FIG. 1 is a perspective view of a bill counter according to an embodiment of the present invention. FIG. 2 is an internal schematic view of a bill counter according to an embodiment of the present invention. It is a shave.

FIG. 4 is a right side view of a bill counter according to an embodiment of the present invention, and FIG. 5 is a schematic view of a sensor module of a bill counter according to an embodiment of the present invention.

1 to 4, a bill counter 10 according to an embodiment of the present invention includes a pickup roller 120, a feeding roller 140, feeding rollers 210 and 220, a motor 400, a flywheel 500, a sensor module 300, and loading members 630, 640, but does not exclude additional configurations.

Hereinafter, a bill counter 10 according to an embodiment of the present invention will be described with reference to a two-pocket bill counter including two loading members 630 and 640, but it is not limited thereto and can be applied to various types of bill counter have.

The pick-up roller 120 transfers a plurality of banknotes stacked on the stacking member 110 on which the user puts the banknote to be counted into the banknote counter 10. [

At this time, the pickup roller 120 may include a plurality of friction members 126 for transferring banknotes stacked on the lamination member 110 by frictional force. More specifically, when the pickup roller 120 has one friction member 126, the driving torque is increased and the capacity of the motor is increased as compared with the case where the plurality of pickup rollers 120 are provided. Therefore, since a large number of banknotes can be conveyed even through a small number of rotations through the plurality of friction members 126, a low-power motor 400 can be used.

When the pickup roller 120 has one friction member 126, the outer diameter of the portion including one friction member 126 is smaller than the outer diameter of the portion of the pickup roller 120 where the friction member 126 is not positioned The difference in specific gravity occurs. At this time, when the pickup roller 120 rotates at a high speed of 1000 times or more per minute, the eccentricity of the center of gravity due to the difference in specific gravity in the pickup roller 120 is generated, and the bill counter 10 itself trembles seriously. Therefore, by including the plurality of friction members 126 on the pickup roller 120, eccentricity of the center of gravity generated in the pickup roller 120 can be reduced, and vibration of the paper currency counter 10 can be reduced.

The number of the pickup roller 120 is not limited as long as the eccentricity of the center of gravity generated in the pickup roller 120 can be prevented.

Further, the friction member 126 pushes the banknotes stacked on the lamination member 110 by the frictional force to the separating roller 130 and the charging roller 140 which will be described later. However, if the stacked paper money can be pushed toward the separating roller 130 and the throwing roller 140, the frictional member 126 may be in contact with the friction material 126, The material and shape of the member 126 are not limited.

The charging roller 140 individually injects the paper money conveyed by the pick-up roller 120 into the paper currency counter 10. At this time, the input roller 140 and the separation roller 130 are adjusted so as to maintain a space of about one thickness of one banknote, and the separation roller 130 can be designed to rotate only in the counterclockwise direction. Therefore, when the input roller 140 rotates in the clockwise direction, when a plurality of banknotes are inserted, only one banknote can be passed by the frictional force of the separation roller 130. However, the detailed configuration of the input roller 140 and the separation roller 130 is not limited as long as one bill can pass through the space between the input roller 140 and the separation roller 130. [

The motor 400 provides a driving force to the input roller 140 connected to the input shaft 142 or the pickup shaft 122 and to the pickup roller 120 coupled to the pickup shaft 122 coupled to the input shaft 142 do.

3, the motor 400 includes a first input pulley 146 coupled to the input shaft 142 and a second input shaft connected to the input roller 140 provided on the input shaft 142, And the second input pulley 144 concentric with the first input pulley 146 is connected to the pickup pulley 124 coupled to the pickup shaft 122 by a second belt so as to be coupled to the pickup shaft 122 The driving force can be transmitted to the pickup roller 120 installed.

The motor 400 is connected to the third pickup pulley coupled to the pickup shaft 122 by a third belt to provide a driving force to the pickup roller 120 installed on the pickup shaft 122, The fourth pickup pulley having a concentric center may be connected to the input pulley coupled to the input shaft 142 by a fourth belt to transmit the driving force to the input roller 140 provided on the input shaft 142.

