The present invention relates to a paper-sheet feeding device configured for successively feeding a plurality of paper-sheets stored in a paper-sheet storing unit, to an outside, one by one, and in particular relates to the paper-sheet feeding device that can simplify the entire construction thereof, reduce the cost and increase a feeding speed of the paper-sheets.
The paper-sheet feeding device used for a banknote counter or the like is configured for successively feeding the paper-sheets (e.g., banknotes or the like) stacked therein, one by one, so as to carry them to the outside.
Typically, in such a paper-sheet feeding device as described above, a feed roller and a thickness adjustment member are provided to a feeding unit for the paper-sheets, with a gap corresponding to thickness of one paper-sheet. Thus, the paper-sheet fed into the feeding unit can be fed out therefrom, one by one, while being controlled upon passing through the gap between the feed roller and the thickness adjustment member. However, in such a paper-sheet feeding device, when the paper-sheets are inserted and stuck between the feed roller and the thickness adjustment member, while being overlapped in two sheets or more, the feed roller will be in a locked state, and rotation of the feed roller will be stopped. In such a case, it will take unduly time and labor to remove such stuck paper-sheets.
To solve this problem, the paper-sheet feeding device as disclosed in JP5-8878A has been proposed. Now, such a conventional paper-sheet feeding device is described, with reference to
As shown in
The feed roller 60, as shown in
The pressure roller 70, as shown in
Furthermore, a pressure roller shaft drive transmission mechanism (not shown) adapted for driving the pressure roller shaft 71 to be continuously rotated is provided to the pressure roller shaft 71. Specifically, this pressure roller shaft drive transmission mechanism is provided to rotate the pressure roller shaft 71, at any time, at a low speed, in a direction reverse to the feed-out direction of the paper-sheet P, i.e., in the direction designated by another arrow as depicted in
Next, the feed-out operation for the paper-sheet P, at the nip part N in such a conventional paper-sheet feeding device as shown in
a) is a diagram schematically showing one exemplary state in which no paper-sheet P is fed to the nip part N between the feed roller 60 and the pressure roller 70. In this state, the feed roller 60 is continuously rotated in the feed-out direction of the paper-sheet P. Since the feed roller 60 is pressed against the pressure roller 70, a torque for driving the pressure roller 70 to be rotated together with the feed roller 60 is transmitted to the pressure roller 70 from the feed roller 60. This torque that is applied to rotate the pressure roller 70 (i.e., the torque applied to the pressure roller 70 in the circumferential direction thereof) is set greater than the predetermined torque set in the torque limiter 73. Therefore, the rotation of the pressure roller 70, relative to the pressure roller shaft 71, in the feed-out direction of the paper-sheet P, is allowed. Thus, as shown in
Thereafter, as shown in
However, if two paper-sheets P are accidentally kicked out by the kicker roller 80, while being overlapped with each other, such two overlapped paper-sheets P will be fed to the nip part N between the feed roller 60 and the pressure roller 70, as shown in
However, there are various problems still remaining in such a conventional paper-sheet feeding device. First, it is necessary to provide the pressure roller shaft drive transmission mechanism, in order to drive the pressure roller shaft to be continuously rotated. Therefore, the construction of the paper-sheet feeding device becomes considerably complicated, thus increasing the production cost. Secondly, as shown in
Additionally, in the conventional paper-sheet feeding device, for example, when the two paper-sheets P are fed, accidentally, at a time, to the nip part N, after the paper-sheets P are fed, normally, one by one, to the nip part N, as shown in
The present invention was made in view of the problems as described above. Therefore, it is an object of the present invention to provide an improved paper-sheet feeding device that can eliminate the need for providing the aforementioned drive transmission mechanism for rotating the pressure roller as well as applying a torque limiter having a relatively low durability to the pressure roller, thereby simplifying the entire construction of the device as well as achieving significant cost reduction and desired increase of the feed-out speed of the paper-sheets.
