When sorting coins, the workload of sorting banknotes and coins of different denominations is relatively large, and manual screening is prone to errors.

In response to the above problems, relevant engineering and technical personnel have developed a series of devices related to coin classification. Among them, it is roughly divided into a separation device for banknotes and coins and a sorting device for coins. Among them, most of the banknote and coin separation devices realize the separation of single banknotes and coins, and the device principles are generally complicated, and it is difficult to apply on a large scale in practical applications. The commonly used methods include lever separation, wind blowing method, and water float method. Wait. The coin sorting device adopts the following two methods: the first is the centrifugal separation of coins, which is separated by throwing them to different collection trajectories according to the centrifugal force of different masses of different coins; the other method is Different diameters are used for classification, but most of the existing devices for sorting coins by different diameters are classified through holes of different diameters. The classification accuracy is not high, the efficiency is low, and there is a situation that small diameter holes are blocked by large diameter coins. In view of the above problems, it is very important to design a paper coin sorting and coin sorting device with high separation efficiency and good separation accuracy.

The operation of the stepper motor 5 drives the separation box to rotate, and paper coins are placed in the separation box. During the rotation of the separation box, the coins mixed in the banknotes fall through the strip-shaped gaps of the coin sieve plate 14 on the separation box due to gravity. And be sorted out, and make to sort out coin from banknote and coin, fall into the coin sorting mechanism below. In specific implementation, the rotation of the separation box driven by the stepping motor 5 should be slow.

As shown in Figure 5, coin sorting mechanism 7 comprises slide rail frame 12, slide rail 8, baffle plate 9, coin position correction structure 20, side plate 22, slide rail baffle plate 23 and coin track plate 24; It is a square frame structure, and a coin position correction structure 20 is arranged in the middle of the square frame structure, and the coins sorted out by the paper coin sorting mechanism 13 directly fall on the coin position correction structure 20, as shown in Figure 6, the coin position correction structure 20 is It is formed by a plurality of triangular prisms arranged in parallel at intervals, and there is a gap between adjacent triangular prisms, the gap is greater than the thickness of the coin and less than twice the thickness of the coin; so that when the coin falls into the coin position correction structure 20, it will enter the adjacent The gap in the middle of the triangular prism enters in the slide rail 8 below in an upright state.

As shown in Figures 5 and 7, the lower part of the slide rail frame 12 is a 1/4 arc-shaped track frame structure that is arranged obliquely downward. The track frame structure is connected to the lower end opening of one side edge of the square frame structure. A plurality of slide rail baffles 23 are arranged at intervals between the side plates 22 on both sides of the lower part of the 12, and the slide rail baffles 23 divide the space of the track frame structure at the lower part of the slide rail frame 12 into a plurality of 1/4 arc-shaped slide rails.

The same coin track plate 24 is arranged at the bottom of the square frame structure on the top of the slide rail frame 12 and the track frame structure of the lower part, and the coin track plate 24 is used as a plate for receiving and moving coins.

After the slide rail accepts the coins sorted out by the paper coin sorting mechanism, the coin will roll along the predetermined trajectory, and finally fly out from the end along the parabolic trajectory. The side of the slide rail 8 lower end is provided with a baffle 9, according to the The distance between 9 and the lower end of the slide rail 8 and the position setting make different coins slide out of the slide rail 8 without colliding with the baffle 9 and collide with the baffle 9 at different positions of the coins, so that different coins have different trajectories. Finally, it falls into different positions of the coin collecting mechanism 10 to realize sorting.

In specific implementation, the height of a single slide rail 8 is about 80-100 mm, the distance between the centers of two adjacent slide rails 8 is 30 mm, which is slightly larger than the maximum diameter of a coin of 25 mm, and there is a gap of 3 mm between adjacent slide rails 8 . The circle radius 135mm of the 1/4 circular arc of slide rail 8 is suitable for sliding down of three kinds of coins of one yuan, five jiao and one jiao.

The working principle of the present invention is mainly as follows.

