In the vicinity of the feed roller 20, a pair of left and right third grip rollers 27 and a pair of left and right unloading rollers 28 that are in contact with the third grip roller 27 are provided. These third grip rollers 27 and the carry-out roller 28 carry out the paper sheet P fed out from the nip between the feed roller 20 and the second grip roller 26 along the guide member 29.

Hereinafter, each component of such a paper sheet storage and feeding device will be described in more detail.
As shown in FIG. 1, the kicker roller 10 is in contact with the surface of the frontmost paper sheet P among a plurality of paper sheets in an accumulated state. It is designed to rotate continuously in the direction of the arrow. As shown in FIGS. 3 to 5, the kicker roller 10 has a substantially disc-shaped base portion 11 made of, for example, plastic or metal, and a frontmost paper sheet formed on a part of the outer periphery of the base portion 11 in the circumferential direction. And a rubber member (high friction portion) 12 for kicking out the kind P. The rubber member 12 covers, for example, about ¼ of the outer peripheral surface of the base portion 11.
The diameter of the kicker roller 10 is about 40 mm, for example, and the width is about 12 mm, for example.

As shown in FIGS. 3 to 5, the base portion 11 of the kicker roller 10 has end portions 11a on both sides in the width direction that are recessed at least in the vicinity of the rubber member 12 with respect to the central portion 11b. Here, the widths of the end portions 11a and the central portion 11b are each about 4 mm. Specifically, the depth (the size of the step) of the recess with respect to the central portion 11b of the end portion 11a is maximized at the boundary portion 15 between the base portion 11 and the rubber member 12 on the outer periphery of the kicker roller 10. Then, the depth of the dent gradually decreases on the outer peripheral surface of the base portion 11 from the boundary portion 15 in the circumferential direction, and the portion 16 on the outer peripheral surface of the base portion 11 that faces the mounting portion of the rubber member 12 in the diameter direction. In FIG. 5, no step is generated between the end portion 11a and the central portion 11b.
As shown in FIGS. 3 and 4, at the boundary portion 15 between the base portion 11 and the rubber member 12, there is substantially a step between the central portion 11 b of the base portion 11 and the rubber member 12. However, there is a step between the end portion 11 a of the base portion 11 and the rubber member 12.
The base portion 11 is not limited to those in which the end portions 11a on both sides in the width direction are recessed with respect to the central portion 11b, and even if the end portion 11a on only one side is recessed with respect to the central portion 11b. Good. Moreover, as shown in FIG. 6, each base | substrate part 11 may be formed so that each edge part 11a of only the outer side in the combination body of a pair of left and right kicker rollers 10 may each be depressed with respect to the center part 11b.

As shown in FIG. 1, the feed roller 20 continuously rotates in the direction of the arrow in FIG. 1 when the paper sheet P is fed out. The feed roller 20 includes a substantially disc-shaped base portion 21 made of, for example, plastic or metal, and a rubber member (high friction portion) 22 formed on the entire outer periphery of the base portion 21. The rubber member 22 abuts on the surface of the paper sheet P kicked out by the kicker roller 10 and feeds out the paper sheet.
As shown only in FIGS. 7 and 8, a pair of flanges 23 made of, for example, plastic are attached to both sides of the combination of the base portion 21 and the rubber member 22. As shown in FIG. 8, the flange 23 has a protruding portion 23 a that protrudes by 0.2 mm, for example, radially outward of the feed roller 20 from the rubber member 22.
The diameter of the feed roller 20 is about 30 mm, for example, and the width is about 8 mm, for example.

