Description

Technical Field

[0001] The present invention relates to the technical field of automatic feeding, and particularly relates to a feeding device for tire laminated materials and a control method thereof. Background Art

[0002] In the processing process of tire forming, various raw materials are first processed into laminated materials, and subsequent processing is mostly the lamination of various laminated materials. Some specifications of tires require the lamination of nylon bead. At present, there are mainly two forms of nylon bead lamination. One is that workers manually tear the nylon material roll and then manually paste it onto the tire body drum. The other is that the nylon material roll is unrolled and then transported to the tire body drum through a feeding rack for lamination. With the improvement of automation, automatic feeding and lamination better meet the requirements of improving the overall machine efficiency.

[0003] However, the existing feeding structures for various laminated materials have the following problems: during the lamination process, the nylon feeding rack has telescopic movements, resulting in easy stretching and wrinkling of the nylon rubber material. Specifically, in the "Tire Forming Machine Tire Body Drum Feeding Rack and Its Implementation Method" provided by the invention patent application CN106696320A, a wire bead wrapper conveying device 5 is driven by a brake cylinder 55 to reciprocate to achieve feeding. The reciprocating movement causes the conveying device 5 itself to have telescopic movements, directly resulting in material stretching or wrinkling; or, as in the "Cord Feeding Rack for Tire Production" provided by the invention patent CN106696323B, the conveying mechanism 21 includes a front conveying roller 211, a rear conveying roller 212, and a floating conveying plate 23. The floating conveying plate 23 is arranged between the front conveying roller 211 and the rear conveying roller 212. The floating conveying plate 23 can reduce the friction between the cord and the conveying plate, thereby reducing the stretching amount of the cord caused by friction. The stretching amount can be reduced but not completely solved, and there is uncontrollability. It can be seen that the existing technology cannot completely solve the problems of stretching and wrinkling of laminated materials.

[0004] Therefore, the existing feeding devices for laminated materials such as nylon bead wrappers have problems of stretching and wrinkling. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing feeding devices for laminated materials such as nylon bead wrappers have problems of stretching and wrinkling.

[0008] The swing mechanism includes a driving member and a swing frame. The swing frame is connected to the second conveying member. The driving member is activated to cause the swing frame to drive the second conveying member to rotate independently relative to the first conveying member.

[0012] A balance guiding member. The driving members are arranged in pairs. The balance guiding member is placed between the two driving members. The driving members and the balance guiding member are arranged on a straight line and have a distance from the rotating shaft.

[0013] In another preferred embodiment, the swing frame is provided with:

[0014] A hoisting frame, and the free end of the driving member is connected to the hoisting frame;

[0015] A pressing roller is provided on one side of the hoisting frame close to the carcass drum; and,

[0016] A third conveying member passes through the hoisting frame, and the output end of the third conveying member is placed below the pressing roller.

[0017] In another preferred embodiment, the first conveying member has two arranged side by side. The two first conveying members are respectively slidably provided on the first conveying frame. The corresponding first conveying member and the second conveying member are respectively connected, and the first conveying member moves synchronously with the second conveying member.

[0018] In another preferred embodiment, the second conveying frame is provided with a connecting plate. A space for the layered material to pass through is formed between the connecting plate and the second conveying frame. The connecting plate is connected with a slider, and the slider is slidably provided on the second conveying frame.

[0019] In another preferred embodiment, the second conveying frame includes:

[0020] The first cross beam, the rotating ends are arranged in pairs and are provided at both ends of the first cross beam;

[0021] The second cross beam, the telescopic members are arranged in pairs and are provided at both ends of the second cross beam, the two second conveying members are respectively slidably provided on the first cross beam and the second cross beam, and limiting blocks are provided at both ends of the first cross beam and the second cross beam; and,

[0022] At least one connecting beam, the connecting beam is connected between the first cross beam and the second cross beam.

[0023] In another preferred embodiment, it further includes a pay-off mechanism, and the pay-off mechanism includes:

[0024] The pay-off base, which is provided with a slide rail; and,

[0025] The first pay-off member and the second pay-off member are respectively slidably provided on the slide rail.

