Paper separating device and paper separating method

Abstract

A sheet separation device (11) comprising: a separation roller (16) in contact with paper conveyed from an accumulation unit that accumulates the paper; a feed roller (17) arranged in contact with the separation roller (16) and Rotate relative to the stopped separation roller (16) to convey the sheets separately one by one; and a pair of guide members (18) which have guide surfaces (18a) and are arranged in the axial direction of the separation roller (16) On both sides in the direction, the guide surface is in sliding contact with the leading end of the paper conveyed from the accumulation unit. The friction coefficient of the guide surface (18a) is smaller than the friction coefficient of the outer peripheral surface (16a) of the separation roller (16). The guide surface (18a) is provided to protrude from the outer peripheral surface (16a) of the separation roller (16) to the outside of the separation roller (16) in the radial direction of the separation roller (16), and the guide surface (18a) is supported to The point of contact between the separation roller (16) and the feed roller (17) is movable toward the inner side of the separation roller (16) in the radial direction.

Description

technical field [0001] The invention relates to a paper separating device and a paper separating method. Background technique [0002] As a bill handling apparatus such as an ATM (Automatic Teller Machine), there is known a bill handling apparatus including a bill storage device for temporarily storing deposited bills. Such banknote storage devices include a banknote separating device for separating and feeding the accumulated banknotes one by one after the banknotes are stored in the accumulation unit. [0003] The banknote separating device is configured with a set of separating rollers and feeding rollers for separating and feeding the banknotes accumulated in the accumulation unit one by one. In the banknote separation device, the front end of the banknote advancing from the accumulation unit side is in contact with the outer peripheral surface of the separation roller at the contact point between the separation roller and the feed roller to reduce overlapping of bankno...

AI Technical Summary

Problems solved by technology

However, in the banknote separation device, the front end of the banknote advancing from the accumulation unit side may come into contact with the outer peripheral surface of the separation roller at a position away from the above-mentioned contact point toward the accumulation unit side.

In this case, since the separation roller used is made of rubber, the frictional force between the banknote and the outer peripheral surface of the separation roller largely acts on the front end of the banknote and may restrict the advance of the banknote

As a result, the banknotes are drawn in a state of abnormal deformation between the separation roller and the feed roller, and paper jams (hereinafter referred to as jams) are disadvantageously caused

[0004] In addition, in the banknote separating device, when the front end of the banknote comes into contact with the corner portion (edge) on the end face side of both ends in the axial direction of the separation roller, the banknote may stop due to the frictional force between the front end and the edge, causing Skew (notes are fed obliquely in the correct feeding direction of the notes)

As a result, skewed banknotes are drawn between the separation roller and the feed roller, and jamming is disadvantageously caused
