Bill transfer gate control method {METHOD FOR CONTROLLING GATE IN CONVEYANCE PATH}

The present invention relates to a bill transfer path control method, and more particularly to a control method of a gate for switching the traveling direction of the bill is installed on the bill transfer path of the automated teller machine.

In general, ATM (Automated Teller Machine) has an input unit for inputting information, a financial service menu, and a screen unit on which transaction status is displayed, and a banknote deposit and withdrawal device that allows a customer to input or receive a banknote for deposit and withdrawal transactions. It is provided, and the customer withdraws and withdraws cash through the banknote withdrawal device.

Referring to FIG. 1, a banknote depositing and withdrawing device of a financial automatic machine in which banknotes are withdrawn and withdrawn is a control unit (not shown in the drawing) that controls the entire device including the deposit and withdrawal of banknotes, and withdrawals for customers to input or receive banknotes for withdrawal and withdrawal. Part 1, a conveying path 2 through which the bills to be withdrawn and withdrawn through the deposit and withdrawal part 1 are transferred, a discriminating part 3 installed on the conveying path 2 to discriminate whether there is an abnormality of the bills, the discrimination Temporary storage unit 4 is temporarily loaded after the portion (3) is deposited, a plurality of recycling boxes (5) performing the reflux function by the withdrawal of the banknotes loaded from the customer and the loaded banknotes are withdrawn, the The reject box 6 is provided to accommodate the banknotes discriminated by the abnormal bank in the discriminating unit (3).

The conveying path 2 is provided with a gate 7 for changing the direction of bills to be conveyed. For example, when the banknote P is determined to be the reject right in the discriminating unit 3, it is sent to the reject box 6 (in the direction 2a in FIG. 2), and when it is determined to be the normal right, it is sent to the deposit and withdrawal unit 1. When sending (2b direction in FIG. 2), the gate 7 is pivoted to determine the conveying direction of the banknote P. FIG.

A sensor 8 is installed in front of the gate 7 so that when the sensor 8 detects the banknote P, a signal is transmitted to a controller (not shown) to control the operation of the gate 7. do.

The distance from the sensor 8 to the gate 7 calculates the time required for turning the gate 7 after detecting the banknote P in the sensor 8 in consideration of the transfer speed of the banknote, and then the gate 7 It is designed to prevent the bill from being transferred to the gate 7 in the state that it is not completely turned.

However, as shown in FIG. 3, even when the leading banknote P1 is normally transferred, when the trailing banknote P2 is transported in a skewed state at a predetermined angle twisted with respect to the advancing direction, it is measured by the sensor 8. Since the actual inter-note distance A is shorter than the inter-note bill distance B, since the trailing bank P2 reaches the gate 7 before the turning of the gate 7 is completed, the trailing bank P2 ) Has a problem that jam occurs at the gate.

The present invention has been made to solve the above-described problems, by determining the direction of bills in consideration of the skew angle of the bills or the distance between the leading and trailing bills to prevent the bills from jams in the gate The purpose of the present invention is to provide a bill transfer gate control method.

The present invention for achieving the above object, bill transfer path control to determine the transfer direction of bills by measuring the skew angle of the leading and trailing bills transported on the transport path and controlling the operation of the gate from the measured skew angle In the method, when the skew angle of the preceding or following banknote is greater than or equal to a preset reference angle, the preceding and following banknotes are rejected together.

In this case, even if the skew angle of the preceding or following banknote is greater than or equal to the reference angle, when the distance between the banknote of the preceding and following banknotes is greater than or equal to a preset reference distance, the transfer paths of the preceding and following banknotes are determined independently. It may be configured to control the operation of the gate.

Here, whether the distance between the banknotes of the preceding banknote and the following banknote is greater than or equal to the reference distance may be installed between the gate and the first sensor when the skew angle calculation of the trailing banknote is completed in the first sensor for measuring the skew angle. The second sensor for controlling the turning operation of the gate may be configured to compare and determine a time point of detecting the preceding banknote.

In addition, the sum of the absolute value of the skew angle of the preceding bank and the skew angle of the trailing bank may be configured to reject the leading and trailing banks together.

According to the present invention, it is possible to prevent the occurrence of banknote jams in the gate for switching the transfer direction of the banknotes has the advantage of reducing the occurrence of failure of the automated teller machine.

Referring to the accompanying drawings and the configuration and operation of the preferred embodiment of the present invention in detail.

In the present invention, the control method of the present invention can be applied to all of the gates installed on the paper money conveying path of the automatic teller machine to change the paper money conveying path.

In the following description, however, the skew angle of the banknote and the distance between the banknotes are measured by a banknote detecting sensor installed in the discriminating unit 3, and then the banknotes are measured at the gate when the banknotes correspond to a condition that jams can be generated at the gate from the measured data. The control method of changing the conveyance path of a banknote and rejecting it to the reject box 6 is demonstrated.

Referring to FIG. 4, the apparatus for implementing a bill transfer path control method according to the present invention includes a first sensor 110 for measuring a skew angle of a bill transferred along a transport path 2, and The second sensor 120, the first sensor for controlling the operation of the gate 7 when the banknote is installed between the first sensor 110 and the gate (7) for switching the transfer direction of the banknote The controller 300 which controls the operation of the gate 7 from the bill detection signal of the 110 and the second sensor 120 and the turning operation of the gate 7 are performed by the signal of the controller 300. The gate driver 400 is included.

