Description

Technical Field

[0001] The invention relates to the field of tire production equipment, and in particular to an automatic rubber joint device. Background Art

[0002] The belt layer plays a vital role in the tire production process. The production of the belt layer is to cut the steel cord into cord strips according to the angle and width required by the tire process, and then the cord strips are fed, spliced, unloaded, and then wrapped and attached to the edge, and finally rolled onto the trolley. With the market demand for giant tires and process innovation, the belt layer width continues to increase and the angle continues to decrease.

[0003] There are usually two ways to connect small-angle giant tire joints because the angle is too small, the length of the belt layer's bevel is long, and the width of the belt layer increases. One is to use the joint as the power joint to drive the feeding conveyor belt and the unloading conveyor belt with the strip telescopic belt as the main structure to complete the splicing action. In this way, the minimum rotation angle of the joint can only be 15°, and when the angle is less than 20°, the two outermost strip belt frames will be skewed, resulting in inaccurate feeding accuracy. The second is to use a full-steel small-angle cutting machine joint form, and the inertia force of the feeding conveyor belt drives the cord to the joint splicing position to complete the splicing action. This type of joint can only meet the splicing of materials with a cutting width of less than 400 and a cutting angle of more than 15°. When the cutting width is greater than 400 and the cutting angle is less than 15°, the cord cannot be sent to the joint splicing position by the inertia force of the feeding conveyor belt alone, which does not meet the giant tire process requirements.

[0004] In response to the special requirements of small-angle giant tires for the angle and width of the belt layer, the steel cord used in it has a smaller angle, usually less than 15°, and a wider cutting width, usually greater than 700mm, than that used in traditional tires. The two existing joint methods cannot meet the process requirements for angle and width of small-angle giant tires.

[0005] Therefore, there is a problem in the prior art that the joint equipment cannot meet the production requirements of small-angle rubber joints for giant tires. Summary of the invention

[0010] Furthermore, when the joint assembly is located at the set position, the joint assembly divides the first area into a lifting area and a static area. The lifting area is farther away from the second conveying assembly relative to the static area, and the first lifting portion located in the lifting area lifts or lowers the rubber.

[0011] Furthermore, the first lifting part and the second lifting part each include a plurality of lifting members and a plurality of driving members, the driving members are arranged on the first conveying assembly, the driving members are drivingly connected to the lifting members and drive the lifting members to move in a direction approaching or away from the joint assembly.

[0012] Further, the number of lifting members and driving members of the first lifting part is equal and corresponds one to one; and / or each driving member of the second lifting part is drivingly connected to at least one different lifting member.

[0013] Furthermore, the multiple lifting members of the second lifting portion are divided into multiple groups, and the multiple groups of lifting members are arranged at intervals along the length direction of the first conveying component, and the lifting members in the same group are drivingly connected to the same driving member.

DETAILED DESCRIPTION

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0029] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0030] In order to solve the problem that the joint equipment in the prior art cannot meet the production requirements of small-angle rubber joints for giant tires, the present application provides an automatic rubber joint device.

[0031] like Figures 1 to 5 As shown, the automatic rubber joint device in the present application includes a first conveying assembly 10, a second conveying assembly 20, a joint assembly 30 and a lifting assembly 40. The first conveying assembly 10 and the second conveying assembly 20 are sequentially linked in the length direction, and the conveying directions of the first conveying assembly 10 and the second conveying assembly 20 are the same, and in the conveying directions of the first conveying assembly 10 and the second conveying assembly 20, the first conveying assembly 10 is located downstream of the second conveying assembly 20; the joint assembly 30 is movably arranged above one end of the first conveying assembly 10 close to the second conveying assembly 20, and the angle between the joint direction of the joint assembly 30 and the conveying direction of the first conveying assembly 10 is adjustable; at least a part of the lifting assembly 40 is movably arranged on the side of the first conveying assembly 10 facing the joint assembly 30, and in the height direction, the lifting assembly 40 can move in the direction close to or away from the joint assembly 30 to lift or put down the rubber on the first conveying assembly 10.

