Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet separating / ejecting device for separating and ejecting paper sheets such as paper money such as banknotes, securities and tickets one by one from an accommodating portion for accommodating them in a stacked manner. .

[0002]

2. Description of the Related Art An automatic vending machine or the like has a built-in conveying device for discriminating a type (amount of money, etc.) of a bill inserted in a bill insertion slot and conveying the bill to a different storage portion for each type. In many cases, it is necessary to discharge the change for the inserted amount of banknotes, so if this change includes banknotes, calculate the banknote of the denomination stored in the storage section and return it to the outlet. It is also necessary to set (that is, discharge).

When the banknotes are discharged from the storage section, conventionally, the banknotes are separated and discharged one by one by a separating and discharging device as shown in FIGS. In these drawings, reference numeral 1 is a storage box that stores banknotes 2. The banknotes 2 are stacked on a horizontal holding plate 3. The holding plate 3 is pushed upward by the coil springs 4 and 4.

A pair of ejection rollers 5 and 5 are provided above the storage box 1. Friction materials 5A and 5A made of rubber are fixed to part of the outer circumferences of the ejection rollers 5 and 5. When the ejection rollers 5 and 5 rotate clockwise in FIGS. 12 and 13 and the friction members 5A and 5A come into contact with the upper surface of the banknote 2, the uppermost banknote 2 is moved to the uppermost banknote 2 by the friction members 5A and 5A. Is sent to the left.

The storage box 1 is provided with gate rollers 6 and 6 for separating the banknotes 2 thus sent out by the ejection rollers 5 and 5 one by one and discharging them. Each gate roller 6 is formed by a pair of upper and lower feed rollers 6A and a reversing roller 6B. The upper feed roller 6A is rotationally driven in the clockwise direction in the figure, that is, in the discharging direction of the bill 2.
The lower reversing roller 6B has a built-in one-way clutch,
Can be rotated only in the returning direction (clockwise in the figure).

Therefore, when the bill 2 is carried into the storage box 1 from between the rollers 6A and 6B of the gate rollers 6 and 6,
The upper feed roller 6A is rotationally driven counterclockwise,
The lower reverse roller 6B contacts the upper feed roller 6A and rotates in the clockwise direction (arrow direction). At this time,
Due to the action of the one-way clutch of the reverse rotation roller 6B, the reverse rotation roller 6B idles on its support shaft.

When the banknote 2 is ejected, the ejection rollers 5 and 5 are synchronously synchronized with each other in a clockwise direction at a predetermined angle (for example, one rotation).
It rotates and sends the uppermost banknote 2 to the gate roller 6.
At this time, due to the friction between the banknotes 2, the banknote 2 on the uppermost layer and the banknote 2 below the banknote 2 move in the same direction. FIG. 12 shows this state.

When the uppermost layer and several banknotes 2 below it enter between the feed roller 6A and the reverse roller 6B, only the uppermost banknote 2 is sent by the feed roller 6A in the discharging direction, and the banknote 2 below it. Is blocked by the reverse roller 6B. As a result, the banknotes 2 are separated one by one by the gate roller 6 and discharged.

[0009]

[Problems to be Solved by the Invention] As shown in FIG.
When a large number of banknotes 2 are stored, the topmost banknote 2
Can be discharged smoothly. However, the number of seats will decrease,
For example, it has been found that when the number of banknotes becomes one, the banknotes 2 may not be discharged smoothly.

FIG. 13 is a diagram for explaining the operation of this defective discharge. When the number of banknotes 2 stored is one, there is a possibility that the leading edge of the banknotes 2 sent in the direction of the gate roller 6 by the ejection roller 5 is bent downward and does not properly enter between the gate rollers 6. . This phenomenon is caused by the paper money 2 in the gap 7 formed between the storage box 1 and the pressing plate 3 near the gate roller 6.
Occurs due to In the state of FIG. 12, since a large number of banknotes 2 are stacked, no more than two banknotes 2 support the topmost banknote 2 between the topmost banknote 2 and the gap 7. Therefore, it is considered that such a phenomenon does not occur.

The present invention has been made in view of the above circumstances, and a phenomenon as shown in FIG. 13, that is, the paper sheet is pressed against the gate roller at the time of discharging the paper sheet whose remaining number of sheets in the storage section is small. An object of the present invention is to provide a paper sheet separating / discharging device that prevents a phenomenon of bending with a plate from occurring and enables smooth discharging.

