Description

Technical Field

[0001] This application relates to the field of tire and rubber product manufacturing equipment technology, and in particular to a double-layer rubber transport and deployment device. Background Technology

[0002] In the manufacturing process of rubber products such as tires, the processing and handling of rubber sheets directly affects the quality of the final product. After being shaped into blocks, the rubber sheets need to enter a rubber sheet cooling line for cooling, stacking, and curing. After curing, they are transferred to subsequent processes. At the end of the rubber sheet cooling line, the stacking device plays a crucial role in evenly stacking the cooled rubber sheets onto a rubber tray. The condition of the rubber sheets before stacking directly determines the stacking effect and the stability of subsequent processes.

[0003] Currently, the mainstream glue-positioning solutions on the market adopt a combined structure of "transport device + glue-positioning device", such as... Figure 1 As shown, its workflow is as follows: the transport device grabs the film from the coating cooling rack and conveys it above the coating placement device; then the transport device continues to convey the film, causing it to fall into the hopper of the coating placement device, triggering photoelectric detection during the film's descent; finally, the hopper moves left and right, placing the film in an S-shape on the film tray. However, this solution has significant drawbacks in practical applications: First, existing solutions are completely incapable of handling the double-layer adhesive problem. Because the film conveyed by the transport device may form a double-layered state due to factors such as the gripping angle and the film's adhesiveness, and existing processes lack a mechanism for unfolding the double-layer adhesive, the double-layer adhesive directly enters the adhesive placement device.

[0004] Secondly, double-layer adhesive is prone to causing blockage. The thickness of double-layer adhesive is much greater than that of single-layer adhesive. During the process of entering the hopper or falling onto the adhesive tray, it is easy to get stuck at the outlet of the hopper or the edge of the adhesive tray, causing blockage of the conveying channel. This requires manual shutdown for cleaning, which seriously affects the continuity of production.

[0005] Furthermore, uneven film stacking poses a risk of the film tray tipping over. The glue tip of the double-layer adhesive may split during placement, resulting in inconsistent initial placement of the film on both sides. This uneven thickness during subsequent stacking causes the film tray's center of gravity to shift. When the film tray is stacked to a certain height, this shift in center of gravity can easily cause the tray to tip over, not only wasting film but also potentially damaging equipment or causing safety accidents.

[0006] In summary, the existing film cooling line coating process has significant technical shortcomings in double-layer adhesive processing, resulting in low production efficiency, frequent failures, and limited applicability. There is an urgent need for a simple, cost-effective, and highly adaptable double-layer adhesive spreading process to solve these problems. Utility Model Content

[0007] The purpose of this utility model application is to provide a double-layer adhesive transport and unfolding device, which overcomes the defect that the existing film cooling line stacking process cannot handle double-layer adhesive, so as to realize the automatic unfolding of double-layer adhesive, avoid adhesive blockage, ensure that the film is stacked flat, and has the characteristics of simple structure, low installation space requirement, low economic cost and strong adaptability.

[0008] This application provides a double-layer adhesive transport and unfolding device, which includes: a clamping transport device for transporting and holding adhesive sheets and an adhesive arranging device for evenly placing the adhesive sheets onto an adhesive tray; the clamping transport device is equipped with a drive motor for driving the clamping transport device to transport in a first predetermined direction and a second predetermined direction; wherein the first predetermined direction and the second predetermined direction are two opposite directions; a reflective photoelectric detection mechanism for detecting the position of the adhesive sheets is provided on the side of the clamping transport device near the adhesive arranging device; and a control system is further included, which is electrically connected to the drive motor of the clamping transport device, the reflective photoelectric detection mechanism, and the adhesive arranging device respectively. After receiving the adhesive sheet information detected by the reflective photoelectric detection mechanism, the control system controls the drive motor to drive the clamping transport device to transport in the second predetermined direction.

[0009] In this application, the clamping and transporting device realizes the film conveying and clamping, the reflector photoelectric detection mechanism provides precise position trigger signals, the glue-laying device completes the final uniform stacking, and the control system coordinates the collaborative work of each device, providing a basic guarantee for the double-layer glue unfolding from the hardware and control logic levels, realizing the upgrade from "single device action" to "multi-device collaborative automation"; at the same time, the "reflector photoelectric detection + control system controlling the motor forward and reverse rotation" scheme of this application fills the technical gap of double-layer glue unfolding before glue-laying and solves the problem that existing processes cannot handle double-layer glue.

