Description

Technical Field

[0001] This invention relates to the field of glass production control, and in particular to a multi-mode control system and method for a raw material verification scale. Background Technology

[0002] In glass production, raw glass materials need to be weighed using a raw material verification scale. This scale allows for precise control of the amount of raw materials input, thereby improving production quality. A raw material verification scale is typically a hopper device with both weighing and a discharge port. The weighed material is then sent to equipment such as a mixer for further production. For example, a powder conveying device, as described in patent application number 202222555624.2, includes a verification scale and a mixing and sending tank. The verification scale is positioned above the mixing and sending tank. The device also includes a powder pipeline, with its first port connected to the discharge port of the verification scale via a first butterfly valve component, and its second port connected to the mixing and sending tank via a second butterfly valve component; and a vent valve assembly, comprising a vent valve body and a vent pipe connected to the vent valve body. The vent valve body and the powder pipeline are sealed together via a flange structure, and the vent pipe is connected to the cavity of the powder pipeline to allow gas to be introduced into the powder pipeline.

[0003] As can be seen from the patent disclosure above, after weighing, the raw material verification scale transports the raw material to the mixer through a pipeline via the discharge port. However, this traditional verification scale has certain limitations. In the production process, the verification scale plays a crucial role in the accurate measurement, verification, and processing of glass raw materials. Traditional verification scales typically only have a single verification operation mode, making it difficult to efficiently handle the diversity of equipment states. For example, when the raw material is relatively accurate and does not require further verification, the presence of the verification scale leads to an increase in production cycle time, lacks flexibility, and its functional mode is limited. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-mode control system and method for a raw material verification scale, providing multiple functional modes for glass production verification scales to match different production needs.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A multi-mode control system for a raw material verification scale includes a raw material verification scale, a control unit, and a discharge gate; The output of the control unit is connected to the discharge gate to control its opening and closing; the discharge gate is used to control the discharge of raw materials from the raw material verification scale. The control unit is connected to the raw material verification scale and is used to acquire and record the raw material data verified by the raw material verification scale. The control unit has multiple preset working modes, and controls the raw material verification scale and discharge gate according to the current working mode.

[0006] The control system further includes one or more intermediate silos for temporary storage of raw materials; the inlet of the intermediate silo is connected to the outlet of the raw material verification scale via a pipe; the outlet of the intermediate silo is equipped with an intermediate silo control valve; and the output of the control unit is connected to the intermediate silo control valve.

[0007] The discharge gate is located at the outlet of the raw material verification scale to control whether or not raw materials are discharged from the raw material verification scale.

[0008] The discharge port of the raw material verification scale is connected to the inlet of the mixer via a first pipe; the discharge port of the raw material verification scale is connected to the inlet of the intermediate silo via a second pipe.

[0009] The control unit is connected to the human-machine interaction module, through which the working mode is entered or selected; the control unit controls the raw material verification scale, discharge gate, and intermediate silo control valve according to the entered or selected working mode.

[0010] The control unit has built-in working modes including verification mode, pass-through mode, and intermediate warehouse mode; When the control unit is in verification mode, the control unit weighs the raw materials based on the raw material verification scale and controls the raw materials to enter the mixer through the pipeline through the discharge gate after the weighing is completed; When the control unit is in the through mode, the control unit drives the discharge gate to keep the pipeline between the raw material verification scale outlet and the mixer in the normally open mode, so that the raw material enters the mixer directly after passing through the raw material verification scale. When the control unit is in intermediate silo mode, the control unit opens the discharge port of the raw material verification scale through the pipeline to the corresponding discharge gate of the intermediate silo, so that the verified raw material enters the intermediate silo for temporary storage.

[0011] The control unit controls the opening of the intermediate chamber valve according to the control signal from the host computer, so as to send the raw materials temporarily stored in the intermediate chamber into the mixer according to the control signal from the host computer.

