Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet storage / delivery mechanism in a paper sheet depositing / dispensing machine, and more particularly, to a separating roller for preventing double feeding of paper sheets when the paper sheets are delivered. Technology.

[0002]

2. Description of the Related Art Conventionally, the applicant of the present invention has previously proposed, as a paper sheet storing / feeding mechanism in this kind of paper sheet depositing / dispensing machine, Japanese Patent Application No.
The proposal shown in 257001 was made. The paper sheet storage / feeding mechanism shown in this application conveys the paper sheets in the storage direction for taking them into the stacking section, and at the time of feeding, transports the paper sheets in the stacking section in the forward / reverse rotatable storage / feed roller. A separating roller which is provided at a position facing the storing and feeding roller and a circumferential surface of which is in contact with the storing and feeding roller, and a drive transmission mechanism section for transmitting the driving force of the driving unit to the storing and feeding roller and the separating roller, respectively. And have.

In the drive transmission mechanism constructed as described above, the drive unit drives the storage delivery roller and the separation roller to rotate in the paper sheet storage direction during storage, and when the paper is delivered, they are rotated. The storage feeding roller and the separation roller are rotated in the paper sheet feeding direction, and the driving force is transmitted to the separation roller based on the difference between the torque of the storage feeding roller at the time of feeding and the torque of the separation roller. I am trying to switch the route. That is, the drive transmission mechanism section is provided with a drive switching means (torque limiter) inside thereof, and by this drive switching means, at the time of normal feeding, these storage feeding roller and separation roller are fed out. However, at this time, two sheets of paper are sandwiched between the storing and feeding roller and the separating roller, and a difference occurs in torque between the storing and feeding roller and the separating roller. When the torque difference exceeds a certain value, the transmission path of the driving force from the drive unit to the separation roller is cut off, and the other transmission path for transmitting the driving force in the opposite direction is connected, whereby the separation roller is connected. Is rotated in the storage direction which is the opposite direction, and one sheet of the double-fed paper sheets is returned to the stacking section.

[0004]

By the way, in the storage / feeding mechanism of the paper sheet depositing / dispensing machine configured as described above, for example, the interval between the feeding / storing roller and the separating roller is not properly determined. As a result, the frictional force between the delivery storage roller and the separation roller may be reduced, which causes a torque difference of a certain value or more between the delivery storage roller and the separation roller during delivery, and the drive switching means
The drive force transmission path from the drive mechanism to the separation roller may be switched, and the separation roller may be rotated in the opposite direction even if the double feed is not performed.
There has been a problem that the paper sheets in the stacking unit cannot be smoothly delivered by the storage and delivery roller.

On the other hand, when the distance between the feeding storage roller and the separation roller is not properly determined, and the frictional force between the feeding storage roller and the separation roller becomes larger than necessary, the fed paper is fed. Even if the leaves are double-fed, the frictional force between the double-fed paper sheets sandwiched between the feeding storage roller and the separation roller is large, and the separation roller rotates with the rotation of the storage feeding roller. There is a problem that these double-fed paper sheets are delivered as they are. Further, even if the feeding storage roller and the separation roller are set to have an optimum interval, if ink of paper sheets adheres to the peripheral surfaces of the feeding storage roller and the separation roller during repeated storage / feeding operations, The frictional force between the rollers becomes small, and as described above, the separating roller is rotated in the take-in direction even if the double feeding is not performed at the time of feeding, so that the sheet is not smoothly fed by the feeding storage roller. The problem arises.

The present invention has been made in view of the above circumstances, and eliminates the drive switching means (torque limiter) that determines the rotation direction of the separation roller based on the torque difference between the feeding storage roller and the separation roller. It is possible to reliably prevent double feeding of paper sheets by the new mechanism, and also sufficiently deal with troubles when ink of paper sheets adheres to the peripheral surfaces of the feeding storage roller and the separation roller. An object of the present invention is to provide a paper sheet storage / delivery mechanism in a paper sheet depositing / dispensing machine.

[0007]

In order to achieve the above object, according to the present invention, a storage / delivery roller for delivering the paper sheets accumulated in the accumulating section, and a storage / delivery roller are provided so as to face the storage / delivery roller. When the paper fed by the feeding roller is double-fed, the driving force of the driving unit is transmitted to each of the separation roller that returns one sheet of the paper to the stacking unit, the storage feeding roller and the separation roller. A paper sheet storage / delivery mechanism in a paper sheet depositing / dispensing machine having a drive transmission mechanism section,
In the drive transmission mechanism section, a drive force transmission path for transmitting the drive force of the drive section to the separation roller is connected or disconnected, an electromagnetic clutch means that can be set to either disconnection, and a separation roller in the sheet storage direction. A one-way clutch means for permitting rotation and restricting rotation of the separating roller in the sheet feeding direction, and a driving force transmission path for transmitting the driving force of the driving unit to the separating roller when the sheet is stored. And a control unit for setting the connection state and setting the driving force transmission path to the disconnection state at the time of feeding the paper sheets.

