Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a banknote processing device used in a vending machine, a money changer, or the like.

(B) Prior Art In recent years, there has been an increasing demand for vending machines and money exchange machines that accept high-value banknotes and dispense low-value banknotes as change or exchange money. As described above, a banknote processing device capable of processing two types of banknotes has a structure in which one type of banknote is stored in an escrow section, and when there is a request for return of the banknote, it is taken out from the escrow section and dispensed. Japanese Unexamined Patent Publication No. 59-16
There is a device shown in Japanese Patent No. 094. In the device disclosed in this publication, it is impossible to dispense a large amount of bills because the bills to be dispensed are covered only by the inserted bills, and it is not suitable as a device for dispensing change coins or currency exchange coins. Therefore, a loading function is essential for a banknote processing device that dispenses banknotes as change or exchange money. However, loading in a banknote processing device is generally performed by replacing the banknote cassette that is filled with supplementary banknotes in advance. This method is complicated, and also requires a storage section for storing input banknotes separately from the cassette, resulting in an increase in the size of the device.

(C) Purpose of the Invention The present invention provides a banknote processing device that allows loading of banknotes from the insertion slot.

B) Structure of the Invention The present invention allows at least two types of banknotes, high and low denominations, to be inserted into the insertion slot, a banknote identification unit determines the suitability and type of the inserted banknotes, and low denomination banknotes are stacked in a banknote stacking unit. At the same time, high-value banknotes are received in the banknote storage section, and when loading banknotes by operating the banknote loading switch, the recognition accuracy of the banknote recognition unit is lowered to ensure that banknotes inserted from the insertion slot are not low-denomination banknotes. When the banknote identification unit determines that the banknote is present, the banknote is returned from the insertion slot,
The bill is configured such that when the bill identifying section determines that the bill is a low denomination bill, the bill is introduced into the bill stacking section.

(E) Embodiment FIGS. 1 and 2 show a side sectional view and a plan view, respectively, of a banknote processing apparatus according to the present invention. A transfer device (2) communicating with a banknote insertion slot (1) provided externally in the case (IQ) is equipped with a pair of retraction rollers (111 (13) at the rear of the insertion slot (1), and a retraction roller α and the output shaft of the deceleration motor Q3 (14
An endless bell (17) is strung between the driving roller a9 and the guide roller mounted on the rollers 08 (19 (
2I is arranged to rotate as the belt α force moves.

The transfer device (2) includes a pair of retraction rollers, (11) (
12 and guide roller a6) to form a banknote transport path, and sensors (69aX69b) (69c) for measuring the length of transported banknotes and a detection head Cυ for detecting magnetic patterns are arranged in the middle of the transport path. are doing. Sensor (69a
) (69b) (69c) and the detection head (21) constitute a banknote identification section together with an identification circuit that will become clear later.
Identify the suitability and type of banknotes being transported. A shaft (2
A guide piece (c) is provided which can swing freely using the axis as a fulcrum, and a guide bell (C24) is further provided opposite the guide piece (c). Insert a relatively weak spring (
C) is energized. In addition, the guide bell (04) is suspended between a pair of pulleys (2!3) attached to the rotating shaft (5) and the supporting shaft, respectively, which are linked to the deceleration motor. 5) is equipped with a pulley (arm C34, which has a fixed arm 681 and can rotate around the shaft (5) as a fulcrum). A belt (c) continuous to the guide belt (24) is stretched between them to form a conveying device (6).

