Abstract

PURPOSE:To prevent the interference between a paper sheet and a gate before and after carrying passage switching by generating a command for minimizing the moving distance of a carrying passage during gate operation in a device in which the carrying designation of a carrying material is distributed and switched by the gate. CONSTITUTION:In a bill paying device, bills 2 set in a cassette 1 are separated one by one and sent to a carrying passage 5 by a feed roller 3 and a pinch roller 4, and in the course, the bill carrying state is detected by a judging part 8. When a superposed carrying is detected, then, the bill is carried out to a reject box 10 by switching a reject gate 9. When a bill B judged abnormal reached a carrying passage decelerating timing 12, deceleration command is given to a carrying motor 6 to reduce the carrying speed to the lowest speed by sluicing. This sluicing is ended when the bill B reaches a gate operating timing 13, and the reject gate 9 is then switched.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transportation control method for transporting paper sheets such as an automatic teller machine and a cash dispenser used at a financial institution at a high speed one by one, and a method of transporting the paper sheets. The present invention relates to a gate switching control device for changing the transfer destination depending on the state.

[0002]

2. Description of the Related Art Conventionally, in an automatic teller machine (ATM) and a cash dispenser used in financial institutions, paper sheets such as banknotes are transported and stored in a safe,
There is a method of taking out bills from a safe and transporting them to an outlet. Generally, since the paper passes through a discriminating device that determines the number of sheets and authenticity during the conveyance, the sheets are conveyed one by one. As a paper sheet handling device for separating and transporting paper sheets one by one as described above, for example, Japanese Patent Laid-Open No. 59-221
There is one disclosed in Japanese Patent No. 784. According to this, the transport path basically transports the paper sheets at a constant speed. In this case, the paper sheets are divided into normal paper sheets and false or soiled paper sheets or the like on the way, and are switched to separate conveyance paths and sent to the storage box. Further, banknotes are switched depending on the type of money and stored in a safe via another transport path. Therefore, the transfer destination is determined by the state of the paper sheet to be transferred, and the transfer destination is switched by the gate provided on the transfer path.

[0003]

However, in the method of always conveying the paper sheets at a constant conveying speed as described above, the paper sheets on the conveying path interfere with the gate at the time of the gate switching operation. In order not to do so, it is necessary to sufficiently widen the intervals of the paper sheets conveyed with respect to the operating time of the gate. That is, when the interval is not sufficient, while one sheet is being switched to another conveying path, the sheet conveyed in the front or the sheet conveyed next is picked up.
There was a concern that it would interfere with the car and become an obstacle. Therefore, in order to convey a paper sheet having a large dimension in the conveying direction while keeping the number of paper sheets conveyed per unit time constant,
It was necessary to perform the gate operation at high speed to reduce the interval required for the gate operation, or to increase the transfer speed to increase the transfer cycle (distance). In any case,
It is necessary to increase the size of the solenoid for operating the motor and the motor for driving the conveying path, which is a factor that conflicts with the goals of downsizing and cost reduction of the device. An object of the present invention is to solve these conventional problems and to convey a large sheet in the conveying direction without increasing the conveying speed and increasing the gate operation time, and also to realize a unit. An object of the present invention is to provide a transportation control method and apparatus capable of increasing the number of transported sheets per hour.

[0004]

In order to achieve the above-mentioned object, the transfer control method of the present invention comprises: In the transport control method of switching the transport destination of the transport object by switching to the transport path of the transport path, the determination unit drives the transport path to reduce the transport speed to a low speed until the timing at which the transport object operates the sorting mechanism The feature is that an instruction is issued to the system, and when the operation timing is reached, the operation instruction is issued to the drive system of the distribution mechanism.
In addition, the (b) determination unit temporarily changes the transport speed of the transported object by the time the operation timing of the sorting mechanism is reached,
Another feature is that after the sorting operation is completed, a command is issued to the drive system of the transport path so as to restore the transport speed to the original speed again. In addition, the (c) determination unit determines the state of the transported object to be transported on the transport path after the transported object is sent from the stacking unit to the transport path by the sending means, and as a result of the determination, the transport destination When changing and transferring to another transport path by the sorting mechanism, while issuing a command to the drive system of the transport path to reduce the transport speed of the transported object to a low speed by the time the operation timing of the sorting mechanism is reached, It is also characterized in that a command is issued to the sending means so that the sending speed of the sending means is also lowered. Furthermore, (d) the determination unit is characterized in that the timing of activating the sorting mechanism is changed by determining a change in the state of the transported object transported on the transportation path, the size of the transported object, or the transportation speed. .. Further, the transfer control device of the present invention is (e) a transfer device having a transfer path for transferring a transfer object and a distribution mechanism for switching a transfer destination of the transfer object to be transferred. A conveyance state detection sensor for detecting the state, a two-sheet detection sensor for detecting that two conveyed articles are being double-fed, a discrimination sensor for discriminating the authenticity of the conveyed articles, and a passage timing of the conveyed articles. The determination means including a passage sensor for detecting, and the detection state of each sensor determine the transport destination of the transport object, and when the transport destination is changed, the transport path deceleration timing and the distribution mechanism operation timing are set. It is characterized in that a conveyance control means is provided for determining whether or not the conveyed object has reached the conveyance path acceleration timing, and issuing an operation command to the conveyance path drive system when the conveyance object is reached.

