Abstract

PURPOSE:To reliably separate and take out a soft sheet lacking firmness by providing feed-in means comprising a pair of eccentric rotating members, one of which is positioned adjacent to take-out means and an endless body having a high friction member on the surface thereof, which is stretched between the above members. CONSTITUTION:The lowermost sheet P1 of sheets P is brought into contact with a take-out roller 56 and an endless belt 58 stretched between feed-in pulleys 57A, 57B, and high friction members 56b and 58b operating at the substantially same speed are brought into rolling contact with the sheet P to be fed into a gap C'. At this time, as the gap C' is set corresponding to a thickness (t) of the sheet P, the second and following sheets can be separated from the sheet P1 by a separation roller 59. Accordingly, only the lowermost sheet P1 is transported through the gap C' to the interior of an apparatus by a pair of pick-up rollers 61. Thus, the sheets P can be reliably separated sheet by sheet to be taken out in direction of an arrow G' even if the sheets lack firmness and are soft.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is applied to a paper sheet processing device such as a single banknote counting machine, and is applicable to a paper sheet processing device that sequentially takes out paper sheets such as banknotes one by one. This invention relates to improvement of a take-out device.

[Technical background of the invention and its problems]

A number of paper sheet processing devices such as single banknote counters have been put into practical use, but in recent years, only popular machines have been used to take out single paper sheets due to the simple mechanism, low price, small space, etc. The friction extraction method is becoming mainstream even in high-end machines.

Therefore, improvements in friction capture systems have been remarkable.

As one of the conventional paper sheet retrieval devices of this type.

There are those shown in FIGS. 8 to 10. In the figure, a is paper sheet P.
This is a receiving part that receives the stacked materials, and this receiving part a
consists of a bottom plate, a front guide C, a surface guide d (right surface guide e, left surface guide 'f), and a pressing plate g.

On the upper and lower sides of the bottom plate, there are provided a take-out roller 2) which is pivoted on the shaft, and a feed roller k which is eccentrically attached to the shaft and rotates in the directions of arrows A and B, respectively. It is designed to rotate in sync with the Further, a high-friction member l is fixed to a part of the outer peripheral surface of the take-out roller i, and a high-friction member m is also fixed to the outer surface of the feed roller. The bottom plate has notches (not shown) corresponding to the positions of the take-out roller 1 and the feed roller to the top of the bottom plate. On the upper part of the intake roller 1, there is a gantry fC, and a gantry fC is placed on the upper side of the separator roller O, which is attached to the shaft n.
A high friction member p is also fixed to the outer surface of the separation row 20. Further, the separation roller 0 is supported movably in the direction in which the gap C becomes larger by a support mechanism (not shown), and is further applied with an appropriate pressing force by a suppression mechanism (not shown) to hold the gap C in the direction of the arrow. is recieving.

The suppression plate g is mounted on a shaft r via a bearing q, is movable in the direction of arrow E, and is further applied with an appropriate pressing force in the direction of arrow F by a suppression mechanism (not shown). Is receiving. As a result, the lowest paper sheet P of the paper sheets P,
, a high friction member of 1 mm fixed to the take-out roller i and the feed roller k, which rotate synchronously, rolls into contact with the paper sheets P and feeds them into the gap C. Includes 1. At this time, the second and subsequent paper sheets Pi(i
=2°3, . . . ) is separated from the paper sheet P1 by the separation roller O because the gap fC is set corresponding to the thickness t of the paper sheet. Therefore, only the lowest sheet P passes through the gap C and is conveyed to the inside of the paper feeder by two pick-up rollers (not shown). As described above, the lf& and X type PViI sheets are separated into traps and taken out in the direction of arrow G.

However, when one sheet @P is a so-called limp and twisted sheet, the lowest sheet P1 buckles between the take-in roller i and the feed roller, as shown in Fig. 10. Sisters,
Occurrence of skip phenomenon [a phenomenon that causes ejection errors on a -11h basis].

Not only does the paper sheet P0 need to be folded in two to be taken out, but it often becomes impossible to take it out. If we consider the conventional friction extraction methods, most of them are
#rRemoval means as described in J.

It is composed of a feeding means and a separating means, and when separating and taking out the so-called loose and curly paper sheets one by one, the adhesion between each sheet is good, so the apparent paper Because the coefficient of friction between the leaves is not high, all the sheets are sent by the feeding means to the unloading means and the separating means. Because of the stiffness and twisting, the feeding performance of the feeding means is not sufficient, and the paper sheet cannot be fed by the take-out means and the separating means 1, and the paper sheets cannot be fed by the above-mentioned feeding means.

There was a problem in that the paper sheets were buckled between the take-out means and the separation means.

Therefore, in order to compensate for this, some machines have limited the specifications of the paper sheets that can be handled, so that they do not handle loose and crooked paper sheets. However, in many cases, it is not possible to limit the conditions as described above, and in particular, in a banknote processing apparatus such as a banknote counting machine, it is difficult to limit the state of banknotes handled, and this is not beneficial to the user. In view of the above, it is desired to realize a paper sheet retrieval method that can accurately take out so-called limp and tangled sheets.

[Purpose of the invention]

The present invention has been made based on the above-mentioned circumstances, and its purpose is to improve the so-called limp and weak body.
To provide a paper sheet take-out device which can reliably separate and take out even paper sheets one by one.

[Summary of the invention]

In order to achieve such an object, the present invention allows a plurality of paper sheets received in a stacked state in a receiving section to be pushed in a predetermined direction by a feeding means, and the fed paper sheets are taken out by a take-out means. This is a paper sheet take-out device in which the paper sheets gJ4 which are taken out at the same time are separated one by one by a separating means.

The feeding means 'fI: at least a pair of eccentric rotating members, one of which is located near the ejecting means, and a cylindrical friction member '! which is spanned between these eccentric rotating members and is provided on its outer surface. The paper sheet has a structure having an endless strip body with an endless strip, and can be fed into the take-out means while having a large contact area with the paper sheet to prevent buckling of the paper sheet.
