[0003] During the tire production process, the tire embryo needs to be moved from one device to another for operation. During this movement, the tire embryo needs to be flipped due to the operation of the two devices. However, most of the current flipping equipment requires manual intervention and does not achieve a high degree of automation. The flipping equipment needs to clamp the tire during the flipping process to prevent it from shaking. However, today's clamping equipment usually clamps the surface of the tire directly, and harder parts will damage the tire, resulting in unqualified products.

[0004] For example, Chinese patent application number CN 114406939 B: A tire assembly flip clamping mechanism for automobile production line, disclosed including a conveyor frame, a tire flip plate is rotatably connected between two inner opposite surfaces at one end of the conveyor frame; a movable clamping plate is slidably matched with the surface of one end of the flip frame; two inner side surfaces at one end of the conveyor frame are rotatably connected with a take-up drum that meshes with the tire flip plate; the take-up drum is connected to the movable clamping plate through a pull line; a movable guide frame that meshes with two tire flip plates is sleeved on the lower surface of the conveyor frame; a telescopic cylinder is fixed on the lower surface of the conveyor frame; the end of the piston rod of the telescopic cylinder is fixedly connected to the movable guide frame.

[0025] The transport device includes a transport frame 10 and a transport hanging shaft 12. The transport hanging shaft 12 is installed at the end of the transport frame 10. The transport hanging shaft 12 is perpendicular to the transport frame 10 and its direction is consistent with its walking direction. The transport frame 10 is also equipped with a transport motor 13 and an adjustment motor 14. The motor gear of the transport motor 13 is engaged with the transport walking frame 11, which can drive the transport frame 10 to walk on the transport walking frame 11. The motor gear of the adjustment motor 14 can drive the transport hanging shaft 12 to move up and down, which is used to adjust the position of the transport hanging shaft 12 so that it can adapt to the transportation of tires of different models, and the tires can be placed vertically on it through the transport hanging shaft 12.

[0026] A turning method of an inner buckle type tire blank turning mechanism of the present invention comprises the following steps: S1: The transport device removes the tire blank from other equipment in the workshop and places it on the transport hanging shaft 12, and then moves the tire blank to the top of the turning device; S2: The turning motor 34 of the turning device drives the transport motor 13 to rotate upward, and the placement table 35 gradually contacts and pushes the tire green sheet, and the notch passes over the transport hanging shaft 12, and the tire green sheet is taken off the transport hanging shaft 12 and supported on the placement table 35 by the auxiliary plate 36. At the same time, the transport device also returns synchronously, and then the placement table bracket 31 rotates to 60°-85°, and the tire green sheet is completely separated from the transport hanging shaft 12, and the placement table bracket 31 rotates in the opposite direction to be flat; S3: At this time, the clamping hydraulic cylinder 50 of the clamping assembly is started, pushing the clamping connecting rod 51 to make the outermost ends of the clamping blocks 54 on both sides rotate inward at the same time, limiting the tire blank at the center position; S4: The grabbing device is started and moved to the top of the tire blank, then the grabbing plate 20 is moved downward, the grabbing hand 22 is inserted into the tire blank, and then expanded outward to grab the tire, and then the tire is moved upward together; S5: The grabbing device moves back to the top of the conveyor belt 42 of the fixed plate 40, retracts the grabbing buckle 22, and then the tire can be placed on the tire tray 41. At this time, the tire blank can be transported to the next equipment in the workshop along the conveyor belt 42.

[0027] Working principle: at the beginning of operation, the transport hanging shaft 12 on the transport frame 10 removes the tire from the previous equipment, and then the transport motor 13 is started to make the transport device move horizontally with the tire. However, when the transport frame 10 moves to the top of the flipping device of the placement table 35, the transport frame 10 can touch the travel switch, and the transport frame 10 can return at this time, and the flipping motor 34 is started at the same time, and the placement table rotating shaft 32 drives the placement table bracket 31 to rotate upward, so that the placement table 35 abuts against the tire and pushes the tire. Under the movement of the return of the transport frame 10 and the restriction of the placement table 35, the tire will be removed from the transport hanging shaft 12 and fall on the placement table 35. The tire is prevented from falling by the support of the auxiliary plate 36. When the placement table bracket 31 rotates to the maximum angle of 85°, the flipping motor 34 can be automatically started to rotate in the opposite direction, so that the placement table bracket 31 is gradually flattened, and the removal and flipping of the tire are completed.

[0028] When the placement table bracket 31 is completely flat, the clamping hydraulic cylinder 50 can be started by controlling the contact switch, and the clamping connecting rod 51 can be pushed to rotate by the hydraulic rod. At this time, the two clamping shafts 52 can be rotated at the same time by pulling the clamping connecting rod 51, and the rotating clamping shafts 52 can drive the mutually meshing clamping blocks 54 to clamp inward synchronously. During the clamping process, the tire will also be pushed to the center, which is convenient for the next step.

[0029] After the clamping block 54 is clamped, one of the grabbing motors 24 can be started to drive the grabbing device to move. When it moves to the top of the flipping device and touches the travel switch, it can stop moving. At the same time, the other grabbing motor 24 is started to move the grabbing plate 20 downward, and the grabbing buckle hand 22 is gradually extended into the tire. Then the grabbing plate 20 can stop moving, and the grabbing hand hydraulic cylinder 25 on the grabbing plate 20 is started to drive the grabbing buckle hand 22 to expand outward. The clamping hydraulic cylinder 50 is started to drive the clamping block 54 to loosen the tire, and the clamping block 54 is gradually reset. While the grabbing buckle hand 22 is expanded, the grabbing plate 20 will move upward until it touches the travel switch. One of the grabbing motors 24 can be started to make the grabbing device return. When it returns to the top of the conveyor belt 42, the grabbing buckle hand 22 can be retracted inward, thereby loosening the tire, so that the tire falls on the tire tray 41, and then is transmitted to the next device through the conveyor belt 42. At this time, the entire process of tire transportation, picking up, flipping, grabbing, and transmission can be completed. When the next tire needs to be flipped, the above process can be repeated.

[0030] In summary, the inward-locking tire embryo flipping mechanism does not require manual intervention throughout the entire process and has a high degree of automation. The auxiliary plate 36 can also support the outer periphery of the tire to prevent the tire from slipping when the placement table 35 rotates. The notch and the concave disc setting of the placement table 35 can fit various types of tires. At the same time, the notch setting can also facilitate the removal of the tire from the transport hanging shaft 12; through the setting of the clamping assembly, the four clamping blocks 54 can move inward at the same time to push the tire to the center, which is convenient for the subsequent grasping device to position and grasp, and the clamping block 54 can also clamp the tire to effectively prevent the tire from shaking; the rubber roller clamping can effectively prevent damage to the tire, and the roller can rotate during the process of the clamping block 54 clamping the tire, which greatly reduces the friction between the clamping block 54 and the tire during the clamping process, further preventing damage to the surface of the tire embryo.
