Description

Technical Field

[0001] This invention relates to the field of tire manufacturing, and specifically to a belt layer transmission ring motion stroke control device and its working method. Background Technology

[0002] In tire manufacturing, especially for heavy-duty radial truck tires, the belt layer transfer ring is a crucial component of the tire forming machine. The belt layer transfer ring transports the belt layer tread assembly to the forming drum and also transports the formed tire carcass to the tire unloading station. The belt layer transfer ring includes a ring seat, which supports the ring body. Multiple sets of clamping claws are mounted on the ring body. These clamping claws are driven by a locking cylinder and can extend and retract radially. The stroke of the locking cylinder is controlled according to the different diameters of the tire crown.

[0003] On the existing belt layer transfer ring, all clamping claws are evenly distributed within the inner ring. A cylinder drives the clamping claws to extend or retract radially. All clamping claws are linked by guide rods and hinged to the cylinder's ejector end via connecting rods. To control the stroke of the cylinder's ejector end, a set screw is fixed above it. A proximity sensor is mounted below the set screw via an L-shaped connector. This proximity sensor detects whether the cylinder's ejector end is in position, and its position is adjusted by adjusting the set screw. When switching tire production specifications, especially when the circumferential circumference of the belt layer tread assembly differs significantly between the two specifications, the set screw needs to be adjusted to change the position of the proximity sensor, moving it to a position capable of detecting the cylinder's ejector end and activating the control switch. However, when frequently changing tire production specifications, the length of the set screw needs to be frequently adjusted. The set screw is located inside the ring seat, which is inconvenient to operate and results in low adjustment efficiency. Furthermore, because its location is relatively hidden, if the length of the set screw is forgotten or is not adjusted properly, the cylinder ejector end may not extend fully during the extension process. This can cause the clamping claws to be unable to fully fit the outer surface of the belt layer tread assembly, resulting in the belt layer tread assembly sagging and deforming. If the cylinder ejector end extends too far, it can cause the clamping claws to excessively constrain the deformation of the belt layer tread assembly, leading to dimensional defects in the belt layer tread. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a belt layer transfer ring motion stroke control device and working method. Through the sliding engagement of the slot and the ring seat, the position of the proximity sensor can be adjusted directly by sliding the fixed seat on the ring seat. Unlike in the past, there is no need to operate the set screw located in a hidden position inside the ring seat, making the adjustment process more intuitive and convenient. This reduces the probability of forgetting to adjust or adjusting improperly, and reduces problems such as belt layer tread assembly sagging, deformation, and dimensional defects caused by the cylinder ejector end not extending in place or extending too far.

[0005] The first objective of this invention is to provide a belt layer transfer ring motion stroke control device, which adopts the following solution: The device includes a proximity sensor and a mounting base mounted on the belt layer transfer ring seat. The mounting base includes a first clamping plate and a second clamping plate, with a groove formed between them. The first and second clamping plates are respectively provided with fixing holes. The proximity sensor is installed in the fixing holes, with its detection end facing the running path of the belt layer transfer ring drive cylinder ejection end to measure the position of the ejection end and send it to the controller. The groove is used to engage with the ring seat to form a sliding fit. A locking element is fitted on the mounting base, which connects the first and second clamping plates and maintains the distance between them, thus maintaining the position of the mounting base and the ring seat.

[0006] Furthermore, grooves are formed on both sides of the axis of the fixing hole, and they slide in cooperation with the ring seat respectively.

[0007] Furthermore, the first clamping plate and the second clamping plate are respectively provided with threaded holes, and the locking element is engaged with the threaded holes through external threads.

[0008] Furthermore, the locking component is a locking bolt, the threaded section of which sequentially engages with the first clamping plate and the second clamping plate, and a rotating handle is provided at the end of the locking bolt away from the second clamping plate.

[0009] Furthermore, a protrusion is provided at one end of the first clamping plate along the axial direction of the fixing hole, and the protrusion is located between the first clamping plate and the second clamping plate.

[0010] Furthermore, the second clamping plate has an extension on the side of the fixing hole axially away from the first clamping plate. The extension protrudes from the second clamping plate, and the fixing hole passes through the first clamping plate, the protrusion, the second clamping plate, and the extension in sequence.

