Description

  The present invention relates to a paper sheet stacking and separating apparatus that stacks and stores paper sheets such as banknotes and checks conveyed one by one and separates the stored paper sheets one by one.

For example, Japanese Patent Laid-Open No. 2001-240294 (Patent Document 1) is an example of a stacking / separating apparatus that stacks paper sheets that are conveyed one by one and separates the stacked paper sheets from the same opening as when stacking.
In this Patent Document 1, an accumulation space surrounded by guides and accumulated paper sheets is vacated at a portion where the paper sheets enter during paper sheet accumulation, and the paper sheets are conveyed to the accumulation space.

In this paper sheet stacking and separating apparatus, in order to stably stack paper sheets, the stacking space has a substantially triangular shape so that the entrance side into which the paper sheets enter is wide and narrows toward the front. . Further, a sheet roller provided with an elastic body in a brush shape rotates in the vicinity of the entrance where the paper enters, and the trailing edge of the paper is scraped to the side of the accumulated paper, and the subsequent paper To avoid colliding with.
Further, at the time of paper sheet separation, a part of the guides constituting the stacking space is retracted so as not to come into contact with the paper sheet to be separated, and a roller for separating at the same time is exposed. A paper sheet is pressed against the roller, and the paper sheet is separated by a frictional force with the roller.

Japanese Patent Laid-Open No. 2001-240294

  However, in the above-mentioned Patent Document 1, for example, when handling paper sheets that are folded in a direction substantially perpendicular to the transport direction, the stacked paper sheets collide with the paper sheets transported later, and the paper sheets It may cause problems such as breakage or clogging.

  In addition, in the case of paper sheets having a thickness distribution in the paper surface due to the state of printing or watermark, when the paper sheets are stacked in the same direction, the thickest part is the highest at the top of the stacked paper sheets, The thin part is inclined to become lower. When separating the inclined paper sheets, if the paper sheets are pressed against the separating roller, the pressing force to each roller becomes uneven, and the higher the paper sheet, the higher the pressing force is. The portion also has a smaller pressing force, and the sheets are separated obliquely so that the side with the higher pressing force precedes. The skewed paper sheets may cause a decrease in the recognition rate of paper sheets and jams during conveyance.

  An object of the present invention is to provide a paper sheet stacking / separating mechanism capable of stably stacking folded paper sheets and reducing skew during separation.

  The purpose is to provide a bottom plate on which banknotes are deposited, an entrance / exit part where the banknotes enter / exit, a first wall surface having the entrance / exit part, a second wall surface having a position facing the first wall surface, In a paper sheet stacking / separating apparatus comprising a roller for feeding out the banknote from an entrance and a guide provided along the banknote conveyed by the roller, the surface of the guide and an extension line of the first wall surface This is achieved by the guide having a portion protruding from a straight line connecting the intersection, the surface of the guide, and the intersection of the second wall surface.

  In addition, the above-mentioned object is that the guide is divided into two or more, the first guide is provided so as to be rotatable in the vicinity of the entrance, the second guide has the protruding portion, and the first guide This is achieved by changing the amount of protrusion of the protruding portion by turning the second guide relative to the first guide.

  Further, the object is to provide a roller at a position in contact with the paper sheets accumulated on the projecting portion of the second guide, and the roller is applied to the paper sheets with a predetermined pressing force when separating the paper sheets. This is achieved by pressing the second guide against the accumulated paper sheet side with an elastic body so as to come into contact.

  According to the present invention, it is possible to provide a small paper sheet stacking / separating apparatus that can stack even folded banknotes and the like without any obstacles and can reduce skew during separation.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

First, it demonstrates using the cash automatic transaction apparatus installed in a financial institution etc. which is an example to which this invention is applied.
FIG. 1 is a perspective view showing an example of an automatic teller machine.
In FIG. 1, inside the automatic teller machine 100, a user inserts a banknote (deposits) or releases a banknote to a user (withdraws) a banknote handling apparatus 101 and a user's card. , A card / detail processing device 102 that prints and releases a transaction statement slip, a passbook processing device 103 that records transaction details in a passbook, and a user who displays operation guidance to the user and inputs an instruction from the user An operation unit 104 and a main body control unit 105 that monitors and controls each of the devices are included.

