Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of beverage production, and relates to a weighing device, in particular to a precise weighing device for ingredient feeding of tremella beverage. BACKGROUND

[0002] In the food industry, especially in the production of high-end tremella beverage, there has been a technical challenge in the accurate and efficient feeding of various solid ingredients. The existing technical solutions mainly have the following shortcomings:

[0003] Firstly, traditional manual weighing or semi-automatic equipment is inefficient and relies on experience, and cannot remove unqualified products online, resulting in poor product consistency and large quality fluctuations. The existing equipment adopts a static mode of "weighing first and then feeding", which is difficult to integrate into a continuous production line.

[0004] Secondly, the existing automatic equipment is usually equipped with only a single type of feeding mechanism (such as vibration feeding), which is difficult to adapt to the characteristics of various materials such as wolfberry, almond, and jujube with different particle sizes, shapes, and degrees of damage, resulting in unstable feeding accuracy or material damage.

[0005] Finally, most systems are open-loop control and do not have self-adaptive and learning capabilities. When the density and humidity of the material batch change, manual adjustment of parameters is required, real-time closed-loop correction is not possible, and long-term stability and intelligent level of production are difficult to guarantee.

[0006] Therefore, we propose a precise weighing device for ingredient feeding of tremella beverage. SUMMARY

[0007] The purpose of the present application is to solve the above-mentioned problems existing in the prior art, and to propose a precise weighing device for ingredient feeding of tremella beverage. The technical problem to be solved by the present application is: how to realize the mechanical and electrical soft integration design, and upgrade the accurate weighing to a complete intelligent system covering "feeding optimization, online verification, automatic sorting, and continuous self-adjustment".

[0008] The purpose of the present application can be realized by the following technical solutions:

[0009] The application relates to a precise weighing device for a tremella beverage ingredient feeding machine, which comprises a main control machine, a loading conveying mechanism, a plurality of granular quantitative feeding mechanisms, a plurality of vibrating quantitative feeding mechanisms and a plurality of turnover quantitative feeding mechanisms, the loading conveying mechanism is provided with a plurality of equally-distributed position adjusting weighing mechanisms on the side, the upper end of the position adjusting weighing mechanism is provided with four circumferentially-distributed weighing feeding mechanisms, the upper end of the position adjusting weighing mechanism is circumferentially divided into a feeding area, a light material area, a feeding area and a heavy material area in sequence, the feeding area is located on the side close to the loading conveying mechanism, the feeding area is located on the side far from the loading conveying mechanism, the four weighing feeding mechanisms are respectively located in the feeding area, the light material area, the feeding area and the heavy material area, the number of the granular quantitative feeding mechanisms, the vibrating quantitative feeding mechanisms and the turnover quantitative feeding mechanisms is the same as that of the position adjusting weighing mechanisms, and the granular quantitative feeding mechanisms, the vibrating quantitative feeding mechanisms and the turnover quantitative feeding mechanisms are respectively located above the weighing feeding mechanisms of the feeding area far from the loading conveying mechanism of the position adjusting weighing mechanisms on the upper end of the corresponding position adjusting weighing mechanisms, the position adjusting weighing mechanisms are provided with discharging conveyors on the two sides, the two discharging conveyors are respectively located below the weighing feeding mechanisms of the light material area and the heavy material area, and the main control board of the main control machine is provided with a weighing module, a verification module, an adjustment module, a data management module, an equipment cooperation module and a man-machine interaction module.

[0010] The working principle of the application is as follows:

[0011] 1. Pre-setting: according to the proportion of each ingredient of the tremella beverage, the weight information is input through the man-machine interaction module and is transmitted to the main control machine.

[0012] 2. Feeding: the material bowl is sequentially placed on the loading conveying mechanism and is sequentially conveyed to the corresponding positions of the position adjusting weighing mechanisms.

[0013] Small-particle-diameter tremella beverage ingredients such as medlar are conveyed into the granular quantitative feeding mechanism, medium-particle-diameter tremella beverage ingredients such as apricot kernels are conveyed into the vibrating quantitative feeding mechanism, and large-particle-diameter tremella beverage ingredients such as jujube are conveyed into the granular quantitative feeding mechanism,

[0014] The granular quantitative feeding mechanism, the vibrating quantitative feeding mechanism and the turnover quantitative feeding mechanism matched with the position adjusting weighing mechanism are started to feed the preset amount of material to the weighing feeding mechanism located in the feeding area.

[0015] 3. Verification and judgment: the material falls into the weighing feeding mechanism, the two sensors on the weighing feeding mechanism cooperate, twice weighing is completed, and the weight is verified by the position adjusting weighing mechanism.

[0016] The weighing information of the weighing feeding mechanism and the position adjusting weighing mechanism is transmitted to the weighing module, the weight is analyzed by the weighing module, the analysis information is transmitted to the verification module, the measured value is compared with the target value by the verification module, and the judgment is immediately made:

[0017] Pass, weight within tolerance. Too light, weight below lower limit. Too heavy, weight above upper limit.

[0018] 4. Shunt execution: the positioning weighing mechanism drives the material-carrying weighing and discharging mechanism to rotate;

[0019] According to the verification result, the equipment coordination module controls the positioning weighing mechanism and the weighing and discharging mechanism to perform different actions:

[0020] Pass: continue to rotate to the "discharging area", the weighing and discharging mechanism is opened, and the qualified material is accurately discharged into the material bowl on the downstream charging conveyor mechanism to complete the filling.

[0021] Too light: stay in the "light material area", the weighing and discharging mechanism is opened, and the unqualified material is discharged into the discharge conveyor on one side, and returned to the upstream process or treated as waste.

[0022] Too heavy: rotate to the "heavy material area", the weighing and discharging mechanism is opened, and the unqualified material is discharged into the discharge conveyor on the other side.

