Description

Technical Field

[0001] This utility model relates to the field of sorting equipment technology, and in particular to a structure for feeding and sorting Fritillaria cirrhosa. Background Technology

[0002] Because there are many counterfeit or closely related varieties with similar appearances on the market, such as Xinjiang Fritillaria, Iberia Fritillaria, and Lu Fritillaria, their authenticity identification and quality grading have become key links in ensuring the safety and efficacy of medicines.

[0003] Currently, the identification of genuine and counterfeit Fritillaria cirrhosa and its classification mainly rely on manual experience. The traditional manual sorting method distinguishes Fritillaria cirrhosa by observing its shape, color, surface texture and other characteristics. This method is inefficient, subjective, has a high error rate, and affects the uniformity and reliability of product quality.

[0004] To overcome the limitations of manual identification, intelligent identification methods based on machine vision have been gradually applied and researched. By constructing image datasets and employing techniques such as data fusion and deep learning, the morphological characteristics of Fritillaria cirrhosa and its main adulterants are described and extracted, leading to the construction of corresponding machine learning algorithm models. Although image recognition technology has become increasingly mature in feature extraction and classification, a key technical bottleneck remains in the engineering application of fully automated sorting of Fritillaria cirrhosa: the shape of Fritillaria cirrhosa is mostly irregular, near-spherical, rather than standard spheres, making it difficult for existing automated sorting equipment to handle effectively. For example, traditional vibratory feeders or conveyor belt feeding mechanisms cannot guarantee that Fritillaria cirrhosa with significant size differences can be stably, orderly, and in a single layer transported to the image acquisition area, easily resulting in material stacking, obstruction, or omission, severely affecting the accuracy of subsequent image recognition. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides a feeding and sorting structure for Fritillaria cirrhosa. To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

[0014] Furthermore, the material grading area also includes: a through-beam photoelectric switch; the photoelectric switch is disposed on the side wall of the guide tube and located between the guide V-groove and the electromagnetic gate, and a detection hole is opened on the guide tube at the transmitting and receiving positions of the photoelectric switch, and the diameter of the detection hole is smaller than the diameter of the smallest material to be inspected in the guide tube.

[0037] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] like Figure 1-17As shown in some illustrative embodiments, a feeding and sorting structure for Fritillaria cirrhosa is provided, including: a feeding area 100, a material arrangement area 200 and a material grading area 300, which are connected in sequence according to the flow direction of the Fritillaria cirrhosa to be tested.

[0039] The feeding area 100 is used to transport the Fritillaria cirrhosa (hereinafter referred to as the test material) to be tested to the material arrangement area 200 in a controllable, continuous and single-layer manner at a certain speed; the material arrangement area 200 is used to arrange the test material in a row and transport it to the material grading area 300; the material grading area 300 is mainly used to grade the test material according to its diameter and place the test material one by one onto other conveying devices.

[0040] like Figure 1-8 As shown, the feeding area 100 includes: a first motor 101, a drive gear 102, a feeding gear 103, a hopper 104, and a feeding ladder 105.

[0041] The first motor 101 requires a certain torque but not a very high speed, so a geared motor is typically used, with an adjustable speed of 0-20 RPM. The drive gear 102 is mounted on the power output shaft of the first motor 101. The first motor 101 operates under the control of an external electronic control system, driving the drive gear 102 to rotate synchronously. The drive gear 102 meshes with the feeding gear 103, thereby driving the feeding gear 103 to rotate clockwise.

[0042] The feeding gear 103 rotates along the guide groove 1041 opened in the hopper 104. Specifically, hollow grooves 1042 are opened on both sides of the hopper 104, and the hollow grooves 1042 accommodate part of the wheel body of the feeding gear 103. Arc-shaped guide grooves 1041 are opened on the front and rear walls of the hollow grooves 1042, and guide bars 1031 embedded in the guide grooves 1041 are provided on both the front and rear sides of the feeding gear 103. The guide bars 1031 are circular and fit with the guide grooves 1041 so that the guide bars 1031 rotate along the guide grooves 1041, thereby causing the feeding gear 103 to rotate on the hopper 104 under the drive of the first motor 101 and the drive gear 102.

