Abstract

The present invention relates to a method that utilizes step losing of a step motor to correct centering of banknotes. When banknotes are inserted into the passage of a receiving device, the sensor of the detecting device can detect the insertion of banknotes in the passage, and the banknote-pressing wheel set of the driving device will press the banknotes and the driving part will actuate the driven wheel set to drive the banknotes to move. Next, the step motor in an adjustment and alignment device actuates the driving part according to the preset step angle to make two adjustment elements oppositely abut against the banknotes to turn them parallel input to the center, and simultaneously allow the banknote-pressing wheel set to release banknotes. If the resistance of adjustment elements from the banknotes is greater than the thrust generated by the step motor to actuate the driving part to drive the adjustment elements, the step losing of the step motor causes failure to continue pulling the banknotes. It is the step losing that can be utilized until the step motor reaches a preset step angle and makes a return movement, and then the banknote-pressing wheel set of the driving device resumes pressing the banknotes and the banknotes are driven to move by the driven wheel set, thereby achieving effects of simple structure, precise alignment and low cost.

Description

Method for using the stepping motor to lose the step of guiding the banknote

The present invention provides a method for centering a banknote with a stepping motor, in particular, the stepping motor of the adjusting alignment device is used to drive the transmission portion to push the two adjusting components relatively against the banknote formation center. If the adjustment component receives the thrust of the banknote greater than the thrust generated by the stepper motor, the stepper motor may be out of step and the banknote may not be continuously pushed back.

According to the current development of social civilization and technology, not only has it accelerated the pace of people's lives, but the requirements for quality of life have become more convenient and faster. Therefore, in many public places, there are automated sales machines, money detectors or other papers. In addition to the significant savings in personnel employment costs, the banknote receiver station, with the help of automated banknote receivers, requires more additional features as more types of goods are sold.

Since counterfeit banknotes are often produced in large quantities by many unscrupulous people and widely used in the market, the banknote receivers on the market need to identify the authenticity before receiving the banknotes. The general practice is based on the machine. There are identification devices inside the station. However, most of the current banknote receivers are only suitable for banknotes of a single width. However, due to the different sizes of banknotes issued in various countries, different types of banknotes are used. The position of the designed safety feature will also change. Therefore, the banknote received by the banknote receiver station must be accurately identified by the identification device. When the user inserts the banknote, the banknote can be used. Can be skewed or offset, causing the security features on the banknote to be inaccurately identified by the location of the identification device, and the banknote receiver station will withdraw the banknote, so the user needs to repeat Inserting banknotes is extremely inconvenient and troublesome to use.

Furthermore, although various manufacturers have already proposed various centering or adjusting alignment devices to be applied to the banknote receiving platform, in order to adjust the banknotes to align with the position of the identification device, the alignment mode is driven by the roller. The banknote is displaced inwardly, and the clamping arm at the two sides of the channel is relatively pushed against the two side edges of the banknote to form a center, and the sensor detects the resistance of the banknote feedback, and then stops the clip. The relative displacement of the arm causes the banknote to be centered. However, when the banknote is inserted, the width and offset direction of the banknote must be detected by the sensor first, and the control circuit calculates that the motor needs to drive the two clamp arms. The distance, but the higher the accuracy required for the motor to drive the clamp arm to push the banknote into the center, the circuit design of the control circuit with the sensor will be more complicated, and the overall installation cost is relatively increased. Designed to focus on the overall mechanism of the centering device, the cost, and the correct position of the banknotes, in order to meet the actual application of the banknote receiver platform, that is, the direction of research and improvement for those engaged in this industry. Where.

Therefore, the inventors have designed and produced such information based on the problems and shortcomings in the use of the banknote receiver platform. The relevant materials have been evaluated and considered by various parties, and the research and development experience of the industry has been continuously tried and modified. The invention patent was born using the method of stepping motor out of step and guiding the banknote.

The main purpose of the present invention is to have a banknote input in the sensor detecting channel of the detecting device, the banknote wheel set of the transmission device will hold the banknote, and the driving part drives the wheel set to drive the banknote Displacement, and then using the stepping motor of the adjustment alignment device to drive the transmission portion according to the preset number of steps, so that the two adjustment elements are pushed against the banknotes and returned to the parallel input to form a center, and at the same time, the banknote wheel sets to release the paper. Banknotes, if the adjustment component is subjected to the resistance of the banknotes greater than the thrust generated by the stepper motor drive, the stepper motor can be used to lose the step and cannot continue to push the banknotes until the preset step angle is reached, and then the action is returned. After the banknote wheel set of the transmission device is restored to the banknote, the banknotes are driven to move the banknotes, thereby achieving the advantages of simple structure, accurate alignment and low cost.