[0010] In one specific implementation scheme, the clamping and transporting device includes an upper clamping belt and a lower clamping belt. The drive motor drives the lower clamping belt to rotate, while the upper clamping belt remains in a non-powered, follow-along state. When the drive motor reverses, the lower clamping belt moves in the opposite direction, causing relative displacement of the double-layer adhesive at the adhesive head to achieve unfolding. Through the design of "lower clamping belt actively driven, upper clamping belt passively followed," the speed difference between the upper and lower clamping belts is used to cause relative displacement of the double-layer adhesive when the drive motor reverses, thus unfolding the adhesive head. At the same time, the non-powered upper clamping belt avoids additional power causing stretching, wrinkling, or other damage to the adhesive sheet, ensuring the integrity of the adhesive sheet.

[0011] In one specific implementation, the reflector photoelectric detection mechanism includes a transmitter and a receiver. The transmitter emits a detection beam perpendicular to the film transport direction. When the film tip blocks the detection beam, the receiver generates a trigger signal and transmits it to the control system. The reflector photoelectric detection mechanism ensures accurate detection of the film tip position, providing a timely trigger signal for motor reversal. This avoids the problem of the film tip passing the detection point without reversal starting due to detection lag, thus preventing the double-layer adhesive from unfolding.

[0012] In one specific implementation scheme, the control system has a built-in program module, which includes a motor reversal duration setting module and a glue-positioning device delay movement setting module. The motor reversal duration setting module presets the time from receiving a trigger signal to the motor stopping its reversal, while the glue-positioning device delay movement setting module presets the delay time from the start of motor reversal to the beginning of the glue-positioning device's movement towards the center. Operators can adjust the motor reversal duration according to the film thickness and length using the motor reversal duration setting module to ensure that films of different specifications can be fully unfolded. Simultaneously, the glue-positioning device delay movement setting module prevents the swivel bucket from starting to move before the double-layer glue has fully unfolded, thus avoiding film misalignment and ensuring accurate glue-positioning.

[0013] In one specific implementation, the glue-positioning device includes a laterally movable hopper. The hopper's movement range covers the lateral width of the glue tray. When the drive motor of the clamping and transporting device stops reversing and resumes forward rotation, the hopper moves to the center position where the film falls. The movement of the hopper ensures that the unfolded single-layer film falls precisely into the center of the hopper, avoiding the problem of film accumulation on one side and emptiness on the other due to hopper offset, which could lead to a shift in the center of gravity of the glue tray.

[0014] In one specific implementation, the inner wall of the hopper of the rubber swivel device is coated with a wear-resistant coating to reduce the coefficient of friction between the rubber sheet and the inner wall of the hopper, thus preventing scratch damage to the rubber sheet during placement. Reducing the coefficient of friction between the rubber sheet and the inner wall of the hopper prevents scratch damage caused by excessive friction within the hopper, while also reducing the accumulation of rubber residue within the hopper, decreasing the cleaning frequency, and extending the service life of the hopper.

[0015] In one specific implementation, the conveying speed of the clamping and conveying device can be adjusted by the control system. The conveying speed is adapted to the thickness and length of the film to ensure that the film is wrinkle-free and does not shift during the conveying process. For films with strong adhesion, the speed can be reduced to prevent the film from sticking to the belt; for films with weak adhesion, the speed can be increased to improve production efficiency while avoiding wrinkles and shifts caused by excessive speed.

[0016] In one specific implementation scheme, the detection height of the reflector photoelectric detection mechanism is adjustable, and the adjustment range is adapted to films of different thicknesses to ensure accurate detection of film heads of different specifications.

