A stacker-reclaimer is an automated material handling device that achieves the stacking, storage, and reclaiming of materials through three independent actuators: the stacking head clamp, the stacking operation head, and the reclaiming head. The stacking head clamp operates on the surface of the material, calculating the angle of each control rod based on parameters such as stacking height and swing angle. It then controls the direction and speed of the pneumatic cylinder's movement through small gate switches on the control rods, ensuring precise actions of the stacking head. The stacking operation head is controlled by a microprocessor and can automatically move and rotate at specific time intervals and material quantities to achieve the stacking effect. The reclaiming head allows for rapid sorting and transportation of materials.
A stacker-reclaimer is a common material handling device primarily used to extract bulk materials from a pile and transport them to a designated location. The principle of the stacker-reclaimer is to use mechanisms such as robotic arms or conveyor belts to extract materials from the raw material pile and convey them to the target location. There are two implementation methods: one is the robotic arm type stacker-reclaimer, which uses a motor to drive the robotic arm along a set path to complete the material handling tasks; the other is the conveyor belt type stacker-reclaimer, which transports materials to a designated position via a conveyor belt, completing the material extraction process.
The structure of the stacker-reclaimer mainly includes components such as the robotic arm, support frame, reducer, and transmission chain. The robotic arm is the core part of the entire system, driven by a motor, allowing it to travel along a specific path and grasp materials. The support frame is a structure used to stabilize the robotic arm, usually made of steel, ensuring stability during the arm's movement. The reducer is a device used to adjust the speed of the robotic arm, as high-speed rotation can affect the grasping and placement of materials. The reducer can lower the speed of the robotic arm, thus improving the efficiency of grasping and placing. The transmission chain is an important component that transmits power from the motor to the robotic arm, and its quality directly affects the overall performance of the mechanism.
