How To Achieve High-Speed Operation Of RGV?
RGV is an automated handling equipment that runs on a fixed track. To achieve high-speed operation of RGV, design and optimization can be carried out from the following aspects:
Drive System Optimization
1. Motor selection:
Select high-performance motors, such as AC variable frequency motors, to improve operating efficiency and response speed. Select the appropriate motor power and speed according to actual needs to ensure that the trolley can maintain stability and reliability when running at high speed.
2. Drive mode:
Advanced drive technology, such as direct connection between the reducer and the wheel, is used to convert the rotational motion of the motor into the linear motion of the wheel. In some special cases, multiple motors can be used to drive different wheels separately to achieve more flexible steering and driving control.
Control System Optimization
1. Parametric control design:
The parametric control design is used to facilitate the adjustment of the position, speed, accuracy and other factors of the trolley to achieve high-speed operation. The movement of the trolley is precisely controlled through the preset program and the received signal.
2. Positioning and navigation:
Use on-board sensors, laser guidance systems or magnetic strip guidance systems to achieve accurate identification and positioning of the running track. The positioning signal is obtained by barcode recognition or laser ranging, and compared with the current position, and then the inverter is controlled to realize the start and stop of the motor.
3. Communication and scheduling:
The control system of RGV can communicate with the host computer or WMS (warehouse management system), receive task instructions and feedback the operating status. In automatic mode, the shuttle dispatching system decomposes the task to each shuttle through wireless communication to achieve multi-point automatic operation and efficient scheduling.
Other Factors
1. Track design:
Choose appropriate track material and form (such as aluminum straight track or curved track) to ensure the flatness and stability of the track. Optimize the layout and connection method of the track to reduce the resistance and vibration of the trolley during driving.
2. Maintenance:
Perform regular maintenance on RGV, check the operating status of the motor, the flatness and connection of the track, etc., to ensure that the trolley runs in the best condition.
3. Safety protection:
Equipped with complete safety protection devices and emergency stop buttons, etc., to ensure that the trolley can detect and handle abnormal situations in time when running at high speed.
In general, high-speed operation of RGV can be achieved by optimizing the drive system, control system, track design, and strengthening maintenance and safety protection. At the same time, customized design and optimization are also required according to actual application scenarios and needs to meet the handling needs of different companies.
