Description

Technical Field

[0001] The invention relates to the field of tire production equipment, in particular to an online sidewall puncturing device capable of simultaneously puncturing two sidewalls placed at a certain distance, and a tire body feeding rack and a tire forming machine containing the same. Background Art

[0002] Attached Figure 1 This is a half-section view of a raw tire. During the molding process of an existing raw tire, after the carcass assembly is attached to the molding drum, two tire beads 104 need to be placed at designated positions outside the carcass assembly, and then the first sidewall and the second sidewall located at the two ends of the carcass assembly in the carcass assembly are reversely coated on the middle area of ​​the carcass assembly. Since the tire bead 104 and the sidewall 105 cannot be completely attached to each other at the position close to the tire bead 104 during the reverse coating process, bubbles will be generated. These bubbles may cause the tire to delaminate, and may even cause a blowout during the vulcanization process, thereby affecting the production quality of the tire and the qualified product rate during the production process, so it is necessary to eliminate these bubbles through the spike portion.

[0003] The existing equipment eliminates bubbles in the following two ways: 1. During the drum forming stage of the green tire, the first sidewall and the second sidewall are reversely wrapped on the carcass assembly to eliminate bubbles. In this process, there are the following deficiencies: 1) Eliminating bubbles during the drum forming stage will directly extend the operation time on the drum and reduce the forming production efficiency; 2) Since the sidewall and other inner liner layers have been bonded during the drum forming stage, it is easy to pierce the inner liner or other composite layers during the bubble elimination process through the spikes, thus affecting the tire quality.

[0004] Second, after the sidewall is punctured separately, the punctured sidewall is rolled up. In the subsequent production, the punctured sidewall needs to be unrolled and then attached to the forming drum. The sidewall needs to be repeatedly rolled up and unrolled. In this process, there are also the following shortcomings: 1) When the punctured sidewall is rolled up and then unrolled, the puncture on the sidewall may be blocked again, so that the punctured sidewall cannot be vented during the wrapping process and bubbles are still generated; 2) Repeated unrolling and winding of the material roll results in a lot of work waste.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0030] like Figures 3 to 10 As shown, the present invention discloses an online sidewall puncturing device 1, comprising a rotatable support mechanism 10, wherein the support mechanism 10 has a support roller 11 and a support component 12 arranged on the support roller 11, wherein the support mechanism 10 is used to support the sidewall; a driving mechanism 20, wherein the driving mechanism 20 is used to drive the support mechanism 10 to rotate so as to transport the sidewall; and further comprising two groups of puncturing mechanisms 30 arranged above the support mechanism 10 and opposite to the support component, wherein the two groups of puncturing mechanisms 30 are arranged at a certain interval (the interval is the same as the interval between the two tires). The puncturing mechanism 30 comprises a rotatable licker-in roller 31, and at least one group of puncture parts 311 is arranged on the circumference of the licker-in roller 31; the support part 12 comprises a support body 121, and the support body 121 has a plurality of support members 122 arranged at equal intervals, and an escape space 123 for accommodating the puncture parts is formed between any two adjacent support members 122 and the support body 121, and the support body 121 and the support member 122 can be arranged in one piece or separately. When in use, the sidewall is supported on a surface formed by a plurality of support members 122, and the needle component 311 in the puncturing mechanism 30 passes through the sidewall and is placed in an avoidance space 123 formed by the support member 122 and the support body 121 to avoid interference with the support member 122. When the driving mechanism 20 drives the supporting mechanism 10 to rotate, the sidewall is transported forward, thereby driving the licker-in roller 31 to rotate, so that a group of needle components 311 arranged on the circumference of the licker-in roller 31 are always puncturing the transported sidewall, and when the licker-in roller 31 rotates, the needle component 311 is always moving in the avoidance space 123.

