Detailed Embodiment

[0029] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the structural diagrams and specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] As Figure 1 and Figure 2 shown, the present utility model provides an embodiment of a full-automatic belt sorting machine. The full-automatic belt sorting machine is divided into two mechanisms: rough screening and precise sorting. The rough screening mechanism first eliminates products with unqualified sizes through the mechanical vibration of the vibrating sorter, and the remaining products with qualified sizes are compared and identified by the precise sorting mechanism to accurately eliminate other defective unqualified products.

[0031] The body 1 is the basic framework of the full-automatic belt sorting machine of the present utility model. Each functional component of the sorting machine is integrated on the body 1, and the body 1 provides stable support for the operation of the equipment. Rollers are provided at the lower part of the body 1, which can facilitate movement. At the same time, a locking device is also provided at the lower part. When working, the position of the body 1 is locked and fixed to avoid the equipment moving due to the vibration generated during the operation of the equipment. Of course, the body 1 can also be completely fixed on the ground.

[0032] The feeding hopper 2 is arranged at the uppermost part of the body 1 and is the inlet of the products to be sorted. The upper hopper opening (feeding port) of the feeding hopper 2 has a sufficient opening degree to facilitate the products to fall into the feeding hopper 2 conveniently; the four side walls of the feeding hopper 2 are connected to each other in an inverted trapezoidal structure to form an inverted trapezoidal hopper body, that is, the side walls adopt an inverted trapezoidal structure with the upper base larger than the lower base. Such an inverted trapezoidal structure makes the area of the feeding hopper 2 gradually shrink from the upper hopper opening to the lower discharge port, so that the products entering the feeding hopper 2 present an inverted trapezoidal shape when piled up at the bottom of the discharge port. The volume of the products piled up in the upper part is larger than that of the products in the lower part, so the weight of the upper products generates pressure on the lower products, and then promotes the lower products to leave the discharge port at the lower part of the feeding hopper 2 orderly. In this embodiment, preferably, the side wall of the feeding hopper 2 close to the vibration sorting screen 4 is arranged vertically at a 90-degree angle to the horizontal plane, and the two adjacent side wall plates are right trapezoids, and the opposite side wall plate is an isosceles trapezoid. The three side walls are all inclined at an angle less than 90 degrees to the horizontal plane and shrink from top to bottom. After the four side walls are connected, they form a funnel body in the shape of an inverted right trapezoid. The inclination angles of the three inclined side walls can be selected between 30 degrees and 60 degrees. Such inclination angles are helpful for discharging materials and controlling the discharging speed, and can make the gravity component of the products in the feeding hopper overcome the friction force between the products and the side walls of the hopper, so that the products can flow out of the hopper smoothly. If the inclination angle of the hopper is too small, the gravity component of the products is not enough to overcome the friction force, resulting in the products accumulating at the bottom of the hopper and unable to discharge materials smoothly. If the inclination angle of the side wall is too large, the sliding speed of the products is too fast, resulting in too fast discharging and difficult to control. The specific inclination angle needs to be determined by comprehensively considering the material of the products, the viscosity of the products and the friction force, etc. The three inclined side walls are also helpful for guiding the flow direction of the products.

[0033] The lower opening of the feeding hopper 2 is rectangular or square, and a vibrating sorting screen vibrator 3, such as an electromagnetic vibrator or an air vibrator, is provided below the opening. The products to be sorted move towards the vibrating sorting screen 4 under the vibration of the vibrating sorting screen vibrator 3. The sorting gap of the vibrating sorting screen 4 is smaller than the normal product size. When the products pass through the vibrating sorting screen 4, the unqualified products that are much smaller than the normal product size fall through the sorting gap and into the waste hopper 5. In this embodiment, the vibrating sorting screen 4 is preferably in the form of a grille, and the gap between the grilles is smaller than the normal product size. The vibrating sorting screen can also be in other shapes such as similar meshes or grids, as long as the sorting gap is smaller than the normal product size, the purpose of vibrating sorting can be achieved. In the embodiment of the present utility model, the rough selection and screening mechanism uses simple mechanical vibration to first remove the products with unqualified sizes, reducing the workload of subsequent precise sorting. The design of the shape and position of the feeding hopper, with the help of the self-gravity of the products, enables the products to enter the subsequent links orderly, and the manual or automatic feeding link does not require refined operation, and the operation is simple.

