Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paper sheet stacking apparatus and a paper sheet handling apparatus.
[0002]
[Prior art]
As described in Japanese Patent Application Laid-Open No. 2000-128414, a configuration in which a guide for guiding banknotes and an impeller are arranged to overlap is known. The banknotes are plunged into the overlap part to give friction resistance to the banknotes sandwiched between the guide and the impeller, temporarily stop the banknotes, and then stack by pushing out the banknotes with the rotating impeller It was.
[0003]
[Problems to be solved by the invention]
The above prior art does not consider the case where paper sheets having various stiffnesses, masses, and friction coefficients are handled by the same mechanism. When handling such paper sheets, it is necessary to consider collision buckling when entering the overlap portion and preventing paper sheets from slipping through the overlap portion. In order to prevent slipping, it is necessary to temporarily stop the paper sheet at the overlap portion, that is, to consume the kinetic energy of the paper sheet with frictional resistance.
[0004]
However, the frictional resistance and rigidity of the paper sheet surface vary depending on the type and state of the paper sheet. Therefore, in order to prevent slipping-through, a state with the lowest friction coefficient is assumed, and the amount of overlap between the impeller and the guide and the rigidity of the blade are determined. The overlap amount is large for paper sheets with a low friction coefficient and paper sheets with a large mass, and conversely, it is small for paper sheets with a large friction coefficient and paper sheets with a small mass.
[0005]
However, when the overlap amount is increased, there is a problem that the collision angle between the paper sheet and the blade increases, and the paper sheet is likely to buckle. Paper sheets with low rigidity, such as wrinkles and folds, are more likely to buckle.
[0006]
Moreover, many paper sheets with wrinkles and folds have been in circulation for a long time, and the coefficient of friction is much lower than at the time of issuance. Therefore, when there is a paper sheet having a low coefficient of friction and easy to be buckled by impact, the conventional technology may not be able to stack normally due to slipping through or buckling. In other words, there is a risk that the paper sheets will be buckled by collision and bend and stay in a bellows shape, or may not pass through and accumulate normally.
[0007]
Therefore, an object of the present invention is to provide a paper sheet stacking apparatus and a paper sheet handling apparatus that have few obstacles and high reliability.
[0008]
[Means for Solving the Problems]
The above purpose is a paper sheet stacking apparatus that stacks a plurality of transported paper sheets, a pair of rollers that sandwich the paper sheets and send them to the stack space, and a paper sheet passage that detects the passage of the sent paper sheets A sensor, a blade roller having a blade portion for holding the paper sheet sent to the stack space together with a stack guide, and a control unit connected to the paper sheet passage sensor and controlling the rotation of the blade roller. The control unit rotates the blade roller based on a paper sheet passage signal, and controls the paper sheet detected to pass by the paper sheet passage sensor to be sandwiched between the blade portion and the stack guide. Ru be achieved by.

[0013]
In FIG. 3, the banknote depositing / withdrawing mechanism 40 of a present Example is shown. The banknote depositing / withdrawing mechanism 40 has a shutter 10 that opens when a banknote is inserted or removed, and a pickup roller 19, a separation roller 20, a gate roller 21, and a separation roller that form a separation port for separating banknotes one by one when depositing.

[0014]
The stack space is a space in which banknotes are accumulated. In this embodiment, the stack space indicates a space surrounded by the pressing plate 11, the stack guide 12, the guide 17 which is the bottom surface, and the partition plate 16 in FIG. Yes. That is, the banknotes sent by the roller pair are accumulated in the stack space of the banknote deposit / withdrawal mechanism 40.
[0015]
In the vicinity of the banknote stacking port, a clamping means for clamping and stopping a banknote sent to the stack space at the time of stacking of the dispensing operation, and a transport guide 14 for guiding the transported banknote are provided. The pinching means of the present embodiment includes a blade roller 15 having a stack blade portion composed of an elastic member and a stack guide 12 that guides a bill sent to a stack space in the bill depositing / dispensing mechanism 40 at the time of stacking in a dispensing operation. And is configured.
[0016]
The bill passage sensor Se of this embodiment is optically provided so as to sandwich the conveyance path in the vicinity of the bill stacking port, and is divided into a light emitting side and a light receiving side, respectively, and judges whether or not a bill is passed by light shielding. In this embodiment, the blade portion of the blade roller 15 has a hollow structure.
