Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band removing device for removing a band from a sheet of paper such as securities, and a method for removing paper from a polymerized sheet from which the band has been removed. The present invention relates to a sheet processing apparatus that takes out one sheet at a time, inspects the sheets, and sorts and accumulates sheets based on the inspection result.

[0002]

2. Description of the Related Art A banding stripper of this type stops a paper band at a predetermined position when a banding belt is removed by detecting a conveyed sheet bundle with a detecting device. The grip is curved to form a gap between the band and the sheet. Then, after inserting a pair of clamping arms into the gap between the band and the paper sheet to clamp the middle part of the band, the portion of the band located between the pair of band-clamping arms. Is cut with a cutter. Then, after this cutting, the pair of banding arms holding the banding band are moved by a distance necessary to release the bending of the paper sheet, and the banding band holding arm is stopped at that position. Then, the paper band is conveyed by the conveyer and the paper band is pulled out from the band to remove the band.

Conventionally, as a detecting device for detecting the above-described paper sheet, an optical detecting device including a light emitting element and a light receiving element is used, and the light emitted from the light emitting element is irradiated to the paper sheet. Then, by receiving the reflected light by the light receiving element, the boundary between the band and the paper sheet is detected to detect the position of the paper sheet bundle.

[0004]

However, in the prior art, the difference between the amount of light reflected from the surface of the paper sheet and the surface of the bandage using an optical detection device causes the difference between the paper sheet and the bandage. Since the position of the paper sheets was detected by detecting the boundary, if the paper sheets or the band were dirty, the boundary could not be detected or an area other than the boundary could be regarded as a boundary. There is a problem that the sheet bundle cannot be stopped at a predetermined position due to the detection.