[0031] Through the above arrangement, the two sets of sidewalls 101 arranged at a certain distance are punctured at the same time. After the sidewalls 101 are punctured, the inner liner 102 of the two sets of punctured sidewalls 101 can be directly attached to form a Figure 2 The sidewall inner liner 103 shown makes it easy to directly adhere the sidewall inner liner 103 to the molding drum for the molding production of the green tire, so there is no need to repeatedly roll up the sidewall material, guide the material roll, etc., which can improve production efficiency and reduce waste; the sidewall after puncture is directly used for molding production, there is no risk of the sidewall puncture being blocked, and the exhaust can be ensured during the reverse packaging process during the molding production, thereby eliminating bubbles.

[0032] like Figure 8 and 9 As shown, the licker-in roller 31 of the present invention may be provided with multiple rows of needle components 311 along the circumference of the licker-in roller, so as to realize multiple rows of puncture holes on the sidewall. Since the size and number of puncture holes will affect the exhaust effect during the forming and turning-up, preferably, when the diameter of the puncture components 311 is between 1 mm and 3 mm, and the working length of the puncture components 311 extending from the surface of the licker-in roller 31 is between 15 mm and 25 mm, the puncture holes on the sidewall have the best effect. In a row of puncture components 311 on the circumference of the licker-in roller, when the spacing H1 of the puncture components 311 between the front and rear is between 10 mm and 25 mm, and in multiple rows of puncture components 311 on the circumference of the licker-in roller, when the spacing H2 of the puncture components 311 between two rows is between 15 mm and 40 mm, it is least likely to generate bubbles when the sidewall is turned up, and the turning-up quality is the best. In any two rows of needle components 311, two consecutive needle components 311 are randomly selected from each row, and the figure formed is a parallelogram, and when the parallelogram formed by the four needle components 311 is a non-rectangular parallelogram, that is, the two rows of needle components 311 are staggered and not in the same column, the obtained punctured sidewall has the best exhaust effect when it is turned up, and it is least likely to generate bubbles. The needle component 311 of the present invention is arranged on the licker-in roller 31 through a threaded connection, and the working length extending from the surface of the licker-in roller 31 can be adjusted through the thread.

[0033] It should be noted that the thickness of the support members 122 and the intervals between the support members 122 are set corresponding to the arrangement of the puncture needle components 311, so that during the rotation of the puncture roller 31, the puncture needle components 311 will not come into contact and interfere with the support member 122 body, thereby puncturing the sidewall more smoothly.

[0034] like Figure 8As shown, the puncturing mechanism 30 of the present invention comprises a first support 32, on which a pin 33 is arranged, and the licker-in roller 31 is rotatably arranged on the pin 33. The puncturing member 311 on the licker-in roller 31 of the present invention needs to puncture the sidewall (the puncturing of the present invention refers to forming a through hole on the sidewall). After the sidewall is punctured, the driving mechanism 20 drives the support mechanism 10 to rotate and drive the sidewall to be transported, thereby driving the licker-in roller 31 to rotate so that the puncturing member 311 pierced into the sidewall is separated from the sidewall. When the width of the hole required to be punctured on the sidewall is large, if all the puncturing members 311 are only arranged on one licker-in roller 31, when the puncturing member 311 inserted into the sidewall is separated from the sidewall, the more puncturing members 311 on the licker-in roller 31 are pierced into the sidewall, the greater the resistance encountered when separating from the sidewall, that is, the puncturing member 311 inserted into the sidewall is less likely to be separated from the sidewall, and the sidewall may be pulled up, resulting in deformation or damage to the sidewall. Therefore, in order to solve the above technical problems, preferably, when the sidewall portion to be punctured is wider, multiple groups of rotatable licker-in rollers 31 are provided on the pin shaft 33, instead of multiple groups of licker-in parts 311 being provided on one licker-in roller 31, so that each licker-in roller 31 has less resistance when the licker-in parts 311 are separated from the sidewall, and the licker-in parts 311 can be separated from the sidewall more easily. Preferably, when multiple groups of licker-in rollers 31 are provided, and there are two groups of licker-in parts 311 on each licker-in roller 31, the puncturing effect is the best and the licker-in parts 311 are most easily separated from the sidewall.

