In factories, warehouses, and other places, material handling transfer bogie with flexible and efficient advantages has gradually become the main force of material transportation. There is no track binding, but also in a small space, accurate steering, and flexible positioning. How exactly to do it?
The realization of accurate steering can not be separated from the collaboration of various types of sensors. Gyroscope sensor is like material handling transfer bogie “balance monitor”, real-time perception of material transfer bogie’s attitude changes, once there is a tilt or angle deviation, it will immediately feed back to the control system to avoid the steering process occurring during the rollover.
The encoder is responsible for measuring the rotation speed and rotation angle of the wheels, providing the control system with key data such as transfer bogie traveling distance and steering amplitude, just like installing a “ruler” for material transfer bogie, so that every steering has an accurate basis.
The control system is called the “intelligent center” of material handling transfer bogie, which receives the data from the sensors, combines the preset driving path and instructions, and sends out accurate control signals to the drive system after complex arithmetic. Take the common multi-wheel independent drive transfer bogie as an example, each wheel is equipped with an independent motor, and the control system can flexibly adjust the speed and steering angle of each wheel.
When turning, by controlling the inner wheels to decelerate or even reverse, and the outer wheels to maintain normal speed, the differential steering principle is utilized to realize small radius turning, which makes it easy to steer even in narrow passages.
Navigation technology likewise plays an important role in precision steering. Laser navigation is one of the most widely used technologies at present. By emitting laser beams to scan the reflective plates in the surrounding environment, transfer cart on wheels can construct real-time maps to determine its own position and traveling direction. This way, transfer cart on wheels has the ability of “environmental awareness”, even in the face of a complex operating environment, can also plan the path, complete the precise steering.
In addition, magnetic navigation, visual navigation and other technologies also have their own advantages: magnetic navigation through the magnetic strips laid on the ground to guide the driving, high stability; visual navigation with the help of the camera to collect images, combined with AI algorithms to identify the environment information, to achieve autonomous steering.
In addition to hardware and technology, the optimization of software algorithms is also crucial. Advanced control algorithms can quickly process and analyze sensor data and adjust steering strategies according to different working conditions. For example, in the case of heavy loads, it is calculated to increase the steering effort automatically; when approaching the target position, it adopts a finer control to realize millimeter-level stopping accuracy.
The precise steering of transfer cart on wheels is the result of the synergistic cooperation of sensors, control systems, drive systems, navigation technology, and software algorithms. The continuous innovation and progress of these technologies make the handling performance of material handling transfer bogie more and more outstanding, bringing higher efficiency and flexibility for industrial production and logistics transportation.
