Description

Specification

Banknote processing apparatus and control method thereof

The present invention relates to a banknote processing apparatus and a control method thereof, and more particularly to a banknote processing apparatus used for a banknote storing process of a vending machine and the like and a control method thereof. Background art

Generally, devices handling bills, such as vending machines, are provided with a bill handling device for determining the authenticity of bills and storing genuine bills in the machine body. The banknote handling machine performs the denomination judgment and the authenticity judgment of the inserted banknote, and when the inserted banknote is judged to be genuine, stores the banknote and inserts the genuine banknote into a vending machine or the like. FIG. 4 is a side view showing a schematic configuration of the bill processing apparatus.

As shown in the figure, the banknote handling machine 100 is equipped with a bill insertion slot 101, a pulley 102, a bill transport path 103, an identification sensor 104, a stack drum 105, and a cash machine. G 106, sliding force 107, holding plate 108, and coil spring 109.

In the banknote handling machine 100, when a banknote is inserted from the banknote inlet 101, an insertion sensor (not shown) detects the insertion of the banknote, and thereby a transport module (not shown) is driven. The drive of the transport motor drives the pulley 102, which is interlocked with the transport motor, to move the bill into which the transport belt (not shown) stretched along the bill transport path is inserted, along the bill transport path 103.

When the bill moves along the bill transport path 103, the identification sensor 104 detects the features of the bill, and the authenticity of the bill is determined based on the detection result. As a result of the authenticity determination, if the bill is determined to be counterfeit, the transport mode is reversed and the bill is returned from the bill insertion slot 101, and if the bill is determined to be genuine, the transport mode is reversed. Evening continues to rotate normally, and the banknote stops while being sandwiched by slits 105a formed in stack drum 105. You. The stack drum 105 will be described later.

Subsequently, while the stack drum 105 rotates in a predetermined direction, the paper cash 106 moves in the direction of arrow A in the figure, and the bill is accommodated in the paper power 107. A pressing plate 108 is provided for the pressing force 107 via a coil panel 109, and the stored bills are pressed by the pressing plate 108 toward the stack drum 105.

Next, the operation of the stack drum 105 will be described with reference to FIG.

FIG. 5 is a front view of the stack drum 105 as viewed from the scanning force 107 side.

As shown in the figure, the stack drum 105 includes stack drums 105-1 and 105-2, which are arranged in pairs. When it stops at the position of, the slide motor (not shown) is driven to rotate the stack drums 105-1 and 105-2 in the directions of arrows B and C in the figure. In conjunction with the rotation of the stack drums 105-1 and 105-2, the paper chute 106 moves to the near side in the figure, so that the banknote is stored in the stabilizing force 107.

The stack drum 105-1 is provided with a carrier switch 150, and the position of the stacks 105-1 and 105-2 (the position with respect to rotation) is detected based on the state of the carrier switch 150, and the switching power mode is set. Is controlled. Here, the carrier switch 150 will be described.

6 (a) to 6 (c) are top views of the carrier switch 150, respectively, and FIGS. 6 (d) to 6 (f) are shown in FIGS. 6 (a) to 6 (c), respectively. 6 is a side view corresponding to the carrier switch 150. FIG.

The carrier switch 150 includes a rotating unit 151 and a detecting unit 152, and the on / off state of the detecting unit 152 is switched according to the position of the rotating rotating unit 151. For example, when the rotating unit 151 is at the position shown in FIGS. 6A and 6D, the detecting unit 152 is in the off state, and the rotating unit 151 moves from this position in the direction of arrow D in the figure. When 151 rotates, the detector 152 changes to the state shown in FIGS. 6 (b) and 6 (e) with the detector off, and when the rotating part 151 rotates in the direction of arrow E in the figure, it is detected. The outlet 152 is turned on, and the state shown in FIG. 6 (c) and FIG. 6 (f) is obtained. In this state, when the rotating unit 151 rotates in the direction of arrow F in the figure, the detecting unit 152 keeps the ON state, and the position of the rotating unit 151 becomes the position shown in FIGS. When the sensor rotates to the position (d), the detector 15 2 switches off. FIG. 6 (g) shows the relationship between the position of the rotating section 15 1 and the state of the detecting section 15 2.

By using such a carrier switch 150, the stack drums 1055-1 and 1055-2, which rotate each time a banknote is stored, are stopped at the correct position (the position exactly rotated one turn). Like that. To accurately control the stop position of the stack drums 105-5 and 1055-2, its position detection is important. When the carrier switch 150 is used, the carrier drum 150 (detection section 152) is switched from on to off, and the stack drums 1055-1 and 1055-2 are stopped at the same time. However, in practice, the stack drums 105-1 and 105-2, a stack motor (not shown) will rotate due to inertia even after a stop instruction (power off of the stack motor).

For this reason, in the control of the stack motor, the relationship between the stop position and the position at which the detection unit 150 switches from on to off is determined in consideration of the influence of inertia.

