Description

Technical Field

[0001] This invention relates to the field of automated tire production technology, and in particular to a control method and system for automatically uploading tire winding output. Background Technology

[0002] Currently, in the tire industry's production process, output statistics, production data traceability, production scheduling, and quality control at the winding stage are all done manually. This leads to significant inaccuracies in capacity and inventory data. This is because production output is directly linked to operator wages, and some operators inflate production figures, resulting in artificially high inventory levels. Therefore, production data traceability is necessary to confirm inventory levels and enable reasonable production scheduling. However, the existing manufacturing process cannot trace and confirm inventory based on production data, leading to persistent uncertainty in inventory levels and causing significant disruptions to production scheduling. This results in shortages and surpluses of many material specifications.

[0003] Traditional methods rely on manual recording of the number of meters or rolls wound and manual input into the MES system or other production management systems. This results in problems such as low efficiency, easy errors, and data lag. It is also impossible to accurately bind the data with the tooling, making it difficult to adapt to the needs of intelligent production.

[0004] To gradually realize Industry 4.0 digital factories, and to better monitor and improve product quality, achieve production process control, and reduce fluctuations in product quality and batch quality accidents caused by manual adjustment of equipment parameters, the output statistics and production data traceability of the winding process are crucial for production scheduling and quality control. Existing equipment production automation solutions mostly focus on single data acquisition, lacking deep collaboration among multiple systems such as MES, PLC, and RFID, and cannot achieve closed-loop management of the entire process of production tasks, tooling signals, and winding meters. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the above-mentioned technologies and provide a control method and system for automatically uploading tire winding output.

[0006] Therefore, the present invention provides a control method for automatically uploading tire winding production, comprising the following steps:

[0007] S1. The MES system receives production planning tasks, parses tire parameters, automatically switches production specifications, and sends production task instructions to the PLC system.

[0008] S2 and PLC systems detect in real time whether there are toolings at the winding station. Once the toolings are in place, the arrival signal is transmitted to the MES system.

[0009] After receiving the bit signal, the S3 and MES systems read the chip barcode on the tooling and transmit it to the PLC system and MES system. The MES system assigns the barcode to the corresponding winding station partition according to the station number of the currently received bit signal, and then verifies the validity of the chip barcode.

[0010] S4. After the verification is successful, the MES system sends the barcode information to the PLC system. The PLC system matches the sent barcode information with the locally synchronized original RFID barcode and workstation number. Production begins after the match is correct.

[0011] S5. During production, the meter counting device collects the number of rolls in real time and uploads it to the PLC system. When the number of rolls reaches the preset value of the MES system and the tooling leaves the roll station, the PLC system triggers the production completion signal simultaneously and uploads it to the MES system along with the number of rolls. The MES system associates and binds the barcode with the number of rolls, tire specifications, production time, and station number to generate production records and update production statistics.

[0012] After receiving the data uploaded by the PLC system, the S6 MES system sends a zeroing command to the PLC system. The PLC system then zeros the completion signal and the winding length, and sends a zeroing completion signal back to the MES system.

[0013] S7. The next process scans the chip barcode on the tooling using the RFID system, and the MES system retrieves and displays the corresponding production record.

[0014] Preferably, the barcode information issued in step S4 includes the standard barcode digits, barcode string, and workstation number. The PLC system confirms the correctness of the barcode information through a three-level progressive logic judgment, including:

[0015] First layer: The PLC system extracts the actual character length of the original RFID barcode from the local cache, compares the actual character length with the standard barcode length issued by the MES system, and if the lengths match, proceeds to the second layer of content comparison;

[0016] The second layer: The PLC system compares the locally cached original RFID barcode with the complete barcode string issued by the MES system character by character. After all characters match correctly, it enters the third layer of workstation binding verification.

[0017] The third layer: The PLC system reads the station code of the current winding station, compares the extracted station number with the station number issued by the MES system, and if the numbers match, all are correctly matched and the process enters the production process.

[0018] Preferably, if any layer of the PLC system encounters a matching error, the judgment process terminates, the cause of the fault is uploaded to the MES system, the MES system displays a pop-up window showing the cause of the fault and activates an audible and visual alarm, and switches to the manual intervention process.

[0019] Preferably, in step S3, the validity verification includes judging at least one of the following: the number of bits, the prefix, the check bit, and the number of reads of the chip barcode.

