Description

Technical Field

[0001] This utility model belongs to the field of coal sorting technology, and in particular relates to a side-tilting flip-plate sorting system. Background Technology

[0002] In the subsequent processing of raw coal mined from underground, pre-treatment is required at a coal washing plant to remove lumpy gangue and debris such as wood blocks, iron blocks, and anchor bolts generated during underground production. Currently, most coal washing plants, after primary screening, feed raw coal lumps larger than 50mm onto a conveyor belt, where workers manually identify and remove gangue and debris beside the belt. A small number of coal washing plants use sorting machines to replace manual labor. There are currently two main types of sorting machines on the market: one uses a gantry robot / articulated arm robot in conjunction with an identification system to automatically select materials from the conveyor belt; the other uses an identification device installed on the conveyor belt, with a high-pressure gas ejection valve or mechanical plate / rod at the conveyor head striking the coal or gangue / debris. As the material falls, the gas is sprayed or struck, causing the coal and gangue / debris to fall into different chutes below for separation.

[0003] The use of robots for coal sorting in coal washing plants has the following disadvantages:

[0004] 1. Low single-unit processing capacity, with a maximum of 800-1200 sorting operations per hour;

[0005] 2. The weight of the material blocks to be sorted is limited;

[0006] 3. High-speed, heavy-load operations cause severe wear and tear on the robot, resulting in a short service life;

[0007] 4. Requires professional personnel for use, maintenance, and upkeep.

[0008] The blow-type material sorting method can only separate material blocks up to about 200mm in size; larger blocks are difficult to blow out. The types of materials that can be sorted are also limited, allowing only a maximum of two other materials to be separated from the original material, and sorting cannot be done by size. Mechanical push rods, on the other hand, suffer from high inertia, slow execution, low throughput, and easy wear of the mechanical structure. Currently, they are essentially on the verge of being phased out of the market and can only be used in specific scenarios requiring small sorting volumes and slow speeds.

[0009] Intelligent sorting machines are a new type of equipment for classifying and sorting solid raw materials and solid waste in mining that has been developed in the last ten years or so. In particular, they have begun to be used in coal preparation in recent years, and it is expected that they will have a broader market in various mining and mineral processing industries in the next few years.

[0010] Currently, most intelligent sorting machines on the market consist of identification devices mounted on belt conveyors, with the sorting process executed at the end of the conveyor. The sorting action uses air jets or push rods to strike the gangue, separating it from the coal and directing it into different feed troughs. This sorting method can only handle smaller particles. For large or extra-large gangue pieces exceeding 250mm in size, requiring high impact speed and force, there is currently a lack of suitable solutions. Utility Model Content

[0011] Based on the technical problems existing in the prior art, this utility model provides a side-flipping flip-plate sorting system to solve the above-mentioned technical problems.

[0012] A side-flipping sorting system includes a conveyor chain, an identification unit, a flipping structure, an execution structure, and a central control unit. The conveyor chain is circular. The identification unit is located above the starting position of the conveyor chain. The flipping structure is evenly arranged on the outer side of the conveyor chain. Several execution structures are provided on the inner side of the conveyor chain. The central control unit is signal-connected to the identification unit and also signal-connected to the execution structure.

[0013] A further improvement of this utility model is that the flap structure includes a first flap, a second flap, a first rod, a second rod, a first connecting piece, a second connecting piece, and a base. The base has a concave structure and is disposed on the conveyor chain. The first flap and the second flap are respectively disposed on both sides of the base.

[0014] Furthermore, both the first and second flaps are hinged to the base. A first rod is provided below the first flap, and a second rod is provided below the second flap. The end of the first flap near the base is hinged to the first end of the first rod. Even further, the end of the second flap near the base is hinged to the first end of the second rod, the second end of the first rod is hinged to the first end of the first connecting piece, and the second end of the first connecting piece is hinged to the lower part of the base near the end of the first flap.

[0015] Preferably, the end of the second flap near the base is hinged to the first end of the second rod, the second end of the second rod is hinged to the first end of the second connecting piece, and the second end of the second connecting piece is hinged to the lower part of the base near the end of the second flap.

[0016] A further improvement of this utility model is that: the execution structure includes a conical wheel, a motor, and a fixed base arranged in sequence. The fixed base is fixed to the inner side of the conveyor chain. The output end of the motor is connected to the conical wheel. The motor is used to drive the conical wheel to rotate. The motor is fixedly connected to the fixed base. The bracket is a concave bracket. The two ends of the conical wheel are arranged on the bracket.

[0017] A further improvement of this utility model is that it also includes a drive structure comprising a motor and a rotary encoder, the drive structure being used to drive the conveyor chain.

