Summary of Invention

Technical Problem

[0004] Some of the inserting sections of those paper sheet processing devices comprise a bill press for horizontally pressing the stacked paper sheets. As shown in Fig. 10, the paper sheets might be banknotes S formed with fine protrusions B for identifying types by touching them with fingers and for preventing counterfeiting. When such banknotes S are stacked in the inserting section, portions at which the protrusions B overlap become higher than the other portions, which causes uneven abutment in which the bill press only abuts the overlapping portions of the protrusions B of the banknotes S so that there was a risk that the banknotes S could not be accurately pressed and smoothly sent into the machine body.

[0005] Accordingly, the present invention provides a paper sheet feeding device that can smoothly send paper sheets into the machine body.

Solution to Problem

[0006] For achieving the above subject, the paper sheet processing device according to the present invention is a paper sheet feeding device that presses paper sheets placed in an intake section towards a feed roller by means of a bill press and takes the paper sheets in into a machine body, wherein the bill press comprises a main pressing section that is provided to be movable up and down in the intake section and can press the substantial center of the paper sheets, and auxiliary pressing sections that are provided independently of the main pressing section and can press regions of the paper sheets other than the substantial center.

[0007] According to this configuration, even if there are height variations in the paper sheets stacked in the intake section in which portions of the paper sheets at which protrusions overlap become locally higher, the main pressing section presses the substantial center of the paper sheets while the auxiliary pressing sections can press the paper sheets in a swinging state in accordance with heights of the paper sheets, which restricts uneven abutment in which the bill press only abuts a part of the paper sheets so that the paper sheets are stably pressed towards the feed roller over a wide range and the paper sheets can be smoothly sent into the machine body.

Advantageous Effect of Invention

[0008] According to the present invention, paper sheets are stably pressed towards the feed roller over a wide range so that the paper sheets can be smoothly sent into the machine body.

It should be noted that, hereinafter, when reference is made to numbers, numerical values, amounts, ranges, or the like of components, it does not mean that those particular numbers are restrictive, and they might be greater or less than those particular numbers unless specifically indicated or they are theoretically clearly limited to particular numbers.

[0011] Further, when reference is made to shapes or positional relationships of components or the like, it shall include shapes or the like that substantially approximate or resemble unless specifically indicated or that can be theoretically considered apparently not to be.

[0012] Further, drawings might exaggerate, by for instance, enlarging characteristic portions for ease of understanding features, and dimensional proportions or the like of the components are not necessarily identical to those in reality.

<Structure of the Banknote Processing Device>

[0013] As shown in Fig. 1, the banknote processing device 1 comprises a base machine 2 and a connecting unit 3. The connecting unit 3 is configured by selecting at least of the number and type of units that respectively have different functions and by combining them with the base machine 2 in an appropriate order.

<Configuration of the Base Machine>

[0014] The base machine 2 identifies and counts a banknotes S inserted from outside by an operator. The base machine 2 comprises an intake section 5 on a righthand surface 4a of a machine body 4 when seen from the operator of the banknote processing device 1.

[0015] The banknotes S are inserted into the intake section 5 from outside by an operator. The intake section 5 comprises a bottom surface section 6 onto which the banknotes S are placed, and a back wall surface section 7 provided upward of a left end of the bottom surface section 6 in the left-right direction. The bottom surface section 6 and the back wall surface section 7 are formed to be substantially in a plane in the front-back direction.

[0016] The banknotes S are vertically stacked and placed on the bottom surface section 6 with their short sides extending along the left-right direction and their long sides along the front-back direction (direction perpendicular to the image plane of Fig. 1). Further, the bottom surface section 6 is inclined downward to the left with respect to the horizontal plane when seen from the front of the machine body 4, and the banknotes S stacked on the bottom surface section 6 abut with each of their long sides against the back wall surface section 7 along the inclination of the bottom surface section 6 and are collected on one side so that positions in the short direction are aligned.

[0017] An intake port 8 that pierces through the back wall surface section 7 in the thickness direction is provided in the vicinity of the bottom surface section 6. The length of the intake section 8 in the front-back direction is set to be longer than the long sides of the banknotes S.

