Description

[Detailed description of the invention] [Summary] By providing a spring plate that forces the attitude of the paper sheet fed out by the pick crawler in the thickness direction and guides it to a predetermined gap formed by the feather spring, the paper sheet is The structure is designed to prevent jamming as much as possible during separation.

[Industrial application field]

The present invention relates to a paper sheet taking-in device equipped with a feeding mechanism that takes in all the paper sheets inputted into an input slot and separates the taken-in sheets to feed them out. The present invention relates to a paper sheet taking-in device that stabilizes the feeding of paper sheets.

Automated deposit machines that automate the deposit process and are capable of verifying the authenticity of all banknotes inserted by the depositor.
Denomination discrimination is performed automatically one after another, and those identified as defective banknotes are returned through the return slot, while those identified as genuine banknotes are stored in a banknote storage box.

FIG. 1 shows an overview of the banknote conveyance mechanism, particularly the banknote conveyance mechanism of the automatic deposit machine of the batch loading type.

The depositor stacks all the banknotes to be deposited and inserts them into the slot OP ₁ as a banknote bundle. At this time, the shutter
Since SH is open, the inserted bill bundle is inserted up to the stopper SP.

When the insertion of this bundle of banknotes is detected by the photosensors PS ₁₁ and PS ₁₂ , the stopper SP is lowered and evacuated, and the belt _B2 is lowered to the position shown by the dotted line, and the banknote bundle is moved between the belts _B1 and B. ₂ .
Transfer in the direction of the arrow.

When the leading end of the banknote bundle reaches the photosensor PS ₁₄ , the banknote bundle is detected by the photosensors _PS12 to _PS14 , but the banknote bundle is no longer detected by the photosensor _PS11 .

Accordingly, it is determined that the banknote bundle has been normally inserted through the detection by the photosensors PS ₁₁ to _{PS 14} , the shutter SH is closed, and the banknote bundle is transferred to the input section TB.
It will be sent to the Identification Department DB.

In this case, if the bundle of banknotes is inserted in a folded state or in an uneven state that is shifted from front to back,
Since the length of the bill bundle becomes too small or too long, the above-mentioned detection conditions are not satisfied, and in this case, belts B ₁ and B ₂ are reversed to return the bill bundle.

When the banknote bundle is inserted normally, the pit crawler R ₁ and the separation roller R ₂ , which have minute irregularities on the surface of the feeding mechanism ME indicated by dotted lines, rotate to separate the banknote bundle one by one and send it to the discrimination section DB. send to

When the tail end of the sent banknote is detected by the photo sensor PS ₁₀ , the next banknote is sent, and the feeding operation of this banknote continues until the input banknote bundle runs out or the storage section TB
This continues until the maximum allowable number of shots is reached, for example, 50 pieces.

The bill conveyance speed in the discriminating section DB is considerably faster than that at the input section TB, and therefore the rollers of the dispensing section TB near the discriminating section DB are of a free-wheel type.

While being conveyed at high speed through the identification section DB, the banknotes are identified for denomination (10,000 yen, 5,000 yen, or 1,000 yen) and authenticity. (The mechanism of the identification section DB is complex, so only a part of it is shown in the drawing.) If the identification result is good (authenticity and the denomination was detected), the gate RTM outputs the data from the identification section DB. The received banknotes are sent to the guide GU of the store section SB using belts B ₄ and B ₅ .

When the banknotes are fed onto the guide GU and loaded, they are detected by the photo sensors PS ₄₂ to PS ₄₄ , and the motor _M1 is activated to move the banknotes to the belt _B6 by the pusher PSH.
push it down onto the

At this time, the guide GU supporting both sides of the banknote
is retracted to the left and right, and belt B ₆ is in a stopped state.

If the identification result is bad, the banknote is exposed to the photo sensor.
When detected by PS ₂₃ , gate RTM rotates counterclockwise and discharges the bill to return port OP ₂ via belts B ₇ to B ₁₀ . In addition, when the ejected banknotes pass through the photo sensor PS ₂₅ , the gate RTM
returns to its original state.

When all the input banknote bundles have been identified and dropped onto the belt B ₆ and loaded, the front panel (not shown) of the automatic deposit machine will display the total amount of the input banknotes, and A message will appear asking if you wish to make the deposit.

If the depositor is OK, press the button marked with a
If not, press the button marked with an x.

When the button marked with 〇 is pressed, the motor _M1 operates again, and by suppressing both edges, the banknotes stacked on the belt _B6 are pushed into the banknote storage box by the pusher PSH.
When it is dropped into the CAM and the button marked with an x is pressed, belt B ₆ rotates, and then belt B ₆ is rotated by belts B ₇ to _{B 10.}
Return all of the stacked banknotes to return slot OP ₂ .

In such an automatic deposit device, if the bundle of banknotes taken in at once by being inserted into the slot OP ₁ is folded, or if the banknotes are misaligned and shifted from front to back, the banknotes will not be inserted correctly. Furthermore, if the banknote bundle is separated one by one by the feeding mechanism ME and sent to the discrimination section DB, and the banknote bundle is found to be defective as a result of the discrimination, it will be returned in the same manner.

Therefore, deposits can be made by re-inserting the returned banknote bundle by, for example, arranging the banknotes if they are uneven or unfolding the banknotes if they have been folded.

However, if a jam occurs during the transfer of such bundles of banknotes, the processing must be interrupted and the handling of the automatic deposit machine must be stopped.

Therefore, it is desired that the transfer of banknote bundles in such automatic deposit machines be highly reliable.

