First, the overall configuration of the paper leaf transport system 1 in the present embodiment will be described with reference to FIGS. 1 and 2. As for the paper leaf transport system 1, the technique proposed by the present inventor in Patent Document 1 and the like can also be referred to.
In the following, banknotes will be described as examples of paper leaves.

As shown in FIG. 1, in the paper leaf transport system 1, for example, the air flow generated by the air flow generator 30 such as a blower is the delivery pipe 31, the connecting pipe 32, the blow pipe 10, the recovery device 40, and the return pipe 33. It is configured to circulate through. In order to form this circulation path, the blower pipe 10 is formed with a bent pipe 10a bent in a U shape. Further, at an appropriate position of the blower pipe 10, a plurality of feeding devices 20 for sending bills 2 into the blower pipe 10 are installed. The air flow generator 30, the delivery pipe 31, the connecting pipe 32, the return pipe 33, and the recovery device 40 are installed inside the housing 49, and the blower pipe 10 and the feeding device 20 are installed outside the housing 49, for example. ..

The feeding device 20 has a bill identification device 21 installed on the front side of feeding and a bending device 22 installed on the back side and connected to the blower pipe 10. The bending device 22 constituting the feeding device 20 forms a zigzag-shaped deformed portion 2b (which is a bent portion) at the rear end portion in the transport direction with respect to the flat surface portion 2a at the front end portion in the transport direction of the bill 2. Is. The wind pressure from the air flow (indicated by an arrow in FIG. 1) flowing in the blower pipe 10 acts on the deformed portion 2b, and the bill 2 is conveyed in the blower pipe 10.

Further, the recovery device 40 includes a separation unit 50, a straightening unit 70, and a storage unit 90 installed in the order of transportation from the terminal end side of the blower pipe 10. Of these, the separation unit 50 separates the banknote 2 conveyed in the blower pipe 10 from the air flow that has given propulsive force to the banknote 2, and sends the banknote 2 to the correction unit 70. Further, the straightening section 70 corrects the deformed section 2b of the bill 2 sent out from the separating section 50. Further, the storage unit 90 stores the banknote 2 separated from the air flow by the separation unit 50 in a stretched state (flattened state) after correcting the deformation of the deformation unit 2b via the correction unit 70. Is.

FIG. 1 describes a paper leaf transport system 1 on a row of pachinko islands (island-shaped locations where a plurality of pachinko machines are arranged back to back) in a game hall.
However, instead of the system for collecting banknotes 2 in the same room by the collection device (safe) 40, the collection device 40 is arranged in a separate room (not shown), and the blower pipe 10 crawls along the wall surface or the ceiling. It may be a system that is provided together and guided to a collection device 40 provided in a separate room for collection.

FIG. 2 shows a specific example of the recovery device 40. As the recovery device 40, a known recovery device as shown in Patent Document 1 can be used.
The following is a brief explanation.
In the separation unit 50, the air flow and the bill 2 are separated, and the air flow is discharged to the outside from an exhaust pipe (not shown). The bill 2 is guided and transported by a transport belt 51 arranged downstream of the separation section 50, and is sent to the straightening section 70 by a roller 54. The straightening portion 70 has a straightening roller 72 arranged in a zigzag shape, and the bill 2 is bent (deformed) by passing through the straightening roller 72 to be straightened into a flat bill 2. By the mechanism, they are sequentially stacked and stored in the storage unit 90.

Reference numeral 60 is a motor for driving the transport belt 51 and the roller 54.
The storage portion 90 has a press plate 96 that is moved up and down by a motor 98, and a receiving plate 94 that is urged upward by a spring 92.
At the site of the collection device 40, a paper leaf detection unit for detecting the bill 2 conveyed in the collection device 40 is installed. For example, the paper leaf detection unit is provided between the inlet sensor 43 (detection unit) that detects the bill 2 and the straightening unit 70 and the storage unit 90 before being separated from the air flow by the separation unit 50. It has a terminal sensor 44 and the like for detecting the bill 2.