[0012] The control unit monitors the working status of the mixer in real time, controls the switching between the compound mode and the intermediate silo mode based on the working status of the mixer, temporarily stores the verified raw materials in the intermediate silo, and controls the feeding of the temporarily stored raw materials in the intermediate silo into the mixer according to the production cycle and the working status of the mixer.

[0013] A control method for a multi-mode control system of a raw material verification scale includes a control unit entering a verification mode or a direct-flow mode according to user settings or selection; when the control unit is in the verification mode, the control unit switches to a compound mode and an intermediate silo mode based on real-time monitoring of the mixer's working status. When the control unit is in verification mode, the control unit weighs the raw materials based on the raw material verification scale and controls the raw materials to enter the mixer through the pipeline through the discharge gate after the weighing is completed; When the control unit is in the through mode, the control unit drives the discharge gate to keep the pipeline between the raw material verification scale outlet and the mixer in the normally open mode, so that the raw material enters the mixer directly after passing through the raw material verification scale. When the control unit is in intermediate silo mode, the control unit opens the discharge port of the raw material verification scale through the pipeline to the corresponding discharge gate of the intermediate silo, so that the verified raw material enters the intermediate silo for temporary storage.

[0014] In intermediate silo mode, the control unit controls the feeding of raw materials temporarily stored in the intermediate silo into the mixer based on the production cycle and the working status of the mixer.

[0015] The advantages of this invention are: it provides multiple functional modes for glass production verification scales to match different production needs, improves the functional modes of raw material verification scales, expands the applicable environment, can improve production efficiency, and can match different production processes.

[0017] The markings in the above diagrams are: 1. Raw material verification scale; 2. Second pipeline; 3. First pipeline; 4. Intermediate silo; 5. Mixer. Detailed Implementation

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0019] This embodiment addresses the deficiency of existing raw material verification scales, which only have one verification mode and cannot meet the diverse needs of the production process. Therefore, a control system for a raw material verification scale with multiple modes is designed, as detailed below. Figure 1 , 2As shown, a multi-mode control system for a raw material verification scale includes a raw material verification scale, a control unit, and a discharge gate. The output of the control unit is connected to the discharge gate to control its opening and closing. The discharge gate is used to control the discharge of raw materials from the raw material verification scale. The control unit is connected to the raw material verification scale to acquire and record the raw material data verified by the scale. The control unit has multiple preset operating modes, and controls the raw material verification scale and the discharge gate according to the current operating mode.

[0020] In this embodiment, the control system also includes one or more intermediate chambers for temporary storage of raw materials; the inlet of the intermediate chamber is connected to the outlet of the raw material verification scale via a pipe; the outlet of the intermediate chamber is equipped with an intermediate chamber control valve; the output of the control unit is connected to the intermediate chamber control valve.

[0021] A discharge gate is installed at the outlet of the raw material verification scale to control whether or not raw materials are discharged from the scale. The discharge gate consists of components such as a solenoid valve and a gate plate, used to control the opening and closing of the outlet.

[0022] A schematic diagram of the control system, such as... Figure 2 As shown, the transportation mechanism transports the raw materials to the raw material verification scale and then feeds them into the verification scale to verify and weigh the raw materials. The raw materials that have been verified by the raw material verification scale can be output through the discharge port to the next process, which is generally a mixer. In the mixer, the raw materials can be mixed and then continue to the next production process.

[0023] The discharge ports of the raw material verification scale are connected to the mixer and the intermediate silo, respectively. The discharge port of the raw material verification scale is connected to the feed port of the mixer via a first pipe; the discharge port of the raw material verification scale is connected to the feed port of the intermediate silo via a second pipe. A discharge gate is installed at the discharge port of the raw material verification scale, which controls the flow of raw materials from the scale into either the first or second pipe. For example, the discharge ports can be set as two independent discharge ports, with the first discharge port connected to the first pipe and the second discharge port connected to the second pipe. Each discharge port has a discharge gate. The control unit drives the first and second discharge gates to ensure that the raw materials flow into the first and second pipes. Materials flowing into the first pipe enter the mixer, while materials flowing into the second pipe enter the intermediate silo for temporary storage.

