Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automated teller machine for taking cash in and out by a user's operation and a control method thereof, and more particularly to an automated teller machine having a function of sterilizing banknotes and a control method thereof.

[0002]

2. Description of the Related Art An automatic teller machine having a function of sterilizing bills is disclosed in, for example, Japanese Patent Laid-Open No. 3-209595, and a sterilizing method by heating, ultraviolet rays and chemical application is shown. When the banknotes are sterilized by using the sterilization method by heating, a method of providing a means for heating the banknotes on the transport path and sterilizing the transported banknotes one by one is effective. The sterilization of bills by such heating is disclosed in JP-A-4-114652. Japanese Unexamined Patent Publication No. 4-114652 discloses a heating roller having a heating unit such as a heater built in a conveying path, and a heat sterilization unit including a heat-resistant belt attached so as to be wound around the heating roller. It is fed between the heating roller and the heat-resistant belt, and heat-sterilized by the sandwiching portion between the heating roller and the heat-resistant belt.

[0003]

As described above, when the heating roller and the heat-resistant belt wound around the heating roller are heated to a high temperature and the bills are heat-sterilized by passing the bills between them, the temperature of the bills is different from that of the heating roller. Before entering the space between the heat-resistant belts, the temperature is at about room temperature, and a large amount of heat is required to raise the banknotes at this temperature to a temperature at which they can be sterilized while being held between the heating roller and the heat-resistant belt. Furthermore, when the banknotes are continuously sterilized, a large amount of heat is taken from the heating roller and the heat resistant belt in a short time,
The temperature of the heating roller and the heat-resistant belt drops sharply. Moreover, not only heat is taken away from the bills, but also the heating roller and the heat-resistant belt itself radiate heat. For this reason, the heating roller and the heat-resistant belt are heated by the heating means during the sterilization, but a large-capacity heat source is required to supply a heat amount commensurate with the deprived heat amount in a short time. However, in practice, it is difficult to mount a large-capacity heat source due to problems such as power consumption and mounting space, and how to maintain the temperature of the heating roller and the heat-resistant belt at the sterilization temperature is an issue.

An object of the present invention is to provide an automatic teller machine and a control method thereof for surely sterilizing banknotes.

[0005]

SUMMARY OF THE INVENTION The present invention is directed to a deposit / withdrawal port for depositing / dispensing a bill, a storage unit for the bill, and a transport path for transporting the bill between the deposit / withdrawal port and the storage unit. It has a bill sterilization unit that heats and sterilizes the bills on the conveyance path, and the bill sterilization is interrupted in response to the temperature in the bill sterilization unit falling below a predetermined temperature.

Furthermore, the number of sheets to be continuously sterilized is limited to the number at which the heating temperature does not fall below a predetermined temperature.

Further, when the banknote sterilization is not performed, the heating temperature is set lower than a predetermined temperature, and a control method for raising the temperature to a predetermined temperature during the transaction for banknote sterilization is adopted.

[0008]

According to the present invention, since the bill sterilization is interrupted in response to the temperature in the bill sterilizing means becoming lower than the predetermined temperature, the bill sterilization can be surely performed.
In addition, by limiting the number of continuous sterilization to a number that does not cause the heating temperature to fall below a specified temperature, continuous sterilization of a certain number or less is possible, and the number of consecutive sterilization is the number of deposits or withdrawals of one transaction. By configuring so that it becomes possible to sterilize reliably without affecting the transaction.

Further, by controlling the temperature, an efficient structure can be obtained.

As described above, during the banknote sterilization, it is possible to continuously sterilize the banknotes while keeping the temperature of the banknote sterilization unit at the sterilization temperature.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an automatic teller machine which is an embodiment of the present invention.

In a deposit transaction, a user inserts a bill into the deposit / withdrawal port 1. The inserted banknotes are separated one by one by a separating mechanism (not shown) in the deposit / withdrawal port 1, and are conveyed to the discrimination section 3 by the conveying path 2. In the discrimination unit 3, the denomination,
Necessary discrimination such as authenticity, damage, number of sheets, etc. is performed, and further conveyed by the conveying path 4 and accumulated in the temporary accumulating mechanism 5. Here, when the transaction operated by the user is established, the banknotes are separated from the temporary stacking mechanism 5 by a separating mechanism (not shown), and the transport path 6 is separated.
Is conveyed again to the discrimination section 3 for discrimination, and the conveyance path 4,
Each denomination is conveyed to the denomination boxes 8 and 9 which are bill storage units through 7 and 2, and is accumulated and stored to complete the deposit transaction.