The banknote stacking section (8) that holds low denomination banknotes is connected to the guide wall (3
) is provided facing the bells L & I, and the earthen wall (G) and six lower walls form a space in which banknotes are stacked in a state in which they are alternately shifted one by one in the longitudinal direction. It is pressed and held against the guide wall (3) by the partition plate which is biased by a spring. As shown in Fig. 3, the guide wall (3) has an opening (4) in the center that corresponds approximately to the autumnal equinox, and a notch (40k) formed in the side edge of the wall (40K). Rollers 0υ are arranged to reduce sliding friction.The stack plate (42 is equipped with a guide part (44) that slides on the guide pin 09 fixed to the housing (10), and usually has a spring (4 The cams (47A) (47B) which press the stack plate (44) against the spring (451) are pressed by the deceleration motor (47B). 46) is fixed to the rotating shaft (c) and support shaft (a) connected to the A belt holder is stretched. As the cams (47A) and (47B) rotate, the stack plate (421) moves in the direction of the opening (4) and is held between the belt (to) and the guide wall (3). A pair of upper and lower claw members (48) (41&-1) hold the stored banknotes in the banknote stacking part (8). ,
It is supported by a rotating shaft 15253 mounted on the side plate 6D, and the respective claw members (4gl (4!It) are set so that their rotational angles are shifted by 180 degrees as shown in FIG. The rotating shaft is directly connected to a deceleration motor 54), and a timing belt 57) is stretched between pulleys attached to the rotating shaft 6, respectively. The claw member (48) performs periodic rotation with a shift of 1180 degrees.
The positions where 0 (49 rotates and comes to rest) are as shown in FIGS. 4, 5, and 6. There are three states: one in which it extends outward and the other in which it extends towards the opening (4).Therefore, the rotation of the rotation shaft (5) causes the claw member (41 (49) to In order to detect the moving position, a cam (not shown) is attached to the rotating shaft 62, and a switch is used to detect the rotating position of the shaft (52).The locking member t5 is rotated. Although it is freely pivoted, it is normally biased in the direction of the claw member (4υ) by a torsion spring Iυ.

The locking member (to) moves against the torsion spring 61) due to the rotation of the cam. At this time, the shaft to which the cam 2 is attached is synchronized with the rotation shaft 53 by a predetermined gear mechanism (not shown). It is configured to rotate.

Similarly, locking members 6 and 1 are rotatably supported.
The torsion spring is biased in the direction of the claw member (to), but the torsion spring is also attached to the shaft which rotates in synchronization with the rotation shaft 5 by a predetermined gear mechanism. Move against the haze. In addition, the end of the arm (toward) on the side biased by the spring c3 group supports a pulley υ and a roller (9), and the other end supports a solenoid fixed to the housing a. It is connected to the operating rod in (g). The roller (9) is rotated by a belt stretched over the transfer device (2) K guide (takeout device, pulley handle) υ for transferring the top banknote of the banknote stack section (8) when dispensing low banknotes. do. In addition, the pulley and bell attached to the shaft) (9
A shaft (93) is equipped with a pulley (92) which is connected to a pulley (92).
4) Rotates by coming into contact with the delivery roller σ which is rotatably supported. A banknote storage unit for high-value banknotes is arranged behind the delivery rollers σ0)ffη.

The operation of the above configuration will be explained. First, when a banknote is inserted into the insertion slot (1), the banknote is taken into the transfer device (2) by the conveying operation of the belt αη caused by the rotation of the drawing roller (IIIH). The detection head (21) generates a detection force corresponding to the passing banknote, and the above-mentioned identification circuit determines the suitability and type of the banknote.The identification circuit determines whether the banknote is unsuitable. When it is determined that
) and returned to the outside of the aircraft. On the other hand, if the bill is correct, when the tip of the bill reaches the sensor (69c) consisting of a set of LEDs and a phototransistor, the deceleration motor (20) is driven and the bill is moved between the belt (c) and the guide wall (3). The banknote is taken into the banknote receiving path (5) formed between one side of the banknote.If the banknote is a high-value banknote, the banknote (331) continues to be driven, so after being conveyed in the receiving direction, The banknotes are introduced into the banknote storage unit by the delivery roller σB.The deceleration motor 2e stops the banknotes after a predetermined period of time after the trailing edge of the banknotes passes through a sensor 6 consisting of a set of LEDs and a phototransistor. .