[0011] The second objective of this invention is to provide a belt layer transfer ring motion stroke control device, which employs the following solution: The device includes a proximity sensor and a mounting base installed on the belt layer transfer ring seat. The mounting base has a slot and a fixing hole. The proximity sensor is installed in the fixing hole. The detection end of the proximity sensor faces the running path of the push-out end of the belt layer transfer ring drive cylinder to measure the position of the push-out end and send it to the controller. The slot is used to engage with the ring seat to form a sliding fit. The mounting base is fitted with a locking element. One end of the locking element is located outside the slot, and the other end extends into the slot to abut against and clamp the ring seat, maintaining the position of the mounting base and the ring seat.

[0012] Furthermore, the locking component is a locking bolt, the threaded section of which engages with a pre-set threaded hole on the fixed seat, and a rotating handle is provided at the end of the locking bolt away from the slot.

[0013] A third objective of the present invention is to provide a method for operating the belt layer transfer ring motion stroke control device as described in the first objective, comprising: The position of the end of the movement path of the clamping claw is determined based on the molding parameters of the belt layer platform assembly, thereby determining the position of the end of the movement path of the cylinder ejection end. Loosen the locking parts so that the fixed seat can move along the ring seat, which will move the proximity sensor to the position where its detection end can identify the end of the movement path of the cylinder top; Adjust the locking mechanism to constrain the position of the fixed seat, so that the proximity sensor remains in the adjusted position to identify the cylinder top end.

[0014] Furthermore, the cylinder clamping pressure is adjusted so that the pressure transmitted to the belt layer platform assembly under the maximum cylinder clamping pressure is less than the crushing pressure of the belt layer tread assembly.

[0015] Compared with the prior art, the advantages and positive effects of this invention are: To address the issue of varying travel requirements for the belt layer drive ring in different tire sizes, which are often inconvenient to achieve, a new method has been developed. This method utilizes a sliding engagement between the slot and the ring seat to directly adjust the position of the proximity sensor by sliding the fixed seat on the ring seat. This eliminates the need to operate the hidden set screws located inside the ring seat, making the adjustment process more intuitive and convenient. It reduces the probability of forgetting to adjust or adjusting incorrectly, and minimizes problems such as belt layer tread assembly sagging, deformation, and dimensional defects caused by insufficient or excessive extension of the cylinder tip. The method accurately detects the position of the cylinder tip, ensuring the gripper moves precisely according to tire crown diameters. It guarantees a good fit between the gripper and the outer surface of the belt layer tread assembly, avoiding over-constraint or poor fit. This ensures the dimensional accuracy of the belt layer tread, improves tire product quality, increases adjustment efficiency, and adapts to frequent changes in tire production specifications.

[0016] The dual-slot design allows for smoother sliding of the mounting base on the ring seat and more precise positioning. When adjusting the proximity sensor position, the operator can directly push the mounting base along the surface of the ring seat without complicated angle adjustments, further simplifying the operation process when switching specifications.

[0017] The single-slot structure simplifies the fit between the fixed seat and the ring seat, reduces machining accuracy requirements, and decreases sliding friction resistance, making the sliding adjustment of the fixed seat on the ring seat easier. The clamping locking mechanism allows for precise adjustment of the friction between the fixed seat and the ring seat by controlling the screw insertion depth. When fine-tuning the proximity sensor position is required, it is not necessary to completely loosen the locking bolt; simply loosening it slightly is sufficient to push the fixed seat, avoiding positional shifts caused by complete disassembly, thus achieving a combination of "fine-tuning" and "quick fixing."

[0023] Example 1 In a typical embodiment of the present invention, such as Figures 1-2 As shown, a belt layer transfer ring motion stroke control device is presented.

