Description

Technical Field

[0001] The invention relates to the technical field of packaging, in particular to an automatic packaging and processing production line for egg boxes. Background Art

[0002] The egg product packaging and processing production line is a system that provides automated packaging solutions for egg products (such as chicken eggs, duck eggs, etc.). The automated characteristics of the packaging and processing production line enable companies to process a large number of products in a short period of time, reduce labor costs, and improve production efficiency. Modern egg product packaging and processing production lines can also be equipped with high-tech labeling equipment, so that each egg package can be labeled accurately and in compliance with regulations, which not only improves production speed, but also strengthens the ability to track and manage products.

[0003] The existing packaging labeling device is shown in the Chinese application with application number: 201610119142.9: Labeling machine and labeling method. The labeling machine includes a frame, a label supply mechanism, a product material strip supply mechanism, a bonding platform and a suction labeling mechanism; the suction labeling mechanism and the bonding platform are opposite to each other and are respectively located above and below the middle section of the product material strip's path; the suction labeling mechanism includes a suction label plate and a lifting drive member; the label supply mechanism includes a material discharge component, a label stripping plate component and a material receiving component, the label stripping plate component includes a label stripping plate and a horizontal displacement drive member, the end of the label stripping plate close to the suction labeling mechanism is the label stripping end, and the label stripping end is located between the lower surface of the label suction plate and the upper surface of the product material strip. The label suction plate moves downward under the drive of the lifting drive member to absorb and peel off the label from the label material strip on the stripping end, and further descends after the label stripping plate is retracted to bond the label to the product material strip.

[0004] The prior art has the following defects. In the above-mentioned labeling machine, there is a situation where the label suction plate and the product material strip cannot be aligned. If the label suction plate fails to be aligned with the product material strip during the label peeling and attachment process, the label may be offset, causing the actual position of the label to be inconsistent with the product. Due to inaccurate label attachment, additional manual intervention or secondary processing may be required, which will extend the production cycle and reduce overall efficiency. Misalignment may cause the label to be unable to be properly attached to the product, making it difficult to reuse and causing unnecessary material waste, so there is room for improvement.

[0006] The present invention is achieved through the following technical solutions:

[0012] Preferably, the adjustment component includes a gear, which is rotatably installed on the limit member, a rack is provided on the first conveyor belt, the gear is meshed with the rack, and the gear is driven to rotate by a driving mechanism. The label-discharging component pushes a complete label to the equal-position component, which is recorded as a first working condition, and the label-discharging component pushes an incomplete label, which is recorded as a second working condition.

[0018] 1. Through the setting of the adjustment component, the egg box can be accurately adjusted to the correct position and direction to facilitate the subsequent glue spraying and labeling operations. When the adjustment component detects that the egg box has not been adjusted to the appropriate position, it will send a feedback signal to the control terminal. The control terminal adjusts the working state of the speed adjustment component according to the feedback of the adjustment component, reduces the label discharge speed, and ensures the synchronization of the egg box and the label; the speed adjustment component can dynamically adjust the label discharge speed according to the real-time status of the production line. When the adjustment component fails to adjust the egg box to the appropriate position, the speed adjustment component will reduce the label discharge speed according to the instruction of the control terminal to synchronize with the progress of the egg box adjustment. If the position adjustment time of the egg box is too long, the adjustment component will temporarily enter the delayed waiting state, and the speed adjustment component will also synchronously slow down the label discharge speed to prevent the label from being pushed out before the egg box is in place. The control terminal will monitor the status of the label discharge component and decide whether to delay or start the recovery component according to its feedback to maintain the dynamic stability of the entire production line, achieve accurate alignment of the label and the egg box, and improve the labeling efficiency and quality of the egg box;

[0019] 2. Through the setting of the speed regulating component, when the label output component pushes out two labels, along with the pushing out of the label paper, the gap between the first roller and the second roller becomes larger, and the displacement detector monitors the displacement of the second mounting block in real time, and feeds back the data to the control terminal. The control terminal can instantly adjust the position of the equal position component and the recycling component, so that the recycling port of the recycling component corresponds to the position of the unqualified label on the speed regulating component; the control terminal adjusts the speed of the driving mechanism of the first roller and the second roller, so that one group of labels can be smoothly recycled into the label output component, reducing the generation of unqualified products and protecting the effective operation of the production line. The speed regulating component can quickly recycle unqualified labels to prevent them from being attached to products. By effectively managing the utilization rate of labels and reducing the number of misplaced labels, the entire production system can reduce material waste and reduce overall production costs;