[0017]
As shown in FIG. 4, a shielding plate 34 is provided coaxially with the shaft on which the blade roller 15 and the stack roller 33 are attached, and an optical rotation amount detection sensor 35 is provided at a position past the shielding plate 34. There is a portion through which light passes at a predetermined position of the shielding plate 34, and the rotational position of the blade roller 15 can be detected by a signal (dark to bright, or bright to dark) from the rotation amount detection sensor 35. The rotation of the blade roller 15 can be controlled based on the information.
[0018]
FIG. 5 is a diagram showing the axial relationship between the clamping means at the banknote stacking port, that is, the blade roller 15, the banknote, and the stack guide 12. The blade roller 15 is provided at three intervals in the axial direction, and there are two sets of the stack roller 33 and the conveying roller 13 between the blade rollers 15. The blade roller 15 and the stack guide 12 are arranged so as to be shifted in the axial direction, and the blade roller 15 rotates so that the blade portion overlaps between the stack guides 12 provided in the axial direction. It is configured.
[0019]
Next, the bill dispensing operation will be described with reference to FIGS. When the dispensing operation is started, the push plate 11 is moved to the dispensing position by a drive motor (not shown). In order to stack the withdrawal banknote 30 in the banknote depositing / withdrawing mechanism 40, the banknote 30 is conveyed from each denomination box 48 or the like. At this time, the blade roller 15 is stopped at a predetermined position where the blade portion does not overlap the stack guide 12 as shown in FIG. The conveyed banknote 30 passes through the banknote passage sansa Se, is transported in a transport path formed by the transport roller 13 and the guide 14, and passes between the stack guide 12 and the blade roller 15 in the A direction, that is, the stack. It is emitted in a direction corresponding to the extension of the conveyance path in the space.
[0020]
The banknotes 30 that are not pinched by the transport roller 13 and the stack roller 33 are rotated by a predetermined amount in the direction B in the blade roller 15 and stopped by being sandwiched between the stack guides 12 as shown in FIG. The timing at which the blade roller 15 rotates in the direction B is after the passage sensor Se detects the trailing edge of the bill and a predetermined time has elapsed. This predetermined time is determined by, for example, the bill conveyance speed, the rotation speed of the blade roller 15, the position at which the passage of the bill is detected by the bill passage sensor Se, and the like, as described above, by the conveyance roller 13 and the stack roller 33. The rotation of the blade roller 15 is controlled so as to sandwich the banknote 30 that is not pinched. That is, the banknote 30 is pinched by the pinching means after the pinching by the roller pair arranged closest to the stack space is released.
[0021]
Further, the rotation amount of the blade roller 15 may be a predetermined rotation amount, or may be stopped when it is detected that the bill 30 is stopped. In the former case, the type and state of the banknote can be read by the discrimination unit 42 and the rotation amount determined based on the information can be obtained. Here, the state of the banknote is, for example, rigidity, and the rotation amount of the blade roller 15 is changed between a banknote whose rigidity is reduced by circulation such as a banknote with many wrinkles and a banknote with high rigidity such as a new ticket. it can. At this time, a database indicating the correspondence between the type / state of the banknote and the rotation amount of the blade roller 15 is prepared in advance, and the control unit 100 described later performs control according to the state of each banknote. In the latter case, it is necessary to provide a bill stop confirmation sensor for detecting the stop of the bill. For example, an optical movement amount measuring device can be applied to the sensor. If this sensor is provided and the rotation amount of the blade roller 15 is controlled, an appropriate frictional resistance force can be individually applied according to the banknote rigidity and banknote mass, and the banknote is not damaged.
[0022]
As shown in FIG. 6, when the blade portion of the blade roller 15 and the stack guide 12 are waiting in a state where they do not overlap, the conveyed bills 30 are not sandwiched between the conveyance roller 13 and the stack roller 33, Since the stack guide 12 and the blade roller 15 are sandwiched after the unconstrained state, the banknote 30 can be reliably stopped without buckling.
[0023]
The banknote 30 can be more reliably stopped by the surface of the blade | wing part of the blade roller 15 having high friction, and the blade roller 15 being comprised with an elastic member. Since the blade roller 15 of the present embodiment is made of a high-friction elastic member, for example, a rubber material, a sufficient frictional resistance can be given to the banknote 30. Further, the surface of a polymer material such as polyimide may be coated with a high friction material.
