[0001] The invention relates to the technical field of tire vulcanizers, and in particular to a vulcanizer processing method and a bladder rupture detection method thereof. Background Art

[0002] Detecting bladder ruptures and leaks in tire curing machines has long been a challenge. There's no reliable way to monitor bladder damage in real time during curing. If a bladder rupture occurs, the curing process will result in the tire being scrapped. If not detected promptly, the bladder could explode, posing a safety hazard.

[0003] If the system cannot automatically detect the phenomenon of bladder rupture and slight leakage in the early stage of the production process, it will cause a large number of scrapped tires; the machine may not stop running until the bladder is completely ruptured, and the cycle time for discovering the fault is long.

[0004] Therefore, it is necessary to improve the existing technology to effectively detect capsule abnormalities in order to improve product yield, reduce equipment losses and improve safety. Summary of the Invention

[0049] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention.

[0051] like Figures 1 to 2 As shown, an embodiment of the present invention provides a method for detecting rupture of a vulcanizing machine bladder, comprising:

[0052] Step A: Real-time collection of humidity data in the vulcanizer;

[0053] Step B: Obtain the current real-time humidity value D1 and perform humidity data analysis;

[0054] Step C: When the current real-time humidity value D1 reaches the humidity warning value, an alarm signal is issued.

[0055] Specifically, first collect the real-time humidity data in the vulcanizer and obtain the current real-time humidity value D1;

[0056] The current real-time humidity value D1 is compared and analyzed. When the humidity warning value is reached, the alarm device in the system will promptly send an alarm signal to remind the staff to stop the current processing operation to avoid capsule rupture or leakage; thereby improving product yield, reducing equipment losses and improving safety.

[0057] In actual use, humidity monitoring can be carried out through a vulcanizer bladder rupture detection system; the vulcanizer bladder rupture detection system specifically includes a humidity sensor device, a bladder rupture detection main control device, and an alarm device.

[0058] In actual operation, the capsule in the vulcanizer is in a vacuum state; a high-temperature resistant humidity sensor is installed on the crossbeam of the vulcanizer to detect humidity changes during the vulcanization process in real time. When the detected humidity data reaches the warning value, a warning is issued and the automatic vulcanization operation of the next tire is stopped.

[0059] When the next stage warning value is reached, the current vulcanization is stopped and an alarm is issued.

[0060] This achieves the following advantages:

[0061] 1. Improve product yield rate, reduce tire scrap rate, and generate direct benefits.

[0062] 2. Improve equipment safety and reduce the risk of capsule explosion.

[0063] Furthermore, step C specifically includes:

[0064] Step C1: When the current real-time humidity value D1 reaches the humidity warning value D4, an alarm signal is issued, and the tire loading device of the vulcanizer is controlled to stop loading the next tire.

[0065] Furthermore, before step C1, the method further includes:

[0066] Step E1: Obtaining the initial humidity value D0 in the vulcanizer;

[0067] Step F1: Calculate the average humidity compensation value D3;

[0068] Step G1: Obtaining a warning deviation preset value D6;

[0069] Step H1: Calculate the humidity warning value D4 = initial humidity value D0 + average humidity compensation value D3 + warning deviation preset value D6.

[0070] In actual operation, after the crossbeam reaches the mold closing limit, the vulcanizer applies the mold closing force and enters the vulcanization process;

[0071] During this period, the capsule rupture detection program runs in real time. When the warning value appears, the equipment will sound an alarm and prohibit the loading of the next tire.

[0072] Furthermore, after step C1, the method further includes:

[0073] Step C2: When the current real-time humidity value D1 reaches the humidity alarm value D5, the vulcanization operation of the current tire is stopped, an alarm signal is issued, and the tire loading device of the vulcanizer is controlled to stop loading the next tire; wherein the humidity alarm value D5 is greater than the humidity warning value D4.

[0074] Furthermore, before step C2, the method further includes:

[0075] Step E2: Obtaining the initial humidity value D0 in the vulcanizer;

[0076] Step F2: Calculate the average humidity compensation value D3;

[0077] Step G2: Obtain the alarm deviation preset value D7;

[0078] Step H2: Calculate the humidity alarm value D5 = initial humidity value D0 + average humidity compensation value D3 + warning deviation preset value D7.

[0079] In addition, during the vulcanization process, when an alarm value appears, the equipment immediately stops the entry of the vulcanization medium, delays the mold opening according to the set time, issues an alarm, and stops loading the next tire.

[0080] Furthermore, in step C2, “stopping the vulcanization operation of the current tire” specifically includes:

[0081] Stop the current tire vulcanization operation and delay mold opening according to the preset time.

[0082] In actual operation, when the alarm value appears, the equipment immediately stops the entry of vulcanizing medium, delays mold opening according to the set time, sounds an alarm, and stops loading the next tire.

