Next, the unmanned cart 4 carrying the pallet 6 travels in front of the table lifter 3 of the winding device 2, stops at a predetermined position, and is positioned and fixed as shown in FIG. 12B.

At this time, as shown in FIG. 15 (bl), the empty paper tube 5b is placed on the shaft holder on the far side from the winding device (hereinafter, in order to distinguish it from the other shaft holder, this shaft holder will be referred to as tOa, and the other as 1Ob). (shown) tOa, and the other shaft receiver 10b is empty.

In parallel with or after the arrival of the unmanned cart 4, the five turret arms 17 rotate to the winding roll discharge standby position shown in FIG. 15(bl), and the chucking device 18. 19 (see FIG. 4) is released, that is, the 9 chucking shaft 21.31 is retracted.

As shown in FIG.
8A (only one shown).

Next, the lifting platform 50 of the table lifter 3 rises to a pallet transfer position at the same height as the unmanned cart 4. When the elevating platform 50 rises to the pallet transfer position and stops, the unmanned cart 4 and the roller conveyor 12,527'l on the elevating platform 50 rotate in the same direction and move the pallet 6 onto the elevating platform as shown in FIG. 15 (C1). When the pallet 6 hits the pallet stopper 54 (see Fig. 10) on the lifting platform 50 and stops, the roller conveyor 12.52 stops rotating.At the same time, the pallet fixing means 55 is activated. The pallet 6 is held in a state pressed against the pallet stopper 54. Thereby, the pallet 6 and the take-up roll 5 thereon are positioned at a predetermined position on the lifting table 50.

As a result, the elevating table 50 moves together with the web guide device 39 supporting the turret arm 17, and even though the turret arm 17 is moving left and right to control the end face of one take-up roll, the elevating table 50 moves up and down. The platform 50 is maintained in a constant positional relationship with respect to the turret arm 17.

Next, the turret arm 17 rotates in the direction shown by the arrow in FIG.

The turret arm 17 connects the shaft 9 to the shaft receiver lOb.
After passing it to , it stops at a position slightly below it (the position shown at f8+ in Fig. 15).

Next, the web guide tuning device 70 is released, and the centering device 63 is operated to position the lifting platform 50 at the center position, and then the lifting platform 50 rises to the pallet transfer position (see FIG. 15 (fl)). Next, as shown in FIG. 15 (gl), the roller conveyor 12.52 rotates in the opposite direction from the previous time and returns the pallet 6 on the lifting platform 50 to the unmanned cart 4.

Thereafter, the unmanned trolley 4 is turned around by 180 degrees by a suitable means 1, such as a spin turn, and is again positioned in front of the table lifter 3. At this time, Fig. 15 (hl

Then, the chucking device operates at that position to chuck the shaft 9 holding the one-winding roll 5.

On the other hand, in Table Lifter 3, as before,
After the web guide tuning device 70 is released and the centering device 63 is activated to position the lifting platform 50 at the center position, the lifting platform 50 is raised to the pallet transfer position.
(See Figure 5 tm+) 5 Next, as shown in Figure 15 (nl)
The roller conveyor 12.52 rotates in the opposite direction from the previous time and returns the pallet 6 on the lifting platform 50 to the unmanned cart 4.

Thereafter, the unmanned trolley 4 travels to the fixed station 7 to store the winding roll 5 thereon, and unloads the winding roll 5 together with the pallet thereon.

In the table lifter 3, the lifting platform 50 is lowered to the retracted position, and the turret arm 17 returns to the normal web winding state (see FIG. 15(0)).

In the 0-winding device where the operation of discharging the winding roll from the winding device and the operation of supplying the empty paper tube are completed, the rewinding operation is performed at an appropriate timing, for example, at the same time as paper splicing on the paper feeding side, using a known method. The web is then switched to the empty paper tube 5b-L.

In one or more embodiments, the conveyance of the first take-up roll 5 and the supply of empty paper tubes are carried out using the same pallet, but the present invention is not limited to this case. It is also possible to use separate pallets and separate unmanned trolleys. Further, the empty paper tube supply is not particularly limited to the above-mentioned method, and may be performed by one manual operation or the like.

Further, in the above embodiment, the pallet transfer position and the shaft transfer position are set at different heights, but they may of course be set at the same height, in which case the positioning operation of the lifting platform 50 will naturally be simplified. .

In addition, in the above embodiment, as shown in FIG. A method is adopted in which the shaft 9 is placed on the shaft holder 10b of the pallet 6, but instead of this, the lifting platform 50 is lowered, the turret arm 17 is positioned and stopped at a substantially horizontal shaft transfer position, and then the lifting The shaft 9 held by the turret arm 17 may be placed on the shaft receiver 10b of the pallet 6 by raising the platform 50.

In the embodiment described above, a web guide device 39 is provided in the winding device 2, and the winding roll that is being wound one time and the turret arm 17 holding it are moved left and right in order to control the end face of one winding roll. In order to make the lifting platform 50 follow the movement of the turret throat arm 17, the lifting platform 50 is
0 can be moved left and right, and the web guide tuning device 7
0 is set. However, the present invention is not limited to this case, but can also be applied to a winding device that is not provided with the web guide device 39, and in that case, it is not necessary to make the lifting platform 50 movable left and right. Needless to say.

Furthermore, in the above embodiment, a conveyor is provided in each of the unmanned cart 4 and the lifting platform 50 as a means for transferring the pallet 6 between the unmanned cart 4 and the lifting platform 50 of the table lifter 3. It is also possible to use alternative means. 16 and 17 show an embodiment in which a fork device is used to transfer the pallet 6. FIG. The unmanned trolley 4a is equipped with a fork device having a fork 80 that can protrude laterally, and the lifting platform 50a has a groove 81 through which the fork 80 passes. In this embodiment, the pallet 6 is held by the fork 80, and the fork 80 is inserted into the groove 81 of the lifting table 50a, so that the pallet 6 is transported onto the lifting table 50a, and then the lifting table 50a is slightly raised. By doing so, the pallet 6 can be held on the lifting table 50a, and then the pallet 6 can be transferred onto the lifting table 50a by retracting the fork 80. By this reverse operation, it is possible to transfer the pallet from the lifting platform 50a onto the unmanned cart 4a. Note that the other configurations are the same as those of the embodiment described above.

The shaft of the winding roll held by the turret arm can be placed on the pallet, and the pallet is then returned to the original unmanned trolley and carried to a predetermined position by the unmanned trolley, thereby removing the winding from the second winding device. This has the effect that the take-up roll can be automatically discharged. Furthermore, since the unmanned truck does not need to enter between the turret arms of the two winding devices, there is no need to increase the size of the first winding device. Furthermore, since the lifting platform of the table lifter can be retracted to the lowered position, various operations on the single winding device are not hindered.
In addition, since a table lifter is provided in the S-fitting device, this table lifter can be manually operated by button operation, so that when the automatic control device malfunctions, the take-up roll can be ejected with one manual operation. It has the effect of being able to do the following.