In the withdrawal transaction, the number of banknotes requested by the user is separated from each of the denomination boxes 8 and 9 by a separating mechanism (not shown) and delivered to the conveying path 2. A gate 10 is provided in the transport path 2 on the way, and the banknotes are transported to the sterilization unit 11 and sterilized by switching the gate 10 to the sterilization unit 11 side during withdrawal. The banknotes are sterilized and disinfected by the sterilization / disinfection unit 11, and then are again accumulated in the deposit / withdrawal port 1 through the transport paths 2, 4, and 7, and are discharged to complete the dispensing transaction. Since the sterilizing / disinfecting unit 11 performs heat sterilization as described below, the bills accumulated in the deposit / withdrawal port 1 may be warm. Therefore, the bill cooling unit 7a is provided on the transport path 7 to sterilize / disinfect. It is possible to prevent the banknotes that have been heat-sterilized by the unit 11 from being cooled to make the user feel uncomfortable. The transport path 2 also has a transport path portion that bypasses the sterilization unit 11, and can switch the gate 10 to bypass the sterilization unit 11.

When the amount of banknotes stored in the denomination boxes 8 and 9 becomes low, the banknotes are set in the removable banknote cassette 12 and the separator 13 is evacuated. The banknotes in the cassette 12 are fed out, sent to the discriminating unit 3 through the conveying path 6, the denomination is discriminated and counted in the discriminating unit 3, and then each money is passed for each denomination through the conveying paths 4, 7 and 2. Replenishment or loading to be stored in the seed boxes 8 and 9 is performed. Temporary stacking mechanism 5, banknote cassette 12,
The separator 13 can have the structure described in Japanese Patent Publication No. 4-31156, for example.

When one of the denomination boxes 8 and 9 is full, the banknotes are fed out from the denomination boxes 8 and 9 which are full, and the discriminating section 3 discriminates and counts the denominations, and then the cassette 1
The banknotes are stored in 2 and collected. Further, it is also possible to collect all the bills from the denomination boxes 8 and 9 and perform a close examination to count and confirm the amount of bills in the device. Further, it is possible to move the banknotes sequentially to the denomination boxes 8 and 9 and the banknote cassette 12 while passing through the discrimination section 3 and perform a close inspection to count and confirm the amount of banknotes in the apparatus. It is also possible to perform sterilization by switching the gate 10 of the transport path 2 when performing the above-mentioned collection and close inspection. Further, by moving the sterilizing / disinfecting unit 11 to the position shown in FIG. 6, it becomes possible to sterilize / disinfect banknotes at the time of deposit transaction, replenishment and loading operation.

Next, the sterilization / disinfection unit 11 in the automatic teller machine shown in FIG. 1 will be described with reference to FIG.

FIG. 2 shows the construction of the bill sterilization unit 11.

Reference numeral 14 denotes a metal heating roller for heat-disinfecting bills, which is supported by a rotary bearing (not shown), is connected to a heating roller driving motor 16 by a timing belt 15, and is heated by a heating roller driving motor 16
It is designed to be driven to rotate by. The heating roller driving motor 16 is a step motor, and its rotation direction and rotation speed are variable. The sensor 14a is a sensor that detects whether or not the heating roller 14 is rotating, and as will be described later, the heating roller 14 is rotated when the power is turned on, but if it does not rotate, a protective measure against heat is taken. Therefore, it is detected whether the heating roller 14 is rotating.

Reference numeral 17 denotes an electric heater for heating the heating roller 14 and has a heat generation amount enough to keep the surface temperature of the heating roller 14 at the sterilization temperature or higher. Further, a wiring 18 for supplying electric power to the electric heater 17 is provided with a switch 18 for controlling the supply of electric power, and the control unit 19 can turn on / off the electric heater 17. The thermal protector 18a functions as a fuse when the electric heater 17 cannot be turned off due to a failure of the switch 18 even if the temperature of the electric heater 17 rises above a predetermined temperature.

Reference numeral 20 is a temperature detector for measuring the surface temperature of the heating roller 14, and the measured temperature data is input to the control unit 19. The control unit 19 uses the temperature detector 2
Switch 18 based on the temperature data input from 0
To control the surface temperature of the heating roller 14.

Reference numeral 21 is a heat-resistant belt wound around the heating roller 14 and has a tension necessary for sterilizing bills, for example, 1
A tension of 6 kgf or more is applied. This heat resistant belt 2
A portion 22 where 1 and the heating roller 14 are in contact with each other is a heating portion of the bill, and the heat-resistant belt 21 is configured so that the bill is pressed against the heating roller 14 by a certain angle or more and conveyed, and the heating roller 14 and the heat-resistant belt 21 are By rotating, heating unit 2
The bill that has entered 2 is heat-sterilized while being conveyed.

