Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet transport processing apparatus such as a cash dispenser (CD), an automatic teller machine (ATM), a printing apparatus, etc. The present invention relates to a paper sheet feeding mechanism for feeding a sheet one by one to a transport unit.

[0002]

2. Description of the Related Art FIGS. 17 and 18 are a schematic plan view and a schematic side view of an example of a conventional paper sheet feeding mechanism. In the figure, reference numeral 1 denotes a pick roller, which is in contact with the upper surface of the stacked sheets 2. 3 is a feed roller,
It is connected to the pick roller 1 by a gear mechanism (not shown), and is rotated at the same peripheral speed as the pick roller 1 by a roller drive motor (not shown) to send out the paper sheets 2 to the left.

Reference numeral 4 denotes a separator, which passes only the uppermost sheet of the stacked sheets 2 to the side of the transport path 5 and prevents the second and subsequent sheets from advancing. . The separator 4 uses a frictional force to prevent the second and subsequent sheets from advancing, so that a rubber material having a large friction coefficient is usually used.

[0004] The feed rollers 3 and the separators 4 are alternately arranged in the Y-axis direction, and the feed rollers 3 and the separators 4 are arranged so as to partially overlap when viewed from the Y-axis direction. . Hereinafter, the overlapping portion is referred to as an overlap 6. Due to the overlap 6, the paper sheet 2 sent to the transport path 5 is bent and wavy in the Y-axis direction.

Reference numeral 7 denotes a conveying roller, and an overlap 6
Is sent out to the transport path 5. Reference numeral 8 denotes a passage detection sensor that detects the passage of the paper sheet 2, for example, includes a pair of light emitting elements and a light receiving element, and a light beam 9 extends from the light emitting element to the light receiving element.

When the front end of the paper sheet 2 that has passed through the transport roller 7 crosses the light beam 9, the light beam 9 does not reach the light receiving element and the passage detection sensor 8 is turned off.
When the rear end of the paper sheet 2 passes through the light beam 9, the light beam 9
Again reaches the light receiving element, and the passage detection sensor 8
Is turned on.

A roller control means (not shown) controls a roller drive motor (not shown) using an ON / OFF signal from the passage detection sensor 8 to intermittently rotate the pick roller 1 and the feed roller 3 to keep paper sheets constant. Send out at intervals.
A stage 10 presses the paper sheets 2 against the pick roller 1 and the feed roller 3 with a constant pressing force 11 by a pressing mechanism (not shown).

[0008]

The performance of the separator 4 for separating only one sheet 2 includes the frictional force between the feed roller 3 and the sheet 2, the frictional force between the separator 4 and the sheet 2, The frictional force between the sheets 2, the stiffness of the sheets 2, the distance between the feed roller 3 and the separator 4 in the Y direction, the shape of the separator 4, and the degree of the overlap 6 (hereinafter, referred to as the overlap amount) ) And so on.

[0009] Of these, is a value determined by the type and state of the paper sheets 2 stacked on the stage 10, and the value constantly fluctuates within a certain range. On the other hand,
Is a value determined by design, and remains constant during operation of the apparatus. Therefore, there were the following problems.

(1) The separation state of the paper sheet 2 includes the frictional force between the feed roller 3 and the paper sheet 2, the separator 4 and the paper sheet 2.
The friction coefficient of the paper sheet 2 greatly varies (particularly, the friction coefficient of a banknote, which is a kind of the paper sheet 2, varies depending on the friction force between the paper sheets 2 and the friction force between the paper sheets 2). (Large), it may be necessary to feed out the paper sheet 2 whose coefficient of friction deviates greatly from the average value, but in this case, non-feeding or double feeding is likely to occur.

(2) When separating paper sheets 2 whose properties such as friction coefficient and stiffness deviate significantly from the average value,
Since the overlap amount is not the optimum value for the paper sheet 2, non-feeding or double feeding occurs due to this. In particular, in the case of a device for handling banknotes, non-feeding and double feeding are likely to occur because officially sealed tickets and circulation tickets have significantly different coefficients of friction and stiffness.