[0026] The present invention also provides a control method for a feeding device of the above-mentioned tire layered material, including the following steps:

[0028] The layered material reaches the carcass drum via the first conveying member and the second conveying member and realizes fitting;

[0029] After fitting at one position, the power member of the second conveying member drives the two second conveying members to move in a separating and combining manner, and after positioning to the set position, fitting is carried out again.

[0030] It can be seen from the above technical solutions that the advantages and positive effects of the feeding device of the tire layered material and its control method of the present application are as follows: Compared with the prior art, the present invention uses the first conveying member for the primary transmission of the layered material, drives the second conveying member to rotate through the swing frame, and uses the rotation angle of the second conveying member to adapt to the fitting position.

The layered material passes through the first conveying member and the second conveying member and directly reaches the fitting position of the carcass drum. During the entire conveying and fitting process, there is no relative movement between the layered material and the first conveying member and the second conveying member. Therefore, problems such as local stretching or wrinkling will not occur, and the conveying efficiency and fitting accuracy are greatly improved. Description of the Drawings

Detailed implementation manners

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by this application. The feeding device for tire laminate materials and its control method provided by the present invention do not have the problem of local stretching or wrinkling, greatly improving the conveying efficiency and fitting accuracy. The following will make a detailed description of the present invention with reference to the specification drawings and specific embodiments.

[0042] To overcome the problem that the feeding device for tire laminate materials in the prior art is prone to stretching and wrinkling, refer to Figure 1 and Figure 2 , the present invention provides a feeding device for tire laminate materials, including a conveying mechanism 10 and a swinging mechanism 20. The conveying mechanism 10 includes a first conveying member 11 and a second conveying member 12, and the second conveying member 12 is independently rotatable relative to the first conveying member 11. The swinging mechanism 20 includes a driving member 21 and a swinging frame 22. The swinging frame 22 is connected to the second conveying member 12, and the driving member 21 is activated to drive the swinging frame 22 to drive the second conveying member 12 to rotate independently relative to the first conveying member 11. The laminate material passes through the first conveying member 11 and the second conveying member 12 in sequence and is then fitted to the carcass drum 40.

[0043] In the present invention, the first conveying member 11 is used for the primary transmission of the laminate material. The swinging frame 22 drives the second conveying member 12 to rotate, and the rotation angle of the second conveying member 12 is used to adapt to the fitting position. Compared with the conveying structure of the prior art, the angle of the second conveying member 12 can be pre-adjusted according to parameters such as the thickness of the laminate material to be fitted, and then the conveying process is started, without the need for large-scale adjustment of the entire feeding device, thereby reducing the adjustment time for changing specifications and improving production efficiency. The laminate material passes through the first conveying member 11 and the second conveying member 12 and directly reaches the fitting position of the carcass drum 40. Since the angle of the second conveying member 12 is adjusted first and then the conveying process is started, during the entire conveying and fitting process, the first conveying member 11 and the second conveying member 12 only have conveying actions and no other telescopic, lifting, etc. actions. Therefore, there is no relative movement between the laminate material and the first conveying member 11 and the second conveying member 12, and thus there is no problem of local stretching or wrinkling, greatly improving the conveying efficiency and fitting accuracy.

[0044] Specifically, the driving member 21 can adopt a servo electric cylinder, which can accurately control the lifting height of the swinging frame 22 and has good stability. The first conveying member 11 and the second conveying member 12 can adopt conveyor belts to transport the laminate material.

