Description

Technical Field

[0001] This disclosure relates to the field of tire manufacturing technology, and more specifically, to control methods, devices, electronic equipment, and media for tire tread winding machines. Background Technology

[0002] In tire manufacturing, tread winding is one of the core processes that determines tire quality. The winding thickness, width uniformity, and weight stability of the tread directly affect the tire's driving safety, wear resistance, and service life. This is especially true for large tires such as engineering tires, which have even more stringent requirements for tread winding precision. As the core equipment in this process, the control method of the tread winding machine directly determines the quality of the tread winding.

[0003] Currently, existing tire tread winding machines all employ offline control methods for path planning and control. The core process involves: determining the target thickness, width, and weight of the tread in advance based on the manufacturing process requirements; using offline contouring software for path planning and parameter calculation; and then transmitting the calculated winding path, winding drum speed coefficient, and other fixed parameters to the PLC controller, which then controls the winding machine to perform the winding operation. This offline control method suffers from problems such as inability to handle real-time deviations, poor flexibility, reliance on manual intervention, and difficulties in quality traceability, severely impacting tire tread production quality and efficiency.

[0036] The embodiments of this disclosure are described below with reference to the accompanying drawings. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions of the embodiments of this disclosure.

[0037] The following explains the technical terms and related technologies involved in this disclosure:

[0038] 1. The tire winding machine is the core automated equipment for performing the tire winding process, mainly used in the manufacture of high-performance tires such as giant engineering tires and aircraft tires. It uses precise computer control to stack hot rubber strips layer by layer on the tire carcass, directly "winding" the tire into the desired tread shape.

[0039] A complete tire tread winding machine typically consists of the following key components:

[0040] (1) The winding host is the core of the winding action, including the winding head (including the compaction roller and the exhaust roller) and the rotation and movement device.

[0041] (2) Feeding system, used to provide stable and qualified rubber strips, including extruder, cooling drum, storage device and width measuring device.

[0042] (3) The control system is the "brain" of the equipment, used to control precision and shape, including PLC controller, servo drive, and host computer software (including recipe management).

[0043] 2. The winding drum is the core component of the tire winding machine that carries and fixes the tire carcass (cord roll) to be processed; it can be understood as the "workbench" for the winding operation. The winding drum is not a simple iron cylinder; to facilitate the unloading of the processed tire carcass, it must have radial shrinkage capability. Its typical structural features are as follows:

[0044] The support layer is the central support shaft of the drum, and it contains a screw or piston that drives the contraction mechanism.

[0045] The middle layer, consisting of several radially movable sector-shaped blocks or tiles (commonly 8 or more), is the actuator that enables contraction;

[0046] The working layer, installed on the outside of the sector blocks, is the component that directly contacts the tire carcass. The elastic rubber sleeve ensures a more continuous surface and higher roundness during expansion.

[0047] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0048] See Figure 1 , Figure 1 This is a schematic diagram of the control system of a tire tread winding machine provided in an embodiment of the present disclosure, as shown below. Figure 1 As shown, the control system of the tire tread winding machine includes the following components: tire tread winding machine 11 (also known as tire tread winding machine), winding drum 12, PLC controller 13 (i.e., programmable logic controller, or PLC for short)), vision sensor 14, winding algorithm module 15, winding software 16, and vision software 17.

[0049] The execution entities corresponding to the winding algorithm module 15, winding software 16, and vision software 17 can be servers or terminal devices. The server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server or server cluster providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. The network used by the control system of the aforementioned tire tread winding machine can include, but is not limited to, wired networks and wireless networks. The wired network includes local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs). The wireless network includes Bluetooth, Wi-Fi, and other networks that enable wireless communication. The terminal device can be a smartphone (such as an Android phone, an iOS phone, etc.), a tablet computer, a laptop computer, a digital broadcast receiver, a MID (Mobile Internet Device), a PDA (Personal Digital Assistant), a desktop computer, an in-vehicle terminal (such as an in-vehicle navigation terminal), a smart speaker, a smartwatch, etc. The terminal device and the server can be directly or indirectly connected through wired or wireless communication methods, but are not limited to these. The specific requirements can be determined based on the actual application scenario, and are not limited here.