As described above, the paper leaf transport system 1 forms the blower pipe 10 in which the paper leaves are conveyed by the air flow and the deformed portion 2b at the rear end portion of the bill 2 to feed the bill 2 into the blow pipe 10. The feeding device 20, the air flow generating device 30 that causes the bill 2 to generate an air flow in the blowing pipe 10 by applying wind pressure to the deformed portion 2b of the bill 2, and the blowing pipe 10 installed at the end of the blowing pipe 10. It is provided with a collection device 40 for collecting the bills 2 carried inside. Further, the paper leaf transport system 1 includes a control unit 100 that controls devices such as an air flow generator 30, a feeding device 20, and a collecting device 40 (see FIG. 3). In such a paper leaf transport system 1, a transport path is configured in the order of a blower pipe 10, a separation section 50, a straightening section 70, and a storage section 90 from a feeding device 20 into which bills 2 are inserted, and the bills 2 are conveyed. Transported by road.

As shown in FIG. 3, the control unit 100 includes a feeding device 20 via the loop communication line 25, a display device 103 for displaying various states of the paper leaf transport system 1 via the communication line 101, and a communication line 102. It is electrically connected to the recovery device 40 via. As described above, in the paper leaf transport system 1, a device such as a feeding device 20 is constructed in a wiring system including a paper leaf detection unit and the like, centering on a control unit 100. The control unit 100 has a control function for controlling a device such as a feeding device 20 via a wiring system. In the present application, the ON state of the paper leaf detection unit means a state in which the bill 2 is detected, and the opposite state to the OFF state.

The control unit 23 of the feeding device 20 is fed into the blowing tube 10 at the site of the inlet sensor 26 that detects that the bill 2 has been inserted into the feeding device 20 and the blowing tube 10 to which the feeding device 20 is connected. The outlet sensor (detection unit) 27 that detects the bill 2 and the staying state of the bill 2, the feed motor 28 of the bending device 22, and the control unit 29 of the bill identification device 21 are electrically connected. There is. Further, the display device 103 includes an indicator light (for example, an LED) that lights up in an error state such as a normal operation state or an error state such as when a jam of bill 2 is detected, an alarm that warns, a reset button for the display device, and a display device. It has a power switch and so on.

The control unit 100 further has the following basic functions (basic form).
That is, a counter addition function that adds 1 to the counter when it is detected by the outlet sensor 27 in the feeding device 20 that the bill 2 has been sent into the blower pipe 10 (the sensor is turned from ON to OFF).
When the bill 2 is sent to the storage unit 90 by the termination sensor 44 in the collection device 40 and it is detected that the bill 2 has been collected (the sensor is turned from ON to OFF), 1 is subtracted from the counter.
A discharge prohibition function that prohibits the discharge (sending) of the bill 2 into the blower pipe 10 when the value of the counter exceeds the specified value (K),
It has a discharge permission function that permits the discharge of the bill 2 into the blower pipe 10 when the value of the counter does not exceed the specified value (K).

Further, when the value of the counter exceeds the specified value (K), the control unit 100 may display on the display device 103 to give a warning, and may stop a part or all of the device in some cases. ..
As described above, the control unit 100 controls so that the number of bills 2 is always within the specified number in the blower pipe 10. As a result, the bill 2 can be conveyed in the blower pipe 10 with a stable conveying force.
For the above series of controls, the functions detailed in Patent Document 1 can be adopted as they are.
In the present embodiment, the value of the counter exceeds the specified value (K), the discharge of the bill 2 from the feeding device 20 into the blower pipe 10 is prohibited, and the number of bills 2 in the standby state is waited for. It is designed to be counted by a counter.

FIG. 4 is a flowchart showing a first embodiment of a control example in the control unit 100.
When the main switch (not shown) of the paper sheet transport system 1 is turned on, the air flow generator 30 is in a standby state (step S10) driven by the required output (F).
In the feeding device 20, when the control unit 100 is notified by the outlet sensor 27 that the bill 2 has been fed into the blower pipe 10 (step S12), the control unit 100 sets the output of the air flow generating device 30 from F. The output F + α is increased by the value α, and the wind speed in the blower pipe 10 is controlled to be increased by this (step S14). When the bill 2 is discharged into the blower pipe 10, the transport load increases and the wind speed decreases accordingly. Therefore, the output of the air flow generator 30 is increased to compensate for the wind speed.

The increase α of the output is obtained on a trial basis in advance and is input to the control unit 100. The set value α may be a constant value or may be increased according to the number of sheets to be released (sent).
When the terminal sensor 44 detects that the banknote 2 discharged into the blower pipe 10 has been collected by the collection device 40, the output is reduced, and when the conveyed banknote 2 becomes zero, the device waits. Return to output F.

