[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-3 As shown, it includes a gantry frame and a transport device, a turning device and a conveying device installed on the gantry frame. The turning device is located between the transport device and the conveying device. The conveying device, the transport device and the turning device are all controlled by a travel switch to start, stop, reciprocate, rotate, etc., and the label on the tire is detected by a conventional detection device. The detection result controls whether the turning motor 24 needs to be started to rotate forward or reverse.

[0024] The flipping device includes a flip bracket 20, a flip mounting frame 22, a flip assembly and a clamping claw, wherein the flip mounting frame 22 moves on the flip bracket 20 through a slider 29, the flip mounting frame 22 is provided with two and symmetrically arranged, the clamping claw is installed on the flip assembly, the flip assembly is slidably connected to the flip mounting frame 22, and an auxiliary limit block 32 is also installed on the clamping claw, the flip assembly includes a slide plate 26 and an electric cylinder 28, wherein the electric cylinder 28 is fixed between the flip mounting frames 22, the telescopic rod in the electric cylinder 28 is fixed on the slide plate 26, a cross bar is fixed in the middle of the flip mounting frame 22, one side end face of the electric cylinder 28 is fixed on the cross bar, the slide plate 26 slides on the flip mounting frame 22, and a flip motor 24 is fixed on one side end face of the slide plate 26, which can drive the flip motor 24 and the clamping claw on the slide plate 26 through the electric cylinder 28. The claws move together to adjust the height of the clamping claws so that they can adapt to the height of the tire when the transport device transports the tire. The flip motor 24 controls the flipping of the clamping claws. The clamping claws include a clamping arm 23 and a protective roller 27. The clamping arm 23 is arranged in an arc shape and is rotatably mounted on the side of the slide plate 26 away from the flip motor 24. It is also connected to the flip motor 24. The protective rollers 27 are movably mounted on the two end portions of the clamping arm 23. The material of the protective rollers 27 is one of resin and rubber. The resin is relatively soft and has a large friction force. Without damaging the tire, the tire will be clamped more firmly and not easy to fall off. At the same time, the rotatable protective rollers 27 can change the sliding friction of the clamping claws during the clamping process into rolling friction, which greatly reduces the friction force on the tire and effectively reduces the damage to the tire.

[0025] The auxiliary limit block 32 is installed at the protection roller 27. The auxiliary limit block 32 is internally provided with a counterweight block 33 and two symmetrically provided auxiliary limit claws 34. The two sides of the counterweight block 33 are provided with arc surfaces. One side of the auxiliary limit claw 34 is provided with an arc surface and the other side is provided with an inclined surface. The arc surface setting makes it difficult for the counterweight block 33 and the auxiliary limit claw 34 to get stuck when they abut against each other. The auxiliary limit block 32 is internally provided with a counterweight block slot 39 and a limit claw sliding slot. The limiting claw slide 38 is at the two feet, and the auxiliary limiting claw 34 slides in the limiting claw slide 38. The two side end surfaces of the limiting claw slide 38 are also provided with inner grooves 37. The two side end surfaces of the auxiliary limiting claw 34 extend into the inner groove 37, and the limiting claw spring 35 is fixed between the inner wall of the inner groove 37. The auxiliary limiting block 32 is passed through the two sides of the counterweight slide 39, and the counterweight 33 slides in the counterweight slide 39. The counterweight slide 39 is connected to the auxiliary limiting block 32. The overweight block spring 36 is installed on the inner wall of the counterweight block slide groove 39, and the counterweight weight of the counterweight block 33 is much greater than the elastic force of the counterweight block spring 36. Through the setting of the auxiliary limiting claw 34 and the counterweight block 33, when the clamping arm 23 flips the tire, the counterweight block 33 can stretch or compress the counterweight block spring 36 due to its own weight and slide outward. The sliding of the counterweight block 33 will push the auxiliary limiting claw 34 to slide in the limiting claw slide groove 38 through the setting of the arc surface. The sliding of the auxiliary limiting claw 34 will compress the limiting claw spring 35 and extend outward, and the extended auxiliary limiting claw 34 will abut against the side surface of the tire, effectively preventing the tire from falling due to vibration generated during the transportation of the tire on the clamping claw. At the same time, during clamping, since the auxiliary limiting claw 34 is inside the auxiliary limiting block 32, when the tire position is not correct or offset occurs, the auxiliary limiting claw 34 in clamping will not abut against the tire, causing tire damage.

[0026] The turning bracket 20 is fixedly mounted with a clamping motor 25 and a turning travel motor 30, wherein the turning travel motor 30 is connected to the gantry to control the turning device to travel on the gantry. The turning bracket 20 is internally rotated and connected with a screw 31, and the clamping motor 25 and the screw 31 are connected by a belt. The slider 29 is mounted on the screw 31 and is threadedly connected to the screw 31. The thread on the screw 31 is divided into two parts, and the two threads are in opposite directions, controlling the slider 29 to move synchronously in opposite directions. The thread on the screw 31 can enable the turning mounting frames 22 on both sides to move inward at the same time to complete the clamping action, and the two move at the same speed, which can enable them to keep the tire in the center, facilitating positioning of the next process, and through the arrangement of the electric cylinder 28, the turning motor 24 and the clamping motor 25, the entire turning device has a high degree of automation, no manual intervention is required, and it can operate quickly and continuously.

