Description

Technical Field

[0001] The present application relates to the technical field of tire molding, and more specifically, to a tire cord joint avoidance device. Background Art

[0002] Tires are an essential and important component of automobiles. The dynamic and static balance and uniformity of tires affect the feel and safety of automobiles. In the production process of tires, the whole roll of cord used in the molding process is made of cord produced in the semi-finished product process by cutting and splicing. There are usually two joints, a molding joint at the molding joint and a semi-finished product joint at the semi-finished product joint. At present, during tire production, the equipment only locates the molding joint according to the process parameters, and lacks the detection and positioning of the semi-finished product joint position, resulting in the overlap of the semi-finished product joint with the molding joint and other semi-finished product joints. Since the material thickness of the joint overlap part is different from that of the rest of the cord, the expansion rate of this part after the finished tire is inflated is inconsistent with other parts, which will cause bumps and bumps compared to other parts, affecting the uniformity and dynamic and static balance of the tire, causing the car to bump up and down and generate noise during driving, posing certain safety hazards. Tire joints are unavoidable in the production process, and there is an urgent need for a device that can effectively detect different joint positions and disperse and avoid them to solve the problem of bumps and bumps on the tire sidewall.

[0003] In response to the existing problems, a Chinese patent with application number CN202021851680.5 discloses a tire material joint distribution measuring disk, including an angle dial, on which an angle scale is provided, and a number of pointer parts are rotatably connected to the angle dial. According to the standard dispersion angle of the tire material joints, each pointer part corresponds to a tire material joint, and the measuring disk is placed at the center of the tire to measure whether the distribution position of each material joint on the tire is the same as the angle indicated by the corresponding pointer part. If there is a difference, the position of the corresponding tire material joint is adjusted. This technical solution facilitates the measurement of the distribution positions of multiple tire material joints, which is beneficial to the accuracy of the position of the tire measurement joint. However, the above technical solution requires manual preset of the standard distribution positions of different joints, and then compares them with the tire, and manually adjusts the joint position to disperse them. The operation is cumbersome and the production efficiency is low, which cannot meet the growing production needs of the automotive industry. Utility Model Content

The joint detection component 1 is fixedly arranged above the feed conveyor 3, and is used to detect the position information of the tire molding components on the feed conveyor 3, and transmit the detected information to the PLC control component; the tire molding components at least include an inner liner and a cord, and in this embodiment, the tire molding components include an inner liner, a first layer of cord and a second layer of cord. The bonding component 2 is close to the discharge port of the feed conveyor 3, and is used to adjust the rotation angle and make the tire molding components bonded. The PLC control component is used to convert the position information provided by the joint detection component 1 into a joint spacing and compare it with the set allowable value, and automatically adjust the rotation angle of the bonding component 2 according to the comparison result.

[0024] Furthermore, the joint detection component 1 includes a detection bracket 11 and a photoelectric sensor component fixedly arranged on the detection bracket 11, and the photoelectric sensor component is connected to the PLC control component; the detection bracket 11 is rotatably connected to a movable baffle 12 that forms a shielding match with the photoelectric sensor component, and the bottom end of the movable baffle 12 is provided with a detection wheel 13 that can drive the movable baffle 12 to rotate, and the detection wheel 13 abuts against the tire molding component. When in use, the tire molding component is transmitted to the joint detection component 1 along the feeding conveyor belt 3, and the detection wheel 13 is lifted after abutting against the tire molding component, driving the movable baffle 12 to rotate and lift, and the movable baffle 12 forms a shielding match with the photoelectric sensor component. The photoelectric sensor component transmits information to the PLC control component and records the position information of the joint.

[0025] Specifically, the photoelectric sensor component includes a first photoelectric sensor 14 and a second photoelectric sensor 15 arranged side by side, and the movable baffle 12 forms a shielding cooperation with the first photoelectric sensor 14 and the second photoelectric sensor 15 respectively during the rotation process.

[0026] When the detection wheel 13 is in the initial position, the movable baffle 12 is located below the first photoelectric sensor 14, and at this time the movable baffle 12 does not form a shielding cooperation with the photoelectric sensor component; when the detection wheel 13 abuts against the material head of the tire molding component, the material head of the tire molding component includes the inner lining material head, the first layer of cord material head and the second layer of cord material head. At this time, the detection wheel 13 is lifted, the movable baffle 12 is rotated and lifted, and the movable baffle 12 forms a shielding cooperation with the first photoelectric sensor 14; when the detection wheel 13 abuts against the semi-finished joint of the tire molding component, the semi-finished joint of the tire molding component includes the first layer of cord semi-finished joint 7 and the second layer of cord semi-finished joint 9. The semi-finished joint refers to the joint at the splicing point after the cord produced by the semi-finished process is cut and spliced.

