[

The coin detecting sensors 101 and 115 for detecting coin on the auxiliary disk and the rotating disks 140 and 141 detect the conduction of current by the contact of the coin with the ground switch and determine whether or not there is a coin.

The automatic coin sorting apparatus according to the embodiment of the present invention will be described in detail with reference to FIGS. 1 to 6. FIG.

FIG. 2 is a flowchart of an automatic coin sorting process according to an embodiment of the present invention. When a user first applies power to the automatic coin sorting apparatus and starts a sorting and wrapping mode, an operation state and initialization of each sensor, And whether or not the storage box is in the correct position.

FIG. 3 is a screen display of a touch screen according to an embodiment of the present invention. In the touch screen 100, each denomination is displayed on the touch screen 100 so that the user can select the denomination of the packed coin through the touch screen 100. For example, you can select "500 won, 100 won, 50 won, 10 won (won), 10 won" for each category, or provide a touch icon to select all the coins.

When the user selects a category desired to be classified and packaged according to the guidance of the touch screen 100 and then selects the "package start" button, the control unit 120 detects whether or not the coin loaded in the hopper is loaded, And if it is determined that all of the coins are in a normal state, a counting and packing mode for a plurality of denominations coins inserted into the hopper is started.

That is, the calculation section composed of the auxiliary disk 131, the rotating disk 141, the drawing belt 146, the slant conveyor belt 143, etc. is operated by the control section 120, And only the normal coin of the corresponding denomination is loaded on the end of the supply unit, and then the coin is moved to the wrapping unit wrapped in a certain number of units through the wrapping unit.

FIG. 4 is a block diagram of a calculation unit including an output rail and sensors according to an embodiment of the present invention. Referring to FIG. 4, the calculation unit first drives the auxiliary disk motor 130 by a control unit 120 And the coin stacked on the auxiliary disk 140 is supplied to the rotating disk 141. The rotating disk 141 rotates the auxiliary disk 140 by rotating the auxiliary disk 140, The coin supplied to the drawer rail 110 moves along the drawer rail 110 as the drawer belt 146 rotates.

If it is determined that the stacking height of the coins stacked in the rotating disk 141 sensed by the level sensor 116 provided in the rotating disk 141 is greater than a predetermined amount, The driving of the auxiliary disk motor 130 is stopped until the coin stacked on the rotating disk 141 is discharged and the amount of coins discharged is smaller than the set amount.

The control unit 120 determines whether the coin stacked on the rotating disk 141 is normally supplied to the drawing rail 110 while rotating the coins stacked on the rotating disk 141. The first and second front And senses it through the sensors 111 and 112.

The control unit 120 determines that coins exist on the rotating disc 141 through the coin detecting sensor 115. The first and second front sensors 111 and 112 and the coin sensor 114 It is determined that coins are caught in the tiknees 103 that supply coins from the rotating disc 141 to the drawer rails 110.

When it is determined that coins are caught in the teething unit 103, the control unit 120 rotates and rotates the disk rotating motor 131 for a predetermined period of time to remove coins caught in the teething unit 103.

If the first and second front sensors 111 and 112 and the coin sensor 114 are both rotated in the reverse direction after the rotation of the disc rotating motor 131 under the control of the controller 120, , It is determined that there is foreign matter other than coins in the rotating disk 140. [

When the coin which is about to enter the drawing rail 110 from the tikne thread 103 is larger or thicker than the corresponding denomination, the coin received through the tikne thread 103 can not pass through the drawing rail 110 , It is judged that it is caught at the entrance of the drawing rail 110.

That is, when a coin signal is detected for one second or more in the first and second front sensors 111 and 112 and no signal is detected in the material sensor and the coin sensors 113 and 114, It determines that a denomination larger than the denomination coin or the selected coin is caught in the teething unit 103, and rotates the removal motor 134 at a predetermined angle (180 degrees).

The removal cam 144 rotates as the removal motor 134 rotates so that the deflector 117 moves in conjunction with the rotation of the removal motor 134 so that the width of the withdrawal rail 110 becomes as wide as the rotation angle of the removal cam 144 .