Actually, there is variation due to differences in characteristics between products, etc., so when the detection unit 150 is switched from on to off, the timer is activated, and after a predetermined time has elapsed, the power of the sleep mode is turned on. It is configured to shut off, so that the time set for the evening can be adjusted.

FIGS. 7A to 7C are diagrams showing the rotation speed of the stack motor, the power supply state thereof, and the state of the carrier switch 150. FIG.

As shown in Fig. 7 (a), when the carrier switch 150 is switched from ON to OFF, the timer is activated, and when the predetermined time T is measured by the timer, the power of the sleep mode is switched on. When the engine is shut off, the stack motor rotates by inertia and then stops. In this case, the time from when the state of the carrier switch 150 is switched from on to off to the time when the spider stops is TL, the stack drums 105-1 and 105-2 are shown in the figure. Rotate by a distance (angle) L corresponding to the area of the shaded area of However, this is because the time T is set so that the position stopped after the rotation becomes the desired position.

However, the stop position is not always constant because the load of the stack motor changes depending on the temperature, the number of stored bills, the fluctuation of the power supply voltage, and the like. Generally, the load decreases in a high temperature state and increases in a low temperature state.However, vending machines installed outdoors are susceptible to this effect. This may cause paper jams and the like.

When the load decreases, as shown in Fig. 7 (b), the stack motor rotates at a relatively high rotation speed, so that the state of the carrier switch 150 switches from on to off. If the power to the stack motor is turned off after the lapse of the predetermined time T, the time required to stop the operation becomes longer. Therefore, the time from the change of the state of the carrier switch 150 to the stop of the static switch is TL + TL1, and the moving distance between them is the distance L1 corresponding to the area of the hatched portion in the figure. (> L).

When the load increases, as shown in Fig. 7 (c), the stack motor rotates at a relatively low speed, and the state of the carrier switch 150 is switched from on to off. If the power of the stack motor is turned off after a lapse of a predetermined time T from the time, the time required to stop the operation becomes shorter. Therefore, the time from the change of the state of the carrier switch 150 to the stop of the stack mode is TL + TL2, and the moving distance between them is the distance L corresponding to the area of the hatched portion in the figure. 2 (<L).

As described above, in the conventional banknote handling machine, when the load in the stack mode fluctuates due to a change in temperature or the like, the stack drum cannot be stopped at a predetermined position. Had a problem that the banknotes could not be accepted. Disclosure of the invention

Hereinafter, a bill processing apparatus and a control method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

The banknote processing apparatus according to the present invention has basically the same configuration as the conventional banknote processing apparatus, and differs only in the control unit of the stack motor that drives the stack drum. Is omitted.

FIG. 1 is a block diagram showing a configuration of a stack model overnight control unit which is a part of the configuration of the banknote processing apparatus.

As shown in the figure, the stack motor controller includes a carrier SW (switch) detector 1, a timer 2, a timer value calculator 3, a timer 4, and a motor controller 5. The carrier SW detector 1 detects the state of a carrier switch disposed in a stack drum (not shown), and the timer 4 measures the time when the carrier switch detected by the carrier SW detector 1 is on. . Further, the evening ima value calculating unit 3 calculates the time counted by the evening ima 2 based on the on-time of the carrier switch measured by the timer unit 4, and the evening ima 2 calculates the time calculated by the evening ima value calculating unit 3. Count. The motor controller 5 drives the stack motor and stops power supply to the stack motor when the timer 2 counts a predetermined time. Since the rotation speed of the stack motor changes depending on the load condition (large or small), the time from when the stack motor drives to start the rotation of the stack drum until the carrier switch changes its state ( The rotation angle is constant regardless of the load).

Therefore, the timer 4 measures the time until the state of the carrier switch changes from on to off, and based on the result of the measurement, changes the time set by the timer value calculator 3 to the timer 2. Thus, the stop position of the stack drum can be kept constant.

FIGS. 2 (a) to 2 (c) are diagrams showing the number of rotations of the spider, the power supply state thereof, and the state of the carrier switch.

As shown in Fig. 2 (a), when the motor controller 5 starts supplying power to the stack motor, the stack motor rotates and the stack drum rotates accordingly. Changes from off to on. When the carrier switch changes from off to on, the carrier SW detector 1 detects this change, and the timer 4 starts counting time. When the stack drum rotates to a predetermined position, the output of the carrier switch changes from on to off, and the carrier SW detector 1 detects this change. As a result, the timer unit 4 finishes measuring the ON time Tc of the carrier switch, and the timer value calculation unit 3 calculates the count time set in the timer 2 based on the time Tc. The count time calculated by the timer value calculation unit 3 differs depending on the time Tc measured by the timer unit 4.However, the example shown in FIG. calculate. As a result, the timer 2 starts counting the time T, and when the time T is counted up, the motor controller 5 stops supplying power to the stack motor, the stack motor rotates only by inertia, and then rotates. Stop. In this case, the distance (angle) in which the stack drum rotates during the time TL from the time when the output of the carrier switch changes from on to off to when the stack motor stops is L, which corresponds to the area of the shaded area in the figure. Become.