In addition, if the banknote is a low denomination banknote, when the banknote passes the sensor (to), the drive of the belt (c) is stopped and the banknote taken into the banknote receiving path (5) is guided to the banknote stacking section (8). (
However, there are two timings for stopping this conveyance. That is, the banknote stacking part (8) holds adjacent banknotes in a state in which they are alternately shifted in the longitudinal direction, but as shown in FIG. When the low-denomination bill is held by the belt, the deceleration motor (c) is immediately stopped as soon as the rear end of the low-denomination bill taken in by the belt (c) passes through the sensor 9, and the claw member (c) and locking member 1
58, when the upper end of the stored banknote is clamped,
The rear end of the bill taken in by the belt (c) is connected to the sensor (
The deceleration motor (c) is stopped after a slight delay time after passing through (to). Now banknote stack part (8)
Assuming that a low-denomination bill is taken in by the belt (C) while the banknote inside is being held by the claw member (481) and the locking member (C), after the banknote σj finishes passing through the sensor 6I, In order to stop the motor (c) after the delay time, the banknote σ is taken in to a position where its leading end approaches the lower wall c37) of the banknote stack part (8). Then, the deceleration motor 154) is driven to rotate the rotary shaft (52) 90 degrees counterclockwise, and the claw member θ is rotated 90° counterclockwise as shown in FIG.
B (41) is extended in the direction of the opening (4).At this time, in conjunction with the rotation of the rotating shaft 52153), the locking member (to) is rotated 90 degrees clockwise. (59
1 exits behind the partition plate 0ω. Therefore, the suppression of the claw member (4e (41) and the locking member 6 (to) (5ω) on the stored banknotes in the banknote stacking part (8) is all released.

FIGS. 7 to 10 are cross-sectional views showing the operation of pushing low-denomination bills into the bill stacking section (8).

In the standby state shown in Figure 7, the stack plate Ω is the opening (4)
The banknote 04) which has been exited from the banknote stacking section (8) and is to be stored in the banknote stacking section (8) is held between the pallet l and the roller 0υ.

Then, as the cam (47) rotates due to the drive of the deceleration motor (46), the guide portion (4) of the stack plate (6) is rotated by the cam (47).
47), the stack plate (42 advances through the opening (4) into the banknote stack part (8) and the spring (towards)) as shown in FIGS. 8 and 9.
Push the banknote against the Then, when the cam (47) rotates once and it is confirmed that the cam (47) fixed on the same axis and the position detection switch (Aya) return to the starting position, the deceleration motor (46) is stopped. Transfer device (
2) When the belt (to) has finished taking in the low-denomination banknote introduced from 2), the deceleration motor (c) is rotated once to introduce the banknote to the banknote stacking section (8).

Then, when the deceleration motor 64) is driven to further rotate the rotating shaft 5253) by 90 degrees counterclockwise, the claw member (4 false) extends inward of the banknote stacking part (8), and the rotating shaft ( The locking member 6 projects in the direction of the partition plate 0!J by the rotation of the cam 67) interlocked with the banknote 5. Therefore, the banknotes stored in the banknote stack part (8) are separated from each other as shown in FIG. The lower end portion is held between the claw members (four barrels) and the locking member shaft, but at this time, the claw members (four barrels) and the locking member (A) are open.

However, when the next low-denomination bill is conveyed by Pell) C (3) in this levered state, the motor (C) is immediately stopped when this bill passes through the sensor (To), so the bill is The end portion is taken in only to a position slightly away from the earthen wall (g) of the bill stacking section (8). After that, the rotating shaft 6
Rotate 26 shallow 90 degrees clockwise and attach the claw member (4E9 (
49) and the locking member f5861 to the state shown in FIG. 5, and further rotate the cam (47) once to push the banknote into the banknote stack part (8). Then, the rotating shaft (53) is further rotated clockwise by 90@, and the upper end of the banknotes stored in the banknote stacking part (8) is clamped by the claw member (481 and the locking member C5Q).

