Although not shown, an operation panel for manually operating each conveyor and table lifter, a sequence controller for performing an automatic winding supply operation described later, and various sensors used for the sequence control. Is provided.

Next, the operation of the apparatus having the above structure will be described.
First, an operator with a machine performs a winding preparation and a storage operation at an appropriate time during a normal operation of the processing machine (during unwinding of the winding held by the sheet feeding device 1). That is, the pallet is placed on the third conveyor 17, and the roll with the paper splicing preparation such as the paste is put on the pallet, or the web splicing is prepared on the pallet. Next, the pallet with the winding is transferred from the third conveyor 17 to the second conveyor 12. At this time, the second conveyor 12 is naturally oriented so that it can receive the pallets from the third conveyor 17. After that, the second conveyor 12 is turned 90 degrees toward the storage conveyor 9, and the pallet is sent to the storage conveyor 9, and the storage conveyor 9 sends the pallet onto the first conveyor 7. Next, by the same operation, a new winding is prepared on another pallet and sent out onto the storage conveyor 9. Further, a new winding is prepared on another pallet and placed on the second conveyor 12. As described above, the three windings placed on each pallet are prepared and stored on the first conveyor 7, the storage conveyor 9, and the second conveyor 12.

The windings thus stored are automatically supplied to the paper feeding device when the number of windings 4 held by the paper feeding device 1 and feeding the web becomes small. The operation will be described below. First, when the winding amount of the paper feeding device 1 becomes low, the first conveyor moving device 8 moves the first conveyor 7 to below the empty chucking cone 3b of the paper feeding device 1 and holds it on it. The center of the winding is positioned directly below the chucking cone 3b. Then, the first table lifter 6 rises to position the center of the winding 4 at the same level as the chucking cone 3b, and then the chucking cone 3b holds the winding.

After passing the winding to the chucking cone 3b, the first conveyor 7 is retracted to its original position with an empty pallet placed thereon, and the first table lifter 6 returns the first conveyor 7 to the pallet. It descends so that it becomes the same level as the conveyor 10. Next, the first conveyor 7 sends the empty pallet to the pallet return conveyor 10. After that, the first table lifter 6 rises again and positions the first conveyor 7 at the same level as the storage conveyor 9. Then, the winding on the pallet is supplied from the storage conveyor 9 onto the first conveyor 7 to prepare for the next winding supply to the paper feeding device. At this time, the windings that were on the second conveyor 12 at the same time are sent to the storage conveyor 9.

In the paper feeding device 1, the winding operation is switched immediately before the winding operation is stopped while the web is being unwound, and the web is unwound from a new winding operation. After that, the residual core is discharged by an appropriate means. The remnant core may be discharged onto the pallet that has been previously wound and may be conveyed by the pallet.

When the take-up while the paper feeding device 1 is unwinding becomes small, the take-up held on the first conveyor 7 is supplied to the paper feeding device and the pallet emptied is removed, as described above. It is discharged onto the pallet return conveyor 10. At this time, the second conveyor 12 is at the same level as the pallet returning conveyor 10 by the second table lifter 11, and the pallet previously discharged onto the pallet returning conveyor 10 is discharged onto the second conveyor 12. . The second conveyor 12 that has received the pallet is raised to the same level as the storage conveyor 9 and the third conveyor 17 by the second table lifter 11 and discharges the pallet to the storage conveyor 9 or the third conveyor 17.

By repeating the above operation, the windings previously stored on the first conveyor 7, the storage conveyor 9 and the second conveyor 12 are automatically supplied one after another to the paper feeding device 1 to obtain an empty pallet. Is returned to the storage conveyor 9 or the third conveyor 17 through the pallet return conveyor 10. After the previously stored winding is used up, a new winding may be prepared and stored again.

As described above, in the above-described automatic winding conveying device, the necessary winding preparation work is performed for three windings in advance and the windings are stored, so that the three windings are successively taken. The paper can be automatically supplied to the paper feeding device 1, and unmanned work can be performed during the period until the three windings are used up. In this embodiment, one pallet is stored on the storage conveyor 9, but the length of the storage conveyor may be increased to store two or more pallets.

In the above embodiment, the second conveyor 12 has a rotatable structure, but the present invention is not limited to this structure so that the second conveyor 12 can simply convey the pallet in the Y-Y axis direction. It may be fixedly provided at. However, if the second conveyor 12 is configured to be rotatable as in the illustrated embodiment, the third conveyor 17 can be arranged at the position shown by the solid line, and the width direction of the sheet feeding device of the automatic winding device 5 is increased. The advantage that the installation space (distance L in FIG. 1) can be reduced is obtained. In addition, the third conveyor 17 is not limited to the position shown in the figure, and there is an advantage that the third conveyor 17 can be arranged at any desired position around the second conveyor 12. Further, in the above embodiment, the storage conveyor 9 conveys the pallet 15 toward the first table lifter 6, and the pallet return conveyor 10 conveys the pallet 15 toward the second table lifter 11. One or both of the storage conveyor 9 and the pallet return conveyor 10 may be capable of conveying the pallet in both forward and reverse directions. With such a configuration, the pallet can be conveyed in the opposite direction to that described in the above embodiment, if necessary. For example, an empty pallet on the pallet return conveyor 10 can be moved to the first table lifter 6 It is possible to send the residual core from the sheet feeding device 1 onto the empty conveyor 7 and to operate the empty pallet. In addition, if the distance between the storage conveyor 9 and the pallet return conveyor 10 is increased, it is possible to store the pallet with the winding on the pallet return conveyor 10 and increase the number of storage windings. Becomes

[0024]

As described above, according to the automatic winding device of the present invention, a plurality of rolls, which are prepared for splicing in advance, are placed on a pallet and stored, so that the rolls are processed. It is possible to successively supply the paper to the paper feeding devices, and it is possible to automatically supply the paper to the paper feeding devices for a certain period (until the winding is no longer stored). Moreover,
Since the pallet return conveyor is arranged under the storage conveyor, the installation area can be reduced. Further, since the storage conveyor (pallet return conveyor) and the second conveyor are arranged laterally with respect to the first conveyor arranged on the central axis of the paper feeding device, a long space is provided behind the paper feeding device. It is not necessary and has the effect that it can be installed in a place with a horizontal space.