[0032] When the rubber material automatic joint device in the present application is used to joint two pieces of rubber material, the two pieces of rubber material can be conveyed by the second conveying assembly 20. When the first piece of rubber material is fully conveyed to the first conveying assembly 10, the lifting assembly 40 can lift the first piece of rubber material completely. When the second piece of rubber material moves to the joint position corresponding to the joint assembly 30, the lifting assembly 40 can put down the first piece of rubber material and complete the joint operation of the two pieces of rubber material through the joint assembly 30. In the present application, since the joint angle of the joint assembly 30 can be adjusted, the joint operation of rubber materials at different angles can be realized. In addition, since the lifting assembly 40 can be used to lift the first piece of rubber material before the joint, the problem of inaccurate feeding accuracy caused by the tilt of the frame when the joint angle is less than 20° in the prior art can be effectively avoided. At the same time, the movement of the two pieces of rubber material simultaneously driven by the first conveying assembly 10 and the second conveying assembly 20 can effectively solve the technical problem that the cord fabric cannot be delivered to the joint splicing position by the inertia force of the feeding conveyor belt in the prior art, and does not meet the requirements of the giant tire process. Therefore, the automatic rubber joint device in the present application effectively solves the problem that the joint equipment in the prior art cannot meet the production requirements of small-angle rubber joints for giant tires.

[0033] That is to say, in the present application, the first conveying assembly 10 is equivalent to the joint conveyor belt in the prior art, and the second conveying assembly 20 is equivalent to the feeding conveyor belt in the prior art.

[0034] It should be noted that the small angle in this application generally refers to a stitching angle of less than 15°. The rubber material used to produce giant tires in this application generally refers to a belt layer with a width greater than 700 mm.

[0035] like Figure 1 As shown, for Figure 1 As for the arrangement of the first conveying assembly 10 and the second conveying assembly 20 , the conveying directions of the first conveying assembly 10 and the second conveying assembly 20 are both from right to left, and the first conveying assembly 10 is located on the left side of the second conveying assembly 20 .

[0036] It should be noted that when the rubber materials are joined, the ends of the two rubber materials that are close to each other are actually joined, that is, the end of the rubber material at the downstream position of the first conveying component 10 and the head of the rubber material at the upstream position are joined. In addition, in this embodiment, the lifting component 40 only lifts or lowers the rubber material at the downstream position of the first conveying component 10 among the two rubber materials, and does not lift or lower the other rubber material.

[0037] In a specific embodiment of the present application, the joint assembly 30 has a first angle position and a second angle position relative to the first conveying assembly 10. When the joint assembly 30 is adjusted relative to the first conveying assembly 10, the joint assembly 30 switches between the first angle position and the second angle position. When the joint assembly 30 is at the first angle position, the angle between the joint direction of the joint assembly 30 and the conveying direction of the first conveying assembly 10 is smaller than the angle between the joint direction of the joint assembly 30 and the conveying direction of the first conveying assembly 10 when the joint assembly 30 is at the second angle position. In other words, when the joint assembly 30 is at the first angle position, the joint angle of the joint assembly 30 is the smallest at this time, and when the joint assembly 30 is at the second angle position, the joint angle of the joint assembly 30 is the largest at this time. Therefore, in the present application, the angle adjustment range of the joint assembly 30 is between the first angle position and the second angle position.

[0038] exist Figure 3 In the illustrated embodiment, the two lines marked by A in the figure are the first angular position and the second angular position.