[0020] 3. Calculate the actual center axis position of the egg box through the pressure value of each point, transmit the actual center axis position to the control terminal, compare the actual center axis position with the preset center axis position, and command the adjustment component to move so that the actual center axis coincides with the preset center axis position. Through accurate calculation and correction of the center axis position of the egg box, ensure that the label can be accurately positioned on the egg box during the labeling process. The system can respond to changes in the position of the egg box in real time, reduce the defective rate caused by inaccurate labeling, reduce scrap costs, improve resource utilization, and thus reduce production costs overall.

[0037] See also Figure 1-Figure 5 , an egg box automatic packaging and processing production line, including a feeding mechanism 1, a conveying mechanism 2, a glue spraying mechanism 3, a labeling mechanism 4, a pressing mechanism 5, a stacking mechanism 6 and a control terminal 7, the feeding mechanism 1 is used to grab the egg box 8 and place the egg box 8 on the conveying structure, the conveying mechanism 2 is used to convey the egg box 8 to the glue spraying mechanism 3, the labeling mechanism 4, the pressing mechanism 5 and the stacking mechanism 6 in sequence, the glue spraying mechanism 3 is used to spray glue evenly on the surface of the egg box 8, the pressing mechanism 5 is used to attach the label to the surface of the egg box 8, and the stacking mechanism 6 is used to stack the labeled egg boxes 8; the conveying mechanism 2 includes a first conveying component 21, The first conveying component 21 includes a first conveying belt 211, a limit member 212 and an adjusting component 213. The limit member 212 is slidably set on the first conveying belt 211. The egg box 8 is buckled on the limit member 212. The adjusting component 213 is used to adjust the position and direction of the egg box 8. The label laying mechanism 4 includes a label output component 41, a speed regulating component 42 and a recycling component 43. The label output component 41 is used to push the label out according to a preset program. The speed regulating component 42 is used to adjust the discharging speed of the label. The recycling component 43 is used to recycle unqualified labels. The adjusting component 213, the speed regulating component 42 and the recycling component 43 are communicatively connected to the control terminal 7.

[0038] The main function of the unloading mechanism 1 is to grab the egg box 8 from the raw material pile and place it accurately on the conveying structure, so as to realize automatic grabbing and placement, reduce manual intervention, improve the discharging efficiency, ensure the accurate placement of the egg box 8, and lay the foundation for the subsequent process; the unloading mechanism 1 includes two feeding troughs and a vacuum absorber. The staff manually places the egg box in the feeding trough. The feeding trough ensures the correct placement of the egg box. The vacuum absorber includes a pump, a valve, a filter, a pipe and a suction cup. The vacuum absorber is used to process the egg box on the feeding trough and adsorb it to the conveying mechanism 2. The vacuum suction cup can adsorb 6-18 egg boxes at a time, and can unload up to 90 egg boxes per minute; the conveying mechanism 2 is responsible for conveying the egg box 8 to each workstation (sprayer) in turn. Glue, labeling, pressing, and stacking), through the first conveying component 21 (including the conveyor belt, the limiter 212, and the adjusting component 213), the continuous conveying of the egg box 8 is realized to ensure the smoothness of the production line. The limiter 212 can ensure the fixed position of the egg box 8 on the conveyor belt, and the adjusting component 213 can adjust the direction of the egg box 8 for subsequent operations; the glue spraying mechanism 3 is responsible for spraying glue evenly on the surface of the egg box 8 to ensure uniform glue spraying and improve the bonding quality between the label and the egg box 8. The glue spraying amount can be adjusted to meet the product requirements of different batches. The glue spraying mechanism 3 sprays glue on three sides of the egg box on the conveyor belt according to the setting parameters on the control terminal 7; the labeling mechanism 4 accurately attaches the label to the egg box 8. Its core parts include a label discharging component 41, a speed regulating component 42 and a recycling component 43. The staff places the label in the label placement slot of the label discharging component 1. The design of the label discharging component 41 can ensure that the label is pushed out according to the preset program to ensure that each egg box 8 has the correct label. The speed regulating component 42 allows the production line to dynamically adjust the label discharging speed according to the production efficiency requirements to adapt to the production rhythm. Compared with traditional labeling machines, the present invention avoids the position error between the label and the product, and significantly improves the labeling efficiency and quality. The recycling component 43 can automatically recycle unqualified labels, reduce waste and improve production efficiency. The labeling machines in the prior art often require manual intervention when processing unqualified labels, while the present invention realizes automated processing, reduces labor costs and improves production efficiency. Compared with traditional production lines, the present invention reduces downtime and material waste while maintaining efficient production, thereby improving overall production efficiency.