[0020] Preferably, when the MES system receives the position signal and the RFID-uploaded barcode, it marks them with timestamps and sets a time matching window. Only when the timestamp of the RFID barcode falls within the time window interval corresponding to the position signal will the MES system determine that the barcode is a valid barcode for this workstation and perform validity verification. RFID barcodes with mismatched timing are directly filtered out without validity verification.

[0021] Preferably, after receiving the data uploaded by the PLC system, the MES system first checks whether there is a duplicate production record; if it exists, the production is not added again, but only the upload status and / or abnormal status are updated; if it does not exist, a new production record is created and the production statistics are added.

[0022] Preferably, the PLC system latches the actual meter reading and completion sequence number before uploading. The completion sequence number is arranged according to the order of completion signals, and the actual meter reading and completion signal are not overwritten before the zeroing instruction returned by the MES system is received.

[0023] Preferably, when communication between the PLC system and the MES system is interrupted, the PLC system writes the actual meter reading and completion sequence number into a local buffer queue and retransmits them after communication is restored.

[0024] This invention also provides a control system for automatically uploading tire winding production, including a MES system, a PLC system, an RFID system, a metering device, and a tooling status detection device. The MES system is used to receive and parse production plan tasks, realize production specification switching, issue production task instructions, generate production records by deduplication, send zeroing instructions, and provide traceability queries. The PLC system is used to receive production task instructions issued by the MES system, collect tooling status and metering data, latch the completion sequence number and actual meter count, and perform zeroing. The RFID system is used to read the tooling chip barcode and send the barcode to the MES system and / or the PLC system. The metering device is used to collect the winding meter count in real time and transmit the winding value signal to the PLC system. The tooling status detection device is connected to the PLC system and is used to detect the tooling in place, out of place, or winding status and upload the above status to the PLC system.

[0025] This invention provides a control method and system for automatically uploading tire winding output, which has the following beneficial effects.

[0026] (1) Deep collaboration of multiple systems including MES, PLC and RFID covers the entire process from production task assignment, tooling identification, data collection to output upload, replacing manual operation, greatly improving production efficiency and reducing human error rate;

[0027] (2) Bind the tool barcode to data such as winding length and tire specifications to build accurate production records and provide reliable data support for quality traceability and process optimization;

[0028] (3) By interacting with the zeroing signal, the closed loop of single production data is completed, ensuring that the output statistics are accurate in real time and helping to make precise decisions on production scheduling;

[0029] (4) The next process scans the code to retrieve the data of the whole process, breaks down the data barrier in the production process, and improves the efficiency of quality control and problem tracing. Attached Figure Description

[0030] Figure 1 This is a flowchart of the control method for automatically uploading tire winding production;

[0031] Figure 2 This is a schematic diagram of the control system for automatically uploading tire winding output. Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0033] like Figures 1-2 As shown, the present invention provides a control method for automatically uploading tire winding output, comprising the following steps:

[0034] S1. The MES system receives production planning tasks, parses tire parameters (including tire specifications, output, preset winding length, etc.), automatically switches production specifications, and sends production task instructions to the PLC system.

[0035] The S2 and PLC systems monitor the winding station in real time to detect whether there are tooling fixtures. When the tooling fixtures are detected to be in place, the system sends an arrival signal to the MES system to trigger subsequent processes. If the tooling fixtures are not detected to be in place, the system continuously monitors and sends the status back to the MES system for early warning.

[0036] After receiving the bit signal, the S3 and MES systems receive the chip barcode on the tooling read by the RFID system. The MES system assigns the barcode to the corresponding internal winding station partition based on the station number of the received bit signal, and then verifies the validity of the chip barcode. The chip barcode read by the RFID system is transmitted to both the PLC system and the MES system.

[0037] In some other preferred embodiments, since multiple winding stations in the workshop are working simultaneously, readers are prone to cross-station reading. When the MES system receives the bit signal and the barcode uploaded by the RFID system, it marks the timestamps and sets a time matching window. When the timestamp of the RFID barcode read falls within the time window interval corresponding to the bit signal, the MES system determines that the barcode is a valid barcode for this station and performs validity verification. RFID barcodes with mismatched timing are directly filtered out without validity verification, effectively avoiding barcode misassignment caused by signal crosstalk between adjacent stations.

[0038] The duration of the time matching window is set according to the RFID reader response delay and the tooling arrival stabilization time, preferably 500ms to 2000ms, and this duration can be adjusted online by on-site maintenance personnel through the MES system interface.

[0039] When multiple winding station fixtures arrive at the same time, the MES system assigns the barcode to the winding station with the matching timestamp based on the aforementioned time matching window mechanism.

