Description

Media separation device

The present invention relates to a media separation device, and more particularly, to a media separation device used in an automatic teller machine or the like.

Automated Teller Machine (ATM), as is well known, is a device that assists customers to view financial services such as deposit, withdrawal, or utility bill payment, regardless of location and time, without the assistance of a bank employee.

Such automatic teller machines receive banknotes or checks through the deposit and withdrawal unit in the case of a deposit transaction according to a financial transaction with a customer, separate and return them in sheets, load them in a temporary storage unit, and return them to a cassette when a financial transaction is established, and then withdraw. In the case of transactions, the bills or checks loaded in the cassette are separated and returned in sheets and discharged through the deposit and withdrawal unit.

At this time, in the automatic cash teller machine, a deposit/withdrawal unit, a temporary storage unit, and a cassette in which media (banknotes or checks) are loaded are provided with a media separating device for separating and conveying the loaded media one by one.

In general, the media separation device should be configured to ensure perfect mechanical reliability when withdrawing bills or checks. An example of such a media separation device is disclosed in Utility Model Registration No. 199800 filed and registered by the present applicant ( See Patent Document 1).

According to this utility model registration, a first rotation shaft and a second rotation shaft are horizontally installed at the top and bottom of the frame, a third rotation shaft is horizontally installed between the first rotation shaft and the second rotation shaft, and the second rotation shaft is installed horizontally. 2 A media separating device is provided with a fourth rotation shaft horizontally installed at the rear of the rotation shaft, and a motor for rotating the first to third rotation shafts as constituting means.

In general, a separation roller of a size specified according to the thickness of the media must be used. As a result, the size of the separating roller changes frequently. For example, the thickness of the bill is very different for each country or for each type of bill, and as shown in FIG. 1, the position of the Braille for the visually impaired may be different. In this case, the gap method or the overlap form The media separation device of is troublesome to individually manage the separation roller according to the thickness of the bill. In addition, since the size of the separation roller is determined and used according to the thickness of the medium, there is a high risk of damage or jamming of the medium in the gap portion (overlap) when a medium exceeding the specified thickness is input.

Accordingly, the present invention is to solve the above problems, and there is no need to replace the rollers according to the difference in thickness of the bills by each country or by type of bills or the position of the braille for the visually impaired, and also to avoid damage and jams of the media. It is an object of the present invention to provide a device for separating media that can be solved.

A pair of take-out rollers; Separate each sheet by supporting the lower end of the medium, provided to correspond to the pair of take-out rollers, the fourth rotation shaft positioned at the rear of the second rotation shaft and the fourth rotation shaft in the circumferential direction of the pair of take-out rollers. A pair of separation belts positioned below the rotation shaft and supported by a pair of bearing shafts slidable in a direction away from the fourth rotation shaft; When the medium is folded in half, or a number of different media are inserted between these folded gaps, or when media of different thicknesses on the left and right due to different thicknesses or the location of the braille for the visually impaired are inserted, the withdrawal roller is used. When there is a change in the thickness of the conveyed medium, a predetermined elastic force is used between the fourth rotation shaft and the pair of bearing shafts to prevent jams from occurring at the contact portion between the take-out roller and the separation belt, respectively. It characterized in that it comprises a pair of suspensions that are separately installed so as to independently perform the auto tension function.

The media separating device according to the present invention does not require replacement of rollers according to differences in thickness of bills by country or by type of bills or position of braille for the visually impaired, and is configured to eliminate concerns about damage and jams of media. Let it be the technical point. That is, even if a thickness change occurs in the input medium, it is an important technical feature that the separation and feeding of the medium are not affected at all.

As shown in the drawing, the media separating device of the present invention is a device that separates a predetermined medium (P) such as a bill or a check from a cassette and transfers it in the conveying direction. It includes a pair of take-out rollers 20 and a transfer roller 25 that rotates in the same direction in connection with the rollers 10 and the friction rollers 10 and transfers the medium P, and is basically a utility model registered. It has the same operating configuration as No. 198800. The friction rollers 10 are means for initiating the transfer of the medium P, and at least one pair is installed at the center of the first rotating shaft 1 located above the device frame (not shown), and each friction roller 10 ) At least a part of the circumferential surface is made of the friction pad 12. A pair of withdrawal rollers 20 are provided with the pair of friction rollers 10 in the center of the second rotation shaft 2 installed horizontally with the first rotation shaft 1 at the bottom of the first rotation shaft 1. It is installed correspondingly, and at least part of the circumferential surface of each withdrawal roller 20 is made of a withdrawal pad 22. A pair of take-out rollers 20 and a transfer roller 25 are installed on the second rotation shaft 2, and the transfer roller 25 is spaced apart at a predetermined interval between the pair of take-out rollers 20 and outside the It is installed as.

In the media separating apparatus of the present invention, a configuration 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 one by one by supporting the lower end of the media P. Such a pair of separation belts 42 are installed in correspondence with the take-out roller 20, and the fourth rotation shaft 4 located at the rear of the second rotation shaft 2 and the pair of take-out rollers 20 It is supported by a pair of bearing shafts 5 located below the fourth rotational shaft 4 in the circumferential direction and slidable in a direction away from the fourth rotational shaft 4. The bearing shaft 5 slides according to the tension of the separation belt 42.

