Description

Technical Field

[0001] This invention relates to the field of concrete specimen curing technology, specifically to an optimized method for fully automated multi-layer curing process of concrete specimens based on MES. Background Technology

[0002] Concrete test blocks serve as a crucial basis for evaluating the quality of concrete structural engineering projects. The standardization and traceability of their preparation, curing, and testing directly impact the accuracy and impartiality of engineering quality evaluation. Traditional test block management methods heavily rely on manual operation, with each step—from sampling, molding, demolding to curing and testing—being fragmented, resulting in inherent drawbacks such as significant human interference and inconsistent standard implementation. With the development of intelligent manufacturing and information technology, the concrete industry has an urgent need for the automation, digitalization, and process integration of test block management, aiming to achieve precise control and data management throughout the entire process.

[0003] In existing technologies, the curing and management of concrete test blocks mostly rely on manual or partially mechanized methods. During material collection and molding, manual sampling from the mixer truck or discharge port is common, resulting in inaccurate measurements and a high risk of contamination. Frequent manual handling during molding and settling is inefficient and damages the test blocks. During curing, test blocks are often laid flat on the ground or on simple frames, occupying a large space and resulting in poor temperature and humidity control, making it difficult to meet standard curing specifications. In terms of information management, test block information is often represented by handwritten labels or simple markings, which are easily worn and confused during circulation, leading to the loss of test block identification information and making it impossible to effectively link with original data such as production batches and mix proportions, thus breaking the quality traceability chain. Furthermore, the equipment in each stage operates independently, lacking a unified scheduling and data integration system, making it impossible to achieve automatic reminders for curing cycles, automatic sorting of expired test blocks, and automatic transmission of test data, resulting in inefficient management and a high error rate.

[0004] Therefore, there is an urgent need for an integrated solution that can cover the entire life cycle of concrete test blocks and realize the automation of physical processes and the synchronization of information flow, so as to fundamentally overcome the shortcomings of existing technologies such as inefficiency, uncontrollability, and difficulty in traceability. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an optimized method for fully automated multi-layer curing of concrete test blocks based on MES. This method integrates discrete processes such as material handling and molding, transportation and static placement, demolding and coding, multi-layer curing, and expiration testing into a fully automated process by constructing an integrated control system with the Manufacturing Execution System (MES) as the nerve center and a Programmable Logic Controller (PLC) as the execution core. At the start of test block generation, an RFID reader writes unique identification information into the mold tag, establishing a digital twin. During the transfer, handling robots and conveyor equipment work collaboratively according to instructions, with real-time status feedback. Upon warehousing, the warehouse management system records the location and timestamp. At expiration testing, the code reader re-verifies the identity and automatically pairs it with the pressure test data, uploading it to the MES. This ensures that the information of each test block is continuous, tamper-proof, and fully traceable throughout its entire lifecycle. It solves the problems of information loss and broken traceability chains caused by the errors of traditional manual recording, the fragility of labels, and the susceptibility to confusion during transfer. This achieves end-to-end transparent management of quality data from the production end to the testing end.

[0006] To solve the above-mentioned technical problems, this invention provides the following technical solution: an optimized method for fully automated multi-layer curing of concrete test blocks based on MES, the specific steps of which are as follows:

[0007] S100. The concrete mixture is extracted from the modified hopper using a concrete sampling machine and loaded into a plastic mold with an RFID tag. Vibration and surface finishing are performed during the loading process. Before loading, the inner wall of the plastic mold is dried and sprayed with release oil. At the same time, the batch, specifications and time information of the concrete are written into the RFID tag using an RFID reader.

[0008] S200: The mold with material is transported to the static rack through the material mold conveyor line, elevator and transfer robot system. The static curing is carried out for a set time and a second troweling operation is performed during the static curing period.

[0009] S300. After static curing, the static mold with material is transferred to the demolding fixture by the handling robot system. The demolding fixture separates the concrete test block from the plastic mold and uses an inkjet printer to print marking information on the surface of the concrete test block. The printed concrete test block is then loaded into the truss pallet.

[0010] S400: The truss pallet containing the test block is transported to the standard curing room via the double-speed chain conveyor line. The truss robot system is used to stack the truss pallet in multiple layers into the automated warehouse. The truss pallet is stacked in multiple layers according to the preset rules and then cured in a constant temperature and humidity environment under standard curing conditions until the set curing cycle is reached.

