BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bill recycle cassette for recycle type ATM

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reflux type input and output machine, and more particularly, to a reflux cassette for a reflux type input and output machine in which bills deposited in the longitudinal direction are temporarily stored in an integrated state and discharged again in a settling process.

ATM (Automated Teller Machine) is developed to handle new functions such as bank account opening, account transfer, balance inquiry, account book clearance, account opening, and time deposit registration. In this context, reflux ATM, which has been popularized as a next generation technology in recent years, is rapidly eroding the existing ATM market in accordance with the trend of financial automation.

Korean Prior Art Patent Publication No. 1185360 (prior art document 1) and Korean Patent Registration No. 0783181 (prior art document 2) are known as prior art documents which can be referred to in relation to banknote deposit and withdrawal, which is a main constituent of the reflux type ATM.

The prior art document 1 discloses a bill accommodating and discharging apparatus having a drum for winding and rewinding two rows of tapes sandwiched on both sides together with a banknote and a reel for winding and rewinding the tape, And a pair of paper currency guides for guiding paper currency side ends to the outside of the outer end surface of the tape. As a result, it is anticipated that an effect of preventing breakage and jamming caused by discharge of the banknotes in a folded state is expected.

Prior art 2 stores and pays a paper sheet by winding and unwinding the tape between a first take-up drum with a tape wound from one end and a paper sheet positioned on the other end with a second take-up drum from which the tape is wound. A separation mechanism is provided on the pay-off side of the tape from the second take-up drum and separates the paper sheet from the peripheral region wrapped around the second take-up drum during payment. Thus, an effect of stably performing smooth separation of the paper sheet is expected.

However, the lower guide and the paper currency guide as in the prior art document 1 are insufficient to cope with the paper currency types of various sizes, and the separation mechanism as in the prior art document 2 increases the complexity of construction and the possibility of operation error. In addition, according to the prior art, it is difficult to secure operational reliability of depositing and withdrawing various types of coins in an aligned state.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes a banknote storing mechanism of a depositing and dispensing machine having a reflux path (15) of banknotes (B) on a main body (10). Reflux ATMs are widely used in banknotes for high-speed processing, but they are difficult to apply to service automation services and POS terminal services because of their complicated structure and large external dimensions. Since the present invention is applied to the vertical type, the bill inserted in the longitudinal direction into the charging port 11 is transferred to the recognition path 13, the waiting path 14, and the return path 15 on the main body 10. Such a path is constituted by a plurality of belt conveyors closely supporting both sides of the banknote in the upper and lower directions.

In FIG. 1A, reference numeral 21 denotes a deposit cassette for storing a reusable currency, and reference numeral 23 denotes a supplemental cassette for storing a reusable reusable currency.

According to the present invention, the reflux cassette 30 has the main drum 31 and the sub drums 41 and 42 communicating with the reflux path 15, and the film F is interposed between the main drum 31 and the main drum 31 Banknotes B are stacked. The reflux cassette 30 is installed on the bottom surface of the main body 10 in a modular manner so as to be removable and extendable. Referring to FIG. 1, the reflux cassette 30 includes a main drum 31 and sub-drums 41 and 42 in respective left and right spaces. The banknotes transported through the return path 15 flow into the left or right space of the reflux cassette 30 by the operation of the diverter 25. The introduced bill B is wound on the outer peripheral surface of the main drum 31 and stacked while being supported by the film F connected between the main drum 31 and the sub drums 41 and 42.

1B, the present invention provides a structure for easily expanding in the longitudinal direction by adopting a structure having a medium conveying path of bank notes on the main body of the reflux cassette 30 for the convenience of expansion of the reflux cassette 30 of the deposit- . In the drawing, one upper side and four lower side are illustrated, but they can be combined into a modular structure and expanded to various lengths.

