As shown in FIG. 7, each component is controlled by the central controller 100, and the configuration related to the control of the central controller 100 is calculated by the central controller 100. A display unit 102 for displaying the amount of the coin, an alarm unit 104 indicating a state of jamming, etc. of the coin, a first motor 160 for transmitting rotational force to the dropper plate 180, and a fu A second motor 162 for transmitting power to the sheer 150, a position detecting unit 190 for detecting a position of the dropper plate 180, a state detecting unit 192 for detecting a state of the coin, It comprises a size detecting unit 194 for detecting the size of the coin, and a proximity sensor 196 for detecting whether the coin is fed into the alignment unit 140 from the hopper 120.

The first motor 160 is connected to the central axis of the dropper plate 180 to transfer power to the dropper plate 180, the second motor 162 is connected to one side of the rotary arm 130 to power the arm. To pass.

As illustrated in FIG. 6, the position detecting unit 190 is disposed in the dropper plate 180 to adjust the position of the dropper plate 180 by the position detecting groove 184 formed in the dropper plate 180. Detect and count the number of coins.

As illustrated in FIG. 6, the state detecting unit 192 detects a state of a plurality of coins being installed and transported on the transfer path 116 of the dropper plate 180, for example, using an RF sensor or the like. The coin is irradiated to the radio wave and the component of the coin, ie, the material, is detected by the frequency of the reflected radio wave.

6 and 8, the size detecting unit 194 is installed in the transfer path 116 of the dropper plate 180 to detect a state of a plurality of coins being transferred, for example, a main plate. The light emitting element 194a is embedded at the side 112, and a plurality of light receiving elements 194b are embedded in the subplate 114 at the corresponding position to detect the size of the coin.

That is, the plurality of light receiving elements 194b are arranged at a predetermined height from the lower surface of the transport path 116. For example, the light receiving element 194b element located at the top detects the largest 500 won coin. Then, the light receiving element 194b of the next position senses 100 won coins of the next size, and in turn installs each light receiving element 194b at a height corresponding to the diameter of the 10 won and 50 won coins.

Proximity sensor 196 is installed inside the alignment unit 140 corresponding to the position of the outlet of the hopper 120 detects the input of a plurality of coins, the alignment unit 140 and the dropper 182 abuts Installed in the position senses the presence of coins remaining in the alignment unit 140.

According to this configuration, the coin is injected into the hopper 120 is inserted into the groove 144 of the alignment unit 140, when the proximity sensor 196 detects this, the central control unit 100 to push the pusher 150 Control to align the alignment vertically.

That is, the pusher 150 receives the power according to the rotation of the second motor 162 through the rotary arm 130 to move back and forth several times along the groove 144 of the alignment unit 140 stacked coins. Are aligned vertically, and finally, as shown in FIG. 2B, the coin 200 is pressed to inject into the dropper plate 180.

At this time, the central control unit 100 detects the current amount of the second motor 162 and the current amount increases greatly, that is, when the pusher 150 stops without moving by the resistance of the coin 200, The first motor 160 is driven to start counting coins.

When the counting of coins is completed and the rotation of the dropper plate 180 is stopped, in order to position the dropper 182 in the alignment unit 140, the position sensing unit 190 is formed in the dropper plate 180 When the proper position of the dropper plate 180 is sensed through the 184, the central controller 100 stops the first motor 160, so that the dropper plate 180 aligns any one of the plurality of droppers 182.

That is, when the coin is dropped into the dropper plate 180 and is dropped into the transport path 116 by the dropper 182, the position detecting unit 190 may detect this by the position of the dropper 182. If the state detection unit 192 does not detect the insertion of the coin occurs, the central control unit 100 determines this as an error and stops the dropper plate 180.

At this time, the central control unit 100 notifies the user of the error of the device through the alarm unit 104.

Hereinafter, referring to FIG. 9, the operation of the high-speed coin counting device 10 capable of sorting according to an exemplary embodiment of the present invention will be described.

9 is a flowchart illustrating a method of operating a high speed coin counting device according to an embodiment of the present invention.

First, when a large amount of coins, for example, less than 20 different types of coins are randomly input to the hopper 120, the hopper 120 discharges the coins injected through the outlet formed in the lower portion to the alignment unit 140. Then, the proximity sensor 196 installed in the groove 144 of the alignment unit 140 detects the input of the coin (step S901).

At this time, the central controller 100 drives the second motor 162 with a time difference to align the coins vertically (step S902). That is, when the power is transmitted to the pusher 150 through the rotary arm 130 connected to the second motor 162 as the second motor 162 is driven, the pusher 150 of the alignment unit 140 The coins are aligned back and forth several times along the groove 144, and finally, the coins are pressed to advance.

The central controller 100 detects that the current of the second motor 162 is greatly increased as the pusher 150 is stopped by the coin and determines that coin alignment is completed (step S903).

When the central controller 100 rotates the dropper plate 180 by driving the first motor 160 as the coin alignment is completed (step S904), the coin injected into the dropper plate 180 is dropped by the dropper 182. The feed path 116 is transported inside the main plate 112.

The coin is transported along the transfer path 116 is detected by the state detection unit 192 (step S905), for example, by irradiating the radio wave to the coin using an RF sensor or the like frequency of the radio wave reflected According to detect the material of the coin.

In addition, the coin transported along the transport path 116 is detected by the size detecting unit 194, that is, the amount of coins (step S906), for example, in the vertical direction of the transport path 116. A plurality of light receiving elements 194b are formed at positions corresponding to the size of coins, and the corresponding amount is detected by detecting the size of coins put in accordance with the detection signal of each light receiving element 194b.

As such, when the amount corresponding to each coin is detected and the number of coins put by the position detecting unit 190 is detected, the central controller 100 calculates the total amount of coins put and displays them on the display unit 102. (Step S907).

When the counting of all the coins is finished in this way, the proximity sensor 196 installed on the dropper plate 180 side of the alignment unit 140 detects the presence of coins in the alignment unit 140 (step S908), For example, if a coin movement is not detected at regular time intervals, it detects that there is no coin to count.

If the central control unit 100 determines that there are no coins to count, the position detecting unit 190 senses the proper position of the dropper plate 180, and at the point when the dropper 182 is positioned on the alignment unit 140. The first motor 160 is stopped to place the dropper plate 180 at an appropriate position (step S909).

This operation is to prevent the coin aligned in the alignment unit 140 during the next coin counting to be introduced into the dropper plate 180 before counting.

With this configuration, the high speed counting device 10 according to the present invention can count coins put in large quantities at high speed.

As described above, according to the present invention, the high-speed coin counting device capable of sorting coins is vertically aligned by a pusher, and the dropper feeds the coins into the transfer path according to the rotation of the dropper plate, thereby transferring the coins by centrifugal force. The path is transported along a curve and simultaneously detects the type and state of coins, so that even if a large number of coins are put in a large amount, the counting of the coins and the calculation of the corresponding amount of money can be performed at high speed.

In addition, the present invention forms a position detecting groove in the dropper plate, and by installing a position detecting unit inside the coin counting module, after passing through the dropper plate of the coin, the recognition unit does not detect the coin due to pinching of coins, etc. By stopping the rotation of the dropper plate, it is possible to prevent errors caused by poor coin and damage to the device.
