Description

Technical Field

[0001] This invention relates to the field of tire production equipment, and more specifically, to an automatic rubber compound splicing device. Background Technology

[0002] In tire manufacturing, the cord layer plays a crucial role. The production of the cord layer involves cutting steel cord fabric into strips according to the required angles and widths for tire manufacturing. These strips are then fed, spliced, unloaded, edge-wrapped, and finally wound onto a trolley. With increasing market demand for giant tires and technological innovation, the width of the cord layer is continuously increasing while the angle is decreasing.

[0003] Due to the small angle, long oblique side length of the belt layer, and increased belt layer width, small-angle giant tire joints typically employ two methods. One method uses the joint as a power source to drive a feeding conveyor belt and an unloading conveyor belt, primarily composed of strip-shaped telescopic belts, to complete the splicing action. This method limits the joint's minimum rotation angle to 15°, and when the angle is less than 20°, the outermost two strip-shaped belt frames will skew, leading to inaccurate feeding accuracy. The second method uses an all-steel small-angle cutting machine joint. The inertial force of the feeding conveyor belt drives the fabric to the joint splicing position to complete the splicing action. This method is only suitable for splicing materials with a cutting width less than 400mm and a cutting angle greater than 15°. When the cutting width is greater than 400mm and the cutting angle is less than 15°, the inertial force of the feeding conveyor belt alone cannot deliver the fabric to the joint splicing position, failing to meet the requirements of giant tire manufacturing processes.

[0004] To address the specific requirements of small-angle giant tires regarding the angle and width of the belt layer, the steel cord fabric used in them has a smaller angle (usually less than 15°) and a wider cutting width (usually greater than 700mm) than the steel cord fabric used in traditional tires. The two existing splicing methods cannot meet the process requirements of small-angle giant tires for angle and width.

[0005] Therefore, existing jointing equipment cannot meet the production requirements of small-angle rubber joints for giant tires. Summary of the Invention

[0006] The main objective of this invention is to provide an automatic rubber jointing device to solve the problem that existing jointing equipment cannot meet the production requirements of small-angle rubber joints for giant tires.

[0007] To achieve the above objectives, according to one aspect of the present invention, an automatic adhesive splicing device is provided, comprising: a first conveying assembly; a second conveying assembly, the first and second conveying assemblies being sequentially linked along a length direction, the first and second conveying assemblies having the same conveying direction, and the first conveying assembly being located downstream of the second conveying assembly in the conveying direction of the first and second conveying assemblies; a splicing assembly, the splicing assembly being movably disposed above one end of the first conveying assembly near the second conveying assembly, and the angle between the splicing direction of the splicing assembly and the conveying direction of the first conveying assembly being adjustable; and a lifting assembly, at least a portion of the lifting assembly being movably disposed on the side of the first conveying assembly facing the splicing assembly, and the lifting assembly being movable in the height direction in a direction approaching or away from the splicing assembly to lift or lower the adhesive on the first conveying assembly.

[0008] Furthermore, the connector assembly has a first included angle position and a second included angle position relative to the first conveying assembly. When the angle of the connector assembly relative to the first conveying assembly is adjusted, the connector assembly switches between the first included angle position and the second included angle position. When the connector assembly is in the first included angle position, the angle between the connector direction of the connector assembly and the conveying direction of the first conveying assembly is smaller than the angle between the connector direction of the connector assembly and the conveying direction of the first conveying assembly when the connector assembly is in the second included angle position.

[0009] Furthermore, the lifting assembly includes a first lifting part and a second lifting part. The first lifting part is movably disposed in a first region of the first conveying assembly, and the second lifting part is disposed in a second region of the first conveying assembly. The first region is the projection area of ​​the connector assembly on the first conveying assembly when the connector assembly is angled relative to the first conveying assembly, and the second region is located in the region of the first region away from the second conveying assembly.

[0010] Furthermore, when the connector assembly is in the set position, the connector assembly divides the first area into a lifting area and a stationary area. The lifting area is farther away from the second conveying assembly than the stationary area. The portion of the first lifting part located in the lifting area lifts or lowers the rubber material.

[0011] Furthermore, both the first lifting section and the second lifting section include multiple lifting members and multiple driving members. The driving members are disposed on the first conveying assembly, and the driving members are drivenly connected to the lifting members and drive the lifting members to move in a direction close to or away from the joint assembly.

[0012] Furthermore, the number of lifting members and driving members in the first lifting section are equal and correspond one-to-one; and / or each driving member of the second lifting section is driven connected to at least one different lifting member.

