Description

Small paper money counter using air cylinder {A paper money counter using air cylinder}

The present invention relates to a small bill counter using an air cylinder, and specifically, to start counting in a state where the conditions of the bill detection sensor, the count sensor, and the pressure sensor are satisfied to enable a stable counting of bills, and the pressure sensor By driving the rotor drive motor through the motor drive interface according to the measurement value of the bill, the counting of bills is made by the rotor or the pressure sensor is adjusted appropriately by the pressure sensor so that the stable counting is possible even if the pressure changes according to the terrain. In addition, the present invention relates to a small bill counter using an air cylinder that enables the implementation of a billing system that receives and transmits an aggregate value by a count while communicating with a plurality of computers through a communication modem.

The conventional banknote counter is a method of performing the counting by approaching the counter 550 in a state in which the support 380 of the banknote 900 supports the banknote as shown in Figure 1, the means for transferring the support is a timing The cam method and lead screw method were mainly used.

However, the timing cam method has a problem in that a lot of noise is generated in the connection portion and the structure is increased, so that a lot of parts are required, thereby increasing the installation space.

In the lead screw method, when the lead screw 210 is rotated using the motor 100 and the pulley, the nut member 232 on the lead screw is moved in a linear motion by the rotation of the lead screw. The entire support, which is connected to it, was also rotated about the axis of rotation to bring the banknote closer to the counter.

In addition, a spring 336 is always provided to exert a pulling force against the outside, so that when the bill 900 is attached to the counting spindle 551 and counted, the counting can be smoothly progressed by attaching a few bills toward the spindle. To help.

However, in the conventional counter of this type, since the bolt member on the lead screw causes friction with the lead screw during the rotational movement of the bank note support, the support transfer is not accurately controlled by the wear of the screw or the like when driven for a long time. In addition, the generation of particles due to friction may act as a cause of malfunction while remaining inside the device that requires precise control. In addition, noise generated by friction may adversely affect a worker's office environment.

As the banknotes are counted, the thickness of the uncounted banknotes becomes thinner. At this time, if the banknotes are not pressed on the spindle 551, an error may occur in the counting. It is necessary to rotate little by little. However, since this is a lead screw method, such precision and natural movement is difficult to expect, so instead it is performed by the pulling force of the spring 336. However, such a design, as shown in the spring 336 and other peripheral components are intricately intertwined structure, and thus suffers from the original problem that the increase in manufacturing cost and the probability of failure is high.

The present invention for solving the conventional problems as described above relates to a small bill counter using an air cylinder configured to use a solenoid and a piston using air pressure instead of a friction type lead screw to move the bill support of the bill counter.

In addition, the present invention is to start the counting in a state that satisfies the conditions of the bill sensor, the count sensor and the pressure sensor to enable a stable count of the bill, and the rotor drive motor through the motor drive interface by the measured value of the pressure sensor While driving, the count of bills is made by the rotor or the pressure of the vacuum pump is properly adjusted by the pressure sensor, so that stable counting is possible even if the pressure changes according to the terrain, and it communicates with multiple computers through a communication modem.

It comprises a rotor 11 and a suction spindle 12 for counting the bundle of bills 50 transferred in a straight line by the clamp transfer unit (10) (13).

In addition, the banknote detection sensor (B) of the light receiving element (2) and the light emitting element (3) for detecting whether the bill bundle 50 is inserted into the bill clamp (A) on both sides of the sensor support (1),

The degree of rotation is detected when the clamp sensor 8, 9, the rotor 11, and the suction spindle 12, which detect whether the banknote clamp part A is in the correct position, count the bundle of banknotes 50 while rotating. It further includes a bill counter sensor (not shown in the figure) for counting the number of sheets of bills 50.

The banknote clamp portion A includes a first support 4 and a second support 5 supporting the bundle of bills 50 and are fitted with any one or all of the supports 4, 5. The clamp conveyance part of the clamp solenoid 10 and the solenoid arm 13 which carries in the direction of a support piece so that the banknote bundle 50 may be crimped | bonded and hold | maintained is lower.

The bill detection sensor (B) consists of a pair of light-receiving elements (2) -light-emitting elements (3), and the bundle of bills 50 is inserted therebetween to cover light between the two elements. Since it is not input to the light receiving element 2, it detects this to recognize the existence of the banknote 50.

The clamp sensor unit is also composed of a first clamp sensor 8 and a second clamp sensor 9 to grasp the banknote insertion position and the counting position into the banknote clamp A, respectively.