[0050] The connection relationships of the above components are as follows:

[0051] 1. Visual sensor 14 (i.e., camera): such as Figure 2 and Figure 3 As shown, the vision sensor 14 is fixedly installed at the corresponding position on the winding drum 12 of the tire winding machine 11, and is connected to the vision software 17 for real-time acquisition of image data on the winding drum 12 during the tire winding process. Figure 2Left view of the camera and winding drum mounting structure. Figure 3 A top view of the camera and winding drum mounting structure.

[0052] Among them, the vision sensor 14 can be a three-dimensional camera (i.e., a 3D camera). A three-dimensional camera is a device that can capture three-dimensional images, also known as a depth camera. It acquires the depth information of objects and generates three-dimensional coordinate data through technologies such as structured light, binocular vision, or time of flight (TOF).

[0053] The vision sensor 14 in this embodiment is mainly used to acquire actual data on the tread wrapping of the target tire.

[0054] 2. Vision software 17: Connected to vision sensor 14, winding software 16 and PLC controller 13 via signal transmission. It receives image data (i.e. actual tread winding data) collected by vision sensor 14 through PLC control signals sent by PLC controller 13, preprocesses and extracts the actual tread winding data for each turn, and sends the extracted actual tread winding data for each turn to winding software 16.

[0055] 3. Winding software 16: As a data interaction hub, it establishes signal connections with vision software 17, winding algorithm module 15, and PLC controller 13. It is used to receive the actual tread winding data sent by vision software 17 and transmit it to winding algorithm module 15. At the same time, it receives the output results of winding algorithm module 15, i.e., adjustment instructions (corresponding to winding parameter adjustment instructions), parses them, and sends them to PLC controller 13.

[0056] 4. Winding Algorithm Module 15: It is pre-set with standard tread winding parameters (corresponding to the target thickness, target width, target weight, winding spacing, winding speed, etc. required by the process), and is connected to the winding software 16 by signal. It is used to receive input parameters, namely the real-time data of tread winding (corresponding to the actual data of tread winding), and to generate deviation calculation and adjustment instructions (corresponding to the winding parameter adjustment instructions).

[0057] 5. PLC controller 13: It is connected to the vision software 17, winding software 16, tire winding machine 11, and winding drum 12. It is used to receive control signals, i.e. adjustment instructions (corresponding to winding parameter adjustment instructions) issued by the winding software 16, and control the vision software 17, tire winding machine 11 and winding drum 12 to perform corresponding actions.

[0058] The control flow of this embodiment is sequentially connected in a closed loop to achieve real-time adjustment of the tread winding, such as... Figure 4 As shown, the specific steps are as follows:

[0059] Step S401, Real-time Visual Data Acquisition:

[0060] A 3D camera is fixedly installed at the corresponding position of the winding drum 12 of the tire winding machine 11 as a vision sensor 14 to ensure that the acquisition field of the vision sensor 14 covers the entire tire winding area of ​​the winding drum 12, and the vision sensor 14 establishes a stable signal connection with the vision software 17.

[0061] The PLC controller 13 sends control command 1 to the tread winding machine 11 and the winding drum 12, and simultaneously sends control command 2 to the vision software 17. The control command 1 received by the tread winding machine 11 and the winding drum 12 is a start winding command. The tread winding machine 11 and the winding drum 12 will start to perform tread winding on the target tire based on the received start winding command.

[0062] Meanwhile, the control command 2 received by the vision software 17 is an image acquisition command. The vision software can automatically trigger the vision sensor 14 to acquire images based on the received image acquisition command, and capture the actual data of tire tread winding on the winding drum 12 in real time, mainly including the tread thickness and tread width of the target tire (corresponding to the current thickness value and current width value of the target tire in the text), and send the acquired actual data of tire tread winding to the winding software 16 in real time.

[0063] Among them, the actual data of tread winding is the data corresponding to each turn of the tread winding machine, and it is the data obtained when the current turn is completed.

[0064] Step S402: Real-time interactive data transmission.