[0018] A further improvement of this utility model is that the middle of both the first flap and the second flap is recessed downwards.

[0019] A further improvement of this utility model is that: a collision prevention block is provided on the side of the middle of the first rod adjacent to the base, and a collision prevention block is provided on the side of the middle of the second rod adjacent to the base.

[0020] A further improvement of this utility model is that the rotational speed of the conical wheel is 10Hz to 50Hz.

[0021] A further improvement of this utility model is that the diameter of the conical wheel is greater than the width of the bracket.

[0022] Secondly, this utility model provides a side-flipping sorting method, based on the aforementioned side-flipping sorting system, comprising the following steps:

[0023] Place the block of material to be sorted onto the flip-plate structure;

[0024] The flip-plate structure passes through the identification device driven by the conveyor chain. The identification device acquires the code of the flip-plate structure and the physical information of the material block to be sorted.

[0025] The physical information and encoding are uploaded to the central control unit, which then generates control commands based on the physical information and encoding and sends them to the execution structure.

[0026] The execution structure triggers the flip-plate structure according to the control command, causing the material blocks to be sorted on the flip-plate structure to fall and complete the sorting.

[0027] A further improvement of this invention is that the physical information includes the mass and speed of the material blocks to be sorted.

[0028] Compared with the prior art, the technical solution of this utility model has the following beneficial technical effects:

[0029] This invention, by placing the identification unit at the beginning of the conveyor chain, completes the real-time classification of coal and gangue in advance, allowing sufficient time for subsequent actions and avoiding missed detections. The flip-plate structure is evenly distributed along the outer side of the chain, forming a continuous sorting station, increasing the processing capacity per unit time by more than 30%. The execution structure is located on the inner side of the conveyor chain to trigger the flip-plate structure. The central control unit performs closed-loop control to complete the identification → positioning → triggering in one step, achieving a sorting accuracy rate of ≥98% and reducing manual re-inspection.

[0030] This invention achieves bidirectional sorting on the same base by symmetrically setting up a flap structure. The structure is compact, has no sliding groove friction, and reduces the risk of jamming.

[0031] This invention uses a conical wheel, motor, and fixed base to form an embedded high-speed triggering unit, which can complete the flipping action upon collision, with low power requirements and fast triggering speed.

[0032] This invention uses a motor and rotary encoder to drive the conveyor chain in a closed loop, providing real-time feedback on the chain link position to ensure that the error in the identification-trigger-flipping time window is ≤2mm, thereby improving sorting accuracy.

[0033] This invention features a recessed design in the middle of the first or second flap to form a self-centering groove for materials, preventing coal blocks from slipping, improving flap utilization, and reducing missed picking.

[0034] This invention absorbs the impact of the flap returning to its original position by setting anti-collision blocks on the first and second rods, thereby reducing noise and hinge wear and extending the maintenance cycle by ≥30%.

[0035] This invention uses a cone wheel with a diameter greater than the support width to create an adjustable collision point on the outward-extending inclined surface, simplifying installation and accommodating various flip-up heights. Attached Figure Description

[0042] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These embodiments should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0043] Example 1

[0044] like Figure 1-2 As shown, a side-flipping sorting system includes: a conveyor chain 1, an identification unit 2, a flipping structure 3, an execution structure 4, a drive structure 5, and a central control unit. The conveyor chain 1 is circular, and the drive structure 5 drives the conveyor chain 1. Several flipping structures 3 are evenly arranged on the outer side of the conveyor chain 1, and several execution structures 4 are arranged on the inner side of the conveyor chain 1. The flipping structures 3 are used to carry blocks of material to be sorted. The identification unit 2 is located above the conveyor chain 1 and is used to acquire the physical parameters of the blocks of material to be sorted carried by each flipping structure 3. The physical parameters are transmitted to the central control unit via signal transmission. The central control unit controls the execution structure 4 to trigger the flipping structure 3 according to the physical signals and the unique code of each flipping structure 3, thereby selecting the blocks of material to be sorted on the flipping structure 3.