[0027] The gantry frame includes a transport frame 11 and a flip frame 21. The flip bracket 20 is installed on the flip frame 21 and walks on it. The transport device is installed on the transport frame 11 and walks on it. The transport device includes a transport frame 10 that walks on the transport frame 11. The top of the transport frame 10 is fixedly installed with an adjusting motor 13 and a transport motor 14. The bottom of the transport frame 10 is installed with a transport hanging shaft 12. The transport hanging shaft 12 is controlled by the adjusting motor 13 to move up and down so that tires of different models can be transported. The transport motor 14 controls the transport frame 10 to move on the transport frame 11. The conveying device includes a conveyor belt 40. Several placing platforms are arranged on the conveyor belt 40. The placing platforms are concave in shape and move synchronously with the conveyor belt 40. The position of the placing platforms is exactly at the maximum position of the flipping device moving away from the transport device.

[0028] Working principle: at the beginning of operation, the transport hanging shaft 12 on the transport frame 10 removes the tire from the previous device, and then the transport motor 14 is used to move the transport device horizontally with the tire. When the transport frame 10 moves between the two clamping arms 23, the transport frame 10 can touch the travel switch, and the clamping motor 25 can be started at this time. The clamping motor 25 drives the lead screw 31 to rotate through the belt, and the rotation of the lead screw 31 can make the sliders 29 on both sides move inward at the same time, so that the flip mounting frame 22 drives the clamping claws to move inward and clamp the tire. After clamping the tire, the flipping travel motor 30 and the flipping motor 24 can be started at the same time. While the flipping travel motor 30 drives the tire to move, the flipping motor 24 drives the clamping arm 23 to flip the tire. The tire can be flipped during the movement of the flipping device, which greatly saves the time required for tire flipping transportation and effectively increases the tire operation efficiency.

[0029] When the tire is flipped to a horizontal position, the counterweight 33 in the auxiliary limit block 32 will stretch or compress the counterweight spring 36 due to its own weight, causing the counterweight 33 to slide by squeezing the auxiliary limit claw 34 through the arc surface. When the counterweight 33 completely passes over the auxiliary limit claw 34, its flat surface will abut against the auxiliary limit claw 34, thereby clamping the auxiliary limit claw 34 to prevent the auxiliary limit claw 34 from resetting. The auxiliary limit claw 34 is pushed out of the auxiliary limit block 32 under the pressure of the counterweight 33, so that it is partially exposed and stuck on the side surface of the tire, thereby preventing the tire from falling due to vibration generated during the transportation of the tire on the clamping claw.

[0030] During the process of flipping the travel motor 30 to drive the flipping device to move, the clamping arm 23 drives the tire to gradually rotate to a horizontal level, and the label on it follows the need to face up or down. When the flipping bracket 20 moves to just above the placement table, it can stop moving, and the clamping motor 25 rotates in the opposite direction to make the clamping claw release the tire, and the tire can fall on the placement table and then be conveyed to the next device through the conveyor belt 40. At the same time, the flipping travel motor 30 also drives the flipping device to return. At this time, the entire process of transporting, grabbing, flipping and conveying the tire can be completed. When the next tire needs to be flipped, the above process can be repeated.

[0031] Moreover, when the tire transportation is completed, the clamping arm 23 is in a vertical state again. At this time, the auxiliary limit block 32 is in a horizontal state, and the counterweight block 33 is not affected by gravity. Under the elastic force of the counterweight block spring 36, the counterweight block 33 is pulled back into the auxiliary limit block 32. Then the counterweight block 33 no longer restricts the auxiliary limit claw 34, and the auxiliary limit claw 34 will also be retracted into the auxiliary limit block 32 under the elastic force of the limit claw spring 35.

[0032] In summary, the tire embryo bidirectional flipping member, through the setting of the auxiliary limiting claw 34 and the counterweight block 33, can make the auxiliary limiting claw 34 extend outward and abut against the side surface of the tire when the clamping arm 23 flips the tire, effectively avoiding the phenomenon of the tire falling due to vibration generated during the transportation of the tire on the clamping claw. At the same time, since the auxiliary limiting claw 34 is inside the auxiliary limiting block 32, when the tire position is not correct and there is an offset, the auxiliary limiting claw 34 will not abut against the tire during the clamping process, causing tire damage; the electric cylinder 28 can drive the flip motor 24 and the clamping claw on the slide 26 to move together, so as to adjust the height of the clamping claw so that it can adapt to the transport wheel of the transport device. The height of the tire can be adjusted according to the situation of the tire being overturned; the tire will be clamped more firmly without damaging it and will not fall off easily. At the same time, the rotatable protective roller 27 can change the sliding friction of the clamping claws during the clamping process into rolling friction, which greatly reduces the friction force on the tire and effectively reduces the damage to the tire. Moreover, through the arrangement of the electric cylinder 28, the turning motor 24 and the clamping motor 25, the entire turning device has a high degree of automation, no manual intervention is required, and it can operate quickly and continuously. At the same time, the tire can be turned over during the movement of the turning device, which greatly saves the time required for tire turning and transportation and effectively increases the operating efficiency of the tire.
