Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a banknote stacking apparatus for stacking banknotes in a banknote pay-in / pay-out device incorporated in an ATM (automatic teller machine).

[0002]

2. Description of the Related Art A banknote depositing / dispensing apparatus for automatically performing a bill depositing / dispensing process is incorporated in an ATM or a money changing machine installed in a bank or the like. Generally, this kind of banknote depositing / dispensing apparatus includes a depositing / dispensing unit for depositing / dispensing bills, an identification unit for identifying the type and authenticity of bills, and an intermediate pool for temporarily storing deposited bills and feeding out bills. Section, a safe for storing bills, and a transport section for transporting bills between the above-described sections, and in the above-mentioned depositing / dispensing section or intermediate pool section,
It is required to perform a banknote stacking process for sequentially stacking banknotes sequentially loaded.

[0003]

However, in the above-described conventional banknote stacking process, high-speed processing is difficult because banknotes are pressed one by one by a sheet metal fork-shaped banknote holding member that linearly moves in the vertical direction. In addition, there is a problem that the state of the banknotes stacked beforehand is affected by the state of the banknotes stacked earlier.

It is an object of the present invention to accumulate bills while knocking them down, so that the accumulating process can be speeded up. An object of the present invention is to provide a banknote stacking device that can be stacked.

[0005]

In order to achieve the above object, a bill accumulating apparatus of the present invention is a bill accumulating apparatus for successively accumulating bills sequentially carried into a bill accumulating section. A stacking stage for stacking bills to be carried in, a bill carrying unit for carrying bills one by one above the stacking stage in the bill stacking unit, and a bill carried above the stacking stage by the bill carrying unit. And a banknote stacking mechanism for hitting the banknotes from above onto the stacking stage.

[0006] Further, the bill stacking mechanism is located on both sides in the horizontal direction of the bill carried above the stacking stage,
A pair of butterflies for knocking the bill down onto the stacking stage by a turning operation from above to below, a butterfly drive system for turning the butterfly, and the butterfly drive system; It is preferable to include a drive control unit that operates at the timing of being carried into the vehicle. In this case, the banknote stacking operation can be further speeded up by hitting the banknote down by the rotating operation of the butterfly, and the banknote stacking mechanism of the banknote stacking mechanism is compared with the conventional one that linearly moves the banknote holding member. Not only can the structure be simplified, but also space efficiency can be increased.

The butterfly drive system includes a drive source comprising a solenoid, a pair of drive shafts rotatably supporting the respective butterfly, and transmitting the power of the drive source to the respective drive shafts. And a power transmission mechanism for rotating the rotary shaft. In this case,
By converting the linear movement of the solenoid having excellent responsiveness into the rotation of the butterfly, the butterfly can be moved at a high speed, and as a result, the bill accumulation processing can be further accelerated.

It is preferable that the butterfly has a wire shape with both ends fixed to the drive shafts. In this case, since the strength can be increased as compared with the sheet metal fork-shaped bill holding member, it is not permissible to make the butterfly move at a higher speed,
Damage to the stacked bills can also be prevented.

The bill carrying means includes a transport roller near a carry-in entrance of the bill accumulating section, and the drive control means, when the bill is carried into the bill accumulating section, is disposed below the bill. While positioning the butterfly, at the stage where the bill is held by the transport roller, move the butterfly to the upper side of the bill, and then, at the stage when the loading of the bill is completed, move the butterfly from above to below. It is preferable that the banknote be rotated and hit the bill on the stacking stage. In this case, by feeding the bills onto the butterfly, interference with the previously stacked bills can be prevented, and disturbance of the stacking posture and occurrence of jam can be avoided, and the carried bills are held by the transport rollers. At this stage, the butterfly is moved to the upper side of the bill, so that the inconvenience that the butterfly disturbs the attitude of the carried bill during the upward operation can be avoided.

[0010] It is preferable that the drive control means rotates the butterfly upward when approximately three-fourths of bills are carried into the bill stacking unit. In this case, the butterfly is rotated upward when most of the bills are carried into the bill stacking section, so that interference with the previously stacked bills can be reliably prevented, and the butterfly is rotated downward. It is possible to shorten the waiting time until the process is performed as much as possible, thereby increasing the processing speed.

[0011] Further, a stage elevating means for elevating and lowering the accumulating stage and an elevating control means for elevating and lowering the accumulating stage so that the butterfly keeps a predetermined rotation posture when the butterfly is at a lower position. It is preferable to further provide. In this case, since the carry-in space of the bills can be kept constant, it is not possible to perform a stable accumulation process regardless of the amount of the accumulated bills. And the banknotes can be stacked in an orderly manner.

It is preferable that the apparatus further comprises a sensor for detecting a rotation position of the butterfly, and the elevation control means controls the elevation of the accumulation stage based on a detection signal of the sensor. In this case, the butterfly
It functions as a member for detecting the amount of accumulated banknotes. As a result, the number of components can be reduced and the structure can be simplified as compared with a case where a dedicated detection member is provided.

