Description

Technical Field

[0001] The invention relates to a tire film sealing packaging production control method, and in particular to a tire film sealing packaging control system and a control method with adaptive size. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machines. They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. When tires are produced, they need to be transported to various places for sale or use. In order to ensure the safety of tires during transportation and avoid friction, the tires will be packaged.

[0003] Traditional film packaging methods mainly include manual packaging and semi-automatic packaging equipment. Manual packaging is inefficient and the quality is difficult to guarantee; and although semi-automatic packaging equipment improves packaging efficiency, it is usually unable to automatically adjust packaging parameters when facing tires of different models and sizes. It is necessary to manually change or adjust the size and position of the film material, which is cumbersome to operate.

[0004] The Chinese invention previously applied by the applicant (publication number: CN118405309A, publication date: 2024-07-30) discloses a tire film sealing packaging machine. The packaging machine includes a frame and a film feeding mechanism, a hot melt film cutting mechanism, a tire conveying mechanism and a heat shrinking mechanism arranged on the frame; one end of the frame is set as an input end, and the other end is set as an output end; the film feeding mechanism includes an upper film feeding unit and a lower film feeding unit; the hot melt film cutting mechanism includes an upper film cutting unit and a lower rubber pad unit; the tire conveying mechanism includes a fixing unit and a transmission unit; the heat shrinking mechanism includes a heat shrinking shell, a heating unit and a plastic sealing unit; wherein the hot melt film cutting mechanism has at least two states, state one is to wrap the heat shrinking film circumferentially on the tire tread, and state two is to cut the heat shrinking film that wraps the tire; the film sealing packaging machine can more conveniently and quickly attach the heat shrinking film to the tire surface.

[0005] The film sealing and packaging machines of this patent mostly use fixed-size films for sealing, but tires have different diameters. If the same length of film is used for packaging, the film may be too long or too short, which will affect the quality of the film sealing, and even cause the film sealing to crack or loosen, and fail to effectively protect the tire. In addition, the existing film sealing and packaging machines lack an intelligent recognition system and cannot identify the specific model and size of the tire. Not only can they not automatically adapt to different tire specifications, but they also cause fluctuations in packaging quality. Summary of the invention

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0021] It should also be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition and explanation in subsequent drawings.

[0022] The specific implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] A film sealing and packaging control system that is adaptive to tire size, the system includes a control system connected to a tire film sealing and packaging machine, such as Figures 1 to 9 As shown, the tire film sealing and packaging machine includes a packaging machine frame 1, a film feeding mechanism 2, a hot-melt film cutting mechanism 3, a tire conveying mechanism 4 and a heat shrinking mechanism 5. The packaging machine combines the functions of film sticking, film cutting and film melting. By using the packaging machine to seal and package tires, the tires can be directly converted from a storage state to a transportable state, saving a lot of time.

[0024] Specifically, according to the shape of the frame 1, its two ends are defined as an input end and an output end respectively, and the movement direction from the input end to the output end is the transportation direction of the packaging machine.

[0025] like Figures 1 to 9 As shown, the tire conveying mechanism 4 is arranged along the transport direction of the packaging machine, and includes a fixing unit 41 for fixing the tire and a conveying unit 42 for transmitting the tire. The conveying unit 42 is installed on the frame 1 and arranged along the input end and the output end of the frame 1, and a plurality of evenly distributed fixing units 41 are arranged on the conveying unit 42.

[0026] Specifically, the conveying unit 42 includes a driving motor 401, a chain 402, an active roller 403, a passive roller 404 and a gear 405; the active roller 403 and the passive roller 404 are horizontally arranged on the frame 1 and the arrangement direction is perpendicular to the conveying direction of the packaging machine, the gear 405 is installed on both ends of the active roller 403 and the passive roller 404, and the driving motor 401 is arranged on the frame 1 and is connected to the active roller 403 through the gear 405.

[0027] The fixing unit 41 includes a first fixing shaft 406 and a second fixing shaft 407. Both ends of the first fixing shaft 406 and the second fixing shaft 407 are fixedly connected to the chains 402 on the left and right sides, respectively, and a certain retention space is provided between the first fixing shaft 406 and the second fixing shaft 407. By providing the first fixing shaft 406, the second fixing shaft 407 and the retention space, the tire can be well mounted on the fixing unit 41, and the subsequent film application, film cutting and film melting of the tire are more convenient.

