Embodiment Hereinafter, an embodiment of the paper sheet conveying apparatus according to the present invention will be described as a first embodiment.
FIG. 6 to FIG. 6 will be described.

As shown in FIG. 1, the bill handling device discriminates the authenticity of the bills 1 as bills inserted from the slot 11 and passes the bills, and the bills are discharged from the bill discriminating device 2. It has a bill transport device 3 as a paper sheet transport device for transporting the bills 1 along the transport path, and a bill storage device 4 for stacking and storing the bills 1 transported by the bill transport device 3.
Bill validator 2, bill transporter 3, and bill storage device 4
Are organically driven by an electronic control unit including a microcomputer (not shown). When the banknote 1 is not a true banknote, the electronic control unit rejects the receipt of the banknote 1 in the banknote discriminating device 2 and returns the banknote 1 to the insertion slot 11, and the banknote discriminating device 2 determines that the banknote 1 is a true banknote. Sometimes, various electronic controls are performed to receive the bill 1 in the bill storage device 4 via the bill transport device 3.

The bill 1 inserted from the insertion slot 11 provided at one end of the housing 10 constituting the bill discriminating apparatus 2 is determined by a known method while the bill 1 is moving in the bill discriminating apparatus 2. The detailed description of the known banknote discriminating apparatus 2 used in a wide range of fields such as a bank automatic teller machine, a vending machine, and a ticket vending machine is omitted. Further, as shown in the drawing, the bill validator 2 is provided with feed rollers 12 and 13 for sending out the bill 1 determined as a true bill to the bill transporter 3, and the bill 10 is provided at the other end of the housing 10 of the bill validator 2. One outlet 14 is provided.

A guide member 30 that extends downward from the vicinity of the outlet 14 of the bill validator 2 and that is formed in a curved shape from an elastic metal material is disposed. The guide member 30 is elastically bent by the pressing force of the bill 1 when the bill 1 sent from the outlet 14 comes into contact. As shown in FIG. 2, in order to reduce the weight and improve the flexibility of the guide member 30, a slit 30a extending in the longitudinal direction is used.
Are formed on the guide member 30. A free end portion 30b is formed at the upper end of the guide member 30, and a support end portion 30c that is pivotally supported by a fourth shaft 36b serving as a drive shaft is provided at the lower end. Support end
30c has a hole 30d through which the fourth shaft 36b is inserted, and a hole 30e into which one end of the tension spring 42 is locked. The other end of the tension spring 42 is fixed to a shaft 44 fixed to the side wall 43 of the bill transporting device 3 as shown in FIG. As shown in FIG. 1, since the tension spring 42 pulls the support end 30c of the guide member 30 upward, the guide member 30 is urged counterclockwise in FIG. 1 around the fourth shaft 36b. The free end 30b of the guide member 30 is in contact with the end wall 10a of the housing 10.

A first feed belt 31 and a second feed belt 32 are arranged adjacent to the guide member 30 in a V-shape. The first feed belt 31 is arranged along the slit 30a of the guide member 30,
The first feed belt 31 is wound between a first pulley 33a and a second pulley 33b rotatably supported at the center of a first shaft 34a and a second shaft 34b. First pulley 33a
Is the first attached near the outlet 14 of the bill validator 2.
The second pulley 33b is rotatably supported on a shaft 34a of the banknote storage device 4 and a second shaft 34b
It is supported rotatably. As shown in FIGS. 3 to 5, the respective ends of the first shaft 34a and the second shaft 34b are supported by the side wall 43 of the bill transporting device 3. The third pulley 35a is a third shaft mounted at a distance from the outlet 14 of the bill validator 2.
The fourth pulley 35b is mounted near the entrance 72 of the bill storage device 4 and rotatably supported at the center of the fourth shaft 36b serving as a drive shaft. The second feed belt 32 passes through the slit 30a of the guide member 30, and is wound between the third pulley 35a and the fourth pulley 35b. Third
Each end of the shaft 36a and the fourth shaft 36b is a side wall of the bill conveying device 3.
Supported by 43. The fourth shaft 36b is operatively connected to an output shaft 38a of a motor 38 via a transmission belt 37.

A first shaft 34a for supporting the first feed belt 31 and a third shaft 36a for supporting the second feed belt 32 are connected to the guide member 30.
Are provided separately from each other on the inside and outside. First feed belt
The second shaft 34b supporting the first feed belt 31 and the fourth shaft 36b supporting the second feed belt 32 are vertically arranged in parallel with each other, and the second pulley 33b supported by the second shaft 34b is The fourth pulley 35b is supported by the fourth shaft 36b. For this reason, the second feed belt 32 is wound around the fourth pulley 35b from the outside of the first feed belt 31 near the entrance 72 of the bill storage device 4, and is wound around the second pulley 33b and the fourth pulley 35b. The first feed belt 31 and the second feed belt wound respectively.
32 come into contact with each other so that the banknote 1 is involved. Motor 38
4, the fourth shaft 36b is rotated in the counterclockwise direction in FIG. 1, and the second feed belt 32 for driving is rotated in the counterclockwise direction. The second shaft 34b around which the first feed belt 31 that contacts the rotating second feed belt 32 is wound is rotated clockwise. In the illustrated example, the second feed belt 32 on the fourth shaft 36b is driven by the motor 38, but the first feed belt 31 can be driven by the motor 38.

