Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a paper sheet take-in device, and in particular to a paper sheet take-up device that can reliably separate and feed out paper sheets that have been input in bulk one by one. Regarding the loading device.

A bulk deposit automatic deposit machine that automates deposit processing,
Authenticity and denomination of all banknotes inserted by depositors are automatically determined one after another.

As a result of this discrimination, banknotes that are determined to be defective are returned from the return slot, while banknotes that are determined to be genuine are stored in the banknote retrieval device.

FIG. 1 shows an overview of the bulk deposit type automatic deposit machine, particularly the banknote transport mechanism.

The depositor stacks all the banknotes he wants to deposit and opens the slot.
Put it in 1.

At this time, since the shutter SH is up, the inserted banknote bundle is inserted up to the stopper SP.

Insertion of banknotes is done using photo sensor PSI 1. When detected by PSI 2, the stock tip XSP is lowered, and the belt B2 is lowered to the dotted line position, and the bundle of banknotes is pinched together with the belt B1 and sent in the direction of the arrow.

When the tip of the bill bundle comes to the photo sensor ps14, the photo sensors ps14 to ps12 detect the bill bundle, and the photo sensor p
At s11, the banknote bundle is not detected.

Under these conditions, the insertion of banknotes is judged to be normal, and the shutter SH is
The falling banknotes go from the input section TB to the discrimination section DF! yX will be sent.

On the other hand, if the banknotes are inserted folded or in a misaligned manner, the length of the banknote bundle (length in the direction of conveyance) will be too small or too large, and the above conditions will not be satisfied. , at this time belt B1. B2 is rotated in the opposite direction and the inserted bill is returned.

When the banknote bundle is inserted normally, the feeding function M indicated by the dotted line
The intake roller (hereinafter referred to as pick roller) that constitutes E
R1 and a separating/feeding roller (hereinafter referred to as a separate roller) R2 rotate to separate and feed the banknotes one by one and send them to the discrimination section DB.

When the tail end of the banknote sent to the discrimination WpB is detected by the photosensor PS16, the next banknote is sent from the feeding function card.

This bill feeding operation continues until there are no more inserted bills, or until the maximum allowable number of bills in the stacking section (hereinafter referred to as the store section), SB, reaches, for example, 50 bills.

The banknote conveyance speed in the discriminating section DB is considerably faster than that at the input section 'm, and therefore the rollers of the input section TB near the discriminating section DB are of a freewheel type.

While the banknotes are transported at high speed by the discrimination unit DB, the denomination (-10,000 yen, 5,000 yen, 1,000 yen) and authenticity are determined (
Although the mechanism of the discrimination section DB is complex, only a part of it is shown in the drawing).

If the verification result is good (the banknote is genuine and the denomination has been detected), the gate RTM transfers the banknote that came out from the verification unit DB to the belt B4. It is sent to the guide unit GU of the store unit SB via B5.

When the bill is on the guide part GU, this is the photo sensor PS.
42, the motor M1 operates and the pusher PS
The banknotes on the guide part GU are pushed down onto the belt B6 via H.

At this time, the guide GU supporting the front side of the banknote opens left and right, and the belt B6 is stopped.

If the discrimination result is bad, the gate RTM rotates counterclockwise when the banknote is detected by the photosensor Ps23, and the banknote is discharged to the return port OP2 via the belts B7 to BIO.

When the discharged banknote passes the photo sensor ps25,
Gate RTM is restored.

When all the inserted banknotes are verified and dropped onto the bell B6 and stacked, the front panel of the automated teller machine will display the total amount of the inserted banknotes, and you will be asked whether or not to deposit this amount. Display a message asking the person to contact you.

The depositor looks at this displayed amount and approves the deposit (OK
), press the button marked with an O symbol.

Also, if the deposit is not approved, the user will press the button marked with an x mark.

When the ○ button is pressed by the depositor, the motor 1 is activated again and the banknote bundle on the belt B6 (this belt also holds the good edges of the banknotes) is transferred to the canister (
Banknote storage box) Drop into CAN.

