Description

  The present invention, for example, for paper sheets that stacks banknotes from a conveyance path to a stacking unit by a stacking process such as a deposit process and feeds banknotes from the stacking unit to the transport path by a feeding process such as a withdrawal process. The present invention relates to a paper sheet stacking and feeding device that performs stacking processing and feeding processing.

  2. Description of the Related Art Conventionally, as a banknote stacking and feeding device that stacks and feeds banknotes necessary for ATM, for example, an impeller 91 formed of a rubber material is provided in the vicinity of a stacking port that transports banknotes and discharges them to a stacking section. There has been proposed a banknote stacking and feeding device 1 ′ that acts sometimes and retracts during feeding processing (see, for example, Japanese Patent Application No. 2001-368334).

  The structure and operation of the banknote stacking and feeding apparatus 1 ′ will be briefly described with the right side cross-sectional views shown in FIGS. 10 and 11.

  At the time of the stacking operation in which the banknote stacking and feeding apparatus 1 ′ stacks the banknotes 2, as shown in FIG. 10, the feed roller 31 is rotated in the stacking direction (counterclockwise in the drawing), and the banknotes 2 are transported by the rotational force. 51 to transport. At this time, the impeller 91 is rotating in the accumulation direction (clockwise in the drawing), and the wing 91a is spread by the centrifugal force of the rotation. For this reason, when the banknote 2 transported through the transport path 51 is discharged into the accumulation space 3, the wing 91a knocks down the banknote 2 and the banknote 2 is smoothly stacked on the lifting plate 11.

  When the banknote stacking and feeding device 1 'feeds out the banknote 2, the pickup rotating body 61 is controlled to pivot downward as shown in FIG. 11, and rotated in the feeding direction (counterclockwise in the drawing). The bill 2 is fed out to the transport path 51. At this time, the impeller 91 is stopped without rotating and is in a storage state (equivalently in a retracted state) in which the blade 91a is closed. For this reason, when the feed roller 31 is rotated in the feeding direction (clockwise in the drawing) and the banknote 2 is transported by the transport path 51 by the rotational force, the wing 91a does not prevent the banknote 2 from being fed out and transported. Yes.

  In this way, the banknote stacking and feeding apparatus 1 ′ omits the mechanism for controlling the vertical movement of the impeller itself, which is necessary for the type in which the impeller is formed of an old plastic film, thereby reducing the cost.

  However, in the banknote stacking and feeding apparatus 1 ′ such as ATM, which frequently performs the stacking operation and the feeding operation, the impeller 91 is overworked. If the use is continued, the rubber material is plastically deformed. The wing 91a will open. For this reason, the wings 91a come into contact with the banknote 2 fed out from the transport path 51, causing a paper jam.

  Further, since the wing 91a is curved so that the intermediate portion between the tip portion and the base on the rotating shaft side precedes at the time of stacking, the contact angle between the wing 91a and the bill 2 when the bill 2 is knocked down becomes loose. It was not possible to sufficiently act on the banknote 2 (hereinafter, abbreviated as a deformed bill) having deformation such as folding.

  In view of the above-mentioned problems, the present invention proposes a paper sheet stacking and feeding device that sufficiently acts on a deformed bill during stacking and does not hinder feeding regardless of plastic deformation during feeding. The purpose is to reduce the maintenance and extend the continuous operation time of the paper sheet stacking device, and to realize a total cost reduction such as production cost and operation cost.

The present invention relates to an accumulating unit for accumulating paper sheets, a feed roller provided at the entrance of the accumulating unit, a gate roller facing the feed roller, and a blade having a wing provided coaxially with the gate roller. A paper sheet stacking / feeding device comprising: a wheel, wherein when the paper sheets are stacked on the stacking unit, an intermediate part of the wing is rotated by the impeller from a base part and a tip part of the wing. The wings are curved in the direction of retreat, and the wings are paper sheet stacking and feeding devices that knock down the paper sheets discharged to the stacking section.