As shown in FIG. 2, two arms 39 are fixed to both ends of the first shaft 34a on both side edges of the first feed belt 31 so as to project obliquely downward. Exit 14 of bill validator 2
The leading end of the banknote 1 discharged from is moved toward the guide member 30 by the arm 39 and the posture thereof is controlled so as to immediately contact the guide member 30.

A gear 40 is fixed to one end of the fourth shaft 36b, and an arm 50 is supported on one end of the fourth shaft 36b outside the gear 40.
One end 50a of the arm 50 is locked to one end of the spring 60,
At the other end 50b, which is a free end of the arm 50, an idle gear 41 screwed to the driving gear 40 is rotatably carried. The arm 50 pivotally mounted about the fourth shaft 36b is biased clockwise about the fourth shaft 36b by a spring 60 in FIG.

The bill storage device 4 for storing the bills 1 transported from the bill transport device 3 is detachable from the bill handling device from a predetermined direction indicated by an arrow X in FIGS. 1 and 2. A slit-shaped entrance extending in the lateral direction in the main body 70 of the bill storage device 4
72 are provided. Banknote 1 sent by rotation of the first feed belt 31 and the second feed belt 32 of the banknote transport device 3
Is moved from the inlet 72 to the inside of the main body 70. Inside the main body 70 close to the entrance 72, the tension roller 73 and the drive roller 74 are arranged vertically in parallel and in contact with each other. A shaft 73a that supports the tension roller 73 and the drive roller 74
And 74a are rotatably supported on both side walls of the main body 70. Tension roller 73 and drive roller from inlet 72
When the bill 1 is supplied during the period 74, the tension roller 73 and the drive roller 74 rotate so as to pinch the bill 1 and take it into the main body 70. An intermediate gear 75 is provided on the axis of the tension roller 73 outside the main body 70. When the bill storage device 4 is inserted into the bill handling device frame from one direction and pressed to a predetermined position, the intermediate gear 75 is moved to the bill transport device. It automatically meshes with the idle gear 41 on the third side. Therefore, when the bill transport device 3 is operated, the drive roller 74 and the tension roller 73 rotate relatively via the idle gear 41.

A reverse rotation prevention device (not shown) having a gear 77 screwed to the intermediate gear 75 is disposed inside the main body 70. The intermediate gear 75 meshing with the gear 77 has a tension roller 73 and the bill 1 as a main body.
It rotates in the capture direction moving into 70, but reverse rotation is prohibited. Since the reverse rotation of the tension roller 73 and the drive roller 74 is prohibited, the banknote 1 once stored in the main body 70 cannot be illegally taken out from the entrance 72. As shown in FIG. 1, a handle 71 for transporting the bill storage device 4 at the time of collection is provided in the main body 70, and the bills 1 accumulated in the bill storage device 4 are automatically counted by the electronic control device, and An alarm is issued when the number of copies is reached.

With the above configuration, the bill 1 is inserted into the bill discriminating device 2
When inserted from 11, the banknote 1 determined to be a true banknote during the movement in the banknote discriminating apparatus 2 is a feed roller 12 at the final end,
By 13, the bill is sent from the outlet 14 to the bill transport device 3. At this time, the motor 38 of the bill transport device 3 starts driving based on the detection signal generated when the bill 1 passes the predetermined position, and the first feed belt 31 and the second feed belt 32 rotate. .

The leading end of the bill 1 discharged from the bill discriminating device 2 is inserted between the first feed belt 31 and the second feed belt 32, abuts on the inside of the free end portion 30b of the guide member 30, and follows the transport path. The transport direction is changed downward. When the bill 1 comes into contact with the guide member 30, the tension force of the guide member 30 against the tension spring 42 for urging the guide member 30 in the counterclockwise direction in FIG. The free end 30b pivots clockwise outward about the fourth shaft 36b. At the same time, when the guide member 30 is elastically deformed, the pressing force against the leading end of the bill 1 increases against the rotation of the free end portion 30b, and the elastic force for changing the transport direction of the leading end of the bill 1 downward is reduced. As a result, the leading end of the bill 1 can be smoothly guided downward. In particular, since a new bill has a large resistance to deformation, when the tip of the bill 1 is changed in the downward direction, the bill 1
Moves along the guide member 30, and is smoothly transported without departing from the transport path. In addition, since the bill 1 is old and soft, the tip of the bill 1 discharged from the bill discriminating device 2 curves downward and does not come into contact with the guide member 30.
The transport direction is changed so that the leading end of the banknote 1 comes into contact with the arms 39 arranged on both side edges of the first transport belt 31 and comes into contact with the guide member 30.