A pair of belt pulleys 40 corresponding to the take-out rollers 20 of the second rotation shaft 2 are provided on the fourth rotation 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. The pair of separating belts 42 on the pair of belt pulleys 40 and belt bearings 50 have a constant tension on the left and right sides, preferably in the direction of rotation of the take-out roller 20, that is, conveyance It is installed in an inclined state with a certain slope in the direction of the furnace.

The fourth rotation shaft 4 is connected to a drive shaft or a third rotation shaft (not shown) linked thereto by a motor (not shown), and preferably, first and second rotation shafts 1 linked to the third rotation shaft. It rotates 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 between the separation belt 42 and the take-out roller 20 driven by the belt pulley 40 on the fourth rotation shaft 4 The face-to-face direction is opposite to each other. For example, when the withdrawal pad 22 of the withdrawal roller 20 proceeds in the conveyance direction of the medium P, the surface of the separating belt 42 proceeds in the direction opposite to that of the cassette.

The separation belt 42 is basically preferably rotated at a slower speed than the take-out roller 20. In this case, the second rotation shaft 2 on which the take-out roller 20 is installed and the fourth drive shaft of the separation belt 42 The rotation ratio of the rotation shaft 4, that is, the rotation ratio between the withdrawal roller 20 and the belt pulley 40 may be set to 100:1 to 200:1, preferably 152:1.

According to this configuration, when the medium P is taken out from the cassette, the friction roller 10 and the take-out roller 20 rotate while the medium P proceeds in the direction of the conveyance path. The friction pad 12 and the withdrawal pad 22 transfer one medium (P) in one rotation of each roller (10, 20), and the first medium (P) located at the top of the cassette is a friction pad. It is in close contact with the surface of the withdrawal pad and is conveyed in the direction of the conveyance path. On the other hand, while the first medium (P) is withdrawn, the separation belt 42 proceeds at a lower speed than the withdrawal roller 20 toward the cassette side in a direction opposite to the direction in which the withdrawal pad 22 proceeds, and the first medium P Push the second medium (P) below and the remaining medium (P) toward the cassette side. In this way, the remaining media P including the second media P are separated by the separating belt 42 driven in the reverse direction and are not transferred in the direction of the conveyance path, thereby achieving a more stable media P separation.

On the other hand, in the present invention, the configuration of the intermittent rotational motion mechanism and the one-way bearing mentioned in the prior art is not required, and in particular, the belt pulley 40 is configured to rotate at a lower speed than the withdrawal roller 20 by using the difference in rotation ratio. In this case, it is possible to prevent uneven wear due to the installation of one-way bearings in the prior art.

On the other hand, the media separating apparatus of the present invention, when there is a change in the thickness of the media P transferred to the withdrawal roller 20, for example, the first media P is folded in half or a plurality of these folded gaps The draw roller 20 and the separating belt 42 have different thicknesses or different thicknesses due to the location of the braille for the visually impaired. It includes a configuration capable of solving the problem of jamming in the contact part.

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

The pair of suspension devices 80 slide in a direction away from the fourth rotation shaft 4 in order to eliminate 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 independently restores the bearing shaft 5 to its original position when moving.

Specifically, the pair of suspension devices 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.

The hinge bracket assembly 84 has both side ends fastened to the fourth rotation shaft 4 and the bearing shaft 5, and may be composed of first and

second hinge brackets

82 and 83 that are hinged to each other.

The compression spring assembly 85 elastically supports the hinge bracket assembly 84 from the outside, and is contracted and relaxed according to the clearance of the separation belt 42.

For example, when a change in the thickness of the medium P occurs, such as when the first medium P is folded in half as described above, or a number of other media 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 rotation shaft 4, that is, in an outward direction, in which case the suspension 80 In ), tension is applied to return the bearing shaft 5 to its original position.

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

When a medium (P) whose left thickness is thicker than the right thickness is input because the braille for the visually impaired is located on the left, only the left bearing shaft (5) moves in a direction away from the fourth rotation 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 is located on the right side and the medium P whose right thickness is thicker than the left thickness is input, only the right bearing shaft 5 moves in a direction away from the fourth rotation shaft 4, at this time In the right suspension device 80, tension is applied to return the right bearing shaft 5 to its original position.

Therefore, the separation belt 42 and the take-out roller 20 supported by the belt pulley 40 and the belt bearing 50 by the movement of each of the left and right bearing shafts 5 regardless of the position of the braille for the visually impaired There is a certain gap between the gaps, and after passing all of the problematic media (P) through this gap, the left and right suspension devices 80 installed on the pair of bearing shafts 5 in a separate state are independent. 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-auto tension function.

In the drawings, reference numerals "60" and "70", which are not described, denote'transfer bearings' that assist the conveyance of the medium P, respectively.

On the other hand, the above auto-tension function allows all the media (P) that caused the thickness change to be automatically passed through and recovered. Therefore, even if the thickness of the media (P) is changed, the withdrawal roller 20 and the separation belt ( It can eliminate the risk of jam at the contact point of 42).

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

On the other hand, although the media separation device according to the present invention has been described according to a limited embodiment, the scope of the present invention is not limited to a specific embodiment, and within the range obvious to those of ordinary skill in the art. It can be implemented with alternatives, modifications and changes of branches.

Accordingly, the embodiments disclosed in the present invention and the accompanying drawings are not intended to limit the technical idea of the present invention, but to explain, and the scope of the technical idea of the present invention is not limited by these embodiments and the accompanying drawings. . The scope of protection of the present invention should be interpreted by the following claims, and all technical ideas within the scope equivalent thereto should be interpreted as being included in the scope of the present invention.