[0034] The other products after rough selection and screening continue to move forward under the vibration of the vibrating sorting screen vibrator 3 and reach the guide hopper 6. One end of the guide hopper 6 is connected to the vibrating sorting screen 4, and the other end is connected to the guide trough 8 located below. Since there is a certain height difference between the vibrating sorting screen 4 and the guide trough 8 in the vertical direction, the guide hopper 6 has an angle inclined from top to bottom from the vibrating sorting screen 4 to the guide trough 8. Due to the height difference, the products slide automatically from above the guide hopper 6 to below the guide hopper 6 under the action of gravity, and then enter the horizontally arranged guide trough 8. In order to enable the products to enter the guide trough 8 orderly, a guiding block is provided below the guide hopper 6, so that the products sliding down from the guide hopper 6 enter the guide trough 8 with the help of the separation and guiding of the guiding block; another method of orderly guiding is to provide a guiding track in the guide hopper 6, and the number and position of the guiding track correspond to those of the guide trough 8. The products in the vibrating sorting screen 4 move above the guide hopper 6 under the vibration, enter the guiding track of the guide hopper 6 in sequence, and slide down along the guiding track into the guide trough 8 connected to the lower part of the guide hopper 6. The guide hopper and the guide trough together form a guiding device, which guides the products from the high vibrating sorting screen to the horizontal guide trough and further orderly diverts and runs to the belt conveyor device.

[0035] Such as Figure 3As shown in the figure, the present utility model provides an embodiment of a belt conveying device of a full-automatic belt sorting machine. The material guiding groove 8 is horizontally arranged above the circular polyurethane conveyor belt 9, and its cross-section is an inverted trapezoidal structure with a narrow opening at the lower part. This structural design of the material guiding groove 8 enables the products entering the material guiding groove 8 to directly fall onto the circular polyurethane conveyor belt 9 below the material guiding groove 8. Due to the depth design of the inverted trapezoidal groove body, the products are relatively stable during the movement along with the conveyor belt. The number of the material guiding grooves 8 is at least more than one. In order to improve the efficiency, multiple parallel material guiding grooves 8 can be arranged. The lower opening of the material guiding groove 8 corresponds to the belt conveying device formed by the circular polyurethane conveyor belt 9: the circular polyurethane conveyor belt 9 is supported by a conveyor driving roller 7 and a conveyor driven roller 10 to form a conveyor belt group. The conveyor reduction motor 17 is connected to the central axis of the conveyor driving roller 7, driving the conveyor driving roller 7 to rotate, and then driving the conveyor driven roller 10 to rotate, thereby driving the circular polyurethane conveyor belt 9 to move linearly, thus constituting the belt conveying device of the embodiment of the present utility model. The circular polyurethane conveyor belt 9 includes at least one group of conveyor belt groups composed of two single circular polyurethane conveyor belts. Each conveyor belt group includes a left circular polyurethane conveyor belt 18 and a right circular polyurethane conveyor belt 20. The two conveyor belts are close to each other to form an object supporting trough body, holding the products to be sorted 19 and driving them to be conveyed at a high speed. The number and position of the conveyor belt groups correspond to the number and position of the material guiding grooves 8, enabling the products to be sorted to smoothly move from the high-level feeding hopper 6 to the horizontally arranged material guiding groove 8 and stay in the conveying group trough body of the circular polyurethane conveyor belt 9. With the design of the feeding hopper and the material guiding groove, the products moving in a flat and spreading manner on the vibrating sorting screen are further orderly introduced into the conveyor belt, becoming the main body running in a single sequence, preparing for the subsequent photographing process of the industrial camera. On the other hand, the reason for choosing the polyurethane conveyor belt is that the polyurethane conveyor belt has excellent wear resistance and elasticity, can withstand large tensile and impact forces, and is suitable for long-term and high-frequency use; secondly, it is resistant to grease and easy to clean. The surface of the polyurethane conveyor belt is flat and smooth, not easy to accumulate impurities and bacteria, and can be directly washed with water or cleaned by a cleaning machine, which is very important for pharmaceutical production.

