[Table 2]

In FIG. 1 and FIG. 2, a bill dispensing apparatus 11 equipped with a bill cleaning mechanism has the following configuration. The bill cleaning mechanism 6 according to the present invention includes a bill detection unit 7 that detects a state of a bill (a degree of wrinkling of a bill, dirt of a bill) attached to the bill conveyance path 4 through which the bill is conveyed. A heating roller drive motor 9 for driving a heating and sterilizing unit 8 for heating the banknote during bill transport, a heating roller driving mechanism 18 for controlling the heating and sterilizing unit 8, and a temperature detecting unit for detecting the temperature of the heating and sterilizing unit 17. Temperature detection unit 1
Heater O for turning on / off the heater according to the information of 7
An N / OFF unit 16 is provided. As other mechanical parts of the bill dispensing device, bill separation is performed such that bills are separated one by one from denomination boxes 1, 2, 3, and denomination boxes 1, 2, 3 in which bills of each denomination are stored. Unit 15, a bill transport mechanism 14 that uses the pulse motor 5 as a drive source to move bills on the bill transport path 4, and the dispensing port 1 to which the transported bills reach.
Consists of zero. Next, the control unit 13 controls the operation of each of the mechanism parts according to the number of bills for each denomination box received from the upper device 12 and reports the number of bills dispensed for each denomination box to the upper device 12. This control is performed by the control unit 13.
The operation of each unit is controlled according to a program stored therein. Further, the bill cleaning mechanism 6 has a bill judgment memory 19 and manages a detection state of the bill.

Next, a series of bill cleaning mechanisms including a bill payout operation will be described with reference to the control flowchart of FIG. In the following description, the denominations stored in the denomination boxes 1, 2, and 3 are respectively different banknotes, and the payout operation request of the banknote requested by the host device 12 is the denomination box 1, 2,. Pay out one from three,
At the same time, the host device 12 instructs the bill dispensing device on the bill detecting method of the bill cleaning mechanism.

First, the heat sterilizing section 8 is previously heated to a sterilizable temperature. It waits in this state, and pays out bills while maintaining the sterilizable temperature by the heating means (electric heater, heater ON / OFF unit 16) so that the heat sterilizing unit 8 does not deviate from the sterilizable temperature. wait. When the control unit 13 in the bill dispensing device 11 receives the number of sheets to be dispensed for each denomination from the host device 12, the control unit 13 determines whether the temperature is a sterilizable temperature by the temperature detecting unit 17 (step 100). . If the temperature is the sterilizable temperature, the pulse motor 5 is started (step 101), and the bill transport speed of the bill transport path 4 is changed to the Ss value (pps) which is the reference speed value in the transport speed / sterilization temperature table in Table 2. Wait until it reaches (Step 102). When the banknote transport path 4 reaches the Ss value (pps), which is the reference speed, the host device 12
With reference to the information on the banknote detection method, which is the request information from, if the control request is based on the degree of wrinkles of the banknote (step 103), the processing of the degree of wrinkle control of the banknote (step 104) is executed. If the request is not a request for controlling the degree of wrinkles of a banknote, a dirt control process (step 109) for the banknote is executed. Each of the two control processes [a banknote wrinkle degree control process (step 104) and a banknote stain control process (step 10)]
9)], the bill passes through the heat sterilizing unit 8, and the wrinkles are stretched and the bill is sterilized (step 10).
5). The banknote that has been subjected to the wrinkling and sterilization of the banknote is conveyed to the dispensing port 10. Next, it is determined whether the dispensing operation has been performed for all denominations (step 106). If the dispensing operation has not been performed for all denominations, the next denomination box 1 to be dispensed Set 2, 3, and judge whether it is a sterilizable temperature or not [Ss value (pps) which is a reference speed]
Return to (Step 100), the next denomination box 1, 2,
3 starts a dispensing operation. When the dispensing operation is completed from all the denomination boxes 1, 2, and 3, the pulse motor 5 is stopped by the bill transport mechanism 14 (step 10).
7) The heating roller drive motor 9 is stopped by the heating roller drive mechanism 18 (step 108). When the dispensing operation from all the denomination boxes 1, 2, and 3 is completed, the result of the dispensed number is reported to the host device 12, and the control is terminated.

