The tributary processing apparatus according to the present invention is an apparatus for processing a tributary containing paper currency, and may be a paper currency discriminating apparatus for counting inputted paper currency and discriminating each paper currency, but the present invention is not limited to this, And the like. Hereinafter, a branch processing apparatus for transferring and discriminating and processing the inputted bill will be described as an example. First, the first embodiment will be described.

First Embodiment

The tributary processing apparatus according to the first embodiment largely includes a drive control section for performing software operation of the apparatus and a hardware apparatus section for transferring the actual tributary flow.

1 includes a control unit 100, a main roller driving unit 110, and a transport roller driving unit 120. The main roller driving unit 110 and the transport roller driving unit 120 are the same as those shown in FIG. The control unit 100 controls the main roller driving unit 110 to provide a driving force to the main roller 11 and controls the feeding roller driving unit 120 to provide a driving force to the feeding roller 20, So as to provide a driving force to the reverse roller 30. The control unit 100 may control the reverse roller driving unit 130 to provide an independent driving force to the reverse roller 30. The reverse driving unit 130 may include a reverse roller driving unit (not shown) . The control unit 100 drives the main roller 11 to control the main feed unit 10 to feed the fed tributary at a first speed and drives the feed roller 20 to drive the main The feeder 10 is controlled so as to feed a tributary stream at a second speed which is larger (faster) by a predetermined multiple of the first speed, which will be described in more detail below.

As shown in Figs. 2 and 3, the tributary supplied and supplied from the hopper 50 is transported by the main feed section 10 at a first speed. The main feed section 10 is positioned on the main path for feeding the fed tributary to the discrimination section (not shown) at the trailing end, and feeds the tributary flow. In this embodiment, as an example of the main feed portion, a conveying means including a belt portion, a main roller, and an idle push roller is exemplified as shown in Figs. 3 and 5. However, according to the embodiment, (O-rings), rollers (front friction rollers) disposed around the outer circumference of the friction surface, and the like can be employed. have.

The main feed section 10 includes a belt section 13, a main roller 11 and a first idle push roller 12. [ The belt portion 13 is in contact with the branch flow to move the belt portion 13, and the main roller 11 contacts the belt portion 13 to rotate the belt portion 13 while rotating. Then, the first idle push roller 12 rotates together with the movement of the belt portion 13. The first idler push roller 12 is designed to have an elastic force in a vertical direction by a spring structure so that the first idler push roller 12 presses the belt portion 13 in the upward direction as shown in Figs. 3 and 4, It is possible to maintain the overlapping distance between the reverse rollers 30 within a certain range so that the reverse roller 30 can perform its role (e.g., sheet separation) The normal input of the tributary shall be possible regardless of The first idle push roller 12 is movable up and down in the right and left directions, and skew of the branch flow can be prevented by the contact force with the branch flow.

The conveying roller 20 is provided on the upper side of the main roller 11 or on the conveying path of the main roller 11 to convey the tributary discharged through the main feed portion 10. At this time, the control unit 100 controls the conveying roller driving unit 120 to rotate the conveying roller 20 to convey the tributary at the second speed. Here, the second speed refers to a speed that is larger by a certain multiple than the first speed, which is the speed at which the main feed section 10 feeds the tributary. In addition, the transport roller driver 120 may rotate the transport roller 20 to transport the tributary at a speed higher than the second speed.

In many cases, a gap may not be constantly maintained between tributaries (bills) charged depending on the size of the bills, the state of the bills, the state of charging the bills, the state of assembling the apparatus, and the like. If the spacing between bills is not kept constant and thus the interval between the bills becomes excessively narrow (shortened), errors may occur in the discrimination unit (not shown) at the subsequent stage because the bills can not be accurately discriminated .

In the present embodiment, the tributaries discharged from the main feed section 10 are continuously discharged without a gap between the branch flows in the steady state. In this case, it means that there is no gap between the front bills and the back bills at all, meaning that the front is discharged and the back is discharged immediately. That is, the interval may be selected within the range of 0 mm to several tens mm depending on the operating environment or design intention, and ideally, it is preferably 0 mm to several mm. A feed roller 20 is provided in the vicinity of the discharge portion of the main feed portion 10, particularly the upper side of the main roller 11, in order to secure a predetermined gap between the feeds, Is larger than the feed rate of feed by the main feed section (10) by a predetermined multiple. That is, if the second speed by the conveying roller 20 is set to be twice as fast as the first speed by the main feed section 10, for example, the interval between the discharged tributaries becomes shorter than the interval between the reverse roller 30 and the conveying roller 20. [ (20). The minimum distance between the bills secured by the conveying roller 20 can be obtained as follows.