(3) The amount of overlap is an important factor influencing the separation performance of the sheet 2. The allowable setting of the amount of overlap is about the thickness of the sheet 2, for example, ± 0.1.
Since it is about 1 to ± 0.2 mm, it is not easy to set the amount of overlap within this allowable value at the time of manufacturing and to maintain it for a long time.

(4) When a large number of paper sheets 2 are fed out, the surface of the separator 4 is gradually worn, so that the amount of overlap is gradually reduced and double feed is likely to occur.

The conventional paper sheet feeding mechanism shown in FIGS. 17 and 18 utilizes a frictional force. In addition, a paper sheet adopting a method of bending and separating paper sheets is used. A leaf feeding mechanism is also known.

For example, JP-A-61-169428 (paper feed mechanism in a printer) discloses that a first pick roller is rotated in the reverse direction with respect to a paper running direction immediately before the running of a paper, and a second pick roller is rotated. After rotating the first sheet in the paper traveling direction, the first sheet is bent so as to be sandwiched, floated from the second sheet, and an air layer is formed between the two sheets to separate the first sheet. A mechanism for feeding out a first sheet by rotating a first pick roller in a paper traveling direction and stopping rotation of a second pick roller is disclosed.

However, according to the disclosed technology, since the deflection of the first sheet is formed between the first pick roller and the second pick roller, when the first pick roller is rotated in the sheet running direction, the first sheet is bent. The deflection of the first sheet is eliminated and the first sheet approaches the second sheet and re-contacts the second sheet. Where the first sheet comes into contact with the first pick roller, Since the second and subsequent sheets are also pressed in the direction of the first pick roller, the second sheet is the first sheet due to the frictional force acting between the first sheet and the second sheet. Is likely to cause double feed,
There is such a problem.

Japanese Patent Application Laid-Open No. 6-16257 (printer) discloses that after a sheet is bent by a first sheet feeding roller and a claw provided in a sheet feeding case, the bent portion can be rotated. There is disclosed a technique in which a sheet is lifted up by an auxiliary roller to release the leading end of the sheet from the claw, and the picked-up portion is pressed against a second sheet feeding roller to convey the sheet.

However, according to the disclosed technology, the auxiliary roller is rotated and inserted into the bent portion of the sheet, so that it is necessary to take a large amount of bending. The paper may be moved to the center and wrinkles may occur during conveyance. The rotation of the auxiliary roller is a reciprocating movement, so if the paper supply speed is increased, vibration occurs and it is not suitable for high-speed paper supply And so on.

In view of the foregoing, the present invention provides a paper sheet feeding mechanism capable of stably separating and feeding various sheets without fail or double feeding. The purpose is to do.

[0020]

A sheet feeding mechanism of the present invention includes a pressing mechanism for pressing a plurality of stacked sheets from one side in the stacking direction and a paper mechanism from the other side in the stacking direction. A deflecting roller that abuts against the leaves and deflects the abutting papers so that a central portion in a direction perpendicular to the transport direction is lifted, a feed roller that feeds the deflected papers in the transport direction, and It has a gate mechanism that allows only paper sheets to pass through.

According to the present invention, the first sheet is bent by the bending roller so that the central portion in the direction perpendicular to the conveying direction is lifted, and is separated from the second sheet.
Then, the bent first paper sheet is fed in the transport direction by a feed roller. In this case, the first sheet and 2
Since there is a gap between the first sheet and the second sheet, even if the coefficient of friction of the sheet is large, there is a gap between the first sheet and the second sheet. Does not generate large frictional force.
Therefore, even if the coefficient of friction of the paper sheet is large, the non-feed phenomenon does not occur.

Also, when the first sheet is fed, even if the second and subsequent sheets are about to be fed together with the first sheet due to frictional force, they are not bent. The gate mechanism that allows only the folded sheets to pass allows only the bent first sheet to pass, and prevents the second and subsequent sheets from passing. Therefore, the double feed phenomenon does not occur.

The first paper sheet 22 is separated using the gap generated between the first paper sheet 22 and the separated first paper sheet 22 has a large frictional force with the second paper sheet 23. Since it does not act, it is less susceptible to fluctuations in the coefficient of friction of paper sheets as compared with the conventional separation method using frictional force.
