Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sorting equipment, in particular, to a flexible sorting disc surface treatment and material guiding method, system, device and storage medium. BACKGROUND

[0002] In the field of discrete material automatic feeding, the existing technology mainly uses vibrating disc, flexible vibrating disc, 3D vision guiding and other schemes to realize the separation, sorting and feeding of materials. These technologies replace the traditional manual sorting and feeding mode through mechanical vibration, visual recognition or flexible driving, which improves the production automation degree to a certain extent, reduces the low efficiency and error problems caused by manual intervention, meets the basic needs of continuous material feeding in some industrial scenes, and provides a foundation support for the stable operation of automatic production line.

[0003] However, the existing technology still has some problems: the traditional vibrating disc has fixed overall structure and is usually customized for specific materials, which has poor flexibility and needs to be redesigned and debugged when replacing materials, and has low adaptability; the flexible vibrating disc has improved material adaptability, but its feeding speed is slow, which is difficult to meet the high-speed production demand. In addition, the surface friction coefficient of the existing sorting turntable is uniformly distributed, which cannot adapt to the change of the movement characteristics of the materials from the center to the edge, resulting in easy slipping of the materials in the center area, collision of the materials in the edge area due to friction mutation, and high rate of bruising and collision. The surface texture design is single and lacks gradient change, which cannot guide the materials to form an orderly movement trajectory, further increasing the risk of material stacking and jamming. At the same time, most sorting discs do not take into account the anti-static performance, and the materials are easy to stick together due to static adsorption, which seriously restricts the sorting efficiency and feeding stability. These deficiencies in surface treatment have become a key bottleneck restricting the flexibility and speed improvement of sorting equipment. Therefore, there is an urgent need for an automatic feeding scheme with relatively large flexibility, relatively fast feeding speed and the ability to reduce material damage and sticking by optimizing surface treatment characteristics and improve the controllability of movement trajectory. SUMMARY

[0004] The main purpose of the present application is to provide a flexible sorting disc surface treatment and material guiding method, which aims to solve the technical problems of the existing discrete material automatic scheme with relatively small flexibility, relatively slow feeding speed and easy bruising, stacking, jamming and material damage and sticking of materials.

[0005] The present application provides a flexible sorting disc surface treatment and material guiding method, which comprises:

[0006] The sorting turntable comprises a radial gradient composite coating with gradually decreasing friction coefficient from the center to the edge of the sorting turntable, and the radial gradient composite coating comprises a friction texture with gradually decreasing texture density from the center to the edge of the sorting turntable.

[0007] The replenishment bin buffers the material, and replenishes the material to the sorting turntable when the sorting turntable is short of material;

[0008] The sorting turntable starts to rotate, and the material is pushed to the edge of the sorting turntable under the rotation of the sorting turntable;

[0009] A first screening mechanism performs Z-direction surface cutting on the material, and pushes back the material with a height exceeding a set value or overlapping to the center of the sorting turntable;

[0020] When the material state sensor detects that the feeding position is empty and the discharging position is empty, the posture adjusting mechanism reverses the material in time to control the material to complete the posture adjusting action after the repeated precision of the material stopping at the feeding position.

[0021] In one of the schemes, before the material slides to the discharging conveying mechanism, further comprising:

[0022] acquiring the discharging state of the feeding position through a discharging state sensor;

[0023] When the discharging state sensor detects that the discharging state is a full state, the full gate is closed to prevent the material from entering the discharging conveying mechanism;

[0034] The discharge conveying control module is connected with the discharge conveying mechanism, and is used for adjusting and controlling the conveying speed of the material conveyed to the posture adjusting mechanism or the feeding position.

[0035] In one of the schemes, a posture adjusting control module is further included, which is connected with the posture adjusting mechanism and the material state sensor respectively, and is used for receiving the material state sensor signals of the feeding position and the discharge position, so as to control the posture adjusting mechanism to adjust the posture of the material passing through the discharge conveying mechanism, and control the stopping repetition accuracy of the material at the feeding position.