[0017] In one specific implementation scheme, the control system has a fault alarm function. When the reflector photoelectric detection mechanism fails to detect the film for a preset period of time, or when the film fails to unfold properly after the clamping and conveying device motor reverses, the system issues an audible and visual alarm signal. This enables real-time monitoring and early warning of equipment abnormalities, preventing energy waste due to film shortages or subsequent glue blockage and stacking abnormalities caused by un-unfolded film.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0021] To facilitate understanding of the double-layer rubber transport and unfolding device provided in this application embodiment, its application scenario is first described. This double-layer rubber transport and unfolding device is applied in the field of tire and rubber product manufacturing equipment technology. In the manufacturing process of tires and other rubber products, the processing and handling of rubber sheets directly affects the final product quality. After the rubber sheets are processed into blocks, they need to enter the rubber sheet cooling line for cooling, stacking, and curing. After curing, they are transferred to subsequent processes. At the end of the rubber sheet cooling line, the rubber stacking device plays a crucial role in evenly stacking the cooled rubber sheets onto the rubber tray. The state of the rubber sheets before stacking directly determines the stacking effect and the stability of subsequent processes. Currently, the mainstream stacking solution on the market adopts a combination structure of "transport device + stacking device." Its workflow is as follows: the transport device grabs the rubber sheet from the rubber cooling rack and transports it above the stacking device; then the transport device continues to transport the rubber sheet, causing it to fall into the stacking bucket of the stacking device. During the descent of the rubber sheet, photoelectric detection is triggered; finally, the stacking bucket moves left and right, placing the rubber sheet in an S-shape on the rubber tray. However, this solution has significant drawbacks in practical applications: First, the existing solution is completely incapable of handling the double-layer adhesive problem. Because the film conveyed by the transport device may form a double-layered state due to factors such as the gripping angle and the adhesive properties of the film, and the existing process lacks a mechanism for unfolding the double-layer adhesive, it directly enters the dispensing device. Second, double-layer adhesive easily causes clogging. The thickness of double-layer adhesive is much greater than that of single-layer adhesive, and during its entry into the dispensing hopper or its descent to the dispensing tray, it is prone to getting stuck at the hopper outlet or the edge of the dispensing tray, causing blockages in the transport channel. This requires manual shutdown for cleaning, severely impacting production continuity. Third, the film stacking is uneven, and there is a risk of the dispensing tray tipping over. The adhesive head of the double-layer adhesive may fork during dispensing, resulting in inconsistent initial placement positions of the film on both sides. Uneven thickness during subsequent stacking causes the center of gravity of the dispensing tray to shift. When the dispensing tray reaches a certain height, this shift in the center of gravity can easily cause the tray to tip over, not only wasting film but also potentially damaging equipment or causing safety accidents. Therefore, this application provides a double-layer adhesive transport and unfolding device, which overcomes the defect that the existing film cooling line stacking process cannot handle double-layer adhesive, so as to realize the automatic unfolding of double-layer adhesive, avoid adhesive blockage, ensure that the film is stacked flat, and has the characteristics of simple structure, low installation space requirement, low economic cost and strong adaptability.

[0022] Therefore, the present application provides a double-layer adhesive transport and unfolding device, which adopts the scheme of "reflector photoelectric detection + control system to control the forward and reverse rotation of the motor", filling the technical gap of unfolding double-layer adhesive before placement and solving the problem that existing processes cannot handle double-layer adhesive.

[0023] like Figures 2-7As shown, the double-layer adhesive transport and unfolding device achieves automatic unfolding of the double-layer adhesive through the cooperation of the clamping transport device 1, the adhesive swaying device 3, the reflector photoelectric detection mechanism 2 and the control system, and through the coordination of the reflector photoelectric detection and the forward and reverse rotation control of the motor.

[0024] In this application, the clamping and transporting device 1 is equipped with a drive motor, which can drive the clamping and transporting device 1 to transport in a first predetermined direction and a second predetermined direction, wherein the first predetermined direction and the second predetermined direction are two opposite horizontal directions. The clamping and transporting device 1 in this application includes an upper clamping belt and a lower clamping belt. The drive motor can drive the lower clamping belt to rotate, while the upper clamping belt is in a non-powered follow-up state; when the drive motor reverses, it causes the lower clamping belt to move in the opposite direction.

