Description

Technical Field

[0001] The invention relates to the field of tire vulcanization detection, in particular to an automatic determination method of a tire vulcanization curve. Background Art

[0002] As we all know, the tire vulcanization process is one of the most important processes in tire production. The vulcanization of tires will be affected by factors such as equipment, vulcanization medium, and human factors. Tires with unqualified quality are hereinafter referred to as curve tires. The vulcanization curve generated by the tire during the vulcanization process reflects the quality of tire vulcanization. Among them, temperature, pressure, and time are the three elements for judging whether it is a curve tire. The three elements for judging curve tires can be extended to the instantaneous fluctuation of temperature and pressure, effective external temperature, leak detection sequence, effective and invalid delay, preheating, shaping, condensation removal, stewing pot and other vulcanization curve judgment condition elements.

[0003] The existing PLC industrial control program of the vulcanizer is subject to the characteristics of the PLC industrial control program itself and the influence of the hardware configuration. It can only realize the generation of curve tire single element alarm and shutdown and other actions, while the three curve tire judgment standards of preheating, shaping and decondensation cannot be specifically written in the PLC program of the vulcanizer. The curve generation software that comes with the vulcanizer can only collect the PLC curve data of the vulcanizer to generate curve charts, and there is no function to realize the automatic judgment of tire curve.

[0004] At present, there is no advanced technology for automatic determination of tire vulcanization curve in the tire industry that can be applied to actual production. Determination of curve tires is done manually after the tire is vulcanized, by verifying the tire vulcanization curve on the vulcanizing machine, and then discovering and determining it. As a result, multiple people are required to be responsible for finding tires, verifying curve data, making determination results and subsequent processing. In addition, the search, review and determination of curve tires have a large time lag and may result in errors, mistakes and missed determinations, which brings great risks to the company's product quality control and customer use. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a method for automatically determining the vulcanization curve of a tire, which changes the previous manual grading mode, cooperates with the production and manufacturing system to perform business management and control on vulcanization curve tires, and improves the accuracy and efficiency of curve tire grading.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a method for automatically determining the vulcanization curve of a tire, based on a handheld terminal PDA, a tire barcode, a vulcanizer PLC, a wired network, a server, and a computer client, and characterized in that it includes the following steps:

[0007] Set specific judgment rules for curve tires in the automatic judgment system of tire vulcanization curves. Collect the parameters of the curves generated by the vulcanizer PLC, each single curve element of the vulcanizer, and the alarm parameters. Through the automatic judgment system of tire vulcanization curves, comprehensively analyze the vulcanization alarm parameters and real-time curve data, and cooperate with the specific judgment rules for curve tires set in the automatic judgment system of tire vulcanization curves to make a judgment. Automatically detect curve tires and mark them as frozen at the end of vulcanization. Then, send an instruction to the vulcanizer PLC through the data acquisition software to automatically stop the machine after the mold is opened at the end of vulcanization, and manually intercept the tire. Cooperating with the automated production line and production manufacturing system, it can realize the function of automatically intercepting curve tires in the next process.

[0008] The present invention can also be realized by the following measures:

[0009] The specific judgment rules for curve tires include: converting the range requirements and product performance requirements in tire industry standards and enterprise R & D process standards into production manufacturing standards; according to the production manufacturing standards: based on the actual situation of the factory vulcanizer equipment, select parameters related to tire curve quality to participate in the judgment, and divide the parameters participating in the judgment into alarm parameters that can be detected by the vulcanizer and alarm parameters that cannot be detected by the vulcanizer; the alarm parameters that can be detected: instantaneous fluctuation, effective external temperature, leak detection sequence, effective or ineffective delay, and stewing pot, which are obtained from the vulcanizer PLC using data acquisition software. According to the alarm type, compare with the system curve data, and those exceeding the range are automatically judged as curve tires; the alarm parameters that cannot be detected: parameters such as preheating, shaping, and condensate drainage. The system automatically judges whether it is a curve tire by collecting the real-time parameters of the tire curve of the vulcanization PLC and cooperating with the parameter settings of preheating, shaping, and condensate drainage on the computer client; tires produced in the manual mode of the equipment are all judged as curve tires.

[0010] The automatic judgment rule setting for curve tires on the computer client is set in detail for all tire specifications.

[0011] After the vulcanization is completed and the mold is opened, the automatic tire vulcanization curve tire judgment system collects the curve data of the tire barcode through the intermediate interface in the vulcanizer PLC, and judges whether the tire barcode is a curve tire according to the curve tire judgment standard set by the computer client. If the tire barcode is judged as a curve tire by the automatic tire vulcanization curve tire judgment system, the automatic tire vulcanization curve tire judgment system controls the vulcanizer PLC to perform a shutdown operation through the intermediate interface. The operator checks and repairs the vulcanization equipment and medium. After returning to normal, the handheld terminal PDA performs the startup operation of the vulcanizer to continue normal production. At the same time, the automatic tire vulcanization curve tire judgment system freezes the tire barcode and transmits the judgment result to the production manufacturing system through the intermediate interface to control the automatic transportation line / the next process of the production manufacturing system to automatically intercept the curve tire. After manual review, if the tire meets the upgrade requirements, the handheld terminal PDA can perform the thawing and upgrading operation of the curve tire on the tire barcode. After completion, the tire barcode can perform normal operations in the next process.