[0023] 5. Intelligent adjustment: when the verification module continuously detects systematic deviation of the material corresponding to a specific discharging mechanism, the adjustment module is started. The adjustment module analyzes the deviation data and automatically or prompts the operator to adjust the material quality of the corresponding discharging mechanism, or adjust the parameters to correct the feeding amount of the next batch of material.

[0024] The main control machine integrates various software modules to coordinate the entire system. The weighing module obtains real-time weight data of each positioning weighing mechanism and weighing and discharging mechanism. The verification module quickly judges the weight state of the material and determines the destination of the material. The adjustment module analyzes historical deviations, optimizes discharging mechanism parameters, and responds to material fluctuations. The data management module records all weighing results, deviations and adjustment records for quality traceability and report analysis. The equipment coordination module accurately controls the start and stop and timing of the conveying mechanism, discharging mechanism, weighing mechanism and discharging mechanism to ensure smooth and error-free action. The human-computer interaction module provides operators with state monitoring, parameter setting, alarm prompts and report query interfaces.

[0025] The charging conveyor mechanism comprises a plurality of conveying positioning support rod seats, the upper ends of the plurality of conveying positioning support rod seats are fixed with mounting seats, the upper ends of the plurality of mounting seats are provided with a conveying frame, the conveying frame is fixed with symmetrically arranged side seats on both sides, the side seats are fixed with adjusting seats, the adjusting seats are fixed with vertically arranged locking screws at the upper ends, the adjusting seats are slidably provided with adjusting struts penetrating through the adjusting seats, the adjusting struts are horizontally arranged, the lower ends of the locking screws abut against the upper ends of the adjusting struts, the end portions of the adjusting struts on the same side are provided with limiting side plates, the inner side of the conveying frame is provided with a conveying chain, the outer side of the conveying frame is fixed with a conveying motor, and the output shaft of the conveying motor is fixedly connected with one of the rotating shafts of the conveying chain.

[0026] With the above structure, the conveying motor is started, and the output shaft drives one of the rotating shafts of the conveying chain to rotate, thereby driving the conveying chain to move. The rotating conveying chain drives the bowls on it to move linearly along the conveying frame, and in turn passes under each positioning and weighing mechanism.

[0027] When different sizes or types of bowls need to be processed, the operator rotates the locking screw at the upper end of the adjusting seat.

[0028] Loosen the locking screw so that its lower end no longer tightly abuts the adjusting support rod. At this time, the adjusting support rod can freely slide horizontally in the through hole of the adjusting seat.

[0029] The operator simultaneously moves the adjusting support rods on both sides of the conveying frame, driving the limiting side plates fixed to the ends of the adjusting support rods to move inward or outward, thereby changing the width of the passage between the two limiting side plates to match the width of the bowl.

[0030] After adjusting to the appropriate width, tighten the locking screws on both sides again. The lower end of the screw tightly presses against the adjusting support rod, and the friction force firmly fixes the adjusting support rod in the adjusting seat, completing the rigid locking of the entire width adjustment mechanism.

[0031] During equipment operation, the two limiting side plates of the locked width form an accurate conveying passage. This ensures that each bowl does not deviate or swing laterally during conveying and always accurately aligns with the center of the work position of the positioning and weighing mechanism below its movement trajectory, providing a position reference for the accurate placement and weighing of subsequent materials.

[0032] The positioning and weighing mechanism comprises a positioning frame, four pressure sensors one are fixed to the lower end of the positioning frame, a cam divider, a positioning laser sensor and a plurality of circumferentially distributed support seats are fixed to the upper end of the positioning frame, the cam divider is located in the middle of the upper end of the positioning frame, the plurality of support seats are circumferentially distributed around the cam divider, the positioning laser sensor is located outside the support seats, a cam motor is fixed to the lower end of the positioning frame, the output shaft of the cam motor is in transmission connection with the input shaft of the cam divider, a rotating disc is fixed to the output shaft of the cam divider, an adjusting rod is adjustably arranged at the upper end of each support seat, a wheel seat is fixed to the upper end of each adjusting rod, a support wheel is rotatably arranged at the upper end of each wheel seat, and the support wheels roll against the lower end face of the rotating disc. The feeding area, the light material area, the discharging area and the heavy material area are arranged on the upper end face of the rotating disc.

[0033] With the above structure, the initial state and the load: the weighing and discharging mechanism is placed on the designated area of the rotating disc. The weight of the material is transmitted to the bottom positioning frame through the rotating disc and the support structure, and is sensed by the four pressure sensors one for weight verification.

[0034] Command-driven and precise positioning: When the material needs to be transferred to the next station, the device coordination module issues a command. The cam motor starts, driving the cam divider. The cam divider converts the continuous rotation of the cam motor into accurate intermittent rotation of the output shaft. The rotating disc drives the weighing and dosing mechanism on it, rotates smoothly, and accurately aligns with the next target station. The positioning laser sensor can be used to detect the reference position of the rotating disc or to assist in verifying the number of rotations / angles, ensuring the accuracy of the positioning.

[0035] Stable support and accurate weighing: The support wheels roll with the rotating disc when it rotates, reducing friction; after the rotating disc is stationary and positioned, the support wheel system bears most of the structural weight, creating a stable measurement environment for the pressure sensor, avoiding mechanical stress interference, and thus obtaining high-precision "verification weighing" data. The design of the adjustment rod allows fine-tuning of the height of each support wheel, ensuring that the rotating disc is absolutely flat on the horizontal plane, which is crucial to ensure the accuracy of the weighing and the smoothness of the rotation.