The present invention is also provided with a stacking unit for stacking paper sheets, a feed roller for transporting paper sheets to the stacking unit, a gate roller facing the feed roller, and coaxial with the gate roller. A paper sheet stacking / feeding device comprising: an impeller having a blade wheel, wherein when the paper sheets are stacked on the stacking unit, the wings are curved at the tip side toward the stacking direction of the paper sheets. and has a feature in that the paper sheet is discharged to the stacking unit beyond the said gate roller and said feed roller, a paper sheet storing and feeding device for integrated on an integrated pre sheet To do.

  According to the present invention, it is possible to provide a high-performance paper sheet stacking and feeding device that prevents clogging in the stacking process and the feeding process and executes stacking and feeding smoothly. In addition, it is possible to reduce the maintenance cost by extending the usable period of the rotating member and to reduce the overall cost. In particular, due to the curved shape of the wings, it can be struck firmly at a narrower angle than when it is bent straight or in the opposite direction.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
First, the external appearance and structure of the banknote stacking and feeding apparatus 1 will be described together with a perspective view of the banknote stacking and feeding apparatus 1 shown in FIG.

In the description, the rotation in the stacking direction and the rotation in the feeding direction are, for example, a stacking unit on the right side when viewed from the right side, a transport unit on the upper left side, and a rotating member on the lower left side of the connection unit between the transport unit and the stacking unit If it is, clockwise (stacking direction) during integration, when feeding means to rotate in the counterclockwise (feeding direction).

  The banknote stacking / dispensing device 1 has a box-like outer shape, and has a stacking space 3 in which banknotes 2 are horizontally stacked. A lifting / lowering plate having a large banknote (sized as a banknote) is provided at the bottom of the stacking space 3. 11 is provided.

Here, the “banknote” is an example of the “paper sheet” of the present invention, and the “paper sheet” includes a card, paper, and printed paper.
The elevating plate 11 is guided so as to move up and down along the side wall in a horizontal state. A part of the elevating belt 13 is fixed to the elevating plate 11 by a fixing portion 12, and the elevating belt 13 is rotated forward and backward by forward / reverse control of the forward / reverse rotation motor (pulse motor) 14 by an appropriate control means. The vertical movement of the lift plate 11 is controlled.

  On the upper part of the banknote stacking and feeding apparatus 1, a feed shaft 32 is installed in a horizontal direction and supported, and two substantially cylindrical feed rollers 31, 31 are inserted into the feed shaft 32 at a predetermined interval. The feed roller 31 conveys the banknotes 2 to the back side during stacking and upwards during feeding.

  A gear 34 is inserted into one end (right end in the drawing) of the feed shaft 32, and the rotational force of the forward / reverse motor 41 is used as a driving force via a gear 42 fixed to the gear 43 and the forward / reverse motor 41. obtain. The forward / reverse motor 41 performs forward / reverse control by appropriate control means.

  A gear 33 is inserted into the other end (the left end in the drawing) of the feed shaft 32, and a driving force is transmitted via the gear 24 to the shaft 22 that is installed under and in front of the feed shaft 32. .

  The shaft 22 is provided with two gate rollers 25, 25 facing the feed rollers 31, 31, so that the circumferential surface can slightly enter grooves formed in the feed rollers 31, 31. A convex shape is formed, and the feed roller 31 and the gate roller 25 are overlapped with each other. Here, the gate roller 25 has a structure that rotates in the stacking direction during stacking and stops without rotating during unwinding.

  Centrifugal impellers 21 and 21 are provided on the outside of the gate rollers 25 and 25 described above for knocking down bills during stacking. As a result, the shaft 22 functions as an impeller shaft that is the axis of the centrifugal impeller 21.

  As will be described later, the centrifugal impeller 21 is formed of an appropriate rubber material so that the wings 21a are stored in a non-rotating stationary state and the wings 21a are spread by centrifugal force due to rotation (rotation operation). Yes.

The centrifugal impeller 21 has a structure that rotates in the accumulation direction during accumulation, and rotates in the extension direction when fed out. Details of these structures will be described later.
The centrifugal impeller 21, the shaft 22, and the gate roller 25 constitute an integrated feeding auxiliary device 20 (described later).

  One end (right end in the drawing) of the shaft 22 is supported by the positioning plate 44 outside the accumulation space 3, and the end portion (right end in the drawing) together with the feed shaft 32 that is also supported by the positioning plate 44. ) Is positioned.