[0039] The pressing mechanism 5 is used to fit the label to the surface of the egg box 8. After the label's front plane is pressed and positioned, the label is folded down so that the two sides of the label fit the two boxes of the egg box, ensuring that the label fits tightly and preventing the label from falling off or shifting, thereby improving the overall appearance and quality of the package. The pressure can be adjusted according to the egg boxes 8 of different materials and weights to ensure the best pressing effect. The labeling machine in the prior art can often only realize the labeling operation of a single plane, while the present invention provides a more comprehensive and flexible labeling solution; the stacking mechanism 6 reasonably stacks the labeled egg boxes 8. By stacking, the use of storage space is optimized, making subsequent transportation and storage more efficient. The stacked egg boxes 8 are easy to carry mechanically or manually, thereby improving work efficiency. The stacking mechanism 6 includes a cam drive rod and blades. The cam drive rod is provided with four groups. The blades are provided on the cam drive rod. Each cam Three groups of blades are arranged on the driving rod, and the blades stack the egg cartons with labels on the conveyor belt. A counter is also arranged on the stacking mechanism 6 for recording the number of egg cartons with labels, so as to facilitate real-time monitoring of the stacking quantity and status. The control terminal 7 is responsible for communication, monitoring and coordination between various components, so as to realize the automatic packaging and processing production line of egg cartons 8 of the entire production line. The production line has multiple functional modules, and each module works together to realize an efficient and automated egg box 8 packaging process. A total control terminal 7 is adopted to complete the automatic unloading and stacking of egg cartons and the monitoring and management of the entire production process. Through the precise control of the control terminal 7, the coordinated work between various components is realized, and the stability and reliability of the production line are ensured. Compared with the decentralized control mode in the traditional production line, the present invention realizes more efficient and reliable production management through the integrated total control system.

[0040] The adjusting component 213 is responsible for accurately adjusting the egg box 8 to the correct position and direction to facilitate the subsequent glue spraying and labeling operations. When the adjusting component 213 detects that the egg box 8 has not been adjusted to the appropriate position, it will send a feedback signal to the control terminal 7. The control terminal 7 adjusts the working state of the speed regulating component 42 according to the feedback of the adjusting component 213, reduces the discharging speed of the label, and ensures the synchronization of the egg box 8 and the label; the speed regulating component 42 can dynamically adjust the discharging speed of the label according to the real-time status of the production line. When the adjusting component 213 fails to adjust the egg box 8 to the appropriate position, the speed regulating component 42 will reduce the discharging speed of the label according to the instruction of the control terminal 7, so as to synchronize with the progress of the egg box 8 adjustment. If the position adjustment time of the egg box 8 is too long, the adjusting component 213 will temporarily enter In the delayed waiting state, the speed regulating component 42 will also synchronously slow down the discharging speed of the label to prevent the label from being pushed out before the egg box 8 is in place; the recycling component 43 is responsible for recycling the labels that have not been successfully discharged or do not meet the requirements to ensure the quality of the final product. By automatically recycling unqualified labels, resource waste can be reduced and production efficiency can be improved; when the label issuing component 41 fails to successfully complete the pushing of the label (such as incomplete, double sheets, etc.), the recycling component 43 will automatically recycle the label according to the instructions of the control terminal 7. Once the recycling component 43 starts to work, it will feedback the completed status to the control terminal 7, so as to facilitate the control system to adjust the next step of the label issuing operation. The control terminal 7 receives signals from the adjustment component 213, the speed regulating component 42 and the recycling component 43 to make a comprehensive judgment. For example, if the adjustment component 213 feedbacks that the egg box 8 is not in place, the control terminal 7 instructs the speed adjustment component 42 to reduce the label discharge speed. In the label discharge state, the control terminal 7 will monitor the state of the label discharge component 41, and decide whether to delay or start the recovery component 43 based on its feedback, so as to maintain the dynamic stability of the entire production line, achieve precise alignment of the label and the egg box 8, and improve the labeling efficiency and quality of the egg box 8.

