The media separating apparatus according to the present invention does not need to replace the rollers according to the difference in the thickness of the bills or the location of the braille for the visually impaired for each country or bill type, and is configured to solve the fear of the damage and jam of the media. It is to the technical point. That is, even if a thickness change occurs in the input medium, it is an important technical feature that it is configured so that there is no influence on separation and feeding of the medium.

As shown in the figure, the media separating device of the present invention is a device for separating predetermined media P, such as banknotes or checks, from the cassette one by one and conveying them in the conveying direction. It comprises a pair of take-out roller 20 and the conveying roller 25 for conveying the medium (P) and rotates in the same direction in conjunction with the roller 10, friction roller 10, and is basically a utility model registration agent It has the same operating configuration as 198800. The friction roller 10 is a means for initiating the transfer of the medium P. At least one pair is installed at the center of the first rotating shaft 1 located above the apparatus frame (not shown), and each friction roller 10 At least a portion of the circumferential surface of the) is composed of a friction pad (12). The pair of take-out rollers 20 are respectively provided with the pair of friction rollers 10 at the center of the second rotating shaft 2 installed horizontally with the first rotating shaft 1 below the first rotating shaft 1. Correspondingly provided, at least a portion of the peripheral surface of each take-out roller 20 is made of a take-out pad 22. The pair of take-out rollers 20 and the feed rollers 25 are installed on the second rotating shaft 2, and the feed rollers 25 are spaced apart from each other by a predetermined interval between the pair of take-out rollers 20 and the outside thereof. It is installed.

In the medium separating apparatus of the present invention, a structure using a pair of separating belts 42 instead of a pair of separating rollers of the prior art is provided as a means for separating the sheets one by one by supporting the lower end of the medium P. The pair of separation belts 42 are installed in correspondence with the drawing roller 20, and the fourth rotating shaft 4 located behind the second rotating shaft 2 and the pair of drawing rollers 20 It is supported by a pair of bearing shafts 5 which are positioned below the fourth rotary shaft 4 in the circumferential direction and slidably move away from the fourth rotary shaft 4. The bearing shaft 5 slides in accordance with the tension of the separating belt 42.

A pair of belt pulleys 40 corresponding to the drawing rollers 20 of the second rotating shaft 2 are provided on the fourth rotating shaft 4, and the pair of belt pulleys are provided on the pair of bearing shafts 5. A pair of belt bearings 50 corresponding to 40 are provided. On the pair of belt pulleys 40 and the belt bearing 50, the pair of separating belts 42 has a constant tension left and right, preferably in the rotational direction of the take-out roller 20, that is, conveyance. It is installed in an inclined state with a constant inclination in the furnace direction.

The fourth rotary shaft 4 is connected to a drive shaft or a third rotary shaft (not shown) by a motor (not shown), and preferably the first and second rotary shafts 1 are linked to the third rotary shaft. Rotate in the same direction as (2). At this time, the surface of the separation belt 42 and the take-out roller 20 at the contact portion of the separation belt 42 and the take-out roller 20 driven by the belt pulley 40 on the fourth rotating shaft (4). Facing directions face away from each other. For example, when the take-out pad 22 of the take-out roller 20 advances in the conveying direction of the medium P, the surface of the separating belt 42 runs in the cassette direction opposite to that.

Preferably, the separating belt 42 rotates at a slower speed than the drawing roller 20. In this case, the second rotating shaft 2 provided with the drawing roller 20 and the driving shaft of the separating belt 42 are provided. The rotation ratio of the rotary shaft 4, that is, the rotation ratio of the take-out roller 20 and the belt pulley 40 may be set to 100: 1 to 200: 1, preferably 152: 1.

According to such a structure, when the medium P is taken out from the cassette, the medium P advances in the conveying path direction while the friction roller 10 and the extraction roller 20 rotate. The friction pad 12 and the take-out pad 22 transfer one medium P at one rotation of each of the rollers 10 and 20, wherein the first medium P located at the top of the cassette is the friction pad. It is in close contact with the surface of the drawing pad and is conveyed in the conveying path direction. On the other hand, while the first medium (P) is drawn out, the separating belt 42 proceeds at a lower speed than the take-out roller (20) to the cassette side opposite to the traveling direction of the takeout pad (22) and the first medium (P). The second medium P and the remaining medium P below are pushed to the cassette side. In this way, the remaining medium P including the second medium P is separated by the separation belt 42 driven in the reverse direction, and is not transported in the direction of the conveying path, thereby achieving more stable medium P separation.

