DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bill storing and feeding device, and more particularly to a winding type in which when a tape is wound on a roll, the bill is wound and stored together, and the tape is unwound from the roll to feed the bill. The present invention relates to a bill storing and feeding device.

[0002]

2. Description of the Related Art Conventionally, there is provided a winding roll for winding only a tape, and a winding roll for winding a tape and a bill together with a bill sandwiched between the tapes. Is performed, there is a roll-up type banknote storage and feeding device for storing and feeding banknotes. The present applicant has also proposed a banknote storage and feeding device as Japanese Patent Application No. 6-206646.

This device has a first winding roll for winding only the tape, and a second winding roll for winding the tape and the bill together with the bill sandwiched between the tapes. A winding type banknote storage and feeding device for storing or feeding out a banknote by winding and rewinding a tape between the rolls, wherein a speed-up transmission means for speeding up and transmitting a rotational drive; A torque limiter that gives a rotational resistance of
By combining with a one-way clutch that allows rotation only in one direction, tension is always generated in the tape even by forward / reverse rotation drive by one drive means, and favorable winding and rewinding of banknotes is performed. It is like that.

[0004] Further, the counting of the number of bills stored in the bill storing and feeding device is performed by providing a photosensor at an entrance portion of the device through which the bill passes, and each time the bill shields the optical path of the photosensor. The number of stored sheets is detected.

[0005]

However, in the above-mentioned bill storing and feeding device, the number of stored bills is counted by detecting that the bill has passed through the entrance portion. If the point just passed the optical axis of the photosensor, the banknote is counted twice even though one banknote is stored, and it is incorrectly counted that two banknotes are stored, or the stored banknotes. However, if there is no gap between the front and back bills due to a trouble during conveyance, the light is shielded only once even though two bills have passed, and there is a possibility that one bill is counted.

When such a situation occurs, the number of stored banknotes differs from the detected number of stored banknotes, and it is necessary to return all stored banknotes once and then check them again. become.

[0007] On the other hand, bills to be dispensed are also detected by detecting the passed bills with a photo sensor in the same manner as when the bills are stored. In addition, similarly, if the photo sensor detects and returns only the banknote stored this time, the detection becomes more uncertain, and it is practically impossible to detect and return only the banknote stored this time. there were. It is also conceivable to provide a temporary holding section immediately before the storage mechanism in the storage section to ensure that one transaction's worth of banknotes can be returned, but this requires space in the machine and increases costs. Problem arises.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 shows an example of the internal structure of a bill storing and feeding device according to the present invention. The bill has a horizontally elongated slit at a position below one side surface of a box-shaped outer casing 1 so that a bill P can be moved in and out in a longitudinal direction. The bill entrance 2 is open.

In the illustrated embodiment, two tapes T, T are used, and a bill P is inserted between the tapes T in the longitudinal direction. The width of the tapes T, T is the bill width. Approximately 1/3.

At the position near the inside of the bill entrance 2, rollers 4, 4 through which tapes T, T pass, are mounted on a substrate 3 fixed in the outer casing 1 so as to be vertically opposed to each other. On the upper and lower portions of the outer casing 1 on the opposite side, first take-up rolls 5 and 5 having flanges for the respective tapes T and T are supported on the substrate 3, respectively. 6, 6 are attached via torque limiters 7, 7 for adding tension.

At a central position between the first winding rolls 5, 5, a second winding roll 9 having an axis length corresponding to a bill width is supported by a substrate 3. It is supported by.

The tapes T, T wound on the second winding roll 8 are supplied to the rollers 4, 4 and the idlers 10, 1, respectively.
These are guided to first winding rolls 5 and 5 via 0 and 10, respectively.

A speed increasing transmission means 12 is provided in a machine room 11 partitioned by the substrate 3 inside the outer casing 1. The speed-up transmission means 12 transmits the rotation of the first or second winding roll in the rewinding direction to the other at an increased speed. Small-diameter pulleys 14 and 14 attached via first one-way clutches 13 and 13 for transmitting rotation to the first winding shafts 6 and 6 of the rolls 5 and 5 only in the direction of the dotted line, and the second winding shaft. 9 and a belt 16 wound around these pulleys 14, 14, 15.
(Timing belt) and second one-way clutches 17, 17 provided at the shaft ends of the first winding shafts 6, 6 and permitting rotation only in the direction of the dotted arrows. The pulley 15 and the small-diameter pulleys 14 constitute a speed-increasing gear. Incidentally, the diameter ratio of the pulleys 15 and 14 is set to about 3: 1.
The speed at which the first winding rolls 5 and 5 wind the tape is set to be always higher than the speed at which the second winding roll 8 unwinds the tape. That is, the speed at which the second winding roll 8 rewinds the tapes T, T is the fastest when the diameter is the maximum. Conversely, the speed at which the first winding rolls 5, 5 wind the tapes T, T is low. Since the highest speed is at the time of the minimum diameter, the second winding roll 8 sets the tape T,
It is only necessary that the speed at which the first winding rolls 5, 5 wind the tapes T, T when the first diameter is at the minimum diameter becomes faster than the speed at which the T is rewound. The rotation transmission system by the pulleys 14, 14, 15 and the belt 16 may be replaced by a gear system.

One end of the second winding shaft 9 is located outside the outer casing 1 and is connected to the pulley 1 via an electromagnetic clutch 18.
9 a belt 20 for transmitting rotation from a motor M (not shown)
Is wound.

