1.2 Structure and working principle
The circular shuttle is mainly composed of rail, car body, walking wheel, walking motor, walking wheel guide mechanism, conveyor, conveyor motor, universal wheel, sliding contact power supply system, polyurethane buffer and control system. The minimum turning radius of the circular track is R500, and the sides of the outer track are the guide surfaces. Two walking wheels are installed on the car body, and the walking motor is installed on the side of the walking wheel, which is directly driven. Two walking wheels with rotating mechanism and front and back with guide mechanism, four guide wheels are hugged on both sides of a track to ensure that the walking wheel can walk freely according to the designed curve. The other wheel is a universal wheel, without guide, and runs directly on the inner track plane. The conveyor is installed on the car body and docks with the input and output platforms around it. The control system adopts sliding contact power supply and bar code positioning. The distance detection sensors and mechanical polyurethane buffers are installed at both ends of the car body to ensure the safety of the ring shuttle.

Conclusion
The circular shuttle car is developed from a reciprocating shuttle car. On the same circular track, there can be multiple shuttle cars running at the same time, making up for the shortcomings of the insufficient transport capacity of the reciprocating shuttle car. When the running route is not on a straight line, the transportation of goods needs to be sorted, and there are many platforms, a monorail ring shuttle is generally used for the overall layout of the system. However, with the increase in the number of shuttles, the difficulty of the dispatching system has also greatly increased, and the traffic jams of the vehicles will be very serious, but will cause the capacity of the entire system to decline.
