FIG. 1 has described the paper sheet transporting device 1 in one row of pachinko islands (island-like places where a plurality of pachinko machines are arranged back to back) in the hall.
FIG. 2 is an explanatory diagram exemplifying a laying route of the blower pipe 10 in the paper sheet transporting apparatus 1 for transporting and collecting the paper sheets from the pachinko island in the game hall to another safe room (collecting apparatus).

The airflow generation device 30 may be on the recovery device 40 side (not shown), or may be on both the control unit 100 side and the recovery device 40 side.

The blower pipe 10 has a horizontal pipe 14 extending from the vertical rising pipe 13 to the back of the ceiling via a bent portion, and the horizontal pipe 14 is stretched by a bent pipe 15 while avoiding a building structure such as a pillar. The recovery device 40 is reached via a bent pipe 16 that bends at a right angle and a vertical downcomer pipe 17. Reference numeral 18 denotes an exhaust pipe that exhausts the air flow through the separation unit of the recovery device 40. Further, 19 is a rack on which the recovery device 40 is mounted. In the paper sheet conveying apparatus 1 shown in FIG. 2, the air flow is not circulated and is discharged to the outside through the exhaust pipe 18.
Although not shown, it is preferable to provide a booster device for ejecting the compressed air flow into the blower pipe 10 at an appropriate position of the blower pipe 10 as an auxiliary device of the airflow generator 30.

Straight twisted tube (a straight tube twisted 90° clockwise (counterclockwise) around the axis of travel: Fig. 15), and other non-straight tubes.

In the paper sheet conveying apparatus 1 according to the present embodiment, the position A on the front side of the vertical rising pipe 13, which is an example of the portion of the blower tube 10 whose wind speed is to be controlled, and the portion of the blower tube 10 whose wind speed is to be controlled B position on the front side of the bent pipe 15 which is an example, and a C position which is the front side of the vertical downcomer pipe 17 which is an example of a portion of the blower pipe 10 whose wind speed is to be controlled, and which is also the front side of the recovery device 40. One or a plurality of detectors 25 for detecting banknotes are provided. It is preferable that the detection unit 25 is provided at a portion of the blower pipe 10 that is 3 to 4 m before the portion that controls the wind speed.

The detection unit 25 is composed of an optical sensor having a light emitting unit and a light receiving unit.
FIG. 3 shows an example of the detection unit 25. The detection unit 25 has a sensor including a light emitting unit and a light receiving unit, and is attached to both side walls of the blower pipe 10 by sandwiching the blower pipe 10 with a mounting bracket 26. The blower pipe 10 has a plurality of ribs 10b on both inner walls that protrude inward in parallel so that the bills do not stick to the wall surface. It is arranged so as to be located between them, and the light is emitted and received so as to pass through the outer wall of the blower tube 10. The detection unit 25 may be a sensor other than an optical sensor.

FIG. 4 shows still another embodiment of the detection unit 25.
In the present embodiment, the light emitting portion and the light receiving portion are attached so as to be positioned on both side walls of the two blower tubes 10 and the connecting tube 27 that connects the blower tubes 10.
In this case, if the connecting pipe 27 is made of a transparent material, the bills can be detected more favorably.

In the detection unit 25, the light is blocked by the bill 2 and the amount of light received by the light receiving unit is reduced, so that the bill 2 is detected. The detection signal from the detection unit 25 is input to the control unit 100.
Each detection unit 25 simply detects that the banknote 2 has passed and inputs this detection signal to the control unit 100.
Alternatively, the control unit 100 may calculate the transport speed of the banknote 2 based on the detection signal from each detection unit 25. In this case, the speed of the banknote 2 at each position may be calculated based on the time difference between the front end and the rear end of the banknote 2, or two detections may be made at each of the A position, the B position, and the C position. A unit (not shown) is provided at a required interval in the air blowing direction of the blower pipe 10, and the speed of the bill 2 at each position is calculated based on the time difference when the bill 2 passes between the two detection units. Good.

Subsequently, FIG. 5 shows a specific example of the recovery device 40. As the recovery device 40, a known recovery device as shown in Patent Document 3 can be used.
A brief description will be given below.
As shown in FIG. 5, the recovery device 40 includes a separating unit 50 that separates the banknote 2 conveyed in the blower tube 10 from the air flow, and a deforming unit of the banknote 2 separated from the air flow by the separating unit 50. It has a correction unit 70 for correcting 2b, and a storage unit 90 for storing the banknotes 2 separated from the air flow by the separation unit 50 and corrected by the correction unit 70.

