The present invention relates to a media separation device of a financial automation device that can be separated.

In general, automatic teller machines (ATMs) can provide basic financial services such as cash and check deposits and withdrawals by using a card or bankbook without a bank employee, regardless of time and place. It is an automated device. Recently, the use of automatic teller machines has been increasing in convenience stores, department stores, and public places as well as financial institutions such as banks.

The automated teller machine can be divided into withdrawal machine, depositor and withdrawal machine according to the withdrawal and withdrawal.In recent years, the automated teller machine has various uses such as cash withdrawal, check deposit, withdrawal, bankbook payment, giro fee payment, ticket release etc. Is being used.

A media transport path for transporting paper media, such as cash, checks, tickets, gift certificates, etc., is formed inside the automated teller machine. Typically, the media transport path consists of a combination of a plurality of rollers and belts. The structure of the media transport path is not only complicated but also the overall size of the media transport path is large. Therefore, there is a limit in increasing the conveyance path of the paper medium, and jams occur frequently in the paper medium. The withdrawal or deposit operation of the paper medium is very complicated.

In particular, jams are frequently generated in the process of drawing out the paper media stored in the media storage unit one by one, and two paper media may be abnormally picked up from the media storage unit.

According to an embodiment of the present invention, a financial automation device capable of separating the two paper media picked up from the media storage unit from the feed roller unit and the gate roller unit by rotating the gate roller unit at a predetermined angle according to the rotation angle of the pickup roller unit. It provides a media separation device.

In addition, an embodiment of the present invention provides a media separation device of an automated teller machine capable of preventing uneven wear of the gate roller by rotating the gate roller at a predetermined angle.

According to an embodiment of the present invention, there is disclosed a media separating apparatus of an automatic teller machine that separates a paper medium from a media storage unit and provides the same to a media conveying unit.

That is, a main body provided between the medium storage part and the medium conveying part, a pickup roller part provided at the main body so as to be disposed at a position corresponding to the medium storage parts, and picking up the paper media one by one from the medium storage parts, the A feed roller part for feeding the paper medium picked up by a pickup roller part, a gate roller part rotatably disposed in a position opposite to the feed roller part so that the paper medium is transferred between the feed roller part, and the And a reverse rotation mechanism provided in the gate roller unit and the pickup roller unit and rotating the gate roller unit by a predetermined angle in a reverse direction of the paper medium separation direction by receiving the rotational force of the pickup roller unit. to provide.

When the gate roller portion is reversely rotated in a direction opposite to the conveying direction of the paper medium as described above, the two paper media entering between the feed roller portion and the gate roller portion are mutually connected by the feed roller portion and the gate roller portion. It may be fed in the other direction. Accordingly, the two paper media may be separated in different directions by the feed roller and the gate roller, and only the paper media fed in the forward direction by the feed roller is one of the pinch rollers. Can be transferred to the negative.

The gate roller part may be provided in the main body so as to be rotatable only in the reverse direction of the paper carrier. That is, the gate roller portion may be arranged in a structure that can not be rotated in the direction of conveying the paper medium. To this end, the gate roller portion and the main body may be provided with a one-way bearing for rotatably supporting the gate roller portion only in the reverse direction.

The reverse rotation mechanism may rotate the gate roller part at a predetermined angle whenever the pickup roller part is rotated at a predetermined angle. Since the gate roller portion is reversely rotated at a predetermined angle by the reverse rotation mechanism according to the set rotation angle of the pickup roller portion, all parts of the gate roller portion may be rubbed with the paper medium. Accordingly, it is possible to prevent uneven wear of the gate roller portion due to friction with the paper medium. Uneven wear of the gate roller may be a cause of jams generated in the media separation device.

On the other hand, the reverse rotation mechanism may also perform a function to prevent any rotation of the gate roller portion. That is, the reverse rotation mechanism may restrain the reverse rotation of the gate roller portion at an arbitrary angle regardless of the rotation angle of the pickup roller portion. For example, in the state in which the operation of the reverse rotation lever is stopped, the first reverse rotation gear cannot be rotated in the reverse direction by the second reverse rotation gear, so that the gate roller portion also cannot reverse rotation.