[0012]

According to the present invention, an object of the present invention is to feed paper sheets of the same size, which are stacked and stored in a storage portion, to a gate roller by means of an ejecting roller, and the paper sheets are fed by the gate roller into one sheet. In a paper sheet separating and ejecting device that separates and discharges sheets one by one, a holding plate that presses a stack of the paper sheets against an ejection roller, and the paper sheet that is sandwiched between the holding plate and the stack. A guide plate having at least approximately the same length as the class, and the coefficient of friction between the guide plate and the paper sheets is made larger than the coefficient of friction between the guide plate and the holding plate. And a paper sheet separating and discharging device.

Here, the paper sheets are securities such as banknotes and checks, tickets, and the like. The push-out roller may contact the upper surface of the stack from above the storage portion, and the pressing plate may be configured to push the stack up by a spring. Conversely, the push-out roller may contact the lower surface of the laminated body from below the storage unit, and the holding plate placed on the upper surface of the laminated body may push down the laminated body by the weight. In this case, the weight may be the weight of the holding plate itself.

The holding plate and the guide plate may be provided with windows communicating with each other in the stacking direction of the stack, and the presence or absence of the paper sheet may be detected by a sensor through these windows. The sensor may be, for example, a photosensor that detects light passing through these windows.

The 1,000 yen / 5,000 yen payout unit 38 is shown in FIG.
As shown in FIG. 2, the 5000 yen bills are pushed down one by one into the storage unit 26 and stored, and taken out one by one from the top and guided to the transport unit 30, while the storage unit 28 is pressed from below. Thousands of yen bills are pushed up one by one and housed
The sheets are taken out from the bottom one by one and guided to the transport unit 30. The banknotes 20 for discharge pass through the flappers 34, 36, 40 and are temporarily stored in the temporary storage / discharge unit 32, and when all the banknotes 20 to be changed remain here, they are collectively discharged to the discharge port 18. That is, the pressing roller 32 is provided on the upper surface of the bill 20 guided here.
A is provided so as to be able to move up and down, and the pressing roller 32A normally takes in a banknote in the raised position, and when a predetermined type and a predetermined number of banknotes to be changed are accumulated, the pressing roller 32A descends to press the banknote 20 from above. , A plurality of banknotes 20 are collectively discharged.

Note that the bill 20 guided from the 1,000-yen / 5,000-yen payout section 38 to the transport section 30 has the double feed detection sensors 42, 42.
Whether or not a multifeed is detected is detected. That is, it is detected whether or not two or more banknotes 20 are sent while being overlapped. When it is determined that the paper has been double-fed, the flapper 40 uses the bill 2
0 is prevented from entering the temporary holding / discharging section 32, and another flapper 44 on the downstream side thereof is rotated to guide the banknote 20 to the reject section 46.

A banknote detection sensor 48 for detecting passage of the banknote 20 is attached to the transport section 30 at an appropriate position.
The bill detection sensor 48 and the double feed detection sensor 42 are of an optical type, and are composed of a light emitting element and a light receiving element that face each other across the passage of the bill 20. Transport section 3
Storage unit 24 for 0 to 10,000 yen bills, and temporary storage / discharge unit 32
And the blades 5 having elasticity on the rotation shafts 50, 52, 54 of the discharge ports for discharging the banknotes 20 to the reject unit 46, respectively.
0A, 52A, 54A are attached (FIG. 2). These blades 50A, 52A, 54A press the banknote 20 discharged from the transport unit 30 from above and prevent the banknote 20 from floating.

Next, a part of the transport section 30 will be described with reference to FIG. FIG. 4 shows a portion for guiding the stacked banknotes 20 from the transport unit 30 to the reject unit 46. The banknote 20 returned from the 1,000-yen / 5,000-yen payout unit 38 to the transport unit 30 is sandwiched between the long belt 56 in the vertical direction shown in FIGS. As shown in FIG. 4, the belt 62 wound around the rotary shaft 54 and the rotary shaft 60 is in contact with the long belt 56. A belt 68 wound around a rotary shaft 64 and a rotary shaft 66 that movably supports the flapper 44 is in contact with the belt 62 from above. A one-way clutch is incorporated in the rotating shaft 54.

