BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet processing apparatus applied as a financial device, for example.

[0002]

2. Description of the Related Art A bill processing apparatus for carrying out operations such as denomination determination, correctness determination, counting, and authenticity determination of banknotes is shown in FIG.
It is configured as shown in.

That is, the bills 9 set in the bill supply unit A are fed out one by one by the rotation of the feeding roller 1, and the discrimination unit B provided on the conveyance path 10 of the bills 9 denominates denomination, normality, front and back, Discriminate counts, etc., and then sort according to the determination result in the sorting unit C, and then the totaling unit D according to the type of money and the loss
It has a structure to be stored in.

By the way, in the bill supply section A, the bills 9 stacked and set are reliably separated one by one,
It is necessary to stably supply the banknotes 9 without causing jams (clogging), double feeding (overlapping), skew (skew), pitch unevenness (variation in pitch of conveyed banknotes), and the like.

In the conventional banknote handling apparatus, in order to separate and pay out only one banknote 9 from the stacked banknotes 9 set in the banknote supplying section A, first, the lowermost banknote 9 is rotated by rotating the feeding roller 1. The bill 9 is fed, and then the bill 9 is passed between the gate roller 3 and the take-in roller 2. At the time of this passage,
The second and subsequent banknotes 9 sent along with the bottommost banknote 9 are stopped by the gate roller 3 which is reversed or stopped, and only the banknote 9 separated into one sheet is rotated by the take-in roller 2. , And is delivered to the transport unit 10.

However, the bill 9 has a large change in mechanical characteristics such as friction coefficient, rigidity, and thickness due to the environment in which it is handled, the period, and the like, and there are differences depending on the denomination. Gate roller 3 and loading roller 2 that can be loaded
Since the gap between and is different, it was difficult to adjust and fix the gap so that good picking performance could be obtained for any banknote. Further, there are usually two gate rollers 3 on the left and right sides, and it was difficult to set the same gap between the two take-in rollers 2.

Further, even after the gap adjustment, the friction coefficient changes due to the change of the surface condition of rubber or the like, so that a plurality of banknotes 9 bite into the gap and the banknote 9 cannot be taken out, or a banknote having two or more gaps. However, there have been problems such as double feeding of paper sheets passing through, skew occurring due to a difference in the gap between the left and right gate rollers 3 and 3 and the take-in roller 2, uneven pitch in which the intervals of the taken-in bills 9 are uneven.

Therefore, a detector is provided on the conveyance path of the bill 9 and the detector measures skew, pitch, etc. of the conveyed bill, and the two gate rollers 3, 3 on the left and right sides are measured according to the conveyance information. Each move slightly, and take-in roller 2
There is provided a banknote processing device in which the gap between the banknotes and the banknotes is changed and the banknotes 9 taken out thereafter are taken in in an optimum state.

[0009]

However, the bill 9
Since the state of each banknote is different, for example, when old banknotes are stacked and set after new banknotes, even if the optimum gap is set from the transport information of the banknotes that have been transported, the old banknote that will be taken out next will be On the other hand, the gap was not optimal, and there was a high possibility of jams and double feeds.

Therefore, the present invention has been made to solve the problems such as jamming and double feeding that occur in a paper sheet processing apparatus, and provides a paper sheet processing apparatus that can stably supply banknotes. The purpose is to [Constitution of Invention]

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in FIGS. 1 and 2 show a banknote take-out section of the banknote handling machine according to the present invention. In the figure, reference numerals 11 and 11 denote feed rollers in which rubber and the like having a large friction coefficient are attached to at least the outer peripheral portion for feeding the banknotes 19 that are stacked and set. These feed rollers 11 and 11 are shafts 21
It is connected to the drive motor 12 via.

In front of the feeding rollers 11 and 11,
Intake roller 15 with rubber 15a attached to a part of the outer periphery
Is provided. A drive motor 23 is connected to the take-in rollers 15 via a shaft 22. A gate roller 14 for preventing double feeding of the bills 19 is opposed to the upper side of the take-in roller 15 with a gap.

At the front part of the take-in roller 15, conveying rollers 25, 25, and the springs 2 are attached to the conveying rollers 26, 26.
Pinch rollers 25, 25 that are urged by 7 to make rolling contact are provided. The banknotes 19 are set in a stacked state on the banknote stand 28 and are pressed against the feeding roller 11 by the load of the backup 29. On the other hand, between the gate roller 14 and the pinch roller 25, a detecting means 13 for detecting the state of the bill 19 is provided.

As will be described later on the basis of the detection information of the detecting means 13, the gate roller 14 is driven in the vertical direction to change the gap g with the take-in roller 15 to change the state amount (for example, skew, Change the pitch etc.).
As a result, the optimum gap adjustment corresponding to each bill can be performed in the bill taking operation.

By the way, as shown in FIG. 3, the gate roller 14 has a rubber attached to the surface of the one-way clutch so that it can be rotated only in the direction opposite to the conveying direction of the bills 19.

The gate roller 14 can be moved up and down by a gate roller driving mechanism 30 as a variable means. That is, the gate roller 14 is rotatably attached to one end of the lever 33 via the shaft 31, and the other end of the lever 33 is attached to the lower end of the fixed base 37 via the spring 35. Further, the fixed base 37 is provided with a piezoelectric element 36.
The lever 33 is connected to the lower end of the via a parallel leaf spring 38.

