Sorting device and method based on position tracking

Abstract

The invention discloses a sorting device and method based on position tracking. The sorting device comprises an encoder,at least two material detection sensors and an executing mechanism, wherein theencoder is connected to a driven shaft at the tail end of a conveyor for driving a main line to move, and is used for recording the position of a material conveyed on the main line; the at least two material detection sensors are arranged at an inlet of the main line and are respectively marked as a material detection sensor A and a material detection sensor B in the transportation direction of the main line, the distance between the material detection sensor A and the material detection sensor B is smaller than a preset distance, and the two material detection sensors are used for assisting the encoder in determining the positions of materials; and the executing mechanism is arranged at the intersection of a branch line and the main line, and when the materials are conveyed to the intersection, the executing mechanism drives the materials to the sorting branch line. According to the sorting device and method based on position tracking, the problem of material sorting errors caused bymisoperation of the material detection sensors is avoided.

Description

technical field [0001] The invention relates to the technical field of logistics transportation, in particular to a location-based tracking and sorting device and method. Background technique [0002] In recent years, with the rapid development of the e-commerce and express delivery industries, the market demand for automatic conveying and sorting equipment, one of the core equipment of the logistics system, has risen sharply, which has greatly improved the efficiency and accuracy of material sorting. Generally speaking, the automatic sorting and conveying system consists of the following parts: material detection sensor (usually photoelectric switch), shunt actuator (balance wheel, swing arm, transfer machine, etc.), controller (PLC, MCU), Alarm indicator lights, safety devices (emergency stop buttons, emergency stop pull ropes, etc.); some systems also include video surveillance systems. Usually, when the material is running to the corresponding sorting branch crossing, t...

Problems solved by technology

[0004] The purpose of the present invention is to provide a sorting device and method based on position tracking, so as to avoid the misoperation of the material detection sensor itself, or the abnormality of the upstream actuator, so that the material is not sorted into the upstream crossing, and still stays on the main line The materials will affect the downstream tasks and cause information confusion, which will lead to the problem of material sorting errors