At this time, the film (F) uses a resin material having abrasion resistance, heat resistance and chemical resistance together with good tensile strength. It is preferable that the film F is provided in a two-part structure between the main drum 31 and the sub drums 41 and 42. [ In this case, the film F independently supports both sides in a state in which the center of the banknote B is exposed.

The reflux cassette 30 supports the upper surface of the banknote B with the film F connected between the main drum 31 and the upper sub drum 41 and the upper surface of the main drum 31, And the bottom surface of the banknote B is supported by a film F connected between the lower sub drum 42 and the lower sub drum 42. [ 3, the banknote B is inserted between the upper film F supplied from the upper sub drum 41 and the lower film F supplied from the lower sub drum 42, and the film B supporting the upper and lower films F are sequentially wound on the main drum 31 together. Since the banknote B is stacked on the main drum 31 in a state that the banknote B is supported vertically by the film F, it is possible to reduce the stiffness and friction between the upper and lower bills, thereby improving the reliability of sheet separation at the time of settlement, .

At the beginning of use of the depositing and dispensing machine, all the films F are wound on the sub drums 41 and 42 and only the leading end thereof is connected to the main drum 31. [ The deposit of the banknotes is started by the reflux cassette 30 and the film F of the sub drums 41 and 42 is wound around the main drum 31 together with the bank notes. It is possible to accommodate approximately 60 to 70 banknotes B according to the standard of the main drum 31. [ Of course, the length of the film F determines the capacity of the banknote B to be stacked on the reflux cassette 30. The main drum 31 rotates in the reverse direction to send the film F to the sub drums 41 and 42 to discharge the deposited bank notes afterwards.

The main drum 31 and the sub drums 41 and 42 have one-way bearings 35 and 45 on the main shaft 33 and the sub shaft 43, respectively, according to the detailed configuration of the present invention . The main shaft 33 of the main drum 31 and the sub shaft 43 of the sub drums 41 and 42 are connected to the drive gear 64 via the gear train 63. The one way bearing 45 of the sub shaft 43 is idle while the bank gear is wound around the main drum 31 by the normal rotation of the drive gear 64 so that the power of the sub gear 47 is transmitted to the sub drum 43, (41) and (42). The one way bearing 35 of the main shaft 33 is idled and the power of the main gear 37 is transmitted to the main drum 31 when the bill is discharged on the main drum 31 by the reverse rotation of the drive gear 64 It does not. That is, the main drum 31 at the time of depositing pulls the film F of the sub drums 41 and 42, and the sub drums 41 and 42 pull the film F of the main drum 31 at the time of settlement.

The film F of the sub drums 41 and 42 is installed to be guided to the main drum 31 through a plurality of support rollers 39. [ The upper sub drum 41 and the lower sub drum 42 are connected to rotate through the gear train 63 at the same speed and direction.

According to the present invention, the compensating means 50 is provided on the sub drums 41 and 42 so as to exert a tension for preventing the film F from loosening. The diameters of the main drum 31 and the sub drums 41 and 42 are changed according to the winding and discharging of the banknotes. The controller 61, which will be described later, detects the change in the diameter and controls the feed rate of the film F. However, if the film F is loosened due to a momentary velocity discrepancy between the main drum 31 and the sub drums 41 and 42, the posture of the bill B may be distorted to easily cause an operation error. Since the relaxation of the film F is due to the temporary reduction of the tension due to the speed mismatch, the compensating means 50 is constituted so that the tension of the film F is always kept above the set value.

