Description

Technical Field

[0001] The present invention relates to a labeling mechanism, and in particular to a labeling mechanism for a labeling machine in the field of labeling devices. Background Art

[0002] A labeling machine is a device that automatically adheres paper or metal foil labels to the surface of packaging containers using adhesive. Its core labeling mechanism integrates a label supply structure (including a label bin and label pusher), a label removal component, a gluing module, an interlocking device, and a control system. Through precise coordination, it completes the entire label process from peeling off the backing paper to accurately attaching the label. However, during the labeling process, existing labeling mechanisms can cause the label to shift and skew due to insufficient adhesion to the product or loose tension in the label reel. This can lead to poor label adhesion and reduce label quality.

[0003] To address the issue of label tightness, Chinese invention patent application CN117383022A discloses a labeling mechanism that utilizes a rotating roller with a rubber airbag and a linked extrusion mechanism. Driven by a motor, this mechanism utilizes an air conduction mechanism to periodically expand the rubber sleeve, creating a dynamic compression effect on the label, effectively improving the tightness of the label to the carrier. This solution primarily addresses the problem of label deviation caused by tension relaxation during conveyance, enhancing adhesion through physical pressure, and significantly improving quality control in high-speed labeling scenarios.

[0004] To address the challenge of controlling tension between the unwinding and rewinding webs, Chinese invention patent application CN117550200A discloses a labeling machine comprising an unwinding roller, a labeling assembly, a traction roller, a rewinding roller, and a rotary drive assembly. This machine utilizes a cam-and-swing arm linkage mechanism, replacing the traditional drive mechanism. This mechanical coupling between the first swing roller and the unwinding roller achieves constant tension in the paper web. This drive-free design not only simplifies the control system but also fundamentally avoids tension fluctuations caused by speed synchronization errors, providing a mechanical guarantee for continuous and stable labeling.

[0005] While these technologies have achieved breakthroughs in pressurized lamination and tension control, existing solutions still have significant limitations. When executing multi-batch production tasks, manual gauge calibration is required for each label change, which not only increases production line downtime but also carries the risk of accuracy drift. This operator-dependent gauge adjustment method cannot meet micron-level precision alignment requirements, and the cumulative effect of errors can cause persistent label adhesion and misalignment, ultimately leading to a loss of accuracy in the placement of the entire batch of products. Summary of the Invention

[0006] In view of the above-mentioned existing technology, the technical problem to be solved by the present invention is how to solve the problem that when changing the label, the adjustment of the scale length depends on the author's experience, which not only leads to prolonged production line downtime, but also the risk of accuracy drift in manual adjustment.

[0052] Second implementation method:

[0053] Figure 1 - Figure 9 The figure shows a labeling mechanism for a labeling machine, comprising a labeling roller assembly 3 mounted on the upper side of the labeling machine body 1 and an intelligent gauge length auxiliary system mounted in a labeling control box 11. A label removal knife 4 and a labeling shovel 41 located above the label removal knife 4 are mounted on the lower right side of the labeling roller assembly 3. The label removal knife 4 and the labeling shovel 41 cooperate to peel off the label 6. The label 6 is wound around the labeling roller assembly 3.

[0054] A tension sensing component 5 that cooperates with the label 6 is fixedly installed on the right end of the labeling roller group 3, and the tension sensing component 5 is located on the upper side of the labeling knife 4. A gauge length photoelectric sensor 31 that cooperates with the label 6 is fixedly installed on the upper side of the labeling roller group 3. The right end of the labeling shovel 41 is fixedly connected to an attachment guide 411. The attachment guide 411 can support and press the label 6 attached to the labeled product 7 to maintain its effective adhesion to the labeled product 7 and prevent the label 6 from warping or poor adhesion on the labeled product 7. A header photoelectric sensor 412 that cooperates with the label 6 is fixedly installed at the lower end of the attachment guide 411;

[0055] The intelligent gauge length auxiliary system includes a gauge length intelligent processing unit. The input end of the gauge length intelligent processing unit is connected to the gauge length self-test unit, the stop position sensing unit, the gauge feeding tension sensing unit and the product position sensing unit. The output end of the gauge length intelligent processing unit is connected to the gauge feeding coordination unit and the product feeding coordination unit.

