DETAILED DESCRIPTION OF THE EMBODIMENTS

[0009] The present application provides a packaging equipment control method based on product features, which is used to solve the technical problems that the existing technology mostly controls the packaging equipment based on fixed programs, with low flexibility and unable to ensure the stability and reliability of packaging quality.

[0010] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present application belong to the scope of protection of the present application.

[0011] It should be noted that the terms "first", "second", etc. in the description of this application and the above-mentioned drawings are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that such data used can be interchanged under appropriate circumstances so that the embodiments of this application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or server that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or modules that are not clearly listed or are inherent to these processes, methods, products or devices.

[0012] Embodiment 1 As Figure 1 shown, this application provides a packaging equipment control method based on product characteristics, and the method includes: P10: Read the packaging process of the target product, and orient the monitoring point cloud based on product characteristics. The monitoring point cloud is determined based on key points and risk points, and there are point cloud spatio-temporal identifiers and index threshold identifiers.

[0013] First, read the packaging process information of the target product, including physical characteristics such as the size, shape, material, and weight of the target product, as well as process parameters such as temperature, humidity, and pressure required during the packaging process. Further, take the physical characteristics and process parameters of the product as product characteristics, and identify the key points that need special attention during the packaging process. For example, for fragile products, the key points are vibration and impact during packaging, and for products that need to maintain a specific temperature, temperature control is the key point. In addition to the key points, it is also necessary to identify the nodes that may pose risks during the packaging process. The risk points may be potential problems caused by equipment failures, human operation errors, or other factors. Integrate the key points and risk points to locate the monitoring point cloud, and each monitoring point cloud has its specific spatio-temporal identifier and index threshold identifier. The spatio-temporal identifier is the position and time identifier of the monitoring point cloud, and the index threshold identifier is the identifier of the allowable range of the key indicators that the monitoring point cloud needs to monitor, such as the temperature threshold identifier. By accurately locating the key monitoring points in the packaging process, that is, the monitoring point cloud, it can provide an important basis for subsequent packaging process monitoring and feedback regulation.

[0014] Further, as Figure 2 shown, step P10 of the embodiment of this application further includes: P11: Based on the product characteristics, perform industrial big data retrieval to determine multiple groups of data records, including packaging records and transportation records; P12: Mine the index thresholds based on the multiple groups of data records. Each product characteristic corresponds to at least one index, including general indexes and personalized indexes. The index threshold is the critical index value based on the expected packaging quality. P13: Determine the mapping relationship between the indexes and process parameters, and perform threshold expansion on the index thresholds based on a preset interval according to the control sensitivity, where the control sensitivity is positively correlated with the preset interval.

[0015] Optionally, the specific process of positioning the monitoring point cloud guided by product characteristics can be as follows. First, retrieve in the industrial big database according to the product characteristics to find multiple groups of data records related to the target product. These records may include packaging records, transportation records, etc., which can provide a reference for determining the key indexes and thresholds in the packaging process. Further, based on the multiple groups of data records, extract the key indexes related to the product characteristics and the corresponding index thresholds through data mining technology. Each product characteristic corresponds to at least one index, and the key indexes may include general indexes such as packaging speed and packaging accuracy, as well as personalized indexes such as special packaging requirements for specific products. The index threshold is the critical index value based on the expected packaging quality, representing the maximum or minimum value of each index in the packaging process.

[0016] Further, through the principle of the packaging production process, collect and analyze historical data to clarify the mapping relationship between each key index and the packaging process parameters. One index may correspond to multiple parameters, which helps to quickly identify and adjust the process parameters related to a specific index during the monitoring process. And perform expansion on the index thresholds based on a preset interval according to the control sensitivity. The control sensitivity reflects the sensitivity of each index to the change of the packaging process parameters. Exemplarily, when the control sensitivity of a certain index is high, it means that the index is more sensitive to the change of the process parameters. Therefore, a wider threshold interval needs to be set for it to avoid false alarms or misoperations caused by minor changes, so that even if there are certain interference deviations in the actual control, it is still under the normal control standard. The preset interval can be set by professionals according to experience or experimental data and has a positive correlation with the control sensitivity.

[0017] P20: Collaborate the packaging mechanism and the conveyor belt to construct a limit control module, where the limit control dimensions include transmission limit and packaging limit.

[0018] Further, step P20 of the embodiment of the present application further includes: P21: Read the standard limit scenario based on the entire packaging cycle, determine the first position grid based on the standard position space, and construct a standardized branch, where the first position grid includes the limit scenarios of multiple process nodes. P22: Based on the real-time position space conversion of the packaging equipment - target product, build an operational branch; P23: Parallelize the standardized branch and the operational branch, and use the integrated probability network of distributed limit pairs as the decision-making method to generate the limit control module.