Here, an example of a paper sheet is a banknote, and the paper sheet handling apparatus 101 which handles a banknote is demonstrated below.
FIG. 2 is a side view showing the configuration of the bill handling apparatus 101 to which the present invention is applied.
In FIG. 2, the bill handling apparatus 101 temporarily stores the deposited bill until the transaction is established, and a deposit / withdrawal port 70 where the user inserts and removes the bill, a bill discriminating unit 71 that discriminates the bill. Monitor and control the storage 72, a deposit box 73 for storing banknotes for which transactions have been made upon deposit, a reflux warehouse 74 for both deposit and withdrawal, a banknote transport path 75 for transporting banknotes to the units, and the units. And a control unit 76.

  The deposit / withdrawal port 70 feeds the banknotes thrown into the customer one by one to the banknote transport path 75, and accumulates the banknotes transported from the banknote transport path 75 and discharges them to the users. In the banknote discrimination | determination part 71, the optical magnetic characteristic of the banknote conveyed by the banknote conveyance path 75 is measured, and a money type, authenticity, etc. of a conveyance banknote are discriminate | determined.

  The temporary storage 72 is a part for temporarily storing the conveyed banknotes. For example, the banknotes deposited by the user are temporarily stored, and when the customer accepts the transaction, the banknotes are stored in the safe 73 and the return box 74. If not accepted, the banknote is conveyed to the deposit / withdrawal port 70 and the actual product is returned to the customer. The deposit safe 73 is a safe for storing the banknotes that are transported, and stores banknotes that are not suitable for handling by the apparatus, such as banknotes that are only deposited, banknotes that are cut or broken, and banknotes that are skewed and transported. The reflux warehouse 74 has a stacking and separating device that stores banknotes thrown in by a customer, feeds the stored banknotes to the banknote transport path 75 in accordance with a transaction, and withdraws the money to the customers. The collection / separation device of the reflux box 74 according to the present invention will be described in detail later.

  FIG. 2 shows an example in which one safe box 73 and three return boxes 74 are mounted. However, these combinations are free and the number of mounting can be set freely. For example, a combination of two safe boxes 73 and two reflux boxes 74 may be used.

  The banknote conveyance path 75 includes, for example, a belt and a roller installed so as to sandwich a banknote, and a drive motor that drives the belt and the roller. Furthermore, there is a switching gate driven by an electromagnetic solenoid at the branch point of the banknote transport path 75, and the banknote transport direction can be switched. Therefore, by switching the rotation direction of the drive motor and the switching gate for each transaction operation, the bills pass through the bill discriminating unit 71 in both directions, and the deposit / withdrawal port 70, temporary storage 72, safe deposit box 73, reflux warehouse. It is conveyed between 74 each.

  The control unit 76 is connected to an actuator and a sensor such as a drive motor and an electromagnetic solenoid of each unit, and controls the actuator while monitoring the state of the sensor according to a transaction. Furthermore, it connects with the main body control part 105 of the automatic teller machine 100, controls the banknote handling apparatus 101 by the command from the main body control part 105, and reports the state of the banknote handling apparatus 101 to the main body control part 105.

Next, a conventional stacking / separating apparatus for the reflux box 74 according to the present invention will be described with reference to FIGS.
FIG. 3 is a side view showing a state when the reflux box 74 is accumulated, and FIG. 4 is a side view showing a state when the reflux box 74 is separated.

  3 and 4, the collection and separation device of the reflux container 74 includes a pickup roller 10, a feed roller 11, a gate roller 12, a bottom plate 13, a stack guide 14, a sheet roller 15, a back wall 16, The front wall 17, the pinch roller 18, and sensors are included.