In the separating unit 50, the airflow and the banknote 2 are separated, and the airflow is discharged to the outside through the exhaust pipe 18 (FIG. 2). The banknote 2 is guided and conveyed by the conveyor belt 51 disposed downstream of the separating unit 50, and is sent to the correction unit 70 by the roller 54. The straightening unit 70 has straightening rollers 71 arranged in a zigzag shape, and the bill 2 passes through the straightening roller 71 so that the bending (deformation) is straightened to form a flat bill 2, and the bill 2 is known. By the mechanism, they are sequentially stacked and stored in the storage section 90.

At the site of the collection device 40, a paper sheet detection sensor that detects the banknotes 2 conveyed into the collection device 40 is installed. For example, the paper sheet detection sensor is provided between the inlet sensor 43 (paper sheet detection sensor) that detects the banknote 2 and the correction unit 70 and the storage unit 90 before being separated from the air flow by the separation unit 50. It is provided and has a terminal sensor (not shown) for detecting the bill 2.

Although not shown in FIG. 5, a paper sheet detection sensor may be further installed between the separating unit 50 of the recovery device 40 and the correction unit 70. In this way, since the paper sheet detection sensor is installed between each of the separation unit 50, the correction unit 70, and the storage unit 90, it is possible to identify the place where the banknote 2 is jammed in the collection device 40.

As described above, the collection device 40 has a conveyance mechanism including belts and rollers such as the conveyance belt 51, the roller 54, and the straightening roller 71. Therefore, the conveyance speed of the banknotes 2 in the blower tube 10 and the collection operation. A large difference occurs in the transfer speed of the banknotes 2 in the device 40, and when the banknotes 2 enter the recovery device 40 at the transfer speed in the blower tube 10, the banknotes 2 are crushed and cause a jam. In particular, as shown in FIG. 2, when the blower pipe 10 immediately in front of the collection device 40 is the vertical downcomer pipe 17, the speed difference becomes large, the crushing phenomenon of the banknote 2 occurs, and the jamming phenomenon occurs. It was easy to occur.
On the other hand, when the blower pipe 10 in front of the collection device 40 is a vertically rising part (not shown), the conveyance speed of the banknote 2 becomes low, and in some cases, it may be close to a stopped state. There was also a cause of the clogging phenomenon in this case.

In addition, the flow of banknotes in the blower pipe 10 is not limited to the blower pipe 10 in front of the collection device 40, but also to the blower pipe 10, particularly to the portion of the vertical rising pipe 13 that rises toward the downstream side, to the downstream side. It changes at the part of the vertical descending pipe 17 that descends toward the bottom and the part at the bent portion 15. That is, since gravity acts on the portion of the vertical rising pipe 13, the conveyance speed of the banknotes 2 decreases, and the banknotes 2 easily accumulate, and sometimes the banknotes 2 are jammed. On the other hand, at the portion of the vertical downcomer 17, on the contrary, the conveyance speed of the banknotes 2 becomes too fast, and the banknotes 2 are deformed or crushed, so that the banknotes 2 cannot be smoothly conveyed. Become. Further, in the bent portion 15, since the conduit resistance to the banknotes 2 becomes large, the transportation speed of the banknotes 2 decreases, and the banknotes 2 cannot be smoothly transported due to the retention of the banknotes 2 and the jamming phenomenon easily occurs.

In view of this, in the present embodiment, first, the blower tube 10 at the A position, the B position, and the C position, which is on the front side of the portion where the wind speed is to be controlled, such as the vertical rising pipe 13, the bending pipe 15, the vertical descending pipe 17, and the like. A detection unit 25 for detecting the banknotes 2 conveyed in the blower pipe 10 is provided at the position of 1., and when the detection unit 25 detects that the banknotes 2 have passed through the region, an airflow is generated by the control unit 100. The air flow by the device 30 is changed to control the wind speed in the blower tube 10 to be slow or fast. The C position also serves as the front position of the recovery device 40.
The position where the detection unit 25 is provided is not limited to the positions A to C described above.

It should be noted that when the bill 2 passes through each of the above-mentioned positions and when it is collected in the collection device 40, the control unit controls a display device (not shown) that displays that the bill 2 has passed and that the bill 2 has been collected. It is preferable to provide it in the vicinity of 100. Accordingly, when the bill 2 is jammed, it is possible to easily determine at which position the bill 2 is jammed. For example, when the display indicates that the bill 2 has passed the A position but does not indicate that the bill 2 has passed the B position, the bill 2 is retained between the A position and the B position. Recognize.

Specifically, when the detection unit 25 detects that the banknote 2 has passed, the wind speed control by the airflow generation device 30 is performed in the case of the blower pipe on the front side of the collection device 40 or the vertical downcomer pipe 17. The wind speed in the vertical downcomer 17 is slowed down (first embodiment), and in the case of the vertical riser 13 and the bent pipe 15, the inside of the vertical riser 13 and the bent pipe 15 is increased. The wind speed is controlled so as to be faster (second embodiment).
Regarding the extent to which the wind speed in the blower tube 10 is slowed or increased, it is preferable that the characteristics of each paper sheet transporting device 1 be experimentally grasped in advance and that the speed be slowed or increased according to the characteristics.