[0045] Refer to Figure 2 In a preferred embodiment, the first conveyor member 11 is provided on the first conveyor frame 111, the second conveyor member 12 is provided on the second conveyor frame 121, and the second conveyor frame 121 includes a rotating end 1211 and a free end 1212. The rotating end 1211 is rotatably provided on the swing frame 22. An expansion member 124 is provided between the free end 1212 and the swing frame 22 to adjust the distance between the second conveyor member 12 and the swing frame 22. The first conveyor member 11 and the second conveyor member 12 each have their own mounting carriers (the first conveyor frame 111 and the second conveyor frame 121), which can improve the structural stability of the overall device. In this embodiment, the second conveyor member 12 rotates with the swing frame 22 through the second conveyor frame 121, and in addition, it can also rotate independently of the swing frame 22. Specifically, in order to adapt to the movement requirements of the second conveyor member 12, the second conveyor frame 121 needs to have a stable rotation center. Therefore, the rotating end 1211 is arranged on the swing frame 22, and the expansion member 124 is arranged at the free end 1212 of the second conveyor frame 121. The second conveyor member 12 rotates with the swing frame 22 to align the fitting position of the second conveyor member 12 with the carcass drum 40, and the elongation of the expansion member 124 is to adjust the distance between the second conveyor member 12 and the swing frame 22, facilitating the staff to observe and detect the materials to be fitted, and ensuring the alignment and correct fitting of the materials. Among them, the expansion amount of the expansion member 124 can be set as a fixed value, and the expansion member has two working positions: retraction and elongation; the expansion amount can also be set as a variable value, enabling the expansion member 124 to be fixed at multiple positions.

[0046] Specifically, the specific form of the expansion member 124 can be a cylinder, an oil cylinder, an electric push rod, etc., as long as it can achieve the adjustment of the distance between the second conveyor member 12 and the swing frame 22.

[0047] Refer to Figure 1 and 4 Or further, in the above embodiment, the swing frame 22 is provided with a rotating shaft 23 and a balance guiding member 24. The rotating end 1211 of the second conveyor frame 121 is hinged to the rotating shaft 23. The balance guiding members 24 are arranged in pairs, and the driving member 21 is placed between the two balance guiding members 24. The driving member 21 and the balance guiding members 24 are arranged on a straight line and have a distance from the rotating shaft 23. With the synergistic effect of the driving member 21 and the balance guiding members 24, the rotation of the swing frame 22 is more stable, avoiding the jitter caused by inertia and further improving the conveying accuracy. The rotating shaft 23 of the swing frame 22 provides a stable rotation axis for the second conveyor frame 121, but the swing frame 22 itself also has a lifting movement. Using the lever principle to design the distance between the driving member 21 and the rotating shaft 23, this distance is the lever arm of the lever structure, so as to maintain a good moment balance and reduce energy loss.

[0048] Refer to again Figure 1, or further, in the above embodiment, the swing frame 22 is provided with a hoisting frame 221, a pressing roller 222 and a third conveying member 25. The free end of the driving member 21 is connected to the hoisting frame 221. The pressing roller 222 is arranged on one side of the hoisting frame 221 close to the carcass drum 40. The third conveying member 25 passes through the hoisting frame 221, and the output end of the third conveying member 25 is placed below the pressing roller 222. In addition to the lifting function, the swing frame 22 can also convey the second type of layered material to realize the lamination of multiple layers of materials of the carcass. The driving member 21 is arranged on the hoisting frame 221 without affecting the conveyance of the second type of layered material. The pressing roller 222 can adjust the pressure to ensure that the layered material is closely laminated and improve the lamination quality.

[0049] Refer to Figure 2 and 3 , further, in the above embodiment, there are two second conveying members 12 arranged side by side. The second conveying frame 121 is provided with a power member 122. Each of the two second conveying members 12 is provided with a driven member. When the power member 122 operates, each driven member drives the two second conveying members 12 to translate synchronously towards or away from each other. In practical applications, layered materials such as nylon bead flipper may have different widths. To adapt to this change, the present invention designs two second conveying members 12 with adjustable spacing. The two second conveying members 12 are arranged side by side, and each of them is connected with a driven member. When the power member 122 is started, it can drive the two driven members to act, so that the two second conveying members 12 translate synchronously towards or away from each other. This design allows for fine adjustment according to the width of the layered material to ensure the stability of the material during conveyance, avoid deviation or wrinkles. In addition, the synchronous action of the two second conveying members 12 also ensures the uniformity and accuracy of the layered material during lamination. Specifically, the power member 122 can adopt a servo motor, and the two driven members can adopt a left-handed nut and a right-handed nut, and are connected to the driven members through transmission mechanisms such as left and right hand ball screws 123 to achieve precise translation control. The servo motor has the characteristics of fast response speed, high positioning accuracy and stable operation, and can meet the requirements for precise conveyance of layered materials.

