BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bill dispensing device incorporated in a money changing machine, a vending machine for high-priced goods, a cash automatic depositing and dispensing machine, etc. When a conveyance error such as a skew or double feed occurs in a paper sheet ejection device that has a batch reject mechanism that collectively rejects the banknotes that have already accumulated in the holding section. The present invention relates to an improvement of a bill dispensing device that is performed again.

[0002]

2. Description of the Related Art A conventional banknote dispensing device of this type includes, for example, a stocker for storing banknotes for change, a transport mechanism for feeding and transporting the banknotes one by one from the stocker at a predetermined speed, and the transport mechanism. It is common to have a counting unit that counts the number of bills to be conveyed and a temporary holding unit that temporarily holds and accumulates the number of bills counted by the counting unit until a predetermined number is reached.

By the way, in such a bill dispensing device, it is difficult to store the bills in a stocker at a predetermined position because the bills are stored in the stocker manually. In addition, when the banknote is old, wrinkles, folding lines, etc. are often formed or corners are folded, so that the skew (when skewing the banknote from the stocker by the transport mechanism ( Frequently, a feeding error such as skew feeding) or double feeding occurs.

When a conveyance abnormality occurs, it becomes difficult to accurately count bills. In this case, the bills or bill bundles (hereinafter referred to as reject bills) in which these troubles occur are prevented in order to prevent claims from the user. It is generally configured such that it is collected in a reject banknote collection unit provided in a part of the above and not paid out to the user. Therefore, when a bill sensor is arranged in the bill conveying path of the bill dispensing device and the length of the conveyed bill is detected by the bill sensor, it is determined that the bill is longer than the prescribed length. Alternatively, it is determined that an abnormal state such as double feeding has occurred.

When the above-described conveyance abnormality occurs, the bill is conveyed as a bill to be rejected to the hour storage unit from the middle of the normal conveyance route to the reject bill collection unit through the bypass route, and Some continue counting the next banknote.

However, since the bypass path for rejected banknotes is provided separately from the normal transportation path, the size of the entire apparatus increases and the drive mechanism of the bypass path, the transportation path switching mechanism, etc. become complicated and expensive. There was a flaw.

On the other hand, without the bypass path, the abnormal conveyance bills are piled up in the temporary storage unit and accumulated on the counted bills, and the abnormal conveyance bills are collectively inserted into the reject bill collection unit together with the bills that have been normally counted. Some do.

However, if a banknote sensor detects a conveyance error after a large number of banknotes have been normally counted and accumulated in the temporary storage section, the normal count of banknotes will be rejected immediately at once, and after the reject, a new stocker will be ejected from the stocker. It is necessary to count the fed-out bills from the first bill and hold the bills in the temporary holding unit. When a batch reject is executed, it takes time to send it out again and the amount of banknotes stored in the stocker is limited. However, there was a defect in that the utilization efficiency of the device was reduced due to the shortened time.

A temporary holding unit 27 for temporarily holding the deposition,
It is provided with a banknote discharge port 29 arranged in the front part of the apparatus main body 3 for paying out the banknotes 5, 5 that have been accumulated and reserved in the temporary storage section 27.

The vertical conveying path 23 is in contact with the rear surface of the feeder roller 17 and has an endless first conveying belt 31, and above the feeder roller 17 is in contact with the first conveying belt 31. The banknotes 5 formed in the contact traveling area with the facing second endless second conveyor belt 33 and fed out by the feeder roller 17.
Is carried toward the horizontal carrying path 25. Further, the light emitting element 35a and the light receiving element 35b of the transmissive type primary sensor 35 (optical sensor), which also serves as the counting means and the abnormality detecting means, are arranged opposite to each other with the vertical transport path 23 interposed therebetween. The number of passing bills 5 is counted by detecting the passing length of the conveyed bills 5, and the conveyance abnormality at the time of feeding the bills 5 is detected.

The horizontal transport path 25 has a third transport belt 34.
The banknote 5 is formed in the contact traveling area with the endless fourth conveyor belt 37 that is in contact with the upper surface of the banknote 5, and the banknote 5 received from the vertical conveyor path 23 is nipped and conveyed toward the temporary holding unit 27. or,
The light emitting element 39a and the light receiving element 39b of the transmissive secondary sensor 39 (optical sensor) as the re-counting means are arranged opposite to each other with the horizontal conveyance path 25 interposed therebetween, so that the secondary sensor 3
9 is configured to re-count the number of conveyed bills 5 according to a processing method described later.

The temporary holding section 27 is provided with a lower rotary transport belt 43 stretched in an endless manner in order to sequentially accumulate the bills 5 transported by the horizontal transport path 25, and faces the upper surface of the lower rotary transport belt 43. And an endlessly stretched upper rotating conveyor belt 4
7, and when the number of banknotes 5 accumulated on the lower rotary transport belt 43 reaches a required number, the vertical rotary transport belts 47 and 43 sandwich the upper and lower surfaces of the banknote bundles 5 and 5, and the vertical rotary transport belt 43, An elevating / lowering mechanism (not shown) for vertically rotating the front end portion of 47 as shown by an arrow is provided.

