[0015] Compared with the prior art, the present invention provides a sorting and sorting device and a sorting and sorting process for Chinese medicinal materials, which has the following beneficial effects: 1. This diversion and sorting equipment, through the arrangement of diversion plates, conveyor belts, and sorting mechanisms, diverts the medicinal materials to be sorted onto multiple conveyor belts, thereby reducing the sorting pressure on the sorting mechanism. As the conveyor belts transport the medicinal materials to be sorted one by one to the inspection table, the sliding plate drives the pusher plate to push the medicinal materials on the conveyor belt onto the inspection table. The inspection table drives the medicinal materials to tumble through an electric roller, allowing an industrial camera to perform a comprehensive inspection of the medicinal materials. This prevents blind spots in the inspection of the medicinal materials and avoids inaccurate inspection results, thereby ensuring the uniform quality of the sorted medicinal materials and meeting the modern industry's demand for precise and standardized sorting.

[0016] 2. This sorting and picking equipment, through the cooperation of the transmission component and the baffle, allows the sliding plate to open the closed baffle via the transmission component when it moves towards the baffle, thus releasing the herbs blocked by the baffle and allowing them to continue moving towards the inspection table. When the sliding plate drives the push plate to push the herbs onto the inspection table, the sliding plate closes the open baffle via the transmission component, thus blocking the next herb and providing sufficient time for the herbs to be inspected on the inspection table, making the inspection results more accurate and improving the picking accuracy of the picking component.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-11A sorting and picking device includes a mounting frame 1, on which a sorting plate 12 and multiple conveyor belts 11 are sequentially mounted. The sorting plate 12 has multiple channels, each corresponding to a conveyor belt 11. The mounting frame 1 is equipped with a picking mechanism 2 and a transmission assembly 3. The picking mechanism 2 includes baffles 21, an inspection table 22, a sliding plate 23, and a pusher plate 26. Baffles 21 are installed on both sides of the conveyor belts 11, initially in a closed state. The inspection table 22 is mounted on the conveyor belts 11 and has... An electric roller 222 is provided, and an industrial camera 28 for inspecting medicinal materials is installed above the inspection table 22. A sliding plate 23 is installed above the inspection table 22 and can slide back and forth horizontally along the conveyor belt 11. A push plate 26 is connected below the sliding plate 23 and can move vertically up and down. When picking medicinal materials, the push plate 26 moves onto the conveyor belt 11. After the push plate 26 moves, the sliding plate 23 can drive the push plate 26 to move horizontally, thereby pushing the medicinal materials on the conveyor belt 11 onto the inspection table 22. The transmission assembly 3 includes a movable plate 31, which is mounted above the baffle 21 and is elastically connected to the conveyor belt 11. When the sliding plate 23 moves horizontally toward the diverter plate 12, it can drive the movable plate 31 to move in the same direction, forcing the baffle 21 to open.

[0021] In operation, the herbs to be selected first enter the diversion plate 12. The diversion plate 12 divides the batch of herbs into two parts through two channels. The herbs then enter two conveyor belts 11, which, driven by motors, transport the herbs towards the baffles 21. At this time, the two baffles 21 are closed. The sliding plate 23 is located on the side of the inspection table 22 away from the baffles 21. The push plate 26 rises and then hangs above the inspection table 22 without contacting it. When the first herb is transported by the conveyor belt 11 to contact the closed baffles 21, the sliding plate 23 drives the push plate 26 to move towards the baffles 21. During the movement of the sliding plate 23, the sliding plate 23 drives the moving plate 31 to move synchronously. As the moving plate 31 moves, the closed baffle 21 gradually opens. When the sliding plate 23 moves to the side of the inspection table 22 near the baffle 21, so that the push plate 26 is located between the inspection table 22 and the baffle 21, the sliding plate 23 stops moving. At this time, when the baffle 21 is fully open, the medicinal materials are released. The conveyor belt 11 carries the medicinal materials from under the push plate 26 and continues to move towards the inspection table 22. At the same time, the push plate 26, which is suspended under the sliding plate 23, begins to move downward until it touches the conveyor belt 11. Then the sliding plate 23 drives the... The pusher plate 26 begins to move in the opposite direction away from the baffle 21, pushing the medicinal materials onto the inspection table 22 for inspection. Simultaneously, as the sliding plate 23 moves in the opposite direction, the opened baffle 21 closes again, preventing the next medicinal material from being inspected. This allows sufficient time for inspection of the medicinal materials on the inspection table 22. When the pusher plate 26 pushes the medicinal materials onto the inspection table 22, they first fall onto the electric roller 222. At this point, the pusher plate 26 stops moving, and the electric roller 222 begins to rotate under electric power, causing the medicinal materials on it to roll. The industrial camera 28 then performs a comprehensive inspection of the medicinal materials to check their quality. After the medicinal materials on the inspection table 22 have been inspected, the sliding plate 23 continues to move away from the baffle 21, causing the push plate 26 to push the medicinal materials to continue moving, eventually pushing the medicinal materials off the inspection table 22, so that the inspected medicinal materials return to the conveyor belt 11 and continue to be transported by the conveyor belt 11. Among them, the qualified medicinal materials will continue to remain on the conveyor belt 11 until they are transported to the next process, while the unqualified medicinal materials will be rejected, thus completing the medicinal material picking work. After pushing the medicinal materials off the inspection table 22, the sliding plate 23 moves back towards the baffle 21 and retracts the push plate 26 to start inspecting the second medicinal material.