[0028] The length of the reserved space between the first fixed shaft 406 and the second fixed shaft 407 is smaller than the diameter of the tire, so as to ensure that the tire will not fall onto the fixing unit 41 .

[0029] When the packaging machine needs to seal the tire, the tire needs to be placed on the tire conveying mechanism 4, and the tire is transported to other mechanisms through the tire conveying mechanism 4.

[0030] like Figures 1 to 4 As shown, the film feeding mechanism 2 includes an upper film feeding unit 21 and a lower film feeding unit 22. The upper film feeding unit 21 is arranged above the input end, and the lower film feeding unit 22 is arranged below the input end.

[0031] Specifically, the upper film feeding unit 21 includes an upper film feeding motor 201, an upper film feeding active roller 202, an upper auxiliary roller 203, an upper film swinging rod 204 and an upper micro switch. The upper film feeding motor 201 is installed on the top of the frame 1, and the upper film feeding motor 201 is connected to the upper film feeding active roller 202 by transmission. The upper film feeding active roller 202 is transversely arranged on the frame 1, and the arrangement direction is perpendicular to the conveying direction of the packaging machine. The upper auxiliary roller 203 is installed on the frame 1 and transversely parallel to the upper film feeding active roller 202. The upper film swinging rod 204 is arranged below the upper film feeding active roller 202; an upper micro switch is arranged on one side of the frame 1, and the upper micro switch is used to detect whether the upper film swinging rod 204 swings.

[0032] The lower film feeding unit 22 includes a lower film feeding motor 206, a lower film feeding active roller 207, a lower auxiliary roller 208, a lower film swinging rod 209 and a lower micro switch. The lower film feeding motor 206 is installed at the bottom of the frame 1, and the lower film feeding motor 206 is connected to the lower film feeding active roller 207 by transmission. The lower film feeding active roller 207 is transversely arranged on the frame 1, and the arrangement direction is perpendicular to the conveying direction of the packaging machine. The lower auxiliary roller 208 is installed on the frame 1 and transversely parallel to the lower film feeding active roller 207. The lower film swinging rod 209 is arranged below the lower film feeding active roller 207; a lower micro switch is arranged on one side of the frame 1, and the lower micro switch is used to detect whether the lower film swinging rod 209 swings.

[0033] Before starting the packaging machine, two heat shrink film rolls need to be placed between the upper film feeding active roller 202 and the upper auxiliary roller 203, and between the lower film feeding active roller 207 and the lower auxiliary roller 208, respectively. In order to better fix the two film rolls, film retaining rings 211 are provided at both ends of the upper film feeding active roller 202 and the lower film feeding active roller 207. The film retaining rings 211 are provided to limit the fixed position to the left and right, so that it can only rotate.

[0034] The upper film feeding unit 21 further includes a first film winding roller 212 and a second film winding roller 213 which are arranged on the frame 1 and used for winding the heat shrink film, and the first film winding roller 212 and the second film winding roller 213 are both located below the upper film feeding active roller 202. The specific effects of the first film winding roller 212 and the second film winding roller 213 will be described later.

[0035] like Figure 1 to Figure 2As shown, in order to better ensure that the heat shrink film can perfectly wrap the tire, an inlet working platform 6 is also provided at the input end of the frame 1, and the output port of the inlet working platform 6 is located at the middle of the heat shrink film. The above-mentioned inlet working platform 6 includes a platform bracket 61, a platform plate 62, a guide seat 63 and a guide rod 64. The platform bracket 61 has two pieces and is relatively arranged at the top of the inlet of the input end of the frame 1, and the two ends of the platform bracket 61 are respectively facing the input end and the output end. The platform plate 62 is installed on the top of the platform bracket 61, and the guide seat 63 has two pieces and is relatively fixed in the middle of the platform bracket 61. The opposite surfaces of the two guide seats 63 are provided with fixedly connected guide rods 64.