[0011] S500. After the curing period is reached, the concrete test block is taken out from the three-dimensional warehouse by the truss robot system. After the identification information on the surface of the concrete test block is read by the barcode reader, the concrete test block is sent to the pressure testing machine for compressive strength testing, and the test data is uploaded to the manufacturing execution system in real time.

[0012] Furthermore, in S100, the modified hopper is equipped with an outlet with a controllable valve and a cleaning nozzle for extracting more concrete mixture than the volume required for a single molding, and is equipped with a cleaning water recycling system for cleaning the outlet and the controllable valve and recycling wastewater.

[0013] Furthermore, in S100, a drying and spraying system is provided at the mold assembly station, which is used to spray release oil onto the inner and outer walls of the plastic mold.

[0014] The RFID reader writes information onto the RFID tags attached to the empty plastic mold before molding.

[0015] Furthermore, in S200, the set curing time is 24 hours; 5 hours after the curing begins, the concrete in the material mold is subjected to a secondary finishing operation using a secondary finishing tool.

[0016] Furthermore, in S300, the transport robot system picks up the concrete test blocks that have been demolded and marked and places them on the truss trays. Each truss tray is configured to hold 3 sets of standard test molds, totaling 9 concrete test blocks.

[0017] Furthermore, the collaborative working method of the transfer robot system and the handling robot system is as follows: the transfer robot system transports the mold with material from the mold assembly station to the overhead belt conveyor line, and after being transferred to the mold with material conveyor line by the elevator, the handling robot system grabs the mold with material and places it on the designated layer of the stationary material rack. The stationary material rack adopts a multi-layer structure design, and each layer is equipped with a positioning sensor.

[0018] Furthermore, in S400, the standard curing environment is maintained by an independent standard curing room environmental control system, which monitors and adjusts the temperature and humidity in the three-dimensional warehouse in real time to keep them within the constant range required for standard curing of concrete.

[0019] Furthermore, in S500, the identification information on the surface of the concrete test block read by the barcode reader is matched and verified with the original information of the concrete test block recorded in the manufacturing execution system and collected by the RFID tag, to ensure the integrity and accuracy of the data chain.

[0020] Furthermore, S500 also includes waste disposal, wherein after the compressive strength test is completed by the pressure testing machine, the resulting concrete test block fragments are centrally transported to the waste collection box via a waste conveyor belt for unified collection and disposal.

[0021] The concrete sampler, conveyor line, handling robot system, demolding tooling, inkjet printer, gantry robot system, barcode reader, and pressure testing machine involved in this method are all uniformly scheduled and coordinated by a programmable logic controller control system.

[0022] The programmable logic controller control system interacts with the manufacturing execution system in real time to execute production instructions, status monitoring, data acquisition, and information traceability management throughout the entire process from concrete material collection to test block testing.

[0023] Compared with existing technologies, this optimized method for fully automated multi-layer curing of concrete test blocks based on MES has the following advantages:

[0024] This invention constructs an integrated control system with a Manufacturing Execution System (MES) as the nerve center and a Programmable Logic Controller (PLC) as the execution core. It seamlessly connects discrete processes such as material handling and molding, transportation and static placement, mold disassembly and coding, multi-layer curing, and expiration testing into a fully automated process. At the starting point of test block generation, an RFID reader writes unique identification information into the mold tag to establish a digital twin. During the transfer, handling robots and conveyor equipment work collaboratively according to instructions, with real-time status feedback. When the test block is put into storage, the warehouse management system records the location and timestamp. When the test block is due for testing, the code reader verifies the identity again and automatically pairs it with the pressure test data and uploads it to the MES. This ensures that the information of each test block is continuous, tamper-proof, and fully traceable throughout its entire life cycle. It solves the problems of information loss and traceability chain breakage caused by traditional manual recording being prone to errors, labeling being easily damaged, and transfer being easily confused. It realizes end-to-end transparent management of quality data from the production end to the testing end.

[0034] To better understand the above technical solutions, a detailed description of the solutions will be provided below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “optimization method for fully automated multi-layer curing process of concrete test blocks based on MES,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plurality forms, unless the context clearly indicates otherwise; “plural” generally includes at least two.

[0036] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or device that includes said element.