[0056] The gauge length self-test unit can use the gauge length photoelectric sensor 31 to detect the label and the base paper, and then confirm the label spacing to avoid inconsistency between the actual gauge length and the parameter input gauge length, and then perform two-way verification through the sensing of the stop position;

[0057] The stop position sensing unit uses the sensing data of the stop position to monitor the margin of the label head position of the label 6 peeled off by the label removal knife 4, collects and verifies the data of the new label, and promotes the automatic adjustment of the gauge length. It can also collect and verify the error of the labeling operation based on the data of each stop position, so as to achieve subsequent error compensation;

[0058] The input end of the gauge length self-test unit is connected to the gauge length photoelectric sensor 31 signal, the input end of the stop mark position sensing unit is connected to the header photoelectric sensor 412 signal, the input end of the label feeding tension sensing unit is connected to the tension sensing component 5 signal, the input end of the product position sensing unit is connected to the infrared sensor signal installed on the right side of the label picking knife 4, and the output ends of the label feeding coordination unit and the product feeding coordination unit are both connected to the automatic control system signal installed in the labeling control box 11. Through the coordinated cooperation of the gauge length photoelectric sensor 31, the header photoelectric sensor 412, the tension sensing component 5 and the intelligent gauge length auxiliary system, the full monitoring of the labeling data can be achieved, and the dual intelligence and automation of the label changing and labeling processes can be realized. The regulating function, on the one hand, realizes the automatic regulation of the gauge length and the stop position when changing labels, and reduces the labeling error and the difficulty of labeling regulation after labeling, while effectively promoting the efficiency and accuracy of labeling and reducing the verification cost of labeling. On the other hand, it can also continuously monitor the gauge length and the stop position during the labeling process, and effectively predict and compensate for the control error and the labeling error, so as to avoid the label adhesion and deviation caused by the continuous accumulation of errors, and ensure the labeling accuracy of batch products. It can also further promote the effect and accuracy of labeling regulation and compensation through the dual regulation between labeling and products, promote labeling efficiency, and effectively promote the economy of labeling mechanism when applied to batch products.

[0059] It should be noted that the automatic control system is the control system of the labeling machine body 1 in the prior art. It is directly quoted here without making any changes to its principles and mechanisms. Through the connection of the signal interface, it can realize the signal interconnection with the intelligent gauge length auxiliary system. The automatic control system can control the rotation and speed of the labeling roller group 3, realize the control of the automatic winding, unwinding and labeling stop of the labeling roller group 3, and can also adjust the tension of the labeling roller group 3. The tension control here can be manual or automatic. The manual method is that when changing the label, the technician uses the bolt to drive the tension wheel to move and adjust the tension of the label 6. The automatic method is automatic. The automated control system uses a pneumatic tension wheel to adjust the tension of the label 6, so as to ensure the tension balance of the label 6 when it is reeled in and unreeled, and ensure the effectiveness of its labeling; the automated control system can control the labeling conveying mechanism 2 to produce an action, realize the automated conveying of the product, and can control the speed of the labeling conveying mechanism 2 to ensure the continuity and effectiveness of product conveying; the automated control system can display the labeling data and feedback the labeling data through the control panel 12, and can also generate an alarm signal through the control panel 12 to remind the technicians of labeling abnormalities. Those skilled in the art can make functional choices for the automated control system according to their needs, and will not go into details here.

[0060] Figure 5 - Figure 7The tension sensing assembly 5 is shown to include a pair of guide rod mounting blocks 51 fixedly mounted on the rear right end of the labeling roller group 3 and distributed up and down, a guide rod is fixedly connected between the upper and lower guide rod mounting blocks 51, the guide rod is connected to a slider 52 via a locking bolt, the right end of the slider 52 is connected to a spacing adjustment block 53 via a spacing adjustment bolt, the upper end of the spacing adjustment block 53 is fixedly connected to a duckbill sensing block 54, the left and right inner walls of the duckbill sensing block 54 are fixedly connected to elastic deformation layers 55 that match the label 6, the input end of the labeling status sensing unit is connected to the signal of the pressure sensing probe arranged in the elastic deformation layer 55, the cooperation of the labeling status sensing unit and the pressure probe can effectively realize the monitoring of the operating status of the label 6, and can effectively increase the monitoring of application environment factors when predicting and eliminating labeling errors, promote the prediction accuracy of error generation, and ensure the accuracy and effectiveness of the coordination effect.