[0024] like Figure 2As shown, the intermediate chamber is used for temporary storage of raw materials after symmetrical verification. The intermediate chamber can be implemented in two ways as a working mode. The first is to use the weighing chamber of the verification scale. After weighing, when temporary storage of raw materials is needed, the discharge door can be kept closed, and the entire verification scale can be used as the intermediate chamber to temporarily store the raw materials. The raw materials are only discharged into the mixer when discharge is required. The second method is to add a new chamber as the intermediate chamber. The raw materials weighed by the verification scale are discharged into the intermediate chamber for temporary storage, and then the raw materials in the intermediate chamber are discharged into the mixer according to subsequent control. When the mixer is working at full load, or to improve efficiency and reduce waiting time for the verification scale, the weighed raw materials can be temporarily stored in the intermediate chamber. A control valve is installed at the bottom of the intermediate chamber. Through the control valve, the raw materials in the intermediate chamber can be sent into the mixer through a pipeline. The state of the control valve is controlled according to the actual situation, thereby controlling the discharge of raw materials from the intermediate chamber.

[0025] In a preferred embodiment, a human-machine interface (HMI) module is provided, and the control unit is connected to the HMI module. The HMI module allows the user to input or select a working mode. The control unit then controls the raw material verification scale, discharge gate, and intermediate silo control valves according to the input or selected working mode. The HMI module can be implemented using a touchscreen or similar device, while the control unit uses a PLC (Programmable Logic Controller) to implement the control functions. The touchscreen allows the user to input or select the corresponding working mode, and the PLC control unit controls the working status of the verification scale and the raw material conveying path according to the working mode.

[0026] In this embodiment, the control unit has built-in operating modes including review mode, pass-through mode, and / or intermediate compartment mode; When the control unit is in verification mode, the control unit weighs the raw materials based on the raw material verification scale and controls the raw materials to enter the mixer through the pipeline through the discharge gate after the weighing is completed; When the control unit is in the through mode, the control unit drives the discharge gate to keep the pipeline between the raw material verification scale outlet and the mixer in the normally open mode, so that the raw material enters the mixer directly after passing through the raw material verification scale. When the control unit is in intermediate silo mode, it opens the discharge port of the raw material verification scale via a pipeline to the corresponding discharge gate in the intermediate silo, allowing the verified raw material to enter the intermediate silo for temporary storage. The control unit controls the opening of the intermediate silo control valve based on the host computer control signal, thus feeding the temporarily stored raw material into the mixer. The control unit monitors the mixer's operating status in real time and controls the switching between compounding mode and intermediate silo mode based on the mixer's operating status, temporarily storing the verified raw material in the intermediate silo and controlling the feeding of the temporarily stored raw material into the mixer according to the production cycle and the mixer's operating status.

[0027] The control unit can autonomously determine and enter various operating modes, or the user can set them. When the control unit enters verification mode or direct-flow mode; in verification mode, the control unit switches between verification mode and intermediate silo mode based on real-time monitoring of the mixer's operating status; in verification mode, the control unit weighs the raw materials based on the raw material verification scale and, after weighing, controls the raw materials to enter the mixer through the pipeline via the discharge gate; in direct-flow mode, the control unit drives the discharge gate to keep the pipeline between the raw material verification scale outlet and the mixer in a normally open mode, so that the raw materials directly enter the mixer after passing through the raw material verification scale. When the control unit is in intermediate silo mode, it opens the discharge port of the raw material verification scale via a pipeline to the corresponding discharge gate in the intermediate silo, allowing the verified raw materials to enter the intermediate silo for temporary storage. In intermediate silo mode, the control unit controls the feeding of the temporarily stored raw materials in the intermediate silo into the mixer based on the production cycle and the mixer's operating status.

[0028] In this embodiment, the control system includes the following system architecture: Verification Weighing Device: This device is equipped with high-precision weight detection sensors, a data processing unit, and a communication module, responsible for collecting and transmitting raw material weight data. It ensures data accuracy through advanced sensing technology, performs real-time analysis and processing of the collected data through a high-speed data processing unit, and finally transmits the processed data securely and accurately to the control system via the communication module.