[0045] Specifically, such as Figure 3-4As shown, the flap structure 3 includes a first flap 311, a second flap 312, a first rod 321, a second rod 322, a first connecting piece 331, a second connecting piece 332, and a base 34. The base 34 has a concave structure and is disposed on the conveyor chain 1. The first flap 311 and the second flap 312 are respectively disposed on both sides of the base 34 and are hinged to the base 34. A first rod 321 is provided below the first flap 311, and a second rod 322 is provided below the second flap 312. The end of the first flap 311 near the base 34 is connected to the first connecting piece 332. The first end of rod 321 is hinged, and the end of the second flap 312 near the base 34 is hinged to the first end of the second rod 322. The second end of the first rod 321 is hinged to the first end of the first connecting piece 331, and the second end of the first connecting piece 331 is hinged to the lower part of the base 34 near the first flap 311. The end of the second flap 312 near the base 34 is hinged to the first end of the second rod 322, and the second end of the second rod 322 is hinged to the first end of the second connecting piece 332. The second end of the second connecting piece 332 is hinged to the lower part of the base 34 near the second flap 312. By applying force to the second end of the first rod 321 or the second rod 322, the first flap 311 or the second flap 312 is moved to slide, thereby sliding the material block carried on the first flap 311 or the second flap 312 down, thus completing the sorting.

[0046] Specifically, the flap structures 3 are arranged at preset intervals on the conveyor chain 1. Multiple flap structures 3 can simultaneously process the sorting of multiple material blocks, improving sorting efficiency. Each flap structure 3 has a unique label for easy subsequent control.

[0047] In a preferred embodiment, the flap structures 3 are arranged along the bearing surface of the conveyor chain 1 at equal pitches T. The pitch T is set based on the material length L and the conveyor chain speed v, maintaining a gap of 1.2L between adjacent flap structures 3, thus avoiding stacking and ensuring 100% coverage. The pitch error is controlled within ±0.5mm by CNC drilling jig positioning, ensuring that all flap structures pass through the execution structure 4 synchronously. A unique QR code and decimal ID (such as 0037, 0038, etc.) are laser-engraved on the side of the base 34 of each flap structure 3, and RFID tags are implanted on the chain links. The central control unit obtains the identity and position of the flap structure in real time through the reader / writer, realizing "one flap, one file". During the system power-on self-test, it automatically checks the ID sequence, and alarms and stops if the ID is missing or duplicated. During operation, after identification unit 2 scans the coal block, the central control unit locks the target flipper 3-5 cycles in advance based on the current chain speed and ID mapping table, and issues a flipping command. Even if the chain speed fluctuates, the encoder closed-loop compensation still ensures that the command arrival error is <±2mm. The parallel operation of the multi-flipper structure 3 greatly improves the processing speed and throughput. When any flipper structure 3 fails, 2 can be shielded online without affecting the overall operation, significantly improving the continuity and efficiency of coal sorting.

[0048] Specifically, both the first flap 311 and the second flap 312 are designed with a downward-recessed "√"-shaped material receiving groove in the middle. The material receiving groove is welded from two steel plates, with a rounded transition radius of R5 mm at the apex of the included angle, ensuring strength while avoiding stress concentration. The depth of the recess gradually changes along the conveying direction, with the front end being less than the rear end, causing the center of gravity of the material block to automatically shift backward and preventing the material block from rushing forward during sudden stops. Both the first flap 311 and the second flap 312 have protective edges on both sides, forming a semi-enclosed guide channel. The steel plate surface is shot-blasted and covered with a 2mm polyurethane lining, increasing the friction coefficient to 0.45, which increases gripping force and reduces noise. The entire "√"-shaped recess is coplanar with the hinge axis of the base 34, allowing the material block to slide smoothly down the slope without residue when the flap rotates 90°. Two rows of φ4mm drainage holes are opened at the bottom of the recess to prevent coal slime from accumulating and freezing. This structure keeps the material's center of gravity below the hinge axis of the flap throughout the entire 0° to 90° range, significantly improving conveying stability and sorting reliability.

[0049] Specifically, a bumper block is provided on the side of the first rod 321 adjacent to the base 34, and a bumper block is provided on the side of the second rod 322 adjacent to the base 34. Each bumper block includes a pin and a nut. A through hole is formed in the middle of both the first rod 321 and the second rod 322, and a pin is provided at the through hole. The exposed portion of the pin is close to the base, and a nut is provided on the exposed portion of the pin. The nut serves as a bumper and a limiting element. The pin is made of stainless steel, and the exposed portion of the pin is nickel-plated for rust prevention. The outer edge of the nut is rounded, acting as an elastic bumper block to absorb impact and preventing loosening through threaded locking adhesive. When the flap structure 3 returns to its original position, the bumper block contacts the side of the base 34 first, forcing the flap structure 3 to stop before reaching its mechanical dead point, avoiding hinge overshoot and hard collisions. The nut reduces peak impact force and noise; after long-term wear, only the nut needs to be replaced. The nut can be colored differently to indicate the maintenance cycle. It simultaneously meets the four requirements of anti-collision, noise reduction, limit positioning, and easy maintenance, significantly extending the service life of the flip-plate structure 3 and improving the overall operational reliability of the machine.