As shown in FIG. 1, the pressure roller 30 is provided so as to be in pressure contact with the feed roller 20. As shown in FIG. 7, the press roller 30 includes a substantially disc-shaped base portion 31 made of, for example, plastic or metal, and a rubber member (high friction portion) 32 formed on the entire outer periphery of the base portion 31. have.
The rubber member 32 of the pressure roller 30 forms a gate portion (nip) G with the rubber member 22 of the feed roller 20. As shown in FIG. 8, the width of the rubber member 32 of the pressure roller 30 is configured to be slightly shorter than the width of the rubber member 22 of the feed roller 20.
The pressure roller 30 further includes a torque limiter (not shown) inside. When there is no paper sheet between the feed roller 20 and the pressure roller 30, the pressure roller 30 has a torque higher than the set torque. Is applied, and the pressure roller 30 is rotated with the feed roller 20. On the other hand, when one or more sheets are sandwiched between the feed roller 20 and the pressure roller 30, only a torque smaller than the set torque is applied to the pressure roller 30. For this reason, the pressure roller 30 is a torque limiter. The rotation is forcibly stopped by. As a result, only one paper sheet that is in contact with the feed roller 20 is fed out by the rotation of the feed roller 20, and the conveyance of the plurality of paper sheets at the gate portion G is suppressed.

As described above, the pressure contact type gate portion G is formed between the feed roller 20 and the pressure contact roller 30, so that the paper sheets P fed out by the feed roller 20 are separated one by one by the gate portion G. Will come to be.
The diameter of the pressure roller 30 is about 26 mm, for example, and the width is about 6 mm, for example.

  A one-way clutch (not shown) is connected to the pressure roller 30 as a holding portion that holds the pressure roller 30. Since the one-way clutch is installed, the pressure roller 30 can freely rotate without being affected by the torque limiter when a paper sheet is fed.

The bill presser member 40 is movable forward and backward on the mounting table 45 toward the kicker roller 10 (movable in the left-right direction in FIG. 1), and the tag presser member 40 moves toward the kicker roller 10. By moving forward (by moving to the right in FIG. 1), the plurality of paper sheets placed between the bill holding member 40 and the kicker roller 10 are maintained in the standing state. Yes.
A rubber member (high friction portion) 41 that abuts against the surface of the last sheet among a plurality of sheets stacked on the mounting table 45 is provided on the surface of the tag holding member 40 on the kicker roller 10 side. Is attached, and the plurality of paper sheets in which the rubber member 41 is in an accumulated state are pushed forward (rightward in FIG. 1) when the bill presser member 40 moves forward to be in a standing state.
Here, the member attached to the surface of the bill holding member 40 on the kicker roller 10 side is not limited to the rubber member 41 described above, and a member having a friction force larger than the friction force acting between the sheets. If it is.

  As shown in FIGS. 1 and 2, the stopper member 50 is provided in the vicinity of the kicker roller 10, and can be moved forward and backward toward the foremost paper sheet P that is stacked on the mounting table 45. Yes. The stopper member 50 has a hollow portion that opens in the forward / backward direction so as not to collide with the kicker roller 10 (see FIG. 2), and the kicker roller 10 passes through the hollow portion of the stopper member 50. Yes. As shown in FIGS. 9 and 10, the stopper member 50 includes a stopper lever 50a that can be moved forward and backward toward the foremost paper sheet P, and the paper sheet P side of the stopper lever 50a (see FIG. 9). Stopper rubber (high friction part) 50b attached to the left side). Here, FIG. 9 is a side view showing a state of the stopper member 50 and the stopper member operation cam 51 when the paper sheet is kicked out, and FIG. 10 is a diagram showing the stopper member 50 and the stopper member when the paper sheet is held. FIG. 5 is a side view showing a state of an operation cam 51.

The lower end of the stopper lever 50a is pivotally supported in the vicinity of the shaft of the feed roller 20, and extends upward from the lower end. And this stopper lever 50a can be rock | fluctuated in the left-right direction of FIG. 9 centering on the pivoted lower end part. The stopper lever 50a is constantly applied with a force acting so as to be separated from the paper sheet P (move to the right in FIG. 9) by a retractor (not shown) such as a spring. Therefore, the stopper lever 50a is separated from the paper sheet P as long as a force acting to advance toward the paper sheet P is not applied to the paper sheet P by a stopper member operation cam 51 described later (FIG. 9). Rotate around the lower end.
The stopper rubber 50b is attached in the vicinity of an intermediate position of the stopper lever 50a, and protrudes from the stopper lever 50a to the paper sheet P side (left side in FIG. 9). Note that two stopper rubbers 50b are attached to the left and right of one stopper member 50 as shown in FIG.
Further, as shown in FIG. 9, a circular rotating plate 52 is rotatably attached to a side surface slightly above the intermediate position of the stopper member 50.

