Description

[Detailed Description of the Invention] (a) Field of Industrial Application This invention relates to a bill storing and dispensing device incorporated in a bill handling section of a vending machine, and particularly for storing and discharging a portion of inserted bills as a change ticket. The present invention relates to a banknote storage and feeding device.

(b) Prior Art Recently, vending machines that sell high-value items and high-value tickets have been installed, but it is necessary to prepare a large amount of change tickets in the vending machines. By the way, the bill storing and dispensing device conventionally used in this type of vending machine has, for example, 1,000 yen, 5,000 yen, etc.
A system has been proposed that accepts and processes three types of banknotes: 1,000 yen and 10,000 yen. In this case, 1,000 yen bills and 5,000 yen bills are prepared and stored in advance as change bills, and a predetermined number of stored bills are released as needed. For this reason, it is necessary to prepare a large number of fishing tags in advance, which not only requires time and effort to replenish the fishing tags, but also causes the stored fishing tags to be consumed one after another, causing the vending machine to run out. There were problems that caused the rate to drop.

Bill storage devices that attempt to solve this problem have been proposed in the past. Japanese Unexamined Patent Publication No. 53-104300 discloses an apparatus for storing a plurality of banknotes by stacking and holding the banknotes while shifting them one after another between two opposing belts. Moreover, in Utility Model Application Publication No. 58-60644, a guide band is stretched between two rollers, and this guide band is used together with banknotes.
A device is shown for storing banknotes by winding them up on rollers.

(c) Problems to be Solved by the Invention However, in the former device, banknotes are stored within a limited distance determined by a limited belt length, so in order to store a large number of banknotes, a very long distance is required. This had the disadvantage that a long belt had to be used, which increased the size of the entire device. Also, in the latter device,
The disadvantage is that a plurality of banknotes are simply held between guide bands, and a large number of banknotes cannot be efficiently stored in a limited space.

This invention solves the above-mentioned drawbacks, and stores the banknotes of the denomination used as a change bill among the inserted banknotes by wrapping and holding them in a stepped manner between the drum circumferential surface and the winding tape. To provide a banknote storage and feeding device capable of eliminating the work of preparing and replenishing change tags, greatly reducing the occurrence of running out of change tags, and improving the operating rate by using the same as a change tag. With the goal.

(d) Means for solving the problem This invention is formed between the bill slot and the flapper,
A front conveyance means including a belt and a motor that clamps the banknotes is arranged with a certain gap between the flapper and the banknote discharge port, and the frictional resistance generated between the banknotes and the banknotes prevents the friction between the banknotes and the banknotes. a pair of belts having a friction resistance lower than that generated between the belts, and a rear conveyance means including a motor; connected to the rear conveyance means by switching the flapper; and a drum, one end of which is fixed to the circumferential surface of the drum. Equipped with a wrapping tape,
When the drum is rotated in reverse, the banknotes on the rear conveyance means are rolled up between the drum peripheral surface and the wrapping tape to be stored, and when the drum is rotated in the normal direction, the stored banknotes are delivered to the rear conveyance means. A banknote storage mechanism is provided at the end of the rear conveyance means on the side of the banknote discharge port so as to be able to come into contact with and separate from the banknote storage mechanism. a feed-out roller for discharging; a first banknote sensor provided near the flapper on the rear conveyance means; a second banknote sensor provided near the feed-out roller on the rear conveyance means; and the first banknote sensor. a first timer for measuring the time required for the rear end of the banknote to pass through the flapper after the banknote sensor detects the leading end of the banknote conveyed through the front conveyance means; After the banknote sensor detects the rear end of the banknote stored in the banknote storage mechanism from the rear conveyance means, the rear end is transported from the first banknote sensor a distance shorter than the length of the banknote in the transport direction. a second timer that measures the necessary time; and a second timer that operates the front conveyance means and the rear conveyance means from the time when the banknote storage signal is input and the banknote is inserted into the banknote slot until the time of the first timer expires. At the same time, the banknote storage mechanism is driven in the forward direction only while the first timer is operating, and when the first timer times up, the flapper is switched and the rear conveyance means and banknotes are operated until the second timer is turned off. a storage control means that drives the storage mechanism in the reverse direction; and a banknote storage mechanism that drives the banknote storage means and rear conveyance means in the forward direction when a change bill request signal is input and when a second banknote sensor is turned on. The second timer is turned off when the change bill request signal is no longer input. and a discharge control means for driving the rear conveyance means and the banknote storage mechanism in the opposite direction until the bill storage mechanism is released.