[0036] Combined with the above description, since the output port of the entrance working platform 6 is directly opposite to the middle of the heat shrink film, when the tire needs to be sealed and packaged, the tire only needs to be pushed vertically into the entrance working platform 6, and the crown of the tire will abut against the center of the heat shrink film. This setting can reduce the time for workers to place tires and improve work efficiency.

[0037] like Figures 1 to 6 As shown, the hot melt film cutting mechanism 3 is arranged above the tire conveying mechanism 4 with the upper and lower parts opened, and has at least two states; in state one, the hot melt film cutting mechanism 3 is opened at the upper and lower parts, and the tire conveying mechanism 4 vertically feeds the spliced ​​heat shrink film into the tire, and as the tire moves forward, the tire tread is circumferentially wrapped with the heat shrink film; in state two, the hot melt film cutting mechanism 3 is closed at the upper and lower parts, and the heat shrink films on the upper film feeding unit 21 and the lower film feeding unit 22 are respectively introduced into the hot melt film cutting mechanism 3, and the upper and lower heat shrink films are hot-melt spliced ​​on the hot melt film cutting mechanism 3, and the heat shrink film wrapped around the tire is cut off; Specifically, the hot melt film cutting mechanism 3 includes an upper hot melt film cutting unit 31 and a lower silicone seat unit 32; the upper hot melt film cutting unit 31 is installed above the input end and is located behind the upper film feeding unit 21, and the lower silicone seat unit 32 is installed below the input end and is located behind the lower film feeding unit 22, and the upper hot melt film cutting unit 31 and the lower silicone seat unit 32 are arranged to be separated from each other. When the upper hot melt film cutting unit 31 and the lower silicone seat unit 32 are respectively started, the two will abut against each other.

[0038] Specifically, the upper hot melt film cutting unit 31 includes an upper cylinder 301, an upper middle knife beam 302, an upper film cutting guide rod 303, an upper slider seat 304, an upper knife holder 305, an upper cutter 306 and a heating element 307; the upper film cutting guide rod 303 is provided with two groups and is vertically arranged on the left and right sides of the frame 1, the upper slider seat 304 is slidably connected to the upper film cutting guide rod 303, the upper middle knife beam 302 is mounted on the upper slider seat 304 on the left and right sides, the upper cylinder 301 is arranged above the upper middle knife beam 302 and is transmission-connected to the upper middle knife beam 302, the upper knife holder 305 is arranged below the upper middle knife beam 302, and the upper cutter 306 and the heating element 307 are installed at the bottom of the upper knife holder 305, and the heating element 307 conducts heat to the upper cutter 306.

[0039] The lower silicone seat unit 32 includes a lower cylinder, a lower reinforcing plate 308, a lower film cutting guide rod, a lower slider seat and a silicone strip 309. The lower film cutting guide rod is provided with two groups and is vertically arranged on the left and right sides of the frame 1. The lower slider seat is slidably connected to the lower film cutting guide rod. The lower reinforcing plate 308 is mounted on the lower slider seats on the left and right sides. The lower cylinder is arranged below the lower reinforcing plate 308 and is transmission-connected to the lower reinforcing plate 308. The silicone strip 309 is installed on the top surface of the lower reinforcing plate 308. The upper cutting knife 306 and the silicone strip 309 are located on the same vertical plane.

[0040] like Figures 1 to 8 As shown, the heat shrink mechanism 5 is arranged at the rear end of the hot melt film cutting mechanism 3, and the tire conveying mechanism 4 is arranged through the heat shrink mechanism 5. The heat shrink mechanism 5 includes a heat preservation cavity 501 and a hot blowing device. The blowing port of the hot blowing device is arranged on the side wall of the heat preservation cavity 501, and the hot air is blown to the sidewall of the tire, so that the heat shrink film shrinks and wraps on the sidewall.

[0041] The above-mentioned hot air blowing device includes a heat shrinkable shell 51, a heating and cooling component 52 and a circulating fan component 53; the heat shrinkable shell 51 is installed in the middle of the frame 1, and the heating and cooling component 52 is arranged inside the heat shrinkable shell 51, and the circulating fan component 53 is arranged on the top of the heat shrinkable shell 51, and extends upward from the inside of the heat shrinkable shell 51 to the outside of the heat shrinkable shell 51.

