Technical Field

[0001] This invention relates to the field of tire processing technology, and in particular to a tire processing apparatus and its automatic feeding device for opening the crown strip. Background Technology

[0002] In the tire forming process, a crown strip winding step is required. Current crown strip feeding devices use a drive roller to extract the crown strip from the storage wheel and feed it to the next process. When the crown strip on the material wheel is depleted, a new wheel filled with crown strip needs to be transferred to the material wheel, and the new crown strip is attached to the previous one. This material change requires supervision; if the supervisor is negligent, the crown strip supply will be interrupted, tire production will be halted, and production efficiency will be affected. Furthermore, the new crown strip needs to be sequentially passed through various equipment components according to production requirements before tire production can resume, making the installation cumbersome, time-consuming, and labor-intensive.

[0003] Therefore, how to provide an automatic feeding device for crown strip guide opening to achieve automatic feeding and reduce the labor intensity of operators is a problem that urgently needs to be solved by those in this technical field. Summary of the Invention

Detailed Implementation

[0041] This invention discloses an automatic feeding device for crown strip guides, which enables automatic feeding and reduces the labor intensity of operators. This invention also discloses a tire processing apparatus incorporating the aforementioned automatic feeding device for crown strip guides.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0044] like Figure 1 As shown, Figure 1 This is a schematic diagram of the automatic fabric feeding device for opening and refilling the curtain fabric disclosed in an embodiment of the present invention.

[0045] This application also discloses an automatic feeding device for crown strip guide opening, which includes: crown strip guide opening device 1 and feeding conveyor assembly, wherein the feeding conveyor assembly includes: a bracket, a crown strip material head clamping and conveying device, a material detection device 5, a material tail detection device 7, a suction cup assembly 8, a joint sewing device 14, and a material tail clamping device, all mounted on the bracket and arranged sequentially along the crown strip conveying direction.

[0046] Specifically, the crown strip guide device 1 is equipped with a crown strip roll 2. The guide device 1 can guide the crown strip roll 2 to facilitate subsequent conveying of the crown strip. In practice, the crown strip guide device 1 can be a crown strip trolley, which has the functions of transporting and guiding the crown strip roll 2. To facilitate the guiding of the crown strip roll 2, the crown strip guide device 1 has a material head fixing device for fixing the crown strip head. The material head fixing device can fix the material head to facilitate clamping and prevent the material head from being lost. Specifically, the material head fixing device can be a clamping roller.

[0047] The function of the conveying and feeding assembly in this application is to convey the crown strips opened by the crown strip guide device to the feeding device and realize automatic feeding of crown strips. The suction cup assembly 8 is arranged opposite to the joint sewing device 14. The crown strip material head clamping and conveying device is used to clamp the material head on the crown strip guide device to be conveyed and convey the material head to the suction cup assembly 8. The crown strip guide device 1 is arranged around the circumference of the bracket to facilitate clamping the material heads on different crown strip guide devices 1. The above discloses the relative distribution of the components in the conveying and feeding assembly. The specific assembly method and installation position can be set according to different needs, and all are within the protection scope.

[0048] The aforementioned tail clamping device is used to clamp the crown strip during the conveying process, specifically including a fixed clamping member 12 and a movable clamping member 10. The fixed clamping member 12 is fixed to the bracket and located on the side close to the feeding device, while the movable clamping member 10 can reciprocate along the crown strip conveying direction, specifically moving from an initial position to the fixed clamping member 12 and then returning to the initial position. During operation, the crown strip is conveyed to the feeding device sequentially through the movable clamping member 10 and the fixed clamping member 12. With this configuration, the tail of the crown strip can be clamped and conveyed by the fixed clamping member 12 and the movable clamping member 10, preventing the tail from swaying.

[0049] The aforementioned material detection device 5 is used to detect whether there is a crown strip. When no crown strip is detected, the material tail clamping device clamps the crown strip, and the moving clamping member 10 moves along the guide rail 11 to the fixed clamping member 12 and then releases the crown strip and returns to the initial position until the material tail detection device 7 detects the material tail, and the material tail clamping device releases the crown strip.