[0008]

According to the present invention, as the drive transmission mechanism portion, the electromagnetic clutch means which can be set to either connect or disconnect the drive force transmission path for transmitting the drive force of the drive portion to the separating roller, and the sheet of the separating roller. A one-way clutch means for permitting rotation in the paper accommodating direction and restricting rotation of the separating roller in the paper sheet feeding direction, and transmitting the driving force of the driving unit to the separating roller when the paper sheets are stored. A control unit that sets the driving force transmission path to the connected state and sets the driving force transmission path to the disconnected state when feeding the paper sheets is provided. By means of the means and the one-way clutch means, the separating roller is rotated in the direction in which the paper sheets are stored.

On the other hand, at the time of feeding the sheets, the electromagnetic clutch is controlled so that the driving force of the drive unit is not transmitted to the separating roller, and the one-way clutch means rotates the separating roller in the sheet feeding direction. Is regulated, the separating roller is held in a stopped state when the storage feeding roller feeds the paper sheet, and is not driven by the storage feeding roller rotating in the feeding direction. As a result, friction is generated between the paper sheets delivered by the storage delivery roller and the separation roller. Therefore, when the paper sheets are delivered in double, The sheet is separated by the separating roller, and the remaining one sheet is unwound by the storage / unwinding roller. That is, the paper sheet storing and feeding mechanism shown in the present invention uses the torque limiter as in the conventional case,
Since the rotation direction of the separation roller is not determined based on the torque difference between the delivery storage roller and the separation roller, the separation roller is not affected by the position setting of the delivery storage roller and the separation roller during sheet feeding. Can be reliably driven to prevent double feeding of paper sheets, and even if ink of paper sheets adheres to these rollers, as long as it is a slight stain, the separation roller A constant frictional force can be constantly applied to the paper sheets.

Therefore, when the banknotes are stored, as shown in FIG. 7, the storage / delivery roller 16 rotates clockwise as the banknote take-in direction and the separation roller 18 rotates counterclockwise as the banknote take-in direction. The deposited banknotes sent to the transport path 10 are guided to the storage / delivery roller 16 and the separation roller 18 and transported to the stacking unit 20.

(3) Since the rotational force of the gear 28 is transmitted to the shaft 34 by the operation of the one-way clutch 203 and the electromagnetic clutch 33 as described above, the impeller 24 also has the same direction as the separating roller 18. , That is, FIG.
At this time, the banknotes that are rotated counterclockwise and are sent into the stacking unit 20 through the transport path 10 are
It is tapped downward by 4 and the deposit banknotes are correctly stacked on the elevator part 21 in the stacking part 20. In addition, at the same time when the deposit banknotes are accumulated on the elevator part 21 of the accumulating part 20, the elevator drive part and the sensor means (not shown) cause the elevator part 21 to gradually descend, whereby the elevator part 21 is moved to the elevator part 21. The interval between the stacked banknotes placed and the top plate of the stacking unit 20 is always kept constant.

<< B >> Banknote payout process First, the elevator drive unit and sensor means (not shown) are placed on the upper surface on condition that a banknote payout instruction is output from the operation unit 201 (FIG. 9). The elevator section 21 is raised until the collected banknotes and the kicking roller 22 located above the stacking section 20 come into contact with each other (see FIG. 7).
Drive the solenoid (not shown) to drive the impeller 24.
Are arranged at positions spaced apart from the stacking unit 20 (see the alternate long and short dash line in FIG. 5). Further, the electromagnetic clutch 33 (FIG. 2) is turned off so that the driving force of the drive unit 202 is not transmitted to the impeller 24 and the separation roller 18 based on the bill feeding instruction output from the operation unit 201.

After the completion of the above-mentioned preparatory operation for the bill feeding process, the following processes (1) to (3) are performed. (1) The drive unit 202 drives the gear 26 shown in FIGS. 2 and 3 counterclockwise as viewed from FIG. 4 to move the shaft 25 and the storing / feeding rollers 16 and 16a fixed thereto to the shaft shown in FIG. Rotate it counterclockwise as shown in,
The kicking roller 22 that is interlocked with the shaft 25 is also rotated in the same direction, and thereby the accumulated banknotes in the accumulating unit 20 are fed out from the upper surface side to the conveying path 10 one by one.