The present invention is a paper-sheet feeding device comprising: a feed roller configured to be continuously rotated, upon feeding a paper-sheet, wherein the feed roller has a feed roller friction part provided around an outer circumferential surface thereof and configured to be in contact with a surface of the paper-sheet, thereby feeding the paper-sheet; a pressure roller configured to be pressed against the feed roller and forming a nip part, together with the feed roller, wherein the pressure roller has a pressure roller friction part provided around an outer circumferential surface thereof and having a smaller coefficient of friction against the paper-sheet, as compared with the coefficient of friction between the feed roller friction part and the paper-sheet; a pressure roller shaft provided to extend along an axis of the pressure roller and configured not to be rotated in a feed-out direction of the paper-sheet; and a torque limiter provided between the pressure roller and the pressure roller shaft and configured to allow the pressure roller to be rotated in the feed-out direction of the paper-sheet, relative to the pressure roller shaft, when a torque greater than a predetermined torque is applied to the pressure roller along a circumferential direction thereof, while interlocking the pressure roller with the pressure roller shaft, when the torque applied to the pressure roller along the circumferential direction thereof is less than the predetermined torque, wherein the predetermined torque is set less than a frictional torque directly generated between the feed roller friction part and the pressure roller friction part at the nip part, while being set greater than both the frictional torque generated between the pressure roller friction part and the paper-sheet at the nip part and the frictional torque generated between a pair of paper-sheets at the nip part.
According to this paper-sheet feeding device, the pressure roller is rotated together with the feed roller, when no paper-sheet is fed to the nip part between the feed roller and the pressure roller. Meanwhile, when one paper-sheet is fed to the nip part, the pressure roller will be interlocked with the pressure roller shaft, while not being rotated in the feed-out direction. In this case, since the coefficient of friction between the feed roller friction part and the paper-sheet is greater than the coefficient of friction between the pressure roller friction part and the paper-sheet, the one paper-sheet will be fed out from the nip part, while being moved together with the rotation of the feed roller. Again, the pressure roller will be interlocked with the pressure roller shaft, while not being rotated in the feed-out direction, when two or more paper-sheets are accidentally fed to the nip part, while being overlapped with one another. In this case, one paper-sheet, positioned nearest to the feed roller, among such a plurality of overlapped paper-sheets, will be fed out from the nip part, while being moved together with the rotation of the feed roller. However, at this time, the other paper-sheets are not fed out from the nip part.
In this manner, according to the paper-sheet feeding device of this invention, there is no need for providing any drive transmission mechanism for driving the pressure roller to be rotated. Therefore, the construction of such a paper-sheet feeding device can be significantly simplified, leading to substantial cost reduction. Additionally, only in a period of time during which no paper-sheet is fed between the feed roller and the pressure roller, slipping against the torque exerted from the torque limiter occurs between the pressure roller and the pressure roller shaft. Therefore, even such a torque limiter as one having relatively low durability can be applied to this paper-sheet feeding device, thus significantly reducing the cost required for the torque limiter. Furthermore, as compared with the case in which the rotational direction of the pressure roller is switched from the feed-out direction of the paper-sheet to the reverse direction thereof, relative to the pressure roller shaft, during the feed-out operation, the operational mode of the pressure roller in the paper-sheet feeding device of this invention should only be changed from a mode of rotation in the feed-out direction of the paper-sheet into a stopped condition, relative to the pressure roller shaft. Therefore, the time required for switching the operational mode can be reduced. Accordingly, the speed for feeding the paper-sheets can be increased, as compared with the conventional device.
In the paper-sheet feeding device of this invention, it is preferred that a one-way clutch is provided to the pressure roller shaft, wherein the one-way clutch is configured to allow the pressure roller shaft to be rotated only in the direction reverse to the feed-out direction of the paper-sheet. With such a one-way clutch, the pressure roller can be rotated together with the feed roller, also in the case in which the feed roller is rotated in the feed-in direction of the paper-sheet, thus enabling this paper-sheet feeding device to perform a desired feed-in operation for the paper-sheets.