[0043] Since space needs to be reserved in the center of the feeding gear 103 to install the feeding ladder 105, this application does not use a traditional bearing support structure. Instead, the feeding gear 103 is directly connected to the hopper 104, and the hopper 104 bears the rotational movement of the feeding gear 103, simplifying assembly while ensuring structural stability. However, since the above design will cause mechanical friction between the feeding gear 103 and the hopper 104, both are made of PEEK material with high strength and high wear resistance in this application. This material has high strength and high wear resistance, effectively extending the service life of the equipment.

[0044] The hopper 104 is equipped with an inclined slope 1043 that guides and conveys the material to be inspected 400 to the bottom outer edge of the feeding gear 103, ensuring that the material can continuously and automatically flow to the picking position. When the material to be inspected 400 is placed in the hopper 104, under the influence of gravity, it will flow along the inclined slope 1043 to the bottom outer edge of the feeding gear 103. Figure 4 The direction indicated by the arrow pointing to the flow direction of the material to be inspected.

[0045] A clearance groove 1035 is provided at the middle position of the feeding gear 103, and a feeding elevator 105 is located within the clearance groove 1035 to receive the material to be inspected 400 conveyed by the feeding gear 103. Several compartments 1032 are provided inside the feeding gear 103. The compartments 1032 are used to load the material to be inspected 400. As the feeding gear 103 rotates, the material to be inspected 400 enters the compartment 1032 from the lower position, is carried to the higher position, and then falls into the feeding elevator 105 extending from the clearance groove 1035 by its own gravity. The inlet 1033 of the compartment 1032 is located at the outer edge of the feeding gear 103 to receive the material to be inspected 400 entering from the lower position. The outlet 1034 of the compartment 1032 faces the rotation center of the feeding gear 103 and is connected to the clearance groove 1035 to output the material to be inspected 400 located at the higher position.

[0046] The feeding gear 103 is equipped with several stops 1036, which are spaced a certain distance apart to form a compartment 1032, so as to realize the loading of a small amount of material to be inspected 400 at a time.

[0047] The outer ends of the stop 1036 are provided with arc-shaped surfaces 1037 on both sides, so that the outer ends of two adjacent stop 1036 form a feeding port 1033 with a converging effect. The outer end of the stop 1036 refers to the end away from the center of the feeding gear 103. The above structural design can optimize the material picking effect, so that the feeding gear 103 can receive a small amount of material to be inspected 400 more smoothly, effectively avoiding the phenomenon of jamming or too much material in a compartment due to excessive material. It is also easier to carry the material to be inspected 400 for rotation.

[0048] The inner end of the stop 1036 bends and extends in the direction of rotation of the feeding gear 103 to form an extension 1038, so that a discharge port 1034 is formed between the inner ends of two adjacent stops 1036. The above structural design allows the material to be inspected 400 to fall from the discharge port 1034 in the direction of rotation of the feeding gear 103 and fall smoothly into the feeding elevator 105.

[0049] The feeding elevator 105 runs through the middle of the feeding gear 103 and is used to receive the material to be inspected 400 that falls out of the feeding gear 103 and send the material to be inspected 400 to the material arrangement area 200 by its own slope.

[0050] The feeding ladder 105 is an upward-facing pallet structure to receive the material to be inspected 400 that falls from the discharge port 1034 of compartment 1032 when compartment 1032 rotates to the high position. Figure 7 As shown. The inclined slope 1043 inside the hopper 104 guides and conveys the material to be inspected 400 to the inlet 1033 of the compartment where it has been rotated to a low position, as shown. Figure 6 As shown. The feeding elevator 105 is inclined, with the higher end of the feeding elevator 105 passing through the relief groove 1035, and the lower end of the feeding elevator 105 connected to the material arrangement area 200.