[0024] When switching tire production specifications, especially when the circumferential circumference of the belt layer tread assembly differs significantly between the two tire specifications, the length of the concealed set screw 11 located inside the ring seat 2 needs frequent adjustment to change the position of the proximity sensor 6, enabling the proximity sensor 6 to detect whether the cylinder tip is in position. Figure 1 As shown, the position of the L-shaped connector 10 is changed by adjusting the set screw 11, thereby driving the proximity sensor 6 to adjust its position. However, this operation is inconvenient, resulting in low adjustment efficiency. Furthermore, it is easy to forget to adjust or adjust improperly, causing the cylinder ejector end to not extend fully, making it difficult for the clamping claw to completely fit the outer surface of the belt layer tread assembly, leading to its sagging and deformation. Alternatively, the cylinder ejector end may overextend, causing the clamping claw to excessively constrain the belt layer tread assembly, resulting in deformation and dimensional defects in the belt layer tread. Based on this, this embodiment provides a belt layer transfer ring travel control device. A fixed base 7 supports the proximity sensor 6, and the fixed base 7 is slidably installed on the belt layer transfer ring 1 ring seat 2. The position of the proximity sensor 6 can be quickly adjusted by sliding, allowing the sliding sensor to quickly reach the required recognition position, improving the adaptability and adjustment efficiency of the belt layer transfer ring 1 to different tire specifications.

[0025] like Figure 1As shown, the belt layer transfer ring motion control device includes a fixed base 7, which consists of a first clamping plate 3 and a second clamping plate 4, with a groove 12 formed between them. The groove allows the ring seat 2 to be engaged to form a sliding fit, facilitating the sliding adjustment of the fixed base 7 on the ring seat 2. The first clamping plate 3 and the second clamping plate 4 are respectively provided with fixing holes. A proximity sensor 6 engages with both the first clamping plate 3 and the second clamping plate 4, and the detection end 8 of the proximity sensor 6 faces the running path of the belt layer transfer ring 1 drive cylinder ejection end, thus measuring the ejection end position and sending it to the controller.

[0026] The fixing seat 7 is fitted with a locking member 5, which connects the first clamping plate 3 and the second clamping plate 4 and maintains the distance between them, thereby maintaining the position of the fixing seat 7 and the ring seat 2 and ensuring that the proximity sensor 6 will not move arbitrarily after its position is fixed.

[0027] The position of the proximity sensor 6 can be adjusted directly by sliding the fixed seat 7 on the ring seat 2 through the sliding engagement of the slot 12 and the ring seat 2. This eliminates the need to operate the set screw 11 located in a concealed position inside the ring seat 2, making operation more convenient and significantly improving adjustment efficiency. The belt layer transfer ring motion stroke control device makes the adjustment process more intuitive and convenient, reducing the probability of forgetting to adjust or improper adjustment. It also reduces problems such as sagging deformation and dimensional defects of the belt layer tread assembly caused by insufficient or excessive extension of the cylinder tip. The belt layer transfer ring motion stroke control device can accurately detect the position of the cylinder tip, ensuring accurate movement of the clamping claws according to different tire crown diameters. This ensures good contact between the clamping claws and the outer surface of the belt layer tread assembly, avoiding excessive constraint or poor contact, thereby guaranteeing the dimensional accuracy of the belt layer tread and improving tire product quality.

[0028] Both sides of the fixing hole axis form grooves 12, forming a double-rail sliding fit with the ring seat 2. Compared with the single groove 12 structure, this effectively balances the force on the fixing seat 7 during sliding, avoiding tilting or shaking caused by unilateral force, ensuring that the detection end 8 of the proximity sensor 6 is always aligned with the running path of the cylinder top, and improving detection accuracy. The double groove 12 design makes the sliding of the fixing seat 7 on the ring seat 2 smoother and the positioning more precise. When it is necessary to adjust the position of the proximity sensor 6, the operator can directly push the fixing seat 7 along the surface of the ring seat 2 without complicated angle adjustments, further simplifying the operation process when switching specifications.

[0029] The first clamping plate 3 and the second clamping plate 4 are provided with threaded holes. The locking seat 7 and the ring seat 2 are locked together by the engagement of the external thread on the locking bolt with the threaded hole. The operator can disassemble or install the locking component 5 as needed, which facilitates quick fixation after position adjustment and also facilitates disassembly and maintenance in the later stage. The threaded locking method can control the preload by rotating the locking bolt a certain number of times, avoiding the fixed seat 7 from sliding due to insufficient locking force or the clamping plate structure from excessive locking force, thus ensuring the stability of the fixed seat 7 during production.