Figure 3 illustrates a configuration including a microprocessor for controlling the operation of the present invention,

The measurement value of the banknote detecting sensor B, the clamp sensors 8 and 9, the count sensor 21 and the pressure sensor 22 of the light receiving element 2 and the light emitting element 3 is transmitted through the sensor interface 23. The receiving microprocessor 24 receives the set value of the key input unit 25 through the interface 26 and counts the coefficient in a state where the conditions of the bill detection sensor B, the count sensor 21, and the pressure sensor 22 are satisfied. Let's get started

The microprocessor 24 drives the clamp solenoid 10 through the solenoid interface 27 to move the bundle of bills 50 clamped to the clamp portion A to the counting position of the rotor 11.

The microprocessor 24 counts the banknote bundles 50 by the rotor 11 while driving the rotor driving motor 29 through the motor driving interface 28 according to the measurement of the pressure sensor 22. To adjust the pressure of the vacuum pump 30 by a pressure sensor or

The microprocessor 24 causes the coefficient display unit 32, the number setting display unit 33, and the customer display unit 34 to display the result of the coefficient through the display unit interface 31,

The microprocessor 24 may implement a billing system that receives and transmits an aggregate value based on coefficients while communicating with a plurality of computers 36 through a communication modem 35.

The internal parts including the microprocessor 24 may be operated by a general power supply circuit for supplying AC power supplied from the switching mode power supply (SMPS) to operating power.

4 to 7 is a view showing in more detail the state that is counted by moving the support and the banknote of the present invention bank counter, it will be described in detail the process of counting the banknote according to Figs.

Referring to FIG. 4, first, a banknote 50 is inserted between both supports 4, 5 by a user, and then a bill counter sensor B composed of light receiving and light emitting elements 2, 3 pairs is a bill counter. The counting process is started by inputting a counting start signal into the microprocessor 24 within.

The banknote detecting sensor B formed of a pair of the light receiving elements 2 and the light emitting elements 3 is disposed to face each other on the sensor support 1 to input light generated by the light emitting elements 3 from the light receiving elements 2. To receive it.

In this case, since the light-receiving element 2 may receive light from the light emitting element 3 in a state in which the wad of bills 50 is absent, the wad of bills 50 is not drawn by outputting a specific signal such as a low signal. However, if the bundle of bills 50 is drawn and covered between the two elements as shown, the light receiving element 2 does not receive the light from the light emitting element 3, and thus a high signal is different. Outputs to the microprocessor 24 in the banknote counter via the sensor interface 23 and the microprocessor receives it so as to recognize that the bundle of bills 50 is drawn in and counting should begin.

The initial pressure value measured during 2 to 3 rotations by the initial operation of the rotor 11 and the suction spindle 12 is inputted with the value "0" according to the initialization of the count sensor 21. The average value of the pressure is set by receiving the calculation through the calculation.

In addition, the normal counting operation starts only when the conditions through the banknote detecting sensor 2 (3), the count sensor 21, and the pressure sensor 22 are satisfied.

When the microprocessor 24 determines the start of the counting, the clamp portion A including the first support 4 is moved by moving the clamp solenoid 10 which is operated pneumatically through the solenoid interface 27 as shown in FIG. 5. While moving the whole to the right, at the same time using the solenoid arm 13 to move the second support (5) to the left also by pneumatic bills while the two support (4) (5) squeezed the bundle of bills 50 in both directions Clamp the bundle 50.

During the process of clamping the bill bundle 50, the entire clamp portion A is continuously moved to the bill counting position to the right by the clamp solenoid 10 as shown in FIG. 6, and eventually the bill bundle 50 is rotated. It moves to the point of close contact with the suction spindle 12 of the rotor 11.

When the bill of paper 50 moves to the point where it is in close contact with the suction spindle 12 of the rotor 11, the actual counting starts. At this time, the second clamp sensor 9 is additionally provided so that the clamp unit A is properly billed. It detects whether it is in the counting position and, if it is not in position, notifies the microprocessor 24 to control the clamp solenoid 10 so that the position of the clamp unit A can be adjusted.

Of course, this process is not necessary, and the travel distance may be set in advance so that the bill bundle 50 is approximately positioned on the suction spindle, and both methods may be used to increase the accuracy of the travel distance control.

When the clamp portion A normally moves to the banknote counting position, the microprocessor 24 causes the banknote bundle 50 to be stuck by the suction force of the suction spindle 12.

The suction force of the suction spindle 12 is generated by the air pump connected to the spindle to exhaust the air inside the spindle to create a pressure lower than atmospheric pressure inside the spindle. The bill bundle 50 close to the holes is naturally sucked and attached.