When a voltage is applied to the piezoelectric element 36,
The piezoelectric element 36 is slightly displaced in the vertical direction by a maximum of about 15 μm, and this displacement is enlarged to about 300 μm by using the enlargement mechanism based on the ratio of the distance between the parallel leaf springs 38 and the length of the lever 33 to move the gate roller 14. Let The piezoelectric element 3
Since 6 deforms in proportion to the voltage, the gap between the gate roller 14 and the take-in roller 15 can be arbitrarily set depending on the magnitude of the applied voltage. A pair of left and right gate roller drive mechanisms 30 configured as described above are attached to set a gap.

After the gate roller drive mechanism 30 is used to set the gap between the gate roller 14 and the take-in roller 15, the drive motor 12 of the feed roller 11 is rotated in the direction of the arrow by a drive circuit (not shown). As a result, the feeding roller 11 rotates and the feeding roller 11
By the frictional force between the bill 19 and the bill 19, the bill 19 is taken in by the take-in roller 1.
5 and the gate roller 14.

The lowermost bill 19 among the bills 19 conveyed is forwardly fed by the frictional force with the rubber portion of the take-in roller 15 which is larger than the frictional force of the gate roller 14,
The second and subsequent bills 19 are stopped by the frictional force of the gate roller 14, and as a result, only one bill 19 passes through the gap between the gate roller 14 and the take-in roller 15.

The carrying state of the bill 19 passing through the gap between the gate roller 14 and the take-in roller 15 is detected by the detecting means 13. Then, a voltage is applied to the voltage element 36 of the variable means 30 according to the detected state, and the voltage element 36 expands and contracts. By this expansion and contraction, the lever 33 is rotated as shown in FIGS. 4 and 5, and the gate roller 14 is moved up and down to change the gap between the gate roller 14 and the take-in roller 15. As a result, the state amount (for example, skew, pitch, etc.) of the bills 19 taken in is adjusted.

By this adjustment, the state of the bills 19 to be conveyed is optimally controlled, and the conveying rollers 2 rotating in the forward direction.
6 and the pinch roller 25, and the conveyance roller 2
The conveyance is performed by the frictional force between the bill 6 and the bill 19. The bills 19 conveyed are discriminated by the discriminating section B such as denomination, damage, etc.
According to the determination result in the distribution unit C, the denomination,
It is accumulated in the totaling unit D for each of the damages. The above operation is performed by the bill stand 2
A series of banknote processing operations are completed by repeatedly performing the banknotes 19 one by one until there are no banknotes 19 set on the table 8.

As described above, the state quantity of each banknote 19 set in the take-in section is detected by the detecting means 13 arranged between the gate roller 14 and the pinch roller 25, and based on the detected information. Since the gap amount between the gate roller 14 and the take-in roller 15 is optimally controlled, it is possible to realize a bill processing apparatus that can stably supply bills regardless of the state of the bills 19.

By the way, a photodiode 41 and an LED 42, which constitute a detecting means, are arranged on the carry-out end sides of the transport roller 26 and the pinch roller 25, and the banknote 19 taken out as described above has passed a certain time. If the photo diode 41 and the LED 42 are not blocked, the bill 19
However, it is determined that a jam has occurred between the gate roller 14 and the take-in roller 15.

When it is determined that a jam has occurred, rotation of the feed roller 11, the take-out roller 15, the pinch roller 25, etc. is stopped, and the piezoelectric element 36 of the gate roller drive mechanism 30 is stopped.
Reduce the applied voltage to.

As a result, the piezoelectric element 36 contracts, the gate roller 14 is released upward as shown in FIG. 7, the gap between the take-out roller 15 and the gate roller 14 is enlarged, and the jammed bill 19 is released. To be done. In this state,
The operator lowers the banknotes 19 set on the paper feed tray 28, and removes the banknotes 19 that have cut into the gap.
By performing the above jam clearance operation, it is possible to easily remove the jammed banknote. After removing the jam, a predetermined voltage is applied to the piezoelectric element 36 to return the gap to the optimum state, and then a normal take-out operation is performed.

As described above, when the bill 19 is clogged in the gap between the gate roller 14 and the take-out roller 15, the gate roller drive mechanism 30 enlarges the gap between the gate roller 14 and the take-out roller 15, and the operator is clogged. Since the bills 19 are taken out in a state where they can be easily taken out, the jammed bills 19 are not forcibly pulled out to break the bills 19 or make a break. As a result,
Jam in the take-out section where jamming is most likely to occur can be easily eliminated, and the operator can easily deal with jamming. The gate roller drive mechanism is not limited to the above-mentioned one embodiment,
The gate roller drive mechanism 43 may be configured as shown in FIG. That is, the pair of piezoelectric elements 45,
45 may be provided and configured.

According to this embodiment, the pair of piezoelectric elements 4
By applying different voltages to 5 and 45, the gate roller 14 can be moved in the skew direction shown by the arrow S, and the conveyance state of the banknote 19 can be controlled more accurately.

Although the above description has been made on the cash processing machine which is usually used in a financial institution such as a bank, ATM,
The same effect can be obtained in an automatic banknote handling machine such as a CD.

[0031]

As described above, according to the present invention, the gap between the take-in roller and the gate roller is adjusted according to the conveying state of the paper sheets to be taken out. Instead, it becomes possible to stably take in the paper sheets.
Further, the gate roller can be moved also in the skew direction according to the conveyed state of the paper sheets taken out, so that the paper sheets can be taken in more stably.

Further, when the paper sheet is jammed between the take-in roller and the gate roller, the gate roller is moved in the direction away from the take-in roller, so that the work for removing the jammed paper sheet is easy. It will not break the paper sheets.