In the stopper member 50, when the paper sheet P is kicked out by the kicker roller 10, the stopper lever 50a is retracted from the frontmost paper sheet P (see FIG. 9), and the stopper rubber 50b is connected to the frontmost paper sheet P. It is formed so as not to touch. At this time, as shown in FIG. 9, the stopper rubber 50 b of the stopper member 50 is retracted by, for example, 1.59 mm from the outer peripheral surface of the kicker roller 10 in the direction toward the paper sheet P.
Further, when the paper sheet P on the mounting table 45 is not kicked out, the stopper member 50 advances toward the foremost paper sheet P (see FIG. 10), and the stopper rubber 50b In contact with the foremost paper sheet P, the paper sheet P is pressed backward (left side in FIG. 10). At this time, as shown in FIG. 10, the stopper rubber 50 b of the stopper member 50 is advanced by, for example, 1 mm from the outer peripheral surface of the kicker roller 10 in the direction toward the paper sheet P.

As shown in FIGS. 9 and 10, the stopper member operation cam 51 is attached at its center to the shaft of the kicker roller 10, and rotates in synchronization with the kicker roller 10. The stopper member operation cam 51 has a substantially disk shape, and the outer peripheral surface of the stopper member operation cam 51 has a distance between the first outer peripheral surface 51a having a semicircular cross-section and the first outer peripheral surface 51a. The second outer peripheral surface 51b is shorter than the radius.
As shown in FIGS. 9 and 10, the outer peripheral surface of the stopper member operation cam 51 is in contact with the outer peripheral surface of a rotating plate 52 that is rotatably attached to the stopper member 50. Specifically, the frontmost paper sheet P is kicked out from the rubber member 12 from the kicking start timing at which the rubber member 12 of the kicker roller 10 starts to contact at least the frontmost paper sheet P. The outer peripheral surface of the rotating plate 52 comes into contact with the second outer peripheral surface 51b of the outer peripheral surface of the stopper member operation cam 51 until the kicking end timing of separation (see FIG. 9). On the other hand, the outer peripheral surface of the rotating plate 52 is in contact with the first outer peripheral surface 51 a of the outer peripheral surface of the stopper member operation cam 51 from the above-described kicking end timing to the next kicking start timing. (See FIG. 10).

  In the stopper member operation cam 51, when the first outer peripheral surface 51 a abuts on the outer peripheral surface of the rotating plate 52, the rotating plate is compared with the case where the second outer peripheral surface 51 b contacts the outer peripheral surface of the rotating plate 52. 52 can be moved closer to the paper sheet P. Therefore, when the second outer peripheral surface 51 b of the stopper member operation cam 51 is in contact with the outer peripheral surface of the rotating plate 52, the stopper rubber 50 b of the stopper member 50 in the direction toward the paper sheet P is the outer periphery of the kicker roller 10. On the other hand, when the first outer peripheral surface 51a of the stopper member operation cam 51 is in contact with the outer peripheral surface of the rotating plate 52, the stopper rubber of the stopper member 50 in the direction toward the paper sheet P. 50b moves forward from the outer peripheral surface of the kicker roller 10.

Next, the operation of the present embodiment having such a configuration will be described.
First, an operation for sequentially feeding a plurality of sheets in a stacked state to the outside one by one will be described.

First, a plurality of paper sheets are placed between the bill holding member 40 and the kicker roller 10 on the placing table 45. Then, by moving the bill presser member 40 forward toward the kicker roller 10 (by moving it to the right side in FIG. 1), a plurality of paper sheets are sandwiched between the bill presser member 40 and the kicker roller 10. The paper sheet is placed in a standing position.
A force is applied from the rear to the bill holding member 40 so as to always advance toward the kicker roller 10 on the mounting table 45, and some of the paper sheets in the stacked state are fed by the kicker roller 10. Even when kicked out, the remaining paper sheets can always be maintained in a standing position.

  After stacking a plurality of paper sheets in a standing position by the bill holding member 40, the kicker roller 10 and the feed roller 20 are continuously rotated in the directions of the arrows in FIG. At this time, the stopper member operation cam 51 whose center is attached to the shaft of the kicker roller 10 also rotates continuously in synchronization with the kicker roller 10.

