Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control system for a banknote identification device, and in particular, to prevent a banknote that has been counted and determined to be a genuine banknote from being returned to a customer side together with a subsequently inserted banknote. The genuine banknotes that have already been counted are released from the subsequently inserted banknotes and then stored.

A typical banknote identification device includes an escrow mechanism that temporarily holds banknotes determined to be genuine banknotes in preparation for return at the customer's request. In addition, banknotes determined to be counterfeit banknotes are returned to the customer, but regardless of the return operation, in such an identification device, sometimes genuine banknotes that have been inserted and counted first are inserted subsequently. It happens that people are taken back for banknotes that have been stolen. Such problems tend to occur especially when the storage box for storing genuine banknotes is full, and the rear end of the inserted banknote, which was supposed to be fed into the storage box from the temporary holding position, may end up on the conveyance path. If the banknote remains in the terminal section of the banknote, when the next banknote is returned, the leading edge of this banknote overlaps with the rear end of the banknote mentioned above, and the banknote is brought back to the counted banknote along with the banknote to be returned. .

Therefore, by using the banknote validator proposed by the present applicant in Japanese Patent Application No. 13003, it is possible to prevent such accidents from occurring.

In other words, this banknote validating machine is configured to identify the length and thickness of the banknote even during the banknote return operation. Detect.

When this abnormality is detected, the banknote return operation is immediately stopped at that position, the banknote is held as it is, and an abnormality signal is output to the outside.

In this case, if a counted genuine banknote is about to be taken back by the return operation of the next inserted banknote, the return operation is immediately stopped, so that the counted genuine banknote is returned together with the counterfeit banknote. There is no chance of being sent back.

However, if the return operation is stopped by such a banknote validating machine, it is difficult to determine whether all the banknotes, including the one that was being taken back, were inserted by the same customer, or whether the return operation was caused. Since it is not possible to distinguish whether the lost banknotes and the banknotes that were about to be taken back were brought in by another customer, it is easy to cause problems with customers.

Further, in this device, the operation of the bill receiving station is stopped as an abnormal state until these two bills are removed, which affects the operating rate of the entire system equipment equipped with such a bill validator.

The purpose of the present invention is to solve such problems and to separate only the banknotes that need to be returned from the counted true banknotes that are being taken back and return them without K, thereby reducing the relationship between customers and customers. An object of the present invention is to provide a control method for a banknote identification device that reduces the causes of disputes and does not affect the operating rate of system equipment.

That is, in the present invention, the authenticity of the banknotes being conveyed is determined in the recognition device, and the genuine banknotes identified as genuine are conveyed to a temporary holding position behind the recognition device and stopped, and then collected. At the bank, genuine banknotes that are transported in the opposite direction through the identification device are transported in the opposite direction through the identification device and returned in response to the signal. The genuine banknotes identified by the identification device as being in the papermaking section during transport in the reverse direction are once transported from the temporary holding position to the rear by a predetermined distance, and then transported in the reverse direction again. The present invention is characterized in that the banknotes are then identified again by the identification device, and if the genuine banknotes conveyed in the opposite direction are identified by the identification device as being in a predetermined turning unit, an abnormality signal is issued and return is stopped. That is.

The following is a detailed explanation of the present invention with reference to the drawings. In FIG. (not shown) to the conveyance path q. Figure 1 (color) shows various detection sensors arranged on the conveyance path FK, where 5 and 6 are position detection sensors installed symmetrically near the entrance of the conveyance path I, 7 is a thickness detection sensor, and 1 is a pattern detection sensor, and 9 and 10 are position detection sensors.

Here, the three banknotes guided to the conveyance path q are distinguished by the position detection sensor j, ≦ and 9, the thickness detection sensor 7, the pattern detection sensor 1, etc., and the rear end of the banknote 3 is It is temporarily held at the position immediately after passing the position. If the verification result is "true," the banknotes held in this position will be activated by an opening signal that instructs them to collect the money.
As the conveying means continues to rotate in the normal direction, the bill is guided to the bill storage box, allowed to fall freely and stored, and is returned to the insertion port if the park opening signal instructs return.

Further, if the discrimination result is "false", the conveying means is immediately reversed and the counterfeit bills are automatically returned to the insertion slot.
, q and lθ, the thickness detection sensor 7, etc., again,
It is configured so that length, thickness, etc. can be detected.

Therefore, during this return operation, as shown in FIG. 2 (1), the already counted genuine banknotes 3A are brought back toward the insertion slot 2 by the newly inserted returned banknotes 3B in the holding position. If an attempt is made to do so, the abnormal operation of the lint will be detected as an abnormality in length or thickness by the above-mentioned sensors j to 7.9 and IO.

Upon detection of this abnormal operation, the reverse rotation of the conveying means (refer to FIG. 2 (B)), which is the return operation, is immediately stopped, and the return operation is changed to normal rotation, so that the rear end of the return banknote 3B is a predetermined distance from the position detection top/suction 9. When it reaches a position that has passed by L, the conveying means is stopped again (see FIG. 1 (C)).