The secondary object of the present invention is to use a stepping motor when the stepping motor is continuously operated, if the resistance of the adjusting component to the banknote reaction is greater than the thrust generated by the stepping motor driving (generally 4 to 8 g). Out of step state, so that the two adjusting components can not continue to push the banknotes until the pulse signal input to the stepping motor of the control circuit reaches a preset number of steps, the driving portion can be driven to retract the adjusting component, It is convenient for the identification device to perform the subsequent banknote identification and the receiving device to receive the action, and can avoid the use of the centering or adjusting the alignment device to detect the banknote width and the offset direction by using the sensor, so as to drive the motor to drive the two clamp arms Relatively pushing against the banknotes, the circuit design of the control circuit with the sensor is more complicated, and the overall installation cost is relatively increased.

Another object of the present invention is to shift the banknote to the left or to the right, and the stepping motor of the adjusting device can drive the transmission portion to make one of the adjusting components. Pushing on the side of the banknote (such as the left side), the resistance of the banknote is less than the thrust generated by the adjustment component, so the adjustment component will push the banknote to move toward the other adjustment component, and wait for another When an adjusting component is pushed against the other side of the banknote (such as the right side), the two adjusting components can be pushed inwardly to the banknotes of various widths for width adjustment, thereby turning the banknotes back into parallel Enter the path to form a centered state.

In order to achieve the above objects and effects, the technical means and the configuration of the present invention will be described in detail with reference to the preferred embodiments of the present invention.

Please refer to the first, second, third, fourth, fifth, sixth and seventh figures, which are respectively a flow chart of the steps of the present invention, a stereoscopic appearance of the preferred embodiment, a partial exploded view of the receiving device, and a stepping motor. A partial perspective view, an exploded perspective view of a banknote wheel set, a front view and a side cross-sectional view of a preferred embodiment, as is apparent from the drawings, the present invention includes a body 1 and a receiving device 2, wherein the body The front panel 11 has a socket 111, and the receiving device 2 positioned inside the main body 1 has a passage 20, and the passage 20 is connected to the socket 111 of the panel 11.

Further, the receiving device 2 is internally provided with a transmission device 21, an adjustment alignment device 22, a detection device 23 and an identification device 24 corresponding to the channel 20, and a storage device 25 is disposed at the rear of the channel 20, wherein the transmission device 21 includes at least one set of driving parts 211 and driving wheel sets 212 And a banknote wheel set 213, and a gear set 2111 having a plurality of shafts 2110 is connected to one side of the driving part 211, and each of the shafts 2110 is respectively provided with a plurality of rollers 2121 for driving the wheel set 212, and the banknote wheel The group 213 is located above the other side of the channel 20 with respect to the driving wheel set 212. The banknote wheel set 213 has a rotating shaft 2131 for the solenoid valve 2132 to be rotated at an angle, and is located before and after the solenoid valve 2132. A banknote roller 2133 is provided at the side for the rotary shaft 2131 to be driven or released to press the banknote 3 (as shown in the eighth, ninth, tenth, and eleventh figures).

However, the adjustment alignment device 22 is a stepping motor 221 having at least one set of output shafts 2210, a transmission portion 222, and an adjustment member 223. The adjustment alignment device 22 preferably has two sets of stepping motors 221, and A power transmission shaft 2210 of the stepping motor 221 is connected to a transmission portion 222 which may be a gear set (not shown) or a rotary member 2221, and the adjustment member 223 has an opposite jaw shape arm 2231, and the clamp arm A shaft hole 2230 for the sliding rod 2232 is disposed at the front and rear sides of the bottom of the 2231, and a rotating member 2221 for the transmission portion 222 is disposed between the two shaft holes 2230 to move the clamping arm 2231. The interlocking portion 2233 which is displaced inside or outside, and the elastic member 2234 which can be elastically deformed by the movable arm 2231, can drive the adjusting portion 223 to drive the adjusting member 223 relatively inward or by the stepping motor 221 The action of adjusting the width outward.

In addition, the detecting device 23 has at least one control that can be a circuit board The circuit 230 is provided with a plurality of sensors 231 on the control circuit 230 for detecting that the banknote 3 is activated or stopped by the channel 20 to drive the banknote 3 to move and adjust the alignment device 22 to operate. The driving unit 211 of the transmission device 21 is driven to drive the wheel set 212 to drive the banknote 3 to the position of the identification device 24, and the identification device 24 is a sample identification module 241 including the authenticity and the denomination of the banknote 3. The sample identification module 241 has a plurality of light emitters and light receivers (not shown) disposed on the control circuit 230. The storage device 25 has the function of recognizing the identification device 24 as a true The banknote 3 of the banknote is pressed into the banknote crucible 252 to receive the pressing mechanism 251.