[0029] Conveyor Line: Serving as the link between various functional areas, including weighing belts, mixers, and intermediate storage areas, it enables the automatic transmission of weighing data. The conveyor line design takes into account the flowability and stability of materials, ensuring smooth movement of raw materials between functional areas while maintaining weighing accuracy, providing strong support for the smooth operation of the entire production process.

[0030] Intermediate warehouse: As a functional mode of the verification scale, it mainly undertakes the task of temporary storage of raw materials. It can flexibly store and release raw materials according to production needs, ensuring the continuity and stability of raw material supply, thereby improving the efficiency of the entire production line.

[0031] Control System: This system integrates a mode selection module, a data storage and analysis module, and an equipment control command sending module. It can select the appropriate operating mode and control related equipment based on preset rules and real-time data. Through intelligent algorithms, the control system analyzes production data in real time and automatically adjusts equipment operating status to ensure efficient and stable production.

[0032] Discharge gate: Composed of components such as cylinders, gate plates, and solenoid valves, it is responsible for controlling the operation of the discharge device of the verification scale. The design of the discharge gate fully considers the convenience and safety of operation, ensuring accurate and error-free discharge tasks in various working environments.

[0033] The operating mode of the control system in this embodiment is as follows: Verification Mode: After the raw materials enter the verification scale, the scale accurately measures their weight and transmits the data to the control system. The control system compares this data with pre-stored raw material weight data to determine if the weight meets process requirements. If it does, the discharge gate opens, and the raw materials are discharged to the mixer. If not, the verification scale issues an alarm for further action. Verification mode ensures that the weight of the raw materials conforms to production standards, thereby guaranteeing product quality.

[0034] Straight-through mode: For raw materials whose weighing accuracy has been confirmed or do not require verification, the discharge gate remains open in the event of a malfunction in the verification scale. When the raw material enters the verification scale area, the control system does not need to perform weighing verification; the raw material will quickly pass through the verification scale and be directly discharged to the mixer, significantly improving work efficiency. Straight-through mode is suitable for raw materials that have undergone rigorous inspection, effectively reducing unnecessary operations and accelerating the production pace.

[0035] Intermediate warehouse mode: After the raw materials arrive at the verification scale, the control system temporarily stores the raw materials on the verification scale according to the weighing status. The verification scale, according to instructions from the control system, opens the discharge gate to discharge the raw materials to the mixer when the mixer is idle, thereby saving the batching cycle and improving production efficiency. The intermediate warehouse mode optimizes the production process and reduces waiting time by rationally arranging the storage and release of raw materials.

[0036] The solution in this embodiment has the following technical advantages: 1. Glass raw materials enter the verification weighing area. The weight detection sensors of the verification weighing device acquire the weight data of the raw materials and transmit the data to the control system in real time through the communication module. The high sensitivity of the sensors ensures the accuracy of the data, while the high-speed transmission capability of the communication module ensures the real-time nature of the data, providing a reliable basis for subsequent processing and decision-making.

[0037] 2. The micromechanic determines the appropriate operating mode for the verification scale based on the actual on-site conditions, and then selects the appropriate mode through the mode selection module of the control system. The micromechanic's decision-making is based on a deep understanding of the production process and analysis of real-time data, ensuring the flexibility and adaptability of the production process.

[0038] If the verification mode is selected, the process proceeds to weight comparison and processing. If the straight-through mode is selected, instructions are sent directly to the conveyor line to deliver the glass raw materials directly to the mixer. If the intermediate silo mode is selected, the conveyor line is controlled to store the glass raw materials in the verification scale as an intermediate silo, saving the batching cycle and improving production efficiency. By flexibly utilizing different operating modes, the most suitable processing method can be selected according to the characteristics of the raw materials and production needs, thereby improving overall production efficiency and product quality.