The reverse rotation mechanism may include a first reverse rotation gear formed at the gate roller portion, a reverse rotation lever provided with a second reverse rotation gear coupled to the first reverse rotation gear at one end thereof and rotatably provided at the feed roller portion; And a reverse rotation cam that is formed in the pickup roller portion and selectively interferes with the other end of the reverse rotation lever such that the gate roller portion is reversely rotated by the reverse rotation lever whenever the pickup roller portion is rotated at a predetermined angle. can do. The reverse rotation mechanism may further include an elastic member provided between the reverse rotation lever and the main body to provide an elastic force to the reverse rotation lever in a direction in which the other end of the reverse rotation lever is in close contact with the reverse rotation cam. Can be.

Therefore, when the reverse rotation cam is rotated together with the pickup roller unit, the reverse rotation lever may be rotated by the reverse rotation cam, and the first reverse rotation gear may be rotated in the reverse direction by the reverse rotation lever. The gate roller part may be rotated together with the first reverse rotation gear.

Meanwhile, a one-way bearing may be provided between the first reverse rotation gear and the gate roller part such that the rotational force of the first reverse rotation gear is transmitted only in the reverse rotation direction of the gate roller part. Therefore, when the reverse rotation lever rotates the first reverse rotation gear in the reverse rotation direction, the gate roller portion may also be reversely rotated together with the first reverse rotation gear. On the other hand, when the reverse rotation lever rotates in the direction of forward rotation of the first reverse rotation gear, the first reverse rotation gear is forward rotated by the second reverse rotation gear, but the first reverse rotation gear The gate roller part is idle by the way bearing so that the gate roller part does not rotate.

The reverse rotation cam may include a lever guide part formed in the pickup roller part and forming a space in which the other end of the reverse rotation lever is disposed between the main body, and a portion facing the main body of the lever guide part. It may be provided with a cam portion formed in a polygonal, oval, or a cross-sectional shape provided with a projection on a portion. Therefore, the other end of the reverse rotation lever and the cam part may be stably maintained between the main body and the lever guide part. In addition, the timing and the number of times the reverse rotation of the gate roller portion can be easily adjusted by only changing the shape of the cam portion.

In the media separating device of the automatic teller machine according to the embodiment of the present invention, since the gate roller part is reversely rotated in a direction opposite to the conveying direction of the paper medium at a predetermined angle according to the rotation angle of the pickup roller part, it enters the feed roller part and the gate roller part. The two sheets of paper can be separated easily. Therefore, the separation performance of the media separation device can be further improved. In addition, since only a single sheet of paper passes through the feed roller and the gate roller, it is possible to prevent the occurrence of jams due to the two sheets of paper and the withdrawal and withdrawal errors of the paper. The time and operation for processing them can also be reduced.

In addition, in the media separating apparatus of the automated teller machine according to the embodiment of the present invention, since the gate roller portion is reversely rotated at a predetermined angle every time the pickup roller portion is rotated at a predetermined angle during the operation of the media separating apparatus, the media separating apparatus is separated from the media storage portion. It is possible to prevent the paper media from contacting only part of the gate roller portion. Therefore, it is possible to prevent uneven wear of the gate roller part due to friction with the paper media, and to prevent jams and deterioration of separation performance of the paper medium due to uneven wear of the gate roller part.

First, when the media storage unit 111 is mounted in the case 110 of the automatic teller machine 100, the paper media P stored in the media storage unit 111 are pick-up rollers 140 of the media separation device 120. Close to) At this time, as the paper medium P is in close contact with the pickup roller unit 140, the pickup roller unit 140 is linearly moved at a predetermined distance toward the rear.

If the paper media P stored in the media storage 111 are not arranged in parallel with the pickup roller rotation shaft 142 but obliquely in a specific direction, the pickup roller rotation shaft 142 is an intermediate to which the drive belt 186 is connected. The angle can be pivoted on a horizontal plane about the portion. Therefore, even if the paper media P to be picked up inside the media storage 111 is arranged obliquely, the contact area between the paper media P and the pickup roller 144 can always be maintained in an optimal state. Therefore, the pickup performance of the pickup roller portion 140 can be sufficiently secured, and the jams generated during the pickup of the pickup roller portion can be reduced.