[0061] Figure 1 - Figure 3 and Figure 5 - Figure 7 The elastic deformation layer 55 is provided with a sensing control cavity, and a pressure sensing probe is installed in the sensing control cavity. Electromagnetic control blocks are fixedly connected to the inner walls on both sides of the sensing control cavity, and an isolation spring is fixedly connected between the two electromagnetic control blocks.

[0062] The output end of the gauge length intelligent processing unit is also connected to a tension compensation unit, and the output end of the tension compensation unit is connected to the electromagnetic adjustment block signal. The cooperation between the tension compensation unit and the elastic deformation layer 55 can effectively realize the tension compensation and tension dynamic application when tension error or tension change occurs during the operation of the label 6. While ensuring the effectiveness of the subsequent labeling error and the coordination of label change data, it can also achieve multi-level synergy of the label change and labeling process through the regulation of tension compensation, further promote the regulation accuracy of label change and labeling, promote the accuracy of label attachment position, and promote the economy of labeling mechanism application.

[0063] When 6 is not provided in the two 55 of 54, 55 maintains a constant extension state due to its own elasticity and the elasticity of the isolation spring, so that the two 55 are in a close contact state. When 6 is inserted between the two 55, due to the tilt of 6 in 54, the two 55 are squeezed, and the pressure sensing probe can transmit the tension state data of 6 to the pressure data.

[0064] When the pressure sensing probe transmits a large tension pressure to the labeling status sensing unit, it means that the tilt pressure generated by 6 on 55 is large at this time, and 6 is in a relatively tight state under the squeezing of the two 55, and then the tension compensation unit can act on the electromagnetic adjustment blocks in the two 55, so that they generate an electromagnetic force of attraction, driving the two 55 to simultaneously produce a contraction effect, thereby releasing the clamping effect on 6, effectively releasing the tension of 6, and avoiding damage to 6 caused by continuous tension; when the pressure sensing probe transmits a small tension pressure to the labeling status sensing unit, it means that the tilt pressure generated by 6 on 55 is small at this time, and 6 is in a relatively tight state between the two Under the extrusion of 55, it is in a relatively relaxed state, and then the tension compensation unit can act on the electromagnetic adjustment block in 55 on one side, causing it to produce a repulsive electromagnetic effect, driving 55 on one side to produce an elongated deformation, causing it to produce an extrusion effect on 6, and driving 6 to produce an effect of approaching the unregulated 5 on the other side, thereby achieving the effect of enhancing the tension on 6, avoiding poor transportation or damage caused by relaxation of 6, and an arc chamfer is provided on the end where the two 55 are close to each other, which can maintain the effectiveness of 6 moving in the two 55 when the extension of 55 on one side acts on 6 to tighten it, thereby reducing the transmission resistance of 6 and maintaining the effectiveness of transmission.

[0065] Figure 1 - Figure 3 It is shown that the input end of the gauge length intelligent processing unit is also connected to an operation data acquisition unit and a labeling parameter instruction unit. The input end of the operation data acquisition unit is connected to the signal of the automation control system installed in the labeling control box 11, and the input end of the labeling parameter instruction unit is connected to the signal of the control panel 12 set on the labeling machine body 1. The setting of the operation data acquisition unit can realize the collection of various data of the labeling process, and effectively identify the state of the labeling mechanism at this time according to the corresponding operation data, thereby providing effective data support for subsequent automatic coordination, promoting the intelligence level and automation accuracy of the labeling mechanism, and the setting of the labeling parameter instruction unit can effectively realize the interactivity between the labeling mechanism and the technicians, and can perform two-way data verification through the setting of manual parameters and the collection of operation parameters to ensure the effectiveness and accuracy of subsequent coordination.

