Normally, as shown in FIG. 11 (a), a web from a printing press is wound on a winding roll 5 at one end of a turret arm 17 of a winding device, and a new end is provided on the other end of the turret arm 17. A simple paper tube 5b is mounted. At this time, the lift 50 of the table lifter 3 is in the lowered standby position, and the lift 50 is held at the center by the centering device 63 (see FIG. 7). At an appropriate timing, for example, simultaneously with the splicing on the paper feed side, the turret arm rotates, and the rewinding device 41 operates to wind the web onto a new paper tube. Thereafter, the web is wound on a new paper tube to form a new winding roll 5a (see FIG. 11 (b)).

Next, the turret arm 17 rotates to the position shown in FIG. 11 (b), and holds the take-up roll 5 to be discharged at the upper position. At the same time, the unmanned trolley 4 carrying the empty pallet 6 travels to the front of the table lifter 3 of the winding device 2,
The vehicle stops at a predetermined position and is positioned and fixed by the positioning device shown in FIG. 10B.

Next, the lift 50 of the table lifter 3 is raised to the pallet transfer position at the same height as the unmanned trolley 4. When the lifting platform 50 rises to the pallet transfer position and stops, the unmanned carriage 4 and the roller conveyors 12 and 52 on the lifting platform 50 rotate in the same direction, and the empty pallet 6 is moved as shown in FIG. 11 (c). It is transferred onto the lifting platform 50. The pallet 6 is moved from the pallet stopper 54 on the elevator 50
And stops, the roller conveyors 12, 52 stop rotating. At the same time, the pallet fixing means 55 (see FIG. 6B) operates to hold the pallet 6 pressed against the pallet stopper 54. As a result, the pallet 6 is positioned and fixed at a predetermined position on the lift table 50.

Next, as shown in FIG. 11 (d), the elevating platform 50 descends to the lower limit, and the turret arm 17 rotates to the horizontal take-up roll transfer position and stops.

Thereafter, the lift 50 rises. When the lift 50 reaches a predetermined height position (where the pallet 6 is lower than the take-up roll 5), it temporarily stops. next,
When the centering device 63 (see FIG. 7) is opened,
And the web guide tuning device 70 (see FIG. 3) operates to restrain the elevator 50. As a result, the elevator 50 moves integrally with the web guide device 39 supporting the turret arm 17, and although the turret arm 17 moves left and right for web edge control, the elevator 50 moves. Are maintained in a fixed positional relationship with the turret arm 17.

Next, when the elevator 50 starts to rise and the pallet 6 almost contacts the winding roll 5 as shown in FIG.
The switch 53 (see FIG. 5B) detects this, and the elevator 50 stops. Next, the chucking of the winding roll is released, and the winding roll 5 is placed on the pallet 6.

Then, after the web guide tuning device 70 is released and the centering device 63 is operated to position the elevator 50 at the center position, as shown in FIG. 11 (f), the elevator 50 is moved to the pallet transfer position. To rise. Next, as shown in FIG. 11 (g), the roller conveyors 12, 52 rotate in the opposite direction to the previous one, and transfer the winding roll 5 on the elevating table 50 together with the pallet 6 onto the unmanned carriage 4. After sending out the pallet 6, the lift 50 returns to the lower standby position.

On the other hand, the unmanned trolley 4 carrying the take-up roll 5 runs and stops beside the fixed station 7. Next, unmanned trolley 4
Then, the roller conveyors 12 and 8 of the fixing station 7 rotate in the same direction, and the winding roll 5 is transferred onto the fixing station 7 together with the pallet 6.

Thus, the take-up roll discharge operation for removing the take-up roll from the take-up device and conveying the take-up roll to a predetermined position is completed. In the winding device, an empty paper tube is manually attached to the chucking device after the take-up roll 5 is removed at an appropriate time to prepare for the next winding operation.

In the above embodiment, as shown in FIGS. 11 (d) and 11 (e), the elevator 50 on which the pallet 6 is placed is lowered, and the turret arm 17 is moved to the take-up roll transfer position (horizontal position). After stopping, the elevator 50 is moved to the pallet 6 by the winding roll 5.
Instead, the lifting table 50 on which the pallet 6 is placed is positioned at the position where the take-up roll is received from the turret arm (the take-up roll transfer position). The turret arm 17 is rotated, and the take-up roll 5 is
Alternatively, the turret arm 17 may be stopped when the switch 53 detects the take-up roll 5 and stopped.

Further, in the above embodiment, the web guide device 39 is provided in the winding device 2, and the winding roll and the turret arm 17 holding the same are moved right and left for controlling the end surface of the winding roll. This turret arm
In order to make the elevator 50 follow the movement of 17, the elevator 50 can be moved to the left and right, and a web guide tuning device 70 is provided. However, the present invention is not limited to this case, and can be applied to a winding device without the web guide device 39. In that case, it is not necessary to make the elevator 50 movable left and right. Needless to say.

Further, in the above embodiment, as a 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. 12 and 13 show an embodiment in which a fork device is used to transfer the pallet 6. FIG. Unmanned trolley 4a

The pallet 6 is held by the pallet 6 and the fork 80 is inserted into the groove 81 of the elevator 50a.
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.

14 and 15 show another embodiment. In this embodiment, an unmanned trolley 4b is provided with a fork device provided with a fork 82 having a shallow V-shaped recess formed on the upper surface thereof. On the other hand, the lifting table 50b has a groove 8 through which the fork 82 passes.
3, and a shallow V-shaped recess is formed on the upper surface. In this case, the take-up roll 5 is directly lowered onto the lifting table 50b without using a pallet for transport of the take-up roll 5, and the take-up roll 5 is directly held by the fork 82 and transferred onto an unmanned carriage. Can be posted. The elevator 50b
The recess on the upper surface also serves as a means for positioning the take-up roll 5 at a predetermined position, and therefore, in this embodiment, it is not necessary to provide a pallet stopper.

〔The invention's effect〕

Further, since the unmanned bogie does not need to enter between the turret arms of the winding device, there is no need to increase the size of the winding device. Further, since the lifting platform of the table lifter can be retracted to the lowered position, there is no problem in various operations in the winding device. In addition, since a table lifter is provided below the take-up device, the table lifter can be manually operated by button operation. If the automatic control device breaks down, the take-up roll can be removed manually. Can be performed.