[0042] Specifically, an insulation cavity 501 is provided between the rack 1 and the heat shrinkable shell 51, and a receiving cavity and a vent 502 are provided on the heat shrinkable shell 51. The receiving cavity is arranged inside the heat shrinkable shell 51, and the vent 502 is used to connect the insulation cavity 501 and the receiving cavity, so that the heating and cooling component 52 can better transfer the heat to the insulation cavity 501 through the vent 502.

[0043] The heating and cooling assembly 52 includes a heating tube 503 and a cooling fan 504 . The heating tube 503 is provided in a plurality of groups and is evenly distributed in the accommodating cavity. The cooling fan 504 is installed on the heat shrinkable shell 51 and is located in the heat preservation cavity 501 .

[0044] The circulation fan assembly 53 is provided with several groups and is evenly distributed on the top of the heat shrinkable shell 51. The circulation fan assembly 53 includes a circulation fan 505, an asbestos cover 506 and a centrifugal fan 507 which are sequentially combined in upper and lower order. The circulation fan assembly 53 is clamped on the top of the heat shrinkable shell 51 through the asbestos cover 506, and the centrifugal fan 507 is connected to the insulation cavity 501.

[0045] like Figures 1 to 8 As shown, in order to better ensure that the heat shrink film can perfectly and firmly fit on the outer surface of the tire, a high-temperature curtain 508 is provided on the heat shrink shell 51. The high-temperature curtain 508 is installed on both ends of the heat shrink shell 51 close to the input end and the output end. By providing these two high-temperature curtains 508, the high-temperature hot air in the insulation cavity 501 is not easy to escape, which better ensures that the temperature in the insulation cavity 501 is within a relatively constant temperature range.

[0046] A plurality of slits 509 are provided on the high temperature cord fabric 508, and the slits 509 can facilitate the tire to enter and exit.

[0047] like Figures 1 to 10 As shown, combined with the above packaging machine, the specific packaging operation process is as follows: First, take out two heat shrink film rolls, place one between the upper film feed active roller 202 and the upper auxiliary roller 203 and limit it using the film retaining ring 211 on the upper film feed active roller 202, and place the other between the lower film feed active roller 207 and the lower auxiliary roller 208 and limit it using the film retaining ring 211 on the lower film feed active roller 207.

[0048] Then, the openings of the two film rolls are torn open and the heat shrink films are respectively wound on the upper film swing rod 204, the first film winding roller 212, the second film winding roller 213 and the lower film swing rod 209, and then the open ends of the two heat shrink films are placed in the middle of the hot melt film cutting mechanism 3, the upper film feeding motor 201 is started to drive the upper hot melt film cutting unit 31 to move downward and the lower film feeding motor 206 is started to drive the lower silicone seat unit 32 to move upward. When the upper cutter 306 and the silicone strip 309 abut against the heat shrink film, the heating element 307 will heat-melt the two heat shrink films together, and the excess part will be cut off by the upper cutter 306. After the cutting is completed, the hot melt film cutting mechanism 3 will be reset.

[0049] At this time, the tire can be vertically input from the entrance working platform 6, and when the tire passes through the guide seat 63 and the guide rod 64, it is exactly located at the center of the heat shrink film, and its crown abuts against the heat shrink film. Under the influence of potential energy, the tire will then fall on the first fixed shaft 406 and the second fixed shaft 407, and be vertically stuck in the retention space.

[0050] By starting the conveying unit 42, the tire moves one body position, and the upper film swing rod 204 and the lower film swing rod 209 are driven to swing at the same time. After the upper microswitch and the lower microswitch detect the swing of the film swing rod, they will drive the upper film feed motor 201 and the lower film feed motor 206 to start, and the heat shrink film will be transported out through the upper film feed active roller 202 and the lower film feed active roller 207.

[0051] When the upper and lower heat shrink films wrap the outer diameter of the tire during movement, the hot melt film cutting mechanism 3 is started again to cut off the wrapped heat shrink film, and the hot melt film cutting mechanism 3 is reset after the cutting is completed. (The above is controlled by setting other micro switches for induction) After wrapping the tire, the conveying unit 42 will convey the tire on the fixing unit 41 into the heat shrinkable housing 51 of the heat shrinking mechanism 5, and completely adhere the heat shrinkable film to the tire surface through the heating and cooling component 52 and the circulating fan component 53. At this time, the heat shrinkable film wraps the crown, shoulder, sidewall and bead of the tire, and extends to the center to protrude the bead, and the protruding length is 1.0-6.0 cm.