[0013] Furthermore, the multiple lifting components of the second lifting section are divided into multiple groups, and the multiple groups of lifting components are spaced apart along the length direction of the first conveying assembly. The lifting components in the same group are driven and connected to the same driving component.

[0014] Furthermore, the first conveying assembly includes: a conveying frame, with the driving members of the first lifting part and the second lifting part respectively disposed on the conveying frame; multiple conveyor belts, which are spaced apart along the width direction of the conveying frame, and there is a lifting gap between two adjacent conveyor belts, and the lifting members of the first lifting part and the second lifting part can extend out through the lifting gap.

[0015] Furthermore, the connector assembly includes: a body portion, at least a portion of which is movably disposed above the first conveying assembly, and the angle between the connector direction of the body portion and the conveying direction of the first conveying assembly is adjustable; a drive seat; and a rotating center seat, the two ends of the body portion being connected to the two ends of the drive seat and the rotating center seat respectively, and the body portion being rotatable relative to the drive seat and the rotating center seat.

[0016] Furthermore, the connector assembly also includes: an angle detection element disposed on the drive seat; and / or an encoder disposed on the rotation center seat.

[0017] Applying the technical solution of this invention, the automatic rubber splicing device of this application includes a first conveying component, a second conveying component, a splicing component, and a lifting component. The first conveying component and the second conveying component are sequentially connected along the length direction, and the conveying directions of the first conveying component and the second conveying component are the same. In the conveying directions of the first conveying component and the second conveying component, the first conveying component is located downstream of the second conveying component. The splicing component is movably disposed above one end of the first conveying component near the second conveying component, and the angle between the splicing direction of the splicing component and the conveying direction of the first conveying component is adjustable. At least a portion of the lifting component is movably disposed on the side of the first conveying component facing the splicing component. In the height direction, the lifting component can move in a direction close to or away from the splicing component to lift or lower the rubber on the first conveying component.

[0018] When using the automatic rubber splicing device of this application to splice two pieces of rubber, the two pieces of rubber can be conveyed through the second conveying component. When the first piece of rubber is completely conveyed onto the first conveying component, the lifting component can lift the first piece of rubber completely. When the second piece of rubber moves to the splicing position corresponding to the splicing component, the lifting component can lower the first piece of rubber and complete the splicing operation of the two pieces of rubber through the splicing component. In this application, since the splicing angle of the splicing component can be adjusted, splicing operations of rubber at different angles can be achieved. Furthermore, since the first piece of rubber can be lifted by the lifting component before splicing, the problem of inaccurate feeding accuracy caused by frame tilting when the splicing angle is less than 20° in the prior art can be effectively avoided. At the same time, by having the first and second conveying components simultaneously drive the movement of the two pieces of rubber, the technical problem in the prior art that the inertial force of the feeding conveyor belt alone cannot deliver the fabric to the splicing position, which does not meet the requirements of the giant tire process can be effectively solved. Therefore, the automatic rubber jointing device in this application effectively solves the problem that the existing jointing equipment cannot meet the production needs of small-angle rubber joints for giant tires.

Detailed Implementation

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0030] To address the problem that existing splicing equipment cannot meet the production requirements of small-angle rubber joints for giant tires, this application provides an automatic rubber jointing device.

[0031] like Figures 1 to 5 As shown, the automatic rubber splicing device of this application includes a first conveying assembly 10, a second conveying assembly 20, a splicing assembly 30, and a lifting assembly 40. The first conveying assembly 10 and the second conveying assembly 20 are sequentially connected along the length direction, and the conveying directions of the first conveying assembly 10 and the second conveying assembly 20 are the same. In the conveying direction 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 splicing assembly 30 is movably disposed above one end of the first conveying assembly 10 near the second conveying assembly 20, and the angle between the splicing direction of the splicing assembly 30 and the conveying direction of the first conveying assembly 10 is adjustable. At least a portion of the lifting assembly 40 is movably disposed on the side of the first conveying assembly 10 facing the splicing assembly 30. In the height direction, the lifting assembly 40 can move in a direction close to or away from the splicing assembly 30 to lift or lower the rubber on the first conveying assembly 10.