[0012] The beneficial effects of the present invention are as follows: it realizes the automatic binding of tire information, vulcanization curve and grading results, improves the accuracy and efficiency of curve tire grading, effectively controls the continuous generation of curve tires, effectively prevents curve tires from entering the next process, improves the overall automation level of the factory, reduces the labor cost of the enterprise and the work intensity of employees, improves the quality of products flowing into the market, and reduces the possibility of safety accidents caused by the quality of product production.

[0017] Set specific judgment rules for curved tires in the automatic judgment system of tire vulcanization curves. Collect the parameters of the curves generated by the vulcanizer PLC, the single curve elements of each vulcanizer, and the alarm parameters. Through the automatic judgment system of tire vulcanization curves, comprehensively analyze the vulcanization alarm parameters and real-time curve data, and cooperate with the specific judgment rules for curved tires set in the automatic judgment system of tire vulcanization curves to make judgments. Automatically detect curved tires and mark them as frozen at the end of vulcanization, and then issue instructions to the vulcanizer PLC through the data acquisition software to automatically stop the machine after the mold is opened at the end of vulcanization, and manually intercept the tires. Cooperating with the automated production line and production manufacturing system, the function of automatically intercepting curved tires in the next process can be realized.

[0018] The specific judgment rules for curved tires include: converting the range requirements and product performance requirements in tire industry standards and enterprise R & D process standards into production and manufacturing standards; according to the production and manufacturing standards: based on the actual situation of the factory vulcanizer equipment, select parameters related to tire curve quality to participate in the judgment, and divide the parameters participating in the judgment into alarm parameters that can be reported by the vulcanizer and alarm parameters that cannot be reported by the vulcanizer; the alarm parameters that can be reported: instantaneous fluctuation, effective external temperature, leak detection sequence, effective and ineffective delay, stewing pot, which are obtained from the vulcanizer PLC using data acquisition software, and according to the alarm type, compare with the system curve data, and those exceeding the range are automatically judged as curved tires; the alarm parameters that cannot be reported: parameters such as preheating, shaping, and condensate drainage, which are automatically judged whether they are curved tires by the system by collecting the real-time parameters of the tire curve of the vulcanization PLC and cooperating with the parameter settings of preheating, shaping, and condensate drainage on the computer client; tires produced in the manual mode of the equipment are all judged as curved tires.

[0019] The setting of the automatic judgment rules for curved tires on the computer client is set in detail for all tire specifications.

[0020] The main functions of the handheld terminal PDA are to scan tire barcodes for production, freeze and thaw curved tires, and control the vulcanizer PLC to resume starting. The main functions of the computer client are to set the judgment criteria for curved tires, display tire curves, query and summarize judgment results, etc.

[0021] Such as Figure 1As shown in the figure, after the vulcanization is completed and the mold is opened, the automatic tire vulcanization curve tire judgment system 3 collects the curve data of the tire barcode 1 through the intermediate interface 8 between the curve tire automatic judgment system and the vulcanizer in the vulcanizer PLC, and judges whether the information of the tire barcode 1 is a curve tire according to the curve tire judgment standard set by the computer client 5; if the information of the tire barcode 1 is judged as a curve tire by the automatic tire vulcanization curve tire judgment system 3, the automatic tire vulcanization curve tire judgment system 3 controls the vulcanizer PLC 4 to start and stop the vulcanizer and manually intercept the curve tire 10 through the intermediate interface 8 between the curve tire automatic judgment system and the vulcanizer. The operator checks and repairs the vulcanization equipment and medium. After returning to normal, the handheld terminal PDA 6 performs the operations of starting and stopping the vulcanizer and manually intercepting the curve tire 10 to continue normal production; at the same time, the automatic tire vulcanization curve tire judgment system 3 will freeze the tire barcode 1 and send the judgment result to the production manufacturing system 2 through the intermediate interface 9 between the production manufacturing system and the curve tire automatic judgment system to control the automatic interception of the curve tire 11 in the automated transportation line / the next process 7 of the production manufacturing system; after manual review, if the tire meets the upgrade requirements, the handheld terminal PDA 6 can perform the curve tire thawing and upgrading operation on the tire barcode 1. After completion, the tire barcode 1 can perform normal operations in the next process.