In setting this length L, it is assumed in advance that the rear end of the genuine banknote 3 mm will be released from the end portion of the conveyance path. Therefore, as shown in FIG. 2 ((3), genuine banknotes 3
Only the banknotes A are separated from the return banknotes 3B and stored in the storage box //, and the return banknotes 3B remain held by the transport means on the transport path. Therefore.

From this state, the sensor is switched again to the return operation, and the sensor! ~7.9 and 10 etc. detect the presence or absence of an abnormal operation, and if the genuine banknote 3M has already been cut and separated from the return banknote 3B and stored, only the return banknote 3B is returned as is.

However, if an abnormal operation is still detected after this repeated return operation, the return operation is stopped again in the state shown in 2m(B)K and the position shown in FIG. 1(0) is reached. The feeding operation is performed at intervals, and the number of these abnormal operations is counted by a counter. Further, the counter is provided with a preset type circuit, and when the number of abnormal operations reaches a predetermined number of times set in advance, an abnormal signal is outputted to the outside for the first time. After outputting this abnormal signal, the normal operation of storing and returning SO in the identification device/Ic is stopped until the returned banknote 3B is removed from the conveyor SD (this is set to indicate an alarm path). Here, J7 detects one position during normal rotation and reverse rotation of the conveyance means, that is, during normal banknote discrimination and when returning banknotes, including detection of abnormal operation. This is an identification circuit that identifies the banknote 3 based on outputs from the thickness detection sensor 7, pattern detection sensor, and the like.

Reference numeral 1 denotes a reference clock generation circuit that generates clock pulses proportional to the number of rotations of a transport motor (not shown), and supplies the clock pulses to the identification circuit X and the abnormal return control circuit U. 2? is a forward/reverse control circuit that rotates the transport motor forward or reverse in response to requests from other circuits.

Now, when the banknote 3 being conveyed by the forward rotation of the conveying means is judged to be a genuine banknote by the identification circuit, and furthermore, when there is a collection signal in the external signal processing circuit 2, The forward rotation control circuit B is commanded to perform forward rotation, and the external signal processing circuit 7 receives a refund signal! If so, the control circuit n is commanded to reverse the rotation. Furthermore, if it is determined that the bill is a counterfeit bill, the transport means is reversed by the forward/reverse control circuit n until the time t.At this time, if an abnormal operation detection signal is output from the identification circuit X, the abnormal return control circuit n is activated. make it work.

In this way, the abnormal return control circuit 22Fi and the forward/reverse control circuit n are commanded to switch from reverse to forward rotation, and as soon as the banknote 3 is detected by the identification circuit as having passed through the position detection unit 9, B starts counting the pulses from the clock generation circuit I. Until the five banknotes 3 pass the position detection sensor 9 and advance a predetermined distance, the above normal rotation is sent to the control circuit n via the control circuit n. This is a setting circuit provided for continuous operation.In this setting circuit B, the distance is set to a value converted into a reference clock number, and when the count value in the control circuit n reaches the set value, the forward/reverse control circuit nK is set. A command is given to stop normal rotation, and then a command is given to reverse rotation, which is a return operation.

This is a setting circuit that allows the allowable number of repetitions to be set in advance for the occurrence of an abnormal operation during the return operation. Therefore, when the abnormal operation is repeated and reaches a predetermined number of times, an abnormal signal is output to the forward/reverse control circuit 23 and the alarm signal generation circuit 1 via the control circuit n, and the operation of the conveying means is stopped to remove the returned banknotes 3B. At the same time, the alarm signal generating circuit 1 generates an alarm signal.

As explained above, according to the present invention, even when a single banknote is returned, the returned banknotes are classified by FA again by the sensor, and the returned banknotes are detected as an abnormal operation that brings back genuine banknotes that have already been counted. When the determination is made, the return operation is immediately stopped, the transfer device is changed from the reverse rotation operation at the time of return to the forward rotation operation at the time of storage, and both banknotes are moved toward the storage direction by a predetermined distance from the previously stopped position. By sending the banknotes, the genuine banknotes that were about to be taken back are released from the returned banknotes, and then the return operation is started again.
Even after performing these series of return prevention operations, if an abnormal operation is detected in the return operation again, these series of return prevention operations are further repeated, and when the number of repetitions reaches at least 1, the conveying means is completely stopped. Since the system generates an alarm signal when the banknote is returned, it is possible to prevent most of the abnormal operations that bring back genuine banknotes without stopping the function of the identification device, thereby avoiding trouble with customers. A decrease in the operating rate of the entire system including this device can be prevented.

Furthermore, if the abnormal operation continues, the return operation can be stopped, an alarm can be issued, and the outside can be contacted. Furthermore, since such abnormal operations can be prevented, it is possible to prevent mischief by the customer with the intention of intentionally taking the customer back. It is also useful for detecting the full state of the storage box, which is the main cause of such abnormal operation.