While attaching and counting the banknote bundle 50 by the suction spindle 12, the microprocessor 24 measures the strength of the pressure to suck the banknote bundle 50 through the pressure sensor 22 according to the terrain. Different air pressure causes a difference in pressure so that the suction force applied to the bundle of bills 50 does not change and can always be a constant value.

When counting the bundle of bills 50 stuck to the suction spindle 12, the rotor 11 rotates while the drive motor 29 is driven by the microprocessor 24 via the motor drive interface 28. Count each chapter of the bundle (50).

At the same time, the individual suction spindles 12 on the rotor 11 rotate to turn over the counted bills.

Although the said coefficient may count the number of the banknote bundles 50 which were put, in some cases, the user may count the desired number of bank notes.

Therefore, when the user inputs a desired number through the key input unit 25, the microprocessor 24 that recognizes the number is displayed to check and display the number set in the number setting display unit 34.

The rotor rotation method and bill movement related to the coefficients are already described by Patent No. 10-192633, and thus detailed description thereof will be omitted.

The count can be counted using one or both of the pressure sensor 22 attached to the rotating rotor 11 and the reflective sensor disposed on the side of the rotor 11 as a bill counter.

When counting using the pressure sensor, the bill can be counted using a pressure sensor connected to the suction spindle 12. Whenever the bill sticks to the spindle one by one, the hole in the spindle is blocked and the pressure in the spindle is blocked. When the bill is pulled down and turned over from the spindle, the pressure rises again, so the pressure pulse generated is measured and the bill is counted by the number of pulses.

In addition, in the case of using the counting method of the reflective sensor separately, a predetermined number of grooves having good reflectance along the circumference of the rotor 11 are formed on the side of the rotor 11, and the light is reflected on the grooves. It is a method of detecting light reflected from a groove by placing a groove of a reflective sensor that receives light and measures reflection.

That is, when the rotor 11 rotates, the grooves on the side also rotate, and the sensor is excessive. At this time, the intensity of the reflected light appears as a pulse wave each time one groove passes, so the pulse wave due to the reflected light is counted and the rotor It is a method of finding out the rotation degree of (11), ie, the number of bills counted.

The counting method of the present invention may use any one of the above-described pressure sensor and reflective sensor, but may be configured to improve the accuracy of the coefficient by recognizing the coefficient only when the result data coincide with each other while using both methods. .

While the above counting is in progress, the microprocessor 24 displays the number of bills counted on the count display 33 and the customer display 34 through the display interface 32 so that they can be visually confirmed.

When the count is completed and all the bills 50 are counted, all the bills 50 between the first support 4 and the second support 5 are placed between the light receiving element 2 and the light emitting element 3. Since it is arranged as shown in FIG. 7, the light receiving element 2-light emitting element 3 senses that there is no bill and informs the microprocessor 24 that the counting is completed.

The microprocessor 24 received this stops the rotating rotor 11 by stopping the operation of the driving motor 29 through the motor driving interface 28, and the first support 4 and the second support 5. The entire clamp portion A including) is returned to the initial state as shown in FIG.

After the return, the first clamp sensor 8 located at the bottom of the clamp portion A monitors whether the clamp portion A has returned to its normal initial position and feeds it back to the microprocessor 24 to control the position.

During or after the return to the initial state, the user completes the bill counting process of the present invention by withdrawing the counted bill.

When the check time is reached while the counting is in progress or the counting is completed and the information according to the counting is to be outputted, the communication modem 35 shares the counting information with the plurality of computers 37 through the communication modem 35. This allows you to efficiently manage information in large or remote locations.

Therefore, according to the small bill counter using the air cylinder of the present invention, the microprocessor that receives the measurement values of the bill detection sensor, the clamp position sensor, the count sensor, and the pressure sensors receives the set value, and the conditions of the bill detection sensor, the count sensor, and the pressure sensor are received. Start counting when this is satisfied,

The microprocessor drives the rotor drive motor according to the measurement of the pressure sensor so that the count of bills is made by the rotor or the pressure of the vacuum pump is properly adjusted by the pressure sensor.

The microprocessor is configured to display the result according to the coefficient on the coefficient display unit, the number setting display unit and the customer display unit,

The microprocessor enables a billing system to receive and receive an aggregated value by counting while communicating with a plurality of computers through a communication modem, thereby enabling stable counting of bills and stable even when pressure changes according to the terrain. Counting is possible and it is possible to systemize several offices where many bills are handled.