The stepping motor 221 of the adjusting device 22 is a rotor 2211 and a stator 2212 including a gear-shaped protrusion. The rotor 2211 is provided with a power output shaft 2210, and the two rotors 2211 are magnetized in the direction of the output shaft 2210. An N pole or an S pole is formed, and a plurality of stators 2212 are respectively wound with coils (not shown), and a driver (not shown) of the control circuit 230 outputs a desired pulse signal. The stator 2212 of the stepping motor 221 performs switching of the control excitation operation, and even if the coils on the stator 2212 are magnetized to the same polarity after passing through the switching current, the excitation phase can be sequentially switched, thereby controlling the stepping of the stepping motor 221. The angle = 360 degrees / (the number of coil groups x the number of salient poles of the rotor 2211), so that the angle at which the stepping motor 221 operates can be controlled by controlling the number of input pulse signals.

The operating characteristics of the stepping motor 221 can be divided into two types: stalling and out-of-step. The reason for the stalling is that the rotor 2211 stops rotating because the speed of the rotation of the rotor 2211 of the stepping motor 221 cannot keep up with the speed of the magnetizing of the stator 2212. While the coil on the stator 2212 is still in the excitation, the stator 2212 is excited by the pulse signal, so the coil does not burn out; the reason for the out-of-step is that the stepping motor 221 can operate synchronously with the pulse wave. However, it may not be able to run synchronously with the pulse wave due to the rapid change of speed or overload, and the output torque is inversely proportional to the rotational speed, so the torque drop cannot load the external load, causing a small slippage, which cannot be combined with the pulse wave. The state of simultaneous operation is called out of step.

Therefore, the method for positioning the stepless motor of the stepping motor is preferably applied to the banknote receiver, but in practical applications, it is not intended to limit the scope of the patent of the present invention, and may also be applied. It can be used in the automatic vending machine, game machine or other consumer system that can provide goods purchasing and consuming services. The main body 1 can be placed inside the main body of the banknote receiver, and can also be used together with the identification device 24 as a banknote identification machine. The use of the receiving device 2 can be connected to the host through the control circuit 230 of the detecting device 23 for data signal and power transmission, thereby providing the banknote receiver with the function of authenticity and face value identification, receiving and exiting of the banknote 3 .

In the following, when the method of using the stepping motor to take the step of guiding the banknotes by the stepping motor is utilized, the following steps are implemented:

(101) Start.

(102) The sensor 231 of the detecting device 23 detects that there is a banknote 3 input in the channel 20.

(103) The banknote wheel set 213 of the transmission device 21 presses the banknote 3, and the driving wheel set 212 is driven by the driving portion 211 to drive the banknote 3 to be displaced to a predetermined position.

(104) The stepping motor 221 of the adjusting alignment device 22 drives the transmission portion 222 according to the preset number of steps to rotate the two adjusting members 223 relatively inward, and is pushed back by the adjusting member 223 to the two sides of the banknote 3 The centering is formed in parallel, while the banknote wheel set 213 is displaced to release the banknote 3.

(105) Is the adjustment element 223 subjected to the resistance of the banknote 3 greater than the thrust generated when the stepping motor 221 drives the transmission portion 222 to drive it? If not, step (104) is repeated, and if YES, step (106) is performed.

(106) The step of the stepping motor 221 is lost, and the banknote 3 cannot be continuously pushed until the preset step angle number is reached, and the driving portion 222 is driven to retract the adjusting member 223.

(107) After the banknote wheel set 213 resumes pressing the banknote 3, the driving unit 211 drives the driving wheel set 212 to drive the banknote 3 to be displaced.

(108) End.

It can be clearly seen from the above-mentioned implementation steps that when the user inserts the bill 3 from the socket 111 of the main body 1 panel 11 by hand, the bill can be made into 3 Into the channel 20 of the receiving device 2, until the banknote 3 is displaced to the sensor 231 of the detecting device 23 adjacent to any of the displacement sensors 2311 of the socket 111, the sensor 231 is triggered, and The control circuit 230 detects that there is a banknote 3 input in the channel 20, and the solenoid valve 2132 of the banknote wheel set 213 of the transmission device 21 is released to the rotary shaft 2131, so that the banknote roller 2133 presses down the banknote 3 At the same time, the driving unit 211 is also started to operate synchronously, and the roller 2121 driving the wheel set 212 is driven to move the banknote 3 to a predetermined position, and the banknote 3 is displaced to the position of the identification device 24, and then the sampling identification module 241 is used for control. The circuit 230 performs the identification of the authenticity and the face value of the banknote 3. If the sample identification module 241 determines that the banknote 3 is a genuine banknote according to the comparison result, the banknote 3 is displaced to the storage device 25 by the pressing mechanism. The 251 is pressed into the banknote 252 for receiving. If it is judged that the banknote 3 is a counterfeit banknote according to the comparison result, the banknote 3 is caused to exit toward the socket 111 of the panel 11.