[0083] In a specific implementation, when the crossbeam of the vulcanizer is at a set height and vulcanization is in progress, the current real-time value D1 of the sensor is compared with the automatic warning value D4 and the automatic alarm value D5;

[0084] If D1 is greater than D4 or D5, the program executes the exception handling steps. (When the warning value is reached, the equipment issues an alarm and prohibits the loading of the next tire. When the alarm value is reached, the equipment immediately stops the introduction of the curing medium, delays mold opening according to the set time, issues an alarm, and stops the loading of the next tire.)

[0085] Furthermore, in step F1 or step F2, "calculating the average humidity compensation value D3" specifically includes:

[0086] Obtain the maximum humidity peak value D2 during each vulcanization cycle;

[0087] Calculate the humidity difference D9 = maximum humidity peak D2 - current real-time humidity value D1;

[0088] The average value of the 10 humidity difference values ​​D9 is taken as the average humidity compensation value D3.

[0089] In actual operation, the average humidity compensation value D3 is obtained as follows:

[0090] The peak value D2 of each vulcanization cycle minus the current real-time value D1 = the difference value D9 (valid data is taken, alarm data is not applicable), and the average value of 10 difference values ​​D9 = the set compensation value D3.

[0091] Furthermore, before step A, the method further comprises:

[0092] The air blowing solenoid valve is controlled to work and the excess water vapor in the humidity sensor installation barrel 52 is blown away.

[0093] In actual use, after the capsule detection sensor air blowing solenoid valve SV1 is actuated, excess water vapor in the sensor installation barrel 52 can be blown away, making the sensor data more accurate.

[0094] One embodiment of the present invention further provides a vulcanizing machine processing method, comprising the steps of:

[0095] Entering the automatic processing mode, the green tire loading robot 3 automatically loads the tire;

[0096] After the tire is loaded, the mold clamping beam 1 is controlled to descend;

[0097] After the clamping beam 1 reaches the preset height D8, humidity monitoring is performed using any of the above vulcanizer bladder rupture detection methods;

[0098] After the vulcanization process is completed, the maximum humidity peak value D2 during the current vulcanization cycle is sent to the vulcanizer main control PLC for recording.

[0099] Furthermore, “automatic tire loading operation by the green tire loading manipulator 3” specifically includes:

[0100] Control the green tire loading robot 3 to enter the vulcanizer and load the tire on the outer periphery of the bladder;

[0101] After loading is completed, the green tire loading robot 3 is controlled to rotate out of the vulcanizer.

[0102] like Figure 3 As shown, in a specific embodiment, the structural layout of the vulcanizer and its bladder rupture detection system is shown in the figure.

[0103] In a specific embodiment, the specific process of the vulcanizing machine and the bladder rupture detection method is as follows:

[0104] 1. The vulcanizing machine enters automatic mode and performs automatic loading.

[0105] 2. The green tire loading manipulator 3 is transferred into the vulcanizer. At the same time, the air blowing solenoid valve SV1 of the capsule detection sensor is actuated to blow away the excess water vapor in the sensor installation barrel 52, making the sensor data more accurate.

[0106] 3. The robot completes the loading action, the green tire is loaded on the outer side of the bladder, and the robot is transferred out of the vulcanizer.

[0107] 4. The vulcanizer starts the mold closing action (crossbeam descends). When the crossbeam reaches the set height (usually 1000mm from the base), the capsule rupture detection program starts real-time work and monitoring.

[0108] 5. When the crossbeam reaches the mold closing limit, the vulcanizer applies the mold closing force and enters the vulcanization process;

[0109] During this period, the capsule rupture detection program runs in real time. When the warning value appears, the equipment will sound an alarm and prohibit the loading of the next tire.

[0110] When the alarm value appears, the equipment immediately stops the entry of vulcanizing medium, delays mold opening according to the set time, sounds an alarm, and stops loading the next tire.

[0111] 6. After the vulcanizer completes vulcanization, the mold is automatically opened. When the crossbeam rises to the set height (usually 1000mm from the base), the capsule rupture detection program is stopped and the maximum peak value of humidity during this process is recorded in the PLC to facilitate data analysis by the program.

[0112] The main control device in the curing machine bladder rupture detection system can obtain relevant numerical data through the following methods:

[0113] 1. The program starts and the rising edge gets the initial humidity value D0;

[0114] 2. Calculate the average compensation value D3;

[0115] 3. The program calculates the automatic warning value D4 and the automatic alarm value D5 respectively;

[0116] 4. When the crossbeam of the vulcanizer is at the set height and vulcanization is in progress, compare the current real-time value D1 of the sensor with the automatic warning value D4 and the automatic alarm value D5;

[0117] When D1 is greater than D4 or D5, the program executes the exception handling step. (When the warning value is reached, the equipment will sound an alarm and prohibit the loading of the next tire. When the alarm value is reached, the equipment will immediately stop the entry of the vulcanizing medium, delay the mold opening according to the set time, sound an alarm, and stop the loading of the next tire.)

[0118] 5. Vulcanization is completed, and the mold opening and closing beam 1 leaves the set interval, ending the current detection program, and recording the peak data of this humidity cycle for compensation value calculation.

[0119] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation method can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