  With the above configuration, the banknote 2 can be transported by the transporting force of the feed roller 31 and the gate roller 25, the banknote 2 can be stacked in the stacking space 3 during stacking, and the banknote 2 can be fed out of the transport path during unwinding. Can do. During this accumulation / feeding operation, the centrifugal impeller 21 also acts as an operation aid.

  Next, the structure of the accumulation / feeding auxiliary device 20 will be described together with an exploded perspective view of the accumulation / feeding auxiliary device 20 shown in FIG.

  The stacking and feeding auxiliary device 20 is formed of a metal member so that the central coupling portion 23, the gate rollers 25 and 25 on both sides thereof, and the outer gear 26 of the left gate roller 25 rotate together. Each is inserted into the shaft 22. The E-ring 27, which is a washer-shaped fastener, is fitted into the retaining groove 22a of the shaft 22 so as to sandwich both sides of the gate portion 20a formed by the coupling portion 23, the gate roller 25, and the gear 26, and the gate portion 20a is Position.

  Centrifugal impellers 21 and 21 are inserted and fixed to a further outer portion of the gate portion 20 a of the shaft 22.

  The integrated feeding auxiliary device 20 assembled in this way has a structure as shown in the front view of FIG. 3 and the cross-sectional view of FIG. 4, and the gate portion 20a operates integrally.

  That is, the side surface of the gate roller 25 is provided with an engagement hole (recessed portion) as shown in FIG. 4, and the engagement protrusions 23a and 26a provided on the side surface of the coupling portion 23 and the gear 26 are provided in the engagement. Each of them is connected with fitting holes. As a result, none of the connected components can rotate alone, but rotate / non-rotate integrally as the gate portion 20a.

  A one-way clutch 23b is provided inside the coupling portion 23. The one-way clutch 23b is in a non-rotating state with respect to the shaft 22 in the accumulation direction, that is, rotates integrally with the shaft 22, and is free with respect to the shaft 22 in the feeding direction. Become free.

  A one-way gear 28 is connected to the gear 26 at a lower position. The one-way gear 28 is rotated by the gear 28a formed on the outer peripheral surface thereof meshing with the gear 26 described above. The one-way clutch 28b accommodated inside stops the rotation in the feeding direction and rotates in the accumulation direction. The directionality of the clutch is set so as to allow, and the clutch is supported on the fixed shaft 29 a of the fixing portion 29. The fixing portion 29 is fixed to a guide plate 52 (described later) of the conveyance path.

  With this structure, the one-way gear 28 allows the rotation of the gate rollers 25, 25 in the stacking direction and stops it as non-rotating in the feeding direction.

  As a result, in the accumulation / feeding auxiliary device 20, all components are rotated by the shaft 22 during accumulation, and the centrifugal impeller 21 and the shaft 22 are rotated at the time of dispensing, but the gate portion 20 a is not rotated (that is, stopped). It becomes.

  With the above structure, during the accumulation operation, the gate portion 20a and the centrifugal impeller 21 rotate to provide accumulation assistance. At the time of feeding, the gate portion 20a stops and gives a frictional force so as not to feed the second and subsequent sheets from the top of the banknotes 2 stacked in the stacking space 3. At the time of feeding, the centrifugal impeller 21 rotates in the feeding direction to perform feeding assistance.

Next, the shape and function of the centrifugal impeller 21 will be described together with the explanatory view of the centrifugal impeller 21 shown in FIG.
(A) in the figure shows a perspective view of the centrifugal impeller 21 in a stationary state, and (B) shows a perspective view of the centrifugal impeller 21 in a rotating state.

  The centrifugal impeller 21 is integrally formed of a rubber material into a shape provided with wings 21a at four equal positions on the side surface of the cylindrical body 21b as shown in FIG.

  The wing 21a has a shape in which an arcuate base portion 21c having a small radius is connected to one end of an arcuate intermediate portion 21d, and is formed in a reverse taper shape in which the thickness gradually increases from the base portion 21c on the cylindrical body 21b side to the tip end portion 21e. is doing.

  When the centrifugal impeller 21 formed in this way is rotated in the positive direction (stacking direction), the wings 21a spread by centrifugal force as shown in (B), and the radial distance 21f between the tip and the rotating shaft becomes longer. . At the time of this rotation, since the wing 21a is formed in a reverse taper shape as described above, the tip 21e side is heavy and the wing 21a is likely to spread.