As the width of the drawer rail 110 becomes wider due to the movement of the deflector 117, the coin hanging on the teak thread 103 or the coin having a large diameter is discharged to the discharge port 150.

The coin entering the drawing rail 110 through the tiknees 103 is a selected coin or a coin having a smaller thickness or diameter than the selected coin. If the coin is smaller in diameter, it is determined as a different kind of coin, And dropped to the discharge port 150 provided in the rail 110. [

However, if the diameter is the same as the selected denomination, the material sensor 113 passes through the material sensor 113 along the drawing rail 110. The material sensor 113 measures the eddy current value of the coin with the eddy current sensor, .

When the measured value of the eddy current of the material sensor 113 is determined as a normal coin, the controller 120 passes the coin sensor 114 and counts the coin sensor 114, and then loads the coin sensor 114 for wrapping.

The coins loaded in the supply fountain are discharged through the packed coin outlet after packaging if the quantity is aquatic, and the remaining coins are loaded on the corresponding drawer when the amount is less than the purified amount.

If the measured value of the eddy current of the material sensor 113 is determined to be a pseudo-coin rather than a normal coin, the control unit 120 stops the movement of the coin and discharges the coin to the discharge port 150. [

That is, the control unit 120 drives the stop solenoid valve 135 to stop the movement of the coin determined as quasi-coin, and when the stop solenoid 135 is driven, 110 to stop the movement of the moving coinage while rotating the drawing motor 136 in the opposite direction to rotate the drawing belt 146 in the stopping direction and the reverse direction so that the coinage is discharged to the discharge opening 150 And the next coin is continuously moved through the drawing rail 110 as the drawing motor 136 rotates forward.

5 is a diagram showing a coin movement according to an embodiment of the present invention in which a coin movement is performed before a turn of the drawer belt 146. A coin 10 moving along the drawer rail 110 moves in a reverse direction The control unit 120 controls the removal motor 134 to rotate at a predetermined angle 180 ° so that the coin 10 moving in the forward direction moves in the reverse direction and moves to the discharge port 150. At this time, The removal cam 144 rotates as the removal motor 134 rotates and the deflector 117 moves so that the width of the withdrawal rail 110 is reduced by the removal cam 144).

The deflector motor 134 is rotated at a predetermined angle (180 degrees) after the pseudo-coin is discharged and the deflector 117 coupled to the removal cam 144 is returned to its original state, The width is returned to the original state, and the drawing belt 146 is rotated again in the forward direction to sort the next coin.

As described above, when the coin is a coin of a smaller denomination than the denomination selected by the controller 120, a coin with a width larger than a defective coin or a set coin, or a coin coin, the coin is discharged to the outlet 150 The discharged coins are re-supplied to the auxiliary disk 140 through the inclined conveyor belt 143 or discharged to the take-out storage box 160.

FIG. 6 is a block diagram of a switching plate and a take-out storage for defective / quasi-coin processing according to an embodiment of the present invention. When the control unit 120 determines that the coin is denominated coin, 143 are re-supplied to the auxiliary disk 140 by being loaded on the bucket 162 of the auxiliary disk 140.

That is, in the case of the coin type of the differentiating species judged to be smaller than the selected denomination, coins of the differentiated denomination discharged through the discharge port 150 are transferred to the auxiliary disk 140 (FIG. 1) through the inclined conveyor belt 143 and the horizontal conveyor belt 142 , The motor 133 for the inclined conveyor belt and the motor 132 for the horizontal conveyor belt are driven so that the differentiated denomination coin falling down is loaded on the bucket 162 provided in the inclined conveyor belt, (140).

If the coins fallen through the discharge port 150 as determined by the control unit 120 as coin coins having a large coin width or a coin coin of a large width are dropped by the control unit 120 under the control of the controller 120, The switching plate motor 137 is driven so that the switching plate 147 is rotated at a predetermined angle of rotation, and the switching plate motor 137 is driven so as not to be supplied again to the auxiliary disk 130 through the belt 143. [ The falling direction of the defective and wide coin or coin dropped by the switching plate 147 through the outlet 150 is guided to be taken out and stored in the storage box 160.