(2) When the gear 28 fixed to the shaft 25 is rotated counterclockwise as shown in FIG. 4, the rotational force of the gear 28 is the gears 30A and 30B and the gear 31B.
・ Because it is transmitted to the gear 32 via 31C and the electromagnetic clutch 33 is turned off at this time,
The rotational force of the gear 28 only rotates the gear 32 and is not transmitted to the shaft 34. On the other hand, the storage / delivery roller 16
When the 16a is rotated counterclockwise as shown in FIG. 8, the separating roller 18 facing the rollers 16 and 16a receives a rotational force in the clockwise direction via the bill. When the shaft 3 is interlocked with the separation roller 18
In No. 4, rotation in the same direction is restricted by the one-way clutch 203, and as a result, the separation roller 18 is held at the stopped position.
And friction occurs between the dispensed bills and the dispensed bills. As a result, for example, when a dispensed bill is double-fed,
The pay-out of one dispensed bill is restricted by the separating roller 18, and the remaining dispensed bill is conveyed to the conveying path 100 through the conveying path 10 by the storing / delivering rollers 16 and 16a.

(3) Further, as described above, the transmission of the rotational force of the gear 28 to the shaft 34 is restricted by the operation of the one-way clutch 203 and the electromagnetic clutch 33, so that the impeller 24 is also stopped. Will be retained. In addition, at the same time when the deposit banknotes are paid out from the elevator part 21 of the stacking part 20, the elevator drive part and the sensor means (not shown) gradually raise the elevator part 21 and thereby place it on the elevator part 21. The accumulated banknotes are always brought into contact with the kicking roller 22 with a constant pressure.

As described in detail above, in the bill depositing / dispensing machine according to the present embodiment, the electromagnetic clutch 33 that can be set to either the state in which the driving force of the driving unit 202 is transmitted to the separation roller 18 or the state in which it is not transmitted. , A one-way clutch 20 that allows the separation roller 18 to rotate in the banknote storage direction and restricts the rotation of the separation roller 18 in the banknote feeding direction.
3 and the driving force transmission path for transmitting the driving force of the driving unit 202 to the separation roller 18 at the time of storing the bill, the connection state is set to the driving force transmission path of the driving unit 202 at the time of feeding the bill. Since the control unit 200 for setting the disconnection state in which the driving force is not transmitted to the separation roller 18 is provided, when the banknotes are stored, the separation roller 18 stores the banknotes by the electromagnetic clutch 33 and the one-way clutch 203. Will be rotated in the direction
This allows the banknotes to be smoothly stored in the stacking unit 20.

On the other hand, at the time of feeding the bill, the electromagnetic clutch 33 is controlled so that the driving force of the driving unit is not transmitted to the separating roller 18, and the one-way clutch 203 rotates the separating roller 18 in the bill feeding direction. Since it is regulated, the separating roller 18 is held in a stopped state at the time of feeding the bill by the storing and feeding roller, and is not driven by the storing and feeding rollers 16 and 16a. Banknotes delivered by the storage / delivery rollers 16 and 16a and the separation roller 1
Therefore, friction occurs between the banknote 8 and the banknote 8. Therefore, when the banknote is doubled, one banknote is separated by the separation roller 18 and only one banknote is paid out. . That is, in the above-described bill depositing / dispensing machine, a torque limiter is used as in the prior art to determine the rotation direction of the separating roller 18 based on the torque difference between the feeding storage roller and the separating roller 18. It is possible to reliably drive the separation roller 18 and prevent double feeding of banknotes without being influenced by the position settings of the feeding and accommodating roller and the separation roller 18, and even if the ink of the banknote or the like is temporarily transferred to these rollers. As long as it is a slight stain, the separating roller 18 can exert a constant frictional force on the banknotes even in the case where the adhered sheets are attached, and also in this respect, double feeding of the banknotes can be reliably prevented. It will be possible.

In the above embodiment, the gear 26, the shaft 25, the gear 28, the gears 30A and 30B, the gear 31B and 3 are used.
1C, gear 32, shaft 34, gear 43, gear 42, shaft 39
The "drive transmission mechanism section" in the claims is constituted by the above. Further, in the above-described embodiment, the paper money is a bill, but the invention is not limited to this and may be a lottery ticket, a bond, or a security.

It is possible to smooth storage of the paper sheet for.

On the other hand, when the paper is fed, the electromagnetic clutch is controlled so that the driving force of the drive unit is not transmitted to the separating roller, and the one-way clutch means rotates the separating roller in the paper feeding direction. Is regulated, the separating roller is held in a stopped state when the storage feeding roller feeds the paper sheet, and is not driven by the storage feeding roller rotating in the feeding direction. As a result, friction is generated between the paper sheets delivered by the storage delivery roller and the separation roller. Therefore, when the paper sheets are delivered in double, The sheets are separated by the separation roller, and only one sheet is fed out. That is, the paper sheet storing and feeding mechanism shown in the present invention does not use the torque limiter as in the conventional case, and does not determine the rotation direction of the separating roller based on the torque difference between the feeding storing roller and the separating roller. At the time of feeding the paper sheets, the separating roller can be reliably driven to prevent double feeding of the paper sheets without being influenced by the position setting of the feeding storage roller and the separating roller. Even if ink or the like on the paper sheet adheres to the roller, the separation roller can always apply a constant frictional force to the paper sheet as long as it is a slight stain. It is possible to reliably prevent double feeding of a class.