The running directions of the belts 56, 62 and 68 change in both directions. That is, when the bill 20 is stored and conveyed, the belt 56 travels downward and the belt 62 runs counterclockwise in FIG.
6 travels upward and the belt 62 travels clockwise. Therefore, the rotating shaft 60 rotates forward and backward corresponding to the conveyance direction of the bill 20.

Next, the 1,000-yen and 5,000-yen payout section 38 and the storage sections 28 and 26, which are the bill separating and discharging apparatus according to the present invention, will be described. In this embodiment, the 1,000-yen and 5,000-yen payout section 38 takes in the banknotes 20 of 1,000-yen and 5,000-yen, and separately stores them in the storage sections 28 and 26.
The banknotes 20 are separated from 26 and discharged one by one.

The payout unit 38 is constructed in substantially the same manner as the device described with reference to FIGS. As shown in FIG. 5, a pair of ejection rollers 105, 105 having friction members 105A, 105A, a gate roller 106 for the lower storage section 26, and a gate roller 1 for the upper storage section 28.
16 and. The gate roller 106 is composed of a feed roller 106A and a reverse rotation roller 106B. The gate roller 116 is formed of a feed roller 116A and a reverse rotation roller 116B.

As shown in FIG. 6, the feed rollers 106A and 116A and the reverse rollers 106B and 116B are alternately meshed in the axial direction with a gap between them, and when the bill 20 is passed through this gap, the bill 20 is corrugated. And the belts 106C and 106D at both ends,
It is a pulley around which 116C and 116D (see FIG. 2) are wound. This figure shows the gate roller 1 in FIG.
It is the figure which looked at 06 and 116 from the left side.

The reason why the bill 20 is corrugated in the gap between the rollers 106A and 106B and the gap between the rollers 116A and 116B is to facilitate separation of the bill 20 and prevent double feeding thereof. The central portions of the reverse rollers 106B and 116B can be rotated only in one direction by the one-way clutch as described with reference to FIGS. The pulleys at both ends are rotatable in both directions with respect to the shaft.

A holding plate 103 is horizontally supported by coil springs 104, 104 on the bottom surface of the storage portion 26 of the banknote 20 of 5,000 yen. On the upper surface of the holding plate 103, a guide plate 20 whose length and width are almost the same as those of the banknote 20 of 5,000 yen.
0 is placed on this guide plate 200
0 stacks L ₁ are loaded.

Above the stack L ₁ , a bill holding arm 202, which is engageable with both widthwise edges of the stack 202 outside the roll-out roller 105, is attached so as to be vertically movable. There is. The bill pressing arm 202 is located above the lower edge of the ejection roller 105 in the raised position shown in FIGS. Therefore, the upper surface of the laminated body L ₁ pushed up by the coil spring 104 comes into contact with the protruding roller 202.

A die 204 that is long in the length direction of the bill 20 is attached to the inside of the bill pressing arm 202 in the width direction so as to prevent the bill 20 from waviness. The die 204 is provided between the two divided roll-out rollers 105 and on both outer sides in the width direction, and is divided into a total of three dies.

When the bill holding arm 202 descends, as shown in FIG. 8, this arm 202 engages with both edges in the width direction of the laminated body L ₁ from above, and the laminated body L ₁ is compressed while compressing the spring 104. Push down. In this state, the laminated body L ₁ is separated from the ejection roller 105, and the banknote 20 sent by the transport unit 30 and the gate roller 106 enters the gap between the laminated body L ₁ and the ejection roller 105. 8 and 9
Indicates this state. At this time, the feed roller 10
6A rotates counterclockwise.

After ejecting the bill 20 after the bill 20 is thus taken into the storage section 26, the bill holding arm 20
2 rises. 7 and 10 show this state. While the bill holding arm 202 is rising, the bills 20 located on the upper surface of the stack L ₁ , that is, the bills 20 taken in the state shown in FIGS. 8 and 9 are pressed against the ejection roller 105.
When the bill holding arm 202 further rises, this arm 2
02 is the laminated body L pressed by the ejection roller 105
While handling both edges of the uppermost banknote 20 of ₁ with the die 204, the banknote 20 is moved upward. Therefore, when the ejection roller 105 rotates in the clockwise direction in this state, the banknotes 20 located in the uppermost layer of the stack L ₁ can be discharged one by one.