In the paper-sheet feeding device of this invention, it is preferred that the pressing force for pressing the pressure roller against the feed roller is set within a range of 3.92N to 7.84N (0.8813 lbf to 1.7625 lbf), wherein the predetermined torque applied from the torque limiter is set within a range of 0.0686 N·m to 0.1078N·m (0.0506 lb·ft to 0.0795 lb·ft). If the predetermined torque is unduly large, the pressure roller may be interlocked with the pressure roller shaft, even when no paper-sheet is fed to the nip part and thus the feed roller friction part of the feed roller is directly contacted with the pressure roller friction part of the pressure roller. In such a case, the pressure roller would remain in a stationary condition, even though the feed roller is rotated in the feed-out direction of the paper-sheet. Thus, some friction would be always generated between the feed roller friction part of the feed roller and the pressure roller friction part of the pressure roller, leading to considerable wear of the feed roller friction part and/or pressure roller friction part in a shorter time. In contrast, if the predetermined torque T is unduly small, the pressure roller may be rotated in the feed-out direction of the paper-sheet, relative to the paper-sheet roller shaft, even in a period of time during which one paper-sheet is fed through the nip part. Namely, in such a case, slipping against the toque exerted from the torque limiter would occur between the pressure roller and the pressure roller shaft, even in the period of time during which the one paper-sheet is fed through the nip part. Therefore, the life span of the torque limiter may be considerably shortened. It is noted that the paper-sheet feeding device of this invention can be applied to various paper-sheets, specifically Japanese and/or US banknotes as well as banknotes of the other countries in the world or paper-sheets other than the banknotes, such as checks or the like, each having different thickness and/or quality of the material, by changing the pressing force of the pressure roller against the feed roller and/or altering the predetermined torque applied from the torque limiter.
Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
General construction of the paper-sheet storing and feeding device of this embodiment, specific construction of each component thereof, operations and effects thereof, and variations and modifications thereof will be described below, successively.
First, the general construction of the paper-sheet storing and feeding device of this embodiment will be described.
As shown in
Below the feed roller 10, a guide member 45 configured for guiding each paper sheet P fed out from the nip part N is provided. Additionally, a pair of left and right first grip rollers 46 and a pair of left and right second grip rollers 47 are contacted with the feed rollers 10, respectively. The first grip rollers 46, the second grip rollers 47 and the feed rollers 10 are respectively configured for further carrying each paper-sheet P fed out from the nip part N. In the vicinity of the feed rollers 10, a pair of left and right third grip rollers 48 and a pair of left and right carrier rollers 49 respectively contacted with the third grip rollers 48, are provided, respectively. The third grip rollers 48 and carrier rollers 49 are respectively configured for carrying out each paper-sheet P fed out from another nip part formed between the feed rollers 10 and the second grip rollers 47.
Hereinafter, each component of the paper-sheet storing and feeding device will be described in more detail.
The kicker roller 30, as shown in
Each feed roller 10, as shown in
The pressure roller 20, as shown in
Each rubber 23 of the pressure roller 20 forms the nip part N, together with the rubber 13 of each feed roller 10. The width of each rubber 23 of the pressure roller 20 is set to be slightly smaller than the width of the rubber 13 of each feed roller 10. The coefficient of friction μ1 of each rubber 23 of the pressure roller 20 against each paper-sheet P is less than the coefficient of friction μ2 of the rubber 13 of each feed roller 10 against the paper-sheet P.
As shown in
Between the base part 22 of the pressure roller 20 and the pressure roller shaft 21, a torque limiter 24 is provided. The torque limiter 24 is configured to allow the pressure roller 20 to be rotated, in a feed-out direction of the paper-sheet P, relative to the pressure roller shaft 21, when a torque greater than a predetermined torque T is applied to the pressure roller 20 along the circumferential direction thereof. On the contrary, this torque limiter 24 is configured to interlock the pressure roller 20 with the pressure roller shaft 21, when the torque less than the predetermined torque T is applied to the pressure roller 20 along the circumferential direction thereof. In this case, the predetermined torque T set in the torque limiter 24 is set less than frictional torque N3 directly generated between the rubbers 13 of the feed rollers 10 and the rubbers 23 of the pressure roller 20 at the nip part N, while being set greater than the frictional torque N1 generated between the rubbers 23 of the pressure roller 20 and each paper-sheet P at the nip part N and the frictional torque N4 generated between the two overlapped paper-sheets at the nip part N.
Now, assuming that the coefficient of friction between the rubber 13 of each feed roller 10 and each rubber 23 of the pressure roller 20 is designated by μ3, the aforementioned frictional torque N3 can be expressed by the following equation.
N3=μ3×P1 (1)
As described above, P1 designates the pressing force of the pressure roller 20 against the feed rollers 10.
Meanwhile, the aforementioned frictional torque N1 can be expressed as follows.