[0036] The weighing and dosing mechanism includes a fixed ring, the lower end of which is fixed with three circumferentially distributed weighing and dosing frame rods, the lower end of each weighing and dosing frame rod is provided with a pressure sensor two, the pressure sensor two is arranged on the upper end surface of the rotating disc, a reinforcing hole plate is fixed between the lower half of the three weighing and dosing frame rods, the lower end of the fixed ring is provided with three circumferentially distributed weighing sensors, the positions of the weighing sensors correspond to the positions of the weighing and dosing frame rods, the weighing sensors are located on the inner side of the weighing and dosing frame rods at the same position, the lower end of each weighing sensor is connected with a side connecting rod, the inner side of the three side connecting rods is fixed with a dosing cone, the upper end surface of the dosing cone is higher than the upper end surface of the fixed ring, the lower end of the dosing cone is provided with a turnover unloading valve, the lower end of the turnover unloading valve is connected with a guide hopper, the guide hopper penetrates the reinforcing hole plate, the lower end of the guide hopper is provided with a horizontally arranged guide pipe, the inner side end of the guide pipe is provided with an air inlet valve in communication therewith, the air inlet valve is connected with an air pump through a pipeline, the outer side end of the guide pipe is connected with a discharge pipe, and the discharge pipe extends out of the rotating disc.

[0037] With the above structure, the material falls into the dosing cone from the upper particle quantitative dosing mechanism, the vibrating quantitative discharge mechanism and the turnover quantitative discharge mechanism. The weighing sensor immediately measures the net weight of the material, and this data is sent to the weighing module together with the total weight data measured by the pressure sensor two for rapid analysis and preliminary judgment.

[0038] Rotation verification and secondary weighing: The entire mechanism rotates with the rotating disc to the "light material area". In a stationary and stable state, the weighing sensor performs high-precision "verification weighing" again. At this time, the data of the pressure sensor two is used to compensate and verify the stability of the mechanism. The verification module makes a final decision of "qualified, too light, too heavy" based on the final accurate weight data.

[0039] Judgment execution and directional discharge: according to the judgment result, the rotating disc rotates the mechanism to the corresponding station. The device coordination module issues an instruction to open the reverse discharge valve. The material falls through the discharge cone, the guide hopper, and into the guide pipe. The air valve opens to provide compressed air from the air pump at high speed into the guide pipe. The material is accurately discharged from the discharge pipe.

[0040] Emptying and cleaning: after the material is discharged, the reverse discharge valve is closed.

[0041] The granular quantitative feeding mechanism includes a fixed seat, an adjustable electric push rod detachably arranged at the upper end of the fixed seat, and an L-shaped discharge disc. A plurality of quantitative feeding holes are formed in the middle of the discharge disc. A stirring ring seat is fixed to the extension end of the adjustable electric push rod. The stirring ring seat is square ring-shaped and is slidingly arranged on the upper end surface of the discharge disc. The length of the upper end surface of the discharge disc is greater than twice the length of the stirring ring seat plus the maximum distance of the plurality of quantitative feeding holes. A flexible hopper in the shape of a square truncated cone with a large upper end and a small lower end is arranged at the upper end of the stirring ring seat.

[0042] With the above structure, the operator sets the required material weight through the human-computer interaction module. The device coordination module finds the corresponding quantitative feeding hole from the calibrated database according to the weight. The module controls the adjustable electric push rod to accurately extend and retract, pushes the stirring ring seat to slide on the discharge disc, and stops until the center of the square hole of the stirring ring seat is completely aligned with the center of the target quantitative feeding hole. At this time, the inner frame of the stirring ring seat covers and uniquely opens the target hole, and the other holes are closed by the seat. The small granular material in the flexible hopper flows downward under the action of gravity. Since the stirring ring seat uniquely opens the pre-set quantitative feeding hole, the material can only fall through this hole. After the material fills the entire volume of the hole, the excess material is blocked by the seat of the stirring ring seat. When the weighing and feeding mechanism is in place, the entire volume of material in the hole falls into the container below by gravity. Once the feeding action is completed, the adjustable electric push rod can be reset or remain in position to prepare for the next feeding of the same weight. When the feeding weight needs to be changed, the adjustable electric push rod is actuated again to move the stirring ring seat to align with another quantitative feeding hole of a different volume, and a new pre-set weight is output.

[0043] The vibrating quantitative feeding mechanism includes a vibrating disc, a discharge ring groove arranged at the upper end of the vibrating disc, a discharge chute connected to the discharge ring groove, and a limiting material electric push rod arranged at the side of the discharge chute. The extension end of the limiting material electric push rod penetrates into the interior of the discharge chute.

[0044] With the above structure, preparation and sequencing: the vibrating disc is started to generate micro-vibration of a specific frequency and amplitude. The material in the disc climbs upward along the spiral track in the disc under the action of vibration, and automatically arranges in a single layer, adjusts the direction, forms a continuous and orderly single column, and enters the discharge ring groove in sequence.

[0045] Uniform feeding: orderly material flow from the discharge ring groove into the discharge chute. At this time, the telescopic end of the limiting electric push rod is in the "retracted" state, and the material can pass through the end of the chute without obstruction, and fall freely into the weighing and discharging mechanism below.

[0046] Dynamic quantification and stopping: after the feeding starts, the system starts timing. When the feeding time calculated according to the preset weight and the pre-calibrated material flow rate is reached, the module immediately sends an instruction to the limiting electric push rod. The telescopic end of the electric push rod quickly extends forward and directly inserts and blocks the passage of the discharge chute, instantly cutting off the falling material flow. After being stopped, the subsequent material is blocked behind the telescopic end, and a small amount of material that has passed through the telescopic end but is still in the air falls into the weighing hopper, completing the quantitative feeding this time.

[0047] Reset standby: after one feeding is completed, the limiting electric push rod retracts, and the gate reopens, ready for the next feeding.