[0065] The winding software 16 acts as a data interaction hub, receiving real-time tread data (i.e., actual tread winding data) from the vision software 17 for each tread rotation. First, it verifies and filters the acquired actual tread winding data, removing abnormal data caused by image blurring, equipment interference, etc., and retaining only valid real-time data. Then, it outputs the valid real-time data as input parameters to the winding algorithm module 15 for algorithm calculation. Simultaneously, the winding software 16 receives the tread winding parameters calculated by the winding algorithm module 15 in real-time, preparing for subsequent parameter distribution.

[0066] Step S403, Real-time algorithm calculation of winding parameters:

[0067] The winding algorithm module 15 has preset standard parameters for tread winding corresponding to the tire specifications (set according to process requirements, including threshold ranges such as target thickness and target weight). After receiving the effective real-time tread data transmitted by the winding software, it calculates the actual weight based on the actual data of each tread turn (i.e., actual thickness and actual width). It then compares and analyzes the actual thickness and actual weight with the preset standard parameters in real time to accurately calculate the deviation values ​​of each parameter (such as thickness deviation, weight deviation, etc.). Based on the calculated deviation values, the tread winding parameters are obtained. The winding algorithm module 15 generates corresponding tread winding parameter adjustment instructions (hereinafter referred to as adjustment instructions) in real time according to the tread winding parameters. The adjustment instructions include, but are not limited to, winding spacing adjustment and winding position correction. In practical applications, the adjustment instructions may also include winding speed adjustment (such as instructions to keep the winding speed constant) and feeding speed adjustment (such as instructions to keep the feeding speed constant) to ensure that the adjusted data can quickly approach the standard parameters. Subsequently, the adjustment instructions are fed back to the winding software 16 as output results in real time.

[0068] The calculation methods for the winding position and winding spacing are as follows:

[0069] Assuming the starting coordinates of the winding are known, denoted as (x0, y0, r0), and the coordinates of the next winding position are denoted as (x1, y1, r1), the thickness deviation is denoted as ΔH, and the weight deviation is denoted as ΔG. The thickness deviation is calculated as follows: the standard curve for each winding is known, denoted as f(x), and the scanning curve for each winding is denoted as g(x). The thickness deviation ΔH = f(x) - g(x). The standard curve f(x) is determined based on the standard thickness value, and the scanning curve g(x) is determined based on the actual thickness value.

[0070] The winding spacing includes: ΔX out, ΔY out, and ΔR out;

[0071] Where, ΔX out=Kx ΔH+Wx ΔG, ΔY out=Ky ΔH+Wx ΔG, ΔR out=Kr ΔH+Wx ΔG;

[0072] The position of the next wrapping loop is determined as follows:

[0073] x1=x0+ΔX out, y1=y0+ΔY out, r1=r0+ΔR out, where Kx, Ky, Kr, and Wx are weighting coefficients.

[0074] Step S404: Control commands are issued in real time.

[0075] The winding software 16 transmits the tread winding parameter adjustment command fed back by the winding algorithm module 15 to the PLC controller 13 in real time as a control signal. After receiving the control signal (i.e. the tread winding parameter adjustment command), the PLC controller 13 sends it to the drive motor, feeding mechanism, positioning mechanism and other execution components of the tread winding machine 11 to ensure that the tread winding parameter adjustment command is implemented quickly.

[0076] The tread winding parameter adjustment command is a command issued by the tread winding machine when it makes the next wrap, which is the wrap after the current wrap.

[0077] Step S405, Real-time Equipment Execution and Data Feedback:

[0078] Each actuator of the tire tread winding machine 11 executes corresponding actions in real time according to the control signals (i.e., tire tread winding parameter adjustment commands) issued by the PLC controller 13, completing the precise adjustment of the tire tread winding parameters for each turn, ensuring that the thickness, width, weight, and other parameters of the current tire tread meet the standard requirements. At the same time, the vision sensor 14 continuously collects the actual data of the adjusted tire tread winding in real time, repeating the above steps S401 to S404, forming a complete real-time closed-loop control of "data acquisition → data interaction → algorithm calculation → command issuance → equipment execution → data re-acquisition" until the entire tire tread winding operation is completed, realizing real-time adjustment of each tire tread turn throughout the process, avoiding the accumulation of deviations.