[0036] In one of the schemes, a full material control module is further included, which is connected with the driving device of the full material gate and the discharge state sensor respectively, and is used for receiving the discharge state sensor signals, so as to detect the full material state of the feeding position, and control the opening and closing actions of the full material gate.

[0037] In one of the schemes, a man-machine interaction module configured with a touch screen is further included, which is connected with the main control unit, and is used for receiving the parameter settings input by a user, and displaying the equipment running state in real time.

[0038] The application further provides a flexible material sorting turntable surface treatment and material guiding equipment, which comprises:

[0039] one or more processors;

[0040] a memory storing one or more programs, which, when executed by the one or more processors, cause the one or more processors to implement the flexible material sorting turntable surface treatment and material guiding system as described above.

[0041] The application further provides a storage medium containing computer executable instructions, which, when executed by a computer processor, are used to execute the flexible material sorting turntable surface treatment and material guiding method as described above.

[0042] The working principle and beneficial effects of the application are as follows:

[0043] 1. Through the automatic feeding function of the feeding bin and the rotation drive of the sorting turntable, the material can be continuously provided for the sorting process, and the centrifugal force is used to realize the preliminary dispersion of the material, so as to realize the effects of reducing manual intervention and ensuring the continuity of sorting; through the Z-direction surface cutting of the first screening mechanism, the radial screening of the second screening mechanism, the gap separation of the inclined blocking, the posture recognition of the third screening mechanism and the blowing and removing, the material can be accurately screened layer by layer from the height, radial size, spacing to the final posture, and then the material posture is unified and the material stacking is avoided, so as to realize the effects of improving the material feeding accuracy and reducing the risk of small size material jamming; through the overturning function of the posture adjusting mechanism, the sensor detection of the feeding position and the discharging position, and the logical control of the main control unit, the material posture can be dynamically adjusted according to the production demand, and the stopping and repeating accuracy of the material at the feeding position can be controlled, so as to match the demand of the production link for the material posture and the gap feeding, and realize the effect of flexible adaptation to different working conditions; through the pneumatic drive of the full gate, the full material state sensor of the feeding position, and the linkage control of the main control unit, the sorting outlet can be quickly locked when the discharging conveying is full, and the discharging can be restored when it is not full, so as to coordinate the rhythm of sorting and discharging, realize the effect of non-stop operation of the sorting machine, and avoid material accumulation and blockage; through the cooperation of the core control of the main control unit and the sensing detection module, the feeding control module, the screening control module and the like, and the touch screen parameter setting of the man-machine interaction module, the whole process automatic control and real-time state monitoring can be realized, so as to simplify the equipment operation and support flexible adjustment of processing parameters, realize the effects of reducing the equipment use threshold, improving the system adaptability and expansibility; through the above cooperation, the overall flexibility range of the sorting equipment can be improved, the overall feeding speed of the sorting equipment can be accelerated, and the overall cost of the sorting equipment can be controlled, solving the problems of relatively small flexibility range and relatively slow feeding speed of the existing discrete material automation scheme;

[0044] 2. Through the radial gradient composite coating on the surface of the sorting turntable and the matching friction texture design, the motion guiding defects of the traditional sorting disc can be solved from the surface characteristic dimension: the friction coefficient decreases from the center to the edge, and the texture density gradually decreases, so that the material realizes seamless transition from "stable driving" to "smooth sliding" under the action of centrifugal force, effectively controls the radial speed change, and significantly reduces the risk of bumping damage; at the same time, the anti-static performance of the composite coating reduces the material adhesion, the gradient texture enhances the controllability of the trajectory, cooperates with the multi-stage screening mechanism, further improves the material sorting accuracy and feeding speed, enhances the adaptability of the equipment to different weights and shapes of materials, and solves the technical problems of bumping and stacking, jamming and material damage and adhesion of the existing discrete material automation scheme.