[0066] Figure 1 - Figure 3The labeling conveying mechanism 2 is shown to be installed on the upper side of the labeling machine body 1 and located on the lower side of the labeling roller group 3. A conveying guide sleeve 21 is installed on the left end of the labeling conveying mechanism 2. A blocking guide roller 22 located on the right side of the conveying guide sleeve 21 is rotatably installed on the front side of the left end of the labeling conveying mechanism 2. A blocking steering motor is installed on the front side of the left end of the labeling conveying mechanism 2. The output shaft of the blocking steering motor is connected to the front end of the blocking guide roller 22 through a crank. The output end of the gauge length intelligent processing unit is also connected to the product interval control unit. The output end of the product interval control unit is connected to the signal of the blocking steering motor. The conveying guide sleeve 21, the blocking guide roller 22 and the product interval control unit cooperate. It can further promote the multi-level coordination of the labeling mechanism. When errors or abnormalities occur in the label length or stop position, it can timely block the release of the product and regulate the product release interval to ensure the accuracy of labeling under effective product transportation. It can effectively release the product interval according to the labeling data, thereby ensuring the labeling accuracy while effectively ensuring the labeling efficiency and effectiveness. It can promote the accuracy of the labeling position from the way the product is released, thereby avoiding the problem of difficult elimination of labeling errors caused by insufficient regulation accuracy of the labeling machine body 1 itself, further ensuring the accuracy of labeling regulation, and promoting the intelligence level of labeling coordination.

[0067] Figure 1 - Figure 8 It is shown that when changing the label, the technician wraps the new label around the labeling roller group 3, and after adjusting the tension, uses the control panel 12 to input the basic parameter output of the new label into the labeling parameter instruction unit, including but not limited to relevant data such as gauge length, stop position range, label feeding speed, label transmission tension range, product conveying range and label attachment position, and uses the control panel 12 to input the label changing status instruction into the labeling parameter instruction unit. The labeling parameter instruction unit transmits these parameter data and label changing status instruction to the gauge length intelligent processing unit. The gauge length intelligent processing unit controls the labeling roller group 3 or controls the labeling roller group 3 through the label feeding coordination unit to generate a single label feeding operation data, causing the label 6 to move on the labeling roller group 3. The gauge length photoelectric sensor 31 can perform optical sensing on the gauge length of the label 6 during movement, and then transmit the sensing data to the gauge length self-test unit. The header photoelectric sensor 412 can sense the header stop position data of the label 6 located on the right side of the label picking knife 4, and then transmit the sensing data to the stop position sensing unit. The pressure sensing probe can detect the tension data of the label 6 in the stop state and the running state, and then transmit the detection data to the label feeding tension sensing unit. The gauge length self-test unit, the stop position sensing unit and the label feeding tension sensing unit can transmit the sensed data to the gauge length intelligent processing unit, and the gauge length intelligent processing unit makes data judgment and comparison on the gauge length, the header stop position and the tension of the label 6 in each state.

[0068] When it is judged that the self-test gauge length data is consistent with the gauge length data in the input parameters, the stop position data is judged to be within the set range, and the tension data of label 6 in the stop state and running state are judged to be within the set range, the gauge length intelligent processing unit will not have any regulatory effect on the subsequent label delivery and product delivery data.

[0069] When it is determined that the self-tested gauge length data is inconsistent with the gauge length data in the input parameters, and the stop position and the tension data of the label 6 in each state are within the set range, the gauge length intelligent processing unit controls the labeling roller group 3 or the label delivery coordination unit to control the labeling roller group 3 to generate a single label delivery operation data again, and re-detects and verifies the gauge length of the label 6. After the verification result is inconsistent with the judgment result, a signal output and a label change alarm are generated through the control panel 12 to remind the technicians to inspect and maintain the label 6 and the labeling roller group 3. After the verification result is consistent with the judgment result, the gauge length intelligent processing unit iterates the gauge length data, and then coordinates and calculates the label delivery and product delivery data in combination with the received data, and then transmits the corresponding coordination data to the label delivery coordination unit and the product delivery coordination unit respectively, so that the label delivery coordination unit and the product delivery coordination unit transmit the data to the automatic control system, compensate and regulate the data in the subsequent new label labeling process, and coordinate the transmission speed of the label 6 and the conveying speed of the labeled product 7. The labeling device 20 can adjust the label length of the label 6 and the label product 7 so as to ensure the accuracy and effectiveness of the labeling process.

