Next, the bill processing operation will be described with reference to FIGS. Note that FIG. 2 shows the positions of the sensors and motors for processing the bills, and the sensors and the like are shown in the configuration diagram shown in FIG. 1 for convenience of illustration. First, the processing at the time of inserting the first bill will be sequentially described. When a bill is inserted into the bill insertion slot 11, the BV entrance sensor detects the bill insertion, and the detection signal V1 shown in FIG. 4 (A) is supplied to the control unit 8. At this time, if the banknotes of the customer are retained in the storage section 5, the storage motor M3 is driven (high level H) to store the banknotes in the cashbox section 6 as shown in FIG. 4 (I). To do. Then, the pusher fixed position confirmation sensor PH6 operates from OFF (low level L) to ON (high level H) as shown in FIG. ), The storage motor M3 is controlled to be turned off. During this period, the entrance conveyance motor M1 is driven as indicated by the high level H in FIG. 4 (B) to convey the inserted bill in the direction of arrow A. The transport speed is set to 700 mm / s, for example.

When the bill is conveyed to the entrance conveyance section 3, it is detected by the entrance holding sensor PH1 as shown in FIG. 4C, and a high level detection signal V2 is supplied to the control section 6. Then, after delaying for a predetermined time, for example, 100 ms, the inlet clamp solenoid SL1 and the inlet stopper solenoid SL2 are driven as shown by the high level H as shown in FIGS. 4 (D) and 4 (E). At the same time, the main transport motor M2 is driven as shown in FIG. 4 (F). As a result, the banknote is conveyed from the entrance conveyance section 3 toward the primary holding section 4 as indicated by arrow A while being sandwiched between the belts 13 and 14.

When the banknotes are conveyed to the installation position of the turn sensor PH2 while being sandwiched between the belts 14 and 15 which form the primary storage unit 4, as shown by a high level H in FIG. 4 (G). The bill is detected, and the detection signal V3 is supplied to the control unit 8. Then, the controller 8 controls the inlet clamp solenoid SL1, the inlet stopper solenoid SL2, and the inlet transport motor M1 to be turned off. The bills are continuously conveyed by the main conveyance motor M2, and when they are conveyed to the installation position of the primary hold sensor PH3, they are detected as shown by the high level H in FIG. 4 (H). The detection signal V4 is supplied to the control unit 8, and the control unit 8 controls the main carry motor M2 to be turned off, for example, about 50 ms after the detection, as shown in FIG. 4 (E). However, when the next banknote is continuously inserted and detected by the entrance hold sensor PH1, the transport speed is switched to, for example, 350 ms and the standby state is set.

Next, with reference to FIG. 5, a processing operation at the time of inserting the second and subsequent bills will be described. When a bill is inserted into the bill insertion slot 11, it is detected by the entrance sensor of the BV as shown in FIG. 5 (A), and the entrance conveyance motor M1 is driven as shown in FIG. 5 (B). As a result, the bill is transported to the entrance transport unit 3 at a transport speed of about 700 mm / s. However, if the primary holding of the bill inserted earlier is not completed and the installation position of the turn sensor PH2 has not been reached, the entrance conveyance motor M1 is not turned off. The operation of driving the motor M1 is not performed. Such control is entirely performed by the control unit 8.

On the other hand, when the first holding of the previously inserted bill is completed and the bill is in the standby state, the main carrying motor M2 is turned on, but the carrying speed is as shown in period T of FIG. 5 (F). Is set to, for example, 350 mm / s. If the primary hold is not completed, the carrying speed of the main carry motor M2 is controlled to be switched from 700 mm / s to 350 mm / s as soon as the primary hold is completed. The inserted bill is detected as shown in Fig. 5 (C) when it is conveyed to the installation position of the entrance hold sensor PH1, and after t time (for example, 50 ms) from the time of detection, it is detected in Fig. 5 (D). As shown in FIG. 5 (E), the inlet clamp solenoid SL1 and the inlet stopper solenoid SL2 are turned on. Next, after the inserted bill is conveyed based on the designated pulse number (however, shown by time width t1 in FIG. 4 (C)), the conveyance speed of the entrance conveyance motor M1 which was 700 mm / s is shown in FIG. 5 (B). The period indicated by the width T1 is switched to 350 mm / s. At the same time, as shown in FIG. 5 (I), the holding stopper solenoid SL4 is driven so that the first holding section 4 conveys the first inserted bill that was in the standby state.

