[0024] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] In order to solve the problem of poor correction effect of steel cord rubber head and tail in the prior art, the present application provides a tire rubber correction method.

[0026] As shown in Fig. 1, a tire rubber correction method adopts the tire rubber correction device shown in Fig. 2, which includes a conveying device 10 and a first correction plate 20 arranged at an angle with the rubber conveying direction, and the tire rubber correction method includes: conveying the rubber to the first correction plate 20 by the conveying device 10, forming a predetermined distance between the end of the rubber and the first correction plate 20; driving the end of the rubber to move towards the first correction plate 20 by the conveying device 10, the bevel of the end of the rubber abuts against the stop of the first correction plate 20, and the end of the rubber is corrected in position under the stop action of the first correction plate 20.

[0027] In this embodiment, the end of the rubber is corrected by the first correction plate 20, so that the head 31 and / or the tail 32 of the rubber can be automatically corrected. Specifically, the first correction plate 20 is located on the conveying path of the rubber, and as the conveying device 10 conveys, the rubber is conveyed to a predetermined position, at which time the correction process is performed. The conveying device 10 drives the rubber to be conveyed towards the first correction plate 20 until the head 31 or the tail 32 of the rubber abuts against the side edge of the first correction plate 20. At this time, the head 31 or the tail 32 moves under the stop action of the first correction plate 20, so that the position of the head 31 or the tail 32 is aligned with the first correction plate 20, thereby realizing the correction of the head 31 and / or the tail 32, so that the rubber can be more accurate and reliable in subsequent butt joint and other processing. The above setting mode can realize the automatic correction of the end of the rubber, and the accuracy and reliability of the correction are greatly improved, and the correction efficiency is also greatly improved, which helps to improve the production efficiency.

[0028] The tire rubber material correction method of the embodiment is mainly used for correcting rubber materials with reinforcing structures, that is, steel wire skeleton rubber materials, and more specifically, belt or full steel body ply. The embodiment is described by taking the rubber material as a steel wire rubber material, the steel wire is arranged in the rubber material, so that the rubber material can abut against the first correction plate 20 for correction and will not return to the state before correction after correction, and the rubber material is corrected and then subjected to a bonding operation. Of course, the tire rubber material correction method of the embodiment is also applicable to other types of rubber materials, and other processing operations can also be performed after the rubber material correction is completed.

[0029] It should be noted that the end of the rubber material in the embodiment includes two ends of the head 31 and the tail 32, and in actual use, only one of the head 31 and the tail 32 can be corrected as needed, or the head 31 and the tail 32 can be corrected respectively. The embodiment adopts the mode of correcting the head 31 and the tail 32 respectively, so that the position accuracy of the head 31 and the tail 32 can be ensured during subsequent bonding and docking, thereby ensuring the accuracy and reliability of the docking.

[0030] Optionally, the tire rubber material correction method further comprises: the conveying device 10 conveying the rubber material to the first correction plate 20 at least once. When the conveying device 10 conveys the rubber material to the first correction plate 20 only once, it is only the head 31 or the tail 32 that is corrected. When the conveying device 10 conveys the rubber material to the first correction plate 20 multiple times, the head 31 and the tail 32 can be corrected respectively.

[0031] Specifically, as shown in FIG. 3, when the head 31 is corrected, the conveying device 10 conveys the rubber material to the first correction plate 20, at this time, the rubber material is located on the upstream side of the first correction plate 20, that is, the rubber material and the first correction plate 20 are sequentially arranged in the conveying direction, at this time, the conveying device 10 can continue to convey the rubber material, the end of the rubber material is in abutting and cooperating with the stop of the first correction plate 20, at this time, the bevel of the head 31 of the rubber material abuts and cooperates with one side of the stop of the first correction plate 20, thereby achieving the effect of correcting the head 31. As shown in FIG. 4, when the tail 32 is corrected, the conveying device 10 conveys the rubber material to the first correction plate 20, at this time, the rubber material is located on the downstream side of the first correction plate 20, that is, the first correction plate 20 and the rubber material are sequentially arranged in the conveying direction, at this time, the conveying device 10 reversely conveys the rubber material, the end of the rubber material is in abutting and cooperating with the stop of the first correction plate 20, at this time, the bevel of the tail 32 of the rubber material abuts and cooperates with the other side of the stop of the first correction plate 20, thereby achieving the effect of correcting the tail 32. Through the above-mentioned mode, the effect of respectively correcting the head 31 and the tail 32 can be achieved through the two sides of the first correction plate 20. When only one of the head 31 and the tail 32 is corrected, only one of the above-mentioned modes can be implemented.