Next, the control of the transport speed and the sterilization temperature based on the degree of the wrinkles of the bill according to the first aspect will be described with reference to the flowcharts of FIGS. 1 and 6 for controlling the degree of the wrinkles of the bill. In the control method of the conveying speed and the sterilization temperature based on the degree of wrinkles of the bill, the bill detecting unit 7 in the block diagram showing the system configuration of the bill dispensing apparatus in FIG. 2 is a sensor for detecting the presence or absence of a bill. 20, a detection mechanism 21 that is set at the same position as the banknote presence / absence detection sensor 20 to change the degree of wrinkles of the banknote into a vertical change amount, and an angle sensor 22 that detects the vertical change amount of the detection mechanism become. Further, as shown in the content table of the banknote judgment memory for each judgment control in Table 1, the banknote judgment memory 19 has a wrinkle degree memory, a judgment wrinkle degree memory, and a conveyance speed / sterilization according to a wrinkle degree amount. Classified into temperature tables.

In FIG. 5 described above, when it is determined that the bill detecting method is controlling the degree of wrinkles of the bill (step 104),
In the wrinkle degree memory for judgment classified in the banknote judgment memory 19, a reference degree value [Ws (mm)] for the degree of wrinkle in the table of the conveying speed / sterilization temperature table in Table 2 is set (step 121). ). Then, one banknote is separated from the designated denomination boxes 1, 2, and 3 by the banknote separation unit 15 (step 122). The separated banknotes pass through the banknote transport path 4 and wait for the banknotes to arrive at the banknote detection sensor 20 (step 123). When the arrival of the bill is detected, the wrinkle amount memory value is set to 0 (step 124). That is, it is set as an initial value. When the bill detecting mechanism 21 moves up and down, the generated movement amount is extracted by the angle sensor 22 (step 125) and converted into a digital value. The greater the amount of movement of the detection mechanism 21, the greater the degree of wrinkling of the bill. Next, the extracted value is compared with the value of the wrinkle amount memory to determine whether the extracted value is large (step 126). If the previously extracted movement amount is greater than the value of the wrinkle degree memory, that is, if the degree of wrinkle is larger than the previous value, the extracted value is rewritten to the wrinkle degree memory (step 129). That is, the maximum change amount of the detection mechanism (the value of the largest wrinkle) is always stored in the wrinkle amount memory. Conversely, if the previously extracted value is smaller than the value of the wrinkle amount memory, the value of the wrinkle amount memory is not rewritten. Then, it is determined whether one bill has passed through the bill detection sensor 20 (step 1).
27). When one bill is still passing through the bill detection sensor 20, that is, while one bill is crossing the bill detection sensor 20 (step 125, step 126, step 129 depending on conditions) repeat. When one banknote has passed through the banknote detection sensor 20, it is determined whether or not the value of the previously set wrinkle level memory matches the value of the wrinkle level memory (step 128). When the determination is NO, that is, when they do not match, based on the value of the wrinkle amount memory,
The transfer speed / sterilization temperature table (the transfer speed / sterilization temperature table in Table 2) set in the banknote determination memory is referred to (step 130). From Table 2, for example, assuming that the value of the wrinkle amount memory calculated last time is the Wm (mm) value, the corresponding transport speed value is Sm (pps).
The sterilization temperature value is associated with the value of Tm (° C.). Then, the transport speed value and the sterilization temperature value are extracted from the table (step 131). Next, a change in speed is set for the banknote transport mechanism 14 according to the extracted transport speed value, and the transport speed of the banknote transport path 4 is changed by the pulse motor 5 (step 132). Similarly, the transfer speed to be changed is set for the heating roller drive mechanism 18 and the speed of the heating roller drive motor 9 is changed (step 13).
3). Next, it is determined whether the sterilization temperature value extracted from the table is lower than the currently set sterilization temperature value (step 134), and the currently set sterilization temperature is calculated based on the sterilization temperature extracted from the table. If lower, the heater is turned on by the heater ON / OFF unit 16 (step 135). If the current sterilization temperature is higher than the temperature set this time, heating is not performed. Then, it is determined whether or not the speed value of the pulse motor 5 and the speed value of the heating roller drive motor 9 have reached the set values and whether or not the set sterilization temperature has been reached (step 136). Execute (Step 136) and wait until the set transport speed value and sterilization temperature value reach. When the transport speed and the sterilization temperature value are reached, the heater is turned off by the heater ON / OFF unit 16 (step 137), and the wrinkle degree control processing of the bill ends.