[0035] like Figure 5 As shown, optionally, the sidewall puncturing device of the present invention further includes a conveying mechanism 40, the conveying mechanism 40 includes a rotatable conveying roller 41 and a conveying belt (not shown) arranged on the conveying roller 41, the conveying roller 41 is arranged in front of the support mechanism 10 along the conveying direction of the sidewall, the diameter of the conveying roller 41 is the same as the diameter of the support component 12, the conveying roller 41 is connected to the driving mechanism 20, and the driving mechanism 20 is used to drive the conveying roller 41 to rotate. When in use, the sidewall is placed on the support component 12 and the conveying belt. When the puncturing roller 31 punctures the sidewall, the conveying belt on the conveying roller 41 exerts a forward conveying force on the sidewall, so that the puncturing needle component 311 pierced into the sidewall is better separated from the sidewall. The diameter of the conveying roller 41 is equal to the diameter of the support component 12, so as to ensure that the rotation linear velocity on the conveying roller 41 is equal to the rotation linear velocity on the support component 12, and avoid the problem of stretching and stacking of the sidewall passing through the conveying belt and the support component 12.

[0036] like Figure 4 and 5As shown, the driving mechanism 20 of the present invention includes a first driving source 21 and a transmission mechanism 22 driven by the first driving source 21, and the transmission mechanism 22 is respectively connected to the support mechanism 10 and the conveying roller 41, and is used to simultaneously drive the support mechanism 10 and the conveying roller 41 to rotate. Specifically, the conveying roller 41 is connected to the first driving source 21, and the support component 12 is arranged on the support roller shaft 11 and can rotate following the support roller shaft 11. The support roller shaft 11 and the conveying roller 41 are connected through the transmission mechanism 22. When the first driving source 21 drives the conveying roller 41 to rotate, the support roller shaft 11 is driven to rotate through the transmission mechanism 22, thereby driving the support component 12 arranged on the support roller shaft 11 to rotate. Preferably, the transmission mechanism 22 can be a combination of a synchronous belt and a synchronous pulley.

[0037] like Figure 6 As shown, since the needle component 311 on the licker-in roller 31 is arranged on the circumference of the licker-in roller 31, the licker-in roller 31 will puncture the sidewall as long as it contacts the sidewall. Therefore, in order to realize the automatic operation of puncturing the sidewall, that is, the licker-in roller 31 will contact the sidewall only when the sidewall puncture is required, the puncturing mechanism 30 of the present invention also has a swing mechanism 50. Specifically, the swing mechanism 50 includes a driving support 51 and a first swing driving source 52, the driving support 51 is hingedly arranged with the first support 32, the first swing driving source 52 is arranged on the driving support 51, the driving end of the first swing driving source 52 is hingedly arranged with the first support 32, the first swing driving source 52 is used to drive the first support 32 to rotate around the driving support 51, thereby driving the licker-in roller 31 to approach the support component 12 or to move away from the support component 12, and when the licker-in roller 31 is close to the support component 12, the licker-in roller 31 is used to puncture the sidewall.

[0038] Due to different specifications of tires, the width of the sidewall inner liner 103 after the two sidewalls 101 and the inner liner 102 are attached is different, that is, the spacing between the two sidewalls is required to be different, and the spacing between the two sets of puncturing mechanisms 30 described in the present invention needs to be adjusted. Figure 4 and 5As shown, in order to adjust the spacing of the puncturing mechanism 30, the tire side puncturing device of the present invention is provided with a first width adjustment mechanism 60, which includes a first base plate 61, and the two groups of puncturing mechanisms 30 are movably arranged on the first base plate 61 through a first moving assembly 62 (such as a slider and a guide rail), and also includes a second driving source 63 arranged on the first base plate 61, and a first screw rod 65 with opposite thread rotation directions respectively connected to the two groups of puncturing mechanisms 30 through a first nut 64, and the driving end of the second driving source 63 is directly or through a transmission device connected to the first screw rod 65, which is used to drive the first screw rod 65 to rotate. When the second driving source 63 drives the first screw rod 65 to rotate, it drives the two groups of first nuts 64 on the first screw rod 65 to be relatively close or relatively far away, thereby driving the two groups of puncturing mechanisms 30 connected to the first nut 64 to be close or far away respectively to adjust the spacing. The second driving source 63 may be an adjustment handle to manually adjust the spacing of the piercing mechanisms 30 ; the second driving source 63 may also be a motor or a cylinder to automatically adjust the spacing of the piercing mechanisms 30 .

