One to do A holding unit 130, and a dispensing holding unit 135 for discharging the bills as change to the outside of the apparatus, the control means 140 for controlling them, and.

The transport mechanism 110 sorts and transports the banknotes fed one by one from the deposit taking-in part 104 to the first or second banknote storage device 120 or 125 by denomination by transporting the banknotes by a predetermined route. And the function of sequentially transporting and stacking the banknotes fed out one by one from the first or second banknote storage device 120, 125 into the temporary storage unit 130, and the banknotes fed out from the temporary storage unit 130 And a collective conveyance function that collectively feeds the bundle to the second bill storage device 125 that also serves as a collection storage device via the conveyance path 105.
The 2nd banknote storage apparatus 125 is comprised so that attachment or detachment is possible in a cassette type, and it is comprised so that the 2nd banknote storage apparatus 125 can be taken out and the stored banknote can be collect | recovered.
In banknote collection work at the end of work, an operator operates a predetermined collection switch to send 10,000 yen banknotes in the first banknote storage device 120 one by one to the transport path 105 and perform high speed by the transport mechanism 110. After stacking a predetermined number of sheets (for example, 15 sheets) on the temporary storage unit 130 by transporting, the operation of collectively transporting 15 ten thousand yen banknote bundles in the temporary storage unit into the second banknote storage device 125 is performed. By repeating, all the 10,000 yen banknotes accommodated in the first banknote storage device 120 are transferred to the second banknote storage device 125.
The second banknote storage device 125 is also used as a collected banknote storage unit, and collects all the first and second banknotes in the second banknote storage device 125 at the end of work, thereby performing a collective collection operation. It becomes possible.

Next, FIGS. 5A and 5B are a front view and a main part perspective view showing a specific configuration of the banknote feeding mechanism equipped in the reflux type second banknote storage device.
The bill feeding mechanism 150 is freely rotatable by a pull roller 152 as a driving side roller rotatably supported by a central shaft 152a and a bracket 155 supported by a fixed shaft 155a parallel to the central shaft 152a of the pull roller 152. A pressure roller 156 as a driven roller that is pivotally supported by the roller and advances and retreats with respect to the circumferential surface of the pull roller, and conveys paper sheets in the introduction direction and the discharge direction at the nip portions of both rollers 152 and 156. The banknotes are discharged from the banknote stacking unit 126 located on the downstream side to the transport path while allowing the group 151 and the sheets (bundles) transported in the introduction direction by the first roller group 151 to pass. In this case, a second roller group 160 including a friction roller 161 functioning as a separation roller for preventing double feeding and a stop roller 162, and a bra One end is supported by the buckling prevention guide member 165 that is integrated with the base plate 155 and pivotally supported by the fixed shaft 155a, and the housing 127 (fixed portion) of the second banknote storage device 125. And an elastic member 170 that constantly abuts the bracket 155 to urge the bracket 155 and the buckling prevention guide member 165 in one direction.

The banknotes (bundles) that have passed through the first and second roller groups are stacked on a banknote stacking table (not shown) in the banknote stacking section 126 located on the downstream side. When discharging one sheet at a time from the uppermost surface of the banknote bundle on the stacking table, a conveying roller (not shown) rotates in the discharging direction and transfers to the nip portion of the friction roller 161 and the stop roller 162. The friction roller 161 and the stop roller 162 separate the bills to be fed, and convey only one sheet in the discharge direction.
Since the bracket 155 and the buckling prevention guide member 165 are normally biased in one direction A by the elastic member 170, the pressure roller 156 is pressed against the peripheral surface of the pull roller 152, and at this time, the fixed shaft 155a. The buckling prevention piece 166 of the buckling prevention guide member 165 arranged on the opposite side via the gap is set so that the distance between the lower edge and the conveyance guide has a predetermined dimension. In order to prevent the banknotes from being bent when they are discharged one by one from the uppermost part of the banknote stack stacked on the banknote stacking unit in the second banknote storage device 125 to the transport path, It is preferable to regulate the gap between the edge and the banknote discharge line (the upper surface of the banknote to be discharged), that is, the distance from the conveyance guide to be appropriately narrow.