According to the detailed configuration of the present invention, the compensating means 50 includes a plate 51 provided on the sub-shaft 43 so as to be axially movable via a compression spring 52, A cover plate 53 for rotatably supporting the sub drums 41 and 42 via a torsion spring 56 and a friction plate 55 interposed between the plate 51 and the cover plate 53 . The upper sub-drum 41 and the lower sub-drum 42 are installed on the sub-shaft 43 so as to be rotatable within a certain angle range. A plate 51, a friction plate 55 and a cover plate 53 are interposed between the sub-drums 41 and 42 and the sub-

A pair of the plate 51 is installed via a pin 58 in the middle of the sub-shaft 43. The axial movement of the plate 51 is enabled by the slot of the plate 51 receiving the pin 58. A compression spring (52) is interposed in the middle of the facing plate (51) to exert an elastic force in both end directions. And the cover plate 53 is installed concentrically inside the sub drums 41 and 42. The cover plate 53 integrally has a disc at the outer end of the tube body, and is formed into a two-part structure for left and right for easy assembly. A torsion spring 56 is provided between the sub drums 41 and 42 and the cover plate 53. [ One end of the torsion spring 56 is connected to the sub drums 41 and 42 and the other end is connected to the cover plate 53 to buffer the relative speed difference. Between the plate 51 and the cover plate 53, there is provided a friction plate 55 which generates an appropriate frictional force. Wool felt, cork, or the like is preferred to rubber or resin having a high friction coefficient as a material of the friction plate 55 so as to perform a damping function by double slip.

The power of the sub shaft 43 is transmitted to the respective sub drums 41 and 42 through the plate 51, the friction plate 55, the cover plate 53, and the torsion spring 56. Even if the speed at which the film F is pulled and pulled out between the main drum 31 and the sub drums 41 and 42 is instantaneously inconsistent, the relative rotation between the sub drums 41 and 42 and the sub shaft 43, The tension of the film F can be appropriately maintained by the elastic force of the elastic members 56 and 56. That is, when the tension of the film F is reduced, relaxation is prevented by the elastic force accumulated in the torsion spring 56. When the tension is excessive, the elasticity of the torsion spring 56 and the slip of the friction plate 55 buffer the shock.

Of course, the compensating means 50 having the same structure as that described above can be applied to the main drum 31 although not shown in the drawings.

According to the present invention, the control means (60) changes the rotating state of the main drum (31) to keep the winding speed of the banknote (B) at a predetermined range. It is necessary to vary the feed speed of the film F corresponding to the diameter change of the main drum 31 and the sub drums 41 and 42 in the process of winding or discharging the banknote. For example, if the banknotes are rolled up, if the banknotes are stacked on the main drum 31 at a low rate, the speed is lowered. If the banknotes are stacked, the speed of the motor 62 described later is increased. The speed of the motor 62 varies in accordance with the diameter of the sub drums 41 and 42 even when the banknotes are discharged.

According to the detailed configuration of the present invention, the control means 60 includes a controller 61 equipped with a set program, a motor 62 for driving the main drum 31 and the sub drums 41 and 42, And a sensor for detecting a feeding speed of the sheet conveying device (F). The controller 61 uses a microcomputer circuit and mounts a program on the memory. The motor 62 is preferably a servomotor capable of rotating forward and backward. And a drive gear 64 on the drive shaft. The drive gear 64 is connected to the main gear 37 and the sub gear 47 via the gear train 63. As an example of the sensor, an optical sensor 65 of light emission-light receiving method can be used. A detection plate 66 is provided on one of the support rollers 39 and an optical sensor 65 is provided adjacent to the detection plate 66. [ Instead of the optical sensor 65, it may be replaced by another sensor for measuring the rotation state.

According to this method, the controller 61 can calculate the number of banknotes stacked on the main drum 31 by the signal of the optical sensor 65, and the stacking outer diameter of the main drum 31 corresponding thereto can be calculated on a separate table . The controller 61 changes the normal and reverse rotational speeds of the motor 62 using the updated calculation results. The tension of the film F is maintained at a constant level by the compensating means 50 even if an instantaneous speed difference occurs between the main drum 31 and the sub drums 41 and 42 as described above.

Meanwhile, in the reflux cassette 30, the existing products include only the reflux drum and thus constitute a separate path for expanding the reflux cassette 30, so that the reflux cassette 30 is structured to be freely expandable as shown in FIG. 1B .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
