BACKGROUND OF THE INVENTION
The present invention relates to a banknote stacking apparatus that stacks banknotes in a banknote depositing / dispensing apparatus or the like incorporated in an ATM (automated teller machine).
[0002]
[Prior art]
A banknote deposit / withdrawal device that automatically performs banknote deposit / withdrawal processing is incorporated in ATMs and money changers installed in banks and the like. In general, this type of banknote depositing / withdrawing apparatus includes a depositing / withdrawing unit for depositing / withdrawing banknotes, an identification unit for identifying the type and authenticity of banknotes, and an intermediate pool for temporarily holding deposited banknotes and paying out banknotes Banknote stacking unit that sequentially stacks banknotes that are sequentially loaded in the deposit / withdrawal unit and the intermediate pool unit. Processing is required.
[0003]
[Problems to be solved by the invention]
However, in the conventional banknote stacking process, since banknotes are pressed one by one with a sheet metal fork-shaped banknote pressing member that moves linearly in the vertical direction, high-speed processing is difficult, and banknotes stacked first The banknote stacking posture is disturbed due to the influence of the state.
[0004]
The object of the present invention is not to allow the accumulation processing to be speeded up by accumulating the banknotes while knocking in the incoming banknotes, but to lessen the influence of the previously accumulated banknotes and to orderly stack the banknotes. It is in providing the banknote stacking device which can do.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a banknote stacking apparatus according to the present invention is a banknote stacking apparatus for sequentially stacking banknotes sequentially loaded into a banknote stacking section, and stacking stages for stacking banknotes loaded into the banknote stacking section. And a banknote carrying means for carrying banknotes one by one above the stacking stage in the banknote stacking unit, and a banknote carried by the banknote carrying means above the stacking stage from above the stacking stage. The banknote stacking mechanism is located on both sides in the horizontal direction of the banknotes carried above the stacking stage, and the stacks the banknotes by rotating downward from above. A pair of butterflies knocked down on a stage, a butterfly drive system for rotating the butterfly, and the butterfly drive system, the banknotes in the banknote stacking unit And a drive control means for operating in a carried-the timingThe butterfly drive system includes a drive source including a solenoid;
  A pair of drive shafts that rotatably support the butterflies, and a power transmission mechanism that transmits the power of the drive source to the drive shafts to rotate the butterflies. Both ends are wire-shaped fixed to the drive shafts.
[0006]
If you do thisThe banknote stacking process can be further speeded up by knocking down the banknotes by rotating the butterfly, and the structure of the banknote stacking mechanism is simplified compared to the conventional one in which the banknote pressing member moves linearly. Not only forgiveness, but also space efficiency.
[0007]
Also,in this wayBy converting the linear motion 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 stacking process can be further accelerated.
[0008]
AlsoBothWire-like end fixed to each drive shaftBy using the butterflyIn addition, since the strength can be increased as compared with the sheet metal fork-shaped banknote pressing member, not only the butterfly can be moved at a higher speed but also damage to the stacked banknotes can be prevented.
[0009]
The banknote carrying means includes a transport roller in the vicinity of the carry-in entrance of the banknote stacking unit, and the drive control unit positions the butterfly below the banknote when the banknotes are carried into the banknote stacking unit. And at the stage where the banknote is held by the transport roller, the butterfly is moved to the upper side of the banknote.RotationAfter that, it is preferable that the butterfly is rotated from the upper side to the lower side to knock the banknotes onto the stacking stage when the banknotes are completely loaded. In this case, by loading the banknotes onto the butterfly, it is possible to prevent interference with the previously stacked banknotes and avoid the disturbance of the stacking posture and the occurrence of jamming, and the loaded banknotes are held by the transport rollers. At this stage, since the butterfly is moved to the upper side of the banknote, it is possible to avoid the inconvenience that the butterfly disturbs the posture of the incoming banknote during the upward movement.
[0010]
Moreover, it is preferable that the said drive control means rotates the said butterfly upwards, when substantially 3/4 of a banknote is carried in in the said banknote stacking part. In this case, since the butterfly is rotated upward when most of the banknotes are carried into the banknote stacking unit, interference with the previously stacked banknotes can be reliably prevented, and the butterfly can be rotated downward. It is possible to shorten the waiting time until it is made as fast as possible and to speed up the processing.
[0011]
Further, the apparatus further comprises stage elevating means for elevating the accumulation stage, and elevating control means for elevating and lowering the accumulation stage so that the butterfly maintains a predetermined rotation posture when the butterfly is in the lower position. Is preferred. In this case, since the bill carry-in space can be kept constant, not only is it possible to perform a stable stacking process regardless of the amount of stacked banknotes, but also interference with previously stacked banknotes is ensured. And banknotes can be collected in an orderly manner.
[0012]
In addition, it is preferable that a sensor for detecting the rotational position of the butterfly is further provided, and the elevation control unit controls the elevation of the integrated stage based on a detection signal of the sensor. In this case, the butterfly functions as a member for detecting the amount of stacked banknotes, and as a result, the number of parts is reduced and the structure is simplified as compared with the case where a dedicated detection member is provided. be able to.

