Detailed ways

The following detailed description is illustrative rather than restrictive, and should not be used to limit the scope of the present invention.

As shown in Figure 1, the present invention includes: a coin and banknote separation part 2, an inclined sorting tray part 3, a coin transport and collection part 4, and a frame 31. The coin and banknote separation part 2, the inclined sorting plate part 3, and the coin transport and collection part 4 are all fixedly connected to the frame 31 through bolts.

As shown in Figure 2, the coin and banknote separation part 2 includes: a coin inlet funnel 5, a coin slide 6, a fan 7, a banknote channel 8, a coin separation net 9, and a coin channel 10. The coin entrance funnel 5, the banknote channel 8, the coin separation net 9, and the coin channel 10 are all connected to the coin slide 6 through bolts; the banknote exit end side of the coin slide 6 is processed with multiple air outlets, and its bottom surface (slide) The angle with the horizontal plane is 40°; the fan 7 is installed on the frame 31, and the wind blown by it flows through the mesh of the coin separation net 9 to the banknote outlet end of the coin slide 6, blowing the banknotes entering from the coin entrance funnel 5 Entering the banknote channel 8, the coins leak out from the coin separation net 9 and enter the coin channel 10; the mesh size of the coin separation net 9 is a square hole with a side length of 26 mm.

The mixed coins and banknotes enter from the coin entrance funnel 5 and slide down the bottom of the coin slide 6 due to gravity. The coins slide to the coin separation mesh 9 and then fall from the mesh. The banknotes are blown into the banknote channel 8 by the fan 7. This enables the separation of coins and banknotes. Coins that fall into the coin channel 10 through the mesh of the coin separation net 9 slide to three inclined sorting plates through three connecting pipes for sorting (the number of inclined sorting plates depends on the coin sorting volume, which can be It can be one, or it can be more than two).

As shown in Figures 1 and 3, the tilted sorting plate part includes: display screen 1, turntable cover 11, turntable base 12, base 13, centrifugal turntable 14, coin sorting channel 15, infrared counting sensor 16, speed regulation Motor 17. Among them, the bottom of the base 13 is connected to the lower box 23 through bolts, and the left and right slopes of the base 13 form an acute angle of 45° with the horizontal plane; the speed-regulating motor 17 is connected to the right slope of the base 13 through bolts, and the speed-regulating motor 17 The axis line forms an angle of 45° with the horizontal plane, and a bearing is arranged between the shaft of the speed regulating motor 17 and the center hole of the turntable base 12; the turntable base 12 is connected to the left slope of the base 13 through bolts, and the inclination angle of the turntable base 12 It's also 45°.

As shown in Figure 4, the coin slide of the turntable base 12 is provided with four rectangular holes. The rectangular holes 32, 33, 34, and 35 correspond to currency values of 1 yuan, 0.1 yuan (old version), 0.5 yuan, and 0.1 yuan ( New version) of the coin outlet, the long sides of the rectangular holes are 50mm, the short sides are 24mm, 22mm, 20mm and 18mm respectively. The distance between the lower edge of the rectangular hole and the lower edge of the coin slide is 2mm, and the interval between the rectangular holes is 5mm. A coin guide arc 36 is processed at the upper end of the coin slide opening when the coins are thrown to the coin slide. When the coins are thrown to the coin slide, they will roll along the coin slide due to centrifugal force. The function of the coin guide arc 36 is to guide the coins along the coin slide. The lower edge of the track rolls. Therefore, coins of different denominations can fall from corresponding rectangular holes according to the different diameters of the coins during the sliding process. The cross-section of the coin slide on the turntable base is a rectangular cavity. The long side of the rectangular cavity is 30mm and the short side is 2.6mm.

As shown in Figure 5, the centrifugal turntable 14 is evenly processed with 13 U-shaped coin slots 38 of the same size (slot width is 26mm, slot length is 26mm) with radial openings facing outward.

The shaft connection of the speed motor 17; the thickness of the centrifugal turntable 14 is 1.5mm, the radial gap between the outer circle of the centrifugal turntable 14 and the turntable base 12 is 3mm, and the height of the upper surface of the centrifugal turntable 14 from the upper surface of the turntable base is 1.8mm, thereby ensuring that each coin One rotation of the hole separates only one coin.

As shown in Figure 6, the upper end of the turntable cover 11 is processed with a coin inlet 37. The coin inlet 37 is connected to the outlet of the coin channel 10 in the coin and banknote separation part, and a connecting pipe can be used to communicate in the middle. The turntable cover 11 is connected to the turntable base 12 through bolts. A closed cylindrical cavity is formed between the turntable base 12 and the turntable cover 11. The height of the cylindrical cavity is 2.8mm. The centrifugal turntable 14 is arranged on the axis of the cylindrical cavity. superior.

The structure of the coin sorting channel 15 includes four infrared counting sensors 16 and four coin channels (corresponding to coins of four denominations respectively). Four infrared counting sensors 16 are respectively arranged above the four coin channels; the coin sorting channel 15 is connected to the turntable base 12 through bolts.

The coins slide onto the centrifugal turntable 14 through the coin inlet 37. The speed-regulating motor 17 drives the centrifugal turntable 14 to rotate. The U-shaped coin slot 38 on the centrifugal turntable 14 separates the coins one by one and rotates them, causing them to rotate one by one through centrifugal force. Slide into the coin slide. There are four rectangular holes (coin exits) 32, 33, 34, 35 on the coin slide. Coins of different denominations will pass through the rectangular holes corresponding to their corresponding heights during the rolling process due to different diameters. Fall to the corresponding four coin channels in the coin sorting channel 15. Four infrared counting sensors 16 are installed above the four coin channels. The infrared counting sensors 16 count the coins of four different denominations that pass through, and feed back the counting status to On the LCD screen 1, the process of separating, sorting and counting coins is completed.

Figure 7 is a schematic diagram of the coin transport and collection section 4. This part includes: driven pulley 18, pulley motor 19, motor base 20, driving gear 21, driven gear 22, lower box 23, partition 24, baffle 25, driving pulley 26, bearing seat 27, Conveyor belt 28, banknote storage box 29, coin storage box 30; the motor base 20 is connected to the lower box 23 through bolts, the pulley motor 19 is connected to the motor base 20 through bolts, the driving gear 21 meshes with the driven gear 22, and the driving gear 21 is installed on the pulley motor 19 shaft, and the driven gear 22 is installed on the driving pulley 26 shaft; the two pulley shafts are respectively equipped with the driven pulley 18 and the driving pulley 26; four pairs of pulleys are respectively connected with the four conveyor belts. 28 cooperate to form a belt transmission mechanism; the bearing seat 27 is installed on the lower box 23 through bolts, and the two pulley shafts are arranged on the bearing seat 27. The lower box 23 is fixed on the frame 31.

Four coin sliding inlets are provided on the lower box 23 below the output ends of the four conveyor belts 28. Baffles 25 are fixed at the four coin sliding inlets. The four coin sliding inlets are connected with the four coins in the lower box 23.
