Double-layer vertical conveyor, double-layer sorting system and sorting method thereof

Abstract

The invention discloses a double-layer vertical conveyor, a double-layer sorting system and a sorting method thereof. The double-layer vertical conveyor comprises a first annular rail and a second annular rail which are consistent in shape and area, wherein axes of the first rail and the second rail are parallel to a horizontal plane, and the axes of the first rail and the second rail are equallyin height and are arranged at an interval; at least one loading device is arranged on each of the first rail and the second rail and can move along the first rail and the second rail, and the upper surface of the loading device is kept in an upward state during moving. According to the abovementioned scheme, the double-layer vertical conveyor has the advantages that two rails which are not coaxialto each other are adopted; single-point connection and the position of a connection point of the loading device and a moving part in the rails are designed, so that the surface of the loading deviceis kept in an upward state all the time, and an object on the loading device cannot fall off in the whole moving process; a turning area and the loading device in a lower layer rail area can be fullyutilized to realize sorting, so that the sorting efficiency is improved; and meanwhile, the arrangement flexibility of a feeding line, a sorting port and other equipment can be improved.

Description

technical field [0001] The invention relates to logistics equipment, especially a double-layer vertical conveyor, a double-layer sorting system and a sorting method thereof. Background technique [0002] The cross-belt sorting system is connected 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 rotates 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 sorter. [0003] Conventional cross-belt sorters, such as the circular cross-belt sorter with application number 201620688482.9, usually have a structure laid horizontally on the ground. This structure occupies a large area and is difficult to use in small spaces. Adaptation, poor application flexibility. [0004] In view of this, more and more companies are vigorously resea...

AI Technical Summary

Problems solved by technology

[0005] Because the trolley moves along the circular track, when the trolley is at a high position, its conveying surface can carry out the conveyance of goods. When the trolley rotates to the corner of the circular track and the lower position, at this time, the conveying surface of the trolley is inclined or downward. Items cannot stop on the conveyor line, therefore, items must be transferred on the upper layer, but cannot be transferred on the lower layer, which greatly reduces the efficiency of the trolley and the flexibility of equipment layout