[0048] The turnover quantitative discharging mechanism includes a control box, a laser counter fixed outside the control box, a discharging inclined disc, a support and a guide inclined hopper, which are sequentially inclined from bottom to top, the discharging inclined disc and the guide inclined hopper are fixed on both sides of the upper end of the support, the upper end faces of the discharging inclined disc and the guide inclined hopper are coplanar, a semicircular cavity groove is formed in the middle of the upper end of the support, a fixed frame, a turnover motor and a counting machine are fixed in the control box, a turnover shaft is rotatably arranged on the fixed frame, the outer end of the turnover shaft extends out of the control box, and a turnover discharging cylinder is fixed to the outer end of the turnover shaft, a plurality of circumferentially distributed material clamping holes are formed in the cylinder wall of the turnover discharging cylinder, the outer side end face of the turnover discharging cylinder is open, the turnover discharging cylinder is located in the semicircular cavity groove, the laser counter is located above the turnover discharging cylinder, a material stirring planetary frame is fixed to the inner end of the turnover shaft, a material stirring rod is fixed to the output shaft of the turnover motor, and the material stirring rod is in driving engagement with the material stirring planetary frame.

[0049] With the above structure, preparation and grabbing: materials such as jujube slide continuously and in a single layer to the side wall of the turnover discharging cylinder through the guide inclined hopper. The turnover motor is started to drive the turnover discharging cylinder to rotate slowly. When the material clamping hole on the cylinder wall rotates to below the outlet of the guide inclined hopper, a material will fall into and stay in the hole, and be "caught". The laser counter scans each passing material clamping hole in real time. When detecting that there is material in the hole, count once; if an empty hole is detected, the system will record that the hole has not successfully loaded.

[0050] Counting verification: the roller continues to rotate for one or several weeks until all the preset material clamping holes are filled, or according to the preset required number of materials, when the value of the laser counter reaches the target, the grabbing stage stops. This process ensures that each batch of materials is accurate in quantity, which is the prerequisite for weight accuracy.

[0051] Turnover unloading: after the filling and counting verification is completed, the device cooperates with the module to issue an unloading instruction. The output shaft of the turnover motor drives the stirring rod to rotate, drives the stirring planetary gear to rotate, thereby driving the turnover shaft to rotate, and the turnover shaft drives the turnover discharge cylinder to rotate rapidly. During the turnover process, the material in the material clamping hole at the bottom of the cylinder is turned to the upper side. Since one end of the cylinder body is open, all the materials are dumped out in one go and in a whole body under the action of gravity. The dumped materials fall on the discharge inclined disc and slide along the inclined surface into the weighing and discharging mechanism below.

[0052] Reset: after the unloading is completed, the turnover discharge cylinder continues to turn back to the original position, preparing to start the next cycle of grabbing.

[0053] The weighing module includes a data acquisition unit, a data processing unit and a weighing control unit; the verification module includes a standard value management unit, a real-time comparison unit, a decision logic unit and an SPC statistical unit; the adjustment module includes a deviation analysis unit, a parameter optimization unit, a self-adaptive learning unit and an adjustment execution unit; the data management module includes a real-time database unit, a historical data archiving unit, a traceability management unit and a report generation unit; the device cooperation module includes a timing control unit, a state monitoring unit, a communication management unit and an exception handling unit; the human-computer interaction module includes a user interface unit, a formula management unit, an alarm display unit, a remote access unit and a training and help unit.

[0054] Compared with the prior art, the tremella drink ingredient feeding and precise weighing device has the following advantages:

[0055] The application adopts a closed-loop sorting mechanism of "rotary verification and physical partitioning", accurately rotates the weighing unit among the four stations through a cam divider, converts the weight decision into a physical position, realizes online, automatic and lossless rejection of unqualified products, and ensures the weight qualified rate of the output materials.

[0056] The application constructs a complete "perception-decision-execution-optimization" data intelligent closed loop. The six software modules work cooperatively, not only can control in real time, but also can analyze historical data through the adjustment module, self-learn and reversely optimize the feeding parameters, so that the device can actively adapt to material fluctuations, and upgrade from an automatic machine to an intelligent production unit.

[0057] The application realizes flexible and high-precision production. According to different material characteristics, three kinds of quantitative mechanisms of particles, vibration and turnover are integrated to optimize the feeding strategy from the source. Through redundant weighing verification and pneumatic cleaning design, the comprehensive precision, long-term stability and production efficiency are finally ensured. BRIEF DESCRIPTION OF DRAWINGS

[0087] The conveying motor 16 is started, the output shaft of the conveying motor 16 drives one rotating shaft of the conveying chains 10 to rotate, so as to drive the conveying chains 10 to move. The rotating conveying chains 10 drive the material bowls 2 thereon to move linearly along the conveying frames, and sequentially pass below the position adjusting weighing mechanisms 3. When it is required to process material bowls of different sizes or models, the operator rotates the locking screws 13 at the upper ends of the adjusting seats 12. The locking screws 13 are loosened, so that the lower ends of the locking screws 13 no longer abut against the adjusting support rods 14. At this time, the adjusting support rods 14 can freely slide horizontally in the penetrating holes of the adjusting seats 12. The operator simultaneously moves the adjusting support rods 14 on the two sides of the conveying frames, drives the limiting side plates 15 fixed to the end portions of the adjusting support rods 14 to move inwardly or outwardly, so as to change the width of the passage between the two limiting side plates 15, and match the width of the material bowls 2. After the width is adjusted to be appropriate, the locking screws 13 on the two sides are re-tightened. The lower ends of the locking screws 13 downwardly abut against the adjusting support rods 14, and the adjusting support rods 14 are fixedly arranged in the adjusting seats 12 by the frictional force, so that the rigidity locking of the whole width adjusting mechanism is completed. During the operation of the equipment, the two limiting side plates 15 of the locked width constitute an accurate conveying passage. It is ensured that each material bowl 2 does not deviate or swing in the conveying process, and is always accurately aligned with the center of the position of the position adjusting weighing mechanism 3 below the movement track, so as to provide a position reference for the accurate feeding and weighing of the subsequent material.

