2. Description of the Related Art Generally, a banknote handling machine of this type is shown in FIG.
As shown in, the banknotes deposited in the deposit port 111 are subjected to discrimination processing by the deposit discriminating section 112, the discriminated banknotes are temporarily held in the temporary holding section 113 for return / acquisition, and when the deposit is confirmed, the temporarily held banknotes are Store in the deposit store section 114,
From the deposit store section 114, the stackers 115 to 1 by denomination
I am replenishing to 17 for withdrawal. At the time of withdrawal, banknotes are fed out from the predetermined money type stackers 115 to 117, and the fed out banknotes are discriminated by the withdrawal discrimination section 118, and then the withdrawal port 11
It is released to 9. At this time, the defective banknotes and the banknotes that have been canceled have been returned to the return port 120, and the banknotes that have been canceled have been collected in the reject cartridge 121.

As described above, the banknote processing machine that effectively circulates the deposited banknotes as the dispensed banknotes is in the mainstream. In this case, the deposited banknotes have a large degree of dirt and damage, When the bill is discriminated as unsuitable for the circulation bill due to its outer shape, it is collected in the reject cartridge at the time of bill discrimination.

However, even if it is possible to determine the outer shape of a bill such as the stain or the degree of damage of the bill, a weak bill that has been used for many years in circulation is not suitable for a circulation bill because it has a low extension return force and is easily deformed. Despite this, since it could not be distinguished, it was handled as a withdrawn banknote, and this weak banknote tended to cause a paper jam at the time of withdrawal.

Further, an impeller with improved bill taking-in performance is attached to an entrance portion for accumulating bills such as a stacker of denominations. In this case also, even if the impeller blades are damaged or fallen, it is not clear. However, since the paper was transported regardless of whether the transport system members were damaged or not, it is easy to induce paper jam when it is damaged, and especially paper jam during stacking cannot be detected. Had a problem of increasing.

[0006]

SUMMARY OF THE INVENTION Therefore, the present invention pays attention to the sound of a banknote being conveyed, and by grasping the sound quality and volume of the sound produced during the banknote transfer, it is possible to accurately know the status of the banknote transfer. The purpose of the present invention is to provide a banknote handling machine capable of carrying out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. The drawing shows a banknote processing machine for depositing and withdrawing banknotes. As shown in FIG.
A deposit / withdrawal transfer processing group 13 for transferring banknotes 12 is provided on the upper side of 1, and a storage group 14 for allowing the banknotes 12 to be stored and delivered is provided on the lower side, and the upper and lower sides of the apparatus main body 11 are a transport system and a storage system. It is composed of and.

The above-mentioned deposit / withdrawal transfer processing group 13 includes a return port 15 and a deposit port 16 from the upper side on the front upper surface of the apparatus main body 11.
And a withdrawal port 17, and the banknotes 12 inserted into the withdrawal port 16 are stored in the lower storage group 14 via the deposit path 18.
The banknotes 12 that have been deposited into the payout port 17 and have the banknotes 12 fed from the storage group 14 into the payout port 17 are dispensed to the payout port 17 via the payout path 19.

The banknotes inserted into the above-mentioned deposit port 16 are guided to the deposit discriminating section 20 arranged at the upper middle position to discriminate them.
Subsequently, it is conveyed and connected to the temporary holding section 21 arranged at the lower back position so as to convey it, and at this time, when the payment discriminating section 20 discriminates that the back side is in the state of being taken, it is guided to the front / back reversing section 22.
Here, after the front and back are reversed and the front and back are aligned, the paper is conveyed to the temporary holding section 21. In addition, the banknotes that are not properly discriminated by the deposit discriminating unit 20 are returned to the return route 2 provided above the deposit discriminating unit 20.
It returns to the return port 15 through 3.

The above-mentioned temporary holding unit 21 is the deposit store unit 2
The banknotes 12 are divided into upper positions of 4 and temporarily held for each deposit transaction, and temporarily held for each transaction completion when the deposit transaction is confirmed, are stored in the deposit store section 24 for the next deposit processing, and We are trying to obtain a sufficient deposit capacity for deposit bills.

From the deposit store section 24, the optimum replenishment timing is selected to replenish the first to third stackers S1 to S3 of the respective denominations, and if it is determined that the discrimination is defective at this time, it is collected in the reject cartridge C. is doing. In this replenishment operation, first, the bills fed out from the deposit store unit 24 are guided to the deposit discriminating unit 20 and are then stored in the stackers S1 to S3 or the reject cartridge C via the dispense discriminating unit 25.