[0024]
The frictional resistance is applied in a direction substantially opposite to the movement direction (A) of the banknote 30, and the nipping between the transport roller 13 and the stack roller 33 is released, and the frictional resistance acts on the banknote 30 in an unconstrained state. Can be prevented. FIG. 7 shows a state in which a bill is held between the blade roller 15 and the stack guide 12. Since the blade roller 15 is in a position where the blade portion overlaps the stack guide 12, the banknote stops in a wave shape.
[0025]
The banknotes that are nipped and stopped between the blade roller 15 and the guide are then rotated 180 degrees or more in the rotation direction C, that is, in the direction to release the pinching, as shown in FIG. The blades push out the banknotes 30 and stack the banknotes 30 in a standing position along the partition plate 16. Since it is a stack mechanism that aligns the trailing edges of banknotes, it can be stacked regardless of the size of the banknotes 30. The blade roller 15 stops at the initial position after stacking, and waits to stack the bills that are subsequently conveyed.
[0026]
After the above operation is repeated and a predetermined number of denominations have been accumulated, the push plate 11 is pushed out, a withdrawal bill is sandwiched between the partition plate 16, and a predetermined operation is performed to complete the withdrawal operation. .
[0027]
FIG. 9 is a flowchart showing the above-described withdrawal operation, and FIG. 10 is a block diagram of control related to the withdrawal operation. A control flow in the dispensing operation will be described with reference to FIGS. 9 and 10.
[0028]
A control unit 100 shown in FIG. 10 controls the operation of the entire bill handling apparatus, and controls the first drive circuit 102, the second drive circuit 104, and the third drive circuit 108 in the dispensing operation. Hereinafter, the control flow of the dispensing operation will be described with reference to FIG.
[0029]
When the bill handling apparatus enters the dispensing operation, the position sensor 107 detects the position of the pressing plate 11 (S001). If the second determination unit 106 determines that the position of the push plate 11 is not at the withdrawal position, the control unit 100 instructs the second drive circuit 104 to drive the push plate 11 to the withdrawal position, and the second The motor 105 is controlled to drive the push plate 11 to the dispensing position.
[0030]
Next, the rotation amount detection sensor 35 detects the position of the blade roller 15 (S002), and if the first determination unit 101 determines that the blade roller 15 is not in a predetermined rotation position for dispensing, the control unit 100 instructs the first driving circuit 102 to drive the blade roller 15 to a predetermined rotational position, and controls the first motor 103 to drive the blade roller 15 to the predetermined rotational position.
[0031]
Next, a banknote is conveyed to the banknote depositing / withdrawing mechanism 40, and passage of a banknote is detected by the banknote passage sensor Se (S003). The first determination unit 101 determines that the bill has passed, and the control unit 100 controls to drive the blade roller 15. At this time, depending on the attachment position of the bill passage sensor Se, the conveyance speed of the bill, etc., it takes time until the bill that has passed the bill passage sensor Se arrives at the bill collection port of the bill deposit / withdrawal mechanism 40. It waits until the roller 15 is driven (S004). If the banknote passage sensor Se is provided at a position for detecting a banknote in the banknote stacking port, there is no need to wait.
[0032]
After waiting for a predetermined time, the control unit 100 controls to drive the blade roller 15, and the blade roller 15 rotates in the direction B shown in FIG. 7 (S005), and the bill is sandwiched between the blade portion and the stack guide 12. .
[0033]
The blade roller 15 rotates by a predetermined amount (S006), and when the banknote is stopped and pinched, the control unit 100 stops driving the blade roller 15 (S007). The amount of rotation of the blade roller 15 may be a predetermined amount of rotation, or may be changed depending on the type or rigidity of the bill. When changing the amount of rotation depending on the type or rigidity of the banknote, the type or rigidity of the banknote conveyed by the discrimination unit 42 is determined, and the control unit 100 performs control according to the type based on the determination information.
[0034]
Thereafter, the blade roller 15 is driven in the direction C shown in FIG. 8 (S008), and when it rotates by a predetermined amount (S009), the blade roller 15 is stopped (S010).