N1=μ1×P1 (2)
Additionally, assuming that the coefficient of friction between the two overlapped paper-sheets P is designated by μ4, the aforementioned frictional torque N4 can be expressed by the following equation.
N4=μ4×P1 (3)
Generally, the coefficient of friction μ1 of each rubber 23 of the pressure roller 20 against the paper-sheet P is much greater than the coefficient of friction μ4 between the two overlapped paper-sheets P. Therefore, the predetermined torque T is set at a value satisfying the following formula.
μ1×P1<T÷R<μ3×P1 (4)
In this formula (4), R denotes a radius (e.g., 13 mm) of the pressure roller 20.
In addition, one-way clutches 25 (see
The holding member 40 is configured to be optionally advanced and retracted, relative to the kicker roller 30, on the table 42 (i.e., the holding member 40 can be moved in the left and right directions in
A rubber 41 is attached to a surface, on the side of the kicker roller 30, of the holding member 40, such that the rubber 41 can be in contact with the surface of the rearmost paper-sheet P among the plurality of paper-sheets P placed in the stacked condition on the table 42. Thus, when the holding member 40 is advanced, the rubber 41 will push the plurality of paper-sheets P forward (in the right direction in
It is noted that such a member as one attached to the surface, on the side of the kicker roller 30, of the holding member 40 is not limited to the rubber 41 as described above. For instance, any suitable member, having frictional torque, against the paper-sheet P, greater than the aforementioned frictional torque N4 generated between the two overlapped paper-sheets P, may be used.
Next, an operation of this embodiment constructed as described above will be discussed, with reference to
First, the operation for feeding the plurality of paper-sheets P in the stacked condition, to the outside, successively, one by one, will be described.
First of all, the plurality of paper-sheets P are placed between the holding member 40 and the kicker roller 30 on the table 42. Then, the holding member 40 is advanced toward the kicker roller 30 (or moved in the right direction in
In this case, the holding member 40 is pressed from the back on the table 42, such that it can be always advanced toward the kicker roller 30. Accordingly, even after a part of the paper-sheets P, among the paper-sheets P in the stacked condition, are kicked out by the kicker roller 30, the remaining paper-sheets P can be always kept in the standing position.
In this way, once the paper-sheets P are stacked in the standing position by the holding member 40, the kicker roller 30 and feed rollers 10 are rotated, in the directions designated by the arrows depicted in
The paper-sheet P kicked out downward by the kicker roller 30 is then fed to the nip part N formed between the rubber 13 of each feed roller 10 and each rubber 23 of the pressure roller 20. Now, referring to
a) is a schematic view showing a state in which no paper-sheet P is fed to the nip part N between the feed rollers 10 and the pressure roller 20. In this case, as described above, each feed roller 10 is continuously rotated in the feed-out direction of the paper sheet P, while being pressed against the pressure roller 20. Thus, the pressure roller 20 is rotated together with the feed rollers 10, while receiving the pressing torque from the rotating feed rollers 10. This torque exerted on the pressure roller 20, for rotating it together with the feed rollers 10 (i.e., the torque applied to the pressure roller 20 along the circumferential direction thereof) corresponds to the frictional torque N3 directly generated between the rubbers 13 of the feed rollers 10 and the rubbers 23 of the pressure roller 20 at the nip part N. Since such torque applied to the pressure roller 20, for rotating it together with the feed rollers 10, is greater than the predetermined torque T set in the torque limiter 24, the rotation of the pressure roller 20 in the feed-out direction of the paper-sheet P, relative to the pressure roller shaft 21, is allowed. Thus, the pressure roller 20 will be rotated together with the feed rollers 10 in the direction designated by an arrow as depicted in
Thereafter, as shown in
However, when two paper-sheets P are kicked out, accidentally, while being overlapped with each other, by the kicker roller 30, as shown in
Accordingly, in the case in which such two overlapped paper-sheets P are fed together to the nip part N between the feed rollers 10 and the pressure roller 20, the torque applied to the pressure roller 20 along its circumferential direction will be the frictional torque N4 exerted between the two overlapped paper-sheets P. However, as described above, since this frictional torque N4 is less than the predetermined torque T exerted from the torque limiter 24, the rotation of the pressure roller 20 in the feed-out direction of the paper-sheet P, relative to the pressure roller shaft 21, will not be allowed and the pressure roller 20 will be interlocked with the pressure roller shaft 21. Accordingly, also in this case, as shown in
Thereafter, the paper-sheet P fed out from the nip part N between the feed rollers 10 and the pressure roller 20 will be carried by the first grip rollers 46 and second grip rollers 47 along the guide member 45, and finally carried out from another nip part between the third grip rollers 48 and carrier rollers 49.