[0039] The aforementioned system and methods for verification using a verification scale, direct-flow, and intermediate storage effectively improve the efficiency, accuracy, and flexibility of raw material production, adapting to different work scenarios and needs. This not only increases production efficiency but also ensures the consistency and reliability of product quality, providing solid technical support for the stable development of the enterprise.

[0040] The control system of the raw material verification scale in this embodiment has the following technical advantages. 1. Multi-mode dynamic cooperative control system Multi-mode parallel management: In intermediate silo mode, the system can simultaneously store and prioritize multiple batches of raw materials. Through data storage and analysis modules, combined with parameters such as raw material type and process timeliness, the system dynamically optimizes the material discharge sequence, avoiding raw material accumulation or mixer idling and improving overall production line efficiency. Specifically: Multiple intermediate silos are set up. Raw materials verified by the raw material verification scale are sent to different intermediate silos for temporary storage. Each intermediate silo containing temporary raw materials is prioritized. When the mixer is detected to be entering the next mixing cycle, the system prioritizes all intermediate silos containing temporary raw materials, selecting the highest-priority silo to open its valve and discharge the raw material into the mixer.

[0041] 2. High-precision sensing and anti-interference design Composite sensor array: The weight detection sensor adopts a multi-node distributed layout, which can maintain a weighing accuracy of ±0.1% under complex working conditions such as fluctuations in raw material flow rate and changes in ambient temperature and humidity, which is significantly better than the traditional single sensor structure (±0.5%).

[0042] Redundant data transmission mechanism: The communication module adopts dual-channel transmission (wired + wireless). When the main channel is interrupted, it automatically switches to the backup link to ensure data real-time performance and integrity, which is especially suitable for industrial scenarios with strong electromagnetic interference.

[0043] 3. Modular discharge gate structure Pneumatic-electric linkage fast response design: The gate of the discharge gate is made of lightweight composite material, and is equipped with dual cylinder drive and high frequency solenoid valve. It can complete the opening and closing action within 0.5 seconds (the traditional structure takes 1.5 seconds), and supports local fine adjustment (such as opening 50% for slow release discharge) to avoid damage to the mixer caused by raw material impact.

[0044] 4. Resource optimization mechanism of the intermediate warehouse model Dynamic capacity allocation technology: The intermediate silo can automatically adjust its upper limit of temporary storage capacity according to the mixer's working rhythm. For example, when the mixer is fully loaded, the intermediate silo expands to 80% capacity to buffer the raw material flow; when the mixer is idle, it quickly releases raw materials to 90% empty state, reducing waiting time. That is, when the mixer is detected to be fully loaded, 80% of the capacity in the intermediate silo is activated to temporarily store raw materials. The raw materials temporarily stored in the intermediate silo provide a basis for quickly feeding raw materials into the mixer when it is idle. When the mixer is detected to be idle, the raw materials temporarily stored in the intermediate silo are given priority to be fed into the mixer, and the intermediate silo is emptied first to make room for the next raw material storage and emptying.

[0045] Energy consumption optimization strategies: 5. Integration of Human-Computer Interaction and Remote Control Visualized operating interface: The control system is equipped with a touch screen, which supports one-click operation for mode switching, parameter setting, and fault diagnosis, and displays data such as raw material weight and equipment health status in real time, reducing the technical threshold for operators.

[0046] Cloud-based data interconnection: Supports uploading production data to the cloud platform via the Industrial Internet of Things (IIoT) to enable remote monitoring and big data analysis, providing decision support for process optimization (such as predictive maintenance and raw material ratio optimization).

[0047] Blockchain traceability application: By embedding blockchain technology into the verification mode, the raw material weighing data can be recorded in an immutable manner, meeting the quality traceability needs of high-end manufacturing industries.

[0048] Through the aforementioned innovations, this technological improvement not only solves the problem of insufficient flexibility in traditional verification scales, but also achieves industry-leading levels in terms of accuracy, reliability, intelligence, and energy efficiency, providing key technological support for the digital transformation of glass raw material production.

[0049] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