[0051] The material to be inspected 400 loaded into the hopper 104 slides into the compartment 1032 of the feeding gear 103 along the inclined slope 1043. As the feeding gear 103 rotates clockwise, the material to be inspected 400 loaded into the compartment 1032 is transported to a higher position by the feeding gear 103. When it approaches the highest point, it will be affected by gravity and fall out of the compartment 1032 along the guide of the extension 1038, and be sent into the feeding elevator 105. The structural design of the feeding area 100 can regularly lift the material to be inspected 400 in the hopper 104, ensuring the continuity of material conveying and the stability of the flow rate, and realizing continuous and controllable quantitative feeding. Moreover, the overall structure is more compact and simple, avoiding strong stirring, squeezing or throwing actions, and protecting the fragile Fritillaria cirrhosa from mechanical damage to the greatest extent.

[0052] like Figure 9 As shown, the material arrangement area 200 is used to arrange the materials 400 to be inspected, which may be stacked or clustered, from the feeding area 100 into a continuous and orderly single-row queue. Specifically, it includes: an arrangement roller 202 and a second motor 201 for driving the arrangement roller 202 to rotate.

[0053] The second motor 201 is controlled by an external electrical control system to rotate, driving the arranging roller 202 to rotate via a belt shaft and belt transmission device. The rotation of the arranging roller 202 requires a certain speed and torque, so the second motor 201 is typically a geared motor with an adjustable output speed of 0-100 RPM. The arranging roller 202 is tilted, with the end farther from the horizontal plane being the feeding side and the other end being the discharging side. The lower end of the feeding ladder 105 is inserted into the higher end of the arranging roller 202, feeding the material to be inspected 400 into the arranging roller 202. The lower end of the arranging roller 202 is connected to the material grading zone 300.

[0054] When the material to be inspected 400 enters the inclined arranging roller 202, it begins to rotate with the roller under the influence of the inner wall of the roller. During this process, the rotation of the arranging roller 202 provides the material to be inspected 400 with a continuous centrifugal force, causing it to adhere tightly to the inner wall of the roller. At the same time, due to the inclination of the arranging roller 202, gravity drives the material to be inspected 400 to move slowly from the feed side to the discharge side along the axial direction of the inner wall of the arranging roller 202. Under the combined action of centrifugal force and gravity, the material to be inspected 400 slides down inside the arranging roller 202. During this process, the material that was originally piled up will gradually disperse due to mutual collisions and rolling. Due to the limitation of the inner diameter of the arranging roller 202, the dispersed material will naturally tend to form a single-row queue at the lowest point of the arranging roller 202. As the arranging roller 202 continues to rotate, the material flows out steadily from the discharge side along the inclination direction of the arranging roller 202, and is finally conveyed to the material grading zone 300 in a single-row orderly state.

[0055] The structural design of the material arrangement area 200 can efficiently organize the disordered and stacked materials to be inspected 400 into a continuous and stable single-column queue. Compared with complex mechanical lever or baffle structures, the structure is simpler, more reliable, and less likely to damage the materials, thus maximizing the protection of the integrity of fragile medicinal materials such as Fritillaria cirrhosa.

[0056] like Figure 10-17 As shown, the material grading area 300 is used to grade the materials to be inspected in sequence according to the principle of approximate diameter. Specifically, it includes: a guide V-shaped groove 301, a vibration motor 302, a guide pipe 303, an electromagnetic gate 309, and a through-beam photoelectric switch 310.

[0057] The guide V-shaped trough 301 is at a certain angle to the horizontal plane, i.e., it is inclined. The end that is higher than the horizontal plane is the feed side, and the end that is lower is the discharge side. After the material to be inspected 400 is arranged and output from the material arrangement area 200, it enters the feed side of the guide V-shaped trough 301. The cross-section of the guide V-shaped trough 301 is V-shaped. The V-shape is mainly used to keep the arranged material to be inspected in an arranged state and to allow it to flow from the feed side to the discharge side along the overall slope of the trough.

[0058] A vibratory motor 302 is positioned at the bottom of the guide V-groove 301. The vibratory motor 302 is equipped with an eccentric wheel, which inserts into the circular groove below the guide V-groove 301. When the vibratory motor 302 rotates, its eccentric wheel exerts a thrust on the sidewall of the circular groove at a certain frequency, causing the guide V-groove 301 to sway in two directions along its long side. The vibratory motor 302 requires a certain rotational speed to generate the swaying frequency; typically, a geared motor adjustable from 0-1000 RPM is selected. The left-right swaying of the guide V-groove 301 allows the materials to be inspected entering the feed side to be arranged more orderly, not only avoiding material stacking caused by significant size differences but also preventing individual materials from getting stuck due to extreme irregularity.

