Embodiment Construction

[0039]Embodiments of the present invention are described below with reference to the accompanying drawings.

[0040] Figure 1-3 The overall structure of the automatic guided vehicle (AGV) shown is similar to the vehicle structure disclosed in Japanese Patent No. 3013716, and will now be briefly described.

[0041] The AGV comprises a drive / steering unit 3 of the magnetically guided type, which has a drive unit 5 for driving wheels 6, and a steering unit 4 for driving wheels 6, and a trolley with a chassis 16 with wheels at the corners 12. The drive is controlled by a control device 8 which processes signals from a magnetic sensor 7 which detects the magnetism produced by the guide path formed by the magnetic tape 10 . The steering / drive unit 3 is attached under the chassis. Such as image 3 As shown, the magnetic sensor 7 is attached to the front of the support of the driving wheel 6 with a bracket 17 so that the magnetic sensor 7 rotates together with the driving wheel 6 ...

Abstract

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-searth 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.

Description

field of invention [0001] The present invention relates to a method for automatically guiding the operation of an unmanned vehicle, which is guided by a guiding path preset on the ground in factories, warehouses, etc., and loads and handles various loads in a fully automatic manner; more specifically It relates to an automatic guidance method with a route search function and an anti-deviation function, so that a vehicle that is placed in an operation start position and whose magnetic sensor deviates from the guidance path within a certain limit, or suddenly deviates from the route due to some reasons during normal operation The car is restored to the guided path by searching and finding the tape. Background technique [0002] Various automated guided vehicles (often abbreviated as AGVs) have been developed and used in practice. [0003] For example, Japanese Registered Patent No. 3013716 discloses an unmanned magnetically guided vehicle that runs automatically along a close...
