Technical Field

[0001] The utility model relates to the technical field of cargo transportation, in particular to an automatic tire destacking mechanism. Background Art

[0002] In the automobile manufacturing industry, tires are transported to the final assembly workshop in the form of stacks. In order to improve unloading efficiency, destacking machines are usually used to destacker the tires and transfer them to roller conveyor lines to meet the needs of large-scale tire assembly in the final assembly workshop.

[0003] However, the existing destacking equipment mostly uses mechanical arms for destacking, which has low efficiency, complex structure and high maintenance cost. The sizes and patterns of tires of different models are different, and the tire surfaces are provided with different degrees of concave and convex patterns. In addition, the tires are round in shape. During the operation of the mechanical clamp, if the destacking gripper cannot fit the outer surface of the tire, the tire may fall during the clamping process, requiring repeated clamping, which wastes a lot of production time and is not conducive to the work efficiency of tire destacking.

A driving motor 19 is provided at one end of the connecting frame 16.

[0024] See also Figure 3The rotating mechanism 8 includes a sliding block 801, the top of the sliding block 801 is fixedly connected to a sleeve 802, the inside of the sleeve 802 is rotatably connected to a connecting rod 804, the outer side of the connecting rod 804 is rotatably connected to a shaft seat 803, and the outer side of the shaft seat 803 is fixedly connected to the side wall of the splint 12, so that the splint 12 can rotate around the connecting rod 804.

[0025] See also Figure 1-Figure 5 Four groups of second springs 11 are provided, and the outer ends of the four groups of second springs 11 are fixedly connected to the inner side of the movable plate 10. The four groups of springs can provide elastic force for the clamping plate 12.

[0027] See also Figure 1-Figure 5 A non-slip rubber 13 is provided on one side of the clamping plate 12 close to the conveying shaft 17, which can increase the friction between the clamping plate 12 and the tire when clamping, and prevent the tire stack from relative displacement.

[0028] Working principle: Figure 1-Figure 5 As shown, when in use, the tire stack is placed on the conveying shaft 17, the hydraulic lift 1 is started, the support plate 2 is raised, the end of the support frame 6 is lifted to the gap between the top tire and the second tire, the telescopic cylinder 3 is started, and the telescopic rod of the telescopic cylinder 3 will push the fixed plate 5 to move toward the conveying shaft 17. Synchronously, the ends of the support frames 6 on both sides of the conveying line will be inserted into the gap between the tire stacks. The telescopic cylinder 3 continues to push the fixed plate 5. Since one end of the support frame 6 close to the conveying shaft 17 is set in an inclined plate shape, it is convenient to insert it between the two tire gaps. Therefore, the tire stack will move to the middle of the support frame 6 through the slope on the support frame 6. Synchronously, due to the obstruction of the tire stack, the sliding block 801 will move along the slide groove 7 toward the fixed plate 5. The tire moves in the direction of rotation. Since the outer side of the tire is circular, the tire and the clamping plate 12 are squeezed, which will make the clamping plate 12 follow the outer circle rotation direction of the tire. The clamping plate 12 rotates with the connecting rod 804 as the circular axis, so that the side walls of the two groups of clamping plates 12 are more closely attached to the outer surface of the tire. When the support frames 6 located on both sides of the conveying shaft 17 move toward the middle and contact the center of the conveying shaft 17, the telescopic cylinder 3 stops running, and the hydraulic lift 1 starts again to lift the tire stack on the top layer upward, and the conveying shaft 17 moves the remaining tire stacks forward, and the removed tires are placed at the rear end of the conveying shaft 17 and transmitted to the assembly area, leaving a tire on the transmission line, and the drive motor 19 is started, and the conveying shaft 17 moves backward to transport the tire stack to remove the next tire.