[0050] In a preferred embodiment, an 8PPR incremental rotary encoder is coaxially mounted at the end of the hinge pin of the first connecting piece 331 or the second connecting piece 332. Its A and B phase pulses are differentially driven into the high-speed counting port of the central control unit. The software uses a quadruple frequency multiplication technique to achieve a resolution of 32cpr, corresponding to 0-256 count values ​​outputting across the 0°-90° travel of the flip plate, with a real-time angle resolution of 0.35°. Each time the system powers on, it automatically zeros the scale based on the horizontal position of the flip plate. Combined with a 5ms interrupt sampling, angle closed-loop correction can be completed within 30ms, reducing the sorting position error from ±3° to within ±1°. The encoder body uses a metal code disk and a wide-temperature bearing (-40℃ to +85℃), with an IP54 protection rating, making it dust-resistant and vibration-resistant. The maintenance cycle is extended from six months to over one year, significantly improving the accuracy and reliability of coal sorting.

[0051] As a preferred embodiment, the center distance of each hinge in the flap structure 3 is precisely calculated based on the dead point trajectory of the four-bar linkage with a 10% safety margin, ensuring that the dead point is always outside the flap at the working swing angle, maintaining unidirectional torque throughout the 0° to 90° range, and preventing jamming; the hinge pin is made of 45 steel, heat-treated and plated with 0.02mm hard chrome, with a hardness of HV800 or higher, making it corrosion-resistant and wear-resistant; the lubrication-free bushing is made of oil-impregnated copper-based powder metallurgy, requiring no maintenance for life after one press-fitting, with a friction coefficient ≤0.12, significantly reducing noise and energy consumption, and improving the overall reliability of the machine.

[0052] Specifically, such as Figure 5The execution structure 4 shown includes a conical wheel 41, a motor 42, and a fixed base 43 arranged in sequence. The fixed base 43 is fixed to the inner side of the conveyor chain 1. The output end of the motor 42 is connected to the conical wheel 41. The motor 42 is used to drive the conical wheel 41 to rotate. The motor 42 is fixedly connected to the fixed base 43. The bracket 44 is a concave bracket. The protrusions at both ends of the bracket 44 are connected to the two ends of the conical wheel 41. The conical wheel 41 rotates on the bracket 44 under the drive of the motor 42.

[0053] Specifically, the rotational speed of the conical wheel 41 is 10Hz to 50Hz. The conveyor chain 1 drives the flip structure 3 to approach the inclined surface of the conical wheel 41, thereby breaking the balance of the flip structure 3 and completing the sorting action. The sorting action has low power requirements and fast execution speed.

[0054] Specifically, the diameter of the conical wheel 41 is designed to be larger than the width of the bracket 44, allowing the inclined surfaces on both sides of the conical wheel to naturally extend outward by 2-4mm, forming an adjustable collision flange. By changing the lateral installation position of the fixed seat 43 inside the conveyor chain, the contact height between the inclined surface and the flip structure 3 can be finely adjusted, achieving collision point control with a precision of 0.5mm. The extended inclined surface generates an instantaneous impact with a linear velocity of 0.3-1.5m / s at a rotation speed of 10Hz-50Hz, completing the tilting action from 0° to 90°. By designing the diameter of the conical wheel 41 to be larger than the width of the bracket 44, no additional sensors are required. This diameter redundancy design simplifies assembly and is compatible with flip structures of different thicknesses, significantly improving sorting speed and reliability.

[0055] Specifically, it also includes a drive structure 5 comprising a motor and a rotary encoder. The drive structure is used to drive the conveyor chain 1, and the rotary encoder is used as a sensor to convert the mechanical rotation angle into an electrical signal to assist in the subsequent control process.

[0056] In a preferred embodiment of this invention, the conical wheel 41 adopts a double-conical surface design with a cone angle ∈ [30°, 45°], corresponding to a slope of 2.5mm to 4mm, allowing for stepless speed regulation within the range of 10Hz to 50Hz. The wheel body of the conical wheel 41 is made of aluminum alloy with a hard anodized surface treatment, ensuring wear resistance while maintaining lightweight construction. Each end of the conical wheel 41 is equipped with a bearing, which is located within the protrusions of the support 44 at both ends to achieve low-friction rotation.

[0057] In a preferred embodiment of this invention, a rubber pad is provided between the bracket 44 and the fixed base 43 to absorb impact and reduce noise. A PU rubber ring is provided on the outer edge of the conical wheel 41 to reduce impact noise.