[0019] It should be understood that the collaborative packaging mechanism and the conveyor belt jointly construct the limit control module. The limit control module is responsible for ensuring the position accuracy and safety of the product during transmission and packaging. The limit control dimensions mainly include transmission limit and packaging limit.

[0020] Specifically, first read the standard limit scenario based on the entire packaging cycle. The standard limit scenario can be determined based on a large amount of historical data and expert experience, covering all stages from the start of product transmission to the completion of packaging. Further, based on the standard position space, determine the first position grid. The first position grid divides the space of the packaging process into multiple regions, and each region corresponds to one or more process nodes, such as loading, positioning, encapsulation, etc. And each process node has its specific limit scenario, which describes the expected position of the product and the allowable movement range at that node.

[0021] Further, using the first position grid, the system constructs a standardized branch. The standardized branch is a control path preset based on the standard limit scenario, used to guide the behavior of the packaging equipment and the conveyor belt at different process nodes. Further, through sensors and other devices, real-time obtain the position information of the target product and the packaging equipment, and based on the real-time position space conversion of the packaging equipment - target product, build an operational branch. The operational branch is a control path dynamically generated according to the actual operation situation, aiming to ensure that the product can be transmitted and packaged along the expected path and speed.

[0022] Further, process the standardized branch and the operational branch in parallel, that is, consider the preset standard path and real-time operation data simultaneously, and use the integrated probability network of distributed limit pairs as the decision-making method. The integrated probability network of distributed limit pairs is a complex calculation model that combines multiple limit pairs, that is, information on the limit requirements at different process nodes, and makes decisions based on probability theory and statistical methods. Through this decision-making method, comprehensively consider multiple factors, such as product characteristics, equipment status, environmental conditions, etc., to generate the optimal limit control instruction. And based on the optimal limit control instruction, generate the limit control module. The limit control module is an executable control program, responsible for real-time monitoring the position and status of the product, and adjusting the behavior of the conveyor belt and the packaging mechanism as needed to ensure that the product can be transmitted and packaged along the expected path and speed.

[0023] P30: Based on an optoelectronic counter, perform fixed-point counting of the target product on the conveyor belt to generate equipment operation instructions. When the count is incremented by 1, the equipment operation instructions are generated.

[0024] Specifically, using the principle and function of the optoelectronic counter, perform precise fixed-point counting of the target product on the conveyor belt. When any target product passes through the detection area of the optoelectronic counter, the counter will increment by 1, and corresponding equipment operation instructions will be generated based on this counting result.

[0025] Among them, the optoelectronic counter is installed at a specific position on the conveyor belt, which is the only way for the target product to pass through. And the optoelectronic counter detects whether a product passes by emitting and receiving light beams. When the target product passes through the detection area of the optoelectronic counter, the counter will sense the change in the light beam, such as the light beam being blocked, thus determining that a product has passed. At this time, the counter will increment by 1 and record the quantity of the product.

[0026] Based on the count value of the counter, generate corresponding equipment operation instructions. The equipment operation instructions may include controlling the speed of the conveyor belt, starting or stopping the packaging mechanism, adjusting packaging parameters, etc. For example, when the count reaches a preset threshold, generate an instruction to pause the conveyor belt for the next round of packaging operations.

[0027] P40: Based on the packaging process, perform PLC control settings for the packaging equipment. With the reception of the equipment operation instructions, perform the initial braking of the packaging cycle.

[0028] Optionally, for the packaging process, perform PLC control settings for the packaging equipment. PLC is a programmable logic controller. When the equipment operation instructions are received, the PLC will trigger the initial braking of the packaging cycle according to the operation instructions, thereby starting or adjusting the packaging process. Specifically, according to the specific requirements of the packaging process, first configure the control parameters of the PLC, including the start conditions of the equipment, operation modes, speed settings, position adjustments, etc. When receiving the equipment operation instructions from the optoelectronic counter, the PLC will perform logical judgments and trigger corresponding control actions according to the instruction content. The content of the equipment operation instructions may include start, stop, acceleration, deceleration, position adjustment, etc., which can reflect the status and requirements of the products on the current production line. If the instruction is to start a new packaging cycle, the PLC will perform the initial braking operation, that is, start each packaging equipment or component in sequence according to the preset process flow to start a new packaging cycle.

[0029] P50: For the packaging equipment, perform limit control for the entire packaging cycle in combination with the limit control module and packaging braking control based on the PLC side.