[0050] Refer to Figure 2 and 3, Further, in the above embodiment, there are also two first conveying members 11 arranged side by side. The two first conveying members 11 are respectively slidably arranged on the first conveying rack 111. The corresponding first conveying member 11 and the second conveying member 12 are respectively connected, and the first conveying member 11 moves synchronously with the second conveying member 12. Since in the production process of tires, the nylon bead cover is symmetrically attached to both sides of the tire, two nylon bead covers need to be attached simultaneously each time to ensure symmetry and attachment accuracy. The design of the first conveying member 11 enables it to move synchronously with the second conveying member 12, further ensuring the stability of the attachment process. Specifically, the first conveying member 11 and the second conveying member 12 are connected by a synchronous belt to ensure synchronous movement. Moreover, the first conveying member 11 and the second conveying member 12 can also be connected by a rotatable side plate, enabling the two to move synchronously in the direction perpendicular to the conveying trajectory on the basis of relative rotation.

[0051] Refer to Figure 3 , Further, in the above embodiment, the second conveying rack 121 is provided with a connecting plate 1201. A space for the layered material to pass through is formed between the connecting plate 1201 and the second conveying rack 121. The connecting plate 1201 is connected with a slider, and the slider is slidably arranged on the second conveying rack 121. In order to avoid trajectory interference between the swinging mechanism 20 and other mechanisms, in this embodiment, the swinging mechanism 20 is placed above the second conveying member 12, and the second conveying rack 121 is used as an intermediate connecting member and placed above the second conveying member 12. The second conveying member 12 is usually a conveyor belt, a conveyor roller, etc. The design of the connecting plate 1201 should not affect the passage of the layered material to ensure the rationality of the space design. Specifically, each of the two second conveying members 12 is provided with at least one connecting plate 1201, which is connected to the second conveying rack 121 to ensure the stability of the connection. Moreover, the connecting plate 1201 is slidably arranged on the second conveying rack 121 through the slider, ensuring that the distance between the two second conveying members 12 is adjustable and the sliding is stable. The connecting plate 1201 and the slider structure of this embodiment provide a guiding function for the translation of the second conveying member 12 while ensuring stable connection.

[0052] Refer to Figure 4 , A baffle 1202 is provided on the input side of the first conveying member 11, which is used for positioning and guiding the layered material about to be conveyed onto the conveying mechanism 10. A plurality of positioning rollers are arranged inside the baffle 1202.

[0053] Refer to Figure 3, or further, in the above embodiment, the second conveying frame 121 includes a first cross beam 1213, a second cross beam 1214 and at least one connecting beam 1215. The rotating ends 1211 are arranged in pairs and are provided at both ends of the first cross beam 1213. The telescopic members 124 are arranged in pairs and are provided at both ends of the second cross beam 1214. The two second conveying members 12 are respectively slidably arranged on the first cross beam 1213 and the second cross beam 1214. As the installation carrier of the second conveying member 12, the structure of the second conveying frame 121 should be simplified as much as possible to improve the stability of the overall mechanism and the operation convenience. In order to distinguish the positions of the rotating end 1211 and the free end 1212, the first cross beam 1213 and the second cross beam 1214 are respectively provided, and are firmly connected by the connecting beam 1215 to ensure the accurate positioning of the rotating end 1211 and the free end 1212. The power member 122 is installed on the connecting beam 1215 to drive the two second conveying members 12 to translate. The overall structure is compact and the operation is simple. Limit blocks 1216 are provided at both ends of the first cross beam 1213 and the second cross beam 1214 to prevent the second conveying member 12 from translating excessively. Combining the above embodiment, there are 3 connecting beams, and the power member 122 is arranged on the middle connecting beam 1215.