As described above, each time a low denomination bill force is introduced, the banknote stacking part (8) stacks the banknotes in an alternately shifted state, and also allows one of the claw members (4S (491) to The banknotes are configured to extend to the top and come into contact with one end of the banknotes stacked on top.

Next, the operation of taking out low denomination banknotes from the banknote stack section (8) will be explained. By the way, since the uppermost banknote in the banknote stack section (8) is held by the claw member (4a (49)), the uppermost banknote is first switched by switching the claw member in order to make it free. As shown in Fig. 4, the switching operation when the stored banknotes are held between the plate and the 5 rods of the locking member is to rotate the respective rotating shafts 180° counterclockwise to the maximum. While the upper banknotes are made free, the second and subsequent banknotes are held by being held between the claw member (49) and the locking member (5) shown in FIG.

Conversely, when the stored banknotes are being held between the claw members (4I locking member r59), the switching operation is to rotate the rotary shafts (5663) by 180° clockwise to free the highest banknotes, and , the second and subsequent banknotes are attached to the claw member shown in Fig. 4 (
It is held in a state where it is held between the mark 4 and the locking base 6. After freeing the highest banknotes in this way,
As shown in FIG. 11, the deceleration motor 63 is reversed to move the bell Fαη in the return direction, and the deceleration motor (
C) and rotate the roller (9) clockwise.

Next, the solenoid (to) is energized to rotate the arm in the direction of the arrow, and the roller (9) is pressed against the surface of the free top bill σD and moved in the direction of the guide piece (c). energize. Therefore, the banknote σ7) moves while being guided by the surface of the guide wall (3) on the side of the banknote stacking part (8), and its tip pushes away the guide piece (C) against the spring (B) and pushes the transfer device ( 2) reaches the guide roller holder. The bill ση is then conveyed toward the insertion slot (1) by the bell) Q7), but when it passes the sensor (69C), the solenoid (G) and the deceleration motor Qe are deactivated and the bill stack part (8) is transported. Stops the operation of taking out banknotes from the machine.

Also, for the reverse operation of the deceleration motor H, the banknote ση is the insertion slot (1).
This continues until it is ejected from the aircraft.

FIG. 12 shows the control circuit configuration when the banknote processing device having such a configuration is applied to a vending machine, where the teeth indicate the banknote processing device side circuit section, and (101) the control circuit of the main body of the vending machine. . The processing circuit (102) of the banknote processing device side circuit section (2) is connected to the main body control circuit (101) of the vending machine by a signal bus (109), and the signal bus (109) allows low denomination banknotes to be exchanged between the two. Number of pieces data・
A sales end signal, a return signal, a low denomination bill payout signal, and a payout end signal are exchanged.

The processing circuit (102) is connected to the control signal line (107).
Control signals are given to each drive motor and solenoid of the banknote processing apparatus through the banknote processing apparatus, and detection signals from each sensor are inputted. The identification circuit (104) is connected to the sensor (69a
The suitability and type of banknotes are determined based on the detection power a@bec of X69b) (69c) and the detection power from the detection head'' (2]), and it is connected to the signal bus (103) for determination. Outputs banknote type data and sends it to the main body control circuit (
101) and a processing circuit (102), and at this time, if the banknote is a low denomination banknote, the trap outputs a count signal to the counter (106). FIG. 13 shows a specific configuration example of the identification circuit (104), in which the inverted output of the detected power a and the detected power a by the inverter (113) are input to the AND gate (111), and the AND gate ( The inverted output of the detection force C by the inverter (114) and the output of the AND gate (111) are input to the inverter (112), and the magnetic detection force d from the detection head (21) is input to the waveform shaping circuit (115).
) is used to shape the waveform at a predetermined level, and its output is counted by a counter (116), and the determining section (110) determines the length of the inserted bill based on the output of AND game (112), and then counts the output of the counter (116). The authenticity of the printed pattern is determined based on the counting data. According to this example, if a low denomination bill is inserted and its length is appropriate,
At the time when the trailing end of the banknote passing through the sensor (69b) has finished passing through the sensor (69a), the leading end has not yet reached the sensor (69c). Therefore, as shown in FIG. 14, only the sensor (69b) detects the banknote and generates a detection force a at the HM level, and the other sensors (69a) (69b) generate a detection force a at the "H" level.
If not, the AND gate (112) produces an "H" level output, and the determining section (110) determines that a low denomination bill is being inserted. In addition, the waveform shaping circuit (118), as shown in FIG. 1
16) counts the number of signals exceeding the reference level A/L1, and determines whether the counting data of the counter (116) has reached the appropriate counting data for each low-denomination and high-denomination bill set in advance. The suitability and type of the inserted banknotes are determined based on the printing pattern. For the same banknote, the determination unit (110) determines that the banknote is appropriate when the type determination based on the length and the 'S type determination based on the printing pattern match.

