AGV trackless trolley drive wheel automatic correction device

Abstract

The invention discloses an automatic correction device for driving wheels of an AGV trackless trolley, which comprises a trolley and a magnetic strip. Sensor, left driving wheel, left driver, two universal wheels and two road wheels, the programmable logic controller PLC is housed in the described on-board controller, it is characterized in that: also comprise driving gear, driven gear, rotating shaft I , the rotating shaft II and the angle correction potentiometer, the rotating shaft I and the rotating shaft II are mounted on the car body, and the rotating shaft I is installed in the middle position between the left driving wheel and the right driving wheel, and the driving gear is fixedly mounted on the driving inside the assembly housing. The invention has a novel structure, can realize automatic centering of the navigation sensor, automatic alignment and alignment between the driving wheel and the magnetic strip, simple program control, stable operation, safety and reliability, and long service life.

Description

technical field [0001] The invention relates to a conveying machine, in particular to an automatic correction device for driving wheels of an AGV trackless trolley. Background technique [0002] AGV (Automated Guided Vehicle, referred to as AGV) trackless trolley refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed guiding path, with safety protection and various transfer functions, often used in logistics In the transportation operation of storage. Most of the existing AGV trackless cars use navigation sensors and magnetic strips to navigate, and the drive assembly adopts a swingable differential speed control method. When this type of AGV trackless car is derailed or repaired and put back online, the operator must first push the AGV For trackless cars, the center of the navigation sensor of the AGV trackless car is directly above the magnetic strip, and the center line between the ...

Problems solved by technology

Most of the existing AGV trackless cars use navigation sensors and magnetic strips to navigate, and the drive assembly adopts a swingable differential speed control method. When this type of AGV trackless car is derailed or repaired and put back online, the operator must first push the AGV For trackless cars, the center of the navigation sensor of the AGV trackless car is directly above the magnetic strip, and the center line between the left and right driving wheels of the AGV trackless car should basically coincide with the center line of the magnetic strip, so that the AGV trackless car can start And run along the magnetic strip trace, otherwise, the AGV trackless trolley may start out of order and disorderly, because the installation position of this form of drive assembly is relatively hidden, and the center line between the left and right drive wheels can be freely Swing, in this way, when manually correcting the AGV trackless trolley, the operation is more difficult