On the other hand, when the depositor presses the x button, the belt B6 rotates, and the banknote bundle, that is, all the inserted banknotes are returned onto the belt B6 along the path from belt B7 to BIO.

[Conventional technology]

By the way, the banknote dispensing function M of the automatic deposit machine having such a configuration
The mechanism in E is configured to separate the inserted banknote bundle one by one and send it to the discrimination section DB.

More specifically, a feather spring was provided on the bill taking-in conveyance path between the pick roller R1 and the separate roller R2, and a friction chip was also fixedly provided opposite the separate roller R2.

The feather spring is a banknote separation member that forms an interval corresponding to one banknote on the banknote take-in conveyance path and allows only one of the banknotes taken in by the pick roller R1 to pass through.

Conventionally, this feather spring was constructed from a thin leaf spring.

Further, the friction chips provided opposite to the separate roller R2 were also supported and fixed opposite to the separate roller R2 with an interval corresponding to the thickness of one banknote.

[Problem that the invention attempts to solve]

However, banknotes that are warped or curled are mixed in the bundle of banknotes that are thrown in at once.

In such a case, a feather spring made of metal such as a leaf spring has a problem in that it is difficult to pass such deformed banknotes.

This problem can be solved to some extent by slightly increasing the bill passing interval by the feather spring.

However, for example, banknotes of different denominations have different length dimensions.

Therefore, when banknotes of different denominations are stacked and thrown in, a situation occurs in which the leading edge of the upper banknote protrudes and covers the leading edge of the lower banknote between the stacked banknotes.

In this case, the tip of the upper bill enters not only the feather spring but also the separate roller R2 first, leading to a situation such as two bills being fed out (there is a drawback).

[Means for solving problems]

In order to solve the above-mentioned problems, this invention reliably separates paper sheets one by one, even if the paper sheets are deformed or the leading edge of the upper sheet is protruding from the leading edge of the lower sheet. It is an object of the present invention to provide a paper sheet taking-in device that allows paper sheets to be fed out.

To this end, in the present invention, a separating member with elasticity is provided in the sheet taking-in and conveying direction on the sheet taking-in conveying path between the taking-in roller (pick roller) and the feeding roller (separate roller). The separation member is arranged so as to close the conveyance path.

Further, a friction member is provided via an elastic support member to face the delivery roller located at the rear stage of the intake path.

In other words, this friction member has elasticity so as to bias it in the direction of the delivery roller.

[Effect]

By configuring the separating member with a member having elasticity in the direction of taking in and transporting paper sheets, such as synthetic resin (rubber material), the tips of the banknotes sent by the taking-in roller are aligned in an orderly manner along the curved surface of the separating member. Ru.

Further, the friction member corresponding to the feeding roller can be moved back and forth with respect to the surface facing the feeding roller.

Therefore, even if the separating member accidentally separates two sheets, the two sheets can be passed through and fed out as they are.

The present invention will be described in detail below using examples.

〔Example〕

FIG. 2 is an embodiment showing the banknote separating function section of the feeding mechanism according to the present invention.

In the same figure, pick roller R1 and separate roller R
2 correspond to the rollers R1 and R2 in FIG. 1, respectively.

The bill separating function section of the feeding mechanism in this embodiment includes a pick presser IA, a presser plate IB, a base 2, and guide plates 3A and 3.
B, consists of a bracket 4 and a feather spring 5.

The banknotes 6 thrown in at once reach the pick roller R1 as described above.

The pick presser IA is biased from the direction P in the figure and acts to press the banknote 6 in the direction of arrow P' centering on the rotation pin IC.

The pick roller R1 rotates in the direction of the illustrated arrow, and transfers the banknotes that come into contact with this roller (the lowest banknote in the figure) to the separation roller R2 side.

In reality, due to the relationship of friction between the banknotes 6, the bent portion l of the presser plate 1B fixed to the pick roller R1 and the pick presser IA.
The banknote 6 sandwiched between B' and B' is sent out.