[0054] Refer to Figure 2 , in another preferred embodiment, the present invention further includes a pay-off mechanism 30. The pay-off mechanism 30 includes a pay-off base 31, a first pay-off member 321 and a second pay-off member 322. The pay-off base 31 is provided with a slide rail, and the first pay-off member 321 and the second pay-off member 322 are respectively slidably arranged on the slide rail. The accurate pay-off and positioning of the layered material are realized through the pay-off mechanism 30 to ensure that the material remains flat during the conveying process, and further improve the laminating accuracy and efficiency. The designs of the first pay-off member 321 and the second pay-off member 322 are suitable for the conveying of two symmetrical materials, especially nylon bead cover cloth. The pay-off mechanism 30 is firmly supported by the pay-off base 31, and the first pay-off member 321 and the second pay-off member 322 respectively slide on the pay-off base 31, which can adapt to the large change in the inner edge distance of the nylon bead when different specifications of tires are used.

[0055] Refer to Figure 5 and Figure 6, the structure of the present invention can be applied to the entire carcass feeding device. This patent is arranged directly below the carcass feeding rack and above the feeding guide rail 70. The two devices, namely the steel cord bead automatic cutting and feeding device 50 and the chafer feeding device 60, are arranged at both ends of the feeding guide rail 70 and can be translated on the feeding guide rail 70. In actual implementation, the left and right positions can be interchanged. The fitting height of the second conveyor 12 is controlled by the swing mechanism 20, which can avoid the steel cord bead and the chafer fitting rack. The present invention optimizes the layout compared with the traditional structure. When using this application for the feeding of nylon wrapper, in the non-working state, there is a distance in height from the steel cord bead automatic cutting and feeding device 50 and the chafer feeding device 60, and there is no trajectory interference. In the working state, it can avoid the trajectory ranges of the two through the swing mechanism 20. The layout is reasonable and the degree of automation is high.

[0056] The present invention also provides a control method for a feeding device of a tire laminated material, including the following steps:

[0057] The driving member 21 operates, the swing frame 22 drives the second conveyor 12 to rotate, and the free end of the second conveyor 12 rotates to the fitting position of the carcass drum 40;

[0058] The laminated material reaches the carcass drum 40 via the first conveyor 11 and the second conveyor 12 and realizes fitting.

[0059] In actual production, the detailed specific steps are as follows:

[0060] Step 1, nylon bead unwinding: According to the spacing requirements of the left and right nylon bead wrappers in the tire process, adjust the first unwinding member 321 and the second unwinding member 322 to the appropriate spacing;

[0061] Step 2, positioning to the fitting position of the carcass drum 40: The steel cord bead automatic cutting and feeding device 50 and the chafer feeding device 60 retract to the waiting position, the telescopic member 124 of the second conveyor 12 extends, and the driving member 21 of the swing frame 22 aligns the free end of the second conveyor 12 with the fitting position of the carcass drum 40;

[0062] Step 3, fitting the nylon bead: After the nylon bead compound is unwound, it goes onto the conveyor belt through the edge 1202 of the first conveyor 11, and the conveyor belt conveys and fits the nylon bead to the carcass drum 40.

[0063] Step 4, misfitting of the nylon bead: When there is a need for misfitting, after fitting the nylon bead at one position, the power member 122 of the second conveyor 12 drives the two second conveyors 12 to separate and combine and translate. After positioning to the set position, fitting is performed again.

[0064] In summary, for the feeding device of the tire laminate material and its control method of the present invention, through the cooperation of the conveying mechanism 10 and the swinging mechanism 20, the automatic feeding and laminating of the laminate material are realized, the problems of stretching and wrinkling of the laminate material during the laminating process are avoided, the laminating accuracy and quality are improved, at the same time, the adjustment time for changing specifications is reduced, and the production efficiency is increased.