[0018] The intake section 5 comprises a feed roller 9 provided at the bottom surface section 6, an intake roller 10 provided in vicinity of the intake port 8, a separating roller 11 provided to oppose the intake roller 10, and a detecting section 12 for sensing taken-in banknotes S and for detecting taking-in states.

[0019] The feed roller 9 is provided on a lower side of the bottom surface section 6 and partially projects upward from the bottom surface section 6. The feed roller 9 separates each of the banknotes S stacked on the bottom surface section 6 one by one from the lowermost layer and sends them into the interior of the machine body 4 upon passing the intake port 8. The intake roller 10 takes in the banknotes S kicked out from the feed roller 9 and delivers them to an identifying and conveying section 13. The separating roller 11 separates the banknotes S taken in by the intake roller 10 one by one. The banknotes S are moved such that their short sides extend along the conveying direction, fed out to the left of the machine body 4, and are moved in the banknote processing device 1 while maintaining a posture with their long sides extending along the front-back direction.

[0020] The intake section 5 comprises a bill press 100 that is vertically movable along the back wall surface section 7. The bill press 100 presses the banknotes S stacked on the bottom surface section 6 towards the feed roller 9 from above. Accordingly, in the intake section 5, the banknote S of the lowermost layer from among the stacked banknotes S sticks to the feed roller 9 and is kicked out smoothly.

[0021] The base machine 2 comprises the identifying and conveying section 13 that receives and conveys the banknotes S fed out from the intake section 5, and an identifying section 14 that identifies the banknotes S that are being conveyed by the identifying and conveying section 13. The identifying and conveying section 13 extends horizontally from the intake section 5 towards the left side in the left-right direction and then extends upward in the vertical direction. The identifying section 14 is provided at a portion that extends upward of the identifying and conveying section 13.

[0022]  The base machine 2 comprises a connecting and conveying section 15 that extends from an upper end of the identifying and conveying section 13 towards a lefthand surface 4b of the machine body 4 and opens to the lefthand surface 4b. The connecting and conveying section 15 receives from the identifying and conveying section 13 the banknotes S that have been identified by the identifying section 14 as objects of processing by the connecting unit 3 and conveys them from the base machine 2 towards the connecting unit 3.

[0023] The base machine 2 comprises a rejecting and conveying section 17 that extends from an upper end of the identifying and conveying section 13 towards the right side and is connected to a rejecting section 16 that is provided upward of the intake section 5. The rejecting and conveying section 17 conveys the banknotes S that have not been identified by the identifying section 14 as objects of processing by the connecting unit 3 to the rejecting section 16.

[0024] The rejecting section 16 stacks the banknotes S fed out from the end of the rejecting and conveying section 17 so that they can be taken out to the outside. The rejecting section 16 drops the banknotes S fed out from the rejecting and conveying section 17 towards a bottom surface 19 by means of an impeller 18, and the fed out banknotes S are stacked on the bottom surface 19 in a state in which each of their long sides abut a wall surface 20 along an inclination of the bottom surface 19 and are collected on one side.

[0025] The base machine 2 comprises in its interior a controlling section 21 that controls components comprising the base machine 2. The controlling section 21 controls the overall base machine 2 and is also connected to the connecting unit 3 via an interface in a communicable manner to output control commands.

[0026] In this way, in the base machine 2, the feed roller 9 kicks out the banknotes S inserted into the intake section 5 towards the intake port 8 side, and the intake roller 10 and the separating roller 11 separate them one by one and hand them over to the identifying and conveying section 13. Then, the identifying and conveying section 13 conveys the banknotes S and the identifying section 14 counts them while identifying them. Thereafter, the banknotes S that have been identified by the identifying section 14 as objects of processing are conveyed to the connecting unit 3 by the connecting and conveying section 15 while the banknotes S that have not been identified by the identifying section 14 as objects of processing are conveyed to the rejecting section 16 by means of the rejecting and conveying section 17.