[0037] To address the shortcomings of existing technologies, this invention first describes the concrete test block curing and management scenarios involved in this invention. This invention is primarily applied to locations requiring large-scale, standardized, traceable production and quality inspection of concrete test blocks, such as commercial concrete mixing plants, large-scale engineering laboratories, and precast component factories. In these scenarios, traditional manual or semi-automatic methods suffer from inherent drawbacks such as low efficiency, large human error, uncontrollable curing environment, chaotic information management, and low space utilization, making it difficult to meet the high requirements of modern engineering construction for the accuracy and timeliness of quality data. This invention aims to construct a fully integrated system with a Manufacturing Execution System (MES) as the information hub and automated equipment as the execution unit, achieving unmanned and intelligent management of the entire process from concrete sampling to test block strength data upload.

[0038] The core of this invention, a fully automated multi-layer curing process optimization method for concrete test blocks based on MES, lies in deeply integrating discrete, highly manual processes into a highly efficient, precise, and transparent automated closed loop through the deep fusion of material flow, information flow, and control flow. This method assigns a unique digital identity (RFID) to the test block through automatic material handling and molding in S100; S200 and S300 complete static shaping and physical marking (inkjet coding); S400 performs high-density three-dimensional curing in a controlled environment; and finally, S500 achieves automatic identification, accurate detection, and data transmission of expired test blocks. The entire process operates under the unified scheduling of a programmable logic controller (PLC) and interacts with the MES system in real time, ensuring the completeness and traceability of the lifecycle information for each set of test blocks.

[0039] Specifically, such as Figure 1 As shown, the optimization method for fully automated multi-layer curing process of concrete test blocks based on MES includes the following steps:

[0040] S100. The concrete mixture is extracted from the modified hopper using a concrete sampling machine and loaded into a plastic mold with an RFID tag. Vibration and surface finishing are performed during the loading process. Before loading, the inner wall of the plastic mold is dried and sprayed with release oil. At the same time, the batch, specifications and time information of the concrete are written into the RFID tag using an RFID reader.

[0041] S200: The mold with material is transported to the static rack through the material mold conveyor line, elevator and transfer robot system. The static curing is carried out for a set time and a second troweling operation is performed during the static curing period.

[0042] S300. After static curing, the static mold with material is transferred to the demolding fixture by the handling robot system. The demolding fixture separates the concrete test block from the plastic mold and uses an inkjet printer to print marking information on the surface of the concrete test block. The printed concrete test block is then loaded into the truss pallet.

[0043] S400: The truss pallet containing the test block is transported to the standard curing room via the double-speed chain conveyor line. The truss robot system is used to stack the truss pallet in multiple layers into the automated warehouse. The truss pallet is stacked in multiple layers according to the preset rules and then cured in a constant temperature and humidity environment under standard curing conditions until the set curing cycle is reached.

[0044] S500. After the curing period is reached, the concrete test block is taken out from the three-dimensional warehouse by the truss robot system. After the identification information on the surface of the concrete test block is read by the barcode reader, the concrete test block is sent to the pressure testing machine for compressive strength testing, and the test data is uploaded to the manufacturing execution system in real time.

[0045] like Figure 2 The schematic diagram of the overall layout structure shown in this invention illustrates how the method integrates various workstations, such as material picking, mold loading, static placement, mold removal and coding, three-dimensional curing, and inspection and waste removal, through rational planning of physical space and optimized design of logistics paths. The workstations are connected by conveyor lines, elevators, and robot systems to form a continuous automated production line. The following will describe each step in detail with reference to the attached diagrams and process steps.

[0046] In the specific implementation process, S100 is the starting point for test block generation, used to achieve precise and clean sampling of concrete mixtures, and to complete the initial shaping and information coding of the test blocks. For example... Figure 3 The material handling station shown includes a modified material hopper, a concrete sampler, and matching formwork fixtures.

[0047] First, concrete is unloaded from the mixing plant or transport vehicle into the modified hopper. The hopper has a dedicated outlet with a controllable valve and cleaning nozzle on its lower side. When sampling is required, the PLC control system issues a command, opening the controllable valve for approximately 3-5 seconds to extract slightly more concrete mix than the required volume for a single molding (3.2-3.5 liters) to ensure full filling of the mold. After sampling, the valve closes, the cleaning nozzle activates, and high-pressure water jets automatically clean the inner wall of the outlet and the valve. The resulting wastewater flows through pipes into a cleaning water recycling system, where it is filtered, settled, and reused, achieving clean production.