The gate 7 is, for example, by turning up or down by the gate driver 400 made of a solenoid is to change the transfer direction of the bill.

A third sensor 200 may be additionally installed between the second sensor 120 and the gate 7 to detect whether there is a banknote remaining on the transport path 2.

In this case, the first sensor 110 is installed at the inlet side of the discriminating unit 3, the second sensor 120 is installed at the outlet side of the discriminating unit 3, and the gate 7 is the discriminating unit. On the front side of the discriminating part 3 on the basis of the banknote conveying direction in order to transfer the banknote determined in (3) to the reject ticket (for example, a banknote whose skew angle is a certain angle or more) to the reject box 6 Is installed.

A gate control method according to the skew angle of a banknote will be described with reference to FIGS. 5 and 6.

FIG. 5 (a) shows a state where the leading bank is skewed, FIG. 5 (b) shows a state where the trailing bank is skewed, and FIG. 5 (c) shows that the leading and trailing banks are skewed together. It shows the status of).

As shown in FIG. 5 (a), when the leading banknote P1 is transferred while skewing at an angle of θ, the distance A between the trailing edge of the preceding banknote P1 and the leading banknote P2. Is shorter than normal.

In this case, since the trailing bank P2 may be jammed at the gate 7, the skew angle θ of the leading bank P1 is measured by the first sensors 110a and 110b (S501). If the skew angle? Is equal to or greater than the preset reference angle (S503), the gate 7 is controlled to reject the leading banknote P1 and the trailing banknote P2 together with the reject box 6 ( S505). If the skew angle θ of the preceding bank P1 is less than the reference angle, the gate 7 is controlled such that the transfer directions of the preceding bank P1 and the following bank P2 are independently determined (S507).

A method of measuring the skew angle θ by the first sensors 110a and 110b consisting of two sensors on both the left and right sides is as follows. Since the speed at which the bill is conveyed and the distance between the two sensors 110a and 110b are determined by design, the time at which one end of the leading banknote P1 is detected by the sensor 110b on the right side and the other tip of the preceding banknote P1 If the time difference detected by the sensor 110a on the left side is measured, the skew angle θ can be calculated.

In addition, even when the trailing bill P2 is skewed as shown in FIG. 5B, when the skew angle θ is greater than or equal to a preset reference angle, the leading bill P1 and the trailing bill P2 are rejected together. The gate 7 is controlled (S501 to S507).

On the other hand, when the leading bank P1 and the trailing bank P2 are skewed together as shown in FIG. 5 (c), the skew angles θ ₁ and θ of the leading bank P1 and the trailing bank P2, respectively. Even if ₂ ) does not exceed the reference angle, a banknote jam may occur when the sum of absolute values of skew angles θ ₁ and θ _{2 of the} leading banknote P1 and the trailing banknote P2 exceeds the reference angle. Therefore, in this case, when the sum of the skew angles θ ₁ and θ ₂ of the leading bank P1 and the trailing bank P2 is greater than or equal to the reference angle, the leading bank P1 and the trailing bank P2 are rejected together. The gate 7 is controlled.

In the above case, when the distance between the banknotes and the trailing bank is sufficient by measuring the distance between banknotes, it is not necessary to reject the leading and trailing banks together with the reject box 6. Therefore, referring to FIGS. 7 and 8, a method of controlling the gate in consideration of the skew angle of the banknote and the distance between the banknotes will be described.

The skew angle of the trailing banknote P2 is measured at the first sensors 110a and 110b (S601), and the trailing banknote P1 and the trailing bank are formed by the first sensors 110a and 110b and the second sensors 120a and 120b. The distance A between the banknotes P2 is measured (S603).

In this case, when the skew angle of the trailing banknote P2 is greater than or equal to the reference angle (S605), and the distance A between the banknotes of the preceding banknote P1 and the trailing banknote P2 is smaller than the preset reference distance (S607), Since the bill jam may occur at the gate 7, the leading bank P1 and the trailing bank P2 are transferred in the same direction to control the gate 7 to reject together with the reject box 6 (S609). .

Even if the skew angle of the trailing banknote P2 is smaller than the reference angle (S605) or the skew angle of the trailing banknote P2 is greater than the reference angle, the distance between the banknotes of the leading banknote P1 and the trailing banknote P2 (A) If is greater than or equal to the reference distance (S607), since the banknote jam does not occur in the gate 7 to control the transfer direction of the leading banknote (P1) and the trailing banknote (P2), respectively (S611).

In this case, a method of determining whether the distance A between the banknotes of the leading banknote P1 and the trailing banknote P2 is greater than or equal to the reference distance will be described.

Since the distance C between the first sensors 110a and 110b and the second sensors 120a and 120b is determined, the one end of the trailing bank P2 is connected to the right sensor 110b of the first sensors 110a and 110b. Is detected and the other end of the trailing banknote P2 is detected by the left sensor 110a, the controller calculates the skew angle of the trailing banknote P2. In this case, if the tip of the leading bank P1 is detected by the second sensors 120a and 120b before the calculation of the skew angle of the trailing bank P2 is completed, the distance A between bills is determined to be within the reference distance. After the calculation of the skew angle of the trailing bank P2 is completed, when the tip of the leading bank P1 is detected by the second sensors 120a and 120b, the distance A between bills is determined to be greater than or equal to the reference distance. The gate 7 is controlled by independently determining the transfer directions of P1) and the trailing bank P2.