<Configuration of the Connecting Unit>

[0027] The connecting unit 3 receives the banknotes S conveyed by the connecting and conveying section 15. The connecting unit 3 is configured by combining a stacking unit 3a that sorts the banknotes S according to their denominations and that stacks them so that they can be taken out to the outside, and a bundling unit 3b that stacks the banknotes S by a predetermined number (for instance, 100 sheets) and binds them with a bundling tape into bundles. It should be noted that the operator can arbitrarily choose which of the stacking process by the stacking unit 3a or the bundling process by the bundling unit 3b shall be executed.

[0028] The connecting unit 3 is not limited to one comprising each of the stacking unit 3a and the bundling unit 3b, and it could be provided with only either one of the stacking unit 3a or the bundling unit 3b.

Then, the stacking sections 23a to 23d perform stacking processes of the banknotes S that have been identified as objects of processing.

[0036] The bundling unit 3b comprises a connecting and conveying section 26a that is connected to the connecting and conveying section 22a, and a processing and conveying section 26b that branches from an intermediate position of the connecting and conveying section 26a and extends downward. The connecting and conveying section 26a receives the banknotes S from the connecting and conveying section 22a and conveys them. The bundling unit 3b can be connected to another bundling unit 3b on a side opposite to the stacking unit 3a, and in this case, the connecting and conveying section 26a conveys the banknotes S to the other bundling unit 3a.

[0037] The processing and conveying section 26b comprises a conveying main section 26c that receives the banknotes S from the connecting and conveying section 26a and conveys them downward, and a branching section 26d that branches from the conveying main section 26c.

[0038] An aligning and stacking section 27a is provided at an end of the conveying main section 26c, and an aligning and stacking section 27b is provided at an end of the branching section 26d. The aligning and stacking sections 27a, 27b perform aligning and stacking processes in which they respectively receive the banknotes S fed out from the processing and conveying section 26b and align and stack them in a horizontal posture in the vertical direction into a predetermined number of bundling units.

[0039]  The bundling unit 3b comprises a bundling section 28 that stacks and bundles the banknotes S by a predetermined number. The bundling section 28 comprises a descending and conveying section 29 that places the stacked banknotes S sent out from the aligning and stacking sections 27a, 27b in a horizontal state and descends them downward in the vertical direction. Downward of the aligning and stacking section 27a, the bundling section 28 also comprises a bundling mechanism section 30 for creating bundled banknotes, which are loose banknotes S that have been gathered by only a predetermined number of bundling units and united with a bundling tape, obtained by bundling stacked banknotes S, which have been descended and conveyed by the descending and conveying section 29 and sent out from the descending and conveying section 29 in a horizontal state, by a bunding tape.

[0040] Moreover, the bundling section 28 comprises an outwardly discharging section 31 for discharging the bundled banknotes created in the bundling mechanism section 30 to the outside. The outwardly discharging section 31 is, for instance, configured in that bundled banknotes can be received and pulled out from a front surface of a machine body 32 of the bundling unit 3b. It should be noted it could be a configuration in which the outwardly discharging section 31 is provided at a front surface of the bundling mechanism section 30, in which the bundled banknotes are conveyed to a bundled banknote outlet (not shown) provided at a front surface of the machine body 32, and in which the bundled banknotes can be discharged to the outside from the bundled banknote outlet.

[0041] The bunding unit 3b is provided in its interior with a controlling section 33 that controls the bundling unit 3b upon receiving control commands from the controlling section 21.

[0042] In this manner, the bundling unit 3b conveys the banknotes S received from the stacking unit 3a to the aligning and stacking sections 27a, 27b by means of the connecting and conveying section 26a and the processing and conveying section 26b, and conveys the banknotes S from the aligning and stacking sections 27a, 27b to the bundling section 28 by means of the descending and conveying section 29. Then, the bundling section 28 performs bundling processes of the banknotes S that have been identified as objects of processing.