[0048] Subsequently, the extracted concrete enters the concrete sampling machine, while simultaneously, the empty plastic mold arrives at the mold assembly station via the empty mold conveyor line. For example... Figure 4 , Figure 5 , Figure 6 As shown, its process flow is as follows:

[0049] Mold pretreatment: The empty mold first enters the drying and oiling system. The drying and oiling system first blows away the residual moisture or dust in the mold with compressed air, and then evenly sprays a thin layer of release oil on specific areas of the inner and outer walls of the mold to ensure smooth demolding and prevent concrete from sticking.

[0050] Information writing: After pretreatment, the mold passes through an RFID reader. Based on the production task information issued by the MES system, including project name, concrete strength grade, mix proportion number, sampling time, and operator, the RFID reader writes the unique identification code and related information into the RFID tag embedded in the mold, thus establishing a digital identity for the test block.

[0051] Quantitative filling and compaction: The concrete sampler injects concrete into the pre-assigned plastic mold. A vibrator is installed under the mold. After starting, it generates high-frequency micro-amplitude vibration, which makes the concrete mixture fully compacted and evenly distributed, and initially smooths the surface.

[0052] Mold delivery and waste material handling: The mold with material that has been installed and compacted is delivered out of the workstation by the mold installation roller line. Any small amount of excess concrete that may be generated during the mold installation process is collected and properly disposed of by the concrete return system to avoid waste and site pollution.

[0053] S200 is responsible for transporting the molded test blocks to the static curing area and completing the prescribed static curing process to allow the concrete to initially set and harden. The logistics system includes a material-carrying mold conveyor line, elevators, a transfer robot system, and a handling robot system.

[0054] After the mold with material leaves the mold assembly station, it is picked up by a transfer robot system and placed on an overhead conveyor belt. The conveyor belt transports the mold to a vertical transport node, where it is transferred by an elevator to the mold with material conveyor belt serving the resting area.

[0055] The handling robot system picks up the mold with material from the conveyor line and, according to the instructions of the warehouse management system, accurately places it on the designated layer of the static material rack. The static material rack is a multi-layer steel structure, and each layer is equipped with a positioning guide device and a sensor to ensure that the mold is placed stably and accurately. The static material rack area constitutes an independent static curing area.

[0056] According to the standard requirements, the mold with the material must be placed on a static curing rack for 24 hours. During this period, the environment should be kept relatively stable, and violent vibrations should be avoided. Five hours after the start of the curing period, when the concrete has initially set but not yet fully hardened, the handling robot system will move again, grabbing the mold and placing it at the secondary finishing fixture. This fixture automatically performs a secondary smoothing operation on the surface of the test block to eliminate fine cracks caused by early plastic shrinkage, ensuring that the surface flatness of the test block meets the standard requirements. After completion, the mold is returned to its original static curing position.

[0057] After the static curing period, the test block possesses a certain early strength and can be demolded and a permanent physical marker can be applied. For example... Figure 7 The demolding station shown includes demolding fixtures, an inkjet printer, and a truss tray.

[0058] The handling robot system removes the mold with material that has been placed in the stationary position from the stationary material rack and transfers it to the demolding fixture. The demolding fixture uses a mechanical mechanism to act on the plastic mold, allowing the test block to separate smoothly from the inner wall of the mold, thus completing the demolding. After demolding, the empty mold is taken away by the robot and sent to the automatic cleaning fixture for cleaning, and then returned to the empty mold conveyor line, ready for reuse.

[0059] After demolding, the exposed concrete test blocks immediately enter the working range of the inkjet printer. Based on the RFID information corresponding to the test block in the MES system, the printer clearly prints a QR code or characters containing key information such as sample number, strength grade, and production date onto one side of the test block. This code serves as a visual workpiece number for the test block during subsequent transfer and testing, and it acts as a backup and verification mechanism with the RFID electronic tag information.

[0060] After the inkjet printing is completed, the handling robot system picks up the individual test blocks and stacks them in an orderly manner on the truss pallet. Each truss pallet is designed to stably accommodate 3 sets of standard test molds (a total of 9 test blocks), forming a unit load that facilitates subsequent mechanized handling and storage.

[0061] The S400 system significantly improves space utilization and the uniformity of the curing environment through automated storage technology. Truss pallets containing test blocks are automatically transported to the entrance of the standard curing room via a double-speed inbound conveyor line.