[0025] In this embodiment, the clamping and transporting device 1 is a belt-type clamping conveyor. The upper clamping belt is a follower belt supported by a non-powered roller, and the lower clamping belt is driven by a servo motor. The surface of the belt material is provided with anti-slip texture to ensure stable clamping of the film 4 and prevent the film 4 from shifting during transport. The conveying length of the conveyor is set according to the actual layout of the film cooling line, and the width is 10-15cm wider than the largest size film 4 to ensure that the film 4 completely covers the transport area.

[0026] In this application, a reflector photoelectric detection mechanism 2 is provided on the side of the clamping and transporting device 1 near the film-laying device 3. The reflector photoelectric detection mechanism 2 is used to detect the position of the film 4. In this application, the reflector photoelectric detection mechanism 2 includes a transmitter and a receiver. The detection beam emitted by the transmitter is perpendicular to the film 4 transport direction. When the film 4's adhesive end blocks the detection beam, the receiver generates a trigger signal and transmits it to the control system.

[0027] In this embodiment, the reflector photoelectric detection mechanism 2 can be a laser photoelectric sensor. The transmitter and receiver of the laser photoelectric sensor are respectively installed on the two brackets on the side of the clamping and transporting device 1 near the adhesive placement device 3. The detection beam is perpendicular to the conveying direction of the film 4, and the detection height can be moved up and down by the adjustment groove on the bracket. The signal output terminal of the laser photoelectric sensor is connected to the control system through a shielded wire to ensure stable signal transmission.

[0028] This application also includes a control system, which is electrically connected to the drive motor of the clamping and transporting device 1, the photoelectric detection mechanism 2 of the reflector, and the swaying device 3. The control system of this application also includes a built-in program module, which includes a motor reversal duration setting module and a swaying device delay movement setting module. The motor reversal duration setting module is used to preset the time from when the drive motor receives a trigger signal to when it stops reversing, and the swaying device delay movement setting module is used to preset the delay time from when the drive motor starts reversing to when the swaying device 3 moves towards the center.

[0029] In this embodiment, the control system also has a fault alarm function. When the reflector photoelectric detection mechanism 2 fails to detect the film 4 for a preset time period, or when the film 4 fails to unfold normally after the drive motor of the clamping and transporting device 1 reverses, the control system issues an audible and visual alarm signal. Simultaneously, in this embodiment, the control system can adjust the conveying speed of the clamping and transporting device 1, that is, the control system can adjust the rotational speed of the drive motor.

[0030] In this embodiment, the duration during which the reflector photoelectric detection mechanism 2 fails to detect the film 4 is set to 5 seconds. When this duration is exceeded, the control system determines that the film 4 is interrupted and issues an audible and visual alarm. At the same time, by installing an ultrasonic thickness sensor in the swing bucket, the thickness of the film 4 is detected. When the thickness of the film 4 still exceeds 1.5 times the thickness of a single layer of film after the motor reverses, it is determined that the unfolding has failed, and the control system also issues an alarm.

[0031] This application provides a rubber swinging device 3 located below the clamping and transporting device 1. The rubber swinging device 3 includes a swing bucket that can move laterally. The swing bucket's movement range covers the lateral width of the rubber tray. When the drive motor of the clamping and transporting device 1 stops reversing and resumes forward rotation, the swing bucket moves to the center position where the rubber sheet 4 falls.

[0032] In this embodiment, the inner wall of the swing bucket is coated with a 0.1-0.2mm thick polytetrafluoroethylene wear-resistant coating to prevent the film 4 from scratching the inner wall of the swing bucket; and the lateral movement of the swing bucket is driven by a stepper motor, with the movement stroke set according to the diameter of the film tray to ensure that the swing bucket can cover the entire lateral width of the film tray; the feed port of the swing bucket and the discharge port of the clamping and conveying device 1 are aligned in the vertical direction to prevent the film 4 from shifting during the falling process.

[0033] In this embodiment, the delay time of the swing bucket movement is 0.2-0.3 seconds later than the start time of the reverse rotation of the drive motor. The purpose of setting this delay time is as follows: at the initial stage of the reverse rotation of the drive motor, the double-layer adhesive is in the initial unfolding stage, and the swing bucket does not move at this time to avoid starting to swing the adhesive before the film 4 is unfolded; when the delay time ends, the double-layer adhesive has been basically unfolded, and the swing bucket begins to move towards the center to ensure that the swing bucket reaches the center position exactly when the film 4 falls, so as to achieve precise docking.