[0039] In a specific embodiment of the present application, the lifting assembly 40 includes a first lifting portion 41 and a second lifting portion 42, the first lifting portion 41 is movably arranged in the first area 14 of the first conveying assembly 10, and the second lifting portion 42 is arranged in the second area 15 of the first conveying assembly 10, the first area 14 is the projection area of ​​the joint assembly 30 on the first conveying assembly 10 when the joint assembly 30 is adjusted relative to the first conveying assembly 10, or the joint assembly 30 in the present application is adjusted in the first area 14, and the second area 15 is located in the area of ​​the first area 14 away from the second conveying assembly 20. It should be noted that since the rubber automatic joint device in the present application is mainly to meet the production process requirements of giant tires, the width of the rubber is generally greater than 700mm, which will cause the transported rubber to be heavier. Therefore, if the joint angle of the two pieces of rubber is small, when the first piece of rubber located in front in the conveying direction of the first conveying assembly 10 and the second conveying assembly 20 moves to the first conveying assembly 10, it may cause uneven force on the first conveying assembly 10. Therefore, by providing the lifting assembly 40, a certain supporting effect can be provided to the rubber material on the first conveying assembly 10, thereby solving the problem in the prior art that the belt frame may be skewed, resulting in inaccurate feeding accuracy.

[0040] Furthermore, it should be noted that in the present application, the first region 14 is determined according to the angle adjustment range of the joint assembly 30, rather than limiting the adjustment range of the joint assembly 30 according to the first region 14. In other words, when the angle adjustment range of the joint assembly 30 is different, the area of ​​the first region 14 of the first conveying assembly 10 is different.

[0041] Specifically, when the joint assembly 30 is located at the set position, the joint assembly 30 divides the first area 14 into a lifting area and a static area. The lifting area is farther away from the second conveying assembly 20 relative to the static area, and the first lifting portion 41 is located in the lifting area to lift or lower the rubber. In other words, for two pieces of rubber that need to be connected, the area where the tail of the rubber in the front is located is the lifting area, and the area where the tail of the rubber in the rear is located is the static area. Therefore, in the present application, the lifting assembly 40 only lifts or lowers the first piece of rubber in the front on the first conveying assembly 10.

[0042] In the above embodiment, different positions of the first rubber material can be lifted respectively by setting the first lifting portion 41 and the second lifting portion 42. Moreover, according to the above setting method, it can be seen that in the present application, the first lifting portion 41 is mainly used to lift or lower the tail of the first rubber material, so when the angle of the joint changes, the area of ​​the corresponding tail of the first rubber material will change, or the area of ​​the lifting area and the area of ​​the static area will change, so at this time, it is necessary to increase or reduce the moving part of the first lifting portion 41.

[0043] In a preferred embodiment of the present application, the first lifting portion 41 can be connected to the joint assembly 30 by signal, so as to ensure that when the joint angle of the joint assembly 30 changes, the part lifted by the first lifting portion 41 can be changed accordingly. Of course, in the present application, the control of the first lifting portion 41 and the second lifting portion 42 can also be manually controlled and adjusted by the operator.

[0044] Alternatively, if Figure 4 and Figure 5 As shown, the first lifting part 41 and the second lifting part 42 each include a plurality of lifting members 43 and a plurality of driving members 44, the driving member 44 being arranged on the first conveying assembly 10, the driving member 44 being drivingly connected with the lifting member 43 and driving the lifting member 43 to move in a direction close to or away from the joint assembly 30. In the present application, the first lifting part 41 and the second lifting part 42 respectively drive the lifting member 43 to move through the driving member 44, thereby driving the rubber material to move through the lifting member 43, thereby realizing the lifting or putting down of the rubber material. Further optionally, the lifting member 43 is made of carbon steel material. And, in the present application, the driving member 44 can be a cylinder. Of course, in addition to using a cylinder, other components can also be used instead of the driving member 44.