[0062] Inside the standard curing room, the gantry robot system operates under the command of the warehouse management system. The gantry robot system receives gantry pallets from the conveyor line and accurately stores them in the designated storage locations of the automated warehouse (i.e., gantry warehouse). The automated warehouse has a high-rise rack structure, which can realize multi-level stacking of test blocks. Its storage capacity is designed to meet the curing needs of a peak of 5,000 sets of test molds, effectively solving the problem of large footprint of flat curing.

[0063] The standard curing room is an independent, enclosed space equipped with an independent environmental control system. This system monitors the indoor environment in real time using high-precision temperature and humidity sensors and dynamically adjusts the system in conjunction with air conditioning units, humidifiers, and dehumidifiers to ensure that the indoor temperature remains constant at 20±2℃ and the relative humidity is maintained above 95% within the standard curing conditions. This centralized and controlled curing environment guarantees that all test blocks develop strength under completely consistent conditions during the preset 28-day curing cycle, eliminating the uneven environmental conditions caused by location differences in traditional curing methods.

[0064] After the 28-day curing period of the S500 is completed, the MES system automatically generates an outbound instruction. Based on this instruction, the truss robot system retrieves the truss pallet containing the test block, which has reached the curing deadline, from the corresponding location in the automated warehouse, places it on the outbound double-speed chain conveyor line, and sends it out of the standard curing room. The subsequent testing process is as follows:

[0065] Test block gripping and positioning: The handling robot system grips a single test block from the outbound conveyor line and first places it in the positioning and shaping fixture. The fixture performs position correction and attitude adjustment on the test block to ensure that it enters the subsequent process in a standard posture.

[0066] Information verification: After the posture adjustment, the test block is delivered by the robot to the bottom of the code reader. The code reader (usually a vision code reader) automatically identifies the inkjet information on the surface of the test block and uploads the read information to the MES system. The MES system automatically matches and verifies this information with the original information written into the RFID to confirm that the test block is correct and completes the information flow verification.

[0067] Compressive strength test: After the information verification is passed, the robot will transport the test block to the center of the pressure plate of the pressure testing machine. The testing machine will automatically load and execute the pressure burst test according to the information of the test block issued by MES, and record the pressure-displacement curve throughout the process.

[0068] Data Upload: After the test is completed, the pressure testing machine automatically uploads key data such as the compressive strength value and failure mode of the test block to the MES system in real time. The MES system automatically links these test data with the production information of the test block to form a complete quality traceability file.

[0069] Waste disposal: The crushed test block fragments are automatically conveyed to the waste box via a waste conveyor belt for centralized collection and cleaning.

[0070] The operation of the entire automated process relies on the top-level information control architecture. In this method, all physical equipment (concrete sampler, various conveyor lines, robot system, inkjet printer, barcode reader, pressure testing machine, environmental control system, etc.) are connected to a unified programmable logic controller (PLC) control system. The PLC, as the brain of the field control layer, is responsible for receiving instructions from the upper layer, parsing and decomposing them into specific equipment action commands, coordinating the timing and linkage between various equipment, and collecting equipment status and process parameters in real time.

[0071] The PLC control system and the Manufacturing Execution System (MES) interact in real time via Industrial Ethernet. As the core of the information layer, the MES is responsible for:

[0072] Production instruction issuance: Based on the production plan, instructions for tasks such as sampling, maintenance, and testing are issued to the PLC.

[0073] End-to-end data management: Receives and stores data throughout the entire lifecycle, including RFID writing, inkjet printing content, inbound / outbound time, environmental data, and stress test results.

[0074] Visual monitoring and traceability: Through an industrial computer or touch screen interface, the system displays the production line status, equipment operation, inventory information, and test results in real time, providing data query and traceability functions, and can locate the entire production and testing record of any test block.

[0075] Alarms and Diagnostics: The system has comprehensive fault alarm and diagnostic functions. When equipment malfunctions or process parameters exceed the limits, it can promptly provide alarm information to assist operators in quickly troubleshooting the fault.

[0076] In summary, this invention, through equipment automation and information management at each step, constructs a fully automated and information-based concrete test block quality management system, from concrete raw materials to strength test reports. This method not only replaces human labor with machines, greatly improving work efficiency and consistency, but also achieves precise prevention and rapid traceability of quality problems through data-driven approaches, providing a practical technical solution for the digital transformation of quality control in the concrete industry.