[0065] When the bill press 100 is on standby, the first auxiliary pressing section 120 and the second auxiliary pressing section 130 are configured to maintain a horizontal posture during standby by their own weight or by biasing force of a coil spring (not shown) directed downward in the vertical direction, wherein the bottom surfaces 116, 123, and 133 are substantially flush.

[0066] On the other hand, when an upward force acts on the bottom surface 123, the first auxiliary pressing section 120 swings about the rotating shaft 117 clockwise in Fig. 8 as shown in Fig. 7 and Fig. 8. Further, when an upward force acts on the bottom surface 123, the second auxiliary pressing section 130 swings about the rotating shaft 117 counterclockwise in Fig. 8 as shown in Fig. 7 and Fig. 8.

[0067] It should be noted that in the present embodiment, the first auxiliary pressing section 120 and the second auxiliary pressing section 130 are provided to align in the front-rear direction in order to stably press the banknotes S that are elongated in the front-rear direction over a wide range. However, in case the banknote S have, for instance, a relatively short longitudinal dimension and the banknotes S can be stably pressed by only either one of the first auxiliary pressing section 120 or the second auxiliary pressing section 130, the other one of the first auxiliary pressing section 120 or the second auxiliary pressing section 130 can be omitted.

<Operations>

[0068] Next, operations of the banknote processing device 1 will be explained. First, the distance between the guide members 40, 41 is adjusted according to a width dimension of the banknotes S to be taken into the connecting unit 3.

[0069] As shown in Fig. 3 and Fig. 4, the tip section 122 passes through the opening section 40d and extends up to the vicinity of the front upright wall 44 without interfering the guide member 40, and the tip end 132 passes through the opening section 41d and extends up to the vicinity of the rear upright wall 45 without interfering the guide member 41. That is, the main pressing section 110, the first auxiliary pressing section 120 and the second auxiliary pressing section 130 are provided to cover the bottom surface section 6 in the front-rear direction when seen in a planar view.

[0070] The bill press 100 is arranged at a predetermined retracted position that is located substantially intermediate of the back wall surface section 7 in the vertical direction. At this time, the bottom surfaces 116, 123, and 133 are located further upward than the residual amount sensor 39.

[0071] When the banknotes S that are objects of processing are placed in a stacked state by the operator between the guide members 40, 41 and onto the bottom surface section 6, the banknotes S are positioned in the intake section 5 to be substantially central in the front-rear direction by means of the guide members 40, 41.

[0072] Next, when an "up-down" button (not shown) displayed on the operation displaying section 35 is pressed by the operator, the controlling section 21 makes the residual amount sensor 39 detect the amount of banknotes S placed on the intake section 5 on the condition that the residual sensor 37 has detected the banknotes S and that the gesture sensor 36 has detected that the position of a hand of the operator has separated from the gesture sensor 36 by a predetermined distance.

[0073] When the amount of banknotes S is less than the sensible amount, the controlling section 21 moves the bill press 100 downward by means of the pressing and driving mechanism (not shown) to press the banknotes S with the bill press 100. At this time, when the banknotes S are stacked substantially horizontally, the main pressing section 110, the first auxiliary pressing section 120 and the second auxiliary pressing section 130 abut the banknotes S with the bottom surfaces 116, 123, and 133 which are flush with each other and uniformly press the banknotes S downward.

[0074] However, when fine protrusions B for identifying types or for preventing counterfeiting are formed at ends in the longitudinal direction of the banknotes S and banknotes S of uneven thicknesses are stacked as shown in Fig. 10, height variations are caused at which portions at which the protrusions B of the stacked banknotes S overlap (right side of the image plane in Fig. 9) become locally higher as shown in Fig. 9.

[0075] Therefore, the second auxiliary pressing section 130 swings about the rotating shaft 117 in accordance with the height variations of the stacked banknotes S. Accordingly, the main pressing section 110 and the first auxiliary pressing section 120 press the banknotes S in horizontal postures while the second auxiliary pressing section 130 presses the banknotes S in an inclined posture so that the banknotes S are pressed on the entire surfaces in the front-rear direction.