After the mixed currency mixed with banknotes and coins passes through the paper coin sorting mechanism 13, the remaining banknotes remain in the separation box, and the coins fall into the coin sorting mechanism 7 positioned directly below the paper coin sorting mechanism through the coin sieve plate 14. In the coin sorting mechanism, the coin is adjusted in the slide rail 8 after passing the position correction mechanism 20, and enters the semicircular arc-shaped exit track through the coin track 24 and flies out from the end of the track. After the diameter baffle plate 9 hits, different specifications Coins have produced different parabolic trajectories, wherein the one-yuan coin with a diameter of 25mm has the most obvious change in trajectory, and falls into the partition of the collection box 10 closest to the coin sorting mechanism 7, and the pentagon coin with a diameter of 20.5mm changes slightly. In the partition in the middle of the collection box 10, the dime coin with a diameter of 19mm has no track change and falls into the farthest partition of the collection box 10, thereby realizing the classified collection of each different currency.

Figure 2 shows an enlarged view of the paper coin sorting mechanism. When the overall mechanism is not working, the stepper motor 5 will rotate, driving the spline shaft to rotate, and the spline shaft will drive the sorting mechanism to rotate so that the top door plate 19 of the separation box is in an upward state, and the side door shaft side is fixedly connected with the slider 18, The sliding block 18 is lined in the sliding groove 17 and can realize low-friction sliding. When device starts working, steering gear 2 drives four-bar linkage 3 and rotates and the separation box top door panel 19 is opened, and after putting into paper coin mixed currency, steering gear 2 drives four-bar linkage 3 to rotate and closes separation box side 19. Then the stepper motor 5 starts to rotate, and the paper coin mixed currency in the paper coin sorting mechanism 13 will constantly rotate, and the coin wherein will pass through the coin sieve plate 14 from the rectangular hole of 5 * 30mm that has on the sieve plate. Then stay in the paper coin sorting mechanism 13. After the coins in the paper coin sorting mechanism 13 are completely separated, the first step of paper coin sorting is realized.

After the coins separated from the paper coin sorting mechanism fall into the coin sorting mechanism 7, what pass through at first is a coin position correction structure 20 in the shape of a triangular prism. The distance between two adjacent triangular prisms is 30mm, which is 25mm larger than the diameter of the largest coin. When the coin falls into the correction structure, it will enter the middle part of the adjacent triangular prism. There is a gap of 3mm between the two triangular prisms, and the maximum allowable thickness is 1.85 The passage of the one-dollar coin of mm. After the coin position correction structure 20 adjusts the coin position, each coin can be in a vertical state and enter the slide rail 8 . After the coin enters the slide rail 8, it falls into the coin track 24 assembled on the lower end of the slide rail 8. The movement of the coin track 24 will finally fall into the quarter circle area of the lower end of the track, and fly out freely through the end. The end is equipped with a baffle plate 9 outside, and the lowest position of the baffle plate 9 is 19.5mm away from the lowest point of the arc at the end of the coin track 24.

Coin is to adopt Renminbi coin, is divided into one yuan coin, five jiao coin and one jiao coin; Described coin collecting mechanism 10 mainly is made up of three storage areas, is divided into one yuan coin storage area, five jiao coin along distance coin sorting mechanism 7 from near to far. Storage area and dime storage area.

When the coin that flies out is the one-yuan coin of diameter 25mm, the parabolic locus of one-yuan coin can be subjected to bigger change, thereby falls in the partition (one-yuan coin storage area) in the collection box 10 nearest from coin sorting mechanism 7.

When the flying coin is a pentagon coin with a diameter of 20.5mm, the parabolic trajectory of the pentagon coin will be slightly changed, so as to fall into the middle partition (penta coin storage area) of the collection box 10 .

When the coin that flies out is the dime of diameter 19, dime can not touch with baffle plate 9, therefore can not have the change of parabolic trajectory, thereby falls into the collection box 10 farthest away from coin sorting mechanism 7 In the partition (dime storage area), the classification collection of three different coins is finally realized.

It can be seen that the present invention makes use of the feature that the coin itself is smaller and lighter than paper money to separate the coins from the screen on the side of the box body, and uses the different diameters of coins of different denominations so that the trajectory changes after passing through the same baffle are different to carry out coin classification. Paper coin separation, coin classification, and classification accuracy and efficiency are relatively high.
