Abstract

PURPOSE: To provide a paper-sheet attracting and separating apparatus, which is capable of minimizing occurrence of the so-called "misfeed" phenomenon that paper sheet can not be attracted and separated from the stack by means of sucker and another phenomenon that more than two paper sheets are attracted at a time.
CONSTITUTION: The paper-sheet attracting and separating arraratus shown in the drawing comprises a vacuum pump 11, a sucker 3 connected to the suction side of said vacuum pump 11 and arranged to be capable of swinging with respect to paper sheets 1 for attracting and separating one sheet after another from the stack, a nozzle 13 for blowing air supplied from the outlet side of pump 11 onto the side face of paper sheet 1, and a swing valve 12 provided in a conduit 14 for connecting the pump 11 and sucker 3 so as to establish or interrupt communication between sucker 3 and the suction side of pump 11 along with swinging of sucker 3. Further, a throttle valve 19 is provided at suction port 3a of sucker 3, so as to prevent that vacuum in the region between the suction side of pump 11 and sucker 3 may not be reduced to zero before starting operation of sucker 3 and also to supply a sufficient amount of air necessary for separating the paper sheet from the stack.
