In this state, the turret arm 17 rotates in the direction indicated by the arrow in FIG. 15 (j), and the roll material 5 is inserted into the shaft support groove 28A (see FIG. 5) located in front of the chucking shafts 21 and 31. The end of the held shaft 9 is received and scooped up to the position shown in FIG. 15 (k). Next, the chucking device operates at that position to chuck the shaft 9 holding the material roll 5.

On the other hand, in the table lifter 3, as in the previous case, the web guide tuning device 70 is released, and the centering device 63 is operated to position the elevator 50 at the center position, and then the elevator 50 is moved to the pallet transfer position. As shown in FIG. 15 (n), the roller conveyors 12 and 52 rotate in the opposite direction to the last time to move the pallet 6 on the elevator 50 to the unmanned trolley. Return to 4.

After that, the unmanned trolley 4 travels to the position where the residual core is discharged,
On the other hand, in the table lifter 3, the elevating platform 50 is lowered to the retreat position, and the turret arm 17 returns to the normal web supply state.

Thus, the operation of supplying the new material roll to the sheet feeding device is completed. In the sheet feeding device, when the remaining amount of the material roll 5a reaches a predetermined amount, a splicing operation is performed by a known method, and switching to a new material roll 5 is performed.

In the above embodiment, the residual core recovery and the supply of the new roll material are performed on the same pallet. However, the present invention is not limited to this case. It may be performed on a pallet or a separate unmanned cart. Also,
The residual core recovery is not particularly limited to the above-described method, and may be performed by a manual operation or the like.

Further, in the above embodiment, the pallet transfer position and the roll material transfer position are set at different heights. However, the height may of course be the same, and in this case, the positioning operation of the lift 50 is naturally simplified. Become.

In the above embodiment, as shown in FIGS. 15 (j) and 15 (k), the turret arm 17 is rotated in the direction of the arrow after the elevator 50 holding the pallet 6 is positioned at the predetermined shaft transfer position. As a result, the shaft 9 on the pallet 6 is held by the chucking device of the turret arm 17, but instead, the elevator 50 is raised, and the turret arm 17 is moved to the shaft transfer position where the turret arm 17 becomes almost horizontal. The shaft 9 on the pallet 6 may be held by the chucking device of the turret arm 17 by positioning and stopping, and then lowering the elevator 50. Similarly, the remaining core 5b held on the turret arm 17 is
When transferring to the upper pallet 6, the turret arm 17
The turret arm is positioned by moving the turret arm to the shaft transfer position and stopping.
The residual core holding shaft held by 17 may be put on a pallet.

In order to make the lift 50 follow the movement of the turret arm 17, the lift 50 can be moved left and right and a web guide tuning device 70 is provided. However, the present invention is not limited to this case.
The present invention can be applied to a sheet feeding device not provided with the web guide device 39. In this case, it is needless to say that the elevator 50 need not be movable left and right.

Further, in the above embodiment, as means for transferring the pallet 6 between the unmanned trolley 4 and the lift 50 of the table lifter 3, a conveyor is provided for each of the unmanned trolley 4 and the lift 50. It is also possible to use alternative means. FIGS. 16 and 17 show an embodiment in which a fork device is used to transfer the pallet 6. FIG. Unmanned trolley 4a

The pallet 6 is conveyed onto the pallet 6, and then the pallet 6 is held by the elevator 50 a by slightly raising the elevator 50 a.
The pallet can be transferred onto the unmanned trolley 4a from the elevating platform 50a by the reverse operation. Other configurations are the same as those of the above-described embodiment.

〔The invention's effect〕

As described above, according to the paper feeding method and apparatus of the present invention, a pallet carrying a shaft holding a material roll is transported by an unmanned cart to a table lifter below the paper feeding device, and the pallet is transferred to the pallet. The roll is transferred together with the roll onto the lift of the table lifter. After that, the shaft holding the roll is held by the turret arm chucking device by relative movement between the lift and the turret arm. This has the effect that the material roll can be automatically supplied to the sheet feeding device. Further, unlike the related art, the unmanned trolley does not need to enter between the turret arms of the sheet feeding device, so that it is not necessary to enlarge the sheet feeding device. Further, since the lifting platform of the table lifter can be retracted to the lowered position, there is no trouble in various operations in the sheet feeding device. In addition, since the table lifter is provided in the paper feeder, the table lifter can be manually operated by button operation, so that when the automatic control device breaks down, the roll material supply operation is performed manually. It has the effect that it can be performed.