[0032] When using the automatic rubber splicing device of this application to splice two pieces of rubber, the two pieces of rubber can be conveyed through the second conveying component 20. When the first piece of rubber is completely conveyed onto the first conveying component 10, the lifting component 40 can lift the first piece of rubber completely. When the second piece of rubber moves to the splicing position corresponding to the splicing component 30, the lifting component 40 can put the first piece of rubber down and complete the splicing operation of the two pieces of rubber through the splicing component 30. In this application, since the splicing angle of the splicing component 30 can be adjusted, splicing operations of rubber at different angles can be realized. Furthermore, since the first piece of rubber can be lifted by the lifting component 40 before splicing, the problem of inaccurate feeding accuracy caused by the tilting of the frame when the splicing angle is less than 20° in the prior art can be effectively avoided. At the same time, the simultaneous movement of the two pieces of rubber by the first conveying component 10 and the second conveying component 20 can effectively solve the technical problem in the prior art that the inertial force of the feeding conveyor belt alone cannot deliver the fabric to the splicing position, which does not meet the requirements of the giant tire process. Therefore, the automatic rubber jointing device in this application effectively solves the problem that the existing jointing equipment cannot meet the production needs of small-angle rubber joints for giant tires.

[0033] In other words, in this application, the first conveying component 10 is equivalent to the joint conveyor belt in the prior art, and the second conveying component 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°. Furthermore, the rubber compound used in the production of 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 Regarding the arrangement of the first conveying component 10 and the second conveying component 20, the conveying direction of both the first conveying component 10 and the second conveying component 20 is from right to left, and the first conveying component 10 is located to the left of the second conveying component 20.

[0036] It should be noted that when joining the rubber materials, the joining is actually performed on the ends of the two rubber materials that are close to each other, that is, joining the tail of the rubber material downstream of the first conveying component 10 and the head of the rubber material upstream. Furthermore, in this embodiment, the lifting component 40 only lifts or lowers the rubber material located downstream of the first conveying component 10, and does not lift or lower the other rubber material.

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

[0038] exist Figure 3 In the embodiment shown, the two lines marked A in the figure represent the first included angle position and the second included angle position.

[0039] In one specific embodiment of this application, the lifting component 40 includes a first lifting part 41 and a second lifting part 42. The first lifting part 41 is movably disposed in a first region 14 of the first conveying component 10, and the second lifting part 42 is disposed in a second region 15 of the first conveying component 10. The first region 14 is the projection area of ​​the joint component 30 on the first conveying component 10 when the joint component 30 is angled relative to the first conveying component 10, or in other words, the joint component 30 in this application is angled within the first region 14. The second region 15 is located in the region of the first region 14 away from the second conveying component 20. It should be noted that since the automatic rubber jointing device in this application is mainly designed to meet the production process requirements of giant tires, the width of the rubber is generally greater than 700mm, which results in a heavier transported rubber. Therefore, if the joint angle between the two pieces of rubber is small, when the first piece of rubber located in front moves onto the first conveying component 10 in the conveying direction of the first conveying component 10 and the second conveying component 20, it may cause uneven force on the first conveying component 10. Therefore, by setting up the lifting component 40, the adhesive material located on the first conveying component 10 can be supported to a certain extent, thereby solving the problem in the prior art where the frame body will tilt, resulting in inaccurate feeding accuracy.

[0040] Furthermore, it should be noted that in this application, the first region 14 is determined based on the angle adjustment range of the connector assembly 30, rather than the adjustment range of the connector assembly 30 is limited based on the first region 14. That is, when the angle adjustment range of the connector assembly 30 is different, the area of ​​the first region 14 of the first conveying assembly 10 is different.

[0041] Specifically, when the connector assembly 30 is in the set position, it divides the first region 14 into a lifting region and a stationary region. The lifting region is farther from the second conveying assembly 20 than the stationary region. The portion of the first lifting part 41 located in the lifting region lifts or lowers the adhesive material. Alternatively, for two pieces of adhesive material that need to be joined, the area where the tail of the preceding piece of adhesive material is located is the lifting region, while the area where the tail of the following piece of adhesive material is located is the stationary region. Therefore, in this application, the lifting assembly 40 only lifts or lowers the first piece of adhesive material located on the first conveying assembly 10.

[0042] In the above embodiments, by providing the first lifting part 41 and the second lifting part 42, different positions of the first piece of rubber can be lifted respectively. Furthermore, as can be seen from the above arrangement, in this application, the first lifting part 41 mainly lifts or lowers the tail of the first piece of rubber. Therefore, when the angle of the joint changes, the area of ​​the tail of the first piece of rubber will change, or in other words, the area of ​​the lifting area and the area of ​​the stationary area will change. Therefore, it is necessary to increase or decrease the moving portion of the first lifting part 41.