Thus, from the deposit port 16 → 20 (→ 2
2) → 21 → temporary deposit route to deposit store section 24,
The depositing path 18 is configured with a transport system via a series of signs from the depositing store section 24 to the storage paths from the → 20 → 25 → the first to third stackers S1 to S3 (→ C).

On the other hand, the withdrawal route 19 has the first to third positions.
The banknotes fed from the stackers S1 to S3 are used as the dispensing discriminating section 25.
And discharges to the withdrawal opening 17 after the identification confirmation is performed, and the delivery system from the first to third stackers S1 to S3 to the withdrawal opening 17 via the withdrawal identification section 25 is introduced. The withdrawal path 19 is configured.

The above-mentioned storage group 14 is composed of a deposit store section 24 having the above-mentioned temporary holding section 21, first to third stackers S1 to S3, and a reject cartridge C. The third stackers S1 to S3 have a function of collecting and feeding out banknotes and store three denominations of 10,000 yen, 1,000 yen, and 5,000 yen by denomination, and the reject cartridge C is used for withdrawal transactions and replenishment. Collects defective banknotes, banknotes that are not suitable for distribution, banknotes that have been forgotten, etc. that occurred during processing. In this case, the first stacker S1 for storing 10,000-yen bills has a large frequency of insertion and removal, so it is provided with a slightly larger size. The second stacker S2 for storing 1,000-yen bills and the third stacker S3 for storing 5,000-yen bills. They are provided in approximately the same size.

By the way, as shown in FIG. 2, a corrugated conveyor path 26 for curving the banknotes 12 into a corrugated shape and conveying it is provided in the conveying path in the latter stage of the dispensing discriminating section 25. A first microphone 27 that collects the conveyance sound of the banknote 12 that is corrugated and conveyed in the vicinity is provided, and the strength of the waist of the banknote 12 is determined by the sound output that is collected by the first microphone 27.

In this case, the bill 12 is passed through the corrugated transport path 26 and is transported while curving in a wavy shape.
When the bill 12 is greatly curved and when it is extended and restored, a sound indicating the strength of the waist is emitted. For example, in the case of a new banknote that is relatively strong and suitable for circulating banknotes, a high-frequency sound called “crisp”, which is peculiar to banknotes, is generated when passing through the corrugated transport path 26. In the case of an unsuitable old banknote that has a weakness, the corrugated transport path 26
Emits a small sound when passing. In this way, the strength of the waist of the banknote 12 can be accurately determined from the sound quality and the volume.

Therefore, when a weak banknote 12 is deposited, it is collected in the reject cartridge C as an unsuitable banknote 12, so that the banknotes in the stackers S1 to S3 are always used as good banknotes suitable for circulation. Put it in storage standby. Therefore, since the banknotes unsuitable for the stackers S1 to S3 can be eliminated in advance, all the banknotes for dispensing will be good banknotes, and the paper jam at the time of dispensing can be surely reduced. You can

Further, a second microphone 29 for collecting the carrier sound of the blade 28a is arranged near the impeller 28 attached to the entrance of each stacker S1 to S3, and the second microphone 29 is arranged.
By the sound output collected by the microphone 29, it is possible to determine whether the bill is being conveyed or the performance state of the blade 28a of the impeller 28 is appropriate.

For example, as shown in FIG. 3, four blades 28
When the impeller 28 having a ... Is normally stacking the banknotes 12 and stacking the banknotes 12 ... In the stacker S1, as shown in FIG. 4, each of the four blades 28a ...
2 is periodically hit to generate a contact sound of the blades 28a.

At this time, as shown in FIG.
If one of 8a ... Is damaged or dropped, the contact sound period of the blades becomes irregular, and it is clear that an abnormality has occurred in the impeller 28. Therefore, in this case, the staff is immediately notified to perform the restoration process of the impeller 28,
It is possible to prevent the occurrence of paper jam.

Further, as shown in FIG. 6, when a paper jam occurs in the stacker S1, the blades 28a of the impeller 28 continuously generate a contact noise as shown in FIG.
It is possible to clearly determine the occurrence of a paper jam, and immediately stop the stacking operation at this time and stop the stacking operation at the initial stage of paper jam, so create a lot of paper jams or increase the paper jam phenomenon. Disappears. In the figure, 30 is a take-in roller, and 31 is a take-in detection sensor.

FIG. 8 shows a block diagram of a control circuit of the banknote processing machine. The CPU 81 controls each circuit device according to a program stored in the ROM 82, and the control data is readablely stored in the RAM 83.

