As shown in Figure 1, a coin intelligent sorting and counting device includes a sorting cylinder, a drive spindle 14, a motor room 26 and a collection device, and multi-layer sorting chambers are arranged up and down in the sorting cylinder, specifically: the sorting chamber includes The first sorting chamber 12 , the second sorting chamber 19 and the third sorting chamber 22 are arranged in sequence up and down. The sorting chambers on each floor are separated into coins of different denominations, and the bottom of each classifying chamber except the bottommost sorting chamber is provided with a separation partition, specifically: the separation partition includes the top and bottom sequentially arranged The first separating spacer 16 and the second separating spacer 20 . And the upper layer of separation partition is provided with a sieve hole for the coins that cannot be separated from this layer to flow into the classification chamber of the next layer to continue to separate. Bottom plate 24. The top of the uppermost described sorting chamber is provided with loam cake 13, and described loam cake 13 is provided with the charging port that adds the coin that needs sorting and counting to the described uppermost classifying chamber, the side of each layer described sorting chamber The walls are respectively provided with outlets.

Described motor chamber 26 is below the described classifying chamber of the lowest floor, and in described motor chamber 26, is provided with motor 23 by motor bracket 25, and the output end of described motor 23 is connected with the lower end of described driving main shaft 14, and described driving The upper end of the main shaft 14 extends vertically upwards through the lowermost classification chamber and reaches the uppermost classification chamber. In each layer of the classification chamber and corresponding to the drive main shaft 14, separators are respectively installed. It is a fan structure composed of a first arc-shaped blade 15, a second arc-shaped blade 18 and a third arc-shaped blade 21, the first arc-shaped blade 15, the second arc-shaped blade 18 and the third arc-shaped blade The structural dimensions of the shaped blades 21 are the same, and the outer arc and the inner arc are two sections of Archimedes spirals with different origin points. As shown in Figures 5 and 6, the specific design is as follows:

According to the inner diameter of the largest cylinder and the diameter of the smallest coin to ensure that the arc-shaped blade does not contact the inner wall of the cylinder during the rotation process and the angle between the outer arc section of the arc-shaped blade, the inner wall of the cylinder and the coin is a inferior arc, Take R=90,. This can not only ensure that the arc-shaped blade does not get stuck in the process of rotation, but also prevents the entire coin sorting process from stopping, the coin separation is smoother, and the work efficiency is improved.

Determination of the outer circle and inner circle of the arc-shaped blade: determine the inner hole φ17 according to the size of the shaft. In order to ensure the rigidity requirement, the minimum side width is 7.5. Draw a straight line at the center of the circle about L=17÷2+7.5=16, and deviate from the coordinate line by 15°, then use the center of the circle as the benchmark to evenly distribute, make a circle through the end point of L1 and pass the intersection of φ180 and the coordinate line, and Cut to the straight line passing through the lowest point of φ180 and parallel to the X coordinate line. At this time, it can be determined that the diameter of the large circle of the arc blade is about φ120. Then make a circle passing through the end point of L3 and tangent to φ120. The circle and φ180 The linear distance between the circle intersection point and the left end point of φ180 is about 6 to ensure the rigidity of the tip.

Open the motor 23 in the motor chamber 26 to drive the drive main shaft 14 to run, and the separator in each layer of classification chamber rotates under the drive of the drive main shaft 14. Add the coins that are mixed with different denominations and need to be sorted into the device from the feeding port for sorting. The radial size of the sieve holes on the separating partition is designed according to the diameters of coins of different denominations. For example, the diameter of a 1 yuan coin is about 25mm, the diameter of a 5 jiao coin is about 20.5mm, and the diameter of a 1 jiao coin is about 19mm, so the diameter of the sieve hole on the uppermost separation partition is 22mm to ensure that the 1 yuan coin can be placed on the uppermost layer. The sorting chamber is separated, and the coins of the remaining denominations flow into the next layer of sorting chamber through the sieve holes for further separation. The principle of separating silver coins from the corresponding sorting chamber is as follows: the coins in the sorting chamber are stirred by the rotation of the separator, and the coins separated from this layer are separated from the sorting chamber from the discharge port under the action of the push force, and the coins not separated from this layer The coins flow into the next layer of sorting chamber through the sieve holes to continue separation. The separator adopts the structure of arc blades, which has an outer arc wall and an inner arc wall. Coins rotating along the inner arc wall of the separator will keep spinning, and will not fly out of the sorting chamber due to force, so that the coins can be fully screened out through the separation partition; on the contrary, along the direction of the outer arc wall of the separator The rotating coins can be quickly rotated out of the sorting chamber and collected under the action of the pushing force, thereby completing the collection of coins of the same category.

The coins separated from the discharge port through the rotation of the separator will pass through the out-of-cabin chute 8. Since a secondary screen is provided on the out-of-cabin chute 8, the coins separated from the non-local layer will pass through the process of the cabin chute 8. will be screened out by the secondary sieve and reach the secondary sorting slideway 10, and enter the next layer of sorting room through the secondary sorting slideway 10 to continue to separate, which ensures that the coin sorting is fully and thoroughly, and realizes the final separation of the collected coins. unity.