[0043] In a preferred embodiment of this application, the first lifting part 41 can be signal-connected to the connector assembly 30, thereby ensuring that when the connector angle of the connector assembly 30 changes, the lifting portion of the first lifting part 41 can be adjusted accordingly. Of course, in this application, the control of the first lifting part 41 and the second lifting part 42 can also be manually controlled and adjusted by an operator.

[0044] Optionally, such as Figure 4 and Figure 5 As shown, both the first lifting section 41 and the second lifting section 42 include multiple lifting members 43 and multiple driving members 44. The driving members 44 are disposed on the first conveying assembly 10, and are drivenly connected to the lifting members 43, driving the lifting members 43 to move in a direction closer to or away from the joint assembly 30. In this application, the first lifting section 41 and the second lifting section 42 drive the lifting members 43 to move via the driving members 44, thereby driving the rubber material to move via the lifting members 43, thus realizing the lifting or lowering of the rubber material. Further optionally, the lifting members 43 are made of carbon steel. Furthermore, in this application, the driving member 44 can be a cylinder. Of course, in addition to using a cylinder, other components can be used instead of the driving member 44.

[0045] In one specific embodiment of this application, such as Figure 4 and Figure 5As shown, the number of lifting members 43 and driving members 44 in the first lifting part 41 are equal and correspond one-to-one; and each driving member 44 of the second lifting part 42 is driven connected to at least one different lifting member 43. In this application, since the moving part of the first lifting part 41 needs to be adjusted when the joint angle of the two pieces of rubber changes, that is, the number of moving lifting members 43 of the first lifting part 41 needs to be adjusted, the accurate adjustment of the first lifting part 41 can be achieved by setting the number of lifting members 43 and driving members 44 of the first lifting part 41 to be equal and correspond one-to-one, thereby ensuring the lifting effect of the rubber, or ensuring that the moving lifting part can contact the rubber so that the first lifting part 41 will not lift the second piece of rubber located upstream, thereby ensuring the joint effect of the head and tail of the two pieces of rubber. Preferably, the multiple lifting members 43 of the second lifting section 42 are divided into multiple groups, and the multiple groups of lifting members 43 are spaced apart along the length direction of the first conveying assembly 10. The lifting members 43 in the same group are driven and connected to the same driving member 44. In this embodiment, for the second lifting section 42, when the joint angle of the two pieces of rubber changes, since it is not necessary to adjust the number of moving lifting members 43 of the second lifting section 42, the multiple lifting members 43 of the second lifting section 42 are divided into multiple groups. The multiple groups of lifting members 43 are spaced apart along the length direction of the first conveying assembly 10. The lifting members 43 in the same group are driven and 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 does not tilt after being lifted by the second lifting section 42, thus ensuring the joint effect of the two pieces of rubber, and that the rubber does not tilt during the conveying process.

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

[0047] In one specific embodiment of this application, the first conveying assembly 10 includes a conveying frame 11 and conveyor belts 12. The driving members 44 of the first lifting section 41 and the second lifting section 42 are respectively disposed on the conveying frame 11. Multiple conveyor belts 12 are spaced apart along the width direction of the conveying frame 11, and there is a lifting gap between adjacent conveyor belts 12. The lifting members 43 of the first lifting section 41 and the second lifting section 42 can extend out through the lifting gap. That is, in this embodiment, when the first conveying assembly 10 conveys the adhesive material, the multiple conveyor belts 12 simultaneously move relative to the conveying frame 11 in the conveying direction of the first conveying assembly 10, and the first conveying assembly 10 conveys the adhesive material through the conveyor belts 12. Meanwhile, since the rubber material needs to be lifted by the first lifting part 41 and the second lifting part 42, setting a lifting gap between two adjacent conveyor belts 12 can effectively ensure that the rubber material can be lifted by the first lifting part 41 and the second lifting part 42, while also effectively preventing the first lifting part 41 and the second lifting part 42 from contacting the conveyor belt 12 during movement, or in other words, effectively preventing the conveyor belt 12 from obstructing the movement of the first lifting part 41 and the second lifting part 42. It should be noted that in this application, the structures of the first conveying assembly 10 and the second conveying assembly 20 can be the same, or the first conveying assembly 10 and the second conveying assembly 20 can be combined into one.

