted from the bearing 13. Thereafter, the upper and lower winding shafts 1 are extracted from the wound product 3.

  Further, in the embodiment shown in FIG. 5, after the web material is wound, the table 8 is arranged at the upper and lower winding positions. Accordingly, the upper and lower winding shafts 1 are extracted from the wound product 3, and the wound product 3 is supported by each table 8. On both sides of the take-up product 3, a plurality of width adjusting plates 10 are moved in the axial direction of the take-up shaft 1, pressed against the take-up product 3, and the take-up product 3 is moved along the take-up shaft 1. You may make it width-align to the center position of the axis | shaft 1. FIG. For example, the chain 12 is driven by a drive motor, the width adjusting plate 10 is moved, and the wound product 3 is width aligned to the center position of the winding shaft 1. Thereafter, the upper and lower winding shafts 1 may be extracted from the wound product 3 so that the wound product 3 is supported by each table 8.