[0050] Specifically, the material detection device 5 can be a material-free detection switch. When no crown strip passes by, the material-free detection switch is triggered to close and simultaneously controls the movable clamping member 10 to clamp the material and move it along the crown strip conveying direction. At the same time, it controls the fixed clamping member 12 to clamp the material. By conveying the crown strip from the movable clamping member 10 to the fixed clamping member 12, the conveying of the crown strip can be slowed down and the conveying length of the crown strip can be limited to prevent the crown strip from being conveyed too fast or too much and thus missing the connection with the joint.

[0051] The drive components of the material detection device 5 and the material tail clamping device can be connected via controller signals. The control method is existing technology and is not specifically limited here.

[0052] The aforementioned material tail detection device 7 is used to locate the material tail of the crown strip. When the material tail detection device 7 detects the material tail, the suction cup assembly 8 is activated to fix the material tail, and the material tail clamping device releases the crown strip. Simultaneously, the crown strip material head clamping and conveying device is activated to clamp the material head and convey it to the suction cup assembly 8. Specifically, the material tail detection device 7 can be a material tail detection switch or a material tail sensor. When the material tail passes by, the material tail detection switch or sensor is triggered, controlling the suction cup assembly 8 to start suction, causing the suction cup assembly 8 to adsorb the material tail due to negative pressure. At the same time, the aforementioned material tail clamping device is controlled to release the crown strip, meaning the crown strip is no longer conveyed. The crown strip material head clamping and conveying device is then activated to clamp the material head and convey it to the suction cup assembly 8, facilitating the overlap between the material head and tail. The overlap length between the material head and tail needs to be set according to actual needs and is within the protection range; only the distance the crown strip material head clamping and conveying device moves needs to be adjusted.

[0053] The aforementioned joint sewing device 14 is used to sew the material tail fixed by the suction cup assembly 8 to the material head conveyed by the crown strip material head clamping and conveying device. Specifically, when the crown strip material head clamping and conveying device reaches the preset position, the joint sewing device 14 is activated, and the material head and material tail are overlapped through the sewing of the joint sewing device 14, thereby completing automatic material feeding.

[0054] The specific working process is as follows: The crown strip guide device 1 guides the crown strip roll 2, and then it is conveyed to the feeding device via the conveying and feeding assembly. During the conveying process, when the material detection device 5 detects that there is no crown strip, the tail clamping device clamps the crown strip, and the crown strip is gradually conveyed by the movement of the moving clamping member 10. During the continued conveying of the crown strip, when the tail detection device 7 detects the tail, the suction cup assembly 8 adsorbs the tail, and the tail clamping device releases the crown strip. At the same time, the crown strip head clamping and conveying device conveys the head to the suction cup assembly 8. When the crown strip head clamping and conveying device reaches the preset position, the joint sewing device 14 is activated to complete the sewing, thereby realizing the conveying and automatic feeding of the crown strip.

[0055] As can be seen from the above process, the crown strip guide automatic feeding device in this application can realize the guide and automatic feeding of crown strips without manual operation, which greatly reduces the labor intensity of operators.

[0056] In a specific embodiment, the crown strip material head clamping and conveying device includes: a crown strip material head clamping device 17 and a crown strip material head lifting device 18. The crown strip material head clamping device 17 is used to clamp the material head on the crown strip guide device to be conveyed. The crown strip material head clamping device 17 can slide along the crown strip material head lifting device 18 to the suction cup assembly 8. That is, the function of the crown strip material head clamping and conveying device in this application is to clamp and lift, so as to convey the crown strip to be conveyed to the suction cup assembly 8, where it overlaps and sews with the material tail there.

[0057] Preferably, the crown strip material head lifting device 18 may include a guide rail mounted on a bracket. In order to limit the material head conveying position, a limiting member may be set on the guide rail in practice. When the crown strip material head clamping device 17 abuts against the limiting member, the length of overlap between the material head and the material tail is the required length.

