The present invention relates to a one-way power transmission device used for a conveying path of an ATM, and more particularly, receives a rotational force from a gear connected to a drive shaft of another conveying path portion in which a conveying direction is switched by one motor in an ATM. Drives the conveying path, but always transfers the bill in a certain direction irrespective of the conveying direction of the other conveying path part, transfers the bill in the desired direction in each part without using additional motor, simplifies the overall structure and lowers the manufacturing cost The present invention relates to a one-way power transmission device used for a return path of a cash machine.

Cash Dispenser (CD) is included in Automated Banking Machine, which is a device designed to provide most services except counseling services promptly and conveniently without regard to financial services. And ATM (Automated Teller Machine), which are developed and used in the early stages for the computerization of financial services, are devices that can automatically withdraw cash only. In addition to the payment function is also a device equipped with a deposit function.

Such automatic teller machines are installed in convenience stores and public places in addition to banks to provide customers with convenient financial services at banks or other financial institutions, so that customers can freely withdraw cash using their own cash service cards or credit cards. As a device, the banknotes put by the user at the time of deposit should be separated by a separator and transferred to the conveying path, the authenticity of the transferred banknotes must be determined, and the banknotes determined to be unacceptable must be rejected and returned to the user. .

In addition, depending on the model, the deposit and withdrawal unit of the automatic teller machine also has a function of storing the unacquired banknotes in the lost collection section when the user does not acquire the banknotes rejected at the time of deposit or the banknotes accumulated in the storage section at the time of withdrawal. In addition to the above, it is possible to configure a cash dispenser to which various configurations are added according to functions such as a card processing unit and a bankbook processing unit.

These ATMs are unmanned devices that bankers do not directly conduct bank transactions, so there are many security problems, and because ATMs are always stored a lot of cash, it is always easy to be a target of crime.

For this reason, various security methods are used or suggested to prevent financial accidents related to ATM machines. For example, a closed circuit camera (CCTV) is installed in a teller machine and used to identify a criminal in the event of a financial accident.

In addition, the use of safe type ATMs designed to be safer against external crushing attacks, such as drills and hammers, has been proposed, compared to conventional cabinet ATMs. Type) ATM machines have been commercialized.

5 is a side schematic view of a fourth conveying path of the safe type cash dispenser in which the one-way power transmission device of the present invention is used. This is shown in detail from the perspective of looking down the fourth conveying path shown in FIG.

Referring to FIG. 5, the operation principle of the one-way power transmission device of the present invention will be described. First, when the drive shaft 10 receiving power from the transport path driving motor 600 rotates in the counterclockwise direction (CCW), A power transmission gear set meshes with one of the gears (12 gears) directly connected to both sides of the drive shaft 10 to transmit rotational force to the first driven gear (a gear), and in this embodiment, the first power The transmission gear set is composed of gear 13 and gear 14. The first driven gear (a gear) rotates clockwise (CW), and the first driven gear (a gear) is rotated to the first gear Since the bearing coupled to the coaxial 20 is a one-way bearing for transmitting the rotational force of the first driven gear (a gear) to the first driven shaft 20 only when rotating in the counterclockwise direction (CCW), Rotation force of the drive shaft 10 is the first driven shaft 20 ) Will not be delivered. At this time, the second power transmission gear set meshes with the gear (gear 15) opposite to the gear of the drive shaft 10 to transmit the rotational force to the second driven gear (b gear), in the present embodiment the second The power transmission gear set includes only the 16th gear, and the second driven gear (b gear) rotates in a counterclockwise direction (CCW), and the second driven gear (b gear) is rotated by the first driven shaft ( Since the one-way bearing for transmitting the rotational force of the second driven gear (b gear) to the first driven shaft 20 is used only in the bearing that is coupled to 20) in the counterclockwise direction (CCW), the drive shaft 10 The rotational force of) is transmitted to the first driven shaft 20. Therefore, the first driven shaft 20 is rotated in the counterclockwise direction (CCW), so that the first driven shaft directly connected gear (gear 17) directly connected to the first driven shaft 20 is also counterclockwise (CCW). ), And the conveying roller 40 of the fourth conveying path is rotated counterclockwise by the gears 18 and 19 which are rotated in engagement with the first driven shaft direct gear (gear 7). CCW).