[0048] In the above embodiment, a pad 13 can be added above the conveyor frame 11, and the pad 13 is located between the conveyor frame 11 and the conveyor belt 12. Simultaneously, the first lifting component 40 can be placed on the pad 13, and the second lifting component 40 can be placed on the conveyor frame 11. This arrangement achieves two different technical effects. Firstly, while ensuring that the first conveyor component 10 and the second conveyor component 20 are lifted to the same height, the energy consumed by the first lifting component 40 is reduced because the pad 13 has already increased its height. Secondly, while ensuring that the first conveyor component 10 and the second conveyor component 20 are lifted to the same height, the pad 13 has already increased its height, allowing the first component to lift the tail of the adhesive material higher than the rest of the adhesive material, thus ensuring easier splicing of the two pieces of adhesive material. Of course, in actual use, the heights of the first and second lifting components 40 after lifting can be adjusted according to the actual production process requirements.

[0049] Specifically, the connector assembly 30 includes a body portion 31, a drive seat 32, and a rotation center seat 33. At least a portion of the body portion 31 is movably disposed above the first conveying assembly 10, and the angle between the connector direction of the body portion 31 and the conveying direction of the first conveying assembly 10 is adjustable. Both ends of the body portion 31 are respectively connected to the drive seat 32 and the rotation center seat 33, and the body portion 31 is rotatable relative to the drive seat 32 and the rotation center seat 33. This arrangement allows the body portion 31 to be driven by the drive seat 32, enabling the body portion 31 to move along the drive seat 32 and rotate relative to the rotation center seat 33. Preferably, the body portion 31 can be connected to the rotation center seat 33 via a linkage mechanism or other structure.

[0050] In an optional embodiment of this application, the drive seat 32 and the rotation center seat 33 are respectively disposed at both ends of the length direction of the first conveying assembly 10 and approximately along the diagonal of the first conveying assembly 10. Furthermore, the rotation center seat 33 may be disposed below the first conveying assembly 10. Of course, the actual positions of the drive seat 32 and the rotation center seat 33 in this application can also be adjusted according to specific production conditions, as long as it ensures that the main body 31 can smoothly join the two pieces of adhesive material.

[0051] Optionally, the joint assembly 30 also includes an angle detection element 34 and an encoder 35. The angle detection element 34 is mounted on the drive base 32, and the encoder 35 is mounted on the rotation center base 33. In this application, the encoder 35 is mainly used to control the angle rotation of the main body 31, while the angle detection element 34 is provided to ensure that the main body 31 does not exceed the limit angle during angle adjustment, thereby ensuring the stable operation of the automatic rubber jointing device.

[0052] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: When using the automatic glue splicing device of this application to splice two pieces of glue, the two pieces of glue can be conveyed by the second conveying component 20. When the first piece of glue is completely conveyed onto the first conveying component 10, the lifting component 40 can lift the first piece of glue completely. When the second piece of glue moves to the splicing position corresponding to the splicing component 30, the lifting component 40 can put the first piece of glue down and complete the splicing operation of the two pieces of glue through the splicing component 30. In this application, since the splicing angle of the splicing component 30 can be adjusted, splicing operations of glue at different angles can be realized. Furthermore, since the first piece of glue can be lifted by the lifting component 40 before splicing, the problem of inaccurate feeding accuracy caused by the tilting of the frame when the splicing angle is less than 20° in the prior art can be effectively avoided. Meanwhile, by simultaneously driving the movement of the two rubber materials through the first conveying component 10 and the second conveying component 20, the technical problem in the prior art that the inertial force of the feeding conveyor belt alone cannot deliver the fabric to the joint splicing position, thus failing to meet the requirements of the giant tire process, can be effectively solved. Therefore, the automatic rubber material splicing device in this application effectively solves the problem that the splicing equipment in the prior art cannot meet the production needs of small-angle rubber material splices for giant tires.

[0053] The key feature of this invention is that the feeding, splicing, and unloading actions can be performed on the same strip conveyor belt 12, and the lifting component 40 is used to automatically splice materials with an angle of less than 15°. When the splicing component 30 rotates around its center to change its angle, the lifting component 40 switches to the corresponding lifting section according to the splicing angle. When material arrives, the tail of the material is raised to await feeding, depending on its angle. After the material is in place, the lifting component 40 lowers, the automatic splicing device performs the splicing, and the conveyor belt unloads the material after splicing. Changing the process angle only requires the splicing component 30 to rotate, improving the mechanical repeatability and positioning accuracy, meeting the manufacturing process requirements of the giant tire belt layer. The feeding, splicing, and unloading actions are performed on the same belt, solving the problem that wide materials cannot be fed to the splicing support position, greatly improving splicing efficiency; at the same time, it improves the automation level of the giant tire small-angle cutting machine.