This embodiment may be performed in addition to the above-mentioned basic functions in the control unit 100. That is, even if the number of bills 2 existing in the blower pipe 10 is within the specified value (K), the output of the air flow generator 30 is increased or decreased if the bills 2 are released or collected.
As a result, finer control is possible, and the transport function of the bill 2 can be stabilized.
Alternatively, the present embodiment may be adopted regardless of the above basic functions. That is, simply, when the bill 2 is discharged into the blower pipe 10 and when the bill 2 is collected, the output of the air flow generator 30 is increased or decreased, and the wind speed in the blower pipe 10 is changed. There may be.

FIG. 5 is a flowchart showing a second embodiment of a control example in which further control is added in addition to the above basic functions in the control unit 100.
In the present embodiment, in the feeding device 20, the outlet sensor (detection unit) 27 is in the ON state, that is, a specified number (K) of bills 2 are discharged into the blower pipe 10, and more bills 2 are blown out. It is an embodiment about the control of the air flow generator 30 in the standby state in which the release into the inside is prohibited.

When the bill 2 is in the standby state, one end of the bill 2 is sandwiched and held by a feeding roller (not shown) in the feeding device 20, and in this case, the other end of the bill 2 is partially blown. It is in a state of being discharged into the pipe 10. Therefore, even when the bill 2 is in such a standby state, it becomes a blower resistance and the transport function of the bill 2 in the blower pipe 10 is deteriorated.
Therefore, in the present embodiment, when the outlet sensor 27 notifies the control unit 100 of the prohibition (standby state) of feeding the bill 2 into the blower pipe 10 in the feeding device 20 (step S16), the control unit 100 causes the control unit 100 to notify the control unit 100. The output of the air flow generator 30 is set to the output F + α which is increased by the set value α from F, and the wind speed in the blower pipe 10 is controlled to be increased (step S18).

Also in this embodiment, the set value α may be a constant value or may be increased according to the number of bills 2 in the standby state.
When the bill 2 in the standby state becomes zero, the output of the air flow generator 30 is returned to the standby output F.
The first embodiment and the second embodiment may be implemented together.

FIG. 6 is a flowchart showing the third embodiment.
As described above, since the collection device 40 is a transfer mechanism composed of belts and rollers such as a transfer belt 51, a roller 54, and a straightening roller 72, the transfer speed of the banknote 2 in the blower pipe 10 and the collection rate. There was a large difference in the transport speed of the bill 2 in the device 40, and when the bill 2 entered the collection device 40 at the transport speed in the blower pipe 10, the bill 2 was crushed and caused clogging. In particular, as shown in FIG. 2, when the blower pipe 10 immediately before the collection device 40 is a vertical descending pipe, the speed difference becomes large, a crushing phenomenon of the bill 2 occurs, and a clogging phenomenon occurs. It was easy. Further, in the first embodiment and the second embodiment, when the output of the air flow generator 30 is increased and the wind speed in the blower pipe 10 is increased, the speed difference becomes large and the inside of the recovery device 40. The clogging phenomenon of the banknote 2 in the above is likely to occur.

Therefore, in the present embodiment, when the passage of the bill 2 is confirmed by the inlet sensor (detection unit: not shown) provided in the blower pipe 10 in front of the collection device 40 (step S20), the detection signal is transmitted to the control unit 100. The control unit 100 reduces the output of the air flow generator 30 by the amount β of the preset output decrease, and drives the air flow generator 30 with the output of the F−β (step S22). ). As a result, the speed of the banknote 2 sent to the collection device 40 is reduced to the required speed, and the jamming phenomenon of the banknote 2 in the collection device 40 can be suppressed. When it is detected by the terminal sensor 44 that the bill 2 has been collected by the storage unit 90, the output of the air flow generator 30 is returned to the standby output F.
The amount of decrease β in the output is obtained on a trial basis in advance and is input to the control unit 100.

FIG. 7 is a flowchart showing the fourth embodiment.
When the blower pipe 10 immediately before the recovery device 40 is a vertical rising pipe (not shown), the wind speed in the blower pipe 10 is as in the first embodiment and the second embodiment. Even when the speed is increased, the transport speed of the bill 2 in the collection device 40 becomes too low, which also contributes to the jamming phenomenon of the bill 2.