[0035]
When it is confirmed that all banknotes to be dispensed are stacked (S011), the control unit 100 drives the push plate 11 through the second drive circuit (S012), and confirms that the push plate 11 has been moved by a predetermined amount. When detected by the position sensor 107 (S013), the driving is stopped (S014), and the dispensing operation is finished.
[0036]
At the time of dispensing, the stack roller 33 and the transport roller 13 basically rotate at a constant speed in response to a drive signal from the third drive circuit 108. The rotation direction and the rotation amount of the blade roller 15 are controlled by a signal from the banknote passage sensor Se and a signal from the rotation amount detection sensor 35 that the shielding plate 34 attached to the shaft of the blade roller 15 passes.
[0037]
In this embodiment, the blade roller 15 has two blades. However, by using three blades, it is possible to reduce the amount of rotation of the blades for processing one banknote and increase the processing speed. However, the angle between the blades becomes 120 degrees, and there is a possibility that the conveyance path is blocked. In order to prevent this, the number of blades is not limited because the blades may be deformed by being applied to the guide 14.
[0038]
Further, in this embodiment, as shown in FIG. 5, a plurality (three) of the blade rollers 15 are provided in the axial direction (banknote width direction), so that at least one banknote is conveyed evenly while being skewed or shifted. It can be held between the two blade rollers 15 and the guide.
[0039]
Further, by performing bill passage detection at the rear end of the bill, even a bill having a different size can be accumulated with the same control regardless of the denomination because the rear end of the bill surely passes through the holding of the pair of rollers and is given frictional resistance.
[0040]
In addition, by providing the blade roller 15 whose rotation is controlled so that the banknote is held after the conveyance roller 13 and the stack roller 33 of the banknote passing through a predetermined position are released, the blade roller 15 is moved to the initial position. Regardless, it becomes possible to stack banknotes.
[0041]
Further, since the blade portion of the blade roller 15 comes into contact with the bill after the bill is in an unconstrained state, the blade portion surface is less likely to be worn compared to the prior art and can be used for a long time.
[0042]
In the above embodiment, in order to completely prevent the banknote from buckling, a frictional resistance force is gradually applied to the banknote by the blade roller 15 after the rear end of the banknote is removed from the holding between the transport roller 13 and the stack roller 33.
[0043]
On the other hand, as another embodiment, the standby position of the blade roller 15 is set to a position overlapping with the stack guide 12, and a frictional resistance is applied from the leading edge of the banknote being conveyed, but the force is less than the conventional one. It is set as above, and after the banknote passes a predetermined amount (timing is measured by the banknote passage sensor Se), the blade roller 15 is rotated by a predetermined angle in the direction B shown in FIG. 6 to stop the banknote. it can.
[0044]
As described above, since it is possible to stack banknotes regardless of the initial position of the blade roller 15, the position where the blade roller 15 overlaps the stack guide 12 may be set as the initial position.
[0045]
In this case, the amount of overlap can be made smaller than in the past. Therefore, what is necessary is just to set it as the overlap amount of the grade which prevents buckling of the banknote with the lowest rigidity in the range which can be assumed. Even when stacking highly rigid banknotes, slipping can be prevented by controlling the blade roller 15 to rotate and pinch.
[0046]
However, in this case, since a bill enters the overlap portion, a viscoelastic material such as a polyimide sheet is preferable on the outermost surface of the blade roller 15 without using a high friction member.
[0047]
Even with the banknote accumulation as described above, since the amount of rotation for holding the banknote of the blade roller 15 is small while preventing buckling of the banknote, it is possible to cope with further high-speed processing.
[0048]
In the present embodiment, an example in which the paper sheet stacking apparatus is applied to the banknote depositing / dispensing mechanism 40 has been shown, but the present invention can also be applied to the banknote stacking port of the banknote cassette 47 and the denomination box 48.
[0049]
According to the above configuration, there are few obstacles that the banknote collides and buckles, the banknote folds and stays, or slips and cannot be normally accumulated, and wear caused by friction between the blade part and the banknote is also conventional. Since it can be reduced compared with the above, it is possible to provide a highly reliable banknote stacking apparatus and paper sheet handling apparatus that can be used over a long period of time.
[0050]
【The invention's effect】
According to the present invention, it is possible to provide a paper sheet stacking apparatus and a paper sheet handling apparatus with less obstacles and high reliability.