On the other hand, when the deposited banknotes P are stored in the safe 400 in response to the depositing operation after the completion of the stacking process, the lift blade 411 moves beyond the return position B to the uppermost position C (separation release position) as shown in FIG. ). In the meantime, when the rising of the deposited bill P is restricted by contact with the belt transport body 303, the lift blade 411 retreats and pivots downward against the return spring 419, and traces the side face of the deposited bill P. The return spring 419 then returns to the parallel posture by the urging force of the return spring 419. Then, the lift blade 411, which has risen to the uppermost position C, reverses and descends to push down the deposited banknotes P and the stored banknotes P to be stored in the safe 400, as shown in FIG. In the feeding mode, the lift blade 411 moves up to the vicinity of the uppermost position C. At this time, stage 40

FIG. 11 is an internal plan view of the intermediate pool section showing the banknote stacking mechanism, and FIG. 12 is an internal left side view of the intermediate pool section showing the banknote stacking mechanism. As shown in these drawings, the banknote stacking mechanism 308 includes a pair of left and right butterfly 308a provided so as to overlap both ends in the width direction of the banknote P (stage 407) in plan view, and each butterfly 308.
Butterfly support shaft (drive shaft) that supports a vertically rotatable
308b, a butterfly drive link (power transmission mechanism) 308c for raising the pair of butterflies 308a in response to the driving of the butterfly solenoid 310, and a butterfly position sensor 308d for detecting the rotational position of the butterfly 308a. Have been. The butterfly 308a has a wire shape obtained by bending a metal wire, and both ends thereof are welded to a butterfly support shaft 308b. The butterfly drive link 308a converts a linear movement of the butterfly solenoid 310 into a rotational movement of the butterfly support shaft 308b, and rotates the butterfly 308a at high speed in accordance with the drive of the butterfly solenoid 310. The butterfly position sensor (photo interrupter) 308d is for detecting that the butterfly 308a is at the lowermost position.
When the light-shielding member 308e provided integrally with the shutter 08a is in the transmission position, the light-shielding member 308e is provided to detect the lowermost position of the butterfly 308a.

FIG. 13 is a left side view and a front view showing the operation of the butterfly in the stacking mode (a small amount of stacked banknotes).
FIG. 14 is a left side view and a front view showing the operation of the butterfly in the stacking mode (a large number of stacked banknotes). As shown in these figures, in the banknote receiving standby state in the stacking mode, the butterfly 308a is at the lower position, and the banknote P sent from the transport port 301 is carried into the butterfly 308a. The butterfly 308a rotates upward when approximately 3/4 of the banknote P is carried into the intermediate pool unit 300, that is, when the trailing end of the banknote P is held between the belt transport body 303 and the pickup roller 304. Is done. At this time, the butterfly 308a moves above the banknote P while jumping up at both ends in the width direction of the banknote P. Thereafter, when the transfer of the bill P is completed, the butterfly 308a is rotated downward from above, and the bill P is knocked down on the lift blade 411 (on the stage 407).
By repeating this series of operations, a plurality of bills P
Are orderly integrated on the lift blade 411. Further, in the stacking mode, each time one banknote P is stacked, the detection signal of the butterfly position sensor 308d is checked, and when the butterfly position sensor 308d is in the non-transmission state, the lift blade 411 is moved by a predetermined stroke. Lower it. In other words, by sequentially lowering the lift blades 411 so that the butterfly 308a rotated downward keeps a predetermined rotation posture (the lowest position), a bill carrying space of a certain height is secured below the belt transport body 303. Will be done.

FIG. 15 is an explanatory view of the lift drive mechanism and the lift blade in a standby state, FIG. 16 is an explanatory view of the lift drive mechanism and the lift blade in a storage mode,
FIG. 17 is an explanatory diagram of the lift drive mechanism and the lift blades in the return mode. As shown in these figures, the cam 7 of the lift drive mechanism 5 pushes up the cam pin 8 when rotated in the first direction, and pushes up the cam pin 8 when rotated in the second direction. And a second cam surface 7b. The first cam surface 7a is set at a distance from the center of rotation so that the lift blade 411 reaches the uppermost position (the cutting release position) from the lowermost position, while the second cam surface 7b sets the lift blade 411 at the lowest position. The distance from the rotation center is set so as to reach the return position from the lower position. First cam surface 7a and second cam surface 7b
The terminal portions of the second cam surface 7b overlap each other, and the terminal portion of the second cam surface 7b enters inside the terminal portion of the first cam surface 7b to form a groove-shaped stopper surface 7c. That is, in the storage mode, as shown in FIG.
After rotating the cam 7 (lift motor 6) in the first direction,
The rotation is stopped based on the detection of the cam arm position by the uppermost position sensor S1. Thereby, the lift blade 411
Reaches the above-described uppermost position C and releases the separation of the deposited banknote P and the stored banknote P. Thereafter, when the cam 7 is rotated in the second direction and the rotation is stopped based on the detection of the cam arm position (cam position detection) of the lowermost position sensor S2 (S3), the deposited bill P is stored in the safe 400. Will be. On the other hand, in the return mode, as shown in FIG. 17, after the cam 7 is rotated in the second direction, the rotation is stopped based on the detection of the cam arm position by the return position sensor S4. As a result, the lift blade 411 reaches the above-described return position B, and the deposited banknote P can be paid out. At this time, since the cam pin 8 has entered the concave groove formed by the stopper surface 7c, Even if the cam 7 continues to rotate due to a sensor failure or the like, the upward movement of the cam pin 8 is restricted by the stopper surface 7c. Therefore, the lift blade 411 does not reach the uppermost position due to a malfunction, and the inconvenience of the deposited bill P being erroneously stored in the safe 400 can be prevented.

Control section 700, the space for carrying in the banknotes P can be kept constant. As a result, it is not possible to perform a stable stacking process regardless of the amount of the stacked banknotes P. Interference with the stacked banknotes P can be reliably avoided, and the banknotes P can be stacked neatly.

Further, a butterfly position sensor 308d for detecting the rotational position of the butterfly 308a is further provided, and the control unit 700 controls the lift blade 411 to move up and down based on a detection signal of the butterfly position sensor 308d. The butterfly 308a