Alternatively, the control unit 100 calculates the speed of the banknotes 2 conveyed in the blower tube 10 based on the detection signal input from the detection unit 25, and the airflow is calculated according to the calculated speed of the banknotes 2. The air flow generated by the generator 30 is changed to control the wind speed in the blower tube 10 to be slow or fast.
In this case, the speed of the banknote 2 is calculated by calculating the speed of the banknote 2 at each position based on the time difference between the front end and the rear end of the banknote 2 conveyed in the blower pipe 10 as described above. However, two detection units 25 are provided at each of the A position, the B position, and the C position, and each position is determined by the time difference that the banknote 2 passes between these two detection units. You may make it calculate the speed of the banknote 2 in (4th Embodiment).

FIG. 6 shows a flowchart in the first embodiment.
In the first embodiment, the blower pipe 10 immediately before the collecting device 40 is the vertical downcomer pipe 17 that descends toward the collecting device 40, or the part of the blower pipe 10 whose wind speed is to be controlled is located on the downstream side. In the case of a downcomer that descends toward the vertical downcomer 17, the wind speed in the vertical downcomer 17 and the downcomer is controlled so as to slow it down.
When the main switch (not shown) of the paper sheet transporting device 1 is turned on, the airflow generating device 30 such as a blower is in a standby state in which it is driven with a required output (step S10), and the operator can remove the bill 2 The output value (F) of the airflow generation device 30 during transportation is input to the control unit 100 (step S20).

When the bill 2 is inserted into the feeding device 20 (step S30), the airflow generation device 30 is driven by the output value F (step S40), and the bill 2 is conveyed in the blower pipe 10.
When the detection unit 25 confirms the passage of the banknote 2 (step S50), the detection signal is input to the control unit 100, and the control unit 100 causes the airflow generation device 30 to reduce the output by a preset amount α. Is reduced and the airflow generator 30 is driven by the output of F-α (step S60).

The output reduction amount α has been experimentally obtained in advance and is input to the control unit 100. That is, in advance, when the output of the airflow generator 30 is reduced in a required plurality of steps to convey a plurality of banknotes 2, the flow of the banknotes 2 in the bending tube 15 and the vertical downcomer 17 (the transfer speed is Whether the bill 2 is deformed or crushed too fast) is verified for each output stage, and the collection device 40 verifies the jam condition of the bill 2 for each output stage, and the deformed bill 2 is deformed. It is necessary to obtain a good output reduction amount α that does not cause crushing or clogging. It is needless to say that the decrease α of the output is obtained for each model of the sheet conveying device 1 in which the laying route of the blower pipe 10 is different.

When the required set time has elapsed (step S70), the output of the airflow generation device 30 is returned to F (step S80), and when the collection of banknotes in the collection device 40 is completed (step S90), the output of the airflow generation device 30 is changed. The process returns to the standby state (step S100) and ends if necessary.

FIG. 7 shows a flowchart in the second embodiment.
In the second embodiment, when the blower pipe 10 immediately before the collecting device 40 is an ascending pipe that rises toward the collecting device 40, or when the part of the blower pipe 10 whose wind speed is to be controlled is directed toward the downstream side. In the case of the rising vertical rising pipe 13, the vertical rising pipe 13 and the rising pipe are controlled so as to increase the wind speed.
In the present embodiment, in Step 60, the output of the airflow generation device 30 is increased by the increase α of the output to drive the airflow generation device 30, and only in the point that the first embodiment shown in FIG. 6 is used. Be different.
Also in the present embodiment, the increase amount α of the output is obtained in advance by carrying out a transportation test of a plurality of banknotes 2. That is, the increase amount α of the output is obtained in advance so that the bill 2 does not stay in the vertical rising pipe 13 and the required conveyance speed is achieved.

In FIG. 8, the control unit 100 calculates the speed of the banknotes 2 conveyed in the blower tube 10 based on the detection signal input from the detection unit 25, and according to the calculated speed of the banknotes 2, The third embodiment in which the airflow generated by the airflow generator 30 is changed to control the wind speed in the blower pipe 10 to be slow or fast (a single detection unit 25 is provided at each position of A to C). The flowchart in FIG.

When the main switch (not shown) of the paper sheet transporting device 1 is turned on, the airflow generating device 30 such as a blower is in a standby state in which it is driven with a required output (step S110), and the operator can remove the bills 2 The output value (F) of the airflow generator 30 during transportation is input to the control unit 100 (step S120). Further, the operator inputs the set transport speed Sa of the banknote 2 to the control unit 100 (step S130).