In this embodiment, the guide plate 200 is placed on the pressing plate 103. This guide plate 200 has a coefficient of friction (μ ₁ ) between the stacked body L _{1 and} the banknote 20.
However, it is important to set the friction coefficient larger than the friction coefficient (μ ₂ ) between the guide plate 200 and the pressing plate 103.

For example, it is conceivable to apply a resin having a small friction coefficient or attach a film to the lower surface of the guide plate 200. A resin having a large friction coefficient may be applied or a film may be attached to the upper surface of the guide plate 200. Fine grooves or protrusions may be provided on the upper surface of the guide plate 200 to substantially increase the coefficient of friction by utilizing physical or mechanical engagement with the bill 20.

By setting the friction coefficients of the upper and lower surfaces of the guide plate 200 in this manner, when the lowermost banknote 20 (the banknote 20 in contact with the guide plate 200) of the stack L ₁ is discharged together with the banknote 20. The guide plate 200 can be moved to the gate roller 106 side. The guide plate 200 is provided at the tip of the lowermost banknote 20 (gate roller 106).
Side edge) is prevented from bending as described in FIG. Therefore, it is possible to prevent the leading end of the bill 20 from being bent and preventing smooth discharge.

As shown in FIG. 5, the holding plate 103 and the guide plate 200 are provided with windows 206 and 208 penetrating in the laminating direction (thickness direction) of the laminated body L _1.
It is preferable that the presence or absence of the banknotes 20 stored in the storage section 26 can be confirmed through 6, 208. For example, the light emitted from the light emitting element 210 from below may be passed through the windows 206 and 208, and the light passing through the windows 206 and 208 may be detected by the photosensor 212.

The payout device 38 in this embodiment is
The storage section 26 below the storage section 26 stores and discharges the 5000-yen bill, and the storage section 28 above the storage section 28 stores and detects the 1000-yen bill. In FIGS. 5, 7, and 8, L ₂ indicates a stack of 1,000-yen bills. This mechanism is constructed almost vertically symmetrical to the mechanism of the storage section 26 of the 5000-yen bill described above. Therefore, the description will not be repeated by giving the same reference numerals to the corresponding portions of storage portion 26. The difference between the two is that the holding plate 103 is pushed up by the coil spring 104 in the storage portion 26, while the holding plate 103 is pushed down by the weight 214 placed thereon in the storage portion 28.

In the storage section 28, the guide plate 20
When ejecting the last remaining bill (thousand-yen bill) 20 that contacts 0, the guide plate 200 moves to the gate roller 116 side together with the bill 20. Therefore, the guide plate 200 prevents the leading end of the bill 20 from bending upward.

Generally, when ejecting one banknote 20,
The tip easily hits the gate roller 116 or the case around it and is easily bent. The folding direction changes depending on the creases and wrinkles on the bill 20 itself. Therefore, the tip of the bill 20 may be bent not only toward the holding plate 103 side as shown in FIG. 13 but also toward the opposite side. The guide plate 200 provided in the storage portion 28 is such a holding plate 1
It has a function to prevent bending of 03 to the opposite side (upward).

[0040]

[Other Embodiments] FIG. 11 is a view showing another embodiment. In this embodiment, by interposing a roller 216 between the guide plate 200 and the pressing plate 103, the guide plate 2
The friction coefficient between 00 and the holding plate 103 is substantially reduced.

According to this embodiment, the guide plate 200 is more easily moved together with the bill 20 and the operation is stable against changes in use conditions (humidity, temperature, dirt, etc.). Here, the roller 216 may be rotatably held on the guide plate 200 or the pressing plate 103, or may be one that holds the plurality of rollers 216 via a spacer that holds a constant gap between them. .

[0042]

According to the present invention, the stacked sheets of paper are sent to the gate roller while being pressed against the ejection roller by the pressing plate, and the uppermost ejection roller is separated by the gate roller one by one. When only one sheet that comes into contact with the sheet is discharged, a guide plate having at least almost the same length as the paper sheet is interposed between the holding plate and the stack, and friction between the guide plate and the paper sheet is generated. Since the coefficient is set to be larger than the friction coefficient between the guide plate and the pressing plate, when the last few remaining sheets (for example, one sheet) are discharged, the guide plate is used together with the sheets. Will be sent to the guide roller,
The guide plate can prevent the leading end of the paper sheet from being bent. Therefore, the sheets can be smoothly discharged up to the last sheet. .