[0058] The crown strip material clamping device 17 in this application includes: a material claw, a horizontal drive device, a swing arm, and a swing drive device.

[0059] The material claw is used to grip the material head. In order to achieve conveying, the material claw in this application is slidably engaged with the crown strip material head lifting device 18. The horizontal drive device drives the material claw to extend and retract in the horizontal direction. The swing arm is connected to the body of the horizontal drive device. The swing drive device drives the swing arm to swing in the vertical plane. The material claw can grip the material head fixed by the material head fixing device through the drive of the swing drive device.

[0060] With the above settings, the swing drive device drives the swing arm to swing along the vertical plane, which can drive the material claw to pick up the material head on the crown strip guide device 1, or directly position the swing arm vertically upward so that the material head of the crown strip picked up by the material claw can be connected with the material tail of the previous crown strip.

[0061] Of course, the crown strip material head clamping device can also be directly set as a robotic arm structure, such as a six-axis robotic arm.

[0062] In a further embodiment, the aforementioned conveying and feeding assembly further includes a material reversing conveyor device. This material reversing conveyor device is used to reverse the direction of the crown strip opened by the crown strip guide device 1 and to limit the crown strip along the conveying direction. The material reversing conveyor device can reverse the direction of the crown strip opened by the crown strip guide device 1, so that the crown strip can run along a preset trajectory. Those skilled in the art will understand that the conveying direction of the crown strip can be set according to actual needs, and all are within the protection scope.

[0063] This application discloses a specific structure of a material reversing conveyor, including a reversing roller 3 and a centering roller. During the conveying of the crown strip, the crown strip guided by the crown strip guiding device 1 passes sequentially through the reversing roller 3 and the centering roller. The function of the reversing roller 3 is to reverse the direction of the crown strip guided by the crown strip guiding device 1, while the function of the centering roller is to ensure that the position of the crown strip is stable after reversal and does not deviate from the preset position. Specifically, the centering roller includes two parallel clamping rollers, and the axis of the reversing roller 3 is perpendicular to the axis of the centering roller. By arranging them perpendicularly, the crown strip can be limited in both directions, preventing the crown strip from detaching from the material reversing conveyor.

[0064] In practice, the axis of the reversing roller 3 and the axis of the centering roller can be set to be parallel or intersecting. The reversing roller 3 corresponds one-to-one with the crown strip guiding device 1, that is, each crown strip guided by the crown strip guiding device 1 will pass through the reversing roller 3 for reversal so that the direction of the crown strip meets the requirements.

[0065] In a further embodiment, the material reversing conveyor also includes a swing assembly 4 for switching workstations. This swing assembly 4 receives the crown strip conveyed by the reversing roller 3 corresponding to its workstation and conveys it to the given intermediate roller. In practice, after the material on the first crown strip guide device is completely conveyed, the material head on the second crown strip guide device needs to be connected to the material tail on the first crown strip guide device for automatic material replenishment. Therefore, to ensure that different crown strip guide devices 1 are received, the position of the swing assembly 4 receiving the material needs to be switched so that the receiving end corresponds to different crown strip guide devices 1. Specifically, as shown... Figure 1 As shown, when conveying the crown strip on the left crown strip guide device 1, the swing assembly 4 is located at the left receiving position. When it is necessary to receive the crown strip on the right crown strip guide device 1, the swing assembly 4 moves to the right receiving position.

[0066] Specifically, the swing assembly 4 includes a fixed bracket with a limiting hole and a swing roller that can move along the limiting hole. During operation, when it is necessary to convey the crown strip on the left side of the crown strip guide device 1, the swing roller moves to the left and clamps the crown strip with the left side wall of the limiting hole; when conveying the crown strip on the right side of the crown strip guide device 1, the swing roller moves to the right and clamps the crown strip with the right side wall of the limiting hole. The reversing roller 3, the swing assembly, and the centering roller are arranged along the material conveying direction.