[0032] It should be noted that the above two processes of correcting the head 31 and the tail 32 do not have an order requirement, and the tail 32 can be corrected first, and then the head 31 is corrected, but the embodiment preferably corrects the head 31 first, and then corrects the tail 32, so as to improve the correction efficiency and avoid unnecessary time waste caused by multiple reciprocating movements of the conveying device 10.

[0033] In the embodiment, the tire rubber material correction device further comprises a cutting device, and the tire rubber material correction method further comprises: the conveying device 10 conveying the rubber material to the first correction plate 20 at least twice, and the head 31 and the tail 32 of the rubber material abut against the two sides of the first correction plate 20, so as to sequentially correct the head 31 and the tail 32. Based on different processing modes of the rubber material, the rubber material can be in a state of having been cut during the correction of the head 31, or can be in a state of not being cut, that is, the tail 32 can be processed and completed during the correction of the head 31, or can be not processed. Therefore, the tire rubber material correction method further comprises: the cutting device cuts the rubber material before or after the correction of the head 31 is completed. If the cutting is performed before the correction of the head 31 is completed, the rubber material is a completed segment at this time, and it can not be cut again. After the correction of the head 31 is completed, the conveying device 10 continues to convey the rubber material, so that the rubber material passes over the first correction plate 20, and the tail 32 is corrected. If the cutting is not performed during the correction of the head 31, the cutting device can cut the rubber material after the correction of the head 31 is completed. At this time, the rubber material can be temporarily stopped for a short time according to needs, and after the tail 32 is cut, the conveying device 10 continues to convey the rubber material to correct the tail 32.

[0034] In the embodiment, the tire rubber material correction device further comprises a position detection device, and the position detection device is used to detect the position of the rubber material to determine the state of the rubber material. The tire rubber material correction method further comprises: when the conveying device 10 conveys the rubber material to the first correction plate 20, the position detection device detects the position of the end of the rubber material that needs to be corrected, that is, the position of the head 31 or the tail 32, so as to obtain the position of the head 31 or the tail 32, and then determine whether the rubber material is conveyed to the position. When the distance between the end of the rubber material and the first correction plate 20 is a predetermined distance, that is, when the rubber material is conveyed to a position corresponding to the predetermined distance, the rubber material is conveyed to the position. At this time, the conveying device 10 can be controlled to adjust the conveying state, so that the conveying device 10 is switched from the normal conveying state to the correction conveying state.

[0035] Optionally, the normal conveying state and the correcting conveying state can be the same or different as required, that is, the state of the conveying device 10 can be the same or different before and during the correction of the tire rubber. Specifically, the tire rubber correcting method further comprises: before the distance between the end of the rubber and the first correcting plate 20 reaches a predetermined distance, that is, before the rubber is conveyed to a predetermined position, the conveying device 10 conveys the rubber at a first speed; after the distance between the end of the rubber and the first correcting plate 20 reaches the predetermined distance, that is, when the rubber is conveyed from the predetermined position to the first correcting plate 20 for correction, the conveying device 10 conveys the rubber at a second speed; wherein the first speed is greater than or equal to the second speed. The embodiment adopts the setting mode that the first speed is greater than the second speed, so that the conveying device 10 first conveys the rubber to the predetermined position at a faster speed, and then conveys the rubber to approach the first correcting plate 20 at a lower speed until the rubber abuts against the first correcting plate 20, thereby ensuring the accuracy of the stop correcting and avoiding the situation of excessive correction caused by excessive speed.

[0036] Optionally, the position detection device has various setting modes, which can separately set position detection sensors and other components on the conveying device 10 to realize the position detection of the rubber, or can adopt other devices such as the cutting device as the position detection device, for example, taking the position of the cutting device cutting the rubber as the initial position of the rubber, and calculating the distance difference between the initial position and the predetermined position during correction, so that the conveying device 10 can convey the rubber according to the distance difference by using a servo conveying mode, so that the rubber can be accurately conveyed at the predetermined position during correction, and for another example, taking the deviation correcting device as the position detection device, and taking the position of the deviation correcting device as the initial position of the rubber, and calculating the conveying distance of the rubber according to the initial position and the predetermined position, and then performing fixed-length conveying.

[0037] The position detection device of the embodiment comprises a measurement sensor, and the tire rubber correcting method further comprises: when the conveying device 10 conveys the end of the rubber to the position of the measurement sensor, the end of the rubber triggers the measurement sensor, and the measurement sensor generates trigger information and measures the length of the rubber according to the trigger information. Specifically, the measurement sensor can detect the head 31 and the tail 32 of the rubber respectively, triggers the measurement sensor when the head 31 passes through the measurement sensor, and triggers the measurement sensor again when the tail 32 passes through the measurement sensor, and the measurement sensor can generate position, time and other trigger information during the two triggering processes, so that the length of the rubber can be calculated according to the trigger information to realize the measurement of the length of the rubber.

