Abstract

A device for conveying banknotes through a carrier by means of an airflow generated in a duct, in which backflow of the airflow is prevented. A shield plate (510) is arranged inside a banknote passage (240A). The shield plate (510) slides and rotates in the long hole (241A). When the backflow (Wa) of the airflow enters the banknote passage (240A), the shielding plate (510) rotates under the wind pressure of the backflowing airflow (Wa) to shield the banknote passage (240A). As a result, the backflowing airflow (Wa) can be stopped by the shielding plate (510). [Selection drawing] Fig. 19

The stoppers 13 a and 13 b are hook-shaped members extending inside the duct 11 . The first wing 10b of the carrier 10 is caught by the stopper 13a, so that the carrier 10 stops before the bill storage chamber 14.例文帳に追加Further, the second wing 10c of the carrier 10 is caught by the stopper 13b, so that the carrier 10 stops before the first blower 12a.

The paper sheet conveying device having the structure described above operates as follows.
When a customer of the pachinko machine 20 inserts a banknote into the banknote slot 21a of the banknote input device 21, the banknote is transported by the roller unit 21b and is input into the duct 11 from the slit 11b of the duct 11 via the transport path 21c. be.
The banknote insertion device 21 is provided with a banknote detection sensor (not shown). When a banknote is inserted into the duct 11, the banknote detection sensor sends a banknote insertion signal to the central control unit (not shown). (not included).
The central controller that receives the banknote insertion signal operates the first blower 12a. When the first blower 12a starts operating, an air flow (wind) is generated inside the duct 11 in the direction (direction X1) toward the banknote storage chamber 14 . The carrier 10 travels in the direction (direction X1) toward the banknote storage chamber 14 by the second wing 10c receiving wind pressure from this air flow. The carrier 10 captures bills inserted into the duct 11 with the first wing 10b before reaching the bill storage chamber 14.例文帳に追加The carrier 10 that has captured the banknotes continues to travel in the direction (direction X1) toward the banknote storage chamber 14 while maintaining the state of pushing the captured banknotes, and then is stopped by the stopper 13a. When the carrier 10 stops, the banknotes are separated from the carrier 10 by the action of inertia and are accommodated in the banknote storage chamber 14 .

The banknotes are conveyed by the carrier 10 while maintaining a posture in which the paper surface is parallel to the running direction of the carrier 10 (longitudinal direction of the duct 11) and the short side is parallel to the central axis 10a of the carrier 10. be.
A sensor (not shown) for detecting the carrier 10 is arranged near the stopper 13a. When the carrier 10 is stopped by the stopper 13a, the sensor outputs a carrier stop signal indicating that the carrier 10 is stopped by the stopper 13a. Send to central controller.
Upon receiving the carrier stop signal, the central control unit stops the operation of the first blower 12a and waits a predetermined time after the carrier 10 is stopped by the stopper 13a (the time required for bills to be stored in the bill storage chamber 14). ) has passed, the second blower 12b is operated.

When the second blower 12b starts to operate, an air flow (wind) is generated inside the duct 11 in a direction (direction X2) away from the banknote storage chamber 14 . The carrier 10 travels in the direction (direction X2) away from the banknote storage chamber 14 by the first wing 10b receiving wind pressure from this airflow.
After that, the carrier 10 is caught by the stopper 13b and stopped. In this way the carrier 10 returns to its original position.
The above operation is one cycle operation from when the bill is inserted into the bill inserting device 21 until it is stored in the bill storage chamber 14 .

As described above, when the shielding plate 510 is at the first position (FIG. 18), the shielding plate 510 maintains the open state without blocking the second banknote path 240, and the shielding plate 510 is at the second position ( 19), the shield plate 510 shields the second banknote passage 240. As shown in FIG. The second extension part 243B is formed so that the shielding plate 510 does not interfere with the inner wall of the second banknote passage 240 even if the tip of the shielding plate 510 rotates when the shielding plate 510 moves from the first position to the second position. It is what was done.
20 to 24 are cross-sectional views showing the operation of the banknote shaping apparatus 200 according to this embodiment. The operation of the banknote shaping apparatus 200 will be described below with reference to FIGS. 20 to 24. FIG.
As shown in FIG. 20 , the banknote 50 sent from the banknote insertion device 21 is sandwiched between a pair of banknote take-in rollers 210 and taken into the banknote shaping device 200 . At this stage, shield plate 510 is in the first position (the position of FIG. 18).

