Description

Technical Field

[0001] The invention relates to the technical field of tire production and manufacturing, and in particular to a wire ring detection and fool-proofing system and method. Background Art

[0002] The bead wire is a rigid ring made of rubber-coated steel wire arranged in a certain cross-sectional shape. Tire wire refers to the steel wire inlaid on the edge of the rubber tire, and is also called electronic bead wire or tire edge wire. Its function is to give the bead the necessary strength and rigidity so that the tire is firmly fixed on the rim. Its cross-sectional shapes are square, round and hexagonal. The square is mainly used for bias tires and also for radial tires with fiber carcasses, while the round and hexagonal shapes are only used for radial tires.

[0003] The bead wire is a key part of the all-steel radial tire. The bead wire fixes the tire and the rim to support the load, and transmits the drive, brake and torque to the ground. It is located at the intersection of multiple components. Compared with the bias tires of the same specifications, it bears 30% to 50% more additional stress and internal pressure stress. Therefore, strict requirements are imposed on its production process technology, and the support strength must be strong. The bead wire of the all-steel radial tire is made of a single high-extension bead wire. After being attached by the film produced by the extruder, the bead wire is then wound into a coil by the program to form a bead wire with a certain cross-sectional shape. Finally, one or two layers of fiber wrapping cloth are spirally wound on the surface, and after parking, the apex rubber is attached to the tire blank for use.

[0004] In the actual production process, it is easy for the staff to fail to conduct a true self-inspection of the inner diameter and weight of the wire ring or fail to adjust it after measuring and finding that the inner diameter is incorrect, resulting in tire bead quality accidents such as small inner diameter of the wire ring, wrong use of the wire ring, and wrong specification of the wire ring. If the wire ring is scrapped after the tire is formed, it will cause huge losses due to the loss of raw materials. If the inner diameter of the wire ring is not found to be unqualified in time, it will even seriously affect the quality of the tire and cause safety hazards. Guizhou Tire Co., Ltd. has had a total of 11 tire bead quality accidents since 2019, including 8 quality accidents of small inner diameter of the wire ring, wrong use of the wire ring, and wrong specification of the wire ring, accounting for 73%. From January 2020 to April 2024, a total of 241 tires were scrapped due to incorrect inner diameter and specifications of the wire ring, and the total loss of scrapped wire rings and tires was about 330,000 yuan.

[0005] In order to solve the above problems, the inventor team has developed a fool-proof system for detecting the inner diameter and weight of the wire ring to ensure the qualified production of the wire ring, reduce losses caused by raw material loss, and reduce safety hazards. Summary of the invention

[0006] The purpose of the present invention is to provide a fool-proof system for detecting wire rings, so as to prevent employees from forgetting to perform self-inspection on products during production and to prevent specification errors during production.

[0007] A wire ring detection and foolproofing system includes a wire cutting machine, a wire ring measuring instrument, an electronic scale, a quality control system, and an MES, wherein:

[0008] Wire machine, controlled by PLC, for producing wire travellers;

[0009] Wire bead measuring instrument, used to measure the inner diameter of wire bead;

[0010] Electronic scale to measure the weight of the wire ring;

[0011] Quality control systems for traveller production and quality control;

[0012] MES is used for information management of wire machine production.

[0013] The quality control system is communicated with the wire machine, wire ring measuring instrument, and electronic scale. The interface has standard documentation. The MES interface and the PLC interface have standard documentation. The interface has operation data information and log information data, which are uploaded to the MES server. The quality control system writes to the wire machine PLC alarm, specification switching, and whether to use the control signal, which is of int type.

[0014] The functions of the quality control system include obtaining and saving the formula issued by MES, issuing the formula to the wire machine PLC, reading the production quantity of the wire machine, reading the data of the wire ring measuring instrument, reading the measurement data of the electronic scale, associating the read data and integrating and packaging and uploading it to MES, spot inspection timeout alarm, spot inspection reminder and electronic scale weight out-of-tolerance alarm.

[0015] The formula issued by the MES includes specification code, wire ring inner diameter standard, wire ring weight standard, inspection frequency information, and the maximum quantity allowed to be produced when the inspection fails.

[0016] The inspection timeout alarm includes a recipe switching inspection timeout alarm and a normal production quantitative inspection timeout alarm.