[0030] The rotary handle design allows operators to manually tighten or loosen locking bolts without the need for additional tools (such as wrenches), significantly reducing operation time, especially in space-constrained areas such as the inner side of the ring seat 2. When frequent tire size changes are required, operators can quickly fix and unlock the mounting seat 7 by rotating the handle, improving production efficiency. The shape and size of the handle can be designed as needed for easy gripping and force application, reducing operator workload and fatigue caused by frequent operation.

[0031] Understandably, corresponding marks can also be pre-set on the ring seat 2. After the fixing seat 7 is adjusted to the position corresponding to the marks, the position of the proximity sensor 6 corresponds exactly to the production of a certain specification of tire, so that the mark position matches the constraint state of the belt layer tread assembly of different specifications of tires. By controlling the fixing seat 7 to match different marks, quick adjustment and switching can be performed.

[0032] The protrusion is located between the first clamping plate 3 and the second clamping plate 4. When the fixed seat 7 is installed on the ring seat 2, the protrusion can be embedded in the corresponding sliding groove of the ring seat 2. The auxiliary slot 12 completes the initial positioning of the fixed seat 7 and prevents the fixed seat 7 from deviating from the detection path of the cylinder top end during the sliding process.

[0033] The protrusion is arranged opposite to the second clamping plate 4, so that the protrusion abuts against the second clamping plate 4. This can form a more uniform clamping force on the ring seat 2 when the locking bolt is tightened, preventing the fixed seat 7 from shifting in the radial or circumferential direction, and ensuring that the detection position of the proximity sensor 6 is always accurate.

[0034] An extension is provided on the side of the fixing hole on the second clamping plate 4 that is axially away from the first clamping plate 3. The extension protrudes from the second clamping plate 4, allowing the fixing hole to pass through the first clamping plate 3, the protrusion, the second clamping plate 4, and the extension, which is equivalent to increasing the installation depth of the proximity sensor 6. When the stroke range of the cylinder tip is large, the extension can accommodate the sensor detection end 8 to extend a longer distance, ensuring that the sensor can cover the full stroke detection requirements of the tip when producing tires of different specifications.

[0035] In addition, the extension can shield the tail wiring or interface of the proximity sensor 6, reducing the impact of dust, oil and other impurities on the sensor during the production process, and improving the reliability and service life of the equipment.

[0036] The design of the double-slot sliding fit, rotary handle operation, and positioning structure (protrusion and extension) avoids abnormal cylinder stroke due to adjustment errors. The threaded locking and double-rail positioning structure can withstand vibration and impact during production, reducing the probability of loosening of the fixed seat 7 and reducing the failure of the clamping jaws due to sensor position misalignment.

[0037] The detachable locking design and extension structure allow the device to be adapted to different tire sizes, and the disassembly steps for sensor maintenance are simplified from 5 steps in the traditional solution to 2 steps, significantly improving maintenance efficiency.

[0038] Example 2 In another typical embodiment of the present invention, such as Figure 3 As shown, a belt layer transfer ring motion stroke control device is presented.

[0039] The difference from Embodiment 1 is that the fixed seat 7 in this embodiment adopts an integrated structure. The belt layer transfer ring movement stroke control device includes a proximity sensor 6 and a fixed seat 7 installed on the belt layer transfer ring 1 ring seat 2. The fixed seat 7 is provided with a slot 12 and a fixing hole. The proximity sensor 6 is installed in the fixing hole. The detection end 8 of the proximity sensor 6 faces the running path of the drive cylinder ejection end of the belt layer transfer ring 1 to measure the position of the ejection end and send it to the controller. The slot 12 is used to engage with the ring seat 2 to form a sliding fit. The fixed seat 7 is fitted with a locking member 5. One end of the locking member 5 is located outside the slot 12, and the other end protrudes into the slot 12 to abut and clamp the ring seat 2, maintaining the position of the fixed seat 7 and the ring seat 2.

[0040] Specifically, the slots 12 on the mounting base 7 are positioned separately from the mounting holes, allowing for more flexible installation of the mounting base 7 on the ring seat 2. This is especially suitable for scenarios where the surface structure of the ring seat 2 is complex or space is limited. When other components (such as air pipes or cables) are present inside the ring seat 2, the separated slots 12 can avoid interference areas, ensuring that the mounting base 7 can be installed in the optimal detection position.