The main motor M drives and controls each conveyance path based on the input information from the CPU 81, detects the conveyance processing state of the bills 12 conveyed based on this information by the conveyance bill detection sensor 84, and conveys the bills. The incoming bills 12 are distributed and controlled in a predetermined direction by the distribution plate f arranged at the conveyance branch position.

The first microphone 27 or the second microphone
The output of the sound collection frequency collected by the microphone 29 is amplified by the amplifier 85, the amplified value is shaped by the waveform shaping circuit 87 via the filter 86, and then the collected sound signal rising at the input port 88 is sent to the CPU 81. input.

The CPU 81 determines whether the detected value of the input sound collection signal is a proper sound or an abnormal sound, and when the CPU 81 determines through the first microphone 27 that an abnormal sound is generated, the distribution of the waist is weak. When it is determined that the banknotes are collected as inappropriate banknotes and the abnormal sound is generated through the second microphone 29, the CPU 81 issues an alarm 89 via the alarm 89 because the blade of the impeller 28 at the entrance of the stacker is abnormal or the paper jam occurs. Outputs an alarm sound for requesting work.

The timer T measures whether or not the output value of the contact sound generated by the blades 28a of the impeller 28 at the time of bill taking is generated in a constant cycle, and the timer value is used to determine the suitability of the blades of the impeller. To judge.

Therefore, in addition to the discrimination processing between the deposit discriminating unit 20 and the withdrawal discriminating unit 25, the microphones 27, 29 are also provided.
By using the sound detection process via ... In combination, it is possible to clearly distinguish between suitability and unfitness as a circulating bill.

The processing operation of the banknote handling machine thus constructed will be described with reference to the flow charts of FIGS. 9 and 10. FIG. 9 shows the transport processing operation of the corrugated transport path 26.
Now, the banknotes 12 are corrugated in the storing and conveying process of storing the banknotes 12 from the depositing store section 24 into the respective stackers S1 to S3 of each denomination or in the withdrawal process of withdrawing from the respective stackers S1 to S3 to the withdrawal opening 17. When the bill 12 passes through the path 26, the bill 12 is conveyed while curving greatly in a corrugated shape, and at this time, the bill emits various sounds depending on the quality of the paper, and the first microphone 27 collects the bill carrying sound emitted at this time. Then, the CPU 8 determines whether the collected value is a sound range suitable for the circulating bill or a sound range not suitable.
1 determines (step n1), and when the CPU 81 determines that the banknote is not suitable for circulation, it is guided to the reject cartridge C and collected. For this reason, when storing banknotes, banknotes that are not suitable for circulation can be removed and stored, so that only good banknotes are stored in the stackers S1 to S3, and therefore only good banknotes are dispensed at the time of dispensing and paper jams occur. Surely reduced (steps n2 to n3
).

FIG. 10 shows the operation of stacking banknotes on each of the stackers S1 to S3. In the stacking process in which the banknotes 12 are taken into the stackers S1 to S3 and conveyed, one banknote 12 is inserted into the impeller 28 one by one. Stacked in the stackers S1 to S3. The second microphone 29 collects the sound generated by the contact between the banknote 12 and the blades 28a ... At this time, and the CPU 81 determines whether or not the collected value is appropriate.
If it is determined to be abnormal, it is determined that the paper is jammed at the stacker entrance portion, and promptly the staff processing (steps n11 to n12).

On the other hand, when the abnormal sound is detected without detecting the taking-in of the bill 12, the timer T is set to check whether or not the impeller 28 is abnormal (steps n13 to n15).
At this time, if the receipt of bills is not detected, it is determined as a paper jam (steps n16 to n17), and even if a predetermined time has elapsed,
If the sound collection value collected by the second microphone 29 is irregular, the CPU 81 determines that an abnormality such as damage or dropout has occurred in the blades 28a of the impeller 28, and the CPU 81 outputs an alarm sound to the staff. Inform. As a result, the blade restoration process is performed immediately, the impeller restoration process can be performed early, and the occurrence of paper jam can be prevented (steps n18 to n).
twenty two).

As described above, it is possible to accurately determine a weak banknote that is unsuitable as a circulating banknote, and by using it in combination with the discriminating section, it is possible to determine not only the outer shape of the banknote but also the strength and weakness of the banknote, and the banknote as a circulating banknote. It is possible to clearly distinguish between good and bad. Therefore, it is possible to exclude and store unsuitable banknotes at the time of deposit, so that all of the standby banknotes used for dispensing will be dispensed as good banknotes, and paper jam at the time of dispensing can be reliably reduced. it can. Further, even when the blade of the impeller attached to the entrance of the bill storage unit is damaged or falls off, it can be clearly detected from the change in sound, and paper jam at the time of stacking can be prevented in advance.