The fed banknotes reach the inclined portion IB'' of the holding plate IB.

This inclined portion 1B'' is formed in a tapered shape, and has a function of shifting the tip of the banknote 6 that is abutted against this tapered portion to a different level as shown in the figure.

However, when the leading edge of the upper banknote protrudes from the leading edge of the lower banknote, the one-shift action by the inclined portion 1B'' does not function effectively.

Next, the banknote 6 moves forward along a paper sheet taking-in conveyance path constituted by the base 2, guide plates 3A, 3B, and the like.

Then, the feather spring 5 attached to the bracket 4 is reached.

In this embodiment, the feather spring 5 is made of an elastic material such as synthetic resin.

Therefore, when the banknote 6 enters, the feather spring 5 is bent by the tip of the banknote 6 as shown in FIG.

As a result, each tip of the banknote 6 is completely shifted along the curved surface of the feather spring.

As mentioned above, the feather spring 5 is conventionally made of a rigid material such as metal, and has a gap A with the guide plate IB.
It was necessary to set the interval to correspond to the thickness of one banknote.

However, in this embodiment, by changing the material of the feather spring 5 to an elastic body, the distance t can be reduced as shown in FIG.
The feather spring 5 can be displaced within the range indicated by .

As a result, it becomes possible to completely perform the 1st part of the banknote 6.

Further, even if the gap A is set to zero, the elasticity of the feather spring 5 allows the banknotes 6 to pass through, and there is no need to spend a lot of effort to set the gap A as in the conventional case.

FIG. 3 is a diagram showing an embodiment of the banknote feeding function section of the feeding mechanism.

In the figure, the separate roller R2 corresponds to the separate rollers in FIGS. 1 and 2.

This banknote feeding function section is provided after the banknote separation function section shown in FIG. 2, and is composed of a lever 7, an adjustment screw 10, a frame 8, a friction tip 13, a spring plate 14, and the like.

The banknotes 6 separated (shifted) by the feather spring 5 described in FIG. 2 are sent out to this separation roller R2.

As shown in FIG. 3, in this embodiment, the separate roller R2
A friction tip 13 made of synthetic resin is fixed to the lower outer periphery of a spring plate 14 having a substantially U-shaped cross section.

This spring plate 14 is attached to one end of the lever 7.

The lever 7 is rotatably supported by a rotation pin 12, and the other end is connected to the frame 8 by a spring 9 and an adjustment screw 10.

Therefore, by adjusting the rotation of the adjusting screw 10, the lever 7 can be moved up and down in the direction of arrow C by the tension of the springs 11 and 9.

As a result, the lever 7 suspended by the spring 9 rotates around the rotation pin 12, so the friction tip 1
3 and the separate roller R2 can be set to a distance corresponding to the thickness of one banknote 6.

Conventionally, this friction chip 13 was directly fixed to the lever 7.

Therefore, the gap between the chip 13 and the separate roller R2 was completely fixed.

Therefore, if two bills were to be sent out at the same time, they would not be able to pass through the gap B, and the bills would become jammed (jam occurred).

In this embodiment, this friction chip is elastically supported by the spring plate 14, so that even if two stacked banknotes should reach the separating roller R2, the gap B will be widened, and jamming can be prevented as much as possible.

As already mentioned, when two stacked banknotes pass through the separate roller R2, they are detected as defective banknotes by the discrimination section DB (FIG. 1) and returned to the depositor.

Then, the two-sheet banknote can be processed by being re-inserted by the depositor.

As described above, in this embodiment, by configuring the feather spring, which is the separating member, from an elastic body, it becomes possible to separate banknotes that have been thrown in at once into different levels in an orderly manner.

In addition, by elastically supporting the friction tip facing the separate roller R2 with a U-shaped spring plate, even if two bills are fed, they can be fed smoothly without jamming. It becomes possible to feed out stable banknotes.

[Effect of idea]

As explained above, according to the present invention, it is possible to reliably and stably take in banknotes one by one, and the practical effect when applied to a bulk deposit type deposit machine or the like is great.
