BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a jam removing device for a cash dispenser, and more particularly, to an automatic jam removing device comprising jam recovery by self-diagnosis of the device itself and a jam removing method for recovering jam using the device.

BACKGROUND ART [0002] Generally, a main part of an automatic teller machine is composed of a driving unit for driving an entire mechanism by rotation of a motor, a pulley for receiving power of the driving unit to transmit power to the desired destination in an interlocking relationship, A paper feed and take-out unit including a cash box for guiding the setting of the paper currency and the sheet take-out, and a checking sensor disposed on the conveying path of the paper currency, And a controller for controlling the bill transfer.

1 shows a typical configuration of a conventional automatic teller machine, which comprises a motor 1 for generating a driving force, a timing belt 3 for transmitting the rotation of the motor 1 to the counterpart, and a timing belt 3 And a plurality of pulleys (2) and gears (4) that are distributed and arranged at the proper positions so as to receive the power to rotate and transmit the paper currency to the other side.

A conveyance belt 5 for conveying the paper money while keeping the conveyance path of the paper money constant while conveying the pulley 2 and the gear 4 in an interlocking relationship with each other; A sensor 6 for independently detecting the banknote conveying state, a cash box 7 for feeding the banknote to the conveying route side, and a cash box 7 for collecting banknotes A reject box 8 is provided.

The banknote conveying state performed in the automatic teller machine of FIG. 1 is divided into a first paper feeding unit 9, a second paper feeding unit 9a, a thickness detecting unit 13, a reject unit, a banknote delivering unit, do.

The paper money feeding section 10 for merging the first paper-feeding section 9 and the second paper-feeding section 9a into the same area, the first paper-feeding section 11 for guiding paper money passed through the paper money- And a second transfer unit 12.

However, the arrangement of the conveyance unit including each of the paper-feeding units may vary depending on the product size and the installation conditions, may have a single paper currency feeding and conveyance path, and may be extended to a further paper feeding and conveyance path.

First, when the motor 1 is rotated in one direction, the rotational force is transmitted to the pulley 2 through the timing belt 3. [

The rotational force transmitted to the pulley 2 is dispersed to other positions to provide a banknote conveying path and to rotate another pulley 2 and a gear 4 that move the banknote conveying belt 5, .

When the banknotes in the first paper-feeding unit 11 and the cash box 7 on the second paper-feeding unit 12 are taken out one by one from the paper money feeding unit 10, the motor 1 rotates to rotate the power transmission pulleys 2, The timing belt 3 rotates the bill 4 and the bill conveyance belt 5 that spans the conveyance units 11 and 12 in which the gears and the pulleys are clustered to rotate the take- Lt; / RTI >

In the bill transfer process, each sensor 6 and thickness detector 13 checks whether the bill is fed or not, and determines where to branch the bill.

If the banknote is borrowed with more than one banknote, the banknote is branched in the direction of the arrow "B" to convey the banknote to the reject box 8. If the banknote is a normal banknote, the banknote is branched in the direction of arrow "C" .

The banknote branching method according to the present invention includes the steps of feeding a single banknote stored in the cash box 7 through the first paper-feeding unit 9 and the second paper-feeding unit 9a, A first feeding step of feeding banknotes to be conveyed along the conveying belt 5 to a predetermined path, and a second conveying step of conveying the banknote conveyed along the conveying belt 5 to the banknote conveying path, A second feeding step of continuously feeding the banknotes through the thickness detecting step; and a branching step of branching out the banknotes transported in the step to the reject box or the customer delivery section.

However, in such a conventional cash dispenser, it has been found that it is difficult to remove the jam when the paper jam occurs in the paper currency branching step including the paper currency transfer.

For example, when the banknote conveying portion is divided into the first conveying portion 11, the second conveying portion 12, and the like, and has the overlapped banknote conveying path, it is necessary to manipulate the management personnel to remove the jam by the occurrence of the local jam And it takes too much time for recovery, which is a burden of managing the apparatus.

In addition, the entire mechanism is not compact in configuration, and there is a problem that the unnecessary consumable space is large and the product size is larger than the available apparatus.

For example, an increase in the cost of input materials and an increase in the number of work processes in the manufacturing process lead to a rise in cost.

In addition, in the entire mechanism, there is a problem that the bill transferring section becomes excessively long, so that the initial discharge time of the wafer is relatively long and the actual discharge speed is lowered.

Accordingly, an object of the present invention is to automatically remove jams caused by the paper money transfer path of the automatic teller machine to recover.

Another object of the present invention is to shorten the transfer interval of the entire bill by implementing the light and short cut of the automatic teller machine, thereby reducing the initial discharge time, thereby speeding up the discharge speed.