[0052] Referring to Figs. 1-2 One embodiment of the present application provides a flexible sorting disc surface treatment and material guiding method, comprising:

[0053] The sorting disc surface comprises a radial gradient composite coating with a gradually decreasing friction coefficient from the center to the edge of the sorting disc, and the radial gradient composite coating comprises a friction texture with a gradually decreasing texture density from the center to the edge of the sorting disc; a material supplement bin is used to supplement the material to the sorting disc when the sorting disc is out of material; the sorting disc starts to rotate, and the material is pushed to the edge of the sorting disc under the rotation of the sorting disc; a first screening mechanism performs Z-direction surface cutting on the material, and pushes back the material with a height exceeding a set value or overlapping to the center of the sorting disc; a second screening mechanism performs radial screening on the material passing through the first screening mechanism, and retains the material passing in a minimum size posture in the radial direction, and the material that does not pass is slid back to the center of the sorting disc through the slope surface of the sorting disc; a slanting stopper makes the material passing through the second screening mechanism slide to the edge of the sorting disc, so that gaps are generated in the circumferential direction of the material; a third screening mechanism performs posture judgment on the material passing through the slanting stopper, and when the posture judgment result is OK, the material is slid to a discharging conveying mechanism through a discharging stopper, and when the posture judgment result is NG, the material is returned to the center of the sorting disc through a blowing electromagnetic valve; and the discharging conveying mechanism discharges the material passing through the third screening mechanism.

[0054] It should be noted that the friction coefficient gradient of the radial gradient composite coating can be realized by adjusting the coating material ratio. Taking Teflon as the base material, and taking graphene as the example of composite anti-static agent and taking silicon dioxide powder as the example of friction-enhancing additive:

[0055] The sorting disc can be divided into a center area, a transition area and an edge area. The center area can be selected from 50%-60% Teflon, 5%-15% graphene and 10%-20% silicon dioxide powder, the transition area can be selected from 60%-75% Teflon, 6%-10% graphene and 5%-10% silicon dioxide powder, and the edge area can be selected from 75-85% Teflon, 5%-8% graphene and less than 5% silicon dioxide powder.

[0056] The processing of the radial gradient composite coating can be realized by segmented spraying and solidification process, and the processing steps can include:

[0057] The material sorting turntable is divided into concentric ring regions according to radial partitioning and segmented spraying, wherein each region is pre-set with corresponding material ratio and spraying parameters, to ensure uniform coating composition in the same region and smooth transition of composition between different regions; after spraying, stepwise curing treatment (temperature gradually increases from 120°C to 200°C, and holding time increases with the region) is performed, so that the coating with different ratios can be fully crosslinked, to ensure the bonding force and wear resistance;

[0058] The friction texture of the radial gradient composite coating can be realized by laser micro-machining technology, wherein different texture densities can be machined corresponding to the aforementioned center region, transition region and edge region. The texture density of the center region can be 50-80 microgrooves per square millimeter, with a depth of 5-10 μm. The texture density of the edge region can be 10-30 microgrooves per square millimeter, with a depth of 2-5 μm. The texture density of the transition region can gradually decrease from the texture density of the center region to the texture density of the edge region.

[0059] Specifically, the material shortage detection of the material sorting turntable can be realized by installing a proximity switch sensor in a specific region of the material sorting turntable, such as near the center position. When the number of materials in the sensor sensing range is lower than the pre-set threshold, it is determined that the material sorting turntable is short of materials. The pre-set threshold can be determined comprehensively according to the volume, density of the materials and the amount of materials required for normal operation of the material sorting turntable, etc.

[0060] The material supplement bin is used to buffer materials, and its design can be determined according to the characteristics and storage requirements of the materials. For example, for materials with poor flowability, the internal structure of the material supplement bin can be designed as a bucket with a certain inclination angle, and a vibration device is arranged on the bucket wall. The vibration frequency can be adjusted within the range of 10-50 Hz to ensure smooth sliding of the materials. The buffering capacity of the material supplement bin is determined according to the production rhythm and material consumption speed.

