During the production process, tires are often handled and stacked by stacking machines to complete the transportation process of tires.

[0003] The stacking machine is mainly composed of a manipulator and a gripper. During handling and stacking, the tires are transported to the vicinity of the stacking machine by the conveyor belt, then the stacking machine moves above the tire by the manipulator, the tire surface is adsorbed by the gripper, the tire is fixed, then the tire is moved to the designated position by the manipulator, and is stacked layer by layer to complete the stacking.

[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] The palletizer mainly consists of a robotic arm and grippers. During the handling and palletizing process, the tires are transported to the vicinity of the palletizer via a conveyor belt. The palletizer then performs initial positioning using a mechanical vision system mounted on it, causing the robotic arm to move above the tires. The grippers then adhere to the tire surface to fix the tires in place. The robotic arm then moves the tires to the designated position and stacks them layer by layer to complete the palletizing process.

[0044] However, since the tire still has multiple specifications under the same diameter, the tire specifications are more, so that when the tires of different specifications are fixed and stacked, the grabbing is unstable, and then the tire shakes during transportation and placement, thereby affecting the stability of the tire during stacking, and the stacking is not neat or the stacking collapses;

[0045] When the diameter of the tire circle of the tire increases while the outer diameter of the tire is constant, the diameter of the hub required by the tire increases, according to the formula: tire diameter=hub diameter+(section width*flat ratio)*2, therefore, when the hub diameter increases, in order to ensure that the tire diameter does not change, the section width of the tire needs to be reduced at this time, therefore, when the tire diameter is fixed, the section width of the tire decreases when the diameter of the tire circle increases, that is, the distance between the upper end surface and the lower end surface of the tire decreases.