[0088] The position adjusting and weighing mechanism 3 comprises a position adjusting frame 18, the lower end of the position adjusting frame 18 is fixed with four pressure sensors 17, the upper end of the position adjusting frame 18 is fixed with a cam divider 24, a position adjusting laser sensor 19 and a plurality of circumferentially distributed support seats 20, the cam divider 24 is located at the middle of the upper end of the position adjusting frame 18, the plurality of support seats 20 are circumferentially distributed around the cam divider 24, the position adjusting laser sensor 19 is located outside the support seats 20, the lower end of the position adjusting frame 18 is fixed with a cam motor 26, the output shaft of the cam motor 26 is in transmission connection with the input shaft of the cam divider 24, the output shaft of the cam divider 24 is fixed with a rotating disc 25, the upper end of each support seat 20 is adjustably provided with an adjusting rod 21, the upper end of each adjusting rod 21 is fixed with a wheel seat 23, the upper end of each wheel seat 23 is rotatably provided with a support wheel 22, the support wheels 22 are all in rolling abutment against the lower end face of the rotating disc 25, the feeding area, the light material area, the discharging area and the heavy material area are arranged on the upper end face of the rotating disc 25.

[0089] The weighing and discharging mechanism 4 carries the material, and is accurately rotated to one of the four predetermined stations of “feeding, light material, discharging and heavy material” according to the instruction, and provides accurate weight data.

[0090] The weighing system is composed of the four pressure sensors 17 at the bottom, and is used for sensing the total weight change of the whole mechanism (including the rotating disc 25, the material thereon and the weighing and discharging mechanism 4).

[0091] The rotating driving and indexing system is composed of the cam motor 26 driving the cam divider 24 to drive the rotating disc 25 to make accurate intermittent rotation (90° each time).

[0092] The stable support system is composed of the support seats 20, the adjusting rods 21, the wheel seats 23 and the support wheels 22, and is used for providing stable and adjustable auxiliary support for the rotating disc 25 when it rotates or is static, and ensuring the weighing stability.

[0093] Initial state and carrying:

[0094] The weighing and discharging mechanism 4 (containing the material to be measured) is arranged on the specified area (such as the feeding area) of the rotating disc 25.

[0095] The weight of the material is finally transmitted to the bottom position adjusting frame 18 through the rotating disc 25 and the support structure, and is sensed by the four pressure sensors 17 to verify the weight.

[0096] Instruction driving and accurate positioning: when it is needed to move the material to the next station (such as from the “feeding area” to the “light material area”), the device cooperates with the module to issue an instruction.

[0097] The cam motor 26 is started to drive the cam divider 24. The cam divider 24 converts the continuous rotation of the cam motor 26 into accurate intermittent rotation of the output shaft (i.e. the rotating disc 25).

[0098] The rotating disc 25 drives the weighing and discharging mechanism 4 on it to rotate 90 degrees stably and accurately to align with the next target work station (such as the discharge port of the light material area or above the material bowl of the discharging area).

[0099] The positioning laser sensor 19 can be used to detect the reference position of the rotating disc or to assist in verifying the number of rotations / angles, ensuring the accuracy of positioning.

[0100] Stable support and accurate weighing: the support wheels 22 roll with the rotating disc 25 to reduce friction; after the rotating disc 25 is positioned, the support wheel system bears most of the structural weight, creating a stable measurement environment for the pressure sensor 17, avoiding mechanical stress interference, and obtaining high-precision "verification weighing" data. The design of the adjusting rod 21 allows fine-tuning the height of each support wheel 22, ensuring that the rotating disc 25 is absolutely flat on the horizontal plane, which is the key to ensuring the accuracy of weighing and the smoothness of rotation.

[0101] The weighing and discharging mechanism 4 includes a fixed ring 29, the lower end of which is fixed with three circumferentially distributed weighing and discharging frame rods 28, the lower end of each of which is provided with a pressure sensor 27, which is arranged on the upper end surface of the rotating disc 25. The lower half of the three weighing and discharging frame rods 28 is fixed with a reinforcing hole plate 36, and the lower end of the fixed ring 29 is provided with three circumferentially distributed weighing sensors 30, which correspond to the positions of the weighing and discharging frame rods 28. The weighing sensors 30 are located on the inner side of the weighing and discharging frame rods 28 at the same position. The lower end of each weighing sensor 30 is connected with a side connecting rod 31, and the inner side of the three side connecting rods 31 is fixed with a discharging cone 32, the upper end surface of which is higher than the upper end surface of the fixed ring 29. The lower end of the discharging cone 32 is provided with a turnover discharge valve 34, the lower end of which is connected with a guide hopper 35, which penetrates the reinforcing hole plate 36. The lower end of the guide hopper 35 is provided with a horizontally arranged guide pipe, the inner side end of which is provided with a gas inlet valve 33 connected therewith. The gas inlet valve 33 is connected with an air pump through a pipeline, and the outer side end of the guide pipe is connected with a discharge pipe 37, the distal end of which extends out of the rotating disc 25.

[0102] Double-redundancy weighing system: static reference weighing, three pressure sensors two 27, support the entire mechanism sitting on the rotating disc 25, mainly measure the "tare weight" (i.e. the weight when empty) of the measuring mechanism, as the static reference point of the entire weighing system. Dynamic material net weight weighing, three weighing sensors 30 hanging the discharge cone 32. When the material falls into the discharge cone 32, its weight is directly sensed by the three sensors, measuring the net weight of the material. This design, combined with the bottom sensor, can achieve high-precision, anti-interference net weight measurement.

[0103] Feeding and initial weighing: the material falls into the discharge cone 32 from the upper particle quantitative feeding mechanism 5, the vibrating quantitative discharge mechanism 6 and the turnover quantitative discharge mechanism 7. The weighing sensor 30 immediately measures the net weight of the material, and this data (net weight) is sent to the weighing module together with the total weight data measured by the pressure sensor two 27 for rapid analysis and preliminary judgment.

[0104] Rotation verification and secondary weighing: the entire mechanism rotates to the "light material area" with the rotating disc 25. In a stable state, the weighing sensor 30 performs high-precision "verification weighing" again. At this time, the data of the pressure sensor two 27 is used to compensate and verify the stability of the mechanism, that is, the pressure sensor two 27 and the weighing sensor 30 cooperate to complete two weighings. The verification module makes a final decision of "qualified, too light, too heavy" according to the final accurate weight data.

