[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a rewinding machine to rewind an original coil made of a wound long sheet,
In the device that sends the sheet to the processing line, the original coil can be easily and safely supplied to the rewinding machine, and more than one device can be managed by one person, thus saving labor. Sheet feeding device.

[0002]

2. Description of the Related Art A long sheet is wound and formed into a coil, which facilitates storage and transportation. The sheet body wound in a coil shape must be rewound in order to rework it, and a rewinding machine is provided upstream of the processing line for rewinding.

A rewinding machine is provided with a support shaft for inserting a plurality of coils on a plate-like body which is ordinarily oriented vertically, and rewinds a sheet one by one from a coil inserted in each support shaft to process the sheet body. It is configured to feed the line.

[0004]

When such a rewinding machine is used, every time the rewinding of one coil is completed, it is necessary to perform a setup change for taking out the sheet from another coil. Therefore, the rewinding work requires a manual operation such as constant inspection. Further, during the coil revolving operation due to the rewinding, a new coil must be replenished and loaded on the supporting shaft in the vicinity of the coil, which is difficult to work.

In order to solve one of the above problems, a plate body to which a plurality of support shafts are attached is made rotatable in a vertical plane.
Although the taking-out position of the sheet and the loading position of the coil can be fixed, the safety is enhanced, but it is necessary to constantly watch the replenishment of the coil, and labor saving has not been achieved.