In this state, the inserted banknotes and the remaining banknotes (previously inserted banknotes) are conveyed for the designated pulse. When the overlapping amount reaches about 3 cm from the leading edge of the banknotes, Referring to FIG. 5, after the time widths T and T1 have passed, the rotation speeds of the entrance transport motor M1 and the main transport motor M2 are switched again to set the transport speed to 700 mm 2 / s. Then, when the bill is conveyed and is conveyed to the installation position of the turn sensor PH2, it is detected as shown in a high level in FIG. 5 (G), and this detection causes the entrance conveyance motor M1, The clamp solenoid SL1 and the stopper solenoid SL2 are controlled to be off. However, as shown in FIG. 5 (F), the main transport motor M 2 continues to be driven, so that the bills are transported toward the installation position of the primary hold sensor PH3.

When the bill is detected by the primary hold sensor PH3, the detection output is turned on as shown at the time point Tb, and after about 50 ms, the main conveyance motor M2 is controlled to be turned off as shown at the time point Tc. However, when the next inserted banknote has reached the installation position of the entrance hold sensor PH1, the conveyance speed is switched to 350 mm / s and it is made to stand by.

Next, a bill processing operation when a transaction is completed will be described. The transaction is completed when the person who purchases the ticket presses the amount button (not shown). When it is determined that the amount of the inserted banknotes and the amount button match each other and the transaction is successful, the storage solenoid SL5 is turned on as shown in FIG. 6 (D), and the main transfer is performed as shown in FIG. 6 (A). The motor M2 is also controlled to be on. When the banknotes in the standby state are transported to the installation position of the storage stopper solenoid SL4 in the primary storage section 4, SL4 is turned on as shown in FIG. 6 (C) and retracts from the transport path to store the banknotes in the storage section 5 Transport to. The transport speed at this time is 700 mm / s. Then, when the bill is conveyed to the installation position of the storage holding sensor PH4, it is turned on as shown in FIG. 6 (E), and after about 50 ms, it is held as shown in FIG. 6 (C) and FIG. 6 (D). The stay stopper solenoid SL4 and the storage solenoid SL5 are controlled to be off.

Next, a bill processing operation when a transaction is unsuccessful will be described. A person who purchases a ticket presses a cancel button (not shown) to fail the transaction. In this case, as shown at time td in FIG. 7, the main transport motor M2, the return drive clutch SL6, the reject solenoid SL3, and the hold are further held. Each of the stopper solenoids SL4 is controlled to be turned on, and the bill is conveyed to the return unit 6. At this time, the transport speed is controlled to 700 mm / s. When the bills are conveyed to the setting position of the return hold sensor PH5, they are turned on as shown in FIG. 7 (G), and after the return bills are conveyed for a predetermined pulse from this time te, the time width is shown as follows. After the lapse of the time width t2 shown in FIG. 7 (G), the explanation will be further given with reference to another drawing. As shown in FIG. 3, the leading end of the banknote X is about the end of the withdrawal opening 25 provided in the return section 6. When the length of 70 mm is reached, the return drive clutch SL6, the reject solenoid SL3, the holding stopper SL3, and the main transport motor M2 are controlled to be off as shown at time tf.

Since the returned banknotes are about 70 mm out of the tip of the return section 6, the person who purchases the tickets can take them out by hand, and the ticket sale ends when the taking out is done. However, it is often forgotten, and in such a case, the following controls are performed to prevent theft.