As the kicker roller 10 continuously rotates, the foremost paper sheet P among the plurality of paper sheets in the stacked state comes into contact with the rubber member 12, and the foremost paper sheet P kicks downward. Is issued.
Here, from the kicking start timing at which the rubber member 12 of the kicker roller 10 starts to contact the frontmost paper sheet P, the frontmost paper sheet P is kicked out and separated from the rubber member 12. Until the ejection end timing, the outer peripheral surface of the rotating plate 52 pivotally supported by the stopper member 50 comes into contact with the second outer peripheral surface 51b of the stopper member operation cam 51 (see FIG. 9). Therefore, the stopper rubber 50b of the stopper member 50 is retracted from the outer peripheral surface of the kicker roller 10 in the direction toward the paper sheet P, and the foremost paper sheet P is locked by the stopper member 50. Absent.

  On the other hand, after the foremost paper sheet P is kicked out by the rubber member 12 of the kicker roller 10, the stopper member is used until the kicker roller 10 further rotates and the rubber member 12 comes into contact with the next paper sheet. The outer peripheral surface of the rotating plate 52 pivotally supported by 50 abuts on the first outer peripheral surface 51a of the stopper member operation cam 51 (see FIG. 10). For this reason, the stopper rubber 50b of the stopper member 50 is advanced from the outer peripheral surface of the kicker roller 10 in the direction toward the paper sheet P, and the next paper sheet is locked by the stopper member 50. It is possible to reliably prevent a plurality of paper sheets from being double fed.

  Further, as shown in FIG. 3 and FIG. 4, the boundary portion 15 between the base portion 11 and the rubber member 12 on the outer periphery of the kicker roller 10 is substantially between the central portion 11 b of the base portion 11 and the rubber member 12. Therefore, the vibration of the paper sheet P generated when the rubber member 12 starts to contact the foremost paper sheet P in the accumulated state can be reduced. On the other hand, since there is a step between the end portion 11a of the base portion 11 and the rubber member 12 at the boundary portion 15, an edge effect can be reliably obtained when the paper sheet P is kicked out by the rubber member 12. .

  In this way, a plurality of paper sheets that are stacked on the mounting table 45 can be intermittently kicked sequentially one by one by the kicker roller 10 to the subsequent feed roller 20.

  The paper sheets kicked downward by the kicker roller 10 are sent to a gate portion G (nip) formed between the rubber member 22 of the feed roller 20 and the rubber member 32 of the pressure roller 30. This gate portion The paper sheets sent to G are fed out one by one by the feed roller 20. At this time, since the pressure roller 30 is provided so as to be in pressure contact with the feed roller 20, if there is no paper sheet between the feed roller 20 and the pressure roller 30, the pressure roller 30 has a torque higher than the set torque. Torque is applied, and the pressure roller 30 rotates with the feed roller 20 and rotates in the direction of the arrow in FIG. On the other hand, when one or more sheets are sandwiched between the feed roller 20 and the pressure roller 30, only a torque smaller than the set torque is applied to the pressure roller 30. For this reason, the pressure roller 30 is a torque limiter. The rotation is forcibly stopped by. As a result, only one paper sheet that is in contact with the feed roller 20 is fed out by the rotation of the feed roller 20, and the conveyance of the plurality of paper sheets at the gate portion G is suppressed.

Here, as shown in FIG. 7 and FIG. 8, the feed roller 20 has flanges 23 protruding outward in the radial direction from the rubber member 22 on both sides, so that the paper sheets are formed in the gate portion G. The resistance at the time of entering can be increased, and a plurality of paper sheets can be further reliably prevented from being fed at the gate portion G. Further, since the flange 23 protrudes further outward in the radial direction than the rubber member 22, even when the paper sheet sent to the gate portion G is an abnormal paper sheet such as a paper sheet with a folded tip. In the gate portion G, no conveyance failure occurs.
The paper sheets discharged from the gate portion G between the feed roller 20 and the pressure roller 30 are further conveyed by the first grip roller 25 and the second grip roller 26 along the guide member 29, and finally the third sheet. It is carried out from the nip between the grip roller 27 and the carry-out roller 28.