(e) Effect of the invention With the above configuration, when the inserted banknote is conveyed from the front conveyance means to the rear conveyance means and the first banknote sensor is turned on, the banknote storage mechanism operates in the forward direction and is stored. The deposited banknotes (reserved banknotes) and the inserted banknotes partially overlap. In other words, since the stored banknotes are stopped at a distance shorter than the length of the banknotes in the transport direction from the first banknote sensor, the drive of the stored banknotes is stopped at the moment the inserted banknote is detected by the first banknote sensor. Once started, the stored banknotes and the inserted banknotes can partially overlap. Thereafter, if these are taken into the banknote storage mechanism, a plurality of banknotes can be stacked one on top of the other in order and stored.

Furthermore, when discharging the stored banknotes in response to the input of the change bill request signal, the banknotes at the tip are conveyed until they are detected by the second banknote sensor, and then fed out until the second banknote sensor no longer detects the banknotes. By bringing the rollers into contact with the rear conveyance means,
Only one bill at the tip is discharged from the bill discharge port. After that, when the change bill request signal is no longer input, the delivery roller is separated from the rear conveyance means, and the rear conveyance means and bill storage mechanism are driven in the opposite direction to remove the bills being sent into the rear conveyance means. It is stored in the storage mechanism.

(f) Embodiment FIG. 1 schematically shows a bill storing and dispensing device according to the present invention applied to a bill processing section of a vending machine. Bills inserted into the vending machine are taken in from a bill receiving port 1 through a bill validating section (not shown). The bill validating section determines whether the received bill can be used as a change ticket.
Bills of denominations that are not used as change bills or bills for change bills when the bill storage drum 12 is full and cannot be stored as change bills are held between the belts 4 and 5, and then placed on the belt 7 and conveyed. It is transported to the discharge port 14 side. Here, the conveyance path formed by belts 4, 5, motor 3 (described later), etc. corresponds to the front conveyance means of the present invention, and the conveyance path formed by belts 7, 8, motor 6 (described later), etc. This corresponds to the rear conveyance means of this invention.

The fishing tag storage mechanism consists of a drum 12 and a wrapped tape 15 with one end of the tape fixed to the drum 12. A bill for a fishing ticket is guided between the circumferential surface of a drum 12 and a wrapping tape 15, and is wound and held by the wrapping tape 15. 18 is a supply roller for the winding tape 15, and 19 is its driving motor. 3,6,1
3 is a drive motor for the belts 4, 7 and the drum 12, respectively. Reference numeral 11 denotes a flapper that divides the conveyance path from the banknote receiving port 1 to the discharge port 14 side and the conveyance path from the discharge port 14 to the drum 12 side, and its direction is switched by turning on and off the solenoid 10. Reference numeral 17 denotes a delivery roller that sends out banknotes stored in the drum 12 to the outside from the discharge port 14, and is swung and moved by a solenoid 20. That is, when the solenoid 20 is turned on, the feed roller 17 swings upward and comes into contact with the inside of the belt 7, and presses one of the rollers that tension the belt 8 through the belt 7. The belts 7 and 8 are not in contact with each other when the solenoid 20 is turned off, and a predetermined gap is provided between the belts 7 and 8. When the solenoid 20 is turned on, the belts 7 and 8 come into contact for the first time,
This contact causes the belt 8 to rotate. but,
Even in this state, the belts 7 and 8 are not in contact with each other in the portions that do not face the feed roller 17.
When the solenoid 20 is turned off, the feed roller 17
leaves the belt 8. Detectors 2 and 9 are used to check the passage of banknotes. This detector 9 is the first banknote sensor of the present invention, and its installation position is a predetermined length forward from the front end of the stored banknotes stored in the wrapping tape in the converging conveyance path. This predetermined length is less than the length of the banknote in the conveying direction. Detector 16 corresponds to the second banknote sensor of the present invention.

FIG. 2 is a block diagram of the control section of the bill storing and dispensing device. The control section is composed of a microprocessor system consisting of a CPU 30 and a memory 31. The output of detectors 9 and 16 is AMP32
is given to the CPU 30 through. 33 to 38 are drive circuits for driving and controlling the motors 3, 6, motors 13, 19, and solenoids 10, 20, respectively.

