Double-loop-line intersected belt sorting machine, intersected belt sorting system and sorting method thereof

Abstract

The invention discloses a double-loop-line intersected belt sorting machine, an intersected belt sorting system and a sorting method thereof. The double-loop-line intersected belt sorting machine comprises at least one annular rail, two sets of intersected belt cars for forming two conveying loop lines circularly rotated on the annular rails side by side, and a power device for driving the two sets of intersected belt cars to move along the annular rails. The double-loop-line intersected belt sorting machine is delicate in design and simple in structure; as two sets of cars are used in one annular rail, the number of the intersected belt cars is increased by using internal space of the loop lines under the precondition of not increasing the floor area to multiply the sorting capacity, theuse efficiency of the sorting machine is improved, and the equipment cost is reduced; and meanwhile, parcels can be transferred between two conveying annular intersected belt cars, so that the idlingrate of the cars can be reduced, meanwhile, the parcel loading flexibility is improved, and the arrangement requirements and the occupied space of a particle loading line are reduced.

Description

technical field [0001] The invention relates to the field of logistics sorting equipment, in particular to a double-loop cross-belt sorting machine, a cross-belt sorting system and a sorting method thereof. Background technique [0002] Sorting is the operation of stacking items in different categories according to the type, sequence of entry and exit, and destination. Sorting is the preparatory work of improving delivery and supporting delivery, and it is an inevitable extension of different delivery companies to compete and improve their own economic benefits during delivery. Therefore, it can also be said that sorting is an inevitable requirement for the development of delivery to an advanced form . [0003] In order to improve sorting efficiency, automatic sorting systems were widely adopted in logistics distribution centers in the United States, Japan, and Europe after World War II. Among them, the cross-belt sorting system, as shown in the application number 201810494...

AI Technical Summary

Problems solved by technology

[0003] In order to improve sorting efficiency, automatic sorting systems were widely adopted in logistics distribution centers in the United States, Japan, and Europe after World War II. Among them, the cross-belt sorting system, as shown in the application number 201810494195.8, It is connected by the main drive belt conveyor and the trolley (referred to as "trolley") carrying the small belt conveyor. When the "trolley" moves to the specified sorting position, it turns the belt to complete the sorting of the goods. Although the sorting task greatly improves the sorting efficiency, the system itself needs to build a mechanical transmission line with a short length of 40-50 meters and a length of 150-200 meters, and the transmission line is laid horizontally in a circular shape, covering a large area , the internal space of the ring line is not fully used, so the requirements for the site are high and the site utilization rate is low, and the application flexibility is poor

[0004] In addition, the existing trolley driving method is often the way of motor + sprocket + chain. On the one hand, the trolley needs to be connected to the chain, which increases the difficulty of assembly. On the other hand, due to the pitch limit of the chain, the gap between the trolleys Relatively large, resulting in a reduction in the number of trolleys; and, due to the limited number of power points, in order to ensure sufficient driving force, the length of the chain often needs to be controlled within a reasonable range, and the limitation of the length of the chain gives the extension of the ring line. To hinder, not conducive to the expansion of the line