[0059] The bottom of the V-shaped flow guide trough 301 has several grading holes. The material to be inspected 400 exhibits dimensional variations, with diameters typically ranging from 3mm to 25mm, and most commonly from 3mm to 14mm. Therefore, this application describes the grading process for materials with diameters between 3mm and 14mm. Specifically, the grading holes are arranged sequentially from the inlet side to the outlet side of the V-shaped flow guide trough 301: 2-4mm grading holes 401, 4-7mm grading holes 402, and 7-14mm grading holes 403.

[0060] During the conveying process, when materials with significant diameter differences, such as 3mm and 14mm particles, are adjacent, the mechanical limiting structure of the downstream sorting device cannot achieve precise particle-by-particle release control. Specifically, small-diameter materials may deviate due to excessive gaps, while large-diameter materials may become stuck, affecting the flow of subsequent materials. Therefore, this application uses 2-4mm grading holes 401, 4-7mm grading holes 402, and 7-14mm grading holes 403 to classify the materials, thereby ensuring the control accuracy of the subsequent sorting device.

[0061] The primary function of the grading orifices is to classify the arranged materials to be inspected according to the principle of approximate diameter. The grading orifices are elongated orifices with gradually changing radii, with the smallest orifice radius on the feed side near the guide V-groove 301 and the largest orifice radius on the discharge side near the guide V-groove 301. The materials to be inspected 400 first flow through the 2-4mm grading orifice 401, which has an inlet diameter of 2mm and an outlet diameter of 4mm. Materials within this size range can pass through this orifice, while materials larger than 4mm will flow through it. Next, the remaining materials flow through the 4-7mm grading orifice 402, where materials of 4-7mm size pass through. Finally, the materials flow through the 7-14mm grading orifice 403, where materials of 7-14mm size pass through. Thus, the materials to be inspected are graded according to the predetermined size range.

[0062] The guide tube 303 is connected to the grading holes, allowing the graded material to enter the corresponding guide tube 303; that is, each grading hole is connected to a guide tube 303. Specifically, the guide tube 303 connected to the 2-4mm grading hole 401 has a diameter of 6mm, the guide tube 303 connected to the 4-7mm grading hole 402 has a diameter of 9mm, and the guide tube 303 connected to the 7-14mm grading hole 403 has a diameter of 16mm, capable of accommodating the corresponding graded material to be inspected.

[0063] Each guide tube 303 is equipped with a photoelectric switch 310 and an electromagnetic gate 309. The electromagnetic gate 309 is installed on the guide tube 303, and the photoelectric switch 310 is installed on the side wall of the guide tube 303 and located between the guide V-groove 301 and the electromagnetic gate 309.

[0064] The electromagnetic gate 309, controlled by an external electrical control system, uses an electromagnet to drive the mechanical gate, releasing the materials to be inspected one by one from the guide tube 303. Specifically, it includes an electromagnet drive assembly 3091 and a double-forked gate mounted on the electromagnet drive assembly 3091. When the electromagnet drive assembly 3091 is energized, the double-forked gate will shift towards the electromagnet drive assembly 3091; it will reset after de-energization. The double-forked gate consists of two long gate plates 3092 and a short gate plate 3093 spaced a certain distance apart. Material passage holes 3094 are formed on the long gate plate 3092 at positions corresponding to the short gate plate 3093 for the passage of the materials to be inspected.