Next, the operation of the above structure will be explained with reference to the flowcharts of FIGS. 3 and 4 and the diagrams showing the banknote storage state of FIGS. 5A to 5F. FIG. 3 shows the operation when storing banknotes, and FIG. 4 shows the operation when paying out banknotes. Moreover, FIGS. 5A to 5F show the states of banknotes at each stage during banknote storage and banknote feeding. Here, 40 is the inserted banknote, 41 (41-
1, 41-2) indicates stored banknotes.

FIG. 3 shows the operation when an input banknote is stored in the drum 12 by inputting a banknote storage signal based on the determination by the banknote control and discrimination section that the banknote is of a denomination that can be used as a change ticket. First, step n1 (hereinafter, step ni)
is simply called ni. ) to reverse the motors 3 and 6 counterclockwise in the figure. Bills for change tags taken in from the bill receiving port 1 by motor drive are conveyed to the detector 9 along the flapper 11 by belts 4 and 5. When the front end of the inserted banknote 40 interrupts the detector 9 (FIG. 5A), a timer A (not shown) owned by the CPU 30 is set, and the motors 13 and 19 are rotated clockwise in the figure. (n2-n4). Note that the timer A is the first timer of the present invention, and is set to measure the time from when the front end of the inserted banknote 40 passes the detector 9 until the rear end of the banknote passes the flapper 11. ing. The reason why timer A is used is because the stored banknotes 41 are fed out between the belts 7 and 8 following the input banknotes 40, as will be described later. This is because it is not possible to detect that the vehicle has passed through and reached the converging conveyance path.

Due to the normal rotation of the motor 13, the drum 12 and the wrapping tape 15 rotate clockwise while maintaining a constant tension, and the stored banknotes 41 are sent out between the belts 7 and 8. At this time, as described above, the motors 13, 1
The normal rotation start timing of 9 is when the detector 9 detects the front end of the input banknote 40, and since the detector 9 is located a predetermined length ahead of the front end of the stored banknote 41 on the merge conveyance path, The front end of the stored banknote 41 is located a predetermined distance behind the front end of the input banknote 40. Since this predetermined length is shorter than the length of the banknotes in the conveyance direction, the stored banknotes 41 and the input banknotes 40 overlap in part (the part obtained by subtracting the predetermined length from the length in the conveyance direction). (Figure 5B). This way of stacking is 4 bills inserted.
0 is on top, and stored banknotes 41 are on bottom.

In this state, when timer A times up, the rotation of motors 3, 6, 13, and 19 is stopped (n5, n6). When the timer A times up, the rear end of the input banknote 40 has reached the converging conveyance path, and the banknote 40 stops with the rear end placed on the upper surface of the stored banknote 41 (FIG. 5C).

Next, turn on the solenoid 10, and turn on the flapper 11.
Move (n7). This movement of the flapper 11 blocks the input conveyance path to the receiving port 1 side. Subsequently, the motors 13 and 19 are rotated counterclockwise, and the motor 6 is rotated clockwise (n8). By this motor drive, the inserted banknotes 40 are guided to the drum 12 side while being overlapped with the stored banknotes 41, and are wound between the drum 12 and the wrapping tape 15.

When the rear end of the inserted banknote 40 turns off the detector 9 (n9: D in FIG. 5), the timer B held by the CPU 30
(not shown) and solenoid 1.
0 and return the flapper 11 to its original position (n10, n11). The timer B monitors when the trailing edge of the bill is conveyed to the vicinity of the bottom of the flapper 11, and when the timer B times up, the motors 6, 13, 19 are activated.
and end the fishing tag storage operation (n12,
n13: Figure 5E). Timer B corresponds to the second timer of this invention.

The operation shown in FIG. 3 corresponds to the storage control means of the present invention.