  Next, the operation of storing a plurality of sheets sequentially fed from the outside and putting them in a stacked state will be described for the sheet storage and feeding device of the present embodiment.

  First, a sheet is inserted one by one between the third grip roller 27 and the carry-out roller 28, and the inserted sheet is a gate between the feed roller 20 and the pressure roller 30 along the guide member 29. Sent to part G. Here, the feed roller 20 continuously rotates in the opposite direction to the arrow direction in FIG.

  Sheets fed to the gate part G are fed one by one by the feed roller 20. At this time, since the pressure roller 30 is provided so as to be in pressure contact with the feed roller 20, a stable grip force can be obtained in the gate portion G. Further, since the one-way clutch is used as the holding portion for holding the pressure roller 30, the pressure roller 30 can freely rotate without being affected by the torque limiter when the paper sheet is fed. The pressure roller 30 functions as a pinch roller.

The paper sheets fed by the feed roller 20 are sequentially fed onto the mounting table 45. Then, the plurality of paper sheets fed and accumulated on the mounting table 45 are brought into an upright state by being sandwiched between the bill pressing member 40 and the kicker roller 10.
At this time, the feed roller 20 has flanges 23 protruding outward in the radial direction from the rubber member 22 on both sides of the rubber member 22, so that the paper sheets are stored when the paper sheets are stored. When passing through the gate portion G, for example, a cross-sectional shape curved into a waveform is formed, and a stiffness can be added to the paper sheets. For this reason, when the paper sheets are stacked on the mounting table 45, it is possible to stably stack the paper sheets by adding the stiffness to the sent paper sheets.

  As described above, according to the paper sheet storage and feeding device of the present embodiment, the rubber member (high friction portion) 12 is formed on a part of the outer periphery of the base portion 11 in the kicker roller 10 and the feed roller 20. In this embodiment, a rubber member (high friction portion) 22 is formed on the entire outer periphery of the base portion 21, and a pressure contact type gate portion G that separates the sheets fed by the feed roller 20 one by one is fed to the feed portion 20. The roller 20 and the pressure roller 30 are configured. As a result, the stacked paper sheets can be surely kicked out one by one by the kicker roller 10 without being affected by the thickness or stiffness of the sheets, and then the pressure-contact type gate portion G is formed. By letting it pass through, it is possible to reliably carry out the sheets one by one without being affected by the thickness of the paper sheet and the strength of stiffness. For this reason, it is not necessary to adjust the gate portion for a plurality of types of paper sheets having various thicknesses and stiffness, for example, banknotes of various countries, and without causing double feeding of the paper sheets. It is possible to reliably feed out one sheet at a time, and as a result, it is possible to reliably measure the number of sheets to be fed out.

  In addition, according to such a paper sheet storage and feeding device, the paper sheet can be fed out on the same conveyance path as that of the paper feeding, so that the paper sheet storage and feeding device is made small. Can do.

  In the present embodiment, the paper sheet storing and feeding device for feeding and unloading paper sheets has been described. However, the present invention is not limited to this, and the paper sheets are fed and stored. The present invention can be applied to a paper sheet feeding device that does not have a function to perform and only sequentially feeds paper sheets to the outside one by one.

Moreover, the paper sheet storing and feeding device according to the present invention is not limited to the above-described aspect, and various changes can be made.
Next, a modified example of the paper sheet storing and feeding device according to the present invention will be described with reference to FIGS. 11 and 12, the same parts as those in the embodiment shown in FIGS. 1 to 10 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 11, in the vicinity of the kicker roller 10, the upper end of the foremost paper sheet P among the plurality of paper sheets stacked on the mounting table 45 is pressed rearward (left side in FIG. 11). In addition, a movable slope member (pressing member) 60 for maintaining these paper sheets in a standing state may be provided. Note that the pressing member that presses the upper end of the foremost paper sheet P on the mounting table 45 backward is not limited to the movable slope member 60 described above, and for example, a fixed type can be used. .