It is still another object of the present invention to provide a new jam removing method that improves the bill ejection speed, realizes a thin and compact product, and eliminates the occurrence of jams on the bill transfer path.

In order to achieve these objects, a feature of the present invention is to provide a banknote transferring roller, an open / close transfer detecting unit for detecting a bad banknote and a banknote jam when the banknote is transported, a defective banknote to a reject box, And an automatic jam branching unit for transferring the banknotes which are jammed and removed by reverse rotation of the rollers when the banknotes are jammed to the reject box, A step of detecting the feeding state of the paper currency, a step of changing the feeding path to the reject box when detecting a bad banknote, a step of reversing the banknote interlocking roller, And transferring the banknotes transferred by the reverse rotation of the banknote to the reject box.

The automatic teller machine of the present invention includes a banknote dispensing roller for checking whether a banknote is defective and a main part for sending the banknote to a branching part as shown in FIG. 3, a banknote conveying backstroke sensing part for detecting a bad banknote, A customer delivering section and a reject box branching section for selecting and changing the conveying path so as to send the faulty banknotes to the reject box 29 and to send the normal banknotes to the cash feed line, An automatic jam branching section 31a for transferring the banknotes to which the jam has been removed to the reject box 29 and an automatic jam branching section 31 The automatic jam removing device of the automatic teller machine includes divert means for guiding the conveying path of the selected banknote.

Basically includes a motor 20 for generating power, a pulley 21 and a gear 22 for receiving and transmitting power to the motor 20, a timing belt 23 connected to the pulley 22, (24) constitute a power transmission system.

The paper feed unit is divided into a first paper feed unit 26 and a second paper feed unit 27 by arranging the two cash boxes 25 and 25a in a symmetrical structure to form the area of the paper currency paper feed unit 28.

The reject box 29 is provided with separate collecting holes 30 and 30a on the upper and lower sides in order to collect the paper money sent through the paper currency paper feed unit 28.

The branching device secures its own movable area at the periphery of the collection port 30 (30a), hides the state of the banknote through movement in the area, selects the route of the banknote thereafter, The automatic cash dividing section 31 and the customer delivering section 32 or the customer delivering section 32 are disposed at different positions in the paper feeding section in which the cash boxes 25 and 25a are separated into two, The reject box 29 is provided with another branch 33 for determining the banknote conveying direction.

And detects the banknote jam state by the automatic jam branching section 31 (31a) and the sensors (S1 to S5) installed on the periphery of another branching section 33 and the banknote conveying path, And a paper currency transfer detecting unit and a duplicate conveyance detecting unit for switching the operation mode in which the rotation direction is adjusted to the paper currency release to the rejecting mode.

And a fourth means for guiding the conveyance / rejection of the banknotes without affecting the conveyance of the banknotes when the banknote discarding of the banknotes in the sensing unit is completed.

The diverting means includes a diverter (34) having an axial coupling structure and sharing an induction surface for guiding the paper currency in the direction while turning, a shaft (35) for rotatably supporting the diverter (34) And a spring 36 that urges the diverter 34 against the shaft 35 to provide a directional elastic force to the diverter 34 side fixed to the shaft 35.

On the other hand, the main components of the power transmission system constituting the automatic jam branching sections 31 (31a) are fabricated in the same manner as the fifth aspect.

(A) is a roller (38) having a pulley (21) and a detec- ting roller (37) installed on the shaft for detecting the overlapping of paper currency.

(B) is a conveying roller (39) having a detec- tive roller (37) attached thereto for detecting the overlapping conveyance of the banknote while engaging with the detec- tor roller (37) and conveying the banknote using the conveyor belt (24).

(C) is a roller (40) for conveying banknotes in engagement with the conveying rollers (39) and the conveying belts (24).

(D) is a conveying roller (41) having a conveying gear (22) for forming a banknote conveying path by the conveying belt (24).

(E) shows a rotary roller 42 that receives the rotation of the motor 20 and forms a banknote conveying path through the roller.

Hereinafter, the operation of the power transmission system based on the paper money feeding, the interlocking relationship between the respective parts and the effect thereof will be described as follows.

The transfer of bills starting with the first paper currency has a path to the paper feed, automatic jam branching, duplicate transport detection, customer delivery and final branch selection of the route to the reject box.

3, when a banknote is received in the cash boxes 25 and 25a and an external emission signal is inputted, the banknote paper feeding unit 28 is activated to take out the banknotes in the cashboxes 25 and 25a one by one, The banknote taking-out operation and the rotation of the motor 20 are simultaneously performed to prepare a path for carrying the banknotes taken out through the respective power transmission systems including the power transmitting pulley 21 and the timing belt 23 to the destination .