[0022] The following is a detailed description of the present invention:

[0023] I. Set up a server, deploy data collection software, establish a database, and build a software operation environment;

[0024] II. Write application service programs for the automatic tire vulcanization curve tire judgment system: PDA mobile handheld terminal, computer client;

[0025] PDA mobile handheld terminal: The main functions are to scan the tire barcode for production, freeze and thaw the curve tire, control the vulcanizer PLC to resume startup, etc.;

[0026] Computer client: The main functions are to set curve tire judgment rules, display tire curves, query judgment results, display comprehensive tire information, etc.

[0027] III. Set specific judgment rules for curve tires in the automatic tire vulcanization curve tire judgment system;

[0028] The specific judgment rules for curve tires are to convert the range requirements and product performance requirements in the domestic and foreign tire industry standards and enterprise R & D process standards into enterprise production and manufacturing standards; according to the production and manufacturing standards, based on the actual situation of the factory vulcanizer equipment, the automatic tire vulcanization curve tire judgment system selects the parameters related to the tire curve quality collected by OPL in the vulcanizer PLC to participate in the judgment method.

[0029] The specific judgment rules for the curve tire include: defining constants, obtaining the judgment criteria, monitoring the change value of the value read from the PLC in the OPC, regularly reading the OPC curve address by the program service thread, binding the judgment result after the vulcanizer opens the mold, and issuing a shutdown command to the vulcanizer.

[0030] The defined constants mentioned above are the parameters and names existing in the system, including: the OPC monitoring PLC curve, alarm, status address, judgment criteria record set, curve set value and actual value record, equipment curve and alarm sending address.

[0031] The reading of the judgment criteria refers to the time when the system reads and updates the judgment criteria, and its main parameter is the setting of the judgment criteria reading time.

[0032] The monitoring of the change value of the value read from the PLC in the OPC is to use the data acquisition software OPC to monitor the change of the value in the vulcanizer PLC, including: the manual state of the equipment and the curve alarm record, reading the curve set value, caching the actual value, step number, step time, and collecting other status signals of the machine.

[0033] The program service thread regularly reads the OPC curve address, mainly to collect the parameters in the vulcanizer related to curve judgment, combine the alarm information and the curve tire judgment criteria set in the system to perform curve tire grading, including: determining the alarm content according to the changed address, and retrieving the criteria according to the change value for grading.

[0034] The grading by retrieving the criteria according to the change value includes: the judgment criteria are graded in different ways, and the result after determining the curve tire is written into the system cache record.

[0035] The judgment criteria being graded in different ways means that the parameters participating in the judgment are divided into alarmable parameters of the vulcanizer and non - alarmable parameters of the vulcanizer.

[0036] The alarmable parameters: instantaneous fluctuation, effective external temperature, leak detection step, effective - ineffective delay, stewing pot, etc., are obtained from the vulcanizer PLC by using the data acquisition software OPC, and compared with the system curve data according to the occurrence of the alarm type. Those exceeding the range are automatically determined as curve tires;

[0037] The non - alarmable parameters: parameters such as preheating, shaping, condensate drainage, etc., are automatically determined whether they are curve tires by the system through collecting the real - time parameters of the tire curve of the vulcanization PLC, and cooperating with the curve tire judgment parameter settings of preheating, shaping, condensate drainage on the computer client.

[0038] Tires produced in the manual mode of the equipment are all determined as curve tires.

[0039] In addition, the automatic judgment rule setting of the curve tire on the computer client can be set in detail for all tire specifications.

[0040] After the vulcanizer is opened, the judgment result is bound and a shutdown command is issued to the vulcanizer, and the handheld terminal PDA is used to restore the vulcanizer to normal production operation.

[0041] 4. Write the business processing logic program of the tire vulcanization curve tire automatic judgment system, which mainly focuses on automatic tire curve binding, calling judgment rules, judgment, result storage, command execution, etc. when the curve tire is generated.

[0042] 5. Establish data interface with the PLC system of the vulcanizer to collect curve-related parameters including alarm and machine status information. According to the curve judgment result of the tire by the automatic judgment system of the tire vulcanization curve, call the data acquisition software to issue a command to the PLC of the vulcanizer to shut down the vulcanizer.

[0043] 6. Release the shutdown of the vulcanizing machine through the handheld terminal PDA.

[0044] 7. Establish data interface with the manufacturing system, collect production information of each tire including barcode, specifications, etc., generate and bind the vulcanization curve and judgment result and write it back to the manufacturing system. The manufacturing system will automatically control the interception of tires in the next process according to the judgment result of the tire vulcanization curve, and will not allow the curve tire to proceed to the next process, and generate traceable quality records.

[0045] 8. The specific servers, data acquisition software, databases, software development environments, programming languages, etc. used can be selected based on the company's existing or purchasable equipment.

[0046] 9. The software program can realize the business processing of the entire vulcanization process by expanding its functions.