Reference numerals 23 and 24 denote exhaust and intake fans for preventing the ambient temperature of the sterilizing / disinfecting section 11 from rising by heating the heating roller 14.

Reference numerals 25 and 26 denote locks of the heat resistant belt 21, which are driven by a solenoid 27 and a gear motor 28, respectively. The sensor 25a detects the lock open / closed state of the lock 25. The lock 25 in the state shown in FIG. 2 does not cover the sensor 25a, and the sensor 25a is locked by the lock 25.
Detects that the lock is closed. Sensor 2
6b detects that the lock 26 is in the open / closed position.
The lock 26 in the state shown in FIG. 2 does not cover the sensor 26b, and the sensor 26b detects that the lock 26 is in the lock closed state. Reference numeral 29 is a fan for cooling the heating roller 14 in an emergency.

The surface temperature of the heating roller 14 and the heat-resistant belt 21 is heated by an electric heater 17 during sterilization, and by controlling the heater 17 to be turned on / off, a temperature required for sterilization, for example, between 160 ° C and 240 ° C. It is designed to be kept at.

When the banknotes are sterilized, the banknotes pass through the heating section, so that the heating roller 14 and the heat-resistant belt 21 are deprived of heat by the banknotes passing therethrough, and the surface temperature is lowered.
Maximum number of deposits / withdrawals per transaction (eg 100
If the surface temperature of the heating roller 14 when the first banknote passes through the sterilization unit as shown in FIG. The temperature of the heating roller 14 and the heat-resistant belt 21 does not fall below the sterilization temperature lower limit, for example, 160 ° C. If the capacity of the power source heater 17 is increased, the number of sheets that can be continuously sterilized is increased. In order to prevent the temperature from falling below the lower limit of the sterilization temperature, a large-capacity electric heater is required, which poses a practical problem when considering power consumption and mounting.

As for the upper limit of the sterilization temperature, it can be sterilized any number of times as long as it is 160 ° C. or higher, but the higher it is, the more stress is applied to the heating roller 14, the heat resistant belt 21 and other members constituting the sterilization unit. . Therefore, the upper limit of the sterilization temperature is the lower limit of the sterilization temperature, eg, 160 ° C., which is the minimum temperature difference required for continuous sterilization, eg, 80 ° C. 24
The temperature may be 0 ° C. The heat-resistant belt is stretched with a tension of 16 Kgf or more necessary for sterilizing bills, and the heating unit 22 further has a time required to sterilize bills within the above sterilization temperature and heat-resistant belt tension, for example, 0.05 seconds. The bill is heated. When sterilization was performed under such conditions (sterilization temperature, belt tension, heating time), 80% or more of the bacteria adhering to the banknote could be sterilized by experiments for Staphylococcus aureus. .

Next, a schematic process for sterilizing bills will be described with reference to the flowchart of FIG.

Since it takes time to heat the heating roller 14 and the heat-resistant belt 21 constituting the bill sterilization unit from room temperature to a predetermined temperature for sterilization, it is necessary to heat them to some extent in advance. Therefore, after turning on the power of the automatic teller machine (step 32), the electric heater 17 is turned on at (3
3) The temperature of the heating roller 14 and the heat resistant belt 21 is set to a temperature lower than a predetermined temperature for sterilization, for example, about 100 ° C. The temperature is raised to the preheat temperature and waits until the preheat temperature is reached (step 35). At the time when the preheat temperature is reached, the surface temperature of the heating roller 14 and the heat resistant belt 21 is kept constant while turning on / off the electric heater near the preheat temperature. Preheating temperature holding control for holding is started (step 36). Further, if the heat-resistant belt 21 is kept stopped during the above-mentioned standby for preheating, heat may be applied to only a part of the heat-resistant belt 21 for a long time and may be damaged. Therefore, the heating roller 14 and the heat resistant belt 21
It is desirable to always keep the machine in a rotated state. Therefore, after the electric heater is turned on (33), the heating roller 14 and the heat resistant belt 21 are rotated (34). At this point, the heating roller 14 is rotated only to prevent the heat-resistant belt 21 from being damaged, so it is sufficient to drive the heating roller 14 at a lower speed than usual. Heating roller 14 and heat-resistant belt 2
During the rotation of 1, it is checked that they are always rotating, and if they are not rotating, it is judged as abnormal and the electric heater 17 is turned to O.
FF is performed to prevent damage to the heat resistant belt 21 during step out. During this preheating temperature holding control, the conveyance path other than the heating roller 14 and the heat resistant belt 21 is stopped.