FIG. 4 shows the operation when the banknotes stored between the drum and the tape are fed out as a change ticket. When a change ticket request signal is received from the vending machine main body, the motor 6 is reversed counterclockwise, and the motors 13 and 19 are rotated forward clockwise. (n20, n21) By driving these motors, the conveyor belt 7 rotates in the unloading direction, the drum 12 rotates clockwise, and the wrapping tape 15 is rewound and rotates in the direction to be separated from the drum 12. . This rotation causes the drum to
The stored banknotes that have been wound between the tapes are fed out and conveyed in the direction of the banknote discharge port 14 while being placed on the belt 7. At this time, the belt 8 is not rotating. The stored banknotes fed out from between the drum and the tape turn on the detector 9, and then turn on the detector 1.
6 is turned on (n22, 23: F in Figure 5), it is determined that one change bill has been conveyed to the feed roller 17 near the detector 16, and the motors 13, 19 are turned on.
stop (n24). Subsequently, the solenoid 20 is turned on to move the feed roller 17 upward and press the belt 7 against the roller of the belt 8 facing it. Since the position of the feed roller 17 substantially coincides with the position of the detector 16, the belt 7 and the belt 8
The tip of the banknote is held between the two. By the way,
The banknotes conveyed to the vicinity of the detector 16 are sent out to the discharge port 14 side by the pressure of the delivery roller 17. When the detector 16 turns off when the feed roller 17 finishes feeding, the solenoid 20
Turn off (n26, n27). If there is a change bill request signal after the solenoid 20 is turned off, the drum 12 and wrapping tape 15 are similarly rotated clockwise until the tip of the stored bill turns on the detector 16, and then the feeding roller 17 is turned on. Then, one by one, the bills were released. When the ticket discharging is finished (n28), the motors 13 and 19 are reversed counterclockwise, and the motor 6 is rotated forward clockwise (n29). By driving this motor, the stored banknotes that have been carried out to the front of the detector 16 are rewound to a standby position near the flapper 11. When the detector 9 turns off (similar to FIG. 5D), it is determined that the trailing edge of the bill has been conveyed to the standby position, and the timer B is reset (n30, n31). This timer B monitors the trailing edge of the bill for a certain period of time after it passes the detector 9, and
When the time is up, the motors 6, 13, and 19 are stopped and the process ends (n32, n33: same as in FIG. 5E).
The operation shown in FIG. 4 corresponds to the release control means of the present invention.

Through the above process, the stored banknotes are conveyed between the belts 7 and 8 in the direction of the banknote discharge port 14 by the rotation of the drum 12 and the movement of the tape 15. At this time, the belt 7 is also rotating due to the rotation of the motor 6, but since the belt 8 is not in contact with the belt 7, it is not rotating. Because there is no
The banknotes are conveyed exclusively by the action of the drum 12 and tape 15. After that, when the leading edge of the first bill reaches the position of the detector 16, the drum 12
Then, the tape 15 stops, and the belt 7 and the belt 8 are brought into pressure contact with each other while the bill is being held between them by the movement of the feed roller 17. By this,
The first bill further moves in the direction of the discharge port 14. However, the second banknote is not held between the belts 7 and 8, the frictional resistance generated between the second banknote and the third banknote is higher than the frictional resistance between the belt 7, and the drum. Since the tape 12 and the tape 15 are stopped, they do not move in the direction of the discharge port 14, and the first bill is separated from the second bill. In this way, when the fishing tags are released, the fishing tags rewound from the drum can be fed to the delivery roller 17 and the fishing tags can be released one by one. Therefore, the fishing tags can be stored, replenished, and fed out using the fishing tag storage mechanism consisting of the drum 12 and the wrapping tape 15, thereby eliminating the need to prepare a large number of fishing tags in advance. Without,
Moreover, by storing the fishing tags at any time, the occurrence of running out of fishing tags can be greatly reduced, and the operating rate of the vending machine can be improved.

(g) Effects of the Invention As described above, according to the present invention, banknotes can be held by being wound in a stepped manner between the drum circumferential surface and the wrapping tape, so that the held banknotes cannot be released one by one. Not only is this possible, but a large number of tapes can be held between a limited length of wrapped tape. Furthermore, since the transported banknotes can be guided and held between the circumferential surface of the drum and the wrapping tape, even if the change tags are released, the input banknotes can be replenished as change tags on the drum side. , the occurrence of running out of fishing tags can be significantly reduced without having to prepare a large number of fishing tags in advance, and the operating rate of the device can be improved. Moreover, even if a relatively long wrapping tape is used, the bills are stored in the space around the drum, so a large number of fishing bills can be stored in a limited space, and the entire device can be made compact. can.