[0061] The material sorting turntable is driven to rotate by a driving motor. The driving motor can be an alternating current asynchronous motor, and its speed can be continuously adjusted within the range of 0-50 rpm. The speed adjustment of the alternating current asynchronous motor can be realized by a frequency converter. The operator can input the corresponding speed value in the human-computer interaction interface according to the weight, shape and sorting efficiency requirements of the materials, to accurately control the speed of the material sorting turntable. For example, for materials with light weight and regular shape, the speed can be set to 30-50 rpm to improve the sorting efficiency. For materials with heavy weight or irregular shape, the speed can be set to 10-30 rpm to prevent the materials from being damaged due to excessive centrifugal force.

[0062] The first screening mechanism can screen the material in the Z direction. The Z direction height adjustment can be realized by the screw nut mechanism cooperating with the stepper motor. The step angle accuracy of the stepper motor can reach ±0.01°, so as to accurately control the height adjustment of the first screening mechanism in the range of 0-30 mm. For example, when processing the material with a height of 8 mm, the Z direction height of the first screening mechanism can be set to 10 mm, so as to ensure that the material with a height exceeding the set value or overlapping is pushed back to the center of the material sorting turntable.

[0063] The second screening mechanism can screen the material in the radial direction. The radial position adjustment can be realized by the linear guide cooperating with the servo motor. The positioning accuracy of the servo motor can reach ±0.05 mm. The operator can accurately adjust the position of the second screening mechanism according to the minimum radial size of the material, so as to realize the radial screening of the material. For example, for the material with a minimum radial size of 5 mm, the second screening mechanism can be adjusted to the corresponding position with a radial size of 5 mm, so as to only allow the material with the minimum size to pass through.

[0064] The third screening mechanism can judge the posture of the material and detect it by using the visual sensor. When the posture judgment result is NG, the material is blown back to the center of the material sorting turntable by the blowing electromagnetic valve. Ideally, the response time of the blowing electromagnetic valve should be less than 8 ms. The operator can adjust the air pressure according to the weight, volume and other factors of the material. The compressed air pressure can be adjusted in the range of 0.4-0.6 MPa, so as to ensure that the unqualified material can be blown back to the center without affecting the surrounding materials.

[0065] The discharge conveying mechanism can adopt the motor belt driving mode. The motor power can be determined according to the weight of the conveyed material, the conveying speed and the belt length and other factors. Specifically, the conveying speed can be continuously adjusted in the range of 0-30 m / min, which is realized by adjusting the output frequency of the motor. For example, if the receiving speed of the downstream equipment is 20 m / min, the conveying speed of the discharge conveying mechanism is set to 20 m / min, so as to ensure stable conveying of the material.

[0066] In one embodiment, the posture adjustment mechanism receives the material from the discharge conveying mechanism according to the production requirements, adjusts the posture of the material passing through the discharge conveying mechanism, and controls the stopping repetition accuracy of the material at the feeding position. The posture adjustment mechanism discharges the material after the posture adjustment.

[0067] In one embodiment, the posture adjustment step includes: obtaining the material state of the feeding position and the discharging position by a material state sensor; when the material state sensor detects that the feeding position has material, the posture adjustment mechanism does not act; when the material state sensor detects that the feeding position has no material and the discharging position has material, the posture adjustment mechanism overturns the material to complete the posture adjustment action; when the material state sensor detects that the feeding position has no material and the discharging position has no material, the posture adjustment mechanism delays the overturning of the material to control the completion of the posture adjustment action after the stop repeat precision of the material in the feeding position.

[0068] Specifically, the input end of the posture adjustment mechanism is connected with the discharging conveying mechanism, and the discharging conveying mechanism can receive the material through a profiling groove or a rotating channel; a rotating assembly driven by a servo motor can be used to realize the 90-degree or 180-degree overturning of the material, so as to ensure that the posture of the material meets the production requirements, such as adjusting the material from a "side standing" state to a "front flat" state; the discharging can use a pneumatic push rod to push the material to the downstream equipment.

