Paper sheet taking-out and separating device and paper sheet handling apparatus

Abstract

A paper sheet taking-out and separating device according to an embodiment includes a first take-out part, a guide part, a second take-out part and a separation part. The first take-out part takes, by suction, a forefront paper sheet out of a plurality of stacked paper sheets and sends out the paper sheet toward a sending-out direction. The guide part guides the sending out of the paper sheet by the first take-out part. The second take-out part sucks the paper sheet sent out by the first take-out part and sends out the paper sheet toward the sending-out direction. The separation part separates a plurality of the paper sheets sent out in an overlapping manner by the first take-out part. The first take-out part and the second take-out part are positioned spaced apart from each other on opposite sides of the guide part with a predetermined distance therebetween in the sending-out direction.

What is claimed is: 
     
         1 . A paper sheet taking-out and separating device comprising:
 a first take-out part taking out, by suction, a forefront paper sheet out of a plurality of stacked paper sheets and sending out the paper sheet toward a sending-out direction;   a guide part provided on a downstream side of the first take-out part in the sending-out direction, the guide part guiding the sending out of the paper sheet by the first take-out part;   a second take-out part provided on the downstream side of the guide part in the sending-out direction, the second take-out part sucking the paper sheet sent out by the first take-out part and sending out the paper sheet toward the sending-out direction; and   a separation part provided on the downstream side of the guide part in the sending-out direction, the separation part separating a plurality of the paper sheets sent out in an overlapping manner by the first take-out part, wherein   the first take-out part and the second take-out part are positioned spaced apart from each other on opposite sides of the guide part with a predetermined distance therebetween in the sending-out direction.   
     
     
         2 . The paper sheet taking-out and separating device according to  claim 1 , wherein an end of the second take-out part on an upstream side in the sending-out direction is positioned on the upstream side of the separation part in the sending-out direction. 
     
     
         3 . The paper sheet taking-out and separating device according to  claim 1  or  2 , wherein the first take-out part and the second take-out part are turned into an on state which enables suction of the paper sheet substantially at the same time. 
     
     
         4 . The paper sheet taking-out and separating device according to  claim 3 , further comprising a conveyance mechanism positioned on the downstream side of the separation part in the sending-out direction, the conveyance mechanism conveying the paper sheet sent out by the second take-out part toward a conveyance direction, wherein
 the first take-out part and the second take-out part are switched from the on state to an off state which disables the suction of the paper sheet substantially at a same time when a front end, in the sending-out direction, of the paper sheet which has been sent out by the second take-out part reaches a front of the conveyance mechanism.   
     
     
         5 . The paper sheet taking-out and separating device according to  claim 4 , wherein the first take-out part and the second take-out part are switched from the off state to the on state substantially at a same time when any two of the paper sheets adjacent one behind the other in the sending-out direction between the guide part and the conveyance mechanism have an interval equal to or larger than a predetermined value therebetween. 
     
     
         6 . The paper sheet taking-out and separating device according to  claim 4 , further comprising a sensor which detects passage of the paper sheet through a predetermined point between the guide part and the conveyance mechanism in the sending-out direction, wherein
 the first take-out part and the second take-out part are turned into one of the on state and the off state corresponding to the passage of the papers sheet detected by the sensor.   
     
     
         7 . The paper sheet taking-out and separating device according to any one of  claims 1 , wherein the first take-out part and the second take-out part are connected to a single chamber to which a negative pressure is applied by a pressure pump. 
     
     
         8 . A paper sheet handling apparatus comprising:
 a first take-out part taking out, by suction, a forefront paper sheet out of a plurality of stacked paper sheets and sending out the paper sheet toward a sending-out direction;   a guide part provided on a downstream side of the first take-out part in the sending-out direction, the guide part guiding the sending out of the paper sheet by the first take-out part;   a second take-out part provided on the downstream side of the guide part in the sending-out direction, the second take-out part sucking the paper sheet sent out by the first take-out part and sending out the paper sheet toward the sending-out direction;   a separation part provided on the downstream side of the guide part in the sending-out direction, the separation part separating a plurality of the paper sheets sent out in an overlapping manner by the first take-out part; and   a classification unit provided on the downstream side of the separation part in the sending-out direction, the classification unit classifying the paper sheet.