Further, when the bill loading switch (105) is operated, the processing circuit (102) enters the bill loading mode, and the discrimination accuracy of the discrimination circuit (104) is switched to a low level by a predetermined discrimination control means. Identification circuit (104)
There are various ways to reduce the identification accuracy of banknotes. For example, normally the banknotes are determined based on both the length and the printing pattern, but in the banknote loading mode, the banknotes are determined based on only one of them.
Alternatively, there is a method of lowering the criteria for determining the print pattern. In this example, the waveform shaping circuit (118) is equipped with a switch (
117) is provided as an identification control means, and a switch (117) is provided as an identification control means.
) is turned ON to lower the reference level to the level L determined by the resistors R1 and R1, thereby lowering the print pattern judgment criteria, which increases the count data of the counter (116). The rate at which banknotes are determined to be proper banknotes increases. Therefore, even a banknote whose surface is extremely dirty, a banknote that is partially damaged, or a banknote that has ink or the like applied is determined to be a valid banknote. In addition, in a method in which the magnetic detection force signal is directly counted by a counter (116) and this counting data is compared with preset appropriate counting data to determine the printing pattern of the inserted bill, the bill loading switch By the operation (105), the identification control means switches the identification accuracy to a low level by expanding the allowable range of comparison and discrimination.

In the above control circuit, when the identification circuit (104) determines that the banknote inserted through the insertion slot (1) is a low-denomination banknote, a count-up signal is supplied to the counter (106) to count up the number of low-denomination banknotes. is added, and the banknote stacking section (8) of the banknote processing device is automatically replenished with low denomination banknotes. The identification circuit (104) determines that the inserted banknote is a low denomination banknote.
), the main body control circuit (1
01) adds this amount to the input amount and performs predetermined sales control. Further, when the type data from the identification circuit (104) indicates that the inserted banknote is a high-value banknote, the main body control circuit (101) determines whether or not to accept this high-value banknote in the banknote stack. The determination is made based on the data on the number of low denomination banknotes in section (8) and the relationship with the sales price of the product.

That is, if there are no low-denomination bills to pay out the difference between the double amount of the inserted paper and the selling price, the main body control circuit (101) determines that change cannot be paid out and sends a return signal to the processing circuit (102).

When this return signal is introduced, the processing circuit (102) outputs a reversal signal to the deceleration motor (13) through the control signal line (107), in the same way as when the inserted banknote is returned because it is invalid. Return the banknotes.

However, if it is acceptable to insert large denomination banknotes, the banknote storage area (
7), the main body control circuit (101) adds and counts these banknotes and performs predetermined sales control. When a product is sold on the vending machine side and change is required, the main body control circuit (101) sends a low-denomination bill payout signal to the processing circuit (101).
02). At this time, the processing circuit (102) sends a series of signals necessary for the roller (9) serving as the takeout device to take out the low denomination banknotes from the banknote stack section (8) and guide them to the transfer device (2) through the control signal line. (107) to output to the banknote processing device. That is, the processing circuit (102)
A drive signal is output to the deceleration motor r54) that drives the rotary shaft 25 (9) to free the top bill in the banknote stack section (8), and an energizing signal is output to the solenoid □□□, and the deceleration motor (Output a reverse rotation signal to 2e to rotate the roller (9) clockwise.