  The pickup roller 10 and the feed roller 11 are made of a high-friction member such as rubber only at a part of the outer periphery, and the pickup roller 10 and the feed roller 11 are rotated, and a bill is conveyed by applying a frictional force at a constant cycle. Since the pickup roller 10 is power-connected to the feed roller 11 by a gear, the pickup roller 10 and the feed roller 11 rotate in the same direction and at the same speed. The feed roller 11 and the gate roller 12 are installed facing each other, and an overlap structure is formed in which the facing roller is inserted between the one roller. This is called an overlap part. The gate roller 12 has a structure incapable of rotating in the bill feeding direction, and rotates in the direction of the arrow a by the gear connection with the feed roller 11 at the time of stacking. The sheet roller 15 is a roller in which an elastic body is arranged in a brush shape. The sheet roller 15 does not rotate at the time of separation, and rotates in the direction of an arrow in conjunction with the gate roller 12 only at the time of accumulation. The bottom plate 13 is moved up and down in the directions of arrows b and c by the drive belt 13b, and moves up and down the banknotes 1 deposited thereon. As shown in FIG. 3, the stack guide 14 is inclined downward to conceal the pickup roller 10 during stacking. At the time of separation, as shown in FIG. 4, it pivots upward and retracts to serve as a transport guide. The front wall 17 and the back wall 16 are on the mouth side and the back side where bills to be conveyed enter and exit, and the bills are deposited between the front wall 17 and the back wall 16.

  Next, the operation of the collecting / separating device of the reflux container 74 will be described. First, the accumulation operation will be described. The stack guide 14 is lowered to a position where the pickup roller 10 is hidden, and the stacked banknotes 1 and the front wall 17 form a substantially triangular stacking space for transporting stacked banknotes. The banknotes transported from the banknote transport path 75 as indicated by the arrow A are sandwiched and transported by the feed roller 11, the pinch roller 18, and the gate roller 12 that rotate in the direction of arrow E and arrow G. The feed roller 11 and the gate roller It passes through the 12 overlapping portions and is thrown out between the back wall 16 and the front wall 17. At this time, the banknotes are thrown out along the stack guide 14 so that they do not interfere with the accumulated banknotes. The banknote thrown into the accumulation space collides with the back wall 16 and stops. At the same time, the trailing edge of the bill is struck down by the sheet roller 15 rotating in the direction of the arrow G. The bills conveyed in this way are collected.

Next, the separation operation will be described.
The bottom plate 13 is driven in the direction of arrow D, and the banknote 1 is brought into contact with the pickup roller 10 with a predetermined pressure. When the pickup roller 10 is rotated in the direction of the arrow, the bill is fed out to the overlap portion by the high friction portion of the pickup roller and the frictional force of the bill. At this time, since the uppermost banknote and the subsequent banknotes exert a frictional force between the banknotes, the subsequent banknotes are taken along with the uppermost banknotes and are drawn out in an overlapped state to reach the overlap structure. In the overlap portion, since the plurality of rollers are nested, the bill is deformed into a waveform. This deformation reaction force becomes a pressing force against the feed roller 11 and the gate roller 12, and a frictional force works. At this time, since the feed roller 11 is rotating in the direction of the arrow, the banknote in contact with the feed roller 11 is fed out as it is, and the banknote in contact with the stopped gate roller 12 stays. As a result, the banknotes are separated into one sheet, sandwiched between the pinch roller 18 and the feed roller 11, transported in the direction of arrow B, and transported to the banknote transport path 75.

  Here, when the conventional problems are arranged, in the conventional stacking and separating apparatus shown in FIG. 3, the cross section in the transport direction of the stack guide is substantially straight. For example, in the folded banknotes 2 and 3 shown in FIG. The banknotes 2 sometimes accumulated and the banknotes 3 transported to the stacking space collide with each other, causing damage such as breakage of the rear end of the banknotes 2 and the front end of the banknotes 3, and troubles such as banknote jamming.

  Further, when the bills are separated, they may be fed out at an angle due to an imbalance in the conveying force of the pickup roller 11 or the like. Largely skewed banknotes may not be correctly identified by the banknote discriminating unit 71, or may cause banknote jams during transportation.