[0045] In a specific embodiment of the present application, Figure 4 and Figure 5As shown, the number of lifting members 43 and driving members 44 of the first lifting part 41 is equal and corresponds to each other; and each driving member 44 of the second lifting part 42 is respectively connected to at least one different lifting member 43. In the present application, when the joint angle of the two rubber materials changes, it is necessary to adjust the moving part of the first lifting part 41, that is, it is necessary to adjust the number of movements of the lifting members 43 of the first lifting part 41. Therefore, by setting the number of lifting members 43 and driving members 44 of the first lifting part 41 to be equal and correspond to each other, the first lifting part 41 can be accurately adjusted, so as to ensure the lifting effect of the rubber material, or ensure that the moving lifting parts can all contact with the rubber material to ensure that the first lifting part 41 will not lift the second rubber material located at the upstream position, thereby ensuring the joint effect of the head and tail parts of the two rubber materials. Preferably, the multiple lifting members 43 of the second lifting part 42 are divided into multiple groups, and the multiple groups of lifting members 43 are arranged at intervals along the length direction of the first conveying assembly 10, and the lifting members 43 in the same group are connected to the same driving member 44. In this embodiment, for the second lifting part 42, when the joint angle of the two pieces of rubber changes, since there is no need to adjust the number of movable lifting members 43 of the second lifting part 42, the multiple lifting members 43 of the second lifting part 42 are divided into multiple groups, and the multiple groups of lifting members 43 are arranged at intervals along the length direction of the first conveying assembly 10, and the lifting members 43 in the same group are connected to the same driving member 44, which can effectively control the lifting height of the lifting members 43 in the same group, thereby ensuring that the rubber will not tilt after being lifted by the second lifting part 42, thereby ensuring the joint effect of the two pieces of rubber, and the rubber will not tilt during the conveying process.

[0046] That is to say, in the present application, for the first lifting portion 41, each lifting member 43 and each driving member 44 of the first lifting portion 41 are controlled separately, and each lifting member 43 can move independently relative to other lifting members 43. For the second lifting portion 42, each group of lifting members 43 and driving members 44 moves independently, that is, the lifting members 43 of the same group move simultaneously.

[0047] In a specific embodiment of the present application, the first conveying assembly 10 includes a conveying frame 11 and a conveyor belt 12. The driving member 44 of the first lifting portion 41 and the driving member 44 of the second lifting portion 42 are respectively arranged on the conveying frame 11; there are multiple conveyor belts 12, and the multiple conveyor belts 12 are arranged at intervals along the width direction of the conveying frame 11, and there is a lifting gap between two adjacent conveyor belts 12, and the lifting member 43 of the first lifting portion 41 and the lifting member 43 of the second lifting portion 42 can extend out from the lifting gap. That is to say, in this embodiment, when the first conveying assembly 10 conveys the rubber material, the multiple conveyor belts 12 move relative to the conveying frame 11 in the conveying direction of the first conveying assembly 10 at the same time, and the first conveying assembly 10 conveys the rubber material through the conveyor belts 12. At the same time, since the rubber material needs to be lifted by the first lifting part 41 and the second lifting part 42, the lifting gap is set between two adjacent conveyor belts 12 to effectively ensure that the rubber material can be lifted by the first lifting part 41 and the second lifting part 42, and at the same time, the first lifting part 41 and the second lifting part 42 can be effectively prevented from contacting the conveyor belt 12 during the movement, or the conveyor belt 12 can be effectively prevented from hindering the movement of the first lifting part 41 and the second lifting part 42. It should be noted that in the present application, the structures of the first conveyor assembly 10 and the second conveyor assembly 20 can be the same, or the first conveyor assembly 10 and the second conveyor assembly 20 can be combined into one.

[0048] In the above embodiment, a pad 13 can be added above the conveying frame 11, and the pad 13 is located between the conveying frame 11 and the conveyor belt 12. At the same time, the first lifting component 40 can be set on the pad 13, and the second lifting component 40 can be set on the conveying frame 11. For such a setting method, two different technical effects can be achieved. One is that under the condition that the heights raised by the first conveying component 10 and the second conveying component 20 are the same, since the pad 13 has raised the height of the first lifting component 40, the energy consumed by the first lifting component 40 can be reduced. The second is that under the condition that the heights raised by the first conveying component 10 and the second conveying component 20 are the same, since the pad 13 has raised the height of the first lifting component 40, the height of the tail of the rubber material raised by the first component can be higher than the height of the other parts of the rubber material, thereby ensuring that the two rubber materials can be more easily connected. Of course, in the actual use process, the heights of the first lifting component 40 and the second lifting component 40 after lifting can be set according to the actual production process needs.

