Banknote pool detection structure of reject box {STRUCTURE FOR DETECTING OF BILLS TO BE FULLY STACKED IN A REJECT BOX}

The present invention relates to a sensing structure for detecting whether the banknotes stacked in the reject box is full, and in particular, a sensing sensor for detecting whether banknotes are full is installed on the upper side and the lower side of the banknote conveying path so as to increase the banknote loading amount. To a bill pull sensing structure (that is, a bill full sensing structure).

In general, an automated teller machine (ATM) includes an input unit for inputting information, a financial service menu, and a screen unit on which a transaction status is displayed. Is provided, the customer is to carry out cash withdrawal through the banknote withdrawal device. Here, "paper" (hereinafter referred to as banknotes) is meant to include all means that can be printed and distributed on paper with property values such as cash, checks and gift certificates.

Referring to FIG. 1, which is a schematic side view illustrating a general banknote deposit and withdrawal device, a financial control device in which banknotes are withdrawn and withdrawn, a control unit (not shown in the drawing) that controls the entire device, including the receipt and withdrawal of banknotes, and a customer inputs a banknote for withdrawal and withdrawal. Or the receipt and withdrawal unit 1 for receiving or receiving, the conveying path 2 through which the withdrawal and withdrawal is transferred through the withdrawal and withdrawal unit 1, a discrimination unit installed on the conveying path 2 to discriminate whether there is an abnormality of the banknote. (3), a temporary storage unit (4) for temporarily depositing the banknotes deposited after passing through the discriminating unit (3), a plurality of recycling to perform the reflux function by loading the banknotes deposited from the customer and withdraw the stacked banknotes A box 5 and a reject box 6 for receiving banknotes discriminated by abnormal banknotes from the discriminating unit 3 are provided.

In the reject box 6 of such an automatic teller machine, for example, a banknote which is determined as a counterfeit money in the discriminating unit 3 is stored, or a banknote which is sent out from the recycling box 5 by a customer requesting a withdrawal is withdrawn. Unreceived bills loaded in (1) but not received by the customer for a certain period of time may be stored.

A banknote pool sensing structure of a conventional reject box will be described with reference to FIG. 2. In Fig. 2, a feed roller 40a, a guide roller 30a for contacting the feed roller 40a and conveying the banknote P therebetween, and a part of the outer circumference of the guide roller 30a are coaxial with the guide roller 30a. The banknote P on the conveyance path 20 is laminated | stacked on the banknote stacking part 70 in the reject box 6 by the roller 50 etc. in which the several sheet | seat sheet 60 is formed in the inside. The controller 50 enters the conveyance path 20 at the time of stacking banknotes, and then faces the upper surface of the stacked banknotes P through a plurality of stack sheets 60 rotated by the rotation of the controller 50. Pressurizing, thereby serving to guide the banknote (P) to be aligned with the banknote stacking portion (70).

In the banknote sensing structure of the conventional reject box of FIG. 2, the sensing sensors 10a and 11a for detecting whether the banknote stacks are stacked in the reject box are arranged inside the banknote stacking part 70 of the reject box 6. It is installed on the ceiling and side walls respectively. The detection sensor is generally composed of an optical sensor, and includes a light emitting sensor 10a for oscillating an optical signal L and a light receiving sensor 11a for receiving an optical signal oscillated by the light emitting sensor. For example, in FIG. 2, the light emitting sensor 10a is disposed on the ceiling, and the light receiving sensor 11a is disposed on the upper side of the side wall. Banknotes stacked on top of the stacking portion are configured to block light emitted from the light emitting sensor 10a to the light receiving sensor 11a.

3 is a view showing the output waveform of the sensor of FIG. 2, when the stacking amount of the banknote stacking unit 70 does not reach the predetermined amount (normal signal), light of a predetermined period is emitted from the light emitting sensor 10a. When the signal L is oscillated, since the optical signal is periodically interrupted by the banknotes that are transferred to the banknote stacking unit 70 at a predetermined speed and stacked, the reception of the light receiving sensor 11a is repeated periodically. The low level (light) and high level (dark, dark) signals are output from the light receiving sensor 11a as shown in the normal signal graph of FIG. 3.

However, as shown in the output waveform of the full load signal of FIG. 3, the optical signal L periodically oscillated by the light emitting sensor 10a is blocked due to the banknotes stacked on the light receiving sensor 11a in the banknote stacking unit 70. Since the light receiving sensor 11a cannot continuously receive the optical signal L, a dark signal of the same level is continuously output and accordingly determined by a controller (not shown) that controls the transfer of bills. The transfer of bills to the reject box 6 is stopped.