[0039] It should be noted that if Figure 7 As shown, after the spacing between the two sets of puncturing mechanisms 30 is adjusted, the needle components 311 on the licker-in roller 31 always need to be opposite to the avoidance space 123 on the support component 12, that is, when the licker-in roller 31 rotates to puncture the sidewall, the licker-in component 311 needs to move in the avoidance space 123 without colliding with the support member 122. In order to achieve better support of the sidewall by the support member 12, the distance between the support members 122 on the support member 12 will be smaller. In this case, the positions of the licker-in roller 31 and the support member 12 need to be accurately adjusted so that the licker-in roller 31 can fall into the avoidance space 123. When there are multiple licker-in rollers 31 on the puncturing mechanism 30, this debugging takes a lot of time.

[0040] Therefore, to simplify debugging, Figure 5 and 6 As shown, optionally, the support component 12 described in the present invention has two groups, and the two groups of support components 12 are movably arranged on the support roller 11 and are respectively arranged opposite to the two groups of puncturing mechanisms 30, and also include a synchronous adjustment mechanism 70 connecting the puncturing mechanism 30 and the support component 12. When the two groups of puncturing mechanisms 30 are adjusted, the two groups of support components 12 can be synchronously driven to move at equal distances, so that the needle component 311 on the puncturing mechanism 30 after adjustment always falls into the avoidance space 123 of the support component 12.

[0041] like Figure 6 and 8As shown, specifically, the synchronous adjustment mechanism 70 includes an adjustment member 71 disposed on the puncture mechanism 30, and a slot roller 72 connected to the support member 12, the slot roller 72 can be fixedly disposed with the support member 12 so as to rotate together, or can be rotatably disposed on the support member 12 through a bearing member (not shown), and rotate independently relative to the support member 12, the slot roller 72 is provided with a slot portion 721, and the adjustment member 71 is provided with an adjustment end 711, the adjustment end 711 can be placed in the slot portion 721 and cooperate with the slot portion 721 to drive the slot roller 72 to move synchronously, and the adjustment end 711 is in an arc shape. When in use, the adjustment end 711 of the adjustment member is disposed in the slot portion 721 of the slot roller 72, and when the puncture mechanism 30 is driven by the second driving source 63 to adjust the spacing, the adjustment member 71 is driven to move along the width direction of the tire sidewall, and further drives the slot roller 72 to move synchronously, thereby driving the support member 12 connected to the slot roller 72 to move. The above arrangement can realize synchronous movement of the supporting component 12 and the puncturing mechanism 30, which can simplify the production changeover and debugging of sidewalls of different specifications and greatly shorten the debugging time.

[0042] Of course, in order to realize the movable setting of the piercing mechanism 30 relative to the supporting component 12, thereby facilitating the position adjustment of the piercing mechanism 30 separately, the adjusting member 71 described in the present invention can be movably set on the piercing mechanism 30 through a slotted hole (not shown).