[0049] Specifically, the joint assembly 30 includes a main body 31, a drive seat 32 and a rotation center seat 33. At least a part of the main body 31 is movably arranged above the first conveying assembly 10, and the angle between the joint direction of the main body 31 and the conveying direction of the first conveying assembly 10 is adjustable; the two ends of the main body 31 are respectively connected to the two ends of the drive seat 32 and the rotation center seat 33, and the main body 31 can rotate relative to the drive seat 32 and the rotation center seat 33. Such an arrangement can drive the main body 31 through the drive seat 32, and the main body 31 can move along the drive seat 32 and rotate relative to the rotation center seat 33. Preferably, the main body 31 can be connected to the rotation center seat 33 through a connecting rod mechanism or other structure.

[0050] In an optional embodiment of the present application, the driving seat 32 and the rotating center seat 33 are respectively arranged at both ends of the length direction of the first conveying assembly 10 and are approximately arranged along the diagonal line of the first conveying assembly 10. In addition, the rotating center seat 33 can be arranged below the first conveying assembly 10. Of course, the actual setting positions of the driving seat 32 and the rotating center seat 33 in the present application can also be adjusted according to specific production conditions, as long as it can ensure that the main body 31 can smoothly connect the two pieces of rubber.

[0051] Optionally, the joint assembly 30 further includes an angle detection member 34 and an encoder 35, wherein the angle detection member 34 is disposed on the driving seat 32; and the encoder 35 is disposed on the rotating center seat 33. In the present application, the encoder 35 is mainly used to control the angle rotation of the main body 31, and the angle detection member 34 is provided to ensure that the main body 31 does not exceed the limit angle during the angle adjustment process, thereby ensuring the stable operation of the rubber material automatic joint device.

[0052] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when the automatic rubber joint device in the present application is used to joint two pieces of rubber, the two pieces of rubber can be transported through the second conveying component 20, and when the first piece of rubber is completely transported to the first conveying component 10, the lifting component 40 can lift the first piece of rubber completely, and when the second piece of rubber moves to the joint position corresponding to the joint component 30, the lifting component 40 can put down the first piece of rubber and complete the joint operation of the two pieces of rubber through the joint component 30. In the present application, since the joint angle of the joint component 30 can be adjusted, the joint operation of rubber at different angles can be realized. In addition, since the lifting component 40 can be used to lift the first piece of rubber before the joint, the problem of inaccurate feeding accuracy caused by the skewness of the frame when the joint angle is less than 20° in the prior art can be effectively avoided. At the same time, by driving the two rubber materials to move simultaneously through the first conveying assembly 10 and the second conveying assembly 20, it is possible to effectively solve the technical problem in the prior art that the cord fabric cannot be delivered to the joint splicing position by relying solely on the inertial force of the feeding conveyor belt, and does not meet the technical requirements of the giant tire process. Therefore, the rubber material automatic joint device in the present application effectively solves the problem that the joint equipment in the prior art cannot meet the production requirements of small-angle rubber material joints for giant tires.

[0053] The outstanding feature of the present invention is that the feeding, jointing and unloading actions can be realized on the same strip conveyor belt 12, and the lifting assembly 40 is used to realize the automatic splicing of materials less than 15°. When the joint assembly 30 rotates around the center to change the angle, the lifting assembly 40 switches the lifting part of the corresponding angle according to the joint angle. When the material is incoming, the tail of the material is lifted according to the different angles of the material to wait for feeding. After the feeding material is in place, the lifting assembly 40 falls, and the automatic joint device performs the joint. After the joint is completed, the conveyor belt is unloaded. To change the process angle, only the joint assembly 30 needs to be rotated, which improves the mechanical repeat positioning accuracy and meets the manufacturing process requirements of the giant tire belt layer; the feeding, jointing and unloading actions are realized on the same belt, which solves the disadvantage that wide materials cannot be delivered to the joint position, and greatly improves the joint efficiency; at the same time, the automation level of the giant tire small angle cutting machine is improved.

[0054] Obviously, the embodiments described above are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