[0069] The material state sensor of the feeding position can be an optical sensor to detect the material state in real time, and the detection signal can be transmitted to the corresponding control system through an I / O interface to cooperate with the rotating assembly:

[0070] When the feeding position sensor detects "material", the posture adjustment mechanism remains stationary, and the rotating assembly and the pushing device do not act, so as to avoid material accumulation; when the feeding position sensor detects "no material" and the discharging position sensor detects "material", the control system immediately triggers the rotating assembly to act: the servo motor drives the material to overturn to the target posture, and then pushes it to the feeding position and completes the positioning; when the feeding position sensor detects "no material" and the discharging position sensor detects "no material", the control system starts a delay program, the delay time can be 0.5s, the accuracy can be ±1ms, and after the delay ends, the rotating assembly performs the overturning action to ensure the stop precision of the material in the feeding position, and finally the pneumatic push rod completes the discharging.

[0071] In this embodiment, the posture adjustment mechanism can match the intermittent feeding rhythm of production on the one hand, and can ensure the double precision of the material posture and position on the other hand.

[0072] In one embodiment, before the material slides to the discharging conveying mechanism, it further includes:

[0073] Obtaining the discharging state of the feeding position by a discharging state sensor;

[0074] When the discharging state sensor detects that the discharging state is a full material state, the full material gate is closed to prevent the material from entering the discharging conveying mechanism;

[0075] When the discharge state sensor detects that the discharge state is a non-full state, the full gate is opened to allow the material to enter the discharge conveying mechanism.

[0076] Specifically, the discharge state sensor can use a diffuse reflection photoelectric sensor installed at the junction of the feeding position and the discharge conveying mechanism for real-time monitoring of the material accumulation state of the feeding position; the driving device of the full gate can use compressed air driving to realize the opening and closing action of the gate with the cooperation of the air cylinder; ideally, the detection response time of the diffuse reflection photoelectric sensor should be less than 2ms to ensure rapid identification of the full state, and the opening and closing action response time of the gate should be less than 0.1s to quickly respond to the sensor signal.

[0077] The detection signal can be transmitted to the corresponding control system and the air cylinder through the I / O interface:

[0078] When the feeding position is accumulated with material due to the downstream equipment not taking material, and the discharge state sensor detects the full state, the discharge state sensor transmits a signal to the control system, which immediately triggers the air cylinder action of the full gate, and the gate is quickly closed within 0.1s to block the channel between the material sorting turntable and the discharge conveying mechanism, preventing the material from continuing to enter the discharge conveying mechanism and causing accumulation overflow.

[0079] When the downstream equipment takes away the material of the feeding position, and the discharge state sensor detects a non-full state, the sensor signal switches, and the control system controls the air cylinder to act in reverse, and the full gate opens within 0.1s to restore the material conveying from the material sorting turntable to the discharge conveying mechanism. At this time, the material sorting turntable can continue to run to ensure the continuity of the material sorting process.

[0080] In this embodiment, the full gate and the discharge state sensor can form a closed-loop control, which can not only avoid the blockage of the discharge conveying mechanism due to full material, but also ensure that the material sorting part does not stop working, thereby improving the overall operation efficiency of the equipment.

[0081] The working process of one embodiment is as follows:

[0082] The operator puts the material into the material supplementing bin, and the specific area of the material sorting turntable is installed with a proximity switch sensor for detecting the amount of material on the turntable. When the amount of material in the sensor sensing range is below the preset threshold, the material supplementing bin will automatically supplement material to the material sorting turntable until the sensor detects that the material is sufficient.

[0083] After starting the equipment, the operator sets the speed of the material sorting turntable through the human-machine interface, and the material sorting turntable starts to rotate under the drive of the driving motor, and the material is pushed from the center to the edge under the action of the rotation of the material sorting turntable.