[0017] The normal production quantitative inspection timeout alarm is set, and each production group A needs to be inspected; when the electronic scale has new data, read the data of the wire ring measuring instrument, compare these data with the formula, and only when the weight and diameter are qualified are they considered qualified, and the test results are sent to the PLC; after each production of group A, if there is no test result, the system will issue an inspection timeout alarm.

[0018] The switching formula inspection timeout alarm is set, and the number B to be inspected is set. After the inspection is qualified, the normal production process is entered; it is set that unqualified groups are allowed to produce C groups, and only group C is allowed to be produced if unqualified. At least one group of this C group must be inspected, and if it fails again, group C is still allowed to be produced, and the cycle continues until it is qualified or a new formula is switched. If the formula is switched without inspection or there is no test result of at least one group after each production of group C, the system will issue an inspection timeout alarm.

[0019] The inspection reminder reminds the operator to inspect when setting the remaining D groups for production.

[0020] Another object of the present invention is to provide a method for using a wire ring detection foolproofing system, comprising the following steps:

[0021] S10 connects the quality control system with the wire machine, wire machine measuring instrument, and electronic scale, and uploads them to MES;

[0022] S20 MES sends the formula to the quality control system. The quality control system keeps a backup copy in the local software and then sends it to the corresponding wire machine PLC. The alarm and specification switching signals are int type. The PLC also decides whether to use the production control function of the quality control system based on the int signal. 0 is not used, 1 is used. Finally, production is carried out.

[0023] The S30 quality control system reads the number of wire rings produced by the wire machine, the weight of the wire rings measured by the electronic scale, and the diameter of the wire ring measured by the wire ring measuring instrument. The electronic scale is a manual electronic weighing scale.

[0024] S40 associates the data read by S20 to realize timeout alarm and inspection reminder for switching between recipe inspection and normal production quantitative inspection;

[0025] S50 associates the data read by S20, packages it and uploads it to MES.

[0026] The electronic scale weight out-of-tolerance alarm comprises the following steps:

[0027] S41 If MES issues a recipe, the local recipe is updated, there is a local standard data, the latest production specifications are obtained through PLC, and the corresponding recipe is called;

[0028] S42 keeps reading the data of the manual electronic weighing scale. If the data is not 0 and does not jump for three consecutive times, the data is intercepted. At this time, the number of wire rings that can be produced is limited to not more than the maximum amount allowed to be produced when the inspection fails. The maximum amount is set by the recipe;

[0029] The S43 quality control system reads the diameter data measured by the wire ring, the weighing data of the electronic scale, and the output data of the wire machine;

[0030] The data read by S44 is compared with the standard data in the formula. If the weighing data of the electronic scale is within the standard range, a qualified signal is sent to the corresponding steel wire machine, and the steel wire machine can continue to produce. If it exceeds the standard range, an unqualified signal is sent to the corresponding steel wire machine, and the steel wire machine can be re-inspected according to the maximum amount allowed to be produced when the spot inspection fails. If the re-inspection is qualified, a qualified signal is sent to the corresponding steel wire machine, and the steel wire machine can continue to produce; if the re-inspection fails, production is stopped;

[0031] S45 loops through steps S41 to S44.

[0032] Beneficial effects:

[0033] 1. The wire ring detection and fool-proofing system is connected to the wire ring electronic weighing data, wire ring diameter measuring instrument data, wire machine PLC data, and MES data, which is convenient for data collection and information processing. After the MES switches the specifications, the software automatically updates all parameters without manual intervention, and the degree of automation is high.

[0034] 2. The bead ring detection and fool-proofing system reminds employees to perform inspections, thereby reducing tire bead ring quality accidents caused by forgetting to perform inspections, reducing bead ring losses, and reducing tire scrap rates.

[0035] 3. The wire ring detection fool-proof system automatically checks the wire ring production specifications, weight, and diameter parameters, reducing manual participation and improving the accuracy of wire ring detection.

[0036] 4. Reduce the scrapping of wire rings and tires due to incorrect inner diameter and specifications of the wire rings. Compared with production without using the wire ring detection and fool-proofing system of the present invention, 186.12 kg of raw materials can be saved due to scrapping for every 2000 hours of production, saving costs of 1525.664 yuan.

