Claim:
A device for removing adhered substances from a long wiping sheet wounded into a roll after the wiping sheet is used for wiping off the adhere substances, comprising: an upstream roller configured to rotatably support the wiping sheet wounded into the roll; a downstream roller configured to rewind the wiping sheet drawn from the upstream roller into a roll while delivering the wiping sheet to a downstream side in a delivery direction of the wiping sheet; a liquid supply unit arranged between the upstream and downstream rollers and configured to supply a liquid medium to the wiping sheet as an oscillation transmission medium; a storage tank configured to store the liquid medium supplied from the liquid supply unit; an oscillation unit arranged above the storage tank and including an ultrasonic oscillator providing oscillation to the liquid medium with which the wiping sheet is impregnated; and a suction removal unit arranged downstream the oscillation unit and configured to suck and remove the liquid medium with which the wiping sheet is impregnated and the adhered substances separated from the wiping sheet by the oscillation unit and re-adhered to a surface of the wiping sheet, wherein the suction removal unit includes a cylindrical suction nozzle extending in a width direction of the wiping sheet and having an inlet hole in a surface along which the wiping sheet is guided, a lid detachably attached so as to close an opening at least one end of the suction nozzle, and a suction pump configured to suck air from the suction nozzle.
