Abstract

PURPOSE: A medium conveyance method, a medium conveyance device and an automated teller machine including the same are provided to align a check by repetitively checking existence of skew of a check using a feed sensor and an entry sensor and by controlling a speed of a step motor. CONSTITUTION: A medium is injected into a conversion conveyance path(S11) and existence of skew of a medium is firstly detected using a pair of feed sensors located before the conversion conveyance path(S12). Secondly, existence of skew is detected using an entry sensor after entering the conversion conveyance path(S13). Existence of skew of the medium is detected using the first detection and the second detection results(S14). If judged as there is skew, a reaction speed is decelerated by decelerating a motor in a direction of entry(S15). If judges as there is no skew, a reaction speed is maintained until the medium reaches a stop sensor and the medium is conveyed to a main conveyance path by operating the motor in the reverse direction of entry(S25). The medium of which skew is judged as being present reaches the final destination of the conversion conveyance path(S16). If the medium reaches the final destination, the medium is conveyed in the opposite direction of the direction of entry by decelerating the step motor in the reverse direction(S17). Thirdly, existence of skew of the medium is detected by passing the medium reversely conveyed through the entry sensor(S18). The existence of skew of the medium after reversely conveying the medium is judged(S19). If the skew does not exist, the medium reversely conveyed is carried to the main conveyance path(S20).

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a media conveying method, a media conveying apparatus, and a financial automation device having the same, and specifically, in storing and conveying a paper medium such as a check with a front and back division, it is possible to correct the reversal of the check and to return it. The present invention relates to a medium conveying method, a medium conveying apparatus and a financial automation device having the same.

Financial Teller Machines (ATMs) have been widely used and used in financial institutions such as banks, which greatly reduce the waiting time of customers and allow customers to continue even after their financial institutions are closed. Financial transactions can be made at any time, and financial institutions can be provided with numerous benefits, such as drastically reducing service processing time and reducing manpower and cost.

As a kind of financial automation device, there is a function that can automatically process a paper medium called a check. On the other hand, the financial automation unit may include a check printer module that can print a check factor on the back of the check. In this case, it is necessary to include an additional pass for reversing the top and bottom of the reverse check on the financial automation device, that is, the reverse return path. However, there may be a case where a check reversed back and forth is loaded on a financial automation device, and in this case, when a check having a skew on the reverse conveyance path enters, jams jammed on the reverse conveyance path during the conveyance process (JAM ) Is likely to occur.

In order to solve the above-mentioned problems, the check is repeatedly checked for the presence or absence of check skew using a feed sensor and an entry sensor located on an inverted conveying path, and the check is naturally aligned by adjusting the speed of the step motor.

Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. In adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used to refer to the same components as much as possible even if displayed on different drawings. In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the difference that the embodiments of the present invention are not conclusive.

In describing the components of the embodiment of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are intended to distinguish the constituent elements from other constituent elements, and the terms do not limit the nature, order or order of the constituent elements. When a component is described as being "connected", "coupled", or "connected" to another component, the component may be directly connected or connected to the other component, Quot; may be "connected," "coupled," or "connected. &Quot;

The term 'medium' as used herein may include, for example, bills, checks, tickets, certificates, etc., and may be any of a variety of objects that are thinner than the width or length. In the present specification, for convenience of explanation, various media will be described using banknotes as examples.

On the other hand, the medium conveying apparatus described herein may be a financial automation device or a check processing apparatus, and may include at least a configuration related to the reverse conveyance path and the reverse conveyance path embedded in these devices.

1 is a schematic view illustrating some components of a media transport apparatus of the present invention. Referring to FIG. 1, the medium conveying apparatus 100 according to the present invention is located in an entry portion and a reverse conveying path 110 for conveying the inverted medium 300 to the reverse conveying path 110, and the medium 300. A pair of feed sensors 120 for detecting the presence or absence of a skew, and an entry sensor 130 positioned on the inversion conveyance path 110 and a second sensor for detecting the presence or absence of skew of the medium 300, and a medium on the inversion conveyance path 110. Step motor 150 for conveying 300 in the entry direction c or in the reverse direction d in the entry direction, if it is determined whether there is a skew of the medium, and if there is a skew of the medium 300, the step motor 150 A control unit (not shown) which controls the step motor 150 to be driven in the opposite direction to the entry direction when the medium 300 reaches the end point b of the inversion conveying path 110. It may include. The heat sensor 120 and the entry sensor 130 may constitute the sensing unit of the present invention.

The entry part may include at least a portion of the inversion transport path 110 from the portion where the inversion transport path 110 starts to the feed sensor 120.