The sterilizing unit waits in this state, waits for the transaction for sterilizing banknotes to start (37), and when a transaction for sterilizing banknotes, for example, a dispensing transaction, is selected, the heating roller 14 and the heat-resistant belt are selected. While heating 21 to the sterilization temperature, the drive speed of the heating roller 14 is accelerated to a speed at which bills can be conveyed, and sterilization conveyance control (38) for sterilizing the bills is executed. When the sterilization conveyance control (38) is completed, the preheating temperature holding control (39) for returning the surface temperature of the heating roller 14 and the heat resistant belt 21 to the preheating temperature and holding the temperature is again activated, and then a transaction for sterilizing bills is started. Wait (3
7).

Next, the details of the above-mentioned sterilization / conveyance control (38) will be described with reference to the flowchart of FIG.

When a transaction for sterilizing banknotes is selected, the electric heater 17 is turned on (40) to raise the heating roller 14 and the heat-resistant belt 21, which were held at the preheating temperature up to that point, to the sterilization temperature, and the heating roller 14 is heated. And heat-resistant belt 2
Wait for the temperature of 1 to reach the sterilization temperature upper limit (41). When the upper limit of the sterilization temperature is reached, the sterilization is possible. Therefore, the rotation speed of the heating roller 14 is increased to make the banknote transportable (42), and the banknote transport paths 2, 4 shown in FIG.
6 and 7 are also driven (43). At this time, the heating roller 14
Since the temperature of the heat-resistant belt 21 is already at the upper limit of the sterilization temperature, the electric heater 17 should normally be turned off, and when the temperatures of the heating roller 14 and the heat-resistant belt 21 have dropped to the lower limit of the sterilization temperature, turn on the electric heater 17 again. However, if the banknotes are passed through the sterilization unit, the heating roller 14 and the heat-resistant belt 21 will lose a large amount of heat due to the banknotes passing therethrough, and it is predicted that the temperature will drop significantly.
Is ON. However, if it exceeds the upper limit of the sterilization temperature, it is turned off. In this state, the gate 10 is turned on (44), the separation mechanism (not shown) of the denomination box 8 or 9 is driven, and the banknote separation is started (4).
5). The banknotes separated by the separating mechanism are sent to the transfer path 2 one by one at a constant interval and are transferred to the banknote sterilization unit 11. The banknotes transported by the transport path 2 are switched to the sterilization route by the gate 10 provided on the transport path 2 and transported to the sterilization unit 11. The banknotes are sent to the heating unit 22 between the heating roller 14 and the heat-resistant belt 21 by the conveyance path 30 of the sterilization unit 11. Here, the banknotes are heated while being held between the heating roller 14 and the heat-resistant belt 21 heated to a temperature of 160 ° C. to 240 ° C. It is sent to the path 31, returns to the transport path 2 again, passes through the discrimination unit 3, and transport path 4,
After 7, the money is sent to the deposit / withdrawal port 1 and withdrawn.

By the above operation, the bills are separated and sterilized one by one, and the termination process is performed after waiting for the predetermined number to be separated (46). During this period, it is monitored whether the temperature of the heating roller is below the sterilization temperature lower limit. (47). When the selected transaction is a transaction of 100 sheets or less such as a withdrawal transaction, the temperature of the heating roller does not become lower than the lower limit of the sterilization temperature, so that the process branches directly to 46 and the separation is stopped (54). After waiting for the last separated banknote to reach the sterilization unit (55), the gate 10 is turned off (56), and the last banknote passes through the sterilization unit and reaches the deposit / withdrawal port 1 shown in FIG. (57) Transport paths 2, 4, 6, and 7 are stopped (5)
9) Do. Further, the heating roller 14 is switched to low speed driving (58), the electric heater 17 is turned off (60), and the temperatures of the heating roller 14 and the heat resistant belt 21 are lowered. After the above operation is completed, the preheating temperature holding control (3
9) is started to end the transaction.