When the banknote bundle is introduced into the nip portion of the first roller group 151 from the conveyance path, the pressure roller 156 rotates in the direction B away from the pull roller 152 against the elastic member 170, so that the bracket 155 The buckling prevention piece 166 of the integrated buckling prevention guide member rotates in the B direction opposite to the arrow A. That is, when the banknote bundle is introduced, the buckling prevention piece 166 rotates in the direction of narrowing the introduction path of the banknote bundle, interferes with the introduced banknote bundle and becomes resistance to the banknote bundle passage, and the smooth passage of the banknote bundle is hindered. The In order to deal with such problems, even when banknotes are discharged one by one from the banknote stack on the banknote stacking table, an unnecessary gap is secured between the lower edge of the buckling prevention piece 166 and the banknote discharge line. It is necessary to keep it. For this reason, there exists a possibility that the buckling prevention effect may fall.
Moreover, since it was necessary to support the end of the elastic member 170 with the housing | casing 127 of the 2nd banknote storage apparatus 125, this was the restriction | limiting on a layout.
Such a problem can also occur in a paper sheet handling apparatus that handles paper sheets other than banknotes.

In this case, since the buckling prevention guide member and the bracket were integrated and elastically biased in one direction, the pressure roller is greatly separated from the pull roller when the thick banknote bundle is introduced. There was a possibility that the prevention guide member would interfere too much with the banknote discharge line. On the other hand, if the gap between the two is ensured so that the buckling prevention guide member does not interfere too much with the banknote discharge line, the banknote discharge line along the nip portion of the separating roller pair Contrary to the request that the gap with the buckling prevention guide member should be as narrow as possible, there arises a problem of a contradiction in that the buckling prevention effect is reduced.
The present invention has been made in view of the above.

Since the buckling prevention guide member interferes with the paper sheet discharge line in conjunction with the bracket that supports the pressure roller, it has become a resistance to the paper sheet bundle to be introduced, making smooth introduction difficult. . In order to deal with such a problem, if the interval between the buckling prevention guide member and the paper sheet discharge line is set excessively, the discharged banknotes are separated by the separation roller pair constituting the second roller group. The effect of preventing buckling is reduced. In the present invention, the bracket for supporting the pressure roller and the buckling prevention guide member are configured to operate independently and attached in the expanding direction by an elastic member disposed between the bracket and the buckling prevention guide member.

An identification device 15 for determining the authenticity and denomination of bills that are arranged and fed one by one, and connected to the bill transport path 5 to accommodate the first bill related to the first denomination in a freely retractable manner. Switchback recirculation type first banknote storage device 20 and switchback recirculation type second banknote connected to the banknote transport path 5 to accommodate the second banknote relating to the second denomination in a freely retractable manner It is conveyed via the storage device 25 and the conveyance path 5. A temporary storage unit (banknote storage device) 30 for receiving and stacking the banknotes received one by one and discharging the stacked banknote bundle at once, a withdrawal storage unit 35 for discharging banknotes as change to the outside of the device, and these And control means 36 for controlling.
The deposit taking-in unit 4 is provided with a separating and feeding mechanism for feeding a plurality of bills that have been batch-loaded into the transport path 5 while separating them one by one.

The transport mechanism 10 sorts and transports the banknotes fed one by one from the deposit taking-in unit 4 to the first or second banknote storage device 20 or 25 by denomination by transporting the banknotes by a predetermined route. A banknote that has been fed from the first or second banknote storage device 20, 25 one by one and that is sequentially transported and stacked in the temporary storage section 30, and a banknote that has been paid out from the temporary storage section 30 And a collective conveyance function that collectively feeds the bundle to the second banknote storage device 25 that also serves as a collection storage device via the conveyance path 5. By driving each roller, belt, and gate 11 under the control of the control means 36, the above-described transport functions can be realized at a predetermined timing.
The first banknote storage device 20 is dedicated to the first banknote, for example, a 10,000 yen banknote, and has a reflux function for sending 10,000 yen banknotes once received via the transport path 5 to the transport path 5 one by one. Have.
The second banknote storage device 25 is dedicated to a second banknote that is frequently used as change, for example, a thousand-yen banknote, and sends the thousand-yen banknote once received via the transport path 5 to the transport path 5 one by one. It has a switchback type reflux function.
The temporary storage unit (banknote storage device) 30 receives the banknotes fed out one by one from the first or second banknote storage devices 20 and 25 and stacks a predetermined allowable number of banknotes, It has a batch delivery function that feeds the stacked banknote bundles to the transport path.

