[Industrial applications]

 The present invention relates to a banknote transport mechanism which is used, for example, in a banknote exchange machine, a banknote sent through a first transport path is identified by a classifier, and the identified banknote is transported through a second transport path.

[0002]

[Prior art]

 FIG. 2 shows a banknote transport mechanism portion related to the present invention in a conventional banknote changer. When a banknote 13 is inserted into the banknote slot 12 of the money changer 11, the banknote 13 is detected by the entrance sensor 14, and the sensor output is supplied to the control unit 15, which drives the first conveyance path 16. Then, the banknote 13 is conveyed to the discriminator 17. The 1st conveyance path 16 is comprised by the belt conveyance system which conveys the banknote 13 by pinching the banknote 13 between the belts 17 and 18, and driving the belts 17 and 18 by rotation of the motor 19, for example.

When the banknote 13 comes out of the first transport path 16, the banknote 13 is detected by the exit sensor 21, and the output of the exit sensor 21 is supplied to the control section 15. The control section 15 conveys the banknote 23 of the discriminator 17. Is driven to send the bill to the second transport path 24. When the bill 13 is sent to the discriminator 17, the bill is detected by the entrance sensor 22 and the detection output is sent to the controller 15. In this example, the conveying means 23 is also composed of belts 25 and 26 and a motor 27. While the bills are being sent by the transport means 23, the discrimination means 28 discriminates whether the bills are true or false. The identification result is transmitted to the control unit 15.

When the discrimination result is true, the conveyance by the conveying means 23 is continued, and the bills for which the discrimination has been completed exit the discriminator 17 and are sent to the second conveyance path 24. This is detected by the exit sensor 31 of the discriminator 17, and the control unit 15 drives the second transport path 24. Further, it is detected by the entrance sensor 32 of the second transport path 24. The second transport path 24 is also composed of belts 33 and 34 and a motor 35 in this example, and transports banknotes. The banknotes transported by the second transport path 24 are supplied to the safe 36 and stored in the safe 36.

When it is detected from the output of the outlet sensor 21 that the banknote has passed through the first transport path 16, the control unit 15 stops driving the first transport path 16. When it is detected from the output of the exit sensor 31 that the bill has finished exiting the discriminator 17, the control unit 15 stops the driving of the conveying means 23. Similarly, when it is detected from the output of the exit sensor 37 of the second transport path 24 that the bill has passed through the second transport path 24, the control unit 15 stops the driving of the second transport path 24.

When the identifying unit 28 of the identifier 17 identifies false, the control unit 15 drives the conveying unit 23 in the reverse direction, that is, causes the motor 27 to rotate in the reverse direction so that the banknote is conveyed in the first conveying path 16 side. . When the entrance sensor 22 detects that the back-fed banknotes are supplied to the first transport path 16, the control unit 15 drives the first transport path 16 in the reverse direction, that is, drives the motor 19 in the reverse rotation direction to perform the reverse transportation. The bills are sent out from the bill insertion slot 12.

In this case, when it is detected from the output of the entrance sensor 22 that the back-fed bills have been returned from the discriminator 17, the control unit 15 stops the driving of the conveying means 23, and further, the entrance sensor 14 When it is detected from the output that the back-fed banknote has been returned from the first transport path 16 to the insertion port 12 side, the control unit 15 stops the driving of the first transport path 16.

[0008]

[Problems to be solved by the device]

 In the past, the conveyance speed of each banknote in the 1st conveyance path 16, the conveyance means 23, and the 2nd conveyance path 24 was made equal. In such a configuration, when the banknotes are delivered from the first transport path 16 to the transport means 23 and at the time of delivery from the transport means 23 to the second transport path 24, if the timing does not go well, the bills are respectively transferred. A slack or a fold may occur, causing a jam of bills.

When such a banknote jam occurs, the entire banknote transport mechanism stops, making it impossible to exchange money. Also, in order to remove the jammed banknote, it is necessary to remove the outer cover of the money changer. It took a relatively long time to remove the jammed bills.

[0010]

[Means for Solving the Problems]

 According to this invention, the transport speed of the transport means of the discriminator is faster than the transport speed of the first transport path, and the transport speed of the second transport path is further faster than the transport speed of the transport means.

【Example】

The mechanical structure of the present invention is the same as the conventional one, for example, the structure shown in FIG. 2, and an embodiment in which the present invention is applied to the structure of FIG. 2 will be described below. As shown in FIG. 1A, when the bill 13 is inserted into the insertion slot 12 and the bill is detected by the entrance sensor 14, the motor 19 is normally rotated at the speed V _{1 as} indicated by the line 41 to convey the bill 13. When the bill 13 reaches the exit sensor 21, the motor 27 of the discriminator 17 is positively rotated at a speed V ₂ faster than the velocity V _{1 as} indicated by the line 42, and the bill 13 sent to the discriminator 17 is It is transported faster than the transport speed of the first transport path 16. Therefore, when the banknote 13 is transferred from the first transport path 16 to the discriminator 17, the banknote 13 is pulled from the discriminator 17 side, and there is no possibility that the banknote 13 will be sagged or bent. When the bill detection output of the outlet sensor 21 is lost, the rotation of the motor 19 is stopped.

After the banknote 13 is detected by the exit sensor 31 of the discriminator 17 after the discrimination result in the discriminator 17 is determined to be normal, the motor 35 of the second transport path 24 indicates the line 43. Then, the bill 13 that has been forwardly rotated at a speed V ₃ faster than V _{2 and} has exited the discriminator 17 is transferred to the second transport path 24. At this time, the second transport path 24 is billed by the discriminator 17. The banknote 13 is pulled, and the banknote 13 is not slackened or bent.

When the bill detection output from the outlet sensor 31 becomes zero, the motor 27 is stopped. When the banknote 13 is fed into the cashbox 36 by the second transport path 24, the banknote detection output of the exit sensor 37 becomes zero, and the motor 35 is stopped. By the way, as indicated by a line 42 in FIG. 1B, the normal rotation speed V of the motor 27 is set within the discriminator 17.₂If it is determined that the identification result is abnormal while the banknote 13 is being sent, the motor 27 is rotated in the reverse direction as indicated by the line 44, and -V₂The bill 13 is returned to the first transport path 16 side by being rotated at the speed of. When the entrance sensor 22 of the discriminator 17 detects the returned paper 13, the motor 19 of the first transport path 16 indicates -V as indicated by a line 45. ₂ Faster speed-V₃It is rotated by, that is, it is reversed. Therefore, the returned banknote 13 is pulled from the discriminator 17 by the first transport path 16, and there is no possibility that the banknote 13 will be sagged or bent by this transfer.

When a bill cannot be detected by the entrance sensor 22, the motor 27 is stopped. Further, when there is no detection output of the bill from the entrance sensor 14, the rotation of the motor 19 is stopped. At this time, the banknote 13 is completely returned to the slot 12. The difference between the rotational speeds V ₁ and V ₂ and the difference between V ₂ and V ₃ are preferably about 5 to 10%. This invention can be applied not only to a currency exchange machine, but also to a banknote transport mechanism that guides the inserted banknotes in other vending machines, fare payment machines, etc. to the discriminator and stores the banknotes judged to be good in the storage section.

[0015]

[Effect of device]

 As described above, according to the present invention, since the banknote transport speed on the delivery side is increased, there is no possibility that the banknote will be slacked or bent at the delivery part, and therefore the banknote jam will occur at the delivery part. Since the paper jams at the delivery part were the most frequent, the risk that the banknote transport mechanism would be in a stopped state was extremely small, and the number of operations to open the inside to clear the jams was also very small. Become.