On the other hand, when the drive shaft 10 receives the power from the transfer path drive motor 600 rotates in the clockwise direction CW, the second power transmission gear set is one of the gears directly connected to both sides of the drive shaft 10. In conjunction with (15 gear) to transmit the rotational force to the second driven gear (b gear), in the present embodiment the second power transmission gear set consists of only 16 gear bar the second driven gear (b Gear) rotates clockwise (CW), and the bearing for coupling the second driven gear (b gear) with the first driven shaft 20 is only rotated in the counterclockwise direction (CCW). Since a one-way bearing for transmitting the rotational force of the driven gear (b gear) to the first driven shaft 20 is used, the rotational force of the drive shaft 10 is not transmitted to the first driven shaft 20. In this case, the first power transmission gear set meshes with the gear (gear 12) opposite to the gear of the drive shaft 10 to transmit the rotational force to the first driven gear (a gear). The power transmission gear set includes a gear 13 and a gear 14. The first driven gear (a gear) rotates in a counterclockwise direction (CCW), and the first driven gear (a gear) is removed. 1 The one-way bearing which transfers the rotational force of the first driven gear (a gear) to the first driven shaft 20 only when it is rotated in the counterclockwise direction (CCW) also in the bearing to be coupled to the driven shaft 20 Therefore, the rotational force of the drive shaft 10 is transmitted to the first driven shaft 20. Therefore, the first driven shaft 20 is rotated in the counterclockwise direction (CCW), so that the first driven shaft directly connected gear (gear 17) directly connected to the first driven shaft 20 is also counterclockwise (CCW). ), And the conveying roller 40 of the fourth conveying path is rotated counterclockwise by the gears 18 and 19 geared to rotate in engagement with the first driven shaft direct gear (gear 17). CCW).

FIG. 6 is a table showing rotation directions of the components of the fourth conveying path part of the safe type cash dispenser in which the one-way power transmission device of the present invention is used.

As shown in FIG. 6, it can be seen that according to the one-way power transmission device of the present invention, the first driven shaft 20 can be rotated only in one direction, regardless of which direction the drive shaft 10 rotates.

Although not shown in FIG. 5, a transfer path gate corresponding to the third branch switching unit 217 is provided on the driving shaft 10 and the first driven shaft 20, and the one-way power transmission of the present invention is performed. By using the apparatus, the first driven shaft 20, the second driven shaft 30, and the conveying roller 40 of the fourth conveying path corresponding to the portion of the fourth conveying path 214 are always in the counterclockwise direction (CCW). It can be driven.

In addition, a portion of the fourth conveying path 214 in which the one-way power transmission device of the present invention is used, the discriminating part mounted below the upper conveying mechanism 1a to remove or maintain the jam. In order to easily access 300, etc., a transport path structure including a gear 18 and 19 and a second driven shaft 30 to be rotated upwardly about the first driven shaft 20. Is installed, the frame having a sufficient rigidity is coupled to the lower portion of the conveying path structure, an elastic medium such as a spring for supporting one side of the frame when the combination of the conveying path structure and the frame is placed in a horizontal state It is installed on one side of the frame, and supports the combination of the transport path structure and the frame.

On the other hand, the one-way power transmission device used in the conveying path of the ATM machine of the present invention may be configured by using a one-way bearing in the bearing for coupling the gear 12 and the gear 15 and the drive shaft 10, in which case the Either of the first power transmission gear set or the second power transmission gear set does not rotate, and there is a fear that the drive may not be smoothly performed when the rotation direction of the drive shaft 10 is switched.

7 (a) and 7 (b) are schematic diagrams of a one-way power transmission device in a simpler form.

In FIG. 7, the shafts of the drive gear 51 and the gears 52 and 53 are fixed to the frame, whereas the shafts of the c and d gears are installed on a bracket having a triangle-like shape that supports the axes of the c and d gears. The bracket is hinged to the drive shaft 50 to form a structure in which the bracket and the c and d gears can rotate about the drive shaft 50.

When the drive shaft 50 rotates in the counterclockwise direction (CCW), the portion consisting of the c gear, the d gear and the bracket rotates in the counterclockwise direction (CCW) by the power transmission resistance of the drive gear 51 and the c gear. Gear 52 and the gear 52 is meshed bar 53 gear is rotated clockwise (CW), when the drive shaft 50 is rotated in the clockwise direction consisting of c gear, d gear and the bracket is the drive gear (51) ) And the gear d rotates clockwise (CW) by the power transmission resistance of the gear d and the gear d is engaged with the gear 53. Since the gear 53 rotates clockwise (CW), the rotation direction of the drive shaft 50 Regardless, gear 53 can always be rotated in the same direction.

This structure is very simple and inexpensive, but it is preferable to be disposed in a horizontal direction rather than a vertical direction, it is difficult to install in a place where the surrounding space is insufficient, such as a safe type cash dispenser using the one-way power transmission device of the present invention. .

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and may be variously modified or modified without departing from the technical spirit of the present invention. It is apparent to those skilled in the art that the present invention is not limited by the description of the embodiments.
