Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1-7, the coin identification device suitable for the coin exchange paper money equipment comprises a box body 1, a coin slot 2, an electronic screen 3, a paper money slot 4, a coin taking slot 5, a coin storage box 10, a first conveyor belt 11, a track 12, an electromagnetic ring 13, a coin falling slot 14, a first baffle 15, a second baffle 16 and a second conveyor belt 17; a pressure sensor 18, an unidentified coin hopper 19, an identified coin hopper 20 and a system processor.
Example (b):
the utility model provides a coin recognition device suitable for coin exchange paper currency equipment, includes box 1, sets up electronic screen 3, slot 2, paper currency mouth 4 on box 1, gets coin slot 5, and electronic screen 3 accepts the change coin instruction and sends the suggestion and open the slot, and the operator puts into the slot and closes the door with mixed various coins according to the suggestion. After the coin is inserted, the device starts counting coins and displays the number and the denomination of each coin input on the electronic screen. In the process of counting coins, the device puts the unidentified coins into the coin taking port, and converts the counted coins into paper money to be output from the paper money port.
An operator puts coins into the delivery port 2, the lower part of the coin port 2 is communicated with the coin storage box 10, the gap between the coin storage box 10 and the first conveyor belt 11 is ensured to be the thickness of one coin (the thickness of one corner of the fourth set of RMB is the thickest one, and the five-corner and one-coin can be ensured to smoothly fall down), so that the coins falling into the first conveyor belt 11 from the coin storage box 10 are arranged in a straight line after the first conveyor belt 11 runs, the lower part of the coin storage box 10 is connected with the first conveyor belt 11, when the coin counting work starts, the first conveyor belt 11 and the second conveyor belt 17 start running, the coin storage box 10 sequentially puts the coins into the first conveyor belt 11, when the first conveyor belt 11 runs and runs, the coins are sent into the track 12, when the coins are transported in the track 12, because the track 12 is of a wave-shaped structure, the characteristics of unevenness are realized, so that the coins gradually change from a horizontal state to a vertical state (the width of the track gradually narrows down along the coin moving direction, for the transition when changing from horizontal state to vertical state when coin is carried, mainly for the state of the vertical transportation of adaptation coin), the kinetic energy of coin operation is mainly provided by the difference in height of first conveyer belt and track, the coin becomes vertical state back and is passed through electromagnetic ring 13 by guide rail 12 and cuts the magnetic induction line that electromagnetic ring 13 produced, different coins are vertical to pass through electromagnetic ring cutting magnetic induction line, influence the big or small degree of electric current through different coin cutting magnetic induction lines and distinguish true coin or false coin, distinguish for false coin, then drop coin mouth 14 will open, the coin will fall into unidentified coin storage mouth 19 and retreat to get coin mouth 5.
A second conveyor belt 17 is arranged below the guide rail 12, a first baffle 15 is arranged around the second conveyor belt 17, a plurality of pressure sensors 18 are arranged below the second conveyor belt 17, and a second baffle 16 is arranged below the second conveyor 17. The coins pass through the electromagnetic ring 13 and then are made to do horizontal projectile motion from the tail end of the guide rail 12, the speed of the coins in the vertical direction during the horizontal projectile motion is increased from zero, and after the coins impact the second conveyor belt 17, different pressures can be generated due to different coins. At this point, the plurality of pressure sensors 18 transmit a plurality of pressure signals to the system processor, which begins counting coins. When the pressure signal generated by the coin striking the second conveyor 17 is not recognized by the system processor, the system processor controls the second singulator to rotate to the left to convey the coins whose pressure is not recognized from the second conveyor 17 and the second singulator 16 to the unidentified coin store opening 19, and then the second singulator 16 is returned to its original position. The coins in the coin storage box 10 are counted and checked continuously through the continuous operation of the first conveyor belt 11 and the second conveyor belt 17, and after the coins are counted, the system processor ejects paper money from the paper money port 4 according to the counted denomination of the coins.
The coin is thrown from the end of the track 12, the speed of the coin in the vertical direction is zero when the coin just leaves the end of the track, the different coins start to have the speed in the vertical direction under the action of gravity and increase continuously due to the different masses of the different coins, and the change amount of the coin speed can be described by a momentum equation:
i.e. by
. That is, the final speed of the free fall of different coins under the same altitude difference is the same, the coins fall into the second conveyor belt after passing through the free fall, the second conveyor belt is provided with the first baffle all around, and the first baffle can prevent the coins from falling outside the second conveyor belt.
A pressure sensor is arranged below the second conveyor belt and the coin, at the instant of falling onto the second conveyor belt, exerts an instantaneous pressure on the conveyor belt. The pressure sensor under the conveyor belt captures the instantaneous pressure and identifies coins of different denominations according to the corresponding pressure magnitude. The instantaneous pressure at which the coins fall onto the second conveyor belt is related only to the speed of the coins in the vertical direction and can be expressed by the formula:
the speed v is the final speed of the coin in the vertical direction of the free falling body, and the vertical speeds v of different coins are the same, soThe denomination of a coin can be distinguished according to the mass of different coins, with the magnitude of its instantaneous pressure being dependent only on mass.