[0040] In some other preferred embodiments, validity verification includes determining at least one of the following: the number of bits, the prefix, the check bit, and the number of reads of the chip barcode.

[0041] S4. After verification, the MES system sends the barcode information to the PLC system. The PLC system matches the sent barcode information with the locally stored original RFID barcode and workstation number. Once the match is correct, production begins.

[0042] The RFID system consists of readers installed at the winding station and RFID chips mounted on the tooling. The readers communicate with the PLC system via Ethernet / serial port / near-field direct connection, etc. After reading the card, the original barcode is uploaded to the PLC system in real time and cached in the PLC system's local register. Simultaneously, the original barcode also communicates with the MES system via Ethernet / wireless / JSON, etc., with different transmission links between the two. When the RFID barcodes received by the MES system have problems such as transmission transcoding errors, incompleteness, or loss, most errors can be detected in the MES system's primary verification. However, for some detailed transcoding errors, such as the reader being interfered with by the frequency converter and transcoding "Tyre_20250101_001" into "Tyre_20250102_001" (both barcodes have the same number of bits), the MES system's primary verification will pass directly. If a secondary verification by the PLC system is not set up, this erroneous data will directly flow into the production process, leading to errors in subsequent output and quality traceability.

[0043] In some other preferred embodiments, the barcode information issued by the MES system includes the standard barcode digits, barcode string, and workstation number. The PLC system confirms the correctness of the barcode information through a three-layer progressive logic judgment, including:

[0044] First layer (digit verification): The PLC system uses the character length acquisition instruction to extract the actual character length of the RFID raw barcode in the local cache, and compares the actual character length with the standard barcode digit length issued by the MES system. If the digit lengths match, it proceeds to the second layer of content comparison.

[0045] The second layer (content verification): The PLC system compares the locally cached original RFID barcode with the complete barcode string issued by the MES system character by character using string equality comparison instructions. After all characters match correctly, it enters the third layer of workstation binding verification.

[0046] The third layer (station verification): The PLC system reads the station code of the current winding station, compares the extracted station number with the station number issued by the MES system, and if the numbers match, all are correctly matched and the process enters the production process.

[0047] If any layer of the PLC system encounters a matching error, the judgment process terminates, and the cause of the fault is uploaded to the MES system. The MES system displays a pop-up window showing the cause of the fault and activates an audible and visual alarm, switching to the manual intervention process. The manual intervention process includes manually re-entering barcodes or inspecting RFID readers, tooling chips, etc.

[0048] The MES system only allows the PLC system to perform the winding operation after the chip barcode verification is successful and the PLC system's secondary verification is correct. If the chip barcode verification fails, the tooling is not in place, or the secondary verification fails, the PLC system will prohibit the start of the winding equipment and output alarm information.

[0049] The MES system first verifies the validity of the chip barcode by checking the number of bits, prefix, and check digit. After the verification is successful, the PLC system performs a second verification through a three-layer progressive logic judgment (number of bits - content - workstation). If any layer fails to match, the judgment will terminate and an alarm will be triggered. This avoids problems such as network transmission packet loss, signal distortion, and transcoding errors that can occur with single verification in the MES system, and effectively prevents production attribution errors caused by barcode reading errors or mixed tooling.

[0050] S5. During production, the meter counting device collects the number of rolls in real time and uploads it to the PLC system. When the number of rolls reaches the preset value of the MES system and the tooling leaves the roll station, the PLC system triggers a production completion signal simultaneously, which is uploaded to the MES system along with the number of rolls. The MES system associates and binds the barcode with the number of rolls, tire specifications, production time, and station number, generates production records, and updates production statistics.

[0051] After receiving the data uploaded by the PLC system, the S6 MES system sends a zeroing command to the PLC system. The PLC system then zeros the completion signal and the winding length, and sends a zeroing completion signal back to the MES system. The completion sequence number count within the PLC system is unaffected by this zeroing command and continues to accumulate, ready to be assigned a new completion sequence number for the next roll production.

[0052] In some other preferred embodiments, after receiving the data uploaded by the PLC system, the MES system first checks whether there is a duplicate production record. If it exists, the production is not added again, but only the upload status and / or abnormal status are updated. If it does not exist, a new production record is created and the production statistics are added, which effectively prevents duplicate production counting caused by network jitter or system abnormalities.