As shown in these drawings, in the banknote acceptance standby state in the accumulation mode, the butterfly 308a is at the lower position, and the banknote P fed from the transport port 301 is carried onto the butterfly 308a. The butterfly 308a pivots upward when approximately 3/4 of the bill P is carried into the intermediate pool section 300, that is, when the rear end side of the bill P is sandwiched between the belt conveyance body 303 and the pickup roller 304. Is done. At this time, the butterfly 308a moves upward of the bill P while flipping up both ends of the bill P in the width direction. After that, when the banknote P is completely loaded, the butterfly 308a is rotated from the upper side to the lower side, and the banknote P is knocked down on the lift blade 411 (on the stage 407). By repeating this series of operations, a plurality of banknotes P are neatly stacked on the lift blade 411. Further, in the stacking mode, each time a banknote P is stacked, the detection signal of the butterfly position sensor 308d is checked. If the butterfly position sensor 308d is in the non-transmissive state, the lift blade 411 is moved to a predetermined stroke. Lower. In other words, the lift blade 411 is sequentially lowered so that the butterfly 308a rotated downward maintains a predetermined rotation posture (lowermost position), thereby securing a bill carrying space of a certain height below the belt conveyance body 303.

A stopper surface 7c is formed. That is, in the storage mode, as shown in FIG. 16, after the cam 7 (lift motor 6) is rotated in the first direction, the rotation is stopped based on the cam arm position detection of the uppermost position sensor S1. As a result, the lift blade 411 reaches the uppermost position C described above and releases the separation between 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 cam arm position detection (cam position detection) of the lowermost position sensor S2 (S3), the deposited banknote P is stored in the safe 400. It 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 of the return position sensor S4. As a result, the lift blade 411 reaches the return position B described above, and the deposited banknote P can be fed out. At this time, 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 movement of the cam pin 8 to the upward side 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 that the deposited banknote P is erroneously stored in the safe 400 can be prevented.

As shown in this figure, in the return count feed control, the lateral transport motor 607 and the vertical transport motor 606 are driven upward (S2102, S2103) in response to the feed start command (S2101), and the lift motor 6 of the denomination to be fed out. Is driven in the second direction, and while the cam 7 (lift blade 411) is moved to the return position (S2104), the feeding sensor 306 determines whether the banknote P is fed out (S2105). In this state, the lift motor 6 is driven upward (S2106) for a predetermined time (20 ms) while judging whether the detection signal of the feeding sensor 306 has changed within a predetermined time (20 ms), but the lift blade 411 is returned. If the feeding does not start even when the position is reached (S2107), the lifting motor 6 is moved to the lowest position (S2108), and then the feeding process is repeated up to twice (S2109). On the other hand, when the bill P starts to run out, the separation solenoid 311 is turned on (S2112) when the intermediate passage sensor 312 detects the leading edge of the fed bill P (S2110) and transports 15 steps (S2111). When the intermediate passage sensor 312 detects the trailing edge of the fed banknote P (S2113), the counting process is performed (S2114). Thereafter, it is determined whether or not the return count end recognition control is in the end recognition state (S2115). If the determination is YES (Yes), the return count processing end routine is executed (S2116) to end the return count feed-out control. To do. On the other hand, if the above determination is NO (No), the separation solenoid 311 is turned off (S2118) after 70-step conveyance (S2117), and the process returns to step S2105 to continue the return feeding process.