[0041] In order to provide a certain buffer between the labeling component 41 and the speed regulating component 42 and reduce the impact of labeling errors on the production line, based on this, in one embodiment, the labeling mechanism 4 also includes an equal position component 44, which is arranged between the labeling component 41 and the speed regulating component 42. The equal position component 44 includes a first cylinder 441 and a conveyor belt 442. The first cylinder 441 is used to drive the conveyor belt 442 to move in the vertical direction, and the conveyor belt 442 transfers the label from the labeling component 41 to the speed regulating component 42. The equal position component 44 ensures the accurate position of the label between the labeling component 41 and the speed regulating component 42, prevents the misalignment, overlap or blank of the label, saves horizontal space through vertical movement, makes the overall design of the production line more compact, and adapts to the application environment with limited space; the equal position component 44 plays an important buffering and mitigating role in the process of the label from the labeling component 41 to the speed regulating component 42. It can adjust the relative position of the label and the egg box 8, provide support for subsequent speed adjustment, and avoid accumulation and confusion caused by early or delayed label delivery. If there is no equal-position component 44, the label may fall directly from the label output component 41 into the speed regulation component 42, which may easily cause the label to be misplaced or stuck. In standardized operations, the equal-position component 44 can effectively reduce the misplacement and paper jam problems caused by improper operation, thereby reducing the probability of failure in the production process. The existence of the equal-position component 44 enables the system to flexibly adjust the label discharge process. A certain buffer is provided between the labeling component 41 and the speed regulating component 42, which can realize efficient label control without frequent shutdown for adjustment; when the visual sensor detects a labeling error on the box body, the system can immediately activate the equal position component 44 to quickly re-eject the new label from the labeling component 41, and quickly transport the new label to the speed regulating component 42 so that the egg box 8 can be relabeled. The fast response time significantly reduces the impact of errors on the production line; fast label replacement can reduce the product failure rate caused by incorrect labeling and reduce the downtime of the production line, thereby maximizing the protection of production efficiency and reducing unnecessary waste; when the labeling error is quickly identified and processed, the production line can be kept running to ensure that the output is not affected by the error, and the production rhythm can be restored in time to improve the overall production capacity.

[0042] In order to quickly recover labels with abnormal discharge and prevent them from continuing to affect the operation of the production line, in one embodiment, a recovery component 43 is arranged between the label output component 41 and the speed regulating component 42, and the recovery component 43 includes a second cylinder 431 and a recovery trough 432. The second cylinder 431 is used to drive the recovery trough 432 to move in the vertical direction, and the recovery trough 432 is used to transport the labels on the speed regulating component 42 back to the label output component 41. The second cylinder 431 is used to drive the vertical movement of the recovery slot 432 to ensure that it can smoothly collect labels. The recovery slot 432 is used to receive labels that cannot be properly attached from the speed regulating component 42, and convey these labels back to the labeling component 41 for proper processing or reuse. When the labels cannot be effectively attached due to faults (such as overlap, paper jam, etc.) during the conveying process of the speed regulating component 42, the recovery component 43 captures and recycles these labels in time to avoid unnecessary waste of materials. The design of the recovery component 43 enables all label problems on the production line to be quickly identified and processed. When the speed regulating component 42 finds that the label is abnormal (such as incomplete or double), the recovery slot 432 can quickly retract the label to prevent it from continuing to affect the operation of the production line. Since the label can be quickly recovered and processed, the downtime of the production line is greatly reduced, and there is no need for cumbersome manual cleaning and maintenance. The recovery component 43 can effectively prevent the wrong label from continuing to be attached to the egg box 8. Once a problem with the label is detected, feedback can be quickly provided to ensure that product quality is not affected.