Please also refer to the eighth, ninth, tenth, and eleventh drawings, which are schematic diagrams of the top view of the banknote offset in the channel of the receiving device, and the top view of the alignment device before the paper is adjusted. The top view of the paper banknote and the top view of the paper banknote after the centering is formed. As is clear from the figure, when the user puts the banknote 3 to the left or the socket 111 of the panel 1 of the main body 1 or When the offset is inserted to the right, the detector 231 adjacent to the socket 111 can detect the width and the offset direction of the banknote 3, and the driving part 211 of the transmission device 21 drives the driving wheel set. 212 to bring When the banknote 3 is displaced, and the banknote 3 trigger sensor 231 is adjacent to the stop sensor 2312 of the identification device 24, the banknote 3 is stopped, and the banknote 3 is placed at the adjustment alignment device 22 Between the adjusting elements 223, the control circuit 230 of the detecting device 23 is used to control the stepping motor 221 of the adjusting and aligning device 22 to start the operation, and the solenoid valve 2132 of the banknote wheel set 213 is also driven to push the rotating shaft 2131. The bill press wheel 2133 is displaced upward to release the bill 3.

The control circuit 230 of the detecting device 23 controls the stepping motor 221 to drive the transmission portion 222 to drive the two adjusting members 223 to be relatively inwardly displaced according to a preset number of steps, or may be driven by the two sets of stepping motors 221 respectively. When the adjusting member 223 is relatively inwardly displaced, the clamping arm 2231 of the second adjusting member 223 can be used to push the width adjustment between the two sides of the bill 3, even if the bill 3 is turned back to the parallel input path. a preset state, and the preset number of steps of the stepping motor 221 controlled by the control circuit 230 can be a fixed value to ensure that the two adjusting elements 223 can be pushed inward relative to each other when driving the transmission portion 222 The width adjustment action is made at the two sides of the banknotes 3 of various widths.

Furthermore, when the adjustment alignment device 22 adjusts the banknote 3 to form a center, if the stepping motor 221 continues to operate, the clamp arm 2231 of one of the adjustment members 223 is first pushed to the side of the offset banknote 3 (As in the left side), since the resistance of the banknote 3 reaction is smaller than the thrust generated when the stepping motor 221 drives the transmission portion 222 to drive the adjustment member 223, the adjustment component 223 will be pushed against the banknote 3 in the direction of the other adjusting member 223, and the clamping arm 2231 of the other adjusting member 223 is pushed against the other side of the banknote 3 (such as the right side), and the second adjustment can be made. The clamping arm 2231 of the component 223 is relatively pushed against the two sides of the banknote 3. At this time, if the resistance of the two adjusting component 223 by the banknote 3 is greater than the thrust generated by the driving motor 222 of the stepping motor 221 ( Generally, it is 4~8g), and the stepping motor 221 can be out of step state, so that the two adjusting elements 223 cannot continue to be pushed relatively inwardly to the banknote 3 until the driver of the control circuit 230 is input to the stepping motor 221 After the pulse signal reaches the preset step angle, the stepping motor 221 drives the transmission portion 222 to cause the two adjusting members 223 to be relatively outwardly displaced for retracting action, and restores the banknote wheel set 213 of the transmission device 21 to the original The position of the banknote 3 is pressed, and then the driving unit 211 drives the driving wheel set 212 to move the banknote 3 to the position of the identification device 24 for subsequent authenticity and face value identification. If the sampling identification module 241 determines the banknote according to the comparison result. 3 is a real banknote, it will drive the banknote 3 to the storage device 25 Set the action to receive.

Therefore, the present invention is directed to driving the transmission portion 222 by the stepping motor 221 of the adjustable alignment device 22 to cause the two adjustment members 223 to be pushed against the banknote 3 to be returned to the parallel input path, and the adjustment member 223 is subjected to paper. The resistance of the banknote 3 is greater than the thrust generated by the stepping motor 221 driving the transmission portion 222, and the stepping motor 221 can be out of step and cannot continue to push the banknote 3 until the preset step angle is reached. Drive transmission 2 22, the two adjusting elements 223 are retracted, such that the stepping motor 221 is out of step to ensure that when the driving portion 222 is driven, the two adjusting members 223 can be pushed relatively inwardly to the banknotes 3 having various widths. Width adjustment action, and can avoid the use of the center or adjust the alignment device to detect the width and offset direction of the banknote 3 by using the sensor, so that the driving motor can drive the two clamping arms to push against the banknote 3 The circuit design of the control circuit and the sensor is more complicated, and the overall installation cost is relatively increased, thereby achieving the advantages of simple structure, simple operation and low cost.