[0041] Compared to the double-slot design in the first objective, the single-slot 12 sliding fit simplifies the fit between the fixed seat 7 and the ring seat 2, reduces the machining accuracy requirements, and decreases sliding friction resistance, making the sliding adjustment of the fixed seat 7 on the ring seat 2 easier. When changing tire specifications, the operator can push the fixed seat 7 with one hand, further improving adjustment efficiency.

[0042] In this embodiment, a single-point clamping fixing method is adopted. One end of the locking bolt is inserted into the slot 12 and abuts against the ring seat 2, while the other end is located outside the slot 12 and operated by rotating the handle. The clamping fixing method is different from the clamping method of clamping the ring seat 2 with double clamps in Embodiment 1. In this method, the axial thrust when the bolt is screwed in causes friction between the inner wall of the slot 12 and the surface of the ring seat 2, thereby maintaining the position of the fixing seat 7.

[0043] The clamping locking mechanism allows for precise adjustment of the friction between the fixed seat 7 and the ring seat 2 by controlling the screw insertion depth of the bolt. When fine-tuning the position of the proximity sensor 6 is required, it is not necessary to completely loosen the locking bolt; simply loosening it slightly is sufficient to push the fixed seat 7, avoiding positional displacement caused by complete disassembly and achieving a combination of fine-tuning and quick fixing.

[0044] A rotating handle is provided at the end of the locking bolt away from the slot 12, so that the operating end is located outside the slot 12, which can avoid interference between the handle and other components inside the ring seat 2. The locking component 5 is a locking bolt, and the threaded section of the locking bolt mates with the pre-set threaded hole on the fixed seat 7. The end of the locking bolt away from the slot 12 is provided with a rotating handle. When the space inside the ring seat 2 is narrow, the rotating handle can be rotated outward, and the operator can complete the locking operation without reaching in with their arm. The engagement between the threaded section and the threaded hole of the fixed seat 7 provides a stable preload force. The rotating handle can be designed with an anti-slip texture to effectively prevent the bolt from loosening due to vibration during production.

[0045] Example 3 In another typical embodiment of the present invention, such as Figures 1-2 As shown, a method for operating a belt layer transfer ring motion stroke control device is given, which utilizes the belt layer transfer ring motion stroke control device as described in Example 1.

[0046] A method for operating a belt layer transfer ring motion stroke control device includes: The position of the end of the movement path of the clamping claw is determined based on the molding parameters of the belt layer platform assembly, thereby determining the position of the end of the movement path of the cylinder ejection end. Loosen the locking element 5 so that the fixed seat 7 can move along the ring seat 2, which will drive the proximity sensor 6 to move to the position at the end of the cylinder top movement path that its detection end 8 can identify. Adjust the locking element 5 to constrain the position of the fixed seat 7, so that the proximity sensor 6 remains in the adjusted position to identify the cylinder top end.

[0047] Adjust the cylinder clamping pressure so that the pressure transmitted to the belt layer platform assembly under the maximum cylinder clamping pressure is less than the crushing pressure of the belt layer tread assembly.

[0048] By calculating the crushing pressure of the belt ply tread assembly using materials mechanics (e.g., when the yield strength of the steel cord ply is 300 MPa, the maximum allowable contact pressure is ≤250 MPa), the cylinder clamping pressure is set to below 80% of the crushing pressure (e.g., 200 MPa). This threshold can be monitored in real time by a pressure sensor, and a warning line is displayed on the HMI interface. When the pressure exceeds the threshold, a shutdown protection is automatically triggered.

[0049] By combining the position signal from proximity sensor 6, the system can achieve pressure-stroke closed-loop control. When the cylinder tip approaches the preset position, the system automatically and slowly increases the pressure from the initial value (e.g., 150MPa) to the set value (200MPa) to avoid deformation of the tread components due to sudden pressure changes.

[0050] The optimal detection distance for proximity sensor 6 can be set to 5-10mm, adjusted according to the sensor model, to avoid damage to the sensor due to excessively close distance or detection failure due to excessively large distance. It is recommended to periodically calibrate the sensor zero point using a standard gauge block; readjustment is necessary if the error exceeds 1mm.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