[0053] Specifically, the MES system establishes a unique index consisting of "corresponding winding station number + RFID chip barcode + single roll completion production time (accurate to the second)". Only one production record can exist for the same set of tooling, the same station, and the same production period. After receiving the data packet uploaded by the PLC system, the MES system searches the database using this combination of conditions. If a duplicate record exists, the production record is not updated; only the data upload status is refreshed (e.g., "synchronized") and the communication error log is marked. If no duplicate record exists, it is determined to be the first upload, a new production record file is created, and the total production record is increased.

[0054] In some other preferred embodiments, the PLC system latches the actual meter reading and the completion sequence number before uploading. The completion sequence number is arranged according to the order of the completion signals, and the actual meter reading and completion signals are not overwritten before the zeroing instruction returned by the MES system is received.

[0055] In some other preferred embodiments, when communication between the PLC system and the MES system is interrupted, the PLC system writes the actual meter reading and completion sequence number into a local cache queue and retransmits them after communication is restored, ensuring that the data is not lost and guaranteeing the integrity and timing consistency of the production data.

[0056] Specifically, the PLC system sets up an independent buffer for each winding station. The completion sequence number, winding length, and barcode information of each station are locked separately according to the station number, without interference between them.

[0057] The MES system performs a second deduplication check on the retransmitted data from the PLC system. If a valid production record already exists for the completion number, the system only updates the PLC communication status to "synchronized" and does not write the production statistics again.

[0058] S7. The next process scans the chip barcode on the tooling using the RFID system, and the MES system retrieves and displays the corresponding production record.

[0059] like Figure 2As shown, the present invention also provides a control system for automatically uploading tire winding output, including an MES system, a PLC system, an RFID system, a metering device, and a tooling status detection device.

[0060] The MES system is deployed on a workshop-level server to receive and parse production planning tasks, enabling production specification switching, issuing production task instructions, receiving tooling arrival signals, verifying chip barcodes, deduplicating and generating production records, sending zeroing instructions, synchronously updating production statistics, and providing a data query interface to support traceability queries.

[0061] The PLC system is deployed at the winding equipment site to receive production task instructions from the MES system, collect tooling status and metering data, latch the completion sequence number and actual meter count, and perform zeroing.

[0062] The RFID system includes a reader / writer installed at the winding station and an RFID chip installed on the tooling, used to read the barcode on the tooling chip and simultaneously send the barcode to the MES system and PLC system.

[0063] A meter-counting device is installed at the winding station to collect the winding length in real time and transmit the winding value signal to the PLC system. The meter-counting device includes a meter-counting wheel and an encoder. The encoder is coaxially connected to the meter-counting wheel via a coupling, converting the rotational displacement of the wheel into a continuous pulse signal.

[0064] The tooling status detection device (preferably a photoelectric switch) is installed at the winding station and connected to the PLC system. It is used to detect the tooling in place, out of place, or winding status and upload the above status to the PLC system.

[0065] The MES system, PLC system, RFID system, metering device, and tooling status detection device interact with each other via Ethernet and other means.

[0066] This invention eliminates the need for manual input or confirmation throughout the entire process, from production planning and task issuance, tooling arrival and inspection, barcode reading and verification, winding production to output record generation and uploading. It fundamentally avoids the data lag and error risks caused by manual recording, provides a true and reliable data foundation for inventory accounting and production scheduling, effectively avoids inventory distortion caused by manual false reporting, and significantly improves production efficiency.

[0067] Example 1:

[0068] like Figure 1 As shown, the present invention provides a control method for automatically uploading tire winding output, which is applied to the tire winding station.

[0069] Taking the radial tire winding process as an example, the above control method includes the following steps:

[0070] The S1 and MES systems receive production planning tasks that include tire specifications (e.g., 205 / 55R16) and production volume (100 rolls). The preset winding length is set to 200 meters. The winding parameters are automatically switched, and production task instructions are sent to the PLC system via OPC, XLP, JSON, etc.

[0071] The S2 and PLC systems use a tooling status detection device (photoelectric switch) to detect in real time whether there is a tooling at the winding station. When the tooling is detected to be in place, the system sends the arrival signal to the MES system.

[0072] After receiving the bit signal, the S3 and MES systems receive the chip barcode (such as the code "Tyre_20250101_001") read by the RFID system on the tooling and transmit it to the PLC system and the MES system respectively. The MES system assigns the barcode to the corresponding winding station partition within its internal system according to the station number (such as "A01") of the currently received bit signal.

