[0028] The tire tread fitting device further comprises a controller connected with the conveying belt assembly 10 and the deviation correction assembly, wherein the deviation correction assembly comprises a driving mechanism drivingly connected with the belt drum assembly 20, and the controller controls the movement of the belt drum assembly 20 through the driving mechanism.

[0029] The tire tread fitting device of the present application makes the whole detection and deviation correction process more automatic and intelligent by setting the controller, the driving mechanism in the deviation correction assembly adopts a servo motor, the servo motor drives the belt drum assembly 20 to slide along the second guide rail 36, so as to adjust the fitting position of the tire tread and the belt drum assembly 20 in the direction perpendicular to the conveying direction of the tire tread.

[0030] The tire tread fitting device further comprises a cutting assembly 60 arranged on the conveying belt assembly 10 to cut the tire tread.

[0031] The detection assembly 80 detects the position movement track of the tread after being cut by the cutting assembly 60, which is used to cut the tread into a predetermined length so that the tread is just wrapped around the belt drum.

[0032] The specific cutting method can adopt the following two methods:

[0033] The first cutting control method is that the tread fitting device further comprises a conveyor belt driving mechanism and a control switch 90, the conveyor belt driving mechanism is drivingly connected with the conveyor belt assembly 10 to drive the conveyor belt assembly 10 to move, and the control switch 90 is arranged on the conveyor belt assembly 10 to control the driving mechanism to start and stop by controlling the conveyor belt driving mechanism to cut the tread of a predetermined length by the cutting assembly 60.

[0034] The cutting principle is that the conveying speed of the conveyor belt assembly 10 is constant, the control switch 90 controls the driving mechanism to start and stop according to the distance traveled by the encoder, so that the conveyor belt assembly 10 always transports the tread according to the distance traveled by the encoder, and then the cutting assembly 60 cuts the tread when the conveyor belt assembly 10 stops, and the length of each tread is controlled by controlling the moving time and speed of the conveyor belt assembly 10.

[0035] The second cutting control method is that the tread fitting device further comprises a controller, which is connected with the detection assembly 80 and the cutting assembly 60 respectively, wherein the detection assembly 80 comprises a detection camera, which is arranged on the conveyor belt assembly 10 near the cutting assembly 60 on the side close to the belt drum assembly 20 to detect the moving position and length of the tread after passing through the cutting assembly 60.

[0036] The cutting principle is that the detection camera detects the moving position track of the tread on the conveyor belt assembly 10 in real time and transmits it to the controller, the controller matches the moving position track of the center of the tread with the center position of the belt drum assembly 20, and at the same time, the conveying speed of the conveyor belt assembly 10 and the rotating speed of the belt drum assembly 20 are taken into account, then the controller controls the belt drum assembly 20 to move to make the center of the tread of the belt drum assembly 20 fit, and at the same time, the length of the detected rubber material is compared with the circumference of the belt drum, and the rotating speed of the belt drum is adjusted by controlling the driving mechanism, or the conveying speed of the conveyor belt assembly 10 is adjusted by controlling the conveyor belt driving mechanism.

[0037] The method comprises the following steps: S1, unfolding and conveying the tire tread onto a conveying belt assembly 10; S2, detecting the moving position and / or moving speed and / or moving length of the tire tread on the conveying belt assembly 10 by a detection assembly 80; S3, calculating the offset between the moving position detected by the detection assembly 80 and the preset winding position on a belt drum assembly 20; and S4, controlling the belt drum assembly 20 to move to offset the offset, so that the tread is wound on the belt drum assembly 20 according to the preset winding position after correction.

[0038] The present application also provides a method for correcting the position of a tire tread, which is mainly used for correcting the position of the tire tread so that the tire tread can be attached to a belt drum assembly 20 according to a preset position. The method comprises the following steps: firstly, unfolding and conveying the tire tread onto a conveying belt assembly 10; secondly, moving the tire tread by the conveying belt assembly 10; thirdly, collecting the moving track and moving speed of the tire tread by a detection assembly 80; fourthly, transmitting the collected information to a controller; fifthly, calculating the moving length of the conveying belt assembly 10 and the offset between the center of the belt drum assembly 20 and the center of the tire tread by the controller according to the information collected by the detection assembly 80; and sixthly, controlling the conveying belt assembly 10 to start and stop so that a cutting assembly 60 cuts the tire tread, and controlling the belt drum assembly 20 to move to ensure that the center of the belt drum assembly 20 and the center of the tire tread completely match before the tire tread is attached.

[0039] In step S2, the detection assembly 80 detects the moving track of the center of the tire tread; and in step S3, the offset between the moving track of the center of the tire tread detected by the detection assembly 80 and the center of the belt drum assembly 20 is calculated.

[0040] In the method of the present application, the detection assembly 80 detects the moving position of the center of the tire tread, and the controller calculates the distance between the center of the tire tread and the center of the belt drum assembly 20.