[0030] In a possible embodiment of the present application, by real-time monitoring the operating state of the packaging equipment and combining with the limit control module for full-cycle limit control, including product stacking on the conveyor belt, spatial orientation adjustment, and various limit requirements during the packaging process. The limit control module dynamically adjusts the positions and parameters of each limit point according to the preset limit scenarios and real-time data to ensure the stability and safety of the product during transmission and packaging.

[0031] Meanwhile, communicate with the PLC side, receive the device operation instructions sent by the PLC, and perform packaging braking control according to these instructions, including actions such as starting, stopping, accelerating, decelerating, etc., and the coordinated movement of each device component. The PLC calculates the optimal braking control strategy according to the preset process parameters and real-time data, and sends it to each actuator through the control system to achieve precise packaging braking control.

[0032] Furthermore, step P50 of the embodiment of the present application further includes: P51: Receive the device operation instructions, take the product stacking as the first transmission limit dimension and the product spatial orientation as the second transmission limit dimension, and perform handover coaxial limit control based on the conveyor belt and the packaging equipment; P52: Perform packaging coaxial limit control based on the device component and the product packaging position.

[0033] Specifically, the automatic control based on the PLC is under a fixed program. In practice, the product cannot guarantee the same operation position every time. Therefore, the limit module is combined for adjustment before execution. When the product is transferred from the conveyor belt to the packaging equipment, according to the product stacking, that is, the first transmission limit dimension, and the product spatial orientation, that is, the second transmission limit dimension, handover coaxial limit control is performed to ensure that the product can accurately reach the specified packaging position during transmission and avoid collision or deviation with the equipment.

[0034] During the packaging process, packaging coaxial limit control is performed according to the device component and the product packaging position, the position and state of the product are monitored in real time, and by adjusting the position and parameters of the device component, precise packaging coaxial limit control is achieved to ensure that the product can be accurately placed at the predetermined position during packaging and avoid the product from moving or tilting during the packaging process.

[0035] Furthermore, as Figure 3 shown, step P52 of the embodiment of the present application further includes: P52-1: Based on the practical operation branch, convert the real-time limit scenario of the first process node to determine the actual position space; P52-2: Based on the standardization branch, retrieve the standard position space of the first process node; P52-3: Determine the distributed limit pairs based on the first process node, map the actual position space and the standard position space, measure the position difference, and determine the integrated probability network, where the distributed limit pairs are distribution points located in the target product and the equipment components for coaxiality limitation, and the integrated probability network includes the probability of the position difference of each limit pair affecting the packaging energy efficiency; P52-4: Based on the integrated probability network, determine the limit control requirement, generate a limit control instruction, and make an adjustment decision based on the position difference.

[0036] Specifically, based on the practical branch, convert the real-time limit scenario of the first process node. The position information of the target product in the packaging equipment can be obtained in real time through sensors and other devices to determine the actual position space of the product during the packaging process, that is, the actual position and posture of the product at the first process node. Further, based on the standardization branch, retrieve the standard position space of the first process node, that is, extract the position and posture that the product should be in under ideal conditions from the standard parameter space.

[0037] Further, determine the distributed limit pairs based on the first process node. These limit pairs are distribution points located in the target product and the equipment components for coaxiality limitation. By mapping the actual position space and the standard position space, measure the position difference between the two. The position difference reflects the deviation degree between the actual product and the standard state. And based on the position difference, determine the integrated probability network. The integrated probability network takes into account the probability of the position difference of each limit pair affecting the packaging energy efficiency, so as to comprehensively evaluate the coaxiality of the product in the current state.

[0038] Further, based on the evaluation result of the integrated probability network, determine the limit control requirement. If the determination result indicates that limit control is required, generate the corresponding limit control instruction. And send the limit control instruction to the actuator, such as a motor, a cylinder, etc., to drive the actuator to make the corresponding position adjustment to reduce the difference between the actual position and the standard position, so as to improve the coaxiality of the product. After executing the adjustment decision, continuously monitor the position and state of the product, and repeat the above steps as needed to ensure that the coaxiality of the product is always maintained at a high level throughout the packaging process.

[0039] P60: Synchronously perform control monitoring. Based on the monitored point cloud, quickly identify the point cloud data of the packaging data and determine the index threshold, and perform feedback control management.