As described above, in the dispensing process, the sterilization unit is configured so that the temperature of the heating roller 14 and the heat-resistant belt 21 does not become lower than the lower limit of the sterilization temperature. When the banknotes pass through the sterilization unit continuously for a certain number of times between 21 and 21, the temperature of the sterilization unit may be lower than the lower limit of the sterilization temperature. For this reason 47
If the temperature of the heating roller becomes equal to or lower than the lower limit of the sterilization temperature during the sterilization process, the separation from the separation unit is temporarily stopped (4
8) Wait for the last separated bill to reach the sterilization unit (49), turn off the gate 10 (50), and wait for the last bill to pass through the sterilization unit and be stored in the cassette 12. (51) The conveyance paths 2, 4, 6, 7 are stopped (53), the heating roller 14 is switched to low speed drive (52), and the bill sterilization process is interrupted. In this state, since the electric heater 17 is still in the ON state, the bill sterilization process is started again after waiting for the temperatures of the heating roller 17 and the heat-resistant belt 21 to recover to the sterilization temperature upper limit in (41), and When the banknote sterilization process is completed, the process branches to the completion process at (46). When there are a large number of sterilized banknotes, the banknote sterilization is repeated in the above process.

Although the separation is completely stopped in the above process, the separation speed is reduced to reduce the number of bills fed between the heating roller 14 and the heat-resistant belt 21 per unit time. The heating roller 14 and the heat-resistant belt 21 are prevented from lowering in temperature, and not only the separation speed is decreased but also the conveyance speed of the conveyance path 2 is reduced and the rotation speed of the heating roller 14 is reduced. It is also an effective means to prevent the temperature of the belt 14 and the heat resistant belt 21 from decreasing.

Next, a process when an abnormality occurs in the sterilization unit during the sterilization process will be described with reference to FIG. If the bill remains in the heating unit 22, the bill may be damaged if it is in contact with the heating roller 14 for a long time. Therefore, the power supply of the lock solenoid 27 is turned off when the bills are accumulated and the lock 25
The heat-resistant belt 21 is disengaged and the bills retained in the heating unit 22 are released. Lock 25 of heat resistant belt 21
When is released, the fan 29 installed above the heating roller 14 is rotated to urgently cool the heating roller 14. Further, by rotating the fan 29, there is also an effect that the bills remaining near the heating unit 22 are wiped off.
Further, the heat-resistant belt 21 in the opened state is automatically closed and the initial state can be restored to the locked state. Details of the opening / closing control of the heat resistant belt 21 will be described below with reference to FIG. 7.

Normally, in the standby mode, the lock 2
5 is fixed by a lock stopper 26, and a lock lever 26a supporting the heat resistant belt 21 is held by a lock 25 while supporting the heat resistant belt 21. (Standby Mode) When the dispensing operation is started, the lock solenoid 27 is turned on to hold the lock 25 and the stopper motor 28 moves the lock stopper 26 to the open position. As a result, the lock 25 comes into a closed / open state in accordance with the ON / OFF state of the lock solenoid 27. (Operation mode
D) If an abnormality occurs in this state, the lock solenoid 27 will turn off.
The FF is performed and the lock 25 is opened. As a result, the lock lever 26a is released and the heat resistant belt 21 is released.
(Open state) In this state, the heating roller 14 and the heat-resistant belt 21 continue to rotate by a predetermined amount and stop after all the bills already sent from the gate 10 to the sterilization unit are opened.

When the conveyance path is stopped, residual bills and the like are removed, and then the heat-resistant belt 21 is closed. (Closing process) When the lock stopper motor 28 is rotated by a predetermined amount, the lifting bracket 28a rotates to move the heat resistant belt 21 to the closed position, and the lock lever 26a causes the heat resistant belt 2 to move.
Move to a position that supports 1. In this state, the lock solenoid 27 is turned on, and the lock 25 locks the lock lever 26a. In this state, the stopper motor 28 is rotated in the reverse direction so that the lock stopper 26 is closed and the lock 25 is fixed. Even if the lock solenoid 27 is turned off in this state,
The lock 25 is supported by a lock stopper 26, and the standby mode is set.
It will be in a dead state. (Standby Mode) In the above, the sterilization unit for sterilizing the banknote is composed of the heating roller 14 and the heat-resistant belt 21 arranged so as to surround it as shown in FIG. As shown in FIG. 2, the heating roller 14 and a plurality of rollers 6 facing the heating roller 14 are shown.
Even if it is configured by 1a to 61g, the bill passing through the heating unit 22 is sufficiently wrapped around the heating roller 14 and heated, so that the same effect as that constituted by the heating roller 14 and the heat resistant belt 21 can be expected. . That is, the bill is pressed against the heating roller 14 at a certain angle or more and sent.

[0039]

According to the present invention, the temperature of the heating roller and the heat-resistant belt is always kept at the lower limit of the sterilization temperature or higher while the bill passes through the heat sterilization unit and the sterilization process is performed, so that the bill can be surely sterilized. It becomes possible to do.