The processing circuit (102) then transfers the low denomination banknotes taken out from the banknote stack section (8) to the insertion slot (1) by the transfer device (2).
The processing circuit (102) outputs a reversal signal to the deceleration motor (1) through the control signal line (107) to rotate the belt (17). When the low denomination banknotes taken out from the banknote stack section (8) are ejected from the insertion slot (1) under such control, the processing circuit (102)
outputs a countdown signal to the counter (106) to subtract 1'' from the number of low denomination bills, and outputs a payout end signal to the main body control circuit (101).

When the payout end signal is input to the main body control circuit (101),
The multiplied amount of ejected paper is subtracted from the calculated change amount, and the above-mentioned operation is repeated if it is necessary to pay out further low-denomination bills.

When the banknote loading switch (105) is operated, the processing circuit (102) enters the loading mode, and when a low-denomination banknote is inserted into the insertion slot (1), it is loaded into the banknote stacking section (8), and when banknotes other than low-denomination banknotes are Once inserted, it is returned through the insertion slot (1).

Therefore, the processing circuit (102) comprises loading control means for outputting a series of signals necessary for such operation of the banknote handling device. That is, when the identification circuit (iOS) indicates that the loaded banknote inserted from the insertion slot is a low-denomination banknote, the processing circuit (102) outputs the paper from the control signal line (107) corresponding to the sensor. In response to the input of the banknote detection signal, the drive of the deceleration motor (20) is first stopped, and then a drive signal is output to the deceleration motor 64 to make the banknotes stored in the banknote stack section (8) to be IJ-, and then the deceleration is started. A drive signal is output to the motor (46) to push the inserted bill into the bill stacking section (8), and a drive signal is output to the deceleration motor 54) to push the bill into the bill stacking section (at 4ω). 8) It holds the stored banknotes.In addition,
As mentioned above, in order to hold the stored banknotes in the banknote stacking section (8) in a state where they are alternately shifted in the longitudinal direction, the processing circuit (102) immediately activates the deceleration motor 06) every time a banknote passes the sensor (A). Control for stopping the drive of the motor and control for stopping the drive after a delay time are alternately repeated. When the low denomination banknotes loaded into the banknote stacking section (8) pass through the detection head 0υ and are output to the identification circuit (104), the counter (106) counts up and the banknote stacking section (8) receives an output. ) Count the number of stored banknotes. During such a loading operation, the identification accuracy of the identification circuit (108) is set to low by the operation of the loading switch (105). Even old banknotes with marks painted on them can be loaded into the banknote stacking section (8). In general, increasing the identification accuracy of banknotes improves the ability to distinguish between genuine and fake banknotes, but on the other hand, there is an inconvenience that old banknotes are determined to be fake even if they are valid banknotes.

However, when the administrator loads banknotes,
Since all banknotes are valid banknotes, there is no problem even if the recognition accuracy is lowered, so even old banknotes can be loaded and processed effectively. However, when proper banknotes other than low denomination banknotes are inserted during loading, the processing circuit (102) performs control to return the banknotes from the insertion slot (1). That is, a signal bus (10
9), the processing circuit (102) activates the control signal line (10) as in the case where the inserted banknote is invalid and is returned.
7) outputs a reversal signal to the deceleration motor (13) K to operate the transfer device (2), commonly known as a feeding operation, to return high-value banknotes.

(f) Effects of the Invention According to the present invention, there is no need to provide a special loading banknote setting means in order to load banknotes through a normal banknote insertion slot. By making it possible to insert input banknotes and loading banknotes from the same insertion slot,
The storage unit (banknote stack unit) can be shared, the device can be made smaller, and the loading banknotes can be reliably set in the banknote handling device, making the dispensing operation more stable. Moreover, since the identification accuracy of the identification circuit is set to a low level during loading, even old banknotes can be loaded without having to be returned.