According to the comparison result, the PLC control component automatically adjusts the fixed point angle of the bonding component 2 by a positive adjustment range of 1°. Specifically, the inner liner molding joint 5 is the joint after the inner liner material head is bonded on the bonding component 2, and the cord molding joint is the joint after the cord material head is bonded on the bonding component 2.

[0029] When in use, the joint detection component 1 detects the position information of the lining material head, the cord material head, and the cord semi-finished product joint and transmits it to the PLC control component. The PLC control component sets the position of the lining material head, i.e., the lining molding joint 5, on the bonding component 2 to the starting 0°. The PLC control component compares the joint spacing between the first layer of cord material head, i.e., the first layer of cord molding joint 6 and the lining molding joint 5 with the set allowable value. If it is less than the set allowable value, the PLC control component automatically adjusts the fixed point angle of the bonding component 2. Every adjustment of 1° is compared with the set allowable value, and the cycle is repeated until the joint spacing is greater than or equal to the set allowable value. The PLC control component automatically controls the bonding component 2 to rotate to the specified fixed point angle according to the adjusted fixed point angle value, and completes the bonding of the tire molding components and the dispersion and avoidance of each joint. The set allowable value is set according to the size of the molded tire, the spacing between the cord molding joint and the semi-finished product joint, and the production process requirements. The working principle of joint avoidance for the second layer of cord is the same as that for the first layer of cord. In addition to the inner lining forming joint 5, the positions of the first layer of cord forming joint 6 and the first layer of cord semi-finished product joint 7 must also be considered to ensure that all joints on the inner lining and different cords are evenly dispersed and avoided to avoid being too close or overlapping.

[0030] Specifically, the bonding component 2 includes a molding drum, which is arranged near the discharge port of the feeding conveyor belt 3. The rotating shaft of the molding drum is connected to the PLC control component. The PLC control component controls the molding drum to rotate to a specified fixed point angle according to the adjusted numerical value to ensure that the joint spacing of each joint of the tire molding component is greater than or equal to the set allowable value, thereby improving the accuracy of joint dispersion and avoidance.

[0031] Furthermore, a bonding conveyor belt 4 is provided between the discharge port of the feeding conveyor belt 3 and the forming drum, for providing a space for bonding preparation of the tire forming components.

[0034] The working process of the utility model is as follows: when in use, the tire molding component is transmitted to the joint detection component 1 along the feeding conveyor belt 3, and when the detection wheel 13 abuts against the material head of the tire molding component, the detection wheel 13 is lifted, and the movable baffle 12 is rotated and lifted to form a shielding cooperation with the first photoelectric sensor 14, and the first photoelectric sensor 14 transmits the position information of the molding joint of the tire molding component to the PLC control component; when the detection wheel 13 abuts against the semi-finished joint of the tire molding component, the detection wheel 13 is lifted, and the movable baffle 12 is rotated and lifted to form a shielding cooperation with the second photoelectric sensor 15, and the second photoelectric sensor 15 transmits the position information of the semi-finished joint of the tire molding component to the PLC control component. The PLC control component sets the position of the lining forming joint 5 on the bonding component 2 as the starting 0°, and compares the joint spacing between the first layer of curtain forming joint 6 and the lining forming joint 5 with the set allowable value. If it is less than the set allowable value, the PLC control component automatically adjusts the fixed-point angle of the bonding component 2 by comparing it with the set allowable value every time it is adjusted by 1°, and repeats the cycle until the joint spacing is greater than or equal to the set allowable value; the PLC control component automatically controls the bonding component 2 to rotate to the specified fixed-point angle according to the adjusted fixed-point angle value of the first layer of curtain, thereby completing the bonding of the first layer of curtain and the dispersed avoidance of each joint.

[0035] The position detection of the second layer curtain forming joint 8 and the second layer curtain semi-finished product joint 9 is the same as that of the first layer curtain, and will not be repeated here. The PLC control component compares the joint spacing between the second layer curtain forming joint 8 and the inner lining forming joint 5, the joint spacing between the second layer curtain forming joint 8 and the first layer curtain forming joint 6, and the joint spacing between the second layer curtain forming joint 8 and the first layer curtain semi-finished product joint 7 with the set allowable values ​​respectively. If it is less than the set allowable value, the PLC control component automatically adjusts the fixed point angle of the bonding component 2, and compares it with the set allowable value once every adjustment of 1°, and repeats the cycle until the joint spacing is greater than or equal to the set allowable value; the PLC control component automatically controls the bonding component 2 to rotate to the specified fixed point angle according to the adjusted fixed point angle value of the second layer curtain, completing the bonding of the second layer curtain and the dispersed avoidance of each joint.