[0084] When the material moves to a screening mechanism from the sorting disc, the screening mechanism performs Z-direction surface cutting on the material, and pushes back the material with a height exceeding a set value or overlapping to the center of the sorting disc, and the rest of the material continues to move. Then, the material enters a second screening mechanism, the second screening mechanism performs radial screening on the material, and retains the material passing in a minimum size posture in the radial direction, and the material not passing is slid back to the center through the slope surface of the sorting disc;

[0085] The material passing through the second screening mechanism slides to the edge of the sorting disc under the action of the inclined block, so that the material generates a gap in the circumferential direction. Then, the material enters a third screening mechanism, the third screening mechanism performs posture judgment on the material, and the material with OK posture judgment slides to the material output conveying mechanism through the material output block, and the material with NG posture judgment is sent back to the center of the sorting disc through the air blowing electromagnetic valve;

[0086] The material output conveying mechanism conveys the material passing through the third screening mechanism, before the material slides to the material output conveying mechanism, the material output state sensor obtains the material output state of the feeding position, when detecting the full material state, the full material gate is closed to prevent the material from entering, and when detecting the non-full material state, the full material gate is opened to allow the material to enter;

[0087] The posture adjusting mechanism receives the material from the material output conveying mechanism, adjusts the posture of the material according to the production requirement, and controls the stopping repeat accuracy of the material in the feeding position, the posture adjusting mechanism obtains the material state of the feeding position and the material output position through the material state sensor: when the feeding position has material, the mechanism does not act; when the feeding position has no material and the material output position has material, the mechanism flips the material to complete the posture adjustment; when the feeding position has no material and the material output position has no material, the mechanism delays the flipping of the material, controls the stopping repeat accuracy of the material in the feeding position, and then completes the posture adjustment, and outputs the material after the adjustment.

[0088] One of the embodiments of the present application also provides a flexible sorting disc surface treatment and material guiding system based on the foregoing flexible sorting disc surface treatment and material guiding method, comprising:

[0089] A main control unit is used for receiving signals of each module and executing a preset control logic;

[0090] A sensing detection module is used for detecting the material state of the feeding position and the material output position through the material state sensor, so as to transmit a detection signal to the main control unit;

[0091] A material supplementing control module is connected with the material supplementing bin, and is used for detecting the material state of the sorting disc, so as to control the material supplementing bin to supplement the material to the sorting disc according to the material state of the sorting disc;

[0092] A sorting disc driving module is connected with a driving motor, and is used for controlling the rotating speed of the driving motor, so as to control the rotating speed of the sorting disc;

[0093] A screening control module is connected with the first screening mechanism, the second screening mechanism and the third screening mechanism respectively, and is used for controlling respectively:

[0094] Z-direction height and pushing action of the first screening mechanism, so as to control the first screening mechanism to push the material with height exceeding a set value or overlapping back to the center of the material arranging turntable;

[0095] Radial position and screening action of the second screening mechanism, so as to control the second screening mechanism to perform radial screening on the material passing through the first screening mechanism;

[0096] Posture detection of the third screening mechanism and driving of the air blowing electromagnetic valve, so as to control the air blowing electromagnetic valve to make the material return to the center of the material arranging turntable;

[0097] A material discharging conveying control module is connected with the material discharging conveying mechanism, and is used for adjusting and controlling the conveying speed of the material conveyed to the posture adjusting mechanism or the material feeding position.

[0098] It should be noted that the modules in the system are closely coordinated, and the parameter setting and operation control in each module can be set based on multiple factors such as material characteristics, production rhythm and equipment operation state, and the specific setting is as follows:

[0099] Specifically, the main control unit can adopt an industrial-grade PLC (programmable logic controller) with high-speed data processing capability and rich I / O interface, which can quickly receive various signals transmitted by the sensing detection module, accurately output control instructions according to the preset control logic, and coordinate the orderly operation of each module.

[0100] The material state sensor of the sensing detection module is selected as a high-precision photoelectric sensor, which is installed at the key positions of the material feeding position and the material discharging position, and is used for real-time and accurate detection of the presence or absence of the material, and the detection signal is connected to the I / O module of the main control unit through a shielded cable to ensure stable signal transmission.

