Description

Technical Field

[0001] The present invention relates to the technical field of roller line conveying, and in particular to a conveying system and method of a three-in-one roller line. Background Art

[0002] The roller conveyor line is suitable for conveying items with a flat bottom. It is mainly composed of a transmission roller, a frame, a bracket, a driving device and other parts. It has the characteristics of large conveying capacity, fast speed, light operation, and can realize the co-linear diversion conveying of multiple varieties. The roller conveyor is suitable for conveying various boxes, bags, pallets and other pieces of goods. Bulk materials, small items or irregular items need to be placed on pallets or in turnover boxes for transportation. It can convey single-piece materials with very large weight or withstand large impact loads. The roller lines are easy to connect and filter, and multiple roller lines and other conveyors or special machines can be used to form a complex logistics conveying system.

[0003] Roller conveyor lines are generally used in object detection, diversion, packaging and other systems. They are roughly divided into powered rollers, unpowered rollers, electric rollers and stacking rollers. The line forms are divided into: straight roller lines, curved lines, sloped lines, telescopic lines and multi-fork lines, etc. The conveying speed of the roller has two types: fixed speed and adjustable speed. The adjustable speed can be divided into: electronic adjustable speed, variable frequency adjustable speed and mechanical adjustable speed.
