Furthermore, it is equipped with a control device that operates each device in conjunction with each other.

Next, the operation will be described. The apparatus of the embodiment operates as shown in the diagrams of the interrelated operation sequence of each part shown in FIGS. 9a to 9f and the flowchart of FIG. 10. Now, in response to the paper splicing completion signal, the support arm 19 rotates to the remaining core collection position and is stopped by the detector LS1, and the remaining core collection device C installed directly below the remaining core collection position begins to rise, and the remaining core receiver The portion 33 comes into contact with the remaining core 22, the detector LS3 is activated, and the upward movement is stopped. Then, the unwinding of the remaining core 22 that has been unwound after paper splicing is transferred to the unwinding roller 34 of the remaining core collecting device C.
It is rewound by

The rotation time of the unwinding roller can be adjusted according to the unwinding length using a timer. When rewinding is completed, the center cone 2 of the web loading device

Next, after the center cone 20 retreats, the remaining core collection device C descends to the remaining core delivery position and waits. At the same time, the support arm 19 from which the remaining core 22 has been removed rotates to the new web chucking position, stops in response to a signal from the detector, and receives the new web chucking position.
Wait for 1a to be supplied.

On the other hand, the new roll paper 21a is sent from the paper warehouse to the trolley A.
It is mounted on the stand 32 and conveyed through the first rail 31 toward the carry-in rail 30 on the traverser B. The trolley A carried onto the traverser B is pulled onto the traverser B by a trolley retracting device (not shown) built into the traverser B, and then the trolley A is pulled onto the traverser B by a photoelectric sensor for positioning in the mounting width direction provided above the starting position of the traverser B. switch
When the new web 21a on the trolley A blocks the light trace of X', the trolley pull-in position is stopped and the new web 21a is accurately positioned.

When the positioning of the new web 21a in the installation width direction is completed, the traverser B starts moving from the start position toward the depth direction of the reel (in the direction of arrow F1 in FIG. 5), and moves to the installation height positioning position of the new web 21a. It stops at the chucking position and the start position (same as the unloading position). In order to accurately stop the traverser B at each of the above positions,
Detectors LS6, LS8 installed in front of each stop position,
When the actuating piece 43 of traverser B hits LS10,
The speed of the motor 35 of traverser B becomes low,

9. The actuation piece 43 strikes the LS11 in the same manner as above,
It is stopped accurately by the brake of the moving motor 35. Another method for determining the stop position is to move the robot forward by inching from just before the stop position and stop it accurately at the stop position.

The traverser B stopped at the installation height alignment position by the traverser moving and positioning device, and after stopping, the main lifter 27 starts to raise the traverser B, and the new web 2
When the light traces of the photoelectric switches Z and Za for positioning the installation height pass through the hollow part of the paper tube 1a, it stops rising.
After stopping the rise, the traverser B moves forward to the chucking position as described above and the positioning is completed, and the center cone 20 of the roll paper mounting device moves forward and bites into the hollow part of the paper tube of the new roll paper 21a, completing the mounting. . At that time, after detecting that the center cone 20 of the paper roll mounting device has entered the hollow part of the paper tube, the main lifter 2 of the traverser B
7 is lowered and the installation is completed.

After that, the remaining core 22 removed from the support arm 19 after paper splicing is received, and the remaining core transfer arm 38 of the remaining core collecting device C, which has been on standby, operates, and the remaining core 22 is transferred to the remaining core temporary receiver 28 on the traverser B. It is handed over. When the transfer of the remaining core 22 is completed, the traverser B retreats toward the starting position, and the detector
The action of LS10 and LS11 allows it to stop accurately at the starting position.

The remaining core temporary receiver 28 is moved to the trolley A by the lifter 29.
It rises to the same height as the top surface of the platform 32 of the trolley A, and at the same time as it rises, the remaining core 22 is transferred onto the platform 32 of the trolley A by the arm 39. When the delivery of the remaining core 22 is completed, the trolley A is carried out to a predetermined position by the retracting device of the traverser B, and conveyed to the paper warehouse through the rail 31 connected to the rail 30 of the traverser B, where the roll paper is automatically loaded. The cycle is complete.

Next, FIG. 11 shows another embodiment. In the device shown in FIG. 5, a temporary core support 28 is provided on the traverser B, and the core 22 removed from the support arm 19 by the core recovery device C is once removed. In the embodiment shown in Fig. 11, a remaining core receiving arm is provided on the side of trolley A, and after the traverser B has returned to the starting position, the remaining core receiving arm is installed on the side of trolley A, and after the traverser B has returned to the starting position, it is transferred to the trolley A. Hand over the remaining core directly from C to Trotsko,
Immediately after traverser B returns to the starting position, trolley A is carried out from above traverser B toward the paper storage.

FIG. 12 shows still another embodiment, in which the transfer arm 38 of the remaining core collecting device is lengthened so that it is directly transferred from the remaining core collecting device C to the trolley A, and the traverser B is at the starting position. Immediately after returning to , trolley A is carried out from traverser B toward the paper storage. Figures 11 and 12 above
In the embodiment shown in the figure, the remaining core is transferred directly from the remaining core collecting device C to the trolley A. Therefore, after the traverser B returns to the starting position, the trolley A can be immediately carried out toward the paper storage. The time required can be shortened.

FIG. 13 shows a comparison between the conventional device (FIG. 1) and the device of the present invention (FIG. 5). As shown in this figure, the present invention has the following effects. In other words, the removal of the remaining core from the support arm,
Since this can be done while rotating to the chucking position after paper splicing is completed, it can be done in parallel with pulling the trolley into the traverser, reducing the time required to install a new web after receiving instructions from the operator. It's short. Therefore, since the printing speed of rotary printing presses has become faster, it is possible to carry out shorter mounting operations with more time. Further, according to the present invention, the used remaining core is received from the chucking device, and after the traverser returns to the starting position, the traverser automatically passes the remaining core to the trolley without bothering the operator, and places the remaining core on the trolley. It can be transported to the collection location, and there is no need for the operator to perform dangerous work. In addition, since the paper that has come undone during paper splicing can be rewound by the unwinding roller and the remaining core can be collected, there is no possibility that unraveled pieces of paper will be scattered around.