2 to 6, when the pickup roller driver 180 is driven, the pickup roller unit 140 is driven by the driving force of the pickup roller driver 180. That is, when the driving motor 184 of the pickup roller driving unit 180 is driven, the driving shaft 182 is rotated by the driving force of the driving motor 184, and the driving belt 186 coupled to the driving shaft 182 is driven. . The pickup roller rotating shaft 142 of the pickup roller unit 140 is rotated by the drive belt 186, and the pickup roller 144 is rotated together with the pickup roller rotating shaft 142. Therefore, the paper medium P in close contact with the pickup roller 144 may be picked up in the rotational direction of the pickup roller 144 in the media storage 111 by the frictional force with the pickup roller 144. At this time, the rotational speed of the pickup roller 144 may be adjusted very quickly and simply by only adjusting the ALPM of the driving motor 184.

As described above, the paper medium P picked up by the pickup roller unit 140 enters the feed roller unit 150 and the gate roller unit 160 and then the pinch roller unit 170 by the feed roller unit 150. ), The paper medium P fed by the feed roller unit 150 is forcibly transferred to the guide path of the main body 130 by the pinch roller unit 170. Thereafter, the paper medium P may be transferred to the carriage 113 or the medium recovery transfer unit 115b through the medium transfer unit 112 connected to the guide path of the main body 130.

Meanwhile, when the drive shaft 182 of the pickup roller driver 180 is rotated, the reverse rotation cam 196 may be rotated together with the drive shaft 182, and the reverse rotation lever 194 may be rotated by the reverse rotation cam 196. The operation can be adjusted at set intervals. That is, the reverse rotation lever 194 may be rotated by the reverse rotation cam 196 whenever the pickup roller 140 is rotated at the set angle.

When the reverse rotation lever 194 is rotated as described above, the first reverse rotation gear 192 may be rotated in the reverse direction A by the second reverse rotation gear 195 of the reverse rotation lever 194, and the gate The roller unit 160 may be rotated in the reverse direction A together with the first reverse rotation gear 192. On the other hand, when the reverse rotation lever 194 returns to the initial position, the first reverse rotation gear 192 may also be rotated in the forward direction B by the second reverse rotation gear 195 of the reverse rotation lever 194. However, since the first reverse rotation gear 192 is idle by the one-way bearing 193 on the gate roller rotation shaft 162, the gate roller 160 is not actually rotated.

When the gate roller 160 is rotated in the reverse direction A, the paper contacted with the gate roller 160 of the two paper media P entered between the feed roller 150 and the gate roller 160. The medium P does not pass through the feed roller part 150 and the gate roller part 160, and the paper medium P contacted with the feed roller part 150 is the feed roller part 150 and the gate roller part 160. Can pass through

Therefore, two sheets of paper medium P entering between the feed roller 150 and the gate roller 160 may be separated due to the reverse rotation of the gate roller 160. In addition, since the gate roller 160 is continuously rotated according to the rotational angle of the pickup roller 140, the gate roller 164 may be in uniform contact with the paper medium P, and the wear of the gate roller 164 may be caused. Can be prevented beforehand.

In addition, the reverse rotation mechanism 190 may also perform a function of preventing any rotation of the gate roller 160. That is, when the gate roller 160 is arbitrarily reversed, the reverse rotation operation of the gate roller 160 may be constrained by the reverse rotation mechanism 190. For example, when the operation of the reverse lever 194 is stopped, the first reverse gear 192 cannot be rotated in the reverse direction A by the second reverse gear 195, so that the gate roller part ( 160 can be prevented from arbitrarily reverse rotation.

Meanwhile, the feed roller unit 150, the pinch roller unit 170, and the media conveying unit 112 are driven together by the main driver 117 of the automated teller machine 100. That is, the feed roller unit 150, the pinch roller unit 170, and the medium conveying unit 112 are structured to be interlocked by the driving force of the main driver 117. On the other hand, the pickup roller unit 140, the gate roller unit 160, and the reverse rotation mechanism 190 are driven together by the driving force of the pickup roller driving unit 180. That is, the pickup roller portion 140, the gate roller portion 160, and the reverse rotation mechanism 190 are substantially controlled by the drive motor 184 of the pickup roller driver 180.