On the other hand, the present invention does not require the configuration of the intermittent rotary motion mechanism and one-way bearings, etc. mentioned in the prior art, and in particular, by using the above-described rotation ratio difference can be configured to rotate the belt pulley 40 at a lower speed than the take-out roller 20. In this case, it is possible to prevent the occurrence of uneven wear due to the installation of the one-way bearing in the prior art.

On the other hand, in the medium separating apparatus of the present invention, when there is a change in the thickness of the medium P conveyed to the take-out roller 20, for example, the first medium P is folded in half or a plurality of times between these folded gaps. Of the take-out roller 20 and the separation belt 42, such as when another medium P is inserted or when a medium of different thickness is input due to different thicknesses or positions of the braille for the visually impaired. It includes a configuration that can solve the jam occurrence problem in the contact portion.

That is, it may be composed of a pair of suspension device 80 for connecting between the fourth rotary shaft 4 and the pair of bearing shaft 5 with a predetermined elastic force.

The pair of suspensions 80 are slid in the direction in which the bearing shaft 5 moves away from the fourth rotation shaft 4 in order to solve the problem of jamming at the contact portion between the take-out roller 20 and the separation belt 42. It provides an auto-tension function that restores the bearing shaft 5 to its original position independently of each other when moving.

Specifically, the pair of suspensions 80 may be composed of a hinge bracket assembly 84 and a compression spring assembly 85, respectively, to return the bearing shaft 5 to its original position.

Hinge bracket assembly 84 is coupled to the fourth rotating shaft (4) and the bearing shaft (5), both ends may be composed of first and second hinge brackets (82, 83) that are hinged to each other.

The compression spring assembly 85 elastically supports the hinge bracket assembly 84 from the outside, and contracts and relaxes in accordance with the separation belt 42 clearance.

For example, when a change occurs in the thickness of the medium P, such as when the first medium P is folded in half as described above, or when a plurality of other mediums P are sandwiched between these folded gaps, or When a medium P of very different thickness, for example a much thicker thickness, is introduced, the bearing shaft 5 moves in a direction away from the fourth rotational shaft 4, ie in the outward direction, whereby the suspension 80 ), Tension is applied to return the bearing shaft 5 to its original position.

Therefore, a certain play occurs between the separation belt 42 and the take-out roller 20 supported by the belt pulley 40 and the belt bearing 50 due to the movement of the bearing shaft 5, and through this play there is a problem. After passing through the medium P, the bearing shaft 5, that is, the belt bearing 50, is returned to its original position by the auto tensioning function of the suspension device 80.

When the braille for the visually impaired person is located on the left side and a medium P having a thickness greater than the thickness of the right side is inserted, only the left bearing shaft 5 moves in a direction away from the fourth rotating shaft 4. At 80, tension is applied to return the left bearing shaft 5 to its original position. On the contrary, when the braille for the visually impaired person is located on the right side and the medium P having the right thickness thicker than the left thickness is inserted, only the right bearing shaft 5 moves in a direction away from the fourth rotation shaft 4. In the right suspension 80, a tension is applied to return the right bearing shaft 5 to its original position.

Therefore, at any position, the braille for the visually impaired is separated by the belt 42 and the withdrawal roller 20 supported by the belt pulley 40 and the belt bearing 50 by the movement of the respective left and right bearing shafts 5. There is a constant play between the two, and after passing all of the problem medium (P) through the play, the independent of the left and right suspensions 80, which are respectively installed on the pair of bearing shaft (5) in a separated state The left and right bearing shafts 5, that is, the left and right belt bearings 50, are returned to their original positions by the in-autotension function.

Reference numerals "60" and "70", which are not described in the drawings, respectively indicate 'feeding bearings' to assist the conveyance of the medium P. FIG.

On the other hand, the above-mentioned auto-tension function to automatically pass through all of the media (P) that caused the change in thickness, so that even if the change in the thickness of the medium (P) take out roller 20 and the separation belt ( The possibility of jam occurrence at the contact portion of 42) can be completely eliminated.

In addition, although not shown in the drawings, the present invention may further include an optical sensor at a predetermined position for monitoring a driving operation of the motor (and thus rotation) of the shaft. Such an optical sensor is preferably provided in a cassette in a hall sensor method which is not affected by dust in order to prevent the influence of the sensor due to banknote dust, which has a much better effect than the encoder method used in the prior art. .