26 to 29 are perspective views showing how the bill 50 is straightened by the pair of bill shaping rollers 220. FIG.
For example, the curved or bent banknote 50 passes between the first roller 220A and the second roller 220B that constitute the pair of banknote shaping rollers 220, and the unevenness 221 of each of the two rollers 220A and 220B Pushing forces are applied in mutually different directions. Specifically, the first roller 220A exerts a pressing force on the banknote 50 in the direction from right to left by the protrusions of the unevenness 221, and the second roller 220B is directed from left to right by the protrusions of the unevenness 221. A pressing force is applied to the bill 50 in the direction. In this way, the banknote 50 receives the pressing force from right to left and the pressing force from left to right in a zigzag manner. It will be almost straight to the extent that there is no

For example, as shown in FIG. 26, a banknote 50A that has been folded in four so that the bend line is parallel to the long side 50b of the banknote 50 is a banknote 50B that leaves traces of folding even when the banknote 50A is unfolded from the folded state. become. The banknote 50B is inserted into the banknote insertion device 21 in this state, and then sent to the banknote shaping device 200 . By passing the banknote 50B through a pair of banknote shaping rollers 220, the bending marks are corrected, and the banknote 50B becomes a substantially straight banknote 50C. This banknote 50C is sent to the inside of the duct 120 via the second banknote passage 240 .
Further, as shown in FIG. 27, a banknote 50D that is folded in four so that the bend line is parallel to the short side 50a of the banknote 50 has a banknote 50E in which traces of folding remain even when the banknote 50D is unfolded from the folded state. become. As in the case of the banknote 50B shown in FIG. 26, the banknote 50E passes through a pair of banknote shaping rollers 220, thereby correcting the bending marks and forming a substantially straight banknote 50F. This banknote 50F is sent to the inside of the duct 120 via the second banknote passage 240 .

FIG. 28 shows a banknote 50G whose long side 50b is curved (curled), and FIG. 29 shows a banknote 50H whose short side 50a is curved (curled).
Even if the banknotes 50G and 50H are curved in any direction as described above, the curvature is corrected by passing through the pair of banknote shaping rollers 220, and the banknote 50J is substantially straight.
The banknotes 50 straightened substantially straight by the pair of banknote shaping rollers 220 are sent from the pair of banknote shaping rollers 220 to the banknote delivery rollers 250 via the second banknote passage 240, as shown in FIG.
As shown in FIG. 23, the banknotes 50 sent to the banknote delivery rollers 250 are sandwiched between the banknote delivery rollers 250 and the pressing plates 260A of the pair of banknote pressing plates 260, and are directed toward the duct 120 in this state. sent.

Next, as shown in FIG. 24, the banknotes 50 are fed into the second area 120b of the duct 120. As shown in FIG. After that, the banknotes 50 are captured by the carrier 110 and transported to the banknote storage chamber 14 .
Inside the duct 120, an air flow W for sending the carrier 110 flows toward the bill storage chamber 14. - 特許庁As shown in FIG. 25 , part of this airflow W may enter the second banknote passage 240 and flow back through the second banknote passage 240 as an airflow Wa.
As shown in FIG. 18, the airflow Wb, which is part of the backflowing airflow Wa, enters the gap T formed between the shielding plate 510 and the inner wall of the first extended portion 243A. Since the airflow Wb that has entered the gap T has no other escape, it acts on the shielding plate 510 as a wind pressure that pushes the shielding plate 510 from left to right and from top to bottom at the same time.

The shielding plate 510, which receives wind pressure from the airflow Wb, slides in the long holes 241A and 241B from left to right and simultaneously rotates counterclockwise around the projection 520. As shown in FIG. As a result, as shown in FIG. 19, the shield plate 510 moves from the left end to the right end of the elongated holes 241A and 241B and stops at the second inclined portion 2404 of the second extended portion 243B.
As described above, as shown in FIG. 25, the shield plate 510 is moved from the first position (the position shown in FIG. 18) to the second position (the position shown in FIG. 19) by the air flow Wb that is part of the backward air flow Wa. , and shields the second banknote passage 240 . Therefore, the backflowing air flow Wa is blocked by the shielding plate 510, and the subsequent backflow can be stopped.
The shielding plate 510 moved to the second position is pushed by the next conveyed banknote and returns to the first position.

The operation described above is one cycle operation until the banknote 50 inserted into the banknote inserting device 21 is fed into the duct 120 via the banknote shaping device 200 . After that, this operation is repeated.
The paper sheet conveying apparatus 100 according to this embodiment has the following effects.
In the paper sheet conveying apparatus 100 according to the present embodiment, even if the air flow Wa inside the duct 120 flows backward through the second bill passage 240 after sending out the bills 50 to the duct 120, the shield plate 510 will flow backward. Due to the wind pressure of the air flow Wa, the second banknote path 240 is shielded from the first position to the second position. Therefore, the shielding plate 510 stops the backflow of the backflowing air flow Wa.
Therefore, even if the next inserted banknote passes through the first banknote passage 230, this banknote will not be affected by the air flow Wa.

The paper sheet conveying apparatus 100 according to this embodiment is not limited to the above structure, and various modifications are possible.