[0043] In order to improve the fault tolerance of the entire unloading process and ensure that the egg box 8 maintains the correct position during the glue spraying, labeling and laminating processes, based on this, in one embodiment, the conveying mechanism 2 also includes a second conveying component 22, and the second conveying component 22 includes a second conveyor belt 221 and limit blocks 222. The limit blocks 222 are evenly spaced on the second conveyor belt 221. The unloading mechanism 1 places the egg box 8 between two adjacent groups of limit blocks 222. The second conveyor belt 221 is used to convey the egg box 8 to the glue spraying mechanism 3, the labeling mechanism 4, the laminating mechanism 5 and the stacking mechanism 6 in sequence. The first conveyor belt 211 transfers the egg box 8 from the glue spraying mechanism 3, the labeling mechanism, the laminating mechanism 5 to the stacking mechanism 6 in sequence. Placing the egg box 8 between two adjacent groups of limit blocks 222 ensures that the egg box 8 can be accurately placed in the desired position during the material feeding process, reducing errors caused by improper material feeding. The limit blocks 222 provide a physical position reference for material feeding, effectively reducing the possibility of misalignment. The design of the limit blocks 222 improves the fault tolerance of the entire material feeding process. Even if there is a slight deviation during the material feeding process (such as a slight offset in the placement of the egg box 8), due to the existence of the limit blocks 222, it can be effectively adjusted back to the correct position, reducing the impact of human operation on production efficiency. The design of the second conveyor belt 221 partially overlapping the limit blocks 222 can ensure that the egg box 8 maintains the correct position during the glue spraying, labeling and laminating processes, prevent sliding or misalignment, and improve the overall stability of production. When the labeling mechanism 4 is pasting the label, the egg box 8 is restricted by the limit blocks 222 to ensure the accurate position, thereby effectively improving the label fitting accuracy. This precise placement is crucial to the appearance and pass rate of the final product, especially in mass production, where any small errors will be magnified; since the egg box 8 is effectively positioned during transportation, the reliance on manual labor is reduced. For example, the operator does not need to intervene frequently to adjust the position, which not only improves work efficiency but also reduces the rate of manual errors; the stable transportation and fixed-point design means that downtime caused by misplaced labels or improper material feeding can be reduced, thus improving overall production efficiency.

[0044] In order to effectively prevent mis-sticking of labels and improve the labeling quality of the production line, based on this, in one embodiment, the speed regulating component 42 includes a frame 421, a first mounting block 422, a second mounting block 423, a first roller 424, a second roller 425, a spring 426 and a displacement detector 427. A slide groove is vertically arranged on the frame 421, the first mounting block 422 is fixed to the bottom of the slide groove, the second mounting block 423 is slidably installed in the slide groove, the second mounting block 423 is arranged at the top of the first mounting block 422, the spring 426 is arranged between the inner top surface of the slide groove and the top surface of the second mounting block 423, and the displacement detector 427 is arranged on the top surface of the second mounting block 423; the first roller 424 is rotatably installed on the first mounting block 422, the second roller 425 is rotatably installed on the second mounting block 423, and the label is pushed out from between the first roller 424 and the second roller 425, and the first roller 424 and the second roller 425 are driven by independent driving mechanisms. When the label output component 41 pushes out two labels, along with the pushing out of the label paper, the gap between the first roller 424 and the second roller 425 becomes larger. This change is caused by the compression of the spring 426, and at the same time changes the height of the second mounting block 423; the displacement detector 427 monitors the displacement of the second mounting block 423 in real time and feeds back the data to the control terminal 7. This provides important information for the cause of the gap change, indicating the possible abnormality or need for adjustment of the component; based on the information provided by the displacement detector 427, the control terminal 7 can instantly adjust the position of the equal position component 44 and the recovery component 43, so that the recovery port of the recovery component 43 corresponds to the position of the unqualified label on the speed control component 42; the control terminal 7 adjusts the speed of the driving mechanism of the first roller 424 and the second roller 425, so that one group of labels can be smoothly recovered into the label output component 41; through real-time monitoring and feedback, the speed control component 42 can automatically adapt to the changes in the label push-out, and by ensuring the accuracy of the position of the label when it is pushed in and recovered, the speed control component 42 can effectively prevent the label from being mis-sticked, thereby improving the labeling quality of the production line as a whole. Ensuring the alignment and correct position of labels is critical, especially in a high-speed production environment. The system can respond to potential problems in a timely manner through real-time data provided by the displacement detector 427. When too many labels are pushed out or the quality is poor, quick action can be taken to reduce the production of defective products and protect the effective operation of the production line. The speed control component 42 can quickly recycle defective labels to prevent them from being attached to products. By effectively managing the utilization rate of labels and reducing the number of misplaced labels, the entire production system can reduce material waste and reduce overall production costs.