Next, an operation, for storing the plurality of paper-sheets P successively fed in from the outside as well as for bringing them into the stacked condition, will be discussed, with respect to the paper-sheet storing and feeding device of this embodiment.
First, the paper-sheets P are inserted, one by one, between the third grip rollers 48 and carrier rollers 49. Each of the inserted paper-sheets P is then fed, along the guide member 45, to the nip part N between the feed rollers 10 and the pressure roller 20. In this case, each feed roller 10 is continuously rotated in the direction reverse to the direction designated by the arrow depicted in
Thereafter, a feed-in operation for the paper-sheets P successively fed to the nip part N is performed, one by one, by the feed rollers 10. As described above, the one-way clutches 25, which are provided to the pressure roller shaft 21 for pivoting the pressure roller 20, is configured to allow the pressure roller shaft 21 to be rotated in the direction reverse to the feed-out direction of the paper-sheet P, i.e., in the feed-in direction of the paper-sheet P. Again, since each feed roller 10 is pressed against the pressure roller 20, the pressure roller 20 will be rotated together with the feed rollers 10. As a result, the pressure roller 20 will be rotated in a counterclockwise direction in
Thereafter, the plurality of paper-sheets P successively fed and stacked onto the table 42 will be held in the standing position between the holding member 40 and the kicker roller 30.
As discussed above, according to the paper-sheet storing and feeding device of this embodiment, the torque limiter 24 is provided between the pressure roller 20 and the pressure roller shaft 21. In this case, the torque limiter 24 is configured to allow the pressure roller 20 to be rotated, in the feed-out direction of the paper-sheet P, relative to the pressure roller shaft 21, when the torque greater than the predetermined torque T is applied to the pressure roller 20 along the circumferential direction thereof. In addition, this torque limiter 24 is configured to interlock the pressure roller 20 with the pressure roller shaft 21, when the torque less than the predetermined torque T is applied to the pressure roller 20 along the circumferential direction thereof. The predetermined torque T is set at a value less than the frictional torque N3 directly generated between the rubbers 13 of the feed rollers 10 and the rubbers 23 of the pressure roller 20 at the nip part N, while being set greater than both of the frictional torque N1 generated between the rubbers 23 of the pressure roller 20 and the paper-sheet P at the nip part N and the frictional torque N4 generated between the two overlapped paper-sheets P at the nip part N. Furthermore, the pressure roller shaft 21 is configured not to be rotated in the feed-out direction of the paper-sheet P. Therefore, as described above, when no paper-sheet P is fed to the nip part N between the feed rollers 10 and the pressure roller 20, the pressure roller 20 is rotated together with the feed rollers 10. Meanwhile, when one paper-sheet P is fed to the nip part N, the pressure roller 20 will be interlocked with the pressure roller shaft 21. Thus, the pressure roller 20 will be no longer rotated in the feed-out direction of the paper-sheet P. In this case, since the coefficient of friction μ1 between the rubber 13 of each feed roller 10 and the paper-sheet P is greater than the coefficient of friction μ2 between each rubber 23 of the pressure roller 20 and the paper-sheet P, the paper-sheet P will be fed out from the nip part N together with the rotation of the feed roller 10. Similarly, when the two or more paper-sheets P are fed to the nip part N, while being overlapped with one another, the pressure roller 20 will be interlocked with the pressure roller shaft 21 and thus will no longer be rotated in the feed-out direction of the paper-sheet P. In this case, the one paper-sheet P nearest to the feed rollers 10, among such two or more overlapped paper-sheets P, will be fed out from the nip part N, while being moved together with the rotation of the feed rollers 10. However, at this time, the other paper-sheets P are not fed out from the nip part N.