[0067] The conveying and feeding assembly disclosed in this application also includes a cross-centering roller 6 for tensioning the crown belt strip after passing through the material reversing conveyor. The cross-centering roller 6 includes at least three movable rollers driven by cylinders. These movable rollers are distributed on both sides of the crown belt strip and staggered, allowing the movable rollers on both sides of the crown belt strip to move to the opposite side. The two rows of movable rollers can move crosswise, achieving functions such as crown belt strip centering, material tail storage, and station switching.

[0068] In practice, after the material is conveyed for a certain period of time, the moving roller can be started to move in the opposite direction, so that the crown strip bends into an M shape at the cross centering roller 6 to store the material tail and prevent the splicing from being missed due to the material conveying too fast when the material detection device 5 cannot detect the material.

[0069] In a preferred embodiment, four moving rollers are evenly arranged on both sides of the crown strip. The four moving rollers include three conical rollers and one cylindrical roller. The conical rollers are located between the material detection device 5 and the material tail detection device 7, and the cylindrical roller is located between the material detection device 5 and the centering roller. A specific structure of the cross-centering roller 6 is disclosed herein; however, in practice, the structure of the cross-centering roller 6 can be configured as needed.

[0070] To protect the material detection device 5, the conveying and feeding assembly disclosed in this application further includes a protective clamping roller 16. This protective clamping roller 16 comprises two clamping rollers with parallel axes. During movement, the cylindrical roller can cooperate with the protective clamping roller 16 to clamp the crown strip. This clamping action prevents the tail of the crown strip from colliding with the material detection device 5, thus affecting the accuracy of the material detection device 5. Specifically, there are two protective clamping rollers 16, which can cooperate with the corresponding protective clamping roller 16 to clamp the crown strip during the left-right movement of the cylindrical roller.

[0071] In addition, in order to protect the tail detection device 7, a crown strip limiting roller 15 for clamping the crown strip is provided between the cross centering roller 6 and the tail detection device 7. The crown strip limiting roller 15 can clamp the tail of the crown strip and prevent the tail of the material from colliding with the tail detection device 7, thereby ensuring the accuracy of the tail detection device 7.

[0072] The joint sewing device 14 disclosed in this application is slidably mounted on a bracket and is movable relative to the suction cup assembly 8. The suction cup assembly 8 includes a vacuum device and a suction cup. During operation, the vacuum device of the suction cup assembly 8 is activated, drawing air from the side near the material through the through hole on the suction cup, creating a negative pressure on that side of the suction cup. Under the action of negative pressure, the crown strip is adsorbed, thus fixing the material tail. When the crown strip material head clamping and conveying device conveys the material head to the suction cup, the joint sewing device 14 is activated and moves towards the suction cup assembly 8 until the material head and material tail are clamped. Then, the joint sewing device 14 is activated to sew the material head and material tail together.

[0073] To ensure the stability of the connection between the material tail and the material head after stitching, and to reduce the thickness of the overlap between the material head and tail, a joint rolling roller 9 is also provided between the suction cup assembly 8 and the moving clamping member 10 for rolling the joint portion. The joint rolling roller 9 includes two pressure rollers. When the joint portion is conveyed between the two pressure rollers, the two pressure rollers are activated to press the joint portion tightly. The pressure and start / stop of the pressure rollers can be controlled by a controller to automate the entire process.

[0074] Preferably, a reversing centering roller 13 is provided between the fixing clamp 12 and the feeding device for reversing the crown strip passing through the fixing clamp 12. Through the cooperation of the reversing centering roller 13 and the centering roller, the crown strip is restricted to the desired position, preventing the crown strip from shifting position.

[0075] In addition, this application also discloses a tire processing apparatus, including the crown strip guide automatic feeding device disclosed in the above embodiments. Therefore, the tire processing apparatus with the crown strip guide automatic feeding device also has all the above-mentioned technical effects, which will not be described in detail here.