[0034] In this embodiment, the film 4 is first cooled by the film cooling line, then picked up by the glue gripper and placed between the upper and lower clamping belts of the clamping and transporting device 1, as follows. Figure 2 As shown, at this time, due to the gripping angle of the glue gripper, the glue head of the film 4 forms a double-layer superimposed state; after the staff starts the equipment through the touch screen, the control system sends a forward rotation command to the drive motor driver of the clamping and transporting device 1 after receiving the start signal.

[0035] Then the drive motor rotates forward at the set conveying speed, driving the lower clamping belt to move clockwise. The upper clamping belt follows the movement of the film 4, and the film 4 begins to be conveyed towards the direction of the swaying device 3. Figure 3 As shown; during this process, the control system monitors the speed of the drive motor in real time through the encoder to ensure that the conveying speed is stable and without fluctuations.

[0036] When the film 4's adhesive head moves to the detection area of ​​the reflector photoelectric detection mechanism 2, it blocks the laser beam, such as... Figure 4 As shown, the receiver detects a change in the light signal, generates a trigger signal, and transmits it to the control system. Upon receiving the trigger signal, the control system immediately sends a reverse command to the drive motor driver, causing the drive motor to switch from forward to reverse rotation, and the lower clamping belt to move counter-clockwise. Since the upper clamping belt is unpowered, it only moves slightly with the film 4. The reverse movement of the lower clamping belt causes relative displacement of the double-layered film at the adhesive head. The upper film continues to move slightly forward due to inertia, while the lower film moves backward with the lower belt, and the double-layered adhesive begins to unfold. Figure 5 and Figure 6 As shown.

[0037] Simultaneously with sending the reverse command to the drive motor, the control system starts the swing bucket delay timer, which begins timing according to the set delay time. When the timer reaches the set delay time, the control system sends a movement command to the stepper motor driver of the swing device 3, and the stepper motor drives the swing bucket to move towards the center of the glue tray. After the drive motor continues to reverse for the set duration, the control system sends a stop reverse command to the drive motor driver and switches to a forward rotation command. The drive motor resumes forward rotation, and the lower clamping belt moves clockwise again. At this time, the film 4 has been fully unfolded into a single layer. At the same time, driven by the stepper motor, the swing bucket moves exactly to the center position of the glue tray. The control system detects the position of the swing bucket through the limit switch, and after confirming that it is in place, sends a stop command to the stepper motor, and the swing bucket stops moving. Figure 7 As shown.

[0038] The clamping and transporting device 1 continues to rotate forward, conveying the single-layer film 4 into the swing bucket. The film 4 falls to the bottom of the swing bucket under the action of gravity. The control system sends a reciprocating movement command to the stepper motor, which drives the swing bucket to move back and forth in the horizontal range of the film tray. The film 4 in the swing bucket moves with the swing bucket and is evenly placed on the film tray in an S-shape.

[0039] If the photoelectric detection mechanism 2 of the reflector plate fails to detect film 4 for 5 consecutive seconds during the film 4 transport process, the control system determines that the film 4 transport is interrupted, the touch screen displays the "film missing" alarm message, the red alarm light on the equipment lights up, and the buzzer sounds an alarm; if the ultrasonic thickness sensor in the swing bucket detects that the thickness of film 4 still exceeds 1.5 times the thickness of a single layer of film after the drive motor reverses, the control system determines that the double-layer film unfolding has failed, and the touch screen displays the "unfolding failure" alarm message.

[0040] In this application, the clamping and transporting device 1 realizes the conveying and clamping of the film 4, the reflector photoelectric detection mechanism 2 provides a precise position trigger signal, the glue-laying device 3 completes the final uniform stacking, and the control system coordinates the collaborative work of each device, providing a basic guarantee for the double-layer glue unfolding from the hardware and control logic level, realizing the upgrade from "single device action" to "multi-device collaborative automation"; at the same time, the "reflector photoelectric detection + control system controlling the forward and reverse rotation of the motor" scheme of this application fills the technical gap of double-layer glue unfolding before glue-laying and solves the problem that the existing process cannot handle double-layer glue.