[0005]

In the present invention, the distance of movement of the paper sheets is increased over the entire conveying path to convey at high speed, but the distance of movement of the conveying path is reduced only during the gate operation.
The interference between the front and rear sheets and the switching gate during the switching of the transport path is eliminated. Therefore, when it becomes necessary to switch the destination of the paper sheet by the gate during the transportation of the paper sheet, the transport path is temporarily decelerated before switching the gate, Reduce the moving distance of the transport path during switching. That is, the paper sheets accumulated in the accumulating unit are sent to the conveying path after being separated one by one by the separating mechanism, but to the gate unit that controls the conveying destination of the paper sheets during the conveyance. When it is conveyed, if it is necessary to switch the conveyance destination of the paper sheet at the gate part at the conveyance path deceleration start point provided in front of the gate, deceleration of the conveyance path is started. , The gate is switched when the transport speed becomes sufficiently low. Of course, when it is not necessary to switch the transport destination of the sheet at the transport path deceleration start point, the transport path is not decelerated and the sheet is transported at the same speed. As a result, it is possible to reduce the distance between the paper sheets required for the gate operation, and even if the conveyance speed is not increased, the paper sheets having a large dimension in the conveyance direction can be conveyed without reducing the number of sheets conveyed per unit time. It becomes possible to do.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a side view of a banknote dispensing device showing an embodiment of the present invention. In FIG. 1, 1 is a cassette, 2 is a banknote, 3 is a feed roller, 4 is a pinch roller, 5 is a transport path, 6 is a transport motor, 7 is a dispensing port stacker, 8 is a determination unit, Reference numeral 9 is a switching gate (reject gate), 10 is a reject box, and 11 is a withdrawal port. In the banknote dispensing device of FIG. 1, the banknotes 2 set in the cassette 1 are separated one by one by the feeder roller 3 and the pinch roller 4, and sent to the transport path 5. Feeder roller 3 is
It is driven by a motor for a feeder roller (not shown), and its rotation speed can be changed. The transport path 5 is driven by the transport motor 6, and its rotation speed can be changed. Therefore, the rotational speeds of the transport motor 6 and the feeder roller motor are normally kept constant, and the rotational speeds are lowered only when the bills are switched by the reject gate 9. The transport path 5 is
A determination unit 8 for detecting the transport state of the banknote is provided between the transport path 5 which is driven by the transport motor 6 and extends from the separation unit provided with the feeder roller 3 to the dispensing port stacker 7. A reject gate 9 is arranged.

The determination unit 8 checks the state of the banknotes conveyed one by one, and when it is determined that the banknotes should not be conveyed to the dispensing port stacker 7 as they are, for example, when double feeding is detected, the banknotes are The delivery destination of is changed from the withdrawal port stacker 7 to the reject box 10. The banknote whose transfer destination is changed to the reject box 10 is rejected at a position where it is transferred from the determination unit 8 to the reject gate 9.
The conveyance direction is switched to the reject box 10 side by the switch 9 and the sheets are stacked in the reject box 10. The reject gate 9 is driven by a solenoid (not shown), and the gate itself can switch the destination of each banknote. The banknotes that are determined to be normal by the determination unit 8 are conveyed to the dispensing port stacker 7 as they are, and then are collectively transferred to the dispensing port 11 in the dispensing port stacker 7 when a predetermined number is stacked. It is designed to be transported.