Next, the control of the transport speed and the sterilization temperature due to the dirt on the bill according to the second aspect will be described based on the configuration of the bill detecting unit in FIG. 3 and the dirt control flowchart of FIG. In the control method of the transport speed and the sterilization temperature due to the contamination of the banknote, the banknote detection unit 7 in the block diagram showing the system configuration of the banknote dispensing apparatus in FIG. 2 is used to determine the presence or absence of the banknote shown in FIG. Presence detection sensor 2
3. A transmission type sensor 24 which is set at the same position as the banknote presence / absence detection sensor 23 and detects the transmission amount of the banknote.
In addition, the banknote determination memory 19 is classified into a banknote permeation amount memory, a banknote contamination amount memory, and a conveyance speed / sterilization temperature table by banknote permeation amount, as shown in the content table of the banknote determination memory for each judgment control in Table 1. Is done.

In FIG. 5, when it is determined that the banknote detection method is banknote dirt control (step 109), the banknote dirt amount memory classified in the banknote determination memory 19 stores the transport speed and the speed shown in Table 2. A reference permeation amount value [Ds (%)] for banknote contamination in the sterilization temperature table is set (step 141). Then, the designated denomination box 1,
One bill is separated from the bills 2 and 3 by the bill separator 15 (step 142). The classified bills are stored in the bill transport path 4
And waits for the bill to arrive at the bill detection sensor 23 (step 143). After detecting the arrival of the bill,
The banknote permeation amount memory value is set to 0 (step 1).
44). That is, it is set as an initial value. Next, the transmission amount of the bill is extracted by the transmission type sensor 24 (step 14).
5) and convert it to a digital value. The higher the permeation, the heavier the banknote is. Then, the extracted value,
By comparing the values in the banknote permeation amount memory, it is determined whether the extracted value is large (step 146). If the previously extracted permeation amount is larger than the value of the bill permeation amount memory, the extracted value is rewritten to the bill permeation amount memory (step 149). In other words, the maximum amount of permeation of a bill (the worst value of dirt) is always stored in this permeation amount memory.
If the previously extracted value is smaller than the value in the bill permeation amount memory, the value in the bill permeation amount memory is not rewritten. Then, it is determined whether or not one bill has passed through the bill detection sensor 23 (step 147). When one bill is still passing through the bill detection sensor 23,
In other words, while one bill crosses the bill detection sensor 23 (step 145, step 146, step 149 depending on conditions) is repeated. When the bill has passed the bill presence / absence detection required sensor 23, it is determined whether or not the value of the previously set bill dirt amount memory matches the value of the bill penetration amount memory (step 148). When the determination is NO, that is, when they do not match, the transport speed / sterilization temperature table set in the banknote determination memory (based on the transport speed / Reference is made to a sterilization temperature table (step 150). Table 2
Thus, for example, the value of the previously calculated bill transmission amount memory is D
Assuming that the value is an m (%) value, the corresponding transport speed value is Sm (pps), and the sterilization temperature value is associated with the value of Tm (° C.). Then, the transport speed / sterilization temperature value is extracted from this table (step 151). next,
A change in the speed is set for the banknote transport mechanism 14 according to the extracted transport speed value, and the transport speed of the banknote transport path 4 is changed by the pulse motor 5 (step 152). Similarly, a change in the conveying speed is set for the heating roller driving mechanism 18, and the speed of the heating roller driving motor 9 is changed (step 153). Next, it is determined whether the sterilization temperature value extracted from the table is lower than the currently set sterilization temperature value (step 154), and the currently set sterilization temperature is calculated based on the sterilization temperature extracted from the table. If it is lower, the heater ON / OFF unit 16 turns the heater ON.
N is performed (step 155). If the current sterilization temperature is higher than the temperature set this time, heating is not performed. Then, it is determined whether or not the speed value of the pulse motor 5 and the speed value of the heating roller drive motor 9 have reached the set values and whether or not the set sterilization temperature has been reached (step 156). Until the aforementioned transport speed value and sterilization temperature value are reached (step 15).
Execute 6) and wait. When the set transport speed and sterilization temperature value are reached, the heater is turned off by the heater ON / OFF unit 18 (step 157), and the banknote soiling control process ends.

In the above, one embodiment of the present invention has been described. In this embodiment, the transfer speed and the sterilization temperature are set to the reference speed value or the reference temperature value for each denomination box in FIG. Although the method of returning is described, it is possible to cope without setting the reference speed value or the reference temperature value every time by providing a table for each determination result for the transport speed and the sterilization temperature that changes each time. .