[0101] The material supplementing control module is installed with a proximity switch sensor near the center area of the material arranging turntable. When it is detected that the amount of material on the material arranging turntable is lower than the threshold value preset according to factors such as material volume, density and production rhythm, a signal is immediately output to the main control unit, and the main control unit immediately controls the vibration device of the material supplementing bin to start, so that the material buffered in the material supplementing bin is smoothly supplemented to the material arranging turntable, thereby maintaining the stability of the amount of material in the material arranging process.

[0102] The material arranging driving module is connected with an AC asynchronous motor through a frequency converter. The operator can directly input a rotating speed instruction on a man-machine interaction interface, and the frequency converter adjusts the frequency of the motor power supply according to the rotating speed instruction to accurately control the rotating speed of the motor, and then drives the material arranging turntable to rotate stably at a set speed.

[0103] The screening control module is connected with a screening mechanism, a second screening mechanism and a third screening mechanism respectively. For the first screening mechanism, the height range can be adjusted by driving the screw nut mechanism through the stepping motor. For the second screening mechanism, the radial position can be adjusted by cooperating the linear guide with the servo motor. For the third screening mechanism, the material posture can be detected by the visual sensor. When the posture is detected as NG, the main control unit triggers the air blowing electromagnetic valve to blow the unqualified material back to the center of the material sorting turntable.

[0104] The discharge conveying control module can adjust the output frequency of the motor according to the speed requirement of the downstream equipment to continuously adjust the conveying speed of the discharge conveying mechanism, so as to ensure that the material is smoothly and continuously conveyed to the posture adjusting mechanism or the feeding position.

[0105] In this embodiment, through the cooperation of each module, the automation degree, material sorting accuracy and production efficiency of the flexible material sorting turntable surface treatment and material guiding system can be effectively improved, the manual intervention can be reduced, and the material loss can be reduced.

[0106] In one embodiment, the posture adjusting control module is also included, which is connected with the posture adjusting mechanism and the material state sensor respectively, and is used for receiving the material state sensor signal of the feeding position and the discharge position. The posture adjusting mechanism is controlled to adjust the posture of the material passing through the discharge conveying mechanism, and the stopping repetition accuracy of the material at the feeding position is controlled.

[0107] It should be noted that the operation logic of the posture adjusting control module is based on the material state feedback of the feeding position and the discharge position. The action accuracy and response speed need to match the overall material sorting rhythm, and specific parameters can be set according to the material size and production requirements.

[0108] Specifically, the posture adjusting control module is connected with the servo motor of the posture adjusting mechanism, the pneumatic push rod, and the photoelectric sensor of the feeding position and the discharge position respectively. The sensor detection signal is transmitted to the module in real time through the I / O interface. The posture adjusting control module has built-in control logic, which can judge the material state according to the signal and output instructions.

[0109] When the feeding position sensor detects "material", the module outputs a stop signal, and the rotating assembly and the pneumatic push rod of the posture adjusting mechanism do not act, so as to avoid material accumulation.

[0110] When the feeding position sensor detects "no material" and the discharge position sensor detects "material", the module immediately sends a turnover instruction to control the servo motor to drive the rotating assembly to complete 90-degree or 180-degree turnover, and then drive the pneumatic push rod to push the material to the feeding position, so as to ensure the repetition accuracy of the material stopping position.

[0111] When the feeding position sensor detects "no material" and the discharging position sensor detects "no material", the module starts a delay program, and after the delay ends, a reversing action is performed, and the positioning accuracy is further optimized through servo motor pulse compensation, and finally the discharging is completed.

[0112] In one embodiment, a full material control module is further included, which is connected with the driving device of the full material gate and the discharging state sensor respectively, and is used for receiving the discharging state sensor signal, detecting the full material state of the feeding position, and controlling the opening and closing action of the full material gate.