[0038] In the embodiment, the measuring sensor comprises a first detection member and a second detection member, wherein the first detection member and the second detection member are respectively located at two sides of the first correction plate 20, so that the positions of the head 31 and the tail 32 can be detected respectively. Of course, when only one of the head 31 and the tail 32 is corrected, only one detection member can be arranged for corresponding detection. Correspondingly, the tire rubber correction method further comprises: when the distance between the head 31 of the rubber and the first correction plate 20 reaches a predetermined distance, the head 31 triggers the first detection member, the first detection member judges that the head 31 is transported to the position, and the subsequent correction process of the head 31 is performed; when the distance between the tail 32 of the rubber and the first correction plate 20 reaches a predetermined distance, the tail 32 triggers the second detection member, the second detection member judges that the tail 32 is transported to the position, and the subsequent correction process of the tail 32 is performed.

[0039] The first detection member and the second detection member of the embodiment have other functions in addition to the function of position detection cooperating with the correction process. Specifically, the first detection member of the embodiment is a fixed-length switch, which is located on the upstream side of the first correction plate 20. When the head 31 of the rubber is transported to the position of the fixed-length switch by the conveying device 10, the fixed-length switch detects the position of the head 31 and fixes the length of the rubber on the other hand, thereby realizing the detection of the initial position of the head 31 correction and the length fixing of the rubber. Similarly, the second detection member of the embodiment is a length measuring switch, which is located on the downstream side of the first correction plate 20. When the tail 32 of the rubber is transported to the position of the length measuring switch by the conveying device 10, the length measuring switch detects the position of the tail 32 and measures the length of the rubber on the other hand, thereby realizing the detection of the initial position of the tail 32 correction and the length measuring of the rubber. The cooperation of the above-mentioned length measuring switch and the fixed-length switch realizes the accurate and reliable length of the rubber.

[0040] In the embodiment, in addition to the first correction plate 20 for stopping and correcting the bevel of the end portion, the tire rubber correction device further comprises a second correction plate 40 arranged in the conveying direction, and the second correction plate 40 is located at the first side edge of the rubber, so that the first correction plate 20 and the second correction plate 40 can stop the bevel and the side edge of the rubber respectively, thereby improving the accuracy of correction. Correspondingly, the tire rubber correction method further comprises: when the bevel of the end portion of the rubber is stopped and abuts against the first correction plate 20, the first side edge of the end portion of the rubber abuts against the second correction plate 40, and the end portion of the rubber is corrected in position under the combined stopping action of the first correction plate 20 and the second correction plate 40. It should be noted that the correction mode of the two correction plates together is applicable to the correction of the head 31 and the tail 32.

[0041] The two second correction plates 40 are arranged on the same side of the rubber material, so that the two second correction plates 40 form a H-shaped structure.

[0042] The Z-shaped structure is used to stop and abut the bevel and the side edge that forms an acute angle with the bevel, so that the correction effect is better. Of course, in addition to the side edge that forms an acute angle with the bevel, the side edge that forms an obtuse angle with the bevel can also be used for stopping and correction.

[0043] Optionally, in addition to the second correction plate 40, the tire rubber material correction device can also include a third correction plate arranged in the conveying direction, and the third correction plate is arranged at the second side edge of the rubber material, so that the second correction plate 40 and the third correction plate are arranged on the two sides of the rubber material, so that when stopping and correcting, the three correction plates can surround the three edges of the end of the rubber material, and the correction is realized by stopping the three edges. Correspondingly, the tire rubber material correction method also includes: when the bevel of the end of the rubber material is stopped and abutted by the first correction plate 20, the first side edge of the end of the rubber material is abutted by the second correction plate 40, and the second side edge of the end of the rubber material is abutted by the third correction plate, the second side edge and the first side edge are arranged on the opposite sides of the rubber material, and the end of the rubber material is corrected in position under the combined stopping action of the first correction plate 20, the second correction plate 40 and the third correction plate. It should be noted that the above-mentioned three-edge stopping and correction method can be used for the correction of the material head 31 and the material tail 32, and when the material head 31 and the material tail 32 are used at the same time, the three correction plates form a H-shaped structure, and the middle section of the H-shaped structure is inclined compared with the two side sections.

[0044] It should be noted that the first side edge and the second side edge of the rubber material mentioned in the embodiment are the side edges in the length direction of the rubber material, that is, the side edges that are substantially parallel to the conveying direction.