Therefore, in the present invention, a stack guide as shown in FIGS. 6 to 8 is realized.
FIG. 6 is a perspective view of a stack guide according to an embodiment of the present invention.
FIG. 7 is a side view at the time of accumulation of the reflux cabinet in which the stack guide shown in FIG. 6 is mounted.
FIG. 8 is a side view at the time of separation of the reflux cabinet in which the stack guide shown in FIG. 6 is mounted.
6, 7, and 8, the stack guide 14 includes a stack guide base portion 14 b that can be rotated around the rotation center 11 s of the feed roller 11, and a stack guide base portion 14 b that is The banknote conveying surface is configured by the stack guide slide part 20 that can move in the direction, and the stack guide slide part 20 and the stack guide rotation part 30 that can be rotated by the rotation shaft 30s.

  The stack guide slide portion 20 is held on the stack guide base portion 14b by a rail guide, and a force is applied by the spring 22 so that the stack guide slide portion becomes longer. The stack guide rotation unit 30 is rotatably connected to the stack guide slide unit 20 via a rotation shaft 30 s, and a force that separates the stack guide rotation unit 30 from the stack guide slide unit 20 is applied by a spring 31. There is a guide roller 21 for contacting the back plate 16 at the tip of the stack guide slide portion 20.

  As shown in FIG. 7, the stack guide rotating unit 30 is provided with a protrusion 30a in the transport direction cross section on the surface of the stack guide with respect to the transport direction to narrow the back side of the accumulation space. By doing in this way, the folded banknote 2 can be hold | suppressed effectively and the collision of banknotes can be reduced.

  Further, since the protruding portion 30a rotates about the shaft 30s and is pressed downward by the spring 31, as shown in FIG. 8, when the bottom plate 13 operates to raise the bill 1 during separation, the protruding portion 30a Is pushed by the banknote 1 and the spring 31 is deformed so that the protrusion 30a can be retracted. Furthermore, the banknote skew feeding prevention roller 32 was provided in the position which the banknote of the protrusion part 30a contacts.

  As shown in FIG. 9, when the conveying force A of the pickup roller 10 is not uniform, a force for rotating the bill is generated. On the other hand, when the bill skew feeding prevention roller 32 is brought into contact with a predetermined force, the bill skew feeding prevention roller 32 receives a force B from the bill 1 to be rotated, and the bill skew feeding prevention roller 32 is restricted in the axial direction. Since the force C is generated as a reaction, the skew of the bills can be reduced by the balance between the force B and the force C.

  Since the force C depends on the friction between the banknote skew prevention roller 32 and the banknote 1, the outer periphery of the skew prevention roller 32 is preferably a high friction member such as rubber because the resistance force to prevent the skew is greater. Furthermore, since the banknote skew prevention roller 32 is freely rotatable in the banknote separating direction, it does not become an obstacle to the separation.

  Moreover, although the form which mounted the banknote skew feeding prevention roller 32 in the protrusion part 30a was shown in FIGS. 6-9, there is no banknote skew feeding prevention roller 32, and there exists a banknote skew feeding reduction effect only with a protruding guide. . However, if the pressing force is increased by the spring 31 to increase the banknote skew resistance force C, the conveyance resistance force at the time of separation also increases, which is not desirable.

  Therefore, the spring 31 is set so that it does not retract even when a banknote collides with the protruding portion 30a during stacking of the banknote, and does not become a separation resistance force during separation. Thereby, even if the protruding portion 30a can be rotated, the folding force is sufficiently suppressed during stacking, retracted during separation, does not become separation resistance, and the pressing force necessary to hold the skew of the bill is suppressed. This can be applied to the skew prevention roller 32.

  Further, a structure in which the stack guide length expands and contracts in order to prevent banknotes and the like jammed during the transaction from entering the back side of the stack guide 14 will be described. If banknotes enter the back side of the stack guide 14, it is difficult to confirm the number of sheets when a failure occurs. Therefore, the stack guide slide portion 20 is provided, and the spring 22 applies a force that protrudes toward the back plate 16 side. At this time, the guide roller 21 contacts the back plate 16 to limit the position of the stack guide slide portion. As a result, the stack guide 14 can be rotated while the necessary nesting amount is secured. Furthermore, by sliding the stack guide slide portion, the tip protrusion amount of the stack guide 14 from the back wall 16 can be minimized, and the apparatus can be miniaturized.