In this manner, according to the paper-sheet storing and feeding device of this embodiment, there is no need for providing any special drive transmission mechanism for driving the pressure roller 20 to be rotated. This can significantly simplify the construction of the paper-sheet storing and feeding device, leading to a cost reduction. In addition, only in the period of time during which no paper-sheet is fed between the feed rollers 10 and the pressure roller 20, slipping against the torque exerted from the torque limiter 24 occurs between the pressure roller 20 and the pressure roller shaft 21. Therefore, even such a torque limiter 24 as one having relatively low durability can be applied to this paper-sheet storing and feeding device, thus significantly reducing the cost required for the torque limiter 24. Furthermore, as compared with the conventional device configured for switching the rotational direction of the pressure roller, from the feed-out direction of the paper-sheet to the reverse direction thereof (i.e., the feed-in direction), relative to the pressure roller shaft, during the feed-out operation, the operational mode of the pressure roller 20 of the paper-sheet storing and feeding device of the above embodiment should only be changed from a mode of rotation in the feed-out direction of the paper-sheet P, relative to the pressure roller shaft 21, into the stationary or stopped state. Therefore, the time required for switching the operational mode can be reduced. Thus, the speed for feeding out the paper-sheets P can be increased, as compared with the conventional device.
Additionally, the one-way clutches 25 are provided to the pressure roller shaft 21, wherein the one-way clutches 25 are configured to allow the pressure roller shaft 21 to be rotated only in the direction reverse to the feed-out direction of the paper sheet P. With such a provision of the one-way clutches 25, the pressure roller 20 can be rotated together with the feed rollers 10, in the case in which the feed rollers 10 are rotated in the feed-in direction of the paper-sheet P. As such, a desired feed-in operation for the paper-sheet P can be performed by this paper-sheet storing and feeding device.
Specifically, the predetermined torque T is set within a range of 0.0686 N·m to 0.1078 N·m (0.0506 lb·ft to 0.0795 lb·ft). If the predetermined torque T is unduly large, as compared with the above range, the pressure roller 20 may be interlocked with the pressure roller shaft 21, even when no paper-sheet P is fed to the nip part N and hence the rubber 13 of each feed roller 10 is directly contacted with each rubber 23 of the pressure roller 20. Therefore, in such a case, the pressure roller 20 would remain in the stationary state, at any time, even through the feed rollers 10 are rotated in the feed-out direction of the paper-sheet P. Accordingly, some friction would be always generated between the rubber 13 of each feed roller 10 and each rubber 23 of the pressure roller 20, thus wearing out the rubber 13 and/or rubber 23 in a shorter time. Contrary, if the predetermined torque T is unduly small, the pressure roller 20 may be rotated in the feed-out direction of the paper-sheet P, relative to the pressure roller shaft 21, even in a period of time during which one paper-sheet P is fed through the nip part N. In such a case, abrasive slipping against the toque exerted from the torque limiter 24 would occur between the pressure roller 20 and the pressure roller shaft 21, even in the period of time during which the one paper-sheet P is fed through the nip part N. Therefore, the life span of the torque limiter 24 should be considerably shortened.
It should be appreciated that the paper-sheet storing and feeding device described above can be applied to various paper-sheets P, specifically Japanese and/or US banknotes as well as banknotes of the other countries in the world or paper-sheets P other than the banknotes, such as checks or the like, each having different thickness and/or quality of the material, by changing the pressing force P1 of the pressure roller 20 against the feed rollers 10 and/or adequately adjusting the predetermined torque T set in the torque limiter 24.
In addition, according to the paper-sheet storing and feeding device as described above, both of the feed-out operation and feed-in operation for the paper-sheets P can be performed with the same transport path, thereby substantially downsizing the paper-sheet storing and feeding device.
While the paper-sheet storing and feeding device capable of performing both of the feed-out operation and feed-in operation for the paper-sheets has been discussed with respect to the above embodiment, the present invention is not limited to such an aspect. For instance, this invention is also applicable to the paper-sheet feeding device adapted for feeding out the paper-sheets, successively, one by one, while having no function for feeding in and storing the paper-sheets therein.
While the paper-sheet storing and feeding device related to the above embodiment has been described as one configured to place the plurality of paper-sheets on the table in the vertically standing position, the present invention is not limited to such a type. For instance, this invention can also be applied to the paper-sheet storing and feeding device or paper-sheet feeding device, which is configured to place the plurality of paper-sheets on the table in a horizontally stacked condition.