When there is a banknote that has been forgotten to be taken, a not-yet-taken timer, which is not shown, operates, and after a predetermined time has elapsed, the reject solenoid SL3 is turned on as shown at time tg in FIG. As a result, as shown in FIG. 3, a transport path Y for the paper sheet X is formed between the primary holding section 4 and the returning section 6. Then, at the time point th when a predetermined time has elapsed, the main transport motor M2 is rotated in the reverse direction as shown in FIG. 8 (A), and at the same time, the return drive clutch SL6 is driven. Therefore, the belts 16 and 17 that form the primary holding unit 4 and the belts 23 and 24 that form the return unit 6 all run in the opposite direction when the banknotes are discharged, that is, when they are conveyed to the return unit 6. .. Most of the paper money X whose tip is viewed from the return section 6 is sandwiched between the belts 23 and 24, so that the belts 23 and 24 travel in the opposite directions so that they are drawn into the return section 6. Become. The transport speed is set to about 700 mm / s.

The drawn-in banknote X is first conveyed in the upward ascending direction in FIG. 3 by the traveling of the belts 23 and 24, and then traveling to the right on the conveying path Y, and is conveyed into the primary holding section 4. become. A turn sensor PH2 is installed in the primary holding unit 4, and the bill X is applied to the turn sensor PH2 and operates in the ON state as shown in FIG. 8B until it passes. Then, after passing, it is turned off, and as shown at time ti, the main transport motor M2, the return drive clutch SL6, and the reject solenoid SL3 are turned off.

In this state, the taken-in bill X is held in the primary holding unit 4. Then, at time tj when a predetermined time has elapsed, the main transport motor M2 is turned on, that is, the forward rotation is controlled, and the holding stopper solenoid SL4 and the storage solenoid SL5 are turned on. As a result, the banknote X is conveyed from the upper side to the lower side of the primary storage unit 4 while being sandwiched between the belts 16 and 17, and further vertically downward by the belts 21 and 22 forming the storage unit 5. Be transported.

When the banknote X reaches the installation position of the storage holding sensor PH4, it is turned on as shown in FIG. 8 (F), and at the time tl about 50 ms after this time tk, the main conveyance motor M 2 and the holding stopper. The solenoid SL4 and the storage solenoid SL5 are controlled to be off. When the conveyance of the bill X is stopped and the holding in the storage section 5 is completed, the pusher fixed position confirmation sensor PH6 operates to drive the storage motor M3 from OFF to ON and then OFF. As a result, the pusher 31 moves in the direction of the arrow B shown in FIG. 1 to push the bill X into the safe 7, and then returns to the original position to end the storage of the bill X.

As described above, according to the present embodiment, if the return banknote X is forgotten, the banknote is reversely conveyed into the device and taken in after a lapse of a predetermined time, so that the theft accident can be prevented. In addition, when a person who has forgotten to take a request makes a request, the person in charge can return it because the returned banknotes are stored, and it is possible to prevent problems with the return.

The following effects can be obtained by applying an electromagnetic clutch to the return drive clutch SL6. That is, the belts 15 to 17 that form the primary holding unit 4 and the belts 23 and 24 that form the return unit 6 are both driven by the main transport motor M2. Therefore, if the main transport motor M2 is rotated in the forward and reverse directions, the returned banknote X can be transported to the return section 6 and, if it has been forgotten, to be transported back into the apparatus.

However, since the rotating device such as the main transport motor M2 has inertia, it continues to rotate even if it is turned off. Then, if it is controlled to be turned off and is made to rotate in the reverse direction before the rotation is stopped, operation delay, impact, etc. occur, which is not preferable. Therefore, in this embodiment, an electromagnetic clutch is applied to rotate the main conveyance motor in a predetermined direction, and the connection of the load belt is changed to change the conveyance direction of the belt. According to this configuration, the inconvenience can be prevented and the returned bills can be taken in smoothly.

A photo sensor is applied to each of the sensors PH1 to PH5 and the secondary hold sensor PH9 in the embodiment, and a photo interrupter is provided to the pusher fixed position sensor PH6, the full detection sensor PH7, and the full advance detection sensor PH8. Has been applied. Further, the counting of the bill conveyance time is performed by an electromagnetic counter, and DC solenoids are applied to SL1 to SL5. Further, a stepping motor is applied to the motors M1 and M2, and a DC motor is applied to the motor M3.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and various modifications can be made. For example, the sensor for detecting the position of the bill is not limited to the photo sensor, and can be replaced with a touch sensor. The application of the present invention is not limited to ticket vending machines, but can be widely applied to vending machines for various products.