[0022] Furthermore, the conveyor belt 11 is fixedly mounted on the mounting frame 1, and a cover 13 is fixedly mounted on the conveyor belt 11. Slide rails 131 are fixedly mounted on both sides of the top of the cover 13. A drive groove 132 is formed on the top of the cover 13, located between the slide rails 131. A motor groove 133 is formed on the top of the cover 13, located at the end of the drive groove 132 away from the diverter plate 12. Two slots 134 are formed on the cover 13, located on both sides of the drive groove 132 and between the two slide rails 131. Two limiting plates 135 are fixedly mounted on the top inside the cover 13, located between the drive groove 13 and the two slide rails 131. On both sides of 2, the top inside the cover 13 is rotatably connected to a drive gear 33 and a driven gear 34. The drive gear 33 and the driven gear 34 are located at the end of the cover 13 near the flow divider 12. The drive gear 33 and the driven gear 34 mesh. Both sides of the conveyor belt 11 are fixedly connected to slide rods 136. The slide rods 136 are located above the conveyor belt 11. A return spring 137 is sleeved on the slide rod 136. One end of the return spring 137 is fixedly connected to the end of the slide rod 136 near the flow divider 12. A discharge port 138 is opened on the conveyor belt 11. The discharge port 138 is located on the side of the inspection table 22 away from the baffle 21. The discharge port 138 penetrates the cover 13.

[0023] Furthermore, the two sides of the bottom of the sliding plate 23 are slidably mounted on two slide rails 131 via sliders. A connecting block 231 is fixedly connected to the bottom of the sliding plate 23. The connecting block 231 is located in the drive groove 132. A mounting plate 24 is fixedly connected to the bottom of the connecting block 231. The mounting plate 24 is located at the top inside the cover 13. The mounting plate 24 has two grooves, which correspond to two limiting plates 135 respectively. The two limiting plates 135 are located in the two grooves respectively. One of the grooves is fixedly installed. There is a fixed rod 241, which is slidably connected to the limiting plate 135 in the groove. A drive rack 242 is fixedly connected to the fixed rod 241, and the drive rack 242 meshes with the drive gear 33. Drive cylinders 25 are fixedly installed on both sides of the sliding plate 23. The output shaft of the drive cylinder 25 slides through the sliding plate 23, and a pull rod 251 is fixedly connected to the output end of each drive cylinder 25. The pull rod 251 slides through the slot 134 through the mounting plate 24 and extends to the top of the inspection table 22.

[0024] When the sliding plate 23 moves, it drives the mounting plate 24 to move synchronously via the connecting block 231. When the sliding plate 23 drives the mounting plate 24 to move towards the baffle 21, the fixing rod 241 drives the drive rack 242 to slide in the same direction on the limiting plate 135, causing the drive rack 242 to move closer to the drive gear 33. As the fixing rod 241 continues to move, the drive rack 242 eventually meshes with the drive gear 33, thereby driving the drive gear 33 to rotate in the opposite direction. The rotating drive gear 33 drives the driven gear 34, which meshes with it, to rotate in the forward direction. When the sliding plate 23 drives the mounting plate 24 to move away from the baffle 21, the sliding plate 23 drives the mounting plate 24 to move in the same direction. When the slide plate 23 moves away from the baffle 21, the fixed rod 241 drives the drive rack 242 to move in the opposite direction. At this time, the drive gear 33 rotates in the forward direction, thereby driving the driven gear 34 meshing with it to rotate in the opposite direction. As the slide plate 23 continues to move away, when the slide plate 23 drives the push plate 26 to move onto the inspection table 22, the drive rack 242 and the drive gear 33 separate, ending the meshing. When it is necessary to retract the push plate 26, the drive cylinder 25 pulls the pull rod 251 upward by retracting its output shaft. When it is necessary to lower the push plate 26, the drive cylinder 25 pushes the pull rod 251 downward by extending its output shaft.