[0040] Specifically, the operating status of the packaging equipment is monitored in real time, and the monitoring point cloud data of the packaging process is captured through a sensor network. The monitoring point cloud data includes, but is not limited to, key indicators such as product position, speed, acceleration, temperature, and humidity. The captured monitoring point cloud data is quickly identified, key information is extracted, and based on the preset index thresholds, the key information is judged to determine whether there are abnormal or non-compliant situations. When the judgment result shows that there are abnormalities or non-compliance, the feedback regulation mechanism is activated, and corresponding regulation measures are taken according to the degree of abnormality or non-compliance, such as adjusting equipment parameters, suspending equipment operation, etc., for feedback regulation management.

[0041] Furthermore, step P60 of the embodiment of the present application further includes: P61: For the monitoring point cloud, determine the feedback regulation logic, which is determined based on the unit regulation relationship of index-associated parameter control; P62: Map the monitoring point cloud and the feedback regulation logic, and configure a digital feedback device; P63: Based on the digital feedback device, perform control deviation decision-making and autonomous feedback analysis on the point cloud data, generate a feedback control strategy, and perform single-frequency feedback regulation.

[0042] Optionally, the process of the feedback regulation management may be to determine the feedback regulation logic based on the unit regulation relationship of index-associated parameter control. The feedback regulation logic describes how to adjust the parameters or actuators associated with it when a certain index is abnormal. Map the monitoring point cloud data and the feedback regulation logic to ensure that the system can accurately identify the regulation measures corresponding to each monitoring point cloud data, and configure a digital feedback device, which may be a software module or algorithm for automatically performing feedback regulation according to the mapping relationship.

[0043] Furthermore, based on the digital feedback device, performing control deviation decision-making on the point cloud data includes judging the deviation degree between the actual state and the desired state and determining whether regulation is required. Then, according to the result of the control deviation decision-making and the monitoring point cloud data, autonomous feedback analysis is performed to generate a specific feedback control strategy, and the feedback control strategy includes parameters such as specific regulation measures, actuators, regulation time, and amplitude.

[0044] Furthermore, according to the generated feedback control strategy, single-frequency feedback regulation is performed, that is, the feedback regulation is periodically executed at a preset frequency to ensure that the packaging process is always under control. During the regulation process, the operating status of the packaging equipment and the product quality are continuously monitored, and the feedback control strategy is dynamically adjusted as needed to ensure the efficiency, accuracy, and safety of the packaging process.

[0045] Furthermore, step P63 of the embodiment of the present application further includes: P63-1: Read the feedback control strategy for the preset cycle, and mine the pre-adjustment control points that meet the frequency threshold. The pre-adjustment control points include pre-adjustment parameters - amplitude modulation; P63-2: Based on the pre-adjustment control points, perform mapping regulation and update of the PLC control program.

[0046] It should be understood that in actual applications, it is also necessary to continuously optimize and adjust the feedback control strategy and the PLC control program according to the specific production situation and equipment characteristics to further improve the efficiency and quality of the packaging process. First, read the feedback control strategy for the preset cycle. The preset cycle, such as every hour, every day, etc., can be set according to the actual control accuracy requirements. The feedback control strategy includes the regulation measures taken for various abnormal situations or non-conforming situations in the packaging process.

[0047] Furthermore, perform data mining and analysis on the feedback control strategy, and screen out the pre-adjustment control points that meet the frequency threshold, that is, the pre-adjustment control points that are frequently called. The frequency threshold can be set according to empirical values and sample sizes. The pre-adjustment control points refer to the control points that are frequently applied and adjusted in multiple cycles or multiple regulations, and usually correspond to some key parameters or actuators. And the pre-adjustment control points include pre-adjustment parameters and amplitude modulation. The pre-adjustment parameters refer to the equipment parameters or actuators that need to be adjusted, while the amplitude modulation refers to the degree or range by which these parameters or actuators need to be adjusted.

[0048] Furthermore, map the pre-adjustment control points to the PLC control program and perform corresponding regulation and update, such as modifying the relevant parameter settings in the PLC control program, adjusting the control logic of the actuator, etc. The updated PLC control program will be able to more accurately reflect the problems that may occur in the packaging process and the corresponding regulation measures, thereby improving the stability and reliability of the entire packaging process.

[0049] In summary, the embodiments of the present application at least have the following technical effects: Through the packaging process, the present application performs PLC control settings for packaging equipment and initial braking of the packaging cycle; coordinates the packaging mechanism and the conveyor belt, constructs a limit control module, performs limit control for the entire packaging cycle, and performs packaging braking control based on the PLC side, synchronously performs control monitoring, and performs feedback regulation management based on the monitoring point cloud.

[0050] It achieves the technical effect of ensuring the stability and reliability of packaging quality through synchronous control monitoring and feedback regulation management by combining limit control and PLC-side braking control.