None of the pair of transport rollers 410 and the pair of banknote shaping rollers 420 are in a stationary state. The shield plate 560 is in the first position (the position of Figure 52).
The banknotes 50 passing through the second area 120b of the first duct 1201 enter the banknote passage 430, pass between a pair of transport rollers 410 separated from each other as shown in FIG. It hits the shaping rollers 420 and is sandwiched between the pair of banknote shaping rollers 420 .
As shown in FIG. 55, the carrier 110 carrying the bills 50 enters the carrier storage duct 130 from the first duct 1201 and stops inside the carrier storage duct 130 .

When the banknote 50 reaches the pair of banknote shaping rollers 420, a banknote detection sensor (not shown) detects this and sends a banknote arrival signal to the central controller (not shown).
Upon receiving the banknote arrival signal, the central controller stops the operation of the first blower 12a and rotates the banknote shaping roller 420 in the reverse direction S2 (see FIG. 48), as shown in FIG. As a result, the second roller 410B of the transport roller 410 rotates together with the connecting member 440 and comes into contact with the first roller 420A (the state shown in FIG. 48). In this state, the banknote 50 is sandwiched between the pair of banknote shaping rollers 420 at the front and between the pair of transport rollers 410 at the rear.

The central controller then activates drive motor 470 . Thereby, as shown in FIG. 57, the banknote 50 is transported forward by the transport roller 410 and the belt 472 and begins to pass through the pair of banknote shaping rollers 420 .
As the banknote 50 advances further, as shown in FIG. 58, the trailing edge of the banknote 50 leaves the transport roller 410 and the leading edge advances into the second duct 1202 via the banknote delivery roller 450 and the banknote holding plate 460. start.
Next, as shown in FIG. 59, the banknote 50 leaves the pair of banknote shaping rollers 420 and is sent to the banknote delivery roller 450 and the banknote holding plate 460, and most of the banknote 50 enters the second duct 1202. do.
Then, as shown in FIG. 60, the entire bill 50 enters inside the second duct 1202 . After that, the bills 50 are captured by the carrier 110 inside the second duct 1202 and conveyed to the bill storage chamber 14 (see FIG. 36).

When a bill sensor (not shown) detects that a bill 50 has entered the second duct 1202, the bill sensor sends a detection signal to the central controller. Upon receiving this detection signal, the central control device rotates the first roller 420A and the second roller 420B of the banknote shaping roller 420 in the forward rotation direction S1 (see FIG. 47). As a result, as shown in FIG. 61, the second roller 410B of the transport roller 410 rotates together with the connecting member 440 and is separated from the first roller 420A (the state shown in FIG. 47).
After that, as shown in FIG. 62, the second roller 410B of the transport roller 410 is maintained in a state separated from the first roller 410A. Thus, the banknote shaping device 400 returns to the state before receiving the banknote 50 (the state shown in FIG. 54).

When a plurality of carriers 110 are stored in the carrier storage duct 130, a sensor (not shown) that detects this sends a detection signal to the central controller. Upon receiving this detection signal, the central controller operates the second blower 12b (see FIG. 37(B)). As a result, the plurality of carriers 110 housed in the carrier housing duct 130 receive the wind pressure of the air flow (wind) generated by the second blower 12b, and the inside of the first duct 1201 is moved by the first blower 12a. sent back towards
Inside the second duct 1202 , an air flow W for sending the carrier 110 flows toward the banknote storage chamber 14 . Part of this airflow W may enter the banknote passage 430 and flow backward through the second banknote passage 430 .

Even in such a case, similarly to the shielding plate 510 in the first embodiment, as shown in FIG. 63, the shielding plate 560 is moved to the first position (the position shown in FIG. ) to the second position (the position shown in FIG. 53 ) to prevent the reverse air flow from entering the banknote passage 430 .
The shielding plate 560 moved to the second position is pushed by the next conveyed banknote and returns to the first position.
64 is a front view showing a state in which the banknote 50 is sandwiched between the pair of banknote shaping rollers 420, and FIG. 65 is a perspective view showing the state before and after the banknote 50 passes through the pair of banknote shaping rollers 420. FIG. be.
The pair of banknote shaping rollers 420 has the same function as the pair of banknote shaping rollers 220 in the first embodiment. Specifically, as shown in FIGS. 26 to 29, the curved or bent banknotes 50 pass through a pair of banknote shaping rollers 420, thereby eliminating the curving and bending of the banknotes 50, and It is in a substantially straight state to the extent that it does not interfere with running inside the second duct 1202 .

The above-described operation is one cycle operation in which the banknote 50 inserted into the banknote insertion device 21 is fed from the first duct 1201 to the second duct 1202 via the banknote shaping device 400 . After that, this operation is repeated.
The sheet conveying apparatus 400 according to this embodiment has the same effect as the sheet conveying apparatus 100 according to the first embodiment.
The bill passage 430 is located at a position where the airflow from the second duct 1202 easily flows, so the airflow backflow prevention device 550 is particularly effective.
