Description

[Detailed Description of the Invention] (a) Field of Industrial Application This invention relates to a forgotten bill collection device that is installed in the bill retrieval section of an automatic cash withdrawal device and that collects once ejected bills (banknotes) again.

(b) Prior Art A banknote dispensing device installed in an automatic teller machine or the like is a device that dispenses banknotes from an internal safe, conveys the banknotes using two sets of upper and lower belt devices, and discharges the banknotes into a tray on a customer service panel. be.

In such banknote handling machines, if a customer forgets to take out the discharged banknotes, if they are left unattended, someone may illegally take them away and cause trouble, so they are collected in the machine. . For this reason, automated teller machines have conventionally been provided with a forgotten bill collection device. Conventional devices for collecting forgotten banknotes are equipped with a shutter that closes the receiving tray, and when a banknote is left behind, the shutter is closed.The conveyor belt is reversed and the banknotes are collected into the device.

(c) Problems to be solved by the invention However, in the method described above, once a device is forgotten, it becomes unusable, resulting in a decrease in operational efficiency. Therefore, this method is mainly adopted, but in conventional banknote processing devices, as shown in Japanese Patent Application Laid-open No. 57-199067, for example, a method is used in which the ejected banknotes are held while being clamped on a conveyor belt so that they can be recovered. was taken. This method had the disadvantage that it was difficult for customers to remove their bills, and they were more likely to forget to take them out. In addition, in this type of system, the bills to be discharged must be discharged all at once, so in order to discharge multiple bills of different types, they must be arranged inside the device and then fed into the discharge conveyance path. This has the drawback that the process becomes extremely complicated and transportation control is extremely difficult.Also, since the materials must be collected all at once, transportation control is difficult and jams are likely to occur.

Furthermore, as shown in Japanese Patent Application Laid-Open No. 59-11489, the banknotes that have been arranged in a row are projected from the deposit/withdrawal slot, and when the banknotes are forgotten, the entire banknotes are taken into the storage chamber, and then the banknotes are removed. It is designed to be taken into the interior one by one. In such a device, forgotten banknotes are first taken into the storage chamber and then taken in one by one, so the taking-in operation is performed in two stages, which slows down the overall processing speed. Furthermore, when discharging banknotes, the banknotes are once aligned before being discharged, which again has the disadvantage of slow processing speed.

The object of this invention is to provide a forgotten bill collecting device that solves the above-mentioned problems by feeding out and collecting bills one by one that have been completely ejected onto a tray.

(d) Means for solving the problem This invention is a device that transports bills while sandwiching them between two sets of upper and lower belt devices, and releases the bills into a receiving tray at the end of the belt. (the pulley at the end of the lower belt device on the tray side), bills are deposited on the top surface, and the collection belt device is provided as a part of the tray that can freely rotate in the direction of paying out and collecting bills. A cam mechanism is provided to move the collection belt device up and down from the tray surface to a position where it abuts the upper pulley, and further includes a bill detector for detecting the presence or absence of bills on the tray, and a fixed time period after discharging a predetermined bill. When the bill detector continues to detect bills even after the period has elapsed, the cam mechanism is driven to bring the collection belt device into contact with the upper pulley, and the two sets of upper and lower belt devices are driven in the collection direction. It is characterized by having a collection means and.

(e) Function In the forgotten tag collecting device of this invention, during normal operation, the collecting belt device is located on the tray surface and forms a part of the tray. When a bill (generally banknote) discharging operation is performed, two sets of upper and lower belt devices (transport belts) are driven in the discharging direction, and a predetermined number of bills of a predetermined type are discharged onto a tray. The tag is released completely onto the tray away from the belt device so that it can be easily removed by the customer.

Here, if the customer forgets to take some or all of the bills for some reason, the bill detector detects this and drives the cam mechanism to move the collection belt device upward. With this movement, the forgotten tag is placed on the collection belt, and the collection belt device comes into contact with the upper pulley. In this state, the conveyor belt is driven in the collection direction. Due to this drive, the collection belt device is also driven in the collection direction, and the forgotten tag is conveyed to between the upper pulley and the collection belt device. Thereafter, the forgotten tag is conveyed by a drive belt to a collection position (such as a collection box provided halfway from the release route) and collected. When a plurality of bills are simultaneously conveyed to between the upper pulley and the collecting belt device, the upper bill is collected first by the conveying force of the upper pulley. At this time, the lower tag is stopped by the frictional force of the collection belt device. This allows the sheets to be fed out and collected one by one. Further, even if bills of different sizes are released, they can all be collected one after another because they are conveyed on the collection belt device.

(f) Embodiment FIG. 1A is a side view of a left-behind tag collecting device which is an embodiment of this invention, and FIG. 1B is a plan view of the same. In the figure, 1 and 2 are an upper belt and a lower belt for conveying bills. The tag 3 is held between these two upper and lower belts, and is conveyed in the direction of arrow A when released, and conveyed in the direction of arrow B when collected.
The upper belt 1 is stretched between a roller pulley 5 (upper pulley) disposed on the tray 4 side and a pulley (not shown) disposed on the bill accumulation side. The lower belt 2 is stretched between a flat pulley 6 arranged on the tray 4 side and a pulley (not shown) arranged on the banknote accumulation side. The roller pulley 5 is located slightly closer to the tray 4 than the flat pulley 6, so that the upper belt 1 can easily come into contact with a recovery pulley, which will be described later.
The length from the center of the roller pulley 5 to the front end of the tray 4 is set approximately equal to the length of the longest bill that can be handled by the automatic teller machine. A bill detector 7 consisting of an LED 7a and a phototransistor 7b is arranged above and below substantially in the center of the tray 4.