When the banknotes 5 and 5 are to be paid out from the banknote discharge port 29, the elevating and rotating mechanism has the front end portions of the vertically rotating transport belts 47 and 43 holding the banknotes 5 and 5 sandwiched between the banknote discharge port 29.
The belt is run in the payout direction after it is raised toward. Further, when the banknotes 5 and 5 accumulated on the lower rotary transport belt 43 are reject banknotes, the front end portions of the vertical rotary transport belts 47 and 43 are lowered toward the banknote collection box 9 of the stocker unit 11. The belt is made to run in the dropping direction and dropped from the dropping opening 50 formed in the upper portion of the bill collecting box 9.

The first to fourth conveyor belts 31, 33, 3
Reference numerals 4 and 37 constitute a transport mechanism for the banknote 5, and each belt is a transport motor 5 connected to a pulley around which each belt is wound.
It is rotated by driving 2. Then, the transport motor 52 can switch the transport speed of the banknote 5 between high speed and low speed in response to an operation signal from the control means 54. Here, when the conveyance speed of the banknotes 5 is low, the speed of the banknotes 5 dropped from the horizontal conveyance path 25 to the temporary holding section 27 is broken even if the banknotes 5 collide with the side wall (not shown) of the temporary holding section 27. It is preferable that the rate is such that the deposits are aligned without causing the occurrence of.

As shown in FIG. 2, the control means 54 has a structure in which the primary sensor 35 and the secondary sensor 39 are separately connected to each other.
The secondary sensor processing unit 51 and the secondary sensor processing unit 53, the counting control unit 55 to which the primary sensor processing unit 51 and the secondary sensor processing unit 53 are connected, and the transfer control unit 55 connected to the counting control unit 55. Speed variable controller 57 connected to the controller 52, feeding controller 59 connected to the count controller 55, holding conveyance controller 61 and reject controller 63, respectively.
And.

The primary sensor processing unit 51 performs the counting of the banknotes 5 by the primary sensor 35 as in the case of the conventional banknote sensor processing, and when the detected banknote length is longer than the normal one, the skew is detected. -Or outputs a signal indicating that an abnormal state such as double feeding has occurred to the counting control unit 55. The counting control unit 55 outputs a normal transport signal (normal time) or a abnormal transport signal to the speed variable control unit 57 and the feeding control unit 59 according to the signal output from the primary sensor processing unit 51.

The speed variable controller 57 is a counting controller 5
When a normal transport signal is input from 5, a control signal for increasing the speed of the transport motor 52 is output to the transport motor 52,
When the conveyance abnormality signal is input, a control signal for lowering the speed of the conveyance motor 52 is output to the conveyance motor 52. or,
When the conveyance normal signal is input again after the conveyance abnormality signal is input from the counting control unit 55, the speed of the conveyance motor 52 is returned to the high speed after a predetermined time has elapsed. This is because the abnormal conveyance bills are conveyed at a low speed until they are dropped into the temporary holding unit 27. Thus, during normal operation, the bill 5 can be conveyed at a high speed to increase the processing speed of the entire dispensing device, and at the same time, the bill 5 having a conveyance abnormality can be conveyed at a low speed to be dropped into the temporary holding section 27. Even when the banknotes 5 collide with the inner wall of the temporary holding unit 27, the banknotes 5 can be aligned and accumulated without being bent at the corners of the banknote 5, and the temporary holding unit 27
It is possible to prevent the abnormal conveyance bills 5 from jamming, and it is possible to secure a sufficient time to detect and analyze the abnormal state of the bills 5 before the bills 5 reach the secondary sensor 39. .

Further, the counting control section 55 outputs a control signal for causing the secondary sensor signal processing section 53 to execute the following processing. For example, when the secondary sensor signal processing unit 53 determines that the skew has occurred in the primary sensor signal processing unit 51, the inclinations of the leading edge and the trailing edge of the banknote 5 are the same due to the secondary sensor 39. If the widths of the banknotes detected by the left and right sensors are the same, it is determined that the banknotes are one, and if the primary sensor 35 determines that a double feed has occurred, the banknotes 5, 5 do not overlap the overlapping portion. It is determined that the number of sheets is two from the length relationship with the set, and the number is counted. After the re-counting by the secondary sensor signal processing unit 53 is completed, the speed variable control unit 57 switches the speed of the conveyance motor 52 to a high speed by the signal from the counting control unit 55, and the feed-out control unit 59. The next bill 5 is fed out and the counting by the primary sensor 35 is performed again.

The feed-out control unit 59 is provided in the feeder roller 17
Means for controlling the payout operation of the banknote 5 by
When the normal conveyance signal is input from the counting control unit 55, the bills 5 are sequentially fed out, and when the abnormal conveyance signal is input, the feeding of the next bill 5 is stopped.

