When the liner is fully wound on the spool, the coil transfer device receives the liner coil from the support device and transfers the liner coil outward in the radial direction.

The liner coil transported by the coil transport device is lifted by a lifting device, moves upward from the transport device, and is separately transferred to a storage location by a discharging unit. A new empty spool is supplied from the spool transfer device to the coil transfer device from which the liner coil has been removed. Then, the coil carrying device carries the empty spool to the spool supporting device, the both ends of the spool are supported by the spool supporting device, and the next winding is performed.

Similarly, the liner rewinding device serves to co-roll the liner when the rolled material is wound up in the rolling coil material winding device. According to this liner rewinding device, both ends of the spool of the liner coil are rotatably supported by the spool supporting device at the liner rewinding position. Then, the end portion of the liner is inserted between the rolled materials, and the liner is rewound with the rolled material being wound.

When the liner is rewound and the spool is emptied, the coil transport device receives the emptied spool and transports the spool outward in the radial direction. The empty spool transported by the coil transport device is removed by the spool transport device and separately moved to a storage location. On the other hand, a new liner coil wound on the spool is placed on the elevating device, and the elevating device descends to deliver the liner coil to the coil transfer device. Then, the coil carrying device carries the liner coil to the spool supporting device, and both ends of the spool of the liner coil are supported by the spool supporting device, and the next rewinding is performed.

An air hole is formed at the axial center of the rod 51, and an air coupling 53 is axially slidably inserted at the tip of the air hole. The air coupling 53 is biased toward the tip side by a spring.

Then, as shown in FIG. 6, the extraction head 41 moves to the end of the spool 6 of the liner coil 7 supported by the elevating table 39. At that time, the air coupling 53 is coupled to the nipple 29 of the air shaft 9. Then, the rod 51 is moved in the axial direction by the cylinder 52, so that the pullout claw 45 is closed, and the projection 47 at the tip of the pullout claw 45 is engaged with the engagement groove 30 of the air cylinder 9. Compressed air is supplied to the air hole of the rod 51, and the air is supplied to the air shaft 9 through the air coupling 53 and the nipple 29 to immerse the friction key. The frictional contact between the air shaft 9 and the paper tube 8 is released by the immersion of the friction key.

After that, by retracting the pulling head 41, the air shaft 9 is pulled out from the paper tube 8. At this time, since the one end of the air shaft 9 is only clamped to the pull-out claw 45, the other end of the air shaft 9 falls when it is completely pulled out from the paper tube 8. To prevent this, a fall prevention device for holding the air shaft horizontally is provided (not shown).

The liner coil 7 from which the air shaft 9 has been pulled out is then moved upward by ascending and descending the elevating table 39, further removed from the elevating table 39 by a crane or the like, and transferred to another storage place.

The removed paper tube 8 moves to the clamp center position of the clamp link 55.

When the clamp link 55 clamps the paper tube 8 by the cylinder 56, the guide member 58 is moved outward in the left-right direction by the cylinder 59, and the paper tube holding of the holding plate 59 is released. Then, the holding plate 59 is retracted by the cylinder 60 to the original standby position. With the middle portion of the paper tube 8 held by the clamp link 55, the moving frame 53 moves forward, and the center of the paper tube 8 coincides with the center of the clamp arm 34 of the coil transfer device 11. The moving frame 53 stops.

After that, the pulling head 41 of the pulling device 40 holding the air shaft 9 moves to the paper tube side, and the air shaft 9 is inserted into the paper tube 8. Then, the pulling device 40 releases the clamp of the air shaft 9 to stop the air supply, so that the friction key projects and the air shaft 9 and the paper tube 8 are integrally connected. After that, the pull-out head 41 retracts to the standby position.
