Description

[Detailed description of the invention] [Summary] The present invention is a feeding device that feeds out stacked paper sheets at least one sheet at a time, and detects whether or not the pressure applied to the feeding means is equal to or higher than a predetermined pressure. When the pressing force is a predetermined pressure, a pressure reducing means is provided to move the paper sheet in a direction that reduces the pressure, so that a constant pressure is applied to the feeding means, thereby ensuring reliable feeding of the paper sheet. This is what made it possible.

[Industrial application field]

TECHNICAL FIELD The present invention relates to a paper sheet dispensing device used in an automatic cash transaction machine or the like, and particularly to a paper dispensing device for dispensing at least one sheet at a time from a large amount of paper sheets stored therein.

2. Description of the Related Art Automated cash transaction devices and the like usually include a so-called safe for storing banknotes therein, and are configured to dispense banknotes from this safe.

[Conventional technology]

FIG. 3 is a diagram showing a conventional sheet feeding device.

2-b is a delivery roller, 33 is a detector, 35 is a pressing member, 36 is a drive belt, 39-a is a roller support member, 39-b is a roller support spring, 40 is a motor, and 41 is a motor control unit. .

shows the fixed part where is fixed.

Paper sheets, such as banknotes, are accumulated and stored in the paper sheet storage section 31 as shown in the figure.

A feed-out roller 32 for feeding out paper sheets is provided in the lower part of the paper sheet storage section 31, and feeds out at least one sheet at a time from the paper sheet storage section 31.

Normally, that is, when paper sheets are fed out, the feeding roller 32 and the roller support member 39-a are in the position shown by the broken line in the figure. In other words, paper sheet storage 3
When a large amount of paper sheets is stored in the tray 1, the weight of the paper sheets is applied to the feeding roller 32, and the feeding roller 32 moves downward to the position shown by the broken line. As a result, when the roller support member 39-a presses down the switch of the detector 33, the detector is turned on.
state.

The roller support member 39-a is the roller support spring 3
9-b pushes it upward.

In other words, the weight of the paper sheet and the roller support spring 3
The upward force of the roller 9-b increases the friction between the feeding roller 32-b and the sheet, so that the sheet can be reliably fed.

However, by feeding, the number of paper sheets decreases,
Or, when the number of sheets to be stored is small, the feed roller 3
When the force applied to 2, that is, the pressure pushing down the feed roller 32 is small, the roller support member 39-a is lifted by the roller support spring 39-b.

This causes the switch of the detector 33 to go up and become OFF. The control unit 41 detects that the pressure applied to the feeding roller 32 has become smaller by detecting that the detector 33 has turned off. Then, the control section 41 drives the motor 40.

When the motor 40 is driven, the drive belt 36 connected to the motor 40 moves in the direction of arrow C in the figure, and the pressing member 35 moves in the direction of pressing the paper sheet. The paper sheet is pressed by the pressing member 35,
The friction with the feeding roller 32 is increased, allowing reliable feeding of paper sheets.

[Problem that the invention attempts to solve]

However, in the conventional technology, the feeding roller 32
When the pressure applied to becomes small, the pressing member 35
However, when a large amount of paper sheets is stored in the paper sheet storage section 31, the pressure applied to the feeding roller 32 is too large and the force of the feeding roller 32 is too large. This will result in a situation where it cannot be played.

Furthermore, if the feeding force of the feeding roller 32 is increased, it may cause the paper sheets to be torn. The object of the present invention is to solve the above-mentioned problem of allowing smooth feeding of paper sheets regardless of the amount of paper sheets accumulated in the storage section, and to provide a paper sheet feeding device.

[Means for solving problems]

FIG. 1 is a diagram showing the principle structure of the present invention.

Reference numeral 1 denotes a paper sheet storage means, 2 a feeding means, 3 a pressure detection means, and 4 a pressure reduction means.

In the figure, a sheet storing means 1 stores sheets in a stack, and a feeding means 2 feeds out the sheets stored in the sheet storing means 1 from the sheet storing means 1.

Further, the paper sheet storing means 1 described above is provided with a feeding means 2.
a pressure detection means 3 for detecting whether the pressure with which the is pressed downward is equal to or greater than a predetermined pressure; and the pressure detection means 3.
A pressure reducing means 4 is provided which operates based on the detection result.

[Effect]

As mentioned above, in other words, the pressure detection means 3 detects when the downward pressure applied to the feeding means 2 exceeds a predetermined value.
It detects whether or not pressure is being applied to the feeding means 2, and if the detected result is that a pressure of a predetermined level or more is being applied to the feeding means 2, the pressure reducing means 4 is operated, and the pressure reducing means 4 moves the paper sheets in a pressure reducing direction. , and the pressure applied to the feeding means 2 is reduced to enable smooth feeding of paper sheets.

〔Example〕

FIG. 2 is a diagram showing a sheet feeding device using the technology of the present invention.

11 is a banknote storage section, 12 is a feeding roller, 12
-b is a delivery roller, 13 is a pressure detection section, 14 is a pressure reduction belt, 15 is a pressure member, 16 is a pressure belt, 17 is a pressure reduction detector, 18 is an auxiliary roller, 19
-a is a support member, 19-b is a support spring, 20 is a motor, and 21 is a control unit.

The operation of the embodiment will be described below with reference to FIG.

The banknotes stored in the banknote storage unit 11 are fed out by a payout roller 12 provided at the bottom of the banknote storage unit 11, and sent out to a conveyance path by a delivery roller 12-b.

However, if too many banknotes are stored in the banknote storage section 11, the force applied to the feed-out roller 12, that is, the pressure to lower the feed-out roller 12 downward, increases, and the support member 19 along with the feed-out roller 12 increases.
-a goes down in the direction of arrow G shown in the figure.

Support member 19-a lowered in the direction of arrow G above
As a result, the control unit 21 detects that the switch of the pressure detector 13 has been pressed and a pressure of a predetermined level or more has been applied to the feeding roller 12. When the control unit 21 detects that a pressure of a predetermined level or more is applied to the feeding roller 12, the motor 20 is moved to move the decompression belt 14 and move the auxiliary roller 18 in the direction of the arrow A shown in the figure to move the lattice pattern shown in B in the figure. By sandwiching the paper money and moving the decompression belt 14 in the direction of arrow C by the motor 20, the bill is lifted upward. At this time, the pressing belt 16 also moves and lifts the pressing member 15 upward so as not to press the bill.

Further, when the number of bills is small and the pressure on the feeding roller 12 is insufficient, the support member 19-a moves in the direction of arrow F in the figure and presses down the switch of the decompression detector 17, causing the feeding roller 12 to press down. When the control unit 21 detects that the pressing force is small and insufficient, it moves the pressing belt 16 and uses the pressing member 15 to
Press by pressing down on the banknote.

Therefore, the support member 19-a is maintained between the pressure detector 13 and the reduced pressure detector 17 by pressing the feeding roller 12 with the bill and by supporting the spring 19-a.
It is held in b.

That is, by holding the support member 19 between the pressure detector 13 and the pressure reduction detector 17, the banknotes can be smoothly fed out from the banknote storage section 11.

〔effect〕

As described above, according to the present invention, regardless of the amount of paper sheets stored in the paper sheet storage means,
This enables smooth feeding and eliminates problems such as tearing of paper sheets due to excessive pressure.
