Figure 1 shows a part of the configuration of the media separation device according to the present invention, an enlarged side view showing the installation and operating state of the separation belt, Figure 2 is an enlarged plan view of a part of the configuration according to Figure 1;

The present invention provides a medium separating device that does not affect the separation and feeding of the medium even if a thickness change occurs in the introduced medium. The media separating apparatus of the present invention is a device for separating a predetermined medium (P), such as bills or checks, from the cassette one by one and transferring it in the conveying direction, the friction roller (10) for picking up and conveying the medium (P), the friction roller It includes a take-out roller 20 and a transfer roller 25 that rotates in the same direction in connection with (10) and transfers the medium P, and basically has the same operation configuration as Utility Model Registration No. 198800. The friction roller 10 is a means for initiating the transfer of the medium, and at least one pair is installed at the center of the first rotation shaft 1 positioned on the upper portion of the device frame (not shown), and the circumference of each friction roller 10 At least a portion of the surface is made of a friction pad (12). The take-out roller 20 is respectively installed in correspondence with the pair of friction rollers 10 in the center of the second rotating shaft 2 which is horizontally installed with the first rotating shaft 1 under the first rotating shaft 1. And, the circumferential surface of each withdrawal roller 20 is made of at least a portion of the withdrawal pad 22. Referring to FIG. 2, the take-out roller 20 and the transfer roller 25 are installed on the second rotary shaft 2, and the transfer roller 25 is spaced between the pair of take-out rollers 20 and outside each other. It is installed in a spaced state.

In the media separation apparatus of the present invention, a configuration is provided in which a pair of separation belts 42 are used instead of a pair of separation rollers of the prior art as means for separating each sheet by supporting the bottom of the medium. The separation belt 42 is installed to correspond to the take-out roller 20, the fourth rotating shaft 4 located at the rear of the second rotating shaft 2 and the fourth in the circumferential direction of the take-out roller 20 It is supported by a bearing shaft 5 located below the rotating shaft 4.

A pair of belt pulleys 40 corresponding to the withdrawal rollers 20 of the second axis of rotation 2 is provided on the fourth axis of rotation 4, and the belt pulley 40 is provided on the bearing axis 5. A pair of belt bearings 50 are provided. On the belt pulley 40 and the belt bearing 50, the separation belt 42 has a constant left and right tension, and preferably tilts with a constant inclination in the direction of rotation of the take-out roller 20, that is, in the direction of the conveying path. It is installed in the dark state.

The fourth rotating shaft 4 is connected to a driving shaft or a third rotating shaft (not shown) interlocked with the driving shaft by a motor (not shown), and preferably, the first and second rotating shafts 1 interlocked with the third rotating shaft 1 It rotates in the same direction as (2). At this time, the separation belt 42 driven by the belt pulley 40 on the fourth rotating shaft 4 and the surface of the separation belt 42 and the extraction roller 20 at the contact portion of the extraction roller 20 The facing directions are directed opposite to each other. For example, when the take-out pad 22 of the take-off roller 20 advances in the conveying direction of the medium, the surface of the separation belt 42 runs in the opposite direction to the cassette.

The separating belt 42 is basically preferably rotated at a slower speed than the take-out roller 20. In this case, the second rotating shaft 2 with the take-out roller 20 installed and the fourth driving shaft of the separating belt 42 The rotation ratio of the rotation shaft 4, that is, the rotation ratio of the take-off 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 withdrawn from the cassette, the friction roller (10) and the take-off roller (20) rotate while the medium (P) moves in the direction of the conveying path. The friction pad 12 and the drawing pad 22 transfer one sheet of media in one rotation of each

roller

10 and 20, wherein the first media P located at the top of the cassette is the friction pad and the drawing pad It is in close contact with the surface and is transferred in the direction of the conveying 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 in the direction opposite to the direction of the withdrawal pad (22) and the first medium (P) The second medium below and the rest of the medium are pushed towards the cassette. As described above, the rest of the media including the second medium is separated by the separation belt 42 driven in the reverse direction, so that the medium is more stable while not being transported in the direction of the transport path.

On the other hand, in the present invention, there is no need to configure the intermittent rotation movement mechanism and the one-way bearing mentioned in the prior art. In particular, the belt pulley 40 can be configured to rotate at a lower speed than the take-out roller 20 by using the above-described difference in rotation ratio. In this case, it is possible to prevent the occurrence of single wear due to the installation of the one-way bearing in the prior art.

In addition, the media separation device of the present invention, when there is a change in the thickness of the medium conveyed to the withdrawal roller 20, for example, the first medium (P) is folded in half or a number of different media is sandwiched between these folded gaps It further includes an additional configuration that can solve the problem of jam occurrence at the contact portion of the withdrawal roller 20 and the separation belt 42, such as when lifting, or when a different thickness of media is introduced.

This additional configuration may be composed of a predetermined suspension device 80 that connects a portion of the medium discharge side on the transport path and the bearing shaft 5 with a predetermined elastic force, and this suspension device 80 is a bearing shaft 5 ) To provide the auto-tension function to restore the original position. For example, when the first medium P is folded in half as described above, or when a change in the thickness of the medium occurs, such as when a number of different media is sandwiched between these folded gaps, or of very different thickness, eg For example, when a medium having a much thicker thickness is introduced, the bearing shaft 5 moves in a direction corresponding to the suspension device 80 around the fourth rotation axis 4, that is, in an outer direction, at this time, the suspension device 80 In), tension acts to return the bearing shaft 5 to its original position. Therefore, as the movement of the bearing shaft 5, a constant play occurs between the separation belt 42 and the take-off roller 20 supported by the belt pulley 40 and the belt bearing 50, and there is a problem through this play. After passing the medium, 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. Reference numerals "60" and "70" in the figure indicate 'transfer bearings', respectively, to assist the conveyance of the medium.

On the other hand, the above auto-tensioning function allows the media that caused the thickness change to be automatically passed through to be recovered, and thus, even if a change in the thickness of the media occurs, at the contact portion of the withdrawal roller 20 and the separation belt 42. Can clear up the concerns of jam occurrence.

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

Various embodiments of the present invention have been described above, but the contents described so far are merely illustrative of some of the preferred embodiments of the present invention, except that they may appear in the appended claims. It is not limited by the above. Accordingly, the present invention understands that those skilled in the same technical field can make many changes, modifications and substitutions of equivalents without departing from the technical spirit and gist of the invention within the scope set forth in the claims below.