[0065] like Figure 16 As shown, after the electromagnetic gate 309 cooperates with the guide tube 303, when the electromagnet drive assembly 3091 is de-energized, both the long gate plate 3092 and the short gate plate 3093 are inserted into the guide tube 303, and the material to be inspected 400 is blocked by the short gate plate 3093 and cannot flow downward. Figure 17 As shown, after the electromagnet drive assembly 3091 is energized, the double-fork gate moves in the direction of the electromagnet drive assembly 3091. The first material to be inspected in the guide tube 303 flows downward and is blocked by the long gate plate 3092. When the electromagnet drive assembly 3091 is de-energized, the double-fork gate resets, and the first material to be inspected flows through the material passage 3094 on the long gate plate 3092 and flows down into the guide tube 303. At the same time, the short gate plate 3093 simultaneously blocks the second material to be inspected. The above describes the process of energizing and de-energizing the electromagnet gate 309, which is a complete single material to be inspected release process. By cyclically executing the above control flow, the materials to be inspected 400 in the guide tube 303 can be released one by one.

[0066] Detection holes are made at the transmitting and receiving positions of the photoelectric switch 310 corresponding to the flow guide tube 303. The diameter of the detection holes is smaller than the diameter of the smallest piece of material to be inspected in the flow guide tube, to prevent the material to be inspected from leaking out of the detection holes. The photoelectric switch 310 detects the obstruction of the openings in the flow guide tube 303, counts the number of pieces of material to be inspected passing through and the accumulation status inside the flow guide tube 303, which facilitates the external electrical control system to reasonably schedule the release of the three flow guide tubes 303. Based on the above structure, in conjunction with the external electrical control system, the quantity and accumulation status of the material in the three flow guide tubes 303 can be monitored in real time, and the electromagnetic gate 309 can be opened and closed in a time-sharing manner according to the detection results, so as to realize the orderly release of the material to be inspected 400 tube by tube. With the synchronous operation of the bottom transmission device (such as a conveyor belt), the final output is a discrete material flow with controllable spacing, providing stable and reliable feeding conditions for the subsequent vision inspection system.

[0067] The electromagnetic gate 309 reliably achieves the single material release action of blocking-releasing-blocking through a simple power-on-off cycle. The control logic is clear and the execution is precise. With the real-time monitoring of the through-beam photoelectric switch 310, the quantity and accumulation state of the material in each guide tube 303 can be accurately counted, so as to achieve orderly and balanced release of materials and ensure that the discrete material flow output has a controllable spacing.

[0068] The material grading zone 300 grouped materials of similar size into the same channel, ensuring that the subsequent electromagnetic gate 309 and photoelectric switch 310 could optimize the control of materials within a specific size range. This avoided the problem of small particles shifting due to excessive gaps or large particles blocking the entire process due to jamming, providing a highly uniform material flow for the downstream visual inspection system and significantly improving the overall system's recognition accuracy and processing efficiency.

[0069] The above structural design is designed for materials to be inspected with a diameter in the range of 3-14mm. Considering that the diameter range of the materials to be inspected also covers the size range of 14-25mm, more grading structures and supporting devices can be added to the material grading area based on existing principles, so as to achieve effective processing of materials to be inspected within this diameter range.

[0070] This application addresses the unique physical properties of Fritillaria cirrhosa, which exhibits significant diameter variations and irregular shapes. By employing quantitative enhancement in the feeding zone 100, single-row arrangement in the material arrangement zone 200, and size pre-screening in the material grading zone 300, it successfully achieves automated and continuous processing of irregular, variable-diameter spherical materials.

[0071] This application does not directly perform identification, but rather preprocesses the material for subsequent identification systems, creating the necessary working conditions. Through graded processing, this application groups mixed Fritillaria cirrhosa according to diameter range, ensuring uniform material size upon entering the visual identification station. Through single-row and particle-by-particle release control, the material is presented on the conveyor belt in a single, discrete, and controllable interval manner. This highly standardized material flow eliminates the need for subsequent image recognition systems to deal with complex stacking, occlusion, and size abrupt changes, enabling highly efficient and accurate image acquisition and authenticity identification, fundamentally improving the standardization and detection efficiency of the Fritillaria cirrhosa identification process. Furthermore, this application not only ensures the stability and consistency of the sorting process, thereby reducing the overall cost of sorting and counterfeit removal in current Fritillaria cirrhosa processes, but also ensures a high success rate for subsequent identification systems in eliminating counterfeit products through precise preprocessing.

[0072] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
