In the logistics system, shuttle car has a very wide range of equipment, accompanied by automated logistics and storage warehouse.Shuttle vehicle (RGV) can be easily connected with other logistics systems, such as exit / entry platform, various buffer stations, conveyors, elevators and robots, etc., and transport materials according to plan.In addition, the shuttle car does not need personnel operation and runs fast, which significantly reduces the workload of warehouse management personnel and improves labor productivity. At the same time, the application of shuttle car can make the logistics system very simple.
The control system is the key to the success of RGV.The control requirements of RGV include position control, speed control, loader control and direction control.RGV adopts PLC as controller, which is responsible for motion planning, logic control, various safety protection and communication with upper computer.In motion drive, the inverter with servo drive performance is selected, and the full closed-loop control of position, speed and current is adopted.The walking direction (x direction) adopts the double address recognition mode of photoelectric switch and encoder, and realizes the direction control and position control by calculating the relative position of the target.The operator can operate the RGV manually, semi automatically and automatically through the buttons on the rear operation panel of the car body.
In modern production, the requirements of logistics system are constantly improving, and the technology of logistics is also developing.Transport shuttle vehicle (RGV) makes the whole logistics warehouse system more flexible. It replaces the conveyor and belt system, changes the overall layout of the warehouse, and makes the system more flexible.