FIGS. 2, 3 and 4 are explanatory views showing a method of controlling switching of a reject gate showing an embodiment of the present invention. 2, 3, and 4 are side views showing time-series states on the same conveyance path, respectively. FIG. 2 is a state in which banknotes A and B are conveyed on the conveyance path 5, FIG. In No. 3, the reject gate is completely switched, and the banknote B is the gate.
4 shows a state in which the bill C has reached the leading edge, and FIG. 4 shows a state in which the bill C has reached the conveyance path deceleration timing during the switching operation of the bill B. On the transport path, 12 is a transport path deceleration timing point at which deceleration is started, 13 is a gate operation timing location at which a gate switching operation is started, and 16 is a transport path acceleration at which switching operation ends and acceleration is started. A timing portion, 14 indicates a switching operation completion state of the reject gate 9. FIG. 2 shows a state in which the banknotes A and B are being transported on the transport path 5. For both the banknotes A and B, the determination of the transport state is completed by the determination unit 8 and
Is determined to be normal, and is conveyed toward the dispensing port stacker 7,
The bill B is determined to be abnormal, and the carrying direction is about to be changed by the reject gate 9. When the bill B reaches the transport path deceleration timing 12, a deceleration command is issued to the transport motor 6 and the transport speed is reduced to the minimum speed by the slinging. This threading is completed before the bill B reaches the gate operation timing 13. When the bill B reaches the gate operation timing 13, a drive command is issued to the solenoid for driving the reject gate 9, and the reject gate 9 starts moving to the position of the broken line 14.

At this point in time, since the transport path 5 has been decelerated to the minimum speed as described above, the distance traveled by the banknote B becomes small until the reject gate 9 completely moves, and as a result, The position of the gate operation timing 13 can be brought close to the tip of the reject gate 9. Therefore, the preceding banknote A is sufficiently rejected.
Since the reject gate 9 is switched at the time of passing the banknote 9, the reject gate 9 can be switched without interfering with the banknote A even when the interval between the banknote and the banknote B is narrow. In FIG. 3, the reject gate 9 is shown.
Is completely switched, and the bill B has reached the front end of the gate. At this point, it is clear that the bill A has already passed the reject gate 9 completely. Thereafter, the bill B is switched to the reject box 10 side by the reject gate 9 and, at the same time, reaches the transport path acceleration timing 16. When the banknote B reaches the transportation path acceleration timing 16, the transportation motor 6 is issued with an acceleration command by the slinging. In FIG.
By the time the acceleration command is issued to the transport motor 6 and the succeeding bill C reaches the transport path deceleration timing 12, it reaches the normal transport speed completely. As a result, every time the bill reaches the conveyance path deceleration timing 12, it is checked whether or not the conveyance destination of the bill needs to be changed. -It becomes possible to switch the gate 9.

Further, as described above, the reject gate 9
When performing deceleration control of the transport path 5 when switching
At the same time when the deceleration command is issued to the transport motor 6, the deceleration start is also applied to the feeder roller motor that drives the feeder that feeds the bills into the transport path 5. The deceleration speed of the feeder roller motor is set smaller than that of the transport path 5. This makes it possible to maintain the interval between the bills fed into the transport path 5 at a certain level or more while the transport path 5 is decelerating. Further, the feeder roller motor is accelerated in accordance with the transport path 5 and then is terminated at the same time as the acceleration of the transport path 5 is completed. As a result, even if the reject gate 9 is switched for each banknote and the deceleration of the transport path 5 occurs, the banknote interval in the transport path 5 can be always kept constant or more. Note that the normal transportation speed of bills per unit is about 8 sheets / sec. Although the number of banknotes conveyed per unit time is temporarily reduced by the above control when the gate is switched, the gate control can be performed with almost no reduction in the processing capacity in the overall processing. It is possible to

FIG. 6 and FIG. 7 are operation flowcharts of the transport control according to the present invention. FIG. 6 is a processing flow of the judging section, and FIG. 7 is a control flow of the gate. Every time the banknote passes through the determination unit 8 (step 101), the banknote passes through the determination result (conveyance destination), the transport path deceleration timing when the gate is switched, the gate operation timing, and the transport path acceleration timing. The banknote NO. Set from 1 (step 10)
2). The gate control area 400 is an area of a memory built in the control unit. The control unit also includes a transport path counter 300. Here, the flow is about 1m
It is executed once every s, and the banknotes passing through the determination unit 8 can be constantly monitored. Banknote N
O. 1, the banknote B is deleted in the state of the transport path shown in FIG.
No. The data determination unit data of the banknote C is described as 2, and the banknotes D, E, and
It is described in the order of F ... Since the bill A has already passed through the gate, its description is omitted.