[0070] When it is determined that the self-tested gauge length data is inconsistent with the gauge length data in the input parameters and the stop mark position data exceeds the limit range, and the tension data of the label 6 in each state is within the set range, the gauge length intelligent processing unit will first use the label delivery coordination unit to compensate and adjust the header data of the single stop mark position before adjusting through the label delivery coordination unit and the product delivery coordination unit, and the product interval control unit performs auxiliary adjustment, so that the stop mark position of the label 6 at the position of the label picking knife 4 can be within the set range, which can ensure the effectiveness of the label 6 on the labeled product 7 and avoid labeling deviation or The labeling process is carried out in a coordinated manner to ensure that the label is kept in a state of equilibrium and that the label is not adhered to the product 7 due to the label header being too short at the label stop position. This ensures that the product appearance quality is maintained. The label length intelligent processing unit will also generate single label delivery operation data again by controlling the labeling roller group 3 or the label delivery coordination unit after the label stop position is adjusted, and verify the label header data at the label stop position. After the label header data is verified to be valid and within the set range, the label delivery coordination unit and the product delivery coordination unit will coordinately adjust the label length data to promote the accuracy of the subsequent labeling process.

[0071] When it is judged that the self-tested gauge length data is inconsistent with the gauge length data in the input parameters, the stop mark position data exceeds the limit range, and the tension data of the label 6 in each state is outside the limit range, the gauge length intelligent processing unit judges the tension state of the label 6 according to the out-of-limit data. When the tension data in the stop mark state is normal and the tension in the running state is abnormal, the electromagnetic adjustment block in the elastic deformation layer 55 is controlled to generate an electromagnetic effect inside it to perform tension compensation on the label 6. That is, when the label 6 is running, the tension compensation unit is controlled to act on the electromagnetic block at the same time to compensate for the tension of the label 6 in the running state, thereby reducing its transmission jitter and ensuring the precise control of the subsequent gauge length and stop mark position. When the tension data in both the stop mark state and the running state are in an abnormal state, it is directly judged that At this time, the tension adjustment of the label 6 is in an abnormal state, and the control panel 12 is used to remind the technician to adjust it, or when the automatic control system performs automatic tension control through the pneumatic tension roller, the automatic control system automatically adjusts and compensates the tension; when the tension data in the stop state is abnormal and the tension data in the running state is normal, the gauge length intelligent processing unit performs tension compensation on the label 6 in the stop state, and restores the position of the label 6 in the running state, so as to avoid stress damage to the label 6 due to continuous tension compensation. At the same time, the tension compensation in the stop state can ensure the stability of the state when the label 6 is subsequently restarted to be transported, and avoid the deflection, displacement and stacking of the label 6, thereby effectively promoting the control accuracy of labeling;

[0072] Then, after the gauge length intelligent processing unit completes the tension adjustment and compensation under various states of the label 6, it re-judges the gauge length and the stop position. When it is judged that the gauge length and the stop position are still abnormal, the stop position is adjusted first, and then the gauge length is coordinated and adjusted at multiple levels to ensure the high applicability of labeling and products; when it is judged that the gauge length is consistent and the stop position is within the set range data, the parameter data is not adjusted and iterated, and the tension compensation effect of the tension sensing component 5 on the label 6 is maintained during labeling; when it is judged that the gauge length is inconsistent with the set parameters or the stop position exceeds the set range, it is coordinated and adjusted according to the above instructions, and then the parameter data is iterated during the subsequent labeling operation to ensure the automatic regulation of label change and promote label change efficiency and accuracy.

[0073] After the label change is completed, the intelligent processing unit for label length can display the data of label change control to the technicians through the control panel 12, or directly transmit the relevant data to the automatic control system, so that the automatic control system can perform operation control according to the iterated data to ensure the effectiveness of labeling and promote labeling accuracy.

[0074] In the process of continuous automatic labeling, the label head photoelectric sensor 412, the gauge length photoelectric sensor 31, the pressure sensing probe and the infrared sensor can continuously collect the stop position, gauge length, tension data of the label 6 in each state and the full labeling data of the product labeling position in real time, and convert and transmit the full labeling data accordingly through the stop position sensing unit, the gauge length self-test unit, the label feeding tension sensing unit and the product position sensing unit, and transmit it to the gauge length intelligent processing unit. The gauge length intelligent processing unit predicts and judges the error of the label 6 and the labeled product 7 in the labeling process based on the received data, and then, when the labeling error exceeds the labeling range, the gauge length intelligent processing unit passes The error value is analyzed through data analysis. When the analysis shows that the error is accumulated due to the normal operation of the labeling mechanism, the label delivery coordination unit and the product delivery coordination unit coordinate and regulate the relevant data of the label delivery and product delivery to achieve the elimination of the error. In the subsequent continuous operation process, the error elimination and regulation effect can be continuously generated, thereby reducing the probability of poor labeling caused by transmission error. When the error value is analyzed to be caused by tension change, the electromagnetic adjustment block in the elastic deformation layer 55 is further adjusted for its suitability by the tension compensation unit to ensure the stability of the tension of the label 6 in each state, thereby ensuring the accuracy and effectiveness of its labeling.

