Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a paper sheet handling device, and particularly to a paper sheet handling device that separates and feeds out sheets one by one from a large number of accumulated sheets. The present invention relates to a sheet handling device suitable for stabilizing the separating and feeding operation of a paper sheet handling mechanism.

[Background of the Invention] In order to process the feeding of paper sheets, conventional paper sheet handling devices stack the taken-in paper sheets and store paper sheets for replenishing new sheets.
BOX and storage of the above-mentioned paper sheets when delivery is requested.
It has a separating and feeding mechanism that separates and feeds out the paper sheets stacked in a box one by one.

As described in Japanese Unexamined Patent Publication No. 58-130833 and Japanese Utility Model Application No. 56-148034, the separating and feeding mechanism consists of a roller that takes out the paper sheets while being pressed against the paper sheets, and a roller on both sides of the roller that takes out the paper sheets while being pressed against the paper sheets. It has a structure in which a guide plate is attached to the paper sheet for regulating the direction in which paper sheets are taken out, and the guide plate is generally fixed to a frame or the like and has a structure in which it comes into contact with the surface of the paper sheet.

In this configuration, the take-out roller is usually placed in the center of the paper sheet, so when the paper sheet receives pressure from the rotating take-out roller, the paper sheet is folded, wrinkled, etc., resulting in a concave bulge. . If the paper sheet is fed into the front delivery roller in its swollen state, the paper sheet is likely to be bent or torn, so to prevent this, guide plates are provided on both sides of the delivery roller.

However, since the concavely swollen paper sheets come into contact with the guide plate, when the paper sheets are taken out, the paper sheets are tilted due to irregular distribution of frictional resistance between the guide plate and the paper sheets. row (skew),
Jams caused by bending or tearing, similar to the above,
There were many occurrences of uneven feeding intervals of paper sheets due to irregular distribution of frictional resistance, and uneven feeding intervals of paper sheets due to unstable pressure due to dispersion of the pressure on the paper sheets of the take-out roller. Therefore, it was necessary to stabilize the pressure between the take-out roller and the paper sheets and the frictional resistance between the guide plate and the paper sheets, taking into account the concave bulges that occur in the paper sheets.

[Purpose of the invention]

The purpose of the present invention is to solve such conventional problems and prevent skews, jams, etc. in a separating and feeding mechanism that separates and feeds stacked paper sheets one by one by a simple and inexpensive method. An object of the present invention is to provide a paper sheet handling device that can prevent the above problems from occurring and stabilize the operation of a separating and feeding mechanism.

[Summary of the invention]

In order to achieve the above object, the paper sheet handling device of the present invention includes a take-out roller 2 that takes out a stack of paper sheets 11 held by a push plate 1, and a guide plate that regulates the take-out direction of the take-out roller 2. 3, 5, and means 6 for separating and feeding out the taken out paper sheets 11 one by one;
7, the paper sheet handling device has a paper sheet handling device that is attached to a spring 9, moves up and down according to the accumulated state of the paper sheets 11, and controls the feeding of the paper sheets 11 from the top surface. The independently movable guide plates 3 and 5 provided on the left and right sides with respect to the feeding direction of paper sheets 11 are brought into contact with the paper sheet 11, and the spring constant of the spring 9 is appropriately set. In order to equalize the resistance on the left and right sides of the paper sheet 11, the paper sheet 11 is characterized by having guide rollers 10a and 10b attached to each of the left and right guide plates 3 and 5, respectively.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

1 is a front view of a separating and feeding mechanism showing an embodiment of the present invention, FIG. 2 is a side sectional view of FIG. 1, and FIG. 3 is a sectional view taken along line X-XX of FIG. 2.

In FIGS. 1 to 3, 1 is a stack of banknotes 11
2 is a P roller that moves the upper banknote, 3 is a guide that supports the guide roller 10a, 4 is a guide, 5 is a guide that supports the guide roller 10b, 6 is a guide that supports the banknote 11 together with the G roller 7. 1
F rollers that feed out sheets while separating them one by one, 8a, 8b
1 is a bearing that connects the shaft 12 and the guides 3 and 5; 9 is a spring attached to the guides 3 and 5;
3 is a banknote guide.

The stacked banknotes 11 are held by a push plate 1, and are urged by a spring (not shown) to push up the P roller 2 with the upper surface of the banknotes 11.

Guides 3 and 5 on both sides of the P roller 2 connect to the shaft 12 via bearings 8a and 8b, respectively.
It has a structure that allows it to freely rotate in the direction of arrow A (the direction in which banknotes 11 are stacked). Further, it is biased toward the banknote 11 by a spring 9 attached to one end thereof.

Guide roller 10a attached to guides 3 and 5,
10b presses the upper surface of the banknote 11 with the biasing force applied to the guides 3, 5, and the guides 3, 5 and the banknote 1
Keep a constant interval between 1.