[0036] As described above, the products to be sorted 19 are guided by the material guiding groove 8 to the circular polyurethane conveyor belt 9 and stay in the conveyor belt group trough body. Along with the horizontal movement of the circular polyurethane conveyor belt 9, they are conveyed to the end of the conveyor belt and are thrown straight forward under the action of inertia force and inertial speed, entering the photographing unit 11 and becoming the products being photographed 23.

[0037] As Figure 4As shown in the figure, the present utility model provides an embodiment of a photographing unit of a full-automatic belt sorting machine. The photographing unit 11 is composed of a photographing unit box body 21, an industrial camera 22, and a photographing lamp 24. When the product 23 to be photographed enters the photographing unit 11, the industrial camera 22 distributed on the box body of the photographing unit 21 starts to photograph it omni-directionally, and transmits the taken photos to the computer processing system for analysis and comparison using a pre-generated model. The computer processing system calibrates the unqualified products with defects such as out-of-tolerance external dimensions, black dots on the surface, and air bubbles inside. In this embodiment, the photographing unit box body 21 is preferably cylindrical. Three industrial cameras 22 are equidistantly distributed on the circumference of the photographing unit box body 21, and the central angles formed by the connecting lines with the center of the photographing unit 11 are all 120 degrees. Similarly, three photographing lamps 24 are also equidistantly distributed on the circumference of the photographing unit box body 21, and the central angles formed by the connecting lines with the center of the photographing unit 11 are all 120 degrees. The photographing lamps are evenly distributed at intervals from the industrial cameras on the circumference. By using the setting method of evenly distributing three industrial cameras and three photographing lamps on the circumference of the photographing unit box body 21, it can ensure that the photographing unit obtains omnidirectional illumination and 360-degree photographing. The omnidirectional illumination creates perfect photographing light, and the product details are perfectly presented. The industrial cameras photograph the product from three directions at multiple angles, making the photographing detection comprehensive without dead angles, and can ensure clear photos of the product, so that the subsequent comparison and analysis procedures can be smoothly implemented.

[0038] Of course, the outer shape of the photographing unit box body 21 can also be a square box body or a box body with other regular shapes. In order to ensure clear product photos, it is easier to meet the requirements by using the setting method of evenly distributing three industrial cameras and three photographing lamps with the running straight line of the product 23 to be photographed in the photographing unit box body 21 as the center point.

[0039] As Figure 1 shown in the figure, after the computer processing system calibrates the unqualified products, it transmits the calibration information and control signals of the positions of the unqualified products to the blowing valve 12. When the unqualified product reaches the rejection position, the blowing valve 12 is activated to blow the unqualified product into the waste hopper 13 to become the rejected unqualified product 14, while the qualified product 16 continues to move forward and falls into the qualified product hopper 15 to complete the finished product recovery.

[0040] The technical solution of the present utility model uses a vibration sorting device for rough screening of products, screening out products with unqualified sizes, thereby reducing the workload of subsequent photographing and sorting. In the subsequent fine sorting stage, through a phased material guiding link, the products after rough screening are arranged in an orderly manner and sent into an industrial camera for photographing one by one. Then, a model trained through machine learning is used to conduct a comparative analysis of the products, screening out other unqualified products and recycling qualified products. The present utility model combines simple and effective mechanical design and artificial intelligence technology, realizing the efficient operation of product inspection, reducing the labor intensity of workers, reducing product pollution, and being conducive to the automation of product production.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
