The winding device of this embodiment is configured as described above.

Next, the operation when winding up the felt 8 as the band-shaped body 8 using this winding device will be explained.

First, insert the paper tube 6 into which the core metal 60 is inserted into the guide member 2.
It is placed on the guide surface 22 of No. 1. And drive motor 1
When the switch 6 is turned on, the front drive roller 11 and the rear drive roller 12 are driven, and the tip of the felt 8 is supplied onto the front drive roller 11. When the tip of the felt 8 advances from the front drive roller 11 onto the rear drive roller 12, the swing arm 251 is driven by the drive motor 254. This allows the guide surface 22 to move forward to the front drive roller 11.
The guide member 21 moves to a position facing the rear drive roller 1.
2 along the outer circumferential surface 12b.

Then, the core bar 60 and the paper tube 6 placed on the guide surface 22 are transferred onto the tip of the felt 8, and the tip of the felt 8 is bent into a dogleg shape due to the weight of the core bar 60 and is driven backward. It floats up from the outer peripheral surface 12b of the roller 12. At this time, air is ejected from the air nozzle 23 opening in the guide surface 22, urging the tip of the felt 8 in a direction away from the outer circumferential surface 12b of the rear drive roller 12. When the felt 8 is conveyed by the driving of the front drive roller 11 and the rear drive roller 12, its tip advances while being guided along a guide surface 22 having a semicircular cross-sectional shape. Then, when the tip of the felt 8 passes through the guide surface 22 and surrounds the outer peripheral surface of the paper tube 6, the swinging piece 255 swings due to the operation of the air cylinder 256, and the pressing member 257 protrudes. . As a result, the tip of the felt 8 is pressed between the inner surface of the felt 8 and the outer circumferential surface of the paper tube 6, and the felt 8 becomes ready for subsequent winding (
(See Figure 3). Note that when the pressing member 257 is returned by the air cylinder 256, the swinging arm 251 swings due to the operation of the drive motor 254, thereby returning the guide member 21 to its initial position. On the guide surface 22 of this guide member 21 are a core bar 60 and a paper tube 6 to be used next.
is placed in preparation for the next operation.

Immediately after becoming ready for winding as described above, the front drive roller 11 and the rear drive roller 12 are driven, so that the continuously supplied felt 8 is wound around the paper tube 6. At this time, the core metal 60 is guided by the guide groove 311 of the kicking arm 3 and moves upward as the amount of winding of the felt 8 increases. Moreover, since both ends of the core bar 60 are urged downward by the presser brackets 41, the felt 8 is wound up uniformly in the left and right width directions. After winding up to the rear end of the felt 8, the side wall 313 of the vertical portion 31
is slid outward by the air cylinder 35, so that the core bar 60 can be removed from the guide groove 311. Next, the air cylinder 34 is operated to swing the kicking arm 3 around the shaft bearing toward the rear drive roller 12, and the wound felt 8 is sent onto the prepared cart. Thereafter, the operations described above are repeated, and the felt 8 is wound up by the winding device.

As described above, in the winding device of this embodiment, the guide member 21
Since the tip of the felt 8 is guided by the guide surface 22 and wound around the paper tube 6, complicated manual work by the operator is not required.

Therefore, winding work can be performed efficiently and productivity can be improved.

In addition, the guide member 21 having the guide surface 22 also serves as a member for placing the paper tube 6 and the core metal 60 to be fed onto the tip of the felt 8, so that the preparation work can be carried out continuously and efficiently. In addition, it is possible to simplify the structure and reduce costs.

Furthermore, the winding device of this embodiment includes a pressing member 257 that presses the tip of the felt 8 between the inner surface of the felt 8 and the outer peripheral surface of the paper tube 6, so that the tip of the felt 8 can be wound more reliably. It can be performed.