The set transport speed Sa is experimentally obtained in advance for each detection position of the A position, the B position, and the C position. That is, the output of the airflow generation device 30 is increased or decreased in required plural steps, the plural banknotes 2 are conveyed at the required plural stages of speed, and the conveyance test is performed, and the position A (the position before the vertical rising pipe 13 is measured). ), an average transport speed Sa that does not cause retention or jamming of the banknotes 2 is obtained in advance, so that the banknotes 2 do not have an unnecessarily high speed at the B position and the C position, that is, the deformation of the banknotes 2 An average transport speed Sa that does not cause crushing or crushing is obtained in advance, and an average transport speed that does not cause jamming of the banknotes 2 in the collection device 40 at a position before the collection device 40, if necessary. Sa is obtained in advance, and the control unit 100 inputs the set transport speed Sa for each of the detection units 25 at the A position, the B position, the C position, and the front position of the recovery device 40. Such a set transport speed Sa is obtained for each model of the paper sheet transporting apparatus 1.

When the bill 2 is inserted into the feeding device 20 (step S140), the airflow generation device 30 is driven at the output value F (step S150), and the bill 2 is conveyed in the blower pipe 10.
When the detection unit 25 confirms the passage of the bill 2 (step S160), the detection signal is input to the control unit 100, and the control unit 100 causes the front end and the rear end of the bill 2 conveyed in the blower pipe 10. The speed Sb of the banknote 2 is calculated by the time difference between the passages (steps S170 to S190).

Next, the control unit 100 determines whether the actual passing speed Sb of the banknote 2 when passing through the detection unit 25 is outside the range of Sa±τ (τ is a predetermined margin value) (step S200). -Step S210).
When Sb>(Sa+τ), the output value F in the airflow generation device 30 is reduced to reduce the conveyance speed of the banknote 2 (step S220), and then the banknote 2 is recovered by the recovery device 40 (step S230). .. When Sb<(Sa−τ), the output value F in the airflow generation device 30 is increased to increase the conveyance speed of the bill 2 (step S240), and then the bill 2 is collected by the collection device 40 (step S230). ). In this case, it is preferable that the increase/decrease of the output F in the airflow generation device 30 is also obtained in advance according to the size of the bill transport speed Sb.

In step S200, when the actual passing speed Sb of the banknote 2 is within the range of Sa±τ, the banknote 2 is recovered by the recovery device 40 while the output F of the airflow generation device 30 remains unchanged (step S230). ..
After collecting the bill 2, the output of the airflow generation device 30 is returned to the standby state (step S250). Then, the process ends if necessary.

In FIG. 9, the control unit 100 calculates the speed of the banknotes 2 conveyed in the blower tube 10 based on the detection signal input from the detection unit 25, and according to the calculated speed of the banknotes 2, The fourth embodiment in which the airflow generated by the airflow generator 30 is changed to control the wind speed in the blower tube 10 to be slowed or fast (the detection unit 25 at each position of A to C is 2) Location).

In the present embodiment, in the control unit 100, when the upstream detection unit 25 detects the banknote 2 in step S160, the banknote transport speed measurement is started in step S165, and the downstream detection unit 25 in step S170. When 2 is detected, the transport speed of the banknote 2 is calculated based on the detection time difference between the two detection units, and the transport speed Sb of the banknote 2 is acquired (steps S180 and S190).
The other steps are the same as the steps in FIG.

In each of the above-described embodiments, the detection unit 25 is set to the position A (vertical ascending pipe 13), the position B (bending pipe 15), and the position C (vertical descending pipe 17) of the part where the wind speed of the blower tube 10 should be controlled. Provided. When there is only one bill 2 in the blower pipe 10, the above control may be performed in order at each of the above positions.
When there are a plurality of banknotes 2 in the blower pipe 10, it is preferable to determine the priority order among the A position, the B position, and the C position in advance and perform the above control. For example, when the A position is given the highest priority, and when the banknotes 2 are conveyed to the A position and the B position at the same time, the control at the A position is prioritized over the B position.

In the case of the A position, that is, in the case of the vertical rising pipe 13, the bills 2 may be stagnant, so that the priority is to increase the wind speed. In this case, at other positions, the wind speed may increase more than necessary. It depends on what is the priority, but it will be decided on a case-by-case basis according to the importance.
In particular, as described above, due to the difference in the transport mechanism, the bill 2 is likely to be jammed in the collection device 40, and the maintenance when the jam is caused is the most troublesome. Therefore, the above control in front of the collection device 40 is performed. It is preferable to give priority to other parts.

In the above-described embodiment, the detection unit 25 is provided at the A position (vertical ascending pipe 13), the B position (bending pipe 15), and the C position (vertical descending pipe 17). It may be provided at only one place.