[0079] Through the embodiments disclosed herein, visual sensing technology can be applied to tire tread winding machines to achieve real-time acquisition of tread data (thickness, width, weight, etc.) for each turn during the winding process. This eliminates the traditional offline contour calculation and fixed parameter issuance control mode, and constructs a complete real-time closed-loop control process of "data acquisition → data interaction → algorithm calculation → command issuance → equipment execution". This enables real-time adjustment of tread winding parameters, improves production efficiency, reduces labor costs, and achieves quality traceability.

[0080] To address the problems of poor flexibility, reliance on manual intervention, and difficulty in quality traceability in existing offline control methods for tire tread wrapping machines, this disclosure provides a control method for a tire tread wrapping machine, such as... Figure 5 As shown, the method includes the following steps:

[0081] Step S501: Obtain the actual tread winding data of the tire after each turn of the tread winding machine wraps the target tire;

[0082] Step S502: Compare the actual tread wrapping data with the preset standard data to determine the deviation value between the actual tread wrapping data and the preset standard data.

[0083] Step S503: Determine the corresponding tread winding parameter adjustment command based on the deviation value;

[0084] Step S504: Send a tread winding parameter adjustment command to the tread winding machine to control the tread winding machine to perform tread winding according to the winding method corresponding to the tread winding parameter adjustment command.

[0085] Optionally, when the tire tread wrapping machine wraps the tire tread one turn at a time, assuming the current wrapping number is the 1st turn, after the 1st turn is wrapped, the actual tread wrapping data after the 1st turn is wrapped is obtained, and the actual tread wrapping data is compared with the preset standard data (or preset target value) to obtain the difference between the two, i.e., the deviation value.

[0086] In one optional embodiment, the actual tread winding data includes the current thickness and current width of the target tire, and the preset standard data includes the standard thickness and standard weight of the target tire. The actual tread winding data is compared with the preset standard data to determine the deviation value between the actual tread winding data and the preset standard data. This includes: determining the current weight value based on the current thickness and current width; comparing the current weight value with the standard weight value to obtain a weight deviation value; determining the actual scanning curve corresponding to the target tire after each winding turn based on the current thickness value; and determining the thickness deviation value based on the actual scanning curve and the standard scanning curve, wherein the standard scanning curve is determined based on the standard thickness value. The deviation value includes both the thickness deviation value and the weight deviation value.

[0087] Optionally, the above-mentioned actual tread winding data refers to the data corresponding to the current winding turn, which includes the current thickness value (i.e., actual thickness) and current width value (i.e., actual width) of the target tire. The above-mentioned preset standard data can also be referred to as preset target values, including the standard thickness value (i.e., target thickness) and standard weight value (i.e., target weight) of the target tire.

[0088] The current weight value is calculated based on the current thickness and width values ​​to obtain the current volume value (i.e., actual volume) of the target tire. Then, the current weight value is calculated based on the current volume value and the density of the rubber compound used for tire tread winding.

[0089] By comparing the actual tread winding data with preset standard data, the deviation between the two can be determined. Specifically, by comparing the current weight value with the standard weight value, the weight deviation value can be obtained.

[0090] The thickness deviation can be determined based on the difference between the standard scanning curve and the actual scanning curve. The actual scanning curve corresponding to the target tire after each wrap is determined based on the current thickness value, while the standard scanning curve is determined based on the standard thickness value.

[0091] Based on the calculated deviation value, an adjustment command for the tread winding parameters of the tread winding machine is determined. In one optional embodiment, determining the corresponding tread winding parameter adjustment command based on the deviation value includes: determining the winding spacing and winding position corresponding to the next winding turn based on the deviation value; and generating the tread winding parameter adjustment command based on the winding spacing and winding position.

[0092] Optionally, the tread winding parameter adjustment commands are related to the structure included in the tread winding machine. The tread winding machine includes a positioning mechanism.

[0093] Accordingly, the winding spacing and winding position of the positioning mechanism can be determined based on the deviation value.