[0076] On the other hand, when the amount of banknotes S is equal to or larger than the sensible amount, the controlling section 21 does not perform pressing with the bill press 100 but leaves the bill press 100 at the retracted position.

[0077] Next, when the "start" button (not shown) displayed on the operation displaying section 35 is pressed by the operator, the controlling section 21 causes the banknotes S stacked in the intake section 5 be taken in through the intake port 8 by means of the feed roller 9, the intake roller 10 and the separating roller 11.

[0078] At this time, when the amount of banknotes S is less than the sensible amount, the controlling section 21 causes the banknotes S to be taken in while pressing the banknotes S with the bill press 100 to the bottom surface section 6 side. The controlling section 21 descends the bill press 100 by means of the pressing and driving mechanism in accordance with the taking-in progress of the banknotes S.

[0079] On the other hand, when the amount of banknotes S is equal to or larger than the sensible amount, the controlling section 21 first causes the banknotes S to be taken in through the intake port 8 in a state in which the bill press 100 located at the retracted position is not pressing the banknotes S, and thereafter, when the amount of banknotes S placed on the bottom surface section 6 becomes less than the sensible amount, the bill press 100 is moved downward by means of the pressing and driving mechanism to cause the banknotes S to be taken in through the intake port 8 while pressing the banknotes S with the bill press 100.

[0080] Then, the controlling section 21 cooperates with the controlling sections 25, 33 to make the identifying section 14 identify and count the banknotes S taken into the interior of the banknote processing device 1 while conveying them by means of the identifying and conveying device 13, conveys the identified and counted banknotes S that are objects of processing in the connecting unit 3 to the connecting unit 3 by means of the connecting and conveying section 15, and makes the connecting unit 3 perform stacking processes or bundling processes. On the other hand, banknotes S other than the objects of processing in the connecting unit 3 are conveyed to the rejecting section 16 by means of the rejecting and conveying section 17.

[0081] It should be noted that in case banknotes S are reinserted (additionally inserted), the controlling section 21 moves the bill press 100 upward by a predetermined distance by means of the pressing and driving mechanism when the gesture sensor 36 detects that a hand of the operator is within a predetermined distance from the gesture sensor 36.

[0082] When banknotes S are reinserted (additionally inserted) to the intake section 5 by the operator, the banknote processing device 1 operates similarly to the above-described steps, and the controlling section 21 makes the residual amount sensor 39 detect the amount of banknotes S placed on the intake section 5 on the condition that the residual sensor 37 has detected the banknotes S and that the gesture sensor 36 has detected that the position of a hand of the operator has separated from the gesture sensor 36 by a predetermined distance.

[0083] Then, when the amount of banknotes S is less than the sensible amount, the bill press 100 is moved downward by means of the pressing and driving mechanism to press the banknotes S with the bill press 100 towards the bottom surface section 6 side.

[0084] On the other hand, when the amount of banknotes S is equal to or larger than the sensible amount, pressing with the bill press 100 is not performed but the bill press 100 is located at the retracted position. It should be noted that in case banknotes S are reinserted while banknotes S are being taken in at the intake section 5, this is performed without temporarily stopping the taking-in of banknotes S. When the residual sensor 37 stops sensing banknotes S with the progressing of the taking-in of banknotes S at the intake section 5, the controlling section 21 moves the bill press 100 upward by means of the pressing and driving mechanism back to the retracted position.

[0085] In this manner, the banknote processing device 1 according to the present embodiment has been configured to be the banknote processing device 1 that presses banknotes S placed on the intake section 5 by means of the bill press 100 towards the feed roller 9 and takes in the banknotes S into the machine body 4, wherein the bill press 100 comprises the main pressing section 110 that is provided to be movable up and down in the intake section 5 and can press the substantial center of the banknotes S, and the first auxiliary pressing section 120 and the second auxiliary pressing section 130 that are provided independently of the main pressing section 110 and can press regions of the banknotes S other than the substantial center.