Fig. 2 (b) shows the case where the load of the stack module is light. In this case, similarly, the motor controller 5 starts supplying power to the stack module. As a result, the stack motor rotates and the stack drum rotates accordingly, so that the output of the carrier switch changes from off to on. When the carrier switch changes from off to on, the carrier SW detector 1 detects this change, and the timer 4 starts clocking. When the stack drum rotates to a predetermined position, the output of the carrier switch changes from on to off, and the carrier SW detector 1 detects this change. As a result, the timer unit 4 finishes measuring the ON time Tc1 of the carrier switch, and the timer value calculation unit 3 calculates the count time to be set in the timer 2. At this time, the time T c 1 measured by the timer 4 is shorter than the time T c for the standard load, so the count time calculated by the timer value calculator 3 is the time calculated when the load is standard. The time T—t1 is shorter than T by t1. Therefore, when the timer 2 counts the time T-tl and the timer 2 counts up the time T-t1, the controller 5 stops the power supply to the timer and the stack mode. In the evening, it rotates only by inertia and then stops. At this time, the time from when the output of the carrier switch changes from on to off to when the stack motor stops is TL1, and the distance (angle) at which the stack drum rotates depends on the area of the shaded area in the figure. It is equivalent to L. Therefore, the stop position of the stack drum is the same as when the load is standard.

Fig. 2 (c) shows a case where the load on the spider is heavy.c When the motor controller 5 starts supplying power to the stack motor, the stack motor rotates and the As the stack drum rotates, the output of the carrier switch changes from off to on. When the carrier switch changes from off to on, the carrier SW detector 1 detects this change, and the timer 4 starts counting time. When the suction drum rotates to a predetermined position, the output of the carrier switch changes from on to off, and the carrier SW detector 1 detects this change. As a result, the timer unit 4 ends the measurement of the on time Tc2 of the carrier switch, and the timer value calculation unit 3 calculates the count time set in the timer 2. At this time, the time Tc 2 measured by the timer 4 is longer than the time Tc for the standard load, so that the count time calculated by the timer value calculator 3 is calculated when the load is standard. Is T + t2, which is longer than time T by t2. Therefore, timer 2 counts the time T + t2, When 2 counts up the time T + t2, the motor controller 4 stops supplying power to the stack motor, and the stack motor rotates only by inertia and then stops. At this time, the time from when the output of the carrier switch changes from on to off to when the stack motor stops is TL2, and the distance (angle) at which the stack drum rotates is L, which corresponds to the area of the shaded area in the figure. Become. Therefore, the stop position of the stack drum is the same as when the load is standard.

Next, with reference to FIG. 3, the operation of each unit from the driving to the stop of the stack mode will be described.

Fig. 3 is a flow chart showing the flow of operation of each unit from driving to stopping of the stack motor.

When the bill inserted from the bill insertion slot is conveyed to a predetermined position, the process is started (step 51), and the motor controller 5 starts supplying power to the stack motor (step 52). When power supply to the stack motor is started, the stack motor is driven to rotate the stack drum, and the carrier switch is switched from off to on. The carrier SW detector 1 detects the state of the carrier switch (step 53), and when the state of the carrier switch is switched from off to on (YES in step 53), the timer 4 starts counting time (step 53). Step 5 4). Next, the carrier SW detector 1 waits for the carrier switch to switch from ON to OFF (N〇 in step 55). When the carrier switch is switched from ON to OFF (YES in step 55), the timer 4 counts. End (step 56).

Next, the evening time calculation unit 3 calculates the count time to be set in the evening time 2 based on the result of the time measurement by the timer unit 4 (step 57), and sets the calculated time in the evening time 2 (step 57). Step 5 8). Subsequently, the time when the timer 2 is set is counted (NO in step 59), and when the time is up, the time-up is notified to the motor controller 5 (YES in step 59). Upon receiving the notification of the time-up, the motor controller 5 stops supplying power to the stack motor (step 60), and terminates the bill storing process (step 61).

Note that the timer value to be set for timer 2 can be calculated in advance, The value of the number may be held as a table, and the value may be selected from the table based on the time measured by the timer 4.

Further, in this embodiment, the case where the position of the stack drum is detected by the carrier switch has been described. However, even in a case where the position of the stack drum is accurately detected by another configuration using an encoder or the like. Since the stack motor rotates by inertia after the power supply is stopped, the stop position of the stack drum can be controlled in the same manner as in this embodiment. Industrial applicability

The present invention relates to a banknote processing apparatus that measures a time required for a stack drum to rotate to a predetermined position and calculates a time for stopping a stack mode based on the measured time, and a control method thereof. According to this configuration, the stack drum can be stopped at a predetermined position even if the load fluctuates due to an environmental change such as temperature or an increase in the number of stored bills.