[0094] For example, if there is a deviation between the actual thickness and the target thickness, and a deviation between the actual weight and the target weight, the tread winding machine needs to be adjusted so that the thickness of the rubber compound matches the target thickness when winding the next tread. This can be achieved by adjusting the winding spacing and position of the positioning mechanism to ensure that the rubber compound in the next winding round meets the target thickness and weight. Based on the winding spacing and position of the positioning mechanism, tread winding parameter adjustment commands can be generated.

[0095] Optionally, the tread winding machine also includes a drive motor and a feeding mechanism. These three components work together to precisely control the amount of rubber compound to be wound around the target tire tread for each turn. When a deviation occurs, the winding spacing and position of the positioning mechanism can be determined based on the deviation value. Based on the winding spacing and position of the positioning mechanism, adjustment commands can be generated for the positioning mechanism. Based on the winding speed of the drive motor, adjustment commands can be generated for the drive motor (e.g., maintaining a constant winding speed). Based on the feeding speed of the feeding mechanism, adjustment commands can be generated for the feeding mechanism (e.g., maintaining a constant feeding speed). Tread winding parameter adjustment commands are then generated based on these three adjustment commands.

[0096] The tread winding parameter adjustment command obtained through the above method needs to be sent to the tread winding machine via data interaction. Once the tread winding machine receives the tread winding parameter adjustment command, it can perform the next tread winding based on it.

[0097] Through the embodiments of this disclosure, on the one hand, by acquiring actual data of tread winding in real time, tread winding parameter adjustment instructions are calculated in real time, and the tread winding parameter adjustment instructions are used to realize real-time adjustment of the tread winding machine, which is highly flexible, improves the production quality and efficiency of tire tread, and reduces labor costs; on the other hand, based on the connection method of real-time closed-loop control process, real-time adjustment of each tread turn is realized, avoiding the accumulation of deviations.

[0098] In one optional embodiment, determining the winding spacing and winding position corresponding to the next winding turn based on the deviation value includes: determining the winding spacing according to the following method: ΔX out=Kx ΔH+Wx ΔG; ΔY out=Ky ΔH+Wx ΔG; ΔR out=Kr ΔH+Wx ΔG; where the winding spacing includes ΔXout, ΔYout and ΔRout, ΔH is the thickness deviation value, ΔG is the weight deviation value, and Kx, Ky, Kr and Wx are weighting coefficients;

[0099] The winding position is determined as follows: x1=x0+ΔX out; y1=y0+ΔY out; r1=r0+ΔR out; where (x0, y0, r0) are the coordinates corresponding to the current winding loop, and (x1, y1, r1) are the coordinates corresponding to the next winding loop. The coordinates corresponding to the next winding loop are the winding position.

[0100] For details on how to determine the winding spacing and winding position, please refer to the previous description, which will not be repeated here.

[0101] In one optional embodiment, acquiring actual tread winding data after each turn of the tread winding machine wraps the target tire includes: receiving an image acquisition signal sent by a programmable logic controller (PLC); sending an image acquisition signal to a vision sensor to activate the vision sensor based on the image acquisition signal, wherein the vision sensor starts performing image acquisition after receiving an image acquisition command, the image acquisition command being sent to the vision sensor by an encoder mounted on the winding drum, the target tire being placed on the winding drum, and the encoder being used to send an image acquisition command to the vision sensor after the tread winding machine has wrapped one turn; and receiving the actual tread winding data sent by the vision sensor.

[0102] Optional, such as Figure 1 As shown, the PLC controller 13 sends control commands, specifically start winding commands, to the tire winding machine 11 and the winding drum 12. Based on the received start winding commands, the tire winding machine 11 and the winding drum 12 begin winding the tread of the target tire. Simultaneously with starting the tread winding of the target tire, the PLC controller 13 sends an image acquisition signal to the vision software 17. Upon receiving this image acquisition signal, the vision software 17 sends the same signal to the vision sensor 14, which then activates based on the received image acquisition signal. The vision sensor is fixedly mounted on the winding drum, and its viewing angle completely covers the tread winding area of ​​the winding drum.

[0103] An encoder is installed on the winding drum 12. The encoder can determine whether the tire winding machine has wound a circle of rubber material. When the encoder confirms that a circle of rubber material has been wound, it synchronously sends an image acquisition command to the vision sensor 14.
