Description

Technical Field

[0001] The utility model relates to the technical field of currency counting and verifying machines, in particular to a currency counting and verifying machine with an invertedly installed magnetic sensor capable of resisting electromagnetic interference and infrared interference. Background Art

[0002] With the development of economy, the application of currency counting and verification machines in people's daily life is very extensive, especially in some cash registers and financial places. In the existing currency counting and verification machines, the currency verification component is often set below the currency verification channel, and the banknotes are verified from below the currency verification channel. Since the motor and transformer are usually installed at the bottom of the currency counting and verification machine, there is a coil inside the currency verification magnetic sensor, which will also generate a magnetic field. The back cover is not protected, and the external magnetic field is very sensitive to its interference reaction. There is a problem of magnetic field interference during use. The magnetic field generated by the motor and transformer affects the stability of the magnetic sensor waveform, especially for Taiwan banknotes. This problem is more serious and difficult to solve. In addition, when multiple patch infrared sensors are working, adjacent infrared light sources will cross each other, resulting in inaccurate infrared judgment, affecting the accuracy of banknote verification. In view of this, how to improve and optimize the structure of the existing Taiwan banknote counting and verification machine, solve the problems of anti-electromagnetic interference and anti-infrared interference, and realize accurate banknote verification has become a technical problem that needs to be solved. Summary of the invention

[0003] In view of the above shortcomings, the utility model provides a paper money counting and checking machine with an inverted magnetic sensor capable of resisting electromagnetic and infrared interference.

[0004] The utility model discloses a paper money counting and verifying machine with an inverted magnetic sensor, comprising: a frame assembly, a transmission assembly and a paper money verifying assembly.

[0005] The rack assembly includes a banknote plate, a light rack, and a receiving rack. The banknote plate is connected to the receiving rack, and the light rack is installed above the receiving rack.

[0006] The transmission assembly includes a transmission shaft, a wool wheel shaft and a motor. The wool wheel shaft is located below the receiving frame, the transmission shaft is located above the receiving frame, and the motor is connected to the transmission shaft.

[0007] The banknote verification component includes at least one pair of magnetic sensors and infrared sensors, and the infrared emitting components of the magnetic sensors and the infrared sensors are installed on the lamp frame and located above the receiving frame;

[0008] A plurality of through holes are provided on the receiving rack. After assembly, the lower part of the transmission wheel on the transmission shaft and the upper part of the hair wheel on the hair wheel shaft after passing through the corresponding through holes are pressed and rolled to roll out the banknotes between them. The infrared emitting components of the magnetic sensor and the infrared sensor are located directly above the hair wheel shaft and correspond to the opening position of the receiving rack so as to verify the banknotes from top to bottom.

[0009] The transmission shaft is provided with a left transmission wheel and a right transmission wheel which are separated from each other, the hair wheel shaft is provided with a left hair wheel, a middle hair wheel and a right hair wheel which are separated from each other, and the magnetic sensor and the infrared sensor are installed at a position between the left transmission wheel and the right transmission wheel; the through holes on the receiving frame are divided into a left through hole, a middle through hole and a right through hole, the left transmission wheel and the left hair wheel passing through the left through hole are pressed and rolled for transmission, and the right transmission wheel and the right hair wheel passing through the right through hole are pressed and rolled for transmission.

[0010] Each of the through holes corresponds to one or more sets of magnetic sensors and infrared sensors.

[0011] The infrared sensor includes an infrared receiving component, an infrared transmitting component, an upper light-transmitting protective isolation cover and a lower light-transmitting protective isolation cover. After installation, the upper light-transmitting protective isolation cover covers the infrared transmitting component installed on the lamp holder, and the lower light-transmitting protective isolation cover covers the infrared receiving component installed on the receiving frame. The infrared light of the infrared transmitting component penetrates through the corresponding through hole on the receiving frame and then enters the corresponding infrared receiving component; the upper light-transmitting protective isolation cover and the lower light-transmitting protective isolation cover are both provided with small holes for the infrared light source to penetrate.

[0013] The frame assembly also includes a bridge connected to the outside of the receiving frame to facilitate the banknotes to slide out and be collected.

[0014] The lamp stand is also provided with a lamp stand cover plate.

[0015] The motor and the transformer are arranged below the receiving frame.

[0017] An upper anti-infrared interference partition is provided on the infrared emitting component, and a lower anti-infrared interference partition is provided on the infrared receiving component.

[0018] After adopting the above structure, the utility model has the following characteristics:

[0019] 1. The magnetic sensor is installed upside down, which solves the problem that the original magnetic sensor is installed below the banknote passage, on the same plane as the motor and transformer. The electromagnetic field generated by the motor and transformer when powered on interferes with the magnetic field of the magnetic sensor, causing the magnetic sensor to produce an erroneous waveform, resulting in banknote counting alarms and inability to distinguish between real and fake banknotes.

[0020] 2. When the patch infrared sensor is powered on, adjacent infrared light sources will cross each other, resulting in inaccurate infrared judgment. The infrared receiving component and the infrared transmitting component are both equipped with an upper light-transmitting protective isolation cover and a lower light-transmitting protective isolation cover to prevent the infrared light sources from crossing each other. A small hole is opened in the upper light-transmitting protective isolation cover and the lower light-transmitting protective isolation cover, so that the infrared light sources will not cross each other and will not cause mutual interference between the light sources, thereby achieving the independence of the upper and lower infrared light sources and ensuring accurate infrared banknote verification;

[0021] In this way, the utility model can count and verify the banknotes stably, so that the machine can be used without errors, especially for the banknotes of Taiwan, China. In addition, the utility model can also verify other banknotes, and the application range is very wide. Therefore, the utility model has the characteristics of anti-electromagnetic and infrared interference, high precision, high efficiency, strong stability, wide application range, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] A plurality of through holes 31 are provided on the receiving frame 30. After assembly, the lower portion of the transmission wheel 41 on the transmission shaft 40 and the upper portion of the hair wheel 51 on the hair wheel shaft 50 that passes through the corresponding through hole 31 are pressed and rolled to roll out the banknotes between the two. The magnetic sensor 60 and the infrared emitting component 71 of the infrared sensor 70 are located directly above the hair wheel shaft 50 and correspond to the position of the opening 31 of the receiving frame 30 so as to inspect the banknotes from top to bottom.

[0034] The infrared sensor 70 includes an infrared receiving component 72, an infrared transmitting component 71, an upper light-transmitting protective isolation cover 73 and a lower light-transmitting protective isolation cover 74. After installation, the upper light-transmitting protective isolation cover 73 covers the infrared transmitting component 71 installed on the lamp holder 20, and the lower light-transmitting protective isolation cover 74 covers the infrared receiving component 72 installed on the receiving frame 30.