In the initial stage, most of the power transmission system is in the idling state, but the first step of detecting the abnormality of the first banknote by the sensors S3 and S5 that detect the bad / normal banknotes is performed first as the banknote feeding progresses If it is found to be defective, it is recovered to the reject box 29 by the branching unit which will be described later.

When the banknote which has passed through the detecting step is approaching the automatic jam branching part 31 (31 (a)), if the number of banknotes exceeds two or more in order to secure a proper conveying state on the conveying path, The automatic jam branching step of recovering and recovering the obstacle factor that is inconsistent with the continuous conveying condition of the bank notes is performed. In this process, the conveyance failure of the bank notes is corrected to decrease the jam occurrence probability and only the normal jeep is passed to the next step .

However, although the jam removal of bank notes at this stage solves a direct cause such as jamming of the paper currency, it is possible to detect the abnormal movement of the paper currency due to such a problem and to recover it to the reject box 29, In this process, the situation such as shutdown of the entire dispenser is excluded and it is recovered by itself and enables continuous operation.

That is, as shown in FIG. 4, the diverter 34 receives unidirectional elasticity, and is rotated by the moving force of the banknote to rotate the shaft 35 about the axis to determine the feeding direction of the banknote.

6 shows the dynamic movement of the diverter 34. FIG. 6 shows a state in which the paper currency is moved in the direction of the arrow in the direction of paper conveyance,

(B) is a state in which a banknote pushes the diverter (34) and passes through a predetermined path,

The position of the divertor 34 returned to its instantaneous elasticity while the direction thereof is reversed due to the reverse rotation of the transport roller 40, The paper money is transported to the reject box 29 as it is.

An example in which the path of the banknote is changed to the reject box 29 through the diverting process is that once the status of the banknote is detected by the detection sensors S1 to S5, So as to switch the direction of rotation of the conveying roller (40).

Conversely, the normal banknote moves along the specified subsequent path.

More specifically, the conveying path of the banknote passing through the automatic jam branching portion 31a on the second paper-feeding unit 27 side is carried by the conveyor belt 24 and the rollers 38 and 39 and continues to ascend toward the first paper-feeding unit 26 side , The first paper-feeding unit 26 side reaches the branching unit 33 side where the banknote passing through the automatic jam branching unit 31 reaches the final stage. The normal paper money transporting is performed by the banknote conveyance detecting sensors S1 to S5, The banknote is delivered to the customer through the conveyance path as shown in FIG. 7 (A) only when there is no abnormality in the detection result of the banknote detection on the side of the overlapping conveyance detecting section 43 made up of the sensor 37. In other cases, (S1) and the duplicate conveyance detecting unit (43), it is sent back to the reject box (29).

Meanwhile, according to the present invention, jamming of bank notes by the jam branching sections 31 (31a) located on each path is prevented in advance as described above, and a jam recovery function is provided even in a situation such as occurrence of jamming during transportation There is.

For example, in FIG. 3, when a jam occurs in the area of "J1", the paper jam state is detected in the sensors S1 and S2 adjacent to each other and the motor 20 is reversely rotated, And the sensor S4 detects the jam state when the jam occurs in the "J2" area, and the banknote jam is recovered by recovering the banknote jam by changing the rotation direction of the motor 20 .

Accordingly, the present invention provides a function of suppressing and preventing the possibility of occurrence of jamming by judging the abnormal traveling route of the paper money including the jam of the paper money, the meandering, And to recover from the occurrence of the event.

Meanwhile, the automatic cash dispenser according to the present invention is provided with a new jam removing method through arrangement of a power transmission system, a change of a conveying path of a bill, and the like.

The method comprises the steps of transferring banknotes to a customer delivery unit, detecting the state of delivery of the banknotes by the sensors dispersed at the respective positions in the transferring step, if the banknotes are detected as bad banknotes in the transferring step, A first diverting step of guiding the conveyance direction of the banknotes converted in the step to the reject box and a gem occurrence on the bill conveyance path are detected through a sensor to detect the occurrence of a gem on the bill conveyance path, And recovering the jam to recover the jam.

Accordingly, the present invention has an effect of automatically eliminating jam caused on the bill transfer path of the automatic teller machine and restoring the jam, and also filtering the conveying state of the bill to suppress the possibility of jamming, thereby relieving the burden of management personnel You can develop into a result.

In addition, the present invention realizes the light and short cut of the automatic cash dispenser, shortens the transporting interval of the entire paper money to shorten the initial discharge time to speed up the discharge speed, and provides a low-cost mechanism through the simplified device and improves the installation environment .

Further, the present invention has an effect of obtaining a new jam removing method for eliminating the occurrence of jam on the paper currency transfer path and reflecting the new jam removing method in a design for seeking a new change of the apparatus.