Banknote 1 that has reached the lower part of the transport path along the guide member 30
Is a contact point 31a at which the second feed belt 32 wound around the fourth pulley 35b comes into contact with the outside of the first feed belt 31 wound around the second pulley 33b so as to wind the bill 1 around.
Is inserted into. The length of the bill 1 is the outlet of the bill validator 2.
It is longer than the distance from 14 to the contact point 31a. Since the distance from the outlet 14 of the bill validator 2 to the contact point 31a is actually much shorter than the length of the bill 1, the tip of the bill 1 reaches the contact point 31a and the bills are fed to the feed rollers 12, 13 of the bill validator 2. The bill validator 2 determines the authenticity of the bill while the rear end of the bill 1 is clamped. When the electronic control unit determines that the bill 1 is not a true bill, the feed rollers 12 and 13 are reversed, and the bill 1 is returned to the insertion slot 11. When the bill 1 is determined to be a true bill, the feed rollers 12 and 13 further push the bill 1 to the outside of the bill validator 2. The tip of banknote 1 is the first
The bill 1 is pushed out of the discharge port 14 while being held between the contact points 31a between the feed belt 31 and the second feed belt 32, and as shown in FIG. To bend in a bow or S-shape. At this time, the first feed belt 31 is based on a detection signal generated by the passage of the bill 1.
When the driving of the second feed belt 32 is started, the bill 1
Is forcibly extended by the pulling action of rotation of the first feed belt 31 and the second feed belt 32, and the bill storage device 4
Sent to For this reason, since the bills are not transported in a bent state as in the conventional bill handling device, jamming (clogging) or stagnation of the bills 1 in the transport path can be prevented, and the bills 1 can be transported smoothly. . A stiff banknote 1, such as a new banknote, has relatively few failures due to jamming and is sent smoothly.

As shown in FIG. 1, the bill 1 transported by the bill transport device 3 is moved from the entrance 72 to the inside of the bill storage device 4. When the rotation from the bill transporting device 3 is transmitted to the tension roller 73 and the drive roller 74, the leading end of the bill 1 is nipped between the tension roller 73 and the drive roller 74 and moved inside the main body 70. The number of banknotes 1 accumulated inside the main body 70 is automatically counted by the electronic control unit, and when the number reaches a predetermined number, an alarm is automatically generated. When taking out the banknote storage device 4 from the banknote handling device for collection, the reverse rotation of the tension roller 73 and the drive roller 74 is prohibited, so that the internal banknote 1 from the entrance 72 of the banknote storage device 4 is removed.
Can be prevented from being illegally extracted by a third party.

Therefore, the following advantages can be obtained in the embodiment of the present invention.

The bill transfer device of the present invention can be easily mounted between the existing bill discriminating device and the bill storage device, and there is no need to change the design of the entire bill handling device.

Since the bill can be held in the bill transport device until the bill discrimination device completes the authenticity judgment of the bill, the bill transport device can be used for bills having various shapes with different denominations.

When the bill is not a true bill, the feed roller of the bill discriminating device may be reversed to return the bill to the insertion slot, so that there is no need to provide a reverse rotation mechanism in the bill transport device. For this reason,
The structure of the bill transport device is extremely simplified.

In the conventional bill device, since the bill storage device is arranged at the back of the bill discriminating device, it is inconvenient to take out the bill storage device at the time of collecting money, and it is necessary to form an opening for inserting and removing the bill storage device further behind the bill handling device. did not become. According to the present invention, since the bill validator and the bill storage device can be arranged so as to be vertically stacked in two stages, both insertion of the bill and removal of the bill storage device can be performed from the front of the bill handling device.

Since the flexible guide member is transferred, the bill traveling direction can be smoothly changed without damaging the bill in the bill transport device, and the bill can be held in various curved shapes.

Further, the above embodiment of the present invention can be modified.
For example, a plurality of guide members may be provided, and a plurality of first and second feed belts may be provided. In addition, the present invention can be applied to a paper or card transport device other than a banknote.

EFFECT OF THE INVENTION The paper sheet transport device according to the present invention can smoothly transport paper sheets without jamming (clogging) or stagnation in the middle of the transport path as in the related art. Also,
Since it can be used for existing banknote discriminating devices and banknote storage devices, a wide range of applications can be secured.