Therefore, in the present embodiment, when the passage of the bill 2 is confirmed by the inlet sensor (detection unit: not shown) provided in the blower pipe 10 in front of the collection device 40 (step S24), the detection signal is transmitted to the control unit 100. The control unit 100 increases the output of the air flow generator 30 by the amount α of the preset output increase, and drives the air flow generator 30 with the output of F + α (step S26). As a result, the speed of the banknote 2 sent to the collection device 40 increases to the required speed, and the jamming phenomenon of the banknote 2 in the collection device 40 can be suppressed. The increase α of the output may be obtained on a trial basis in the same manner as in the third embodiment. When it is detected by the terminal sensor 44 that the bill 2 has been collected by the storage unit 90, the output of the air flow generator 30 is returned to the standby output F.

FIG. 8 is a flowchart showing the fifth embodiment.
In the present embodiment, when the bill 2 is newly sent out into the blower pipe 10, the difference between the number of bills 2 sent into the blower pipe 10 and the number of bills 2 collected by the collection device 40 is calculated and actually The output of the air flow generator 30 is controlled by the number of bills 2 transported in the blower pipe 10.

That is, when the outlet sensor (detection unit) 27 detects in step S30 that the bill 2 has been fed into the blower pipe 10 by the feed device 20, the control unit 100 blows the bill 2 up to that point. The cumulative number of bills sent into the pipe 10 A (the amount of newly detected bills 2 is +1) and the cumulative number of bills 2 collected by the collection device 40 up to that point B (new bills 2 are The difference from (1 is considered to be +1 when collected) is calculated, and the number C of the banknotes 2 being conveyed in the blower pipe 10 is calculated (step S32).

Then, when it is determined in step S34 that the number C of the banknotes 2 being conveyed is larger than the specified number K, the control unit 100 sets the output of the air flow generator 30 to the output F + α which is increased by the set value α from F. As a result, the wind speed in the blower pipe 10 is controlled to be increased (step S36).
The set value α may be a constant value or may be increased according to the number of bills 2 larger than the specified number K.

In step S34, when the number C of the bills 2 being conveyed in the blower pipe 10 is the specified number K or less, the output of the air flow generator 30 remains F (step S38) and in the blower pipe 10. When the number C of the banknotes 2 being transported becomes zero (step S40), the output of the air flow generator 30 is set to the output in the standby state (step S42), and the collection of banknotes 2 by the collection device 40 is completed.

In the present embodiment, even in the case of the basic function (basic form) for prohibiting the feeding of banknotes 2 having a specified number of sheets K or more into the blower pipe 10, the banknotes 2 having a specified number of sheets K or more are mistakenly inserted into the blower pipe 10. It is effective in that case because it may be sent inside.
Alternatively, the present embodiment is particularly effective in the case of the embodiment in which the number of bills 2 to be sent into the blower pipe 10 is not particularly limited, instead of the above-mentioned basic function.

FIG. 9 is a flowchart showing the sixth embodiment.
This embodiment is the case of the basic function (basic form) for prohibiting the feeding of banknotes 2 having a specified number of sheets K or more into the blower pipe 10, and the number of banknotes 2 in the standby state and the collection by the feeding device 20. The output of the air flow generator 30 is controlled by the difference from the number of bills 2 collected by the device 40.

That is, when the banknote 2 newly in the standby state in the feeding device 20 is detected by the exit sensor (detection unit) 27 in step S44, the control unit 100 waits for the number of banknotes 2 (newly on standby banknotes A). When 2 is detected, it is set to +1), and the difference between the number of bills 2 newly collected by the collection device 40 and the collection number B is calculated (step S46). In the basic function, when the banknote 2 in the standby state exists, when the banknote 2 is newly collected by the collection device 40, the banknote 2 in the standby state is sent out into the blower pipe 10 each time. The difference between B is calculated, and the number of bills 2 actually in the standby state is calculated.

Then, when it is determined in step S48 that the number C of the waiting bills 2 is larger than the predetermined number K, the control unit 100 sets the output of the air flow generator 30 to the output F + α which is increased by the set value α from F. As a result, the wind speed in the blower pipe 10 is controlled to be increased (step S50). Even when the bill 2 is in the standby state, it becomes a resistance of the air flow in the blower pipe 10, so that the output of the air flow generator 30 is increased, whereby the bill 2 can be stably conveyed.
The set value α may be a constant value or may be increased according to the number of bills 2 larger than the specified number K.

In step S48, when the number C of the banknotes 2 in the standby state is equal to or less than the specified number K, the output of the air flow generator 30 remains F (step S52), and the number of banknotes 2 in the standby state C. When becomes zero (step S54), the output of the air flow generator 30 is set to the standby state output (step S56), and the control of the air flow generator 30 ends.