[0043] Since the thickness of the sidewall is different at different locations and is thinner at the edge, during the transportation of the sidewall, the sidewall cannot be directly fixed within a certain width by a certain blocking member for transportation, otherwise the sidewall edge will be flipped upward by the force of the blocking member, causing the sidewall to deform or break. However, since the two sets of sidewalls will directly fit with the inner liner 102 after being punctured, there are high requirements for the position of the sidewall during the puncture process, otherwise it will not be able to directly fit with the inner liner 102. Figure 3 and 5 As shown, in order to maintain the position requirement of the sidewall during transportation, the sidewall puncturing device described in the present invention also includes a real-time correction unit 80, and the real-time correction unit 80 includes a detection element 81 and a transportation adjustment mechanism 82. The detection element 81 has a detection reference line (not shown). The detection element 81 is used to detect the side position of the sidewall and compare it with the detection reference line in real time. The position of the sidewall is adjusted by the transportation adjustment mechanism 82 so that the side edge of the sidewall is aligned with the detection reference line, thereby realizing real-time correction of the sidewall.

[0044] like Fig.10As shown, the conveying adjustment mechanism 82 includes a support seat 821, an adjustment driving source 822 fixedly arranged on the support seat 821, and a conveying roller group 823 movably arranged on the support seat 821. The conveying adjustment mechanism 82 is adjacent to the support component 12, and the detection element 81 is arranged at the output end of the conveying adjustment mechanism 82, and is located above the conveying adjustment mechanism 82. When in use, the sidewall passes through the conveying roller group 823 and then reaches the support component 12. The detection element 81 is used to detect the side position of the sidewall and compare it with the detection reference line. The conveying roller group 823 is driven to move on the support seat 821 by the adjustment driving source 822, so as to adjust the position of the sidewall placed on the conveying roller group 823.

[0045] The coordinated adjustment process of the detection element 81 and the conveying adjustment mechanism 82 can be as follows: when the detection element 81 detects that the side edge of the tire is in the right area of ​​the detection reference line, it means that the side edge is in the right side position of the conveying roller group 823 and the supporting component 12, and the control system controls the adjustment drive source 822 to drive the conveying roller group 823 to move to the left, driving the side edge to move to the left to correct its position; when the detection element 81 detects that the side edge of the tire is in the left area of ​​the detection reference line, it means that the side edge is in the left side position of the conveying roller group 823 and the supporting component 12, and the control system controls the adjustment drive source 822 to drive the conveying roller group 823 to move to the right, driving the side edge to move to the right to correct its position. The control system controls the adjustment drive source 822 to drive the conveying roller group 823 to move, so that the side edge of the tire is aligned with the detection reference line, thereby correcting the side position of the tire in real time.

[0046] Since the moving stroke of the conveying roller group 823 during the tire side deviation correction process is certain, when the tire side exceeds the moving stroke of the conveying roller group 823, the correction operation cannot be continued. Therefore, the real-time correction unit 80 of the present invention also includes a pre-limited roller group 83 with adjustable spacing and a material picking mechanism 84, wherein the pre-limited roller group 83 is used to limit the tire side to move within a certain range; the material picking mechanism 84 is used to reset the tire side that exceeds the moving stroke of the conveying roller group 823, and includes a second swing driving source 841 and a material picking roller 842 driven by the second swing driving source 841 to swing. When the tire side moves beyond the moving stroke of the conveying roller group 823, the second swing driving source 841 drives the material picking roller 842 to swing upward, driving the tire side to be lifted and then lowered. Since the tire side itself is limited to move within a certain range by the pre-limited roller group 83, the tire side automatically returns to the moving stroke of the conveying roller group 823 after being lifted and moved downward to continue the correction. At this time, the conveying roller group 823 also returns to the initial position. When in use, the sidewalls are respectively passed through the pre-limiting roller set 83 and the material picking roller 842 and then placed on the conveying and adjusting mechanism 82 .

[0047] It should be noted that the detection element 81 and the adjustment drive source 822 and the conveying roller group 823 in the conveying adjustment mechanism 82 of the present invention are two groups, which are used to perform real-time conveying position correction on the two sidewalls at the same time. Due to the different specifications of tires, the width and position of the sidewalls on the support component 12 are different, that is, the position of the detection element 81 needs to be adjusted when producing tires of different specifications.