[0105] Decision execution and directional discharge: according to the decision result, the rotating disc rotates the mechanism to the corresponding station (qualified → discharge area; too light → light material area; too heavy → heavy material area). The equipment coordination module issues an instruction to open the turnover discharge valve 34. The material falls into the guide pipe through the discharge cone 32 and the guide hopper 35, and the air valve 33 opens the compressed air provided by the air pump to blow into the guide pipe at high speed, and the material is accurately discharged from the discharge pipe 37. After the material is discharged, the turnover discharge valve 34 is closed.

[0106] The particle quantitative feeding mechanism 5 includes a fixed seat 38, an adjustable electric push rod 43 and an L-shaped discharge disc 39 are detachably arranged at the upper end of the fixed seat 38, a plurality of quantitative feeding holes 40 are formed in the upper middle part of the discharge disc 39, a stirring ring seat 41 is fixed to the extension end of the adjustable electric push rod 43, the stirring ring seat 41 is a square ring, the stirring ring seat 41 is slidingly arranged on the upper end surface of the discharge disc 39, the length of the upper end surface of the discharge disc 39 is greater than twice the length of the stirring ring seat 41 plus the maximum distance of the plurality of quantitative feeding holes 40, and a flexible hopper 42 in the shape of a square truncated cone with a large upper end and a small lower end is arranged at the upper end of the stirring ring seat 41.

[0107] The operator sets the desired material weight (e.g., 8 grams of goji berries) via the human-machine interface module. Based on this weight, the equipment coordination module retrieves the corresponding quantitative feeding hole 40 (e.g., calibrated for 8 grams) from a pre-defined database. The module then controls the precise extension and retraction of the electric push rod 43, pushing the feeding ring seat 41 to slide on the unloading tray until the center of the square inner hole of the feeding ring seat is perfectly aligned with the center of the target quantitative feeding hole. At this point, the inner frame of the feeding ring seat 41 covers and exclusively opens the target hole, while all other holes are closed by their base.

[0108] Small particles in the flexible hopper 42 flow downwards under gravity. Since the feeding ring seat 41 only opens the preset quantitative feeding hole 40, the material can only fall through this hole. After the material fills the entire volume of the hole, excess material is blocked by the feeding ring seat base. When the weighing and feeding mechanism 4 is in place, the entire fixed volume of material in the hole falls into the container below by gravity. Once one feeding action is completed, the adjusting electric push rod 43 can reset or maintain its position to prepare for the next feeding of the same weight.

[0109] When it is necessary to change the feeding weight (such as changing the product formula), adjust the electric push rod 43 to move the feeding ring seat 41 to align with another quantitative feeding hole 40 of different volume, and a new preset weight can be output.

[0110] The vibrating quantitative discharge mechanism 6 includes a vibrating plate 44. The upper end of the vibrating plate 44 is provided with a discharge ring groove 45. The discharge end of the discharge ring groove 45 is connected to a discharge inclined groove 46. The side of the discharge inclined groove 46 is provided with a limiting electric push rod 47. The telescopic end of the limiting electric push rod 47 extends through into the interior of the discharge inclined groove 46.

[0111] Preparation and sorting: The vibratory feeder 44 is started, generating micro-vibrations of a specific frequency and amplitude. Under the action of vibration, the material (such as almonds) in the feeder climbs upward along the spiral track inside the feeder, and automatically arranges itself in a single layer and adjusts its direction during the process, forming a continuous and orderly single-line formation, which then enters the discharge ring trough 45 in sequence.

[0112] Uniform feeding: An orderly flow of material flows from the discharge ring trough 45 into the discharge chute 46. At this time, the telescopic end of the limiting electric push rod 47 is in the "retracted" state, and the material can pass through the end of the chute without obstruction and fall freely into the weighing and feeding mechanism 4 below.

[0113] Dynamic quantification and stopping: After the feeding starts, the system (device coordination module) starts timing. When the feeding time calculated according to the preset weight and the pre-calibrated material flow rate is reached, the module immediately issues an instruction to the material limiting electric push rod 47. The telescopic end of the electric push rod quickly extends forward, directly inserts and blocks the channel of the discharge chute 46, and instantly cuts off the falling material flow. After being stopped, the subsequent material is blocked behind the telescopic end, and a small amount of material that has passed through the telescopic end but is still in the air falls into the weighing hopper, completing the current quantitative feeding.

[0114] Reset standby: After one feeding is completed, the material limiting electric push rod 47 is retracted, and the gate is reopened, ready for the next feeding.

[0115] The turnover quantitative discharging mechanism 7 includes a control box 52, a laser counter 54 fixed on the outer side of the control box 52, a discharge inclined disc 48, a support 49, and a guide inclined hopper 51. The discharge inclined disc 48, the support 49, and the guide inclined hopper 51 are sequentially inclined from bottom to top. The discharge inclined disc 48 and the guide inclined hopper 51 are fixed on the upper ends of the two sides of the support 49, and the upper end faces of the discharge inclined disc 48 and the guide inclined hopper 51 are coplanar. A semicircular cavity groove is formed in the middle of the upper end of the support 49. A fixed frame 53, a turnover motor 55, and a counting machine 57 are fixed in the interior of the control box 52. A turnover shaft 56 is rotatably arranged on the fixed frame 53. The outer end of the turnover shaft 56 extends out of the control box 52, and a turnover discharging cylinder 50 is fixed on the outer end of the turnover shaft 56. A plurality of circumferentially distributed material clamping holes are formed in the cylinder wall of the turnover discharging cylinder 50. The outer side end face of the turnover discharging cylinder 50 is open. The turnover discharging cylinder 50 is located in the semicircular cavity groove. The laser counter 54 is located above the turnover discharging cylinder 50. A material stirring planetary frame 58 is fixed on the inner end of the turnover shaft 56. A material stirring rod 59 is fixed on the output shaft of the turnover motor 55. The material stirring rod 59 is in driving cooperation with the material stirring planetary frame 58.