The second winding shaft 9 is provided with a pulse generating means 21 for generating a pulse with the rotation of the second winding roll 8. In this embodiment, a rotation detecting plate 23 provided coaxially on the second winding shaft 9 and having rotation detecting slits 22, 22... 23 slits 2
It is composed of 2, 22 ... and sensor S ₁ for detecting the.

The tapes T, T are uniaxially stretched tapes, and preferably have a surface coated with silicon or the like to prevent jamming due to adhesion of an adhesive substance. In FIG. 1, S ₂ and S ₃ are sensors for detecting passage of the bill P, and are provided inside and outside the bill entrance 2.

FIG. 2 is a control block diagram. The control unit 24 has a storage unit 25 for storing the number of pulses generated by the pulse generation unit 21. When returning the stored bills for one process, the control unit 24 stores the stored banknotes in the storage unit 25. Control is performed to rotate the second winding roll 8 in the feeding direction by the number of pulses set.

The rotation detecting plate 23 of the pulse generating means 21 does not necessarily have to be provided on the second winding shaft 9 and may be rotated in synchronization with the second winding roll 8 if necessary. Alternatively, the rotation may be branched from the second winding shaft 9 to rotate the rotation detection plate 23 due to space.

Next, the operation will be described.

When the banknotes P are stored in the outer casing 1, the rotation from the motor is transmitted to the second winding shaft 9, and the second winding roll 8 is rotated in the direction of arrow a. At this time, the large-diameter pulley 15 and the rotation detection plate 23 also rotate in the same direction.

The rotation of the large-diameter pulley 15 causes the small-diameter pulleys 14, 14 to rotate via the belt 16, and the first winding shafts 6, 6 are rotated by the second one-way clutch 1.
The pulleys 14, 1 are not rotated by the action of the first one-way clutch 13, and are not rotated by the action of the first one-way clutch 13.
Only the roller 4 idles, and the first winding rolls 5, 5 are in a state where no driving force is transmitted.

The tapes T, T are formed by the second winding roll 8.
When winding up the first winding rolls 5, 5, the tapes T,
The first winding shafts 6, 6 cannot rotate clockwise due to the pulling action of T, but tension occurs on the tapes T, T, and the tension reaches a predetermined value. When the torque reaches the torque limiters 7, 7, a torque equal to or more than a predetermined value is applied, and the first winding rolls 5, 5 rotate for the first time. As a result, a tension according to the set torque of the torque limiters 7, 7 is always applied to the tapes T, T.

The bill P supplied from the bill inlet / outlet 2 is sandwiched between the tapes T, T thus wound, wound up by the second winding roll 8 and stored.

[0028] The second operation according to the number of banknotes in one storing process.
Rotation of the take-up roll 8, the number of pulses by the slit 22, 22 ... detection of the sensor S ₁ in accordance with the rotation of the rotation detecting plate 23 is stored in the storage unit 25.

When a predetermined number of banknotes have been stored and become full, a sensor (not shown) detects the end of the tapes T, T and stops further receipt.

When it is necessary to return the banknotes P for one process stored as described above due to some trouble, the second winding roll 8 rotates in the direction of the arrow to rotate the tape T, It is returned through the bill doorway 2 from the interval T. At this time, since the number of rotations of the second winding roll 8 for one process is stored in the storage unit 25 as the number of pulses, the second winding roll 8 is moved in the feeding direction by the number of pulses through the control unit 24. (In the direction of the arrow) to discharge the number of banknotes P stored in one process.

The bill is fed out by rotating the second winding shaft 9 in a counterclockwise direction via the pulley 15, the belt 16, and the pulleys 14, 14 to the first winding shafts 6, 6 via the first one-way clutch 13, 13, the rotation is accelerated and transmitted, and the first winding rolls 5, 5 are transported by the tapes T, T
The tapes T, T are to be wound at a speed higher than the speed at which the tapes T, T are unwound, so that the tapes T, T are wound without tension loosening. When the tension exceeds a predetermined value, a torque higher than the predetermined value is applied to the torque limiters 7, 7, causing slippage. As a result, the tapes T, T are always provided with tension in accordance with the set torque of the torque limiters 7, 7.

FIG. 3 is a timing chart showing a situation in which a stored bill has a problem and is returned. In this example, three thousand yen bills (3
2,000 yen) is stored, and two thousand-yen banknotes (2,000 yen) are stored in the second process. For the first 3,000 yen, the sensors S ₂ ,
Also detected correctly and S _3, during the processing of the 2nd, there is such tear thousand yen banknotes of the second sheet translucent state A takes place in the middle of the sensor S ₃ and the other of the sensor S ₂ is normally detected This indicates that an abnormality was detected due to the operation. Even in this case, the rotation amount of the second winding roll 8 is controlled by the pulse generation means 21.
Transmits the number of pulses for two thousand-yen banknotes, and the number of pulses is stored in the storage unit 25 as the second processing.

When the above situation occurs, it is necessary to return and confirm the 2,000 yen (two thousand-yen banknotes) as the second processing amount. By rotating 8 in the feeding direction by the number of pulses for the second processing, two 1,000-yen bills are returned regardless of the existence of a torn bill.

Motor (not shown but indicated by M)
Is stopped after the first storage processing, re-driven during the second storage processing, stopped after the payment processing, and then reversely driven when the second storage processing banknote is returned, until the return is completed. It stops after driving is continued.