[0045] In order to enable the adjustment component 213 to quickly respond to the delayed waiting state when an unqualified label appears, the recycling component 43 to recycle the label in time, and the waiting component 44 to quickly replace the label, so as to maintain the continuity and efficiency of the production process, based on this, in one embodiment, the adjustment component 213 includes a gear, which is rotatably installed on the limit member 212, and a rack is provided on the first conveyor belt 211. The gear is meshed with the rack, and the gear is driven to rotate by a driving mechanism. The label output component 41 pushes a complete label to the waiting component 44, which is recorded as a first working condition, and the label output component 41 pushes an incomplete label, which is recorded as a second working condition. When the label output component 41 is in the first working condition, the limit member 212 is located at the initial position of the first conveyor belt 211. When the label output component 41 is in the second working condition, the driving mechanism drives the limit member 212 to move on the first conveyor belt 211, so that the limit member 212 and the label output component 41 remain stationary. The gear is rotatably installed on the limiter 212 and meshes with the rack on the first conveyor belt 211. The rotation of the gear is controlled by the driving mechanism, thereby realizing the position adjustment of the limiter 212. The label component 41 successfully pushes out a complete label, and the limiter 212 remains in the initial position. The entire label flow and labeling process is normal. The label component 41 pushes out an incomplete label. The driving mechanism adjusts the position of the gear to make the limiter 212 enter a delayed waiting state, so as to recover unqualified labels and quickly obtain new labels. Under the second working condition, the system can detect the pushed incomplete labels in real time. By moving the limiter 212 to the delayed waiting state, unqualified labels can be effectively prevented from continuing to be transmitted downstream, avoiding these labels from affecting the subsequent production process. This immediate response mechanism reflects the system's emphasis on quality control and helps maintain the standards of the final product. The design of the adjustment component 213 allows the entire system to achieve automated processing and improves the efficiency of label delivery and lamination. When the label ejection component 41 pushes out the complete label, the static state of the limiter 212 allows the whole batch of labels to be processed continuously and smoothly; the fully automated adjustment mechanism reduces the reliance on the operator and reduces the possibility of human error. In the production line, because some labels may be accidentally pushed out, traditional manual inspection or intervention may cause delays and production bottlenecks, and the weak control mechanism of the adjustment component 213 ensures that the system can self-adjust and improve the overall operation safety and reliability; once an unqualified label is detected, the system quickly recycles it and extracts a new label from the equal position component 44 for replacement. The smooth progress of this process ensures the perfect fit between the product bottom box and the label, avoids additional misalignment and adjustment caused by label problems, and effectively reduces the production of defective products.

[0046] In order to ensure the accurate delivery of the label, so that it is accurately attached to the product without misalignment, and reduce material waste, based on this, in one embodiment, the label component 41 pushes two complete labels to the equal position component 44 as the third working condition. When the label component 41 is in the third working condition, the control terminal 7 adjusts the speed of the driving mechanism of the first roller 424 and the second roller 425 and the second cylinder 431, so that the first roller 424 and the second roller 425 rotate in opposite directions, so as to realize the delivery of one label to the egg box 8 and the recovery of the other label into the label component 41. The third working condition refers to the label component 41 successfully pushing two complete labels to the equal position component 44. In this state, the system needs to coordinate the work of multiple devices to achieve efficient labeling. When in the third working state, the control terminal 7 is responsible for adjusting the speed of the driving mechanism of the first roller 424 and the second roller 425 and the action of the second cylinder 431. By reverse rotation, one label will be delivered to the egg box 8, and the other label will be recovered in the label output component 41; processing two labels at the same time reduces the label release process in the production cycle, which helps to improve the output of the overall production line. This measure effectively supports high-speed production needs and is particularly suitable for large-scale production occasions; by controlling the reverse rotation of the first roller 424 and the second roller 425, the accurate delivery of the label is ensured so that it is accurately attached to the product (such as the egg box 8) without misalignment; the control of reverse rotation enables the system to flexibly respond to the advancement and recovery of the label and switch the operation state in time. This dynamic management reduces the risk of unqualified labels affecting subsequent processing links and helps to improve the stability of the entire production process; delivering one label to the egg box 8 and recovering the other label in the label output component 41 helps to maximize the use of all label resources. This optimized label usage strategy reduces material waste, lowers production costs, and improves label utilization; due to the optimization of the labeling process, the increased degree of automation reduces labor costs, reduces the loss of unqualified products, improves production efficiency, and thus reduces production costs overall.