  Further, when the centrifugal impeller 21 is rotated in the reverse direction (feeding direction), the wings 21a are easily spread as in the case where the centrifugal impeller 21 is rotated in the forward direction.

  With the above shape, when the centrifugal impeller 21 rotates in the stacking direction as indicated by the arrow direction of the phantom line, the banknote 2 is hit with the inner side surface or the front end portion 21e of the intermediate portion 21d. The tapping force at this time becomes a strong force by acting in the direction in which the urging force of the rubber material to return to the original shape is also tapped.

  On the other hand, when it is rotating in the feeding direction which is reverse rotation, the banknote 2 is struck (or stroked or pushed out) by the outer surface or the front end portion 21e of the intermediate portion 21d. The tapping force at this time is weak because the biasing force of the rubber material returning to its original shape works in the opposite direction.

  In this manner, the hitting operation includes an operation of hitting the bill 2 with the tip 21e or / and the intermediate portion 21d of the wing 21a.

  The wing is pivoted at a resin member such as a deformable rubber member, a deformable metal member such as a deformable elastic iron plate, a base part on the rotating shaft side and / or an intermediate part between the base part and the tip part. A deformable structure that can be bent or bent in the rotation direction, or a stretchable member that can expand and contract in the radial direction of the rotation axis is included.

  The wing includes a curtain-like body formed to have a predetermined width, thickness, and length, or a string-like body formed to a predetermined thickness. For curtains, a fixed shape with a constant width, thickness, and length, a taper that increases in thickness toward the tip, a taper that increases in width toward the tip, and a weight on the tip In other words, it is formed in the shape of the center of gravity of the tip. Further, the string-like body includes a fixed shape having a constant thickness, a taper shape in which the thickness increases toward the tip, and a tip center of gravity with a weight on the tip side.

  Next, together with the right side cross-sectional view of the banknote stacking and feeding device 1 shown in FIG. 6 and the right side cross-sectional view of the banknote stacking and feeding device 1 shown in FIG. The operation of will be described.

  First, in FIG. 6 and FIG. 7, the banknote stacking and feeding apparatus 1 includes the feed roller 31 described above together with FIG. 1 on the upper front side, and a belt 62 is attached to pulleys 63 and 64 behind the feed roller 31. A tension pickup rotary body 61 is provided.

  The pick-up rotating body 61 swings up and down around the pulley 64 on the back side during the stacking operation and the feeding operation, and contacts the stacked banknotes 2 during the feeding and sends it out in the feeding direction. It is configured to be driven by appropriate driving means.

  A transport path 51 for transporting banknotes is a guide plate 53 that guides the top, front, and bottom at a position slightly inside the outer periphery of the feed roller 31 and extends horizontally rearward as it is, and the top end of the banknote stacking and feeding device 1. The guide plate 52 is formed by a guide plate 52 that extends right below the banknote outlet 54, partially curves along the outer periphery of the feed roller 31, and then extends right below again.

The guide plate 52 is screwed with the fixing member 29 (not shown) described with reference to FIG.
Further, in the vicinity of the connecting portion 3a between the conveyance path 51 and the accumulation space 3, the above-described accumulation feeding auxiliary device 20 (that is, the gate portion 20a and the centrifugal impeller 21) is disposed.

  A banknote slot 55 is provided slightly behind the banknote outlet 54, and the banknote slot 55 and the banknote outlet 54 are integrated inside and connected to the transport path 51.

With the above configuration and structure, the following operations are performed during integration and during delivery.
At the time of stacking, the banknotes 2 carried in from the banknote insertion slot 55 are transported through the transport path 51 by the transporting force of the feed roller 31, discharged into the stacking space 3, and stacked on the lifting plate 11.

  At the time of this accumulation, as shown in FIG. 6, the banknotes 2 are knocked down by the blades 21 a of the centrifugal impeller 21 rotating in synchronization with the feed roller 31, and the banknotes 2 that are successively conveyed collide with each other in the accumulation space 3. Prevents clogging.