The lower end of the movable slope member 60 is pivotally supported in the vicinity of the shaft of the kicker roller 10, and extends from the lower end toward the paper sheet P upward (upper left direction in FIG. 11). And this movable slope member 60 can be rock | fluctuated in the left-right direction of FIG. 11 centering on the pivoted lower end part. Note that a force is applied to the movable slope member 60 by, for example, a spring member (not shown) so as to fall toward the paper sheet P (in the direction of the arrow in FIG. 11). Therefore, as shown in FIG. 11, the movable slope member 60 contacts the upper end of the frontmost paper sheet P among the plurality of paper sheets that are stacked on the mounting table 45, and this frontmost paper sheet. The upper end of the leaf P is pressed backward.
As shown in FIG. 11, a guide member 61 extending in the vertical direction is fixed in the vicinity of the kicker roller 10, and this guide member 61 faces the foremost sheet P. .

Next, the operation of this modified example having such a configuration will be described, but the description of the same operation as the embodiment shown in FIGS. 1 to 10 will be omitted.
When a paper sheet is fed out, when a plurality of paper sheets are first placed between the bill holding member 40 and the kicker roller 10 on the placing table 45, these paper sheets are completely standing. In some cases, the posture may be tilted forward toward the kicker roller 10 without being in a standing state. Further, while the paper sheets are carried out by the kicker roller 10, the paper sheets on the mounting table 45 are pushed forward (to the kicker roller 10 side) by the tag pressing member 40, but the lower end portion of the paper sheets and the mounting table. The friction between the surface 45 and the surface of the paper 45 may cause the paper sheets to fall forward from the standing position and to be in a forward leaning posture while being pushed out.
For this reason, a force is applied to the movable slope member 60 so as to fall to the paper sheet P side by the aforementioned spring member. As a result, the upper end of the foremost paper sheet P is pressed rearward by the movable slope member 60, and a plurality of paper sheets in a forward tilted position on the mounting table 45 are in a standing state.

  Next, when the kicker roller 10 is continuously rotated, the foremost paper sheet P among the plurality of paper sheets in the accumulated state comes into contact with the rubber member 12, and the foremost paper sheet P is It is kicked downward. In this way, a plurality of paper sheets that are stacked on the mounting table 45 are intermittently kicked sequentially one by one by the kicker roller 10 to the subsequent feed roller 20 (see FIG. 12). At this time, by providing the movable slope member 60 extending forward and upward toward the paper sheet P, a large gap (space) is formed between the paper sheet and the feed roller 20 as shown in FIG. Can be prevented, and it is possible to prevent the paper sheet from being fed in the gate portion G and the leading edge of the paper sheet from being folded.

Specifically, when the movable slope member 60 is not provided, the plurality of paper sheets on the mounting table 45 are inclined forward toward the kicker roller 10, so that A large gap is generated between the lower portion of the paper sheet and the feed roller 20, and the foremost paper sheet P kicked out by the kicker roller 10 is clogged in the gap and directly enters the gate portion G. It may not be sent. Further, the leading edge of the paper sheet P may be broken by this gap. On the other hand, by providing the movable slope member 60, as shown in FIG. 12, compared with the case where the above-mentioned movable slope member 60 is not provided, the lower part of the paper sheets on the mounting table 45 and The gap with the feed roller 20 can be reduced, and the paper sheet P can be prevented from being clogged or the leading edge of the paper sheet P broken at this gap.
Further, since the movable slope member 60 is inclined forward and upward with respect to the paper sheet P, this movable slope member is also used when the paper sheet P is kicked out by the kicker roller 10 and sent to the gate portion G. Only the upper end portion of the paper sheet P contacts the member 60.

  As described above, according to the paper sheet storing and feeding device of the present modification, the movable slope member (pressing member) 60 pushes the upper end of the frontmost paper sheet P backward to stand these paper sheets. Therefore, the gap generated between the lower part of the foremost sheet P and the feed roller 20 can be reduced, and the sheet P kicked out by the kicker roller 10 can be reduced. It is possible to prevent clogging in this gap and the leading edge of the paper sheet P from being bent in this gap. Further, since only the upper end portion of the frontmost paper sheet P contacts the movable slope member 60, the surface of the frontmost paper sheet P is not subjected to a large guide resistance by the guide member 61. It is possible to prevent the paper sheet from being fed in the gate portion G.