[0047] In order to ensure that each operation link is completed within the specified time and avoid production rhythm disorder caused by delay, based on this, in one embodiment, when the movement time of the limiter 212 on the first conveyor belt 211 is less than the preset time, the limiter 212 continues to move on the first conveyor belt 211, and when the movement time of the limiter 212 on the first conveyor belt 211 is equal to the preset time, the limiter 212 moves in the opposite direction to the initial position and issues a labeling abnormality alarm. By setting the movement time of the limiter 212 on the first conveyor belt 211, the system can ensure that each operation link is completed within the specified time and avoid production rhythm disorder caused by delay; when the movement time of the limiter 212 reaches the preset value, the system will not only take measures to move in the opposite direction, but also issue an alarm. This monitoring and feedback mechanism ensures real-time monitoring of the production line and can detect and handle abnormal situations in a timely manner; the movement time of the limiter 212 on the first conveyor belt 211 is monitored to ensure that it completes the movement within the specified time. If the preset time is exceeded, the design of reverse movement to the initial station can effectively avoid the delay of the limiter 212 affecting the subsequent egg box 8 operation process, reducing the risk of production stagnation; through timely feedback and adjustment, the system can maintain the efficient operation of the production line. The setting of the limiter 212 continuing to move on the first conveyor belt 211 ensures smooth operation under normal conditions, while the timely reverse movement under abnormal conditions prevents potential production bottlenecks; the design of issuing an abnormal labeling alarm provides operators with timely feedback, enabling rapid identification and resolution of problems. This alarm mechanism not only improves the transparency of the production process, but also enhances the ability to monitor the status of the equipment and reduces the possibility of human error.

[0048] In order to allow the system to adjust the position of the bottom box under different conditions and adapt to egg boxes 8 of various specifications, based on this, in one embodiment, the adjustment component 213 also includes a rotating plate 2131, a third cylinder 2132 and an adjustment plate 2133. The rotating plate 2131 is rotatably mounted on the limiter 212, the third cylinder 2132 is arranged on the rotating plate 2131, and the adjustment plate 2133 is arranged at the movable end of the third cylinder 2132, and the adjustment plate 2133 abuts against the inner surface of the egg box 8. The rotating plate 2131 is mounted on the limiter 212 and has the ability to rotate. Its main function is to realize the adjustment of the subsequent operation position. The third cylinder 2132 is arranged on the rotating plate 2131 and is responsible for driving the lifting or movement of the adjustment plate 2133. The third cylinder 2132 usually works by using air pressure, which can achieve fast and accurate displacement; the adjustment plate 2133 installed at the movable end of the third cylinder 2132 abuts against the inner surface of the egg box 8, and is adjusted up and down or left and right according to the action of the third cylinder 2132; when the adjustment component 213 is working, the start and stop of the third cylinder 2132 will drive the rotation of the rotating plate 2131 and the movement of the adjustment plate 2133, so that the position or posture of the egg box 8 can be dynamically adjusted; the rotation of the rotating plate 2131 is combined with the up and down movement of the third cylinder 2132, so that the adjustment plate 2133 can be accurately aligned with the inside of the egg box 8, ensuring that it can adapt to egg boxes 8 of various shapes and specifications; the adjustment plate 2133 The close contact between 133 and the inner surface of the egg box 8 ensures the precise positioning of the label during the labeling process. No matter how the shape of the egg box 8 changes, the adjustment plate 2133 can be adjusted in time to improve the accuracy of labeling and reduce the deviation of the label, thereby ensuring the consistency of product appearance. Since the egg box 8 may have different sizes and shapes, the flexibility of the rotating plate 2131 and the third cylinder 2132 allows the system to adjust the position of the adjustment plate 2133 under different conditions to adapt to egg boxes 8 of various specifications. The fast adjustment function of the adjustment component 213 reduces downtime when changing lines or adjusting operations, ensuring the continuity and smoothness of the production line. The system can quickly adapt to production changes and maintain efficient production capacity.