 However, even when the full load signal is output as described above, in the conventional banknote sensing structure of FIG. 2, even though there is a space for stacking additional banknotes on the banknote stacking unit 70, the sensing sensor indicates the full load signal and rejects the box ( A part of the stacking space of the banknote stacking part 70 of 6) cannot be filled at all times, and thus has a problem of lowering the banknote stacking efficiency of the reject box 6.

That is, as shown in FIG. 2, the light emitting sensor 10a and the light receiving sensor 11a are respectively installed on the ceiling and sidewalls of the banknote stacking unit 70, so that the trajectory of the optical signal passes through the inside of the stacking space. The problem is that the light receiving sensor 11a outputs a full load signal even when banknotes can be stacked in the stacking space corresponding to the stacking space.

The problem of lowering the stacking efficiency of the banknote stacking unit as described above is that the sensing sensors 10a and 11a are installed in the banknote stacking unit 70, so whether the banknotes are loaded only through the banknotes transferred to the reject box 6 and stacked. It is related to the sense.

The present invention has been made to solve the above-mentioned problems, the bill detection structure of the reject box according to the present invention, each of the bill pull detection sensors on the upper side and the lower side of the conveying path outside the stacking portion of the reject box It aims at the objective of this invention to oppose and to improve the banknote stacking efficiency of a banknote stacking part.

In addition, an object of the present invention is to increase the banknote clamping force of the roller by forming irregularities on the outer circumferential surface of the guide roller and / or feed roller for guiding and transporting the bill to the banknote stacking portion.

The bill detection structure of the reject box according to the present invention includes: a feed roller and a guide roller installed on a conveyance path for transferring bills to the bill stacking portion of the reject box for transferring bills to the bill stacking portion; A first sensing sensor positioned between the entry portion of the banknote stacking portion and the rollers and installed on an upper portion of the conveying path; Located between the entry portion of the bill stacking portion and the rollers, it is characterized in that it comprises a second sensing sensor which is installed in the lower portion of the conveying path and facing the first sensing sensor.

According to the banknote sensing structure of the reject box according to the present invention, since the sensor does not display the full load signal until the banknote stacking space of the reject box is actually loaded, the banknote stacking efficiency of the banknote stacking part can be maximized and rejected. The efficiency of the box can be increased.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the banknote sticking prevention structure in the reject box according to the present invention.

4 shows a bill pull sensing structure of the reject box 6 according to an embodiment of the present invention. In the banknote pull sensing structure of the reject box according to an embodiment of the present invention, the banknote stacking portion 70 of the reject box 6 by the feed roller 40a and the guide roller 30a of the conveying path 20. The first detection sensor 10b and the second detection sensor 11b are positioned above and below the banknote P transferred to). That is, the detection sensors (10b, 11b) are located between the entry portion of the bill stacking portion 70 and the rollers (30a, 40a), based on the conveying path where the rollers (30a, 40a) are located It is installed on the upper side and the lower side, respectively. The sensor is generally an optical sensor using an optical signal, one sensor is a light emitting sensor for oscillating the optical signal, the other sensor is a light receiving sensor for receiving the optical signal. In FIG. 4, the upper sensor is the light emitting sensor 10b, and the lower sensor is the light receiving sensor 11b.

A case in which a normal signal is output in the bill pull detection structure of the reject box according to an embodiment of the present invention will be described with reference to FIG. 5. The light emitting sensor 10b is configured to emit an optical signal L of a predetermined period. And when the said optical signal L is interrupted by the banknote P conveyed at the predetermined speed along the conveyance path on the conveyance path 20, a high level (dark, dark) signal is output, and a banknote ( When not blocked by P), the light receiving sensor 11b is configured to output a low level (light) signal. Therefore, when the optical signal of a predetermined period is emitted toward the banknote conveyed at a constant speed on the conveying path, the signal output by the light receiving signal is a form in which high-level and low-level signals are repeated regularly as in the normal signal of FIG. to be.