[0116] Preparation and grabbing (filling stage): The materials such as jujubes continuously and single-layered slide to the side wall of the turnover discharging cylinder 50 through the guide inclined hopper 51. The turnover motor 55 is started to drive the turnover discharging cylinder 50 to rotate slowly. When the material clamping hole on the cylinder wall rotates to the position below the outlet of the guide inclined hopper, a material will fall into and stay in the hole, being “caught”. The laser counter 54 scans each passing material clamping hole in real time. When detecting that there is material in the hole, the counting is once; if an empty hole is detected, the system will record that the hole is not successfully filled.

[0117] Counting verification (ensuring quantitative): The roller continues to rotate for one or several weeks until all the preset material clamping holes are filled, or according to the preset required number of materials, when the value of the laser counter 54 reaches the target, the grabbing stage stops. This process ensures that each batch of materials is accurate in quantity, which is the prerequisite for weight accuracy.

[0118] Tipping and unloading (delivery phase): after the filling and counting verification is completed, the device coordination module issues an unloading instruction. The output shaft of the tipping motor 55 drives the stirring rod 59 to rotate, driving the stirring planetary carrier 58 to rotate, thereby driving the tipping shaft 56 to rotate, and the tipping shaft 56 drives the tipping discharge cylinder 50 to quickly tip. During the tipping process, the material in the material clamping hole at the bottom of the cylinder is turned to the top. Since one end of the cylinder body is open, all the material is dumped out of the open end in one piece under the action of gravity. The dumped material falls on the discharge inclined plate 48 and slides along the inclined surface into the weighing and unloading mechanism 4 below.

[0119] Reset: after unloading is completed, the tipping discharge cylinder 50 continues to tip back to the original position, preparing to start the next cycle of grabbing.

[0145] Working principle of the invention:

[0146] Phase 1: Initialization and Preset (System Preparation)

[0147] Recipe Loading: Operators select or create product recipes through the graphical interface of the Human-Machine Interface (HMI). The recipe not only includes the target weight of each ingredient such as goji berries, almonds, and dates, but more importantly, it includes:

[0148] Tolerance range: Allowable upper and lower deviations (e.g., ±0.5g).

[0149] Control parameters: Pre-calibrated feeding parameters that match the current material batch (such as feed hole number, vibrating feed time, and number of items gripped by the tilting drum).

[0150] Correlation: The correspondence between the formula and the specific workstations of the production line, and the unloading mechanism.

[0151] Parameter issuance: The host computer decomposes and issues formula parameters to corresponding modules. The device coordination module presets the execution parameters of the granular quantitative unloading mechanism 5, the vibrating quantitative unloading mechanism 6, and the turnover quantitative unloading mechanism 7 according to the formula; the weighing module and the verification module load the target value and the tolerance, and prepare for verification.

[0152] Second stage: Synchronous feeding and initial weighing (process start)

[0153] Container positioning: The loading conveying mechanism 1 starts, and the material bowl 2 accurately advances in the adjustable-width guide channel. When the material bowl reaches directly below the first adjustable-position weighing mechanism 3, the conveying belt pauses or synchronizes with the weighing beat.

[0154] Parallel feeding: The system simultaneously (or with a very small time difference) triggers the three unloading mechanisms of the corresponding workstations according to the formula:

[0155] Granular mechanism (goji berries): The adjustable electric push rod 43 has been positioned in advance, so that the only opening of the material stirring ring seat 41 is aligned with the preset weight quantitative unloading hole 40. After the material fills the hole volume by gravity, it falls down.

[0156] Vibrating mechanism (almonds): The vibrating disc 44 continuously works, and the material is orderly arranged. The material limiting electric push rod 47 remains retracted (the channel is open). According to the target weight and the calibrated flow, the system calculates the theoretical feeding time T. When time T arrives, the material limiting electric push rod 47 is instantly extended to cut off the material flow.

[0157] Turnover mechanism (jujubes): The turnover unloading cylinder 50 has completed filling and laser counter 54 verification in the previous cycle, ensuring the accuracy of the number of materials in the cylinder. After receiving the instruction, the turnover motor 55 drives the cylinder to quickly turn 180 degrees, dumping the entire portion of material.

[0158] Initial data fusion: All materials converge into the unloading cone cylinder 32 of the weighing unloading mechanism 4. At this time:

[0159] The weighing sensor 30 of the suspended cone immediately measures the preliminary value M1 of the net weight of the material.

[0160] The pressure sensor two 27 supporting the entire weighing unloading mechanism 4 measures the total value including the self-weight of the mechanism.

[0161] The data processing unit of the weighing module runs in real time: net weight = weighing sensor 30 reading - zero point calibration value; self-weight verification = pressure sensor two 27 reading - weighing sensor 30 reading - known self-weight of the mechanism. This step is used for cross-checking to prevent single sensor failure. The preliminary weight M1 and the status flag are sent to the verification module for preliminary analysis.

[0162] Third stage: rotation verification and final decision (quality decision)

[0163] Rotation positioning: the device coordination module instructs the positioning scale mechanism 3 to start the cam motor 26. The cam divider 24 drives the rotating disc 25, which drives the scale feeding mechanism 4 on it to rotate 90 degrees precisely from the "feeding area" to the "light material area". The cam divider ensures the rigid accuracy of mechanical positioning, and the positioning laser sensor 19 provides position feedback to realize closed-loop control.

[0164] Stabilization and accurate weighing: after rotation stops, the support wheel 22 system bears most of the mechanical structure weight, providing a stable measurement environment without stress interference for the bottom pressure sensor 17. The system waits for a preset stabilization time (such as 200 ms), and waits for the weight reading to be completely stable.