[0113] In this embodiment, the posture adjustment control module can ensure the accuracy of the material posture conversion by receiving the sensor signal in real time and dynamically adjusting the mechanism action, and can improve the adaptability of the system to diversified production conditions by matching the gap feeding demand of the downstream equipment through precise stop control and delay logic.

[0114] In one embodiment, a human-computer interaction module configured with a touch screen is further included, which is connected with the main control unit, and is used for receiving the parameter setting input by the user and displaying the equipment running state in real time.

[0115] It should be noted that the human-computer interaction module configured with the touch screen is a direct interaction interface between the operator and the equipment system, and the function implementation and the signal transmission of the main control unit need to be kept real-time;

[0116] Specifically, the touch screen of the human-computer interaction module can adopt an industrial-grade resistive or capacitive touch screen, and is connected with the main control unit through a communication interface (such as RS232 / RS485) to realize bidirectional data transmission; the operator can input various parameter settings through the touch screen, such as the material sorting turntable speed, the Z-direction height of the second screening mechanism, the radial position of the third screening mechanism, the air pressure of the three-screen air blowing electromagnetic valve, the discharging conveying speed, the posture adjustment delay time, etc., and the input parameters are directly acted on the corresponding control module after being verified by the main control unit. At the same time, the touch screen displays the equipment running state in real time, including the running speed of each motor, the detection state of the sensor, the action state of the mechanism and the alarm information, and the state updating frequency is synchronized with the data refreshing frequency of the main control unit.

[0117] In this embodiment, the human-computer interaction module realizes the visual parameter setting and real-time monitoring of the equipment state through the touch screen, simplifies the operation process, and reduces the complexity of manual intervention; the operator does not need to deeply understand the internal logic of the system, and can complete the parameter adjustment and fault troubleshooting through the intuitive interface, thereby improving the ease of use and maintenance efficiency of the equipment, and the accuracy of the parameter setting also guarantees the stability of the collaborative operation of each module.

[0124] The application can continuously provide materials for the sorting process and realize preliminary dispersion of the materials by centrifugal force through the automatic feeding function of the feeding bin and the rotation driving of the sorting turntable, so as to realize the effects of reducing manual intervention and ensuring the continuity of sorting; through the Z-direction surface cutting of the first screening mechanism, the radial screening of the second screening mechanism, the gap separation of the inclined blocking, the posture recognition and air blowing of the third screening mechanism, the effects of gradually and accurately screening from the height, the radial size, the gap to the final posture can be achieved, so as to unify the posture of the materials and avoid the stacking of the materials, and the effects of improving the feeding precision of the materials and reducing the risk of small size material jamming can be realized; through the overturning function of the posture adjusting mechanism, the sensor detection of the feeding position and the discharging position, and the logical control of the main control unit, the posture of the materials can be dynamically adjusted according to the production demand, and the stopping and repeating precision of the materials at the feeding position can be controlled, so as to match the demand of the production link for the posture and gap feeding of the materials, and the effect of flexible adaptation to different working conditions can be realized; through the pneumatic driving of the full material gate, the full material state sensor of the feeding position, and the linkage control of the main control unit, the sorting outlet can be quickly locked when the discharging conveying is full, and the discharging can be restored when it is not full, so as to coordinate the rhythm of sorting and discharging, realize the effect of non-stop operation of the sorting machine, and avoid the accumulation and blockage of the materials; through the cooperation of the core control and sensing detection module, the feeding control module, the screening control module and the like of the main control unit, and the parameter setting of the touch screen of the man-machine interaction module, the whole process automatic control and real-time state monitoring can be realized, so as to simplify the operation of the equipment and support the flexible adjustment of the processing parameters, and the effects of reducing the use threshold of the equipment, improving the adaptability and expansibility of the system can be realized; through the above cooperation, the overall flexibility range of the sorting equipment can be improved, the overall feeding speed of the sorting equipment can be accelerated, and the overall cost of the sorting equipment can be controlled, so as to solve the problems of relatively small flexibility range and relatively slow feeding speed of the existing discrete material automatic scheme;
