However, the present invention is not limited to this case, and can also be applied to a paper feeding device that is not provided with the web guide device 39.

In that case, it goes without saying that it is not necessary to make the lifting platform 50 movable left and right.

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 one 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 Bl of the lifting table 50a, so that the pallet 6 is transported onto the lifting table 50a, and then the first lifting table 50a is slightly raised. by holding the pallet 6 on the lifting platform 50a and then retracting the fork 80.

The pallet 6 can be transferred onto the lifting platform 50a.

Further, by performing the reverse operation, it is possible to transfer the pallet from the lifting platform 50a onto the unmanned cart 4a. In addition,
The other configurations are the same as those of the embodiment described above.

〔Effect of the invention〕

As explained above, according to the paper feeding method and apparatus of the present invention, the pallet on which the shaft holding the roll material is placed is transported by an unmanned cart to the front of the table lifter below the paper feeding device, and the pallet is is transferred together with the roll material onto the lifting platform of the table lifter, and then, by relative movement between the lifting platform and the turret arm, the shaft holding the roll material is held in the chucking device of the turret arm. This has the effect that it is possible to automatically feed the roll material to the paper feeder. Furthermore, unlike conventional vehicles, there is no need for the unmanned trolley to enter between the turret arms of the paper feeder, so there is no need to increase the size of the paper feeder. Furthermore, since the elevating platform of the table lifter can be retracted to the lowered position, various operations on the paper feeding device are not hindered.

Since a table lifter is installed in the paper feeder, this table lifter can be manually operated by button operation, so that it can be operated in the event of a failure of the automatic control device.
It has the advantage that the roll material supply operation can be performed by manual operation.