The motor 400 may be connected to the input shaft 142 or the pickup shaft 122 so as to provide a driving force to the input roller 140 or the pickup roller 120 and the input shaft 142 and the pickup shaft 122, The connection method between the motor 400, the input shaft 142, and the pickup shaft 122 includes all the connection methods applicable to the ordinary art in the technical field of the present invention, as long as the driving force can be transmitted to each other.

Therefore, the driving force can be provided to the input roller 140 and the pickup roller 120 by one motor 400.

The conveying rollers 210 and 220 count paper bills, recognize the liquid level, transfer the paper money fed into the paper currency counter 10 one by one to perform operations for detecting whether the paper is counterfeit or tampered, And then the processed bills are transported to the loading members 630 and 640.

The forged or modulated bill or the unidentifiable bills are conveyed to the first loading member 630 and the forged or unmodified normal passage is conveyed to the second loading member 640 to rotate the wheel 620 ). ≪ / RTI >

At this time, the bill counter 10 according to the embodiment of the present invention changes the conveying path of the bill conveyed by the conveying rollers 210 and 220 to convey the bill to the appropriate one of the stacking members 630 and 640 A selector 610 may be further included. Specifically, the selector 610 sends bills suspecting forgery or modulation to the first stacking member 630 located at the upper end according to the result of the sensor module, which will be described later, 2 stacking member 640 as shown in Fig. In this case, the bills to be sent to the second stacking member 640 located at the lower end can be counted by the counting module.

4, the conveying rollers 210 and 220 may be installed on the conveying shafts 212 and 222 connected to the input shaft 142 and rotating together with the input shaft 142. For example, the transfer pulleys 214 and 224 coupled to the transfer shafts 212 and 222 are connected to a third input pulley 148 coupled to the input shaft 142 so that the transfer rollers 210 and 220 can be rotated And can rotate as the roller 140. Accordingly, since the pickup roller 120, the feeding roller 140, and the feeding rollers 210 and 220 can be rotated through the driving force provided from the single motor 400, the cost can be greatly reduced and the bill counter ) Can be simplified.

The conveying rollers 210 and 220 are driven by a first conveying roller 210 for conveying the inside of the banknote counter 10 by the input rollers 140 and the separation rollers 130, And a second conveying roller 220 for discharging the paper currency conveyed by the first conveying roller 210 to the outside of the paper currency counter 10 (for example, a loading member). Therefore, it is possible to change the path of the paper money to be transported through the plurality of transport rollers 210 and 220, thereby improving the space efficiency in the paper money counter 10.

The flywheel 500 may be inertially rotated to discharge the remaining banknotes in the transfer spaces P1 and P2 to the outside when the driving force provided from the motor 400 is interrupted. Here, the flywheel 500 means a part having a considerably large mass among the components of the bill counter 10, and capable of continuing to rotate by the rotating inertia when the driving force of the motor 400 is supplied and shut off .

The flywheel 500 is installed on the conveying shafts 212 and 222 and rotates together with the conveying rollers 210 and 220 so that when the driving force provided from the motor 400 is cut off, The remaining banknotes in the transfer spaces P1 and P2 can be discharged to the outside.

Further, the third pulley 148 coupled to the input shaft 142 may be press-fitted with a one-way bearing rotatable only in one direction. This is because the third pulley 148 and the conveying pulleys 214 and 224 are continuously rotated by the rotational inertia obtained while the flywheel 500 rotates even if the driving shaft provided from the motor 400 is interrupted to stop the closing shaft 142. [ . Therefore, compared with the conventional method using a separate motor for removing the remaining banknotes in the transfer space when the driving force provided from the motor 400 is cut off, the structure of the banknote counter 10 is simplified and the cost is greatly reduced .