Bills distance = (ratio of the second speed to the first speed) * (distance between the transport roller and the reverse roller)

The ratio of the second speed to the first speed and the distance between the conveying roller and the reverse roller are set so that the second speed is larger than the first speed by a predetermined multiple, A gap is generated between the leading ends, and a proper branch interval for normal discrimination is secured in the discriminating portion (not shown). Here, the speed ratio between the second speed and the first speed may be variously set according to conditions and settings of the corresponding feeder processing apparatus.

On the other hand, the reverse roller 30 provides a frictional force to the branch flow in a direction opposite to the direction in which the branch flow is fed. As shown in FIGS. 2 to 4, and particularly in FIG. 4, the reverse roller 30 includes a first rotating portion 31 and a second rotating portion 32. The first rotating part 31 feeds the tributary through the interaction with the belt part 13 of the main feed part 10. [ The second rotating portion 32 rotates in a direction opposite to the first rotating portion 31 and provides frictional force to the tributary in a direction opposite to the direction in which the tributary flow is transmitted. The control unit 100 drives the conveying roller driving unit 120 or a separate reverse roller driving unit (not shown) to rotate the second rotating unit 32 to provide a frictional force to the tributaries. It is possible to prevent the occurrence of a discrimination error by separating each banknote. A friction material such as rubber or urethane may be used for the outer circumferential portion of the second rotation portion 32.

7 is a reference view showing another example of the arrangement relationship between the main feed section and the reverse roller in the first embodiment. As shown in Fig. 7, when the second rotation section 32 of the reverse roller 30 is in the positive And the first rotation part 31 may be applied in the form of a wide rotation part therebetween. In this case also, the first rotary section 31 feeds the branch flow through the interaction with the belt section 13 of the main feed section 10, and the second rotary section 32 rotates in the direction opposite to the first rotary section 31 And providing frictional force to the tributary in the direction opposite to the direction in which the tributary is transported.

As shown in FIG. 4, the belt portion 13 of the main feed portion 10 may include a plurality of belt members disposed apart from each other and capable of continuously feeding bills. Here, belts may include all kinds of belts or similar belts, hereinafter referred to simply as belts. The second rotating portion 32 of the reverse roller 30 may include one or more rollers located opposite to the space between the plurality of belts. That is, when the belt portion 13 includes three belts as shown in FIG. 4, two rollers (second rotating portions) can be positioned at positions corresponding to spaces between the belts. By doing so, it is possible to effectively provide a frictional force to the branch flow in the direction opposite to the advancing direction on the main path through which the branch feed is fed by the main feed section 10. [ Further, the overlapping distance between the reverse roller 30 and the belt portion 13 can be always kept constant.

The belt portion 13 of the main feed portion 10 includes one wide belt having a groove formed at a position opposite to the second rotation portion 32 of the reverse roller 30 can do. In addition, the main feed unit 10 may include rollers disposed apart from each other and capable of continuously feeding bills.

Second Embodiment

In the paper feed processing apparatus according to the second embodiment, the conveying roller 20 is spaced apart from the main roller 11 by a certain distance, and is disposed on the conveying path in the rear of the main roller 11. [ The paper feed processing apparatus further includes a second idle push roller 40 that presses the branch stream through interaction with the feed roller 20. [

Here, when the conveying roller 20 is rotated by the conveying roller driving part 120, the second idle push roller 40 rotates together with the branch flow passing therebetween. As a result, the tributaries are transported at a second speed which is a predetermined multiple of the first speed by the main feed section 10, and the effect is the same as in the first embodiment.

In addition, in the second embodiment, the second idler push roller 40 is formed so that the left and right sides thereof can be moved up and down by the elasticity (can be individually swung up and down). If the second idle push roller 40 is skewed and skewed, the second idle push roller 40 can appropriately control the tractive force with the tributary flow at the left and right sides of the roller to prevent the skew of the tributary. That is, the left and right second idle push rollers 40 can be individually moved up and down so that the timing at which the corresponding tributary is accelerated by the feed roller 20 through the tractive force with the tributary can be controlled to prevent skewing of the tributary . For this, the control unit 100 senses the leading end of the tributary discharged from the main feed unit 10 through a separate sensor (not shown) to determine the degree of skew of the tributary, and controls the feed roller driving unit 120 To adjust the pressing timing of the second idle push roller 40 with respect to the conveying roller 20.

For reference, in this embodiment, as shown in FIG. 5, the conveying roller 20 is provided below the branch conveying path and the second idler push roller 40 is installed on the conveying roller 20. However, according to the embodiment, The position may be reversed.

5, the reverse roller 30 is located at the front end of the main roller 11 on the conveying path, but may be located near the upper side of the main roller 11 as shown in FIG.

As described above, the tributary processing apparatus according to the present invention ensures the minimum interval between the branch tributaries to be ensured for discrimination of the respective branch tributaries when the branch tributaries including bills are continuously inserted, Thereby reducing errors and improving accuracy.

While the invention has been shown and described in detail in the foregoing description, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art, Of the right.