[0165] Double-verification weighing:

[0166] Main verification: the weighing sensor 30 of the scale feeding mechanism 4 itself performs high-precision sampling in a static state to obtain the final net weight value M2. The weighing sensor 30 and the pressure sensor 17 cooperate to perform two weighings.

[0167] Auxiliary verification: the pressure sensor 17 of the positioning scale mechanism 3 reads the total weight including the rotating table, the scale mechanism, and the material, and calculates the material weight M2' by subtracting the calibrated system tare weight, which is used to review M2.

[0168] Intelligent decision: the decision logic unit of the verification module receives M2 and M2'.

[0169] Data reliability check: first, determine whether the difference between M2 and M2' is within a reasonable range. If it exceeds, it is determined that the sensor is abnormal, triggering an alarm and entering the abnormal handling process.

[0170] Eligibility decision: if the data is reliable, compare M2 with the target value T.

[0171] If |M2-T|≤ allowable error, the decision is "qualified".

[0172] If M2-T<-allowable error, the decision is "too light".

[0173] If M2-T>+allowable error, the decision is "too heavy".

[0174] Trend recording: the result (including weight value, deviation value, decision) is sent to the data management module in real time for storage and used by the SPC statistical unit to update the control chart.

[0175] Fourth stage: decision execution and physical diversion (action execution)

[0176] Path selection and rotation: the equipment coordination module issues a second rotation command based on the decision result.

[0177] Decision: "qualified": the cam motor drives the rotating disc to rotate another 90 degrees to the "discharging area". At this time, the discharge pipe 37 outlet of the weighing and discharging mechanism 4 is exactly aligned with the material bowl 2 on the lower conveying belt.

[0178] Decision: "too light": the rotating disc remains stopped at the "light material area". The discharge pipe 37 outlet is aligned with the left discharge conveyor.

[0179] Decision: "too heavy": the rotating disc rotates another 90 degrees (i.e. from the light material area to the "heavy material area"). The discharge pipe 37 outlet is aligned with the right discharge conveyor.

[0180] After positioning is completed, the equipment coordination module triggers the flip discharge valve 34 to open.

[0181] The material enters the guide pipe through the guide hopper 35. At the same time, the air valve 33 is opened for an instant, and compressed air is injected to form a pneumatic push, ensuring that the material is completely and quickly blown out of the discharge pipe 37 without residue.

[0182] After discharging is completed, the valve is closed, and the mechanism is ready for the next cycle.

[0183] Fifth stage: data closed loop and adaptive optimization (system evolution)

[0184] Data aggregation: the data management module records all data of this cycle: parameters of each weighing and discharging mechanism, initial weight M1, final weight M2, decision result, timestamp, station number, etc.

[0185] Continuous monitoring: the SPC statistical unit of the verification module analyzes the weight data of consecutive products in real time. It not only focuses on whether a single product is qualified, but also focuses on the stability of the process:

[0186] Calculate the mean (X) and range (R) of the process.

[0187] Identify abnormal patterns: such as 7 consecutive points deviating to one side of the target value (indicating systematic deviation); consecutive increase or decrease (indicating parameter drift); single point exceeding control limit (random anomaly).

[0188] Intelligent adjustment: when the deviation analysis unit of the adjustment module identifies a systematic deviation pattern (for example, the granular mechanism of station No. 3 has been consistently 1% lighter for 10 consecutive times), it starts:

[0189] Root cause analysis: combined with the material batch information, it is determined whether it is a change in material properties (such as a change in the moisture content of wolfberry leading to a change in density) or a drift in device performance.

[0190] Parameter optimization: the parameter optimization unit starts the algorithm. For example, for the granular mechanism, a new feed hole compensation coefficient is calculated; for the vibration mechanism, the "weight-time" curve is recalibrated, and the feeding time AT is fine-tuned; for the turnover mechanism, the number of grabs is suggested to be adjusted.

[0191] Execution and verification: the adjustment execution unit safely issues new parameters to the corresponding feeding mechanism. The system monitors the weighing results of the subsequent several cycles to verify the adjustment effect, forming a complete learning closed loop of "monitoring-analysis-adjustment-verification".

[0192] Deep synergy of each module:

[0193] Instruction flow: human-computer interaction module → main control machine / device cooperation module → physical device (motor, push rod, valve);

[0194] Data flow: pressure sensor 17, pressure sensor 27 and weighing sensor 30 → weighing module → verification module → decision result;

[0195] Feedback flow: SPC data of verification module → data management module → adjustment module → parameter optimization instruction → device cooperation module → feeding mechanism;

[0196] Traceability flow: all cycle data is uniformly archived by the data management module, and production reports and quality traceability chains of any batch, time and station can be generated through the human-computer interaction module.

[0197] In summary, the present application adopts a closed-loop sorting mechanism of "rotary verification and physical partitioning", and through the cam divider driving the weighing unit to accurately rotate among the four stations, it converts the weight decision (qualified / underweight / overweight) into a physical position, realizes online, automatic and non-destructive rejection of unqualified products, and ensures the weight qualification rate of the output material.

[0198] The present application constructs a complete "perception-decision-execution-optimization" data intelligent closed loop. The six software modules work together not only to control in real time, but also to analyze historical data through the adjustment module, self-learn and optimize the feeding parameters in reverse, so that the device can actively adapt to material fluctuations, upgrading from an automatic machine to an intelligent production unit.

[0199] The present application realizes flexible and high-precision production. For different material characteristics, three kinds of quantitative mechanisms of granular, vibration and turnover are integrated to optimize the feeding strategy from the source. Through redundant weighing verification and pneumatic cleaning design, the comprehensive precision, long-term stability and production efficiency are finally guaranteed.

Various modifications or changes in the specific embodiments described herein can occur to those skilled in the art to which the application pertains without departing from the spirit of the application, and it is understood that such modifications or changes are to be considered as within the scope of the application as defined by the appended claims.
