Two-wheel drive monorail conveyor and its cornering control method

Abstract

The invention discloses an over-bending control method of a double-wheel drive single-rail conveyor. The distance between a front wheel and a rear wheel of the single-rail conveyor is larger than the turning radius of a curve; according to the four continuous stages, when the front wheel passes through the curve, the approach speed of the front wheel is first speed kept constant in the first stage and the second stage, the first speed is continued to be reduced to the third speed in the third stage, and the third speed is continued to be increased to the first speed in the fourth stage; the approach speed of the rear wheel is continued to be reduced to the second speed from the first speed in the first stage, the second speed of the rear wheel is continued to be increased to the first speed in the second stage, and the first speed is kept in the third stage and the fourth stage. Compared with the prior art, the speed control over the front wheel and the rear wheel conforms to the actual speed change rule of the front wheel and the rear wheel of the single-rail conveyor, the speed fluctuation caused by mismatching of the actual speed and the output speed is avoided, and it is ensured that the conveyor smoothly and stably runs in the turning process.

Description

technical field [0001] The invention relates to a monorail conveyor, in particular to a double-wheel-driven monorail conveyor with a turning radius smaller than the front and rear track of the monorail conveyor. Background technique [0002] Monorail conveyors are often used in transportation systems such as logistics industry, steel industry, and automobile industry, such as stackers in high-bay warehouses, working machines in wire pickling lines, etc. The conveyor is mainly composed of walking mechanism, lifting mechanism and other components. The walking mechanism runs on a track composed of straight and curved tracks parallel to the ground, and is used to transport unit goods in the conveying system distributed along the track. [0003] The running mechanism of existing monorail transporter has two kinds of single wheel and double wheel. Single-wheel drive conveyors are suitable for systems with small loads or low operating speeds. Large loads or high speeds will cause ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a two-wheel drive monorail conveyor and its cornering control method, which are used to solve the problems in the prior art that the output speed of the motor is inconsistent with the actual running speed of the front and rear wheels, resulting in large speed fluctuations and easy hardware damage.
