Abstract
A sheet sorting device according to an embodiment includes a transporting unit that transports a sheet. A reading unit generates an image of a surface of the sheet. A decoloring unit performs a decoloring processing to decolor an image on the sheet. The sheet sorting device includes a plurality of sheet stacking trays. A processor causes the reading unit to generate an image of the surface of the sheet after the decoloring unit performs the decoloring processing on the sheet. The processor determines a color of the sheet based on the generated image. The processor determines one sheet stacking tray out of the plurality of sheet stacking trays as a transport destination of the sheet, based on the determined color. The transporting unit transports the sheet to the determined sheet stacking tray.
Claims17
A sheet sorting device comprising:
- a transporting unit configured to transport a sheet;
- a reading unit configured to generate an image of a surface of the sheet;
- a decoloring unit configured to perform a decoloring processing to decolor an image on the sheet;
- a plurality of sheet stacking trays;
- and
- a processor configured to:
- cause the reading unit to generate an image of the surface of the sheet after the decoloring unit performs the decoloring processing on the sheet,
- determine a color of the sheet based on the generated image,
- determine one sheet stacking tray out of the plurality of sheet stacking trays as a transport destination of the sheet, based on the determined color, and
- control the transporting unit to transport the sheet to the determined sheet stacking tray.
A non-transitory computer readable medium containing instructions causing a sheet processing device that includes a reading unit configured to generate an image of a surface of the sheet and a plurality of sheet stacking trays to perform a sheet sorting method comprising the steps of:
- determining a color of the sheet based on the image generated by the reading unit,
- determining one sheet stacking tray out of the plurality of sheet stacking trays as a transport destination of the sheet, based on the determined color, and
- transporting the sheet to the determined sheet stacking tray.
A decoloring device comprising:
- a transporting unit configured to transport a sheet;
- a reading unit configured to generate an image of a surface of the sheet;
- a decoloring unit configured to perform a decoloring processing to decolor an image on the sheet;
- and
- a processor configured to:
- control the reading unit to generate a first image of the surface of the sheet before the decoloring unit performs the decoloring process on the sheet,
- control the decoloring unit to perform the decoloring processing on the sheet,
- generate a second image of the surface of the sheet after the decoloring unit performs the decoloring process on the sheet,
- determine a color of the sheet based on at least one of the first image and the second image,
- determine whether the sheet is reusable based on the first image compared to the second image,
- generate data that includes, in association, an identification of the sheet, the determined color of the sheet, and whether the sheet is determined to be reusable, and
- output the generated data to a separate sorting device.