In the present embodiment, for example, the second banknote storage device 25 is configured to be detachable in a cassette type (including free access), and is provided on the wall portion of the exterior body 3 that faces the second banknote storage device 25. The second banknote storage device 25 is taken out by opening the door that is not to be used, and the stored banknotes can be collected.
In the banknote collection operation at the end of work, when the operator operates a predetermined collection switch, the control means 36 performs the following control. That is, 10,000 yen banknotes in the first banknote storage device 20 are sent one by one to the transport path 5 and transported at a high speed by the transport mechanism 10 so that a predetermined number (for example, 15 sheets) is stacked on the temporary storage unit 30. After that, by repeating the operation of batch transporting 15 ten thousand yen banknote bundles in the temporary storage unit into the second banknote storage device 25, all the ones stored in the first banknote storage device 20 are stored. The 10,000 yen bill is transferred to the second bill storage device 25. The number of banknotes sent to the temporary storage unit 30 is counted based on passage information detected by a paper passing sensor disposed at an appropriate position such as a conveyance path.

In this embodiment, the second banknote storage device 25 is also used as a collected banknote storage device, and collects all the first and second banknotes in the second banknote storage device 25 at the end of work.

Of course, the second bill storage device 25 that accommodates a thousand-yen bill that is frequently used as a bill used as a change as well as a bill inserted by a user is also used as a bill collection storage device. By adopting a configuration in which bills with low usage frequency such as yen bills are transferred to the second bill storage device 25, the recovery time can be shortened.
The temporary storage unit (banknote storage device) 30 has a configuration for stacking banknotes conveyed at high speed one by one in a stacked state, and sending the stacked banknote bundle to the transport path 5 in a lump. The collected banknote bundle is fed into the second banknote storage device 25 all at once, so that the collection efficiency can be greatly increased. That is, since 10,000 yen banknotes in the first banknote storage apparatus with a small number of stored sheets are stacked and accumulated in the temporary storage unit 30 and then transferred together as a banknote bundle into the second banknote storage apparatus, It is clear that the collection time is significantly shortened as compared with the conventional apparatus that transfers the sheets one by one. And since the exclusive collection | recovery banknote storage apparatus is not necessarily provided separately, the whole size of an apparatus can be made small.

Next, FIGS. 2A and 2B are a perspective view and a front view showing the configuration of the paper sheet feeding mechanism according to one embodiment of the present invention, and FIGS. It is the front view and top view which show the structure description of a buckling prevention guide member.
The paper sheet feeding mechanism 40 includes a pull roller 42 rotatably supported by a central shaft 42a, a bracket 43 pivotally supported by a fixed shaft 44 parallel to the central shaft 42a of the pull roller, and the bracket 43 And a pressure roller 45 that is rotatably supported by the roller and advances and retreats with respect to the peripheral surface of the pull roller 42, and nips banknotes (paper sheets) between the rollers 42 and 45 and conveys them in both forward and reverse directions. While one roller group 41 and one sheet of paper or a bundle of sheets conveyed in the introduction direction by the first roller group 41 are allowed to pass, they are allowed to pass while being discharged. The second roller group 50 composed of the friction roller 51 and the stop roller 52 exhibiting the separating function, the paper sheet stacking portion 26 disposed on the downstream side in the introduction direction of the second roller group 50, and the bracket 43 are Relative rotation possible In this state, a buckling prevention piece 61 that is pivotally supported on the upstream side in the introduction direction by the fixed shaft 44 and prevents buckling of the paper sheets discharged from the paper sheet stacking portion 26 is provided downstream in the introduction direction. The buckling prevention guide member 60 is disposed between the bracket 43 and the buckling prevention guide member 60 and urges the bracket 43 in a direction to press-contact the peripheral surface of the pull roller 42. And a single elastic member 70 for urging the lower edge toward the upper surface of the conveyance guide.
The fixed shaft 44 is a fixed shaft that does not move. The central shaft 42a of the pull roller 42 and the shaft 52a of the stop roller 52 are also fixed shafts that do not move.