A recovery pulley 8 is disposed below the roller pulley 5 and is movable up and down, facing the pulley 5.
Further, a pulley 9 is rotatably supported on a shaft 18 on the front end side of the receiving tray 4 relative to the recovery pulley 8. A collection belt 10 is hung between the collection pulley 8 and the pulley 9. The collection pulley 8, pulley 9, and collection belt 10 correspond to the collection belt device of this invention. An end portion of a recovery arm 12 that is swingable about a pin 11 is attached to the recovery pulley 8 by a pin 13. The collection arm 12 has an L-shaped cross section, and the cam surface of the collection cam 14 is in contact with the horizontal piece 12a. The recovery arm 12 is further urged upward at all times by a recovery spring 15. The recovery cam 14 and the recovery spring 15 constitute a cam mechanism, and when the recovery cam 14 rotates in the direction of arrow C or D from the solid line position in the figure, the elastic force of the recovery spring 15 causes the recovery arm 12 to move as shown in the figure. Swing upward as shown by the two-dot chain line. That is,
The cam mechanism can be oscillated by a length that causes the collection belt 10 to come into contact with the roller pulley 5. The rotation shaft 14a of the collection cam 14 is connected to a drive shaft to which rotational force is applied from a motor via a forward and reverse clutch mechanism (not shown). As will be described later, if all the bills released into the tray 4 are not taken out within a certain period of time, the forward/reverse clutch mechanism is turned on in the forward rotation direction, and this collection cam 1
4 is rotated by 90 degrees in the direction of arrow C. At this time, the collection arm 12 swings from the solid line position in the figure to the position shown by the two-dot chain line, and the collection belt 10 moves to the roller pulley 5.
come into contact with. It should be noted that a discharge number detector 17 consisting of an LED 17a and a phototransistor 17b arranged behind the roller pulley 5 detects the leading and trailing ends of the discharged bills. Further, 16 is a shutter.

Next, the operation of the recovery device will be explained with reference to FIG. FIG. 2 is a flowchart showing the recovery operation of the recovery device.

When the automatic teller machine enters an operation mode for discharging a predetermined number of bills, the belts 1 and 2 are driven in the bill discharging direction at step n1 (hereinafter, step ni is simply referred to as ni). As a result, the bill is conveyed in the direction of arrow A while being held between the belts 1 and 2, and is discharged onto the receiving tray 4 after being conveyed to the position of the flat pulley 6. Once all cards have been released, the game progresses from n2 to n3. The number of ejected tags is counted by counting the output of a ejected number detector 17 disposed on the tray side of the flat pulley 6. At n3, a timer provided in the control section is activated. After the timer is activated, when the timer expires after a certain period of time has elapsed, it is determined whether there are any remaining bills in the tray 4 based on n4→n5 and the output of the advanced bill detector 7. If not, it will end. If there are any remaining bills, the collection cam 14 is rotated 90 degrees in the C direction at n6. As a result, the collection arm 12 begins to swing counterclockwise, and the collection belt 10 also moves upward accordingly. At this time, since there is a remaining bill on the collection belt 10, the roller pulley 5 and the collection belt 1
If the number is 0, the remaining bills will be pinched. In this state, if belts 1 and 2 are driven in the bill collection direction at n7, the bills in contact with roller pulley 5 will be conveyed in the opposite direction to the discharge direction, and will be held between belts 1 and 2 in the direction B. will be collected. When the rear end of the first remaining bill passes the position of the roller pulley 5, the second remaining bill is subsequently collected by the rotation of the roller pulley 5. When the remaining bills are collected one by one in this way, the collection belt 10
Since the tag exists between the roller pulley 5 and the collection belt 10, no rotational force is applied from the roller pulley 5. Therefore, even if a plurality of remaining bills are sandwiched between the roller pulley 5 and the collection belt 10, they are collected sequentially starting from the top. When all the remaining bills sandwiched between the roller pulley 5 and the collection belt 10 are collected, the collection belt 10 comes into contact with the roller pulley 5. Then, the collection belt 10 is driven in the direction of arrow E. At this time, if there are any remaining bills in the tray 4, the bills are carried to the roller pulley 5 side by the drive of the collection belt 10. When the tip of the tag is sandwiched between the roller pulley 5 and the collection belt 10, the drive of the collection belt 10 is stopped and the tag is collected again in the opposite direction to the release direction by the rotational force of the roller pulley 5 in the same manner as above. To go. When all the remaining bills on the tray 4 are collected in this way, the collection cam 14 is reversed 90 degrees in the D direction at n9, and the collection arm 12 is moved as shown in FIG. 1A.
Return the recovery pulley 8 and recovery belt 10 to the positions shown by the solid lines. When all the remaining bills to be collected that have been conveyed in the B direction by the belts 1 and 2 have been collected (n10), the belts 1 and 2 are stopped and the process ends (n11).

When collecting the bills released into the tray 4 by the above operation, the bills can be collected using the release path. Note that in the above steps, n5 to n11 correspond to the collection means of this invention.

(g) Effects of the invention As described above, the forgotten tag collecting device of this invention has the advantage that the tags to be discharged can be discharged completely away from the conveyor belt (upper and lower belt device), making it easier for customers to receive them. There is. Additionally, when there are remaining bills to be collected in the tray, the remaining bills are collected one by one, which has the advantage of preventing jams and facilitating transport control. .

Furthermore, when storing the remaining bills, the system collects the remaining bills one by one directly from the tray, compared to a device that performs two-step transfer control, where the bills are taken into the storage chamber all at once and then taken inside one by one. This has the advantage that bills left behind can be retrieved quickly.