[0025] Furthermore, sleeves 261 are fixedly connected to both sides of the upper end of the push plate 26, the lower end of the pull rod 251 is slidably connected to the sleeve 261, and a compression spring 262 is sleeved on the outer side of the sleeve 261. The two ends of the compression spring 262 are fixedly connected to the upper side of the push plate 26 and the lower side of the mounting plate 24, respectively.

[0026] When the push plate 26 is lowered, as its lower end abuts against the conveyor belt 11, the lower end of the pull rod 251 moves towards the lower end of the sleeve 261, thereby compressing the pressure spring 262 to store force, allowing the push plate 26 to press tightly against the conveyor belt 11. As the sliding plate 23 moves the push plate 26 from the conveyor belt 11 to the inspection table 22, the push plate 26 moves along the slope of the inspection table 22, causing the lower end of the pull rod 251 to move further towards the lower end of the sleeve 261 and further compress the pressure spring 262. When the push plate 26 is retracted, the compressed pressure spring 262 recovers its deformation, and the lower end of the pull rod 251 slides to the upper end of the sleeve 261. When the push plate 26 is suspended on the inspection table 22, the pressure spring 262 does not deform and is in a relaxed state.

[0027] Furthermore, the picking mechanism 2 also includes a servo motor 27, which is fixedly installed in the motor slot 133. A drive screw 271 is coaxially fixedly connected to the output shaft of the servo motor 27. The end of the drive screw 271 away from the servo motor 27 is rotatably connected to the side wall of the drive slot 132. A connecting block 231 is fitted onto the drive screw 271 by a threaded fitting. An industrial camera 28 is fixedly connected to the top of the cover 13 and is tilted downwards to inspect the medicinal materials on the inspection table 22.

[0028] When the sliding plate 23 needs to move towards the baffle 21, the servo motor 27 drives the drive screw 271 to rotate in the opposite direction. The connecting block 231, with the engagement of the threads, drives the sliding plate 23 to move towards the baffle 21. When the sliding plate 23 needs to move away from the baffle 21, the servo motor 27 drives the drive screw 271 to rotate in the forward direction. The connecting block 231, with the engagement of the threads, drives the sliding plate 23 away from the baffle 21. When the medicinal material rotates under the drive of the electric roller 222, the industrial camera 28 performs a comprehensive inspection of the surface of the medicinal material to check whether there are any defects on the surface. When the surface of the medicinal material is defective, when the push plate 26 pushes the medicinal material off the inspection table 22, the defective medicinal material will be removed from the conveyor belt 11 by the picking mechanism 2, thereby picking out the medicinal material with good quality.

[0029] Furthermore, an installation groove 221 is provided on the side of the inspection table 22 near the baffle 21. An electric roller 222 is rotatably installed on one side of the installation groove 221, and a rotating roller 223 is rotatably installed on the other side of the installation groove 221. The electric roller 222 rotates to turn the medicinal materials over. A checkweigher 224 is fixedly installed on the other side of the inspection table 22. The checkweigher 224 is used to weigh the medicinal materials.

[0030] When the pusher plate 26 pushes the medicinal material onto the inspection table 22, the material first falls into the mounting groove 221, positioned between the electric roller 222 and the rotating roller 223. The electric roller 222 rotates under electric power, causing the material to rotate between them, allowing the industrial camera 28 to fully inspect it. After the industrial camera 28 completes its inspection, the sliding plate 23 again moves the pusher plate 26 away from the baffle 21, pushing the material out of the mounting groove 221. The pusher plate 26 then pushes the material onto the checkweigher 22. 4. The weight of the medicinal material is measured by the checkweigher 224 to check whether the weight of the medicinal material is qualified. After the medicinal material is weighed, the sliding plate 23 drives the push plate 26 to push the medicinal material off the inspection table 22, thereby ensuring the accuracy of the selection of medicinal materials and ensuring the quality of the selected medicinal materials. The weighing platform of the checkweigher 224 is lower than the upper side of the inspection table 22. The push plate 26, which is against the inspection table 22, does not come into contact with the checkweigher when it passes the checkweigher 224, ensuring the accuracy of the weighing data of the checkweigher 224. Medicinal materials with unqualified weight will be rejected from the conveyor belt 11 by the picking mechanism 2.