[0049] In order to accurately calculate and correct the position of the central axis of the egg box 8 and ensure that the label can be accurately positioned on the egg box 8 during the labeling process, based on this, in one embodiment, the adjustment plate 2133 is provided with a first detection point 9, a second detection point 10, a third detection point 11 and a fourth detection point 12, and the first detection point 9, the second detection point 10, the third detection point 11 and the fourth detection point 12 are all provided with pressure sensors, and the pressure sensors are used to detect the pressure of each point, and the actual central axis position of the egg box 8 is calculated by the pressure value of each point, and the actual central axis position is transmitted to the control terminal 7, and the actual central axis position is compared with the preset central axis position, and the adjustment component 213 is instructed to move so that the actual central axis coincides with the preset central axis position. The four detection points are respectively located on the adjustment plate 2133, responsible for pressure detection at different positions, and each detection point is equipped with a pressure sensor to monitor the pressure value of each point in real time; when the egg box 8 is placed on the adjustment plate 2133, the pressure sensor will sense the pressure applied to different points. By measuring these pressure values, the system can calculate the actual center axis position of the egg box 8, and the actual center axis position will be transmitted to the control terminal 7 through the system. The control terminal 7 presets the ideal center axis position, and then compares the actual measured center axis position with the preset position; if the actual center axis does not match the preset center axis, the control terminal 7 will send an instruction to prompt the adjustment component 213 to move accordingly to ensure that the actual center axis coincides with the preset center axis; by accurately calculating and correcting the center axis position of the egg box 8, it is ensured that the label can be accurately positioned on the egg box 8 during the labeling process. The system can respond to the changes in the position of the egg box 8 in real time, especially in high-volume production, and can be adjusted quickly to ensure the accuracy of each labeling link; during the production process, due to material errors (such as slight irregularities in the shape, material or placement of the egg box 8, etc.), the actual center axis may deviate from the preset center axis. The system effectively corrects these errors by continuously monitoring the pressure value and adjusting in real time to maintain the normal operation of the production line; because it can reduce the defective rate caused by inaccurate labeling, reduce the waste cost, improve resource utilization, and thus reduce the production cost as a whole.

[0050] The pressure values ​​of the pressure sensors at the four corners of the adjustment plate are: P1, P2, P3, P4, and the actual center axis position of the egg box (X a , Y a ),in,

[0051]

[0052] W is the width of the adjustment plate, and L is the length of the adjustment plate;

[0053] X aIn the formula, (P1+P2) represents the sum of the pressures received by the sensors at the two corners of the front end, (P1+P2+P3+P4) is the sum of the pressures of each pressure sensor, and represents the intensity of the system's response to the entire egg box. The result is multiplied by the width W of the adjustment plate to convert the actual absolute position of the center axis in the width direction. Y a The logic of the formula is similar. The pressure P1 at the front left corner is compared with the pressure P3 at the rear left corner. The ratio of the pressure P1 to the total is calculated to obtain the actual position in the length direction. Assuming that the pressure value is proportional to the actual placement of the egg box, that is, the more stable the placement, the higher the reading of a certain pressure sensor. The sum of the pressure values ​​at different corners can be used to deduce the actual center axis of the egg box relative to the center of the adjustment plate, and feedback and adjustment can be achieved.

[0054] The control terminal will X a With the preset center axis position X p Compare and create deviations:

[0055] ΔX=X p -X a ,

[0056] ΔY=Y p -Y a ;

[0057] According to the deviation values ​​ΔX and ΔY, the action of the mechanical components is adjusted in time, and the control instructions can be designed as:

[0058] If ΔX>0, move to the right, if ΔX<0, move to the left;

[0059] If ΔY>0, move forward, if ΔY<0, move backward.