The separating and feeding mechanism rotates the P roller 2 in the direction of arrow B by a drive source (not shown), moves the upper banknote 11 in the direction of the F roller 6, and rotates the P roller 2 in the direction of the arrow B.
Similarly to the P roller 2, the G roller 7 is also driven by a drive source (not shown) in the same direction as the P roller 2, and in the same direction as the P roller 2.
P roller 2 by rotating it in the opposite direction to roller 2.
The banknotes 11 sent from the side are separated one by one and fed out to the next stage.

Next, the function of the guide rollers 10a and 10b when the P roller 2 moves the bill 11 in the direction of the F roller 6 will be described with reference to FIG.

As described above, the banknote 11 that is urged toward the P roller 2 side by the push plate 1 is folded or wrinkled into a concave shape like the banknote 11a when the P roller 2 rotates. Swell up. The guides 3 and 5 at the top of the banknote 11 apply a moderate force (approximately 100g) via guide rollers 10a and 10b.
Since the banknote 11a is pushed back, the concave bulge of the banknote 11a is corrected into a state similar to that of the banknote 11b.

The concave bulge of the banknote 11a that occurs at this time varies depending on the state of folds, wrinkles, etc. of the banknote 11, the number of stacked banknotes, and the like. Also, use this as guide 3,
5, the pressure between the P roller 2 and the banknote 11 required to feed out the banknote 11 pressed against the P roller 2 side by the push plate 1 (1 kg
Therefore, in the separating and feeding mechanism of the present invention, as shown in FIG. By appropriately setting the spring constant of the spring 9 that biases the guides 3 and 5 so that the guides 3 and 5 rotate,
moves up and down according to the stacked state of the banknotes 11, and the banknotes 11 are guided in the direction of the F roller 6 while keeping the pressure between the guide rollers 10a, 10b and the banknotes 11 substantially constant. Therefore, P
The pressure between the roller 2 and the banknote 11 is also stabilized. In addition, even if the banknote 11 has strong folds or wrinkles like a banknote that has been in circulation, the guide roller 10
a and 10b can reduce the frictional resistance force generated between the banknote 11 and the guides 3 and 5, that is, the frictional resistance force opposing the direction in which the banknote 11 is sent out. By increasing the urging force of the banknotes 11, it is possible to further improve the effect of smoothing out folds and wrinkles in the banknotes 11 by the guides 3 and 5 and the guide rollers 10a and 10b.

On the other hand, when the banknotes 11 are separated and fed out by the F roller 6 and the G roller 7, if the banknotes 11 are partially folded or wrinkled, the banknotes 11 may skew and be fed out to the next stage or stagnate. However, by making the guide rollers 10a and 10b protrude by a predetermined distance from the guides 3 and 5, the guide roller 10
The guide 3,
5, it can be extended to a predetermined size or less, and this can be prevented. At this time, banknotes 11
and guides 3, 5 and guide rollers 10a, 1
Since most of the pressing force between the banknote 11 and the banknote 11 generated between the banknote 11 and the banknote 11 is applied to the guide rollers 10a and 10b, the frictional resistance force opposing the banknote 11 feeding direction does not increase significantly. It is also possible to suppress the imbalance of frictional resistance that occurs between the left and right sides. Note that the protrusion dimensions of the guide rollers 10a and 10b from the guides 3 and 5 are based on the folding and wrinkle limits of the banknotes 11 to be handled, and the F roller 6,
Based on the separating and feeding performance of the banknotes 11 formed by the G roller 7, it can be experimentally set to a value of several mm.

In this way, the guide 3 that regulates the extraction direction,

It is possible to realize stable movement and feeding of banknotes 11 without being affected by this. Since the left and right guides 3 and 5 are supported independently and movably, it is possible to equalize the resistance on the left and right sides of the banknote 11 during feeding, and to prevent skew during feeding that occurs due to imbalance.
can be eliminated. guide roller 10a,
10b is provided to maintain a constant distance between the guides 3, 5 and the banknotes 11, the frictional resistance between the guides 3, 5 and the banknotes 11 is reduced, and the banknotes 11 are
Prevents bending, tearing, and jamming. Since the banknotes 11 can be fed out sequentially at regular intervals,
It is possible to prevent the sent banknotes 11 from jamming during transportation. In an automatic teller machine that counts and re-accumulates banknotes, the reliability of operation can be improved by stably and reliably performing processes such as banknote discrimination.

〔Effect of the invention〕

As explained above, according to the present invention, in the separating and feeding mechanism that separates and feeds stacked paper sheets one by one, the P roller 2 moves the paper sheets moving in the direction of the F roller 6 to the guide roller. Since the guides 10a and 10b correct the concave bulge, it is possible to prevent paper sheets from skewing, jamming, etc., and to stabilize the operation of the separating and feeding mechanism.