[Conventional technology]

Conventionally, the configuration was as shown in the conventional explanatory diagrams of a and b in FIG. 3.

As shown in Fig. 3 a and b, the above-mentioned feeding mechanism
The ME has a friction plate 3 made of rubber material etc.
A pressurizing plate 1 to which a presser plate 2 and a presser plate 2 are fixed and which is swingable in the direction of arrow a is provided opposite to the pick roller _R1 .

Further, a feather spring 5 is disposed in front of the presser plate 2.

Then, the paper leaf 6 corresponding to the banknote forming the banknote bundle transferred by the belts B ₁ and B ₂ mentioned above is taken in as shown by arrow C, and the tip of the paper leaf 6 is brought into contact with the friction plate 3 and the pick roller. It is located at the contact part with _R1 .

Next, due to the rotation of the pick crawler R ₁ in the direction of arrow B, the paper sheet 6 that is in contact with the pick crawler R ₁ side is rotated.
is taken in by raising the pressure plate 1, and is drawn out by being held between the friction plate 3 and the pick roller _R1 .

In this case, the paper sheet 6 that is in contact with the friction plate 3 side
is a brake due to the friction of the friction plate 3 and is not extended.

Therefore, the paper sheets 6 are fed out one by one from the pick crawler _R1 side.

Further, the paper sheet 6 fed out by the pick crawler R ₁ passes through the gap S formed by the tip of the feather spring 5 and the guide member 7 with its leading end being guided by the presser plate, and is fed out. Ru.

This gap S is usually adjusted according to the thickness of the paper sheet 6 to be passed through so that one sheet of paper sheet 6 can pass through, and is formed so as to be maintained at a predetermined value. ing.

Therefore, the paper sheet 6 can be reliably separated into one sheet by passing through the feather spring 5 and sent to the above-mentioned discrimination section DB.

[Problem that the invention attempts to solve]

However, in such a configuration, if the paper sheet 6 has a curl or warp, the paper sheet 6 fed out by the pick crawler _R1 will become curved and buckled, as shown in FIG. 3a. It may be done.

In addition, in order to prevent such buckling of the paper sheet 6 due to its tendency to fold, it is possible to prevent it by pressing it with a member 3a indicated by diagonal lines as shown in FIG. If the tip of the paper sheet 6 has a tendency to warp or curl, the tip will not be inserted into the gap S and will be bent along the feather spring 5, making it impossible for the paper sheet 6 to pass through the gap S.

Therefore, in such a case, it becomes Jiyam,
There was a problem in that subsequent processing became impossible, the processing had to be interrupted, and the handling of the device had to be stopped.

[Means for solving problems]

Therefore, the present invention provides a pick crawler R ₁ which is disposed facing the friction plate 3 so as to feed out a plurality of paper sheets in a predetermined number at a time, and which is disposed with a predetermined gap formed therebetween _. In a paper sheet taking-in device equipped with a feather spring 5 for taking in a predetermined number of sheets fed out, the feather spring 5 contacts the sheet fed out from the pick crawler _R1 , and A spring plate 4 is provided which forces the posture, has a thickness corresponding to the predetermined number of plates, and guides the plate to the predetermined gap position.

With this configuration, the above-mentioned problems are solved.

[Effect]

That is, by pressing the sheet of paper fed out from the pick crawler and forcing the posture of the sheet of paper in the thickness direction, the sheet of paper is guided to the position of the gap S formed at the tip of the feather spring, thereby ensuring that the sheet of paper passes through. This is how it was done.

Therefore, even if the paper sheet has the above-mentioned folding, warping, or curling tendency, the paper sheet is regulated by the guide of the spring plate, and the jamming that conventionally occurs can be prevented. It is possible to perform stable feeding.

〔Example〕

The present invention will be explained in detail below with reference to FIG.
FIG. 2 is an explanatory view of one embodiment of the present invention, in which a is a perspective view and b is a side view. The same reference numerals indicate the same objects throughout the figures.

As shown in FIG. 2a, a spring plate 4 that protrudes so as to overlap on both sides of the feather spring 5 is glued or otherwise attached to a presser plate 2 provided on a pressure plate 1 that is swung in the direction of arrow a. The other components are the same as those described above.

Then, the leading end of the paper sheet 6 fed out by the rotation of the pick roller R ₁ is inserted into the gap S at the leading end of the feather spring 5 under the guidance of the spring plate 4 .

Therefore, even if the sheet of paper 6 has a tendency to fold, warp, or curl as described above, the tip of the sheet of paper 6 will be straightened as shown in FIG. 3b by the guidance of the spring plate 4. It is possible to force the posture of each paper sheet 6 in the thickness direction so that the feeding is not stopped due to contact with the feather spring 5, and reliable transfer can be performed.

Note that even if such a spring plate 4 is provided, the spring plate 4
is raised and lowered by the swinging of the pressure plate 1, so even if the thickness of the paper sheet 6 differs, it is possible to always perform pressing and guiding according to the thickness, and there is no problem in conveying the paper sheet 6. It can be formed so that it does not occur.

[Effect of idea]

As explained above, according to the present invention, the spring plate fixed to the presser plate allows the posture of the paper leaf in the thickness direction when the paper leaf is let out by the rotation of the pick crawler and passes through the feather spring. can be forced.

Therefore, by preventing jams caused by folding, warping, or curling of paper sheets, which conventionally occur when paper sheets are fed out, reliability can be improved and the practical effect is great.