The bracket 43 includes a pair of roller support portions 43b that are inserted in the shaft hole 43a so as to be pivotable in the vertical direction through the fixed shaft 44 and project in front of the shaft hole 43a. The pressure roller 45 is rotatably supported by a shaft 45a that is supported between 43b. A part of the bracket 43 is provided with a spring receiving portion 43 c that fixes one end of the elastic member 70.
The buckling prevention guide member 60 includes a shaft hole 60a that is pivotally supported by the outer sides of the fixed shaft 44 that supports the bracket 43 by an intermediate portion so as to be rotatable in the vertical direction, and a pair of protrusions that protrude rearward from the shaft hole 60a. One end is supported by a buckling prevention piece 61, a connecting piece 62 provided continuously between the upper portions of each buckling prevention piece 61, and a spring receiving portion 43 c provided on the bracket 43 so as to protrude from the connecting piece 62. And a spring receiving portion 63 that supports the other end of the elastic member.
Above the buckling prevention piece 61, a protruding piece 65 is provided at a predetermined interval and is arranged in a U-shape with the buckling prevention piece 61. Between the buckling prevention piece 61 and the protruding piece 65, a regulating member 66 fixed to the housing side is located, and the regulating member 66 regulates the range in which the buckling preventing guide member 60 can move up and down. It is configured.

At normal times, the protruding piece 65 and the regulating member 66 abut against each other by the urging force of the elastic member 70 and the rotation is regulated. At this time, the interval between the lower edge of the buckling preventing piece 61 and the conveyance guide is appropriate. It is set to be narrow.
The friction roller 51 having a high friction portion on the outer peripheral surface is driven in the clockwise direction when the bills are conveyed one by one in the discharge direction (from the right to the left). The friction roller 51 is configured to be movable up and down with respect to the circumferential surface of the stop roller 52 by being supported by a support member (not shown) so as to move up and down, and the banknote bundle is introduced in the direction of introduction (from left to right). When it is conveyed, it is retracted upward to allow passage. The stop roller 52 normally rotates in a clockwise direction with a small torque. When the paper sheet is introduced, the stop roller 52 rotates clockwise to allow the paper sheet to be introduced. It functions to return the lower banknote to the banknote stacking unit 26 side. Specifically, the stop roller 52 has a configuration in which an outer roller member 52b is supported by a shaft member 52a that is rotationally driven, and a one-way clutch (not shown) is disposed between the shaft member 52a and the roller member 52b. Yes. The rotational driving force in the clockwise direction from the shaft member 52a is transmitted to the roller member 52b via the one-way clutch, and rotates the roller member 52b in the same direction. For this reason, the lower banknote of the multi-feed banknotes discharged from the banknote stacking section is returned to the banknote stacking section by the roller member 52b. When a bill is introduced from the transport path, the roller member 52b rotates clockwise and does not hinder the introduction of the bill.

  In the present invention, the bracket 43 is a member that is supported by the fixed shaft 44 so as to be movable up and down and supports the pressure roller, and the buckling prevention guide member 60 that is pivotally supported by the common swing shaft 44 so as to be movable up and down. And the elastic member 70 disposed between the bracket 43 and the buckling prevention guide member 60 is configured to urge the bracket and the buckling prevention guide member in the opposite directions, thereby supporting the elastic member. This eliminates the need for support by the fixing part on the second banknote storage device 25 side, thereby reducing layout restrictions. Further, even when the banknote bundle passes between the pull roller 42 and the pressure roller 45 and the pressure roller 45 moves upward against the elastic member 70, the buckling prevention guide member 60 moves up and down in conjunction with it. It does not move, and the distance between the lower edge of the buckling prevention piece 61 and the banknote discharge line does not approach more than necessary. That is, when the introduced banknote bundle passes between the rollers 51 and 52, the buckling prevention guide member 60 can retreat (rotate) upward against the elastic member, while the discharged banknote However, when passing between the rollers 51 and 52, the buckling prevention piece 61 can be held in an optimum position and guided while preventing the banknote from buckling.

As described above, in the present invention, the bracket 43 that supports the pressure roller 45 and the buckling prevention guide member 60 are configured to operate independently (relatively rotate), and the bracket and the buckling prevention. By applying an urging force in the expanding direction by the elastic member 70 arranged between the guide members, each trouble at the time of introducing the paper sheet bundle and discharging the banknote (interference to the banknote discharge line by the buckling prevention guide member) , Reduction of the buckling prevention function for preventing it) can be solved at once. Further, since it is not necessary to support the elastic member on the fixing portion on the apparatus main body side, the degree of freedom in layout can be increased.
The present invention can be applied to a reflux paper sheet processing apparatus that processes not only banknotes but also other paper sheets. Moreover, this reflux type paper sheet processing apparatus can be applied to banknote handling apparatuses such as various vending machines, deposit / withdrawal apparatuses, and money changers.