  At this time, the gate roller 25 rotates together with the centrifugal impeller 21 together with the shaft 22 by the action of the one-way clutch 23b described above, and the one-way gear 28 enters a free state to allow the rotation.

  At this time, the pickup rotator 61 is in a raised state so as not to prevent the banknotes 2 from being stacked.

At the time of feeding, the pickup rotating body 61 is lowered as shown in FIG. 7, and the stacked banknotes 2 are picked up and sent out to the transport path 51.
At this time, the feed roller 31 and the centrifugal impeller 21 are synchronously rotated in the reverse direction from the time of accumulation, and the gate roller 25 becomes free from the shaft 22 by the action of the one-way clutch 23b described above, and by the action of the one-way gear 28. It has stopped.

  Thus, the centrifugal impeller 21 feeds the banknote 2 fed out to the transport path 51 so as to help the banknote 2 being fed out. Further, the gate roller 25 is stopped, and the second and subsequent banknotes 2 are prevented from being taken out by a frictional force.

  The feeding assisting operation includes an operation of rotating the centrifugal impeller 21 in the feeding direction at the same speed as the feeding speed, so that the wing 21a contacts the bill 2 and does not disturb the feeding, or touches to assist the feeding. included.

  In this way, with a simple structure using the centrifugal impeller 21, the banknotes 2 can be smoothly stacked / delivered, clogging can be prevented, and performance can be improved.

  Further, as shown in the front view of FIG. 8, the centrifugal impeller 21 is located outside the feed roller 31 and the gate roller 25, and urges the bill 2 upward at the time of stacking and feeding. The action of pulling outward (both sides) to stretch the folds and bends can also be obtained. Thereby, clogging due to old bills sagging between the feed rollers 31, 31 can be effectively prevented.

  Furthermore, as shown in the explanatory view of FIG. 9, there is an effect of smoothly collecting / unpaying the deformed bills. That is, when stacking folded banknotes 2 as shown in (C), the wing 21a is curved straight or in the opposite direction due to the shape in which the intermediate part 21d is curved backward from the tip part 21e. Can be knocked down firmly at a narrow angle.

The tapping force at this time is a force obtained by adding the elastic force of the wings 21a to the centrifugal force, and a strong tapping force that can sufficiently cope with the deformed bill is obtained.
As a result, when the banknotes 2 folded upward at the end as shown in the figure are stacked, it is possible to prevent the next banknote 2 from hitting the folded portion and jamming.

At the time of feeding, a deformed bill (banknote 2) whose feeding side is deformed as shown in (D) can be fed out smoothly. In other words, if the feeding side is deformed as shown in the figure, it will be completely folded between the feed roller 31 and the gate roller 25 in the conventional case, resulting in a thickness equivalent to two bills and not clogging the overlap part. However, by carrying the banknote 2 in the feeding direction so that the wings 21a are stroked from below, the bent deformed portion can be extended and fed out straight.
At this time, since the centrifugal impeller 21 rotates at the same speed as the feeding speed of the banknote 2, the feeding is not hindered even if the conveying force is not obtained.

  As described above, not only the normal banknote 2 but also the banknote 2 with deformation or breakage can be dealt with widely, and it is possible to prevent clogging and reduce maintenance personnel. Moreover, even if the centrifugal impeller 21 is in a state where the blades 21a are opened more than the time of manufacture due to plastic deformation, the accumulation and feeding performance of the banknotes 2 is not hindered and the accumulation and feeding performance is maintained for a long period of time. can do.

Although the centrifugal impeller 21 is provided on each of the left and right sides of the shaft 22, a plurality of centrifugal impellers 21 may be provided.
Further, the blades 21a of the centrifugal impeller 21 are not limited to four but may be formed by a plurality or one.

  Further, the shape of the wing 21a may be formed straight without being curved. In this case, even if it is not rotated, it is slightly drooped by gravity in a spread state, but it can be used without any problem because it acts by rotating both during accumulation and during feeding.

Further, the rubber material forming the centrifugal impeller 21 may be a hard rubber material or a soft rubber material, but it is desirable to form the rubber material in consideration of wear.
The wings 21a may be made of a hard rubber material so as to have a cavity or a soft part inside. Thereby, it can be set as the structure provided with abrasion resistance and a softness | flexibility.