[0058] Example 2

[0059] The side-flipping sorting method of the side-flipping sorting system of this utility model will be further described below with reference to Embodiment 2. Based on a side-flipping sorting system in Embodiment 1, the side-flipping sorting method includes the following steps:

[0060] Place the block of material to be sorted on the flip-plate structure 3;

[0061] The flip structure 3 passes through the identification device 2 under the drive of the conveyor chain 1. The identification device 2 obtains the code of the flip structure 3 and the physical information of the material block to be sorted.

[0062] The physical information and encoding are uploaded to the central control unit, which generates control commands based on the physical information and encoding and sends them to the execution structure 4.

[0063] The execution structure 4 triggers the flip structure 3 according to the control command, causing the material blocks to be sorted on the flip structure 3 to fall and complete the sorting.

[0064] Specifically, the physical information includes the speed and mass of the material block, and the encoding is a unique code corresponding to the flip structure 3.

[0065] Specifically, the material blocks to be sorted are placed stably in the "√"-shaped receiving trough of the flip structure 3. The flip structure 3 moves forward at a constant speed with the conveyor chain 1, and first, identification is triggered by the inlet photoelectric switch. When the flip structure 3 passes the identification device 2, the identification device 2 reads the QR code and RFID tag on the side wall of the base 34 to obtain the unique code of the flip structure. On the other hand, it collects physical information such as the color, particle size, and density of the material blocks and immediately packages them into data frames. The data frames are transmitted to the central control computer via Ethernet. The central control computer completes the coal / gangue identification and calculates the remaining time and chain link number for the flip structure 3 to reach the execution structure 4 based on the code, generating control commands containing trigger phase, cone wheel speed, and delay compensation. The control command is sent to the motor 42 of the execution structure 4. The motor 42 accelerates the conical wheel 41 to the target frequency according to the set curve, and outputs a precise impact at the moment when the edge of the flip structure 3 enters the collision zone, impacting the first rod 321 or the second rod 322 of the flip structure 3, so that the flip structure 3 completes the 0°→90° flip within 30ms; the material block slides freely along the inclined plane to the corresponding collection box, realizing efficient, low-consumption and error-free automatic sorting.

[0066] Specifically, after the flip structure 3 completes its flipping, the original path to the collection box is replaced by a conveyor belt arranged perpendicular to the conveyor chain 1, forming a rapid transfer system with "chain-belt" coordination. The conveyor belt uses a PVC anti-slip surface, has a width of 600mm, a belt speed of 1.2m / s, and is directly connected to the downstream production line. Its drive roller is linked to the central control machine and can automatically start within 0.3 seconds after the flipping action is triggered, ensuring that coal or gangue is carried away the instant it leaves the flip structure 3, avoiding secondary accumulation. Adjustable skirts with a height of 80mm are added to both sides of the conveyor belt to prevent material from spilling sideways; two sets of buffer rollers are installed under the belt surface to absorb the impact of falling material and extend the belt's life. By replacing conveyor belt modules of different lengths, it can flexibly connect to crushing, washing, or loading processes, enabling immediate transfer after sorting and continuous operation without manual handling of the collection box, improving site utilization and sorting efficiency.

[0067] Specifically, when the first rod 321 or the second rod 322 of the flap structure 3 is impacted, it causes the flap structure to pass the dead point. Taking the first rod 321 as an example, the conical wheel 41 rotates at a constant speed under the drive of the motor 42. When the coded ID of the flap structure 3 is detected to be about to enter the collision window, the edge of the conical wheel 41 already has tangential velocity. The conical wheel 41 collides with the first rod 321, and a clockwise torque M is generated instantaneously at the impact point. The torque M is transmitted to the first connecting piece 331 through the first rod 321, causing the first connecting piece 331 to start rotating around the lower hinge point of the base 34. At this time, the flap structure 3 is in a critical state of "dead point"; the frictional resistance between the first connecting piece 331 and the hinge of the base 34 is at its maximum. When the flap structure 3 passes the dead point, the potential energy drops sharply, and the motion enters the self-acceleration zone. After passing the dead point, the center of gravity of the first flap 311 begins to be lower than the hinge axis, and the gravitational torque quickly becomes the main driving force. As the angular velocity of the first rod 321 increases, the first flap 311 swings rapidly downwards under its own weight, and the center of gravity of the material block descends synchronously. The material block is guided downwards by a "√"-shaped recessed groove, completing the sorting process. When the first flap 311 swings downwards, the anti-collision block in the middle of the first rod 321 contacts the base 34, generating a counter-torque to prevent metal-on-metal impact noise and hinge overload.
