technical field

The invention relates to the technical field of AGV trolleys, in particular to an AGV trolley for multi-directional material handling.

Background technique

(Automated Guided Vehicle, AGV for short), also commonly known as AGV trolley, refers to a transport vehicle equipped with electromagnetic or optical automatic navigation devices, capable of driving along a prescribed navigation path, with safety protection and various transfer functions, industrial applications A truck that does not require a driver uses a rechargeable battery as its power source. Generally, its travel path and behavior can be controlled by a computer, or an electromagnetic path-following system can be used to set up its travel path. Affixed to the floor, the unmanned truck relies on the information brought by the electromagnetic track to move and act.

At present, the multi-directional AGV trolleys on the market are mainly flat-plate designs, which have the advantages of large load capacity and multi-directional feeding. However, the trolley has certain defects in the actual operation process: first, because the top of the trolley is a flat plate Design, lack of shielding structure, the center of gravity of the material on the roof will change during the turning process of the trolley, and under the action of inertia, the material can easily fall from the trolley; Since the goods are stacked on the top of the trolley, the overall center of gravity of the trolley will increase. During the turning process, the trolley lacks a structure to adjust the center of gravity, which is prone to overturning. At present, many manufacturers reduce the speed of the trolley while driving. To avoid the above problems, but this method will reduce the transport efficiency of the car, so there are certain drawbacks.

Based on this, the present invention designs an AGV trolley for multi-directional material handling to solve the above problems.