[0045] In the embodiment, the angle of the first correction plate 20 relative to the conveying direction is adjustable, and the adjustment manner can be set as required, for example, through a servo motor cooperating with a gear assembly and being drivingly connected with the first correction plate 20, and then the servo motor drives the first correction plate 20 to rotate transversely to adjust the angle. Alternatively, the first correction plate 20 can be manually adjusted or adjusted in other manners. Correspondingly, the tire rubber correction method further comprises: before the bevel edge of the rubber end portion abuts against the first correction plate 20, adjusting the inclination angle of the first correction plate 20 relative to the conveying direction, and forming a predetermined angle between the first correction plate 20 and the conveying direction. The predetermined angle is the angle required by the bevel edge of the rubber, so that the position of the bevel edge after the correction can meet different requirements and improve the adaptability to the rubber. The timing of adjusting the angle of the first correction plate 20 can be before the correction, for example, when the rubber is conveyed to the predetermined position and is about to be corrected, or before the rubber is conveyed, as long as the angle of the first correction plate 20 meets the requirements during the correction.

[0046] In addition to the angle of the first correction plate 20 being adjustable, when the second correction plate 40 and the third correction plate and other correction plates are provided, the relative positional relationship among the first correction plate 20, the second correction plate 40 and the third correction plate can also be adjusted, for example, the distance relationship between the first correction plate 20 and the second correction plate 40 is adjusted, so that different specifications of rubber can be adapted.

[0047] As shown in FIG. 2, in the embodiment, the first correction plate 20 is provided to be liftable, and the lifting of the first correction plate 20 is mainly to enable the rubber to pass over the first correction plate 20 during the conveying of the rubber, so as to realize the smooth conveying of the rubber. The tire rubber correction method further comprises: when the conveying device 10 conveys the rubber head 31 to the position directly below the first correction plate 20, the first correction plate 20 is lifted, and when the rubber tail 32 completely passes through the first correction plate 20, the first correction plate 20 is lowered to the conveying device 10. It should be noted that as long as the position of the rubber conveying needs to pass through the first correction plate 20, whether the correction of the rubber head 31 is completed or the correction of the rubber head 31 is not required, the first correction plate 20 needs to be lifted, so that the first correction plate 20 avoids the conveying path of the rubber, and the rubber can be conveyed smoothly. The lifting of the first correction plate 20 can be provided with a lifting assembly 50, and the lifting assembly 50 can comprise a support and a lifting motor, the support is connected with the conveying device 10, and a lifting driving member is drivingly connected between the first correction plate 20 and the like, so as to drive the first correction plate 20 to lift and move.

[0048] Optionally, the first correction plate 20, the second correction plate 40 and the third correction plate can be arranged in a split manner, that is, the three are single independent components, and the lifting of the first correction plate 20 does not affect the second correction plate 40 and the third correction plate. At this time, the second correction plate 40 and the third correction plate can be kept stationary or can be lifted. The first correction plate 20, the second correction plate 40 and the third correction plate can also be arranged in an integrated manner, so that the three form an integral component. In this way, the lifting of the three is in a synchronous form.

[0049] The overall use process of the tire rubber material correction method of the embodiment is as follows. Take the example that the correction plate is provided with the first correction plate 20 and two second correction plates 40 and forms a Z-shaped structure, and the head 31 and the tail 32 are respectively corrected.

[0050] The conveying device 10 conveys the cut rubber material to the first correction plate 20. When the head 31 of the rubber material is conveyed to the predetermined position, the head 31 triggers the measurement sensor, and the measurement sensor detects the head 31 to determine the position of the head 31 and perform length measurement. Then the conveying device 10 continues to convey the rubber material. At this time, the first correction plate 20 is in a lowered position, and the bevel and one side edge of the head 31 are respectively stopped by the first correction plate 20 and the second correction plate 40 to correct the head 31. After the head 31 is corrected, the first correction plate 20 rises to avoid the conveying of the rubber material. The conveying device 10 continues to convey the rubber material until the length measurement switch triggers once to detect the position of the head 31, and then the length measurement is started. Subsequently, the tail 32 reaches the position of the length measurement switch, and the length measurement switch triggers twice to detect the position of the tail 32. The length measurement switch performs length measurement operation, and the conveying device 10 stops conveying at the same time. The first correction plate 20 is lowered to the conveying device 10, and the conveying device 10 reversely conveys the rubber material so that the tail 32 gradually approaches the first correction plate 20. The bevel and one side edge of the tail 32 are respectively stopped by the first correction plate 20 and the second correction plate 40 to correct the tail 32. After the head 31 and the tail 32 are corrected, the conveying device 10 conveys the rubber material to the subsequent laminating equipment for corresponding processing operation.