On the other hand, when the banknotes are loaded in the banknote stacking unit 70, jams of the banknotes are generated on the conveying path, thereby gradually lowering the conveying speed of the banknotes on the conveying path. Therefore, when the light receiving sensor 11b, which outputs a regular light signal and a dark signal, is filled up to the ceiling of the banknote stacking unit 70, the banknote stacking unit ( The jam is generated by the interference between the banknote to be entered into 70) and the banknotes already stacked, and the jam is gradually worsened by the banknotes subsequently entering the bank stack. As a result, the frequency of the light signal when the optical signal oscillated by the light emitting sensor 10b is received by the light receiving sensor is gradually weakened, and the dark when the optical signal L is blocked by the banknote P ( dark) As the signal frequency gradually increases, the light receiving signal outputs a waveform such as the full load signal of FIG. 5. When such a waveform is output, it is determined by a controller (not shown) that controls bill transfer and stops bill transfer to the reject box 6.

One of the important differences between the sensor of the conventional banknote sensing structure shown in FIG. 2 and the sensor of the banknote sensing structure according to an embodiment of the present invention shown in FIG. 4 is that the sensing sensors of FIG. (70) While the banknotes stacked inside are placed opposite to each other and positioned therebetween to generate a light signal and a dark signal through the stacked banknotes, the sensing sensor of FIG. The banknote before stacking on 70 is used to generate a light signal and a dark signal.

In the banknote pull sensing structure of the reject box according to another embodiment of the present invention, the outer circumferential surface of the pair of feed rollers 40b and / or guide rollers 30b for transferring the banknotes on the conveying path 20 to the banknote stacking unit. It is possible to increase the banknote clamping force of the roller by forming irregularities in the roller.

Conventional rollers as shown in Figure 2 is generally formed of a rubber material, the clamping force of the rubber roller is reduced due to the material properties of the rubber material (for example, the coefficient of friction), the operating environment, damage to the rubber roller surface, etc. This can cause problems in separating and conveying banknotes.

Therefore, in another embodiment of the present invention, it is possible to increase the clamping force of the roller by forming irregularities on the roller surface in order to enhance the clamping force of the rubber roller, thereby increasing the contact surface area where the roller contacts the banknote. 6 and 7 are enlarged views of the dotted portion A of FIG. 2 and show that the unevenness is formed on the outer circumferential surface of the roller.

As shown in FIG. 6, the unevenness of the roller is preferably used when the unevenness of the symmetrical cross section is formed so as to rotate in both clockwise and counterclockwise directions. In addition, the unevenness | corrugation of the roller shown in FIG. 7 is preferably used for the roller which the uneven | corrugated cross section is formed in the asymmetrical cross section, and rotates to either one (clockwise direction in FIG. 7).

6 and 7, although irregularities are formed in the guide rollers 30b and 30c, the irregularities may also be formed in the feed rollers 40b and 40c. In addition, it may be preferable that irregularities are formed in both the guide roller and the feed roller.

On the other hand, as described above with reference to FIG. 4, when the bills are stacked close to the ceiling of the banknote stacking unit 70 beyond the transport path level, banknote stacking in the banknotes and transport path near the banknote stacking unit ceiling already stacked Interference occurs with the bill to be transferred to the unit 70 and the jam begins to deteriorate. Then, when the light receiving signal outputs a full load signal as shown in FIG. 5, a control unit (not shown) for controlling the bill transfer is determined to stop the bill transfer to the reject box 6.

However, in another embodiment of the present invention in which the roller clamping force of the roller is increased by employing the roller of FIG. 6 or 7, the banknote conveyance to the reject box 6 is not stopped even after the full load signal is output, and the roller outer peripheral surface By using the banknote clamping force strengthened through the irregularities of the bank can be forcibly transferred to the reject box (6). That is, through the irregularities formed on the outer circumferential surfaces of the feed rollers 40b and 40c and / or the guide rollers 30b and 30c, the paper money clamping force of the roller is sufficiently increased so as to overcome the interference between the paper money, and the increase is made. The banknotes on the conveying path are forced by the banknote clamping force, which is interposed between the pre-loaded banknotes of the banknote stacking portion 70, thereby enabling additional banknote stacking. Therefore, when the unevenness | corrugation of the outer peripheral surface of the roller which concerns on this invention is employ | adopted, the advantageous effect which was not expected in the prior art which further improves the banknote stacking efficiency of the reject box 6 can be acquired.

The bill pull sensing structure as described above may be used in a recycling box other than a reject box.

The present invention has been described using the preferred embodiments, but these embodiments are merely exemplary, and various modifications and changes may be made by those skilled in the art without departing from the spirit of the present invention. It will be appreciated that it can be added. In particular, the features of the present invention are not limited to those applied to the reject box, but may be applied to a recycle box or the like in which bills are stacked.