[0052] After completion, the tires are transported out of the output end by the conveying unit 42. Since the fixing units 41 are evenly spaced on the conveying unit 42, the tires to be packaged can be continuously sealed and packaged before the heat shrink film is used up.

[0053] In order to better match the film cutting length to the tire size, the control system of the present invention also includes a visual recognition system. The visual recognition system includes a camera 11 installed above the input end of the frame. The camera 11 is used to collect image information of the outer contour and pattern characteristics of the tire, and obtain the diameter, width and pattern details of the tire. The control system connects the visual recognition system and the hot melt film cutting mechanism 3, and recognizes the tire size information based on the image data collected by the camera.

[0054] The control system has an embedded deep learning algorithm module that analyzes the images captured by the camera, extracts the tire pattern features and classifies them to identify the tire model and wear status. The algorithm uses a convolutional neural network (CNN) to train the pattern features and can accurately identify different types of tires. The control system calculates the film length L and the delayed film cutting time T based on the identified size information. delay When the tire is conveyed to the film cutting position and the infrared sensor is triggered, the control system performs delayed film cutting so that the film length matches the tire size.

[0055] Furthermore, in order to accurately identify the diameter and thickness of the tire, the control system of the present invention also includes a laser rangefinder sensor and an infrared sensor. The laser rangefinder sensor is arranged in the horizontal and vertical directions of the tire conveying mechanism, and is used to scan the outer contour of the tire in real time to obtain the diameter and thickness information. The infrared sensor is installed on the top and side of the frame, and is used to detect the width of the tire, and transmit the detection data to the control system for width measurement. The control system adjusts the position of the tire in the conveying mechanism according to the data of the laser and infrared sensors to ensure that the film sealing and film cutting operations are aligned with the center of the tire, thereby improving the packaging accuracy. The control system is equipped with a barcode scanner to read the tire barcode information and match it with the database in the control system to obtain the preliminary size and model of the tire. The control system automatically records the barcode information and identification data (size, model, pattern characteristics), and generates a packaging and quality report for each tire, which is convenient for tracing product history and optimizing production processes.

[0056] Furthermore, the tire film sealing and packaging machine of the present invention installs a tension sensor on the film material transmission path to monitor the tensioning state of the film material in real time; the control system automatically adjusts the output power of the film feeding motor according to the size and pattern characteristics of the tire, so that the film material tension is always in the optimal range, ensuring that the film material is uniform and flat and fits the tire surface during film sealing, thereby avoiding wrinkles or stretching damage of the film material.

[0057] A control method for a tire film packaging with an adaptive size of the present invention comprises the following steps: 1) Start the film sealing and packaging process, collect the external dimensions and pattern feature information of the tire through the camera, and use the control system to analyze the image data to identify the tire's diameter, width, thickness and pattern feature information; 2) The control system determines whether the tire model and size information is successfully identified. If the identification is successful, the tire diameter, width and barcode information are extracted, and the barcode information is matched with the model data in the database; if the identification fails, a manual intervention is prompted; 3) Calculate the required film length L based on the identified tire size information. The calculation formula is: L=C+margin Where C is the circumference of the tire outer contour, and the margin is used to ensure that the film material covers completely and prevent the tensioning force from affecting the sealing effect; 4) Calculate the delayed film cutting time T according to the film length L and conveying speed V delay ; ; 5) The tire is conveyed to the film cutting position through the conveying device. When the infrared sensor detects that the tire has reached the film cutting position, the control system receives the trigger signal and delayThen start the hot melt film cutting mechanism to perform the film cutting operation so that the film cutting length accurately matches the tire size; 6) After the film cutting is completed, the control system continues to control the conveying device to convey the tire to the heat shrinking mechanism position, and starts the hot air blowing device to perform heat shrinking film sealing operation, so that the film material shrinks evenly on the tire surface; 7) After the film sealing is completed, a packaging and quality report is generated and saved, which includes the tire size, model, pattern characteristics and film sealing status for quality traceability and production management.