First, when the medium 300 enters the inversion transport path 110, it may pass through the feed sensor 120. The feed sensors 120 are configured in pairs and each may be located on the path of the inverted conveying path through which the medium passes and may be located on both sides of the medium. The pair of feed sensors 110 may detect the time at which both edges of the medium pass, and compare the time difference to detect whether skew exists. Here, the presence or absence of skew of the medium is primarily detected.

Next, the medium 300 is conveyed to the reverse conveyance path 110 in the entry direction c and passes through the entry sensor passing point a and passes through the entry sensor 130. The entry sensor 130 may detect the presence or absence of skew by detecting a time for the medium to pass through the entry sensor point (a). Specifically, if the medium is not skewed, the normal passing time t0 through the entry sensor will be the length l of the medium / medium conveying speed v. However, when skew occurs in the medium, the diagonal direction of the medium is recognized as the medium length, and thus the time for passing through the entry sensor 130 becomes long.

Media pass time (t1) = skewed media length (l`) / media conveyance speed (v)

In the ingress sensor, skew has occurred when the medium passage time t1 is significantly different from the normal passage time t0, or when the medium passage time t1 is determined to deviate from the normal passage time t0 by more than a reference value. You can judge.

On the other hand, even when the skew is first detected from the feed sensor 130 and the skew is determined to exist, the direction of the medium may be normally returned in the process of conveying the medium 300 to the entry sensor 130. . In this case, skew may not be detected on the entry sensor 130. Similarly, even when it is determined that the skew does not exist by primarily detecting the skew from the feed sensor 130, skew occurs because the direction of the medium is changed in the process of conveying the medium 300 to the entry sensor 130. As a result, skew may be detected by the entry sensor 130. In addition, even though the skew is not actually generated or generated, errors may occur in the feed sensor 130 and the entry sensor 120 in which they are not detected. In the present invention, the presence or absence of skew can be accurately determined by performing the operation of detecting the skew two or more times in consideration of such an operation error in sensor operation and skew detection.

Next, when it is determined that there is skew after the end of the primary or secondary skew determination operation, the control unit decelerates the speed of the step motor 150 when passing through the entry sensor point a. For example, before passing through the entry sensor point (a), the speed of the stepper motor 150 is driven at 2000 pulses, which is the normal speed. When reaching the entry sensor point (a), the drive speed is reduced to 400 pulses. You can. By slowing down and transporting the medium in which the skew is present on the conveying path, the effect of aligning the medium misaligned with the advancing direction can be expected. That is, the skew can be naturally adjusted according to the deceleration conveyance of the medium.

Next, even if the medium 300 passes through the area sensed by the stop sensor 140, the inversion conveying path 110 is continuously decelerated and conveyed to the medium 300 until the end point b is reached.

On the other hand, the path adjusting unit 117 may be provided on the reverse conveyance path 110 in order to prevent the medium 300 from deviating or crumpling the path beyond the reverse conveyance path 110. The path adjusting unit 117 may be formed of a material such as rubber or urethane.

When the medium 300 reaches the end point b, the step motor is driven in the reverse direction d with the entry direction.

On the other hand, the skew of the medium 300 reached while decelerating to the end point (b) is sometimes corrected, but sometimes it is not. In the present invention, the media 300 having reached the end point (b) is passed through the entrance sensor 130 again without being immediately conveyed to the main transport path 200 to perform the third step of detecting skew. As described above, the third step of detecting the skew may be performed by measuring the passage time of the medium passing through the entry sensor and comparing the passage time of the normal medium as in the primary skew detection.

When it is determined that the skew does not exist as a result of the third skew detection, the step motor 150 operated in the direction opposite to the entry direction is driven as it is, and the connection portion of the intersection point 111 to the main transport path 200 is adjusted to adjust the medium. 300 can be conveyed to the main conveyance path.

On the other hand, when it is determined that the skew exists as a result of the third skew detection, the medium 300 is decelerated and conveyed in the entry direction c to reach the end point b, and then the operation of driving back in the reverse direction d is performed. By performing the repetition, it is possible to expect the effect of the medium alignment by the deceleration conveyance of the medium 300. When the medium conveyed in the reverse direction (c) passes through the entry sensor 130 again, the presence or absence of the skew can be detected again in the fourth order. It can convey to the conveyance path 200.

In this way, the media 300 can be detected and corrected in the fifth and sixth order by repeatedly traveling the medium to the entry sensor 130 and the end point b.