Next, referring to FIG. 7, the banknote NO. The processing proceeds while referring to the banknote data set to 1. First, the banknote NO. It is checked whether or not the bill B has reached the transport path deceleration timing by comparing the transport path deceleration timing of the bill B set to 1 and the value of the transport path counter 300 indicating the actual movement amount of the transport path ( Step 201). When the transport path deceleration timing is reached, the determination result (transport destination) is compared with the current state of the gate to determine whether or not the gate switching operation is necessary (step 202). When it is necessary to switch the gate, the transfer motor deceleration start (step 2)
03), the deceleration motor deceleration start (step 204) is executed (state of FIG. 2). Next, the conveyance path counter 300 is compared with the gate operation timing to determine whether or not the bill B has reached the gate operation timing (step 205), and when the gate operation timing is reached. To activate the gate (step 206). Before the bill B reaches the tip of the gate, the gate is completely switched, and the bill B is transferred to the destination without interfering with the gate (state shown in FIG. 3).

Next, when the bill B reaches the timing for accelerating the transport path near the tip of the gate (step 207), the transport motor 8 is accelerated and started (step 20).
8) The acceleration of the motor for the feeder roller is executed (step 209). As a result, the bill B is accelerated to a steady speed, and the gate control for the bill B ends. During the processing of the gate control flow, the determination section 8 executes the processing every 1 ms, so that the data of the banknote C passing through the determination section 8 during the gate control is processed. The banknote NO. It is set to 2. With the above, the gate control for the bill B is completed,
Banknote No. in the control area 400. The data of the banknote B set to 1 is deleted, and the banknote NO. The data of the banknotes set after 2 are set one by one (step 210). That is, the bill NO. The data of the banknote C set to 2 is banknote NO. It will be set in column 1. After this, the control proceeds to step 201.
Then, the gate control for the next banknote C is started (state of FIG. 4).

Although the gate operation timing 13 is always constant in FIGS. 2 to 4, it is not necessary to make it constant, and the timing may be varied depending on the transport speed. That is, the slower the transporting speed is, the closer it is to the front end of the gate. Therefore, for example, when the transporting speed varies depending on the size of the banknotes to be transported, the gate operation timing 13 may be changed for each transporting speed. Good gate switching control is possible. In the same way
Good gate switching can also be performed by changing the gate operation timing 13 depending on the state of the banknote determined to be rejected by the determination unit 8. For example, when the rejected banknotes are scarcely skewed, or even when skewed, the size of the banknotes in the lateral direction with respect to the transport direction is small, the gate operation timing 13 is set to the gate tip. You can get closer.

FIG. 5 is a block diagram of a conveyance control device showing an embodiment of the present invention. In FIG. 5, reference numeral 15 is a control unit that executes a transfer control program, 8 is a determination unit that detects the transfer status of banknotes, 6 is a transfer motor that drives a plurality of rollers on the transfer path, and 18 is a reject target. A gate driving solenoid for operating the gate, and a feed roller motor 17 for operating the feeder for feeding out the banknotes accumulated in the cassette one by one. The determination unit 8 includes a conveyance state detection sensor 81 for detecting the state of skew and the like, and a two-sheet detection sensor 8 for detecting double feed and the like.
2. A discrimination sensor 83 for determining the authenticity, the obverse and reverse sides of a bill, a stain, etc., and a bill passage sensor 84 for detecting the passage timing are built in. The determination unit 8 detects the state of the banknotes conveyed by the conveyance state detection sensor 81, the two-sheet detection sensor 82, and the discrimination sensor 83, and conveys the bills to the dispensing port stacker 7 or the reject box. It is determined whether the sheet is to be transported to 10. Both the determination result and the passage timing described above are sent to the control unit 15. The control unit 15 determines the conveyance destination of the banknote based on this determination result, and at the same time, determines the conveyance path deceleration timing 12, the gate operation timing 13 and the conveyance path acceleration timing 16 according to the flow shown in FIGS. 6 and 7. It is determined whether or not each bill has arrived, and each time, the solenoid for driving the transportation target or the motor for the feeder roller is individually controlled.

[0016]

As described above, according to the present invention,
In controlling the gate that switches the direction of the transport path, even when handling paper with large dimensions in the transport direction, the transport speed is increased, the gate solenoid is accelerated, and the processing capacity per unit time is reduced. On the contrary, it is possible to increase the number of sheets to be conveyed without doing so, so that it is possible to improve the processing of the apparatus.
