The automatic guide method for vehicles relates to an automatic guide method for the operation of unmanned vehicles which, guided along guide paths preset on the floor in factories and warehouses, etc., carry and handle various loads in a fully automated fashion, and more particularly to an automatic guide method which has a course-search function and function to prevent straying such that a vehicle which is positioned at the start of an operation with its magnetic sensor off the guide path within certain limits or which strays off course abruptly for some reason during ordinary operation, is restored to the guide path by searching and finding the magnetic tape.

Automatic guide method for vehicles

A magnetically guided unmanned vehicle system to carry various loads along a guide path of a closed loop which comprises guide path consists of magnetic tape, a magnetic guide type steering drive unit having a magnetic sensor to detect magnetism from said tape and a drive wheel, said steering drive unit having a driving means to drive said drive wheel and a steering means controlled automatically by signals detected by said magnetic sensor, a trolley which has wheels at each of the four corners of the lower surface of a chassis thereof, the front said wheels having a universal casters, and a carriage shelf assembly which has one or a plurality of horizontal automatic roller conveyer(s) as shelves. The magnetically guided vehicle can be constructed by combining the trolley, the steering drive unit and the carriage shelf assembly and the trolley can be used for its original purposes by disassembling such parts. The drive wheel can be changed from a position wherein the wheel touches the floor with a pressure sufficient for running to a position wherein the wheel is suspended with a clearance above the floor.