(A) and (b) are sectional drawing and top view for detecting the presence or absence of skew using the feed sensor mounted in the medium conveying apparatus. FIG.2 (a) shows sectional drawing of the medium conveying apparatus at the time of looking at a pair of feed sensor 120-1, 120-2 in the entry direction (-x direction) of a medium. When the medium 300 is warped or bent, the sensing time of the left feed sensor 120-1 and the right feed sensor 120-2 is different, and if the time difference exceeds the predetermined time difference, skew exists. You can judge. FIG.2 (b) shows the top view which looked at the medium conveyance apparatus. As illustrated in FIG. 2B, when the medium 300 having skew passes through the transport path 110, the sensing time of the left feed sensor 120-1 is the right feed sensor 120-2. Can be faster than the sensing time. In this case, the twisted length l of the medium 300 can be obtained using the time difference, and the twisted angle can be calculated using the length l. For example, when the length of the medium in the direction perpendicular to the conveyance path is L, the warped angle Θ may be calculated as in Equation 1 below. If this angle exceeds a predetermined angle, it may be determined that skew exists.

^{Θ = sin -1 (l / L} ) ------ formula 1

On the other hand, the operation of detecting skew using the feed sensor is not limited to that of FIG. For example, the presence or absence of skew can be detected using the difference between the left and right twist lengths or the passage time of the medium in addition to the angle of the medium.

3 is a flowchart illustrating a medium conveying method according to an embodiment of the present invention.

In step S11, the medium enters the reverse carrier path. Specifically, the medium enters a conveying path having an end point guide. When the driving of the inverted conveying path is performed by the step motor, the following description will be given centering on the entry direction of the medium.

In step S12, the presence or absence of skew of the medium is primarily detected by using a pair of feed sensors located before the inversion carrier path.

In step S13, the presence of the skew is secondarily detected by using the entry sensor after entering the inverted carrier path.

In step S14, the presence or absence of skew of the medium is detected using the results of the primary detection and the secondary detection. Judgment of the presence or absence of the skew may be performed when skew is present in both the primary and secondary detection results, when skew is detected in the primary, when skew is detected in the secondary, or in at least one of the primary and the secondary. May be determined by various logical expressions.

If it is determined in step S15 that skew exists, the conveying speed is reduced by decelerating the motor in the entry direction. The entry direction may be described as 'forward' in this specification.

On the other hand, if it is determined that there is no skew, the speed is kept as it is and conveyed until the medium reaches the stop sensor (step S25). Then, the medium is driven in the opposite direction to the entry direction to convey the medium to the main broadcasting path. Let's do it.

In step S16, the medium for which the skew is present is decelerated and conveyed to the end point of the reverse conveyance path. After reaching the end point, the medium touches the end guide (e) which is blocked in the conveying direction of the mapper, so that the part that first touches the end guide (e) due to skew can no longer be conveyed, and the other part continues to be conveyed to reach the end guide. By stopping until the skew of the media can be aligned. At this time, slowing down the speed of the conveyed medium means that, when the speed of the skewed medium is high, the part that first touches the end guide e due to the skew collides with the end guide e at a high speed so that the corresponding part is wrinkled or folded. This is to prevent. That is, even if the media without skew is conveyed at high speed and hits the end guide (e) after reaching the end point, there is no damage such that the long side of the medium evenly collides with the end guide and the medium is wrinkled or folded. When the skewed medium collides with the end point guide (e) at a high speed, the protruding portion due to the skew collides with the guide at a high speed, and the corresponding part may be wrinkled. In one embodiment of the present invention, in order to prevent the damage of the medium due to the sudden collision of the skewed medium, the medium can be aligned without slowing down the speed of conveying to the end point when the medium is skewed.

When the medium reaches the end point in step S17, the step motor is decelerated and driven in the reverse direction to convey the medium in the direction opposite to the entry direction.

In step S18, the medium conveyed in the reverse direction is passed through the entry sensor to detect whether the medium is skewed. At this time, it is possible to confirm whether or not the skew of the medium is corrected by decelerating and conveying the medium.

After returning the medium in the reverse direction in step S19, it is determined that there is a third skew. In this case, the presence or absence of skew can be determined by comparing the time that the medium passes through the entry sensor. As a result of the tertiary result, if there is skew of the medium, the medium is decelerated and conveyed in the entry direction again (S15), the end point of the inverted conveying path is reached (S16), and then the drive is decelerated in the reverse direction (S17) to the entry sensor. The operation of steps S15 to S19 of detecting the presence of skew again through the medium may be repeated. The repetition of the operation may be performed until there is no skew, and may be repeated by setting a predetermined number of repetitions.

On the other hand, if it is determined that the medium does not exist in the third place, the medium conveyed in the reverse direction is guided to the main conveying path and conveyed (S20).