[0086] With this configuration, also in case there are height variations in banknotes S stacked in the intake section 5 caused through overlapping protrusions B of the banknotes S, uneven abutment with the bill press 100 partially abutting the banknotes S is restricted and the banknotes S are stably pressed towards the feed roller 9 over a wide range since the main pressing section 110 presses the substantial center of the banknotes S while the first auxiliary pressing section 120 and the second auxiliary pressing section 130 can press the banknotes S in a swinging state in accordance with the height of the banknotes S so that the banknotes S can be smoothly sent into the machine body 4.

[0087] Further, the banknote processing device 1 has been configured in that the first auxiliary pressing section 120 and the second auxiliary pressing section 130 are respectively arranged in the front-rear direction that extends along the longitudinal direction of the banknotes S with the main pressing section 110 being the reference.

[0088] With this configuration, banknotes S that are elongated in the front-rear direction can be stably pressed over a wide range since the first auxiliary pressing section 120 and the second auxiliary pressing section 130 are arranged on both sides of the main pressing section 110 so that the banknotes S can be smoothly sent into the machine body 4.

[0089] Further, the banknote processing device 1 has been configured in that the first auxiliary pressing section 120 and the second auxiliary pressing section 130 are configured to be connected to the main pressing section 110 via a rotating shaft 117 provided to extend along the left-right direction and to be movable up and down in the intake section 5 in conjunction with the main pressing section 110 and to be swingable about the rotating shaft 117.

[0090] With this configuration, uneven abutment of the bill press 100 can be restricted with a simple configuration and banknotes S can be smoothly sent into the machine body 4 since the first auxiliary pressing section 120 and the second auxiliary pressing section 130 are movable up and down in the intake section 5 in conjunction with the main pressing section 110 and swing about the rotating shaft 117 in accordance with heights of the banknotes S.

<Modifications>

[0091] The bill press 100 is not limited to the above-described configuration, and it could be any one unless the configuration can locally press banknotes S according to heights of the banknotes S in case the heights of the stacked banknotes S are not even.

[0092] For instance, the first auxiliary pressing section 120 and the second auxiliary pressing section 130 are not limited to those that are connected to the main pressing section 110 via the rotating shaft 117 and move up and down in the intake section 5 in conjunction with the main pressing section 110, and they could be configured to be movable up and down in the intake section 5 independently of the main pressing section 110. The configuration might, for instance, be that such a first auxiliary pressing section 120 and a second auxiliary pressing section 130 are connected to the pressing and driving mechanism (not shown) similarly to the main pressing section 110 to slide up and down along the back wall surface section 7.

[0093] According to this configuration, it is possible to cope with height variations in banknotes S stacked in the intake section 5 since the first auxiliary pressing section 120 and the second auxiliary pressing section 130 move up and down in the intake section 5 independently of the main pressing section 110 so that the banknotes S can be accurately sent into the machine body 4.

[0094] Further, in case of processing banknotes S formed with protrusions B at ends in the short direction, it is possible to provide a third auxiliary pressing section on the right side in the left-right direction extending along the short direction of the banknotes S with the main pressing section 110 being the reference. In this case, the configuration might, for instance, be that a left end of the third auxiliary pressing section is supported by the frame 112 to be swingable about a rotating shaft (not shown) extending along the front-rear direction, that the third auxiliary pressing section maintains a horizontal posture when it is on standby by its own weight or by biasing force of a coil spring (not shown) directed downward in the vertical direction and, in case the stacked banknotes S are locally higher on the right side in the left-right direction, that the right side in the left-right direction of the banknotes S is locally pressed.

[0095] According to this configuration, the third auxiliary pressing section arranged on the right side in the left-right direction of the main pressing section 110 can stably press banknotes S formed with protrusions at ends in the short direction and sent them smoothly into the machine body 4.

[0096] Further, the present invention can be modified in various ways as long as it does not depart from the spirit of the present invention, and it is obvious that the present invention covers such modifications. Moreover, any of the above-mentioned embodiments and modifications can be combined or all of them can be combined.

[0097] Objects of processing of the paper sheet processing device according to the present invention are applicable to devices processing all types of paper sheets besides banknotes, such as notes like gift certification, checks, and bills or securities.