When the number of bills 5 counted by the primary sensor signal processing unit 51 reaches a preset number, the holding conveyance control unit 61 is activated by a signal from the counting control unit 55, 5, a vertical rotation conveyor belt 47 that holds 5
By raising the front end of 43 toward the banknote outlet 29 and running the belts 47 and 43 in the payout direction, the banknote bundles 5 and 5 accumulated and stored in the temporary storage unit 27 are collectively collected from the banknote outlet 29. Pay out.

The reject controller 63 includes a primary sensor 35.
If a conveyance abnormality is detected by the secondary sensor 39 and it cannot be considered that the conveyed banknotes 5 are one or two even by the re-counting by the secondary sensor 39, the vertical rotation conveyor belt 47 is output by the output signal from the counting controller 55. , 43 front ends of the stocker 11 toward the banknote collecting box 9 of the stocker 11, and then the belts 47 and 43 are made to travel in the drop direction to be dropped from the drop opening 50 formed at the upper part of the banknote collecting box 9. .

Next, the operation will be described.

In the above structure, a predetermined number of banknotes 5, 5
To pay out
The banknotes 5 and 5 are drawn out one by one by the drawer 17, and are sequentially accumulated at high speed on the lower rotation transfer belt 43 of the temporary holding section 27 through the vertical transfer path 23 and the horizontal transfer path 25.
When the accumulated number of banknotes 5, 5 reaches a predetermined number, the front end portions of the vertically rotating conveyor belts 47, 43 holding the banknotes 5, 5 are raised toward the banknote outlet 29 and the belts 47, 4 are provided.
The banknote bundles 5 and 5 are collectively dispensed by running the banknote 3 in the dispensing direction.

Here, when a skew or double feed occurs in the transported bill 5, the primary sensor 35 detects the abnormal transport.
When the primary sensor 35 detects the conveyance abnormality of the banknote 5, the control unit 54 stops feeding the next banknote 5 and
The banknote 5 is conveyed at a low speed and the secondary sensor 39 causes the banknote 5 to be recounted. The secondary sensor 39 counts as one or two papers, judging from the conveyed state of the banknotes 5 conveyed at a low speed. Since the bill 5 is conveyed at a low speed, the recounting determination can be stabilized.

After that, the abnormal conveyance bills 5 re-counted by the secondary sensor 39 are further conveyed to be accumulated in the temporary holding section 27. At this time, the abnormally conveyed bills 5 are conveyed at a low speed, so that even if the bills 5 collide with the inner wall of the temporary holding unit 27, it is possible to prevent the bills from being folded, and thus prevent the occurrence of a jam in the temporary holding unit 27. can do.

If it is not possible to count and count the abnormal conveyance bills 5 by recounting the secondary sensor 39,
The control means 54 lowers the front end portions of the vertically rotating transport belts 47, 43 toward the banknote collecting box 9 of the stocker 11 and then moves the belts 47, 43 in the dropping direction to form them on the upper part of the banknote collecting box 9. It is made to drop from the drop opening 50.

Subsequently, a new bill 5 is inserted into the feeder 1
7, when the banknotes 5 are conveyed at a high speed when the banknotes 5 are conveyed at a high speed when the banknotes 5 are conveyed at a high speed through the vertical conveyance path 23 and the horizontal conveyance path 25, the primary sensor 35 counts the banknotes 5 and conveys them. Detect an abnormality.

As described above, according to the present invention, when the banknotes 5 are abnormally conveyed, the banknotes 5 are conveyed at a low speed without immediately rejecting the abnormal conveyance banknotes in the temporary holding section 27 and immediately rejecting them. At the same time, the secondary sensor 39 is configured to count the bills 5 as if they were being conveyed. Therefore, even if a conveyance error occurs after a large number of banknotes are normally counted and accumulated and stored in the temporary storage unit, the normal count of banknotes need not be collectively rejected as long as the secondary sensor 39 can perform the deemed count. . Therefore, the frequency of batch rejects can be reduced, the bill replenishment cycle of the stocker can be lengthened, and the utilization efficiency of the device can be improved.

As described above, the present invention is effective for a paper sheet dispenser adopting the batch reject method, and according to the paper sheet dispenser of the present invention having the batch reject mechanism, the bypass path for reject banknotes is provided. Is peculiar to the paper sheet dispensing device provided separately from the normal transport route, that is, the entire device becomes large, and the switching mechanism and the drive mechanism of the bypass route are complicated, resulting in an increase in cost. There is no.

By disposing a mechanism for correcting an abnormal state on the upstream side of the secondary sensor 39 in the conveying direction, it is possible to improve the probability that the secondary sensor 39 can be considered and counted. As such a correction mechanism, for example, a skew
A mechanism to reduce the amount and a mechanism to separate the double feed better are considered.

[0035]

Since the present invention is constructed and operates as described above, it is particularly useful in a system provided with a mechanism for collectively rejecting conveyance abnormal banknotes together with paper sheets stored in a temporary storage section. When the means detects an abnormal conveyance of the paper sheet, the paper sheet replenishment cycle of the stocker can be lengthened without immediately rejecting it collectively, and the utilization efficiency of the apparatus can be improved.