[0075] After predicting, analyzing, and regulating the labeling error value, the gauge length intelligent processing unit can judge the effectiveness of error value elimination during the subsequent continuous data reception process. After judging that the error value elimination is effective, the parameters after elimination are maintained. When it is judged that the error value elimination is poor, the labeling abnormality is transmitted to the technician through the control panel 12, and the technician is required to manually eliminate it or check and maintain the status of the labeling mechanism and label 6 to ensure the control effectiveness of the subsequent labeling process. When the gauge length intelligent processing unit predicts and analyzes the labeling error value, if the cause of the error value cannot be determined and the error value is large and cannot be regulated, it can also send abnormal signals and alarms to the technician through the control panel 12 to promote the interactive coordination between the labeling mechanism and the technician, promote the emergency efficiency of the technician, and reduce the economic losses caused by continuous poor labeling. While promoting the automation and intelligence level of the labeling mechanism, it can also effectively promote the applicability and economy of the application of the labeling mechanism.

[0076] The third implementation method:

[0077] Figure 1 - Figure 10 The labeling mechanism of the labeling machine is shown. The label length intelligent processing unit includes a label change self-regulating processing module and a labeling operation intelligent processing module. The output end of the label change self-regulating processing module is signal-connected to the labeling operation intelligent processing module. The input ends of the label change self-regulating processing module and the labeling operation intelligent processing module are both connected to the labeling mode recognition switching module. The input end of the labeling mode recognition switching module is also connected to the labeling data acquisition module.

[0078] The output end of the label change self-regulation processing module is connected to the stop position regulation module, the single labeling drive unit, the labeling operation feedback module and the label change abnormal data feedback module. The output end of the stop position regulation module is connected to the single labeling drive unit signal, the output end of the single labeling drive unit is connected to the labeling roller group 3 signal, the output end of the labeling operation feedback module is connected to the automatic control system mounted in the labeling control box 11 signal, and the output end of the label change abnormal data feedback module is connected to the control panel 12 provided on the labeling machine body 1;

[0079] The labeling operation intelligent processing module is signal-connected to the multi-level collaborative compensation module. The output end of the labeling operation intelligent processing module is connected to the labeling error prediction and analysis module and the labeling operation abnormality feedback module. The output end of the labeling error prediction and analysis module is signal-connected to the multi-level collaborative compensation module. The output end of the multi-level collaborative compensation module is signal-connected to the label delivery coordination unit and the product delivery coordination unit respectively. The output end of the labeling operation abnormality feedback module is signal-connected to the control panel 12 provided on the labeling machine body 1.

[0080] The input end of the labeling data acquisition module is respectively connected to the signal of the label length self-test unit, the label stop position sensing unit, the label feeding tension sensing unit and the product position sensing unit. Through the cooperation of the dual operation modes of the label change self-regulation processing module and the labeling operation intelligent processing module, it can realize independent coordination and compensation of the labeling mechanism according to different operation modes, and can also realize autonomous iteration of subsequent labeling data through the coordination of label change data, so as to ensure the accuracy of subsequent labeling operation and the effectiveness of subsequent labeling error prediction and elimination. While reducing the calculation burden and improving the calculation accuracy, it can also effectively ensure the accuracy of labeling operation, so as to ensure the accuracy of subsequent prediction and elimination of labeling errors and realize the self-adaptive compensation of the labeling mechanism.

[0081] Figure 9 and Figure 10 It is shown that the output end of the labeling mode recognition switching module is also connected to a channel direct connection module, and the output end of the channel direct connection module is respectively connected to the label changing self-regulation processing module and the labeling operation intelligent processing module signal, and the input end of the channel direct connection module is respectively connected to the labeling data acquisition module signal. The setting of the channel direct connection module can construct independent data channels for the labeling data acquisition module and the label changing self-regulation processing module and the labeling operation intelligent processing module, and can also realize the automatic switching of the data channel when the mode is switched, reduce the turnover of data transmission, improve the efficiency of data transmission and processing, and improve the efficiency of the multi-level coordination process of label changing and labeling.