The sensor module 300 is installed in the conveyance spaces P1 and P2 to sense the level of the banknote being transported or whether the banknote is forged or not. Specifically, the sensor module 300 includes an optical sensor including an infrared ray, an ultraviolet (UV) sensor, and a magnetic sensor, so that the sensor module 300 can recognize whether the bill is forged or altered by recognizing the bill.

At this time, the sensor module 300 may be installed in the space P1 between the feeding roller 140 and the first feeding roller 210 in the feeding spaces P1 and P2. Therefore, even if the flywheel 500 has a low rotational inertia, when the driving force provided from the motor 400 is cut by minimizing the transfer space of the banknote by the sensor module 300 being located in a part of the transferring space P1, So that the remaining banknotes in the spaces P1 and P2 can be discharged to the outside of the banknote counter 10. [

To this end, the sensor module 300 includes a first light source 310 that emits light from one side of the paper currency to be transported, a second light source 320 that emits light from the other side of the paper currency to be transported, And a detection sensor 330 for detecting light irradiated from the bill 310 and light reflected from the bill and light emitted from the second light source 320 and transmitted through the bill. 5, the space in which the sensor module 300 is located is reduced through the first light source 310, the second light source 320, and the sensing sensor 330, which are located on substantially parallel lines, Can be improved. In this case, the light emitted from the first light source 310 and the second light source 320 includes infrared light, visible light, ultraviolet light, and the like, and various light beams may be combined. The first light source 310, the second light source 320, and the detection sensor 330 may detect the level of a banknote to be transported by a conventional technician in the technical field of the present invention, And may include all light sources and sensors that can be used.

Hereinafter, the operation of the bill counter 10 according to the embodiment of the present invention will be described.

Since one bill per rotation of the input roller 140 is fed into the bill counter 10 in the present embodiment of the present invention, the flywheel 500 ) Will be described.

6 is a view showing a conveyance space in which banknotes are conveyed by a bill counter according to an embodiment of the present invention.

Referring to FIGS. 2 and 6, when the banknotes are put into the counter unit by the input roller 140 and the separation roller 130 one by one, the banknotes are discriminated and counted through the positions A to F or A to G, . Even when the banknote is fed by the flywheel 500 by the length r in the case where the motor 400 is stopped and the supply of the driving force is interrupted while the banknote is put in the j position, , And the inserted paper currency is completely discharged when it is transported by a length of about 1.5r in which the charging roller 140 rotates 1.5 times.

Therefore, when the bill counter 10 provides a plurality of counting speeds, the residual bill in the conveying spaces P1 and P2 is discharged to the outside of the bill counter 10 even with the inertia obtained by the flywheel 500 at the minimum counting speed The flywheel 500 at the maximum counting speed of the bill counter 10 can be designed to rotate inertially about the feed rollers 210 and 220 by twice the circumferential length r of the feed rollers 140. [ In one embodiment of the present invention, the maximum counting speed of the bill counter 10 is 1000 sheets per minute, and the minimum counting speed means the speed of counting 800 sheets of paper money per minute, but is not limited thereto and can be variously changed.

The total length (for example, A to F, or A to G sections) of the conveyance spaces P1 and P2 to which the bank notes are fed may be less than twice the circumference r of the feeding roller 140. [ If the total length of the transferring spaces P1 and P2 is twice or more than r, the weight or the outer diameter of the flywheel 500 must be increased. This may increase the load of the motor 400, Thereby increasing the driving load. In this case, since the flywheel 500 needs to accelerate the rotation of the motor 400 in order to obtain sufficient inertia, the flywheel 500 is deviated from the purpose of the present invention. Minimizing the conveyance interval in this manner can be achieved through the configuration of the sensor module 300 and the conveyance rollers 210 and 220 described above.

Therefore, even when the drive force provided from the motor 400 is cut off through the degree of inertial rotation of the flywheel 500 and the length of the transfer spaces P1, P2, the remaining bills in the bill counter 10 can be discharged As well as the inertial rotation of the appropriate flywheel 500 to provide a driving force with adequate acceleration in the event that the motor 400 provides the driving force again in the stationary state.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