[0041] The method for correcting the position of the tire tread further comprises a step S31 after step S2, in which the moving length of the tire tread detected by the detection assembly 80 is compared with the circumference of the belt drum on the belt drum assembly 20 to obtain an error value, and the rotating speed of the belt drum or the moving speed of the conveying belt on the conveying belt assembly 10 is adjusted according to the error value. In this way, a closed-loop automatic detection control is formed, and the rotating speed of the belt drum or the moving speed of the conveying belt is controlled in real time, so that the length of the cut rubber matches the circumference of the belt drum, and the center of the rubber matches the center of the belt drum, thereby solving the problem of poor tire quality.

[0042] The tire tread deviation correction method further comprises a step S32 after the step S2, the step S32: controlling the rotating speed of the belt drum according to the moving length and the moving speed of the tire tread detected by the detection assembly 80 and the circumference of the belt drum on the belt drum assembly 20, so that the tire tread is uniformly attached to the belt drum.

[0043] In the embodiment, the moving speed of the tire tread detected by the detection assembly 80 is matched with the rotating speed of the belt drum, so that the tire tread is uniformly attached to the belt drum, and the problems of the tire tread being stretched or wrinkled caused by the mismatch between the moving speed of the tire tread and the rotating speed of the belt drum are prevented.

[0044] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects:

[0045] The tire tread automatic deviation correction method mainly comprises the following steps: after the tire tread is guided by the guiding device and passes through the storage pocket, the tire tread is preliminarily centered by the mechanical distance adjusting assembly 50, and then the tire tread reaches the deviation correction sensor of the deviation correction assembly, the detection assembly 80 starts to record the process data of the tire tread, mainly the deviation data of the tire tread about the center line and the overall length measurement data, then reaches the control switch 90 position, after the control switch 90 is triggered, the control system starts to count and fix the length, when the tire tread reaches the set process length, the conveying belt assembly 10 temporarily stops conveying, and the tire tread cutting assembly 60 cuts the tire tread. At this time, the tire tread continues to be conveyed to the belt drum direction, the deviation correction system continues to record the data of the tire tread that has not passed through the detection range, when the tire tread completely passes through the detection range of the deviation correction sensor, the deviation data of the center of the tire tread and the length data of the overall tire tread are transmitted to the deviation correction controller processor. The control system continues to convey according to the recorded current position of the tire tread, and after being conveyed to the tire tread attachment position, the belt drum machine box and the drum are moved to the position where the center of the belt drum coincides with the center of the tire tread, and then the control system controls the belt drum machine box according to the data transmitted by the deviation correction system, so that the belt drum machine box moves left and right according to the data stored by the tire tread deviation correction system, to ensure that the center of the tire tread can be correctly attached to the center of the belt drum; meanwhile, according to the deviation between the length data of the tire tread recorded by the deviation correction system and the circumference of the belt drum, the rotating speed of the belt drum and the speed of the front conveying template of the tire tread are matched in speed, so that the tire tread is uniformly distributed on the circumference of the belt drum.

[0046] In specific use, the main process steps are as follows:

[0047] The tire tread guiding assembly 70 guides the tire tread from the I-beam material roll, and after the tire tread is centered by the tire distance adjusting assembly 50, the tire tread passes through the tire cutting assembly 60 and reaches the sensor sensing range of the tire detection assembly 80.

[0048] The tread detection assembly 80 starts to record the tread related process data, mainly including the offset data of the tread center line and the overall length data.

[0049] When the tread reaches the position of the tread control switch 90, the control switch 90 is triggered, and the PLC control system of the feeding frame starts to count the length of the tread. The conveying belt assembly 10 is divided into a front end feeding template of the tread and a rear end feeding template of the tread. The front end feeding template of the tread is located on the side close to the belt drum assembly 20. When the tread reaches the set process length, the front end feeding template of the tread temporarily stops conveying.

[0050] At this time, the tread cutting assembly 60 moves transversely to cut the tread.

[0051] The cut tread continues to be conveyed in the direction of the belt drum box and the belt drum under the control of the overall control system.

[0052] The tread passes through the tread detection assembly 80 at the same time, and the correction system continues to record the data of the tread that has not passed through. When the tread completely passes through the detection range of the correction sensor, the offset data of the center of the tread and the length data of the overall tread have been transmitted to the correction controller processor. Finally, the tread is conveyed to the front end of the template for bonding. The correction controller transmits the offset data of the center of the tread and the length data to the PLC processor.

[0053] The belt drum box and the drum along the box second guide rail 36 move to the position where the center of the belt drum coincides with the center of the tread.

[0054] At this time, the tread starts to be bonded by the compression roller assembly of the tread bonding device. The control system controls the belt drum box according to the data transmitted by the correction system, so that the belt drum box and the drum move left and right according to the data stored by the tread correction system, to ensure that the center of the tread can be correctly bonded on the center of the belt drum.

[0055] During the bonding process, according to the deviation between the length data of the tread recorded by the correction system and the circumference of the belt drum, the speed of the belt drum rotation and the speed of the front end conveying template of the tread are matched, so that the tread is evenly distributed on the circumference of the belt drum, and finally the tread bonding and joint are completed.