[0082] Figure 1 - Figure 10 It shows that when the labeling data acquisition module in the gauge length intelligent processing unit receives and identifies the data transmitted by the operation data acquisition unit and the labeling parameter instruction unit, it can effectively obtain and identify the operating status of the labeling mechanism at this time;

[0083] When it is determined that the labeling mechanism is in the label changing state, the operation mode data is transmitted to the labeling mode recognition switching module, so that the labeling mode recognition switching module controls the label changing self-regulating processing module and the channel direct connection module, prompting the channel direct connection module to connect the data channel between the labeling data acquisition module and the label changing automatic regulating module. The label changing self-regulating processing module can control the single labeling drive unit to start after receiving the data about the replaced label 6 transmitted by the labeling parameter instruction unit according to the receiving effect on the data, and control the labeling roller group 3 to drive the replaced label 6 to perform single transmission regulation. The label changing self-regulating processing module receives the data sent by the labeling data acquisition module. The data transmitted by the label pressure sensing unit and the gauge length self-test unit are used to judge the tension and gauge length data of each operating state of the replaced label 6. When the tension of each operating state of the label 6 is regulated, if the tension data can be compensated, the iterative data is transmitted to the labeling operation intelligent processing module, so that it uses the tension compensation unit to control the electromagnetic adjustment block in the elastic deformation layer 55 to ensure the effectiveness and stability of the tension of each operating state of the label 6. If the tension data exceeds the compensation range, the abnormal data feedback module for label replacement is used to transmit abnormal data to the control panel 12, so that the technician or the automatic control system can regulate the overall tension of the label 6;

[0084] After the tension control or compensation is completed, the label change self-control processing module controls the labeling roller group 3 through the single labeling drive unit to generate a single transmission control for the label 6 again. The label change self-control processing module can receive the data transmitted by the gauge length self-measurement unit, the stop position sensing unit and the label feeding pressure sensing unit through the labeling data acquisition module. First, it is judged that the tension of each state of the label 6 is effective and stable, and then the consistency of the gauge length data and the header margin data of the stop position are judged. When the header margin data of the stop position is not within the set range, the label change self-control processing unit controls the stop position compensation of the single labeling drive unit through the stop position control module. The single labeling drive unit drives the labeling roller group 3 to produce a compensated single transmission control, and then the label change self-control processing module controls and verifies the label head residual data according to the received stop position sensing unit. After judging that the control is effective, the data of the single transmission amount of the labeling roller group 3 at this time is maintained; when the gauge length is inconsistent, the gauge length data and the labeling operation data are controlled, and then the iterative data is transmitted to the labeling operation intelligent processing module, so that it can transmit the iterative data to the automatic control system through the label delivery coordination unit and the product delivery coordination unit, and further coordinated control is performed through the product interval control unit.

[0085] After the label changing self-regulating processing module completes the regulation of the tension, stop position and gauge length coordination data of each state of the label 6, the labeling iteration data is transmitted to the labeling operation intelligent processing module, so that it can iterate and store the data and parameters after the label changing is completed. In addition, the label changing self-regulating processing module can also feed back the operation data after the label changing is completed to the automatic control system through the labeling operation feedback module, so that the automatic control system can operate autonomously or according to the instructions set by the technicians;

[0086] Moreover, when the label changing self-regulating processing module senses and regulates and compensates the tension data, the label stop position data and the label length data, if a persistent abnormality or an invalid regulation state occurs, the abnormal data will be transmitted to the control panel 12 through the label changing abnormal data feedback module. The technicians can make reasonable manual intervention according to the abnormal data and abnormal reminders to avoid the loss of the label 6 or the damage of the labeling mechanism caused by the continuous poor regulation of the label changing.