[0073] The MES system compares the number of bits in the chip barcode with the preset standard encoding number of bits (such as 17 bits) for the corresponding winding station partition. After the verification is successful, the standard barcode number of bits (17 bits), the barcode string (Tyre_20250101_001), and the station number (A01) are sent to the PLC system. The PLC system then compares the standard barcode number of bits (17 bits), the barcode string (Tyre_20250101_001), and the station number (A01) with the original RFID barcode cached locally and the station code (A01) of the current winding station. If the comparison is consistent, the system proceeds to the production process.

[0074] S5. During production, the meter counting device collects the number of rolls in real time and uploads it to the PLC system. The PLC system compares the current number of rolls with the preset 200 meters in real time. When the counted number of rolls reaches the preset 200 meters in the MES system, the tooling leaves the winding station. The PLC system simultaneously triggers a production completion signal, which is uploaded to the MES system along with the actual number of rolls (200 meters). The MES system associates and binds the barcode (Tyre_20250101_001) with the number of rolls (200 meters), tire specification (205 / 55R16), production time, and station number (A01) to generate a production record. The cumulative production in the MES system is updated to 1 roll.

[0075] After receiving the data uploaded by the PLC system, the S6 MES system sends a zeroing command to the PLC system. Upon receiving the command, the PLC system zeros the completion signal and the winding length, and sends a zeroing completion signal back to the MES system. The winding output upload loop for this round is now complete.

[0076] S7. When the next process uses the material of this specification, the chip barcode on the tooling is scanned by the RFID system. The MES system displays information such as "winding length 200 meters, specification 205 / 55R16, machine A01" to achieve data traceability.

[0077] Example 2:

[0078] In a workshop with multiple winding machines operating in parallel, when workstations are close together, RFID readers may read chip barcodes on adjacent workstation fixtures due to signal crosstalk. To solve this problem, this invention incorporates a time-matching window mechanism into the MES system.

[0079] When the MES system receives a tooling arrival signal from the PLC system, it records the first timestamp T1 (arrival time). When the MES system receives barcode information from the RFID system, it records the second timestamp T2 (barcode reading time). The time matching window is set to 1000ms.

[0080] When T1 is 10:00 and T2 is 10:00:005, if the barcode reading time falls within the 1000ms window (10:00-10:00:01) after the arrival signal, the MES system determines that the barcode is a valid barcode for this workstation and enters the validity verification process.

[0081] When T2 is 10:00:02, the barcode reading time is not within the window after the arrival signal (it may be a barcode from an adjacent workstation or a historical residual barcode). The MES system directly filters the barcode information and does not perform validity verification.

[0082] The duration of this time matching window can be adjusted online by on-site maintenance personnel through the MES system interface to adapt to the differences in response speed of different RFID readers and the stable arrival time of tooling.

[0083] Example 3:

[0084] If the upload link between the PLC system and the MES system is interrupted during production, the PLC system will be unable to upload the production completion data to the MES system in real time. The PLC system will write the actual meter reading and completion sequence number latched at the corresponding workstation into its local dedicated buffer queue and retransmit them after communication is restored.

[0085] Specifically, upon completion of each winding operation, the PLC system assigns a new completion sequence number (incrementing sequentially, such as 001, 002, 003, etc.) and latches the actual length of the winding, barcode information, and completion sequence number. If a communication interruption with the MES system is detected, the PLC system writes the aforementioned data to its local corresponding buffer queue and continuously monitors the communication status.

[0086] Once communication is restored, the PLC system retransmits the data in the buffer queue to the MES system. Upon receiving the retransmitted data, the MES system first checks if a valid production record already exists for that completion number. If it does, it only updates the PLC communication status to "synchronized" and does not write the production statistics again, avoiding the same roll's production being counted twice due to network interruptions, resulting in inflated production statistics. If it does not exist, it creates a new production record and updates the production statistics.

[0087] It should be noted that the completion number counter inside the PLC system is an independent register, which is not affected by the clear instruction in step S6, and always increments sequentially by volume.

[0088] This invention constructs an automatic upload control system for tire winding production through multi-system collaboration, which is adapted to the needs of intelligent tire manufacturing and can be extended to various tire production scenarios. Practical verification shows that the accuracy of production data is improved to 99.9%, and the rate of manual intervention is reduced by 70%, demonstrating significant application value.

[0089] In the description of this invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0090] However, the above description is merely a specific embodiment of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of the present invention should still fall within the scope of the claims of the present invention.

The RFID system reads the tooling chip barcode and sends the barcode to the MES system and / or PLC system. The metering device collects the winding meter count in real time and transmits the winding value signal to the PLC system. The tooling status detection device is connected to the PLC system and is used to detect the tooling's position, departure, or winding status and upload the above status to the PLC system.
