Halved belt sorting trolley with liftable conveying surface, halved belt sorting system and sorting method thereof

Abstract

The invention discloses a halved belt sorting trolley with a liftable conveying surface, a halved belt sorting system and a sorting method thereof. The sorting trolley comprises a chassis, wherein a storage box is arranged on the chassis; a first chain and a second chain which are opposite are rolled in the storage box; the first chain and the second chain are driven by a motor to extend and retract; mutually separated parts of the first chain and the second chain are flexible; mutually engaged parts of the first chain and the second chain define a rigid rod body; the rigid rod body extends tothe outer part of the storage box, and is connected to the bottom of a conveyor; and the conveyor is arranged on a limiting mechanism. The halved belt sorting trolley adopts a special chain, can realize switching needs of a conveying surface of the conveyor at different heights by regulating length of the rigid rod body extending to the outside of the storage box, and creates beneficial conditions for multi-layer grid hole sorting, so that occupied longitudinal space can be effectively reduced by rolling the chains into the storage box under a normal state; and meanwhile, lifting height of the halved belt sorting trolley can be reasonably regulated according to different application occasions.

Description

technical field [0001] The invention relates to the field of logistics sorting, in particular to a cross-belt sorting trolley with a liftable conveying surface, a cross-belt sorting system and a sorting method thereof. Background technique [0002] The cross-belt sorting system is assembled by the main drive belt conveyor and the trolley (referred to as "cart") carrying a small belt conveyor. When the "cart" moves to the specified sorting position, it will rotate The belt completes the task of sorting and sending out the goods. Because the main drive belt conveyor and the belt conveyor on the "trolley" are in a cross shape, it is called a cross belt. [0003] The traditional cross-belt is a tiled single-layer structure, which drives each trolley to move through the chain drive structure. For conventional sorting trolleys, such as the cross-belt logistics sorting trolley disclosed in the application number 201810494383.0, the belt conveyor on it The position is fixed and ca...

Problems solved by technology

[0003] The traditional cross-belt is a tiled single-layer structure, which drives each trolley to move through the chain drive structure. For conventional sorting trolleys, such as the cross-belt logistics sorting trolley disclosed in the application number 201810494383.0, the belt conveyor on it The position is fixed and cannot be lifted, so it needs to be used in conjunction with a single-layer sorting grid, which cannot meet the sorting needs of thin parts such as medicine, clothing, tobacco, banks, and multiple customers, that is, it cannot meet the multi-layer grid. Or the use of multi-layer shelves needs