[0087] After the automatic control system receives the label change completion and labeling operation feedback data transmitted by the labeling operation feedback module or the labeling operation instruction transmitted by the control panel 12, the automatic control system starts and controls the labeling conveying mechanism 2, the conveying guide sleeve 21 and the labeling roller group 3 according to the parameter data after the label change, so as to realize the automatic continuous labeling of the labeled product 7. At the same time, the operation data acquisition unit can receive the labeling operation data of the automatic control system or the labeling parameter instruction unit receives the labeling operation data transmitted by the control panel 12, and transmits it to the labeling mode recognition switching module through the labeling data acquisition module. After the labeling mode recognition switching module recognizes that it is in the labeling mode at this time, it starts the labeling operation intelligent processing module and acts on the channel direct connection module, so that the channel direct connection module can switch and connect the data channel between the labeling data acquisition module and the labeling operation intelligent processing module. The labeling operation intelligent processing module can control the standard distance self-test unit, the stop unit, and the labeling data acquisition module through the labeling data acquisition module. The data transmitted by the labeling position sensing unit, the label feeding tension sensing unit, the operation data acquisition unit and the product position sensing unit are monitored and analyzed, and the labeling operation intelligent processing unit will also transmit the stop position data to the labeling error prediction and analysis module, so that the labeling error prediction and analysis module determines the transmission control error of the label 6 by the labeling roller group 3 according to the change data of the label head margin at the stop position, and then transmits the error data to the multi-level collaborative compensation module. At the same time, the multi-level collaborative compensation module can also receive relevant data about the labeling operation transmitted by the labeling operation intelligent processing module, including but not limited to relevant data such as the label feeding speed, the product feeding speed and the product labeling position. Then, the multi-level collaborative compensation module determines the tension state of the label 6, the state between the label and the product, and the relevant data between the product interval and the label feeding according to the label feeding error data and relevant operation data, effectively determines the factors causing the stop position error, and controls and compensates it according to the factors causing the error, so as to achieve the purpose of eliminating the error;

[0088] When it is determined that the error in the stop position is accumulated due to the control error of the operation of the labeling roller group 3 itself, the compensation data of the labeling roller group 3 transmission control is transmitted to the automatic control system through the label delivery coordination unit, so that the automatic control system can directly act on the labeling roller group 3 and perform error compensation on the operation data of the labeling roller group 3, thereby eliminating the mechanical error of the operation of the labeling roller group 3 itself, while ensuring the label delivery accuracy of the labeling roller group 3, and effectively promoting the effectiveness of the execution of the instructions of the labeling roller group 3 during the subsequent coordinated control. When it is determined that the error is caused by the tension fluctuation of the label 6, the electromagnetic adjustment block in the elastic deformation layer 55 is controlled by the tension compensation unit to realize the self-adaptive tension of the label 6 under various operating states. Force compensation function is used to eliminate the error of the label stop position caused by tension fluctuation, thereby promoting the effectiveness of labeling application; when it is judged that the error is caused by the coordinated action between the labeling conveying mechanism 2 and the labeling roller group 3 or the product interval error, the label delivery coordination unit and the product delivery coordination unit act on the automatic control system to coordinate and compensate the operation between the labeling conveying mechanism 2 and the labeling roller group 3, thereby promoting the effectiveness and accuracy of labeling, and combined with the control of the blocking steering motor by the product interval control unit, the blocking guide roller 22 has the effect of regulating the interval of the product, further promoting the coordinated action of the labeling conveying mechanism 2 and the labeling roller group 3, effectively realizing the elimination of errors, promoting labeling accuracy, and avoiding the problem of label offset;

[0089] After the multi-level collaborative compensation module coordinates and compensates the labeling data, the labeling operation intelligent processing module can verify and judge the data transmitted by the label length self-measuring unit, the label stop position sensing unit, the label feeding tension sensing unit, the operation data acquisition unit and the product position sensing unit through the labeling data acquisition module. When it is judged that the collaborative compensation is effective, the operating parameters at this time are maintained to maintain the accuracy and effectiveness of the subsequent label 6 attached to the labeled product 7;

[0090] The multi-level collaborative compensation module analyzes and judges the error value. When it is judged that the error value is continuously abnormal, the control verification is invalid, or the error value exceeds the control range, it will be fed back to the labeling operation intelligent processing module. The labeling operation intelligent processing module transmits abnormal data and abnormal signals to the control panel 12 through the labeling operation abnormal feedback module, so that technical personnel can make abnormal adjustments and abnormal responses in time to avoid economic losses caused by continuous abnormalities and mechanical damage to the labeling mechanism, and promote the effectiveness and economy of the application of the labeling mechanism.

[0091] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