[0118] In order to verify whether the wire bead detection fool-proofing system can effectively reduce tire bead quality accidents caused by incorrect specifications or failure to self-check, and to evaluate the impact of the new system's improved automation on production efficiency, the research team designed a comparative test, the specific excerpts are as follows:

[0119] 1 Experimental Grouping

[0120] Test group: using the system and method for production, specifically, the wire ring detection fool-proofing system is as in Example 1, and the method steps are as in Example 3.

[0121] Control group: Using the traditional method, i.e. manual measurement and record keeping and manual adjustment for production, when employees switch production specifications, they need to measure the inner diameter and weight of two wire rings by themselves and make paper records.

[0122] 2. Test process

[0123] The test cycle is set to one quarter, starting from September 1, 2023 to December 31, 2023, to ensure that the two groups of personnel and equipment have consistent production conditions. The production method is used as the independent variable, and the tire bead quality accident data, production volume, and raw material loss data of the two groups are collected for comparative analysis.

[0124] 3 Results

[0125] After one quarter of production, the data recorded are shown in Table 1.

[0126] Table 1 Comparison of production data

[0127]

[0128] The production efficiency is calculated according to the following formula:

[0129]

[0130] The product qualification rate is calculated according to the following formula:

[0131]

[0132] The cost of raw material loss is calculated according to the following formula:

[0133] Raw material loss cost = loss amount * unit cost

[0134] The results are shown in Table 2.

[0135] Table 2 Comparison of statistical results

[0136]

[0137] The results show that the production efficiency and production qualification rate of the test group are higher than those of the control group, and the raw material loss is lower than that of the control group. It can be seen that the present invention can significantly reduce the tire bead quality accident rate, especially the specification error problem, and improve the production efficiency, reduce the raw material loss, and reduce the production cost.

At least one group of this C group must be inspected, and if it fails again, group C is still allowed to be produced, and the cycle continues until it is qualified or a new formula is switched. If the formula is switched without inspection or there is no test result of at least one group after each production of group C, the system will issue an inspection timeout alarm.

8. The wire ring detection fool-proofing system according to claim 3, characterized in that: The inspection reminder reminds the operator to inspect when setting the remaining D groups for production.

9. A method for using a wire ring detection foolproofing system, characterized in that: The steps include: S10 connects the quality control system with the wire machine, wire ring measuring instrument, and electronic scale, and uploads them to MES; S20 MES sends the formula to the quality control system. The quality control system keeps a backup copy in the local software and then sends it to the corresponding wire machine PLC. The alarm and specification switching signals are int type. The PLC also decides whether to use the production control function of the quality control system based on the int signal. 0 is not used, 1 is used. Finally, production is carried out. The S30 quality control system reads the number of wire rings produced by the wire machine, the weight of the wire rings measured by the electronic scale, and the diameter of the wire rings measured by the wire ring measuring instrument; S40 associates the data read by S2 to switch the recipe to check the wire ring diameter and wire ring weight, and to implement the normal production quantitative inspection warning and timeout alarm shutdown; S50 associates the data read by S2, packages it and uploads it to MES.

10. The method for using the wire ring detection foolproofing system according to claim 9, characterized in that: The electronic scale weight out-of-tolerance alarm comprises the following steps: S41 If MES issues a recipe, the local recipe is updated, there is a local standard data, the latest production specifications are obtained through PLC, and the corresponding recipe is called; S42 keeps reading the weighing data of the electronic scale. If the data is not 0 and does not jump for three consecutive times, the data is intercepted. At this time, the number of wire rings that can be produced is limited to not more than the maximum amount allowed to be produced when the inspection fails. The maximum amount is set by the recipe; The S43 quality control system reads the diameter data measured by the wire ring, the weighing data of the electronic scale, and the output data of the wire machine; The data read by S44 is compared with the standard data in the formula. If the weighing data of the electronic scale is within the standard range, a qualified signal is sent to the corresponding steel wire machine, and the steel wire machine can continue to produce. If it exceeds the standard range, an unqualified signal is sent to the corresponding steel wire machine, and the steel wire machine can be re-inspected according to the maximum amount allowed to be produced when the spot inspection fails. If the re-inspection is qualified, a qualified signal is sent to the corresponding steel wire machine, and the steel wire machine can continue to produce; if the re-inspection fails, production is stopped; S45 loops through steps S41 to S44.