[0031] Furthermore, one end of the baffle 21 is rotatably connected to the side of the conveyor belt 11. The baffle 21 is located at one end of the inspection table 22 near the diverter plate 12. A sliding seat 211 is slidably installed on the upper side of the baffle 21. The sliding seat 211 can slide horizontally along the upper side of the baffle 21. A roller 212 is rotatably connected to the sliding seat 211.

[0032] Furthermore, the movable plate 31 is slidably mounted above the conveyor belt 11. An arc-shaped groove 311 is provided on the movable plate 31, and the roller 212 is slidably mounted in the arc-shaped groove 311. Sliding blocks 312 are fixedly connected to both sides of the movable plate 31 near the diverter plate 12. The sliding blocks 312 are slidably mounted on the slide rod 136 and abut against the other end of the return spring 137. A support plate 32 is fixedly connected to the upper side of the movable plate 31. A connecting rod 321 is fixedly connected to the top of the support plate 32. The connecting rod 321 is slidably connected to another limiting plate 135, and a transmission rack 322 is fixedly connected to the connecting rod 321. The transmission rack 322 meshes with the driven gear 34.

[0033] When the baffle 21 is closed, the moving plate 31 is in its initial position. At this time, the return spring 137 pushes the sliding block 312 to abut against the end of the slide rod 136 away from the diverter plate 12, and the roller 212 is located at the end of the arc groove 311 away from the inspection table 22. When the sliding plate 23 moves towards the baffle 21, the forward-rotating driven gear 34 drives the transmission rack 322 to move the moving plate 31 in the same direction, so that the roller 212 moves along the arc groove 311 towards the end of the arc groove 311 closer to the inspection table 22. During this process, the roller 212 drives the sliding seat 211 to slide on the baffle 21, and at the same time drives the baffle 21 to move towards the side of the conveyor belt 11, thereby opening the closed baffle 21. As the moving plate 31 moves, the return spring... When the sliding plate 23 moves away from the baffle 21, the driven gear 34 rotating in the opposite direction drives the transmission rack 322 to move the moving plate 31 in the same direction, so that the roller 212 moves along the arc groove 311 towards the end of the arc groove 311 away from the inspection table 22. During this process, the roller 212 drives the sliding seat 211 to slide in the opposite direction on the baffle 21, and at the same time drives the baffle 21 to move towards the middle of the conveyor belt 11, thereby closing the open baffle 21. As the moving plate 31 moves, the compressed return spring 137 restores its deformation. After the drive rack 242 separates from the drive gear 33, the return spring 137 abuts against the sliding block 312, preventing the moving plate 31 from moving, thereby ensuring that the baffle 21 can be continuously closed.

[0034] Furthermore, the sorting mechanism 2 also includes a jet nozzle 29, which is fixedly installed on one side of the discharge port 138 of the conveyor belt 11. The jet nozzle 29 is used to blow away unqualified medicinal materials on the conveyor belt 11.

[0035] When the inspection table 22 detects unqualified medicinal materials, and the unqualified medicinal materials are conveyed to the discharge port 138 by the conveyor belt 11, the jet nozzle 29 sprays air to blow away the unqualified medicinal materials, so that the unqualified medicinal materials are discharged from the discharge port 138.

[0036] This invention also provides a sorting and selection process for Chinese medicinal materials, which uses the aforementioned sorting and selection equipment. The specific steps are as follows: S1. The herbs to be picked are conveyed into the diversion plate 12. The diversion plate 12 diverts the herbs so that the diverted herbs enter each conveyor belt 11 one by one. S2. After the closed baffle 21 is opened and the first medicinal material is released, the sliding plate 23 drives the push plate 26 to move, so that the push plate 26 pushes the first medicinal material onto the inspection table 22 for inspection.
